Description

Controller
Technical field
The present invention relates to the controller for controlling liquid heating apparatus, such as, for turning off equipment or overheated for preventing when the water is boiling, and relating to the assembly and utensil that comprise this controller.
Background technology
The traditional liquid firing equipment of such as insulating pot or hot-water cylinder is equipped with boiling controller, and during this boiling controller liquid boiling in a reservoir, operation is to be cut to the power supply of the heater of container, no longer continues to make boiling.Similarly, the heat controller excessively of cutting off the electricity supply when heater exceedes safe operating temperature can be arranged on.
Usually, this controller adopts copper alloy leaf spring as movable contact, and to set up or to disconnect power circuit, wherein leaf spring transmits electric current as a part for circuit.Typically, leaf spring is acted on via promotion rod by heat-sensitive duplex metal actuator, operates when this heat-sensitive duplex metal actuator liquid boiling in a reservoir or overheated heater.Usually, these controllers rely on cantilevered leaf spring, and it is by free bend during actuator effect, to move away contact.
When cordless liquid firing equipment engages with dock connector, supply of electric power is to cordless liquid firing equipment.Another group contact is arranged in dock connector, to make the open circuit when equipment and base-separation.
Summary of the invention
The object of this invention is to provide the controller for the improvement of liquid heating apparatus and controller assemblies.
When viewed from first aspect, the invention provides the controller assemblies for cordless liquid firing equipment, this controller assemblies comprises for being installed to liquid heating apparatus to control the controller to the supply of electric power of this liquid heating apparatus, be suitable for supplying power to the cordless base connector of controller and the switching device for setting up or disconnect the circuit for supplying power to liquid heating apparatus when engaging with controller, this switching device comprises and is arranged on the stationary electrical contacts on cordless base connector and the removable electric contact for engaging with stationary electrical contacts, wherein removable electric contact is arranged on the free end of resilient member, this resilient member locates the fixing movement that also can bend to realize electric contact on one point, the movement of another some place resilient member between fixing point and free end suffers restraints, to control by the movement of the bending electric contact caused of resilient member.
The controller extended in this respect for cordless liquid firing equipment of the present invention, this controller comprises the switching device for setting up or disconnect the circuit for supplying power to liquid heating apparatus, this switching device comprises the removable electric contact of the free end being arranged on resilient member, this resilient member locates the fixing movement that also can bend to realize electric contact on one point, the movement of another some place resilient member between fixing point and free end suffers restraints, to control by the movement of the bending electric contact caused of resilient member.
This controller can be configured such that removable electric contact engages with the fixed contact be arranged on inside controller, but preferably, as according to a first aspect of the invention, removable electric contact engages with the fixed contact provided by cordless base connector.
Can understand, compared to adopting the leaf spring of free bend to carry out current collector with the device (such as cantilever arrangement) of the circuit set up or in breaking controller, resilient member suffers restraints can limit the movement of contact.The operation of this switching device can comparatively accurately and can predict.Such as, controlling a contact may be important relative to another movement, thus guarantees on the one hand to obtain good electrical contact, obtains the controlled detachment of contact on the other hand.Especially, when movable contact move with (being such as arranged on cordless base connector) fixed contact electrical contact or not with this fixed contact electrical contact time, then can limit space available around (such as specified by cordless base connector) fixed contact.
In addition less electric current, when foundation or disconnection are when being arranged on the circuit at the fixed contact place on cordless base connector, considerable benefit can be obtained, because may be needed on the whole to transmit contact pair.In the device of routine, between two wireless connector parts (dock connector and the connector provided by controller), there is contact, and in the controller for Switching Power Supply (such as to prevent the elements overheating), also have another group contact.Instead, switching device described herein can perform switch and leads to the power supply of equipment and be installed to the dual-use function of separable electrical connection of the necessity between the controller of liquid heating apparatus and cordless base connector.Therefore, preferably, controller assemblies forms by for the single switch device set up or disconnect the circuit supplying power to liquid heating apparatus.This is favourable, because electric contact typically needs silver-colored contact surface, and this significantly can increase the ratio of the manufacturing cost of controller.The cancellation of one group of contact reduce the moving-member in controller quantity in be also useful, which improve reliability.In addition, because the resilient member in controller of the present invention can provide necessary contact, therefore unnecessaryly in cordless base connector, arrange resiliently biased contact, this makes it more durable and allows more cost-effective manufacture.
