Description

Fan and control method thereof

Technical Field

The present invention relates to a fan and a control method thereof, which can be used in a fan mode and a circulator mode.

Background

In recent years, as shown in fig. 14, the fan can be operated in a circulator mode in which two modes of the up-down oscillation operation and the left-right oscillation operation are combined, in addition to a normal fan mode based on the up-down oscillation operation or the left-right oscillation operation. In the circulator mode, indoor air can be stirred (circulated), and cooling efficiency in summer and heating efficiency in winter can be improved.

For example, patent document 1 discloses a fan capable of swinging a head in an up-down direction and a left-right direction, each of which includes: a left-right shaking control part 46 for controlling the operation of the first stepping motor 26, and a up-down shaking control part 46 for controlling the operation of the second stepping motor 27.

Disclosure of Invention

Problems to be solved by the invention

However, during use in the circulator mode, when the on/off button is pressed to stop the fan, the fan stops in the direction of the blades when the on/off button is pressed. Therefore, the orientation of the blades becomes relatively random each time. Although there is no problem when the fan is used in the circulator mode next time, the oscillating up and down operation must be performed for a while and the oscillating up and down operation must be stopped after the blades are directed in the predetermined up and down direction before the oscillating up and down operation is started when the fan is used in the normal fan mode next time (for example, the oscillating left and right operation). Such an operation is time-consuming and laborious and is poor in usability. Further, when the blade is manually moved to direct the blade in a desired direction, an excessive force may be applied to the gear of the oscillating motor, and the gear may be damaged.

Therefore, in order to solve this problem, the present applicant has proposed a fan that can be used in a fan mode and a circulator mode, using a mechanical switch or an optical switch, and adjusting blades to a state of being directed to a predetermined direction among the up-down direction and/or the left-right direction (japanese patent laid-open No. 2014-161038). The applicant has further improved the fan in the present invention, and proposed a fan and a control method thereof which omit a switching mechanism and an electronic circuit for detecting a position, thereby simplifying a structure and reducing costs.

Detailed Description

Hereinafter, embodiments of the fan according to the present invention will be described in detail with reference to the drawings.

Fig. 1 is a front view of the fan of the present invention. The Z axis represents the up-down direction, and the Y axis represents the left-right direction.

The fan 100 has: a blade 1 (a rail is shown by a two-dot chain line), a motor 2 for the blade for rotating the blade 1, a vertical oscillation mechanism for oscillating the blade 1 in the vertical (vertical) direction, a horizontal oscillation mechanism for oscillating the blade 1 in the horizontal (horizontal) direction, a slide pipe 30 which slides up and down for adjusting the height of the blade 1, a support column 31 connected to the slide pipe 30, a base 40 connected to the support column 31, and an operation panel 50 which is provided on the base 40 and controls the operation of the fan 100. The blade 1 is provided at a rotation shaft tip 3 of the blade motor 2.

In fig. 1, the blade 1 faces the front in the vertical direction and the front in the horizontal direction, i.e., the X direction.

The fan 100 includes, as an up-down oscillating mechanism: a tilt-up motor 12, a drive gear 13 and a driven gear 14 of the tilt-up motor 12, a support shaft 15, and a motor housing 16 that rotates about the support shaft 15 and to which the blade motor 2 is attached. When the tilt motor 12 rotates, a drive gear 13 attached to the tilt motor 12 and a driven gear 14 (rotatably supported by a support shaft 15) interlocked with the drive gear 13 rotate, and a motor housing 16 attached to the driven gear 14 rotates.

The oscillating motor 12 is, for example, a stepping motor having a conventionally known automatic reverse mechanism, and automatically reverses after rotating a certain angle to oscillate the blade 1 up and down. The control of the oscillating up and down motor 12 will be described later.

In the illustrated example, the support shaft 15 is fixed to the support body 26 and the support shaft 15 does not rotate, but the support shaft 15 may be fixed to the motor housing 16 and the support shaft 15 may rotate together with the motor housing 16. In the illustrated example, the rotation of the vertical oscillation motor 12 is transmitted to the motor housing 16 by the drive gear 13 and the driven gear 14, but the vertical oscillation motor 12 may be directly attached to the motor housing 16, and the drive gear 13 and the driven gear 14 may be omitted.

