(embodiment 1)
Fig. 1 is the cross section summary pie graph of major part of seat ring of the heating seat ring of embodiments of the present invention 1.Fig. 2 is the perspective view of toilet device that the closet of this heating seat ring is installed.Fig. 3 is a vertical view of pulling down the portion of taking one's seat of this heating seat ring.Fig. 4 is the decomposition diagram of this heating seat ring.Fig. 5 is the major part sectional view of the portion of taking one's seat of this heating seat ring.
In Fig. 1 to Fig. 5, the heating seat ring that has the warm water cleaning function of the anus that cleans behind the defecation or private parts, the main body 21 of growing crosswise is installed in the rearward end of the closet 20 of toilet device, the part of built-in warm water cleaning function in this main body 21, and can be provided with annular race 22 and the toilet cover 23 that is placed on the closet 20 with rotating freely.And, be built-in with the human body detection sensor 25 that has or not human body in the detection lavatory at the sidepiece of main body 21.Seat ring 22 constitutes as shown in Figure 1 by the top of plastic lower frame body 26, and the portion of taking one's seat 24 fixed engagement by encapsulant and aluminum form, and portion has the blank part 27 of the antidrip sealing of the intrusion that can stop water droplet etc. within it.
Inside at blank part 27, the portion of taking one's seat 24 of the seat ring 22 of taking one's seat with the user who uses toilet device relatively, be provided with radiant light reflecting plate 28 (reflector) that aluminium sheet is got through mirror finish and the both sides that are positioned at the portion of taking one's seat 24, as 2 lamp heaters 29 of a plurality of radial pattern heaters.Radiant light reflecting plate 28 as shown in Figure 1, full Zhou Shangyou of outer end is towards the kink 28a of top in it, by this kink 28a, the radiant light that lamp heater 29 sends is partial to, therefore play the effect of lifting, the homogenising of the thermal radiation distribution of the portion 24 that realizes taking one's seat away from the radiation density of the outer peripheral edges portion of the portion of taking one's seat 24 of lamp heater 29 and inner peripheral portion.Near this lamp heater 29, be provided with the thermostat 30 that in series is electrically connected with lamp heater 29, play the effect that dangerous state of affairs excessive temperature that the portion of taking one's seat 24 that prevents seat ring 22 takes place because of accident raises.In addition, radiant light reflecting plate 28 has adopted aluminium sheet for lightweight, also can use corrosion resistant plate or steel plating plate.
Lamp heater 29 constitutes the halogen of inactive gas 34 such as going into the filament 33 that formed by tungsten, argon at glass tube 32 inner sealings and trace, form the halogen cycle reaction of tungsten halide by the heating that repeats to be accompanied by filament 33, can play the effect that prevents that filament 33 from consuming.Can make that emittance rises rapidly with the very little filament 33 of thermal capacity as thermal source by this effect.That is, a kind of like this radial pattern heater of lamp heater 29, that is, for example the user enters the lavatory, takes off clothes, and buttocks is seated at before the portion of taking one's seat 24 of seat ring 22, in the moment in several seconds 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 a halogen lamp heater.
This lamp heater 29 is fixed on the radiant light reflecting plate 28 by the lamp heater fixture 36 that is formed by the leaf spring material, and radiant light reflecting plate 28 is fixed on the projection 37 of resinous lower frame body 26 by Screw.
Fig. 5 has represented to constitute the amplification cross section of a part of the portion of taking one's seat 24 of the aluminum of seat ring 22.In Fig. 5, blank part 27 1 sides of seat ring 22, promptly by the light-struck inner surface of the radiation of lamp heater 29, form and to absorb the radiation absorption layer 42 that being coated with of this radiant light dressed up black at an easy rate, the outside side of promptly taking one's seat is formed with the surface decoration layer 43 of the appearance of corrosion protection aluminium lamination 41 with anticorrosion ability and application hobby thereon.In addition, might not need to be provided with simultaneously the surface decoration layer 43 of corrosion protection aluminium lamination 41 and application, even certain one deck in the surface decoration layer 43 of corrosion protection aluminium lamination 41 or application also can have the anticorrosion ability of suitable chemical resistance etc. and the design of gloss and color etc.Yet,, just can access higher anticorrosion ability and for example contain the bacteria-eliminating efficacy that the coating of degerming material obtains by use if having the surface decoration layer 43 of corrosion protection aluminium lamination 41 and application simultaneously.In addition, about the color of radiation absorption layer 42, shades of colour is confirmed that the result who obtains is that black is that heat absorption efficiency is best, can accelerate the color of the programming rate of the portion of taking one's seat 24.In addition, be not limited to prestissimo, if the viewpoint can practical getting final product, even grey, redness, blueness etc. also could heat up.Even for black is not to only limit to application yet, also can use the surface treatment of dyeing etc.It also is practical using the alumite film to handle under the situation of aluminium.And, the surface decoration layer of implementing on the outer surface of the portion of taking one's seat 24 of Fig. 5 43 can use dyeing to handle, also can application, if but on the portion surface of taking one's seat, carry out application at least, not only obtain anticorrosion ability, even metal back-up thimbles such as aluminium also can be eliminated the sensation that seems cold, for example pass through the such pearly-lustre application of pearl etc., can deduce soft impression or senior impression.
Because the portion of taking one's seat 24 of seat ring 22 has used metal, particularly has been punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200WmK, compare the ground that differs greatly with about 0.1～1WmK of resin high, therefore at the radiant light of receiving light heater 29, when radiation absorption layer 42 heated up, the outer surface that can promptly heat be passed to the portion of taking one's seat 24 was a surface decoration layer 43.And, owing to be the high aluminium of thermal conductivity, therefore can access the equal more uniformly thermal effect of Temperature Distribution.And, by punching press (deep-draw) processing of aluminium, because work hardening, even the thickness of slab attenuation also can be guaranteed necessary strength.For example, under the situation of resin, from the angle of intensity, need the wall thickness about 3mm, if the punch process product of aluminium sheet, then the 1.5mm of a half thickness is following promptly enough.Because thin more, thermal capacity is more little, therefore can reduce heat up needed heat and time.From the angle of experimental result, intensity and heating-up time, the thickness of slab that obtains aluminium sheet is preferably the conclusion of 0.8～1.2mm.
And in the lower frame body 26 that constitutes seat ring 22, its inner face is equipped with radiant light reflecting plate 28, the thermostat 30 that lamp heater 29 is installed on this radiant light reflecting plate 28 and is connected in series with lamp heater 29.And the top of lower frame body 26 is equipped with the portion of taking one's seat 24 of aluminum, and the temperature for the portion of taking one's seat 24 of detecting this aluminum is equipped with the thermistor 44 as the seat ring temperature-detecting device on the inner surface of the portion of taking one's seat 24.And, seat ring 22 is formed with electrode 46 on its rotating shaft 45, constitute seat ring position detecting device 47 jointly with the bearing portion (not shown) of main body 21, be used to detect seat ring 22 and be the state of erecting, still the use location of approximate horizontal on closet 20 for taking one's seat and use.
In main body 21, be provided with control part 50 based on microcomputer, be taken into the temperature control of carrying out lamp heater 29 as the detection signal of the room temperature thermistor 48 of room temperature detector, and have timing portion 49, the elapsed time that the moment that the intensification that lamp heater 29 energisings from seat ring 22 are caused begins begins is carried out timing.And, control part 50 receives the human body detection sensor 25 that detects in people's inlet chamber, the signal of take one's seat checkout gear 38 and seat ring position detecting device 47, to the beginning of the energising of lamp heater 29 with stop to control, receive signal that thermistor 44, room temperature thermistor 48 send and lamp heater 29 is carried out temperature control make temperature as the portion of taking one's seat 24 of heating face reach predetermined temperature as preference temperature.
