- Figures 7B to 7H illustrate the data displayed on the kettle during the example of Figure 7A; and Figure 8 is a plot of temperature versus time illustrating operation of the kettle of Figure 1.
- Heating vessels are in common use and are often used to bring liquid contents to the boil or some other desired temperature.
- the rate of heating depends on factors such as the initial temperature of the liquid contents and the volume of liquid present in the vessel relative to the power available to heat.
- the arrangements described herein include a data display that provides an estimate of the time required for the contents of the heating vessel to reach a specified temperature, such as the boiling point of water.
- the described embodiment relates to a kettle, but it will be appreciated that similar arrangements may be used in other heating vessels.
- FIG. 1 shows a cross-sectional view of an electric kettle 10.
- the electric kettle has a heating chamber 12, which holds the water to be boiled.
- the water may be poured into the heating chamber 12 of the kettle through the pouring spout 14.
- the base wall of the heating chamber 12 is defined by a contact plate 16.
- Water stored in the heating chamber 12 is in direct contact with one side of the contact plate 16.
- the contact plate 16 is formed from stainless steel. Other materials which are suitable for contacting water and are resistant to high temperatures and oxidation may be used.
- the contact plate 16 forms part of a heater assembly 18.
- the heater assembly is generally located underneath the internal chamber 12 on the opposite side of the contact plate to the heating chamber 12.
- One embodiment of the heater assembly 18 is shown in greater detail in Figures 2 to 4.
- the heater assembly 18 is powered by a power source (not shown) which is external to the kettle 10.
- the power may be transmitted to the heater assembly 18 using known techniques, for instance through a plug-in electrical lead.
- the heat used to boil the water is generated by a heating element 20, which terminates in cold tails carrying electrical connections 22.
- the heating element 20 is powered by electricity.
- the heating element 22 shown is a resistance element. Other types of heating elements may be used.
- the heating element 20 is bonded to a heat distribution plate 24.
- the bonding achieves a good thermal coupling between the heating element 20 and the heat distribution plate 24 so that heat generated by the heating element 20 is rapidly and efficiently transferred to the heat distribution plate 24.
- Many known bonding techniques are suitable including induction welding, flame or oven welding and impact welding.
- the heating element 20 may be mounted to the heat distribution plate 24 using other known techniques, such as mechanical fasteners.
- the heat distribution plate 24 is induction brazed to the contact plate 16 so there is a good thermal coupling between the heat distribution plate 24 and the contact plate 16.
- Many other known bonding techniques are suitable, including the bonding techniques mentioned above.
- the heat distribution plate 24 may be mounted to the contact plate 16 using other known techniques, such as mechanical fasteners.
- the heat distribution plate 24 is formed from aluminium, which is a good thermal conductor, and is of sufficient thickness so that heat is evenly distributed over the contact plate 16.
- Alternative materials for the heat distribution plate 24 include other metals and metal alloys.
- the heat distribution plate 24 is generally thicker than the contact plate and formed from a material which is a better thermal conductor than the contact plate 16.
- the heat distribution plate 24 defines a void 26 in the vicinity of the cold tails 22.
- the void 26 forms a thermally insulating zone. This is because heat which is transmitted from the heating element 20 to the heat distribution plate 24 is not as readily transmitted across the void 26.
- the region of the contact plate 16 located in the void 26 does not conduct significant amounts of heat when compared to the aluminium heat distribution plate because the contact plate 16 is thin and formed from stainless steel, which is not as good a thermal conductor.
- Mounted in the void 26 is an electronic temperature sensor 28.
- the void 26 provides a thermally insulating zone around the electronic temperature sensor 28. Heat from the heat distribution plate 24 is not readily transmitted to the electronic temperature sensor 28.
- the electronic temperature sensor 28 is thermally insulated and is not undesirably influenced by the temperature of the heating element 20 and heat distribution plate 24.
- the thermally insulating zone and the temperature sensor 28 are located between the cold tails 22 of the heating element 20.
- the cold tails do not generate significant amounts of heat, so the electronic temperature sensor 28 is further insulated from the heat generated by the heating element 20.
- the void 26 may be filled, either partially or wholly, with an insulating material, such as silicone or rubber.
- the temperature sensor 28 is mounted in close proximity to the contact plate 16.
- the temperature sensor 28 may be touching the contact plate 16. This improves the thermal coupling between the electronic temperature sensor 28 and the contact plate 16.
