Description

  The present invention relates to a toilet seat device such as a heated toilet seat and a warm water flush toilet seat and a toilet device including the toilet seat device, and more particularly, to reduce power consumption of a relay drive unit of an earth leakage breaker that operates when the device leaks. It is.

  Conventionally, toilet seat devices such as this type of heated toilet seat and warm water flush toilet seat are sanitary products that are installed and used in an environment where water is used. It has a function (for example, refer patent document 1). FIG. 13 shows a conventional warm water cleaning toilet seat device described in Patent Document 1.

  In FIG. 13, the warm water washing toilet seat device has a power plug 30 that can be attached to and detached from a power outlet (not shown) on the wall of the toilet room in order to obtain electric power, and the hot water washing toilet seat device body 31 includes a leakage prevention circuit 32. The structure etc. which are known are known. In general, an earth leakage breaker or an earth leakage breaker circuit (hereinafter collectively referred to as an earth leakage breaker for convenience) uses mechanical means typified by a relay 33 to reliably break an electrical connection during operation. It is done.

  By the way, in order to ensure the operation at the time of electric leakage, the electric leakage breaker 32 needs to periodically perform an operation test to confirm whether normal operation can be performed. A typical abnormality in the relay 33 is welding of a relay contact. Therefore, an operation check test button 34 is usually provided on the warm water washing toilet seat main body 31 including the earth leakage breaker 32.

When the user of the warm water flush toilet seat presses the operation check test button 34, a simulated leakage state is generated in the leakage breaker 32. Therefore, the relay contact of the relay 33 of the leakage breaker 32 33a is blocked. Normally, since the voltage is applied to the coil portion 33b of the relay 33 in the normal state, power consumption is always generated in the coil portion 33b. In addition, there is a configuration in which such a hot water washing toilet seat device has an earth leakage breaker integrated with a power plug.
JP 2008-082044 A

  However, in the conventional warm water washing toilet seat device, a normal voltage is applied to the coil portion 33b of the relay 32 regardless of whether the person is in the vicinity or the person operates the device. There was a problem that power consumption occurred constantly. In other words, in this type of toilet seat device, the rated voltage continues to be applied to the relay drive part of the earth leakage breaker at all times, and the time that the toilet seat device is actually used is small. Used a lot of big power.

  In view of the problems of the conventional warm water washing toilet seat device, the problem to be solved by the present invention is to reduce the power consumption of the earth leakage circuit breaker such as the hot water washing toilet seat device and to save power of the device. To provide an apparatus.

In order to solve the above problems, a toilet seat device according to the present invention always closes a toilet seat, a heater such as a toilet seat heater that heats the toilet seat, and a main power supply path that supplies power to the heater. When a circuit is leaked, it opens and shuts off, and after a voltage is applied and the main feeding path is closed, even if the voltage is lowered, the relay can maintain the closed state and whether or not there is a leakage through the main feeding path And a ground fault circuit breaker having a relay drive unit that drives the relay so as to shut off and close the main power supply path, and a control unit that controls the relay drive unit. When the toilet seat is kept warm, the voltage applied to the relay drive unit is reduced.

  As a result, the power consumption of the relay drive unit can be reduced, and the power consumption of the apparatus can be reduced.

  As described above, according to the present invention, when the device is not used by the control means, the voltage of the relay drive unit of the earth leakage circuit breaker is reduced, so even if it is always energized, the relay drive unit is more than conventional. Therefore, it is possible to significantly reduce the power consumption of the apparatus.

  1st invention always opens a toilet seat, a heater such as a toilet seat heater for heating the toilet seat, and a main power supply path for supplying power to the heater, and opens when the main power supply path is leaked. The main power supply path is switched according to whether there is a leakage through the main power supply path and a relay that can maintain the closed state even if the voltage is lowered after the main power supply path is closed by applying a voltage. An earth leakage circuit breaker having a relay drive unit that drives the relay to open and close so as to shut off and close, and a control unit that controls the relay drive unit, and the control unit is configured to keep the toilet seat warm. The voltage applied to the relay drive unit is lowered, and thus the power consumption of the relay can be reduced.

  That is, in this type of toilet seat device, the rated voltage is continuously applied to the relay drive unit of the earth leakage circuit breaker and the toilet seat device is actually used for a short time. Although the power was used, when the toilet seat was kept warm, the rated voltage applied to the relay drive could be lowered, reducing the power consumption of the relay drive even if it was always energized, greatly In addition, it is possible to reduce the power consumption of the equipment.

