Sidepiece in main body 21 is provided with infrared ray sensor portion 24, receives the infrared signal from remote controller (not shown) and body detecting part's (purpose of taking a seat detecting unit) 25.Body detecting part 25 for example is made of thermoelectric pickup and infrared luminous part, when having human body in detecting toilet space, sends infrared signal (purpose of taking a seat detection signal).This infrared signal can be considered the expression user and has the signal that is seated at the purpose on the toilet seat 22 and enters the toilet, therefore, can desire to be seated at the purpose on the toilet seat 22 with higher chance detection user.
And, be provided with notice LED 280 at the upper surface of main body 21.This notice LED 280 is notification units of the soaking condition of notice toilet seat 22, just begun to heat up from toilet seat, this notice LED 280 begins flicker, even and be warmed up under the situation about being seated at more than the temperature that also can not feel cold on the toilet seat 22, this notice LED 280 lights constantly, notifies the soaking condition of toilet seat 22 to the user.
As Fig. 2, shown in Figure 3, toilet seat 22 is following structure: respectively in inner peripheral and outer peripheral edges by welding manner with plastic 2 components bonding up and down, thereby form housing 26, portion has the airtight cavity portion 27 that can stop water etc. to be invaded within it.
Inside in above-mentioned cavity portion 27, in the mode relative with the portion of taking a seat of toilet seat 22, be provided with to aluminium sheet carry out after the mirror finish radiation reflecting plate 28 and as the lamp heater 29 of radial pattern heater.The end of radiation reflecting plate 28 has the kink of bending upward along complete cycle, by this kink the heat radiation from lamp heater 29 is turned to, so, help to improve the outer peripheral edges portion that separates with lamp heater 29 and the radiation density of inner peripheral portion, realize homogenising towards the radiation profiles on housing 26 tops.Near this lamp heater 29, be provided with the thermostat 30 (thermostat) and the temperature fuse 31 that in series are electrically connected with lamp heater 29, play at the dangerous state of affairs that in a single day takes place and prevent the effect that excessive temperature rises.
Above-mentioned lamp heater 29 constitutes, the internal run-through of glass tube 32 be provided with the filament 33 that constitutes by tungsten and enclosed halogen gas 34, carry out forming the halogen circular response of tungsten halide repeatedly, thus, play the effect of the consumption that prevents filament 33 along with the heating of filament 33.By this effect, filament 33 that can thermal capacity is very little can make emittance rise extremely sharp as thermal source.This lamp heater 29 is fixed on the radiation reflecting plate 28 by the lamp heater fixture 36 that has as the rubber bushing 35 of elastic component, and radiation reflecting plate 28 is fixed on the housing 26 by rubber feet 37.In the rubber pillar 39 of toilet seat 22, be provided with the detecting unit 38 of taking a seat that constitutes by microswitch 40, make switch connection, detect taking a seat of user thus in response to the heavy burden on the toilet seat 22 increases.
As shown in Figure 4, about housing 26, upper surface in the housing body 41 of using the transparent polypropylene resin material, constituting by injection moulding, formation contains the radiant heat absorbed layer 42 of a large amount of carbon blacks, further on this radiant heat absorbed layer 42, formed surface decoration layer 43 as light shield layer, it covers from whole visible light of lamp heater 29 radiation, and has considered case hardness, drug-resistant performance, glossiness etc.About housing body 41, carry out the shaping of transparent polypropylene resin material with average thickness 2.5mm, thus, the radiant heat transmissivity is set at more than 70%, simultaneously, utilize its rigidity and bring into play the effect of the structure support body of toilet seat.And, the thickness of formed radiant heat absorbed layer 42 is 0.1mm, the thickness of surface decoration layer 43 is 0.2mm, this two-layer radiant heat that sees through housing body 41 that absorbed fully, because their thermal capacity is very little, so when temperature moment rising, can meanwhile block the visible light that radiates fully.
