The drive motor 32 is attached to the lower body case 26 by being inserted into the recess 26a with the rotation shaft (axis) directed downward. A gear assembly 31 is attached to the shaft of the drive motor 32 so as to rotate with the shaft. The shaft end of the drive motor 32 is supported by a bearing 30 attached to the holding plate 29. The holding plate 29 is fixed to the lower body case 26 with screws.
　支持台２において、ベース台３３は、矩形状に設けられる。ベース台３３は、円形状の凹部を有する。回転軸３４は、ベース台３３の凹部の中心にネジで固定される。複数の支持台側車輪３５は、ベース台３３の凹部の縁部の内側に沿って取り付けられる。車輪摺動板押さえ３６は、ベース台３３の凹部の縁部の外側に沿ってネジで固定される。ギア３７は、ベース台３３の凹部の縁部の内側に沿って設けられる。 In the support stand 2, the base stand 33 is provided in a rectangular shape.

The plurality of support base side wheels 35 are attached along the inside of the edge of the recess of the base base 33. The wheel sliding plate retainer 36 is fixed with screws along the outside of the edge of the concave portion of the base base 33. The gear 37 is provided along the inside of the edge of the concave portion of the base base 33.
　障害壁３８は、ベース台３３の凹部の底部から上方に突き出す。障害壁３８は、複数のスリットを有する。例えば、障害壁３８は、第１スリット３９ａと第２スリット３９ｂと第３スリット３９ｃを有する。複数のセンサは、下方本体ケース２６の下部に設けられる。複数のセンサは、複数のスリットに対応して設けられる。例えば、複数のセンサは、第１センサ４０ａと第２センサ４０ｂと第３センサ４０ｃからなる。例えば、第１センサ４０ａと第２センサ４０ｂと第３センサ４０ｃとは、フォトインタラプタからなる。 The obstacle wall 38 protrudes upward from the bottom of the recess of the base table 33. The obstacle wall 38 has a plurality of slits. For example, the obstacle wall 38 includes a first slit 39a, a second slit 39b, and a third slit 39c. The plurality of sensors are provided below the lower body case 26. The plurality of sensors are provided corresponding to the plurality of slits.

When the slit is disposed between the first light emitting unit 42a and the first light receiving unit 43a, the first light receiving unit 43a receives light emitted from the first light emitting unit 42a. In this case, the first sensor 40a transmits a Lo signal. The first inverter 44a inverts the Lo signal to a Hi signal. When the obstacle wall 38 is disposed between the first light emitting unit 42a and the first light receiving unit 43a, the first light receiving unit 43a does not receive the light emitted by the first light emitting unit 42a. In this case, the first sensor 40a transmits a Hi signal. The first inverter 44a inverts the Hi signal to the Lo signal.
　例えば、第２センサ４０ｂは、第２発光部４２ｂと第２受光部４３ｂとを備える。スリットが第２発光部４２ｂと第２受光部４３ｂとの間に配置された際、第２受光部４３ｂは、第２発光部４２ｂが発した光を受ける。この場合、第２センサ４０ｂは、Ｌｏ信号を送信する。第２反転器４４ｂは、当該Ｌｏ信号をＨｉ信号に反転させる。障害壁３８が第２発光部４２ｂと第２受光部４３ｂとの間に配置された際、第２受光部４３ｂは、第２発光部４２ｂが発した光を受けない。この場合、第２センサ４０ｂは、Ｈｉ信号を送信する。第２反転器４４ｂは、当該Ｈｉ信号をＬｏ信号に反転させる。 For example, the second sensor 40b includes a second light emitting unit 42b and a second light receiving unit 43b. When the slit is disposed between the second light emitting unit 42b and the second light receiving unit 43b, the second light receiving unit 43b receives the light emitted by the second light emitting unit 42b. In this case, the second sensor 40b transmits a Lo signal. The second inverter 44b inverts the Lo signal to the Hi signal. When the obstacle wall 38 is disposed between the second light emitting unit 42b and the second light receiving unit 43b, the second light receiving unit 43b does not receive the light emitted by the second light emitting unit 42b. In this case, the second sensor 40b transmits a Hi signal. The second inverter 44b inverts the Hi signal to the Lo signal.
