Abstract

PURPOSE:To surely hold a state of a lavatory seat in a state before executing electric re- conduction, when an electric conduction state is disconnected, and electric re-conduction is executed by always outputting an ON signal for warming the lavatory seat from an output terminal of a controller, and attaching a lavatory seat switch for turning on/off an electric conduction circuit between the output terminal and the electric conduction circuit for executing an electric conduction to a heater of the lavatory seat. CONSTITUTION:In the case a service interruption accident is generated in the cource of electric conduction to a lavatory seat 3, an electric conduction to a heater 14 is stopped. When the service interruption is recovered, in the case a temperature of the lavatory seat 3 is below a set temperature, since a control program is integrated into a microcomputer so that an ON signal is outputted from its output terminal, an electric conduction is executed immediately to the heater 14, and the lavatory seat 3 is warmed. In this case, as for a lavatory seat switch 27, a switch of a mechanical type which is not obstructed by a command of the microcomputer is used, therefore, even if data of the microcomputer is initialized by an electric re-conduction, it does not occur that an electric conduction to the heater 14 of the lavatory seat 3 is obstructed. Also, since the lavatory seat switch 27 of a mechanical type is inserted and connected, when the lavatory seat switch 27 is in an OFF state, it does not occur that the lavatory seat 3 is warmed after the service interruption is recovered.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention sprays hot water onto the private parts of the user after using the toilet to clean the private parts, and after cleaning, hot air is jetted to wash the private parts of the user. The present invention relates to a control device for a sanitary cleaning device that allows for sanitary treatment of private parts after using the toilet without bothering them.

[Conventional technology]

In recent years, toilets have been equipped with a cleaning means that heats hot water to an appropriate temperature and squirts it out at the back of the top of the toilet bowl, a drying means that dries the private parts with warm air after washing, and a toilet where the user is seated. A sanitary cleaning device equipped with a toilet seat warming means that maintains the temperature of the toilet seat at an appropriate temperature is installed so that after using the toilet, private parts can be washed and dried hygienically without using hands.

The cleaning means of the device may include, for example, a solenoid valve and a temperature sensor that detects the water temperature built in between the water supply source and a nozzle for jetting cleaning water that is movable toward the inside of the toilet bowl. Connect the heater to the heating device with a water supply pipe, connect the heater attached to the heating device to the power supply via a switching element, and instantly heat the cleaning water flowing into the heating device to the set temperature (approximately 38℃). At the same time, based on the difference between the detection signal detected by the temperature sensor of the heated cleaning water and a reference signal indicating the set temperature, energization of the switching element is controlled to keep the temperature of the cleaning water jetted from the nozzle constant. There are instant heating methods.

Next, as a drying means, we cleaned the outlet of a hot air blower equipped with an electrically driven fan, a heater that heats the blown air generated by the fan, and a temperature sensor that detects the temperature of the heated air (warm air). A detection signal obtained by detecting the temperature of hot air ejected from the outlet by a temperature sensor, which is placed near the water ejecting nozzle, connects an electric motor to a power source, and connects a heater via a switching element, and a reference Temperature (about 50℃)
The device is configured to control the energization of the heater and blow out warm air by comparing it with a reference signal indicating the temperature.

Furthermore, when adjusting the temperature of the toilet seat, a heater attached to the inner surface of the toilet seat is connected to the power source via a switching element.
The energization of the heater is detected by comparing the detection signal of a temperature sensor installed inside the toilet seat with a reference signal indicating the standard temperature of the toilet seat (approximately 35°C).

The standard set temperature of the hot air and toilet seat, including the temperature of the washing water, can be variably controlled by a microcomputer (hereinafter referred to as microcomputer), allowing the user to set the temperature to their own preference. .

[Problems to be solved by the invention]

In the conventional sanitary washing equipment described above, the temperature control of washing water, etc. is now performed by a microcomputer, and the temperature control by this microcomputer requires fewer parts than the conventional control parts such as comparators. Because the number of points and installation space are reduced, and temperature control itself can be automated,
It's very convenient.