As shown in fig. 2, the fan 100 is operated by about 10 ° with respect to the X direction by rocking downward and about 90 ° with respect to the X direction by rocking upward. The angle of the oscillating motion in the up-down direction is not limited to this angle.

Referring again to fig. 1, the left-right oscillating mechanism of the fan 100 will be described.

The fan 100 includes, as a yaw mechanism: the pan motor 22, the drive gear 23 and the driven gear 24 of the pan motor 22, the rotation shaft 25, and the support 26 attached to the rotation shaft 25 to rotate around the rotation shaft 25, and when the pan motor 22 rotates, the drive gear 23 attached to the pan motor 22 and the driven gear 24 (which is fixed to the rotation shaft 25) interlocked with the drive gear 23 rotate, and the support 26 attached to the rotation shaft 25 rotates. The support body 26 and the rotary shaft 25 are rotatably supported by the slide pipe 30.

The yaw motor 22 is, for example, a stepping motor, and has a conventionally known automatic reverse mechanism (not shown) that automatically reverses after rotating a certain angle, thereby enabling the blade 1 to yaw left and right. The control of the yaw motor 22 will be described later.

In the illustrated example, the rotary shaft 25 is fixed to the support 26, and the rotary shaft 25 and the support 26 rotate together, or the rotary shaft 25 may be fixed to the slide pipe 30, and only the support member 26 rotates without rotating the rotary shaft 25. The rotation of the yaw motor 22 is transmitted to the support 26 by using the drive gear 23 and the driven gear 24, and the yaw motor 22 may be directly attached to the support 26, and the drive gear 23 and the driven gear 24 may be omitted.

As shown in fig. 3(a), the fan 100 can perform a swing operation of about 70 ° left and right. The angle of the yaw motion in the left-right direction is not limited to this angle.

Fig. 3(b) schematically shows the side-to-side oscillating operation of the fan 100. Between the oscillation limit position (left) and the oscillation limit position (right), the oscillation range of the blade 1 is defined. Let the respective operation times from the center to the panning limit position (left) and the panning limit position (right) be the reference time t 0.

It is assumed that the blade 1 is initially in a state of being directed to the front in the left-right direction.

At a time p0, fan 100 starts the yaw operation, and blade 1 performs the yaw operation in the left-right direction. Then, the operation time from the time p0 is measured.

At the time p1, since the predetermined reference time t0 has elapsed from the time p0, the pan motor 22 reaches the pan limit position (right), and therefore the pan motor 22 rotates in reverse. Then, the blade 1 performs a swing motion leftward.

At the time p2, a predetermined time 2t0 elapses from the time p0 (a predetermined time t0 elapses from the time p 0), the blade 1 passes through the front position (center) in the left-right direction, and then, the panning operation is performed to the left. Here, the operation time from the time p0 is reset (cleared), and the operation time from the time p2 is measured.

At the time p3, since the predetermined reference time t0 has elapsed from the time p2, the pan motor 22 reaches the pan limit position (left), and therefore the pan motor 22 rotates in reverse. Then, the blade 1 performs a swing motion in a right direction.

At the time p4, a predetermined time 2t0 elapses from the time p2 (a predetermined time t0 elapses from the time p 3), the blade 1 passes the front position (center) in the left-right direction, and then, the panning operation is performed in the right direction. Here, the operation time from the time p2 is reset (cleared), and the operation time from the time p4 is measured.

The operation from the time p0 to the time p4 is repeated.

Finally, at time pn, the fan 100 stops the yaw operation in the left-right direction with the blade 1 facing the front in the left-right direction.

In fig. 3(c), the blade 1 is assumed to be in a state facing the right of the center.

