Definitions
- This invention relates to a microwave and forced convection or steam oven with gas or electric heating of the food disposed in the cooking chamber of the oven.
- Combined microwave and thermal ovens which cook the food contained in a plurality of pans arranged one atop the other inside the cooking chamber of the oven are also well-known (e.g. as claimed in the European patent No. 0068161, priority 20-6-1981).
- the magnetrons are mounted above the cooking chamber and the microwaves are directed toward the latter by one or more waveguides vertically disposed on the cooking chamber side walls thus cater-corner irradiating the pans through a plurality of spaced microwave slots.
- Fig. 1 and 2 showing a forced convection and microwave cooking oven utilized for community kitchens, it can be seen that it substantially consists of a metal casing 6 enclosing a cooking chamber 7 in which are housed some special shelves or pans 8 set one atop the other, on which the food to be cooked is placed, said shelves being inserted and removed in an advantageous way with respect to the side guides 9 of the cooking chamber 7, previous opening of the oven front door 10.
- Said cooking chamber 7 is subdivided into a further inner chamber 11 by a partition wall 12 extending along the entire height and part of the width of the cooking chamber, the latter being in communication with said inner chamber 11 by means of some side openings 14 and a central opening 15a provided on the partition wall 12 for the hot air circulation, the inner chamber 11 being provided with a centrally disposed fan 15 driven by a coaxial electric motor 16 mounted externally against the rear wall 17 of the oven.
- the fan 15 is laterally delimited by a group of tubular conduits 18 arranged close to its circumferencial edge, said tubular conduits 18 being properly bent so as to encircle said fan 15 and being connected with their upper and lower ends respectively with one or more discharging chimneys located on the upper part of the oven and with a not indicated combustion chamber placed in the lower part of the oven and housing at least a conventional gas burner.
- An electric heating as an alternative to the gas heating can be achieved by arranging suitable resistors, preferably circular resistors, around the periphery of the fan 15.
- the cooking oven can possibly be connected to an external steam generator as a boiler 20 or similar item, communicating through a duct 21 with the inner chamber 11 or even directly with the cooking chamber 7, with the purpose of determining the cooking of the food by means of metered quantities of steam introduced inside said cooking chamber, or by means of the combined action of steam and forced hot air circulation.
- an external steam generator as a boiler 20 or similar item, communicating through a duct 21 with the inner chamber 11 or even directly with the cooking chamber 7, with the purpose of determining the cooking of the food by means of metered quantities of steam introduced inside said cooking chamber, or by means of the combined action of steam and forced hot air circulation.
- the microwave heating is obtained by disposing externally and symmetrically to the cooking chamber 7 two magnetrons 22 and 23, said magnetrons being connected to said cooking chamber by two corresponding lateral and symmetric trumpets 24 and 25 which cover the respective magnetrons and have the triple aim of avoiding the escape of radiations to the exterior, of guiding the radiations toward the cooking chamber and of containing a special propagation mixing device 26, 27 well-known from the state of the art as a "stirrer".
- said clearance practically becomes a new and smaller cooking chamber contained in the original cooking chamber, the former being de-limited up and down respectively by the bottom of the upper pan and the bottom of the lower pan.
- the two magnetrons 22 and 23 are placed over but however externally to the side walls and in a central position with respect to said cooking chamber.
- the radiations emitted by said magnetrons is guided by two downwardly oriented, symmetrical and vertically disposed waveguides 50 and 51, substantially extending down to the bottom 52 of the cooking chamber, the walls 53 and 54 being facing the inside of the cooking chamber constituting an integral part of the respective walls 55 and 56 of said cooking chamber, so that the walls 53 and 54 are part both of the walls of the respective waveguides and of the corresponding cooking chamber walls.
- the walls 53 and 54 of said vertical waveguides 50 and 51 are provided with a series of substantially similar inclined slots 55, 56, 57, 58, 59 from which the microwaves propagate toward the interior of the cooking chamber, said slots being equally spaced one from the other in such a way that a slot terminates where the next one starts.
