Fig. 1 illustrates the major part section of seat portion of heating toilet seat of embodiments of the present invention and the figure that summary constitutes, and Fig. 2 is the stereogram that is equiped with the toilet apparatus of same heating toilet seat.Fig. 3 is for removing the plane that illustrates with the part of the seat portion of same heating toilet seat, Fig. 4 be same heating toilet seat the profile of seat portion.
In Fig. 2, have the heating toilet seat 11 of washing with the warm water cleaning function of after an action of the bowels the anus and the lower part of the body, in the rearward end of closet 20, be installed on the laterally long main part 21.The part of dress warm water cleaning function in main part 21.To be set to relative main part 21 free to rotate with covering 23 as the seat portion 22 that has in the colyliform week of the housing of mounting on closet 20.In other words, toilet apparatus, seat portion 22 mountings of heating toilet seat 11 on closet 20 and constitute.In addition, in the sidepiece of main part 21, be equipped with as the infrared ray sensor that detects the human detection unit that the toilet has or not human body (below be called detecting unit) 25.Human detection unit 25 also can be the CCD camera.Perhaps, as described later, also can otherwise constitute.
In 27 inside, cavity, be provided with the radiant energy reflecting plate that forms with seat portion 24 subtends (below be called reflecting plate) 28, on the reflecting plate 28 and seat portion 24 lamp formula heater (below be called heater) 29 is set with separating predetermined space.In other words, reflecting plate 28 relative heaters 29 are being arranged at the opposition side of seat portion 24.Reflecting plate 28, such as, be the aluminium sheet that mirror finish forms.Heater 29 is being arranged on a plurality of radial pattern heaters of the both sides of seat portion 24, irradiate near infrared rays.Because there is the space of appropriateness between seat portion 24 and heater 29, heater 29 and seat portion 24 can not contact and cause hot-spot and only utilize near infrared radiation to face toward a portion 24 and heat.In addition, by heater 29 is set in airtight cavity 27, human body can directly not contact with the heater 29 of high temperature and guarantee safety.Reflecting plate 28 as shown in Figure 1, has the bend 28A towards the top within it on the complete cycle of outer end.Bend 28A makes from the radiant energy of heater 29 deflection, improve from heater 29 leave the outer peripheral edges portion of seat portion 24 and the radiation density of inner peripheral portion.Therefore, make being evenly distributed of the radiant energy on directive housing 26 tops.Near heater 29, be provided with thermostat 30 and temperature fuse 31 as the working cell that is heated of connecting with heater 29 electricity, can prevent when unsafe situation takes place contingency that the excessive temperature of seat portion 24 from raising.The working cell that is heated, near the temperature heater 29 disconnect heater 29 by control during more than or equal to predetermined temperature.
Detecting unit 38, microswitch 40 set in the leg rubber 39 by the seat portion 22 of mounting on closet 20 constitutes.Detecting unit 38, the load by the user that takes one's seat in seat portion 24 makes microswitch 40 conductings detect the user and takes one's seat.Detecting unit 38 as described later, also can otherwise constitute.
In Fig. 4, the upper-part 26A of housing 26 has main body 41, is arranged on the top radiant energy absorbed layer (below be called absorbed layer) 42 of main body 41 and is arranged at more top superficial layer 43.Main body 41 is to use the transparent polypropylene resin material to be shaped in the injection molding forming mode.Absorbed layer 42 contains a large amount of carbon blacks.Superficial layer 43 is the whole visible lights from heater 29 emissions can be covered, and considers the light shield layer of case hardness, drug resistance, gloss etc.Superficial layer 43 is being arranged on the outer surface of seat portion 24, is made of the membrane material that covers absorbed layer 42.In addition, superficial layer 43 has the tone with the tonal match of the integral body of seat portion 22, is not limited to monochrome, also can have the polychrome combination and the pattern that designs etc.In addition, superficial layer 43 even will not cover from whole visible lights of heater 29 emissions, also can reach purpose of the present invention, and the part of this kind visible light is seen through.
In the recess 44C of the inner face opening of the upper-part 26A of housing 26, embed thermistor 44 as temperature detecting unit.Thermistor 44, detect by heater 29 heating near the temperature of absorbed layer 42 of seat portion 24.
In addition, form electrode 46 on the turning cylinder 45 of present portion 22, constitute position detection unit (below be called detecting unit) 47 in the lump with the bearing portion (not shown) of main part 21.Detecting unit 47 detects the use location that seat portion 22 is in the state of erecting or is being in the operable substantial level on closet 20 of seat.
Below thermostat 30 is elaborated.Fig. 5 illustrates the section of thermostat 30.Thermostat 30 has bimetallic 51 as being subjected to hot cell.Bimetallic 51 exposes with heater 29 subtends, is coated with stable on heating blacking in its surface as radiant energy absorbing material (below be called absorbing material) 52.So thermostat 30 utilizes absorbing material 52 can absorb expeditiously from the energy of heater 29 to bimetallic 51 radiation.Therefore, the temperature of bimetallic 51 rises rapidly.In addition, for thermostat 30, preferably with heater 29 and the distance 57 between the surface of seat portion 24 be set at greater than the distance 56 between heater 29 and the thermostat 30.
