  The water storage part 51 e is a part that stores water from the water pipe 3. The water storage part 51e is formed in a box shape that opens upward, and is disposed at the bottom of the deodorizing casing 51 and below the deodorizing part 51d2. A connection port 51e1 of the water reservoir 51e is connected to the other end of the water diversion channel B. The water reservoir 51e is supplied with water from the water pipe 3 via the diversion channel B. The water reservoir 51e constitutes a water ejection device 53 (described later).

  The water outlet 51f is a flow path for leading water ejected by the water ejection device 53 to the first opening 51a. In the first embodiment, the water outlet 51f guides the water ejected by the water ejection device 53 to the first opening 51a via the water reservoir 51e (details will be described later).

  The water lead-out portion 51f is formed by the bottom wall of the deodorizing casing 51 that forms the gas introduction portion 51d1 of the gas flow path 51d. The rear end portion of the water outlet 51f is connected to the upper end of the water reservoir 51e. Further, the water outlet 51f is formed so as to be inclined downward from above as it goes from the rear to the front. Therefore, when the water from the water supply pipe 3 is supplied to the water storage part 51e, the water stored in the water storage part 51e overflows from the water storage part 51e, passes through the water outlet part 51f, and then the toilet bowl part. 2b (see the single-dot dashed arrow in FIG. 4).

  The fan device 52 is disposed in the gas flow path 51d, sucks gas from the first opening 51a into the gas flow path 51d, and discharges the gas sucked into the gas flow path 51d from the second opening 51b. is there. The fan device 52 is disposed in the gas outlet 51d4. That is, the fan device 52 is disposed so as to be located above the water storage portion 51e. The fan device 52 is a sirocco fan. The fan device 52 includes a cylindrical fan 52a, a fan casing 52b, and a fan motor 52c.

  The cylindrical fan 52a is formed in a cylindrical shape having an intake port 52a1 that sucks gas at one end side (rear end side) while the axial direction is along the front-rear direction. The cylindrical fan 52a has a plurality of blades 52a2 on the side (see FIG. 5). The cylindrical fan 52a is rotationally driven to suck gas inward from the suction port 52a1 along the axial direction, and the gas sucked inward is radially outward from between adjacent blades 52a2 (fan casing 52b). (Refer to the thin solid arrows shown in FIGS. 4 and 5).

  The fan casing 52b accommodates the cylindrical fan 52a in a rotatable manner. The fan casing 52b is formed in a cylindrical shape whose axial direction is parallel to the axial direction of the cylindrical fan 52a. The fan casing 52b is formed with a suction port 52b1 for sucking gas and a discharge part 52b2 (see FIG. 5) for discharging gas. The suction port 52b1 is provided so as to open at a position facing the suction port 52a1 of the cylindrical fan 52a. The discharge part 52b2 is a duct provided on the side wall 52b4 and having a discharge port 52b3 for discharging gas toward the side (left side) of the fan casing 52b (see FIG. 5).

  The fan device 52 is attached to the deodorizing casing 51 so that the suction port 52b1 opens rearward and the discharge port 52b3 is connected to the second opening 51b. Moreover, as shown in FIG. 5, the fan casing 52b is formed with a first through hole 52b5 that constitutes a communication water channel 50a described later. The first through hole 52b5 is a hole that is formed in the discharge part 52b2 and communicates the inside of the fan casing 52b and the third opening 51c.

  The fan motor 52c is a motor that rotationally drives the cylindrical fan 52a. As shown in FIG. 4, the fan motor 52c is disposed outside the fan casing 52b. The output shaft 52c1 of the fan motor 52c passes through the second through hole 52b6 of the fan casing 52b and is fixed so as to rotate integrally with the cylindrical fan 52a. The output shaft 52c1 is supported by the second through hole 52b6 so as to be rotatable relative to the fan casing 52b and liquid-tight. The fan motor 52 c is rotationally driven by a control signal from the control device 70.

  The water ejection device 53 is supplied with water from the water pipe 3 and gas sucked into the gas flow channel 51d by the fan device 52 between the first opening 51a and the fan device 52 in the gas flow channel 51d. The water is spouted out. Specifically, the water ejection device 53 ejects water in the form of a mist to the deodorizing unit 51d2 (see the thin broken line arrow). The water ejection device 53 includes a vibrator 53a and the water storage part 51e described above.

  The vibrator 53 a is an ultrasonic vibrator that vibrates when a high-frequency AC voltage is applied from the control device 70. The vibrator 53a is formed by sandwiching a piezoelectric ceramic (not shown) between a pair of electrodes (not shown). The vibrator 53a is disposed at the bottom of the water reservoir 51e. When the water reservoir 51e is almost full, the vibrator 53a vibrates, and the water in the water reservoir 51e is ejected from the water surface S in the form of a mist. The height from the bottom surface of the water reservoir 51e to the water surface S is set to a predetermined height. The predetermined height is a height at which water is sprayed in the form of a mist by the vibration of the vibrator 53a.

