On main body 21, be provided with control part 49 based on microcomputer, this control part 49 is taken into as the go forward side by side temperature control of portable lighter heater 30 of the detection signal of the room temperature thermistor 47 of room temperature detector, and have timing portion 48,48 pairs in this timing portion begins elapsed time from the moment that begins to heat up by lamp heater 30 energisings to seat ring 22 and carries out timing.And, control part 49 is taken into and detects the interior human body detection sensor 26 of people's inlet chamber or the signal of take one's seat checkout gear 38 and seat ring position detecting device 46, control is to the beginning of lamp heater 30 energising and stop, and be taken into signal from thermistor 43, room temperature thermistor 47, lamp heater 30 is carried out temperature control, so that reach predetermined temperature as preference temperature as the temperature of the portion of taking one's seat 25 of heating face.
In Fig. 8, thermostat 31 relatively constitutes with lamp heater 30 in blank part 28, so that the emittance of bimetallic 50 receiving light heaters 30.And,, be coated with as radiation-absorbing material 51 stable on heating blacking be housed at the light receiving surface of bimetallic 50.And, thermostat 31 by radiation-absorbing material 51 efficient absorption from the radial pattern heater to the near infrared ray of bimetallic 50 radiation to the heat that middle infrared (Mid-IR) produces, can improve the temperature of bimetallic 50 apace.And thermostat 31 is set for, lamp heater 30 and bigger than the distance b between lamp heater 30 and the bimetallic 50 apart from a between the portion 25 of taking one's seat.This apart from a represent to be located on the portion's of taking one's seat 25 inner surfaces as the distance till the radiant heat absorbed layer 40 of sensitive surface.
In the above-described embodiment, when the user entered the lavatory, human body detection sensor 26 detected it and enters, and this signal is sent to control part 49.At this moment, when confirming that according to the signal of seat ring position detecting device 46 seat ring 22 is in the use location of approximate horizontal, control part 49 beginnings are to 30 energisings of lamp heater.Convert energy moment of dropping into to emittance by this initial power-up, from filament 34 through quartz glass tube 33 and radiation reflecting plates 29, the direction radiation to the portion of taking one's seat 25 of seat ring 22.And then the emittance of lamp heater 30 makes radiant heat absorbed layer 40 and the portion 25 of taking one's seat heats up.Like this, in the present embodiment, when the user enters the lavatory, to 30 energisings of lamp heater, the heating face of the portion of taking one's seat 25 of transient heating seat ring 22 almost, and, for unexpected dangerous states of affairs such as control part 49 break down, the thermostat 31 of the high-speed response of the emittance by bimetallic 50 receiving light heaters 30, energising that can turn-off lamp heater 30, thus with the insulation of switching on like that all the time of the existing general heating seat ring that uses, heat release is lost bigger device differently, can realize almost not having the heat release loss, extremely energy-conservation and safe heating seat ring.In addition, the part of Fig. 3 and hinged cover 53 shown in Figure 4, under the situation of the heating seat ring (not shown) of the general resin that uses, integrally formed in the past with the portion of taking one's seat 25.In the above-described embodiment, the portion 25 of taking one's seat is metal (aluminium), and hinged cover 53 is shaped by allyl resin.Its reason is, will be restricted to required Min. with the position that lamp heater 30 heats, and reduces the thermal capacity that should heat, thus can with still less electric power quick moment the portion of taking one's seat 25 is heated up, more energy-conservation.That is, the thermal conductivity height of the aluminium of the portion 25 of taking one's seat has played by heat conduction making temperature become effect uniformly, but hinged cover 53 is made of resin, and thermal conductivity is low, therefore can absorb the heat of the portion of taking one's seat 25 hardly.Like this, the parts of seat ring 22 upsides are made of the different a plurality of parts of thermal conductivity, can suppress heat and be absorbed redundantly by the part that does not need to heat, and can reduce heat loss.As mentioned above, comprising: by the seat ring 22 27 that constitute as the portion of taking one's seat 25 of the upside component parts of seat ring 22 and hinged cover 53 and lower frame body, that inside has blank part 28; Be located at the radial pattern heater 29 in the blank part 28; Relatively be located at the reflector 28 of lower frame body 27 1 sides with this radial pattern heater 29, at least the portion of taking one's seat 25 of upper frame body 24 is made of metal (aluminium), the portion of taking one's seat 25 inner surfaces at upper frame body 24 are provided with radiant heat absorbed layer 40, can realize a kind of with small electric power quick moment the portion of taking one's seat 25 is heated up energy-saving seat ring.
And, the thermistor 43 when control part 49 begins based on energising and the signal of room temperature thermistor 47, carry out computing according to both temperature differences and temperature separately, the optimum value of the energising binding hours of the initial power-up that selection preestablishes and stores, when the elapsed time of timing portion 48 accumulative totals reaches the energising binding hours, reduce the energising amount or be zero, thereafter based on the signal controlling energising amount of thermistor 43, so that the portion 25 of taking one's seat reaches preference temperature.
