By operating the upward change switch 22, a command signal for moving the center position of the reciprocating range of the fan 1 upward is generated. When a command signal for moving the center position of the reciprocating range of the fan 1 upward is generated, the control device 10 outputs a control signal for controlling the vertical swing motor 7. When a command signal for controlling the vertical swing motor 7 is output, the fan 1 shifts upward. Thereby, the center position of the reciprocating range of the fan 1 in the vertical direction is adjusted.

  The downward change switch 23 of the center position change switch 28 generates a command signal for moving the center position of the reciprocating range of the fan 1 downward. When the downward change switch 23 is operated, a command signal for moving the center position of the reciprocating range of the fan 1 downward is generated. When a command signal for moving the center position of the reciprocating range of the fan 1 downward is generated, the control device 10 outputs a control signal for controlling the vertical swing motor 7. When a command signal for controlling the vertical swing motor 7 is output, the fan 1 shifts downward. Thereby, the center position of the reciprocating range of the fan 1 in the vertical direction is adjusted.

  The amount of movement of the center position of the reciprocating range of the fan 1 in the vertical direction includes the amount of change in the angle of the rotation axis AXf of the fan 1 in the plane orthogonal to the rotation axis AX2. The amount of movement of the center position in the vertical direction depends on the rotation axis AXf of the fan 1 arranged at the center position before the change and the rotation of the fan 1 arranged at the center position after the change in a plane orthogonal to the rotation axis AX2. The angle θ formed by the axis AXf is included.

  When the number of operations of the upward change switch 22 is one, a command signal for moving the center position of the reciprocating range upward by an angle θc is generated. When the number of operations of the upward change switch 22 is 2, a command signal for moving the center position of the reciprocating range upward by an angle 2θc is generated. When the number of operations of the upward change switch 22 is n times, a command signal for moving the center position of the reciprocating range upward by an angle nθc is generated.

  When the number of operations of the downward change switch 23 is one, a command signal for moving the center position of the reciprocating range downward by an angle θd is generated. When the number of times of operation of the downward change switch 23 is 2, a command signal for moving the center position of the reciprocating range downward by an angle 2θd is generated. When the number of operations of the downward change switch 23 is n times, a command signal for moving the center position of the reciprocating range downward by an angle nθd is generated.

  When a command signal for moving the center position of the reciprocating range in the vertical direction is generated, the control device 10 outputs a control signal to the vertical swing motor 7. The vertical swing motor 7 generates power for moving the center position of the reciprocating range in the vertical direction upward or downward. The fan 1 can reciprocate at an angle β in the vertical direction around the center position whose position has been changed by movement.

  When the number of operations of the center position change switch 28 is 1, the angle θ indicating the amount of movement of the center position is an angle θa indicating the amount of movement in the left direction, an angle θb indicating the amount of movement in the right direction, and the upward direction Angle θc indicating the amount of movement and angle θd indicating the amount of downward movement. The angle θa, the angle θb, the angle θc, and the angle θd may be the same value. For example, the angle θa, the angle θb, the angle θc, and the angle θd may be 10 [°]. When the number of operations of the left direction change switch 20 is one, a command signal for moving the center position of the reciprocating range to the left by 10 [°] is generated. When the number of operations of the right direction change switch 21 is one, a command signal for moving the center position of the reciprocating range to the right by 10 [°] is generated. When the number of operations of the upward change switch 22 is one, a command signal for moving the center position of the reciprocating range upward by 10 [°] is generated. When the number of times of operation of the downward direction change switch 23 is 1, a command signal for moving the center position of the reciprocating range downward by 10 [°] is generated. The value of the angle θ is not limited to 10 [°] and can be set arbitrarily.

  The angle θa, the angle θb, the angle θc, and the angle θd may be different values. For example, the angle θa may be 10 [°], the angle θb may be 5 [°], the angle θc may be 15 [°], and the angle θd may be 5 [°]. By one operation of the left direction change switch 20, the center position moves 10 [°] leftward. By one operation of the right direction change switch 21, the center position moves 5 [°] in the right direction. By one operation of the upward change switch 22, the center position moves upward by 15 [°]. By one operation of the downward direction change switch 23, the center position moves downward by 5 [°].

  The restriction unit 31 restricts the acquisition of the command signal by the acquisition unit 30. When the command signal for operating the fan motor 2 by the operation of the on / off switch 25 is acquired by the acquisition unit 30, the acquisition unit 30 outputs the output of the fan motor 2 generated by the operation of the air volume switch 24. A command signal for adjustment is acquired. Even when the air volume switch 24 is operated when the command signal for operating the fan motor 2 is not acquired by the acquisition unit 30, the limiting unit 31 generates the output of the fan motor 2 generated by the operation of the air volume switch 24. The acquisition of the command signal for adjusting is prohibited.

  The state in which the command signal for operating the fan motor 2 by the operation of the on / off switch 25 is acquired by the acquisition unit 30 includes a state in which the on / off switch 25 is “on”. The state where the command signal for operating the fan motor 2 is not acquired by the acquisition unit 30 includes a state where the on / off switch 25 is “OFF”.

  That is, when the on / off switch 25 is “ON”, the acquisition unit 30 receives a command signal for adjusting the output of the fan motor 2 from the air volume switch 24. When the on / off switch 25 is “OFF”, the restricting unit 31 prohibits reception of a command signal for adjusting the output of the fan motor 2.

  When the command signal for operating the fan motor 2 is acquired by the acquisition unit 30 by operating the on / off switch 25, the acquisition unit 30 performs the reciprocating motion generated by the operation of the swing range change switch 29. A command signal for execution and a command signal for adjusting the reciprocating range are acquired. Even when the swing range change switch 29 is operated when the command signal for operating the fan motor 2 is not acquired by the acquisition unit 30, the restriction unit 31 is generated by the operation of the swing range change switch 29. The acquisition of the command signal for executing the reciprocating operation and the command signal for adjusting the reciprocating range is prohibited.

  That is, when the on / off switch 25 is “ON”, the acquisition unit 30 receives a command signal for executing a reciprocating operation from the swing range changing switch 29 and a command signal for adjusting the reciprocating range. When the on / off switch 25 is “OFF”, the restricting unit 31 prohibits reception of a command signal for executing a reciprocating operation and a command signal for adjusting a reciprocating range.

  The acquisition unit 30 is both when the command signal for operating the fan motor 2 is acquired by the acquisition unit 30 and when the command signal for operating the fan motor 2 is not acquired by the acquisition unit 30. The command signal generated by operating the center position change switch 28 can be acquired. When the ON / OFF switch 25 is “ON” and the command signal for operating the fan motor 2 is acquired by the acquisition unit 30 by the operation of the ON / OFF switch 25, the acquisition unit 30 is the center position change switch. The command signal for changing the center position of the reciprocating range generated by the operation of 28 can be acquired. Even when the on / off switch 25 is “OFF” and the command signal for operating the fan motor 2 is not acquired by the acquisition unit 30, the acquisition unit 30 is generated by operating the center position change switch 28. Further, it is possible to acquire a command signal for changing the center position of the reciprocating range.

  The reception period setting unit 32 sets the reception period of the command signal by the acquisition unit 30. The acquisition unit 30 acquires a command signal from the controller device 16 during the reception period set by the reception period setting unit 32. In a period other than the reception period, even when a command signal is generated by the controller device 16, the restriction unit 31 prohibits the acquisition of the command signal by the acquisition unit 30.

