Japanese Patent JP3721273
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To safely control a heating operation before a burning damage to an operation panel occurs at the time of stopping a supply fan during heating or bringing about a clogging accident of a warm air exhaust port.
SOLUTION: An operation panel temperature sensor 19 fixedly wired together with other component in the case of passing a wiring printed circuit of a rear surface of an operation panel 13 provided on an upper surface of a warm air heater body 1 is provided. When the sensor 19 senses the temperature of the rear surface of the panel 13 in which an abnormal temperature rise occurs caused by an exposure with a radiant heat from a warm air chamber wall 11 in which an abnormal overheat occurs, a central controller effectively stops a combustion operation of a burner 2, thereby assuring a safety of the heater.
