[0028] An embodiment of an indoor unit of an air conditioner will be described below with reference to the drawings. Figure 1 The indoor unit 10 of the illustrated air conditioner is an indoor unit that is buried in a ceiling of a room that is an air-conditioned space, a so-called ceiling-buried indoor unit. The indoor unit 10 is provided with a casing 11 and a decorative panel 12. The casing 11 is inserted from the indoor side into a rectangular opening portion, not shown, provided in the ceiling. Also, the casing 11 is fixed to the back surface of the ceiling in a suspended state by a suspension bolt, not shown, or the like. The decorative panel 12 is installed below the casing 11 in a state of protruding toward the indoor side.

[0029] The decorative panel 12 is formed in a substantially rectangular plate shape. An air intake port 13 that takes in air from the room and an air blowout port 14 that blows out air to the room are provided in the decorative panel 12. The air intake port 13 is formed in a substantially square shape in a central portion of the decorative panel 12. The air intake port 13 is configured as a so-called intake grille that is opened in a lattice shape in a manner that allows air to pass through. The air blowout port 14 is formed as a long opening along each side of the air intake port 13. A louver 14a that adjusts the direction of wind blown out from the air blowout port 14 is provided in the air blowout port 14 in a manner that allows rotation.

[0030] As Figure 2 The casing 11 forms the outer contour of the upper surface and the side surface in the indoor unit 10, for example. The casing 11 is in the shape of a box type having a side surface wall portion, an upper surface wall portion, and a lower surface opening portion. The side surface wall portion of the casing 11 is provided in a wall shape in a manner that closes the side surface of the casing 11. The upper surface wall portion of the casing 11 is provided in a wall shape in a manner that closes the upper surface of the casing 11. The lower surface opening portion of the casing 11 is opened in a substantially rectangular shape in a manner that opens the lower surface of the casing 11. The decorative panel 12 covers the lower surface opening portion of the casing 11 from below. A blower fan 15, a heat exchanger 16, and the like are housed in the casing 11.

[0031] A blower 15 is disposed in the central part of the housing 11. The blower 15 is also disposed above the air intake 13. A heat exchanger 16 is disposed around the blower 15. The heat exchanger 16 is also disposed above the air intake 13 and air outlet 14 in the decorative panel 12. The heat exchanger 16, together with a compressor (not shown) and an outdoor heat exchanger, constitutes a known refrigeration cycle capable of heating and cooling the air.

[0032] like Figure 2 As shown by the dashed arrow W, the indoor unit 10 draws in indoor air through the air intake 13 by driving the fan 15, exchanges heat with the drawn-in air through the heat exchanger 16, and blows the heat-exchanged air out through the air outlet 14. Thus, the indoor unit 10 can perform air conditioning control to adjust the indoor temperature to a predetermined set temperature.

[0033] Additionally, the indoor unit 10 includes a drain tray 17 within its housing 11. The drain tray 17 is positioned between the decorative panel 12 and the heat exchanger 16. The drain tray 17 is arranged to fill the upper portion between the air intake 13 and the air outlet 14. The drain tray 17 receives drainage generated from the heat exchanger 16 below it. The drainage received by the drain tray 17 accumulates within it.

[0034] Additionally, the indoor unit 10 includes a heat insulation component 18 within the housing 11. The heat insulation component 18 is formed, for example, of a material with heat insulation properties such as expanded polystyrene. Like the housing 11, the heat insulation component 18 has a box-shaped form with side walls, an upper surface wall, and a lower surface opening. The side walls of the heat insulation component 18 are configured as walls to close the sides of the heat insulation component 18. The upper surface wall of the heat insulation component 18 is configured as a wall to close the upper surface of the heat insulation component 18. The lower surface opening of the heat insulation component 18 is a generally rectangular opening that opens the lower surface of the heat insulation component 18.

[0035] With the heat insulation member 18 disposed within the housing 11, the outer surface of the side wall of the heat insulation member 18 is arranged along the inner surface of the side wall of the housing 11. Furthermore, with the heat insulation member 18 disposed within the housing 11, the outer surface of the upper surface wall of the heat insulation member 18 is arranged along the inner surface of the upper surface wall of the housing 11. Additionally, with the heat insulation member 18 disposed within the housing 11, the lower surface opening of the heat insulation member 18 is disposed inside the lower surface opening of the housing 11.

