  The stand 14 includes a bottom portion 140 in which the lighting device 40 is accommodated, a pedestal portion 141 formed in a circular shape in plan view, and a support column portion 142 that is erected vertically from the rear side from the center of the pedestal portion 141. A casing support part 143 is provided above the support part 142 and rotatably supports the casing 20 in which the fan 11 and the fan motor 12 are housed. The casing 20 houses a fan motor 12 that drives the fan 11 for generating an air flow.

  The casing 20 has a rotation shaft 10 in a substantially horizontal direction (lateral direction), and the casing support portion 143 includes a pair of left and right bearing portions 40 that support the rotation shaft 10. In the casing 20, a swing mechanism unit 30 including a vertical swing motor 31 is provided, and a driving force by the vertical swing motor 31 is applied to the rotary shaft 10 via a plurality of gears such as a reduction gear 32. By transmitting and rotating the casing 20 around the rotation shaft 10, the casing 20 is swung in the vertical direction, and the blowing direction by the fan 11 is changed in the vertical direction.

  The casing support part 143 is configured to be movable in the vertical direction with respect to the support column part 142. By operating a button 144 provided on the support column part 142, the casing support part 143 is moved up and down, and the casing 20 It is configured so that the height can be set. Moreover, the casing support part 143 is pivotally supported by the support | pillar part 142 so that rotation in the left-right direction is possible. Thus, the casing 20 can be swung in the left-right direction, and the blowing direction by the fan 11 can be changed in the left-right direction. The blower device 1 includes a left and right swing motor 145 for rotating the casing support portion 143 around the axial length direction of the support column 142 in order to automatically swing the left and right direction.

  The fan 11 of the blower 1 includes, for example, three blade members and is attached to the output shaft 121 of the fan motor 12. By being driven by the fan motor 12, the fan 11 rotates in a predetermined direction (clockwise as viewed from the front), and generates an air flow on the side opposite to the fan motor 12. That is, in the side view shown in FIG. 2, the air flow generated by the fan 11 is configured to be sent to the left side of the fan 11. Hereinafter, the downstream side in the blowing direction is the front side of the casing 20, and the upstream side in the blowing direction is the rear side of the casing 20.

  The casing 20 includes a motor housing portion 21 in which the fan motor 12 and the vertical swing mechanism portion 30 are provided, a fan guard portion 22 that covers the outer periphery and the rear of the fan 11, and a cover 23 that covers the front of the fan 11. . The motor housing portion 21 and the fan guard portion 22 are integrally formed, and the cover 23 is detachably attached to the fan guard portion 22.

  The motor housing portion 21 includes a first housing portion 211 that houses the fan motor 12 and a second housing portion 212 that houses the swing mechanism portion 30. Further, the blower device 1 according to the first embodiment includes an ion generator 213, and the motor housing unit 21 includes the ion generator 213 in addition to the first storage unit 211 and the second storage unit 212. A third housing portion 214 is provided for housing.

  The first accommodating portion 211 is provided near the front center of the motor housing portion 21 and includes an opening 215 that projects the output shaft 121 of the fan motor 12 toward the fan guard portion 22. The fan motor 12 is fixed in the first housing portion 211 with the output shaft 121 protruding forward from the opening 215.

  The second housing portion 212 is provided in the vicinity of the rear center of the motor housing portion 21 (behind the first housing portion 211), and houses the swing mechanism portion 30 that rotates the casing 20 in the vertical direction. . The rotating shaft 10 of the casing 20 is disposed at a position separated from the fan motor 12 on the side opposite to the fan 11 mounting side (that is, behind the fan motor 12).

  The third housing part 214 is provided on the upper front side of the motor housing part 21 (upper side of the first housing part 211), and houses the ion generator 213 therein. An ion delivery port 216 is provided on the front side of the third housing portion 214. Ions generated from the ion generator 213 are diffused into the fan guard portion 22 through the ion outlet 216 and are carried forward by the air flow accompanying the rotation of the fan 11.

