[0073] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0074] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a refrigerator that can reduce the risk of damage to the refrigerator back panel while allowing the refrigerator back to fit more closely against the wall.

[0075] The following is for reference. Figures 1-9 Refrigerator 1 according to an embodiment of this application is described.

[0076] like Figure 1 As shown, the refrigerator 1 includes: an outer shell 10, an inner liner, an insulation layer, and a compressor. The outer shell 10 includes a top plate 110, a side plate 120, a back plate 130, and a bottom plate 140. The outer shell 10 forms a compressor compartment 20. The inner liner is installed inside the outer shell 10 to form a compartment. The insulation layer is formed between the outer shell 10 and the inner liner. The compressor is installed in the compressor compartment 20.

[0077] The outer shell 10 can be composed of a top plate 110, a side plate 120, a back plate 130 and a bottom plate 140. The main function of the outer shell 10 is to provide support and physical protection for the internal structure of the refrigerator 1.

[0078] The inner liner is the internal storage space of the refrigerator 1, usually made of materials such as plastic or stainless steel. The inner liner is installed inside the outer shell 10 to form a compartment. The compartment is mainly used to provide storage space for items and to store different types of items through a reasonable layout.

[0079] For example, the inner liner may be equipped with partitions or drawers to divide the compartments for easy classification and management of items.

[0080] The gap between the outer shell 10 and the inner liner can serve as the installation space for the insulation layer. The insulation layer is usually made of polyurethane foam or other high-efficiency heat insulation materials to reduce the heat exchange between the inside of the refrigerator 1 and the external environment, enhance the heat preservation effect of the refrigerator 1, and thus improve the energy efficiency of the refrigerator 1.

[0081] The outer casing 10 also forms a compressor compartment 20, which is mainly used to house components such as the compressor that generate noise during operation, and effectively isolates noise to maintain the low-noise operation of the refrigerator 1.

[0082] The compressor is the core component of the refrigerator 1 refrigeration system. It is usually installed in the compressor compartment 20. The compressor regulates the internal temperature of the refrigerator 1 by continuously compressing and releasing the refrigerant. Specifically, the compressor is mainly used to compress the refrigerant and deliver it to the condenser through the refrigeration system. Then the refrigerant is delivered from the condenser to the evaporator, where it releases heat and lowers the internal temperature of the refrigerator 1.

[0083] The refrigeration system of refrigerator 1 relies on the operation of the compressor. When the compressor is working, it generates heat. A heat dissipation vent connected to the compressor compartment 20 is provided on the outer shell 10 of refrigerator 1 to help the heat in the compressor compartment 20 dissipate quickly.

[0084] Specifically, at least one of the top plate 110, side plate 120 and bottom plate 140 adjacent to the compressor compartment 20 is provided with a heat dissipation vent that connects to the compressor compartment 20. That is, the heat dissipation vent can be located at at least one of the top, side and bottom of the refrigerator 1. The heat dissipation vent can connect the compressor compartment 20 to the outside, so that the hot air in the compressor compartment 20 can be quickly released to the outside through the heat dissipation vent, thereby reducing the risk of excessive temperature in the compressor area and maintaining the efficient operation of the compressor.

[0085] It should be noted that designing the heat dissipation vents in a position adjacent to the compressor compartment 20, rather than the traditional rear, allows for better utilization of the refrigerator 1's spatial layout and reduces the limitations of traditional rear air outlets.

[0086] In addition, the bottom of the outer shell 10 of the refrigerator 1 is recessed forward at the back to form a relief groove 150. The relief groove 150 is open at the back, sides and bottom, which can provide suitable placement space for components such as baseboards, thereby optimizing the spatial layout of the back of the refrigerator 1 and reducing the gap between the back of the refrigerator 1 and the wall.

[0087] Specifically, the clearance groove 150 is a recessed area on the back of the refrigerator 1. Its shape and size can be designed according to actual needs. The clearance groove 150 runs through the side of the refrigerator 1 and is open at the back and bottom. The baseboard is usually closely connected to the wall and located at the back of the refrigerator 1. Setting the clearance groove 150 at the rear of the refrigerator 1 can provide appropriate space for components such as the baseboard, thereby reducing the occupation of extra space.

[0088] Meanwhile, the rear surface of the side plate 120 protrudes rearward relative to the rear surface of the back plate 130, which can reduce the contact between the back plate 130 and the wall, thereby reducing the wear on the back plate 130. It can also reduce the molding difficulty of the side plate 120 and improve the interface strength between the side plate 120 and the back plate 130.

[0089] When refrigerator 1 is installed indoors, it is usually placed against a wall or in a corner. The refrigeration system of refrigerator 1 relies on the operation of a compressor, which generates heat during operation. Therefore, a heat dissipation vent is usually installed on the compressor compartment 20 of refrigerator 1. However, during interior decoration, baseboards are usually installed at the junction of the floor and the wall. Furthermore, refrigerator 1 in related technologies typically has a rear-exhaust system, resulting in a large gap between the back of refrigerator 1 and the wall. This gap easily accumulates dust, making cleaning difficult and potentially creating hygiene hazards, thus affecting the user experience and indicating room for improvement.

[0090] This application provides an clearance groove 150 on the back of the refrigerator 1 to provide appropriate installation space for components such as baseboards. This can reduce unnecessary gaps between the refrigerator 1 and the wall, allowing the back of the refrigerator 1 to fit more tightly against the wall, which helps reduce hygiene hazards and also reduces the tilting or shaking of the refrigerator 1 due to instability.

