[0063] In one embodiment, S200 includes:

[0064] S201, according to the simulated flow information of the duct airflow, selecting the simulated flow direction of the duct airflow and the middle cross-section duct section under the simulated flow state of the duct airflow, and obtaining a velocity cloud diagram of the middle cross-section duct section;

The air flows out of the outlet grille in an upward manner; the air flow speeds at the inlet grille and outlet grille are 2-3m / s and 5-7m / s respectively; in the case of complete upper and lower wind wheel assemblies, the airflows generated by the upper and lower wind wheels will impact and mix with each other, and make the performance of each component slightly lower than when the individual components are running; the outlet airflow direction can be changed by adjusting the air outlet height and layout position; under the influence of impeller rotation, air duct and impeller rear disc guidance and outlet height, the air flow will rotate upward and flow out of the outlet grille; there is an obvious vortex phenomenon near the impeller outlet grille, and the speed is not low. This is because there is a suddenly expanding airflow channel (circled with a square frame) from the impeller outlet to the air outlet; the airflow will flow into the box area under the guidance of the wind duct, and will cause pressure loss to a certain extent; and the outflowing high-speed airflow will drive the low-speed airflow at the edge of the sudden expansion section to flow and form a vortex, and cause a certain degree of noise increase; if the airflow needs to still flow upward, feasible improvement measures include: adjusting the inclination of the impeller rear disc and the matching motor fixing bracket, or increasing the distance between the air outlet and the impeller, and controlling the sudden expansion section within a more reasonable range; if the airflow needs to flow out nearly horizontally, the air outlet height and layout position should be adjusted.

[0082] The fan blade filter spacing parameters and the air inlet duct configuration are optimized. The intelligent optimization of the purifier duct components includes: optimizing the fan blade filter spacing parameters, the fan blade bottom distance from the filter required to produce the optimal negative pressure parameter distance H3 = 0.2d--0.6d; the wind wheel distance filter air inlet duct is consistent with the air flow trajectory to present a fluid trajectory type, and the air inlet duct configuration is optimized; through the intelligent optimization and adjustment of the duct airflow velocity, duct wall pressure, and airflow flow noise, the duct airflow velocity is balanced, the duct wall pressure is reduced, the airflow flow noise is reduced, and the purifier duct components are intelligently optimized.

[0083] The principle and effect of the above technical solution are as follows: S400 includes:

Therefore, although there is still a vortex phenomenon in this area, the speed is low and no significant pressure loss is caused; after adjusting the air outlet, the performance will be slightly improved because the airflow is no longer guided by the wind duct; but the wind wheel will be more exposed to the air outlet than before, so that the noise level will increase; it can be seen that the design of the air outlet height will obviously affect the outflow direction of the airflow and slightly affect the performance and noise. The appropriate air outlet height can be selected according to specific needs; if there are upper and lower components, selecting a horizontal air outlet method can reduce the mutual interference between the two components.

The air flows out of the outlet grille in an upward manner; the air flow speeds at the inlet grille and outlet grille are 2-3m / s and 5-7m / s respectively; in the case of complete upper and lower wind wheel assemblies, the airflows generated by the upper and lower wind wheels will impact and mix with each other, and make the performance of each component slightly lower than when the individual components are running; the outlet airflow direction can be changed by adjusting the air outlet height and layout position; under the influence of impeller rotation, air duct and impeller rear disc guidance and outlet height, the air flow will rotate upward and flow out of the outlet grille; there is an obvious vortex phenomenon near the impeller outlet grille, and the speed is not low. This is because there is a suddenly expanding airflow channel (circled with a square frame) from the impeller outlet to the air outlet; the airflow will flow into the box area under the guidance of the wind duct, and will cause pressure loss to a certain extent; and the outflowing high-speed airflow will drive the low-speed airflow at the edge of the sudden expansion section to flow and form a vortex, and cause a certain degree of noise increase; if the airflow needs to still flow upward, feasible improvement measures include: adjusting the inclination of the impeller rear disc and the matching motor fixing bracket, or increasing the distance between the air outlet and the impeller, and controlling the sudden expansion section within a more reasonable range; if the airflow needs to flow out nearly horizontally, the air outlet height and layout position should be adjusted.

[0119] The principle and effect of the above technical solution are: the fan blade parameter air duct configuration optimization module includes:

Therefore, although there is still a vortex phenomenon in this area, the speed is low and no significant pressure loss is caused; after adjusting the air outlet, the performance will be slightly improved because the airflow is no longer guided by the air duct; but the wind wheel will be more exposed to the air outlet than before, so that the noise level will increase; it can be seen that the air outlet height design will obviously affect the airflow outflow direction and slightly affect the performance and noise. The appropriate air outlet height can be selected according to specific needs; if there are upper and lower components, choosing a horizontal air outlet method can reduce the mutual interference between the two components.
