  For example, when the remote controller 2 performs an operation to instruct execution of the local cleaning by the user, the local cleaning device 9 cleans the local cleaning nozzle 10 in the standby position from the nozzle opening 11 inside the toilet body 3. The local cleaning for cleaning the local part of the human body is performed by advancing to the position and discharging the cleaning water from the tip of the local cleaning nozzle 10. Then, the local cleaning device 9 stops the local cleaning when the user performs an operation to stop the local cleaning in the remote control device 2, for example, and retracts the local cleaning nozzle 10 at the cleaning position to the standby position. Let

  The shutter unit 12 closes the nozzle opening 11 in a state where the local cleaning nozzle 10 is retracted to the standby position in the main body cover 5, so that dirt, washing water splashes, etc. are applied to the local cleaning nozzle 10, This prevents entry into the cover 5. Further, the shutter unit 12 rotates with the advance of the local cleaning nozzle 10 to open the nozzle opening 11.

  Further, the local cleaning device 9 forms a water film with hot water on the surface of the local cleaning nozzle 10 in a state where the local cleaning nozzle 10 has advanced from the nozzle opening 11. Here, the hot water may be cold water or hot water. Below, the structure of the local washing | cleaning apparatus 9 which concerns on this embodiment is demonstrated concretely using FIG.

  As shown in FIG. 2, the local cleaning device 9 includes a first flow path 13, a second flow path 14, a water supply valve 15, a hot water generation section 16, and a cleaning section 17.

The first flow path 13 is a flow path for allowing water from the water supply source S to flow into the hot water generating unit 16 via the water supply valve 15.
The second flow path 14 is a flow path for supplying hot water from the hot water generating unit 16 to the cleaning unit 17.

  The water supply valve 15 is provided in the first flow path 13 and controls the water supply from the water supply source S to the hot water generation unit 16 by opening or closing the first flow path 13. Specifically, the water supply valve 15 opens the first flow path 13 when controlled to the open state by the control of the cleaning unit 17. As a result, water from the water supply source S flows into the hot water generator 16 via the first flow path 13. On the other hand, when the water supply valve 15 is controlled to be closed by the control of the cleaning unit 17, the water supply valve 15 closes the first flow path 13. Thereby, the inflow of the water to the warm water production | generation part 16 is stopped.

  The warm water generator 16 heats the water flowing in through the first flow path 13 to a predetermined temperature to generate warm water. Then, the hot water generation unit 16 supplies hot water heated to a predetermined temperature to the cleaning unit 17 via the second flow path 14. Below, the structure of the warm water production | generation part 16 is demonstrated concretely.

  The hot water generator 16 includes a heater 161, a temperature sensor 162, and a temperature controller 163.

  The heater 161 heats the water flowing in through the first flow path 13 to a predetermined temperature based on the control of the temperature control unit 163. Then, the hot water generated by heating by the heater 161 is supplied to the cleaning unit 17 through the second flow path 14.

  The temperature sensor 162 is a sensor that is provided in the second flow path 14 and measures the temperature of hot water heated by the heater 161, and is, for example, a thermistor. The temperature sensor 162 outputs the measured temperature to the temperature control unit 163.

  The temperature control unit 163 controls the output of the heater 161 so that the temperature measured by the temperature sensor 162 becomes the predetermined temperature. The temperature control unit 163 can control the temperature of the hot water supplied to the second flow path 14 to an arbitrary temperature.

  The cleaning unit 17 includes a local cleaning nozzle 10, a water film port 171, branch channels 172 to 174, a flow control valve 175, a flow control valve 176, a drive unit 177, and a control device 178.

  The local cleaning nozzle 10 is at least one of a pair of local cleaning nozzles including a buttocks cleaning nozzle 111 and a bidet nozzle 112. In the following description, when each of the buttocks cleaning nozzle 111 and the bidet nozzle 112 is not distinguished, it is simply denoted as “local cleaning nozzle 10”.

  The water film port 171 is an opening for forming a water film of cold water or hot water on the surface of the local cleaning nozzle 10. In the present embodiment, the cleaning unit 17 discharges hot water from the water film port 171 toward the surface of the local cleaning nozzle 10, so that water of hot water is applied to the surface of the local cleaning nozzle 10 that has advanced from the nozzle opening 11. A film (hereinafter referred to as “warm water film”) is formed.

