The air conditioner shown in Fig. 7 includes all the various members described in Figs. 1 to 4 in addition to the front panel 710, the chassis 720, the wind direction adjusting member 730, the fan 740, and the heat exchanger 750 . 7, only the front panel 710, the chassis 720, the wind direction adjusting member 730, the fan 740, the heat exchanger 750, and the ultraviolet sterilizing module 760 will be described.

The main body 700 may have an air inlet 712 formed on the upper surface of the air conditioner and an air outlet 714 formed on the lower surface of the air conditioner. The main body 700 is formed such that the air inlet 712 is formed on the upper surface of the air conditioner and the air outlet 714 is formed on the lower surface of the air conditioner and the front panel 710 covers the front surface of the air conditioner. .

The main body 700 may be formed such that the air inlet 712 is formed on the upper portion of the air conditioner, particularly on the upper surface side of the air conditioner, and the air outlet 714 is formed on the lower portion of the air conditioner, . Further, the front panel 710 forms a front-side outer tube of the air conditioner, and is rotated so as to protrude frontward about the upper portion for service inside the air conditioner.

The structure and function of the front panel 710, the chassis 720, the wind direction adjusting member 730, the fan 740, and the heat exchanger 750 in the main body 700 according to the embodiment of the present invention are shown in FIG. 1 4, except for the redundant description.

The ultraviolet sterilizing module 760 included in the air conditioner according to an embodiment of the present invention may be disposed before the heat exchanger 750 in the air flow direction. The ultraviolet sterilization module 760 may be located in the air intake passage between the front panel 710 and the heat exchanger 750.

The porous main body 762 may be formed in a structure through which air can pass, and the porous main body 762 may be formed with a plurality of holes 766 through which air passes. The porous main body 762 may be formed of a porous plate having a plurality of holes 766, and may be formed of a wire assembly in which a plurality of wires are cross-connected. When the porous main body 762 is composed of a wire combination, a hole 766 through which air can pass may be formed between a plurality of wires. Hereinafter, the porous main body 762 may be referred to as a mesh, a web, a main body, a body, a supporting body, a porous lamp supporting body, a web main body, a mesh body,

The porous main body 762 may be provided with a hole 766 through which the air flows toward the ultraviolet lamp 764. These holes 766 may be formed with holes 766 of a predetermined size or more to minimize the flow path resistance by the porous main body 762. The porous main body 762 can be made of an elastic material and has a rounded curved surface or a shape bent at least once so as to correspond to the shape of the heat exchanger 750 and has a body 700 and a heat exchanger 750). ≪ / RTI >

Preferably, the ultraviolet sterilization module 760 is capable of emitting heat in the ultraviolet lamp 764, and the porous main body 762 is formed of a heat-resistant material. In addition, the porous main body 762 is preferably formed of a metal material rather than a synthetic resin material such as plastic. The porous main body 762 is preferably formed of a material having good durability against heat and moisture, and may be formed of aluminum (Al). Here, the aluminum (Al) material may include an aluminum material and an aluminum alloy material.

The porous main body 762 may be positioned before the ultraviolet lamp 764 and the heat exchanger 750 in the direction of air flow. When the photocatalyst material is applied to the surface of the porous main body 762, the air may be deodorized by the porous main body 762 and then flowed to the ultraviolet lamp 764 and the heat exchanger 750. That is, when the photocatalyst material is applied to the surface of the porous main body 762, the deodorizing component in the air can be minimally adsorbed on the surface of the ultraviolet lamp 764. Degradation of the performance of the ultraviolet lamp 764 which may be generated when the deodorizing component is excessively adsorbed on the surface of the ultraviolet lamp 764 can be minimized.

Examples of the photocatalyst material formed on the surface of the porous main body 762 include titanium oxide (TiO2), zinc oxide (ZnO), cadmium sulfide (CdS), zirconia (ZrO2), vanadium oxide (V2O3) WO3), and the like. The air sucked into the air inlet 712 is primarily deodorized by the porous main body 762 and can be sterilized by the ultraviolet lamp 764. The deodorized and sterilized air is introduced into the heat exchanger 750 Can be inhaled.

