More specifically, the width direction is a horizontal direction parallel to the mounting wall surface of the remote control device 200.

  The light emitting element 206 is provided in the main body 202 so as to face the infrared irradiation window 205. In this example, two light emitting elements 206 corresponding to the two infrared irradiation windows 205 are provided in the main body 202. The light emitting elements 206 are arranged in the width direction of the main body 202. Each light emitting element 206 is provided at both ends in the width direction of the main body 202. Each light emitting element 206 irradiates infrared light. Each light emitting element 206 irradiates infrared light toward the outside of the main body 202 through each infrared irradiation window 205. Each light emitting element 206 is provided upward on the main body 202. Each light emitting element 206 irradiates infrared light upward of the main body 202.

  When any one of the operation units 204 is operated, the remote control device 200 transmits an optical signal corresponding to the operated operation unit 204 from each light emitting element 206 and makes it incident on the reception unit 140 of the sanitary washing device 120. . As a result, the sanitary washing device 120 performs an operation corresponding to the operation of each operation unit 204 of the remote control device 200.

FIG. 5 is a block diagram illustrating an electrical configuration of the remote control device according to the first embodiment.
As illustrated in FIG. 5, the remote control device 200 further includes a control unit 210, a power supply circuit 212, a switching unit 214, and a light detection circuit 216.

  Each operation unit 204 is connected to the control unit 210. Each operation unit 204 inputs a predetermined operation instruction to the control unit 210. The control unit 210 comprehensively controls each unit of the remote control device 200 in accordance with an operation instruction input from each operation unit 204.

  A display unit 208 is connected to the control unit 210. The control unit 210 controls display on the display unit 208. For example, the control unit 210 controls the display of the display unit 208 in accordance with an operation instruction input from each operation unit 204.

  A battery 218 is connected to the power supply circuit 212. The battery 218 is detachably attached to the main body 202 of the remote control device 200 and supplies DC power to the power supply circuit 212. The power supply circuit 212 converts the DC power supplied from the battery 218 and supplies the converted DC power to each unit such as the control unit 210. For example, the power supply circuit 212 converts the DC power of the battery 218 into DC power having a voltage value corresponding to the control unit 210 and supplies the DC power to the control unit 210. The control unit 210 starts operation in response to power supply from the power supply circuit 212. Note that the power source of the remote control device 200 is not limited to a battery, and may be a commercial power source or the like.

  The switching unit 214 and the light detection circuit 216 are provided corresponding to the light emitting element 206. Therefore, in this example, the remote control device 200 is provided with two switching units 214 and two light detection circuits 216 corresponding to the two light emitting elements 206. The configuration of each switching unit 214 is substantially the same. The configuration of each photodetection circuit 216 is substantially the same. Accordingly, only one switching unit 214 and the light detection circuit 216 will be described here.

  The switching unit 214 is connected to the light emitting element 206 and the light detection circuit 216, and is connected to the power supply voltage Vcc via the resistor 220. The power supply voltage Vcc is a DC voltage supplied from the power supply circuit 212, for example. The switching unit 214 is connected to the anode of the light emitting element 206. The switching unit 214 switches the anode connection destination of the light emitting element 206 between the power supply circuit 212 and the light detection circuit 216. The switching unit 214 is connected to the control unit 210. Switching of connection paths by the switching unit 214 is controlled by the control unit 210.

  The cathode of the light emitting element 206 is set to a common potential. The cathode of the light emitting element 206 is grounded, for example. Thus, when the anode of the light emitting element 206 is connected to the power supply circuit 212 side, the power supply voltage Vcc is supplied to the anode of the light emitting element 206, and infrared light is emitted from the light emitting element 206.

  It is known that the light emitting element 206 functions as a light emitting element that irradiates infrared light, and also functions as a photovoltaic element that generates power in accordance with the amount of light incident from the outside of the main body 202. When the connection destination of the anode of the light emitting element 206 is the light detection circuit 216 side, the power generation amount of the light emitting element 206 is input to the light detection circuit 216. When the connection destination of the anode of the light emitting element 206 is the photodetection circuit 216 side, the light emitting element 206 operates in the photovoltaic mode (solar cell mode).

  The light detection circuit 216 includes, for example, a comparator 217. The comparator 217 has a non-inverting input terminal and an inverting input terminal. A non-inverting input terminal of the comparator 217 is connected to the switching unit 214. Therefore, when the anode of the light emitting element 206 is connected to the light detection circuit 216 side, the power generation amount of the light emitting element 206 is input to the non-inverting input terminal of the comparator 217.

  The reference signal REF is input to the inverting input terminal of the comparator 217. Thereby, the comparator 217 outputs Hi (for example, +5 V) when the power generation amount of the light emitting element 206 is equal to or larger than the reference signal REF, and when the power generation amount of the light emitting element 206 is less than the reference signal REF. , Lo (for example, 0 V) is output. More specifically, the comparator 217 compares the photocurrent generated in the light emitting element 206 with the reference signal REF of the current value, and outputs the comparison result.