- the thermal coupling may be further improved using known techniques, such as applying a heat transfer paste.
- the temperature sensor 28 is in thermal contact with the contact plate 16 in the region indicated by 29.
- the contact plate 16 will heat to a similar temperature. Due to the void 26, the region of the contact plate 16 located within the void is insulated from the heat distribution plate 24 and will more accurately reflect the temperature of the water. Since the temperature sensor 28 is in thermal communication with the contact plate 16, it senses the water temperature with greater accuracy and responsiveness. Thus, the temperature measured by temperature sensor 28 is related to the temperature of the material in the chamber 12.
- Figures 2 to 4 show the temperature sensor 28 being supported by a sensor support 30.
- the sensor support 30 is formed from silicone, and is held in place by a bracket 32. Other insulating materials are also suitable.
- the bracket 32 is mechanically fastened to the heat distribution plate 24.
- the bracket 32 is preferably formed from a relatively rigid material, such as a plastic, metal or metal alloy.
- the bracket 32 locates the sensor support 30 in the centre of the void 26 so the sensor 28 is insulated and may press the sensor support 30 against the contact plate 16, providing a good thermal connection between the sensor 28 and the contact plate 16.
- the temperature sensor 28 may be mounted in a number of ways which aim to minimise the influence of heat from the heat distribution plate 24.
- the temperature sensor 28 is typically a thermistor.
- NTC thermistors formed from metal oxides are suitable.
- a thermistor has a number of advantages over other types of temperature sensors.
- a thermistor senses the temperature of water in the kettle within a continuous range. This provides significantly more information on the temperature of the water than, for example, a bimetallic actuator.
- a bimetallic actuator is typically activated only when the water reaches a threshold temperature value and is deactivated when the water fall below a threshold temperature value. As a result, a bimetallic actuator only senses whether the water temperature is above or below a threshold value.
- the thermistor provides responsive and accurate readings because it is mounted in a thermally insulating zone in direct thermal communication with the contact platei ⁇ .
- the heater assembly 18 shown in Figures 2 to 4 has a single void 26 in which the temperature sensor 28 is located. It is also possible to have multiple voids around the temperature sensor. Each void forms a thermally insulating region. By positioning a number of the thermally insulating regions around the sensor 28, a thermally insulating zone is formed. The sensor 28 is still mounted in direct thermal contact with the contact plate 16.
- the contact plate 16 shown in Figures 2 to 4 is free of indentations, and in one arrangement is uniplanar. This shape improves the accuracy of the temperature sensor
- contact plate 16 Because the contact plate 16 is free of indentations, water contained in the heating chamber 12 of the kettle 10 is able to readily and rapidly mix. This means the temperature of water located immediately above the temperature sensor 28 is more likely to accurately reflect the temperature of the remaining water volume contained in the kettle 10. Consequently the temperature sensor 28 gives more accurate readings of the temperature of all of the water in the kettle 10.
- Other configurations of contact plate 16 may also be used.
- the contact plate may be concave or convex, or may include a dome-shaped protrusion in the vicinity of the temperature sensor 28.
- the heater assembly 18 has a heat source controller 34.
- the heat source controller is electronically connected to the temperature sensor 28 and the heating element 20.
- the heat source controller 34 controls the operation of the heating element 20 with reference to the temperature sensed by the temperature sensor 28.
- the controller 34 is made up of an electronic circuit or number of electronic circuits including a microprocessor. These circuits may be designed in a number of ways to provide the functionality described below.
- the heat source controller 34 may have a number of different functions, such as a boil function and a keep warm function, which use feedback from the temperature sensor 28.
- the functions of the kettle 10 may be operated by a button arrangement, for example one or more momentary push buttons.
- the one or more buttons are connected to, and provide input to, the controller 34.
- the controller 34 When a start button is activated, the controller 34 enters a boil mode.
- the boil mode is graphically displayed in Figure 8. Before activation, the controller 34 is in a standby mode (indicated by "Area 1" in Figure 8). After activation, the controller 34 enters the boiling mode (indicated by "Area 2" in Figure 8). When in the boiling mode, the controller 34 turns on the heating element 20 and begins to heat the water in the kettle.
- the controller 34 may in addition cause an illuminated ring to produce, for example, red light, to indicate the controller is in the boiling mode and the water is being boiled.
- the temperature sensor 28 detects when an upper boiling limit has been reached.
- the upper boiling limit may be 97°C, though other limits may be used.
