1A and 1B are views showing an air conditioning system 10 according to an embodiment of the present application. Specifically, FIG. 1A is a block diagram briefly showing an air conditioning system 10 according to an embodiment of the present application. FIG. 1B is a more detailed view of the sterilization apparatus 100 and the evaporator 12_2 of FIG. 1A.

Referring to Figs. 1A and 1B, an air conditioning system 10 includes an outdoor unit 11 and an indoor unit 12. The outdoor unit 11 includes a compressor 11_1 and a condenser 11_2 and the indoor unit 12 includes a light source module 100 installed in an expansion valve 12_1, an evaporator 12_2 and an evaporator 12_2.

Referring to the configuration of the outdoor unit 11, the compressor 11_1 sucks the low-temperature low-pressure gas refrigerant evaporated in the evaporator 12_2. Then, the compressor 11_1 increases the pressure of the gas refrigerant and releases the gas refrigerant whose pressure has increased.

The condenser 11_2 discharges heat of the gas refrigerant by performing heat exchange between the high temperature and high pressure gas refrigerant discharged from the compressor 120 to the surrounding air and the cooling water. At this time, the gaseous refrigerant emits heat and is condensed and liquefied. The air heated by the heat released in this process is discharged to the outside through a blower (not shown). The liquefied refrigerant flows into the indoor unit (12).

Referring to the configuration of the indoor unit 12, the expansion valve 12_1 serves to lower the pressure of the liquefied refrigerant. That is, the expansion valve 12_1 lowers the pressure of the liquefied refrigerant so that evaporation easily occurs in the evaporator 12_2.

The evaporator 12_2 vaporizes the low-temperature low-pressure liquid refrigerant that has passed through the expansion valve 12_1, and the vaporized refrigerant exchanges heat with the air in the room. Subsequently, the heat exchanged gaseous refrigerant moves to the compressor 11_1. Through the repetition of the circulation process of the refrigerant, the refrigerant evaporated in the evaporator 12_2 serves to lower the indoor air.

In one embodiment according to the technical idea of the present application, the light source module 100 is provided in the evaporator 12_2. The light source module 100 irradiates the ultraviolet ray having a wavelength having a sterilizing effect to the evaporator 12_2, thereby sterilizing the bacteria or fungi around the evaporator 12_2.

More specifically, as shown in FIG. 1B, the evaporator 12_2 generally has a shape in which a plurality of heat exchange plates are arranged side by side at small intervals. For example, the spacing between the plates for heat exchange may be 1-2 mm in the case of a small air conditioner. As described above, since the interval between the plates for heat exchange of the evaporator 12_2 is considerably narrow, the surface tension of the water droplet keeps the water droplets in the state of being kept in place without flowing down in the gravity direction, Mold, etc. may breed.

In order to perform the sterilization operation for such bacteria or fungi, the light source module 100 according to the embodiment of the present application performs a sterilization operation for the evaporator 12_2. Particularly, the light source module 100 is installed in the evaporator 12_2 so as to irradiate the ultraviolet rays toward the spacing space between the plurality of heat exchange plates and simultaneously occupy a minimum space. For example, the light source module 100 includes a fastening portion extending in a direction perpendicular to the substrate on which the light source is mounted, and the fastening portion is inserted and coupled to the gap between the plurality of heat exchange plates, 100 may be installed in the evaporator 12_2.

As described above, the air conditioning system 10 according to the embodiment of the present application includes the light source module 100 for performing the sterilizing operation on the evaporator 12_2, and the light source module 100 is connected to the evaporator 12_2 And is irradiated with ultraviolet rays toward a spacing space between a plurality of heat exchange plates. Therefore, the air conditioning system 10 according to the embodiment of the present application can sterilize bacteria, fungi, and the like propagated in the evaporator 12_2. In addition, since the light source module 100 according to the embodiment of the present application is installed closely to the evaporator 12_2, it is possible to maintain the sterilizing power at the maximum, and at the same time, a separate space for installation of the light source module 100 is not required, There are advantages.

It is to be understood that the above description is illustrative and that the technical idea of the present application can be variously applied and applied. In the following, various applications and applications of the present application will be described in more detail with reference to the drawings.

The air inlet (22) provides a passage for allowing the indoor air to flow into the air conditioner (20). The air introduced into the air conditioner 20 through the air inlet 22 is supplied to the evaporator 23. The evaporator 23 performs a heat exchange operation with respect to air introduced into the evaporator 23. That is, the introduced air transfers heat to the refrigerant vaporized in the evaporator 23, and as a result, the temperature of the introduced air is lowered. The low-temperature air is guided to the air outlet 25 by the air circulator 24, and is discharged to the room again through the air outlet 25. [

However, the upper housing 211 and the lower housing 212 may be combined through various coupling methods such as a screw coupling method, a fitting coupling method, and a screw coupling method.

The housing 210 may be made of various materials. The housing 210 may be made of a polymer resin, but is not limited thereto. The housing 210 may be made of another material having durability as long as it can accommodate the light source 210 and the substrate 220. The housing 210 may be made of a metal material such as aluminum, stainless steel or the like. Further, the housing 210 may be made of one material or two or more materials. For example, the lower housing 210 may be made of a metal such as aluminum, and the upper housing 210 may be made of a polymer resin or the like.

The fastening portion 220 is formed on the lower surface of the housing 210, particularly, the lower housing 212.

However, the shape, shape, number and the like of the fastening portion 220 are not particularly limited as long as they can be fastened between the plurality of heat exchange plates of the evaporator 23.

The light source 230 is mounted on the substrate 240 and emits ultraviolet rays. For example, the light source 230 may emit ultraviolet rays having a sterilizing effect toward the evaporator 23. For example, the light source 230 may be a light emitting diode chip that emits ultraviolet rays having a wavelength range of 200 nm to 280 nm, which is a UVC region. However, this is an example, and if the emitting ultraviolet ray has a sterilizing effect, the kind and the emission wavelength of the light source 230 are not limited.

The light source 230 may be mounted on the substrate 240 in the form of a metal can or a lead-out lead frame package that can be surface-mounted, or may be installed in a form capable of through-hole mounting. In addition, the light source 230 may be mounted on a bare chip or a flip chip type to form a chip on-board (COB) package, and an intermediate substrate Or may be installed in a form attached to a sub-mount.