  When the power generation amount of the light emitting element 206 is equal to or greater than the reference signal REF, it can be considered that the illuminance around the main body 202 is equal to or greater than a predetermined value. When the power generation amount of the light emitting element 206 is less than the reference signal REF, it can be considered that the illuminance around the main body 202 is less than a predetermined value. As described above, the light detection circuit 216 detects whether or not the illuminance around the main body 202 is equal to or higher than a predetermined value in accordance with the power generation amount of the light emitting element 206.

  The light detection circuit 216 is connected to the control unit 210. The light detection circuit 216 inputs the detection result to the control unit 210. For the light detection circuit 216, for example, S-5470 series manufactured by Seiko Instruments Inc. is used. Thereby, for example, power consumption in the standby state of remote control device 200 can be suppressed.

  The controller 210 has a state change detection mode and an operation execution mode. In the state change detection mode, the control unit 210 causes the light emitting element 206 to generate power and causes the light detection circuit 216 to detect the illuminance around the main body 202. In the operation execution mode, the control unit 210 executes an operation of irradiating the light emitting element 206 with infrared light. That is, in this example, the control unit 210 executes infrared communication with the sanitary washing device 120 as a predetermined operation in the operation execution mode.

  In the state change detection mode, the control unit 210 switches from the state change detection mode to the operation execution mode when the illuminance is detected to be a predetermined value or more, and after the predetermined operation is completed, the state change from the operation execution mode is performed. Return to detection mode. In this example, after switching to the operation execution mode, after the infrared communication with the sanitary washing device 120 is completed, the state change detection mode is resumed.

  For example, in a surrounding space such as a toilet or a bathroom in a general house, the illuminance is low even during the day, and the lighting is often turned on. Therefore, when the illuminance is less than the predetermined value, it can be considered that the toilet unit 10 is in a standby state where it is not used. And when illumination changes from the state below a predetermined value to the state more than a predetermined value, it can be considered that the user started using the toilet unit 10. In other words, it can be considered that the toilet unit 10 is switched from the standby state to the use state. In other words, the state change detection mode is a mode for detecting a change of the toilet unit 10 from the standby state to the use state and a change from the use state to the standby state.

  When the illuminance is less than a predetermined value, the control unit 210 of the remote control device 200 executes, for example, power saving control in which power consumption is reduced as compared with the normal time. For example, when the illuminance is less than the predetermined value, the control unit 210 stops the power supply to the display unit 208 and turns the display unit 208 off. Thereby, it is possible to suppress power consumption during standby as compared with the case where the display unit 208 is kept on.

  The control unit 170 of the sanitary washing device 120 receives, for example, the detection result of the light detection circuit 216 from the remote control device 200, and executes power saving control with lower power consumption than normal when the illuminance is less than a predetermined value. To do. When the illuminance is less than the predetermined value, the control unit 170 turns off the display unit 144 and the toilet seat heater 172, for example. Thereby, also in the sanitary washing apparatus 120, the power consumption at the time of standby can be suppressed.

  In this example, the remote control device 200 includes two light emitting elements 206 and two light detection circuits 216. The detection of illuminance may be performed using both of the light emitting elements 206 and the light detection circuits 216, or may be performed by only one of them. The transmission of the optical signal to the sanitary washing device 120 may be performed using both of the light emitting elements 206 or only one of them.

FIG. 6 is a flowchart illustrating an example of the operation of the toilet unit according to the first embodiment.
FIG. 7 is a timing chart illustrating an example of the operation of the toilet unit according to the first embodiment.
As shown in FIGS. 6 and 7, when power is supplied from the power supply circuit 212, the control unit 210 of the remote control device 200 first starts operating in the state change detection mode (step S101 in FIG. 6). That is, the control unit 210 controls the switching unit 214 and sets the anode connection destination of the light emitting element 206 to the photodetection circuit 216 side, thereby determining whether or not the illuminance around the main body unit 202 is a predetermined value or more. The photodetection circuit 216 is made to detect.

  The controller 210 determines whether or not a change in state is detected by the light detection circuit 216. That is, it is determined whether or not the output of the comparator 217 is Hi (step S102 in FIG. 6). When the state change is not detected, the control unit 210 repeats the determination of the detection result of the light detection circuit 216. At this time, the control unit 210 performs power saving control. For example, the display unit 208 is turned off. Similarly, when the state change is not detected, the control unit 170 of the sanitary washing device 120 performs power saving control and turns off the display unit 144 and the toilet seat heater 172.

  When the change in state is detected by the light detection circuit 216, the control unit 210 determines whether or not an operation of each operation unit 204 has been detected (step S103 in FIG. 6). In addition, when a change in state is detected by the light detection circuit 216, for example, the control unit 210 temporarily switches from the change state detection mode to the operation execution mode, and transmits a light signal indicating detection of the change in state from the light emitting element 206. May be. When the control unit 170 of the sanitary washing device 120 receives an optical signal indicating detection of a change in state, for example, heating of the toilet seat heater 172 is started, the toilet seat 124 is heated to a predetermined temperature, and an operation state is displayed on the display unit 144. indicate. For example, the control unit 170 may drive the toilet lid opening / closing drive unit 173 in response to detection of the state change, and change the toilet lid 126 from the closed state to the opened state.