[0091] According to the refrigerator 1 provided in the embodiment of this application, by providing an avoidance groove 150 on the back of the refrigerator 1, unnecessary gaps between the refrigerator 1 and the wall can be reduced, making the back of the refrigerator 1 fit more tightly against the wall. At the same time, the rear end of the side panel 120 protrudes backward relative to the back panel 130, which can reduce the contact between the back panel 130 and the wall, thereby reducing the risk of damage to the back panel 130 due to friction.

[0092] In some embodiments, such as Figure 3 and Figure 4 As shown, the side panel 120 includes a side panel body 122 and a bent structure 190 connected to the rear end of the side panel body 122. The side panel body 122 and the bent structure 190 form a first groove 123 that opens forward and a second groove 124 that opens backward. The first groove 123 is located on the lateral outer side of the second groove 124. The back panel 130 is installed in the second groove 124. The bottom of the first groove 123 protrudes backward relative to the back panel 130.

[0093] Specifically, the side panel 120 includes a side panel body 122 and a bending structure 190 connected to the rear end of the side panel body 122. The side panel body 122 is a panel located on the side of the refrigerator 1. The bending structure 190 is located on the side of the side panel body 122 facing the inside of the refrigerator 1. The bending structure 190 includes multiple folded edges connected in sequence. The side panel body 122 and the bending structure 190 together form a first groove 123 and a second groove 124. The first groove 123 opens forward and the second groove 124 opens backward. That is, the first groove 123 communicates with the inside of the refrigerator 1 and the second groove 124 communicates with the external environment.

[0094] The inner side of the side panel body 122 is the groove wall of the first groove 123. That is, the first groove 123 is located between the side panel body 122 and the second groove 124 in a direction perpendicular to the side panel body 122. The second groove 124 is formed between multiple folds of the bent structure 190 and is mainly used to install the back panel 130 and firmly connect the back panel 130 and the side panel 120 together.

[0095] In addition, the bottom of the first groove 123 protrudes 2mm behind the back panel 130, that is, when the back of the refrigerator 1 is against the wall, the outer side of the bottom of the first groove 123 contacts the wall, and a gap is formed between the back panel 130 and the wall, thereby protecting the back panel 130.

[0096] The bending structure 190 can also improve the structural strength of the connection. At the same time, the bending structure 190 and the back plate 130 are connected by a fitting method, which can reduce the use of additional fasteners and thus improve the sealing of the joint.

[0097] It should be noted that in related technologies, there are also side panels that are formed to connect with the back panel through a bending process. However, in conventional refrigerators, the bent part of the side panel extends along the height direction. When installing the refrigerator, the space occupied is increased due to the need to avoid the baseboard, and a gap is formed between the refrigerator and the wall. Therefore, conventional refrigerators strive to make the bent part of the side panel flush with the back panel to reduce the space occupied. The bottom of the refrigerator 1 of this application is recessed forward at the back to form an avoidance groove 150, which cooperates with the bending structure 190 of the side panel 120 to reduce the space occupied, while covering the gap formed between the back panel 130 of the refrigerator 1 and the wall.

[0098] Understandably, the second groove 124 formed by the bending structure 190 of the side panel 120 and the back panel 130 is installed on the side panel 120, which can reduce the risk of the connection between the back panel 130 and the side panel 120 being exposed to the outside, thereby reducing the risk of the back panel 130 falling off or shifting during use.

[0099] In some embodiments, such as Figure 4 As shown, the bending structure 190 includes a first to a fourth folded edge 194 connected in sequence. The end of the first folded edge 191 facing away from the second folded edge 192 is connected to the side plate body 122, and the second folded edge 192 is disposed opposite to the side plate body 122. The side plate body 122, the first folded edge 191 and the second folded edge 192 form a first groove 123, and the second folded edge 192, the third folded edge 193 and the fourth folded edge 194 form a second groove 124. The first folded edge 191 protrudes rearward relative to the back plate 130.

[0100] The side panel body 122, the first folded edge 191, and the second folded edge 192 together form the first groove 123, wherein the side panel body 122 and the second folded edge 192 form the side wall of the first groove 123, the first folded edge 191 forms the bottom wall of the first groove 123, and the first groove 123 faces the interior of the refrigerator 1.

[0101] For example, the first folded edge 191 can be a U-shaped structure. One end of the first folded edge 191 away from the second folded edge 192 is connected to the side panel body 122, and the other end of the first folded edge 191 is connected to the second folded edge 192. The second folded edge 192 is disposed opposite to the side panel body 122 and is parallel to the side panel body 122.

[0102] The second fold 192, the third fold 193 and the fourth fold 194 form the second groove 124, wherein the second fold 192 and the fourth fold 194 form the sidewalls of the second groove 124, the third fold 193 forms the bottom wall of the second groove 124, and the second groove 124 faces the outside of the refrigerator 1.

[0103] For example, the third fold 193 can be an arc-shaped structure. One end of the third fold 193 away from the fourth fold 194 is connected to the second fold 192, and the other end of the third fold 193 is connected to the fourth fold 194. From the end of the fourth fold 194 connected to the third fold 193 to the other end of the fourth fold 194, the sidewall of the second groove 124 formed by the fourth fold 194 gradually approaches the second fold 192.

