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.

In addition, the ultraviolet sterilization module 760 may be located 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.

For this operation, the controller 72 can receive information from the input / output module 300, the contamination detection sensor 410, and the like. In addition, the control unit 72 may operate at least two or more of the components included in the air conditioner in combination with each other.

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 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.

The air conditioner includes the control unit 72, the input / output module 300, the contamination detection sensor 410, the blower 50, and the ultraviolet sterilization module 760, but is not limited thereto.

16 is a flowchart for explaining the adjustment of the UV sterilization module according to the air pollution level according to an embodiment of the present invention.

Referring to FIG. 16, the method for controlling the speed of the ultraviolet sterilizing module and the blower fan motor includes the steps of measuring the air condition (S110), determining the cooling sterilizing and deodorizing level (S120) A step S140 of operating the air conditioner, a step S140 of measuring whether the air condition is changed, a step S150 of determining whether the mode is the sterilizing / deodorizing mode only, and the step S160 of performing cooling operation stopping and sterilizing / deodorizing operations can do.

When the input for the operation of the air conditioner is received from the user in preference to the step of measuring the air condition (S110), the controller 72 can operate the air conditioner. Specifically, when an input for the operation of the air conditioner is received from the user, the control unit 72 sucks and mixes air from the outside, and can discharge the harmonized air to the outside.

However, the pollution detection sensor 410 can measure pollution amount of air by sorting pollutants in the air. Therefore, the contamination detection sensor 410 can distinguish the pollutants in the air in various ways according to 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 cooler fungi, pet by-products, insects and so on can be classified into microbial-related pollutants. That is, the contamination detection sensor 410 can variously classify contaminants in the air.

Step S110 of measuring the air condition The contamination amount of the air is measured through the contamination detection sensor 410. The contamination detection sensor 410 can measure contaminants in the air. However, the pollution detection sensor 410 can measure pollution amount of air by sorting pollutants in the air. Therefore, the contamination detection sensor 410 can distinguish the pollutants in the air in various ways according to 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 cooler fungi, pet by-products, insects and so on can be classified into microbial-related pollutants. That is, the contamination detection sensor 410 can variously classify contaminants in the air.

That is, the state of the air in the present invention may include at least one of temperature, humidity, and degree of air pollution. For example, the control unit 72 can divide the air pollution level into 1 to 10 levels, and the control unit 72 can set a plurality of air pollution levels according to each type of the air pollution material.

The step of determining the sterilizing / deodorizing level (S 120) determines at least one of a cooling level, a sterilization level and a deodorization level based on the air condition measured in the step of measuring the air condition (S 110).

The cooling level is used to determine the degree of control of the driving of the heat exchanger 750 to lower the temperature of the air. The higher the level, the stronger the heat exchanger 750. If the level is lower, the heat exchanger 750 is weakly driven do.

Sterilizing module 760 and the fan 740. When the level is high, the ultraviolet sterilizing module 760 and the fan 740 are driven strongly. When the level is low, the ultraviolet sterilizing module 760 and the fan 740 are operated. (760) and the fan (740). However, the ultraviolet sterilization module 760 and the fan 740 may be separately driven according to the sterilization level.

The deodorization level is used to determine the degree of control of the driving of the fan 740 in order to remove the odor in the air. When the level is high, the fan 740 is driven strongly and when the level is low, the fan 740 is driven weakly .

That is, according to the present invention, the driving of each of the ultraviolet sterilizing module, the heat exchanger and the fan can be independently controlled based on the air condition.

The step S130 of operating the air conditioner in a state corresponding to the cooling sterilizing and deodorizing level drives the air conditioner in accordance with the cooling level, the sterilization level and the deodorization level determined in the step S120 of determining the cooling sterilizing deodorization level.

The step of measuring whether the air condition is changed (S140) measures the contamination amount of the air through the contamination detection sensor (410). The contamination detection sensor 410 can measure contaminants in the air. However, the pollution detection sensor 410 can measure pollution amount of air by sorting pollutants in the air. Therefore, the contamination detection sensor 410 can distinguish the pollutants in the air in various ways according to their causes. That is, the step of measuring whether the air condition is changed (S140) measures the state of the air as in the step of measuring the air condition (S110). This includes continuously measuring the state of the air until the state of the air changes.

The step of determining whether the mode is the sterilization and deodorization only mode (S150) and the step of performing the cooling operation stop and the sterilizing / deodorizing operation (S160) determines the state of each of the cooling level, sterilization level and deodorization level, The operation of the heat exchanger 750 for cooling can be stopped. In the sanitization and deodorization-only mode, the ultraviolet sterilization module 760 and the fan 740 can be continuously operated. That is, at least one of the plurality of ultraviolet lamps and the blower can continuously operate even when the operation of the heat exchanger 750 is interrupted.