  When any operation of each operation unit 204 is detected, the control unit 210 switches to the power supply circuit 212 side by switching the switching unit 214 to the operation execution mode (step S104 in FIG. 6, time in FIG. 7). t11).

  When the control unit 210 of the remote control device 200 shifts to the operation execution mode, the control unit 210 transmits an optical signal corresponding to the operation instruction of the operated operation unit 204 from the light emitting element 206 (step S105 in FIG. 6, time t11 in FIG. 7). t12). When the control unit 170 of the sanitary washing device 120 receives an optical signal, the control unit 170 executes an operation corresponding to the operation instruction of the optical signal. Accordingly, the sanitary washing device 120 is remotely operated in accordance with the operation of each operation unit 204 of the remote control device 200.

  After transmitting the optical signal, the controller 210 determines whether or not a predetermined time has elapsed since the end of the transmission of the optical signal (step S106 in FIG. 6). When the predetermined time has not elapsed, the control unit 210 determines whether or not an operation of each operation unit 204 has been detected (step S107 in FIG. 6). When the operation is not detected, the control unit 210 returns to step S106, and determines whether or not a predetermined time has elapsed from the end of the transmission of the optical signal. When any operation of each operation unit 204 is detected, the control unit 210 returns to step S <b> 105 and transmits an optical signal corresponding to the operation instruction of the operated operation unit 204 from the light emitting element 206. Then, when a predetermined time has elapsed from the end of the transmission of the optical signal, the control unit 210 switches from the operation execution mode to the state change detection mode (step S108 in FIG. 6 and time t13 in FIG. 7). In other words, the process returns to step S101.

  When the light detection circuit 216 detects that the illuminance around the main body 202 is less than a predetermined value, the control unit 210 starts power saving control and turns off the display unit 208. At this time, the control unit 210 may temporarily switch from the state change detection mode to the operation execution mode, and transmit an optical signal indicating that the illuminance is less than a predetermined value from the light emitting element 206. When the control unit 170 of the sanitary washing device 120 receives an optical signal indicating that the illuminance is less than a predetermined value, for example, the heating of the toilet seat heater 172 is stopped, the display of the display unit 144 is stopped, and the toilet lid 126 is Execute a closing operation.

  As described above, the remote control device 200, which is an embodiment of a watering device, detects whether or not the illuminance around the main body 202 is greater than or equal to a predetermined value based on the amount of power generated by the light emitting element 206, and emits light. An operation of transmitting an optical signal from the element 206 is executed. In other words, the operation using the light emitting element 206 and the detection of the change in the surrounding state can be combined with the light emitting element 206. Accordingly, even when an operation using the light emitting element 206 is performed, it is not necessary to separately provide a detection sensor or the like for detecting a change in the surrounding state, and an operation using the light emitting element 206 and a change in the surrounding state are not necessary. Detection can be realized with a simple configuration.

  In remote control device 200, it is not necessary to provide a detection sensor or the like for detecting a change in state, and the number of components can be suppressed. Thereby, for example, an increase in size and manufacturing cost of the remote control device 200 can be suppressed. Further, it is not necessary to separately provide a transmission window for the detection sensor, and the design of the remote control device 200 can be improved.

  Further, by providing the light emitting element 206 upward in the main body 202, an optical signal transmitted from the light emitting element 206 can be transmitted toward the ceiling of the toilet space, and hygiene is achieved through reflection on the ceiling. An optical signal can be appropriately incident on the receiving unit 140 of the cleaning device 120.

  Further, in the state change detection mode, the control unit 210 switches to the operation execution mode in response to the input of the operation instruction and detects an optical signal corresponding to the operation instruction when the illuminance is detected to be equal to or greater than the predetermined value. Since light is transmitted from the light emitting element 206, for example, when the light emitting element 206 used for the infrared communication transmitting unit is also used for detecting the illuminance, the light is appropriately transmitted in response to an operation instruction input from each operation unit 204. Signal transmission can be performed.

  Moreover, in the toilet unit 10 of the said embodiment, the result of the illumination intensity detected with the remote control apparatus 200 is input into the sanitary washing apparatus 120, and the control part 170 of the sanitary washing apparatus 120 responds to detection of a state change, and the toilet lid 126. A predetermined operation such as opening / closing is executed. Thereby, for example, a detection sensor for detecting a state can be omitted from the sanitary washing device 120. In addition, when a human body detection sensor or the like is provided in the sanitary washing device 120, for example, there is a possibility of erroneously detecting a person who has passed the outside of the door. On the other hand, when detecting by illuminance, it is possible to suppress erroneous detection of a human passing through the outside of the door.

FIG. 8 is a block diagram illustrating a modification of the remote control device according to the first embodiment.
As illustrated in FIG. 8, the remote control device 240 of this example further includes a storage unit 242. Note that components that are substantially the same in function and configuration as those in the above embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.

