Description

(54) HOUSEHOLD WASHING MACHINE

The base 8 and the housing cover 10 are made of molded plastic.

The drive shaft 7 is installed vertically inside the chamber / and is provided with a surrounding protective tube 13 located between the impeller body and the lid 2 of the chamber /.

In the bottom 4 of the chamber 1 there is a recess 14. in which the filter 15 is mounted. To prevent the filter from being lifted when the chamber is filled with liquid, there is a grating 16 held in the lug 17 of the lid {8, as well as one or more gratings which are additionally installed (not shown) . When cleaning the filter 15. lattice 16 can be easily removed and then put back. The hole 19 in the filter housing 15 serves to drain the filtrate.

A housing 20 is movably mounted on the body of the impeller 6 with a float 21 for controlling the shaft 22 located outside the machine and connected to the motor starting contactor (not shown) at a predetermined level of washing liquid in the chamber.

The float 21 is fixed on the axis 23 with the possibility of oscillatory movement, and the axis has a bend 24 which interacts with the protrusion 25.

In the chamber / mounted pipe 26 with a shutter 27 for draining the liquid. The shutter 27 is installed with the possibility of reciprocating movement along the axis of the nozzle using the handle 28 and the eccentric 29 and serves to close and open the outlet of the nozzle 26 connected to the nozzle 30 to remove fluid from the machine.

Being in the lower position, the shutter 27 closes the outlet opening of the nozzle 26, hermetically rests against the U-shaped gasket 31, thereby ensuring the drainage of excess liquid, while the level of the latter in the chamber / cannot exceed the height of the nozzle 26.

When installing the pipe 26 with the bolt 27 in the back of the machine, it is controlled automatically by an electromagnet and shaft located outside the chamber (not shown), and when the pipe 26 is installed in the front of the machine, it is also driven by a lever driven from the electromagnet drawings not shown).

The chamber 1 is equipped with two hinged doors 32, with the deflector 33 fixed on the inner door below, which serves to direct the flow of fluid along the inner surfaces of the doors to the bottom 4 of the chamber.

Dishwasher Maschina works in a natural way.

The machine is loaded with detergent, after which the handle 27 closes the shutter 27 of the nozzle 26 and supplies hot water from the water supply system through

the tap and the hose connected to it (not shown in the drawings), wherein the hose is connected to the device 3 for supplying water.

When the water reaches a predetermined level, the float 2} turns on the electric motor (not shown in the drawings) and carries out the washing of dishes for approximately 6 minutes. The motor is then turned off, after which the shutter 27 of the nozzle 26 is opened using the handle 28 and water from the chamber / through the nozzle 30 is removed.

Next, the shutter 27 of the nozzle 26 is again lowered, hot water is supplied and the dishes are rinsed for 3 minutes by disconnecting the pre-flow of fresh water. The machine is then stopped and the water after rinsing is removed by lifting the stopper of the nozzle 26 and the nozzle 30. Rinsing is repeated in hot water for better subsequent drying of the dishes. Next, from the filter 15 are removed possible contaminants left from the dishwashing.

The machine can also operate fully in automatic mode, with the nozzle 26 with the discharge gate 27 being located at the rear of the machine.

Domestic dishwasher but compared to the known is simple in its design, has small dimensions and is easy to maintain. All the main parts of the machine are made of molded plastic and can be easily disassembled and assembled, and the machine can be easily installed in a given place.

Claims (3)