In Fig. 6, thermostat 30 is to expose in blank part 27 for the radiant light that makes bimetallic 51 receiving light heaters 29.And, be coated with the hear resistance blacking that is equipped with as radiant heat absorbing material 52 on the light receiving surface of bimetallic 51.And thermostat 30 constitutes by radiant heat absorbing material 52 and absorbs effectively from the heat of radial pattern heater to bimetallic 51 radiation, more promptly improves bimetallic temperature.And, thermostat 30 be set between the portion of taking one's seat 24 of lamp heater 29 and seat ring 22 apart from a greater than the distance b between lamp heater 29 and the bimetallic 51.This is the distance as the radiation absorption layer 42 of sensitive surface to the inner surface that is located at the portion of taking one's seat 24 in the present embodiment apart from a.
In the above-described embodiment, when the user entered the lavatory, human body detection sensor 25 detected it and enters, and this signal is sent to control part 50.At this moment, when confirming that by the signal of seat ring position detecting device 47 seat ring 22 is in the use location of approximate horizontal, control part 50 begins the energising to lamp heater 29.By this initial power-up, drop into energy moment to be transformed to emittance, emit to the portion of taking one's seat 24 directions of seat ring 22 through glass tubes 32 and radiant light reflecting plate 28 by filament 33.And then the emittance of lamp heater 29 makes the radiation absorption layer 42 and the portion 24 of taking one's seat of inner surface of the portion of taking one's seat 24 be located at seat ring 22 heat up.Like this, in the present embodiment, after the user enters the lavatory, can switch on to lamp heater 29, the heating face of the portion of taking one's seat 24 of transient heating seat ring 22 almost, even and for unexpected dangerous states of affairs that takes place such as the faults of control part 50, also can block the energising of lamp heater 29 by thermostat 30 by the quick response of the radiant light of bimetallic 51 receiving light heaters 29, therefore different with the such very big situation of insulation heat release loss of switching on all the time of the existing heating seat ring that is using prevailingly, realized almost there is not the heat release loss, extremely energy-conservation safety heating seat ring.In addition, the part of Fig. 3 and hinged cover 55 shown in Figure 4 under the situation of the heating seat ring (not shown) of the resin of existing general use for integrally formed with the portion of taking one's seat 24.In the above-described embodiment, Fig. 3 and the portion of taking one's seat 24 shown in Figure 4 are formed by metal (aluminium), and hinged cover 55 is shaped by acrylic resin.Its former because, be required Min. by the position that makes lamp heater 29 heating, need to reduce the thermal capacity of heating, thereby can with still less electric power more apace moment the portion of taking one's seat 24 is heated up, further save electric power.That is to say that heat conduction is carried out on the aluminium thermal conductivity highland of the portion 24 of taking one's seat, make temperature become effect equably, hinged cover 55 is a resin, because the low heat of therefore taking one's seat portion 24 of thermal conductivity can be absorbed by hinged cover 55 hardly.Like this, the parts of the upside by making seat ring 22 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 reduce the loss of heat.As mentioned above, constitute with lower frame body 26 by portion of taking one's seat 24 and hinged cover 55 as the upside component parts of seat ring 22, have inside have blank part 27 seat ring 22, be located in the blank part 27 radial pattern heater 29 and with these radial pattern heater 29 relative reflectors 28 that are located at lower frame body 26 sides, at least the portion of taking one's seat 24 of upper frame body is made of metal (aluminium), by the portion of taking one's seat 24 inner faces radiation absorption layer 42 is set, can realizes with the take one's seat energy-conservation transient heating seat ring of portion 24 of electric power transient heating more promptly still less at upper frame body.
In addition, the signal of thermistor 44, room temperature thermistor 48 when control part 50 begins according to energising, calculate by both temperature differences and temperature separately, the optimum value of the energising binding hours of the initial power-up that selection preestablishes, stores, reduce the energising amount when reaching the energising binding hours by elapsed time of timer 49 timing or be zero, the signal controlling energising amount based on thermistor 44 makes the portion of taking one's seat 24 of seat ring 22 be heated to preference temperature afterwards.
Thus, in fact thermistor 44 detects near the temperature the portion of taking one's seat 24 of user contact, control part 50 heats up accurately and maintains preference temperature, therefore can cosily use seat ring 22, and then based on the signal of thermistor 44 and room temperature thermistor 48, according to the input amount of load control emittance, therefore high accuracy and be heated to preference temperature safely more.
And,, after the energising binding hours, reduce the energising amount by preferentially carrying out the control of initial power-up time, slow down firing rate, even the response speed of seat ring temperature-detecting device postpones, also can heat seat ring safely, and can use cheap seat ring temperature-detecting device.Usually, general heater mostly is greatly by reduction and applies the Control of Voltage temperature, but lamp heater 29 carries out forming with the heating of filament 33 the halogen cycle reaction of tungsten halide by circulation, prevents the consumption of filament 33, when therefore the temperature of glass tube drops to 200 ℃, hinder the halogen cycle reaction.Therefore, make the portion of taking one's seat 24 rise to preference temperature, in the effective output area of halogen cycle, changed in the energising cycle and carry out in order to utilize lamp heater 29.
On the other hand, after seat ring 22 is in the state of erecting or male sex user and enters the lavatory, seat ring 22 is in when erecting state, based on the signal of seat ring position detecting device 47, control part 50 stops to 29 energisings of lamp heater.Can reduce the situation that heats seat ring 22 thus meaninglessly, further realize energy-conservationly, and can prevent under "on" position and on length direction, be subjected to the gravity effect and broken string etc. shorten the situation in life-span as the tension direction of filament 34.
And, according to user's purpose,, impact owing to relax as the lamp heater fixture 36 of the leaf spring material of elastomeric material even seat ring 22 was being opened and closed between the falling of state of erecting and approximate horizontal state, therefore can prevent glass tube or filament breakage.
Secondly, when the user takes one's seat for defecation,, the energising quantitative changeization is controlled, so that be zero or be the amount that the seat ring excessive temperature is raise to the energising amount of lamp heater 29 by 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, take one's seat, therefore need make sufficient consideration safety owing to the heating seat ring makes skin directly contact the seat ring that is built-in with the lamp heater.Under common user mode, safety and comfort ground uses as mentioned above, but owing to unexpected reason, microcomputer (not shown) control part 50 of etc.ing breaks down, and continues when lamp heater 29 is switched on etc., also needs to move safely.
Thermostat uses usually as shown in figure 10 and is wrapped in the metal lid 6 and the structure of blocking light in the bimetallic 7, in this structure, at first lid 6 is heated, bimetallic heating is by carrying out from the radiation of lid 6, therefore bimetallic reaches predetermined temperature needs spended time, therefore under the situation that the temperature of seat ring 22 changed in the short time, the cut-out of circuit produces delay sometimes.
Yet in the present embodiment, in order to address this problem, in the thermostat 30, bimetallic 51 exposes, on bimetallic 51 surfaces, as the stable on heating blacking of radiation-absorbing material 52 applications.Therefore, because the radiant light of bimetallic 51 direct receiving light heaters 29, therefore the radiant light from lamp heater 29 directly adds thermo bimetal 51, and on the surface of bimetallic 51 as the stable on heating blacking of radiation-absorbing material 52 applications, therefore the photothermal major part that arrives bimetallic 51 from lamp heater 29 is absorbed by bimetallic 51, can promptly follow the rapid change of the temperature of seat ring 22, because thermostat 30 in series is electrically connected with lamp heater 29, therefore when excessive temperature raises, can cut off the energising of lamp heater 29.
And then thermostat 30 is set in following position,, makes bigger than the distance between lamp heater 29 and the thermostat 30 apart from a between lamp heater 29 and seat ring 22 surfaces that is.Thus, the temperature that makes bimetallic 51 rises than the surface temperature of seat ring 22 and rises soon, therefore when unusual, and can be when also not reaching seat ring 22 surface temperatures and excessively raise, be in precarious position such as scald, cut off the power-on circuit of lamp heater 29, guarantee safety.
And, in the present embodiment,, then also can prevent the malfunction of thermostat 30 if the temperature of bimetallic 51 is raise fast.Promptly, if the temperature of bimetallic 51 is raise fast, then disconnection (power-on circuit of the lamp heater 29 opens circuit) operating temperature of thermostat 30 can be arranged to be higher than the common serviceability temperature of seat ring 22, therefore, thermostat 30 actions in the time of can avoiding using usually, the danger that the heating function of seat ring 22 can't use.
