Alternatively, but the inductance heating material can be arranged on the top of kettle, for example can place the heat dish of teapot 3 or other container on it.
The power grade of inductive heater can be controlled according to the tea temperature in the detected container 6.Alternatively, when the contents in the container reach desired temperature, but the inductance heating material can be selected to and has Curie temperature.In the case, heating power self-regulation.
Reduce the friction teapot
Inductance coil 22 can be used as electromagnet, and teapot 3 can comprise diamagnetism or conductive material, makes electromagnet apply power upwards on teapot 3, so that reduce the effective weight of teapot 3, and therefore reduce the friction that relative kettle 1 produces.Advantageously, this can reduce the frictional force between teapot 3 and the kettle 1, allows teapot 3 to rotate more freely with respect to kettle 1.If for coil provides enough energy, teapot 3 is levitated from kettle 1, this depends on the weight of teapot 3; This can provide the vision how much tea is arranged in teapot indication.Can be provided for stablizing the device of teapot 3; Stabilising arrangement can be magnetic, electro permanent magnetic or mechanical.This have or do not provide the stabilising arrangement of active force upwards to can be used for making teapot 3 relative kettles 1 to be arranged on the center.Active force upwards can be provided by the electromagnet as inductance coil not.
Additional heating characteristics
In above-mentioned arbitrary embodiment, teapot is direct-fired by its oneself heater 22, and heat is to conduct to teapot 3 from kettle 1 by the mode of thermal bridge.Thermal bridge can with water 4 thermo-contacts in the heater 22 of kettle 1 and/or the kettle 1.Therefore, replace depending on hot gas or steam convection current and make teapot 3 insulations, by thermal bridge conduction heat.
Kettle 1 and/or teapot 3 can be insulated so that realize the thermal balance of expection when muff heater (many heaters) is powered.For example, kettle 1 can be heat insulation so that hotly mainly from teapot 3, release, or vice versa.Like this, single heater 22 can make the temperature that water 4 and tea remain on to be needed.In a specific example, water 4 be by with the mode of the heater 22 of teapot 3 thermo-contacts, utilize heat insulation and/or being provided with of heater of kettle 1 or teapot 3 to be incubated, for example as shown in Figure 6.
Teapot can comprise the heat dissipation plate in the basal part of container 6, is used to guarantee the even heating of tea and avoids tea smell is produced the local boiling of infringement.
Add thermal control
In the embodiment of above-mentioned arbitrary non-self-regulation heating, the power output of heater (many heaters) can be controlled according to the water of heating or the water level of tea.Water level can detect by the level sensor of describing among for example application GB0709164.8 before us and the GB0711752.6, and its content combines at this as a reference.Especially, the power output that is used for heat insulation function can be controlled according to detected water level.
After heating mode finishes, for example in response to the detection of seething with excitement, kettle 1 enterable insulation pattern.Alternatively, insulation pattern can be independent of heating mode conversion.Heating under the insulation pattern can be regulated by the power grade of control heater, perhaps by utilizing the load cycle pulsation ground switch heater that changes to realize the expection average rank that heats.Periodically, for example at all after dates of predetermined number, can enter heating mode once more and make water get back to fluidized state and then enter the insulation pattern once more.
Provide among the embodiment of muff heater for teapot 3 at those, when teapot 3 when kettle is removed, muff heater can cut off, or reduces power grade.This can pass through on the lid 12 or contact-making switch is on every side realized, perhaps realizes by above-mentioned other method.
Can be provided with controller on kettle 1, this controller detects when water 4 reaches simmer (simmer) and/or boiling fully; Can enter the insulation pattern then, heating is stopped together.Under the insulation pattern, counter can be set make periodically, for example entered heating mode in per 2 minutes, so that make water reach boiling point or inferior boiling point.This controller monitors the stirring of water, and this stirs expression simmer state.Preferably, in case enter the insulation pattern, when detecting simmer, controller continues to monitor the stirring of water, and reduces or stop the insulation heating.
Under this mode, vapor sensor no longer is essential; Because can avoid the condensation of controller, and there is not the cost of vapor sensor, so this is favourable.When also can provide thermostat to detect water cooling to being lower than minimum threshold, thereby need enter the insulation pattern.Yet the heat input during the preferably insulation pattern changes, and with the heat radiation of coupling water 4, therefore can avoid the circulation of thermostat.
In one embodiment, monitor stirring by level switch, this level switch is sensed because water becomes water level rapid fluctuations less when occurring stirring.In another embodiment, the acoustic sensor supervision stirring of the sound characteristic when reaching boiling point, for example caused reduction that adds thermal noise of the minimizing of the collision of the steam steam bubble in the water when water reaches boiling point by detecting water.
As shown in figure 11, level sensor example is the distance measuring equipment 23 around being positioned at kettle 1 top or top.This equipment can be laser or ultrasonic distance measurement device.Equipment 23 accurately measures the fluctuation at the absolute distance place of the water surface, and when the controller detection fluctuates above predetermined water level.Predetermined water level changes based on the water yield in the container, also can determine by this equipment according to the absolute distance to the water surface.
As shown in figure 11, distance measuring equipment 23 can be located substantially on the central vertical shaft of kettle 1, and the accuracy that makes water level accurately measure does not rely on vertical kettle.Alternatively, can a plurality of distance measuring equipments be set, so that the angle of compensation kettle 1 at diverse location.When kettle 1 suitably remained on an angle, distance measuring equipment (a plurality of distance measuring equipment) can be used for accurately measuring the water level during tap is filled with water.Selectively, distance measuring equipment can be positioned at the cistern outside of kettle, and can be directed to the water surface by window.
Another example of level sensor is included in around the kettle 1, in cistern or the condenser type level sensor array of location, the outside.This array also can be used for measuring water level when kettle 1 is in certain angle.
