Embodiment 1
[0073] This embodiment provides a detection device 100 for the liquid level of the oil cup of the range hood, such as figure 1 As shown, the detection device includes a light emitting module 110 and a photoelectric module 120 .
[0074] Both the light emitting module 110 and the photoelectric module 120 are located above the liquid surface of the oil cup and are on the same horizontal plane.
[0075] The light emitting module 110 and the photoelectric module 120 are connected in communication.
[0076] The light emitting module 110 is used for emitting N light beams to the liquid surface of the oil cup, where N≥1 and N is an integer.
[0077] Wherein, different light beams correspond to different first incident angles.
[0078] The photoelectric module 120 is used to obtain the first incident angle in the light-emitting module 110 when receiving the light beam at the first incident angle reflected by the liquid surface of the oil cup, and obtain the distance from the photoel...
Embodiment 2
[0132] This embodiment provides a method for detecting the liquid level of the oil cup of the range hood, such as image 3 As shown, the detection method is realized by the detection device of the oil cup liquid level of the range hood in the above-mentioned embodiment 1, and the detection method includes:
[0133] S101. The light emitting module emits N light beams to the liquid surface of the oil cup, where N≥1 and N is an integer.
[0134] Wherein, different light beams correspond to different first incident angles.
[0135] S102. When the photoelectric module receives the reflected light reflected from the liquid surface of the oil cup by the light beam of the first incident angle, obtain the first incident angle in the light emitting module, and obtain the first incident angle from the photoelectric module to the liquid surface of the oil cup according to the first incident angle. A height value.
[0136] Specifically, step S102 includes:
[0137] S1021. When N=1, the ...

Abstract
The invention discloses a device and a method for detecting an oil cup liquid level of a kitchen ventilator. The detection device comprises a light-emitting module and a photovoltaic module, wherein the photovoltaic module is used for acquiring a first incident angle in the light-emitting module and acquiring a first height value between the photovoltaic module and the oil cup liquid level according to the first incident angle when receiving a reflected light reflected by a light beam passing through the oil cup liquid level; the photovoltaic module is further used for acquiring a target incident angle in the light-emitting module and acquiring a target height value between the photovoltaic module and an oil cup bottom according to the target incident angle when receiving a reflected lightreflected by a light beam with the target incident angle on the oil cup liquid level; and the photovoltaic module is further used for calculating a difference value between the target height value and the first height value so as to obtain a target oil cup liquid level. According to the device and the method for detecting the oil cup liquid level of the kitchen ventilator provided by the invention, the oil cup liquid level is automatically detected, a user is timely reminded of cleaning when the liquid level height reaches to the setting conditions, and the occurrence of the phenomenon that liquid is fully filled so as to overflow to pollute the kitchen environment is avoided.
Description
technical field [0001] The invention relates to the technical field of smart kitchens, in particular to a device and method for detecting the liquid level of an oil cup of a range hood. Background technique [0002] At present, with the improvement of living conditions, the range hood has become an essential kitchen appliance in every household. The range hood is equipped with an oil cup to store oil. When the oil in the oil cup has accumulated to a certain level, it needs to be removed in time Pour away any oil in the oil cup to prevent spillage. [0003] Most of the oil cups of traditional range hoods are made of transparent plastic so that users can observe the liquid level in the oil cup. But after using for a long time, due to the bad kitchen environment, oil stains will adhere to the surface of the oil cup, thereby causing the user to be unable to observe the liquid level in the oil cup clearly. Contents of the invention [0004] The technical problem to be solved ...
