Embodiment 1

[0053] Such as Figure 1 to Figure 4 As shown, in the inner barrel of a washing machine provided by the embodiment of the present invention, the necking structure 4 is an annular protrusion formed on the inner wall of the barrel body 1 by a circle of grooves pressed from the outside to the inside of the barrel body 1. The necking structure 4 has a simple structure , the entire inner tub of the washing machine does not need to be installed with other parts, and the overall manufacturing of the inner tub is simple and low in cost.

[0054] Or, the above-mentioned necking structure is obtained by an annular rib arranged along the circumference of the inner wall of the barrel (not shown in the figure), specifically by changing the thickness of the barrel body at this place or installing a circle of ribs on the barrel wall to form the Shrink structure.

[0055] Preferably, the lower end of the necking structure 4 and the inwall of the barrel body 1 are set on an inverted slope (re...

Embodiment 2

[0057] Such as figure 1 and figure 2 As shown, in this embodiment, there are two upper and lower circles of dehydration holes 5 distributed at the shrinkage structure 4. When the washing machine is centrifuged for dehydration, the inner tub rotates at a high speed, and the residual water in the clothes climbs along the inner tub wall under the action of centrifugal force. The hole 5 quickly discharges the water to improve the dehydration efficiency.

[0058] The distribution density of the upper floor's dehydration holes 51 is greater than the distribution density of the lower floor's dewatering holes 52, that is, the number of the lower floor's dewatering holes 52 is less than the number of the upper floor's dewatering holes 51 (see figure 1 ). This structure further prevents washing water from overflowing through the dehydration holes during washing and rinsing; when the washing machine is dehydrating, the lower dehydration holes are provided to avoid dehydration residues...

Embodiment 3

[0062] The difference between the present embodiment and the second embodiment is that the dehydration holes are partly or completely arranged above the necking structure and on the barrel wall below the balance ring, such as image 3 As shown, the upper dehydration holes 51 are arranged above the necking structure 4 , and the lower dehydration holes 52 are arranged on the upper half of the necking structure 4 .

Abstract

The invention discloses a washing machine inner barrel, comprising a barrel body, a balance ring mounted at the upper part of the barrel body and a barrel bottom mounted at the lower part of the barrel body, the barrel body is provided with an annular throat structure, of which the inner diameter is less than that of the barrel body, below the balance ring, multiple dehydration holes are distributed in the throat structure and/or between the throat structure and the balance ring, the lower middle part of the barrel body is of a sealing water containing structure. The inner wall, below the throat structure, of the barrel body is provided with a breakaway type filtering cover, the breakaway type filtering cover comprises a main body and a secondary block, the secondary block is arranged above the main body and below the throat structure, and is located at the upper part of the inner barrel, and a water passing gap for allowing water flow to pass through along the rotation direction of the inner barrel is arranged between the secondary block and the main body. According to the washing machine inner barrel provided by the invention, when a washing machine is used for washing clothes, washing water can be effectively prevented from overflowing from the dehydration holes by rising along the barrel wall, and the inner barrel has the characteristics of simple structure and good water saving effect.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to an inner tub of a washing machine. Background technique [0002] Existing washing machines include a washing machine with a non-porous inner tub. The entire inner tub adopts a closed water-holding design, and only a circle of dehydration holes is provided on the tub wall below the balance ring. The small holes concentrate all the washing and rinsing water in the inner bucket, making it both a washing bucket and a centrifugal dehydration bucket. The outer bucket of the washing machine is actually just a channel that collects the non-porous inner bucket and throws out water during dehydration. According to the different drainage methods, the washing machine is divided into two types: the washing machine with a drain outlet at the bottom of the inner barrel and the one with a completely sealed bottom. The washing machine with a drain outlet at the bottom of the barrel. When the inne...
