Definitions

  • the invention relates to a household cooking appliance with a cooking chamber and a microwave device for feeding microwaves into the cooking chamber, the microwave device having a feed chamber arranged outside the cooking chamber, a microwave line protruding into the feeding chamber and the feeding chamber opening into the cooking chamber by means of at least one opening .
  • the invention is particularly advantageously applicable to microwave cooking devices.
  • US 2004/0188429 A1 discloses a distributed microwave system that includes a single microwave source that can be used to power devices through microwaves.
  • the microwave source is remote from the devices and connected to them by a microwave line.
  • US 2014/305933 A1 discloses a semiconductor microwave oven and an associated microwave feed structure.
  • the microwave feed structure includes a chamber body with 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 by the semiconductor power source into the chamber body and from a first Convert microwave mode, which is output by the semiconductor power source, into a second microwave mode, which is adapted to microwave heating,
  • EP 2 187 699 A1 discloses a cooking device comprising an interior comprising at least one cooking space and comprising at least one 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, the microwave guide structure having an outer electrically conductive and solid covering and has at least one element for radiating the microwaves into the interior, the microwave guide structure comprises a first section with a first cross-sectional shape of its outer electrically conductive covering and a second section with a second cross-sectional shape, the second cross-sectional shape is essentially round, in particular circular, and is from the first Cross-sectional shape differs, and the element is arranged at one end of the second section in the interior.
  • EP 2 187 701 A1 discloses a device for feeding microwaves into an interior of a cooking appliance, comprising: at least one resonator chamber, at least two antennas assigned to the resonator chamber, each with the radiation characteristic of a dipole antenna, in which essentially no microwave power is emitted along an antenna axis, and means for supplying Microwaves of wavelength ⁇ to the antennas, wherein the two antennas emit polarized radiation essentially orthogonally to one another, each antenna is attached to a wall of the resonator chamber, and the antenna axes are aligned in essentially perpendicular directions, and a cooking device and a method for Microwaves are fed into an interior of a cooking appliance.
  • the object is achieved by a cooking device with a cooking chamber and a microwave device for feeding microwaves into the cooking chamber, the microwave device having a chamber arranged outside the cooking chamber (hereinafter referred to as "feed chamber” without restricting generality) and a microwave line into the feed chamber protrudes and the feed chamber opens into the cooking space by means of at least one opening.
  • the microwave line is galvanically connected to an electrically conductive wall area of the feed chamber that delimits the opening.
  • the at least one opening (hereinafter referred to as "radiation opening” without restricting generality) can be resonantly excited by the microwaves.
  • the feed chamber is a chamber that is not resonant for the microwaves.
  • This cooking appliance has the advantage that it can be made particularly compact, since the feed chamber is a non-resonant chamber and therefore - in contrast to a resonator chamber - does not have to comply with any dimensions to meet the resonance conditions of the microwaves.
  • this cooking device can be implemented robustly and easily in terms of production technology.
  • This cooking device makes use of the knowledge that the radiation opening can be directly resonantly excited by means of the microwave energy supplied via the microwave feed line and then itself emits microwave radiation into the cooking space ("self-resonating opening"). Since the opening vibrates resonantly and can radiate effectively into the cooking space, there is a good broad band. In this sense, the resonantly excited radiation opening can also be regarded as a microwave line supplied directly by the microwave feed line. An indirect connection or coupling via a microwave resonance excited in the chamber is not required. The present feed chamber is only required to guide the microwave feed to a suitable wall area of the feed chamber.
  • the feed chamber can in particular take on the function of a housing with electrical conductivity in order to mechanically accommodate or implement the at least one radiation opening, but has no or only a slight influence on the quality.
  • the feed chamber therefore does not have to be designed for high field excitation and field amplification and can e.g. be designed particularly flat.
  • the properties of the radiation opening e.g. its natural or resonant frequency
  • the low overall height of the feed chamber can in particular be used to arrange the feed chamber on a wall of the cooking chamber without a noticeable restriction in the volume of the cooking chamber. This also improves the positionability of the feed chamber.
  • the feed chamber can e.g. on a ceiling, on a floor, on left and right side walls, on a rear wall etc. of the cooking space.
  • the cooking device is a household cooking device, in particular a kitchen device.
  • the cooking device can be a pure microwave device (“microwave oven”).
  • microwave oven can be a combination of a heatable oven and a microwave device, for example an oven with a microwave functionality. If the cooking appliance has such an oven functionality, the cooking space can also be referred to as an oven space become.
  • the cooking space typically has a front loading opening for loading the cooking space, 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 designed and arranged to conduct microwaves or microwave energy generated by the microwave device to the wall region of the feed chamber that delimits the opening.
