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.

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.

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.

In addition, the porous main body 762 may have a plurality of holders 768 at regular intervals on both sides. The plurality of holders 768 may be made of a metal material and may be formed to surround a part of the outer circumferential surface of the ultraviolet lamp 764.

In addition, the porous main body 762 may have a holder 768 at regular intervals on both sides of the transverse side in one side, and both sides of the ultraviolet lamp 764 may be coupled to the holder 768, respectively.

The porous main body 762 may include a left side portion, a center portion, and a right side portion of the ultraviolet lamp 764, can do.

The porous main body 762 may be waterproof sealed (not shown) on the periphery of the holder 768 to prevent corrosion of the electrodes and the holder 768 of the ultraviolet lamp 764 on one side.

8, the ultraviolet sterilization module 760 may include a metal rail (not shown) disposed in the porous main body 762. 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.

The porous main body 762 may include a holder (not shown) for supporting an ultraviolet lamp 764 and an ultraviolet lamp 764 may be coupled to a holder located at regular intervals in the porous main body 762 . The ultraviolet sterilization module 760 uses an ultraviolet lamp 764 coupled 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 to the heat exchanger 750 ), The harmful substance can be sterilized.

As described above, the porous main body 762 is made of an elastic material so as to cover the entire surface of the heat exchanger 750, and is formed in a shape similar to the shape of the heat exchanger 750 and coupled to the upper side of the heat exchanger 750 .

In addition, although not shown in FIG. 9, the porous main body of the ultraviolet sterilizing module 760 according to an embodiment of the present invention may be manufactured in various shapes corresponding to the size and shape of the ultraviolet lamp.

10 is a view for explaining an example in which the ultraviolet sterilization module according to an embodiment of the present invention includes a metal rail.

10, the ultraviolet sterilization module 760 according to an embodiment of the present invention includes a porous main body 762, a plurality of ultraviolet lamps 764, a plurality of holes 766, (768) and a metal rail (769).

Air can be introduced through the plurality of holes 766 of the porous main body 762. Air passing through the plurality of holes 766 can be sterilized by the plurality of ultraviolet lamps 764. [ The metal rail 769 may be installed on the left and right portions of the porous main body 762 by a predetermined length. The plurality of holders 768 may be installed on the metal rail 769 at a predetermined distance. As a result, a plurality of holders 768 may be installed in the left and right portions of the porous main body 762.

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.

In FIG. 11, it is assumed that ultraviolet ray sterilization is performed using one conventional ultraviolet lamp 1000, and in FIG. 12, ultraviolet sterilization is performed by arranging ten ultraviolet lamps 1100 according to an embodiment of the present invention in parallel .

11, when the conventional ultraviolet lamp 1000 is operated, the power energy measured in region A is 5 mW / cm ² , the power energy measured in region B is 2.2 mW / cm ² , The power energy measured in the D region is 0.6 mW / cm ² and the measured power energy in the D region is 0.9 mW / cm ² .

12, when ten ultraviolet lamps 1100 according to an embodiment of the present invention are arranged in parallel, the power energy measured in region A is 5.1 mW / cm ² , and in region B, electrical energy which is measured is a 4.5mW / cm ^2, electric energy is measured in the region C is electrical energy measured at 3.6mW / cm ² and the D domain is 3.7mW / cm ^2.

That is, when a plurality of ultraviolet lamps 1100 according to an embodiment of the present invention having a very small diameter are arranged in parallel and operated at the same time, a higher power density is obtained as the interval is narrower due to the overlap effect. Conversely, the wider the gap, the less the effect of superposition.

It is possible to consume lower power by simultaneously operating ten ultraviolet lamps 1100 of the present invention than by operating one conventional ultraviolet lamp 1000 in practice. Therefore, it is more efficient to use a plurality of ultraviolet lamps 1100 according to an embodiment of the present invention than to use a conventional ultraviolet lamp, considering power consumption, space efficiency, and ultraviolet sterilization effect.

FIG. 13 is a view for explaining an ultraviolet sterilizing module according to the first embodiment of the present invention, and FIG. 14 is a cross-sectional view of the air conditioner including the ultraviolet sterilizing module according to the first embodiment of the present invention.

Hereinafter, the same or similar parts as those in the preceding description will be omitted and differences will be mainly described.

