A sirocco fan driven by an electric motor is provided in the casing. Therefore, when the sirocco fan is driven by an electric motor, air is sucked from the suction port 19a and air sucked from the discharge port 19b is discharged.
[0037]
  Moreover, as shown in FIG. 8 which is a sectional view taken along the line VIII-VIII in FIG. 2, a duct 20 is provided in the suction port 19 a of the ventilation device 19. The duct 20 has a substantially L shape in a plan view, and has openings at both ends thereof and at substantially central portions of both ends.
  These openings are the first opening 21 that opens toward the front side of the air conditioning indoor unit 10, that is, toward the suction grille 11, and the front side of the indoor heat exchanger 13, that is, the suction grille 11 and the indoor heat exchanger. 13, in other words, a second opening 22 that opens toward the allergen deactivation filter 18, and a third opening 23 that opens toward the suction port 19 a of the ventilation device 19. .
  The first opening 21 is provided with a damper (flow path switching mechanism) 24. The damper 24 closes the first opening 21 (FIG. 8A), opens the first opening 21, and communicates the second opening 22 and the third opening 23. Can take two positions (FIG. 8A).
  The position of the damper 24 can be changed by a known mechanism such as a link mechanism or a two-position motor.
[0038]
  With this configuration, when the damper 24 takes the position shown in FIG. 8A, the second opening 22 and the third opening 23 are communicated with each other, and thereby the air in the air conditioning indoor unit 10 is communicated. Thus, a flow path (second discharge path) C2 that leads to the suction port 19a of the ventilation device 19 is formed.
  On the other hand, when the damper 24 takes the position shown in FIG. 8B, the first opening 21 and the third opening 23 are communicated with each other, and the second opening 22 and the third opening 23 are connected. Communication is blocked, thereby forming a flow path (first discharge path) C1 that guides indoor air to the suction port 19a of the ventilation device 19.
[0039]
  FIG. 9 is a schematic configuration diagram of an air conditioner 100 including the indoor unit 10 for air conditioning.
  In FIG. 9, reference numeral 30 denotes an air conditioning outdoor unit. The outdoor unit 30 for air conditioning includes a compressor 31 for compressing refrigerant, an outdoor heat exchanger 32 for performing heat exchange between the refrigerant and outdoor air, and refrigerant and outdoor air in the outdoor heat exchanger 32. It has the outdoor fan 33 which accelerates | stimulates heat exchange with.
  Reference numeral 50 denotes a refrigerant pipe for connecting the air conditioning indoor unit 10 and the air conditioning outdoor unit 30 and circulating the refrigerant between the air conditioning indoor unit 10 and the air conditioning outdoor unit 30.
  Reference numeral 60 denotes a remote controller (remote controller), which can set the operating state of the air conditioner 100.
[0040]
  In FIG. 9, reference numeral 70 denotes a ventilation hose, one end of which is connected to the outlet 19 b of the ventilator 19 and the other end is disposed outside the room.
  Thereby, the air which passed the ventilation apparatus 19 will be discharged | emitted outside.
[0041]
  In the air conditioner 100 including the air conditioning indoor unit 10 configured as described above, the air conditioner 100 is provided in the duct 20 during the heating operation performed to inactivate the allergen captured by the allergen deactivation filter. The damper 24 takes the position shown in FIG. 8A, that is, closes the first opening 21 and communicates the second opening 22 and the third opening 23, and the ventilation device 19 operates. It is supposed to be.
[0042]
  Thereby, warm air around the heat exchanger heated to inactivate the allergen captured by the allergen deactivation filter can be discharged to the outside through the duct 20 and the ventilation device 19, for example, in summer Even when the air conditioner 100 is heated to inactivate the allergen trapped by the allergen deactivation filter during cooling, the warm air around the indoor heat exchanger is prevented from leaking into the room. be able to.
[0043]
  Moreover, even if the allergen captured by the allergen deactivation filter is removed from the filter by heating, the allergen is again discharged by the duct 20 and the ventilator 19 so that the allergen is discharged again. It is possible to reliably prevent returning to the room.
[0044]
  On the other hand, in the air conditioner 100 including the air conditioning indoor unit 10 configured as described above, when performing a ventilation operation for discharging indoor air to the outside, the damper 24 provided in the duct 20 is shown in FIG. , Ie, the position where the communication between the second opening 22 and the third opening 23 is blocked, the position where the first opening 21 and the third opening 23 are communicated, and the ventilation device 19. Is now working.
