[0033] 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.

[0034] To address the aforementioned issues, this application provides a freezer 100, wherein the opening side of the door 2 of the freezer 100 is the front, that is, the standing side of the user when operating the freezer 100 is the front of the freezer 100, the rear wall of the cabinet 1 opposite to the front of the door 2 is the rear, and the back panel 7 of the freezer 100 is located on the rear side of the cabinet 1.

[0035] This application provides a freezer 100, including a cabinet body 1 with a cabinet opening 4, a frame 6 disposed around the cabinet opening 4, and a door 2 covering the cabinet opening 4. The door 2 and the cabinet body 1 are pivotally connected by a hinge assembly 3. The hinge assembly 3 includes an upper hinge 32 and a lower hinge 31 pivotally connected to each other. The upper hinge 32 is connected to the door 2, and the lower hinge 31 is connected to the cabinet body 1. The cabinet body 1 includes a back panel 7 disposed on the rear side. The frame 6 includes a rear frame located on the rear side. The rear frame is provided with a mounting portion 9 that is partially recessed forward relative to the back panel 7. The mounting portion 9 and the back panel 7 form a mounting cavity. At least a portion of the lower hinge 31 is located within the mounting cavity.

[0036] The top of the cabinet 1 forms a cabinet opening 4 for storing and retrieving items; the door 2 can pivotally close to the cabinet opening 4 via a hinge assembly 3, and the size of the door 2 is adapted to fit the size of the cabinet opening 4 to maintain a low-temperature environment inside the freezer 100.

[0037] The hinge assembly 3 is divided into two parts: an upper hinge 32 and a lower hinge 31. The upper hinge 32 is fixed to the side of the door 2 and rotates synchronously with the door 2. The lower hinge 31 includes a fixing part 310, which is directly connected to the cabinet 1. The upper hinge 32 and the lower hinge 31 are connected by a pin or bearing to ensure that the door 2 opens or closes smoothly on the cabinet 1.

[0038] A frame 6 is provided around the perimeter of the cabinet opening 4. The frame 6 is fixed to the upper end of the cabinet body 1 by means of buckles or other connections. The frame 6 extends horizontally along the perimeter of the cabinet opening 4 to form a contact surface that contacts the bottom surface of the door body 2.

[0039] The frame 6 includes a rear frame disposed on the rear side of the freezer 100. The rear frame is configured with a mounting part 9 that is recessed inward relative to the back panel 7 at the position corresponding to the fixing part 310 of the lower hinge 31. That is, the mounting part 9 is recessed inward toward the interior of the cabinet 1. The back panel 7 is disposed in the direction away from the interior of the cabinet 1 from the mounting part 9. The inner surface of the back panel 7 is disposed opposite to the mounting part 9 and together with the mounting part 9, they enclose a mounting cavity for accommodating the fixing part 310 of the lower hinge 31.

[0040] Specifically, the mounting cavity is configured to include four side walls in the vertical direction, three of which are formed by recesses of the frame 6 partially facing the interior of the cabinet, and one side wall away from the interior of the cabinet 1 is formed by the back panel 7.

[0041] In one embodiment, the mounting cavity opening faces upward.

[0042] When assembling the lower hinge 31, the fixing part 310 of the lower hinge 31 is inserted into the mounting cavity from the opening of the mounting cavity downwards, and the back plate 7, the fixing part 310 of the lower hinge 31 and the frame 6 are connected simultaneously by the fastener 8.

[0043] By providing a recessed mounting portion 9 in the rear frame that forms a mounting cavity for the lower hinge 31 together with the back panel 7, at least a portion of the lower hinge 31 is hidden within the mounting cavity. This effectively reduces the risk of damage to the lower hinge 31 and makes the freezer 100 more aesthetically pleasing. In addition, the outer side of the fixing portion 310 of the lower hinge 31 is attached to the inner surface of the back panel 7. When the force of opening or closing the door 2 is applied to the lower hinge 31, the back panel 7 has a large support surface, which can disperse the force on the lower hinge 31 and enhance the load-bearing capacity of the lower hinge 31.

[0044] The mounting cavity includes an upper chamber 92 and a lower chamber 93 that are connected vertically, and the back plate 7 forms the rear wall of the upper chamber 92.

