Abstract
Description
- The present invention relates to a cooking oven, in particular a domestic electrical oven.
- Domestic cooking ovens usually comprise a housing with a cooking cavity which delimits inside a cooking space for accommodating the food to be cooked. The cooking cavity has an access opening which can be closed by means of a door hinged to the housing.
- In order to heat the cooking space, the cooking cavity is provided, at its lower and upper walls, with heating elements typically formed by electrical resistors.
- In order to obtain a preferably uniform distribution of the heat in the cooking space, the electrical cooking ovens comprise an air circulation system in the cooking cavity. Typically, such an air circulation system comprises an impeller operated by an electrical motor in flow communication with the cooking cavity so as to be able to generate an air circulation in the cooking space.
- In order to avoid the overheating of electrical or electronic components of the oven as well as burns to the user during use of the cooking oven, it is known to cool such thermally sensitive components and/or a grip zone of the door by means of a cooling air stream.
- For such purpose, the ovens of the prior art may comprise a fan placed in a cooling compartment arranged over the cooking cavity and which can be operated to suck ambient air, e.g. through an intake opening formed in a rear wall of the housing, and to direct it towards the thermally sensitive components and/or through a horizontal slot of the front wall of the oven in the anterior front zone (grip zone) of the oven door.
- Traditionally, the cooling of the thermally sensitive components of the oven is activated when the oven is switched on and remains on for the entire operating time of the oven until it is switched off. This ensures fully safe operation of the oven and avoids undesired overheating at the cost of a permanent consumption of electrical energy.
- The ventilating of the cooking space may be turned on or off by the user as a function of the cooking recipe. Once on, the ventilating of the cooking space remains permanently on until it is switched off manually regardless of the operation of the heating resistors of the oven. Thereby, the ventilating of the cooking space also implies a permanent consumption of electrical energy.
- More recently, intermittent cooling systems have been suggested provided with a sophisticated control to optimize the cooling of thermally sensitive components or cooking parameters of particular food.
- Compared with the traditional ovens, the more sophisticated ventilating control systems also comply with the energy saving needs but require more complex electronic or electrical controllers which, in turn, are costly and subjected to fault and malfunctioning. Furthermore, even renouncing permanent ventilating of the oven the residual risk of overheating cannot be excluded.
- It is the object of the present invention to suggest a cooking oven, in particular of the domestic electrical type having features to better conciliate the needs of:
- reducing the energy consumption of the oven,
- simplifying and reducing the oven fan control system costs,
- maintaining or increasing the anti-overheating safety of the oven.
- In other words, the control system automatically switches on the fan together with switching on the heating means and automatically switches the fan off together with switching off the heating means so that the fan is actuated intermittently in a synchronized manner with the actuation of the heating means.
- Thereby, each step of heating of the cooking cavity is automatically and permanently accompanied by the ventilation of the thermally sensitive region of the oven (e.g. cooking cavity and/or thermally sensitive components, door) thus effectively avoiding the risk of overheating. Furthermore, during all periods in which the heating of the cooking cavity is deactivated and there can be no further increase of the thermal energy accumulated therein, the ventilation of the thermally sensitive region to which the fan is associated is deactivated and the respective consumption of electrical energy is canceled out.
- Finally, the joint switching of the heating means and of the electrical fan makes the control system simpler and more robust because both functions can be managed with the same electrical control circuit.
- In order to better understand the invention and appreciate its advantages, some non-limitative embodiments will be described below with reference to the figures, in which:
