A control method for range hood detection fan

Abstract

The invention relates to a range hood detection draught fan control method. A range hood comprises an exhaust motor and a master controller. The exhaust motor is provided with a plurality of rotation speed sections. The master controller controls the exhaust motor to run under the different rotation speed sections. The range hood is further provided with an air quality detection device. A detection draught fan is arranged in the air quality detection device. The control method comprises the steps that the master controller receives an air quality detection instruction; the detection draught fan is started, and the air quality detection device collects the gas detection value in the current environment; the master controller controls the exhaust motor to execute the corresponding rotation speed section according to the gas detection value; the detection draught fan executes different work states according to the rotation speed section where the exhaust motor is located till air quality detection is over, and the detection draught fan stops running. According to the control method, the work state of the detection draught fan in the air quality detection device is controlled according to the rotation speed section where the exhaust motor is located, and accuracy of the gas detection value is improved.

Description

Technical field [0001] The invention relates to the field of kitchen household appliances, in particular to a method for controlling a fan for detecting a range hood. Background technique [0002] The exhaust motors of the existing common range hoods are usually set with different working gears, such as low, middle or high gears. The range hoods are equipped with buttons matching the aforementioned gears, and each button corresponds to a corresponding gear. The speed of the corresponding gear is executed according to the user's selected button, and the gear executed under each button is stable and unique. Unless the user selects other buttons, the range hood fan will switch gears to run. The advantage of this method is that the user The fan operating gear can be actively selected according to the smoke exhaust demand, and the gear is intuitive and stable during operation, but in the actual cooking process, the user does not have the energy to pay attention to the air quality and ...

[0002] Exhaust motors of common range hoods are usually set with different working gears, such as low gear, middle gear or high gear. The range hood is provided with buttons matching the aforementioned gears, and each button corresponds to a corresponding gear. According to the selected button of the user, the speed of the corresponding gear is executed, and the gear executed under each button is stable and unique. Unless the user selects another button, the range hood fan will switch gears to run. The advantage of this method is that the user You can actively select the fan operation gear according to the smoke exhaust requirements, and the gear operation process is intuitive and stable, but in the actual cooking process, the user does not have the energy to pay attention to the air quality and switch gears in real time, most of the time only when the concentration of oily smoke is very high Only when the fan is in the highest gear, the user will look up to see if it is running at the highest gear, and then choose to keep the fan running at this gear. For convenience, most users directly select the highest gear of the range hood, so that the range hood This gear is maintained every time you start to speed up the smoke exhaust and reduce the operation of the range hood. In this way, in addition to using high-grade operation to consume power and energy when the lampblack is generated less, and the hood is directly started at a high-grade level, the noise is relatively large. , the experience of using the range hood is poor; and when the cooking is over, since the residual smoke has not been exhausted, although the concentration of kitchen fumes is not high at this time, the hood still needs to continue to exhaust smoke for a period of time. If it continues to operate at a high level, then The noise is loud, and the power consumption is high. If the user thinks about it, he may choose to switch to a low gear and continue to exhaust smoke. However, in most cases, after cooking, the user will let the exhaust motor continue to run for a period of time before turning it off.

Therefore, in the existing range hood, the operating gear of the fan is highly dependent on the user's choice, and the user needs to spend more energy to pay attention to the concentration of the environmental oil fume during the cooking process, and the range hood cannot adjust the exhaust air by itself by detecting the air quality. Motor gear, and there is no operation control method for the detection device itself in the industry
