The power consumption of the washing machine is determined by the class, it implies information on the amount of electrical energy consumed during one cycle of the procedure in case of maximum load.

Subtypes of machine energy consumption

Based on the specified information, they are guided, estimating the efficiency of the unit. It is possible to obtain information by subtracting the corresponding marking located on the body of the unit. Invented by Europe 7 levels of energy consumption, denoted by labeling in Latin letters: A; V; WITH; D; E; F; G. A plus is added to aggregates that exceed the skill limits of the standard.

• Units A are extremely economical, equipment of subspecies A requires 0.17 - 0.19 kWh.
• The consumption of a class B washing machine varies between 0.19 and 0.23 kWh.
• Devices of the type C 0.23 - 0.27 kWh spend a little more resources.
• Household appliances of subspecies D belong to the economical category, the level of "fence" varies between 0.27 - 0.31 kWh.
• Devices showing indicators E-F, are characterized by increased demands, the consumption level is 0.31–0.35 kWh, 0.35–0.39 kWh, respectively.
• Let's call class G devices uneconomical, they are able to "take" more than 0.39 kWh, an extremely large amount, unjustifiably.
• The antipode, the complete opposite, is the technique of category A +. "Occupies" less than 0.17 kWh, ensuring the competitiveness of products.

How much a washing machine consumes is determined by laboratory research, and the appropriate level is assigned to the technique.

"P" value

Power, which determines the rate of energy consumption, plays a key role. Washing machines show performance in the range of 2–4 kW. High figures are due to the need to heat water, they have special requirements for connecting equipment. It is associated with restrictions regarding the current passed by the wires. The power of the washing machine is 2.2 kW, the current consumption is 10 A. The throughput of copper wires is 14 A / mm 2, the parameter for aluminum wiring is 10 A / mm 2. The device, which consumes 2.2 kW, is connected, having previously calculated the cross section of the cores.

If the P of the technique exceeds the cable's capacity, you will need to convert the figure to amperes using the formula: N (kW) × 4.35 \u003d A. Empirically it looks like this: 4 kW × 4.35 \u003d 17.5 A. Divide the result by the number of square millimeters, above. Compare relevant information. We conclude: connecting a machine with power

It is carried out using an aluminum wire with a core cross section of 2 mm 2 or a copper wire with a cross section of 1.5 mm 2.

Ratio of maximum power and energy

Now consider the ratio of the maximum required power to the energy costs of the cycle. The largest

The unit ranges from 2.15–2.3 kW. At the maximum setting of the physical value, the consumption is 0.94-0.95 kWh. The indicators of devices of classes B, C are identical. The power consumed by the washing machine rarely exceeds 2.2 kW, allowing you to count on resource consumption of 0.9 kWh. Cardinal differences are felt in the case of equipment belonging to subspecies D in this case, the “max” power level can also be 2.2 kW. The consumption reaches 5.2 kWh, which is extremely high.

Calculation of electricity consumption based on the power of the device

What do the installations mean for the average consumer in terms of the number of kilowatts needed during the month. The following simple scheme will help to simplify the understanding of the issue: 1000 Wh \u003d 1 kWh. In other words, the device has the largest

4000 W, for 1 hour of work will consume 4 kWh of electrical energy. Measurements of the required amount

One cycle conditional. The consumer is informed how much energy the device will consume, operating for an hour, heating water to a temperature of 60°C.

Therefore, the power consumption of a washing machine is determined by additional factors:

1. fabric type;
2. water temperature;
3. number of turns;
4. drum load.

If it is indicated on the unit: “takes” 0.94 kWh, this is how much the device will use during an hour of operation at a water temperature of 60 ° C, fully loaded with cotton fabrics. If the procedure is carried out at a temperature of 30 ° C, other things being equal, 0.47 kWh is spent.

Conclusion

The energy consumption of the washing machine is directly determined by the maximum power, the actual electricity costs are determined by the operating conditions of the equipment. Information concerning limit value

Consumption under standard conditions (cotton fabric; t=60°C), marked with a special sticker. Based on the information provided, the consumer will choose the optimal mode of operation that meets the requirements regarding the quality of the procedure, the need for electrical energy. Proper use of information will save money on the maintenance of the machine, help optimize family budget. Focusing on the numbers of the sticker, making the right choice, acquiring an acceptable technique for washing clothes.

