　図４は、クリーン処理における第１の実施形態の制御例を示すタイミングチャートである。図４（ａ）は、室内機２の状態を示し、図４（ｂ）は、送風機モータ２３１とイオン発生電源５４のタイミングチャートである。
　第１の実施形態の制御例では、風向変更板２５１により吹出口２１２が閉じられた状態において、イオン発生部５が動作され、イオンが筐体２１の内部に充満する。なお、図４（ｂ）において、横軸Ｔは時間軸を示す。 [Clean processing of the first embodiment]
FIG. 4 is a timing chart showing a control example of the first embodiment in the clean process. FIG. 4A shows a state of the indoor unit 2, and FIG. 4B is a timing chart of the blower motor 231 and the ion generating power source 54.
In the control example of the first embodiment, the ion generating unit 5 is operated in a state where the air outlet 212 is closed by the wind direction changing plate 251, and the ions fill the inside of the housing 21. In FIG. 4B, the horizontal axis T indicates the time axis.
　時間軸に沿って説明すると、時間Ｔ１０に、暖房運転停止操作が行われた場合、制御部６は、風向変更板２５１が吹出口２１２を閉じるように、風向調整モータ２５２を制御するとともに、送風機モータ２３１及びイオン発生電源５４をＯＦＦ状態とする。ＯＦＦ状態は、時間Ｔ１０から時間Ｔ１１の期間Ｐ１０の間、継続される。
　時間Ｔ１１では、送風機モータ２３１をＯＦＦ状態としたまま、イオン発生電源５４をＯＮ状態として、イオンを発生させる。イオン発生電源５４は、時間Ｔ１２において、ＯＦＦ状態とされる。時間Ｔ１１から時間Ｔ１２までの期間Ｐ１１において、筐体２１の内部でイオンが発生する。 Explaining along the time axis, when the heating operation stop operation is performed at the time T10, the control unit 6 controls the wind direction adjusting motor 252 so that the wind direction changing plate 251 closes the air outlet 212, and also blows the blower. The motor 231 and the ion generation power supply 54 are turned off. The OFF state is continued during the period P10 from the time T10 to the time T11.
At time T11, ions are generated by turning on the ion generation power supply 54 while keeping the blower motor 231 in the OFF state. The ion generation power supply 54 is turned off at time T12. During the period P11 from the time T11 to the time T12, ions are generated inside the housing 21.
　期間Ｐ１１は、風向変更板２５１が吹出口２１２を閉じているので、筐体２１の内部にイオンが充満する。したがって、期間Ｐ１１では、送風機２３、熱交換器２４、風路２１３、及びフィルタ２２に付着した油とイオンが反応する。
　暖房運転が停止された後に、イオンを筐体２１の内部に充満させるので、油がイオンとの反応が増大しやすい温度帯域で、イオンと接触することによって、油とイオンとを効率的に反応させることができる。
　イオン発生部５で、イオンを発生させる場合、イオン風が発生する。
　したがって、このイオン風により、筐体２１の内部に弱い空気の流れが生じる。よって、送風機２３が停止しても、イオンを含む空気を送風機２３、熱交換器２４、風路２１３、及びフィルタ２２に供給できる。 During the period P11, since the wind direction changing plate 251 closes the air outlet 212, the inside of the housing 21 is filled with ions. Therefore, in the period P11, the oil and ions adhering to the blower 23, the heat exchanger 24, the air passage 213, and the filter 22 react.
Since the ions are filled inside the housing 21 after the heating operation is stopped, the oil reacts efficiently with the ions by contacting the ions in a temperature range in which the reaction with the ions tends to increase. Can be made to.
When the ion generation unit 5 generates ions, an ion wind is generated.
Therefore, this ionic wind causes a weak air flow inside the housing 21. Therefore, even if the blower 23 is stopped, air containing ions can be supplied to the blower 23, the heat exchanger 24, the air passage 213, and the filter 22.
　以上説明したように、本実施形態においては、放電により水を解離してイオンを発生させるイオン発生部５と、吸気口２１１から吸い込んだ空気を吹出口２１２に送る送風機２３と、吸気口２１１から吸い込んだ空気と熱を交換する熱交換器２４と、吹出口２１２から吹き出す空気の方向を調整する風向調整部２５と、送風機２３、熱交換器２４及びイオン発生部５を収容する筐体２１と、制御部６と、を備え、制御部６は、暖房運転停止後に、イオンを筐体２１の内部に充満させるように、送風機２３、風向調整部２５、及びイオン発生部５を制御してもよい。
　この構成によれば、空気調和機の筐体の内部に付着した油とイオンとを反応させることにより、筐体の内部に付着した油を削減することができる。また、油を削減することによって、油による臭いも低減することができる。 As described above, in the present embodiment, the ion generating unit 5 that dissociates water by discharge to generate ions, the blower 23 that sends the air sucked from the intake port 211 to the air outlet 212, and the intake port 211 A heat exchanger 24 that exchanges heat with the sucked air, a wind direction adjusting unit 25 that adjusts the direction of the air blown out from the air outlet 212, and a housing 21 that houses the blower 23, the heat exchanger 24, and the ion generating unit 5. The control unit 6 may control the blower 23, the wind direction adjusting unit 25, and the ion generating unit 5 so as to fill the inside of the housing 21 with ions after the heating operation is stopped. good.
