Definitions

  • the present invention regards an oven for cooking food products and a method for cooking food products with the aforesaid oven according to the preamble of the independent claims.
  • the present oven is advantageously employable for cooking food products at its interior, preferably baked, and is intended to be employed in a professional setting, for example in the bakery field, gastronomy field, pastry field and in the restaurant field in general, as well as in the home.
  • the present invention is inserted in the industrial field of production of apparatuses for cooking food products, in particular ovens, both of professional and home type.
  • ovens for cooking food products provided with a support structure defining, at its interior, a cooking chamber.
  • Such ovens comprise at least one cooking surface, made of steel or alternatively of refractory material and placed in proximity to a base wall of the support structure, and one or more electrical heating elements placed within the cooking chamber, usually on the upper wall and on the base wall delimiting the cooking chamber, in order to allow the cooking of the food products placed at the interior.
  • the aforesaid ovens comprise an ambient temperature sensor, usually a thermocouple, placed within the cooking chamber and arranged for measuring the temperature inside the oven, also known as chamber temperature.
  • the ovens of known type in an entirely conventional manner, allow the user to select a specific cooking program, which corresponds to a specific power of the electrical heating elements, and such ovens comprise a selector of the internal temperature of the chamber, by means of which the user can set the objective temperature that the cooking chamber must reach before putting the food in the oven.
  • the conventional ovens also comprise at least one signaling LED, operatively connected to the temperature sensor and arranged for communicating - for example by means of the turning off or turning on thereof - to the user when the cooking chamber reaches the temperature set by the user or the temperature corresponding to the preset program.
  • the ovens for cooking food products of known type have in practice shown that they do not lack drawbacks.
  • a first drawback of the ovens of known is given by the fact that they do not allow obtaining a cooking of the foods that is always optimal and reproducible, in particular during multiple continuous cooking cycles.
  • ovens provide the user with a visual feedback, given by the signaling LED, indicative of the temperature inside the cooking chamber, which however is not a sufficient condition for attaining an optimal cooking that is reproducible over time.
  • the internal temperature of the cooking chamber is very different from the temperature of the cooking surface, for example in the first starting steps of the oven (with the cooking surface that is situated at a temperature much lower than the temperature of the chamber).
  • a further drawback lies in the fact that such ovens do not allow an optimal cooking if it is necessary to cook products that require temperatures that are very different from each other. For example, in the event in which following the cooking of a first food for which high temperatures within the chamber are required, it is necessary to change cooking program in order to cook a second food at low temperatures, the user will tend to put the aforesaid second food in the oven as soon as he/she receives the visual feedback that the objective chamber temperature has been reached, without considering if also the cooking surface has reached or not reached such objective temperature.
  • the cooking quality of the various food products to be baked and the reproducibility thereof will depend on the experience of the user and his/her capability in understanding the actual situation of the cooking chamber and the cooking surface before cooking the food products.
  • thermocouple embedded in the cooking surface in order to detect the internal temperature of the latter.
  • a grill for cooking foods which comprises a thermal camera, grippable and manually actuatable by a user, which is configured in order to detect the temperature of the foods placed on the grill and automatically recognize the shape of such foods such to be able to recognize which are the different foods that have been placed on the grill.
  • the problem underlying the present invention is therefore that of eliminating the problems of the abovementioned prior art, by providing an oven for cooking food products which allows obtaining an optimal cooking for the different food products to be cooked.
  • a further object of the present invention is to provide an oven for cooking food products which allows obtaining a cooking which can be reproduced over time with precision.
  • a further object of the present invention is to provide an oven for cooking food products which is simple to use.
  • a further object of the present invention is to provide an oven for cooking food products which is adapted for the aforesaid objects even in a home environment for users without professional experience.
  • a further object of the present invention is to provide an oven for cooking food products which allows guiding the user during the different cooking operations.

  • the present method comprises a cooking step, in which the first comparison module C1 compares the surface temperature value Ts detected by the first temperature sensor 6 and the second threshold surface temperature value Tss2 of the food product 100 placed on the cooking surface 4 and sends a corresponding second comparison signal to the user interface 8 in order to signal to the user when the food product 100 has reached the surface temperature associated with an optimal cooking level.
  • a step is preferably provided for extracting the food product 100 from the cooking chamber 3. More in detail, the user removes the food products 100 from the cooking chamber 3 of the oven 1 when the user interface 8 emits the aforesaid warning signal.
  • the user inserts the food product 100 within the cooking chamber 3, in particular placed on the cooking surface 4, when the latter has reached the ideal temperature for cooking the specific food product 100.
  • the user removes the food product 100 from the cooking chamber 3 when the latter has reached a surface temperature associated with an ideal cooking level for the specific food product 100.
  • the invention thus conceived therefore attains the pre-established objects.
