电风扇及电风扇控制方法
摘要：
本发明涉及一种电风扇及电风扇控制方法。该电风扇包括红外感应器、风扇头、第一驱动单元、第二驱动单元及处理单元。该红外感应器用于感应该电风扇周围一预设范围内的人体。该处理单元分别与该红外感应器、该第一驱动单元及该第二驱动单元连接。该处理单元用于：通过该红外感应器侦测该预设范围内是否存在人体；在侦测到该预设范围内存在人体时控制该第一驱动单元驱动该风扇头摇摆以使该风扇头正对该人体；及控制该第二驱动单元驱动该风扇头的风叶转动。本案中的电风扇及电风扇控制方法能够侦测一预设范围内是否存在人体，并在侦测到该预设范围内存在人体时控制该风扇头摇摆以使该风扇头正对该人体，增加了用户受风的时间及提高了用户的体验感。
摘要（英）：

The invention relates to an electric fan and an electric fan control method. The electric fan comprises an infrared inductor, a fan head, a first drive unit, a second drive unit and a processing unit.The infrared inductor is used for inducting the human body within the preset range around the electric fan. The processing unit is connected with the infrared inductor, the first drive unit and the second drive unit. The processing unit is used for detecting whether the human body exists in the preset range or not through the infrared inductor. When it is detected that the human body exists in the preset range, the first drive unit drives the fan head to swing to enable the fan head to directly face the human body, and the second drive unit is controlled to drive blades of the fan head to rotate. According to the electric fan and the electric fan control method in the scheme, whether the human body exists in the preset range or not can be detected, when it is detected that the human bodyexists in the preset range, the fan head is controlled to swing to directly face the human body, time for receiving wind by users is prolonged, and experience of the users is improved.
