Description

Technical Field

[0001] This application relates to the field of refrigeration, and more specifically to a freezer. Background Technology

[0002] The door of a horizontal freezer is connected to the cabinet via hinges, enabling opening, closing, hovering, and shutting down. Traditional hinges are fixed at one end to the back of the door with screws, and the other end is fixed to the cabinet via mounting holes in the back panel. To accommodate the door's flip-up design, the hinge itself needs a certain volume. Typically, after installation, the hinge protrudes awkwardly outside the cabinet, adding extra dimensions to the freezer, increasing packaging space, reducing the actual load during assembly and transportation, and increasing production costs. Utility Model Content

[0003] To address the aforementioned issues, this application provides a freezer that solves the problem of the rear hinge protruding beyond the freezer body.

[0004] This application provides a freezer, including a cabinet, a door, and at least one hinge. The cabinet has an opening, and the door includes a rear wall connected to the cabinet.

[0010] Furthermore, the upper edge of the mounting cavity is lower than the highest point of the rear wall, and the lower edge of the mounting cavity is higher than the lowest point of the rear wall.

[0011] Furthermore, the height of the mounting cavity in the vertical direction is the same as the thickness of the door body, and the dimension of the mounting cavity in the length direction of the rear wall is smaller than the length of the rear wall.

[0012] Furthermore, the lower surface of the convex edge is connected to the recessed wall to form an L-shaped structure.

[0013] Furthermore, the protruding edge also includes an outer side surface that connects to the lower surface, the outer side surface coinciding with the extension surface of the rear panel of the housing.

[0014] Furthermore, the protruding edge also includes an outer side surface that connects to the lower surface, the outer side surface being parallel to the extension surface of the rear panel of the housing.

[0015] Furthermore, the second hinge seat includes a second connecting portion, which is connected to the door body and is located in the mounting cavity.

[0016] Furthermore, the first hinge seat includes a first connecting portion that protrudes from the mounting cavity and extends downward to connect to the first surface.

[0017] Furthermore, the first hinge seat includes a first hinge portion tangentially connected to the first connecting portion, and the second hinge seat includes a second hinge portion pivotally connected to the first hinge portion to form the pivot portion. The second hinge portion has a vertical planar structure, and the planar structure is flush with the outer wall of the first connecting portion.

[0018] Furthermore, the second connecting portion includes a first reinforcing rib surrounding its edge, and the second connecting portion also includes at least one elongated first fixing hole, wherein the first reinforcing rib is provided with an arc-shaped placement portion in the length extension direction of the first fixing hole.

[0019] Furthermore, the second hinge seat passes through the lower surface of the door and connects to the side of the rear wall facing the front end of the freezer.

[0020] This application relates to a refrigerator, including a cabinet, a door, and at least one hinge. The door is openable and closeable at an opening via the hinge. The hinge includes a first hinge seat and a second hinge seat, which are rotatably connected via a pivot. The first hinge seat is connected to a first surface of the rear panel of the cabinet, and the second hinge seat is connected to a second surface of the rear wall of the door. The first and second surfaces are not parallel. By making the first surface connecting the first hinge seat and the second surface connecting the second hinge seat parallel, this application reduces the size of the hinge protruding from the cabinet, increases the actual load capacity during assembly and transportation, and effectively reduces actual production costs.

[0050] To provide a better understanding of the purpose, structure, features, and functions of this application, detailed descriptions are provided below with reference to specific embodiments.

[0051] This application provides a freezer 100, including a cabinet 1, a door 2, and at least one hinge 3. The cabinet 1 has an opening, and the door 2 includes a rear wall 24, which is connected to the cabinet 1 via the hinge 3. The door 2 can be opened and closed to cover the opening. The cabinet 1 has a first surface disposed on a back panel 11, and the rear wall 24 includes a second surface. The hinge 3 includes a first hinge seat 31 and a second hinge seat 32, which are rotatably connected via a pivot 33. The first hinge seat 31 is connected to the first surface of the cabinet 1, and the second hinge seat 32 is connected to the second surface of the door 2. The first surface and the second surface are not parallel.

[0052] In this application, the first surface is the side wall of the back panel 11 away from the front end of the freezer 100. The front end of the freezer 100 is the side where the user takes or puts items from the freezer 100. Alternatively, the rear end of the freezer 100 is the end of the freezer 100 where the hinge is located. The front end of the freezer 100 is positioned opposite to the rear end of the freezer 100.

