Abstract

PROBLEM TO BE SOLVED: To utilize a storage region effectively, and to realize the smooth conservation and read of data in a sanitary flushing device, in which various kinds of set data must be stored. SOLUTION: When a power supply for the sanitary device is turned on, the set state of a tact switch 160 stored in a back-up RAM is read, and the state of the switch is set at on as initialization at the time of an unset state (a step S316). When the tact switch 160 is depressed, the state of the switch is reset at off, and the fact that the state of the switch is changed over to off is stored in the back-up RAM, but nothing is written to the back-up RAM so far as the tact switch 160 is depressed (a step S320). Accordingly, when the power supply is stopped as the tact switch 160 is left as it is not depressed and the power supply is turned on again, the set state of the tact switch 160 is set at on as initialization again (a step S316).

The sanitary device of the present invention is provided with sanitary function means for washing and drying a human body, and the temperature of the washing water, the drying temperature and the like of the sanitary function means are detected by the state detecting means. The detection data detected by the state detection means is stored in the nonvolatile storage unit of the state storage means. Since the non-volatile storage unit stores the detection data even when the sanitary device is not energized, the detection data can be used as data for analyzing the cause of failure or the like.

In this sanitary device, as the state storage means, a means for selectively storing the detected data in the nonvolatile storage unit when the detected data is predetermined data may be used. According to the sanitary apparatus provided with such a state storage unit, when the detected data is the predetermined data, the detected data is selectively stored in the non-volatile storage unit.

The state detecting means is a timer means for outputting a clock signal at predetermined time intervals. Even when the state storage means is not energized, the non-volatile storage section stores the timer means in the non-volatile storage section. It is also desirable to employ a configuration using a cumulative time storage means for storing the clock signal from the CPU as a cumulative measurement time. In such a sanitary device, the timer means outputs a clock signal to the accumulated time storage means at predetermined time intervals. The cumulative time storage means stores the clock signal in the nonvolatile storage unit as a cumulative measurement time. Accordingly, the measurement time is stored in the non-volatile storage unit and is not lost even when the sanitary device is not energized, and is used when the energization is restored, so that the maintainability is excellent.

The state detecting means is a use detecting means for outputting a signal every time the sanitary function means is used. Even when the state storing means is not energized, the non-volatile storing section stores the state storing means. It is also preferable to use a cumulative number storing means for storing a signal from the use detecting means as a cumulative use number. According to such a configuration, each time the use detecting unit uses the sanitary function unit, a signal is output and input to the cumulative number storage unit. The cumulative number storage means stores the number of times of use as a cumulative number of times of use in the non-volatile storage unit. It is excellent in maintainability.

As the use detecting means, a seat detecting means for detecting a state of sitting on the toilet seat may be used. According to the sanitary device having such a configuration, since the number of times of use is detected by using the seating detecting means as the use detecting means, a highly reliable number of times of use can be obtained.

In the sanitary apparatus having the above configuration, it is preferable that the sanitary apparatus further includes an output unit for outputting the detection data stored in the nonvolatile storage unit to the outside.
Since the detection data in the non-volatile storage unit is output to the outside via the output unit, the necessity of maintenance can be known, and the safety and maintainability of the sanitary function unit can be improved.

It is also preferable that the sanitary function means is provided with a deodorant which is consumed in a predetermined time.
By using a deodorant requiring high maintenance as a detection target as a sanitary function means, it is possible to further improve maintainability.

Timer reservation button 1 for setting 3 to off for a predetermined time
3 m is provided.

Further, the toilet seat 15 is provided with a seating sensor 15a for detecting the seating on the toilet seat 15. As the seating sensor 15a, for example, a sensor that measures a change in capacitance of the toilet seat heater 53 on the surface of the toilet seat 15 to detect the presence or absence of seating, or a pressure sensor can be used. The setting state of the sanitary washing device 10 is displayed by a display lamp 13B including an LED or the like. The display lamp 13B has various display functions for notifying various operating states, abnormalities, and the presence / absence of timer reservation.

