Figure 11 (a) is the oscillogram of explanation electric current of flowing through lamps heater 480 during 480 watts of drivings, and Figure 11 (b) is explanation is imposed on the energising control signal of heating element drive division 230 by the current on time commutation circuit during 1200 watts of drivings oscillogram.
Shown in Figure 11 (b), when driving for 1200 watts, the logical value of energising control signal is always " 1 ".When the logical value of energising control signal was " 1 ", heater-driven section 230 made the alternating current that provides from power circuit flow through lamp heater 480 (the thick line part Figure 11 (a)).Therefore, during whole cycle whole in, alternating current all flows through lamp heater 480.As a result, with about 1200 watts power drive lamp heater 480.
Figure 12 (a) is the oscillogram of explanation electric current of flowing through lamps heater 480 during 660 watts of drivings, and Figure 12 (b) illustrates the oscillogram that is imposed on the energising control signal of heating element drive division 230 during 600 watts of drivings by the current on time commutation circuit.
Shown in Figure 12 (b), when driving for 600 watts, the energising control signal is made of the cycle pulse identical with the alternating current of supplying with heating element drive division 230.The dutycycle of pulse is set as 50%.
When the logical value of energising control signal was " 1 ", heater-driven section 230 made the alternating current that provides from power circuit flow through lamp heater 480 (the thick line part Figure 12 (a)).Therefore, during half period in, alternating current flows through lamp heater 480.As a result, with about 600 watts power drive lamp heater 480.
Figure 13 (a) is the oscillogram of explanation electric current of flowing through lamps heater 480 during low-power drives, and Figure 13 (b) is explanation is imposed on the energising control signal of heating element drive division 230 by the current on time commutation circuit during low-power drives oscillogram.
Shown in Figure 13 (b), when driving for 600 watts, the energising control signal is made of the cycle pulse identical with the alternating current that offers heating element drive division 230.The dutycycle of pulse is set as than 50% little (for example about about little a few percent).
When the logical value of energising control signal was " 1 ", heater-driven section 230 made the alternating current that provides from power circuit flow through lamp heater 480 (the thick line part Figure 13 (a)).Within each cycle, alternating current flows through lamp heater 480 during corresponding with pulse width.As a result, for example with about 50 watts power drive lamp heater 480.
When the temperature that reduces toilet seat section 400 with additive method, or the heating function of toilet seat apparatus 100 is when being closed, and the current on time commutation circuit control signal of will not switching on sends to heater-driven section 230 (energising control signal sets is logical value " 0 ").Like this, heater-driven section 230 does not drive lamp heater 480.
Generally speaking, when the electric current that imposes on electronic component has the higher hamonic wave composition, will produce noise.In the present embodiment, as mentioned above, when lamp heater 480 is carried out 1200 watts of drivings or 600 watts of drivings, impose on the electric current of lamp heater 480 with the sine curve trail change, therefore, even electric current increases, also can fully fall low noise generation.
And when the low-power of carrying out lamp heater 480 drove, the electric current of supplying with lamp heater 480 had the higher hamonic wave composition, but compares with 600 watts of drivings with 1200 watts of drivings, and electric current is very little.Therefore, low noise generation can fully be fallen.
As mentioned above, in the present embodiment, although with 1200 watts, 600 watts and about 50 watts power drive lamp heater 480, also can be with other big or small power drive lamp heaters 480.
For example, when stream has alternating current in the lamp heater 480 in during half period, set the time of flowing through alternating current with the interval of the predetermined periods such as two or three cycles.Lamp heater 480 can be 1200 watts, 600 watts and about 50 watts power drive that varies in size by scope like this, and fully prevents the generation of noise.
In the following description, current on time is defined as, and alternating current flows through the time (it is the time of the logical value in the energising control signal for " 1 ") of lamp heater 480 and the ratio of the one-period of alternating current.
In this embodiment, when the logical value of energising control signal was " 1 ", control part 210 was supplied with electric current to lamp heater 480, and when the logical value of energising control signal was " 0 ", control part 210 stopped to supply with electric current to lamp heater 480.But, the logical value that also can work as the control signal of switching on is during for " 1 ", and control part 210 stops to supply with electric currents to lamp heater 480, and when the logical value of energising control signal be " 0 ", control part 210 was to lamp heater 480 supply electric currents.
(7) method of making heater control table
(7-a) inrush current
In the toilet seat apparatus 100 of this embodiment, when the instantaneous rising of temperature of toilet seat section 400, there is larger electric current to flow through lamp heater 480.In the case, in the relatively large inrush current of lamp heater 480 interior appearance.
When larger inrush current occurring, tie breaker is owing to overcurrent disconnects, and pressure drop occurs in being connected to the power distribution of toilet seat apparatus 100.
Therefore, when making the heater control table, preferred mode is that a plurality of heater control models are set, with abundant reduction inrush current.
In the example of the heater control table of Fig. 8 to Figure 10, set following heater control model, before being about to that lamp heater 480 carried out 1200 watts of drivings, carry out first 600 watts of drivings.In Fig. 8 to Figure 10, will carry out 1200 watts of drivings, 600 watts of drivings before as 600 watts of drivings for reducing inrush current.
(7-b) overshoot
As mentioned above, in order to make the temperature moment rising of toilet seat section 400 by lamp heater 480, larger electric current flows through lamp heater 480.Therefore, overshoot appears in the variations in temperature of toilet seat section 400.Therefore, be difficult at short notice temperature stabilization with toilet seat section 400 at the toilet seat design temperature.
In this embodiment, when making the heater control table, set a plurality of heater control models, with the overshoot of the variations in temperature of abundant reduction toilet seat section 400.
In the example of Fig. 8 to Figure 10, for the overshoot of the variations in temperature that prevents toilet seat section 400, set the driving that drives heaters 480 when heating up in toilet seat section 400 with two stage control lamps for.