In the recess on the inner surface that is arranged at housing 26, embedding has thermistor 44, this thermistor 44 to contact with radiant heat absorbed layer 42 and becomes the temperature roughly the same with it, so, can directly detect the temperature of radiant heat absorbed layer 42.And, being provided with the turning cylinder 45 that extends along left and right directions at the rear portion of toilet seat 22, toilet seat 22 can be that basic point swings up and down between state of erecting and horizontal user mode with this turning cylinder 45.On this turning cylinder 45, be formed with electrode 46, constitute toilet seat position detection unit 47, detect toilet seat and be in the state of erecting or be in the use location of putting down the approximate horizontal of using with the bearing portion (not shown) of main body 21.On main body 21, be provided with room temperature detecting sensor 48 and control part 50 as the sensor that is used to detect room temperature, this control part 50 has timing portion 49,49 pairs in this timing portion from begin to heat up because of switching on to the lamp heater 29 of toilet seat 22 the time elapsed time of lighting count.And, signal from body detecting part 25, the detecting unit 38 of taking a seat, thermistor 44, toilet seat position detection unit 47 and room temperature detecting sensor 48 is passed to control part 50 respectively, control part 50 is according to the energising of these signal controlling at lamp heater 29, makes that the temperature as the upper surface of the toilet seat 22 of heating face becomes set point of temperature.
And, as shown in Figure 2, in the toilet, being provided with the warm portion 52 of indoor system, the warm portion 52 of this indoor system has warm heater 53 of indoor system and indoor system warm braw fan 54, and the system of carrying out in the toilet is warm.
According to said structure, entered the user under the situation of toilet, body detecting part 25 detects this situation, and its signal is sent to control part 50 via infrared ray sensor portion 24.At this moment, when the signal according to toilet seat position detection unit 47 confirmed toilet seat 22 and is positioned at the use location of approximate horizontal, control part 50 began lamp heater 29 is switched on.After beginning energising, via glass tube 32 and the radiation reflecting plate 28 direction irradiates light to housing body 41, light moment radiates away as emittance from filament 33.Then, though emittance be partially absorbed in the inside of housing body 41 or reflect, but more than half part of emittance is transmitted into housing body 41 and contributes to the intensification of radiant heat absorbed layer 42 and surface decoration layer 43.As mentioned above, almost can moment ground the heating face of the portion of taking a seat of toilet seat 22 is heated, so, need not switch on to heater all the time, very energy-conservation.
In addition, in the present embodiment, used lamp heater 29 as the heater that the portion of taking a seat of toilet seat 22 is heated, but, heater is not limited to lamp heater 29, for example also can constitute, and the wire heater that has used enamel-covered wire is sticked on the back side of the portion of taking a seat of toilet seat 22.The fine heat-resisting performance of enamel-covered wire can make toilet seat 22 heat up in the fully short time, and, can guarantee electrical insulating property and security.
＜2〉power-up sequence of seat device
Roughly drive the power of lamp heater 29, carry out the driving control of lamp heater 29 thus by 3 phasic changes.
For example, under the situation that toilet seat 22 is heated up with the 1st thermograde, control part 50 drives (1200W driving) with the power of about 1200W to lamp heater 29.
If establishing the resistance value of lamp heater 29 is 8.33 Ω,, produce (the power of ÷ 8.33 Ω=1200W of 100V * 100V) then when lamp heater 29 being applied when exchanging 100V.That is, in the whole cycle of AC power, in lamp heater 29, flow through electric current, thus, produce the power of 1200W.
In addition, under the situation that toilet seat 22 is heated up with the 2nd thermograde slightly more slow than the 1st thermograde, control part 50 drives (600W driving) with the power of about 600W to lamp heater 29.
In addition, under the temperature that makes toilet seat 22 kept constant situation, control part 50 drove (low-power driving) with the power of about 50W to lamp heater 29.Here, so-called low-power drives, and is meant that utilization drives lamp heater 29 far below the power (for example power in the scope of 0W～50W) that 1200W drives and 600W drives.
By by the current on time commutation circuit of control part 50 to controlling to the energising of lamp heater 29 from control part 50, carry out the switching that 1200W drives, 600W drives and low-power drives thus.
Never illustrated power circuit provides alternating current to control part 50.Therefore, control part 50 makes the alternating current that is provided flow through lamp heater 29 according to the energising control signal that provides from the current on time commutation circuit.
Fig. 5 is the figure of variation that the surface temperature of the driving example of lamp heater 29 and toilet seat 22 is shown.In Fig. 5, the current on time when showing the curve map of expression surface temperature of toilet seat 22 and the relation between the time and expression lamp heater 29 being driven and the curve map of the relation between the time.The transverse axis of these 2 curve maps is common time shaft.
In the present embodiment, be assumed to be following situation: the user connects the system heating function in advance, sets the toilet seat design temperature higher (38 ℃).