  History information 244 is stored in the storage unit 242. The history information 244 stores illuminance detection results by the two light detection circuits 216. The history information 244 includes, for example, a timing at which a state above a predetermined value changes to a state below a predetermined value, a timing at which the state below a predetermined value changes to a state above a predetermined value, and the date and time when each of these timings occurred. Store it in association.

  The storage unit 242 is connected to the control unit 210. The history information 244 is generated by the control unit 210, for example. For example, each time the output state of each photodetection circuit 216 changes, the control unit 210 associates the information on the state change with the information on the date and time when the change occurred in the storage unit 242 to store the history. Information 244 is generated.

Fig.9 (a) and FIG.9 (b) are top views showing the installation example of a toilet unit.
9A and 9B, in the remote control device 240 attached to the wall surface WL of the toilet space TS (installation space), in the two light emitting elements 206 arranged in the width direction of the main body 202, A light emitting element 206 on the side close to the entrance ET of the toilet space TS and a light emitting element 206 on the side close to the toilet body 100 (the sanitary washing device 120) are generated. In the example shown in FIGS. 9A and 9B, the light emitting element 206 located on the upper side of the paper is close to the entrance ET, and the light emitting element 206 located on the lower side of the paper is close to the sanitary washing device 120.

  Based on the history information 244 stored in the storage unit 242, the control unit 210, for the two light emitting elements 206, the light emitting element 206 close to the entrance ET of the toilet space TS, the light emitting element 206 close to the sanitary washing device 120, Identify.

  For example, in the light emitting element 206 on the side close to the entrance ET of the toilet space TS, there is a high possibility that the illuminance is detected to be equal to or higher than a predetermined value compared to the far side due to opening and closing of the door. Therefore, for example, when there is a difference in the frequency (number of times) at which the illuminance is detected to be equal to or greater than a predetermined value in the illuminance detection results of the two light detection circuits 216, the control unit 210 sets the higher frequency side to the entrance ET. Identify the near side.

  Further, for example, in the light emitting element 206 on the side close to the entrance ET of the toilet space TS, it is highly likely that the illuminance becomes a predetermined value or more before the far side and becomes less than the predetermined value after the far side. Therefore, for example, when the detection timings in the detection results of the illuminances of the two light detection circuits 216 are different, the control unit 210 sets the side where the illuminance is detected to be equal to or greater than a predetermined value as the side closer to the entrance ET. Identify.

  When the control unit 210 identifies the light emitting element 206 close to the entrance ET and the light emitting element 206 close to the sanitary washing device 120 as described above, only the light emitting element 206 on the side close to the sanitary washing device 120 emits light. Send a signal. Thereby, compared with the case where an optical signal is output from both the two light emitting elements 206, the power consumption accompanying transmission of an optical signal can be suppressed. In addition, by transmitting from the side closer to the sanitary washing device 120, even when an optical signal is transmitted from only one light emitting element 206, the optical signal can be appropriately received by the receiving unit 140 of the sanitary washing device 120. .

  In addition, when the control unit 210 identifies the light emitting element 206 close to the entrance ET and the light emitting element 206 close to the sanitary washing device 120 as described above, only the light emitting element 206 on the side close to the entrance ET is used for illuminance. Detection is performed. Thereby, for example, it is possible to appropriately detect a change in state while suppressing power consumption. Further, the illuminance is detected by the light emitting element 206 close to the entrance ET, and the light signal is transmitted by the light emitting element 206 close to the sanitary washing device 120. Thereby, for example, illuminance detection and optical signal transmission can be performed simultaneously.

  Furthermore, the control unit 210 identifies the mounting direction of the main body unit 202 of the remote control device 240 from the above identification result. For example, the control unit 210 identifies whether the remote control device 240 is attached to the right wall surface WL or the left wall surface WL with respect to the toilet body 100. For example, the control unit 210 determines that the side close to the entrance ET is facing forward, and identifies the mounting direction. And the control part 210 changes operation | movement according to the identified direction. For example, the control unit 210 changes the content of the operation instruction of each operation unit 204 or the display content of the display unit 208 according to the identified orientation.

  For example, in the nozzle position adjustment button for adjusting the position of the nozzle 130, the operation unit 204 positioned forward when viewed from the user moves forward, and the operation unit 204 positioned rearward when viewed from the user moves backward. Thus, the content of the operation instruction of each operation unit 204 is changed according to the mounting direction of the main body unit 202 of the remote control device 240.

  Thereby, for example, erroneous operations can be suppressed, and usability of the remote control device 240 can be improved. Further, the setting operation and the like can be omitted by automatically identifying the direction of the main body 202 and changing the operation based on the detection result of the illuminance of each light detection circuit 216. For example, workability at the time of attachment can be improved.

  In addition, you may enable it to set manually the light emitting element 206 near the entrance ET of the toilet space TS, and the light emitting element 206 close to the sanitary washing apparatus 120 by operation of each operation part 204 etc.

(Second Embodiment)
FIG. 10 is a plan view illustrating a remote control device according to the second embodiment.
As illustrated in FIG. 10, the remote control device 250 includes a plurality of light emitting units 252a to 252f. Each of the light emitting units 252 a to 252 f is provided on the front surface 202 a of the main body unit 202. Each light emission part 252a-252f displays the operation | movement state of the remote control apparatus 250 by irradiating visible light.

