Washing machine power: how many kW does it consume?

To find the right model for yourselfmachine-machine, it is worth considering several mandatory criteria. Many consumers, choosing this type of home appliances, primarily pay attention to the volume of drum loading and the availability of the necessary washing regimes. Not the least role should be played by the power of the washing machine. After all, it is this category that determines the amount of electricity consumed during washing. Having made the right choice and observing certain rules of using the device, you can significantly save on paying utility bills.

How to determine the power of the washing machine when buying?

Each model has its own class of power consumption. It is assigned after testing the technique in the laboratory. For washing machines this is the amount of kW / h per kilogram of loaded laundry. The energy efficiency scale has its own generally accepted designations: "A", "B", "C", "D", "E", "F", "G". The best class "A" can be supplemented with special "+" signs, which indicate the minimum energy consumption.

When buying in the first place is worth payingattention to the sticker. As a rule, it is located on the front side of the case or in the passport of the device. It contains all information on the energy expended during operation.

If you determine the class of your owntechnology is not possible, learn the power of the washing machine in kW help the seller consultant. Most often today there are automata class "A", "A +", "A ++".

What elements of the washing machine affect its capacity?

To determine how much electricity will be consumed during washing, it is worth investigating why it is needed.

The power consumption of the washing machine consists of the consumed electricity of such components as:

1. Engine. It is responsible for the rotation of the drum. The higher the RPM, the higher the power consumption. Also the power of the engine of the washing machine depends on its type. Asynchronous, which were used in the old models, today almost do not occur. Their power was not more than 400 watts. Collector motors, most often found in modern models, as well as brushless (inverter), which are directly attached to the drum (used by LG) consume up to 800 watts, depending on the washing schedule and the program selected.
2. Heating element (TEN). It accounts for most of all consumed electricity, since modern models are only connected to cold water and kW is used to heat it to the required temperature. Today, washing machines use heating elements, the power of which reaches 2.9 kW. The power consumption depends on the selected program and the wash cycle. The heater can generally not consume electricity, for example, during rinsing or spinning, and for heating water to 90 ° C its power will be used to the maximum.
3. Pump. It pumps out the water used during the various washing cycles. It accounts for up to 40 watts.
4. Washing machine control system. More electricity will be consumed in washing machines with electronic control (where there are screens), up to 10 watts. But for mechanical control, up to 5 watts is required (different light sensors, programmer, control buttons, etc.).

Does the power of the device only affect the power consumption?

It is important to take into account the operating conditions. As can be seen, the largest consumed power is the electric motor of the washing machine and its heating element. But in combination, the power consumption depends on the selected program, washing modes, drum loading, and on the state of the components.

What other factors affect the power consumption during washing?

The power consumption of the washing machine isbasic, but not the only indicator, which should be based on the calculation of the costs spent for the implementation of the washing program kW. In addition to washing programs that have different temperature conditions, power consumption also depends on:

1. Type of fabric. As a rule, the choice of the program depends on it. Also, different materials have different weights when wet.
2. Water temperature. Although all modern models are connected to cold water, but its temperature, especially at different times of the year, is different.
3. Number of revolutions. This figure affects the energy expended by the engine of the washing machine.
4. Degrees of drum loading. Modern models with intelligent control are able to calculate the weight of the laundry loaded into the drum and collect the appropriate amount of water. Otherwise, no matter how many things are loaded into the car, it will use the amount of water determined by the program.

How to save electricity?

The consumption of kW during washing is affected not only by the power of the washing machine, but also by the way it is used. To save on utility bills, you should follow a few simple rules:

1. Try to load the drum completely, if the model does not provide intelligent control. Thus, with each wash, you can save 10-15% of wasted electricity.
2. Competently choose a washing program. For example, it is better to wash lightly soiled items in the quick wash at 30˚ C, than the program "Cotton" at 60˚ C.
3. Clean the heating element from scale. Once a six months to run the program "Cotton 60˚ C" without linen, pre-laying a means to cleanse of scale.

Conclusion

The power of the washing machine in kW can be found out when buying, paying attention to the colored sticker on the front side of the housing of household appliances.

It can range from 2 to 4 kW. There is a special scale of energy efficiency,which divides into classes all electrical appliances. The most economical - "A" and "B" class. In the process of operation it is important to understand that it is not enough to know the power of the washing machine to calculate the amount of electricity consumed, it is necessary to follow certain rules that will help to cherish the treasured kW.
