In addition, main body 200 has control unit 600, heater-driven portion 610 and Dump portion 620 etc. in inside.
Control unit 600 include have microcomputer main control unit the 601, the 1st excessively rise preventing portion (the 1st excessively on Rising prevents control unit 602), the 2nd excessively rise preventing portion (the 2nd excessively rise prevent control unit 603), the 3rd excessively rise and prevent Portion's (the 3rd excessively rising prevents control unit 604) etc..Main control unit 601 is according to the operation portion from remote controler 500 and main body 200 The temperature detection signal of 211 operation signal and the 1st thermistor 401 controls toilet seat via heater-driven portion 610 and adds The powered-on capacity of hot device 450.Specifically, heater-driven portion 610 is constituted using three terminal bidirectional switch as main composition part, And according to the control signal of main control unit 601, toilet seat heater 450 is driven.
Control unit 602 is prevented to constitute in addition, the 1st excessive rising preventing portion is excessively risen by the 1st, according to as low-response temperature The temperature detection signal of the 1st thermistor 401 of detecting element is spent, carry out toilet seat 400 excessively rises the control prevented.2nd Excessively rise preventing portion prevents control unit 603 to constitute by the 2nd excessively rising, according to the 2nd as low-response temperature detecting element The temperature detection signal of thermistor 402 carries out the control that the excessive temperature rise of toilet seat 400 prevents.3rd excessively rise preventing portion by 3rd excessively rising prevents control unit 604 to constitute, according to the temperature of the 3rd thermistor 403 as high response temperature detecting element Signal is detected, the control that the excessive temperature rise of toilet seat 400 prevents is carried out.
Also, Dump portion 620 is constituted using relay as main composition part, anti-according to excessively rising from the 1st Only control unit the 602, the 2nd, which excessively rises, prevents control unit the 603, the 3rd from excessively rising the control signal for preventing control unit 604, cutting The power supply of seat device 100.
In addition, the seat device 100 of present embodiment is additionally provided with above-mentioned temperature also at the rear portion of toilet seat heater 450 Fuse 454 is spent, excessively rises preventing portion as the 4th.As a result, the 1st excessively rise preventing portion, the 2nd excessively rise preventing portion, 3rd excessive rise in preventing portion generates unfavorable condition, thus in the case where having risen to predetermined temperature or more, temperature fuse 454 fusing, thus energization of the cutting to toilet seat heater 450.
That is, the seat device 100 of present embodiment has the excessive rising preventing portion in 4 stages.
Hereinafter, to the specific 1st excessively rise preventing portion, the 2nd excessively rise preventing portion, the 3rd excessively rise preventing portion and 4th movement for excessively rising preventing portion is illustrated.
Firstly, main control unit 601 receives the temperature detection signal of the 1st thermistor 401.Then, by miniature computer Calculate the human testing of the operation signal and setting signal, remote controler 500 that send from remote controler 500 and the operation portion of main body 200 211 The data such as sensor 502 and the detection signal for detection switch of taking a seat of main body 200.Main control unit 601 is by toilet seat 400 as a result, Temperature control is predetermined temperature.At this point, the maximum temperature for the toilet seat 400 that main control unit 601 controls is set as such as 43 DEG C.
Here, the 1st excessively rising prevents the excessively rising of control unit the 602, the 2nd from preventing excessive rise of control unit the 603, the 3rd from preventing Only control unit 604 from the different circuits that main control unit 601 separates by constituting.Also, the 1st excessively rises and prevents control unit 602, the 2 excessively risings prevent the excessively rising of control unit the 603, the 3rd from control unit 604 being prevented to be made of respectively independent different circuits.According to The structure, main control unit the 601, the 1st, which excessively rises, prevents the excessively rising of control unit the 602, the 2nd from preventing control unit 603 and the 3rd excessively Rising prevents control unit to be configured to not influenced by other control functions respectively, individually functions the mistake for preventing toilet seat 400 Degree heating.
That is, the 1st excessively rising prevents control unit 602 from connecting with the 1st thermistor 401.Also, according to the 1st thermistor 401 temperature detection information, driving power cutting portion 620 are cut off the power.At this point, the 1st excessively rising prevents control unit 602 will Determine that the threshold value of excessive propradation sets for such as 45 DEG C.According to the setting, on the surface in the face 411 of taking a seat of toilet seat 400 At the time of temperature has risen to about 45 DEG C, cut off the power.
