Description

Technical Field

[0001] This utility model relates to the field of freezer technology, specifically to a foam support mechanism for a freezer body. Background Technology

[0002] A freezer, also called a refrigerator, is a device used to preserve food and other items at low temperatures. There are two main types: household and commercial. Commercial freezers are used in restaurants, bars, food processing plants, and supermarkets.

[0003] The basic function of a freezer is refrigeration, maintaining a suitable low temperature inside. A refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or thermostatic expansion valve, and an evaporator. The refrigerant is a liquid that boils at low pressure and low temperature, absorbing heat during boiling. The refrigerant circulates continuously in the refrigeration system. The compressor increases the gas pressure of the refrigerant, creating liquefaction conditions. As it passes through the condenser, it condenses and releases heat. Then, as it passes through the capillary tube, its pressure and temperature decrease, and finally, as it passes through the evaporator, it boils and vaporizes, absorbing heat. Modern refrigerators also utilize refrigeration diodes, which have no complex mechanical devices, but are less efficient and are used in smaller refrigerators.

[0004] The cabinet is composed of structural and insulation materials, forming a space for food storage and preventing heat transfer between the inside and outside. The cabinet generally includes an outer shell, an inner liner, and an insulation layer. The insulation layer is a foamed layer, filled inside the outer shell to support the inner shell. In existing freezer structures, during the glue injection process, there is an internal connection structure between the inner and outer shells. This allows the inner shell to easily wobble inside the outer shell, affecting the internal space dimensions and the accuracy of the connection between the inner and outer shells. Therefore, a foamed support mechanism for the freezer cabinet is proposed. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments.

[0006] In view of the problems existing in the above and / or existing foam support mechanisms for refrigerator bodies, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a foam support mechanism for a freezer body. The inner shell is suspended and fixed inside the outer shell. After the glue is injected, the foam expands in the gap between the outer shell and the inner shell, filling the gap between the outer shell and the inner shell to form a foam support layer, which supports the inner shell and prevents the inner shell from shaking inside the outer shell during glue injection, thus affecting the connection effect.

[0008] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0009] A foam support mechanism for a freezer cabinet, comprising:

[0010] The outer shell includes an outer shell body, a sleeve, and a limiting groove. The sleeve is provided at the bottom of the inner cavity of the outer shell, and the limiting groove is provided on the side wall of the inner cavity of the outer shell.

[0011] An inner liner is disposed within the outer shell. The inner liner includes an inner shell, a top cover, a plug rod, and a slide rod. The top of the inner shell is provided with a top cover that fits into the inner cavity of the outer shell. The bottom of the inner shell is provided with a plug rod that connects to a sleeve.

[0015] In a preferred embodiment of the refrigerator body foam support mechanism described in this utility model, when the slide rod slides into the slide groove, the lower end of the elastic sheet is stuck on the upper end of the slide rod.

[0016] As a preferred embodiment of the foam support mechanism for a freezer body described in this utility model, the sliding groove is a U-shaped groove with an open top.

[0017] As a preferred embodiment of the refrigerator body foaming support mechanism described in this utility model, the sleeves are evenly distributed at the bottom of the inner cavity of the outer shell, and the limiting grooves are evenly distributed on the side wall of the inner cavity of the outer shell.

[0018] As a preferred embodiment of the refrigerator body foaming support mechanism described in this utility model, wherein: when the inner shell and the outer shell are connected, the top of the top cover is flush with the top of the outer shell.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This utility model provides a foam support mechanism for a freezer body. The inner shell is suspended and fixed within the outer shell. After adhesive injection, the foam expands at the gap between the outer and inner shells, filling the space between them to form a foam support layer. This supports the inner shell and prevents it from shaking within the outer shell during adhesive injection, which could affect the connection. Please refer to [link to relevant documentation]. Figures 1-5 It includes: outer shell 100, inner liner 200 and foam support layer 300.

[0032] The outer casing 100 includes an outer casing 110, a sleeve 120 and a limiting groove 130. The sleeve 120 is provided at the bottom of the inner cavity of the outer casing 110, and the limiting groove 130 is provided on the side wall of the inner cavity of the outer casing 110.

[0033] Among them, the sleeve 120 is a round sleeve, and the limiting groove 130 is a U-shaped groove with an open top.

[0034] The inner liner 200 is disposed inside the outer shell 110. The inner liner 200 includes an inner shell 210, a top cover 220, a plug rod 230 and a slide rod 240. The top of the inner shell 210 is provided with a top cover 220 that fits into the inner cavity of the outer shell 110. The bottom of the inner shell 210 is provided with a plug rod 230 that is connected to the sleeve 120. The side wall of the inner shell 210 is provided with a slide rod 240 that is connected to the limiting groove 130.

[0035] The bottom of the inner shell 210 is inserted into the sleeve 120 via a rod 230, which supports the bottom of the inner shell 210. The sliding rod 240 is embedded in the limiting groove 130, so that the inner shell 210 is suspended and fixed inside the outer shell 110, thus fixing the inner shell 210.

[0036] A foam support layer 300 is filled between the outer shell 110 and the inner shell 210. The outer shell 110 has a round hole for injecting glue. Foam glue is injected into the space between the outer shell 110 and the inner shell 210 through the round hole to form the foam support layer 300, which supports the inner shell 210.

[0037] Since the expanding foam will expand, the expanding foam will lift up the inner shell 210 and affect the structural connection. Therefore, the limiting groove 130 includes a sliding groove 131, a storage groove 132 and an elastic sheet 133. The sliding groove 131 has storage grooves 132 on both sides inside, and the storage groove 132 has an elastic sheet 133 at the top.

[0038] In its natural state, the lower end of the elastic sheet 133 faces the center of the slide groove 131. During the connection process, the slide rod 240 slides down into the slide groove 131. When the slide rod 240 slides down and contacts the elastic sheet 133, it squeezes the elastic sheet 133, causing the elastic sheet 133 to move into the receiving groove 132. Finally, the elastic sheet 133 is stored in the receiving groove 132 without affecting the slide rod 240 from continuing to slide down. When the slide rod 240 slides down to the bottom of the slide groove 131, the elastic sheet 133 pops out from the receiving groove 132. When the slide rod 240 slides into the slide groove 131, the lower end of the elastic sheet 133 is stuck on the upper end of the slide rod 240.

[0039] To achieve stable support for the inner shell 210, the sleeve 120 is evenly distributed at the bottom of the inner cavity of the outer shell 110, and the limiting groove 130 is evenly distributed on the side wall of the inner cavity of the outer shell 110, providing uniform support force.

[0040] When the inner shell 210 is connected to the outer shell 110, the top of the top cover 220 is flush with the top of the outer shell 110, ensuring the accuracy of the structural connection.

[0041] In practical use, the bottom of the inner shell 210 is inserted into the sleeve 120 via the insert rod 230, which supports the bottom of the inner shell 210. The slide rod 240 is embedded in the limiting groove 130, so that the inner shell 210 is suspended and fixed in the outer shell 110, thus fixing the inner shell 210 and preventing it from shaking in the outer shell 110 during glue injection, which would affect the connection effect. When the slide rod 240 slides down to the bottom of the slide groove 131, the elastic piece 133 pops out from the receiving groove 132, so that when the slide rod 240 slides into the slide groove 131, the lower end of the elastic piece 133 is stuck in the upper end of the slide rod 240, preventing the inner shell 210 from moving when the foam expands.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
