Abstract: Some embodiments provide a gas device, the gas device includes a frame and a baffle; the baffle is arranged in the frame, the baffle includes an air guide portion and a heat insulation portion, the air guide portion and the frame are enclosed to form a first air guide channel, and the air guide portion is provided with a first air outlet, the first air outlet communicates with the first air guide channel, and faces the heat insulation portion. In the gas device provided by the present disclosure, a baffle is arranged on the inner side of the gas device, and the baffle can reduce the heat transferred from the inside of the gas device to the gas device, reducing the temperature of the gas device, and reduce the impact of the high temperature generated by the burner on the sheet metal components such as the gas device.

Abstract: The present disclosure discloses a combustion chamber and a combustion apparatus. The combustion chamber includes: a first surrounding plate located on an outer side and a second surrounding plate located on an inner side. A combustion cavity is defined by the second surrounding plate. The first surrounding plate and the second surrounding plate are spaced apart from each other to define at least one air duct in communication with the combustion cavity. Each of the at least one air duct has an air inlet hole formed in the first surrounding plate, and an air outlet hole formed in the second surrounding plate.
