Description

[Technical Field]

[0001] The present disclosure relates to a blowing technique, and more particularly to a blowing device that performs an oscillating reciprocating motion. [Background technology]

[0002] In an electric fan that can oscillate back and forth, it is required to set the center position of the fan's reciprocating range at any position at any timing. To this end, the fan's reciprocating range is set, and the center position of the reciprocating range is set by performing a calculation based on a command signal generated by operating an operating device within a reception period (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-017240 Summary of the Invention [Problem to be solved by the invention]

[0004] When setting the angle of the reciprocating oscillation, the user sets it while actually causing the fan to oscillate back and forth, and in this case, it is required to be able to set the angle of the reciprocating oscillation easily and freely.

[0005] The present disclosure has been made in view of these circumstances, and its purpose is to provide a technique for easily and freely setting the angle of the reciprocating oscillating motion. [Means for solving the problem]

[0006] In order to solve the above problem, one embodiment of the blower device of the present invention comprises an oscillating drive unit that can cause the fan to oscillate back and forth between a first limit end and a second limit end, a control unit that sets a first stop end and a second stop end between the first limit end and the second limit end and instructs the oscillating drive unit to oscillate back and forth between the first stop end and the second stop end, and an operation unit that accepts operations to change the first stop end and the second stop end. The first stop end is closer to the first limit end than the second stop end, and the second stop end is closer to the second limit end than the first stop end. When the operating unit receives a first operation while the fan is rotating from the first stop end toward the second stop end, the control unit instructs the swing drive unit to change the range of the fan's reciprocating swing motion from between the first stop end and the second stop end to between the first limit end and the second limit end. When the operating unit receives a first operation, the control unit stores the angle of the fan when the first operation is received as the third stop end. When the operating unit receives a second operation while the fan is rotating toward the second limit end after receiving the first operation, the control unit stores the angle of the fan when the second operation is received as the fourth stop end. The control unit instructs the swing drive unit to change the range of the fan's reciprocating swing motion from between the first limit end and the second limit end to between the third stop end and the fourth stop end.

[0007] Another aspect of the present invention is a blower including an oscillation drive unit that can oscillate a fan back and forth between a first stop end and a second stop end, a control unit that instructs the oscillation drive unit to oscillate the fan back and forth between the first stop end and the second stop end, and an operation unit that accepts an operation to change the first stop end and the second stop end. The control unit sets a cancel angle between the first stop end and the stop end, and if the operating unit accepts a first operation before the fan reaches the cancel angle while the fan is rotating from the first stop end toward the second stop end, the control unit stores the angle of the fan when the first operation was accepted as the third stop end, and if the operating unit accepts a second operation while the fan is rotating toward the second stop end after accepting the first operation, the control unit stores the angle of the fan when the second operation was accepted as the fourth stop end, and the control unit instructs the swing drive unit to change the range of the fan's reciprocating swing motion from between the first stop end and the second stop end to between the third stop end and the fourth stop end, and if the operating unit accepts the first operation after the fan reaches the cancel angle while the fan is rotating from the first stop end toward the second stop end, the control unit cancels the first operation.

[0008] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc., are also valid aspects of the present disclosure. [Effects of the Invention]

[0009] According to the present disclosure, the angle of the reciprocating swing motion can be easily and freely set. [Brief explanation of the drawings]

[0011] Before describing the present disclosure in detail, a problem underlying the present disclosure will be described. A first embodiment of the present disclosure relates to a blower capable of reciprocating oscillating motion of a fan in the left-right or up-down direction. The blower is, for example, an electric fan or a circulator. Generally, the angle of oscillation of the fan is set by a user. At that time, a start point and an end point of the reciprocating oscillating motion are set. The start point and the end point of the reciprocating oscillating motion correspond to two points at both ends of the reciprocating oscillating motion.

[0012] However, when the blower determines two new points during a reciprocating swing motion at a preset angle, if the user wants to change the range of the reciprocating swing motion to a wider range than the set range of the reciprocating swing motion, an operation to maximize the set range of the reciprocating swing motion is required, which increases the number of operations performed by the user.

[0013] In addition, the user must input the start and end points to set the angle of the swing, but if the start point is input but the end point is not input, only the start point is stored and held in the memory unit. If the user forgets that they have input the start point and inputs the start point at a different time, it will actually be considered that they have input the end point, and the swing angle desired by the user will not be set.

[0014] Furthermore, while it is convenient for the user to freely determine the range of reciprocating oscillation, the load on the reciprocating oscillation motor may increase depending on the position determined by the user, which may cause malfunctions or reduce the durability of the motor or the product.

[0015] 1(a)-(c) show the external appearance of the blower device 100. FIG. 1(a) is a perspective view of the blower device 100, FIG. 1(b) is a front view of the blower device 100, and FIG. 1(c) is a top view of the blower device 100. The blower device 100 is, for example, a fan. The base 10 is disposed at the bottom of the blower device 100 and is supported on a support surface such as a floor. The base 10 has a plate-like or cylindrical shape and is provided with an operating unit 12 and a support column 14 on its top surface. The operating unit 12 is a button or dial that can be operated by the user, and the user inputs instructions for operating the blower device 100 by operating the operating unit 12. The support column 14 has a cylindrical shape and extends upward from the base 10. The upper portion of the support column 14 is connected to a sliding member 20. The operation unit 12 may be a remote controller that can be operated remotely, and further, the operation unit 12 on the base 10 may be used in combination with a remote controller.

[0016] The sliding unit 20 also has a cylindrical shape and extends upward from the support 14. The sliding unit 20 connects the drive housing 22 to its upper portion and rotatably supports the drive housing 22. The fan 30 is connected to the front portion of the sliding unit 20. The drive housing 22 houses a direct current (DC) motor for rotating the fan 30, a first stepping motor for causing the fan 30 to perform a lateral swing reciprocating motion about a lateral swing rotation axis R, and a second stepping motor for causing the fan 30 to perform a vertical swing reciprocating motion about a vertical swing rotation axis S. The first and second stepping motors are collectively referred to as stepping motors. Here, the lateral swing rotation axis R is an axis that extends vertically along the support 14 or the sliding unit 20, and the vertical swing rotation axis S is an axis that extends along the support surface that supports the base 10.

