Description

Technical Field

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

[0002] A freezer is an electrical appliance that uses a refrigeration system to create a low-temperature environment for storing food, medicine, or other items requiring cold storage. Typically, the freezer cabinet and door are pivotally connected by hinges. In traditional freezer designs, the hinge, as a key component connecting the door and cabinet, is usually directly fixed to the side panel of the cabinet. However, due to the limited thickness and strength of the cabinet material, the long-term force and vibration generated by opening and closing the door can easily lead to deformation of the side panel or loosening of the hinge, thus affecting the door's sealing and operational stability. Utility Model Content

[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. In this application, the opening side of the door 2 of the freezer 100 is the front, which is the standing side of the user when operating the freezer 100. The rear wall of the cabinet 1, which is opposite to the front of the door 2, is the rear. The back panel 7 of the freezer 100 is located on the rear side of the cabinet 1.

[0035] The freezer 100 includes a cabinet body 1 with a 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 that are 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 lower hinge 31 includes a fixing part 311 that connects to the cabinet body 1. The freezer 100 also includes a frame 6, a reinforcing member 5, and a fastener 8. The frame 6 surrounds the periphery of the cabinet opening 4. The reinforcing member 5 and the fixing part 311 are located on opposite sides of the frame 6. The fastener 8 connects the fixing part 311, the frame 6, and the reinforcing member 5.

[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] A frame 6 is provided around the perimeter of the cabinet opening 4 on the outside of the cabinet body 1. The frame 6 extends horizontally along the perimeter of the cabinet opening 4 to form the contact surface between the door body 2 and the cabinet body 1.

[0038] 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 top or side of the door 2 and moves synchronously with the door 2. The lower hinge 31 includes a fixing part 311, 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 rotates smoothly on the cabinet 1.

[0039] The reinforcing member 5 and the fixing part 311 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 311 of the lower hinge 31 is on the outside, and the fixing part 311 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 311 of the lower hinge 31.

[0040] The fastener 8 applies a pre-tightening force to connect the fixing part 311 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.

[0041] The reinforcing component 5 can be made of metal or other materials with a certain strength.

[0042] A groove 61 is provided on the side of the mouth frame 6 away from the fixing part 311, and the reinforcing member 5 is slidably inserted into the groove 61.

[0043] Specifically, the slide 61 is located on the side of the frame 6 facing the inside of the cabinet 1, and the reinforcing member 5 is slidably inserted along the axial direction of the slide 61. The sliding range of the reinforcing member 5 depends on the length of the slide 61.

[0044] The reinforcing member 5 can slide along the axial direction of the groove 61 from bottom to top, from left to right, from right to left, or even from top to bottom.

[0045] When installing the reinforcing member 5, simply align the end of the reinforcing member 5 with one end of the slide groove 61 and then slide it along the slide groove 61 to quickly guide the reinforcing member 5 to the preset correct position corresponding to the fixing part 311 of the lower hinge 31, thereby improving the efficiency and convenience of the assembly process of the reinforcing member 5.

[0046] In one embodiment, the slide 61 extends vertically, that is, the slide 61 extends up and down along the height of the cabinet 1, and the reinforcing member 5 is slidably inserted into the slide 61 from bottom to top.

[0047] The reinforcing member 5 and the slide 61 are configured with a clearance fit to ensure that the reinforcing member 5 can slide freely in the vertical direction along the slide 61. At the same time, the slide 61 restricts the horizontal displacement of the reinforcing member 5 in the front-back direction.

[0048] The lower part of the frame 6 surrounds the perimeter of the cabinet opening 4 of the cabinet body 1. The lower end of the frame 6 usually has an opening that fits around the perimeter of the cabinet opening 4. The reinforcing member 5 slides into the slide groove 61 from bottom to top, eliminating the need for complicated alignment operations in the narrow space above the frame 6 and simplifying the assembly process of the reinforcing member 5.

[0049] An L-shaped fastener 62 is provided on the side of the mouth frame 6 away from the lower hinge 31. The L-shaped fastener 62 and the inner sidewall of the mouth frame 6 define a downward-facing sliding groove 61 for sliding the reinforcing member 5.