  Further, it is possible to realize the maximum power saving by controlling the energization rate of the coil freely by knowing whether or not a person is in the vicinity of the apparatus or the usage state of the toilet seat apparatus.

  In the second invention, in particular, in the first invention, the control means reduces the voltage applied to the relay drive unit when a person is not using the cleaning device. The power consumption of the relay drive unit can be reduced, and the power consumption of the device can be reduced.

  In the third invention, in particular, in the first invention or the second invention, the control means reduces the voltage applied to the relay drive unit when a person is not seated on the toilet seat, and is continuously energized. However, the power consumption of the relay drive unit can be reduced, and the power saving of the device can be achieved.

  According to a fourth aspect of the invention, in particular, the control means of any one of the first to third aspects of the present invention provides a voltage applied to the relay drive unit when the device is not operated by an operation unit such as a cleaning device by a person. The power consumption of the relay drive unit can be reduced and the power consumption of the apparatus can be reduced even if the power is constantly energized.

In the fifth invention, in particular, the control means of any one of the first to fourth inventions reduces the voltage applied to the relay drive unit when the toilet lid of the toilet seat is in a closed state, and is always energized. Even if the operation is continued, the power consumption of the relay drive unit can be reduced, and the power consumption of the apparatus can be reduced.

  A sixth aspect of the invention is a toilet apparatus in which a toilet seat device according to any one of the first to fifth aspects of the invention is provided in a toilet, whereby the action described in any one of the first to fifth aspects of the invention is provided. It can be a toilet device having an effect.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
1 is a perspective view of a toilet apparatus equipped with the toilet seat apparatus according to Embodiment 1 of the present invention, FIG. 2 is a control block diagram of the toilet seat apparatus, and FIG. 3 is a voltage switching circuit in a leakage breaker of the toilet seat apparatus. FIG. 4 is a time chart of the voltage switching circuit.

  As shown in FIG. 1, the toilet apparatus includes a toilet seat body 4 provided sideways on the toilet 1 and the rear end portion thereof, and provided with a toilet seat 2 and a toilet lid 3 that can be turned upside down. The toilet seat device body 4 incorporates a control block shown in FIG.

  That is, the toilet seat heater 5 that heats the toilet seat 2, the warm water heater 7 that heats the wash water that is washed by jetting warm water from the washing nozzle 6 toward the human body portion after the toilet is used, and the human body portion that is wet by the washing is heated. In order to obtain electric power, the drying heaters 8 that are dried with wind are connected to the main power supply path 9 respectively, and the main power supply path 9 is cut off when there is a leakage through the main power supply path 9, and the main power supply path 9 is normal when there is no leakage. Is connected to an AC power source (a power outlet on the wall of the toilet room) via the earth leakage circuit breaker 10 which is always closed.

  The earth leakage breaker 10 always closes the main power supply path 9 that supplies power to the heater such as the toilet seat heater 5, the hot water heater 7, and the drying heater 8, and is opened when a leakage occurs through the main power supply path 9. Further, for example, the relay 11 and the main power supply which can maintain the closed state of the main power supply path 9 even if the rated voltage V0 is slightly lowered to V1 after the rated voltage V0 is applied and the main power supply path 9 is closed. The relay drive unit 12 that drives the relay 11 to open and close so as to shut off and close the main power supply path 9 according to the presence or absence of leakage through the path 9 and the leakage detection means 13 that detects the presence or absence of leakage through the main power supply path 9 It is composed.

  The control means 14 is composed of a microcomputer and its peripheral circuits, has a built-in program for executing the operations and actions described below, and the presence or absence of leakage through the main power supply path 9 detected by the leakage detection means 13 Accordingly, the relay drive unit 12 is controlled to open and close the relay 11.

  In particular, in the present embodiment, the control means 14 uses the holding function of the coil 11b to suppress the power consumption of the relay drive unit 12 including the coil 11b that opens and closes the contact 11a of the relay 11, and the relay 11 is the main power supply. After the passage 9 is closed and when the toilet seat 2 is kept warm (when the user does not use the toilet seat main body 4), the voltage applied to the relay drive unit 12, for example, the rated voltage V0 is set to V1. The power consumption of the toilet seat main body 4 is reduced slightly, and is characterized in that.

  The holding function of the coil 11b described above means that once the coil 11b of the relay 11 is energized by applying the rated voltage V0, the applied voltage is reduced to a certain level, and then the contact of the relay 11 is set. 11a is held in a closed state, and by using this characteristic, the output of the voltage switching circuit 16 in the power supply circuit 15 is switched by the control means 14, so that the energization rate of the coil drive unit 12 including the coil 11b of the relay 11 is switched. Is something that changes.