　例えば、第３センサ４０ｃは、第３発光部４２ｃと第３受光部４３ｃとを備える。スリットが第３発光部４２ｃと第３受光部４３ｃとの間に配置された際、第３受光部４３ｃは、第３発光部４２ｃが発した光を受ける。この場合、第３センサ４０ｃは、Ｌｏ信号を送信する。第３反転器４４ｃは、当該Ｌｏ信号をＨｉ信号に反転させる。障害壁３８が第３発光部４２ｃと第３受光部４３ｃとの間に配置された際、第３受光部４３ｃは、第３発光部４２ｃが発した光を受けない。この場合、第３センサ４０ｃは、Ｈｉ信号を送信する。第３反転器４４ｃは、当該Ｈｉ信号をＬｏ信号に反転させる。 For example, the third sensor 40c includes a third light emitting unit 42c and a third light receiving unit 43c. When the slit is disposed between the third light emitting unit 42c and the third light receiving unit 43c, the third light receiving unit 43c receives light emitted from the third light emitting unit 42c. In this case, the third sensor 40c transmits a Lo signal. The third inverter 44c inverts the Lo signal to the Hi signal. When the obstacle wall 38 is disposed between the third light emitting unit 42c and the third light receiving unit 43c, the third light receiving unit 43c does not receive the light emitted by the third light emitting unit 42c. In this case, the third sensor 40c transmits a Hi signal. The third inverter 44c inverts the Hi signal to the Lo signal.

FIG. 9 is a diagram for explaining a change in a signal received by the control device for the air purifier according to the first embodiment of the present invention.
　図９に示すように、本体１が２２．５°の角度で左側を向いている際、本体１の停止位置は、第３位置となる。この際、第１ポートは、Ｌｏ信号を受信する。第２ポートは、Ｈｉ信号を受信する。第３ポートは、Ｈｉ信号を受信する。本体１が正面から２２．５°の間の角度で左側を向いている際、本体１の停止位置は、不明となる。この際、第１ポートは、Ｌｏ信号を受信する。第２ポートは、Ｌｏ信号を受信する。第３ポートは、Ｌｏ信号を受信する。本体１が正面を向いている際、本体１の位置は、第４位置となる。この際、第１ポートは、Ｈｉ信号を受信する。第２ポートは、Ｈｉ信号を受信する。第３ポートは、Ｈｉ信号を受信する。 As shown in FIG. 9, when the main body 1 is facing the left side at an angle of 22.5 °, the stop position of the main body 1 is the third position.

　次に、図１０を用いて、本体１が第３位置および第４位置の間から第４位置に移動する際の第１ポートから第３ポートが受信する信号の変化を説明する。
　図１０はこの発明の実施の形態１における空気清浄機の制御装置が受信する信号の変化を説明するための図である。 Next, a change in the signal received by the third port from the first port when the main body 1 moves from between the third position and the fourth position to the fourth position will be described with reference to FIG.
FIG. 10 is a diagram for explaining a change in a signal received by the control device for the air cleaner according to the first embodiment of the present invention.
　図１０に示すように、本体１が正面から２２．５°の間の角度で左側を向いている際、本体１の停止位置は、不明となる。この際、第１ポートは、Ｌｏ信号を受信する。第２ポートは、Ｌｏ信号を受信する。第３ポートは、Ｌｏ信号を受信する。本体１が第４位置に近づく過渡期においては、第１センサ４０ａから第３センサ４０ｃ等の構造的な誤差により、第１ポートから第３ポートのうちのいずれかが先にＨｉ信号を受信する。例えば、第３ポートが先にＨｉ信号を受信する。本体１が正面を向いている際、第１ポートから第３ポートの全てがＨｉ信号を受信する。 As shown in FIG. 10, when the main body 1 is facing the left side at an angle of 22.5 ° from the front, the stop position of the main body 1 is unknown.

