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

A kind of cleaning unit of dish washer

Technical field

The present invention relates to a kind of cleaning device of dish-washing machine

Background technology

The hollow rotating shaft of existing cleaning unit of dish washer directly is connected with water pump.Such cleaning device has following shortcoming:

1, the water of the ejection of the nozzle from the spray arm is columnar water, so distribution is wide inadequately, the water that is sprayed onto above the tableware is even inadequately.

2, the water column speed of the ejection of the nozzle from the spray arm is slower, and the effect of cleaning tableware is relatively poor.

3, the rotating torque of spray arm is less, and the rotating speed of spray arm is slower.

Summary of the invention

Purpose of the present invention will provide a kind of clean result better cleaning unit of dish washer exactly, and it can overcome the deficiency of existing cleaning unit of dish washer.

In order to achieve the above object, the present invention has increased by one and has extend into the air compressor air inlet pipe that hollow rotating shaft inside extends to the hollow rotating shaft top always on the cleaning device of original dish-washing machine.The compressed air that air compressor machine extrudes enters the hollow rotating shaft top through a magnetic valve from this compressed air inlet pipe, and the water that extrudes with water pump converges.In hollow rotating shaft, produce water that a large amount of and water pump extrude bubble with pressure.These water that are being mingled with a large amount of bubbles spray from the nozzle on the spray arm, the air bubble expansion of ejection is torn into the vaporific globule of fragment with the water of ejection, and advance these vaporific globules to rush at the tableware that is cleaned, the speed of these vaporific globules, remove and to comprise the kinetic energy that hydraulic pressure that ejection is is transformed, also comprise when ejection air bubble expansion and promote the kinetic energy that the vaporific globule advances, thereby this is greater than water spray separately but the speed of the identical water column of ejection pressure.And the vaporific globule of ejection is that taper is scattered, and it is more extensive to distribute.Spray arm is subjected to spraying the reaction force of water, more is from the reaction force promotion quick rotation of the air bubble expansion generation of ejection, and the vaporific globule evenly and apace is ejected on the tableware that is cleaned, and has improved clean result.

Description of drawings:

Fig. 1 is existing cleaning unit of dish washer structural representation.

Fig. 2 is a cleaning unit of dish washer structural representation of the present invention.

The specific embodiment:

As shown in Figure 1, be existing cleaning unit of dish washer structural representation, the water that pressurizes through water pump 7 directly sprays from the nozzle on the spray arm 4 through hollow rotating shaft 5, cleans tableware.

As shown in Figure 2, be cleaning unit of dish washer structural representation of the present invention, comprise 8, one air compressor machines 9 of 7, one magnetic valves of 5, one water pumps of 4, one hollow rotating shafts of 2, one spray arms in 1, one pond of case in the dish-washing machine.Water pump 7 water inlet ends are connected with pond 2, and water pump 7 water sides are connected with hollow rotating shaft 5, and rotating spray arm 4 is housed on the hollow rotating shaft 5.Hypomere at hollow rotating shaft 5 has a compressed air inlet pipe 6 to extend into the top that hollow rotating shaft 5 inside extend to hollow rotating shaft 5.The top that why will reach hollow rotating shaft 5 is that not to be stowed under heavy cargo contracts air intake duct 6 gas outlets when other positions, and the gas of ejection produces air pocket in water pipe, causes occurring in the water pipe interruption phenomenon of a throttle body one water saving.Compressed air is provided by air compressor machine 9.The hydraulic pressure that the compressed air pressure of air compressor machine 9 outputs is greater than water pump 7 extrusion is strong, compressed air could be pressed into like this and produce bubble in the water.Otherwise the water that water pump 7 extrudes can be pressed into and damage air compressor machine in the air compressor machine 9.Will start air compressor machine 9 and then opens solenoid valve 8 earlier during startup, if be to be afraid of first opens solenoid valve 8 and the compressed air that do not have enough pressure in the tracheae, the water that water pump 7 extrudes can pour in the air compressor machine 9 and cause damage.Specific implementation method is as follows, starts air compressor machine 9 opens solenoid valve 8 more earlier, and compressed air enters compressed air inlet pipe 6 through magnetic valve 8 and arrives the discharge of hollow rotating shaft 5 tops.Start water pump 7, the hydraulic pressure in pond 2 is gone in the hollow rotating shaft 5, converge on hollow rotating shaft 5 tops and compressed air.Produce a large amount of bubbles in water, these water that are being mingled with a large amount of bubbles produce a large amount of vaporific globules from the ejection of spray arm 4 nozzles, and tapered scattering rushes at tableware, washes away tableware.Spray arm 4 is subjected to spraying the reaction force quick rotation of water and air bubble expansion simultaneously, and the vaporific globule evenly and is fast sprayed to the wash dishes tableware.