Next, a description will be given of a process performed by the electronic control unit 100 for determining various abnormal states occurring in the sanitary washing device 10.

First, the abnormality determination processing of the seat sensor 15a will be described. FIG. 4 is a flowchart for explaining the abnormality determination routine of the seat sensor 15a. This routine is executed by interruption processing at predetermined time intervals. First,
In step S12, the detection voltage Vs based on the output from the seat sensor 15a is read. Subsequent step S1
At 4, the abnormality determination flag Fss is determined, and if the abnormality determination flag Fss is 0, the process proceeds to step S16. This abnormality determination flag Fss is
Is a flag that is set to 1 when it is determined that is abnormal.

In the following step S16, it is determined whether or not the detected voltage Vs is equal to or higher than the predetermined voltage Vsc. If the detected voltage Vs is equal to or lower than the predetermined voltage Vsc, it is determined that the vehicle is not in the seated state, and the process is temporarily terminated. On the other hand, if it is determined in step S16 that the voltage is equal to or higher than the predetermined voltage Vsc, that is, if it is determined that the vehicle is in the seated state, the seating counter Cs is incremented in step S18.

In the following step S20, the seating counter C
When s exceeds a predetermined time Csc (Csc is a value corresponding to, for example, 2 hours), an abnormality determination flag Fss indicating an abnormal state of the seat sensor 15a is set to 1 in step S22. The abnormality determination flag Fss is used for determination in another routine, and when it is set to 1, the cleaning operation, the drying operation, the deodorizing operation, and the like are forcibly turned off. Then, in step S24, the fact that the abnormality determination flag Fss has been set to 1 is indicated by the backup RAM1.
07 is stored. That is, if a signal indicating that the user is seated is output from the seating sensor 15a and the signal continues to exceed the normal seating time, the seating sensor 15a
Is determined to be abnormal. Such a seating sensor 15a
The abnormal state is used as failure detection data at the time of later repair, thereby facilitating failure detection.

On the other hand, in step S14, when the abnormality determination flag Fss is determined to be 1, that is, when it is determined that the seat sensor 15a is abnormal, when the seat sensor 15a outputs a normal value, That is, from step S34
When the condition of step S42 is satisfied, a process of canceling the abnormality determination of the seat sensor 15a is executed. That is,
In step S32, the determination of the return flag Fsr is performed. The return flag Fsr is a flag that is set to 1 after the seat sensor 15a is determined to be abnormal, that is, when one return condition is satisfied.

In the following step S34, when it is determined that the detection voltage Vs is equal to or lower than the predetermined voltage Vsc, the return flag Fsr is set to 1. When the return flag Fsr is set to 1, the process proceeds to step S38 in the determination of step S32. In step S38, the detection voltage Vs is determined, and the detection voltage Vs is set to the predetermined voltage Vs.
When it is determined that it is not less than sc, the abnormality determination flag Fss and the return flag Fsr are reset to 0 in step S40. Thereby, the sanitary washing device 10 returns to the original normal washing control in the processing of another routine.

That is, even if the seating sensor 15a detects a seating state for two hours or more and is determined to be abnormal (steps S16 to S24), after the user leaves the seat (steps S34 and S36), When the seated state is detected, it is determined that the seating sensor 15a is not abnormal (step S38), and the state is returned to the original state.
They avoid false detections.

Therefore, if the seating sensor 15a becomes abnormal, even if the seating sensor 15a recovers normally, the fact is stored in the backup RAM 107, so that the seating sensor 15a and the like can be easily repaired based on this. In addition, the fact that the seating sensor 15a is abnormal is
07, the information is not lost even during a power failure. It should be noted that storing the elapsed time of use, the number of times of use, and the like of various functional units at the time of occurrence of an abnormality can be used as failure finding data.