At a time p0, fan 100 starts the yaw operation, and blade 1 swings to the right. Since the yaw motor 22 has reached the yaw restricting position (right) before the predetermined reference time t0 has elapsed from the time p0, the yaw motor 22 is locked (restricted) from idling (blocked) at this position. Thereafter, at a time p1 when a predetermined reference time t0 elapses from the time p0, the yaw motor 22 rotates in reverse, and the blade 1 performs a yaw operation in the left direction. At a timing p2 when a predetermined reference time t0 has elapsed from the timing p1, the blade 1 is located at a position that coincides with the front face in the left-right direction.

Therefore, when the blade 1 is not facing the front in the left-right direction at the time of product shipment, or when the user starts the left-right oscillating operation of the fan 100 in a state where the angle of the blade 1 is moved, the center of the left-right oscillating movable range coincides with the center of the left-right oscillating time (2t0) between the oscillation restricting positions.

In fig. 3(d), the blade 1 is assumed to be in a state facing the left of the center.

At a time p0, fan 100 starts the yaw operation, and blade 1 swings to the right. Even if the predetermined reference time t0 elapses from the time p0, the leftward and rightward rocking motor 22 has not yet reached the rocking restricted position (rightward). Then, at time p1, the yaw motor 22 rotates in reverse, and the blade 1 performs a yaw operation leftward. At time p2, the blade 1 is in a state facing to the left of the center. Before the predetermined reference time t0 elapses from the time p2, the yaw motor 22 reaches the yaw restricting position (left), and therefore, the yaw motor 22 is locked (restricted) from idling (blocked) at this position. Thereafter, at a timing p4 when a predetermined reference time t0 has elapsed from the timing p3, the blade 1 is located at a position that coincides with the front face in the left-right direction.

Fig. 4 illustrates an example of blocking in fig. 3(c) and (d).

When the driven gear 24 is rotated in the direction of the arrow b from the state (a) of fig. 4, as shown in fig. 4(b), the surface 24b of the driven gear 24 contacts the rotation limit stopper 27. On the other hand, when the driven gear 24 is rotated in the direction of the arrow c from the state of fig. 4(a), as shown in fig. 4(c), the surface 24c of the driven gear 24 contacts the rotation limit stopper 27.

In this way, the yaw motor 22 is restricted in its yaw movement range to an angle corresponding to the predetermined reference time t0 in the left and right direction of the yaw motor 22 by the rotation limit stopper 27 configured to the driven gear 24 (it is desirable to slightly widen the yaw movement range from t 0).

A left-right shaking operation stop routine of the fan 100 will be described with reference to fig. 5.

Case 1

The blade 1 performs a yaw operation in a direction away from the center through the center (front position in the left-right direction). At time p when the operation time of time t1 elapses from the center, a button (described later) for stopping the yaw operation is pressed, and the yaw motor 22 is immediately reversed. Then, in the panning operation of the blade 1 to the right at time t1 in the direction approaching the center, the pan motor 22 is stopped with the blade 1 facing the front in the left-right direction.

Case 2

The blade 1 performs a yaw operation leftward and rightward in a direction toward the center. At time p when the operation time of time t1 elapses from the center, the button for stopping the yaw operation is pressed, the blade 1 continues the yaw operation toward the left in the direction approaching the center for time (2t0-t1), and the yaw motor 22 is stopped with the blade 1 facing the front in the left-right direction.

Case 2'

Case 2' is the same as case 2, and the blade 1 performs a yaw operation to the left in a direction toward the center. In addition to the operating time t1 from the center, an operating time t2 from the (right) reversal of the oscillation limit position is also read. At time p when the operation time of time t2 elapses from the reverse rotation position, the button for stopping the yaw operation is pressed, the blade 1 continues the yaw operation toward the left side in the direction approaching the center for a time (t0-t2), and the yaw motor 22 is stopped with the blade 1 facing the front side in the left-right direction.

Fig. 6(a) is a flowchart showing a side-to-side shaking operation stop routine of the fan 100 with respect to case 1 and case 2.

When a button for stopping the operation of shaking the head left and right is pressed, a left and right shaking operation stop routine is entered.

