In Fig. 1 to Fig. 5, with the heating seat ring of warm water cleaning function of the anus after cleaning defecation or private parts, the main body 21 of growing crosswise is arranged on the rearward end of the closet 20 of toilet device, a part for built-in warm water cleaning function in this main body 21, and the seat ring 22 and the toilet cover 23 that are rotatably provided with the ring-type be placed on closet 20.Further, the human body detection sensor 25 detected with or without human body in lavatory is built-in with at the sidepiece of main body 21.Seat ring 22 is configured to, as shown in Figure 1 by the top of plastic lower frame body 26, be formed, have the blank part 27 of the drip-proof enclosure of the intrusion that can stop water droplet etc. therein by portion of taking one's seat 24 fixed engagement of encapsulant and aluminum.
In the inside of blank part 27, the portion of taking one's seat 24 of the seat ring 22 of taking one's seat with the user of use toilet device relatively, be provided with the radiant light reflecting plate 28 (reflector) obtained through mirror finish by aluminium sheet and the both sides being positioned at the portion of taking one's seat 24, as 2 lamp heaters 29 of multiple radial pattern heater.Radiant light reflecting plate 28 as shown in Figure 1, in it outer end all-round on have kink 28a upward, by this kink 28a, the radiant light that lamp heater 29 sends is partial to, therefore the effect promoted away from the edge, periphery in the portion of taking one's seat 24 of lamp heater 29 and the radiation density of Inner peripheral portions is played, the homogenising of the thermal radiation distribution in the portion 24 that realizes taking one's seat.Near this lamp heater 29, be provided with the thermostat 30 be in series electrically connected with lamp heater 29, play and prevent the effect that excessive temperature raises because of the dangerous state of affairs of unexpected generation of the portion of taking one's seat 24 of seat ring 22.In addition, radiant light reflecting plate 28 have employed aluminium sheet in order to lightweight, also can use corrosion resistant plate or steel plating plate.
Lamp heater 29 is configured to the halogen entering the inactive gas 34 such as filament 33, argon and the trace formed by tungsten at glass tube 32 inner sealing, by repeating the halogen cycle reaction occurring to form tungsten halide along with the heating of filament 33, the effect preventing filament 33 from consuming can be played.Can, using the very little filament 33 of thermal capacity as thermal source, emittance can be made to increase rapidly by this effect.That is, the so a kind of radial pattern heater of lamp heater 29, that is, such as user enters lavatory, takes off clothes, before buttocks is seated at the portion of taking one's seat 24 of seat ring 22, in the moment in a few second, the portion of taking one's seat 24 of seat ring 22 is rapidly heated to preference temperature.In addition, the situation of lamp heater 29 characteristic as requested might not be halogen lamp heater.
This lamp heater 29 is fixed on radiant light reflecting plate 28 by the lamp heater fixture 36 formed by leaf spring material, and radiant light reflecting plate 28 is fixed in the projection 37 of resinous lower frame body 26 by Screw.
Fig. 5 illustrates the amplification cross section of the part in the portion of taking one's seat 24 of the aluminum forming seat ring 22.In Figure 5, blank part 27 side of seat ring 22, namely by the inner surface of the radiant light of lamp heater 29, form the radiation absorption layer 42 that black is dressed up in the painting absorbing this radiant light easily, side of namely taking one's seat, outside is formed with the surface decoration layer 43 of the appearance of corrosion protection the aluminium lamination 41 and application hobby thereon with anticorrosion ability.In addition, the surface decoration layer 43 that corrosion protection aluminium lamination 41 and application are set simultaneously might not be needed, even certain one deck in the surface decoration layer 43 of corrosion protection aluminium lamination 41 or application, the anticorrosion ability of suitable chemical resistance etc. and the design of gloss and color etc. also can be had.But, if having the surface decoration layer 43 of corrosion protection aluminium lamination 41 and application simultaneously, higher anticorrosion ability and the bacteria-eliminating efficacy such as by using the coating containing degerming material to obtain just can be obtained.In addition, about the color of radiation absorption layer 42, confirm that the result obtained is to shades of colour, black is that heat absorption efficiency is best, can accelerate the color of the programming rate in the portion of taking one's seat 24.In addition, be not limited to prestissimo, if with can be practical viewpoint, even grey, redness, blueness etc. also can heat up.Even be not also be only limitted to application for black, the surface treatment of dyeing etc. also can be used.The process of alumite film is used also to be practical when aluminium.And, the surface decoration layer 43 that the outer surface in the portion of taking one's seat 24 of Fig. 5 is implemented can use dyeing process, also can application, if but at least carry out application on the surface in the portion of taking one's seat, not only obtain anticorrosion ability, even the metal back-up thimbles such as aluminium also can be eliminated seem cold sensation, such as, by the pearly-lustre application etc. that pearl is such, soft impression or senior impression can be deduced.
Portion of taking one's seat 24 due to seat ring 22 employs metal, is specifically punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200W/mK, differ greatly compared with the about 0.1 ~ 1W/mK of resin high, therefore at the radiant light of receiving light heater 29, heat promptly can be passed to outer surface and the surface decoration layer 43 in the portion of taking one's seat 24 while heating up by radiation absorption layer 42.And, owing to being the aluminium that thermal conductivity is high, therefore, it is possible to obtain the more uniform all thermal effects of Temperature Distribution.Further, processed by the punching press (deep-draw) of aluminium, due to work hardening, even if thickness of slab is thinning also can guarantee necessary intensity.Such as, when resin, from the angle of intensity, need the wall thickness of about 3mm, if the punch process product of aluminium sheet, then below the 1.5mm of a half thickness is namely enough.Due to thinner, thermal capacity is less, therefore, it is possible to reduce the heat required for heating up and time.From experimental result, intensity and the angle of heating-up time, the thickness of slab obtaining aluminium sheet is preferably the conclusion of 0.8 ~ 1.2mm.
Further, in the lower frame body 26 forming seat ring 22, its inner face is provided with radiant light reflecting plate 28, the thermostat 30 this radiant light reflecting plate 28 being provided with lamp heater 29 and being connected in series with lamp heater 29.Further, the top of lower frame body 26 is provided with the portion of taking one's seat 24 of aluminum, in order to detect the temperature in the portion of taking one's seat 24 of this aluminum, the inner surface in the portion of taking one's seat 24 is provided with the thermistor 44 as seat ring temperature-detecting device.And, seat ring 22 is formed with electrode 46 on its rotating shaft 45, jointly seat ring position detecting device 47 is formed, for detecting seat ring 22 for raised state, or for can take one's seat and the use location approximate horizontal on closet 20 used with the bearing portion (not shown) of main body 21.
The control part 50 based on microcomputer is provided with in main body 21, the detection signal be taken into as the room temperature thermistor 48 of room temperature detector controls to the temperature of carrying out lamp heater 29, and there is timing unit 49, the elapsed time that the moment the intensification caused being energized from the lamp heater 29 of seat ring 22 starts carries out timing.And, control part 50 receives detection people and enters indoor human body detection sensor 25, the signal of take one's seat checkout gear 38 and seat ring position detecting device 47, the start and stop of the energising of lamp heater 29 is controlled, receives signal that thermistor 44, room temperature thermistor 48 send and temperature is carried out to lamp heater 29 control to make the temperature as the portion of taking one's seat 24 in heating face to reach predetermined temperature as preference temperature.
In figure 6, thermostat 30 is expose in blank part 27 to make the radiant light of bimetallic 51 receiving light heater 29.Further, the light receiving surface of bimetallic 51 is coated with the heat resistance blacking as radiant heat absorbent material 52.And thermostat 30 is configured to effectively absorb heat from from radial pattern heater to bimetallic 51 radiation by radiant heat absorbent material 52, more promptly improves bimetallic temperature.Further, the thermostat 30 distance a be set between lamp heater 29 and the portion of taking one's seat 24 of seat ring 22 is greater than the distance b between lamp heater 29 and bimetallic 51.This distance a is the distance to the radiation absorption layer 42 as sensitive surface on the inner surface being located at the portion of taking one's seat 24 in the present embodiment.
