HIGH FREQUENCY HEATING DEVICE

摘要

PURPOSE:To improve a sealing characteristic between a metallic frame and an outer frame, prevent stain at an inner screen and an outer screen as well and concurrently simplify a sealing operation. CONSTITUTION:Hardening at room temperature silicone rubber 10 of non- adhesive type is applied to a metallic frame 5 and an outer frame 7 before assemblying and hardened after assemblying. With such an arrangement, the silicone rubber 10 is well adhered to the surfaces of the metallic frame 5 and the outer frame 7 to make their close fitting, resulting in that a high sealing characteristic can be attained and stain at the screens can be prevented. As compared with a cushion rubber 10, its workability is also better.