Thus, near the portion of taking one's seat 25 of thermistor 43 detection user actual contact temperature, control part 49 makes its intensification accurately and keeps preference temperature, therefore can cosily use seat ring 22, and signal based on thermistor 43 and room temperature thermistor 47, according to the input amount of load control emittance, therefore can high accuracy and be heated to preference temperature safely.
And, by preferentially carrying out the control of initial power-up time, after the energising binding hours, the energising amount reduces, and programming rate reduces, even therefore the response speed of seat ring temperature-detecting device is slower, seat ring 22 is heated, perhaps also can use cheap seat ring temperature-detecting device.Usually, general heater is controlled by the voltage that reduction applies mostly, but lamp heater 30 forms the halogen cycle reaction of tungsten halide repeatedly by the heating that is accompanied by filament 34, can prevent the consumption of filament 34, when therefore the temperature of quartz glass tube 33 becomes below 200 ℃, hinder halogen cycle.Therefore, utilize lamp heater 30 portion 25 of will taking one's seat to be made as preference temperature and to be undertaken by in the effective output area of halogen cycle, being changed in the energising cycle.
On the other hand, seat ring 22 is in the state of erecting, and after male sex user enters the lavatory, seat ring 22 is in when erecting state, and based on the signal of seat ring position detecting device 46, control part 49 stops to 30 energisings of lamp heater, or reduces delivery.Can reduce the situation that heats seat ring 22 thus meaninglessly, further realize energy-conservationly, and the tension direction that can prevent filament 34 under "on" position is to be subjected to the gravity effect on the length direction and the situation in the life-span of lamp heater 30 is shortened in disconnection etc.
And, purpose according to the user, even seat ring 22 was being opened and closed between the falling of state of erecting and approximate horizontal state, also can relax impact as the lamp heater fixture 36 of the leaf spring material of elastomeric material, therefore can prevent quartz glass tube 33 or filament 34 breakages.
Secondly, when the user sits down for defecation, make the energising quantitative changeization and control, so that be zero or amount for the seat ring excessive temperature is raise to the energising amount of lamp heater 30 according to the signal of the checkout gear 38 of taking one's seat.Thus, the seat ring temperature can excessively not raise in the use, does not worry scalding etc., can use safely.
Especially, because the heating seat ring makes skin directly contact the seat ring 22 that is built-in with lamp heater 30, therefore need make sufficient consideration to safety.Under common user mode, safety and comfort ground uses as mentioned above, but because of unexpected reason breaks down microcomputer control parts 49 such as (not shown), and but still continuing when lamp heater 30 is switched on etc. also needs to move safely under the situation.
Thermostat uses the structure that is wrapped in the bimetallic in the metal lid usually.In this structure, at first the main body of thermostat and lid are heated, heat transmission by coming autonomous agent and come bimetallic is heated from the secondary radiation of lid, therefore metal reaches the predetermined temperature position needs spended time, therefore under the situation that the temperature of seat ring 22 changes at short notice, the cut-out of circuit produces delay sometimes.
Yet in the present embodiment, in order to address this problem, the bimetallic 50 in the thermostat 31 exposes, at the stable on heating blacking of bimetallic 50 external coatings and as radiation-absorbing material 51.Therefore, because the emittance of bimetallic 50 direct receiving light heaters 30, therefore the emittance from lamp heater 30 directly adds thermo bimetal 50, and at the stable on heating blacking of the external coating of bimetallic 50 and as radiation-absorbing material, therefore the most of radiant heat that arrives bimetallic 50 from lamp heater 30 is absorbed by bimetallic 50, can follow the rapid change of seat ring 22 temperature.And thermostat 31 in series is electrically connected with lamp heater 30, therefore when excessive temperature raises, can cut off the energising of lamp heater 30.And the lid of thermostat 31 52 is made of clear glass, so that the emittance of bimetallic 50 receiving light heaters 30.In addition, by the lid 52 that clear glass is set, can be set as the antidrip or water proof type that water droplet or dust can not invaded thermostat 31 inside, even during just in case intake in the blank part 28, can prevent that also sealing enters the conducting parts of thermostat 31, can keep electric insulation, prevent to get an electric shock.
In addition, the clear glass of lid 52 uses quartz glass, thus the emittance of lamp heater 30 see through characteristic good, respond quicker, the raising seperating safety.Certainly, also can use other glass as required.And the plate of clear glass 53 is pressed when blocked up, and through performance reduces, and therefore preferred thickness of slab is below the 1.5mm, more preferably below the 1.2mm.And in the respective embodiments described above, the material of the portion 25 of taking one's seat is the punch process product of aluminium sheet, and other processing methods such as cast aluminium also can access same effect.The kind of metal also can be copper coin or steel plate.
