Problems solved by technology

[0006] Although the above prior art realizes the spray washing function of the dishwasher to a certain extent, because the upper and lower parts of the ordinary spray arm are connected by internal welding ribs, it is easy to contact with dirt such as food residues or grease in the water during use. In places, residues are easy to fall under the impact of water flow, block the spray port, reduce the cleaning effect, and cause poor user experience and other problems

Embodiment 1

[0060] Such as Figure 1 to Figure 5 As shown, the spray device of a dishwasher in this embodiment includes a spray arm 1 arranged in the sink, communicated with the spray arm 1, and provides a water inlet pipe for the spray arm 1 to spray water. 5. The spray arm 1 described in this embodiment has a spray chamber 2 connected to the water inlet pipe 5; as the washing liquid flows into the spray chamber 2, it can ensure that the pressure value in the spray chamber 2 changes steadily Adjust component 3.

[0061] Because the washing liquid squeezes the space in the spray chamber 2, the gas overflows from the spray hole, but due to the small diameter of the spray hole, the initial stage when the washing liquid is injected into the spray chamber 2, the spray chamber The pressure in chamber 2 will increase suddenly, which will lead to misjudgment of the sensor for detecting the washing liquid in spray arm 1, which will lead to the malfunction of spray arm 1 and insufficient supply o...

Embodiment 2

[0063] Such as Figure 1 to Figure 5 As shown, this embodiment is a further limitation of the first embodiment above. The adjustment assembly 3 described in this embodiment, along with the flow of the washing liquid in the spray chamber 2, transfers the medium in the spray chamber 2 from the adjustment assembly 3 Discharge, the medium can be understood as gas or other medium that exists before the washing liquid enters the spray chamber 2, and the medium is discharged from the adjustment assembly 3, so that the pressure in the spray chamber 2 is balanced, avoiding A phenomenon in which the pressure in the spray chamber 2 increases suddenly due to the injection of the washing liquid.

[0064] Further, when the washing liquid inside the spray chamber 2 reaches a preset value or fills the entire spray chamber 2, the adjustment assembly 3 stops adjusting the pressure value in the spray chamber 2, those skilled in the art can understand that , when the washing liquid is full of th...

Embodiment 3

[0066] Such as Figure 1 to Figure 5 As shown, this embodiment is a further limitation of any one of the above-mentioned embodiment 1 or embodiment 2. The adjustment assembly 3 described in this embodiment includes being arranged on the inner wall of the spray arm 1 and communicating with the spray chamber. 2. For the first adjustment unit 301 in the inner and outer space, because the diameter of the spray hole on the spray arm 1 is mostly narrow, when the gas flows through quickly, it is often difficult to release the pressure in the spray chamber 2. Therefore, this implementation The first adjustment unit 301 described in the example makes the inside and outside of the spray chamber 2 communicate, so that the pressure in the spray chamber 2 is well balanced.

Abstract

The invention discloses a spraying device of a dish-washing machine. The spraying device comprises a spraying arm and a water inlet pipe, the water inlet pipe is communicated with the spraying arm andprovides spraying inlet water for the spraying arm; the spraying arm is provided with a first shell, a second shell and a spraying chamber which is formed by buckling a first shell and a second shell, and the first shell and the second shell are in smooth transition connection with each other; the first shell and the second shell are each composed of a connecting part comprising at least an innerlayer and an outer layer. The invention provides a spraying device of a dish-washing machine and the dish-washing machine provided with the spraying device. A butt joint rib which can be closed in abutt joint manner is arranged on the spraying arm; the strength of the spraying arm is improved, meanwhile, food residues and other dirt are prevented from falling off in the washing process and making contact with welding ribs with uneven surfaces to cause residues, a spraying opening is blocked, the cleaning effect is reduced, the inner surface and the outer surface of the spraying arm are smooth, and oil stains and the like can be effectively prevented from staying on the surfaces of the spraying arm to cause accumulation.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a spray device for a dishwasher. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and thus have higher and higher requirements for the quality, performance, humanization of use, and intelligent operation of daily necessities. Dishwashers have also entered people's lives as a convenient daily necessities. On the dishwasher, the shower is one of the key components of the dishwasher, which directly affects whether the tableware can be washed clean. [0003] At present, the water injection parts inside the dishwasher are mainly based on the spray arm structure. The spray arm is one of the important parts inside the dishwasher. It is driven by water flow to rotate and spray water to wash the tableware. The welded ribs are connected, and the welded ribs are directly exposed to th...
