The 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 arranged so that the air inlet 712 is formed on the upper surface of the air conditioner, the air discharge port 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 become

In the main body 700, the air inlet 712 may be formed on the upper side of the air conditioner, particularly on the upper side of the air conditioner, and the air outlet 714 may be formed on the lower side of the air conditioner, especially on the lower side of the air conditioner. . In addition, it will be described that the front panel 710 forms the front appearance of the air conditioner and is rotated so as to protrude forward with the upper portion as the center for servicing the inside of the air conditioner.

In addition, the structures and functions 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 an embodiment of the present invention are shown in FIG. As described in FIG. 4, redundant description is 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 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 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 having a plurality of holes 766 formed therein, or may be composed of a wire combination in which a plurality of wires are intersectingly 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 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 supporting body, a porous lamp supporting body, a web main body, a mesh body, a web body, and the like.

A hole 766 through which air flows toward the UV lamp 764 may be formed in the porous main body 762 . Such a hole 766 may be formed with a certain size or larger to minimize flow resistance due to 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 main body 700 and the heat exchanger ( 750) may be located inside.

In the ultraviolet sterilization module 760, heat can be emitted from the ultraviolet 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 resistant to 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 UV lamp 764 and the heat exchanger 750 in the air flow direction. When the photocatalytic material is applied to the surface of the porous main body 762, the air can be deodorized by the porous main body 762 and then flowed to the UV 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 deodorizing components in the air to the surface of the UV lamp 764 can be minimized. Performance deterioration of the UV lamp 764 that may occur when the deodorizing component is excessively adsorbed on the surface of the UV lamp 764 may be minimized.

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), etc. may be included. The air sucked 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 is supplied to the heat exchanger 750. can be inhaled.

Meanwhile, even if the porous main body 762 is disposed in a space where gas flows, interference with the gas flow can be minimized. In addition, while the gas passes through the porous main body 762, it flows close to the UV lamp 764, so that the intensity of ultraviolet light transmitted to the gas or the range to which the ultraviolet light is irradiated may be increased. Accordingly, the sterilization power of the ultraviolet sterilization module 760 may be increased.

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

A plurality of UV lamps 764 may be disposed to be spaced apart from both sides of the porous main body 762 . All of the plurality of UV lamps 764 may be positioned 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 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 may primarily sterilize air passing between the air inlet 712 and the porous main body 762 . In addition, the UV lamp disposed between the porous main body 762 and the heat exchanger 750 may secondarily sterilize the air passing through the porous main body 762 .

As described above, the UV lamps may be distributed and disposed on the porous main body 762, and the photocatalytic material may be coated on the porous main body 762. As a result, air can be primarily sterilized between the air inlet 712 and the porous main body 762 . Furthermore, 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 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 UV lamp 764, and a pair of holders may support the UV lamp 764. The ultraviolet sterilization module 760 may include a plurality of pairs of holders. A plurality of pairs of holders may be arranged at regular intervals on 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 UV lamp 764 may be provided in the form of an external electrode having an external electrode. Accordingly, the first electrode may be provided on one side of the UV lamp 764 and the second electrode may be provided on the other side. Also, the first electrode and the second electrode may be provided by applying a conductive solder solution outside 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 applying 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, discharge is induced in the radiation material inside the ultraviolet lamp 764 by the electric field, and ultraviolet rays may be generated. According to this, since the first electrode and the second electrode are not in contact with the material sealed inside the UV lamp 764, the heat that may be generated from the UV lamp 764 is reduced, and the life of the UV lamp 764 is extended. can be increased

The power supply unit may supply power to the UV lamp 764 . Also, the power supply unit may stabilize the current supplied to the UV lamp 764 . In addition, the power supply unit may generate a high voltage required for generating ultraviolet rays in the ultraviolet lamp 764 . That is, the output frequency and driving voltage of the power supply unit may be changed and provided according to the driving frequency and driving voltage for driving the plurality of UV lamps 764 . For example, the power supply may be provided by an inverter, ballast, or the like.

