- FIG. 11 shows the state of the damper 40 when the ventilation damper fully closed mode is selected. That is, the damper drive mechanism 45 rotates the damper 40, and the cross section n between the guide ventilation ports 43 is formed. The rotation of the damper 40 is stopped at a position facing the end edge of the unit closing vertical portion 20a of the unit base vertical portion 20a.
- All the guide vents 43 are surrounded by the fully closed pieces 24 of the unit base 20 and the ribs 21 and become completely closed. In addition, there is no change in that the secondary ventilation port 25 of the unit base 20 is completely closed by the damper 40 surface.
- the ventilation unit 15 is completely closed by the damper 40, and the wind passage is shut off.
- the ventilation unit 15 intrusion of dust and noise from the outside into the indoor unit 1 and the room can be reliably prevented, and the comfort can be improved.
- the ventilation unit 15 is set to be in the above-described state after the end of the normal air-conditioning operation as well as after the end of the main body cleaning operation mode described above. If this mode is selected during air-conditioning operation, it will be in the same state as normal air-conditioning operation.
- the ventilation unit 15 is arranged inside the heat exchanger 10, the ventilation unit can be installed without increasing the size of the indoor unit 1, saving space and improving ventilation. The noise generated by the operation of the unit 15 can be minimized.
- the ventilation unit 15 since the ventilation unit 15 has a bearing 27 for one of the support shafts Qh of the cross flow fan 13F constituting the indoor blower 13, the number of required parts is reduced. Contribute to cost reduction.
- a second suction formed by the position of the damper 40 The guide section Sb sucks the primary air before passing through the air filter 11 to the heat exchanger 10 so that the amount of dust adhering to the heat exchanger 10 can be suppressed. Minimize heat exchange energy loss, such as when performing ventilation operation in parallel with air conditioning operation.
- the electric dust collector 12 and the ventilation unit 15 are arranged on the opposite sides, the ozone generated by the electric dust collector is filled in the indoor unit main body 1 and the entire unit is spread. After that, ventilation can be done, and sterilization efficiency can be improved.
- a ventilation function is added to improve comfort, and the resulting increase in external dimensions of the main body and increase in noise are suppressed.
- an indoor unit of an air conditioner that can be used is obtained.