Wait in the winter time, room temperature is lower than the standby temperature promptly under 18 ℃ the situation, control part 50 carries out adjustment, makes the temperature of toilet seat 22 become 18 ℃.Like this, among the D1, the low-power that control part 50 carries out lamp heater 29 drives during the standby before in body detecting part 25 detects user's inlet chamber, makes 8 ℃ of the surface temperature stuck-at-s of toilet seat 22.During the low-power of D1 drives during this standby, according to the energising of temperature change in the toilet to lamp heater 29, realize the reduction of power consumption thus, this will narrate in the back.
Detect the user in body detecting part 25 in moment t1 and enter under the indoor situation, control part 50 carries out 600W and drives among the D2 during inrush current reduces.Need to prove that this 600W drives in order fully to reduce inrush current and carries out.About lamp heater 29,, then will produce bigger inrush current if filament 33 is colder before the energising.Even the overcurrent that produce this moment is momentary, still can apply load to heater and circuit, thereby the life-span is caused harmful effect,, can cause cost to rise like this though can use the electronic unit that has a tolerance for overcurrent to carry out circuit design.And in the present embodiment, at first, in order to suppress inrush current, the electric weight that only feeds half is to suppress to occur influence.In this case, the surface temperature of toilet seat 22 rises with the 2nd slightly slow thermograde.
Need to prove,, be not limited thereto though the time point that here body detecting part 25 is detected in user's inlet chamber is made as t1 constantly.For example, the unit that the switching of the door that opens and closes in the time of also can being provided with the turnover toilet detects thus, is set at t1 constantly with detecting the time point that opens the door.Like this, detecting under the situation of opening the door, also same with the situation of utilizing body detecting part 25, the user can be detected and purpose on the toilet seat 22 will be seated at, so, by this time point being made as t1 constantly, can make toilet seat 22 be warmed up to appropriate temperature in advance.In addition, as the unit of the purpose of taking a seat that detects the user in advance, can also adopt the unit that detects the action (action of opening upward) open toilet cover 23, detect the unit that makes the action that toilet seat 22 swings downwards etc.
Then, passed through inrush current reduce during moment t2 behind the D2, the 1200W of control part 50 beginning lamp heaters 29 drives, between the 1st temperature raising period D3 during in, the 1200W that continues to carry out lamp heater 29 drives.In this case, the surface temperature of toilet seat 22 rises with above-mentioned the 1st thermograde.
At this moment, the surface temperature of toilet seat 22 rises hastily.The 1200W of lamp heater 29 drives the surface temperature that is performed until toilet seat 22 and reaches set point of temperature (hereinafter referred to as " using the initial target temperature ", for example being 30 ℃).Certainly, the warm temperature of this set point of temperature (using the initial target temperature) system of can being set to, but, this set point of temperature also can not be the temperature that fully rises to the warm temperature of system, promptly, can be than the warm low temperature of temperature of system, as long as do not feel more than the minimum critical-temperature (creeping chill critical-temperature) of the unplessantness displeasure that cold is such for not allowing the user when taking a seat, produce.According to examinee's experiment that the inventor implemented, this critical-temperature is approximately 29 ℃ as can be known.Promptly, as using the initial target temperature, so long as than standby temperature height and be in the temperature that the hypothesis user is seated in the temperature range of taking a seat (for example being approximately 29～38 ℃) on the toilet seat 22 and get final product,, can adopt above-mentioned creeping chill critical-temperature (about 29 ℃) as its lower limit.
Like this, between the 1st temperature raising period, among the D3, make the surface temperature of toilet seat 22 rise to set point of temperature rapidly by the 1200W driving.Can not feel toilet seat 22 colds when thus, the user is on being seated at toilet seat 22.
Here, the use initial target temperature of the surface temperature of toilet seat 22 and the intensification ability of lamp heater 29 determine above-mentioned standby temperature (for example 18 ℃) when finishing as D3 between the 1st temperature raising period.That is, during having made up inrush current and having reduced between D2 and the 1st temperature raising period D3 during in, considered the intensification ability of lamp heater 29, thus, the standby temperature can be set at and can reach the minimum temperature of using the initial target temperature.Thus,, realized guaranteeing the surface temperature of the toilet seat 22 of the comfortableness the when user takes a seat as using the initial target temperature, and, during standby among the D1 as far as possible the lowland set the standby temperature, thus, reduced the power consumption that is used to keep the standby temperature.
In addition, in the present embodiment, as the intensification ability of this lamp heater 29, can adopt the surface temperature that can make toilet seat 22 with 0.5～5 open/second the specification that heats up of speed.Perhaps, be preferably such specification: from the purpose of taking a seat that detects the user to actual be seated on the toilet seat 22 during, can heat up about 3～25 ℃.And then, according to inventor's experiment as can be known, for example for the individual residence of Japan, on average need about 6 seconds to undressing and being seated on the toilet seat 22 from the door of opening the toilet.Therefore, preferably, have and can be in these about 6 seconds reach the specification of using the initial target temperature from the standby temperature, in this case, preferred programming rate is at least and 1.7 opens/second more than, more preferably 2 open/second more than.
And, get final product so long as have the heater of this intensification ability, and be not limited to lamp heater 29, also can adopt following structure: will not use photothermal flake heater, tubular heater, face heater stick on the back side of the face of taking a seat such, other the structure that the portion of taking a seat is heated; And for example heater is embedded into structure in the toilet seat parts etc.
And, when the surface temperature that as above makes toilet seat 22 rises rapidly, in its variations in temperature, will produce overshoot (overshoot).But, in the present embodiment, when the surface temperature of toilet seat 22 reaches set point of temperature, the 1200W of lamp heater 29 driven switch to 600W and drive.Therefore, even taken place under the situation of overshoot in the variation of the surface temperature of toilet seat 22, its surface temperature can not surpass the toilet seat design temperature yet.Its result has prevented that the user from feeling the situation that toilet seat 22 scalds when taking a seat.
Then, passing through the moment t3 behind the D3 between the 1st temperature raising period, the 600W of control part 50 beginning lamp heaters 29 drives, and among the D4, continues to carry out the 600W driving of lamp heater 29 between the 2nd temperature raising period.In this case, the surface temperature of toilet seat 22 rises with above-mentioned the 2nd thermograde.The 600W of lamp heater 29 drives the surface temperature that is performed until toilet seat 22 and reaches toilet seat design temperature (38 ℃).
The 2nd thermograde is slightly more slow than the 1st thermograde.Thus, prevented from the variation of the surface temperature of toilet seat 22, to produce bigger overshoot.
Passing through the moment t4 behind the D4 between the 2nd temperature raising period, the low-power of control part 50 beginning lamp heaters 29 drives, and among the D5, continues to carry out the low-power driving of lamp heater 29 during the 1st keeps.Thus, the surface temperature of toilet seat 22 is fixed on the toilet seat design temperature.
Detecting the user at the detecting unit 40 of taking a seat in moment t5 is seated under the situation on the toilet seat 22, control part 50 reduces the current on time that low-power drives, among the D6, the low-power of proceeding lamp heater 29 drives, and makes the surface temperature of toilet seat 22 keep the toilet seat design temperature during the 1st takes a seat.In the present embodiment, the 1st take a seat during D6 be set to about 10 minutes.
And, passed through the 1st take a seat during moment t6 behind the D6, control part 50 further reduces the current on time that low-power drives, during the 2nd takes a seat among the D7, the low-power of proceeding lamp heater 29 drives, and makes the surface temperature of toilet seat 22 be reduced to the temperature more lower slightly than toilet seat design temperature (36 ℃).In the present embodiment, the 2nd take a seat during D7 be set to about 2 minutes.
Passed through the 2nd take a seat during moment t7 behind the D7, control part 50 further reduces the current on time that low-power drives, in the D8, the low-power of proceeding lamp heater 29 drives, and makes the surface temperature of toilet seat 22 be fixed on the temperature more lower slightly than toilet seat design temperature (36 ℃) during the 2nd keeps.In the following description, surface temperature, promptly lower slightly than the toilet seat design temperature temperature of keeping the toilet seat 22 during constant during keeping the 2nd among the D8 is called holding temperature.
Like this, in the present embodiment, after the user was seated on the toilet seat 22, control part 50 reduced the surface temperature of toilet seat 22 gradually.Thus, prevented that the user from low temperature taking place burn.
When taking a seat detecting unit 40 when moment t8 detects the user and leaves toilet seat 22, the driving of control part 50 stopping light heater 29 in stopping period D9.Thus, the surface temperature of toilet seat 22 reduces.
Reach 18 ℃ moment t9 in the surface temperature of toilet seat 22, the low-power that control part 50 begins lamp heater 29 once more drives, and among the D10, the low-power of keeping lamp heater 29 drives during standby, makes 8 ℃ of the surface temperature stuck-at-s of toilet seat 22.In addition, same during the low-power of D10 drives during this standby with D1 during the standby, change energising according to temperature in the toilet at lamp heater 29, realize the reduction of power consumption thus, this will narrate in the back.
