Reference numeral 9 denotes a storage box that houses a pump for supplying water in the distiller 4 to the cleaning nozzle 6, a fan for producing the drying air 8, a motor, a heater, and the like.

In the configuration shown in FIG. 1, the cleaning water is discharged from the cleaning nozzle 6 to the part to be cleaned of the human body 3, as shown by the dotted line,
Thereafter, the drying air 8 is blown out to dry the wet area of the cleaning section. However, in the conventional configuration shown in FIG. If you stop the drying operation before the drying is finished, the moment you stand up from the toilet seat 2, the remaining water will run down your legs and cause you discomfort, and as mentioned above, the remaining water will flow down your legs until it stops flowing. However, when wearing underwear, it gets caught on damp skin, and there is a feeling of residual moisture after putting on underwear, which is extremely unpleasant. Contrary to the above, if you blow drying air for a long time without noticing the end of drying, there is a risk of low-temperature burns.
Even if it does not reach that point, it still has the disadvantage that the skin becomes too dry and the surface becomes flaky.

The present invention solves the above-mentioned drawbacks of the conventional method by adding a function of automatically confirming completion of drying and stopping drying.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

Reference numeral 14 denotes a drying function that includes a fan motor, a heater, etc. that generate drying air. 16 is a power source, 16, 17° 18 is a resistor, and the pair of electrodes 11
．． A bridge is formed by the 12 resistors. 19 is an open collector type comparator that compares the midpoint potential of the bridge, 20 is a resistor, and 21 is a transistor.

In the circuit configuration shown in FIG. 3 above, when the cleaning part of the human body and its circuit are wetted by the cleaning water, the resistance on the surface of the human body decreases, and as a result, the pair of electrodes 11, 12 on the human body contact surface 1o The resistance between them will be a -small value. Therefore, the single voltage potential of the comparator 19 falls below the input voltage potential, and the output of the comparator 19 is turned off.Therefore, the transistor 21 is turned on. When the drying switch 13 is turned on for this purpose, the drying function 14 is energized to blow out the drying air 8 and start drying.As the drying progresses, the resistance between the pair of electrodes 11 and 12 increases. Therefore, the electric potential of the comparator 19 also rises.Then, at the end of drying, the electric potential of the comparator 19 becomes higher than the ten input electric potential, and at the moment when it becomes higher, the output of the comparator 19 increases. It turns on, turns off the transistor 21, and stops energizing the drying function 14.The user can know that the drying is finished when the drying air 8 stops blowing into the cleaning section. All you have to do is turn off the drying switch 13.

In the above-mentioned embodiment, since the user can clearly see when the drying is finished, there is no discomfort caused by incomplete drying, discomfort or anxiety caused by excessive drying, and the user can use the product with peace of mind.

FIG. 4 shows another circuit diagram of the part that activates the drying function in one embodiment of the present invention. Items with the same numbers as those in FIG. Omit. 2
2 is a relay, and 23 is a contact point of the relay 22.

In the circuit configuration shown in FIG. 4 above, when the user turns on the drying switch 13 to perform drying, the drying function 14 is energized and at the same time the relay 22 is also energized, and the contact 23 of the relay 22 is activated. Turn on. Thereby, even if the user turns off the drying switch 13 halfway, the drying function 14 continues to be energized. When the drying is completed and the transistor 21 is turned off, the drying function 14 and the relay 22 are stopped being energized, and the relay 22 is stopped.
Since the contact point 23 of No. 2 is also turned off, the blowing of the drying air 8 is automatically stopped.

In the circuit configuration shown in Fig. 4 above, the user does not need to keep pressing the drying switch 13 during drying, and can dry with a single touch, making it extremely convenient to use and without causing hand fatigue. .

6 and 6 show another embodiment of the sanitary cleaning device of the present invention, and FIG. 5 is a top view of a toilet bowl showing another embodiment of the present invention. In FIG. 6, the same numbers as in FIG. 1 indicate the same parts, and the explanation will be omitted. 24 is water stored in the distern 4;
Reference numeral 6 denotes a water filter installed in the distern 4, and this water filter 26 is submerged in the water 24. 26

27 is a fan that blows air to the drying air blowing lower;
8 is a motor that drives the fan 27, 29 is a heater that heats the air blown from the fan 27 to the optimum temperature for drying, and 30 is a heater that prevents the drying air 8 from containing moisture after it comes into contact with the cleaning part of the human body. 31 is a humidity sensor provided in the hot air passage of the suction pipe 3°. 32 is a controller.

Since FIG. 6 shows the humidity detection circuit of the part that activates the drying function in the embodiment of FIG. 6, the parts with the same numbers as those in FIG. 4 have the same functions and will not be described further. 1
3a and 13b are drying switches that are turned on and off in conjunction with each other.

In the configuration shown in FIG. 6 above, 1. When the user turns on the drying switches 13a and 13b to perform drying, the drying function 14 is energized and the relay 22 is also energized, turning on the contact 23 of the relay 22. When the warm air containing moisture hits the humidity sensor 31, the resistance value of the humidity sensor 31 decreases, so the comparator 19
The output of the transistor 21 is turned off and the transistor 21 is turned on.

Thereby, even if the user turns off the drying switches 13a, 13b midway, the drying function 14 continues to be energized.

As the drying progresses, the resistance value of the humidity sensor 31 increases, and when the drying is completed, the comparator 19 is turned on, the transistor 21 is turned off, and the
The contact 23 of No. 2 is also turned off to automatically end the drying.

The circuit configuration shown in FIG. 6 has the advantage of being able to monitor the dry state of the human body over a wide range.

9 H... In the above embodiment, an example was explained in which the absolute value of the resistance between the pair of electrodes 11 and 12 or the resistance of the humidity sensor 31 is detected, but the initial value is detected by the method of detecting the differential value. By adopting a configuration that ignores the influence of drying, it is possible to detect the completion of drying more accurately.

As described above, the sanitary cleaning device of the present invention includes a cleaning means for cleaning the part of the human body to be cleaned, a drying means for drying after cleaning, and a drying completion confirmation means for confirming the completion of the drying. This may cause discomfort due to incomplete drying, such as when residual water runs down your legs the moment you stand up from the toilet seat.
It solves the problem of getting caught on damp skin when wearing underwear or feeling a residual moisture after wearing it, and also eliminates the risk of low-temperature burns and dry skin due to excessive dryness. It is possible.