  The fan guard portion 22 has a circular opening edge 221 in front view on the front side, and the cover 23 is configured to be detachably attached through the opening edge 221. Further, the motor housing portion 21 described above is integrally formed on the rear side of the fan guard portion 22. Slits 222 and 223 are provided in the outer peripheral portion and the rear portion of the fan guard portion 22. When the fan 11 is driven, air outside the apparatus is taken into the fan guard portion 22 through the slits 222 and 223. The air flow is generated by the rotation of.

  The cover 23 is formed in a circular shape when viewed from the front, and includes a large number of wind-off members 231, 231, 231,... Provided radially from the center, as shown in FIG. The blower device 1 is configured to change the direction of the wind to be diffused forward and outward by the fan 11 by a wind-cutting member 231 provided on the cover 23 so as to improve straightness in the blowing direction.

  The cover 23 has an opening edge portion 232 having an outer diameter slightly larger than the outer diameter of the opening edge portion 221 of the fan guard portion 22. A plurality of locking grooves are formed in the circumferential direction on the inner peripheral surface of the opening edge 232. Further, the same number of locking projections as the locking grooves are formed on the opening edge portion 221 on the front side of the fan guard portion 22. The user aligns the locking groove on the cover 23 side and the locking projection on the fan guard portion 22 side, inserts the locking groove on the cover 23 side into the locking projection on the fan guard portion 22 side, The cover 23 is attached to the fan guard portion 22 by engaging the both by rotating the 23 in the circumferential direction.

  The cover 23 includes an annular partition wall 233 having an outer diameter smaller than the inner diameter of the cover outer peripheral surface and provided to face the cover outer peripheral surface. As shown in FIG. 1, the inner diameter of the partition wall 233 is configured to be larger than the outer diameter of the fan 11. The air flow generated by the rotation of the fan 11 passes through the inside of the partition wall 233 and is sent out of the blower 1. On the other hand, a gap formed by the fitting portion of the cover 23 and the partition wall 233 is an opening through which air flows from the outside of the blower 1 to the inside of the casing 20. That is, in the first embodiment, the downstream air flow by the fan 11 and the upstream air flow flowing from the outside of the apparatus are separated by the partition wall 233. Thereby, since interference between the air flow flowing from the outside of the apparatus and the air flow in the downstream direction by the fan 11 is reduced, the air flow by the fan 11 is weakened or the straightness in the air blowing direction is reduced. It is avoided.

  4 is a schematic cross-sectional view taken along line IIII-IIII in FIG. The bottom 140 includes a lighting device 40 having a plurality of light emitting elements (LEDs) 40a, 40b, and 40c, a control unit 41 that controls signals obtained by the operation unit 101, and a power plug 42 that takes in power from an external power source. And a storage battery 43 that stores the electric power taken in by the power plug 42. The illumination device 40 is closed with a transparent window material. A partially transparent or translucent material may be used. The storage battery 43 is a battery in which 10 nickel metal hydride batteries each having a voltage of 1.2 V are connected in series. A lithium ion battery may be used.

  The storage battery 43 including a metal material such as a nickel metal hydride battery or a lithium ion battery is heavier than other materials of the blower 1. Further, in order to increase the battery capacity of the storage battery 43, it is necessary to increase the capacity of the material that chemically reacts, so the volume is inevitably increased. Therefore, in the vertically long blower device 1 according to the first embodiment, the storage battery 43 is accommodated in the bottom portion 140. Thereby, the upright attitude | position of the air blower 1 is stabilized and it is hard to fall down. Moreover, even if the volume of the bottom part 140 becomes large, it does not affect the air blowing function of the air blower 1. Furthermore, by accommodating the illuminating device 40, the control unit 41, the power plug 42, and the like in the internal space at the bottom, it becomes possible to utilize the empty space.

  By housing the illuminating device 40 in the space in the lower front part of the bottom portion 140 of the blower 1, the illuminator 40 illuminates the periphery of the blower 1 and the floor as a footlight. Thereby, since the step of the air blower 1 can be confirmed even in a dark place outdoors, it is possible to prevent a danger that the user touches the air blower 1 and falls.

