Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of kitchen appliances, specifically relates to an extractor hood. BACKGROUND

[0002] The existing extractor hood relies on the operation of the internal fan system to form a negative pressure area, and the oil fume flow in the kitchen is discharged outdoors through the extractor hood under the action of atmospheric pressure. In order to avoid oil fume escape, a movable smoke baffle is generally arranged at the smoke inlet of the extractor hood, specifically as the Chinese invention patent application "Smoke baffle driving system, smoke baffle driving method, extractor hood and storage medium" with the application number 202310804283.4 and the application publication number CN116734301A, the smoke baffle driving system is connected with the smoke baffle and includes a motor, a transmission mechanism connected between the motor and the smoke baffle and capable of converting the rotating action of the motor into the swinging action of the smoke baffle, and a hydraulic system connected with the transmission mechanism and used for providing resistance to the transmission mechanism to adjust the driving speed of the smoke baffle.

[0003] The design of the smoke baffle can effectively intercept the rising oil fume and reduce the risk of oil fume escape, but at the same time, the existing oil cup is usually installed at the bottom of the extractor hood, the movement of the smoke baffle is a rotating process, and there is a risk of collision with the oil cup during the opening and closing process of the smoke baffle, so a certain gap is left between the oil cup and the smoke baffle during the design to avoid interference. However, after the extractor hood is used for a period of time, oil stains will condense on the surface of the smoke baffle, and the existence of the gap makes the oil stains on the smoke baffle unable to flow into the oil cup and drop onto the cooking bench, thereby affecting the use experience of the user.
