Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a refrigerator. BACKGROUND

[0002] A refrigerator is a refrigeration device used to maintain a constant low temperature, mainly used to store food and other items. The refrigerator obtains low temperature through the change of the physical state of the refrigerant, and provides storage space. A household refrigerator usually has one or more compartments, and can achieve continuous refrigeration by consuming electrical energy. A large number of electrical equipment are installed in the refrigerator, so how to ground the refrigerator to avoid electric shock accidents is an extremely important design consideration.

[0003] In the conventional technology, a grounding reinforcing iron is generally installed on the shell of the refrigerator, and the leakage current inside and outside the refrigerator is connected to the grounding reinforcing iron through the wire, the grounding reinforcing iron is connected with the ground wire of the power line, and the ground wire of the power line is connected with the socket. Finally, the leakage current is guided into the ground through the ground wire of the socket to achieve the purpose of grounding protection. However, due to the consideration of rust resistance and durability, the outer surface of the refrigerator shell is processed to have a paint surface, and the contact between the paint surface and the grounding reinforcing iron will cause insulation, so that the shell of the refrigerator cannot effectively conduct electricity with the grounding reinforcing iron. After the user touches the shell of the refrigerator, there is a safety hazard of electric shock, which greatly affects the safety of the refrigerator. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a refrigerator to solve the problem of electric shock safety hazard and affect the safety of use.

Finally, the conductive assembly is electrically connected with the grounding reinforcement and the grounding connecting piece. In this way, even if the outer wall of the cabinet has a paint surface for rust prevention, an electrical connection relationship can still be formed between the conductive fin and the grounding connecting piece, so that the leakage current on the cabinet can be conducted to the grounding connecting piece through the conductive fin, then conducted to the grounding reinforcement from the grounding connecting piece, and then conducted to the conductive assembly through the grounding reinforcement, and finally conducted to the ground through the conductive assembly, preventing the user from being electrocuted when touching the cabinet and improving the safety and reliability of the refrigerator.

If present, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in the present application are for illustrative purposes only and are not the only embodiment.

[0052] Referring to Figure 1 , Figure 2 and Figures 4 to 7 , a structural diagram of a refrigerator 100 according to an embodiment of the present application is shown, which includes a cabinet 10, a grounding reinforcement 30, a grounding connector 40, and a conductive assembly 50.

[0053] The cabinet 10 is provided with an assembly hole 11, and the hole wall of the assembly hole 11 is provided with a conductive fin 20 protruding towards the hole center direction.

[0054] Specifically, the conductive fin 20 and the cabinet 10 are of an integrated structure. For example, when the assembly hole 11 is processed by punching process, the conductive fin 20 is integrally formed with the assembly hole 11, and such an integrated structure can obtain better structural performance and strength.

[0055] Of course, in other alternative embodiments, the conductive fin 20 can also be in a split structure with the cabinet 10, and the conductive fin 20 is installed at the hole wall of the assembly hole 11 by at least one of screwing, clamping, and bonding.

[0056] The grounding reinforcement 30 is arranged on the cabinet 10, and the grounding reinforcement 30 is provided with a mounting hole 31 arranged in position with the assembly hole 11, and the three orthogonal projections of the conductive fin 20 fall into the mounting hole 31. That is, at least part of the conductive fin 20 extends into the mounting hole 31 along the radial direction of the mounting hole 31.

[0057] The grounding connector 40 is arranged in the mounting hole 31 and the assembly hole 11, and the grounding connector 40 is electrically connected with the conductive fin 20 and the grounding reinforcement 30; the conductive assembly 50 is electrically connected with the grounding reinforcement 30 and the grounding connector 40, and the conductive assembly 50 is used to guide the leakage to the ground.