In addition, heater 29 preferably is configured as its actual range 57 on surface with seat portion 24 necessarily on its longitudinal direction, and the distance 61 of itself and reflecting plate 28 also is configured as necessarily.As a result, the distance that radiant energy arrives the surface of seat portion 24 becomes necessarily, and the temperature of seat portion 24 surfaces is even, can improve comfortableness.
Work to heating toilet seat 11 with above-mentioned formation is illustrated below.When the user entered into the toilet, detecting unit 25 detected it and enters, and this signal is sent to control module 50.At this moment, the signal that utilizes detecting unit 47 to send, when confirming that seat portion 22 is in the use location of the level of being actually, 50 pairs of heaters 29 of control module begin energising.By this initial power-up, drop into the instantaneous radiant energy that is transformed to of energy, launch to the direction of main body 41 through glass tube 32, reflecting plate 28 from filament 33.In addition, the radiant energy of heater 29, at the absorbed inside or the antireflection part of main body 41, but it most sees through and absorbed layer 42 and superficial layer 43 is heated up.Like this, heater 29 is switched on when the user enters the toilet, almost instantaneous being heated of heating surface of seat portion 24.Therefore, heating toilet seat 11 needn't keep energising always, is beneficial to very much energy-conservation.
Like this, thermistor 44, detect the contact of user in fact near the temperature of seat portion 24, control module 50 reaches its intensification with high accuracy and keeps suitable temperature.Therefore, the use of seat portion 22 is very comfortable, and because control module 50, based on the signal of thermistor 44,48, correspondingly the input amount of radiant energy is controlled with load capacity, is heated to suitable temperature so can incite somebody to action seat portion 24 safely with high accuracy more.
In addition, control module 50 preferentially carries out the control of initial power-up time, and the energising amount that reduces heater 29 after the energising binding hours reduces programming rate.Therefore, even the response speed of temperature detecting unit (thermistor 44) is slow, also can heat safely facing to seat portion 24.In addition, thermistor 44 also can use cheap product.Usually, mostly general heater is that reducing to apply voltage controls temperature.Relative therewith, heater 29 is followed the heating of filament 33, and the halogen cycle reaction of tungsten halide takes place to form repeatedly, can prevent the consumption of filament 33.Therefore, during smaller or equal to 200 ℃, the halogenation circulation becomes unstable in the temperature of glass tube.So, make seat portion 24 become suitable temperature in order to utilize heater 29, power cycles is carried out with changing.
On the other hand, when seat portion 22 is in the state of erecting, male sex user enters into after the toilet, and a portion 22 is become when erecting state, and control module 50 stops energising to heater 29 according to the signal of detecting unit 47.
In addition, fixture 36 has the rubber bushing 35 as elastomeric material, and the reflecting plate 28 of mounting having heaters 29 has rubber feet 37.Therefore, even the user erects the switching of state and level according to purpose to seat portion 22, because these impact-attenuating effects can absorb the impact to heater 29.Thereby can prevent the breakage of glass tube 32 and filament 33.
When the user took one's seat for defecation, control module 50 utilized the signal of detecting unit 38, and can to make energising amount to heater 29 be zero or be the energising amount of the temperature that makes a portion 22 till can excessively not rising by control.As a result, in use the temperature of seat portion 22 can not rise excessively, and the user needn't worry can be waited by scald and can use safely,
Owing to the user is that the seat portion 22 that the direct contact of skin is built-in with heater 29 takes one's seat, so must take into full account safety problem especially for heating toilet seat 11.Under common user mode, heating toilet seat 11 as mentioned above, can use safely and cosily.Yet, just in case constituting occasion of breaking down in the microcomputer etc. of control module 50 and the energising of heater 29 being proceeded or the like for a certain reason and also must work safely.Therefore, heating toilet seat 11 has the thermostat 30 of connecting with heater 29.Because the bimetallic 51 of thermostat 30 exposes, directly heat by radiant energy from heater 29.In addition, preferably absorbing material 52 is set on bimetallic 51 surfaces.So, the radiant energy that arrives bimetallic 51 from heater 29 is almost all absorbed by bimetallic 51.Therefore, thermostat 30 also can be rapidly correspondingly changes the power-on circuit of cut-out heater 29 when excessive temperature raises with the rapid change of the temperature of seat portion 22.In addition, be more preferably and also apply stable on heating blacking as absorbing material 52.Blacking can absorb the temperature that makes bimetallic 51 from the heat of heater 29 effectively and rise.
In addition, for thermostat 30, preferably be with its set positions make heater 29 and seat portion 22 the distance 57 between the surface of seat portion 24 greater than the distance 56 between heater 29 and the thermostat 30.As a result, the rising of the temperature of bimetallic 51 is faster than the rising of the surface temperature of seat portion 24.Therefore, taking place when unusual, when excessively rising becomes the precarious position that causes scald etc., can cut off the power-on circuit of heater 29 in the surface temperature of seat portion 24.
