DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of an indoor unit of an air conditioner will be described below with reference to the drawings. The indoor unit 10 of the air conditioner shown in FIG. 1 is an indoor unit that is embedded in the ceiling of a room, which is the space to be air-conditioned, that is, a so-called ceiling-embedded indoor unit. The indoor unit 10 includes a housing 11 and a decorative panel 12. The housing 11 is inserted from the indoor side into a rectangular opening (not shown) provided in the ceiling. The housing 11 is then fixed in a suspended state above the ceiling by means of hanging bolts (not shown) or the like. The decorative panel 12 is attached below the housing 11 in a state where it is exposed to the indoor side.

[0009] The decorative panel 12 is formed in a generally rectangular plate shape. The decorative panel 12 is provided with an air inlet 13 that draws in air from within the room and an air outlet 14 that blows air into the room. The air inlet 13 is formed in a generally square shape in the center of the decorative panel 12. The air inlet 13 is configured as a so-called air intake grill that opens in a lattice pattern to allow ventilation. The air outlet 14 forms a long opening along each side of the air inlet 13. The air outlet 14 is provided with rotatable louvers 14a that adjust the direction of the air blown out from the air outlet 14.

[0010] As shown in FIG. 2, the housing 11 forms the outer contours of the top and side surfaces of the indoor unit 10. The housing 11 has a box-like shape with side walls, a top wall, and a bottom opening. The side walls of the housing 11 are provided in a wall-like shape so as to close the side surfaces of the housing 11. The top wall of the housing 11 is provided in a wall-like shape so as to close the top surface of the housing 11. The bottom opening of the housing 11 is a roughly rectangular opening that opens the bottom surface of the housing 11. The decorative panel 12 covers the bottom opening of the housing 11 from below. The housing 11 contains a blower 15, a heat exchanger 16, and the like.

[0011] The blower 15 is disposed in the center of the housing 11. The blower 15 is also disposed above the air inlet 13. The heat exchanger 16 is disposed so as to surround the periphery of the blower 15. The heat exchanger 16 is also disposed above the decorative panel 12, between the air inlet 13 and the air outlet 14. The heat exchanger 16, together with a compressor and an outdoor heat exchanger (not shown), constitutes a well-known refrigeration cycle and is capable of heating and cooling air.

[0012] As shown by the dashed arrow W in Figure 2, the indoor unit 10 drives the blower 15 to draw in indoor air through the air inlet 13, exchange heat with the drawn-in air through the heat exchanger 16, and blow out the heat-exchanged air from the air outlet 14. This allows the indoor unit 10 to perform air conditioning control to adjust the indoor temperature to a predetermined set temperature.

[0013] The indoor unit 10 also includes a drain pan 17 within the housing 11. The drain pan 17 is disposed between the decorative panel 12 and the heat exchanger 16. The drain pan 17 is disposed so as to fill the upper portion between the air inlet 13 and the air outlet 14. The drain pan 17 is disposed below the heat exchanger 16 and receives drain water generated from the heat exchanger 16. The drain water received by the drain pan 17 is then stored within the drain pan 17.

[0014] The indoor unit 10 also includes a heat insulating member 18 within the housing 11. The heat insulating member 18 is made of a material with heat insulating properties, such as polystyrene foam. Like the housing 11, the heat insulating member 18 has a box-like shape with side walls, a top wall, and a bottom opening. The side walls of the heat insulating member 18 are provided in a wall-like shape so as to close the side of the heat insulating member 18. The top wall of the heat insulating member 18 is provided in a wall-like shape so as to close the top surface of the heat insulating member 18. The bottom opening of the heat insulating member 18 is a roughly rectangular opening that leaves the bottom surface of the heat insulating member 18 open.

[0015] When the heat insulating member 18 is placed inside the housing 11, the outer surfaces of the side wall portions of the heat insulating member 18 are arranged along the inner surfaces of the side wall portions of the housing 11. Furthermore, when the heat insulating member 18 is placed inside the housing 11, the outer surface of the top wall portion of the heat insulating member 18 is arranged along the inner surface of the top wall portion of the housing 11. Furthermore, when the heat insulating member 18 is placed inside the housing 11, the bottom opening of the heat insulating member 18 is arranged inside the bottom opening of the housing 11.

[0016] The indoor unit 10 also includes a drain pump 19 for discharging water accumulated in the drain pan 17 to the outside of the unit. As shown in Figure 3, a downwardly recessed water storage section 17a is provided in the portion of the drain pan 17 located below the drain pump 19. A water inlet 19a provided at the bottom end of the drain pump 19 extends into this water storage section 17a, allowing the drain pump 19 to smoothly suck in water.