Like this, under the situation that thermograde becomes mild gradually, can fully reduce the overshoot that the variations in temperature because of toilet seat 22 produces.
In the present embodiment, after the user is seated on the toilet seat 22, the power that is used to drive lamp heater 29 is regulated, thus, the surface temperature of toilet seat 22 is reduced gradually, but, also can be when the user be seated on the toilet seat 22, the driving of stopping light heater 29.In this case, can prevent that also the user from low temperature taking place burn.
As mentioned above, in the present embodiment, following situation is illustrated: leave toilet seat 22 these situations, the driving of stopping light heater 29 in response to detect the user at moment t8.But, also can be from detecting moment t8 that the user leaves toilet seat 22 afterwards, the driving of stopping light heater 29 through certain hour (for example 1 minute).In this case, after once leaving toilet seat 22, the user feels just meaning once more and when being seated on the toilet seat 22 once more, the surface temperature of toilet seat 22 can not reduce yet.Thus, the user can cosily be seated on the toilet seat 22.
When illustrating in combination that with the energising control signal of current on time commutation circuit 1200W drives, when 600W drives and low-power when driving at the "on" position of toilet seat 22.
In the following description, so-called current on time is meant that the time of flowing through alternating current in toilet seat 22 (more precisely the lamp heater 29) accounts for the ratio of the one-period of alternating current.Therefore, mean at the power of lamp heater 29 energisings at the current on time height of lamp heater 29 big, on the contrary, current on time is low means at the power of lamp heater 29 energisings little.
Fig. 6 (a) flows through the oscillogram of the electric current of toilet seat 22 (more precisely the lamp heater 29) when being the 1200W driving, offer the oscillogram of the energising control signal of control part 50 when Fig. 6 (b) is the 1200W driving from the current on time commutation circuit.
Shown in Fig. 6 (b), the energising control signal when 1200W drives is always logical one.When the energising control signal was logical one, control part 50 made the alternating current that provides from power circuit flow through toilet seat 22 (the thick line portion of Fig. 6 (a)).Thus, all there is alternating current to flow through toilet seat 22 in during the whole cycle.Its result is with the power drive toilet seat 22 of about 1200W.
Fig. 7 (a) flows through the oscillogram of the electric current of toilet seat 22 when being the 600W driving, offer the oscillogram of the energising control signal of control part 50 when Fig. 7 (b) is the 600W driving from the current on time commutation circuit.
Shown in Fig. 7 (b), the energising control signal when 600W drives is made of the pulse with the alternating current same period that offers control part 50.Duty of ratio (logic accounts for the ratio of pulse period for the pulsewidth of " 1 ") is set to 50%.
When the energising control signal was logical one, control part 50 made the alternating current that provides from power circuit flow through toilet seat 22 (the thick line portion of Fig. 7 (a)).Thus, there is alternating current to flow through toilet seat 22 in during half period.Its result is with the power drive toilet seat 22 of about 600W.
Fig. 8 (a) flows through the oscillogram of the electric current of toilet seat 22 when being the low-power driving, offer the oscillogram of the energising control signal of control part 50 when Fig. 8 (b) is the low-power driving from the current on time commutation circuit.
Shown in Fig. 8 (b), the energising control signal when low-power drives is made of the pulse with the alternating current same period that offers control part 50.Duty of ratio is set to less than 50% (about for example several percentages).
When the energising control signal was logical one, control part 50 made the alternating current that provides from power circuit flow through toilet seat 22 (the thick line portion of Fig. 8 (a)).In each cycle, be equivalent to pulsewidth during have alternating current to flow through toilet seat 22.Its result is for example with the power drive toilet seat 22 of about 50W.
In addition, in the temperature that reduces toilet seat 22 or to cut off the situation of system heating function of seat device 110 inferior, the current on time commutation circuit does not provide energising control signal (control signal of will switching on is set at logical zero) to control part 50.Thus, control part 50 does not drive toilet seat 22.
Here, generally have under the situation of higher harmonic components, will produce noise at the electric current that offers electronic equipment.In the present embodiment, under the situation that the 1200W that as above carries out toilet seat 22 drives or 600W drives, the electric current that offers toilet seat 22 changes to depict sinusoidal mode, so, even the size of electric current increases, also can fully reduce generating noise.
And, under the situation that the low-power of carrying out toilet seat 22 drives, have higher harmonic components though offer the electric current of toilet seat 22, but, because the size of current the when size of current of this moment is far smaller than 1200W driving and 600W driving, so, generating noise fully reduced.