13 and 14, the ultraviolet sterilization module 760 according to the present embodiment includes a porous main body 762, an ultraviolet lamp 764, a plurality of holes 766 provided in the porous main body 762, A holder 768, and the like.

The porous main body 762 may be a conductor.

The external electrode fluorescent lamp type ultraviolet lamp 764 can emit a high heat and the porous main body 762 provided with the ultraviolet lamp 764 can be made to have a durability due to deterioration due to high heat emitted from the ultraviolet lamp 764 Problems can arise.

In addition, since the refrigerant in the air conditioner exchanges heat with the air in the heat exchanger 750, condensation may occur and humidity inside the main body may be high.

Accordingly, the porous main body 762 may be a porous metal body having high durability against heat and moisture. In other words, the porous main body 762 may be formed of a metal material, preferably an aluminum material.

The porous main body 762 may include a holder mounting portion 765 and a through hole 763.

A plurality of holes 766 through which air can pass may be formed in the through-hole 763.

The through hole 763 may be provided with a plurality of holes 766 through which air passes and from which the outgoing light of the ultraviolet lamp is irradiated.

The holder mounting portion 765 may be equipped with a holder 768. [ Or the porous main body 762 does not include a separate holder mounting portion 765 and the holder 768 can be mounted on the passage portion 763. [ Hereinafter, the case where the porous main body 762 includes the holder mounting portion 765 will be described as an example.

A plurality of holes 766 are formed in the through-hole 763 to allow air to pass therethrough. The through hole 763 may be formed of a metal, preferably an aluminum (Al) material.

The holder mounting portion 765 may be provided with a holder 768. [ The holder mounting portion 765 may be formed of a metal, preferably an aluminum (Al) material. Alternatively, the holder mounting portion 765 may be formed of an insulating material such as plastic, to which current can not be applied.

The holder mounting portion 765 may be formed by extending the edge of the passage portion 763. The holder mounting portion 765 and the passage portion 763 may be integrally formed.

The holder mounting portion 765 may be formed by extending a part of the edge of the passage portion 763. For example, when the holder 768 is disposed at the left and right edges of the porous main body 762, the holder mounting portion 765 may be formed by extending left and right edges of the passage portion 763.

In order to stably support the holder 768 and the ultraviolet lamp 764, the thickness of the holder mounting portion 765 may be thicker than the thickness of the through hole 763. [

The holder mounting portion 765 may be formed at both edge regions of the porous main body 762. For example, the holder mounting portion 765 may be formed in the left and right edge regions of the porous main body 762. However, the position of the holder mounting portion 765 is not limited thereto.

The ultraviolet lamp 764 corresponding to the holder mounting portion 765 can not irradiate the ultraviolet rays toward the porous main body 762 due to the holder 768 so that the hole 766 may not be formed in the holder mounting portion 765 have. Therefore, the manufacturing cost can be reduced when the porous main body 762 includes the holder mounting portion 765 as compared with the case where the entire porous main body 762 is formed by the passage portion 763.

On the other hand, the ultraviolet lamp 764 may be disposed on one side of the porous main body 762 facing the heat exchanger 750.

A plurality of ultraviolet lamps 764 may be positioned between the porous main body 762 and the heat exchanger 750.

[ More specifically, when the ultraviolet lamp 764 is disposed in the transverse direction with respect to the porous main body 762, the porous main body 762 may be formed longer in the lateral direction than in the longitudinal direction.

The air having passed through the hole 766 formed in the passage 763 of the porous main body 762 can be sterilized by the ultraviolet lamp 764 so that the ultraviolet lamp 764 is arranged to face the passage 763. [ . That is, the ultraviolet lamp 764 may be arranged corresponding to the passage 763.

The ultraviolet lamp 764 may include an external electrode 764a and a lamp body 764b. External electrodes 764a may be provided at both ends of the lamp body 764b. The external electrode 764a may be a first electrode and a second electrode.

The ultraviolet sterilization module 760 may be connected to a power supply such as an inverter through a wire. When a voltage is applied between the inverter and the external electrode 764a at both ends of the ultraviolet lamp 764 by the electric wire, ultraviolet rays may be irradiated from the lamp body 764b. The ultraviolet light irradiated from the lamp body 764b can sterilize the air passing through the heat exchanger 750 surface and the ultraviolet sterilization module 760.