A wire may connect the power supply unit and the plurality of UV lamps 764 . In detail, the wire may connect the first electrode and the second electrode and the power supply. In addition, the electric wire may connect the plurality of UV lamps 764 and the power supply unit in parallel. That is, by connecting the power supply unit and the plurality of UV lamps 764 in parallel, the plurality of UV lamps 764 may be simultaneously operated. In addition, even when one UV lamp 764 among the plurality of UV lamps 764 is defective, there is an advantage in that maintenance is easy.

On the other hand, although the UV lamp 764 according to an embodiment of the present invention is described as an external electrode fluorescent lamp method in which electrodes are provided on the outside, a method in which the electrodes are disposed inside the UV lamp will also be possible.

Hereinafter, the configuration of the ultraviolet lamp 764 will be described in detail. The UV lamp 764 of the external electrode fluorescent lamp type may be formed in a bar or tube shape in which an internal space is formed. And, the ultraviolet lamp 764 may be formed to be shielded to have a sealed inner space. The UV 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 light may be sealed in an 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 ultraviolet lamp 764 to generate ultraviolet rays.

For example, radiation materials in the ultraviolet lamp 764 include mercury (Hg), neon (Ne), xenon (Xe), krypton (Kr), argon (Ar), xenon bromide (XeBr), xenon chloride (XeCl), One or more of krypton bromide (KrBr), krypton chloride (KrCl), and methane (Ch4) may be included. Among the radiation materials 103, most of the materials other than mercury (Hg) may be provided in a gaseous state. In addition, the radiation materials may be sealed at a constant pressure in the inner space of the ultraviolet lamp 764. For example, the radiation material may be sealed in the inner space of the UV lamp 764 under normal or medium pressure. Meanwhile, the UV lamp 764 may be formed with a somewhat smaller diameter so as to 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.

When the ultraviolet lamp 764 is formed to have a diameter of 1 mm or less, there is a risk of breakage, and there is a problem in that it is difficult to charge the radiation material enclosed therein.

When the ultraviolet lamp 764 is formed to have a diameter of 7 mm or more, resistance to fluid flow may increase as the diameter increases. In addition, the voltage for discharging the radiation material charged in the UV lamp 764 is increased, and there is a problem in that 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 horizontal direction in the inner space of the air conditioner. Further, the thickness of the UV lamp 764 may be formed to a thickness capable of withstanding the pressure of the material sealed in the inner space of the UV lamp 764 . For example, the UV 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 UV lamp 764 may be provided outside both sides of the UV lamp 764 . Also, the first electrode and the second electrode may be formed by a conductive solder solution on both sides 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). For example, by putting both ends of an ultraviolet lamp 764 into a conductive solder solution, the conductive solder solution Electrodes may be formed at both ends of the UV lamp 764 by curing.

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

When the first electrode and the second electrode are formed smaller than 1 cm, there is a problem in that it is difficult to discharge the radiation material sealed inside the UV lamp 764 . That is, since the area provided with the first electrode and the second electrode is reduced, the efficiency of discharging the radiation material may be reduced.

When the first electrode and the second electrode are formed to be larger than 3 cm, the radiation material sealed inside 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 arranged in parallel on the porous main body 762 so that the air introduced through the air inlet 712 passes through the porous main body 762 to form a heat exchanger. When heading to (750), harmful substances can be sterilized.

The wavelength of ultraviolet rays generated by the ultraviolet lamp 764 may be a wavelength around 250 nm to 260 nm with high sterilizing power for microorganisms, and ultraviolet rays having a wavelength of 250 nm to 260 nm have a sterilizing effect 1000 to 10000 times greater than near ultraviolet rays. can

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

Meanwhile, the ultraviolet sterilization module 760 may 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 may be coupled to the rear surface of the front panel 710 of the air conditioner so that the UV lamp 764 faces the heat exchanger 750 .

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 UV 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 may be coupled to the rear surface of the filter frame so that the UV lamp 764 faces the heat exchanger 750 .

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

In FIG. 11, it is assumed that ultraviolet sterilization is performed using one conventional ultraviolet lamp 1000, and in FIG. 12, ultraviolet sterilization is performed by arranging 10 ultraviolet lamps 1100 in parallel according to an embodiment of the present invention. .

As shown in FIG. 11, when one conventional ultraviolet lamp 1000 is operated, the power energy measured in area A is 5mW/cm ² , the power energy measured in area B is 2.2mW/cm ² , and area C The power energy measured in is 0.6mW/cm ² and the power energy measured in the D region is 0.9mW/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 simultaneously, the narrower the distance due to the overlap effect, the higher the power density. Conversely, as the spacing increases, the effect of overlapping may decrease.

