PROBLEM TO BE SOLVED: To provide a power supply device for a combustion equipment which can be driven by either a commercial power supply or a battery. SOLUTION: A selecting means which selects a commercial power supply or a battery 15 as a drive power supply and a change-over means which changes the connection destination of the commercial power supply or the battery 15, when the power is supplied from the commercial power supply, are provided. When the selecting means selects the commercial power supply, a combustion apparatus is driven by the commercial power supply and the change-over means connects the commercial power supply to the battery 15 by the power supply from the commercial power supply to charge the battery 15. When a power is not supplied from the commercial power supply, the operation of the combustion apparatus is stopped. When the change-over means releases the battery 15 and the selecting means selects the battery 15, if a power is supplied from the commercial power supply, the battery 15 is released from the combustion apparatus by a selecting means and the change-over means to stop the combustion apparatus and the commercial power supply is connected to the battery 15 to charge the battery 15, and if the power supply from the commercial power supply is discontinued, the combustion apparatus is driven by the battery 15 and the charging of the battery 15 is discontinued. |
