COMBUSTION CHAMBER STRUCTURE AND GAS WATER HEATER

Disclosed are a combustion chamber structure and a gas water heater using the combustion chamber structure. The combustion chamber structure comprises: a housing, a combustion chamber as well as an opening and air inlet holes communicated with the combustion chamber being provided in the housing; a combustor accommodated in the combustion chamber and provided with a combustion burner; and an exhaust support connected between the combustor and the inner wall of the combustion chamber and separating the combustion chamber into a combustion cavity communicated with the opening and a flow guide cavity communicated with the air inlet holes. The combustion burner is located in the combustion cavity; a heat insulation gap communicated with the flow guide cavity is further formed between the exhaust support and the inner wall of the combustion chamber; the exhaust support is provided with multiple flow guide holes and multiple heat insulation holes at intervals; the flow guide holes are communicated with the combusti