However, if all the temperature controls for the washing water and the like are microcomputerized, although there are advantages as described above, there are also the following problems. In other words, if the sanitary cleaning equipment is unplugged, and the power is turned on again after a power outage (including momentary power outage), all of the internal memory of the microcontroller will be initialized, causing a power outage. The memory contents of the state used before this happens will be erased. In this case, the set temperature of the cleaning means and drying means simply returns to the initial setting value, so the user can continue cleaning and drying their private parts as before by operating the operation switch as necessary. In addition, the set temperature can be reset according to preference, so there is no particular inconvenience when using it. However, when the toilet seat is kept warm, the temperature setting is the same as when setting the temperature of the flushing water, but there was a problem with the previous method of energizing the toilet seat.

In other words, since the power supply to the toilet seat is controlled by a microcomputer that controls the seat temperature, the output end of the microcomputer always receives an ON signal,
Alternatively, the mode is set so that only one of the OFF signals is output. For this reason, for example,
If the microcomputer's program sequence is set to ON mode so that it always outputs an output signal that is in the ON state, the toilet seat switch that outputs the energization command to the toilet seat heater to the microcomputer is always initially in the ON state according to the microcomputer's program sequence. Therefore, when the sanitary washing device is energized, the toilet seat switch is turned on, and an ON signal is output from the output terminal of the microcomputer to conduct the switching element and close the toilet seat. If you want to energize the heater and then cut off the energization to the heater, press the toilet seat switch to cut off the energization command to the microcomputer, stop the microcomputer's program to energize the toilet seat heater, and turn off the power to the heater. Prevents energization. To re-energize the toilet seat heater in this state, press the toilet seat switch again and the heater will be re-energized according to the program sequence of the microcomputer.

However, if a power outage occurs after the user presses the toilet seat switch to cut off power to the heater, and the power is restored, the program sequence of the microcomputer will cause the toilet seat switch to turn off without turning on the toilet seat switch. An energization command is output. As a result, the output terminal of the microcontroller is always O.
Since the N mode is set, the toilet seat heater will be automatically energized when the power is restored. In this case, if the user is aware of the power outage accident, there is not much of a problem, but if the user is not aware of the power outage, why is the toilet seat being energized and becoming warm even though the power to the toilet seat has been turned off? I'm worried that there will be someone there. In other words, while the microcomputer's program sequence is energizing, the toilet seat is always energized.
When the mode is set, regardless of the user's intention, after the power is reenergized, the state is set to the opposite state from the state before the power outage, which causes the user to feel uneasy.

Therefore, contrary to the above, the program sequence of the microcomputer is turned off so that it always outputs an output signal that is in the OFF state.
If the mode is set, the toilet seat heater will always be in the OFF state when energizing starts, so the user must press the toilet seat switch to change it to the ON state and then energize it.

In addition, in this method, unless the power is turned off by the user's will while the toilet seat is being energized, when the power is re-energized after a power outage accident, the energization to the toilet seat will start off. When energizing the toilet seat, it is troublesome to have to press the toilet seat switch each time to start energizing the toilet seat. Further, even if an accident such as a momentary power outage occurs while the power is being supplied to the toilet seat, the power supply to the toilet seat will start OFF after the power is restored, as described above. For this reason, even though the user did not press the toilet seat switch to cut off the power while the toilet seat was energized, the power was changed to OFF start after the power was restored, so the toilet seat may have malfunctioned. There was a risk that this would lead to anxiety and distrust.

To solve the above problem, for example, you can use non-volatile memory such as EEFROM for the microcomputer's storage device (RAM), or prepare the microcomputer itself with a backup power source in case of a power outage. can be solved. However, if you use non-volatile memory for RAM, the microcontroller itself needs 1ti! It is necessary to significantly change the internal circuit configuration for the first circuit, and even if a backup power supply is provided, an extra space factor is required, and the timing of charging the power supply must be managed. However, there are various problems, and in addition, the number of parts increases, which increases the manufacturing cost of the sanitary cleaning device.

