Title:
MULTISTAGE HEATING DEVICE
Document Type and Number:
Japanese Patent JP2013134042
Kind Code:
A
Abstract:

To provide a multistage heating device having a simple structure in which a space between opening and closing doors that are vertically juxtaposed can be minimized, so that processing efficiency is improved, and in which airtightness when the doors are closed can also be improved.

In a multistage heating device, one ends of upper supporting arm bodies 6 and lower supporting arm bodies 7 are turnably provided to upper and lower parts on both right and left sides of each opening and closing door 4, and the other ends of the upper supporting arm bodies 6 and the lower supporting arm bodies 7 are turnably pivoted to both right and left side parts of a furnace body 1 to configure a parallel link mechanism part 8. By the parallel link mechanism part 8, each opening and closing door 4 is moved in parallel from a closed state of a front face open part 2 to a state where each opening and closing door is moved in parallel in front of another opening and closing door 4 adjacent thereto while projecting to the front side, thereby opening the front face open part 2 which had been closed by this opening and closing door 4. A driving device part 9 for rotatably driving the parallel link mechanism part 8 is also provided.
