Definitions

  • the present invention relates to a control for an oven and a method of controlling an oven.
  • Ovens which can provide a variety of functions within a single cooking volume, such as fan oven, convection oven and grill are known, The various modes are conventionally selected using a rotary switch.
  • a rotary switch only allows selection of particular oven functions which correspond to a particular position of the rotary switch.
  • the present invention provides a control and a method of controlling an oven which allows any combination of oven function to be selected by a user at any point in operation of the oven.
  • the present invention also provides a method of controlling an oven which provides indication to a user to indicate functions which are available for selection or which have been selected.
  • an oven control comprising input means; and a processor for controlling at least first and second oven functions in response to an input signal from the input means; wherein the processor is adapted to activate the second oven function in response to user input from the input means whilst the first oven function is in operation.
  • a user can therefore exercise a high degree of control over the oven at all stages in the cooking process.
  • the user can choose to activate an additional oven function at any time in the cooking process and is not limited to preselected combinations chosen by the manufacturer at the time of manufacture.
  • the user can choose to activate a grill element to give additional browning without needing to alter the existing cooking settings, such as the temperature of a fan oven.
  • a conventional rotary switch it is not possible to select a grill element without first turning off the fan oven.
  • other ovens such as combination microwave ovens, it is not possible to select an additional oven feature, for example a grill element, during cooking without first cancelling existing cooking settings.
  • the input means may comprise a plurality of buttons.
  • the term "button" is intended to include all means of selection in which an item is pressed by a user. It therefore includes push buttons and also touch sensitive panels where a user may press a section of the panel.
  • the processor is further adapted to determine the combined operating requirement of the first and second oven functions and, if the combined operating requirement of the first and second oven functions is more than a predetermined limit, to reduce the operating requirement of the first oven function before activating the second oven function to ensure that the predetermined limit is not exceeded.
  • any installation of an oven will be subject to constraints on it's operating requirements.
  • the operating requirements define constraints on the oven's operation, for example the maximum power (in watts) or current (in amps) which can be drawn from the power supply. It is possible that a user may select a combination of features which will exceed that permitted, possibly resulting in damage to the oven or power supply.
  • the processor can prevent the oven from exceeding predetermined limits. This improves the safety of the oven and allows the user freedom to select any combination of oven functions. Existing ovens with rotary switches circumvent this issue by only allowing a single oven function to be selected at one time.
  • a method of controlling an oven comprising:
  • the method further comprises, before the step of activating the second oven function:
  • An additional oven function can therefore be added without danger of exceeding the permitted maximum operating requirements.
  • an oven control comprising:
  • buttons By using the first and second indication state, the control can easily guide a user in which functions are available for selection or have been selected.
  • buttons is intended to include all means of selection which can be pressed, including push buttons and touch sensitive panels.
  • the indicia are incorporated into the buttons themselves. This embodiment is particularly suitable for touch sensitive panels.
  • the processor is further adapted to determine whether further user input is required before the selected oven function can be activated and, if it is determined that further user input is required, to display indicia of the further user input required in a third indication state.
  • the processor can guide a user to enter the correct information. For example if a user selects the convection oven function, the processor can indicate to the user that a temperature is required to be input.
  • a method of controlling an oven comprising:
  • said step of activating the selected oven function further comprises:
  • the method can therefore guide a user in operation of the oven by the use of different indication states.
  • the first, second and third indication states are preferably different colours.
  • the first and second indication states may be different colours with the third indication state being flashing of the indicia.
  • the oven control of the first and third aspects may be combined into a single control. Likewise the methods of the second and fourth aspects may also be combined.
  • Figure 1 depicts the surface layout of a control according a first embodiment of the invention.
  • the control is for controlling a dual oven with a main oven and a top oven.
  • a first button cluster 10 is provided on the left hand side to control the main oven and a second button cluster is provided on the right hand side to control the top oven.
  • a third button cluster 30 provides control to set the oven timer.
  • a central rotary press switch 40 is provided in the centre of the control.
  • Either side of rotary press switch 40 are windows 52, 54 for displaying information such as cooking temperature and cooking time.
