Example one
Referring to fig. 1 to 4, the oil-dripping-preventing smoke circulating pipeline provided by the present application is used in a range hood, and the range hood specifically shown in the figures is an european range hood.
Specifically, the oil-dripping-preventing smoke circulation pipeline comprises a telescopic smoke collecting hood 101, a smoke guiding tube 102 and an oil baffle 103.
The telescopic fume collecting hood 101 is located at the bottom of the main body casing 116 of the range hood, and plays a role in collecting fume, so as to prevent the fume from escaping. The telescopic fume collecting hood 101 includes a moving hood body 104, the moving hood body 104 being movable relative to a main body housing 116 in a first direction, specifically, a front-rear direction (a direction shown in fig. 1) of the range hood; the moving cover 104 reciprocates along the first direction to achieve the function of stretching, so as to change the range of the smoke-gathering area, and completely suck away the oil smoke generated by the cooker.
In order to avoid the phenomenon of smoke escape at the rear part of the range hood, the telescopic smoke collection hood 101 further comprises a fixed hood body 105 which is fixed relative to the main body shell 116 of the range hood, and the fixed hood body 105 is located at the rear part and remains immovable, so that the effect of collecting smoke at the rear part can be realized, and the smoke escape is avoided.
