Description
Technical field
The present invention relates to for example improvement of family expenses kettle and water heater of electric water heating vessels, the present invention is specifically related to a kind of structure, utilizes this structure being lower than the power supply that cuts off this container under the water temperature of boiling temperature, or reduces its power delivery.
Background technology
In this container, well-known steam control device, this device is used for when the water boiling of container, cut off the power supply of the heating of boiling water container, or reduce the output of its power, and sort controller is generally operated by the steam that produces during the water boiling in the response container, and the steam of discharging in the container enters into the container area of placing the thermoswitch actuator, in this zone, a general configuration is bimetal piece or have the device of SME for example.Become known for also generally preventing that the boiling water container heating element from overheated controller taking place, this overheated owing to electrical condenser is connected with the mains or dryouied and causes, sort controller generally comprises the bimetal release actuator, and this actuator can closely contact with heating element and can operate under certain overheated temperature through overcorrect.
Also propose a kind of water heating vessels that a kind of device is housed, the hot water that utilizes this device can provide temperature to be lower than boiling temperature is so that for example make coffee.A kind of electronic-controlled installation has been proposed, utilize this device, the user can select the temperature of the hot water of water heating apparatus generation, known bimetal piece structure, the class of operation of this structure is similar to a kind of adjustable thermostatic device, wherein the operating temperature of bimetal piece can be controlled by the user, and perhaps this bimetal structure can be regulated by the heat transfer relation that changes between heating element and the bimetal piece, for example regulates by moving bimetal piece with respect to heating element.
The bimetal piece that is used in water heating vessels in the controller is general now with stress snap action type bimetal piece, because this bimetal piece has very definite stable properties in time course.Using so-called creep effect type thermometal in the past, but use seldom now, mainly is because it lacks stable operating characteristic relatively.Creep effect type bimetal piece shows as the little by little crooked or distortion with the increase of temperature, different with snap action type bimetal piece, snap action type bimetal piece shows as when reaching predetermined temperature from a steady state (SS) and changes to another state, yet creep effect type bimetal piece can be used on the aspect that needs the adjustment control operating temperature.It is very disadvantageous that yet application creep effect type bimetal piece is come the direct control switch contact, because the motion of bimetal piece is slow (comparing with snap action type bimetal piece) quite, to on switch contact, cause electric arc, produce disadvantageous consequence thus, when in the controller of reality, proposing to use creep effect type bimetal piece for this reason, best design proposal is that the switch contact of bimetal piece and controller is separated, method is to utilize for example eccentric self-lock rod of snap action mechanism, and this snap action mechanism can become the slow movement conversion of bimetal piece the quick operation on the switch contact.For regulating temperature, it is adjustable that the mechanical relation between creep bimetal piece and snap action mechanism makes.
A kind of aforesaid this structure is proposed in Strix Limited ' s GB-A-2 329 523.The U18 type controller of the standard that can buy from Strix company has the creep bimetal piece now, this bimetal piece riveting is on the metal carrier band plate of controller, and can utilize manual selector to be configured to and can to interact with the trip(ping) lever of controller, this manual selector can be used for regulating the mechanical relation between creep bimetal piece and the trip(ping) lever.The structure of GB-A-2 329 523 makes the U18 type controller have extra maneuverable regulating device, so that be lower than the power supply that cuts off heating element under the temperature of boiling temperature, this temperature can be selected by the operation manual selector according to the correction and the adjusting scale of creep bimetal piece.
Because above-mentioned reason, according to our suggestion, it is a kind of not so good parts that the creep bimetal piece is used in the controller of boiling water equipment.Need make the initial temperature of certain form during manufacture proofreaies and correct according to the characteristic of creep effect type bimetal piece, can see, the embodiment of explanation comprises a set screw in GB-A-2 329 523, must regulate this screw so that determine the action of creep bimetal piece.So just, increased cost, and made controller very sensitive, changed because proofread and correct and regulate with the aging of controller for the variation of operating temperature.
Summary of the invention
Therefore, the controllability that the purpose of this invention is to provide water temperature, controller can be operated under this temperature, cuts off the power supply of boiling water container heating element, or reduce the power of heating element, do not cause among the above-mentioned GB-A-2 329 523 intrinsic shortcoming in the description architecture simultaneously.
