Definitions

  • the present invention relates to an electric oven with at least one microwave energy source to deliver waves to a cooking chamber microwave, by means of a waveguide.
  • a generally encountered problem in cooking in microwave mode lies in obtaining a good distribution of microwave energy within the enclosure cooking. Indeed, it is known that a standing wave regime settles in the cooking chamber for operation of the oven. As a result, the fields electric modes excited in the enclosure present bellies and knots of tension to which correspond so-called hot spots and points so-called cold at different places in the enclosure.
  • a first type of solution consists in providing, in the cooking chamber, a wave agitator so constantly changing the standing wave regime established in the enclosure, and thus move the hot spots and cold spots.
  • Another method widely used today current consists of placing the product to be heated or cook on a turntable. The relative displacement of the product and hot spots allows to standardize the cooking.
  • FIGS 1 and 2 schematically illustrate the internal parts of a known oven operating according to this principle: in these figures, there is shown a cooking chamber 1 delimited by a bottom wall 10, a vault wall 11, a hearth wall 12 and two side walls 13 and 14.
  • the side wall 13 has two horizontal openings 130 and 131 superimposed along the vertical of the wall 13, for the introduction of microwave energy.
  • the waves are generated by the antenna of a magnetron (not shown), and transmitted to the cooking enclosure via a wave guide 2.
  • the wave guide 2 has the general form of a rectangular parallelepiped whose longitudinal axis is vertical.
  • the guide is delimited transversely by two rectangular flat surfaces 20 and 21, perpendicular to the longitudinal axis of the guide and separated by a predetermined distance d defining the length 1 of the guide. These two surfaces define reference planes on which the guided waves are reflected.
  • the two surfaces 20 and 21 are interconnected at a right angle by two rectangular surfaces 22, 23, parallel to the side wall 13, each surface having two edges b 1 , b 2 , b 3 , b 4 of length d.
  • the surface 22 furthest from the side wall 13 has a lateral extension 24 provided with an access 25 for receiving the waves generated by the antenna of the magnetron.
  • the surface 23 constitutes the outlet plane of the guided waves and for this purpose comprises two openings 230 and 231 placed opposite the openings 130 and 131.
  • the outlet plane of the waveguide is directly constituted by a part of the side wall of the enclosure.
  • the present invention relates to an improvement to the structure as described above, allowing to obtain a better distribution of energy inside of the cooking chamber.
  • the subject of the present invention is an electric cooking oven comprising an enclosure , a microwave energy source and a guide of waves of substantially parallelepipedal shape delimited transversely by two substantially rectangular surfaces located in two parallel planes separated by predefined distance, leaving guided waves by at least two zones located in a plane of outlet perpendicular to the two surfaces and delimited by two parallel borders connecting the two surfaces, characterized in that said borders have a length greater than the distance between the two surfaces, so as to optimize the number of transverse electric modes and / or magnetic excited inside the enclosure cooking in parallel excitation planes to the exit plan.
  • the waveguide 2 ′ is of substantially parallelepipedal shape delimited transversely by two surfaces 20 ′, 21 ′ of substantially rectangular shape, and longitudinally by two surfaces 22 'and 23' forming, like the surfaces 22 and 23 of Figure 1, the inlet and outlet surfaces of the waveguide.
  • the borders b ' 1 , b' 4 and b ' 2 , b' 3 respectively delimiting the entry planes 23 'and outlet 22' of the guide, by connecting the surfaces 20 'and 21', have a length 1 greater than the distance d separating said surfaces 20 ', 21'.
  • the waveguide 2 ′ therefore no longer has the shape of a straight parallelepiped, but of an oblique parallelepiped whose longitudinal axis, parallel to said edges, is inclined relative to an axis orthogonal to the end surfaces 20 'and 21'. It follows that, for the same distance d separating the two surfaces 20 ′ and 21 ′, the waveguide 2 ′ according to the invention has a length 1 greater than that of the waveguide 2 in FIG. 1, this which will optimize, as will now be explained, the number of transverse electric and / or magnetic modes excited inside the cooking chamber 1, in excitation planes parallel to the outlet plane 23 'of the guide.
  • the exit zones of the guide are distributed over the height.
  • a mode of the enclosure located in the excitation planes parallel to the exit plane must have one of its tension bellies facing an exit zone of the waveguide. Consequently, all the modes of the form TE m0p or TM m0p which do not have bellies on the height, cannot be excited.
  • the modes whose central frequency is too far from the 2450 MHz frequency will be very weakly coupled.
  • the ultimately dominant modes, which should be excited are the modes TE 033 , TE 215 , TM 215 , TE 232 , TM 232 , TE 422 , TM 422 .
