Embodiment Construction
[0030] 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.
[0031] 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 ring...

The invention discloses an oil smoke separating device, a range hood and oil smoke purifying equipment. The oil smoke separating device comprises a volute, a wind wheel and a motor; a wind guide coveris arranged in a central shaft hole of the wind wheel, and the wind guide cover comprises a cover body fixing part fixed to the wind wheel, a cover body connecting part positioned in the central shaft hole and a plurality of wind guide sheets, wherein a rotating shaft connecting groove is formed in the middle of the cover body connecting part, and a rotating shaft of the motor is fixedly arrangedin the rotating shaft connecting groove; and the included angles of 5 degrees to 45 degrees are formed between wind wheel blades and the central axis of the wind wheel, and the size or surface area ratio of the first blade end of the wind wheel blades is larger than the size or surface area of the second blade end. According to the oil smoke separating device, the structure is simple, and the realization cost is low; and part of oil smoke mixed air is guided to the second blade end through the wind guide cover, so that the oil smoke separation effect of each part of the wind wheel blades is relatively uniform, so that the overall oil smoke separation efficiency is improved, and the working stability and reliability of the oil smoke separating device are improved.
Description
technical field [0001] The invention relates to household appliances, in particular to an oil fume separation device, a range hood and oil fume purification equipment. Background technique [0002] Chinese patent application CN2017211098619 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 wheel The 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 multiple blades at equal intervals, and the motor is installed in the volute through the motor installation port. , the motor is drivingly 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 ...