And then, thermostat 31 is set in following position, make bigger than the distance between lamp heater 30 and the thermostat 31 between lamp heater 30 and seat ring 22 surfaces apart from a.Thus, the surface temperature of seat ring 22 rises very fast, and the temperature of bimetallic 50 is risen, therefore when unusual, can cause precarious position such as scald the time, not cut off the power-on circuit of lamp heater 30 reaching also that seat ring 22 surface temperatures excessively raise, be safe.
And, in the present embodiment,, then also can prevent the malfunction of thermostat 31 if the temperature of bimetallic 50 is raise fast.Promptly, if the temperature of bimetallic 50 is raise fast, then can set the disconnection of thermostat 31 (power-on circuit of lamp heater 30 disconnects) operating temperature for be higher than seat ring 22 common serviceability temperature, thermostat 31 work in the time of therefore can avoiding using usually and cause to use the heating function of seat ring 22.
That is, Fig. 9 is illustrated in the thermostat 31 of structure shown in Figure 8, distance b=7mm, and apart from a=15mm, the result of the surface temperature of near the temperature of bimetallic 50 and the portion 25 of taking one's seat when measuring 30 energisings of lamp heater.In Fig. 8, curve (A) is the surface temperature of the portion of taking one's seat 25, when room temperature is 5 ℃, and about 7.5 seconds (t
1) can be warmed up to common seat ring control temperature (T
1).On the other hand, the temperature of the bimetallic 50 of thermostat 31 is shown in curve (B), and is faster than the portion of taking one's seat 25, at t
2Time rises to seat ring control temperature (T
1).The portion 25 of taking one's seat reaches the highest design temperature (T of seat ring 22
2) when above, the temperature of bimetallic 50 reaches disconnection (opening circuit) operating temperature (T of thermostat 31
3), the power-on circuit of cut-out lamp heater 30.And, just in case thermostat 31 breaks down, become under the situation of state of the power-on circuit that can't cut off lamp heater 30, reaching safety margin temperature (T
4) before, the work of the thermostat 32 (or temperature fuse) of non-restoring type, the power-on circuit of cut-out lamp heater 30.At this moment, the surface temperature of seat ring 22 can not reach safety margin temperature (T
4).
And, with the operating temperature (T of thermostat 31
3) be set in the highest design temperature (T of seat ring
2) above and safety margin temperature (T
4) below, thus, the thermostat 32 (or temperature fuse) of having eliminated non-restoring type easily cuts off the power-on circuit of lamp heater 30 and causes using the danger of the heating function of seat ring 22.That is, the phase I of initial power-up time, the timer 48 of control part 49 and thermistor 43 carry out temperature control; Second stage is by disconnecting the power-on circuit (but because temperature reduces, circuit can restore) that thermostat 31 cuts off lamp heater 30; Phase III, cut off the power-on circuit (can't ReSet Circuit) of lamp heater 30 by the thermostat 32 (or temperature fuse) of non-restoring type, by the multilevel security function is set, safety and comfort ground uses for a long time.
And, in the present embodiment, as shown in Figure 3, the lamp heater 30b of the lamp heater 30 of front side and rear side is configured in the front and back of seat ring 22, and be provided with many, and with each lamp heater 30,30b thermostat 31,31b being set relatively, each thermostat 31,31b in series are electrically connected.In addition, restoring type thermostat 31,31b disconnect under lower slightly temperature, non-restoring type thermostat 32,32b disconnect under the temperature higher than restoring type thermostat 31,31b, can realize higher maltilevel security thus, and safety and comfort ground use for a long time.
Promptly, be connected in series with thermostat 31,31b on each lamp heater 30, the 30b, and then it is connected in series, constitute the power-on circuit of lamp heater 30,30b, which no matter produce when unusual thus at lamp heater 30,30b, can both pass through the power-on circuit of thermostat 31,32b cut-out lamp heater 30,30b, therefore can stop safely to two lamp heaters 30,30b energising.And, the disconnection operating temperature difference of thermostat 31,32, thus, when becoming the state of the power-on circuit that can't cut off lamp heater 30,30b just in case one of them thermostat 31 breaks down, also can utilize another thermostat 32 to cut off the power-on circuit of lamp heater 30,30b, thereby be safe.And, lamp heater 30,30b are divided into many, therefore, roughly on the whole the situation that is configured in the blank part 28 of seat ring 22 with 1 lamp heater 30 with ring-type is compared, since the deflection of seat ring 22 and the step-up error of lamp heater 30 etc. and directly on lamp heater 30 problem of stress application be eliminated, thereby can eliminate the danger of lamp heater 30 breakages that the deflection etc. of seat ring 22 causes.
