(Explanation of heater part)
The heaters 12, 13, and 14 in the heater unit 3 are supplied from the commercial power supply 6 according to the temperatures detected by the sensors 12 a, 13 a, and 14 a provided corresponding to the heaters 12, 13, and 14, respectively. It operates with power.

  This power supply is performed based on a predetermined control pattern, whereby the temperature of the toilet seat, warm water, and warm air is kept at appropriate temperatures.

  Moreover, the control patterns of the heaters 12, 13 and 14 are changed based on the voltage detected by the voltage detection circuit 8.

  That is, the heater unit 3 performs phase control as the first control pattern when the voltage detected by the voltage detection circuit 8 is equal to or higher than a predetermined value (for example, 150V), and when the voltage is lower than the predetermined value. Pattern control as the second control pattern is performed.

  As a result, since it is possible to control with a control pattern suitable for the supplied voltage, it is possible to provide the toilet device 1 that does not require changing the specifications of the heaters 12, 13, and 14 even in regions where the power supply voltages are different. it can.

  The control pattern used here is such that the control pattern used for phase control is first control pattern information, and the control pattern used for pattern control is stored in advance in the storage means 16 as second control pattern information. The control means 15 selects any one of the control pattern information based on the voltage detected by the voltage detection circuit 8 and performs energization control on each of the heaters 12, 13, and 14.

  The first control pattern information used for phase control refers to the power corresponding to a part of the waveform for each half wave of the waveform obtained by full-wave rectification of the alternating current supplied from the commercial power source 6. Control information for controlling the power supplied to the heaters 12, 13, and 14 by turning on / off the power supply switch 22 (see FIG. 4) so as to be supplied to 12, 13, and 14. .

  As shown in FIG. 2, the phase control pattern corresponding to the first control pattern information is the first period t1 from the zero cross point of the waveform obtained by full-wave rectifying the alternating current supplied from the commercial power source 6. And a switch circuit 21 which will be described later is turned on only during the second period t2 until the next zero cross point, and the switch circuit 21 is turned off during the period from the first period t1 to the second period t2. It is a pattern.

  The power supplied to each heater 12, 13, and 14 is controlled by adjusting the time of the first period t1 and the second period t2, and corresponds to the area of the hatched portion in FIG. The supplied electric power is supplied to the heaters 12, 13 and 14.

  As described above, when the voltage of the commercial power source 6 is higher than a predetermined value, the phase control as shown in FIG. 2 is performed, so that the follow-up performance of the temperature control of each heater 12, 13, and 14 is improved as compared with the pattern control. Can be improved.

  In addition, in this control pattern, the start point and end point of the first period t1 and the start point and end point of the second period t2 are set with reference to the zero cross point, so that the heaters 12, 13, and 14 are referred to. When the current is turned on / off, the voltage applied to each of the heaters 12, 13, and 14 can be set to an arbitrary voltage or less, so that noise generated by phase control can be reduced.

  Also, the second control pattern information used for pattern control refers to whether power corresponding to the waveform is supplied for each half wave of the waveform obtained by full-wave rectifying the alternating current supplied from the commercial power source 6. This is control information for controlling the power supplied to the heaters 12, 13, and 14 depending on whether or not.

  The control pattern for pattern control corresponding to the second control pattern information is a unit of a waveform obtained by full-wave rectifying the alternating current supplied from the commercial power supply 6 as shown in FIGS. And a control pattern for controlling energization and non-energization (on and off of the switch circuit 21) to the heaters 12, 13, and 14 in half-wave units. In this pattern control, power corresponding to the area of the shaded area in FIG. 3 is supplied to each heater 12, 13, 14.

  That is, when 50% of the electric power supplied from the commercial power source 6 is supplied to the heaters 12, 13, and 14, the AC supplied from the commercial power source 6 is shown in FIG. The energization control is performed by a pattern in which the energization state for the half wave of the waveform obtained by full-wave rectification of the current is made, and then the non-energization control for the half wave is repeated.

