Abstract
PURPOSE: To stabilize the combustion of the hot water heater of the type in which burners are combusted with forced circulation of air, by keeping the primary air rate substantially constant independently of the gas flow rate through employment of such an arrangement that suction of primary air to the burners is dependent mainly on the ejector function exerted when gas is ejected from nozzles.
CONSTITUTION: When a fan 7 is set into rotation in response to the instruction of a controlling unit, the air discharged from the outlet of the fan 7 is made to flow downward in an air passage 6 defined between the outer wall surface of a heating case 1 and the inner surface of an outer case 5 while cooling the outer surface of the inner case 1, in which a combustion chamber 3 is defined. The air flow is divided into two parts at a communicating part 8 communicated to the combustion chamber 3. Most of air is introduced into the combustion chamber 3 as shown by the arrows of solid line, and a part of air is used as the secondary air for combusting gas while other part of air flows along the inner wall surface of the heating case 1 and cools the same. Remainder of the shunted air flow is introduced into the primary air chamber 18 via small thru-holes 19 and drawn into the burners 13 as the primary air by the ejector function exerted when gas is ejected from the nozzles 14.
