The controller 30 is provided with a nonvolatile storage unit. The warm air fan 20 includes a blower 21 and an air heater 22. In order to measure the temperature of the circuit board (not shown) of the controller 30, a thermistor 24 is installed in the vicinity of the circuit board in the toilet seat box 11.
[0050]
  The controller 30 for controlling the hot water washing apparatus and the heating toilet seat exchanges signals with a controller 40 such as a remote controller, and also outputs temperature signals from the thermistors 5 and 24 and a thermistor (not shown) provided in the toilet seat body 12. Is entered.
[0051]
  In addition to the liquid crystal display panel 41, the controller 40 includes a washing switch 42, a hot air switch 43, a stop switch 44, a heating toilet seat switch 45, a temperature switch 46 for adjusting the temperature of the hot water, hot air or the heating toilet seat, and a sound. A speaker 47 is provided for generation.
[0052]
  When the cleaning switch 42 is pressed, the main valve 2 is opened, hot water is ejected from the cleaning nozzle 9, and when the stop switch 44 is pressed, the main valve 2 is closed and the hot water is stopped.
[0053]
  When the hot air switch 43 is pressed, the hot air blows out from the hot air fan 20, and when the stop switch 44 is pressed, the hot air stops. When the heating toilet seat switch 45 is pressed, the heater 13 of the heating toilet seat 10 is energized to warm the toilet seat, and when the heating toilet seat switch 45 is pressed once more, the energization of the heater 13 is stopped.
[0054]
  The temperature of the heating toilet seat 10 is adjusted by operating the temperature switch 46 in a state where the heating toilet seat switch 45 is turned on and neither the buttock cleaning nor the hot air drying is performed, and the temperature switch 46 is in a state where hot water is being blown out. The hot water temperature is adjusted by operating. The hot air temperature is adjusted by operating the temperature switch 46 while the hot air is blown out.

That is, after a service person dispatched from the service center performs maintenance, a reset signal is generated by operating the switches 42 to 46 according to a specific pattern, and the storage time of the nonvolatile storage unit is canceled. Resumes. Accordingly, when the set time elapses after the previous maintenance, the display is performed again, and the maintenance can be received again. In this case, the set time after the second time is 90% of the set time before that. This takes into account the aging of each part. In addition, instead of decreasing by 10%, it may be decreased by a certain width. Moreover, although it reduces to the 2nd time or the 3rd time etc., you may set to the same time as the last time after the 3rd time or the 4th time. This “90%” is an example, and it is obvious that other% values may be used.
[0059]

It squirts diagonally upward and is poured onto the buttocks of the seated person of the heating toilet seat 10. Although not shown, the pump 5 may be omitted by supplying hot water to the nozzle 9 by the supply water pressure, and a valve whose opening degree is controlled by the controller 30 may be provided instead. Since other configurations are exactly the same as those in FIG. 1, the same parts are denoted by the same reference numerals and description thereof is omitted.
[0070]
  Figure 9 is the simplestAccording to reference examplesA control example is shown. The non-volatile provided in the controller 30 starting from when the hot water washing device and the heated toilet seat are first energized or when a battery is first attached to the controller, or when any one of the switches 42 to 46 is operated for the first time. The storage unit stores the elapsed time.
[0071]
  In such a hot water washing apparatus and a heating toilet seat, a service man call such as “contact the service center” on the liquid crystal panel 41 after a set time T has elapsed after the manufacture, installation, or start of use of the apparatus. Is displayed, the output of at least one of the heaters 4 and 22 is decreased, the rotational speed of the pump 5 is decreased, and the rotational speed of the blower 21 is decreased. As a result, maintenance can be performed before the device reaches the end of its life and a failure occurs, and the failure is prevented in advance.
[0072]
  Of FIG.According to reference examplesThe flowchart shown in FIG. 9 is characterized by comprising means for resetting the set time. That is, after a service person dispatched from the service center performs maintenance, a reset signal is generated by operating the switches 42 to 46 according to a specific pattern, and the storage time of the nonvolatile storage unit is canceled. Resumes. Accordingly, when the set time elapses after the previous maintenance, the display is performed again, the output of at least one of the heaters 4 and 22 is decreased, the rotational speed of the pump 5 is decreased, and the rotational speed of the blower 21 is decreased. Can receive. In this case, the set time after the second time is 90% of the set time before that. This takes into account the aging of each part. In addition, instead of decreasing by 10%, it may be decreased by a certain width. Moreover, although it reduces to the 2nd time or the 3rd time etc., you may set to the same time as the last time after the 3rd time or the 4th time. This “90%” is an example, and it is obvious that other% values may be used.