[0053] The second surface is located on the rear wall 24 and is used to fix the second hinge seat 32.

[0054] The first surface and the second surface are not parallel, which means that the extension surfaces of the first surface and the second surface are parallel but do not coincide, or that the extension surfaces of the first surface and the second surface partially intersect.

[0055] The top of the freezer body 100 is provided with an opening for taking out and putting in items. The opening can be rectangular. The door 2 covers the opening and can be freely rotated by the hinge 3 pivot 33 to open and close the opening of the body 1.

[0056] In one embodiment, the door 2 includes a mounting cavity 4 for accommodating a portion of the hinge 3. The mounting cavity 4 is recessed relative to the extension surface of the rear panel 11 of the cabinet 1. Specifically, the mounting cavity 4 extends recessed relative to the front end of the cabinet 100. The rear wall 24 of the door 2 is partially recessed relative to the extension surface of the rear panel 11 of the cabinet 1 by stamping or injection molding to form the mounting cavity 4. That is, the depth of the recess in the mounting cavity 4 is referenced to the plane where the rear panel 11 of the cabinet 1 is located.

[0057] The hinge 3 includes a first hinge seat 31 and a second hinge seat 32 that are pivotally connected to each other. The first hinge seat 31 is fixed to the edge of the opening of the housing 1 or to the back panel 11; the second hinge seat 32 is fixed to the rear side of the door 2. The first hinge seat 31 and the second hinge seat 32 are rotatably connected by a pivot part 33, wherein the axial direction of the pivot part 33 is consistent with the rotation axis of the door 2 opening and closing. In this application, the axial direction of the pivot part 33 is horizontal.

[0058] The pivot portion 33 may be partially located in the mounting cavity 4. Alternatively, the axis of the pivot portion 33 may be completely placed inside the mounting cavity 4, or the axis of the pivot portion 33 may be located on the reference plane, or the axis of the pivot portion 33 may be located outside the mounting cavity 4.

[0059] In this application, the axis of the pivot 33 can be completely placed inside the mounting cavity 4. The axis of the pivot 33 is completely enclosed by the mounting cavity 4 and communicates with the outside only through the opening of the mounting cavity 4. That is, the height of the axis of the pivot 33 is higher than the height of the upper edge of the box 1, and the axis is closer to the center of the door 2 than the reference plane in the depth direction of the mounting cavity 4.

[0060] By placing part of the pivot section 33 in the mounting cavity 4, the overall external dimensions of the freezer 100 can be reduced, the space required for packaging can be reduced, the container capacity during transportation can be increased, and thus production costs can be reduced.

[0061] The door body 2 includes a front wall 21 and a rear wall 24 disposed opposite to each other; the rear wall 24 includes a protruding edge 23 at its upper end and protruding away from the front end of the freezer and a recessed wall 22 at its lower end and recessed towards the front end of the freezer. The lower surface of the protruding edge 23 is connected to the recessed wall 22 and forms an installation cavity 4. The recessed wall 22 is a second surface for installing the second hinge seat 32.

[0062] Specifically, the front wall 21 of the door 2 is the side of the door 2 that is closer to the user when the door 2 is covered by the opening of the cabinet 1. That is, the front wall 21 of the door 2 is the opening side of the door 2, and the front wall 21 is located at the front end of the freezer; the rear wall 24 is arranged opposite to the front wall 21 along the width direction of the door 2.

[0063] The protruding edge 23 is located at the top edge of the rear wall 24 and protrudes away from the front wall 21 or away from the front end of the freezer. The lower surface of the protruding edge 23 is directly connected to the top edge of the recessed wall 22, forming a recessed mounting cavity 4. The recessed wall 22 is a vertical plane, which constitutes the vertical sidewall of the mounting cavity 4 and serves as the second surface for the fixed connection of the second hinge seat. Specifically, the mounting cavity 4 is a semi-enclosed space used to accommodate part of the hinge 3. The second hinge seat 32 of the hinge 3 is fixedly connected to the recessed wall 22.

[0064] In the first embodiment, the lower surface of the convex edge 23 is connected to the recessed wall 22 to form an L-shaped structure.