In the above-described embodiment, when user enters lavatory, human body detection sensor 25 detects that it enters, and this signal is sent to control part 50.Now, when confirming that seat ring 22 is in approximate horizontal use location by the signal of seat ring position detecting device 47, control part 50 starts the energising to lamp heater 29.By this initial power-up, drop into energy and be transformed to emittance instantaneously, emitted to the direction, portion of taking one's seat 24 of seat ring 22 by filament 33 through glass tube 32 and radiant light reflecting plate 28.And then the emittance of lamp heater 29 makes the radiation absorption layer 42 of the inner surface in the portion of taking one's seat 24 being located at seat ring 22 and portion 24 of taking one's seat heat up.Like this, in the present embodiment, after user enters lavatory, can be energized to lamp heater 29, the almost heating face in the portion of taking one's seat 24 of transient heating seat ring 22, even and if for the unexpected dangerous state of affairs occurred such as fault of control part 50, also the energising of lamp heater 29 can be blocked by the thermostat 30 of the quick response of the radiant light by bimetallic 51 receiving light heater 29, therefore the situation that is incubated heat release loss very large of being energized like that all the time from the existing heating seat ring used in general manner is different, achieve and almost there is no heat release loss, extremely energy-conservation safe heating seat ring.In addition, the part of the hinged cover 55 shown in Fig. 3 and Fig. 4 when heating seat ring (not shown) of the resin of existing general use for be integrally formed with the portion of taking one's seat 24.In the above-described embodiment, the portion of taking one's seat 24 shown in Fig. 3 and Fig. 4 is formed by metal (aluminium), and hinged cover 55 is shaped by acrylic resin.Its reason is, the position of heating by making lamp heater 29 is required Min., reduces the thermal capacity needing heating, thus the portion of taking one's seat 24 can be made more rapidly instantaneously to heat up with less electric power, save electric power further.That is, heat conduction is carried out on the aluminium thermal conductivity highland in portion 24 of taking one's seat, and temperature is become and acts on equably, hinged cover 55 is resin, and the heat in portion 24 of therefore taking one's seat because thermal conductivity is low is absorbed by hinged cover 55 hardly.Like this, by making the parts of the upside of seat ring 22 be made up of multiple parts that thermal conductivity is different, heat can be suppressed not needed the part heated to absorb redundantly, reduce the loss of heat.As mentioned above, be made up of with lower frame body 26 portion of taking one's seat 24 of the upside component parts as seat ring 22 and hinged cover 55, there is inside and have the seat ring 22 of blank part 27, be located at radial pattern heater 29 in blank part 27 and the reflector 28 that be located at lower frame body 26 side relative to this radial pattern heater 29, at least the portion of taking one's seat 24 of upper frame body is made up of metal (aluminium), radiation absorption layer 42 is set by portion of taking one's seat 24 inner face at upper frame body, the energy-conservation transient heating seat ring in the portion 24 that can realize taking one's seat with the more promptly transient heating of less electric power.
In addition, the signal of thermistor 44, room temperature thermistor 48 when control part 50 starts according to energising, calculated by both temperature difference and respective temperature, the optimum value of the energising binding hours of the initial power-up that selection presets, store, reduce turn on angle or be zero when reaching energising binding hours by the elapsed time of timer 49 timing, the signal control turn on angle afterwards based on thermistor 44 makes the portion of taking one's seat 24 of seat ring 22 be heated to preference temperature.
Thus, in fact thermistor 44 detects the temperature near the portion of taking one's seat 24 of user's contact, control part 50 heats up accurately and maintains preference temperature, therefore seat ring 22 can cosily be used, and then based on the signal of thermistor 44 and room temperature thermistor 48, the input amount of emittance is controlled, therefore, it is possible to more high accuracy and be heated to preference temperature safely according to load.
Further, by preferentially carrying out initial power-up time controling, after energising binding hours, turn on angle is reduced, slow down firing rate, even if the response speed of seat ring temperature-detecting device postpones, also can heat seat ring safely, and cheap seat ring temperature-detecting device can be used.Usually, general heater is mostly and applies Control of Voltage temperature by reducing, but lamp heater 29 carries out by circulation the halogen cycle reaction forming tungsten halide with the heating of filament 33, prevents the consumption of filament 33, therefore, when the temperature of glass tube drops to 200 DEG C, halogen cycle reaction is hindered.Therefore, in order to utilize lamp heater 29 to make the portion of taking one's seat 24 rise to preference temperature, in the effective output area of halogen cycle, making power cycles change carry out.
On the other hand, seat ring 22 is in after raised state or male sex user enter lavatory, and when making seat ring 22 be in raised state in order to urine, based on the signal of seat ring position detecting device 47, control part 50 stops being energized to lamp heater 29.Can reduce thus and unnecessarily heat the situation of seat ring 22, realize energy-conservation further, and can prevent in the energized state and on the length direction of the tension direction as filament 34, be subject to Action of Gravity Field and the short-life situation of the contracting such as broken string.
Further, according to the object of user, even if by seat ring 22 opening and closing between the falling of raised state and approximate horizontal state, the lamp heater fixture 36 due to the leaf spring material as elastomeric material relaxes and impacts, therefore, it is possible to prevent glass tube or filament damaged.
Secondly, when user takes one's seat in order to defecation, by the signal of checkout gear 38 of taking one's seat, turn on angle being changed and controls, is zero or amount for seat ring excessive temperature can not be made to raise to make the turn on angle to lamp heater 29.Thus, in use procedure, seat ring temperature can not excessively raise, and does not worry scalding, and can use safely.
Especially, take one's seat because heating seat ring makes direct skin contact be built-in with the seat ring of lamp heater, therefore need to make sufficient consideration to safety.Under common using state, can use on safety and comfort ground as mentioned above, but due to unexpected reason, the control parts 50 such as microcomputer (not shown) break down, and when continuing to be energized to lamp heater 29 etc., also need action safely.
Thermostat usually uses bimetallic 7 to be as shown in Figure 10 enclosed in metal lid 6 and blocks the structure of light, in the structure shown here, first lid 6 is heated, the bimetallic radiation be heated by from lid 6 is carried out, therefore bimetallic reaches predetermined temperature needs spended time, when therefore changing within the temperature short time of seat ring 22, the cut-out of circuit is delayed sometimes.
But in the present embodiment, in order to solve this problem, in thermostat 30, bimetallic 51 exposes, on bimetallic 51 surface, as the blacking of radiation-absorbing material 52 application heat resistance.Therefore, due to the radiant light of the direct receiving light heater 29 of bimetallic 51, therefore the radiant light from lamp heater 29 directly adds thermo bimetal 51, and on the surface of bimetallic 51 as the blacking of radiation-absorbing material 52 application heat resistance, therefore the photothermal major part arriving bimetallic 51 from lamp heater 29 is absorbed by bimetallic 51, promptly can follow the sharply variation of the temperature of seat ring 22, because thermostat 30 is in series electrically connected with lamp heater 29, therefore, when excessive temperature raises, the energising of lamp heater 29 can be cut off.
And then thermostat 30 is set in following position, that is, make the distance a between lamp heater 29 and seat ring 22 surface larger than the distance between lamp heater 29 and thermostat 30.Thus, make the temperature of bimetallic 51 than seat ring 22 surface temperature rise rise soon, therefore when abnormal, can also do not reach seat ring 22 surface temperature excessively raise, be in the precarious positions such as scald time, cut off the power-on circuit of lamp heater 29, ensure safety.
Further, in the present embodiment, if the temperature of bimetallic 51 can be made to raise fast, then the malfunction of thermostat 30 can also be prevented.Namely, if the temperature of bimetallic 51 can be made to raise fast, then the disconnection of thermostat 30 (the power-on circuit open circuit of lamp heater 29) operating temperature can be arranged to the usual serviceability temperature higher than seat ring 22, therefore, thermostat 30 action when can avoid usually using, the danger that the heating function of seat ring 22 cannot use.
That is, Fig. 7 represents in the thermostat 30 of structure shown in Fig. 6, setpoint distance b=7mm, distance a=15mm, measures the result of temperature and portion 24 surface temperature of taking one's seat near bimetallic 51 when being energized to lamp heater 29.In the figure 7, curve (A) is the surface temperature in the portion of taking one's seat 24, when room temperature is 5 DEG C, and about 7.5 seconds (t 1) common seat ring control temperature (T can be warmed up to 1).On the other hand, the temperature of the bimetallic 51 of thermostat 30 is as shown in curve (B), faster than the portion of taking one's seat 24, at t 2time rises to seat ring control temperature (T 1).Portion 24 of taking one's seat reaches the highest design temperature (T of seat ring 22 2) more than time, the temperature of bimetallic 51 reaches disconnection (open circuit) operating temperature (T of thermostat 29 3), cut off the power-on circuit of lamp heater 29.
Further, just in case thermostat 30 breaks down, when becoming the state of the power-on circuit that cannot cut off lamp heater 29, safety margin temperature (T is being reached 4) before, thermostat 31 (or temperature fuse) action of non-restoring type, cuts off the power-on circuit of lamp heater 29.Now, the surface temperature of seat ring 22 can not reach safety margin temperature (T 4).