  That is, the control means 14 does not use the toilet seat device body 4 by the user in order to suppress the power consumption of the relay drive unit 12 of the relay 11, that is, there is no user in the toilet room and is used for the toilet seat 2. The reason why the toilet seat 2 is kept warm, in order to save power and reduce the heating capacity of the toilet seat heater 5 because the person is not seated, is that the power supply circuit 15 of the relay drive unit 12 shown in FIG. The power supply circuit such as the nozzle drive unit of the cleaning nozzle 6 of the main body 4, the deodorization, and the fan drive unit of the drying fan is used in common, so that the configuration can be simplified and manufactured at low cost. If the output voltage of the power supply circuit 15 is kept low, the operation of the nozzle drive unit of the cleaning nozzle 6 must be avoided.

  Then, the control means 14 is a signal with no seating signal from the seating detection means 25 when the user rises from the toilet seat 2 or a human body detection means 24 (FIG. 1, FIG. 1) provided on the wall from the toilet room. 2), it is determined that the user is not using the toilet seat apparatus body 4, and the heating capacity is lowered by controlling the toilet seat heater 5, so that the toilet seat 2 is kept in a warm state. At the same time, the voltage switching circuit 16 shown in FIG. 3 is controlled in order to reduce the voltage applied to the relay driving unit 12 at this time, for example, the rated voltage V0 to V1.

  That is, when the user enters the toilet room, the human body detection signal detected by the human body detection unit 24 is input to the control unit 14. Subsequently, when the user sits on the toilet seat 2, the seating detection means 25 detects the seating and the seating signal is also input to the control means 14.

  The control means 14 includes a nozzle driving unit for the cleaning nozzle 6, a deodorizing and a fan driving unit for the drying fan, etc. in preparation for cleaning and drying the human body part after the stool by the operation of the operation unit 26 by the user. The voltage switching circuit 16 causes the SW power supply 18 included in the power supply circuit 15 to apply the rated voltage V0 to the relay drive unit 12 to which the voltage V1 lower than the rated voltage V0 is applied so as not to hinder the operation. To control.

  The operation of the voltage switching circuit 16 shown in FIG. 3 will be described together with the control time chart of the voltage switching circuit 16 shown in FIG. 4. When 100% of the rated voltage V0 is energized to the coil 11b of the relay 11, the transistor 17 Is set by series-connected resistors 20, 21, and 22 so that 100% of the DC voltage 19 of the SW power supply 18 is output when is turned on.

  Then, when the control means 14 that takes in both the detection signals of the human body detection means 24 and the seating detection means 25 outputs a high signal from the voltage switching port 23, the transistor 17 is turned on, the resistor 21 is short-circuited, and the SW power source 18 A rated voltage V0 that is 100% of the DC voltage 19 is output. On the other hand, the transistor 28 is turned on by a signal from the relay output port 27, and the rated voltage V0 is applied to the relay driver 12 and the coil 11b.

  When the user finishes washing and drying the human body part after the toilet and gets up from the toilet seat 2, the seating detection means 24 no longer detects the seating signal, and when the user leaves the toilet room, the human body detection means 24 The detection of the human body signal is lost (the toilet seat heater 5 is controlled by the control means 14 and the toilet seat 2 enters the heat retaining state), and the control means 14 that takes in both signals controls the voltage switching circuit 16 to the power supply circuit 15. The included SW power supply 18 applies a voltage V1 lower than the rated voltage V0 to the relay drive unit 12 and the coil 11b.

That is, the toilet seat 2 is in a state that needs to be kept warm, and therefore the relay 11 cannot be turned off, so that the control means 14 that has received no detection of the seating signal and the human body signal is in the power saving mode (the toilet seat 2 is kept warm). Therefore, a low signal is output from the voltage switching port 23. Then, by turning off the transistor 17 which is a voltage switching switch, the output voltage 19 of the SW power supply 18 which is set in advance by the resistors 20, 21 and 22 is reduced to some extent by the voltage V1 (arbitrary% of the rated voltage V0). The power supply rate of the relay 11 is changed and the power can be reduced by the amount reduced.

  However, as described above, in this configuration, the contact holding voltage VH of the coil 11b of the relay 11 cannot be made lower than VH, so it is necessary to set V1> VH.

