A switching valve B is provided.

  Next, operations in the air supply mode, the exhaust mode, and the air supply / exhaust mode (simultaneous supply / exhaust operation) by the ventilation unit 20 will be described. When the ventilation unit 20 is selected to the air supply mode by the above selection switch, the exhaust exclusive fan 24 is in a stopped state (OFF), and the operation of the supply / exhaust fan 23 (ON) causes the air supply / exhaust passage 23 to operate. Outdoor air is supplied to the house room through the outdoor air suction path Q and the indoor supply path S, which are air supply paths.

  When the ventilation unit 20 is selected to be in the exhaust mode by the above selection switch, the air in the house room is discharged to the outside by the operation of the exhaust fan 24, and the house room is operated by the operation of the air supply / exhaust fan 23. Is controlled to be discharged to the outside through the indoor air suction path P and the outdoor exhaust path R which are exhaust paths in the supply / exhaust passage.

  This will be described in more detail. In the air supply mode, the flow of air is indicated by arrows in FIGS. 5, 8, and 9. As shown in FIG. 8, the first switching valve A opens the outdoor air inlet 33 and the indoor air inlet 25. 9, the second switching valve B opens the outdoor air supply port 37 and closes the indoor air discharge port 36, as shown in FIG.

  Therefore, when the supply / exhaust fan 23 is operated (ON), outdoor air is sucked from the outdoor air supply pipe 26, passes through the outdoor air suction path Q and the indoor supply path S, and enters the duct 53 from the air supply port 37. Then, it flows through the cover 51 of the ultraviolet lamp device 50 and flows into the air conditioner 1 from the outlet 51A while being sterilized or sterilized by the ultraviolet lamp 52. The outdoor air that has flowed out into the air conditioner 1 is circulated into the house room by the blower 4 in the air conditioner 1.

  Further, in the exhaust mode, the flow of air is shown in FIGS. 6, 10, and 11. As shown in FIG. 10, the first switching valve A closes the outdoor air inlet 33 and the indoor air inlet 25. As shown in FIG. 11, the second switching valve B closes the outdoor air supply port 37 and opens the indoor air discharge port 36. For this reason, the indoor air that has entered the air conditioner 1 due to the operation (ON) of the air supply / exhaust fan 23 is sucked from the indoor air suction port 25 and passes through the indoor air suction path P and the outdoor exhaust path R. The air flows from the air discharge port 36 through the outdoor exhaust pipe 27 and is discharged to the outside. In the exhaust mode, the air in the house room is discharged to the outside by the operation of the exhaust fan 24.

  Further, in the air supply / exhaust mode, outdoor air is supplied to the room through the air supply path of the air supply / exhaust passage by the operation (ON) of the air supply / exhaust fan 23, and the operation of the exhaust exclusive fan (ON). Thus, the indoor air is controlled to be discharged to the outside through the exhaust passage. That is, the first switching valve A opens the outdoor air suction port 33 and closes the indoor air suction port 25. As shown in FIG. 9, the second switching valve B opens the outdoor air supply port 37 and the indoor air. The discharge port 36 is closed.

  Therefore, when the supply / exhaust fan 23 is operated (ON), outdoor air is sucked from the outdoor air supply pipe 26, passes through the outdoor air suction path Q and the indoor supply path S, and enters the duct 53 from the air supply port 37. Then, it flows through the cover 51 of the ultraviolet lamp device 50 and flows into the air conditioner 1 from the outlet 51A while being sterilized or sterilized by the ultraviolet lamp 52. The outdoor air that has flowed out into the air conditioner 1 is circulated into the house room by the blower 4 in the air conditioner 1. At the same time, the air in the house room is discharged to the outside by the operation (ON) of the exhaust fan 24.

  As described above, in the exhaust mode, the indoor exhaust can be quickly performed by the operation (ON) of the supply / exhaust fan 23 and the exhaust dedicated fan 24, which is effective when the indoor air is contaminated.

  In the air supply mode, it is also effective to clean the indoor air by taking in outside air by operating the air supply / exhaust fan 23.

  In the air supply / exhaust mode, air supply and exhaust are simultaneously performed by the operation (ON) of the air supply / exhaust fan 23 and the exhaust exclusive fan 24, so that an indoor air purification promoting effect can be exhibited.

  Since these controls can be achieved by the passage switching by the first switching valve A and the second switching valve B and the operation (ON) of the supply / exhaust fan 23 and the exhaust fan 24, the control is easy and accurate.

The outdoor air supply pipe 26 and the outdoor exhaust pipe 27 are not two pipes as shown in the figure, but a single pipe (pipe) communicating with the outdoor air suction port 33 and the indoor air discharge port 36. If the air supply and exhaust are combined, the pipe extending from the air conditioner 1 to the outside is connected to this one pipe (pipe) and the discharge port 28B that forms the exhaust passage of the exhaust exclusive part 22. Two pipes are used.

  Furthermore, if the pipe connected to the discharge port 28B is omitted and the pipe connected to the discharge port 28B is also used as a single pipe (pipe), the pipe extending from the air conditioner 1 to the outdoor side is It is possible to have only one pipe (pipe).

  The air conditioner of the present invention is not limited to the above embodiment with respect to the form of the air conditioner 1 and the ventilation unit 20, and can be applied to various air conditioners without departing from the technical scope of the present invention. is there.
