Description

Technical Field

[0001] The utility model relates to a refrigerator. Background Art

[0002] In the past, as in the refrigerator described in Patent Document 1, a compressor machinery room formed of an integrally molded polypropylene material was generally used. However, the flame retardancy of polypropylene materials is relatively low and cannot meet the flame retardancy requirements. On the other hand, if 5VA materials are directly used for injection molding, the cost is high. Moreover, the compressor machinery room made of existing polypropylene materials is prone to deformation during the foaming operation. In addition, the machinery room has many related parts and poor versatility. Refrigerators of different models need to open molds separately to make the entire plastic base, and the cost of changes will be even higher. Therefore, the question that follows is how to strike a balance between flame retardancy and economy, ensure the higher flame retardancy of the compressor machinery room of the refrigerator and reduce manufacturing costs, while improving the strength and flatness of the compressor machinery room of the refrigerator.

[0004] Patent Literature

[0005] Patent Document 1: International Publication No. WO2009084181A1 Utility Model Content

[0006] The present utility model is completed based on the above-mentioned problems, and its purpose is to provide a device that takes into account both flame retardancy and economy, ensures high flame retardancy of the compressor mechanical room of the refrigerator and reduces manufacturing costs, while improving the strength and flatness of the compressor mechanical room of the refrigerator.

[0007] One aspect of the utility model provides a refrigerator having a compressor machine room for accommodating a compressor assembly. The compressor machine room includes a machine room injection-molded shell, and a machine room cladding sheet metal shell. The machine room injection-molded shell has two side surfaces extending in a first direction and a second direction, a bottom surface extending in a second direction and a third direction, and a back surface extending in a first direction and a third direction. The machine room cladding sheet metal shell has two side panels extending in a first direction and a second direction, a bottom panel extending in a second direction and a third direction, and a back panel extending in a first direction and a third direction. The machine room cladding sheet metal shell is detachably mounted on the outside of the machine room injection-molded shell.

[0008] In the refrigerator according to the utility model, optionally, the compressor machine room further comprises a machine room compressor reinforcement plate. The machine room compressor reinforcement plate is detachably mounted on the bottom of the machine room injection molded part housing.

[0009] In the refrigerator according to the utility model, since the mechanical room covering sheet metal shell is installed on the outside of the mechanical room injection molded part shell, and the mechanical room compressor reinforcement plate is installed on the bottom of the mechanical room injection molded part shell, the heat in the compressor mechanical room can be quickly conducted to the outside, thereby improving the overall heat dissipation of the compressor mechanical room. In addition, since the compressor mechanical room is supported by the mechanical room covering sheet metal shell and fixed by the mechanical room compressor reinforcement plate, when the compressor mechanical room is foamed, the deformation of the mechanical room injection molded part shell and the mechanical room covering sheet metal shell is effectively suppressed, which can greatly improve the overall flatness and strength of the compressor mechanical room.

[0010] In the refrigerator according to the utility model, optionally, the side, bottom and back of the machine room injection molded shell are formed integrally, the side panels, bottom panel and back panel of the machine room covering sheet metal shell are formed by the same sheet metal, and the machine room compressor reinforcement plate is formed by metal.

[0011] In the refrigerator according to the present invention, optionally, the inner surface of the sheet metal shell covering the machinery room is formed in a manner of being in close contact with the outer surface of the injection-molded shell of the machinery room to have substantially the same shape as the outer surface of the injection-molded shell of the machinery room.

[0012] Through such a structure, since the side plates, bottom plates, and back plates of the mechanical room covering sheet metal shell use the same sheet metal, they are processed into a shape that is roughly the same as the outer surface of the mechanical room injection molded shell, so that the mechanical room covering sheet metal shell is formed in a manner that is closely attached to the outer surface of the mechanical room injection molded shell. Since the flame retardancy of the sheet metal is relatively high and easy to form, the manufacturing and processing cost is relatively low, so it is possible to take into account both flame retardancy and economy, ensure the high flame retardancy of the compressor mechanical room of the refrigerator and reduce the manufacturing cost of the compressor mechanical room of the refrigerator. Therefore, the mechanical room covering sheet metal shell processed by sheet metal does not require additional separate mold opening operations, and can cope with the versatility of parts of different types of refrigerators. Therefore, the flame retardancy level of the compressor mechanical room can be increased to 5VA by simply covering the mechanical room injection molded shell with sheet metal. It has a good directional guidance for the upgrade of existing refrigerators and the corresponding investment savings in flame retardancy.