[0045]
  Thereby, indoor air can be discharged | emitted outside through the duct 20 and the ventilation apparatus 19. FIG. That is, harmful gases such as carbon dioxide generated by human breathing and formaldehyde generated from building materials and wallpaper can be discharged to the outside.
[0046]
  As shown in FIG. 1, the allergen deactivation filter 18 is provided in the vicinity of the indoor heat exchanger 13, that is, on the upstream side of the air flow path.
  Thereby, the relative humidity of the allergen deactivation filter 18 can be efficiently increased by the condensed water generated in the indoor heat exchanger 13.
  Moreover, the heat of the heated indoor heat exchanger 13 can be efficiently transmitted to the allergen deactivation filter 18.
[0047]
  Furthermore, since the second opening 22 of the duct 20 opens toward the upstream side of the air flow path of the indoor heat exchanger 13, the air flow when heating the allergen deactivation filter 18 is influenced by the indoor heat. It will go to the allergen deactivation filter 18 from the exchanger 13, and the allergen deactivation filter 18 can be heated more efficiently.
[0048]
  As a recent research result, when the above-mentioned allergen deactivation filter 18 is given moisture (moisture) so that the relative humidity becomes 80% or more, and the allergen deactivation filter 18 is heated at 40 ° C. or more for about 30 minutes. The result that the inactivation rate of allergen exceeds 80% is obtained.
  Therefore, in the allergen removal operation mode, it is most effective if the allergen deactivation filter is operated in such a state in the above-described air conditioning indoor unit and air conditioner.
[0049]
  The allergen removal operation is not enabled only during the summer cooling operation (or dehumidification operation) as described above, and can also be operated during the winter heating operation.
  During heating operation in winter, low-capacity cooling operation is performed in order to increase the relative humidity of the allergen deactivation filter 18 to, for example, 80% or more. At this time, in order to prevent the cold air around the indoor heat exchanger from leaking into the room, it is preferable to place the damper 24 in FIG.
  After the relative humidity (moisture) necessary for the enzyme of the filter to be effective is ensured by the cooling operation, the indoor heat exchanger is heated to 40 ° C. or higher again as the heating operation.
  Thereby, the allergen caught by the allergen inactivation filter 18 can be inactivated.
[0050]
  Further, if this air conditioner 100 is used, it is possible to capture and inactivate allergens in the room even in spring and autumn.
  That is, the air conditioner 100 is blown to capture allergens present in the room by the allergen deactivation filter 18.
  Next, in order to increase the relative humidity of the allergen deactivation filter 18 to be, for example, 80% or more, a low-performance cooling operation is performed. At this time, in order to prevent the cold air around the indoor heat exchanger from leaking into the room, it is preferable to place the damper 24 in FIG.
  After the relative humidity (moisture) necessary for the enzyme of the filter to be effective is ensured by the cooling operation, the indoor heat exchanger is heated to 40 ° C. or higher again as the heating operation. Also at this time, in order to prevent the warm air around the indoor heat exchanger from leaking into the room, it is preferable to place the damper 24 in FIG.
  Thereby, the allergen caught by the allergen inactivation filter 18 can be inactivated.
[0051]
  As described above, by using the indoor unit for air conditioning according to the present invention and the air conditioner equipped with the indoor unit, it is possible to remove and inactivate allergens in the room throughout the year, and uncomfortable air that does not suit the season Can be prevented from being released.
[0052]
  Furthermore, in the embodiment described above, the allergen deactivation filter 18 is disposed only in the indoor heat exchanger 13, but the present invention is not limited to this, and the indoor heat exchanger 14 and / or the indoor heat exchange is not limited thereto. It can also be arranged on the upstream side of the air flow path of the vessel 15.
[0053]
  Furthermore, the duct 20 described with reference to FIGS. 2, 8, and 9 is not limited to this, and the first opening 21 is closed by the wall surface and does not have the damper 24. It may be a thing. That is, as shown in FIG. 8 (a), it has the second opening 22 and the third opening 23, and thereby the indoor air that has passed through the prefilter 25 and the air in the air conditioning indoor unit 10 May be a duct in which only a flow path (second discharge path) C2 leading to the suction port 19a of the ventilation device 19 is formed. In other words, a duct that opens to a position where the indoor air that has passed through the prefilter 25 and the air in the air conditioning indoor unit 10 can be sucked may be disposed in the suction port 19 a of the ventilation device 19.
  Thus, the manufacturing cost can be reduced by omitting the first opening 21 and the damper 24.
[0054]