  The reception period setting unit 32 sets the start time of the reception period based on the start signal generated by operating the controller device 16. For example, when the center position change switch 28 is operated once in a period in which the reception period is not set, the center position change switch 28 generates a start signal. The start signal generated by operating the center position change switch 28 is supplied to the reception period setting unit 32 via the acquisition unit 30. The reception period setting unit 32 starts the reception period using the supplied start signal as a trigger. The reception period ends when a predetermined time has elapsed from the start time. In other words, the end point of the reception period is a point in time when a predetermined time has elapsed from the start point. The reception period setting unit 32 includes a timer 33 capable of performing time measurement. When the reception period setting unit 32 uses the timer 33 to determine that a predetermined time has elapsed since the start of the reception period, the reception period setting unit 32 ends the reception period.

  Next, the operation of the electric fan 100 according to the first embodiment will be described with reference to FIGS. 5, 6, 7, and 8. In the following description, the operation of the electric fan 100 when the fan 1 performs a reciprocating operation in the left-right direction will be mainly described.

  In the following description, it is assumed that the position of the fan 1 in the reciprocating range is the position of the rotation axis AXf of the fan 1. The reciprocating range setting unit 36 sets an angle α indicating the reciprocating range of the rotation axis AXf. The control unit 37 moves the fan 1 so that the rotation axis AXf is arranged at the center position of the reciprocating range set by the center position setting unit 35. That is, when moving the fan 1 to the center position set by the center position setting unit 35, the control unit 37 moves the fan 1 so that the set center position matches the rotation axis AXf of the fan 1. .

  FIG. 5 shows an example in which the left direction change switch 20 is operated when the horizontal swing switch 26 is operated and the reciprocating operation is performed at the angle α. Before the left change switch 20 is operated, the center position of the reciprocating range is the position B.

  When the left direction change switch 20 is operated during the reciprocating operation of the left and right direction fans 1 and the command signal generated by operating the left direction change switch 20 is acquired by the acquisition unit 30, the control unit 37 The center position of the reciprocating range is moved from position B to position C in the left direction from position B while maintaining the angle α indicating the current reciprocating range.

  In the following description, the center position before being changed by the center position setting unit 35 is appropriately referred to as the center position B or the current center position B, and the center position after being changed by the setting of the center position setting unit 35 Is appropriately referred to as the center position C or the changed center position C. In addition, the round trip range centered on the center position B is appropriately referred to as the current round trip range, and the round trip range centered on the center position C is appropriately referred to as the changed round trip range.

  FIG. 5 shows an example in which the left direction change switch 20 is operated only once. In the example shown in FIG. 5, the angle formed by the rotation axis AXf arranged at the current center position B and the rotation axis AXf arranged at the changed center position C is θ. Note that one operation of the left direction change switch 20 includes an operation of pressing the left direction change switch 20 once, and also includes one long press operation.

  Even after the center position of the reciprocating range is changed from the center position B to the center position C, the angle α indicating the reciprocating range is not changed unless the swing range changing switch 29 is operated. The angle α indicating the current round-trip range and the angle α indicating the changed round-trip range are the same. After the center position of the reciprocating range is changed from the center position B to the center position C, the fan 1 reciprocates in the left-right direction around the center position C at an angle α.

  FIG. 6 shows an example in which the left direction change switch 20 is operated only twice. In the example shown in FIG. 6, the angle formed by the rotation axis AXf arranged at the current center position B and the rotation axis AXf arranged at the changed center position C is 2θ. Note that the two operations of the left direction change switch 20 include an operation of pressing the left direction change switch 20 twice, and also includes two long press operations.

  FIG. 7 shows an example in which the right direction change switch 21 is operated when the horizontal swing switch 26 is operated and the reciprocating operation is executed at the angle α. Before the right direction change switch 21 is operated, the fan 1 reciprocates around the center position B at an angle α.

  When the right direction change switch 21 is operated during the reciprocating operation of the left / right fan 1 and the command signal generated by operating the right direction change switch 21 is acquired by the acquisition unit 30, the control unit 37 The center position of the reciprocation range is moved from the center position B to the center position C in the right direction from the center position B while maintaining the angle α indicating the current reciprocation range.

  FIG. 7 shows an example in which the right direction change switch 21 is operated only once. In the example shown in FIG. 7, the angle formed by the rotation axis AXf arranged at the current center position B and the rotation axis AXf arranged at the changed center position C is θ. Note that one operation of the right direction change switch 21 includes an operation of pressing the right direction change switch 21 once, and also includes one long press operation.

  Even after the center position of the reciprocating range is changed from the center position B to the center position C, the angle α indicating the reciprocating range is not changed unless the swing range changing switch 29 is operated. The angle α indicating the current round-trip range and the angle α indicating the changed round-trip range are the same. After the center position of the reciprocating range is changed from the center position B to the center position C, the fan 1 reciprocates in the left-right direction around the center position C at an angle α.

  FIG. 8 shows an example in which the left direction change switch 20 is operated only six times. In the example shown in FIG. 8, the changed center position C is set outside the current round-trip range. The angle formed by the rotation axis AXf arranged at the current center position B and the rotation axis AXf arranged at the changed center position C is 6θ.

  As shown in FIG. 8, the center position C may be set outside the current reciprocating range, and the fan 1 may be moved from the current center position B to the changed center position C. Even after the center position of the reciprocating range is changed from the center position B to the center position C, the angle α indicating the reciprocating range is not changed unless the swing range changing switch 29 is operated. The angle α indicating the current round-trip range and the angle α indicating the changed round-trip range are the same. After the center position of the reciprocating range is changed from the center position B to the center position C, the fan 1 reciprocates in the left-right direction around the center position C at an angle α.

  The operation of the electric fan 100 when the fan 1 performs the reciprocating operation in the left-right direction has been described above. The operation of the fan 100 when the fan 1 performs a reciprocating operation in the vertical direction is substantially the same as the operation of the fan 100 when the fan 1 performs a reciprocating operation in the left-right direction.

  For example, when the vertical swing switch 27 is operated and the reciprocating operation is being performed at the angle β, when the upward change switch 22 is operated, the control unit 37 maintains the angle β indicating the current reciprocating range. The center position of the reciprocating range is moved from the current center position B to the center position C above the center position B. Even after the center position of the reciprocating range is changed from the center position B to the center position C, the angle β indicating the reciprocating range is not changed unless the swing range changing switch 29 is operated. The angle β indicating the current round-trip range and the angle β indicating the changed round-trip range are the same. After the center position of the reciprocating range is changed from the center position B to the center position C, the fan 1 reciprocates up and down around the center position C at an angle β.

  When the vertical swing switch 27 is operated and a reciprocating operation is being performed at an angle β, when the downward change switch 23 is operated, the control unit 37 maintains the angle β indicating the current reciprocating range. As it is, the center position of the reciprocating range is moved from the current center position B to the center position C below the center position B. Even after the center position of the reciprocating range is changed from the center position B to the center position C, the angle β indicating the reciprocating range is not changed unless the swing range changing switch 29 is operated. The angle β indicating the current round-trip range and the angle β indicating the changed round-trip range are the same. After the center position of the reciprocating range is changed from the center position B to the center position C, the fan 1 reciprocates up and down around the center position C at an angle β.

  Next, the control method of the electric fan 100 according to the first embodiment will be described with reference to the flowchart of FIG. In FIG. 9, the fan motor 2 is operating, and the center position change switch 28 is operated during the reciprocating operation of the fan 1, and a command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30. An example is shown below.

