Problems solved by technology

[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

Embodiment 1

[0032] Such as Figure 4 As shown, in this embodiment, the flange main body 40 is provided with up and down permeable holes 5 in the area between two adjacent mounting feet 41, so that the washing machine can circulate between the inner and outer tubs of the working wash water. At the same time, the cleaning particles are prevented from entering the inner barrel through the flange 4. The flange of this embodiment is an improved design on the basis of the existing flange. The main body of the ordinary flange is extended radially outward to between two adjacent mounting feet 41 to form the flange main body of the present invention. The thickness of the extension part can be less than the thickness of the flange body, and the extension part is provided with a water-permeable hole 5 whose size is smaller than the size of the cleaning particles.

Embodiment 2

[0034] Such as Figure 5 As shown, the bottom 3 of the inner tub is provided with water permeable holes 5 that communicate up and down along the area around the opening 30. This embodiment is an improved design of the existing bottom structure of the inner tub, reducing the diameter of the opening 30 at the bottom of the inner tub, and adding a water-permeable hole 5 in the circumferential ring area.

Embodiment 3

[0036] The permeable hole 5 of the present invention is a straight long slit structure or a curved long slit structure. The long slit structure will not reduce the strength of the flange or the bottom of the inner bucket. Because most of the thread waste in the washing water is collected by the thread waste filtering structure, a small part of the thread waste is small and dispersed into thin strips. Therefore, the water permeable The hole will not cause clogging of thread chips.

[0037] A preferred solution is that the water permeable hole has a funnel structure with a reduced size from top to bottom. This structure increases the flow rate of the drain when passing through the permeable hole, which is conducive to impacting the thread chips passing through, and further reduces the possibility of blockage.

[0038] Since the center of the flange body rises, the drainage water flows in the radial direction to the edge, so the permeable holes are designed as a long slit structure d...

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 mounting structure at the bottom of the inner tub of the washing machine and a washing machine having the flange mounting structure. Background technique [0002] The inner tub and outer tub of the existing washing machine is a closed environment, and only water can pass through. Due to the limitation 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 breed are harmful to the human body. [0003] With the improvement of people's living standards and the improvement of the requirements for the quality of life, the sanitation problem of washing machines has become very urgent. The investigation of the internal environment of washing machines by...