The substrate 240 extends in one direction, and a light source 230 is mounted on the entire surface.

For example, the number of the first reinforcing member 211a and the second reinforcing member 211b formed in the upper housing 211 can be appropriately adjusted according to the size of the light source module 200_1. For example, the larger the upper housing 211, the more the first reinforcing member 211a and the second reinforcing member can be provided, and thus the structural rigidity of the upper housing 211 can be assured.

Meanwhile, the first reinforcing member 211a and the second reinforcing member 211b may have a step corresponding to the shape of the substrate 240, as shown in FIG. 4B.

For example, as shown in FIG. 4C, the substrate 240 includes first and second reinforcing members 211a and 211b formed on the upper housing 211, and an opening side wall 212h formed on the lower housing 212 Lt; / RTI > In this case, the substrate 240 is seated so as to fit the step formed on the first reinforcing member 211a and the second reinforcing member 211, so that it can be fixed without shaking in the lateral direction.

The transparent portion 250 is provided on the lower housing 212 and transmits light emitted from the light source 230. For example, as shown in Fig. 4C, the transparent portion 250 may be provided so as to be seated on the opening upper surface 212e and cover the opening portion. In this case, since the transparent portion 250 is disposed outside the housing 210, not the inside of the housing 210, a structure for supporting the transparent portion 250 is not formed inside the housing 210. The longitudinal size of the lower housing 212 can be reduced. As the vertical size of the lower housing 212 becomes smaller, the distance between the evaporator 23 and the light source 230 to be sterilized is shortened, so that the sterilizing power of the light source module 200_1 can be increased .

The adhesive member 251 bonds the transparent portion 250 and the lower housing 212 together. For example, the adhesive member 251 may be provided on the upper surface 212e of the opening portion to adhere the upper surface 212e of the opening portion to the transparent portion 250. [ In this case, the adhesive member 251 may be provided in a shape corresponding to the opening upper surface 212e. For example, as shown in FIG. 4B, when the opening upper surface 212e is in the form of a square ring, the adhesive member 251 may also be provided in a corresponding rectangular ring shape.

The adhesive member 251 may seal the transparent portion 250 and the lower housing 212 to provide a waterproof function to the light source module 200. Accordingly, it is possible to prevent water or moisture from penetrating between the transparent portion 250 and the lower housing 212.

The adhesive member 251 may be formed of an acrylic resin, an acrylic resin anaerobic, an acrylic emulsion, a polyurethane resin, a urethane resin emulsion, a polyurethane resin hot melt Polyurethane Hot Melt (TPU), Reactive Hot Melt Adhesive (R-HM), Ethercellulose, Ethylene-Vinylacetate copolymer emulsion, Ethylene-Vinylacetate copolymer Hot melt Epoxy resin, Epoxy emulsion, Polyvinyl Chloride solvent type, Polychloroprene rubber, α-cyanoacrylate, Silicone adhesives (Silicone adhesives), Silicone adhesives ), Modified silicone adhesive (Modified Silicone adhesives), and the like.

5 is a sectional view showing a light source module 200_2 according to another embodiment of the present application.

The light source module 200_2 of FIG. 5 is similar to the light source module 200_1 of FIG. Accordingly, the same or similar components are denoted by the same or similar reference numerals, and redundant descriptions will be omitted below for the sake of brevity.

Compared to the light source module 200_1 of FIG. 4, the light source module 200_2 of FIG. 5 has a transparent portion 250 of a smaller size. The transparent portion 250 of the light source module 200_2 of FIG. 5 is disposed closer to the light source 230 than the light source module 200_1 of FIG.

More specifically, the opening upper surface 212e on which the transparent portion 250 is mounted is formed at an end of the opening side wall 212h in the direction of the light source 230. The transparent part 250 is arranged adjacent to the light source 230 and the substrate 240 on which the light source 230 is mounted and the transparent part 250 are separated from each other by the opening upper surface 212e. In this case, since the distance between the transparent portion 250 and the light source 230 is close, the light emitted from the light source 230 can be irradiated to the outside without loss.

Since the upper surface 212e of the opening portion of FIG. 5 where the transparent portion 250 is seated is smaller than the upper surface of the opening portion of FIG. 4, the size of the transparent portion 250 provided on the upper surface 212e of the opening portion of FIG. Is smaller than the transparent portion in Fig. Accordingly, the possibility that water or moisture penetrates between the transparent portion 250 and the lower housing 212 is reduced, and the waterproof performance of the light source module 200_2 can be improved.

4, the vertical size of the lower housing 212 of the light source module 200_2 of FIG. 5 may be small, so that the evaporator 23 and the light source 230, which are to be sterilized, The sterilizing power of the light source module 200_2 can be improved.

6 is a sectional view showing a light source module 200_3 according to another embodiment of the present application.

The light source module 200_3 of FIG. 6 is similar to the light source modules 200_1 and 200_2 of FIGS. Accordingly, the same or similar components are denoted by the same or similar reference numerals, and redundant descriptions will be omitted below for the sake of brevity.

Unlike the light source modules 200_1 and 200_2 of FIGS. 4 and 5, the transparent portion 250 of the light source module 200_3 of FIG. 6 is provided inside the housing 210. FIG. Specifically, the transparent part 250 is provided between the upper housing 211 and the lower housing 212, and the light source module 200_3 includes the transparent part 250 between the upper housing 211 and the lower housing 212 And may further include a supporting portion 214 and a pressing member 217 for fixing.

The supporting portion 214 can fix the substrate 240 together with the first reinforcing member 211a. For example, the support portion 214 may be integrally provided with the lower housing 212, and may be formed to extend in the longitudinal direction. The supporting portion 214 may have a bridge shape for example and the electric wire connected to the connectors 260a and 260b through the opening formed in the bridging support portion 214 is inserted through the through holes 215 and 215 ' And can be taken out of the module 200_3.

The pressing member 217 fixes the substrate 240 and the transparent portion 250. For example, the pressing member 217 can fix the substrate together with the first reinforcing member 211a and the supporting portion 214, and at the same time, fix the transparent portion 250 together with the opening side wall 212h. For example, the pressing member 217 may be formed using an elastic member such as a rubber ring, but is not limited thereto.