(7-c) critical-temperature
In the toilet seat apparatus 100 with heating function, preferably can not make the user that the 410T of section that feels to take one's seat is ice-cold.Hereinafter, the minimum temperature that the user can not felt the ice-cold 410T of the section of taking one's seat is called " critical-temperature ".
Therefore, preferred mode is to enter the toilet and take when taking one's seat the 410T of section as the user, and the temperature of the 410T of section that takes one's seat should be higher than critical-temperature at least.
Therefore, when making the heater control table, set a plurality of heater control models, enter the toilet is warmed up to critical-temperature to the surface of the 410T of section that takes one's seat time with abundant shortening from the user.And according to inventor's experimental result, critical-temperature is approximately 29 ℃.
In the example of the heater control table of Fig. 8 to Figure 10, because the temperature of toilet seat section 400 rises to rapidly critical-temperature, when the measurement temperature value when the user enters the toilet is lower than critical-temperature, sets for lamp heater 480 is carried out 1200 watts of drivings.
(7-d) take one's seat section and sendible temperature
It is different from the real surface temperature of the 410T of section that takes one's seat that the user takes the temperature (sendible temperature) of feeling when taking one's seat the 410T of section.
Usually, the sendible temperature of feeling when human body and specific object contact is along with the heat conductivility of object and the variations such as heat capacity difference between human body and the object.
Therefore, such a case occurs: the real surface temperature of the 410T of section that takes one's seat and user take between the sendible temperature of feeling when taking one's seat the 410T of section deviation.
In this embodiment, the 410T of section that takes one's seat is made by the aluminium with excellent heat conductivity performance.
Like this, for example when the temperature of the 410T of section that takes one's seat was lower than user's body temperature, because user's body temperature is delivered to rapidly the 410T of section that takes one's seat at short notice, so user's sendible temperature was lower than the actual temperature of the 410T of section that takes one's seat.
Therefore, when making the heater control table, set a plurality of heater control models, the sendible temperature the when user is taken one's seat is as much as possible near the toilet seat design temperature.
(7-e) lamp heter temperature and the relation between section's surface temperature of taking one's seat
When the temperature of toilet seat section 400 raises, between the real surface temperature of the surface temperature (temperature of glass tube) of lamp heater 480 and the 410T of section that takes one's seat, there is larger temperature difference.
Therefore, for the surface temperature of the 410T of section that will take one's seat is brought up to the toilet seat design temperature and stably maintained this temperature, when beginning, the driving of lamp heater 480 needs the scheduled time.
Therefore, the inventor begins test below having carried out of time that surface temperature up to the 410T of section that takes one's seat is stabilized in the toilet seat design temperature (toilet seat heat up test) for the driving from lamp heater 480.
When the room temperature in the toilet is 25 ℃, the toilet seat design temperature is set as about 40 ℃.Under this state, drive lamp heater 480.Required time when the surface temperature of then, measuring the 410T of section that takes one's seat is stabilized in 40 ℃.Thereby obtain relation shown in Figure 14.
Figure 14 explanation relation between the surface temperature of the surface temperature of the 410T of section and lamp heater 480 of when toilet seat heats up test, taking one's seat.In Figure 14, the longitudinal axis represents temperature, and transverse axis represents the time.And, the surface temperature of heavy line indication lamp heater 480, thick dashed line represent the to take one's seat surface temperature of the 410T of section.
As shown in figure 14, because lamp heater 480 is driven, so the surface temperature of lamp heater 480 rose to 100 ℃ in about 10 seconds.Then, the surface temperature of lamp heater 480 stably maintains about 100 ℃.
Simultaneously, along with the variation of the surface temperature of lamp heater 480, the surface temperature of the 410T of section that takes one's seat slowly rises within about 10 seconds and reaches 40 ℃.Then, the take one's seat surface temperature of the 410T of section stably maintains about 45 ℃.
In this mode, the surface temperature of the 410T of section that for example takes one's seat and the difference of toilet seat design temperature increase along with the process of time, and this temperature difference is kept stable substantially after 10 seconds greatly.
That is to say, when the temperature controlled time was shorter than for 10 second, the surface temperature of the surface temperature of considering lamp heater 480 and the 410T of section that takes one's seat poor, the electric current of lamp heater 480 is flow through in very difficult control.
Therefore, when making the heater control table, consider for the power that drives lamp heater 480 and the temperature stabilization that makes the 410T of section that takes one's seat by this power and to have set a plurality of heater control models in the required time of toilet seat design temperature.
(7-f) the measurement temperature value of thermistor and the relation between section's surface temperature of taking one's seat
When the temperature of toilet seat section 400 raises, between the real surface temperature of the measurement temperature value of thermistor 411 and the 410T of the section of taking one's seat among Fig. 3 temperature difference appears.
Relation when therefore, the inventor raises to the temperature of toilet seat section 400 between the real surface temperature of the measurement temperature value of thermistor 411 and the 410T of section that takes one's seat has been carried out following test (measuring temperature value confirms to test).
When the room temperature in the toilet is 21 ℃, the toilet seat design temperature is set as about 38 ℃.Under this state, with scheduled time driving lamp heater 480.Required time when then, measuring the surface temperature of measuring temperature value and taking one's seat the 410T of section and be stabilized in about 38 ℃.Thereby obtain relation shown in Figure 15.
The relation of Figure 15 explanation between the measurement temperature value of the surface temperature of measuring the 410T of section that takes one's seat when temperature value is confirmed test and thermistor 411.In Figure 15, the longitudinal axis represents temperature, and transverse axis represents the time.And heavy line represents the measurement temperature value by thermistor 411, thick dashed line represent the to take one's seat surface temperature of the 410T of section.
As shown in figure 15, when making the temperature rising of toilet seat section 400 when driving lamp heater 480, between the surface temperature of measurement temperature value and the 410T of section that takes one's seat temperature difference appears.