In fact, it is possible to consume less power when simultaneously operating 10 UV lamps 1100 of the present invention than operating one conventional UV lamp 1000 . Therefore, it is more efficient to use a plurality of UV lamps 1100 according to an embodiment of the present invention than to use conventional UV lamps in terms of power consumption, space efficiency, and UV sterilization effect.

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

Hereinafter, the same or similar parts as the previous description will be omitted and the 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, and a plurality of holes 766 provided in the porous main body 762. , may include a holder 768.

The porous main body 762 may be a conductor.

The UV lamp 764 of the external electrode fluorescent lamp type can emit high heat, and the porous main body 762 in which the UV lamp 764 is installed has durability due to deterioration due to the high heat emitted by the UV lamp 764. Problems can arise.

In addition, since the refrigerant exchanges heat with the air in the heat exchanger 750 inside the air conditioner, 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. That is, the porous main body 762 may be made of a metal material, preferably made of aluminum.

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

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

A plurality of holes 766 through which air passes and through which light emitted from the UV lamp is irradiated may be provided in the through part 763 .

A holder 768 may be mounted on the holder mounting portion 765 . Alternatively, the porous main body 762 may not include a separate holder mounting portion 765, and the holder 768 may be mounted on the through portion 763. Hereinafter, a case in which the holder mounting portion 765 is included in the porous main body 762 will be described as an example.

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

A holder 768 may be installed in the holder mounting portion 765 . The holder mounting portion 765 may be formed of metal, preferably aluminum (Al). Alternatively, the holder mounting portion 765 may be formed of an insulating material such as plastic to which current cannot be applied.

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

To stably support the holder 768 and the UV lamp 764, the thickness of the holder mounting portion 765 may be greater than that of the through portion 763.

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

Since the UV lamp 764 corresponding to the holder mounting portion 765 cannot irradiate ultraviolet rays toward the porous main body 762 due to the holder 768, the hole 766 may not be formed in the holder mounting portion 765. there is. Therefore, the manufacturing cost can be reduced when the holder mounting portion 765 is included in the porous main body 762 compared to the case where the entire porous main body 762 is manufactured with the through portion 763 .

Meanwhile, the UV lamp 764 may be disposed on one side of the porous main body 762 facing the heat exchanger 750 .

It is also possible that the porous main body 762 serves as the filter 80 without including the filter 80 and the filter frame 90 in the air conditioner.

The UV lamp 764 may be located on the opposite side of the filter 80 with the porous main body 762 as the center. The UV lamp 764 may also be disposed facing the filter 80 in the porous main body 762 .

The porous main body 762 may be formed to be longer than a second direction orthogonal to the first direction with respect to the first direction, which is the longitudinal direction of the UV lamp 764 . In more detail, when the ultraviolet lamp 764 is disposed in the horizontal direction with respect to the porous main body 762, the porous main body 762 may be formed longer in the horizontal direction than in the vertical direction.

Since air passing through the hole 766 formed in the through-hole 763 of the porous main body 762 can be sterilized by the ultraviolet lamp 764, the ultraviolet lamp 764 is disposed to face the through-hole 763. It can be. That is, the ultraviolet lamp 764 may be disposed to correspond to the through part 763 .

The UV 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, respectively. 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 unit such as an inverter through a wire. When a voltage is applied between the external electrodes 764a at both ends of the UV lamp 764 by the inverter and the wire, UV rays may be irradiated from the lamp body 764b. Ultraviolet rays irradiated from the lamp body 764b can sterilize air passing through the surface of the heat exchanger 750 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.

A plurality of ultraviolet lamps 764 may be arranged in parallel with a predetermined interval.

A plurality of UV lamps 764 may be arranged side by side with each other.

To prevent the UV lamp 764 from protruding to the side of the porous main body 762, the length of the porous main body 762 may be longer than that of the UV lamp 764.

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 disposed spaced apart from each other on one surface of the porous main body 762 .

The holder 768 may include a body portion 768a and a lamp coupling portion 768b extending from the body portion 768a to support the ultraviolet lamp 764 .