In step S2, the operating time t1 from the center is read in. In step S3, in the case where t1< t0 (yes), in step S4, the panning direction of the blade 1 is reversed. In step S5, the panning operation is performed at time t1, and in step S9, the panning motor 22 is stopped. Steps S2 to S5, S9 show the flow of case 1 described above.

In step S3, if no, the panning operation is continued for a time (2t0-t1) in step S6, and the panning motor 22 is stopped in step S9. Steps S2 to S3, S6, S9 show the flow of case 2 described above.

Fig. 6(b) is a flowchart showing the left-right shaking head operation stop routine of the fan 100 with respect to case 1 and case 2'.

The flow of case 1 is the same as that in fig. 6(a) and is omitted.

In step S3, if no, in step S7, the operation time from the inversion position is read (t 2). In step S8, the panning operation is continued for a time (t0-t2), and in step S9, the pan motor 22 is stopped. Steps S2 to S3, S7 to S9 show the flow of the above case 2'.

Next, the oscillating operation of the fan 100 in the up-down direction will be described.

Referring again to fig. 2, the oscillation limiting position (up) and the oscillation limiting position (down) are the range of the upward and downward oscillating movement of the blade 1. Since the blade 1 is inclined upward at the center of the oscillating up and down range of motion, it is more comfortable for the user to stop the blade 1 in a state of facing the horizontal position than to stop the blade 1 in this state. Therefore, in the case of the up-and-down swing operation, the blade 1 is controlled to be stopped not in a state of being directed toward the center but in a state of being directed toward the horizontal position. The operation times from the center to the oscillation restricting position (up) and the oscillation restricting position (down) are set as reference times (t0), and the operation time from the center to the horizontal position is set as a stop time (t 3).

The oscillating up and down operation stop routine of the fan 100 will be described with reference to fig. 7.

Cases 1 to 3 correspond to an operation in a case where a button (described later) for stopping the up-down swing operation is pressed when the swing operation is performed upward (direction 1 in the claims), and cases 4 to 6 correspond to an operation in a case where a button for stopping the up-down swing operation is pressed when the swing operation is performed downward (direction 2 in the claims).

Case 1

The blade 1 swings upward in a direction away from the center position through the center position. When the button for stopping the up-down shaking operation is pressed at time p when the operation time of time t1 has elapsed from the center position, the up-down shaking motor 12 is immediately rotated in reverse. Thereafter, when the blade 1 passes through the center position and reaches the horizontal position, the up-down rocking motor 12 is stopped. That is, after the head-down operation is performed at time (t1+ t3) from the time of the reverse rotation, the head-up-down motor 12 is stopped.

Case 2

After the blade 1 is reversed at the oscillation restricting position (down), the oscillating operation is performed upward in a direction approaching the horizontal position. When the button for stopping the upward and downward swing motion is pressed at time p when the operation time of time t2 has elapsed from the reverse position, the blade 1 continues to swing upward in a direction approaching the horizontal position. When the blade 1 reaches the horizontal position, the up-down oscillating motor 12 is stopped. That is, the up-and-down swing motor 12 is stopped after the up-and-down swing operation is performed for a time ((t0-t2) -t3) from the time when the button for stopping the up-and-down swing operation is pressed.

Case 3

After the blade 1 is reversed at the oscillation limiting position (lower position), the blade oscillates upwards in the direction away from the horizontal position. When the button for stopping the up-down shaking operation is pressed at time p when the operation time of time t2 has elapsed from the reverse rotation position, the up-down shaking motor 12 is immediately rotated in reverse. Thereafter, when the blade 1 reaches the horizontal position, the up-down rocking motor 12 is stopped. That is, after the head-down operation is performed at time (t3- (t0-t2)) from the time of reverse rotation, the head-up-down motor 12 is stopped.

Case 4

The blade 1 swings downward in a direction approaching a horizontal position through the center position. When the button for stopping the upward and downward swing motion is pressed at time p when the operation time of time t1 has elapsed from the center position, the blade 1 continues to swing downward in a direction approaching the horizontal position. When the blade 1 reaches the horizontal position, the up-down oscillating motor 12 is stopped. That is, the panning up and down motor 12 is stopped after the panning down operation is performed for a time (t3-t1) from the time when the button for stopping the panning up and down operation is pressed.

