Definitions

  • a cooking appliance with a microwave generating device is, for example, in the non-prepublished EP 05026912.5 described.
  • a coaxial or strip conductor for transporting microwaves in an accessory can be integrated within a cooking chamber and provided with a contact and / or coupling device in order to be connectable to a microwave generating device arranged outside the cooking chamber.
  • the contact and / or coupling device can be electrically and / or magnetically shielded, vapor-tight and / or stable up to a temperature of at least 250 ° and comprise a plug connection. Further details of this connector are not described.
  • the present invention is therefore based on the object to further develop the generic microwave connector such that it overcomes the disadvantages of the prior art.
  • a thermally and mechanically stable microwave plug-in connection is to be provided, which allows use in a cooking appliance in everyday kitchen operation.
  • the microwave connector should be as simple and inexpensive as possible and minimize the susceptibility to interference with ease of use. Also, in the transmission of microwave energy through the connection, the losses should be kept as low as possible.
  • the transmitter unit comprises at least one metallic conductor in conjunction with a metallic ⁇ / 4 structure
  • the receiver unit comprises at least one metallic conductor in conjunction with a metallic ⁇ / 4 structure
  • the dielectric coating is elastically connected to the metallic substrate.
  • the dielectric coating is porous.
  • the dielectric coating is at least partially sealed with a mineral melt for stabilization.
  • the dielectric coating consists of a ceramic material.
  • the outer conductor of the transmitter unit and the receiver unit are galvanically connected to each other or the ⁇ / 4 structure of the outer conductor of the transmitter unit is at least partially provided with a dielectric coating.
  • the dielectric seal terminates the coaxial line of the transmitter unit watertight at least at its end remote from the microwave source, preferably with the interposition of at least one O-ring seal.
  • Embodiments of the invention may be characterized in that one of the inner conductors is in operative connection with a, in particular pin-like, projection, while the other inner conductor which can be plugged together has a recess adapted to said projection, wherein preferably both the projection have a ⁇ / 4 structure and the
  • the projection is part of a contacting, which is positively and / or non-positively connected to the associated inner conductor.
  • the invention proposes that the dielectric seal be arranged between the contacting means and the outer conductor associated with the associated inner conductor, preferably with the interposition of at least one O-ring seal.
  • the invention likewise provides a cooking appliance with a cooking chamber, a technical space separated therefrom via at least one cooking chamber wall, and a microwave plug connection according to the invention, in which the transmitter unit is arranged in the cooking space and receiver unit in the cooking space.
  • the transmitter unit is mechanically, in particular releasably connected to the cooking chamber wall.
  • the invention again proposes that the ⁇ / 4 structure of the outer conductor of the transmitter unit has a thread.
  • the invention is thus based on the surprising finding that a microwave plug connection is thermally and mechanically so stable that it can also be used in a cooking appliance for large and commercial kitchens by using a dielectric as one fixed to a metallic substrate which is connected to a (coaxial) Line is connected and has a ⁇ / 4 structure, connected coating is provided and an at least partially galvanic isolation when connecting the (coaxial) line with another (coaxial) line for transmitting microwaves of wavelength ⁇ is used.
  • the further line can also be equipped with such a dielectric coating.
  • the compound according to the invention is characterized in that the coating is applied elastically and porous on the substrate.
  • the mechanical stability of the connection can also be increased by the fact that the dielectric coating consists of a ceramic material, preferably aluminum oxide, and is advantageously also sealed with a mineral melt.
  • a garraum workede receiver unit and / or a technical room side transmitter unit is provided with a dielectric coating.
  • another dielectric may be arranged on the engineering space side relative to the fluid seal, namely between the inner and outer conductors of the transmitter unit, which galvanically separates the inner and outer conductors of the transmitter unit from one another.
  • the receiver and transmitter unit according to the invention are designed as parts of a retaining, releasable plug. With the help of a thread in the region of the ⁇ / 4 structure of the outer conductor of the transmitter unit, it can be screwed tightly to a cooking chamber wall. Care must be taken that the thickness of the dielectric coating is suitable for the ⁇ / 4 geometry of the compound.
  • FIG. 1 shows a microwave plug connection 100 according to the invention for use in a cooking appliance (not shown) with cooking space walls 10 between a cooking space and a technology room, namely with a garraum disorderen plug in the form of a receiver unit 101 and a plug on the engineering room side in the form of a transmitter unit 102.
  • the receiver unit 101 can be plugged, which in turn has a continuing microwave inner conductor 1 and a continuing microwave outer conductor 3, which are each connected to a receiving ⁇ / 4 structure 3 and 4 respectively.
  • the microwave connector 100 is shown in the plugged state, wherein the receiver unit 101 both positive and non-positive, z. B. with the help of a mother, with the transmitter unit 102 may be firmly connected.
  • the geometry of the ⁇ / 4 structures 2, 4, 5, 9, the dielectric coatings 6, 8 and the sealing dielectric 7 are designed so that the incoming into the transmitter unit 102 microwaves can be transmitted as lossless as possible in the receiver unit 101. This is ensured by the adaptation of the geometry of the components to the wavelength of the microwave ⁇ .
  • the coatings 6, 8 of the ⁇ / 4 structures 5, 9 of the transmitter unit 102 can be produced by means of chemical vapor deposition (CVD) or by means of the deposition of a plasma in the form of a porous ceramic (for example aluminum oxide).
  • CVD chemical vapor deposition
  • a plasma in the form of a porous ceramic (for example aluminum oxide).
  • a coating technique is for example in the US 2005/0260411 A1 described.
  • the thus applied dielectric coatings 6, 8 are characterized by a high mechanical hardness and by a high chemical resistance, which corresponds to that of the metallic parts of the microwave connector 100 of z. As copper, iron, brass or stainless steel far exceeds.
  • the application of the porous ceramic layer by means of CVD or plasma techniques achieves a mechanically extremely stable connection of the dielectric ceramic to the metallic substrate, which also has elastic properties.
  • both the ⁇ / 4 structures 5, 9 of the transmitter unit 102, and the ⁇ / 4 structures 2, 4 of the receiver unit 101 are provided with a dielectric coating.
  • only the ⁇ / 4 structures of the receiver unit 101 may be coated. In any case, care must be taken that the coatings do not give rise to excessive deviations from the optimum ⁇ / 4 geometry of the microwave connector 100 according to the invention.