  • the microwaves can have a frequency of 2.45 GHz.
  • the part of the microwave line protruding into the feed chamber can emit microwaves into the feed chamber and thus also act as an antenna.
  • the wall area delimiting the radiation opening or even the entire housing of the feed chamber is designed to be electrically conductive. This enables a particularly effective conductivity for the microwaves.
  • a shield is provided for microwaves emitted by the microwave feed line into the feed chamber.
  • the wall area delimiting the radiation opening or the entire housing can be made of metal, e.g. made of sheet metal, in particular sheet steel.
  • the feed chamber is attached to the housing by welding, screwing, toxing (tox-clinching) etc.
  • the at least one radiation opening is designed in the form of a slot (“self-resonating slot”). This results in a particularly high feed-in effectiveness.
  • the at least one radiation opening can then also be viewed as a slot antenna, which, however, does not couple out microwaves from the feed chamber, but is supplied directly by means of the microwave feed line.
  • At least one resonance excitable radiation opening is a curved opening, in particular a curved slot. It is a further development that the curved radiation opening is a U-shaped opening, in particular a U-shaped slot. This configuration has the advantage that the dimensions of the radiation opening can be reduced.
  • At least one resonance excitable radiation opening is a rectilinear opening, in particular a rectilinear slot. This enables particularly easy insertion and layout.
  • the at least one radiation opening has at least two radiation openings. This enables a particularly high microwave output to be emitted into the cooking space. A particularly good distribution of the microwaves propagating in the cooking space can also be achieved in this way.
  • At least two radiation openings are separated from one another by a web and the microwave line makes galvanic contact with the web.
  • This arrangement enables particularly low losses and a particularly high quality, in particular in the sense of low reflection values S11.
  • This arrangement can also be understood as a single radiation opening, which is subdivided into at least one web into resonance excitable partial radiation openings.
  • slot-like openings In the case of several slot-like openings, these can be arranged at any angle to one another, e.g. parallel or rotated by 90 °.
  • a twisted or non-parallel arrangement of the openings results in the advantage that a mutual influence of the microwave feeds into the cooking space can be kept low, since microwaves with different polarization are then fed into the cooking space.
  • the microwave line is an inner conductor of a coaxial microwave line, in particular an inner conductor or center conductor of a microwave coaxial cable.
  • the coaxial microwave line has the advantage of an inexpensive and robust line.
  • such an inner conductor can simply be attached galvanically to a desired wall section, for example by caulking, latching, screwing, 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 can 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, that is, the outer conductor does not protrude into the interior of the chamber.
  • microwave line is a microwave coaxial cable
  • this can in particular be directly soldered, caulked, screwed, etc. ("semi-rigid").
  • the microwave line makes galvanic contact with a wall section facing the cooking chamber, in particular near the radiation opening. A particularly small distance from the at least one opening can thus be achieved.
  • the microwave line crosses at least one resonance excitable radiation opening. This enables a particularly high quality to be achieved.
  • the microwave line makes galvanic contact with a wall section not facing the cooking space.
  • This wall section can be a chamber wall facing away from the at least one opening. If a chamber wall facing the cooking chamber is referred to as the front wall, the chamber wall facing away represents a rear wall.
  • the inner conductor can be curved in such a way that it runs away from the radiation opening. A distance between these two chamber walls can also be referred to as a chamber height.
  • the microwave line runs perpendicularly to the wall area to be contacted.
  • the microwave line in particular the inner conductor, has a rectangular shape in the feed chamber.
  • the housing of the feed chamber can have any shape, e.g. rectangular, at least partially flattened or beveled or 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 on a cooking chamber wall, and the Cooking chamber wall has at least one opening which is at least congruent with the radiation opening of the feed chamber.
  • the feed chamber can be made particularly microwave-tight in this way.
  • the cooking appliance can therefore be constructed in two layers on the cooking chamber wall to which the feed chamber is attached. One layer represents the front wall of the feed chamber with the radiation opening and another layer represents a cooking chamber wall.
  • the fact that the cooking chamber wall has an opening that is at least congruent with the radiation opening can include that these two openings are exactly congruent (in particular, identical, superimposed edges has) or that the opening of the cooking space wall is larger than the radiation opening.
  • the cooking space wall therefore does not cover the radiation opening, so that microwaves can pass through the cooking space wall unhindered.
  • the radiation opening in the feed chamber can be at least congruent with the opening in the cooking chamber wall.
  • Mixed forms can also be implemented if there are several openings. For example, there may be a U-shaped opening in the feed chamber, while an opening in the form of a straight slot is implemented in the cooking space wall. Both adjoining walls then accordingly have a larger opening or cutout where the corresponding and geometrically determining resonant excitable opening is opposite the other wall.
