Claims

[Scope of Claim for Utility Model Registration] 1. Combustion system that has a hot water supply channel that branches off from the hot water supply channel to supply or fill the bathtub with hot water, a water supply water flow detection device is installed on the hot water supply side, and the system switches to give priority to hot water supply. A combustion appliance characterized in that the bypass valve device for the appliance is provided with a bypass passage that does not pass through a heat exchanger from the water supply passage to the hot water supply passage, and the bypass passage is provided with a bypass valve that opens and closes depending on the presence or absence of water flow in the hot water supply passage. bypass valve device. 2. The bypass valve device has a high pressure chamber separated by a diaphragm and communicating with the pouring water channel, a low pressure chamber communicating with the atmosphere, and a bypass valve that opens and closes the bypass passage by moving the diaphragm, and when the valve is closed, it communicates with the atmosphere. 2. The bypass valve device for a combustion appliance according to claim 1, wherein the valve closes slowly by reducing the passage area of the hole.
