ここで、部屋の室温は、部屋の中で均一ではないこともある。例えば、部屋の天井付近と床付近では温度差が大きい場合が有り、また、部屋にキッチンが設置されていればコンロ付近が高温となる。また、エアコンからの冷風を撹拌させたい場合には、扇風機がエアコンと併用されるが、エアコンの吹き出し口は部屋の他の空間と比べて低温である。従って、部屋の室温を測定しても、部屋の状況によっては適切な風を得ることができない場合があった。 Here, the room temperature may not be uniform within the room. For example, there may be a large temperature difference between the vicinity of the ceiling and the vicinity of the floor of a room, and if a kitchen is installed in the room, the temperature near the stove becomes high. Also, when it is desired to stir the cold air from the air conditioner, a fan is used together with the air conditioner, but the temperature of the air outlet of the air conditioner is lower than that of other spaces in the room. Therefore, even if the room temperature of the room is measured, it may not be possible to obtain an appropriate wind depending on the conditions of the room.

本発明は、部屋の状況に応じて適切な風を発生させることができる扇風機を提供する。 SUMMARY OF THE INVENTION The present invention provides an electric fan capable of generating an appropriate wind according to the conditions of a room.

本発明によれば、部屋の状況に応じて適切な風を発生させることができる扇風機を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the electric fan which can generate an appropriate wind according to the condition of a room can be provided.

次に、図に基づいて、本発明の実施形態を説明する。図１に示す扇風機１は、ベース部２を備える。ベース部２は、略円盤状に形成されて、下面が接地面に接地される。上面には、風量切替ボタンやタイマー等を備える操作パネル２ａが設けられる。ベース部２からは、家庭用コンセントに接続してベース部２の電源２ｂに通電される電源コード（不図示）が設けられる。また、ベース部２内部には、制御回路基板２ｃが設けられる。 Next, an embodiment of the present invention will be described based on the drawings. A fan 1 shown in FIG. 1 includes a base portion 2 . The base portion 2 is formed in a substantially disc shape, and the lower surface thereof is grounded on the ground surface. An operation panel 2a having an air volume switching button, a timer, and the like is provided on the upper surface. A power cord (not shown) is provided from the base portion 2 so as to be connected to a household power outlet and energized to the power source 2b of the base portion 2 . A control circuit board 2 c is provided inside the base portion 2 .

ベース部２からは、上方に向けて支柱３が立設する。支柱３の上端は、モータ２１ａ（図２参照）を備える左右首振り機構２１を介して後述のグリル部３０を支持する支持枠体４と接続される。支持枠体４は、略弓状に形成されて、該弓状の内側にグリル部３０が配置され、中央外側部にて左右首振り機構２１と接続される。モータ２１ａを駆動源とする左右首振り機構２１により、支持枠体４は、支柱３の軸心回りに回転可能に支持される。 A column 3 is erected upward from the base portion 2 . The upper end of the column 3 is connected to a support frame 4 that supports a later-described grill section 30 via a lateral swing mechanism 21 having a motor 21a (see FIG. 2). The support frame 4 is formed in a substantially arcuate shape, and the grill portion 30 is arranged inside the arcuate shape, and is connected to the left/right swinging mechanism 21 at the central outer portion. The support frame 4 is rotatably supported about the axis of the column 3 by a left-right swing mechanism 21 driven by a motor 21a.

また、支持枠体４の両上端４ａ，４ｂのうち、一方の上端４ａはモータ２２ａ（図２参照）を備える上下首振り機構２２が形成される。他方の上端４ｂは、グリル部３０と回転自在に連結する回転軸部２３を備える。グリル部３０は、正面視円形であり、略碗状の前グリル３１及び後グリル部３２が組み合わされて形成される。グリル部３０は、前グリル３１と後グリル部３２の合わせ面３３の上下方向略中央位置にて、上下首振り機構２２及び回転軸部２３により回転可能に支持される。従って、グリル部３０は、支柱３の軸心に直交して上下首振り機構２２と回転軸部２３を通る線を軸心として回転可能とされる。 A vertical swing mechanism 22 having a motor 22a (see FIG. 2) is formed at one upper end 4a of both upper ends 4a and 4b of the support frame 4. As shown in FIG. The other upper end 4b is provided with a rotating shaft portion 23 that is rotatably connected to the grill portion 30. As shown in FIG. The grille portion 30 has a circular shape when viewed from the front, and is formed by combining a substantially bowl-shaped front grille 31 and a rear grille portion 32 . The grill portion 30 is rotatably supported by the vertical swing mechanism 22 and the rotary shaft portion 23 at a substantially central position in the vertical direction of the mating surface 33 of the front grill portion 31 and the rear grill portion 32 . Therefore, the grille portion 30 is rotatable about a line perpendicular to the axis of the column 3 and passing through the vertical swing mechanism 22 and the rotating shaft portion 23 .

