Abstract

The invention discloses a fan system, which includes a volute and an impeller arranged in the volute, and an air inlet is formed on the volute, and is characterized in that: a Guide the airflow into the air inlet. When the air outlet of the volute is facing upwards, take a point on the axis of the impeller as the first center, and establish a coordinate system with the first center as the origin. In this coordinate system , take the horizontal line passing through the first center as the X-axis, take the vertical line passing through the first center as the Y-axis, and the X-axis takes the side opposite to the air outlet of the volute as the positive direction, and the Y-axis takes the first center upwards as Forward, the deflector is located in the second quadrant of the coordinate system. Also disclosed is a range hood applied with the fan system and a control method for the range hood.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a fan system, a range hood using the fan system, 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] Existing range hoods, as disclosed in Chinese Patent Application No. 201610283257.1, in...