  The branch channels 172 to 174 are channels that branch from the second channel 14.

The branch flow path 172 branches from the second flow path 14 and communicates with the tip of the buttocks cleaning nozzle 111.
The branch channel 173 branches from the second channel 14 and communicates with the tip of the bidet nozzle 112.
The branch channel 174 branches from the second channel 14 and communicates with the water film port 171.

  The flow control valve 175 selects one or more branch flow channels through which the hot water generated by the hot water generating unit 16 flows from the branch flow channel 172 and the branch flow channel 173, and selects the selected branch flow channel (hereinafter, “selected branch”). The hot water generated by the hot water generator 16 is supplied to the “flow channel”. However, the flow control valve 175 may not select the selected branch flow path when the hot water generated by the hot water generation unit 16 is not flowed into any branch flow path of the branch flow path 172 and the branch flow path 173. it can. Furthermore, the flow control valve 175 can adjust the flow rate of the hot water flowing through the selected branch flow path. Specifically, the flow control valve 175 can adjust the flow rate of the cleaning water discharged from the tip of the local cleaning nozzle 10 by adjusting the opening degree from the control device 178.

  The flow control valve 176 is provided in the branch flow path 174, and the flow rate of the hot water flowing through the branch flow path 174 can be adjusted by adjusting the opening degree from the control device 178. That is, the flow control valve 176 can adjust the flow rate of hot water discharged from the water film port 171 to the surface of the local cleaning nozzle 10.

  The flow control valve 176 and the control device 178 function as a flow rate adjusting unit that adjusts the flow rate of hot water discharged from the water film port 171 in order to form a hot water film on the surface of the local cleaning nozzle 10.

  Based on the control by the control device 178, the drive unit 177 can advance and retract the pair of butt cleaning nozzles 111 and the bidet nozzle 112 individually between the standby position and the cleaning position.

The control device 178 controls opening or closing of the first flow path 13 by controlling driving of the water supply valve 15.
The control device 178 controls the local cleaning by the local cleaning nozzle 10 by opening or closing the flow control valve 175. Further, the control device 178 adjusts the flow rate of the hot water discharged from the local cleaning nozzle 10 by adjusting the opening degree of the flow control valve 175.

  The control device 178 controls the formation of the hot water film on the surface of the local cleaning nozzle 10 by opening or closing the flow control valve 176. Furthermore, the control device 178 can adjust the flow rate of the hot water discharged on the surface of the local cleaning nozzle 10 in order to form the hot water film by adjusting the opening degree of the flow control valve 176.

  Here, in a state where the local cleaning nozzle 10 has advanced from the nozzle opening 11, the control device 178 discharges hot water from the water film port 171 to the surface of the local cleaning nozzle 10 to form a hot water film. And in forming the said hot water film, the control apparatus 178 adjusts the flow volume of the warm water discharged from the water film port 171 to the surface of the local washing nozzle 10 arbitrarily by adjusting the opening degree of the flow control valve 176. It is possible. That is, the control device 178 forms hot water film by discharging hot water onto the surface of the local cleaning nozzle 10 during local cleaning or while the local cleaning nozzle 10 is moving between the standby position and the cleaning position. At the same time, the flow rate of the hot water can be arbitrarily adjusted.

  Note that “the state in which the local cleaning nozzle 10 has advanced from the nozzle opening 11” means that the local cleaning nozzle 10 has moved from the standby position to the cleaning position, a state in which local cleaning is being performed, and cleaning. It includes at least one of the states of moving from the position to the standby position.

  Below, operation | movement of the hot water film formation of the local washing | cleaning apparatus 9 which concerns on one Embodiment of this invention is demonstrated using FIG. In the following description, as the advance / retreat operation of the local cleaning nozzle 10, the advance / retreat operation of the buttocks cleaning nozzle 111 will be described as an example.