[0017] 4, 5, and 6, the indoor unit 10 is equipped with an ultraviolet irradiation device 20, which is an example of an ultraviolet irradiation unit. The ultraviolet irradiation device 20 includes a light source capable of emitting ultraviolet light, such as an ultraviolet LED (Light Emitting Diode), and a board that controls the light emission from the light source, and is configured to be able to irradiate ultraviolet light particularly toward the water storage section 17a of the drain pan 17. The indoor unit 10 also includes an ultraviolet irradiation unit fixing member 100 for fixing the ultraviolet irradiation device 20.

[0018] As shown in FIG. 7, the ultraviolet irradiation unit fixing member 100 integrally includes a co-tightening portion 101 that is fixed or co-tightened with the drain pump 19, and an ultraviolet irradiation unit fixing portion 102 that fixes the ultraviolet irradiation device 20.

[0019] The co-tightening portion 101 extends toward the drain pump 19. Both ends of the co-tightening portion 101 further extend toward the drain pump 19 and have screw holes 101a.

[0020] The ultraviolet irradiation unit fixing unit 102 has a housing unit 102a that houses the ultraviolet irradiation device 20, a housing unit fixing unit 102b that fixes the housing unit 102a, and a connecting unit 102c that connects the housing unit 102a and the housing unit fixing unit 102b. A thin-walled hinge unit 102d is interposed between the housing unit fixing unit 102b and the connecting unit 102c, and the ultraviolet irradiation unit fixing unit 102 integrally includes the housing unit 102a, the housing unit fixing unit 102b, and the connecting unit 102c.

[0021] As shown in Fig. 8, the accommodation section 102a is provided with an irradiation port 102e. The ultraviolet irradiation device 20 is a control board on which an ultraviolet LED is mounted, and as shown in Fig. 7, the ultraviolet irradiation device 20 is accommodated in the accommodation section 102a so that the irradiation port 102e and the ultraviolet LED face each other, and is fixed to the accommodation section 102a with screws 102f.

[0022] 7, the fixing portion 102b is provided so as to be inclined toward the co-tightening portion 101. Furthermore, locking walls 102g that lock onto the side surfaces of the accommodating portion 102a are formed on both ends of the fixing portion 102b. Locking holes 102i that lock onto locking claws 102h provided on the side surfaces of the accommodating portion 102a are formed in the locking walls 102g.

[0023] As shown in FIG. 8, by bending the accommodation portion 102a and the connecting portion 102c via the hinge portion 102d, the locking claw 102h is engaged with the locking hole 102i, and the accommodation portion 102a is closed by the fixing portion 102b.

[0024] The ultraviolet irradiation device 20 fixed to the ultraviolet irradiation unit fixing part 102 is inclined so that the irradiation port 102e for emitting ultraviolet rays is directed toward the water storage part 17a of the drain pan 17. As a result, the ultraviolet irradiation device 20 is positioned in a state in which it can irradiate ultraviolet rays toward the water storage part 17a.

[0025] The ultraviolet irradiation unit fixing member 100 further includes an integral float switch fixing portion 103. The float switch fixing portion 103 is provided on the side of the ultraviolet irradiation unit fixing portion 102. The float switch fixing portion 103 is formed with a holding hole 103a for holding the float switch 21. The float switch fixing portion 103 is also formed with a slit 103b that is continuous with the holding hole 103a.

[0026] The float switch 21 is an example of a water level detection part for detecting the water level in the drain pan 17, and includes a switch main body 21a and a holding pillar 21b. The float switch 21 is fixed to the float switch fixing part 103 by inserting the holding pillar 21b into the holding hole 103a and tightening the holding pillar 21b with a nut or the like.

[0027] 9, the ultraviolet irradiation device 20 fixed to the ultraviolet irradiation unit fixing member 100 is disposed at a position higher than the upper limit of the detection range H of the float switch 21 and lower than the upper end 17b of the drain pan 17. The detection range H of the float switch 21 defines the range of water levels that can be detected by the float switch 21. The float switch 21 switches from an ON state to an OFF state when the water level in the drain pan 17 is outside the detection range H, and switches from an OFF state to an ON state when the water level in the drain pan 17 is within the detection range H.

