Description

[0001] The utility model relates to the technical field of household appliances, in particular to an oil fume treatment device. Background Art

The transparent panel includes a front surface and a rear surface arranged in the front-back direction. The transparent panel further includes a light-incident surface and a light-emitting surface. The light-incident surface and the light-emitting surface are arranged between the front surface and the rear surface. The light-emitting surface forms side edges with the front surface and the rear surface respectively.

[0003] The light-emitting member is arranged on one side of the light-incident surface. The existing light-emitting surface is a smooth plane. Since the distance between the front surface and the rear surface is relatively small and parallel, if the incident angle of the light inside the transparent panel exceeds a certain value, total reflection will occur until the light is reflected to the side edge and then the light can be refracted out. Therefore, the side edge of the transparent panel will be seen to be a little brighter, and the overall light-emitting effect of the light-emitting surface is poor, and a good ambient light effect of the operation panel assembly cannot be achieved.

[0004] Therefore, there is an urgent need to design a new oil fume treatment device to improve the above problems. Summary of the Utility Model

[0067] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and implementation manners. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only parts related to the present utility model are shown in the accompanying drawings, rather than all of them.

[0068] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0069] In the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0070] In the description of the embodiments of the present disclosure, the orientation or positional relationships such as "above", "below", "left" and "right" are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0071] As Figure 1 、 Figure 2 、 Figure 26 and Figure 30 shown, this embodiment provides an oil fume treatment device, which can be an oil fume extractor, an integrated stove, etc. This embodiment of the present disclosure takes an oil fume extractor as an example for illustration. The oil fume extractor includes a housing 200, a fan 700 and a movable part 300. Among them, the fan 700 is arranged inside the housing 200. The movable part 300 includes a smoke collecting cavity body 310 and a smoke baffle 320. The smoke collecting cavity body 310 can extend out of or retract into the housing 200. An air inlet 3101 is formed on the smoke collecting cavity body 310. The smoke baffle 320 is arranged on the smoke collecting cavity body 310, and the smoke baffle 320 can switch between a first state of opening the air inlet 3101 and a second state of blocking the air inlet 3101. As Figure 30 shown, when the smoke collecting cavity body 310 extends out of the housing 200 and the smoke baffle 320 is in the first state, the oil fume passes through the air inlet 3101, the inside of the smoke collecting cavity body 310 and the housing 200 in sequence and then is discharged. When the smoke collecting cavity body 310 retracts into the housing 200 and the smoke baffle 320 is in the second state, a better retracting effect of the movable part 300 can be achieved. It should be noted that the aforementioned oil fume extractor is only one type of telescopic oil fume extractor, and the oil fume extractor in this embodiment of the present disclosure can also be various types of oil fume extractors such as top suction type, side suction type, ultra-thin type, etc. All types of oil fume extractors are within the protection scope of this embodiment of the present disclosure.

[0072] As Figure 1 and Figure 3As shown, the range hood further includes an operation panel assembly 100. The operation panel assembly 100 is disposed on the housing 200. The operation panel assembly 100 is used to display icons 20, and users can operate the icons 20 to implement different functions of the range hood. For example, Figure 1 and Figure 3 As shown, the operation panel assembly 100 includes a transparent panel 10, an optoelectronic component 30, and icons 20. Among them, the transparent panel 10 is directly or indirectly connected to the housing 200. The icons 20 are embedded in the transparent panel 10. The optoelectronic component 30 includes a first light-emitting element 31. The transparent panel 10 includes a light-incident surface 114 and a light-emitting surface 112. The first light-emitting element 31 is disposed on one side of the light-incident surface 114. The first light-emitting element 31 is disposed opposite to the corresponding icon 20. The first light-emitting element 31 can light up the icon 20, so that the icon 20 emits light, which is convenient for users to identify the icon 20, facilitates users to accurately trigger the icon 20, and avoids misoperation of the icon 20 by users. Exemplarily, the transparent panel 10 can be transparent plastic, transparent glass, polymethyl methacrylate, etc. All transparent materials that can be made into a panel are within the protection scope of the embodiments of the present disclosure. Exemplarily, the first light-emitting element 31 can be an RGB lamp, an LED lamp, etc. All structures that can emit light are within the protection scope of the embodiments of the present disclosure. Exemplarily, the icon 20 can be formed by processes such as silk-screening process, etching process, and laser internal engraving process on the inside of the transparent panel 10 through laser, realizing the rapid processing and formation of the icon 20. In an optional embodiment, the icon 20 is located inside the transparent panel 10, and can also prevent the icon 20 from being polluted by external oil fume or oil stains, realizing a better lighting and brightening effect of the icon 20 all the time.

