AIR CONDITIONER

To prevent fiber waste from accumulating in a comb-tooth of a separation part 43.SOLUTION: An air conditioner includes: a case 11 in which a suction port of air is provided; a filter 31 for preventing intrusion of dust; a drive mechanism 32 for delivering the filter; a cleaning unit for cleaning the filter; a collection box for collecting the dust; and a control part. The cleaning unit includes: a brush 41 for scraping off the dust attached to the surface of the filter 31; a separation part 43 for separating the dust attached to the brush to the collection box side; and a drive motor and a brush motor. The control part includes: a filter cleaning part for actuating the drive motor and the brush motor and executing the cleaning of the filter; and a storage device for storing the number of times of the execution of filter cleaning by the filter cleaning part. When the number of times of the execution of filter cleaning is counted to be equal to or greater than a predetermined number of times X, the filter cleaning part removes the dust in the separation part by performing normal rotation and the reverse rotation of the brush alternately for a plurality of number of times Y.SELECTED DRAWING: Figure 6 【課題】分離部４３のクシ歯に繊維クズが溜まることを防止する。【解決手段】空気の吸込口が設けられたケース１１と、塵埃の侵入を防止するフィルタ３１と、フィルタを送り込む駆動機構３２と、フィルタを清掃する清掃ユニットと、塵埃を集める収集箱と、制御部と、を備え、清掃ユニットにはフィルタ３１表面に付着している塵埃を掻きとるブラシ４１と、ブラシに付着した塵埃を収集箱側へ離脱させる分離部４３と、駆動モータとブラシモータと、を有し、制御部には、駆動モータとブラシモータを作動してフィルタの清掃を実施するフィルタ清掃部と、フィルタ清掃部によるフィルタの清掃の実施回数を記憶する記憶装置と、を備え、フィルタ清掃部は、フィルタの清掃の実施回数を所定回数Ｘ以上カウントしたときに、ブラシの逆回転と正回転を交互に複数回Ｙ行なうことで分離部の塵埃を取り除くようにした。【選択図】 図６