Further, by the operating temperature (T of thermostat 30 3) be set in the highest design temperature (T of seat ring 22 2) more than and at safety margin temperature (T 4) below, thus, the power-on circuit of the lamp heater 29 that the thermostat 31 (or temperature fuse) also easily eliminating non-restoring type causes cuts off, the danger that the heating function of seat ring 22 cannot use.Namely, the first stage of initial power-up time, timer 49 and the thermistor 44 of control part 50 carry out temperature control, second stage, by thermostat 30 disconnect cut off lamp heater 29 power-on circuit (but due to temperature reduce, circuit can restore), phase III, the power-on circuit (cannot ReSet Circuit) of lamp heater 29 is cut off by the thermostat 31 (or temperature fuse) of non-restoring type, by arranging multilevel security function like this, can use on safety and comfort ground for a long time.
Further, in the present embodiment, as shown in Figure 3, the lamp heater 29 of front side and the lamp heater 29b of rear side are configured in the front and back of seat ring 22, and be provided with many, be oppositely arranged thermostat 30,30b with each lamp heater 29,29b, each thermostat 30,30b are in series electrically connected.In addition, by operating temperature is set to restoring type thermostat 30,30b disconnects action at a lower temperature, non-restoring type thermostat 31,31b disconnect action at the temperature higher than restoring type thermostat 30,30b, realize more much higher heavy security thus, and can use on safety and comfort ground for a long time.
Namely, each lamp heater 29,29b are connected in series with thermostat 30,30b, and then they are connected in series, form the power-on circuit of lamp heater 29,29b, thus no matter when which lamp heater 29,29b produce abnormal, the power-on circuit of thermostat 30,30b cut-out lamp heater 29,29b can be passed through, therefore, it is possible to stop safely to two lamp heaters 29,29b energising.And, thermostat 30,30b use and disconnect the different thermostat of operating temperature, thus, just in case there is problem in one of them thermostat 30, be in cannot cut off lamp heater 29,29b the state of power-on circuit time, also can utilize another thermostat 30b to cut off the power-on circuit of lamp heater 29,29b, because of but safety.And, lamp heater 29,29b are separated into many, therefore, as shown in Figure 9 in the seat ring 2 of existing ring-type, by 1 of ring-type lamp heater 4 is configured in the blank part 1 of seat ring 2 roughly on the whole, directly on lamp heater 4, be applied with stress due to the flexure of seat ring 2 and the step-up error of lamp heater 4 etc., and this problem is eliminated in the present embodiment, the danger of lamp heater 29 breakage that the flexure etc. can eliminating seat ring 22 causes.

In Figure 11 to Figure 15, with the heating seat ring of the warm water cleaning function of cleaning anus after an action of the bowels and private parts, the main body 121 of growing crosswise is arranged on the rearward end of the closet 120 of toilet device, a part for built-in warm water cleaning function in this main body 121, further, be rotatably provided with and be placed on toroidal race 122 on closet 120 and toilet cover 123.Further, be built-in with at the sidepiece of main body 121 human body detection sensor 125 detected with or without human body in lavatory.As shown in figure 11, the portion of taking one's seat 124 formed by aluminium is fixed by encapsulant and is combined on plastic lower frame body 126 and forms seat ring 122, and its inside has the blank part 127 carrying out drip-proof enclosure that can prevent water droplet etc. from immersing.
Inner at blank part 127, the portion of taking one's seat 124 of the seat ring 122 of taking one's seat with the user of use toilet device relatively, be provided with the radiation reflective plate 128 (reflector) that aluminium sheet carried out mirror process and as being in the headlight heater 129 of multiple radial pattern heaters of both sides, the portion of taking one's seat 124, back light heater 129b (after, there is no need to be expressed as lamp heater 129 when distinguishing).Radiation reflective plate 128 as shown in figure 11, the all-round bending part 128a had upward of outer end in it, by this bending part 128a, radiant light from lamp heater 129 is partial to, therefore play the effect improved away from the edge, periphery in the portion of taking one's seat 124 of lamp heater 129 and the radiation density of Inner peripheral portions, the thermal radiation distribution realized to the portion of taking one's seat 124 radiation is even.Near this lamp heater 129, be provided with the rdaiation response type thermostat 130 be in series electrically connected with lamp heater 129, play the effect preventing the excessive temperature in the portion of taking one's seat 124 of seat ring 122 from raising for the unexpected dangerous state of affairs.In addition, radiation reflective plate 128 uses aluminium sheet to realize lightweight, but also can use corrosion resistant plate or steel plating plate etc.
Lamp heater 129 is configured to inactive gas 134 and the micro-halogen gas such as filament 133, argon gas of enclosing tungsten formation in glass tube 132 inside, along with the heating of filament 133, repeatedly carry out the halogen cycle reaction forming tungsten halide, the effect preventing filament 133 from consuming can be played thus.By this effect, using filament 133 very little for thermal capacity as thermal source, the sharply rising of emittance can be carried out.That is, lamp heater 129 is so a kind of radial pattern heater, that is, can enter lavatory from user, take off clothes, and be rapidly heated the portion of taking one's seat 124 of seat ring 122 in the very short time of the such as several seconds till buttocks is seated at the portion of taking one's seat 124 preference temperature.In addition, lamp heater 129, according to the situation of required characteristic, is not necessarily halogen lamp heater.
This lamp heater 129 is fixed on radiation reflective plate 128 by the lamp heater fixture 136 formed by leaf spring material, and radiation reflective plate 128 is fixed in the projection 137 of resinous lower frame body 126 by Screw.
Figure 15 forms the aluminum of seat ring 122 to take one's seat the amplification sectional view of a part in portion 124.In fig .15, the inner surface of blank part 127 side of seat ring 122, the i.e. radiant light of lamp heater 129, be formed with the radiation absorption layer 142 being coated into and can being easy to the black absorbing its radiant light, side of namely taking one's seat, outside forms the corrosion protection aluminium lamination 141 with anticorrosion ability and thereon for obtaining the appearance of hobby and the surface decoration layer 143 of application.In addition, might not need the surface decoration layer 143 simultaneously arranging corrosion protection aluminium lamination 141 and application, any one in the surface decoration layer 143 of corrosion protection aluminium lamination 141 or application can have anticorrosion ability and the designs such as gloss and color such as suitable chemical resistance.But by having the surface decoration layer 143 of corrosion protection aluminium lamination 141 and application, this is two-layer, can have higher anticorrosion ability, and such as by using the coating adding degerming material, can also add bacteria-eliminating efficacy.Further, for the color of radiation absorption layer 142, confirm for shades of colour, consequently, the heat absorption efficiency of black is the highest, can improve the programming rate in the portion of taking one's seat 124.In addition, if be not limited to maximum speed, from practically getting final product this viewpoint, grey or redness, blueness etc. also can heat up.For black, be not limited to application, also can carry out the surface treatments such as dyeing.When aluminium, alumite process etc. are also practical.And, the surface decoration layer 143 that outer surface in the portion of taking one's seat 124 of Figure 15 is implemented also can carry out dyeing process, if but at least implement application on surface, portion of taking one's seat, then not only obtain anticorrosion ability, even the metal back-up thimbles such as aluminium also can be eliminated seem cold sensation, such as by the pearly-lustre application etc. that pearl is such, soft impression or senior impression can be deduced.
The portion of taking one's seat 124 of seat ring 122 uses metal, is specifically punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200W/mK, very more than about 0.1 ~ 1W/mK height of resin, therefore, it is possible to the radiant light of receiving light heater 129, radiation absorption layer 142 heats up, and meanwhile heat can be communicated to outer surface and the surface decoration layer 143 in the portion of taking one's seat 124 fast.Further, owing to being the aluminium that thermal conductivity is higher, therefore, it is possible to obtain Temperature Distribution evenly equal thermal effect.Further, the work hardening by punching press (deep-draw) processing of aluminium, even if thickness of slab is thinner, also can guarantee necessary intensity.Such as, when resin, from the angle of intensity, need the wall thickness of about 3mm, if the deep-draw processed goods of aluminium sheet, then below the 1.5mm of a half thickness is namely enough.Due to thinner, thermal capacity is less, and therefore heat up required heat and time can reduce.From experimental result, intensity and the angle of heating-up time, the thickness of slab obtaining aluminium sheet is preferably the conclusion of 0.8 ~ 1.2mm.