The greater the functionality of the washing machine, the more electric motors and heaters are installed on it. This predetermines the power of the unit. It is not at all necessary that the efficiency of energy consumption will increase with an increase in the power-to-weight ratio: there is no direct dependence here. The determining indicator for evaluating the efficiency of household appliances is their classification according to the specific energy consumption per conditional amount of work performed. The energy efficiency class assigned to the devices is indicated directly on the equipment case.

The washing machine is a complex device. It consists of several elements that consume electricity, the power of which is measured in watts:

1. Washing drum drive motor. Today, such motors are presented in a collector version with direct drive, they have replaced the previously used asynchronous motors. Their power is in the range of 0.4–0.8 kW, and large values ​​refer to the “spin” mode.
2. Tubular electric heater (TEH) for heating water. Depending on the water heating temperature in different modes, its installed power can be 1.7–2.9 kW. The more powerful the heating element, the faster the water in the tank heats up.
3. Electric pump for pumping water from the tank. Its load is 25–45 W.
4. Control panel with LEDs, bulbs and sensors with a total output of up to 10W.

By summing up the load from individual electrical receivers, determine the installed power of the washing machine. It will turn out to be much more consumed for several reasons, the main of which is the multi-time operation of each individual engine. The operating time is not a constant value, but depends on the selected program, just like the water temperature. Another parameter that affects the power is the type of fabric being washed and its weight.

According to the installed power of the washing machine, the parameters of the devices used to connect it to the electrical network are determined. With a total load of the machine of 2.5 kW, the current in the wires will be 2.5x4.35 = 10.9 A. According to the estimated current in amperes, a safety circuit breaker is selected - protection against overloads in the electrical network, and the cross section of the connecting wires.

To compare energy efficiency various types washing machines, the power consumption is calculated for the maximum load of the drum in the “cotton” mode at a water temperature of 60ºС (average temperature for different modes). The energy consumption class is denoted by the letters of the Latin alphabet A, B, C, D, E, F, G and is measured in kilowatts consumed per hour (kWh). Economy Class A cars are subdivided into A+, A++, A+++. Their energy consumption values ​​are in the range of 0.13–0.19 kWh. The most expensive G index, its performance exceeds 0.39. The calculation of quantitative values ​​and the assignment of the corresponding energy classes to washing machines takes place in laboratory conditions per 1 kg of laundry washed.

How to calculate approximate electricity consumption

To get an idea of ​​the expected payments for the use of electricity in terms of the cost of washing clothes, you need to know the power of the washing machine, or the specific electricity consumption per 1 kg of laundry. There are two ways to calculate:

1. The power of the washing machine can be seen in the product passport or read from the body sticker. Knowing the number of washes per month and average duration single procedure, determine the total elapsed time in hours. Electricity consumption is determined by multiplying power (kW) by time (hour). The dimension of the obtained value is kWh.
2. The specific energy consumption per 1 kg of laundry is determined by the energy consumption class of the machine, information about which is contained on the body of the device and in its passport. The second value needed to calculate the electricity consumption for washing is the number of things washed per month, expressed in kilograms. By multiplying these two values, you can get the desired power consumption for one month.

There is another option for calculating the second method: by the number of laundry for one wash and the number of procedures per month, determine the total weight of the clothes washed per month, and then multiply by the energy efficiency class indicator of the device. In any case, this will only be an estimate of the energy consumption for washing, but the information on the energy class is a good hint when choosing the optimal power of the washing machine.

I am standing in front of a window with washing machines in thought: buy cheaper or energy class A and save on water and electricity consumption in the future.

The energy consumption classes of washing machines are indicated in English letters, in some models they add a “+” sign. What do these symbols mean, what energy is spent by household appliances, its energy efficiency - you will learn all this information in this article.

The power of the washing machine can be found on the sticker, which is located on the back of the appliance, indicated by the parameter in kW / h. From its value, you can find out how economical the device is.

In the modern world, everyone should have energy savings in the first place, and this includes the choice of a washing machine, because it is a fairly powerful device. Information about the energy consumption classes will help you find the best option.

What is the power of the washing machine?

The power of the washing machine is the sum of the load carried by the individual drives:
• tubular electric heater (TEN);
• drum rotation motor;
• pump for pumping water out of the tank.

In addition to creating thermal and rotational energy, a certain amount of watts is consumed by the control unit and information support of the apparatus.

A simple summation of the loads of each of the consumers will make it possible to find out the installed power of the washing machine: its value will be maximum, but not reflecting the true power consumption.

