[0017] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. In the following description relating to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms “first,” “second,” and similar terms used in this specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. “A plurality of” means two or more.

[0018] Unless otherwise stated, the orientation or positional relationship indicated by "top", "bottom", and "circumferential" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0019] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. Furthermore, "connection" should be interpreted broadly; for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0020] This application provides a refrigeration device, which includes an inner liner assembly 1 and a housing. The inner liner assembly 1 is disposed within the housing and includes a grounding member 12. The grounding member 12 extends from the outside of the sheet metal inner liner 11 in a direction away from the sheet metal inner liner 11, and is located between the sheet metal inner liner 11 and the housing. By extending the grounding member 12 from the sheet metal inner liner 11, it is possible to avoid directly drilling a grounding bolt 122 on the sheet metal inner liner 11 for grounding, which would damage the paint surface of the sheet metal inner liner 11 and thus avoid unstable grounding effect. In addition, by placing the grounding member 12 between the sheet metal inner liner 11 and the housing, and not exposing it to the outside, the possibility of corrosion of the grounding member 12 can be reduced.

[0021] In one embodiment, the refrigeration equipment further includes a foam layer disposed between the sheet metal inner liner 11 and the housing, with the grounding component 12 located within the foam layer. The placement of the grounding component 12 within the foam layer reduces its contact with air and moisture, thereby further preventing corrosion and improving the stability of the grounding.

[0022] It should be noted that the refrigeration equipment can be a refrigerator, freezer, wine cabinet, or other equipment whose inner liner components 1 need to be grounded. The above is not restrictive and can be configured according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0023] To further clarify the configuration of the grounding element 12 on the inner liner assembly 1, the inner liner assembly 1 will be described separately below.

[0024] refer to Figures 1 to 6 This application provides an inner liner assembly 1, which includes a sheet metal inner liner 11 and a grounding member 12. The grounding member 12 extends from the outside of the sheet metal inner liner 11 in a direction away from the sheet metal inner liner 11. The grounding member 12 extends from the sheet metal inner liner 11 and is connected to a grounding wire, thereby achieving grounding of the sheet metal inner liner 11. This eliminates the need for direct nailing to the sheet metal inner liner 11 for grounding. Therefore, the grounding member 12 avoids damage to the paint surface of the sheet metal inner liner 11 caused by nailing. It also prevents unstable grounding caused by corrosion of the paint surface due to paint damage.

[0025] In one embodiment, combined with Figures 2 to 4 The grounding component 12 includes a conductive plate 121 and a grounding bolt 122. The conductive plate 121 extends from the outside of the sheet metal inner liner 11 in a direction away from the sheet metal inner liner 11. The conductive plate 121 is provided with a first mounting hole 1211, and the grounding bolt 122 is fixed to the first mounting hole 1211. The conductive plate 121 can be integrally formed with the sheet metal inner liner 11, thereby saving manufacturing process. Connecting the grounding bolt 122 to the conductive plate 121 can avoid the grounding bolt 122 being directly fixed to the sheet metal inner liner 11 and causing damage to the sheet metal inner liner 11.

[0026] It should be noted that, in addition to being connected to the grounding wire via the grounding bolt 122, the grounding component 12 can also be connected to the grounding wire in other ways. For example, the grounding wire can be connected to the grounding component 12 via a plug-in terminal. The above is not restrictive and can be configured according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0027] In one embodiment, the first mounting hole 1211 is interference-fitted with the grounding bolt 122, thereby ensuring that the grounding bolt 122 is securely fastened to the conductive plate 121 without loosening.

[0028] It should be noted that the grounding bolt 122 can also be connected to the first mounting hole 1211 by thread. The above is not restrictive and can be set according to the needs of those skilled in the art. All of the above are within the protection scope of this application.