That is, Fig. 7 is illustrated in the thermostat 30 of structure shown in Figure 6, setpoint distance b=7mm, and apart from a=15mm, the result of near bimetallic 51 temperature and portion's 24 surface temperatures of taking one's seat when measurement is switched on to lamp heater 29.In Fig. 7, curve (A) is the surface temperature of the portion of taking one's seat 24, 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 51 of thermostat 30 is shown in curve (B), and is faster than the portion of taking one's seat 24, at t 2Time rises to seat ring control temperature (T 1).The portion 24 of taking one's seat reaches the highest design temperature (T of seat ring 22 2) when above, the temperature of bimetallic 51 reaches disconnection (opening circuit) operating temperature (T of thermostat 29 3), the power-on circuit of cut-out lamp heater 29.
And, just in case thermostat 30 breaks down, become under the situation of state of the power-on circuit that can't cut off lamp heater 29, reaching safety margin temperature (T 4) before, the action of the thermostat 31 (or temperature fuse) of non-restoring type, the power-on circuit of cut-out lamp heater 29.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 30 3) be set in the highest design temperature (T of seat ring 22 2) above and at safety margin temperature (T 4) below, thus, the power-on circuit of also easily having eliminated the lamp heater 29 that the thermostat 31 (or temperature fuse) of non-restoring type causes cuts off the danger that the heating function of seat ring 22 can't use.Promptly, the phase I of initial power-up time, the timer 49 of control part 50 and thermistor 44 carry out temperature control, second stage disconnects the power-on circuit (but because temperature reduces, circuit can restore) that cuts off lamp heater 29 by thermostat 30, phase III, cut off the power-on circuit (can't ReSet Circuit) of lamp heater 29 by the thermostat 31 (or temperature fuse) of non-restoring type, by the multilevel security function is set like this, safety and comfort ground uses for a long time.
And, in the present embodiment, as shown in Figure 3, the lamp heater 29b of the lamp heater 29 of front side and rear side is configured in the front and back of seat ring 22, and be provided with many, and being oppositely arranged thermostat 30,30b with each lamp heater 29,29b, each thermostat 30,30b in series are electrically connected.In addition, be set to restoring type thermostat 30,30b by operating temperature and disconnect action at a lower temperature, non-restoring type thermostat 31,31b disconnect action under the temperature higher than restoring type thermostat 30,30b, realize higher maltilevel security thus, and safety and comfort ground uses for a long time.
Promptly, be connected in series with thermostat 30,30b on each lamp heater 29, the 29b, and then they are connected in series, constitute the power-on circuit of lamp heater 29,29b, which no matter produce when unusual thus at lamp heater 29,29b, can both pass through the power-on circuit of thermostat 30,30b cut-out lamp heater 29,29b, therefore can 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 one of them thermostat 30 generation problem, when being in the state of the power-on circuit that can't cut off lamp heater 29,29b, also can utilize another thermostat 30b to cut off the power-on circuit of lamp heater 29,29b, thereby be safe.And, lamp heater 29,29b are separated into many, therefore, as shown in Figure 9 in existing annular race 2, be configured in by 1 lamp heater 4 ring-type seat ring 2 blank part 1 roughly on the whole, because the deflection of seat ring 2 and the step-up error of lamp heater 4 etc. and directly be applied with stress on lamp heater 4, and this problem is eliminated in the present embodiment, can eliminate the danger of lamp heater 29 breakages that the deflection etc. of seat ring 22 causes.

Fig. 8 is the partial cross section figure of major part sectional view, especially thermostat of the heating seat ring of embodiments of the present invention 2.The structure of the invention of present embodiment and embodiment 1 is basic identical, and difference is the structure of the thermostat that is connected in series with the lamp heater is improved, and therefore only the structure of different thermostats is described.
In Fig. 8, the lid of thermostat 30c 53 is formed by clear glass, so that bimetallic 51 receives the radiant light of lamp heater 29.In addition, by the lid 53 that clear glass is set, can be set as antidrip or water proof type that water droplet or dust can not invaded thermostat 30c inside, just in case during blank part 27 immersions, also can prevent the conducting parts intrusion of sealing, can keep electric insulation, prevent to get an electric shock to thermostat 30c.And, thermostat 30c and Fig. 6 similarly, the stable on heating blacking of application on the light receiving surface of bimetallic 51 is as radiant heat absorbing material 52.And thermostat 30 constitutes by radiant heat absorbing material 52 and absorbs effectively from the heat of radial pattern heater to bimetallic 51 radiation, improves bi-metal temperature more quickly.And thermostat 30c is configured to make bigger than the distance b between lamp heater 29 and the bimetallic 51 apart from a between lamp heater 29 and seat ring 22 surfaces.Therefore, because the radiant light of bimetallic 51 direct receiving light heaters 29, therefore the radiant light from lamp heater 29 directly adds thermo bimetal 51, and owing to scribble stable on heating blacking as radiant heat absorbing material 52 on bimetallic 51 surfaces, therefore the radiant heat major part that arrives bimetallic 51 from lamp heater 29 is absorbed by bimetallic 51, can promptly follow the rapid change of the temperature of seat ring 22, thermostat 30 in series is electrically connected with lamp heater 29, therefore when excessive temperature raises, can cut off the energising of lamp heater 29.
In addition, the clear glass of lid 53 uses quartz glass, so the radiant energy optical transmission characteristic good of lamp heater 29, responds faster, can improve the partition security.Certainly, also can use other glass as required.And when the thickness of slab of clear glass 53 was blocked up, transmission performance reduced, 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 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.

Figure 11 is the summary structure chart in major part cross section of the heating seat ring of embodiment of the present invention 3, Figure 12 is the perspective view that is equipped with the toilet device of this heating seat ring, Figure 13 pulls down the vertical view that the portion of taking one's seat of this heating seat ring represents, Figure 14 is the decomposition diagram of this heating seat ring, and Figure 15 is the major part sectional view of the portion of taking one's seat of this heating seat ring.
In Figure 11 to Figure 15, have the cleaning anus after an action of the bowels and the heating seat ring of the warm water cleaning function of private parts, the main body 121 of growing crosswise is installed in the rearward end of the closet 120 of toilet device, the part of built-in warm water cleaning function in this main body 121, and, can be provided with the ring-type seat ring 122 and the toilet cover 123 that are placed on the closet 120 with rotating freely.And, be built-in with the human body detection sensor 125 that has or not human body in the detection lavatory at the sidepiece of main body 121.As shown in figure 11, the portion of taking one's seat 124 that is formed by aluminium fixes and is combined in by encapsulant on the plastic lower frame body 126 and forms seat ring 122, and its inside has the blank part 127 that carries out the antidrip sealing that can prevent immersions such as water droplet.
In blank part 127 inside, the portion of taking one's seat 124 of the seat ring 122 of taking one's seat with the user who uses toilet device relatively, be provided with and aluminium sheet carried out the radiation reflecting plate 128 (reflector) of mirror process and as the headlight heater 129 of a plurality of radial pattern heaters that are in the portion of taking one's seat 124 both sides, back light heater 129b (after, be expressed as lamp heater 129 when there is no need to distinguish).Radiation reflecting plate 128 as shown in figure 11, the outer end has bending part 128a towards the top a full week in it, by this bending part 128a, radiant light from lamp heater 129 is partial to, therefore play the effect of raising, realize even to the thermal radiation distribution of the portion's of taking one's seat 124 radiation away from the radiation density of the outer peripheral edges portion of the portion of taking one's seat 124 of lamp heater 129 and inner peripheral portion.Near this lamp heater 129, be provided with the rdaiation response type thermostat 130 that in series is electrically connected with lamp heater 129, play for the unexpected dangerous state of affairs and prevent the effect that the excessive temperature of the portion of taking one's seat 124 of seat ring 122 raises.In addition, radiation reflecting plate 128 uses aluminium sheet in order to realize lightweight, but also can use corrosion resistant plate or steel plating plate etc.