  When 25% of the electric power supplied from the commercial power source 6 is supplied to each heater, the AC current supplied from the commercial power source 6 is full-wave rectified as shown in FIG. The energization control is performed by a pattern in which the energization state is performed for the half wave period of the waveform and then the non-energization state is performed for the quarter wave period.

  As described above, when the voltage of the commercial power source 6 is lower than the predetermined value, pattern control as shown in FIGS. 3A and 3B is performed, and the energization start point and end point are both zero-crossed. Since it coincides with the point, noise generated when switching between the energized state and the non-energized state can be reduced.

  Hereinafter, each circuit for controlling energization of the hot water heater 13 by the toilet apparatus 1 will be described in detail with reference to FIG. In FIG. 4, only the portion related to the control of the hot water heater 13 is illustrated in the toilet apparatus 1, and the energization control is also performed on the toilet seat heater 12 and the hot air heater 14 by the same circuit, and therefore the description thereof is as follows.

  As shown in FIG. 4, the switching power supply circuit 7 included in the toilet apparatus 1 includes a diode bridge 17 that rectifies an AC commercial power supply 6, a capacitor C <b> 1 that smoothes the current rectified by the diode bridge 17, and the capacitor A transformer 18 for stepping down the voltage of the current smoothed by C1 to a predetermined voltage, a switching transistor T1 for switching on / off of the current flowing through the transformer 18, and a driving voltage for the switching IC 19 for controlling the operation of the switching transistor T1 (VCC25) and a predetermined voltage supply circuit 30 for supplying a voltage (VCC25) to be applied to the source of the phototransistor PT2 of the switch circuit 21 to be described later.

  The switching power supply circuit 7 turns on and off the switching transistor T1 at a predetermined timing based on a control signal input from the switching IC 19 to thereby generate a direct current flowing through the temporary side coil 18a of the transformer 18 at a predetermined frequency. Thus, an alternating current that has been stepped down to a predetermined voltage flows through the secondary coil 18b.

  The predetermined voltage generation circuit 30 includes a resistor R30, a capacitor C30, a coil 18c, and a diode D30.

  When the switching power supply circuit 7 starts to operate, first, the capacitor C30 is charged with a predetermined amount of charge by the alternating current supplied from the commercial power supply 6, and the charge charged by the capacitor C30 is discharged. The driving voltage (VCC25) of the switching IC 19 and the voltage (VCC25) applied to the source of the phototransistor PT2 of the switch circuit 21 are supplied.

  Thereafter, after the switching IC 19 starts to operate, the capacitor C30 charges and discharges a predetermined amount of electric charge by a current generated in the coil 18c in accordance with the voltage excited in the secondary side coil 18b of the transformer 18, and the switch circuit The voltage (VCC25) to be applied to the source of the 21 phototransistor PT2 is supplied.

  The voltage detection circuit 8 is a circuit that detects the voltage applied to the hot water heater 13 based on the time during which an alternating current is flowing in the secondary side coil 18b of the switching power supply circuit 7 (on time of the transformer 18). It is composed of two resistors R1 and R2 connected in series and two protective diodes D1 and D2 connected in series.

  The zero-cross detection circuit 9 includes a photocoupler 20, a power supply voltage is applied to the input side of the photocoupler 20 (both ends of the light emitting diodes LED 1 and LED 2), and power is supplied from the output side of the photocoupler 20 (phototransistor PT 1). A signal that detects the zero cross point of the waveform is input to the microcomputer 2.

  At this time, the light emitting diodes LED1 and LED2 emit light at the timing when the value of the power supply voltage becomes 0V or near 0V, and the phototransistor PT1 is turned on by this light.

  As a result, a signal that rises at a timing when the power supply voltage becomes 0 V or near 0 V is input to the microcomputer 2, and the timing at which the signal input from the photocoupler 20 to the microcomputer 2 rises as a zero cross point of the power supply voltage. Be recognized.

  Further, a switch circuit 21 is provided between the hot water heater 13 and the commercial power source 6, and the hot water heater 13 is switched between energization and non-energization by turning on / off the switch circuit 21. The electric power supplied to 13 is controlled.