[0104] In addition, the first folded edge 191 protrudes rearward relative to the back panel 130, and the first folded edge 191 forms the bottom wall of the first groove 123. That is, when the back of the refrigerator 1 abuts against the wall, the outer side of the bottom wall of the first groove 123 contacts the wall, and a gap is formed between the back panel 130 and the wall, thereby protecting the back panel 130.

[0105] It is understood that the bending structure 190 includes multiple sequentially connected folds, which can increase the strength of the bending structure 190 while forming a structure for mounting the back plate 130, thereby increasing the connection strength between the back plate 130 and the side plate 120.

[0106] In some embodiments, such as Figure 5 As shown, the back panel 130 has a forward-folding back panel fold 131 on its side, and the back panel fold 131 has a protruding rib 132. The back panel fold 131 extends into the second groove 124 and is engaged with the second groove 124 by the protruding rib 132.

[0107] The second fold 192, the third fold 193, and the fourth fold 194 of the side panel 120 form a second groove 124, wherein the second fold 192 and the fourth fold 194 form the side wall of the second groove 124, the third fold 193 forms the bottom wall of the second groove 124, the second groove 124 faces the outside of the refrigerator 1, the back panel 130 is installed in the second groove 124, and the fourth fold 194 is located on the side of the back panel 130 facing the inside of the refrigerator 1.

[0108] For example, the side of the back panel 130 may be provided with a back panel folded edge 131 that folds inward into the refrigerator 1, and the opening of the second groove 124 faces outward from the refrigerator 1. The back panel folded edge 131 extends into the second groove 124 and is locked in place, thereby realizing the connection between the back panel 130 and the side panel 120.

[0109] In addition, the back panel folded edge 131 is provided with a protruding rib 132, and the back panel folded edge 131 extends into the second groove 124 and is engaged with the second groove 124 through the protruding rib 132.

[0110] Specifically, the back panel fold 131 is perpendicular to the other parts of the back panel 130. The protruding rib 132 on the back panel fold 131 faces the fourth fold 194, and the fourth fold 194 is inclined toward the second fold 192, forming a second groove 124 with a groove width smaller than the bottom of the groove. When the back panel fold 131 extends into the second groove 124, the protruding rib 132 on the back panel fold 131 abuts against the inclined fourth fold 194, thereby forming a snap-fit ​​structure between the back panel 130 and the side panel 120.

[0111] It is understandable that the back panel 130 is engaged with the second groove 124 formed by the back panel 131 with the back panel folded edge 132 and the side panel 120, thereby achieving a firm connection between the back panel 130 and the side panel 120.

[0112] In some embodiments, such as Figure 5 As shown, the bending structure 190 also includes a fifth and a sixth fold 196, the first to the sixth folds 196 are connected in sequence, and the end of the sixth fold 196 away from the fifth fold 195 abuts against the fourth fold 194.

[0113] The bending structure 190 may also include a fifth fold 195 and a sixth fold 196 connected in sequence, with the fifth fold 195 connected between the fourth fold 194 and the sixth fold 196, wherein one end of the fourth fold 194 is connected to the third fold 193 and the other end is connected to the fifth fold 195.

[0114] Specifically, the fourth fold 194 forms the sidewall of the second groove 124, and the fourth fold 194 is inclined. From the end connected to the third fold 193 to the end connected to the fifth fold 195, the vertical distance between the fourth fold 194 and the second fold 192 gradually decreases. At the same time, the end of the fourth fold 194 connected to the fifth fold 195 and the second fold 192 together form the opening of the second groove 124.

[0115] Furthermore, the end of the sixth fold 196 away from the fifth fold 195 abuts against the fourth fold 194. Specifically, the fifth fold 195 can be an arc-shaped structure, and the sixth fold 196 is inclined. From the end connected to the fifth fold 195 to the end away from the fifth fold 195, the vertical distance between the sixth fold 196 and the fourth fold 194 and the second fold 192 gradually decreases until the end of the sixth fold 196 away from the fifth fold 195 contacts the fourth fold 194.

[0116] For example, the fourth fold 194, the fifth fold 195 and the sixth fold 196 together form a teardrop-shaped structure, which can improve the strength of the bending structure 190 and improve the sealing performance at the connection between the back plate 130 and the side plate 120, thereby reducing the risk of material overflow at the connection between the back plate 130 and the side plate 120.

[0117] Understandably, the end of the sixth fold 196 that is away from the fifth fold 195 abuts against the fourth fold 194, which can reduce the risk of material overflow at the connection between the back plate 130 and the side plate 120.

[0118] In some embodiments, such as Figure 1 As shown, the back panel 130 is provided with a reinforcing structure 160, which is recessed toward the opening of the refrigerator 1.

[0119] In this embodiment, certain portions of the back panel 130 of the refrigerator 1 are recessed toward the interior of the refrigerator 1 to form a reinforcing structure 160. For example, the reinforcing structure 160 can be a groove or a protrusion. The recessed area is formed by stamping. The shape of the recess can include vertical strips and circles, etc. At the same time, the reinforcing structures 160 are spaced apart to increase the mechanical strength of the back panel 130.

[0120] The reinforcing structure 160 can improve the overall strength of the back panel 130 without increasing its thickness, thereby reducing deformation or damage caused by uneven stress or external impact. The reinforcing structure 160 on the back panel 130 is recessed towards the inside of the refrigerator 1, which can optimize the spatial layout of the back panel 130 of the refrigerator 1, thereby reducing the gap between the back panel 130 of the refrigerator 1 and the wall, and helping the majority of the back panel 130 to abut against the wall.