[0045] Specifically, the upper chamber 92 and the lower chamber 93 are vertically connected to each other. The upper chamber 92 has a rearward opening, which is covered by the back panel 7 of the cabinet 1, forming the rear wall of the upper chamber 92; the lower chamber 93 is formed entirely by stamping the frame 6.

[0046] In other words, the back plate 7 fits tightly against the rear of the mouth frame 6, sealing the rear opening of the upper chamber 92, and together with the mounting part 9 of the mouth frame 6, forms a semi-closed upper chamber 92; while at the position of the lower chamber 93, the back plate 7 does not constitute any wall of the lower chamber 93.

[0047] The back plate 7, serving as the rear wall of the upper chamber 92, is directly connected to the fixing part 310 of the lower hinge 31. This effectively disperses the force exerted on the lower hinge 31 when the door 2 is opened or closed, greatly improving the load-bearing capacity of the lower hinge 31. The lower chamber 93 ensures that the lower hinge 31 is stably installed in the mounting cavity. Even when the back plate 7 is removed, the lower part of the lower hinge 31 remains stable in the vertical direction because it is confined within the lower chamber 93.

[0048] The lower hinge 31 is engaged and fixed to the back plate 7.

[0049] Specifically, the outer side of the fixing part 310 of the lower hinge 31 may be provided with hooks, protrusions and other structures facing the back plate 7, and the back plate 7 is provided with corresponding holes, slots and other structures.

[0050] The lower hinge 31 is fixed to the back panel 7, which restricts the degree of freedom of movement of the lower hinge 31 in the front-back and / or left-right directions of the freezer 100. This not only enables the lower hinge 31 to be pre-positioned quickly during installation, but also effectively enhances the stability of the lower hinge 31 installation.

[0051] The fixing part 310 of the lower hinge 31 is at least partially located in the mounting cavity. The fixing part 310 includes a fixing part body and a locking protrusion structure 316 extending rearward from the fixing part body. The back plate 7 is provided with a locking groove 73 that cooperates with the locking protrusion structure 316. The locking protrusion structure 316 is engaged in the locking groove 73.

[0052] The back plate 7 is provided with a slot 73, which is configured to form a complementary groove structure with the protruding structure 316 of the fixing part 310 of the lower hinge 31. The opening size, peripheral contour and depth of the slot 73 are adapted to the protruding structure 316.

[0053] Specifically, the slot 73 is configured as a U-shaped groove extending downward from the upper edge of the back plate 7, forming a channel from top to bottom. That is, the opening of the slot 73 faces upward and connects to the upper edge of the back plate 7. When the lower hinge 31 is inserted into the mounting cavity from top to bottom, the protruding structure 316 slides vertically downward from the upper opening of the slot 73 into the slot 73 and is limited and fixed by the slot 73.

[0054] By setting the locking protrusion 316 and the locking groove 73 to cooperate with each other, the locking protrusion 316 of the lower hinge 31 is aligned with the locking groove 73 on the back plate 7, which can quickly pre-position the lower hinge 31 during installation, effectively simplifying the pre-positioning method of the lower hinge 31 during installation.

[0055] In one embodiment, the outline dimension of the card protrusion structure 316 is smaller than the periphery dimension of the card slot 73.

[0056] Specifically, after the protruding structure 316 extends rearward from the main body of the fixing part, when the protruding structure 316 is confined within the slot 73, there is a certain gap between the two at the periphery, so that when the protruding structure 316 enters the slot 73, the gap between the two can be used for correction, simplifying the installation operation. At the same time, when the protruding structure 316 is confined within the slot 73, it protrudes towards the rear side of the back plate 7, which can cover at least part of the back plate 7 to a certain extent.

[0057] The slot 73 is located in the upper chamber 92, that is, the depth of the slot 73 from top to bottom is less than or equal to the depth of the upper chamber 92.

[0058] The upper chamber 92 is a space formed by the mounting part 9, which is formed by the forward inward recess of the rear frame of the mouth frame 6, and the back plate 7. The slot 73 is set on the back plate 7 and is completely located within the depth range of the upper chamber 92. There is no need to make a complex structural design for the latching protrusion structure 316 of the lower hinge 31, which effectively simplifies the latching and fixing method between the lower hinge 31 and the back plate 7.

[0059] The fixing part 310 includes a first fixing part 311 and a second fixing part 314 connected vertically. The first fixing part 311 is located in the upper chamber 92, and the second fixing part 314 is located in the lower chamber 93.

