Description

Air Purifying Device for Air Conditioner

The present invention relates to an air purifying apparatus using an ultraviolet lamp and a photocatalyst. In particular, the surface area of a target portion to which ultraviolet rays are irradiated can be increased to maximize a photocatalytic effect and provide a comfortable indoor environment. The present invention relates to an air conditioner for an air conditioner that protects a lamp, simplifies the electrical wiring of the air conditioner outer wall, eliminates the inconvenience of puncturing the outer wall of the air conditioner, and prevents leakage of air through the gap.

Generally, sterilizing ultraviolet light has been widely used as a method for sterilizing microorganisms, viruses and bacteria in the medical industry for several decades, and also has been used for air purification devices due to the ultraviolet light sterilizing effect. .

In addition, since ultraviolet rays are not effective for removing gaseous contaminants or odors, gaseous pollutants and odors are caused by oxidation reaction of titanium oxide by attaching a titanium oxide coated target portion around the ultraviolet lamp. Is removing.

In addition, as described above, the target portion coated with titanium oxide has a clogging phenomenon due to adsorption of dust, and thus, the filter must be periodically replaced and the gaseous contaminants and odors cannot be effectively removed. Applicant has developed an air purification module coated with not only titanium oxide, but also silver oxide, copper oxide and rhodium oxide, and registered it as patent No. 592872.

As such, the air purification module provided with the target portion coated with titanium oxide, silver oxide, copper oxide, and rhodium oxide provides an air purification, sterilization, and deodorization device that can effectively remove gaseous contaminants or odors.

However, as shown in Figure 1, the conventional air purification module (C) has a structure that is installed by puncturing the outer wall of the air conditioner (90) or puncturing the air supply doc, the following various problems occur It was.

The conventional air purification module (C) fixes the ultraviolet lamp (1), the target portion (2) installed around the ultraviolet lamp (1), the ultraviolet lamp (1) and the target portion (2) and the power supply It consists of a fixed part 5 to supply. The target unit 2 is a catalyst network on which various catalysts are coated, which causes an oxidation reaction when ultraviolet rays are irradiated to generate various air purification gases.

On the other hand, the air conditioner 90 is formed in a substantially rectangular parallelepiped shape, the suction chamber 91 in which a ventilation fan for drawing air in the room is installed, the mixing chamber 92 in which the sucked air is mixed, and in the air. Filtration chamber 93 for removing mixed dust and the like, coil box 94 for cooling or warming air, air purification chamber 95 for purifying gaseous contaminants and odors contained in air, and harmonized It is comprised by the air supply chamber 96 provided with the air supply fan which supplies air indoors.

The above-described air purification module C forms a through hole 97 on the outer wall of the air purification chamber 95 and through the through hole 97 the ultraviolet lamp 1 and the target portion inside the air purification chamber 95. Insert (2).

Such a conventional air purifying module installation structure must puncture the through hole 97 through the outer wall of the air purification chamber 95, whereby air is leaked through the gap of the through hole 97, and the air conditioner Since the ultraviolet lamp 1 and the target portion 2 are embedded in the outer wall (thickness of about 50mm) by the thickness, the photocatalytic action occurs less.

Since the fixing part 5 of the air purifying module C protrudes outside of the air conditioner, it is easy to be damaged due to an impact, and since the wires must be connected to the fixing part 5, the wires are dizzy from the outside of the air conditioner. Wiring, especially when a plurality of air purification module (C) is installed because they are connected in parallel, there was a problem that the wiring of the wire is more disturbing.

Therefore, the present invention is proposed to solve the problems of the conventional air conditioner and air purification module, to maximize the surface area of the target portion irradiated with ultraviolet rays to maximize the photocatalytic action, and installed in the air conditioner to improve safety An object of the present invention is to provide an air conditioner for an air conditioner that eliminates the clutter caused by wires wired to the outside of the air conditioner.
