Problems solved by technology

[0006] Although the above-mentioned prior art obtains the precise rotation speed of the spray arm through the magnetic sensitive switch to a certain extent, thereby avoiding the generation of errors and ensuring the air pressure in the waterway by setting an exhaust structure in the waterway, none of them solves the problem of the present application. When the spray arm is filled with water, because the spray hole on the spray arm is too small, when the washing liquid flows in the spray arm, the air in the spray arm passes through the spray hole at high speed, causing the internal air resistance to increase sharply, which in turn leads to The sensor that detects the amount of water injected misjudged the rotational power of the motor

Embodiment 1

[0070] like 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.

[0071] 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 of w...

Embodiment 2

[0073] like 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.

[0074] 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 the s...

Embodiment 3

[0076] like 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 an adjusting assembly, the spraying arm is provided with a spraying chamber; the adjusting assembly is arranged on the inner wall of the spraying arm to form a part of the spraying chamber, and an included angle is formed between the adjusting assembly and the flowing direction ofthe washing liquid in the spraying chamber; and the adjusting assembly is configured to discharge the medium in the spraying chamber from the adjusting assembly by utilizing the acting force of the washing liquid entering the spraying chamber. The invention provides a spraying device of a dish-washing machine. At the initial stage of water injection in the spraying arm, the air in the spraying armcan be quickly discharged without resistance; the influence of the inside of an original spraying arm on the water injection sensor is eliminated, a certain included angle is formed between the adjusting assembly and the flowing direction of washing liquid in the spraying cavity, it is effectively guaranteed that the adjusting assembly is kept closed under the dual effects of the buoyancy and theimpact force of the washing liquid in the working process of the spraying arm, and normal work of the spraying arm can be guaranteed.

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 jetting part inside the dishwasher is mainly based on the spray arm structure, and the spray arm is one of the important parts inside the dishwasher, which is driven by water flow to rotate in a directional way to spray water to wash the tableware. At the beginning of the dishwasher filling the spray a...