On the other hand, the porous main body 762 can minimize the interference with the flow of the gas even if it is disposed in the space where the gas flows. Further, in the course of the gas passing through the porous main body 762, by flowing close to the ultraviolet lamp 764, the intensity of the ultraviolet rays transmitted to the gas or the range of irradiation of ultraviolet rays can be increased. Accordingly, the sterilizing power of the ultraviolet sterilization module 760 can be increased.

The ultraviolet sterilization module 760 may include a plurality of ultraviolet lamps 764 and the plurality of ultraviolet lamps 764 may be spaced apart from each other in the porous main body 762. The plurality of ultraviolet lamps 764 may be disposed at least partially in parallel. The plurality of ultraviolet lamps 764 may be all arranged in parallel. A plurality of ultraviolet lamps 764 may be disposed in the porous main body 762 at predetermined intervals. The plurality of ultraviolet lamps 764 may be arranged in parallel.

The plurality of ultraviolet lamps 764 may be disposed apart from both sides of the porous main body 762. A plurality of ultraviolet lamps 764 can be positioned entirely in the air flow direction between the porous main body 762 and the heat exchanger 750. It is also possible that a portion is located between the porous main body 762 and the heat exchanger 750 and the rest is disposed between the porous main body 762 and the front panel 710. The ultraviolet lamp 764 disposed between the porous main body 762 and the front panel 710 can primarily sterilize air passing between the air inlet 712 and the porous main body 762. [ The ultraviolet lamp disposed between the porous main body 762 and the heat exchanger 750 can sterilize the air having passed through the porous main body 762.

As described above, the ultraviolet lamp is dispersed in the porous main body 762, and the porous main body 762 can be coated with the photocatalyst material. As a result, the air can be primarily sterilized between the air inlet 712 and the porous main body 762. Further, when deodorized by the porous main body 762, it can be sterilized secondarily between the porous main body 762 and the heat exchanger 750.

The ultraviolet sterilization module 760 may include a holder (not shown) for supporting the ultraviolet lamp 764. The holder may support the ultraviolet lamp 764 such that the ultraviolet lamp 764 is spaced apart from the porous main body 762. The holder can support a plurality of ultraviolet lamps (764), and a pair of holders can support ultraviolet lamps (764). The ultraviolet sterilization module 760 may include a plurality of pairs of holders. The plurality of pairs of holders may be arranged at regular intervals of the porous main body 762. [ The ultraviolet sterilization module 760 according to an embodiment of the present invention may include a plurality of ultraviolet lamps 764, a power supply unit (not shown), and wires (not shown).

The ultraviolet lamp 764 may be provided by an external electrode method having an external electrode. Thus, a first electrode may be provided on one side of the ultraviolet lamp 764, and a second electrode may be provided on the other side. The first electrode and the second electrode may be provided by applying a conductive solder liquid to the outside of the ultraviolet lamp 764. Also, the first electrode and the second electrode may be provided by applying a silver paste. The first electrode and the second electrode may be provided by applying carbon nanotube (CNT) and curing the carbon nanotube. That is, the ultraviolet lamp 764 and the first electrode and the second electrode are separately provided, and an electric field may be formed between the first electrode and the second electrode. The radiation material in the ultraviolet lamp 764 is induced by the electric field to generate ultraviolet rays. Since the first electrode and the second electrode are not in contact with the material enclosed in the ultraviolet lamp 764, the heat that may be generated in the ultraviolet lamp 764 is reduced, so that the life of the ultraviolet lamp 764 Can be increased.

The power supply unit may supply power to the ultraviolet lamp 764. The power supply unit can stabilize the current supplied to the ultraviolet lamp 764. [ Further, the power supply unit can generate a high voltage required for generating ultraviolet rays in the ultraviolet lamp 764. [ That is, the power supply unit may be provided with the output frequency and the driving voltage changed in accordance with the driving frequency and the driving voltage for driving the plurality of ultraviolet lamps 764. For example, the power supply may be provided as an inverter, a ballast, or the like.

The electric wire can connect a power supply unit and a plurality of ultraviolet lamps 764. In detail, the electric wire may connect the first electrode and the second electrode to the power supply unit. The electric wires can connect the plurality of ultraviolet lamps 764 and the power supply unit in parallel. That is, a plurality of ultraviolet lamps 764 can be operated simultaneously by connecting a power supply unit and a plurality of ultraviolet lamps 764 in parallel. Even when one ultraviolet lamp 764 of the plurality of ultraviolet lamps 764 is defective, maintenance is easy.

