Abstract
PURPOSE: To improve the heat insulation efficiency of a heating chamber without complicating its structure by a method wherein the internal surface of the wall of the heating chamber is covered with a heat insulating layer.
CONSTITUTION: A high frequency heating apparatus attached with electrical heaters has a magnetron 9 provided outside the wall 8 enclosing the heating chamber 2. Further, there are provided the electrical heaters 10 and 10 at the upper and lower sections of the heating chamber 2, respectively. The internal surface of the wall 8 of the heating chamber is lined with the heat insulating layer 12 consisting of ceramics, bricks or the like. The hest insulating layer 12 is lined over nearly the entire internal surface of the heating chamber wall with the exception of the vibration exciting port of the magnetron 9 and a part through which the shaft of a rotary dish 11 passes. The front plate 13 of the heating chamber is arranged in such a manner that the opening edge 13a of the heating chamber projects forwardly of the front end face 12a of the heating chamber wall 8 by a length S2 which is equal to, or greater than, the thickness S1 of the heat insulating layer 12 so that the front end face 12a is covered by the insulating layer 12.
