Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide a drainage and noise reduction structure of a washing machine and a washing machine. The residual washing water in the drain pump enters the drum of the washing machine in the form of water vapor, which may cause bacterial mildew, prevent the problem of bacterial growth, and provide users and after-sales personnel with the most optimized experience

Embodiment 1

[0042] like Figure 1-Figure 5 As shown, this embodiment provides a drainage and noise reduction structure for a washing machine, including an outer pipe 1 and an inner pipe 2, one end of the inner pipe 2 is fixed to the inner wall of the outer pipe 1, and the other end extends along the direction of fluid discharge; When the washing machine drains water, the outlet 3 at the extension end of the inner pipe 2 is opened, and after the drainage is completed, at least part of the inner wall of the inner pipe 2 is attached to close the outlet 3 .

[0043] The drainage noise reduction structure of this embodiment is a sleeve structure, the outer pipe 1 can be used as the drain pipe of the washing machine or be connected with the drain pipe of the washing machine, and the inner pipe 2 can be a membrane pipeline or a membrane-like pipeline. When the water in the washing machine is discharged, the large amount of water discharged will stretch the inner pipe 2, and the discharged water ...

Embodiment 2

[0070] This embodiment is a further limitation of embodiment one, and the difference between this scheme and embodiment one is:

[0071] In the drainage and noise reduction structure of this embodiment, a blocking structure (not shown in the figure) is also provided inside the outer pipe 1 . The blocking structure is hollowed out and located downstream of the inner pipe 2 along the flow direction of fluid discharge.

[0072] A hollowed-out blocking structure is set downstream of the inner pipe 2. When draining, the water flow is not blocked by the structure, and can block the relatively large water flow coming back from the countercurrent, so as to avoid excessive impact on the inner pipe 2 and avoid internal leakage. The condition that the outlet 3 of the pipe 2 is washed away by the countercurrent water flow further ensures the effect of reducing the drainage noise and avoids the problem of bacteria breeding inside the washing machine caused by the backflow of washing residua...

Embodiment 3

[0077] This embodiment is a further limitation of Embodiment 1 or Embodiment 2. The difference between this embodiment and Embodiment 1 or Embodiment 2 is:

[0078] When the washing machine drains, the water volume is large and the drainage speed is fast. The inner pipe 2 needs to be able to be stretched and then the water can be discharged. At the same time, it can be quickly attached together after being subjected to a large water flow, so as to achieve the effect of the self-sealing outlet 3, which is It is required that the inner tube 2 has a certain strength while being easy to change its state, so as not to be broken. As a preferred solution, in this embodiment, the outer peripheral wall of the inner tube 2 is provided with a reinforcing structure (not shown in the figure), which can increase the strength of the inner tube 2 and maintain the In the state of being stretched, it is not easy to be damaged, and at the same time, it can quickly self-sealing the exit 3 .

Abstract

The invention discloses a water draining noise reduction structure of a washing machine and the washing machine. The water draining noise reduction structure comprises an outer pipe and an inner pipe,one end of the inner pipe is fixed to the inner wall of the outer pipe, the other end of the inner pipe extends in the fluid draining direction, when the washing machine drains water, an outlet in the extending end of the inner pipe is opened, after water draining is finished, at least partial inner walls of the inner pipe are attached to each other, and the outlet is closed. According to the water draining noise reduction structure, the water draining noise can be greatly reduced, cleaning of blockage foreign matter is facilitated, meanwhile, the possibility that washing remaining water in awater draining pump enters a washing machine bucket in manners like water steam to cause bacteria and mildew can be reduced, the bacteria are prevented from breeding, and an optimal experience can beprovided for users, after-sales service workers and the like.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to a drainage and noise reduction structure of a washing machine and the washing machine. Background technique [0002] Along with the increase of user market laundry demand, there are more and more types of washing machines on the market. There are both pulsator fully automatic washing machines and drum fully automatic washing machines. Most of these washing machines use drain pumps to drain water out of the body. When the drainage pump is draining water to the outside of the washing machine, the initial startup of the drainage pump will cause water flow impact and air impact, which will produce a large "wheezing" noise. The user's washing experience may even cause users to complain. [0003] The existing solution to improve drainage noise is to improve the appearance and structure of the water inlet pipe to reduce the impact of the water flow in the drainage pump and ...