By including the supporting portion 214 and the pressing member 217, the structural stability and rigidity of the light source module 200 can be improved. Also, since the transparent portion 250 is provided inside the housing 210, the possibility that the transparent portion 250 is broken due to an external impact may be reduced.

In addition, as compared with the light source modules 200_1 and 200_2 of FIGS. 4 and 5, the light source module 200_3 of FIG. 6 further includes a longitudinally extending pressing member 217, The distance between the evaporator 23 and the light source 230 may be as long as the longitudinal length of the pressing member 217. [ As a result, by increasing the distance between the sterilizing object and the light source 230, a sterilizing operation for a wider area can be performed.

7 is a sectional view showing a light source module 200_4 according to another embodiment of the present application.

The light source module 200_4 of FIG. 7 is similar to the light source modules 200_1, 200_2, and 200_3 of FIGS. Accordingly, the same or similar components are denoted by the same or similar reference numerals, and redundant descriptions will be omitted below for the sake of brevity.

7, the transparent part 250 is provided outside the housing 210, and may be fixed to the opening side wall 212h in a hook-like manner.

More specifically, the opening sidewall 212h may be composed of an opening sidewall upper end 2121 and an opening sidewall lower end 2122. The opening sidewall upper end 2121 and the opening sidewall lower end 2122 may be formed in the form of a clamp or a hook.

An opening sidewall bottom end 2122 is provided between the substrate 240 and the transparent portion 250. The lower side wall 2122 of the opening part fixes the substrate 240 together with the first reinforcing member 211a and fixes the transparent part 250 together with the upper side wall 2121 of the opening part.

The upper side wall 2121 of the opening portion fixes the transparent portion 250 together with the lower side wall 2122 of the opening portion. The upper portion 2121 of the opening side wall can be formed using a soft material so that the transparent portion 250 can be easily fitted between the upper portion 2121 of the opening side wall and the lower portion 2122 of the opening side wall without any equipment . In this case, since the hook-shaped opening side wall 212h fixes the transparent portion 250 firmly, the transparent portion 250 can be fixed on the housing 210 without the adhesive member. Therefore, the manufacturing process of the light source module 200_4 can be simplified, and the manufacturing cost of the light source module 200_4 can be reduced.

The opening sidewall upper end 2121 may be formed to have the same or similar inclination as that of the light source 230. Therefore, the ultraviolet rays emitted from the light source 230 can be irradiated to the outside of the light source module 200_4 without being obstructed by the upper end 2121 of the side wall of the opening portion, and as a result, the sterilizing power can be improved.

8A illustrates a cross-section of a light source 230 according to one embodiment of the present application, and FIG. 8B illustrates a cross-sectional view taken along the perforated line A-B-B'-A 'of FIG. 8A. 8A and 8B, a light source 230 according to an embodiment of the present invention includes a first conductivity type semiconductor layer 1111, a mesa structure including an active layer 1112 and a second conductivity type semiconductor layer 1113, And may further include a growth substrate 1100 and a second electrode 1120. The growth substrate 1100 may include a first insulating layer M, a first insulating layer 1130, a first electrode 1140, and a second insulating layer 1150, .

The growth substrate 1100 is not limited as long as it can grow the first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113. For example, the growth substrate 1100 may be a sapphire substrate, A carbide substrate, a gallium nitride substrate, an aluminum nitride substrate, a silicon substrate, or the like. The side surface of the growth substrate 1100 may include an inclined surface, so that the extraction of the light generated in the active layer 1112 can be improved.

The second conductivity type semiconductor layer 1113 may be disposed on the first conductivity type semiconductor layer 1111 and the active layer 1112 may include a first conductivity type semiconductor layer 1111 and a second conductivity type semiconductor layer 1113, As shown in FIG. The first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113 may include a III-V compound semiconductor, for example, (Al, Ga, In) N Based semiconductor, for example. The first conductivity type semiconductor layer 1111 may include an n-type impurity (for example, Si), and the second conductivity type semiconductor layer 1113 may include a p-type impurity (for example, Mg) have. It may also be the opposite. The active layer 1112 may comprise a multiple quantum well structure (MQM). When a forward bias is applied to the light source 230, electrons and holes are combined with each other in the active layer 1112 to emit light. The first conductivity type semiconductor layer 1111, the active layer 1112 and the second conductivity type semiconductor layer 1113 may be formed on a growth substrate (not shown) using techniques such as metal organic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) 1100). ≪ / RTI >

The light source 230 may include at least one mesa M including an active layer 1112 and a second conductivity type semiconductor layer 1113. The mesa M may include a plurality of protrusions, and the plurality of protrusions may be spaced from each other. The present invention is not limited thereto, and the light source 230 may include a plurality of mesas M spaced from each other. The side surface of the mesa M may be inclined by using a technique such as photoresist reflow and the side surface of the inclined mesa M may improve the luminous efficiency generated in the active layer 112. [

The first conductivity type semiconductor layer 1111 may include a first contact region R 1 and a second contact region R 2 exposed through the mesa M. [ Since the mesa M is formed by removing the active layer 1112 and the second conductivity type semiconductor layer 1113 disposed on the first conductivity type semiconductor layer 1111, Type semiconductor layer 1111 is exposed. The first electrode 1140 may be electrically connected to the first conductivity type semiconductor layer 1111 by making contact with the first contact region Rl and the second contact region R2. The first contact region R1 may be disposed around the mesa M along the periphery of the first conductivity type semiconductor layer 1111 and specifically between the mesa M and the side of the light source 230, And may be disposed along the upper surface of the conductive semiconductor layer. The second contact region R2 may be at least partially surrounded by the mesa M. [

The length of the second contact region R2 in the major axis direction may be 0.5 times or more the length of one side of the light source 230. [ In this case, since the region where the first electrode 1140 and the first conductivity type semiconductor layer 1111 are in contact with each other can be increased, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 can be more effectively So that the forward voltage can be further reduced.

