<Example>
The toilet seat apparatus 10 of an Example is attached on the toilet bowl main body 1 of a flush toilet bowl, as shown in FIG.1, FIG.2, FIG.4-6. The toilet body 1 has a toilet bowl 2. The toilet seat device 10 includes a toilet seat device main body 11 and a toilet seat 12 and a toilet lid 13 that are rotatably attached to the front portion of the toilet seat device main body 11. The toilet seat main body 11 incorporates various components (not shown) constituting various functional devices such as an ion generator 20 using a drying device and a local cleaning device.

  The toilet seat device body 11 is placed and fixed on the upper surface of the toilet body 1 behind the toilet bowl 2. The toilet seat 12 and the toilet lid 13 rotate on the toilet body 1 between a standing state and a lying state. The toilet lid 13 is in a lying state and the toilet bowl 2 is closed from above (see FIGS. 4 and 5).

  The toilet seat device 10 drives a motor (not shown) incorporated in the toilet seat device main body 11 based on the detection signal of the human body detection sensor 60 incorporated in the toilet seat device main body 11, and puts the toilet seat 12 and the toilet lid 13 upright and lying down. It can be automatically rotated to the state. That is, when the human body detection sensor 60 detects a person approaching the flush toilet, the toilet lid 13 rotates from the lying down state to the standing state, the person moves away from the flush toilet, and the human body detection sensor 60 stops detecting the person. The toilet lid 13 rotates from the standing state to the lying state. The toilet seat device 10 has a remote controller (not shown) having switches for driving various functional devices incorporated in the toilet seat device body 11. This remote controller is fixed to the wall of the toilet room where the flush toilet is installed. Further, by operating the toilet seat / toilet lid opening / closing switch of the remote controller, the motor can be driven to rotate the toilet seat 12 and the toilet lid 13 to the standing state or the lying state.

  The ion generator 20 uses a drying device having a fan 21 and a duct 22 that extends to the exhaust side of the fan 21 and has a blower port 23 at the tip. This drying device is incorporated in the toilet seat device main body 11, and includes a fan 21 having an air inlet 21A in the toilet seat device main body 11, and a duct 22 extending continuously from the case 21B of the fan 21 to the exhaust side. have. The duct 22 includes a duct body 22A that is continuous with the case 21B of the fan 21 and has a hollow inside, and a nozzle 22B that is housed in the duct body 22A so as to protrude freely.

  The duct body 22A accommodates a heating wire 24 as a heat source inside the fan 21 side. The rear end of the nozzle 22B opens and communicates with the inside of the duct body 22A. Further, as shown in FIG. 3, the nozzle 22 </ b> B has a closed tip and a blower opening 23 opened upward on the upper surface of the tip. The nozzle 22B protrudes forward and backward from the front end of the duct main body 22A by a pinion P provided on the rotation shaft of the motor M incorporated in the duct main body 22A and a rack R provided on the side surface of the nozzle 22B. Can do.

  As shown in FIGS. 1 to 6, the ion generator 20 using this drying device is configured by attaching an ion generator 25 that emits ions downward on the upper side of the air inlet 21 </ b> A of the fan 21. . In other words, the ion generator 25 can be arranged on the intake side of the fan 21 of the drying device and can release ions to the intake side of the fan 21.

  Thus, the ion generator 20 comprises the ion generator 20 using the fan 21 and the duct 22 of a drying apparatus. For this reason, an increase in the number of parts can be suppressed, and the ion generator 20 can be incorporated into the toilet seat device 10 even in a small space in the toilet seat device body 11.

  Therefore, the ion generator 20 of an Example can be easily integrated in the toilet seat apparatus 10 at low cost.