[0029] In one embodiment, combined with Figure 2 , Figure 5 , Figure 6 The inner liner assembly 1 also includes a terminal block 13, which is used to install wiring terminals 15. The terminal block 13 is provided with a slot 131, which is fitted onto a conductive plate 121 so that the conductive plate 121 extends out from the slot 131. The terminal block 13 is used to install wiring terminals 15 of refrigeration equipment, such as fan terminals, lamp assembly terminals, etc., inside the refrigeration equipment. The terminal block 13 is set on the sheet metal inner liner 11. When the terminal block 13 is provided with the slot 131, the slot 131 cooperates with the conductive plate 121. The conductive plate 121 has a limiting effect on the slot 131, thereby preventing the terminal block 13 from moving and ensuring that the terminal block 13 is stably set on the sheet metal inner liner 11. At the same time, the conductive plate 121 also has a guiding effect on the terminal block 13, thereby enabling the terminal block 13 to be quickly installed on the sheet metal inner liner 11.

[0030] In one embodiment, the combination continues. Figure 2 , Figure 5 , Figure 6 The terminal block 13 is also provided with a support plate 132, which is located at the edge of the slot 131 and is in contact with the grounding member 12. The support plate 132 on the terminal block 13 is in contact with the conductive plate 121, thereby increasing the contact area between the conductive plate 121 and the terminal block 13 and preventing the conductive plate 121 from breaking due to excessive stress at the slot 131 of the terminal block 13.

[0031] In one embodiment, the combination continues. Figures 2 to 6 The support plate 132 is provided with a second mounting hole 1321. One end of the grounding bolt 122 can pass through the first mounting hole 1211 and the second mounting hole 1321, and the other end of the grounding bolt 122 abuts against the conductive plate 121. By connecting the conductive plate 121 to the support plate 132 through the grounding bolt 122, the stability of the connection between the conductive plate 121 and the terminal clamp plate 13 can be further ensured, thereby further ensuring that the terminal clamp plate 13 is stably fixed to the sheet metal inner liner 11.

[0032] In one embodiment, reference is made to... Figure 2The inner liner assembly 1 also includes a grounding nut 14, which is screwed onto the first end of the grounding bolt 122 and fits against the support plate 132. The screwed connection between the grounding nut 14 and the grounding bolt 122 further ensures a tight connection between the grounding bolt 122 and the conductive plate 121. Simultaneously, the connection between the conductive plate 121 and the support plate 132 via the grounding bolt 122 and the grounding nut 14 also ensures that the terminal block 13 is stably fixed to the sheet metal inner liner 11 via the conductive plate 121.

[0033] It should be noted that the grounding bolt 122 can connect the support plate 132 and the conductive plate 121 by screwing it into the grounding nut 14. Alternatively, the grounding bolt 122 can be configured to be interference-fitted with the first mounting hole 1211 and the second mounting hole 1321 to securely connect with the support plate 132 and the conductive plate 121. Alternatively, the grounding bolt 122 can be threaded into both the first mounting hole 1211 and the second mounting hole 1321 to securely connect with the support plate 132 and the conductive plate 121. All of the above are within the scope of protection of this application.

[0034] In one embodiment, reference is made to... Figure 6 The support plate 132 has a nut mounting position 1322 on the side facing the grounding nut 14. The nut mounting position 1322 surrounds the second mounting hole 1321 and is used to accommodate the grounding nut 14. The nut mounting position 1322 can accommodate the grounding nut 14, ensuring the stability of the connection between the grounding bolt 122 and the grounding nut 14.

[0035] In one embodiment, multiple nut mounting positions 1322 are provided, each corresponding to a different size of grounding nut 14. Different nut mounting positions 1322 correspond to different sizes of grounding nuts 14, thus enabling the support plate 132 to accommodate the installation of grounding nuts 14 of different specifications. Since different specifications of sheet metal inner liner 11 correspond to different sizes of grounding nuts 14, the terminal block 13 with multiple nut mounting positions 1322 can also accommodate sheet metal inner liner 11 of different specifications.

[0036] In one embodiment, the terminal block 13 may be made of insulating material and have a conductive layer plated on its surface, thereby ensuring good electrical connection performance of the terminal block 13.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
