7. The range hood with oil smoke partition according to claim 1, further comprising a filtering structure arranged outside the first air guiding structure and the second air guiding structure, wherein the filtering structure comprises a filter screen and/or an oil smoke separating screen.
8. A method of operating a range hood for a range hood according to any one of claims 1 to 7, comprising:
the first temperature sensing element and the second temperature sensing element sense the temperature of the area below the position of the first temperature sensing element and the second temperature sensing element respectively;
if only the first temperature sensing element senses that the temperature of the area below the position of the first temperature sensing element reaches a preset starting temperature threshold value, the control module starts the fan and controls the first air guide structure to enter an opening state so that air flow of the area below the position of the first air guide structure enters the cavity;
if only the second temperature sensing element senses that the temperature of the area below the position of the second temperature sensing element reaches a preset starting temperature threshold value, the control module starts the fan and controls the second air guide structure to enter an opening state so that air flow of the area below the position of the second air guide structure enters the cavity;
if the temperature of the area below the position where the first temperature sensing element and the second temperature sensing element are positioned reaches a preset starting temperature threshold value, the control module starts the fan and controls the first air guide structure and the second air guide structure to enter an opening state so that air flow of the area below the position where the first air guide structure and the second air guide structure are positioned enters the cavity;
the first temperature sensing element and the second temperature sensing element are detected by taking time T1 as a period, wherein T1 is more than or equal to 0.1 second.
9. The method of claim 8, wherein the temperature value-fan suction level mapping table is stored in the control device;
the control module adjusts the suction level of the fan according to the highest temperature value and the temperature value-fan suction level mapping table in the detection data of the first temperature sensing element and/or the second temperature sensing element.
10. The method according to claim 8, wherein if the first temperature sensing element senses that the temperature of the area below the first temperature sensing element reaches a preset closing temperature threshold, the control module controls the first air guiding structure to enter a closing state;
if the temperature of the area below the position where the second temperature sensing element is positioned is sensed to reach a preset closing temperature threshold value, the control module controls the second air guide structure to enter a closing state;
if the first temperature sensing element and the second temperature sensing element sense that the temperature of the area below the position of the first temperature sensing element and the second temperature sensing element reaches a preset closing temperature threshold value, the control module closes the fan and controls the first air guide structure and the second air guide structure to enter a closing state;
the first temperature sensing element and the second temperature sensing element are detected by taking time T2 as a period, wherein T2 is more than or equal to 0.1 second.