Lamp heater 129 constitutes at inactive gas 134 and micro-halogen gas such as the filament 133 of glass tube 132 inner inclosure tungsten formations, argon gas, heating along with filament 133, form the halogen cycle reaction of tungsten halide repeatedly, can play the effect that prevents that filament 133 from consuming thus.By this effect, filament 133 that can thermal capacity is very little can carry out the rapid rising of emittance as thermal source.That is, lamp heater 129 is a kind of like this radial pattern heater,, can enter the lavatory from the user that is, takes off clothes, and buttocks is seated in the utmost point short time of for example several seconds till the portion of taking one's seat 124 the portion of taking one's seat 124 with seat ring 122 preference temperature that is rapidly heated.In addition, lamp heater 129 may not be a halogen lamp heater according to the situation of desired characteristic.
This lamp heater 129 is fixed on the radiation reflecting plate 128 by the lamp heater fixture 136 that is formed by the leaf spring material, and radiation reflecting plate 128 is fixed on the projection 137 of resinous lower frame body 126 by Screw.
Figure 15 is the take one's seat amplification sectional view of a part of portion 124 of the aluminum that constitutes seat ring 122.In Figure 15, blank part 127 1 sides of seat ring 122, be the light-struck inner surface of radiation of lamp heater 129, be formed with the radiation absorption layer 142 that is coated the black that can be easy to absorb its radiant light, the outside side of promptly taking one's seat forms and has the corrosion protection aluminium lamination 141 of anticorrosion ability and be the surface decoration layer 143 of the appearance application that obtains liking thereon.In addition, might not need to be provided with simultaneously the surface decoration layer 143 of corrosion protection aluminium lamination 141 and application, any in the surface decoration layer 143 of corrosion protection aluminium lamination 141 or application can have suitable anticorrosion ability and designs such as gloss and color such as chemical resistance.But this is two-layer for surface decoration layer by having corrosion protection aluminium lamination 141 and application 143, can have higher anticorrosion ability, and for example by using the coating that adds the degerming material, can also add bacteria-eliminating efficacy.And,, confirm that consequently, the heat absorption efficiency of black is the highest, can improve the programming rate of the portion of taking one's seat 124 for the color of radiation absorption layer 142 for shades of colour.In addition, if be not limited to maximum speed, from can practically getting final product this viewpoint, grey or redness, blueness etc. also can heat up.For black, be not limited to application, surface treatment such as also can dye.Under the situation of aluminium, alumite processing etc. are also practical.And, the surface decoration layer of implementing at the outer surface of the portion of taking one's seat 124 of Figure 15 143 processing of also can dyeing, if but implement application on the portion surface of taking one's seat at least, then not only obtain anticorrosion ability, even metal back-up thimbles such as aluminium also can be eliminated the sensation that seems cold, for example pass through the such pearly-lustre application of pearl etc., can deduce soft impression or senior impression.
The portion of taking one's seat 124 of seat ring 122 uses metal, particularly is punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200WmK, about 0.1～1WmK height than resin is very many, therefore radiant light that can receiving light heater 129, radiation absorption layer 142 heats up, and meanwhile to be communicated to the outer surface of the portion of taking one's seat 124 enough fast be surface decoration layer 143 to heat energy.And,, therefore can access the more uniform equal thermal effect of Temperature Distribution owing to be the higher aluminium of thermal conductivity.And work hardening even thickness of slab is thinner, also can be guaranteed necessary strength by punching press (deep-draw) processing of aluminium.For example, under the situation of resin, from the angle of intensity, need the wall thickness about 3mm, if the deep-draw processed goods of aluminium sheet, then the 1.5mm of a half thickness is following promptly enough.Because thin more, thermal capacity is more little, therefore heat up needed heat and time can reduce.From the angle of experimental result, intensity and heating-up time, the thickness of slab that obtains aluminium sheet is preferably the conclusion of 0.8～1.2mm.
And, constitute 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.And, the aluminum portion 124 of taking one's seat is installed on lower frame body 126 tops, in order to detect the take one's seat temperature of portion 124 of this aluminum, the thermistor 144 as the seat ring temperature-detecting device is installed on the inner surface of the portion of taking one's seat 124.And, seat ring 122 forms electrode 146 on its rotating shaft 145, constitute seat ring position detecting device 147 in the lump with the bearing portion (not shown) of main body 121, detect seat ring 122 and be positioned at the state of erecting, the use location of the approximate horizontal on closet 120 that perhaps being positioned to take one's seat uses.
On main body 121, be provided with control part 150 based on microcomputer, this control part 150 is taken into as the go forward side by side temperature control of portable lighter heater 129 of the detection signal of the room temperature thermistor 148 of room temperature detector, and have timing portion 149,149 pairs in this timing portion begins elapsed time from the moment that begins to heat up by lamp heater 129 energisings to seat ring 122 and carries out timing.And, control part 150 is taken into and detects the interior human body detection sensor 125 of people's inlet chamber or the signal of take one's seat checkout gear 138 and seat ring position detecting device 147, control is to the beginning of lamp heater 129 energising and stop, and be taken into signal from thermistor 144, room temperature thermistor 148, lamp heater 129 is carried out temperature control, so that reach predetermined temperature as preference temperature as the temperature of the portion of taking one's seat 124 of heating face.
In Figure 16, rdaiation response type thermostat 130 constitutes for the radiant light that makes bimetallic 151 receiving light heaters 129 and exposes in blank part 127, and lamp heater 129 is oppositely arranged with bimetallic 151.And, be coated with the hear resistance blacking that is equipped with as radiant heat absorbing material 152 on the light receiving surface of bimetallic 151.And rdaiation response type thermostat 130 constitutes by radiant heat absorbing material 152 and effectively absorbs from the heat of radial pattern heater to bimetallic 151 radiation, more promptly improves bimetallic temperature.And, rdaiation response type thermostat 130 be set between the portion of taking one's seat 124 that makes lamp heater 129 and seat ring 122 apart from a greater than the distance b between lamp heater 129 and the bimetallic 151.This is the distance as the radiation absorption layer 142 of sensitive surface to the inner surface that is located at the portion of taking one's seat 124 in the present embodiment apart from a.
In Figure 18, heat-conducting type thermostat 131 has lid 154 in the front of bimetallic 151 so that the bimetallic 151 direct radiant light of receiving light heater 129 not, and with the 129 relative settings of lamp heater.Lid 154 is formed by the thermal conductivity good metal, is to be formed by aluminium alloy at this, and its surface is provided with the radiant heat absorbing material that blacking forms.
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 the user entered the lavatory, human body detection sensor 125 detected it and enters, and this signal is sent to control part 150.At this moment, when confirming that by the signal of seat ring position detecting device 147 seat ring 122 is in the use location of approximate horizontal, control part 150 begins the energising to lamp heater 129.By this initial power-up, drop into energy moment to be transformed to emittance, emit to the portion of taking one's seat 124 directions of seat ring 122 through glass tubes 132 and radiant light reflecting plate 128 by filament 133.And then the emittance of lamp heater 129 makes the radiation absorption layer 142 and the portion 124 of taking one's seat of inner surface of the portion of taking one's seat 124 be located at seat ring 122 heat up.Like this, in the present embodiment, after the user enters the lavatory, can switch on to lamp heater 129, the heating face of the portion of taking one's seat 124 of transient heating seat ring 122 almost, even and the dangerous state of affairs that takes place for the accident that the fault of control part 150 etc. causes, by cutting off the energising of lamp heater 129 by the radiant light of bimetallic 151 receiving light heaters 129 and the rdaiation response type thermostat 130 of response fast, therefore with the insulation of switching on all the time of the existing heating seat ring that is using prevailingly, the situation difference that the heat release loss is very big, realized almost there is not the heat release loss, extremely energy-conservation and safe heating seat ring.In addition, the part of Figure 13 and hinged cover 156 shown in Figure 14 under the situation of the heating seat ring (not shown) of the existing resin that uses prevailingly for integrally formed with the portion of taking one's seat 124.In the above-described embodiment, Figure 13 and the portion of taking one's seat 124 shown in Figure 14 are formed by metal (aluminium), and hinged cover 156 is formed by acrylic resin.Its former because, be required Min. by the position that makes lamp heater 129 heating, need to reduce the thermal capacity of heating, thereby can further save electric power with still less the electric power transient heating portion 124 of taking one's seat more apace.That is, the aluminium thermal conductivity of the portion 124 of taking one's seat is carried out heat conduction than the highland, and temperature acts on equably, and hinged cover 156 is a resin, because the low heat of therefore taking one's seat portion 124 of thermal conductivity can be absorbed by hinged cover 156 hardly.Like this, the parts of the upside by making seat ring 122 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 reduce the loss of heat.As mentioned above, owing to be provided with: constitute with lower frame body 126 by portion of taking one's seat 124 and hinged cover 156 as the upside component parts of seat ring 122, and the seat ring 122 that has blank part 127 in inside, be located at the radial pattern heater 129 in the blank part 127, and with these radial pattern heater 129 relative reflectors 128 that are located at lower frame body 126 sides, and the portion of taking one's seat 124 of upper frame body is made of metal (aluminium) at least, the portion of taking one's seat 124 inner faces at upper frame body are provided with radiation absorption layer 142, thus can realize with still less electric power more promptly moment energy-conservation transient heating seat ring that the portion of taking one's seat 124 is heated up.
