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...

Abstract

The invention discloses a range hood non-contact control method based on infrared rays. The control method comprises the steps that the infrared receiving and transmitting module transmits infrared rays in real time, receives an action instruction of the gesture control module and transmits the received action instruction to the main control module, and the main control module adjusts the currentworking state of the extractor hood according to the preset corresponding relation between the action instruction and the working state of the extractor hood. Due to the fact that the infrared ray data currently transmitted by the infrared ray receiving and transmitting module are different from the infrared ray data transmitted at the previous moment, infrared rays with the same frequency in theenvironment can be distinguished, and the problems that under the condition of same-frequency infrared ray interference, an infrared gesture control function fails and a gesture function is triggeredby mistake are solved.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and in particular relates to an infrared-based non-contact control method and control system for range hoods. Background technique [0002] The range hood has changed the general environment of the kitchen. It can quickly take away the oily fume harmful to the kitchen environment and human body, discharge the oily fume to the outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. After a range hood is used for a long time, the touch panel or the push switch will be stained with oil. At this time, the fingers will be dirty when operating it. In addition, when there are kitchen utensils in the hand or the hands are dirty, the touch panel will be polluted. panel or push switch. [0003] Therefore, a gesture control system is proposed to realize the operation of the range hood; however, most of the existing range hoods have the gestur...