  While the fan 1 is reciprocating, the center position change switch 28 is operated (step SA1). The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30.

  The command signal generated by operating the center position change switch 28 once functions as a start signal for starting the reception period. The start signal is supplied to the reception period setting unit 32 via the acquisition unit 30. The reception period setting unit 32 sets the start time of the reception period based on a start signal generated by operating the center position change switch 28 once. The restriction unit 31 releases the restriction on obtaining the command signal. A command signal reception period is started (step SA2).

  The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30.

  After the acceptance period is started, the controller 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1 (step SA3). The fan 1 stops at the stop position.

  The reception period ends when a predetermined time has elapsed from the start time. When the center position change switch 28 is operated during the reception period, the acquisition unit 30 acquires a command signal generated by operating the center position change switch 28 during the reception period (step SA4).

  The reception period setting unit 32 determines whether or not the reception period has ended based on the time measurement result of the timer 33 (step SA5). If it is determined in step SA5 that the acceptance period has not ended (step SA5: No), acquisition of the command signal by the acquisition unit 30 is continued.

  If it is determined in step SA5 that the acceptance period has ended (step SA5: Yes), the acquisition of the command signal by the acquisition unit 30 ends. After the acceptance period ends, the restriction unit 31 prohibits the acquisition of the command signal by the acquisition unit 30.

  The center position setting unit 35 sets the center position of the reciprocating range of the fan 1 based on the command signal acquired by the acquisition unit 30 during the reception period (step SA6).

  The command signal generated by operating the center position change switch 28 includes a command signal indicating a moving direction and a moving amount for moving the fan 1 from the current center position B to the changed center position C.

  The center position setting unit 35 sets the center position of the reciprocating range of the fan 1 based on the number of operations of the center position change switch 28. The number of operations of the center position change switch 28 includes the number of times the center position change switch 28 is pressed. One operation of the center position change switch 28 is an operation of releasing the pressing after the center position changing switch 28 is pressed. Based on the number of operations of the center position change switch 28, the number of acquisitions by which the acquisition unit 30 acquires the command signal from the center position change switch 28 changes. When the number of operations of the center position change switch 28 is one, the acquisition unit 30 acquires a command signal for one time during the reception period. When the number of operations of the center position change switch 28 is n times, the acquisition unit 30 acquires n times of command signals during the reception period. The center position setting unit 35 sets the center position of the reciprocating range of the fan 1 based on the number of acquisitions of the command signal from the center position change switch 28 acquired by the acquisition unit 30 during the reception period.

  In the reception period, when the left direction change switch 20 among the center position change switches 28 is operated, a command signal for moving the current center position B in the left direction corresponding to the movement direction is generated. When the left direction change switch 20 is operated once during the reception period, a command signal for moving the current center position B by the angle θa corresponding to the movement amount is generated. When the left direction change switch 20 is operated n times during the reception period, a command signal for moving the current center position B to the left by the angle nθa corresponding to the amount of movement is generated. When the left direction change switch 20 is operated n times during the reception period, the acquisition unit 30 acquires the command signal from the left direction change switch 20 n times during the reception period.

  When the right direction change switch 21 of the center position change switches 28 is operated during the reception period, a command signal for moving the current center position B in the right direction corresponding to the movement direction is generated. When the right direction change switch 21 is operated once during the reception period, a command signal for moving the current center position B by the angle θb corresponding to the movement amount is generated. When the right direction change switch 21 is operated n times during the reception period, a command signal for moving the current center position B to the right by the angle nθb corresponding to the movement amount is generated. When the right direction change switch 21 is operated n times during the reception period, the acquisition unit 30 acquires the command signal from the right direction change switch 21 n times during the reception period.

  In the reception period, when the upward change switch 22 among the center position change switches 28 is operated, a command signal for moving the current center position B upward corresponding to the movement direction is generated. When the upward change switch 22 is operated once during the reception period, a command signal for moving the current center position B by the angle θc corresponding to the movement amount is generated. When the upward change switch 22 is operated n times during the reception period, a command signal for moving the current center position B upward by an angle nθc corresponding to the amount of movement is generated. When the upward change switch 22 is operated n times during the reception period, the acquisition unit 30 acquires the command signal from the upward change switch 22 n times during the reception period.

  In the reception period, when the down direction change switch 23 of the center position change switches 28 is operated, a command signal for moving the current center position B downward corresponding to the moving direction is generated. When the downward change switch 23 is operated once during the reception period, a command signal for moving the current center position B by the angle θd corresponding to the movement amount is generated. When the downward change switch 23 is operated n times during the reception period, a command signal for moving the current center position B downward by an angle nθd corresponding to the amount of movement is generated. When the downward change switch 23 is operated n times during the reception period, the acquisition unit 30 acquires the command signal from the downward change switch 23 n times during the reception period.

  The center position setting unit 35 sets the center position based on a command signal from the center position change switch 28 including the movement direction and movement amount of the center position.

  Based on the command signal acquired by the acquisition unit 30 during the reception period, the center position setting unit 35 is changed from the center position B of the current reciprocating range of the fan 1 before the command signal is acquired by the acquisition unit 30. The moving direction and moving amount of the center position up to the center position C of the reciprocating range of the fan 1 are calculated.

  When a plurality of command signals are acquired by the acquisition unit 30 during the reception period, the center position setting unit 35 sets the center position based on the plurality of command signals acquired during the reception period.

  For example, when the acquisition unit 30 acquires the command signal from the left direction change switch 20 h times during the reception period, the center position setting unit 35 determines that the fan is based on the number h of acquisitions of the command signal acquired during the reception period. Set the center position of 1 round-trip range. The movement direction from the current center position B to the changed center position C is the left direction, and the movement amount is hθa.

  When the acquisition unit 30 acquires the command signal from the right direction change switch 21 i times during the reception period, the center position setting unit 35 determines whether the fan 1 has the number of acquisitions i of the command signal acquired during the reception period. Set the center position of the round-trip range. The movement direction from the current center position B to the changed center position C is the right direction, and the movement amount is iθb.

  When the acquisition unit 30 acquires the command signal from the upward change switch 22 j times during the reception period, the center position setting unit 35 determines whether the fan 1 has received the command signal acquisition count j acquired during the reception period. Set the center position of the round-trip range. The moving direction from the current center position B to the changed center position C is upward, and the amount of movement is jθc.

  In the reception period, when the acquisition unit 30 acquires the command signal from the downward direction change switch 23 k times, the center position setting unit 35 determines the fan 1 of the fan 1 based on the acquisition number k of the command signal acquired in the reception period. Set the center position of the round-trip range. The movement direction from the current center position B to the changed center position C is a downward direction, and the movement amount is kθd.

  In the reception period, when the left direction change switch 20 is operated h times, the right direction change switch 21 is operated i times, the up direction change switch 22 is operated j times, and the down direction change switch 23 is operated k times, The acquisition unit 30 acquires the command signal from the left direction change switch 20 h times, acquires the command signal from the right direction change switch 21 i times, and receives the command signal of the upward direction change switch 22 j times during the reception period. The command signal from the downward change switch 23 is acquired k times. The center position setting unit 35 performs calculations based on a plurality of command signals acquired from the left direction change switch 20, the right direction change switch 21, the upper direction change switch 22, and the lower direction change switch 23 during the reception period. Set the center position C. When the angle θa, the angle θb, the angle θc, and the angle θd are the same angle θ, the center position setting unit 35 moves the current center position B by an angle [(h−j) × θ] in the left-right direction. The position moved by the angle [(ki) × θ] in the vertical direction is set as the changed center position C.

