AI Technical Summary
Existing washing machine control panels are prone to accidental activation due to accidental touches, especially touch-sensitive and mechanical button panels on the machine surface, which are more likely to cause accidental touches.
Design a panel switch assembly including a core rod, a ring body, and a contact plate. The contact plate rotates synchronously with the ring body, thereby driving the contact plate to rotate. The contact plate, which is positioned opposite to the circuit board, moves. The contacts of the contact plate either make contact with or deviate from the contacts of the circuit board to avoid accidental triggering of electrical signals.
This effectively avoids accidental activation caused by unintentional touch, improving the accuracy and safety of operation.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-5As shown, this embodiment discloses a panel switch assembly, which is installed on a body 1. The body 1 has a cavity 11, and an opening is formed on one side wall of the cavity 11. The panel switch assembly is installed in the cavity 11. Specifically, the panel switch assembly includes a fixing seat 2, which is inserted into the cavity 11. The fixing seat 2 has a circular structure, and the outer wall of the fixing seat 2 is fixedly connected to the inner wall of the body 1.
[0023] The fixed base 2 is equipped with a core rod 3, which is rotatable along its own axis and axially movable. The core rod 3 includes an extension rod 31, which is inserted into the fixed base 2. Figure 4 As shown, an iron block 311 is inserted and installed on the outer wall of the extension rod 31, and a magnet 21 is inserted and installed on the inner wall of the fixing base 2. Two magnets 21 are spaced apart circumferentially along the inner wall of the fixing base 2, and the two magnets 21 form a 45-degree angle with each other along the circumferential direction of the inner wall of the fixing base 2. Rotating the extension rod 31 causes it to attract the two magnets 21 respectively, thus maintaining the extension rod 31 in different circumferential positions. Figure 2 As shown, the core rod 3 is equipped with a rotating bar 33, which extends from the axial end face of the core rod 3, i.e., the rotating bar 33 protrudes from the left end face of the core rod 3. Rotating the rotating bar 33 drives the core rod 3 to rotate. The rotating bar 33 can also be designed to be concave, i.e., a groove is cut into the left end face of the core rod 3, and the rotating bar 33 is set in the inner wall of the groove, so that there is no protrusion on the surface of the body 1. The user senses the target position of rotation by the force of the extension rod 31 attracting the two magnets 21.
[0024] like Figure 2 As shown, the extension rod 31 is fitted with a spring 8. One end of the spring 8 abuts against the fixed seat 2 and the other end abuts against the core rod 3. A limit sleeve 32 is fixedly installed on the right end of the extension rod 31.
[0025] The core rod 3 is fitted with a ring 4. The core rod 3 passes through the ring 4, and the outer peripheral wall of the core rod 3 fits against the inner peripheral wall of the ring 4. The core rod 3 and the ring 4 can rotate synchronously. Specifically, the outer wall of the core rod 3 is provided with a protrusion, and the inner wall of the ring 4 is provided with a corresponding groove. The protrusion on the outer wall of the core rod 3 is inserted into the groove on the inner wall of the ring 4 to achieve synchronous rotation of the core rod 3 and the ring 4.
[0026] like Figure 2 , Figure 3As shown, a contact plate 7 is installed on the ring body 4. The rotation of the ring body 4 causes the contact plate 7 to rotate together. The outer wall of the contact plate 7 has a protrusion, and the inner wall of the ring body 4 has a corresponding groove. The protrusion on the outer wall of the contact plate 7 is inserted into the groove on the inner wall of the ring body 4, and the contact plate 7 can move axially along the core rod 3. Specifically, the contact plate 7 is inserted into the ring body 4, and four contact plates 7 are evenly distributed around the circumference of the ring body 4. The contact plate 7 includes a support leg 72 located on the right side. An elastic body 5 is installed on the right side of the support leg 72. The elastic body 5 is made of rubber. One end of the elastic body 5 is fixed to the support leg 72, and the other end abuts against the fixing seat 2. The contact plate 7 includes a protruding plate 71. The ring body 4 has a groove 42, and the protruding plate 71 is inserted into the groove 42. The protruding plate 71 is flush with the end face of the ring body 4. The ring body 4 is provided with a protrusion 41, and the machine body 1 is provided with a limiting plate 12. Along the radial direction of the core rod 3, the limiting plate 12 and the protrusion 41 are connected by a limiting protrusion 71, so that the end face of the left end of the core rod 3 is flush with the end face of the ring body 4 and the end face of the contact plate 7.
[0027] The system includes a fixing ring 6, which is installed on the inner wall of the cavity 11. A core rod 3 passes through the fixing ring 6. A circuit board 61, which is annular, is mounted on the fixing ring 6. A contact plate 7 is positioned opposite the circuit board 61. The contact plate 7 moves closer to the circuit board 61 so that its contacts make contact with the contacts of the circuit board 61, thereby triggering an electrical signal. An indicator mark (arrow) is provided on the outer surface of the contact plate 7; an upward-pointing arrow indicates an activated state. Figure 5 The diagram shows the state of the contact plate 7 after it has been rotated. The rotation of the contact plate 7 causes the contacts of the contact plate 7 to be circumferentially offset from the contacts of the circuit board 61, thus preventing accidental triggering of electrical signals.
[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