[0121] Understandably, the back panel 130 is provided with a reinforcing structure 160 and is recessed forward, which can combine the dual advantages of structural enhancement and space optimization, thereby improving the overall strength and stability of the outer shell 10 and effectively optimizing the external space layout of the refrigerator 1.

[0122] In some embodiments, such as Figure 1 and Figure 6 As shown, the compressor compartment 20 is formed at the bottom of the outer casing 10, and the heat dissipation vents are provided in at least one of the side plate 120 and the bottom plate 140. The outer casing 10 also includes a compressor compartment rear cover 250 installed behind the compressor compartment 20. The compressor compartment rear cover 250 is bent to form a relief groove 150. The compressor compartment rear cover 250 is provided with a connecting structure 170 connected to the structural components of the refrigerator 1. The connecting structure 170 is recessed toward the opening direction of the refrigerator 1.

[0123] Specifically, the compressor compartment 20 can be formed at the bottom of the outer casing 10. The compressor compartment 20 is mainly used to accommodate components that generate noise during operation, such as the compressor, and effectively isolate noise to maintain the low-noise operation of the refrigerator 1. Specifically, the outer casing 10 also includes a compressor compartment rear cover 250 installed behind the compressor compartment 20. The compressor compartment front cover, compressor compartment rear cover 250 and bottom plate 140 together form the compressor compartment 20 located at the bottom of the refrigerator 1. The compressor compartment rear cover 250 and the back plate 130 are both located at the back of the refrigerator 1. The compressor compartment rear cover 250 is located below the back plate 130, and the bottom plate 140 is located at the bottom of the refrigerator 1. The compressor compartment front cover is connected between the compressor compartment rear cover 250 and the bottom plate 140.

[0124] At least one of the side plate 120 and bottom plate 140 of the outer casing 10 is provided with a heat dissipation vent, which is connected to the compressor chamber 20. The compressor chamber rear cover 250 of the outer casing 10 is installed at the rear of the compressor chamber 20 and is recessed forward at the lower part to form a relief groove 150. The relief groove 150 is open at the back, side and bottom.

[0125] Specifically, at least one of the side panels 120 and bottom panels 140 of the outer casing 10 adjacent to the compressor compartment 20 is provided with a heat dissipation vent. That is, the heat dissipation vent can be located at least one of the side and bottom of the refrigerator 1. The heat dissipation vent can connect the compressor compartment 20 with the outside, so that the hot air in the compressor compartment 20 can be quickly released to the outside through the heat dissipation vent, thereby reducing the risk of excessive temperature in the compressor area and maintaining the efficient operation of the compressor.

[0126] The compressor compartment rear cover 250 of the outer casing 10 is installed at the rear of the compressor compartment 20, and is recessed forward at the bottom to form a relief groove 150. The relief groove 150 is open at the back, side and bottom, which can provide suitable placement space for components such as baseboards, thereby optimizing the spatial layout of the back of the refrigerator 1 and reducing the gap between the back of the refrigerator 1 and the wall.

[0127] The elastic decorative piece is installed on the outer side of the compressor compartment rear cover 250 in the left-right direction and is located at the clearance groove 150. It can provide additional support and decoration. At the same time, the elastic decorative piece protrudes backward relative to the compressor compartment rear cover 250 in the non-compressed state, which can be used to protect the back plate 130 and reduce the impact of external forces on the back plate 130. The elastic decorative piece can also cover the corners of the back and outer side of the mounting piece 220 to reduce the wear of the corners.

[0128] For example, resilient decorative elements may include components with elastic deformation capabilities, typically made of flexible materials such as rubber, plastic, and silicone.

[0129] Understandably, the resilient trim can absorb external impacts or pressures, helping the compressor compartment rear cover 250 to resist the effects of external forces to some extent.

[0130] In addition, the compressor compartment rear cover 250 is provided with a connecting structure 170 that is connected to the structural components of the refrigerator 1, and the connecting structure 170 is recessed forward.

[0131] The connecting structure 170 is the connection part between the compressor compartment rear cover 250 and the structural component of the refrigerator 1. Through the connecting structure 170, the compressor compartment rear cover 250 can be more firmly combined with the structural component of the refrigerator 1, and the structural component forms the compressor compartment 20.

[0132] For example, the connection structure 170 typically uses bolts, clips, welding or plug-in to fix the compressor compartment rear cover 250 to other important components of the refrigerator 1 in order to maintain the stability of the refrigerator 1 during use.

[0133] For example, the connection structure 170 may include a first connection structure 171 and a second connection structure 172. When the compressor chamber 20 is at the bottom, the compressor chamber rear cover 250 and the bottom plate 140 are connected by the first connection structure 171, and the compressor chamber rear cover 250 and the bottom support beam 230 of the compressor chamber 20 are connected by the second connection structure 172. When the compressor chamber 20 is at the top, the compressor chamber rear cover 250 and the top plate 110 are connected by the first connection structure 171, and the compressor chamber rear cover 250 and the bottom support beam 230 of the compressor chamber 20 are connected by the second connection structure 172.

[0134] The connecting structure 170 is recessed into the refrigerator 1 to form a certain concave structure. This allows the connecting structure 170 to be embedded into the interior of the refrigerator 1 or into the surface depth of the compressor compartment rear cover 250 without increasing the external space occupied, which helps to enhance the connection strength between the compressor compartment rear cover 250 and the structural components.

