And is decomposed and removed by the catalytic action of the deodorizing material. As the deodorizing material used for the deodorizing body unit 252, a known material mainly composed of silica, alumina, carbon or the like is used. These deodorizing materials can decompose and remove hydrogen sulfide (a main odor component of egg odor) and methyl mercaptan (a main odor component of spoiled odor such as onion and cabbage), which are typical odor components, by catalytic action.

  A basic deodorizing operation by the deodorizing unit 25 having the above-described configuration will be described. First, when the user sits on the toilet seat 15, the seating sensor 271 detects the seating and outputs a detection signal to the control unit 27 (broken arrow in FIG. 3). In response to the seating detection signal, the control unit 27 starts the operation of the deodorizing blower 253 of the deodorizing unit 25, and causes the air in the toilet 50 to enter the deodorizing air passage 255 from the deodorizing intake port 254a as indicated by the block arrow F2. Suction. The sucked air passes through the deodorizing body unit 252 as shown by the block arrow F2, is sucked into the deodorizing blower 253, and then discharged toward the exhaust port 254b. From the exhaust port 254b to the block arrow F2 As shown, the air is exhausted outside the body 12.

  Since the odor component in the sucked air is decomposed and removed by the deodorizing unit 252 as described above, the odor component is removed from the air after passing through the deodorizing unit 252. Therefore, the air discharged from the exhaust port 254b into the toilet room is almost odorless.

  Thereafter, when the user finishes the stool and stands up from the toilet seat 15, the seating sensor 271 detects the end of the user's seating (separation) and outputs a detection signal to the control unit 27 (the broken line in FIG. 3). Arrow). The controller 27 stops the operation of the deodorizing blower 253 after a predetermined time (for example, 1 minute) set in advance is received in response to the detection signal of the sitting. Thereby, since most of the odor components generated in the toilet 50 in the toilet can be removed by the deodorization unit 25, it is possible to effectively suppress the possibility that the odor is diffused throughout the toilet room. it can.

  The opening / closing part 26 opens and closes the toilet lid 14 and the toilet seat 15 as described above. In the present embodiment, for example, the driving motor and the rotational driving force from the driving motor are used to rotate the toilet lid 14 and the toilet seat 15. A power transmission mechanism for transmitting to one of the shafts to open / close them, an opening / closing drive circuit for driving the drive motor based on a control signal from the control unit 27, and at least an opening / closing position of the toilet lid 14 (preferably the toilet lid 14 and An opening / closing position sensor 261 and the like for detecting the opening / closing position of the toilet seat 15 are provided.

  The opening / closing operation of the toilet lid 14 and the toilet seat 15 by the opening / closing unit 26 is controlled by the control unit 27 (broken arrows in the figure). The open / close position sensor 261 detects the open / close position of the toilet lid 14 (and the toilet seat 15) and outputs a detection signal to the control unit 27. The open / close detection signal is used for operation control of the electrostatic atomizer 31 and the like, as will be described later. In the present embodiment, the open / close position sensor 261 is a sensor that detects the rotational position of the rotational axis of the toilet lid 14 (and the toilet seat 15), but may be another known sensor. In FIG. 3, the opening / closing of the toilet lid 14 and the toilet seat 15 by the opening / closing part 26 is indicated by a thick arrow, and is distinguished from a broken arrow indicating input / output of a control signal.

  The control unit 27 outputs an operation signal from the remote controller 16 or the main body side operation unit 32, a human body detection sensor 17, a seating sensor 271, a humidity sensor 313, an open / close position sensor 261, a flow rate sensor 237 of the cleaning water supply unit 23, or the like. Based on the detected signal or the like, the operation of the above-described cleaning mechanism, drying unit 24 and deodorizing unit 25, electrostatic atomizing unit 31 to be described later, and the like are controlled. As shown in FIG. In the form, it is provided behind the drying unit 24. In the present embodiment, the control unit 27 is configured as a circuit board in which a known arithmetic unit and various elements are mounted on the board.

  Moreover, in order to measure the predetermined time preset in control of the control part 27, as shown in FIG. 3, the time measuring part 272 is provided. The predetermined time measured by the timing unit 272 is “deodorization operation stop time” from when the human body detection sensor 17 stops detecting the human body until the operation of the deodorization unit 25 is started and stopped, or the deodorization unit 25 Examples include “electrostatic atomization operation stop time” from when the operation is stopped to when the operation of the electrostatic atomization unit 31 is started and stopped.

  The specific configuration of the timer unit 272 is not particularly limited, and a known timer circuit or clock circuit may be suitably used, and a function realized by an arithmetic unit constituting the control unit 27 operating according to a program. It may be a configuration. The timer circuit or the clock circuit may be mounted on the single substrate together with the control unit 27. Therefore, the time measuring unit 272 may be included in the control unit 27.