[0058] In summary, the implementation of the technical scheme of the embodiment will have the following beneficial effects: in the refrigerator 100 of the present scheme, the grounding reinforcement 30 is placed on the cabinet 10 during assembly, so that the mounting hole 31 is in position with the assembly hole 11, and the orthogonal projection of the conductive fin 20 on the grounding reinforcement 30 falls into the mounting hole 31; then the grounding connector 40 is arranged and mounted in the mounting hole 31 and the assembly hole 11, so that the grounding connector 40 is electrically connected with the conductive fin 20 and the grounding reinforcement 30, and finally the conductive assembly 50 is electrically connected with the grounding reinforcement 30 and the grounding connector 40; in this way, even if the outer wall of the cabinet 10 has a paint surface for rust prevention, the conductive fin 20 and the grounding connector can still be electrically connected, so that the leakage on the cabinet 10 can be conducted to the grounding connector 40 through the conductive fin 20, and then conducted to the grounding reinforcement 30 from the grounding connector 40, and then conducted to the conductive assembly 50 through the grounding reinforcement 30, and finally guided to the ground through the conductive assembly 50, realizing reliable grounding of the refrigerator 100, preventing electric shock accidents when the user touches the cabinet 10, and improving the safety and reliability of the refrigerator 100.

[0059] It is easy to understand that the conductive fin 20 is made of a conductive material, such as metal. The surface of the conductive fin 20 for contacting the grounding connector 40 does not have a paint surface, but a metal surface. The metal surface can be in contact with the grounding connector 40 made of metal to achieve electrical connection effect.

[0060] In actual production, the way to obtain the metal surface of the conductive fin 20 includes at least but not limited to the following two: the first is to remove the paint on the conductive fin 20 to expose the metal surface when punching the assembly hole 11; the second is to remove the paint on the conductive fin 20 by the grounding connector 40 during the process of installing the grounding connector 40 into the mounting hole 31 and the assembly hole 11 to expose the metal surface. The specific way can be selected flexibly according to actual needs.

[0061] In order to further improve the effectiveness of the leakage current on the box body 10 to the grounding connector 40, on the basis of the above embodiment, the conductive fin 20 is provided with at least two, and the at least two conductive fins 20 are arranged in the circumferential direction of the assembly hole 11, and the at least two conductive fins 20 are electrically connected with the grounding connector 40 at the same time.

[0062] In actual installation, the two conductive fins 20 are in extrusion contact with the grounding connector 40 to form the effect of being pressed against each other, which can ensure that the grounding connector 40 is in close contact with the two conductive fins 20 at the same time, and eliminates the problem that the cooperation gap between the conductive fin 20 and the grounding connector 40 may be caused by factors such as machining size error when a conductive fin 20 is arranged alone, resulting in that the box body 10 and the grounding connector 40 and the grounding reinforcement 30 cannot be effectively conductive.

[0063] Please continue to refer to Figure 5 , further, in a preferred embodiment of the present application, the conductive fin 20 is provided with three, and the three conductive fins 20 are uniformly distributed along the circumferential direction of the assembly hole 11. That is, the adjacent two conductive fins 20 are arranged at an interval of 120°. This kind of uniform structure design helps to reduce the processing difficulty and cost.

[0064] The conductive fin 20 has a top point away from the hole wall of the assembly hole 11, and the three top points surround to form an insertion hole 60, and the hole diameter of the insertion hole 60 is smaller than the diameter of the grounding connector 40.

[0065] Specifically, the adjacent two top points are connected by an arc-shaped connecting line, and the three arc-shaped connecting lines surround to form a circular insertion hole 60.

[0066] In this way, the installation interference between the conductive fin 20 and the grounding connector 40 can be ensured, so that when the grounding connector 40 is inserted into the assembly hole 11 through the mounting hole 31, the grounding connector 40 will generate extrusion force on the conductive fin 20 to make the conductive fin 20 bend and deform, so that the side surface of the conductive fin 20 and the outer circumferential surface of the grounding connector 40 form a larger contact area, which ensures the conductive connection and improves the leakage conduction efficiency.

[0067] Please continue to refer to Figure 5In order to avoid the stress concentration of the root of the electrically-conductive fin 20 connected with the hole wall of the assembly hole 11 when the electrically-conductive fin 20 is pressed and bent by the grounding connector 40, a recess 70 is formed between the two adjacent electrically-conductive fins 20, and the recess 70 and the electrically-conductive fin 20 are connected by an arc surface. It is easy to understand that the arc surface can effectively reduce the stress concentration effect and improve the structural safety of the electrically-conductive fin 20.