[0065] The protruding edge 23 is configured as a plate-like structure extending horizontally away from the front wall 21. Below it is a lower surface 231, which is a flat portion and connects perpendicularly or approximately perpendicularly to the upper end of the recessed wall 22. That is, the corner where the lower surface 231 of the protruding edge meets the upper end of the recessed wall 22 is a right angle or a slightly rounded transition, forming a cross-sectional structure similar to a "┌" shape. The horizontal portion of the L-shaped structure is the protruding edge 23, and the vertical portion is the recessed wall 22, together enclosing the space of the mounting cavity 4.

[0066] Alternatively, the protruding edge 23 and the recessed wall 22 are integrally formed. The protruding edge 23 can be considered as a structure formed by bending the top of the recessed wall 22 of the door body 2 in a direction away from the front wall 21.

[0067] Of course, the protruding edge 23 can also be manufactured as a plate structure, and the protruding edge 23 and the recessed wall 22 are fixedly connected by welding, bonding, riveting and other methods.

[0068] In the second embodiment, the lower surface 231 of the protruding edge can be a curved surface. Specifically, the lower surface 231 of the protruding edge can be a continuous curved surface, such as a circular arc surface, a parabolic surface, or a composite curved surface, and this application does not impose any specific limitations.

[0069] The protruding edge 23 also includes an outer side surface that connects to the lower surface 231 of the protruding edge, and the outer side surface is flush with the back panel 11 of the housing 1.

[0070] The outer surface 232 of the protruding edge is a vertical surface that connects to the far end of the lower surface 231 of the protruding edge. Specifically, the outer surface 232 of the protruding edge is connected to the end of the lower surface 231 of the protruding edge away from the recessed wall 22. The connection point is a right angle or a slightly rounded transition, forming a cross-sectional structure similar to "┘".

[0071] When the door 2 is in the state of closing the opening of the box 1, the outer side 232 of the protruding edge is coplanar and flush with the rear panel 11 of the box 1 in the vertical direction. That is, when the door 2 is in the state of closing the opening of the box 1, the outer side 232 of the protruding edge coincides with or is coplanar with the extension surface of the rear panel 11 of the box 1.

[0072] In other alternative embodiments, the height of the outer surface 232 of the flange extending in the vertical direction is greater than or equal to 0. That is, the flange 23 can be formed directly from the lower surface 231 of the flange in a direction away from the front wall 21 and upward.

[0073] When the door 2 is closed, the outer side 232 of the protruding edge is completely flush with the back panel 11 of the cabinet 1 in the vertical direction, which can effectively prevent dust and other objects from entering the mounting cavity 4 and interfering with the rotation of the hinge 3, ensuring that the hinge 3 can rotate reliably for a long time; at the same time, it makes the freezer 100 product present an integrated visual effect.

[0074] In the first and second embodiments described above, the recessed wall 22 is parallel to and does not intersect with the first surface. Specifically, the recessed wall 22 is closer to the front end of the freezer than the first surface. By setting the first surface connecting the first hinge seat 31 and the second surface connecting the second hinge seat 32 as non-convex surfaces, the size of the hinge 3 protruding outside the cabinet 1 is reduced, increasing the actual load / cabinet capacity during assembly and transportation, and effectively reducing actual production costs.

[0075] Of course, in the first embodiment, the protruding edge 23 includes an outer side surface that connects the lower surface 231 of the protruding edge 23. The plane on which the outer side surface is located is parallel to and does not coincide with the extension surface of the rear back panel 11 of the box body 1. That is, the plane on which the outer side surface is located is closer to the interior of the box body 1 than the rear back panel 11, or the plane on which the outer side surface is located is farther away from the interior of the box body 1 than the rear back panel 11.

[0076] The mounting cavity 4 extends through the rear wall 24 along its length. That is, the length of the mounting cavity 4 is the same as the length of the rear wall 24.

[0077] The mounting cavity 4 is a recessed cavity formed within the rear wall 24 of the door body 2. The length direction of the mounting cavity 4 is the same as that of the rear wall 24, and the starting and ending ends of the mounting cavity 4 are aligned with the two opposite end faces of the rear wall 24 along its length, ensuring that the mounting cavity 4 covers the entire length of the rear wall 24. For example, if the length of the rear wall 24 of the door body 2 is 2 meters, then the length of the mounting cavity 4 is the same as the length of the rear wall 24 of the door body 2, which is also 2 meters.