[0013] In the refrigerator according to the utility model, optionally, the side panels of the sheet metal shell covering the machinery room clamp the side surfaces of the injection molded shell of the machinery room in a manner that the inclination angle toward the bottom plate is less than 90 degrees.

[0014] With such a structure, since the inclination angle of the side panel of the sheet metal shell covering the mechanical room relative to the bottom plate is less than 90 degrees, that is, the side of the injection molded shell of the mechanical room is clamped in an inwardly buckled manner, the number of fixing screws used can be greatly reduced, thereby achieving the purpose of cost saving.

[0015] In the refrigerator according to the utility model, optionally, the side panels, bottom panel, and back panel of the sheet metal shell covering the machine room are formed with buckle portions respectively engaging with the side, bottom, and back surfaces of the injection molded shell of the machine room.

[0016] With such a structure, there is no need to use additional fixing screws, so that the machine room covering sheet metal shell can more closely cover the machine room injection molded shell, further improving the installation firmness of the machine room covering sheet metal shell relative to the machine room injection molded shell.

[0017] In the refrigerator according to the utility model, optionally, one or more first protrusions and at least one of the one or more second openings are formed on the machine room injection molded part shell, and one or more first openings and at least one of the one or more second protrusions are formed on the machine room covering sheet metal part shell at positions corresponding to the one or more first protrusions and the one or more second openings, and the positioning and connection of the machine room injection molded part shell and the machine room covering sheet metal part shell are achieved by engaging the one or more first protrusions with the one or more first openings, and engaging the one or more second openings with the one or more second protrusions. With such a structure, the connection between the machine room injection molded part shell and the machine room covering sheet metal part shell can be achieved by reducing the number of fixing screws used, thereby achieving the purpose of cost saving.

[0018] In the refrigerator according to the utility model, one or more third protrusions are optionally formed on the machine room injection molded part shell, one or more third openings are formed on the machine room covering sheet metal part shell at positions corresponding to the one or more third protrusions, and one or more fourth openings are formed on the machine room compressor reinforcement plate at positions corresponding to the one or more third protrusions and the one or more third openings. The one or more third protrusions are engaged with the one or more third openings and the one or more fourth openings to achieve positioning and connection of the machine room injection molded part shell, the machine room covering sheet metal part shell, and the machine room compressor reinforcement plate. With such a structure, the connection of the machine room injection molded part shell, the machine room covering sheet metal part shell, and the machine room compressor reinforcement plate can be achieved by reducing the number of fixing screws used, thereby achieving the purpose of cost saving.

[0019] In the refrigerator according to the utility model, optionally, one or more first columns are formed on the machine room injection molding shell, the first columns are penetrated in the first direction and protrude in the first direction, one or more fifth openings are formed on the machine room covering sheet metal shell at positions corresponding to the one or more first columns, one or more sixth openings are formed on the machine room compressor reinforcement plate at positions corresponding to the one or more first columns and the one or more fifth openings, and the compressor assembly passes through the one or more first columns and the one or more fifth openings and the one or more sixth openings through the gasket screws and rubber feet, and is screwed in the first direction to achieve the positioning and connection of the machine room injection molding shell and the machine room covering sheet metal shell and the machine room compressor reinforcement plate. Through such a structure, since the compressor machine room is supported by the machine room covering sheet metal shell and fixed by the machine room compressor reinforcement plate, the overall flatness and strength of the compressor machine room can be greatly improved.