[0017] 2(a)-(b) show the definitions of angles in the reciprocating oscillating motion of the blower device 100. Like FIG. 1(c), FIG. 2(a) shows a top view of the blower device 100. The drive housing 22 and fan 30 of the blower device 100 oscillate back and forth around the left-right oscillating rotation axis R. If the central angle in the reciprocating oscillating motion is called "front," the angle when rotated 90° to the left from the front is called "left," and the angle when rotated 90° to the right from the front is called "right."

[0018] Additionally, a direction vector T is defined for the drive housing 22 or the fan 30. When the drive housing 22 and the fan 30 face forward, the direction vector T is a vector that coincides with the front, and rotates together with the rotation of the drive housing 22 and the fan 30. In the following explanation, angles are described as the direction in which the direction vector T faces. Additionally, when the counterclockwise direction is defined as the first direction D1, the clockwise direction is defined as the second direction D2.

[0019] The first physical limit end 200 indicates the physical limit angle at which the drive housing 22 and fan 30 can rotate to the left, and the second physical limit end 202 indicates the physical limit angle at which the drive housing 22 and fan 30 can rotate to the right. As an example, the first physical limit end 200 is an angle of 20° rotated from the left in the first direction D1, and the second physical limit end 202 is an angle of 160° rotated from the left in the first direction D1. Therefore, the physical limit range 204, which is the angle between the first physical limit end 200 and the second physical limit end 202, is 140°.

[0020] The first swing limit end 210 indicates the limit angle at which the drive housing 22 and the fan 30 can rotate to the left when the blower device 100 oscillates back and forth, and the second swing limit end 212 indicates the limit angle at which the drive housing 22 and the fan 30 can rotate to the right when the blower device 100 oscillates back and forth. In other words, the left-right swing drive unit 64 can swing the fan 30 back and forth between the first swing limit end 210 and the second swing limit end 212. As an example, the first swing limit end 210 is an angle of 10° rotation in the first direction D1 from the first physical limit end 200, and the second swing limit end 212 is an angle of 130° rotation in the first direction D1 from the first physical limit end 200. Therefore, the swing limit range 214, which is the angle between the first swing limit end 210 and the second swing limit end 212, is "120°".

[0021] The first cancellation angle 220 indicates a reference angle for canceling a user input when rotating in the second direction D2, and the second cancellation angle 222 indicates a reference angle for canceling a user input when rotating in the first direction D1. A first cancellation range 224 is defined as a range for canceling a user input when rotating in the second direction D2 between the first swing limit end 210 and the first cancellation angle 220. A second cancellation range 226 is defined as a range for canceling a user input when rotating in the first direction D1 between the second swing limit end 212 and the second cancellation angle 222. Cancellation of a user input will be described later. As an example, the first cancellation angle 220 is the angle obtained by rotating 10° in the first direction D1 from the first swing limit end 210, and the first cancellation range 224 is 10°. Further, the second cancellation angle 222 is an angle obtained by rotating "10°" from the second swing limit end 212 in the second direction D2, and the second cancellation range 226 is "10°".

[0022] Up until now, the first physical limit end 200, etc. has been arranged on the left side, and the second physical limit end 202, etc. has been arranged on the right side. These correspondences are merely examples, and are not intended to be limiting. Therefore, the first physical limit end 200, etc. may be arranged on the right side, and the second physical limit end 202, etc. may be arranged on the left side.

[0023] 2(b) shows a side view from the right side of the blower device 100. The drive housing 22 and fan 30 of the blower device 100 oscillate back and forth around the vertical oscillating rotation axis S. If the angle parallel to the horizontal plane is called "front," the angle when rotated 90° upward from the front is called "up," and the angle in the opposite direction from the front is called "rear."

[0024] Also, a direction vector T is defined for the drive housing 22 or the fan 30. As before, the direction vector T is a vector that coincides with the front when the drive housing 22 and the fan 30 face forward, and rotates together with the rotation of the drive housing 22 and the fan 30. In the following explanation, angles are explained as the direction in which the direction vector T faces. Also, when the upward direction is defined as the third direction D3, the downward direction is defined as the fourth direction D4.

[0025] The first physical limit end 200 indicates the physical limit angle at which the drive housing 22 and fan 30 can rotate downward, and the second physical limit end 202 indicates the physical limit angle at which the drive housing 22 and fan 30 can rotate upward. As an example, the first physical limit end 200 is an angle rotated 10° in the fourth direction D4 from the front, and the second physical limit end 202 is an angle rotated 10° in the third direction D3 from the top. Therefore, the physical limit range 204, which is the angle between the first physical limit end 200 and the second physical limit end 202, is 110°.

[0026] The first swing limit end 210 indicates the limit angle at which the drive housing 22 and the fan 30 can rotate downward when the blower device 100 oscillates back and forth, and the second swing limit end 212 indicates the limit angle at which the drive housing 22 and the fan 30 can rotate upward (rearward) when the blower device 100 oscillates back and forth. As an example, the first swing limit end 210 is an angle facing forward, and the second swing limit end 212 is an angle facing upward (rear). Therefore, the swing limit range 214, which is the angle between the first swing limit end 210 and the second swing limit end 212, is "90°."

[0027] The first cancellation angle 220 indicates a reference angle for canceling a user input when rotating in the fourth direction D4, and the second cancellation angle 222 indicates a reference angle for canceling a user input when rotating in the third direction D3. A first cancellation range 224 is defined as a range for canceling a user input when rotating in the fourth direction D4 between the first swing limit end 210 and the first cancellation angle 220. A second cancellation range 226 is defined as a range for canceling a user input when rotating in the third direction D3 between the second swing limit end 212 and the second cancellation angle 222. As an example, the first cancellation angle 220 is the angle obtained by rotating 10° in the third direction D3 from the first swing limit end 210, and the first cancellation range 224 is 10°. Further, the second cancellation angle 222 is an angle obtained by rotating "10°" from the second swing limit end 212 in the fourth direction D4, and the second cancellation range 226 is "10°".

