Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a refrigerator. Background Art

[0002] At present, the main control board box of the refrigerator is generally set on the top of the box body, which will occupy the height of the box body and reduce the volume of the refrigerator. Moreover, since the main control board box is on the top, the packaging cover of the refrigerator needs to avoid air, which may easily fail the stepping test. Increasing the thickness of the cover will lead to increased costs.

[0003] In the related art, the main control board box is chosen to be set in the middle position of the rear wall of the refrigerator. However, for the thermal insulation performance of the refrigerator, the foam layer between the inner tank and the main control board box needs to have a certain thickness. In this way, the inner tank needs to have a certain shape to avoid affecting the thickness of the air duct. The volume of the refrigerator is reduced, and the space required for the main control board box is relatively large. The width direction cannot be set too large, which is easy to block the foaming material. It can only be increased in the height direction. However, if the height direction is set too large, it will easily affect the air outlet position of the refrigeration air duct.

[0004] Therefore, it can be seen that how to reduce the occupation of the effective storage space inside the refrigerator and facilitate disassembly and assembly without affecting the setting of the refrigerator foaming layer and the air vent position has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0040] Combination Figure 1-7 As shown, the embodiment of the present disclosure provides a refrigerator comprising: a box body 100, a main control box body 200 and a main control box cover 300. The box body 100 is provided with a mounting opening 101 on the top of its rear side wall; the main control box body 200 is arranged on the side of the mounting opening 101 facing the inside of the box body 100, and the main control box body 200 is provided with an opening 201, and the opening 201 overlaps with the mounting opening 101; the main control box cover 300 detachably covers the side of the mounting opening 101 facing the outside of the box body 100.

[0041] The refrigerator provided by the embodiment of the present disclosure selects to set the main control box body 200 at the top of the rear wall of the box body 100, so that the main control box body 200 occupies the top rear side of the storage space in the refrigerator as much as possible. Since this part is located at a high position and deep inside the refrigerator, it is very inconvenient for users to access items at this position, so the utilization rate is relatively low, so that the impact of the main control box body 200 occupying this part of the space on user use is minimized, and the effective storage space inside the refrigerator is fully improved. The main control box body 200 is installed from the inside of the box body 100, and the main control box cover 300 is installed from the outside of the box body 100. This is not only convenient to install, but can also effectively improve the stability of the installation of the main control box body 200, and is also convenient for later maintenance and inspection of the inside of the main control box body 200.

[0042] Optionally, the box body 100 is provided with a folded edge 102 arranged around the installation opening 101, and the folded edge 102 is parallel to the rear side wall of the box body 100 and is recessed into the box body 100. In this way, the folded edge 102 arranged around the installation opening 101 is used to connect the main control box body 200 and the main control box cover 300 respectively, which can effectively improve the stability of the fixed connection between the two relative to the box body 100, wherein the recessed drop of the folded edge 102 relative to the box body 100 can effectively limit the main control box cover 300 to prevent the main control box cover 300 from shaking.

[0043] Optionally, the folded edge 102 and the box body 100 are an integral structure formed by sheet metal stamping. In this way, the structure formed by sheet metal stamping is low in cost, easy to produce, and has a stable structure. The folded edge 102 is formed by stamping to form a rib-like effect at its bending position, which can improve the overall structural strength of the box body 100.

[0044] Optionally, the distance that the folded edge 102 is sunken into the box body 100 is the same as the thickness of the main control box cover 300. In this way, the main control box cover 300 can be embedded in the area formed by the sunken side into the box body 100, so that the main control box cover 300 can be flush with the rear side wall of the box body 100 after installation, and the rear side wall of the refrigerator cannot be placed against the wall due to protrusion.

[0045] Combination Figure 2 As shown, optionally, one side of the main control box body 200 is connected to the side of the installation opening 101 through the plug-in structure 400, and the other side of the main control box body 200 is connected to the side wall of the box body 100 around the installation opening 101 through the anti-drop structure 500. In this way, one side of the main control box body 200 is connected to the side of the installation opening 101 through the plug-in structure 400, making its installation process faster and more convenient, and the other side is fixedly connected by the anti-drop structure 500, which can effectively improve the stability of the installation of the main control box body 200, prevent the main control box body 200 from falling off, and the whole is not fixed with screws, which improves the convenience of installation, reduces costs, and effectively improves the efficiency of production and assembly.

[0046] Optionally, the upper side of the main control box body 200 is connected to the side of the installation opening 101 through the plug structure 400, and the lower side of the main control box body 200 is connected to the side wall of the box body 100 around the installation opening 101 through the anti-drop structure 500. In this way, the lower side of the main control box body 200 is connected through the anti-drop structure 500, and since the lower side of the main control box body 200 is squeezed by the weight of the main control box body 200, the connection of the anti-drop structure 500 can be made more stable, further preventing the main control box body 200 from falling off.

