 The invention relates to household appliances and can be used to wash products.

I The purpose of the invention is to improve the quality of washing by improving the permeability of the washing solution through the thickness of the product material.

| The essence of the proposed method is that | it is the fact that simultaneously with the compression of the products, they are fed to them under overpressure.

; To implement the proposed method, the working body for washing the laundry products shown in FIG. 1-5, in FIG. 1 depicts a fundamental | seven working body; in FIG. 2 - constructive implementation of the working body; in FIG.

3 is a view A in FIG. 2; in FIG. 4 - sealed chamber cavity, cross section; in FIG. 5 is a section BB in FIG. 2.

The working body comprises a chamber assembled from segments 1, inside which there are cavities I-V. formed by flexible shells 2 and the walls of the chamber. Segments 1 with shells 2 and with each other are hermetically fastened by connections 3. Cavities I-IV are connected through the nozzles 4 and hoses 5 and 6 to the output of switches (PC) 7 and 8 controlled by electric coils 9 and 10. To other outputs PC 7 and 8 are connected with check valves 11, and the inputs of the PC are connected to the water supply system through shut-off bodies 12, check valves 13, mixer 14 and gear 15. Flexible shells 2 form

cavity V into which the articles for processing are loaded. The control electric circuit includes a command device 16, a slide 17 of which removes the voltage applied to the coils 9 and 10 when the engine slides along the tracks of the control device.

In the nozzle 4 (Fig. 4), a cylindrical nozzle 18 is installed with the possibility of adjusting its length in cavities I-IV, which determines the degree of emptying of these cavities upon contact with the shell 2 of the nozzle end face.

The cavity V contains one or more autonomous containers 19 made of an elastic material. Tanks 19 contain check valves 20, the conductivity of which is directed to cavity V. All tanks 19 are connected by lines 21 into one system with a common check valve 22 and shut-off valve 23. The tank 19 is located with the possibility of contact of its wall with adjacent shells 2.

In FIG. 5 schematically shows a cross-section of a valve 20, the slit hole 24 of which is closed by means of a spring 25.

In FIG. Figure 2 schematically shows a chamber without two segments 1 and shells 2. All segments are connected by a cover 26 with holes 27 and channels 28 for pneumatic lines 21 suitable for containers 19. A loading cover 31 is connected to the ring 29 with the hole 30. The camera has a handle 32 and is installed in a tank (not shown) with washing liquid on the supports 33.

The working body works as follows.

The products are loaded into zone V and covered with a lid 31. The organ is placed in an autonomous tank and the command apparatus 16 is set in motion. The degree of opening of the taps 12 controls the rate of filling the cavities I-IV with water.

When the engine 17 is on the track of the command device 16, the voltage is applied to the coil 10, the PC 8 is activated and the water enters the cavities II and IV, the shells 2 of which, when stretched, compress the products in zone V, displacing the liquid from them. The walls of the containers 19 are also compressed, forcing air out of them through the valves 20, which enters the products. At the same time, water is displaced from the NI cavities through the check valve И У PC 7. After squeezing the liquid from the products, the engine 17 leaves the track, PC 8 returns to its original state, under the action of the elastic forces of the shell 2 also returns to its original state, displacing water from the cavities II-IV through the PC 8. At the same time, the containers 19 also restore their shape and retract due to the elastic forces

atmospheric air through a valve 23 and a non-return valve 22. At the same time, the cavity V will be filled with liquid entering through openings 27 from the 5 ends of the chamber,

Until the control device turns on PC 7 in the same way, the products will swell, i.e. their pressed fibers will again be filled with liquid. When you turn on the pc

7, the shells 2 of the NI cavities begin to move, i.e. the pressure direction will be shifted by 90 °, water from cavities II-IV will be displaced through PC 8 and its check valve, and air will again be discharged from reservoirs 19 through valve 20. Otherwise, the process will proceed similarly.

Placement of autonomous containers 19 in the cavity of the organ V and their connection with at least two check valves

Opposite conductivity gives the effect of a periodically operating pump for supplying air from the atmosphere to the products with increasing pressure in the cavity V and for automatically preparing a new portion of air when the pressure in this cavity drops.

Placing containers 19 at the junction of adjacent shells allows additional sealing of the joints of the shells in

0 segments and to improve the outflow of fluid from the body during the compression of products, since the walls of the compressed containers serve as drainage pipes.
