  • Direct Air Heating By Heater Or Combustion Gas (AREA)

Abstract

PURPOSE: To avoid wasteful power consumption in a hot-air heater, by providing two heat-sensitive switches having different setting temperatures at or near the combustor of a hot-air heater, and stopping operation of an ignitor while a low-temperature heat-sensitive switch is actuated into operation.
CONSTITUTION: A low-temperature heat-sensitive switch 10 is provided at or near a potlike combustor 1 of a hot-wind heater, and there is also provided a high- temperature heat-sensitive switch 11 having a higher setting temperature than the low-temperature heat-sensitive switch 10. When combustion is started by shifting a control switch 16 to its ON contact 16a and thereby setting a combusting fan 3, solenoid valve 6, solenoid 7, ignitor 8, etc. into operation, the temperature is raised at first to a level of the setting temperature (for instance, 55°C) of the low-temperature heat-sensitive switch 10 and then a normally closed contact 19a of a relay coil 19 is turned OFF by the function of switch 10, so that current supply to ignitor 8 is stopped. At the same time, because another normally closed contact 19d is also turned OFF, so that a timer T operated while the heater fails to ignite is rendered inoperative.