In the example of Figure 15, driving the lamp heater after 480 about 4 seconds, the temperature difference between the surface temperature of measurement temperature value and the 410T of section that takes one's seat is approximately 2.5 ℃.
And although do not illustrate in the drawings, when measuring temperature value affirmation test with other states, the maximum temperature difference between the surface temperature of measurement temperature value and the 410T of section that takes one's seat is about 6 ℃.
That is to say, when toilet seat section 400 heats up, be difficult to according to the driving of being controlled exactly lamp heater 480 by the measurement temperature value of thermistor 411.
Therefore, when making the heater control table, consider for the power that drives lamp heater 480 and the temperature stabilization that makes the 410T of section that takes one's seat by this power in the required time of toilet seat design temperature a plurality of heater control models to be set.
And the heater control model can have the measurement temperature value when switching the power that is used for driving lamp heater 480.In the case, in advance by testing or simulate the relation of finding out between the surface temperature of measuring temperature value and the 410T of section that takes one's seat.Measurement temperature value when then, setting power switched.
In this mode, when the heater control model has the information relevant with the driving time of lamp heater 480 and when measuring the relevant information of temperature value, can control more accurately according to these information the driving of lamp heater 480.
In the example of Fig. 8 and Figure 10, except the timetable relevant with the driving of lamp heater 480, also set from 1200 watts of drivings and switched to 600 watts of measurement temperature values (inversion temperature) when driving.This inversion temperature is corresponding to the critical-temperature on the surface of the 410T of section that takes one's seat.
In the case, the measurement temperature value when the user enters the toilet is in 16 ℃ of-28 ℃ of scopes the time, and control part 210 is carried out 1200 watts of drivings of lamp heater 480 according to timetable, and control part 210 judges whether measure temperature values reaches inversion temperature.
Therefore, when the measurement temperature value reaches inversion temperature, carry out from 1200 watts of handover operations that are driven into 600 watts of drivings, and need not the consideration timetable.
And, in the example of Fig. 8 and Figure 10, also set the measurement temperature value (target temperature) when switching to low-power and drive from 600 watts of drivings.This target temperature stops to heat up and waits for the surface temperature of the 410T of the section of taking one's seat of the state that the user takes one's seat corresponding to being in.
In the case, control part 210 is according to 600 watts of drivings of timetable execution lamp heater 480, and control part 210 judges whether measure temperature values reaches target temperature.
Therefore, when the measurement temperature value changes temperature to target, carry out the handover operations that are driven into the low-power driving from 600 watts, and need not the consideration timetable.Therefore, the take one's seat surface temperature of the 410T of section maintains fixing level.
Low temperature when (7-g) preventing from taking one's seat is burnt
When human body and temperature during than the slightly high thermal source Long contact time of body temperature, the situation that the contact portion of human body is burnt by low temperature might appear.In this embodiment, when toilet seat design temperature during than user's fever, if the user is sitting on the toilet seat for a long time, then the situation that the user is burnt by low temperature might appear.
Therefore, when making the heater control table, preferred mode is to set a plurality of heater control models, thereby after the user takes toilet seat, along with the process of time, little by little reduces the temperature of the 410T of section that takes one's seat.
To the heater control model of heater control table shown in Figure 10, omitted the timetable after the user takes one's seat at Fig. 8.But, actual optimal way is the timetable of setting the power that is used for driving lamp heater 480, thereby after the user takes toilet seat, little by little reduces the surface temperature of the 410T of section that takes one's seat.
(8) according to the driving example of the lamp heater of heater control table
The surface temperature that Figure 16 illustrates the driving example of the lamp heater 480 that carries out according to the heater control table among Figure 10 and the 410T of section that takes one's seat changes (Fig. 4).
Current on time when the curve map of the take one's seat surface temperature of the 410T of section and the relation between the time being shown among Figure 16 and having driven lamp heater 480 and the curve map of the relation between the time.Transverse axis in two curve maps is common time shaft.
In this example, suppose that the user has opened heating function in advance, and set higher toilet seat design temperature (38 ℃).
As mentioned above, when waiting in the winter time room temperature to be lower than in 18 ℃ the situation of standby temperature, control part 210 (Fig. 3) is with the adjustment to 18 of toilet seat section 400 ℃.In this mode, D1 detected the standby of user before entering the toilet by the detecting sensor 600 of entering the room during, the low-power that control part 210 is carried out lamp heaters 480 drives, thus the surface temperature of the 410T of section that will take one's seat maintains 18 ℃.
When entering the room detecting sensor 600 when moment t1 detects the user and enters the toilet, control part 210 is D2 during inrush current reduces, and carries out 600 watts of drivings of lamp heater 480 according to the heater control table among Figure 10.And carrying out 600 watts of drivings is in order fully to reduce inrush current.In the case, take one's seat the surface temperature of the 410T of section along the second thermograde rising.
Then, the moment t2 during reducing through inrush current behind the D2, control part 210 begins to carry out 1200 watts of drivings of lamp heater 480, and the lasting 1200 watts of drivings carrying out lamp heater 480 of D3 between the first temperature raising period.In the case, the take one's seat surface temperature of the 410T of section rises along above-mentioned the first thermograde.
At this moment, the take one's seat surface temperature of the 410T of section rises rapidly sharply.Carry out 1200 watts of drivings of lamp heater 480, until the surface temperature of the 410T of section that takes one's seat reaches critical-temperature always.In the curve map of surface temperature of the 410T of section was taken one's seat in the expression of Figure 16, dotted line represented to be approximately 29 ℃ critical-temperature.The measurement temperature value supposed when the surface temperature of the 410T of section reaches critical-temperature of taking one's seat when 1200 watts of carrying out lamp heater 480 are driven is defined as the inversion temperature among Figure 10.
The time t3 that the surface temperature of the 410T of section of taking one's seat reaches critical-temperature reaches short period in time of the inversion temperature of being determined by the heater control table for time of 1200 watts of drivings being determined by the heater control table with until measure temperature value.
