Problems solved by technology

[0003] However, in the existing pulsator washing machine, the part of water filled between the inner cylinder and the side wall of the outer cylinder does not participate in washing, and the water that really participates in washing is only The part in the inner cylinder, which causes a large waste of water resources, and too much water between the inner and outer cylinders will also reduce the concentration of detergent or washing powder in the washing liquid, resulting in waste; and the area between the inner cylinder and the outer cylinder It has also become a space for dirt and dirt, such as scale in tap water, free matter in washing powder, cellulose in clothes, organic matter in the human body, and dust and bacteria brought in by clothes are very easy to stay on the side walls of the inner cylinder and the outer cylinder between

Embodiment 1

[0043] In this embodiment, the bellows 42 is connected to the drain hole 3; the drain driving device 41 includes an electromagnetic mechanism 411 and a magnetic ring 412. Wherein, the electromagnetic mechanism 411 is located on the bottom end of the outer cylinder 1 and corresponding to the bellows 42; the magnetic ring 412 is located on the lower end of the bellows 42; the electromagnetic mechanism 411 is connected to the magnetic The ring 412 tightly sucks and drives the bellows 42 to extend to seal and close the drain hole 3. The corrugated pipe 42 and the drain hole 3 are connected together by clamps, wire ties, glue, hot melt welding, etc., which is simple to assemble and easy to install. The electromagnetic mechanism 411 generates electromagnetic force, which causes the magnetic ring 412 to move downward to attract the electromagnetic mechanism 411. At this time, the bellows 42 is drawn by the magnetic ring 412, extends downward, and cooperates with the electromagnetic me...

Embodiment 2

[0053] In the second embodiment, the drainage device of the water-saving washing machine in this embodiment is basically the same as that in the first embodiment, except that: Image 6 The bellows 42 is located on the bottom end of the outer cylinder 1 and is provided corresponding to the drain hole 3; the drain driving device 41 includes an electromagnetic mechanism 411 and a magnetic ring 412. Wherein, the electromagnetic mechanism 411 is provided on the upper end of the bellows 42; the magnetic ring 412 is connected to the drain hole 3; the electromagnetic mechanism 411 is closely attracted to the magnetic ring 412 after being energized to drive the bellows 42 extends to seal and close the drain hole 3. The positional relationship among the bellows 42, the electromagnetic mechanism 411 and the magnetic ring 412 is changed, but the function of no water between the outer cylinder 1 and the inner cylinder 2 can also be realized. The electromagnetic mechanism 411 generates elect...

Embodiment 3

[0055] In the third embodiment, the drainage device of the water-saving washing machine in this embodiment is basically the same as that in the first embodiment, except that: Figure 4 with Figure 5 A telescopic mechanism 5 connected to the electromagnetic mechanism 411 and driving the electromagnetic mechanism 411 to telescopically move relative to the drain hole 3 is provided on the bottom of the outer cylinder 1. In order to better adsorb the magnetic ring 412 at the lower part of the corrugated tube 42 and meet the requirements of the distance between the inner cylinder 2 and the outer cylinder 1, a telescopic mechanism 5 is added at the bottom of the outer cylinder 1. The telescopic mechanism 5 includes a motor, The transmission mechanism and the telescopic telescopic connecting rod are connected with the electromagnetic mechanism 411. In the washing state, the motor drives the telescopic connecting rod to move upward, and the electromagnetic mechanism 411 is tightly sealed...

Abstract

The invention discloses a water-saving washing machine drainage device. The water-saving washing machine drainage device comprises an outer drum, an inner drum located in the outer drum, a drainage hole and a drainage sealing device; the drainage hole is formed in the bottom of the inner drum and communicated with an inner cavity of the inner drum and an inner cavity of the outer drum; the drainage sealing device is arranged between the drainage hole and the bottom of the outer drum; the drainage sealing device comprises a drainage driving device and a corrugated pipe; the drainage driving device drives the corrugated pipe to stretch out or draw back to seal and close or open the drainage hole. The water-saving washing machine drainage device achieves the function of achieving no water between the outer drum and the inner drum by using the drainage driving device to drive the corrugated pipe to stretch out or draw back to seal and close or open the drainage hole, water sources are saved, and meanwhile, dirt storage and accumulation between the outer drum and the inner drum can be avoided. The invention further provides a washing machine with the water-saving washing machine drainage device.

Description

Technical field [0001] The present invention relates to the technical field of washing machines, in particular to a water-saving washing machine drain device, and also to a washing machine having the water-saving washing machine drain device. Background technique [0002] From a national perspective, the current popularity of my country’s washing machine market has exceeded 76%, of which the urban market has exceeded 96%, and the rural market has exceeded 53%. With the country’s policy of promoting home appliances to the countryside and expanding domestic demand, washing machine Companies have set their sights on rural markets with greater consumption potential. In this huge market, companies are paying more and more attention to the improvement of washing machine performance to meet the needs of users. [0003] However, in the existing pulsator washing machine, the part of the water filled between the inner tube and the side wall of the outer tube does not participate in the washi...