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.

The plurality of ultraviolet lamps 764 may be arranged in parallel with predetermined intervals.

The plurality of ultraviolet lamps 764 may be arranged side by side.

The length of the porous main body 762 may be longer than the length of the ultraviolet lamp 764 to prevent the ultraviolet lamp 764 from protruding to the side of the porous main body 762. [

The ultraviolet sterilization module 760 may include a holder 768 for supporting the ultraviolet lamp 764. In more detail, the ultraviolet sterilization module 760 may include a plurality of pairs of holders 768 spaced apart from one another on one side of the porous main body 762.

In addition, one porous main body 762 can protect a plurality of ultraviolet lamps 764 and can support a plurality of ultraviolet lamps 764, thereby minimizing the number of parts.

In order to maximize the flow of air through the porous main body 762, the shape of the hole 766 may be a honeycomb shape having a regular hexagon. Alternatively, the arrangement of the plurality of holes 766 is the same as the honeycomb shape, and the shape of the holes 766 may be circular. At this time, the area occupied by the holes 766 per unit area of the porous main body 762 can be maximized, so that the flow of air can be smooth.

On the other hand, heat may be generated in the ultraviolet lamp 764 included in the ultraviolet sterilizing module 760, and the efficiency of the heat exchange occurring between the refrigerant and the air in the heat exchanger 750 due to the heat may be reduced. Accordingly, the ultraviolet sterilization module 760 and the heat exchanger 750 may be spaced apart from each other by a predetermined distance.

FIG. 15 is a plan view for explaining an ultraviolet sterilization module according to a second embodiment of the present invention, and FIG. 16 is a perspective view for explaining an ultraviolet sterilization module according to a second embodiment of the present invention.

Hereinafter, the same contents as those described above will be omitted and the differences will be mainly described.

15 and 16, in the ultraviolet sterilizing module 760 according to the present embodiment, the density of holes formed in the porous main body 762 may vary depending on the through hole position.

 The density of the holes 766 formed in the passage 763 of the porous main body 762 may decrease as the distance from the center area CT of the porous main body 762 increases. In this case, the density of holes 766 may mean the number of holes 766 existing per unit area of the through-hole 763.

In the central region CT, the density of the holes 766 may be constant. The central region CT may be a region including a center of the porous main body 762 and having a predetermined width. The central region CT may have an elliptical shape with the longitudinal direction of the ultraviolet lamp 764 as the major axis.

The central region CT may mean the central region of the passage 763 when the region where the ultraviolet lamp 764 faces the porous main body 762 is the entire passage 763. [

On the other hand, when the region of the porous main body 762 facing the ultraviolet lamp 764 is a part of the passage 763, the central region CT is formed in a part of the passage 763 facing the ultraviolet lamp 764 May refer to the central region of the < RTI ID = 0.0 >

The density of the holes 766 formed in the porous main body 762 may decrease as the distance from the central region CT of the porous main body 762 increases in the longitudinal direction of the ultraviolet lamp 764, The direction perpendicular to the longitudinal direction of the ultraviolet ray lamp 764 of the first embodiment.

The density of the holes 766 formed in the porous main body 762 may decrease as the distance from the central region of the porous main body 762 increases in the direction perpendicular to the longitudinal direction of the ultraviolet lamp 764, 762 may be constant with respect to the longitudinal direction of the ultraviolet lamp 764. [

The density of the holes 766 formed in the porous main body 762 is determined in the longitudinal direction of the ultraviolet lamp 764 and in the direction perpendicular to the longitudinal direction of the ultraviolet lamp 764 in the central region CT of the porous main body 762 The more you can get away with it, the less you can get.

The ultraviolet sterilization module 760 includes a porous main body 762 having a plurality of holes 766 and a plurality of ultraviolet lamps 764 coupled to the porous main body 762, The plurality of ultraviolet lamps 764 may be arranged in parallel with each other.

At this time, the sterilizing effect by the ultraviolet lamp 764 can be weakened toward the edge from the central region CT of the porous main body 762.