[0028] Up until now, the first physical limit end 200, etc. has been arranged on the front side, and the second physical limit end 202, etc. has been arranged on the upper side (rear side). These correspondences are merely examples, and are not limited to these. Therefore, the first physical limit end 200, etc. may be arranged on the upper side (rear side), and the second physical limit end 202, etc. may be arranged on the front side.

[0029] 3 shows the configuration of the blower device 100. The blower device 100 includes an operation unit 12, a control unit 50, a drive unit 60, and a memory unit 70. The control unit 50 includes a fan control unit 52, a left-right swing control unit 54, and a up-down swing control unit 56, and the drive unit 60 includes a fan drive unit 62, a left-right swing drive unit 64, and a up-down swing drive unit 66. As described above, the operation unit 12 is a user interface in the form of buttons or dials that can be operated by the user. The operation unit 12 outputs inputs input by user operations to the control unit 50.

[0030] The control unit 50 controls the operation of the blower 100. For example, the control unit 50 operates the blower 100 in response to an input received from the operation unit 12. The control unit 50 is connected to the drive unit 60 and the memory unit 70. The fan drive unit 62 of the drive unit 60 rotates the fan 30 (not shown). The fan drive unit 62 corresponds to the DC motor described above, and known technology is used for the DC motor. The fan drive unit 62 is connected to the fan control unit 52, and the fan control unit 52 controls the rotation of the fan 30 by the fan drive unit 62.

[0031] The left-right swing drive unit 64 causes the fan 30 to swing back and forth in the left-right direction. The left-right swing drive unit 64 corresponds to the first stepping motor described above. The stepping motor is a motor that is driven by applying a DC pulse voltage, and the angle of rotation is adjusted by adjusting the pulse voltage. Hereinafter, the pulse voltage will be referred to as a control signal. The left-right swing drive unit 64 is connected to the left-right swing control unit 54, and the left-right swing control unit 54 adjusts the control signal to control the angle of the left-right swing reciprocating motion caused by the left-right swing drive unit 64.

[0032] The vertical swing drive unit 66 causes the fan 30 to swing back and forth in the vertical direction. The vertical swing drive unit 66 corresponds to the second stepping motor described above. The second stepping motor is configured in the same manner as the first stepping motor. The vertical swing drive unit 66 is connected to the vertical swing control unit 56, and the vertical swing control unit 56 adjusts the control signal to control the vertical swing drive unit 66 to swing back and forth. top and bottom The angle of the directional swing reciprocating motion is controlled.

[0033] The storage unit 70 is a semiconductor memory, a non-volatile memory, or a storage medium, and is capable of storing digital data. Examples of the semiconductor memory include a random access memory (RAM), a read-only memory (ROM), a flash memory, and a synchronous dynamic RAM (SDRAM). Examples of the non-volatile memory include an erasable programmable read-only memory (EPROM) and an electrically erasable programmable read-only memory (EEPROM). Examples of the storage medium include a solid state drive (SSD) and a hard disk drive (HDD). The storage unit 70 stores information used in the control of the control unit 50. An example of the information stored in the storage unit 70 is the value of the first swing limit end 210, etc., that is, the value of the control signal corresponding to the first swing limit end 210, etc.

[0034] The basic operations of the blower device 100 will be explained below in the order of (1) to (8). (1) The power cord (not shown) of the fan device 100 is plugged into an outlet (not shown). This causes the fan device 100 to be energized. (2) When the user operates operation unit 12 to turn on the power of blower device 100, fan control unit 52 rotates fan drive unit 62, causing fan 30 to rotate. As a result, air is blown by blower device 100. At this time, left-right swing control unit 54 and up-down swing control unit 56 are not operating, so fan 30 faces forward in the left-right and up-down directions.

[0035] (3) When the user operates the operation unit 12 and inputs a command for left-right oscillation, the left-right oscillation control unit 54 performs calibration for the left-right oscillation. The left-right oscillation control unit 54 rotates the fan 30 to the first physical limit end 200 while changing the control signal. The left-right oscillation control unit 54 acquires the value of the control signal when the fan 30 faces the first physical limit end 200. In the control of the blower 100, the first physical limit end 200 is defined as "0°," so the memory unit 70 stores the angle "0°" of the first physical limit end 200 and the value of the control signal at that time in association with each other.

[0036] The left-right swing control unit 54 changes the control signal to rotate the fan 30 to the second physical limit end 202. The left-right swing control unit 54 acquires the value of the control signal when the fan 30 faces the second physical limit end 202. When the first physical limit end 200 is defined as "0°," the second physical limit end 202 is "140°," so the storage unit 70 stores the angle of the second physical limit end 202, "140°," in association with the value of the control signal at that time.

[0037] (4) Based on the control signal value corresponding to "0°" and the control signal value corresponding to "140°," the left / right swing control unit 54 calculates the control signal value corresponding to the angle "10°" of the first swing limit end 210 and the control signal value corresponding to the angle "130°" of the second swing limit end 212. The memory unit 70 stores the angle "10°" of the first swing limit end 210 and the control signal value at that time in association with each other. The memory unit 70 also stores the angle "120°" of the second swing limit end 212 and the control signal value at that time in association with each other.

[0038] Similarly, the left / right swing control unit 54 calculates the value of the control signal corresponding to the first cancellation angle 220 of "20°" and the value of the control signal corresponding to the second cancellation angle 222 of "120°". The storage unit 70 stores the first cancellation angle 220 of "20°" in association with the value of the control signal at that time. The storage unit 70 also stores the second cancellation angle 222 of "120°" in association with the value of the control signal at that time.