  FIG. 5 is a block diagram showing the configuration of the control system of the blower according to the first embodiment. The pedestal part 141 of the blower 1 includes the operation unit 101 of FIG. In addition, the blower 1 includes a remote control signal receiving unit 103 that receives a signal obtained from a remote controller (hereinafter referred to as a remote controller) 102 in FIG. When a button on the remote control 102 is pressed, the remote control signal receiving unit 103 receives a signal by infrared rays or the like and transmits it to the control unit 41. The control unit 41 decodes the transmitted signal.

  The operation unit 101 and the remote controller 102 are respectively provided with operation buttons 301 and 321 for switching operation start and stop of the blower 1, ion operation buttons 302 and 322 for switching operation start and stop of the ion generator 213, and the blower 1. Timer buttons 303 and 323 for stopping the operation after a specified time, rhythm wind buttons 304 and 324 for changing the air volume of the blower 1 every predetermined time, weak buttons 305 and 325 for changing the air volume of the blower 1 and strong Buttons 306 and 326, left and right swing buttons 307 and 327 for swinging the wind direction of the blower device 1 left and right, vertical swing buttons 308 and 328 for swinging the wind direction of the blower device 1 up and down, and an illumination device provided at the bottom 140 40, lighting mode to illuminate the periphery of the main unit and other states (lights off or storage battery Depending on the third battery level comprises a lighting button 309,329 to switch to the battery remaining amount display mode) emission state changes, the. Here, the illumination mode is a mode in which the illumination device 40 has an amount of light that illuminates the periphery of the main body of the blower device 1, not the amount of light that allows the light emitting elements to blink or light.

  When the operation buttons 301 and 321 are pressed while the air blower 1 is stopped, the air blower 1 enters an operating state. When pressed again, the blower 1 is stopped. The following button operations indicate operations when the blower 1 is in an operating state.

  When the ion operation buttons 302 and 322 are pressed while the ion generator 213 is stopped, the ion generator 213 is operated. When pressed again, the ion generator 213 is stopped. If the timer buttons 303 and 323 are pressed when the blower 1 is in the timer-off state, the timer mode is set and “1” on the timer display unit 310 is lit. The timer display part 310 shows time until the air blower 1 is stopped. When the timer buttons 303 and 323 are pressed a plurality of times, the lighting of the timer display section 310 changes from “2” → “4” → “6”. When pressed further, the timer is turned off. When the blower device 1 is in a rhythm-like state, when the rhythm-like buttons 304 and 324 are pressed, the sending device 1 enters the rhythm-like mode. When the rhythm wind mode is set, the rotational speed of the fan motor 12 changes every fixed time, so that the air flow intensity is switched. Press again to return to the rhythmic state. When the air volume of the blower 1 is strong, pressing the weak buttons 306 and 326 weakens the volume of air blown from the blower 1. Even if the airflow is pressed again in a weak state, the airflow does not change. Similarly, when the air volume of the air blower 1 is weak, when the strong buttons 307 and 327 are pressed, the air volume blown from the air blower 1 is increased. Even if the airflow is pressed again in a strong state, the airflow does not change. When the blower 1 is not in the left / right swing state, pressing the left / right swing buttons 307, 327 causes the left / right swing mode. In the left and right swing mode, the casing 20 of the blower 1 swings left and right as the motor 145 operates. When pressed again, the left and right swing motor 145 stops. Similarly, when the vertical swing buttons 308 and 328 are pressed, the vertical swing mode is set. In the vertical swing mode, the casing 20 of the blower 1 swings up and down as the motor 31 operates. When pressed again, the vertical swing motor 31 stops.

  The above button operation is based on the premise that the blower 1 is in an operating state, but the lighting device 40 does not affect the operating state of the blower 1. For example, even when the operation buttons 301 and 321 are pressed when the lighting device 40 is lit while the blower 1 is in an operating state, the lighting device 40 remains in the lit state. By making the control of the air blowing function and the lighting function of the air blowing device 1 independent, the convenience for the user is improved.

  The illumination device 40 enters the illumination mode when the illumination buttons 309 and 329 are pressed in the unlit state. In the illumination mode according to the first embodiment, all the light emitting elements 40a, 40b, and 40c are turned on. When pressed again, the illumination mode is canceled and the light emitting elements 40a, 40b, and 40c are turned off. The luminance of the light emitting elements 40a, 40b, and 40c may be changed by the number of times the illumination buttons 309 and 329 are pressed.

