Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to an improvement of a toilet bowl equipped with a urinalysis sensor.

[Conventional technology]

Conventionally, toilets equipped with urine sensors have
There is something related to No. 60-156188 (Utility Model Application No. 62-75468). That is, as shown in FIGS. 6 and 7, the toilet bowl 1 includes a partition wall 4 that connects the inside of a rim passageway 3 formed around the opening of the toilet bowl body 2 in the direction in which the waterway travels.
Inner toilet bowl cleaning channel 5 and outer reagent channel 6
An extended reagent passage 7 (see FIG. 6) extending from the reagent passage 6 is formed on the outer surface 2a of the toilet main body 2, and a discharge hole 7a of the extended reagent passage 7 is
It opens directly above the bowl surface of the urine detection sensor 8 provided in the urine retention section 2c inside the toilet main body 2.

[Problem that the invention attempts to solve]

However, in conventional toilet bowls, the interior of the rim passageway 3 is divided by the partition wall 4 to form the two waterways 5 and 6, but the manufacturing process is several times that of a single rim passageway. The problem was that the cost was high.

[Means to solve the problem]

The gist of the present invention, which was created to solve the above problems, is to form a rim passageway for flushing water at a suitable location around the opening of the toilet body, and to install a urine detection sensor in the urine retention area of the toilet body. In a toilet bowl equipped with a reagent passage for supplying urine test reagent from a reagent supply device to a urine test sensor, the reagent passage is formed by a reagent supply pipe inserted into the rim water passage, and the downstream end of the reagent supply pipe has a A reagent spouting section is provided that faces into the toilet bowl body and directs the jetting direction toward the urine-retaining section.

[Effect]

The reagent supplied from the reagent supply device flows through the reagent supply pipe in the rim water passage and is injected from the reagent injection section to the urine retention section provided with the urine detection sensor.

[Explanation of Examples]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a toilet bowl equipped with a urinalysis sensor according to the present invention will be explained based on the embodiments shown in FIGS. 1 to 5. The toilet main body 12 is made of ceramic, stainless steel, synthetic resin, or the like, and has a rim passageway 13 for flushing water formed around the opening. The rim water passage 13 has cleaning water discharge ports 14, 1 on the bottom wall 13a.
4... are bored at appropriate circumferential pitches, and a pipe outlet hole 15 is provided near the front center of the bottom wall 13a.
(See Figures 1 and 5) are drilled. The toilet main body 12 is provided with a urine detection sensor 8 whose detection portion is exposed in the urine retention portion 12c. The urinalysis sensor 8 may be of any suitable type, such as a H ₂ O ₂ electrode or an O ₂ electrode. The output lead wire 8a of the urinalysis sensor 8 is guided to a display device (not shown) installed on the side of the toilet bowl body 12 or the like. A reagent supply pipe 17 is inserted into the rim passageway 13 . The upstream side 17a of the reagent supply pipe 17 is connected to the toilet main body opening 1.
2a to the outside of the toilet main body, and is connected to the entrance end 17b.
(see FIG. 3) is connected to the pump outlet 18a of the reagent supply device 18. The reagent supply tube 17 is
The downstream side 17c (see FIG. 5) is the pipe outlet hole 15.
It extends into the toilet main body 12 via a support 19 fitted to the tube, and the urine retention section 1 is provided at the tip of the tube.
2c (Reagent spouting section 20 with the jetting direction shown in Figure 3)
is provided. A cleaning water supply pipe 21 is provided in the rim water passage 13.
are inserted as necessary. Cleaning water supply pipe 21
is the rim passageway 1 through which the reagent supply pipe 17 is inserted;
3, the reagent supply pipe 17 is inserted in parallel with the reagent supply pipe 17 on the passage A side, or the passage A
It is inserted into the passage B side opposite to the side. The upstream side 21a of the flush water supply pipe 21 is connected to the toilet main body opening 12a.
The inlet end 21b (see FIG. 3) is connected to a water intake valve 22 made of a solenoid valve, a flush valve, or the like. The downstream side of the flushing water supply pipe 21 extends into the toilet main body 12 via a support 19 fitted into the pipe outlet hole 15, and a water supply pipe is provided at the tip of the pipe with a jet direction directed toward the urine detection sensor 8. A cleaning water injection section 23 (see FIG. 3) is provided. In addition, when inserting the reagent supply pipe 17 and the washing water supply pipe 21 in parallel in the rim passageway 13, as shown in FIG. 21 are joined at appropriate pitches, and both pipes 17, 21 are connected to pipe supports 24, 2.
It is preferable to secure the wash water passage C below both the pipes 17, 21 by supporting them with the leg parts 24a, 24a of the pipes 17, 21. The procedure for inserting both the pipes 17, 21 into the rim water passage 13 using the pipe supports 24, 24... is to insert both the pipes 17, 21 outside the toilet main body 12.
21 at appropriate pitches with pipe supports 24, 24..., and then insert both pipes 17, 21 into the rim water passage 13 from the opening 12a of the toilet main body 12.
4... and insert it together with the downstream side 1 of both pipes 17 and 24.
7c, 21c to the outside from the pipe outlet hole 15 of the toilet main body 12, connect the reagent spouting part 20 and the cleaning water spouting part 23 attached to the support 19 to the corresponding pipes, and finally remove the support 19. This is done by fitting it into the lead-out hole 15. It is preferable that the reagent spouting part 20 and the washing water spouting part 23 be installed in a state where the toilet user cannot see them during normal use. Next, the behavior of the reagent and washing water will be explained based on this example. The urine urinated in the toilet main body 12 is
The urine is automatically guided to the urine retention section 12c, and the urine sample sensor 8
come into contact with. A reagent (for example, an enzyme reagent consisting of glucose oxidase and a buffer solution) supplied from the reagent supply device 18 flows through the reagent supply pipe 17 and is injected from the reagent injection section 20 to the urine retention section 12c.
When the reagent is added to the urine in the urine retention section 12c, the urine test sensor 8 emits a detection signal. When this signal is led to a display section (not shown) by the output lead wire 8a, the display section performs analysis processing and displays the test results.
When the inspection is completed, cleaning water is supplied to each of the rim passageway 13 and the cleaning water supply pipe 21, and the cleaning water discharge ports 14 and 1 provided at the bottom of the rim passageway 13 are supplied with cleaning water.
4. Washing water is discharged into the toilet bowl from ......, and
Cleaning water spout section 2 provided at the tip of the cleaning water supply pipe 21
Cleaning water is sprayed from 3 toward the urine test sensor 8.

[Effects of this invention]

As detailed above, the toilet equipped with the urinalysis sensor according to the present invention allows the rim passageway formed in the toilet body to be a single waterway, so the inside of the conventional rim passageway can be replaced with a partition wall. This has the practical effect of dramatically reducing manufacturing man-hours compared to toilets that are partitioned to form two waterways.
