Description

Technical Field

[0001] This utility model relates to the technical field of refrigerator structure, and in particular to a leak-proof structure for the drain pipe of a refrigerator body made of foam. Background Technology

[0002] A refrigerator is a household appliance that uses a refrigeration system to create a low-temperature environment inside the refrigerator, thereby extending the shelf life of food, medicine, and other items. It is widely used in homes, businesses, and medical settings. Its core principle is to use a compressor to drive the refrigerant to circulate in pipes, absorb heat from inside the refrigerator through the evaporator, dissipate heat to the outside through the condenser, and reduce heat exchange with the insulation layer to maintain the set low temperature inside the refrigerator.

[0003] The foaming process for the refrigerator body is a key technology for forming the insulation layer. Polyurethane raw materials are injected into the interlayer between the liner and the outer panel, causing it to react, expand, and solidify into closed-cell foam, which blocks heat transfer. To prevent leakage of foam at the drain pipe outlet, a sponge is attached to the surface of the drain pipe or a rubber sleeve is added to the surface of the drain pipe. This eliminates the gap between the drain pipe outlet and achieves the purpose of preventing foam leakage.

[0004] However, when refrigerator drain pipes are removed from the refrigerator, workers typically need to apply a sponge or add a rubber sleeve to the surface during production before installation. However, due to factors such as material handling causing deformation of the rubber sleeve and sponge, and production errors, poor sealing can occur at the drain pipe outlet, leading to leakage and impacting production efficiency. Furthermore, drain pipes are often designed with fixed dimensions, which can cause loose connections or assembly problems when connecting to larger or smaller external pipes, requiring additional parts and further increasing production steps and costs. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a leak-proof structure for the drain pipe of a refrigerator body made of foam. This structure aims to solve the problem that "when a refrigerator drain pipe is removed from the body, workers need to first apply a sponge to the surface of the drain pipe or add a rubber sleeve before installation. However, due to factors such as deformation of the rubber sleeve and sponge during material transportation and production errors, poor sealing may occur at the drain pipe outlet, leading to leakage of foam and affecting production efficiency. Furthermore, the drain pipe structure is mostly designed with fixed dimensions, which can easily cause loose connections or assembly failures when connecting to external pipes of larger or smaller specifications due to size mismatch, requiring additional replacement parts and further increasing production processes and costs."

[0036] Example 1

[0037] Reference Figures 1 to 6 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0038] The refrigerator body unit 100 and the leak-proof unit 200 are installed on the refrigerator body unit 100 and are used to prevent leakage of water from the refrigerator.

[0039] A connection adapter unit 300 is installed on the leak-proof unit 200 and is used to adapt to pipes of different specifications.

[0040] During use, the refrigerator main unit 100 provides a stable installation base, and the leak-proof unit 200 forms multiple seals to effectively block the leakage and impact of foaming liquid. This solves the problem of poor sealing caused by deformation of sponge or rubber sleeves in traditional structures, effectively optimizing the process and reducing material waste. Meanwhile, the connecting adapter unit 300 facilitates flexible adaptation to external pipes of different specifications, improving the versatility of the equipment. It also simplifies the assembly process, reduces labor and material costs, and significantly improves production efficiency.

[0041] Example 2

[0042] Reference Figures 1 to 6 This is the second embodiment of the present invention, which differs from the previous embodiment in that:

[0043] The refrigerator main unit 100 includes an outer box panel 101, a cabinet liner 102 and a large base 103 are fixedly installed inside the outer box panel 101, a back panel 104 is fixedly installed on one side surface of the outer box panel 101, and a drain pipe 105 is provided on the large base 103.

[0044] The outer panel 101 is connected to the back panel 104 to form a seamless rigid frame, providing excellent resistance to deformation. The connection between the inner box 102 and the large base 103 forms a stable support system. The whole is part of the refrigerator. The box-type base design of the large base 103 enhances the load-bearing capacity, and the drain pipe 105 installed on it optimizes the drainage path, effectively blocking the leakage of foaming liquid.

[0045] Specifically, the leak-proof unit 200 includes a water collection cover 201, which is fixedly installed at the top of the drain pipe 105. The water collection cover 201 is fixedly installed with the tank liner 102. An installation plate 202 is fixedly installed on the outer surface of the drain pipe 105, and the installation plate 202 is fixedly installed with the large base 103.

[0046] The water collection cover 201 is fixed to the tank liner 102 to form the first seal, which effectively intercepts the foaming liquid. The mounting plate 202 is fixed to the large base 103 to form the second layer of protection, which double blocks the leakage path. There is no need for traditional sponge or rubber sleeve, which reduces the sealing failure caused by material deformation, improves the reliability of leak prevention, simplifies the process, and improves production efficiency.

[0047] An interference fit structure is added to the drain pipe 105 near the outlet. The pressure generated by the foaming mold of the box during the mold closing process makes the interference fit structure of the drain pipe 105 tightly press against the periphery of the outlet of the drain pipe 105, thereby eliminating the gap between the drain pipe 105 and the outlet of the drain pipe 105 and achieving the purpose of preventing leakage of foam liquid.

[0048] Specifically, the connection adapter unit 300 includes multiple elastic elements 301, all of which are fixedly connected to the drain pipe 105. Each of the multiple elastic elements 301 has a positioning hole 302. An annular sleeve 303 is slidably installed on the drain pipe 105. Multiple positioning rods 304 are fixedly installed on one inner wall of the annular sleeve 303, and each of the multiple positioning rods 304 matches the corresponding positioning hole 302.

