Abstract
The present disclosure provides a control method for a range hood and a range hood. The range hood includes a fan, and the control method includes: collecting a current operating state parameter of the fan; determining a current air duct parameter based on the current operating state parameter; and controlling operations of the fan based on the current air duct parameter and a predetermined control policy.
Claims6
A control method for a range hood, wherein the range hood comprises a fan, and the control method comprises:
- collecting a current operating state parameter of the fan;
- determining a current air duct parameter based on the current operating state parameter;
- and
- controlling operations of the fan based on the current air duct parameter and a predetermined control policy, comprising:
- determining a current air duct blockage state based on the current air duct parameter;
- increasing a rotational speed of the fan in accordance with a determination that the current air duct blockage state is a first blockage state;
- decreasing the rotational speed of the fan in accordance with a determination that the current air duct blockage state is a second blockage state;
- and
- controlling the fan to operate at a constant rotational speed in accordance with a determination that the current air duct blockage state is a third blockage state, the third blockage state being a zero air pressure state;
- wherein said controlling the operation of the fan based on current air duct parameters and the predetermined control policy comprises:
- determining a standard air duct parameter for a current gear based on the predetermined control policy;
- modifying the standard air duct parameter to obtain an actual air duct parameter;
- determining a target air volume based on the actual air duct parameter and the standard air duct parameter for the current gear;
- and
- adjusting the rotational speed of the fan based on the target air volume;
- wherein the standard air duct parameter comprises an air pressure and an air volume of the range hood,
- wherein the range hood comprises an oil fume detection component disposed on an outer wall of a check valve,
- wherein controlling operations of the fan based on the current air duct parameter and a predetermined control policy comprises:
- controlling the rotational speed of the fan based on an oil fume concentration detected by the oil fume detection component.