グリル部３０は、内部に２枚のファン５ａ，５ｂが同じ軸線上に配置され、互いに反転して回転する。換言すれば、扇風機１は、二重反転式ファンの構成を備える。各ファン５ａ，５ｂは、それぞれモータ４１，４２（図２参照）を備えて各ファン５ａ，５ｂが回転駆動される。扇風機１は、二重反転式ファンであるファン５ａ，５ｂを備えることで、通常の１枚のファンを備える扇風機に比べて噴出風の届く距離が長い。 Two fans 5a and 5b are arranged on the same axis inside the grill section 30, and the fans 5a and 5b rotate in opposite directions to each other. In other words, the fan 1 has a configuration of a counter-rotating fan. The fans 5a and 5b are provided with motors 41 and 42 (see FIG. 2), respectively, to rotate the fans 5a and 5b. The electric fan 1 includes the fans 5a and 5b, which are counter-rotating fans, so that the blowing air reaches a longer distance than a normal electric fan having a single fan.

また、グリル部３０には、前グリル３１の正面視における右側縁部に室温検出部５０が設けられる。室温検出部５０は、扇風機１の風が到達する位置の温度（すなわち、扇風機１からある程度離れた位置の温度）を検出可能に形成される。本実施形態においては、室温検出部５０は、放射温度計等の非接触温度センサにより形成される。 Further, the grille portion 30 is provided with a room temperature detection portion 50 at the right edge portion of the front grille 31 when viewed from the front. The room temperature detection unit 50 is formed so as to be able to detect the temperature at the position reached by the wind from the electric fan 1 (that is, the temperature at a position some distance away from the electric fan 1). In this embodiment, the room temperature detector 50 is formed by a non-contact temperature sensor such as a radiation thermometer.

図２は扇風機１の制御ブロック図である。扇風機１は、制御部１０、記憶部１１、ファン方向変更部２０、ファンモータ駆動部４０を備える。制御部１０は、コンピュータ（ＣＰＵ）により形成される。記憶部１１は、制御部１０と接続する。記憶部１１は、例えば、ＳＳＤ（ＳｏｌｉｄＳｔａｔｅＤｒｉｖｅ）やＳＲＡＭ（ＳｔａｔｉｃＲａｎｄａｍＡｃｃｅｓｓＭｅｍｏｒｙ）で構成され、制御部１０を動作させる制御プログラムや室温値（後述する設定室温差（ＤＴ）、第１設定室温（Ｔ１）～第４設定室温（Ｔ４））等の各種設定値等が記憶される。 FIG. 2 is a control block diagram of the electric fan 1. As shown in FIG. The electric fan 1 includes a control section 10 , a storage section 11 , a fan direction changing section 20 and a fan motor driving section 40 . The control unit 10 is formed by a computer (CPU). Storage unit 11 is connected to control unit 10 . The storage unit 11 is configured by, for example, an SSD (Solid State Drive) or an SRAM (Static Random Access Memory), and stores a control program for operating the control unit 10 and room temperature values (a set room temperature difference (DT) described later, a first set room temperature Various set values such as (T1) to fourth set room temperature (T4) are stored.