  Moreover, the remote controller 16 and the main body side operation unit 32 may include humidification abnormality notification units 163 and 323, respectively, as shown in FIG. As the humidification abnormality notification units 163 and 323, the display units 162 and 323 included in the remote controller 16 and the main body side operation unit 32 may be used, or a display unit different from the display units 162 and 323 is provided. Alternatively, the configuration may be such that the abnormality is notified by voice instead of display. The humidification abnormality notification units 163 and 323 are not provided in both the remote controller 16 and the main body side operation unit 32, and may be provided in only one of them.

  Specific configurations of the cleaning nozzle unit 21, the heat exchange unit 22, the cleaning water supply unit 23, the drying unit 24, the deodorizing unit 25, the control unit 27, and the like having the above-described configuration are not particularly limited, and are known in the technical field of the present invention. The configuration can be suitably used. In addition, a functional unit other than these may be built in the main body 12.

[Configuration of electrostatic atomizer]
Next, the electrostatic atomizer 31 in the functional unit will be specifically described with reference to FIGS. 1 to 3 and FIGS. 5 to 7. FIG. 5 is a side view showing an example of the internal configuration of the sleeve 13, but the sleeve 13 is located on the right side of the main body 12, and therefore corresponds to an internal plan view when the main body 12 is viewed from the right side. .

  2 and 5, the electrostatic atomizer 31 is accommodated in the sleeve 13, and as shown in FIG. 6, the electrostatic atomizer 31 includes an electrostatic atomizer 330, a fog The gasification part casing 311, the atomization part air blower 312, the humidity sensor 313, the louver 314, etc. are provided.

  As shown in FIG. 6, the atomizing section casing 311 is a hollow casing, and includes an atomizing section blower 312, a humidity sensor 313, and an electrostatic atomizer 330. The inside of the atomization part casing 311 has a fan space 311a for accommodating the atomization part blower 312; an electrostatic atomization space 311b for accommodating the electrostatic atomizer 330; and a duct communicating with the discharge port 311d. It is partitioned into a space 311c. Of these three paces, the electrostatic atomization space 311b and the duct space 311c constitute an atomization section air passage 315 through which an air flow (wind) sent from the atomization section blower 312 flows.

  The blower space 311a is located on the most upstream side of the air flow in the atomizing section casing 311 and the atomizing section blower 312 is provided therein as described above. The atomizer blower 312 sucks the air in the main body 12 as indicated by the block arrow F1 in FIG. 2, and the electrostatic atomization space 311b (the atomizer air path 315) as indicated by the block arrow F3 in FIG. An air flow is generated toward In the present embodiment, a sirocco fan is used as the atomizing section blower 312. The atomizer blower 312 has a blower inlet 312a for sucking air as shown in FIGS. 5 and 6, and sends out the sucked air as an air flow as shown in FIG. It has an air outlet 312b.

  The blower intake port 312a is provided in a circular shape coaxially with the rotation center of the atomizer blower 312 and is not covered by the atomizer casing 311 on the side surface of the electrostatic atomizer 31 as shown in FIG. Exposed. In a state where the electrostatic atomizer 31 is housed in the sleeve 13 (main body 12), the blower air inlet 312a is located inside the main body 12, not outside the main body 12. Therefore, the air sucked from the blower inlet 312a is the air of the main body 12. As will be described later, the air in the main body 12 is mainly air in the toilet 50 that flows in from a gap provided in the bottom plate or the like of the main body 12.

  The electrostatic atomization space 311b is located adjacent to the front of the blower space 311a and is isolated from the blower space 311a except for the blower port 312b of the atomization unit blower 312. In the electrostatic atomization space 311b, an electrostatic atomizer 330 is provided at the center, and a humidity sensor 313 is provided below the electrostatic atomizer 330 and in the vicinity of the air blowing port 312b. Therefore, the electrostatic atomization space 311b is not a space in which an air flow flows, but a space that can accommodate the electrostatic atomizer 330 and the humidity sensor 313.

  The duct space 311c has one end communicating with the front lower part of the electrostatic atomization space 311b and the other end communicating with the outside of the sleeve body 13 as a discharge port 311d. Further, as shown in FIGS. 1 and 5, since the discharge port 311d is located below the front surface of the sleeve body 13, as shown in FIG. 6, the vicinity of the discharge port 311d of the duct space 311c is the sleeve body. It is bent so that it goes to 13 front. Therefore, the duct space 311c has a shape bent in an L shape toward the lower side when viewed from the upstream side.

