For example, a combination of an air cleaning function and a dehumidifying function, a combination of an air cleaning function and a humidifying function, and a combination of a dehumidifying function and a humidifying function.

  FIG. 1 is a perspective view of an air conditioner 1 according to an embodiment of the present invention.

  In the air conditioner 1, the blower 2, the dehumidifying unit 3, the humidifying unit 4, the air cleaning unit 5 and the control unit 6 are accommodated in the main body 10. In the main body 10, the dehumidifying region is located upstream of the humidifying region with respect to the air flow path A. However, the dehumidifying region may be located downstream of the humidifying region with respect to the air flow path A. This is because, when the humidification operation is switched to the dehumidification operation, even if the air passing through the humidification unit 4 absorbs moisture remaining in the humidification unit 4, the air passes through the dehumidification unit 3 so that the dehumidification is ensured. This is because the released air can be released. Furthermore, in this embodiment, a caster (not shown) is provided on the lower surface of the main body 10 (a surface facing the indoor floor surface) so that the user can easily move the air conditioner 1. Yes. The dehumidifying unit 3 is an example of a dehumidifier.

FIG. 2 is a perspective view of the humidifying unit 4.

  The humidification unit 4 includes a water storage container 40, a vaporizing element 41, a water wheel 42, and a drive unit 43. The water storage container 40 is a water source of moisture given to the air passing through the air flow path A, and is housed in the main body 1 so as to be removable. If the water in the water storage container 40 is insufficient, the user pulls out the water storage container 40 from the outlet 12 of the main body 10 and replenishes the water storage container 40 with water. In the air conditioner of this embodiment, the water captured by the dehumidifying unit 3 is stored in the water storage container 40 to reduce the number of times of water replenishment.

  The vaporizing element 41 is a vaporizing member that is formed into a disk shape with a non-woven fabric and evaporates the water sent from the water storage container 40 by rotating. The vaporizing element 41 has a first gear 411 on the outer periphery, and the first gear 411 is rotated by the drive unit 43. Since the vaporizing element 41 is disposed above the water level when the water storage container 40 is full, the vaporizing element 41 is not in direct contact with the water in the water storage container 40.

  FIG. 3 is a perspective view of the humidifying unit 4 viewed from the downstream side of the air flow path A of FIG.

  The water wheel 42 is rotatably supported by a bearing 40 a of the water storage container 40, and pumps up water in the water storage container 40 and discharges it toward the vaporizing element 41.

  Further, as shown in FIG. 1, the water storage container 40 can be taken out from the outlet 12 of the main body 10 by pulling out the pull-out type first door 10a. Thereby, the user can take out the main body water storage container 40 and supply water and wash the water wheel 42.

  Further, the vaporizing element 41 can be taken out from the outlet 13 of the main body 10 by opening the rotary second door 10b. As a result, the user can take out the vaporizing element 41 and replace it.

  In addition, the excess and deficiency of the water in the said water storage container 40 can be visually confirmed from the window part 10c provided in the 1st door 10a. More specifically, the window portion 10c is a rectangular hole, and a convex portion 40c (see FIG. 3) formed in advance in the water storage container 40 is fitted in the hole. The user can visually check the water level reflected on the convex portion 40c from the hole of the window portion 10c.

  As shown in FIGS. 2 and 3, the vaporizing element 41 is formed in a shape that does not project the rotating shaft in order to facilitate removal from the main body 10. For this reason, the vaporizing element 41 is supported by the first gear 411 meshing with the drive gear 431 and the second gear 423. In order for the first gear 411 to maintain a stable posture, the drive gear 431 and the second gear 423 are disposed below the rotation axis of the first gear 411 and are relative to the vertical center line of the vaporizing element 41. Are arranged on opposite sides. Thereby, the vaporizing element 41 can rotate stably even if it is not supported by the shaft, and when it is taken out from the main body 10, there is no protruding shaft, so that it can be easily taken out without being caught inside the main body 10.

The circulation fan 33 is an example of a blower.