制御部１０には、室温検出部５０が接続される。また、制御部１０は、ファン方向変更部２０及びファンモータ駆動部４０と接続し、それぞれを制御する。ファン方向変更部２０は、左右首振り機構２１のモータ２１ａ及び上下首振り機構２２のモータ２２ａと接続して制御する。ファン方向変更部２０は、左右首振り機構２１及び上下首振り機構２２を制御することにより、ファン５ａ，５ｂの向き、すなわち、ファン５ａ，５ｂから噴出される風の向きを、上下方向及び左右方向それぞれ連続して変更可能に形成される。左右首振り機構２１及び上下首振り機構２２は、所定角度範囲で連続してファン５ａ，５ｂの向きを変更可能に形成される。本実施形態では、該所定角度範囲は、左右首振り機構２１及び上下首振り機構２２共に３６０度とされる。 A room temperature detector 50 is connected to the controller 10 . Also, the control unit 10 is connected to the fan direction changing unit 20 and the fan motor driving unit 40 and controls them respectively. The fan direction changing unit 20 is connected to the motor 21a of the horizontal swing mechanism 21 and the motor 22a of the vertical swing mechanism 22 and controls them. The fan direction changing unit 20 controls the horizontal swing mechanism 21 and the vertical swing mechanism 22 to change the directions of the fans 5a and 5b, that is, the directions of the air blown from the fans 5a and 5b in the vertical and horizontal directions. Each direction is formed so as to be continuously changeable. The horizontal swinging mechanism 21 and the vertical swinging mechanism 22 are formed so as to be able to continuously change the directions of the fans 5a and 5b within a predetermined angular range. In this embodiment, the predetermined angular range is 360 degrees for both the horizontal swing mechanism 21 and the vertical swing mechanism 22 .

また、ファンモータ駆動部４０は、モータ４１，４２を制御することで各ファン５ａ，５ｂの回転数を調整し、ファン５ａ，５ｂからの風量を制御することができる。 Further, the fan motor drive section 40 can adjust the rotation speed of each fan 5a, 5b by controlling the motors 41, 42, and can control the air volume from the fans 5a, 5b.

このように形成される扇風機１の使用時の動作の例を図３に基づいて説明する。図３の部屋Ｌは、リビングの一例を示している。部屋Ｌには、天井付近にエアコンＣが設置されている。また、部屋Ｌの一の壁際にはキッチンＫが設置されている。キッチンＫにはコンロＫｏが設置されている。部屋Ｌの略中央には本実施形態に係る扇風機１が置かれている。 An example of the operation of the electric fan 1 formed in this manner during use will be described with reference to FIG. Room L in FIG. 3 shows an example of a living room. In the room L, an air conditioner C is installed near the ceiling. In addition, a kitchen K is installed along one wall of the room L. A stove Ko is installed in the kitchen K. Approximately in the center of the room L, the electric fan 1 according to this embodiment is placed.

（室温サーチ工程）
制御部１０は予め設定した所定の動作プログラムに従って、ファン方向変更部２０（左右首振り機構２１、上下首振り機構２２）によりファン５ａ，５ｂ（グリル部３０）を上下方向及び左右方向に動かし、部屋Ｌ内の複数個所の室温を検出する。例えば、上下首振り機構２２によりファン５ａ（前グリル３１）が真下に向いた状態からファン５ａが真上を向き再び真下を向くまで３０度ずつ上向きに変化させ、上下方向に３０度変化する毎にグリル部３０を左右首振り機構２１により３６０度回転させる。そして、上下方向の３０度毎、水平方向を５度毎に室温検出部５０により室温を検出する。このようにして、制御部１０は、室温検出部５０にファン方向変更部２０（左右首振り機構２１、上下首振り機構２２）の所定角度毎に室温を検出させる。 (Room temperature search process)
The control unit 10 moves the fans 5a and 5b (grill portion 30) vertically and horizontally by means of the fan direction changing unit 20 (horizontal oscillation mechanism 21, vertical oscillation mechanism 22) according to a predetermined operation program set in advance. Room temperatures at multiple locations in room L are detected. For example, the vertical swing mechanism 22 causes the fan 5a (front grille 31) to change upward by 30 degrees from a state in which the fan 5a (front grille 31) is directed directly downward until the fan 5a is directed directly upward and directed downward again. Next, the grill part 30 is rotated 360 degrees by the left and right swinging mechanism 21 . The room temperature detector 50 detects the room temperature every 30 degrees in the vertical direction and every 5 degrees in the horizontal direction. In this manner, the control unit 10 causes the room temperature detection unit 50 to detect the room temperature for each predetermined angle of the fan direction changing unit 20 (horizontal oscillation mechanism 21, vertical oscillation mechanism 22).