　次に、図１１を用いて、本体１の回転方向に関する現在位置の確定方法を説明する。
　図１１はこの発明の実施の形態１における空気清浄機の本体の回転方向に関する現在位置の確定方法を説明するための図である。 Next, a method for determining the current position in the rotation direction of the main body 1 will be described with reference to FIG.
FIG. 11 is a diagram for explaining a method for determining the current position with respect to the rotation direction of the main body of the air cleaner according to the first embodiment of the present invention.
　例えば、図１１に示すように、本体１の回転に伴い第１センサ４０ａが移動すると、第１センサ４０ａの検知範囲における検知開始点αは、第１スリット３９ａに差し掛かる。この時点では、制御装置２４は、本体１の回転方向の現在位置を確定しない。その後、第１センサ４０ａの検知範囲の中心の停止位置βは、第１スリット３９ａの中心と重なる。この時点で、制御装置２４は、本体１の回転方向の現在位置を確定する。 For example, as shown in FIG. 11, when the first sensor 40a moves with the rotation of the main body 1, the detection start point α in the detection range of the first sensor 40a reaches the first slit 39a. At this time, the control device 24 does not determine the current position of the main body 1 in the rotation direction. Thereafter, the stop position β at the center of the detection range of the first sensor 40a overlaps the center of the first slit 39a. At this time, the control device 24 determines the current position of the main body 1 in the rotation direction.
　具体的には、制御装置２４は、第１センサ４０ａの検知範囲における検知開始点αが第１スリット３９ａに差し掛かってから判定時間Ｔ１だけ経過した際に本体１の回転方向の現在位置を確定する。判定時間Ｔ１は、第１スリット３９ａから第３スリット３９ｃの構造的な誤差および第１センサ４０ａから第３センサ４０ｃの構造的な誤差を考慮して予め設定される。 Specifically, the control device 24 determines the current position in the rotation direction of the main body 1 when the determination time T1 has elapsed since the detection start point α in the detection range of the first sensor 40a reaches the first slit 39a. . The determination time T1 is set in advance in consideration of the structural error of the first slit 39a to the third slit 39c and the structural error of the first sensor 40a to the third sensor 40c.
　なお、第１センサ４０ａが逆方向に移動する場合も同様である。第２センサ４０ｂおよび第３センサ４０ｃに関しても同様である。 The same applies when the first sensor 40a moves in the reverse direction. The same applies to the second sensor 40b and the third sensor 40c.

　ステップＳ１では、制御装置２４は、位置データの読み込みを開始する。その後、ステップＳ２に進み、制御装置２４は、位置データを読み込む。具体的には、制御装置２４は、第１ポートから第３ポートの信号の状態を検知する。その後、ステップＳ３に進み、制御装置２４は、位置データが判定時間Ｔ１だけ継続して変化しないか否かを判定する。 In step S1, the control device 24 starts reading position data. Then, it progresses to step S2 and the control apparatus 24 reads position data. Specifically, the control device 24 detects the state of signals from the first port to the third port. Thereafter, the process proceeds to step S3, and the control device 24 determines whether or not the position data continues to change for the determination time T1.
　ステップＳ３で判定時間Ｔ１が経過する前に位置データが変化した場合は、ステップＳ２に戻る。ステップＳ３で位置データが判定時間Ｔ１だけ継続して変化しない場合は、ステップＳ４に進む。ステップＳ４では、制御装置２４は、位置データを確定する。その後、ステップＳ５に進み、制御装置２４は、位置データの読み込みを完了する。 If the position data has changed before the determination time T1 has elapsed in step S3, the process returns to step S2. If the position data does not change continuously for the determination time T1 in step S3, the process proceeds to step S4. In step S4, the control device 24 determines the position data. Thereafter, the process proceeds to step S5, and the control device 24 completes the reading of the position data.