The body portion 768a may be installed on the holder mounting portion 765 of the porous main body 762, and the lamp coupling portion 768b may support the ultraviolet lamp 764.

Each holder 768 may support the UV lamp 764 so that the UV lamp 764 is spaced apart from the porous main body 762 . The ultraviolet lamp 764 may be supported by a pair of holders 768.

The porous main body 762 may be composed of a porous plate in which a plurality of holes 766 are formed. At this time, the porous main body 762 may be manufactured by drilling a hole in a plate to form a hole 766, and has an advantage in that the size and shape of the hole 766 can be determined relatively freely.

A plurality of holes 766 may be formed side by side in a horizontal direction and a vertical direction with respect to one surface of the porous main body 762 .

The sizes of the plurality of holes 766 may be the same or different.

The hole 766 may have any one of a circular shape, an elliptical shape, and a polygonal shape.

The air sucked into the air inlet is aligned while passing through the plurality of holes 766, thereby minimizing the concentration of the air as part of the plurality of ultraviolet lamps 764, and the plurality of ultraviolet lamps 764 circulating the air more evenly. can be sterilized.

In addition, since one porous main body 762 can protect a plurality of UV lamps 764 and support a plurality of UV lamps 764, the number of parts can be minimized.

In order to maximize the flow of air passing through the porous main body 762, the shape of the hole 766 may be a regular hexagonal honeycomb shape. Alternatively, the arrangement of the plurality of holes 766 may be the same as a honeycomb shape, but the shape of the hole 766 may be circular. At this time, since the area occupied by the hole 766 per unit area of the porous main body 762 may be maximized, the flow of air may be smooth.

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

Inside the main body 700, a filter 80 through which air sucked through the air inlet 712 is primarily filtered and a filter frame 90 supporting the filter 80 may be disposed. At this time, the filter 80 may be disposed on one surface of the filter frame 90, and the ultraviolet sterilization module 760 may be disposed on the other surface of the filter frame 90. Thus, the ultraviolet sterilization module 760 can be installed inside the main body 700 without additional additional components.

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, contents overlapping with those described above will be omitted, and description will focus on the differences.

Referring to FIGS. 15 and 16 , in the ultraviolet sterilization 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 through part 763 of the porous main body 762 may decrease as the distance from the central region CT of the porous main body 762 increases. In this case, the density of the holes 766 may mean the number of holes 766 per unit area of the through part 763 .

In the central region CT, the density of the holes 766 may be constant. The central region CT may include a center of the porous main body 762 and may have a predetermined area. The central region CT may have an elliptical shape having a long axis of the ultraviolet lamp 764 as a long axis.

When the area facing the UV lamp 764 in the porous main body 762 is the entire through portion 763, the central area CT may mean the central area of the through portion 763.

On the other hand, when the area facing the UV lamp 764 in the porous main body 762 is part of the through portion 763, the central region CT is located in a portion of the through portion 763 facing the ultraviolet lamp 764. It can mean the central area for

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 in the longitudinal direction of the ultraviolet lamp 764 increases, and the porous main body 762 ) may be constant in a direction orthogonal to the longitudinal direction of the UV lamp 764.

The density of the holes 766 formed in the porous main body 762 may decrease as the distance increases from the central region of the porous main body 762 in a direction perpendicular to the longitudinal direction of the ultraviolet lamp 764, and the porous main body ( The length direction of the UV lamp 764 of 762 may be constant.

The density of the holes 766 formed in the porous main body 762 is the longitudinal direction of the UV lamp 764 in the central region CT of the porous main body 762 and the direction orthogonal to the longitudinal direction of the UV lamp 764. It can decrease as you move away from it.

As described above, the ultraviolet sterilization module 760 includes a porous main body 762 in which a plurality of holes 766 are formed, and a plurality of ultraviolet lamps 764 coupled to the porous main body 762, and a plurality of The two ultraviolet lamps 764 may be arranged in parallel parallel to each other.

At this time, the sterilization effect by the ultraviolet lamp 764 may be weakened from the central region CT of the porous main body 762 to the edge.

