Description

Technical Field

[0001] The utility model belongs to the technical field of laundry equipment, and particularly relates to a drum knock switch and a washing machine. Background Art

[0002] Washing machines are widely used in households as a convenient laundry appliance. For example, in a commonly used pulsator washing machine, the washing tub is prone to shake violently and hit the wall of the washing tub when the washing tub is dehydrating. Therefore, in order to force the motor that drives the washing tub to dehydrate to stop before the washing tub hits the wall of the washing tub, a tub-collision switch is usually provided in the relevant technology. When the washing tub shakes beyond the set limit and hits the tub-collision switch, the tub-collision switch can disconnect the circuit to stop the motor from driving the washing tub to dehydrate.

[0003] Since the shaking of the washing tub will directly collide with the bump switch, the collision will cause the bump switch to bear the impact directly, thereby causing wear. What is more serious is that if the collision is frequent or the collision force is too great, the wear degree of the bump switch will increase sharply, and even cause direct damage to the bump switch, seriously affecting the service life of the bump switch. Therefore, how to improve the service life of the bump switch is an urgent problem to be solved. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the prior art and to propose a drum-bumping switch and a washing machine. The technical problem to be solved by the utility model is: how to increase the service life of the drum-bumping switch.

[0010] In the above-mentioned barrel bumping switch and washing machine, a mounting hole is provided on the mounting seat, and the barrel bumping switch body is plugged into the mounting hole.

[0011] In the above-mentioned drum-impact switch and washing machine, reinforcing ribs are arranged on the mounting seat, and the reinforcing ribs extend to the side walls of the rotating shaft.

[0012] In the above-mentioned barrel bumping switch and washing machine, the mounting hole is T-shaped, and the end of the barrel bumping switch body is adapted to the mounting hole.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] Embodiment 1:

[0026] A barrel knock switch, such as Figures 1 to 4 As shown, it includes a barrel knocking switch body 1, and a contact wheel 3 is rotatably provided at the end of the barrel knocking switch body 1. The contact wheel 3 is used to contact and collide with the washing tub 11, and the rotation axis of the contact wheel 3 is parallel to the rotation axis of the washing tub 11. Specifically, a mounting seat 2 is provided at the end of the barrel knocking switch body 1, and the contact wheel 3 is rotatably provided on the mounting seat 2. A rotating shaft 4 is provided on the mounting seat 2. Preferably, the mounting seat 2 and the rotating shaft 4 are integrally provided, and an adapter hole 5 is provided on the contact wheel 3. In this embodiment, the adapter hole 5 is provided along the central axis of the contact wheel 3, the rotating shaft 4 and the adapter hole 5 are coaxially provided, the rotating shaft 4 is inserted into the adapter hole 5 and the two are rotatably matched. As another scheme, the adapter hole 5 can also be eccentrically provided on the contact wheel 3.

[0027] When the washing tub 11 contacts and collides with the contact wheel 3, the contact wheel 3 can rotate. Since the contact wheel 3 can unload the force by rotating when contacting and colliding with the washing tub 11, the direct impact and wear on the collision tub switch body 1 can be reduced, thereby increasing the service life of the collision tub switch.

[0028] It needs to be further explained that when the washing tub 11 contacts and collides with the contact wheel 3, the outer wall of the contact wheel 3 rotates and cooperates with the outer wall of the washing tub 11, which can effectively reduce the wear on the washing tub 11 and the contact wheel 3, and reduce the direct impact on the tub switch body 1. Preferably, the contact wheel 3 can be made of a material with good wear resistance to ensure the service life of the contact wheel 3.

[0029] Specifically, a mounting hole 6 is opened on the mounting seat 2, and the bump barrel switch body 1 is inserted into the mounting hole 6, so as to realize the connection between the mounting seat 2 and the bump barrel switch body 1. In other embodiments, the mounting seat 2 and the bump barrel switch body 1 can also be directly integrated.

[0030] Furthermore, the mounting hole 6 is T-shaped, and the end of the bumper switch body 1 is adapted to the mounting hole 6, so that the connection between the bumper switch body 1 and the mounting base 2 can be more stable, and the installation is also more convenient, which is conducive to the maintenance and replacement of the bumper switch.

[0031] An arc surface 1 8 is provided in the mounting hole 6, and an arc surface 2 9 is provided on the barrel-colliding switch body 1. The arc surface 1 8 is in contact with the arc surface 2 9. The arc surface 1 8 cooperates with the arc surface 2 9 to disperse the impact force generated when the contact wheel 3 contacts and collides with the washing tub 11, thereby effectively reducing the impact on the barrel-colliding switch body 1.

[0032] The mounting base 2 is provided with reinforcing ribs 7, and the reinforcing ribs 7 extend to the side walls of the rotating shaft 4, thereby effectively enhancing the structural strength of the mounting base 2 and the rotating shaft 4, improving the reliability of the structure and increasing the service life.

[0033] Embodiment 2:

[0034] The difference between the second embodiment and the first embodiment is that Figure 5 As shown, a rotating shaft portion 12 is provided at the end of the barrel knock switch body 1, and the contact wheel 3 is rotatably provided on the rotating shaft portion 12. A through hole 13 is provided on the contact wheel 3 to rotatably cooperate with the rotating shaft portion 12. In this embodiment, the through hole 13 is provided along the central axis of the contact wheel 3. As another solution, the through hole 13 can also be eccentrically provided on the contact wheel 3.

[0035] Embodiment three:
