Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom where projection can be enjoyed.

[0002]

2. Description of the Related Art Due to changes in Western lifestyle, there is a demand to enjoy images such as movies and videos (hereinafter simply referred to as "images") while taking a bath.

A technique of fitting a television receiver to a side wall of a bathroom has been proposed, but when a large screen is desired, a screen and a projector are prepared, and the screen is hung or fitted on the side wall and provided on the opposite side wall. It will be projected from the projector.

[0004]

However, bathrooms in recent years are relatively small, and the side walls surrounding the bathroom have windows, doors, handrails,
It is difficult to secure a screen area because it is equipped with a lot of equipment such as faucets, towel racks, shower hangers, and mirrors. Forcibly providing a screen surface necessitates increasing the floor area of the bathroom itself.

Therefore, an object of the present invention is to provide a technique for paying attention to a window glass and converting the window glass into a screen.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention uses a window glass in a bathroom as a dimmer glass that is milky white when not energized and becomes transparent when energized. Install a projector that projects an image on the side wall.

Further, the window glass has a double glass window structure, the window glass on the indoor side is the light control glass, and the window glass on the outdoor side is a fixed spread angle from the human eye position. The field of view selection glass was opaque in the range and transparent in other areas.

[0008]

When the outside is viewed from the bathroom, the light control glass is transparent, and when it is used as a screen, the light control glass is milky white. The transparent / milky white conversion is performed depending on whether or not the light control glass is energized.

As described above, when the light control glass is made transparent, and there is a possibility that the inside of the bathroom can be seen from the outside, it may be prevented by the view selection glass.

It may be integrated with or separate from.

FIG. 2 is a view taken in the direction of arrow 2 in FIG.
0 is a rectangular glass having an aspect ratio suitable for the screen. Further, since the bay window portion 17 keeps the screen away from the bathtub 3, a person bathing in the bathtub 3 can also see the screen.

FIG. 3 is a sectional view taken along the line 3-3 of FIG. 1. The window glass 20 has a so-called double structure, in which the bathroom side is a light control glass 21 and the outdoor side is a visual field selection glass 31. Since it has a double structure, the air layer A enclosed between the glasses 21 and 31 becomes a good heat insulating material and sound insulating material. 2 in the figure
1a and 31a are rubber packings and are glass 21 and 3
It is a member for fixing 1 to the window frame.

FIGS. 4 (a) and 4 (b) are diagrams showing the operating principle of the light control glass of the present invention. As shown in FIG. 4 (a), the light control glass 21 has a liquid crystal 22 and a resin matrix 23 which are transparent and conductive. It is sandwiched between films 24, 24, and a power source 25 is connected between these transparent conductive films 24, 24.

When the switch means 26 is off (FIG. 4 (a)), the crystal alignment of the liquid crystal 22 is not uniform and the light of the arrow is almost blocked, so that the light control glass 21 is totally opaque milky white. Present. Since the degree of opacity can be easily changed by changing the voltage of the power supply 25, the degree may be set to be suitable for the projection screen.

Next, as shown in FIG. 4B, when the switch means 26 is turned on, the crystal alignment of the liquid crystal 22 is aligned, the light control glass 21 becomes transparent, and the light of the arrow sufficiently passes.

FIG. 5 is an exploded perspective view of the field-of-view selection glass of the present invention. In the field-of-view selection glass 31, a polymer film 32 having special optical characteristics is float plate glasses 34 and 34 with intermediate films 33 and 33 interposed therebetween. It is sandwiched.

FIGS. 6 (a) to 6 (c) are views showing examples of use of the field-of-view selection glass. In FIG. 6 (a), the field-of-view selection glass 31 corresponding to the spread angle θ (for example, 53 °) from the eye 35 is used. Area L1 is opaque, and the other areas are transparent. FIG. 6B shows that when the eyes 35 are brought very close to the field-of-view selection glass 31, for example, when a person in the bathtub 1 brings his face close to the window glass 20 and looks outside, the opaque portion L2 becomes very small, and as a result, Or you can look out from the transparent part by turning your eyes down.

On the other hand, regarding whether or not the user can see from the outside,
As shown in FIG. 6C, a fence 36 may be provided at a position separated from the visual field selection glass 31 by the same dimension as the height L3 of the visual field selection glass 31. That is, the eyes 37 of a person who passes through the fence 36 sees the opaque view selection glass 31 because most of the view selection glass 31 is covered at the angle θ. Therefore, there is no need to worry about being seen from the outside.

The operation of the window glass of the bathroom having the above structure will be described below. FIG. 7 is an operation diagram of the present invention.