The sterilization effect of ultraviolet rays is weakened as the distance from the ultraviolet lamp 764, which is the light source, is weakened. As the plurality of ultraviolet lamps 764 are overlapped, this decrease in the sterilization effect can be compensated for. In the central region CT of the porous main body 762, this overlapping effect may be constantly maintained. However, as the distance from the central region CT of the porous main body 762 increases, such an overlapping effect decreases, and thus the sterilization effect by the ultraviolet lamp 764 may be weakened. This can also be confirmed by the numerical values shown in FIG. 12 .

When the density of the holes 766 formed in the porous main body 762 decreases as it moves from the central region CT of the porous main body 762 to the edge, the hole passing through the hole 766 of the porous main body 762 The flow rate of air is greatest in the central region CT of the porous main body 762, and the flow rate of air passing through the hole 766 may decrease as it moves toward the edge region of the porous main body 762.

Therefore, since a large flow rate of air passes through an area with a strong sterilization effect and a relatively low flow rate of air passes through an area with a weak sterilization effect, the air sucked into the air conditioner is removed by the ultraviolet lamp 764. It can be sterilized more effectively.

When the porous main body 762 has a shape bent at least once, the porous main body 762 may have at least two or more flat surfaces. At this time, each plane constituting 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 area in the central region CT. In this case, the central region CT may mean a region in which the sterilization effect by the ultraviolet lamp 764 is maximized. Accordingly, if the arrangement of the ultraviolet lamps 764 is changed, the number and size of the central region CT may be changed.

Accordingly, it is obvious that the density of the holes 766 formed in the porous metal body 762 may vary depending on the shape or arrangement of the UV lamps 764. For example, the density of the holes 766 may decrease from a central point to an edge of the porous metal body 762 .

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

Since the ultraviolet sterilization module 760 according to the third embodiment is identical to the ultraviolet sterilization module 760 according to the second embodiment and the central region CT, overlapping descriptions will be omitted and differences will be mainly described.

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

The size of the hole 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. For example, when the hole 766 has a circular shape, the diameter of the hole 766 may decrease as the distance from the central region CT of the porous metal body 762 increases.

The size of the hole 766 may be constant in the central region CT.

The size of the hole 766 formed in the porous main body 762 may decrease as it moves away from the central region CT of the porous main body 762 in the longitudinal direction of the ultraviolet lamp 764, and the porous main body ( A direction orthogonal to the longitudinal direction of the UV lamp 764 of 762 may be constant.

The size of the hole 766 formed in the porous main body 762 may decrease as it moves away from the central region CT of the porous main body 762 in a direction perpendicular to the longitudinal direction of the ultraviolet lamp 764, The longitudinal direction of the UV 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 the longitudinal direction of the UV lamp 764 in the central region CT of the porous main body 762 and the direction orthogonal to the longitudinal direction of the UV lamp 764. The farther you go, the smaller it can be.

When the size of the hole 766 formed in the porous main body 762 decreases as it moves from the central region CT of the porous main body 762 to the edge, the hole passing through the hole 766 of the porous main body 762 The flow rate of air is greatest in the central region CT of the porous metal body 762, and the flow rate of air passing through the hole 766 may decrease as it moves toward the edge region of the porous metal body 762.

Therefore, since a large flow rate of air passes through an area with a strong sterilization effect and a relatively low flow rate of air passes through an area with a weak sterilization effect, the air sucked into the air conditioner is removed by the ultraviolet lamp 764. It can be sterilized more effectively.

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

However, it is obvious that the size of the hole 766 formed in the porous main body 762 may vary depending on the shape or arrangement of the UV lamp 764. For example, the size of the hole 766 may decrease from the center to the edge of the porous main body 762 .

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

The hole 766 formed in the through portion 763 of the porous main body 762 may face a gap between adjacent UV lamps 764 among the plurality of UV lamps 764 .

In more detail, the hole 766 formed in the through-hole 763 of the porous main body 762 connects one UV lamp 764, which is any one of the plurality of UV lamps 764, to the porous main body 762 and the plurality of UV lamps 764. It may be formed in a portion of a corresponding region between one UV lamp 764 and another adjacent UV lamp 764 .

Alternatively, the ultraviolet lamp 764 looks at a distance between one hole 766 of the plurality of holes 766 and another hole 766 adjacent to the one hole in a direction orthogonal to the longitudinal direction of the ultraviolet lamp. Can be placed for viewing.