And, form in the lower frame body 126 of seat ring 122, radiant light reflecting plate 128 is installed on the surface within it, on this radiant light reflecting plate 128, the rdaiation response type thermostat 130, the heat-conducting type thermostat 131 that are connected in series with headlight heater 129 and back light heater 129b is installed.Further, aluminum is installed on lower frame body 126 top and takes one's seat portion 124, to take one's seat the temperature in portion 124 to detect this aluminum, the inner surface in the portion of taking one's seat 124 is provided with the thermistor 144 as seat ring temperature-detecting device.And, seat ring 122, its rotating shaft 145 forms electrode 146, seat ring position detecting device 147 is formed in the lump with the bearing portion (not shown) of main body 121, detect seat ring 122 and be positioned at raised state, or be positioned at the approximate horizontal use location on closet 120 can taken one's seat and use.
Main body 121 is provided with the control part 150 based on microcomputer, the go forward side by side temperature of portable lighter heater 129 of this control part 150 detection signal be taken into as the room temperature thermistor 148 of room temperature detector controls, and there is timing unit 149, this timing unit 149 starts elapsed time to the moment of heating up from by being energized to the lamp heater 129 of seat ring 122 and carries out timing.And, control part 150 is taken into detection people and enters indoor human body detection sensor 125 or the signal of take one's seat checkout gear 138 and seat ring position detecting device 147, control the start and stop be energized to lamp heater 129, and the signal be taken into from thermistor 144, room temperature thermistor 148, temperature control is carried out to lamp heater 129, reaches predetermined temperature as preference temperature to make the temperature as the portion of taking one's seat 124 in heating face.
In figure 16, rdaiation response type thermostat 130 is configured to expose in blank part 127 to make the radiant light of bimetallic 151 receiving light heater 129, and lamp heater 129 and bimetallic 151 are oppositely arranged.Further, the light receiving surface of bimetallic 151 is coated with the heat resistance blacking as radiant heat absorbent material 152.And rdaiation response type thermostat 130 is configured to effectively be absorbed from radial pattern heater to the heat of bimetallic 151 radiation by radiant heat absorbent material 152, more promptly improves bimetallic temperature.Further, rdaiation response type thermostat 130 is set as making the distance a between lamp heater 129 and the portion of taking one's seat 124 of seat ring 122 to be greater than distance b between lamp heater 129 and bimetallic 151.This distance a is the distance to the radiation absorption layer 142 as sensitive surface on the inner surface being located at the portion of taking one's seat 124 in the present embodiment.
In figure 18, heat-conducting type thermostat 131, has lid 154 to make the radiant light of bimetallic 151 direct receiving light heater 129 before bimetallic 151, and relatively with lamp heater 129 sets.Lid 154 is formed by the metal that thermal conductivity is good, is in this case formed by aluminium alloy, and its surface is provided with the radiant heat absorbent material that blacking is formed.
Rdaiation response type thermostat 130 and heat-conducting type thermostat 131 and two lamp heaters 129,129b are connected in series.
In the above-described embodiment, when user enters lavatory, human body detection sensor 125 detects that it enters, and this signal is sent to control part 150.Now, when confirming that seat ring 122 is in approximate horizontal use location by the signal of seat ring position detecting device 147, control part 150 starts the energising to lamp heater 129.By this initial power-up, drop into energy and be transformed to emittance instantaneously, emitted to the direction, portion of taking one's seat 124 of seat ring 122 by filament 133 through glass tube 132 and radiant light reflecting plate 128.And then the emittance of lamp heater 129 makes the radiation absorption layer 142 of the inner surface in the portion of taking one's seat 124 being located at seat ring 122 and portion 124 of taking one's seat heat up.Like this, in the present embodiment, after user enters lavatory, can be energized to lamp heater 129, the almost heating face in the portion of taking one's seat 124 of transient heating seat ring 122, even and if for the dangerous state of affairs that the accident that the fault etc. of control part 150 causes occurs, by by the radiant light of bimetallic 151 receiving light heater 129 and the rdaiation response type thermostat 130 of fast response can cut off the energising of lamp heater 129, therefore be energized all the time with the existing heating seat ring used in general manner and be incubated, the situation that heat release loss is very large is different, achieve and almost there is no heat release loss, the extremely energy-conservation and heating seat ring of safety.In addition, the part of the hinged cover 156 shown in Figure 13 and Figure 14 when heating seat ring (not shown) of the existing resin used in general manner for be integrally formed with the portion of taking one's seat 124.In the above-described embodiment, the portion of taking one's seat 124 shown in Figure 13 and Figure 14 is formed by metal (aluminium), and hinged cover 156 is formed by acrylic resin.Its reason is, the position of heating by making lamp heater 129 is required Min., reduces the thermal capacity needing heating, thus can with less electric power more rapidly transient heating to take one's seat portion 124, save electric power further.That is, the aluminium thermal conductivity in portion 124 of taking one's seat carries out heat conduction higher, the effect of homogeneous temperature ground, and hinged cover 156 is resin, and the heat in portion 124 of therefore taking one's seat because thermal conductivity is low is absorbed by hinged cover 156 hardly.Like this, by making the parts of the upside of seat ring 122 be made up of multiple parts that thermal conductivity is different, heat can be suppressed not needed the part heated to absorb redundantly, reduce the loss of heat.As mentioned above, owing to being provided with: be made up of with lower frame body 126 portion of taking one's seat 124 of the upside component parts as seat ring 122 and hinged cover 156, and there is in inside the seat ring 122 of blank part 127, be located at the radial pattern heater 129 in blank part 127, and the reflector 128 that be located at lower frame body 126 side relative to this radial pattern heater 129, and at least the portion of taking one's seat 124 of upper frame body is made up of metal (aluminium), at portion of taking one's seat 124 inner face of upper frame body, radiation absorption layer 142 is set, thus the energy-conservation transient heating seat ring more promptly making the portion of taking one's seat 124 heat up instantaneously with less electric power can be realized.
In addition, the signal of thermistor 144, room temperature thermistor 148 when control part 150 starts according to energising, calculated by both temperature difference and respective temperature, the optimum value of the energising binding hours of the initial power-up that selection presets, store, reduce turn on angle or be zero when reaching energising binding hours by the elapsed time of timer 149 timing, the signal control turn on angle afterwards based on thermistor 144 makes the portion of taking one's seat 124 of seat ring 122 arrive preference temperature.
Thus, in fact thermistor 144 detects the temperature near the portion of taking one's seat 124 of user's contact, control part 150 heats up accurately and maintains preference temperature, therefore seat ring 122 can cosily be used, and then based on the signal of thermistor 144 and room temperature thermistor 148, the input amount of emittance is controlled, therefore, it is possible to more high accuracy and be heated to preference temperature safely according to load.
Further, by preferentially carrying out initial power-up time controling, after energising binding hours, turn on angle is reduced, slow down firing rate, even if the response speed of seat ring temperature-detecting device postpones, also can heat seat ring safely, and cheap seat ring temperature-detecting device can be used.Usually, general heater is mostly and applies Control of Voltage temperature by reducing, but lamp heater 129 carries out by circulation the halogen cycle reaction forming tungsten halide with the heating of filament 133, prevents the consumption of filament 133, therefore, when the temperature of glass tube drops to 200 DEG C, halogen cycle reaction is hindered.Therefore, in order to utilize lamp heater 129 to make the portion of taking one's seat 124 rise to preference temperature, in the effective output area of halogen cycle, making power cycles change carry out.
On the other hand, seat ring 122 is in after raised state or male sex user enter lavatory, and when making seat ring 122 be in raised state in order to urine, based on the signal of seat ring position detecting device 147, control part 150 stops being energized to lamp heater 129.Can reduce thus and unnecessarily heat the situation of seat ring 122, realize energy-conservation further, and can prevent in the energized state and be subject to Action of Gravity Field and the short-life situation of the contracting such as broken string at the length direction of the tension direction as filament 133.
And, according to the object of user, even if by seat ring 122 opening and closing between the falling of raised state and approximate horizontal state, the lamp heater fixture 136 as the leaf spring material of elastomeric material also can relax impact, therefore, it is possible to prevent glass tube or filament damaged.
Secondly, when user takes one's seat in order to defecation, by the signal of checkout gear 138 of taking one's seat, turn on angle being changed and controls, is zero or amount for seat ring excessive temperature can not be made to raise to make the turn on angle to lamp heater 129.Thus, in use procedure, seat ring temperature can not excessively raise, and does not worry scalding, and can use safely.