Case 5

The blade 1 swings downwards in the direction away from the horizontal position. When the button for stopping the up-down shaking operation is pressed at time p when the operation time of time t1 has elapsed from the center position, the up-down shaking motor 12 is immediately rotated in reverse. Thereafter, when the blade 1 reaches the horizontal position, the up-down rocking motor 12 is stopped. That is, after the head up-swing operation is performed for a time (t1-t3) from the time of the reverse rotation, the head up-down swing motor 12 is stopped.

Case 6

After the blade 1 is reversed at the oscillation limit position (upper position), the oscillating operation is performed downward in a direction approaching the center position. When the button for stopping the upward and downward swing motion is pressed at time p when the operation time of time t2 has elapsed from the reverse position, the blade 1 continues to pass through the center position, and the swing motion is performed downward in a direction approaching the horizontal position. When the blade 1 reaches the horizontal position, the up-down oscillating motor 12 is stopped. That is, the up-down swing motor 12 is stopped after the down-swing operation is performed for a time ((t0-t2) + t3) from the time when the button for stopping the up-down swing operation is pressed.

In cases 2, 3, and 6 of fig. 7, the time t2 is used from the reverse rotation position, but the operation time of the panning motors 12 can be controlled so that the time t2 is not used (t2 is t1-t 0).

Instead of the vertical swing motor 12, the horizontal swing motor 22 may be controlled to stop at a position shifted from the center position.

Fig. 8 is a flowchart showing an oscillating up and down operation stop routine of the fan 100.

When a button for stopping the up-down shaking operation is pressed, the up-down shaking operation stop routine is entered.

In step S2, the operation time from the center is read in (t 1). If it is determined in step S3 that the oscillating direction of the blade 1 is upward, step S4 is executed. In step S4, in the case where t1< t0 (yes), in step S5, the panning direction of the blade 1 is reversed. In step S6, the panning down operation is performed at time (t1+ t3), and in step S20, the panning up and down motor 12 is stopped. Steps S2 to S6, S20 show the flow of case 1 described above.

If the determination result in step S4 is no, the operation time from the reverse rotation position is read in step S7 (t 2). When the oscillating direction of the blade 1 is the direction approaching the horizontal position (yes) in step S8, the upward oscillating operation is continued for a time ((t0-t2) -t3) in step S9, and the upward and downward oscillating motor 12 is stopped in step S20. Steps S2 to S4, S7 to S9, S20 show the flow of case 2 described above.

When the oscillating direction of the blade 1 is a direction away from the horizontal position in step S8 (no), the oscillating direction of the blade 1 is reversed in step S10. In step S11, the panning operation is performed downward at time (t3- (t0-t2), and in step S20, the panning motor 12 is stopped, and steps S2 to S4, S7 to S8, S10 to S11, and S20 show the flow of case 3.

In step S3, if the result of the determination is no and the direction of the blade 1 shaking the head is downward, step S13 is performed. In step S13, in the case where t1< t0 (yes), step S14 is performed. When the oscillating direction of the blade 1 is the direction approaching the horizontal position in step S14 (yes), the downward oscillating operation is continued for a time (t3-t1) in step S15, and the up-down oscillating motor 12 is stopped in step S20. Steps S2 to S3, S13 to S15, S20 show the flow of case 4 described above.

When the oscillating direction of the blade 1 is a direction away from the horizontal position in step S14 (no), the oscillating direction of the blade 1 is reversed in step S16. In step S17, the upward panning operation is continued for a time (t1-t3), and in step S20, the upward and downward panning motor 12 is stopped. Steps S2 to S3, S13 to S14, S16 to S17, and S20 show the flow of case 5 described above.

If the determination result is no in step S13, the operation time from the inversion position is read in step S18 (t 2). In step S19, the panning down operation is continued for a time ((t0-t2) + t3), and in step S20, the panning up and down motor 12 is stopped. Steps S2 to S3, S13, S18 to S20 show the flow of case 6 described above.