In this mode, between the first temperature raising period in the D3, by carrying out 1200 watts driving, the surface temperature of the 410T of section that takes one's seat rises to rapidly critical-temperature.Like this, even the above-mentioned LED280 of informing (Fig. 1) does not open, the user also can be seated comfortably in the toilet seat section 400, can not feel the ice-cold of the 410T of section of taking one's seat.
As mentioned above, when the surface temperature of the 410T of section that takes one's seat rose rapidly, overshoot appearred in variations in temperature.But, in this embodiment, because when the surface temperature of the 410T of section that takes one's seat reached critical-temperature, 1200 watts of drivings of lamp heater 480 were switched to 600 watts of drivings, overshoot appears in the surface temperature variation of the 410T of section even therefore take one's seat, and surface temperature can not surpass the toilet seat design temperature yet.Therefore, can prevent that the 410T of section that feels to take one's seat is hot when the user is sitting on the 410T of section that takes one's seat.
Then, the moment t3 between through the first temperature raising period behind the D3,600 watts of drivings of control part 210 beginning lamp heaters 480, and D4 continues to carry out 600 watts of drivings of lamp heater 480 between the second temperature raising period.In the case, the take one's seat surface temperature of the 410T of section rises along above-mentioned the second thermograde.
Carry out 600 watts of drivings of lamp heater 480, until the surface temperature of the 410T of section that takes one's seat is a little more than toilet seat design temperature (40 ℃) always.The measurement temperature value of the surface temperature of the 410T of section of taking one's seat when 600 watts of carrying out lamp heater 480 are driven during a little more than the toilet seat design temperature is defined as the target temperature among Figure 10.
The moment t4 of the surface temperature of the 410T of section of taking one's seat during a little more than the toilet seat design temperature is for time of 600 watts of drivings being determined by the heater control table and measure temperature value and reach short period in time of the target temperature of being determined by the heater control table.
Because the second thermograde less than the first thermograde, therefore can prevent from overshoot occurring in the surface temperature variation of toilet seat section 400.
Through the moment t4 behind the second heating-up time D4, the low-power of control part 210 beginning lamp heaters 480 drives, and drives in the low-power that the first maintenance period D5 continues to carry out lamp heater 480.Thereby the surface temperature of the 410T of section that takes one's seat stably maintains the temperature a little more than the toilet seat design temperature.
In this example, the surface temperature of the 410T of section is elevated to the temperature a little more than the toilet seat design temperature of being set by the user owing to take one's seat, and this temperature is maintained to the user and takes one's seat, therefore when the user is sitting in the toilet seat section, feel that sendible temperature is basically identical with the toilet seat design temperature that it is set in advance.
When seating sensor 290 when moment t5 detects the user and is sitting in the toilet seat section 400, control part 210 reduces the current on time that low-power drives, and low-power that continue to carry out lamp heater 480 drives, thus the surface temperature that makes the 410T of section that takes one's seat first take one's seat during D6 drop to the toilet seat design temperature.In this example, first take one's seat during D6 be set as about two minutes.
Moment t6 during taking one's seat through first after the D6, control part 210 further reduces the current on time that low-power drives, and low-power that continue to carry out lamp heater 480 drives, thus the surface temperature that makes the 410T of section that takes one's seat second take one's seat during D7 drop to temperature (36 ℃) a little less than the toilet seat design temperature.In this example, second take one's seat during D7 be set as about two minutes.
Moment t7 during taking one's seat through second after the D7, control part 210 further reduces the current on time that low-power drives, and low-power that continue to carry out lamp heater 480 drives, thereby the surface temperature of the 410T of section that will take one's seat stably maintains temperature (36 ℃) a little less than the toilet seat design temperature at the second maintenance period D8.In the following description, will the second maintenance period D8 keep certain 410T of the section of taking one's seat surface temperature, namely the temperature a little more than the toilet seat design temperature is called holding temperature.
In this example, after the user took toilet seat section 400, control part 210 little by little reduced the surface temperature of the 410T of section that takes one's seat.Thereby can prevent that the user from being burnt by low temperature.
When seating sensor 290 when moment t8 detects the user and leaves toilet seat section 400, control part 210 stops to drive heater 480 in stopping period D9.Therefore, the take one's seat surface temperature of the 410T of section reduces.
Moment t9 when the surface temperature of the 410T of section that takes one's seat reaches 18 ℃, the low-power that control part 210 restarts lamp heater 480 drives, and the low-power of keeping lamp heater 480 during standby in the D10 drives, thereby the surface temperature of the 410T of section that will take one's seat stably maintains 18 ℃.
D4 between the second temperature raising period, control part 210 is carried out 600 watts of drivings of lamp heater 480, but control part 210 can reduce gradually with parabolic path (thick dashed line in the figure of explanation current on time) power of lamp heater 480.
In the case, shown in the thick dashed line in the curve map of the surface temperature of the 410T of section that takes one's seat in explanation, when the surface temperature of the 410T of section that takes one's seat approached temperature a little more than the toilet seat design temperature, thermograde is step-down gradually.
When thermograde becomes when diminishing as described above, can fully reduce the overshoot that the variations in temperature by the 410T of section that takes one's seat causes.
In this example, after the user is sitting in toilet seat section 400, by adjusting the driving power of lamp heater 480, reduce gradually the surface temperature of the 410T of section that takes one's seat, but also can be when the user be sitting in the toilet seat section 400 driving of stopping light heater 480.In the case, can prevent that the user from being burnt by low temperature.
And the surface temperature of the 410T of section that takes one's seat is elevated to the temperature a little more than the toilet seat design temperature, but the surface temperature of the 410T of section that takes one's seat also can be elevated to the toilet seat design temperature.
(9) operation of control part
Figure 17 to Figure 22 is the flow chart of the operation of the control part 210 in the key diagram 3.The operation of control part 210 is described below with reference to accompanying drawings.