  The ion generator 20 includes a shutter 30 that opens and closes the front of the duct 22. The shutter 30 is pivotally supported around the horizontal axis at the lower front end of the toilet seat apparatus body 11. Further, the shutter 30 extends not only in front of the duct 22 of the ion generator 20 (in a state in which the nozzle 22B does not protrude) but also in front of the cleaning nozzle 40 of the local cleaning device as shown in FIG. . When the nozzle 22B of the ion generating device 20 protrudes from the duct main body 22A or the cleaning nozzle 40 of the local cleaning device protrudes from the nozzle main body 41, the shutter 30 is pushed forward and the front upward direction about the horizontal axis. Rocks. In addition, the shutter 30 is configured such that when the nozzle 22B of the ion generator 20 is accommodated in the duct main body 22A and the cleaning nozzle 40 of the local cleaning device is accommodated in the nozzle main body 41, the front of the duct 22 of the ion generator 20, And it will be in the state suspended so that the front of the washing nozzle 40 of a local washing | cleaning apparatus might be closed (refer FIG. 6). The shutter 30 hangs down so as to close the front of the duct 22 of the ion generator 20 and the front of the cleaning nozzle 40 of the local cleaning device, so that the duct 22 of the ion generating device 20 and the local cleaning device It is possible to prevent the urine scattered during the stool from adhering to the cleaning nozzle 40.

  The toilet seat device 10 incorporates a temperature sensor 51, a humidity sensor 52, and an odor sensor 53 in the toilet seat device body 11. The ion generator 20 can control the ion emission amount of the ion generator 25 according to the outputs of these sensors 51, 52, and 53. That is, when the temperature sensor 51 or the humidity sensor 52 detects that the temperature or humidity is higher than the set value, it is determined that the bacteria are likely to grow, and the ion emission amount of the ion generator 25 is increased. Further, when the odor sensor 53 detects that the odor is higher than the set value, the ion emission amount of the ion generator 25 is increased. For this reason, this toilet seat apparatus 10 can perform sterilization and deodorization in the toilet bowl 2 etc. favorably. In addition, the ion generator 25 can be driven efficiently to save power.

  The toilet seat apparatus 10 having such a configuration can operate as follows.

  When a user approaches the flush toilet in order to use the flush toilet with the toilet seat device 10 attached, the human body detection sensor 60 detects the user and the toilet lid 13 automatically changes from the lying state to the standing state. (See FIGS. 1 and 2).

  And the user of the flush toilet bowl sits on the toilet seat 12 and performs a toilet. After the toilet, the user operates a local cleaning switch of a remote controller (not shown) of the toilet seat device 10 to execute a local cleaning process. At this time, the cleaning nozzle 40 of the local cleaning nozzle protrudes from the nozzle body 41 and ejects cleaning water toward the collar.

  After finishing the local washing process, the user operates the drying switch of the remote controller of the toilet seat apparatus 10 to execute the buttocks drying process. That is, when the user operates the drying switch, the motor M incorporated in the duct main body 22A of the ion generator 20 rotates, and the nozzle 22B protrudes from the front end portion of the duct main body 22A by the rack and pinion mechanism, while the heating wire 24 Is energized, and the fan 21 rotates. Further, the ion generator 25 emits ions.

  At this time, as shown in FIGS. 1 and 2, the ion generator 20 generates hot air mixed with ions discharged from the ion generator 25 in a state where the nozzle 22B pushes up the shutter 30 and protrudes most forward. It sprays toward the user's buttocks seated on the toilet seat 12 from the air outlet 23 of the nozzle 22B. By blowing warm air mixed with ions having a beautifying effect on the buttocks, it is possible to achieve skin beautifying effects such as moisturizing the skin while drying the buttocks. In addition, the ion generator 20 projects the nozzle 22B forward from the duct body 22A, and discharges ions toward the buttocks of the user seated on the toilet seat 12 from the blower opening 23 opened upward from the tip of the nozzle 22B. Therefore, ions having a beautifying effect can be efficiently sprayed on the buttocks of the user who is seated on the toilet seat 12.