[0036] Additionally, the indoor unit 10 includes a drain pump 19 for discharging water accumulated in the drain pan 17 to the outside of the unit. Also... Figure 3As exemplified, a portion of the drain pan 17 located below the drain pump 19 is provided with a water storage portion 17a recessed downward. A water suction port 19a provided at a lower end of the drain pump 19 enters the water storage portion 17a, whereby water suction based on the drain pump 19 can be smoothly performed.

[0037] In addition, as Figure 4 、 Figure 5 、 Figure 6 Exemplarily, the indoor unit 10 is provided with an ultraviolet irradiation device 20 as an example of an ultraviolet irradiation portion. The ultraviolet irradiation device 20 is provided with, for example, a light emitting source capable of emitting ultraviolet rays such as an ultraviolet LED (Light Emitting Diode), a substrate or the like that controls light emission from the light emitting source, and is configured to be capable of irradiating ultraviolet rays toward the drain pan 17, particularly the water storage portion 17a. In addition, the indoor unit 10 is provided with an ultraviolet irradiation portion fixing member 100 for fixing the ultraviolet irradiation device 20.

[0038] As Figure 7 Exemplarily, the ultraviolet irradiation portion fixing member 100 integrally includes a common fastening portion 101 that is fixed, that is, fastened, together with the drain pump 19, and an ultraviolet irradiation portion fixing portion 102 that fixes the ultraviolet irradiation device 20.

[0039] The common fastening portion 101 extends toward the drain pump 19 side. In addition, both end portions of the common fastening portion 101 further extend toward the drain pump 19 side, and have screw holes 101a.

[0040] The ultraviolet irradiation portion fixing portion 102 has a housing portion 102a that houses the ultraviolet irradiation device 20, a housing portion fixing portion 102b that fixes the housing portion 102a, and a linking portion 102c that links the housing portion 102a and the housing portion fixing portion 102b. A hinge portion 102d as a thin-walled portion is interposed between the housing portion fixing portion 102b and the linking portion 102c, and the ultraviolet irradiation portion fixing portion 102 integrally includes the housing portion 102a, the housing portion fixing portion 102b, and the linking portion 102c.

[0041] As Figure 8 Exemplarily, an irradiation port 102e is provided in the housing portion 102a. The ultraviolet irradiation device 20 is a control substrate on which an ultraviolet LED is mounted, and as Figure 7 Exemplarily, the ultraviolet irradiation device 20 is housed in the housing portion 102a in a manner such that the irradiation port 102e opposes the ultraviolet LED, and is fixed to the housing portion 102a by a screw 102f.

[0042] As Figure 7As shown, the fixing part 102b is inclined toward the common fastening part 101. In addition, locking walls 102g are formed at both ends of the fixing part 102b to engage with the side surfaces of the receiving part 102a. Locking holes 102i are formed in the locking walls 102g to engage with the locking claws 102h provided on the side surfaces of the receiving part 102a.

[0043] like Figure 8 As illustrated, by bending the receiving portion 102a and the connecting portion 102c via the hinge portion 102d, the locking claw 102h engages with the locking hole 102i, and the receiving portion 102a is closed by the fixing portion 102b.

[0044] The ultraviolet irradiation device 20, fixed to the ultraviolet irradiation unit fixing part 102, is tilted so that the irradiation port 102e for irradiating ultraviolet light points towards the water storage part 17a of the drain pan 17. Thus, the ultraviolet irradiation device 20 is configured to irradiate ultraviolet light toward the water storage part 17a.

[0045] Furthermore, the ultraviolet irradiation section fixing member 100 also integrally includes a float switch fixing member 103. The float switch fixing member 103 is provided on the side of the ultraviolet irradiation section fixing member 102. In addition, a holding hole 103a for holding the float switch 21 is formed in the float switch fixing member 103. In addition, a slit 103b continuous with the holding hole 103a is formed in the float switch fixing member 103.

[0046] The float switch 21 is an example of a water level sensing unit used to sense the water level in the drain pan 17, and includes a switch body 21a and a retaining post 21b. The float switch 21 is inserted into the retaining hole 103a through the retaining post 21b and is fixed to the float switch fixing part 103 by a nut or the like.

