[0046] Reference Figures 1-9 , an embodiment of the drawer type washing equipment of the present application.

[0047] AsFigures 1-3 As shown, the drawer-type washing apparatus includes an outer cabinet 100 and a drawer assembly 200 which is pullably provided in the outer cabinet 100. The drawer assembly 200 includes a drawer cabinet 210, an outer tub 220 and an inner tub 230 which are provided in the drawer cabinet 210, and a striker switch assembly 300. The striker switch assembly 300 is used to trigger a safety switch 320 when the outer tub 220 is excessively eccentric due to uneven distribution of laundry during a washing process, cut off the power supply, and stop the operation of the washing apparatus, thereby protecting the washing apparatus from damage.

[0048] Referring to Figure 6 and Figure 7 , the striker switch assembly 300 includes a mounting seat 310, the safety switch 320, and a control lever 330.

[0049] The mounting seat 310 is fixed to the side of the drawer cabinet 210, which can be the left and right sides or the rear side. The mounting seat 310 is used to support and fix the safety switch 320 and the control lever 330, and ensure the stability and reliability of the striker switch assembly 300.

[0050] The safety switch 320 is provided on the mounting seat 310. The safety switch 320 is used to detect the position change of the control lever 330, and output an electrical signal when the control lever 330 is deflected to a predetermined position, thereby cutting off the power supply of the washing apparatus. The safety switch 320 is a micro switch, and a triggering mechanism 321 of the safety switch 320 protrudes from the housing of the safety switch.

[0051] The control lever 330 includes a connecting arm 331 and a striker arm 332. The connecting arm 331 is hingedly connected with the mounting seat 310, and a triggering portion 333 is provided on the connecting arm 331 for cooperation with the triggering mechanism 321 of the safety switch 320. The striker arm 332 extends vertically from one end of the connecting arm 331 to between the drawer cabinet 210 and the outer tub 220.

[0052] During the washing process, if the laundry in the outer tub 220 is unevenly distributed, the outer tub 220 is excessively eccentric, and the outer tub 220 will shake violently and hit the striker arm 332. As Figure 8 shown, after the striker arm 332 is hit, the connecting arm 331 is pushed to rotate, thereby causing the triggering portion 333 to trigger the safety switch 320, cut off the power supply, and stop the operation of the washing apparatus, thereby avoiding damage to the cabinet due to excessive eccentricity of the outer tub 220. When the outer tub 220 returns to balance, the control lever 330 can be automatically reset, or needs to be manually reset. This laterally mounted striker switch assembly 300 effectively utilizes the space of the side of the drawer cabinet 210, does not occupy the height space, and perfectly fits the drawer-type washing apparatus.

[0053] The drawer type washing equipment, the impact lever switch assembly 300 is installed on the side wall of the drawer box 210, the impact lever arm 332 of the control lever 330 can be bent to extend into the drawer box 210 and the outer tub 220, the side space of the drawer box 210 is effectively utilized, the height space is not occupied, and the drawer type washing equipment is suitable.

[0054] In some embodiments of the present application, as shown in Figure 7 and Figure 9 The impact lever switch assembly 300 further comprises a resilient member for automatically resetting the control lever 330 after being impacted by the outer tub 220. The resilient member can be a torsion spring 350, a compression spring, a tension spring or an elastic sheet, etc. By using the resilient member, the control lever 330 can be automatically reset without manual resetting, improving the convenience and reliability of operation.

[0055] In some embodiments of the present application, the impact lever switch assembly 300 further comprises a control lever seat 340 for supporting and fixing the control lever 330 and the resilient member. The connecting arm 331 of the control lever 330 is hingedly connected to the control lever seat 340. The control lever seat 340 can be fixed to the mounting seat 310 by screws or other fasteners, and the assembly of the control lever 330 is facilitated by providing the control lever seat 340.

