Range hood with blowing rate adjusted by user

Abstract

The invention discloses a range hood with a blowing rate adjusted by user. The range hood is characterized in that on the basis of cooking habits of a user and the amount of oil smoke generated during the cooking process namely the curve change of oil smoke generated during the cooking process, the operation time of different blowing rates (high speed, medium speed, and low speed) of the range hood is set. The operation time of three levels can be adjusted according to the needs of the user. One complete operation time is set to be T after the range hood is started. T= T(high speed)+T(medium speed)+T(low speed). After the range hood is started, the range hood operates in the high speed level for a while, then the range hood automatically turns to the medium speed level, and after the range hood operates in the medium speed level for a while, the range hood turns to the low speed level. After setting, the mode can be stored in memory according to the cooking habits of the user. Next time, after the range hood is started, the mode is directly called out without resetting. The range hood can meet the requirements of different users, and is energy-saving and environment-friendly, and the user experience is comfortable.

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;...