  The switch circuit 21 includes a switch 22 and a coil 23 connected to the transistor T2.

  The switch circuit 21 includes a photocoupler 40 for supplying power and a transistor T40 for supplying power.

  In the photocoupler 40 for supplying power, the light emitting diode LED 40 is turned on and off at the timing based on the control signal input from the microcomputer 2, and the phototransistor PT40 is turned on only for the time when the light emitting diode LED 40 is turned on. Become.

  The power supply transistor T40 is configured to be in an on state only while the phototransistor PT40 of the power supply photocoupler 40 is in an on state, and to supply power from the commercial power source 6 to the hot water heater 13.

  In addition, the code | symbol 17a shown in FIG. 4 is a diode bridge provided in order to prevent that the negative voltage is applied to the hot water heater 13 from the commercial power source 6. FIG.

  Further, a fuse 24 is provided between the commercial power source 6 and the hot water heater 13. When the power supply voltage exceeds 300 V, the fuse 24 is blown, and an abnormally high voltage is applied to the hot water heater 13, so that the hot water heater 13 is turned on. It tries to prevent it from being damaged.

  Hereinafter, operation | movement of the toilet apparatus 1 comprised in this way is demonstrated concretely. In the following description, the energization control of the hot water heater 13 will be described as an example. The energization control of the toilet seat heater 12 and the hot air heater 14 is almost the same as the energization control of the hot water heater 13 except that the rated power values are different. Since it is the same, the description will be omitted.

  The control means 15 in the toilet apparatus 1 of 1st Embodiment performs electricity supply control with respect to the warm water heater 13 according to the flowchart shown in FIG.

  First, when the commercial power supply 6 is turned on to the toilet apparatus 1 (step S1), the control means 15 detects the voltage of the turned on commercial power supply 6 (step S2).

  Next, the control means 15 determines whether or not the power supply voltage has exceeded a predetermined value of 300 V (step S3).

  Here, when it is determined that the power supply voltage exceeds 300 V, the control unit 15 causes the display 5 to display that an abnormally high voltage is supplied to the toilet device 1 by operating the display driving unit 5b ( Step S10) After that, the operation is stopped (Step S11), and the process is terminated. When it is determined that the power supply voltage does not exceed 300V, the process proceeds to Step S4. Even if the power supply voltage exceeds 300 V here, the fuse 24 is disconnected as described above even when the voltage detection circuit 8 cannot detect this. The heater 13 is not damaged by overvoltage.

  Thus, by displaying on the display 5 that an abnormally high voltage is being supplied to the toilet device 1, the user can be appropriately notified of the abnormality, and the toilet device 1 from the abnormally high voltage. Can be protected.

  In step S4, the control means 15 determines whether the power supply voltage is equal to or higher than a predetermined value of 150V or whether the power supply voltage is less than 150V.

  When the control unit 15 determines that the power supply voltage is 150 V or higher, the control unit 15 uses the phase control for the control pattern information for phase control that is the first control pattern information from the storage unit 16 and the hot water heater 13. An operation program for performing energization control is read (step S5).

  Next, the control means 15 performs energization control by phase control on the hot water heater 13 based on the control pattern information and the operation program read from the storage means 16 in step S5 (step S6).

  Next, the control means 15 detects the voltage applied to the hot water heater 13 from the commercial power source 6, determines whether or not the detected voltage exceeds 300V (step S7), and the power source voltage exceeds 300V. If it is determined that it is not, the process returns to step S6, and the process of step 6 and the process of step 7 are repeatedly repeated until the power supply from the commercial power source 6 is stopped.

  On the other hand, when the control means 15 determines in step S7 that the power supply voltage exceeds 300V, the display drive unit 5b is operated to indicate that an abnormally high voltage is being applied to the hot water heater 13. 5 (step S8), and then the energization to the hot water heater 13 is stopped (step S9), and the process is terminated.