At first, the low-power that control part 210 is carried out lamp heater 480 drives, thereby makes the surface temperature of the 410T of section that takes one's seat reach 18 ℃ (step S101).Then, control part 210 judges by the detecting sensor 600 of entering the room whether the user enters toilet (step S102).
When the user did not enter the toilet, control part 210 obtains measured temperature value (step S201), and judged and measure temperature value whether more than the standby temperature (step S202).
When measuring temperature value when the standby temperature is above, the low-power of control part 210 stopping light heaters 480 drives (step S203), and repeating step S201 is to the operation of step S203.And when the measurement temperature value was lower than the standby temperature, control part 210 re-executed step S101.
The operation of step S101, S102 and S201 to S203 (Figure 17) corresponding to above-mentioned standby during the operation of control part 210 of D1 and D10.
At step S102, when the user enters the toilet, control part 210 obtains measures temperature value (step S103), and according to selecting a heater control model (step S104) in the heater control table of this measurement temperature value from be stored in storage part.
Then, control part 210 is judged the 1200 watts of drivings (step S105) that whether have lamp heater 480 in the selected heater control model.And when driving for 1200 watts that do not have lamp heater 480, control part 210 judges whether to exist 600 watts of drivings (step S211) of lamp heater 480.
At step S105, when driving for 1200 watts that have lamp heater 480, control part 210 is opened the timer in these control part 210 timing sections that have own, and carries out 600 watts of drivings of lamp heater 480, to reduce inrush current (step S112).At this moment, control part 210 judged whether through the time (step S113) of being set by selected heater control table.
The operation of the control part 210 during the operation of step S111 to S113 (Figure 18) reduces corresponding to above-mentioned inrush current in the D2.
At step S211, when driving for 600 watts that have lamp heater 480, the operation of control part 210 execution in step S121, this will illustrate below, when driving for 600 watts that do not have lamp heater 480, the operation of control part 210 execution in step S131, this will illustrate below.
At step S113, when passing through the time of setting, control part 210 resets timer, and reopens timer (step S114), and control part 210 is carried out 1200 watts of drivings (step S115) of lamp heaters 480.At this moment, control part 210 judged whether through the time (step S116) of being set by selected heater control table.
When not having through time of setting, control part 210 obtains measures temperature value (step S221), and judges and measure temperature value whether more than inversion temperature (step S222).
When the measurement temperature value is lower than inversion temperature, the operation of control part 210 repeating step S116.
The operation of step S114 to S116, S221 and S222 (Figure 18) is corresponding to the above-mentioned operation of the control part in the D3 210 between the first temperature raising period.

Figure 23 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 2.Figure 24 is the curve map of current on time of the thermal source of the expression embodiment of the invention 2.
As shown in figure 23, toilet seat apparatus comprises: the thermal source that is used for heat toilet seat 2010; Human detection unit 2012; And the control module 2013 that is used for control of heat source and human detection unit.
The below will illustrate operation and the function of this toilet seat apparatus.
Thermal source 2011 is arranged in the toilet seat 2010, by thermal source 2011 heatings, toilet seat 2010 is heated.Human detection unit 2012 detects users whether in the toilet, and the signal of user in the toilet exported to control module 2013.Control module 2013 comprises microcomputer and peripheral circuit, offers the power of thermal source 2011 according to the output signal control of human detection unit 2012.
As shown in figure 24, when detecting human body by human detection unit 2012, control module 2013 provides the power of certain hour to the thermal source 2011 of heat toilet seat 2010 with the first current on time.Supplied with by control module 2013 power ratio controls, so that after the certain hour, make toilet seat 2010 reach in the given time the temperature that can take one's seat with the second current on time higher than the first current on time.Begin to be energized to through after the scheduled time from thermal source 2011, the current on time that maintains design temperature with the temperature with toilet seat 2010 carries out power supply.And, the minimum temperature that can not feel well when the temperature that can take one's seat is sitting in toilet seat 2010 for the user.
Usually, can think, from initial stage that thermal source 2011 begins to switch on the second current on time to thermal source 2011 energisings, so that the temperature of toilet seat 2010 reaches the temperature that can take one's seat as soon as possible.But, as described in the problems referred to above, during owing to thermal source 2011 cooling (temperature is equivalent to the room temperature in the toilet), the resistance of thermal source 2011 is very little, therefore 1/10 of resistance during for its rated watt consumption, have larger inrush current to flow through at the initial stage that begins to switch on.And when using simultaneously other products (particularly having the product that carries heater) in the toilet, then thinking has larger electric current to flow through.Generally speaking, because the power distribution in the toilet is not the distribution of large electric current, but single power distribution, so common RCCB and the overcurrent vreaker that is not provided for tackling large electric current in the toilet.And generally speaking, electric current also is drawn out to lighting device in the toilet from same power distribution.Therefore, when electric heat source 2011 and the heater that is installed in other products in the toilet are switched on simultaneously (for example heating is used for cleaning the water heater of the wash water of body local), because overcurrent disconnects breaker or causes voltage drop because of the resistive element of indoor power distribution.Therefore, following point appearring: offers toilet seat apparatus, is installed in other products in the toilet and the lower voltage of the lighting apparatus in the toilet; Toilet seat apparatus and the properties of product decline that is installed in other products in the toilet; Room lighting brightness descends.
Usually, because the resistance of thermal source 2011 reaches rated resistance at short notice, therefore can suppress rapidly inrush current.Therefore, when beginning to switch on, provide power with the first current on time heat source 2011, then carry out control with the second current on time higher than the first current on time, thereby can suppress large inrush current.Therefore, the voltage drop that disconnects with regard to the breaker that can not occur causing because of overcurrent or cause because of the resistive element of house wire.Therefore, the voltage that offer toilet seat apparatus, is installed in other products in the toilet and the lighting apparatus in the toilet just can not reduce, toilet seat apparatus and the properties of product that are installed in other products in the toilet can not descend, and room lighting brightness can not descend yet.Therefore, can provide a kind of easy to use and be rich in the toilet seat apparatus of energy saving.
