In the main body 700 , the air inlet 712 may be formed on the upper surface of the air conditioner, and the air outlet 714 may be formed on the lower surface of the air conditioner. The main body 700 is arranged such that the air inlet 712 is formed on the upper surface of the air conditioner, 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. It is also possible to be

In the main body 700 , the air inlet 712 is formed on the upper side of the air conditioner, particularly the upper surface side of the air conditioner, and the air outlet 714 is formed on the lower side of the air conditioner, particularly the lower surface side of the air conditioner. . In addition, it will be described that the front panel 710 is rotated to protrude forward with the center of the upper part for service and the like inside the air conditioner while forming the front exterior of the air conditioner.

In addition, the structure and functions of the front panel 710, the chassis 720, the wind direction control member 730, the fan 740, and the heat exchanger 750 in the main body 700 according to an embodiment of the present invention are shown in FIG. 1 As described with reference to FIGS. to 4 , duplicate descriptions are excluded.

The ultraviolet sterilization 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 UV 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 may pass, and a plurality of holes 766 through which air may pass may be formed in the porous main body 762 . The porous main body 762 may be composed of a porous plate in which a plurality of holes 766 are formed, and of course it is also possible to be composed of a wire assembly in which a plurality of wires are cross-connected. When the porous main body 762 is composed of a wire assembly, a hole 766 through which air can pass may be formed between the plurality of wires. Hereinafter, the porous main body 762 may be referred to as a mesh, a web, a main body, a body, a support body, a porous ramp support body, a web main body, a mesh body, a web body, and the like.

A hole 766 through which air flows toward the ultraviolet lamp 764 may be formed in the porous main body 762 . In the hole 766 , a hole 766 having a predetermined size or larger may be formed to minimize flow resistance caused by the porous main body 762 . In addition, the porous main body 762 can be made of an elastic material, has a round-type curved surface to correspond to the shape of the heat exchanger 750 or has a shape bent at least once, and the body 700 and the heat exchanger ( 750) may be located inside.

The UV sterilization module 760 may emit heat from the UV lamp 764 , and the porous main body 762 is preferably formed of a material having high heat resistance. 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 an aluminum (Al) material. 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 flow direction of the air. When the photocatalytic material is applied to the surface of the porous main body 762 , air may be deodorized by the porous main body 762 and then flow to the ultraviolet lamp 764 and the heat exchanger 750 . That is, when the photocatalytic material is applied to the surface of the porous main body 762 , adsorption of the deodorizing component in the air to the surface of the ultraviolet lamp 764 can be minimized. It is possible to minimize the degradation of the performance of the ultraviolet lamp 764 that may occur when the deodorizing component is excessively adsorbed on the surface of the ultraviolet lamp 764 .

For example, the photocatalytic material formed on the surface of the porous main body 762 includes titanium oxide (TiO2), zinc oxide (ZnO), cadmium sulfide (CdS), zirconia (ZrO2), vanadium oxide (V2O3), tungsten oxide catalyst ( WO3) and the like may be included. The air sucked in through the air inlet 712 is primarily deodorized in the porous main body 762, and can be secondarily sterilized by the ultraviolet lamp 764, and the deodorized and sterilized air in the heat exchanger 750 is can be inhaled.

On the other hand, even if the porous main body 762 is disposed in a space in which the gas flows, it is possible to minimize interference with the flow of the gas. In addition, in the process 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 to which the ultraviolet rays are irradiated may be increased. Accordingly, the sterilization power of the ultraviolet sterilization module 760 may be increased.

The UV sterilization module 760 may include a plurality of UV lamps 764 , and the plurality of UV lamps 764 may be disposed to be spaced apart from each other in the porous main body 762 . At least some of the plurality of ultraviolet lamps 764 may be arranged side by side. The plurality of UV lamps 764 may all be arranged side by side. The plurality of ultraviolet lamps 764 may be disposed on the porous main body 762 with a predetermined interval. A plurality of ultraviolet lamps 764 may be arranged in parallel.

The plurality of ultraviolet lamps 764 may be disposed to be spaced apart from both surfaces of the porous main body 762 . The plurality of ultraviolet lamps 764 may be all located between the porous main body 762 and the heat exchanger 750 in the air flow direction. In addition, it is possible that a part is disposed 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 may primarily sterilize the air passing between the air intake 712 and the porous main body 762 . In addition, the ultraviolet lamp disposed between the porous main body 762 and the heat exchanger 750 may secondarily sterilize the air that has passed through the porous main body 762 .

As described above, the ultraviolet lamp may be dispersedly disposed on the porous main body 762 , and a photocatalytic material may be coated on the porous main body 762 . As a result, air can be primarily sterilized between the air intake port 712 and the porous main body 762 . Furthermore, when deodorized by the porous main body 762 , it may be secondarily sterilized between the porous main body 762 and the heat exchanger 750 .

