Problems solved by technology

[0006] In the above-mentioned prior art, the automatic control method is to compare the difference between the oil fume image and the smoke-free background image through the pressure or the concentration of the oil fume, and then increase the speed for adsorption after the oil fume diffuses out, which is a hysteresis control method. , the user experience is poor; in addition, the control method of image recognition is easily affected by ambient light, and in the environment of oily smoke for a long time, it is easy to fail, and the accuracy is not high, which is prone to misjudgment

Abstract

The invention discloses a range hood, which includes a range hood body and a monitoring device, and is characterized in that: the monitoring device includes a first distance measuring sensor and a second distance measuring sensor arranged on the range hood body, The position of the first distance measuring sensor is used to correspond to the center of the bottom of the pan on the stove below the range hood, and the position of the second distance measuring sensor is used to correspond to the edge of the pan. Also disclosed is a control method for the above range hood. Use two ranging sensors to judge whether there is a pot cover or food into the pot at multiple points, so as to judge whether there is oil fume, and adjust the speed of the fan in advance before the oil fume is generated, which plays a preventive role and improves It improves the user's cooking experience and solves the problem of hysteresis adsorption of oil fume.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a control method for a cooking fume machine. Background technique [0002] The range hood has become one of the indispensable kitchen appliances in modern families. It is installed above the kitchen stove, which can quickly suck away the waste burned by the stove and the harmful oil fume generated during the cooking process, and discharge it outside, reducing the Pollution, air purification, and anti-virus, anti-explosion safety guarantee function. [0003] The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, an...
