Abstract

The invention relates to a smoke exhaust structure and a positive pressure partition gas displacement balanced distribution system, and solves the problem that a range hood cannot prevent reverse backflow of oil smoke. The smoke exhaust structure comprises a range hood, a smoke exhaust pipe and a fireproof valve, the range hood comprises a machine shell, an air exhaust executing mechanism, a first driving mechanism and the smoke exhaust valve, an air exhaust channel is formed in the machine shell, at least part of the air exhaust executing mechanism is arranged in the air exhaust channel, and the air exhaust channel comprises a first air inlet and a first air outlet. The part, located between the first air inlet and the air exhaust executing mechanism, of the air exhaust channel is an air inlet section, the part, located between the air exhaust executing mechanism and the first air outlet, of the air exhaust channel is an air outlet section, and the smoke exhaust valve is arranged on the machine shell to open or close the air outlet section.

Description

technical field [0001] The invention relates to a smoke exhaust structure and a system for equalizing exhaust volume distribution of positive pressure zones. Background technique [0002] Existing range hoods include a casing, a motor and an impeller, wherein the casing is provided with an air extraction channel, the air extraction channel includes a first air inlet and a first air outlet, the impeller is arranged in the air extraction channel, and the motor is arranged on the The casing, the motor and the impeller are connected in rotation. When the motor drives the impeller to rotate, the oily fume enters the air extraction channel from the first air inlet, and is discharged to the outside of the range hood through the first air outlet of the air extraction channel, so as to realize the normal operation of the range hood. To exhaust smoke. However, the existing range hood cannot prevent the oil fume from backflowing backwards. Contents of the invention [0003] The pro...
