It is provided as follows.

  Further, the toilet seat apparatus body 1 has a built-in electrostatic atomizer 7 that generates a fine mist-like charged fine particle liquid having a nanometer size particle diameter and discharges the charged fine particle liquid toward the surface of the operation panel 6. It is. This electrostatic atomizer 7 has a structure schematically shown in FIG. 2 and is an elongated rod-shaped atomizing electrode 8 and an atomizing liquid supply means for supplying the atomizing liquid to the atomizing electrode 8. By applying a high voltage to the atomizing electrode 8 between the counter electrode 10 and the ring-shaped counter electrode 10 installed at a position facing the tip of the atomizing electrode 8. The main body is formed by the voltage applying means 11 for generating the charged fine particle liquid based on the atomized liquid by the electroatomization phenomenon and the discharge flow path 12 for discharging the generated charged fine particle liquid to the outside.

  The Peltier module 9 has a cooling side and a heat radiating side. The atomizing electrode 8 is erected on a cooling plate 13 connected to the cooling side to cool the atomizing electrode 8 itself. Although the condensed water used as an atomization liquid is directly produced | generated on the surface, you may comprise an atomization liquid supply means by another structure. Further, a heat radiation fin 14 is connected to the heat radiation side of the Peltier module 9.

However, the operation may be set to be turned off after a predetermined time has elapsed since the switch to the closed state of the toilet lid 3 was detected.

  FIG. 4 shows a control example when the electrostatic atomizer 7 is turned on / off based on the detection signal of the seating sensor 4. In this control example, when it is detected by the detection signal of the seating sensor 4 that the human body is not seated on the upper surface of the toilet seat 2 (hereinafter referred to as “seat off state”), the atomizing electrode by the voltage applying means 11 is used. Only when the high voltage application to 8 is stopped and it is detected by the detection signal of the seating sensor 4 that the human body is seated on the upper surface of the toilet seat 2 (hereinafter referred to as “seat-on state”). The control means 17 is provided so that the high voltage application to the atomization electrode 8 by 11 may be performed.

The discharged charged fine particle liquid adheres to the surface of the operation panel 6 located immediately before the discharge port 15 and performs sterilization, deodorization and the like automatically and promptly. In the illustrated control example, the operation of the electrostatic atomizer 7 is turned off when it is detected that the seating-on state has been switched to the seating-off state. You may set so that driving | running | working may be turned off after predetermined time progress, after detecting a change.

  FIG. 5 shows a control example when the electrostatic atomizer 7 is turned on / off based on the detection signal of the entrance / exit sensor 5. In this control example, when it is detected by the detection signal of the entrance / exit sensor 5 that the human body is leaving the toilet space (hereinafter referred to as “exit state”), the atomizing electrode by the voltage application means 11 is used. Only when the application of a high voltage to 8 is stopped and the human body enters the toilet space (hereinafter referred to as “room entry state”) according to the detection signal from the entrance / exit sensor 5, the voltage is applied. The control means 17 is provided so that the high voltage application to the atomization electrode 8 by the application means 11 may be performed.

  As a result, it is possible to set so that the charged fine particle liquid is generated by the electrostatic atomizer 7 only during the entrance state, and discharged from the discharge port 15 toward the operation panel 6. The discharged charged fine particle liquid adheres to the surface of the operation panel 6 located immediately before the discharge port 15 and performs sterilization, deodorization and the like automatically and promptly. In the illustrated control example, the operation of the electrostatic atomizer 7 is turned off when it is detected that the room has been switched from the entry state to the exit state, but the switch to the exit state is detected.