Fig. 9 shows an example of the operation panel 50 of the fan 100 according to the present invention. In the illustrated example, the operation panel 50 provided on the base 40 will be described, and the operation panel may be provided in a remote controller.

The operation panel 50 is divided into a fan function section, a circulator function section, and a common function section.

As an operation button for the fan mode, the fan function section is provided with: an on/off button (a1) for an on/off fan mode, an up-and-down oscillating button (B1) for oscillating the blade 1 in the up-and-down direction, a left-and-right oscillating button (C1) for oscillating the blade 1 in the left-and-right direction, and a rhythm wind button (E1) for randomly changing the wind volume. In the fan mode, one of the yaw motor 12 and the yaw motor 22 operates, and the fan 100 operates as a normal fan.

As an operation button for the circulator mode, the circulator function section is provided with: an on/off button (a2) for turning on/off the circulator mode, an up-down shaking button (B2) for shaking the blade 1 in the up-down direction, a left-right shaking button (C2) for shaking the blade 1 in the left-right direction, and a stirring button (D2) for shaking the blade 1 in the up-down direction and the left-right direction simultaneously. In the circulator mode, mainly for stirring the indoor air, both the up-down swing motor 12 and the left-right swing motor 22 operate, and the fan 100 operates as a circulator.

As an operation button for a function common to the fan mode and the circulator mode, the common function section is provided with: a timer on button (F) and a timer off button (G) for adjusting the timer, and an air volume button (H) for adjusting the air volume in stages.

Therefore, by separately providing the operation buttons for the fan mode and the circulator mode, respectively, and providing the operation buttons for the fan mode and the circulator mode in common, it is possible to provide the easy-to-use operation panel 50 which is easy to understand by the user.

Fig. 10 is a flowchart of the fan mode (the up-down shaking operation routine and the left-right shaking operation routine).

When the fan mode on/off button (a1) is pressed in step S1 and the signal of "on (on)" is recognized, the blade motor 2 is turned on in step S2. When recognizing that the panning up and down button (B1) is pressed in step S3, the panning up and down motor 12 is turned on in step S4, and the panning up and down operation routine is entered. When it is recognized in step S5 that the pan button (C1) is pressed, the pan motor 22 is turned on in step S6, and the pan operation routine is entered.

Fig. 11 is a flow chart of the circulator mode.

When the circulator mode on/off button (a2) is pressed and the signal of "on" (on) is recognized in step S1, the blade motor 2, the pan motor 12, and the pan motor 22 are all turned on in step S2. The fan 100 operates as a circulator.

When the up-down shaking button (B2) is pressed in step S3, the pan motor 22 is turned off in step S4, and the up-down shaking operation routine is entered.

When the panning button (C2) is pressed in step S5, the panning motor 12 is turned off in step S6, and the panning operation routine is entered.

In step S7, when the on-timer button (F) or the off-timer button (G) is pressed, a timer operation routine is entered.

In step S8, when the air volume button (H) is pressed, the routine proceeds to the air volume adjusting routine.

When the circulator mode on/off button (a2) is pressed and the "off" signal is recognized in step S9, the blade motor 2 is turned off in step S10, and the up-down panning operation stop routine and the left-right panning operation stop routine are then performed to stop the fan 100.

Further, step S7 and step S8 function similarly even in the up-down panning operation routine and the left-right panning operation routine.

Fig. 12 shows another example of the operation panel 50 of the fan 100 according to the present invention. In the illustrated example, an on/off button (i) for turning on/off the power of the fan 100 is provided in addition to the buttons of fig. 9.

Fig. 13 shows a block diagram of a control circuit of the fan 100 of the present invention.

The controller includes a control unit for the blade motor 2, a control unit for the vertical oscillation motor 12, a control unit for the horizontal oscillation motor 22, and a storage unit. The controller is connected with a display/operation part and a power supply part. Buttons (a1 to i) of the operation panel 50 are arranged in the display/operation section.
