Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface of a mirror plate such as a vanity table, a surface of a transparent plate such as a window glass of a house, and a display surface of a display device such as a liquid crystal device related to a wristwatch and a mobile device. It belongs to the technical field of an anti-fog device for performing anti-fog. The present invention further belongs to the technical field of a display device such as a head plate, a transparent plate and a liquid crystal device to which such an anti-fog device is attached.

[0002]

2. Description of the Related Art Conventionally, as this type of anti-fog device, there is, for example, a type built in a vanity stand. More specifically, in this type of vanity with a built-in anti-fog device, a glass plate constituting a head plate and a high reflectivity made of Al (aluminum), Hg (mercury), and the like disposed on the back side thereof are provided. A heat ray made of a transparent or opaque metal is built in between the metal film and further behind the metal film. Then, by turning on the anti-fog switch on the switch panel of the vanity stand, power is supplied to the hot wire, the temperature of the hot wire rises, and accordingly the surface of the head plate also rises in temperature and condenses on the surface. It is configured to prevent fogging by reducing the amount of moisture generated.

[0003]

However, since the above-described anti-fog device is built in a vanity stand or the like, a vanity table without the anti-fog device is installed in the vanity stand. It is impossible at home to change to a bathroom vanity that does this, and even if it is brought into a factory, it is practically difficult or impossible. That is, in order to add the anti-fog function, it is necessary to change the basic design of the vanity, and when the anti-fog function is required, the vanity itself must be replaced in practice. There is a problem that there is no. In particular, if the vanity itself is replaced, this will lead to a very serious problem in Japan today that wastes resources and increases industrial waste.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems. For example, it is relatively easy to apply a fogging method to a mirror plate such as a vanity table, a transparent plate such as a window glass of a house, or a display device such as a liquid crystal device. It is an object to provide a fogging prevention device to which a fogging function can be added, and a display device such as a mirror plate, a transparent plate, and a liquid crystal device to which such a fogging prevention device is attached.

[0005]

In order to solve the above-mentioned problems, a fogging prevention device according to the present invention comprises: a transparent electrode film; mounting means for mounting the transparent electrode film on a surface of an object to be fogged; Voltage applying means for applying a voltage to the transparent electrode film.

According to the anti-fogging device of the present invention, the transparent electrode film is mounted on the surface of the anti-fog object by the mounting means. Thereafter, during operation, a voltage is applied to the transparent electrode film by the voltage applying means. Then, on the transparent electrode film,
Heat is generated according to the electric resistance and the applied voltage, and heats the surface of the object to be fogged. That is, the fogging prevention device functions as a heat source, for example, in the same manner as the heater in a bathroom having a built-in fogging prevention heater or a mirror plate attached to a vanity stand. As a result,
It is possible to effectively prevent clouding on the surface of the anti-fog object and condensation of water vapor on the surface. Moreover, since the heat source is a transparent electrode film, even if the heat source is attached to the surface of the end plate or the like, the original function of the end plate or the like is hardly impaired.

As described above, for example, a vanity plate for a vanity table or a bathroom, a transparent plate such as a window glass for a residential or passenger car or a ship, a display device for a wristwatch or a mobile device, etc.
Even when a fogging prevention heater or the like is not built in, the fogging prevention function can be relatively easily realized by attaching the fogging prevention device of the present invention. In particular, for example, in order to add an anti-fog function to the end plate of a vanity counter, it is possible to prevent waste of resources or generation of waste as compared with a traditional technique in which the vanity must be replaced together. Above is very advantageous.

In one embodiment of the present invention, the transparent electrode film is made of an ITO film.

According to this aspect, by applying a voltage to the transparent electrode film made of the ITO film, a temperature rise effective for preventing fogging can be obtained. At this time, if an ITO film is used, a transparent electrode film having a specific resistance suitable for preventing fogging and having a sufficiently high transmittance can be relatively easily constructed.