The UV sterilization module 760 may include a holder (not shown) for supporting the UV lamp 764 . The holder may support the UV lamp 764 so that the UV lamp 764 is spaced apart from the porous main body 762 . A plurality of holders may support the ultraviolet lamp 764 , and a pair of holders may support the ultraviolet lamp 764 . The UV sterilization module 760 may include a plurality of pairs of holders. A plurality of pairs of holders may be disposed at regular intervals in 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 an electric wire (not shown).

The ultraviolet lamp 764 may be provided as an external electrode having an external electrode. Accordingly, the first electrode may be provided on one side of the ultraviolet lamp 764 and the second electrode may be provided on the other side of the ultraviolet lamp 764 . In addition, the first electrode and the second electrode may be provided by applying a conductive solder solution from the outside of the UV lamp 764 . In addition, the first electrode and the second electrode may be provided by applying silver paste. In addition, the first electrode and the second electrode may be provided by coating and curing carbon nanotubes (CNT). That is, the ultraviolet lamp 764 and the first electrode and the second electrode are provided separately, and an electric field may be formed between the first electrode and the second electrode. In addition, a discharge is induced in the radiation material inside the ultraviolet lamp 764 by the electric field and may generate ultraviolet rays. Accordingly, since the first electrode and the second electrode do not come into contact with the material enclosed in the ultraviolet lamp 764 , heat that can be generated from the ultraviolet lamp 764 is reduced, and the lifespan of the ultraviolet lamp 764 is reduced. can be increased.

The power supply may supply power to the UV lamp 764 . In addition, the power supply unit may stabilize the current supplied to the ultraviolet lamp 764 . In addition, the power supply may generate a required high voltage for generating ultraviolet rays from the ultraviolet lamp 764 . That is, the power supply may be provided by changing the output frequency and the driving voltage according to the driving frequency and 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 may connect the power supply and the plurality of UV lamps 764 . In detail, the electric wire may connect the first electrode and the second electrode to the power supply. In addition, the electric wire may connect the plurality of ultraviolet lamps 764 and the power supply in parallel. That is, by connecting the power supply unit and the plurality of ultraviolet lamps 764 in parallel, the plurality of ultraviolet lamps 764 may be operated simultaneously. And, even when one of the plurality of UV lamps 764 is defective, there is an advantage of easy maintenance.

Meanwhile, although 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 outside, 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 ultraviolet lamp 764 of the external electrode fluorescent lamp type may be formed in the shape of a bar or tube in which an inner space is formed. And, the ultraviolet lamp 764 may be formed to be shielded to have a sealed inner space. The ultraviolet lamp 764 may be formed of one of quartz, borosilicate, and glass containing the quartz or borosilicate. In addition, a radiation material capable of generating the ultraviolet rays may be enclosed in the inner space of the ultraviolet lamp 764 . The radiation material may be discharged by the first electrode and the second electrode respectively disposed on both sides of the UV lamp 764 to generate UV light.

For example, the radiation material in the ultraviolet lamp 764 includes mercury (Hg), neon (Ne), xenon (Xe), krypton (Kr), argon (Ar), xenon bromide (XeBr), xenon chloride (XeCl), At least one of krypton bromide (KrBr), krypton chloride (KrCl), and methane (Ch4) may be included. In addition, most materials other than mercury (Hg) among the radiation material 103 may be provided in a gaseous state. Further, the radiation material may be sealed at a constant pressure in the inner space of the ultraviolet lamp 764 . For example, the radiation material may be enclosed in the inner space of the ultraviolet lamp 764 under normal or medium pressure. Meanwhile, the ultraviolet lamp 764 may have a rather small diameter so that it can be easily disposed in the inner space of the air conditioner. For example, the ultraviolet lamp 764 may have a diameter of 1 mm to 7 mm or less.

If the ultraviolet lamp 764 is formed with a diameter of 1 mm or less, there is a risk of damage, and there is a problem in that it is difficult to fill the radiation material enclosed therein.

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

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

The first electrode and the second electrode of the UV lamp 764 may be provided on both sides of the outside of the UV lamp 764 . In addition, the first electrode and the second electrode may be formed by a conductive solder solution on both sides of the ultraviolet lamp 764 . In addition, the first electrode and the second electrode may be provided by applying silver paste. In addition, the first electrode and the second electrode may be provided by coating and curing carbon nanotubes (CNT). For example, both ends of the ultraviolet lamp 764 are put in a conductive solder solution, and the conductive solder solution By curing, electrodes may be formed at both ends of the ultraviolet lamp 764 .

