[Problems to be solved by the invention]
Since the lighting device disclosed in JP-A-8-284232 is provided on the sleeve of the toilet seat box, the illumination light is emitted forward so as to pass through the side of the Western-style toilet. For this reason, the brightness in front of the front of the Western style toilet is insufficient. In addition, since the silhouette of the Western-style toilet bowl is reflected on the floor in front of the Western-style toilet bowl, it may be difficult to find when the slippers placed on the floor are on the shadow side of the silhouette.
[0005]
When an LED is provided on a shelf on a wall surface or a lower surface of a remote controller as in JP-A-2001-65032, the floor near the wall becomes bright, but the brightness of the floor in front of the Western-style toilet is insufficient. Increasing the number of LEDs on the shelf or remote control increases the brightness near the Western-style toilet, but it is costly and may be dazzling.
[0006]
Embedding an LED on the side of a Western-style toilet as disclosed in Japanese Patent Application Laid-Open No. 2001-120448 is considerably expensive because the Western-style toilet is made of ceramic. The same issue also states that the toilet seat and the toilet lid are provided with LEDs, but in this case, the toilet seat and the toilet lid do not protrude from the upper surface of the Western-style toilet, and the light from the LED does not extend upward or in the Western-style toilet. And the floor near the Western-style toilet is not so bright.
[0007]
An object of the present invention is to solve the above-mentioned problems of the prior art and to provide an illuminated toilet facility capable of efficiently illuminating a floor in front of a Western-style toilet.
[0008]
[Means for Solving the Problems]
Illuminated toilet equipment of the present invention, in a toilet equipment provided with a toilet seat and a toilet lid on the upper surface of a Western-style toilet, the front end of the toilet seat or the toilet lid extends forward from the upper front edge of the Western-style toilet, The front end is provided with a floor lighting illuminator that irradiates light to the floor in front of the Western-style toilet bowl.
[0009]
According to the illuminated toilet apparatus of the present invention, the floor surface in front of the Western-style toilet is illuminated by the light emitting device provided on the front edge of the toilet seat or the toilet lid. Can be illuminated. The present invention is particularly suitable for a case where the user enters the room without turning on the interior lighting of the entire toilet room at night and uses it under a faint light. When the toilet room is used with such a faint light, it is not dazzling and the cellular activities of the body are not activated by light, so that it is possible to return to bed immediately after stool.
[0010]
In the present invention, since light is emitted from above to the front of the Western-style toilet, a large silhouette does not occur in front of the Western-style toilet, and slippers and the like can be easily found.
[0011]
In the present invention, the light emitting device is provided on the toilet seat or the toilet lid. However, the toilet seat and the toilet lid are usually made of a synthetic resin, and can be easily manufactured so as to incorporate the light emitting device.
[0012]
In one aspect of the present invention, the front edge of the toilet lid extends forward from the front edges of the toilet seat and the Western-style toilet, and the floor lighting illuminator is provided at the front edge of the toilet lid. . The toilet lid is usually a single plate and has a simpler configuration than the toilet seat. Therefore, even if the front edge is extended so as to extend, the manufacturing cost is slightly increased. Further, when the front edge of the toilet lid is extended, in the case of a manual toilet lid, it is easy to hang a fingertip on the front edge and pull it up.
[0013]
When the light emitting device is provided at the front edge of the toilet lid, a rear lighting light emitting device that emits light toward the rear from the front edge of the toilet lid when the toilet lid is standing may be provided. With this configuration, the light radiated rearward from the upper part of the standing toilet lid can illuminate the vicinity of the hand basin and the wall surface behind the Western-style toilet. This makes it easier to use the hand basin and obtains the effect of indirect lighting. Also, if the illuminator for floor illumination does not irradiate light when the toilet lid is upright, and the illuminator for rear illumination does not emit light when the toilet lid is tilted, Light will not be directed to the body. Therefore, since it is not dazzling and the cellular activity of the body does not become active, it is possible to return to bed immediately after stool.
[0014]
When applying the present invention to a Western-style toilet having a toilet lid automatic opening / closing mechanism that automatically opens and closes the toilet lid based on human body detection, after detecting the human body, the timing until the toilet lid is opened may be delayed for a predetermined time. preferable. By doing so, for example, the floor surface in front of the Western-style toilet can be illuminated with the light-emitting device from entering the toilet room and wearing slippers or the like until approaching the Western-style toilet.