Especially, take one's seat because heating seat ring makes direct skin contact be built-in with the seat ring of lamp heater, therefore need to make sufficient consideration to safety.Under common using state, can use on safety and comfort ground as mentioned above, but due to unexpected reason, the control parts 150 such as microcomputer (not shown) break down, and when continuing to be energized to lamp heater 129 etc., also need safety device reliably action.Situation about raising as seat ring excessive temperature in use considers following situation.Namely the control part 150 such as microcomputer (not shown) breaks down, when continuing to be energized to lamp heater 129 and thermistor 144 break down, situation when seat ring temperature rises gradually.
Thermostat usually uses bimetallic 7 to be as shown in Figure 10 enclosed in metal lid 6 and blocks the structure of light, in the structure shown here, first lid 6 is heated, the bimetallic radiation be heated by from lid is carried out, therefore bimetallic reaches predetermined temperature needs spended time, when the variations in temperature of therefore seat ring 122 at short notice, the cut-out of circuit is delayed sometimes.In the present embodiment, in order to solve this problem, corresponding with many lamp heaters 129 rdaiation response type thermostat 130 and heat-conducting type thermostat 131 are set, and they are connected in series.
First, rdaiation response type thermostat is described.Rdaiation response type thermostat 130 exposes bimetallic 151, as the blacking of radiant heat absorbent material 152 application heat resistance on the surface of bimetallic 151.Therefore, due to the radiant light of the direct receiving light heater 129 of bimetallic 151, therefore the radiant light from lamp heater 129 directly adds thermo bimetal 151, and the surface due to bimetallic 151 is coated with the blacking of the heat resistance as radiant heat absorbent material 152, therefore from lamp heater 129 arrive bimetallic 151 radiant heat major part absorbed by bimetallic 151, promptly can follow the sharply change of the temperature of seat ring 122, because rdaiation response type thermostat 130 is in series electrically connected with lamp heater 129, therefore the energising of lamp heater 129 can be cut off when excessive temperature raises.
And then rdaiation response type thermostat 130 is set as, make the distance a between lamp heater 129 and seat ring 122 surface larger than the distance b between lamp heater 129 and rdaiation response type thermostat 130.Thus, make the temperature of bimetallic 151 than seat ring 122 surface temperature rise rise soon, therefore when abnormal, can also do not reach seat ring 122 surface temperature excessively raise, be in the precarious positions such as scald time, cut off the power-on circuit of lamp heater 129, because of but safety.
Further, in the present embodiment, if the temperature of bimetallic 151 can be made to raise fast, then the malfunction of rdaiation response type thermostat 130 can also be prevented.Namely, if the temperature of bimetallic 151 can be made to raise fast, then the disconnection of rdaiation response type thermostat 130 (power-on circuit of lamp heater 129 disconnects) operating temperature can be arranged to the usual serviceability temperature higher than seat ring 122, therefore, when can avoid usually using, rdaiation response type thermostat 130 works, the danger that the heating function of seat ring cannot use.
That is, Figure 18 represents setpoint distance b=7mm, distance a=15mm in the thermostat 31 of structure shown in Figure 16, measures the result of temperature and portion 124 surface temperature of taking one's seat near bimetallic 151 when being energized to lamp heater 129.In figure 18, curve (A) is the surface temperature in the portion of taking one's seat 124, when room temperature is 5 DEG C, and about 7.5 seconds (t 1) common seat ring control temperature (T can be warmed up to 1).On the other hand, the temperature of the bimetallic 151 of rdaiation response type thermostat 130 is as shown in curve (B), faster than the portion of taking one's seat 124, at t 2time rises to seat ring control temperature (T 1).Portion 124 of taking one's seat reaches the highest design temperature (T of seat ring 122 2) more than time, the temperature of bimetallic 151 reaches disconnection (open circuit) operating temperature (T of rdaiation response type thermostat 130 3), cut off the power-on circuit of lamp heater 129.
Therefore, break down at microcomputer etc., under the state being in the power-on circuit that cannot cut off lamp heater 129, before reaching safety margin temperature, the action of rdaiation response type thermostat 130, cuts off the power-on circuit of lamp heater 129.Now, the surface temperature of seat ring 122 does not reach safety margin temperature (T 4).Further, because rdaiation response type thermostat 130 is non-restoring type, therefore during 130 action of rdaiation response type thermostat, later seat ring temperature would not excessively raise.
Then, heat-conducting type thermostat 131 is described.Heat-conducting type thermostat 131 is as shown in figure 17, identical with the structure of the existing thermostat 5 represented in Fig. 10, and bimetallic 151 is enclosed in the lid 154 of metal, cuts off the radiant light from lamp heater 129.In the structure shown here, first lid 154 is heated, and by carrying out from the heat conduction of lid 154 and radiation, therefore to bimetallic reaches predetermined temperature, needs spended time.But user sits on seat ring 122, when lamp heater 122 is in keeping warm mode with low output, heat-conducting type thermostat 131 and seat ring temperature are roughly the same temperature.
Figure 19 represents that thermistor 144 breaks down, and accurately cannot detect the temperature of seat ring 122, the temperature (curve D) of the temperature (curve C) of seat ring 122 and the bimetallic 151 of heat-conducting type thermostat 131 when seat ring temperature rises gradually.Seat ring temperature rises gradually, but the temperature of bimetallic 151 rises similarly, and portion 124 of taking one's seat becomes the highest design temperature (T of seat ring 122 2) more than, and then the temperature of bimetallic 151 reaches disconnection (open circuit) operating temperature (T of heat-conducting type thermostat 131 5) time, cut off the power-on circuit of lamp heater 129.The temperature of bimetallic 151 and seat ring 122 is roughly equal, therefore reaches safety margin temperature (T at seat ring 4) before cut off the power-on circuit of lamp heater 129 effectively.
Disconnection operating temperature (the T of heat-conducting type thermostat 131 5) than the disconnection operating temperature (T of rdaiation response type thermostat 130 3) low, therefore consider such as different according to environment for use, the situation of action when seat ring does not have an exception.Therefore, heat-conducting type thermostat 131 is restoring type, at bimetallic 151 than disconnecting operating temperature (T 5) restore at low temperature, can reuse.
Further, rdaiation response type thermostat 130 is reached the highest design temperature (T of seat ring 122 in seat ring surface temperature 2) more than and at safety margin temperature (T 4) below carry out disconnection action, but in fact, the disconnection operating temperature (T of rdaiation response type thermostat 130 3) safety margin temperature (T than seat ring can be set in 4) high temperature, because this eliminating the power-on circuit of rdaiation response type thermostat 130 turn-off lamp heater 129 easily, the danger that the heating function of seat ring 122 cannot use.Namely, the first stage of initial power-up time, timing unit 149 and the thermistor 144 of control part 150 carry out temperature control, second stage, by heat-conducting type thermostat 131 disconnect cut off lamp heater 129 power-on circuit (but due to temperature reduce, circuit can restore), phase III, the power-on circuit (cannot ReSet Circuit) of lamp heater 129 is cut off by the rdaiation response type thermostat 130 of non-restoring type, by arranging multilevel security function like this, can use on safety and comfort ground for a long time.
Namely, as shown in figure 13, the lamp heater 129 of front side and the lamp heater 129b of rear side are configured in the front and back of seat ring 122, and be provided with many, be oppositely arranged rdaiation response type thermostat 130,130b and heat-conducting type thermostat 131,131b with each lamp heater 129,129b, be in series electrically connected respectively.In addition, the heat-conducting type thermostat 131 of restoring type, 131b disconnect action at a lower temperature, non-restoring type thermostat 130,130b disconnect action at the temperature higher than the heat-conducting type thermostat 131 of restoring type, 131b, realize more much higher heavy security thus, and can use on safety and comfort ground for a long time.
In addition, in the present embodiment, the thermostat of rdaiation response type and heat-conducting type is oppositely arranged with each lamp heater, when having multiple lamp heater, on optional position in a series of lamp heater, be oppositely arranged each thermostat, can same safe action be carried out thus.Further, if having multiple thermostat of the same race, even if one then in thermostat of the same race produces abnormal, other thermostats can also carry out safe action effectively.
And, lamp heater 129,129b are divided into many, therefore, in existing colyliform seat ring 2 shown in Fig. 9,1 of ring-type lamp heater 4 is configured in the blank part 1 of seat ring 2 roughly on the whole, thus the problem directly being applied stress by the flexure of seat ring 2 and the step-up error of lamp heater 4 etc. on lamp heater 4 is eliminated, the danger of lamp heater 129 breakage that the flexure etc. can eliminating seat ring 122 causes.
