Description

The controller that is used for liquid heating apparatus

Technical field

The utility model relates to the controller that is used for the controlling liquid firing equipment, for example when water seethes with excitement off device or prevent overheated.

Background technology

Traditional kettle or water heater are equipped with the boiling controller, during the liquid boiling of said boiling controller in container operation lead to cut-out container well heater power supply and stop boiling.Similarly, can be provided at the heat controller of crossing of cutting off the electricity supply when well heater surpasses the safe operation temperature.

Usually, such controller uses the alcu alloy film spring as movably the contact is to set up or interrupting power circuit, and wherein flat spring transmits electric current, forms the part of circuit.Typically, flat spring works via push rod through heat-sensitive duplex metal actuator, operates during liquid boiling or the overheated heater of said heat-sensitive duplex metal actuator in container.

The utility model content

The purpose of the utility model provides the improved controller that is used for liquid heating apparatus.

When first aspect is seen; The utility model provides the controller that is used for liquid heating apparatus; Said controller comprises the switchgear that is used to set up or breaks off the circuit that is used to supply power to liquid heating apparatus, and said switchgear comprises: the fixed contact member; Be installed in the movable contact member on the switch lever; Be installed in the responsive to temperature actuator on the controller; Make when controller is installed on the liquid heating apparatus responsive to temperature actuator and liquid heating apparatus thermo-contact and to the responsive to temperature of liquid heating apparatus; The responsive to temperature actuator is set to act on the switch lever, makes that switch lever is removed the movable contact member from the fixed contact member when liquid heating apparatus reaches predetermined temperature; And elastic device, it separates with switch lever and acts on the switch lever, electrically contacts so that the movable contact member is biased to the fixed contact member.

Therefore; Should understand; The situation that is different from the device that adopts flat spring, such controller will have the mechanical property and the electrical characteristics of the structure of movable contact member separates because contact member be installed in can for rigidity (promptly; Self need not be elasticity) bar on, provide and be used for the elastic device of the required bias force of good electrical contact through the separation of for example spring.This makes it possible to select only material for each parts.Before because the biasing of removable electric contact and conduction through in the controller for example the same parts of flat spring provide, so when selecting employed material, need between the required functional characteristic of two different operation requirements, trade off.Advantageously can use the switch lever of rigidity, because this allows it to move, and therefore contact member mobile is predictable and is reliable.

Switch lever can be made of metal; And therefore can be set to self is sent to the movable contact member with electric current; But in one group of embodiment, bar comprises the for example insulating material of plastics, and it can easily be molded as desirable shape and avoid the demand with other part electrical isolations of bar and controller.Plastic bar also can help to reduce the cost of controller, because plastic bar has reduced the amount of metal of costliness of the for example copper of necessary use.For further increasing the security of controller, in one group of embodiment, the electric conductor of the for example line that leads to removable electric contact is carried in the switch lever of insulation.Therefore insulating bar is used as the sheath that is used for electric conductor, thereby is provided for conveying electrical current to the safety of removable electric contact and path easily.

The movable contact member can be along any direction, (action side-swip eaction promptly is close to) contact fixed contact member vertically or flatly for example, and therefore switch lever can be set to the movable contact member is moved along one in these specific directions.According to the direction that wherein is moved away from the end of movable contact member, this possibly require switch lever to have specific shape.

The fixed contact member can be arranged in the control module, for example typically is arranged in the utensil part of liquid heating apparatus.Yet in one group of preferred embodiment, it is arranged on the cordless base connector, for example as typically by that kind that base unit provided to the power supply of wireless liquid heat utensil.In other words, said movable contact member is arranged on the control module that is used for utensil, and said fixed contact member is arranged on the cordless base connector.This allows control module in the utensil part and the power supply between the wireless connector in the base unit are connected unlatching.This means, and between two wireless connectors part, have the contact, and compare, need less contact right at the conventional device that the controller of the utensil that is used for power switch that for example prevents the elements overheating also has a contact.This causes further practicing thrift cost.In addition; Because the switch lever in the controller of the utility model is flexibly setovered so that required contact pressure to be provided; So the contact of elastic biasing need be set in the cordless base connector, and this makes that it is firmer and has allowed effectively to make than cost, like what will explain below.