[0073] However, in the existing range hoods, in an environment with strong light, the brightness of the icon 20 is not obvious enough, which affects the display effect of the icon 20 on the operation panel assembly 100, is not conducive to the accurate identification of the icon 20 by users in an environment with strong light, and affects the normal operation of the range hood by users.

[0074] Through the long-term efforts of the R & D personnel, the main reason for the poor lighting effect of the icon 20 is that the thickness of the icon 20 is insufficient. The insufficient thickness of the icon 20 results in poor reflection of light inside the icon 20, resulting in the insufficient brightness of the lit icon 20, which is not conducive to the accurate identification of the icon 20 by users in an environment with strong light, and affects the normal operation of the range hood by users.

[0075] To solve the above problems, in an optional embodiment, as Figure 13 shown, the thickness of the transparent panel 10 is a first thickness D 1 , and the dimension of the icon 20 in the thickness direction of the transparent panel 10 is a second thickness D 2 , where D2 / D 1 Greater than or equal to 1 / 4 and less than 1, the second thickness D of the icon 20 2 Relatively large, which can ensure a good light reflection effect inside the icon 20, ensure that the icon 20 reaches sufficient brightness, so that users can accurately identify the icon 20 even in an environment with strong light, and ensure the normal operation of the user for the operation panel component 100 and the range hood. Exemplarily, D 2 / D 1 Can be 1 / 4, 1 / 3, 1 / 2, etc. The above values are only limited examples, and all values within the range greater than or equal to 1 / 4 and less than 1 are within the protection scope of this optional embodiment.

[0076] In an optional embodiment, as Figure 13 shown, the second thickness D 2 Greater than or equal to 2 mm and less than or equal to 5 mm, the second thickness D of the icon 20 2 Relatively large, which can ensure a good light reflection effect inside the icon 20, ensure that the icon 20 reaches sufficient brightness, so that users can accurately identify the icon 20 even in an environment with strong light, and ensure the normal operation of the user for the operation panel component 100 and the range hood. Exemplarily, it can be 2 mm, 3 mm, 4 mm, 5 mm, etc. All values within the range greater than or equal to 2 mm and less than or equal to 5 mm are within the protection scope of this optional embodiment.

[0077] In an optional embodiment, as Figure 13 shown, the first thickness D 1 Greater than 2 mm and less than or equal to 20 mm, the relatively large first thickness D 1 Can achieve a good support effect on the relatively thick icon 20, and avoid the problem of damage to the transparent panel 10 during use.

[0078] In the prior art, the transparent panel 10 includes a front surface 113 and a rear surface 115 arranged in the front-rear direction. The projection of the icon 20 on the front surface 113 is composed of lines, and the carved lines have a huge impact on the reflection and refraction angles of light. In some cases, thin lines may cause the light reflection amount and refraction amount to be too low, resulting in a weakened light-emitting effect of the icon 20.

[0079] To solve the above problems, in an optional embodiment, as Figure 28As shown, the transparent panel 10 has a front surface 113. The projection of the icon 20 on the front surface 113 is formed by lines, and the width of the lines is greater than or equal to 0.8 mm and less than or equal to 1.2 mm. These relatively wide lines can provide more scratches and surfaces, making it easier for light to be reflected and refracted at the icon 20, ensuring that the icon 20 reaches sufficient brightness so that users can accurately identify the icon 20 even in an environment with strong light, and ensuring the normal operation of the user for the operation panel assembly and the range hood. Exemplarily, the width of the lines can be 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 1 mm, 1.1 mm, 1.2 mm, etc. The above values are only limited examples, and all values within the range of greater than or equal to 0.8 mm and less than or equal to 1.2 mm are within the protection scope of this optional embodiment.

[0080] Engraved glass usually uses high-quality, transparent and impurity-free glass. If poor-quality materials are selected, the reflectivity and refractive index of light on its surface and inside will decrease, which will also have a negative impact on the luminous effect of the icon 20.

[0081] To solve the above problems, in an optional embodiment, the transparent panel 10 is made of ultra-white glass, and the light transmittance of the ultra-white glass reaches 90%. The ultra-white glass has higher quality, higher transparency, fewer impurities and fewer defects, which can effectively improve the reflectivity and refractive index of light at the icon 20, ensuring that the icon 20 reaches sufficient brightness so that users can accurately identify the icon 20 even in an environment with strong light, and ensuring the normal operation of the user for the operation panel assembly and the range hood.

[0082] In an optional embodiment, the light emitted by the first light-emitting member 34 is visible light, which is convenient for users to clearly and obviously identify the luminous icon 20. Specifically, visible light refers to the wavelength within the range of greater than or equal to 390 nm and less than or equal to 760 nm.

