Embodiment Construction
[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0021] The automatic opening and closing device is a device that includes a main body and a movable part, and the movable part can move between a first position close to the main body and a second position away from the main body under the drive of the driving part, wherein the movable part moves from the second position to the main body. The way the position moves to the first position may include that one end of the movable part rotates around the main body under the action of the driving part, such as Figur...

The invention provides a control method and device used for an automatic opening and closing device and a range hood. The automatic opening and closing device comprises a main body and a movable part;and the movable part is used for moving between a first position close to the main body and a second position away from the main body under driving of the driving part. The method comprises the stepsthat when a closing instruction is received, whether the current stay position of the movable part is the second position or not is judged; when the current stay position is not the second position,the movable part is controlled to move to the second position, and then move towards the first position according to the first moving speed; whether the movable part reaches the preset moving positionor not or whether the moving time of the movable part reaches the preset moving time or not is judged; and when the movable part reaches the preset moving position or when the moving time of the movable part reaches the preset moving time, the movable part is controlled to move to the first position according to the second moving speed, wherein the second moving speed is smaller than the first moving speed.
Description
technical field [0001] The invention relates to the field of home appliances, in particular to a control method and device for an automatic opening and closing device and a range hood. Background technique [0002] With the development of the economy, people have higher and higher requirements for the quality of life. For the convenience of use, automatic opening and closing devices are installed on many devices, such as range hoods. In order to reduce the storage space of the range hood and ensure the shape of the range hood It is beautiful, and the range hood is equipped with a smoke guide plate. When the range hood is working, the smoke guide plate is opened, and when it stops working, the smoke guide plate is closed. However, due to improper operation and use during the closing process of the smoke guide plate, there is a risk of pinching hands ; The existing method of preventing hand pinching in the closing process is to use the timing method to obtain the position of t...