Next, an abnormality determination process performed by the electronic control unit 100 when the hot water thermistor 28a detects a predetermined temperature or higher will be described with reference to the flowchart of FIG.

First, at step S52, the detected temperature TMs of the hot water thermistor 28a is read. In the following step S54, the temperature T detected by the thermistor 28a for hot water is detected.
It is determined whether Ms is equal to or higher than a predetermined temperature TMsc,
If the temperature is equal to or lower than the predetermined temperature TMsc, the process ends.

On the other hand, if the detected temperature TMs of the hot water thermistor 28a is equal to or higher than the predetermined temperature TMsc in step S54, the solenoid valve 24 is closed in step S56. This prohibits high-temperature water discharge at a predetermined temperature or higher from the cleaning nozzle 40.

As another means for preventing high-temperature water discharge from the washing nozzle 40, a bypass passage (not shown) for bypassing the washing nozzle 40 is provided, and a bypass valve is provided in the bypass passage. By opening, high-temperature water may be discarded through the bypass passage.

In the following step S58, detection data or control data of other various states temporarily stored in the RAM 106 is read. As the detection data or control data, the setting state of the operation button 13A, the detected temperature peak value THs of the hot water thermistor 28a, the seating sensor 15
Data such as a signal indicating a seating state a and a signal indicating whether or not water is discharged in a state where the solenoid valve 24 is opened.

In the subsequent step S60, the fact that the detected temperature TMs of the hot water thermistor 28a is equal to or higher than the predetermined temperature is stored in the backup RAM 107, and the detection data and control data of various states read in step S58 are also stored in the backup RAM 107. I do. In the next step S62, the fact that a high temperature equal to or higher than a predetermined value is detected is displayed on the display lamp 13B, and the fact is notified. Since this detection data is continuously stored even after the return of the power supply, it is possible to continuously set the water discharge prohibition state based on this data.

According to this process, when the hot water thermistor 28a detects a predetermined temperature or higher, the fact is stored in the backup RAM 107, and the detected data and control data at that time are stored. Discovery is easier.

That is, of the detection data and the control data stored in the backup RAM 107, depending on the setting state of the operation button 13A, whether or not the buttocks cleaning button 13a or the bidet cleaning button 13b is on and the stop button 13c are pressed. Whether or not the drying button 13d
It is possible to know at any time or state from the hot water thermistor 28a whether or not a temperature equal to or higher than a predetermined temperature has been detected from the control data such as ON / OFF.

Also, based on the seating detection data of the seating sensor 15a, it is determined whether or not a failure has occurred during seating on the toilet seat 15, and based on the detected temperature peak value THs of another hot water thermistor 28a and other data, It is possible to know whether or not the failure is the failure 28a itself.

Further, based on a signal from the float switch 31, it is determined whether or not the hot water thermistor 28a has failed when the heat exchanger 30 is full, and whether or not the control amount to the cleaning heater 29 causes heating control. You can know.

Next, processing requiring maintenance of the sanitary apparatus, for example, maintenance processing of a dust filter of an indoor heating unit, a dust filter of a deodorizing unit, a deodorant, etc. will be described. Here, a description will be given of an example of a notification process for prompting replacement of a deodorant or the like. The deodorant is consumed after a predetermined period of time and needs to be replaced. However, this process is performed when a predetermined time (about seven years) has elapsed since the deodorant was loaded, or when the deodorizing operation time was predetermined. This is a process for prompting the exchange when the time has elapsed.

As shown in FIG. 6, a deodorant unit 150 is provided on the side of the sanitary washing device 10. The deodorant unit 150 has a storage recess 151, and a deodorant 152 is stored in the storage recess 151, and is loaded by closing with a lid 153. Further, a reset switch 154 is provided on the lid 153, and the reset switch 154 outputs a reset signal to the electronic control unit 100 when the deodorant 152 is replaced.

