JP2002271716A - Bath room with display means - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a bath room with a display means that utilizes a hot exhaust exhausted as a result of air circulation aiming at reducing a temperature of a hot source generating heat such as a power supply section and a lamp light source or the like existing in a display device for preventing a transparent water-proof cover from being fogged. SOLUTION: The hot exhaust from the thermal generating circuit source of the display device installed in a bath room is led to the transparent water proof cover by using an exhaust duct to increase the temperature of the transparent water proof cover thereby preventing a temperature difference from the temperature of air in the bath room resulting in preventing deposition of water vapor due to the environment with high humidity or is blown onto the transparent water proof cover to blow out water vapor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom with display means provided with a fogging prevention function so as not to hinder the projection function of a display device used in a bathroom.

[0002]

2. Description of the Related Art Conventionally, the demand for enjoying images such as movies and videos while taking a bath has been increasing along with a change in lifestyle, as disclosed in Japanese Patent Application Laid-Open No. 5-115388. The company is finding ways to make it easier to view images in high-humidity atmospheres, such as installing a de-fog heater on the front of the TV set in the bathroom.

[0003]

In the conventional method, a heat generating device such as a heater is newly required in order to prevent the transparent waterproof cover from fogging, separately from the above-mentioned display device.
As a result, the number of components has increased, the product unit price has increased, and wasteful energy consumption has been performed.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a heat source that generates heat, such as the power supply unit or the lamp light source unit, in the display device. In addition, heat exhaust generated by forcibly circulating air with the aim of lowering the temperature of the heat source can be used as a fogging prevention application for the transparent waterproof cover.

[0005]

Means for Solving the Problems and Action / Effect In order to achieve the above object, a first aspect of the present invention is to introduce a heat exhaust source from a heat generating source of a display device installed in a bathroom to a transparent waterproof cover so that the transparent waterproof cover is provided. The temperature of the waterproof cover rises, the temperature difference with the air in the bathroom can be reduced, and the adhesion of water vapor in a high humidity atmosphere can be prevented.

Further, if the heat exhaust gas discharged from the heat exhaust device is used like an air curtain in front of the transparent waterproof cover, there is an effect that a high-humidity atmosphere is not brought close. The steam attached to the transparent waterproof cover can be blown off or evaporated by heat.

In order to achieve the above object, a second aspect of the present invention is to prevent the adhesion of water vapor from the bathroom side by ejecting the thermal exhaust gas discharged from the thermal exhaust device to the bathroom side of the transparent waterproof cover. Alternatively, the effect of removing attached water vapor to prevent fogging that hinders image projection or display can be obtained.

In order to achieve the above object, a third aspect of the present invention is to increase the temperature of the transparent waterproof cover from the inside by blowing out the heat exhaust to the display device side of the transparent waterproof cover to increase the temperature of the bathroom. And dew condensation due to a temperature difference between the display device and the display device can be prevented.

In order to achieve the above object, a cooling fan for cooling heated air around the power supply unit and the lamp light source unit by heat exchange by air circulation, and a heat exhaust from the cooling fan are provided. To the transparent waterproof cover, and an exhaust duct for allowing heat exhaust to pass through, it is possible to efficiently transfer the heat of the heat-generating portion without particularly providing a new fan,
The effect of preventing fogging of the transparent waterproof cover can be brought about.

According to another aspect of the present invention, the flow rate can be increased by making the cross-sectional area of the outlet portion smaller than that of the inlet portion of the exhaust duct.
The transparent waterproof cover can be effectively protected from water vapor.

In order to achieve the above object, a sixth aspect of the present invention is to make the exhaust duct flexible without fixing it.
The discharge port can be provided at a target place under various circumstances, and the degree of the fogging prevention effect on the transparent waterproof cover can be freely set by moving the distance closer or further away.

In order to achieve the above object, a seventh aspect of the present invention is to use a transparent and highly versatile glass or acrylic resin as a material of the transparent waterproof cover.
Suitable as a material used in bathrooms.

In order to achieve the above object, a water-repellent coating is applied to the front and back surfaces of the transparent waterproof cover to collect small water droplets such as fogging into large water droplets. Moisture can be efficiently blown off, and in another case, a hydrophilic coating is applied to spread the attached water vapor thinly and evenly on the surface, and drying by hot exhaust efficiently and quickly removes the water vapor. be able to.

In order to attain the above object, the present invention provides a liquid crystal projector having a surface state that does not generate gloss and scatters light, thereby preventing the use of a highlight caused by a liquid crystal projector light source. When a person views a video, it is possible to reduce loads such as highlights on the eyes.
