Example Embodiment

[0010] Such as figure 1 As shown, it is a schematic diagram of the structure of an existing dishwasher cleaning device. The water pressurized by the water pump 7 is directly sprayed from the nozzle on the spray arm 4 through the hollow shaft 5 to clean the dishes.

[0011] Such as figure 2 Shown is a schematic structural diagram of the dishwasher cleaning device of the present invention, including a dishwasher inner box 1, a sink 2, a spray arm 4, a hollow shaft 5, a water pump 7, a solenoid valve 8, and a Air compressor 9. The inlet end of the water pump 7 is connected with the pool 2, and the outlet end of the water pump 7 is connected with a hollow shaft 5, and a rotatable spray arm 4 is installed on the hollow shaft 5. A compressed air intake pipe 6 extends into the hollow shaft 5 at the lower section of the hollow shaft 5 and extends to the top of the hollow shaft 5. The reason for reaching the top of the hollow shaft 5 is that when the air outlet of the compressed air inlet...

Abstract

The invention relates to a washing unit for dish-washing machine. The compressed water by water pump is ejected out through injection nozzle of injection arm to wash dinner service. The air inlet pipe for air compression extends to top of hollow rotation shaft through lower part of hollow rotation shaft. The compressed air enters into air inlet pipe through magnetic valve and is discharged from top of hollow rotation shaft, compressed water confluent at this place and generates a large amount of air bubble. The water mingled with air bubble is ejected out through injection nozzle and spread in fog water at faster speed to wash dinner service. The rotation of injection arm is speeded up, and the washing with fog water is more evenly. Thus the washing effect is improved.

Description

technical field [0001] The invention relates to a cleaning device for a dishwasher Background technique [0002] The hollow rotating shaft of the existing dishwasher cleaning device is directly connected with the water pump. Such a cleaning device has the following disadvantages: [0003] 1. The water sprayed from the nozzle on the spray arm is columnar water, so the distribution range is not wide enough, and the water sprayed on the tableware is not uniform enough. [0004] 2. The speed of the water column sprayed from the nozzle on the spray arm is relatively slow, and the effect of cleaning tableware is relatively poor. [0005] 3. The rotational torque of the spray arm is small, and the rotational speed of the spray arm is relatively slow. Contents of the invention [0006] The object of the present invention is to provide a dishwasher cleaning device with better washing effect, which can overcome the shortcomings of existing dishwasher cleaning devices. [0007] I...