  The center position setting unit 35 may set the center position of the reciprocating range of the fan 1 based on the operation time during which the center position change switch 28 is operated. The operation time of the center position change switch 28 includes a pressing time during which the center position change switch 28 is pressed. Based on the operation time of the center position change switch 28, the acquisition time at which the acquisition unit 30 acquires the command signal from the center position change switch 28 changes. If the operation time of the center position change switch 28 is long, the acquisition time of the command signal from the center position change switch 28 acquired by the acquisition unit 30 in the reception period becomes long. When the operation time of the center position change switch 28 is short, the acquisition time of the command signal from the center position change switch 28 acquired by the acquisition unit 30 in the reception period is shortened. The center position setting unit 35 may set the center position of the reciprocating range of the fan 1 based on the acquisition time of the command signal from the center position change switch 28 acquired by the acquisition unit 30 during the reception period.

  For example, when the center position is moved by an angle θ when the center position change switch 28 is operated and the acquisition time of the command signal acquired by the acquisition unit 30 in the reception period is the time Tr, the command signal of the acquisition unit 30 is changed. When the acquisition time is the time Ta, the center position setting unit 35 may set a position shifted from the center position B by an angle [(Ta / Tr) × θ] as the changed center position C.

  After the center position is set by the center position setting unit 35, the control unit 37 outputs a control signal for moving the fan 1 to the set center position C to the swing drive device 15. The control unit 37 outputs a control signal based on the moving direction and moving amount of the center position calculated by the center position setting unit 35.

  The swing drive device 15 that has been stopped in step SA <b> 3 starts to operate based on the control signal output from the control unit 37. As a result, the fan 1 whose reciprocation has been stopped in step SA3 starts to move with respect to the center position C set from the stop position.

  As described above, in the first embodiment, the control unit 37 stops the reciprocating operation of the fan 1 in step SA3 and then outputs a control signal to start the movement of the fan 1 with respect to the set center position C. Let

  The control unit 37 outputs a control signal to control the swing drive device 15. By this control, the fan 1 is moved to the set center position C (step SA7).

  The control unit 37 controls the swing drive device 15 to move the fan 1 to the set center position C, and then stops the swing drive device 15 (step SA8).

  The control unit 37 restarts the reciprocating operation of the fan 1 from the set center position C (step SA9). The control unit 37 outputs a control signal for causing the fan 1 to reciprocate within the reciprocating range set by the reciprocating range setting unit 36 around the center position C set by the center position setting unit 35 to the swing drive device 15. .

  As described above, according to the first embodiment, the control device 10 includes the acquisition unit 30 that acquires the command signal generated when the operation device 16 is operated, and the reciprocation that sets the reciprocation range of the fan 1. Based on the range setting unit 36, the command signal acquired by the acquisition unit 30, the center position setting unit 35 that sets the center position of the reciprocating range, and the fan 1 at the center position C set by the center position setting unit 35. And a control unit 37 that outputs a control signal that moves and reciprocates in a reciprocating range to the swing drive device 15. Based on the command signal generated by operating the center position change switch 28 of the operation device 16, the center position C of the reciprocating range of the fan 1 is set, and is set from the control unit 37 to the swing drive device 15. A control signal for moving the fan 1 to the center position C is output. Therefore, the center position C of the reciprocating range of the fan 1 is set at an arbitrary position at an arbitrary timing. For example, the center position C can be set at an arbitrary timing without waiting for the fan 1 during the reciprocating operation to be arranged at a desired position in the reciprocating range. Further, as described with reference to FIG. 8, the center position C can be set outside the current reciprocating range of the fan 1.

  Further, according to the first embodiment, when the center position change switch 28 is operated, the center position of the reciprocating range is changed while the reciprocating range set by the reciprocating range setting unit 36 is maintained.

  According to the first embodiment, the command signal generated by operating the center position change switch 28 includes the command signal indicating the moving direction and the moving amount for moving the center position. Therefore, the center position can be set to an arbitrary position by adjusting the operating condition of the center position change switch 28.

  Further, according to the first embodiment, the center position setting unit 35 is based on the command signal from the center position change switch 28, and the center position of the reciprocating range of the fan 1 before the command signal is acquired by the acquisition unit 30. The movement direction and movement amount from B to the center position C are calculated, and the control unit 37 outputs a control signal to the swing drive device 15 based on the calculated movement direction and movement amount. Therefore, the user can easily recognize that the reciprocation range has been changed by moving from the current center position B to the changed center position C.

  Moreover, according to Embodiment 1, the control apparatus 10 is provided with the reception period setting part 32 which sets the reception period of a command signal. The center position setting unit 35 sets the center position based on the command signal acquired during the reception period. Thus, since the center position change switch 28 only needs to be operated during the reception period, the user can set the center position with good operability.

  Further, according to the first embodiment, the reception period setting unit 32 sets the start point of the reception period based on the start signal generated by operating the controller device 16. Therefore, the user can start the reception period at an arbitrary timing.

  Further, according to the first embodiment, the center position setting unit 35 sets the center position based on one or both of the number of acquisitions and the acquisition time of the command signal acquired in the reception period. Thereby, the user can operate the operating device 16 with good operability so that the center position is arranged at a desired position. According to the first embodiment, the number of operations or operation time of the center position change switch 28 corresponds to the movement direction and the movement amount. Based on the number of operations or the operation time, the moving direction and moving amount of the center position are determined. Therefore, the user can easily imagine the changed center position C and can set the center position sensuously.

  Moreover, according to Embodiment 1, the center position setting part 35 performs a calculation based on the several command signal acquired in the reception period, and sets a center position. Thus, for example, even if the user mistakenly operates the center position change switch 28, such as when the center position change switch 28 is operated so that the center position moves in a direction different from the desired center position, Further, the center position change switch 28 can be operated so as to correct the operation error. For example, if the left direction change switch 20 is operated by mistake and the right direction change switch 21 is operated by mistake, the error can be corrected by operating the left direction change switch 20 during the reception period. .

  In addition, according to the first embodiment, the center position change switch 28 includes a left direction change switch 20 that is a first operation unit that can generate a command signal for moving the center position in the forward direction of the reciprocating motion in the left-right direction. A right direction change switch 21 which is a second operation unit capable of generating a command signal for moving the center position in the opposite direction of the reciprocating motion in the left-right direction. Further, the center position change switch 28 and the upper direction change switch 22 which is a first operation unit capable of generating a command signal for moving the center position in the forward direction of the up and down reciprocating operation, and the center position up and down reciprocating operation. And a downward change switch 23 which is a second operation unit capable of generating a command signal for moving in the opposite direction. Thereby, good operability can be obtained.

  Further, according to the first embodiment, when the acquisition unit 30 acquires a command signal from the center position change switch 28 during the reciprocating operation of the fan 1, as described in step SA3 in FIG. After the reciprocating operation of the fan 1 is stopped, the movement of the fan 1 with respect to the center position is started. By stopping the reciprocating operation of the fan 1, the user can visually recognize that the reception period has started.

  Further, according to the first embodiment, as described in step SA8 in FIG. 9, the control unit 37 temporarily stops the fan 1 that has moved to the center position C on the spot and starts a reciprocating operation.