[0020] In the refrigerator according to the utility model, the compressor mechanical room can optionally also accommodate a reactor assembly, a fan, a condenser, and a drying tube assembly. A plurality of slots are formed in the injection molded shell of the mechanical room, which are respectively arranged in one-to-one correspondence with the reactor assembly, the fan, the condenser, and the drying tube assembly. With such a structure, the compressor mechanical room of the refrigerator according to the utility model is formed.

[0021] Therefore, according to the refrigerator of the present invention, both flame retardancy and economy can be taken into account, ensuring the high flame retardancy of the compressor mechanical room of the refrigerator and reducing the manufacturing cost of the compressor mechanical room of the refrigerator, while improving the strength and flatness of the compressor mechanical room of the refrigerator.

DETAILED DESCRIPTION

[0040] The refrigerator of the present invention is described in detail below with reference to the accompanying drawings. In addition, in the description of the accompanying drawings, the same or corresponding parts are given the same reference numerals, and repeated descriptions are omitted.

[0041] In this specification, it should be understood that terms such as “includes,” “comprising,” and “having” refer to the existence of stated features, quantities, steps, operations, elements, parts, or a combination thereof, but do not exclude the existence of one or more other features, quantities, steps, operations, elements, parts, or a combination thereof.

The width direction of the compressor mechanical room of the refrigerator is set as the y direction, that is, the second direction D2. The length direction of the compressor mechanical room of the refrigerator is set as the x direction, that is, the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are substantially perpendicular to each other.

[0043] Figure 1 Schematically shows a cross-sectional view of the overall structure of the refrigerator 1 according to the utility model. Figure 1 As shown, the direction from the bottom of the refrigerator 1 to the top of the refrigerator 1 is the positive direction of the z direction. The direction from the front side of the refrigerator 1 to the back side of the refrigerator 1 is the positive direction of the y direction. In this embodiment, the refrigerator 1 is provided with a compressor machine room 10 at the back side of the top thereof, but the compressor machine room 10 may also be installed at other positions of the refrigerator 1.

[0044] Figure 2 1 is an exploded perspective view schematically showing a compressor machine room 10 according to the present invention.

[0045] The compressor machine room 10 includes a machine room injection molded part shell 11 , a machine room covering sheet metal part shell 12 , and a machine room compressor reinforcement plate 13 .

[0046] The machine room injection molded part housing 11 is formed as a cuboid having long sides in the x direction, and has two side surfaces extending in the z direction and the y direction, a bottom surface extending in the y direction and the x direction, and a back surface extending in the z direction and the x direction. The side surface, bottom surface and back surface of the machine room injection molded part housing 11 are formed integrally. In addition, the machine room injection molded part housing 11 is a semi-enclosed shell with a top surface in the z direction and a surface in the y direction as hollowed-out reference surfaces and a thickness of 2 mm retained. The machine room injection molded part housing 11 can be made of polypropylene material.

[0047] The mechanical room covering sheet metal shell 12 has two side plates extending in the z direction and the y direction, a bottom plate extending in the y direction and the x direction, and a back plate extending in the z direction and the x direction. The side plates, bottom plate, and back plate of the mechanical room covering sheet metal shell 12 are formed by the same sheet metal. The sheet metal can be a metal sheet with a thickness of 0.2 mm or more.

[0048] The machine room compressor reinforcement plate 13 is formed of metal. The thickness of the machine room compressor reinforcement plate 13 may be thicker than the thickness of the sheet metal member constituting the machine room cladding sheet metal member casing 12 .

[0049] The compressor machine room 10 contains a compressor assembly 20. The compressor assembly 20 is installed in a position slightly recessed toward the bottom for fixing the compressor assembly 20 in the bottom surface of the machine room injection molded part housing 11. In addition, the compressor machine room 10 also contains a fan 30, a condenser 40, a drying pipe assembly 50, and a reactor assembly 60. For details of the compressor assembly 20, the fan 30, the condenser 40, the drying pipe assembly 50, and the reactor assembly 60, refer to Figure 8 to Figure 12 The stereogram shown. A plurality of slots 120-123 are formed in the mechanical room injection molded part housing 11, and are respectively arranged one by one corresponding to the reactor assembly 60, the fan 30, the condenser 40, and the drying tube assembly 50 for their installation and fixation. Through such a structure, the fan 30 allows the airflow flowing in from the outside through the air inlet (not shown) to flow from the side of the condenser 40 to the side of the compressor assembly 20 in the compressor mechanical room 10, and then flows out from the air outlet (not shown) to the outside, thereby dissipating the heat of the compressor assembly 20.