  Here, if the power plug 42 is inserted into the external power supply in the illumination mode, all the light emitting elements 40a, 40b, and 40c are turned on with the maximum luminance. On the other hand, in the illumination mode, when the power plug 42 is not inserted into the external power source and is operated only by the storage battery 43, the light emitting elements 40a, 40b, and 40c may be lit while suppressing the luminance. You may reduce the number of the light emitting elements to light. Thereby, it becomes possible to suppress consumption of the battery remaining amount of the storage battery 43. In addition, you may provide the electric power supply part which can supply electric power from the outside, such as USB, instead of a power plug.

FIG. 8 is an example diagram showing the relationship between the usage time and the output voltage when the air blower according to Embodiment 1 operates with only a storage battery. At time _ta0 , the storage battery 43 is in a fully charged state.

The control unit 41 includes a voltage monitoring circuit 41 a that monitors the voltage across the storage battery 43 and detects the output voltage. The voltage monitoring circuit 41a according to the first embodiment periodically detects the output voltage. The storage battery 43 outputs 14.5 V when fully charged, but the output voltage decreases with time. A stable output of 12V is obtained from time t _a1 to time t _a2 , but thereafter, the output voltage decreases again from time t _a2 . When the voltage monitoring circuit 41a detects that the output voltage is 10.8 V at time _ta3 , the control unit 41 forcibly stops the blower 1. In time t _a2 to time after the example output voltage becomes less than 12V, the light-emitting element 40a, 40b, by lighting or flashing 40c, may indicate to the user that is only The remaining battery capacity.

  FIG. 9 is an example diagram showing a relationship between the chargeable time of the storage battery according to the first embodiment and the outputtable voltage, and FIG. 10 is a diagram of the remaining battery display mode with respect to the remaining battery capacity of the storage battery according to the first embodiment. It is an example figure.

When the output voltage of the storage battery 43 is reduced to 10.8 V, the time when the charging is started by inserting the power plug 42 of the blower 1 into the external power source is defined as t _b0 . When charging is started, the lighting device 40 is switched to a battery remaining amount display mode corresponding to the remaining amount of the storage battery 43. When the output possible voltage detected by the voltage monitoring circuit 41a is V1 (10.8 to 11.5V), the light emitting element 40a is blinked and the light emitting elements 40b and 40c are turned off. When the detected output possible voltage is V2 (11.5 to 12.0 V), the light emitting element 40a is turned on and the light emitting elements 40b and 40c are turned off. When the detected output possible voltage is V3 (12.0 to 13.0 V), the light emitting elements 40a and 40b are turned on and the light emitting element 40c is turned off. When the detected output possible voltage is V4 (13.0 to 14.5 V), the light emitting elements 40a, 40b, and 40c are turned on. When the detected output possible voltage becomes V5 (14.5 V˜), it is regarded as full charge, and charging is stopped, and the light emitting elements 40a, 40b, and 40c are turned off. Thus, in the illuminating device 40 provided as illumination, the plurality of light emitting elements 40a, 40b, and 40c are arranged in a row, and the number of lighting according to the battery remaining amount or the light emitting method such as blinking is changed to change the storage battery 43. The operating time can be represented in a pseudo manner by the remaining battery level. Thereby, it is not necessary to provide a new display unit in order to visually recognize the remaining battery level of the storage battery 43, and the user can easily visually recognize the remaining battery level of the storage battery 43. In addition, you may arrange the some light emitting element 40a, 40b, 40c vertically or diagonally. The luminance of the light emitting element may be changed. The light emitting color of each light emitting element may be changed, or a plurality of light emitting elements having different light emitting colors may be used to switch the light emitting elements to be lit.

  Here, if the output possible voltage is 18V or more, which is an overcharged state, there is a risk of heat generation, so it is desirable to lower the charge end voltage setting below the maximum output possible voltage.

