Abstract

The invention relates to household appliances, in particular, to washing machines and improves the quality of washing by intensifying the mixing of the washing solution. The housing 1 of the machine is provided with a horizontal partition 12, on which a perforated tank 4 with activators 7 and their rotation drive is mounted, as well as means 14 for input and output of the central gear wheel 9 from engagement with gears 8 activators 7. When washing tank 4. the drive shaft 3 pulls the gear 8 into rotation. They run around the gear wheel 9 and thereby cause the activators 7 to rotate. When spinning, the gear wheel 9 is attracted by the electromagnet 14 to the horizontal partition 12 of the housing 1 and the drum 4 operates as to centrifuge at a higher rotational speed. 2 Il.

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

The purpose of the invention is to improve the quality of washing by intensifying the mixing of the washing solution. Figure 1 shows the kinematic scheme of the proposed machine (in the washing mode); not figure 2 - the same. in spin mode.

The machine contains a rotary shaft 3 perforated along the entire height mounted on the cylindrical case 1 rotatably on a vertical shaft 3 installed in the support 2, the lower part of which has the shape of an inverted truncated cone. The drum rotation drive in the washing and spinning modes has a single two-speed electric motor 5, which, through a V-belt transmission 6, transmits the rotation to the drum 4. At the bottom of the drum on its conical surface

activators 7, uniformly circumferential around the circumference, are mounted, at the ends of the shafts of which there are fixed bevel gears 8 which engage with a non-driven conical central gear wheel 9. The gear wheel 9 has the ability to move vertically along the shaft 3, which acts as a guide for this movement, fixed to the inner wall of the tank by means of the elastic corrugated diaphragm 10 and is supported through the elastic element 11 on the horizontal partition 12.

The corrugated diaphragm 10 is designed to tightly separate the two cavities of the tank — the bottom, in which the drum drive is located, and the top, filled with cleaning solution. In addition, the elastic corrugations of the diaphragm allow

make vertical movements of the gear wheel 9 associated with it.

The horizontal partition 12 is a power element and serves to mount parts and assemblies of the drum drive and the non-drive gear moving mechanism on it.

Constant gearing of gears 8 and wheels 9 and the required clearance in engagement are provided by pressing wheel 9 by element 11 to three adjustable stops 13. Disengagement of gears engagement is performed by means of an electromagnet 14, which engages the core 15 and disconnects it from rigidly connected to it non-driving wheel 9 (figure 2).

The machine works as follows

Ode is poured into the upper cavity of the housing 1 and detergent is added. The machined products are inserted into the perforated drum 4 and the electric motor 5 is turned on. The rotational movement from the electric motor is transmitted through a V-belt transmission on the shaft 3 and on the drum 4 fixed to it with two bevel gears 8, which roll around the drive gear and rotate the fixed gears. with them on one shaft activators 7. Thus, activators make a complex movement: around their axis A and at the same time around axis B - rotation of the perforated drum. This causes the articles to move in a swirling detergent solution along a complex trajectory. The complex hydromechanical effect on erasable products reached with the fact that during the rotation of the drum, the product under the action of centrifugal force tends to press against its walls, but this is prevented by axial and radial hydraulic currents created by inclined activators, the points of which have opposite directions of movement.

All this in combination with the free circulation of the washing solution through the perforations of the drum intensifies the washing process.

For squeezing, the linen is drained from the tank through the drain nozzle, include

an electromagnet 14. which, overcoming the force of the spring {element 11), engages the core 15 and disengages the central gear wheel 9 connected to it 9. With the switch of the poles the electric motor 5 switches to the speed at which the spinning occurs.

Using the proposed machine allows to intensify the washing process and thus improve the quality

washing the laundry, as well as eliminate the need for an additional electric motor to drive the drum in the spin mode.
