  • the at least one opening (hereinafter referred to as "radiation opening” without restriction of generality) is resonantly excitable by the microwaves.
  • the feed chamber is a non-resonant chamber for the microwaves.
  • This cooking appliance has the advantage that it can be carried out particularly compactly, since the feed chamber is a non-resonant chamber and therefore - in contrast to a resonator chamber - does not need to comply with dimensions for fulfilling resonance conditions of the microwaves.
  • this cooking appliance can be implemented robustly and in terms of manufacturing technology.
  • This cooking appliance makes use of the knowledge that the emission opening is directly resonantly excitable by means of the microwave energy supplied via the microwave feed line and then itself radiates microwave radiation into the cooking space ("self-resonating opening"). Since the opening vibrates resonantly and can radiate effectively into the oven, results in a good broadband results.
  • the resonantly excited emission opening can in this sense also be regarded as a microwave line supplied directly by the microwave feed line. Indirect connection or coupling via a microwave resonance excited in the chamber is not required.
  • the present feed chamber is only needed to turn the microwave feed line to a suitable one
  • the feed chamber can assume the function of a housing with electrical conduction in order to mechanically pick up or realize the at least one emission opening, but has no or only a slight influence on the quality.
  • the feed chamber therefore does not need to be designed for a high field excitation and field amplification and can, for example, be made particularly flat.
  • the properties of the emission aperture eg its intrinsic or resonant frequency
  • the low height of the feed chamber can be used in particular to arrange the feed chamber without a noticeable restriction of a volume of the cooking chamber on a wall of the cooking chamber. This also improves a positioning of the feed chamber.
  • the feed chamber can be arranged, for example, on a ceiling, on a floor, on left and right side walls, on a rear wall, etc. of the cooking chamber.
  • the cooking appliance is a household cooking appliance, in particular a kitchen appliance.
  • the cooking appliance may be a pure microwave oven ("microwave oven”).
  • microwave oven can be a combination of a heatable oven and a microwave oven, eg an oven with a microwave functionality. If the cooking appliance has such a furnace functionality, the cooking chamber can also be referred to as oven chamber become.
  • the cooking chamber typically has a front loading opening for loading the cooking chamber, which can be closed by means of a door.
  • the microwave device may comprise a microwave generating unit, e.g. a magnetron.
  • the microwave line is configured and arranged to direct microwaves or microwave energy generated by the microwave device to the opening bounding wall portion of the feed chamber.
  • the microwaves may have a frequency of 2.45 GHz.
  • the protruding into the feed chamber portion of the microwave line can radiate microwaves in the feed chamber and thus act as an antenna.
  • the wall region delimiting the emission opening or even the entire housing of the supply chamber is designed to be electrically conductive. This allows a particularly effective guiding effect for the microwaves.
  • a shield is thus provided for microwaves radiated from the microwave feed line into the feed chamber.
  • the wall opening bounding the radiating opening or the whole housing may be made of metal, e.g. made of sheet metal, in particular of sheet steel.
  • the at least one emission opening is slot-shaped ("self-resonating slot"). As a result, a particularly high feed-in efficiency is achieved.
  • the at least one emission opening can then also be regarded as a slot antenna, which however does not decouple microwaves from the feed-in chamber, but is supplied directly by means of the microwave feed line.
  • at least one resonantly excitable radiation opening is a curved opening, in particular a curved slot.
  • the curved emission opening is a U-shaped opening, in particular a U-shaped slot. This embodiment has the advantage that it is possible to reduce the dimensions of the emission opening.
  • at least one resonantly excitable emission opening is a rectilinear opening, in particular a rectilinear slot. This allows a particularly simple introduction and design.
  • the at least one emission opening has at least two emission openings. So a particularly high microwave power can be delivered into the oven. Also, a particularly good distribution of the propagating in the oven microwave can be achieved.
  • At least two radiating openings are separated from one another by a web and the microwave line makes galvanic contact with the web.
  • This arrangement allows particularly low losses and a particularly high quality, in particular in the sense of low reflection values S1 1.
  • This arrangement can also be understood as a single, divided by at least one ridge in each resonantly excitable partial emission openings Abstrahlö Anlagenen.
  • slit-like openings In the case of a plurality of slit-like openings, these may be arranged at arbitrary angles to each other, e.g. parallel or rotated by 90 °.
  • a twisted or non-parallel arrangement of the openings has the advantage that a mutual influence of the microwave feeds in the cooking chamber can be kept low, since then microwaves with different polarization are fed into the oven.
  • the microwave line is an inner conductor of a koaxialia len microwave line, in particular an inner conductor or center conductor of a microwave coaxial cable.
  • the coaxial microwave line has the advantage of inexpensive and robust conduction.
  • such an inner conductor can easily be galvanically fixed to a desired wall section, for example by caulking, latching, screw connection, welding, etc.
  • the inner conductor of the coaxial feed line can act as an antenna in the interior of the feed chamber.
  • the length of the inner conductor may vary depending on the shape and / or size of the feed chamber used. It is a development that the outer conductor or the shielding of the coaxial microwave line ends outside the interior of the feed chamber, so the outer conductor does not protrude into the chamber interior.
  • microwave line is a microwave coaxial cable
  • this can in particular be directly soldered, caulked, screwed, etc. ("semi-rigid").
  • the microwave line galvanically contacts a wall portion facing the cooking space, in particular near the emission opening.
  • a particularly small distance to the at least one opening can be achieved.

It is also an embodiment that the microwave line galvanically contacts a wall portion not facing the cooking chamber. This wall section may be one of the at least one opening facing away from the chamber wall. If a chamber wall facing the cooking chamber is referred to as a front wall, the remote chamber wall is a rear wall. The inner conductor can be bent so that it runs away from the radiation opening. A distance between these two chamber walls may also be referred to as a chamber height.
  • the microwave line tapers perpendicular to the wall area to be contacted. It is advantageous for a particularly space-saving arrangement in the cooking appliance when the microwave line, in particular the inner conductor, has a rectangular course in the feed chamber.
  • the housing of the feed chamber may have basically any shape, e.g. be rectangular, at least partially flattened or bevelled or rounded rounded.
  • the feed chamber has a front wall facing the cooking chamber, in which the at least one resonantly excitable radiation opening is introduced, the front wall rests on the outside of a cooking chamber wall and the Cooking chamber wall has at least one opening which is at least congruent to the emission opening of the feed chamber.
  • the feed chamber can be made particularly easy microwave-tight.

  • the cooking chamber wall thus does not cover the emission opening, so that microwaves can pass unhindered through the cooking space wall.
  • the emission opening in the feed chamber may be at least congruent with the opening in the cooking space wall.
  • there may be a U-shaped opening in the feed chamber while an opening in the form of a straight slot is realized in the cooking space wall.
