Cooking fume purification device and energy-saving control method thereof

Abstract

The invention discloses a cooking fume purification device. The cooking fume purification device comprises a cooking fume collection cover, a box body located above the cooking fume collection cover,a draught fan arranged in the box body, and a rotary purification module arranged on a cooking fume passage. The draught fan comprises a first draught fan body and a second draught fan, wherein the first draught fan body and the second draught body are arranged side by side in a left and right manner. The cooking fume purification device is characterized in that part of the purification module corresponds to the first draught fan body, part of the purification module corresponds to the second draught fan body, the cooking fume purification device further comprises a cooking fume sensor module,and the cooking fume sensor module is used for having control over the draught fan bodies and the gears of the purification module by monitoring the concentration of cooking fume. The invention further discloses an energy-saving control method of the cooking fume purification device.

Description

technical field [0001] The invention relates to the field of oil fume purification, in particular to an oil fume purification device and an energy-saving control method for the oil fume purification device. Background technique [0002] Due to the unique characteristics of Chinese cooking, the amount of oily smoke is very large. In order to improve the effect of oily smoke and meet the requirements of laws and regulations related to environmental protection, most catering units use lengthy flues and pass them on the roof or other away from residential areas. Place a high-power fan in the position to discharge the oil fume. However, after long-term use, a large amount of oil will accumulate inside the range hood and the air duct, which will cause performance degradation and poor effect of oil absorption. In practical applications, there are often large fans with small equipment ( The flue gas flow rate is too fast and the residence time is short, resulting in a decrease in pu...

AI Technical Summary

Problems solved by technology

[0004] (1) Increase the diameter of the air duct, limited by the space, the structure of the air duct is complex, it occupies a large area, and the effect is quite limited;

[0005] (2) Reduce the power of the exhaust fan and reduce the wind speed. When the amount of oil fume is large, the effect of oil fume absorption is reduced, resulting in more losses than gains;

[0006] (3) Both methods are difficult to solve the problem of large emission noise and nuisance to the people

[0008] However, the commonly used cooktops usually have two cookers, and the above-mentioned prior art cannot solve the problem of how to intelligently regulate the cookers according to the actual use of the cookers when they are used at the same time.