- FIG. 2c A further modification of the configuration of the slots from 55 to 59 is shown in Fig. 2c, where it can be seen that said slots, even if still inclined, are however parallelly disposed.
- the just described oven is fit to attain the wanted result of performing a microwave cooking programme in a cooking chamber housing a plurality of pans set one atop the other. Nevertheless, it still remains the problem consisting in the fact that it is not possible to superpose the pans without carrying out some other modifications.
- the pans are introduced into the cooking chamber 7 by fitting their borders onto horizontal metallic guides parallelly disposed at different heights on both side walls of said cooking chamber.
- the forced convection takes place by drawing the air from a central opening provided on the rear wall of the cooking chamber and by blowing this air, after it has been heated, into said cooking chamber, through a plurality of slots 14 made on the side walls of said chamber, preferably on the entire height of said walls, said slots being obtained in the free space between the pan supporting guides 9 as shown in Fig. 6. It is apparent that this type of structure is inconsistent with the direct utilization of this invention since the guides 9 and the air ducts present on the side walls would originate a very serious obstacle to the normal microwave propagation.
- a heat resisting and microwave-transparent material as for instance ceramic, polytetrafluoroethylene, polyether-etherketone, polysulfone or other material with similar characteristics can advantageously be used for producing said guides.
- a further improvement of this invention is the following: it is known that the microwave ovens must comply with the safety requirements set forth in the existing specifications and in particular to those specifications related to the emission of microwave radiations.
- said shaft extends backward outside the rear wall of the oven, as it is shown in Fig. 2, said shaft becomes, as far as the propagation is concerned, a transmitting antenna which propagates outside the oven, the radiation that it picked up inside the inner chamber 7, thus affecting the safety requirements.
- a toroidal choke 31 consisting of a fixed cylindrical part 32 (welded to the cell itself) and a rotating part 33, the latter being integral with the rotating element, which can be made of metal.
- the characteristic of said choke 31 is that its two component parts 32 and 33 resemble to two different sized small cups inversely inserted one into the other.
- the hollow space 31 forms a labyrinth for the microwave propagation and if the depth of said labyrinth exceeds a quarter of the wave length, then, as it is well-known, said labyrinth will act as an effective obstruction to the microwave propagation.
- the shaft 30 could act as a receiving antenna, the diameter of the fixed cylindrical part 32 should be smaller or equal to a quarter of the wavelength and its depth longer than said limits, as indicated in Fig. 9.
- a still further improvement of this invention can be achieved in the combined indirect gas heating and microwave ovens.
- the heat is obtained by burning the gas inside a closed chamber located, as a rule, underneath the fan, and is conveyed into the cooking chamber by means of a heat exchange between the burnt gas exhaust conduits and the air and steam current which, being made to circulate by the convection fan, comes in contact with said conduits.
- the latter are disposed, as a rule, at the sides of said fan (see Fig. 2) and, since the air inlets on the side of the cooking chamber are rather large, it comes out that the microwave propagation inside said cooking chamber penetrates into the back chamber where the fan and the conduits are located thus hitting them throughout.
- such an escape route can be blanked between said conduits and the wall which encircles them, said wall being in this case the upper cover of the oven; but the blanking operation, for instance the welding operation, besides being delicate and costly is not always possible since it may be necessary to maintain an air gap between said surfaces or because the concerned surfaces may require to be removable or independently expandable.
- said item 41 is substantially a gasket made of a very dense thin metal braided wire.
- This gasket is placed along the path 42 of the microwaves and in contact with the metallic surfaces 43 and 44, is capable of completely blocking the microwaves, allowing however a small gap for expansion between said surfaces.
- Another advantage of this item is due to the fact that it is extremely flexible and can fit or assume any shape without for this loosing its effectiveness. This type of item is currently available on the market under the commercial name of KNITEX.