  Note that the center position data indicating the set center position C may be stored in the storage unit 34. For example, when resuming the reciprocating operation after stopping the reciprocating operation, the control unit 37 moves the fan 1 to the central position C stored in the storage unit 34 and then reciprocates the fan 1 around the central position C. You may let them. When the storage unit 34 includes a non-volatile memory, the storage unit 34 stores the center position data indicating the center position C, thereby supplying power to the fan 100 after the power supply to the fan 100 is stopped and operating the fan 100. When the control is resumed, the control unit 37 can move the fan 1 to the center position C stored in the storage unit 34.

  If the center position change switch 28 is excessively operated during one acceptance period, it is difficult for the user to imagine the moving direction and moving amount of the center position calculated by the center position setting unit 35. There is a possibility. The excessive operation of the center position change switch 28 includes operating the center position change switch 28 with an excessive number of operations, or operating the center position change switch 28 with an excessive operation time. When the center position change switch 28 is operated excessively, the restriction unit 31 may restrict the number of acquisition times or the acquisition time of the command signal received by the acquisition unit 30 during the reception period. For example, the number of command signal acquisitions may be limited to five times, three times, or twice.

  In the first embodiment, a reception period is set, and calculation is performed in the center position setting unit 35 based on a plurality of command signals acquired during the set reception period, and the movement direction and movement of the center position A quantity is calculated. After the reception period ends and the movement direction and amount of movement of the center position are determined, the reception period setting unit 35 may set a reception period for receiving a command signal from the center position change switch 28. In that case, the center position setting unit 35 adds and subtracts the newly received movement direction and movement amount to the movement direction and movement amount obtained once to determine a new movement direction and movement amount. The control unit 37 may control the swing drive device 15 to move the center position based on the newly determined moving direction and moving amount.

  FIG. 10 is a flowchart illustrating a method for controlling the electric fan 100 according to the first embodiment. FIG. 10 shows that when the fan motor 2 is operating and the reciprocating operation of the fan 1 is stopped, the center position change switch 28 is operated, and the command signal generated by operating the center position change switch 28 is an acquisition unit. 30 shows an example acquired.

  The fan 1 that has stopped reciprocating operation is stopped at the stop position. The operation of the swing drive device 15 is stopped. The storage unit 34 stores center position data indicating the center position B before the change. While the fan 1 stops reciprocating, the center position change switch 28 is operated (step SA1). The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30.

  The reception period setting unit 32 sets the start time of the reception period based on a start signal generated by operating the center position change switch 28 once. After the start time of the reception period is set by the reception period setting unit 32, the restriction unit 31 releases the restriction on the acquisition of the command signal. A command signal reception period is started (step SA2).

  When the center position change switch 28 is operated during the reception period, the acquisition unit 30 acquires a command signal generated by operating the center position change switch 28 during the reception period (step SA4).

  The reception period setting unit 32 determines whether or not the reception period has ended (step SA5). If it is determined in step SA5 that the acceptance period has not ended (step SA5: No), the acquisition of the command signal by the acquisition unit 30 is continued.

  If it is determined in step SA5 that the acceptance period has ended (step SA5: Yes), the acquisition of the command signal by the acquisition unit 30 ends. After the acceptance period ends, the restriction unit 31 prohibits the acquisition of the command signal by the acquisition unit 30.

  The center position setting unit 35 sets the center position C of the reciprocating range of the fan 1 based on the command signal acquired by the acquisition unit 30 during the reception period (step SA6).

The moving direction and moving amount of the center position from the center position B to the center position C of the reciprocating range of the fan 1 after the change are calculated.

  When a plurality of command signals are acquired by the acquisition unit 30 during the reception period, the center position setting unit 35 sets the center position C based on the plurality of command signals acquired during the reception period.

  After the center position C is set by the center position setting unit 35, the control unit 37 outputs a control signal for moving the fan 1 to the set center position C to the swing drive device 15. The control unit 37 outputs a control signal based on the moving direction and moving amount of the center position calculated by the center position setting unit 35.

  The stopped swing drive device 15 starts operating based on the control signal output from the control unit 37. As a result, the fan 1 that has stopped the reciprocating operation starts to move with respect to the set center position C.

  In this way, the control unit 37 moves the fan 1 that is stopped at the stop position and is stopped in the reciprocating operation from the stop position to the set center position C. The head drive device 15 is controlled based on a control signal output from the control unit 37. The fan 1 is moved to the set center position C (step SA7).

The control method described with reference to FIG. 10 may be executed while the fan motor 2 is stopped. The storage unit 34 stores center position data indicating the center position B. When the center position change switch 28 is operated in a state where the on / off switch 25 is operated and the fan motor 2 is stopped, a reception period is set. The acquisition unit 30 receives a command signal from the center position change switch 28 during the set reception period. After the reception period ends, the center position setting unit 35 sets the center position C based on the command signal acquired during the reception period. The center position setting unit 35 calculates a movement direction and a movement amount for moving the fan 1 from the center position B stored in the storage unit 34 to the set center position C. The control unit 37 controls the swing drive device 15 to move the fan 1 to the center position C set by the center position setting unit 35. After the fan 1 is arranged at the set center position C, the control unit 37 stops the swing drive device 15. The set center position C is stored in the storage unit 34.

Obtained command signal. In the second embodiment, after the command signal generated by operating the center position change switch 28 once is acquired by the acquisition unit 30, the limiting unit 31 prohibits acquisition of the command signal. The acceptance period starts when the command signal generated by operating the center position change switch 28 once is acquired by the acquisition unit 30, and ends before the next command signal is acquired. The acquisition part 30 acquires only the command signal produced | generated by one operation.

  The controller 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1. The center position setting unit 35 sets the center position C based on a command signal from the center position change switch 28. The control unit 37 operates the swing drive device 15 to move the fan 1 to the center position C set by the center position setting unit 35. When the fan 1 moves to the set center position C, the control unit 37 stops the swing drive device 15. As a result, the fan 1 is arranged at the set center position C. After the fan 1 stops at the center position C, the control unit 37 controls the swing drive device 15 to restart the reciprocating operation of the fan 1. The reciprocating range of the reciprocating operation of the fan 1 is the same as the reciprocating range set before the center position change switch 28 is operated.

  FIG. 11 is a flowchart illustrating a method for controlling the electric fan 100 according to the second embodiment. When the fan motor 2 is activated and the reciprocating operation of the fan 1 is being executed, the center position change switch 28 is operated once (step SB1). The acquisition unit 30 acquires a command signal generated by operating the center position change switch 28 (step SB2). After the command signal generated by operating the center position change switch 28 once is acquired by the acquisition unit 30, the control unit 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1. (Step SB3). After the command signal generated by operating the center position change switch 28 once is acquired by the acquisition unit 30, the limiting unit 31 prohibits acquisition of the command signal and ends the reception period. When the restriction unit 31 prohibits the acquisition of the command signal, the reception of the command signal ends (step SB4).

  The center position setting unit 35 sets the center position C based on the command signal from the center position change switch 28 (step SB5). The control unit 37 controls the swing drive device 15 to start the movement of the fan 1 with respect to the center position C set by the center position setting unit 35 (step SB6).

  After the movement of the fan 1 is started, the acceptance period is started again (step SB7). When the fan 1 moves to the set center position C, the control unit 37 stops the swing drive device 15. When the swing drive device 15 stops, the movement of the fan 1 ends (step SB8). When the movement of the fan 1 is completed, the fan 1 stops at the set center position C. After the movement of the fan 1 ends, the acceptance period ends (step SB9).

  The acquisition unit 30 receives the command signal from the center position change switch 28 only once during the reception period between step SB7 and step SB9.