A louver 314 is attached to the discharge port 311d. The louver 314 functions as a wind direction adjusting member that deflects the direction of the air flow discharged from the discharge port 311d and guides it in a desired direction, and also functions as a member for avoiding foreign matter from entering the discharge port 311d. To do.
The electrostatic atomizer 330 generates charged fine particle water by an electrostatic atomization phenomenon, and includes a condensed water generation unit 331, an atomization electrode 332, and a counter electrode 333 as shown in FIG. . The condensed water generating unit 331 generates liquid water (condensed water) by condensing moisture (water vapor) in the air, and includes at least a Peltier element 334 and radiating fins 335. In the electrostatic atomization phenomenon, an atomization electrode 332 (discharge electrode) is provided on the cooling side of the Peltier element 334, a high voltage is applied to the water condensed on the tip of the atomization electrode 332, and static electricity between the counter electrode 333 and This is a phenomenon in which charged fine particle water is released by force. The charged fine particle water generated by the electrostatic atomization phenomenon has a deodorizing action and a sterilizing action.

  The Peltier element 334 includes a cooling substrate 334a and a heat dissipation substrate 334b, and a lead wire 334c is connected thereto. The lead wire 334c is provided with a connector 334d, and is electrically connected to the control unit 27 shown in FIG. 2 via the connector 334d. In the present embodiment, a DC voltage, for example, a voltage that exceeds 0V and becomes 1V or less is applied to the Peltier element 334. The heat radiating fins 335 are connected to the heat radiating substrate 334b of the Peltier element 334, and are made of a metal such as aluminum.

  The atomization electrode 332 is an electrode for applying a voltage to the water generated by the condensed water generation unit 331, and has a shape in which the lower tip is pointed. The other upper end of the atomizing electrode 332 is connected to the cooling substrate 334 a of the Peltier element 334, and the lower end is directed to the counter electrode 333. In the atomizing electrode 332, water condensed on the cooling substrate 334 a of the Peltier element 334 flows down toward the tip of the atomizing electrode 332.

  The counter electrode 333 is provided at a position facing the atomizing electrode 332 and has a substantially dome shape surrounding the tip of the atomizing electrode 332. The atomizing electrode 332 and the counter electrode 333 are respectively provided with an atomizing electrode connection terminal 332a and a counter electrode connection terminal 333a for energization, and are electrically connected to the control unit 27 via these connection terminals 332a and 333a. It is connected to the. A high direct current voltage, for example, about 3500 V is applied between the atomizing electrode 332 and the counter electrode 333.

  As described above, the electrostatic atomizer 31 in the present embodiment has the electrostatic atomizer 330 and the humidity sensor 313 in the atomizer air path 315 (more specifically, the electrostatic atomization space 311b). Although it is located, the charged fine particle water generated by the electrostatic atomizer 330 can be quickly discharged outside the main body 12 (in the toilet room), and the electrostatic atomizer 330 is installed. Since the humidity of the space (the atomizing section air passage 315) can be detected by the humidity sensor 313, the humidifying operation described later can be controlled well.

  Moreover, if the electrostatic atomizer 330 is located in the center part of the atomization part air path 315, there also exists an advantage that the circulating airflow demonstrated below can be formed. Further, the inside of the main body 12 and the sleeve body 13 communicates with the inside of the toilet bowl 50, and the inside of the electrostatic atomizer 31 communicates with the inside of the main body 12 via the blower air inlet 312a. Is provided in the atomizing section air passage 315, the humidity in the toilet 50 can be substantially detected.

  Next, a basic operation in the electrostatic atomizer 31 having the above-described configuration will be described. First, energization of the atomizer blower 312 and the electrostatic atomizer 330 is started as the control unit 27 starts the operation of the electrostatic atomizer 31 based on predetermined setting conditions. As shown by a block arrow F1 in FIG. 2, the atomizing section blower 312 sucks air from the inside of the main body 12 through the blower intake port 312a, and electrostatically flows from the blower port 312b as shown by a block arrow F3 in FIG. An air flow is sent out toward the atomization space 311b.

  Here, as described above, an opening is provided for advancing and retracting the first cleaning nozzle 211 and the like of the cleaning nozzle portion 21, and drainage for draining excess water leaking from the water supply system in other areas as well. Since the mouth and the like are provided, the inside of the main body 12 communicates with the toilet 50 through these openings. Therefore, the air in the main body 12 is a lot of moisture sucked from the toilet 50.

  The air flow sent to the electrostatic atomization space 311 b passes through the lower part of the electrostatic atomizer 330. In the lower part of the electrostatic atomizer 330, as shown in FIG. 7, the Peltier element 334, the atomization electrode 332, and the counter electrode 333 of the condensed water generation unit 331 are positioned. In particular, the air is blown toward the cooling substrate 334 a and the atomizing electrode 332 of the Peltier element 334 and the low temperature portion of the counter electrode 333. Most of the airflow that has passed through the lower part of the electrostatic atomizer 330 passes through the duct space 311c and is outside the sleeve 13 from the discharge port 311d (in the toilet room), as indicated by a block arrow F31 in FIG. To be released.