And, because thermal source is switched to the toilet seat temperature is maintained the required minimum power of temperature that can take one's seat, can switch on to thermal source necessarily, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.

Figure 25 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 3.
As shown in figure 25, this toilet seat apparatus has the detection unit at room temperature 2014 for detection of room temperature, and control module 2013 is according to the scheduled time of being determined heat source 2011 energisings by detection unit at room temperature 2014 detected room temperatures.
Figure 26 is the curve map of the toilet seat variations in temperature of the explanation embodiment of the invention 3.
As shown in figure 26, in room temperature under the higher and low both of these case, the temperature of the toilet seat 2010 before owing to detecting human body thermal source 2011 begun to switch on is different, therefore after thermal source 2011 begins to switch on to the time that the temperature of toilet seat 2010 reaches till the temperature that can take one's seat also be different.For example, when room temperature was low, the temperature of toilet seat 2010 was also lower, and the programming rate of toilet seat 2010 is also slower.Therefore, must give for a long time thermal source 2011 energisings, so that the temperature of toilet seat 2010 reaches the temperature that can take one's seat.But in the higher situation of room temperature, during to identical time of thermal source 2011 energising, the temperature of toilet seat 2010 has just surpassed the temperature that can take one's seat.On the contrary, when room temperature was higher, the temperature of toilet seat 2010 was also higher, and the programming rate of toilet seat 2010 is also very fast.Therefore, only need in short time thermal source 2011 to be switched on, can make the temperature of toilet seat 2010 reach the temperature that to take one's seat.But in the lower situation of room temperature, during to identical time of thermal source 2011 energising, the temperature of toilet seat 2010 does not just reach the temperature that can take one's seat.
Therefore, control module 2013 is according to definite scheduled time to thermal source 2011 energisings of room temperature.Therefore, the temperature of toilet seat 2010 can reach the temperature that can take one's seat within the shortest time of necessity, thereby a kind of toilet seat apparatus easy to use can be provided.And, owing to thermal source 2011 is not carried out unnecessary energising, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.

Figure 27 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 4.
As shown in figure 27, toilet seat 2010 has the toilet seat temperature detecting unit 2015 for detection of the toilet seat temperature, and control module 2013 is according to the scheduled time of being determined by toilet seat temperature detecting unit 2015 detected toilet seat temperature thermal source 2015 energisings.
Usually, in case 2011 pairs of toilet seats 2010 of thermal source heat, when after the user uses, stopping the power supply to thermal source 2011, need the regular hour just can make the drop in temperature of toilet seat 2010.When reality is used, use the time interval of toilet seat apparatus different because environment, environment for use and time period etc. are set.For example, in of family of four, in order to go to school and to work, toilet seat apparatus was used continuously in this same time period the time period in the morning.And when toilet seat apparatus was installed in the frequent public utility of coming in and going out of people etc., toilet seat apparatus was used continuously.In these occasions, because the use interval of toilet seat is very short, therefore when the temperature of toilet seat 2010 is also very high, just begin thermal source 2011 energisings.Even in such occasion, when the scheduled time to thermal source 2011 energisings is set as the identical time, carry out unnecessary energising, cause unnecessary power consumption.
Therefore, control module 2013 is according to definite scheduled time to thermal source 2011 energisings of the temperature of toilet seat 2010.Therefore, the temperature of toilet seat 2010 can reach the temperature that can take one's seat within the shortest time of necessity, thereby a kind of toilet seat apparatus easy to use can be provided.And, owing to thermal source 2011 is not carried out unnecessary energising, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.
In this embodiment, toilet seat temperature detecting unit 2015 is installed in the toilet seat, but the present invention is not limited to this, as long as be located on toilet seat surface element etc. and the closely-related position of the surface temperature of toilet seat, can obtain identical effect.

Figure 28 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 5.Figure 29 is the curve map of current on time of the thermal source 3011 of the expression embodiment of the invention 5.
As shown in figure 28, this toilet seat apparatus comprises thermal source 3011, is used for heat toilet seat 3010; Human detection unit 3012 is for detection of human body; Be used for control and detect the detecting unit 3013 of taking one's seat that the user takes one's seat; And control module 3014, be used for above-mentioned control of heat source 3011, human detection unit 3012 and the detecting unit 3013 of taking one's seat.
The below will illustrate operation and the function of the toilet seat apparatus of said structure.
Thermal source 3011 is arranged in the toilet seat 3010, by thermal source 3011 heatings toilet seat 3010 is heated.Human detection unit 3012 detects users whether in the toilet, and with the user whether the signal in the toilet export to control module 3014.Whether human detection unit 3013 detects the user and is sitting on the toilet seat apparatus, and the state of the user being taken one's seat/not taking one's seat is exported to control module 3014 as signal.Control module 3014 comprises microcomputer and peripheral circuit, supplies with the power of thermal source 3011 according to the output signal control of human detection unit 3012 and the detecting unit 301 3 of taking one's seat.
As shown in figure 29, when detecting human body by human detection unit 3012, control module 3014 is supplied with the power of certain hour to the thermal source 3014 that is used for heat toilet seat 3010 with the first current on time.Supplied with by control module 3014 power ratio controls, after this certain hour, make toilet seat 3010 reach in the given time the temperature that can take one's seat with the second current on time higher than the first current on time.And when the detecting unit 3013 of taking one's seat detected human body and is sitting on the toilet seat 3010, the current on time of control module 3014 control of heat sources 3014 was three current on time lower than the second current on time.Thermal source 3011 is energized to through after the scheduled time from beginning, the current on time that maintains predetermined temperature with the temperature with toilet seat 3010 carries out power supply.And, the minimum temperature that the temperature that can take one's seat can not feel well when being sitting on the toilet seat 3010 for the user.