In addition, in the time can making the temperature fast rising of bimetallic 51, also can prevent delaying work of thermostat 30.In other words, in the time can making the temperature fast rising of bimetallic 51, disconnection (power-on circuit of the conducting heater 29) operating temperature of thermostat 30 can be set at the common serviceability temperature that is higher than a portion 22.Therefore, when using usually, just can avoid thermostat 30 work and make the out of use situation of heating function that heats toilet seat 11.
Utilize Fig. 6 to be explained below.Fig. 6 is the temperature controlled performance plot of heating toilet seat 11.In addition, in the thermostat 30 of formation shown in Figure 5, apart from 56=7mm, apart from 57=15mm.Fig. 6 be illustrated in near the temperature bimetallic 51 of the occasion of heater 29 energising and seat portion 24 surface temperature over time.Curve 58 is representing that the surface temperature of seat portion 24 changes, and can heat up in the time (about 7.5 seconds) of t1 when room temperature is 5 ℃ reaches common control temperature (Ta).On the other hand, the temperature of the bimetallic 51 of thermostat 30 shown in curve 59, can rise to temperature T a in the time of t2 soon than seat portion 24.When seat portion 24 became the highest design temperature (Tb) of a portion 22, the temperature of bimetallic 51 arrived the disconnection operating temperature (Tc) of heater 29, and thermostat 30 cuts off the power-on circuit of heater 29.
In addition,, arrive safety clearance temperature (Td) before, temperature fuse 31 work and cut off the power-on circuit of heater 29 in the occasion of the state that becomes the power-on circuit that can not cut off heater 29 just in case thermostat 30 breaks down.At this moment, the surface temperature of seat portion 22 does not reach temperature T d.
In addition, the work temperature c of thermostat 30 is set at more than or equal to the highest design temperature Tb of seat portion 22 and smaller or equal to safety clearance temperature T d.As a result, can not be easy to occur the power-on circuit of the heater 29 that causes by temperature fuse 31 disconnection, can not use the situation of the heating function of a portion 22.
As mentioned above, in the phase I of the security function of initial power-up time, control module 50 utilizes timer 49, thermistor 44 controlling the temperature of seat portion 24.In second stage, utilize the disconnection of thermostat 30 to cut off the power-on circuit of heater 29.In this occasion, because temperature descends, circuit may reduce.In the phase III, temperature fuse 31 fuses and the power-on circuit of cut-out heater 29.In this occasion, circuit can not restore.Like this, by setting triphasic security function, heating toilet seat 11 can use for a long time, safely and cosily.
In addition, in the present embodiment, as shown in Figure 3, it is a plurality of that heater 29 is that the both sides of present portion 22 are provided with, and with each heater 29 subtends thermostat 30 is set.Each thermostat 30 is electricity series connection.In addition, preferably the different thermostat 30 of disconnection operating temperature is set with each heater 29 subtends.In addition, in Fig. 3, not shown connection form.
In other words, preferably each heater 29 is connected with thermostat 30, these thermostat 30 series connection is constituted the power-on circuit of heater 29 again.In this constitutes, unusual occasion takes place at any one heater 29, thermostat 30 all will cut off the power-on circuit of heater 29.In addition, even, become the occasion of the state of the power-on circuit that can not cut off heater 29, also can cut off the power-on circuit of heater 29 by another thermostat 30 just in case in a thermostat 30, break down.Therefore, the energising to two heaters 29 can make it to stop safely.In addition, each heater 29 is being provided with when disconnecting the mutually different thermostat 30 of operating temperature,, is also having another thermostat 30 work even in disconnecting the low thermostat 30 of operating temperature, take place unusually.
In addition, heater 29 can be divided into a plurality of.Therefore, with the present portion 22 of a lamp formula heater configuration of colyliform almost whole empty 27 in occasion compare, can eliminate the stress that puts on lamp formula heater.This stress is owing to the bending of seat portion 22 and the step-up error of lamp formula heater etc. produce.Therefore, can eliminate because the danger of the breakage of the heater 29 that the bending of seat portion 22 etc. cause.
Another preferred implementation to thermostat is illustrated below.Fig. 7 A～Fig. 7 C is the diagrammatic sketch of work of thermostat 60 of the heating toilet seat of embodiments of the present invention.
Thermostat 60 has the 1st bimetallic (below be called bimetallic) 53 and 2nd bimetallic different with the disconnection operating temperature of bimetallic 53 (below be called bimetallic) 54 in inside.Bimetallic 53,54, the same with bimetallic 51, expose to heater 29.In addition, absorbed layer 52 preferably is set.
In the occasion of thermostat 30 operate as normal, shown in Fig. 7 A, reach the occasion that disconnects operating temperature at the bimetallic 53 that directly receives the radiant energy of heater 29, overturn.So the contact 55 of connecting with the power-on circuit of heater 29 becomes disconnection and the power-on circuit of cut-out heater 29.