[0078] In one embodiment, the rear side of the freezer 100 includes two hinges 3 spaced apart. The two hinges 3 are arranged in the same manner in the mounting cavity 4 and connect the door 2 to the back panel 11 of the cabinet 1.

[0079] The length of the mounting cavity 4 is the same as the length of the rear wall 24, so that the hinge 3 does not need to be precisely aligned in the length direction of the rear wall 24 when it is installed in the door body 2, which effectively improves the installation efficiency of the freezer. In addition, since the length of the mounting cavity 4 is the same as the length of the rear wall 24, when installing the hinge 3, there is no need to make a pre-embedded box. It is only necessary to bend at the corresponding position of the rear wall 24 of the door body 2, which effectively reduces the manufacturing cost.

[0080] The second hinge seat 32 includes a second connecting part 321, which is connected to the door body 2 and located in the mounting cavity 4. Specifically, the second connecting part 321 is connected to the second surface of the mounting cavity 4.

[0081] The second connecting part 321 is a plate-like or block-like structure extending upward from the pivoting part 33 of the hinge 3. This ensures that the second connecting part 321 is parallel to the vertical recessed wall 22 of the mounting cavity 4, achieving a zero-angle fit between the second connecting part 321 and the recessed wall 22 of the mounting cavity 4. This prevents the second connecting part 321 from being installed at an angle, which could cause interference when the door 2 is opened or closed. The width of the second connecting part 321 in the vertical direction is less than the height of the recessed wall 22 in the vertical direction, ensuring that the second connecting part 321 and part of the pivoting part 33 can be inserted into the mounting cavity 4 without interference.

[0082] By placing the second connecting part 321 in the mounting cavity 4, it can be effectively ensured that the pivoting part 33 of the hinge 3 will not collide with the top or bottom of the mounting cavity 4 when it rotates, thus ensuring the smooth opening and closing of the door 2.

[0083] The second connecting part 321 is fixed to the door body 2 by bolts or clips. Specifically, the second connecting part 321 is fixed to the second surface of the mounting cavity 4 by fasteners.

[0084] The first hinge seat 31 includes a first connecting part 311, which protrudes from the mounting cavity 4 and extends downward to connect to the first surface of the rear back plate 11 of the housing 1.

[0085] The first connecting part 311 is a plate-shaped or block-shaped structure that protrudes downward from the pivot part 33 of the hinge 3. The first connecting part 311 protrudes from the mounting cavity 4, that is, the first connecting part 311 is connected to the pivot part 33 at the first connecting position, which is located outside the mounting cavity 4.

[0086] From the first connection position, the first connection part 311 protrudes downward in the vertical direction and connects to the rear back panel 11 of the box body 1. Specifically, the first connection part 311 is close to the inner surface of the box body 1 and tightly fits the outer surface of the rear back panel 11 of the box body 1.

[0087] The first connecting part 311 protrudes from the mounting cavity 4 and extends downward to connect to the rear panel 11 of the housing 1. Specifically, the first connecting part 311 of the first hinge seat 31 is connected to the first surface of the housing 1. The connection of the first connecting part 311 to the housing 1 effectively disperses the impact force generated by the door 2 during opening and closing to the rear panel 11 of the housing 1 through the first connecting part 311, making the connection between the hinge 3 and the rear panel 11 of the housing 1 more stable.

[0088] The first hinge seat 31 includes a first hinge portion 312 tangentially connected to the first connecting portion 311, and the second hinge seat 32 includes a second hinge portion 322 pivotally connected to the first hinge portion 312 to form the pivot portion 33. The second hinge portion 322 has a vertical planar structure 326, which is flush with the outer side wall of the first connecting portion 311.

[0089] In one embodiment, both the first hinge portion 312 and the second hinge portion 322 are cylindrical structures, and the first hinge portion 312 and the second hinge portion 322 are connected end to end and coaxially arranged. A connecting shaft 331 is provided inside to pass through the first hinge portion 312 and the second hinge portion 322. The first hinge portion 312, the second hinge portion 322 and the connecting shaft 331 together form the pivot portion 33 of the hinge 3.