The germicidal effect of the ultraviolet ray is weakened as the distance from the ultraviolet lamp 764, which is the light source of the ultraviolet light, decreases, and the reduction of the germicidal effect can be compensated by overlapping the plurality of ultraviolet lamps 764. In the central region CT of the porous main body 762, this overlap effect can be kept constant. However, as the distance from the central region CT of the porous main body 762 increases, the effect of superimposing is reduced, and the sterilizing effect of the ultraviolet lamp 764 is weakened. This can be confirmed by the values shown in Fig.

When the density of the holes 766 formed in the porous main body 762 is reduced as it moves from the central region CT of the porous main body 762 to the edge of the porous main body 762, The flow rate of the air passing through the holes 766 can be reduced as the flow rate of the air is greatest in the central region CT of the porous main body 762 and moved to the edge region of the porous main body 762.

Therefore, a large amount of air passes through the area where the sterilizing effect is strong, and a relatively small amount of air passes through the area where the sterilizing effect is weak. Therefore, the air sucked into the air conditioner is guided by the ultraviolet lamp 764 It is possible to sterilize it more effectively.

When the porous main body 762 has at least one more folded shape, the porous main body 762 may have at least two planes. In this case, each plane forming the porous main body 762 may have a central region CT, and the density of the holes 766 formed in each plane may decrease as the distance from the central region CT increases .

The ultraviolet sterilization module 760 according to the present embodiment may have a maximum through-hole area in the central region CT. In this case, the central region CT may mean a region where the sterilizing effect by the ultraviolet lamp 764 is maximum. Accordingly, if the arrangement of the ultraviolet lamps 764 is changed, the number, size, and the like of the central region CT can be changed.

Accordingly, it is apparent that the density of the holes 766 formed in the porous metal body 762 may vary depending on the shape and arrangement of the ultraviolet lamp 764. [ For example, the density of the holes 766 may decrease from the center point of the porous metal body 762 toward the edge.

FIG. 17 is a plan view for explaining an ultraviolet sterilizing module according to a third embodiment of the present invention, and FIG. 18 is a perspective view for explaining an ultraviolet sterilizing module according to a third embodiment of the present invention.

Since the ultraviolet sterilizing module 760 according to the third embodiment is the same as the ultraviolet sterilizing module 760 according to the second embodiment in the central area CT, a description thereof will be omitted and the differences will be mainly described.

17 and 18, the size of the holes formed in the porous main body 762 of the ultraviolet sterilization module 760 according to the present embodiment may vary depending on the positions of the through holes.

The size of the holes 766 formed in the porous main body 762 may be reduced as the distance from the central region CT of the porous main body 762 increases. For example, if the hole 766 is circular, the diameter of the hole 766 may be smaller the further away from the central region CT of the porous metal body 762.

In the central region CT, the size of the hole 766 may be constant.

The size of the holes 766 formed in the porous main body 762 can be reduced as the distance from the central region CT of the porous main body 762 is increased in the longitudinal direction of the ultraviolet lamp 764, 762 may be constant with respect to the direction orthogonal to the longitudinal direction of the ultraviolet lamp 764. [

The size of the hole 766 formed in the porous main body 762 may be smaller in a direction perpendicular to the longitudinal direction of the ultraviolet lamp 764 in the central region CT of the porous main body 762, The length of the ultraviolet lamp 764 of the porous main body 762 may be constant.

The size of the hole 766 formed in the porous main body 762 is equal to the length of the ultraviolet lamp 764 in the central region CT of the porous main body 762 and the direction perpendicular to the longitudinal direction of the ultraviolet lamp 764 The smaller the distance becomes, the smaller it can become.

When the size of the holes 766 formed in the porous main body 762 is reduced as it moves from the central region CT of the porous main body 762 to the edge thereof, the holes 766 passing through the holes 766 of the porous main body 762 The flow rate of the air is most increased in the central region CT of the porous metal body 762 and the flow rate of the air passing through the hole 766 can be reduced as it moves to the edge region of the porous metal body 762.

Therefore, a large amount of air passes through the area where the sterilizing effect is strong, and a relatively small amount of air passes through the area where the sterilizing effect is weak. Therefore, the air sucked into the air conditioner is guided by the ultraviolet lamp 764 It is possible to sterilize it more effectively.

The ultraviolet sterilization module 760 according to the present embodiment may have a maximum through-hole area in the central region CT.

