Title:
SMOKE EXHAUST ASSEMBLY AND SMOKE EXHAUST DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/120598
Kind Code:
A1
Abstract:
Disclosed are a smoke exhaust assembly (10) and a smoke exhaust device. The smoke exhaust assembly (10) comprises a draft fan (12), a vortex generating portion (14), a smoke inlet pipeline (16) and a smoke exhaust pipeline (18). The vortex generating portion (14) comprises a vortex pipeline (142) and an air inlet channel (144). The air inlet channel (144) is in communication with the vortex pipeline (142). An inlet of the air inlet channel (144) is connected to the draft fan (12), and an outlet (1443) of the air inlet channel (144) is constructed to generate a vortex-type updraft in the vortex pipeline (142). The smoke inlet pipeline (16) and the smoke exhaust pipeline (18) are in communication with the vortex pipeline (142). An outlet (161) of the smoke inlet pipeline (16) is arranged above the outlet (1443) of the air inlet channel (144), and the outlet (161) of the smoke inlet pipeline (16) is constructed to be in communication with a low-pressure area of the vortex-type updraft. The smoke exhaust pipeline (18) is connected to an outlet of the vortex pipeline (142). When the smoke exhaust assembly (10) is applied to the smoke exhaust device, oil smoke cannot pass through an impeller of the draft fan (12) and cannot adhere to the impeller, thereby improving the oil smoke exhaust effect of the smoke exhaust assembly (10) and enabling the draft fan (12) not to be prone to damage.