The second electrode 1120 is disposed on the second conductivity type semiconductor layer 1113 and can be electrically connected to the second conductivity type semiconductor layer 1113. The second electrode 1120 is formed on the mesa M and may have the same shape according to the shape of the mesa M. [ The second electrode 1120 includes a reflective metal layer 1121 and may further include a barrier metal layer 1122 and the barrier metal layer 1122 may cover the top and sides of the reflective metal layer 1121. The barrier metal layer 1122 may be formed to cover the upper surface and the side surface of the reflective metal layer 1121 by forming a pattern of the reflective metal layer 1121 and forming the barrier metal layer 1122 thereon. For example, reflective metal layer 1121 may be formed by depositing and patterning Ag, Ag alloy, Ni / Ag, NiZn / Ag, and TiO / Ag layers.

The barrier metal layer 1122 may be formed of Ni, Cr, Ti, Pt, Au or a composite layer thereof. Specifically, the barrier metal layer 1122 may be formed of Ni / Ag / [Ni / Ti] 2 / Au / Ti. More specifically, at least a part of the upper surface of the second electrode 1120 may include a Ti layer having a thickness of 300 ANGSTROM. The bonding strength between the first insulating layer 1130 and the second electrode 1120 is improved and the reliability of the light source 230 is improved Can be improved.

The electrode protection layer 1160 may be disposed on the second electrode 1120 and the electrode protection layer 1160 may be formed of the same material as the first electrode 1140 but is not limited thereto.

The first insulating layer 1130 may be disposed between the first electrode 1140 and the mesa M. The first electrode 1140 and the mesa M may be insulated through the first insulating layer 1130 and the first electrode 1140 and the second electrode 1120 may be insulated. The first insulating layer 1130 may partially expose the first contact region Rl and the second contact region R2. The first insulating layer 1130 may expose a portion of the second contact region R2 through the opening 1130a and the first insulating layer 1130 may expose a portion of the first conductive semiconductor layer 1111 At least a part of the first contact region R1 may be exposed, covering only a part of the first contact region R1 between the outer periphery and the mesa M.

The first insulating layer 1130 may be disposed on the second contact region R2 along the outline of the second contact region R2. At the same time, the first insulating layer 1130 may be disposed adjacent to the mesa M rather than a region where the first contact region R 1 and the first electrode 1140 are in contact with each other.

The first insulating layer 1130 may have an opening 1130b for exposing the second electrode 1120. [ The second electrode 1120 can be electrically connected to the pad or the bump through the opening 1130b.

A region where the first contact region R 1 and the first electrode 140 are in contact is disposed along the entire outer periphery of the upper surface of the first conductivity type semiconductor layer. The first contact region R 1 and the first electrode 1140 may be arranged so as to be adjacent to all four sides of the first conductivity type semiconductor layer 1111 and completely surround the mesa M, . In this case, since the region where the first electrode 1140 and the first conductivity type semiconductor layer 1111 are in contact with each other can be increased, the current flowing from the first electrode 1140 to the first conductivity type semiconductor layer 1111 can be more effectively So that the forward voltage can be further reduced.

In one embodiment of the present application, the first electrode 1140 and the second electrode 1120 of the light source 230 may be mounted on the substrate 240 directly or through a pad.

For example, when the light source 230 is mounted on the substrate 240 through a pad, two pads disposed between the light source 230 and the substrate 240 may be provided, The first electrode 1140 and the second electrode 1120 can be in contact with each other. For example, the pad may be solder or eutectic metal, but is not limited thereto. For example, AuSn may be used as the eutectic metal.

Alternatively, when the light source 230 is directly mounted on the substrate 240, the first electrode 1140 and the second electrode 1120 of the light source 230 may be directly bonded to the wiring on the substrate 240. In this case, the bonding material may include an adhesive material having a conductive property. For example, the bonding material may include at least one of silver (Ag), tin (Sn), and copper (Cu). However, this is merely an example, and the bonding material may include various materials having conductivity.

As described above, the growth substrate 1100 of the light source 230 of the present application is disposed so as to be positioned in the direction opposite to the substrate 240. [ That is, the light source 230 according to the embodiment of the present invention may be implemented in the form of a flip chip.

FIG. 9 is a view schematically showing how the light source modules 200, 200_1 to 200_4 of FIGS. 3 to 7 are installed in the evaporator 23. FIG.

9, fastening portions 221_2 and 222_2 extending in a direction perpendicular to the substrate 240 are formed on the lower surface of the lower housing 212. The fastening portions 221_2 and 222_2 are connected to the evaporator 23 The heat exchanger plate is inserted and fixed in the spacing space between the plurality of heat exchange plates included in the heat exchanger plate. In this case, the fastening portions 221_2 and 222_2 and the plurality of heat exchange plates may be arranged parallel to each other, thereby increasing the contact area, and thus the light source module 200 may be stably fixed to the evaporator 23 have.

When power is supplied from the outside in a state where the light source modules 200 and 200_1 to 200_4 are fixed to the evaporator 23, the sterilizing operation of the light source modules 200 and 200_1 to 200_4 is performed. That is, the electric wire 1 can be drawn out to the outside through the through hole 215 formed in the upper housing 211, and external power can be supplied to the light source module 200 through the electric wire 1. In this case, ultraviolet rays are emitted from the light source 230 of the light source modules 200 and 200_1 to 200_4, and the ultraviolet rays are supplied to the evaporator 23 through the transparent part 250. [

In this case, the sterilizing area A to be sterilized by ultraviolet rays may be different depending on the directivity angle of the light source 230. For example, if the light source 230 has an orientation angle Q of a certain angle, the sterilization zone A may be proportional to the orientation angle Q.

In one embodiment of the present invention, the growth substrate 1100 of the light source 230 may be mounted to be positioned opposite to the substrate 240, as described above with reference to FIGS. 8A and 8B. That is, the light source 230 may be mounted on the substrate 240 in the form of a flip chip. In this case, since the ultraviolet light is emitted through the growth substrate 1100, the directivity angle of the ultraviolet light emitted from the light source 230 may be larger than that of a general light source. As a result, the light source 230 according to the exemplary embodiment of the present invention may have a larger directivity angle as compared with the general case, and thus the sterilizing area A of the evaporator 23 may be wider.

10 is a sectional view showing a light source module 200 'according to another embodiment of the present application. The light source module 200 'of FIG. 10 is similar to the light source module 200 of FIGS. Accordingly, the same or similar components are denoted by the same or similar reference numerals, and the repeated description will be omitted below for the sake of brevity.