In addition, shown in Fig. 7 B, just in case make bimetallic 53 that the occasion of bending takes place for a certain reason, the situation that bimetallic 53 can not break 55 can appear.In this kind occasion, shown in Fig. 7 C, also be under than the high temperature of the disconnection operating temperature of bimetallic 53, bimetallic 54 directly receives the radiant energy of the heater 29 that excessive temperature have risen and overturns.Bimetallic 54, the break 55 and power-on circuit of heater 29 is cut off safely.In this occasion, because bimetallic 54 is work when contact is unusual, be non-restoring type therefore, afterwards, preferably heater 29 no powers are guaranteed safety.
In the above description, what illustrate is to use thermostat 30 as being heated the example of working cell, but is not limited thereto.Such as, shown in Figure 35 A, 35B, can use the switch 141 that utilizes shape memory alloy spring (below be called spring) as being subjected to hot cell.Figure 35 A illustrates the state just often of the switch 141 that utilizes shape memory alloy spring 143, and Figure 35 B illustrates the state when unusual.In Figure 35 A, switch 141 has loading spring (below be called spring) 142 and spring 143.Spring 142, such as, generally use stainless steel, and spring 143, such as, the Ti-Ni alloy generally used.Spring 143 is compared with spring 142 at low temperatures, and coefficient of elasticity is little, and spring 143 is in compressive state, at this moment contact 144 closures.In other words, do not using heating during toilet seat, carrying out keeping this state in the temperature range of normal heating with heater 29.On the other hand, when making near the temperature of heater 29 become high temperature owing to a certain reason heater 29 abnormal heatings, shown in Figure 35 B, it is big that the coefficient of elasticity of spring 143 becomes, and spring 142 becomes compressive state.This moment, contact 144 disconnected, and the energising of heater 29 is stopped.Like this, also can obtain the effect same by the switch that utilizes shape memory alloy spring with thermostat.Spring 143 preferably also is the radiant energy absorbing material that coating comprises stable on heating blacking.
Below, be that the center is narrated the manufacture method of heating toilet seat 11 with seat portion 22.Seat portion 24, is to have printed the superficial layer 43 of absorbed layer 42 in advance, is installed in the metal pattern that the upper-part 26A of seat portion 22 is shaped, and utilizes injection molding forming to make the transparent polypropylene resin material forming that forms main body 41.Or at the superficial layer 43 that will print absorbed layer 42 in advance, utilize after the shape of preliminary forming for upper-part 26A such as vacuum forming, be installed in the metal pattern that upper-part 26A is shaped and carry out injection molding forming.

, the bearing portions of main part 21 and the turning cylinder 45 of seat portion 22 made up, make main part 21 and seat portion 22 be mounted for and to rotate thereafter.In this state, each electric parts that are included in main part 21 and the seat portion 22 are connected up.So just be assembled into heating toilet seat 11.
In addition, in the above description, be so that the optimal heat of heating surface is distributed as uniform heat distribution is that prerequisite describes.Herein, not uniform occasion in optimum heat distribution, by changing the figure (printing shape) of absorbed layer 42, can be easy to heat distribution is operated, can realize multiple distribution.Such as, also can be formed on the distribution that with the temperature sense interlock of human body Temperature Distribution is provided with gradient on the surface of seat portion 24.Also can as optimum heat distribution, realize comfortable heating in this occasion by the printing operation of absorbed layer 42.
Fig. 8 be the performance plot of radiant energy of seat portion 24, Fig. 9 A, Fig. 9 B are the diagrammatic sketch that the configuration example of absorbed layer 42 is shown.Wherein, absorbed layer 42 has distribution aspect the uptake of radiant energy in the surface of seat portion 24 vis-a-vis.The surface of seat portion 24, with the distance of heater 29 be one regularly, the radiant energy that arrives seat portion 24 surfaces is even, the surface temperature of seat portion 24 also is necessarily.Yet, in fact, seat portion 24 and be subjected to restriction in seat cushion fabric and the design, it must be difficult keeping with the distance of heater 29, as shown in Figure 8, produces aspect the intensity of radiant energy and distributes 64.In other words, near the radiant energy grow of the part of heater 29, the temperature of this part raises.On the other hand, with the part of the distance of heater 29 in, radiant energy dies down, the temperature of this part reduces.So to absorbed layer 42, it is preferred making from heater 29 emission, the radiant energy intensity distributions of outer surface that arrives seat portion 24 and the uptake distribution 65 opposite in fact formations of radiant energy.In other words, shown in Fig. 9 A, to use near the part of heater 29 reflected radiation can white, silver-colored class pigment 66, and make its black pigment that is gradually varied to absorbed radiation energy 67.Perhaps, shown in Fig. 9 B, also can print white, silver-colored class pigment 66 and black pigment 67 alternately, make at interval corresponding to radiant energy intensity to change.X-X wherein illustrates and heater 29 corresponding positions.Like this, by making lip-deep radiant energy intensity homogenising, can alleviate the inhomogeneous of seat portion 24 lip-deep temperature and obtaining comfortable seat portion 22 in seat portion 24.
Figure 10 is the profile that another formation of seat portion 24 is being shown.In seat portion 24, on the main body 41 of using transparent polypropylene resin to constitute, form the absorbed layer 42 that constitutes by printed film by injection molding forming.And then, on absorbed layer 42, form the dyed layer 43A that constitutes by printed film, and form the superficial layer 43B that the membrane material by light transmission constitutes on the outer surface.In other words, dyed layer 43A is arranged between the superficial layer 43B and absorbed layer 42 as membrane material.
