With reference to fig. 8 and 9, the wind wheel 2 adopts the whole structure of the prior art, and the invention only improves the structure of the wind wheel blades 21 of the wind wheel 2: the wind wheel blade 21 comprises a first blade 211 and a second blade 212 which are connected side by side, and the included angle between the first blade 211 and the second blade 212 is preferably an obtuse angle; the first blade 211 and the second blade 212 are integrally formed, and the first blade 211 and the second blade 212 may be disposed in a cambered surface (as shown in fig. 9); further, the end of the rotor blade 21 close to the wind scoops 5 is set as a first blade end 2101, the end of the rotor blade 21 close to the motor mount 3 is set as a second blade end 2102, and the size or surface area of the rotor blade 21 from the second blade end 2102 to the first blade end 2101 is gradually increased, that is, the size or surface area of the first blade end 2101 is larger than that of the second blade end 2102.
The working principle of the oil fume separation device provided by the invention is as follows: when the motor 4 rotates, the rotating shaft 41 drives the wind scooper 5 and the wind wheel 2 to synchronously rotate through the hood connecting part 52, so that negative pressure is formed below the wind scooper 5, and the oil smoke mixed air can enter the volute 1 through the wind scooper 5 due to the negative pressure; during the rotation of the wind scooper 5, the windward side plate 532 of the wind guide piece 53 strikes the oil smoke mixed air, so that the oil smoke mixed air is driven to move along the surface of the wind guide piece 53, and the oil smoke mixed air is guided to the wind wheel 2 along the surface of the wind guide side plate 533 of the wind guide piece 53; because the wind scooper 5 is arranged in the central shaft hole 20 of the wind wheel 2, the wind guide fins 53 can guide part of the oil-smoke mixed air to the second blade ends 2102 of the wind wheel blades 21, and the part of the oil-smoke mixed air forms airflow to flow through the surface of the motor 4 to cool the motor 4; the motor 4 drives the wind wheel 2 to rotate at a high speed, so that the wind guide pieces 53 of the wind guide cover 5 and the wind wheel blades 21 of the wind wheel 2 jointly participate in striking the oil smoke mixed air to realize oil smoke separation. Therefore, a large amount of oil-smoke mixed air can directly enter the first blade end 2101 of the wind wheel blade 21 in the wind wheel 2 under the action of negative pressure, and the oil-smoke separation can be carried out on most of the oil-smoke mixed air due to the large size or the large surface area of the first blade end 2101; according to the invention, the wind guide cover 5 is arranged on the wind wheel 2, on one hand, the wind guide cover 5 guides part of oil smoke mixed air to the second blade end 2102 of the wind wheel blade 21, so that the second blade end 2102 with a relatively small size or area participates in oil smoke separation of air with less oil smoke mixing opening, and the oil smoke separation effect of each part of the wind wheel blade 21 is relatively uniform, thereby improving the whole oil smoke separation efficiency, on the other hand, the wind guide cover 5 guides the oil smoke mixed air to form airflow for cooling the motor 4, thereby ensuring that the motor 4 can stably work, and further improving the working stability and reliability of the oil smoke separation device.
Furthermore, in order to prevent the oil smoke mixed air guided to the wind wheel blades 21 by the wind guide pieces 53 from flowing out from gaps among the connected wind wheel blades 21 in a laminar flow manner to cause a large oil smoke separation effect, the invention arranges an included angle of 5-45 degrees between the wind wheel blades 21 and the central axis of the wind wheel 2, thus, even if part of the oil smoke mixed air is guided to the wind wheel blades 21 by the wind guide pieces 53 in a laminar flow manner, because each wind wheel blade 21 is arranged in an included angle of 5-45 degrees, the oil smoke mixed air existing in the laminar flow manner can be beaten on different parts of the wind wheel blades 21 to be disordered, the oil smoke mixed air passes through the wind wheel 2 in a turbulent flow manner, and thus the wind wheel blades 21 are beaten in a rapid rotation process to realize oil smoke separation treatment, and the oil smoke separation effect is further improved.
In addition, the number N of the air guiding fins 53, the area S1 of the upper side surface of the air fin body 531 of each air guiding fin 53, and the area S2 of the upper side surface of the windward side plate 532 of each air guiding fin 53 should not be too large, because the result of multiplying N by S1 is larger than the area S0 of the upper side surface of the air guiding cover 5, which results in an excessively small gap path for the oil and smoke mixed air to pass through on the air guiding cover 5 and on the contrary blocks the oil and smoke mixed air, and the excessively large wind resistance caused by the excessively large S2 is not beneficial to the oil and smoke mixed air to flow to the wind wheel 2 through the air guiding cover 5, and cannot sufficiently guide the oil and smoke mixed air to the wind wheel 2 when the S2 is excessively. Therefore, the result of multiplying N by S1 is 5% -20% of the area S0 of the upper side surface of the wind scooper 5, wherein N is preferably a natural number not greater than 12, and the result of multiplying N by S2 is preferably 3% -10% of the total area S3 (i.e. the sum of the areas of the outer side surfaces of all the wind wheel blades 21) of the surfaces/outer side surfaces of all the wind wheel blades 21 participating in the oil smoke separation treatment.
And (3) comparison test: comparing a group A and a group B, wherein 2 range hoods adopting the CN 2017212123143 scheme are purchased from the market respectively; the oil smoke separation devices (wherein the total area of the upper side surface of the air guide cover 5 is S0=2800cm2, and the total area of all the wind wheel blades 21 participating in oil smoke separation treatment is S3=12760 cm 2) are assembled into the oil smoke exhaust ventilator according to the technical scheme of CN 2017212123143 by the test group C and the test group D; in the test group C, the number N =8 of the air deflectors 53 in the oil-smoke separation device, the rectangular air deflector body 531 is 20cm long and 2cm wide (S1=40 cm 2), and the rectangular windward side plate 532 is 20cm long and 3cm wide (S2=60cm 2), so that the result of multiplying N by S1 accounts for 11.4% of S0, and the result of multiplying N by S2 accounts for 3.76% of S3; in test group C, the number N =12 of air deflectors 53, the size of the rectangular air deflector body 531 was selected to be 20cm long and 1.5cm wide (S1=30 cm 2), and the size of the rectangular windward side plate 532 was selected to be 20cm long and 5cm wide (S2=100 cm 2), so that the result of multiplying N by S1 accounted for 12.9% of S0, and the result of multiplying N by S2 accounted for 9.4% of S3. The oil removal rate test was performed under the same environment for 10 minutes, 1 test result was obtained per minute, and the oil removal capacities of the control group a, the control group B, the test group C, and the test group D were 79.31%, 81.74%, 97.53%, and 99.17%, respectively, as the final test results, which were the arithmetic average of the 10 test results. Therefore, the oil smoke separating capacity of the oil smoke separating device provided by the invention is far stronger than that of the existing oil smoke separating device.