Meanwhile, the ultraviolet lamp 764 according to an embodiment of the present invention is described as an external electrode fluorescent lamp in which an electrode is provided on the outside, but a method in which the electrode is disposed inside the ultraviolet lamp is also possible.

Hereinafter, the configuration of the ultraviolet lamp 764 will be described in detail. The external electrode fluorescent lamp type ultraviolet lamp 764 may be formed in the form of a bar or a tube in which an internal space is formed. The ultraviolet lamp 764 may be formed to be shielded so as to have a sealed inner space. The ultraviolet lamp 764 may be formed of one of quartz, borosilicate, glass containing quartz or borosilicate. In addition, a radiation material capable of generating the ultraviolet rays may be enclosed in an inner space of the ultraviolet lamp 764. The radiation material may be discharged by the first electrode and the second electrode disposed on both sides of the ultraviolet lamp 764 to generate ultraviolet rays.

For example, mercury (Hg), neon (Ne), xenon (Xe), krypton (Kr), argon (Ar), xenon bromide (XeBr) At least one of brominated krypton (KrBr), krypton chloride (KrCl), and methane (Ch4). The radiation material may be sealed in the inner space of the ultraviolet lamp 764 at a constant pressure. The radiation material may be supplied in a gaseous state. For example, the emissive material may be enclosed in the interior space of the ultraviolet lamp 764 at normal or medium pressure. On the other hand, the ultraviolet lamp 764 may be formed to have a somewhat smaller diameter so as to be easily disposed in the internal space of the air conditioner. For example, the ultraviolet lamp 764 may have a diameter of 1 mm to 7 mm or less.

When the ultraviolet lamp 764 is formed with a diameter of 1 mm or less, there is a risk of breakage, and there is a problem that it is difficult to fill the radiant material to be enclosed therein.

When the ultraviolet lamp 764 is formed with a diameter of 7 mm or more, the resistance to the flow of the fluid can be increased by increasing the diameter. Further, there is a problem that the voltage for discharging the charged radiation material in the ultraviolet lamp 764 is increased and the power consumption is increased.

 In addition, the ultraviolet lamp 764 may be formed to be long in the longitudinal direction so as to be disposed in the lateral direction in the internal space of the air conditioner. The thickness of the ultraviolet lamp 764 may be such that the thickness of the ultraviolet lamp 764 can withstand the pressure of the material sealed in the inner space of the ultraviolet lamp 764. [ For example, the ultraviolet lamp 764 may have a thickness of 0.2 mm to 2 mm. The diameter, length, and thickness of the ultraviolet lamp 764 are not limited to the above values.

The first electrode and the second electrode of the ultraviolet lamp 764 may be provided on both sides of the ultraviolet lamp 764. The first electrode and the second electrode may be formed on both sides of the ultraviolet lamp 764 by a conductive solder liquid. Also, the first electrode and the second electrode may be provided by applying a silver paste. The first electrode and the second electrode may be provided by applying carbon nanotubes (CNT) and curing. For example, both ends of the ultraviolet lamp 764 may be placed in a conductive solder solution, The electrodes can be formed at both ends of the ultraviolet lamp 764 by curing.

That is, the outer surface of the ultraviolet lamp 764 can be dipped into the conductive solder liquid, and the manufacturing process is simplified. The conductive material and the conductive solder liquid may include at least one of silver (Ag), carbon nanotube (CNT), copper (Cu), and platinum (Pt). The first electrode and the second electrode of the ultraviolet lamp 764 may be formed in the longitudinal direction of the ultraviolet lamp 764 at both ends of the ultraviolet lamp 764. [ The first electrode and the second electrode may be formed to be at least 1 cm to 3 cm at both ends of the ultraviolet lamp 764.

When the first electrode and the second electrode are formed to be smaller than 1 cm, it is difficult to discharge the radiation material sealed in the ultraviolet lamp 764. That is, the area where the first electrode and the second electrode are provided can be reduced, and the efficiency with which the discharge material can be discharged can be reduced.