  The center position setting unit 35 receives the command signal from the center position change switch 28 during the reception period between step SB7 and step SB9, which is set during the movement period in which the fan 1 moves to the center position C. It is determined whether or not it has been acquired (step SB10).

  When it is determined in step SB10 that a command signal has not been acquired (step SB10: No), the control unit 37 controls the swing drive device 15 to resume the reciprocating operation of the fan 1. The reciprocating range of the reciprocating operation of the fan 1 is the same as the reciprocating range set before step SB1.

  When it is determined in step SB10 that the command signal has been acquired (step SB10: Yes), the center position Cn is reset (step SB11). The center position setting unit 35 resets the center position Cn based on the command signal acquired in the reception period between step SB7 and step SB9. The center position setting unit 35 calculates a moving direction and a moving amount for the fan 1 stopped at the center position C in step SB8 to move to the reset center position Cn.

  As described above, the command signal reception period may be reset during the movement period in which the fan 1 is moved to the center position C set in step SB5. When the command signal is acquired during the reset acceptance period, the control unit 37 is acquired during the reset acceptance period after the fan 1 is arranged and stopped at the center position C that is initially set. The fan 1 may be moved to the center position Cn reset based on the command signal.

  In step SB2, the acquisition unit 30 receives the command signal from the center position change switch 28 only once. In the reception period between step SB7 and step SB9, the acquisition unit 30 receives the command signal from the center position change switch 28 only once. That is, the acquisition unit 30 acquires only one command signal without acquiring a plurality of command signals in one reception period. Thereby, even if the user operates the center position change switch 28 many times, confusion of the user is suppressed.

  Further, the control unit 37 is acquired during the reception period reset at the second timing after the first timing after the fan 1 is moved to the center position C set at the first timing and stopped. Since the fan 1 is moved to the center position Cn reset based on the command signal, the user can visually recognize the reception state of the command signal from the center position change switch 28 by the acquisition unit 30. . Therefore, user confusion is suppressed.

When the fan motor 2 is activated and the reciprocating operation of the fan 1 is being executed, the center position change switch 28 is operated once (step SB1). The acquisition unit 30 acquires a command signal generated by operating the center position change switch 28 (step SB2). The acquisition unit 30 receives a command signal from the center position change switch 28 only once. After the command signal is acquired by the acquisition unit 30, the control unit 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1 (step SB3). The acquisition unit 30 finishes receiving the command signal (step SB4).

  The center position setting unit 35 sets the center position C based on the command signal from the center position change switch 28 (step SB5). The control unit 37 controls the swing drive device 15 to start the movement of the fan 1 with respect to the center position C set by the center position setting unit 35 (step SB6).

  After the movement of the fan 1 is started, the command signal reception period is reset. The reception period is reset to the movement period of the fan 1. The reset acceptance period is started (step SB7).

  In the reception period including the movement period of the fan 1, the center position change switch 28 is operated, and the command signal from the center position change switch 28 is acquired by the acquisition unit 30 (step SB7.2). The acquisition unit 30 receives a command signal from the center position change switch 28 only once.

  The center position setting unit 35 resets the center position Cn based on the command signal acquired in the reset acceptance period (step SB7.4). Further, the acceptance period ends (step SB9).

  The center position setting unit 35 includes a command signal acquired in the first reception period that is the first timing, and a command signal acquired in the reset reception period that is the second timing after the first timing. Based on this, the center position Cn is reset. The center position setting unit 35 resets the center position Cn before the movement period of the fan 1 ends.

  The center position setting unit 35 calculates a movement direction and a movement amount for the fan 1 to move to the reset center position Cn.

  The control unit 37 controls the swing drive device 15 to move the fan 1 to the center position Cn reset in step SB7.4 (step SB12). When the fan 1 moves to the reset center position Cn, the control unit 37 stops the swing drive device 15 (step SB12.2). Thereby, the movement of the fan 1 is completed, and the fan 1 is arranged at the reset center position Cn. The control unit 37 controls the swing drive device 15 to resume the reciprocating operation of the fan 1 (step SB13). The reciprocating range of the reciprocating operation of the fan 1 is the same as the reciprocating range set before step SB1.

  In addition, in the movement period of the fan 1 in step SB12, the reception period of the command signal may be set again.

  In this way, the control unit 37 may move the fan 1 to the reset central position Cn without stopping the fan 1 to the initially set central position C.

  Note that the method for controlling the electric fan 100 described with reference to FIGS. 11 and 12 may be performed when the reciprocating operation of the fan 1 is not executed. Moreover, the control method of the electric fan 100 described with reference to FIGS. 11 and 12 may be performed while the fan motor 2 is stopped. In that case, step SB3 and step SB13 are omitted.

FIG. 13 is a flowchart illustrating a method for controlling the electric fan 100 according to the third embodiment. FIG. 14 is a diagram illustrating the operation of the electric fan 100 according to the third embodiment.

  The storage unit 34 stores the center position B of the current round-trip range. The control unit 37 reciprocates the fan 1 within the current reciprocating range.

  The center position change switch 28 is operated in a state where the center position B of the current reciprocating range is stored in the storage unit 34 (step SC1).

  A command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30 (step SC2). As shown in FIG. 14, when the rotation axis AXf of the fan 1 is disposed at the position A, the center position change switch 28 is operated, and the command signal from the center position change switch 28 is acquired by the acquisition unit 30. To do. The position A is different from the current center position B.

  The control unit 37 moves and stops the fan 1 to the center position B of the reciprocating range of the fan 1 before the command signal from the center position change switch 28 is acquired by the acquisition unit 30. The controller 37 controls the swing drive device 15 to move the fan 1 to the current center position B and stop it (step SC3).

  The center position setting unit 35 sets the center position C based on the command signal acquired by the acquisition unit 30 in step SC2 (step SC4).

  The control unit 37 starts the movement of the fan 1 with respect to the center position C set based on the command signal from the center position change switch 28 acquired by the acquisition unit 30. The control unit 37 controls the swing drive device 15 to move the fan 1 to the changed center position C (step SC5).

  After moving the fan 1 to the center position C, the controller 37 stops the swing drive device 15 (step SC6). As a result, the fan 1 stops at the center position C.

  The control unit 37 controls the swing drive device 15 to resume the reciprocating operation of the fan 1 (step SC7). The reciprocating range of the reciprocating operation of the fan 1 in step SC7 is the same as the reciprocating range of the reciprocating operation of the fan 1 before step SC1.

  In FIG. 14, the changed center position C is set at a position separated by an angle θ to the left of the current center position B, and the position A exists to the left of the center position C. When the command signal from the left direction change switch 20 is acquired by the acquisition unit 30 while the fan 1 is moving from the position A to the current center position B, the control unit 37 moves the fan 1 to the current center position B. Then, after temporarily stopping, it is moved leftward from the current center position B by an angle θ and arranged at the changed center position C, and is temporarily stopped. Thereafter, the control unit 37 reciprocates within the reciprocating range around the center position C.

  Even when the command signal from the left direction change switch 20 is acquired by the acquisition unit 30 while the fan 1 is moving from the center position B to the center position C, the control unit 37 moves the fan 1 to the current center position B. After being moved and temporarily stopped, it is moved leftward from the current center position B by an angle θ and placed at the changed center position C, and is temporarily stopped. Thereafter, the control unit 37 reciprocates within the reciprocating range around the center position C.