[0039] (5) The left / right swing control unit 54 calculates the center value of the left / right swing reciprocating movement, that is, the value of the control signal corresponding to the aforementioned "forward," based on the value of the control signal corresponding to "0°" and the value of the control signal corresponding to "140°." For example, the left / right swing control unit 54 calculates the value of the control signal corresponding to "forward" by halving the difference between the value of the control signal corresponding to "0°" and the value of the control signal corresponding to "140°." The left / right swing control unit 54 stores the value of the control signal corresponding to "forward."

[0040] (6) After the calibration is completed, the user operates the operation unit 12 to input the default swing range of the left and right swing reciprocating motion. For example, 30°, 60°, 90°, and 120° are predefined as the default swing range, and the user selects one of these. The default swing range of "30°" can be set to any value between "55°" and "80°". 5 This is the range of rotation of 15° to the left and 15° to the right, with 70° as the center.

[0041] The default swing range of "60°" is defined as "40°" to "100°". This is a range of rotation of "30°" to the left and "30°" to the right around "70°". The default swing range of "90°" is defined as "25°" to "115°". This is a range of rotation of "45°" to the left and "45°" to the right around "70°". The default swing range of "120°" is defined as the range from the first swing limit end 210 to the second swing limit end 212.

[0042] (7) When the left / right swing control unit 54 receives input from the operation unit 12, it instructs the left / right swing drive unit 64 to perform left / right swing reciprocating motion within the received default swing range, and the left / right swing drive unit 64 causes the fan 30 to perform left / right swing reciprocating motion within the default swing range. (8) The user operates operation unit 12 to input a command to stop the reciprocating left-right oscillation. Upon receiving the input from operation unit 12, left-right oscillation control unit 54 instructs left-right oscillation drive unit 64 to stop the reciprocating left-right oscillation at the angle at which the input was received, and left-right oscillation drive unit 64 stops the reciprocating left-right oscillation of fan 30 at the angle at which the input was received.

[0043] Although the above description is directed to left-right reciprocating movement, similar processing is performed for up-down reciprocating movement. In this case, in (3), when the user operates the operation unit 12 and inputs a command for up-down reciprocating movement, the up-down reciprocating control unit 56 executes calibration for the up-down reciprocating movement. In addition, in (6), the default reciprocating movement range is predefined, for example, to 45° or 90°. Note that the timing of calibration may be, for example, when the power is turned on in (2).

[0044] In the case of (7) reciprocating left and right swing within the default swing range, the user can freely change the angle of the reciprocating left and right swing by operating the operation unit 12. In this case, the swing range can be set to any value different from the default swing range. Below, we will explain (9) changing the angle of the reciprocating left and right swing when the default swing range is 30°, 60°, or 90°, i.e., when the default swing range is narrower than the swing limit range 214, and (10) changing the angle of the reciprocating left and right swing when the default swing range is 120°, i.e., when the default swing range is equal to the swing limit range 214. Similar processing is also possible for reciprocating up and down swing, but a description thereof will be omitted here.

[0045] (9) Change the angle of the left and right swing when the default swing range is 30°, 60°, or 90° 4(a)-(d) show an overview of the operation of the blower device 100. FIG. 4(a) shows a case in which the fan 30 performs left-right oscillation reciprocating motion within the default oscillation range of "60°" in (7) above. The left-right oscillation control unit 54 sets a first oscillation stop end 230 and a second oscillation stop end 232 between the first oscillation limit end 210 and the second oscillation limit end 212. Here, the first oscillation stop end 230 is closer to the first oscillation limit end 210 than the second oscillation stop end 232, and the second oscillation stop end 232 is closer to the second oscillation limit end 212 than the first oscillation stop end 230.

[0046] The angle between the first swing stop end 230 and the second swing stop end 232 is the first swing setting range 240. The first swing setting range 240 corresponds to the default swing range described above. Here, the first swing stop end 230 is 40°, the second swing stop end 232 is 100°, and the first swing setting range 240 is 60°. The left-right swing control unit 54 instructs the left-right swing drive unit 64 to swing the fan 30 back and forth between the first swing stop end 230 and the second swing stop end 232.

[0047] 4(b) shows a state in which the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1). The operation unit 12 receives an operation from the user to change the first swing stop end 230 and the second swing stop end 232. In FIG. 4(b), the angle when the operation unit 12 receives a first operation while the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1) is shown as the third swing stop end 234.

[0048] Figure 4(c) shows the operation following Figure 4(b). When the operation unit 12 receives a first operation while the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1), the left / right swing control unit 54 stores the above-mentioned third swing stop end 234 in the memory unit 70. The third swing stop end 234 stored in the memory unit 70 is the value of the control signal at the third swing stop end 234.

[0049] The left / right swing control unit 54 instructs the left / right swing drive unit 64 to change the range of the reciprocating swing motion of the fan 30 from between the first swing stop end 230 and the second swing stop end 232 to between the first swing limit end 210 and the second swing limit end 212. This corresponds to expanding the first swing setting range 240 from "60°" to the swing limit range 214 of "120°".

[0050] This is to expand the range in which a second operation can be accepted so that the fan 30 can oscillate back and forth in areas outside the first oscillation setting range 240. If the first oscillation setting range 240 could only be changed within "60°," the user would need to change the default oscillation range from "60°" to "120°" and then set a new oscillation range. This increases the user's workload. To minimize this increase in user workload, in this embodiment, once the first operation is accepted, the first oscillation setting range 240 is automatically expanded to the oscillation limit range 214, making it possible to accept a second operation even outside the first oscillation setting range 240.

[0051] Figure 4(d) shows the operation following Figure 4(c). If the operation unit 12 receives a second operation after receiving a first operation while the fan 30 is rotating toward the second swing limit end 212 (first direction D1), the left / right swing control unit 54 stores the angle of the fan 30 when the second operation was received in the memory unit 70 as the fourth swing stop end 236. The fourth swing stop end 236 stored in the memory unit 70 is the value of the control signal at the fourth swing stop end 236.

