Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet apparatus having a function of heating a toilet room.

[0002]

2. Description of the Related Art In recent years, various devices have been devised to enhance the feeling of use of toilets. For example, a heating device that blows warm air to heat a toilet room, and a sanitary washing device that blows washing water to a local part of a human body to perform local washing have been proposed. In addition, various devices for local cleaning in the sanitary cleaning device are driven by remote control so that the user sitting on the toilet can perform local cleaning without taking an unreasonable posture such as twisting the body. . In addition, the above-described heating device, for example, a warm air heater is incorporated in a sanitary washing device, and the warm air heater is driven in accordance with the temperature in the toilet room detected near the toilet. In addition to the above-described local cleaning and indoor heating, a so-called heated toilet seat in which a heater is incorporated in the toilet seat has been widespread in order to achieve more comfort when using the toilet.

[0003]

When heating the toilet indoors, the warm air heater is driven in accordance with the toilet indoor temperature so as to reach the target temperature. However,
Toilet users sometimes feel uncomfortable with insufficient heating or excessive heating. This is presumably because the above-mentioned heating toilet seat, a washing water tank for local washing, and the like exist around the toilet, and due to these influences, a difference occurs between the actual toilet room temperature and the detected room temperature. In addition, if the detector (sensor) of the toilet room temperature is separated from the toilet, the influence of the heating toilet seat or the like can be reduced. However, a member only for installing the sensor is required, and a power supply and a signal output line for driving the sensor are separately required. For this reason, even if the sensor was simply installed away from the toilet, there was a problem associated with it.

In addition, when retrofitting a heating device or the like to an installed toilet, the heating device cannot be retrofitted due to limited space in the toilet room or interference with an existing sanitary washing device. There was also.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to heat a tray room without giving a user an uncomfortable feeling, and to increase the degree of freedom of retrofitting a heating device or the like.

The heating device for heating the toilet room is controlled in accordance with the temperature in the toilet room detected by the temperature detecting means provided in the remote control device.

[0007] In the first toilet apparatus of the present invention having the above configuration, the temperature in the toilet room for controlling the thermal equipment is:
Detected at the remote control. Since the remote control device is located in a place suitable for the operation of a toilet bowl user in the toilet room, it is relatively far from the toilet bowl and is located at substantially the center in the vertical direction in the toilet room. For this reason, the temperature of the toilet room is detected relatively without being affected by the cooling water near the toilet floor or the warm air near the toilet ceiling, or the washing water tank or washing water piping in the heated toilet seat or the sanitary washing device installed in the toilet. it can. As a result, according to the first toilet apparatus of the present invention, since the average temperature in the toilet room is accurately detected and the thermal equipment is controlled, the toilet room can be heated without giving a user a sense of incongruity. it can.

In addition to being able to heat without heating, there are the following advantages. In this toilet device, since the control signal of the heating device according to the toilet room temperature is generated by the remote control device and output to the heating device, the control device does not need to generate this control signal by itself, but simply generates this control signal. What is necessary is just to control a thermal appliance based on a control signal. More specifically, the control timing of the on / off control of the thermal equipment and the state of control after the power is turned on, for example, whether or not rapid heating or slow heating can be performed, are controlled by a remote control device. For this reason,
The calculation load on the control device side can be reduced and the control can be simplified.

In addition, when slow heating is sufficient because the temperature difference is relatively small, a control signal for slow heating control of the heating device can be generated on the remote control device side and output to the control means. Therefore, the calculation load on the control device side can be reduced and the control can be simplified.

According to a third aspect, in the above-mentioned second toilet apparatus of the present invention or in the first to second aspects, the output means of the remote control device controls the output frequency of the control signal to the control means. It has changing means for changing.

According to the third aspect, for example, once the control signal relating to the control timing of the thermal equipment, for example, the ON signal is output from the remote control device, the same ON signal can be prevented from being output repeatedly. . Therefore, by refraining from unnecessary output of the control signal, it is possible to suppress consumption of electric energy required for outputting the control signal. Therefore, when the remote operation device uses a battery as a power source, the life of the battery can be extended.

In a fourth aspect based on the third aspect, the changing means has a clock circuit for measuring a current time, and has means for changing the output frequency according to the current time.

In a fifth aspect based on the third aspect, the changing means has means for changing the output frequency in accordance with the state of the detected temperature change.

According to the fourth or fifth aspect, the room temperature during the daytime when the temperature in the toilet room naturally becomes relatively high (eg, late spring, summer or early fall), or the detected room temperature is rising. In such a case, energy consumption can be more effectively suppressed by reducing the output frequency of the control signal. And in these aspects, the life of the battery used as the power source of the remote control device can be further extended.

According to the third toilet device of the present invention having the above configuration, since the remote control unit has the mounting portion in advance, it is possible to perform various operations without being restricted by the installation space or interference with the sanitary washing device. External devices can be easily retrofitted.

The third toilet apparatus of the present invention having the above configuration can also adopt the following modes. According to a first aspect, in the third toilet device of the present invention, the attachment section stores the external device.

According to the first aspect, since the external device to be retrofitted is not protruded, the appearance of the remote control unit is not spoiled, and the design is improved.

According to a second aspect, in the first aspect, the external device is a heating device that blows warm air into a toilet room.

According to the second aspect, the toilet room heating function using warm air can be added later without impairing the appearance of the remote control unit. In this case, if the storage position of the heating device is set near the floor of the toilet, it is possible to effectively heat the feet where a cool feeling is easily felt. In addition, if the storage position of the heating device is set to a vicinity of a main part of the human body, it can be used not only for indoor heating of the toilet, but also for drying of a wet hand by hand washing.