As mentioned above, in the present embodiment, be with the power drive toilet seat 22 of 1200W, 600W and about 50W, but, also can drive toilet seat 22 by other big or small power.
For example, make alternating current flow through toilet seat 22 half period during situation under, set the timing of flowing through alternating current with the interval of 2 cycles or 3 specified period such as cycle.Thus, can with 1200W, 600W and the about power of the different sizes of 50W, fully preventing to drive toilet seat 22 under the situation that noise produces.
In addition, in the present embodiment, when the energising control signal is logical one, 50 pairs of toilet seats 22 of control part provide electric current, when the energising control signal is logical zero, stop to provide electric current to toilet seat 22, but, also can stop to provide electric current during for logical one, provide electric current to toilet seat 22 during for logical zero in the energising control signal in the energising control signal to toilet seat 22.
In addition, owing to be to control switching on and off of lamp heater 29 according to the time, so, when the time measures existing deviation, will cause the temperature of toilet seat 22 to surpass setting or do not reach setting.Therefore, do not produce deviation, in control part 50, utilize 2 instrumentation sources carrying out instrumentation the turn-on time of toilet seat 22 in order to make the time instrumentation.Instrumentation source utilizes the oscillator of effective speed of the program of having stipulated control part 50 to carrying out instrumentation the turn-on time of lamp heater 29, and another instrumentation source is that benchmark is to carrying out instrumentation the turn-on time of lamp heater 29 with cycle of alternating voltage.When at least one side in their the instrumentation value exceeds schedule time, transfer to next powered-on mode.
Particularly the time of with 1200W toilet seat being switched on, can prevent intensification reliably by instrumentation exactly.Thus, the security of equipment further improves.Here, put down in writing by a plurality of instrumentations source is set and improved the method for instrumentation precision, still, following method also can access same effect, this method is: to carrying out instrumentation the maximum conduction time of lamp heater 29, cut off or limit the energising at heater forcibly.
＜3〉action of notice LED
Be provided with notice LED 280 (Fig. 1) at the upper surface of main body 21 as notification unit.When beginning 29 energisings of lamp heater, notice LED 280 begins flicker, and when the temperature of toilet seat 22 rose to described creeping chill critical-temperature (29 ℃), notice LED 280 lighted.
Be lower than under the situation of creeping chill critical-temperature in detected temperatures (the mensuration temperature of thermistor 44), notice LED280 carries out the flicker as the 1st notice form, be higher than in detected temperatures under the situation of creeping chill critical-temperature, notice LED280 carries out lighting as the 2nd notice form, by observing notice LED 280, can differentiate the face of the taking a seat cold that whether can allow the user feel toilet seat 22, thereby be seated at toilet seat 22 in view of the above.
And, the function that has or not human body in the detection toilet of utilization by body detecting part's 25 realizations, when leaving the toilet from the user and passed through certain hour (for example 1 minute), the energising of stopping light heater 29, no matter notice LED 280 is in blink states or is in illuminating state, all extinguish notice LED 280.And,, but when toilet cover is closed, also extinguish notice LED 280 even if do not pass through certain hour as yet.
As mentioned above, the notice of notice LED 280 is period of the 2nd notice form to be that the temperature of the face of taking a seat of toilet seat 22 is when reaching 29 ℃ of critical-temperatures from the 1st notice variation.
Fig. 9 shows the relation between the mensuration temperature value of the temperature of the face of taking a seat of toilet seat 22 and thermistor 44.As shown in Figure 9, for the value of the mensuration temperature of the temperature of the face of taking a seat of toilet seat 22 and thermistor 44 each other for because mensuration face difference there are differences between them.For the toilet seat of moment intensification, the temperature-responsive of thermistor 44 lags behind, and can't detect the temperature of the face of taking a seat of toilet seat 22 exactly.Therefore, promptly light in the 2nd notice form of carrying out based on the mensuration temperature value of thermistor 44 under the situation of notice LED 280, need measure the degree of correlation between the mensuration temperature value of the temperature rising value of toilet seat 22 and thermistor 44 in advance, the error of predicted temperature response.
For example, under the intensification of thermistor 44 situation than the intensification low 10% of the face of taking a seat of toilet seat 22, during temperature rising 11deg (degree) of the face of taking a seat of toilet seat 22 from 18 ℃ to 29 ℃ in, the intensification of thermistor 44 is 9.9deg.Therefore, as long as when thermistor 44 detects 27.9 ℃, will notify LED 280 to switch to light and get final product from flicker.
