Embodiment 1

[0031] The embodiment of the present invention provides an infrared control method for a range hood, see figure 1 As shown in the flowchart of the infrared control method of the range hood, the method includes the following steps:

[0032] Step S102, during the operation of the range hood, the infrared wavelength signal of the preset detection area is received in real time.

[0033] The controller or main control board of the range hood receives the infrared wavelength signal collected by the infrared control module, and the infrared control module continuously collects the preset detection area in real time during the operation of the range hood. Wherein, the preset detection area is the heating area of ​​the cooker, or the area of ​​cooking utensils such as a pot placed on the cooker.

[0034] In this embodiment, the above-mentioned infrared control module adopts a passive infrared sensor module, and the controller or main control board receives the infrared wavelength signal of th...

Embodiment 2

[0065] The embodiment of the present invention provides an infrared control method for a range hood, taking the conversion of an infrared wavelength signal into a temperature feedback signal as an example for description.

[0066] See image 3 The illustrated schematic diagram of the control principle of the range hood shows an electric control board 31 and an infrared module 32, and the infrared module 32 receives the infrared waves radiated by the pan 33. Among them, the infrared module 32 collects the infrared wavelength in the pot 33, and the infrared module converts the wavelength signal into a temperature signal and feeds it back to the electric control board 31 of the range hood. The electric control board performs intelligent control according to the feedback temperature range, temperature change trend and temperature difference. The air volume of the range hood.

[0067] The infrared sensor module collects the infrared wavelength in the pot and converts it into a temperatu...

Embodiment 3

[0080] The embodiment of the present invention provides an infrared control device for a range hood, Figure 4 Shows a structural block diagram of an infrared control device for a range hood provided by an embodiment of the present invention, and the device includes:

[0081] The receiving module 41 is used to receive the infrared wavelength signal of the preset detection area in real time during the operation of the range hood;

[0082] The conversion module 42 is used to convert the infrared wavelength signal into a feedback signal when the infrared wavelength signal is received;

[0083] The determining module 43 is used to determine the strength, change trend and signal difference of the feedback signal;

[0084] The control module 44 is used to control the air volume of the range hood according to the strength, change trend and signal difference.

Abstract

The invention provides a range hood infrared control method, a device, a range hood controller and a range hood and relates to the technical field of range hoods. The range hood infrared control method comprises the following steps: in the operation process of the range hood, receiving infrared wavelength signals of preset detection areas in real time; when the infrared wavelength signals are received, converting the infrared wavelength signals into feedback signals; confirming the intensity, the variation trend and the signal differences of feedback signals; controlling the intensity of the range hood according to the intensity, the variation trend and the signal differences of the feedback signals. By adopting the range hood infrared control method, the device, the range hood controllerand the range hood provided by the embodiment of the invention, the infrared wavelength signals of the preset detection areas can be received in real time and converted into feedback signals in the operation process of the range hood, the intensity, the variation trend and the signal differences of the feedback signals are confirmed, furthermore the air sucking capacity of the range hood can be controlled according to the intensity, the variation trend and the signal differences of the feedback signals, the cooking state can be precisely reflected, and furthermore the air sucking capacity of the range hood is precisely controlled.

Description

Technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood infrared control method, device, range hood controller and range hood. Background technique [0002] When cooking in the kitchen, the user needs to repeatedly adjust the air volume of the range hood according to the amount of oil smoke generated and the firepower of the stove. The initial adjustment method is controlled by the buttons on the range hood, but the user's fingers are stained with water or oil, which will cause the buttons to stick to oil when touching the buttons, and the dirty buttons will make the buttons dirty; at the same time, the dirty buttons will also pollute. Hands, which cause hygiene problems when they touch food. [0003] The prior art generally uses voice recognition, gesture recognition, or infrared recognition to free the hands to realize the control of the range hood. However, the noise during the operation of the range hood often leads to...
