Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-fogging device for a head plate installed in, for example, a bathroom, and more particularly to a device for easily preventing or removing fogging of a head plate surface due to steam during bathing. is there.

[0002]

2. Description of the Related Art Generally, in order to prevent the surface of a head plate from being fogged, the surface temperature of the head plate needs to be always higher than the ambient temperature. It is sufficient to raise the surface temperature by at least 6 ° C. above the ambient temperature.

Conventionally, such an anti-fog device for a head plate has an electric heater attached to the back surface of the head plate at present.

[0004]

However, when the above-described head plate with the anti-fog device of the conventional structure is installed in a bathroom,
If the electric heater is connected to a power supply with a voltage of 100 volts, there is a risk of electric shock because the electric heater has poor moisture-proof performance.

In order to prevent such an electric shock, a voltage is used at a low voltage. For this purpose, a low-voltage power supply must be used.

Further, the heater capacity is reduced in order to ensure safety, and even when the electric heater is continuously energized,
Since the heater temperature is set so as to be higher than the ambient temperature only by 20 to 25 ° C., it takes 20 to 30 minutes to perform the anti-fog treatment.

In addition, even if the heater capacity is increased, there is a problem that it is difficult to control the temperature distribution of the entire end plate so as to be uniform.

[0008]

An object of the present invention is to provide a head plate defogging apparatus capable of performing a head plate defogging process in a short time and uniformly controlling the temperature distribution of the entire head plate. is there.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. As shown in FIG. 2, reference numeral 1 in FIG. 2 forms a bathroom installed in an apartment house or the like. Unit bathroom.

In the bathroom 1, a bathtub main body 2 and a washing room main body 3 are installed in combination, and their peripheral surfaces are
A mirror plate 10 is provided on the upper side wall surface 5 of the counter section 6 formed stepwise on the washing place main body 3 while being surrounded by the side wall surface 5. It is a mirror surface.

As shown in FIGS. 1 and 3, the end plate main body 10 is held by a decorative panel 12 via a plurality of fixing fittings 11, and a back surface 10b of the end plate main body 10 is provided with a hot water supply mechanism. An anti-fogging device 20 is provided.

As shown in FIG. 4, this anti-fog device 20
A heat exchange box 21 is provided, and at the bottom of the heat exchange box 21, a hot water supply port 22 and a drain port 23 are provided, and the hot water supply port 22 is supplied with hot water H / W from a hot water supply device (not shown). The hot water supply piping system is connected.

An outlet pipe 25 connected to the hot water supply port 22 via a valve element (solenoid valve) 24 is provided at an upper portion in the heat exchange box 21. A plurality of hot water outlets 26 are formed with openings.

That is, the hot water pipe 25 disperses hot water H / W supplied from a hot water supply piping system from each hot water jet port 26, and a front surface 21a in a heat exchange box 21 in which the end plate body 10 is in close contact. The end plate body 10 is heated from the back surface 10b side, whereby the front surface 10a of the end plate body 10 can be heated with a uniform temperature distribution over the entire surface. .

In the drawings, reference numerals 31 and 32 denote mounting brackets provided on the back surface 21b of the heat exchange box 21 and the side wall surface 5 of the bathroom 1, respectively.
The end plate main body 10 with the anti-fog device 20 can be attached to the side wall surface 5 of the bathroom 1.

According to the above configuration, in order to prevent the surface 10a of the head body 10 from fogging due to steam in the bathroom, the valve body 24 is opened in advance before bathing and the heat is released. Hot water H / W from the hot water supply piping system is supplied into the exchange box 21, and the spout hot water pipe 25 provided at the upper part in the heat exchange box 21.
The hot water H / W is diffused from the hot water spout 26.

Thus, the hot water outlet 2 of the hot water pipe 25
The hot water H · W radiated from 6 flows down to the front surface 21a in the heat exchange box 21, heats the back surface 10b side of the end plate body 10, and has a uniform temperature distribution over the entire surface 10a of the end plate body 10. , The surface temperature of the head body 10 can be always higher than the ambient temperature.
The fogging of the surface 10a of the head body 10 is prevented.

In order to remove the fogging of the fogged surface 10a of the head body 10, when the solenoid valve 24 is opened, hot water H / W from the hot water supply piping system is supplied into the heat exchange box 21.
Hot water H / W is dissipated from a hot water outlet 26 of a hot water pipe 25 provided at an upper portion in the heat exchange box 21.

At this time, the hot water HW discharged from the hot water outlet 26 of the hot water pipe 25 is supplied to the front surface 2 in the heat exchange box 21.
1a to heat the rear surface 10b side of the head body 10 and to heat the front surface 10a of the head body 10 with a uniform temperature distribution over the entire surface.
Can be made higher than the ambient temperature, and the fogging of the surface 10a of the head body 10 is removed in a short time (2 to 3 minutes).