In addition, the signal of thermistor 144, room temperature thermistor 148 when control part 150 begins according to energising, calculate by both temperature differences and temperature separately, the optimum value of the energising binding hours of the initial power-up that selection preestablishes, stores, reduce the energising amount when reaching the energising binding hours by elapsed time of timer 149 timing or be zero, the signal controlling energising amount based on thermistor 144 makes the portion of taking one's seat 124 of seat ring 122 arrive preference temperatures afterwards.
Thus, in fact thermistor 144 detects near the temperature the portion of taking one's seat 124 of user contact, control part 150 heats up accurately and maintains preference temperature, therefore can cosily use seat ring 122, and then based on the signal of thermistor 144 and room temperature thermistor 148, according to the input amount of load control emittance, therefore high accuracy and be heated to preference temperature safely more.
And,, after the energising binding hours, reduce the energising amount by preferentially carrying out the control of initial power-up time, slow down firing rate, even the response speed of seat ring temperature-detecting device postpones, also can heat seat ring safely, and can use cheap seat ring temperature-detecting device.Usually, general heater mostly is greatly by reduction and applies the Control of Voltage temperature, but lamp heater 129 carries out forming with the heating of filament 133 the halogen cycle reaction of tungsten halide by circulation, prevents the consumption of filament 133, when therefore the temperature of glass tube drops to 200 ℃, hinder the halogen cycle reaction.Therefore, make the portion of taking one's seat 124 rise to preference temperature, in the effective output area of halogen cycle, changed in the energising cycle and carry out in order to utilize lamp heater 129.
On the other hand, after seat ring 122 is in the state of erecting or male sex user and enters the lavatory, seat ring 122 is in when erecting state, based on the signal of seat ring position detecting device 147, control part 150 stops to 129 energisings of lamp heater.Can reduce the situation that heats seat ring 122 thus meaninglessly, further realize energy-conservationly, and can prevent under "on" position and be subjected to the gravity effect and broken string etc. shorten the situation in life-span at length direction as the tension direction of filament 133.
And, purpose according to the user, even seat ring 122 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 136 of the leaf spring material of elastomeric material, therefore can prevent glass tube or filament breakage.
Secondly, when the user takes one's seat for defecation,, the energising quantitative changeization is controlled, so that be zero or be the amount that the seat ring excessive temperature is raise to the energising amount of lamp heater 129 by the signal of the checkout gear 138 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, take one's seat, therefore need make sufficient consideration safety owing to the heating seat ring makes skin directly contact the seat ring that is built-in with the lamp heater.Under common user mode, safety and comfort ground uses as mentioned above, but owing to unexpected reason, microcomputer (not shown) control part 150 of etc.ing breaks down, and continues when lamp heater 129 is switched on etc., also needs safety device to move reliably.Consider following situation as the situation that seat ring excessive temperature in using raises.Be that microcomputer control parts 150 such as (not shown) breaks down, continue when 129 energisings of lamp heater and thermistor 144 breaks down the situation when the seat ring temperature rises gradually.
Thermostat uses usually as shown in figure 10 and is wrapped in the metal lid 6 and the structure of blocking light in the bimetallic 7, in this structure, at first lid 6 is heated, bimetallic heating is undertaken by the radiation from lid, therefore bimetallic reaches predetermined temperature needs spended time, therefore at short notice under the situation of the variations in temperature of seat ring 122, the cut-out of circuit produces delay sometimes.In the present embodiment, in order addressing this problem, corresponding with many lamp heaters 129 rdaiation response type thermostat 130 and heat-conducting type thermostat 131 to be set, and they to be connected in series.
At first, rdaiation response type thermostat is described.Rdaiation response type thermostat 130 exposes bimetallic 151, as radiant heat absorbing material 152 stable on heating blacking of application on the surface of bimetallic 151.Therefore, because the radiant light of bimetallic 151 direct receiving light heaters 129, therefore the radiant light from lamp heater 129 directly adds thermo bimetal 151, and owing to be coated with the stable on heating blacking that is equipped with as radiant heat absorbing material 152 on the surface of bimetallic 151, therefore the radiant heat major part that arrives bimetallic 151 from lamp heater 129 is absorbed by bimetallic 151, can promptly follow the rapid variation of the temperature of seat ring 122, because rdaiation response type thermostat 130 in series is electrically connected with lamp heater 129, therefore when raising, excessive temperature can cut off the energising of lamp heater 129.
And then rdaiation response type thermostat 130 is set at, and makes bigger than the distance b between lamp heater 129 and the rdaiation response type thermostat 130 apart from a between lamp heater 129 and seat ring 122 surfaces.Thus, the temperature that makes bimetallic 151 rises than the surface temperature of seat ring 122 and rises soon, therefore when unusual, and can be when also not reaching seat ring 122 surface temperatures and excessively raise, be in precarious position such as scald, cut off the power-on circuit of lamp heater 129, thereby be safe.
And, in the present embodiment,, then also can prevent the malfunction of rdaiation response type thermostat 130 if the temperature of bimetallic 151 is raise fast.Promptly, if the temperature of bimetallic 151 is raise fast, then disconnection (power-on circuit of the lamp heater 129 disconnects) operating temperature of rdaiation response type thermostat 130 can be arranged to be higher than the common serviceability temperature of seat ring 122, therefore, rdaiation response type thermostat 130 work in the time of can avoiding using usually, the danger that the heating function of seat ring can't use.
That is, Figure 18 is illustrated in setpoint distance b=7mm in the thermostat 31 of structure shown in Figure 16, apart from a=15mm, measures when 129 energisings of lamp heater near the result of temperature and portion's 124 surface temperatures of the taking one's seat bimetallic 151.In Figure 18, curve (A) is the surface temperature of the portion of taking one's seat 124, 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 151 of rdaiation response type thermostat 130 is shown in curve (B), and is faster than the portion of taking one's seat 124, at t 2Time rises to seat ring control temperature (T 1).The portion 124 of taking one's seat reaches the highest design temperature (T of seat ring 122 2) when above, the temperature of bimetallic 151 reaches disconnection (opening circuit) operating temperature (T of rdaiation response type thermostat 130 3), the power-on circuit of cut-out lamp heater 129.
Therefore, break down at microcomputer etc., be under the state of the power-on circuit that can't cut off lamp heater 129, before reaching the safety margin temperature, the power-on circuit of lamp heater 129 is cut off in 130 actions of rdaiation response type thermostat.At this moment, the surface temperature of seat ring 122 does not reach safety margin temperature (T 4).And because rdaiation response type thermostat 130 be non-restoring type, so during 130 actions of rdaiation response type thermostat, later seat ring temperature just can excessively not raise.