[0047] In addition, such as Figure 9 As illustrated, the ultraviolet irradiation device 20, fixed to the ultraviolet irradiation unit fixing member 100, is positioned higher than the upper limit of the sensing range H of the float switch 21 and lower than the upper end 17b of the drain pan 17. Furthermore, the sensing range H of the float switch 21 defines the range of water levels that can be sensed by the float switch 21. The float switch 21 switches from an open state to a closed state when the water level in the drain pan 17 is outside the sensing range H, and switches from a closed state to an open state when the water level in the drain pan 17 is within the sensing range H.

[0048] Figure 10The control device 30 is configured, for example, with a microcomputer as a main body, and is capable of controlling the overall operation of the indoor unit 10 based on a control program, setting data, and the like. The control device 30 causes the indoor unit 10 to operate based on a control program, setting data, and the like in a case where the float switch 21 is in an off state, that is, in a case where the water level in the drain pan 17 is lower than the lower limit of the sensing range H. However, the control device 30 stops the operation of the indoor unit 10 when the float switch 21 is switched from the off state to the on state. That is, the control device 30 stops the operation of the indoor unit 10 in a case where the water level in the drain pan 17 is within the sensing range H of the float switch 21. Thereby, heat exchange by the heat exchanger 16 is no longer performed, and no drain water is generated, so it is possible to suppress the water level in the drain pan 17 from further rising, and it is possible to avoid the ultraviolet irradiation device 20 from being submerged in water. In addition, it is possible to avoid water from overflowing from the drain pan 17.

[0049] In addition, the control device 30 can perform stirring control in the irradiation of ultraviolet rays by the ultraviolet irradiation device 20. As Figure 11 In the example, the stirring control is control that alternately switches the drain pump 19 between an operating state and a stopped state in the irradiation of ultraviolet rays by the ultraviolet irradiation device 20. Thereby, the period during which the water in the water storage portion 17a of the drain pan 17 is sucked into the drain pump 19 and the period during which the water is returned from the drain pump 19 into the water storage portion 17a of the drain pan 17 are alternately repeated, and it is possible to stir the water in the water storage portion 17a of the drain pan 17. Thereby, it is possible to irradiate ultraviolet rays to the water in the drain pan 17 without omission, and it is possible to effectively suppress the proliferation of microorganisms.

[0050] In addition, as Figure 12 In the example, the fixing portion 40 that fixes the drain pump 19 is provided at a corner portion in the heat insulating member 18. In addition, the fixing portion 40 is formed in a stepped shape or a shelf shape at the corner portion in the heat insulating member 18. Furthermore, the drain pump fixing member 200 for fixing the drain pump 19 is attached to this fixing portion 40.

[0051] As Figure 13 In the example, 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 portion 201a. In addition, the inner member 201 has a plurality of, in this case, three, extension portions 201b that extend radially and outwardly from the inner member main body portion 201a. Threaded holes 201c are formed at the front ends of the extension portions 201b, respectively.

[0052] Two of the plurality of extensions 201b are each formed with a threaded hole 201c. In addition, one of the plurality of extensions 201b is formed with a plurality, in this case two, of threaded holes 201c. In addition, the inner member 201 is provided with a positioning portion 201d extending from the inner member main body portion 201a. The positioning portion 201d is formed in a rectangular shape.

[0053] In addition, as Figure 14 As an example, a locking claw 201e is formed in a central portion of the inner member main body portion 201a. The locking claw 201e extends toward the outer member 202 side. In addition, the locking claw 201e has two front end portions that are elastically deformable in the radial direction of the inner member 201. In addition, the inner member 201 is provided with a plurality, in this case two, of screw receiving portions 201f that are disposed across the locking claw 201e.

[0054] On the other hand, as Figure 13 As an example, the fixing portion 40 on the heat insulating member 18 side is formed with an insertion groove portion 41 into which the inner member 201 is inserted. The insertion groove portion 41 has an insertion groove portion main body 41a into which the inner member main body portion 201a of the inner member 201 is inserted, an extension groove portion 41b into which the extension portion 201b of the inner member 201 is inserted, and a positioning groove portion 41d into which the positioning portion 201d of the inner member 201 is inserted.