The light source module 200 'of FIG. 10 is implemented to have a wider sterilizing area B than the light source modules 200, 200_1 to 200_4 of FIGS. To this end, the light source module 200 'of FIG. 10 may be implemented such that the distance d1 between the light source 230 and the transparent portion 250 is minimized. Further, a spacer 216 may be provided to define a predetermined distance d2 between the lower housing 212 and the evaporator 23. [

The light source module 200 'of FIG. 10 may be implemented such that the distance d1 between the light source 230 and the transparent portion 250 is minimized. In this case, the length of the support portion 214 'in the direction perpendicular to the substrate 240 may be shorter than that in FIG.

More specifically, the directivity angle (Q, see FIG. 9) of the light source generally means an angle of 50% of the amount of light with respect to the point at which the amount of ultraviolet light is maximum. Therefore, even in a region located at an angle deviating from the directivity angle Q, ultraviolet rays can be irradiated from the light source. If the transparent portion 250 is not formed sufficiently large, the ultraviolet light irradiated to the region deviating from the directivity angle Q is hit by the inner surface of the housing and is lost. However, it is difficult to increase the size of the transparent part 250 due to problems such as an increase in the manufacturing cost and a reduction in the strength of the housing.

In order to minimize the loss of ultraviolet rays, the distance d1 between the transparent portion 250 and the light source 230 may be minimized. For example, by minimizing the length d2 of the support 214 'located between the substrate 240 and the lower housing 212, the distance d1 can be minimized. For example, the length d2 of the supporting portion 214 'in the direction perpendicular to the substrate 240 is set such that the distance d1 between the light source 230 and the transparent portion 250 is about 200 μm or more and 2 mm or less Can be set.

A spacer 216 may be provided to define a predetermined distance d2 between the lower housing 212 and the evaporator 23 in order to have a wider sterilizing area B. [ The spacer 216 not only prevents the transparent portion 250 from being narrowed by the direct contact with the evaporator 23, but also makes it possible to maintain proper sterilizing power.

More specifically, if the transparent part 250 of the light source module 200 'is installed in direct contact with the evaporator 23, ultraviolet rays are irradiated only to the heat exchange plates contacting the transparent part, there is a problem. Further, if the light source module 200 'is separated from the evaporator 23 too much, there is a problem that the sterilizing power is lowered to an appropriate level or less.

A spacer 216 may be provided to form a predetermined distance d2 between the lower housing 212 and the evaporator 23 in order to prevent the sterilization area from being reduced and the sterilizing power from being lowered. For example, the length d2 in the direction perpendicular to the substrate 240 of the spacer 216 may be set to a length that is shorter than the length of the fastening portions 221 and 222, but maintains a proper sterilizing force. The width of the spacer 216 in the direction parallel to the substrate 240 is larger than the spacing distance between adjacent heat exchange plates so as to form a space between the evaporator 23 and the lower housing 212. [ .

In this case, for example, the length of the one transparent portion in the direction parallel to the substrate 240 may be long enough to cover ultraviolet rays emitted from the first and second light sources 230_1 and 230_2 . As another example, the light source module 230 " may include three or more transparent portions.

 As described above, since the light source module 200 '' is implemented to include a plurality of light sources and a plurality of corresponding transparent portions, the light source module 200 '' performs sterilization operation for a wider area .

Referring to FIGS. 13A and 13B, a guide rail 36 is installed in the evaporator 33. For example, the guide rails 36 may be installed in a direction parallel to the direction in which the plurality of heat exchange plates of the evaporator 33 extend. However, this is merely an example, and the guide rail 36 may be installed in various directions such as a direction perpendicular to the direction in which the plurality of heat exchange plates extend.

The light source module 300 is seated on the guide rail 36. 13B, the fastening portions 321_1 and 321_2 of the light source module 300 may be inserted into the guide grooves 36_11 and 36_21 formed on the guide rails 36_1 and 36_2, respectively, and fastened thereto . In this case, the guide grooves 36_11 and 36_21 may be formed by recessing the surface as shown, but the present invention is not limited thereto. For example, the guide grooves 36_11 and 36_21 may be formed protruding from the surface. As another example, grooves may be formed on both sides of the guide grooves 36-11 and 36_21. Thus, the guide grooves 36_11 and 36_21 can be formed in various shapes.

The light source module 300 is configured to be movable along the guide rail 36. For example, each of the fastening portions 321_1 and 321_2 of the light source module 300 may be provided with a roller for reducing frictional force. In the sterilizing operation, the light source module 300 moves along the guide rail 36, Operation can be performed. Therefore, the sterilization zone C sterilized by the light source module 300 is greatly widened along the direction in which the guide rails 36 extend.

Meanwhile, the sterilizing operation of the light source module 300 may be performed periodically or non-periodically. For example, the light source module 300 may perform a sterilizing operation while periodically moving along the guide rail 36 based on a predetermined time period. As another example, the light source module 300 may perform a sterilizing operation when the power supplied to the air conditioner 30 is cut off.

14 is a block diagram briefly showing the overall configuration of the air conditioner 40 according to the embodiment of the present application. For example, the air conditioner 40 of Fig. 14 can support a mobile sterilization operation similar to the air conditioner 30 and the light source module 300 described in Fig. The air conditioner 40 and the light source module 400 of FIG. 14 are similar to the air conditioner 30 and the light source module 300 of FIG. 13, and thus the repeated description will be omitted below for the sake of brevity.

Referring to FIG. 14, the air conditioner 40 includes an evaporator 43, a light source module 400, an auxiliary power source 430, a timer 440, and a controller 450.

The evaporator 43 includes a plurality of plates for heat exchange. A guide rail 36 (see FIG. 13A) is provided on one side of the evaporator 43 and provides a path through which the light source module 400 can move to the guide rail 36.

The light source module 400 is installed in close contact with the evaporator 43. For example, the light source module 400 may be mounted on the guide rail 36 installed in the evaporator 43, and may be reciprocated along the guide rail 36 to perform a sterilizing operation on the evaporator 43 Can be implemented. The light source module 400 includes an ultraviolet ray irradiating unit 410 and a moving unit 420.