[0049] In use, the elastic element 301 deforms to adapt to pipes of different specifications, and the positioning rod 304 cooperates with the positioning hole 302 to ensure a stable connection. It can be compatible with pipes of different diameters without replacing parts, simplifying the adaptation process. The elastic element 301 fits tightly to the pipe to improve sealing and prevent leakage, greatly enhancing the adaptability of pipe connections.

[0050] Specifically, when connecting a smaller pipe, the pipe is inserted into the drain pipe 105. The smaller pipe has a groove on its outside that connects to the elastic element 301. A relatively forceful upward lift causes the groove to mate with the corresponding elastic element 301. Simultaneously, the sliding outer annular sleeve 303 moves downward, causing multiple positioning rods 304 to connect with the positioning holes 302, bringing one side of the elastic element 301 into contact with the inner elastic element 301 and securing it, ensuring a stable installation of the smaller pipe. When connecting a larger pipe, it is fitted onto the drain pipe. Outside of 105, the groove inside the large pipe is adapted to connect with the elastic element 301 on the outside. Then, the annular sleeve 303 is connected to the large pipe, and multiple positioning rods 304 are connected to the positioning holes 302 to tighten the elastic element 301 on the outside and prevent the large pipe from loosening. The top surface of the large pipe is provided with a connection hole that communicates with the groove, which can be adapted to connect according to the usage requirements. At least two types of connecting pipes adapted to the drain pipe 105 can be connected. The large pipe and the small pipe are not shown in the figure. They are existing mature pipe connection technologies and will not be described in detail in this article.

[0051] Example 3

[0052] Reference Figures 1 to 6 This is the third embodiment of the present invention, which differs from the previous embodiment in that:

[0053] Multiple reinforcing plates 2021 are fixedly installed on the top surface of the mounting plate 202, and multiple stabilizing plates 2022 are fixedly installed on the bottom surface of the mounting plate 202. The multiple reinforcing plates 2021 and stabilizing plates 2022 are all fixedly installed with the drain pipe 105.

[0054] The reinforcing plate 2021 and the stabilizing plate 2022 fix the drain pipe 105 from both the top and bottom, enhance the connection between the mounting plate 202 and the drain pipe 105, prevent shaking and deformation during drainage, and improve the overall structural stability.

[0055] Specifically, the water collection cover 201 is funnel-shaped, and one side surface of the water collection cover 201 forms a pressure surface, which faces the outlet of the drain pipe 105.

[0056] The funnel-shaped water collection cover 201 efficiently gathers water flow, with the pressure surface facing the outlet. It fits tightly during foaming, strengthening the seal and preventing leaks, thus improving drainage and leak prevention performance.

[0057] Specifically, the drain pipe 105 is installed vertically, with its axis set at a right angle to the horizontal plane, and large and small pipes can be connected to the drain pipe 105.

[0058] Vertical installation utilizes gravity for smooth drainage and prevents water accumulation; its adaptability to pipe sizes enhances connection flexibility and expands its applicability.

[0059] Specifically, the large base 103 has mounting holes, and one side of the mounting hole is concave.

[0060] The recessed design of the mounting holes on the large base 103 fits the drain pipe components to enhance sealing and ensures precise positioning to prevent displacement.

[0061] Specifically, the edges of multiple elastic elements 301 are all chamfered, and multiple elastic elements 301 abut against the corresponding positioning rods 304.

[0062] When in use, the edge of the elastic element 301 is chamfered to facilitate the quick insertion of the pipe, and it can abut against the positioning rod 304 to deform or tighten it.

[0063] Example 4

[0064] Reference Figures 1 to 6 This is the fourth embodiment of the present invention, which differs from the previous embodiment in that:

[0065] This embodiment provides a method for preventing leakage of the drain pipe of a refrigerator body made of foam. This method is applicable to the leak-proof structure of the drain pipe of a refrigerator body made of foam described in any one of embodiments 1-3 above. The method specifically includes:

[0066] During use, the main body unit 100 of the refrigerator builds a basic frame, the outer box panel 101 fixes the inner liner 102 and the large base 103, the back panel 104 closes one side to form a cavity, the mounting holes of the large base 103 provide positioning support for the drain pipe 105, the drain pipe 105 is installed in the vertical direction, and the funnel-shaped water collection cover 201 at the top is fixed to the inner liner 102, which can efficiently collect the defrosting water in the inner liner 102. Its pressure surface faces the outlet of the drain pipe 105, and it fits tightly with the inner liner 102 during the foaming process, initially blocking the foaming liquid from seeping in.

[0067] Meanwhile, the drain pipe 105 is tightly connected to the large base 103 through the mounting plate 202, forming a secondary seal. Combined with the shape design of the concave mounting hole of the large base 103, it further prevents the foaming liquid from leaking from the gap. When it is necessary to connect an external pipe, it is adapted to the size of the external pipe. The larger pipe is connected to the outer elastic element 301, and the annular sleeve 303 on the drain pipe 105 is slid, so that the positioning rod 304 on the inner wall is inserted into the positioning hole 302 of the corresponding elastic element 301. The elastic element 301 is deformed by the abutment of the positioning rod 304. The chamfered edge design facilitates the insertion of the pipe. After deformation, the elastic element 301 tightly wraps the external pipe, realizing the sealing adaptation of different pipe diameters and ensuring that the drainage path is unobstructed and leak-free.

[0068] 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.