　次に、図１３を用いて、制御装置２４による本体１の回転制御を説明する。
　図１３はこの発明の実施の形態１における空気清浄機の制御装置による本体の回転制御を説明するためのフローチャートである。 Next, rotation control of the main body 1 by the control device 24 will be described with reference to FIG.
FIG. 13 is a flowchart for illustrating the rotation control of the main body by the control device for the air cleaner according to the first embodiment of the present invention.
　ステップＳ１１では、制御装置２４は、本体１の回転制御運転を開始する。その後、ステップＳ１２に進み、制御装置２４は、本体１に対する方向決定処理を行う。具体的には、制御装置２４は、本体１の目標位置を決定する。制御装置２４は、最終的に記憶している位置情報に対応した位置と目標位置に基づいて、本体１の回転方向を決定する。 In step S11, the control device 24 starts the rotation control operation of the main body 1. Then, it progresses to step S12 and the control apparatus 24 performs the direction determination process with respect to the main body 1. FIG. Specifically, the control device 24 determines the target position of the main body 1. The control device 24 determines the rotation direction of the main body 1 based on the position corresponding to the finally stored position information and the target position.
　その後、ステップＳ１３に進み、制御装置２４は、位置データを読み込む。その後、ステップＳ１４に進み、制御装置２４は、位置データが判定時間Ｔ１だけ継続して変化しないか否かを判定する。 Thereafter, the process proceeds to step S13, and the control device 24 reads position data. Thereafter, the process proceeds to step S14, and the control device 24 determines whether or not the position data continues to change for the determination time T1.
　ステップＳ１４で判定時間Ｔ１が経過する前に位置データが変化した場合は、ステップＳ１３に戻る。ステップＳ１４で位置データが判定時間Ｔ１だけ継続して変化しない場合は、ステップＳ１５に進む。ステップＳ１５では、制御装置２４は、位置データを確定する。その後、ステップＳ１６に進み、制御装置２４は、本体１の現在位置が目標位置か否かを判定する。 If the position data has changed before the determination time T1 has elapsed in step S14, the process returns to step S13. If the position data does not change continuously for the determination time T1 in step S14, the process proceeds to step S15. In step S15, the control device 24 determines the position data. Thereafter, the process proceeds to step S16, and the control device 24 determines whether or not the current position of the main body 1 is a target position.
　ステップＳ１６で本体１の現在位置が目標位置でない場合は、ステップＳ１７に進む。ステップＳ１７では、制御装置２４は、駆動モータ３２を駆動する。その結果、本体１は、支持台２に対して回転する。その後、ステップＳ１３からの動作が繰り返される。 If it is determined in step S16 that the current position of the main body 1 is not the target position, the process proceeds to step S17. In step S <b> 17, the control device 24 drives the drive motor 32. As a result, the main body 1 rotates with respect to the support base 2. Thereafter, the operation from step S13 is repeated.
　ステップＳ１６で本体１の現在位置が目標位置の場合は、ステップＳ１８に進む。ステップＳ１８では、制御装置２４は、駆動モータ３２を停止させる。その結果、本体１は、支持台２に対しての回転を停止する。その後、ステップＳ１９に進み、制御装置２４は、回転制御運転を停止する。 If it is determined in step S16 that the current position of the main body 1 is the target position, the process proceeds to step S18. In step S18, the control device 24 stops the drive motor 32. As a result, the main body 1 stops rotating with respect to the support base 2. Then, it progresses to step S19 and the control apparatus 24 stops rotation control driving | operation.
　以上で説明した実施の形態１によれば、本体１の回転方向の現在位置は、複数のセンサによるスリットの検知状態に基づいて検知される。このため、本体１の回転方向の現在位置を把握することができる。 According to the first embodiment described above, the current position in the rotation direction of the main body 1 is detected based on the detection state of the slits by a plurality of sensors. For this reason, the current position in the rotation direction of the main body 1 can be grasped.