Though the structure of GB-A-2 329 523 is not limited to the electrical heating elements of any particular types in its application facet, now, it at most still is used on the electric kettle and water heater that utilizes so-called thick-film heating element.Thick-film heating element comprises flat substantially matrix, this matrix is generally with for example stainless steel making of metal, but also not necessarily make with metal, on at least one side of this matrix a printing of carrying or with the heating path or the zone of heating of other method formation, can dispose electric insulation layer between heating path or zone of heating and matrix if desired, this electric insulation layer can cover heating path or zone of heating.According to one aspect of the present invention, we propose to use the operating temperature adjustability that characteristic intrinsic in the thick-film heating element reaches the thermally-responsive controls that is associated with thick-film heating element.Specifically be, we propose the alternative thermal output of regulating the thick-film heating element predetermined portions, and this predetermined portions has the thermal sensor that is associated with it, thus can be with respect to the operating performance of the corresponding change sensor of the volume that adds the water of pining for.
According to one aspect of the present invention, the electricity water heating vessels has thick-film heating element, thermally-responsive controls is configured to and can carries out thermo-contact with the predetermined portions of thick-film heating element, and disposes a kind of device, makes the thermal output of can selectivity regulating this part thick-film heating element.
The manufacture method of thick-film heating element generally is to have one or more layers normally on the matrix surface of the insulation course of glass with what conductive ink was printed on that stainless steel makes.On the element of this printing, the path temperature is relevant with water temperature, and under normal circumstances, the path temperature surpasses water temperature, and the amount that surpasses depends on the power density of path and the thermal conductivity of matrix and insulation course.The X4 type controller that illustrates in GB-A-2 339 088 patents that we propose is configured under the situation of 2.5-3kW heating element, and the path temperature is about 160 ℃, promptly is higher than 60 ℃ of water boiling point temperature.For fear of the trouble trip operation of controller between boiling period, the bimetal piece of controller generally is set in 180 ℃.If thermal output increases on the path part of heating bimetal piece, just the trip operation that when water temperature is lower than boiling temperature, bothers of bimetal piece then.If the extra quantity of power that is added on this part path is made to and can controls, then can control the temperature of controller " trouble tripping operation ", just water is under the controllable temperature that is lower than boiling temperature.When being applied to cordless container,,, as relevant cordless container is from its base, walks and reset so controller keep to disconnect because modification controller X44 (locking) has the locking effect.On modification controller X46 (Automatic Cycle) or X48 (Automatic Cycle with fuse), controller is with cycling, thus the temperature that keeps water being scheduled to.Certainly the present invention is not limited to use our X4 series controller.
The device that is used to regulate the thermal output of path below the bimetal piece can have some kinds of forms, but preferred form is to detect the position of heter temperature in bimetal piece, removes main the heating the path and adds auxiliary path.Can control the electric current that flows through auxiliary path, method is to make this path be connected in power supply through variable resistor.Can expect that the temperature of outage point descends about 20 ℃ the time, need the power of about 20W.The practice is, disposes a variohm, and this resistor separates with heating element, and has the manipulable control knob of equipment end user, but this resistor is worth high and can distributes a large amount of heats, thereby and uneconomical.Controller can be an electronic controller, because the controller of 20W power can just can satisfy well with parts at a low price.Yet best selection is to form variohm on thick-film heating element, form is the resistive trace that is imprinted on the heating element, dispose an arm that brush or slider are housed then, this contact is configured to and can be electrically connected on this resistive trace at any select location of path, or be electrically connected on any one contact of selecting in many contacts, these contacts are connected in the predetermined trajectories position, these positions unequal spacing that preferably separates each other, thereby when brush or slider move, the power generation linear change of auxiliary path, therefore this structure can increase or reduce the resistive trace length that is included in the auxiliary heater circuit.One " boiling " position also can be arranged, do not contact with resistive trace, and a setting that the auxiliary heater path is inoperative and container can boil water as usual is provided at this position slider.Yet this structure means that auxiliary path can not produce any heat when slider was in " boiling " position, and therefore there is not any contribution in this zone from well heater to total element power.This can not make full use of the available space of heating element, and cause the size and the cost of unnecessary increase well heater, for fear of this point, according to preferably configuration like this of the present invention, make " boiling " position on the whole resistive trace of circuit, and make that the power density of auxiliary path is identical with the power density of adjacent backbone line, thereby make the two at same temperature operation.The method of printing variohm path and slider is well-known, can be directly used in this kind structure.Resistive trace is preferably arc, and is concentric with element body dish (and/or electric equipment), and regulating arm can stretch out from the notch on the container main wall, is configured to slide along this main body.In addition, this arc can be shaped as and surpasses 180 ° minor diameter arc, and as mode common in the conventional potentiometer, in this case, travelling arm can rotate around arc core, and bar can be connected in travelling arm, and stretch out the side of slave unit.