The notification process of the replacement time of the deodorant 152 is executed by a routine shown in a flowchart shown in FIG. This process is repeatedly executed after a reset signal is input from the reset switch 154 to the CPU 102 and the initialization process is performed. In the initialization process, the RAM 10
6 or a counter stored in the backup RAM 107.

After the execution of the initialization processing, step S102
, The first counter CM1 is incremented, and in step S104, it is determined whether the first counter CM1 exceeds a predetermined value CM1c. The predetermined value CM1c is set to, for example, a value corresponding to 24 hours. When an affirmative determination is made in step S104, the process proceeds to step S106. Step S1
At 06, the value of the second counter CM2 is read from the backup RAM 107, and further the second counter CM2 is incremented at step S108, and the value of the second counter CM2 is written to the backup RAM 107 at step S110.

In the following step S112, it is determined whether or not the second counter CM2 has exceeded a predetermined value CM2c. The predetermined value CM2c is set to a value corresponding to the time required for maintenance, and for example, when notifying the replacement time of the deodorant, a value corresponding to seven years is set.

If it is determined in step S112 that the value of the second counter CM2 has exceeded the predetermined value CM2c, the flow advances to step S114 to proceed to step S114.
7, and the display lamp 13B is turned on in step S116.

By the notification of the display lamp 13B,
The necessity of replacement of the deodorant 152 can be known. When the deodorant 152 is replaced, a reset signal is output from the reset switch 154. The reset switch 154 is connected to the lid 1 of the deodorant unit 150.
Since the reset signal is output at the same time as the deodorant 152 is provided, the reset operation is not required. In addition,
The reset switch 154 may be substituted by specially operating a switch of a remote control or an operation unit.

According to the above embodiment, the necessity of the replacement of the deodorant 152 or the like which needs to be replaced in a predetermined period is notified, so that the replacement of the deodorant 152 is not forgotten. In the above processing, the second counter CM2
Is stored in the backup RAM 107 and is not reset when a power failure occurs. Therefore, even if there is a power failure or the like during use, it is possible to know the exact replacement time.

Next, as another embodiment for notifying the maintenance time, a process of obtaining based on data on the number of times of sitting will be described with reference to the flowchart of FIG. That is, since the number of times of sitting on the toilet seat 15 matches the number of times the deodorant is used, the maintenance time is obtained from the data.

In FIG. 8, first, the first step S2
At 00, the seating flag Fsw is determined. The seating flag Fsw is a flag that is set to 1 when the seating sensor 15a is turned on, and is 0 in the first processing, so that the process proceeds to step S202. Step S202
Then, it is determined whether or not the seat sensor 15a is turned on. This determination process is performed based on the detection voltage Vs from the seat sensor 15a. This step S
At 202, if it is determined that the detected voltage Vs is equal to or higher than the predetermined voltage Vsc and the user is seated, the process proceeds to step S204,
The seating flag Fsw is set to 1. Step S206
Then, the seating counter Ns indicating the number of times of seating is incremented. The value of the seating counter Ns is stored in the backup RAM 107, and the value is incremented. In the following step S208, it is determined whether or not the seating counter Ns has exceeded a predetermined number of times Nsc. If the determination is negative, the process is temporarily terminated.

In step S200, since the seating flag Fsw is set to 1 in step S204, the process proceeds to step S210, and it is determined whether a predetermined time has elapsed since the seating flag Fsw was turned on.

If it is determined in step S210 that the predetermined time has elapsed, then in step S212, the seating flag Fs
w is reset to zero. Thus, step S210
The reason why the seat is not determined to be seated until a predetermined time has elapsed after the seating sensor 15a is turned on is that reseating on the toilet seat 15 is not detected as a new seat.

In the repetitive processing of this processing, step S2
If it is determined at 08 that the seating counter Ns has exceeded the predetermined number of times Nsc, the fact is stored in the backup RAM 107 in step S220, and furthermore, in step S22.
At 2, the display lamp 13B is turned on to indicate that the seat has been seated a predetermined number of times or more.

