Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating air blower that can swing up and down, and particularly to an oscillating air blower that is attached to a wall and used for drying and cooling hair and the body.

0002

BACKGROUND OF THE INVENTION In a blower device used for this purpose, a louver is used as a means for changing the blowing direction up or down, which is arranged at the blower opening and can be changed manually or electrically.

0003

[Problems to be Solved by the Invention] In this case, even if the wind direction can be changed continuously up and down by moving the louver electrically, the range of angles that can be changed is narrow, which often causes dissatisfaction in practical use. The present invention has been made in view of these points, and its purpose is to provide an oscillating blower device that is easy to use.

0004

[Means for Solving the Problems] The present invention provides a blower unit having a blower means and a heating means and whose lower end serves as a blower port, and an electric motor that swings the blower unit vertically. It is equipped with a swinging mechanism, the swinging angle of which is approximately 20° to approximately 70° with respect to the vertical direction.
It is characterized by an angle range of .

According to the present invention, the head is automatically oscillated over a wide range of vertical directions.

[0006]

[Embodiment] The present invention will be described in detail below based on the illustrated embodiment.A ventilation unit A is disposed at the top of a vertically elongated vessel body 12, and an operation panel 13 is disposed at the center of the vessel body 12. A far-infrared ray emitting section 9 is provided below the operation panel 13, and a warm air outlet 14 is formed at the lower end of the vessel 12 from which warm air passing through the vessel 12 is blown from the blower unit A. .

The blower unit A here has a blower means and a heating means built into a housing 4 which has a blower port 3 on its lower end surface, and the upper part of the container body 12 is vertically movable. The swing mechanism 8 is attached to the housing 4 and can swing up and down by a swing mechanism 8 built into the housing 4. As shown in FIG. A shaft 40 fixed via
A gear 6 is fixed to the shaft 40, a geared motor 9 is fixed to the housing 4, and a pinion 10 is attached to the output shaft of the geared motor 9 and meshes with the gear 6. Bearing 7 for 40
When the pinion 10 is rotated by the geared motor 9, the blower unit A swings up and down as shown in FIG. Further, as shown in FIGS. 1 and 5, the blower unit A here is biased in the upward movement direction by a tension coil spring 11, so that the load applied to the geared motor 9 is reduced.

A rotation angle detection plate 1 is mounted on the shaft 40.
7 is fixed, and a slit 17a shown in FIG. 8 is formed in the rotation angle detection plate 17 on the housing 4 side.
, 17b is attached, so that it is possible to detect the state in which the blower unit A makes an angle α with respect to the vertical direction, and the state in which it makes an angle β with respect to the vertical direction. Note that here, the angle α is 20° and the angle β is 70°. Further, the geared motor 9 is such that when the blower unit A is within the above-mentioned angle range, the rotation direction is switched by a forward/reverse switch SW each time the photo sensor 18 detects the slits 17a, 17b, as shown in FIG. Therefore, the vertical swinging motion of the blower unit A is within the above angle range (20° to 70°).
repeated within.

As shown in FIG. 6, if the average height of the user is 1 m 60 cm, the operation panel 13 has a height of 1 m 30 cm.
It is easy to use when the height is about 1 m, and taking this into consideration, the upper end of the fan unit A will be at a height of about 1 m 80 cm.
When used at a distance of approximately 0 cm, if the head is swung within the above angle range, the wind can be applied from approximately the top of the head to the height of the knees. The areas that will be desired to be dried and cooled will be completely covered.

FIGS. 9 and 10 show another embodiment. This allows the user to swing within the desired angle range, so if the user sets the upper and lower limits of the swing rotation in advance, the swing will be performed within this range. A large number of slits 17c are formed in the rotation angle detection plate 17, so that a large number of angles can be detected. When the user sets the upper and lower limits using the switches on the operation panel 13, these values are stored in the memory circuit M, and by comparison with the current angle of the blower unit A, the stored upper and lower limit angles are reached. The geared motor 9 reverses each time. In this case, turn the hair drying mode switch on the operation panel 13.
If this hair drying mode switch is turned on, the lower and upper limits are set to values of angles between 60° and 70° with respect to the vertical line, and hair drying can be performed quickly. Can be done.

FIG. 11 shows a case where the swinging motion is disturbed by something. The operation interval of the forward/reverse changeover switch SW is measured by a timer T, and when this time exceeds a set value, the geared motor 9 is forcibly stopped via the drive switch S. It is desirable to measure the time required to return the air blower unit A to the storage state in which the air outlet 3 faces straight down, and to turn off the drive switch S if this time becomes longer than a predetermined value.

FIG. 12 shows the far-infrared radiation section 9. As shown in FIG. In the figure, 31 is a protective net, 32 is a quartz tube heater that emits far-infrared rays, and above this far-infrared rays radiating section 9 is a human body detection sensor 33 and a display indicating whether to enable or disable this human body detection sensor 33. A switch 34 for switching is provided. Now, if you turn on this switch 34 to enable the human body detection sensor 33, the human body detection sensor 33 will detect it just by standing in front of it without turning on the switch on the operation panel 13, as shown in FIG. Since the quartz tube heater 32 is energized via the electronic switch SS, the effort of operation is not required during the winter season.

If an ultrasonic Doppler type sensor, that is, a type that detects movement, is used as the human body detection sensor 33, no malfunction will occur even if an object is placed within the detection area. Of course, by providing an off-delay circuit for several tens of seconds until the device is turned off once it is turned on, the device can be used without any problem even if the user stands still in front of the device.

[0014]

[Effects of the Invention] As described above, in the present invention, since the swinging motion angle ranges from about 20° to about 70° with respect to the vertical direction, the wind can be directed almost from the top of the head to the knees. It is very easy to use because it can be moved vertically over a wide range automatically.