(embodiment 4)
Figure 20 is the partial cross section figure of the main portion sectional view, particularly thermostat of heating seat ring in embodiments of the present invention 4.Present embodiment is substantially identical with the structure of the invention of embodiment 3, and difference is to improve the structure of the thermostat be connected in series with lamp heater, is therefore only described the structure of different thermostats.
In figure 18, the lid 153 of rdaiation response type thermostat 130c is formed by clear glass, with the radiant light making bimetallic 151 receive lamp heater 129.In addition, by arranging the lid 153 of clear glass, antidrip or water proof type that water droplet or dust can not invade rdaiation response type thermostat 130c inside can be set as, just in case in blank part 127 during water inlet, also can invade to the conducting parts of rdaiation response type thermostat 130c by anti-sealing, can electric insulation be maintained, prevent from getting an electric shock.Further, similarly, the blacking of application heat resistance on the light receiving surface of bimetallic 151, as radiant heat absorbent material 152 for rdaiation response type thermostat 130c and Figure 16.Further, rdaiation response type thermostat 130c absorbs the heat from radial pattern heater to bimetallic 151 radiation effectively by radiant heat absorbent material 152, can improve bi-metal temperature more quickly.Further, the rdaiation response type thermostat 130c distance a be configured between lamp heater 129 and seat ring 122 surface is greater than the distance b between lamp heater 129 and bimetallic 151.Therefore, due to the radiant light of the direct receiving light heater 129 of bimetallic 151, therefore the radiant light from lamp heater 129 directly adds thermo bimetal 151, and owing to scribbling the blacking of heat resistance as radiant heat absorbent material 152 on bimetallic 151 surface, therefore from lamp heater 129 arrive bimetallic 151 radiant heat major part absorbed by bimetallic 151, the sharply variation of the temperature of seat ring 122 can be followed, rdaiation response type thermostat 130 is in series electrically connected with lamp heater 129, therefore, when excessive temperature raises, the energising of lamp heater 129 can be cut off.
In addition, the clear glass of lid 153 uses quartz glass, and therefore the transmissison characteristic of the radiant energy light of lamp heater 129 is excellent, and response is quicker, improves seperating safety.Certainly, also other glass can be used as required.Further, when the thickness of slab of clear glass 153 is blocked up, transmission performance reduces, and therefore preferably thickness of slab is below 1.5mm, is more preferably below 1.2mm.Further, in the respective embodiments described above, the material in portion of taking one's seat is the punch process product of aluminium sheet, but other processing methods such as cast aluminium also can obtain same effect.The kind of metal also can be copper coin or steel plate.
(embodiment 5)
In Figure 21 to Figure 25, the seat ring being arranged on the present embodiment on the closet 20 of toilet device is made up of fell seat ring main body 203 that ground pivot arranges and lid 204 of the main body 202 of growing crosswise and can freely standing up before it.
In described main body 202, be built-in with a part for warm water cleaning function, and in be provided with various controlling functions.Further, with this main body 202 one or independently arrange human body detection sensor 205, detect that people enters indoor, lavatory, open lid 204, or make the various controlling functions startings of main body 202.
But described seat ring main body 203 is formed by using lower part: the synthetic resin lower frame body 207 given prominence to from both sides, rear as the leg 206 of the pivot setting unit of opposing body 202; Engaged by encapsulant and this lower frame body 207 watertight, in the portion of taking one's seat 209 that the Heat Conduction Material such as aluminium of Inner Constitution blank part 208 is formed.
Be provided with in blank part 208: radiation heater 210 before and after 2 that configure roughly annularly, and be positioned at the back of these radial pattern heaters 210, be namely positioned at the reflecting plate 211 of lower frame body 207 side.
Front and back radial pattern heater 210 is in series electrically connected, respectively inactive gas such as being mixed into the argon gas of micro-halogen is enclosed the heat penetration be made up of sintered glass ceramics etc. and cross pipe 212 inside, wherein configure the filaments 213 such as tungsten, along with the heating of this filament 213, repeatedly carry out the halogen cycle reaction forming tungsten halide, prevent the consumption of described filament 213 thus.
By described effect, filament 213 very little for thermal capacity can be carried out the sharply rising of emittance as thermal source.I.e. radial pattern heater 210, enters lavatory user, in time moment of such as several seconds the portion of taking one's seat 208 of seat ring main body 203 of taking one's seat, and portion 208 of this being taken one's seat is rapidly heated preference temperature.
In addition, radial pattern heater 210, according to the situation of required characteristic, does not necessarily use halogen.
If lightweight paid attention to by reflecting plate 211, expect to use aluminium sheet, if not so, also can use corrosion resistant plate or steel plating plate etc.As shown in figure 21, within it the all-round of outer end has to bending part 211a upward, and by this bending part 211a, the radiant heat from radial pattern heater 210 is partial to, and effectively and equably heating is taken one's seat portion 209.
Further, described reflecting plate 211 is fixed in projection 214 that lower frame body 207 is formed by Screw etc., and according to the height of this projection 214, setting between plays the gap of heat-blocking action.
The fixture 215 of the leaf spring material that radial pattern heater 210 is fixed on reflecting plate 211 by methods such as welding by lower end keeps.More particularly, as shown in figure 25, described fixture 215 by the outer peripheral face of the free end side arc sections clamping radial pattern heater 210 of a pair holding piece 215a, 215b, and lockingly on its free end has clamping plate 216, prevents accidentally expanding of described holding piece 215a, 215b thus.
Clamping plate 216 are for can freely dismantle, and when being pulled down, nature at random can carry out radial pattern heater 210 relative to the installation of holding piece 215a, 215b, dismounting.
As shown in figure 26, in the inner surface side in the portion of taking one's seat 209, namely on the position that the radiant heat of radial pattern heater 210 irradiates, in order to absorb its radiant heat preferably, be formed with black and the radiant heat absorbent layer 217 of electrical insulating property, in outside, side of namely taking one's seat is provided with the surface decoration layer 219 of the lumariths 218 such as corrosion protection aluminium lamination and the application in order to the appearance of liking thereon.
In addition, not necessarily both lumarith 218 and surface decoration layer 219, only has any one, can both have anticorrosion ability and the designs such as gloss and color such as suitable chemical resistance.
But, by having both lumarith 218 and surface decoration layer 219, higher anticorrosion ability can be obtained, and such as by using the coating adding degerming material, also can add bacteria-eliminating efficacy.
Further, for the color of radiant heat absorbent layer 217, to shades of colour confirm as a result, the heat absorption efficiency of black is the highest, the programming rate in the portion of taking one's seat 209 can be improved.
If be not limited to maximum speed, from practically getting final product this viewpoint, grey or redness, blueness etc. also can heat up.
When described portion 209 of taking one's seat uses punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200W/mK, very more than about 0.1 ~ 1W/mK height of resin, therefore, it is possible to the radiant heat of receiver radiation type heater 210, radiant heat absorbent layer 217 heats up, and meanwhile heat can be communicated to the surface decoration layer 219 in the portion of taking one's seat 209 fast.Further, owing to being the aluminium that thermal conductivity is higher, therefore, it is possible to obtain Temperature Distribution evenly equal thermal effect.Further, the work hardening by punching press (deep-draw) processing of aluminium, even if thickness of slab is thinner, also can guarantee necessary intensity.
Such as, when resin, from the angle of intensity, need the wall thickness of about 3mm, if the punch process product of aluminium sheet, then below the 1.5mm of a half thickness is namely enough.Due to thinner, thermal capacity is less, and therefore heat up required heat and time can reduce.
From experimental result, intensity and the angle of heating-up time, the thickness of slab obtaining aluminium sheet is preferably the conclusion of 0.8 ~ 1.2mm.
Each radial pattern heater 210 both sides in front and back, in series each 2 thermostats 220 of electrical connection configuration, and then, in the portion of taking one's seat 209, each 1 is provided with accordingly with its sidepiece, amount to the temperature sensor 221 that 2 thermistors are such, play for the unexpected dangerous state of affairs, prevent the effect that the excessive temperature in the portion of taking one's seat 209 raises.
First, thermostat 220 as shown in figure 27, adopts and is configured in box 223 bimetallic 222 to make the structure of the radiant heat direct irradiation from radial pattern heater 210.Described bimetallic 222 is disk spring shape parts, take stop as border, is alternatively inverted to 2 settling positions according to temperature.
Further, the blacking of application heat resistance on the radiant heat heating surface of this bimetallic 222, etc., form radiant heat absorbent layer 224, absorb the radiant heat from radial pattern heater 210 efficiently, temperature can be improved more quickly.
