Summary:PROBLEM TO BE SOLVED: To suppress heat generation of a switching element, while reducing noise due to the switching operation of the switching element as much as possible.SOLUTION: A control computer 30 switches from a first drive mode to a second drive mode, upon receiving the information that the temperature detected by a temperature sensor 31 rose and reached a first set temperature. The control computer 30 switches from the second drive mode to a third drive mode, upon receiving the information that the temperature detected by the temperature sensor 31 rose and reached a second set temperature higher than the first set temperature. 【課題】スイッチング素子のスイッチング動作に起因した騒音を極力小さくしつつも、スイッチング素子の発熱を抑制すること。【解決手段】制御コンピュータ３０は、前記温度センサ３１により検出された温度が上昇し第１設定温度に達した旨の情報を得たときに第１駆動モードから第２駆動モードに切り換える。また、制御コンピュータ３０は、温度センサ３１により検出された温度が上昇し第１設定温度よりも高い第２設定温度に達した旨の情報を得たときに第２駆動モードから第３駆動モードに切り換える。【選択図】図２
