Embodiment 1

[0054] like Figure 5 As shown, a washing machine 100 includes: an inner tub 1 , a seal 2 , a bottom plate 7 and a driving device 3 . The bottom of the inner barrel 1 is provided with a drain hole 11; the bottom plate 7 is located below the inner barrel 1; the seal 2 is set corresponding to the drain hole 11, and there is a magnetic attraction between the seal 2 and the inner barrel 1, so that the seal 2 is covered on the drain hole 11 and seal the drain hole 11; the driving device 3 is located on the bottom plate 7 and is used to drive the seal 2 to open the drain hole 11.

[0055] Preferably, as Figure 5 As shown, the seal 2 is located above the inner barrel 1; the driving device 3 includes a cylinder 34, the piston rod of which is inserted into the drain hole 11, and drives the seal 2 to move away from the drain hole 11.

[0056] The seal 2 can be located above the inner tub 1, the seal 2 can be located above the inner tub 1, preferably the seal 2 is located inside the i...

Embodiment 2

[0079] The difference from Embodiment 1 is that the seal 2 is located above the inner tub 1 , and the driving device 3 includes an oil cylinder whose piston rod is inserted into the drain hole 11 and drives the seal 2 to move away from the drain hole 11 .

[0080] The sealing member 2 can be located above the inner tub 1 , that is, the sealing member 2 is attracted to the inner wall of the inner tub 1 by virtue of the magnetic attraction force between the sealing member 2 and the inner tub 1 . The driving device 3 includes an oil cylinder, and the piston rod of the oil cylinder is inserted into the drain hole 11 from bottom to top, and drives the sealing member 2 to move upwards to open the drain hole 11 .

Embodiment 3

[0082] The difference from Embodiment 1 is that, as Figure 2 to Figure 4 As shown, the sealing member 2 is located above the inner barrel 1, and the driving device 3 includes a motor 31, a cam 32 connected to the motor 31 and a push rod 33 in contact with the outer edge of the cam 32, and the motor 31 drives the cam 32 to rotate to drive The push rod 33 is inserted into the drain hole 11 and drives the seal 2 to move away from the drain hole 11 .

[0083] The sealing member 2 can be located above the inner tub 1 , that is, the sealing member 2 is attracted to the inner wall of the inner tub 1 by virtue of the magnetic attraction force between the sealing member 2 and the inner tub 1 . The driving device 3 includes a motor 31, a cam 32 and a push rod 33. When the motor 31 rotates, it drives the cam 32 to rotate, and the change of the shape of the outer edge of the cam 32 drives the push rod 33 to move upward. The push rod 33 is inserted into the drain hole 11 and drives The s...

Abstract

The invention provides a washing machine, comprising an inner barrel, a sealing member, a bottom plate and a driving device. The bottom of the inner barrel is provided with drainage holes. The bottomplate is on the lower side of the inner barrel. The sealing member is disposed corresponding to the drainage holes, and a magnetic attraction force exists between the sealing member and the inner barrel, so that the sealing member is covered on the drainage holes and seals the drainage holes. The driving device is disposed on the bottom plate, and is used for driving the sealing member to open thedrainage holes. According to the washing machine provided by the present invention, the sealing member is absorbed on the inner barrel by the magnetic attraction force between the sealing member andthe inner barrel, to achieve sealing of the drainage holes. After washing is completed and drainage is needed, the driving device works to drive the sealing member to move toward the direction far away from the drainage holes, and the drainage holes are opened, and drainage of the washing machine is realized.

Description

technical field [0001] The invention relates to the field of household appliances, and more specifically, to a washing machine. Background technique [0002] In order to achieve the purpose of washing clothes, a washing machine is provided with a bucket for holding water, and an inner bucket for drying clothes. In order to ensure that the water in the clothes can be removed smoothly, dehydration holes are usually spread all over the peripheral wall of the inner bucket. Along with the advancement of technology, the inner barrel is changed into non-porous, that is, the peripheral wall of the inner barrel has no dehydration holes, and the washing water is completely stored in the inner barrel, and at this moment there is no water between the inner barrel and the water tank. Commonly known as there is no water in the bucket, so the water bucket has lost the meaning of holding water. At this time, the function of the water bucket is only to block the water in the clothes during ...
