Referring to fig. 2 to fig. 3, fig. 2 is a schematic structural diagram illustrating a first state of a mechanical switch in the refrigerator shown in fig. 1; fig. 3 is a structural diagram illustrating a second state of a mechanical switch in the refrigerator shown in fig. 1. The mechanical switch 50 provided by the embodiment of the present application includes a housing 510, a trigger 520, and a driving mechanism 530. Wherein, the housing 510 comprises an upper cover 513 and a base 514, and the upper cover 513 and the base 514 are connected to form the housing 510 with a receiving space 512.

The trigger 520 is disposed in the accommodating space 512. The trigger 520 includes a stationary contact 521 and a movable contact 522. The fixed contact 521 is disposed on the base 514, the fixed contact 521 is fixedly connected with the base 514, and the movable contact 522 is movably connected with the housing 510. In some embodiments, the fixed contact 521 is fixedly connected to the base 514, and the movable contact 522 is movably connected to the upper cover 513. It is understood that the specific positions of the fixed contact 521 and the movable contact 522 in the housing 510 may be set arbitrarily, and it is only necessary that the movable contact 522 can contact with the fixed contact 521 within a certain range, and the specific positions of the fixed contact 521 and the movable contact 522 are not specifically limited in this application.

The driving mechanism 530 comprises a button 531 and a push rod 532, and the push rod 532 is fixedly connected with the button 531. The button 531 is disposed through the housing 510, and a guide groove is disposed in the housing 510, the button 531 can move in the guide groove toward a direction close to the base 514 and a direction away from the base 514, so as to ensure that the button 531 can move relative to the housing 510. During movement, a portion of the structure of button 531 moves into housing 510.

A plunger 532 is disposed in the receiving space 512, and the plunger 532 can move following the button 531 to drive the movable contact 522 to contact with the stationary contact 521. The plunger 532 is disposed on a side of the button 531 near the stationary contact 521 and extends toward the stationary contact 521, and the plunger 532 drives the movable contact 522 to move toward the stationary contact 521. The plunger 532 includes a first portion fixedly connected to the button 531 and a second portion extending from the first portion toward the stationary contact 521. The first part and the second part are connected through an arc, so that the contact area of the ejector rod 532 and the metal elastic sheet is larger, and the abutting effect of the ejector rod 532 and the metal elastic sheet is better. The first and second portions may be integrally formed. In other embodiments, the plunger 532 may also be disposed on a side of the button 531 near the stationary contact 521, and may be disposed obliquely from the first portion to a direction directly near the stationary contact 521.

Wherein the push bar 532 is integrally formed with the button 531. With the push rod 532 and the button 531 integrally formed, during the movement, the push rod 532 directly moves together with the button 531, thereby driving the movable contact 522 to contact with the stationary contact 521. Compared with the prior art in which the pressing-on stroke of the mechanical switch 50 is controlled by pressing the rotating block by the button 531, the rotation of the rotating block is unstable, which results in a larger error of the switch-on stroke. The design of the push button 531 and the push rod 532 in this embodiment simplifies the on stroke of the mechanical switch 50.

It is understood that in other embodiments, the push rod 532 and the button 531 may be fixedly connected by other means, such as adhering the push rod 532 and the button 531 by glue, fixing the push rod 532 and the button 531 by mortise and tenon structure, or fixing the push rod 532 and the button 531 by snap structure. It should be noted that the connection manner of the push rod 532 and the button 531 is not limited to the above connection manners, and may be other connection manners, and only the push rod 532 can directly move along with the button 531, which is not limited herein in the embodiment of the present application.

The mechanical switch 50 further includes a metal dome 550, and the metal dome 550 is connected to the movable contact 522. The metal dome 550 may be used to drive the moving contact 522 to move toward the stationary contact 521 until the moving contact 522 abuts against the stationary contact 521. The metal dome 550 may also be used to provide a moving force to the movable contact 522, such that the movable contact 522 moves away from the stationary contact 521. Specifically, when the button 531 moves closer to the base 514, the plunger 532 abuts against the metal dome 550 and drives the movable contact 522 to move toward the stationary contact 521, so as to contact the movable contact 522 with the stationary contact 521. When the button 531 moves away from the base 514, the plunger 532 moves along with the button 531 to move away from the metal dome 550, and the metal dome 550 drives the moving contact 522 to move away from the fixed contact 521, so that the fixed contact 521 and the moving contact 522 are separated.

It should be noted that the metal elastic sheet 550 may be a common elastic sheet, and a conductive metal substance is laid on the outer surface of the elastic sheet, or the elastic sheet may be made of a metal material having a conductive capability and an elastic function. The embodiment of the present application is not limited to the specific material of the metal dome 550, and the metal dome 550 only needs to be conductive and have a certain elasticity.

The mechanical switch 50 further includes a spring 560, and one end of the spring 560 is connected to the button 531 and the other end is disposed at the base 514. Specifically, one end of the spring 560 is disposed in the receiving cavity of the button 531, and the spring 560 is compressed in the receiving cavity of the button 531 when the button 531 moves in a direction approaching the base 514. By compressing the spring 560 within the button 531, assembly space can be saved, resulting in a reduction in the volume of the mechanical switch 50. It should be noted that one end of the spring 560 may also be directly connected to the end of the button 531 near the base 514, and the spring 560 is compressed when the button 531 moves closer to the base 514. Under the condition that the spring 560 is ensured to be compressed and have elasticity, the button 531 does not need to be provided with an accommodating cavity for accommodating the spring 560, the processing flow of the button 531 can be reduced, and the installation of the button 531 and the spring 560 is simpler and more convenient. It should be noted that the other end of the spring 560 may be fixedly connected to the base 514, or may be only in contact with the base 514, and only one end of the spring 560 is required to be connected to the button 531, which is not limited in this application.

