Range hood and control method thereof

Abstract

The range hood comprises a hollow box body and a fan system, the box body comprises a left side plate and a right side plate, and the range hood is characterized in that a first air inlet is formed in the left side plate, a second air inlet is formed in the right side plate, and the fan system is arranged in the box body; the two fan systems are arranged on the left side and the right side to form parallel double fans, each fan system is provided with a fan air inlet, the fan air inlet of the fan system located on the left side faces the first air inlet in the left side plate, and the fan air inlet of the fan system located on the right side faces the second air inlet in the right side plate. The invention further discloses a control method of the range hood. Compared with the prior art, the kitchen range has the advantages that the air inlets are directly formed in the left side and the right side of the box body, so that the air inlets can directly face the position above the center of the kitchen range, the fan system adopts parallel double fans, the air inlets of the fans directly face the air inlets of the box body, and negative pressure on the two sides is distributed in a concentrated mode.

Description

technical field [0001] The invention relates to an oil fume purification device, in particular to a range hood, and a control method of the range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern homes. The range hood uses the principle of fluid dynamics to work. The centrifugal fan installed inside the range hood sucks and discharges the oil fume, and uses the filter screen 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. After being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Range hoods are usually divided into top suction, side suction and low suction. The top suction range hood adopts the principle ...

AI Technical Summary

Problems solved by technology

The way to increase the air volume will bring noise and affect the indoor thermal balance and other problems: the bottom row type needs to destroy the countertop and re-drill holes in the public flue, which is affected by the upper and lower floors. Applicable, in addition, it violates the law of upward rising of oil fume, and more extra work is needed, which wastes energy; the increase of air volume brings noise and affects indoor heat balance and other problems