該室温サーチ工程は、扇風機１の電源がＯＮされたときに行われてもよいし、操作パネル２ａの操作により該室温サーチ工程を実行してもよい。また、他のモードで運転中に適宜該室温サーチ工程を割り込み処理してもよい。 The room temperature search process may be performed when the electric fan 1 is powered on, or may be performed by operating the operation panel 2a. Further, the room temperature search process may be interrupted as appropriate during operation in another mode.

（室温均一化処理工程）
制御部１０は、室温サーチ工程で検出した室温のうち、最高室温（Ｔｍａｘ）と最低室温（Ｔｍｉｎ）との差が、予め記憶部１１に設定した設定室温差（ＤＴ）よりも高いか否かを比較する（室温比較工程）。そして制御部１０は、最高室温（Ｔｍａｘ）と最低室温（Ｔｍｉｎ）の差が設定室温差（ＤＴ）よりも高い場合（Ｔｍａｘ－Ｔｍｉｎ＞ＤＴ）には、最高室温（Ｔｍａｘ）とされた位置（方向）の室温（Ｔ）が最低室温（Ｔｍｉｎ）に設定室温差（ＤＴ）を加えた室温以下（Ｔ≦Ｔｍｉｎ＋ＤＴ）となるまでファン５ａ，５ｂを最高室温（Ｔｍａｘ）とされた位置（方向）に向くようファン方向変更部２０を制御して、風を送ることができる。このとき、制御部１０は、ファン５ａ，５ｂを駆動するモータ４１，４２に対して、最高室温（Ｔｍａｘ）と最低室温（Ｔｍｉｎ）の差が大きい場合には回転数を上げて風量を増やす等適宜制御することができる。 (Room temperature homogenization process)
The control unit 10 determines whether the difference between the maximum room temperature (Tmax) and the minimum room temperature (Tmin) among the room temperatures detected in the room temperature search step is higher than the preset room temperature difference (DT) set in the storage unit 11 in advance. are compared (room temperature comparison step). When the difference between the maximum room temperature (Tmax) and the minimum room temperature (Tmin) is greater than the set room temperature difference (DT) (Tmax−Tmin>DT), the control unit 10 sets the maximum room temperature (Tmax) to the position ( The position (direction) where the fans 5a and 5b are set to the maximum room temperature (Tmax) until the room temperature (T) in the direction) becomes equal to or lower than the room temperature (T ≤ Tmin + DT) obtained by adding the set room temperature difference (DT) to the minimum room temperature (Tmin) The fan direction changing unit 20 can be controlled to direct the wind. At this time, if the difference between the maximum room temperature (Tmax) and the minimum room temperature (Tmin) is large, the control unit 10 increases the rotation speed of the motors 41 and 42 that drive the fans 5a and 5b to increase the air volume. It can be controlled as appropriate.

例えば、設定室温差（ＤＴ）を１度として設定する。このとき、図３の部屋Ｌの天井付近の位置Ｐ１の室温が２６度で、床付近の位置Ｐ２の室温が２２度である場合には、制御部１０は、ファン５ａ，５ｂ(グリル部３０)を位置Ｐ１に向けて風を送る。扇風機１は、室温検出部５０により検出された位置Ｐ１の室温が２３度以下となる迄位置Ｐ１に風を送り続ける。なお、位置Ｐ１は、ある程度連続した空間である場合には、扇風機１は、ファン方向変更部２０によりファン５ａ，５ｂの向きを変化させながら（すなわち首振りさせながら）、位置Ｐ１に風を送ることもできる。 For example, the set room temperature difference (DT) is set at 1 degree. At this time, when the room temperature at the position P1 near the ceiling of the room L in FIG. ) toward position P1. The electric fan 1 continues blowing air to the position P1 until the room temperature at the position P1 detected by the room temperature detector 50 becomes 23 degrees or less. If the position P1 is a continuous space to some extent, the electric fan 1 sends air to the position P1 while changing the directions of the fans 5a and 5b by the fan direction changing unit 20 (that is, swinging). can also