  For example, when the user operates the local cleaning button in the remote control device 2, the control device 178 detects the operation. When the control device 178 detects that the local washing button has been operated, the control device 178 controls the water supply valve 15 to open the first flow path 13 and also controls the driving of the driving unit 177 to set the standby position. The advance operation of the buttocks cleaning nozzle 111 in the HP is started (time t1).

  In addition, when the buttocks cleaning nozzle 111 advances from the nozzle opening 11 at time t1, the control device 178 opens the flow control valve 176. Furthermore, the control device 178 controls the opening degree of the flow control valve 176 to the first opening degree. As a result, the hot water generated by the hot water generator 16 passes through the branch channel 174 and is discharged from the water film port 171 at the first flow rate F1. Therefore, a warm water film is formed on the surface of the cleaning nozzle 111 by the warm water at the first flow rate F1.

  When the buttocks cleaning nozzle 111 advances to the cleaning position TP (time t2), the control device 178 controls the driving unit 177 to stop the advancement operation of the buttocks cleaning nozzle 111. Then, the control device 178 controls the flow control valve 175 to select the branch flow path 172 as the selected branch flow path and open the flow control valve 175 in order to perform local cleaning. Thereby, warm water is discharged as washing water from the front-end | tip part of the nozzle 111 for butt washing | cleaning toward a user's local part, and local cleaning is performed.

  Here, when the local cleaning is executed at time t2, the control device 178 reduces the opening of the flow control valve 176 from the first opening to the second opening (<first opening). The flow rate of the hot water discharged from the water film port 171 is decreased from the first flow rate F1 to the second flow rate F2. Then, during the local cleaning (time t2 to t3), the control device 178 controls the opening of the flow control valve 176 to the second opening, and discharges hot water at the second flow rate F2 from the water film port 171. Let This is because there is a possibility that dirt is less likely to adhere to the buttocks cleaning nozzle 111 during local cleaning than during the advancement operation (time t1 to t2) of the buttocks cleaning nozzle 111. Therefore, the control device 178 reduces the flow rate of the hot water discharged from the water film port 171 during the local cleaning, rather than the advance operation of the buttocks cleaning nozzle 111. Thereby, the splash of the splash which generate | occur | produces when the warm water discharged from the water film opening | mouth 171 lands on the toilet bowl and sealing water of a toilet bowl main body can be reduced.

  When an operation for instructing the user to stop the local cleaning is performed by the remote control device 2 during the local cleaning, the control device 178 detects the operation and closes the flow control valve 175 to perform the second operation. The supply of hot water from the flow path 14 to the branch flow path 172 is stopped. As a result, the local cleaning is stopped. Then, the control device 178 controls the driving of the drive unit 177 to start the retreat operation of the butt cleaning nozzle 111 at the cleaning position (time t3).

  Here, when the retracting operation of the buttocks cleaning nozzle 111 starts at time t3, the control device 178 changes the opening degree of the flow control valve 176 from the second opening degree to the third opening degree (<second opening degree). The flow rate of the hot water discharged from the water film port 171 is decreased from the second flow rate F2 to the third flow rate F3. This is because it is assumed that during the retraction operation of the buttocks cleaning nozzle 111 (time t3 to t4), the local cleaning has already been completed, and therefore the possibility that dirt is attached to the cleaning nozzle 111 is extremely low. It is. Therefore, the control device 178 reduces the flow rate of the hot water discharged from the water film port 171 during the retracting operation of the buttocks cleaning nozzle 111 than during the local cleaning. Thereby, the splash of the splash which generate | occur | produces when the warm water discharged from the water film opening | mouth 171 lands on the toilet bowl and sealing water of a toilet bowl main body can be reduced.

When the buttocks cleaning nozzle 111 is retracted to the standby position HP, the control device 178 closes the flow adjustment valve 176 to stop the discharge of hot water from the water film port 171. Thereby, the formation of the water film on the surface of the buttocks cleaning nozzle 111 is stopped.
In the above embodiment, the controller 178 lowers the opening of the flow control valve 176 to the third opening during the retraction operation of the buttocks cleaning nozzle 111 (time t3 to t4), and from the water film port 171. Although the flow rate of the discharged hot water is lowered to the third flow rate F3, the present invention is not limited to this. For example, the control device 178 may close the flow control valve 176 and stop the discharge of hot water from the water film port 171 during the retracting operation (time t3 to t4) of the buttocks cleaning nozzle 111.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

(Modification 1)
In the above embodiment, the cleaning unit 17 discharges the hot water from the water film port 171 during the entire period when the local cleaning nozzle 10 is advanced, but the present invention is not limited to this. For example, the cleaning unit 17 may discharge hot water from the water film port 171 only within a predetermined period during the advance operation of the local cleaning nozzle 10.
Hereinafter, an operation of discharging hot water from the water film port 171 only within a predetermined period during the advance operation of the local cleaning nozzle 10 will be described with reference to FIG.

