Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a seal-free structure for the corners of the outer casing of a refrigerator. Background Technology

[0002] A refrigerator is a device used to store food. Different ingredients usually require different preservation methods, so it is necessary to store them separately. Multi-compartment refrigerators can adapt to the preservation needs of classified storage. The corner joints of the outer panels of traditional refrigerators usually need to be sealed with glue, sealant or other filling materials to prevent cold air leakage, moisture intrusion and thermal bridging effect inside the material. However, the sealing materials may age and crack over time, resulting in a decrease in sealing performance. Moreover, disassembly is difficult during maintenance and inconvenient to use.

[0024] Reference Figure 1-3 This utility model provides a sealing-free structure for the corners of the refrigerator's outer casing, including:

[0025] The installation unit 100 includes a housing 101, with an inner liner 102 inside the housing 101. A door panel 103 is rotatably connected to the front outer surface of the housing 101. Each of the four corners of the front outer surface of the housing 101 has a mounting groove 106. Both sides of the mounting groove 106 have slots 108. A mounting block 109 is located inside the mounting groove 106. One end of the mounting block 109 has a insertion groove 110. Both sides of the insertion groove 110 have sliding grooves 111. A locking block 112 is slidably connected inside the sliding groove 111. A fixing component 114 is located inside the insertion groove 110. Adjustable feet 105 are fixedly connected to the four corners of the lower surface of the housing 101. A sealing gasket 104 is fixedly connected to the inner outer edge of the door panel 103. Sealing blocks 115 are fixedly connected to the four corners of the inner surface of the door panel 103. The inner liner 102 has grooves 107 at each of its four corners on its outer surface. The interior of the grooves 107 fits snugly against the outer surface of the mounting block 109. The mounting grooves 106 and mounting blocks 109 ensure the stability and precision of the insertion process. The insertion grooves 110 of the mounting blocks 109 cooperate with the fixing components 114 to ensure the stability and sealing of the entire structure during long-term use. When the door panel 103 rotates, the sealing gasket 104 on its outer edge effectively seals the contact surface with the cabinet 101 to prevent cold air leakage. The four corner sealing blocks 115 fit snugly against the interior of the mounting grooves 106 to reduce rebound when the door panel 103 is closed, further improving the sealing performance. The four corner grooves 107 of the inner liner 102 fit snugly against the outer surface of the mounting blocks 109, enhancing the overall structural stability and facilitating installation.

[0026] The fixing component 114 includes a connecting plate 114a. A protrusion 114b is fixedly connected to one outer surface of the connecting plate 114a. The outer surface of the protrusion 114b fits into the interior of the insertion groove 110. A semi-circular protrusion is provided on the outer surface of the protrusion 114b. A pull ring 114c is rotatably connected to the other side of the connecting plate 114a. A placement groove 114d is formed on the front outer surface of the connecting plate 114a. The outer surface of the pull ring 114c is rotatably connected to the interior of the placement groove 114d. A finger groove is formed on one side of the placement groove 114d. The connecting plate 114a is tightly engaged with the insertion slot 110 via a protrusion 114b on one side. The semi-circular protrusion design of the protrusion 114b enhances its fixation with the insertion slot 110, preventing loosening or detachment due to external force. The other side of the connecting plate 114a is adjustable via a rotating pull ring 114c. The pull ring 114c, in conjunction with the placement slot 114d, allows it to be pulled out or retracted when needed, thereby adjusting the usage state of the fixing component 114. The design of the placement slot 114d allows the pull ring 114c to rotate freely within the slot, facilitating user operation of the fixing component 114 as needed. It also provides a convenient finger groove design, ensuring that users can easily grasp and operate the pull ring 114c.

[0027] Furthermore, the locking block 112 is T-shaped, with a return spring 113 fixedly connected to one outer surface of the locking block 112. One end of the return spring 113 is fixedly connected to the inside of the slide groove 111, one end of the locking block 112 is attached to the outer surface of the protrusion 114b, and the other end of the locking block 112 is attached to the inside of the locking groove 108. Through the action of the return spring 113, when the locking block 112 is pushed by the protrusion 114b, it enters the inside of the locking groove 108. When the fixing component 114 is removed, the return spring 113 quickly returns it to its original position, ensuring it remains in the correct position, thus enhancing the stability and safety of the overall sealing structure. One end of the locking block 112 is attached to the outer surface of the protrusion 114b, forming an effective fixing relationship, while the other end is tightly fitted to the inner wall of the locking groove 108, ensuring a tight connection between the mounting block 109 and the housing 101.

[0028] During use, the mounting block 109 is first inserted into the mounting groove 106, and then the fixing component 114 is inserted into the insertion groove 110. The protrusion 114b pushes the locking block 112 into the locking groove 108, thus fixing the mounting block 109 inside the housing 101, improving the convenience of use. When in use, one end of the sealing block 115 will fit against the outer surface of the fixing component 114, reducing the rebound when closing the door panel 103, thereby improving the sealing performance.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
