Definitions

  • the present invention relates to a cooking oven, particularly a household electric oven, provided with a humidification device.
  • Household electric ovens usually comprise a housing with a cooking recess defining therein a cooking space to receive the dishes to be cooked.
  • the cooking recess is surrounded by a layer of thermoinsulating material, and has an access opening which can be closed by means of a door which is hinged to the housing forming the household appliance outer covering.
  • the cooking recess is provided, at the lower and upper walls thereof, with heating members typically composed by armoured tube resistors.
  • the lower heating member is typically arranged outside the cooking space, between the cooking recess lower wall and the thermoinsulating layer, so as to heat the dishes, particularly those in the cooking space lower part, through such lower wall.
  • the upper heating member is typically composed of a resistor which is coil-shaped and arranged inside the cooking space, adjacent the cooking recess upper wall, so as to heat the dishes, particularly those in the cooking space upper part, by convection and thermal irradiation.
  • the electric cooking ovens comprise an air ventilation and circulation system.
  • air circulation system provides a fan wheel actuated by a electric motor, and in flow communication with the cooking recess, so as to be able to generate a circulation of the air in the cooking space.
  • further heating members for example, resistors, in the path of the air flow generated by the fan wheel, so as to heat the air circulating downstream the cooking recess, and before the air laps against the dishes arranged in the cooking space.
  • Cooking ovens having a humidification function for the cooking environment further comprise a humidification device which injects moisture into the cooking recess. This allows an improved preservation of the foods organolectic properties, and a reduced weight loss due to fluid leakages, which is an important aspect while cooking meats, which keep their own juices therein, thus remaining soft and tasty.
  • the cooking recess humidification obviates an undue drying, with relative loss of vitamins and mineral salts.
  • a further known advantage of the cooking ovens having a humidification function is that, during the cooking of breads and derivates, the moisture ensures elasticity and softness also to the outer layer of the dough, thus avoiding crust tearing during a volume increase.
  • the cooking recess humidification is achieved by boilers which develop vapour, or by water atomization pneumatic devices.
  • Such known systems while being satisfactory as regards humidification, are expensive and technically complex.
  • the vapour generators consume a considerable amount of electrical power, on the order of hundreds of Watts, and require special anti-explosion safety measures for the boiler.
  • DE 10 2005 059505 A1 discloses a cooking oven having features of the preamble of claim 1.
  • object of the present invention is to propose a cooking oven with humidification device, particularly of the household electrical type, having such features as to obviate at least some of the drawbacks cited with reference to the prior art.
  • a further object of the present invention is to propose a cooking oven with humidification device which has a simplified structure, does not require anti-deflagration safety measures, and has reduced power consumes.
  • the piezoelectric aerosol generator in contact with the water to be converted into moisture expands and shrinks in response to a potential difference applied to the piezoelectric crystal, thus applying a high frequency vibration (in the ultrasound range) to the water, such as to generate an instantaneous, cold aerosol flow.
  • a cooking oven 1 comprises a housing 2, inside which a cooking recess 3 is arranged, preferably wrapped in a layer of thermoinsulating material, and intended to receive the dishes to be cooked.
  • the cooking recess 3 is defined by an upper wall, a lower wall, a rear wall, and side walls provided with sliding guides adapted to slidingly support shelves 5 of the "grid” or “sheet” type, which can be withdrawn from the cooking recess 3 through an access opening, which can be closed by means of a door (not shown) preferably secured to the oven 1 housing 2.
  • the oven 1 further comprises a suction system to suck fumes and vapours from inside the cooking recess 3.
  • the suction system comprises air inlet openings arranged in the housing 2 lower part, and air outlet openings preferably arranged in the housing upper front part.
  • the inlet and outlet openings are mutually connected through a tubing system (not shown) inside which an air flow is created, by means of so-called “tangential” or “entrainment” ventilating means 6.
  • Such entrainment flow creates a suction inside a jointing tube connected to the tubing opening with one attachment end thereof to the cooking recess.
  • the oven 1 is provided with heating means, for example, resistors 4 or, in the case of gas ovens, with burner units which are arranged outside and/or inside the cooking recess 3.
  • heating means for example, resistors 4 or, in the case of gas ovens, with burner units which are arranged outside and/or inside the cooking recess 3.
  • a lower heating member is arranged outside the cooking space between the cooking recess 3 lower wall and the thermoinsulating layer, so as to heat the dishes, particularly those in the cooking space 3 lower part, through such lower wall.
  • a further upper heating member consisting in a coil-shaped resistor, is arranged inside the cooking recess 3, adjacent the upper wall thereof, so as to heat the dishes, particularly those in the cooking recess upper part, by convection and thermal irradiation.
