Embodiment 1

[0029] This embodiment provides a lint filter locking structure 10, such as Figure 1-3 As shown, the lint filter locking structure 10 includes a mounting base 1 fixedly installed on the washing machine body 20, and a locking column 2 with one end passing through the mounting base 1 and capable of moving along its own axis. Specifically, in this embodiment, the above-mentioned mounting base 1 is fixed on the machine body 20 of the washing machine by four uniformly distributed screws 5 . The above-mentioned locking post 2 is arranged vertically, and when the locking post 2 moves downward, its other end can prevent the knob 301 of the lint filter 30 from being unscrewed, so as to achieve the purpose of locking the lint filter 30 .

[0030] Specifically, such as figure 1 As shown, the above-mentioned mounting seat 1 of this embodiment is provided with an electromagnetic coil 3, the above-mentioned locking column 2 is a steel column, and the locking column 2 is penetrated in the ...

Embodiment 2

[0039] The difference between this embodiment and the first embodiment is that the way of driving the locking column 2 is different, please refer to Figure 5 In this embodiment, a linear motor 6 is provided in the mounting base 1, the output end of the linear motor 6 is connected to the locking column 2, and the linear motor 6 can drive the locking column 2 to move downward and insert it into the groove 302 of the knob 301 , so as to prevent the knob 301 from being unscrewed, so as to realize the locking of the lint filter 30 . When the locking of the lint filter 30 needs to be released, the linear motor 6 drives the locking post 2 to move upward.

[0040] In this embodiment, the linear motor 6 is provided to drive the locking column 2 to move up and down, which can further simplify the structure of the lint filter locking structure 10 .

[0041] This embodiment also provides a washing machine, including the above-mentioned lint filter locking structure 10 , a machine body 2...

Embodiment 3

[0043] The difference between this embodiment and the first embodiment is that the locking method of the locking column 2 to the knob 301 is different. In this embodiment, a magnet is arranged on the top or side wall of the knob 301. When the locking column 2 moves downward, it will be attracted by the magnet. . The locking post 2 and the lint filter 30 are locked by the attraction of the magnet.

[0044] The present invention also provides a washing machine, comprising the above-mentioned lint filter locking structure 10 , a machine body 20 and a lint filter 30 .

Abstract

The invention belongs to the field of accessories of a washing machine, and discloses a thread chip filter locking structure and a washing machine. The thread chip filter locking structure comprises afixedly arranged mounting seat and a locking column, wherein one end of the locking column is arranged in the mounting seat, and the locking column can move along the axis; when the locking column moves, the other end of the locking column can prevent a rotary knob of a thread chip filter from being loosened. According to the thread chip filter locking structure, the locking column capable of moving along the axis is arranged in the mounting seat, so that the rotary knob of the thread chip filter can be prevented from being loosened by means of the locking column; the thread chip filter locking structure has the characteristics of being simple in structure and low in cost; furthermore, the thread chip filter is locked by means of the locking column, so that the reliability of the lockingstructure is high, and the phenomenon that a user is scalded is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of washing machine accessories, in particular to a locking structure of a lint filter and a washing machine. Background technique [0002] At present, when the washing machine is heated and washed, the lint impurities in the hot water can be filtered out through the lint filter. The existing lint filter that is screwed and installed usually does not have a locking structure, which leads to the fact that when the washing machine is heating and washing, the user can open the lint filter. If the lint filter is accidentally opened, hot water will easily flow out, causing Security incidents that burn users. [0003] For this reason, some existing lint filters have a locking structure. The locking structure uses a shape memory alloy. The temperature sensing part transmits the absorbed heat to the locking operation part, causing thermal deformation of the locking operation part. When the temperature of the washing...
