Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a toilet bowl that uses flush water to clean the private parts of the body after defecating.

Conventional structure and its problems Washing toilet bowls are intended for cleaning the anal area after defecating, and for cleaning the female private parts during menstruation during urination, but the anal area and female private parts are kept at an appropriate temperature. There has been a problem in that only one of the anus and female private parts can be washed at a comfortable temperature because the washing water temperature is different.

The configuration of a conventional example is shown in FIG. 1 is the toilet seat, 2 is the tank,
Reference numeral 3 denotes a pump motor which causes hot water in the tank 2 to be spouted from a nozzle 4 through a hose 5. 6 is a hose connecting the pump motor 3 and the tank 2. Figure 2 shows a system configuration diagram. Components that are the same as those in FIG. 1 are given the same numbers. 8 is a cistern that stores water in the flush tank, 9 is a hose that connects the cistern 8 and the pump motor 3, and 10 is a tank 2
A sensor that detects the temperature of the cleaning water inside, and in this example it is a thermistor. 11 is a heater that heats the cleaning water in the tank 2; 12 is a heater 11 that is heated by a signal from the thermistor 10;
This is a control section that controls the supply of electricity to the tank 2 and keeps the temperature inside the tank 2 constant.

FIG. 3 is an example of a circuit diagram of a conventional flush water temperature control circuit for a toilet bowl. In the figure, the same parts as in FIGS. 1 and 2 are given the same numbers. Electrolytic capacitor 13. resistance 14
．． The diode 16 constitutes a DC power supply for the control section 12. 16 is a volume for temperature setting, 17 to 2o are resistors, 21 is a comparator (open collector type controller), and 22 is a gate that controls a bidirectional thyristor 23 that turns on and off the current to the heater 11. This is a current switching transistor.Volume 16 and resistor 1
Voltage Va at the connection point with 7, thermistor 10 and resistor 1
The voltage vb at the connection point with 8 is input to the comparator 21, and Va>
At the time of vbQ, the output of the comparator 21 becomes Hi, the transistor 22 is turned on, and the thyristor 23 is turned on. On the contrary, V
a < V t), the output of the comparator 21 becomes Lo, the transistor 22 is turned off, and the thyristor 23 is also turned off □ When Va is constant, Va>vb means that the resistance of thermistor 1o is Va This means that the resistance is smaller than the resistance when = V b, and Va (V b means, conversely, that it is smaller than the resistance when Va = V b. 0 Thus, when the temperature of the thermistor 1° is low, the heater 11
The temperature of the cleaning water in the tank 2 is controlled by energizing it and turning it off when the temperature is high. However, the temperature of the washing water that is considered appropriate for the female private parts and the anal area is different (and in general, the temperature of the washing water that is considered to be the appropriate temperature is [the temperature that is felt to be the appropriate temperature for the anal area]) [the temperature that is felt to be the appropriate temperature for the female private parts] ) Despite this, I try to adjust the temperature with volume 16 in order to use wash water at an appropriate temperature for both the anus wash and the female private parts wash, but the wash water in tank 2 does not respond quickly. . In particular, even if you lower the set temperature, you just have to wait for it to cool down naturally, which takes a very long time. In other words, if the temperature is set to a temperature that feels appropriate for the anal area, even if you change the setting to the appropriate temperature for washing female private parts when using water for washing female private parts, it will take a very long time for the water temperature to drop. Because of this, it feels hot when you use it. On the other hand, you can always set the temperature to the optimum temperature for cleaning the female private parts and raise the temperature setting only when cleaning the anus, but you have to change the temperature setting each time you clean the anus. After cleaning the anal area, the temperature setting must be changed again to a temperature suitable for cleaning the female private parts. These series of operations are very tedious and often forgotten. As described above, conventional toilet bowls have been extremely difficult to use.

OBJECTS OF THE INVENTION The present invention aims to eliminate such conventional problems and to improve usability by automatically changing the set temperature of the washing water.

Structure of the Invention In order to achieve this object, the present invention is configured such that the control section detects whether a person is sitting and changes the set temperature. With this configuration, it is possible to automatically change the temperature of the washing water when washing the anus and when washing the female private parts. Description of Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a circuit diagram of a flush water temperature control circuit in an embodiment of the flush toilet of the present invention. Components that are the same as those in FIGS. 1 to 3 are designated by the same numbers. 24 is a resistor, and 25 is a human body detection section, which in this example is a microswitch provided on the first part of the toilet seat. If the microswitch 26 is connected to the A side when the seat is not seated, and to the B side when the seat is seated, Va will be (Va when the seat is not seated) < (Va when the seat is seated), and the temperature of the cleaning water will be the same when the seat is seated. time rises. FIG. 5 shows the relationship between cleaning water temperature and time when the toilet bowl of the present invention is not seated and when the toilet bowl is seated. T
1 is a set temperature slightly lower than the appropriate temperature of the washing water for washing a woman's private parts, and T2 is a set temperature that is comfortable for washing the anus. FIG. 6 shows the relationship between washing water temperature and time when a woman uses the water only for washing her private parts. In this case, the time from sitting to using the washing water is short. If this time is Δt1, Δ
The temperature increase after t1 is Δt1, which is very close to the comfortable temperature of the washing water for women's private parts. Furthermore, if wash water is used, the wash water with a low temperature is supplied from the distern 8 into the tank 2, so the temperature of the wash water does not rise, and a comfortable wash water temperature can be continuously obtained.

Next, when it is used to clean the anus, it becomes as shown in Fig. 7. When cleaning the anus, the time Δt2 from sitting down to the start of using the cleaning water is longer than Δt1.

Therefore, the temperature is suitable for cleaning the anus at the time when cleaning the anus starts. Further, when a woman washes her private parts after washing her anus, the amount of washing water used for washing her anus is large, so the temperature of the washing water decreases and becomes close to the temperature suitable for washing her private parts.

Further, FIG. 8 shows the configuration of an embodiment of the human body detection section. 1st
Components with the same numbers as those in FIGS. to 4 are the same. 27
is a lever of a microswitch 25, and 28 is a human body.

Reference numeral 26 denotes a convex object fixed to the toilet seat 7, and when a human body 28 is seated on the toilet seat, the toilet seat 7 itself is lowered and the lever 27 is lowered via the convex object 26 to switch the micro switch 25.

Effects of the Invention As is clear from the above description, the flushing toilet of the present invention includes a flushing part that discharges flushing water to the toilet seat and private parts of the human body, a tank that stores the flushing water, and a heater that heats the flushing water in the tank. , a sensor that detects the temperature of the cleaning water in the tank, and a control unit that controls energization of the heater based on a signal from the sensor to control the temperature of the cleaning water, and the control unit detects when a person is seated. Since the temperature of the washing water can be changed by changing the temperature of the washing water, it is possible to always perform very comfortable washing regardless of the area to be washed.

Furthermore, since the present invention makes full use of the actual usage of the toilet seat, it is extremely valuable in that only a few additional parts are required compared to conventional circuits.
