Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a Western-style toilet that detects the human body using a sensor and causes water to flow into the toilet bowl. For more information,
This invention relates to a Western-style toilet with a human body detection sensor that has an improved sensor installation method.

[Prior Art] An automatic Western-style toilet that senses the human body and automatically flushes water into the toilet is known. This type of self-cleaning Western-style toilet is configured to, for example, detect when a human body is sitting on the Western-style toilet and flush a small amount of water, or detect when a human body leaves the Western-style toilet and flush water. There is.

Conventionally, this human body sensor is attached to the wall of the toilet room on the side of a Western-style toilet.

[Problems to be solved by the invention] In conventional automatic flushing Western-style toilets, the control device that controls the supply of flushing water to the Western-style toilet and the human body detection sensor are placed separately.
Long wiring is required to connect the sensor and the control device, and the wiring construction work is complicated and construction costs are high. In addition, if the wall where the human body detection sensor is installed is quite far from the Western-style toilet, the distance between the sensor and the human body to be sensed will increase, the sensor's human body detection accuracy will decrease, and the automatic flushing system will not operate correctly. There is also a risk that it will be difficult to do so.

[Means for Solving Problems] The Western-style toilet with a human body detection sensor of the present invention has a raised part integrated with the toilet bowl at the rear of the toilet bowl, and a human body detection sensor is installed in front of this raised part. A Western-style toilet with a human body detection sensor, the interior of the rising part is a space, an opening is provided in the front of the rising part, and the back side of the cover covered with the opening is The sensor is provided in the cover, the lower end of the cover is pivotally attached to the toilet seat, and the upper end of the cover is rotatable toward the front of the toilet about the pivot point. It is something.

[Function] In the Western-style toilet bowl equipped with a human body detection sensor of the present invention, the human body detection sensor is provided integrally with the Western style toilet bowl, so the human body detection sensor and the control device are connected directly or with only extremely short wiring. be done.

Further, in the present invention, the distance between the human body to be sensed and the human body sensing sensor is short and approximately constant.

In the Western style toilet bowl with a human body detection sensor of the present invention, the human body detection sensor is provided on the back side of the cover, and by attaching this cover to the upright part of the Western style toilet bowl, the human body detection sensor can be attached to the Western style toilet bowl. be able to. Therefore, the installation work of the human body detection sensor is extremely easy.

In addition, in the Western-style toilet with the human body detection sensor of the present invention, the cover can be rotated so as to fall forward of the Western-style toilet, and by rotating the cover in this way, the maintenance and management of the human body detection sensor is extremely easy. It can be done easily.

[Examples] The present invention will be described in more detail below with reference to embodiments shown in the drawings.

Code 1 is a Western-style toilet, and there is a toilet bowl 2 in the front part.
is provided, and a rising part 3 is provided at the rear part of the toilet bowl 2.
is provided integrally with the Western-style toilet bowl 1.

In this embodiment, the inside of the rising section 3 is a space, and an opening 4 is provided in the front surface of the rising section 3. A cover 5 is provided to cover this opening 4, and a window hole 6 provided in the cover 5
A translucent plate 7 made of a material that transmits light rays such as infrared rays for sensing the human body is attached to the body. Further, a casing 8 is attached to the back side of the window hole 6, and a human body detection sensor 9 and a water supply control device 10 are installed inside the casing 8.

In addition, in this embodiment, a boss portion 5 is provided on the back surface of the cover 5.
a is integrally provided, and a casing 8 is attached to the boss portion 5a by screws 5b. Further, a window frame member 11 is similarly attached to this boss portion 5a with screws 5b, and the plate 7 is fixed to this window frame member 11.

In this embodiment, a projection 12 is provided on the upper surface of the Western-style toilet on the rear side of the toilet bowl 2 integrally with the Western-style toilet 1, and the toilet seat 14 is pivoted by a hinge shaft 13 inserted through the projection 12. At the same time, the lower end of the cover 5 is also pivotally supported by the hinge shaft 13.

The structure of this pivot portion will be explained with reference to FIGS. 3 and 4. The lower part of the cover 5 includes the first,
As shown in FIG. 2, there is a horizontal portion 5A along the top surface of the Western-style toilet bowl 1, and the front end side of the horizontal portion 5A (front end side of the Western-style toilet bowl 1) is for receiving the arm portion 14a on the toilet seat 14. A recess 5B is provided. The protrusion 12 extends 1 in the width direction of the Western-style toilet bowl 1.
A pair of hinge shaft insertion holes are provided in the width direction of the Western-style toilet bowl 1. The hinge shaft 13
The cover 5 and the arm portion 14a pass through the hinge shaft insertion hole in the width direction of the Western-style toilet bowl 1, and the cover 5 and the toilet seat 14 are pivotally supported on the Western-style toilet bowl 1.

As shown in FIG. 4, the hinge shaft 13 includes a main body portion 13b having a flange portion 13a at one end, and a bolt portion 13d screwed into a screw hole 13c drilled in the other end surface of the main body portion 13b. Main body part 1
3b to the cover 5, the arm part 14a and the protrusion 1
2 through the screw hole 13c.
By screwing the cover 5 into the toilet seat 14, the pivot between the cover 5 and the toilet seat 14 is completed. Note that enlarged recesses 5c are provided on both side surfaces of the cover 5 for locking the flange portion 13a and the bolt portion 13d.

In FIG. 2, reference numeral 15 is a rim water passage provided around the upper edge of the toilet bowl 2, and flush water is supplied through the water passage 16 and opening 17. A water passage 18 branches from the middle of the water passage 16,
The toilet bowl 2 is configured to forcibly cause a siphon action by ejecting water from a spout hole (not shown) to discharge waste from the toilet bowl 2. Reference numeral 19 indicates a drain port.

Note that a water supply pipe may be connected to the opening 17,
Alternatively, a low tank may be installed in the rising portion 3 and the outlet of the low tank may be directly connected to the opening 17.

In the Western-style toilet bowl configured in this way, when a human body leaves the Western-style toilet bowl 1, the human body detection sensor 9
When this departure is detected, flushing water is supplied into the toilet bowl 2. It should be noted that a configuration may be adopted in which a small amount of flushing water is flushed when a human body approaches or sits on the Western-style toilet bowl 1.

Therefore, in this Western-style toilet bowl 1, the human body detection sensor 9 is provided integrally with the Western-style toilet bowl 1, and there is no need for wiring work to connect the sensor 9 and the control device 10.
