Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a refrigerator with an anti-condensation function. Background Art

[0002] Commercial refrigerators are refrigeration equipment used for commercial purposes, mainly used in supermarkets, convenience stores, restaurants, bars and other places to store food and other goods that need to be kept at low temperatures.

[0003] Existing commercial refrigerators lack anti-condensation measures on the cabinet body. Due to the temperature difference between the inside and outside of the refrigerator, condensation will occur on the surface of the cabinet body near the door, causing dew to adhere to the cabinet surface for a long time, so that the surface of the cabinet body near the door is always in a humid environment. On the one hand, it will aggravate the corrosion of the metal parts on the cabinet body; on the other hand, the dew condensed on the surface of the cabinet body near the door end can easily drip onto the ground where the refrigerator is located, causing water to accumulate on the ground, which can easily cause people to slip. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies in the prior art and provide a refrigerator with an anti-condensation function.

At the same time, it also avoids the problem of water accumulation on the ground caused by dew condensed on the cabinet body surface dripping onto the ground where the refrigerator is located.

The insulating heat-conducting layer can conduct the heat of the heating wire to the cabinet body and heat the cabinet body, while ensuring the insulation between the heating wire and the cabinet body, thereby preventing the cabinet body from being electrified and ensuring the safe use of the refrigerator. The pressing piece applies a pressing force to the heating wire in the direction of the cabinet door, and the pressing piece enables the heating wire to be in close contact with the insulating heat-conducting layer, so that the heat of the heating wire can be fully conducted to the surface of the cabinet body.

[0007] Preferably, the insulating heat-conducting layer is made of thermally conductive silicone.

[0021] The following will be combined with the drawings in 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, a refrigerator with an anti-condensation function includes a cabinet body 1 and a cabinet door 2. A heating wire 4 is provided on the inner side of the cabinet body 1 near the cabinet door 2, and the heating wire 4 is connected to a heating controller; an insulating heat-conducting layer 5 is provided between the heating wire 4 and the cabinet body 1; a pressing piece is provided on the inner side of the cabinet body 1 near the cabinet door 2, and the pressing piece applies a pressing force on the heating wire 4 toward the cabinet door 2.

[0023] In the present invention, a heating wire 4 is provided on the inner side of the cabinet body 1 near one end of the cabinet door 2. The heating wire 4 can heat one end of the cabinet body 1, thereby preventing condensation from forming on the surface of the cabinet body 1, thereby keeping the surface of the cabinet body 1 dry and avoiding corrosion of the metal components on the cabinet body 1. It also avoids the problem of water accumulation on the ground where the refrigerator is located due to dew condensing on the surface of the cabinet body 1 dripping onto the ground. An insulating thermally conductive layer 5 is provided between the heating wire 4 and the cabinet body 1. The insulating thermally conductive layer 5 can transfer the heat of the heating wire 4 to the cabinet body 1 and heat the cabinet 1, while ensuring the insulation between the heating wire 4 and the cabinet body 1, thereby preventing the cabinet 1 from being charged and ensuring the safe use of the refrigerator. A pressing member applies a pressing force to the heating wire 4 toward the cabinet door 2, which allows the heating wire 4 to be in close contact with the insulating thermally conductive layer 5, so that the heat of the heating wire 4 can be fully transferred to the surface of the cabinet body 1.

[0024] In this embodiment, the insulating heat-conducting layer 5 is made of heat-conducting silicone.

[0025] The cabinet 1 includes two side panels 1-1. A bottom panel 1-2, a support beam 1-4, and a top panel 1-3 are arranged in order from the lower right side panel 1-1 upward. Each of the side panels 1-1, the top panel 1-3, the support beam 1-4, and the top panel 1-3 is hollow. In this embodiment, the side panels 1-1, the top panel 1-3, the support beam 1-4, and the top panel 1-3 are all sheet metal structures, formed by bending metal sheets.

[0026] A heating wire opening 1-5 is provided on the top plate 1-3, and both ends of the heating wire 4 pass through the heating wire opening 1-5 and are connected to a heating controller.

[0027] Specifically, the pressing part includes a bracket 6 and a thermal bending plate 7. The middle part of the thermal bending plate 7 is fixedly connected to the bracket 6. The thermal bending plate 7 is composed of a first metal layer 7-1 and a second metal layer 7-2. The first metal layer 7-1 is arranged on the side of the second metal layer 7-2 away from the cabinet door 2. The thermal expansion coefficient of the first metal layer 7-1 is greater than the thermal expansion coefficient of the second metal layer 7-2; the heating wire 4 is sandwiched between the thermal bending plate 7 and the insulating layer 8.

[0028] Among them, two heating wires 4 pass through the side plate 1-1, the top plate 1-3, the supporting beam 1-4 and the top plate 1-3 (as shown in FIG. Figure 6 As shown in FIG5 , two heating wires 4 are located at the two ends of the thermal bending sheet 7. The thermal bending sheet 7 itself has a certain elasticity, and the elastic force of the thermal bending sheet 7 can keep the heating wire 4 in close contact with the insulating heat-conducting layer 5. Moreover, when the heating wire 4 is working, the heating wire 4 rises steadily, thereby increasing the temperature of the thermal bending sheet 7. Since the thermal expansion coefficient of the first metal layer 7-1 on the thermal bending sheet 7 is greater than the thermal expansion coefficient of the second metal layer 7-2, the two ends of the thermal bending sheet 7 will bend toward the heating wire 4, thereby increasing the pressing force of the heating wire 4, fully ensuring that the heating wire 4 can fully contact with the insulating heat-conducting layer 5 during operation, and ensuring the effectiveness of heat transfer between the heating wire 4 and the cabinet 1.

[0029] The bracket 6 is T-shaped and is fixed to the cabinet 1 by welding.

[0030] An insulating layer 8 is provided on the side of the heat bending sheet 7 close to the heating wire 4. By arranging the insulating layer 8 on the heat bending sheet 7, the insulation between the heating wire 4 and the heat bending sheet 7 is guaranteed to ensure that the cabinet 1 will not be charged.

[0031] A control panel 3 is located at the top of the cabinet 1. The heating controller controls the operation of the heating wire 4. The heating controller can be manually controlled by pressing a button. Alternatively, the heating wire 4 can be controlled by setting an operating mode, including time-proportioned on / off control, synchronized operation with the refrigerator's compressor, and continuous operation.

[0032] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
