Problems solved by technology

[0006] However, in the structure of the above-mentioned washing machine, in order to improve the strength of the bottom of the inner tub, there are more reinforcing ribs distributed on the bottom of the inner tub. The reinforcing ribs divide the outside of the bottom of the inner tub into multiple small grooves. The gap between the bottom and the bottom of the outer bucket is small. After a long time of use, the water flow is difficult to wash between the bottom of the inner and outer buckets, and the dirt accumulates more and is not easy to handle. The structure of the bottom of the inner bucket is not suitable for cleaning buckets with cleaning particles. wall function washing machine
This is because, first of all, the ribs at the bottom of the inner bucket are relatively high, and the gap with the bottom of the outer bucket is small, cleaning particles are not easy to enter between the bottom of the inner and outer bucket, and individual particles that enter with the water flow are also easy to be caught or restricted in the groove. If it does not come, the particles between the inner and outer barrels will be reduced, which will affect the normal cleaning function of the barrel wall; secondly, the cleaning particles that enter the bottom wall of the inner and outer barrels with the movement of water will form smaller grooves due to the dense distribution of reinforcement ribs. The groove is not suitable for particle movement to obtain sufficient acceleration to hit the wall of the barrel to clean the bottom wall of the barrel

Embodiment 1

[0039] Such as image 3 As shown, the groove space 7 described in this embodiment includes a large groove space 71 surrounded by external reinforcing ribs 61 and a small groove space 72 formed by dividing and forming internal reinforcing ribs 62 in the large groove space 71. The height of the ribs 61 is greater than the height of the internal reinforcing ribs 62 . This structure can make the cleaning particles move in a variety of ways in the groove space, the number of collisions is more, the cleaning effect is better, and the strength of the bottom of the inner bucket will not be reduced.

[0040] In this embodiment, the distance between the external reinforcing ribs 61 is at least 20 cm, and the height of the internal reinforcing ribs 62 is no more than 5 mm.

[0041] The inner barrel bottom 4 of the present invention is a hollow ring structure, and the hollow position 40 is provided with a particle blocking structure (refer to Figure 5 with Image 6 ).

Embodiment 2

[0043] Such as Image 6 As shown, the groove space 7 is surrounded by multiple sections of radial reinforcement ribs 63 and multiple sections of circumferential reinforcement ribs 64 , which are distributed under the annular inner barrel bottom 4 .

[0044] Since the bottom of the inner barrel is circular, the distance between two adjacent radial ribs becomes smaller as it approaches the center of the circle. In order to ensure the sufficient movement of the cleaning particles, two adjacent radial ribs 63 forming the groove space 7 are required. The angle α between them is 12°-30°, and the distance d between two radially adjacent ribs 64 in the circumferential direction is 1 / 6-1 / 2 times the radius R of the inner barrel bottom, preferably, close to the inner barrel The distance between the two circumferential reinforcing ribs 64 at the bottom hollow position 40 is the largest.

Embodiment 3

[0046] Such as figure 1 As shown, the annular inner barrel bottom 4 in this embodiment includes an arc-shaped portion 41 transitioning from the inner barrel wall and a gentle portion 42 extending toward the center, and the distance between the lower reinforcing rib 6 and the outer barrel becomes smaller radially toward the center. The area corresponding to the groove space 73 below the gentle portion 42 is greater than the area corresponding to the groove space 74 below the arc portion 41 (see figure 2 ), the height of the ribs constituting the groove space 73 below the flat portion is smaller than the height of the ribs constituting the groove space 74 below the arc portion.

Abstract

The invention discloses a washing machine inner barrel with a barrel wall self-cleaning function and a washing machine, wherein the inner barrel is coaxially arranged in an outer barrel of the washing machine, cleaning particles for cleaning the barrel wall are arranged between the inner barrel and the outer barrel, and the bottom of the inner barrel of the washing machine is externally provided with particle moving spaces for charging the cleaning particles and leading the cleaning particles to move along with water flow to obtain a moving acceleration so as to clean the wall between the bottom of the inner barrel and the bottom of the outer barrel by means of collision and friction. The particle moving spaces are a plurality of groove spaces formed by strengthening ribs outside the bottom of the inner barrel, the gaps between the strengthening ribs and the bottom of the outer barrel can lead the cleaning particles to be charged along with the water flow, and the sizes of groove spaces can lead at least five of cleaning particles to be put. The washing machine inner barrel and the washing machine disclosed by the invention are simple in structure, and the design and the distribution of the strengthening ribs are changed when the bottom of the inner barrel is injection-molded, so that the spaces for the cleaning particles to move along with the water flow between the bottom of the inner barrel and the bottom of the outer barrel exist, the material cost can not be additively increased, and the strength of the inner barrel can not be reduced.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine with the function of self-cleaning the barrel wall and its inner barrel structure. Background technique [0002] There is a closed environment between the inner and outer barrels of the existing washing machine, 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 barrel and the outer barrel Dirt will adhere to the inner wall, 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 urgent. According to the investigation of the internal environment of the washing machine ...
