Abstract:
1. A method for specifying the parameters of control curves of equipment for controlling the environmental conditions of climate-controlled enclosed spaces, comprising: specifying at least one control curve for said equipment, said at least one curve being 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, said curve indicating the desired variation of the parameter in time, the control curve produced in this way being intended for a control unit of the equipment for operating corresponding devices for reproducing the variation of the parameter in time in said space according to the specified curve, plotting, using a plotter having manually controlled movement, of the shape of a curve in a graphic system of Cartesian axes, said curve representing a previously selected variation of the predetermined parameter as a function of time, processing the shape of said curve in a processing unit associated with the equipment, in order to identify a sequence of points belonging to the curve or correlated therewith, these points being positioned in succession, each point being identified by a pair of coordinates (value of parameter and time) relating to the system of Cartesian axes, said sequence reflecting the previously selected variation of the parameter in time along said curve, at predetermined time intervals, and transferring the resulting sequence of pairs of values to a control unit of the equipment, to operate corresponding devices of the equipment which are designed to reproduce the variation of said parameter in time in said enclosed space, wherein said enclosed space is a cooking chamber of an oven for food and the method further comprises specifying parameters of temperature, humidity, and the rotation speed of a fan in said chamber, according to corresponding curves of the variation of said parameters with time, the set of said curves reflecting a previously selected cooking cycle for a predetermined food item, the set of said curves can be stored in a storage medium and can be transferred from the medium to the control unit of the equipment and wherein a plurality of said sets of curves can be specified and stored, each set being characteristic of the cooking cycle of a corresponding food item, provision being made to associate an image of said food item with the corresponding set of curves to facilitate retrieval from a database which contains said plurality of curves.