[0060] The first fixing part 311 and the second fixing part 314 are connected in the vertical direction to form a whole.

[0061] The first fixing part 311 is engaged with the slot 73 of the back plate 7 located in the upper chamber 92 through its locking protrusion structure 316, so as to disperse the force generated on the lower hinge 31 when the door 2 is opened or closed by the back plate 7. The second fixing part 314 is limited to the lower chamber 93. After the back plate 7 is removed, the lower chamber 93 can provide the lower hinge 31 with the support force from the rear of the fixing part 310 of the lower hinge 31, so as to prevent the lower hinge 31 from tilting backward.

[0062] The mounting part 9 includes a bottom wall, which is arranged horizontally. The lower chamber 93 includes a second rear wall extending upward on the side of the bottom wall near the back plate 7. The thickness of the first fixing part 311 is greater than the thickness of the second fixing part 314. A step is formed at the connection between the first fixing part 311 and the second fixing part 314. The lower surface of the step abuts against the upper edge of the second rear wall.

[0063] Specifically, the second rear wall is approximately parallel to the back plate 7, and the second rear wall, together with the bottom wall and the side wall of the mounting part 9 of the mouth frame 6, forms a lower chamber 93 that is open at the top and communicates with the upper chamber 92.

[0064] The first fixing part 311 of the lower hinge 31 located in the upper chamber 92 is configured to have a larger thickness, while the second fixing part 314 located in the lower chamber 93 is configured to have a smaller thickness, and a step is formed at the connection between the first fixing part 311 and the second fixing part 314.

[0065] The stepped portion has a downward-facing lower surface, and the second rear wall extends upward. When the lower surface of the stepped portion abuts against the upper edge of the second rear wall, the upper edge of the second rear wall positions the lower hinge 31 in the vertical direction while providing upward support to the lower hinge 31. This effectively prevents the lower hinge 31 from shifting downward due to long-term use, thereby enhancing the service life of the entire freezer 100.

[0066] The mounting part 9 includes a first sidewall, a second sidewall, and a third sidewall connecting the first sidewall and the second sidewall. The first sidewall and the second sidewall are provided with vertically extending protrusions. The protrusions and the third sidewall form two opposing first grooves 94. The two sides of the fixing part 310 arranged along the width direction are located in the first grooves 94.

[0067] The mounting section 9 is formed by the first side wall, the second side wall, and the third side wall connecting the two.

[0068] Vertically extending protrusions are provided on the inner surfaces of the first and second sidewalls. Two parallel first grooves 94 with opposite openings are formed between the protrusions and the third sidewall.

[0069] The first groove 94 extends vertically.

[0070] The distance between the two sides of the fixing part 310 in the width direction of the lower hinge 31 is adapted to the distance between the two opposing first slide grooves 94, so that the two sides of the fixing part 310 in the width direction can be simultaneously embedded in the left and right first slide grooves 94.

[0071] The first, second, and third sidewalls of the protrusion and the mounting part 9 restrict the movement freedom of the fixing part 310 in both the front-back and left-right directions by the first slide groove 94, thereby improving the stability of the lower hinge 31 installed in the mounting cavity.

[0072] The frame 6 includes a fixing groove 91 formed by horizontally protruding backward from its upper edge and then bending downward, and the upper edge of the back plate 7 is located in the fixing groove 91.

[0073] The rear back panel 7 and the frame 6 of the freezer 100 are recessed to form the mounting cavity for the lower hinge 31, which hides the fixing part 310 of the lower hinge 31. This effectively reduces the size of the hinge exposed on the outside of the back panel 7. At the same time, the back panel 7 can distribute the force transmitted by the door 2 through the lower hinge 31 in all directions, effectively improving the deformation resistance of the cabinet 1 at the mounting position of the lower hinge 31.

[0074] The mouth frame 6 includes a fixing groove 91 formed by horizontally protruding backward from its upper edge and then bending downward. Specifically, the mouth frame 6 includes a main body part of the mouth frame 6 connected to the mounting part 9. The main body part of the mouth frame 6 includes a fixing groove 91 formed by horizontally protruding backward from its upper edge and then bending downward. The upper edge of the back plate 7 is limited to the fixing groove 91.