However, it is apparent that the size of the holes 766 formed in the porous main body 762 may vary depending on the shape and arrangement of the ultraviolet lamps 764, and the like. For example, the size of the hole 766 may become smaller toward the edge from the center of the porous main body 762.

FIG. 19 is a plan view for explaining an ultraviolet sterilizing module according to a fourth embodiment of the present invention, and FIG. 20 is a perspective view for explaining an ultraviolet sterilizing module according to a fourth embodiment of the present invention.

The holes 766 formed in the passage 763 of the porous main body 762 can face the gap between the adjacent ultraviolet lamps 764 among the plurality of ultraviolet lamps 764. [

More specifically, the holes 766 formed in the passage 763 of the porous main body 762 include a single ultraviolet lamp 764, which is one of the plurality of ultraviolet lamps 764 in the porous main body 762, May be formed in a part of a region corresponding to between one ultraviolet lamp (764) and another ultraviolet lamp (764) adjacent thereto.

Alternatively, the ultraviolet lamp 764 may be spaced apart from any one hole 766 of the plurality of holes 766 and another hole 766 adjacent to the one hole in a direction perpendicular to the longitudinal direction of the ultraviolet lamp .

Thus, air passing through the holes 766 of the porous main body 762 may not be disturbed by the ultraviolet lamp 764.

In addition, the ultraviolet lamp 764 may not be exposed on the front surface of the porous main body 762, thereby preventing the ultraviolet lamp 764 from being damaged due to an external impact.

When the user removes the front panel 710 of the air conditioner to check the inside of the air conditioner, when the ultraviolet lamp 764 is operating, ultraviolet rays emitted from the ultraviolet lamp 764 may cause injury to the user have.

At this time, the exposure of the ultraviolet rays through the hole 766 formed in the porous main body 762 can be reduced, so that the user can safely work.

21 is a plan view for explaining an ultraviolet sterilization module according to a fifth embodiment of the present invention.

The porous main body 762 included in the ultraviolet sterilization module 760 according to the present embodiment may be a metal lath formed by tearing a metal plate.

The rib 767 may be coupled to the holder mounting portion 765 by a separate adhesive or an engaging member and the rib 767 and the holder mounting portion 765 may be integrally formed. Alternatively, the end of the rib 767 may be engaged with a hole (not shown) formed in the inner surface of the holder mounting portion 765.

The holder mounting portion 765 may be formed on the upper and lower edges as well as the left and right edges of the porous main body 762. At this time, the holder 768 may not be mounted on the holder mounting portion 765 formed on the upper and lower edges of the porous main body 762. The holder mounting portions 765 formed at the upper and lower edges of the porous main body 762 may be narrower than the holder mounting portions 768 formed at the left and right edges.

In order to change the flow of air sucked into the air conditioner, the shape of the holder mounting portion 765 may be provided in the form of a free-form curve.

The shape of the hole 766 formed by the plurality of ribs 767 may be a polygonal shape in which the portion where one rib 767 and the other rib 767 are combined is rounded.

Each of the ribs 767 may have the same length.

The thickness of the rib 767 can be made narrow and the hole 766 can be formed in most areas of the passage 763. [ Thereby, the flow of air passing through the passage 763 of the porous main body 762 can be made more smooth.

22 is a plan view for explaining an ultraviolet sterilization module according to a sixth embodiment of the present invention.

The porous main body 762 included in the ultraviolet sterilization module 760 according to the present embodiment may be a climp mesh or a plain net.

The passage 763 of the porous main body 762 may be composed of a wire combination in which a plurality of wires 769 are cross-connected.

The wire 769 may be a metal material having elasticity.

The wire 769 may include a plurality of first wires 769a and a plurality of second wires 769b that are divided according to the shape of the bend or the orientation of the wire. Needless to say, it is possible to further include a separate type of wire, if necessary.

The plurality of first wires 769a are parallel to each other and can be spaced apart at regular intervals. The plurality of second wires 769b are parallel to each other and can be spaced apart at regular intervals.

The holes 766 may be formed in various shapes according to the coupling method of the first wire 769a and the second wire 769b.

  The first wire 769a and the second wire 769b may intersect vertically.

For example, the first wire 769a may be arranged in the left-right direction, and the second wire may be arranged in the up-down direction.

