Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] Embodiment 1 of the present invention provides an infrared-based non-contact control method for range hoods, such as figure 1 As shown, it specifically includes the following steps:
[0033] Step 1, the infrared transceiver module 2 sends infrared signals in real time;
[0034] Specifically: the infrared data currently emitted by the infrared transceiver module 2 is different from the infrared data emitted at the previous moment, and is used to distinguish infrared rays of the same frequency in the environment;
[0035] For example: if figure 2 As shown, in order to distinguish it from t...
