Definitions

  • the invention relates to an electric cooking oven according to the first part of claim 1.
  • Such an electric cooking oven makes it possible to place generally, in the cooking chamber, a single dish of a food preparation. Indeed, given the construction of the rotary device, when user wishes to process several dishes, either different, or similar for several people, it must successively position the dish inside the oven, program the oven electric cooking and finally trigger the operation of said electric oven. This operation is therefore performed as many times as there are dishes to be processed, and therefore requires numerous manipulations of the user. On the other hand, in such devices of cooking, when the food to be cooked is placed in stacked containers or packaging with dimensions adjacent to the cooking chamber, these prevent a good distribution of microwaves thus causing different food treatments.
  • US-A-4,337,384 and US-A-4,481,396 each describe a microwave oven with two rotating trays of food reception.
  • the object of the invention is to remedy the aforementioned drawbacks when using an oven electric cooking for simultaneous processing several foods.
  • the new rotary receiving device in the enclosure of cooking, handling of dishes in the oven is greatly improved.
  • such a new device rotary receiver increases capacity traditional electric baking oven, namely the possibility of simultaneously processing several dishes thus limiting electricity consumption and increasing the speed of food preparation.
  • the judicious adaptation of the output in the cooking chamber improves, thanks to its correlation with said new rotary receiving device, the distribution of microwave energy within the enclosure cooking and therefore each of the food to be cooked placed on different levels within the enclosure of cooking undergoes optimum microwave radiation allowing to obtain a very good treatment of said food to cook.
  • 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, inter alia, 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, 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 promote good distribution of the waves on the two plates 9 and 10.
  • Said rotary tables are preferably circular.
  • the microwave energy source emits, by example, a radiation whose frequency is 2450 Mhz.
  • the enclosure of cooking comprises, for each of the rotary plates 9, 10, two guide means 11, 12; 13.14, of which only one 11; 13 of said two guide means is visible.
  • the upper 10 and lower 9 rotary tables are mounted respectively in rotation by any known means on removable supports 15, 16 resting respectively on the guide means.
  • Said supports 15, 16 include means of transmission 19 of the rotary movement interposed in coupling between the control means 23 and the turntable 9; 10.
  • the control means 23 (not shown in this figure) are arranged on one at less of the enclosure walls and have at least one electric motor group.
  • the upper rotary tables and lower having substantially similar dimensions dimensions of the cooking chamber, the two means guide 11, 12; 13, 14 are placed respectively on each of the side walls 7 and 8 of the enclosure of cooking, in order to easily position each of the trays rotary.
  • the two guide means 11, 12 of the lower plate 9 are placed close to the sole wall 6, and the two guide means 13, 14 of the upper plate 10 are placed substantially at mid-height in the cooking chamber.
  • the output of the waveguide 3 comprises at least two openings 30 and 32 (see figure 4 or 5), one of which 32 is arranged between the rotary plates 9; 10.
  • the output of the waveguide 3 comprises three openings 30, 31 and 32: A first opening 32 is located between the lower 9 and upper shelves 10; 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 plate upper 10 ( Figure 5). In the latter case, best results in wave distribution are obtained by arranging for most of the waves from the waveguide through the opening intermediate 31 enters the enclosure on one level located below the upper plate 10.
  • each of the rotary plates 9; 10 is rotatably mounted respectively on a removable support 15; 16 presenting the shape of a rectangular tray whose width and depth are virtually identical to the width and the depth of the interior of the cooking chamber.
  • Each of said removable supports 15; 16 includes a front part 17 and rear part 18, said part rear 18 being intended to come into abutment against the bottom wall 4 when said removable support 15; 16 is correctly positioned inside the enclosure cooking.
  • Each removable support 15; 16 consists of preferably a material transparent to microwaves such than plastic, and the turntable 9; 10 is from preferably made of tempered glass.
  • Such support removable 15; 16 includes transmission means 19 ( Figure 3) interposed in coupling between the means of control 23 and the turntable 9; 10.
  • Support removable is positioned, for example, on means of guide 11, 12; 13, 14 fixed on the side walls 7; 8 of the cooking chamber, and having in this realization of the form of longitudinal slide.
  • FIG. 3 in which the elements of the FIGS. 1 and 2 are designated by the same references, only the upper removable support 16 and the plate 10 are positioned in the cooking chamber.
  • the transmission means 19 of the removable support upper 16 include a shaft 20, one end of which 21 is fixed on the rear part 18 of the removable support 16 opposite the bottom wall 4 and the other of which end 22 is adapted to mate with the control means 23 comprising, inter alia, a motor electric not shown.
  • the control means 23 comprising, inter alia, a motor electric not shown.
  • 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 plateau 9, we can also consider another rotary table without sliding support, with control means in rotation then arranged under the sole 6 in a manner known in oneself.
  • the oven cooking is additionally provided with at least one resistance heater placed under the roof wall 5. Said resistance is moved away from an appropriate height upper turntable 10 so that the infrared radiation does not burn dishes placed on the plate 10.
  • the electric cooking oven thus constituted is of easy to use for the user and facilitates simultaneous processing of several dishes and dishes.
  • the user wishing to process several dishes or put position the different removable supports in the cooking chamber to the position shown on Figure 3.
  • the user places the containers containing the dishes to be cooked on each of the trays rotary placed in the cooking chamber.
  • Said user programs the electric oven according to the type foods constituting the dishes placed in said cooking chamber and trips, after checking the closing the oven door, the operation of said oven.
  • the user can position one and / or the other of the removable rotating trays in the cooking chamber so that you can process one or more foods.
  • the transmission means 19 fitted to the removable supports 15; 16 the establishment or the removal of these supports is simple and automatic, thus ensuring, on the one hand, ease of cleaning the cooking chamber and, on the other hand, a great convenience of using the oven for a family of users.
