Detailed ways

Embodiment 1

The embodiment provides a wire filter locking structure 10. As shown in FIG. 1 to FIG. 3, the wire filter locking structure 10 includes a mounting seat 1 fixedly mounted on the washing machine body 20, and the first end is provided. A locking post 2 that is movable within the mount 1 and that is movable along its own axis. In the present embodiment, the above-mentioned mount 1 is fixed to the body 20 of the washing machine by four uniformly arranged screws 5. The locking post 2 is vertically disposed, and when the locking post 2 is moved downward, the second end of the locking post 2 can prevent the knob 301 of the lint filter 30 from being loosened to achieve the purpose of locking the lint filter 30.

As shown in FIG. 1 , the mounting base 1 of the present embodiment is provided with an electromagnetic coil 3 , the locking post 2 is a steel column, and the locking post 2 is disposed in the electromagnetic coil 3 , when the electromagnetic coil 3 is energized, the above The lock cylinder 2 can be driven downward by the electromagnetic coil 3 and prevents the knob 301 from being unscrewed, at which time the chip filter 30 is locked and cannot be opened. When it is necessary to open the wire filter 30, only the electromagnetic coil 3 is reversely energized, and the lock column 2 is driven to move upward by the electromagnetic coil 3. At this time, the knob 301 can be screwed, and the wire filter 30 can be opened.

In this embodiment, considering that the reverse energization of the electromagnetic coil 3 increases the control cost and the manufacturing cost, the present embodiment is connected between the first end of the locking post 2 that is disposed in the mounting seat 1 and the top of the mounting seat 1 . The tension spring 4, when the electromagnetic coil 3 drives the locking column 2 to move downward, the tension spring 4 is stretched, and when the locking of the wire filter 30 needs to be released, the electromagnetic coil 3 is powered off, at this time, the locking column 2 is locked. It will move up to the original position under the pulling force of the tension spring 4, that is, the knob 301 of the chip filter 30 will not be prevented from unscrewing.

In this embodiment, the lock cylinder 2 is driven to move downward and upward by the electromagnetic coil 3, thereby locking and unlocking the chip filter 30. On the one hand, the electromagnetic coil 3 has high stability and long service life. In other words, the wire filter lock structure 10 of the present embodiment has a long service life; on the other hand, the lock control of the wire filter 30 can be realized, and the reliability is high.

In this embodiment, as shown in FIG. 1, a groove 302 is opened at a top position of the knob 301, and when the locking post 2 is driven to move downward by the electromagnetic coil 3, the second end of the locking post 2 is inserted into the groove. In 302, the knob 301 is not loosened, and the locking of the chip filter 30 is achieved.

In the embodiment, the structure of the groove 302 is formed at the top position of the knob 301, but the structure of the groove 302 is not limited to the above. In this embodiment, the recess 302 may not be opened on the knob 301, but the axis of the locking post 2 is directly placed on the side of the knob 301 in the loosening direction, that is, when the locking post 2 is moved downward, the locking post 2 is attached. Abutting on the side of the knob 301 in the unscrewing direction, the knob 301 is also restrained by the locking post 2 from being unscrewing, that is, the locking of the lint filter 30 is achieved. In this embodiment, the insertion slot 303 can be disposed on the side of the knob 301 in the unscrewing direction. When the locking post 2 moves downward, the second end of the locking post 2 is inserted into the insertion slot 303, and the wire can be realized. The lock of the filter 30. Among them, the loosening direction is indicated by the direction of the arrow in FIG.

In the embodiment, the locking structure 10 is locked by the above-mentioned lint filter, and the locking of the lint filter 30 can be realized only by energizing the electromagnetic coil 3, which has the characteristics of simple structure, low cost, and reliability of the locking structure 10. high.

The embodiment further provides a washing machine, as shown in FIG. 3 and FIG. 4, the washing machine comprises the above-mentioned swarf filter locking structure 10, the body 20 and the swarf filter 30, wherein the swarf filter 30 and the swarf filter The locking structures 10 are all mounted on the body 20. The washing machine of the present embodiment is provided with the above-mentioned chip filter locking structure 10, and is energized by the electromagnetic coil 3 to drive the lock column 2 to move downward to lock the wire filter 30, so that the wire filter 30 has high reliability. It can effectively prevent the user from being burnt.

In the embodiment, the wire filter locking structure 10 can lock the wire filter 30 when the washing machine is turned on, or lock the wire filter 30 when the washing machine performs hot water washing. Moreover, the washing machine of the embodiment may further be provided with a temperature sensor. When the temperature of the washing water is higher than the set temperature, the washing machine energizes the electromagnetic coil 3 of the wire filter locking structure 10, and the locking column 2 is moved downward to be inserted. Within the groove 302 of the knob 301, the lint filter 30 is locked.

Embodiment 2

The difference between the embodiment and the first embodiment is that the manner of driving the locking post 2 is different. Referring to FIG. 5 , in the embodiment, a linear motor 6 is disposed in the mounting seat 1 , and an output end of the linear motor 6 is connected to the locking post 2 . By the linear motor 6, the lock cylinder 2 can be driven to move downward into the recess 302 of the knob 301 to prevent the knob 301 from being loosened, thereby achieving locking of the chip filter 30. When the locking of the chip filter 30 needs to be released, the lock cylinder 2 is moved upward by the linear motor 6.

In the present embodiment, by providing the linear motor 6 to drive the lock cylinder 2 to move up and down, the structure of the wire filter lock structure 10 can be further simplified.