  • each window covers four seven-segment numerical LED indicators.
  • Button clusters 10,20, 30 are all of the touch sensitive type.
  • a light an LED in this embodiment, is located behind each button.
  • the majority of the control is coloured black, indicating that light cannot be transmitted through it.
  • Each of the buttons incorporates a clear section forming an indicia of its purpose. The LED can shine through the clear section illuminating the button.
  • the LEDs are of the type which can emit a different colour of light depending on the applied voltage. LEDs which can be emit both red and green light are preferred.
  • the control further comprises a processor (not illustrated) which is connected to the button clusters 10, 20, 30, the central rotary switch 50 and the LEDs behind the buttons and clear windows 52, 54.
  • the processor can control the LEDs to be on or off, to be a particular colour and, for the LEDs behind the clear windows 52, 54, to display particular numerical information.
  • the processor may be implemented by a microprocessor, Application Specific Integrated Circuit, Field Programmable Gate Array, or any other suitable electronic device.
  • the processor is used to control the oven functions in response to user input on the control.
  • the operation of the control will now be described.
  • a user presses the central rotary press switch 40.
  • the processor then activates the buttons in clusters 10 and 20 to indicate oven functions that can be selected.
  • a red light is used to indicate functions which can be selected.
  • the user selects a particular function by pressing the relevant button. For example the user may press button 11 which indicates that the main oven is required to function as a fan oven.
  • the processor receives the user input and changes the colour of button 11 to green to indicate that the function has been selected. It is then determined whether further user input is required. In this case, input of the temperature of the oven is required.
  • the microprocessor then displays a flashing red temperature in window 52. This functions as a prompt to the user to rotate the rotary press switch 40 to set the desired temperature.
  • the processor monitors the period between input signals received from it. In the event that no further input signal is received after a predetermined period, for example 3 seconds, the processor determines that the correct temperature has been selected. The temperature thus chosen is then displayed in window 52 in solid green (not flashing) to show it has been selected.
  • the processor displays in red additional oven functions which can be set in addition to the fan oven.
  • the processor may light buttons 12, 13, and 14 which indicate additional heating elements within the main oven which the user can choose to activate if required.
  • the processor also displays button 31, which is to set the timer, in red.
  • the processor determines that button 31 has been pressed it displays a flashing time period in red in the right hand window 54.
  • the user can then rotate the rotary press switch 40 to select the desired time.
  • the processor determines that the correct time has been set when there is no input from the rotary press switch 40 for a predetermined period, for example 3 seconds.
  • the time in the second window 54 is then stopped from flashing and turned green to indicate that it has been set.
  • Button 31 is also shown in green.
  • the processor changes the displayed time in window 54 to indicate the remaining cooking time.
  • buttons 32 in red This button is used to set a desired time when cooking should be complete.
  • an end time is displayed in red in window 54.
  • the processor displays button 32 in green.
  • the processor also calculates the correct starting time by subtracting the cooking time from the ending time. The oven is then turned on at the starting time so that the food is ready at the required ending time.
  • the processor determines that one of buttons 12, 13 or 14 has been pressed, it first checks what the combined operating requirements (for example power consumption or current requirement) of the currently active oven function in combination with the newly selected oven function is. This is compared to predetermined limits, for example 3kW or 13 Amps. If the operating requirement is higher than the limit, the processor reduces the power or current supplied to the currently active oven function (in this case the fan oven) before it activates the newly selected function to ensure that the oven does not exceed the limit.

If the operating requirement is higher than the limit, the processor reduces the power or current supplied to the currently active oven function (in this case the fan oven) before it activates the newly selected function to ensure that the oven does not exceed the limit.
  • This checking of operating requirements is also applied to selection of oven functions in the top oven from button cluster 20 both when the top oven only is in use and when both the main oven and top oven are in use. This is especially useful when the top and main ovens share a common power supply.
  • LEDs may be used instead of LEDs.
  • other forms of display may be used instead of LEDs.
  • LCDs Liquid Crystal or florescent displays.