[0052] When the fourth swing stop end 236 is stored in the memory unit 70, the left / right swing control unit 54 determines to change the range of the reciprocating swing of the fan 30 from between the first swing stop end 230 and the second swing stop end 232 to between the third swing stop end 234 and the fourth swing stop end 236. Since the range between the third swing stop end 234 and the fourth swing stop end 236 is designated as the second swing setting range 242, the above change corresponds to changing the first swing setting range 240 to the second swing setting range 242. The left / right swing control unit 54 instructs the left / right swing drive unit 64 to swing back and forth between the third swing stop end 234 and the fourth swing stop end 236.

[0053] 5(a)-(d) show an overview of the operation of the blower device 100. FIG. 5(a) also shows the operation following FIG. 4(c), but in a different state from FIG. 4(d). If the operation unit 12 accepts a first operation, but the operation unit 12 does not accept a second operation and the fan 30 reaches the second oscillation limit end 212, the left-right oscillation control unit 54 deletes the third oscillation stop end 234 stored in the memory unit 70. In other words, even if a first operation is performed while the fan 30 is rotating in the first direction D1, if a second operation is not performed before the rotation of the first direction D1 ends, the first operation is canceled. In other words, even if the user performs a first operation but does not perform a second operation, the first operation is automatically canceled. Therefore, even if the first operation is no longer necessary, the user does not need to perform an operation to cancel the first operation. This improves user operability.

[0054] FIG. 5(b) shows the operation following FIG. 5(a). As described above, when the fan 30 reaches the second swing limit end 212, the left-right swing control unit 54 deletes the third swing stop end 234 stored in the memory unit 70. Subsequently, the left-right swing control unit 54 instructs the left-right swing drive unit 64 to rotate the fan 30 in the second direction D2. At this time, the left-right swing control unit 54 rotates the fan 30 from the second swing limit end 212 to the second swing stop end 232, and then determines to change the range of the reciprocating swing motion of the fan 30 from between the first swing limit end 210 and the second swing limit end 212 to between the first swing stop end 230 and the second swing stop end 232. This corresponds to returning the swing limit range 214 to the first swing setting range 240. The left / right swing control unit 54 rotates from the second swing limit end 212 to the second swing stop end 232, and then instructs the left / right swing drive unit 64 to perform a reciprocating swing motion between the first swing stop end 230 and the second swing stop end 232.

[0055] When the fan 30 is rotating in the second direction D2 from the second swing limit end 212, the operating unit 12 receives an operation from the user to change the first swing stop end 230 and the second swing stop end 232. In Figure 5(b), the angle when the operating unit 12 receives the first operation while the fan 30 is rotating in the second direction D2 is shown as the fourth swing stop end 236.

[0056] Figure 5(c) shows the operation following Figure 5(b). When the operation unit 12 receives a first operation while the fan 30 is rotating from the second limit end toward the first swing stop end 230 (second direction D2), the left / right swing control unit 54 stores the aforementioned fourth swing stop end 236 in the memory unit 70. The fourth swing stop end 236 stored in the memory unit 70 is the value of the control signal at the fourth swing stop end 236.

[0057] The left / right swing control unit 54 instructs the left / right swing drive unit 64 to change the range of the reciprocating swing motion of the fan 30 from between the first swing stop end 230 and the second swing stop end 232 to between the first swing limit end 210 and the second swing limit end 212. This corresponds to expanding the first swing setting range 240 from "60°" to the swing limit range 214 of "120°".

[0058] Figure 5(d) shows the operation following Figure 5(c). If the operation unit 12 receives a second operation after receiving a first operation while the fan 30 is rotating toward the first swing limit end 210 (second direction D2), the left / right swing control unit 54 stores the angle of the fan 30 when the second operation was received in the memory unit 70 as the third swing stop end 234. The third swing stop end 234 stored in the memory unit 70 is the value of the control signal at the third swing stop end 234.

[0059] When the third swing stop end 234 is stored in the memory unit 70, the left / right swing control unit 54 determines to change the range of the reciprocating swing of the fan 30 from between the first swing stop end 230 and the second swing stop end 232 to between the third swing stop end 234 and the fourth swing stop end 236. Since the range between the third swing stop end 234 and the fourth swing stop end 236 is designated as the second swing setting range 242, the above change is equivalent to changing the first swing setting range 240 to the second swing setting range 242. The left / right swing control unit 54 instructs the left / right swing drive unit 64 to swing back and forth between the third swing stop end 234 and the fourth swing stop end 236.

[0060] On the other hand, if the operation unit 12 accepts a first operation and then the fan 30 reaches the first oscillation limit end 210 without accepting a second operation from the operation unit 12, the horizontal oscillation control unit 54 deletes the fourth oscillation stop end 236 stored in the memory unit 70. In other words, even if a first operation is performed while the fan 30 is rotating in the second direction D2, the first operation is canceled unless a second operation is performed before the rotation in the second direction D2 ends. Subsequently, the horizontal oscillation control unit 54 instructs the horizontal oscillation drive unit 64 to rotate the fan 30 in the first direction D1. At this time, the left / right swing control unit 54 rotates the fan 30 from the first swing limit end 210 to the first swing stop end 230, and then determines to change the range of the reciprocating swing of the fan 30 from between the first swing limit end 210 and the second swing limit end 212 to between the first swing stop end 230 and the second swing stop end 232. This corresponds to returning the fan 30 from the swing limit range 214 to the first swing setting range 240. The left / right swing control unit 54 rotates the fan 30 from the first swing limit end 210 to the first swing stop end 230, and then instructs the left / right swing drive unit 64 to swing the fan 30 back and forth between the first swing stop end 230 and the second swing stop end 232.

