Document Type and Number:
Japanese Patent JP3374626
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hot air heater in which fuel is ignited and applied for heating operation, wherein a reduction in the number of rotation of a blower is corrected to prevent a fast stopping of combustion and it can be operated safely for a long period of time. SOLUTION: As the number of rotation of a blower 15 for assisting combustion at a burner part 11 is decreased and an amount of electrical current obtained by a combustion sensor 13 is decreased less than a predetermined value due to a certain reason, an air blowing control part 20 increases the number of rotation of the blower 15 so as to cause the rotation of the blower 15 to be continued. Then, a slight large amount of a part of the air blown by the blower 15 is supplied to the burner to enable a stable combustion to be carried out, resulting in that it becomes possible to prevent air from being reversely flowed to the burner part due to a clearance air or the like or to prevent a fast cutting of combustion stopped state caused by the reduction in the number of rotation of the blower 15.