  • FIGS. 5a and 5b make it possible to establish a comparison between the number of transverse electrical and / or magnetic modes excited using respectively a waveguide structure of the prior art and a waveguide structure according to the present invention .
  • the reference P indicates an excitation plane of the modes parallel to the plane of exit of the waveguides. This excitation plane has the same dimensions as the side wall 13 of the cooking enclosure.
  • the position of the tension bellies has been indicated for the various transverse electrical modes which should be excited. These positions are indicated by dots for TE 033 mode, by crosses for TE 232 mode, by rectangles for TE 422 mode and by diamonds for TE 215 mode.
  • the outlet plane 23 'of the waveguide according to the invention is delimited by two edges b' 1 and b ' 4 connecting the surfaces 20' and 21 'over a length 1 greater than the distance d separating both surfaces.
  • the oblong openings 230, 231 and 232 have a longitudinal axis extending in parallel at the end surfaces 20 ′ and 21 ′ of the guide.
  • a wave which leaves the magnetron antenna does not travel the same distance to reach either end from the same opening. This results in a difference phase between the ends of an opening.
  • Non-consistency in phase of the waves at the ends of an opening has the consequence that the electric field radiated towards the enclosure through this opening is not maximum.
  • the oblong openings are tilted 230 to 232 with respect to a transverse axis of the plane of outlet 23 'parallel to the end surfaces 20' and 21 ', so as to reduce the difference in distance to cover for a wave from the antenna to both ends from the same opening.
  • the coherence of the incident wave the opening is improved, as is the radiated power. Consistency is perfect in the case where the openings are inclined so as to present a longitudinal axis orthogonal to the longitudinal axis of the guide.
  • the angle of inclination will be chosen in an angular sector delimited by a transverse axis from plane 23 ', parallel to surfaces 20', 21 ', and by a transverse axis of the plane 23 ', perpendicular to the longitudinal axis of the guide.
  • the voltage U evolves like a sinusoid arch along the length of the opening.
  • the width a is constant over the entire length of the opening. Consequently, according to equation (1), the radiated field E F follows exactly the same law as the voltage.
  • the width a is almost zero at the ends of the opening and increases towards the center.
  • the field E F remains substantially constant over the length of the opening. The radiated energy is therefore greater in the case of an elliptical opening.
  • a waveguide structure conforming to the present invention and particularly suitable for a electric oven capable of receiving products at heat on two separate levels, one lower level corresponding for example substantially to the level of the oven floor, and a corresponding higher level for example halfway up the cooking chamber.
  • the plane of outlet 23 'of the waveguide is directly in the wall side 13 of the cooking chamber, so that the figure 7 illustrates only the boundaries of the plan of outlet 23 'relative to openings 230, 231 and 232.
  • the guide surfaces 20 ′ and 21 ′ are spaced apart by a distance d substantially equal to 165 mm, while the edges b ′ 2 , b ′ 3 or b ′ 4 , b ′ 1 , separated by a distance substantially equal to 86 mm, have a length 1 of approximately 178 mm.
  • the longitudinal axis of the guide is therefore inclined about 22 degrees relative to the vertical.
  • the center of the opening 25 for the entry of the waves into the guide is located substantially at a distance of 94.5 mm, in orthogonal projection, from the end surface 20 '.
  • the opening 25 has a circular section with a diameter substantially equal to 30.6 mm.
  • the distance from the outlet plane 23 'to the inlet plane 22' is approximately 21 mm.
  • the distance from the outlet plane 23 'to the end of the extension 24 is approximately 41 mm.
  • the previous dimensions allow obtaining a non-resonant waveguide.
  • the waves exit takes place at three elliptical openings 230 to 232 ( Figure 7).
  • the intermediate opening 232 is advantageously located near the upper cooking level. In this way, the intermediate opening 232 makes it possible to create, on the one hand with the upper opening 230 and on the other hand with the lower opening 231, two interference zones that are fairly well uncorrelated from each other. , and therefore less sensitive to the charges placed on each of the two cooking levels.
  • the longitudinal axis of the openings 230 to 232 is for example inclined 11.5 degrees relative to an axis transverse to the outlet plane 23 'and parallel to the surfaces 20' and 21 '. This choice makes it possible to obtain a good compromise between a good restored power and a good temperature balancing on the two plates.
  • the height positioning of the openings is preferably also chosen as a function of the position of the tension bellies of the modes of the form TE mnp or TM mnp , the integer n, corresponding to the oscillations over the height, being equal to 1.2 or 3.
  • openings 230, 231 and 232 shown in Figure 7 have sizes different. This advantageously makes it possible to maximize the total power restored while respecting the constraints impedance matching.