  The heat exchange unit 32 includes a first duct 35, a second duct 36, and a condenser 37. In the heat exchange part 32, when the circulation fan 33 is operating, the air from the unit main body 31 flows along the dotted arrow. More specifically, the air that has exited from the unit main body 31 flows through the first duct 35, then flows through the second duct 36 via the condenser 37, and returns to the unit main body 31. At this time, moisture in the air that has come out of the unit main body 31 is condensed by the condenser 37, so that low-humidity air can flow into the second duct 36. In addition, the condensed water passes through a predetermined outlet and drops into a water storage container 40 described later.

  The condenser 37 has a plurality of metal tubes 37a. The space in the first duct 35 communicates with the space in the second duct 36 through the plurality of metal tubes 37a, 37a,. Further, the plurality of metal tubes 37a, 37a,... Are arranged at a predetermined interval from each other. Further, part of the air in the air flow path A passes around the plurality of metal tubes 37a, 37a,..., And cools the plurality of metal tubes 37a, 37a,. Thereby, the high-temperature air that has entered the plurality of metal pipes 37a, 37a,... From the first duct 35 is cooled, and condensed water is generated. Note that another part of the air in the air flow path A passes through the dehumidification rotor 34.

  FIG. 5 is an exploded perspective view of the dehumidifying unit 3 viewed from the upstream side of the air flow path A. FIG.

  The unit main body 31 is fixed to the heat exchanging portion 32 with a plurality of screws 38, 38,. At this time, in order to circulate the air blown out by the circulation fan 33, the upstream end of the first duct 35 is connected to the downstream end of the unit body 31 (the end opposite to the circulation fan 33). Connecting. The downstream end of the second duct 36 is connected to the circulation fan 33 so as to face the suction port 33a.

  FIG. 6 is an exploded perspective view of the unit main body 31 viewed from the upstream side of the air flow path A. FIG.

  In addition to the circulation fan 33 and the dehumidifying rotor 34, the unit main body 31 includes a heater unit 301, a frame 302, a chamber 303, a chamber cover 304, a thermistor 305, a temperature fuse 306, and a sensor cover 307. The heater 301 and the chamber 303 are an example of a housing. The heater unit 301 is also an example of a heating unit.

  The heater unit 301 heats the air from the circulation fan 33. The heated high-temperature air passes through a substantially fan-shaped region of the dehumidifying rotor 34 facing the air outlet 301a of the heater unit 301 and absorbs moisture in the region. The circulation fan 33 is fixed to the frame 302 with screws 39A, and the heater section 301 is fixed to the chamber 303 with screws 39B and 39C.

  The frame 302 is formed so as to cover approximately three-quarters of the peripheral edge of the dehumidifying rotor 34 and not to cover substantially the entire end surface opposite to the heater portion 301. In addition, a pinion gear 308 and a drive motor 309 that drives the pinion gear 308 are attached to the frame 302. Further, the dehumidifying rotor 34 is rotatably attached to the frame 302 by screws 39C.

  The chamber 303 and the chamber cover 304 guide high-humidity air from the dehumidification rotor 34 to the upstream end of the first duct 35. The chamber cover 304 is fixed to the chamber 303 with screws 39D.

  The thermistor 305 detects the temperature of air guided to the first duct 35 by the chamber 303 and the chamber cover 304.

  The thermal fuse 306 is blown when the ambient temperature rises and reaches a predetermined set temperature. As a result, the power supply to the heater unit 301 is stopped, and air heating from the circulation fan 33 toward the dehumidifying rotor 34 is not performed.

  The sensor cover 307 is fixed to the chamber 303 with screws 39E and covers the thermistor 305 and the thermal fuse 306.

  FIG. 7 is an exploded perspective view of the dehumidifying rotor 34 viewed from the upstream side of the air flow path A. FIG.

  The dehumidifying rotor 34 includes a dehumidifying element 51, a metal holding plate 52 for holding the dehumidifying element 51, a resin driven gear 53 for rotationally driving the holding plate 52 and the dehumidifying element 51, and a holding plate. And a resin-made central core 54 which is connected and fixed to the screw 52 with a screw 55A. The holding plate 52 is an example of a holding unit, and the driven gear 53 is an example of a gear member.

