Description

 The invention relates to household appliances, in particular to washing machines used at home.

 A washing machine is known, comprising a laundry tub installed in the housing with an activator located therein in the form of a blade disk connected to a drive for its rotation, and a removable means for mechanically acting on laundry, consisting of a holder and a horizontal disk connected by elastic suspensions, located under the lid, which matches the shape of the tank.

 The practice of operating prototypes of similar washing machines has shown that washing clothes from dense fabrics requires more time than washing clothes from thin fabrics.

 The technical result achieved in this invention is to reduce the time for washing clothes from dense fabrics while maintaining the quality of washing.

 The specified technical result is achieved in that in a washing machine containing a laundry tub with an activator in the form of a drive blade disk and a removable means for mechanically acting on the laundry, consisting of a holder connected by elastic suspensions and a horizontal disk, the contour of which corresponds to the shape of the tank, according to the invention, the disk has bristles made of synthetic material facing the bottom of the tank, the softening temperature of which is not lower than the boiling point of water, while the tufts of brushes us arranged to form discontinuous bands, repeating drive circuit.

In FIG. 1 shows a washing machine, FIG. 2, view A in FIG. 1 (surface of a horizontal disk facing toward the bottom of the tank), in FIG. 3
section BB in FIG. 2, in FIG. 4 an arrangement of bristle tufts.

 The washing machine contains a tank 2 installed in the housing 1 with a cover 3. In the tank 2 there is a blade disk 4 connected by a gear 5 to an electric motor 6. Under the cover 3 there is a removable tool for mechanically acting on the laundry, consisting of a holder 7 and a horizontal disk 8 made with a flange around the perimeter and connected to the holder 7 by elastic suspensions 9. On the surface 10 facing the bottom of the tank 2, the horizontal disk 8 has bristles 11. Depending on the contour of the disk and the shape of the tank, the beams can be placed to form intermittent straight stripes 12 or concentric rings 13.

 The washing machine operates as follows.

 The cover 3 is removed from the tank 2. Temporarily remove the removable means for mechanical impact on the laundry. Tank 2 is filled with washing solution just below the level gauge (not shown). A portion of laundry, for example, made of dense cotton fabric, is placed in the solution. A removable means for mechanical action is placed in the tank 2. At the same time, the horizontal disk 8 imbues laundry that is above the surface of the solution into the solution. The lid 3 of the tank 2 can not be closed, as the holder 7 will protect the solution from spraying. An electric motor 6 is turned on, which through the transmission 5 starts to rotate the blade disk 4. The rotating blade disk drives the washing solution. The resulting fluid flows carry the laundry along. Moving, the laundry rubs against the walls of the tank 2, as well as the bristles 11, the bundles of which are fixed on the surface 10 of the horizontal disk 8.

 When the laundry comes into contact with the bristles, the washing process is significantly activated. Additionally, the ends of the bristles have the ability to penetrate into the folds and seams of the laundry, contributing to better washing. A positive influence on this is exerted by the oscillatory movement of the horizontal disk 8 itself on the elastic suspensions 9.

Due to the fact that the washing takes place in a washing solution having a temperature of 60 80 ^° , the bristles should not soften and should not have any permanent deformation upon mechanical action of the laundry.

 After the set time has elapsed, washing stops. The electric motor 6 is de-energized, the blade disk 4 is stopped.

 A removable means for mechanically affecting the laundry, consisting of a holder 7, a horizontal disk 8 and suspensions 9, is removed from the tank 2. The washed laundry is passed through a squeezing device (not shown). The empty tank 2 is loaded with the next portion of linen.

 The presence of a bristle coating on the surface of the horizontal disk allows for high-quality washing in a shorter time.

Claims (1)

 A washing machine comprising a laundry tub installed in the housing and closed by a lid with an activator located therein in the form of a blade disk connected to a drive of its rotation, and a removable means for mechanically acting on laundry, located under the lid, consisting of a holder and a horizontal disk connected by elastic suspensions the contour of which corresponds to the shape of the tank, characterized in that the horizontal disk has beams of bristles made of synthetic material fixed on the surface facing the bottom of the tank oal, the softening temperature of which is not lower than the boiling point of water, while the bristle tufts are located with the formation of discontinuous strips repeating the contour of the disk.