The cordless base connector is preferably permission and irrespectively sets up the type that is electrically connected, promptly so-called 360 ° of connectors substantially with the relative angle orientation between dock connector and the controller.Yet in certain embodiments, connector possibly not allow with respect to the orientation of controller complete 360 °, but still allow substantially with orientation irrespectively, for example set up and be electrically connected through 345 ° or bigger scope.

In the controller of the utility model; The switchgear of single said type can be set to for example be used for the only hot side of Switching Power Supply, and other electric contact that for example is used to be connected to neutral line terminal and ground wire terminal (under situation about providing) is connected through for example hardwire differently.Yet in one group of embodiment, controller comprises at least two such switchgears, for example is used for the switch live wire utmost point and the neutral line utmost point.

Under the situation that two switchgears are set, on each contact, provide the elastic device of bias force can comprise single spring.Yet, the spring that separates is provided in one group of embodiment.This makes each switchgear be easier to independent operation, for example through working with the responsive actuator of for example bimetallic independent temperature.

The movable contact member preferably includes the for example material of the good electric conductor of copper.In one group of embodiment, the movable contact member comprises silver coating or silver tip.Selecting silver is the electric conductivity of Yin Qigao; This has reduced the trend that surface in contact worsens owing to oxidation; But silver only provides as coating or at the tip, promptly is provided at the fixed contact member to carry out physics position contacting place, maximizes the validity of silver simultaneously with the cost that reduces the contact.Preferably the surface in contact of fixed contact member comprises silver similarly.Yet the applicant finds, when opposite side is copper, only on a side, uses silver, promptly on movable contact member or fixed contact member, uses silver that enough performances are provided.This is because the plasma that generates during the starting the arc when breaking off in the contact causes the silver-colored fusion on the contact, thereby causes silver layer to be deposited on the relative contact.

One group of embodiment of two movable contact members of the utmost point that for example is used for the switch separation is provided therein; In preferably said two contact members only one comprise silver coating or tip, that is preferably used for the switch live wire utmost point comprises silver coating or tip.In other words, the said movable contact member that is associated with the said live wire utmost point comprises silver coating or silver tip.Controller can be advantageously provided to making during normal use, at first make that the contact member that has silver-colored surface in contact is preferential and set up or the disconnection contact.This has maximized in a small amount, and the benefit of silver allows other contacts to not having silver simultaneously.

Be used for the elastic device of switch lever biasing can be comprised volute spring or flat spring, but in one group of embodiment, elastic device comprises wire spring, promptly make the line of certain-length along its length from its physical slot displacement to apply power in the direction opposite with its displacement.The manufacturing of wire spring is simple and cheap, and selects the material of the characteristic that can be hopeful from having, and for example has in the material of high strength, high elastic limit, low Young modulus and high cycles fatigue to select.For example, wire spring can comprise steel, because it has the characteristic that is hopeful.

As will recognize, for the desirable characteristic of spring needn't with for the movable contact member or to carry its desirable characteristic of bar compatible, especially needn't be compatible with material desirable characteristic cheap and that obtain easily.In addition, need not require spring to have any electric conductivity, for example spring can be formed by insulator, does not transmit any electric current because require spring.Similarly, needn't require the movable contact member to have any specific mechanical property for the necessary for example intensity of spring.Therefore, contact member can be formed by weak relatively material, and is for example extending so that form it into the material of the shape of requirement; Can be simply select to its conductive characteristic, but useful certainly be that this material also has other characteristic, when contact or the conductor that is associated move, be flexible for example.

In one group of embodiment, the surface that switch lever is flexibly setovered and pivoted above that against it.This has simplified design and structure from the lever apparatus of not expensive relatively plastics.Elastic biasing can provide through spring assembly independently, but in one group of preferred embodiment, this is through providing the identical elastic device of movable contact member to the biasing of fixed contact member.

As preferably; When liquid heating apparatus is so-called wireless type; When comprising the cordless base that is used to be connected to the power supply power supply with the suitable utensil that is used to match, the controller of the utility model can be arranged in the cordless base, but in one group of preferred embodiment; Controller mainly is in the suitable utensil, for example is electrically connected to electrical heating elements.Yet as previously mentioned, the fixed contact member of switchgear can be arranged in the cordless base connector, and the miscellaneous part of switchgear is arranged in the utensil part.Electrical heating elements will typically be set to and heated liquid thermo-contact well in equipment.Electrical heating elements can comprise the heating element that has sheath on the downside for example that immerse or that be installed in the heater plates on the liquid heating apparatus, or comprises thick-film heating element.