  In step S4, when the control unit 15 determines that the power supply voltage is less than 150 V, the control unit 15 applies the pattern control control pattern information, which is the second control pattern information, from the storage unit 16 to the hot water heater 13. An operation program for performing energization control by pattern control is read (step S12).

  Next, the control means 15 performs energization control by pattern control on the hot water heater 13 based on the control pattern information and the operation program read from the storage means 16 in step S12 (step S13).

  Next, the control means 15 detects the voltage applied to the hot water heater 13 from the commercial power source 6, and determines whether or not the detected voltage exceeds 300V (step S14), and the power source voltage exceeds 300V. If it is determined that it is not, the process returns to step S13, and the process of step S13 and the process of step 14 are repeatedly performed until the power supply from the commercial power source 6 is stopped.

  On the other hand, when the control means 15 determines in step S14 that the power supply voltage exceeds 300V, the display drive unit 5b is operated to indicate that an abnormally high voltage is being applied to the hot water heater 13. 5 (step S15), and then the energization to the hot water heater 13 is stopped (step S16), and the process is terminated.

  As described above, the toilet device 1 according to the first embodiment performs the energization control by selecting either the pattern control or the phase control according to the voltage value of the commercial power supply 6 detected by the voltage detection circuit 8. Therefore, even if it is installed in a country with a different power supply voltage, it is possible to perform energization control with a control pattern corresponding to the power supply voltage of that country, and power exceeding the rating is supplied to the hot water heater 13. Therefore, it can be installed and used in countries with different power supply voltages without changing the specifications of the hot water heater 13.

 In addition, when the toilet device 1 is used in Japan, it is generally used at a single-phase 100V in the home, but it can also be used at a single-phase 200V that has recently become widespread. Furthermore, even if it is used with a single-phase 100V, it is safe because it operates safely even when a ground tap of the indoor wiring floats due to some trouble and a voltage higher than the single-phase 100V is applied. .

(Second Embodiment)
In the first embodiment described above, the control pattern for the hot water heater 13 is changed depending on whether the voltage of the commercial power source 6 is a predetermined value of 150 V or more or less than 150 V. In the second embodiment, however, In addition to the control, more appropriate energization control to the hot water heater 13 is made possible by the voltage detected by the voltage detection circuit 8.

  In step S28, the control means 15 operates the display driving unit 5b to display on the display 5 that an abnormality has occurred in the toilet apparatus 1 (step S28), and then stops energizing the hot water heater 13 after that. The process ends. Even if the power supply voltage exceeds 300 V here, the fuse 24 is disconnected as described above even when the voltage detection circuit 8 cannot detect this. The heater 13 is not damaged by overvoltage.

  In step S25, the control means 15 compares the voltage of the operating voltage condition information read in step S22 with the voltage value acquired from the voltage detection circuit 8, and moves the process to step S26 if it is determined that they match. If it is determined that they do not match, the process proceeds to step S28 to display on the display 5 that an abnormality has occurred in the toilet apparatus 1, and then the energization to the hot water heater 13 is stopped and the control is terminated. To do.

  In step S26, the control means 15 selects either one of the pattern control or the phase control based on the operating voltage condition information read in step S22, and performs energization control to the hot water heater 13.

  At this time, the control means 15 feedback-controls the hot water heater 13 while referring to the temperature information of the hot water input from the hot water sensor 13a, and the hot water temperature exceeds the upper and lower limits of the hot water temperature in the preset country. Energization control is performed so as not to occur.

  Further, after performing the energization control based on the operating voltage condition information, the control means 15 determines whether or not the voltage of the commercial power supply 6 exceeds 300V (step S27), and the power supply voltage exceeds 300V. If it is determined that there is not, the process proceeds to step S26, and step S26 and step S27 are continuously repeated until the power supply from the commercial power supply 6 is stopped, and it is determined that the power supply voltage exceeds 300V. If so, the process moves to step S30.

  In step S30, the control means 15 operates the display drive unit 5b to display on the display 5 that an abnormality has occurred in the toilet apparatus 1, and then stops energization of the hot water heater 13 and ends the control. .
