Title:
COMBUSTION DEVICE AND WATER HEATING DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2024/075504
Kind Code:
A1
Abstract:
A combustion device C comprises: a burner B for the combustion of fuel gas; a pressure regulating valve V that is provided to a fuel gas supply route 3 to the burner B and controls the fuel supply pressure to the burner B so as to obtain a pressure corresponding to a signal pressure Ps; a first fan 1A that is driven by the motor M and serves to supply air for combustion to the burner B; and a second fan 1B that is driven by the motor M, intended for use together with the drive source of the first fan 1A, and makes it possible to take in and discharge air at the time of driving. The air discharge pressure of the second fan 1B is used as the signal pressure Ps. It is thus possible to reduce the driving speeds of the first and second fans 1A, 1B and reduce noise while ensuring that the flow rate of the air supply for combustion and the fuel supply pressure to the burner B are adequate.