[0061] (10) Changing the angle of the left and right swing when the default swing range is 120° 6(a)-(d) show an overview of the operation of the blower device 100. FIG. 6(a) shows a case in which the fan 30 performs left-right oscillation reciprocating motion within the default oscillation range of "120°" in the above-mentioned (7). The left-right oscillation control unit 54 sets a first oscillation stop end 230 and a second oscillation stop end 232. The angle between the first oscillation stop end 230 and the second oscillation stop end 232 is the first oscillation setting range 240. The first oscillation setting range 240 corresponds to the above-mentioned default oscillation range. In this example, the first oscillation stop end 230 is "10°," the second oscillation stop end 232 is "130°," and the first oscillation setting range 240 is "120°." That is, the first swing stop end 230 and the first swing limit end 210 coincide, the second swing stop end 232 and the second swing limit end 212 also coincide, and the first swing setting range 240 and the swing limit range 214 also coincide. The left-right swing control unit 54 instructs the left-right swing drive unit 64 to swing the fan 30 back and forth between the first swing stop end 230 and the second swing stop end 232.

[0062] The left / right swing control unit 54 sets a first cancellation angle 220 and a second cancellation angle 222 between a first swing stop end 230 and a second swing stop end 232. The first cancellation angle 220 is closer to the first swing stop end 230 than the second cancellation angle 222, and the second cancellation angle 222 is closer to the second swing stop end 232 than the first cancellation angle 220. The angle between the first swing stop end 230 and the first cancellation angle 220 is defined as a first cancellation range 224, and the angle between the second swing stop end 232 and the second cancellation angle 222 is defined as a second cancellation range 226. Here, the first cancellation angle 220 is 20°, and the second cancellation angle 222 is 100°. Therefore, both the first cancellation range 224 and the second cancellation range 226 are 10°.

[0063] When the fan 30 is rotating in the first direction D1, the left / right swing control unit 54 enables the second cancellation range 226 and disables the first cancellation range 224. When the fan 30 is rotating in the second direction D2, the left / right swing control unit 54 enables the first cancellation range 224 and disables the second cancellation range 226. With these settings, if the operating unit 12 receives a first operation in the second cancellation range 226 while the fan 30 is rotating in the first direction D1, the left / right swing control unit 54 cancels the first operation. When the operating unit 12 receives a first operation in the first cancellation range 224 while the fan 30 is rotating in the second direction D2, the left / right swing control unit 54 cancels the first operation.

[0064] If the moment of inertia of the stepping motor mechanism is smaller than the allowable moment of inertia of the stepping motor, no problem occurs. However, if the moment of inertia of the stepping motor mechanism is larger than the allowable moment of inertia of the stepping motor, the stepping motor may become difficult to stop instantly, and a large torque may be applied during an instantaneous stop, potentially damaging the mechanism. To prevent this from occurring, a second cancellation range 226 is set when the motor rotates in the first direction D1, and a first cancellation range 224 is set when the motor rotates in the second direction D2.

[0065] 6(b) shows a state in which the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1). The operation unit 12 receives an operation from the user to change the first swing stop end 230 and the second swing stop end 232. In FIG. 6(b), the angle when the operation unit 12 receives a first operation while the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1) is shown as the third swing stop end 234.

[0066] When the operation unit 12 receives the first operation, the left / right swing control unit 54 stores the third swing stop end 234 in the memory unit 70. The third swing stop end 234 stored in the memory unit 70 is the value of the control signal at the third swing stop end 234.

[0067] Figure 6(c) shows the operation following Figure 6(b). If the operation unit 12 receives a second operation after receiving a first operation while the fan 30 is rotating toward the second swing stop end 232 (first direction D1), the left / right swing control unit 54 stores the angle of the fan 30 at the time the second operation was received in the memory unit 70 as the fourth swing stop end 236. The fourth swing stop end 236 stored in the memory unit 70 is the value of the control signal at the fourth swing stop end 236. The left / right swing control unit 54 instructs the left / right swing drive unit 64 to perform a reciprocating swing motion between the third swing stop end 234 and the fourth swing stop end 236.

[0068] FIG. 6(d) also shows the operation following FIG. 6(b), but the position of the fourth swing stop end 236 is different from that in FIG. 6(c). In FIG. 6(d), the operating unit 12 accepts a second operation in the second cancel range 226. As described above, if the operating unit 12 accepts a first operation in the second cancel range 226 while the fan 30 is rotating in the first direction D1, the horizontal swing control unit 54 cancels the first operation. However, in this case, because the operating unit 12 accepts a second operation in the second cancel range 226, the horizontal swing control unit 54 does not cancel the second operation. Therefore, as in the case of FIG. 6(c), the horizontal swing control unit 54 instructs the horizontal swing drive unit 64 to perform a reciprocating swing motion between the third swing stop end 234 and the fourth swing stop end 236.

[0069] 7(a)-(d) show an overview of the operation of the blower 100. FIG. 7(a) is another example of FIG. 6(b). When the fan 30 is rotating from the first swing stop end 230 toward the second swing stop end 232 (first direction D1) and the operating unit 12 receives a first operation after the fan 30 reaches the second cancel angle 222, the left / right swing control unit 54 cancels the first operation. In FIG. 7(a), the input to the third swing stop end 234 is canceled.

[0070] Figure 7(b) shows the operation following Figure 6(b). If the operating unit 12 accepts a first operation, but then the operating unit 12 does not accept a second operation and the fan 30 reaches the second oscillation stop end 232, the left / right oscillation control unit 54 deletes the third oscillation stop end 234 stored in the memory unit 70. In other words, even if the first operation is performed while the fan 30 is rotating in the first direction D1, the first operation is canceled unless a second operation is performed before the rotation in the first direction D1 ends.

[0071] Subsequently, the horizontal swing control unit 54 instructs the horizontal swing drive unit 64 to rotate the fan 30 in the second direction D2. While the fan 30 is rotating from the second swing stop end 232 to the second direction D2, the operation unit 12 receives an operation from the user to change the first swing stop end 230 and the second swing stop end 232. In FIG. 7(b), the angle when the operation unit 12 receives the first operation while the fan 30 is rotating in the second direction D2 is shown as the fourth swing stop end 236. The fourth swing stop end 236 is included in the second cancellation range 226. However, even if the operation unit 12 receives the first operation within the second cancellation range 226 while the fan 30 is rotating in the second direction D2, the horizontal swing control unit 54 does not cancel the first operation. Therefore, the horizontal swing control unit 54 stores the fourth swing stop end 236 in the memory unit 70. The fourth swing stop end 236 stored in the storage unit 70 is the value of the control signal at the fourth swing stop end 236 .