[0056] In some embodiments of the present application, as shown in Figure 7 , the control lever seat 340 can be a bracket with a certain strength, and a hinge portion is arranged on the bracket for hingedly connecting with the connecting arm 331. The end of the connecting arm 331 can be provided with a rotating shaft portion 3311, for example, a protruding rotating shaft, for cooperating with the hinge portion of the control lever seat 340. The hinge portion can be two opposite lugs 341, and coaxial holes are arranged on the lugs 341, and the rotating shaft portion 3311 cooperates with the holes on the lugs 341. In another embodiment, a rotating shaft can be arranged on the control lever seat 340, and a hinge hole is correspondingly arranged on the connecting arm 331.

[0057] The control lever seat 340 can further be provided with a structure for fixing the resilient member, for example, a fixing hole for the torsion spring 350 or a support for the compression / tension spring.

[0058] In some embodiments of the present application, the resilient member is preferably a torsion spring 350, and the control lever seat 340 and the connecting arm 331 of the control lever 330 are respectively provided with fixing holes for the torsion spring 350. One end of the torsion spring 350 is fixed to the connecting arm 331, and the other end is fixed to the control lever seat 340. When the outer tub 220 impacts the impact lever arm 332, the connecting arm 331 rotates around the rotating shaft portion 3311, and the torsion spring 350 is twisted to generate a restoring force. When the outer tub 220 stops impacting, the restoring force of the torsion spring 350 makes the connecting arm 331 return to the initial position.

[0059] In some embodiments of the present application, as shown in Figure 9 The connecting arm 331 is arranged in a horizontal direction, and the trigger portion 333 is arranged vertically on the connecting arm 331. The trigger mechanism 321 of the safety switch 320 is located on one side of the trigger portion 333. When the connecting arm 331 rotates, the trigger portion 333 moves in a substantially horizontal direction, triggering the safety switch 320. This arrangement can effectively utilize space and simplify the installation of the safety switch 320.

[0060] In some embodiments of the present application, the upper end of the striker arm 332 has an inclined section 3321 connected to the connecting arm 331. When the outer tub 220 strikes the striker arm 332, the inclined section 3321 can guide the impact force in a horizontal direction, reducing the impact on the connecting arm 331 and prolonging its service life. The striker arm 332 can be a vertical rod or an inclined rod with the bottom end slightly inclined towards the outer tub 220. Multiple reinforcing ribs can be arranged on the striker arm 332 to increase the structural strength of the striker arm 332.

[0061] In some embodiments of the present application, as shown in Figure 3 The mounting seat 310 is fixed to the outer side of the drawer box 210, and the drawer box 210 has a through hole through which the control rod 330 passes. The mounting method of the mounting seat 310 on the outer side of the drawer box 210 facilitates installation and maintenance. It also avoids the situation where the gap between the outer tub 220 and the drawer box 210 is too small, preventing the installation of the striker switch assembly 300.

[0062] In some embodiments of the present application, as shown in Figure 4 The mounting seat 310 also has a sensor mounting portion for mounting the water level sensor 400. The water level sensor 400 is used to detect the water level in the tub, achieving water level control and overflow protection functions. By integrating the water level sensor 400 into the mounting seat 310, the water level sensor 400 does not need to be separately provided with a fixing member, which can reduce the number of parts, reduce manufacturing costs, avoid occupying too much space, and improve installation efficiency.

[0063] In some embodiments of the present application, as shown in Figure 5 The side plate of the drawer box 210 has a recessed profile 211 corresponding to the position of the sensor mounting portion, and the sensor mounting portion is partially located in the profile 211. This profile 211 not only enhances the rigidity of the side plate of the drawer box 210, preventing deformation and ensuring the stability of the mounting seat 310. At the same time, the sensor mounting portion can be partially located in the profile 211, reducing space occupation and avoiding excessive protrusion of the water level sensor 400.

[0064] The above examples are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing examples, for those skilled in the art, the technical solutions recorded in the foregoing examples can still be modified, or some of the technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
