Abstract

PURPOSE:To allow a defogging mirror that prevents its surface from being fogged due to condensation of vapor to uniformly defog its surface in a short time by heating. CONSTITUTION:This defogging mirror comprises a conductive glass 1 comprising a thin electrically conductive film 6 formed on one side of a transparent plate- shaped glass 5; long, thin plate-shaped electrodes 2a, 2b installed on the surface of the electrically conductive film of the conductive glass at predetermined intervals and receiving the supply of power from a power source; a transparent insulating coat 3 formed to cover the overall surface of the electrically conductive film on that side of the conductive glass on which the electrodes are installed; and a coat 4 of reflecting material formed on the plate-shaped glass side or the electrically conductive film side of the conductive glass, all of which are combined with one another. A current is passed from the electrodes 2a, 2b to the electrically conductive film 6 of the conductive glass 1 to heat the electrically conductive film 6. Condensation on the surface of the mirror is thus evaporated in a short time to remove fog, and uniform defogging is made possible.

2. Description of the Related Art When air containing water vapor comes into contact with a mirror installed in a place with a lot of water vapor such as a bathroom or a washroom or a place where environmental temperature changes greatly, the surface temperature of the mirror is below the dew point of the water vapor. In this case, the water vapor in contact therewith is cooled to cause dew condensation, and the surface of the mirror becomes cloudy. In order to remove or prevent such fog on the mirror surface, anti-fog mirrors have been conventionally provided. This kind of anti-fog mirror is, for example, as described in Japanese Utility Model Laid-Open No. 3-106971, a part of the back side of the mirror having a reflective substance attached to the back side of the glass,
The nichrome wire is formed in a meandering shape and provided with an anti-fog heater attached to an insulating panel or the like. When used in a washroom, etc., the nichrome wire is heated by heating the mirror surface at this temperature by energizing the anti-fog heater from a household power source through a switch, and sticking to the surface. It was supposed to evaporate the formed dew to remove the haze.

However, in such a conventional fog-preventing mirror, since the anti-fog heater is provided on the back surface of the mirror, the temperature of the anti-fog heater does not change even when the nichrome wire is energized and heated. After heating the glass itself having a thickness of about 3 to 5 mm, the temperature on the surface of the mirror began to rise.
Therefore, it takes time for the surface temperature of the mirror to rise above the dew point of water vapor, and it may take, for example, 5 to 6 minutes for the haze on the mirror surface to completely disappear. With this, the user could not wait until the cloudiness of the mirror disappeared, and the user wiped it off with a towel or the like. Further, since the anti-fog heater uses a nichrome wire formed in a meandering shape as a heat source, it is not possible to cover the entire back surface of the mirror all over, and only the portion of the nichrome wire heated by electricity is applied. Even if the fog disappeared well, the fog did not disappear so much in other parts and the peripheral part of the mirror, and unevenness in removing the fog sometimes occurred. In this case, it cannot be said that the anti-fog mirror is fully functioning.

In order to use the defoaming mirror having the above-mentioned structure, for example, when the mirror surface becomes fogged by the use of hot water while being attached to the installation surface 11 such as a washbasin unit, an outlet is previously provided in FIG. The switch 9 is turned on while the switch 8 is connected to a commercial power source (not shown). Then, electric power is supplied to the electrodes 2a, 2b via the lead wires 7a, 7b, and the electrodes 2a, 2b are energized to the conductive film 6 of the conductive glass 1 shown in FIG. As a result, a current flows through the entire surface of the conductive film 6, and the conductive film 6 generates heat and functions as a heater. Then, the insulating coat 3 located on the surface of the mirror is directly heated by the temperature of the conductive film 6 to evaporate the dew condensation adhering to the surface in a short time to uniformly remove the fogging. At this time, as is clear from FIG. 1, since the insulating coat 3 is formed on the entire surface of the mirror on the side of the user who uses it as shown by the arrow A, even if contact is made, electric shock may occur. That's not it. If the switch 9 is turned on in advance and the conductive film 6 is always energized, it is possible to prevent the mirror surface from being fogged by the use of hot water or the like.

FIG. 5 is an explanatory view showing another embodiment of the present invention. FIG. 5 (a) is a front view of the conductive glass 1 and FIG. 5 (b).
Is a sectional view taken along the line BB of (a), and FIG.
It is a C line sectional view. This embodiment is mainly applied to a large mirror. For example, the electrodes 2a and 2b provided on the sides of the conductive glass 1 in the longitudinal direction are connected to a lead wire 7a from a power source whose cross-sectional area is not shown. , 7b, the larger the distance from the supply point of the power supplied through That is, the lead wires 7a and 7b
In the position of BB near the power supply point by
As shown in (b), the electrodes 2a and 2b are formed to have a relatively small cross-sectional area, and at the position C-C far from the power supply point, the electrodes 2a and 2b are disconnected as shown in FIG. 5 (c). The area is formed large. The change in the cross-sectional area is increased at a predetermined rate in proportion to the distance from the power supply point. This is because when the length of the electrodes 2a and 2b becomes large, the potential drops between the connection side of the power source and the side farther from the power source, the flow of current changes, and the current at the remote side decreases, so The area is increased at a constant rate to increase the conductivity so that a constant current flows. In this case, a uniform current flows in the longitudinal direction of the electrodes 2a and 2b, the conductive film 6 of the conductive glass 1 is heated uniformly, and the effect of removing fog in the large mirror can be made substantially uniform.

Since the present invention is constructed as described above,
A conductive film formed over one surface of the conductive glass is heated by heating the conductive film by supplying electricity to the conductive film from electrodes provided on the conductive film surface of the conductive glass at a predetermined interval. The surface of the mirror made of the combination of the conductive glass and the reflective material coat can be heated. As a result, it is possible to vaporize the dew condensation on the mirror surface in a short time to remove the haze, and to remove the moisture uniformly. Particularly, in the case of the embodiment shown in FIGS. 1 and 4 (b), since the conductive film of the conductive glass serving as the heater is located in the immediate vicinity of the mirror surface, the mirror surface is heated in a short time. For example, it is possible to completely remove haze within 30 seconds to 1 minute. Further, since the conductive film is formed on the entire surface of one side of the conductive glass, the conductive film is uniformly heated over the entire surface by the electric current from the electrode, and the mirror surface is uniformly removed to the peripheral portion. can do.