[0028] The control device 30 illustrated in FIG. 10 is primarily configured with a microcomputer, for example, and is capable of controlling the overall operation of the indoor unit 10 based on a control program, setting data, etc. When the float switch 21 is in the OFF state, that is, when the water level in the drain pan 17 is lower than the lower limit of the detection range H, the control device 30 operates the indoor unit 10 based on the control program, setting data, etc. However, when the float switch 21 switches from the OFF state to the ON state, the control device 30 stops the operation of the indoor unit 10. In other words, when the water level in the drain pan 17 falls within the detection range H of the float switch 21, the control device 30 stops the operation of the indoor unit 10. This prevents heat exchange by the heat exchanger 16 and the generation of drain water, thereby preventing the water level in the drain pan 17 from rising further and preventing the ultraviolet irradiation device 20 from being submerged. Furthermore, this also prevents water from overflowing from the drain pan 17.

[0029] The control device 30 can also execute agitation control while the ultraviolet irradiation device 20 is irradiating ultraviolet rays. As shown in FIG. 11 , this agitation control alternates between an operating state and a stopped state of the drain pump 19 while the ultraviolet irradiation device 20 is irradiating ultraviolet rays. This alternates between a period in which the drain pump 19 sucks water from the water storage portion 17a of the drain pan 17 and a period in which the water returns from the drain pump 19 to the water storage portion 17a of the drain pan 17, thereby agitating the water in the water storage portion 17a of the drain pan 17. This allows the water in the drain pan 17 to be uniformly irradiated with ultraviolet rays, effectively suppressing the growth of microorganisms.

[0030] 12, the fixing portion 40 to which the drain pump 19 is fixed is provided at a corner within the heat insulating member 18. The fixing portion 40 is formed in a stepped or shelf-like shape at the corner within the heat insulating member 18. A drain pump fixing member 200 for fixing the drain pump 19 is attached to the fixing portion 40.

[0031] 13, the drain pump fixing member 200 is configured by combining an inner member 201 and an outer member 202. The inner member 201 has a circular inner member main body 201a. The inner member 201 also has a plurality of extension portions 201b (in this case, three) extending radially from the inner member main body 201a. A screw hole 201c is formed at the tip of each of the extension portions 201b.

[0032] Of the multiple extending portions 201b, two extending portions 201b each have one screw hole 201c formed therein. Furthermore, of the multiple extending portions 201b, one extending portion 201b has multiple, in this case, two screw holes 201c formed therein. Furthermore, the inner member 201 includes a positioning portion 201d extending from the inner member main body portion 201a. The positioning portion 201d is formed in a rectangular shape.

[0033] 14, a locking claw 201e is formed in the center of the inner member main body 201a. The locking claw 201e extends toward the outer member 202. The tip of the locking claw 201e is divided into two parts and is elastically deformable along the radial direction of the inner member 201. The inner member 201 also has a plurality of screw receiving portions 201f (two in this case) arranged so as to sandwich the locking claw 201e.

[0034] 13, the fixing part 40 on the heat insulating member 18 side has a fitting groove 41 formed therein into which the inner member 201 is fitted. The fitting groove 41 has a fitting groove main body 41a into which the inner member main body 201a of the inner member 201 is fitted, an extension groove 41b into which the extension part 201b of the inner member 201 is fitted, and a positioning groove 41d into which the positioning part 201d of the inner member 201 is fitted.

[0035] An insertion hole 41e, through which the locking claw 201e of the inner member 201 is inserted, is formed in the center of the fitting groove 41. The fitting groove 41 also has a plurality of, in this case, two, insertion holes 41f, through which the screw receiving portions 201f of the inner member 201 are inserted.

[0036] The outer member 202 also has a locking hole 202b in the center of a rectangular, plate-shaped outer member main body 202a, and a plurality of screw holes 202c (two in this case) arranged on either side of the locking hole 202b.

[0037] As illustrated in FIG. 15 , the drain pump fixing member 200 is attached with the fixing portion 40 sandwiched between the inner member 201 and the outer member 202. When the fixing portion 40 is sandwiched between the inner member 201 and the outer member 202, the locking claw 201e of the inner member 201 passes through the insertion hole 41e and engages with the locking hole 202b of the outer member 202. This temporarily fixes the inner member 201 and the outer member 202 with the fixing portion 40 sandwiched between them. Then, the inner member 201 and the outer member 202 with the fixing portion 40 sandwiched between them are fixed by threading a screw 203, illustrated in FIG. 13 , through the screw hole 202c into the screw receiving portion 201f. This completely fixes the inner member 201 and the outer member 202 with the fixing portion 40 sandwiched between them.

