Definitions
- the invention relates to an electric cooking oven comprising a microwave energy source, a waveguide, the outlet of which opens into a cooking enclosure delimited by a bottom wall, a vault wall, a hearth wall and two side walls and a rotary device internal to the cooking chamber, intended to receive food to be cooked and driven in rotation by control means placed outside the cooking chamber.
- Such an electric cooking oven generally allows a single dish of a food preparation to be placed in the cooking chamber. Indeed, given the construction of the rotary device, when a user wishes to process several dishes, either different or similar for several people, he must successively position the dish inside the cooking chamber, program said electric cooking oven and, finally, trigger the operation of said electric oven. This operation is therefore carried out as many times as there are dishes to be treated, and therefore requires numerous manipulations by the user. On the other hand, in such cooking appliances, when the food to be cooked is placed in superimposed containers or packaging and with dimensions similar to the cooking enclosure, the latter prevent a good distribution of the microwaves thus causing treatments. different from food.
- the rotary device comprises at least two rotary plates, called lower and upper, removably mounted in the cooking chamber, superimposed and spaced from one another by a distance d and the outlet of the guide d 'waves is adapted to promote a good distribution of waves on the two plates.
- the handling of dishes in the oven is greatly improved.
- such a new rotary receiving device increases the traditional capacities of the electric cooking oven, namely the possibility of simultaneously processing several dishes thus limiting the consumption of electricity and increasing the speed of preparation of dishes.
- the judicious adaptation of the outlet in the cooking chamber improves, thanks to its correlation with said new rotary receiving device, the distribution of microwave energy in the cooking chamber and, by Consequently, each of the foods to be cooked placed at different levels in the cooking chamber undergoes optimum microwave radiation allowing very good treatment of said food to be cooked.
- Figure l shows, schematically in perspective, a cooking chamber of an electric oven according to the invention equipped with a first rotary receiving device.
- Figure 2 shows schematically in perspective on a reduced scale another embodiment of an electric cooking oven according to the invention, and equipped with a second rotary device;
- FIG. 3 is a vertical section, on a slightly enlarged scale, along the line I.I of Figure 2, but in which the rotary device is partially shown;
- FIGS. 4 and 5 are sectional front views of the oven cavity and the waveguide according to two possible embodiments of the invention.
- the electric cooking oven comprises, inter alia, a microwave energy source 2 such as for example a magnetron, a waveguide 3, the outlet of which opens into a cooking enclosure delimited by a wall bottom 4, a roof wall 5, a floor wall 6, two side walls 7 and 8 and a door not shown.
- the microwave energy source 2 and the waveguide 3 are fixed to the side wall 8.
- the cooking enclosure has, for example, the shape of a parallelogram, but any other geometric shape is possible.
- the electric cooking oven comprises, among other things, a rotary device R intended to receive dishes or food to be cooked and driven by control means 23 (fig. 3) placed outside the cooking enclosure, to preferably behind the back wall 4.
- the rotary device R comprises at least two rotary plates 9, 10, called lower 9 and upper 10, removably mounted in the cooking chamber, superimposed and spaced from each other by a distance d , and the output of the waveguide 3 is adapted to favor a good distribution of the waves on the two plates 9 and 10.
- Said rotary plates are preferably circular.
- the microwave energy source emits, for example, radiation with a frequency of 2450 MHz.
- the cooking enclosure comprises, for each of the rotary plates 9,
- the upper 10 and lower 9 rotary plates are mounted respectively in rotation by any known means on removable supports 15, 16 resting respectively on the guide means. Said supports 15, 16 comprise means 19 for transmitting the rotary movement interposed in coupling between the control means 23 and the rotary plate 9; 10.
- the control means 23 (not shown in this figure) are arranged on at least one of the walls of the enclosure and comprise at least one electric motor group.
- the upper and lower rotary plates having dimensions substantially close to the dimensions of the cooking enclosure, the two guide means 11, 12; 13, 14 are placed respectively on each of the side walls 7 and 8 of the cooking chamber, in order to easily position each of the rotary plates. As can be seen, the two guide means
- the outlet of the waveguide 3 comprises at least two openings 30 and 32 (see FIG. 4 or 5), one of which 32 is arranged between the rotary plates 9; 10.
- the outlet of the waveguide 3 comprises three openings 30, 31 and 32: A first opening 32 is located between the lower 9 and upper plates
- a second opening 30 is located above the upper plate 10; finally, an intermediate opening 31 is located either below the upper plate 10 (Figure 4), or substantially at the level of this upper plate 10 ( Figure 5). In the latter case, better results in the distribution of the waves are obtained by arranging for most of the waves from the waveguide through the intermediate opening 31 to enter the enclosure at a level below. of the upper plate 10.
- each of the rotary plates 9; 10 is mounted in rotation respectively on a removable support 15; 16 having the shape of a rectangular tray whose width and depth are practically identical to the width and depth of the interior of the cooking chamber.
- Each of said removable supports 15; 16 comprises a front part 17 and a rear part 18, said rear part 18 being intended to come into abutment against the bottom wall 4 when said removable support 15; 16 is correctly positioned inside the cooking chamber.
- Each removable support 15; 16 is preferably made of a material transparent to microwaves such as plastic, and the turntable 9; 10 is preferably made of tempered glass.
- Such a removable support 15; 16 comprises transmission means 19 (Figure 3) interposed in coupling between the control means 23 and the turntable 9; 10.
- the removable support is positioned, for example, on guide means 11, 12; 13, 14 fixed on the side walls 7; 8 of the cooking chamber, and having in this embodiment the form of longitudinal slide.
- the transmission means 19 of the upper removable support 16 comprise a shaft 20, one end 21 of which is fixed to the rear part 18 of the removable support 16 opposite the bottom wall 4 and the other end 22 of which is adapted to come coupling with the control means 23 comprising, inter alia, an electric motor not shown.
- the shaft 20 passes through a hole 24 made in the bottom wall 4, which facilitates connection with the control means 23.
- control means 23 and the transmission means 19 for the removable support 15 and the plate 9 are of a construction similar to that described above. However, for this lower plate 9, one can also consider another rotary plate without sliding support, with a rotation control means then arranged under the floor 6 in a manner known per se.
- the cooking chamber is further provided with at least one heating resistor placed under the roof wall 5. Said resistor is moved away from a height of the upper rotary table 10 so that the infrared radiation does not burn the dishes placed on the table 10.
- the electric cooking oven thus constituted is easy to use for the user and facilitates the simultaneous processing of several dishes and dishes.
- the user wishing to treat several dishes or dishes positions the various removable supports in the cooking chamber up to the position shown in FIG. 3.
- the user places the containers containing the dishes to be cooked on each of the rotary plates placed in the cooking chamber.
- Said user programs the electric oven according to the nature of the food constituting the dishes placed in said cooking chamber and triggers, after having checked the closing of the door of the cooking chamber, the operation of said oven.
- the user can position one and / or the other of the removable rotary trays in 1 • cooking enclosure so as to be able to process one or more foods.
