Title:
HEATING COOKER
Document Type and Number:
WIPO Patent Application WO/2017/141298
Kind Code:
A1
Abstract:
Included are: a first heating device that heats a lower surface of a placement plate; a second heating device (19) that heats an upper surface of the placement plate; and a control unit that controls the output of the first heating device and that changes energization to the second heating device (19) depending on the type and the quantity of an object to be heated. Furthermore, the second heating device (19) has two plate-like insulators (34, 35) and a plurality of planar heating elements (18a, 18b) sandwiched between the insulators (34, 35). The control unit controls energization to the first heating device and the second heating device (19), thus heating vertically opposing regions with the placement plate sandwiched therebetween. Furthermore, the second heating device (19) is provided with a strain suppressing unit between the plurality of planar heating elements (18a, 18b), and the strain suppressing unit suppresses internal strain in the insulators (34, 35) caused by heating of the plurality of planar heating elements (18a, 18b) of the second heating device (19).