[0072] Figure 7(c) shows the operation following Figure 7(b). If the operation unit 12 receives a second operation after receiving a first operation while the fan 30 is rotating toward the first swing stop end 230 (second direction D2), the left / right swing control unit 54 stores the angle of the fan 30 when the second operation was received in the memory unit 70 as the third swing stop end 234. The third swing stop end 234 stored in the memory unit 70 is the value of the control signal at the third swing stop end 234.

[0073] When the third swing stop end 234 is stored in the memory unit 70, the left / right swing control unit 54 determines to change the range of the reciprocating swing of the fan 30 from between the first swing stop end 230 and the second swing stop end 232 to between the third swing stop end 234 and the fourth swing stop end 236. Since the range between the third swing stop end 234 and the fourth swing stop end 236 is designated as the second swing setting range 242, the above change is equivalent to changing the first swing setting range 240 to the second swing setting range 242. The left / right swing control unit 54 instructs the left / right swing drive unit 64 to swing back and forth between the third swing stop end 234 and the fourth swing stop end 236.

[0074] 7(d), when the fan 30 is rotating in the second direction D2 from the second swing stop end 232 in FIG. 7(b), the operating unit 12 receives an operation from the user to change the first swing stop end 230 and the second swing stop end 232. Here, the angle when the operating unit 12 receives the first operation while the fan 30 is rotating in the second direction D2 is shown as the fourth swing stop end 236. The fourth swing stop end 236 is included in the first cancellation range 224. When the operating unit 12 receives the first operation within the first cancellation range 224 while the fan 30 is rotating in the second direction D2, the left / right swing control unit 54 cancels the first operation.

[0075] This configuration can be realized in hardware terms by any computer's CPU (Central Processing Unit), memory, and other LSIs (Large Scale Integration), and in software terms by programs loaded into memory, but here we depict functional blocks realized by the cooperation of these. Therefore, those skilled in the art will understand that these functional blocks can be realized in various forms by hardware alone or a combination of hardware and software.

[0076] The operation of the blower device 100 configured as described above will now be described. Figure 8 is a flowchart showing the operating procedure of the blower device 100. The blower device 100 is plugged into an outlet (S10). The blower device 100 performs a reciprocating oscillation motion with default oscillation settings (S12). The blower device 100 performs calibration (S14). The blower device 100 changes the oscillation settings (S16). The blower device 100 performs a reciprocating oscillation motion with the changed oscillation settings (S18).

[0077] FIG. 9 is a flowchart showing the change procedure performed by the blower device 100. This corresponds to the process when the default swing range is 30°, 60°, and 90°. The operation unit 12 accepts a first change operation (S50). The left-right swing control unit 54 changes the range of the reciprocating swing operation to the swing limit range 214 (S52). The left-right swing control unit 54 stores the angle at which the change was accepted as the third swing stop end 234 (S54). If the operation unit 12 accepts a second change operation before the second swing limit end 212 is reached (Y in S56), the left-right swing control unit 54 stores the angle at which the change was accepted as the fourth swing stop end 236 (S54). The left-right swing control unit 54 changes the first swing setting range 240 to the second swing setting range 242 (S60). If the operation unit 12 does not accept the second change operation by the time of the second swing limit end 212 (N in S56), the left / right swing control unit 54 deletes the third swing stop end 234 (S62).

[0078] FIG. 10 is a flowchart showing another change procedure performed by the blower device 100. This corresponds to the process when the default swing range is 120°. The operation unit 12 accepts a first change operation (S100). If the accepted position is outside the second cancel range 226 (Y in S102), the left / right swing control unit 54 stores the accepted angle as the third swing stop end 234 (S104). If the operation unit 12 accepts a second change operation before the second swing stop end 232 (Y in S106), the left / right swing control unit 54 stores the accepted angle as the fourth swing stop end 236 (S108). The left / right swing control unit 54 changes the first swing setting range 240 to the second swing setting range 242 (S110). If the operation unit 12 does not accept the second change operation by the second swing stop end 232 (N in S106), the left / right swing control unit 54 deletes the third swing stop end 234 (S112). If the accepted position is not outside the second cancellation range 226 (N in S102), the left / right swing control unit 54 cancels the first change operation (S114).

[0079] Up until now, the blower 100 has been described as a fan, but the blower 100 may also be a circulator. Figures 11(a)-(c) show the external appearance of the blower 100 and the definition of the angles in the reciprocating oscillating motion of the blower 100. Figure 11(a) shows a front view of the blower 100. The blower 100 includes a base 10 and a fan 30, as before. The fan 30 is rotatable. The fan 30 is also capable of reciprocating oscillating motion in the left-right direction about a left-right oscillating rotation axis R. Furthermore, the fan 30 is also capable of reciprocating oscillating motion in the up-down direction about a vertical oscillating rotation axis S.

[0080] FIG. 11(b) shows a top view of the blower device 100. The fan 30 of the blower device 100 oscillates back and forth about the oscillating rotation axis R. In FIG. 11(b), a first physical limit end 200, a second physical limit end 202, a first oscillation limit end 210, a second oscillation limit end 212, a first cancellation angle 220, and a second cancellation angle 222 are defined, as before. Furthermore, the respective values of the first physical limit end 200, the second physical limit end 202, the first oscillation limit end 210, the second oscillation limit end 212, the first cancellation angle 220, and the second cancellation angle 222 may remain the same as before.