According to a third aspect, in the above-mentioned second toilet apparatus of the present invention, or in the above-mentioned first and second aspects, the remote control device has a driving means for driving and controlling the external device.

In this case, if the external device is configured to output an identification signal for identifying the external device itself and the remote control device is configured to identify the external device based on the identification signal, the remote control device Can perform control suitable for the identified external device. For example, if the external device is a deodorizing device, the remote control device identifies the external device as a deodorizing device, and controls the drive of the deodorizing device to achieve deodorization. Specifically, when the user sits on the toilet seat, the deodorizing device is driven to achieve deodorization. If the external device is a muffling device for muffling during defecation, the remote control device identifies this external device as a muffling device and controls the drive of the deodorizing device to mute the sound during defecation. Specifically, when the user sits on the toilet seat, the muffler is driven to emit a dummy sound to mute the sound during defecation.

According to a fourth aspect, in the second aspect, the remote control device is installed at a location suitable for a user's operation in the remote control unit, and detects a temperature in a toilet room. There is a detecting means, and a driving means for driving and controlling the heating device according to the detected temperature.

3 is provided on the so-called sleeve,
It is stored so as not to interfere with. However, the indoor heating device 53 may be housed in the sleeve opposite to the heat exchanger unit 32.

FIG. 3 is a block diagram showing the configuration of the remote controller 200. Remote controller 20
0 has an operation button 210 and a liquid crystal display 212. The liquid crystal display 212 displays the presence or absence of automatic operation setting of the indoor heating device 53, the room temperature detected by the thermistor 232, the current time, and the like based on the control signal of the control circuit 228, as described later. The remote controller 200 further includes a battery 220 for supplying power to each component in the remote controller 200, and two light emitting diodes 22 for outputting an optical signal.
2, 224, an output circuit 226 for driving the light emitting diodes 222, 224, and a remote controller 200.
A control circuit 228 for performing overall control; a resistor R1 and a diode 230 connected in series between the battery 220 and the power input terminal of the control circuit 228; a thermistor 232 for detecting the room temperature of the toilet; Element 1
And a light receiving element 242 for receiving the light transmitted from the light emitting element 30. Power from the battery 220 is supplied to the power input terminal of the control circuit 228 via the resistor R1 and the diode 230.

The control circuit 228 has a built-in clock circuit for measuring the current time, and constantly outputs a control signal relating to the measured time to the liquid crystal display 212. As a result, the time is displayed on the liquid crystal display 212. The details of the control circuit 228 will be described later.

The output circuit 226 includes the light emitting diode 22
2, 224 for driving light. The output circuit 226 includes two transistors 244 and 245 and resistors R2 to R4. Output circuit 2
Resistors R5 and R6 are connected in parallel to the output terminal 26 (the emitter of the transistor 245), and the two light emitting diodes 222 and 22 are connected through the respective resistors.
4 are connected. Therefore, the light emitting diode 222,
224 emits an optical signal according to the signal Sp given from the control circuit 228 to the output circuit 226.

The light signal transmitted from the light emitting diodes 222 and 224 of the remote controller 200 is received by the light receiving element 120 provided in the electronic control device 100 of the sanitary washing device 10. On the other hand, an optical signal transmitted from the light emitting element 130 in the electronic control device 100 is received by the light receiving element 242 of the remote controller 200. As described above, the electronic control device 100 of the sanitary washing device 10 and the remote controller 200 perform control by performing bidirectional communication using optical signals. For example, as described later, the remote controller 200
An optical signal to start energization of the room warming fan motor 57 (see FIG. 4) is transmitted to the electronic control unit 100, and in response thereto, the electronic control unit 100 causes the room warming heater 56 and the room warming fan motor 57 (FIG. 4). When the energization is started, the electronic control unit 100 transmits to the remote controller 200 an optical signal indicating that the energization of these devices has been started. Thus, the remote controller 200 can know whether the room warming heater 56 and the room warming fan motor 57 are actually driven (energized). In this case, when adopting a configuration in which the sanitary washing device 10 itself has a switch for energizing the room warming heater 56 and the room warming fan motor 57 to perform room heating, when the switch is operated to start room heating. In addition, an optical signal indicating that power to these devices has been started is transmitted from the electronic control device 100 to the remote controller 200. Therefore, even if the room warming heater 56 and the room warming fan motor 57 are driven from a side other than the remote controller 200, the remote controller 200 can know whether these devices are actually driven. Note that a light-emitting diode, a photodiode, a phototransistor, or the like is used as the light-emitting element or the light-receiving element.

As described above, in the toilet apparatus of the present embodiment, the remote controller 200 is provided with the thermistor 232 as a temperature sensor for detecting the temperature in the tray room. The remote controller 200 is provided at a position in consideration of the convenience of the user, and is located slightly above the eyes of the user sitting on the heating toilet seat 15. For this reason, the remote controller 200 is separated from the main body 11 of the sanitary washing device 10 as well as the toilet body 5. Therefore, in the vicinity of the thermistor 232 provided in the remote controller 200, the thermistor 232 is attached to the main body 1
1, the heater 29 incorporated in the heating toilet seat 15 and the heater 29 in the heat exchanger unit 32 (FIG. 2).
There is no heat source and piping for circulation of washing water. Therefore, the thermistor 232 of the remote controller 200
Can accurately detect the toilet room temperature. Further, since the remote controller 200 is located at the above-described position, it is located at a substantially intermediate portion of the toilet space, so that the thermistor 232 is not affected by the cool air on the floor surface or the warm air on the ceiling, and reduces the average toilet room temperature. Can be detected.

