Abstract

The invention discloses an extractor hood. The extractor hood comprises an air inflow assembly, a smoke collecting assembly and a box body; a power device is arranged in the box body; the air inflow assembly comprises a first shell and an air inlet formed in the front side of the first shell; the top of the first shell is provided with an opening so that communicating with the interior of the boxbody can be achieved; the smoke collecting assembly comprises a second shell and a smoke baffle arranged on the front side of the second shell; the first shell can rise and fall relative to the secondshell, and the top of the second shell is fixed to the box body; the air inflow assembly can be in a closed state in which the first shell retracts into the second shell, or in an open state in whichat least part of an air inlet in the first shell is exposed out of the position below the second shell. The invention further discloses a control method of the extractor hood. Compared with the priorart, the extractor hood has the beneficial effects that application to cookware in different heights is achieved, the lifting stroke is short, lifting is stable, and lampblack can be fast sucked in conveniently; and when the smoke baffle and the air inlet are matched, the size of the smoke baffle is selected more flexibly, and negative pressure distribution of inflow is better adjusted.

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] Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely use...
