A combined apparatus for heating, cooking, grilling and defrosting of food of various kinds, depending on the kinds of food to be treated from time to time and the duration of the food treatment, comprising:
- a substantially box-like covering and containing envelope made of metal or also of other solid material and with parallelepiped shape, or other geometrical shape, in the lower part of which there are mounted some supporting feet, which is adjusted or not adjusted in height, and suitable for being laid and/or installed on to supporting surfaces of various types the apparatus further comprising an upper cover, hinged to the box-like envelope near its upper and back end portion and which is actuated either manually from the front part of the same envelope, or with an automatic opening at the end of food cooking, and displaceable from a lowered closed position in which the cover is aligned in a horizontal direction with a remaining upper surface of the envelope, and an interior of the envelope cannot be accessible from the outside, to a raised opened position thereof in which the cover is upset upward and arranged in a vertical position thereof almost orthogonal with respect to a remaining upper surface of the envelope and the interior of the envelope is accessible from the outside, the apparatus also comprising at least a control board for controlling carrying out of the different operative programs desired and selected by selector means, depending on the type and the quantity of food to be hot treated, and for regulating the power, the temperatures and the times of the desired treatments, said control board being connected to the apparatus electric circuits, together with heating element of food and temperature detecting means for heating said heating element, the envelope also comprising at least an inner room for the hot treatment of food, for introducing the food to be hot treated, which is accessible or not accessible by closing or opening said upper cover, said inner room being insulated thermally and adapted to be heated singularly either through said heating element or microwave generating means, or the combined action of said heating element and said microwaves generating means, said heating elements being included into at least a first movable lower heating plate or into at least a second stationary upper plate, and said upper cover being formed by a first flat cover portion and by a second flat cover portion, joined to the first cover portion at its front end portion, which is folded orthogonally frontwards with respect to such flat portion, and this second cover portion is made with a smaller surface with respect to the surface of said first cover portion, the upper cover being made with an external wall and an inner wall enclosing an insulating material, such as any insulation withstanding the high temperatures, said upper cover being also dimensioned in a manner that into its lowered position said first cover portion adapted on to the entire horizontal upper edge of said inner room (11), wherein said first heating plate is actuated by powered transmission means, controlled by said control board into different adjustment positions in height, depending on the size and the type of food to be hot treated, for enclosing the food between said two heating plates, said upper heating plate co-operating with weighing means connected operatively with said control board for detecting the weight of food disposed on to said first heating plate and providing for through the same control board the carrying out of each operative program respectively selected and the heating duration of each food, depending on the type and the weight of the food to be treated, and further comprising means for collecting the greases and the liquids produced during each hot treatment step of the food, and for disposing of the same during and after the hot treatment of such food.