Further, thermostat 220 is set to, make the distance b between radial pattern heater 210 and bimetallic 222 than radial pattern heater 210 and the distance a that takes one's seat between portion 209 little.Further, the distance till this distance a represents on the inner surface being located at the portion of taking one's seat 209 radiation absorption layer 217 in the present embodiment.
In order to guarantee the distance b of predetermined value between described radial pattern heater 210 and bimetallic 222, from by thermostat 220, the fixing body 225 be installed to reflecting plate 211 is provided with the dividing plate 226 shown in Figure 28 integratedly.That is, the circumference wall of the arc-shaped recess and radial pattern heater 210 that are formed in the front end of this dividing plate 226 fastens, and determines distance b.
Main body 202 is provided with the control part 229 based on microcomputer, this control part 229 is taken into the detection signal as the temperature sensor 227 of room temperature detector and carries out the energising control of radial pattern heater 210, and carries out timing by the energising elapsed time of timing unit 228 subtend radiation heater 210 energising.
And, control part 229 is taken into described human body detection sensor 205 or detects the signal that user sits in take one's seat checkout gear 230 and the seat ring position detecting device 231 in the portion of taking one's seat 209, control the start and stop be energized to radial pattern heater 210, and be taken into Autonomous test and take one's seat 2 temperature sensors 221 of temperature in portion 209 and the signal of described temperature sensor 227, temperature control is carried out to radiativity heater 210, reaches predetermined value as preference temperature to make the temperature as the portion of taking one's seat 209 in heating face.
Further, what this control part 229 also carried out the displays 232 such as indicator lamp lights control, and taking one's seat when portion 209 does not reach predetermined temperature to radial pattern heater 210 energising in beginning is in blink states, is in continuous illuminating state when reaching predetermined temperature.
This display 232 is configured in the position that any state that no matter lid 204 is in opening and closing can both confirm, the positions such as the front upper surface of such as main body 202.
And then, as the parts of temperature detecting portion 209 of taking one's seat, be provided with 2 temperature sensors 221, but control part 229 carries out radial pattern heater 210 temperature when the temperature detection result of these temperature sensors 221 does not have deviation controls, when producing the deviation of more than preset range, stop being energized to radial pattern heater 210.
This is due to contrary with the homogeneous heating object in the portion of taking one's seat 209, if there is predetermined above temperature deviation, can envision the problem in safety.
In the above-described embodiment, when user enters lavatory, human body detection sensor 205 detects this situation, sends signal to control part 229.Now, by the signal of seat ring position detecting device 231, when confirming that seat ring main body 203 is positioned at approximate horizontal use location, control part 229 starts the energising of radial pattern heater 210.
By this initial power-up, drop into energy and convert radiant heat to instantaneously, the direction to the portion of taking one's seat of seat ring main body 203 is directly radiated and radiation after reflection on reflecting plate 211.
The radiant heat radiated to the direction in described portion 209 of taking one's seat is absorbed efficiently by radiation absorption layer 217, and the portion of taking one's seat 209 can be rapidly heated by its result.
Like this, in the present embodiment, when user enters lavatory, be energized to radial pattern heater 210, the almost portion of taking one's seat 209 of transient heating seat ring main body 203, even and if during the unexpected dangerous state of affairs that the fault etc. of control part 229 is caused, the radiant heat of the direct receiver radiation heater 210 of the bimetallic 222 due to thermostat 220, therefore, it is possible to fast to its response, cut off energising, therefore, like that all the time, be energized with the heating seat ring of existing general use and be incubated, the larger situation of heat release loss is compared, can realize almost not having heat release to lose, the very energy-conservation and heating seat ring of safety.
And, in seat ring main body 203, lower frame body 207 is formed by synthetic resin, and it is one-body molded with this lower frame body 207 as the leg 206 of the pivot setting unit of opposing body 202, therefore the position that radial pattern heater 210 heats is restricted to Min. needed for portion of only taking one's seat 209, and suppress heat to be escaped via leg 206 as much as possible, therefore, it is possible to less electric power portion 209 of taking one's seat fast is utilized to heat up.
And then, temperature sensor 221 when control part 229 starts based on energising and the signal of temperature sensor 227, computing is carried out according to the two temperature difference or respective temperature, the optimum value of the energising binding hours of the initial power-up that selection presets, store, when arriving energising binding hours by the elapsed time of timing unit 228 timing, reduce turn on angle or be zero, the signal thereafter based on thermistor 244 controls turn on angle, becomes preference temperature to make the portion of taking one's seat 209.
Thus, temperature sensor 221 detects the temperature near the portion of taking one's seat 209 of the actual contact of user, heat up well by control part 229 precision and maintain room temperature, therefore cosily seat ring can be used, and, based on the signal of temperature sensor 221 and temperature sensor 227, control the input amount of emittance according to load, therefore, it is possible to high accuracy and be heated to preference temperature safely.
Further, by preferentially carrying out initial power-up time controling, after energising binding hours, reduce turn on angle, reduce programming rate, even if therefore the response speed of seat ring temperature-detecting device is slower, also safely seat ring can be heated, and cheap seat ring temperature-detecting device can be used.
Usually, general heater carrys out control temperature by reducing applying voltage mostly, but the radial pattern heater 210 of halogen is by repeatedly carrying out the halogen cycle reaction forming tungsten halide along with the heating of filament 213, the consumption of filament 213 can be prevented thus, therefore, when the temperature that heat penetration crosses pipe 212 becomes below 200 DEG C, halogen cycle is hindered.Therefore, in order to utilize radial pattern heater 210 portion 209 of taking one's seat to be set to preference temperature, in the effective output area of halogen cycle, making power cycles change carry out.
On the other hand, seat ring main body 203 is in after raised state or male sex user enter lavatory, when making seat ring main body 203 be in raised state in order to urine, based on the signal of seat ring position detecting device 231, control part 229 stops being energized to radial pattern heater 210.The situation unnecessarily heating seat ring main body 203 can be reduced thus, realize energy-conservation further, and can prevent in the energized state and be subject to Action of Gravity Field and the situation of the reductions of service life such as broken string at the length direction of the tension direction as filament 213.
And; according to the object of user, even if by seat ring main body 203 opening and closing between the falling of raised state and approximate horizontal state, the fixture 215 of leaf spring material keeps radial pattern heater 210; realize surge protection, therefore, it is possible to prevent heat penetration from crossing pipe 212 or filament 213 breakage.
Secondly, when user takes one's seat in order to defecation, by the signal of checkout gear 230 of taking one's seat, turn on angle being changed and controls, is zero or amount for seat ring excessive temperature can not be made to raise to make the turn on angle to radiation heater 210.Thus, in use procedure, seat ring temperature can not excessively raise, and does not worry scalding, and can use safely.
Especially, because heating seat ring makes direct skin contact heat seat ring 209, therefore need to make sufficient consideration to safety.Under common using state, can use on safety and comfort ground as mentioned above, but due to unexpected reason, the control parts 229 such as microcomputer (not shown) break down, and when continuing to be energized to radial pattern heater 210 etc., also need action safely.
Thermostat uses bimetallic to be enclosed in the structure of radiation-inhibiting heat in metal lid usually.In the structure shown here, first lid is heated, and the bimetallic radiation be heated by from lid is carried out, therefore until bimetallic reaches predetermined temperature need spended time, when the variations in temperature of therefore seat ring at short notice, the cut-out of circuit is delayed sometimes.
Further, in the present embodiment, in order to solve this problem, thermostat 220 makes its bimetallic 222 directly be heated, and has the blacking of heat resistance as radiant heat absorbent layer 224 at external coating.
Therefore, the photothermal major part arriving bimetallic 222 from radial pattern heater 210 is absorbed by this bimetallic 222, can follow the sharply variation of the temperature in the portion of taking one's seat 209 fast, can cut off the energising of radial pattern heater 210 when excessive temperature raises immediately.
And then, the position of setting thermostat 220, in more detail, be set to distance b between its bimetallic 222 and radial pattern heater 210 than radial pattern heater 210 and the distance a that takes one's seat between portion 209 short, thus, make the take one's seat surface temperature in portion 209 of the temperature-rise ratio of bimetallic 222 rise fast, carry out safe action during exception effectively.
Like this, if the temperature of bimetallic 222 can be made to rise quickly, the malfunction of thermostat 220 can also be prevented.Namely, if the temperature of bimetallic 222 can be made to raise fast, then the disconnection of thermostat 220 (power-on circuit disconnection) operating temperature can be arranged to the usual serviceability temperature higher than seat ring, therefore, thermostat 220 action when can avoid usually using, the danger that heating function cannot use.