  The dehumidifying element 51 is a honeycomb structure, and is formed into a disk shape and a porous shape by a material kneaded by mixing zeolite powder, a binder, and an expansion agent. The binder is selected from thermoplastic resins such as modified PPE (polyphenylene ether), polypropylene, polystyrene, and ABS (acrylonitrile butadiene styrene) resin. The expansion agent expands at the time of forming the honeycomb structure and forms innumerable bubbles. For this reason, the dehumidification element 51 has high adsorptivity with respect to moisture.

  A holding plate 52 is coupled and fixed to the driven gear 53 with screws 55B. The driven gear 53 meshes with the pinion gear 308 when the dehumidifying rotor 34 is attached to the frame 302. Thereby, the driving force of the drive motor 309 is transmitted to the driven gear 53 via the pinion gear 308, so that the dehumidifying element 51, the holding plate 52 and the central core 54 can rotate together with the driven gear 53.

  The central core 54 is closely fitted in a substantially cylindrical space inside the dehumidifying element 51 in the radial direction. At this time, the rib 54 a formed on the outer peripheral surface of the central core 54 bites into the inner peripheral surface of the dehumidifying element 51 and prevents the dehumidifying element 51 from rotating with respect to the central core 54.

  FIG. 8A is a front view of the holding plate 52 viewed from the upstream side of the air flow path A. FIG. FIG. 8B is a top view of the holding plate 52. Moreover, FIG. 8C is sectional drawing seen from CC line of FIG. 8A. FIG. 8D is a side view of the holding plate 52.

  As shown in FIGS. 8A to 8D, the holding plate 52 includes a boss portion 61, an annular disc portion 62, an arm portion 63, and a reinforcing portion 64.

  The boss portion 61 is formed so that a part thereof protrudes to the downstream side of the air flow path A from the arm portion 63. A part of the boss portion 61 has a through hole 65, and a protrusion 54 b (see FIG. 7) of the center core 54 is fitted into the through hole 65. A plurality of through holes 66 are provided around the through hole 65 at a phase interval of 60 degrees. The shaft portion of the screw 55 </ b> A is inserted into each through hole 66.

  The annular disc portion 62 is connected and fixed to the driven gear 53 with a screw 55B. The annular disc part 62 is disposed so as to surround the boss part 61 and is connected to the boss part 61 via a plurality of arm parts 63. More specifically, the ring-shaped disc part 62 includes a bottom part 621 and a side wall part 622. The bottom 621 is provided so as to be substantially parallel to the upstream end surface of the dehumidifying element 51. On the other hand, the side wall part 622 is provided so as to be continuous with the outer peripheral edge part of the bottom part 621 and to be substantially perpendicular to the bottom part 621.

  The ring-shaped disc portion 62 includes a plurality of screwing portions 623, and the circumferential interval between the screwing portions 623 is approximately 60 degrees. Each screwing portion 623 is for connecting and fixing the annular disc portion 62 to the driven gear 53 with a screw 55B. For this reason, each screwing portion 623 has a through hole 624 through which the shaft portion of the screw 55B is inserted.

  The plurality of arm portions 63 extend radially from the boss portion 61 toward the annular disc portion 62. Each arm part 63 is connected to another arm part 63 via a substantially arc-shaped reinforcing part 64.

  A plurality of first slits 625 are provided on the side wall portion 622 of the annular disc portion 62 so that the phase overlaps the arm portion 63. Each first slit 625 extends in a direction substantially parallel to the rotation axis of the dehumidifying element 34. In addition, each first slit 625 is provided such that the width on the bottom portion 621 side is narrower than the width on the heater portion 301 side (the side opposite to the bottom portion 621 side). The end of each first slit 625 on the bottom 621 side has a substantially arc shape.

  Furthermore, a plurality of second slits 626 are provided on the side wall portion 622 of the annular disc portion 62 so as to be adjacent to the screwing portion 623. Each second slit 626 extends in a direction inclined with respect to the rotation axis of the dehumidifying element 34. Each of the second slits 626 is provided so that the width on the back side (the bottom portion 621 side) is narrower than the width on the distal end side (the side opposite to the bottom portion 621 side) of the screwing portion 623. The end on the back side of each second slit 626 has a substantially arc shape.