[0068] In addition, on the basis of any of the above embodiments, the side of the electrically-conductive fin 20 away from the hole wall of the assembly hole 11 is formed as a circular arc surface. On the one hand, the electrically-conductive fin 20 can be formed as a circular arc structure, which is more convenient for punching processing and forming, and ensures the processing quality and precision; on the other hand, the pressing contact surface between the electrically-conductive fin 20 and the grounding connector 40 is a circular arc surface, which can effectively avoid scratching the grounding connector 40, prevent the grounding connector 40 from being connected and reduce the service life; in addition, the structure of the electrically-conductive fin 20 is uniform, and the stress when the electrically-conductive fin 20 is pressed by the grounding connector 40 can also be more uniform, which is more prone to bending deformation to avoid the grounding connector 40, thereby improving the installation effectiveness of the grounding connector 40.

[0069] Please continue to refer to Figures 1 to 3 In an embodiment of the present application, the cabinet 10 includes a shell 12 and a control panel box 13. The shell 12 is specifically a U-shaped plate formed by integrally bending a stainless steel plate. The forming method is simple, and the structural performance is good. During installation and use, the middle plate body of the shell 12 is located at the top of the refrigerator 100, and the two side plate bodies are vertically arranged below the middle plate body along the height direction of the cabinet 10.

[0070] The shell 12 is provided with an assembly hole 11, and the shell 12 is provided with a receiving portion 121. The receiving portion 121 is specifically a through groove structure formed on the middle plate body of the shell 12, and the size and shape thereof are respectively matched with the size and shape of the control panel box 13.

[0071] The control panel box 13 is arranged in the receiving portion 121, and the control panel box 13 is provided with a threaded hole 131 aligned with the assembly hole 11. The assembly hole 11 is located between the threaded hole 131 and the mounting hole 31. The grounding connector 40 is a grounding screw, which is screwed into the threaded hole 131 after passing through the mounting hole 31 and the assembly hole 11.

[0072] During installation, the grounding screw is screwed into the threaded hole 131 after passing through the mounting hole 31 and the assembly hole 11, which can realize the assembly and fixation of the control panel box 13, the shell 12, the grounding reinforcing part, and the grounding connector 40. The threaded connection method has the advantages of simple structure, high connection strength, and convenient and labor-saving disassembly and assembly.

[0073] Of course, other optional embodiments of the above threaded connection can also be replaced by snap connection, adhesion and the like, which are also within the protection scope of the present application, and will not be described here.

[0074] In the present application, the anti-electric shock of the refrigerator 100 mainly involves guiding the leakage of the electrically conductive components inside the refrigerator 100 and the leakage of the electrically conductive components outside the refrigerator 100 to the ground, so as to avoid the risk of electric shock caused by the leakage current flowing into the body after the user contacts the refrigerator 100.

[0075] Please continue to refer to Figure 2 and Figure 7 Based on this, in one embodiment, the mounting hole 31 is provided with two first mounting holes 31a and second mounting holes 31b, and the first mounting hole 31a is arranged farther away from the electrically conductive assembly 50 than the second mounting hole 31b. Among them, the first mounting hole 31a and the second mounting hole 31b are arranged in parallel at intervals. The distance between the second mounting hole 31b and the electrically conductive assembly 50 should not be too large, so as to shorten the length of the ground wire of the power supply line 51 connected to the grounding reinforcement 30, and at the same time make the structure arrangement more compact.

[0076] The assembly hole 11 is provided with two first assembly holes 11a and second assembly holes 11b, the first assembly hole 11a is arranged in position with the first mounting hole 31a, and the second assembly hole 11b is arranged in position with the second mounting hole 31b. The hole wall of the first assembly hole 11a and the hole wall of the second assembly hole 11b are both provided with electrically conductive fins 20.

[0077] The threaded hole 131 is provided with two first threaded holes 131a and second threaded holes 131b, the first threaded hole 131a is arranged in position with the first assembly hole 11a, and the second threaded hole 131b is arranged in position with the second assembly hole 11b.

