[0005]

When the toilet bowl is equipped with a low tank as in the above-mentioned conventional technique,
It is possible to supply the wash water from the low tank to the excrement measuring device, but in the case of a toilet bowl (flush valve method) that uses the direct pressure of the water supply source to transfer waste from the toilet bowl, there is no low tank, so Cannot be supplied to the excrement measuring device. Therefore, the flush valve type toilet bowl has a problem that the excrement measuring device cannot be attached. In addition, even if there is a low tank, if the water used is not sterilized like tap water instead of tap water, bacteria such as mold will propagate in the measurement path and the path will be blocked. It may be impossible.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a flush valve type toilet and a toilet equipped with a low tank type toilet using water in water. An object of the present invention is to provide a wash water supply method for an excrement measuring device, which can supply water suitable for washing to the excrement measuring device.

[0007]

[Means for Solving the Problem and Its Action / Effect] In order to achieve the above-mentioned object, claim 1 provides an excrement measuring device from a water supply source through a water supply pipe and a water storage tank provided in the middle of the water supply pipe. A flush water supply method for an excrement measuring device that supplies water, wherein the water storage tank detects a water inlet portion, a solenoid valve provided in the water inlet portion, a water reservoir portion, and a water storage amount of the water reservoir portion. A water storage amount detection means and a water discharge portion are provided, and after starting water discharge from the water discharge portion based on a water supply start command from the excrement measurement device, based on the detection of a decrease in the water storage amount by the water storage amount detection means. Then, the solenoid valve is opened to start water supply from the water inlet to the water reservoir. Therefore, even in a toilet equipped with a flush valve type toilet bowl, wash water can be supplied from the water storage tank based on a water supply start command from the excrement measurement device. Further, even in a toilet equipped with a low tank type toilet bowl using medium water or the like, water suitable for cleaning can be supplied to the excrement measuring device from a water storage tank provided separately from the low tank.

According to a second aspect of the present invention, in the wash water supply method for the excrement measuring apparatus according to the first aspect, the amount of water supplied from the water inlet to the water reservoir per unit time is calculated as the water outlet per unit time. It was less than the amount of water discharged from. Therefore, the chattering phenomenon in which the solenoid valve opens and closes many times during water supply does not occur, and it is possible to suppress the generation of abnormal noise and noise.

According to a third aspect of the present invention, in the flush water supply method for an excrement measuring apparatus according to the first aspect, the water supplied from the water inlet to the water reservoir is detected by the water storage amount detecting means. Then, after a predetermined on-delay time has elapsed, the process is started and the on-delay time is made variable. Therefore, even if the water supply pressure fluctuates, the amount of water supplied from the water inlet to the water reservoir can be made smaller than the amount of water discharged from the water outlet, which causes the chattering phenomenon in which the solenoid valve repeatedly opens and closes during water supply. It is possible to suppress the generation of abnormal noise and noise.

According to a fourth aspect of the present invention, in the flush water supply method for an excrement measuring device according to any one of the first to third aspects, the water outlet from the water outlet is stopped based on a water supply stop command from the excrement measuring device. After that, the electromagnetic valve is closed based on the detection of the predetermined water storage amount by the water storage amount detection means, and the water supply from the water inlet to the water reservoir is stopped. Therefore, since the water storage unit always holds a fixed amount of water, it is possible to immediately supply the wash water if there is a water supply start command from the excrement measurement device.

According to a fifth aspect of the present invention, in the flush water supply method for the excrement measuring device according to the fourth aspect, after stopping the water from the water outlet based on a water supply stop command from the excrement measuring device, When the stored water amount detecting means does not detect the predetermined stored water amount even after a lapse of a certain time, the electromagnetic valve is closed and the water supply from the water inlet to the water reservoir is stopped. For example, when an abnormality such as water leakage from the water storage unit occurs, it is assumed that after the water supply from the water supply unit is stopped, the predetermined amount of stored water cannot be detected and the water supply from the water supply unit continues. Leakage may spread if left in this state,
Since the water supply is stopped by closing the solenoid valve after a certain time has passed after the stoppage of water from the water outlet, it is possible to prevent the spread of water leakage damage.