In one group of embodiment, controller comprises the sealing conductor that movable contact is connected with the terminal (cold lead that for example has the heating element of sheath) of heating element.Provide the electric parts of sealing to allow controller to be exposed in the water and do not have short risk.The sealing conductor can become one with switch lever, and the insulating bar of conductor for example wherein is provided, the security that gets into the waterproof of further improvement controller.

In one group of embodiment, controller for example comprises the actuator of user's operation of " close (OFF) " button, and its bias force that is set to resist elastic device moves out the movable contact member from the fixed contact member, be used for interrupting power circuit.Preferably, the actuator of user's operation acts on the movable contact member (if providing) that is associated with the live wire utmost point of circuit.In one group of embodiment, actuator acts directly on the switch lever.In one group of embodiment, controller comprises locking mechanism, and said locking mechanism is set to the movable contact member remained and leaves the fixed contact member, promptly when the actuator of user's operation acts on the movable contact member.This possibly be necessary, because in certain embodiments, the elastic device of biasing movable contact possibly be monostable, and promptly when the actuator of user's operation was released, movable contact will be setovered back towards the fixed contact member.Usually; Provide monostable elastic device to allow the better simply actuating mechanism and the cordless base mechanism of the actuator or the responsive to temperature actuator of use user operation as describing hereinafter; Because do not need further to move, for example for the situation of bistable or eccentric stiffener to set up contact once more.The actuator of other user's operation of the button of for example " opening (ON) " can be set to the movable contact member is discharged from locking mechanism.In one group of embodiment, " opening " and " pass " button can comprise link mechanism, and for example making once only has one can activated in them any.

Provide therein among one group of embodiment of wireless controller, controller preferably include the bias force that is set to when utensil is placed on the cordless base opposing elastic device with the movable contact member from mechanism that the fixed contact member is removed.In other words, said controller further comprise the said bias force that is set to when said control module is placed on the said cordless base connector, to resist said elastic device with said movable contact member from mechanism that said fixed contact member is removed.This has prevented for example to be used for liquid heated toppled over when being placed on the pedestal after utensil when utensil is being lifted, and utensil is by energising once more all of a sudden.The movable contact member is latched to it from position that the fixed contact member is removed in the time of can acting on above that in said mechanism; Perhaps said mechanism self can by locking, therefore remain the movable contact member and leave the fixed contact member through equipment being placed on the action on the cordless base.Yet preferably, when utensil was placed on the cordless base, the elastic device of said mechanism through for example wire spring was biased to said mechanism and the movable contact member remained the position of leaving the fixed contact member.In other words, when said control module was placed on the said cordless base connector, said mechanism was biased to said mechanism by said elastic device said movable contact member is remained the position of leaving said fixed contact member.The elastic device of said mechanism of setovering needn't directly be resisted the elastic device action of biasing movable contact member; Preferably, said mechanism is biased to it through elastic device and acts on the position on the movable contact member, makes that the movable contact member is removed from the fixed contact member when equipment is placed on the cordless base.Because the movable contact member is moved by said mechanism, therefore the action that utensil is placed on the cordless base can provide the bias force that overcomes on the movable contact member necessary power.In one group of embodiment, controller comprises the actuator of the user's operation that is configured such that said mechanism breaks away from, and for example " drives " switch.Its action is to be discharged from it movable contact member by the position that said mechanism is held open; Allow the movable contact member to set up again and the contacting of fixed contact member (but needn't force it so to do, for example act in the situation on the switch that resets not yet) at the heat-sensitive actuating device.