[0038] The drain pump 19 can be fixed to the drain pump fixing member 200 fixed to the fixing portion 40 in the above manner. That is, as shown in FIG. 6, the multiple arm portions 19b of the drain pump 19 are fixed by screws 50 to the screw holes 201c of the drain pump fixing member 200. In this way, the drain pump 19 is firmly fixed to the fixing portion 40.

[0039] The ultraviolet irradiation unit fixing member 100 described above can also be fixed to the fixing portion 40 together with the drain pump 19. That is, the co-fastening portion 101 of the ultraviolet irradiation unit fixing member 100 is fixed together with the arm portion 19b of the drain pump 19 by the screw 50 into the screw hole 201c of the drain pump fixing member 200. In this way, the ultraviolet irradiation unit fixing member 100 is fixed to the fixing portion 40 together with the drain pump 19. That is, the ultraviolet irradiation unit fixing member 100 can be so-called "co-fastened" to the fixing portion 40 together with the drain pump 19.

[0040] In the air conditioner indoor unit 10 exemplified above, the ultraviolet irradiation unit fixing member 100 that fixes the ultraviolet irradiation device 20 is fixed together with the drain pump 19 to the fixing part 40 to which the drain pump 19 is fixed. According to this configuration example, the ultraviolet irradiation device 20 can be arranged compactly together with the drain pump 19.

[0041] Furthermore, the drain pump 19 mounted on this type of indoor unit 10 is designed to be mountable on many different models. In other words, the drain pump 19 is designed to be shared by many different models. Therefore, an ultraviolet irradiation unit fixing member 100 designed to fix a certain drain pump 19 can also be used with other models, eliminating the need to change the design of the ultraviolet irradiation unit fixing member 100 for each model.

[0042] Furthermore, according to the indoor unit 10, the ultraviolet irradiation unit fixing member 100 can also fix the float switch 21 that detects the water level in the drain pan 17. According to this configuration example, there is no need to provide a member for fixing the float switch 21 separately from the ultraviolet irradiation unit fixing member 100, and an increase in the number of parts can be suppressed.

[0043] Furthermore, according to the indoor unit 10, the control device 30 can execute control to switch the drain pump 19 between an operating state and a stopped state while ultraviolet rays are being irradiated by the ultraviolet irradiation device 20. According to this control example, ultraviolet rays can be irradiated while stirring the water in the water storage section 17a of the drain pan 17, and the proliferation of microorganisms can be effectively suppressed.

[0044] Furthermore, according to the indoor unit 10, the ultraviolet irradiation device 20 is fixed to the ultraviolet irradiation unit fixing member 100, and is therefore provided at a position higher than the upper limit of the detection range H of the float switch 21 and lower than the upper end 17b of the drain pan 17. According to this configuration example, it is possible to prevent the ultraviolet irradiation device 20 from being submerged in the water in the drain pan 17, and also possible to prevent water from overflowing from inside the drain pan 17.

[0045] Furthermore, according to the indoor unit 10, the drain pump fixing member 200 is attached in a state in which it sandwiches the fixing portion 40 to which the drain pump 19 is fixed. According to this configuration example, the drain pump 19 can be fixed without inserting a metal plate or the like having screw holes into the heat insulating member 18, and the drain pump 19 can be fixed with an inexpensive configuration.

[0046] It should be noted that this embodiment is not limited to the above-described embodiment, and various modifications and extensions can be made without departing from the spirit of the present invention.

[0047] For example, Figures 16 and 17 show modified examples of the drain pump fixing part. That is, the drain pump fixing part 300 is configured by combining an inner member 301 and an outer member 302. The inner member 301 has a circular inner member main body 301a. The inner member 301 also has multiple, in this case three, extension parts 301b extending radially from the inner member main body 301a. A screw hole 301c is formed at the tip of each extension part 301b. The inner member 301 also has positioning parts 301d extending radially from the inner member main body 301a. The positioning parts 301d are formed in a rectangular shape.

[0048] Furthermore, a circular screw hole 301e is formed in the center of inner member main body 301a. Furthermore, a plurality of locking holes 301f (two in this case) are formed in inner member main body 301a on either side of screw hole 301e. Locking holes 301f are rectangular in shape.

[0049] On the other hand, a fitting groove 341 into which the inner member 301 is fitted is formed in the fixing part 40 on the heat insulating member 18 side. The fitting groove 341 has a fitting groove main body 341a into which the inner member main body 301a of the inner member 301 is fitted, an extension groove 341b into which the extension part 301b of the inner member 301 is fitted, and a positioning groove 341d into which the positioning part 301d of the inner member 301 is fitted.