Usually, can think, from initial stage that thermal source 3011 begins to switch on the second current on time to thermal source 3011 energisings, so that the temperature of toilet seat 3010 reaches the temperature that can take one's seat as soon as possible.But, as described in the problems referred to above, because when thermal source 3011 cooling (temperature is equivalent to the room temperature in the toilet), the resistance of thermal source 3011 is very little, 1/10 of resistance during for its rated watt consumption, therefore, at the initial stage that thermal source 3011 begins to switch on, there is larger inrush current to flow through.And when using simultaneously other products (particularly being equipped with the product of heater) in the toilet, then thinking has larger electric current to flow through.Generally speaking, owing to be not the distribution of large electric current for the power distribution in the toilet, but single power distribution, so common RCCB and the overcurrent vreaker that is not provided for the tackling large electric current toilet in.And usually electric current also is drawn out to lighting device in the toilet from same power distribution.Therefore, when thermal source 3011 and the heater that is installed in other products in the toilet are switched on simultaneously (for example, the water heater that is used for the wash water of heated wash body local), because of overcurrent breaker is disconnected or cause voltage drop because of the resistive element of indoor power distribution.Therefore, following point appearring: offers toilet seat apparatus, is installed in other products in the toilet and the lower voltage of the lighting apparatus in the toilet; Toilet seat apparatus and the properties of product decline that is installed in other products in the toilet; Room lighting brightness descends.
Usually, because the resistance of thermal source 3011 reaches rated resistance at short notice, therefore can suppress rapidly inrush current.Therefore, when beginning to switch on, provide power with the first current on time heat source 3011, then control with the second current on time higher than the first current on time, thereby can suppress large inrush current.Therefore, the voltage drop that disconnects with regard to the breaker that can not occur causing because of overcurrent or cause because of the resistive element of house wire.Therefore, the voltage that offer toilet seat apparatus, is installed in other products in the toilet and the lighting apparatus in the toilet just can not reduce, toilet seat apparatus and the properties of product that are installed in other products in the toilet can not descend, and room lighting brightness can not descend yet.Therefore, can provide a kind of easy to use and be rich in the toilet seat apparatus of energy saving.
And because when human body was sitting on the toilet seat 3010 and be not sitting on the toilet seat 3010, the surface state of toilet seat 3010 was different, so toilet seat 3010 produces temperature difference.And because when human body is sitting on the toilet seat, toilet seat 3010 is covered by human body, therefore heat-insulating property improves, and because body temperature has heated toilet seat, therefore compare with the state that human body is not sitting on the toilet seat 3010, the surface temperature of toilet seat 3010 is higher.
In control module 3014, when the detecting unit 3013 of taking one's seat detects the user and takes one's seat, provide power with the 3rd current on time heat source 3011 lower than the second current on time, thereby can suppress useless power.Therefore, can provide a kind of easy to use and be rich in the toilet seat apparatus of energy saving.

As shown in figure 34, control module 4013 when detecting human body by human detection unit 4012, rises a plurality of current on time ladders ground and the thermal source 4011 that is used for heat toilet seat 4010 is carried out the power supply of certain hour.Supplied with by control module 4013 power ratio controls, after certain hour, make toilet seat 4010 reach in the given time the temperature that can take one's seat with certain current on time higher than above-mentioned a plurality of current on times.Begin to be energized to through after the scheduled time from thermal source 4011, the current on time that maintains design temperature with the temperature with toilet seat 4010 is carried out the power supply operation.And, the minimum temperature that the temperature that can take one's seat can not feel well when being sitting on the toilet seat 4010 for the user.
Usually, can think, with higher certain current on time thermal source 4011 be switched on from the initial stage that begins to switch on, so that the temperature of toilet seat 4010 reaches the temperature that can take one's seat as soon as possible.But, as described in the problems referred to above, because when thermal source 4011 cooling (temperature is equivalent to the room temperature in the toilet), the resistance of thermal source 4011 is very little, therefore 1/10 of resistance during for its rated watt consumption, have larger inrush current to flow through at the initial stage that begins to switch on.And when using simultaneously other products (particularly being equipped with the product of heater) in the toilet, then thinking has larger electric current to flow through.Generally speaking, owing to be not the distribution of large electric current for the power distribution in the toilet, but single power distribution, so common RCCB and the overcurrent vreaker that is not provided for the tackling large electric current toilet in.And usually electric current also is drawn out to lighting device in the toilet from same power distribution.Therefore, when thermal source 4011 and the heater that is installed in other products in the toilet are switched on simultaneously (water heater that for example is used for the wash water of heated wash body local), because overcurrent disconnects breaker or causes voltage drop because of the resistive element of indoor power distribution.Therefore, following point appearring: offers toilet seat apparatus, is installed in other products in the toilet and the lower voltage of the lighting apparatus in the toilet; Toilet seat apparatus and the properties of product decline that is installed in other products in the toilet; Room lighting brightness descends.
Usually, because the resistance of thermal source 4011 reaches rated resistance at short notice, therefore can suppress rapidly inrush current.Therefore, when beginning to switch on, provide power with a plurality of current on time heat source 4011, then control with certain current on time higher than a plurality of current on times, thereby can suppress large inrush current.Therefore, the voltage drop that disconnects with regard to the breaker that can not occur causing because of overcurrent or cause because of the resistive element of house wire.Therefore, the voltage that offer toilet seat apparatus, is installed in other products in the toilet and the lighting apparatus in the toilet just can not reduce, toilet seat apparatus and the properties of product that are installed in other products in the toilet can not descend, and room lighting brightness can not descend yet.Therefore, can provide a kind of easy to use and be rich in the toilet seat apparatus of energy saving.
And, the toilet seat temperature is maintained the required minimum power of temperature that can take one's seat namely be incubated current on time owing to switch to, and can not carry out unnecessary energising to thermal source, therefore can realize a kind of more energy-conservation toilet seat apparatus.