[0081] FIG. 11(c) shows a side view of the blower device 100 from the right side. The fan 30 of the blower device 100 oscillates back and forth about the vertical oscillation rotation axis S. In FIG. 11(c), as before, a first physical limit end 200, a second physical limit end 202, a first oscillation limit end 210, a second oscillation limit end 212, a first cancel angle 220, and a second cancel angle 222 are defined. For example, as before, the first physical limit end 200 is an angle rotated 10° from the front in the fourth direction D4, the first oscillation limit end 210 is an angle facing forward, and the first cancel angle 220 is an angle rotated 10° from the first oscillation limit end 210 in the third direction D3.

[0082] Meanwhile, the second physical limit end 202 is an angle obtained by rotating 170° in the third direction D3 from the first physical limit end 200, the second oscillation limit end 212 is an angle obtained by rotating 160° in the third direction D3 from the first physical limit end 200, and the second cancellation angle 222 is an angle obtained by rotating 10° in the fourth direction D4 from the second oscillation limit end 212. Therefore, the angle between the first physical limit end 200 and the second physical limit end 202 is 170°, and the angle between the first oscillation limit end 210 and the second oscillation limit end 212 is 150°. In other words, the up-down oscillation angle of the circulator is larger than that of an electric fan. The processing performed by the circulator is the same as that described above, and therefore will not be described here.

[0083] According to this embodiment, the range of reciprocating oscillation of the fan 30 is expanded when the first operation is accepted, so that it is easy to change the angle to an angle outside the default range. Furthermore, because the angle is easily changed to an angle outside the default range, the angle of the reciprocating oscillation can be easily and freely set. Furthermore, because the default angle is changed to the angle when the first operation is accepted and the angle when the second operation is accepted, the angle of the reciprocating oscillation can be easily and freely set.

[0084] Furthermore, if the fan 30 reaches the second oscillation limit end 212 without accepting a second operation after accepting a first operation, the angle at which the first operation was accepted is deleted, making it possible to easily invalidate the first operation. Furthermore, if the fan 30 reaches the second oscillation limit end 212 without accepting a second operation after accepting a first operation, the angle is returned to the default range, making it possible to easily invalidate the first operation. Furthermore, since the first operation is invalidated even if the user does not perform a cancel operation after accepting the first operation, user operability is improved. Furthermore, since the first operation is invalidated even if the user does not perform a cancel operation after accepting the first operation, it is possible to eliminate the need for a cancel button.

[0085] If a first operation is received within second cancellation range 226 while fan 30 is rotating from first oscillation limit end 210 toward second oscillation limit end 212, the first operation is canceled, thereby preventing the moment of inertia of the stepping motor mechanism from exceeding the allowable moment of inertia of the stepping motor. Furthermore, since the moment of inertia of the stepping motor mechanism is prevented from exceeding the allowable moment of inertia of the stepping motor, it is possible to prevent the stepping motor from becoming difficult to stop instantly. Furthermore, since the moment of inertia of the stepping motor mechanism is prevented from exceeding the allowable moment of inertia of the stepping motor, the torque applied during an instantaneous power outage is reduced, thereby preventing damage to the mechanism. [Example]

[0086] Next, a second embodiment will be described. The second embodiment of the present disclosure relates to the blower device 100, similar to the first embodiment. The second embodiment relates to an additional function for controlling the rotation speed of the fan 30 of the blower device 100, i.e., the air volume. The following description will focus on the differences from the previous embodiments.

[0087] 12 shows the configuration of air blower 100. Air blower 100 includes an operation unit 12, a control unit 50, a drive unit 60, a memory unit 70, and a temperature sensor 80. Control unit 50 also includes a fan control unit 52, a left-right swing control unit 54, a up-down swing control unit 56, an angle acquisition unit 90, and a temperature acquisition unit 92, and drive unit 60 includes a fan drive unit 62, a left-right swing drive unit 64, and a up-down swing drive unit 66.

[0088] The temperature sensor 80 measures the temperature of the space in which the blower 100 is placed. Known technology may be used for the temperature sensor 80, and therefore a description thereof will be omitted here. The temperature sensor 80 outputs information about the measured temperature to the control unit 50. The temperature acquisition unit 92 of the control unit 50 acquires the temperature information from the temperature sensor 80.

[0089] The memory unit 70 stores a table showing the correspondence between temperature and the rotation speed of the fan 30. FIGS. 13(a)-(b) show the data structure of the table stored in the memory unit 70. As shown in FIG. 13(a), the correspondence between temperature and rotation speed is shown as a table. FIG. 13(b) will be described later, returning to FIG. 12. The fan control unit 52 acquires the rotation speed by referring to the table stored in the memory unit 70 based on the temperature acquired by the temperature acquisition unit 92. The fan control unit 52 instructs the fan drive unit 62 to rotate the fan 30 at the acquired rotation speed.

[0090] The angle acquisition unit 90 receives the angle of the reciprocating oscillation of the fan 30 from the up-down oscillation control unit 56. The angle acquisition unit 90 may also receive the angle of the reciprocating oscillation of the fan 30 from the left-right oscillation control unit 54. The memory unit 70 stores a table indicating the correspondence between the angle and the rotation speed of the fan 30. As shown in FIG. 13(b), the correspondence between the angle and the rotation speed is shown as a table. The value of the control signal may also be represented as an angle. Returning to FIG. 12, the fan control unit 52 acquires the rotation speed by referring to the table stored in the memory unit 70 based on the angle acquired by the angle acquisition unit 90. The fan control unit 52 instructs the fan drive unit 62 to rotate the fan 30 at the acquired rotation speed.

[0091] When the air blower 100 is used to dry clothes, if the air volume is constant, clothes, etc. close to the air blower 100 will be well ventilated, but clothes, etc. far from the air blower 100 will be less ventilated. This can result in uneven drying of the clothes. For this reason, the table shows settings that increase the air volume at an angle where clothes, etc. far from the air blower 100 are located compared to the air volume in the direction where clothes, etc. close to the air blower 100 are located.

[0092] According to this embodiment, the rotation speed is changed according to the temperature, so that air can be blown in a manner appropriate for the temperature. In addition, the rotation speed is changed according to the angle of the fan 30, so that uneven drying can be suppressed when the air blower 100 is used to dry clothes, etc.
