Description

Air filter for air conditioner {air filter for the airconditioner}

The present invention relates to an air purifier for an air conditioner, and more particularly, to an air purifier for an air conditioner for purifying circulating air flowing into the air conditioner.

In general, an air conditioner has a function of converting indoor hot air into relatively cold air during a hot summer with a relatively high temperature, and simultaneously discharging the heat exchanged hot air to the outside. In recent years, as income levels have risen, the demand for each family soared, often preparing for a cool summer.

As shown in FIG. 1, the air conditioner includes a main body 3 having an inlet 1 for sucking hot air at a lower part thereof, an outlet 2 provided at the upper part for discharging cold air converted from hot air, and It is installed in the receiving space of the main body 3 has a cooling coil for heat exchange (not shown) for converting into cold air through a predetermined heat exchange process. The cooling coil is connected to a compressor for circulating a refrigerant, a receiver for removing moisture from the refrigerant, and a capillary tube for rapidly reducing the temperature change of the refrigerant. Inside the suction port, a filter for purifying the air in the room is mounted. Here, the filter is made of a non-woven fabric that filters out only a relatively large foreign material, that is, a large amount of dust, or by laminating the non-woven fabric in a double so that foreign matters do not stick to the cooling coil.

However, when the air conditioner is operated, the air is circulated by closing the space in order to prevent cold air from leaking out. The filter, that is, the nonwoven fabric, may cause food smell, cigarette smell, and indoor dust caused by people entering the room. And because it can not filter various harmful gases, there is a problem that can not protect the health of other people by the various pathogens and dirty air such as viruses and ticks.

In addition, since the condensation water accumulates in the drain plate at the bottom of the air conditioner, it provides a breeding ground for various bacteria, which causes a source of harmful environment. There is a problem that odor occurs due to corruption.

The present invention was devised to solve the above problems, and cleans and cleans the air by cleaning and sterilizing pollen and various foreign substances contained in the circulating air of the air conditioner, ie harmful gases, pathogens, viruses and smells of cigarettes and cigarettes. To provide an air purifier for an air conditioner, the purpose is.

The above object is, according to the present invention, in the air purifier for an air conditioner having a main body in which the inlet and the outlet are formed separately, and a cooling coil for heat exchange at a relatively low temperature in the inlet, wherein the inlet is provided with a relatively large amount of A pre-treatment filter for removing foreign substances, a photocatalyst filter for decomposing at least one of viruses, bacteria, pathogens and a plurality of odors and harmful gases from air passing through the pre-treatment filter to remove harmful substances, and an area adjacent to the photocatalyst filter It is achieved by an air conditioner for an air conditioner comprising an ultraviolet lamp disposed in the ultraviolet light.

Here, the photocatalyst filter has a mesh of a relatively small size, and the mesh is preferably coated with titanium oxide, which chemically reacts with the ultraviolet rays.

In addition, the ultraviolet lamp is preferably operated in the same manner as the operation of the blowing fan for air circulation.

In addition, it is preferable that an ion precipitator is installed between the photocatalyst filter and the pretreatment filter to increase the adsorption rate of at least one of viruses, bacteria, pathogens and a plurality of odors and noxious gases from the circulating air with a charge amount.

Hereinafter, with reference to the accompanying drawings will be described in detail an air purifier for an air conditioner according to the present invention. 2 is a cross-sectional view showing the air purifying apparatus of the present invention, Figure 3 is a view illustrating the air filter function of the present invention, Figure 4 is a flow chart showing the air inlet path of the present invention.

2 and 3, the air purifier is provided with a cooling system (not shown) and an air inlet for providing an air conditioning passage (or air passage) for exchanging indoor air with relatively cold air through the cooling system. A pretreatment filter 15 provided with a main body 13 having an outlet 11 and a suction port 11 located below the main body 13 to filter foreign substances of relatively large particles in the room; And a cooling coil 17 installed so as to stand in the suction port 11 to expand the contact area with the air in the room according to the circulation of the refrigerant from the cooling system, and to heat-exchange with cold air, and to the bottom of the cooling coil 17. The drain vessel 19 is provided on the surface and receives the condensation water generated during operation of the refrigeration system, and installed in the air conditioning passage between the cooling coil 17 and the pretreatment filter 15 A photocatalyst filter 20 which removes and deodorizes at least one of viruses, bacteria, pathogens and a plurality of odors and harmful gases from the air, and the virus, bacteria, pathogens and a plurality of odors and harmful substances in the photocatalyst filter 20. At least one of the gases has an ultraviolet lamp 23 that causes a specific chemical reaction to change from a hazardous substance to a harmless substance.