また、当該室温均一化処理工程における処理時間に閾値を設けて、該閾値以上の処理時間を経過しても最高室温（Ｔｍａｘ）と最低室温（Ｔｍｉｎ）の差が設定室温差（ＤＴ）よりも高い場合（Ｔｍａｘ－Ｔｍｉｎ＞ＤＴ）には、当該室温均一化処理工程を停止したり、エラーメッセージを報知又は通信してユーザーに知らせるようにしてもよい。これにより、エアコンを付けっ放しであったり、部屋Ｌの窓や扉を開けたままにした状態であるために室温ムラが改善されない（すなわち、扇風機１で風を送っても熱が循環しない）状況に対応することができる。 In addition, a threshold is set for the processing time in the room temperature equalization processing step, and even if the processing time equal to or greater than the threshold is passed, the difference between the maximum room temperature (Tmax) and the minimum room temperature (Tmin) is less than the set room temperature difference (DT). If it is higher (Tmax−Tmin>DT), the room temperature equalization process may be stopped, or an error message may be reported or communicated to inform the user. As a result, the room temperature unevenness is not improved because the air conditioner is left on or the windows and doors of the room L are left open (that is, even if the fan 1 blows air, heat does not circulate). I can handle the situation.

（室温均一時処理工程）
また、制御部１０は、室温サーチ工程で検出した室温のうち、最高室温（Ｔｍａｘ）と最低室温（Ｔｍｉｎ）との差が、予め記憶部１１に設定した設定室温差（ＤＴ）以下である場合（Ｔｍａｘ－Ｔｍｉｎ＜ＤＴ）には、室温が略均一であると判断する。この場合、制御部１０は、予め設定された所定の風量にてファンモータ駆動部４０を制御する。 (Room temperature uniform treatment step)
Further, when the difference between the maximum room temperature (Tmax) and the minimum room temperature (Tmin) among the room temperatures detected in the room temperature search step is equal to or less than the set room temperature difference (DT) set in advance in the storage section 11 At (Tmax-Tmin<DT), it is determined that the room temperature is substantially uniform. In this case, the control unit 10 controls the fan motor driving unit 40 at a preset predetermined air volume.

例えば、記憶部１１には、予め第１設定室温（Ｔ１）と、第１設定室温（Ｔ１）よりも高い第２設定室温（Ｔ２）を設定しておく。そして、第１設定室温（Ｔ１）に対応するファン５ａ，５ｂの回転数（すなわち風量）は、第２設定室温（Ｔ２）に対応するファン５ａ，５ｂの回転数（風量）よりも小さく設定しておく。また、第１設定室温（Ｔ１）と第２設定室温（Ｔ２）との間の温度におけるファン５ａ，５ｂの回転数（風量）は、第１設定室温（Ｔ１）に対応するファン５ａ，５ｂの回転数（風量）よりも大きいが第２設定室温（Ｔ２）に対応するファン５ａ，５ｂの回転数（風量）よりも小さく設定することができる。そして、略均一とされる部屋Ｌの室温（Ｔ）は、最高室温（Ｔｍａｘ）又は最低室温（Ｔｍｉｎ）又は両者の平均値とすることができる。 For example, a first set room temperature (T1) and a second set room temperature (T2) higher than the first set room temperature (T1) are set in advance in the storage unit 11 . The rotation speed (ie, air volume) of the fans 5a and 5b corresponding to the first set room temperature (T1) is set lower than the rotation speed (air volume) of the fans 5a and 5b corresponding to the second set room temperature (T2). Keep Further, the number of rotations (air volume) of the fans 5a and 5b at temperatures between the first set room temperature (T1) and the second set room temperature (T2) is It can be set to be higher than the rotation speed (air volume) but lower than the rotation speed (air volume) of the fans 5a and 5b corresponding to the second set room temperature (T2). The substantially uniform room temperature (T) of the room L can be the maximum room temperature (Tmax), the minimum room temperature (Tmin), or the average value of both.