If the first electrode and the second electrode are formed to be 3 cm larger, the radiation material sealed in the ultraviolet lamp 764 can be sufficiently discharged, but the area where the first electrode and the second electrode are provided is increased, The area irradiated to the outside can be reduced.

The ultraviolet sterilization module 760 uses a plurality of ultraviolet lamps 764 arranged in parallel to the porous main body 762 to allow the air introduced through the air inlet 712 to pass through the porous main body 762, (750), the harmful substance can be sterilized.

The wavelength of the ultraviolet rays generated from the ultraviolet lamp 764 may be a wavelength in the vicinity of 250 nm to 260 nm which has a high sterilizing power against microorganisms and the ultraviolet ray having a wavelength in the range of 250 nm to 260 nm may have a sterilizing effect 1000 to 10000 times .

When ultraviolet light is irradiated on the DNA of a microorganism, the molecular structure of thymine in the base of DNA can be intensively destroyed. Thymine that absorbs ultraviolet light is pressed against neighboring thymine or cytosine. When thymine is polymerized in this way, DNA replication can not be done properly, so the function as a living organism can be stopped. In addition, ultraviolet rays can oxidize the phospholipid and protein that make up the cell membrane, so that the life activity of bacteria can not be extended.

On the other hand, the ultraviolet sterilization module 760 can be located in various places in the air conditioner. For example, the ultraviolet sterilization module 760 may be located between the front panel 710 of the air conditioner and the front frame (not shown). That is, the porous main body 762 can be coupled to the rear surface of the front panel 710 of the air conditioner so that the ultraviolet lamp 764 faces the heat exchanger 750. This will be described in detail with reference to FIG.

Also, the ultraviolet sterilization module 760 may be positioned between the front frame of the air conditioner and a filter (not shown). That is, the porous main body 762 may be coupled to the rear surface of the front frame so that the ultraviolet lamp 764 faces the heat exchanger 750. This will be described in detail with reference to FIG.

In addition, the ultraviolet sterilization module 760 may be located between the filter frame (not shown) of the air conditioner and the heat exchanger 750. That is, the porous main body 762 can be coupled to the rear side of the filter frame so that the ultraviolet lamp 764 faces the heat exchanger 750. This will be described in detail in FIG.

The metal rail can be electrically connected to the holder 768 and current can be applied to the ultraviolet lamp 764 through the metal rail and holder 768. The metal rail can be connected to a plurality of holders 768 and the current applied to the metal rails can flow to a plurality of holders 768. [ The metal rail may be a parallel connector that connects a plurality of ultraviolet lamps 764 in parallel. The metal rail may be termed a bus bar.

A plurality of holders 768 may be disposed at regular intervals on one side of the metal rail. That is, the plurality of holders 768 may be installed on the metal rail at regular intervals. In this case, the waterproof sealing can be processed to cover not only the electrode, holder 768 of the ultraviolet lamp 764, but also the metal rail.

FIG. 11 is a view for explaining power energy measured in a certain region when one conventional ultraviolet lamp is used. 12 is a view for explaining power energies measured in a certain region when a plurality of ultraviolet lamps according to an embodiment of the present invention are arranged in parallel.

The input / output module 300 may receive a user command or display an operation state of the air conditioner. The input / output module 300 can be connected to the controller 72 to transmit / receive information, display status information of the air such as air pollution, and receive commands from a user.

The pollution detection sensor 410 is a sensor for detecting pollutants present in the air. Contaminants may include fine dust, nitrogen dioxide, carbon monoxide, carbon dioxide, radon, formaldehyde, volatile organic compounds, airborne bacteria, ozone, and asbestos. Such pollutants may be detected by the contamination detection sensor 410, and the sensed information may be transmitted to the control unit 72.

The human body detection sensor 420 is a sensor for detecting the number of persons present in a space where the air conditioner is installed. The human body detection sensor 420 may be a sensor capable of detecting an object using visible light and / or infrared light, and the type of the human body detection sensor 420 is not limited to those described in the present specification. The information sensed by the human body monitoring sensor 420 may be transmitted to the controller 72.