In another aspect of the present invention, the apparatus further comprises a transparent resin film, and the transparent electrode film is formed on the resin film.

[0011] According to this structure, ITO is formed on a transparent resin film such as polycarbonate or polyarylate.
Since a transparent electrode film such as a film is formed, a transparent electrode film having relatively high reliability and suitable for preventing fogging can be obtained relatively easily. In addition, the resin film can be given mechanical strength, especially if the resin film is attached to the surface of the anti-fog object by the attachment means, the possibility of damage to the transparent electrode film during attachment is reduced. It is more advantageous because it can be performed.

In another aspect of the present invention, the apparatus further comprises a transparent protective film provided on the surface of the transparent electrode film.

According to this aspect, since the protective film is formed on the surface side of the transparent electrode film (that is, on the side opposite to the surface facing the surface of the object), the protective film is attached to the surface of the object to prevent fogging. The later transparent electrode film can be protected from moisture, moisture, mechanical scratches and the like. On the other hand, the back side of the transparent electrode film (ie,
The side facing the surface of the object) can be protected by the object, so that the transparent electrode film can be protected from both sides.

In another aspect of the present invention, the device further comprises a transparent protective film provided on the back side of the transparent electrode film.

According to this aspect, since the protective film is formed on the back surface side of the transparent electrode film (that is, on the side facing the surface of the object), the transparent film after being attached to the surface of the object to prevent fogging is formed. The electrode film can be protected from moisture, moisture, mechanical scratches and the like. In particular, if a protective film is provided on both the front side and the back side of the transparent electrode film, the transparent electrode film can be more reliably protected.

In this aspect, the protective film may be made of a material containing fluorine.

According to this structure, moisture can be repelled by the protective film made of a material containing fluorine. For example, the antifogging device can be used in a highly humid or humid environment such as a bathroom or a vanity stand. It is possible to effectively prevent deterioration of the constituent transparent electrode film due to moisture or moisture. In particular, when the transparent electrode film is made of an ITO film, the oxidation of the ITO film can be effectively prevented.

The material containing fluorine may contain, for example, both ITO and fluorine.

In another aspect of the anti-fog device of the present invention, the attaching means is made of an adhesive applied to the back side of the transparent electrode film.

According to this aspect, the fogging prevention device can be mounted on the surface of the object by a relatively simple operation of attaching with an adhesive. That is, a fogging prevention function can be added to a mirror plate, a transparent plate, a display device, or the like that does not have a fogging prevention function.

In this aspect of the adhesive, the adhesive may be applied to the back surface of the transparent electrode film along the edge of the transparent electrode film.

According to this structure, the anti-fog device is attached to the object along the edge of the transparent electrode film. Therefore, even if the adhesive is opaque, the reflection, transmission, or display on the surface of the object is possible. It is hardly a hindrance. On the other hand,
For example, the fogging prevention device can be generally stably fixed by sticking along edges, such as sticking along four sides of a transparent electrode film having a rectangular planar shape.

In this aspect of the adhesive, the adhesive is transparent, and may be applied to the entire rear surface of the transparent electrode film.

According to this structure, the anti-fog device can be securely attached to the surface of the object by the adhesive applied to the entire back surface of the transparent electrode film. Since the adhesive is transparent, it hardly interferes with reflection, transmission or display on the surface of the object.

Alternatively, in the adhesive according to the aspect, the adhesive may adhere the back surface side of the transparent electrode film to the surface of the object in an airtight manner.

According to this structure, it is possible to effectively prevent a situation in which moisture, moisture, air, or the like enters between the transparent electrode film and the surface of the object and deteriorates the transparent electrode film.

In another aspect of the present invention, the voltage application means includes one terminal connected to one end of the transparent electrode film and another terminal connected to the other end of the transparent electrode film. A voltage source for applying a voltage between the two terminals; and a switch for controlling on / off of voltage application by the voltage source.