  When the illumination device 40 is in the battery remaining amount display mode, when the illumination buttons 309 and 329 are pressed, the illumination mode is switched to the illumination mode. Press again to switch to battery level display mode. Thereby, when a user needs a lamp | ramp, it can switch immediately.

  Moreover, the air blower 1 is provided with the time measuring device 104 which can measure the time slot | zone during the daytime. When the lighting device 40 is in the battery remaining amount display mode, when it is determined that the time zone measured by the time measuring device 104 is nighttime, the luminance of the light emitting elements 40a, 40b, and 40c is lowered compared to the other time zones. The night time zone is, for example, from midnight to 7:00 am. Thereby, not only can the consumption of the battery remaining amount of the storage battery 43 be suppressed, but also the disturbance of sleep due to glare can be suppressed even if the user places a blower near the sleeping place. Note that the luminance of the light emitting elements 40a, 40b, and 40c may be lowered when the timing device 104 determines that it is a night time zone in the illumination mode.

Note that the light emitting elements 40a, 40b, and 40c according to the first embodiment and the embodiments that will be described later are not limited in light emission color. The light emitting elements 40a, 40b, and 40c may all have the same light emission color, or the remaining battery power may be represented by using RGB LEDs and making the light emission colors variable. Further, the number of the light emitting elements 40a, 40b, and 40c according to the present embodiment is three, but the number is not limited.
[Embodiment 2]
FIG. 11 is an example of a battery remaining amount display mode with respect to the battery remaining amount of the storage battery according to the second embodiment. The battery remaining amount display mode of the illumination device 40 according to the second embodiment is switched based on the charging time T corresponding to the output possible voltage at the start of charging.

For example, when the power plug 42 of the blower 1 is inserted into an external power supply, the voltage monitoring circuit 41a once detects a voltage that can be output. If the sensed output voltage capable were V1 (10.8~11.5V), from that point until the time _{T 1} is passed to the battery remaining display mode corresponding to the time _{T 1} of the Figure 11. After the time T _1, the voltage monitoring circuit 41a, detecting the possible output voltage once. If the sensed output enable voltage V2 (11.5~12.0V), from that point until the time _{T 2} has elapsed, the battery remaining amount display mode corresponding to the time _{T 2} of the Figure 11. However, when the detected output possible voltage is still V1 (10.8 to 11.5 V), the voltage monitoring circuit 41a is periodically monitored until the output possible voltage becomes V2 (11.5 to 12.0 V). Make it work. If the available output voltage detected by the voltage monitoring circuit 41a to V2 (11.5~12.0V), to stop the periodic monitoring of the voltage monitoring circuit 41a, until the elapse of the time _{T 2} from the time point of FIG. 11 to the remaining battery level display mode corresponding to the time T _2. After the time T _2, the voltage monitoring circuit 41a, detecting the possible output voltage once. If the sensed output enable voltage V3 (12.0~13.0V), until time elapses _{T 3} from that point, to the battery remaining amount display mode corresponding to the time _{T 3} in FIG. 11. However, if the detected output possible voltage is still V2 (11.5 to 12.0 V), the voltage monitoring circuit 41a is periodically monitored until the output possible voltage becomes V3 (12.0 to 13.0 V). Make it work. If available output voltage detected by the voltage monitoring circuit 41a is the V3 (12.0~13.0V), to stop the periodic monitoring of the voltage monitoring circuit 41a, until the elapse of the time _{T 3} from that point, in FIG. 11 to the remaining battery level display mode in accordance with the time T _3. After a time T _3, the voltage monitoring circuit 41a, detecting the possible output voltage once. If the sensed output enable voltage V4 (13.0~14.5V), from that point until the time _{T 4} has elapsed, the battery remaining amount display mode corresponding to the time _{T 4} in FIG. 11. However, when the detected output possible voltage is still V3 (12.0 to 13.0 V), the voltage monitoring circuit 41a is periodically monitored until the output possible voltage becomes V4 (13.0 to 14.5 V). Make it work. If available output voltage detected by the voltage monitoring circuit 41a is to V4 (13.0~14.5V), to stop the periodic monitoring of the voltage monitoring circuit 41a, to the time from that point _{T 4} has elapsed, in FIG. 11 to the remaining battery level display mode corresponding to the time T _4. Finally, after the time T _4, the voltage monitoring circuit 41a detects the output voltage capable once. If the sensed output enable voltage V5 (14.5V~), to the battery remaining amount display mode (off) corresponding to the time _{T 5} in FIG. 11 at that time. However, when the detected output possible voltage is still V4 (13.0 to 14.5 V), the periodic monitoring of the voltage monitoring circuit 41a is operated until the output possible voltage becomes V5 (14.5 V to). If available output voltage detected by the voltage monitoring circuit 41a is the V5 (14.5V~), to stop the periodic monitoring of the voltage monitoring circuit 41a, the battery remaining amount display mode corresponding to the time T ₅ in FIG. 11 at that time Set to (off).

