<1-3. Configuration of deodorizing unit>
Next, the configuration of the deodorizing unit 40 in the first embodiment will be further described with reference to FIG. FIG. 5 is an explanatory diagram of the deodorizing unit 40 in the first embodiment. As shown in FIG. 5 and described above, the deodorizing unit 40 includes the first deodorizing section 41, the second deodorizing section 42, the fan 43 serving as a blower, and the damper 44.

  The first deodorizing section 41 deodorizes the inside of the toilet bowl 2a (see FIG. 1). The first deodorizing section 41 includes a first duct 411, a first deodorizing filter 412, an intake port 45, and a first exhaust port 413. The first duct 411 is an air passage through which air sucked from the intake port 45 by being sucked by the fan 43 flows, and guides the sucked air to the first exhaust port 413.

  The first deodorizing filter 412 is provided in the first duct 411 so as to block an air path. The first deodorizing filter 412 has, for example, a porous structure, and deodorizes air in the toilet bowl 2a (see FIG. 1) as described above.

  The second deodorizing section 42 includes a second duct 421, a second deodorizing filter 422, an intake port 45, and a second exhaust port 423. The second duct 421 branches off from the first duct 411 to form an air passage different from that of the first duct 411. The second duct 421 is an air passage through which air sucked from the air inlet 45 common to the first deodorizing section 41 by being sucked by the fan 43 flows, and guides the sucked air to the second air outlet 423.

  Further, the second duct 421 includes a throttle portion 424 provided in a rib shape so as to narrow an air path formed by the second duct 421 downstream of the damper 44 in the direction of air flow.

  As described above, since the air path is narrowed downstream of the damper 44, a pressure loss can be generated for the air flowing in the second duct 421. By intentionally reducing the air volume in the second duct 421, it is possible to obtain an air volume suitable for deodorizing the toilet room without finely controlling the fan 43. Thus, the device configuration can be simplified, and control of the fan 43 is not required, so that malfunction of the fan 43 can be suppressed.

  The second deodorizing filter 422 is provided in the second duct 421 so as to block the air path. The second deodorizing filter 422 has, for example, a porous structure, and deodorizes air in the toilet room 100 (see FIG. 1) as described above. The first deodorizing filter 412 and the second deodorizing filter 422 are arranged in parallel.

  As described above, one fan 43 is provided for the deodorizing unit 40, and is shared by the first deodorizing unit 41 and the second deodorizing unit 42. The fan 43 is open toward the first deodorizing filter 412 so that the air outlet 431 faces the first deodorizing filter 412.

  Since the air outlet 431 of the fan 43 is open toward the first deodorizing filter 412 in this manner, the first deodorizing filter can be used when performing toilet bowl deodorization that requires instantaneous deodorization in a short time. The pressure loss of the air toward 412 can be suppressed.

  The damper 44 is provided upstream of the first deodorizing filter 412 and the second deodorizing filter 422 in the air flow direction. The damper 44 is driven to open and close by a damper driving unit 441 to switch the air path. The damper 44 closes at least a part of the first duct 411 or the second duct 421 as described above. The damper 44 may, for example, completely close (completely close) the first duct 411 or the second duct 421, or close (partially close) while partially opening.

  Further, the damper 44 is constantly urged to close the first duct 411, that is, in a direction to close the first duct 411. The damper closes the first duct 411 when not driven by the damper driving unit 441, and closes the second duct 421 against the urging force when driven by the damper driving unit 441. Therefore, when the driving of the damper 44 is stopped, the first duct 411 is automatically closed by the urging force. As a result, less power is required for driving the damper 44, and energy can be saved.

<1-4. Deodorizing operation of deodorizing unit>
Next, the deodorizing operation of the deodorizing unit 40 will be described with reference to FIGS. 6A and 6B. FIG. 6A is an explanatory diagram of the deodorizing operation of the first deodorizing unit 41 in the deodorizing unit 40. FIG. 6B is an explanatory diagram of the deodorizing operation of the second deodorizing unit 42 in the deodorizing unit 40. 6A and 6B, the flow of air is indicated by white arrows.

  As shown in FIG. 6A, when performing toilet bowl deodorization in the deodorizing unit 40, the damper 44 is driven by the damper driving unit 441 (see FIG. 5) to close the second duct 421. Thereby, an air path by the first duct 411 is formed. As shown in FIG. 6B, when the deodorizing unit 40 performs the toilet deodorization, the driving of the damper 44 by the damper driving unit 441 is stopped, and the damper 44 is moved by the urging force to close the first duct 411.

<1-5. Damper drive control>
Here, an example of a processing procedure of the damper drive control will be described with reference to FIG. FIG. 7 is a flowchart illustrating a processing procedure of damper drive control. In normal times when a user is not in the room, the deodorizing unit 40 may perform toilet room deodorization. As shown in FIG. 7, the damper 44 closes the first duct 411 and opens the second duct 421 (Step S101).

  The control unit 50 determines whether or not the user's seating is detected by the seating detection sensor 30 (Step S102). When the seating detection sensor 30 detects seating (Step S102: Yes), the control unit 50 drives the damper 44 via the damper driving unit 441 (Step S103).

  In this case, when air is being sucked by the fan 43 when the seat detection sensor 30 detects seating, the control unit 50 temporarily stops the suction of air, that is, temporarily stops driving the fan 43. Subsequently, the damper 44 moves while opposing the urging force and closes the second duct 421 (Step S104).

  Here, when the fan 43 is temporarily stopped, the control unit 50 restarts the suction of air after the timing of step S104, that is, after the damper 44 completes closing the second duct 421 (fan 43 is driven again). When the damper 44 closes the second duct 421, an air path is formed by the first duct 411, and the control unit 50 performs deodorization in the toilet bowl 2a.

  The control unit 50 stops driving the damper 44 by the damper driving unit 441 when a predetermined time has elapsed since the start of deodorization in the toilet bowl 2a (step S105). When the driving by the damper driving unit 441 is stopped, the damper 44 moves in the direction of closing the first duct 411 by the urging force to close the first duct 411 and open the second duct 421 (step S106). ), The toilet room 100 can be deodorized.