That is, the outer surface of the ultraviolet lamp 764 can be dipping in the conductive solder solution, and has the advantage of simplifying the manufacturing process. In addition, the conductive material and the conductive solder solution may include one or more of silver (Ag), carbon nanotubes (CNT), copper (Cu), and platinum (Pt). Accordingly, the first electrode and the second electrode of the ultraviolet lamp 764 may be formed at both ends of the ultraviolet lamp 764 in the longitudinal direction of the ultraviolet lamp 764 . In addition, the first electrode and the second electrode may be formed to be at least 1 cm to about 3 cm from both ends of the ultraviolet lamp 764 .

When the first electrode and the second electrode are formed to be smaller than 1 cm, there is a problem in that it is difficult to discharge the radiation material enclosed in the ultraviolet lamp 764 . That is, an area in which the first electrode and the second electrode are provided is reduced, so that the efficiency of discharging the radiation material may be reduced.

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

The ultraviolet sterilization module 760 uses a plurality of ultraviolet lamps 764 disposed in parallel on the porous main body 762 to allow the air introduced through the air intake 712 to pass through the porous main body 762 to be a heat exchanger. When heading to 750, you can sterilize harmful substances.

The wavelength of ultraviolet light generated by the ultraviolet lamp 764 may be a wavelength near 250 nm to 260 nm, which has a high sterilization power against microorganisms, and ultraviolet rays having a wavelength of 250 nm to 260 nm have a sterilization effect of 1000 to 10000 times than that of near ultraviolet. can

When ultraviolet rays are irradiated to the DNA of microorganisms, the molecular structure of thymine among the bases of DNA can be intensively destroyed. Thymine that absorbs UV light sticks to neighboring thymine or cytosine. When thymine is polymerized in this way, DNA replication cannot be performed properly, so the function as a living organism may be stopped. In addition, UV rays can oxidize the phospholipids and proteins that make up the cell membrane, preventing the life activities of bacteria from being extended.

Meanwhile, the UV sterilization module 760 may be located in various places in the air conditioner. For example, the UV sterilization module 760 may be located between the front panel 710 of the air conditioner and a front frame (not shown). That is, the porous main body 762 may 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. 13 .

The input/output module 300 may be connected to the control unit 72 to transmit/receive information, may display air condition information such as air pollution level, and may receive a command from a user.

The pollution sensor 410 is a sensor that detects contaminants present in the air. Pollutants may include fine dust, nitrogen dioxide, carbon monoxide, carbon dioxide, radon, formaldehyde, volatile organic compounds, airborne bacteria, ozone, and asbestos. These pollutants are detected by the pollution detection sensor 410 , and the detected information may be transmitted to the control unit 72 .

The human body sensor 420 is a sensor for detecting the number of people present in the 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 thereof is not limited to those described herein.

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

According to FIG. 16 , the method of controlling the speed of the UV sterilization module and the blower fan motor includes the steps of measuring the air pollution amount (S110), determining the air pollution level (S130), and the UV sterilization module and the blower according to the air pollution level It may include adjusting the fan motor speed (S150).

In the step of measuring the amount of air pollution ( S110 ), the amount of air pollution is measured through the pollution sensor 410 . The pollution sensor 410 may measure contaminants in the air. However, the pollution detection sensor 410 can measure the amount of pollution in the air by classifying the pollutants in the air. Therefore, pollutants in the air can be classified in various ways according to the cause of their generation. For example, gas of a gas range or exhaust gas flowing in from the outside is a pollutant that can be classified as a by-product of combustion. And air conditioner mold, pet by-products, insects, etc. are contaminants related to microorganisms. In other words, pollutants in the air can be classified in various ways.

The pollution sensor 410 may measure the concentration of the pollutant in the air as described above. In addition, the concentration of the classified pollutants may be measured for each type.

In the step of determining the air pollution level ( S130 ), the air pollution level is determined based on the measured air pollution amount. The air pollution level may be determined in the control unit 72 . The air pollution level is to determine 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 may adjust the intensity of ultraviolet rays emitted from the ultraviolet lamp 764 according to the level of pollution in the air. However, a specific operation method will be described later.

In addition, the air pollution level may have a plurality of pollution levels according to the pollutants when the pollution detection sensor 410 measures the concentration of the classified pollutants by type. For example, if the concentration of microorganisms is high but the concentration of fine dust is low, the air pollution level for microorganisms may be high and the air pollution level for fine dust may be low. Accordingly, by setting a separate pollution level according to the type of the air pollutant, a corresponding operation may be performed according to the type of the air pollutant.

In the step of adjusting the speed of the UV sterilization module and the fan motor of the blower according to the air pollution level ( S150 ), the speed of the UV sterilization module 760 and the fan motor of the blower 50 may be adjusted according to the level of the air pollution.

17 is a cross-sectional view showing a plurality of ultraviolet lamps of the ultraviolet sterilization module according to the present invention. The step (S150) of adjusting the speed of the ultraviolet sterilization module and the blower fan motor according to the air pollution level will be described with reference to FIG. 17 .

