Definitions

  • the present invention relates to an oven wherein the cooking efficiency is improved.
  • temperature probes stuck into the food are used for an exact measurement of the inner temperature of the food during cooking. These probes are generally named as meat probe.
  • the temperature data received from the sensor that is located at the portion of the probes remaining inside the food is transmitted to the control circuit of the oven by a cable covered with heat insulating material.
  • the control card which also arranges the operating times of the oven, detects that the food is fully heated or baked and hence terminates the cooking process.
  • Most of the probes with a simpler structure have a temperature indicator on them and do not contribute to the cooking process of the oven; only the temperature data written thereon can be read by the user.
  • a cordless probe which is used for measuring the inner temperature of the food to be baked that is disposed into the oven.
  • a latch that moves at the portion of the probe remaining inside the food when heated, lights the bulb at the top portion of the probe that remains outside the food.
  • the photosensitive means disposed in the inner volume of the oven transmits the data that the food is baked to the oven control circuitry according to the light emitted from the probe.
  • this system does not provide an exact detection of the temperature of the food and the transmission of it to the user.
  • the photosensitive means cannot detect the light of the probe.
  • the aim of the present invention is the realization of an oven that provides a cooking exactly at the desired degree.
  • the oven comprises a cooking chamber wherein foods to be baked are disposed, a probe which is stuck into the food and which measures the inner temperature of the food, and a control unit which arranges the cooking process.
  • the probe has a long, thin structure in order to be placed into the food easily.
  • the probe comprises a detector and an electronic circuit which emits the temperature data received from the detector by an antenna that is located at the portion of the probe remaining outside the food.

  • a receiver receives these signals, reconverts them to digital signals and transmits them to the control unit.
  • the control unit controlling the cooking time by turning the heaters on and off at determined intervals, receives instant inner temperature data of the food and hence arranges the control mechanism accordingly.
  • the probe comprises a circuit at its portion remaining inside the food.
  • the area wherein the circuit is located is protected from the heat of the cooking chamber without the need of covering it with a separate insulating material.
  • the food is baked when the inner temperature rises up to a temperature whereat the circuit will not be damaged and the food is taken out of the oven.
  • the inner temperature of the food can be measured exactly and transmitted instantly to the control unit.

  • the cooking situations according to varieties of food can either be controlled by temperature increases or can be controlled by changes in moisture. For example, even though the temperature of cake reaches the desired level, its inner portion can remain moist. Therefore, the data received from the detector (5) that measures the amount of moisture inside the food plays an important role for arranging the cooking algorithm.
  • the oven (1) comprises a control unit (4) that directs the cooking algorithm by the data received from the circuit (6).