[0050] The machine room covering sheet metal shell 12 is detachably mounted on the outside of the machine room injection molded shell 11. The machine room compressor reinforcement plate 13 is detachably mounted on the bottom of the machine room injection molded shell 11.

[0051] Figure 3 1 is a rear view schematically showing a compressor machine room 10 according to the present invention. Figure 4 FIG. 1 is a schematic rear perspective view of a compressor machine room 10 according to the present invention. Figure 3 and Figure 4As shown, the machine room compressor reinforcement plate 13 is installed at a position corresponding to the compressor assembly 20 in the bottom plate of the machine room covering sheet metal shell 12 .

[0052] In the refrigerator 1 according to the utility model, since the metal machine room covering sheet metal shell 12 is installed on the outside of the machine room injection molded part shell 11, and the metal machine room compressor reinforcing plate 13 is installed on the bottom of the machine room injection molded part shell 11, the heat in the compressor machine room 10 can be quickly conducted to the outside, thereby improving the overall heat dissipation of the compressor machine room 10. In addition, since the compressor machine room 10 is supported by the machine room covering sheet metal shell 12 and fixed by the machine room compressor reinforcing plate 13, when the compressor machine room 10 is foamed, the deformation of the machine room injection molded part shell 11 and the machine room covering sheet metal shell 12 is effectively suppressed, and the overall flatness and strength of the compressor machine room 10 can be greatly improved.

[0053] Figure 5 1 is a perspective view schematically showing a mechanical room covering sheet metal shell 12 according to the present invention. Figure 6 Schematically shows a perspective view of a machine room injection molded part housing 11 according to the present invention. Figure 7 1 is a perspective view schematically showing a machine room compressor reinforcement plate 13 according to the present invention.

[0054] The side plate, bottom plate, and back plate of the mechanical room covering sheet metal shell 12 are formed by the same sheet metal. Through sheet metal processing (such as stamping and bending), the inner surface of the mechanical room covering sheet metal shell 12 is formed in a shape that is roughly the same as the outer surface of the mechanical room injection molded shell 11 in a manner that is close to the outer surface of the mechanical room injection molded shell 11. Since the flame retardancy of sheet metal parts is relatively high and easy to form, the manufacturing and processing cost is relatively low, so it can take into account both flame retardancy and economy, ensure the high flame retardancy of the compressor mechanical room of the refrigerator and reduce the manufacturing cost of the compressor mechanical room of the refrigerator. Therefore, the mechanical room covering sheet metal shell 12 processed by sheet metal does not require additional separate mold opening operations, and can cope with the versatility of parts of different models of refrigerators. Therefore, by simply covering the mechanical room injection molded shell 11 with sheet metal, the flame retardancy level of the compressor mechanical room 10 can be increased to 5VA. There is a good directional guidance for the upgrade of existing refrigerators and the corresponding investment savings in flame retardancy.

[0055] Furthermore, in the refrigerator 1 according to the present invention, the side panels of the machine room covering sheet metal shell 12 can clamp the side surfaces of the machine room injection molded shell 11 at an inclination angle of 90 degrees or less toward the bottom plate.

[0056] With such a structure, since the inclination angle of the side panel of the sheet metal shell 12 covering the mechanical room relative to the bottom plate is less than 90 degrees, that is, the side of the injection molded shell 11 of the mechanical room is clamped in an inwardly buckled manner, the number of fixing screws used can be greatly reduced, thereby achieving the purpose of cost saving.