[0050] The L-shaped fastener 62 is configured as a right-angled or similar right-angled bent structure, including a horizontal arm 621 and a vertical arm 622 connected to each other; wherein, the horizontal arm 621 is connected to the inner wall of the frame 6, and the vertical arm 622 is connected to the end of the horizontal arm 621 away from the fixing part 311. In one embodiment, the horizontal arm 621 is set higher than the vertical arm 622, and the vertical arm 622 extends downward from the end of the horizontal arm 621 away from the fixing part 311 and is parallel to the inner wall of the frame 6. The L-shaped fastener 62 and the inner wall of the frame 6 together form a downward-opening sliding groove 61.

[0051] The cross-section of the chute 61 is U-shaped with the opening facing downwards.

[0052] A chamfer is provided at the entrance of the slide groove 61, that is, a chamfer is provided on the side of the lower end of the vertical arm 622 of the L-shaped fastener 62 facing the inner wall of the frame 6, and the chamfer gradually approaches the inner wall of the frame 6 from bottom to top; this is used to guide the reinforcing member 5 to slide accurately into the slide groove 61, thereby improving the assembly accuracy of the reinforcing member 5 and the frame 6.

[0053] The L-shaped fastener 62 is rigidly connected to the inner wall of the frame 6 to ensure the stability of the slide 61 and provide a stable sliding foundation for the pre-installation of the reinforcing member 5.

[0054] The frame 6 includes an upper frame 63 extending along the shape of the cabinet opening 4. The L-shaped fastener 62 includes a downwardly extending vertical arm 622. A reinforcing rib 64 is provided on the side of the vertical arm 622 away from the slide groove 61. The top of the reinforcing rib 64 is connected to the lower surface of the upper frame 63.

[0055] The upper frame 63 is a closed profile that extends along the outline of the cabinet opening 4 at the top of the frame 6. The inner sidewall of the upper frame 63 is perpendicular to the upper surface of the cabinet 1 and is in direct contact with the sealing strip of the door 2. The upper surface of the cabinet 1 is the upper edge of each sidewall of the cabinet 1.

[0056] The vertical arm 622 is a vertical extension of the L-shaped fastener 62. The reinforcing rib 64 is a plate-like structure with a trapezoidal or triangular cross-section. The reinforcing rib 64 is set in a vertical direction with its side attached to the outside of the vertical arm 622 away from the fixing part 311. The top of the reinforcing rib 64 extends upward to the lower surface of the upper frame 63 to form a stable support structure.

[0057] The length of the reinforcing rib 64 from top to bottom can be equal to the length of the vertical arm 622, or it can be set to be less than the length of the vertical arm 622.

[0058] The reinforcing rib 64 also includes an inclined side that extends from the outer side of the vertical arm 622 away from the fixing part 311 to the lower surface of the upper frame 63. The reinforcing rib 64 works in conjunction with the vertical arm 622 to make full use of the narrow space between the frame 6 and the cabinet 1. By arranging one side obliquely, the strength of the L-shaped fixing member 62 is maximized.

[0059] One of the reinforcing member 5 and the mouth frame 6 is provided with a fixing protrusion 65, and the other is provided with a limiting hole 51 corresponding to the fixing protrusion 65; the reinforcing member 5 is configured such that when the reinforcing member 5 is assembled on the mouth frame 6, the fixing protrusion 65 is located in the limiting hole 51.

[0060] Taking the example of the limiting hole 51 being located on the reinforcing member 5 and the fixing protrusion 65 being located on the frame 6, the cooperation relationship between the fixing protrusion 65 and the limiting hole 51 is explained. Of course, when the limiting hole 51 is located on the frame 6 and the fixing protrusion 65 is located on the reinforcing member 5, the cooperation relationship between the fixing protrusion 65 and the limiting hole 51 is the same as the following content, and will not be repeated.

[0061] The fixed protrusion 65 is a protruding structure integrally formed with the frame 6, and its cross-section can be set as circular, square, trapezoidal or other shapes.

[0062] The limiting hole 51 is a through hole or blind hole on the reinforcing member 5 that corresponds to the fixing protrusion 65, and its shape matches the cross section of the fixing protrusion 65.

[0063] The fixed protrusion 65 and the limiting hole 51 are positioned close to the lower end of the reinforcing member 5. When the reinforcing member 5 slides upward along the slide groove 61 to the preset highest position, the fixed protrusion 65 and the limiting hole 51 engage with each other to form an interlocking structure.