  FIG. 11 is a block diagram illustrating an electrical configuration of a remote control device according to the second embodiment. As shown in FIG. 11, the remote control device 250 includes a light emitting element 254. The light emitting element 254 is used in the light emitting unit 252a, for example. The light emitting element 254 emits visible light. The light emitting element 254 is provided, for example, inside the main body 202 and irradiates visible light toward the outside of the main body 202 through an opening or a transmission window provided in the main body 202. The wavelength of visible light irradiated by the light emitting element 254 is, for example, about 380 nm to 750 nm.

  The light emitting element 254 is connected to the switching unit 214. That is, in this example, the light emitting element 206 that emits infrared light shown in the first embodiment is replaced with the light emitting element 206 that emits visible light. Thus, the photovoltaic element is not limited to the light emitting element 206 that irradiates infrared light, but may be the light emitting element 254 that emits visible light.

  When the illuminance is detected to be equal to or higher than a predetermined value in the state change detection mode, the control unit 210 performs irradiation with visible light from the light emitting element 254 as a predetermined operation. That is, the control unit 210 executes display of the operation state on the light emitting unit 252a as a predetermined operation.

  The other light emitting units 252b to 252f have light emitting elements (not shown), and display the operation state by irradiating visible light from the light emitting elements. Each light emitting element of the light emitting units 252b to 252f and the light emitting element 206 that irradiates infrared light can be controlled to be turned on and off by the control unit 210. Note that the light-emitting element 254 may be used for the other light-emitting portions 252b to 252f. Further, a plurality of switching units 214 and light detection circuits 216 may be provided so that illuminance can be detected at a plurality of locations of the light emitting units 252a to 252f.

FIG. 12 is a flowchart illustrating an example of the operation of the toilet unit according to the second embodiment.
FIG. 13 is a timing chart illustrating an example of the operation of the toilet unit according to the second embodiment.
As shown in FIGS. 12 and 13, in the operation of the control unit 210 of the remote control device 250, Steps S201 to S204 are substantially the same as Steps S101 to S104 described with respect to the first embodiment. Therefore, detailed description is omitted. In this example, when the illuminance around the main body unit 202 is less than a predetermined value, the control unit 210 executes, for example, stopping light emission of each of the light emitting units 252a to 252f as power saving control.

  The control unit 210 detects that the illuminance is equal to or higher than a predetermined value, and after transitioning to the operation execution mode in response to any operation of each operation unit 204, the light emitting unit 252a corresponding to the operated operation unit 204. ˜252f are caused to emit light, and visible light is emitted from the corresponding light emitting units 252a to 252f for a predetermined time (step S205 in FIG. 12, times t21 to t22 in FIG. 13). At this time, the control unit 210 transmits an optical signal corresponding to the operation instruction of the operated operation unit 204 from the light emitting element 206. For example, a light emitting unit that is not related to the operation of each operation unit 204, such as the light emitting unit 252f that displays the remaining amount of the battery 218, may emit light when the illuminance is determined to be equal to or greater than a predetermined value.

  The control unit 210 determines whether or not a predetermined time has elapsed since the operation of the operation unit 204 after causing the corresponding light emitting units 252a to 252f to emit light for a predetermined time (step S206 in FIG. 12). When the predetermined time has not elapsed, the control unit 210 determines whether or not an operation of each operation unit 204 has been detected (step S207 in FIG. 12). If no operation is detected, the control unit 210 returns to step S206 and determines whether or not a predetermined time has elapsed since the operation of the operation unit 204. If any operation of each operation unit 204 is detected, the control unit 210 returns to step S205 and causes the corresponding light emitting units 252a to 252f to emit light for a predetermined time. Then, when a predetermined time has elapsed since the operation of the operation unit 204, the control unit 210 switches from the operation execution mode to the state change detection mode (step S208 in FIG. 12, time t23 in FIG. 13). In other words, the process returns to step S201.

  When the light detection circuit 216 detects that the illuminance around the main body 202 is less than a predetermined value, the control unit 210 starts power saving control and stops the light emission of each of the light emitting units 252a to 252f. In addition, the control unit 210 transmits an optical signal indicating that the illuminance is less than a predetermined value from the light emitting element 206. When the control unit 170 of the sanitary washing device 120 receives an optical signal indicating that the illuminance is less than a predetermined value, for example, the heating of the toilet seat heater 172 is stopped, the display of the display unit 144 is stopped, and the toilet lid 126 is Execute a closing operation.

  As described above, also in the remote control device 250 according to the present embodiment, the light emitting element 254 that displays the operation state and the like can also be used for the detection of illuminance, and the operation using the light emitting element 254 and the change in the surrounding state Can be realized with a simple configuration.

(Third embodiment)
FIG. 14 is a block diagram illustrating an electrical configuration of a remote control device according to the third embodiment. As illustrated in FIG. 14, the remote control device 260 includes a light receiving element 262, switching units 263 and 264, and an infrared receiving circuit 266.