  Moreover, the deodorizing function part 50 is further provided with the communication water channel 50a. The communicating water channel 50a is a channel that communicates the inside of the fan casing 52b with the water outlet 51f. The communication water channel 50a includes a first through hole 52b5, a third opening 51c, a deodorizing part 51d2, and a water storage part 51e. The communication water channel 50a guides the water sucked into the fan casing 52b to the water outlet 51f (described later).

  The seating sensor 60 is a sensor that detects a user seated on the toilet seat 20. The seating sensor 60 is an infrared distance sensor that detects the distance to the object. The seating sensor 60 is disposed in the upper part inside the main body casing 10a.

  When the user is seated on the toilet seat 20, the distance between the user and the seating sensor 60 is relatively short. Thereby, when the detection result of the seating sensor 60 is equal to or less than the predetermined distance, the seating sensor 60 outputs an ON signal to the control device 70. On the other hand, when the detection result of the seating sensor 60 is longer than a predetermined distance because the user is not seated on the toilet seat 20, the seating sensor 60 outputs an off signal to the control device 70. The predetermined distance is actually derived by experiments and the like.

  Moreover, the warm water washing toilet seat apparatus 1 is further provided with the disinfection provision part 80 which is provided between the water pipe 3 and the water ejection apparatus 53, and provides disinfection property to water. Specifically, the sterilization imparting unit 80 is disposed in the diversion channel B. The sterilization imparting unit 80 includes a sterilization casing 81 and a sterilizing agent 82.

  The sterilization casing 81 is formed in a hollow box shape in which water flows inside. The sterilization casing 81 guides water from the branch portion L1a (water pipe 3) to the water storage portion 51e. The sterilization casing 81 accommodates a sterilizing agent 82.

  The disinfectant 82 is an aggregate of a plurality of disinfecting glasses. The sterilizing glass is a phosphate glass containing silver oxide. Phosphate glass has solubility in water. When the phosphate glass is dissolved in water, the silver oxide elutes silver ions exhibiting a bactericidal effect in the water. The silver oxide is, for example, silver oxide.

  Next, the deodorizing operation for removing the odor of the gas in the toilet bowl 2b by the deodorizing function unit 50 of the warm water washing toilet seat apparatus 1 will be described with reference to the time chart of FIG. When the warm water washing toilet seat device 1 is in a standby state (a state in which the user is not seated), an off signal is output from the seating sensor 60. In this case, the control device 70 turns off (non-energized) the water ejection device 53 (vibrator 53a), the fan device 52 (fan motor 52c), and the water supply device 41. In this case, the control device 70 turns off the heater 43a and controls the flow path switching valve 45a to connect the fourth connection water channel L4 and the drainage channel D.

  In the case where the warm water washing toilet seat apparatus 1 is in the standby state, the deodorizing operation is started when the output of the seating sensor 60 is switched from the off signal to the on signal by the user sitting (time t1). First, the control device 70 turns on the water supply device 41 for a first predetermined time Tm1. Thereby, the water from the water supply pipe 3 is supplied to the water storage part 51e via the diversion channel B, and the water storage part 51e becomes almost full. The first predetermined time Tm1 is set to a time when the water reservoir 51e is almost full. Moreover, since the water from the water supply pipe 3 passes the sterilization imparting unit 80, silver ions are supplied to the water.

  When the first predetermined time Tm1 has elapsed, the control device 70 turns on the water ejection device 53 (time t2). Thereby, since a voltage is applied to the vibrator 53a, the water in the water storage section 51e is jetted in a mist form to the deodorizing section 51d2. Furthermore, when the second predetermined time Tm2 has elapsed (time t3), the control device 70 turns on the fan device 52. Thereby, the fan motor 52c rotationally drives the cylindrical fan 52a, and the gas in the toilet bowl 2b is sucked into the gas flow path 51d through the first series opening 10b1 and the first opening 51a. The second predetermined time Tm2 is a time during which at least the deodorizing part 51d2 is filled with mist-like water.

  The gas sucked into the gas flow channel 51d flows through the deodorization part 51d2 through the gas introduction part 51d1. At this time, the water ejection device 53 ejects water into the gas sucked into the gas flow path 51d by the fan device 52 in the form of a mist. Thereby, since the water-soluble odor contained in gas adheres to mist-like water, the odor contained in gas is removed. Moreover, floating substances (dust) such as dust contained in the gas are removed by adhering to water. Furthermore, since water contains silver ions, bacteria and molds contained in the suspended matter are sterilized. A part of the mist-like water is recovered by the water storage part 51e by falling by its own weight. On the other hand, the mist-like water which did not fall to the water storage part 51e flows into the direction change part 51d3.