In order to form this seat portion 24, print dyed layer 43A in advance, the superficial layer 43B that will print absorbed layer 42 more thereon is encased in the metal pattern of upper-part 26A, is shaped with method same as described above.Dyed layer 43A covers from heater 29 visible light emitted, and has and color matching that seat portion 22 integral colors are coordinated, is not limited to monochrome, also can use the combination of polychrome and style of designization or the like.In addition, also can make wittingly and see through from the part of heater 29 visible light emitted.Superficial layer 43B is transparent substantially, can protect dyed layer 43A and acquisition to have the surface state clearly of transparent feel.Like this, when the transparency of the material of superficial layer 43B is high, can makes the color of dyed layer 43A obtain respond well reflection from the teeth outwards, but, also can use opaque material of part or painted a little hyaline membrane in order to make it have pattern effect.
Below preferable shape, the configuration of lamp formula heater and preferred other heaters that are provided with except that lamp formula heater are described.
Figure 11 is the plane that removes a part of another heating toilet seat of embodiment of the present invention.The dissimilarity of the formation of Figure 11 and the formation of Fig. 3 be heater 29 shape, dispose and be provided with flexible cord heater (below be called heater) 62 this some.In addition formation is identical with the formation of Fig. 3.
In other words, in 27 inside, cavity, the seat portion 22 of taking one's seat with the user who uses toilet apparatus seat portion 24 subtends, be provided with the reflecting plate 28 that the aluminium sheet by mirror finish constitutes.And, two heaters 29 are set as the radial pattern heater in the both sides of seat portion 24.
Reflecting plate 28 and heater 29 are according to the shape setting of seat portion 22.In other words, as shown in figure 11, heater 29, be viewed as in the plane colyliform among the transverse part 24A of seat portion 24 the shape ground along seat portion 22 be provided with.Transverse part 24A is the position that huckle contacted when the people takes one's seat.
With the corresponding part of rear portion 24B of heater 62 heating in thermistor 44A is set.So, control module 50, the signal of acquisitor's health check-up measurement unit 25, detecting unit 38 and position detection unit 47, control is to the beginning of the energising of heater 29 and stop.In addition, obtain, the temperature of heater 29,62 controlled from thermistor 44,44A, 48 signal so that as heating surface the temperature of seat portion 24 become predetermined temperature as suitable temperature.Utilize such formation, can carry out the temperature control of very fine that the temperature of each heater is controlled respectively, and, stop or the like because also can detect the heating that abnormal temperature rises, broken string causes, so control module 50 can carry out suitable corresponding with various situations.
As mentioned above, heater 29 because be to switch on when the user enters the toilet, can be heated by almost instantaneous heating surface facing to seat portion 24, so do not need to keep energising always, is very energy-saving radial pattern heater.By the transverse part 24A of heater 29 heating, such as, can when 15 ℃ of room temperatures, be warmed up to the temperature (27～28 ℃) of the degree of not feeling cold in about 4 seconds.In other words, when detecting unit 25 detects the someone and enters into the toilet, can between to seat portion 24, taking one's seat, heat facing to seat portion 24.Like this, heater 29 can be instantaneous to heat contacting transverse part 24A seat portion 24, the contacted position of thermally sensitive huckle at first, the user can very cosily use a portion 22.
On the other hand, in the 24B of the rear portion of seat portion 24, when detecting unit 25 detects the someone and enters into the toilet, just increase energising amount, heat up to predetermined heating-up temperature to heater 62.In this occasion,, therefore can not as the intensification that utilizes heater 29, temperature sharply be risen because the heat that sends from heater 62 is delivered to the surface from seat portion 24 back sides by heat.Yet rear portion 24B is and the contacted position of thermally sensitive buttocks unlike huckle, even its temperature of never feeling cold degree is heated up lentamente, also can not damage the warming sense of whole seat portion 22.Like this, correspondingly use heater 29 and heater 62, can obtain comfortable warming sense by contact site with human body.Like this, to heat be preferred to heater 29,62 facing to seat portion 24 with different sequential respectively.
In addition, be to carry out to the explanation of heater 29, but be not limited thereto with the formation that pair of right and left is set.Also can increase the number of heater 29 as required, it is further disposed corresponding to the shape ground of seat portion 22.Also can realize meticulousr heating in this case to the control of switching on of each heater 29.In addition, describe with heater 62 as the heat-conduction-type heater, but be not limited thereto, also can use heater that metal patternization is formed with flat shape, have heater of ptc characteristics or the like.
In addition, heater 29, the center line A-A that preferably is disposed at than seat portion 24 locates in the inner part, keeps roughly equidistant 63 ground to form curved shape with the interior all of seat portion 24.When taking one's seat in the present portion 22 of people, load necessarily puts on the inboard, and contact-making surface also concentrates on the inboard, and contact pressure also is inboard high.Therefore, by serving as the main radiation heating of realizing with this part, can obtain more comfortable heating.In other words, because by with the central shaft arrangement of heater 29 in than seat portion 22 the center line A-A of seat portion 24 locate in the inner part, the toilet seat inboard that feels cold is easily heated, thus can be when toilet seat be taken one's seat imperceptible cold and cosily use the heating toilet seat.