- the controller enters a boiled mode (indicated by "Area 3" in Figure 8). In the boiled mode, the controller turns off the heating element 20 and the red light in the illuminated ring. The controller may then turn on, for example, a green light to indicate that the water is boiled.
- the temperature sensor 28 continues to sense the temperature of the water. After the heating element 20 is turned off, the water slowly cools. Once the temperature of the water falls to a lower boiling limit, the controller ends the boiled mode and returns to standby mode (indicated by "Area 4" in Figure 8). At this stage, the controller may turn off the green light to indicate the water is no longer at or near boiling temperature.
- a suitable lower boiling limit is 92 0 C, though other limits may also be used.
- the kettle 10 has a display for presenting data to a user.
- the display is a liquid crystal screen that may display three or more lines of alphanumeric text.
- Other types of display may also be used, including a display using light-emitting diodes (LEDs).
- the display is driven by the controller 34 and may be used to display information relating to the measured temperature and the current state of the kettle 10. As described below, the display may be used to indicate the expected time remaining until the water in the kettle boils.
- the display has three lines of text.
- the first line shows the temperature measured by the temperature sensor 28.
- the second line indicates a state of the kettle, for example "Standby", “Boiling” or “Boiled”.
- the third line shows the estimated time until the water in the kettle boils.
- Figure 5 illustrates a method 100 for predicting the time required to boil the water in the kettle.
- the method 100 may be used with the kettle 10, but may also be used with other heating vessels having a temperature measurement and a controller for predicting a time required to reach a temperature threshold.
- step 101 the temperature sensor 28 generates an electric signal indicative of an initial temperature of water in the kettle.
- the signal is provided to the controller 34.
- step 103 a user presses the start button of the kettle 10. In response to this action, the controller 34 switches on the heating element 20.
- step 105 the controller 34 monitors the output of the temperature sensor 28 and determines the rate at which the measured temperature increases. In one arrangement the rate determination may be performed by code executed by the microprocessor. Alternatively, the rate may be determined by dedicated circuitry in the controller 34 that, for example, generates a derivative of the output of the temperature sensor 28.
- the controller 34 may determine an averaged rate of temperature increase rather than an instantaneous rate. For example, the controller 34 may wait for a preset time after the heating element 20 is switched on before providing a measurement of the rate of increase of temperature. In one arrangement the controller waits for 10 seconds and then emits a rate measurement calculated as:
- T-io is the measured temperature after 10 seconds and T 0 is the initial temperature.
- the determined rate is thus the average rise over 10 seconds.
- the controller 34 may wait for a shorter time, for example 5 seconds, before providing the rate measurement.
- the display may indicate that the controller is busy calculating. For example, the word "Calculating" may appear on the display.
- the controller uses the measured rate to predict how long it will take the measured temperature to reach a temperature threshold T h r esh -
- the threshold is a temperature value that corresponds to the water boiling.
- the predicted time may be calculated using a linear extrapolation of the rate determined in equation 1 :
- T is the current temperature and T h r e s h is the specified threshold temperature.
- step 109 the time remaining is displayed.
- the controller 34 includes a clock, enabling the displayed time to be shown in a count-down manner. The displayed time thus diminishes from the value calculated in equation 2 towards zero.
- step 111 the controller 34 checks whether the current temperature has reached Tthresh- If this is the case (the Yes option of step 111 ) then in step 113 the controller 34 switches off the heating element 20 and clears the display of the remaining time.
- the controller 34 continues to monitor the rate of temperature increase, as this enables the time prediction to be updated. For example, if water is added to the kettle 10 the current temperature can change, affecting the time required to reach Tthr e s h - If the controller 34 determines that the current temperature has not been reached (the No option of step 111), control flow returns to step 105 to obtain an updated value for the rate of temperature increase. The updated rate is then used in step 109 to revise the time prediction using equation 2.
- the updated value of the rate is preferably an averaged value, for example the average increase in the previous 5 or 10 second interval.
- the displayed value changes. For example, if water is added to the kettle 10, the displayed 'time until boiling' increases.
- the method 100 may also include safety checks. For example, if the rate of temperature increase determined in step 105 is greater than or equal to a specified upper value, the controller may act to cut off the heating element. This condition may arise if the kettle is empty or if the contents have boiled away. Reheating
- the controller 34 determines a pulsed mode of operation for the heating element 20 that would reheat the water in the kettle to the threshold temperature.
