Today, probably, there will no longer be those who do not have a washing machine at home, but few know the design of the washing machine. And when it breaks we do not know what exactly the problem is. In this article, we will consider the automatic washing machine device, so that in which case you can independently identify breakdowns and repair the device.

Washing machine device

If you still do not know how the washing machine is designed, then in this article we will talk in detail about each of its elements. Conventionally, all the elements of a washing machine can be divided into several main groups, which include various structural elements:

electronics group and machine control module;
executing elements of the device;
drum compartment of the washing machine;
case and other elements.

Below we will consider each of these groups separately.

Electronics Group and Machine Control Module

Consider the most important module in the washing machine, the machine that is responsible for the performance of your device, namely the control module. This board is fully responsible for all systems of the device, and gives all other structural elements commands to perform any operations.

It contains a list of all available programs, and other program codes for the system. If this control unit fails, then replacing it will cost you a large amount.

However, the control board cannot function without some individual elements that perform certain tasks, namely the following devices:

Sensor for determining the tank filling level (pressure switch) - as the name implies, this element is responsible for transmitting data on filling the tank with water. This device works in combination with an air chamber that supplies pressure to the sensor, depending on how full the tank is.
Thermostat or temperature sensor - it is mounted at the bottom of the washing machine and is designed to determine the temperature of the water that enters the main compartment.
Tachometer - Designed to control engine speed. It is through him that the command unit controls the number of revolutions of the drum for various washing programs.
Other electronics - this item can include the front panel, with the display on which you select the program. Also included are relays with wires connecting all the structural elements of the washing machine.

Performing elements of the device

The control unit betrays all commands to these elements, which perform the bringing of the entire mechanism into action:

The lock on the door - before the washing process starts, the system sends a signal to the door, and it is blocked until the end of the preset wash program.
Water supply valve - also known as a solenoid valve, it is also controlled by the command unit, and by signals it unlocks and lets water into the drum compartment, and also closes after the signal is stopped.
Engine - the most basic element, without which the functioning of the washing machine is impossible. It drives the drum in which the laundry is located. In washing machines, it transmits torque in different ways - through a belt drive, or directly, driving a drum pulley. The number of revolutions and the direction of rotation is controlled by tachometer which sends information to the command module.
TEN (heating element) - heats the water to the specified temperature, which is transmitted to this element through the command block. A tubular heating element (TEN), when in contact with water, becomes covered with scale, which subsequently heats the water poorly, and may completely fail.
Drain pump - Designed to drain already used water into the sewer system.

Drum compartment of the washing machine

The largest element that takes up the most space in the washing machine is due to the fact that it must hold water for washing and several kilograms of laundry. The tank itself is made of plastic, and is a relatively sealed container, inside which there is a movable drum along with a heating element.

Due to the fact that the tank is quite heavy and without laundry, it is equipped with shock absorbers and special spring fasteners that rigidly fix it in an inactive state and allow it to perform working operations during washing.

The ram itself is a structure made in the form of a cylinder, with holes inside in the form of a mesh throughout the cavity of the drum. Made of stainless steel.

Case and other elements

All the main elements have already been described above, it remains to describe only small elements:

Powder supply box - this compartment is a tray or hopper to which various nozzles and other elements for supplying water are connected.
Counterweight Plate - due to the fact that during the spinning of the laundry, the drum rotates at high speed, this entails the fact that the machine is actively moving. It is for this that a weighting plate is mounted that does not allow the machine to move.

That's actually the whole device of the washing machine is automatic, now you know the design of the unit, and what elements are in it and what they are responsible for and what functions they perform.