[0075] The main body of the frame 6 is configured to be connected to the mounting part 9. The fixing groove 91 is configured to extend horizontally backward from the upper edge of the main body of the frame 6 and then bend downward to avoid the opening of the mounting part 9 for the insertion of the lower hinge 31.

[0076] The upper edge of the back plate 7 is located in the fixing groove 91. The fixing groove 91 fixes the back plate 7 from the upper edge of the back plate 7 and the upper rear side of the back plate 7. Specifically, the part of the fixing groove 91 that protrudes backward from the upper edge of the main body of the frame 6 covers the upper edge of the back plate 7, and the part that bends downward is located on the outside of the upper edge of the back plate 7.

[0077] The continuous contact between the fixing groove 91 and the back panel 7 can effectively fix the back panel 7 and the frame 6, enhancing the overall structural strength of the freezer 100.

[0078] The rear frame also includes at least one first limiting groove 62 recessed in a direction away from the back plate 7. The back plate 7 includes a back plate body and a first limiting part 71. The first limiting part 71 bends forward from the side of the back plate 7 that is vertically arranged. The top of the first limiting part 71 is located in the first limiting groove 62.

[0079] At least one first limiting groove 62 is formed on the rear frame through processes such as stamping, which is recessed in a direction away from the back panel 7. In other words, the first limiting groove 62 is recessed in a direction toward the interior of the cabinet 1 of the freezer 100.

[0080] The vertically arranged side of the back plate 7 is processed to bend forward to form a first limiting part 71 on the vertically arranged side of the back plate 7. The bending direction and the size of the first limiting part 71 after bending are adapted to the first limiting groove 62.

[0081] When the freezer 100 is assembled, the top of the first limiting part 71 of the back panel 7 is embedded into the first limiting groove 62 of the rear frame. This effectively prevents relative displacement between the back panel 7 and the frame 6, enhancing the rigidity and integrity of the entire cabinet 1 structure.

[0082] The first limiting groove 62 includes a first groove wall, a second groove wall and a guide rib 621 vertically disposed on the first groove wall and / or the second groove wall; and the first groove wall and the second groove wall are respectively located on both sides of the first limiting part 71.

[0083] The bottom end of the guide rib 621 gradually converges from bottom to top, that is, it is set to form a gradually converging wedge shape from the bottom end of the first limiting groove 62 upward. In other words, in the direction from bottom to top, the starting part of the guide rib 621 is relatively thin, forming a smooth guide slope. As the height increases, the thickness of the guide rib 621 protruding from the first groove wall and / or the second groove wall gradually increases.

[0084] The guide rib 621's guide ramp allows the first limit to be accurately set within the first limit groove 62, effectively improving the assembly speed of the back plate 7 and the frame 6.

[0085] The rear frame also includes at least one second limiting groove 64 recessed into the cabinet 1. The back panel 7 includes a back panel body and a second limiting part 72 extending laterally from the upper edge of the back panel body away from the back panel 7. The width of the second limiting part 72 is adapted to the width of the second limiting groove 64, and the top of the second limiting part 72 is located in the second limiting groove 64.

[0086] Specifically, the frame 6 includes an upper frame 63, which extends along the periphery of the cabinet opening 4. At least one second limiting groove 64 recessed into the cabinet body 1 is formed on the rear frame of the cabinet opening 4 by processes such as stamping. The lower surface of the upper frame 63 serves as the top wall of the second limiting groove 64.

[0087] The back panel 7 has a second limiting part 72 that extends laterally away from the back panel 7 at its upper edge, or in other words, the second limiting part 72 extends toward the interior of the cabinet 1.

[0088] In one embodiment, the upper edge of the back plate 7 is provided with a plurality of spaced second limiting portions 72, and the widths of the plurality of second limiting portions 72 in the left and right directions may be the same or different.

[0089] During assembly, the mouth frame 6 is installed from top to bottom, and the second limiting groove 64 slides down along the second limiting part 72 of the back plate 7 until the lower surface of the upper frame 63 abuts against the upper surface of the second limiting part 72.

[0090] In one embodiment, the width of the second limiting part 72 is adapted to the width of the second limiting groove 64. That is, the width of the second limiting part 72 and the second limiting groove 64 are set to fit tightly in the left and right directions of the freezer 100, with almost no room for movement, so that the back panel 7 and the frame 6 have no relative displacement in the left and right directions.