According to this configuration, the oil adhering to the inside of the housing can be reduced by reacting the oil adhering to the inside of the housing of the air conditioner with the ions. Further, by reducing the amount of oil, the odor caused by the oil can also be reduced.
　制御部６は、暖房運転停止後に、送風機２３を停止し、風向調整部２５で吹出口２１２を閉じ、イオン発生部５を動作させてもよい。
　この構成によれば、送風機２３を停止して筐体２１の内部にイオンを充満させるので、送風機２３を動作させる場合と比べて、作動音を低減できる。 After the heating operation is stopped, the control unit 6 may stop the blower 23, close the air outlet 212 at the wind direction adjusting unit 25, and operate the ion generating unit 5.
According to this configuration, since the blower 23 is stopped and the inside of the housing 21 is filled with ions, the operating noise can be reduced as compared with the case where the blower 23 is operated.

In this control example, the air containing the ions blown out from the outlet 212 by the wind direction changing plate 251 is sucked into the intake port 211, so to speak, as a shortcut, and the ions are filled inside the housing 21.
　時間軸に沿って説明すると、暖房運転停止の操作が行われた時間Ｔ２０に、制御部６は、送風機モータ２３１及びイオン発生電源５４をＯＦＦ状態とする。
　時間Ｔ２１では、送風機モータ２３１をＯＮ状態とし、イオン発生電源５４をＯＮ状態として、イオンを発生させる。このときには、風向変更板２５１が最も上向きになるように、風向調整モータ２５２が制御される。時間Ｔ２２では、送風機モータ２３１及びイオン発生電源５４がＯＦＦ状態とされる。 Explaining along the time axis, the control unit 6 turns off the blower motor 231 and the ion generation power supply 54 at the time T20 when the operation of stopping the heating operation is performed.
At time T21, the blower motor 231 is turned on and the ion generating power source 54 is turned on to generate ions. At this time, the wind direction adjusting motor 252 is controlled so that the wind direction changing plate 251 faces most upward. At time T22, the blower motor 231 and the ion generating power supply 54 are turned off.
　第２の実施形態では、制御部６は、時間Ｔ２１から時間Ｔ２２までの期間Ｐ２１において、イオン発生部５をＯＮ状態とし、送風機２３をＯＮ状態とし、風向変更板２５１が最も上向きになるように、風向調整部２５を動作させ、吹出口２１２から吹き出されるイオンを含む空気が、図５（ａ）に矢印で示すように、ショートカットして吸気口２１１に吸い込まれるように、イオン送出運転が行われる。
　イオン送出運転が行われると、イオンが、筐体２１の内部に循環される。このため、送風機２３、熱交換器２４、風路２１３、及びフィルタ２２に付着した油とイオンを効率的に反応させることができる。 In the second embodiment, the control unit 6 turns on the ion generating unit 5 and turns on the blower 23 during the period P21 from the time T21 to the time T22 so that the wind direction changing plate 251 is most upward. , The wind direction adjusting unit 25 is operated, and the ion sending operation is performed so that the air containing the ions blown out from the outlet 212 is sucked into the intake port 211 by a shortcut as shown by the arrow in FIG. 5 (a). Will be done.
When the ion delivery operation is performed, the ions are circulated inside the housing 21. Therefore, the oil and ions adhering to the blower 23, the heat exchanger 24, the air passage 213, and the filter 22 can be efficiently reacted.

Then, the first ion delivery operation is performed. During the period P31 from the time T31 to the time T32, this ion sending operation continues, and during the period P31, the blower motor 231 is driven at a low speed.
　時間Ｔ３２に至ると、空気調和装置の暖房運転（加熱運転）が開始される。
　イオン発生電源５４はＯＦＦ状態となり、イオンの発生が停止されるとともに、送風機モータ２３１が低速で駆動される。送風機２３を低速で動作させながら暖房運転を行うことにより、熱交換器２４に付着する水分を蒸発させるとともに、筐体２１の内部をイオンと油との反応が増大する温度に加熱する。この状態は、時間Ｔ３２から時間Ｔ３３までの期間Ｐ３２、継続される。 When the time T32 is reached, the heating operation (heating operation) of the air conditioner is started.
The ion generation power supply 54 is turned off, the generation of ions is stopped, and the blower motor 231 is driven at a low speed. By performing the heating operation while operating the blower 23 at a low speed, the moisture adhering to the heat exchanger 24 is evaporated and the inside of the housing 21 is heated to a temperature at which the reaction between ions and oil increases. This state continues for a period P32 from time T32 to time T33.
　時間Ｔ３３に至ると、空気調和装置の暖房運転（加熱運転）が停止され、イオン発生電源５４がＯＮ状態となり、イオンが発生し、かつ、吹出口２１２から吹き出される空気が、ショートカットして吸気口２１１に吸い込まれるように、風向調整モータ２５２が制御され、２回目のイオン送出運転が行われる。送風機モータ２３１が駆動される。２回目のイオン送出運転は、時間Ｔ３３から時間Ｔ３４までの期間Ｐ３３、継続されて、冷房運転後のクリーン処理が終了する。 When the time T33 is reached, the heating operation (heating operation) of the air conditioner is stopped, the ion generation power supply 54 is turned on, ions are generated, and the air blown out from the outlet 212 is taken in as a shortcut.