  Further, when the user enters the toilet room and takes both detection signals of the human body detection means 24 and the seating detection means 25 again, the control means 14 makes the voltage switching port 23 a high signal output and is lower than the rated voltage V0. The voltage switching circuit 16 returns the voltage V1 to the normal rated voltage V0 from the power saving mode (toilet seat warming state) applied to the relay drive unit 12 and the coil 11b in accordance with the washing mode state. Can do.

  The control means 14 in the present embodiment includes a cleaning function of the toilet seat device body 4 for washing the human body part with warm water, a drying function for drying the human body part wet by washing with warm air, and an odor generated after stool. A program for overall control of a deodorizing function for deodorizing and a heat retaining function of the toilet seat 2 for lowering the heating temperature when not sitting is also stored.

(Embodiment 2)
FIG. 5 is a voltage switching circuit diagram in the leakage breaker of the toilet seat device according to the second embodiment of the present invention, and FIG. 6 is a control time chart of the voltage switching circuit. In the present embodiment, the configuration of the toilet seat apparatus main body of the first embodiment shown in FIGS. 1 and 2 is the same, and only the configuration of the control means 14 is different from that of the first embodiment. Explained.

  That is, the control means 14 is basically the same in operation and effect as the invention of the first embodiment, but particularly takes in the presence or absence of a human body detection signal from the human body detection means 24 and controls the voltage switching circuit 16. There is a configuration in which the voltage applied to the relay driving unit 12 is reduced when a signal indicating no human body detection is received from the human body detecting means 24 when the person is not using the cleaning device. Further, since the voltage switching circuit 16 is the same as that of the first embodiment, the same reference numerals are given and detailed description thereof is omitted.

  Subsequently, the operations of the voltage switching circuit 16 shown in FIG. 5 and the control time chart shown in FIG. 6 are basically the same as those of the invention of the first embodiment, and therefore different points will be mainly described.

  When the user enters the toilet room for the toilet, the human body detection means 24 outputs a human body detection signal to the control means 1, and the control means 14 incorporating the signal determines that there is a person in the toilet room. When an ON signal with human body detection is input, the control means 14 outputs the voltage switching port 23 as a high signal, and the transistor 17 is turned on, whereby the rated voltage 100% of the DC voltage 19 of the SW power supply 18 is output. On the other hand, the transistor 28 is turned on by a signal from the relay output port 27, and the rated voltage V0 is applied to the relay driver 12 and the coil 11b.

  Subsequently, when there is no person in the toilet room, a signal indicating no human body detection is input from the human body detecting means 24 as an off signal indicating no human body detection by the control means 14. When the control means 14 outputs a low signal from the voltage switching port 23 and the transistor 17 is turned off and is set by the resistors 21, 22, and 23, the output voltage 19 of the DC voltage of the SW power supply 18 decreases to some extent. The voltage V1 (arbitrary% of the rated voltage V0 of the relay 11) is switched to change the energization rate of the relay, and the power can be reduced by the reduced amount.

In this way, the control means 14 is such that the human body detection means 24 cannot detect the user in the toilet room, and reduces the voltage applied to the relay drive unit 12 when the cleaning device body 4 is not used. Even if the power is continuously supplied, the power consumption of the relay drive unit 12 can be reduced, and the power consumption of the apparatus can be reduced.

(Embodiment 3)
FIG. 7 is a voltage switching circuit diagram in the electric leakage breaker of the toilet seat device according to Embodiment 3 of the present invention, and FIG. 8 is a control time chart of the voltage switching circuit. In the present embodiment, the configuration of the toilet seat apparatus main body of the first embodiment shown in FIGS. 1 and 2 is the same, and only the configuration of the control means 14 is different from that of the first embodiment. Explained.

  That is, the control means 14 is basically the same in operation and effect as the invention of the first embodiment, but in particular, the control means 14 takes in the detection signals that the user is not seated on the toilet seat 2 from the seating detection means 25, respectively. The voltage switching circuit 16 is controlled, and when the user receives a signal not seated on the toilet seat 2, the voltage applied to the relay drive unit 12 is reduced. Further, since the voltage switching circuit 16 is the same as that of the first embodiment, the same reference numerals are given and detailed description thereof is omitted.

  Subsequently, operations of the voltage switching circuit 16 shown in FIG. 7 and the control time chart shown in FIG. 8 are basically the same as those of the invention of the first embodiment, and therefore, different points will be mainly described.