  The light receiving element 262 is provided in the main body 202. The light receiving element 262 receives infrared light. The light receiving element 262 is, for example, a photodiode having sensitivity to infrared light. The light receiving element 262 receives light incident from the outside of the main body 202 through, for example, an opening provided in the main body 202 or an infrared transmission window (both not shown). The light receiving element 262 is provided on the main body 202 upward. The light receiving element 262 receives infrared light incident from above the main body 202.

  The light receiving element 262 receives an infrared light signal transmitted from the sanitary washing device 120, for example. That is, remote control device 260 has a light receiving unit for infrared communication. The remote control device 26 receives the optical signal transmitted from the sanitary washing device 120 and executes an operation according to the optical signal. Thereby, for example, information on the state of the sanitary washing device 120 that cannot be known only by the remote control device 260 can be obtained. For example, information on the temperature of the toilet seat 124, information on the momentum and temperature of the washing water, information on whether the sanitary washing device 120 is operating normally or has failed, and the like can be input to the remote control device 260.

  The switching unit 263 is connected to the light receiving element 262 and the light detection circuit 216 and is connected to a common potential terminal. The switching unit 263 is connected to the anode of the light receiving element 262. The switching unit 263 switches the connection destination of the anode of the light receiving element 262 between the common potential terminal and the light detection circuit 216.

  The switching unit 264 is connected to the light receiving element 262 and the infrared receiving circuit 266 and is connected to a common potential terminal. The switching unit 264 is connected to the cathode of the light receiving element 262. The switching unit 264 switches the connection destination of the cathode of the light receiving element 262 between the common potential terminal and the infrared receiving circuit 266.

  Each switching unit 263, 264 is connected to the control unit 210. Switching of connection paths by the switching units 263 and 264 is controlled by the control unit 210.

  The light receiving element 262 functions as a light receiving element that receives infrared light, and also functions as a photovoltaic element that generates power according to the amount of visible light incident from the outside of the main body 202.

  In the state change detection mode, the controller 210 connects the anode of the light receiving element 262 to the light detection circuit 216 and connects the cathode of the light receiving element 262 to the common potential terminal. As a result, as in the above embodiments, the light receiving element 262 operates in the photovoltaic mode, and the amount of power generated by the light receiving element 262 when the visible light is received is input to the light detection circuit 216.

  The control unit 210 connects the anode of the light receiving element 262 to the common potential terminal and connects the cathode of the light receiving element 262 to the infrared receiving circuit 266 in the operation execution mode. As a result, the light receiving element 262 operates in the photoconductive mode, and the power generation amount of the light receiving element 262 due to the reception of the infrared light signal transmitted from the sanitary washing device 120 is input to the infrared receiving circuit 266. In other words, the light receiving element 262 converts the received optical signal into an electric signal and inputs it to the infrared receiving circuit 266.

  The infrared receiving circuit 266 includes, for example, an amplifier and a filter, and performs waveform shaping of the electric signal input from the light receiving element 262 and inputs it to the control unit 210. As a result, information transmitted from the sanitary washing device 120 is input to the control unit 210.

  In the state change detection mode, the control unit 210 switches from the state change detection mode to the operation execution mode when the illuminance is detected to be a predetermined value or more, and after the predetermined operation is completed, the state change from the operation execution mode is performed. Return to detection mode. For example, the control unit 210 performs reception of an optical signal by the light receiving element 262 as a predetermined operation. Then, the control unit 210 detects the state change from the operation execution mode in response to the input of the operation instruction for ending the use of the toilet unit, such as the operation of the large or small toilet flush button or the stop button. Return to mode. As described above, the photovoltaic element is not limited to the light emitting elements 206 and 254 but may be a light receiving element 262 used for infrared communication.

(Fourth embodiment)
FIG. 15 is a block diagram illustrating a partial electrical configuration of the sanitary washing device according to the fourth embodiment.
As illustrated in FIG. 15, the sanitary washing device 300 includes a light detection circuit 302, switching units 303 and 304, and an infrared reception circuit 306. The light detection circuit 302, the switching units 303 and 304, and the infrared reception circuit 306 are substantially the same as the light detection circuit 216, the switching units 263 and 264, and the infrared reception circuit 266 described with respect to the third embodiment. Therefore, detailed description is omitted. That is, in this example, as another embodiment of the watering device, the light receiving element 142 used for the infrared communication of the sanitary washing device 300 is a photovoltaic element, and the light receiving element 142 used for the infrared communication receiving unit 140 is the illuminance. This is an example that is also used for detection.

  In this example, the control unit 170 of the sanitary washing device 300 has a state change detection mode and an operation execution mode. In the state change detection mode, the control unit 170 causes the light receiving element 142 to generate power and causes the light detection circuit 302 to detect the illuminance around the main body 122. In the operation execution mode, the control unit 170 performs an operation of causing the light receiving element 142 to receive an infrared light signal. That is, in this example, control unit 170 executes infrared communication with remote control device 200 as a predetermined operation in the operation execution mode.