[0055] In addition, a through hole 41e through which the locking claw 201e of the inner member 201 is inserted is formed in a central portion of the insertion groove portion 41. In addition, a plurality, in this case two, of through holes 41f through which the screw receiving portions 201f of the inner member 201 are inserted are formed in the insertion groove portion 41.

[0056] In addition, the outer member 202 is provided with a locking hole 202b in a central portion of a rectangular plate-shaped outer member main body portion 202a. In addition, the outer member 202 is provided with a plurality, in this case two, of threaded holes 202c that are disposed across the locking hole 202b.

[0057] As Figure 15 As an example, the drain pump fixing member 200 is installed in a state in which the fixing portion 40 is sandwiched by the inner member 201 and the outer member 202. In the state in which the fixing portion 40 is sandwiched by the inner member 201 and the outer member 202, the locking claw 201e of the inner member 201 is locked to the locking hole 202b of the outer member 202 by the through hole 41e. Thus, the inner member 201 and the outer member 202 are temporarily fixed in a state in which the fixing portion 40 is sandwiched. Also, the inner member 201 and the outer member 202 across the fixing portion 40 are fixed by Figure 13The example screw 203 is fixed by being screwed into the screw receiving portion 201f through the threaded hole 202c. In this way, the inner member 201 and the outer member 202 are fixed in a state of sandwiching the fixed portion 40.

[0058] As described above, the drain pump 19 can be fixed to the drain pump fixing member 200 fixed to the fixed portion 40. That is, as Figure 6 For example, the plurality of arm portions 19b of the drain pump 19 are fixed to the threaded holes 201c of the drain pump fixing member 200 by the screws 50, respectively. In this way, the drain pump 19 is firmly fixed to the fixed portion 40.

[0059] In addition, the above-described ultraviolet irradiation portion fixing member 100 can be fixed to the fixed portion 40 together with the drain pump 19. That is, the common fastening portion 101 of the ultraviolet irradiation portion fixing member 100 is fixed to the threaded holes 201c of the drain pump fixing member 200 together with the arm portions 19b of the drain pump 19 by the screws 50. In this way, the ultraviolet irradiation portion fixing member 100 is fixed to the fixed portion 40 together with the drain pump 19. That is, the ultraviolet irradiation portion fixing member 100 can be so-called "commonly fastened" to the fixed portion 40 together with the drain pump 19.

[0060] When, for example, microorganisms such as bacteria, yeast, and mold multiply and generate a mucous substance, a substance called so-called drain sludge, or the like in the water accumulated in the drain pan 17, there is a concern that the substance clogs the drain pump 19. In particular, in the portion of the drain pan 17 located below the drain pump 19, a recessed water storage portion 17a is provided in order to make the suction of water by the drain pump 19 smooth, but in the refrigeration season, the state in which water is accumulated in the water storage portion 17a is easily maintained, and thus there is a problem in that drain sludge is easily generated, and further, the drain pump 19 is easily clogged. Therefore, it is considered that the multiplication of microorganisms is suppressed by irradiating ultraviolet rays to such a water storage portion 17a, and thus generation of drain sludge in the water storage portion 17a is prevented. The present embodiment relates to an air-conditioner indoor unit 10 provided with an ultraviolet irradiation device 20 that irradiates ultraviolet rays to a water storage portion 17a provided in a portion of a drain pan 17 located below a drain pump 19, and provides a technical solution capable of compactly arranging the ultraviolet irradiation device 20 together with the drain pump 19. According to the above-described example air-conditioner indoor unit 10, the ultraviolet irradiation portion fixing member 100 that fixes the ultraviolet irradiation device 20 is fixed to the fixed portion 40 that fixes the drain pump 19 together with the drain pump 19. According to this configuration example, the ultraviolet irradiation device 20 can be compactly arranged together with the drain pump 19.

[0061] In addition, the drain pump 19 mounted in the indoor unit 10 is designed to be mountable in a plurality of models. That is, the drain pump 19 is designed to be common to a plurality of models. Therefore, the ultraviolet irradiation portion fixing member 100 designed to be able to fix a certain drain pump 19 can be used in other models as well, and thus, it is not necessary to change the design of the ultraviolet irradiation portion fixing member 100 for each model.