  Here, a part of the air flow that has passed through the lower part of the electrostatic atomizer 330 collides with the front inner surface of the electrostatic atomization space 311b and rises as shown by a block arrow F32 in FIG. It passes through the upper part of the atomizer 330 and returns to the vicinity of the air outlet 312b of the atomizer blower 312. Accordingly, a part of the air flow becomes a circulating air flow circulating in the electrostatic atomization space 311b. Since the heat radiating fins 335 are located at the upper part of the electrostatic atomizer 330, the circulating air flow is heated by absorbing heat radiated from the heat radiating fins 335 and flows again in the direction of the block arrow F3.

  In the electrostatic atomizer 330, when the air flow contacts the cooling substrate 334 a of the Peltier element 334, moisture in the air condenses on the cooling substrate 334 a to generate condensed water. The condensed water flows down from the cooling substrate 334 a to the tip side of the atomizing electrode 332. Since the electrostatic atomizer 330 is energized, a high voltage is applied between the atomizing electrode 332 and the counter electrode 333 as described above. Therefore, Rayleigh splitting occurs in the dew condensation water, thereby generating nanometer-sized charged fine particle water. In addition, since the temperature difference between the cooling substrate 334a of the Peltier element 334 and the atomization electrode 332 and the low temperature portion of the counter electrode 333 is expanded by the circulating air flow, dew condensation on the cooling substrate 334a (and the atomization electrode 332) is improved. Thus, charged fine particle water can be generated more efficiently.

  Thus, since the charged fine particle water is contained in the air flow (the air flow indicated by the block arrow F31) that has passed through the lower part of the electrostatic atomizer 330, the charged fine particle water enters the toilet room from the discharge port 311d. An air stream containing is released. The discharged charged fine particle water scatters in the toilet room and adheres to the odor component floating in the toilet room or the wall surface, ceiling surface, floor surface, or the like of the toilet room.

  Since the diameter of the nanometer-sized charged fine particle water is very small, it is possible to effectively enter the fine irregularities present on the wall surface, ceiling surface, or floor surface. Therefore, it is possible to deodorize odor components adhering to the wall surface or to disinfect fungi. Particularly for deodorization, the charged fine particle water can decompose and remove odor components such as ammonia, acetaldehyde, acetic acid, methane, carbon monoxide, nitrogen monoxide, formaldehyde, etc. Can be deodorized satisfactorily.

  Note that the atomizer blower 312 is a sirocco fan in the present embodiment, but is known as long as it generates an air flow for discharging charged fine particle water generated by the electrostatic atomizer 330 to the outside. Other air blowing means can be used. Further, the discharge port 311d is provided in the lower part of the front surface of the sleeve body 13, but is not limited to this position. The discharge port 311d has the generated charged fine particle water outside the main body 12 (sleeve body 13) and outside the toilet 50. Other positions may be used as long as they can be released.

  Furthermore, in this Embodiment, although the atomization part air path 315 is comprised by the electrostatic atomization space 311b and the duct space 311c, the atomization part air path 315 is not limited to this, Other space is included. However, it may not be clearly divided into the electrostatic atomization space 311b and the duct space 311c. Or if the airflow formed with the atomization part air blower 312 is discharge | released favorably from the discharge port 311d, the air blower space 311a and the atomization part air path 315 (especially electrostatic atomization space 311b) will be distinguished. There may be no partition.

  Moreover, in this Embodiment, although the circulating air flow (refer block arrow F32 of FIG. 6) mentioned above is produced | generated because the electrostatic atomizer 330 is located in the center part of the electrostatic atomization space 311b, The atomizer 330 may not be located in the electrostatic atomization space 311b so that a circulating air flow is formed. The electrostatic atomizer 330 should just be located in the atomization part air path 315, and the specific structure of the atomization part air path 315 is specified in the division | segmentation into three spaces as shown in FIG. Not. In addition, the humidity sensor 313 may be provided in the atomizing air passage 315 or may be provided on the main body side in the vicinity of the blower air inlet 312 a that sucks air into the atomizing air passage 315.

[Normal operation and humidification operation of sanitary washing equipment]
Next, in the sanitary washing apparatus 10 having the above-described configuration, a normal operation at the time of use and a humidifying operation for efficiently generating charged fine particle water by the electrostatic atomizing unit 31 will be described with reference to FIGS. ), (B), FIG. 9 and FIG.

  First, the normal operation of the sanitary washing device 10 will be described. When the user enters the toilet room and the human body detection sensor 17 detects the human body, the control is performed by the detection signal from the human body detection sensor 17 as shown in FIG. The unit 27 operates the opening / closing unit 26 to open the toilet lid 14 (not shown in FIG. 3), and starts energizing the toilet seat heater (not shown in FIG. 3) in the toilet seat 15 to The temperature is raised in a short time (for example, within 10 seconds) so that the seating surface has a temperature suitable for seating (for example, about 40 ° C.).

