Description

Technical Field

[0001] This utility model relates to the field of refrigerator interior panel technology, and in particular to an aluminum-coated HIPS refrigerator interior panel. Background Technology

[0002] The interior panel of a refrigerator is called the refrigerator liner. Currently, refrigerator liner materials are divided into two types: plastic liners, such as HIPS, and metal liners, such as aluminum and stainless steel. Plastic liners have the advantages of relatively low price, ease of processing, and light weight, but their heat transfer is relatively poor. Metal liners are the opposite of plastic liners; their advantages are good heat transfer, but their disadvantages are relatively high price, difficulty in molding, and heavier weight. Currently, over 95% of refrigerator liners in the industry are made of plastic. High-impact polystyrene (HIPS) is one of the main raw materials for refrigerator liner production in my country, possessing excellent water resistance and chemical corrosion resistance.

[0003] Most existing HIPS refrigerator interior panels are integrally molded using a hot-melt injection molding process and then installed inside the refrigerator. However, due to the poor heat transfer performance of HIPS refrigerator interior panels, ice and frost are prone to form inside the refrigerator after long-term use. In addition, when HIPS refrigerator interior panels are sealed, items placed inside can easily produce different odors that are difficult to handle. Therefore, there is a need to design an aluminum-coated HIPS refrigerator interior panel to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an aluminum-coated HIPS refrigerator interior panel.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A HIPS refrigerator interior panel with aluminum film coating includes an interior panel comprising a HIPS layer and an aluminum film layer. The aluminum film layer is disposed on the inner surface of the HIPS layer. An inner groove is provided at the bottom inner side of the interior panel, and a cover plate is provided at the top of the inner groove. A plurality of vent holes are equidistantly arranged at the top of the cover plate. The HIPS layer is formed by melt injection molding, and the aluminum film layer is formed by coating and curing. A locking device is provided at the bottom inner side of the interior panel. The locking device includes a housing and a locking post. The housing is fixedly connected to the middle of the rear bottom of the cover plate. A locking opening is provided in the middle of the locking post. A rotating post is fixedly connected to the inner side of the housing. A locking block is rotatably connected to the middle of the rotating post. A spring is provided at the bottom of the locking block. A pressing block is slidably connected to the inner side of the housing. A support block is provided at the bottom of the locking post.

[0007] The above technical solution increases the heat conduction efficiency of the HIPS layer by setting an aluminum film layer on the inner side of the HIPS layer, which is also easier to manufacture and reduces manufacturing costs. By setting an inner groove and cover plate on the inner bottom of the interior panel, odor-removing items can be placed inside the inner groove and the cover plate can be used to eliminate different odors generated by the placed items through the ventilation holes.

[0008] Furthermore, the cover plate is made of 2mm thick polystyrene material, and the diameter of the vent hole is 4mm;

[0009] The above technical solutions increase the convenience of use and reduce the cost of replacement when the cover is damaged.

[0010] Furthermore, handle grooves are provided in the middle of both the left and right sides of the cover plate;

[0011] The above technical solution facilitates the lifting of the cover plate.

[0012] Furthermore, the thickness of the HIPS layer is 3 cm;

[0013] The above technical solutions prevent the interior trim panel from losing too much temperature due to thin layers, thus reducing the cooling effect, while also preventing the manufacturing difficulties caused by thick layers.

[0014] Furthermore, the interior trim panel has several fixing grooves equidistantly arranged on both the left and right sides, and each fixing groove has an embedded metal strip fixedly connected inside.

[0015] The above technical solution facilitates the installation of embedded metal strips by setting fixing grooves on the left and right sides of the interior panel. The embedded metal strips increase the rate of heat conduction to the interior panel and prevent the loss of cold air.

[0016] Furthermore, the upper inner side of the interior panel is provided with several raised points at equal intervals, and the shape of the raised points is a semi-circle with a diameter of 1cm;

[0017] The above technical solution, by setting raised points, facilitates the increase of surface area on the upper inner side of the interior panel, and at the same time increases the area of ​​the aluminum film layer, preventing ice and frost from forming on the top. Even if ice or frost forms, the raised points make the ice or frost layer uneven, which is convenient for quick cleaning.

[0018] Furthermore, a mounting groove is provided on the upper rear side of the interior panel, and several support strips are provided on the left and right sides of the inner side of the interior panel.

[0019] The above technical solution facilitates the placement of the refrigerator's internal lighting, allowing for sufficient space to be allocated during manufacturing, while the support strip facilitates the support of the refrigerator's internal shelves.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, firstly, an aluminum-coated film layer is set on the inner side of the HIPS layer of the interior panel, which increases the heat conduction efficiency of the HIPS layer and facilitates manufacturing, reducing manufacturing costs. Secondly, by setting an inner groove and cover plate on the inner bottom of the interior panel, odor-removing items can be placed inside the inner groove and covered by the cover plate. Different odors generated by the placed items are eliminated through the ventilation holes, increasing convenience. Finally, by setting fixing grooves on the left and right sides of the interior panel, it is easy to install the embedded metal strip. The embedded metal strip increases the rate of heat conduction to the interior panel and prevents cold air loss. By covering the inner surface of the HIPS interior panel after manufacturing the HIPS interior panel, the manufacturing process is simple. The combination of HIPS interior panel and aluminum-coated metal not only solves the shortcomings of poor heat transfer effect of plastic inner liner and high price and difficult molding of metal inner liner in the prior art.

[0022] 2. In this utility model, the locking device allows the cover plate to be locked and fixedly connected to the upper part of the inner groove. During use, the locking post at the bottom of the cover plate presses down on the locking block, causing the locking block to rotate downwards on the rotating post. The front end of the locking block engages with the locking hole, causing the locking block to reset and the cover plate to be locked and fixed. To unlock, simply press down on the pressing block, causing it to slide downwards inside the outer shell and push down on the rear end of the locking block. The locking block compresses the spring, causing the locking block to separate from the locking hole. When the pressing block is released, the spring resets, causing the locking block to reset. This method is simple and convenient, and increases the stability of the cover plate. Attached Figure Description