The fact is that the drives in the machine work at different times: first, the heating element is turned on, after it is disconnected, the drum rotation motor starts, and at the end of the cycle, a drain pump is introduced.

The result is a certain average load, which is called operating power. It is attributed to 1 kg of washed linen, and according to this indicator, the energy efficiency of the device is judged.

You can determine how many kilowatts of electricity your machine will consume by technical specifications. They are located on the body sticker or in the manual manual.

You can also find out the power by the letter marking of the washing machine of a particular model. It is indicated on the energy efficiency label according to the EU - DIRECTIVE 2009/125 / EC, indicating the main consumer properties of the product.

To get an idea of ​​the total electricity consumption of a washing machine, you need to see the values ​​for each pantograph. There are four such devices in the device:
• The drive motor of the working body is a drum for frontal units and an activator for vertical units. Motor power is measured in watts, and this value varies depending on the brand in the range from 180 to 800 watts.
• TEN - its power is several times higher (1.7–2.9 kW), but it turns on only for the time of water heating. However, it is the second most important resource consumption component.
• The drain pump operates in short-term mode, has a low power characteristic - from 24 to 40 watts. Its share of the cost is insignificant.
• The control unit, sensors and relays, light indication in total bring a load of 5–10 W.

Thus, the maximum value - the installed power of the washing machine - can reach 3.7–4.0 kW. While the average (distributed in the cycle) is in the range of 1.0–1.4 kW.

How many kilowatts does a washing machine consume

First you need to understand which parts of this household appliance consume electricity the most:
1. The electric motor is the "heart" of the washing machine. The task of this element is to give rotation to the drum. The main types of motors used in modern devices are collector, asynchronous and direct drive. Average power consumption ranges between 400 and 800 watts (0.4 to 0.8 kW).
2. TEN - serves to heat the water in the tank. It fully automates the washing and drying process. The quality of washing certain things depends on the choice of the correct temperature.
3. Pump (pump) - designed to pump out water at various stages of washing. The power consumption of such pumps varies from 25 to 40 watts.
4. The control panel, electronic module, programmer, various sensors, starting capacitors, light bulbs and other radio components are elements that together consume no more than 5 - 10 watts.

From the above, it can be seen that the main consumed electricity depends on the operation of the heating element and the electric motor. In turn, they will consume the amount of energy corresponding to the choice of the washing program.

The programmed modes differ from each other in temperature, washing duration, intensity, number of drum revolutions during washing and spinning, additional options (number of rinses, etc.).

Affects the power consumption and weight of loaded items and fabric types.

Many different factors affect the number of kilowatts consumed by a washing machine:
• Service life of household appliances. That is, the more the washing machine works, the more it accumulates formations on the heating element. Such formations significantly complicate the operation of the machine and the process of heating water, respectively increasing power consumption.
• The type of clothing and fabric also greatly affects the power consumption of the washing machine. The thing is that wet fabric differs from dry in weight, respectively, requires different consumption of electricity.
• The workload of household appliances greatly affects the consumption of electricity. The calculation of the amount of electricity consumed is based on one kilogram of laundry, therefore, the more you load the drum, the more power consumption the washing machine needs.
• The washing program also affects the electricity consumption. It also talks about the temperature that is necessary for washing. High temperatures will require a lot of electricity. A long washing process increases the number of kilowatts consumed.

Washing machine energy classes

Power consumption of washing machines, calculated in a practical way. The calculation was based on a full cycle of washing cotton linen at a temperature of 60 ° C and a loaded weight of 6 kg.

The classes indicate the efficiency index "C" of the use of electricity (kWh per 1 kilogram). The European Community has developed an energy efficiency scale from the letter "A" to the letter "G".

"A" and "B" are the most energy-saving classes. "C", "D" and "E" - average in terms of energy savings. "F" and "G" are the lowest in existence.

by the most best options today are "A+++", "A++" and "A+".

They provide maximum care for washing and energy.

A separate class is characterized by washing machines with the function of drying things.

The calculation is based on the same cotton cycle used by standard machines and the same index.

It is very unlikely that you will find household appliances that have been released in our time and which have been assigned a “G” class. After all, most modern manufacturers seek to reduce the consumption of manufactured electrical appliances.

How did the energy classification come about?

Energy efficiency classes that inform the consumer about the amount of energy and other resources consumed by household appliances have been operating in the markets of European countries for a long time.