Considering that using the X4 controller implements in the above embodiment of the present invention, the thermometal actuator of controller also can continue to dryout the effect of protector.If yet wish to use low power schemes more flexibly, the thermal sensor that the thermal sensor that can dispose provides on a kind of and the X4 separates.This sensor should have low thermal capacitance, to reduce the power that need obtain from the auxiliary heater path.When the applying electronic control system, can take the form of PTC sensor, or preferably a kind of little constant temperature contactor.This constant temperature contactor only needs the well heater path of less (on area) just can make its operation, because the temperature of well heater depends on its power density (not being absolute power), so little path only needs miniwatt.The temperature of constant temperature contactor is set and is about 105 ℃, with the tripping operation of avoiding between boiling period, bothering, it is adjustable that the auxiliary heater path can make, thereby reach the temperature rise between 0 ℃ to 65 ℃, make water selectivity to reach from being well suited for heating 40 ℃ of water temperatures of feeding bottle of baby to boiling temperature.The additional advantage of this method is that the auxiliary heater path is normally operated in very low power, or required power not, has so just limited the amount of incrusted deposit.This incrusted deposit that forms on main bimetal piece heater area causes working temperature to raise, and this may influence the cut-off point based on the temperature controller of main bimetal piece.At last, Here it is, and why bimetal piece is set to the reason that is higher than working temperature and avoids trouble and trip.
Another aspect of the present invention is used to keep water in predetermined temperature, for example keep simmer or keep water-bath setting low temperature, this has utilized disclosed principle in GB-A-2 248 114 patents that we propose on the other hand, this patent description how flow through bimetal piece self heating less than electric current and the temperature of regulating the bimetal piece controller is automatically again regulated again realize temperature controlling by guaranteeing that bimetal piece is differential.Under situation of the present invention, the heating be not by electric current provide but provide by the auxiliary heating path, it is differential that this heating evokes bimetal piece, until being disconnected, this path sharply drops to water temperature then, if this water temperature is lower than the temperature of the modification of bimetal piece, then controller is connected well heater, and repeats this circulation.This ringing is continuing always, thereby water intermittently heated, and reaches the temperature that bimetal piece is revised until water, and bimetal piece slowly circulates then, keeps well heater and water in the temperature of revising, described in patent GB-A-2 248 144.In order to make full use of this effect, the bimetal piece that preferably has a variable modification, promptly has the fixedly adjustable double metalwork of auxiliary rail linear heat generation rate, but variable modification (adjustable) bimetal piece can adopt adjustable auxiliary rail linear heat generation rate to use, in this case, regulating for example adjusting of auxiliary heating power for one during these are regulated can set in factory, other then be that user by electric equipment utilizes the controller that suitably forms on the electric equipment to regulate.For example utilize the adjustable retainer of bimetal piece and/or utilize the adjustable bimetal piece of stress can regulate bimetal piece modification temperature easily, regulate the modification temperature of considering to be used for implementing dish type snap action bimetal piece of the present invention especially easily.
In the enforcement of this respect of the present invention, controlled temperature can not be subjected to the influence of any sediment incrustation, because when controllable temperature, descends without any temperature on insulating medium/matrix/incrustation scale interlayer.Should be noted that the example for above-mentioned circular form controller X46, if use the normal modification temperature (this temperature is more than 100 ℃) of sort controller in implementing another aspect of the present invention, then water temperature will trend towards stable rising until boiling.For this reason, when needs kept controlled water temperature, preferably another kind of its setting of application and modification temperature were lower than 100 ℃ constant temperature contactor.
According to one side more of the present invention, the thick-film heating element of electricity water heating vessels has predetermined portions, this predetermined portions has auxiliary heater, and snap action type bimetal piece drive configuration becomes and this part generation thermo-contact of heating element, the thermal output of above-mentioned auxiliary heater is depended in its operation when making application, and it is adjustable that above-mentioned snap action type thermometal actuator is revised temperature with regard to it.