And, also can measure in advance the detected temperatures of the thermistor 44 before the energising beginning and the face of taking a seat of toilet seat 22 at this moment reach the creeping chill critical-temperature required reach the degree of correlation between the time, temperature during according to the energising beginning decides the required time of arrival notice change.For example the temperature t before energising 0 is under 18 ℃ the situation, it is 5.5 seconds that the face of taking a seat is warmed up to 29 ℃ of required time t1, and if t0 is 20 ℃, then t1 is 4.5 seconds, produce the degree of correlation by this way, thereby only utilize initial stage temperature (being t0) can change notice.Detection at thermistor 44 postpones under the big situation, and this structure is very effective.
But, the temperature and the degree of correlation that reaches between the time during about the degree of correlation between the temperature of the face of taking a seat of the mensuration temperature value of thermistor 44 and toilet seat 22 and energising beginning, the very difficult individual deviation of considering that in advance voltage, room temperature etc. are provided with environment and cause because of the deviation of the resistance value of lamp heater 29 etc.In this case, can't notify to the user in appropriate period, so, need proofread and correct according to environment for use and individual difference.
＜4〉correction that realizes by the room temperature detecting sensor
Now following situation is described:, the notice of notice LED 280 is proofreaied and correct period according to temperature in the toilet for the error between the temperature of the face of taking a seat of the mensuration temperature value of eliminating thermistor 44 and toilet seat 22.Here, according to by the room temperature detecting sensor 48 detected room temperatures of being located in the main body 21, use corrected value based on heat dissipation capacity, notify the correction in notice period of LED 280, described heat dissipation capacity is stored in the storage part of control part 50 in advance, and sets accordingly with various room temperatures.The surface temperature of the portion of taking a seat of the mensuration temperature value of thermistor 44 and toilet seat 22 and the relation in the period of notice when Figure 10 shows the room temperature change.
It is 15 ℃ for example in room temperature (being designated as RT among Figure 10), be under 18 ℃ the situation with toilet seat 22 insulation, if error is 10% (with respect to the programming rate of the surface temperature of the portion of taking a seat of toilet seat 22, thermistor 44 detected programming rates are " 10% "), be that creeping chill critical 29.0 ℃ (from 18 ℃ of standby temperature, the 11 ℃ of temperature that reach that rise) is relative then with the surface temperature of the portion of taking a seat of toilet seat 22, the detected temperatures of thermistor 44 is 27.9 ℃ (adding the value after deducting 10% 9.9 ℃ of obtaining from 11 ℃ in 18 ℃ of standby temperature), based on this temperature notify status is changed to from flicker and lights.Be that the heat radiation of toilet seat 22 is big under 5 ℃ the situation in room temperature, error is little.For example under error was 8% situation, the error that should proofread and correct was 0.88deg, as long as change notify status with 28.12 ℃.
In above present embodiment, be period that the situation of creeping chill critical-temperature is illustrated to notice, still, notice also can be design temperature or be the temperature of benchmark with this design temperature period.
As the unit of grasping the common temperature control temperature that reaches of design temperature (for example at) exactly, also can use flexibly.That is, also can not change notice period, and be to use energising change period.Energising control changes according to from 1200W to 600W or approximately phase controlling and the toilet seat surface temperature of 50W, and still, energising control also can be used for this change correction in period.By proofreading and correct, can grasp the situation that the toilet seat surface temperature reaches 38 ℃ exactly, so comfortableness increases.
As mentioned above, the programming rate of toilet seat surface temperature is fast, produces operating lag in the thermistor 44 as detecting unit, so though the toilet seat surface temperature has reached design temperature, detecting unit detects the temperature that is lower than design temperature.This error and notice are same period, because of the deviation of the resistance value of voltage, room temperature and toilet seat heater that environment is set changes.Thus, reach temperature, can become more comfortable toilet seat by carrying out and notice identical correction in period, can grasping exactly.
For design temperature, under the situation of operating lag greater than the delay of hypothesis in advance, the toilet seat surface temperature reaches the temperature higher than design temperature especially.Therefore, in this case, proofread and correct, thus, can further improve comfortableness and security according to environment temperature (temperature in the toilet).
Particularly under the low situation of room temperature, utilize the heat radiation of toilet seat 22 big, the little character of error between the mensuration temperature of toilet seat surface temperature and thermistor 44, thus, under the low situation of room temperature, can also reduce the target temperature of the thermistor corresponding 44 and the people holding temperature (being 18 ℃ in the present embodiment) when not entering standby in the toilet with design temperature.In this case, can expect to reduce the effect of power consumption.