17 is a sectional view showing a plurality of ultraviolet lamps of the ultraviolet sterilizing module according to the present invention.

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.

In another embodiment, the control unit 72 can control the speed of the fan motor of the ultraviolet lamp 1100 and the fan 50 according to the type of contaminants. 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 72 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 72 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. In this case, however, the blower fan motor speed can be made to operate at half the maximum intensity.

For example, the control unit 72 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 72 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. However, in such a case, the fan motor speed of the blower 50 can be made to operate at the maximum intensity.

That is, according to an embodiment of the present invention, the control unit 72 can determine the cause of the air pollution and can take an optimized measure.

18 is a conceptual diagram for explaining a method of controlling a plurality of ultraviolet lamps according to an embodiment of the present invention.

According to one embodiment of the present invention, when only a part of the ultraviolet lamps of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, The operating lamp can be changed.

For example, if the operation period of each of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 is set to 5 minutes, and the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, and 1107 among the ultraviolet lamps 1101, 1102, 1103, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 are operated by the control unit 72, 1104, 1107, 1105, 1106, 1107, 1108, 1109, and 1110, and other ultraviolet lamps may be operated. That is, the control unit 72 may cause three of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 to operate. Further, when the time is again 5 minutes, the control unit 72 can control another lamp to operate.

The control unit 72 controls the ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109 and 1110 to periodically change the ultraviolet lamps 1101, Can be prevented from being shortened and the problem that the temperature of each ultraviolet lamp increases and the efficiency is reduced can be obtained.

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.

For example, 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, 1110 are operated, it is possible to compare the operation time of each of the plurality of lamps and to control the lamps to operate with a relatively small operation time.

19 is a conceptual diagram for explaining a method of controlling a plurality of ultraviolet lamps according to an embodiment of the present invention.

In one embodiment, the controller 72 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.

For example, when the air pollution level decreases while the first three ultraviolet lamps 1101, 1104, and 1107 are operating, the controller 72 may control the brightness of the first three ultraviolet lamps to be dark.

In another example, when the air pollution level decreases while the first three ultraviolet lamps 1101, 1104, and 1107 are operating, the control unit 72 controls the three ultraviolet lamps 1103, 1105, The brightness of the three ultraviolet lamps 1103, 1105, and 1110 different from those of the first three ultraviolet lamps can be controlled to be darker than that of the first three ultraviolet lamps.

In another embodiment, only the brightness of some ultraviolet lamps can be controlled, and in some cases, some ultraviolet lamps may stop operating while some ultraviolet lamps remain in operation. That is, the control unit may arbitrarily determine whether the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 operate and brightness according to the air pollution level.

As described above, according to the present invention, the brightness of each of the plurality of ultraviolet lamps can be changed according to the air pollution level.

20 is a conceptual diagram for explaining a method of controlling a plurality of ultraviolet lamps according to an embodiment of the present invention.

In another embodiment, the number of ultraviolet lamps operating among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 can be changed when the air pollution level changes. For example, if the air pollution level decreases while the first three ultraviolet lamps 1101, 1104, and 1107 are operating, only two ultraviolet lamps 1103 and 1106 may operate. That is, the control unit 72 may control the two ultraviolet lamps 1101, 1104, and 1107 to operate, and the plurality of ultraviolet lamps 1101, 1104, The control unit 72 may control the two ultraviolet lamps to operate.

In addition, if the air pollution level increases while the first three ultraviolet lamps are operating, five ultraviolet lamps may operate. 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.

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, 1104, 1105, 1106, 1107, 1108, 1109, and 1110, respectively.

That is, the control unit 72 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, .

FIG. 21 is a flowchart for explaining control of an ultraviolet sterilization module according to an air pollution level according to an embodiment of the present invention.

In step S210, when the user's command is input, the control unit may enter the sterilization and deodorization-only mode. In the sterilization and deodorization-only mode, when the power OFF command is input, sterilization is performed when the air pollution degree is equal to or higher than a predetermined reference value. The power of the air conditioner driven in the deodorization-only mode is not cut off. In other words, when the operation is performed in the sterilization and deodorization only mode, the power input to the heat exchanger is cut off and the operation of the ultraviolet sterilization module is maintained without disconnecting the power even if the user receives the power OFF command.

In the step S230 of analyzing the cause of pollution, the degree of the air pollution can be analyzed by the pollutant source as described above.

Further, in the step S250 of operating the fan and the plurality of ultraviolet lamps in response to the cause of the contamination, the operation of the fan or the plurality of ultraviolet lamps can be independently controlled according to the cause of the contamination as described above.

In one embodiment, the display unit displays a state of the air and a state of the air conditioner, and the control unit displays the state of the air, the heat exchanger, the fan, and the ultraviolet sterilization module on the display unit, The condition of the air conditioner can be known.
