<4> Operation and Action of Sanitary Washing Apparatus Next, the operation and action of the sanitary washing apparatus having the above configuration will be described.

  When the user enters the toilet room and the human body detection sensor 310 detects the human body, the control unit 700 opens the toilet lid 210 by driving the toilet seat toilet lid rotation mechanism according to the signal of the human body detection sensor 310, Energization of the toilet seat heater of the toilet seat 220 is started, and the temperature is raised within 10 seconds so that the seating surface of the toilet seat 220 is about 40 ° C. suitable for seating.

  When the user sits on the toilet seat 220, the seating detection sensor 230 detects the seating, and the control unit 700 receives the seating signal, so that the operation function of the cleaning function is operated by the operation switch 241 of the main body 200 and the operation switch 301 of the remote controller. Is possible.

  In addition, the control unit 700 starts driving the blower 630 of the deodorizing device 600, sucks the air in the toilet 110 from the air inlet 611 into the duct 610 as indicated by the arrow D1, and proceeds through the duct in the direction of the arrow D2. As shown by the arrow D3, the air passing through the honeycomb hole of the deodorizing body 620, sucked into the blower 630 from the suction port of the blower 630 as shown by the arrow D4, and discharged from the blower 630 is shown by the arrow D5. It is discharged downward from an exhaust port 612 provided in the bottom plate of the main body 200. The discharged air passes through a gap formed between the bottom plate of the main body 200 and the upper surface of the toilet 110, and is exhausted to the rear of the main body 200.

  During this time, the air containing the odorous substance sucked into the deodorizing device 600 is adsorbed on the pore walls of the honeycomb hole while passing through the honeycomb holes of the deodorizing body 620, and the odorous substance is catalyzed by the deodorizing body 620. Is decomposed and removed, and the air after passing through the deodorizing body 620 becomes almost odorless from which the odorous substance is removed, and is discharged from the exhaust port 612 into the toilet room.

  As described above, most of the odorous substances generated in the toilet 110 during the stool can be effectively prevented from being decomposed and removed by the deodorizing apparatus 600 and the odor of the entire toilet room being diffused.

  After the user finishes the stool and finishes the local cleaning by the cleaning means, the user gets up from the toilet seat 220, exits the toilet room, and the human body detection sensor 310 ends the detection of the human body, for example, after elapse of a predetermined time (for example, After 1 minute), the controller 700 stops driving the deodorizing device 600 and starts driving the electrostatic atomizer 800.

  When the controller 700 starts driving the electrostatic atomizer 800 according to a predetermined setting condition, energization to the blower 820, the Peltier element 835, the atomization electrode 832, and the counter electrode 833 is started.

  The blower 820 sucks air in the toilet room from the air inlet 811 provided at the bottom of the sleeve portion 240 of the main body 200 via the filter 850 and blows the air toward the electrostatic atomization unit 830. The air sucked from the intake port 811 as shown by the arrow E1 passes through the gaps between the barriers 812a, 812b and 912c as shown by the arrow E2, and is sucked from the intake port of the blower 820 as shown by the arrow E3.

  As shown in FIG. 6, a part of the air blown from the blower 820 toward the electrostatic atomization unit 830 as indicated by an arrow E4 is a cooling substrate 835a of the Peltier element 835, the atomization electrode 832, and the counter electrode 833. The air is blown toward the low temperature part. A part of the air passes through the heat radiation fins 836 of the electrostatic atomization unit 830 and is heated by heat radiation from the heat radiation fins 836. The air that has passed through the electrostatic atomizing unit 830 passes through the gaps between the barriers 815a and 815b of the discharge duct space 815 as shown by an arrow E5 and is blown downward, and the inspection lid 840 installed at the bottom of the discharge duct space 815. The wind direction is changed forward by the wind direction changing unit 843 and discharged from the discharge port 816 through the louver 851 into the toilet room.

  The air supplied to the low temperature part of the electrostatic atomizing unit 830 comes into contact with the cooling substrate 835a of the Peltier element 835, whereby moisture in the air is condensed and condensed water is generated. The generated condensed water is fed to the surface of the atomizing electrode 832, and by applying a high voltage of about 3500 V between the atomizing electrode 832 and the counter electrode 833, Rayleigh splitting occurs in the condensed water, and the nanometer size. The charged fine particle water is generated. That is, the air after passing through the electrostatic atomization unit 830 contains nanometer-sized charged fine particle water, and the charged fine particle water is discharged into the toilet room from the discharge port 816.

  The charged fine particle water discharged from the discharge port 816 scatters in the toilet room space and adheres to odorous substances floating in the toilet room, wall surfaces, ceiling surfaces, floor surfaces, and the like. Since the charged fine particle water is very small and can enter inside the pores on the wall surface, deodorizing and antifungal effects can be obtained against odorous substances and molds attached to the wall surface. .

  In particular, nanometer-sized charged fine particle water has the ability to decompose and remove odorous substances such as ammonia, acetaldehyde, acetic acid, methane, carbon monoxide, nitrogen monoxide, formaldehyde and sterilize various fungi. Deodorizing, sterilizing, and sterilizing effects can be exhibited against odorous substances and fungi that float and adhere to the wall and floor surfaces.

  In addition, in the case of a boy's small person who does not sit on the toilet seat 220, the deodorizing device 600 is not driven, but immediately after the human body detection sensor 310 finishes detecting the human body after leaving the user's toilet room, The electrostatic atomizer 800 starts to drive and stops after a predetermined time.

  On the other hand, when urination is performed outside the toilet 110 due to an abnormal operation at the time of boys' small use or a child's mischief, the discharge port 816 of the electrostatic atomizer 800 is disposed at a position lower than the upper surface of the toilet 110. The urine may enter the inside of the case 810 from the discharge port 816 via the louver 851 and adhere to the vicinity of the discharge port 816 and may be contaminated with a large amount of odorous substances.

  When such abnormal use is made and a large amount of odorous substance is accumulated, it is difficult to disassemble in a short time with the normal function of the electrostatic atomizer 800, so the inspection lid 840 is removed and the inspection lid 840 is washed. At the same time, the inside of the case 810 near the discharge port 816 can be cleaned from the inspection opening 817, and the function of the electrostatic atomizer 800 can be maintained.

  As described above, the sanitary washing device according to the present embodiment diffuses bad odors throughout the toilet room by deodorizing the stool for the user sitting on the toilet seat and the odor in the toilet bowl during the washing operation. When the toilet room is not in use, the electrostatic atomizer dissipates the charged fine particle water into the toilet room space, so that odorous substances floating in the toilet room space and the wall surface, ceiling surface, floor surface It is possible to decompose odorous substances by adhering and remove odors. Also, by sanitizing and sterilizing various fungi in the toilet room, the odors in the toilet room can be controlled over a long period of time. It can be maintained.

  Further, when the electrostatic atomizer is contaminated due to an abnormal operation during defecation, the function of the electrostatic atomizer can be maintained by removing and cleaning the inspection lid.

  As described above, the sanitary washing device according to the present invention can suppress the deodorization of the odorous substance immediately after the occurrence and the accumulated odorous substance and the odor generation of the apparatus main body. It can be applied to other uses.
