The heat exchanger 51 converts the wash water supplied from the water supply source into hot water having a set temperature. Hereinafter, in the present specification, “washing water” includes water (cold water) supplied from a water supply source and hot water warmed by the heat exchanger 51.

  The heat exchanger 51 may be, for example, an instantaneous heating type (instantaneous type) heat exchanger using a ceramic heater or the like, or may be a hot water storage type heat exchanger using a hot water storage tank. The user can set the hot water temperature by operating the operation unit 44.

  The electrolytic cell 52 is provided downstream of the heat exchanger 51. The electrolytic cell 52 has a pair of electrodes, and electrolyzes wash water (tap water) flowing between the electrodes based on the energization control signal transmitted from the control unit 42. The electrolytic bath 52 generates a liquid containing hypochlorous acid (HClO) (hereinafter referred to as “functional water”) by electrolyzing chlorine ions contained in the cleaning water.

  The cleaning water that has passed through the electrolytic bath 52 and the functional water generated by the electrolytic bath 52 are sent to the cleaning nozzle 34 via the electromagnetic pump 54. The electromagnetic pump 54 pulsates the cleaning water supplied to the cleaning nozzle 34, for example.

  The cleaning nozzle 34 has a water discharge part 35. The water discharger 35 includes, for example, a butt cleaning water discharge hole 35a, a butt soft water discharge hole 35b, and a bidet cleaning water discharge hole 35c.

The bidet cleaning channel FC3 and the wide bidet cleaning channel FC4 are connected to the bidet cleaning water discharge hole 35c and supply cleaning water or functional water to the bidet cleaning water discharge hole 35c. However, the water discharge holes and flow paths of the cleaning nozzle 34 are not limited to these. As described above, the number of water discharge holes may not coincide with the number of flow paths, or may be the same as the number of flow paths.

  The cleaning water or functional water sent to the cleaning nozzle 34 is discharged upward from the water discharge portion 35. The wash water discharged from the water discharge unit 35 is used for local cleaning of the user seated on the toilet seat 14. In the cleaning nozzle 34, bidet cleaning is performed by supplying cleaning water from the bidet cleaning channel FC3 to the bidet cleaning water discharge hole 35c, and cleaning water is supplied from the wide bidet cleaning channel FC4 to the bidet cleaning water discharging hole 35c. By doing so, wide bidet cleaning is performed. The functional water is used for cleaning the water discharge holes 35a to 35c and the flow paths leading to the water discharge holes 35a to 35c. As described above, the cleaning nozzle 34 includes the four flow paths FC1 to FC4 and is configured to discharge the cleaning water or the functional water supplied from each of the four flow paths FC1 to FC4.

  Between the electromagnetic pump 54 and the cleaning nozzle 34, a flow control / flow path switching valve 55 is provided. The flow control / flow path switching valve 55 determines the destination of the washing water or the functional water supplied via the electromagnetic pump 54 to the buttocks washing channel FC1, the buttocks soft channel FC2, the bidet washing channel FC3, and the wide bidet washing channel. Switch to any of FC4, nozzle cleaning chamber 36, spray nozzle 38, and deodorizing unit 40. Further, the flow control / flow path switching valve 55 changes the water discharge flow rate of the cleaning water discharged from the water discharge holes 35 a to 35 c of the cleaning nozzle 34.

  The nozzle cleaning chamber 36 has a water discharge part 36a. The nozzle cleaning chamber 36 performs cleaning of the outer surface of the cleaning nozzle 34, that is, body cleaning, by discharging cleaning water or functional water from the water discharge portion 36a.

  The spray nozzle 38 sprays cleaning water or functional water on the surface of the bowl portion 4 a of the toilet 4. The spray nozzle 38 may be provided inside the case cover 20 or may be attached to the outside of the case cover 20.

  For example, the control unit 42 sprays water droplets from the spray nozzle 38 onto the surface of the bowl portion 4a of the toilet 4 in response to detection of the user's entry by the human body detection sensor 32. That is, the control unit 42 wets the surface of the bowl 4a of the toilet 4 with water droplets before the user uses the toilet 4. Thereby, the dirt adhering to the surface of the bowl part 4a can be reduced.

  In addition, the control unit 42, for example, when the predetermined time (for example, after 90 seconds) has elapsed since the human body detection sensor 32 no longer detects the user in the toilet room, the bowl portion of the toilet 4 from the spray nozzle 38 Functional water is sprayed on the surface of 4a. That is, the control unit 42 wets the surface of the bowl portion 4a with functional water (hypochlorous acid water) after the user finishes the use of the toilet 4 with filth flowing. Thereby, it can suppress that the microbe which becomes a bad odor increases in the bowl part 4a. It is possible to prevent malodor from being released from the toilet 4.