Be appreciated that resilient member is set to be bent by external force, to realize the movement of the electric contact being installed to it.Switching device preferably includes the actuator of such as removable promotion component, and another place be tied a little that this actuator is set to leaving resilient member acts in resilient member.Actuator can act in resilient member with a little isolated any some place that be tied.In one group of embodiment, the some place of actuator between the fixing point of resilient member and it be tied a little acts in resilient member.Resilient member is not freely bending from its fixing point in cantilevered fashion, but only can bend within compulsory affined scope.Therefore, the degree carrying the movement of the free end of electric contact depends on the power being tied a little and being applied by actuator.Except the elastic response of resilient member, have also obtained independently mobile control.This can be formed with the device that electric contact is installed to bimetal part (bimetallic actuator of such as wriggling) and contrast, and this bimetal part is by itself deflection during heating.Although resilient member can be acted on directly or indirectly by bimetallic actuator (will discuss in more detail below), itself is not bimetallic actuator.
Switching device can be shared between controller and cordless base connector.But preferably, at least removable electric contact is associated with controller, be arranged in cordless liquid firing equipment in therefore using.When controller engages with cordless base connector, preferably, movable contact automatically engages with fixed contact, such as, be placed on once equipment on the base unit carrying cordless base connector and just supply electric power.Therefore, resilient member can be set to provide the resilience impelling movable contact to engage with fixed contact to be biased.The bending of resilient member must overcome this being biased, to be removed from fixed contact by electric contact.In one group of embodiment, can fastening device be provided, so that resilient member is maintained in curved configuration, disconnect, until equipment is manually connected with maintained switch device.Fastening device can directly act in resilient member, and so that it is remained in curved configuration, wherein removable electric contact is separated with stationary electrical contacts.Or fastening device can interact with actuator (when providing), it is made to be in the position of curved configuration it to be remained on to act in resilient member.
As mentioned above, preferably, the bending of resilient member causes removable electric contact to be removed from stationary electrical contacts, thus disconnects the circuit for supplying power to liquid heating apparatus.Depend on the orientation of the fixed contact in controller assemblies, removable electric contact can along any direction---such as vertically or flatly---, and engage with fixed contact, therefore resilient member can be set to along the mobile movable contact of in these specific directions.In one group of embodiment, removable electric contact can be arranged on the free end of the resilient member roughly extended in the plane of controller assemblies.The bending movement that then can realize along the direction roughly outside the plane of controller assemblies of resilient member.But this device may need to provide head room in controller assemblies, this head room can hinder the vertical expanded range of controller assemblies to minimize.
In other group embodiment, removable electric contact can be arranged on the free end extending the plane of controller assemblies of resilient member.The bending movement that then can realize along the direction roughly in the plane of controller assemblies of resilient member, being i.e. displaced sideways of electric contact.In these embodiments, when controller engages with cordless base connector, the slip joint (action that is namely close to (side-swipe action)) of contact can be obtained.The vertical height minimizing controller assemblies can be helped relative to the sideways scheme of fixed contact (sideways approach), because the free end installing the resilient member of movable contact can extend, with overlapping with the degree of depth of cordless base connector.In these embodiments, switching device can comprise resilient member, its have roughly laterally extend in controller assemblies in fixing point and the part between being tied a little.The part of resilient member between the free end be tied a little and install removable electric contact can be parallel to cordless base connector (such as roughly outside the plane of controller assemblies) and extend.Preferably, resilient member can with the angle folding of (but being preferably about 90 °) between 0 ° and 180 ° between the two parts extended to be tied, such as, be the component of roughly J-shaped, L shape or T-shaped.This kink in resilient member can provide affined point easily.
There is multiple different mode can retrain the movement of resilient member.The mobile bound meaning refers to and reduces or remove at least one degree of freedom.In an example, possible resilient member moves along the translation in any direction and suffers restraints, but leave the freedom of pivotable, for example, fixing pivotal point can pass resilient member (the kink place such as when being provided with a kink then in component).But be that the free end of resilient member is then forced to along bow-shaped route by the mobile problem being constrained to only pivotable, this may make the accurate joint being comparatively difficult to guarantee movable contact and fixed contact.In one group of preferred embodiment, only retrain the translational motion of resilient member along the direction (such as in the z-direction) outside its plane.Which has limited the bending motion of component, but guarantee it can in its plane backward/forward slip and around a pivotable that is tied.Slide and free end that this combination of pivotable can help to carry removable electric contact roughly linearly but not move along bow-shaped route.