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 UV lamps to illustrate the plurality of UV lamps as an example, the number of UV lamps is not limited to 10 in the present invention. The controller 72 may 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, when the air pollution level is low, the controller 72 may turn on three lamps of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110. However, when three fixed lamps are operated, the lifespan of a specific UV lamp may be shortened. Accordingly, when only some of the plurality of UV lamps 1101 , 1102 , 1103 , 1104 , 1105 , 1106 , 1107 , 1108 , 1109 and 1110 operate, the controller may change the periodically operated lamp.

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

Alternatively, the control unit 72 stores the operating time of each of the plurality of lamps in a memory (not shown), and some of the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110. In the case of operating only the lamp of , the operation time of each of a plurality of lamps may be compared, and a lamp having a relatively short operation time may be controlled to be operated with priority.

In addition, when the air pollution level changes, the number of UV lamps operating among the plurality of UV lamps 1101 , 1102 , 1103 , 1104 , 1105 , 1106 , 1107 , 1108 , 1109 and 1110 may be changed. For example, if the air pollution level decreases while the first 3 UV lamps are in operation, only one UV lamp can operate, and when the air pollution level increases while the first 3 UV lamps are operating, the UV lamp 5 may work. That is, the number of operating UV lamps among the plurality of UV lamps 1101 , 1102 , 1103 , 1104 , 1105 , 1106 , 1107 , 1108 , 1109 and 1110 may be flexibly changed according to the air pollution level.

Therefore, as described above, even if the power consumption of operating one conventional UV lamp 1000 and operating 10 UV lamps 1100 according to an embodiment of the present invention is compared, the embodiment of the present invention Since it consumes lower power to simultaneously operate 10 UV lamps 1100 by It is more efficient to use a plurality of ultraviolet lamps 1100 by

In addition, the controller 71 may adjust the intensity of the ultraviolet rays emitted by the ultraviolet lamp 1100 according to the level of air pollution. Therefore, power consumption can be managed more efficiently. And, according to another embodiment, the number of UV lamps operating among the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 and the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110) may adjust the intensity of the ultraviolet rays emitted by each.

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

As described above, the control unit 71 controls the number of UV lamps operating among the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, and 1110 according to the air pollution level, and a plurality of UV lamps. 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 speed of the blower 50 fan motor can be adjusted, respectively, and each can be adjusted independently at the same time have. For example, it is assumed that the air pollution level is classified into 10 steps, and when the air pollution level is 10, the control unit 71 includes a plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108. , 1109, 1110) of 10 UV lamps operate, and the UV emission intensity of each of the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 is maximum, At the same time, the fan motor speed of the blower 50 may be controlled to be maximum. In addition, when the air pollution level is 5, the control unit 71 operates five ultraviolet lamps among the plurality of ultraviolet lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110, and a plurality of of the UV lamps (1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110), the UV emission intensity of 3 is the maximum, and the other two are half the maximum UV emission intensity. , it is possible to control the fan motor speed of the blower 50 to the maximum at the same time.

That is, the controller 71 controls the number of UV lamps operating among the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 according to the air pollution level, the plurality of UV lamps ( 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110) It is possible to efficiently purify the internal air of the air conditioner by controlling the intensity of each of the ultraviolet rays and the speed of the blower 50 fan motor. can

Also, in another embodiment, the controller 71 may control the speed of the ultraviolet lamp 1100 and the fan motor of the blower 50 according to the type of pollutant. As described above, when the pollution detection sensor 410 measures the concentration of the classified pollutants for each type, it may have a plurality of contamination levels according to the pollutants. For example, the controller 71 may measure the air pollution level due to microorganisms and the air pollution level due to fine dust separately. 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 may determine that the air pollution due to microorganisms is more severe. have. Therefore, in order to well remove air pollutants caused by microorganisms, 10 UV lamps among the plurality of UV lamps 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110 are operated, and a plurality of UV lamps are operated. Each of the lamps 1101 , 1102 , 1103 , 1104 , 1105 , 1106 , 1107 , 1108 , 1109 , and 1110 may have a maximum UV emission intensity. However, in this case, the fan motor speed of the blower 50 may be operated at half the maximum intensity.

For another example, the controller 71 may measure the air pollution level due to microorganisms and the air pollution level due to fine dust separately. 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 determines that the air pollution due to fine dust is more severe. can do. Therefore, some of the UV lamps (1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, 1110) operate in order to well remove air pollutants caused by fine dust. Each of the lamps 1101 , 1102 , 1103 , 1104 , 1105 , 1106 , 1107 , 1108 , 1109 , and 1110 emits UV light at half the maximum. However, in this case, the fan motor speed of the blower 50 may be operated at the maximum intensity.

That is, according to one embodiment of the present invention, the control unit 71 can obtain the effect of determining the cause of air pollution and taking an optimized action therefor.