  As shown in FIG. 1, a selection panel 11 for selecting an air cleaning operation, a dehumidifying operation, and a humidifying operation is provided on the uppermost surface of the main body 10 and connected to the control unit 6. The selection panel 11 includes a selection button 37 capable of selecting rotation and stop of the dehumidification rotor 34. When the selection button 37 is turned off during the dehumidification operation, the rotation of the dehumidification rotor 34 is stopped and dehumidification is stopped. At this time, since the heater unit 301 and the circulation fan 33 are operating, the high-temperature air flows through the first duct 35 and the second duct 36 and circulates. For this reason, since the air which passes the air flow path A is warmed when passing the heat exchange part 35, small-scale heating is performed. At this time, the humidification unit 4 is operated at the same time to perform the heating / humidification operation. In the present embodiment, the heating / humidifying operation mode is set in advance in the control unit 6 so that the heating / humidifying operation can be selected from the selection panel 11.

  According to the air conditioner having the above configuration, the dehumidification rotor 34 rotates in accordance with the operation of the drive motor 309 during the dehumidifying operation. And the area | region which is not covered with the chamber 303 in the dehumidification element 51 contacts the air which passes the air flow path A, and adsorb | sucks a water | moisture content. This region is opposed to the heater unit 301 by the rotation of the dehumidifying rotor 34 after moisture is adsorbed. At this time, the high-temperature air heated by the heater unit 301 passes through the region where the moisture is adsorbed. Thereby, the area | region which adsorb | sucked the said water | moisture content discharge | releases a water | moisture content, can contact the air which passes the air flow path A again, and can adsorb | suck a water | moisture content.

  As described above, since moisture is repeatedly adsorbed and released in the dehumidifying element 51, the air passing through the air flow path A can be continuously dehumidified.

  Further, in the dehumidifying unit 3, since the first slit 625 and the second slit 626 are provided in the ring-shaped disc portion 62 of the holding plate 52, when the holding plate 52 is formed by, for example, drawing processing, Warpage can be prevented from occurring.

  Therefore, the contact of the dehumidification rotor 34 with the heater unit 301 and the chamber 303 can be reduced, and the rotation of the dehumidification rotor 34 can be prevented from being hindered by the heater unit 301 and the chamber 303.

  Further, since the warpage of the holding plate 52 can be prevented, as shown in FIG. 9, the clearance C1 between the heater section 301 and the dehumidification rotor 34 and the clearance C2 between the chamber 303 and the dehumidification rotor 34 are reduced. it can.

  Therefore, it is possible to prevent the high-temperature air heated by the heater unit 301 from passing through the clearances C1 and C2 and flowing into the chamber 303, so that it is possible to prevent the dehumidification capability from being lowered.

  In addition, since the first slit 625 is provided so that the phase overlaps the arm portion 63, a decrease in strength of the holding plate 52 can be suppressed.

  Further, since the second slit 626 is provided so as to be adjacent to the screwing portion 623, warping of the screwing 623 can be prevented.

  Further, since the second slit 626 is provided so that the width on the back side is narrower than the width on the tip side of the screwing portion 623, the holding plate 52 can be kept small while reducing the strength of the holding plate 52. 52 warpage can be prevented.

  In the above embodiment, the number of the first slits 625 and the plurality of second slits 626 is plural, but may be singular.

  In the above embodiment, the plurality of first slits 625 are provided in the side wall 622 of the ring-shaped disc portion 62 so that the phase overlaps the arm portion 63, but the plurality of first slits so that the phase overlaps the arm portion 63. A slit may be provided.

  In the above embodiment, the first slit 625 and the second slit 626 are provided on the side wall portion 622 of the annular disc portion 62, but may be provided on the bottom portion 621 of the annular disc portion 62.

  In the above embodiment, instead of the condenser 37, for example, a condenser having a Peltier element may be used.