[0064] The fixing protrusion 65 engages with the limiting hole 51, preventing the reinforcing member 5 from sliding down longitudinally and preventing it from shifting laterally. Even if released, the reinforcing member 5 remains in the preset position, making installation easier.

[0065] In one application, the limiting hole 51 is a through hole that passes through the reinforcing member 5 along the thickness direction, and the thickness of the protruding fixing protrusion 65 is less than the depth of the limiting hole 51. That is, when the reinforcing member 5 is installed in place and the fixing protrusion 65 is located in the limiting hole 51, the fixing protrusion 65 is hidden in the limiting hole 51.

[0066] During the upward sliding process of the reinforcing member 5, the upper end of the reinforcing member 5 will first contact the fixed protrusion 65. By limiting the protrusion thickness of the fixed protrusion 65, the upward sliding process of the reinforcing member 5 can be ensured to be smoother.

[0067] It should be noted that the reinforcing member 5 is generally made of metal, while the mouth frame 6 is generally made of plastic. Setting the limiting hole 51 on the reinforcing member 5 instead of the mouth frame 6 can effectively ensure the strength of the limiting hole 51.

[0068] The vertical dimension of the limiting hole 51 is larger than the vertical dimension of the fixing protrusion 65.

[0069] The difference in vertical dimensions between the limiting hole 51 and the fixing protrusion 65 allows the fixing protrusion 65 to have a small space to move up and down within the limiting hole 51.

[0070] After the protrusion falls into the limiting hole 51 and before the bolt is tightened, the reinforcing member 5 can be finely adjusted in the vertical direction so that the reinforcing member 5 is in the best position to match the fixing part 311 of the lower hinge 31. That is to say, during the fine adjustment process before the reinforcing member 5 is fixed, the fixing protrusion 65 can contact the upper edge of the limiting hole 51, or the lower edge of the limiting hole 51, or be in the middle position of the limiting hole 51.

[0071] In addition, the vertical dimension of the limiting hole 51 is larger than that of the fixing protrusion 65, which can provide disassembly space when disassembling the reinforcing member 5, making it easier to disassemble the reinforcing member 5.

[0072] The frame 6 is provided with at least one first fixing hole 66, the reinforcing member 5 is provided with a second fixing hole 52 corresponding to the first fixing hole 66, and the fastener 8 is connected to the first fixing hole 66 and the second fixing hole 52 in sequence from back to front.

[0073] The first fixing hole 66 is a through hole set in the frame 6, and the second fixing hole 52 is set in the reinforcing member 5 and corresponds one-to-one with the first fixing hole 66. That is to say, the first fixing hole 66 and the second fixing hole 52 are on the same axis, and this axis is perpendicular to the plane where the back plate 7 is located, so that the fastener 8 can smoothly pass through the first fixing hole 66 and the second fixing hole 52.

[0074] The first fixing hole 66, the second fixing hole 52 and the fastener 8 achieve a stable connection between the three components: the lower hinge 31 fixing part 311, the frame 6 and the reinforcing part 5, ensuring the stability of the freezer door during long-term use.

[0075] The reinforcing member 5 includes a reinforcing member body and an annular platform portion 521 that surrounds the periphery of the second fixing hole 52 and protrudes from the reinforcing member body. The inner diameter of the annular platform portion 521 is adapted to the inner diameter of the second fixing hole 52, and the annular platform portion 521 extends the connection length between the second fixing hole 52 and the fastener 8.

[0076] The ring-shaped platform 521 is configured as an annular wall structure protruding from the main body of the reinforcing member, and the ring-shaped platform 521 can be integrally formed with the main body of the reinforcing member through a stamping process.

[0077] The annular portion 521 is configured to be concentric with the second fixing hole 52. The annular wall of the annular portion 521 wraps around the periphery of the second fixing hole 52. The inner diameter of the annular portion 521 is consistent with the inner diameter of the second fixing hole 52, forming a continuous and extended connecting inner wall. The height of the annular portion 521 is the extended connecting length.

[0078] Once the reinforcing member 5 is installed in place, the opening of the ring platform 521 or the opening of the second fixing hole 52 is completely aligned with the first fixing hole 66 of the frame 6.

[0079] By providing the ring-shaped portion 521, the thread of the fastener 8 engages with the inner wall thread within at least a portion of the height of the ring-shaped portion 521. The ring-shaped portion 521 increases the contact length between the two, increases the effective number of engagement turns, and effectively increases the stability of the connection between the fastener 8 and the reinforcing member 5.