- step 115 the controller 34 monitors the output of the temperature sensor 28 and determines a rate of temperature decrease after the heat element 20 has been switched off. Then, in step 117 the controller 34 determines a pulsed cycle of operation for the heating element 20 that, if applied, would return the contents of the kettle to the threshold temperature.
- the kettle 10 may have two or more heating modes dependent on the load, i.e. the amount of liquid in the kettle. Low volumes of liquid heat up more rapidly than larger volumes.
- the rate of change of temperature measured in step 105 thus provides an indication of the load of the kettle.
- the controller 34 may select a temperature threshold based on the rate of change. If low volumes are deduced (i.e. the rate of change of temperature lies in a specified higher range), then the heating element 20 is switched off at a reduced threshold. In the boiling mode, a reduced threshold for boiling of 93 0 C is suitable, although other values may be used.
- the heating element 20 is switched off at a higher threshold, for example 97 0 C.
- the controller 34 monitors the rate of change of measured temperature on a regular basis and, if necessary, changes the temperature threshold based on the current rate of change. Thus, for example, if cold water is added to the kettle 10, the controller 34 may need to switch to a heating mode that uses a higher temperature threshold.
- the controller 34 may have a look-up table that lists suitable thresholds corresponding to different rates of heating.
- the load may be inferred from measurements other than the rate of change of temperature.
- Such alternative load measurements include the level of liquid in the kettle or the weight of the kettle.
- a reed switch or capacitive sensor may be used to indicate the level in the kettle.
- the controller 34 may select a higher or lower threshold dependent on whether the level of fluid is above or below a threshold value.
- FIG. 6 illustrates a method 200 of selecting the temperature threshold
- the temperature sensor 28 generates a temperature signal that is related to the temperature of the water in the kettle 10.
- a load signal is generated that is related to the amount of liquid in the kettle.
- the load signal corresponds to the rate of temperature change determined by the controller 34 in step 105.
- the controller 34 selects a temperature threshold value.
- the threshold value may be read from a look-up table stored in memory or data storage of the controller 34.
- the selected value is used in step 107 to predict the time required for the water in the kettle to reach the threshold.
- Figure 7A is a graph of the heating element voltage versus time.
- Reference numerals 301-307 indicate points on the graph, and
- Figures 7B to 7H show the data that is displayed on the kettle display at the respective points.
- the kettle is in standby mode and at point 301 the display indicates a measured temperature of 22 0 C and a state of "Standby".
- the voltage across the heating element 20 is 0 V.
- the kettle is switched on, for example by a user pressing the "boil” button.
- the heating element 20 is switched on and the display indicates that the kettle is in the "Boiling" state.
- the temperature is still 22 0 C.
- the display shows that the controller 34 is calculating.
- the voltage across the heating element 20 is switched off.
- the temperature has risen to 25 °C, and the display still indicates that the controller 34 is calculating.
- the display shows a predicted time of 4 minutes 7 seconds until the kettle reaches the specified threshold temperature, which in the example is 97 0 C.
- the controller 34 may select a different threshold temperature if the rate of temperature increase is higher.
- the time shown on the display decreases and at point 305 the predicted time until boiling is 2 minutes 3 seconds. As seen in Figure 7F, the measured temperature has reached 62 0 C.
- the measured temperature reaches the designated threshold temperature of 97 0 C and, as seen in Figure 7G, the display shows that the kettle 10 is in a "Boiled” state and has returned to standby, with the heating element switched off.
- the temperature gradually cools and at point 307 the temperature has dropped to 96 0 C. Once the temperature is below the lower limit (e.g. 92 0 C), the display no longer shows the "Boiled" indication.
- a graphic display may be used.
- a bar graph may indicate the overall time to reach the threshold, overlaid with a second bar graph indicating what proportion of the total time has elapsed. If the predicted overall time changes, the proportion indicated by the second bar graph is adjusted accordingly.
- Other graphic objects may also be used, for example a circle indicating the predicted overall time with an incrementing pie-segment showing the proportion of time that has elapsed.
- the principles of the present invention may be applied to other types of heating vessels, such as percolators, mocha makers, rice cookers, slow cookers and electric fry ware.
- the vessel has an electronic sensor that provides an indication of the temperature of the vessel contents.
- the vessel also has a controller for predicting how long it will take for the contents of the vessel to reach a specified temperature and a display for displaying the predicted time.