[0047] Optionally, the plug-in structure 400 includes: a box body flange 202 and a claw 401. The box body flange 202 is arranged at the edge of the opening 201 of the main control box body 200 and is parallel to the plane where the opening 201 is located; the claw 401 is arranged on the box body flange 202, and a slot 402 is defined between its claw portion 404 and the box body flange 202, and the edge of the installation port 101 can be adapted to be inserted into the slot 402. In this way, the plug-in structure 400 uses the box body flange 202 and the claw 401 to cooperate with each other, and is directly clamped on the edge of the installation port 101, without setting other structures on the sheet metal at the edge of the installation port 101, and the structure is simple, easy to produce, and the production cost is effectively reduced.

[0048] Combination Figure 6 As shown, optionally, the claw 401 includes a connecting portion 403 and a claw portion 404, the connecting portion 403 is vertically connected to the box body flange 202, and the claw portion 404 is vertically arranged at one end of the connecting portion 403. In this way, the claw portion 404 can be parallel to the box body flange 202, and the gap between the claw portion 404 and the side edge of the installation opening 101 is used to engage with each other, so that the main control box body 200 is more stably installed at the installation opening 101.

[0049] Optionally, the claw 401 and the box body flange 202 are an integral structure, and the claw 401 is formed by stamping the box body flange 202. In this way, the stability between the claw 401 and the box body flange 202 of the integral structure is higher, and the stamping is directly adopted, which is low in cost, convenient in production, effectively reducing costs and improving production efficiency.

[0050] Optionally, the height of the box body flange 202 protruding relative to the edge of the opening 201 of the main control box body 200 is greater than the length of the claw portion 404 of the claw 401, wherein the length of the claw portion 404 refers to the length of the claw portion 404 in the protruding direction of the box body flange 202. In this way, the box body flange 202 can better abut against the folded edge 102 of the installation opening 101, thereby improving the tightness of the connection between the main control box body 200 and the installation opening 101.

[0051] Combination Figure 2-3 As shown, optionally, the anti-falling structure 500 includes: a connecting column 501 and a connecting hole 502. The connecting column 501 is arranged on the main control box body 200; the connecting hole 502 is arranged on the side wall of the box body 100 around the installation opening 101, and a folding claw 503 facing the outside of the box body 100 is arranged in the connecting hole 502. In this way, the connecting column 501 arranged on the main control box body 200 is directly passed through the connecting hole 502 arranged on the side wall of the box body 100, so that the two are fixed to each other, and the installation structure is simple and convenient, and the folding claw 503 is arranged in the connecting hole 502, and the folding claw 503 is used to squeeze the connecting column 501, thereby increasing the friction force on the connecting column 501, making the connection between the connecting column 501 and the connecting hole 502 more stable, and effectively preventing the main control box body 200 from falling off.

[0052] Optionally, the connecting column 501 is arranged on the box body flange 202 of the main control box body 200. In this way, the box body flange 202 of the main control box body 200 is connected to the folded edge 102 of the installation opening 101, and its connection position is more reasonably utilized to reduce the occupation of other positions.

[0053] Optionally, the diameter of the free end of the connecting column 501 is larger than the diameter of the end thereof connected to the main control box body 200. In this way, after the connecting column 501 is inserted into the connecting hole 502, the relatively large diameter of the free end of the connecting column 501 can prevent the connecting column 501 from falling off from the connecting hole 502, thereby improving the stability of the connection between the two, and thus effectively improving the anti-falling effect of the main control box body 200.

[0054] Optionally, the diameter of the connecting column 501 gradually increases from the end connected to the main control box body 200 to the free end. In this way, the diameter of the connecting column 501 gradually increases toward the free end, which can keep the outer wall of the connecting column 501 smooth, and when the connecting column 501 is pressed hard, the connecting column 501 can be separated from the connecting hole 502, thereby facilitating the disassembly of the main control box body 200 in some cases, and improving its flexibility of use.

[0055] Optionally, the folding claw 503 in the connection hole 502 is an integral structure with the box body 100 and is formed by sheet metal stamping. In this way, the connection hole 502 and the folding claw 503 are directly formed by stamping, the production process is simple and convenient, the cost is lower, and the structural stability is better.

[0056] Optionally, the folding direction of the folding claw 503 is from the inside of the box 100 to the outside of the box 100. In this way, the connecting column 501 can be inserted from the inside of the box 100 to the outside of the box 100 along the folding direction of the folding claw 503, making it easier to insert. On the contrary, when the connecting column 501 is pulled out to the inside of the box 100, a large friction force is generated between the tip of the folding claw 503, preventing the connecting column 501 from falling off by itself, thereby improving the anti-falling effect of the connecting column 501 and the connecting hole 502 after being assembled.