  When the user enters the toilet room for stool, the human body detection means 24 outputs a human body detection signal to the control means 14, and the control means 14 that has taken in this determines that there is a person in the toilet room. When the user is seated on the toilet seat 2, the seating detection means 25 outputs a seating detection signal, and the control means 14 that has taken in the seating detection signal inputs an ON signal to the seating detection input.

  Then, the control means 14 outputs the voltage switching port 23 to a high signal, and when the transistor 17 is turned on, a rated voltage V0 that is 100% of the DC voltage 19 of the SW power supply 18 is output. With this signal, the transistor 28 is turned on and the rated voltage V0 is applied to the relay driver 12 and the coil 11b.

  Subsequently, when the user who has finished the stool and has cleaned the human body portion by the cleaning nozzle 6 and finished drying by the drying fan stands up from the toilet seat 2, the control means 14 that takes in a signal indicating no seating detection from the seating detection means 25. Is inputted with an off signal without human body detection. When the control means 14 outputs a low signal from the voltage switching port 23 and the transistor 17 is turned off and is set by the resistors 21, 22, and 23, the output voltage 19 of the DC voltage of the SW power supply 18 decreases to some extent. The voltage V1 (arbitrary% of the rated voltage V0 of the relay 11) is switched to change the energization rate of the relay, and the power can be reduced by the reduced amount.

  In this way, the control means 14 reduces the voltage applied to the relay drive unit 12 when the seating detection means 24 can no longer detect the user with the toilet seat 2, and even if the energization is always continued, the relay drive The power consumption of the unit 12 can be reduced, and the power consumption of the apparatus can be reduced. That is, it is possible to save power by the voltage switching circuit 16 by switching the output of the voltage switching port 23 of the control means 14 according to the presence / absence of the seating detection by the seating detection means 25.

(Embodiment 4)
FIG. 9 is a voltage switching circuit diagram in the leakage breaker of the toilet seat device according to the fourth embodiment of the present invention, and FIG. 10 is a control time chart of the voltage switching circuit. In the present embodiment, the configuration of the toilet seat apparatus main body of the first embodiment shown in FIGS. 1 and 2 is the same, and only the configuration of the control means 14 is different from that of the first embodiment. Explained.

That is, the control means 14 is basically the same in operation and action as the invention of the first embodiment, but has a function of determining whether or not the operation unit 26 has been operated by a person. When the operation unit 26 of the cleaning device body 4 (corresponding to the remote control remote controller shown in FIG. 1) is not operated (until the user operates the operation unit 26 of the cleaning device body 4). In this configuration, the voltage applied to the relay drive unit 12 is set to a voltage V1 that is lower than the rated voltage V0.

  In other words, since the user uses the cleaning apparatus main body 4, the control means 14 that takes in a signal for operating the operation unit 26 is rated to the relay drive unit 12 to which the voltage V1 that has been reduced is applied. The voltage V0 is applied.

  Further, since the voltage switching circuit 16 is the same as that of the first embodiment, the same reference numerals are given and detailed description thereof is omitted.

  Subsequently, the operations of the voltage switching circuit 16 shown in FIG. 9 and the control time chart shown in FIG. 10 are basically the same as those of the invention of the first embodiment, and therefore different points will be mainly described.

  When the user enters the toilet room, sits on the toilet seat 2 and finishes the toilet, and then operates the operation unit 26 in order to perform the cleaning of the human body portion by the cleaning nozzle 6 and the drying by the drying fan, the operation signal is captured. The control means 14 controls the voltage switching circuit 16 and controls the voltage V1 that has been lowered for power saving until then, in addition to controlling the cleaning of the human body by the cleaning nozzle 6 and the drying by the drying fan. The rated voltage V0 is applied to the relay drive unit 12 that has been applied.

  That is, when the operation unit 26 is operated by a person, the control unit 14 takes in the signal and determines that the operation unit 26 is operated by the person, and outputs a high signal from the voltage switching port 23 to turn on the transistor 17 and switch SW. The output 19 of the DC voltage of the power supply 18 is made to output the rated voltage V0 of 100%. On the other hand, the transistor 28 is turned on by a signal from the relay output port 27, and the rated voltage V0 is applied to the relay driver 12 and the coil 11b.

  Subsequently, when all the operations such as the cleaning function, the drying function, and the deodorizing function of the toilet seat body 4 that the user operates by operating the operation unit 26 are finished, the control means 14 captures the end signal, Next, until the operation unit 26 is operated by the user, a voltage obtained by outputting a low signal from the voltage switching port 23 to turn off the transistor 17 and lower the DC voltage output 19 of the SW power supply 18 from the rated voltage V0. It is possible to reduce power consumption by changing the energization rate of the coil 11b of the relay 11 to V1.