Controller is configured such that switch lever was removed the movable contact member when proper liquid heating apparatus reached predetermined temperature conditions from the fixed contact member.This can be the predetermined temperature that liquid in the equipment reaches for example boiling, or electrical heating elements reaches predetermined temperature, for example reaches indication boiling or overheated temperature.Controller comprises the for example responsive to temperature actuator of bimetallic actuator, and it is set to act on the switch lever.Preferably, the responsive to temperature actuator is installed on the outside surface of controller.Controller can comprise more than an actuator, for example comprises actuator and actuator that sensing is overheated of a sensing boiling.In one group of embodiment; Controller comprises the temperature-sensing device (being the boiling temperature sensing apparatus) of the boiling of the liquid in the tracer liquid firing equipment; The steam cock that for example can comprise bimetallic actuator; It is set to act on the switch lever, so that the movable contact member is separated with the fixed contact member.In another group embodiment that needn't mutual exclusion; Controller comprises the overheated temperature-sensing device (being the overtemperature sensing apparatus) of tracer liquid firing equipment; For example it can comprise the bimetallic actuator that is installed on the electrical heating elements or abuts against electrical heating elements; It is set to act on the switch lever, so that the movable contact member is separated with the fixed contact member.

Therefore can see that in a preferred embodiment, the responsive to temperature actuator of the bimetallic actuator of for example snap-action (" snap-acting ") acts on the switch lever with contact separation.At this, the attribute of bar can be utilized, and for example makes pivotal point near actuator but not the movable contact member promptly makes moving of actuator amplified by bar through the ratio that bar is set.Bar also can be utilized allowing and is exaggerated by the relatively little power that actuator was applied, and opens it with the high relatively bias force of opposing movable contact member, when the higher contact pressure of hope, needs high relatively bias force.This has produced the controller of safety; Because for example the relatively little travel distance of the actuator of the bimetallic actuator of snap-action can be enlarged into the bigger travel distance of movable contact member, guarantee to have enough separation to satisfy safety standard apart from the fixed contact member.

Be provided with one group of embodiment of two removable switchgears that for example are used for the live wire utmost point and the neutral line utmost point therein, controller preferably includes the independently responsive to temperature actuator that is set to act on each switch lever separately.Alternatively or additionally, controller can comprise the boiling that is set to act on the identical switch lever and cross thermal actuator.In most preferred embodiment group; Controller comprises the overheated independently responsive to temperature actuator that is used for the tracer liquid firing equipment; Said responsive to temperature actuator be set to act on respectively with the live wire utmost point and neutral line utmost point associated switch bar on; And controller comprises the actuator of the boiling of the liquid in the tracer liquid firing equipment, said actuator also be set to act on live wire utmost point associated switch bar on.

As previously mentioned, when thermal actuator being set extremely going up to act on the live wire utmost point and the neutral line, the actuator that is associated with the live wire utmost point preferably is set to preferentially during normal use at first action, and for example the firewire contact member has silver-colored surface in contact because this only allows.This for example can realize near heating element through the responsive actuator of overtemperature that the responsive actuator of the overtemperature that is associated with the live wire utmost point is set to than is associated with the neutral line utmost point.In one group of embodiment, the responsive actuator of the overtemperature that is associated with the live wire utmost point comprises the bimetallic actuator that is installed on the heating element.In one group of embodiment, the responsive actuator of the overtemperature that is associated with the neutral line utmost point comprises bimetallic actuator, its install with heating element comparatively hot away from, for example between the cold lead (cold tail) of the element that has sheath.

In one group of embodiment, if (secondary) the mistake thermal actuator is set to its operation then can not be reset, promptly open its contact that for good and all keeps being associated this " secondary ".This provides additional security level.The locking mechanism that secondary therewith actuator is associated can be set, open with holding contact and/or actuator.Yet; The applicant observes; Owing to, also can after " elementary " actuator (promptly being installed in the actuator on the heating element) operated, operate even be positioned at secondary actuator at a distance through the remaining heat energy of well heater (for example via well heater or diffuser plate) diffusion.For anti-situation here takes place, in one group of embodiment, well heater or diffuser plate comprise the device in the direct heat path of interruption from heating element to secondary mistake thermal actuator.Interrupting device can comprise the hole that is formed in well heater or the diffuser plate, gap, groove, wall, plate washer etc., or comprises the additional caloic with well heater or diffuser plate thermo-contact.

