The invention relates to a sealing arrangement for microwave ovens, comprising an attenuation choke (20) extending around an access opening (11) to an oven cavity (10) and arranged either in the cavity wall portions surrounding the access opening (11) or in the rim portions of a door (19) closing the opening. According to the invention the choke (20) has a generally G-shaped profile, the horizontal inner leg of the G forming a partition wall (23) in the choke (20), which partition wall (23) on one side bounds an entrance opening (26) to the choke (20) and on the other side is contiguous with a wall forming a short-circuiting wall (24) and at the same time bounds an output portions of the gap between the door (19) and the cavity walls. Either the partition wall (23), or the short-circuiting wall (24), or both, are provided with slots (25) extending transversally to the circumference of the door (19) or access opening (11). |