  Thus, the control means 14 reduces the voltage applied to the relay drive unit 12 when the device is not operated by an operation unit such as a cleaning device by a person. The power consumption of the drive unit can be reduced, and the power consumption of the apparatus can be reduced.

(Embodiment 5)
FIG. 11 is a voltage switching circuit diagram in the leakage breaker of the toilet seat apparatus according to Embodiment 5 of the present invention, and FIG. 12 is a control time chart of the voltage switching circuit in the leakage breaker of the apparatus. In the present embodiment, the configuration of the toilet seat apparatus main body of the first embodiment shown in FIGS. 1 and 2 is the same, and only the configuration of the control means 14 is different from that of the first embodiment. Explained.

  That is, the control means 14 is basically the same in operation and action as the invention of the first embodiment, but the voltage applied to the relay drive unit 12 is rated particularly when the toilet lid 3 of the toilet seat 2 is closed. The voltage V1 is lower than the voltage V0.

  That is, the control means 14 opens the toilet lid 3 by the opening / closing drive unit when the human body detection signal from the human body detection means 24 that detects the human body that has entered the toilet room is opened, and from the human body detection means 24 when the person leaves the toilet room. This is a configuration for performing automatic opening / closing control in which no human body detection signal is received and the toilet lid 3 is closed by an opening / closing drive unit.

  The toilet lid opening / closing detection means 29 detects the opening / closing of the toilet lid 3 in conjunction with the opening / closing drive unit of the toilet lid 3 and outputs an opening / closing signal to the control means 14. Therefore, the control means 14 takes in the toilet lid opening / closing signal of the toilet lid opening / closing detection means 29 and controls the voltage switching circuit 16 so that the voltage applied to the relay drive unit 12 is the rated voltage V0 when the toilet lid is closed. The voltage V1 is further reduced, and when the toilet lid is open, the voltage V1 that has been applied to the relay drive unit 12 so far is set to the rated voltage V0.

  Further, since the voltage switching circuit 16 is the same as that of the first embodiment, the same reference numerals are given and detailed description thereof is omitted.

  Next, the operations of the voltage switching circuit 16 shown in FIG. 11 and the control time chart shown in FIG.

  When the user enters the toilet room for stool, the human body detection means 24 outputs a signal indicating the presence of human body detection to the control means 14, and the control means 14 incorporating the signal determines that there is a person in the toilet room. . And the control means 14 which took in this signal with a human body detection opens the toilet lid 3 by controlling an opening / closing drive part. The toilet lid opening / closing detection means 29 interlocked with the opening / closing drive unit outputs a toilet lid opening signal to the control means 14, and the control means 14 taking in this signal controls the voltage switching circuit 16.

  That is, the control means 14 outputs the voltage switching port 23 to a high signal, and when the transistor 17 is turned on, a rated voltage V0 that is 100% of the DC voltage 19 of the SW power supply 18 is output. With this signal, the transistor 28 is turned on, and the rated voltage V0 is applied to the relay drive unit 12 and the coil 11b.

  Subsequently, when the user who has finished the stool and has finished cleaning the local area of the human body with the cleaning nozzle 6 and drying with the drying fan rises from the toilet seat 2 and exits the toilet room, a signal indicating no human body detection from the human body detecting means 24 is received. The control means 14 that enters the control means 14 and takes in this signal controls the opening / closing drive part of the toilet lid 3 to close the toilet lid 3.

  The control means 14 that has received the toilet lid closing signal from the toilet lid opening / closing detection means 29 that has detected the closed state of the toilet lid 3 outputs a low signal from the voltage switching port 23 and the transistor 17 is turned off to turn off the resistor 21. , 22 and 23, the output voltage 19 of the DC voltage of the SW power supply 18 is switched to a voltage V1 that is lowered to some extent (a voltage that is an arbitrary% of the rated voltage V0 of the relay 11), and the energization rate of the relay is increased. The electric power can be reduced by the reduced amount.

  Thus, the control means 14 reduces the voltage applied to the relay drive unit 12 when the toilet lid 3 is in the closed state, and reduces the power consumption of the relay drive unit even if it is always energized, Power saving of the apparatus can be achieved.

  In the present embodiment, the control means 14 captures the opening and closing signals by the automatic opening / closing of the toilet lid 3, but the toilet lid opening / closing detection means 29 detects the manual opening / closing of the toilet lid 3 and the control means 14 may be output.