Below to relating to the detailed formation of control module 50, the formation of conducting/disconnection of being used for heater 29 is switched on is described.
Figure 12 is the diagrammatic sketch of configuration example that the control system of heating toilet seat shown in Figure 1 is shown.Seat portion 22 has the cavity in inside, places heater 29 and as the thermistor 44 of temperature detecting unit.In main part 21, place as detecting unit seat sensor (below be called sensor) 38A, heater 29 control usefulness triode ac switch device 72 and detect industrial voltage AC100V AC signal zero point zero hand over testing circuit (below be called circuit) 73.In addition, also place heater control module (below be called control module) 74, buffer 75, the resistance 76 of connecting and the receiving element 25B that will receive or the like from the signal that sends as the human body detection sensor of human detection unit (below be called sensor) 25A with thermistor 44.In other words, triode ac switch device 72, circuit 73, control module 74, buffer 75 and resistance 76 are included among the control module 50 of Fig. 1.In addition, in Figure 12, be provided with sensor 38A, sensor 25A and receiving element 25B, but also can be same as in figure 1, adopt detecting unit 38 to replace sensor 38A.Also can adopt detecting unit 25 to replace the combination of sensor 25A and receiving element 25B.
Be input to control module 74 from the signal of sensor 25A, thermistor 44, sensor 38A and circuit 73 outputs, control module 74 utilizes this signal input to calculate the control signal of heater 29 and output to buffer 75.Heater 29 carries out switch control by triode ac switch device 72, is applied in AC100V voltage and the output of definite heater 29.
Herein, sensor 25A utilizes the current pyroelectric infrared sensor human body, and should check that signal finally sent to control module 74.Signal from sensor 25A is received by receiving element 25B, is input to control module 74.
In this formation, sensor 25A human body, control module 74 beginnings are carried out temperature control to heater 29 energisings according to the detection of thermistor 44, triode ac switch device 72, the power of control input heater 29.Therefore, can accomplishedly have warm performance of wink, easy to use, the heating toilet seat of the heating toilet seat that energy saving is good.
Figure 13 is the state transition diagram of control of the formation of Figure 12.In holding state 77, because signal does not output to triode ac switch device 72, so do not drive heater 29.High output state 78 times, always to 72 outputs of triode ac switch device, so heater 29 is driven by specified output.Low output state 79 times, discontinuously to 72 outputs of triode ac switch device, so heater 29 is by the output driving that is lower than specified output.
Turn to path (path) 77A of high output state 78 from holding state 77, when having carried out human detection, carry out, carry out when being higher than predeterminated level and become in the temperature detection of thermistor 44 to the path 78A of low output state 79 from high output state 78 by sensor 25A.From hanging down the path 79A that output state 79 turns to holding state 77, when detecting human body, the output from sensor 38A do not carry out.Such as, have the occasion of the luminescence unit and the light receiving unit of infrared LEDs at sensor 38A, when taking one's seat, detected by light receiving unit owing to come the light of selfluminous cell to be subjected to the human body reflection in the present portion 22 of human body, sensor 38A just detects and takes one's seat.When human body left portion 22, because detect light less than reflection at light receiving unit, sensor 38A just was judged to be nobody and takes one's seat.In the occasion of utilizing human detection unit 38, do not give unnecessary details because narrated.Like this, the heated condition that correspondingly changes heater 29 with the conversion of user's state is preferred.
Figure 14 is another state transition diagram of control of the formation of Figure 12.Turn to the path 77B that hangs down output state 79 from holding state 77 with the existence that is not both of Figure 13.When carrying out human detection in holding state 77, if the output of thermistor 44 is higher than predeterminated level, the temperature that is judged as a portion 22 is high, just to low output state 79 conversions.By path 77B is set, under using or the like when seat portion 22 is heated or the like situation continuously, can prevent to supply with unnecessary power to heater 29, can realize the warm toilet seat of wink of energy saving excellence.
Figure 15 is the control impuls of the triode ac switch device 72 in the control of the formation of Figure 12 and the sequential chart that heater applies voltage waveform.When gate pulse 80 of output, in the half period at next zero point, heater 29 is being applied voltage.When not applying gate pulse 80, on heater 29, do not apply voltage.
One example of the sequential chart of the gate pulse when Figure 16 is the high output state 78 of Figure 13, Figure 14 and the rising in the low output state 79.In high output state 78, the number of the pulse 81 that applied at interval every 0.1 second increases progressively, output maximum number after 1 second (12 pulses/0.1 second).In low output state 79, the number of the pulse 82 that applied at interval every 0.1 second increases progressively, and exports fewer purpose pulse (3 pulses/0.1 second) after 0.2 second in per 0.1 second.In other words, 1/4 of the high output state 78 of supply power in low output state 79.The umber of pulse of this low output state 79 can be set arbitrarily corresponding to specification, the design temperature of heater 29.