Can disconnect the electric equipment of boiling with any known mode, for example can be respectively with we patent GB-A-2 212 664 and GB-A-2 331 848 in the J1 or the Z5 controller of explanation, or utilize the principle that illustrates among the patent GB-A-2 265-070, or by detecting the ascending velocity of water temperature, as our electronic kettle controller of explanation among the GB-A-2 228 634, disconnect electric equipment.
According to the feature that another can select of the present invention, thick-film heating element has auxiliary heating path and a kind of device, this auxiliary heating path is positioned at heat controller for example bimetal controller and the juxtaposed position of heating element, this device can be regulated the thermal output of auxiliary path as mentioned above, in addition, this thick-film heating element also additionally has the insulation path and can regulate the device that is incubated the path thermal output.The device of regulating auxiliary path and the thermal output of insulation path is preferably shared, make same manual operation just can carry out two kinds of functions, this shared device preferably includes juxtaposed each other separately variable resistor element, these resistive elements are arranged in and can utilize same slider controller to regulate, the slider controller preferably has open position, when open position, do not contact, so the equal inoperation of auxiliary heater or muff heater with two variable resistor elements.
Water heating vessels has the heating element protection controller X4 of the state of this heating element and monitoring heating element; one of its thermometal driver is configured to respond the heat that is produced by main heating element path and auxiliary path; and another thermometal actuator is configured to respond the heat that is produced by main heating element path and insulation path; this water heating vessels has ON/OFF controller and another controller that is made of above-mentioned slider; this ON/OFF controller by the boiling point monitor controller for example the by-pass cock again of our above-mentioned J1 or Z5 steam controller constitute, or this water heating vessels preferably has two this shared each other controllers.Have the path of suitable configuration and this water heating vessels of bimetal piece and can have different operator schemes, that is: water boiling mode, in this pattern, the slider controller is in open position, thereby auxiliary heater path or the equal inoperation of insulation path, and container is controlled by operation boiling point detecting device; Boil water and the insulation pattern, in this pattern, the slider controller is configured to make the insulation path that maximum power output is provided, and auxiliary path provides minimal power output, water in the container at first is heated to boiling by operation primary heater path thus, this container is disconnected by Z5 steam controller then, is incubated path subsequently and keeps water in the container near boiling point; Heating and insulation pattern, in this pattern, the slider controller is positioned at the centre position, make when the water in the container reach certain selection be lower than the temperature of boiling temperature the time, the power supply of main heating element path is cut off in auxiliary heater operation, is incubated path then and keeps water in the container in chosen temperature.Select appropriate mode, can obtain boiling water from this water heating vessels user, or opened but near the water of boiling temperature, or only be heated to the water of certain selected medium temperature, the selection of pattern is simple and uncomplicated.

Fig. 2 illustrates thick-film heating element shown in Figure 1 in the electrical heating boiling water container, and this container has dual for example our above-mentioned X4 controller and steam controller our above-mentioned J1 or the Z5 controller for example of dry combustion method controller that prevent.In this figure, two dry combustion method controllers are represented with numbering 21 and 22, and be designed to aim at the zone 7 and 8 of thick-film heating element, the steam controller is designated by numeral 23, the control position that does not contact the slider 14 of foxy path 13 is designated by numeral 24, this position of slider is used for separating with auxiliary heater path 11, thereby container can be used as the container operation that boils water.
Fig. 3 illustrates another thick film path planimetric map, special and our the modification controller logotype of the following X4 controller that will illustrate of this planimetric map, adopt and the identical numbering that before was used among Fig. 1, the thick-film heating element of Fig. 3 has zone 7 and 8, this zone design becomes to aim at the bimetal piece of X4 controller, zone 7 has the auxiliary heater path 11 that is associated with it, this path is connected in path part 13, this path part 13 is designed to and 14 co-operatings of controller slider, thereby form a variable resistor, the container user can be by the heat output of the auxiliary path 11 of this variable resistor control.
The X4 that Fig. 4 A～4D illustrates remodeling is fixed on as shown in Figure 3 the thick-film heating element.Fig. 4 A only illustrates the zone of the heating element that needs the alignment controller specific part, promptly in zone 6, the installation foot of controller metal underframe is fixed on the metallic matrix 1 of heating element, and in zone 7 and 8 the bimetal piece thermo-contact heating element path of X4 controller, the spring terminal of X4 controller can electrically contact the heating element path on terminal area 9 and 10, and variable resistor path part 13 is suitable for contacting the control slider of X4 controller.