[0078] The grounding connector 40 includes a first grounding screw 40a and a second grounding screw 40b, the first grounding screw 40a passes through the first mounting hole 31a and the first assembly hole 11a and is screwed into the first threaded hole 131a, the inside of the cabinet 10 is provided with a plurality of electrically conductive components, and the connecting lines of the plurality of electrically conductive components are connected to the grounding reinforcement 30 through the first grounding screw 40a; the second grounding screw 40b passes through the second mounting hole 31b and the second assembly hole 11b and is screwed into the second threaded hole 131b, the second grounding screw 40b is electrically connected with the grounding reinforcement 30 and the electrically conductive fin 20, and the electrically conductive assembly 50 is electrically connected with the second grounding screw 40b and the grounding reinforcement 30.

[0079] It is easy to understand that the first grounding screw 40a connects the connection lines of the plurality of conductive components inside the cabinet 10 to the grounding reinforcement 30, and plays a role of conducting the leakage generated by the conductive components inside the cabinet 10 to the grounding reinforcement 30. At the same time, the first grounding screw 40a is in electrical connection with the conductive fin 20 in the first assembly hole 11a, and can also conduct part of the leakage on the shell 12 to the grounding reinforcement 30.

[0080] Further, the shell 12 is in electrical connection with the second grounding screw 40b through the conductive fin 20 in the second assembly hole 11b, and can also conduct the leakage on the shell 12 to the grounding reinforcement 30, so that the leakage inside and outside the cabinet 10 is concentrated to the grounding reinforcement 30, and finally conducted to the ground through the conductive assembly 50, realizing the anti-electric shock design of the refrigerator 100 grounding.

[0081] Please continue to refer to Figure 1 and Figure 6 In an optional embodiment, the conductive assembly 50 includes a power cord 51 and a socket 52, the power cord 51 is arranged on the control panel box 13, and the ground wire of the power cord 51 is connected to the grounding reinforcement 30 through the second grounding screw 40b; the socket 52 is in electrical connection with the power cord 51, and the ground wire of the socket 52 is used to be connected to the ground.

[0082] In operation, the leakage conducted to the grounding reinforcement 30 penetrates into the power cord 51 through the ground wire of the power cord 51, then flows into the socket 52 along the power cord 51, and finally penetrates into the ground through the ground wire of the socket 52, realizing the grounding of the refrigerator 100. This grounding structure is simple in form, short in leakage conduction path, and high in efficiency of transmission into the ground, which helps to improve the anti-electric shock safety performance of the refrigerator 100.

[0083] Please continue to refer to Figure 2 and Figure 7 Further, the conductive assembly 50 further includes a fastener 53; the power cord 51 includes a cord body 511 and a seat body 512, the seat body 512 is connected with the cord body 511, the seat body 512 is arranged on the control panel box 13 through the fastener 53, and the control panel box 13 is provided with a limiting groove 132, and the seat body 512 is in limiting fit with the limiting groove 132.

[0084] For example, the fastener 53 can adopt a fastening screw, which is screwed and locked to fix the seat body 512 on the control panel box 13, improving the overall installation firmness of the power cord 51. Before threaded installation, the seat body 512 is clamped and fitted with the limiting groove 132, which can play a predetermined positioning effect on the power cord 51, prevent the power cord 51 from loosening, improve the alignment degree of the seat body 512 and the hole position on the control panel box 13, and facilitate the installation of the fastening screw.

[0085] Please continue to refer to Figure 2On the basis of the above-mentioned embodiments, the screw head of the first grounding screw 40a and the screw head of the second grounding screw 40b are both provided with a toothed gasket 80, which is limited to abut against the grounding reinforcement 30. A circle of teeth provided by the toothed gasket 80 engages the surface of the grounding reinforcement 30, thereby preventing the first grounding screw 40a and the second grounding screw 40b from loosening due to rotation, and improving the reliability of the installation of the first grounding screw 40a and the second grounding screw 40b.

[0086] Optionally, the toothed gasket 80 and the first grounding screw 40a and the second grounding screw 40b can be separately installed or can be of an integral structure, which can be flexibly selected according to actual needs.

[0087] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present application.

[0088] The above-mentioned embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