  Thereafter, the user operates the drying switch of the remote controller of the toilet seat device 10 to complete the buttocks drying process. That is, when the drying switch is operated during the buttock drying process, the motor M incorporated in the duct main body 22A of the ion generator 20 rotates reversely, and the nozzle 22B is housed in the duct main body 22A by the rack and pinion mechanism. Then, energization of the heating wire 24 is terminated, and the rotation of the fan 21 is stopped. Furthermore, the ion generator 25 ends the emission of ions. As a result, the shutter 30 hangs down so as to close the front of the duct 22 of the ion generator 20 and the front of the cleaning nozzle of the local cleaning device.

  Thereafter, when the user who has left the toilet seat 12 moves away from the flush toilet and the human body detection sensor 60 no longer detects the user, the toilet lid 13 automatically rotates from the standing state to the lying state. That is, as shown in FIG.4 and FIG.5, the toilet lid 13 will be in the state which closed the toilet bowl 2 from upper direction. In this state, the toilet seat apparatus 10 executes the sterilization / deodorization process in the toilet bowl 2 for a set time.

  That is, when the toilet lid 13 rotates from the standing state to the lying state and the toilet bowl 2 is closed from above, the motor M incorporated in the duct body 22A of the ion generator 20 automatically rotates. With the rack and pinion mechanism, the fan 21 rotates while the nozzle 22B moves forward until the rear edge of the air blowing port 23 of the nozzle 22B protrudes slightly forward from the front end of the duct body 22A. Further, the ion generator 25 emits ions.

  At this time, the ion generator 20 ejects air mixed with ions from the air outlet 23 in a state where the air outlet 23 is positioned below the shutter 30 while the nozzle 22B pushes up the shutter 30. For this reason, as shown in FIG. 4, the air which ion mixed in collides with the lower surface of the shutter 30, and the ventilation direction is changed below. That is, air mixed with ions can be blown toward the surface of the toilet bowl 2. For this reason, when this ion generator 20 is incorporated in the toilet seat main body 11, the surface of the toilet bowl 2 can be sterilized and deodorized favorably by ions.

  Further, the ion generator 20 diffuses ions into the toilet bowl 2 with the toilet lid 13 closing the toilet bowl 2 from above. For this reason, ions can be filled in the stool 2 which has become a substantially closed space, and sterilization and deodorization in the stool 2 can be effectively performed.

  After the start of the sterilization / deodorization process in the toilet bowl 2, when the set time has elapsed, the sterilization / deodorization process in the toilet bowl 2 is terminated. That is, after the start of the sterilization / deodorization process in the toilet bowl 2, when the set time elapses, the motor M incorporated in the duct body 22A of the ion generator 20 automatically reversely rotates, and the rack and pinion mechanism Thus, the rotation of the fan 21 is stopped while the nozzle 22B is housed in the duct body 22A. Furthermore, the ion generator 25 ends the emission of ions.

  In the sterilization / deodorization process in the toilet bowl 2, the amount of ions released by the ion generator 25 is controlled according to the outputs of the temperature sensor 51, the humidity sensor 52, and the odor sensor 53. That is, when the temperature sensor 51 or the humidity sensor 52 detects that the temperature or humidity is higher than the set value, it is determined that the bacteria are likely to grow, and the ion emission amount of the ion generator 25 is increased. Further, when the odor sensor 53 detects that the odor is higher than the set value, the ion emission amount of the ion generator 25 is increased.

  In addition, the toilet seat device 10 is configured such that when a flush toilet is cleaned, a cleaner or the like operates a sterilization / deodorization switch for the toilet seat device body of the remote controller to perform a sterilization / deodorization process in the toilet seat device body 11. Can be executed. That is, when the cleaner or the like operates the toilet seat body disinfecting / deodorizing switch, the fan 21 rotates reversely for a set time and the ion generator 25 releases ions as shown in FIG. As a result, the toilet seat device 10 can diffuse ions in the toilet seat device main body 11, and thus can be easily sterilized and deodorized in the toilet seat device main body 11.
