CONTROL METHOD OF ACTUAL TEMPERATURE OF INTERMITTENTLY OPERATED HEATING MEANS

摘要

PROBLEM TO BE SOLVED: To control actual temperature of an intermittently operated heating means. SOLUTION: At least a single operation parameter is measured for a prescribed measuring period T in a switch-on period 86 of a heating means. An actual temperature of the heating means is detected on the basis of a measured value of at least this single operation parameter. A length of the switch-on period 86 at that time is changed on the basis of a compared result of the actual temperature and a prescribed target temperature. The shortest length of respective switch-on periods 86 is equal to the measuring period T. The measuring time T is selected on condition that heat energy supplied to the heating means in a length of the measuring time is successively smaller than heat energy generated in a switch-off period 88 extending up to the next switch-on period.