The blower 50 includes a fan motor 52 mounted on the chassis 10, particularly a motor mounting portion 14 formed on the front portion 13, a fan motor 52 mounted on the rotary shaft of the fan motor 52, 12 that are located within the housing. The operation of the fan motor 52 is controlled by the control unit 72. [

The operation of the ultraviolet sterilization module 760 is determined by the control unit 72. The ultraviolet sterilization module 760 may include a plurality of ultraviolet lamps 764 disposed in parallel and may be disposed inside the main body 2 of the air conditioner 700 using ultraviolet light emitted from a plurality of ultraviolet lamps 764. [ It is possible to sterilize air. The ultraviolet sterilizing module 760 can be controlled by the controller 72, respectively, each of the plurality of ultraviolet lamps 764 arranged in parallel.

Although the air conditioner includes the control unit 72, the input / output module 300, the contamination detection sensor 410, the human body detection sensor 420, the blower 50, and the ultraviolet sterilization module 760, It does not.

16 is a flow chart for explaining speed regulation of an ultraviolet sterilization module and a blower fan motor according to an air pollution level in an embodiment of the present invention.

Referring to FIG. 16, the method for controlling the speed of the ultraviolet sterilization module and the fan fan motor includes steps S110 for measuring the amount of air pollution, step S130 for determining an air pollution level, And adjusting the fan motor speed (S150).

The step S110 of measuring the amount of air contamination measures the amount of contamination of the air through the contamination detection sensor 410. [ The pollution detection sensor 410 can measure pollutants in the air. However, the pollution detection sensor 410 can measure pollution amount of air by sorting pollutants in the air. Therefore, pollutants in the air can be distinguished in various ways depending on their causes. For example, gas in the gas range and exhaust gas flowing from the outside are contaminants that can be classified as a by-product of combustion. And coolant fungi, pet by-products, and insects are contaminants related to microorganisms. In other words, pollutants in the air can be divided into various types.

The contamination detection sensor 410 can measure the concentration of air in the air as described above. In addition, the concentration of the separated pollutants can be measured for each type.

The step of determining the air pollution level (S130) determines the air pollution level based on the measured air pollution amount. The air pollution level can be determined in the control unit 72. [ The air pollution level is for determining the degree of operation of the ultraviolet sterilization module 760 and the blower 50 in the air conditioner. For example, the ultraviolet sterilization module 760 can adjust the intensity of ultraviolet rays emitted from the ultraviolet lamp 764 according to the level of contamination of the air. However, the concrete operation method will be described below.

In addition, the air pollution level may have a plurality of pollution levels depending on the pollutants when the pollution detection sensor 410 measures concentrations of pollutants classified by types. For example, if the concentration of the microorganism is high, but the concentration of the fine dust is low, the air pollution level for the microorganism may be high and the air pollution level for the fine dust may be low. Therefore, by setting a different level of pollution depending on the type of air pollutant, the operation corresponding to the type of air pollutant can be performed.

Adjusting the ultraviolet sterilization module and blower fan motor speed according to the air pollution level (S150) may adjust the speed of the ultraviolet sterilization module 760 and the fan motor 50 according to the air pollution level.

17 is a sectional view showing a plurality of ultraviolet lamps of the ultraviolet sterilizing module according to the present invention. Referring to FIG. 17, a description will now be made of the step (S150) of adjusting the ultraviolet sterilization module and the blower fan motor speed according to the air pollution level.

As shown in FIG. 17, the ultraviolet lamp 1110 may include a plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110. However, although FIG. 17 shows a plurality of ultraviolet lamps 10 to illustrate a plurality of ultraviolet lamps, the number of ultraviolet lamps is not limited to ten in the present invention. The control unit 72 can control each of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 according to the air pollution level. For example, the control unit 72 can turn on three lamps of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 if the air pollution level is low. However, when three fixed lamps are operated, the lifetime of a specific ultraviolet lamp may be shortened. Therefore, the control unit can change the lamp periodically operated when only a part of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 operate.

However, the operation period may be a value stored in advance in a predetermined time or may be changed by the control unit 72 according to the state of each ultraviolet lamp. For example, a temperature sensor (not shown) may be included in each of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110, 72, and the control unit 72 stops the operation when the temperature of the specific lamp is equal to or higher than the predetermined reference temperature, and controls the other ultraviolet lamps to perform the operation.

Alternatively, the control unit 72 may store the operation time of each of the plurality of lamps in a memory (not shown), and may include a plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, The operation time of each of the plurality of lamps can be compared with each other, so that the operation can be controlled such that the operation time is relatively low.

