Abstract

The utility model provides a dishwasher cleaning device. Based on the existing spraying dishwasher cleaning device, a compressed air inlet pipe enters from the lower section of a hollow rotary shaft and is extended into the top of the hollow rotary shaft; air which is compressed by an air compressor enters the compressed air inlet pipe through a check valve; after reaching the top of the hollow rotary shaft, the air is exhausted from the pore of an exhaust head and converged with the water which is pressurized by a water pump, thus generating a plurality of air bubbles in water. The water mixed with a plurality of air bubbles is sprayed out from a nozzle on a spraying arm to form faster fog-shaped and dispersed beads to wash a dishware. Meanwhile, the rotation of the spraying arm is faster, which leads the fog-shaped beads which is spayed out of the nozzle of the spraying arm to wash the dishware more uniformly and improves the effect of dishware washing.

Description

A kind of cleaning unit of dish washer

Technical field

The utility model relates to a kind of cleaning unit of dish washer.

Background technology

The hollow rotating shaft of existing cleaning unit of dish washer directly is connected with water pump, and 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 on 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 spray arm velocity of rotation is slower.

The utility model content

The purpose of this utility model 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.

The utility model cleaning unit of dish washer comprises: the interior case of dish-washing machine, the pond of interior case bottom, the water pump that is connected with the pond, be connected on the water pump and reach in hollow rotating shaft in the case, be contained on the hollow shaft, rotating spray arm, put in and extend to the compressed air inlet pipe on top from the hollow rotating shaft hypomere, the compressed air inlet pipe top closure has many apertures to constitute exhaust heads and to the air compressor machine of compressed air inlet pipe air feed near the blind end.

Adopt the cleaning unit of dish washer of this structure, the compressed air that air compressor machine extrudes is discharged the water that extrudes with water pump from the exhaust head aperture on compressed air inlet pipe top and is converged.In water, produce a large amount of bubbles.The trumpet-shaped nozzle ejection of these water that are being mingled with a large amount of bubbles from the spray arm, the air bubble expansion of ejection is torn into fragment with the water of ejection, the promptly vaporific globule, and promote these vaporific globules and rush at the tableware that is cleaned.The speed of these vaporific globules is removed the kinetic energy that comprises the pressure conversion that sprays water, and the air bubble expansion that also comprises ejection promotes the kinetic energy that the vaporific globule advances, thereby the speed of the globule is greater than the speed of the water column that ejection pressure is identical separately; And tapered the scattering of spray water of ejection, it is more extensive to distribute.Spray arm is subjected to spraying the reaction force of water, more produces reaction force from the ejection air bubble expansion and promotes to rotate quickly.The vaporific globule evenly and apace is ejected on the tableware that is cleaned, has improved detersive efficiency.

The specific embodiment

Existing as shown in Figure 1 cleaning unit of dish washer comprises case 1 in the dish-washing machine, pond 2, and water pump 3, hollow rotating shaft 4, spray arm 5, the water of water pump 3 pressurizations cleans tableware through nozzle 51 ejections (shown in Figure 2) of hollow rotating shaft 4 from spray arm 5.

The utility model cleaning unit of dish washer structural representation shown in Figure 3.Comprise: case 1 in the dish-washing machine, pond 2, water pump 3, hollow rotating shaft 4, spray arm 5, compressed air inlet pipe 6, air compressor machine 7, air electric heater 8, check valve 9 each muffler 10.

The water that the pond is 2 li enters in the hollow rotating shaft 4 through water pump 3 pressurizations, arrives Xiang Duan.Add the compression air through air compressor machine 7 and enter compressed air inlet pipe 6 through check valve 9 and air electric heater 8, ejection converges with the water that water pump 3 extrudes the aperture of the jet thrust 61 (shown in Figure 4) of the compressed air inlet pipe 6 in the top of hollow rotating shaft 4, produces a large amount of bubbles in water.These are being mingled with nozzle 52 (shown in Figure 5) ejection of the water of a large amount of bubbles from spray arm 5, form the vaporific globule, rush at tableware, clean tableware.In order to prevent that the water that water pump 3 extrudes from entering air compressor machine 7, is equipped with check valve 9 in compressed air line.In order to reduce the noise that dish-washing machine produces, on the gas outlet of case 1 muffler 10 is housed in the dish-washing machine.

After dish-washing machine washes tableware,, give the air electric heater 8 energisings then as long as cut off the water pump 3, compressed air through heating sprays from the nozzle 52 on the spray arm 5 like this, simultaneously spray arm 5 rotates under the reaction force of ejection air, and the air of heat is blowed on the wet tableware that has just washed, and dries up tableware.