As shown in the perspective view of the main part of FIG. 4, the interior heating device 53 includes a self-return type bimetal switch 54,
A hot air temperature fuse 55, a room heater 56 and a room fan motor 57 are provided. Here, the bimetal switch 54 is activated when the temperature of the hot air abnormally rises from the temperature in the normal range due to clogging of a filter (not shown) or the like, and stops energization to the room warming heater 56. When the temperature falls below a predetermined operating temperature, the room heater 56 is set to a state where it can be operated by an external control signal. The hot air temperature fuse 55 is activated by the rising heat from the room heater 56 when the blower is stopped due to a failure of the room warm fan motor 57 or the like, and stops supplying electricity to the room warm heater 56. That is, the bimetal switch 54 and the hot air temperature fuse 55
If the heater temperature rises abnormally during the control to turn on and off the heater 6 in accordance with the tray room temperature as described later, the room heater 56 is operated so as to be emergency stopped.

FIG. 5 is a block diagram showing the internal configuration of the electronic control unit 100 of the sanitary washing device 10 and its peripheral devices. The electronic control unit 100 includes a CPU 102 that executes various arithmetic processes for controlling the temperature of the cleaning water in accordance with a preset control program, a control program that is necessary for the CPU 102 to execute various arithmetic processes, and an abnormality of various components. ROM 104 in which a control program, control data, and the like necessary for inspecting the
The RAM 106 temporarily reads and writes various data necessary to execute various arithmetic processing in 2, a backup RAM 107 storing data even in a non-energized state, and a remote controller 200 received by the light receiving element 120 from the remote controller 200.

A circuit 108 and an output processing circuit 109 for outputting a signal to the room warming heater 56, the room warming fan motor 57, the light emitting element 130, and the like according to the calculation result of the CPU 102 are provided.
The backup RAM 107 is a device that can be electrically backed up by a built-in battery or a device such as a flash memory that can be electrically written and read, and various devices that do not erase data even when power is turned off can be applied.

FIG. 6 is an explanatory diagram showing various operation buttons provided on the remote controller 200 and functions of the control circuit 228. The operation buttons 210 include various buttons corresponding to various functions. That is, the operation button 2
10 includes an ass wash button 210a and a bidet wash button 2
10b, a stop button 210c, a drying button 210d for blowing out hot air, a massage setting button 210e for performing massage cleaning, a moop setting button 210f for performing move cleaning, a water discharge temperature setting button 210g for adjusting water discharge temperature, and water volume adjustment Water volume adjustment button 210h,

min and the maximum temperature Tmax), and an automatic operation setting button 210m.

The control circuit 228 has a pulse signal generator 250 in addition to the CPU and the like described above. The pulse signal generator 250 includes various operation buttons and thermistors 232.
Generates various pulse signals Sp according to the following. The pulse signal Sp is given to the output circuit 226 shown in FIG. 3, and the light emitting diodes 222 and 224 emit an optical signal according to the pulse signal Sp. The control circuit 228 is an electronic control circuit having a microprocessor and a memory, similarly to the electronic control device 100 shown in FIG. 5, and controls the control timing of the indoor heating device 53 according to a processing program stored in the memory. At the same time, various optical signals are transmitted to the electronic control unit 100 to realize the function of the pulse signal generator 250.

Here, prior to the description of the processing by the remote controller 200, a rough operation of each unit and the like will be described. When the user sits on the heating toilet seat 15 shown in FIG. 1 and operates the remote controller 200 to press, for example, the buttocks washing button 210a shown in FIG.
0 drives the driving device 41 (see FIG. 2) to advance the cleaning nozzle 40 to the cleaning position, opens the first opening / closing valve 37a of the valve unit 26, and starts jetting of the cleaning water. When the user presses the stop button 210c of the remote controller 200 to instruct the end of the cleaning after the completion of the cleaning, the first
The opening and closing valve 37a is opened to terminate the jet of the washing water, and thereafter,
The driving device 41 is reversed to retract the cleaning nozzle 40 to the storage position. When the bidet cleaning button 210b is pressed, the cleaning nozzle 40 advances to the bidet cleaning position, opens the second on-off valve 37b, starts jetting of the cleaning water, and the stop button 21
The washing is terminated by pressing 0c.

Next, the contents of the processing relating to the operation of the room heating device 53 in the toilet device of this embodiment will be described. FIG. 7 shows a control circuit 2 in the remote controller 200.
It is a flow chart which shows automatic operation judging processing performed at 28. The flowchart shown in FIG. 7 is an interrupt process that is executed every 30 seconds from the power-on and is repeatedly executed. First, the automatic operation of the indoor heating device 53 is set from the state of the operation of the automatic operation setting button 210m. It is determined whether or not it has been performed (step S10). When a negative determination is made here, this routine is temporarily terminated without performing any processing. On the other hand, when an affirmative determination is made in step S10, the current time is input from the clock circuit (step S1).
2) and input of the current room temperature Tr in the toilet room from the thermistor 232 (step S14).

After step S14, it is determined whether or not the input room temperature Tr is lower than the minimum temperature Tmin (for example, 20 ° C.) of the room temperature set by the user (step S1).
6). When an affirmative determination is made in this determination process, the precondition for indoor heating by the indoor heating device 53 is satisfied because the current room temperature Tr is lower than the minimum temperature Tmin. Therefore, in this case, the value 1 is set to the flag F1 indicating that the automatic operation of the indoor heating device 53 is performed to start the indoor heating (step S20),
This routine is ended once.