The ultraviolet ray irradiating unit 410 irradiates the ultraviolet ray having a sterilizing effect toward the evaporator 43. For example, as shown in FIGS. 3 to 13, the light source, the substrate on which the light source is mounted, and the transparent portion disposed toward the front of the light source may be referred to as an ultraviolet ray irradiating portion 410. However, this is merely an example, and only the light source may be referred to as an ultraviolet irradiation unit 410. As another example, the light source and the substrate may be referred to as an ultraviolet ray irradiating portion 410. In another example, the light source, the substrate, the transparent portion, and the housing may be referred to as an ultraviolet ray irradiating portion 410.

The moving part 420 allows the light source module 400 to move along the guide rail 36. For example, the moving part 420 may be implemented to include an electrically driven small motor and a wheel connected to the small motor. The moving part 420 is connected to the coupling parts 321_1 and 321_2 of the light source module 400 so that the light source module 400 can be moved along the guide rail 36. [

The auxiliary power unit 430 supplies power to the light source module 400. In particular, the auxiliary power unit 430 supplies power to the light source module 400 so that the light source module 400 can perform a sterilizing operation when the external power source is shut off. The auxiliary power supply unit 430 may be implemented using, for example, a small battery, a large capacity capacitor, a supercapacitor, or the like.

The timer 440 checks the operating time of the air conditioner 40. For example, the timer 440 may check the operating time of the air conditioner 40 and provide it to the controller 450.

The control unit 450 controls the overall operation of the air conditioner 40. In particular, the controller 450 controls the sterilizing operation of the light source module 400 based on the information about the operating time of the air conditioner provided from the timer 440 of the air conditioner 40 and information on whether or not the power source of the external power source is turned off .

For example, when the operation time of the air conditioner reaches a predetermined time period, the controller 450 controls the light source module 400 to perform the sterilization operation. In particular, as illustrated in FIG. 13, the light source module 400 may perform a sterilizing operation while moving along the guide rail 36. [0053] FIG. After the sterilization operation is completed, the controller 450 may reset the timer 440 again and the timer 440 may check the air conditioner operation time from the beginning.

The control unit 450 controls the sub power unit 430 to provide the power source of the sub power unit 430 to the light source module 400. In this case, In addition, the controller 450 controls the light source module 400 to perform the sterilizing operation. In this case, similarly, the light source module 400 can perform the sterilization operation while moving along the guide rail 36.

As described above, the air conditioner 40 according to one embodiment of the present application may perform sterilization operation periodically and may perform the sterilization operation non-periodically, such as when a power-off signal is received. In this manner, by allowing the air conditioner 40 to perform the sterilizing operation automatically without any external command, the air conditioner 40 of the present application can further improve user convenience.

15 is a flowchart for explaining the operation of the air conditioner 40 of Fig.

In step S110, power is supplied to the air conditioner 40, and in step S120, the air conditioner 40 performs an operation. For example, the air conditioner 40 will perform a cooling operation after power input.

In step S130, the timer 440 starts operating. For example, the timer 440 can check the operation time of the air conditioner 40 at the same time when power is supplied to the air conditioner 60 in response to the control of the controller 450. As another example, the timer 440 may check the operation time of the air conditioner 60 after a predetermined time after power is supplied to the air conditioner 40.

In step S140, the controller 450 determines whether the air conditioner operating time Tc provided from the timer 440 has reached a predetermined time period Tr.

The controller 450 controls the light source module 400 to perform the sterilizing operation for the evaporator 43 when the air conditioner operation time Tc reaches the predetermined time period Tr. That is, in step S150, the light source module 400 may perform the sterilizing operation while moving along the guide rails provided in the evaporator 43. [ Thereafter, after the sterilization operation is completed, the control unit 450 resets the timer 440 in step S150. Thereafter, the timer 440 again starts the check time for the air conditioner operation time.

In step S150, the controller 450 determines whether the external power source is off. For example, the control unit 450 may receive information on whether the external power source is shut off based on a power-off signal received from the outside.

If the external power is shut off, the controller 450 controls the auxiliary power unit 430 and the light source module 400 so that the sterilizing operation of the evaporator 43 is performed. That is, in step S170, the auxiliary power unit 430 provides power to the light source module 400 in response to the control of the controller 450. [ Thereafter, in step S180, the light source module 400 performs a sterilizing operation while moving along the guide rails provided in the evaporator 43. [

On the other hand, if the external power is not interrupted, the timer 440 will continue to check the running time of the air conditioner.

The above description is illustrative, and the technical idea of the present application is not limited thereto. For example, the order of operations in Fig. 15 may be changed in some order depending on the designer. For example, before step S140 of comparing the air conditioner operation time with a predetermined time period, step S145 of determining whether the external power source is powered off can be performed.

16 is a view showing an embodiment of the air conditioner 50 and the light source module 500 installed in the air conditioner 50 according to an embodiment of the present invention. 16A is a schematic view illustrating a light source module 500 that can be moved along a guide rail 36 installed in an evaporator 53. FIG. 16B is a perspective view illustrating the light source module 500 of FIG. 16A in more detail . 16C to 16E are sectional views showing a section of the light source module 500 of FIG. 16B.

The air conditioner 50 and the light source module 500 of FIG. 16 are similar to the air conditioner 30 and the light source module 30 of FIG. Accordingly, the same or similar components are denoted by the same or similar reference numerals, and the repeated description will be omitted below for the sake of brevity.

First, referring to FIG. 16A, a guide rail 56 is installed in the evaporator 53. For example, the guide rails 56 may be installed in a direction parallel to the direction in which the plurality of heat exchange plates of the evaporator 53 extend. However, this is merely an example, and the guide rail 56 may be installed in various directions such as a direction perpendicular to the direction in which the plurality of heat exchange plates extend. The light source module 500 is coupled to the guide rail 56 and moves along the guide rail 56 to perform the sterilization operation periodically or aperiodically.

In one embodiment of the present invention, the light source module 500 includes a light source unit that emits ultraviolet rays, and the direction of ultraviolet emission of the light source unit may be changed according to the direction of the light source unit. That is, the light source module 500 according to the embodiment of the present invention provides a function of rotating the light source unit in which the ultraviolet ray output direction can be changed.