[0050] A screw hole 341e corresponding to the screw hole 301e of the inner member 301 is formed in the center of the fitting groove 341. A plurality of insertion holes 341f (two in this case) are formed on either side of the screw hole 341e in the fitting groove 341. The insertion holes 341f open in a rectangular shape corresponding to the locking hole 301f of the inner member 301.

[0051] The outer member 302 also has a screw receiving portion 302b in the center of a circular outer member main body 302a. The outer member 302 also has multiple, in this case two, locking claws 302c. The locking claws 302c extend from the outer periphery of the outer member main body 302a toward the inner member 301. The outer member main body 302a is provided at positions facing each other with the screw receiving portion 302b in between. The locking claws 302c are elastically deformable in the radial direction of the outer member 302.

[0052] The drain pump fixing member 300 is attached with the fixing portion 40 sandwiched between the inner member 301 and the outer member 302. With the fixing portion 40 sandwiched between the inner member 301 and the outer member 302, the locking claws 302c of the outer member 302 pass through the insertion holes 341f and lock into the locking holes 301f of the inner member 301. This temporarily fixes the inner member 301 and the outer member 302 with the fixing portion 40 sandwiched between them. The inner member 301 and the outer member 302 with the fixing portion 40 sandwiched between them are then fixed by threading the screws 303 through the screw holes 301e and 341e into the screw receiving portions 302b. This completely fixes the inner member 301 and the outer member 302 with the fixing portion 40 sandwiched between them.

[0053] 17, the inner member 301 has a rotation inhibiting groove 301g in part of the screw hole 301e. Meanwhile, the outer member 302 has a rotation inhibiting rib 302g in part of the screw receiving portion 302b. Both the rotation inhibiting groove 301g and the rotation inhibiting rib 302g extend in the direction in which the screw receiving portion 302b extends, i.e., along the axial direction of the drain pump fixing member 300.

[0054] When the inner member 301 and the outer member 302 are combined with the fixing portion 40 sandwiched therebetween, the rotation preventing rib 302g of the outer member 302 fits into the rotation preventing groove 301g of the inner member 301. This prevents the inner member 301 from rotating relative to the outer member 302, or the outer member 302 from rotating relative to the inner member 301, when the screw 303 is screwed into the screw receiving portion 302b. The rotation preventing groove 301g and the rotation preventing rib 302g function as an example of a rotation preventing portion that prevents the drain pump fixing member 300 from rotating in the fixing portion 40 to which the drain pump 19 is fixed, or prevents the inner member 301 or the outer member 302 that constitutes the drain pump fixing member 300 from rotating.

[0055] The drain pump 19 can also be fixed to the drain pump fixing member 300 fixed to the fixing portion 40 in the above manner. That is, the arm portions 19b of the drain pump 19 are fixed to the screw holes 301c of the drain pump fixing member 200 with the screws 50. This allows the drain pump 19 to be firmly fixed to the fixing portion 40.

[0056] The ultraviolet irradiation unit fixing member 100 can also be fixed to the fixing portion 40 together with the drain pump 19. That is, the co-fastening portion 101 of the ultraviolet irradiation unit fixing member 100 is fixed together with the arm portion 19b of the drain pump 19 by the screw 50 into the screw hole 301c of the drain pump fixing member 300. In this way, the ultraviolet irradiation unit fixing member 100 is fixed to the fixing portion 40 together with the drain pump 19. In other words, the ultraviolet irradiation unit fixing member 100 is configured to be "co-fastened" to the fixing portion 40 together with the drain pump 19.

[0057] Furthermore, the drain pump fixing member 300 is provided with a rotation suppression groove 301g and a rotation suppression rib 302g that suppress rotation of the drain pump fixing member 300 at the fixing portion 40 to which the drain pump 19 is fixed. According to this configuration example, rotation of the inner member 301 or the outer member 302 can be suppressed when the inner member 301 and the outer member 302 that constitute the drain pump fixing member 300 are fixed with the screws 303. This facilitates attachment of the inner member 301 and the outer member 302, in other words, attachment of the drain pump fixing member 300.

[0058] As described above, the drain pump fixing member can be implemented by appropriately modifying the structure, shape, etc. of each part. Furthermore, although a description of specific modifications will be omitted, the ultraviolet irradiation unit fixing member 100 can also be implemented by appropriately modifying the structure, shape, etc. of each part.
