Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indicator light for a sanitary washing device which allows a user to visually identify a function.

2. Description of the Related Art As a conventional indicator light for a sanitary washing device, there is, for example, one disclosed in Japanese Utility Model Laid-Open No. 5-10582. FIG. 4 shows a conventional indicator light for a sanitary washing device. A light emitting window 13 is opened on the upper end wall of the chamber 4a in accordance with the position of the indicator light 12. The light projecting window 13 has a circular opening. A protective cover 13a is formed in a conical shape extending downward from the opening edge of the light projecting window 13, and is further raised from the lower end of the protective cover 13a and integrated with the front surface of the upper casing 4 to form a sleeve 13b. Is provided. The protective cover 13a is positioned so as to be substantially coaxial with the indicator light 12, emits light only from the light projecting window 13 on its upper surface, and is otherwise blocked by the protective cover 13a. With such an assembly, the indicator lamp 12 has the light emitting window 1 of the upper casing 4.
The three portions are covered, and a substantially upper half of the indicator light 12 is surrounded by a protective cover 13a. Therefore, the substrate 1
By just covering the upper casing 4 on 1, the area around the indicator light 12 can be covered. Further, since the indicator light 12 fits completely in the protective cover 13a, no light leaks out to the light emitting window 13 from which light is emitted.
Since light is emitted only from 3, the display sheet 4b can be illuminated properly without scattering of light or reduction in luminance.

However, in the conventional invention, a gap occurs between the substrate 11 and the casing 4 due to a problem in processing accuracy at the time of molding, and the coaxiality of the light projecting window 13 and the indicator lamp 12 cannot be obtained. There are cases. In addition, if a displacement occurs during assembly, problems such as an incorrect display from the light emitting window and an inability to assemble because the indicator light 12 does not fit in the protective cover 13a occur. The present invention aims to eliminate the above disadvantages.

According to the first aspect of the present invention, there is provided a sanitary washing toilet seat in which a casing containing an electrically controlled functional unit is fixed to a toilet body, wherein a board provided inside the casing is provided. An indicator light attached to the substrate to display an operation status of the functional unit; a holder disposed to wrap around the indicator light and transmitting the light of the indicator light; and the indicator provided on the casing. A light emitting window for emitting light from a lamp to the outside, wherein the holder is larger than the light emitting window. According to the first aspect of the invention, since the holder is made larger than the light emitting window, even if the light emitting window and the indicator light are misaligned, light is emitted from the entire surface of the holder on the light emitting window side. Deviation can be tolerated, and the light of the indicator lamp can be emitted from the light emitting window. In addition, the problem that the protective cover and the indicator light interfere with each other and are not assembled due to the misalignment is eliminated. The invention according to claim 2 is characterized in that the holder is attached to the substrate. By attaching the holder to the substrate, the coaxial relationship between the holder and the indicator light can be accurately obtained, and problems such as the holder not covering the indicator light can be eliminated. The invention according to claim 3 is characterized in that an LED is used for the indicator light.
By using an LED as the indicator light, it is possible to provide a display that is inexpensive, consumes less power, and that is easily discernible to the user. The invention of claim 4 is characterized in that the brightness of the light from the light emitting window can be adjusted to an arbitrary size by changing the transmittance of the holder. By changing the transmittance of the holder, the brightness of the light emitted from the light emitting window can be adjusted to an arbitrary size suitable for the user. Also, by lowering the transmittance in the side direction of the holder, it is possible to suppress the interference of light from the adjacent indicator lamps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of the indicator light for a sanitary washing toilet seat according to the present invention will be described. FIG. 1 is a sectional view of an indicator light for a sanitary washing toilet seat embodying the present invention. The casing 3 containing the functional part 2 of the sanitary flush toilet seat is fixed to the toilet body 1 as shown in FIG. On the upper surface of the substrate 5 housed inside the casing 3, LEDs 6 as indicator lights are arranged. For example, a cylindrical holder 7 is disposed above the LED 6 so as to cover the LED 6. The holder 7 is made of a transparent material, and transmits the light of the LED 6. Further, since the holder 7 is fixed to the substrate 5 on which the LEDs 6 are provided, the coaxial A between the LED 6 and the holder 7 can be accurately determined. A light projecting window 8 is provided in the casing 3 above the holder 7, so that light transmitted through the holder 7 is emitted to the outside. An operation nameplate 9 made of a polyester film or the like as shown in FIG. 3 is attached to the outer surface of the casing 3, and the operation nameplate 9 is also provided with a display window 10. In this embodiment, the operation nameplate 9 is attached to the outer surface of the casing 3, but the operation nameplate 9 may not be provided. When the user sits on the toilet main body 1, LE released from the display window 10 of the operation nameplate 9 in FIG.
The operation state of the functional unit 2 can be seen at a glance by the light of D6. The casing 3 has a large shape and includes a certain error in the forming process. Therefore, it is difficult to strictly maintain the coaxial A of the LED 6 arranged on the substrate 5 and the light emitting window 8 of the casing 3,
When there is a large deviation, there is a problem that the light from the LED 6 does not reach the light projecting window 8. The light from the LED 6 is the light emitting window 8
, The brightness of the LED 6 emitted from the display window 10 of the operation nameplate 9 in FIG. 3 is reduced, which may cause the user to misunderstand the operation state. By providing the LED 6 with a cylindrical holder 7 larger than the diameter of the light projecting window 8,
Even if the ED 6 is misaligned, light is emitted from the entire surface of the holder 7 on the side of the light emitting window larger than the diameter of the light emitting window 8,
The light from the LED 6 can be reliably transmitted to the light emitting window 8. Therefore, the LED from the display window 10 of the operation nameplate 9 in FIG.
Since no light is emitted, erroneous recognition due to a decrease in luminance is eliminated. Even if the coaxial A of the casing 3 and the holder 7 is shifted,
Since there is no protrusion between the inner surface of the casing 3 and the holder 7,
There is no problem of assembly failure due to interference, and a certain error during molding and assembly can be tolerated, so that cost can be reduced. When the brightness of the LED 6 is too high, the transmittance of the holder 7 is reduced, and the brightness emitted from the display window 10 of the operation nameplate 9 can be set to an arbitrary size suitable for the user. In addition, by reducing the transmittance of the side surface of the holder 7, it is possible to prevent light interference between the adjacent LEDs 6. In the present embodiment, the LED 6 serving as an indicator light is provided in the function unit 2 inside the casing 3 fixed to the toilet body 1, but when a separate remote controller is used for operating the function unit 2. The present invention can be used as an indicator for identifying the operation state of the remote controller.

According to the indicator light for sanitary washing toilet seat according to the present invention, the LED 6 is provided with the holder 7 having a larger area than the light emitting window 8.
, The light from the LED 6 can be reliably transmitted to the light projecting window 8, and the light is emitted from the display window 10 of the operation nameplate 9, so that erroneous recognition of the operation due to a decrease in luminance is eliminated. In addition, since a certain error can be tolerated during molding, assembly failure can be eliminated and cost can be reduced.