In addition, when the air pollution level changes, the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 can be changed. For example, if the air pollution level decreases while the first three ultraviolet lamps are operating, only one ultraviolet lamp may operate, and if the air pollution level increases while the first three ultraviolet lamps are operating, May operate five. That is, the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 can be flexibly changed according to the air pollution level.

Therefore, as described above, even when one conventional ultraviolet lamp 1000 is operated and the power consumption of operating ten ultraviolet lamps 1100 according to one embodiment of the present invention is compared, It is more preferable to use the ultraviolet lamps 1100 according to an embodiment of the present invention than to use a conventional ultraviolet lamp in view of power consumption, space efficiency, and ultraviolet sterilization effect, It is more efficient to use a plurality of ultraviolet lamps 1100 according to the present invention.

Also, the controller 71 can adjust the intensity of the ultraviolet rays emitted by the ultraviolet lamp 1100 according to the air pollution level. Therefore, the power consumption can be managed more efficiently. According to another embodiment, the number of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 and the number of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110, respectively.

Further, the control unit 71 can adjust the fan motor speed of the blower 50 according to the air pollution level.

As described above, the controller 71 controls the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110, The intensity of the ultraviolet rays emitted by each of the lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 and the fan motor speed of the blower 50 can be adjusted, have. For example, it is assumed that the air pollution level is classified into 10 levels, and the control unit 71 determines the number of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108 1109, and 1110 of each of the plurality of ultraviolet lamps 110 operate to operate and the ultraviolet emission intensity of each of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, At the same time, the blower fan motor speed can be controlled to the maximum. The control unit 71 operates five ultraviolet lamps among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, The ultraviolet radiation intensity of each of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 of each of the ultraviolet lamps 110a, , And simultaneously the fan motor speed of the blower 50 can be controlled to be the maximum.

That is, the control unit 71 controls the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, The internal air of the air conditioner is efficiently cleaned by adjusting the intensity of the ultraviolet rays emitted from the respective fans 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, .

In another embodiment, the speed of the fan motor of the blower 50 and the ultraviolet lamp 1100 can be controlled according to the type of contaminants in the controller 71. As described above, when the pollution detection sensor 410 measures concentrations of classified pollutants by type, it can have a plurality of pollution levels according to pollutants. For example, the control unit 71 can measure air pollution levels due to microorganisms and air pollution levels due to fine dusts. If the air pollution level due to microorganisms measured by the control unit is 10 out of 10 levels and the air pollution level due to fine dust is 2 out of 10 levels, the control unit 71 can judge that air pollution due to microorganisms is more severe have. Accordingly, ten ultraviolet lamps among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 operate to remove air contaminants due to microorganisms, The ultraviolet emission intensity of each of the lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 can be maximized. However, in such a case, the fan motor speed of the fan 50 can be made to operate at half the maximum intensity.

For example, the control unit 71 can measure air pollution levels due to microorganisms and air pollution levels due to fine dusts. If the air pollution level due to microorganisms measured by the control unit is 2 out of 10 levels and the air pollution level due to fine dust is 10 out of 10 levels, the control unit 71 judges that air pollution due to fine dust is more severe can do. Therefore, in order to remove air pollutants due to fine dust, some of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 operate, The ultraviolet emission intensity of each of the lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 can be half the maximum. In this case, however, fan 50 speed of blower 50 can be operated at maximum intensity.

That is, according to one embodiment of the present invention, the control unit 71 can determine the cause of the air pollution and obtain an effect that the optimum measures can be taken.

For example, it is assumed that the air control level is classified into 10 levels, and the control unit 71 determines that the air pollution level is 10, the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1109, and 1110 of each of the plurality of ultraviolet lamps 110 operate to operate and the ultraviolet emission intensity of each of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, At the same time, the blower fan motor speed can be controlled to the maximum. The control unit 71 operates five ultraviolet lamps among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 in a control level of 5, The ultraviolet radiation intensity of each of the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 is maximized to three, At the same time, the blower fan motor speed can be controlled to the maximum.

That is, the control unit 71 controls the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110, The fan motor speed can be efficiently controlled by adjusting the intensity of the ultraviolet rays emitted by the respective fans 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, have.
