Abstract

PURPOSE:To increase comfortableness and provide a very sanitary toilet room by using a non-contact type reflection sensor to constitute the switch of an illumination control box in an illumination unit in which brightness and color are variable. CONSTITUTION:In the automatic mode, when somebody sits on the seat of a toilet stool 2 and a seat sensor is turned on, an illumination control box 10 darkens illumination and turns the color tone to blue and, when a man urinates and a lid open sensor is turned on, sets the illumination to intermediate brightness and turns the color tone to blue. In the case of face washing, a human sensor 9 is turned on and the illumination is made brighter and the color tone is turned to red. In other cases, the illumination is bright and the color tone is turned to white. When a user manually sets the illumination mode, a reflection type sensor is turned on by simply putting hands over the sensor and when the hands approach the sensor the color tone is turned from blue to red and the brightness can be freely varied; after a certain time the manual mode is automatically changed to the automatic mode without using a turnover switch.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for improving a toilet room and a lighting control box for the toilet room.

[0002]

2. Description of the Related Art Illumination in a toilet room is usually an incandescent lamp or a white fluorescent lamp. On the other hand, a toilet room that doubles as a makeup room suitable for makeup and grooming is becoming popular.

[0003]

However, when the illumination is an incandescent lamp or a fluorescent lamp, the color and illuminance are constant, and it is too unconventional to confirm the finish of makeup and grooming. In addition, it is preferable that the color tone of the lighting can be changed even in the toilet room, because there is a difference in preference among individuals.

That is, it is an object of the present invention to provide a lighting system capable of arbitrarily changing the illuminance and the color tone of lighting in a toilet room.

[0005]

[Means for Solving the Problems] In order to achieve the above object,
The present invention is characterized in that the toilet room is provided with a lighting unit whose brightness and color can be changed.

Further, the switch of the lighting control box for controlling the lighting unit is constituted by a non-contact reflection type sensor.

[0007]

[Operation] The brightness and color tone of the lighting in the toilet room are adjusted automatically or manually.

The lighting control box for controlling the lighting unit is sanitary because the switches can be operated without directly touching it.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view of a main part of a toilet room according to the present invention. In the toilet room 1, a Western-style toilet 2 and a piping case 3 accommodating a water supply pipe and a drain pipe for the Western-style toilet 2,
A washbasin 6 including a washbasin 4 and a counter 5, a large mirror 7 on the wall, and a lighting unit 8 on the ceiling are arranged.

On the front surface 3a of the piping case 3, a lighting control box 10 is fitted at a side position of the western-style toilet 2, and a human detection sensor 9 is fitted at a position below the washbasin 4, respectively.

FIG. 2 is a front view of the lighting control box according to the present invention, and FIG. 3 is a plan view thereof. As shown in FIG. 3, the lighting control box 10 has a transparent sheet 11 on the front surface.
The light emitting element 12 and the light receiving element 13 are covered with
Reflective sensors 14, 15, 16, 17 with a set of
, And a light emitting diode 18 indicating the degree of color tone and a light emitting diode 19 indicating the degree of brightness are embedded. These diodes 18 and 19 are electrically connected to a printed circuit board (not shown) inside the lighting control box 10. In FIG. 2, 20 is a handprint mark.

FIG. 4 is a partial view of the Western-style toilet according to the present invention. The Western-style toilet 2 has a lid opening sensor 23 which is turned on when the lid 22 of the Western-style toilet is opened, and an ON when the person sits on the toilet seat 24. And a seating sensor 25
25 is connected to the lighting control box 10 of FIG.

FIG. 5 is a diagram of a lighting unit according to the present invention. In the lighting unit 8, a red lamp 28, a blue lamp 29, a green lamp 30 and two half mirrors 31, 31 are housed inside a lighting housing 27. The lower surface is fitted with the Fresnel lens 32, and the upper part is provided with the dimmer 33.

The three primary colors of light are "red,""blue," and "green."
It is well known to properly mix the various colors to produce various colors, so the cable 34 from the lighting control box 10
After that, the dimmer 33 that has received the signal changes the illuminance of each of the lamps 28 to 30 by changing the voltage, for example. The light from each of the lamps 28 to 30 goes straight as shown by the arrow, and some of the light is reflected by the half mirror 31, mixed, expanded by the Fresnel lens 32, and irradiated into the toilet room 1.

The Fresnel lens 32 is a concave lens composed of several concentric ring-shaped lenses and is characterized in that the lens can be made thin.

The operation of the toilet room and the illumination control box of the toilet room having the above-mentioned configuration will be described below. FIG. 6 is a pattern diagram of a toilet room and a lighting control box of the toilet room according to the present invention. “Auto” in the mode means that all the sensors 9, 23 and 25 in FIG. When 25 has been turned on for a certain period of time (for example, 10 minutes), it is automatically selected and the auto lamp 35 of FIG. 2 is turned on.

In the automatic mode, when a person sits on the toilet seat 24 for stool and the seating sensor 25 is turned on, the lighting control box 10 (correctly, the built-in controller) sets the lighting to dark and the color tone to blue.

Further, in the case of men's small use, the lid opening sensor 23 is
Since it is turned on, the lighting is set to medium brightness and the color tone is set to blue.

In the case of the washroom, since the human detection sensor 9 is turned on, the illumination is bright and the color tone is set to red.

In other cases, a bright and white color tone is set.

On the other hand, when the user changes the setting according to his or her preference, as shown in FIG. 3, by holding the hand in front of the reflective sensor 14, the sensor 14 is not touched. Can be turned on.

For example, when a hand approaches the reflection type sensor 14 of FIG. 2, the color tone changes stepwise from blue to red. Similarly, the color tone and the brightness can be freely changed by bringing the hand close to the other reflection type sensors 15 to 17.

However, the manual setting automatically becomes automatic after a certain period of time (for example, 10 minutes. Adjustment is possible by changing the setting of the timer). The reason for this is that the automatic manual changeover switch is omitted.

Further, since it is not necessary to touch the lighting control box 10, the sanitary condition does not become unsanitary and it is extremely comfortable.

The configuration of the front surface of the illumination control box 10 is not limited to that shown in FIG. 2 and may be changed. In short, it is sufficient that the illumination unit 8 can be changed in brightness and color tone.

Further, the illumination unit 8 is of a type in which color is changed by superimposing color filters, or 3 in one bulb.
It may have a built-in color gun.

[0028]

As described above, according to the present invention, since the switch of the lighting control box for controlling the lighting unit is constituted by the non-contact type reflection type sensor in the toilet room, the brightness and color of the lighting can be adjusted according to the preference. Adjustable for increased comfort.

In particular, when the bathroom doubles as a restroom, makeup and grooming in the toilet room become more comfortable.

Further, if the switch of the illumination control box is composed of a non-contact type reflection type sensor, it is not necessary to directly touch the switch, which is extremely hygienic.