According to a sixth aspect of the present invention, in the wash water supply method for an excrement measuring device according to the first to fifth aspects, the solenoid valve is driven by a battery. Therefore, it is not necessary to consider whether there is a power outlet provided in the toilet or how to route the power cord.

According to a seventh aspect of the present invention, in the flush water supply method for an excrement measuring apparatus according to the first to sixth aspects, the water storage tank is provided with a mounting portion to a wall surface. If the water storage tank is attached to the wall surface, it is easier to clean the floor of the toilet than when the floor is installed.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a view showing a toilet equipped with an excrement measuring apparatus according to an embodiment of the present invention. In FIG. 1, 106 is a flush valve, which conveys waste from the toilet bowl 101 using the direct pressure of the water supply source (flush valve system).

As shown in FIG. 1, a urine collecting section 12 is mounted on the rim of a toilet bowl 101 installed in a toilet, and a urine collecting arm 13 of the urine collecting section 12 rotates in a bowl of the toilet bowl 101. Collect the user's urine. The collected urine is sent to the main body 11 through the pipe 15 and the components are analyzed. As described above, the excrement measurement device 10 includes the urine collection unit 12
And a main body 11. A toilet seat 102 and a toilet lid 104 are openably and closably attached to the toilet bowl 101 (open state in FIG. 1).

A member such as the urine collecting arm 13 of the excrement measuring device 10 that comes into contact with urine and a measurement system path that comes into contact with urine (not shown) must be washed with water to maintain the function. In the present embodiment, this water is supplied from the wash water supply device 20 to the excrement measurement device 10 via the water absorption pipe 23. Hereinafter, the method of supplying the cleaning water will be described.

The water taken out from the branch fitting 107 of the flush valve 106, which is the water supply source, is supplied to the water storage tank 22 of the cleaning water supply device 20 via the water supply pipe 21.
The supplied water is transferred from the water storage tank 22 to the excrement measuring device 10 via the water absorption pipe 23 when a water supply command is issued from the excrement measuring device 10 by operating a pump (not shown) inside the excrement measuring device 10. Supplied. As described above, by providing the flush water supply device 20, flush water can be supplied to the excrement measuring device even in a toilet equipped with a flush valve type toilet bowl. If the water supplied from the flash valve 106 is not sterilized such as tap water instead of tap water, bacteria such as mold will propagate in the measurement path of the excrement measuring device 10 and the path of the path will be reduced. May be blocked and measurement may not be possible. In this case, as shown by the broken line in FIG. 1, water may be taken from the water stop valve 108 connected to clean water and supplied to the water storage tank 22.

FIG. 2 is a system block diagram showing the water channel system of FIG. 1, and FIG. 3 is a sectional view of the wash water supply device 20. As shown in FIG. 2, a branch metal fitting 107 (or a water stopper 108) of the flush valve 106 which is a water supply source.
The water taken out from is supplied to the water supply pipe 21 through a strainer 31 for removing foreign matter in the water and an orifice 32 having a small hole for obtaining an appropriate amount of water. The water supply pipe 21 is connected to the opening / closing valve 25 of the wash water supply device 20, and the water passage is opened / closed by an electromagnetic valve 26 driven by an instruction from the controller 27. Since the controller 27, the electromagnetic valve 26, and the like are driven by the battery 34, it is not necessary to consider the presence or absence of a power outlet provided in the toilet and the method of routing the power cord.

The water discharged from the opening / closing valve 25 is supplied to the water storage tank 22 through the concave stitch member 33. The concave stitch member 33 is made of a mesh of # 50 to 200 size and has a radius of 1/2 of the discharge port diameter.
As shown in FIG. 3, since a space is provided between the discharge port and the water storage tank 22, sewage will never flow back to the clean water side. The water supplied to the water storage tank 22 is stored in a predetermined amount under the supervision of the water amount detection member 28. In addition,
When the water passes through the concave stitch member 33, the water is rectified and the water surface is prevented from undulating, so that unnecessary chattering of the water amount detecting member 28 is prevented.