[0090] In this application, the first hinge portion 312 and the second hinge portion 322 are horizontally positioned in the mounting cavity 4 with the connecting shaft 331 horizontally positioned.

[0091] The first hinge part 312 is fixedly connected to the back panel 11 of the box body 1 through the first connecting part 311, and the second hinge part 322 is fixedly connected to the rear side of the door body 2 through the second connecting part 321. The second hinge part 322 serves as the rotating end of the pivot part 33 and is connected to the first hinge part 312 through the connecting shaft 331, so that the door body 2 can be fixed to the opening of the box body 1 when it is opened and closed.

[0092] The first connecting part 311 is tangentially connected to the first hinge part 312 of the pivot part 33. Specifically, the first hinge part 312 has a cylindrical structure and has the farthest point from the inner wall 22 as the first connection position. The first connecting part 311 is connected to the first hinge part 312 at the farthest point and protrudes downward along the tangent extension direction of the farthest point, so that the first hinge seat 31 is in a vertical plane on the outer wall away from the inner wall 22.

[0093] This ensures that the outer wall of the first hinge portion 312 and the first connecting portion 311 forms a continuous support, and ensures that the connection between the first connecting portion 311 and the first hinge portion 312 is seamless at the first connection position, thereby reducing stress concentration.

[0094] The second hinge portion 322 has a vertical planar structure 326. Specifically, an arc-shaped structure is cut off in the vertically downward direction at a position away from the recessed wall 22 in the second hinge portion 322. After the arc-shaped structure is cut off, a vertical planar structure 326 is formed at a position away from the front wall 21 in the second hinge portion 322. The planar structure 326 is flush with the outer wall of the first hinge seat 31.

[0095] The planar structure 326 of the second hinge part 322 is flush with the outer side wall of the first connecting part 311, which can effectively reduce the amount of hinge 3 protrusion, improve the appearance of the container 1, and increase the loading capacity during transportation, thereby reducing production costs.

[0096] The second connecting part 321 is provided with at least one first fixing hole 324, the first fixing hole 324 is an elongated hole, and the length direction of the first fixing hole 324 is vertical.

[0097] The second connecting part 321 is connected to the rear side of the door body 2 through the first fixing hole 324 via a fastener. Specifically, the second connecting part 321 is connected to the rear wall 24 of the door body 2 through the first fixing hole 324 via a fastener; specifically, the second connecting part 321 is connected to the recessed wall 22. The first fixing hole 324 is an elongated hole, therefore, the cross-section of the first fixing hole 324 is rectangular or elliptical, and the length direction of the first fixing hole 324 is vertical.

[0098] The elongated hole allows the door 2 to be finely adjusted in the vertical direction to make the distance between it and the box 1 finely adjusted. This means that when assembling the door 2 and the box 1, there is no need for precise alignment. You can simply insert the fastener into the first fixing hole 324, adjust the position of the door 2 in the vertical direction, and then lock it.

[0099] Fasteners can be bolts, rivets, etc.

[0100] The second connecting part 321 effectively improves the assembly efficiency between the door body 2 and the box body 1 by setting a vertically elongated first fixing hole 324.

[0101] The second connecting portion 321 includes a first reinforcing rib 323 surrounding its edge, and the first reinforcing rib 323 is provided with an arc-shaped placement portion 325 in the length extension direction of the first fixing hole 324.

[0102] The first reinforcing rib 323 is a continuous or segmented rib structure surrounding the edge of the second connecting part 321, forming a closed ring or near-ring-shaped reinforcing structure.

[0103] The first reinforcing rib 323 is provided with an arc-shaped placement portion 325 in the length extension direction of the first fixing hole 324, that is, the center line of the arc-shaped placement portion 325 coincides with the center line of the elongated hole.

[0104] When the second connecting part 321 is fixedly connected to the rear side of the door body 2 by screws, the curvature of the arc-shaped placement part 325 matches the outer contour of the screw head of the screw inserted into the first fixing hole 324.

[0105] The arc-shaped placement part 325 can be a semi-circular or U-shaped groove.