This labeling system, first introduced by Directive 92/75/EEC of September 22, 1992, covers household appliances such as refrigerators, washing machines, dryers and dishwashers, ovens, hoods, vacuum cleaners, air conditioners and televisions.

At first, energy efficiency classes were designated by letters from A to G, but later, as the efficiency of devices increased, classes A +, A ++ and even A +++ were added to the gradation, and classes E, F and G were removed from the stickers - so wasteful models are no longer produced.

In 2010 - 2012 there has been a gradual (at first voluntary, then mandatory) transition to new energy efficiency stickers. These stickers are designed and approved by the CECED (Conseil Europeen de la Construction d'appareils Domestiques) European Association of Home Appliance Manufacturers.

The transition to the new stickers is in many ways in line with the European Union directive aimed at achieving the goals of the 20-20-20 program: reduce primary energy consumption by 20%, increase renewable energy production by 20% and reduce emissions carbon dioxide by 20% by 2020.

Even twenty years before the end of the last century, buyers began to be more and more interested in questions not only of the quality of household appliances, but also of the amount of resources consumed by it.

Economy is a smart approach. And the desire to get the same result by spending less money on electricity is quite understandable.

Therefore, many manufacturers of household appliances began to supply their products with information on energy consumption. This information did not then have a single classification and could vary in different countries and brands.

Two or three years ago, the most economical class was the one that was designated by the letter "A". Then a new and more economical class appeared - "A +". And after it "A ++", in some types of household appliances a new and more modest class "A +++" has already appeared in terms of electricity consumption. Probably, in the near future there will be more devices with such markings.

Factors influencing profitability

The actual power consumption depends on the conditions of use of the washing machine and the preferences of its owner. The most significant impact elements:
1. The choice of washing mode directly affects the amount of energy consumed - increased temperature and maximum spinning speed means increased power consumption, the duration of the cycle and the number of rinses determines the duration of the load.
2. Drum load - the energy consumption class is set from the electricity consumption per 1 kg of laundry when the machine is completely filled. Systematic underutilization of the working volume will lead to an excessive waste of power in one wash.
3. Fabric - some types have the ability to absorb a lot of water and become much heavier. As a result, the machine works in heavy duty and there is an increase in energy consumption.
4. The state of the heating element - scale reduces the efficiency of heat transfer, which leads to power losses.

For some time now, information about the level of energy efficiency of household appliances has been an integral part of the equipment parameters presented on the label.

The main energy consumption classes of washing machines are: A, B, C, D, E, F, G. Over time, the efficiency of electrical equipment has increased, but the scale has remained unchanged. As a result, a new designation of the most economical devices appeared: the same letter A, but with the addition of one or more pluses (A +, A ++).

Let's start with the most economical option. Class "A ++" needs the most minimal amount of energy. Such machines need less than 0.15 kWh per kilogram of laundry.

The letter "A" means that electricity consumption will be in the range from 0.17 to 0.19 kW / h per kg of laundry.

Energy class A what is it

Consumers look at this indicator even more often than at the efficiency index of a washing machine. On average, a family's washing machine runs up to 5-6 hours a week. Approximately 20 hours a month. And, of course, everyone wants to reduce energy costs.

Recently, manufacturers have paid much attention to this indicator. And if earlier washing machines were classified into seven groups in terms of energy consumption, then since 2002 they began to produce A + class machines. This is the most economical option, which consumes 0.17 kWh/kg.

To assign a washing machine an energy class, tests are carried out. Washing machines are loaded with 1 kg of cotton laundry. The linen is washed for 1 hour at a temperature of 60 C. At the end of the wash, the amount of energy consumed is calculated. Depending on this indicator, the machine will be assigned an energy class.

The energy classes of the washing machine are indicated by the letters of the English alphabet. By the way, the same letters denote the spin and wash classes. Also, when marking, the “+” sign (s) next to the letter “A” can be used.

These classes are determined by laboratory tests with a washing machine. For this, a machine is taken, cotton linen is placed in it and the washing temperature is set to 60 degrees Celsius.

From the results of washing, indicators are derived, which are indicated in kW / h per kilogram of washed items.

Energy class B

The higher the spin speed, the more the motor consumes. In addition, loads are growing, which leads to an increase in energy consumption. Additional costs within one wash will not be noticeable, but frequent washing will cause a slight increase in the numbers on the electric meter.

From all of the above, we can conclude that the most economical, inexpensive and practical are class B automatic washing machines, with a spin speed of up to 1000 rpm.