　また、本体１の回転方向の現在位置は、複数のセンサによるスリットの検知状態が判定時間Ｔ１だけ継続して変化しない場合に確定される。このため、構造的な誤差による現在位置の誤判定を防止することができる。 Also, the current position in the rotation direction of the main body 1 is determined when the detection state of the slits by the plurality of sensors does not change continuously for the determination time T1. For this reason, erroneous determination of the current position due to structural errors can be prevented.
　また、本体１の回転は、複数のセンサによるスリットの検知状態が判定時間Ｔ１だけ継続して目標位置に対応した状態の場合に停止する。このため、所望の方向に本体１を向けることができる。 Also, the rotation of the main body 1 stops when the slit detection state by the plurality of sensors continues for the determination time T1 and corresponds to the target position. For this reason, the main body 1 can be directed in a desired direction.
　また、３つのセンサで５つの回転方向の位置を検知することができる。このため、検知すべき位置ごとにセンサが配置される場合よりも空気清浄機を安価に製作することができる。 In addition, it is possible to detect the position in five rotational directions with three sensors. For this reason, an air cleaner can be manufactured cheaply compared with the case where a sensor is arrange | positioned for every position which should be detected.

In addition, the same code | symbol is attached | subjected to the same part as Embodiment 1, or an equivalent part. The description of this part is omitted.
　ステップＳ２１では、制御装置２４は、本体１の回転制御運転を開始する。その後、ステップＳ２２に進み、制御装置２４は、本体１に対する方向決定処理を行う。具体的には、制御装置２４は、本体１の目標位置を決定する。 In step S21, the control device 24 starts the rotation control operation of the main body 1. Then, it progresses to step S22 and the control apparatus 24 performs the direction determination process with respect to the main body 1. FIG. Specifically, the control device 24 determines the target position of the main body 1.
　その後、ステップＳ２３に進み、制御装置２４は、位置データを読み込む。その後、ステップＳ２４に進み、制御装置２４は、位置データが判定時間Ｔ１だけ継続して変化しないか否かを判定する。 Thereafter, the process proceeds to step S23, and the control device 24 reads position data. Thereafter, the process proceeds to step S24, and the control device 24 determines whether or not the position data continues to change for the determination time T1.
　ステップＳ２４で判定時間Ｔ１が経過する前に位置データが変化した場合は、ステップＳ２３に戻る。ステップＳ２４で位置データが判定時間Ｔ１だけ継続して変化しない場合は、ステップＳ２５に進む。ステップＳ２５では、制御装置２４は、位置データを確定する。その後、ステップＳ２６に進み、制御装置２４は、本体１の現在位置が目標位置か否かを判定する。 If the position data has changed before the determination time T1 has elapsed in step S24, the process returns to step S23. If the position data does not change continuously for the determination time T1 in step S24, the process proceeds to step S25. In step S25, the control device 24 determines the position data. Thereafter, the process proceeds to step S26, and the control device 24 determines whether or not the current position of the main body 1 is the target position.
　ステップＳ２６で本体１の現在位置が目標位置でない場合は、ステップＳ２７に進む。ステップＳ２７では、制御装置２４は、駆動モータ３２を駆動する。その結果、本体１は、支持台２に対して回転する。その後、ステップＳ２８に進み、制御装置２４は、本体１の回転速度が予め設定された判定速度以上か否かを判定する。例えば、制御装置２４は、本体１の回転速度が２００ＰＰＳ以上か否かを判定する。 If it is determined in step S26 that the current position of the main body 1 is not the target position, the process proceeds to step S27. In step S <b> 27, the control device 24 drives the drive motor 32. As a result, the main body 1 rotates with respect to the support base 2. Then, it progresses to step S28 and the control apparatus 24 determines whether the rotational speed of the main body 1 is more than the preset determination speed. For example, the control device 24 determines whether the rotation speed of the main body 1 is 200 PPS or higher.
