We think that we will not lie if we say that almost every person on the planet knows what a washing machine is, of course, if this person lives in society, and not in the deep taiga. Yes, and in the taiga, they probably already know about washing machines. We all use them, but few of us have thought about the principle of operation of a washing machine. Today we want to tell you how the automatic washing machine works, what washing processes the laundry goes through and we think that you will like it.
We will tell in the order in which this process takes place, that is, for you it will be as if you are participating in the process of washing your laundry and watching it from the side.
Start washing
It all starts with the fact that we load laundry and powder into the washing machine, open the water supply tap, and then select the washing program. Once you have selected the wash program and pressed the start button. The program module has received a signal from you that it is necessary to start washing. The washing process has already been laid down for him and will be carried out according to a certain pattern, which you have selected (washing programme).
First of all, the load hatch is blocked to prevent accidental opening during the washing process. Next, a signal is sent to the water supply valve, which opens. At this time, water begins to flow into the powder receiver and wash the powder from the tray into the tank.As a result, the tank is filled with water.
The washing machine has a water level sensor that determines how much water is in the tank and as soon as the sensor is triggered, the water supply valve closes. Everything, now it turns out that there is water with powder in the tank, and dirty laundry in this water lies in the drum. The machine is ready for washing.
The principle of operation of the washing machine drum
To make it clearer, we will tell you how the tank and drum are arranged. A tank is a kind of reservoir, like a barrel, inside of which there is a drum. Water is filled into the tank, and it enters the drum through small holes with which it is all permeated. The tank always remains stationary and the drum is driven by a motor through a belt. To remove washing machine drum, you always have to disassemble the tank, and nothing else.
If this LG is direct drive, then the whole thing does without a belt.
washing machine washing process
We have laundry in the tank, water and powder too. And the programmer gives a signal to start the rotation of the engine. The motor starts to rotate the drum of the washing machine. What is going on inside at this moment?
The drum starts not only sloshing water, but also turning the laundry using special metal protrusions inside the machine, you can see them below in the photo.
There is a mechanical effect on the linen, similar to what we do when we wash clothes by hand. Only compared to hand washing, everything happens much faster and more efficiently.
Since washing on many programs takes place with warm and hot water, the electric heater turns on, which heats the water until it receives a signal from the temperature sensor that the water has heated up to the required temperature.
TEN - a tubular electric heater is located at the bottom of the tank and is intended only to heat water.
The washing machine makes a certain number of revolutions in a certain direction, at a given speed, depending on the program you have set.
Draining and rinsing clothes
After the wash program template is finished, the programmer sends a signal to the drain pump so that the latter starts pump out water and drain it down the drain through the drain hose. Dirty water is being drained. The pump runs until a signal is received from the water level sensor that there is no more water in the tank.
After that, the rinse cycle starts. Similar to the beginning of the wash, water is supplied to the tank, only this time without powder, instead the machine washes away the rinse aid container. Water enters the tank again, and the machine starts rotating again according to a given program. The process can be repeated, the machine can fill and drain water more than once, depending on the rinse mode.
After the machine has finished rinsing, the water is again drained into the sewer and the spinning process begins.
Spinning clothes
As the washing and rinsing program is over, the laundry spinning program is turned on (provided that it is not turned off for you). The principle of operation of the spin cycle based on the laws of physics: the drum spins up to high speeds (usually 800-1600 rpm on different washing machines). The centrifugal force begins to push the laundry outward, pressing it against the drum, and at the same time all the water in the laundry is pushed out.If the linen itself has nowhere to go beyond the aisles of the drum, then the water through the holes in the drum goes beyond its aisles into the tank, where it flows to the bottom of the tank and is pumped out into the sewer. Accordingly, the higher the spin speed, the more water will come out of the laundry and the laundry will be drier.
As you understand, the laundry unwinding in the drum creates an imbalance, forming the eccentric principle. In order for the machine not to vibrate strongly, heavy counterweights are installed on the tank, which compensate for this load.
The spin speed of the laundry on different programs may be different, for delicate fabrics the spin will be at lower speeds or completely disabled, for fabrics that do not require special care, the spin will be maximum. You set all these parameters by choosing the washing program at the beginning.
End of washing
After all washing, rinsing and spinning programs are finished, the machine ends the program. But before that, it makes several rotations of the drum so that the laundry is evenly distributed over the drum. The machine stops, but you can't open the door. The lock has a lock, which is removed 1-2 minutes after the end of the program. After this time, the hatch lock is unlocked and we can get things out of the typewriter and go hang them.

We have described the principle of operation of the automatic washing machine quite simply, from the point of view of a simple layman without going into technical details. After reading this article, you will understand the general principles and will know how the washing machine works.If you want to delve deeper into this topic, then read about washing machine device on our website.