In addition, the 2nd excessively rising prevents control unit 603 from connecting with the 2nd thermistor 402.Also, according to the 2nd temperature-sensitive electricity The temperature detection information of resistance 402, driving power cutting portion 620 are cut off the power.At this point, the 2nd excessively rising prevents control unit 603 The threshold value for determining excessive propradation is set for such as 46 DEG C.Table according to the setting, in the face 411 of taking a seat of toilet seat 400 At the time of face temperature has risen to about 46 DEG C, cut off the power.
Control unit 602 is prevented in addition, the 2nd excessively being risen, the threshold value of control unit 603 being prevented to be set to rise more excessive than the 1st The high reason of threshold value be, it is contemplated that the temperature characterisitic deviation of the 1st thermistor 401 and the 2nd thermistor 402.
By using above structure, the temperature control function realized by the 1st thermistor 401 and main control unit 601, with And excessively rises the prevent control unit 602 from realizing the 1st by the 1st thermistor the 401 and the 1st and excessively rise the normal situation of preventing portion Under, such as the 1st, which is excessively risen, prevents control unit 602 and the 2nd excessively rising from preventing the threshold value of control unit 603 from setting in order to identical When temperature, due to the characteristic deviation of the 2nd thermistor 402, sometimes results in excessively to be risen by the 2nd thermistor the 402 and the 2nd and prevent The 2nd excessively rising preventing portion rising preventing portion excessively than the 1st that only control unit 603 is realized first works.Therefore, by the 2nd excessively on Rising, which prevents the threshold value of control unit 603 to be set to rise more excessive than the 1st, prevents the threshold value of control unit 602 high.Thereby, it is possible to prevent 2, which excessively rise preventing portion, excessively rises the case where preventing portion first works than the 1st.As a result, it is possible to prevent from unexpectedly cutting off to place In the malfunction of the energization of the seat device 100 of normal condition.
In addition, the 3rd excessively rising prevents control unit 604 from connecting with the 3rd thermistor 403.Also, according to the 3rd temperature-sensitive electricity The temperature detection information of resistance 403, driving power cutting portion 620 are cut off the power.At this point, the 3rd excessively rising prevents control unit 604 The threshold value for determining excessive propradation is set for such as 55 DEG C.According to the setting, in temperature-rise period sharply, due to The detection temperature of 3 thermistors 403 and the temperature in face of taking a seat generate difference, therefore the surface temperature in the face 411 of taking a seat of toilet seat 400 Degree is cut off the power at the time of having risen to about 55 DEG C.At the moment, the inspection of the 1st thermistor 401 and the 2nd thermistor 402 Testing temperature does not rise to 45 DEG C.Therefore, the 1st excessively rising preventing portion and the 2nd excessively rising preventing portion does not work.
According to above structure, such as even if generating exception in main control unit 601, without suitably carrying out toilet seat heater 450 Power control, thus toilet seat 400 constant temperature rise in the case where, also can by the 1st excessively rise prevent control unit 602 cut off the power.Thereby, it is possible to prevent toilet seat 400 from reaching 45 DEG C or more as given threshold.
Moreover, even if can also pass through the 2nd mistake in the case where the 1st excessively rising prevents control unit 602 from producing exception Degree, which rises, prevents control unit 603 from cutting off the power.Thereby, it is possible to prevent toilet seat 400 from reaching 46 DEG C or more as given threshold.
In addition, why be arranged the 1st thermistor the 401 and the 1st excessively rise prevent control unit 602, the 2nd thermistor and 2nd excessively rising prevents control unit 603, is to cope with the guarantor after the surface temperature in the face of taking a seat 411 has reached set temperature Wen Shi, because it is using that Figure 14 illustrates, rise than more gentle temperature caused by excessive propradation.Therefore, the 1st thermistor 401 and the 2nd thermistor 402 is made of low-response temperature detecting element.
On the other hand, the 3rd excessively rising of thermistor the 403 and the 3rd, which why is arranged, prevents control unit 604, is in order to anti- Excessive rising when only just having detected into steep temperature rise after the human body of toilet, toilet seat 400.That is, adding in toilet seat It in the state that hot device 450 is for example powered with 800W, is coped with, to prevent excessive rising when temperature rising sharply State.Therefore, the 3rd thermistor 403 is made of to cope with temperature rising sharply height response temperature detecting element.