Figure 17 illustrates the interface circuit figure of human detection signal till being input to control module 74 that sends from sensor 25A, this circuit, such as, be included among the receiving element 25B.And Figure 18 illustrates the voltage oscillogram of each circuit block.
From the signal that passes through modulation of infrared rays that sends to receiving element 25B with infrared ray of sensor 25A, receive by infrared ray photo detector (below be called element) 83, size is consistent to be 5V., through negative circuit (below be called circuit) 84, integrating circuit (below be called circuit) 85, waveform shaping circuit (below be called circuit) 86 be input to control module 74, be judged as and carry out human detection thereafter.
The output signal 101 of element 83 is input to the grid (G) of the N-channel MOS FET transistor 87 of circuit 84.So output is relative between the resistance 88 and the ground that are connected Lou between (D) and power supply imports 0V and the anti-phase output signal 102 of 5V and is input to the circuit 85 of next stage.
In circuit 85, the resistance 89 about 1M Ω, with resistance 90 and diode 91 parallel connections about the mutual 10M Ω that connects, and capacitor 92 between discharge and recharge.Because the polarity of diode 91, the charging of capacitor 92 is mainly undertaken by resistance 90, and discharge is carried out through resistance 89.So the charging of capacitor 92 is fast, and discharges,, need 10000 times time approximately owing to be the resistance ratio that depends on resistance 89 and resistance 90.Therefore, the output when pulse is imported continuously rests on about 4V, and turns back to 0V when not having input.
Figure 19 is a flow chart of judging human detection in control system 74.In S001, will the flag F ind that signal is counted be resetted.Then, inspection has or not human detection signal (S002).During no signal, flag F ind is resetted (S003), enter idle condition and wait for interruption, in generation, have no progeny and just enter into S002.When the human detection signal is arranged, just on flag F ind, add 1 (S004), whether check mark Find becomes 12 (S005).If flag F ind does not reach 12, just enter idle condition, and reaching at 12 o'clock, enter into the routine after the detection with regard to finishing human detection.
The interruption of this routine owing to be to use zero signal of handing over from the AC100V of the 60Hz of circuit 73, was interrupted every 120 seconds.Therefore, for judging the human detection signal, must between 1/120 * 12=0.1 (second), export the human detection signal.In other words, control module 74 when sensor 25A repeatedly sends the human detection signal in the given time, is just judged to detect human body.So, even because noise has the short time superimposed pulses on circuit, also can prevent the flase drop survey, can realize the human detection that reliability is high.
The wireless receiving and dispatching mode of the signal between sensor 25A and receiving element 25B also can be carried out with energy-conservation wireless mode.In this occasion,,, the free degree at position can improve so being set because in the scope of seeing, there is not R-T unit also passable.Therefore, sensor 25A is arranged on toilet outside, such as, be arranged on place's detection staff such as front and push, rapidly toilet seat is heated or the like, can further improve heating properties.
In addition, when using infrared mode,, also can save the space because can not need to be provided with in addition receiving system with infrared remote controller and receiving system by the wireless of shared heating toilet seat.No matter what, by between sensor 25A and receiving element 25B, the free degree of design being improved with the wireless mode receiving and transmitting signal.
In addition, shown in the pie graph of Figure 20, on the basis of the formation of Figure 12, also can be provided with and have the switch 105 of indication the infrared ray transmitting element of heater 29 energisings.In the formation of Figure 12,, only utilize the human detection among the sensor 25A to carry out to the energising of heater 29.On the other hand, in the formation of Figure 20,, can indicate energising at any time by increasing switch 105.Such as, be the free degree of guaranteeing to install, when the power supply of sensor 25A was battery, the output of battery sometimes reduced and can not carry out human detection.In this kind occasion, can utilize 105 pairs of heaters 29 of switch to switch on.In addition, even sensor 25A and switch 105 and deposit also and can any influence not arranged to the thermal control that adds of seat portion 22.
As mentioned above, utilize the output of circuit 73, sensor 25A, thermistor 44 and sensor 38A, control module 74 output triode ac switch devices 72 drive the gate pulse of usefulness.Utilize this formation, can carry out and when detecting the human body that will use heating toilet seat 11, begin to be incubated at a certain temperature, and when the use of heating toilet seat 11 finishes, to cut off a series of flow processs the energising of heater 29 to heater 29 energising.Therefore, can obtain easy to use, the heating toilet seat that energy saving is good.
Below to relating to the detailed formation of control module 50, to be used to control utilize heater 29 the formation that rises of the temperature of seat portion 24 describe.In addition, basic formation is identical with Figure 12.
In this formation, as previously mentioned, sensor 25A detects human body, and heater 29 is begun energising.In addition, before heater 29 is begun to switch on, utilize thermistor 44 to detect heater 29 temperature on every side, determine heater 29 is applied the application time of initial voltage.