FIG. 16 is a flowchart illustrating an example of the operation of the toilet unit according to the fourth embodiment.
FIG. 17 is a timing chart illustrating an example of the operation of the toilet unit according to the fourth embodiment.
As shown in FIGS. 16 and 17, when power is supplied from the power supply circuit 171, the control unit 170 of the sanitary washing device 300 first starts operating in the state change detection mode (step S <b> 301 in FIG. 16). That is, the control unit 170 controls the switching units 303 and 304, connects the anode of the light receiving element 142 to the light detection circuit 302, and connects the cathode of the light receiving element 142 to the common potential terminal. The light detection circuit 302 is made to detect whether or not the illuminance around is not less than a predetermined value.

  The control unit 170 determines whether or not a state change is detected by the light detection circuit 302. That is, it is determined whether or not the output of the comparator 217 is Hi (step S302 in FIG. 16). When the state change is not detected, the control unit 170 repeats the determination of the detection result of the light detection circuit 302. At this time, the control unit 170 performs power saving control. For example, the display unit 144 and the toilet seat heater 172 are turned off.

  When a change in state is detected by the light detection circuit 302, the control unit 170 switches the switching units 303 and 304, connects the anode of the light receiving element 142 to the common potential terminal, and connects the cathode of the light receiving element 142 to the infrared receiving circuit. By connecting to 306, it shifts to the operation execution mode (step S303 in FIG. 16, time t31 in FIG. 17).

  Further, when detecting a change in state, for example, the control unit 170 starts heating the toilet seat heater 172, warms the toilet seat 124 to a predetermined temperature, and displays the operation state on the display unit 144. For example, the control unit 170 may drive the toilet lid opening / closing drive unit 173 in response to detection of the state change, and change the toilet lid 126 from the closed state to the opened state.

  When transitioning to the operation execution mode, control unit 170 determines whether an optical signal has been received from remote control device 200 within a predetermined time (step S304 in FIG. 16).

  If the optical signal is not received within the predetermined time, the control unit 170 returns from the operation execution mode to the state change detection mode (step S305 in FIG. 16). That is, the process returns to step S301.

  When the optical signal is received within a predetermined time, the control unit 170 subsequently determines whether or not the received optical signal is an operation instruction for ending use (step S306 in FIG. 16). The operation instruction to end use is, for example, an operation instruction indicating an operation of a large or small toilet flush button.

  When it is determined that the operation instruction is not an end-of-use operation, the control unit 170 controls the operation of a predetermined device of the sanitary washing device 300 in accordance with the content of the received operation instruction (Step S307 in FIG. 16 and FIG. 17). Time t32). Thereafter, control unit 170 returns to step S304 and determines whether or not an optical signal has been received from remote control device 200 within a predetermined time.

  On the other hand, if the control unit 170 determines that the operation instruction is to end use, the control unit 170 controls the operation of a predetermined device corresponding to the end of use (step S308 in FIG. 16, time t33 in FIG. 17). Thereafter, the controller 170 returns from the operation execution mode to the state change detection mode (step S309 in FIG. 16, time t34 in FIG. 17).

  When the controller 170 returns to the state change detection mode and detects that the illuminance is less than a predetermined value, for example, the heating of the toilet seat heater 172 is stopped, the display of the display unit 144 is stopped, and the toilet lid 126 is closed. Perform actions and so on.

  As described above, also in the sanitary washing device 300 which is another embodiment of the watering device, the operation using the light receiving element 142 and the detection of the change in the surrounding state can be shared by the light receiving element 142. . The operation using the light receiving element 142 and the detection of the change in the surrounding state can be realized with a simple configuration. Also in the sanitary washing device 300, the number of parts can be suppressed, and the enlargement and the manufacturing cost can be suppressed. There is no need to separately provide a transmission window or the like for the detection sensor, and the design can be improved.

(Fifth embodiment)
FIG. 18 is a block diagram illustrating a partial electrical configuration of a sanitary washing device according to the fifth embodiment.
As illustrated in FIG. 18, the sanitary washing device 310 includes a switching unit 312 and a resistor 314. The switching unit 312 is connected to the light emitting element 146a and the light detection circuit 302 provided in the display unit 144 of the sanitary washing device 310, and is connected to the power supply voltage Vcc via the resistor 314.

  Since the switching unit 312 is the same as the photodetection circuit 216 described with respect to the first embodiment, detailed description thereof is omitted. That is, in this example, the light emitting element 146d used for the display unit 144 that displays the operation state of the sanitary washing device 310 is a photovoltaic element, and the light emitting element 146d used for displaying the operation state by visible light is used to detect illuminance. This is an example of the combined use.

  The other light emitting elements 146a to 146c of the display unit 144 are configured to be controlled to be turned on and off by the control unit 170. Note that the detection of illuminance may also be performed by the other light emitting elements 146a to 146c of the display unit 144. Further, a plurality of switching units 312 and light detection circuits 302 may be provided so that illuminance can be detected at a plurality of locations of the light emitting elements 146a to 146d of the display unit 144.

