Abstract

PURPOSE:To measure accurately a urine temperature by always outputting a temperature signal of a bowl section by a temperature sensor provided to a part to the bowl section to which urination hits and outputting a urine temper ature based on a variation between the signal and an output signal in case of a urination. CONSTITUTION:A memory 12 memorizes periodically a temperature signal of a temperature sensor 11 mounted to a bowl section of a stool. After that, the temperature signal TO to be memorized is continuously compared with the present temperature signal by means of a comparator 13. Then, in case a urination is made, a urination decision 14 decides that there is a urination by increasement of the temperature signal 13 from the sensor 11, and a tempera ture gradient calculation means 15 is operated. The calculation means 15 calculates a temperature rise gradient T, and it is outputted together with the temperature signal TO to a urine temperature output means 16. Furthermore, the output means 16 outputs the urine temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a toilet bowl for measuring urine temperature, which uses a sensor to measure urine temperature.

(Prior Art) A urine temperature measuring toilet is known in which a temperature sensor is provided on a portion of the bowl surface of the toilet that is hit by urine, and the urine temperature is detected based on the output signal of this sensor.

In such a toilet bowl, the temperature detected by the sensor is the temperature of the sensor itself.

(Problem to be solved by the invention) Therefore, when urine hits the sensor, the sensor cannot detect the internal temperature, and the detected temperature depends on the heat capacity of the sensor itself and the surface of the ball to which the sensor is attached. temperature,
The temperature gradually approaches the urine temperature along a predetermined curve determined by the thermal conductivity between the sensor and the toilet bowl, and there is a delay in the detected temperature for urination.

Therefore, if urination ends before the sensor reaches the urine temperature, an error will occur in the measured temperature due to this delay.

Therefore, the present invention has been made to solve such conventional problems, and its purpose is to provide a urine temperature measuring toilet that can accurately measure urine temperature despite the delay in temperature detection.

(Means for Solving the Problem) In order to solve the above-mentioned problem, the present invention provides a temperature sensor 11 in the portion 9b of the bowl surface of the toilet bowl 1 that is hit by urine, and based on the output signal of the temperature sensor 11. In the urine temperature measuring toilet 1, the sensor 11 constantly outputs the temperature signal of the pole surface 9, and the urine temperature is measured based on the output signal and the change in the output signal when urination occurs. The concentration will now be output.

(Function) According to such a configuration, the urine concentration can be obtained even if the sensor does not reach the urine concentration.

(Example) Examples of the present invention will be described below with reference to the accompanying drawings, taking a urine test toilet as an example.

FIG. 1 is a perspective view showing a urine test toilet according to an embodiment of the present invention, FIG. 2 is a plan view of the same toilet, FIG. 3 is a block diagram showing a temperature measuring section, and FIG. 4 is a diagram showing another embodiment. It is.

A toilet seat 2 and a toilet lid 3 are provided on the front upper surface of the toilet bowl 1, an operating section 4 is provided on the negative side, and a modem 7 equipped with a blood pressure monitor 5 and a display means 6 is provided on the other side. A box section 8 containing a cleaning tank, a urinalysis device, a urine temperature measurement section, etc. is provided at the rear.

A part of the inside of the pole 9 of the toilet bowl 1 is a rearward bulge 9a, and a deep part 10 is formed near the bottom of the bulge 9a.
is formed. The upper surface of this deep urination part 10 is continuous with the ball surface 9 of the toilet bowl 1 so that a part of the urine surely flows into the urination part lo, and the part 9 of the ball surface 9 that is hit by urine.
A urinary channel 9C whose height gradually decreases from b toward the deep part 10 is formed by recessing a part of the ball surface 9. A temperature sensor 11 for detecting the temperature of urine is provided in the portion 9b of the toilet bowl 1 that is hit by the urine.

For example, a thermistor or the like is used as the temperature sensor 11.
The temperature signal, which is the output signal, is processed by the configuration shown in FIG. 3 and displayed on the display means 6 as urine concentration.

Urine temperature measurement will be described below with reference to FIG. 3.

Since the temperature sensor 11 is attached to the ball surface 9, the temperature is approximately equal to the temperature of the ball surface during normal times (when the toilet is not in use). The memory 12 periodically stores the temperature signal output by the temperature sensor 11, and the stored temperature signal To is constantly compared with the current temperature signal by the comparator 13.

Therefore, according to this configuration, when urination occurs, the output signal of the temperature sensor 11 increases rapidly, and as a result, the output signal of the comparator 13 also increases rapidly, and therefore, urination is determined based on the increase in this output signal. Means 14 may determine that there has been urination. When urination is determined, the urination determining means 14 operates the temperature gradient calculating means 15, and the temperature gradient calculating means 15 calculates the gradient ΔT of the temperature rise of the sensor 11. This temperature gradient ΔT is the stored temperature signal T
O1, that is, the temperature of the ball surface 9 as well as the next urine temperature output means 16
is output to. This urine temperature output means 16 outputs T to the temperature gradient.
It is equipped with a memory that stores urine concentration data as a table with the temperature TO of the ball surface as a parameter (address), and the urine concentration data can be retrieved using the calculated temperature gradient ΔT and the temperature TO of the ball surface. Output the concentration.

Thus, according to this embodiment, when measuring urine temperature, urination can also be automatically detected, which is extremely convenient without requiring any operation (for example, switch operation) for measuring urine temperature. It is.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments. For example, the urine temperature output means may directly calculate the urine concentration from the temperature gradient and the temperature of the ball surface. In addition, in this embodiment, urination can be detected automatically, but the configuration can be easily configured, for example, by starting urine temperature measurement by the user's switch operation, as shown in Fig. 4. Become.

(Effects of the Invention) As is clear from the above description, according to the present invention, it is possible to provide a urine temperature measuring toilet that can quickly obtain accurate urine concentration regardless of the delay in the temperature detected by the temperature sensor. .

Furthermore, according to this embodiment, urination can also be automatically detected using a temperature sensor for detecting urine concentration.
Extremely convenient.