Resilient member can be made to bend and be removed from fixed contact by electric contact when being subject to acting on more than a bit.Especially, applicant has realized that the somewhere between two arms of resilient member is arranged and is tied a little, and another arm of fixed component simultaneously, means and can realize moving from the either side be tied a little.Therefore, two actuators can be set to act on independently in resilient member from the not homonymy be tied a little.Resilient member can comprise the component with three arms, such as T-shaped component.First arm can comprise fixing point, and the second arm can be fix, semifixed or freely.3rd arm can comprise the free end carrying removable electric contact.Be tied and be a little arranged between these three arms.When making the first arm or the second arm bends, preferably when by corresponding actuator effect, this causes the controlled movement (as what a little specified by being tied between three arms) of the electric contact carried by the 3rd arm.A four or more arm can be adopted, although add complexity for switching device.
In one group of embodiment, resilient member comprises first arm with the removable electric contact being arranged on free end and two other arms, the point of contact place be tied o'clock between three arms.Second arm is set to the first actuator effect by such as responsive to temperature actuator, to bend and to be removed from fixed contact by electric contact.3rd arm is set to by the second actuator effect of such as crossing thermal actuator, to bend and to be removed from fixed contact by electric contact.First actuator and the second actuator preferably act on the second arm and the 3rd arm along relative direction respectively, to cause the first arm along the movement (that is, being removed from fixed contact by electric contact) of equidirectional.This embodiment makes to provide two independently protection class easily by single resilient member.In addition, the first actuator and the second actuator can contribute to effective use in the space in controller assemblies along the operation of relative direction, and help to maintain package be compact while maximum functionality.
In order to the initial construction making resilient member turn back to it after bending, it preferably includes spring member.Resilient member can be made up of suitable plastic material (such as around the elastomer that electric current conveyer line is molded), but preferably, resilient member comprises electric conducting material, can transmit electric current to removable electric contact to make itself.In one group of embodiment, resilient member comprises metal material, preferably includes the metal material providing relatively high conductivity of such as copper or copper alloy.Resilient member preferably includes leaf spring member.The leaf spring member of conduction facilitates especially and economic mode electric current being supplied to removable electric contact, also provides bending and required for current collector resilience simultaneously.
The intrinsic resilience of resilient member can be relied on to provide contact between removable electric contact and stationary electrical contacts.But applicant recognizes, guarantee between electric contact, have enough contacts to be important, particularly set up or live wire electrode (i.e. the electric current of Switching Power Supply) of open circuit time.Therefore in one group of embodiment, preferably controller assemblies or controller comprise such device further, this device is arranged relative to fixed contact to be bearing in resilient member, its free end is resiliently biased, engages to be moved to by electric contact with stationary electrical contacts.This " specified (rating) " device to guarantee when electric contact engages resilient member at least by stress application slightly, and therefore component applies certain contact.The position of the position relative to fixed contact of rated device can be chosen as the deflection providing expectation at free end, thus is provided as the contact of the expectation of the result that resilience is biased.
In at least some embodiments, " specified " device a little can provide by being tied or engage with being tied.Particularly when resilient member bends between the two parts extended to be tied, the constraint being applied to this kink can be set to the part Shi Hanzhang of the carrying movable contact to resilient member, and to make, its free end is resiliently biased to be engaged with stationary electrical contacts to be moved to by electric contact.The bending stress that can discharge resilient member of the resilient member that electric contact is removed from stationary electrical contacts.But in another group embodiment, " specified " device is a little arranged discretely with being tied.It is independent that this will maintain power in resilient member.Especially, in order to obtain benefit completely from " specified " device, it is important for making it arrange relative to the stationary electrical contacts be arranged on cordless base connector.Assuming that the parts of controller assemblies are removable relative to cordless base connector, and the controller part of assembly can depart from from cordless base connector, and " specified " device preferably also can be arranged on cordless base connector." specified " device can be in the fixed position relative to stationary electrical contacts on cordless base connector.
In use, when controller to engage with cordless base connector and engage contacts time, it is complete that resilient member can be used in the circuit supplying power to liquid heating apparatus.Resilient member can be provided with the terminals for being electrically connected to liquid heating apparatus.The single switch device of described type can be set, and such as only for the hot side of Switching Power Supply, such as be connected to the neutral line and the terminals (when being provided with) of ground wire other electric contact differently (such as rigid line) be connected.But in one group of embodiment, controller comprises at least two this switching devices, such as, for switch live wire electrode and neutral line pole.But, as mentioned above, preferably, a switching device is only set to set up or to disconnect the circuit (i.e. main switchgear) supplying power to liquid heating apparatus.Although the contact in main switchgear can have silver-colored contact surface for this purpose, the contact in other switching device is to not being used for any electric current of switch and can lack silver-plated or not silver-plated due to it.
