HIGH FREQUENCY HEATING DEVICE

摘要

PURPOSE:To facilitate cleaning the inside of a heating chamber and decrease wave leak of a light frequency heating device which measures the weight of an object to be heated in th heating chamber, by fixing a turn table at the same electrical postential with the walls of the heating chamber by driving the turn table with a rotating disk having a magnet. CONSTITUTION:A low dielectric loss sleeve 18 having a flange is interposed between a turn table shaft 7 and a choke 14. This works as water sealing of the heating chamber facilitating an easy vertical sliding of the turn table 4. A leaf spring 15 is placed close to the choke 14 to minimize a stroke (d) and to cause a leaf spring 15 to close the opening 14 of the choke when the turn table 4 is removed. Demountable turn table makes cleaning easy and sticking of a finger into the opening is prevented while in operation because the opening is completely closed.
