How does the washing machine wash?

All washing machines by type of basic workermechanism are divided into two large groups - the machine activator type and drum washing machines. Depending on how the laundry is loaded, machines are divided into front-loading machines and machines with vertical loading. By degree of automation, the machines are divided into automatic and semi-automatic. In our time, the most popular automatic drum-type machines with front loading. Therefore, first let's talk about how such machines work.

How an automatic washing machine erases

Machines of this type are permanently connected towater supply, sewerage and electrical network, so for washing in the car you just need to load things, fill the detergent with washing powder, select the suitable program and press the button, then the machine will do everything itself.

Operating principle

The most part of the machine is occupied by a metal tank, which on shock absorbers and

powerful springs are fixed inside the case. Inside the tank there is a rotating perforated drum, in which the process of washing and spinning takes place. Washing in it is carried out by friction of things about the drum wall, as well as their collision with each other during its rotation. Pressing in machines of this type occurs due to the impact on the wet things of the centrifugal force arising during the rotation of the drum at a very high speed.

Operating procedure

Manages all stages of washing built-in microprocessor in the washing machine.

• After you press the button, the machine will startwork. The electronic lock will lock the door of the hatch, the inlet solenoid valve will open and water will flow into the machine. First, water will enter the hopper with washing powder, wash it off and soap solution will flow to the tank through the rubber branch pipe. At the same time, the drum starts to rotate slowly.
• A special relay monitors the water level and stops the flow in time.
• After the required amount of water has been filled, work powerful electric heater, located in a narrow gap between the drum and the tank. When the water is heated to the set temperature, the thermal sensor will operate and the heater will switch off.
• All time allocated for washing, electric motorwill rotate the drum in reverse mode, making small breaks between individual cycles. It is impossible to say exactly how much the washing machine does. The washing time varies considerably and depends on the amount of laundry and the program you select.
• When the washing is finished, the drain pump starts to pump the dirty water into the sewer.
• Next, the rinsing process starts, which is carried out in the same way as washing.
• After the laundry is rinsed andThe waste water is drained, the spin will start. The engine will gradually unwind the drum until its rotation speed reaches several hundred rpm. Things under the action of centrifugal force will be pressed against the walls of the drum, and through the openings in it water will begin to escape from them.
• When the spinning is completed, the microprocessor will smoothly stop the engine, unlock the electronic lock and turn off the machine.

How to wash the washing machine activator type.

• The activator type machine is aa metal tank of up to thirty liters. The bottom of the tank is usually beveled at an angle, it contains a Bakelite activator, which looks like a disk with three blades. The axis on which the disk is fixed exits the tank and is connected to an electric motor fixed to the bottom of the tank. From top to tank The laundry is loaded and washing powder is poured.
• The tank is closed with a lid, a mechanical timerthe operating time is set and the motor starts to rotate the activator alternately in different directions, making small stops between the cycles - the laundry is actively mixed and washed.
• After the set time, the machine turns off.
• The spinning of things in such a machine is done manually. For this, two closely spaced rubber rollers are installed on its rear wall, the lower of which is connected to the handle. Due to the rotation of this handle, the laundry stretches between the rolls and water is squeezed out of it.
• The set and drain of water in such a machine is carried out manually through rubber hoses attached to the tap with hot water and to the edge of the bath, respectively.