In addition, the first wire 769a and the second wire 769b may cross each other at an angle.

One first wire 769a of the plurality of first wires 769a may be arranged to abut the upper end of one second wire 769b of the plurality of second wires 769b. The other first wire 769a adjacent to the first wire 769a may be arranged to contact the lower end of the second wire. The other second wire 769b adjacent to the second wire 769b may be arranged to be in contact with the upper end of the first wire 769a. The other second wire 769b may be arranged to be in contact with the lower end of the other first wire 769a.

One wire 769 of the plurality of wires 769 may be formed with a valley (not shown) at a portion where the other wire 769 contacting the one wire 769 is in contact. The other wire 769 can be in contact with a valley formed on one wire 769.

However, the manner in which the wire is weaved is not limited thereto and may be woven in various ways. The shape of the holes 766 formed in the porous main body 762 may be polygonal. The longitudinal direction of the wire 769 may be a direction other than the longitudinal direction or the transverse direction.

The wire 769 may be coupled to the holder mounting portion 765.

23 is a cross-sectional view of an air conditioner including an ultraviolet sterilization module according to a seventh embodiment of the present invention.

The porous main body 762 included in the ultraviolet sterilization module 760 according to the present embodiment may include a bent portion 770 formed in a surface facing the heat exchanger 750. More specifically, the bending portion 770 may be convexly curved at a surface facing the ultraviolet lamp 764 with respect to one surface of the porous main body 762 facing the heat exchanger 750.

The bending portion 770 may be formed by bending the passage portion 763 and the holder mounting portion 765 at the same time.

The plurality of bending portions 770 may be formed parallel to each other.

The plurality of bending portions 770 may be separated from each other by a predetermined distance.

When the ultraviolet lamp 764 is disposed on both sides of the porous metal body 762, the direction in which the one bending portion 770, which is one of the plurality of bending portions 770, And may be opposite to the bent direction of the other bending portion 770.

In more detail, a plurality of ultraviolet lamps 764 disposed in parallel can be alternately arranged on one surface and the other surface of the porous main body 762. [ At this time, the bending portion 770 of the region corresponding to the ultraviolet lamp 764 disposed on one surface of the porous main body 762 can be bent so as to be convex in the other surface direction. Conversely, the bending portion 770 of the region corresponding to the ultraviolet lamp 764 disposed on the other surface of the porous main body 762 can be bent so as to be convex in one surface direction.

The porous main body 762 may be made of a metal material, so that the area can be deformed to be bent.

A hole 766 may also be formed in the bending portion 770.

The bending portion 770 may be formed in parallel with the ultraviolet lamp 764 and at least a part of the ultraviolet lamp 764 may be disposed in the concave space formed in the bending portion 770.

At both ends of the bending portion 770, a holder 768 for supporting the ultraviolet lamp 764 may be coupled. That is, the holder 768 may be coupled to a portion of the bending portion 770 where the holder mounting portion 765 is bent.

The bending portion 770 is formed in the porous main body 762 so that the extent to which the ultraviolet lamp 764 protrudes from the porous main body 762 can be reduced. Therefore, the risk of damage or breakage of the ultraviolet lamp 764 due to an external impact or the like can be reduced.

Also, when the porous main body 762 is installed at the same position in the air conditioner, the distance between the ultraviolet lamp 764 and the heat exchanger 750 may be increased when the bending portion 770 is formed.

Since heat is generated in the ultraviolet lamp 764, the heat exchange efficiency may be lowered if it is too close to the heat exchanger 750 that reduces the temperature of the air by exchanging the inhaled air with the refrigerant. At this time, since the bending portion 770 is formed in the porous metal body 762, the distance between the ultraviolet lamp 764 and the heat exchanger 750 is increased, and the heat exchange efficiency of the heat exchanger can be increased. In addition, since the mounting position of the porous main body 762 does not change, compactness can be maintained.

Meanwhile, at least one of the features of the ultraviolet sterilizing module 760 according to the first to seventh embodiments described above can be applied at the same time. For example, as the size and density of the holes 766 in the central region CT of the porous main body 762 are constant and the distance from the central region CT decreases, the density of holes 766 decreases, The size of the first electrode 766 may also be reduced.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.