  • an opening in the cooking space wall can also 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 there is at least one resonantly excitable radiation opening.
  • a feed chamber that is initially open towards the cooking chamber wall is installed here, the associated cooking chamber wall being the only wall or wall region of the feeding chamber facing the cooking chamber or bordering the cooking chamber.
  • the cooking chamber wall then represents the front wall of the housing of the feed chamber.
  • at least one radiation opening is closed with a microwave-permeable material. This can advantageously prevent the ingress of dirt coming from the cooking space.
  • At least one radiation opening can also be crossed or interrupted by at least one web made of a microwave-permeable material. 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 can be understood to mean 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 cannot be excited resonantly and which are advantageously impermeable to microwaves.
  • the air outlet openings can enable air cooling or, if arranged in the direction of a blower duct, achieve a pressure increase (“ventilated chamber”). By increasing the pressure in the feed chamber, an entry of vapors from the cooking space into the feed chamber can also be reduced or even avoided entirely.
  • Fig. 1 shows a sectional side view of a section of a household cooking device in the form of a microwave device 1.
  • the microwave device 1 has a — possibly also heatable — cooking space 2, which is delimited by a cooking space wall 3.
  • a feed chamber 5 is attached as a component of a microwave device.
  • the feed chamber 5 has an interior space 7 surrounded by an electrically conductive housing 6.
  • a front wall area (front wall 8) of the feed chamber 5 there is a slot-shaped radiation opening 9 opening into the cooking space 2.
  • the front wall 8 thus faces the cooking space 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 radiation opening 9 and exposes it, that is to say not covers it.
  • connection opening 12 for connecting a microwave line is provided in a wall section (“ceiling” 11) that adjoins the front wall 8 and is perpendicular thereto.
  • the microwave line is designed here as a microwave coaxial cable 13, 14 which is inserted into the connection opening 12.
  • An outer conductor 13 remains in the connection opening 12 and is galvanically connected to it or the ceiling 11, while an inner conductor 14 projects into the feed chamber 5 or into the associated interior space 7.
  • the inner conductor 13 is separated from the outer conductor 14 by a dielectric 13a, e.g. made of Teflon, separated.
  • the inner conductor 14 is galvanically connected to a wall region of the feed chamber 5 delimiting the radiation opening 9 by being in the vicinity of the radiation opening 9 is electrically connected to the front wall 8, for example by caulking, latching, screwing, welding, etc.
  • the inner conductor 14 Starting from the connection opening 12, the inner conductor 14 initially runs parallel to the front wall 8 and thereby crosses the radiation opening 9. The inner conductor 14 then bends at a right angle in the direction of the front wall 8. The inner conductor 14 then abuts the front wall 8 perpendicularly.
  • the microwave coaxial cable 13, 14 can be supplied with microwaves MW, which are generated by a microwave generator, e.g. a magnetron (not shown), as a further component of the microwave device.
  • the microwaves MW are conducted from the inner conductor 14 to the front wall 8 and cause the radiation opening 9 to be resonantly excited or to resonate. Consequently, the radiation opening 9 radiates microwaves with high quality into the cooking space.
  • the radiation opening 9 can also be regarded as a slot antenna.
  • the radiation opening 9 does not couple out microwaves standing in the interior 7, but is fed directly by means of the inner conductor 14.
  • the feed chamber 5 is not a chamber resonant for the microwaves.
  • a chamber height d can be kept particularly flat, which noticeably saves installation space.
  • Fig. 2 shows a sectional side view of an infeed chamber 15, for example for use with the microwave device 1.
  • the infeed chamber 15 is constructed similarly to the infeed chamber 5, but has no front wall area different from an electrically conductive side wall 16 of the cooking space wall 3. Rather, the side wall 16 of the cooking space wall 3 represents the front wall 8 of the feed chamber 15.
  • the radiation opening 9 is located in the side wall 16.
  • the feed chamber 15 can be placed on the side wall 16 during assembly, for example with an initially open front side.
  • the radiation opening 9 can be closed with a microwave-permeable material, e.g. with a microwave-permeable plate 17 or film.

  • the feed chamber 20 can be used with the microwave device 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.
  • the housing 21 is electrically conductive, and therefore the rear wall 22 is electrically connected to the front side 8 via the side wall area (not shown), the ceiling 11 and a floor 23, the inner conductor 14 continues to be the one that delimits the radiation opening 9 , electrically conductive wall area (namely the front wall 8) of the feed chamber 20 is galvanically connected.