The present invention solves the above-mentioned problems, and when the power is turned on to the toilet seat or when the power is turned off, there is a power outage accident, or when the plug of the device is disconnected from the power source and the power is cut off, the power is turned on again. It is an object of the present invention to provide a microcomputer-controllable sanitary washing device in which the state of energization or non-energization of the toilet seat is reliably maintained in the state before re-energization.

[Means and Effects for Solving the Problems] The present invention provides a microcomputer that sends an output signal to a temperature control circuit of a toilet seat, and provides an ON function that always maintains the output signal in an ON state.
An alternate-type toilet seat switch with a locking mechanism next to it is connected between the output terminal of the microcomputer that outputs an energization command signal to the toilet seat and the temperature control circuit of the toilet seat. When energizing,
Since the output end of the microcomputer is set to ON mode, when the toilet seat switch is turned ON,
An ON signal is output from the microcomputer to the toilet seat temperature control circuit, which starts energizing the toilet seat heater. If a power outage occurs in this state, the energization will be stopped, but if the power is restored, the toilet seat switch will be activated artificially. Unless it is switched to the OFF state, the ON state is maintained, so power supply to the toilet seat heater is automatically restarted. Also, turn off the toilet seat switch voluntarily.
A power outage occurs while power is turned off to the toilet seat heater, and when the power is restored, even if an ON signal is output from the output terminal of the microcomputer, the toilet seat switch will remain in the OFF state unless it is intentionally turned ON. Therefore, the toilet seat is not energized.In other words, in the present invention, when the toilet seat temperature is controlled by a microcomputer, even if a power outage occurs, the toilet seat will not be energized after the power outage is restored unless the toilet seat switch is activated. Since the status is always maintained in the state before the power outage, there is no possibility that the energization status of the toilet seat is changed due to a power outage that occurs without the user's knowledge. To provide a sanitary cleaning device that eliminates user's anxiety and mistrust by having a simple configuration that includes a normal alternate type toilet seat switch that does not turn ON or 0FFL with a signal from a microcomputer. It is characterized by

At this stage, the operating switch for "washing" or "drying"
Microcomputer 1 unless you operate (turn on) St, ss.
8 does not operate, and the heaters 7 and 10 inserted and connected to the energizing circuits of the heating device 9 and the drying device 13 are not energized. On the other hand, in the toilet seat 3 as well, unless the toilet seat switch 27 is turned on, the heater 14 provided in the energizing circuit of the toilet seat 3 will not be energized. In this case, if the temperature of the toilet seat 3 is below the set temperature, An ON signal for energizing the heater 14 is always output from the output terminal B of the microcomputer 18. In the above state, when the toilet seat switch 27 is turned on, the output terminal 8. of the microcomputer 18 is turned on. The photodiode D of the phototriac coupler PTCs lights up in response to the ON signal output from the phototriac coupler PTCs, turning on the phototriac PTCs. Therefore, a gate current flows through the gate of the switching element Th, making the switching element Ths conductive, energizing the heater 14, and warming the toilet seat 3.

When the temperature of the toilet seat 3 reaches the insulating temperature (approximately 35° C.) by energizing the heater 14, the temperature sensor 15 detects this, and the sensor output circuit 20 sends the detection signal C to the microcomputer 1.
It is input to the input terminal A of 8. The microcomputer 18 takes in the detection signal C, compares it with a set value, and if it is greater than or equal to the set value, the CPU outputs a signal # to stop energizing the heater 14.
It passes through ABs and is output to the phototriac coupler PTCs, which is turned off. Therefore, the power supply to the heater 14 of the toilet seat 3 is cut off, and the heating of the toilet seat 3 is stopped. When the temperature of the toilet seat 3 falls below the set temperature due to the power supply to the heater 14 being stopped, the temperature sensor 15 detects this and sends it to the microcomputer 18 manually. The microcomputer 18 compares it with the set value, and based on the difference, an energization command signal is output from the output terminal B, turns the phototriac PTC ON, and energizes the heater 14 again to heat the toilet seat 3. By repeating the above actions, the stool! 3 can always maintain the set temperature.

