Problems solved by technology

[0002] During the washing / rinsing process of traditional pulsator or drum washing machines, the clothes will inevitably drop some insoluble particles and lint. If these impurities cannot be effectively removed, they will be adsorbed on the outer wall of the inner cylinder and the inner wall of the outer cylinder for a long time. If it is not cleaned for a long time, it is easy to breed mold. This situation will firstly cause the filter device of the washing machine to be blocked by flocs and debris, resulting in failure of the washing machine, and secondly, it will cause secondary pollution of clothes and endanger human health.
[0003] In order to solve the above problems, a circulation pipeline is connected to the outer cylinder of the washing machine, and a filter device is installed on the circulation pipeline. When the washing machine performs washing / rinsing operations, the water in the outer cylinder of the washing machine is circulated to the filter device for filtration and then returned to the In the outer cylinder, impurities such as thread scraps can be effectively filtered out, but the existing filter device only has the function of filtering and does not have the function of automatically removing impurities. Therefore, the user needs to clean the filter device regularly, which is inconvenient to use, and if the cleaning is not Timely, it is very easy to cause blockage of the filter device and affect the normal use of the washing machine
[0004] In view of the above problems, it is urgent to provide a new filter device to solve the problems of inconvenient use and blockage of the filter device caused by the inability of the existing filter device to automatically clean up impurities.

Embodiment 1

[0029] This embodiment provides a filtering device, such as figure 1 As shown, it has a sealed cavity 1, a water inlet 2 is opened on one side of the sealed cavity 1, a sewage outlet 3 is opened on the side opposite to the water inlet 2 on the sealed cavity 1, and a sewage outlet 3 is opened on the sealed cavity 1 There is also a water outlet 4 at the bottom of the water outlet, and a filter unit 5 for filtering water is provided at the water outlet 4, which can be a filter screen, a filter membrane, etc.

[0030] The sewage outlet 3 is closed by a switch assembly. In this embodiment, the switch assembly includes a baffle 6 and a first spring 7 arranged outside the sealed cavity 1. One end of the first spring 7 is fixed by a bracket 8, and the other end is connected to the baffle 6 , under the elastic force of the first spring 7, the baffle plate 6 closes the sewage outlet 3.

[0031] An anti-backflow device is also provided at the water inlet 2 to prevent backflow of water e...

Embodiment 2

[0037] This embodiment provides a filtering device, such as figure 2 As shown, its structure is basically the same as that of Embodiment 1, with a sealed cavity 1, a water inlet 2 is opened on one side of the sealed cavity 1, and a sewage discharge is opened on the side opposite to the water inlet 2 on the sealed cavity 1 The port 3 is also provided with a water outlet 4 at the bottom of the sealed cavity 1, and a filter unit 5 for filtering water is arranged at the water outlet 4, and the sewage outlet 3 is closed by a switch assembly.

[0038] The difference is that the switch assembly of this embodiment includes a solenoid valve 10 arranged at the sewage outlet 3 and a pressure switch arranged in the sealed cavity 1. When the pressure in the sealed cavity 1 reaches a certain value, the pressure switch controls The electromagnetic valve 10 is opened, and the sewage outlet 3 is opened for sewage discharge. In this embodiment, the pressure switch includes a second spring 11 ...

Embodiment 3

[0042] This embodiment provides a washing machine, such as image 3 As shown, it includes a box body 14 , an outer cylinder 15 and an inner cylinder 16 arranged in the box body 14 , a circulating pump 17 and a filtering device 18 as described in the first or second embodiment. A water inlet pipe 19 is arranged on the outer cylinder 15 . The outer cylinder 15, the circulating pump 17 and the filtering device 18 are connected in sequence through the circulating pipe 20 to form a circulating filtering circuit. A drain pipe 21 is connected between the circulation pump 17 and the filter device 18 through a tee, and a solenoid valve 22 is arranged on the drain pipe 21. The sewage outlet 3 of the filter device 18 is connected to the drain pipe 21 through a sewage pipe 23, and the connection point is located at the solenoid valve. After 22.

[0043] Its working process is that when the washing machine is in the washing / rinsing process, the circulating pump 17 is turned on to circula...

Abstract

The invention discloses a filter device and a washing machine and relates to the technical field of washing machines. The filter device and the washing machine are designed in order to solve the problems that sundries filtered by existing washing machines cannot be cleaned automatically, etc. The filter device is equipped with a sealed cavity, wherein the sealed cavity comprises a water inlet, a water outlet and a drain outlet; a filter unit is disposed at the water outlet; the drain outlet is disposed close to the water inlet side of the filter unit; and a switch assembly is disposed at the drain outlet. Water in the washing machine enters the sealed cavity, is filtered by the filter unit and then discharged; filtered impurities are accumulated in the upper part of the filter unit; when too many impurities are accumulated in the upper part of the filter unit and lead to blocking and the pressure inside the sealed cavity is too large, the drain outlet can be opened by the switch assembly, and the impurities are discharged from the filter device via the drain outlet under washing of water flows; and when the pressure inside the sealed cavity decreases, the drain outlet can be sealed by the switch assembly, filtering and collection of the impurities can be continued, the impurities can be collected and cleaned automatically, and the blocking of the filter device can be avoided effectively.
