Gesture recognition method and circuit and household appliance

The invention discloses a gesture recognition method and circuit and a household appliance. The gesture recognition method comprises the steps that a plurality of continuous first preset periods are configured to control four infrared transmitting tubes, in each first preset period, the four infrared transmitting tubes are sequentially controlled to be in a running state, and the infrared transmitting tubes in the running state are intermittently lightened. And based on the preset speed and the distance between the two infrared transmitting tubes in the same direction, determining the operation duration of each infrared transmitting tube in the operation state. And when each infrared transmitting tube is in a running state, configuring corresponding transmitting data in the corresponding running duration. Different infrared transmitting tubes are configured with different transmitting data, and the transmitting data comprise a first data code and a second data code. And determining the infrared transmitting t
