Washing machine

Abstract

The invention relates to a washing machine. The washing machine includes a casing, a washing tub used for storing the water and a mounting board which is mounted at a lower portion of the washing tuband is used for supporting the washing tub, wherein the mounting board is connected with the casing through a damping part, the washing tub is rotatably arranged relative to the mounting board, the mounting board is provided with a water retaining ring to form a concave cavity structure, the bottom of the concave cavity structure is connected with a drainage pipe and is communicated with a drainage port of the washing machine, an outer side of the washing tub is provided with multiple drainage channels, an upper end of the drainage channels is provided with a dewatering port which is communicated with an inner portion of the washing tub, a lower end of the drainage channels extends to the bottom of the washing tub along the tub wall of the washing tub, the lower end is further provided with a water outlet, and the water outlet is arranged at an inner side of the water retaining ring. The washing machine is advantaged in that an outer tub structure is omitted, and capacity expansion ofthe washing machine is achieved.

Description

technical field [0001] The invention relates to laundry equipment, in particular to a washing machine. Background technique [0002] Existing pulsator washing machines generally consist of a washing tub, an outer tub, a vibration-damping component and a power system. During washing and dehydration, the washing tub rotates relative to the outer tub so that the clothes interact with the washing water to achieve the effect of washing or dehydrating the clothes. Purpose, wherein, the outer tub is used as a water bucket, and does not come into contact with the clothes during the laundry process, and the outer tub is installed outside the washing tub to provide support for the washing tub. The outer tub of the existing washing machine is larger than the washing tub, As a result, there is a large amount of washing water stored between the inner and outer tubs, which cannot be fully utilized. This arrangement is not only unfavorable for water saving, but also causes the overall volu...

[0002] Existing pulsator washing machines generally consist of a washing tub, an outer tub, a vibration-damping component and a power system. During washing and dehydration, the washing tub rotates relative to the outer tub so that the clothes interact with the washing water to achieve the effect of washing or dehydrating the clothes. Purpose, wherein, the outer tub is used as a water bucket, and does not come into contact with the clothes during the laundry process, and the outer tub is installed outside the washing tub to provide support for the washing tub. The outer tub of the existing washing machine is larger than the washing tub, As a result, there is a large amount of washing water between the inner and outer tubs, which cannot be fully utilized. This setting is not conducive to water saving, but also causes the overall volume of the washing machine to be too large

The Chinese invention patent with the patent number of 99230455.5 discloses a single-tub water-saving washing machine. A water collecting device is provided at the mouth of the washing bucket, and the water collecting mouth of the water collecting device is surrounded by the mouth of the washing bucket. The water collecting device located at the mouth of the bucket is connected to several drainage pipes, which are symmetrically arranged from top to bottom along the outer wall of the washing bucket. When drying, the water collecting device collects the centrifugal water flow caused by high-speed rotation and sends it downward. Guide draining, although the patent omits the outer tub, but when the washing machine is dehydrating, the washing water will be concentrated in the water collecting chamber under the action of centrifugal force after entering the water collecting device, and it is difficult to flow downward along the drain pipe, resulting in washing The water concentrates on the upper end of the washing bucket, which makes the upper and lower ends of the washing bucket unbalanced, especially when there is a lot of residual water in the washing bucket, most of the washing water is concentrated in the water collecting chamber and is not discharged, which increases the overall center of gravity of the inner bucket and increases the vibration of the inner bucket. Increases the working load of the dehydration motor, which is easy to damage the motor