When there is a water supply command from the excrement measuring device 10 due to the operation of a pump (not shown) inside the excrement measuring device 10, water is taken from the water storage tank 22 into the water intake unit 2
9 and is supplied to the excrement measuring device 10 via the water absorption pipe 23. Then, the shortage is supplied again from the water supply source. After that, the water supply to the excrement measuring device 10 is stopped by the water supply stop command from the excrement measuring device 10, and when the water amount detection member 28 detects a predetermined amount of stored water, the water supply from the water supply source to the water storage tank 22 is also stopped. In this way, since the water storage tank 22 always holds a fixed amount of water, if there is a water supply start command from the excrement measurement device 10, the wash water can be immediately supplied.

If a problem occurs such that the water supply to the water storage tank 22 does not stop, the water is discharged to the toilet bowl 101 through the overflow pipe 24, so that water leakage to the floor is prevented. To be done. In addition, in order to prevent the generation of mold, algae, bacteria, etc. in water, a structure capable of supplying antibacterial ions such as silver ions and iodine ions and bacteriostatic agents such as sodium azide to the water storage tank 22 is added. Good.

In this embodiment, the amount of water supplied from the open / close valve 25 to the water storage tank 22 per unit time is smaller than the amount of water output from the water storage tank 22 to the excrement measuring device 10 per unit time (water supply). Amount <water discharge amount). For this reason,
It is possible to suppress the occurrence of abnormal noise and noise without causing the chattering phenomenon in which the solenoid valve 26 is repeatedly opened and closed during water supply. In addition, in order to obtain the same effect, the water storage tank 2
2 to the excrement measuring device 10 and water amount detecting member 28
When the decrease in the amount of stored water is detected, the supply of water from the opening / closing valve 25 to the water storage tank 22 may be started after a predetermined on-delay time. The method of setting the on-delay time will be described below.

FIG. 4 shows a solenoid valve 2 connected to the opening / closing valve 25.
6 is a flowchart for setting an on-delay time of 6. The solenoid valve 26 is first set with a predetermined on-delay time. When the water amount detecting member 28 detects the decrease in the stored water amount, the timer is started. Then, after waiting the above-mentioned on-delay time, the solenoid valve 26 is opened, and water is supplied to the water storage tank 22. Then, when the water amount detecting member 28 detects that the predetermined amount of water has been stored, the electromagnetic valve 26 is closed and the supply of water is stopped. If a predetermined amount of water does not accumulate after the timer starts, it is determined that water may leak from the water storage tank 22, and the electromagnetic valve 26 is closed to stop the water supply. This can prevent the spread of water leakage damage. The timer may be started when the water discharge from the water storage tank 22 to the excrement measuring device 10 is stopped.

Even if the predetermined amount of water is stored, if the water is stored in a shorter time than the predetermined time, the excrement measuring device 1
Water tank 22 rather than the amount of water per unit time to 0
It is possible that the amount of water supply to the In this case, water supply and stoppage may occur repeatedly in a short time, so the on-delay time will be extended from the next time. In this way, the on-delay time can be changed depending on the situation, so that the chattering phenomenon can be prevented even when the water supply pressure changes, for example.

FIG. 5 is a view showing a mounting state of the cleaning water supply device 20. As shown in FIG. 5, the water storage tank 22
The flush water supply device 20 including the above is fixed to the wall surface of the toilet via the attachment stay 30. The flush water supply device 20 may be installed on the floor of the toilet, but when fixed to the wall,
It does not get in the way when cleaning the floor of the toilet, so it is easy to clean. If the design of the flush water supply device 20 does not match the design of the entire toilet, a cover that covers the entire flush water supply device 20 may be provided to ensure the total design of the toilet.

FIG. 6 is a view showing a toilet equipped with an excrement measuring device according to another embodiment of the present invention. In FIG. 6, a low tank 105 is used to store the water supplied from the stop cock 108 and to discharge the excrement in the toilet 101 to the sewage. When the water supplied to the low tank 105 is clean water, the low tank 1
There is no problem even if the cleaning water is supplied to the excrement measuring device 10 from 05. However, if the water supplied to the low tank 105 is not sterilized like medium water, various bacteria such as mold may propagate in the measurement system path and block the system path, which may make measurement impossible. Therefore, in the present embodiment, the water stopcock 1