[0080] In one embodiment, the annular portion 521 protrudes in a direction away from the opening frame 6.

[0081] The ring-shaped part 521 is designed to protrude from the main body of the self-reinforcing member toward the interior of the cabinet 1. That is to say, the second fixing hole 52 is located between the protruding ring-shaped part 521 and the frame 6.

[0082] After the reinforcing member 5 is installed in place by the guide structure such as the slide groove 61, the fastener 8 is inserted from the outside to the inside of the cabinet 1 into the fixing part 311 of the lower hinge 31 and continues forward, passing through the first fixing hole 66 on the frame 6, and then through the second fixing hole 52 of the reinforcing member 5 and finally connected to the ring platform part 521.

[0083] It should be noted that the fastener 8 in this application can be a bolt, a rivet, or a similar fastening structure, or other structures used for fixing. This application does not impose any specific limitations.

[0084] In another embodiment, the annular portion 521 protrudes toward the mouth frame 6 and is embedded in the first fixing hole 66.

[0085] In this embodiment, the main body of the ring-shaped portion 521, which is a self-reinforcing member, protrudes toward the opening frame 6.

[0086] The outer wall of the ring platform 521 and the inner wall of the first fixing hole 66 of the frame 6 form a tight clearance fit. The two achieve precise positioning and rigid connection through the embedded fit.

[0087] The protrusion height of the ring platform 521 is less than or equal to the thickness of the frame 6 material, so that when the front end of the ring platform 521 is inserted into the first fixing hole 66 of the frame 6 toward the lower hinge 31 fixing part 311, the side of the frame 6 near the lower hinge 31 fixing remains a flat contact end surface.

[0088] The ring-shaped portion 521 protrudes towards the opening frame 6 and is embedded in the first fixing hole 66, which shortens the connection path between the reinforcing member 5 and the fixing portion 311 of the lower hinge 31. Even when the fastener 8 is short, the fixing portion 311 of the lower hinge 31, the opening frame 6 and the reinforcing member 5 can still be stably connected.

[0089] The cabinet 1 includes an inner liner, an outer wall, and a foam layer filled between the inner liner and the outer wall. The reinforcing member 5 includes a first reinforcing part 53 connected to the cabinet and a second reinforcing part 54 bent from the first reinforcing part 53 away from the frame 6. The first reinforcing part 53 is connected to the frame 6. The second reinforcing part 54 is embedded in the foam layer.

[0090] The foam layer is a rigid polyurethane foam that fills the space between the inner liner and the outer wall. It serves as the insulation layer for the freezer. After curing, the foam layer possesses a certain structural strength and adhesive power, enabling it to bond the inner liner and outer wall together as a single unit. The reinforcing member 5 is configured as a first reinforcing part 53 and a second reinforcing part 54 connected together, forming an L-shaped corner structure. The first reinforcing part 53 is vertically arranged on the inner wall of the frame 6, parallel to the inner wall of the frame 6, and directly connected by fasteners 8. The second reinforcing part 54 extends laterally from the first reinforcing part 53 away from the lower hinge 31 and is embedded in the foam layer.

[0091] The second reinforcing part 54 is completely encased in a foam layer. Upon curing, the foam material adheres tightly to all surfaces of the second reinforcing part 54, forming extremely strong adhesion. This further increases the robustness and stability of the lower hinge 31 connected to the reinforcing member 5.

[0092] In one embodiment, the second reinforcing portion 54 is provided with at least one through hole 541 extending through the second reinforcing portion 54 in the thickness direction.

[0093] The second reinforcing part 54 may be provided with a plurality of through holes 541 extending along the thickness direction. The through holes 541 are embedded in the foam layer along with the second reinforcing part 54, so that the foam material fills the through holes and solidifies in the through holes to form a strong adhesion.

[0094] The through hole 541 of the second reinforcing part 54 can not only reduce the material used to make the reinforcing member 5 and reduce production costs, but also increase the contact area between the foam layer and the reinforcing member 5, thereby increasing the inner wall area of ​​the through hole 541 and significantly enhancing the bonding effect between the reinforcing member 5 and the foam layer, making the bond between the reinforcing member 5 and the foam layer more solid.

[0095] The first reinforcing part 53 and the second reinforcing part 54 are configured to have a rounded transition.

