  • Patent number: 11473782
    Abstract: The present invention discloses a contactless control device for a range hood and a control method thereof. The contactless control device comprises two sets of infrared gesture sensing devices disposed on the housing of the range hood, and a detected signal analysis device. Each set of infrared gesture sensing devices comprises one infrared receiving device and at least one infrared transmitting device. The distance L between two infrared receiving devices meets the following condition: H*tan(?)+H*tan(?)+W_min<L<H*tan(?)+H*tan(?)+W_max. It is unnecessary to control the user's gesture sensing distance according to the intensity of the infrared transmitted signals. In this way, it is convenient to adjust the intensity of the infrared transmitted signals, and the infrared receiving device can better detect infrared signals.