Then, heat-conducting type thermostat 131 is described.Heat-conducting type thermostat 131 as shown in figure 17, and is identical with the structure of the existing thermostat of having represented in Figure 10 5, is wrapped in the lid 154 of metal in the bimetallic 151, cuts off the radiant light from lamp heater 129.In this structure, at first lid 154 is heated, and is undertaken by heat conduction and radiation from lid 154, therefore needs spended time till bimetallic reaches predetermined temperature.But the user sits on the seat ring 122, and when lamp heater 122 was in keeping warm mode with low output, heat-conducting type thermostat 131 was roughly the same temperature with the seat ring temperature.
Figure 19 represents that thermistor 144 breaks down, and can't accurately detect the temperature of seat ring 122, the temperature (curve D) of the bimetallic 151 of temperature of seat ring 122 (curve C) and heat-conducting type thermostat 131 when the seat ring temperature rises gradually.The seat ring temperature rises gradually, but the temperature of bimetallic 151 rises similarly, and the 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 (opening circuit) operating temperature (T of heat-conducting type thermostat 131 5) time, the power-on circuit of cut-out lamp heater 129.Therefore the temperature of bimetallic 151 and seat ring 122 reaches safety margin temperature (T at seat ring about equally 4) cut off the power-on circuit of lamp heater 129 before 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 that for example according to the environment for use difference seat ring does not have the situation of action when unusual.Therefore, heat-conducting type thermostat 131 is a restoring type, disconnects operating temperature (T at bimetallic 151 ratios 5) restore under the low temperature, can reuse.
And, rdaiation response type thermostat 130 is reached the highest design temperature (T of seat ring 122 in the seat ring surface temperature 2) above and at safety margin temperature (T 4) below disconnect action, but in fact, the disconnection operating temperature (T of rdaiation response type thermostat 130 3) can be set in safety margin temperature (T than seat ring 4) high temperature, therefore eliminated rdaiation response type thermostat 130 power-on circuit of turn-off lamp heater 129 easily, the danger that the heating function of seat ring 122 can't use.Promptly, the phase I of initial power-up time, the timing portion 149 of control part 150 and thermistor 144 carry out temperature control, second stage disconnects the power-on circuit (but because temperature reduces, circuit can restore) that cuts off lamp heater 129 by heat-conducting type thermostat 131, phase III, cut off the power-on circuit (can't ReSet Circuit) of lamp heater 129 by the rdaiation response type thermostat 130 of non-restoring type, by the multilevel security function is set like this, safety and comfort ground uses for a long time.
Promptly, as shown in figure 13, the lamp heater 129b of the lamp heater 129 of front side and rear side is 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, in series be electrically connected respectively.In addition, heat-conducting type thermostat 131, the 131b of restoring type disconnect action at a lower temperature, non-restoring type thermostat 130,130b disconnect action under than the high temperature of heat-conducting type thermostat 131, the 131b of restoring type, realize higher maltilevel security thus, and safety and comfort ground uses for a long time.
In addition, in the present embodiment, be oppositely arranged the thermostat of rdaiation response type and heat-conducting type with each lamp heater, under situation with a plurality of lamp heaters, on the optional position in a series of lamp heater, be oppositely arranged each thermostat, can carry out same safe action thus.And if having a plurality of thermostats of the same race, even in the thermostat then of the same race produces unusually, other thermostats can also carry out safe action effectively.
And, lamp heater 129,129b are divided into many, therefore, in the existing colyliform seat ring 2 shown in Figure 9, the blank part 1 that 1 lamp heater 4 of ring-type is configured in seat ring 2 roughly on the whole, thereby by the deflection of seat ring 2 and the step-up error of lamp heater 4 etc. directly on lamp heater 4 problem of stress application be eliminated, can eliminate the danger of lamp heater 129 breakages that the deflection etc. of seat ring 122 causes.
(embodiment 4)
Figure 20 is the partial cross section figure of the major part sectional view, particularly thermostat of the heating seat ring in the embodiments of the present invention 4.The structure of the invention of present embodiment and embodiment 3 is basic identical, and difference is the structure of the thermostat that is connected in series with the lamp heater is improved, and therefore only the structure of different thermostats is described.
In Figure 18, the lid of rdaiation response type thermostat 130c 153 is formed by clear glass, so that bimetallic 151 receives the radiant light of lamp heater 129.In addition, by the lid 153 that clear glass is set, water droplet or dust be can be set as and the antidrip or the water proof type of rdaiation response type thermostat 130c inside can not invaded, just in case when intaking in the blank part 127, also can prevent the conducting parts intrusion of sealing to rdaiation response type thermostat 130c, can keep electric insulation, prevent to get an electric shock.And, rdaiation response type thermostat 130c and Figure 16 similarly, the stable on heating blacking of application on the light receiving surface of bimetallic 151 is as radiant heat absorbing material 152.And rdaiation response type thermostat 130c absorbs from the heat of radial pattern heater to bimetallic 151 radiation effectively by radiant heat absorbing material 152, can improve bi-metal temperature more quickly.And, rdaiation response type thermostat 130c be configured between lamp heater 129 and seat ring 122 surfaces apart from a greater than the distance b between lamp heater 129 and the bimetallic 151.Therefore, because the radiant light of bimetallic 151 direct receiving light heaters 129, therefore the radiant light from lamp heater 129 directly adds thermo bimetal 151, and owing to scribble stable on heating blacking as radiant heat absorbing material 152 on bimetallic 151 surfaces, therefore the radiant heat major part that arrives bimetallic 151 from lamp heater 129 is absorbed by bimetallic 151, can follow the rapid change of the temperature of seat ring 122, rdaiation response type thermostat 130 in series is electrically connected with lamp heater 129, therefore when excessive temperature raises, can cut off the energising of lamp heater 129.
In addition, the clear glass of lid 153 uses quartz glass, so the radiant energy optical transmission characteristic good of lamp heater 129, respond quicker, the raising seperating safety.Certainly, also can use other glass as required.And when the thickness of slab of clear glass 153 was blocked up, transmission performance reduced, 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 of taking one's seat is the punch process product of aluminium sheet, but other processing methods such as cast aluminium also can access same effect.The kind of metal also can be copper coin or steel plate.
(embodiment 5)
In Figure 21 to Figure 25, can freely stand up by the main body 202 of growing crosswise and before it the fell seat ring main body 203 and the lid 204 of ground pivot setting of the seat ring that is installed in the present embodiment on the closet 20 of toilet device constitutes.
In described main body 202, be built-in with the part of warm water cleaning function, and in be provided with various control functions.And with these main body 202 one or human body detection sensor 205 independently is set, detecting the people, to enter the lavatory indoor, opens lid 204, perhaps makes the various control functions startings of main body 202.
But described seat ring main body 203 is by forming with the lower part: the leg 206 that one is set as the pivot of relative main body 202 is the two side-prominent synthetic resin system lower frame bodies 207 that form from the rear; By encapsulant and these lower frame body 207 watertights engage, constitute the portion of taking one's seat 209 that the Heat Conduction Materials such as aluminium of blank part 208 constitute in inside.
Be provided with in blank part 208: roughly radiation heaters 210 before and after 2 of configuration annularly, and the back that is positioned at these radial pattern heaters 210 promptly are positioned at the reflecting plate 211 of lower frame body 207 sides.
Front and back radial pattern heater 210 in series is electrically connected, the inactive gas such as argon gas that to sneak into micro-halogen are respectively enclosed the heat penetration that is made of sintered glass ceramics etc. and are crossed pipe 212 inside, wherein dispose filaments 213 such as tungsten, heating along with this filament 213, form the halogen cycle reaction of tungsten halide repeatedly, prevent the consumption of described filament 213 thus.
By described effect, filament 213 that can thermal capacity is very little carries out the rapid rising of emittance as thermal source.Be radial pattern heater 210, enter the lavatory the user, in time moment of for example several seconds till the portion of taking one's seat 208 of the seat ring main body 203 of taking one's seat, with this portion 208 of taking one's seat preference temperature that is rapidly heated.
In addition, radial pattern heater 210 may not necessarily use halogen according to the situation of desired characteristic.