  The deodorizing unit 40 sucks air in the toilet room. The air in the toilet room mainly refers to air outside the toilet 4 (air other than in the bowl portion 4a). The deodorizing unit 40 collects or decomposes malodorous components contained in the sucked air. The “bad odor component” is, for example, an ammonia component. The deodorizing unit 40 discharges air that has collected or decomposed malodorous components to the outside (toilet room) of the case cover 20.

  The deodorizing unit 40 includes a dust collection filter 60, a fan (air blowing unit) 61, a deodorizing filter 62, a spraying unit 63, a water receiving unit 64, an intake port 65, and an exhaust port 66.

  The fan 61 sucks air in the toilet room from the air inlet 65 and discharges the sucked air from the air outlet 66 to the toilet room. The dust collection filter 60 is provided between the air inlet 65 and the fan 61, and suppresses dust and dirt contained in the sucked air from being sent to the fan 61.

  The deodorizing filter 62 is provided between the fan 61 and the exhaust port 66. The spray part 63 is provided above the deodorizing filter 62. The spray part 63 has a solenoid valve. The spray unit 63 performs a valve opening operation based on the control of the control unit 42, and directs the cleaning water or functional water supplied from the flow control / flow path switching valve 55 from above the deodorization filter 62 to the deodorization filter 62. Spray.

  The deodorizing filter 62 has, for example, a porous structure, and retains cleaning water or functional water sprayed from the spray unit 63. The water receiver 64 is provided below the deodorizing filter 62 and receives water dropped from the deodorizing filter 62.

When the fan 61 is activated, the air in the toilet room sucked from the air inlet 65 passes through the deodorizing filter 62. When air passes through the deodorizing filter 62 in a state where the deodorizing filter 62 retains moisture, malodorous components contained in the air are taken into the moisture retained in the deodorizing filter 62. For example, ammonia (NH ₃ ) contained in the air dissolves in the moisture held in the deodorizing filter 62. Thereby, the malodorous component contained in the air can be reduced.

  Air in which malodorous components are reduced is discharged from the exhaust port 66 to the toilet room. In this way, the deodorizing unit 40 can collect or decompose malodorous components that are always present in the toilet room. Therefore, when the user enters the toilet room, the user is less likely to inhale odors due to odorous components that are permanently present in the toilet room, and can use the toilet room comfortably.

  For example, the control unit 42 stops the operation of the fan 61 in a time zone in which the user's toilet device 2 is used less frequently. And the control part 42 makes the deodorizing filter 62 hold | maintain a water | moisture content, while operating the fan 61 and operating the spray part 63 regularly in the time zone when the user's toilet device 2 is used frequently.

  Thereby, in the time zone when the user is likely to enter the toilet room, it is possible to remove the odor that is always present in the toilet room. Therefore, it is possible to suppress the user from feeling uncomfortable by sucking the odor that is always present in the toilet room.

The movable disk 82 slides and rotates on the front surface 80a about a direction orthogonal to the front surface 80a as an axis (hereinafter referred to as a rotation axis RA). The movable disk 82 has an opening corresponding to one port of the fixed disk 80. For example, when the opening of the movable disk 82 overlaps with one port of the fixed disk 80, another port of the fixed disk 80 is blocked by the movable disk 82. Thereby, water can be passed through only one port that overlaps the opening of the movable disk 82.

Can do. In the fixed disk 80 and the movable disk 82, in the movable range MR of the movable disk 82, the state in which water is simultaneously passed through the flow paths FC1 to FC4 can be made only once.

Next, operation | movement of the sanitary washing apparatus 10 which concerns on this embodiment is demonstrated.
When the human body detection sensor 32 detects the user entering the toilet room, the control unit 42 of the sanitary washing device 10 sets the movable disk 82 to the state shown in FIG. Water droplets are sprayed on the surface of the portion 4a. Thereby, the dirt adhering to the surface of the bowl part 4a can be reduced.

  The sanitary washing device 10 performs the warm water preparation operation before starting the washing of the user's body (main washing). The warm water preparation includes a first warm water preparation process and a second warm water preparation process.

When receiving the instruction of the local cleaning operation from the operation unit 44, the control unit 42 executes the first warm water preparation process.
The first warm water preparation step includes a “pre-cleaning” step and a “body cleaning” step.

  In “pre-cleaning”, the control unit 42 controls the flow path opening / closing valve 50 and the flow control / flow path switching valve 55 so that the movable disk 82 is in the state shown in FIG. Water is discharged from the water discharge holes 35a to 35c. Thereby, the water in each of the flow paths FC <b> 1 to FC <b> 4 between the heat exchanger 51 and the cleaning nozzle 34 is replaced with warm water heated by the heat exchanger 51.