On the other hand, according to Figure 10 as can be known, under the high situation of room temperature, the holding temperature during for identical standby, because the programming rate from this holding temperature to design temperature is fast, toilet seat 22 heating in advance.Utilize this character, can also reduce the holding temperature (in the present embodiment be 18 ℃) of people when not entering standby in the toilet.In this case, also can expect to reduce the effect of power consumption.
＜5〉the standby temperature control that realizes by the room temperature detecting sensor
Then, control to control part 50 describes, this control is used to realize following purpose: according to temperature in the toilet, when the low-power of the lamp heater 29 during standby in (Fig. 5 during D1, D10 etc.) drove, the energising that changes at lamp heater 29 reduced power consumption.
Such as already explained, according to the height of temperature in the toilet (environment temperature), the heat dissipation capacity difference of toilet seat 22.For example, in the toilet under the relative condition with higher of temperature, less relatively from the heat dissipation capacity of the face of taking a seat of toilet seat 22.Therefore, hypothesis will be made as at the power of lamp heater 29 energising with the toilet in temperature when low under the identical situation, heat dissipation capacity is few, correspondingly becomes higher temperature, thereby may surpass the standby temperature (for example 18 ℃) that sets.Like this, with consuming unnecessary electric power, so undesirable.
Therefore, in the seat device of present embodiment, detect temperature in the toilet by room temperature detecting sensor 48, in the toilet under the relative condition with higher of temperature, be controlled to be the current on time (i.e. Tong Dian power) of reduction at lamp heater 29, on the other hand, in the toilet, under the relatively low situation of temperature, be controlled to be the increase current on time.
Figure 14 illustrates in this wise the curve map of an example that changes the mode of current on time according to temperature in the toilet,, utilizes the duty of explanation in Fig. 6～8 recently to represent current on time here.As shown in Figure 14, be set at: the temperature shown in the transverse axis is relatively high more, and dutycycle is more little, and in other words current on time is more little.Therefore, regardless of variation of temperature in the toilet, all can make toilet seat 22 the face of taking a seat temperature maintenance the regulation the standby temperature.
Therefore, for example under the situation that temperature is high in the toilet, can suppress following situation: standby is in the state that surpasses regulation standby temperature, and then is warmed up to the above temperature of necessary degree etc., produced unnecessary power consumption.And on the contrary, under the situation that temperature is low in the toilet, can avoid following situation: insulation thereby can't be warmed up in the expected time in user's inlet chamber the time and uses the initial target temperature below the standby temperature of regulation.
In addition, as the timing that detects temperature in the toilet to send to control part 50, can be made as body detecting part 25 when detecting human body.And, also can in body detecting part 25 or remote controller (not shown), timing unit be set, every through certain hour, detect temperature in the toilet.According to the up-to-date room temperature information that obtains like this standby temperature is after this controlled.
＜6〉the room temperature detecting sensor is shared
In addition, the control part 50 of present embodiment is for example between the 1st temperature raising period shown in Figure 5 in the D3, carry out the 1st step, carry out the 2nd step afterwards, described the 1st step is: the signal of thermistor 44 and room temperature detecting sensor 48 during based on the energising beginning, carry out computing according to both temperature differences or temperature separately, the optimum value of the energising binding hours that selection preestablishes and stores, when the elapsed time by timer portion 49 instrumentations reached the energising binding hours, reducing the energising amount or making the energising amount was zero; Described the 2nd step is: the signal based on thermistor 44 is controlled the energising amount, makes the portion of taking a seat of toilet seat 22 become appropriate temperature.
In the toilet of present embodiment, be provided with the warm warm portion 52 of indoor system of system that carries out in the toilet, the signal of the room temperature detecting sensor of as above utilizing from control part 50 48 detects in the warm portion 52 of this indoor system in the 1st step, thus, carry out the output control of warm heater 53 of indoor system and indoor system warm braw fan 54.Like this, utilize same temperature sensor to carry out the temperature control and the warm temperature control of indoor system of toilet seat, thus, do not need to be provided with the special-purpose temperature sensor of toilet seat control, toilet seat temperature that can implementation structure is simple, cost is low, precision is high and comfortable is controlled.Equally, about in during standby at the detecting unit of temperature in the employed toilet in the control of the current on time of lamp heater 29, also shared with the temperature sensor that in the warm temperature control of indoor system, uses, thus, can access same effect.