That is, Figure 29 represents setpoint distance b=7mm, distance a=15mm in the thermostat 220 of structure shown in Figure 27, temperature and the result of portion 209 surface temperature of taking one's seat near bimetallic 222 when measuring radiation type heater 210 is energized.
In Figure 28, curve (A) is the surface temperature in the portion of taking one's seat 209, and when room temperature is 5 DEG C, about 7.5 seconds (t1) can be warmed up to common seat ring control temperature (T1).On the other hand, the temperature of the bimetallic 222 of thermostat 220 is as shown in curve (B), faster than the portion of taking one's seat 209, rises to seat ring control temperature (T1) in the t2 time.Take one's seat portion 209 when reaching more than the highest design temperature (T2) of seat ring, and the temperature of bimetallic 222 reaches the disconnection operating temperature (T3) of thermostat 220, cuts off the power-on circuit of radiation heater 210.
As mentioned above, the distance b between thermostat 220 and radial pattern heater 210 is significant in safety, therefore its size management expectancy high accuracy.
Therefore, as shown in figure 28, from the fixing body 225 be installed to reflecting plate 211 is provided with dividing plate 226 integratedly by thermostat 220, the arc-shaped recess of the front end being formed in this dividing plate 226 and the circumference wall of radial pattern heater 210 are fastened.Thus, the distance b between thermostat 220 and radial pattern heater 210 is accurate, can carry out described safe action effectively.
In addition, in the present embodiment, the part in multiple thermostats 220 of configuration (being such as configured in 2 on the right side of Figure 23) is made to be restoring type, all the other (being such as configured in 2 on the left of Figure 23) are non-restoring type, just in case restoring type thermostat 220 breaks down, when becoming the state of the power-on circuit that cannot cut off radial pattern heater 210, before reaching safety margin temperature (T4), thermostat 220 action of non-restoring type, cuts off power-on circuit.Consequently, raceway surfaces temperature can not reach safety margin temperature (T4).
And, the operating temperature (T3) of thermostat 220 is set in more than the highest design temperature (T2) of seat ring and in safety margin temperature (T4) below, thus, the thermostat 220 eliminating non-restoring type cuts off the power-on circuit of radial pattern heater 210, the problem that the heating function of seat ring cannot use.
Namely, the first stage of initial power-up time, timer 228 and the temperature sensor 221 of control part 229 carry out temperature control, second stage, disconnects the power-on circuit (but due to temperature reduction, circuit can restore) cutting off radial pattern heater 210 by thermostat 220, phase III, cutting off power-on circuit (cannot ReSet Circuit) by the thermostat 220 of non-restoring type, by arranging multilevel security function like this, can use on safety and comfort ground for a long time.
In addition, by being set to following operating temperature, namely, restoring type thermostat 220 is made to carry out disconnection action in slightly low temperature, non-restoring type thermostat 220 carries out disconnection action at the temperature higher than it, can arrange more much higher level security performance, can safely and cosily use.
Further, multiple radial pattern heater 210 forms heating source, and the problem therefore directly applying stress due to the flexure of seat ring main body 203 and the step-up error of radial pattern heater 210 etc. on this radial pattern heater 210 is eliminated, and can eliminate damaged danger.Certainly, the configuration of radial pattern heater 210 itself also becomes simple.
Further, in the inner surface side in the portion of taking one's seat 209 that the radiant heat of radial pattern heater 210 irradiates, in order to radiation-absorbing is warm better, radiant heat absorbent layer 217 is formed with.Further, this radiant heat absorbent layer 217 is also set to electrical insulating property.
Therefore, when breakage event occurs radial pattern heater 210, even if this filament 213 hangs down into side, the portion of taking one's seat 209 etc., also do not have the danger such as electric shock.
And then the outer peripheral face of described radial pattern heater 210 is clamped by the free end side arc sections of a pair holding piece 215a, 215b of leaf spring material, and, clamping plate 216 and its free end are fastened, prevents careless expanding thus.
Therefore, even if such as seat ring main body 203 is stood up or fell etc. when applying to impact, also the breakage accidentally coming off and cause thus of radial pattern heater 210 can be taken precautions against in possible trouble.
(embodiment 6)
Figure 30 represents embodiment 6, and basic structure is identical with embodiment 5, and difference is to improve the structure of thermostat.
That is, be with the difference of embodiment 5, in thermostat 220, radial pattern heater 210 side of bimetallic 222 is separated by hot permeation bodies 233 such as quartz glass.
Like this, hot permeation body 233 is utilized to separate, thus, be arranged to antidrip or water proof type that water droplet or dust can not invade thermostat 220 inside, just in case when intaking in blank part 208, also can enter the conducting parts of thermostat 220 by anti-sealing, can electric insulation be maintained, prevent from getting an electric shock.
When the thickness of slab of hot permeation body 233 is blocked up, hot through performance reduces, and therefore preferably thickness of slab is below 1.5mm, is more preferably below 1.2mm.
Further, in the respective embodiments described above, the material in portion of taking one's seat is the punch process product of aluminium sheet, and other processing methods such as cast aluminium also can obtain same effect.The kind of metal also can be copper coin or steel plate.

Further, be provided with infrared transmitting portion at the sidepiece 324 of main body 321, be built-in with the infrared ray sensor 325 detected with or without human body in lavatory within it.
In addition, main body 321 is provided with the LED341 as aviso device.
Figure 32 is the cross-section top view of the seat ring 322 in embodiments of the present invention 7, and Figure 33 is the main portion sectional view of the seat ring 322 in embodiments of the present invention 7.
Seat ring 322, engages fixing by the have metal upper frame body 326 of high thermal conductivity and the respective inner peripheral of lower frame body 327 and outer peripheral edge that are representative with aluminium etc., becomes the structure that inside has blank part 328 thus.
In the inside of this blank part 328, with the portion of taking one's seat of seat ring 322 relatively, be provided with the radiation reflective plate 329 that aluminium sheet carried out mirror process and the lamp heater 330 as radial pattern heater.In the end of this radiation reflective plate 329, along the all-round bending part be provided with upward, by this bending part, heat radiation from lamp heater 330 is partial to, therefore play the effect improved away from the edge, periphery of lamp heater 330 and the radiation density of Inner peripheral portions, realize the homogenising of the radiation profiles to upper frame body 326 radiation.
Near lamp heater 330, be provided with the thermostat 331 and temperature fuse 332 that are in series electrically connected with lamp heater 330, play for the unexpected dangerous state of affairs, prevent the effect that excessive temperature raises.
And, the inner surface of upper frame body 326 is provided with thermistor 333, and in main body 321, is provided with controller (not shown), this controller is according to the signal of this thermistor 333, control the energising to lamp heater 330, reach predetermined temperature to make the temperature in heating face.
And then lamp heater 330 is configured to, it is inner that tungsten filament 335 is applied in quartz ampoule 334, and inclosure is the gas 336 of main component by argon and nitrogen, plays the effect preventing tungsten filament 335 from consuming.
By adding halogen gas further in gas 336, along with tungsten filament 335 generates heat, repeatedly carrying out the halogen cycle reaction forming tungsten halide, the effect preventing tungsten filament 335 from consuming further can be played thus.
By this effect, using tungsten filament 335 little for thermal capacity as thermal source, the sharply rising of emittance can be carried out.
Figure 34 is the main portion sectional view of the upper frame body 326 of embodiment of the present invention 7, upper frame body 326, on upper frame body main body 337 inner surface utilizing the metal materials such as aluminium to be shaped, application contains the radiant heat absorbent layer 338 of a large amount of carbon black, and on the outer surface of upper frame body main body 337, application considers the surface decoration layer 339 of case hardness, chemical resistance, gloss etc.
Upper frame body main body 337, by being shaped by metal material with average thickness 1.2mm, while can improving thermal conductivity, due to its rigidity, plays the effect of the tectosome of seat ring.
Further, the thickness of the radiant heat absorbent layer 338 of application on inner surface is 0.1mm, can radiation-absorbing heat completely, simultaneously because thermal capacity is very little, can heat up instantaneously.
Further, the thickness of the surface decoration layer 339 of application on outer surface is 0.2mm, and the thermal capacity of this layer is also very little, therefore, it is possible to upper frame body main body 337 heated up instantaneously by the heat of conduction.
By said structure, when user enters lavatory, infrared ray sensor 325 detects this situation, and by this signal, lamp heater 330 is activated.The energy dropped into thus is converted to emittance instantaneously, is radiated to the direction of upper frame body 337 by quartz ampoule 334 and radiation reflective plate 329.