Therefore, it is possible to know the replacement time of the deodorant or the like from the number of times of seating, and furthermore, the seating counter Ns
Is stored in the backup RAM 107,
It is not reset by a power failure or the like. The replacement time may be notified by AND or OR of the seating counter and the use time.

Next, as another embodiment, the sanitary washing device 1
The input setting process of the operation button 13A in the 0 operation unit 13 will be described. This process is a process in which the setting state of the operation button 13A of the sanitary washing device 10 is not lost even when a power failure occurs.

This processing can be suitably performed using a so-called tact switch 160 shown in FIG. FIG.
FIG. 4 is a cross-sectional view showing the periphery of a switch mechanism 161 using the tact switch 160. The tact switch 160 is fixed on a printed board 162, and a case 163 is installed above the tact switch 160 in parallel with the printed board 162. The case 163 above the tact switch 160 has an opening 163a.
In addition, a key top portion 160a for operating the tact switch 160 is provided. This key top part 160
a is the display sheet 16 adhered to the upper surface of the case 163.
4 is fixed. The display sheet 164 has a switch operation unit 164 representing an operation unit of the tact switch 160.
a is displayed. Therefore, the switch operation unit 16
When the key 4a is pressed, the tact switch 160 is switched via the key top 160a. A display lamp 165 that is turned on and off by the switching action of the tact switch 160 is fixed to the printed circuit board 162 on the side close to the tact switch 160.

In the switch mechanism 161 having such a configuration,
Since the display sheet 164 is in close contact with the case 163,
There is no gap around the opening 163a, which is suitable for places requiring high waterproofness such as toilets.

The tact switch 160 is normally used at a place where switching is temporarily set, but when the power is cut off due to a power failure or the like, the state is erased. In this embodiment, while taking advantage of the above-described water resistance, the backup RA
M107 and the process of FIG. 10 are executed to constitute a self-holding switch.

Next, the processing of FIG. 10 will be described. In FIG. 10, when the power is turned on, this processing is executed. First, in the first step S302, the backup R
The setting state of the tact switch 160 is read from a specific address of the AM 107. In the following step S304, it is determined whether the switch data is on, off, or not set. Then, according to the determination in step S304, steps S312, S314, S316
Is selectively executed, and the display lamp 13B is displayed based on the setting contents.

The following steps S320 to S33
The processes up to 8 are repeated each time the tact switch 160 is pressed. That is, in step S320, it is determined whether or not the tact switch 160 has been pressed. If it is determined that the tact switch 160 has been pressed, the process proceeds to step S322. In the following step S322, it is determined whether the tact switch 160 is currently on or off.
If it is in the ON state, the fact that it has been turned off is stored in the backup RAM 107 (step S324), and after the display lamp 13B is turned off (step S32).
6), and set to the off state (step S328). On the other hand, if it is determined in step S322 that the tact switch 160 is off, the backup RAM 10
7 (step S334), display lamp 13
The lighting process of B (step S336) and the setting process to the ON state (step S338) are executed.

Therefore, according to the above embodiment, the setting contents of the tact switch 160 are stored in the backup RAM 107, and the setting state can be read out even when the power is cut off due to a power failure or the like, and the original state can be restored.

The tact switch 160 of the sanitary washing device 10 can be used in various places where the setting state of the user is desired to be stored. For example, the tact switch 160 can be set in two states such as turning on / off a heater for a toilet seat. In addition to the above, the present invention can also be applied to a device that switches between three or more setting states, such as a water discharge temperature setting button. That is, the water discharge temperature setting button 1
3g is a switch used to sequentially switch the heater off → low temperature → medium temperature → high temperature → heater off.

