Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator structures, in particular to a refrigerator maintenance structure. Background Art

[0002] The internal structure of the ultra-low temperature freezer storage box is sophisticated, and there are some easily damaged parts, such as the evaporator capillary tube. The evaporator capillary tube is a component used to throttle the refrigerant in the compressor refrigeration cycle system. It plays a key refrigeration role and is part of the evaporator of the refrigeration system. It is generally made of copper tubes. When impurities appear inside the box pipes, the impurities will be captured by the evaporator capillary tube filter, which will cause pipeline failure. At this time, the evaporator capillary tube needs to be replaced. For easy maintenance, most refrigerators will place the evaporator capillary tube and filter outside the box foam layer. However, since the required temperature of the evaporator capillary tube during operation is very low, the heat exchange rate between the evaporator capillary tube placed outside the foam layer and the outside is too large, and additional heating and insulation equipment needs to be added to the outside of the evaporator capillary tube, which will increase the production cost of the refrigerator.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the present invention and does not mean that the above content is the closest prior art. Utility Model Content

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-8 The maintenance structure of a refrigerator shown in the figure includes a refrigerator body 1, and an inwardly recessed mounting groove 11 is provided on the back of the refrigerator body 1 for placing the evaporator capillary and its filter. The outside of the mounting groove 11 is covered with a back panel 12, and the back panel 12 is mounted on the refrigerator body 1 by screws 13; the interior of the back panel 12 is hollow and is provided with an inner panel 14, and a foaming cavity 15 for accommodating foaming material is formed between the inner panel 14 and the back panel 12. The mounting groove 11 is recessed inward so that its periphery is surrounded by a foaming layer, and the foaming cavity 15 is provided inside the back panel 12 so that it can be filled with foaming material. Therefore, when the evaporator capillary and its filter are placed in the mounting groove 11, the foaming material will provide them with good thermal insulation effect, so that they can maintain normal working temperature without setting up additional heating equipment.

[0027] In one embodiment, a fixing plate 2 is provided on the side wall of the foaming cavity 15, and a threaded rod 21 movably connected to the inner buckle plate 14 is provided on the fixing plate 2, and an adjustment cap 22 is threadedly connected to the threaded rod 21; when the inner buckle plate 14 is installed in the back plate 12, the adjustment cap 22 is located on the side of the inner buckle plate 14 away from the foaming cavity 15. By rotating the adjustment cap 22, the installation position of the inner buckle plate 14 can be adjusted, thereby changing the size of the space between the inner buckle plate 14 and the installation groove 11, and then the accommodating space can be flexibly adjusted according to the actual installation conditions of the components inside the installation groove 11.

[0028] In one embodiment, an inner frame plate 3 is provided inside the mounting groove 11, and a movable groove 31 is formed between the four side walls of the mounting groove 11 and the inner frame plate 3. A sealing plate 32 that is movably inserted into the movable groove 31 is provided on the back plate 12. When the back plate 12 is buckled on the outside of the mounting groove 11, the sealing plate 32 is movably inserted into the movable groove 31, so that the connecting part between the back plate 12 and the mounting groove 11 can be extended, thereby increasing the flow channel for external air to enter the interior of the mounting groove 11 through the connecting position, reducing the heat exchange effect with the outside world, and improving the thermal insulation performance.

[0029] In one embodiment, a support plate 4 with limited sliding is provided in the movable groove 31, and a spring 41 is provided between the support plate 4 and the bottom side wall of the installation groove 11. When the partition plate 32 is movably inserted into the movable groove 31, it will abut against the support plate 4, and as it goes deeper into the movable groove 31, the abutment between the partition plate 32 and the support plate 4 becomes tighter, thereby further improving the sealing of the connecting part.

[0030] In one embodiment, a rubber pad 5 is provided at one end of the support plate 4 away from the spring 41. The provision of the rubber pad 5 allows the contact portion between the sealing plate 32 and the support plate 4 to be completely tight, isolating the entry of air to the greatest extent.

[0031] In one embodiment, a side panel 6 for the screws 13 to be movably connected is provided on the outer edge of the back panel 12, and a hook 61 is rotatably provided on the side panel 6. A buckle column 62 for the hook 61 to be engaged is provided inside the refrigerator body 1, and a limit baffle 63 is provided on the end of the buckle column 62 away from the refrigerator body 1. Since the back panel 12 is buckled and covered on the outside of the installation slot 11 in a direction perpendicular to the ground, the hook 61 is provided. After the back panel 12 is installed, the hook 61 is rotated to engage with the buckle column 62 to ensure that when the screws 13 on the back panel 12 are subsequently removed, the back panel 12 will not fall directly without the staff holding it with their hands, thereby facilitating the staff's disassembly and assembly work. The setting of the limit baffle 63 ensures that when the back panel 12 is disassembled and assembled, the back panel 12 will not directly pop out and fall under the action of the spring 41, thereby improving the convenience of disassembly and assembly.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
