摘要： PROBLEM TO BE SOLVED: To provide a combustion controller for oil hot air heater in which convenience is enhanced without sacrifice of the feeling of heating by roughly indicating the combustible time after detecting oil supply thereby notifying the residual combustion time to a user without causing any trouble. SOLUTION: Residual time up to final indication is set longer than the indicating time after switching but shorter than the indicating time after switching to the final indication. Since a short combustible time can be notified to a user and the user can alter combustion when the heating load is varied due to variation in the condition of working environment after oil supply is detected, the feeling of heating is not damaged and the residual combustion time can be set optimally depending on the working conditions. Convenience is enhanced significantly by notifying the remaining fuel in the tank, and thereby the residual combustion time, to the user through an oil supply detecting/notifying means 23 without causing any trouble.

摘要： PROBLEM TO BE SOLVED: To eliminate the occurrence of power consumption in a state where an operating switch is turned off in a combustor having a group of loads requiring delayed actions. SOLUTION: A combustion controller is provided with a group 13 of loads containing such a load that requires delayed action even after an operating switch 11 is turned off, a control section 15 which controls the group 13, an open/close signal transmitting means 11a for the switch 11. The controller is also provided with an opening/closing means 12 which performs prescribed opening/closing operations upon receiving signals from the transmitting means 12. The power supply opening/closing means 11b of the operating switch 11 and the opening/closing means 12 are connected in parallel with each other to control the power supply to the group 13 of loads and control section 15.

摘要： PROBLEM TO BE SOLVED: To improve the ease of use by temporarily increasing heating capability in normal operation with a simple switch operation. SOLUTION: In hot air heater that is equipped with a temperature detection means 1 for detecting room temperature, a combustion part 3 for burning fuel, and an amount-of-combustion control part 4 for controlling the amount of combustion in multiple stages based on room temperature information and setting temperature being detected by the temperature detection means 1, the amount-of- combustion control part 4 forcibly fixes the amount of combustion to a specific value merely for a specific period when specific operation 9 other than the change of the setting temperature is made, and automatically returns to amount- of-combustion control based on the normal room temperature information and setting temperature after the specific period.

摘要： PROBLEM TO BE SOLVED: To obtain a conduction circuit for a combustor controlling a load group through a drive element being driven with the output from a control section in which power consumption is prevented by interrupting power supply to a control section through a specified operation after an operating switch is turned off. SOLUTION: A first switching means 1 for switching power supply to a control section 8 and a load group 5 is connected in parallel with a second switching means 2 performing switching operation based on a signal from the control section 8. The second switching means 2 is opened after executing an stopping operation for starting operation by closing the second switching means 2 when the first switching means 1 is operated to be closed and including a delay operation when the first switching means 1 is operated to be opened.

摘要： PROBLEM TO BE SOLVED: To conduct operation according to optimal operational information while eliminating power consumption after an operating switch is turned off. SOLUTION: A combustion controller comprises an operating switch 11, a power supply circuit 14 connected in parallel with the operating switch 11, a load group 12 performing combustion operation, a control section 13 for the load group 12, and a nonvolatile memory 15 for storing operational information. Upon receiving an ON signal from the operating switch 11, the control section 13 controls the load group 12 based on operational information read out from the nonvolatile memory 15. Upon receiving an OFF signal from the operating switch 11, the control section 13 interrupts power supply after operation of the power supply circuit 14 is stopped.

摘要： PROBLEM TO BE SOLVED: To display a combustible time by real time system and to improve handling operability by calculating a combustion continuable time in response to a combustion amount at that time or a preset combustion amount when a fuel of a predetermined residue is detected, and displaying it. SOLUTION: When fuel is retained at a residue A, a combustible time (T0) of a predetermined combustion amount and a fuel consumption amount (Q0) per unit time of the predetermined combustion amount are preset. When a fuel consumption amount (Q1) per unit time for the combustion amount when the fuel of the residue A is actually detected by a residue detecting means 5 is Q1, a combustible time (T1) responsive to the combustion amount when the residue A is detected becomes T1=T0×Q0/Q1. The combustible time calculated by a combustible time calculating means 7 is counted by a combustible time counting means 8, and the counted time is displayed on a display unit 9.
