Extractor hood and control method for opening and closing panel assembly

Abstract

The invention discloses an extractor hood and a control method for an opening and closing panel assembly. The extractor hood comprises the opening and closing panel assembly which comprises a drivingmotor, an opening and closing panel and a control device. The opening and closing panel is connected with the driving motor; and the control device is electrically connected with the driving motor. The control device is used for controlling the rotating direction and the work time of the driving motor so as to control the opening and closing panel to rotate and make the opening and closing panel kept at a minimum angle, a maximum angle or at least one angle between the minimum angle and the maximum angle; the work time of the driving motor is relevant to the angle of the opening and closing panel; and the rotating direction of the driving motor is relevant to the rotating direction of the opening and closing panel. According to the extractor hood, the control device is sued for controllingthe rotating direction and the work time of the driving motor so as to control the opening and closing angle of the opening and closing panel, it can be avoided that a limiting switch arranged in theopening and closing panel assembly is used, and therefore accurate control over the opening and closing angle of the opening and closing panel and multiple opening and closing angles of the opening and closing panel can be achieved. Meanwhile, the hardware cost of the extractor hood can also be reduced.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method for a range hood and an opening and closing panel assembly. Background technique [0002] In the related art, the side suction range hood has an opening and closing panel, and when the range hood is working, the opening and closing panel is opened to prevent the smoke from escaping. However, the opening and closing angle of the opening and closing panel often depends on the limit switch built in the motor, resulting in a limited range of opening and closing angles of the opening and closing panel, and the multi-angle control of opening and closing of the opening and closing panel cannot be performed. Contents of the invention [0003] Embodiments of the present invention provide a method for controlling a range hood and an opening and closing panel assembly. [0004] The range hood in the embodiment of the present invention includes an opening and...