[0015]
In another aspect of the present invention, the front edge of the toilet seat extends forward from the upper front edge of the Western-style toilet, and the floor lighting illuminator is provided at the front edge of the toilet seat. .
[0016]
Usually, this toilet seat is provided with a heating heater and the wiring for the heater is provided, so that the wiring for the light emitting device provided at the front edge of the toilet seat can be easily drawn.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a perspective view showing a Western-style toilet apparatus according to an embodiment, wherein FIG. 1A shows a state where a toilet lid is closed, and FIG. FIG. 2 is a sectional view taken along line II-II of FIG. 1, and FIG. 3 is a perspective view showing another embodiment.
[0018]
A ceramic Western-style toilet 1 is installed on the floor F of the toilet room, and a tank cover 2 is installed on the rear upper surface. Inside the tank cover 2, a low tank for storing toilet flushing water, a hot water cleaning device for cleaning the buttocks of a human body with warm water, and the like are provided. This hot water cleaning device includes a cleaning nozzle 3 extending forward. A flush handle 4 for discharging water from the low tank is provided on a side surface of the tank cover 2. A hand washer 5 is installed on the upper part of the tank cover 2, and a hand-washing spout pipe 6 is provided upright on the rear upper surface of the hand washer 5.
[0019]
A toilet seat 7 and a toilet lid 8 are attached to the lower part of the front surface of the tank cover 2 so as to be vertically rotatable. In this embodiment, the toilet lid 8 is of an automatic opening / closing type, and the tank cover 2 is provided with a human body detection sensor and a rotation device (both are not shown).
[0020]
The front edge of the toilet lid 8 extends forward from the front edge of the toilet seat 7 and the front edge of the upper surface of the Western-style toilet 1. A light emitting unit 10 is provided at the front edge of the toilet lid 8. The light-emitting unit 10 includes a substrate 11, an LED 12 for floor illumination provided on a lower surface side of the substrate 11 (a lower surface side in a state where the toilet lid 8 is laid down, the same applies hereinafter), and an upper surface side of the substrate 11. And a light-transmitting resin mold 14 in which the substrate 11 and the LEDs 12 and 13 are embedded. The light emitting unit 10 is fitted to an opening 8 a provided at the front edge of the toilet lid 8 and is fixed to the toilet lid 8.
[0021]
On the ceiling of the toilet room having the Western-style toilet facilities configured as described above, an indoor lighting device (such as an incandescent lamp or a fluorescent lamp) for illuminating the entire toilet room is provided.
[0022]
When a person enters the toilet room, it is detected by a human body detection sensor provided on the tank cover 2 and the LED 12 is turned on as shown in FIG. Illuminated over an area. Therefore, even if the indoor lighting device is turned off at night, the floor surface and the slippers can be visually recognized.
[0023]
After a predetermined time (for example, 3 to 5 seconds, the length of which can be adjusted) after the entrance, the toilet lid 8 is automatically opened (standing).
[0024]

[0025]
Thus, according to this embodiment, when entering the toilet room, the floor F in front of the Western-style toilet 1 is illuminated, so that the Western-style toilet 1 can be easily approached. In this case, since the light from the light emitting unit 10 hardly causes a silhouette in front of the Western-style toilet 1, the visibility of the floor surface F is good, and slippers and the like are easy to find.
[0026]
Further, after entering the toilet room, the toilet lid 8 is kept closed for a while, and the floor surface F is illuminated by the LED 12 during this time, so that there is sufficient time to wear slippers.
[0027]
After the toilet lid 8 stands up, the vicinity of the hand washing machine 5 is illuminated, so that hand washing is easy. In addition, since the light that strikes the handwash 5 and the wall behind it is reflected and the interior of the toilet room is indirectly illuminated, the Western-style toilet 1 can be easily used. Since the LED 12 is turned off after the toilet lid 8 stands up, it is not dazzling.
[0028]
Note that the LEDs 12 and 13 may not be turned on during the daytime or when the indoor lighting fixture is turned on. The toilet lid 8 may be opened immediately after entering the toilet room.