For further improving the security of controller and equipment; In one group of embodiment; In case controller is arranged so that switch lever closure once more by the responsive actuator effect of overtemperature then before predetermined temperature conditions reaches; In a single day it is overheated promptly to detect, then sensing apparatus must be cooled to certain temperature before equipment can be operated once more.This has protected equipment and/or heating element can too fastly not to be heated after overheated detecting.Therefore permission equipment and/or heating element are cooled to safe temperature before can carrying out repetitive operation.

By contrast, in one group of embodiment, controller is arranged so that switch lever can be for example manually closed once more through " opening " button after the responsive actuator effect by boiling temperature.In other words, said controller is arranged so that said switch lever can be manually closed once more after by the effect of said boiling temperature sensing apparatus.This allows liquid formerly to reach boiling boiling once more soon afterwards.

In one group of embodiment, controller comprises the vertical installation component of general planar, and the for example switchgear and/or the elastic device of switch lever are installed on it.This self is novelty and creative; Therefore when when other aspect is seen; The utility model provides the electric controller that is used for liquid heating apparatus; The vertical installation component that comprises general planar, the downside of well heater of part pedestal that it is used for controller is installed to the liquid receiving chamber of forming device makes installation component substantially perpendicular to said pedestal setting.

With what recognize is the supporting that the vertical installation component of general planar provides the firm and rigidity that is used for controller.Typically, such controller is set to be installed on the downside of well heater or diffuser plate of liquid heat utensil.This plate is crooked when well heater is switched on, but vertically promptly will not receive the influence of moving along this direction perpendicular to the installation component of the general planar of well heater or diffuser plate setting.Therefore, controller will remain on identical position in whole heat cycles, and the parts that allow its parts particularly to move are accurately positioned.

In one group of embodiment, controller comprises one or more heat-sensitive actuating devices of the for example bimetallic actuator that is installed on the installation component.Typically, controller comprises three heat-sensitive actuating devices: two overheated or boiling dry combustion method sensor and boiling detecting sensors.Use installation component to locate the heat-sensitive actuating device and allow the heat-sensitive actuating device to be accurately positioned, for example upwards abut against well heater and/or the well heater or the diffuser plate location of liquid heating apparatus.For example, this allows bimetallic actuator to be positioned as to make therefore to make the only zonule of bimetallic actuator contact for example heating element by its only relevant portion of contact liq firing equipment.Because the heat-sensitive actuating device generally is accurately to be positioned at the most important parts on the controller with respect to liquid heating apparatus, so controller preferably includes it is attached to the device that the liquid heat utensil tightens adjacent heat-sensitive actuating device, for example rivet or screw.Therefore, even have some distortion at the well heater or the diffuser plate of liquid heating apparatus, the heat-sensitive actuating device also will remain on identical relative position.

In one group of embodiment, installation component is set to limit the travel distance of at least one part of heat-sensitive actuating device, for example limits through the retainer on the installation component.Preferably, the heat-sensitive actuating device is set to contact with installation component.For example, if be provided with heat-sensitive duplex metal actuator and it is installed on the installation component through its central tongue, then installation component also can limit the travel distance at the edge of bimetallic actuator.This will cause the travel distance of the opposite edges of bimetallic actuator to increase, because will trend towards making the plane slight inclination of actuator to the constraint of moving at an edge of actuator, and therefore amplify moving of opposite edges.As will recognize that the heat-sensitive actuating device acts directly in the device on the switch lever therein, and the moving not in the device that is amplified by the intermediate spring of instant heating sensitive actuator, this becomes important.

In one group of embodiment, controller comprises the movable contact member that is installed on the switch lever, and wherein switch lever is installed on the installation component pivotally.Switch lever and heat-sensitive actuating device (it acts on the switch lever) are installed on the installation component and for these two parts fixing relative position are provided.Therefore, though when liquid heating apparatus when operation installation component be moved, for example the distortion through heater plates is moved, switch lever does not also move with respect to the heat-sensitive actuating device.The stationary positioned that is independent of these parts that the heat of pedestal moves is useful; Because this allows the very little lost motion of design between them; This allows actuator as much as possible again mobilely is converted into moving of movable contact member; Wherein there is directly coupling between the two, like the situation in the preferred embodiment of the utility model at this.

