A flange mounting structure at the bottom of the inner tub of a washing machine and the washing machine

Abstract

The invention discloses a flange mounting structure at the bottom of an inner barrel of a washing machine and the washing machine. The washing machine has a function of cleaning barrel walls, and comprises an outer barrel and an inner barrel, wherein cleaning particles floating along with water flow are arranged between the outer barrel and the inner barrel to clean the barrel walls, and a flange capable of preventing the cleaning particles from entering the inner barrel from the bottom is arranged at the bottom of the inner barrel. The flange comprises a main body and mounting legs which are distributed around the main body and are fixed on the inner barrel; an area in the center of the bottom of the inner barrel corresponding to the main body of the flange is an up-down through opening; the diameter of the main body of the flange is more than or equal to the inner diameter of the opening, or is smaller than the inner diameter of the opening; and the size of a gap between the outer edge of the main body of the flange and the inner edge of the opening meets the requirement of preventing the cleaning particles from entering the inner barrel from the gap. The flange mounting structure is simple in structure and low in cost, can prevent the cleaning particles between the inner barrel and the outer barrel from entering the inner barrel, and achieves an effect of preventing the cleaning of the barrel walls from being influenced due to the decrease of the cleaning particles.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a flange installation structure at the bottom of an inner tub of the washing machine and a washing machine with the flange installation structure. Background technique [0002] There is a closed environment between the inner tub and the outer tub 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 tub and the outer tub 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] With the improvement of people's living standards and the improvement of the quality of life requirements, it is very urgent to solve the hygiene problem of washing machines. According to the investigation of the interna...

[0006] However, in the structure of the inner tub bottom of the above-mentioned existing pulsator washing machine, the flange 2' is fixed to the inner tub bottom 1' through the mounting feet 22', and the central opening area 4' of the inner tub bottom 1' is installed coaxially with the flange main body 21'. A large water-permeable gap 3' is reserved, that is, the diameter d' of the flange main body 21' is smaller than the inner diameter D' of the central opening area 4' of the bottom of the inner barrel 1' (see figure 1 and figure 2 ), the water-permeable gap 3' can allow the wash water to circulate between the inner and outer tubs, but it can also allow the soft particles between the inner and outer tubs to enter the inner tub, thereby reducing the number of soft particles between the inner and outer tubs, which affects cleaning The effect of inner and outer barrel walls
