Title:
RADIO FREQUENCY HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/181318
Kind Code:
A1
Abstract:
A surface wave transmission line (103) provided in the vicinity of a table (101) has a slope with respect to the transmission direction of radio frequency power. Therefore, the distance between the surface wave transmission line (103) and the table (101) is larger on the radio frequency power feeding unit (120) side. Accordingly, the farther away from the radio frequency power feeding side of the surface wave transmission line (103), the greater the absorption of the radio frequency power propagating through the surface wave transmission line (103) by the object (102) to be heated. As a result, uniform heating is achieved even when a plurality of objects are placed side-by-side along the propagation direction of the radio frequency power in the surface wave transmission line (103) or when an object (102) with a long length is placed therealong. In addition, since the table (101) can be kept in a horizontal state, problems such as rolling of the object (102) can be prevented.
