Double-air intake extractor hood and control method thereof

Abstract

The invention discloses a double-air intake extractor hood and a control method thereof. The double-air intake extractor hood comprises a fan cover, a smoke collection hood and a centrifugal fan. Theleft and right sides of the centrifugal fan respectively form a left air inlet channel and a right air inlet channel. The bottom of the smoke collection hood is provided with a left air inlet and a right air inlet. The middle of the smoke collection hood is provided with a movable partition plate capable of deflecting left and right. In a non-deflecting state of the movable partition plate, the left air inlet channel and the right air inlet channel are isolated. In a left deflecting state of the movable partition plate at the largest angle, the left air inlet channel and the right air inlet channel are isolated from the left air inlet. In a right deflecting state of the movable partition plate at the largest angle, the left air inlet channel and the right air inlet channel are isolated from the right air inlet. The movable partition plate capable of deflecting left and right is arranged at the middle of the smoke collection hood and can carry out corresponding deflecting adjustment according to the amounts of smoke in left and right sides so that negative pressure suction forces in left and right sides can be intelligently controlled and the oil smoke suction effects are improved effectively.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood with double air inlets and a control method thereof. Background technique [0002] Common household stoves usually have two burners on the left and right. During the cooking process, users sometimes only use one side of the burner, and sometimes use both sides at the same time. If the user only uses the stove on the left side to stir-fry, or uses the left side to stir-fry and the right side to steam rice, then for the range hood, the concentration and particles of oil fume on the left side are bound to be much larger than those on the right side. , and the performance of the range hood has been determined after the product leaves the factory, and the negative pressure suction on the left and right sides of the range hood cannot be automatically adjusted according to the amount of fumes on the left and right sides, that is, the negative pressure suction on the right cannot be distribut...

Problems solved by technology

If the user only uses the stove on the left side to stir-fry, or uses the left side to stir-fry and the right side to steam rice, then for the range hood, the concentration and particles of oil fume on the left side are bound to be much larger than those on the right side. , and the performance of the range hood has been determined after the product leaves the factory, and the negative pressure suction on the left and right sides of the range hood cannot be automatically adjusted according to the amount of fumes on the left and right sides, that is, the negative pressure suction on the right cannot be distributed to The negative pressure suction on the left side cannot improve the effect of oil suction

Various double-inlet range hoods with different structures have been disclosed in the prior art, such as "A Double-Inlet Range Hood" disclosed in the Chinese invention patent application with application number 201610873821.5 (application publication number is CN 106439965A) , the double-inlet range hood includes a smoke collection hood, an air inlet is opened on the smoke collection hood, a smoke guide plate is provided at a position corresponding to the air inlet below the smoke collection hood, and the gap between the edge of the smoke guide plate and the smoke collection hood An outer air inlet is formed, and an opening is opened on the smoke guide plate to form an inner air inlet. Although, this double-inlet range hood combines the advantages of the middle air inlet and the surrounding air inlet, the inner air inlet ensures the concentrated negative pressure under the smoke collecting hood Most of the range hood enters the range hood from the inner air inlet, and the outer air inlet expands the negative pressure area, and the remaining uncaptured oil fume escapes around the smoke deflector and enters the range hood by the outer air inlet, thus greatly The range hood has improved the range hood's range hood suction effect, but it cannot adjust the negative pressure suction of the two air inlets according to the range hood on the left and right sides, and the degree of intelligence is low