The environment temperature of the heater 29 also environment temperature with seat portion 22, main part 21 is relevant.Therefore, preferably with utilize thermistor 44 detected temperature correspondingly, when temperature is low, prolong application time to the initial voltage of heater 29.And, preferably when temperature is high, shorten application time so that the change of the relative environment temperature of temperature of seat portion 24 also keep necessarily as far as possible.Perhaps, as shown in Figure 1, control module 74 also can utilize thermistor 48 to detect environment temperatures and control application time to the initial voltage of heater 29.In other words, thermistor 48 is also nonessential, can detect environment temperature by dual-purpose thermistor 44, simplifies with reference to making to constitute by carry out temperature with suitable timing.
Figure 21 is the curve map of relation that the voltage application time of the detected temperatures of thermistor 44 and heater 29 is shown.Because the power of heater 29 is 600～800 watts, heater 29 even temperature is near during 0 ℃ severe winter around, also can be being incited somebody to action seat portion 24 and is being heated to the degree of not feeling cold by being less than the heating that equals 10 seconds.On the other hand, temperature surpasses 30 ℃ summer around, and heater 29 even heating is less than equaled 1 second or do not heat also to keep a portion 22 comfortable.In addition, when unmanned the use, heater 29 is not switched on.In other words, control module 74, during more than or equal to predetermined temperature, the cancellation initial voltage applies in the detected temperatures of thermistor 44.Can suppress unnecessary heating thus.
With the corresponding voltage application time of the detected temperatures of thermistor 44 to heater 29, such as, can be that unit sets application time with the second to each interval with per 5 ℃ of divisions, application time becomes the function of temperature.When this application time is essential, can utilize the zero cycle unit of handing over (when 60Hz is 8.3 milliseconds) to set as the industrial frequency of the unit that can control triode ac switch device 72.
Sometimes the detection of the temperature-detecting device of good, the thermistor 44 of the warm performance of the speed of heater 29 etc. postpones.Therefore, can not control rapidly heater 29, and to 22 over-heatings of seat portion, be difficult to carry out the change control corresponding with environment temperature.In other words, low winter correspondingly setting when adding thermal output with environment temperature, when temperature uprises around, will over-heating.High summer correspondingly setting when adding thermal output with environment temperature, around during the temperature step-down, will underheat.Yet, in the present embodiment, be correspondingly heater 29 to be switched on temperature on every side by this way.Therefore, can obtain having warm performance of wink, easy to use, the heating toilet seat that energy saving is good.
Figure 22 is the curve map of another relation that the voltage application time of the detected temperatures of thermistor 44 and heater 29 is shown.Shown in Figure 22 is in the occasion of detected temperatures more than or equal to 30 ℃, and heater 29 is not carried out the situation that initial voltage applies.Like this, preferred temperature around is higher to a certain extent, apply before energising finishes at initial voltage, if by thermistor 44 detected detected temperatures more than or equal to predetermined temperature, just stop initial voltage and apply energising.In this occasion, by heater 29 not being switched on, can obtain easy to usely, energy saving is good, the heating toilet seat of excellent in safety.
Figure 23 is the pie graph of another control system of the heating toilet seat of present embodiment.With Figure 12 and Figure 23 dissimilarity be, thermistor 106 also is set outside thermistor 44, be used for measuring the temperature of seat portion 24.Thermistor 106 be for the temperature that makes seat portion 24 smaller or equal to 50 ℃, the output that is used for control module 74 subtend heaters 29 is controlled and the temperature detecting unit that is provided with.With 50 ℃ is that the upper limit is a basis, asks 10 men and women that receive investigation at take one's seat result's application form and definite of the toilet seat that remains on 50 ℃.In the occasion that is seated at the toilet seat that remains on 50 ℃, 10 philtrums have 9 people's answers not feel extreme heat, and another one people's answer is not to be to be impatient at.In addition, even be to take one's seat on 50 ℃ the toilet seat actually,,, also needn't worry to be scalded so the toilet seat temperature sharply descends because the thermal capacity of human body is big.Like this, when the detected temperatures of thermistor 106 is higher than uniform temperature, because not to heater 29 energisings, so can suppress superheated.In addition, at this moment, control module 74 also can be controlled with reference to the temperature of thermistor 44.
Figure 24 illustrates heater 29 is applied power over time.Supply with heater 29 supply power after 6 seconds of 800 watts initial power and change into 200 watts,, just continue to be incubated facing to seat portion 24 with 200 watts power as long as the user is sitting in the portion 22.Thermistor 44 is also proceeded temperature detection when insulation, and stops power supply when surpassing design temperature.In other words, carry out conducting/disconnection work in when insulation repeatedly according to the output of thermistor 44 to heater 29.So the power during insulation is as long as more than or equal to the necessary power of insulation, can at random set.Power during this insulation can be according to the specification of heater 29, the umber of pulse that design temperature is set triode ac switch device 72.In addition, the control temperature of the control temperature in this when insulation during with initial power supply is different, and setting becomes long-time temperature comfortable when using seat portion 22.In other words, control module 74 after initial voltage applies the energising end, changes the control temperature that the applying power of heater 29 is changed heater 29.Utilize such formation, can prevent to supply with unnecessary power to heater 29, what can obtain the energy saving excellence can instantaneously heated toilet seat.