室温均一時処理工程では、例えば、部屋Ｌの室温（Ｔ）が第１設定室温（Ｔ１）以下の室温で略均一である場合（Ｔ≦Ｔ１）には、弱い風量で扇風機１を使用することができる。また、部屋Ｌの室温（Ｔ）が第２設定室温（Ｔ２）以上の室温で略均一である場合（Ｔ≧Ｔ２）には、強い風量で扇風機１を使用することができる。部屋Ｌの室温（Ｔ）が第１設定室温（Ｔ１）と第２設定室温（Ｔ２）との間の室温である場合（Ｔ１＜Ｔ＜Ｔ２）には、中間の風量等とすることができる。 In the uniform room temperature processing step, for example, when the room temperature (T) of the room L is substantially uniform (T≦T1) at or below the first set room temperature (T1), the electric fan 1 is used with a weak airflow. can be done. Further, when the room temperature (T) of the room L is equal to or higher than the second set room temperature (T2) (T≧T2), the electric fan 1 can be used with a strong airflow. When the room temperature (T) of the room L is between the first set room temperature (T1) and the second set room temperature (T2) (T1<T<T2), an intermediate air volume can be set. .

例えば、第１設定室温（Ｔ１）を２１度とし、第２設定室温（Ｔ２）を２８度と設定することができる。または、第１設定室温（Ｔ１）におけるファン５ａ，５ｂの回転数（風量）を最弱に設定し、第２設定室温（Ｔ２）におけるファン５ａ，５ｂの回転数（風量）を最強に設定し、第１設定室温（Ｔ１）と第２設定室温（Ｔ２）間のファン５ａ，５ｂの回転数(風量)は中間の回転数（風量）と設定することもできるし、風量が増減を繰り返すよう設定することもできる。 For example, the first set room temperature (T1) can be set at 21 degrees, and the second set room temperature (T2) can be set at 28 degrees. Alternatively, the rotation speed (air volume) of the fans 5a and 5b at the first set room temperature (T1) is set to the lowest, and the rotation speed (air volume) of the fans 5a and 5b at the second set room temperature (T2) is set to the highest. , the number of rotations (air volume) of the fans 5a and 5b between the first set room temperature (T1) and the second set room temperature (T2) can be set to an intermediate number of rotations (air volume). Can also be set.

なお、該室温均一時処理工程における扇風機１の首振り（ファン方向変更部２０）の動作は、適宜設定することができる。 The operation of swinging the electric fan 1 (fan direction changing unit 20) in the uniform room temperature processing step can be appropriately set.

（高温回避処理工程）
また、記憶部１１には第３設定室温（Ｔ３）が設定され、制御部１０は、前記室温サーチ工程において室温検出部５０が第３設定室温（Ｔ３）以上の室温（Ｔ）を検出した場合（Ｔ≧Ｔ３）にファン５ａ，５ｂ（グリル部３０）の向きが第３設定室温（Ｔ３）以上の温度を検出した位置（方向）を避けるようにファン方向変更部２０を制御する。 (High temperature avoidance treatment process)
A third set room temperature (T3) is set in the storage unit 11, and the control unit 10 detects a room temperature (T) equal to or higher than the third set room temperature (T3) in the room temperature search step. When (T≧T3), the direction of the fans 5a and 5b (grill section 30) is controlled so as to avoid the position (direction) where the third set room temperature (T3) or higher is detected.

例えば、第３設定室温（Ｔ３）を６０度に設定しておけば、第３設定室温（Ｔ３）以上の温度を検出した位置（方向）にキッチンＫのコンロＫｏが存在していると判断することができる。従って、制御部１０は、扇風機１の風がキッチンＫのコンロＫｏを避けるようにファン方向変更部２０を制御することができる。これにより、コンロＫｏの火を扇風機１により消してしまうことを回避することができる。 For example, if the third set room temperature (T3) is set to 60 degrees, it is determined that the stove Ko in the kitchen K is present at the position (direction) where the temperature equal to or higher than the third set room temperature (T3) is detected. be able to. Therefore, the control unit 10 can control the fan direction changing unit 20 so that the wind from the electric fan 1 avoids the stove Ko in the kitchen K. FIG. As a result, it is possible to avoid extinguishing the flame of the stove Ko with the electric fan 1. - 特許庁

