Control method for blast volume of extractor hood and extractor hood with blast volume set by user

Abstract

The invention discloses a control method for the blast volume of an extractor hood. The control method is characterized in that the operating times of the high gear, medium gear and low gear of the extractor hood are set according to the cooking habits of a user as well as the amount of oil fume generated in the cooking process, namely the changing curve of the oil fume generated in the cooking process, the user adjusts the working times of the three gears according to requirements, after the extractor hood is started, and the working time of the whole extractor hood each time is T, specifically, T is the sum of T<high gear>,T<medium gear> and T<low gear>, that is, after being started, the whole extractor hood operates at the high gear for a certain period of time, is converted to the medium gear automatically and then is converted to the low gear after operating at the medium gear for a certain period of time; and after setting is completed, the pattern is memorized and preserved according to the cooking habits of the user and can be started directly next time without resetting. The control method can meet requirements of different users and achieve energy-saving, environment-friendly and comfort user experience.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to the control technology of the air volume of the range hood. Background technique [0002] The range hoods currently on the market are controlled by the high, medium and low gear keys, which are constant and cannot adjust the air volume according to the change of the oil fume during cooking. The oil fume cannot be fully discharged in time, the energy consumption is too high for a long time with a large air volume, the noise is high, and the user experience is poor. [0003] So people have thought of various ways to control the air volume of range hoods, such as the patent title is the automatic control method of the mode of controlling the air volume of range hoods and range hoods (CN201210319065.3), and the invention patent whose publication (announcement) number is CN103672995B The application includes the following steps: obtaining a library of standard working conditions;...
