Reference numeral 14 is a storage box that stores each of the above-mentioned functions.

With the above configuration, after the private parts of the human body sitting on the toilet seat are washed with washing water, the buttocks wet with the washing water are dried with warm air. (For example, Japanese Unexamined Patent Application Publication No. 59-107142) Problems to be Solved by the Invention However, in the above configuration, warm air is applied to the door wet with washing water, so if the temperature inside the toilet is high in summer, the door may There was an unpleasant problem of the door becoming hot and sweating on the door.

The present invention is intended to solve these conventional problems, and aims to cool a heated door using warm air from drying.

Means for Solving the Problems In order to solve the above problems, the present invention and the sanitary washing/drying device have a warm air drying means for drying the door of the human body wet with washing water with warm air, and a means for changing the mind inside the toilet room. room temperature detection means for detecting;
After energizing the hot air drying means for a predetermined time, the hot air drying means is switched to a blowing mode based on a room temperature detection setting value of the room temperature detection means.

Effects According to the above-described configuration of the present invention, the heated door is automatically cooled by warm air in the summer when the room temperature of the toilet is relatively high.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figure 1, 15 is a drying relay R connected in parallel with the commercial power supply.
A blowing fan morph 10 is connected through the normally closed contact "Fa" of the blower fan motor 10. A drying heater 11 is connected in parallel with the blowing fan motor 10 through the normally closed contact RHb of the room temperature detection relay RH, and the hot air drying means Configure A.

The 16/fi control power source serves as a driving power source for the following control means.

17 is a drying operation switch, 18 is a drying stop switch,
A drying operation switch 17 is connected to the set terminal of the R-S flip 70 knob 19, and a drying stop switch 18 is connected to the reset terminal. The output terminal rQJ of the R-S flip 70 knob 19 is set to rLJ when the set terminal is rHJ, and is set to "HJK" when the reset terminal is rHJ.
The outputs are input to the G) and NPN) transistors 2o.

B is a drying control means, which includes a series circuit of a resistor 21 and a capacitor 22 connected to a control power source 16, a resistor 23, and a resistor 2.
A comparator 25 calculates the terminal voltage VT obtained by dividing the control power supply 16 by 4 and the terminal voltage Vc of the capacitor 22.
Enter. VT is input to the inverting terminal of the 25 comparators, and VC is input to the non-inverting terminal. The collector output of the NPN transistor 20 is connected to both ends of a capacitor 22 via a resistor 26 to form a timer circuit. The output terminal 27 of the comparator 25 is input to the gate G1. The output of gate G1 is input to gate G2, and the output is N
Drying relay RF is energized via PN transistor 28. The R-S flip 70 tube 19 is connected from the collector terminal of the NPN transistor 280 via the reset circuit 29.
Connect to the reset terminal of.

Next, the configuration of the room temperature detection means C for detecting the room temperature of the toilet will be explained. 29 is a thermistor that detects room temperature, and resistor 30
The resistor 31 and variable resistor 32 constitute a temperature detection bridge. The temperature detection side terminal voltage of the thermistor 29 examples is connected to the non-inverting input terminal of the comparator 33, and the heart change setting side terminal voltage on the variable resistor 32 side is connected to the inverting input terminal. The output terminal 34 of the comparator 33 energizes the room temperature detection relay RH via the NPN transistor 35 and also connects the gate G2.
connected to the input terminal of The diode 36 disables the operation of the temperature detection side so that room temperature detection starts after the timer circuit of the drying control means B operates.

Next, the operation will be explained based on the operation sequence diagram shown in FIG. After washing the private parts of the human body with washing water, turn on the drying switch 17 at time to R-S flip 70 knob 1
The rQJ output of 9 switches from rHJ to rLJ, and charging of the capacitor 22 via the resistor 21 begins. Then, both of the two input voltages to the gate Gl become "L", and the output becomes "H" by the NOR logic. Goo) G2 output becomes rHJ by OR logic and becomes dry relay RF
energize. Therefore, the contact RFa is closed, and the commercial power source 15 is supplied to the blower fan morph 10 and the drying heater 11, and drying of the door begins. When the terminal voltage v0 of the capacitor 22 reaches the timer time setting voltage vT, the output of the comparator 25 becomes "
Flip to "H". At this time, the diode 36 becomes reverse biased and a temperature detection operation becomes possible, but if the room temperature r does not reach the detected value voltage, the output of the comparator 33 remains unchanged and is fixed at "L". This is a so-called low room temperature state. Therefore, the room temperature detection relay RH remains off, and the output of the gate G1 is inverted to "L" by NOR logic, and the drying relay RF is turned off.
is turned off. Then, the voltage at the collector terminal of the NPN transistor 28 is inputted to the reset terminal of the R-87 lip-flop via the reset circuit 29, and hot air drying is stopped at time t1.

When the room temperature of the toilet is relatively high from time t2 to t4,
From time t2 to t3, as described above, the voltage at the output terminal 34 of the comparator 33 is inverted to rHJ at time t3.

Therefore, the room temperature detection relay RH is energized, the contact RHb is opened, and the peak 110 energization is stopped. On the other hand, dry relay RF
Since the output voltage of the comparator 33 is input to the gate G2, it does not turn off, and enters the so-called ventilation mode. Time t4
When the drying stop switch 18 is turned on, everything returns to its initial state.

In the above configuration, by turning on the drying operation switch, hot air drying operation is performed for a predetermined time, and when the room temperature of the toilet is high, it is possible to automatically switch to the ventilation mode. Additionally, the room temperature detection level can be set arbitrarily, and the drying stop switch allows you to set the drying time to your preference.

The same effect can be obtained by linking the seat switch built into the toilet seat and automatically stopping the air blowing when the toilet seat is stood up.

Effects of the Invention As described above, the sanitary washing and drying apparatus of the present invention provides the following effects.

The toilet is equipped with a room temperature detection means for detecting the room temperature of the toilet, and a drying control means for energizing the hot air drying means for a predetermined period of time and switching the hot air drying means to a blowing mode according to the room temperature detection setting value of the room temperature detection means. This has the effect of eliminating the discomfort of sweating on the door that becomes hot due to hot air drying during the summer when the room temperature of the toilet is high, and the discomfort of wearing hot clothes.