（室内循環処理工程）
また、記憶部１１には、第４設定室温（Ｔ４）が設定され、制御部１０は、前記室温サーチ工程において室温検出部５０が第４設定室温（Ｔ４）以下の室温（Ｔ）を検出した場合（Ｔ≦Ｔ４）には、ファン５ａ，５ｂ（グリル部３０）の向きが第４設定室温（Ｔ４）以下の室温を検出した位置（方向）の近傍に向くようにファン方向変更部２０を制御する。 (Indoor circulation treatment process)
Further, a fourth set room temperature (T4) is set in the storage unit 11, and the control unit 10 detects a room temperature (T) equal to or lower than the fourth set room temperature (T4) by the room temperature detection unit 50 in the room temperature search step. (T≦T4), the fan direction changing unit 20 is turned so that the direction of the fans 5a and 5b (grill unit 30) faces the vicinity of the position (direction) where the room temperature below the fourth set room temperature (T4) is detected. Control.

例えば、第４設定室温（Ｔ４）を１０度に設定しておけば、第４設定室温（Ｔ４）以下の室温を検出した位置（方向）にエアコンＣの吹き出し口Ｃ１が存在すると判断することができる。そして、制御部１０は、吹き出し口Ｃ１の近傍、例えば、吹き出し口Ｃ１の直下である位置Ｐ３にファン５ａ，５ｂ(グリル部３０)を向けて風を送ることができる。すると、ファン５ａ，５ｂからの風は吹き出し口Ｃ１の壁に当てられるので、吹き出し口Ｃ１から吹き出される冷たい風を部屋Ｌの天井側に回して部屋Ｌの空気を循環させることができる。これにより、吹き出し口Ｃ１からの冷たい空気が、部屋Ｌの床側に居る人に直接当たってしまうことを回避して、部屋Ｌの室温を均一化することができる。 For example, if the fourth set room temperature (T4) is set to 10 degrees, it can be determined that the outlet C1 of the air conditioner C exists in the position (direction) where the room temperature below the fourth set room temperature (T4) is detected. can. Then, the control unit 10 can direct the fans 5a and 5b (the grill section 30) to the vicinity of the outlet C1, for example, the position P3 directly below the outlet C1 to send the air. Then, the wind from the fans 5a and 5b is applied to the wall of the blowout port C1, so that the cold wind blown out from the blowout port C1 is turned to the ceiling side of the room L to circulate the air in the room L. As a result, cold air from the outlet C1 can be prevented from directly hitting people on the floor side of the room L, and the room temperature of the room L can be made uniform.

なお、前述の高温回避処理工程や上記の室内循環処理工程で直接風を当てないとしたコンロＫｏやエアコンＣの吹き出し口Ｃ１と扇風機１との位置関係は、扇風機１の設置場所を部屋Ｌ内で動かさない限り、変わらない。従って、扇風機１の首振り送風を停止しない限り、送風しない方向（コンロＫｏやエアコンＣの吹き出し口Ｃ１の方向）として記憶した方向には首振りしない（すなわち送風しない）よう扇風機１を設定することもできる。 In addition, the positional relationship between the fan 1 and the blowout port C1 of the stove Ko and the air conditioner C, which are not directly exposed to air in the high temperature avoidance process and the indoor circulation process described above, is determined by placing the fan 1 in the room L. As long as you don't move it with , it won't change. Therefore, the fan 1 is set so as not to swing (i.e., do not blow) in the direction stored as the direction in which no air is blown (the direction of the stove Ko or the outlet C1 of the air conditioner C) unless the fan 1 stops swinging air. can also

（洗濯物乾燥モード）
また、図４に示すように、扇風機１では、洗濯物を効率よく乾燥することができる洗濯物乾燥モードを備える。この洗濯物乾燥モードでは、部屋Ｌに洗濯物Ｗを並べた場合、洗濯物Ｗに対して略均一の風速で扇風機１からの風を当てることができる。 (laundry drying mode)
Further, as shown in FIG. 4, the electric fan 1 has a laundry drying mode in which the laundry can be dried efficiently. In this laundry drying mode, when the laundry W is arranged in the room L, the air from the electric fan 1 can be applied to the laundry W at a substantially uniform wind speed.

