By the way, the boss 22 of the switch cover 11
A packing plate 24 made of rubber or the like is arranged on the outside of the switch cover 11 so as to close the outside of the switch cover 11.

A switch box 25 is fixed to the outside of the packing plate 24.

A fixed contact 26 and a movable contact 27 are provided within the switch box 25. The movable contact 27 is provided on the free end side of the leaf spring 28 whose one end is fixed in the switchbox 25, and the movable contact 27
is facing.

Further, one end of a lever 29 is fixed to a pair with the leaf spring 28, and the tip of the lever 29 faces the shaft 20b of the switch button 20 on the outside of the packing plate 24.

By the way, the end of the cord 3 on the storage stand 2 side passes through the lower part of the storage stand, passes through the side of the switchbox 25, and is connected to the fixed contact 26 side via the plug 30 at the upper end of the switchbox 25. ing.

By the way, a triangular opening 31 is formed on the back surface of the recess 7 of the storage table 2. This opening 3
1 is for fixing the storage stand to the wall side, and the storage stand 2 is attached to the wall side via the mounting plate 32 shown in FIG.
is installed.

As shown in FIG. 5, the mounting plate 2 is formed into a quadrilateral shape as a whole, and is screwed to a wall surface etc. through through holes 32a formed above and below.

A triangular protrusion 33 is provided on the outer side of the mounting plate 32 .

This triangular protrusion 33 has protrusions 33a and 33b that protrude slightly on its upper and lower peripheral edges,
The size of the triangle including these protrusions 33a and 33b is approximately the same size as the opening 31.

Further, the distance between the protrusions 33a, 33b and the outer surface of the mounting plate 32 is approximately the same as the thickness of the back surface of the recess 7.

Furthermore, a protrusion 34 is provided below the triangular protrusion 33 at a predetermined distance and extends parallel to the lower side of the protrusion 33 over a predetermined length.

Furthermore, a U-shaped protrusion 35 that opens downward is provided on the back side of the upper end of the protrusion 33 .

The distance between the protrusion 35 and the protrusion 34 is equal to the length of the opening 31 of the storage table 2 in the vertical direction.

Therefore, the mounting plate 32 is screwed and fixed to the wall surface, the opening of the recess 7 of the storage stand 2 is brought close to the protrusion 33, the protrusion 33 is fitted into the opening 31, and the upper and lower protrusions 33a and 33b are attached. The peripheral edge of the opening 31 of the recess 7 is fitted between the outer surface of the plate 32 and the outer surface of the plate 32 so as to be narrowed.

Next, the storage table 2 is pulled down, the protrusion 33 is moved above the opening 31, the protrusion 35 is brought into contact with the upper end of the opening 31, and the protrusion 34 is engaged with the lower edge of the opening 31. The base 2 is completely fixed to the mounting plate 32 and will not come off.

Next, a method of using the hair dryer according to the present invention constructed as above will be explained.

Power cord 3 led out from the mounting base 2 side
When the plug 37 of No. 6 is inserted into the outlet, the current is supplied to the fixed terminal 26 side.

When the dryer body 1 is fitted into the storage stand 2 in this state, the protrusion 5 on the dryer body 1 side is fitted into the recess 7, and the grip portion 4 comes into contact with the front surface of the protrusion 8, as shown in FIG. The dryer main body 1 is completely fitted into the storage stand 2 as shown in FIG.

In this state, the heads 9 of the slide levers 9 and 10
d and 10d are pushed downward by the lower edge of the bulge 5 and are fitted into the recess 5a formed in the lower edge of the bulge 5.

Even when the two slide levers 9 and 10 are lowered, the cam portions 19c and 20c of the reset button 19 and the switch button 20 remain in the large quadrilateral openings formed by the notches 9b and 10b and 9a and 10a of the slide levers 9 and 10. Since the cam parts 19c and 20c are fitted inside, no force is applied to the cam parts 19c and 20c, and the two buttons 19 and 20 are not operated by the slide levers 9 and 10, and the movable contact 27 and the fixed contact 26 is not in contact and the switch is in the off state.

On the other hand, when the slide levers 9 and 10 are lowered, the protrusion 13a of each lever is moved to the release lever 1.
4, the release levers 14, 14 are once attracted to the slide lever side, but when the heads 9d, 10d fit into the recess 5a, the force of the spring 12 forces the slide lever 9. ，
10 moves upward and the protrusion 13a moves upward in the elongated hole 17, so that the release levers 14, 14 are in a state of protruding outward again.