  For example, when the user operates the local cleaning button in the remote control device 2, the control device 178 detects the operation. When the control device 178 detects that the local washing button has been operated, the control device 178 controls the water supply valve 15 to open the first flow path 13 and also controls the driving of the driving unit 177 to set the standby position. The advance operation of the buttocks cleaning nozzle 111 in the HP is started (time t1).

  The control device 178 opens the flow adjustment valve 176 and opens the flow adjustment valve 176 when the buttocks cleaning nozzle 111 in the standby position HP advances from the nozzle opening and reaches the predetermined position MP during the advance operation. The opening degree of the valve 176 is controlled to the first opening degree (time t1 ′). Here, for example, the predetermined position MP is a position between the standby position HP and the cleaning position TP, and is an area in which filth does not easily adhere to the advanced local cleaning nozzle 10 (the distance between the standby position HP and the predetermined position MP). Between the predetermined position MP and the cleaning position TP).

  As described above, since the control device 178 does not easily attach dirt to the butt washing nozzle 111 from the start of the advance operation until the butt washing nozzle 111 reaches the predetermined position MP, the butt washing nozzle 111 is used. Does not form a hot water film on the surface of Thereby, the splash of the splash which generate | occur | produces when the warm water discharged from the water film opening | mouth 171 lands on the toilet bowl and sealing water of a toilet bowl main body can be reduced. Then, the control device 178 forms a hot water film on the surface of the buttocks cleaning nozzle 111 because the filth easily adheres to the buttocks cleaning nozzle 111 when the buttocks cleaning nozzle 111 reaches the predetermined position MP.

  When the buttocks cleaning nozzle 111 advances to the cleaning position TP (time t2), the control device 178 controls the driving unit 177 to stop the advancement operation of the buttocks cleaning nozzle 111. Then, the control device 178 controls the flow control valve 175 to select the branch flow path 172 as the selected branch flow path and open the flow control valve 175 in order to perform local cleaning. Thereby, warm water is discharged as washing water from the front-end | tip part of the nozzle 111 for butt washing | cleaning toward a user's local part, and local cleaning is performed.

  In addition, when the local cleaning is executed at time t2, the control device 178 lowers the opening of the flow control valve 176 to the second opening, and sets the flow rate of the hot water discharged from the water film port 171 to the second. The flow rate is reduced to F2. Then, during the local cleaning (time t2 to t3), the control device 178 controls the opening of the flow control valve 176 to the second opening, and discharges hot water at the second flow rate F2 from the water film port 171. Let

  When an operation for instructing the user to stop the local cleaning is performed by the remote control device 2 during the local cleaning, the control device 178 detects the operation and closes the flow control valve 175 to perform the second operation. The supply of hot water from the flow path 14 to the branch flow path 172 is stopped. As a result, the local cleaning is stopped. Then, the control device 178 controls the drive of the drive unit 177 to start the retracting operation of the weed cleaning nozzle 111 at the cleaning position TP (time t3).

  In addition, when the retracting operation of the buttocks cleaning nozzle 111 is started at time t3, the control device 178 lowers the opening degree of the flow control valve 176 to the third opening degree, and warm water discharged from the water film port 171. The flow rate is lowered to the third flow rate F3.

  When the buttocks cleaning nozzle 111 is retracted from the cleaning position TP to the predetermined position MP (time t3 ′), the control device 178 closes the flow control valve 176, thereby discharging hot water from the water film port 171. Stop. Thereby, the splash of the splash which generate | occur | produces when the warm water discharged from the water film opening | mouth 171 lands on the toilet bowl and sealing water of a toilet bowl main body can be reduced.

