Range hood and control method thereof

Abstract

The invention discloses a range hood, which comprises a smoke collecting hood, a front smoke baffle, a first side smoke baffle and a second side smoke baffle, the front smoke baffle is rotatably arranged under the front side of the smoke collecting hood , and can be in the first position extending horizontally and the second position extending longitudinally; the first side smoke baffle and the second side smoke baffle are respectively rotatably arranged at the left and right ends of the front smoke baffle, and can be in the The third position extending in the same direction as the front smoke baffle and the fourth position extending longitudinally under the left and right sides of the smoke collecting hood are respectively flipped opposite to the front smoke baffle. Also disclosed is a control method for the above range hood. Compared with the prior art, the present invention has the advantages of: by setting the smoke baffle on three sides and adopting the plan of step-by-step folding, the purpose of protecting three sides and reducing the area and time for handling is achieved. On the one hand, step-by-step folding can make the appearance of the product On the premise of ensuring, the smoke collection effect is improved. On the other hand, the folded structure reduces the number of gaps and dead corners, and greatly reduces the maintenance time.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a range hood and a control method for the 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. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used due to ...

Problems solved by technology

However, if the baffles on both sides and the front side are installed at the same time, due to structural interference, they cannot be folded inward when not in use, which will bring inconvenience to use and affect the aesthetics of the product. There is a gap between the fume collecting hood and oil stains, and the position of the gap is easy to form a vortex of oil fume. The existence of this vortex will intensify the adhesion of oil stains, resulting in the formation of dead ends. In addition, the smoke baffles on each side are controlled separately, and a cleaning dead angle will be added on the left and right sides, and the cleaning workload is more than three times that of the single front side. The user will increase the difficulty of cleaning, the user's cleaning experience is extremely poor, and three storage areas will be formed, the structure is complicated, and it will also affect the appearance of the product
