A kind of intelligent control method of range hood

Abstract

The invention relates to an intelligent control method of a range hood. The range hood comprises a fan and a main controller, wherein the main controller controls the fan to run at different rotational speeds, and the fan has operating gears of different rotational speed ranges, including at least the following gears with sequentially increasing rotational speed: a first rotational speed range gear, a second rotational speed range gear, and a third rotational speed range gear. The control method comprises an intelligent cooking program; the range hood receives a user instruction to perform intelligent cooking program and runs at the gears one by one with different rotational speeds from low to high, and prescribed running time is executed for different rotational speed range gears; and after the fan runs at the gears one by one with different rotational speeds from low to high, the fan current is detected, and the operating gear of the fan is controlled according to the fan current. According to the control method, the operation process of the range hood is more smooth and natural, thereby improving the using experience of the user, and each gear matches the characteristics of the oil fume generated during cooking, which is more energy-saving and power-saving.

Description

technical field [0001] The invention relates to the field of kitchen household appliances, in particular to an intelligent control method for a range hood. Background technique [0002] Existing common range hoods are usually set with different working gears, such as low, middle or high gear. The range hood is provided with buttons matching the aforementioned gears, and each button corresponds to a corresponding gear. The rotation speed of the corresponding gear is executed by the fixed 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. It is required to actively select the fan operation gear, 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, The user will look...

[0002] Existing common range hoods are usually set with different working gears, such as low, middle or high gear. The range hood is provided with buttons matching the aforementioned gears, and each button corresponds to a corresponding gear. The rotation speed of the corresponding gear is executed by the fixed 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. It is required to actively select the fan operation gear, 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, The user will look up to see if it is running at the highest gear, and then choose to keep the fan running continuously at this gear. For convenience, most users directly select the highest gear of the range hood, so that the range hood will keep running every time it is started. In this gear, to speed up the smoke exhaust and reduce the operation of the range hood, in addition to using a 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, and the use of the range hood The feeling is low; and when the cooking is over, since the remaining smoke has not been exhausted, although the concentration of cooking fume is not high at this time, the hood still needs to continue to exhaust the smoke for a period of time. If it continues to operate at a high level at this time, the noise will be louder. And power consumption, if the user thinks about it, he may choose to switch to a low gear and continue to exhaust smoke

Therefore, in the existing range hood, the operating gear of the fan is highly dependent on the user's selection, and the user needs to spend more energy to pay attention to the concentration of the environmental oil fume during the cooking process.