For a machine with the designation "B", you need 0.19-0.23 kW / h / kg.

Energy class B what is it

The energy efficiency class of the washing machine depends on the amount of electricity that the appliance consumes in basic mode to wash 1 kg of cotton laundry for 1 hour at 60°C.

The lower this indicator, the higher the class of the washing machine in terms of energy consumption.

After 2010, instead of the energy class, a new characteristic was introduced - the energy efficiency class. This indicator depends on the Energy Efficiency Index (EEI).

To assign a value to the new model, average figures for electricity consumption per year are used. Take into account washing modes at different temperatures and partial loads. When calculating, it is assumed that the machine goes through 220 complete cycles per year.

The standard consumption (100%) of electricity for a full cycle (with a load of 6 kg of dry linen made of cotton fiber) is 1.52 kWh, that is, 334 kWh per year.

The energy efficiency class is

The energy efficiency index is the percentage of the actual electricity consumption of a particular model to the standard one. The higher the aggregate class, the lower the index value.

In order to find out how much electricity a particular washing machine consumes per year, it is enough to multiply the reference consumption (334 kWh) by the index corresponding to the energy consumption model class and divide by 100.

Energy efficiency - efficient (rational) use energy resources. Using less energy to provide the same level of energy supply to buildings, or technological processes in production.

Achievement of economically justified efficiency in the use of fuel and energy resources at the current level of development of engineering and technology and compliance with environmental protection requirements. This branch of knowledge is at the intersection of engineering, economics, jurisprudence and sociology.

Unlike energy saving (saving, saving energy), mainly aimed at reducing energy consumption, energy efficiency (usefulness of energy consumption) is a useful (efficient) use of energy.

More importantly, each type of appliance or device has its own energy efficiency scale, and it is impossible to compare, say, a refrigerator, a washing machine and a car, because the energy efficiency of these products is calculated based on different principles.

The regularly rising cost of utilities is forcing users to look for economical household appliances. In this case, one of the main parameters is the power consumption of the washing machine, which is chosen in an apartment or house. Even the lower initial cost of an energy-intensive model can be offset by its “voracity” in the future.

Classification of household appliances

The automatic machine belongs to one of the classes of consumers of electricity. Classes are available from the most uneconomical G to the most economical A. The latter has an additional gradation in the form of pluses. The most economical is considered to be A +++.

The power of washing machines and their class are usually indicated by the manufacturer on the sticker. It is fixed on the front side of the equipment. The values ​​apply not only to washing machines, but also to dishwashers, refrigerators and other electrical appliances.

You need to know that the model BOSCH, HOTPOINT ARISTON, INDESIT, SAMSUNG or other brands have the same energy intensity gradation.

The actual consumption of electrical energy per 1 kg of dry laundry is calculated in the laboratory conditions of the company. Further, the consumed power is checked against the parameters of the efficiency class, after which it is assigned an index.

To know how much a washing machine consumes and which class it belongs to, use the established scale:

• "A++" is the most economical group of equipment. It needs a minimum current consumption. She needs 0.15 kWh of power to process 1 kg of soiled dry clothes.
• "A +" - also an economy class. The equipment group needs a power input of 0.17 kWh for 1 kg.
• "A" - economy class. When this designation is used, the power of the washing machine in the group will be in the range of 0.17-0.19 kW / h.
• "B" - the equipment group includes washing machines that have an energy consumption class of 0.19-0.23 kW / h.
• "C" - under the logo there is a technique that needs 0.23-0.27 kW / h to process 1 kg of dry laundry.
• "D" - there are instances in the group that can spend from 0.27 to 0.31 kW / h.

When machines need more than 310 watts to wash 1 kg of laundry, they fall into the lower categories. However, modern machines of such parameters are no longer produced at any enterprises.

Design parameters

Let's figure out what power is calculated. In laboratory conditions, for the purity and stability of the experiment, washing the drum of things made of cotton is tested. At the same time, the water temperature is heated to 600C in order to obtain the most objective result. Such values ​​are reference.

The actual power consumption of the washers is also indicated on the information tag on the front side. This parameter can be either 2 or 4 kW. This value is at the maximum loaded drum and high temperature of water heated by heating elements. The washing machine does not always operate at full capacity, consuming the specified value.

The maximum consumption value for class A is 2.3 kW. So, when the machine is designed to process 5 kg of dry laundry, then according to the standard there will be about 0.1 kW per hour. This value is quite close to class "B". It is not always worth overpaying for such a value.