Preferably, installation component comprises whole ground wire connections.The installation of the integral body that setting is processed by identical materials has been exempted them with the ground wire connections and has been set to the demand of separated components, and has therefore reduced the cost of controller.Preferably, the ground wire connections is using to be suitable for spending wireless connectors with 360 of annular.

As stated; Controller is suitable for using with the radio utensil especially goodly; Said electrical device comprises the connector part of 360 ° of types, the utensil connector part that can irrespectively partly engage with the corresponding dock connector that is provided by the power source base unit with the relative angle of two parts orientation.The wireless connector system can comprise that two or three electric terminals (for example fire line terminal, neutral line terminal and optional ground wire terminal) are connected to be used for basic power supply; StrixP72 for example; A large amount of terminal, for example the Strix P76 that perhaps comprise the electricity/data connection that is used to add.The example of suitable wireless connector system is described in the applicant's disclosed application WO 95/08204 and WO 01/28294.Especially, the utensil connector part can be the form that comprises the public connector part of one or more annular terminals, and the dock connector part can be the form that comprises the female connectors part of one or more corresponding annular depressions.

In typical wireless connector system, there are two groups of contacts that are coated with silver, one group of contact is arranged between the electric terminal of control module and utensil connector part, and another group contact is arranged in the dock connector part.As stated, one of purpose of the utility model is the electrical connection of more firmly setting up in the utensil, and realizes that a mode of this purpose is to reduce the quantity of contact through the movable contact that setting is installed on the switch lever, and this has practiced thrift material simultaneously.When controller was the part of wireless utensil, this purpose also was applicable to the contact in the dock connector part.Electric contact in the dock connector part can be installed on the flat spring, and said flat spring self is connected to the power supply that is used for base unit, as regular situation.Power supply provides through cable usually, and said cable leads to the dock connector part through the cable guide in the power source base unit.Yet the applicant has recognized that to reduce and is included in the quantity of the separated portions in the power source base unit and makes dock connector and benefit that service cable becomes one.Therefore; According to one group of preferred embodiment; Dock connector part becomes one with service cable, and the electric contact in the connector part is connected to the conductor in the service cable, and service cable integrally molded with the dock connector part be to hold the single parts of plastics of contact.In other words; Said cordless base connector and service cable become one; Said fixed contact member in the said cordless base connector is connected to the conductor in the said service cable, and said service cable and said cordless base connector are integrally molded for holding the single parts of plastics of said fixed contact member.

It is novelty and creative that this characteristic is considered to self; Irrelevant with controller; Therefore and when when other aspect is seen; The utility model provides the radio utensil; Said utensil comprises can be from the utensil unit that base unit separates, and said base unit is provided to the utensil unit through the dedicated radio link device with electric power when said utensil unit is placed on the base unit, and said connector is placed on the base unit and their the irrelevant type of relative angle orientation for allowing the utensil unit; Wireless connector comprises the connector part that has electric terminal in the utensil unit; It can engage with the corresponding connector part in the base unit to establish a connection to the electrical connection of the electric contact in it, and wherein dock connector part becomes one with service cable and the contact is connected to the conductor in the service cable, and service cable and dock connector part are integrally molded to be to hold the single parts of plastics of contact.

With what recognize is with service cable and the dock connector part or the Unitarily molded quantity that reduces needed molded operation during manufacture of major part of this connector at least, and through the protection that provides by molded plastic section branch make be electrically connected firmer.The assembling of power source base unit also can be simplified, and need not to be used for any independent securing member of service cable because the molded part of single plastics can be assembled to base unit.Unitarily molded part can fasten (snap) easily and be assembled to base unit in single number of assembling steps.Any other parts of dock connector part, covering etc. for example also can be for example cooperates (snap-fit) be attached to lead molded part through fastening.Covering can provide safety feature goes, prevents near (exposure) live wire part.