  Further, the gas from which the odor or the like has been removed passes through the deodorizing unit 51d2 and flows through the direction changing unit 51d3. Since the direction in which the gas and the mist-like water flow is changed in the direction changing unit 51d3, the gas and the mist-like water are further mixed. Thereby, the odor and suspended | floating matter contained in gas are further removed with mist-like water. At this time, a part of the mist-like water falls into the water reservoir 51e and is collected. On the other hand, the mist-like water that has not fallen into the water storage part 51e and the gas from which the odor has been removed flow to the gas outlet part 51d4.

  The gas from which the mist-like water and odor are removed flows through the gas outlet 51d4 and is sucked into the fan device 52 from the suction port 52b1. As shown in FIG. 5, the gas sucked from the suction port 52b1 passes through the fan casing 52b and is discharged to the outside of the main body 10 through the discharge port 52b3, the second opening 51b, and the second communication port 10c1. (See thin solid arrows).

  On the other hand, the mist-like water sucked into the fan casing 52b from the suction port 52b1 flows out radially between the adjacent blades 52a2 of the cylindrical fan 52a, as indicated by a fine dotted line. It adheres to the inner surface of the side wall 52b4 of 52b. And the water in this fan casing 52b is pushed by the gas which flows in the fan casing 52b, flows along the inner surface of the side wall 52b4, and flows into the discharge part 52b2. Furthermore, the water in the fan casing 52b is led out from the first through hole 52b5 and the third opening 51c to the deodorizing part 51d2 and collected in the water storage part 51e. That is, the water in the fan casing 52b flows through the communication water channel 50a.

  When a third predetermined time Tm3 (for example, 1 minute) elapses from the time when the output of the seating sensor 60 is switched from the on signal to the off signal (time t4) due to the user leaving the toilet seat 20, the time (time) t5) The control device 70 turns off the water ejection device 53 and the fan device 52. Furthermore, at this time (time t5), the control device 70 turns on the water supply device 41 for the first predetermined time Tm1. Thereby, the water of the water storage part 51e (communication water channel 50a) overflows from the water storage part 51e, is led out to the first opening part 51a through the water lead-out part 51f, and in the toilet bowl part 2b through the first series opening 10b1. To be discharged. Thus, the communication water channel 50a guides the water sucked into the fan casing 52b to the water outlet 51f.

  The water in the water storage section 51e at this time (time t5) includes water recovered after being ejected by the water ejection device 53 and recovered after being sucked into the fan casing 52b. . Therefore, the water of the water storage part 51e contains the odor and floating matter removed from gas. Therefore, the odor and floating substances removed from the gas are discharged into the toilet bowl 2b through the water outlet 51f together with water.

  And the control apparatus 70 turns off the water supply apparatus 41 at the time of 1st predetermined time Tm1 progressing (time t6). Thereby, the warm water washing toilet seat apparatus 1 returns to a standby state. As described above, the water outlet 51f leads the water ejected by the water ejection device 53 to the first opening 51a. The fan device 52 sucks the water ejected by the water ejecting device 53 into the fan casing 52b. Furthermore, the communication water channel 50a constituted by the first through hole 52b5, the third opening 51c, the deodorizing part 51d2, and the water storage part 51e communicates the inside of the fan casing 52b with the water outlet part 51f in the fan casing 52b. The sucked water is led out to the water lead-out part 51f.

  According to the present embodiment, the warm water washing toilet seat device 1 is attached to the seat-type toilet 2 having the toilet bowl 2b, and the washing function unit 40 and the stool that wash the local part of the human body with the water supplied from the water pipe 3 The main body part 10 which accommodates the deodorizing function part 50 which removes the odor contained in the gas in the bowl part 2b is provided. The deodorizing function part 50 connects the first opening part 51a that opens toward the inside of the toilet bowl part 2b and the second opening part 51b that opens toward the outside of the main body part 10 so that gas can flow therethrough.

Therefore, it is possible to suppress the discharge of water with odors and floating substances attached to the outside. Therefore, it is possible to suppress odors and suspended matter from being discharged into the toilet room and humidifying the toilet room.

  The fan device 52 sucks the water ejected by the water ejecting device 53 into the fan casing 52b. The deodorizing function unit 50 further includes a communication water channel 50a that communicates the inside of the fan casing 52b with the water lead-out part 51f to lead the water sucked into the fan casing 52b to the water lead-out part 51f.

  According to this, after the water sucked into the fan casing 52b adheres to the inner surface of the side wall 52b4 of the fan casing 52b, the water outlet 51f and the first opening 51a are extended from the inside of the fan casing 52b through the communication water channel 50a. It is derived to the toilet bowl 2b. Therefore, even when water with odors and floating substances attached is sucked into the fan casing 52b, the odors and floating substances attached to the water can be reliably discharged together with the water to the toilet bowl 2b.

Moreover, the warm water washing toilet seat apparatus 1 is further provided with the disinfection provision part 80 which is provided between the water pipe 3 and the water ejection apparatus 53, and provides disinfection property to water.
According to this, since water having sterilizing properties can be ejected from the water ejection device 53, the amount of microorganisms such as bacteria and fungi contained in the gas sucked into the deodorizing casing 51 can be reduced. .
