Description

[Detailed description of the invention] This invention relates to a hair dryer, and is a cord-wrapped type hair dryer that has a cord bush that can be folded up and down to lock the switch in the off position.
The purpose is to improve operability by preventing the switch from becoming locked due to the cord bush falling down during use.

An embodiment of this invention is shown in FIGS. 1 to 7. That is, this hair dryer has a flat main body Q, a circumferential groove 1 for winding the cord A is formed on the outer periphery, a discharge port 2 is formed in the circumferential groove 1, and the suction port 3 is approximately A motor 6 is disposed in the center of the upper plate 4 and a lower plate 5 facing each other, and a Shirotsuko fan 7 is attached to surround the motor 6, so that the air flow from the fan 7 is directed toward the discharge port. A guide 8 is formed, and a heater block 9 is disposed near the discharge port 2. Further, a switch block 10 is arranged next to the heater block 9,
The sliding operation button 11 is exposed on the upper plate 4. This operation button 11 is interlocked with an operation cam 12, and an engagement recess 13 is formed in the side of the operation cam 12. A cord bush 14 is arranged to face this engagement recess 13, and the cord bush 14 projects a shaft 16 above and below the base end 15, and bearings 17 are mounted on the upper plate 4 and lower plate 5 of the main body Q. The cord bush 14 is supported by a bearing 17 so as to be rotatable between a lying state S parallel to the circumferential groove 1 and an upright state L substantially perpendicular thereto. Then, a hook 18 is protruded from the base end portion 15 on the opposite side of the cord bush 14, and the operating cam 12 is placed in the off position a with the cord bush 14 in the laid down state S and the hook 18 in the off position a.
When the switch 10a is in the ON position b (solid line in FIG. 4), the hook 18 is supported by the operation cam 12 and the cord bush 14 is supported in an upright position. ing. Further, a protrusion 19 is formed on the lower surface of the base end 15 of the cord bush 14, and the lower plate 14 facing the protrusion 19
The cord bush 1 is formed by forming an arcuate projection 20 of
When rotating from the collapsed state to the standing state as shown in Figure 4, or when rotating in the opposite direction (Figures 5 and 6)
(Fig.), the protrusion 19 is made to ride over the arcuate protrusion 20, and its operation provides clickability, and the upright posture of the cord bush 14 is such that it does not fall easily even when the operation button 11 of the switch 10a is in the OFF position. I have to. 21 is a wire connection part.

When this hair dryer is not in use, the cord bush 14 is folded down (winding the cord in an upright position impairs portability), and the cord A is inserted into the circumferential groove of the dryer body Q.
Roll it up and carry it around for storage. In this case, since the hook 18 of the cord button 14 is locked in the engagement recess 13 of the operation cam 12, even if you accidentally try to turn the operation button 11 of the switch 10a to the on position while the cord plug is plugged into the outlet, , it is in a locked state, and the cord bush 14 cannot be operated because it is supported by the wrapped cord A. Therefore, the cord A blocking the discharge port 2 will not be burned out by the hot air. , is safe. On the other hand, when in use, the power cord A is removed from the circumferential groove 1, and the cord bush 14 is held upright by the click action of the protrusion 19 and the arc-shaped protrusion 20, so that the cord bush 14 easily falls down when the operation button 11 of the switch 10a is turned on. There is no problem with its operation. In this regard, conventionally, the 8th
As shown in the figure, since there was no means to hold the cord bush 14 upright, even if the cord bush 14 was stood up, it would easily fall down due to the weight of the cord or the cord being pulled. The added load made the operation difficult, which could lead to a misunderstanding that a malfunction had occurred.

Note that when the switch 10a is turned on, the motor 6
Power is supplied to the heater block 9, and the fan 7 rotates to take in air from the suction port 3, which passes through the heater block 9 along the wind guide 8, where it is heated and becomes hot air from the discharge port 2. Breathe out.

As mentioned above, the hair dryer of this invention is
Since the switch is locked in the OFF state when the cord bush is in the laid down state, and the cord bush is kept in the upright state so that it does not fall down easily, it has the advantage of good operability during use.
