If the user needs to return to obtain the height of the user, the operation similar to the embodiment is executed, and the opening and closing angle of the smoke guide plate is adjusted by re-matching angle data. If not, the user directly returns to obtain the mode selection signal, namely the user selects an adjusting mode to realize the adjustment operation of the opening and closing angle of the smoke guide plate. It will be appreciated that the manner in which the control means determines whether the user's height needs to be redetected is not exclusive and, in one embodiment, may also be implemented by determining whether an instruction sent by the user using a virtual key or a mechanical key has been received.

In one embodiment, when the opening and closing angle of the smoke guide plate is adjusted to meet the user requirement according to the size adjusting instruction sent by the user, or when the angle data obtained by matching in the preset height database meets the user requirement, the method further comprises the following steps: judging whether relevant parameters of the opening and closing angle of the current smoke guide plate need to be stored or not; if yes, saving the related parameters of the opening and closing angle of the current smoke guide plate; if not, executing the step of controlling the starting operation of the range hood.

Specifically, please refer to fig. 5 in combination, the control device adopts manual adjustment, and adjusts the opening and closing angle of the smoke guide plate to meet the user requirement according to the size adjustment instruction sent by the user, or the control device adopts automatic adjustment, and after the angle data meeting the user requirement is matched according to the height of the user, the control device can also carry out storage operation according to the angle data meeting the user requirement, so that the control device can directly select the angle data with the corresponding size in the angle selection mode. At this time, the control device firstly determines whether the relevant parameters of the opening and closing angle of the current smoke guide plate need to be stored, and specifically, the control device prompts a user whether the relevant parameters need to be stored through a touch display screen of the control device or other information prompting devices. If the user feeds back an instruction to be stored within a preset time length, the control device stores relevant parameters of the opening and closing angle of the smoke guide plate; if the storage instruction is not received within the preset time or the non-storage instruction sent by the user is received, the control device does not store the relevant parameters of the opening and closing angle of the smoke guide plate, and the opening and closing angle of the smoke guide plate is adjusted only according to the angle data obtained by current analysis, and the range hood is started. It can be understood that the manner of determining whether to store the relevant parameters of the opening and closing angle of the current smoke guide plate by the control device is not exclusive, and in one embodiment, the determination may also be performed by determining whether to receive an instruction sent by a user through a virtual key or a mechanical key.
