Description

Technical Field

[0001] The utility model relates to a refrigerator. Background Art

[0002] In existing refrigerators, an evaporator including an accumulator is usually used. However, in such refrigerators, there are problems that the measured value of refrigerant noise is often high, and the impact noise of the refrigerant accumulated in the accumulator of the evaporator is too large during the shutdown and defrosting of the refrigerator, causing noise interference to the daily routine of users.

[0003] To solve the above problems, a structure in which a noise reduction layer is coated on the outer surface of the accumulator is usually adopted. However, such a noise reduction layer has problems such as secondary icing on its surface due to the refrigerant in the accumulator and requiring ice melting, easy aging, and low service life. Summary of the Utility Model

[0004] The utility model is the result of careful research in view of the above problems, and its purpose is to provide a refrigerator that can effectively reduce the refrigerant noise of the accumulator, effectively prevent icing and aging on the surface of the noise reduction layer coated on the outer surface of the accumulator, and reliably improve the service life of the noise reduction layer.

[0005] To achieve the above object, the refrigerator according to the utility model includes a box body and an evaporator disposed in the box body. The evaporator includes a pipe portion and an accumulator connected to the pipe portion. A noise reduction layer is coated on the outer surface of the accumulator, and a protective layer is further coated on the outer surface of the noise reduction layer.

[0006] That is, the utility model first coats the noise reduction layer on the accumulator of the evaporator, and effectively reduces the refrigerant ejection noise of the accumulator through the shock absorption and sound absorption effect of the noise reduction layer, greatly improving the actual listening experience and enhancing the actual experience of users. Thus, the refrigerant noise of the accumulator can be effectively reduced. Further, the utility model coats the protective layer on the outer surface of the noise reduction layer, so that by using the protective layer, the refrigerant noise of the accumulator can be further effectively reduced, the surface icing and aging of the noise reduction layer coated on the outer surface of the accumulator can be effectively prevented, and the service life of the noise reduction layer can be reliably improved.

[0007] In addition, in the refrigerator according to the above utility model, the thickness of the noise reduction layer may be 1 mm to 5 mm. In this way, by setting the thickness of the noise reduction layer within the range of 1 mm to 5 mm, the refrigerant noise of the accumulator can be more effectively reduced.

[0008] In addition, in the refrigerator according to the above-mentioned present utility model, the thickness of the protective layer may also be 0.1 mm to 0.5 mm. By setting the thickness of the protective layer within the range of 0.1 mm to 0.5 mm, the refrigerant noise of the accumulator can be more effectively reduced, the surface icing and aging of the noise reduction layer coated on the outer surface of the accumulator can be more effectively prevented, and the service life of the noise reduction layer can be more reliably improved.

[0009] In addition, in the refrigerator according to the above-mentioned present utility model, the protective layer may be composed of a metal foil, and preferably the protective layer is composed of an aluminum foil. In this way, by coating a metal foil such as an aluminum foil outside the noise reduction layer, the sound absorption effect is further improved, the service life of the constituent material (for example, butyl rubber) of the noise reduction layer is increased, and the defrosting performance around the evaporator is enhanced. Specifically, the smooth surface of the metal foil such as an aluminum foil can quickly drain the defrosting water droplets, prevent the water droplets from staying and icing, so that the problem of secondary icing due to the refrigerant in the accumulator on its surface and the need for ice melting can be effectively solved. In addition, the metal foil such as an aluminum foil has the functions of anti-aging and waterproofing, increasing the service life of the constituent material (for example, butyl rubber) of the noise reduction layer. In addition, the metal foil such as an aluminum foil also has a heat insulation function, which can inhibit the deformation of the constituent material (for example, butyl rubber) of the noise reduction layer caused by the temperature rise during defrosting. In addition, the surface of the metal foil such as an aluminum foil can reflect heat, improving the defrosting performance around the evaporator. Furthermore, the metal foil such as an aluminum foil also has a certain sound absorption function, and when used in combination with, for example, rubber, the sound reduction effect is better.

