Abstract
The utility model provides a smoke exhaust structure which is communicated between a kitchen range hood and a building common exhaust passage. The smoke exhaust structure comprises a non-return valve and first and second exhaust pipes, wherein the non-return valve is provided with a gas inlet and a gas outlet, the gas inlet of the non-return valve is communicated with the exhaust port of the range hood through the first exhaust pipe, and the gas outlet of the non-return valve is communicated with the air inlet of the common exhaust passage through the second exhaust pipe. In the smoke exhaust structure, the mounting position of the non-return valve is lowered through the second exhaust pipe, which solves the problem that the non-return valve which is directly mounted to the gas inlet of the common exhaust passage (in a suspended ceiling) is too high to change and clean; and besides, the mounting position of the non-return valve is raised through the first exhaust pipe, which solves the problem that the non-return valve which is directly mounted to the exhaust port of the range hood through (in the range hood) is too low to change and clean. Therefore, the smoke exhaust structure is particularly suitable for kitchens with suspended ceilings, and helps improve safety and reliability of smoke exhaust and backflow prevention.
