Title: Floor heating device
Inventor: NAGASE NORIYOSHI
IPC: F24D13/02
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To provide the floor heating comfortable both for a walking person and for a seated person by suppressing the heating value of a heat source corresponding to the load on the floor to realize the partial temperature adjustment of a floor heating panel in a floor heating equipment in which the heat source is installed below the floor to perform the heating from the floor surface. SOLUTION: When the weight of a person is applied to the floor surface, a spring 26 is contracted by the weight of the person, and an upper conductive flat plate 21 and a lower conductive flat plate 22 in a floor heating panel are brought close to each other. The area of the adjacently sliding contact surface of an upper heat generating body 24 with an lower heat generating body 24 is reduced. The current is difficult to flow because the contact surface of the upper heat generating body 23 with the lower heat generating body 24 is reduced, and the heating value at a part of the floor heating panel under the load is smaller than a part of the floor heating panel without any load. Thus, the temperature on the floor surface of the part under the load is lower than that of the part without any peripheral load. The local temperature suppression can be realized.