As such, since the ultraviolet ray output direction of the light source unit is variable, the light source module 500 according to the embodiment of the present invention can perform sterilization operation for a wider area. 16A, the light source module 500 not only sterilizes the area D by controlling the light source part so as to face the upper part 53_1 of the evaporator 53, The sterilizing operation for the region E can be performed by controlling the light source portion so as to face the lower portion 53_2 of the region E. In this case, the region D and the region E may not overlap with each other, and thus sterilization operation for a wider area may be performed.

Referring to FIG. 16B, a light source module 500 is shown. The light source module 500 includes a housing 510 and a light source 520. The housing 510 is formed with fastening portions 525_1 and 525_2 fastened to guide grooves of the guide rail 56. [

The light source unit 520 includes a protection tube 523 for protecting the light source 521, the substrate 522, the light source 520 and the substrate 522 and bases 524_1 and 524_2 provided at both ends of the protection tube 523 , And has a cylindrical shape as a whole. The light source 520 is rotatable about the center axis of the cylinder. Accordingly, the light is generally emitted in the upward direction, but the direction of light emission can be changed depending on whether the light source unit 520 is rotated or not.

The light source 520 is provided on one side of the housing 510. The housing 510 forms an outer appearance of the light source module 500 and provides a space in which the light source 520, the printed circuit board for driving the light source 520,

The housing 510 is provided with a pivot ring which is an annular structure for supporting the light source unit 520 by surrounding both ends of the light source unit 520. The light source 520 is inserted into the pivot ring and fixed therein in a rotatable manner. In addition, the housing 510 is provided with a fastening member for fastening the light source module to the external component.

The housing 510 can be provided as an assembled assembly of a plurality of parts fastened to each other. For example, the housing 510 includes an upper housing and a lower housing coupled to each other. However, the housing 510 can be made of a larger number of parts.

The fastening portions 525_1 and 525_2 are formed in the upper housing and are inserted into the guide rails 56 to allow linear motion. However, the fastening portions 525_1 and 525_2 may be formed anywhere in the upper housing 510 or the lower housing 120 considering the shape and arrangement of the fastening portions 525_1 and 525_2.

16 c to 16e, the light source 520 is rotatable along the pivot axis PV, which is the central axis in the longitudinal direction. When the light source unit 520 rotates, the light source 521 mounted in the light source unit 520 can also rotate to the same degree as the rotation of the bases 524_1 and 524_2.

The bases 524_1 and 524_2 may be provided with hooking protrusions 531 projecting toward the side of the upper housing 510 along the direction of the light source unit 520. [ The latching jaw 531 is rotatable about the insertion protrusion 532 located on the pivot axis PV of the light source unit 520 in accordance with the rotation of the light source unit 520.

In the embodiment of the present invention, the direction of light emitted from the light source 521 may be changed within a predetermined angle with respect to the pivot axis PV. 533 may be provided. The stopper 533 is disposed at a position which obstructs the rotation direction of the latching jaw 531 so as to limit the rotation range of the latching jaw 531. [ At this time, the latching jaw 531 is provided between the pair of stoppers 533, so that when the latching jaw 531 rotates in the clockwise direction and the counterclockwise direction, The rotation angle is limited. The position of the stopper 533 may be set differently depending on the emitting direction of the light emitted from the light source 520 and the emitting angle of the emitted light.

In one embodiment of the present invention, the shapes of the latching jaw 531 and the stopper 533 can be variously modified. For example, the latching jaw 531 may extend radially from the insertion protrusion 532 when viewed in cross-section, as shown. The surface of the latching jaw 531 in contact with the pivot ring 110a may have a shape of a circle, for example, a semicircle, or arc, to facilitate rotation. However, the shape of the latching jaw 531 is not limited to this, and movement of the latching jaw 531 may be blocked by the stopper 533. The shape of the latching jaw 531 may have various shapes such as a rectangle, a circle, an ellipse, . Also, although the stopper 533 is shown as a pair of bar shapes as shown in the figure, the stopper 533 is not limited thereto as long as the stopper 533 can prevent rotation of the stopper 531.

16C shows that the substrate 522 of the light source 521 is parallel to the bottom surface of the lower housing 120 when the light source unit 520 is not rotated. The light source 521 emits light vertically upward from the upper surface of the light source module, that is, in the first direction D1.

16D shows that the substrate 522 of the light source 521 is inclined with respect to the bottom surface of the housing 100 when the light source unit 520 rotates clockwise at maximum. The light source unit 520 can be rotated in a clockwise direction until the stopper 533 catches the stopper 531. At this time, the light source 521 emits light in the clockwise direction, that is, in the second direction D2, from above perpendicularly to the upper surface of the light source module.

16E shows that the light source unit 520 is rotated in the counterclockwise direction as much as possible and the substrate 522 of the light source 521 is inclined in the direction opposite to FIG. 16D. The light source unit 520 is rotated in the counterclockwise direction and can rotate until the stopper 533 catches the stopper 531. The light source 521 emits light in a direction inclined counterclockwise from the upper side perpendicular to the upper surface of the light source module, that is, in the third direction D3.

As a result, according to an embodiment of the present invention, light can be emitted from the light source 520 within an angle formed by the third direction D3 from the second direction D2. Since the second direction D2 and the third direction D3 are based only on the direction perpendicular to the surface of the substrate 522 of the light source 521, the angle at which the actual light is emitted is in the second direction D2, And is greater than the angle between the third direction D3.

The light source module according to an embodiment of the present invention having the above-described structure can rotate the light source unit 520, and thus can adjust the direction of light emitted from the light source unit 520 variously. In particular, when the light source module 500 performs the sterilizing operation periodically or aperiodically with respect to the evaporator, the sterilizing region can be greatly expanded by rotating the light source portion 520.

17 is a block diagram briefly showing an overall configuration of an air conditioner 60 according to an embodiment of the present application. For example, the air conditioner 60 of FIG. 17 can adjust the direction of light emitted similarly to the air conditioner 50 and the light source module 500 described in FIG.

The air conditioner 60 and the light source module 600 of Figure 17 are similar to the air conditioners 40 and 50 and the light source modules 400 and 500 of Figures 14 and 16 and thus the repeated description is omitted herein for the sake of brevity will be. Referring to FIG. 17, the air conditioner 60 includes an evaporator 63, a light source module 600, an auxiliary power source 630, a timer 640, and a controller 650.