On the other hand, when the dryer main body 1 is fitted onto the storage stand 2 side, the grip section 4 presses the reset button 19 protruding from the front surface of the protrusion section 8. At this time, as described above, the two slide levers 9, 1 are pressed.
0 is descending, and the cam portion 19c is in the notch portions 9b, 1
The cam portion 19c and the slide levers 9, 10 do not engage with each other only by fitting into the large opening formed by the cam portion 0b.

In this state, the dryer main body 1 is completely fitted to the storage stand 2 side, and the heads 9d and 10d of the two slide levers are fitted into the recess 5a on the lower edge of the bulge 5 of the main body. Therefore, the dryer main body 1 is locked and cannot be taken out.

If you want to take out the dryer main body 1, open your palms and press the left and right release levers 14, 14 at the same time.

Then, the protrusions 13a of the slide levers 9, 10
are fitted into the elongated holes 17, respectively, so that the protrusions 13a are pushed downward, and the slide levers 9 and 10 are lowered.

As a result, the cam portion 19c was engaged with the lower edge of the quadrilateral opening formed by the notches 9b and 10b.
is disengaged and the reset button 19 is pushed out by the force of the spring 21.

At this time, the heads 9d of the two slide levers,
10d has been lowered and is out of the recess 5a on the lower edge of the bulge 5, so the protrusion of the reset button 19 pushes the dryer main body 1 forward, making it difficult for the user to grasp.

Only in this state can the user take out the dryer main body 1.

By the way, since the release levers 14 and 14 are set at a width that is impossible for a child's hands to press simultaneously, it is impossible for a child to take them out.

If the child wants to take it out, he or she must use both hands at the same time, and must press the release levers 14, 14 with both hands at the same time.

If only one of the release levers is pressed, only the slide lever on the side corresponding to that release lever will be lowered, the other slide lever will not be lowered, and the cam portion 19c of the reset button 19 will be pushed down by the notches 9b and 10b. The reset button 19 is hooked to the lower edge of either side, so that the reset button 19 does not protrude and the dryer main body 1 is not pushed out.

By the way, even if the dryer main body 1 is simply removed, no current is supplied to the main body side.

Therefore, even if the main body 1 of the dryer is accidentally dropped into water in a bathtub or washbasin, an electric shock will not occur.

To operate the dryer main body 1, the switch button 20 can be pressed after removing the main body.

Then, the slope 20d of the cam portion 20c of the switch button 20 aligns with the notches 9a, 10 of the slide lever.
In order to press the lower edge of the quadrilateral opening formed by a, the slide levers 9 and 10 descend against the elastic force of the spring 12, and the cam portion 20c moves into the notch portions 9a and 1.
Go over the lower edge of 0a.

Then, the slide levers 9 and 10 rise due to the force of the spring 12, and the cam portion 20c moves into the notch 9.
It is hooked by the lower edge of a, 10a.

When the button switch 20 is pressed, the shaft 20b moves forward and pushes the lever 29 through the packing plate 24 made of an elastic member such as rubber, so that the movable contact 27 and the fixed contact 26 come into contact, turning on the switch and turning on the code 3. An electric current is supplied to the dryer main body 1 side through.

This is the first time the dryer is in the starting state.

Since an adjustment switch 6 is provided on the side of the dryer main body 1, hair can be set while adjusting the strength of the fan's wind by operating this switch.

After the hair is set, when the dryer main body 1 is fitted onto the storage stand 2 side, the slide levers 9, 10, reset button 19, and switch button 20 return to their initial states as described above.

As is clear from the above explanation, according to the present invention, the dryer device is divided into the main body and the storage stand, and when it is stored in the storage stand, there is no clue to pull it out with your fingertips, and unless you press the release lever, the main body Since the structure is such that the parts cannot be taken out, it is possible to prevent children from playing around with the product and causing electric shock accidents.

Further, the release lever is in a position that cannot be operated by a child's palm size, and the main body cannot be removed without operating the release lever at the same time, so the main body cannot be removed and played with.

Removing the main unit in this way is itself a double safety mechanism, and even if the main unit is removed, no current is supplied to the main unit unless the switch button is pressed, so there is no possibility of accidentally dropping the main unit into a bathtub etc. It is possible to provide a dryer device equipped with a triple safety mechanism that prevents electric shock accidents even when the electric shock occurs.