[0091] The freezer 100 also includes fasteners 8; the fasteners 8 are connected sequentially from back to front to the back panel 7, the lower hinge 31 and the mounting part 9.

[0092] The back plate 7 is located at the rearmost position. The front wall of the back plate 7 is in close contact with the fixing part 310 of the lower hinge 31, while the frontmost part is the mounting part 9 of the frame 6. The fastener 8 is inserted from the rear to the front and passes through the back plate 7, the lower hinge 31 and the mounting part 9 in sequence.

[0093] The back plate 7, lower hinge 31 and mounting part 9 are connected in sequence by fasteners 8, so that when the force generated by the opening or closing of the door 2 is applied to the lower hinge 31, it will be transmitted to the frame 6 and the back plate 7 at the same time, so as to distribute the load of the lower hinge 31 and improve the load bearing capacity of the lower hinge 31 during the pivoting process of the door 2.

[0094] In one embodiment, the fastener 8 is configured as a screw, bolt, or rivet, etc.

[0095] In an optional embodiment, the lower hinge 31 fixing part 310 is provided with a fixing hole 315 for the fastener 8 to pass through. The fixing hole 315 is formed in the thicker first fixing part 311. The thicker first fixing part 311 increases the engagement length between the fixing hole 315 and the fastener 8, effectively improving the connection force of the fastener 8 on the back plate 7, the lower hinge 31 and the mounting part 9.

[0096] The freezer 100 also includes a reinforcing member 5 disposed on the side of the mounting part 9 away from the back panel 7; the fastener 8 connects the back panel 7, the lower hinge 31, the mounting part 9 and the reinforcing member 5 in sequence from back to front.

[0097] The reinforcing member 5 and the fixing part 310 of the lower hinge 31 are located on opposite sides of the frame 6. That is, on the rear side of the freezer 100, from the outside of the freezer 100 to the inside of the freezer 100, the fixing part 310 of the lower hinge 31 is on the outside, and the fixing part 310 is close to the outer surface of the frame 6. Next is the frame 6, and then the reinforcing member 5 is on the inside, and the reinforcing member 5 is close to the inner surface of the frame 6. That is, the reinforcing member 5 is closer to the inside of the cabinet 1 than the fixing part 310 of the lower hinge 31.

[0098] The fastener 8 applies a pre-tightening force to connect the fixing part 310 of the lower hinge 31, the frame 6 and the reinforcing member 5 into a rigid whole, so that the force generated when the door 2 is opened or closed acts on the reinforcing member 5, thereby improving the deformation resistance of the lower hinge 31 and the frame 6 of the cabinet 1 at the connection point.

[0099] The reinforcing component 5 can be made of metal or other materials with a certain strength.

[0100] The mounting part 9 is provided with at least one second sliding groove on the side away from the back plate 7; the reinforcing member 5 is slidably inserted into the second sliding groove.

[0101] When installing the reinforcing member 5, simply align the end of the reinforcing member 5 with one end of the second slide groove, and then slide it along the second slide groove to quickly guide the reinforcing member 5 to the preset correct position corresponding to the fixing part 310 of the lower hinge 31, thereby improving the efficiency and convenience of the assembly process of the reinforcing member 5.

[0102] In one embodiment, the second slide groove extends vertically, that is, the second slide groove extends up and down along the height of the cabinet 1, and the reinforcing member 5 is slidably inserted into the second slide groove from bottom to top.

[0103] The mounting part 9 is further provided with a first stop bar and a second stop bar on the side away from the back plate 7, and the distance between the first stop bar and the second stop bar is adapted to the width of the reinforcing member 5.

[0104] On the side of the frame 6 away from the lower hinge 31, a first stop bar and a second stop bar are arranged side by side, and the distance between the first stop bar and the second stop bar is adapted to the width of the reinforcing member 5.

[0105] The first and second stop bars are configured as two rib structures that protrude from the side of the frame 6 away from the fixing part 310 of the lower hinge 31 and are arranged parallel to each other.

[0106] The spacing between the first and second stop bars is set to match the width of the reinforcing member 5, so that the two sides of the reinforcing member 5 along the width direction form good sliding contact with the inner surfaces of the first and second stop bars.