  As described above, in the third embodiment, after the control unit 37 moves and stops the fan 1 to the center position B of the reciprocating range of the fan 1 before the command signal is acquired by the acquisition unit 30. The movement of the fan 1 with respect to the center position C set based on the command signal acquired by the acquisition unit 30 is started. Since the fan 1 moves from the current center position B to the set center position C, the user visually recognizes the direction and amount of movement from the center position B before the change to the center position C after the change. be able to. Further, the user can recognize both the current center position B and the changed center position C through vision.

  Note that a command signal reception period from the center position change switch 28 may be set during the movement period of the fan 1 from the center position B to the center position C.

  It should be noted that the position A of the fan 1 when the command signal from the center position change switch 28 is acquired by the acquisition unit 30 may coincide with the current center position B. The control unit 37 temporarily stops the fan 1 at the center position B, and then moves the fan 1 to the center position C. The control unit 37 moves the fan 1 to the center position C, temporarily stops, and then restarts the reciprocating operation of the fan 1.

Embodiment 4 FIG.
FIG. 15 is a flowchart illustrating a method for controlling the electric fan 100 according to the fourth embodiment. FIG. 16 is a diagram illustrating the operation of the electric fan 100 according to the fourth embodiment.

  The fan 1 reciprocates in a reciprocating range around the center position B. The controller 37 reciprocates the fan 1 at the first moving speed (step SD1).

  The center position change switch 28 is operated (step SD2). The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30 (step SD3). The center position setting unit 35 sets the center position C based on the command signal acquired by the acquisition unit 30 (step SD4).

  When the command signal is acquired by the acquisition unit 30, the control unit 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1. As shown in FIG. 16, when the rotation axis AXf of the fan 1 is disposed at the position A, the center position change switch 28 is operated, and the command signal from the center position change switch 28 is acquired by the acquisition unit 30. To do. The fan 1 stops at the position A.

  The control unit 37 controls the swing drive device 15 to move the fan 1 to the changed center position C set by the center position setting unit 35 at the second movement speed (step SD5). The control unit 37 moves the fan 1 stopped at the position A to the center position C at the second movement speed.

  The second moving speed at which the fan 1 is moved from the position A to the center position C set by the center position setting unit 35 is faster than the first moving speed of the fan 1 in the reciprocating operation. For example, the second movement speed is set to twice the first movement speed.

  The control unit 37 stops the swing drive device 15 (step SD6). The fan 1 that has moved to the center position C stops at the center position C as the swing drive device 15 stops. Thereafter, the control unit 37 resumes the reciprocating operation of the fan 1 (step SD7). The fan 1 reciprocates at the first moving speed.

  As described above, according to the fourth embodiment, the second movement speed for moving the fan 1 to the center position C set by the center position setting unit 35 is higher than the first movement speed of the fan 1 in the reciprocating operation. fast. Therefore, the process of changing the center position is performed in a short time. Thereby, the waiting time of the user when changing the center position is shortened.

  The second moving speed for moving the fan 1 to the center position C may be adjusted based on the moving distance for moving the fan 1 to the center position C set by the center position setting unit 35. For example, in FIG. 16, when the angle formed between the rotation axis AXf of the fan 1 arranged at the position A and the rotation axis AXf of the fan 1 arranged at the center position C is equal to or larger than a predetermined threshold value, the control unit 37. The second moving speed for moving the fan 1 to the center position C is made faster than the first moving speed of the fan 1 in the reciprocating operation. When the angle formed between the rotation axis AXf of the fan 1 arranged at the position A and the rotation axis AXf of the fan 1 arranged at the center position C is less than a predetermined threshold value, the control unit 37 moves to the center position C. The second moving speed for moving the fan 1 and the first moving speed of the fan 1 in the reciprocating operation are set to the same speed. That is, when the angle formed between the rotation axis AXf of the fan 1 arranged at the position A and the rotation axis AXf of the fan 1 arranged at the center position C is less than a predetermined threshold, The moving speed for moving the fan 1 to C may not be increased, but may be the same as the moving speed of the fan 1 in the reciprocating operation. The threshold may be 50 [°], for example.

  The moving speed for moving the fan 1 to the center position C may be changed in direct proportion to the moving distance based on the moving distance for moving the fan 1 to the center position C, or may be changed stepwise. Good. When the moving distance for moving the fan 1 to the center position C is the moving distance L1, the moving speed for moving the fan 1 to the center position C is set to the moving speed V1, and the moving distance for moving the fan 1 to the center position C is When the moving distance L2 is longer than the moving distance L1, the moving speed for moving the fan 1 to the center position C is set to a moving speed V2 that is faster than the moving speed V1.

  When the command signal from the center position change switch 28 is acquired by the acquisition unit 30 when the fan 1 is disposed at the position A, the control unit 37 moves the fan 1 from the position A to the center position B. Thereafter, the center position C may be moved. The moving speed when the fan 1 moves from the position A to the center position B and the moving speed when the fan 1 moves from the center position B to the center position C are faster than the moving speed of the fan 1 in the reciprocating operation.

Embodiment 5. FIG.
FIG. 17 is a flowchart illustrating a method for controlling the electric fan 100 according to the fifth embodiment. FIG. 18 is a diagram illustrating the operation of the electric fan 100 according to the fifth embodiment.

  The control unit 37 reciprocates the fan 1 around the center position B. While the fan 1 is reciprocating, the center position changing switch 28 is operated. The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30.

  As shown in FIG. 18, when the rotation axis AXf of the fan 1 is disposed at the first position A1, the center position change switch 28 is operated (step SE1). A command signal from the center position change switch 28 is acquired by the acquisition unit 30 (step SE2).

  When the command signal is acquired by the acquisition unit 30, the control unit 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1 (step SE3). The fan 1 stops at the first position A1.

  The center position setting unit 35 sets the first center position C1 based on the command signal acquired by the acquisition unit 30 (step SE4).

  The control unit 37 controls the swing drive device 15 to move the fan 1 stopped at the first position A1 to the first center position C1 set by the center position setting unit 35 at the third movement speed. (Step SE5).

  The control unit 37 stops the fan 1 moved to the first center position C1 at the first center position C1. Thereafter, the control unit 37 resumes the reciprocating operation of the fan 1 (step SE6). The control unit 37 reciprocates the fan 1 around the first center position C1.

  During the reciprocating operation of the fan 1, when the center axis AXf of the fan 1 is disposed at the second position A2, the center position changing switch 28 is operated (step SE7). The command signal generated by operating the center position change switch 28 is acquired by the acquisition unit 30 (step SE8).

  As shown in FIG. 18, when the rotation axis AXf of the fan 1 is disposed at the second position A2, the center position change switch 28 is operated, and a command signal from the center position change switch 28 is acquired by the acquisition unit 30. I will do it.

  When the command signal is acquired by the acquisition unit 30, the control unit 37 stops the swing drive device 15 and stops the reciprocating operation of the fan 1 (step SE9). The fan 1 stops at the second position A2.

  The center position setting unit 35 sets the second center position C2 based on the command signal acquired by the acquisition unit 30 (step SE10).

  The control unit 37 controls the swing drive device 15 to move the fan 1 stopped at the second position A2 to the second center position C2 set by the center position setting unit 35 at the fourth movement speed. (Step SE11).

  The control unit 37 stops the fan 1 that has moved to the second center position C2 at the second center position C2. Thereafter, the control unit 37 resumes the reciprocating operation of the fan 1 (step SE12). The control unit 37 causes the fan 1 to reciprocate around the second center position C2.

