Central oil fume purification system and real-time automatic control mode thereof

Abstract

The present invention discloses a central oil fume purification system, which comprises a public flue channel, wherein kitchens in each layer are respectively provided with a connection pipe connected to the public flue channel, the upper end of the public flue channel is connected to an oil fume purifier and a fan in series, the kitchens in each layer are respectively provided with a fume collection cover, and the fume collection covers are connected to the public flue channel through the connection pipelines. The invention further discloses a real-time automatic control mode of the central oil fume purification system, wherein the wind sucking amount can be uniformly distributed by regulating the wind valve opening angles calculated through the formula in different layers. According to the present invention, the pressure in the public flue channel at the cooking peak stage can be eliminated, the fume discharging effect between the high floor and the lower floor can be uniformly distributed, and the fume returning and the odor mixing can be prevented.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a central lampblack purification system and a real-time automatic control method thereof. Background technique [0002] Existing high-rise residences are generally designed with a public flue, and the cooking fumes in the kitchen at the same position on each floor are discharged into the public flue through the range hood, and then enter the atmospheric environment through the exit of the public flue on the roof. Chinese patent document CN104566588A disclosed "a central purification system" on April 29, 2015, including oil fume collection pipes, purifiers, and fan pipes. The oil fume collection pipes, purifiers, and fan pipes are connected in sequence to form a whole. The firmware is installed on the shock absorber and the installation base, where one end of the oil fume connection pipe A in the oil fume collection pipe is connected to the oil fume outlet of the pu...

AI Technical Summary

Problems solved by technology

Therefore, the smoke exhaust effect of range hoods on high floors and low floors is very different, the effect is good on high floors, and the effect on low floors is poor

During the peak cooking period, each range hood actively exhausts smoke into the public flue through its own fan. The non-return valve of the machine is not closed tightly, the installation is poor, or the flue is cracked, etc., which will cause the oil fume in the flue to flow into the kitchen, which will have a negative impact on the kitchen environment.