When the dock connector part is Unitarily molded with service cable; Can make electric contact be connected to the conductor in the service cable through the flat spring of routine; But this might make moulded parts complicated because moulded parts possibly must be formed with the inner space adapt to moving of contact when being installed on the flat spring in the contact.Therefore, further preferably make the contact have with service cable in the static state of conductor be connected.In other words, said fixed contact member have with said service cable in the static state of said conductor be connected.Such static state connects and can not interfere the operation of connector and have the feasible more endurable benefit that connects through the plastic mould encapsulation.For example cancelling, the movable part of flat spring can reduce quantity and economical with materials cost partly.Alternatively can use simple spade terminal or blade (" Fastum ") (" faston ") connector.Therefore yet these benefits can be exaggerated through cancelling any intermediate connector, and in one group of other preferred embodiment, the contact directly is connected with the interior conductor of service cable.In other words, said fixed contact member is directly connected to the said conductor in the said service cable.Therefore the integrality of the electrical connection in the base unit further is able to improve.

In one group of embodiment, firewire contact can comprise static the connection with neutral line contact, and the ground wire contact comprises flat spring.Preferably, firewire contact and neutral line contact are held by Unitarily molded part at least.In other words, said live wire and neutral line fixed contact member are held by said Unitarily molded part.Though the ground wire contact also can be in the Unitarily molded housing, in one group of embodiment, the ground wire contact is outstanding from Unitarily molded housing.Outstanding ground wire contact can and not make molded complicated operationization through the flat spring connection, because the periphery of housing can be obtained by the closure feature portion in the mould.

Will be appreciated that advantage discussed above does not rely on the attribute of controller or the attribute of utensil self in fact.Therefore the utility model extends to and is used for the dock connector part that the independently utensil in the radio utensil is partly supplied power; Connector part is separable; Make in electric terminal and the dock connector part of utensil connector part the connector part that is connected electrically in independently between the corresponding electric contact be put into a time-out and set up; And it is irrelevant with their relative angle orientation; Wherein dock connector part becomes one with service cable, and the electric contact in the connector part is connected to the conductor in the service cable, and service cable integrally molded with the dock connector part be to hold the single parts of plastics of contact.

Operation referring now to accompanying drawing description control device.In use; The top 2 of controller 1 is installed on the pedestal of the liquid heating apparatus of kettle for example, and steam bimetallic actuator 41 is arranged on place, end and two overheated

bimetallic actuators

33,37 of steam pipe and for example has the heating element thermal communication of the electrical heating elements of sheath under the chassis.Typically, the overheated bimetallic actuator 33 of hot side will be set to contact the heating element that has sheath, and the overheated bimetallic actuator 37 of neutral line side will be set to contact the diffuser plate between the cold lead of the heating element that has sheath.Overheated then firewire contact is at first opened if this causes heating element in normal running, will raise greater than the temperature on the diffuser plate between the cold lead because the temperature of the surface of element sheath raises.

Electricity dock connector part 4,102 is installed in the wireless connector pedestal 104, and an one of which example is described with reference to figures 10 to Figure 13 hereinafter.In operation, equipment is placed on the cordless base 104, makes the top 2 of controller 1 be placed on the top of electric dock connector part 4,102.Do not depress any of " opening " or " pass "

switch

48,50, firewire contact member 6 with neutral line contact member 8 through its

wire spring

11,13 separately via each

switch lever

10,12 by biased downward.The distal portion 62 of ejector return pin 56 is also by biased downward; Make in these place, end tab 64 outstanding centered cylinder parts 26 through controller 1; And side direction is towards the center-biased of controller 1, makes (see figure 7) below the side direction teat on the tab 64 at distal portion 62 places of ejector return pin 56 is coupled to the lip 66 of live wire switch lever 10.

Therefore, when the top 2 of controller 1 was placed on the top of electric dock connector part 4,102, the tab 64 on the ejector return pin 56 contacted with the plastic mould of dock connector part 4,102, thereby distal portion 62 and live wire switch lever 10 are upwards risen.Neutral line contact member 8 contacts with dock connector part 4,102 interior fixedly neutral line contacts 114; But leave the fixedly firewire contact 112 in (clear) dock connector part 4,102 because firewire contact member 6 is raised; Circuit is also imperfect, and therefore the interior heating element of equipment is not energized.And ground wire connector ring 26 contacts with dock connector part 4,102 interior ground wire contacts 116.

