Fuzzy intelligent switch device and fuzzy intelligent speed change control method applied to range hood

Abstract

The invention discloses a fuzzy intelligent switch device and a fuzzy intelligent speed change control method applied to a range hood. The fuzzy intelligent switch device comprises a fuzzy controller, an ionic smoke sensor, a current regulator, a speed change regulator, a warning module, a power inverter and a PMU power management unit; the power inverter is connected with the fuzzy controller, the warning module, the current regulator, the speed change regulator and the ionic smoke sensor through the PMU power management unit; the ionic smoke sensor is used for sensing smoke, transforming the information into a voltage value and sending to the fuzzy controller; the fuzzy controller is used for driving the current regulator to control the current in a circuit; the speed change regulator is used for changing the power of a motor of the range hood to realize intelligent speed regulation; and the warning module runs automatically when the smoke concentration is too high. The device disclosed by the invention can realize intelligent speed regulation of the range hood in environments different in smoke concentration, can also realize safety alarming and reminding when the smoke concentration is relatively high, can prevent human body injuries caused by high-concentration smoke and inconveniences caused by frequent start and stop of the range hood in daily use, and can also improve the working performances of the range hood.

Description

Technical field [0001] The invention relates to the research field of a range hood, in particular to a fuzzy intelligent switch device and a fuzzy intelligent variable speed control method for the range hood. Background technique [0002] Since the 21st century, with the development of science and technology, the range hood technology has become more and more perfect. The exhaust fan of the range hood is a simple mechanism directly connected to the motor. The concentration of oil fume in the air allows the range hood to achieve better results by changing the motor speed. Improve the air quality, so as to better purify the air in the surrounding working environment. General range hoods are manually switched and adjusted speed, which has a certain practicality. In addition, because of its simple structure and good mechanical stability, it is low in cost and high in cost performance. The initial main application area was in the home kitchen. In recent years, with the continuous u...

Problems solved by technology

When people who work all day come home, it is inevitable to use cooking fumes during the cooking process. Even if they did not forget to turn on the range hood during the process, a series of problems such as speed regulation must be considered, which is time-consuming and laborious but cannot be ignored. , otherwise there will be unnecessary energy loss and waste, etc.

If you forget to close the natural gas valve in family life, it will naturally cause certain air pollution, and in severe cases, there will be potential dangers such as explosions.

Most of the existing range hoods are only manual or simply fixed and automatic, and cannot perform real-time self-speed adjustment and alarm prompts under different oil fume concentrations or complex surrounding environments. Loss and time-consuming, what's more, it may endanger personal health or safety

Nowadays, some common range hoods on the market do not have or do not fully have this function in this environment, and because of other factors, they cannot be applied to range hoods
