Embodiment 1

[0013] Such as figure 1 The present embodiment shown includes a fan 1, a flange 2, an air pipe 3, a nozzle 4, a jet pipe 5, a hose flue 6, a flue 7, a smoke hood 8, and the like. The blower fan 1 and the air pipe 3 are connected by a flange 2, and the end of the air pipe 3 has a nozzle 4 with a reduced aperture, so as to increase the injection speed of the air flow. Jet pipe 5 is a three-way pipe, one end of jet pipe 5 is sealed, and air pipe 3 is installed at the end. The entrance of oil fumes. The hose flue 6 connects the jet pipe 5 and the flue 7, and the flue 7 is installed on the top of the fume hood 8.

Embodiment 2

[0015] Such as figure 2 The present embodiment shown includes a fan 1, a flange 2, an air pipe 3, a nozzle 4, a jet pipe 5, a hose flue 6, a flue 7, a smoke hood 8, and the like. The jet tube 5 is a straight tube, one end of the jet tube 5 is the oil fume inlet, and the other end is the mixed outlet of the jet flow and the oil fume. The fan 1 and the air pipe 3 are connected by the flange 2, the air pipe 3 is installed vertically on the jet pipe 5, and the end of the air pipe 3 has a nozzle 4 with a reduced aperture perpendicular to the air pipe 3, so as to increase the injection speed of the air flow, the nozzle 4 On the axis of the jet tube 5. The hose flue 6 connects the jet pipe 5 and the flue 7, and the flue 7 is installed on the top of the fume hood 8.

[0016] The blower fan is equipped with a range hood. When in use, the blower fan 1 sucks in fresh air, and the airflow blown out by the blower fan 1 passes through the air pipe 3, enters the nozzle 4 and sprays out at...

Abstract

The invention relates to a range hood with an external draught fan, and particularly relates to a range hood suitable for household use. The range hood comprises a draught fan (1), a flange (2), an air duct (3), a spray nozzle (4), a jet pipe (5), a soft pipe flue (6), a flue (7) and a hood (8). The draught fan (1) takes in fresh air; air flow blown by the draught fan (1) passes through the air duct (3), enters the spray nozzle (4) and is sprayed out at a high speed; a negative pressure is formed in the jet pipe (5); oil fume in a kitchen is sucked into the hood (8); the oil fume passes through the flue (7) and the soft pipe flue (6); and the oil fume is sucked in by the jet pipe (5) and is sprayed out together with the jet stream. The range hood with the external draught fan is advantageous in that the draught fan takes in the fresh air, blades of the draught fan can be kept clean, and the range hood is in no need of cleaning, and is convenint for use.

Description

technical field [0001] The invention relates to a range hood with an external fan, in particular to a range hood suitable for household use. Background technique [0002] Currently used range hoods are generally installed in the hood with a fan, so the fan blades of the fan are prone to sticking to oil and need to be dismantled and cleaned regularly, which is very inconvenient. Contents of the invention [0003] The object of the present invention is to design a range hood with an external blower fan which does not need to be cleaned. [0004] The present invention includes a fan 1, a flange 2, an air pipe 3, a nozzle 4, a jet pipe 5, a hose flue 6, a flue 7, a fume cover 8, and the like. The blower fan 1 and the air pipe 3 are connected by a flange 2, and the end of the air pipe 3 has a nozzle 4 with a reduced aperture, so as to increase the injection speed of the air flow. Jet pipe 5 is a three-way pipe, one end of jet pipe 5 is sealed, and air pipe 3 is installed at t...
