Problems solved by technology

[0004] However, the negative pressure distribution of this kind of range hood cannot be adjusted, and it cannot effectively deal with the situation of double-use single-use and external flow field changes, etc., and the range hood effect is not good; the oil on the windshield needs to be cleaned frequently, otherwise it is easy to drip fall on the stove

Abstract

The invention discloses a range hood, which comprises a casing, a panel arranged at the opening of the front side of the casing, and a smoke baffle assembly, the panel is provided with an air inlet, and the feature is that the smoke baffle assembly It includes a smoke baffle that can open or close the air inlet, and can swing left and right and up and down to adjust the gap with the air inlet. When the air inlet is opened, a ring suction is formed between the smoke baffle and the air inlet. Also disclosed is a control method for the range hood as described above. Compared with the prior art, the present invention has the advantages that: by setting the smoke baffle with two rotational degrees of freedom and one translational freedom, a ring suction opening is formed between the smoke baffle and the panel, and through the smoke baffle Position control, the ring suction gap can be adjusted as a whole, or independently from left to right or up and down, so as to control the negative pressure distribution of the air inlet at different positions to cope with complex user environments.

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. [0003] The existing side-suction range hoods often adopt ring suction in order to improve the effect of the range hood and reduce ...
