Description

  The present invention relates to a toilet lid device installed in a Western-style toilet, and more particularly to a toilet lid device in which a toilet lid covers substantially the entire upper surface of a case.

  A toilet seat box is installed on the rear upper surface of the western-style toilet bowl, and Western-style toilet equipment in which a toilet seat and a toilet lid are attached to the toilet seat box so as to be rotatable in the up-down direction is widely used.

  FIG. 6 shows an example of a Western-style toilet equipped with a toilet seat box. A row tank 2 is installed on the rear upper surface of the Western-style toilet 1, and a toilet seat box 3 is installed on the front side of the row tank 2. A toilet seat 4 and a toilet lid 5 are connected to the toilet seat box 3 so as to be rotatable in the up-and-down direction (vertical direction). In the toilet seat box 3, a hot water washing device for washing the buttocks of the toilet seat seated person with warm water is installed. A human body detection sensor is installed in the front part of the upper surface of the toilet seat box 3. Based on the detection signal of the human body detection sensor, the toilet lid automatically opens and closes or the toilet bowl is automatically washed.

  A predetermined gap is provided between the toilet lid 5 and the toilet seat box 3 so as to allow the toilet lid 5 to turn up and down. If the gap is excessively narrowed, the rear edge of the toilet lid 5 hits the toilet seat box 3 when the toilet lid 5 is raised.

  Thus, if there is a gap between the toilet lid 5 and the toilet seat box 3, dust or dust may enter the gap.

As a toilet lid device of the type in which such a clearance between the toilet lid and the toilet seat box does not occur at all, FIGS. 33 and 34 of JP-A-2001-115526 are shown in FIGS. 7 (a) and 7 (b). The toilet lid 10 is pivotally supported by the support shaft 11 on the upper rear edge of the toilet seat box 12. In addition, in FIG. 7, the code | symbol 13 shows a low tank and the code | symbol 14 shows the bowl part for hand-washing.
JP 2001-115526 A

  In the above Japanese Patent Laid-Open No. 2001-115526, there is an inconvenience that a human body detection sensor cannot be arranged on the upper surface of the toilet seat box. That is, if the human body detection sensor is disposed on the upper surface of the toilet seat box 12 in FIG. 7, the human body detection sensor is covered with the toilet lid 10 when the toilet lid 10 is lying down.

According to the present invention, a lying toilet lid covers substantially the entire upper surface of a case such as a toilet seat box, and dust and dirt are prevented from entering the gap between the toilet lid and the case, and a human body detection sensor is also incorporated integrally. An object of the present invention is to provide a toilet lid device that can be used .

The toilet lid device of the present invention (Claim 1 ) includes a case installed on the upper surface of the rear part of a Western-style toilet, a toilet seat attached to the front part of the case so as to be able to turn up and down via a support shaft, and the rear part of the case and a toilet lid mounted for raisably rotating via a shaft, the該便lid in toilet lid device covering substantially the entire seat and the case upper surface when laid down, the trailing edge of該便lid notch A human body detection sensor is provided at the rear part of the upper surface of the case, and the human body detection sensor faces the notch when the toilet lid falls down, A signal light transmission part substantially the same as the notch part is provided, and a human body detection sensor is arranged on the back side of the signal light transmission part .

In such toilet lid device can detect a human body by the human body detection sensor regardless of the state of the toilet lid.

Also, the rear portion of the case upper surface, a large cutout section substantially the same size or even more, the signal light transmitting portion of unique is provided a toilet lid, the human body detection sensor on the rear side of the signal light transmitting unit Since it is arrange | positioned, when a toilet lid lies down, a notch part comes to be visually recognized as a clear pattern, and the external appearance is favorable.

  According to the present invention, the lying toilet lid covers substantially the entire upper surface of the case such as the toilet seat box, and dust and dirt are prevented from entering the gap between the toilet lid and the case, and the human body detection sensor is also integrated. A toilet lid device that can be incorporated is provided.

Hereinafter, reference examples and embodiments will be described with reference to the drawings.

1A and 1B are perspective views of a toilet lid device according to a reference example , in which FIG. 1A shows a state in which the toilet lid is lying down, and FIG. 1B shows a state in which the toilet lid is raised. FIG. 2 is a side view of a Western style toilet equipped with the toilet lid device.

  A toilet seat box 21 is installed on the upper surface of the rear part of the western-style toilet 20, and a toilet seat 23 is attached to the front part of the toilet seat box 21 via a support shaft 22 so as to be able to turn upside down. A toilet lid 24 is attached to the rear upper edge of the toilet seat box 21 via a support shaft 25 so as to be able to turn up and down.

  The front surface of the toilet seat box 21 is a downward slope that is lower on the front side. A bulging portion 21a protrudes from the center of the slope in the left-right direction.

  The toilet seat 23 has extension portions 23a and 23a extending rearward from the left and right rear portions, and the extension portions 23a and 23a are disposed on both left and right sides of the bulging portion 21a.

  The toilet lid 24 has hanging pieces 24 a and 24 a extending along both the left and right sides, and the extended portions 24 a and 24 a at the rear portion of the toilet lid 24 are disposed on the left and right outer sides of the upper portion of the toilet seat box 21. Has been.

  The support shaft 25 protrudes from the uppermost and rearmost side of the right side of the toilet seat box 21 from the front. The support shaft 25 is inserted into the opening 24b of the hanging piece 24a. A sensor unit 26 is attached to the tip of the support shaft 25. The sensor unit 26 includes a cylindrical casing, a human body detection sensor having an infrared light emitting element and a light receiving element arranged in the casing, and an infrared transmitting portion 26a provided in the casing. The support shaft 25 has a cylindrical shape, and a harness (not shown) for connection to the human body detection sensor is inserted through the support shaft 25.

  Although not shown, a drive shaft for raising and lowering the toilet lid 24 is provided on the left side surface of the toilet seat box 21 from the front side. This drive shaft is arranged coaxially with the support shaft 25. The drive shaft is connected to the hanging piece 24 a on the left side of the toilet lid 24. The drive shaft is rotated by a motor disposed in the toilet seat box 21, whereby the toilet lid 24 is turned upside down. This motor is controlled based on the detection signal of the human body detection sensor.

  In the toilet lid device configured in this manner, the toilet lid 24 covers the entire upper surface of the toilet seat box 21, and when the toilet lid 24 is closed, there is no gap for dust and dirt to enter, and the appearance is very good. In addition, a sensor unit 26 is fixedly provided at the tip of the support shaft 25, so that the human body can be reliably detected regardless of the posture of the toilet lid 24 and the toilet seat 23.

Referring to FIGS described form of implementation.

  In this embodiment, a notch 30 is provided at the center in the left-right direction of the rear edge of the toilet lid 24A. The cutout 30 has a shape that gradually decreases in width toward the front of the toilet lid 24A, and in this embodiment, has a substantially arc shape.

  At the rear edge of the upper surface of the toilet seat box 21 </ b> A, an infrared transmission part 31 is provided at a position overlapping with the cutout part 30, and a human body detection sensor using infrared rays is provided on the back side of the infrared transmission part 31. The infrared transmitting portion 31 has a substantially arc shape and is approximately the same size as the cutout portion 30. The infrared transmission part 31 is made of a substantially black synthetic resin. The toilet seat box 21 is made of a light colored synthetic resin such as ivory, gray, or pink.
