  • the method comprises delaying heating of the two or more heating elements until the position information of the food item has been obtained.
  • the present disclosure has applicability to ovens that are suitable for heating food.
  • Such ovens may be used in a domestic setting (e.g. a user's home), or in a commercial setting (e.g. a restaurant or café).
  • a user When using such an oven a user typically places food to be cooked on to a tray or shelf in the oven.
  • the food may be placed directly on to the shelf, or be contained in a receptacle such as a baking tray or pot.
  • the food can be moved between two or more set positions in the oven, for example a top portion of the oven, a middle portion of the oven, or a lower portion of the oven (for example by moving the shelf, or selecting between two or more available shelves).
  • the user can also set a cooking or heating temperature of the oven via a user interface of the oven.
  • the temperature set by the user may be indicative of a temperature that will be experienced at or near the centre of the oven.
  • the actual temperature which the food to be heated is subjected to may be dependent upon where in the oven the food is placed, for example whether it is in the top portion, middle portion or lower portion. For example, if the oven has a single heating element at the top of the oven, and the food is placed in the lower portion of the oven, then the food may be cooked at a lower temperature than was intended and set by the user.
  • Some ovens comprise more than one heating element.
  • an oven may comprise a top heating element at the top of the oven, and a bottom or lower heating element at the base of the oven. If food to be heated is placed in the lower portion of the oven, then the top of the food may be subject to a temperature lower than intended and set by the user, whilst the bottom or underside of the food may be subjected to a temperature higher than that intended by and set by the user. Again, this may lead to improperly cooked food. Improperly, unevenly or undercooked food may harm a user, for example may lead to burns in a mouth of the user or may lead to food poisoning. Furthermore, it may lead to annoyance of the user, and give the user a negative perception of the oven in question.

In some examples it may be considered that a controlled temperature of two or more heating elements in the oven is proportional to a distance of the two or more heating elements to an item of food to be heated.
  • the two or more heating elements are activated only once the position information of the food to be heated has been obtained.
  • the controller 156 may be configured to delay heating of the two or more heating elements until the position information of the food item has been obtained. For example a user may turn the oven on and set a temperature of 200°C prior to placing the food in the oven.
  • the controller 156 will activate the two or more heating elements 112, 114, 116 and 118 (i.e. start heating the two or more heating elements) only once the food has been placed in the oven and the position information of the food has been obtained.
  • the controller 156 will activate the two or more heating elements 112, 114, 116 and 118 only once the food has been placed in the oven and the position information of the food has been obtained, and it is detected that the door 146 of the oven has been closed. Detecting that the door 146 is closed may, for example, be carried out by the controller 156 receiving a signal from a switch indicating that the door 146 has been closed.
