Document Type and Number:
Japanese Patent JP2016199431
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a baking furnace that suppresses deformation and destruction of a heat insulating material of a furnace door and improves the degree of sealing of a furnace chamber with a small number of components.SOLUTION: A baking furnace comprises a furnace body having a furnace chamber surrounded by a first heat insulating material, and a furnace door openably and closably mounted to the furnace body for closing an opening of the furnace chamber. The furnace door includes a door body, a second heat insulating material facing the furnace chamber, and a holding member holding the second heat insulating material. The second heat insulating material is brought into contact with the first heat insulating material at a peripheral part of a back surface facing the furnace chamber with the furnace door closed. The holding member is brought into contact with a peripheral part of a front surface of the second heat insulating material and has a plate spring that energizes the second heat insulating material toward the furnace chamber.SELECTED DRAWING: None