  In the state change detection mode, the control unit 170 of the sanitary washing device 310 causes the light emitting element 146d to generate power and causes the light detection circuit 302 to detect the illuminance around the main body 122. And control part 170 performs operation which irradiates visible light to light emitting element 146d in operation execution mode. In this example, the control unit 170 executes display of the operation state of the sanitary washing device 310 as a predetermined operation.

FIG. 19 is a flowchart illustrating an example of the operation of the toilet unit according to the fifth embodiment.
FIG. 20 is a timing chart illustrating an example of the operation of the toilet unit according to the fifth embodiment.
As shown in FIGS. 19 and 20, when power is supplied from the power supply circuit 171, the control unit 170 of the sanitary washing device 310 first starts operating in the state change detection mode (step S <b> 401 in FIG. 19). That is, the control unit 170 controls the switching unit 312 to connect the anode of the light emitting element 146d to the light detection circuit 302, thereby determining whether or not the illuminance around the main body 122 is equal to or higher than a predetermined value. 302 makes it detect.

  The control unit 170 determines whether or not a state change is detected by the light detection circuit 302. That is, it is determined whether or not the output of the comparator 217 is Hi (step S402 in FIG. 19). When the state change is not detected, the control unit 170 repeats the determination of the detection result of the light detection circuit 302. At this time, the control unit 170 performs power saving control. For example, the display unit 144 and the toilet seat heater 172 are turned off.

  When the control unit 170 detects a change in state, for example, heating of the toilet seat heater 172 is started, the toilet seat 124 is heated to a predetermined temperature, and an operation state is displayed on the display unit 144. For example, the control unit 170 displays the normal operation state by causing the light emitting element 146a of the display unit 144 to emit light. For example, when the toilet seat 124 is heated, the fact that the toilet seat 124 is being heated is displayed by causing the light emitting element 146b to emit light. When the power saving operation is being performed, the light emitting element 146c is caused to emit light to indicate that the power saving operation is being performed. For example, the control unit 170 may drive the toilet lid opening / closing drive unit 173 in response to detection of the state change, and change the toilet lid 126 from the closed state to the opened state.

  Further, when detecting a change in state, the control unit 170 subsequently determines whether or not a visible light emission command is detected (step S403 in FIG. 19). When the visible light emission command is not detected, the control unit 170 returns to step S402 and repeats the determination of whether or not the state change is detected and the determination of whether or not the visible light emission command is detected.

  On the other hand, when the control unit 170 detects a visible light emission command, the control unit 170 switches to the switching unit 312 and shifts to the operation execution mode by connecting the anode of the light emitting element 146d to the power supply circuit 171 side (step S404 in FIG. 19). , Time t41 in FIG.

  When the control unit 170 shifts to the operation execution mode, the light emitting element 146d of the display unit 144 emits light for a predetermined time to emit visible light from the light emitting element 146d (step S405 in FIG. 19 and times t41 to t42 in FIG. 20). ).

  The control unit 170 may, for example, input an operation instruction from the remote control device 200 to clean the nozzle 130 using the functional water generated in the electrolytic cell unit 156, or may discharge the functional water from the spray nozzle 163 to the toilet 110. When an instruction to spray the bowl portion 112 to clean the bowl portion 112 is detected, these processes are executed and the light emitting element 146d is caused to emit light, thereby displaying the execution of the cleaning to the user or the like. .

  The controller 170 causes the light emitting element 146d to emit light for a predetermined time, and then returns from the operation execution mode to the state change detection mode (step S406 in FIG. 19 and time t42 in FIG. 20). That is, the process returns to step S401.

  As described above, also in the sanitary washing device 310, the operation using the light emitting element 146d and the detection of the change in the surrounding state can be shared by the light emitting element 146d. An operation using the light-emitting element 146d and detection of a change in the surrounding state can be realized with a simple configuration. Also in the sanitary washing device 310, the number of parts can be suppressed, and the enlargement and the manufacturing cost can be suppressed. There is no need to separately provide a transmission window or the like for the detection sensor, and the design can be improved.

  For example, when the sanitary washing apparatus has a function of transmitting to the remote control device, a light emitting element that transmits an infrared light signal may be used as the photovoltaic element. In this case, for example, the same configuration as that of the switching unit 214 and the photodetection circuit 216 described in the first embodiment can be employed.

  As described above, the photovoltaic element may be a light emitting element that emits infrared light, a light emitting element that emits visible light, or a light receiving element that receives infrared light. For example, a light emitting diode is used as the light emitting element. For example, a photodiode is used as the light receiving element. The photovoltaic device is not limited to these, and may be any device that can generate power according to the amount of light incident from the outside of the main body and can also function as a light emitting device or a light receiving device.

  In each said embodiment, the sanitary washing apparatus is shown as a toilet apparatus. The tray device is not limited to the sanitary washing device, and may be a heating toilet seat having only a toilet seat heating function, for example.

  Moreover, in each said embodiment, the remote control apparatus, toilet apparatus, etc. which are used in a toilet space are shown as watering equipment. The watering device is not limited to these, and may be, for example, a remote control device used in a bathroom.