If reflecting plate 211 is paid attention to lightweight then expected to use aluminium sheet, if not so, also can use corrosion resistant plate or steel plating plate etc.As shown in figure 21, the outer end has to the bending part 211a towards the top in full week within it, by this bending part 211a, is partial to from the radiant heat of radial pattern heater 210, effectively and equably heats the portion 209 of taking one's seat.
And described reflecting plate 211 is fixed on the lower frame body 207 on the formed projection 214 by Screw etc., and according to the height of this projection 214, between is set the gap of performance heat-blocking action.
Radial pattern heater 210 is kept by the anchor clamps 215 that methods such as welding are fixed on the leaf spring material system on the reflecting plate 211 by the lower end.More particularly, as shown in figure 25, described anchor clamps 215 are by the outer peripheral face of the free end side arc sections clamping radial pattern heater 210 of a pair of holding piece 215a, 215b, and fastening has clamping plate 216 on its free end, prevents that thus the careless expansion of described holding piece 215a, 215b from opening.
Clamping plate 216 are freely to dismantle, and when it was pulled down, nature can at random carry out installation, the dismounting of radial pattern heater 210 with respect to holding piece 215a, 215b.
As shown in figure 26, inner surface side in the portion of taking one's seat 209, be on the position of radiant heat irradiation of radial pattern heater 210, in order to absorb its radiant heat preferably, be formed with the radiant heat absorbed layer 217 of black and electrical insulating property, in the outside, the side of promptly taking one's seat is provided with the surface decoration layer 219 of lumariths 218 such as corrosion protection aluminium lamination and the application for the appearance of liking thereon.
In addition, may not need lumarith 218 and surface decoration layer 219 the two, any one is only arranged, can both have anticorrosion ability and designs such as gloss and color such as suitable chemical resistance.
But, by have lumarith 218 and surface decoration layer 219 the two, can access higher anticorrosion ability, and, also can add bacteria-eliminating efficacy for example by using the coating that adds the degerming material.
And for the color of radiant heat absorbed layer 217, the result that shades of colour has been carried out confirming is that the heat absorption efficiency of black is the highest, can improve the programming rate of the portion of taking one's seat 209.
If be not limited to maximum speed, from can practically getting final product this viewpoint, grey or redness, blueness etc. also can heat up.
When the described portion 209 of taking one's seat uses punching press (deep-draw) processed goods of aluminium, thermal conductivity is about 200WmK, about 0.1～1WmK height than resin is very many, therefore radiant heat that can receiver radiation type heater 210, radiant heat absorbed layer 217 heats up, and meanwhile heat energy is communicated to the surface decoration layer 219 of the portion of taking one's seat 209 enough fast.And,, therefore can access the more uniform equal thermal effect of Temperature Distribution owing to be the higher aluminium of thermal conductivity.And work hardening even thickness of slab is thinner, also can be guaranteed necessary strength by punching press (deep-draw) processing of aluminium.
For example, under the situation of resin, from the angle of intensity, need the wall thickness about 3mm, if the punch process product of aluminium sheet, then the 1.5mm of a half thickness is following promptly enough.Because thin more, thermal capacity is more little, therefore heat up needed heat and time can reduce.
From the angle of experimental result, intensity and heating-up time, the thickness of slab that obtains aluminium sheet is preferably the conclusion of 0.8～1.2mm.
Each radial pattern heater 210 both sides in front and back, in series be electrically connected each 2 thermostat 220 of configuration, and then, in the portion of taking one's seat 209, be equipped with each 1 accordingly with its sidepiece, amount to 2 temperature sensors 221 that thermistor is such, play, prevent the effect of the excessive temperature rising of the portion of taking one's seat 209 for the unexpected dangerous state of affairs.
At first, thermostat 220 adopts bimetallic 222 to be configured in the box 223 so that from the structure of the radiant heat direct irradiation of radial pattern heater 210 as shown in figure 27.Described bimetallic 222 is disk spring shape parts, is the border with the stop, selects a ground according to temperature and is inverted to 2 settling positions.
And, the stable on heating blacking of application on the radiant heat heating surface of this bimetallic 222, etc., form radiant heat absorbed layer 224, absorb radiant heat efficiently from radial pattern heater 210, can improve temperature more quickly.
And thermostat 220 is set to, and makes distance b between radial pattern heater 210 and the bimetallic 222 than radial pattern heater 210 and little apart from a between the portion 209 of taking one's seat.And this represents to be located at the distance till the radiation absorption layer 217 on the inner surface of the portion of taking one's seat 209 in the present embodiment apart from a.
In order between described radial pattern heater 210 and bimetallic 222, to guarantee the distance b of predetermined value, be provided with dividing plate shown in Figure 28 226 integratedly from the fixing body 225 that thermostat 220 is installed on the reflecting plate 211.That is, be formed on the circular-arc recess of front end of this dividing plate 226 and the circumference wall of radial pattern heater 210 and fasten the decision distance b.
On main body 202, be provided with control part 229 based on microcomputer, this control part 229 is taken into as the detection signal of 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 portion 228 subtend radiation heaters, 210 energisings.
And, control part 229 is taken into described human body detection sensor 205 or detects the signal that the user sits in the take one's seat checkout gear 230 and the seat ring position detecting device 231 of the portion of taking one's seat 209, control is to the beginning of radial pattern heater 210 energising and stop, and be taken into from detection take one's seat 2 temperature sensors 221 of temperature of portion 209 and the signal of described temperature sensor 227, radiativity heater 210 is carried out temperature control, so that reach predetermined value as preference temperature as the temperature of the portion of taking one's seat 209 of heating face.
And this control part 229 also carries out the control of lighting of display 232 such as indicator lamp, and taking one's seat to 210 energisings of radial pattern heater in beginning is in blink states when portion 209 does not reach predetermined temperature, be in continuous illuminating state when reaching predetermined temperature.
This display 232 is configured in lid 204 no matter and is in the position that any state of switching can both be confirmed, for example positions such as the place ahead upper surface of main body 202.
And then, as the take one's seat parts of temperature of portion 209 of detection, be provided with 2 temperature sensors 221, but control part 229 carries out the temperature control of radial pattern heater 210 when the temperature detection result of these temperature sensors 221 does not have deviation, when producing the deviation more than the preset range, stop to 210 energisings of radial pattern heater.
This is owing to opposite with the even heating purposes of the portion of taking one's seat 209, if predetermined above temperature deviation is arranged, can envision the problem on the safety.
In the above-described embodiment, when the user entered the lavatory, human body detection sensor 205 detected this situation, sent signal to control part 229.At this moment, by the signal of seat ring position detecting device 231, when confirming that seat ring main body 203 is positioned at the use location of approximate horizontal, the energising of control part 229 beginning radial pattern heaters 210.
By this initial power-up, drop into energy moment to convert radiant heat to, directly radiate and reflection back radiation on reflecting plate 211 to the direction of the portion of taking one's seat of seat ring main body 203.
The radiant heat that radiates to the direction of the described portion 209 of taking one's seat is absorbed efficiently by radiation absorption layer 217, and its result can be rapidly heated the portion of taking one's seat 209.
Like this, in the present embodiment, when the user enters the lavatory, to 210 energisings of radial pattern heater, the portion of taking one's seat 209 of transient heating seat ring main body 203 almost, even and during the unexpected dangerous state of affairs that causes for fault of control part 229 etc., because the radiant heat of the bimetallic 222 direct receiver radiation heaters 210 of thermostat 220, therefore can be fast to its response, cut off energising, therefore, with the insulation of switching on like that all the time of the existing general heating seat ring that uses, the bigger situation of heat release loss is compared, can realize almost not having the heat release loss, very energy-conservation and safe heating seat ring.
And, on seat ring main body 203, lower frame body 207 is formed by synthetic resin, and the leg 206 that portion is set as the relative pivot of main body 202 is one-body molded with this lower frame body 207, therefore the position that radial pattern heater 210 is heated is restricted to the required Min. of the portion of only taking one's seat 209, and suppress heat as much as possible and escape, therefore can utilize the small electric power portion 209 of will taking one's seat fast to heat up via leg 206.
