(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, since the sanitary washing apparatus according to the present invention can deodorize both the odorous substance immediately after generation and the accumulated odorous substance, it can be applied to uses such as a deodorizing apparatus other than the sanitary washing apparatus.