[0106] The screw's movement path within the first fixing hole 324 completely covers the length of the first fixing hole 324. When the screw moves to the uppermost or lowermost end within the first fixing hole 324, the screw head may interfere with the first reinforcing rib 323 due to positional displacement. By providing an arc-shaped positioning portion 325 on the first reinforcing rib 323 along the length extension direction of the first fixing hole 324, the screw can achieve local avoidance at the extreme positions of the first fixing hole 324, thereby eliminating the interference of the first reinforcing rib 323 on the screw.

[0107] In one embodiment, the freezer 100 disclosed in this application further includes a first reinforcing member, which is plate-shaped or sheet-shaped. The first reinforcing member is disposed on the side of the rear wall 24 of the door body 2 away from the hinge 3 and is tightly fitted to the surface of the rear wall 24 of the door body 2 away from the hinge 3. The second hinge seat 32 is connected to the first reinforcing member through the rear wall 24 of the door body 2 by fasteners such as bolts or rivets.

[0108] The first reinforcing member disperses the impact force of the hinge 3 during the flipping process of the door 2, so that a stable connection is formed between the hinge 3 and the door 2.

[0109] In another embodiment, the freezer 100 disclosed in this application further includes a second reinforcing member, which is plate-shaped or sheet-shaped. The second reinforcing member is disposed on the side wall of the rear back panel 11 of the cabinet 1 near the interior of the cabinet 1 and is tightly fitted to the side wall of the rear back panel 11 near the interior of the cabinet 1. The first hinge seat 31 is connected to the second reinforcing member through the rear back panel 11 of the cabinet 1 by fasteners such as bolts or rivets.

[0110] The second reinforcing member disperses the impact force of the hinge 3 during the flipping process of the door 2, so that the hinge 3 and the box 1 are stably connected.

[0111] In the third embodiment, the door body 2 includes a front wall 21 disposed opposite to the rear wall 24. The rear wall 24 includes a protruding edge 23 at its lower end and protruding away from the front wall 21, and an indented wall 22 at its upper end and recessed towards the front wall 21. The upper surface of the protruding edge 23 is connected to the indented wall 22 and surrounds the mounting cavity 4. The indented wall 22 is the second surface connected to the second hinge seat 32.

[0112] The lower end of the rear wall 24 is provided with a protruding edge 23 extending away from the front wall 21. The protruding edge 23 increases the lateral dimension of the lower end of the rear wall 24, forming a boundary extending away from the front wall 21. At the same time, the upper end of the rear wall 24 includes an indented wall 22 recessed towards the front wall 21. The protruding edge 23 is located at the lower end of the rear wall 24, and its outward protrusion direction is spatially misaligned with the front wall 21, so that the cross section of the rear wall 24 presents a stepped shape.

[0113] Furthermore, the upper surface of the protruding edge 23 is seamlessly connected to the lowermost end of the recessed wall 22, forming a semi-enclosed mounting cavity 4. In the third embodiment, the mounting cavity 4 extends upward through the uppermost part of the rear wall 24, that is, the mounting cavity 4 penetrates the upper surface of the door body 2.

[0114] The upper surface of the protruding edge 23 is connected to the recessed wall 22 and forms an installation cavity 4. That is, the installation cavity 4 is located at the upper end of the rear wall 24 and penetrates the upper surface of the door body 2. Specifically, the pivot part 33 is located in the installation cavity 4, and the first hinge seat 32 is fixedly connected to the recessed wall 22.

[0115] The hinge 3 and other components can be installed and removed through the semi-enclosed mounting cavity 4 at the upper end of the rear wall 24 without disassembling the entire rear wall 24, which improves the convenience of maintenance of the hinge 3 and other components. At the same time, the protruding edge 23 is set at the lower end of the rear wall 24, which effectively compensates for the structural strength of the lower end of the rear wall 24 of the door body 2, so that the door body 2 can maintain its resistance to deformation while reducing its weight.

[0116] This application also provides a third embodiment, in which the recessed wall 22, the upper surface 233 of the protruding edge, and the outer surface 232 of the protruding edge are all planar. In this case, the recessed wall 22 is parallel to and does not coincide with the first surface. Of course, the recessed wall 22, the upper surface 233 of the protruding edge, and the outer surface 232 of the protruding edge can also be set as other curved surfaces adapted to the hinge 3. In this case, the extension surface of the recessed wall 22 and the extension surface of the first surface partially intersect. This application does not impose specific limitations.

