Definitions

  • the invention relates to a lamp for microwave ovens according to the preamble of claim 1.
  • microwave ovens in general, there is an imperative requirement that radiation of microwave energy outside the oven space provided for the heat treatment of food must be prevented.
  • microwave ovens with lighting devices for illuminating the oven space there is the problem in this respect that a more or less large opening must be provided for the lighting arrangement in the oven wall, through which microwave rays could escape to the outside when the lamp is not in the lamp holder and / or if there is not a special, microwave-proof shield in the correct position on the aforementioned opening with all-round metallic contact with the furnace wall. This danger exists if the lamp has to be changed.
  • the aforementioned opening in the oven wall can be closed in a microwave-tight manner by a transparent cover which can be placed on the opening and which contains a metallic screen grid and is in direct contact with the oven wall in the closed position.
  • This cover has a metallic socket for the lamp and is connected to a safety switch, such that only with the correct insertion of Cover and socket of the safety switch is actuated and the microwave generator of the microwave oven can be switched on.
  • the invention has for its object to design a lamp for microwave ovens so that they emit microwave radiation without a special safety switch with a simple design even when careless handling of the lamp, e.g. when replacing the lamp, prevented.
  • 1 denotes part of the oven wall, for example the side wall of a microwave oven, of a type known per se, which surrounds an oven space, which is generally indicated at 2.
  • this furnace wall has an opening 4, behind which there is a lamp chamber 6 which is formed or enclosed by a lamp housing 5.
  • the lamp housing 5 is connected directly to the furnace wall 1 by a flange 7 that surrounds it, for example by welding.
  • An elastic seal 8 is located on the flange 7.
  • An electrical lamp holder 9 for a lamp 10 which can be inserted or screwed therein is fastened to the upper side wall of the lamp housing 5 in FIG. 1.
  • the luminaire housing has a plurality of snap-in elements 11, which are bent inward and spring-like on the circumference and onto which a transparent cover 12 made of glass-like material with a circumferential collar 13 constricted on the outer circumference can be attached and can be locked and can be removed from the locking elements 11.
  • the cover 12 is supported on the seal 8 and mechanically closes the lamp chamber 6 to the furnace chamber 2, so that no contamination of the lamp chamber 6 can take place during operation of the microwave oven.
  • 14 designates a shield in the form of a metallic, lattice-like basket, which in the closed position according to FIGS.
  • the shield 14 can be pivoted about a pivot axis 15 on a stationary furnace part, ie in the present case on the stationary lamp housing 5.
  • a torsion spring 16 which is supported on the one hand on the lamp housing 5 and on the other hand on the shield 14 with prestress and which causes the basket-like shield 14 after pivoting into the open position according to FIG. 2, in which the furnace chamber 2 forth the lamp 10 can be removed from the lamp holder 9, automatically returns to the closed position according to FIG. 1 by the force of the torsion spring 16.
  • the shield 14 latches with an edge part in a U-shaped latching element 17 according to FIG. 4, which is fastened to the lamp housing 5 in the region of a constriction 18. If the shield 14 is in the closed position according to FIGS. 1 and 3, microwave rays coming from the furnace space 2 cannot reach the region of the lamp chamber 6 which is metallically enclosed by the shield 14 and the lamp housing 5 in the area of this shield by the lamp holder 9 located.
  • the design of the shield 14 ′ differs with respect to the embodiment according to FIGS. 1 to 4.
  • this shielding is not designed in the form of a basket, but rather forms an essentially flat grid which runs through the lamp housing 5 in its entire clear width and after removing the cover 12 from the closed position according to FIG. 5 in the direction of the arrow into an open position against the force the torsion spring 16 can be pivoted about the pivot axis 15. In this open position, the lamp 10 is again freely accessible, after which the shield 14 'again moves automatically into the closed position.
  • the disk-shaped cover 12 ' which is made of glass-like material
  • the essentially planar shield 14' which is connected to the cover 12 'by flanging the edges, form a one-piece component which rotates about a pivot axis directly attached to the furnace wall 1 15 can be pivoted in the direction of the arrow, this component again being able to be automatically reset to the closed position with large-area contact with the furnace wall 1 by spring force or simply by gravity after the pivoting into the open position.