[0057] Similarly, the back plate of the sheet metal shell 12 covering the machine room can also clamp the back of the injection molded shell 11 of the machine room in a manner that the inclination angle to the bottom plate is less than 90 degrees. Compared with the above-mentioned method of only making the side plate of the sheet metal shell 12 covering the machine room at an inclination angle of less than 90 degrees relative to the bottom plate, by making the side plate and the back plate of the sheet metal shell 12 covering the machine room at an inclination angle of less than 90 degrees relative to the bottom plate, that is, clamping the side and back of the injection molded shell 11 of the machine room in an inward buckled manner, the number of fixing screws used can be further reduced, thereby achieving the purpose of cost saving. In addition, without the need for additional fixing screws, the sheet metal shell 12 covering the machine room can be made to cover the injection molded shell 11 of the machine room more closely, further improving the installation firmness of the sheet metal shell 12 covering the machine room relative to the injection molded shell 11 of the machine room.

[0058] In addition, if Figure 5 As shown, the side plates, bottom plate, and back plate of the mechanical room covering sheet metal shell 12 may also be formed with buckle parts 110 respectively engaging with the side, bottom, and back of the mechanical room injection molded shell 11. Thus, the mechanical room covering sheet metal shell 12 may be more closely covered with the mechanical room injection molded shell 11 without the need for additional fixing screws, further improving the installation firmness of the mechanical room covering sheet metal shell 12 relative to the mechanical room injection molded shell 11.

[0059] Next, the connection method of the machine room injection molded part housing 11, the machine room covering sheet metal housing 12, and the machine room compressor reinforcement plate 13 will be described.

[0060] like Figure 4 As shown, one or more protrusions 111 (in this embodiment, 3) are formed on the outer surface of the bottom surface and the back surface of the mechanical room injection molded part housing 11. In addition, one or more openings 113 (in this embodiment, 3) are formed on the back surface of the mechanical room injection molded part housing 11.

[0061] like Figure 5 As shown, one or more openings 116 are formed on the bottom plate and the back plate of the sheet metal shell 12 covering the machine room at positions corresponding to the one or more protrusions 111. In addition, one or more protrusions 117 are formed on the inner surface of the back plate of the sheet metal shell 12 covering the machine room at positions corresponding to the one or more openings 113.

[0062] Thus, the mechanical room injection molded part housing 11 and the mechanical room covering sheet metal housing 12 are positioned and connected by the engagement of the protrusion 111 with the opening 116 and / or the engagement of the opening 113 with the protrusion 117. By such a connection method, the mechanical room injection molded part housing 11 and the mechanical room covering sheet metal housing 12 can be connected by reducing the number of fixing screws, thereby achieving the purpose of cost saving.

[0063] In addition, if Figure 4 As shown, one or more protrusions 112 (four in this embodiment) are formed on the outer surface of the bottom surface of the machine room injection molded part housing 11.

[0064] like Figure 5 As shown, one or more openings 124 are formed on the bottom plate of the sheet metal housing 12 covering the machine room at positions corresponding to the one or more protrusions 112 .

[0065] like Figure 7 As shown, one or more openings 125 are formed in each of the machine room compressor reinforcing plates 13 at positions corresponding to the one or more protrusions 112 or the one or more openings 124 .

[0066] Thus, the mechanical room injection molded part housing 11, the mechanical room covering sheet metal housing 12 and the mechanical room compressor reinforcing plate 13 are positioned and connected by the engagement of the protrusion 112 with the openings 124 and 125. By such a connection method, the mechanical room injection molded part housing 11, the mechanical room covering sheet metal housing 12 and the mechanical room compressor reinforcing plate 13 can be connected by reducing the number of fixing screws used, thereby achieving the purpose of cost saving.

[0067] In addition, if Figure 6 As shown, one or more columns 118 (four in this embodiment) are formed on the inner surface of the bottom surface of the machine room molded part housing 11. The column 118 is a member that penetrates in the z direction and protrudes in the positive direction of the z direction.

[0068] like Figure 5 As shown, one or more openings 115 are formed on the bottom plate of the sheet metal housing 12 covering the mechanical room at positions corresponding to one or more columns 118 .