On the other hand, when a negative determination is made in the determination processing of step S16, it is determined whether the present time is daytime (step S30). The determination at this time is made based on the current time input in step S12. In this determination process, when it is affirmatively determined to be daytime, a 30-minute timer is set so that this routine is not executed for 30 minutes because the temperature in the toilet room is relatively high at present (step S32). . When the timer is set, the output of the interrupt signal for starting the process shown in FIG. 7 is stopped for the next 30 minutes, so that the process of FIG. 7 is not executed for 30 minutes. After 30 minutes have elapsed, the above-described interrupt signal is output every 30 seconds, and the processing of FIG. 7 is repeated.

If a negative determination is made in step S30 that it is not daytime, a 10-minute timer is set so that this routine is not executed for 10 minutes (step S34). The function of this 10 minute timer is the same as that of the above 30 minute timer. Note that these values of 30 minutes and 10 minutes are arbitrary, and if configured so that these values can be changed, the optimum values are set according to the installation location of the sanitary washing device 10, the degree of sunshine in the toilet, and the season. It can be set and more efficient control is executed.

If a predetermined timer is set in steps S32 and S34, the flowchart of FIG. 7 is not executed for a predetermined time after that point, as described above. Therefore, following steps S32 and S34, the value of the flag F1 is reset to 0 in order to reset the flag F1 set to 1 in the previous routine because the precondition is not satisfied in step S16. Is set (step S36),
This routine is ended once. That is, this step S3
By 6 (flag F1 = 0), the flag F1 is not kept at the value 1 for the time set by the timer.

In this case, in step 30 of the present embodiment,
Although this routine is not executed for a predetermined time only at the current time, this routine is executed based on the change of the room temperature Tr detected by the thermistor 232, specifically, the differential value or the integral value of the room temperature. May be configured not to be executed for the time. More specifically, when the change in the room temperature Tr, for example, when the differential value when the room temperature rises exceeds the first set value, it is determined that the room temperature rise is relatively slow, and the 10-minute timer is set. If the differential value exceeds a second set value that is larger than the first set value, the 30-minute timer is set on the assumption that there is a high possibility that room heating can be suppressed because the room temperature rises rapidly. If the differential value when the room temperature decreases exceeds the first set value, it is determined that the room temperature decrease is relatively slow, a 20-minute timer is set, and the differential value exceeds the second set value. In such a case, a 5-minute timer is set on the assumption that there is a high possibility that room heating is required because the temperature of the room temperature drops rapidly. In the former case (judgment based on time) adopted in the present embodiment, there is an advantage that the processing is simple and the configuration is not complicated. In the latter case (judgment based on how the room temperature changes),
There is an advantage that more accurate processing can be performed.

FIG. 8 is a flowchart showing the heating ON / OFF processing executed by the control circuit 228 in the remote controller 200. The flowchart shown in FIG. 8 is interrupted every 30 seconds and repeatedly executed until the automatic operation setting button 210m is turned on. Note that the interrupts in the flowchart shown in FIG. 7 and the flowchart shown in FIG. 8 are provided with superiority, so that there is no problem even if the respective interrupt timings overlap. When the flowchart of FIG. 8 is executed, first, it is determined whether or not the value 1 is set in the flag F1 (step S40). Since the flag F1 indicates that the automatic operation of the indoor heating device 53 is performed as described above, if the flag F1 = 0, it is not necessary to perform the automatic operation of the indoor heating device 53. . Therefore, step S
If a negative determination is made in 40, this routine is ended once without performing any processing. That is, the flag F1 is set to 0 in step S36 of the automatic driving determination process shown in FIG. 7, and a negative determination is made in step S40 for a time (10 minutes or 30 minutes) specified by the timer, and a signal to be described later is made. No processing such as transmission is performed.

On the other hand, if a positive determination is made in step S40, the current room temperature Tr is input from the thermistor 232 (step S42). Next, the read room temperature Tr
Is compared with the maximum temperature Tmax (for example, 25 ° C.) set by the user using the room temperature control button 210k.
Is lower than the maximum temperature Tmax (step S44).

Subsequent to the negative determination in step S44, it is determined whether the value 1 is set in the flag F2 (step S46). The flag F2 is set and reset in a process described later, and includes the room heater 56 and the room fan motor 57 of the room heating device 53.
Indicates that is operating. Therefore, if an affirmative determination is made in step S46 (flag F2 = 1), step S4
The negative determination in 4 indicates that the room warming heater 56 and the room warming fan motor 57 are in operation even though the room temperature Tr is higher than the maximum temperature Tmax. Therefore, following the affirmative determination in step S46, in order to stop the room warming heater 56 and the room warming fan motor 57, a signal (room warming heater OFF signal, room warming fan motor OFF signal) for stopping them is given. The data is transmitted to the electronic control device 100 on the side of the main body 11 (step S48).

In this case, on the remote controller 200 side, both of the above-mentioned OFF signals are transmitted as light signals from the light emitting diodes 222 and 224, and the electronic control unit 100
This signal is received by the light receiving element 120 (see FIG. 3). The electronic control unit 100 that has received both OFF signals stops energization of the room warming heater 56 and the room warming fan motor 57. The electronic control unit 100 controls the room heater 5
6 and a signal indicating that the power supply to these devices has been stopped (the room heater heater OF).
F completion signal, room warming fan motor OFF completion signal) is transmitted from the light emitting element 130 to the light receiving element 242 of the remote controller 200.