[0135] In some embodiments, such as Figure 6 As shown, when the compressor compartment 20 is formed at the bottom of the outer casing 10, the connection structure 170 can be at least one of the following structural forms:

[0136] Firstly, the connection structure 170 may include a first connection structure 171.

[0137] In this embodiment, the first connecting structure 171 may include a forward-protruding buckle, and the buckle engages with a hook on the bottom plate flange 141 of the bottom plate 140 of the housing 10.

[0138] Specifically, the second connection structure 172 may include a buckle provided on the rear cover 250 of the compressor compartment. The buckle protrudes into the refrigerator 1 and is used to engage with a hook. A gap is formed between the buckle and other parts of the rear cover 250 of the compressor compartment. The hook extends into the gap from one side of the buckle, and the end of the hook abuts against a part of the rear cover 250 of the compressor compartment located on the other side of the buckle, thereby forming a stable connection.

[0139] It should be noted that after the hook is engaged with the second connecting structure 172, the hook does not protrude from the compressor compartment rear cover 250.

[0140] For example, the buckle can engage with the hook on the bottom plate flange 141 of the bottom plate 140 of the housing 10, thereby achieving a secure connection between the bottom plate 140 and the press chamber rear cover 250.

[0141] Secondly, the connection structure 170 may include a second connection structure 172.

[0142] In this embodiment, the second connection structure 172 may include a recessed groove provided on the rear cover 250 of the compressor chamber, the groove being recessed forward, and the bottom of the groove having a connection hole.

[0143] For example, the second connecting structure 172 can be used to cooperate with the threaded connector. The second connecting structure 172 protrudes into the refrigerator 1 to form a recessed groove, and the bottom of the recessed groove is provided with a connecting hole to form a concave threaded interface. The threaded connector can pass through the connecting hole to penetrate the compressor compartment rear cover 250, and after installation, the threaded connector does not protrude from the compressor compartment rear cover 250.

[0144] It should be noted that the second connecting structure 172 near the upper edge of the rear cover 250 of the compressor compartment is connected to the back plate 130, the second connecting structure 172 near the lower edge of the rear cover 250 of the compressor compartment is connected to the bottom plate flange 141 of the bottom plate 140, and the second connecting structure 172 near the lower corner of the rear cover 250 of the compressor compartment is connected to the bottom plate flange 141 of the bottom plate 140 and the bottom support beam 230.

[0145] For example, the connecting hole can be, but is not limited to, a slotted hole, to reduce the requirements for machining accuracy and assembly accuracy.

[0146] Third, the connection structure 170 may include a first connection structure 171 and a second connection structure 172.

[0147] In this embodiment, the connecting structure 170 may include a first connecting structure 171 and a second connecting structure 172. The first connecting structure 171 includes a forward-protruding buckle that engages with a hook on the bottom plate flange 141 of the bottom plate 140 of the outer casing 10. The second connecting structure 172 includes a recessed groove provided in the rear cover 250 of the compressor chamber. The groove is recessed forward and the bottom of the groove is provided with a connecting hole.

[0148] Specifically, the first connection structure 171 may include a buckle provided on the rear cover 250 of the compressor compartment. The buckle protrudes into the refrigerator 1 and is used to engage with a hook. A gap is formed between the buckle and other parts of the rear cover 250 of the compressor compartment. The hook extends into the gap from one side of the buckle, and the end of the hook abuts against a part of the rear cover 250 of the compressor compartment located on the other side of the buckle, thereby forming a stable connection.

[0149] It should be noted that after the hook is engaged with the first connecting structure 171, the hook does not protrude from the rear cover 250 of the compressor compartment.

[0150] For example, the buckle can engage with the hook on the bottom plate flange 141 of the bottom plate 140 of the housing 10, thereby achieving a secure connection between the bottom plate 140 and the press chamber rear cover 250.

[0151] For example, the second connecting structure 172 can be used to cooperate with the threaded connector. The second connecting structure 172 protrudes into the refrigerator 1 to form a recessed groove, and the bottom of the recessed groove is provided with a connecting hole to form a concave threaded interface. The threaded connector can pass through the connecting hole to penetrate the compressor compartment rear cover 250, and after installation, the threaded connector does not protrude from the compressor compartment rear cover 250.

[0152] It should be noted that the second connecting structure 172 near the upper edge of the rear cover 250 of the compressor compartment is connected to the back plate 130, the second connecting structure 172 near the lower edge of the rear cover 250 of the compressor compartment is connected to the bottom plate flange 141 of the bottom plate 140, and the second connecting structure 172 near the lower corner of the rear cover 250 of the compressor compartment is connected to the bottom plate flange 141 of the bottom plate 140 and the bottom support beam 230.

[0153] It is understandable that by cooperating with different connection structures 170, the external space occupied by the back plate 130 and the compressor compartment rear cover 250 can be reduced.

[0154] In some embodiments, such as Figure 1 and Figure 7As shown, the compressor compartment 20 is formed at the bottom of the outer casing 10, and the heat dissipation vents are provided in at least one of the side plate 120 and the bottom plate 140. The outer casing 10 also includes a compressor compartment rear cover 250 installed behind the compressor compartment 20. The compressor compartment rear cover 250 includes a rear cover first part 251, a rear cover second part 252 and a rear cover third part 253 connected sequentially from top to bottom. The rear cover first part 251 and the rear cover third part 253 are respectively bent with the rear cover second part 252. The rear cover second part 252 forms at least a portion of the top wall of the clearance groove 150. The rear cover third part 253 is connected to the rear end of the bottom plate 140 and forms at least a portion of the front wall of the clearance groove 150.

