The invention belongs to the technical field of a kitchen electric appliance, and particularly relates to an exhaust hood with a
smoke collecting cavity capable of ascending and descending. By aimingat the defects of the existing lateral suction type exhaust hood with the
smoke collecting cavity capable of ascending and descending that the
smoke collecting cavity is built in a casing, so that oilstain can be easily leaked out from a position between the casing and the smoke collecting cavity, the exhaust hood provided by the invention has the following technical scheme that the exhaust hoodwith the smoke collecting cavity capable of ascending and descending comprises a smoke box, a fan, a
flue, the smoke collecting cavity, an ascending and descending mechanism and a guide mechanism, wherein the smoke collecting cavity is arranged outside the glue in a way capable of ascending and descending; the smoke collecting cavity is provided with an
air door; the
air door is positioned at thefront side surface of the smoke collecting cavity; the insides of the smoke box, the
flue and the smoke collecting cavity are communicated to form an oil smoke passage. The exhaust hood has the beneficial effects that the smoke collecting cavity capable of ascending and descending is arranged outside the
flue; oil
stain cannot be accumulated on the outer surface of the smoke collecting cavity; theoil
stain between the flue and the smoke collecting cavity can be collected in the smoke collecting cavity without flowing out; the dimension in the left and right direction of the smoke collecting cavity can be made to be big; under the identical conditions, the
air door area of the smoke collecting cavity can be larger.
