Embodiment Construction
[0026] to combine figure 1 and figure 2 shown. The present invention proposes an oil fume separation device, comprising: a volute 1 with an air duct 13 inside, an air outlet 11 is provided at one end of the volute 1, and mounting holes 12 are provided on two opposite sides of the volute 1; The wind wheel 2 and the motor 4 in the hole 12, so the wind wheel 2 and the motor 4 are all located in the volute 1.
[0027] further combined image 3 and Figure 4 shown. The motor 4 is fixed by the motor bracket 3 . The motor support 3 includes a fixed ring 31, a mounting ring 32 and a connecting piece 33 connected between the fixed ring 31 and the mounting ring 32. The size of the fixing ring 31 is larger than that of the mounting ring 32, and the mounting ring is arranged on the mounting ring 31. and the fixed ring 31 is fixed on the volute 1, the mounting ring 32 is arranged in the first end of the central axis hole 20 of the wind wheel 2, the motor 4 is fixed on the mounting r...

The invention discloses a cooking fume separation device and a range hood. The cooking fume separation device comprises a volute, a wind wheel and a motor, wherein a wind guiding cover is arranged ina central shaft hole in the wind wheel; the wind guiding cover comprises a cover body fixing part which is fixedly arranged on the wind wheel, a cover body connecting part which is located in the central shaft hole and a plurality of wind guiding pieces; a rotating shaft connecting groove is formed in the middle part of the cover body connecting part; a rotating shaft of the motor is fixedly arranged in the rotating shaft connecting groove; the tail ends, which are close to the wind guiding cover, of blades of the wind wheel are set to be first blade ends, and the tail ends, which are close toa motor support, of the blades of the wind wheel are set to be second blade ends; the size or the surface area of the first blade ends is greater than the size or the surface area of the second bladeends. The cooking fume separation device disclosed by the invention is simple in structure and lower in implementation cost, a part of cooking fume mixed air can be guided to the second blade end through the wind guiding cover, and the effect of separating the cooking fume by all parts of the blade of the wind wheel can be relatively uniform, so that the whole cooking fume separation efficiency can be increased, and the working stability and the reliability of the cooking fume separation device are increased.
Description
technical field [0001] The invention relates to household appliances, in particular to an oil fume separation device and a range hood. Background technique [0002] Chinese patent application CN 2017211098619 discloses a volute fan for range hoods, which includes a volute, a centrifugal fan is provided inside the volute, an axial air inlet is provided on one side of the volute, and the wind The wheel seat is installed in the volute through the axial air inlet. The centrifugal fan includes a motor and a wind wheel seat. The edge of the wind wheel seat is provided with a plurality of blades at equal intervals. The motor is installed in the volute through the motor installation port. Inside, the motor is driven and connected to the wind wheel seat, and a vortex-shaped oil fume air duct is arranged inside the volute, and the size of the oil fume air duct gradually increases toward the radial air outlet. The technical solution is to install the wind wheel and the motor in the vo...