  Next, when the user sits on the toilet seat 15, the seating sensor 271 detects the seating, and the control unit 27 performs a deodorizing operation by the deodorizing unit 25 (not shown in FIG. 3) based on the detection signal from the seating sensor 271. Let it begin. In addition, the control unit 27 receives a seating detection signal and permits a cleaning operation by the main body side operation unit 32 and the remote controller 16 of the main body 12. The deodorization unit 25 continues the deodorization operation during the cleaning operation of the user's stool and the cleaning nozzle unit 21 after the stool, but the user leaves the toilet seat 15 and leaves the toilet room, and the human body detection sensor 17 After the human body is no longer detected (after the user leaves the toilet room), the deodorization operation is stopped after a predetermined time (deodorization operation stop time) has elapsed.

  If the deodorizing operation of the deodorizing unit 25 stops after the user leaves the room, the control unit 27 starts the electrostatic atomizing operation by the electrostatic atomizing unit 31, and the predetermined time (electrostatic atomizing operation stop time). After elapses, the electrostatic atomization operation is stopped. The control unit 27 stops the operation of the electrostatic atomization unit 31 when the user enters the toilet room during the operation of the electrostatic atomization unit 31 (when the human body detection sensor 17 detects the human body). . Further, in the case of a boy's small person who does not sit on the toilet seat 15, the control unit 27 does not operate the deodorizing unit 25, but after the user leaves the toilet room (the human body detection sensor 17 detects the human body). After that, the control unit 27 starts the operation of the electrostatic atomization unit 31 and stops it after a predetermined time (electrostatic atomization operation stop time) has elapsed as described above.

  Here, even if the electrostatic atomizer 31 operates, charged fine particle water may not be generated depending on the environment of the toilet room. Specifically, if the lower limit humidity at which charged fine particle water is generated with respect to temperature is defined as “lower limit humidity”, the temperature is about 24 to 25 ° C. (about 25 ° C.) as shown in FIG. If it is more than that, the “lower limit humidity” is approximately 20%. Therefore, even if the temperature is about 25 ° C. or higher, if the humidity is less than about 20%, the electrostatic atomizer 31 cannot generate charged fine particle water. In other words, if the humidity of the toilet room is 20% or higher and the temperature is about 25 ° C. or higher, the electrostatic atomizer 31 can generate charged fine particle water.

  However, when the temperature falls below about 25 ° C., the “lower limit humidity” gradually increases from 20%, and when the temperature of the toilet room reaches approximately 1 ° C., the “lower limit humidity” also reaches approximately 85%. Therefore, when the temperature is lower than when the temperature is relatively high, the electrostatic atomizing unit 31 cannot generate charged fine particle water unless the humidity is relatively high. Moreover, if the temperature of a toilet room is less than 1 degreeC, even if humidity is 85% or more, the electrostatic atomization part 31 cannot generate charged fine particle water.

  In the summer, the temperature of the toilet room tends to increase. Therefore, even if the humidity is somewhat low, the electrostatic atomization unit 31 can generate charged fine particle water if the humidity is 20% or more. On the other hand, in winter, the temperature of the toilet room may be lowered to a single-digit temperature (° C.). Therefore, if the humidity is not high, the electrostatic atomizer 31 generates charged fine particle water. I can't.

  Therefore, the sanitary washing device 10 according to the present embodiment has a predetermined humidity (predetermined value), for example, preset by a humidity sensor 313 provided in the electrostatic atomizer 31 as shown in FIG. If it is detected that it is 85% or less, the control unit 27 operates the opening / closing unit 26 to close the toilet lid 14, and then discharges warm water into the toilet 50 by the washing nozzle unit 21. It is comprised so that the humidification operation | movement which operates the electroatomization part 31 may be performed. Thereby, even when the humidity falls below a predetermined value while the electrostatic atomizer 31 is operated, charged fine particle water can be generated satisfactorily.

  As described above, the inside of the toilet bowl 50 and the inside of the main body 12 communicate with each other. Usually, since flush water exists in the toilet bowl 50, the humidity is relatively higher than the outside of the toilet bowl 50 (toilet room). Tend to be high. And if the state which closed the toilet lid 14 and the toilet bowl 50 inside is formed, and warm water is discharged from the washing nozzle part 21, the humidity in the toilet bowl 50 can be raised favorably. At this time, cleaning water that is not heated may be discharged, but by discharging the cleaning water heated by the heat exchanging unit 22 (that is, hot water), the humidity in the toilet 50 can be increased more favorably. .