[0096] Specifically, at the intersection of the first reinforcing part 53 and the second reinforcing part 54, a smooth arc surface is provided for connection, and the three are connected to each other to form a continuous reinforcing member 5 as a whole.

[0097] The arc structure connection can evenly distribute the stress transmitted by the door 2 through the hinge assembly 3 on the arc surface, effectively eliminating the damage to the reinforcing component 5 caused by stress concentration and extending the service life of the freezer 100.

[0098] On the side of the frame 6 away from the lower hinge 31, a first stop bar 67 and a second stop bar 68 are arranged side by side, and the distance between the first stop bar 67 and the second stop bar 68 is adapted to the width of the reinforcing member 5.

[0099] The first stop bar 67 and the second stop bar 68 are configured as two rib structures that protrude from the side of the frame 6 away from the fixing part 311 of the lower hinge 31 and are arranged parallel to each other.

[0100] The spacing between the first stop bar 67 and the second stop bar 68 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 stop bar 67 and the second stop bar 68.

[0101] During the upward sliding of the reinforcing member 5, the two sides arranged along the width direction always maintain contact and cooperation with the inner surfaces of the first stop bar 67 and the second stop bar 68, forming a sliding connection.

[0102] In this application, the groove 61 restricts the reinforcement 5 from shifting in the lateral front-to-back direction, and the first stop 67 and the second stop 68 can restrict the reinforcement 5 from shifting in the lateral left-to-right direction.

[0103] The outer wall includes a back panel 7 located at the rear of the freezer 100, and the frame 6 includes a mounting portion 9 recessed inward toward the back panel 7. The mounting portion 9 and the back panel 7 form a mounting cavity for mounting the lower hinge 31. The reinforcing member 5 is disposed on the side of the mounting portion 9 away from the back panel 7.

[0104] The frame 6 includes a rear frame located on the rear side of the cabinet 1. Specifically, the mounting part 9 is configured such that a portion of the rear frame of the frame 6 is punched into the cabinet 1 to form a recessed mounting part 9. The recessed mounting part 9 and the back panel 7 together form a semi-closed mounting cavity for mounting the fixing part 311 of the lower hinge 31.

[0105] The reinforcing member 5 is located on the side of the mounting part 9 away from the back panel 7, the fixing part 311 of the lower hinge 31 is located in the mounting cavity, and the fastener 8 passes through the back panel 7, the fixing part 311 of the lower hinge 31, the mounting part 9 of the frame 6 and the reinforcing member 5 in sequence from the rear side of the cabinet 1 toward the inside of the cabinet 1.

[0106] This application uses the recessed back panel 7 and the recessed frame 6 of the freezer 100 to form the mounting cavity for the lower hinge 31, thus hiding the fixing part 311 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.

[0107] 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 mouth frame main body connected to the mounting part 9. The mouth frame main body 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.

[0108] The main body of the mouth frame 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 mouth frame and then bend downward to avoid the opening of the mounting part 9 for the insertion of the lower hinge 31.

[0109] 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 mouth frame body 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.

[0110] 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.

[0111] 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.

[0112] 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 recessed toward the middle of the door 2 to accommodate the hinge assembly 3.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] The first blocking part 313 is a plate-shaped structure that extends laterally from the lower end of the first pivot part 312 away from the first pivot part 312. When the hinge assembly 3 is assembled, the first blocking part 313 accurately blocks the upper edge of the mounting part 9 to effectively prevent condensation or dust from entering the mounting cavity of the lower hinge 31, causing internal parts to rust or wear between parts due to impurities.

[0117] This application relates to a freezer 100, which includes a cabinet body 1 having a 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 lower hinge 31 includes a fixing part 311 connected to the cabinet body 1. The freezer 100 also includes a frame 6, a reinforcing member 5, and a fastener 8 surrounding the periphery of the cabinet opening 4. The reinforcing member 5 and the fixing part 311 are located on opposite sides of the frame 6, and the fastener 8 connects the fixing part 311, the frame 6, and the reinforcing member 5. This application uses fasteners 8 to connect the lower hinge 31 fixing part 311, the frame 6 and the reinforcing member 5 inside the frame 6, so that the force generated when opening and closing the door acts on the reinforcing member 5, thereby improving the deformation resistance of the connection part between the lower hinge 31 and the frame 6 of the cabinet 1.