[0073]
  Of FIG.According to the embodimentThe flowchart in FIG. 10 is the first set time T as the set time.₁And a second set time T longer than that₂And the first set time T₁At the same time, a service man call is displayed on the liquid crystal panel 41, and the output of at least one of the heaters 4 and 22 is reduced, the rotational speed of the pump 5 is reduced, and the rotational speed of the blower 21 is reduced. Second set time T₂Is reached, the energization of at least one of the heaters 4, 13, 22 is stopped, the main valve 2 is closed, or at least one of the pump 5 and the blower 21 is stopped.
[0074]
  In such a device, the first set time T₁If you do not receive maintenance when you arrive, the second set time T₂Since the buttock washing water, the buttock drying air and the heating toilet seat 10 do not get warm, or the buttock washing water and the buttock drying air do not come out, it is possible to make the user strongly feel the necessity of maintenance.
[0075]
  Obviously, these devices may also include means for resetting the set water amount and the set load after maintenance. Further, in this case, the set water amount and the set load after the second time may be smaller than the set water amount and the set load before that. Further, a first set amount and a second set amount larger than the first set amount are set as the set water amount and the set load, and when the first set amount is reached, the display is performed and at least 1 is set. The output of the two heaters 4, 22 is reduced, the rotational speed of the pump 5 is reduced, and the rotational speed of the blower 21 is reduced. When the second set amount is reached, energization of at least some of the heaters is stopped, 5 or the blower 21 may be stopped, or the main valve 2 may be forcibly closed. When the energization of the heaters 4 and 22 is stopped, only cold water and wind are emitted. When the energization of the heater 13 is stopped, the toilet seat is cooled, and when the blower 21 is stopped, the wind is not emitted. When the valve 2 is forcibly closed or the pump 5 is stopped, water does not come out, and in any case, the user strongly feels the necessity for maintenance.
[0076]
  In the control of FIG.₂Longer than the third set time T₃And the second set time T₂Is reached, the energization amount to at least one of the heaters 4, 13, and 22 is decreased, or the rotational speed of at least one of the pump 5 and the blower 21 is decreased, and the third set time T₃When reaching the above, energization to at least one of the heaters 4, 13, and 22 may be stopped, the main valve 2 may be closed, or at least one of the pump 5 and the blower 21 may be stopped.

  FIG. 5 is a perspective view of the heating toilet seat according to the embodiment of the present invention, and FIGS.According to the embodimentIt is a flowchart which shows the example of control.
[0084]
  1 and 8, a heated toilet seat 60 is attached to the toilet seat box 50 so as to be rotatable in the vertical direction. This heating toilet seat 60 is a toilet seat body 62 provided with a heater 63. The toilet seat box 50 includes a rotation detection sensor 51 that detects the vertical rotation of the heating toilet seat 60, a load sensor 52 that detects the weight of a person seated on the heating toilet seat 60, and a volume 53 that adjusts the temperature of the heater 63. A power switch 54, and a lamp 55 such as an LED that is lit only when the power switch 54 is ON.
[0085]
  The controller (not shown in FIG. 5) provided in the toilet seat box 50 receives the detection signals of these sensors 51 and 52 and the signal of the volume 53, and the controller controls the energization of the heater 63. The heater 63 is energized by a lead wire that is provided so as to connect the toilet seat box 50 and the toilet seat body 62 or is inserted through a support shaft (not shown) of the toilet seat body 62.
[0086]
  This lead wire is damaged little by little by the vertical rotation of the heating toilet seat 60. Therefore, in FIG. 6, the number of up and down rotations is stored in a number memory formed of a non-volatile storage unit, and the number of up and down rotations is defined as K₁If the lamp reaches 55, the lamp 55 blinks and a warning is issued. If the maintenance is not received in spite of this warning, the number of vertical rotations is K₁More than K₂Is reached, the power supply to the heater 63 is stopped. When maintenance is performed in response to the blinking of the lamp 55, for example, the service person cancels the storage of the number-of-times memory by operating a cancel switch provided in the controller. At this time, the specified number of times K thereafter₁Is the previous K₁It may be smaller than the value.
[0087]
  K₂More than K₃Is set further, K₂The amount of current supplied to the heater 63 is reduced when K is reached.₃When the temperature reaches the value, the energization to the heater 63 may be stopped.
