20100270283 | COOKING OVEN FOR FOODS WITH VARIABLE SPEED ELECTRIC FAN AND DEVICE FOR REGULATING THE SPEED WITH HEAT RECOVERY - A cooking oven for foods is described, comprising a cooking chamber, a variable speed electric fan arranged for generating forced ventilation of the air inside the chamber, a regulating system for regulating the speed of the motor of the electric fan including at least one resistive electric element in the electrical supply circuit of the motor, in order to obtain the variation of the speed of the fan as a result of the electrical supply of the resistive element, wherein the resistive element is provided inside the cooking chamber of the oven, so that the heat generated by the resistive element is recovered and maintained within the cooking chamber in the thermal balance of the chamber, during the cooking of the foods. | 10-28-2010 |
20110202179 | METHOD FOR SPECIFYING CONTROL CURVE PARAMETERS FOR CONTROLLING CLIMATIC ENVIRONMENTAL CONDITIONS OF CLIMATE-CONTROLLED ENCLOSED SPACES - A method is provided for specifying the parameters of control curves of equipment for controlling the environmental conditions of climate-controlled enclosed spaces, including the step of specifying at least one control curve for the equipment, which is formed by a sequence of pairs of values introduced in succession. Each pair identifying the value of a predetermined parameter in a corresponding instant of time, the curve, indicating the desired variation of the parameter in time, is used for reproducing the variation of the parameter in time in said space according to the specified curve. The method also includes preliminary plotting of the shape of a curve in a graphic system of Cartesian axes. The curve represents a previously selected variation of the predetermined parameter as a function of time. | 08-18-2011 |
20110226229 | CLOSURE DEVICE ASSOCIABLE WITH AN OPENING OF A COOKING CHAMBER OF AN OVEN WITH A TROLLEY FOR THE SEALED CLOSURE OF THE CHAMBER IN THE ABSENCE OF THE TROLLEY - A closure device associable with the opening of the cooking chamber of an oven of the type with trolley is described, the oven including a closure door associated with the chamber, for the sealed closure of the cooking chamber in the absence of the trolley, the device includes a closure element capable of being placed to close a portion of the opening of the chamber that is not involved by the closure door, the portion of opening being capable of permitting the closure of the door when the trolley is inserted into the cooking chamber, the closure element co-operating in a sealed manner with respective sections of gaskets arranged at the opening, for the sealed closure of the cooking chamber when the trolley is not inserted in the chamber. | 09-22-2011 |
20110232624 | METHOD FOR CONTROLLING THE CONCENTRATION OF A COMPONENT OF A GASEOUS MIXTURE RECIRCULATED IN A COOKING CHAMBER, PARTICULARLY IN FOOD COOKING OVENS - A method is provided for controlling a gaseous component concentration of a gaseous mixture, which is recirculated by a ventilator in an oven, which is supplied with power at a predetermined mains frequency and voltage, the ventilator being driven by an asynchronous electric motor of known synchronism speed, the mixture being subjected to a known pressure. The method includes: detecting the temperature of the mixture in the cooking chamber, varying the motor's power supply voltage in order to maintain the motor's rotation speed at a predetermined value, measuring the difference between the mains voltage that supplies the motor and the motor's power supply voltage at the predetermined speed, using the voltage difference, the temperature and the known pressure to determine the component concentration in the mixture, comparing the component concentration which is found with a desired concentration value and, adjusting the component concentration in the cooking chamber. | 09-29-2011 |

20140356171 | ROTOR FOR A CENTRIFUGAL FAN, PARTICULARLY FOR THE FORCED CIRCULATION OF AIR IN CONVENTION COOKING OVENS - A centrifugal fan rotor includes radial blades extending from a disc support connectable to a hub for connection to the rotor's shaft. The blades are produced by stamping metal sheet, each having a corresponding blade surface and opposite attachment projection to the disc support. The rotor includes at least a first group of the blades in which each blade of the first group is provided with respective attachment projections upstream of the corresponding blade surface with respect to a direction of rotation of the rotor, and at least a second separate group of the plurality of blades in which each blade is provided with respective attachment projections arranged downstream of the corresponding blade surface with respect to rotation direction, such that each blade of the first and second groups are mirror-symmetrical to each other with respect to a radial center plane of symmetry between the blades extending through rotation axis. | 12-04-2014 |
