[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0034] See also Figures 1 to 8 The utility model provides a range hood, comprising a range hood body 1, a light emitting component 2 and a detection module 3.

[0035] The range hood body 1 has a back plate 11 , and a light-emitting display area 111 is provided on the back plate 11 . The light-emitting display area 111 is provided on the back plate 11 so that the light emitted by the light-emitting component 2 can be illuminated through the light-emitting display area 111 .

[0036] The light-emitting component 2 is arranged in the range hood body 1 and is located at the rear side of the back plate 11. The light-emitting area of ​​the light-emitting component 2 is aligned with the light-emitting display area 111. The display color of the light-emitting component 2 is changeable, and the light emitted by the light-emitting component 2 is emitted from the light-emitting display area 111. The light-emitting area of ​​the light-emitting component 2 is aligned with the light-emitting display area 111, so that the light emitted by the light-emitting component 2 can be better emitted from the light-emitting display area 111. At the same time, by displaying the light-emitting component 2 with changeable color, the brightness at the back plate 11 of the range hood is enhanced, and it is also convenient to display the color according to the actual operating status of the range hood, so that the user can perceive the operating status of the range hood in time.

[0037] The detection module 3 is arranged in the range hood body 1, and the detection end of the detection module 3 extends out of the range hood body 1. The detection module 3 is connected to the main control board of the range hood body 1, and is connected to the designated electrical appliance through a wireless module. The detection module 3 is used to detect the parameters of the range hood operating environment. The light-emitting component 2 determines the color display based on the detection result of the detection module 3, and the designated electrical appliance determines the operating state based on the detection result of the detection module 3. In this embodiment, the detection module 3 selects an existing detection module 3, such as a humidity sensor or a temperature sensor; the designated electrical appliance is an existing electrical appliance, such as a humidifier dehumidifier or an air conditioner. Based on the detection of the operating status of the range hood by the detection module 3, the light-emitting component 2 can display different colors through an existing analog circuit. While displaying the color, the light-emitting component 2 transmits a signal through an existing wireless module according to the detection result of the detection module 3, so as to realize that the designated electrical appliance enters a determined operating state. Therefore, when the light-emitting component 2 emits light of different colors, the designated electrical appliance can enter different operating states, thereby improving the user's perception. In order to better and more quickly control the display color of the light-emitting component 2 and the operating status of the designated electrical appliance, the main control board of the range hood body 1 controls the display color of the light-emitting component 2 according to the detection result of the detection module 3, and controls the operating status of the designated electrical appliance through the wireless module. Thus, the light-emitting component 2 and the designated electrical appliance can be controlled more conveniently.

[0038] When the user uses the utility model, the range hood body 1 absorbs the oil smoke and discharges it to the outside. At the same time, the light emitted by the light-emitting component 2 is emitted from the light-emitting display area 111 of the back panel 11, which not only enhances the brightness at the back panel 11 of the range hood, and facilitates the user to cook better when the oil smoke is too heavy, but also detects the detection results of the parameters of the range hood operating environment through the detection module 3. The light of different colors emitted by the light-emitting component 2 changes color according to the operating status of the designated electrical appliance linked to the range hood, so that the light of different colors emitted by the light-emitting component 2 makes the light-emitting display area 111 illuminate in different colors, so that the user can intuitively perceive the operating environment of the range hood. At the same time, the color displayed in the light-emitting display area 111 also facilitates the user to intuitively understand the operating status of the designated electrical appliance.

In this embodiment, the display color of the light-emitting component 2 is controlled by an existing analog circuit. In order to more efficiently control the display color of the light-emitting component 2 and the designated electrical appliance linked to the range hood, the detection module 3 sets the thresholds C1 and C2 respectively. When the measured value C of the detection module 3 satisfies: C≤C1, the main control board of the range hood body 1 makes the display color of the light-emitting component 2 D1, and makes the designated electrical appliance enter the first operating state through the wireless module; when the measured value C of the detection module 3 satisfies: C1<C≤C2, the main control board of the range hood body 1 makes the display color of the light-emitting component 2 D2, and makes the designated electrical appliance enter the second operating state through the wireless module; when the measured value C of the detection module 3 satisfies: C>C2, the main control board of the range hood body 1 makes the display color of the light-emitting component 2 D3, and makes the designated electrical appliance enter the third operating state again through the wireless module. In this embodiment, the light-emitting component 2 emits different colors of light according to the detection result of the detection module 3, so that the user can timely perceive the operating state of the designated electrical appliance linked to the range hood according to the display color of the light-emitting display area 111.