In the above embodiment, the tact switch is used as the self-holding type switch. However, the present invention is not limited to this, and can be applied to various switches as long as the switch switches every time a pulse signal is input. . In addition, the data set by the switch can be applied to various data as long as the control conditions of the sanitary washing device are set in addition to the water discharge temperature, such as the water force of the water discharge nozzle, the nozzle position, and the massage. It can be applied to setting of washing, move washing, deodorizing on / off, operation on / off, and the like.

Next, an embodiment in which the backup RAM 107 is applied to the timer reservation processing of the sanitary washing device 10 will be described. The timer reservation process is suitably applied as a process for stopping at least one of the toilet seat heater 53, the cleaning heater 29, and the indoor heating heater (not shown) for a predetermined time, for example, nighttime when the number of times of use is small. can do.

Timer reservation button 13 of sanitary washing device 10
When a predetermined time is set for m, the input timer reservation data is stored in the RAM 106, and the timer reservation flag Ft indicating that the timer has been reserved is stored in the backup RAM 107 at 1. Such timer reservation data is stored in the toilet seat heater 5 based on a routine (not shown).
3 is used for the OFF setting process.

On the other hand, when the power is cut off due to a power failure or the like, the timer reservation function is disabled and deleted because the time cannot be measured. Data, that is, the timer reservation flag F
Since the data of t is stored in the backup RAM 107, it is used by the following processing.

That is, when the power is turned on after the power failure of the sanitary washing device, the power failure recovery process shown in the flowchart of FIG. 11 is executed. In the first step S352, the timer reservation flag Ft is read from a specific address in the backup RAM 107. In a succeeding step S354, the timer reservation flag Ft is determined. This step S
If it is determined by the flag determination of 354 that there is no timer reservation, the present process is terminated without blinking the timer reservation display lamp 13B. On the other hand, if it is determined that the timer reservation has been made, the process proceeds to step S356, in which the timer reservation display lamp 13B flashes to indicate that the timer reservation function has been disabled due to the power failure, and the user resets or resets. Prompt.

In the following step S358, it is determined whether or not the user has input the timer reservation button 13m, and if so, the flow proceeds to the next step S360. In step S360, it is determined whether the input data from the timer reservation button 13m is a timer setting signal or a timer reservation canceling signal. If the input data is a timer setting signal, the process advances to step S362 to turn on the timer reservation display lamp 13B. Light. On the other hand, if it is determined in step S360 that the signal is a timer reservation release signal, step S3
At step 64, the display lamp 13B is turned off, and
At 366, the timer reservation flag Ft is reset to 0.

Therefore, when the power is turned on after a power failure,
If the timer is reserved before the power is turned off, the display lamp 13B blinks to indicate that the timer reservation is to be set. Therefore, as in the case where a reservation is made to stop energization of the toilet seat heater 53 at night, useless power may be consumed by ignoring that the timer reservation function is disabled. Absent. On the other hand, if the timer has not been reserved before the power failure, the display lamp 13B does not blink, so that even if the timer has not been reserved, the display lamp 13B blinks and an annoying display prompting the operation may be displayed. Nor.

Note that, in the configuration for performing timer reservation by operating the remote controller in the sanitary washing device 10 equipped with a battery-operated remote controller, the timer reservation data in the remote controller is not erased due to the power failure. Therefore, it only has to be sent to the sanitary washing device itself,
There is no need to perform any troublesome setting operations, and it is more convenient to use.

Next, an embodiment having a function of operating the setting state of the sanitary washing device 10 with a remote controller will be described.
In the sanitary washing device 10, when a plurality of the same type are installed in a public facility or the like in a simultaneous manner, it is necessary to prevent the sanitary washing device 10 from being operated by a signal from an adjacent remote controller. In the present embodiment, the identification code for identifying the sanitary washing device 10 can be easily set or changed regardless of the installation location.
Backup R as setting means for remote control or operation unit
AM107 is used.

