Abstract

The utility model discloses an inner tub of a washing machine, and the size and the distribution of holes on the inner tub of the washing machine are improved. The holes distributed at the middle lower part of the tub wall of the inner tub of the washing machine are smaller than the holes of the upper part, the diameter of each hole of the middle lower part is between 2.5 mm and 3.5 mm, and the diameter of each upper part hole is 1.5-2.5 times of the diameter of each lower part hole. The utility model has the advantages that the water level of the inner tub can be raised, and the water can be saved; when the utility model is used for dewatering, the water of the inner tub can be discharged, the waterfall effect can be formed easily, and the cleaning degree can be improved.

Description

washing machine tub

The utility model relates to an inner barrel body of a washing machine in which the size and distribution of holes on the barrel wall are changed, in particular to an inner barrel of a washing machine.

The dehydration holes on the inner barrel of the existing washing machine have the same size and the same distribution density, and such an inner barrel is not easy to generate a waterfall-like water flow.

The purpose of the utility model is to overcome the shortcomings of the prior art, and propose a washing machine inner tub with improved structure, so that the internal water flow can easily generate a waterfall-like water flow, increase the washing power, and can improve the cleaning ratio of clothes.

The utility model purpose is achieved by the following technical solutions:

The inner barrel of the washing machine includes a circular washing machine inner barrel wall and a circular washing machine inner barrel bottom, and is characterized in that the holes distributed in the middle and lower parts of the washing machine inner barrel wall are smaller than the holes in the upper part, and the diameter of the middle and lower holes is 2.5~ 3.5 mm, the holes distributed in the upper part have a diameter of 1.5 to 2.5 times that of the lower part.

The middle and lower part of the inner tub of the washing machine refers to the position from the bottom of the inner tub of the washing machine to below 2/3 to 3/4 of the height. The distribution of the middle and lower holes is denser than that of the upper holes, the longitudinal spacing of the middle and lower holes is 12-14 mm, and the longitudinal spacing of the upper holes is 15-17 mm.

The utility model has the advantages that: because the dehydration holes in the middle and lower parts are small, the distribution is also relatively dense, and the small holes are conducive to keeping the ribs at the bottom of the pulsator rotating and pumping water from the outer barrel to the inner barrel to raise the water level of the inner barrel, which can save water; the distribution of the holes It is denser, which is conducive to dehydration. The water is discharged to the outer bucket to enhance the dehydration effect. The upper hole is larger, and the ribs at the bottom of the pulsator rotate. The water pumped into the inner bucket from the outer bucket can quickly return to the outer bucket, which is conducive to water circulation. ;The distribution of holes is relatively sparse, which is conducive to improving the strength of the inner barrel, and offsets the adverse effect on the strength of the inner barrel due to the increase of the dehydration aperture. This structure is conducive to the formation of "waterfall" water flow. When the water level is low, the water level of the inner bucket can be raised; although the water level difference between the inner and outer buckets is large, the lower nozzle has a small flow of water and a small pressure loss, which can still form a better "waterfall" "Waterfall" effect, when the water level is high, the flow of water flow is long, and the pressure loss is also large. At this time, the water level difference between the inner and outer buckets is low, which reduces the resistance and greatly enhances the "waterfall" effect.

An embodiment is illustrated in conjunction with the accompanying drawings:

Figure 1 is an expanded view of the inner tub of a washing machine,

The hole diameter in the middle and lower part of the barrel body is small, with a diameter of 3 mm, and the vertical center distance of the holes is 13 mm. The center distance is slightly larger. The circumferential spacing of these holes is the same, both are 21 mm, and the arrangement is neat and beautiful.

Claims (3)