  During the pre-cleaning operation, the cleaning nozzle 34 is in a standby state in which it is retracted into the case cover 20. Therefore, the water discharged from the water discharge unit 35 is reflected by, for example, the inner surface of the nozzle cleaning chamber 36 and is applied to the outer peripheral surface of the cleaning nozzle 34 and the water discharge unit 35. Thereby, the outer peripheral surface of the cleaning nozzle 34 and the water discharge portion 35 are cleaned by the water discharged by the cleaning nozzle 34 itself and reflected by the inner surface of the nozzle cleaning chamber 36 (self-cleaning).

  In “body cleaning”, the control unit 42 controls the flow path opening / closing valve 50 and the flow control / flow path switching valve 55 so that the movable disk 82 is in the state shown in FIG. 7C or FIG. Thus, water is ejected from the water discharge portion 36 a provided in the nozzle cleaning chamber 36. Thereby, the outer peripheral surface of the cleaning nozzle 473 can be cleaned. For example, when the bidet cleaning or the wide bidet cleaning is instructed, the control unit 42 brings the movable disk 82 into the state shown in FIG. 7C, and when the buttocks cleaning or the buttocks soft cleaning is instructed, the movable disk 82 is set. Is the state shown in FIG.

  The control unit 42 controls a nozzle motor (not shown) to move the cleaning nozzle 34 into the bowl 4 a of the toilet 4. The control unit 42 cleans the outer peripheral surface of the cleaning nozzle 34 by ejecting water from the water discharge unit 36 a of the nozzle cleaning chamber 36 when the cleaning nozzle 34 advances.

  Thus, the control part 42 performs the 1st warm water preparation process, and makes the temperature of the water inside each flow path FC1-FC4 between the heat exchanger 51 and the washing nozzle 34 the heat exchanger 51. Thus, the temperature can be raised to a specified temperature. Thereafter, the control unit 42 controls the flow control / flow path switching valve 55 to pass water through one of the flow paths FC1 to FC4 for local cleaning based on an instruction from the user. When the movable disk 82 is rotated from the position corresponding to the nozzle cleaning chamber 36 to the positions of the flow paths FC1 to FC4, the flow rate can be gradually increased by the adjustment grooves 131 to 134.

For example, when the seating detection sensor 31 detects a user seated on the toilet seat 14, the control unit 42 executes the second hot water preparation step before executing the first hot water preparation step.
The second warm water preparation step includes a “water removal” step.
The trigger for starting the second warm water preparation step is not limited to the seating detection sensor 31 detecting the user, and the human body detection sensor 32 or the entrance detection sensor may detect the user. Good.

  In “water draining”, the control unit 42 controls the flow path opening / closing valve 50 and the flow control / flow path switching valve 55 to bring the movable disk 82 into the state shown in FIG. Water is discharged from the water discharge holes 35a to 35c. Thereby, the water inside the flow path is discharged to the bowl portion 4 a of the toilet 4.

  Thus, the control part 42 starts the water supply to the inside of a flow path by performing a 2nd warm water preparation process, and discharges the water remaining inside the flow path to the bowl part 4a of the toilet 4 To do. Note that the second warm water preparation step is not necessarily executed.

Further, by providing an intermediate position MP for simultaneously passing water through the first port 101 to the fourth port 104 on the side opposite to the regulation range BR, the first port 101 to the fourth port in the movable range MR of the movable disk 82. The state where water is simultaneously passed through 104 can be made only once. Thereby, supply of washing water or functional water to an unintended channel can be controlled and controllability can be improved. Therefore, it is possible to provide the sanitary washing apparatus 10 that can suppress the increase in size of the fixed disk 80 and the movable disk 82 and can obtain good controllability while accommodating the diversification of the washing modes.

  In the sanitary washing device 10, the second auxiliary port 112 is provided on the opposite side of the first auxiliary port 111 across the center of the first circumference C1. Thereby, the 1st auxiliary port 111 and the 2nd auxiliary port 112 can be arranged efficiently. The movable range MR of the movable disk 82 can be expanded, and the increase in size of the fixed disk 80 and the movable disk 82 can be further suppressed.

  In the sanitary washing device 10, the third virtual line VL3 connecting the first opening 151 and the center of the first circumference C1 is the fourth virtual line VL4 connecting the second opening 152 and the third opening 153. Orthogonal to Thereby, the 2nd opening part 152 and the 3rd opening part 153 can be arrange | positioned efficiently, and the enlargement of the fixed disk 80 and the movable disk 82 can be suppressed more.
