Description

[Detailed description of the invention] This invention relates to a wall dryer.

Traditionally, hot air generators (hair dryers) that can switch between hot and cold air have been installed on walls and used for washing and drying hair and for heating indoor rooms, but since washrooms are often located next to bathrooms, they are not suitable for summer use. However, there was a drawback that the washroom was inevitably hot and humid, requiring ventilation when washing and drying hair.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wall-mounted dryer that can be used for multiple purposes such as heating, ventilation, and hair drying, and is also energy efficient and easy to use.

An embodiment of the invention is shown in FIGS. 1 to 4. That is, in this wall dryer, a dryer main body 1 having a housing made of plastic or metal is rotatably held by a fixed base 2, and the fixed base 2 is placed near a ventilation wall opening 4 formed in a wall 3 or window frame. The ventilation port 5 and the opening 4 on the back side of the dryer main body 1 are connected by a telescopic intake and exhaust pipe 6 formed of a bellows. The fixed base 2 is provided with a main switch 7 and a suction/exhaust changeover switch 8, and is attached to the wall 3 by passing a mounting screw 10 through a mounting hole 9. Furthermore, fixed stand 2
As shown in FIG. 3, a pivot hole 12 is formed in the arm 11 provided on both sides of the upper end, and a recess 13 is formed inside the pivot hole 12.
The support shaft 15 of the dryer main body 1 is
is passed through the pivot hole 12 via the disc spring 14 and tightened with the knob handle 16, so that rotation of the dryer main body 1 is fixed by the spring friction of the disc spring 14. The dryer main body 1 has a grid 18 on the front side ventilation port 17, a forward and reverse rotation motor 9 is arranged inside, and a fan 20 is connected to the motor shaft.
Furthermore, a heater 21 is disposed between the fan 20 and the grid 18.

FIG. 4 is a control wiring diagram of this wall-mounted dryer.

P is the plug, S is the contact of the main switch 7.

H is a temperature heater for equipment protection, Th is also a thermoswitch, Q is a heater wire of the heater 21, BD is a rectifier bridge consisting of a diode D, S3 is a contact of the suction/exhaust switch 8, D is a diode, and Ry is a relay. , r is a normally open contact provided to the relay, 1M is the rotor of the motor 9, and N and S are its magnets.

This wall-mounted dryer has three functions: hair drying, heating, and ventilation.
There are two actions. That is, in the first hair drying operation, the contact S3 of the suction/discharge changeover switch 8 is switched to the position a side, and the contact S of the main switch 7 is turned on (assuming that the plug P is inserted into the outlet).

As a result, the alternating current is rectified by the rectifying bridge BD, and the pole L□ becomes the positive side and the pole L2 becomes the negative side.

A unidirectional current is applied to relay R and motor 19. The relay Ry closes the relay contact r, and the motor 19 rotates the fan 20 in one direction, sucking air from the outdoor X through the entire opening 4 into the dryer main body 1 through the lattice 18 and into the indoor Y in FIG. Blow out. Therefore, if the washed head is placed in front of the grating 18, cold air drying will be performed, but it will be more effective if the knob handle 16 is loosened and the dryer body 1 is rotated so that the grating 18 is directed toward the head. Note that due to the rotation of the dryer body 1, the intake and exhaust pipes 6
follows as shown in Figure 2. In addition, when drying with hot air, if contact S of main switch 7 is turned on in that state, relay contact R is closed.

The heater 21 generates heat, and the air blown out becomes warm air. Cold air can also be generated by switching contact S2 on and off.

Warm air can be switched arbitrarily. Next is the case of indoor heating. The operation in this case is the same as in the case of hot air drying. In this case as well, the blowing direction can be arbitrarily determined by loosening the knob handle 16. Finally, the ventilation operation is the same as the cold air drying described above when air is taken into the room, but in the case of outdoor exhaust, the contact S3 of the intake/exhaust selector switch 8 is switched to the position, and the contact S1 of the main switch 7 is turned on. Then.

Since the rectifier diode BD has a positive polarity and a direction opposite to that of the diode D, no current flows through the relay, and the motor 19 rotates in the opposite direction.

Therefore, the fan 20 rotates in the opposite direction, and the air from indoors Y is transferred to outdoor X.
is exhausted. Since the relay contact r is open at this time, even if the contact S2 is turned on by mistake, the heater 21 is not energized, the heater 21 does not generate heat, and there is no waste of power consumption.

As described above, in the wall dryer of the present invention, the main body of the dryer having a forward and reverse rotating fan is attached to the wall opening, and the heater is turned off when exhausting the air outdoors. Ventilation is achieved through outdoor exhaust, and the heater is turned off during ventilation (5), ensuring energy savings.
Easy to use. As an embodiment, if the heater can be turned on and off freely when blowing air indoors, both hot air and cold air can be obtained, and the hair dryer can effectively set the hair. In addition, if the main body is made adjustable in direction and angle, and is connected to the wall opening with a telescopic intake and exhaust pipe, the air discharge angle can be adjusted, making it easy to use.