[0117] In the third embodiment, the mounting cavity 4 penetrates the rear wall 24 along its length. That is, the length of the mounting cavity 4 is the same as the length of the rear wall 24. For details, please refer to the above-described arrangement where the mounting cavity 4 penetrates the rear wall 24 along its length; further details will not be repeated here.

[0118] This application also provides a fourth embodiment, wherein the mounting cavity 4 extends through both the thickness direction and the length direction of the rear wall 24. Alternatively, the rear wall 24 of the door body 2 is translated relative to the extension surface of the back panel 11 of the box body 1 in a direction closer to the front wall 21, and the rear wall 24 as a whole serves as the second surface for mounting the second hinge seat 32.

[0119] In the fourth embodiment, the highest end of the mounting cavity 4 is the same as the highest end of the rear wall 24, the lowest end of the mounting cavity 4 is the same as the lowest end of the rear wall 24, and the starting end and ending end of the mounting cavity 4 are aligned with the two end faces opposite to the length direction of the rear wall 24, respectively.

[0120] The overall translation of the rear wall 24 makes its cross-section with the back panel 11 of the box 1 step-shaped or staggered. A certain distance is formed between the plane of the rear wall 24 and the back panel 11 of the box 1, so that the mounting cavity 4 passes through the thickness and length directions of the rear wall 24 at the same time, forming a channel-like mounting space in the rear of the door 2 that is unobstructed in the upper, lower and left and right directions.

[0121] In the fourth embodiment, the rear wall 24 is in a vertical plane state, such that the second surface for mounting the second hinge seat 32 is parallel to the first surface and does not intersect; of course, the rear wall 24 may also be configured as other curved surfaces adapted to the hinge 3, such that the extension surface of the second surface for mounting the second hinge seat 32 partially intersects the extension surface of the first surface.

[0122] The mounting cavity 4 extends through both the thickness and length of the rear wall 24, facilitating future maintenance. The hinge 3 can be installed and removed from the rear side of the door 2 without disassembling the rear wall 24 or the door 2, reducing maintenance difficulty and cost.

[0123] In the fifth embodiment, the upper edge of the mounting cavity 4 is lower than the highest point of the rear wall 24, and the lower edge of the mounting cavity 4 is higher than the lowest point of the rear wall 24.

[0124] Alternatively, in the fifth embodiment, along the height direction of the rear wall 24, the central region of the rear wall 24 is recessed inward toward the front wall 21, forming a recessed mounting cavity 4. The upper edge of the mounting cavity 4 is lower than the highest point of the rear wall 24, and the lower edge of the mounting cavity 4 is higher than the lowest point of the rear wall 24. The mounting cavity 4 is confined to the central region of the rear wall 24, and its cross-section is groove-shaped. That is, the top and bottom of the rear wall 24 retain a complete planar shape, while the central part is recessed to form the mounting cavity 4.

[0125] This application also provides a fifth embodiment, wherein the cross-section of the mounting cavity 4 is an arc-shaped surface, and the arc-shaped surface serves as the second surface for mounting the second hinge seat 32. Specifically, the arc-shaped surface of the mounting cavity 4 is an arc-shaped surface that is concave toward the front end of the freezer.

[0126] In the fifth embodiment, the mounting cavity 4 penetrates the rear wall 24 along its length. That is, the length of the mounting cavity 4 is the same as the length of the rear wall 24. For details, please refer to the above-described arrangement where the mounting cavity 4 penetrates the rear wall 24 along its length; further details will not be repeated here.

[0127] Of course, in the fifth embodiment, the length of the mounting cavity 4 along the length direction of the rear wall 24 can also be set to be less than the length of the rear wall 24.

[0128] In the fifth embodiment, the top and bottom of the rear wall 24 retain a planar shape, which can effectively withstand the impact force when the door 2 is opened or closed; the concave area in the middle of the rear wall 24 disperses stress through an arc and adapts to the pivot part of the hinge 3, avoiding local deformation and improving the overall deformation resistance.

[0129] In the fifth embodiment, the extension surface of the arcuate surface of the mounting cavity 4 for mounting the second hinge seat 32 intersects with the extension surface of the first surface in a partial manner.

[0130] This application also provides a sixth embodiment, wherein the height of the mounting cavity 4 in the vertical direction is the same as the thickness of the door body 2, and the dimension of the mounting cavity 4 in the length direction of the rear wall 24 is smaller than the length of the rear wall 24.

