A DC current of about 0 to 1 V is applied to the Peltier element 835 by the control unit 700.

  A sharp atomizing electrode 832 is installed on the cooling substrate 835 a of the Peltier element 835, and water condensed on the cooling substrate 835 a of the Peltier element 835 is conveyed to the atomizing electrode 832.

The air flow in the direction of is referred to as “forward direction”, and the air flow in the opposite direction is referred to as “reverse direction”. Further, by changing the rotational speed of the DC motor, the operation mode can be switched between two stages of “strong” and “weak”.

When the blower 820 is driven in the “forward direction” operation mode, the air in the main body 200 is sucked from the communication port 816 and blown toward the electrostatic atomization unit 830. The air inside the main body is a highly humid air sucked from the toilet bowl, and is supplied to the deodorizing device 600 through a communication air passage. The heat exchanger 460 installed in the main body, other driving mechanisms, etc. It is in a state where the temperature has been raised somewhat due to heat generation.

  The air supplied to the electrostatic atomization 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, resulting in a nanometer size. The charged fine particle water is generated.

  Further, since the discharge between the atomizing electrode 832 and the counter electrode 833 is performed in the air with the generation of the charged fine particle water, oxygen in the air reacts to generate ozone as a by-product. Like the charged fine particle water, ozone has a deodorizing function, a sterilizing function, and a disinfecting function, but has an ozone odor that is a peculiar bad odor.

Is done. The charged fine particle water discharged from the discharge port 814 is scattered in the toilet room space and adheres to an odor substance floating in the toilet room, a wall surface, a ceiling surface, a floor surface, or 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 can decompose and remove odorous substances such as ammonia, acetaldehyde, acetic acid, methane, carbon monoxide, nitrogen monoxide and formaldehyde, and adheres to the walls and floors of the toilet room. Odorous substances can be deodorized.

  Further, ozone has a deodorizing function, a sterilizing function, and a sterilizing function as in the case of the charged fine particle water, but is accompanied by an ozone odor which is a peculiar bad odor. Since the ozone odor becomes stronger as the concentration of ozone increases, the odor can be reduced by diffusing and lowering the concentration. In addition, since ozone is an unstable molecule, it is naturally converted into oxygen molecules in a relatively short time and the odor disappears.

  The electrostatic atomization unit 830 of the electrostatic atomizer 800 according to the present embodiment is provided with a condensed water generation unit 831 by the Peltier element 835 and supplies water from the air. The method is not limited to the method, and it is possible to generate charged fine particle water even in a configuration in which prestored water is supplied to the atomization electrode.

  At the time indicated by H in the figure when the linked air blowing operation for a predetermined time is completed, the control unit 700 stops driving the deodorizing device 600 and the electrostatic atomizing device 800.

  When the user enters the toilet room while the electrostatic atomizer 800 is being driven and the human body detection sensor 310 detects the human body, the electrostatic atomizer 800 and the deodorizer 600 are stopped.

  As described above, the sanitary washing device according to the present embodiment diffuses bad odors throughout the toilet room by directly deodorizing the stool for the user sitting on the toilet seat and the odor in the toilet bowl during the washing operation. After the stool is finished, the deodorizing device and the electrostatic atomizing device are driven in conjunction with each other, and the charged fine particle water generated by the electrostatic atomizing device is diffused into the toilet room space. Odors in the room space, odorous substances adhering to the wall surface, ceiling surface, floor surface, and fungi such as mold can be decomposed and removed, so the odor in the toilet room can be suppressed for a long time. Is something that can be done.

  In addition, the deodorizing device and the electrostatic atomizer are driven in the reverse direction to drive the deodorizing unit and the deodorizing unit in the sanitary washing device main body and in the deodorizing device by decomposing and removing them. The activation period can be extended.

In addition, when the electrostatic atomizer is stopped, after stopping the operation of the electrostatic atomizer unit, by stopping the blower after a lapse of a predetermined time, all charged fine particle water generated in the electrostatic atomizer And ozone can be widely diffused in the toilet room space, and the entire toilet room is effectively deodorized and sterilized by effectively utilizing the function of all charged fine particle water generated by the electrostatic atomizer. At the same time, by diffusing and diluting ozone, it is possible to reduce the ozone odor, which is a bad odor that ozone itself holds, and to maintain the comfort of the toilet room.

  In the present embodiment, the blower of the deodorizing device and the electrostatic atomizer is configured to be able to switch between two operation modes of “strong” and “weak”, but is not limited to this. The blower of either one or both of the deodorizing device and the electrostatic atomizing device can exhibit the basic functions of deodorizing and sterilizing even if it is always operated at a constant strength. In particular, in the air blowing operation of only the blower performed after the operation of the electrostatic atomizing unit is completed, an approximate effect can be obtained by extending the operation time.

  In the present embodiment, the hollow portion in the main body is used as the communication air passage. However, the present invention is not limited to this, and a dedicated duct may be arranged and used as the communication air passage.

  In the present embodiment, a communication air passage is provided between the deodorizing device and the electrostatic atomizing device, and the deodorizing device and the electrostatic atomizing device are operated in conjunction with each other. The configuration of the deodorizing device is not limited to this, the deodorizing device has a dedicated intake port and exhaust port, and the electrostatic atomizer has a dedicated intake port and discharge port. Even when the soaking apparatus is operated individually, the deodorizing function and the sterilizing and sanitizing function of the deodorizing apparatus and the electrostatic atomizing apparatus can be exhibited.

(Embodiment 2)
The configuration of the sanitary washing device 100 in the present embodiment is the same as that in the first embodiment, but the driving pattern of the deodorizing device 600 and the electrostatic atomizer 800 is different from the first embodiment.

  In the first embodiment, the operation of the deodorizing device 600 and the electrostatic atomizing device 800 is controlled based on the detection signals of the human body detection sensor 310 and the seating detection sensor 230. In the present embodiment, however, a timer is additionally provided. It is the point which added the function in which the deodorizing apparatus 600 and the electrostatic atomizer 800 are controlled based on a function.

  The controller 700 has a 24-hour count timer function, and drives the deodorizer 600 and the electrostatic atomizer 800 at a preset time. The drive pattern is the same as the drive from time D to time H shown in FIG.

  The time for starting operation is basically set to midnight when the sanitary washing device 100 is not used. This operation start time can be changed by operating the switch of the remote controller 300.

  By adding the above drive, for example, even when the sanitary washing device 100 is not used for a long period of time, the deodorizing device 600 and the electrostatic atomizer 800 are driven once a day. In addition, it is possible to suppress the propagation of odorous substances in the main body 200, and it is possible to more reliably suppress the odor in the toilet room over a long period of time.

  In the present embodiment, the operation start time is set to a predetermined time by the timer function. However, the operation start time is not limited to this. For example, the control unit 700 has a learning function and the sanitary washing device 100 is not used. The operation start time may be set based on the accumulated data.

Also, instead of setting the operation start time in units of 24 hours, when the sanitary washing device 100 is not used for a long time, for example, when the human body detection sensor 310 is not reused within 48 hours after completing the human body detection. You may make it start the drive of the deodorizing apparatus 600 and the electrostatic atomizer 800. FIG. Thereby, the deodorizing apparatus 600 and the electrostatic atomizer 800 are not driven more than necessary, and an energy saving effect can be obtained.

  As described above, the sanitary washing device according to the present invention can effectively use charged fine particle water and suppress ozone odor when the electrostatic atomizer is stopped. It can also be applied to.
