Definitions

  • an oven comprising a calibration system which continuously measures the temperature in the oven and bring the humidity measurement algorithm to the ideal humidity measurement values by controlling the erroneous measurements caused by changing temperatures due to environmental or physical factors.
  • the aim of the present invention is the elimination of all the disadvantages and limitations of the humidity measurement mechanisms in the above-mentioned ovens by realizing an arrangement for humidity measurement which detects levels in a simple and reliable manner based on a different physical principle.
  • Another aim of the present invention is the realization of an oven which provides quality cooking by ensuring that the humidity encountered in the ovens, especially in the cooking ovens, where foodstuffs are generally cooked under very high temperature conditions, is regulated at preset levels so as to obtain high performance, regardless of the type and amount of foodstuff.
  • the oven of the present invention comprises a user interface which is in communication with the control unit and which has a calibration mode activated by the user at any time during the cooking process to enable the control of the amount of humidity in the cooking chamber.
  • the humidity measurement mechanism (5) comprises a sensor block (5.5) which is embedded on the body (3) and which has at least one first temperature sensor (5.1) extending from one end to the cooking chamber (2) and measuring the temperature of the body (3) heated by the air circulation in the cooking chamber (2), a cooling member (5.2) cooled by at least one second fan (5.4) and at least one second temperature sensor (5.3) measuring the temperature of the air blown by the second fan (5.4); and at least one third temperature sensor (5.6) which measures the temperature of the air circulated in the cooking chamber (2).
  • a sensor block (5.5) which is embedded on the body (3) and which has at least one first temperature sensor (5.1) extending from one end to the cooking chamber (2) and measuring the temperature of the body (3) heated by the air circulation in the cooking chamber (2), a cooling member (5.2) cooled by at least one second fan (5.4) and at least one second temperature sensor (5.3) measuring the temperature of the air blown by the second fan (5.4); and at least one third temperature sensor (5.6) which measures the temperature of the air circulated in the cooking chamber (2)
  • the cooking temperature (T1) of the foodstuffs in the cooking chamber (2) as well as the temperature (T2) of the cooking vessel are measured by the third temperature sensor (5.6).
  • the temperature (T3) of the hot air circulating in the cooking chamber (2) is also measured by means of the first temperature sensor (5.1) which is positioned at the point of contact of the sensor block (5.5) with the cooking chamber (3) as embedded in the body (3) and extending towards the cooking chamber (2).
  • the temperature of the body (3) is particularly subject to direct contact with the hot air circulating in the cooking chamber (2).
  • the relationship between the said calculated heat transfer coefficient and the instantaneous oven interior humidity value is expressed empirically.
  • the humidity of the cooking chamber (2) can be measured by generating an empirical expression with the said three parameters (T1 or T2, T3 and T4).
  • the oven (1) comprises a user interface (7) which is communication with the control unit (6) and which has a calibration mode (7.1) activated by user selection to enable the control of the amount of humidity in the cooking chamber (2) at any time during the cooking process.
  • the oven (1) comprises a user interface (7) which has a calibration mode (7.1) activated by user selection to control the amount of humidity in the cooking zone (2); and a control unit (6) which is in communication with the user interface (7) and at least one temperature sensor (5.1, 5.3, 5.6) in the humidity measurement mechanism (5), which can be positioned at any point on the body, which compares a predetermined ideal reference humidity value (RH1) with the humidity value (RH2) calculated instantly according to the data received from the said temperature sensors (5.1, 5.3, 5.5), and which, if the humidity value (RH2) resulting from the said calculation is different from the said reference humidity value (RH1), changes the predefined ⁇ , ⁇ and ⁇ coefficients for the said T1 or T2, T3 and T4 temperature values, respectively, to approach the said reference value (RH1).
  • a predetermined ideal reference humidity value (RH1) with the humidity value (RH2) calculated instantly according to the data received from the said temperature sensors (5.1, 5.3, 5.5
  • RH1 predefined
  • a predefined amount of water for example 1 liter, is placed in the cooking chamber (2).
  • the temperature value reached by the oven (1) during the cooking process and the ideal reference humidity value (RH1) formed in the oven (1) are defined as a predetermined value in the control unit (6).
  • the user activates the calibration mode (7.1), and in the calibration program, when the reference humidity value (RH1) and the instantaneous humidity value (RH2) measured in the oven (1) differ according to the humidity level of the water evaporated at a constant temperature during the cooking process, the control unit (6) changes the predefined ⁇ , ⁇ and ⁇ coefficients of the T3, T4 and T1 or T2 temperature values measured by the temperature sensors (5.1, 5.3, 5.5), respectively, and brings the predefined reference humidity value (RH1) and the instantaneous humidity value (RH2) measured in the oven (1) closer to each other.