Additional factors

Scheduled drying or additional soaking will increase energy consumption. However, it will not exceed the set value of 2.3 kW, since it provides for certain combined modes of operation.

Power consumption is influenced by the following factors:

• The preset wash mode to use. In each case, it has a certain time interval, the temperature of the water heating, the intensity of the drum. It is important to know that washing machines with low power heat the water for a longer time and spin less efficiently. This forces users to run limit modes more often, which affects the intensity of equipment wear.

Costs directly depend on the selected mode and water heating temperature - the higher the degree, the greater the flow

• Material type. Things from different fabrics need different washing modes. Appropriate programs are used for them, because even when wet, the fabrics weigh differently.
• The presence of additional functions. When using additional operations, which include ironing, rinsing or drying, power is consumed from the network.

Determination of power consumption

To know the number of kilowatts consumed, it is necessary to identify all internal energy consumers. Popular blocks include:

• Electrical engine. It is the main element that needs energy. His task is to rotate the drum. Manufacturers use several types of motors: asynchronous, collector or direct drive. On average, they consume power from half a kilowatt to 0.8 kW. In the operating mode, there is a lower consumption, with a high-speed spin - more.

• TEN. One or two built-in elements are used to raise the water temperature. Thanks to them, there is a maximum automation of processes. There are modes (washing in cold water or rinsing), which do not imply the inclusion of heating elements. There are also programs in which electricity flies away, for example, during heating to 90-950C. The power consumption of heating elements is from 1.6 to 2.8 kW. The larger it is, the faster the heating occurs.
• Water pump. The product is necessary for pumping liquid from the drum at various stages of the process. Depending on the models, they consume about 20-40 W, which has a negligible effect on the overall consumption.
• Control Panel. All kinds of displays, sensors, luminous elements also consume power. Together, the programmer and all electronics “eat up” no more than 10 watts.

When choosing a washing machine, it is necessary to focus on the power consumption of the heating elements and the drum.

Unauthorized electricity consumption

Consumers do not always take into account the consumption of equipment, which also affects the power consumption:

• Remaining connected to the outlet, the machine consumes a certain amount of energy even after the completion of the washing cycles. It is advisable to immediately turn it off at the end of all cycles.
• Insufficiently loaded drum. It is better to do a couple of full washes than a few smaller ones with a small load. In the second case, power losses will be up to 15%.
• An incorrectly selected mode is able to "eat" up to a third of the power. It will also have a negative impact on costs.

Mode selection

• The dryer is in demand in cloudy, wet weather. During sunny days, you can save precious kilowatts by hanging your laundry outside.
• The service life of equipment and quality timely maintenance also have an impact.

Inverter-type machines differ in lower power consumption. They save up to 20% compared to traditional models.

To understand the consumption for the washing period, just look at the passport or the instructions for the household appliance. Next, we multiply the value set by the manufacturer by the operation time, we get kilowatt hours. If you multiply by the cost of the tariff, you can find out the price of the operation.

The power consumption depends on the power, which then has to be paid. The washing machine should fit into the overall interior of the room, be the main assistant in washing and cleaning, and reduced energy consumption will also make it a great friend to any housewife. How to choose a washing machine, later in the article.

A certain technical characteristic of a washing machine determines the amount of energy consumption in the amount of kilowatts per hour. Depends on this, and the capabilities of the washing machine, and energy consumption per month. The main characteristics are the class of washing, energy consumption and spin speed. Before choosing a machine, it is necessary to clearly understand in what mode the washing takes place in the house, for which washing the machine is bought. If dimensional things are erased or with difficult spots, then more powerful machines are bought. When washing occurs once a week and mostly soft fabrics, then you can take a more economical model.

To begin with, they determine which part of the washing machine and how much electricity it consumes.

For example, the “heart node” and the main organ of a washing machine is an electric motor. Thanks to this detail, the whole machine functions. He accelerates the drum in which the laundry is washed. There are 3 main types of electric motors for washing machines: commutator, direct drive and asynchronous. On average, the energy consumption of such motors is from 390 to 790 W (from 0.39 kW to 0.79 kW). If washing in normal mode, energy is consumed evenly. In the spin mode, more energy is needed to consume.

