Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a warm water-washing toilet seat that cleans the private parts of toilets with warm water.

Structure of conventional example and its problems It is well known that hot water is conventionally used to wash private parts after using the toilet in order to prevent discomfort. In this case, the temperature of the hot water is preset, and during cleaning, the user operates a temperature control knob or the like provided on the toilet seat to adjust the temperature to a desired temperature. That is, in order to obtain the final comfortable hot water temperature, the user had to adjust the temperature himself/herself.

On the other hand, the water temperature at which comfort is felt depends on the skin temperature, and the skin temperature also differs depending on the individual user or the room temperature. Therefore, even if the temperature of the hot water is set in advance, it may be pleasant or unpleasant depending on the user or the room temperature. In particular, the hot water temperature cannot be adjusted to a comfortable level until it is first applied to the private parts, which has the disadvantage of having to endure discomfort such as the feeling of cold water when starting to wash.

OBJECTS OF THE INVENTION In order to eliminate the above-mentioned drawbacks, the present invention aims to automatically adjust the water temperature according to the skin temperature of the user.

Structure of the Invention To achieve this object, the present invention includes a temperature sensor to detect the skin temperature around the local area during urination;
The temperature of the cleaning water is automatically adjusted based on this detected temperature.

With the above configuration, the skin temperature is detected during urination and the hot water temperature is adjusted accordingly.
Warm water adjusted to an appropriate temperature can be used from the start of cleaning.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIG. As shown in FIG. 1, the present invention includes an electric heater 5 for heating hot water connected to a power source 4 in a hot water tank 3 for supplying hot water to a local area from a nozzle 2 via a pump 1, and a hot water tank 3. A hot water temperature detector 6 is disposed to detect the temperature of the water inside, and the power supply section 4 is connected to a control section 7 that controls the output voltage to the electric heater 5. Further, an infrared temperature sensor 8 for detecting the user's skin temperature and the hot water temperature detector 6 are connected to the control unit 7, and the control unit 7 Accordingly, the output voltage of the power supply unit 4 to the electric heater 5 is automatically controlled.

On the other hand, in the power supply unit 4, a sub-control unit 9 that can manually adjust the output voltage from the power supply unit 4 is connected to the power supply unit 4 while disconnecting the infrared temperature sensor 8 and the control unit 7. A circuit switch 10 is provided as shown in FIG. In FIG. 1, reference numeral 11 indicates a power supply for supplying power to the power supply section 4, and reference numerals 12 and 13 indicate water supply pipes and hot water pipes for supplying water to the hot water tank 3 and hot water to the nozzle 2. Further, solid line arrows indicate the flow of water supply and hot water.

Next, the effect of this configuration will be described. The circuit switch 10 is set to connect the infrared temperature sensor 8 and the control unit 7.The infrared temperature sensor 8 detects the user's skin temperature while the user is using the toilet, and the temperature is adjusted to the detected temperature. Accordingly, the control unit 7 automatically determines a water temperature that feels comfortable, and controls the electric heater from the power supply unit 4 so that there is no difference between the hot water temperature and the hot water temperature detected by the hot water temperature detector 6 in the hot water tank 3. Controls the output voltage to 5. Therefore, after using the toilet,
At the time of washing the private parts, the temperature of the hot water is automatically adjusted so that the user feels comfortable.

On the other hand, by cutting off the connection between the infrared sensor 8 and the control section 7 using the circuit switch 10 and simultaneously connecting the power supply section 4 and the sub-control section 9, it is possible to manually adjust the temperature.

Effects of the Invention According to the present invention, a temperature sensor detects the skin temperature around the private part during defecation, and automatically controls the water temperature so that the water temperature corresponds to the skin temperature and feels comfortable. You can get a comfortable water temperature from the start. Therefore, it is possible to provide a cleaning device that does not cause discomfort such as the sensation of cold water during cleaning.