[0155] In this embodiment, the compressor compartment rear cover 250 is connected between the back plate 130 and the bottom plate 140. Both the compressor compartment rear cover 250 and the back plate 130 are located at the back of the refrigerator 1. The compressor compartment rear cover 250 is located below the back plate 130, and the bottom plate 140 is located at the bottom of the refrigerator 1. The compressor compartment rear cover 250 includes a first rear cover portion 251, a second rear cover portion 252, and a third rear cover portion 253 connected sequentially from top to bottom. The first rear cover portion 251 is connected between the lower end of the back plate 130 and the second rear cover portion 252. The second rear cover portion 252 is connected between the first rear cover portion 251 and the third rear cover portion 253. The third rear cover portion 253 is connected between the second rear cover portion 252 and the rear end of the bottom plate 140.

[0156] In addition, the first part 251 and the third part 253 of the rear cover are bent into shape with the second part 252 of the rear cover. Specifically, the first part 251 and the third part 253 of the rear cover are parallel to the back panel 130, the second part 252 of the rear cover is perpendicular to the first part 251 and the third part 253 of the rear cover, and the third part 253 of the rear cover is closer to the inside of the refrigerator 1 than the first part 251 of the rear cover.

[0157] It should be noted that the compressor compartment rear cover 250 is recessed forward at the bottom to form a clearance groove 150, the second part 252 of the rear cover forms at least a portion of the top wall of the clearance groove 150, and the third part 253 of the rear cover forms at least a portion of the front wall of the clearance groove 150.

[0158] In some embodiments, such as Figure 8 and Figure 9 As shown, the bottom of the side panel 120 has a notch 121 at the rear end, and the second part 252 and the third part 253 of the rear cover are both arranged in the notch 121 to form a clearance groove 150.

[0159] In this embodiment, the notch 121 at the bottom rear end of the side panel 120 makes the area at the bottom of the side panel 120 not completely closed, thereby forming a certain space. The second part 252 and the third part 253 of the rear cover are arranged in the notch 121 to form a relief groove 150, which is open at the back, side and bottom.

[0160] Specifically, the bottom of the side panel 120 has an L-shaped notch 121 at the rear end, the second part 252 of the rear cover is parallel to the bottom plate 140 to form the top wall of the clearance groove 150, and the third part 253 of the rear cover is parallel to the back plate 130 to form the side wall of the clearance groove 150.

[0161] Understandably, the second part 252 and the third part 253 of the rear cover are arranged at the notch 121 at the bottom of the side panel 120, which can make full use of the space at the bottom of the refrigerator 1, so that the bottom area is not limited to a straight line and closed design, thereby improving the operability of the refrigerator 1.

[0162] In some embodiments, such as Figure 9 As shown, the upper edge of the notch 121 is higher than the second part 252 of the back cover, so as to form a wiring channel 210 between the upper edge of the notch 121 and the second part 252 of the back cover.

[0163] In this embodiment, the second part 252 of the rear cover is parallel to the bottom plate 140, forming the top wall of the clearance groove 150. The top wall of the clearance groove 150 is located below the upper edge of the notch 121 and is spaced apart from the upper edge of the notch 121. A wiring channel 210 is formed between the upper edge of the notch 121 and the second part 252 of the rear cover.

[0164] The wiring channel 210 is a channel designed inside the refrigerator 1 for placing and guiding electrical components such as cables or wires. The wiring channel 210 is located above the top wall of the clearance groove 150 and can provide an orderly and safe path, allowing the cables inside the refrigerator 1 to be led out from the wiring channel 210 and safely transmitted to the outside of the refrigerator 1 to connect to power sources or external devices, reducing interference between cables and other components inside the refrigerator 1.

[0165] Understandably, the upper edge of the notch 121 is higher than the second part 252 of the back cover, which can form a wiring channel 210.

[0166] In some embodiments, such as Figure 9 As shown, the upper edge of the notch 121 is higher than the second part 252 of the back cover, so as to form a wiring channel 210 between the upper edge of the notch 121 and the second part 252 of the back cover.

[0167] In this embodiment, the second part 252 of the rear cover is parallel to the bottom plate 140, forming the top wall of the clearance groove 150. The top wall of the clearance groove 150 is located below the upper edge of the notch 121 and is spaced apart from the upper edge of the notch 121. A wiring channel 210 is formed between the upper edge of the notch 121 and the second part 252 of the rear cover.

[0168] The wiring channel 210 is a channel designed inside the refrigerator 1 for placing and guiding electrical components such as cables or wires. The wiring channel 210 is located above the top wall of the clearance groove 150 and can provide an orderly and safe path, allowing the cables inside the refrigerator 1 to be led out from the wiring channel 210 and safely transmitted to the outside of the refrigerator 1 to connect to power sources or external devices, reducing interference between cables and other components inside the refrigerator 1.

[0169] Understandably, the upper edge of the notch 121 is higher than the second part 252 of the back cover, which can form a wiring channel 210.

[0170] In some embodiments, such as Figure 6 As shown, the refrigerator 1 also includes a mounting piece 220, which is installed at the notch 121, and the third part 253 of the rear cover is installed on the back of the mounting piece 220.

[0171] In this embodiment, the mounting component 220 is the main component in the refrigerator 1 structure used to form the compressor compartment 20. The mounting component 220, together with the back plate 130 and the bottom plate 140 in the outer shell 10 of the refrigerator 1, forms the compressor compartment 20 that accommodates the compressor.