  In FIG. 18, the movement amount of the fan 1 from the first position A1 to the first center position C1 set by the center position setting unit 35 is the first movement amount. The movement amount of the fan 1 from the second position A2 to the second center position C2 set by the center position setting unit 35 is the second movement amount.

  The first movement amount includes the distance between the first position A1 and the first center position C1. The first movement amount includes an angle formed by the rotation axis AXf of the fan 1 arranged at the first position A1 and the rotation axis AXf of the fan 1 arranged at the first center position C1. The second movement amount includes the distance between the second position A2 and the second center position C2. The second movement amount includes an angle formed by the rotation axis AXf of the fan 1 arranged at the second position A2 and the rotation axis AXf of the fan 1 arranged at the second center position C2.

  The first movement amount is smaller than the second movement amount.

  The controller 37 makes the moving speed for moving the fan 1 from the second position A2 to the second center position C2 faster than the moving speed for moving the fan 1 from the first position A1 to the first center position C1.

  That is, when the movement amount of the fan 1 to the second center position C2 set by the center position setting unit 35 is the second movement amount, the fourth movement speed for moving the fan 1 to the second center position C2 is When the movement amount of the fan 1 up to the first center position C1 is the first movement amount smaller than the second movement amount, it is faster than the third movement speed for moving the fan 1 to the first center position C1.

  As described above, according to the fifth embodiment, the moving speed of the fan 1 is set based on the moving amount by which the fan 1 is moved to the center position C set by the center position setting unit 35. When the fan 1 moves through the first movement amount, the control unit 37 moves the fan 1 at the third movement speed. When the fan 1 moves the second movement amount larger than the first movement amount, the control unit 37 moves at a fourth movement speed faster than the third movement speed. Therefore, the process of changing the center position is performed in a short time. Thereby, the waiting time of the user when changing the center position is shortened.

  The moving speed for moving the fan 1 may be changed in direct proportion to the moving amount based on the moving amount of the fan 1 or may be changed stepwise.

Embodiment 6 FIG.
The difference from the first embodiment to the fifth embodiment is that when the center position change switch 28 is operated, the operation of the swing drive device 15 operating for the reciprocating operation of the fan 1 is stopped, and the fan The reciprocating operation 1 is temporarily stopped, the fan 1 is stopped at the stop position, and the center position change switch 28 is operated again between the time when the fan 1 stops at the stop position and the time when a predetermined time elapses. If not, the reciprocating operation of the fan 1 is resumed with the stop position of the fan 1 as the center position, and the center position change switch 28 is set between the time when the fan 1 stops at the stop position and the time when a predetermined time elapses. If operated again, immediately after the operation of the center position change switch 28, the change of the center position is performed based on the command signal generated by operating the center position change switch 28. Because the fan 1 is moved, once it stopped fan 1 to the center position after the change, in terms of resuming a reciprocating motion around the center position after the change. Items that are not described are the same as those in any one of the first to fifth embodiments, and other descriptions are omitted.

  FIG. 19 is a diagram illustrating the operation of the electric fan 100 according to the sixth embodiment. In the reciprocating operation of the fan 1 around the center position B, it is assumed that the left direction change switch 20 is operated when the fan 1 is disposed at the position A. The controller 37 stops the operation of the horizontal swing motor 9 and temporarily stops the fan 1 at the position A. The center position setting unit 35 changes the center position of the reciprocating operation from the center position B to the position A. If the center position change switch 28 is not operated again between the time when the fan 1 stops at the position A and the time when a predetermined time elapses, the position A which is the stop position of the fan 1 is changed. The reciprocating operation of the fan 1 is resumed.

  When the center position change switch 28 is operated again between the time when the fan 1 stops at the position A and the time when a predetermined time elapses, the control unit 37 immediately after operating the center position change switch 28. Then, the fan 1 is moved to the changed center position calculated based on the command signal from the center position change switch 28. For example, when the left direction change switch 20 is operated between the time when the fan 1 stops at the position A and the time when a predetermined time elapses, the control unit 37 performs the operation after the operation of the left direction change switch 20. Immediately, the fan 1 is moved to the changed center position C calculated based on the command signal from the left direction change switch 20. FIG. 19 shows an example in which the left direction change switch 20 is operated once between the time when the fan 1 stops at the position A and the time when a predetermined time elapses. The center position C is a position at an angle θ leftward from the position A.

  The control unit 37 once stops the fan 1 at the center position C, and then restarts the reciprocating operation of the fan 1 around the center position C.

  In the movement period in which the fan 1 moves from the position A to the center position C, a reception period for receiving a command signal from the center position change switch 28 is set. Limiting unit 31 receives the command signal only once during the reception period. The center position setting unit 35 receives a command signal received between the time when the fan 1 stops at the position A and the time when a predetermined time elapses, and a movement period during which the fan 1 moves from the position A to the center position C. Based on the received command signal, a new center position is set again. The center position setting unit 35 determines the position of the fan 1 in the moving direction and moving amount obtained based on the command signal received from the time when the fan 1 stops at the position A to the time when a predetermined time elapses. A new movement direction and movement amount are determined by adding or subtracting the movement direction and movement amount obtained based on the command signal received during the movement period from A to the center position C. The control unit 37 controls the swing drive device 15 to move the center position based on the newly determined moving direction and moving amount.

  In addition, a reception period for receiving a command signal only once is set in the movement period in which the fan 1 moves to the newly set new center position.

  As described above, according to the sixth embodiment, the fan 1 can be moved to a desired center position.

  The center position of the reciprocating operation when the fan 1 is reciprocating in the left-right direction may be changed only by operating the left direction changing switch 20 and the right direction changing switch 21. That is, when the fan 1 is reciprocating in the left-right direction, the center position of the reciprocating operation in the left-right direction is changed, and the center position of the reciprocating operation in the up-down direction need not be changed. When the upward change switch 22 and the downward change switch 23 are operated while the fan 1 is reciprocating in the left-right direction, the control unit 37 moves the head 8 upward or downward, It is not necessary to change the center position of the reciprocating motion in the vertical direction.

  Note that the change of the center position of the reciprocating operation when the fan 1 is reciprocating in the vertical direction may be performed only by operating the up direction change switch 22 and the down direction change switch 23. That is, when the fan 1 is reciprocating in the vertical direction, the center position of the reciprocating motion in the vertical direction is changed, and the center position of the reciprocating motion in the left-right direction need not be changed. When the left direction change switch 20 and the right direction change switch 21 are operated while the fan 1 is reciprocating in the vertical direction, the control unit 37 moves the head 8 leftward or rightward. It is not necessary to change the center position of the reciprocating motion in the left-right direction.

  When the fan 1 is reciprocating in both the left and right directions and the up and down direction, the center position of the reciprocating movement in the left and right direction is changed by operating the left direction changing switch 20 or the right direction changing switch 21. The change of the center position of the reciprocating movement in the direction may be performed by operating the upper direction change switch 22 or the lower direction change switch 23.

  When the reciprocating operation of the fan 1 is stopped, when the left direction change switch 20 or the right direction change switch 21 is operated, the control unit 37 moves the head 8 left or right, The direction of the head 8 can be changed. When the reciprocating operation of the fan 1 is stopped, when the up direction change switch 22 or the down direction change switch 23 is operated, the control unit 37 moves the head 8 in the up direction or the down direction and moves up and down. The direction of the head 8 can be changed.

  The user can understand the operating method of the operating device 16 through vision.

  The configurations shown in the first to sixth embodiments above show an example of the contents of the present invention, and can be combined with other known techniques and do not depart from the gist of the present invention.