  In the example shown in FIG. 8A, when the electrostatic atomizer 31 starts an electrostatic atomization operation at time t1 (ON in the figure), the humidity detected by the humidity sensor 313 exceeds 85%. However, when the humidity gradually decreases and the time t2 is reached, the humidity starts to drop below 85%, so the control unit 27 starts the humidification operation with the humidity 85% as a predetermined value (threshold) (" Implementation "block arrow). Thereafter, the humidity is recovered to 85% when the humidification operation is continued and time t3 is reached, so the control unit 27 stops the humidification operation, and then the humidity falls below 85% when time t4 is reached. Since it started, the control unit 27 starts the humidification operation, and when the time t5 is reached, the electrostatic atomization operation of the electrostatic atomization unit 31 is stopped. Therefore, even if the humidity does not recover to 85%, the control unit 27 Humidification operation is interrupted.

  The predetermined value of the humidity for determining whether or not to start the humidifying operation is not limited to the above-described 85%, and the usage environment or usage method of the sanitary washing device 10 or the specific value of the sanitary washing device 10 A preferable value can be set as appropriate according to various conditions such as various configurations. For example, if the temperature of the toilet room is assumed not to be 5 ° C. or lower even in winter, the predetermined value may be set to 60 to 70% from the graph shown in FIG.

  The humidification operation will be described more specifically. First, as shown in the lower view of FIG. 9, a general toilet 50 is provided with a water storage tank 51 on the rear side, and water discharged from the water storage tank 51 after a stool flows through the toilet 50 and is drained. Drained into the pipe 52. Here, normally, in the toilet bowl 50, all the water does not flow out to the drain pipe 52, and the accumulated water 60 remains. Therefore, in the state where the toilet lid 14 is closed, the inside of the toilet 50 is substantially isolated from the outside (toilet room), and therefore, the humidity tends to be relatively higher than that of the outside.

  9, the inside of the main body 12 and the sleeve body 13 communicates with the toilet 50 through an opening such as a gap 12a provided in the main body 12, for example. Therefore, if the atomizer blower 312 (see FIGS. 5 and 6) of the electrostatic atomizer 31 is operated, the block arrow F5 is directed from the gap 12a toward the fan inlet 312a of the electrostatic atomizer 31. As shown schematically, an air flow is formed. Therefore, the air in the toilet bowl 50 can be supplied to the electrostatic atomizer 31. However, when the temperature is low, such as in winter, the temperature or humidity in the toilet 50 may not reach a level at which the electrostatic atomizing unit 31 can generate charged fine particle water.

  Therefore, the control unit 27 causes hot water to be discharged from the washing nozzle unit 21 into the toilet 50 with the toilet lid 14 closed, as indicated by the block arrow D, with the toilet lid 14 closed. By performing this humidification operation, the humidity in the toilet bowl 50 (and the temperature in the toilet bowl 50 depending on the conditions) can be increased in a state where the inside of the toilet bowl 50 where humidity tends to be high is isolated from the outside. Therefore, the electrostatic atomizer 31 can generate charged fine particle water satisfactorily using the high-humidity air in the toilet 50, and discharges the generated charged fine particle water from the discharge port 311d to the toilet room. (Block arrow F4).

  9 is a schematic cross-sectional view in the horizontal direction of the main body 12, and the lower view in FIG. 9 is a schematic cross-sectional view in the vertical direction of the main body 12 including the toilet 50 corresponding to the upper view. Further, the gap 12a of the main body 12 shown in the upper view of FIG. 9 and the block arrow F5 showing the air flow from the toilet 50 toward the blower inlet 312a are schematically shown for explaining the humidifying operation. . For example, the gap 12 a may be provided in the vicinity of the cleaning nozzle portion 21, may be provided in a slit shape between the upper cover of the main body 12 and the bottom plate, or may be provided with a plurality of through holes on the bottom plate side of the main body 12. You may provide as.

  Here, the temperature of the hot water discharged from the cleaning nozzle unit 21 may be a temperature (humidification value) higher than the reference value when the temperature of the hot water set for human body cleaning is used as a reference value. preferable. If the temperature of the hot water is a higher humidification value, the humidity in the toilet 50 can be increased more efficiently than when the reference value of hot water is discharged.

  The reference value of warm water should just be equal to or higher than a known temperature set for warm water (cleaning warm water) for performing human body cleaning, for example, a temperature of about 40 to 60 ° C. it can. Since the reference value and the humidification value can be appropriately set according to the temperature of the toilet room, specific values are not particularly limited. The control part 27 should just be comprised so that the temperature of the warm water produced | generated at the time of humidification operation | movement may control the heating operation of the heat exchange part 22 so that it may become a humidification value higher than a reference value. Therefore, for example, in summer, the heat exchange unit 22 may be controlled so that the reference value and the humidification value are lower than those in winter.

  The actual measured value of the humidity detected by the humidity sensor 313 is the humidity in the electrostatic atomization unit 31, and the inside of the electrostatic atomization unit 31 communicates with the sleeve 13 through the air blower inlet 312a. Therefore, the humidity in the sleeve 13 (that is, in the main body 12) is detected. 9, since the sleeve 13 and the main body 12 communicate with the toilet 50 through the gap 12a, the humidity detected by the humidity sensor 313 is within the toilet 50. It can be regarded as humidity.