According to this aspect, by applying a voltage between one terminal connected to one end of the transparent electrode film and the other terminal connected to the other end by the voltage source, the transparent electrode film is formed. Good heat is generated. Then, by the on / off control by the switch, the voltage application by such a voltage source can be selectively turned on / off.

In this aspect, the one terminal and the other terminal extend along the edge of the transparent electrode film at positions opposed to each other with the transparent electrode film interposed therebetween, and have a higher specific resistance than the transparent electrode film. May be formed from conductive rod-shaped members each having a small size.

With this configuration, it is possible to apply a voltage to the transparent electrode film relatively uniformly from the conductive rod-shaped members extending along the edge of the transparent electrode film, respectively.
The entire transparent electrode film can be relatively uniformly heated. As a result, the surface of the object can be prevented from fogging almost uniformly.

In the aspect including the switch, when the switch is mounted by the mounting means,
You may comprise so that it may be located in the peripheral part of the surface of the said target object.

With this configuration, since the switch is located at the periphery of the surface of the object, the switch itself hardly interferes with reflection, transmission, or display on the surface of the object. In addition, for the user facing the surface of the object, the switch is advantageously located at a position that is easy to see and operate.

[0033] In another aspect of the present invention, the voltage application device is waterproof.

According to this embodiment, since the voltage applying device is waterproof, it can be used, for example, for a mirror plate such as a bathroom or a vanity table, a transparent plate such as a window glass of a house or an office building or a passenger car or a ship, a wrist watch or an outdoor use. The anti-fog device can be suitably applied to an object placed in an environment with high moisture or humidity, such as a display device of a mobile device.

In another aspect of the present invention, the voltage applying means uses a voltage supplied from an external power supply.

According to this aspect, for example, the transparent electrode film can be heated by using a voltage supplied from a household AC power outlet. At this time, in the voltage application device, the AC voltage may be applied after being changed to the DC voltage, or may be applied as the AC voltage or after the transformation.

Alternatively, in another aspect of the present invention, the voltage applying means uses a voltage supplied from a battery.

According to this embodiment, the transparent electrode film can be heated by using a voltage supplied from, for example, a dry battery or a storage battery. Therefore, a fogging prevention function can be easily added to an object that may be used in a place where there is no power distribution facility, such as a display device of a portable device such as a wristwatch or a mobile device, so that practical use is possible. It is very convenient.

In another aspect of the present invention, the transparent electrode film has a predetermined plane pattern in a plane facing the surface of the object.

According to this aspect, since the transparent electrode film has a predetermined flat pattern such as a strip shape or a zigzag shape, the electric resistance required for heat generation is reduced by the flat width or the flat width of the transparent electrode film through which current flows. Can be adjusted by length.

The head plate of the present invention is provided with the above-described fogging prevention device of the present invention (including its various aspects).

According to the head plate of the present invention, a fogging prevention function can be relatively easily added to a head plate for a bathroom or a bathroom vanity having no fogging prevention function. Therefore, it is very advantageous in simplifying the manufacturing process and the apparatus configuration and reducing the cost.

The transparent plate of the present invention is provided with the above-described fogging prevention device of the present invention (including its various aspects).

According to the head plate of the present invention, a transparent plate for a window glass of a general house, an office building, a passenger car or a ship, etc., which is relatively simple for a transparent plate having no anti-fog function. Fog prevention function can be added. Therefore, it is very advantageous in simplifying the manufacturing process and the apparatus configuration and reducing the cost.

The display device of the present invention is provided with the above-described fogging prevention device of the present invention (including its various aspects).

According to the display device of the present invention, a liquid crystal device and an organic EL (Electro-Lumi
An anti-fogging function can be added relatively easily to a display device or the like for a device that does not have an anti-fogging function. Therefore, it is very advantageous in simplifying the manufacturing process and the apparatus configuration and reducing the cost.