And then, the temperature sensor 221 when control part 229 begins based on energising and the signal of temperature sensor 227, carry out computing according to temperature difference of the two or temperature separately, the optimum value of the energising binding hours of the initial power-up that selection preestablishes, stores, when switching on binding hours by the elapsed time arrival of timing portion 228 timing, reduce the energising amount or be zero, thereafter based on the signal controlling energising amount of thermistor 244, so that the portion 209 of taking one's seat becomes preference temperature.
Thus, near the portion of taking one's seat 209 of temperature sensor 221 detection user actual contact temperature, heat up well and maintain room temperature by control part 229 precision, therefore can cosily use seat ring, and, based on the signal of temperature sensor 221 and temperature sensor 227, 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, reduce the energising amount, reduce programming rate, even therefore the response speed of seat ring temperature-detecting device is slower, also can safely seat ring be heated, and can use cheap seat ring temperature-detecting device.
Usually, general heater applies voltage by reduction mostly and controls temperature, but the radial pattern heater 210 of halogen forms the halogen cycle reaction of tungsten halide repeatedly by the heating that is accompanied by filament 213, can prevent the consumption of filament 213 thus, therefore when the heat penetration temperature of crossing pipe 212 becomes below 200 ℃, hinder halogen cycle.Therefore, be made as preference temperature, in the effective output area of halogen cycle, changed in the energising cycle and carry out in order to utilize radial pattern heater 210 portion 209 of will taking one's seat.
On the other hand, after seat ring main body 203 is in the state of erecting or male sex user and enters the lavatory, seat ring main body 203 is in when erecting state, and based on the signal of seat ring position detecting device 231, control part 229 stops to 210 energisings of radial pattern heater.Can reduce the situation that heats seat ring main body 203 thus meaninglessly, further realize energy-conservationly, and can prevent under "on" position and be subjected to the gravity effect and the situation of reductions of service life such as broken string at length direction as the tension direction of filament 213.
And; according to user's purpose, even seat ring main body 203 was being opened and closed between the falling of state of erecting and approximate horizontal state, the anchor clamps 215 of leaf spring material system keep radial pattern heaters 210; therefore realization impact protection can prevent that heat penetration from crossing pipe 212 or filament 213 breakages.
Secondly, when the user takes one's seat for defecation,, the energising quantitative changeization is controlled, so that be zero or be the amount that the seat ring excessive temperature is raise to the energising amount of radiation heater 210 by the signal of the checkout gear 230 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 Direct Contact Heating seat ring 209, therefore need make sufficient consideration to safety.Under common user mode, safety and comfort ground uses as mentioned above, but owing to unexpected reason, microcomputer (not shown) control part 229 of etc.ing breaks down, and continues when radial pattern heater 210 is switched on etc., also needs to move safely.
Thermostat uses the structure that is wrapped in radiation-inhibiting heat in the metal lid in the bimetallic usually.In this structure, at first lid is heated, and bimetallic heating is undertaken by the radiation from lid, therefore needs spended time till bimetallic reaches predetermined temperature, therefore at short notice under the situation of the variations in temperature of seat ring, the cut-out of circuit produces delay sometimes.
And in the present embodiment, in order to address this problem, thermostat 220 directly is heated its bimetallic 222, and stable on heating blacking is arranged as radiant heat absorbed layer 224 at external coating.
Therefore, the photothermal major part that arrives bimetallic 222 from radial pattern heater 210 is absorbed by this bimetallic 222, can follow the rapid change of the temperature of 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, set the position of thermostat 220, in more detail, set distance b between its bimetallic 222 and the radial pattern heater 210 for than radial pattern heater 210 and short between the portion 209 of taking one's seat apart from a, thus, make the take one's seat surface temperature of portion 209 of the temperature-rise ratio of bimetallic 222 rise soon, carry out the safe action when unusual effectively.
Like this, if the temperature of bimetallic 222 is risen quickly, also can prevent the malfunction of thermostat 220.Promptly, if the temperature of bimetallic 222 is raise fast, then disconnection (power-on circuit disconnection) operating temperature of thermostat 220 can be arranged to be higher than the common serviceability temperature of seat ring, therefore, thermostat 220 actions in the time of can avoiding using usually, the danger that heating function can't use.
That is, Figure 29 is illustrated in setpoint distance b=7mm in the thermostat 220 of structure shown in Figure 27, apart from a=15mm, and near the result of temperature and portion's 209 surface temperatures of the taking one's seat bimetallic 222 during 210 energisings of measuring radiation type heater.
In Figure 28, curve (A) is the surface temperature of the portion of taking one's seat 209, and when room temperature was 5 ℃, 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 shown in curve (B), and is faster than the portion of taking one's seat 209, rises to seat ring control temperature (T1) in the t2 time.The portion 209 of taking one's seat reaches the highest design temperature (T2) of seat ring when above, 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 the radial pattern heater 210 is significant on safety, so its size management expectancy high accuracy.
Therefore, as shown in figure 28, be provided with dividing plate 226 integratedly, the circular-arc recess of the front end that is formed on this dividing plate 226 and the circumference wall of radial pattern heater 210 are fastened from the fixing body 225 that thermostat 220 is installed on the reflecting plate 211.Thus, the distance b between thermostat 220 and the radial pattern heater 210 is accurate, can carry out described safe action effectively.
In addition, in the present embodiment, make a part in a plurality of thermostats 220 of configuration (for example be configured in Figure 23 right side 2) be restoring type, all the other (for example are configured in Figure 23 left side 2) are non-restoring type, just in case restoring type thermostat 220 breaks down, become under the situation of state of the power-on circuit that can't cut off radial pattern heater 210, reaching safety margin temperature (T4) before, power-on circuit is cut off in thermostat 220 actions of non-restoring type.Consequently, the raceway surfaces temperature can not reach safety margin temperature (T4).
And, it is above and below safety margin temperature (T4) that the operating temperature (T3) of thermostat 220 is set in the highest design temperature (T2) of seat ring, thus, the thermostat 220 of having eliminated non-restoring type cuts off the power-on circuit of radial pattern heater 210, the problem that the heating function of seat ring can't use.
Promptly, the phase I of initial power-up time, the timer 228 of control part 229 and temperature sensor 221 carry out temperature control, second stage disconnects the power-on circuit (but because temperature reduces, circuit can restore) that cuts off radial pattern heater 210 by thermostat 220, phase III, thermostat 220 by non-restoring type cuts off power-on circuit (can't ReSet Circuit), and by the multilevel security function is set like this, safety and comfort ground uses for a long time.
In addition, by setting following operating temperature for, promptly, make restoring type thermostat 220 disconnect action in low slightly temperature, non-restoring type thermostat 220 disconnects action under the temperature higher than it, higher multilevel security performance can be set, and can use safely and cosily.
And a plurality of radial pattern heaters 210 constitute heating sources, therefore since the deflection of seat ring main body 203 and the step-up error of radial pattern heater 210 etc. and directly on this radial pattern heater 210 problem of stress application be eliminated, can eliminate damaged danger.Certainly, the configuration of radial pattern heater 210 itself also becomes simple.
And the inner surface side in the portion of taking one's seat 209 of the radiant heat of radial pattern heater 210 irradiation in order to absorb radiant heat better, is formed with radiant heat absorbed layer 217.And this radiant heat absorbed layer 217 also is set to electrical insulating property.
Therefore, when damaged accident takes place radial pattern heater 210,, do not have danger such as electric shock even this filament 213 hangs down into the portion's of taking one's seat 209 sides etc. yet.
And then the outer peripheral face of described radial pattern heater 210 is by the free end side arc sections clamping of a pair of holding piece 215a, the 215b of leaf spring material system, and, clamping plate 216 and its free end are fastened, prevent that thus careless expansion from opening.
Therefore, even for example seat ring main body 203 is stood up or fallen etc. and applies when impacting, also the breakage that comes off accidentally and cause thus of radial pattern heater 210 can be taken precautions against in possible trouble.