Below with reference to Fig. 4 B, this illustrates the X4 controller 40 of the remodeling that is fixed on the heating element.As everyone knows; described in above-mentioned GB-A-2 339 088; the X4 controller comprises the cordless container input pad 41 of the 360 degree types that we invent; this web member makes cordless container can be contained on its base from below; can be positioned at any orientation in relative rotation; and form one with container; first and second heating elements protection controller is generally represented with numbering 42 and 43; they are subassemblies of bimetal piece or a bimetal piece and a fusible material, as what illustrate in our above-mentioned application.On the position 44 of controller, Z5 steam controller can be fixed in the X4 controller.
Fig. 4 B, 4C and 4D illustrate the modification of X4 controller.The underframe of controller has extension 51, and this extension has the centrally-pivoted axle hole 52 that is positioned at arch section 53 arc cores, and end stop 54.Plastic mould 59 has pivot pin 56 and overlapping arm 57, and is designed to can quick-snap in placely, as shown in the figure, makes pivot pin 56 be positioned at the pivot hole 52 of underframe extension.Overlapping arm 57 be contained in metal underframe extension below break away from its pivot so that prevent moulded parts, this overlapping arm plays guide when moulded parts rotates.In the outer end of moulded parts is the cassette portion 58 with Fast Installation lid 59.Carbon brush component 60 is embedded in the cassette portion, this brush reaches the heating element surface, the braided wire of brush part has fixing quick connect receptacle, this socket can be connected on the plug 61 of X4 controller, this plug is connected in the zero line supply terminals of heating element by the dry combustion method heat controller of neutral side, shown in the circuit diagram of Fig. 2.
Also can from the circuit diagram of Fig. 2, find out, the boiling point control device will work to cut off the heating element power supply, it does not rely on the connection of brush assembly, this boiling point control device can directly insert X4 maybe can be installed at a distance (situation as shown in the figure, this controller can be inserted on the isometric view with in numbering 62 and 63 sockets of representing).Can guarantee so just that when the low temperature component failure takes place the anti-sealing of boiling controller total energy seethes with excitement continuously.
When the X4 controller was contained on the heating element, carbon brush contacted with the foxy path 13 of arc, the angle that the angle of rotation of moulded parts faces toward greater than this slippery fellow's path, thereby in an end of stroke, this carbon brush does not contact this slippery fellow's path.In this position, auxiliary heating path 12 no powers, and also electric equipment can be operated as normal automatic electric heating kettle." boiling position " among Here it is Fig. 2.Electric current will flow through auxiliary path when carbon brush contacts foxy path, this moment as mentioned above, depend on the power in the auxiliary path, the bimetallic strip that dryouies of phase line side will be at certain temperature operation, the position of change carbon brush on foxy path will change the power of auxiliary path, therefore change the water temperature of controller deenergization.
Fig. 5 and 6 illustrates another thick film path planimetric map, and this path is designed to the X4 controller logotype with above-mentioned remodeling.The numbering that adopts among Ref. No. and Fig. 1 and Fig. 3 is identical, the thick-film heating element of Fig. 5 and Fig. 6 has zone 7 and 8 respectively, this zone design is for aiming at the bimetal piece of X4 controller, zone 7 has the auxiliary path 11 that is associated with it, this path is connected in path part 13, this path partial design is the control slider co-operating with the X4 controller, thereby forms a variable resistor, utilizes this variable resistor container user can control the heat output of auxiliary path 11.
In two heating element planimetric maps of Fig. 5 and Fig. 6, main power path is wideer, and the auxiliary path 11 of temperature control is then narrower a little, because this path is lower powered, and has higher resistance.Arc control trajectory 13 separates formation with slidding carbon brush contact path, and has the silver web member 14 ' of a series of being printed thereon (or it down).This silver web member leads to the very near silver pad 15 of a series of spacings, and this silver pad is positioned on the arc below the carbon brush contact path, and the spacing of this pad can guarantee that carbon brush always can contact two pads and these two pads of bridge joint, reduces contact area hardly.