　ステップＳ２８で本体１の回転速度が判定速度未満の場合は、ステップＳ２９に進む。ステップＳ２９では、制御装置２４は、判定時間Ｔ１を比較的長い第１基準時間とする。例えば、制御装置２４は、判定時間Ｔ１を６００ｍｓとする。その後、ステップＳ２３からの動作が繰り返される。 If the rotation speed of the main body 1 is less than the determination speed in step S28, the process proceeds to step S29. In step S29, the control device 24 sets the determination time T1 as a relatively long first reference time. For example, the control device 24 sets the determination time T1 to 600 ms. Thereafter, the operation from step S23 is repeated.
　ステップＳ２８で本体１の回転速度が判定速度以上の場合は、ステップＳ３０に進む。ステップＳ３０では、制御装置２４は、判定時間Ｔ１を比較的短い第２基準時間とする。例えば、制御装置２４は、判定時間Ｔ１を３００ｍｓとする。その後、ステップＳ２３からの動作が繰り返される。 If the rotation speed of the main body 1 is equal to or higher than the determination speed in step S28, the process proceeds to step S30. In step S30, the control device 24 sets the determination time T1 as a relatively short second reference time. For example, the control device 24 sets the determination time T1 to 300 ms. Thereafter, the operation from step S23 is repeated.
　ステップＳ２６で本体１の現在位置が目標位置の場合は、ステップＳ３１に進む。ステップＳ３１では、制御装置２４は、駆動モータ３２を停止させる。その結果、本体１は、支持台２に対しての回転を停止する。その後、ステップＳ３２に進み、制御装置２４は、回転制御運転を停止する。 If the current position of the main body 1 is the target position in step S26, the process proceeds to step S31. In step S31, the control device 24 stops the drive motor 32. As a result, the main body 1 stops rotating with respect to the support base 2. Then, it progresses to step S32 and the control apparatus 24 stops rotation control driving | operation.
　以上で説明した実施の形態２によれば、本体１の回転速度が判定速度未満の場合、判定時間Ｔ１は、比較的長い第１基準時間となる。本体１の回転速度が判定速度以上の場合、判定時間Ｔ１は、比較的短い第２基準時間となる。第２基準時間は、第１基準時間よりも短く設定される。このため、本体１の回転方向の現在位置をより正確に把握することができる。 According to the second embodiment described above, when the rotation speed of the main body 1 is less than the determination speed, the determination time T1 is a relatively long first reference time. When the rotation speed of the main body 1 is equal to or higher than the determination speed, the determination time T1 is a relatively short second reference time. The second reference time is set shorter than the first reference time. For this reason, the current position in the rotation direction of the main body 1 can be grasped more accurately.

Then, it progresses to step S42 and the control apparatus 24 performs the direction determination process with respect to the main body 1. FIG. Specifically, the control device 24 determines the target position of the main body 1.
　その後、ステップＳ４３に進み、制御装置２４は、位置データを読み込む。その後、ステップＳ４４に進み、制御装置２４は、位置データが判定時間Ｔ１だけ継続して変化しないか否かを判定する。 Thereafter, the process proceeds to step S43, and the control device 24 reads position data. Thereafter, the process proceeds to step S44, and the control device 24 determines whether or not the position data continues to change for the determination time T1.
　ステップＳ４４で判定時間Ｔ１が経過する前に位置データが変化した場合は、ステップＳ４３に戻る。ステップＳ４４で位置データが判定時間Ｔ１だけ継続して変化しない場合は、ステップＳ４５に進む。ステップＳ４５では、制御装置２４は、本体１の現在位置が確定可能か否かを判定する。 If the position data has changed before the determination time T1 has elapsed in step S44, the process returns to step S43. If the position data does not change continuously for the determination time T1 in step S44, the process proceeds to step S45. In step S45, the control device 24 determines whether or not the current position of the main body 1 can be determined.