Note that the room warming heater OF in step S48
The transmission of the F signal and the room warming fan motor OFF signal need not always be performed at the same timing. For example, the room warming fan motor OFF signal may be transmitted after being delayed from the room warming heater OFF signal. In this manner, the electronic control unit 100 stops the energization of the room warming heater 56 in response to the previously transmitted room warming heater OFF signal, and thereafter can stop the energization of the room warming fan motor 57. Therefore, since the room heater 56, which still has residual heat even after the power supply is stopped, can be cooled by the room warm fan motor 57, it is possible to avoid the adverse effect of the residual heat of the room heater 56 on the room heating device 53 and its peripheral devices. ,preferable. When both the OFF signals are transmitted at the same time, the control program of the electronic control device 100 may slightly stop the energization of the room warming fan motor 57 more than the energization of the room heater 56. Good.

Transmission of the above-mentioned OFF signal (step S4)
Subsequent to 8), it is determined whether or not the above both OFF completion signals transmitted from the electronic control device 100 have been received by the light receiving element 242 (step S50). Here, if a negative determination is made, the present routine is ended once, and if an affirmative determination is made, a value 0 is set to the flag F2 (step S5).
2). That is, since the affirmative determination in step S50 indicates that the energization of the room warm heater 56 and the room warm fan motor 57 has been stopped, it indicates that the room warm heater 56 and the room warm fan motor 57 are operating. The flag F2 is reset to prepare for the next process. After that, the flag F
The value 0 is set to 1 (step S54), and this routine ends. That is, after the affirmative determination (flag F2 = 1) in step S46, steps S48 to S52 follow.
Since the instruction to stop energization and the energization stop of the room warming heater 56 and the room warming fan motor 57 have been executed by the above processes, the automatic operation of the room heating device 53 can be temporarily interrupted from the next time onward. Set the value 0 to F1.

On the other hand, if a negative determination is made in step S46 (flag F2 = 0), since the flag F2 = 0 has already been set in the previous routine, the automatic operation of the indoor heating device 53 is also performed in the present routine. Assuming that the operation can be temporarily stopped, the process proceeds to step S54, and the flag F1
Is set to the value 0.

Next, a case in which a positive determination is made in step S44 will be described. In this case, it is determined whether or not the value 0 is set in the flag F2 (step S5).
6). Here, if a negative determination is made, since the flag F2 = 1, the room warming heater 56 and the room warming fan motor 5 have already been set.
7 is in operation, the routine ends without performing any processing. On the other hand, if an affirmative determination is made in step S56, since the flag F2 = 0 and the room warming heater 56 and the room warming fan motor 57 are not operating, a process is performed to quickly activate them. That is, a signal for operating the room warming heater 56 and the room warming fan motor 57 (room warming heater ON signal, room warming fan motor ON signal).
Is transmitted to the electronic control device 100 on the side of the main body 11 (step S58).

Also in this case, the remote controller 200
Side, the above-mentioned both ON signals are transmitted as light signals from the light emitting diodes 222 and 224, and the electronic control unit 100
This signal is received by the light receiving element 120 (see FIG. 3). Upon receiving both ON signals, the electronic control unit 100 starts energizing the room warming heater 56 and the room warming fan motor 57. The electronic control unit 100 controls the room heater 56
After the power supply to the room warming fan motor 57 is started, a signal (room warming heater ON completion signal, room warming fan motor ON completion signal) indicating that power to these devices is started is transmitted from the light emitting element 130 to the remote controller 200. Light receiving element 24
Send to 2.

Transmission of the above ON signal (step S5)
Subsequent to 8), it is determined whether or not the both ON completion signals transmitted from the electronic control device 100 have been received by the light receiving element 242 (step S60). Here, if a negative determination is made, this routine is immediately terminated, and if an affirmative determination is made, the value 1 is set to the flag F2 (step S6).
2) This routine ends. That is, step S60
Since the affirmative determination in step 4 indicates that the energization of the room warm heater 56 and the room warm fan motor 57 has been started, the flag F2 indicating that the room warm heater 56 and the room warm fan motor 57 are operating is set. And prepare for the next process.

Accordingly, the room temperature T input in step S42
If r is lower than the maximum temperature Tmax, the process from step S56 to step S62 is performed upon receiving an affirmative determination in step S44. Thereby, warm air is blown into the toilet room by the room warming heater 56 and the room warming fan motor 57, and heating is performed. Then, until a negative determination is made in step S44 of this routine after the next time,
This heating is continued. However, if a negative determination is made in step S44, it is determined that the room temperature Tr is higher than the maximum temperature Tmax and heating is not required, and steps S46 to S5 are performed.
By the processes up to 4, the energization of the room warming heater 56 and the room warming fan motor 57 is stopped.

In addition, in the remote controller 200, the room temperature T input in steps S14 and S42 is set.
r, the minimum temperature Tmin and the maximum temperature Tmax adjusted by the room temperature adjustment button 210k are displayed on the liquid crystal display 212. To explain the situation, as shown in FIG. 9, the minimum temperature Tmin and the maximum temperature Tmax are indicated by numerical values on the horizontal axis having a temperature scale, and the room temperature Tr is indicated by symbols indicated by black triangles. You. The symbol indicating the room temperature Tr is displayed by moving along the horizontal axis, as shown by the detected room temperature at that time. Such a display need not always be performed, and may be performed during a predetermined time when the room temperature control button 210k is operated.

As described above, in the toilet apparatus of the present embodiment, the following effects can be obtained by the above-described automatic operation determination processing and heating ON / OFF processing performed on the remote controller 200 side.