この場合、記憶部１１には、室温境界部Ｓを特定するための閾値が設定される。そして、室温サーチ工程の結果、室温Ｔ（第１の室温）と、室温Ｔと所定角度範囲で連続する方向（本実施形態では、扇風機１の正面側左右方向）であって室温Ｔと異なる洗濯物Ｗの温度（室温ＷＴ（第２の室温））が検出されたとする。すると、制御部１０は、室温Ｔと室温ＷＴとの室温差が閾値以上である場合には、室温Ｔと室温ＷＴの隣接位置（方向）を、室温Ｔと室温ＷＴとが隣接する方向に並べられた洗濯物Ｗの端（室温境界部Ｓ）と特定する。 In this case, a threshold value for identifying the room temperature boundary portion S is set in the storage unit 11 . Then, as a result of the room temperature search step, the room temperature T (first room temperature) and the direction that is continuous with the room temperature T within a predetermined angle range (in this embodiment, the left and right directions on the front side of the electric fan 1) and different from the room temperature T. Assume that the temperature of object W (room temperature WT (second room temperature)) is detected. Then, when the room temperature difference between the room temperature T and the room temperature WT is equal to or greater than the threshold, the control unit 10 arranges the adjacent positions (directions) of the room temperature T and the room temperature WT in the direction in which the room temperature T and the room temperature WT are adjacent to each other. The edge (room temperature boundary portion S) of the laundry W that has been washed is specified.

次に、制御部１０は、扇風機１と室温境界部Ｓとのなす角θ（０°＜θ＜９０°）を算出して、室温境界部Ｓにおける風速Ｖを設定する。そして、制御部１０は、ファン５ａ，５ｂの所定首振り角度φ（０°≦φ≦θ）における風速がＶｃｏｓθ／ｃｏｓφとなるようにファンモータ駆動部４０を制御する。これにより、扇風機１から洗濯物Ｗまでの距離が短い中央部分よりも、当該距離が長い端部分（室温境界部Ｓ）におけるファン５ａ，５ｂの回転数を多くする等して高い風速で回転駆動することができるので、洗濯物Ｗに対して均一の風速（風量）で風を当てることができる。従って、洗濯物Ｗをほぼ同じ時間で乾燥させることができる。 Next, the control unit 10 calculates the angle θ (0°<θ<90°) between the electric fan 1 and the room temperature boundary S, and sets the wind speed V at the room temperature boundary S. Then, the control unit 10 controls the fan motor drive unit 40 so that the wind speed at a predetermined swing angle φ (0°≦φ≦θ) of the fans 5a and 5b becomes Vcosθ/cosφ. As a result, the rotation speed of the fans 5a and 5b is increased at the end portion (room temperature boundary portion S) where the distance from the electric fan 1 to the laundry W is short compared to the center portion where the distance is short. Therefore, the laundry W can be blown with a uniform wind speed (air volume). Therefore, the laundry W can be dried in approximately the same time.

なお、室温境界部Ｓにおける風速Ｖは扇風機１の最大風速とすると、洗濯物Ｗを早く乾燥させることができる。ファン５ａ，５ｂの所定首振り角度φ（θ＜φ）における風速は最大風速としてもよいし、送風停止でもよい。０°≦φ≦θの間でのみファン５ａ，５ｂを回転駆動させてもよい。 If the wind speed V at the room temperature boundary portion S is set to the maximum wind speed of the electric fan 1, the laundry W can be dried quickly. The wind speed at a predetermined swing angle φ (θ<φ) of the fans 5a and 5b may be the maximum wind speed, or the blowing may be stopped. The fans 5a and 5b may be rotationally driven only within 0°≦φ≦θ.

このようにして、扇風機１によれば、部屋の状況に応じて適切な風量の風を得ることができる。 In this way, according to the electric fan 1, it is possible to obtain an appropriate amount of air according to the conditions of the room.

以上、本発明の実施形態を説明したが、本発明は本実施形態によって限定されることはなく、種々の変更を加えて実施することができる。例えば、本実施形態では、室温検出部５０をグリル部３０に設けたが、部屋Ｌの各所に室温検出部５０を複数設け、無線通信により部屋Ｌの各所の室温を検出するように構成することもできる。 Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments and can be implemented with various modifications. For example, in the present embodiment, the room temperature detection unit 50 is provided in the grill unit 30, but a plurality of room temperature detection units 50 may be provided at various locations in the room L so as to detect the room temperature at various locations in the room L by wireless communication. can also