In this embodiment, the control of when a plurality of current on time ladders ground is risen, switching on, but the present invention is not limited to this, also can temporarily reduce current on time in the process that current on time rises, or prolong the time of switching on certain current on time.By carrying out above control operation, can prevent that toilet seat is overheated.
(embodiment 9)
Figure 35 is the figure of current on time of the thermal source 4011 of the expression embodiment of the invention 9.
The difference of this embodiment and embodiment 8 is, as shown in figure 35, when human detection unit 4012 detects human body, control module 4013, when improving the power supply current on time of the thermal source 4011 that is used for heat toilet seat 4010 continuously, carry out the power supply of certain hour.Control module 4013 power ratio controls are supplied with, and after certain hour, make toilet seat 4010 reach in the given time the temperature that can take one's seat with certain current on time higher than the current on time of this continuous raising.
As mentioned above, because when thermal source 4011 cooling (temperature is equivalent to the room temperature in the toilet), the resistance of thermal source 4011 is very little, 1/10 of the resistance during for its rated watt consumption, therefore, there is larger inrush current to flow through at the initial stage that thermal source 4011 begins to switch on.But when to thermal source 4011 energising, because thermal source 4011 heatings, the temperature of thermal source 4011 itself also rise, so the resistance value of thermal source 4011 increases gradually, thereby along with the resistance variations of thermal source 4011 has also suppressed inrush current.
Therefore, when human detection unit 4012 detected human body, control module 4013 increased the current on time to the power supply of thermal source 4011 that is used for heat toilet seat 4010 continuously.Therefore, the temperature of toilet seat 4010 can reach the temperature that can take one's seat within the shortest time of necessity, thereby a kind of toilet seat apparatus easy to use can be provided.And, owing to thermal source 4011 is not carried out unnecessary energising, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.
(embodiment 10)
Figure 36 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 10.Figure 37 is the curve map of the toilet seat variations in temperature of the expression embodiment of the invention 10.
As shown in figure 36, this toilet seat apparatus has the detection unit at room temperature 4014 for detection of room temperature, and control module 4013 is according to the scheduled time of being determined by detection unit at room temperature 4015 detected room temperatures thermal source 4011 energisings.
As shown in figure 37, in room temperature under the higher and low both of these case, owing to beginning the temperature of the toilet seat 4011 before thermal source 4010 energising different detecting human body, therefore, begin to switch on from thermal source 4010 after to the time that the temperature of toilet seat 4011 reaches the temperature that can take one's seat also be different.For example, when room temperature was low, the temperature of toilet seat 4010 was also lower, and the programming rate of toilet seat 4010 is also slower.Therefore, must be for a long time to thermal source 4011 energisings, so that the temperature of toilet seat 4010 reaches the temperature that can take one's seat.But when in the higher situation of room temperature, if to the thermal source identical time of 4011 energisings, then the temperature of toilet seat 4010 has just surpassed the temperature that can take one's seat.On the contrary, when room temperature was higher, the temperature of toilet seat 4010 was also higher, and the programming rate of toilet seat 4010 is also very fast.Therefore, only need in short time thermal source 4011 to be switched on, can make the temperature of toilet seat 4010 reach the temperature that to take one's seat.But in the lower situation of room temperature, if to the thermal source identical time of 4011 energisings, then the temperature of toilet seat 4010 does not reach the temperature that can take one's seat.
Therefore, control module 4013 is according to definite scheduled time to thermal source 4011 energisings of room temperature.Therefore, the temperature of toilet seat 4010 can reach the temperature that can take one's seat within the shortest time of necessity, thereby a kind of toilet seat apparatus easy to use can be provided.And, owing to thermal source 4011 is not carried out unnecessary energising, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.

Figure 38 is the block diagram of the toilet seat apparatus of the explanation embodiment of the invention 11.
As shown in figure 38, this toilet seat apparatus has the toilet seat temperature detecting unit 4015 for detection of the temperature of toilet seat 4010, and control module 4013 is determined scheduled time to thermal source 4011 energising according to toilet seat temperature detecting unit 4015 detected toilet seat temperature.
Usually, in case 4011 pairs of toilet seats of thermal source 4010 heating when then stopping the power supply to thermal source 4010 after the user uses, needs the regular hour just can make the drop in temperature of toilet seat 4011.When reality is used, use the time interval of toilet seat apparatus different because environment, environment for use and time period etc. are set.For example, in of family of four, in order to go to school and to work, toilet seat apparatus was used continuously in this same time period the time period in the morning.And when toilet seat apparatus was installed in the frequent public utility of coming in and going out of people etc., toilet seat apparatus was used continuously.In these occasions, because the use interval of toilet seat is very short, therefore when the temperature of toilet seat 4011 is also very high, just thermal source 4010 is switched on.Similarly, in such occasion, if will be set as the identical time to the scheduled time of thermal source 4011 energisings, then can carry out unnecessary energising, thereby cause unnecessary power consumption.
Therefore, control module 4013 is according to definite scheduled time to thermal source 4011 energisings of the temperature of toilet seat 4010.Therefore, the temperature of toilet seat 4010 can reach the temperature that can take one's seat within the shortest time of necessity, thereby a kind of toilet seat apparatus easy to use can be provided.And, owing to thermal source 4011 is not carried out unnecessary energising, therefore can realize a kind of toilet seat apparatus that is rich in energy saving.
In this embodiment, toilet seat temperature detecting unit 4015 is installed in the toilet seat, but the present invention is not limited to this, as long as on the surface element etc. that is located at toilet seat and the closely-related position of the surface temperature of toilet seat, can obtain identical effect.
According to specific embodiment the present invention is had been described in detail, but those skilled in the art will envision that, in situation without departing from the spirit and scope of the present invention, can carry out various modifications and changes.