That is, by the 3rd thermistor 403 detection toilet seat 400 of fireballing high response temperature detecting element in response Take a seat face 411 dramatic temperature rise.Thereby, it is possible to the surface temperature in the face 411 of taking a seat of toilet seat 400 rise to high temperature it Before, cutting is powered.As a result, it is possible to will test, delay is caused, temperature rising of sharply prevents trouble before it happens.
The powered-on mode and temperature change of 6 > toilet seat heater of <
Hereinafter, the powered-on mode and temperature change of the toilet seat heater in 2 pairs of embodiment of the present invention are said referring to Fig.1 It is bright.
Figure 12 is the temperature change of the powered-on mode for showing the toilet seat heater in the embodiment and each section of toilet seat Curve graph.In addition, Figure 12 shows powered-on mode when seat device 100 is controlled with normal state.

1st powered-on mode is following mode: human body detection sensor 502 detect disengaging toilet human body it Afterwards, main control unit 601 makes toilet seat 400 in a short time with temperature gradient heating sharply at once.In this case, according to main control The control signal in portion 601, heater-driven portion 610 are driven by electricity toilet seat heater 450 (below by the driving with about 800W's State is referred to as " 800W driving ").
2nd powered-on mode is following mode: being driven by above-mentioned 800W, the temperature of toilet seat 400 is rising to regulation Temperature after, to drive slightly gentle temperature gradient to rise than 800W.At this point, heater-driven portion 610 is switched to about The electric power of 400W drives toilet seat heater 450 (below by the driving condition be referred to as " 400W driving ").
3rd powered-on mode is following mode: in the case where the temperature of toilet seat 400 is remained constant, heater is driven Dynamic portion 610 is for example driven by electricity toilet seat heater 450 (driving condition is referred to as " low to be driven by electricity " below) with 30W.Separately Outside, low to be driven by electricity the power supply for being not limited to above-mentioned 30W, refer to using sufficiently low compared with 800W driving and 400W driving Electric power (such as electric power in the range of 15W~150W) drives toilet seat heater 450.
In addition, 800W driving, 400W driving and the low switching being driven by electricity are the control signals according to main control unit 601, Phase controlling is carried out to the energization in toilet seat heater 450 by heater-driven portion 610 and is carried out.
Here, the solid line shown in the upper section of Figure 12 indicates the surface temperature in the face 411 of taking a seat of toilet seat 400.Chain-dotted line indicates The surface temperature of the aluminium flake 451 of the toilet seat heater 450 of mounting portion as each thermistor.Dotted line indicates the 1st thermistor The detection temperature of 401 and the 2nd thermistor 402.Dotted line indicates the detection temperature of the 3rd thermistor 403.Also, under Figure 12 Solid line shown in section indicates the powered-on capacity of driving toilet seat heater 450.Also, above-mentioned each surface is shown with same time shaft The time change of temperature and powered-on capacity.
In addition, the seat device 100 of present embodiment is constituted are as follows: user can be in the range of such as 32 DEG C~38 DEG C Set the surface temperature (temperature is referred to as " set temperature " below) in the face 411 of taking a seat of toilet seat 400.
In addition, room temperatures are in 18 DEG C of situations below, when seat device 100 is in standby, by toilet seat 400 in winter etc. Take a seat face 411 surface temperature setting in order to maintain 18 DEG C (below by the temperature be referred to as " standby temperature ").
Therefore, it is first assumed that by standby temperature be set as 18 DEG C, user by set temperature set for 38 DEG C the case where.And And it will be described below under the above conditions, the temperature history of the toilet seat 400 of the driving based on toilet seat heater 450.
Firstly, the main control unit 601 of control unit 600 by human body detection sensor 502 detect user entrance to When machine, heater-driven portion 610 is driven, (about 15W) is driven by electricity using low and drives toilet seat heater 450.It as a result, will just The surface temperature control in the face 411 of taking a seat of seat 400 is to be fixed on 18 DEG C.At this point, the temperature about toilet seat 400 controls, according to work Temperature detection information for the 1st thermistor 401 of the 1st temperature detecting element is controlled.