Another feature of Fig. 5 and Fig. 6 design is not have carbon brush to break away from " boiling point " position of arc path, and this position means on auxiliary path and do not produce heat, thereby total heater element power do not made contributions from that part of zone of well heater.So just, can not make full use of available space, cause the unnecessary increasing of well heater and increase cost.In this planar design, in " boiling point " position that comprises whole arc length, the power density of auxiliary path is designed to the same with the power density of adjacent main power path.Therefore, the running temperature of auxiliary path is the same with the running temperature of main boiling path, can not cause the tripping operation of trouble, has both helped the normal power output of heating element, can make the bimetallic strip in this position carry out necessary dry combustion method response again.According to the present invention, when carbon brush moves on to minimum arc length, the power density of auxiliary heating path will increase, and cause bimetal piece to start under the temperature that reduces gradually.
Below with reference to Fig. 7, the embodiment of the another thick-film heating element of the present invention shown in the figure, this thick-film heating element also is equipped with the insulation path and relevant can regulating is incubated the controller that the path heat is exported except that auxiliary path and the relevant foxy path of the arc that can regulate auxiliary path heat output are housed.The controller of insulation path and the controller of auxiliary path are actually total, because the foxy path of the arc of insulation path is parallel to the foxy path and concentric with this path of arc of auxiliary path.And adopt same controller to determine the position of each carbon brush relevant with the foxy path of each arc.Be described in more detail as following, this configuration makes hot-water bottle or water heater for example can selectivity provide boiling water, the water that perhaps provides its temperature of having opened to approach boiling point perhaps provides and has been heated to the water following temperature of boiling point and that remain essentially in this temperature.In addition, the configuration that the following describes can only manually be controlled device with one and reach these functions.
Adopt among Fig. 7 with previous embodiment and represent same parts with the identical numbering of crossing.As shown in the figure, thick-film heating element 1 has arc primary heater part 4, and the end of this part 4 is connected in conductor 5, and to avoid current concentration, this primary heater path extends between zero terminal and phase terminal 9 and 10 respectively.Auxiliary path part 11 be connected the tapping point 20 of primary heater path and the adjustable resistance that forms by path part 13 between, this tapping point 20 is selected as partly adding to auxiliary path the low supply voltage of requirement, and this adjustable resistance has the tapping point 15 of relevant contact 14 ' and alternative contact slidding carbon brush contact.As shown in the figure, form end tapping point 15 ', the carbon brush contact can be parked on this tapping point and break away from and the electrically contacting of path part 13; When the carbon brush contact is positioned at this position, auxiliary path part 11 no powers.
In heating element, be formed centrally extra path part 21 as the insulation path.As shown in the figure, one end of insulation path 21 is connected in the additional power supply terminal 22 that forms on heating element by lead 23, and its other end is connected in another adjustable resistance 25 by lead 24, this adjustable resistance structurally is similar to, and is being parallel to the adjustable resistance relevant with auxiliary path part 11 in shape.Disposing parallel in shape apart very near adjustable resistance makes and can operate two adjustable resistances with same control sliding part.
The controller that is used on the heating element shown in Figure 7 is the modification controller of the X4 controller of earlier in respect of figures 4A～4D explanation.According to this modification controller, the slidding carbon brush mechanism of Fig. 4 scheme has two separately carbon brush (the perhaps single brush of a broad) that are connected in flexible circuit conductor or braided wire, and standard x 4 latches that this flexible circuit conductor utilization provides for this purpose and plug are connected in a terminal of boiling controller 25.Modification controller X4 also has the 3rd spring contact 22 except that the phase line of standard and center line contact, this contact is positioned at the next door of auxiliary path 11.Fig. 8 illustrates controller and how to be connected in heating element and how to interact with this element.
Controller is equipped with high temperature bimetallic strip (180/190 ℃) in the center line side, is used to protect backbone line and auxiliary path.Low temperature bimetallic strip (110/120 ℃) is contained in the phase line side, plays the insulation on-off action, constitutes second protection.The pot slider has one or two contact (depend on design, should guarantee that two resistive trace have excellent contact pressure), and two variable resistor paths of this contact contact make that another reduced when a resistance increased.End in slippage has the isolated location, plays " disconnection " effect.Auxiliary path 11 shown in the figure is from the tap power supply of backbone line part path, and its supply voltage is lower, is well suited for being used to print the used resistance material of well heater path.This is for convenience, and if desired, auxiliary circuit also can be powered with whole supply voltage.
