Description

ё

The invention relates to household appliances.

A household dishwasher is known which comprises a washing chamber with a shower device installed therein, a washing solution bath with a filter and a drain pipe, a circulation pump, a water supply pipe, a level sensor installed in the washing bath.

The disadvantage of this design is the complexity of the control circuit, the need for multiple water changes to eliminate residues of detergents on the surface of the dishes.

The aim of the invention is to improve the quality of washing, reduce water consumption, simplify the design.

This goal is achieved by the fact that in a machine consisting of a washing chamber with a shower device installed in it, a bath for a washing solution with a filter and a drain pipe, a circulation pump, a water supply pipe installed in the washing bath of the level sensor, and a water supply pipe a flow regulator connected to the level sensor is installed, configured to supply water with a flow rate less than the flow rate of the drain, the drain pipe is made in the form of a P- knee installed in the bath for washing solution braznoy shaped intake end of which is placed at the bottom of the bath, and an outlet end withdrawn beyond below the intake, wherein the level sensor is installed below the knee spout.

The drawing shows the proposed dishwasher.

The household dishwasher contains a washing chamber 1, a bath 2 for washing solution installed in it, and a shower 4

fixture 3, drain pipe 4, circulation pump 5, water supply pipe 6 with holes.

A level sensor 7 and a filter 8 are installed in the washing bath 2.

A flow regulator 9 connected to the level sensor 7 is installed on the water supply conduit 6, and is configured to supply water with a flow rate less than the discharge water flow rate.

The drain pipe 4 is made in the form of a U-shaped knee installed in the bath 2 for the washing solution, the intake end 10 of which is placed at the bottom made with a recess, the bath 2, and the output end 11 is brought out beyond its lower end 10, when this level sensor 7 is installed below the knee of the drain pipe 4,

A dish cassette 12 is positioned above the scent device 3.

The machine operates as follows.

When the machine is turned on in the flow controller 9, the valve opens and water flows through the holes in the water supply pipe b into the washing chamber 1 on the dishwasher cartridge 12. When the bath 2 is filled to a certain level, a level sensor 7 is activated, giving a command to turn off the water supply through the flow controller 9 and to turn on the circulation pump 5, which draws water through the filter 8 and delivers it to the choking device 3.

When the pump 5 is turned on, part of the water fills the pipelines, chokes the fitting 3, freezes in the space of the washing chamber 1, flows down the dishes, i.e. the level in the bath 2 decreases, which leads to the actuation of the level sensor 7, the inclusion of the controller 9 and the additional supply of water to the bath 2 until the level sensor 7 is turned off. The water level will be below the knee of the drain pipe 4 with the pump 5 running.

I. After the washing time (pump operation) has elapsed, the pump stops 5. a level sensor washing bath, characterized in that, for the purpose of

This leads to additional water entering the bath 2, the level of the latter in the bath rises above the knee of the drain pipe 4, which is choked, and the water is drained from it from the bath 2. Upon lowering the level and turning on the sensor 7, the regulator 9 is turned on again for filling . Fresh water at the same time through the holes of the pipeline 6 enters the dishes, partially rinsing it, and rinses the chamber. Since, as a result of the limiting effect of the controller 9, more water is drained than it enters the bath, the joint process of draining and filling does not last long, and when the water level reaches the lower cut of the drain pipe 4 in the bath, air enters it and the draining process stops.

According to the control algorithm, the washing process can be completed at this stage or continued, the water replenishes the bath until the level sensor triggers and everything repeats again.

Each stage of washing is carried out with a minimum number of commands, while ensuring all necessary operations for high-quality washing: operation of the pump (at the same time as the pump, heating of the bath water can be switched on as necessary), draining water, rinsing dishes and bathtubs, filling the bathtub with clean water ,

In this case, the machine has only one pump for circulating the washing solution, there is no pump for pumping water, and the complete removal of the spent solution from the bath and the reduction in the content of detergent residues is ensured by more complete removal of water from the bath and the intermediate combination of draining and filling operations. The drain pump, when used, leaves a fluid volume equal to its capacity and the capacity of switching pipelines when draining.

to improve the quality of washing, reduce water consumption, simplify the design, a flow regulator connected to the level sensor is installed on the water supply pipe, configured to supply with a flow rate less than the flow rate of the water in the drain, the drain pipe is made in the form of a U-shaped knee washing solution, intake

the end of which is located at the bottom of the bathtub, as well as the intake, while the level sensor of the output end is brought out beyond its limits below the knee of the drain pipe.