As mentioned above, if a power outage accident occurs while the toilet seat 3 is being energized, the energization to the heater 14 is stopped.

Then, when the power outage is restored, if the temperature of the toilet seat 3 is below the set temperature, the microcomputer 18 has a control program built in so that an ON signal is output from its output IBS, so the heater 14 is immediately energized. The toilet seat 3 can be kept warm. In this case, the toilet seat switch 27 uses a mechanical switch that is not affected by commands from the microcomputer 18, so even if the data in the microcomputer 18 is initialized by reenergizing after a power outage, the heater for the toilet seat 3 14
This means that, in particular,
If there is a power outage while the toilet seat switch 27 is OFF,
After the power is restored, if the switch is operated by conventional microcomputer control, the program is set so that the microcomputer is initialized and an ON signal is always output from the output terminal of the microcomputer, and the toilet seat switch is turned off. Even if the toilet has been switched to ON after the power is restored, the toilet seat will be warmed and ON (i) will be output, creating a sense of distrust among the users.

However, in the present invention, a mechanical toilet seat switch 27 is inserted and connected between the output end B of the microcomputer 18 and the current-carrying circuit of the toilet seat 3, so if the toilet seat switch 27 is in the OFF state, the microcomputer Even if an ON signal is output from the output terminal B of 18, this signal is not sent to the phototriac coupler PTC3. Therefore, the stool WL3 is never heated when the power is restored.

That is, in the present invention, even after the power is restored, the toilet seat 3 is maintained in the power outage state, so the user does not feel anxious or distrustful at all.

Furthermore, when resuming power supply to the toilet seat 3, since the user turned the toilet seat switch 27 to the OFF state at his/her own discretion, the user must turn on the toilet seat switch 27 to voluntarily energize the toilet seat 3 prior to power supply. It is impossible to feel the inconvenience of doing so.

Next, a case will be described in which the sanitary cleaning device of the present invention is used to clean and dry private parts after using the toilet.

First, if you want to clean your private parts, select "Cleanse" in the operation circuit 19.
Press the operation switch S2. Then, the input terminal A2 of the microcomputer 18 is connected to the constant voltage power supply Vcc, and the microcomputer 18 is connected to the constant voltage power supply Vcc.
A signal for canceling the stopped state of the heating device 9 in the heating device 8 is input. Therefore, from the output end B of the microcomputer 18 to the solenoid valve 5
An output signal for opening is output to the solenoid valve control circuit 22,
Transistor Q is turned on to energize relay X, and its interchamber contact Xa is closed, thereby closing the energizing circuit of solenoid valve 5. Therefore, the electromagnetic valve 5 is opened by energization, and tap water flows into the heating device e9. On the other hand, a signal for turning on the heater 7 is also output from the output terminal B3 of the microcomputer 18 in response to the input of the stop release signal for the heating device 9. In this case, if the temperature of the tap water has reached the standard temperature (approximately 38"C), the ON signal will not be output. Normally, the temperature is below the standard temperature, so the temperature sensor 8 installed in the heating device 9 detects the temperature of the tap water. When the temperature is detected and the detected temperature a is input to the microcomputer 18, the microcomputer 18 takes in the detection signal a, compares it with a set value, and outputs an output signal that determines the phase of energizing the heater 7 based on the difference, that is, The ON signal is output from the output @Bs.The phototriac coupler PTCI is turned ON by the signal output from the output terminal B of the microcomputer 1B.
I,, thereby making the switching element Th conductive and starting energizing the heater 7. As a result, the tap water is heated almost instantaneously to the reference temperature while passing through the heating device 9, and is sprayed from the nozzle 6 toward the local area. In addition,
When the temperature of the heated cleaning water reaches the reference temperature, the temperature sensor 8 detects this and a detection signal a is inputted to the microcomputer 18. If it matches the set value of the microcomputer 18, the output terminal B of the microcomputer 18, A signal to stop the power supply to the heater 7 is output to the phototriac PTC, which is then turned off.
On the other hand, if the temperature of the cleaning water falls below the reference temperature, the temperature sensor 8
detects this and outputs a signal to re-energize the heater 7 from the microcomputer 18, and restarts energizing the heater 7. When cleaning is finished, press the "stop" operation switch S1, and a signal to stop the heating device 9 will be input to the input terminal A□ of the microcomputer 18, and the heater 7 will be turned off from the output terminal B of the microcomputer 18. Stops the output of the signal that commands energization. Further, the output of the signal commanding the energization to the solenoid valve 5 is stopped from the output terminal B of the microcomputer 18, and the solenoid valve 5 is closed to stop the tap water from flowing into the heating device 9, and the tap water is stopped. The jetting from the nozzle 6 is stopped.

