An improved choke seal arrangement, in a microwave oven, in which a slit structure is provided to prevent leakage of microwave energy around the periphery of the door. The slit structure, which has been provided in one of the walls defining the choke cavity in the prior art choke seal arrangement, is provided in a door wall portion spaced apart from the choke cavity so as to facilitate mechanical formation of the choke cavity and also to prevent deformation of the choke cavity wall during use. The choke seal arrangement permits the gap between the wall of the choke cavity and the confronting inner wall of the heating chamber to be smaller than hitherto, and the microwave seal performance further improved. |