  Therefore, the control unit 27 may control the discharge operation of the hot water into the toilet bowl 50 by the cleaning nozzle unit 21 according to the actually measured humidity value detected by the humidity sensor 313. For example, the amount of hot water discharged from the cleaning nozzle unit 21 may be changed according to a change in the actual measured value of humidity by the humidity sensor 313, or the first cleaning nozzle 211 or the second cleaning may be performed according to the actual measured value of humidity. The nozzle 212 or both may be advanced from the main body 12 and the hot water may be discharged so as to diffuse the hot water into the toilet bowl 50. Of course, until the measured humidity value detected by the humidity sensor 313 recovers 85%, the same amount of hot water is discharged without moving the first cleaning nozzle 211 or the second cleaning nozzle 212 forward or backward. You may perform uniformly, without changing discharge of warm water in between.

  Further, the member that discharges hot water in the cleaning nozzle unit 21 may be the first cleaning nozzle 211 or the second cleaning nozzle 212 (see FIG. 3), but is not limited to these human body cleaning nozzles, and the nozzle cleaning unit 213 ( (See FIG. 3). If the humidity sensor 313 detects that the humidity is equal to or less than a predetermined value (for example, 85%), the control unit 27 may perform a humidification operation by discharging hot water from the nozzle cleaning unit 213.

  Furthermore, the configuration for discharging hot water into the toilet bowl 50 may be a configuration other than the cleaning nozzle portion 21. That is, the main body 12 only needs to be provided with a water discharge section that discharges the hot water heated by the heat exchange section 22. For example, in addition to the cleaning nozzle section 21, the water discharge branched from the hot water pipe 200 a shown in FIG. 3. A part may be provided separately.

  Next, a specific example of the control of the electrostatic atomizer 31 by the controller 27 described above will be specifically described with reference to FIG. First, the control unit 27 determines whether or not the operation of the electrostatic atomizer 31 has been started (step S101). That is, after the user leaves the room and the operation of the deodorization unit 25 starts, a predetermined time (deodorization operation stop time) elapses, the operation of the deodorization unit 25 stops and the operation of the electrostatic atomization unit 31 starts. It is determined whether or not. If it has not been started (NO in step S101), the determination is repeated. If it has been started (YES in step S101), it is determined whether or not the actual humidity value detected by the humidity sensor 313 is equal to or less than a predetermined value. (Step S102).

  If the humidity is not lower than the predetermined value (NO in step S102), the control unit 27 repeats the determination. If the humidity is lower than the predetermined value (YES in step S102), the toilet lid 14 is opened from the detection result of the opening / closing position sensor 261. It is determined whether or not (step S103). If the toilet lid 14 is open (YES in step S103), the control unit 27 operates the opening / closing unit 26 to close the toilet lid 14 (step S104).

  In a state where the toilet lid 14 is closed (NO in step S103 or after execution of step S104), the control unit 27 causes the heat exchange unit 22 to generate hot water that is equal to or higher than a reference value, and a water discharge unit, for example, a first washing nozzle The hot water is discharged from 211 (step S105). Thereafter, it is determined whether or not the actual measured value of humidity by the humidity sensor 313 is equal to or greater than a predetermined value (step S106). If the predetermined value has not been reached (NO in step S106), the discharge of warm water is continued (return to step S105), but if the predetermined value or more is reached (YES in step S106), the control unit 27 is electrostatically charged. It is determined whether or not the operation of the atomizing unit 31 has been completed (step S107).

  As described above, since the electrostatic atomization unit 31 stops after the predetermined time (electrostatic atomization operation stop time) has elapsed, if the predetermined time has not elapsed (NO in step S107), the control unit 27 is stopped. The humidity sensor 313 detects the actual measured value of humidity and checks whether it is equal to or less than a predetermined value (return to step S102). If it is below the predetermined value, the control operation described above is repeated (steps S103 to S106). If the predetermined time has elapsed, the operation of the electrostatic atomizer 31 is completed (YES in step S107), and thus a series of controls are terminated.

  In the example of control shown in FIG. 10, the control unit 27 checks the humidity by the humidity sensor 313 after discharging hot water (step S106), and the hot water discharged from the water discharge unit according to the measured value of humidity. Control may be performed to change the amount, to intermittently discharge hot water, or to change the advancing / retreating position if the water discharger is a human body washing nozzle (addition of a hot water discharge changing step).

  Further, when the humidity is checked by the humidity sensor 313, the control unit 27 may perform control to stop the operation of the electrostatic atomizing unit 31 while the detected humidity does not reach a predetermined value. As a result of continuous humidity check, if no increase in humidity is observed even after a predetermined time has elapsed, the control unit 27 determines that some abnormality has occurred in the humidification operation, and humidifies The abnormality notification units 163 and 323 may notify the abnormality (addition of an abnormality notification step). The predetermined time in this case can be defined as “humidification operation abnormality determination time”.