[0088]
  A load is applied to the heating toilet seat 60 depending on the weight of the person sitting on the heating toilet seat 60, and the support shaft and the like are gradually deteriorated. In addition, a warning may be issued.

  FIG. 7 shows an example of this control, in which the number of up / down rotations detected by the sensor 51 is accumulated in a load memory composed of a non-volatile storage unit, and the load load is detected from the load detected by the load sensor 52 when seated. Is calculated. For example, it is assumed that the weight corresponds to 0.01 times of vertical rotation per 1 kg of weight, and a value obtained by multiplying the load by 0.01 is set as the load equivalent to the number of vertical rotations, and this is added to the above-mentioned number of vertical rotations. Stored in the load memory. The coefficient 0.01 is an example, and may be appropriately selected according to the model, the constituent material of the toilet seat body 62, and the like.
[0090]
  The total load integrated value L based on both the number of vertical rotations and the seating load is a specified L₁When it reaches, a warning is given by flashing the lamp 55, and when it is ignored, the load is low.₂(L₁The power to the heater 63 is stopped. When maintenance is received in response to the blinking of the lamp 55, the storage of the load memory is canceled.
[0091]
  L₂Greater than L₃To further set L₂When the power reaches the heater 63, the energization amount to the heater 63 is decreased, and L₃When the temperature reaches the value, the energization to the heater 63 may be stopped.
[0092]
  FIG. 12 shows another example of the heating toilet seat with the hot water cleaning device of FIG.According to the embodimentIt is a flowchart which shows the example of control.
[0093]
  In this control example, the number of up and down rotations of the heating toilet seat 60 is stored in a number memory composed of a non-volatile storage unit, and the number of up and down rotations is defined as K₁When the temperature reaches, the lamp 55 is blinked to issue a warning, and at least one of the hot water temperature, the hot water amount, the hot air temperature of the hot air fan, and the hot air amount of the hot water cleaning device is reduced. If maintenance is not received despite this warning, the number of vertical rotations is K₁More than K₂When the temperature reaches the value, the energization of the heater 63 is stopped, or at least one of the hot water spraying stop, the water heating stop, the hot air blowing stop, and the wind heating stop of the hot water cleaning device is performed. When maintenance is performed in response to the blinking of the lamp 55, for example, the service person cancels the storage of the number-of-times memory by operating a cancel switch provided in the controller. At this time, the specified number of times K thereafter₁Is the previous K₁It may be smaller than the value.
[0094]
  K₂More than K₃Is set further, K₂The amount of current supplied to the heater 63 is reduced when K is reached.₃When the temperature reaches the value, the energization to the heater 63 may be stopped.
[0095]
  Similar to the control of FIG. 7, a load is applied to the heating toilet seat 60 depending on the weight of the person sitting on the heating toilet seat 60, and the support shaft and the like are gradually deteriorated. Alternatively, a warning may be issued in consideration of the load due to the weight of the seated person.
[0096]
  Figure 13 shows thisAccording to the embodimentIn this control example, the number of up / down rotations detected by the sensor 51 is accumulated in a load memory including a nonvolatile storage unit, and the load load is calculated from the load detected by the load sensor 52 when seated. For example, it is assumed that the weight corresponds to 0.01 times of vertical rotation per 1 kg of weight, and a value obtained by multiplying the load by 0.01 is set as the load equivalent to the number of vertical rotations, and this is added to the above-mentioned number of vertical rotations. Stored in the load memory. The coefficient 0.01 is an example, and may be appropriately selected according to the model, the constituent material of the toilet seat body 62, and the like.
[0097]
  The total load integrated value L based on both the number of vertical rotations and the seating load is a specified L₁When the temperature reaches the value, the lamp 55 blinks to issue a warning, and at least one of the hot water temperature, the hot water amount, the hot air temperature of the hot air fan, and the hot air amount of the hot water cleaning device is reduced. When it is ignored, the load is L₂(L₁Is stopped, or the heater 63 is deenergized, or at least one of the hot water washing stop, the water heating stop, the hot air blowing stop, and the wind heating stop of the hot water cleaning device is performed. . When maintenance is received in response to the first warning such as blinking of the lamp 55 or a decrease in hot water temperature, the storage of the load memory is canceled.
[0098]
  L₂L greater than₃To further set L₂When the power reaches the heater 63, the energization amount to the heater 63 is decreased, and L₃When the temperature reaches the value, the energization to the heater 63 may be stopped.