Accordingly, the flow of air passing through the hole 766 of the porous main body 762 may not be hindered by the UV lamp 764 .

Also, since the UV lamp 764 may not be exposed to the front surface of the porous main body 762 , damage to the UV lamp 764 due to external impact may be prevented.

When the user removes the front panel 710 of the air conditioner to inspect the inside of the air conditioner, if the UV lamp 764 is operating, the ultraviolet rays emitted from the UV lamp 764 may injure the user. there is.

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

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 and stretching a metal plate.

The through part 763 of the porous main body 762 may be formed by combining a plurality of ribs 767 . The plurality of ribs 767 may be integrally formed.

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

The holder mounting portion 765 may be formed on upper and lower edges as well as left and right edges of the porous main body 762 . In this case, 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 . In addition, the holder mounting portion 765 formed on the upper and lower edges of the porous main body 762 may have a narrower width than the holder mounting portion 768 formed on 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 shape of a free curve.

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

Each rib 767 may be the same length.

Since the thickness of the rib 767 may be thin, a hole 766 may be formed in most of the through portion 763 . Thus, the flow of air passing through the through part 763 of the porous main body 762 can be more smoothly.

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 crimp mesh or a plain weave mesh.

The through part 763 of the porous main body 762 may be composed of a wire combination in which a plurality of wires 769 are crossed.

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 classified according to a bending shape or an arrangement direction. Needless to say, a separate type of wire may be further included.

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

The hole 766 may be formed in various shapes depending on how the first wire 769a and the second wire 769b are coupled.

The first wire 769a and the second wire 769b may cross each other vertically.

For example, the first wire 769a may be disposed in a left-right direction, and the second wire may be disposed in a vertical direction.

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

Among the plurality of first wires 769a, one first wire 769a may be disposed to be in contact with an upper end of one second wire 769b among the plurality of second wires 769b. Another first wire 769a adjacent to the one first wire 769a may be disposed to be in contact with a lower end of the one second wire. In addition, another second wire 769b adjacent to the one second wire 769b may be disposed to be in contact with an upper end of the one first wire 769a. The rudder second wire 769b may be disposed to be in contact with the lower end of the rudder first wire 769a.

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

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

A 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 recessed on a surface facing the heat exchanger 750 . In more detail, with respect to one side of the porous main body 762 facing the heat exchanger 750, the bending unit 770 may be bent such that an area facing the UV lamp 764 is concave and the other side is convex.

The bending portion 770 may be formed by simultaneously bending the through portion 763 and the holder mounting portion 765 .

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

Each of the plurality of bending parts 770 may be spaced apart by a predetermined distance.

When the ultraviolet lamps 764 are disposed on both sides of the porous metal body 762, the direction in which one of the plurality of bending parts 770 is bent is adjacent to the bending part 770. It may be opposite to the bending direction of the other bending part 770 .

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

Since the porous main body 762 may be made of a metal material, the region may be deformed to be bent.

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

The bending portion 770 may be formed parallel to the UV lamp 764, and at least a portion of the UV lamp 764 may be disposed in a concave space formed in the bending portion 770.

Holders 768 supporting the UV lamp 764 may be coupled to both ends of the bending portion 770 . That is, the holder 768 may be coupled to a portion of the bending portion 770 in which the holder mounting portion 765 is bent.

Since the bending portion 770 is formed in the porous main body 762, the degree of protrusion of the UV lamp 764 from the porous main body 762 may be reduced. Accordingly, the risk of damage or breakage of the UV lamp 764 by an external impact light may be reduced.

In addition, when the porous main body 762 is installed at the same location in the air conditioner, the distance between the UV lamp 764 and the heat exchanger 750 may increase when the bending portion 770 is formed.

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

Meanwhile, at least one or more of the characteristics of the ultraviolet sterilization module 760 according to the first to seventh embodiments described above may be simultaneously applied. For example, the size and density of the holes 766 are constant within the central region CT of the porous main body 762, and the density of the holes 766 decreases as the distance from the central region CT increases. The size of (766) may also be reduced.

The above description is merely an example of the technical idea of the present invention, and various modifications and variations can be made to those skilled in the art without departing from the essential characteristics of the present invention.
