Title:
HEATING CONTROL DEVICE
Document Type and Number:
Japanese Patent JPS6095602
Kind Code:
A
Abstract:
PURPOSE:To shorten a time of a heating delay by detecting a variation tendency of a temperature, and starting beforehand a combustion before reaching a set temperature. CONSTITUTION:A temperature A of an object to be heated is detected by a detecting part 11, this output is compared with a comparing level C1 by the first comparing part 12, and its crossing part T1 is counted by a time counting part 13. Also, said detecting output is compared with a comparing level C2 by the second comparing part 14, and its crossing time T2 is outputted. As a result, AND of a time counting output of said time counting part 13 and said comparing output becomes an outut of a control part 15, a variation tendency of a temperature is foreknown by using said output as a combustion start signal, and a combustion is started in advanve before a time T3 when a control output reaches a heating set temperature C3.