[0062] In addition, according to the indoor unit 10, the ultraviolet irradiation portion fixing member 100 can also fix a float switch 21 that senses the water level in the drain pan 17. According to this configuration example, it is not necessary to additionally provide a member for fixing the float switch 21 other than the ultraviolet irradiation portion fixing member 100, and it is possible to suppress an increase in the number of members.

[0063] In addition, according to the indoor unit 10, the control device 30 can perform control to switch the drain pump 19 to an operating state and a stopped state in the irradiation of ultraviolet rays by the ultraviolet irradiation device 20. According to this control example, it is possible to irradiate ultraviolet rays while stirring the water in the water storage portion 17a of the drain pan 17, and it is possible to effectively suppress the proliferation of microorganisms.

[0064] In addition, according to the indoor unit 10, the ultraviolet irradiation device 20 is fixed to the ultraviolet irradiation portion fixing member 100, and thus, is disposed at a position higher than the upper limit of the sensing range H of the float switch 21 and at a position lower than the upper end 17b of the drain pan 17. According to this configuration example, it is possible to avoid the ultraviolet irradiation device 20 from being submerged in the water in the drain pan 17, and in addition, it is also possible to avoid water from overflowing from the drain pan 17.

[0065] In addition, the present embodiment relates to an indoor unit 10 of an air conditioner that has a drain pump 19 that discharges water accumulated in a drain pan 17, and provides a technical solution that can fix the drain pump 19 by inexpensive configuration. According to the indoor unit 10, a drain pump fixing member 200 is installed in a state of sandwiching a fixing portion 40 that fixes the drain pump 19. According to this configuration example, it is possible to fix the drain pump 19 even without embedding a metal plate or the like having a threaded hole into the thermal insulation member 18, and it is possible to fix the drain pump 19 by inexpensive configuration.

[0066] Furthermore, the present embodiment is not limited to the above-described embodiment, and various modifications, extensions, and the like can be made within the scope of the gist thereof.

[0067] For example, in Figure 16 and Figure 17A modification of the drain pump fixing portion is shown in FIG. 6. That is, the drain pump fixing member 300 is configured by combining the inner member 301 and the outer member 302. The inner member 301 has a circular inner member main body portion 301a. In addition, the inner member 301 has a plurality of, in this case three, extension portions 301b extending radially from the inner member main body portion 301a. Threaded holes 301c are formed at the front ends of the extension portions 301b, respectively. In addition, the inner member 301 has a positioning portion 301d extending radially from the inner member main body portion 301a. The positioning portion 301d is formed in a rectangular shape.

[0068] In addition, a threaded hole 301e is formed in the center of the inner member main body portion 301a so as to be open in a circular shape. In addition, a plurality of, in this case two, locking holes 301f are formed in the inner member main body portion 301a so as to sandwich the threaded hole 301e. The locking holes 301f are open in a rectangular shape.

[0069] On the other hand, the fixing portion 40 on the heat insulating member 18 side is formed with an insertion groove portion 341 into which the inner member 301 is inserted. The insertion groove portion 341 has an insertion groove portion main body portion 341a into which the inner member main body portion 301a of the inner member 301 is inserted, an extension groove portion 341b into which the extension portion 301b of the inner member 301 is inserted, and a positioning groove portion 341d into which the positioning portion 301d of the inner member 301 is inserted.

[0070] In addition, a threaded hole 341e corresponding to the threaded hole 301e of the inner member 301 is formed in the center of the insertion groove portion 341. In addition, a plurality of, in this case two, insertion holes 341f are formed in the insertion groove portion 341 so as to sandwich the threaded hole 341e. The insertion holes 341f are open in a rectangular shape corresponding to the locking holes 301f of the inner member 301.

[0071] In addition, the outer member 302 has a screw receiving portion 302b in the center of the circular outer member main body portion 302a. In addition, the outer member 302 has a plurality of, in this case two, locking claws 302c. The locking claws 302c extend from the outer peripheral portion of the outer member main body portion 302a toward the inner member 301 side. In addition, the outer member main body portion 302a is disposed at positions facing each other with the screw receiving portion 302b interposed therebetween. In addition, the locking claws 302c are elastically deformable in the radial direction of the outer member 302.