[0010] In addition, in the refrigerator according to the above-mentioned present utility model, the noise reduction layer may be composed of butyl rubber. In this way, since the damping and sound absorption effect of butyl rubber is better, the refrigerant noise of the accumulator can be more effectively reduced.

[0011] In addition, in the refrigerator according to the above-mentioned present utility model, the evaporator may be arranged on the back side of the cabinet.

[0012] In addition, in the refrigerator according to the above-mentioned present utility model, the evaporator may be arranged in the refrigerating chamber of the refrigerator.

[0013] In addition, in the refrigerator according to the above-mentioned present utility model, the evaporator may be arranged in the freezing chamber of the refrigerator.

[0014] According to the present utility model, a refrigerator can be provided which can effectively reduce the refrigerant noise of the accumulator, effectively prevent the surface icing and aging of the noise reduction layer coated on the outer surface of the accumulator, and reliably improve the service life of the noise reduction layer.

As Figure 2 shown, a noise reduction layer 201 is coated on the outer surface of the accumulator 20, and a protective layer 202 is further coated on the outer surface of the noise reduction layer 201.

[0026] That is, in this embodiment, the noise reduction layer is first coated on the accumulator of the evaporator, and the refrigerant ejection noise of the accumulator is effectively reduced through the shock absorption and sound absorption effect of the noise reduction layer, greatly improving the actual listening experience and enhancing the actual experience of users. Thus, the refrigerant noise of the accumulator can be effectively reduced. Further, in the present utility model, the protective layer is coated on the outer surface of the noise reduction layer, so that the protective layer can further effectively reduce the refrigerant noise of the accumulator, can effectively prevent the surface of the noise reduction layer coated on the outer surface of the accumulator from icing and aging, and can reliably improve the service life of the noise reduction layer.

[0027] In addition, in this embodiment, the thickness of the noise reduction layer 201 is preferably 1 mm to 5 mm, and more preferably 2 mm to 3 mm. In this way, by setting the thickness of the noise reduction layer within the range of 1 mm to 5 mm, the refrigerant noise of the accumulator can be more effectively reduced.

[0028] In addition, in this embodiment, the noise reduction layer 201 is preferably made of butyl rubber. In this way, due to the better shock absorption and sound absorption effect of butyl rubber, the refrigerant noise of the accumulator can be more effectively reduced.

[0029] In addition, in this embodiment, the protective layer 202 is preferably made of metal foil, and more preferably made of aluminum foil. In this way, by coating a metal foil such as aluminum foil on the outside of the noise reduction layer, the sound absorption effect is further improved, the service life of the constituent material (for example, butyl rubber) of the noise reduction layer is increased, and the defrosting performance around the evaporator is enhanced. Specifically, the smooth surface of the metal foil such as aluminum foil can quickly drain the defrosting water droplets, prevent the water droplets from staying and icing, so that the problem of secondary icing due to the refrigerant in the accumulator on its surface and the need to melt the ice can be effectively solved. In addition, the metal foil such as aluminum foil has the functions of anti-aging and waterproofing, increasing the service life of the constituent material (for example, butyl rubber) of the noise reduction layer. In addition, the metal foil such as aluminum foil also has a heat insulation function, which can inhibit the deformation of the constituent material (for example, butyl rubber) of the noise reduction layer caused by the temperature rise during defrosting. In addition, the surface of the metal foil such as aluminum foil can reflect heat, improving the defrosting performance around the evaporator. Furthermore, the metal foil such as aluminum foil also has a certain sound absorption function, and when used in combination with, for example, rubber, the sound reduction effect is better.

[0030] In addition, in this modification example, the thickness of the protective layer 202 is preferably 0.1 mm to 0.5 mm, and more preferably 0.15 mm to 0.25 mm.