[0131] The mounting cavity 4 is located on the rear wall 24 of the door body 2. The dimension of the mounting cavity 4 along the length of the rear wall 24 is smaller than the total length of the rear wall 24. In other words, the mounting cavity 4 does not cover the entire length of the rear wall 24 along the length of the rear wall 24, but rather a reserved edge area is provided in the rear wall 24 for the mounting cavity 4.

[0132] Specifically, the mounting cavity 4 is recessed relative to the back panel 11 of the cabinet 1. A second surface is formed in the mounting cavity 4 near the front end of the freezer, which serves as the exclusive mounting surface for the second hinge seat 32. Its extension surface is parallel to and does not overlap with the extension surface of the first surface.

[0133] The depth of the second surface recess relative to the first surface is set according to actual needs, and this application does not impose specific limitations.

[0134] In the sixth embodiment, the dimension of the mounting cavity 4 along the length of the rear wall 24 is smaller than the length of the rear wall 24, which ensures that part of the pivot portion of the hinge 3 can be accommodated in the mounting cavity 4, and improves the sealing between the door 2 and the box 1 when closed by the reserved edge area.

[0135] This application also provides a seventh embodiment in which the second hinge seat 32 passes through the lower surface of the door body 2 and connects to the side of the rear wall 24 facing the front end of the freezer.

[0136] Specifically, the lower surface of the door 2 has a through hole for the second hinge seat 32 to pass through. The size of the through hole matches the cross-sectional shape of the second hinge seat 32, ensuring that the second hinge seat 32 can pass through smoothly. The second hinge seat 32 passing through the through hole is fixed to the mounting surface of the rear wall 24 facing the front end of the freezer.

[0137] At this time, the side of the rear wall 24 facing the front end of the freezer is the second surface on which the second hinge seat 32 is installed. At this time, the second surface is parallel to the first surface on which the first hinge seat 31 is installed and they do not overlap.

[0138] Of course, a channel cavity 25 that is recessed toward the front end of the refrigerator 100 can also be provided at the lower end of the rear wall 24 of the door body 2. Specifically, the channel cavity 25 is semi-open or U-shaped, the opening of the channel cavity 25 faces away from the front wall 21 of the door body 2, and the bottom is open, serving as a channel through which the second hinge seat 32 passes.

[0139] The cross-sectional shape of the channel cavity 25 can be set to a right angle, an arc or other shapes according to actual needs.

[0140] The second hinge seat 32 passes through the through hole on the lower surface of the door body 2 from the opening area of ​​the channel cavity 25 at the bottom of the door body 2, and contacts the mounting surface of the rear wall 24 facing the front end of the freezer, and is fixed by means of screw fastening, snap-on positioning or welding.

[0141] In the seventh embodiment, the second hinge seat 32 passes through the lower surface of the door body 2 and connects to the side of the rear wall 24 facing the front end of the freezer, reducing the size of the hinge protruding from the outside of the cabinet, increasing the actual load / cabinet load during assembly and transportation, and effectively reducing the actual production cost.

[0142] This application also provides an eighth embodiment, which is similar to the first and / or second embodiments. However, in the eighth embodiment, along the length direction of the rear wall 24 of the door body 2, the protruding edge 23 has the same length as the mounting cavity 4 and is shorter than the length of the rear wall 24 of the door body 2. The installation method of the hinge 3 and the length of the protruding edge 23 protruding from the recessed wall 22 are the same as in the first embodiment, and will not be described again here.

[0143] This application relates to a freezer 100, including a cabinet 1, a door 2, and at least one hinge 3. The door 2 is openable and closeable at the opening via the hinge 3. The hinge 3 includes a first hinge seat 31 and a second hinge seat 32, which are rotatably connected via a pivot 33. The first hinge seat 31 is connected to the first surface of the rear panel 11 of the cabinet 1, and the second hinge seat 32 is connected to the second surface of the rear wall 24 of the door 2. By making the first surface connecting the first hinge seat 31 and the second surface connecting the second hinge seat 32 non-convex surfaces, this application reduces the size of the hinge 3 protruding from the cabinet 1, increases the actual assembly capacity during assembly and transportation, and effectively reduces actual production costs.
