Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hair dryer used in barbering and beauty treatments.

[Conventional technology and its problems]

A heating device support arm is attached to the upper part of the pillar that stands up from the pillar support stand, and a heating device support arm is attached to the side and extends out from the side, and a heating device support is connected to the tip of the heating device support arm, and a plurality of heating device supports are arranged around the heating device support. Hair dryers that use a heater as a heat source to dry hair have long existed.

The above-mentioned hair dryer is designed so that the distance between the hair and the heater can be adjusted arbitrarily by adjusting the height of the support, and the heater is supported so that it can be lowered freely relative to the heat generating support, so that the direction of the heat source can be adjusted. However, when the hair is dry,
Since the heater is in a fixed arrangement, the heating strength differs between the heating area facing the heater and the area around it, which is disadvantageous in that the hair cannot be heated uniformly over the entire head.

[Purpose of the invention]

Therefore, the present invention solves the above-mentioned inconvenience by imparting rotational movement around the axis of the support to a heating device support that supports a plurality of heating devices such as heaters, and furthermore, An object of the present invention is to provide a hair dryer capable of uniformly heating almost the entire head of hair by giving a motion that tilts the center of rotation with respect to a vertical line while swinging a support body from side to side. It is said that

[Problem for invention]

In order to achieve the above object, in the present invention, a bracket is attached to the tip of the support shaft, the motor and the drive shaft rotated by the motor are supported by the bracket, and the lower end of the drive shaft is A heating element support is connected to the part, a plurality of heating elements are attached around the heating element support, an inclined cam is installed in the middle of the drive shaft, and a slider is brought into contact with the flank of the inclined cam. A support frame is non-rotatably connected to a support cylinder that is fitted on the outside of the support shaft and rotatably supports the support shaft, a rear end of the support frame is rotatably connected to a fixed bracket, and The deflection/oscillation cam attached to the rear end of the support shaft is provided with a cam surface inclined in the axial direction of the support shaft, and the deflection shaft in contact with the cam surface is supported by the fixed bracket.

[Effect]

In the above configuration, when the motor is driven, the heating element rotates around the axis of the drive shaft. Also,
The tilting cam rotates together with the drive shaft, and the support frame of the slider that contacts the tilting cam does not rotate with respect to the support cylinder, so that the movable bracket tilts left and right.
At this time, the support shaft rotates with respect to the support tube, so
A reaction force is biased between the cam surface of the deflection/swing cam at the rear end of the support shaft and the deflection shaft that is brought into contact with the cam surface. Due to the bias of the reaction force, the support tube that supports the support shaft swings left and right about the connecting portion to the fixed bracket. Therefore, the heating element has three types of motion: rotational movement around the drive shaft, left and right rocking movement around the joint between the support tube and fixed bracket, and tilting movement around the axis of the support shaft. Two compound movements are given.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

〔Example〕

As shown in FIGS. 1 and 2, the hair dryer according to the present invention has an L-shaped support arm 3 attached to the upper part of a telescopic column 2 rising from a column support 1. A heat generating device 10 is provided.

As shown in FIGS. 3 and 4, the heat generating device 10 includes a support shaft 11, and a movable bracket 12 for supporting a motor is attached to the tip of the support shaft 11.

A motor 13 and a drive shaft 14 rotated by the motor 13 are supported on the movable bracket 12, and a heating element support 15 is attached to the lower end of the drive shaft 14. In addition, the heating device support 1
As shown in FIGS. 1 and 2, a plurality of support arms 16 are attached to the support arm 5, and a heat generating device 17 such as a beam lamp is swingably supported at the tip of the support arm 16.

Furthermore, an inclined cam 18 is attached to the middle of the drive shaft 14, and the cam groove 1 of the inclined cam 18
A slider 20 is fitted to both flanks of the slider 20, and a U-shaped support frame 21 that supports the slider 20 is fitted to the outside of the support shaft 11 to rotatably support the support shaft 11. The sleeve 22 is connected to the distal end of the sleeve 22.

A pin 23 is provided on the upper outer periphery of the sleeve 22, and the pin 23 is fitted into a notch 25 at the tip of the support tube 24 fitted on the outside of the sleeve 22, so that the sleeve 23 is attached to the support tube 24. It is prevented from rotating.