[0172] Specifically, the mounting component 220 is installed at the bottom of the side panel 120 at the notch 121 at the rear end, and cooperates with the side panel 120 to form the side of the refrigerator 1. At the same time, the third part 253 of the rear cover of the compressor compartment rear cover 250 is installed on the back of the mounting component 220, that is, on the side of the mounting component 220 facing the back panel 130.

[0173] Understandably, the third part 253 of the back cover is installed on the back of the mounting piece 220, which can reduce the possibility of the back panel 130 loosening or deforming due to long-term use or external force.

[0174] In some embodiments, such as Figure 6 and Figure 7 As shown, the rear end of the base plate 140 has an upwardly folded base plate flange 141, and the bottom of the refrigerator 1 is provided with a bottom support beam 230. The back plate 130, the base plate flange 141 and the bottom support beam 230 overlap sequentially from back to front and are connected in the overlapping area. The mounting component 220 is provided with a clearance opening for avoiding the base plate flange 141.

[0175] In this embodiment, the bottom plate flange 141 is located at the rear end of the bottom plate 140 of the refrigerator 1 and is folded upward. The bottom plate flange 141 has a certain angle or shape, which is used to connect the bottom plate 140 with other structures. It can also enhance the bending resistance of the bottom plate 140 and reduce the deformation of the bottom plate 140 caused by the refrigerator 1 bearing heavy objects or long-term use.

[0176] For example, the back plate 130, the bottom plate flange 141, and the bottom support beam 230 can overlap in various ways, such as the back plate 130, the bottom plate flange 141, and the bottom support beam 230 overlapping sequentially from back to front, or the bottom plate flange 141, the back plate 131, and the bottom support beam 230 overlapping sequentially from back to front.

[0177] The back panel 130, the bottom plate flange 141, and the bottom support beam 230 have overlapping areas and are connected in the overlapping areas, which can improve the overall stability and strength of the refrigerator 1. At the same time, the overlapping connection can provide additional structural support, so that the back panel 130, the bottom plate flange 141, and the support beam can share the external forces on the refrigerator 1, further enhancing the load-bearing capacity and stability of the bottom of the refrigerator 1.

[0178] For example, the back plate 130 and the bottom plate flange 141 can be connected by a snap-fit ​​structure, and the back plate 130, the bottom plate flange 141 and the bottom support beam 230 can be connected by a threaded connection structure 170 in the overlapping area.

[0179] In addition, the mounting component 220 is provided with a clearance opening, which is mainly used to avoid the bottom plate flange 141, thereby minimizing the interference area between the mounting component 220 and the bottom plate flange 141. The back plate 130, the bottom plate flange 141 and the bottom support beam 230 overlap sequentially from back to front in the overlapping area, and the overlapping area is provided with a threaded connection structure 170. At the same time, the clearance opening of the mounting component 220 is also located in the overlapping area.

[0180] It is understandable that by setting the clearance opening, the mounting part 220 can be installed without interfering with the bottom plate flange 141, which helps the mounting part 220 to be installed smoothly without affecting the function or structure of the bottom plate flange 141, and can effectively improve the stability and load-bearing capacity of the bottom of the refrigerator 1.

[0181] In some embodiments, such as Figure 9 As shown, a side panel folded edge 180 is provided at the notch 121. The side panel folded edge 180 includes a first section 181 that folds inward and a second section 182 that folds backward. The outer front end of the mounting member 220 has a protruding part 226 that protrudes forward. The front surface of the protruding part 226 is arranged opposite to the first section 181 in the front-back direction. The inner side of the protruding part 226 is arranged opposite to the second section 182 in the left-right direction, and the second section 182 is located inside the protruding part 226.

[0182] In this embodiment, the bottom of the side panel 120 has a notch 121 at the rear end, and the side panel folding edge 180 is a folding structure formed by folding the edge portion at the notch 121 of the side panel 120 at a certain angle.

[0183] The side panel folded edge 180 includes a first segment 181 and a second segment 182 that are perpendicular to each other. The first segment 181 folds inward toward the side panel 120 and is parallel to the back panel 130. The first segment 181 can strengthen the side panel 120. The second segment 182 folds backward and is parallel to the side panel 120. The second segment 182 is used to connect with the mounting piece 220 and can enhance the firmness of the structural connection.

[0184] The front outer side of the mounting component 220 has a forward-protruding protrusion 226, which is mainly used to provide additional support points or connection points to help the mounting component 220 be fixedly connected to the side panel folded edge 180.

[0185] Specifically, the front surface of the protrusion 226 and the first segment 181 of the side panel folded edge 180 are both parallel to the back panel 130, and the front surface of the protrusion 226 and the first segment 181 of the side panel folded edge 180 are arranged opposite each other in the front-rear direction, wherein the first segment 181 of the side panel folded edge 180 is located in front of the front surface of the protrusion 226, and the protrusion 226 abuts against the first segment 181 of the side panel folded edge 180.

[0186] The inner side of the protrusion 226 and the second segment 182 of the side plate folded edge 180 are both parallel to the side plate 120, and the inner side of the protrusion 226 and the second segment 182 of the side plate folded edge 180 are arranged opposite each other in the left and right direction. The second segment 182 of the side plate folded edge 180 is located inside the protrusion 226 and abuts against the protrusion 226.

[0187] That is, the side panel folded edge 180 covers the front surface and inner side surface of the protrusion 226, thereby achieving a stable fit between the side panel folded edge 180 and the protrusion 226. At the same time, the side panel folded edge 180 can get additional support, reducing the risk of deformation of the side panel folded edge 180 due to external forces.