Then, main control unit 601 at T1, keeps heater-driven portion 610 sharp at the time of the entrance for detecting user Toilet seat heater 450 is driven with 800W driving.Then, it is preset 1st heating during (such as 6 seconds (moment T1 to when Carve T2)), continue the 800W driving of toilet seat heater 450.800W driving substantially utilizes meter possessed by main control unit 601 Shi Gongneng is performed by time control.During implementing 800W driving, each section of toilet seat 400 is with most precipitous temperature Gradient is spent to rise.
Also, the surface temperature in the face 411 of taking a seat that the 800W driving of toilet seat heater 450 is performed until toilet seat 400 reaches To predetermined temperature (about 30 DEG C).In addition, predetermined temperature can not be the temperature for sufficiently having risen to set temperature, and can compare Its is low.As long as that is, will not feel ice-cold such uncomfortable minimum critical-temperature when user is seated at the face 411 of taking a seat (temperature is referred to as " creeping chill critical-temperature " below).Here, it is tested according to the testee that inventor is implemented, creeping chill Critical-temperature is about 29 DEG C.Therefore, in the present embodiment, creeping chill critical-temperature is set for 30 DEG C.
Then, at the time of 800W drives completion at T2, the surface temperature in the face 411 of taking a seat of toilet seat 400 rises to creeping chill More than critical-temperature about 30 DEG C.Therefore, at moment T2, user can be seated at toilet seat 400, without may feel that just Seat 400 is ice-cold.
At this point, during moment T1 to moment T2, as shown in figure 12, the surface temperature of the aluminium flake 451 of toilet seat heater 450 Degree rises to about 60 DEG C.In addition, the detection temperature of the 1st thermistor 401 and the 2nd thermistor 402 rises to about 24 DEG C. Also, the detection temperature of the 3rd thermistor 403 rises to about 40 DEG C.
Then, main control unit 601 at T2, starts the 400W driving of toilet seat heater 450 at the time of 800W, which drives, to be terminated. Also, T3 at the time of surface temperature of the main control unit 601 in the face 411 of taking a seat of toilet seat 400 reaches set temperature (such as 38 DEG C) Before, continue 400W driving.During this period, the surface temperature in the face 411 of taking a seat of toilet seat 400 is according to gentle when driving than 800W Temperature gradient rises.In addition, the 400W driving of toilet seat heater 450 is performed until the surface temperature in the face 411 of taking a seat of toilet seat 400 Degree reaches toilet seat set temperature (38 DEG C).
Then, at moment T3, when the detection temperature of the 1st thermistor 401 reaches set temperature (38 DEG C), stop 400W driving, is switched to next driving.
In general, generating is more than to set when steeply rising the surface temperature in face 411 of taking a seat of toilet seat 400 to set temperature Determine the overshoot of temperature.But in the present embodiment, the surface temperature in the face 411 of taking a seat of toilet seat 400 has reached lower than setting When creeping chill critical-temperature (30 DEG C) of temperature, terminate the 800W driving of toilet seat heater 450.Also, powered-on capacity is cut later It is changed to 400W driving, drives toilet seat heater 450.Thereby, it is possible to inhibit the surface temperature in the face 411 of taking a seat of toilet seat 400 from setting Determine temperature overshot.As a result, it is possible to prevent user from feeling when taking a seat, toilet seat 400 is hot.
Then, at the time of 400W, which drives, to be terminated at T3, the low electric power for starting toilet seat heater 450 drives main control unit 601 It is dynamic.Then, main control unit 601 control at: so that the surface temperature in the face 411 of taking a seat of toilet seat 400 is fixed on toilet seat set temperature (38℃).The state is the normal use state for the temperature of toilet seat 400.Therefore, user can be seated at toilet seat Use is carried out cosily in 400 face 411 of taking a seat.
Then, although being not shown in Figure 12, when terminating defecation in user, and being left from toilet seat 400, by taking a seat Switch detection user's disseats.Detecting that main control unit 601 is stopped after specified time limit (such as 1 minute) when disseating The only driving of toilet seat heater 450.The surface temperature in the face 411 of taking a seat of toilet seat 400 reduces as a result,.
In turn, at the time of the surface temperature of toilet seat 400 has reached 18 DEG C, main control unit 601 starts again at toilet seat heating The low of device 450 is driven by electricity.Then, main control unit 601 remains low and is driven by electricity, so that the surface temperature of toilet seat 400 is fixed on 18℃。
In addition, hereinbefore, for assuming that user is seated at the powered-on mode for the case where toilet seat 400 is used It is illustrated.
