Premixing device and gas water heater |
| abstract |
The invention discloses a premixing device and a gas water heater, wherein the premixing device comprises a casing and a spoiler assembly; the casing has an air inlet, an air outlet and a premixing chamber communicating with the air inlet and the air outlet; the spoiler assembly is arranged on the In the premixing chamber, the spoiler assembly includes a cylinder body, a first spoiler blade and a second spoiler blade. Both ends of the cylinder body are communicated with the premixing chamber. The first spoiler blade is arranged in the cylinder, and the second spoiler blade is set. Between the cylinder body and the casing, the installation direction of the first spoiler vane is opposite to that of the second spoiler vane, so that the direction of rotation of the airflow passing through the first spoiler vane is the same as that of the airflow passing through the second spoiler vane. The direction of rotation is opposite. The premixing device of the invention can make the mixing of gas and air more uniform, and the premixing device has a simple structure and small wind resistance. |