[0188] Furthermore, the relative arrangement of the protrusion 226 and the side panel folded edge 180 facilitates precise installation, reduces errors during installation, and improves assembly accuracy and efficiency.

[0189] It is understandable that by providing a side panel folded edge 180 at the notch 121 and combining the side panel folded edge 180 with the protrusion 226 of the mounting part 220, the installation process can be optimized and the connection between the refrigerator 1 outer shell 10 and the mounting part 220 can be strengthened.

[0190] In some embodiments, the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is ΔH1, which satisfies: ΔH1≤150mm.

[0191] In this embodiment, the bottom of the outer shell 10 of the refrigerator 1 is recessed forward at the rear end to form a relief groove 150. The relief groove 150 is open at the back, side and bottom, which can provide suitable placement space for components such as baseboards, thereby optimizing the spatial layout of the back of the refrigerator 1 and reducing the gap between the back of the refrigerator 1 and the wall.

[0192] Specifically, the clearance groove 150 is the area that is recessed forward at the rear end of the refrigerator 1. The clearance groove 150 runs through the side of the refrigerator 1 and is open at the back and bottom. The baseboard is usually installed at the back of the refrigerator 1 and is tightly connected to the wall. Setting the clearance groove 150 at the rear end of the refrigerator 1 can provide appropriate space for components such as the baseboard, thereby reducing the occupation of extra space.

[0193] The cross-section of the clearance groove 150 along the direction perpendicular to the side panel 120 of the refrigerator 1 is an inverted L-shape. The vertical distance ΔH1 from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is the length of the clearance groove 150 along the height direction of the back panel 130, and the size range of ΔH1 is 120mm to 150mm.

[0194] For example, when the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is too small, such as ΔH1<120mm, the clearance groove 150 will not match the baseboard, thus making it impossible to install the refrigerator 1.

[0195] For example, when the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is too large, such as ΔH1>150mm, space will be wasted and the overall capacity utilization of the refrigerator 1 will be affected.

[0196] Understandably, setting the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 within a certain size range can give the refrigerator 1 enough space to accommodate the internal components while reducing the occupation of extra space.

[0197] In some embodiments, the height of the refrigerator 1 is H, the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is ΔH1, the horizontal dimension of the clearance groove 150 is a, the line connecting the vertex of the refrigerator 1 near the wall and the vertex of the clearance groove 150 near the opening of the refrigerator 1 is defined as the back tilt reference line, the angle between the back tilt reference line and the vertical direction is defined as the back tilt reference angle, the back tilt reference angle is α, tanα=a / (H-ΔH1), satisfying: 0.1°≤α≤1.5°.

[0198] In related technologies, most refrigerators are not mounted against the wall, making it difficult to judge the severity of the refrigerator's tilt by the gap between the refrigerator and the wall. This application uses whether the refrigerator is mounted against the wall as the basis for adjusting the adjustable feet 30. That is, by adjusting the adjustable feet 30 until the top of the refrigerator 1 is mounted against the wall, the degree of backward tilt of the refrigerator 1 is reduced while achieving the state where the refrigerator 1 is mounted against the wall in different installation scenarios.

[0199] It should be noted that when the top of refrigerator 1 is against the wall, refrigerator 1 may actually be in a vertical position or tilted backward.

[0200] In this embodiment, the height of the refrigerator 1 is H, the vertical distance from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is ΔH1, the length of the top wall of the clearance groove 150 in the front-back direction is a, and the line connecting the top of the back of the refrigerator 1 near the wall and the top of the clearance groove 150 near the opening of the refrigerator 1 is defined as the back tilt reference line.

[0201] When the back of refrigerator 1 is against the wall and refrigerator 1 is in a vertical position, the angle between the tilt reference line and the vertical direction is defined as the tilt reference angle. At this time, the angle between the tilt reference line and the outer surface of the back of refrigerator 1 is equal to the tilt reference angle α.

[0202] When the back of refrigerator 1 is against the wall and refrigerator 1 is tilted backward, the angle between the tilt reference line and the vertical direction is defined as the tilt reference angle. At this time, the angle between the tilt reference line and the outer surface of the back of refrigerator 1 is less than the tilt reference angle α.

[0203] For example, taking an under-sink refrigerator as an example, when the height H of the refrigerator 1 is 0.9m, the vertical distance ΔH1 from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is 150mm, and the horizontal dimension a of the clearance groove 150 is 14mm, tanα is 0.018, and the back tilt reference angle α is 1.1°.

[0204] For example, taking a conventional refrigerator as an example, when the height H of the refrigerator 1 is 1.6m, the vertical distance ΔH1 from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is 150mm, and the horizontal dimension a of the clearance groove 150 is 14mm, tanα is 0.01, and the back tilt reference angle α is 0.6°.

[0205] For example, taking a conventional refrigerator as an example, when the height H of the refrigerator 1 is 1.8m, the vertical distance ΔH1 from the top wall of the clearance groove 150 to the bottom surface of the refrigerator 1 is 120mm, and the horizontal dimension a of the clearance groove 150 is 14mm, tanα is 0.008, and the back tilt reference angle α is 0.45°.

[0206] It is understandable that by controlling the backward tilt reference angle α within a certain range, the backward tilt of refrigerator 1 can be reduced, thereby reducing the risk of severe tilting of refrigerator 1.