[0057] Combination Figure 7 As shown, optionally, the positions where the main control box body 200 and the installation opening 101 are connected through the plug-in structure 400 and the anti-drop-off structure 500 are provided with connection positions 600 recessed toward the inside of the box body 100. In this way, the connection positions 600 recessed toward the inside of the box body 100 are provided at the positions of the edge of the installation opening 101 corresponding to the plug-in structure 400 and the anti-drop-off structure 500, which can prevent the plug-in structure 400 and the anti-drop-off structure 500 from protruding and affecting the installation of the main control box cover 300, and maintain the tightness of the connection between the main control box cover 300 and the edge of the installation opening 101.

[0058] Optionally, the connection position 600 includes an inclined slot corresponding to the plug-in structure 400 and an installation groove corresponding to the anti-drop structure 500. The inclined slot is arranged on the edge of the fold 102, and the claw 401 can be directly inserted into the inclined slot through the edge of the fold 102. The installation groove is also arranged on the fold 102, but does not extend to the edge of the fold 102. In this way, the claw 401 can be directly inserted into the inclined slot along the edge of the fold 102, which is more convenient for assembly, and the installation groove does not extend to the edge of the fold 102, so that it forms a complete groove shape on the fold 102, and the overall structural stability is higher, thereby improving the structural strength of the position of the connection hole 502 and improving the stability of the connection between the connection column 501 and the connection hole 502.

[0059] Optionally, the edge of the box body flange 202 is folded toward the free end of the connecting column 501, and the distance of the abutting edge 203 protruding relative to the box body flange 202 is the same as the distance of the concave connection position 600. In this way, the abutting edge 203 on the box body flange 202 can bypass the connection position 600 and directly abut against the folded edge 102 of the box body 100, thereby improving the tightness of the connection between the main control box body 200 and the box body 100, ensuring the closure of the main control box body 200, and at the same time reducing the shaking of the main control box body 200 and improving its stability.

[0060] Optionally, the installation opening 101 is arranged at the middle position of the top of the rear side wall of the box body 100, and has a set distance from the left and right side walls of the box body 100. In this way, the main control box body 200 can be installed at the middle position of the top of the rear side wall of the box body 100, and has a set distance from the left and right side walls, so as to avoid occupying the foam filling layer in the left and right side walls of the box body 100 and prevent affecting the heat preservation effect of the box body 100.

[0061] Optionally, an inner liner is provided inside the box 100, and the distance is set greater than the distance between the side wall of the box 100 and the inner liner. In this way, the installation of the main control box 200 can be prevented from affecting the filling of the foam layer between the box 100 and the inner liner, thereby improving the overall thermal insulation performance.

[0062] Optionally, one side of the main control box cover 300 is plugged into the box body 100, and the other side is fixedly connected to the box body 100 by screws. In this way, the main control box cover 300 can be more conveniently connected to the box body 100, improving the convenience of installation and ensuring the stability of the connection between the two.

[0063] Optionally, a jack is provided on the concave wall of the folded edge 102 of the installation opening 101 that is concave inwardly relative to the box body 100, and an insert is provided on the main control box cover 300, and the insert corresponds to the position of the jack and can be inserted into the jack. In this way, the jack is provided on the concave wall of the folded edge 102 that is concave inwardly relative to the box body 100, so that the insert can be directly inserted into the jack vertically, thereby improving the convenience of connection between the two and making it easier to install the main control box cover 300.

[0064] Optionally, both the main control box body 200 and the main control box cover 300 are covered with a heat preservation layer. In this way, the heat preservation effect of the installation position of the main control box body 200 can be improved, and frost or condensation caused by the excessively low temperature of the main control box body 200 can be avoided.

[0065] Optionally, a sealing ring is provided around the inner side of the main control box cover 300. In this way, the sealing effect of the main control box cover 300 on the main control box body 200 can be maintained, and condensation caused by airflow entering the main control box body 200 can be avoided, thereby affecting the service life of the main control box body 200.

[0066] Optionally, the size of the main control box cover 300 is the same as the size of the outline of the connection between the folded edge 102 and the box body 100. In this way, the main control box cover 300 can be just embedded in the outline of the connection between the folded edge 102 and the box body 100, reducing the gap between the two and improving the sealing effect inside the main control box cover 300.

[0067] Combination Figure 8 As shown, optionally, a top storage area 103 corresponding to the height of the main control box body 200 is provided at the top of the box body 100. In this way, the top storage area 103 is provided at the top of the box body 100, and a separate area is made for the part of the space occupied by the main control box body 200. Since the height of this part is relatively high and the user's frequency of use is relatively low, this part of the area is separately isolated for storing some small items that are not often used, which does not affect the overall user experience.
