Referring to these drawings, a conventional refrigerator includes a freezer compartment 1 for producing ice inside a door 3, a refrigerator compartment 2 for storing food for a long time in a low temperature state, and a vegetable compartment 4 for freshly storing vegetables and the like. The beverage is stored in the beverage container provided in the inner wall of the door (3).

The refrigerator having such a structure exerts its performance by cold air generated by a compression refrigeration cycle. In more detail, the refrigerator 9 converts a low temperature low pressure gas refrigerant into a high temperature high pressure gas refrigerant, and the high temperature high pressure gas refrigerant. The condenser 5 is converted into a liquid refrigerant of medium temperature and high pressure, an expansion valve 7 in which the medium temperature and high pressure liquid refrigerant is converted into a low temperature low pressure liquid refrigerant, and the low temperature low pressure liquid refrigerant is converted into a low temperature low pressure gas refrigerant. The refrigeration cycle is completed by the evaporator (8).

With reference to FIG. 3, elements of some of the engines that complete the compression refrigeration cycle are located in the machine room located at the bottom of the refrigerator, such as the condenser 5, the compressor 9, the cooling fan 6, and the like. In order to discharge the hot air from the machine room to the outside, the refrigerator is usually spaced apart from the wall by a certain distance, which is necessary for the refrigerator to be able to perform its function only when it releases a sufficient amount of hot air from the machine room to the outside. Because.

On the other hand, in the process of performing the compression refrigeration cycle, foreign matter such as dust is introduced together with the outside air through the cover inlet of the machine room is stacked or attached to the parts inside the machine room.

Therefore, when a refrigerator is used for a long time, when foreign matter such as dust adheres to the refrigerant pipe and the cooling fin of the condenser 5, the heat exchange performance is greatly deteriorated, and the compressor is overloaded, resulting in increased power consumption. Etc. problems will occur.

The present invention has been made in view of the above problems, in the refrigerator or air conditioner, such as to prevent the adhesion of dust and foreign matter to the refrigerant pipe and the cooling fin of the condenser and to prevent overload of the compressor, thereby maintaining heat exchange performance, The purpose is to enable low power consumption.

The new type of photocatalyst coating for preventing dust adhesion according to the present invention for achieving the above object is a condenser in a machine room consisting of a compressor, a condenser, a cooling fan, and the like, wherein the condenser is attached to a refrigerant pipe and the refrigerant pipe. Photocatalyst coating on the surface of the, characterized in that it further comprises an ultraviolet lamp in the vicinity of the condenser.

Hereinafter, a preferred embodiment of the photocatalyst coating new type condenser for preventing dust adhesion according to the present invention will be described with reference to the accompanying drawings.

Photocatalyst coating for preventing dust adhesion according to the present invention is characterized in that the photocatalyst coating on the surface of the refrigerant pipe and the cooling fins attached to the refrigerant pipe. In general, the principle of the photocatalytic reaction is represented by ZnO. , Cds, WO3, TiO2, among which photocatalyst titanium dioxide (TiO2) is activated by ultraviolet energy emitted from the sun or fluorescent lamps to generate active oxygen from oxygen or water in the air.

The oxidizing power of the active oxygen decomposes all organic substances that cause odors or dirts attached to the surface of the photocatalyst, and according to this reaction, it removes odors, sterilizes bacteria, antibacterial, prevents pollution, air purification, and water purification. Have In other words, due to the oxidative decomposition action and hydrophilic activity of the photocatalyst titanium dioxide, dirts such as odors and dusts are less likely to stick to each other, and once attached, the dirts are likely to fall off, thereby exhibiting an antifouling effect.

The new type of photocatalyst coating for preventing dust adhesion according to the present invention is characterized by further comprising an ultraviolet lamp 11 in the vicinity of the condenser 5a, which is installed under the ultraviolet lamp 11 as shown in FIG. Ultraviolet light having a wavelength of 380 nm or less is irradiated to the phase condenser 5a, and the photocatalyst is excited.

Therefore, the dust and foreign substances introduced through the machine room cover suction port by the blower fan 6 are hard to adhere to the refrigerant pipe and the cooling fin of the condenser 5a, and once the contaminants are easily removed, the effect of suppressing the heat exchange performance of the condenser is suppressed. Will be

In this case, it is preferable to include the reflector 11a around the ultraviolet lamp 11 so that the photocatalytic action as described above is more efficient. Looking at this in more detail, the reflector installed around the ultraviolet lamp 11 ( The ultraviolet light emitted from the ultraviolet lamp 11 by 11a is uniformly transmitted to the condenser 5a, and thus the photocatalytic action is more active in the condenser 5a that is sufficiently irradiated with ultraviolet light.