This process includes a process for setting an identification code in the sanitary washing device main body and a process for setting the same identification code on the remote controller in response to the process.

First, the setting of the identification code on the sanitary washing device body will be described with reference to the flowchart of FIG. This routine is started when the power is turned on while pressing the bidet cleaning button 13b. First step S402
Then, a standby process in the input mode is performed. From this state, the ass washing button 13a, the drying button 13d, the stop button 1
When any one of the buttons 3c is pressed, the process proceeds to the next step S404, and a determination is made as to which button has been pressed.

In the determination processing of step S404, the identification code corresponding to the selected button is set in step S406,
The selection is made in S408 and S410. That is, when the buttocks cleaning button 13a is pressed, the standard code C0 is selected in step S406, and when the drying button 13d is pressed, the specific code C1 is selected in step S408,
When the stop button 13c is pressed, the specific code C2 is selected in step S410. Note that these codes are stored in the ROM 104 in advance, and are selectively read out when the corresponding button is pressed. In subsequent step S412, when it is determined that the confirm button 13k has been pressed, the selected identification code is stored in a predetermined address of the backup RAM 107 in step S414.

On the other hand, the setting of the identification code on the remote control side is as follows.
The processing is executed in substantially the same processing as the above processing. That is, when a battery is inserted into the battery box of the remote control while pressing the bottom cleaning button of the remote control, the remote control code setting mode is set. From among the buttons corresponding to the identification codes assigned in advance, the same button as the button pressed on the sanitary washing device main body is pressed, and then the confirmation button is pressed. This allows
The same identification code set in the sanitary washing device main body is stored in the backup RAM of the remote controller.

As described above, by selecting 1 from a plurality of pre-assigned identification codes on the sanitary washing device main body and the remote controller and setting the same identification code, a plurality of identification codes are set to be adjacent to each other. Sanitary washing device 10
It is possible to set an identification code different from the one set in. The identification code set in this way is stored in the backup RAM 107 and is not deleted even at the time of a power failure.

According to the above-described embodiment, when the sanitary washing device 10 equipped with a remote controller is installed in a public facility or the like in a simultaneous manner, the setting is made such that adjacent ones are set to different identification codes at the installation site. Easy to do.
Therefore, as in the related art, on the production line of the sanitary washing device or at the installation site, it is troublesome to cut the pattern in the control device of the sanitary washing device main body, add a jumper wire or a resistor, and set an identification code. Unnecessary work becomes unnecessary.

In the above embodiment, the identification code is set for both the sanitary washing device main body and the remote controller. However, by adopting the following configuration, the setting can be more easily performed only with the sanitary washing device main body. Can be. That is, the power is turned on while pressing the bidet cleaning button 13b of the operation unit 13 of the sanitary washing device 10, and the process proceeds to the identification code setting process of the remote controller. When transmission is performed from the remote controller, the identification code included in the transmission signal is determined, and the determined identification code is stored in the backup RAM 107 of the sanitary washing device main body.

Therefore, if one is selected from a plurality of remote controllers for which the identification code is set in advance and transmitted from the remote controller, the sanitary washing device body extracts the identification code based on the signal received from the remote controller. Since the data is stored in the backup RAM 107 of the sanitary washing device main body, the operation of setting the identification code with the sanitary washing device 10 and the remote controller is not required, and the operation is further simplified. Note that one of the operation units 13 of the sanitary washing device 10 may be selected and transmitted to the remote controller. In addition, the setting code of the sanitary washing device 10 and the remote controller can be set using a special external input device.

Next, as shown in FIG. 13, an embodiment applied to a leakage control device of the sanitary washing device 10 will be described. As shown in FIG. 13, the electronic control unit 201 of the electronic control device 200 includes a power supply circuit unit 21 connected to a commercial power supply V.
Powered by 0. The power supply circuit section 210
This is a constant power supply circuit that converts a commercial power supply of V to a DC voltage of 5 V.