[0107] As the reinforcing member 5 slides upward, the two sides along the width direction always maintain contact with the inner surfaces of the first and second stop bars, forming a sliding connection.

[0108] In this application, the second slide groove restricts the reinforcement 5 from shifting in the lateral front-to-back direction, and the first and second stops restrict the reinforcement 5 from shifting in the lateral left-to-right direction.

[0109] The mounting part 9 passes through the upper surface of the frame 6 to form a mounting opening, and a second blocking member 61 protruding upward is provided on the periphery of the upper surface of the mounting opening.

[0110] An annular second shield 61, which surrounds the periphery of the mounting opening and protrudes vertically upward, is integrally formed on the frame 6 to effectively prevent condensation or dust from falling into the mounting opening.

[0111] The lower hinge 31 includes a hinge body and a first blocking portion 313 that extends laterally from the hinge body in a direction away from the upper hinge 32. The first blocking portion 313 blocks at least part of the second blocking member 61.

[0112] The lower hinge 31 also includes a first blocking portion 313 extending from the lower end of the first pivot portion 312 away from the first pivot portion 312. After the lower hinge 31 is assembled, the first blocking portion 313 blocks the upper edge of the mounting portion 9.

[0113] The first shielding part 313 is configured as a plate-like structure extending laterally from the lower end of the first pivot part 312 away from the first pivot part 312. After the hinge assembly 3 is assembled, the first shielding part 313 is used to shield the upper edge of the mounting part 9, that is, the first shielding part 313 shields the mounting opening of the mounting cavity. The first shielding part 313 can effectively prevent condensation or dust on the rear side of the door body 2 from entering the mounting cavity of the lower hinge 31, causing internal parts to rust or wear between parts due to impurities.

[0114] At least a portion of the rear side of the door body 2 is recessed toward the middle of the door body 2, exposing the mounting portion 9.

[0115] At least a portion of the rear side of the door body 2 is recessed toward the middle of the door body 2, and the lower hinge 31 includes a first pivot portion 312 pivotally connected to the upper hinge 32, the first pivot portion 312 being higher than the upper edge of the mounting portion 9.

[0116] When the door 2 closes the cabinet opening 4, the rear side of the door 2 is provided with a receiving part 21 that is partially or entirely recessed towards the middle of the door 2 to accommodate the hinge assembly 3.

[0117] The lower hinge 31 includes a first pivot portion 312 pivotally connected to the upper hinge 32, and the upper hinge 32 has a second pivot portion 321 pivotally connected to the lower hinge 31. The first pivot portion 312 and the second pivot portion 321 are pivotally connected via a pivot axis.

[0118] The first pivot portion 312 is higher than the upper edge of the mounting portion 9, and the second pivot portion 321 is also set to be higher than the upper edge of the mounting portion 9, along with the first pivot portion 312. The recessed receiving portion 21 provides space for the first pivot portion 312 and the second pivot portion 321 to accommodate and rotate, so that when the door 2 is opened or closed, the rear side of the door 2 will not interfere with the pivoting process of the hinge assembly 3. At the same time, it effectively reduces the size of the hinge assembly 3 protruding from the rear side of the back panel 7, increasing the packing capacity of the freezer 100 during transportation.

[0119] This application relates to a freezer 100, including a cabinet body 1 with a cabinet opening 4, a frame 6 disposed around the cabinet opening 4, and a door 2 covering the cabinet opening 4. The door 2 and the cabinet body 1 are pivotally connected by a hinge assembly 3. The hinge assembly 3 includes an upper hinge 32 and a lower hinge 31 pivotally connected to each other. The upper hinge 32 is connected to the door 2, and the lower hinge 31 is connected to the cabinet body 1. The cabinet body 1 includes a back panel 7 disposed on the rear side. The frame 6 includes a rear frame located on the rear side. The rear frame is provided with a mounting portion 9 that is partially recessed forward relative to the back panel 7. The mounting portion 9 and the back panel 7 form a mounting cavity. At least a portion of the lower hinge 31 is located within the mounting cavity. This application provides a mounting portion 9 recessed into the cabinet 1 on the rear frame, which together with the back panel 7 forms a mounting cavity for the lower hinge 31. At least part of the lower hinge 31 is hidden in the mounting cavity, which can effectively reduce the risk of damage to the lower hinge 31 and make the freezer 100 more aesthetically pleasing.
