BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air dryer installed on a wall of a toilet or the like so as to blow hot air.

[0002]

2. Description of the Related Art Conventionally, a hot air dryer for blowing hot air for drying hands has been installed on a wall surface of a toilet or the like.
Although a control circuit and the like are assembled, there is a problem that the overall shape of the hot-air dryer becomes large because such electric components are built in, and when installing and maintaining the hot-air dryer. In addition, when replacing the power supply wiring and fuses, if the terminal block and fuse are assembled on the back side, the work becomes extremely troublesome, and there are problems such as damaging the control circuit by mistake. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and enables electric components to be mounted in a small space, to protect a control circuit well, and to provide power supply wiring. The purpose of the present invention is to provide a hot-air dryer that facilitates fuse replacement. The gist of the invention is that a lower part of a base chassis to which a fan is mounted has a horizontal protrusion protruding forward, and a lower part hanging down from a front end of the horizontal protrusion. The plate is formed in a step shape, a terminal block and a fuse are assembled on the front side of the lower plate, and a control circuit is assembled behind the lower plate.

[0004]

The lower plate of the base chassis has a stepped lower plate, so that the control plate can be attached to the rear of the lower plate with good protection, and a cover is provided on the front side of the lower plate. When the terminal is removed, the terminal block and the fuse are assembled so that the power supply wiring and fuse can be easily replaced, facilitating installation and maintenance, as well as protecting the control circuit well and assembling the electric components compactly. Space can be saved and the hot air dryer can be downsized.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of a hot-air dryer. This hot-air dryer 1 is installed on a wall W of a toilet or the like. A power supply box B is formed, and a mounting bracket 3 is previously fixed to a wall surface W via screws 2 and 2 on the upper part of the power supply box B. 1 can be hung, and the power supply box B is concealed by the hot-air dryer 1 in the hung state. A power supply lead-in tube part 5 projecting forward is integrally formed at the position of the power supply box B with a resin base cover 4 constituting a rear surface portion of the hot air dryer 1. The portion 5 is formed on a tapered inner peripheral surface having a wide inside diameter of the opening on the rear surface side and a small inside diameter of the opening on the front end side.

A metal base chassis 6 is mounted on the front side of the base cover 4, and the base chassis 6 is folded into a shape having an upper plate 6a, a horizontal projecting portion 6b, and a lower plate 6c. A motor 7 and a fan 8 are attached to the front surface of an upper plate 6a of the base chassis 6 in a curved shape, and the lower plate 6c has a horizontal projection 6b.
Are formed in a stepped manner, and a gap is formed between the base cover 4 and the base cover 4.
The lower plate 6c of the base chassis and the base cover 4
The control circuit unit 9 is assembled in the gap between them. Also,
A terminal block 10 and a fuse 1 are provided on the front side of the lower plate 6c.
1 and the heater 12 are assembled.
Is covered with a protective plate 13.

Further, a human body detecting sensor 14 and a temperature sensor 15 are provided below the lower plate 6c of the base chassis, and the human body detecting sensor 14 has a hand extended to the lower part of the hot air dryer 1. When detecting this, a detection signal is transmitted to the control circuit unit 9, and the control circuit unit 9 can energize the fan 8 and the heater 12 to blow out warm air downward. The temperature sensor 15 can detect the temperature of the surface of the hand so as to blow out a suitable temperature of hot air, and can transmit the signal to the control circuit unit 9.

The end of the power supply line is previously drawn into the power supply box B by an electrician, and the hot air dryer 1
At the time of mounting, the power line is passed through the power line lead-in tube portion 5 and the end of the power line is connected to the terminal block 10. After the connection work of the power line is completed, the base cover 4 The front cover 16 is inserted into the outer periphery from the front.
The electric components such as the fan 8 and the heater 12 are covered by the front cover 16. The front cover 16 is made of metal with an emphasis on robustness. In order to ground the front cover 16, as shown in a perspective view of a main part of FIG. Along with this, a leaf spring-shaped grounding member 18 is disposed outward, and a mounting portion 17 at the inner end of the grounding member 18 is mounted to the metal base chassis 6 via a screw or the like. It has become something.

When the front cover 16 is fitted to the outside of the peripheral edge 4a of the base cover 4, the outer end of the grounding metal 18 contacts the inner peripheral surface of the front cover 16,
The grounding member 18 is sandwiched between the inner peripheral surface of the front cover 16 and the outer peripheral surface of the peripheral portion 4a of the base cover 4.
Therefore, when the front cover 16 is fitted, the metal front cover 1 is
6 and the metal base chassis 6 are electrically connected to each other, can be grounded well, and even if the user touches the front cover 16, there is no electric shock or the like.
Safety is ensured. When the front cover 16 is mounted, the grounding metal 18 is in a concealed state, so that the external shape is neat. When the front cover 16 is removed, the front cover 16 can be easily detached from the base cover 4 by removing it. The front cover 16 can be easily removed and repaired, for example, at the time of repairing electrical parts and the like, and the maintenance is excellent.

As described above, in the present embodiment, the horizontal projecting portion 6b is formed on the base chassis 6, and the horizontal projecting portion 6b is formed.
Since the lower plate 6c is integrally formed so as to hang down from the front end of the lower plate 6b, a gap is formed behind the lower plate 6c. When the terminal block 10 and the fuse 11 are assembled on the front side of the lower plate 6c and the front cover 16 is removed, these terminal blocks 1
Since the fuse 0 and the fuse 11 are exposed to the front side, the power supply line can be easily connected to the terminal block 10 from the front side through the power supply lead-in tubular portion 5, and wiring work is facilitated. Also,
The replacement of the fuse 11 during maintenance can be easily performed from the front side. Moreover, the control circuit unit 9
Is mounted behind the lower plate 6c in a space-saving manner, so that the electric parts can be mounted compactly as a whole, and the entire hot-air dryer 1 can be reduced in size.

[0011]

According to the hot air dryer of the present invention, a horizontal protruding portion protruding forward and a lower plate hanging down from the front end of the horizontal protruding portion are formed stepwise below the base chassis on which the fan is mounted. The terminal board and the fuse are assembled on the front side of the lower plate, and the control circuit is assembled on the rear side of the lower plate, so that the control circuit is arranged on the rear side of the lower plate of the base chassis. By assembling the terminal block and the fuse, these electric components can be assembled in a space-saving manner, and the entire hot-air dryer can be reduced in size. In addition, since the terminal block and the fuse are arranged on the front side, power supply wiring at the time of construction is easy, and replacement of the fuse is also easy. Further, since the control circuit is disposed on the rear side of the lower plate, there is an effect that the control circuit can be protected well.