Heating element shown in Figure 7 can form following select operating mode when with above-mentioned controller coupling:
1. boiling: slider is positioned at open position, and kettle is connected by the Z5 controller, and this controller plays conventional effect, cuts off the power supply of kettle when water seethes with excitement.Because slider does not connect any path, so this contact is inoperative, thereby auxiliary path and the inoperation of insulation path.
2. boiling and insulation: slider is positioned at maximum position, and controller Z5 energized burns boiling with water, disconnects Z5 then.The slider of insulation path 21 provides peak power to this path, and this insulation path is designed to keep water temperature near its boiling point.The slider of auxiliary path 11 makes relevant well heater path obtain very little heat, and this is not enough so that the thermometal that combines with it (thermostat) operation.Operating Z5 at any time can make water seethe with excitement again.
3. heating and insulation: the position of slider between minimum and maximum, when the Z5 energized, the backbone line adds hot water, up to auxiliary path 11 thermometal of thermostat is tripped.After this be incubated the temperature that path 21 keeps water.Dispose two variohms, make that " insulation " sets " alternating temperature " setting of deferring to by auxiliary path 11 decisions when slider moves, thereby the temperature that keeps is near the alternating temperature temperature.Clearly, depend on the water yield in external condition and the kettle, the insulation path can make temperature that some variations take place, and reaches the temperature that certain low slightly alternating temperature path obtains temperature so path preferably always is decided to be.This means that the thermostat thermometal will circulate frequently, if desired, make the main circuit circulation, make water temperature get back to required value.The possibility that can avoid water temperature slowly to rise in uncontrollable mode like this, the while can be limited the rate of circulation of thermostat, increases its uptime.
The dry combustion method thermometal of X4 can be prevented the dry combustion method of locking system, and this thermometal is configured on the zone 8 of heating element.This will cut off the backbone line, if but slider not at open position, then be incubated path 21 still keep the energising.Insulation path 21 is positioned at the center, thereby the heat that can guarantee it can not damage capsul or chamber wall.Just in case when the dry combustion method bimetal piece is malfunctioning, will operate, but because trace watt density is low, therefore operation can be slow with other bimetal piece that auxiliary path 11 is associated.Even slider is positioned at open position.But can send enough heats from the backbone line, set bimetal piece and can operate to guarantee this low temperature.If the insulation path keeps energising, then this path rises probably and makes the alternating temperature bimetal piece remain on mode of operation, similar manual lock bolt form, and this state can reset by the power supply that disconnects kettle., this action do not rely on the design of system yet depending on the position of slider.
The problem that the design of " user interface " is just selected.Form two controllers that separate, one is used for boiling control, and one is used for slider.Yet so still stay the difficult problem with two open positions, common end user not necessarily can expect disconnecting two controllers could disconnect electric equipment fully.Scheme is to form the single slip controller with following three kinds of states preferably: off-state, and Z5 and slider all are positioned at its " open position under this state; The boiling location status, under this state, Z5 can energized and can be returned the controller of " disconnection " state, and slider still remains on its " disconnection " position; Simmer position range state, under this state, the Z5 energized does not influence the control of sliding, and slider is between minimum and maximum.The state of electrical equipment is represented with pilot lamp.This mechanism is the mechanism that skilled Machine Design personnel know, and can utilize the wheeled effect of idle running effect and discontinuous operation.
Above with reference to customized configuration and exemplary embodiments explanation the present invention, but should be understood that and to carry out various remodeling and variation and do not exceed scope of the present invention.For example, according to the explanation of GB-A-2 340 367, the backbone line part 3 of thick-film heating element 1 can form and show PTC (positive temperature coefficient of resistance) feature, and auxiliary heater 11 can form and has the NTC characteristic, so that the compensation supply voltage changes.In addition, although in the above description, auxiliary heater is formed the integral part of thick-film heating element, and the present invention is applicable to that also control utilizes other type heating element of thermometal actuator.For example, according to explanation of the present invention, heating element under the plate face of the tinsel resistance-type that the inorganics that can utilize bimetal controller to control the metal jacket insulate, method is to form the independent auxiliary heater that closely contacts with bimetal piece, the variable resistor of for example little thick film heater and the output of configuration control auxiliary heater.The metal installing plate of X4 controller (for example parts 27 among the figure ID of GB-A-2 339 088) fully can be therein forms the little thick film heater of used as said purpose on that part of installing plate that extends below of bimetal piece.
