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 to blow hot air for drying wet hands.

[0002]

2. Description of the Related Art Conventionally, in a hot-air dryer provided on a wall surface of a toilet, the front side thereof is covered with a front cover, and the front cover is made of metal with emphasis on robustness. Since the front cover is a part that can be easily touched, it must be legally grounded.Conventionally, a ground wire is attached to the outside of the front cover using screws, etc. The wires are exposed to the outside of the front cover, which deteriorates the appearance, and when the front cover is removed when repairing the internal electrical parts, the ground wire hinders the removal of the front cover. was there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has a good appearance, can be grounded, and can be easily attached and detached from a front cover. With the aim of providing a hot air dryer
The gist is a resin base cover attached to a wall of a toilet or the like, a metal base chassis disposed inside the base cover and having electric components such as a fan and a heater directly mounted on the front surface thereof, and a metal base chassis. In the warm air dryer configured by a metal front cover that is fitted to a peripheral portion of the base cover in a lid shape on the front surface of the base chassis and the electric component, when the front cover is fitted to the base cover, Another feature is that a grounding metal, one end of which can abut on the inner peripheral surface of the front cover, is provided along the peripheral edge of the base cover with the other end attached to the base chassis.

[0004]

The grounding metal is provided along the periphery of the base cover, the inner end of the grounding metal is mounted on a metal base chassis, and the outer end is formed by connecting the front cover to the base cover. When it is fitted, it can come into contact with the inside of the front cover, and in this state, the metal front cover and the metal base chassis are connected and connected via the grounding bracket, and the front cover is properly grounded. When the front cover is fitted, the ground metal is in a concealed state, so that the appearance of the hot-air dryer is refreshing. Also, when the front cover is removed from the base cover, there is no need to loosen the screws as in the conventional case, and the mounting and removal of the front cover are easy, and the internal maintenance is easy.

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 transmit a 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. 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 attached, the grounding bracket 18 is in a concealed state, so that the appearance is clear and the front cover 1
6 can be easily detached by pulling it away from the base cover 4, and the front cover 16 can be easily removed and repaired when repairing internal electric parts and the like. Become.

[Effect of the Invention] The present invention is a metal base cover which is mounted on a wall surface of a toilet or the like, and which has electric components such as a fan and a heater mounted on the front surface of the base cover which are directly connected to a power supply. A base chassis, and a warm air dryer comprising a front cover made of metal and fitted to a peripheral portion of the base cover in a lid shape on the front surfaces of the base chassis and the electric components, wherein the front cover is attached to the base cover. By providing a grounding metal that can be in contact with the inner peripheral surface of the front cover at one end when fitted, along the peripheral edge of the base cover with the other end attached to the base chassis. Is fitted to the base cover, and the metal front cover and the metal base chassis are connected through a grounding bracket. Next to the, the front cover satisfactorily can be ground and the ground fitting, since the concealed when the front cover is fitted, the appearance of the hot air drier is that the cleanest. Further, the front cover can be easily attached and detached, and the internal maintenance can be easily performed.
