Claims

[Scope of utility model registration request]

A gas burner B and a heat exchange section 16 for boiling water disposed above the gas burner B are provided in the vertically oriented cylindrical body 15, and in order to form the gas burner B, gas fuel and primary air for combustion from the electric fan 12 are mixed. With the combustion surface forming walls 3 and 4 extending upward from one side edge of the flame port 5 that spouts the mixed gas upward, located outside the upwardly extending portion A of the flame port 5, The secondary air blower is provided in an inclined or vertical position that is farther away from the point A corresponding to the upward extension of the flame outlet 5 toward the upper side, and supplies secondary combustion air from the electric fan 12 to the combustion space 6 for the flame outlet 5. The discharge port 14 of the air supply path 13 is connected to the combustion surface forming walls 3 and 4 by imaginary lines extending upward from both ends of one side edge of the flame port 5 on the surfaces of the walls 3 and 4. It is an instantaneous water heater that is formed continuously or intermittently along a section of the secondary air supply path 13 that is located at the back of the combustion surface forming walls 3, 4, and The cooling air passage 17 is connected to the secondary air supply passage 13 at its lower end and connected to the cylindrical body 15 at its upper end.
An instantaneous water heater connected below the water heating heat exchange section 16 near the inside of the water heater.