In order to make the heating element energising in the equipment, will open button 48 and be pressed into.Open the wedge projection 68 (seeing Fig. 5 and Fig. 7) on the distal portion 70 backup ejector return pins 56 of button, with the central side of its distal portion 62 slave controllers 1 to removing and lip 66 from live wire switch lever 10 leaves.This has discharged live wire switch lever 10, and said live wire switch lever 10 is moved down through the bias force of wire spring 11 then, makes removable firewire contact member 6 contact with dock connector part 4,102 interior fixedly firewire contacts 112.Therefore this makes circuit complete and make the heating element energising.Though not shown, " opening " and " pass " button can be by interlocking, for example through the for example link mechanism interlocking of pivot rods.This will cause when a button is pressed into another button by by going out.

In case the heating element energising, then the liquid in the equipment is heated to boiling, if but owing to any reason will stop heating, also can depress " pass " button 50." pass " button is depressed the latch 54 that causes on the live wire switch lever to be moved down through the wedge-shaped part on " pass " button 50 52.This 114 rises removable neutral line contact member 8 to remove from fixing neutral line contact, and has broken off circuit, therefore heating element is cut off the power supply.Otherwise heating and continuous to boiling, this has produced steam in equipment.The pressure increase that the volume increase of steam causes impels steam to get in the steam pipe and impacts downwards on the steam bimetallic actuator 41.The snap-action temperature of bimetallic actuator 41 need not be arranged on 100 ℃ and locate, i.e. boiling place, but can be lower, for example 75 ℃,, exist in the steam indication equipment to be in boiling because this only is to have steam.This has realized that reliable boiling detects.When 41 sudden changes of steam bimetallic actuator, because the vertical installing plate 18 of the pedestal of bimetallic actuator 41 43 contacts takes place so all of bimetallic actuator 41 move in hoop part 44.Steam bimetallic actuator 41 pushes away downwards on the hook-type tab 45 on the live wire switch lever 10, and live wire switch lever 10 is pivoted, and this leaves the fixedly firewire contact 112 in the dock connector part 4,102 with removable firewire contact member 6 rises.This has broken off circuit and has made the heating element outage.If hope liquid boiling soon after the heating element outage, then " opening " button 48 can be pressed, and this is through the 53 rotation steam override control bars 55 of the recess on the arm of " opening " button 48.Steam override control bar 55 pushes away steam bimetallic actuator 41 from the hook-type tab 45 on the live wire switch lever 10, and therefore allows firewire contact 6 to rebulid, for heating element is switched on once more.

Under the overheated situation of heating element; If for example opening of device and in container no any water; Therefore then overheated bimetallic actuator 33 sudden changes are removed removable firewire contact member 6 to act on the live wire switch lever 10 from the fixedly firewire contact 112 in the connector base part 4,102.Live wire bimetallic actuator 33 will at first suddenly change, because it contacts with heating element, this is opposite with the neutral line bimetallic actuator 37 that is positioned between the cold lead of the heating element that has sheath.If for a certain reason; The overheated bimetallic actuator 33 of live wire does not suddenly change; Then neutral line bimetallic actuator 37 will suddenly change subsequently; Neutral line contact bar 12 is risen, and therefore removable neutral line contact 8 is removed from the fixedly neutral line contact 114 in the connector base part 4,102, and heating element is cut off the power supply.

For steam bimetallic actuator 41; When overheated

bimetallic actuator

33,37 sudden changes of live wire and the neutral line; Because the vertical installing plate 18 of their

pedestal

35,39 contacts respectively binds round in the

part

36,40 so all of

bimetallic actuator

33,37 move all to occur in.Equally, the heating element outage, this prevents any damage for heating element and/or equipment in the case.When live wire switch lever 10 is risen by overheated bimetallic actuator 33, moved below live wire switch lever 10 by the ejector return pin 56 of its wire spring 60 towards the center-biased of controller 1, prevent that removable firewire contact 6 from setting up circuit once more.Can be used for discharging live wire switch lever 10 though " open " button 48, until 33 coolings of the overheated bimetallic actuator of live wire and reset, bar just moves down back to set up circuit once more.This operation with steam bimetallic actuator 41 is different, and this steam bimetallic actuator 41 can use steam override control bar 55 to reset.Because safety reasons is not provided with override control mechanism for overheated

bimetallic actuator

33,37.

With what recognize be, control device described here can use in many dissimilar liquid heating apparatus, includes kettle and water ebullator, hot water dispenser, beverage making machine and the vapour iron of rope and wireless type.