  According to the processing according to the second embodiment, it is not necessary to regularly monitor the voltage of the storage battery 43. Therefore, the processing amount of the control unit can be reduced.

Incidentally, in consideration of avoidance of over-charge state, after the time T _3, until time T ₄ has elapsed, it is better to operate the periodic monitoring of the voltage monitoring circuit 41a.
[Embodiment 3]
FIG. 12 is an example diagram showing a battery remaining amount display mode and an illumination mode with respect to the output possible voltage of the storage battery according to the third embodiment. Although the battery remaining amount display mode and the illumination mode according to the third embodiment have different luminance values of the light emitting elements, the user can visually recognize the remaining amount of the battery, so that convenience is improved.

  It is assumed that the light emitting elements 40a, 40b, and 40c according to the third embodiment can shift the luminance values to 0, 1, 2, and 3. The numbers in white circles and black circles indicating the light emitting elements 40a, 40b, and 40c in FIG. 12 are set luminance values. The luminance value 0 is in the off state, and the luminance value 3 is in the on or blinking state with the maximum luminance.

  When the outputtable voltage is V1 to V4, the remaining battery level display mode and the illumination mode are different only in the luminance values of the light emitting elements 40a, 40b, and 40c. Therefore, when the illumination buttons 309 and 329 are pressed, the setting is easy because only the luminance value of each light emitting element is switched.

  When the output possible voltage is V5, the battery remaining amount display mode indicates that the charging state is completed by turning off the light. On the other hand, since the illumination mode returns to the normal illumination function state, the light emitting elements 40a, 40b, and 40c are kept on. However, the lighting of the light emitting elements 40a, 40b, and 40c is the same when the outputtable voltage is V4. Therefore, in order to make a difference between the lighting state when the outputable voltage is V4 and the lighting state when the outputable voltage is V5, the luminance value of the light emitting elements 40a, 40b, and 40c when the outputable voltage is V4 is set to 2, When the outputtable voltage is V5, the luminance value of the light emitting elements 40a, 40b, and 40c is set to 3 (maximum luminance). Here, in order to express the difference in display mode, the number of light emitting elements may be added or the number of states in the battery remaining amount display mode may be reduced. However, adding a light emitting element is not preferable from the viewpoint of cost reduction. Further, if the number of states in the battery remaining amount display mode is reduced, there is a problem that the accuracy of pseudo display of the remaining battery amount is lowered. That is, these problems can be solved by performing the difference in display mode by the displacement of the luminance value.

  All of the light emitting elements in the lighting / flashing state in the battery remaining amount display mode have a luminance value of 1. In the battery remaining amount display mode, the user need only be able to visually recognize the remaining battery amount of the storage battery. Therefore, there is no problem even if the luminance is lowered during charging, and thus power saving can be achieved.

  In the third embodiment, the remaining battery level can be visually recognized even in the illumination mode. However, after all the light emitting elements 40a, 40b, and 40c are lit at the maximum luminance as in the first embodiment, The brightness may be reduced only in the battery remaining amount display mode. Thus, as in the third embodiment, the luminance can be lowered during charging, so that power saving can be achieved.

  All the above-described embodiments are examples in all respects, and should be considered not restrictive. The scope of the present invention is not intended to include the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.

  In addition, as long as the effect of the present invention is obtained, the blower 1 may include components that are not disclosed in the embodiment.
