Description

The invention relates to the field of commercial engineering and can be used in dishwashers.

The aim of the invention is to increase the uniformity of the supply of rinse aid due to improved mixture formation and increased reliability and ease of maintenance.

The drawing shows the proposed device.

The device comprises a water supply pipe 1, a jet pump 2 mounted on it with a nozzle 3 and a passive inlet 4, a rinse aid storage vessel 5, connected by a pipe 6 to the jet pump 2, a bypass line 7, on which jokes 8 and 9 of constant and variable cross-sections, respectively, connecting the zone 10 of the pipe ¹ for supplying water in front of the nozzle 3 of the jet 25 pump 2 with the pipe 6 for connecting the vessel 5 for storing rinsing means with the jet pump 2, while the vessel 5 for storage The rinsing agent is closed, has a nozzle 11 in the lower part for communication with the jet pump 2 through the throttle 12 and the tube 13, the upper end of which is connected to the atmosphere, and the lower end is located at the bottom of the vessel 5.

The pipe 6 for connecting the vessel 5 to the jet pump 2, the pipe 11 and the output end 14 of the bypass line 7 can be connected at one point, and the pipe 11 and the output end 14 of the bypass line 7 are located in the same horizontal plane

The device operates as follows.

Under the action of the flow of rinsing water through the pipeline 1, the jet pump 2 at the passive inlet 4 s causes a vacuum, under the influence of which the non-throttle choke 12 is sucked in, 50 rinsing agent is dispensed from the vessel 5. In the vessel 5, air penetrates through the tube 13 into the vessel.

The air pressure at the level of the lower cut of the air tube 13 always remains constant, equal to atmospheric, not depending on the liquid level above it. The rinsing agent entering through the choke 12 is mixed with the water flow through the bypass line 7 with the chokes 8 and 9 of constant and variable cross-sections and, in diluted form, is mixed with the main water stream, improving the rinsing quality.

The change in the supply of rinse aid is carried out by the degree of opening of the throttle 9, with the help of which the required vacuum is established after the throttle 12 and, therefore, the flow rate of the rinse aid.

To facilitate the adjustment of the device, the branching point of the flows through the pipeline 6, the pipe 11 and the end of the bypass line 14 should be in the plane of the throttle 12, which makes it possible to initially configure the device with the vessel 5 disconnected.

Initial ^ setup is as follows. When the vessel 5 is disconnected and the throttle 9 is completely open, the cross section of the throttle 8 t is selected in such a way that the vacuum after the throttle 12 at the nominal flow in the pipeline 1 is wound to zero or slightly lower (up to 5 MM VOD.st.).

Working adjustment is carried out only when the circuit is fully assembled by opening the throttle 9. In this case, by the number of bubbles passing per unit of time, one can judge the quantitative change in the flow of the water that is being rinsed, which day the exit point of the bubble is made in the form of an easily controlled part of the vessel, for example, transparent.

The connection of zone K) of the piping 1 for supplying vii by bypass line 7 to the piping 6 for connecting the vessel 5 to the jet pump? provides uniform t feed means due to improved mixture formation.

The exclusion of the influence of a variable level in the vessel 5 on the operation of the dispenser allows to increase its reliability.

The location of the nozzle 11 with the throttle 12 installed and the output end 14 of the bypass line 7 g of one horizontal plane creates a constant working conditions of the poser, which increases the convenience of its maintenance by providing attacks and the ability to set the mode at different values of the resistance of the rinsing showers.