After completing the private part washing with washing water as described above, press the "drying" operation switch. Then, as in the case of washing, a signal to release the stopped state of the drying device 13 is sent to the input terminal of the microcomputer 18. Accordingly, the blower 12 is connected to the blower control circuit 23 from the output terminals Ba and Ba.
The output signal that rotates the temperature Wi? 11 circuit 2
The phototriac PTC, No. 4, is synchronized with the power supply by the zero cross control circuit 25 so that the power supply voltage reaches the zero point (
Ov), an output signal is output that instructs the heater 10 to be energized by being turned on. Therefore, the relay Y is energized and closes its normally open contact Ya, closing the energizing circuit of the blower 12 to drive the blower 12, and also turning the phototriac coupler PTC, ONI, by the signal from the output terminal B4. , the heater 10 is energized by the conduction of the switching element Thg, the air discharged from the blower 12 is heated and heated, and the air is injected from the outlet 10a of the blower 12 toward the private parts to clean the private parts that have been cleaned. Dry.

The temperature of the hot air is detected by a temperature sensor, and the reference temperature (approximately 5
0° C.), the heater 10 is de-energized by a command from the microcomputer 18.

To finish the drying, press the "stop" operation switch to stop the blower 12 and cut off the power to the heater 11, as in the case of cleaning, to finish the local drying process.

[Effects of the Invention] As explained above, the present invention provides a sanitary cleaning device in which each temperature of the wash water and the warm air toilet seat can be automatically set according to the user's preference by a control device equipped with a microcomputer. The output terminal of the device that sends the command to energize the toilet seat can always output an ON signal to maintain the toilet seat at a temperature that is kept warm, and the output terminal and the energization circuit that energizes the heater of the toilet seat are connected. In between, a toilet seat switch was installed to turn the energizing circuit on and off without being interfered with by the output signal from the control device, thereby constructing a sanitary washing device.
While the toilet seat is energized, when the power is once turned off due to a power outage and then re-energized, the toilet seat will maintain the state before the power outage unless the user operates the toilet seat switch, and the toilet seat switch will be turned OFF before the power outage. If left unattended, it will remain in the same state even after the power outage is restored, which results in a strange situation where the status of the toilet seat changes between before and after the power outage due to microcomputer control, as in the past. This makes it possible to eliminate such phenomena, and to provide a sanitary cleaning device that does not cause users to feel anxious or distrustful.

Moreover, even in the conventional case, if you modify the inside of the microcontroller,
The problem can be solved, but there is no need to upgrade the microcomputer itself in order to control the temperature of the toilet seat.You can use the existing microcomputer-controlled sanitary washing device as is, separate the toilet seat switch from the microcomputer control, and use the w4-controlled device as is. The simple configuration of just connecting to the output end solves all the problems of conventional sanitary cleaning equipment at once, making it possible to significantly improve the reliability of sanitary cleaning equipment, and making it easier to manufacture than conventional sanitary cleaning equipment. It has excellent practical effects, such as being able to be used economically and thus being economical.
