- the invention is particularly advantageously applicable to microwave cooking appliances.
- US 2004/0188429 A1 discloses a distributed microwave system that includes a single microwave source that can be used to power microwaves.
- the microwave source is located away from the devices and connected to them by a microwave line.
- US 2014/305933 A1 discloses a semiconductor microwave oven and associated microwave feed structure.
- the microwave feed structure includes a chamber body having a door, a semiconductor microwave power source, and a microwave feed assembly connected between the semiconductor power source and the chamber body and configured to feed the microwaves generated from the semiconductor power source into the chamber body and from EP 2 187 699 A1 discloses a cooking appliance comprising an interior space comprising at least one cooking cavity and comprising at least one cooking appliance A microwave guide structure for guiding microwaves from at least one microwave source to at least one opening in a wall or wall part of the interior space, wherein the microwave guide structure has an outer electrically conductive and fixed walling and at least one element for radiating the microwaves rowellen in the interior, the Mikrowellenleit Jardin comprises a first portion having a first cross-sectional shape of its outer electrically conductive Bewandung and a second portion having a second cross-sectional shape, the second
- Cross-sectional shape substantially round, in particular circular, and is different from the first differs in cross-sectional shape, and the element is disposed at the one end of the second portion in the interior.
- EP 2 187 701 A1 discloses a device for feeding microwaves into an interior of a cooking device, comprising: at least one resonator chamber, at least two antennas assigned to the resonator chamber, each having the radiation characteristic of a dipole antenna, in which substantially no microwave power is emitted along an antenna axis, and means for supplying microwaves of wavelength ⁇ to the antennas, wherein the two antennas emit substantially orthogonal polarized radiation, each antenna is mounted on a wall of the resonator cavity, and the antenna axes are oriented in substantially perpendicular directions, and a cooking appliance and a method for feeding microwaves into an interior of a cooking appliance.
- a cooking appliance having a cooking chamber and a microwave device for feeding microwaves into the cooking chamber, wherein the microwave device has a chamber arranged outside the cooking chamber (hereinafter referred to as "feed chamber” without restriction of generality) into the feed - Sung chamber protrudes a microwave line and the feed chamber opens by means of at least one opening in the cooking chamber.
- the microwave line is galvanically connected to an opening bounding, electrically conductive wall portion of the feed chamber.
- 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.
- the microwave line crosses at least one resonantly excitable emission opening. This enables achievement of a particularly high quality. 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 appliance can thus be partially double-layered on that cooking chamber wall to which the feed chamber is attached. One layer is the front wall of the feed chamber having the emission opening and another is a cooking chamber wall.
- the fact that the cooking chamber wall has an opening which is at least congruent to the emission opening may include that these two openings are exactly congruent (ie in particular the same, having superimposed edges) or that the opening of the cooking chamber wall is larger than the emission opening.
- 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.
- Both adjoining walls then carry correspondingly there a larger opening or recess, where the corresponding and geometrically determining resonantly excitable opening of the other wall opposite.
- an opening in the cooking chamber wall can be a resonantly excitable radiation opening if it can be galvanically connected to the microwave feed line.
- the feed chamber has a front wall which is formed by means of the cooking chamber wall and in which at least one resonantly excitable radiation opening is present.
- a feed chamber initially open to the cooking chamber wall is mounted, with the associated cooking chamber wall facing the cooking space after installation or to the cooking chamber
- Garraum adjacent wall or wall portion of the feed chamber is.
- the cooking chamber wall then represents the front wall of the housing of the feed chamber.
- at least one emission opening is closed with a microwave transparent material.
- at least one emission opening can be traversed or interrupted by in each case at least one web made of a material that is permeable to microwaves.
- Several webs of a radiation opening can be arranged for example in the form of a grid.
- an otherwise air-filled interior of the feed chamber is at least partially filled with an at least electrically insulating material.
- An at least electrically insulating material may be understood to be an electrically insulating material or an electrically and thermally insulating material. Possible materials with which the feed chamber can be filled include e.g. Glass wool or ceramic foam.
- a housing of the feed chamber has additional air passage openings which are not resonantly excitable and which are advantageously impermeable to microwaves.
- the air vents may allow for air cooling or, when placed in a fan duct, increase in pressure ("vented chamber"). By means of the pressure increase in the feed chamber also a Wraseneintrag from the cooking chamber can be reduced in the feed chamber or even avoided altogether.

- the microwave oven 1 has a - possibly also heatable - cooking chamber 2, which is bounded by a cooking chamber wall 3.
- a feed chamber 5 is fixed as a component of a microwave device.
- the feed chamber 5 has an inner space 7 surrounded by an electrically conductive housing 6.
- a slot-shaped emission opening 9 opening into the cooking chamber 2 is present in a front wall region (front wall 8) of the feed chamber 5.
- the front wall 8 is thus facing the cooking chamber 2 and lies flat on the side wall 4 of the cooking space wall 3.
- the side wall 4 also has an opening 10 which is larger than the emission opening 9 and this releases, so not covered.
- connection opening 12 In a wall section ("ceiling" 11) perpendicular to the front wall 8, a further opening (“connection opening” 12) is provided for connecting a microwave line.
- the microwave line is here designed as a microwave coaxial cable 13, 14, which is inserted into the connection opening 12.

- the inner conductor 13 is separated from the outer conductor 14 by a dielectric 13a, e.g. made of Teflon, separately.
- the inner conductor 14 is galvanically connected to a wall region of the feed chamber 5 delimiting the emission opening 9 by being in the vicinity of the emission opening 9 with the front wall 8, for example, by caulking, Verklinkung, Versch robbery, welding, etc. electrically connected.
- the inner conductor 14 starting from the connection opening 12, initially runs parallel to the front wall 8 and thereby traverses the emission opening 9. Subsequently, the inner conductor 14 bends at right angles in the direction of the front wall 8. The inner conductor 14 then abuts perpendicular to the front wall. 8
- the microwave coaxial cable 13, 14 is supplied with microwave MW, which is supplied by a microwave generator, e.g. a magnetron (not shown), as another component of the microwave device.

- the Abstrahlöff- 9 can also be considered as a slot antenna.
- the emission opening 9 does not emit microwaves in the interior space 7, but is fed directly by means of the internal conductor 14.
- the feed chamber 5 is not a microwave resonant chamber.
- a chamber height d can be kept particularly flat, as a result of which installation space can be significantly saved.

- the feed chamber 20 may be used with the microwave oven 1, for example.
- the feed chamber 20 differs from the feed chamber 5 in that the inner conductor 14 does not contact the front wall 8 of the housing 21 facing the cooking chamber 2, but rather a rear wall region (rear wall 22) facing away from the cooking chamber 2. Because the housing 21 is electrically conductive, and therefore the rear wall 22 over lateral wall area
- the ceiling 1 1 and a bottom 23 is electrically connected to the front 8