  Alternatively, in the control example shown in FIG. 10, when the user enters the toilet room and opens the toilet lid 14 while discharging hot water (step S <b> 105), the control unit 27 performs electrostatic charging. While stopping operation | movement of the atomization part 31, you may perform control which stops discharge of warm water (addition of a humidification operation | movement interruption step). At this time, the abnormality may be notified by the humidification abnormality notification units 163 and 323 described above. Moreover, when the user confirms the notification of abnormality and closes the toilet lid 14, the control unit 27 may control the operation of the electrostatic atomization unit 31 and the discharge of hot water to resume.

  Further, in the control example shown in FIG. 10, the control unit 27 performs the humidification operation when the measured value of humidity does not reach the predetermined value while the electrostatic atomization unit 31 is operating. The execution timing is not limited to this, and may be any time when the electrostatic atomizer 31 is operable. For example, if the remote controller 16 includes an operation switch 161 for manually operating the operation of the electrostatic atomizer 31, the electrostatic atomizer 31 can be operated even during use by the user. Therefore, the control unit 27 may perform control so that the humidification operation is performed at any time if the humidity does not reach the predetermined value without determining the operation start of the electrostatic atomization unit 31 (step S101).

  Thus, according to the present embodiment, the control unit 27 first closes the toilet lid 14 based on the detection result of the humidity sensor 313 and then discharges hot water into the toilet 50 by the water discharger. Thereby, since the inside of the toilet bowl 50 can be made into the substantially closed state from external air, the humidity in the toilet bowl 50 can be raised with the discharged hot water. The main body 12 communicates with the toilet 50, and the electrostatic atomization unit 31 generates charged fine particle water from the air in the main body 12, so that the controller 27 increases the humidity in the toilet 50. If the operation of the electrostatic atomization unit 31 is started after that, the electrostatic atomization unit 31 is capable of generating charged particulate water in the electrostatic atomization unit 31 even when the toilet room is at a low temperature or low humidity. Charged fine particle water can be generated sufficiently under the environment. Therefore, deodorization and sterilization by the electrostatic atomizer 31 can be efficiently performed regardless of the temperature or humidity of the toilet room.

  Moreover, in this Embodiment, the deodorizing part 25 is provided separately from the electrostatic atomization part 31, and the deodorizing part 25 is in use by the user (at the time of a stool and the washing | cleaning of the local part etc. by the washing nozzle part 21) The electrostatic atomizer 31 is configured to operate after use. Therefore, since the odor in the toilet bowl 50 is deodorized by the deodorizing unit 25 while the user is using it, the diffusion of the odor can be suppressed throughout the toilet room, and after use, the electrostatic atomizing unit The charged fine particle water released from 31 can remove odor components or bacteria floating in the toilet room or adhering to the wall surface, etc., and is therefore suitable for deodorization or sterilization. A deodorizing operation or a sterilizing operation can be performed.

  Furthermore, since the odor component in the toilet bowl 50 can be deodorized by the deodorizing unit 25 first, the air flow flowing from the toilet bowl 50 into the main body 12 during the operation of the electrostatic atomizing unit 31 (see the block arrow F5 in FIG. 9). ) Is a product from which odor components have been greatly removed. Therefore, it is possible to effectively suppress the possibility that the odor component enters the main body 12 and adheres to each functional unit, and the charged fine particle water can be generated by sucking the deodorized air.

  Further, in the present embodiment, the present invention has been described by taking the sanitary washing device 10 as an example, but toilet facilities to which the present invention can be applied are not limited to the sanitary washing device 10, and even a water discharge section is provided. If so, it can be applied to other toilet facilities. For example, a toilet seat device having only a heating function, an electrostatic atomizer configured to be directly attached to the toilet 50, a toilet room heating device configured to be attached to or integrated with the sanitary washing device 10 or the toilet seat device, etc. The present invention can also be suitably applied.

  Moreover, in this Embodiment, it is set as the structure which discharges warm water from the water discharge parts, such as the washing nozzle part 21, by producing | generating warm water in the heat exchange part 22 of the sanitary washing apparatus 10, However, This invention is limited to this. Alternatively, it is possible to only discharge room-temperature cleaning water that is not heated. In this case, the humidity in the toilet bowl 50 can be increased by appropriately setting various conditions such as increasing the amount of discharged cleaning water or extending the discharge time of the cleaning water.

  It should be noted that the present invention is not limited to the description of the above-described embodiment, and various modifications are possible within the scope shown in the scope of the claims, and are disclosed in different embodiments and a plurality of modifications. Embodiments obtained by appropriately combining the technical means are also included in the technical scope of the present invention.