　ステップＳ４５で本体１の現在位置が確定しない場合は、ステップＳ４６に進む。ステップＳ４６では、制御装置２４は、駆動モータ３２を駆動する。その結果、本体１は、支持台２に対して回転する。その後、ステップＳ４３からの動作が繰り返される。ステップＳ４５で本体１の現在位置が確定した場合は、ステップＳ４７に進む。ステップＳ４７では、制御装置２４は、本体１の現在位置が目標位置か否かを判定する。 If the current position of the main body 1 is not fixed in step S45, the process proceeds to step S46. In step S <b> 46, the control device 24 drives the drive motor 32. As a result, the main body 1 rotates with respect to the support base 2. Thereafter, the operation from step S43 is repeated. If the current position of the main body 1 is determined in step S45, the process proceeds to step S47. In step S47, the control device 24 determines whether or not the current position of the main body 1 is a target position.
　ステップＳ４７で本体１の現在位置が目標位置でない場合は、ステップＳ４８に進む。ステップＳ４８では、制御装置２４は、駆動モータ３２を駆動する。その結果、本体１は、支持台２に対して回転する。その後、ステップＳ４３からの動作が繰り返される。 If it is determined in step S47 that the current position of the main body 1 is not the target position, the process proceeds to step S48. In step S <b> 48, the control device 24 drives the drive motor 32. As a result, the main body 1 rotates with respect to the support base 2. Thereafter, the operation from step S43 is repeated.
　ステップＳ４７で本体１の現在位置が目標位置の場合は、ステップＳ４９に進む。ステップＳ４９では、制御装置２４は、駆動モータ３２を停止させる。その結果、本体１は、支持台２に対しての回転を停止する。その後、ステップＳ５０に進み、制御装置２４は、回転制御運転を停止する。 If the current position of the main body 1 is the target position in step S47, the process proceeds to step S49. In step S49, the control device 24 stops the drive motor 32. As a result, the main body 1 stops rotating with respect to the support base 2. Then, it progresses to step S50 and the control apparatus 24 stops rotation control driving | operation.
　以上で説明した実施の形態３によれば、本体１の回転方向の現在位置が確定しない場合、制御装置２４は、本体１の回転方向の現在位置が確定するまで支持台２に対して本体１を回転させる。このため、本体１の回転方向の現在位置が不明な場合でも、本体１を所望の方向に向けることができる。例えば、本体１の回転が物理的な障害により抑制された場合でも、本体１を最終的に所望の方向に向けることができる。また、使用者が強制的に本体１を回転させた場合でも、本体１を最終的に所望の方向に向けることができる。 According to the third embodiment described above, when the current position in the rotation direction of the main body 1 is not fixed, the control device 24 controls the main body 1 with respect to the support base 2 until the current position in the rotation direction of the main body 1 is fixed. Rotate. For this reason, even when the current position in the rotation direction of the main body 1 is unknown, the main body 1 can be directed in a desired direction. For example, even when the rotation of the main body 1 is suppressed due to a physical failure, the main body 1 can be finally directed in a desired direction. Even when the user forcibly rotates the main body 1, the main body 1 can be finally directed in a desired direction.
　なお、複数のセンサと複数のスリットとの位置を上下反転させてもよい。すなわち、複数のセンサを支持台２に取り付けて複数のスリットを本体１に設けてもよい。この場合も、本体１の回転方向の現在位置を把握することができる。 It should be noted that the positions of the plurality of sensors and the plurality of slits may be turned upside down. That is, a plurality of sensors may be attached to the support base 2 and a plurality of slits may be provided in the main body 1. Also in this case, the current position in the rotation direction of the main body 1 can be grasped.
　以上のように、この発明に係る空気清浄機は、本体の回転方向の現在位置を把握するシステムに利用できる。 As described above, the air cleaner according to the present invention can be used in a system for grasping the current position in the rotation direction of the main body.