When the power is turned on and the automatic operation setting button 210m is turned on by the user, the current time and room temperature are input, and the current room temperature is set to the minimum temperature Tmin (for example, 20 ° C.) set by the user. ), It is assumed that the room heating device 53 is to be automatically operated to start room heating (flag F1 = 1 / step S2).
0). In this situation, the power supply to the room warming heater 56 and the room warming fan motor 57 is controlled so that the room temperature Tr does not exceed the maximum temperature Tmax (for example, 25 ° C.) set by the user (steps S44 to S62). ), The heating of the toilet room is automatically continued. Therefore, the toilet can be used comfortably even when it is cold in winter. Moreover, since the measurement of the room temperature Tr necessary for heating as described above is performed by the thermistor 232 provided in the remote controller 200 as shown in FIG. 3, an accurate and average room temperature can be detected. As a result, on / off control of the room warming heater 56 and the room warming fan motor 57 is performed based on the accurate and average detected room temperature (steps S444 and S4).
8, step S58), it is possible to comfortably heat the toilet room without giving the user a feeling of strangeness. Moreover,
A member only for installing the sensor is not necessary, and a power supply for temperature detection by the thermistor 232 can be used in combination with the remote controller 200. Therefore, there is no need to install a power supply only for temperature detection and a wire facility. There is no problem.

When starting or stopping the heating by the room warming heater 56 and the room warming fan motor 57, the timing is controlled by the remote controller 200.
(Step S48, Step S58). Then, the electronic control device 1 that controls the entire sanitary washing device 10
On the side of 00, only the start and stop of energization to the room warming heater 56 and the room warming fan motor 57 are performed at the timing determined by the remote controller 200.
For this reason, the calculation load on the electronic control unit 100 that controls various devices such as the drive unit 41 in the hot water / nozzle control unit 14 can be reduced. Specifically, the electronic control device 100 does not need to perform the processes shown in FIGS. 7 and 8. Further, the room warm heater 56 and the room warm fan motor 5
7, the control of the electronic control unit 100 can be simplified. As a result, the electronic control unit 100
Does not hinder the various processes for the local cleaning originally performed.

Further, as shown in the flowchart of FIG. 7, if the room temperature Tr is equal to or higher than the minimum temperature Tmin (20 ° C.) when the automatic operation setting button 210m is in the on state, the subsequent processing is performed as shown in FIG. The illustrated automatic driving determination process itself is not executed for a predetermined time. More specifically, the automatic driving determination process shown in FIG. 7 is not performed for 30 minutes during the daytime when the temperature is expected to change in the rising direction and for 10 minutes thereafter during the night when the temperature is expected to change in the decreasing direction. To do. Therefore, the number of executions of the automatic operation determination processing is reduced, and the processing load on the remote controller 200 is reduced. Note that other processing can be executed quickly. Moreover,
As described above, the flag F1 is set to 0 over the non-execution period of the automatic driving determination process. During this period, only step S40 is executed in the flowchart of FIG. For this reason, since steps S48 and S58 in the flowchart of FIG. 8 are not executed during the non-execution time, the remote controller 200
No optical signal is transmitted from the side. As a result, it is possible to suppress the consumption of electric energy required for transmitting the optical signal, and to thereby prolong the life of the battery 220.

Further, when heating is interrupted due to a negative determination in step S44 (the room temperature Tr is equal to or higher than the maximum temperature Tmax), depending on the state of the flag F2 at that time, the room warm heater 56 and the room warm fan motor 57 have already been activated. If not in operation (flag F2 = 0), step S48 is not executed. In addition, even when heating is performed in accordance with the affirmative determination in step S44, if the room warm heater 56 and the room warm fan motor 57 are already operating (flag F2 = 1) depending on the state of the flag F2, step S58 is performed. Do not execute. That is, the off signal is not repeatedly transmitted to the non-operating devices (the room heater 56 and the room warmer fan motor 57), and the on signal is not repeatedly transmitted to the operating devices. Therefore, the number of transmissions of the optical signal from the remote controller 200 side can be reduced, and the consumption of electric energy required for the transmission of the optical signal can be further suppressed.
The life of the battery 220 can be further extended.

As shown in FIG. 9, the room temperature Tr, the minimum temperature Tmin, and the maximum temperature Tmax are displayed on the liquid crystal display 212 so that the relationship between these temperatures can be visually recognized. Specifically, the current room temperature Tr is the minimum temperature T
Whether it is near min or near the maximum temperature Tmax can be read at the position of the symbol representing the room temperature Tr. For this reason, the user who feels that heating is insufficient can easily adjust the minimum temperature Tmin and the maximum temperature Tmax to a higher value with the room temperature adjustment button 210k. A user who feels overheated can easily adjust these temperatures lower. Then, through this adjustment, the ON / OFF timing of the heating by the room warming heater 56 and the room warming fan motor 57 can be changed, so that the user can be quickly heated to a desired temperature.

Next, a modification of the above toilet apparatus will be described. The first modified example is a modification of Step S5 in FIG.
0, the following processing is performed when a negative determination is made in step S60. That is, as shown in FIG.
Following the negative determination in step S50, the above both OFFs
The value of the counter COFF for counting the number of times the completion signal has not been received is incremented by 1 (step S1).
00), the value of the counter COFF is equal to a predetermined counter value C
1 (for example, 5) (Step S1)
05). If a negative determination is made here, the number of misses in receiving the OFF completion signal has not reached the predetermined number, and this routine ends. On the other hand, if an affirmative determination is made, it is displayed on the liquid crystal display 212 that a communication failure has occurred due to some cause, for example, adhesion of dust or the like to the transmission / reception unit (step S110), and the user is alerted. . Thereafter, the process of the flowchart of FIG. 8 in this state is performed only in step S40, and the value of the flag F1 is set to 0 in order to refrain from transmitting unnecessary optical signals as described above.
Is set and the value of the counter COFF is reset (step S120). Both of the above ON in step S60
The same applies to the case where the completion signal cannot be received. In this case, instead of the counter COFF, a counter CON that counts the number of times that both ON completion signals cannot be received is used.

