Abstract

The utility model provides a dewatering drum of a fully-automatic washing machine, which is in the shape of a cylinder. A helical rib body is arranged on the surface of the inside wall of the dewatering drum; water outlet holes are arranged on the top of the helical rib body which is adjacent to the upper end of the dewatering drum. The dewatering drum has the advantages of simple manufacturing process, improvemento of production efficiency and low cost.

Description

The automatic washing machine dehydration barrel

Technical field

The utility model relates to a kind of washing machine, especially relates to the automatic washing machine dehydration barrel.

Background technology

In the known technology, the automatic washing machine dehydration barrel mostly is porose dehydration staving, and this porose dehydration barrel has two types: all-plastic dehydration barrel and stainless steel dewatering tub, and wherein all-plastic dehydration staving is connected with screw with gimbal, forms water containing chamber; Stainless steel dewatering tub connects to form water containing chamber by collet, dehydration staving, gimbal with screw.This porose dehydration barrel, when washing steel ladle and dehydration barrel between have an appointment about 20% water do not participate in washing, cause the waste of water.For using water wisely, the atresia dehydration barrel has appearred, existing atresia dehydration staving is up big and down small bullet, the cone generatrices gradient is 1～2 °, when dehydration barrel is rotated, water in the clothing arrives the dehydration barrel sidewall because of action of centrifugal force, because sidewall is the inclined-plane, water can be thrown out of outside the bucket along inclined-plane climbing to the staving top end face again, but in order to make the angle of sides of bucket, bucket is whole must make up big and down small taper, make for the panel beating of staving like this and bring difficulty, and the following collet that is attached thereto is the corrosion resistant plate drawn component, both rivet the back and form water containing chamber, manufacturing technique is difficulty relatively, and both are metalwork, and cost is higher.

Summary of the invention

Problem to be solved in the utility model be at existing atresia dehydration barrel provide that a kind of cost is lower, the comparatively simple atresia dehydration barrel of manufacture craft.

The technical scheme in the invention for solving the above technical problem is: a kind of automatic washing machine dehydration barrel, its integral body is cylindrical, on the dehydration barrel madial wall, be pressed with helical form muscle body, near helical form muscle body top, be provided with apopore near this dehydration barrel upper end.

Compare with existing atresia dehydration barrel, advantage of the present utility model is:

(1) equal and opposite in direction about the dehydration staving diameter can reduce the staving manufacture difficulty greatly, saves plate.

(2) helical form muscle body water that clothing is thrown away rises to apopore and breaks away from clothing along helicoid, has improved dehydration rate, can strengthen staving self intensity again.

(3) adopt this columnar dehydration barrel, its collet can be working of plastics, and staving can adopt screw to be connected with collet, and connected mode is simple, increases work efficiency in batch process easily.

(4) plastic bottom Toby metal bottom bracket cost is cheaper.

Fig. 2 is a helical form muscle body structure schematic diagram on the dehydration barrel inwall;

Fig. 3 is that helical form muscle body normal direction cutting plane is shaped as the triangular structure schematic diagram;

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.

Referring to accompanying drawing 1, the dehydration barrel 1 of present embodiment is the cylindrical shape of equal diameters up and down, around the interior side-wall surface of dehydration barrel 1, is uniform-distribution with helical form muscle body 2, is being provided with apopore 3 near near helical form muscle body 2 tops of dehydration barrel 1 upper end.

Referring to accompanying drawing 2, when dehydration barrel is rotated, water in the clothing can be subjected to an action of centrifugal force, from clothing, break away from the madial wall that arrives dehydration barrel 1, but simultaneously because water is in passive rotation status, this just there has been the hysteresis of speed with the rotation of dehydration barrel 1, and this hysteresis, can make the side of water droplet helical form muscle body 2 on inwall transmit a pressure F1, at this moment equal and opposite in direction of water droplet, the power F2 that direction is opposite can be given in helical form muscle body 2 sides.According to the parallelogram of forces rule, F2 can be decomposed into FV1 and FV2, and FV2 can promote water droplet and rose to apopore 3 and upper end along spiral gluten body this moment, and water droplet just has been thrown out of dehydration barrel like this.

Referring to accompanying drawing 3,4,5, the helical form muscle body 2 normal direction cutting plane shapes of present embodiment can be as any of figure.

Claims