The spring 560 can provide a force for moving the button 531 away from the base 514, the plunger 532 moves away from the metal dome 550 along with the button 531 towards the direction away from the base 514, and the metal dome 550 moves away from the fixed contact 521 under the action of its own elastic force and drives the movable contact 522 to move away from the fixed contact 521 until the fixed contact 521 is separated from the movable contact 522.

The size of the compressed spring 560 is required to satisfy the following conditions: when the spring 560 can no longer be compressed, the plunger 532 can bring the stationary contact 521 into contact with the movable contact 522.

The mechanical switch 50 further includes a pin 570, the pin 570 has a certain conductive function, the pin 570 is used for contacting the control module, and sends a signal to the control module through the connection of the pin 570, and the control module sends a control signal to the function module 40 according to the state of the door body 20, so as to control the opening or closing of the function module 40.

The pins 570 include a first pin 572 and a second pin 571, and the first pin 572 and the second pin 571 are spaced apart. One end of the first pin 572 is connected to the stationary contact 521, and the other end of the first pin 572 is disposed outside the housing 510. One end of the second pin 571 is electrically connected to the metal dome 550, and the other end of the second pin 571 is disposed outside the housing 510.

The other end of the first pin 572 and the other end of the second pin 571 outside the housing 510 may be inserted into a socket, and the socket is directly electrically connected to the other functional module 40 for controlling the connection or disconnection of the other load. Specifically, one end of the second pin 571 is electrically connected to the metal spring 550, the metal spring 550 is connected to the movable contact 522, the fixed contact 521 is connected to one end of the first pin 572, and when the fixed contact 521 is connected to the movable contact 522, one end of the first pin 572 and one end of the second pin 571 are conducted, so that the circuit can be connected. When the fixed contact 521 and the movable contact 522 are separated, one end of the first pin 572 and one end of the second pin 571 are disconnected, and thus the circuit is broken.

Referring to fig. 2 and 3, when the button 531 is not moved into the housing 510, the spring 560 is not compressed in the button 531, the fixed contact 521 is separated from the movable contact 522, and one end of the first pin 572 is disconnected from one end of the second pin 571. When the button 531 moves toward the base 514, the spring 560 is partially compressed, and the plunger 532 abuts against the metal dome 550, so that the moving contact 522 contacts with the stationary contact 521, and one end of the first pin 572 and one end of the second pin 571 are connected.

In other embodiments, when the fixed contact 521 completely abuts against the movable contact 522, the button 531 may move into the housing 510 completely, that is, the door 20 completely contacts the refrigerator body 10, and there is no gap between the door 20 and the refrigerator body 10, so that energy consumption may be reduced, and the refrigerator 1 may work better.

With reference to fig. 4 to 5, fig. 4 is a first top view of a refrigerator according to an embodiment of the present disclosure; fig. 5 is a second top view of a refrigerator according to an embodiment of the present application. The mechanical switch 50 provided by the embodiment of the present application is disposed on the box 10, and the button 531 in the mechanical switch 50 is disposed outside the box 10 in a protruding manner. When the door 20 is opened relative to the cabinet 10, the movable contact 522 is disconnected from the stationary contact 521, so that the function module 40 is opened; when the door 20 is closed with respect to the cabinet 10, the movable contact 522 is connected to the stationary contact 521 so that the function module 40 is closed.

Specifically, when the door 20 is closed with respect to the housing 10, the door 20 may abut the button 531 of the mechanical switch 50. The button 531 moves relative to the housing 510 along the guiding slot in a direction approaching the base 514, when a part of the button 531 moves into the housing 510, the spring 560 is gradually compressed on the base 514, the push rod 532 moves in a direction approaching the base 514 along with the button 531, the push rod 532 drives the metal sheet to move towards the fixed contact 521 after contacting the metal spring sheet 550, and the moving of the metal sheet drives the moving contact 522 to move towards the fixed contact 521 until the moving contact 522 is connected with or abutted against the fixed contact 521. When the movable contact 522 is connected to the fixed contact 521, and the first pin 572 and the second pin 571 are conducted, the control system detects the conduction of the mechanical switch 50, and then sends a control signal to the functional module 40 to control the opening or closing of the functional module 40.

The button 531 drives the plunger 532 to move in a direction away from the base 514, the metal spring piece 550 moves in a direction away from the fixed contact 521 under the action of the elastic force of the metal spring piece 550, and the metal spring piece 550 drives the movable contact 522 to move in a direction away from the fixed contact 521 until the fixed contact 521 is away from the movable contact 522. When the fixed contact 521 is disconnected from the movable contact 522, the first pin 572 and the second pin 571 are not conducted, and then the control system detects that the mechanical switch 50 is disconnected, and sends a control signal to the functional module 40 to control the functional module 40 to be opened or closed.

Referring to fig. 6, fig. 6 is a third top view of the refrigerator according to the embodiment of the present application. The mechanical switch 50 can also be arranged on the door body 20, and when the door body 20 is closed, the mechanical switch 50 is triggered to be opened through the contact between the door body 20 and the mechanical switch 50; when the door 20 is opened, the door 20 is disconnected from the mechanical switch 50, and the mechanical switch 50 is triggered to close.