  The control device 178 stops the retracting operation when the buttocks cleaning nozzle 111 is retracted to the standby position HP (time t4). In the first modification, the control device 178 lowers the opening of the flow control valve 176 to the third opening during the retracting operation of the buttocks cleaning nozzle 111 (time t3 to t3 ′), Although the flow rate of the hot water discharged from 171 is lowered to the third flow rate F3, the present invention is not limited to this. For example, the control device 178 may close the flow control valve 176 and stop the discharge of hot water from the water film port 171 during the retracting operation (time t3 to t4) of the buttocks cleaning nozzle 111.

(Modification 2)
In the above embodiment, the cleaning unit 17 discharges a constant amount of hot water from the water film port 171 during the entire period of the advance operation of the local cleaning nozzle 10, but the present invention is not limited to this. For example, the cleaning unit 17 may adjust the flow rate of the hot water discharged from the water film port 171 according to the movement position of the local cleaning nozzle 10 when the local cleaning nozzle 10 is advanced or retracted.
Below, the operation | movement which adjusts the flow volume of the warm water discharged from the water film port 171 according to the movement position of the local washing nozzle 10 is demonstrated using FIG.

  For example, when the user operates the local cleaning button in the remote control device 2, the control device 178 detects the operation. When the control device 178 detects that the local washing button has been operated, the control device 178 controls the water supply valve 15 to open the first flow path 13 and also controls the driving of the driving unit 177 to set the standby position. The advance operation of the buttocks cleaning nozzle 111 in the HP is started (time t1).

  The control device 178 opens the flow control valve 176 when the buttocks cleaning nozzle 111 starts the advance operation at time t1. Then, the control device 178 changes the opening degree of the flow control valve 176 in accordance with the position (movement position) at which the buttocks cleaning nozzle 111 moves when the buttocks cleaning nozzle 111 moves forward.

  Specifically, the control device 178 increases the opening degree of the flow control valve 176 as the buttocks cleaning nozzle 111 approaches the cleaning position TP when the buttocks cleaning nozzle 111 moves forward. Accordingly, the control device 178 can increase the flow rate of the hot water discharged from the water film port 171 as the buttocks cleaning nozzle 111 approaches the cleaning position TP.

  When the buttocks cleaning nozzle 111 advances to the cleaning position TP (time t2), the control device 178 controls the driving unit 177 to stop the advancement operation of the buttocks cleaning nozzle 111. Then, the control device 178 controls the flow control valve 175 to select the branch flow path 172 as the selected branch flow path and open the flow control valve 175 in order to perform local cleaning. Thereby, warm water is discharged as washing water from the front-end | tip part of the nozzle 111 for butt washing | cleaning toward a user's local part, and local cleaning is performed.

  In addition, when the local cleaning is executed at time t2, the control device 178 maintains the opening of the flow control valve 176 at a constant value (for example, the first opening or the second opening). The flow rate of the hot water discharged from the water film port 171 is kept constant.

  When an operation for instructing the user to stop the local cleaning is performed by the remote control device 2 during the local cleaning, the control device 178 detects the operation and closes the flow control valve 175 to perform the second operation. The supply of hot water from the flow path 14 to the branch flow path 172 is stopped. As a result, the local cleaning is stopped. Then, the control device 178 controls the driving of the drive unit 177 to start the retreat operation of the butt cleaning nozzle 111 at the cleaning position (time t3).

  Further, when the retracting operation of the buttocks cleaning nozzle 111 is started at time t3, the control device 178 changes the opening degree of the flow control valve 176 according to the movement position of the buttocks cleaning nozzle 111. Specifically, the control device 178 decreases the opening degree of the flow control valve 176 as the buttocks cleaning nozzle 111 approaches the standby position HP during the retracting operation of the buttocks cleaning nozzle 111. Thereby, the control apparatus 178 can reduce the flow volume of the hot water discharged from the water film port 171 as the buttocks cleaning nozzle 111 approaches the standby position HP.

  Therefore, it is possible to reduce splashing of splashes generated by the hot water discharged from the water film port 171 landing on the toilet bowl or the sealing water of the toilet body.