Here, the drain vessel 19 is installed to receive the water generated by the photocatalyst filter 20, the ultraviolet lamp 23 is used to receive the power of the blowing fan (not shown) of the cooling system. Therefore, it operates in the same manner as the blowing fan, is installed in one position to be irradiated to the photocatalyst filter 20, and generates a strong ultraviolet in the inverter type. And, between the photocatalyst filter 20 and the pretreatment filter 15, an ion precipitator for increasing the adsorption rate so as to adsorb at least one of viruses, bacteria, pathogens and a plurality of odor grains and harmful gases with an electric charge amount ( 25) may be installed. Here, the ion precipitator 25 charges a negative charge to the dust collecting plate to strongly adsorb various foreign matters having a positive charge, and is installed in close proximity to the photocatalyst filter 20 so that a greater amount of virus, bacteria, pathogens and Induces the removal of numerous odor grains and harmful gases.

On the other hand, the class removed by the photocatalyst filter 20 and the ultraviolet lamp 23 is a building material odor generated in new buildings and exhaust gases (NO _X ) harmful to the human body, tobacco smell, pet smell, food smell, Pathogenic bacteria and bacteria (viruses). That is, the building material odor is formaldehyde, the main component is decomposed into carbon dioxide gas and water by a strong oxidation reaction, the exhaust gas is a nitrogen oxide, so the harmful gas is decomposed and removed by a strong chemical reaction, the tobacco smell is Since the main ingredients are formaldehyde, ammonia and acetaldehyde, they are decomposed by strong oxidation, and the pet animal smell is decomposed and removed by carbon dioxide and water by strong oxidation because its main ingredients are ammonia, hydrogen sulfide and methyl mercaptin. Since the main components are ammonia and hydrogen emulsion, they are removed by oxidation, and finally, bacteria and viruses destroy and inactivate cell membranes to stop their activity.

As shown in FIG. 4, the air conditioning path of the air purifying apparatus as described above is circulated through the inlet port 11 and the outlet port by a blower fan (not shown) of the cooling system. More than% air is sucked through the inlet 11 (S1). The air sucked in this way is filtered through a pretreatment filter 15 fixed to the back of the inlet, that is, relatively large dust, ie, foreign particles (S3), and the filtered air passes through the photocatalyst filter 20 to the ultraviolet lamp 23. By removing the harmful substances such as building materials smell, exhaust gas (NO _X ), tobacco smell, pet smell, food smell, pathogenic bacteria and bacteria (viruses) are removed by changing to harmless substances that do not affect the human body (S5, S7). At this time, most of the harmful substances are decomposed into hydrogen peroxide and hydroxyl radical (OH).

The fresh air thus removed flows along the flow path toward the refrigerant coil 17 (S9). Then, the fresh air is heat-exchanged and converted into cold air, and the air is circulated because it exits to the outlet through the blowing fan (S11 and S13). When the primary circulating air is re-introduced, only 10% of the circulated air is introduced into the recirculation, and the remaining 90% of the contaminated air remaining in the room is recirculated through the above path (S15).

On the other hand, when the ion precipitator 25 is installed, the air purified by the pretreatment filter 15 is once again purified by the ion precipitator 25, the building material smell, exhaust gas and tobacco smell, pet smell and food smell At least one of bacteria and viruses is adsorbed to the dust collecting plate with negative ions to remove foreign substances of the cation.

The present invention cleans and cleans air by cleaning and disinfecting pollen and various foreign substances, such as harmful gases, pathogens, viruses and cigarette smells, contained in the circulating air of an air conditioner. By purifying with clean clean air, it can keep user's health all the time, and it has the effect of creating a pleasant environment by blocking harmful environment at all times.