According to the first modification, since an optical signal is not transmitted while a communication failure has occurred, the life of the battery 220 can be extended by suppressing power consumption. Also, by indicating that a communication failure has occurred,
The user can be alerted to promptly resolve this communication failure.

Next, a second modification will be described. The second modification is configured to perform the following processing when an affirmative determination is made in step S56 in FIG. That is, as shown in FIG. 11, following the affirmative determination in step S56, a temperature difference ΔT between the maximum temperature Tmax and the room temperature Tr input in step S42 is calculated (step S13).
0). Thereafter, based on the calculated temperature difference ΔT, the amount of current Hw to be supplied to the room heater 56 is calculated (step S14).
0). More specifically, when the temperature difference ΔT is large, a sense of heating cannot be obtained unless heating is performed quickly. Therefore, the amount of current Hw is calculated such that the greater the temperature difference ΔT, the greater the amount of current Hw. in this case,
The power supply amount Hw can be a power supply amount per unit time. Subsequent to step S140, in addition to the room warming heater ON signal and the room warming fan motor ON signal for operating the room warming heater 56 and the room warming fan motor 57, a signal representing the above-described current amount Hw (current amount) Hw signal)
Is transmitted to the electronic control device 100 on the side of the main body 11 (step S150), and thereafter, step S60 is performed.
Move to In this case, the electronic control unit 100 that receives the signal starts the energization of the room warming heater 56 and the room warming fan motor 57 as described above, and uses a device such as a variable resistor to heat the room warming heater. The amount of current applied to the electrode 56 is controlled so as to be the above-described amount of current Hw.

According to the second modification, step S4
In performing the heating in response to the affirmative determination in step 4, a temperature difference ΔT between the maximum temperature Tmax, which is the target temperature, and the room temperature Tr is obtained. The larger the temperature difference ΔT is, the larger the amount of electricity supplied to the room warming heater 56 is, and the quicker heating can be performed. Also, if the temperature difference ΔT is small, the amount of electricity can be reduced to perform gentle heating. Then, the amount of power to the room heater 56 that determines such a heating mode is determined by the remote controller 200, and a signal indicating the determined amount of power is transmitted to the electronic control unit 100. . For this reason, the electronic control unit 100 that controls the entire sanitary washing device 10 simply supplies power to the room warming heater 56 based on the power supply timing determined by the remote controller 200 and the power supply amount. Therefore, even in the second modification, the electronic control unit 10
0 can reduce the calculation load, and the electronic control unit 1
The control at 00 can be simplified.

Next, a toilet apparatus according to a second embodiment will be described. In the following description, the first
The members and components that perform the same functions as in the first embodiment are denoted by the same reference numerals used in the first embodiment, and detailed descriptions thereof are omitted. FIG. 12 shows an overall view of the toilet apparatus of the second embodiment, and is an external view showing a Western-style toilet together with a sanitary washing device 300. FIG. 13 is a block diagram showing the configuration. The sanitary washing device 300 is provided with a configuration only for performing a cleaning function for local cleaning, and does not include members for performing other functions such as indoor heating, deodorization, and noise reduction other than the cleaning function. In the second embodiment, a remote control unit 320 having a remote controller 310 is provided.

The remote controller 310, like the remote controller 200 in the first embodiment, is configured to transmit an operation command relating to local cleaning to the sanitary washing device 300, for example, a bottom cleaning command, a stop command, and the like.
An operation button 210 for that purpose, a light emitting element 312 for transmitting each of these signals as an optical signal, a liquid crystal display 2
12 (see FIG. 13). Also, the remote controller 310 is provided at a position in consideration of the convenience of the user, and is located slightly above the eyes of the user sitting on the heating toilet seat 15. For this reason, the remote controller 200 includes the sanitary washing device 10 as well as the toilet body 5.
Is away from the main body 11. Since the remote controller 310 has the thermistor 232, the temperature of the toilet room can be accurately and averagely detected by the thermistor 232. Further, the remote controller 310 has a control circuit 314 configured as a logical operation circuit similarly to the control circuit 228 in the remote controller 200, and the control circuit 314 generates and transmits the above optical signal. The remote controller 310 uses a commercial power supply.

The remote control unit 320 is buried and installed on the toilet wall so that its front surface is substantially the same as the toilet wall. As shown in FIG. 14 which is a schematic diagram schematically showing the remote control unit 320, the present embodiment has four device storage blocks 321 to 324. As shown in the figure, the uppermost equipment storage block 3
A remote controller 310 is built in and fixed to 21. A toilet paper holder 326 is incorporated and fixed in the second-stage device storage block 322. The third-stage device storage block 323 is not used in the present embodiment, but is used when a later external device such as a deodorizing device or a sound deadening device is installed. A heating unit 330 having an indoor heating device 53 is incorporated and fixed to the lowermost equipment storage block 324. A lid 325 is attached to an unused block such as the device storage block 323.

