A control method for preventing side wind of range hood

Abstract

The invention discloses a sidewind prevention control method for a range hood, which is characterized in that: taking the range hood as the center, a first area and a second area around the range hood are divided, and the first area surrounds the range hood , the second area is surrounded by the first area; according to the above-mentioned divided areas, the control method includes the following steps: 1) cooking starts, the range hood is turned on, the initial gear position of the range hood, the range hood The initial weight of the pot placed on the stove below g 0 and the initial concentration of oil fume n 0 ; 2) At this time, the number of people in the kitchen is m, judge whether m≥2 is established, if yes, go to step 3), if not, go to step 4); 3) At this time, the number of people in the first area is m', Judging whether m'≥1 is true, if yes, go to step 5), if not, go to step 4); 4) perform single person anti-crosswind adjustment mode; 5) perform multi-person anti-crosswind adjustment mode.

Description

technical field [0001] The invention relates to a lampblack purifying device, in particular to a method for controlling crosswind prevention of a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. 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, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] When the range hood is turned on and running, if the operator moves around to add vegetables / water / seasonings during coo...

AI Technical Summary

Problems solved by technology

[0005] 1) Using wind speed sensor or wind pressure detection, there is hysteresis;

[0006] 2) The anti-crosswind technology without hysteresis detects the movement speed of the operator, but it lacks consideration of the interference caused by the movement of other personnel;

[0007] 3) No hysteresis The existing anti-sidewind technology detects the movement speed of the operator, but lacks the identification of the movement situation: a) the impact of moving left and right at the same speed is much greater than that of moving forward and backward; b) the characteristic length of a person does not change, but There are situations such as holding pot lids and seasonings, which form crosswinds and cause smoke to escape