  • the upper heating member comprises an infrared and/or thermal irradiation plate secured to the cooking recess 3 upper wall.
  • a ventilation space is obtained, which is provided in flow communication with the cooking recess 3 through one or more suctioning openings and one or more ventilation openings obtained in at least one of the walls defining and separating cooking recess 3 and ventilation space one from the other.
  • a recirculating fan wheel 7 is arranged, which can be actuated by an electric motor and which is intended to mix the air inside the cooking recess 3.
  • the recirculating fan wheel 7 is adapted to suck air from the cooking recess 3 through the suctioning openings in the ventilation space, and to input air from the ventilation space back into the cooking recess 3 through the ventilation openings. In this manner, the recirculating fan wheel 7 generates an air flow in the cooking recess 3 which extends from the ventilation openings through regions in which the air laps against the dishes arranged in the oven up to the suctioning openings.
  • one or more further heating members can be provided, for example, resistors arranged in the path of the air flow generated by the recirculating fan wheel 7.
  • the cooking oven 1 further comprises a humidification device 10 with water amount supplying means which is sufficient to the generation of moisture, for example, a water reservoir 11 arranged outside the cooking recess 3 but inside the housing 1 or, alternatively, a water duct connectable to a water source outside the oven.
  • a humidification device 10 with water amount supplying means which is sufficient to the generation of moisture, for example, a water reservoir 11 arranged outside the cooking recess 3 but inside the housing 1 or, alternatively, a water duct connectable to a water source outside the oven.

  • the water reservoir 11 can be removably housed in a seat which is accessible by the user, in order to allow the filling thereof, or a filling opening can be provided which is accessible from outside the oven, and which is in flow connection with the same reservoir 11.
  • a level indicator 20 can be provided, preferably arranged on the oven front side, in the proximity of the handles 9 for the cooking program setting and selection.
  • Such level indicator 20 can be operatively connected to a float in the reservoir 11, with discrete level sensors in the reservoir, or it can comprise an indicator tube communicating with the reservoir 11 so that the water level in the indicator tube is identical to the water level in the reservoir.
  • the humidification device 10 further comprises an atomization tank 12 adapted to contain a water portion in contact with a piezoelectric aerosol generator 13, which will be described herein below.
  • the atomization tank 12 is configured as a container separated from the reservoir 11 and supplied therefrom through a feeding opening 25.
  • the feeding opening 25 is preferably obtained in the reservoir 11 lowermost point, so that the water is conveyed to the atomization tank by the force of gravity.
  • the reservoir 11 can be connected to the atomization tank 12 through a capillary tube duct or a suction duct, so that the liquid which the reservoir 11 holds can be conveyed into the atomization tank 12 through a suction induced by a pressure differential between reservoir 11 and atomization tank 12, and under the capillary action in the same tube.
  • Valve means 26 are provided which are adapted to control the water passage through the feeding opening as a function of the water level in the atomization tank and as a function of the water level relative to the piezoelectric aerosol generator 13.
  • the valve means 26 may comprise a float valve, or a valve which, during the closure thereof, is stressed by an elastic preload, such as to ensure a closure of the feeding opening 25 whenever a preset upper water level suitable to a piezoelectric aerosol generator 13 proper functioning is achieved or exceeded in the atomization tank and, similarly, an opening of the feeding opening 25 whenever the water in the atomization tank reaches or falls below a preset lower water level suitable to the piezoelectric aerosol generator 13 proper functioning.
  • the atomization tank 12 can be arranged beneath the cooking recess 3 or laterally relative to the cooking recess 3. As already described with reference to the reservoir 11, the atomization tank 12 can also be configured as a fitting which can be withdrawn from and inserted into a special seat obtained in the housing 2, or as a fixed component of the oven. In order to allow the atomization tank 12 emptying, a waste pipe 21 can be provided which can be closed by means of a plug 22 and which is configured to allow the discharge of the water outside the oven.
  • the piezoelectric aerosol generator 13 is so arranged and configured as to be able to transmit its own oscillatory strains as mechanical impulses to the water inside the atomization tank 12.
  • the transmission of the mechanical impulses preferably occurs through the direct contact (e.g., by dipping) of a vibrating plate 15, made of or connected to a piezoelectric crystal 14, with water.
  • such transmission of the vibrating plate 15 oscillation to the water can occur in an indirect manner, through a solid transmission means (a mechanical stirrer), or through a transmission fluid (an hydraulic or pneumatic stirrer).
  • a solid transmission means a mechanical stirrer
  • a transmission fluid an hydraulic or pneumatic stirrer
  • the aerosol generator 13 vibrating plate 15 is arranged just beneath and essentially parallel to the water level in the atomization tank 12.
