Title: Floor heating cork panel
Inventor: ITO TARO
IPC: F24D3/16
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To effectually heat a floor surface by mixing cork particles and a bonding agent and integrally compressing and molding them together with a resilient heat insulation material on a metal top plate to which a warm water circulation pump is connected. SOLUTION: There are integrally provided a metallic top plate 2 for increasing a lateral heat transfer characteristic and dispersing a point load to a surface load, a warm water circulation pipe 1 making close contact with the back of the top plate and formed into a meandering and spiral shape, through which warm water passes, and a resilient heat insulating material 3 using a cork material as a core material. Actually, the heated warm water circulation pipe 1 is interrupted in its most part of heat transfer by the resilient heat insulating material 3 surrounding the pipe 1, and it transmits all its heat only to the metal top plate 2 in close contact therewith. Hereby, the metal top plate 2 containing heat achieves satisfactory floor heating with the aid of its wide heat dissipation area. Thus, a comfortable environment is ensured.