[0072] The drain pump fixing member 300 is installed in a state of sandwiching the fixing portion 40 by the inner member 301 and the outer member 302. In the state of sandwiching the fixing portion 40 by the inner member 301 and the outer member 302, the locking claw 302c of the outer member 302 is locked to the locking hole 301f of the inner member 301 through the insertion hole 341f. Thus, the inner member 301 and the outer member 302 are temporarily fixed in the state of sandwiching the fixing portion 40. Further, the inner member 301 and the outer member 302 sandwiching the fixing portion 40 are fixed by screwing the screw 303 into the screw receiving portion 302b through the threaded hole 301e and the threaded hole 341e. Thus, the inner member 301 and the outer member 302 are fixed in the state of sandwiching the fixing portion 40.

[0073] Further, as Figure 17 For example, the inner member 301 has a rotation suppression groove 301g in a part of the threaded hole 301e. On the other hand, the outer member 302 has a rotation suppression rib 302g in a part of the screw receiving portion 302b. The rotation suppression groove 301g and the rotation suppression rib 302g each extend in the direction of extension of the screw receiving portion 302b, that is, the axial direction of the drain pump fixing member 300.

[0074] In the state of combining the inner member 301 and the outer member 302 with the fixing portion 40 interposed therebetween, the rotation suppression rib 302g of the outer member 302 is fitted into the rotation suppression groove 301g of the inner member 301. Thus, when the screw 303 is screwed into the screw receiving portion 302b, the inner member 301 can be suppressed from rotating with respect to the outer member 302, or the outer member 302 can be suppressed from rotating with respect to the inner member 301. The rotation suppression groove 301g and the rotation suppression rib 302g function as an example of a rotation suppression portion that suppresses the drain pump fixing member 300 from rotating with respect to the fixing portion 40 that fixes the drain pump 19, or the inner member 301 or the outer member 302 that constitutes the drain pump fixing member 300 from rotating.

[0075] As described above, the drain pump 19 can be fixed to the drain pump fixing member 300 fixed to the fixing portion 40. That is, the arm portions 19b of the drain pump 19 are fixed to the threaded holes 301c of the drain pump fixing member 200 by the screws 50, respectively. Thus, the drain pump 19 is firmly fixed to the fixing portion 40.

[0076] In addition, the ultraviolet irradiation section fixing member 100 described above can also be fixed to the fixing section 40 together with the drain pump 19. That is, the common fastening section 101 of the ultraviolet irradiation section fixing member 100 is fixed to the screw hole 301c of the drain pump fixing member 300 together with the arm section 19b of the drain pump 19 by the screw 50. Thus, the ultraviolet irradiation section fixing member 100 is fixed to the fixing section 40 together with the drain pump 19. That is, the ultraviolet irradiation section fixing member 100 is so-called "commonly fastened" to the fixing section 40 together with the drain pump 19.

[0077] In addition, according to the drain pump fixing member 300, the fixing section 40 that fixes the drain pump 19 is provided with a rotation suppression groove 301g and a rotation suppression rib 302g that suppress rotation of the drain pump fixing member 300. According to this configuration example, when the inner member 301 and the outer member 302 that configure the drain pump fixing member 300 are fixed by the screw 303, rotation of the inner member 301 or the outer member 302 can be suppressed. Thus, installation of the inner member 301 and the outer member 302, in other words, installation of the drain pump fixing member 300 can be easily performed.

[0078] As described above, the drain pump fixing member can be implemented by appropriately changing the configuration, shape, and the like of each section. In addition, although a description of a specific modification example is omitted, the ultraviolet irradiation section fixing member 100 can also be implemented by appropriately changing the configuration, shape, and the like of each section.

[0079] The embodiments of the present application have been described above, but these embodiments are merely suggested as an example, and are not intended to limit the scope of the application. These new embodiments can be implemented in other various ways, and various omissions, substitutions, changes, and the like can be made within the scope of the gist of the application. The present embodiments and modifications thereof are included in the scope, gist of the application, and are included in the scope of the application and equivalents thereof recited in the claims.
