Problems solved by technology

However, in order to ensure the flow rate and pressure of the sprayed water column, only a limited number of spray holes can be opened on each spray arm body in the dishwasher, so that the area covered by the spray of a single spray arm body is also limited, which affects the overall cleaning effect
Moreover, in order to ensure the cleaning effect, the current general situation is to use a sufficiently long washing time, which will reduce the washing efficiency of the dishwasher, thereby causing a bad user experience for the user

Embodiment A

[0069] combine Figure 1 to Figure 7 , the spray arm assembly 100 includes a first spray arm body 1 and a second spray arm body 2, and the two spray arm bodies are structurally separated and independent from each other.

[0070] The first spray arm body 1 and the second spray arm body 2 are assembled into a lower spray arm assembly, which is used in a dishwasher as a whole. The first spray arm body 1 and the second spray arm body 2 are provided with a form-fit matching structure, and the first spray arm body 1 and the second spray arm body 2 can perform limited relative rotation.

[0071] The first spray arm body 1 or the second spray arm body 2 can be used in the dishwasher as a separate spray arm body. At this time, the first spray arm body 1 or the second spray arm body 2 is an independent component. There is no direct relationship between them.

[0072] The spray arm assembly composed of the first spray arm body 1 or the second spray arm body 2 can perform a horizontal r...

Embodiment B

[0095] Figure 8 , Figure 9 , Figure 10 Another embodiment provided by the present invention is embodiment B. Specifically, it includes the first spray arm body 1 and the second spray arm body 2, and the two spray arm bodies are structurally separated and independent from each other.

[0096] The first spray arm body 1 and the second spray arm body 2 are assembled into a lower spray arm assembly, which is used in a dishwasher as a whole. And there is no relative movement between the first spray arm body 1 and the second spray arm body 2, that is, the limited angle is zero degrees.

[0097] The spray arm assembly formed by the first spray arm body 1 and the second spray arm body 2 has only one overall shape, and the spray arm assembly has multiple movement modes under the overall shape.

[0098] The first spray arm body 1 and the second spray arm body 2 are assembled into a spray arm assembly, and the first spray arm body 1 and the second spray arm body 2 constitute two f...

Abstract

The invention discloses a spraying arm assembly. The spraying arm assembly comprises first spraying arm bodies and second spraying arm bodies. First cavities are formed inside the first spraying arm bodies, and first spraying holes communicated with the first cavities are formed in the first spraying arm bodies. The second spraying arm bodies are arranged on the first spraying arm bodies, the second spraying arm bodies and the first spraying arm bodies share the same rotating shaft, second cavities are formed inside the second spraying arm bodies, and second spraying holes communicated with the second cavities are formed in the second spraying arm bodies. According to the embodiment of the spraying arm assembly, the first spraying arm bodies and the second spraying arm bodies are arranged coaxially, in this way, the spraying arm assembly has several different operation modes, the working modes of the spraying arm assembly can be selected according to actual requirements, and selections of users are increased.

Description

technical field [0001] The invention relates to the technical field of washing appliances, in particular to a spray arm assembly. Background technique [0002] Household dishwashers can replace manual cleaning of tableware. It usually sprays washing water to the tableware through the rotating spray arm body, combined with the effects of water reflection, splashing and flowing, etc., to achieve covering and cleaning of all tableware in the dishwasher. However, in order to ensure the flow rate and pressure of the sprayed water column, only a limited number of spray holes can be opened on each spray arm body in the dishwasher, so that the area covered by the spray of a single spray arm body is also limited, which affects the overall cleaning effect. Moreover, in order to ensure the cleaning effect, the current general situation is to use a sufficiently long washing time, which will reduce the washing efficiency of the dishwasher, thereby causing a bad user experience for the us...
