This is because this type of oil guide structure is usually equipped with an oil guide device at the bottom of the air duct. The oil guide device is directly installed at the bottom of the air duct without direct contact with the inner wall of the air duct. The oil droplets formed on the inner wall of the air duct cannot be guided well, and will directly drop on the surface of the stove, and thicker and thicker oil stains tend to accumulate on the inner wall of the air duct
In addition, the existing oil guiding device is usually far away from the oil receiving device, so not only may small oil droplets splash out from the inside of the air duct at any time, but also it is more likely that the oil droplets will fall on the outside of the oil receiving device, and due to the external The oil guide device is installed, so that the structural design of the outer oil screen assembly is limited

Embodiment Construction
[0019] combine figure 1 and figure 2 The present invention is described in further detail, wherein figure 1 with figure 2 Arrows in are the flow direction.
[0020] An air duct oil guide structure of a range hood, comprising an air duct 1 installed in a case, an outer oil cup fixed at the bottom of the case, and a fan unit 2 fixed in the air duct, the top of the air duct is provided with a The opening 3 connected to the base of the smoke exhaust pipe is based on the installation direction. On the top wall 11 of the air duct at the opening 3, there are two opposite flow guide top plates 4. The two flow guide top plates and The included angles at the opening are all obtuse angles, and both sides of the diversion top plate are locked on the circumferential side wall 12 of the air duct, and the locking method can be screw locking. An inner oil cup 5 is fixed directly below the fan unit, and the horizontal projection of the fan unit is included in the horizontal projection of...

The invention discloses an air duct oil guide structure of a range hood. Two guide top plates with a certain inclination are fixed on the top wall of the air duct at the opening of the oil guide structure, and are fixed directly below the fan unit. An inner oil cup that can guide oil drops to the outer oil cup. This structure can guide the oil droplets attached to the inner wall of the air duct to flow into the oil cup in time, avoiding the splashing or dripping of oil droplets to the outside of the oil cup , to ensure the cleanliness of the inside of the air duct, reduce the extra power consumption of the motor, and not affect the structural design of the outer oil network.
Description
technical field [0001] The invention relates to an oil guide structure of a range hood, in particular to an air channel oil guide structure of a range hood. Background technique [0002] Although the oil-guiding structure is provided in the existing range hood on the market, its structural design is not very reasonable. This is because this type of oil guide structure is usually equipped with an oil guide device at the bottom of the air duct. The oil guide device is directly installed at the bottom of the air duct without direct contact with the inner wall of the air duct. The oil droplets formed on the inner wall of the air duct cannot be guided well, and will directly drop on the surface of the cooktop, and thicker and thicker oil dirt is easy to accumulate on the inner wall of the air duct. In addition, the existing oil guiding device is usually far away from the oil receiving device, so not only may small oil droplets splash out from the inside of the air duct at any ti...