The support tube 24 has a pair of protrusions 2 on the top and bottom of the rear end.
6 and 26, and the projecting piece 26 is rotatably connected to a pair of supporting pieces 28 formed on a fixed bracket 27 via a pin 29.

Note that the fixed bracket 27 is connected to the support arm 3 via a connector 30.

A deflection/swinging cam 31 is attached to the rear end of the support shaft 11, and a cam surface 32 inclined in the axial direction of the support shaft is formed on the cam 31. A deflection shaft 33 is in contact with the cam surface 31. is arranged on a horizontal plane including the axis of the support shaft 11, and both ends are supported by the fixed bracket 27.

The hair dryer shown in the embodiment has the above-mentioned structure, and this hair dryer aligns the center of the heating device support 15 with the center line of the head of a barber or beautician who is sitting on a chair for hairdressing or cosmetology. The drying process is performed.

Now, when the motor 13 shown in FIG. Rotate around the center.

Further, as the drive shaft 14 rotates, the inclined cam 18 rotates together with the drive shaft 14.
The support frame 21 of the slider 20 that fits into the cam groove 19 of
Since the tilt cam 18 is configured to be prevented from rotating relative to the support tube 24, the inclined cam 18 rotates along the slider 20. Therefore, the cam 18, the drive shaft 14 that supports the cam 18, and the movable block 12 that supports the drive shaft 14 are tilted left and right about the axis of the support shaft 11 as shown in FIG. The tilting of the bracket 12 causes the support shaft 11 to rotate by a predetermined angle. As the support shaft 11 rotates, the deflection/tilting cam 31 also rotates, and the cam surface 32 of the cam 31 and the deflection shaft 33 in contact with the cam surface 32 of the cam 31 rotate.
A biased reaction force occurs between them. At this time, since the deflection shaft 33 is in a fixed arrangement, the cam 3
1 tries to rotate in a direction that absorbs the bias of the reaction force, and rotational deflection force acts on the support shaft 11 that supports the cam 31 and the support cylinder 24 that supports the support shaft 11. Therefore, the support tube 24 swings left and right about the pin 29, as shown in FIG.

6 to 8 are schematic diagrams showing the movement of the heat generating device 17 by driving the motor 13, FIG. 6 shows the position of the heat generating device 17 when the motor 13 is stopped, and FIG. 6 A is a plan view. And the upper and lower heating devices 1
7 faces the side of the head and hair of a beautician seated below the heating device 10, and FIG. 6B shows a front view seen from the left side of FIG. 6A.

In the state shown in FIG. 6, when the motor 13 is driven and the drive shaft 14 is rotated by 90 degrees, the support cylinder 24 swings leftward by an angle (α) about the pin 29. Further, the drive shaft 14 is tilted to the left about the axis O of the support shaft 11, and the plane X including the center of the heating element 17 is tilted by an angle β with respect to the horizontal plane Y (see (See Figure 7 B).

When the drive shaft 14 further rotates 90 degrees from the state shown in FIG. 7, the heating element 17 returns to the state shown in FIG.
When rotated 90 degrees from that point (rotated 720 degrees from the original position), the support tube 24 swings to the right at an angle α' around the pin 29, and at the same time, the drive shaft 14 tilts to the right around the axis O. do. For this reason, the heating device 17
The plane X including the center of is inclined with respect to the horizontal plane Y by an angle β' in the direction opposite to that in FIG. 7B (see FIGS. 8A and 8B).

As described above, when the motor 13 is driven, the heat generating device 17 rotates around the head of the beautician who is seated below the heating device 10, and during the rotation, the heat generating device support 15 that supports the heat generating device 17 moves around the head of the beautician who is seated below the heating device 10. As a result, almost the entire hair on the head is uniformly heated.

As described above, in this invention, a plurality of heating devices supported by a heating device support are rotated around the head hair of a barber or beautician who is seated below the heating device support. Since the heating device support that supports the heating device is given two motions: moving to the side of the head and tilting with respect to the horizontal plane, it is possible to uniformly heat almost the entire hair on the head. can.
