Problems solved by technology

[0007] However, the structure of the above-mentioned washing machine has the following defects: if the flexible particles are always placed between the inner and outer tubs, they will collide with the walls of the inner and outer tubs during the dehydration process of the washing machine to generate relatively loud noises, which will also damage the particles and reduce the number of particles to affect the cleaning effect; Cleaning particles are discharged, the above structure is difficult to completely discharge, and there are still residual particles during dehydration; in addition, due to the small gap between the bottom of the inner bucket and the bottom of the outer bucket, it is difficult for water to wash between the bottom of the inner and outer buckets after long-term use. Dirt accumulates a lot and is not easy to deal with. The cleaning particles with the above structure cannot realize the self-cleaning of the bottom area of ​​the inner bucket

Embodiment 1

[0040] Such as figure 2 and image 3 As shown, in the present embodiment, the improvement of the bottom of the outer bucket is specifically: the surface of the bottom of the outer bucket is inclined from the center 8 of the bottom of the outer bucket radially toward the side wall 9 of the outer bucket. There is a surface inclined area 7, which is set along the circumferential direction, and the height near the center 8 of the outer tub is higher than the height near the side wall 9 of the outer tub, and the washing machine drain 6 is located at the lowest point at the bottom of the outer tub. This structure is good for drainage, especially when the amount of water in the later stage of drainage is small, the drainage water will wash the cleaning particles into the drainage outlet.

[0041] The surface inclined area 7 is a structure that gradually decreases from the center 8 of the outer barrel bottom to the edge. Specifically, the height of the inner surface of the outer bar...

Embodiment 2

[0044] Such as figure 2 and Figure 4 As shown, in this embodiment, the improvement of the bottom of the outer bucket is specifically: an inclined and gradually lower structure 11 along the circumferential direction consistent with the dehydration rotation direction of the inner bucket, and the height of the inner surface of the bottom of the outer bucket 5 gradually decreases clockwise or counterclockwise along the circumferential direction, The gradually lowering direction is consistent with the rotation direction of the inner tub of the washing machine when dehydrating. Generally, the dehydration rotation direction of the inner barrel of the existing washing machine is clockwise, so the height of the inner surface of the outer barrel bottom 5 gradually decreases clockwise (see figure 2 ), the drain port 6 is located at the lowest point 14 at the bottom of the outer barrel, and one side is adjacent to the highest point 15. This structure is not only conducive to the disc...

Embodiment 3

[0047] This embodiment is a combination of Embodiment 1 and Embodiment 2. The change of the height of the inner surface of the bottom of the outer bucket is: while gradually decreasing from the center radially outward, it also gradually decreases along the circumferential direction. This structure is more conducive to drainage. The cleaning particles are discharged into the drain with the water flow.

[0048] The above-mentioned embodiments have the inner surface of the bottom of the outer bucket with an inclined structure, and the potential energy brought by the slope height difference is converted into flow energy of water, so as to increase the impact force of the water flow and prevent cleaning particles from remaining on the inner surface of the bottom of the outer bucket.

Abstract

The invention discloses a self-cleaning washing machine. The self-cleaning washing machine comprises an inner bucket and an outer bucket, wherein cleaning particles rotating along with water current to clean the inner wall of the outer bucket and the outer wall of the inner bucket are arranged in a cavity between the inner bucket and the outer bucket; inside the outer bucket, an indent annular water channel is formed along the circumferential direction at the bottom of the outer bucket adjacent to the side wall of the outer bucket; a water outlet is communicated with the annular water channel; the depth of the annular water channel decreases clockwise or anticlockwise along the circumferential direction, and the decrease direction is relevant to the rotating direction during dehydration of the inner bucket of the washing machine; the water outlet is formed in the lowermost position of the annular water channel, and one side of the water outlet is adjacent to the shallowest part of the annular water channel. Through the improved structure of the bottom of the outer bucket, the discharge of the cleaning particles is facilitated; particularly before the end of drainage and during dehydration, the cleaning particles tend to be left at the bottom of the outer bucket due to the flat structure of the bottom of the conventional outer bucket; by adopting the structure of the self-cleaning washing machine, the flow speed and erosion force of water current are increased, and the cleaning particles can be discharged completely.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a self-cleaning washing machine in which cleaning particles are arranged between inner and outer tubs to automatically clean the tub walls between the inner and outer tubs as the water flows. Background technique [0002] The existing pulsator washing machine is a closed environment between the inner and outer tubs, and only water can pass through. Due to the limitations of the above-mentioned structure of the washing machine and the particularity of the use environment, after 3-5 months of use, the outer wall of the inner tub and the Dirt will adhere to the inner wall of the outer barrel, thereby breeding different degrees of bacteria, and most of the bacteria that grow are harmful to the human body. [0003] Along with the raising of people's living standard and the raising of the quality of life requirement, the solution of the hygienic problem of washing machine has shown very...