A heater driving section 211 is connected to the output processing circuit of the electronic control section 201. The heater drive unit 211 drives the heater drive circuit 222. The heater drive circuit 222 includes a transistor 222a, a relay contact 223a, and a relay coil 223b. When a drive signal is output from the electronic control unit 201 to the heater drive unit 211, the transistor 222a is turned on, the relay coil 223b is excited, and the relay contact 223a is turned on and off. Due to the intermittent connection of the relay contact 223a, the power supply to the cleaning heater 29 is controlled via the connection lines L1 and L2 of the commercial power supply V, and the hot water in the heat exchanger 30 is maintained at a predetermined temperature. Note that the cleaning heater 29 is connected to the connection lines L1 and L2 of the commercial power supply V by the interruption coil 252 of the earth leakage interruption device 240.
a.

Next, the heater temperature control process executed by the electronic control unit 201 will be described with reference to the flowchart of FIG. First, the target set temperature Tm set by the water discharge temperature setting button 13g is read (step S5).
02) Subsequently, the detected temperature TMs from the hot water thermistor 28a is read (step S504), and the detected temperature TMs is compared with the target set temperature Tm. Step S506),
A drive signal is output to the heater drive unit 211 (step S5).
08: Turn on / off the cleaning heater 29 to execute the feedback control so as to reach the target set temperature Tm. With this control, the hot water in the heat exchanger 30 is controlled so as to reach the target set temperature Tm, and the cleaning water is jetted from the cleaning nozzle 40.

Further, the earth leakage interrupting device 240 shown in FIG.
Is a device for preventing electric leakage of the cleaning heater 29, an AC device 241 for detecting an unbalanced state of current flowing through the connection lines L1 and L2, and an electric leakage control unit 204 for detecting electric leakage based on the output of the AC device 241. , And a shutoff circuit 250. The cutoff circuit 250 includes a transistor 251 and a relay circuit 252. The relay circuit 252 includes a breaking coil 252a, and relay contacts 252b and 252c that are opened by exciting the breaking coil 252a.

With the configuration of the earth leakage interrupter 240, when an unbalanced current flows through the connection lines L1 and L2,
The leakage control unit 204 detects the leakage state via the AC device 241 and outputs a drive signal to the transistor 251 to excite the cutoff coil 252a. As a result, the relay contacts 252b and 252c are opened at the same time, and the power supply to the cleaning heater 29 is cut off to prevent an electric leakage. It should be noted that even if the earth leakage interrupting device 240 performs an interrupting operation,
The connection point of 0 corresponds to the relay contacts 252b and 252c.
Since it is on the commercial power supply V side, the power supply to the electronic control unit 201 is not stopped. Therefore, the electronic control unit 201
Is supplied with electricity even after the earth leakage cutoff operation, and the operation is guaranteed. Therefore, a process of storing the operation state of the hot water / nozzle control device 14 at the time of earth leakage can be executed.

The electronic control unit 201 stores a signal indicating that a leakage detection signal has been input from the leakage control unit 204 in a backup RAM (not shown). At this time, other data, for example, information such as presence / absence of seating, water discharge state, and the float switch 31 are stored. These pieces of information become powerful data on the state in which the electric leakage has occurred, and can be used for finding a failure point at the time of repair.

That is, based on the seating detection signal from the seating sensor 15a, it is possible to know whether or not a leakage has occurred during the heating of the cleaning heater 29. Cleaning heater 29
Is frequently energized during spouting. It is possible to determine whether the cleaning heater 29 is generated at the time of energization or whether it is generated due to another cause by determining whether the cleaning heater 29 is generated during standby or whether the leakage is generated during discharging water.
This can help improve the reliability of the cleaning heater 29. Further, when the occurrence of a serious failure such as an electric leakage is stored in the backup RAM 207, when the power is turned on next time, it is possible to judge the content and to make at least the electric leakage failure not function. It is.
