Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of socket circuit structures, in particular to a socket protection structure for a refrigerator. Background Art
[0002] Refrigeration mechanical equipment such as refrigerators and ice makers usually have an AC socket and a DC socket installed at the rear power supply. The two can be used separately, and the power-on control of the two sockets can be realized through a power board and a switch. Therefore, plugs can be inserted into both sockets. To save costs, some devices do not install a power board and a switch, resulting in the DC socket having a DC 12V voltage when the AC socket is connected to the plug, which may cause a short circuit. Therefore, there are relatively large safety hazards when both can be powered on. Summary of the Utility Model
[0003] (I) Technical Problems to be Solved
[0004] The problem to be solved by the utility model is to provide a socket protection structure for a refrigerator to overcome the defect of potential safety hazards in the refrigerator socket circuit in the prior art.
[0005] (II) Technical Solutions
[0006] To solve the above technical problems, the utility model provides a socket protection structure for a refrigerator, including a body and a rear cover detachably installed on the body. The rear cover is provided with a chute, and a protection plate is movably installed on the chute. A socket fixing plate is arranged on the back of the body, and an AC socket and a DC socket are installed on the socket fixing plate. The AC socket and the DC socket are vertically arranged and the overall height is the same as that of the chute. The heights of the AC socket, the DC socket, and the protection plate are the same. When the protection plate is located at the top or bottom of the chute, one of the AC socket or the DC socket is blocked by the protection plate, so that the two sockets cannot be plugged with plugs at the same time, avoiding the occurrence of short circuits. Specifically, when the AC socket is plugged with a plug, there will be a 12V voltage at the pins of the DC socket, which will cause a short circuit. Therefore, the DC socket needs to be shielded for protection.
[0007] In some embodiments, the socket fixing plate is rectangular and is vertically fixed to the back of the body through connecting parts at both ends. The rear cover is provided with an avoidance groove corresponding to the socket fixing plate. After the rear cover is assembled, the socket fixing plate is placed in the avoidance groove, and symmetric grooves are formed on the upper part side walls of the avoidance groove to form the chute.
[0008] In some embodiments, sliding portions are symmetrically provided on the protection plate, a crossbar is provided in the middle of the protection plate, the sliding portions are assembled in the sliding grooves, the AC socket and the DC socket are located in the upper half of the socket fixing plate, and a first switch corresponding to the AC socket and a second switch corresponding to the DC socket are vertically arranged in the lower half of the socket fixing plate.
[0009] In some embodiments, a power supply board is further installed above the socket fixing plate on the back of the fuselage, the power supply board is electrically connected to the AC socket, DC socket, first switch and second switch on the socket fixing plate, an elastic buckle is provided at the top of the fuselage, and the slot on the rear cover cooperates with the elastic buckle.
[0010] (III) Beneficial effects
[0011] A socket protection structure for a refrigerator provided by the present utility model slides and installs a protection plate through a sliding groove provided on the rear cover, so as to realize that the sliding plate can always block one of the AC socket and the DC socket, preventing an external plug from simultaneously connecting to two different power sockets and avoiding potential safety hazards. Moreover, switches are installed on the socket fixing plate and cooperate with the power supply board above to control the opening and closing of the AC socket and the DC socket, further improving safety.

[0022] Refer to Figures 1 to 3, the present utility model provides a socket protection structure for a refrigerator, which includes a body 1 and a rear cover 2 detachably mounted on the body 1. An elastic buckle 15 is provided at the top of the body 1, and a slot 16 on the rear cover 2 cooperates with the elastic buckle 15. By pressing the elastic buckle 15, it can be disengaged from the slot 16 to disassemble the rear cover 2. A chute 3 is provided on the rear cover 2, and a protection plate 4 is movably mounted on the chute 3. A socket fixing plate 5 is provided on the back of the body 1, and an AC socket 6 and a DC socket 7 are mounted on the socket fixing plate 5. The AC socket 6 and the DC socket 7 are vertically arranged and the overall height is the same as that of the chute 3. Among them, the AC socket 6 is located above. Therefore, the protection plate 4 always slides from the top of the AC socket 6 to the bottom of the DC socket 7. The AC socket 6, the DC socket 7 and the protection plate 4 have the same height. When the protection plate 4 is located at the top of the chute 3, the AC socket 6 is blocked by the protection plate 4. When the protection plate 4 slides to the bottom of the chute 3, the DC socket 7 is blocked. Therefore, only one socket can be selected to connect an external plug. Specifically, when a plug is connected to the AC socket, there will be a 12V voltage at the pins of the DC socket, which will cause a short circuit. Therefore, the DC socket needs to be shielded for protection.
[0023] In some embodiments, as Figures 1 to 3 shown, the socket fixing plate 5 is rectangular and is vertically fixed to the back of the body 1 through the connecting parts 8 at both ends. An avoidance groove 9 corresponding to the socket fixing plate 5 is provided on the rear cover 2. After the rear cover 2 is assembled, the socket fixing plate 5 is placed in the avoidance groove 9, so that the socket fixing plate 5 and the electrical components on its upper part are in an embedded form. The upper part side walls of the avoidance groove 9 are symmetrically grooved to form the chute 3. The protection plate 4 is symmetrically provided with sliding parts 10. A cross bar 11 is provided in the middle of the protection plate 4. The sliding parts 10 are assembled in the chute 3. The cross bar 11 is convenient for moving the protection plate 4 up and down. The AC socket 6 and the DC socket 7 are located in the upper half of the socket fixing plate 5. The lower half of the socket fixing plate 5 is vertically arranged with a first switch 12 corresponding to the AC socket 6 and a second switch 13 corresponding to the DC socket 7. A power supply board 14 is also mounted above the socket fixing plate 5 on the back of the body 1. The power supply board 14 is electrically connected to the AC socket 6, the DC socket 7, the first switch 12 and the second switch 13 on the socket fixing plate 5. The first switch 12 and the second switch 13 are respectively used to control the circuit opening and closing of the AC socket 6 and the DC socket 7.
[0024] The socket protection structure for a refrigerator provided by the present utility model realizes the sliding installation of the protection plate by setting a chute on the rear cover, so that the sliding plate can always block one of the AC socket and the DC socket, preventing the external plug from simultaneously connecting to two different power sockets and avoiding potential safety hazards. Moreover, switches are installed on the socket fixing plate and cooperate with the power supply board above to control the opening and closing of the AC socket and the DC socket, further improving safety.
[0025] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