When arranging two (or more) switching devices, identical resilient member can be used for installing corresponding contact to (such as live wire and the neutral line).But, for each contact is to the resilient member arranging separation in one group of embodiment.This makes corresponding switching device be easier to independent operation, such as, by independently actuator effect.Applicant has realized that the increase of the quantity of switching device may increase the space of the moving-member for it required for controller assemblies.But, expect to make controller assemblies as far as possible compactly, to reduce the space that it occupies in liquid heating apparatus, together with the material be associated and the carbon footprint (carbon footprint) etc. for transporting.In one group of preferred embodiment, switching device comprises two resilient member, each resilient member has installed the removable electric contact for engaging with corresponding stationary electrical contacts, resilient member arranges roughly abreast and extends along relative direction from their points fixing accordingly, and bending its electric contact that causes of a resilient member is moved along the direction contrary with the movement of the electric contact caused by the bending of another resilient member.
This self is considered to novel and creative at it, therefore when viewed from second aspect, the invention provides the controller assemblies for cordless liquid firing equipment, this controller assemblies comprises for being installed to liquid heating apparatus to control the controller to the supply of electric power of this liquid heating apparatus, be suitable for supplying power to the cordless base connector of controller and the switching device for setting up or disconnect the circuit for supplying power to liquid heating apparatus when engaging with controller, this switching device comprises and is arranged on the first stationary electrical contacts on cordless base connector and the second stationary electrical contacts, and for the first corresponding removable electric contact of engaging to stationary electrical contacts and the second removable electric contact, each in first removable electric contact and the second removable electric contact is arranged on corresponding first resilient member of the movement that can bend to realize electric contact and the free end of the second resilient member, wherein the first resilient member and the second resilient member arrange roughly abreast and extend along relative direction from corresponding fixing point, move along the direction contrary with the movement of the second electric contact caused by the bending of the second resilient member to make bending first electric contact that causes of the first resilient member.
The controller also extended in this respect for being installed to liquid heating apparatus of the present invention, this controller comprises the switching device for setting up or disconnect the circuit for supplying power to liquid heating apparatus, this switching device comprises the first removable electric contact and the second removable electric contact, each in first removable electric contact and the second removable electric contact is arranged on corresponding first resilient member of the movement that can bend to realize electric contact and the free end of the second resilient member, wherein the first resilient member and the second resilient member arrange roughly abreast and extend along relative direction from corresponding fixing point, move along the direction contrary with the movement of the second electric contact caused by the bending of the second resilient member to make bending first electric contact that causes of the first resilient member.This controller can be configured such that removable electric contact engages with the first corresponding stationary electrical contacts and the second stationary electrical contacts.Fixed contact can be arranged on inside controller, but preferably, as according to a first aspect of the invention, they are provided by cordless base connector.
Can understand, comprising in the switching device right along (at least) two contacts of relative direction cut-off/close by corresponding resilient member, controller or controller assemblies can potentially through being configured such that contrary movement overlap in same level makes compacter.This benefit can be improved in all embodiments as described above, and wherein the free end of the removable electric contact of the installation of each resilient member extends outside the plane of controller assemblies.Preferably, the first resilient member and the second resilient member are arranged abreast, to bend and to realize along the rightabout movement roughly in the plane of controller assemblies, be i.e. relative being displaced sideways of electric contact.Free end due to the installation movable contact of resilient member can extend to overlapping with the cordless base connector degree of depth, but do not interfere the movement between them, therefore this dual vertical height that can minimize controller assemblies relative to the sideways scheme of fixed contact.Preferably, resilient member between their accordingly fixing point and free ends with can between 0 ° and 180 ° the angle folding of (but being preferably about 90 °), such as, they are the component of roughly J-shaped, L shape or T-shaped.Compact switching device may be specially adapted to the controller for such liquid heating apparatus, and this liquid heating apparatus comprises the heater of the relative low-power of such as 1.5kW and has the little base region holding controller.
As according to a first aspect of the invention, although resilient member can be freely bending from their fixing point, but preferably, their another place of movement between fixing point and free end suffers restraints, to provide the control of the movement caused by the bending of resilient member to electric contact.Any one of further feature as described above equivalently can be applied to this second aspect of the present invention.To the characteristic sum embodiment being applied to any one of aforementioned aspect of the present invention be described now.