Next, the electrical relationship between the devices stored in each storage block in the remote control unit 320 will be described with reference to FIGS. As schematically shown in FIG. 14, a bus line 340 connected to a control circuit 314 of the remote controller 310 is provided in advance on the back of the remote operation unit 320. The remote controller 31 is connected to the bus line 340.
A bus line is connected to each device storage block, which is to store an external device that needs to transmit and receive signals to and from the device. In this embodiment, the device storage block 32
3,324 are planned to be used in this manner, so that the bus lines 342 and 344 are connected to the bus line 340 and distributed to the inside of each storage block before the remote operation unit 320 is buried in the wall. Has been established. If the device storage block 322 is also planned, it goes without saying that a bus line is also provided in this block.

The bus lines 342 and 344 extending to the inside of the device storage block have unit connection ports 343 and 345 for connecting external devices. Each of the unit connection ports 343 and 345 has a connector (not shown) for connecting an external device stored in the corresponding device storage block. Therefore, when the heating unit 330 is retrofitted after the remote operation unit 320 is installed, the bus line 332 of the heating unit 330 is electrically connected to the bus line 344 and the control circuit 314 via this connector. In this case, together with the connection of the bus line of the heating unit 330 to the unit connection port 345, the heating unit 330 is connected to a commercial power supply via a remote controller 310 by a power supply line (not shown). For this reason, the heating unit 330 attached to the remote operation unit 320 is placed under the control of the control circuit 314 in the remote controller 310 and receives power from a commercial power supply. The heating unit 330 has a data transmission / reception unit 334 which is a logical operation circuit for transmitting / receiving data to / from the remote controller 310. Equipment storage block 32 not used at present
The same applies to the case where an external unit such as a deodorizing device and a sound deadening device is retrofitted to 3.

Next, a description will be given of electrical processing and control after the external equipment such as the heating unit 330 is attached.

Each external unit to be retrofitted, for example, the heating unit 330, stores its own identification code (ID) in a memory (not shown) provided in the data transmitting / receiving section 334.
Numbers). On the other hand, the remote controller 3
Reference numeral 10 stores an identification code (ID number) for each external unit that can be retrofitted in advance in a memory (not shown) provided in the control circuit 314. Then, when heating unit 330 is electrically connected to remote controller 310 as described above, control circuit 314 instructs data transmission / reception unit 334 of heating unit 330 to transmit an identification code. When the identification code is transmitted to the control circuit 314 in this way, the control circuit 314 checks the stored identification code against the transmitted identification code,
It is identified that the retrofitted external unit is the heating unit 330. The same applies to the case where a deodorizing device or a silencing device is retrofitted.

In this way, the control circuit 314
After identifying the 30, the control circuit 314 reads a program necessary for controlling the heating unit 330 from its own memory and executes the program. More specifically, the control circuit 314 reads a program for the automatic operation determination process shown in FIG. 7 and a program for the heating on / off process shown in FIG.

That is, similarly to the first embodiment, the remote controller 310 performs a process of determining a state in which the heating unit 330 is automatically operated (see FIG. 7). Further, as shown in the flowchart of FIG. 15, the timing of turning on / off the room heating device 53 on the remote controller 310 side is determined, and an ON signal or OF signal is output.
The F signal is transmitted to the heating unit 330. 15, the flowchart of FIG. 15 differs from the flowchart of FIG. 8 in that the signal transmission in steps S48 and S58 is performed directly between the two devices using the bus line. It differs from the flowchart of FIG. 8 only in that the processing is omitted. In the second embodiment, since transmission and reception of signals between the remote controller 310 and the heating unit 330 are performed using a bus line, it can be said that there is no hindrance to data transmission and reception. No processing is required.

In this case, the program for executing the above-described flowchart includes the control circuit 31 as described above.
4 is read out after the heating unit 330 is connected and the control circuit 314 recognizes the identification code thereof, and is subsequently executed.

As described above, in the toilet apparatus of the second embodiment, a heating unit 330, a deodorizing device, a sound deadening device and the like can be retrofitted to a remote control unit 320 having a remote controller 310 and installed on the toilet wall. It has storage blocks 323 and 324. For this reason, restrictions on the installation space in the toilet room and the sanitary washing device 3
00 without interference with the heating unit 330,
Various external devices, such as a deodorizing device and a silencing device, can be easily retrofitted.

Further, even if the above various external devices, for example, the heating unit 330 are retrofitted,
0 is stored in the device storage block 324 and does not protrude from the front surface of the remote operation unit 320. Therefore, even if the heating unit 330 and the like are retrofitted,
20 can be improved in design without impairing its appearance. Moreover, in the present embodiment, the heating unit 3
30 has been retrofitted, so that the heating function that was not provided in the
20 can be added later without impairing the appearance.
Then, the heating unit 330 is connected to the remote control unit 320.
Because it is housed at the bottom of the floor and located near the floor of the toilet, it is possible to effectively heat the feet where cold feeling is easily felt. Note that the heating unit 330 is connected to the uppermost equipment storage block 3.
22, the heating unit 330 is located near a main part of the human body.
It can also be used for drying hands that are wet by hand washing.

Further, in the second embodiment, a control program for controlling the retrofitted heating unit 330 is stored in the memory of the control circuit 314 in the remote controller 310. The control is performed by the control circuit 314. For this reason, it is possible to centrally control the driving of the retrofitted heating unit 330 together with the sanitary washing device 300 from the beginning by the remote controller 310, and it is possible to enhance the usability when driving the heating unit 330.

Further, the room temperature Tr used as a control parameter when controlling the heating unit 330 is detected by the thermistor 232 provided in the remote controller 310. Therefore, similarly to the above-described first embodiment, it is possible to drive and control the heating unit 330 based on the average and accurate detected room temperature, so that the toilet room can be heated without giving a user an uncomfortable feeling.

The embodiments of the present invention have been described above.
The present invention is not limited to the above-described examples and embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.