Unlike the light source module 400 of FIG. 14, the light source module 600 of FIG. 17 further includes a rotation adjuster 625. The rotation adjusting unit 625 rotates the light source unit 520 (see FIG. 16) included in the light source module 600 to adjust the direction of the emitted light. For example, the rotation control unit 625 may be connected to a pivot axis which is a center axis of the light source unit 520 in the longitudinal direction, and may perform an operation of rotating the light source unit 520 under the control of the control unit 650.

The rotation regulating unit 625 can rotate the light source unit 520 based on whether or not the sterilizing operation time for the specific direction has reached the reference time.

For example, the control unit 650 may receive information on the sterilization operation time for the first region of the evaporator 63 from the timer. The control unit 650 can determine whether the sterilization operation time for the first region has reached the reference time by comparing the sterilization operation time for the first region with the reference time. If the time of the sterilization operation for the first region has reached the reference time, the rotation regulator 625 performs a sterilization operation for the second region that does not overlap with the first region in response to the control of the controller 650 The light source unit 520 can be rotated.

In addition, the rotation adjusting unit 625 can perform the sterilizing operation in conjunction with the moving unit 620. That is, in the sterilizing operation, the light source module 600 not only performs the reciprocating linear motion along the guide rails provided in the evaporator 63 by the moving part 620, Can be adjusted.

For example, the rotation adjusting unit 625 may rotate the light source unit 520 so that ultraviolet rays are irradiated toward the upper portion of the evaporator 63 first. The light source module 600 can perform a reciprocating linear motion along the guide rail by the moving unit 620 in a state where the light source unit 520 is fixed such that the emitting direction of the ultraviolet ray is directed to the upper side of the evaporator 63 . Therefore, the sterilization operation for the area D (see Fig. 16A) can be performed first.

Thereafter, when the sterilizing operation time for the region D reaches a predetermined reference time, the rotation regulating portion 625 can rotate the light source portion 520 such that the direction of the ultraviolet light is directed to the lower portion of the evaporator 63 have. The light source module 600 can perform a reciprocating linear motion along the guide rail by the moving unit 620 in a state where the light source unit 520 is fixed such that the emitting direction of ultraviolet rays is directed to the lower side of the evaporator 63 . Accordingly, the sterilization operation for the region E (see Fig. 16A) can be performed.

As described above, the air conditioner 60 according to the embodiment of the present application not only controls the direction in which ultraviolet rays are emitted during the sterilizing operation of the evaporator 63, but also controls the sterilizing operation while moving the light source module 600 Can be performed. Accordingly, the light source module 600 can effectively perform a sterilizing operation over a large area.

18 is a flowchart for explaining the operation of the air conditioner 60 of Fig.

In step S210, power is supplied to the air conditioner 60, and in step S220, the cooling operation of the air conditioner 60 is performed. In step S230, the timer 640 starts operating. For example, the timer 640 may check the running time of the air conditioner 60. [

In step S240, the controller 650 determines whether the air conditioner operating time Tc provided from the timer 640 has reached a predetermined time period Tr.

The control unit 650 controls the light source module 600 to perform the sterilizing operation on the first area of the evaporator 63 when the air conditioner operation time Tc reaches the predetermined time period Tr.

That is, in step S251, the rotation adjusting unit 625 rotates the light source unit 520 such that the emitting direction of the ultraviolet ray is directed to the first region, and the light source module 600 moves along the guide rails provided on the evaporator 63 A sterilization operation for the first area will be performed.

Thereafter, in step S252, the controller 650 determines whether the sterilizing operation time for the first area has reached a predetermined first reference time.

If the reference time has not been reached, the light source module 600 will continue to perform the sterilization operation for the first area.

If the reference time has been reached, the control unit 650 controls the light source module 600 to perform a sterilizing operation on the second area of the evaporator 63. [

That is, in step S253, the control unit 650 rotates the light source unit 520 such that the direction of the ultraviolet rays is directed toward the second area of the evaporator 63, and the light source module 600 guides the guide rails provided on the evaporator 63 So that the sterilizing operation for the second area will be performed.

Thereafter, in step S252, the controller 650 determines whether the sterilization operation time for the second area has reached a predetermined first reference time.

If the second reference time has not been reached, the light source module 600 will continue to perform the sterilization operation for the second area.

If the second reference time has been reached, the controller 650 determines that the sterilizing operation has been completed and stops the sterilizing operation. In this case, after the timer 640 is reset in step S260, the timer 640 starts checking the operation time of the air conditioner 60 again.

On the other hand, if it is determined in step S240 that the air conditioner operation time Tc has not reached the predetermined time period Tr, the control unit 650 determines in step S245 whether a power off signal of the external power source has been received.

If the power off signal of the external power source is received, the controller 650 controls the auxiliary power source unit 630 and the light source module 600 to perform the sterilizing operation on the evaporator 63. [

That is, in step S270, the auxiliary power unit 630 provides power to the light source module 600 in response to the control of the controller 650. [ Thereafter, in step S280, the light source module 600 performs a sterilizing operation on the first area and the second area while moving along the guide rails provided on the evaporator 63. [ For example, in accordance with the procedure described in steps S251 to S254, the light source module 600 may perform a sterilization operation for the first area and the second area.

The above description is illustrative, and the technical idea of the present application is not limited thereto. For example, the order of operations in Fig. 18 may be changed in some order depending on the designer. For example, it will be appreciated that step S245 may be performed before step S240 of comparing the air conditioner operating time with a predetermined time period to determine whether the external power source is powered off.

Further, although not shown, the air conditioners 30, 40, 50, and 60 of FIGS. 13 to 16 may further include a photocatalyst layer for photocatalytic reaction. For example, the air conditioners 30, 40, 50, and 60 may each include a photocatalyst filter, and the light sources of the light source modules 200, 300, 400, 500, and 600 may irradiate the ultraviolet can do. As another example, the photocatalyst material may be coated on the evaporator 23, 33, 43, 53, 63, and the light source of the light source modules 200, 300, 400, 500, 600 may irradiate the ultraviolet You can investigate. In this case, since the organic compound is decomposed by the photocatalytic reaction and the bacteria are sterilized, the deodorizing and sterilizing effect can be further enhanced.
