DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a Western-style toilet attached to a Western-style toilet.

[0002]

2. Description of the Related Art It is very important for health management to check the color and other conditions of stool and urine. However, Western-style toilets tend to have insufficient brightness because the stagnation portion of the toilet is recessed. In particular, stools could not be sufficiently observed due to lack of brightness for elderly people who need more observation for health management. In order to make up for the inconvenience, it is conceivable to illuminate the interior of the Western style toilet with a flashlight etc., but it is inconvenient,
In practice, this is not likely to happen.

As a device for solving this problem, Japanese Utility Model Application No. Sho 5
3-177198 (Japanese Utility Model Application Laid-Open No. 55-90400) and Japanese Utility Model Application No. 54-8698 (Japanese Utility Model Application No. 55-110585).
Etc. have been filed.

[0004] However, both of these devices have the following problems. That is, in both of the inventions, a manual switch provided on a wall or the like or a pressure-sensitive switch provided on a toilet seat is used as a switch unit for lighting the illumination.

[0005] If it is a manual switch provided on a wall or the like,
Each time a stool is observed, the switch must be turned on and off.
Further, since the pressure-sensitive switch provided on the toilet seat is turned on only when the user is sitting on the toilet seat, it is necessary to observe the stool from the crotch while sitting. In addition, the user may forget to turn off the switch once turned on. In particular, it is considered that many elderly people who need to observe the color of the stool or the like often forget to turn off the stool.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a lighting device for a Western-style toilet bowl which can observe a stool in a standing state without having to turn on and off a switch to observe the stool. It is intended to be.

[0007]

A lighting device for a Western-style toilet according to the present invention is provided on the back side of a toilet seat of a Western-style toilet and illuminates the interior of the toilet body, and a switch unit for turning on and off the illumination unit. And a timer section that is turned off after a predetermined time has elapsed since the switch section was turned on.

The lighting section is detachable on the back side of the toilet seat.

Further, the switch section is turned on when the weight applied to the toilet seat exceeds a preset value, and when the weight applied to the toilet seat thereafter falls below the value.
