Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and particularly relates to a refrigerator body and a refrigerator in which a frequency conversion box is arranged on a rear panel of the refrigerator body. Background Art

[0002] As the world's demand for energy efficiency becomes increasingly higher, the home appliance industry has also ushered in new revolutionary changes, and there is an urgent need to improve the energy efficiency of the traditional home appliance industry.

[0003] There are three methods to improve the energy efficiency of existing refrigerators. The first is to change the foam material. The current unit thickness of foam material insulation technology has reached its limit. Under the premise of a significant increase in cost, the improvement in insulation performance is only a little, which is not worth the cost for ordinary household products. The second is to increase the thickness of the insulation layer. The thickness of the insulation layer of general household products is controlled at 55-65mm. Increasing the thickness of the insulation layer can improve the insulation performance, but too thick an insulation layer will increase the external size of the box or reduce the volume of the inner tank. On the other hand, increasing the insulation layer will greatly increase the weight of the box, making the box bulky and difficult to carry and move. At the same time, under the requirements of modern aesthetics, "thin skin and more fillings" is the future need; the third is the frequency conversion solution. Frequency conversion can effectively reduce the power of the compressor and improve the efficiency of electricity utilization. When the traditional foam insulation material of the refrigerator has not achieved qualitative changes, frequency conversion has a significant improvement in the improvement of the energy efficiency of the refrigerator.

[0004] However, it is difficult to carry out frequency conversion transformation for small refrigerators at present. The main reason is that the space of the compressor room of small refrigerators is too small to accommodate larger frequency conversion boards. Even if they can be placed in, the life of the electrical components on the frequency conversion board will be greatly reduced due to the temperature of the compressor room at high temperature, which is prone to failure. Utility Model Content

[0019] Figure 1 It is an exploded view of various components at the stretching hole on the rear panel of the utility model.

[0020] Figure 2 It is a structural diagram of the frequency converter box.

[0021] Figure 3 It is a structural diagram of the frequency conversion box cover. DETAILED DESCRIPTION

[0022] Example 1

[0023] A refrigerator box, such as Figure 1As shown, the top of the box is open, and the box includes a front panel, a rear panel 1, a left panel, a right panel and a bottom panel. A 2mm stretching hole 2 is provided in the middle and upper part of the rear panel 1, and the setting of the stretching hole 2 can increase the strength of the rear panel 1.

[0024] like Figure 1 and Figure 2 As shown, before foaming, a concave frequency conversion box 3 is pre-installed in the stretching hole 2, and the frequency conversion box 3 cooperates with the rear panel 1. The edges of the frequency conversion box 3 are all provided with a limiter 4 protruding inward for limiting. The height of the limiter 4 is about 1.5 mm, which can effectively limit the position and ensure the cooperation between the frequency conversion box 3 and the rear panel 1. The frequency conversion box 3 and the rear panel 1 are sealed with tape to ensure that the foaming agent cannot enter.

[0025] The frequency conversion box 3 is provided with a frequency conversion board, and the frequency conversion box cover 5 is provided at the opening of the outer side of the frequency conversion box 3. The material of the frequency conversion box cover 5 is metal, which can effectively protect the frequency conversion board. Figure 1 and Figure 3 As shown, the frequency conversion box cover 5 is connected to the rear panel 1 by screws, and there are three screw holes 6 on the frequency conversion box cover 5, and the three screw holes 6 are arranged in a triangle. In this embodiment, the three screw holes 6 on the frequency conversion box cover 5 are respectively located at the two ends of the long side of one side of the frequency conversion box cover 5 and in the middle of the long side of the other side of the frequency conversion box cover 5. The frequency conversion box cover 5 adopts a design of three screw holes 6, which can reduce the number of screws for fixing, ensures stability and reliability, and ensures production efficiency, thereby reducing production costs.

[0026] The frequency conversion box 3 penetrates into the foam layer by about 20 mm, and a VIP vacuum insulation panel 7 is adhered to the inner side of the frequency conversion box 3 to effectively reduce heat conduction and ensure that there is no condensation problem inside the frequency conversion box 3.

[0027] like Figure 2 As shown, the frequency conversion box 3 is provided with a plurality of threading holes 8 for wiring, which is conducive to separating the power line, the compressor line and the control board line, so as to separate the strong wire and the weak wire, and can successfully pass the EMC test.

[0028] Since the power line is directly connected to the inner side of the frequency conversion box 3, in order to solve the problem of grounding the power line, a grounding hole 9 is punched at the lower part of the rear panel 1. A flange 10 is provided at the edge of the grounding hole 9, and a screw hole is provided on the flange 10, through which the grounding hole 9 is screwed to the rear panel 1.

[0029] Example 2

[0030] A refrigerator, such as Figure 1As shown, the box comprises a box door 11 and the box body described in Example 1, wherein the box door 11 is connected to the rear panel 1 of the box body by a hinge. A hinge cover 12 is provided on the hinge. In order to ensure the packing size, the height of the frequency conversion box cover 5 does not exceed the height of the hinge cover 12.

[0031] The utility model installs the frequency conversion box 3 on the rear panel 1 of the box body, which is more convenient to install and maintain than installing it in the compressor room. The utility model can effectively perform frequency conversion transformation on old models of small refrigerators, effectively improving product competitiveness.

[0032] Parts not mentioned in the present invention can be realized by adopting or drawing on the prior art. It is worth noting that the solution of setting the frequency conversion box on the cabinet panel of the present invention is applicable to various refrigeration products with top-opening cabinet covers.