[0069] like Figure 4 and 7 As shown, one or more openings 114 are formed in each of the machine room compressor reinforcing plates 13 at positions corresponding to one or more pillars 118 or one or more openings 115 .

[0070] Fig.13It is a cross-sectional view schematically showing the connection method of the machine room injection molded part shell 11, the machine room cladding sheet metal part shell 12 and the machine room compressor reinforcement plate 13 according to the utility model.

[0071] Therefore, if Fig.13 As shown, the compressor assembly 20 is screwed in the z direction through the column 118 and the openings 114 and 115 via the gasket screws and rubber pads to achieve positioning and connection with the machine room injection molded part housing 11, the machine room sheathing sheet metal housing 12 and the machine room compressor reinforcement plate 13. In this connection method, the compressor assembly 20 is screwed to the machine room injection molded part housing 11 via the gasket screws and rubber pads, and the machine room sheathing sheet metal housing 12 and the machine room compressor reinforcement plate 13.

[0072] In addition, if Figure 6 As shown, one or more openings 200 (two in this embodiment) are formed on the bottom surface of the injection molded housing 11 of the machine room.

[0073] like Figure 5 As shown, one or more openings 119 are formed on the bottom plate of the sheet metal housing 12 covering the machine room at positions corresponding to the one or more openings 200 .

[0074] like Figure 7 As shown, one or more openings 201 are formed in each of the machine room compressor reinforcing plates 13 at positions corresponding to the one or more openings 200 or the one or more openings 119 .

[0075] Thus, the openings 119 , 200 , and 201 are connected by screwing in the z direction to achieve positioning and connection of the machine room injection molded part housing 11 , the machine room covering sheet metal part housing 12 , and the machine room compressor reinforcement plate 13 .

[0076] Next, the order of assembling the machine room injection molded part housing 11 , the machine room covering sheet metal housing 12 , and the machine room compressor reinforcing plate 13 will be described.

[0077] First, as described above, the machine room injection molded part shell 11, the machine room covering sheet metal part shell 12, and the machine room compressor reinforcement plate 13 are spliced ​​into one piece by means of buckles and screws. Then, the above components are installed on the top of the refrigerator 1 and foaming is performed. After the foaming is completed, the rubber feet (quantity 4) are inserted into the four protruding columns 118 of the machine room injection molded part shell 11, and then the compressor assembly 20 is installed, and finally the φ4*40 gasket screws (quantity 4) are screwed onto the machine room compressor reinforcement plate 13 through the four protruding columns 118 of the machine room injection molded part shell 11. Next, the reactor assembly 60 and the drying tube assembly 50 are respectively installed in the positions of the slots 120 and 123 on both sides. Then, the fan 30 and the condenser 40 are respectively installed in the positions of the slots 121 and 122 on the bottom surface. Thus, the compressor machine room 10 is formed.

[0078] In the compressor machinery room 10 formed in this way, since the flame retardancy of the sheet metal is relatively high and it is easy to form, the manufacturing and processing cost is relatively low, so it is possible to take into account both flame retardancy and economy, thereby ensuring the high flame retardancy of the compressor machinery room 10 of the refrigerator 1 and reducing the manufacturing cost of the compressor machinery room 10 of the refrigerator 1. In addition, the sheet metal shell 12 coated with the machinery room by sheet metal processing does not require additional separate mold opening operations, and can cope with the component commonality of refrigerators of different models. Therefore, by simply coating the injection molded shell 11 of the machinery room with sheet metal, the flame retardancy level of the compressor machinery room 10 can be increased to 5VA. It provides good directional guidance for the upgrade of existing refrigerators and the corresponding investment savings in flame retardancy. Furthermore, since the compressor mechanical room 10 is supported by the mechanical room covering sheet metal shell 12 and fixed by the mechanical room compressor reinforcement plate 13, when the compressor mechanical room 10 is foamed, the deformation of the mechanical room injection molding shell 11 and the mechanical room covering sheet metal shell 12 is effectively suppressed, which can greatly improve the overall flatness and strength of the compressor mechanical room 10.
