  When air passes through the humidifying filter 520, the moisture adsorbed on the humidifying filter 520 evaporates to become moist air and flows to the third region 330 along the humidified air flow path 540. After moisture is adsorbed by the adsorbent in the third region 330, the dried air again flows to the humidifying filter 520 by the third blower 510. As described above, the humidified air channel 540 may be configured as a closed channel.

  A water supply pipe 570 provided with the water supply valve 550 may be connected to supply tap water. The drain pipe 580 provided with the drain valve 560 is connected to the outside of the air conditioner so that the water in the water tank 530 can be drained to the outside.

Heat is exchanged with room air flowing through 110.

  The room air whose temperature has been increased by heating in the first heat supply unit 150 is exhausted into the room through the outlet 110c of the first air flow path 110, thereby heating the room.

  The air cleaning mode will be described with reference to FIG.

  In the air cleaning mode, the first blower 160 is turned on (On), and the direction changing gate 450 of the flow path changing unit 400 is set to the first position as in the heating mode. In this case, the rotor member 300 may be configured not to rotate.

  The indoor air that has flowed in through the inlet 110a of the first air flow path 110 due to the operation of the first air blower 160 is subjected to primary filtration of foreign particles having large particles by the free filter 120, and harmful effects such as allergies by the functional filter 130. Then, the fine particles are removed by the HEPA filter 140.

  The room air that has passed through the HEPA filter 140 passes through the first region 310 and is then discharged into the room through the outlet 110c of the first air flow path 110, thereby cleaning the room air.

  The dehumidifying mode will be described with reference to FIG.

  When the dehumidifying mode is activated, the first blower 160, the second blower 260, and the second heat supply unit 250 are turned on, and the rotor member 300 rotates. In this case, the direction changing gate 450 of the flow path changing unit 400 is set to the first position as in the humidifying mode.

  When the first blower 160 is operated, the indoor air that has flowed into the first air flow path 110 passes through the first region 310 of the rotor member 300 via the plurality of filters 120, 130, and 140 and is included in the indoor air. Moisture is adsorbed by the adsorbent in the first region 310. The room air from which moisture has been removed in the first region 310 is discharged into the room through the outlet 110c of the first air flow path 110.

  When the second blower 260 is operated, outdoor air that has flowed in through the inlet 210a of the second air passage 210 passes through the free filter 220, the medium filter 230, the second inlet 420, and the second outlet 440 in sequence. Then, it flows to the second heat supply unit 250.

  The hot water supply valve 251 is opened to heat the outdoor air in the second heat supply unit 250, and the hot water supplied through the hot water supply pipe 152 and the hot water supply valve 251 passes through the second heat supply unit 250 in the second air flow path. Heat exchange is performed with outdoor air flowing through 210.

  The outdoor air heated while passing through the second heat supply unit 250 passes through the second region 320 of the rotor member 300. When the adsorbent of the rotor member 300 that has adsorbed the moisture in the room air in the first region 310 rotates and is positioned in the second region 320, the moisture in the adsorbent is evaporated by the heated outdoor air passing through the second region 320. The outdoor air is in a moist air state and is discharged to the outside through the outlet 210c of the second air flow path 210.

  By such a process, the indoor air is dehumidified and a comfortable indoor environment can be maintained.

  The ventilation mode will be described with reference to FIG.

  When the ventilation mode is activated, the first blower 160 and the second blower 260 are activated. In this case, the direction change gate 450 of the flow path switching unit 400 is in the second position by connecting the first inlet 410 and the second outlet 440, and connecting the second inlet 420 and the second outlet 440. Is set as follows.

  The room air sucked into the inlet 110a of the first air passage 110 by the operation of the second blower 260 passes through the free filter 120, the first inlet 410 and the second outlet 440 of the passage changer 400, and the rotor. After passing through the second region 320 of the member 300, it is discharged to the outside through the outlet portion 210c of the second air flow path 210.

  At the same time, the outdoor air sucked into the inlet portion 210a of the second air flow path 210 by the operation of the first blower 160 is connected to the free filter 220, the medium filter 230, the second inlet 420 of the flow path changing section 400 and the second air inlet 420a. The first exhaust port 430, the functional filter 130, and the HEPA filter 140 are sequentially passed through the first region 310 of the rotor member 300, and then discharged into the room through the outlet 110 c of the first air flow path 110.

  Through such a process, the indoor air is discharged to the outside, and the outdoor air flows into the room through the plurality of filters 220, 230, 130, and 140, thereby ventilating the room air.

  If the flow path switching unit 400 is configured to switch the flow path as described above, outdoor air is filtered by the free filter 220 and the medium filter 230 provided in the second air flow path 210 in the ventilation mode. The functional filter 130 and the HEPA filter 140 provided in the first air flow path 110 are also filtered, that is, a number of filters 220, 230, 130 provided in the first air flow path 110 and the second air flow path 210. Since it flows through the room after being filtered through 140, clean air can be supplied to the room.

  In addition, the functional filter 130 and the HEPA filter 140 not only filter indoor air flowing through the inlet 110a of the first air flow path 110 in the humidifying mode, heating mode, air cleaning mode, and dehumidifying mode, but also in the ventilation mode. Since the outdoor air flowing in through the inlet portion 210a of the two air flow path 210 is also filtered, it is not necessary to separately provide a filter for filtering the indoor air and the outdoor air.

  According to the above configuration, by providing the flow path switching unit 400 at the point where the flow paths 110 and 210 of the indoor air and the outdoor air intersect, the humidity adjustment, heating, air cleaning, and ventilation modes can be achieved with a simple structure.
