Problems solved by technology

Although the existing recessed structure of the water inlet pipe can reduce the operation noise of the drainage pump to a certain extent, the noise reduction effect is poor, and once foreign objects are blocked in the water inlet pipe, it is not easy to clean. From the point of view of after-sales maintenance, there is no good experience

Embodiment 1

[0042] Such as Figure 1 to Figure 6 As shown, this embodiment introduces a washing machine drainage noise reduction structure 10. The drainage noise reduction structure 100 includes a telescopic hose 2 that can shrink and expand in the radial direction. The channel 4 and the telescopic hose 2 are in a tightened state in a free state to close the drainage channel 4 , and the telescopic hose 2 expands outward against its own elastic force to open the drainage channel 4 when the washing water flows through. During the drainage process of the washing machine, the washing water flows through the drainage noise reduction structure 100, and the telescopic hose 2 of the drainage noise reduction structure 100 expands under the action of water flow pressure to open the drainage channel 4 for the washing water to pass through; during the non-drainage process of the washing machine , the telescopic hose 2 shrinks to close the drainage channel.

[0043] In this embodiment, the telescopic...

Embodiment 2

[0047] The difference between this embodiment and the first implementation above is that: Figure 7 to Figure 8 As shown, in this embodiment, the drainage noise reduction structure 100 further includes an installation part 1 , which is fixedly connected to the inner circumference of the drain pipe 200 , and the telescopic hose 2 is fixedly installed inside the drain pipe 200 through the installation part 1 .

[0048] In this embodiment, a hollow flow channel 8 is provided inside the installation part 1, the inlet of the hollow flow channel 8 communicates with the drain pipe 200 upstream of the installation part 1, and the outlet of the hollow flow channel 8 communicates with the water inlet of the drainage channel 4. The washing water flows into the drainage channel 4 from the inlet of the hollow flow channel 8 of the installation part 1, the water outlet end of the telescopic hose 2 expands under the action of the water flow pressure, and the washing water flows out from the w...

Embodiment 3

[0054] Such as Figure 7 to Figure 8 As shown, in this embodiment, the washing machine drain pipe 200 is provided with an adapter 5 fixedly connected to the installation part 1, and the installation part 1 is fixedly connected to the inner wall of the drain pipe through the adapter 5, that is, the drainage noise reduction structure 100 The adapter piece 5 is fixedly connected to the inner wall of the drain pipe 200 to avoid displacement of the drain noise reduction structure 100 under the impact of water flow.

[0055] In this embodiment, the adapter 5 includes a circle of extension ribs 6 protruding radially along any section of the drain pipe 200, the outer circumference of the extension ribs 6 is fixedly connected with the inner wall of the drain pipe 200, and the inner circumference is provided with vertical clips. The holding rib 7, the clamping rib 7 and the inner wall of the drain pipe 200 form a clamping gap with a certain distance, the clamping gap is provided with an...

Abstract

The invention discloses a drainage and noise reduction structure of a washing machine. The drainage and noise reduction structure comprises a telescopic hose capable of contracting and expanding in the radial direction; a drainage channel allowing washing water to pass through is arranged in the telescopic hose; the telescopic hose contracts in a free state to close the drainage channel; and whenthe washing water flows through the telescopic hose, the telescopic hose expands outwards by overcoming the self-elasticity to open the drainage channel. The invention further discloses the washing machine, and the drainage and noise reduction structure of the washing machine is arranged in the washing machine. By arranging the drainage and noise reduction structure of the washing machine, in a drainage process of the washing machine, the telescopic hose can easily open the drainage channel under the action of water flow pressure, so that impact of water flow on air is relieved and the noise reduction effect of the washing machine can be achieved; and in a non-drainage state of the washing machine, the telescopic hose automatically contracts, so that bacterial mildewing caused by the factthat residual washing water in a drainage pump of the washing machine enters a washing barrel in the form of water vapor and the like is avoided.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a washing machine drainage and noise reduction structure, and also relates to a washing machine provided with the drainage noise reduction structure. Background technique [0002] With the increasing demand for laundry in the user market, there are more and more types of washing machines on the market. There are both fully automatic washing machines with pulsators and fully automatic washing machines with drums. Most of these washing machines use drainage pumps to drain water outside the body. During the external drainage process of the washing machine, the initial start-up of the drainage pump brings water flow impact, the "hush" noise caused by air impact, and the noise caused by water impact air impact in the later stage of drainage, all of which bring users a bad washing experience and even cause users to complain. . [0003] At present, the impact of th...