Removable electric contact preferably includes the material of the good electric conductor of such as copper.In one group of embodiment, movable contact comprises silver coating or tip.Selection silver is the conductivity of Yin Qigao, which reduce the trend that contact surface is degenerated by being oxidized, but preferably silver only provides as coating or at tip, be namely provided in the position setting up physical contact with fixed contact, maximize the validity of silver with the cost reducing contact simultaneously.Preferably similar, the contact surface of fixed contact comprises silver.But applicant has been found that in opposition side when being copper, only on side, (namely on movable contact or fixed contact) uses silver to provide enough performances.This is because the plasma generated during the starting the arc when contact disconnects causes the silver-colored melting on a contact, thus silver layer is caused to be deposited on relative contact.
In one group of embodiment of two movable contacts that the pole be such as separated for switch is provided, possible in them only one comprise silver coating or tip, that being preferably used for switch live wire (main (primary)) pole comprises silver coating or tip.Controller can be advantageously arranged to and make during normal use, and the electric contact with silver-colored contact surface is first preferentially set up or disconnected contact.This maximises the benefit of a small amount of silver, allows other contacts to without silver or with less silver simultaneously.
In one group of embodiment, switching device comprises resilient member, and this resilient member is set to the movable contact mounted thereto fixed contact from its correspondence be removed when liquid heating apparatus reaches predetermined temperature.When providing multiple electric contact (such as live wire and the neutral line), so this preferably disconnects the circuit of the live wire electrode for power supply.Can be that liquid in equipment reaches predetermined temperature (such as seething with excitement) or electrical heating elements reaches predetermined temperature (such as instruction boiling or overheated).In one group of embodiment, controller comprises the responsive to temperature actuator being set to the such as bimetallic actuator acted in resilient member.Actuator can act in resilient member directly or indirectly.Actuator can comprise boiling transducer (such as vapor sensor) or overheat sensor.Controller may further include the device for the movement of actuator being passed to resilient member, such as or bar excellent by actuator effect promotion thereon.The bimetallic actuator of quick-action (snap-action) can be used for guaranteeing the quick response at preferred temperature.
When the responsive to temperature actuator of such as quick-action (snap-acting) bimetallic actuator to act in resilient member with separated contacts, then can utilize the characteristic of lever.Such as, make actuator from the point that is tied (or fixing point by arranging, when according to second aspect be not must arrange be tied some) distance that compares the distance of movable contact nearer acts in resilient member, the movement of actuator is amplified by the bending of resilient member.Also the work of lever can be utilized to be exaggerated in order to allow the relatively little power imposed by actuator, to disconnect movable contact against resilience bias force, to make it possible to use relatively high resilience to be biased to guarantee high contact.This generates safer controller, because the relatively little travel distance of the actuator of such as quick-action bimetallic actuator can be enlarged into the larger travel distance of movable contact, guarantee there are enough separation to meet safety standard from fixed contact.
In one group of preferred embodiment, responsive to temperature actuator is installed on the controller, so that when controller is installed to liquid heating apparatus, responsive to temperature actuator and liquid heating apparatus set up thermo-contact and responsive to temperature to liquid heating apparatus, responsive to temperature actuator is set to (directly or indirectly) and acts in resilient member, so that when liquid heating apparatus reaches predetermined temperature, movable contact is removed from fixed contact by resilient member.Responsive to temperature actuator is preferably quick-action bimetallic actuator.
Preferably, responsive to temperature actuator is arranged on the outside of controller.Controller can comprise more than one actuator, such as a sensing boiling, and a sensing is overheated.In one group of embodiment, controller comprises the responsive to temperature actuator of the boiling of the liquid be set in tracer liquid firing equipment, such as steam cock (it can comprise bimetallic actuator), responsive to temperature actuator is set to act in resilient member to be separated movable contact and fixed contact.In another group (non-exclusive) embodiment, controller comprises the overheated responsive to temperature actuator being set to tracer liquid firing equipment, such as its can comprise be arranged on electrical heating elements or against electrical heating elements install bimetallic actuator or thermo-fuse, responsive to temperature actuator is set to (directly or indirectly) and acts in resilient member to be separated movable contact and fixed contact.Act in the embodiment that identical resilient member (such as acts on the different arm of resilient member) as described above at two different actuators, an actuator can comprise the bimetallic actuator being set to tracer liquid temperature, and another actuator can comprise the thermo-fuse being set to be detected heat condition.Multiple actuator can be used to provide the additional level of the backup protection for safety.