TEN (tubular electric heater) is designed to maintain the required temperature of water in the drum. With its help, washing turns into an automated process that does not need to be controlled. Competent housewives know how important it is to wash certain things at a strict temperature. If the cool water mode is selected for washing, then the heating element will not turn on, which means that the electricity spent on washing will be many times less. The power of heating elements in washing machines varies from 2 kW to 3 kW.

Another element of energy consumption is the pump for pumping water out of the drum. The energy consumption of such a part is small, about 5 watts. Low-power devices include the control panel, sensors and other parts that consume no more than 7 W when working together.

How to determine the power of the washing machine:

1. According to the technical passport or characteristics specified in the document;
2. At the consultant in the store where the purchase of the machine takes place;
3. Knowing the class, you can find out the power of a particular machine.

Drawing a conclusion, it can be noted that the greatest consumption falls on the engine and heating element. Before buying, please read technical specifications machine and its components.

Power consumption of the washing machine: energy consumption "past the checkout"

The machine washes without human intervention. The main thing is to choose the desired washing mode. Washing office shirts, choose the easiest mode, with a minimum of energy consumption. What will happen when washing with a huge sequence of programs: soak the laundry, evaporate, rinse additionally, and also dry and apply light ironing? The power spent on all these modes will be much greater.

What affects the increase in power during washing:

1. Selected program. From duration to temperature - all these parameters are individual for each washing program. Drying, ironing, rinsing, extra rinsing, gentle washing - the number of modes can be confusing. But, if you choose a machine with low power, you should prepare for the fact that it will wash longer and break faster.
2. Textile. Each material needs a certain sequence when washing. The fabric is also sorted by color and composition. You can not wash jeans with white shirts, unless of course these shirts are not for the country. Fabrics decide how many washes there will be and how many times the machine will run.
3. Each program has additional features. For example, light steaming after intensive washing or rinsing. These additional energy items also affect your monthly bill.

There are times when the consumption exceeds the expected number of energy consumption. Then you need to clarify what it causes. After work, the machine must be turned off. While in standby mode, power consumption continues. Of course, in modern models this detail is taken into account and minimized, but the ruble saves a penny. If the drum is not fully loaded into the wash, and the process is divided into several small operations, then this spends 25% of all energy.

It is better to choose a day for washing clothes and load the machine completely.

On sunny days, there is no need to use the drying function. Washed items can dry on their own. But, if this procedure is necessary, then get ready to part with the energy from the drying function. From such trifles, the total energy consumed by the machine is added. Thrifty housewives know that doing laundry every day is an expensive pleasure. Some things can be washed by hand, there is no need to run the machine.

Existing electricity consumption classes of the washing machine

The efficiency of energy and electricity consumption divides washing machines into classes: A-G. Class A is considered the most economical. The “+” signs indicate energy consumption. The highest efficiency of the machine with the class "A ++".

Energy consumption of the machine of each class per 1 kg of laundry:

1. “A++” consumes the minimum amount of energy: less than 0.15 kWh;
2. “A+” consumes less than 0.17 kW/h;
3. “A” consumes from 0.17 to 0.2 kW / h;
4. “B” consumes from 0.2 to 0.25 kW / h;
5. “C” consumes 0.25 to 0.3 kW / h;
6. “D” consumes 0.3 to 0.35 kWh;

And then in order to the smallest. Listing the entire alphabet of options does not make sense. Modern cars are designed to be very economical. The calculation of how much energy an electric machine takes on average takes place in the laboratory.

After all these procedures, the machine is assigned a power consumption class.

In laboratories, specifying the class of the product, they wash it at 60 ᵒC. Things are used from cotton fabric. The drum is loaded to the stop. The class is calculated only by washing the machine. The greatest opposite of economy is the “G” class.

Modern washing machines: class and power

The modern market offers a large selection of washing machines for every taste. From machines for industrial washing of uniforms, bulky fabrics or difficult stains, to compact models for soft fabrics for children and home clothes.

Front loading washing machine models:

1. LG. Class A+, power consumption 1.02 kW/h;
2. Bosch. Class A+++, power consumption 1.31 kW/h;
3. Samsung. Class A, power consumption 0.91 kWh;
4. Indesit. Class A+, power consumption 1.04 kWh.

Each machine has its own class and power. After studying the market, you can specify what the average capacity of the products offered. All these models represent a class of economical washing. Usually, the manufacturer sticks a sticker on the body of the machine. This helps the buyer to make a choice.

This sticker identifies all optional and important information which helps the seller to make a quick presentation of the goods.