[0083] Exemplarily, the wavelength of the light emitted by the first light-emitting member 34 is greater than or equal to 622 nm and less than or equal to 760 nm. The light emitted by the first light-emitting member 34 is red light, and the red light has high recognition, which is convenient for users to identify the luminous icon at a long distance. Exemplarily, the wavelength of the light emitted by the first light-emitting member 34 can be 622 nm, 622 nm, 640 nm, 660 nm, 670 nm, 690 nm, 700 nm, 720 nm, 750 nm, 760 nm, etc. All first light-emitting members 34 whose emitted light wavelength is within the range of greater than or equal to 622 nm and less than or equal to 760 nm are within the protection scope of this optional embodiment, and this optional embodiment will not be listed one by one.

[0084] As an alternative solution, a first light-emitting component 31 that can emit light with a wavelength greater than or equal to 624 nm can be selected. Compared with the wavelength of ordinary red light, which is about 622 nm, the wavelength of super red light can reach 624 nm or above. Under the same environment, super red light has a stronger ability to bypass dust obstruction, so it can be recognized at a farther distance. At the same time, the brighter red color has a better expansion color and warning effect. More importantly, the wavelength of super red light basically leaves the perception range of rod cells and remains within the perception range of cone cells.

[0085] In an alternative embodiment, the color of the light emitted by the first light-emitting component 34 can be red (622 nm ≤ wavelength ≤ 760 nm), orange (597 nm ≤ wavelength < 622 nm), yellow (577 nm ≤ wavelength < 597 nm), green (wavelength is about 555 nm), blue (480 nm ≤ wavelength < 492 nm), purple (350 nm ≤ wavelength < 455 nm), white or other colors. The color of the light emitted by the first light-emitting component 34 can be adjusted according to the specific environment and the user's habits to ensure a better user experience of the range hood. Among them, the human eye with normal vision is most sensitive to green light, so green light can be selected as the light-emitting color of the icon 20.

[0086] In an alternative embodiment, the color of the light emitted by the first light-emitting component 34 is variable. Specifically, the first light-emitting component 34 can be adjusted according to different operation modes of the user for the icon 20, improving the interactivity between the user and the operation of the icon 20 and enhancing the use effect of the range hood by the user.

[0087] In the prior art, as Figure 3 shown, in order to realize the control of different functions of the range hood, at least two icons 20 are provided. The at least two icons 20 are arranged at intervals in the left-right direction. Each icon 20 is correspondingly arranged with a first light-emitting component 34 one by one. The first light-emitting component 34 and the icon 20 are arranged in the up-down direction. Each first light-emitting component 34 can make the correspondingly arranged icon 20 emit light. However, when two adjacent first light-emitting components 34 both emit light, a light bar 800 will be displayed in the area between the two adjacent first light-emitting components 34 on the transparent panel 10. The light bar 800 affects the floating feeling when the icon 20 on the transparent panel 10 emits light and affects the display effect of the operation panel assembly 100.

[0088] After long-term exploration and research by researchers, it is found that the formation of the light bar 800 is mainly due to the interference and superposition of the light emitted by two adjacent first light-emitting components 31. To solve the above problems, as Figure 4 and Figure 5As shown, the operation panel assembly 100 further includes at least two light-shielding members 40. Each light-shielding member 40 corresponds to a first light-emitting member 31 one by one. Each light-shielding member 40 covers the outer periphery of the corresponding first light-emitting member 31. By providing the light-shielding members 40, the mutual interference of the light emitted by two adjacent first light-emitting members 31 can be effectively reduced, avoiding the light bar 800 formed by the mutual interference and superposition of the light emitted by two adjacent first light-emitting members 31, realizing a better floating feeling of the icon 20 on the operation panel assembly 100, and ensuring a better display effect of the operation panel assembly 100. In addition, by providing the light-shielding members 40, the loss of the light emitted by the first light-emitting member 31 can also be effectively reduced, so as to ensure that most of the light emitted by the first light-emitting member 31 can be transmitted to the icon 20, making the icon 20 brighter and making the icon 20 more obvious in a strong light environment.

[0089] In an optional embodiment, as Figure 4 shown, the first light-emitting member 34 and the light-shielding member 40 are disposed on one side of the light-incident surface 114 of the transparent panel 10. The light-incident surface 114 is set as a smooth plane to reduce the reflection of the light emitted by the first light-emitting member 34 on the light-incident surface 114 and reduce the loss of the light emitted by the first light-emitting member 34 during the transmission to the icon 20. The light emitted by the first light-emitting member 34 can enter the transparent panel 10 from the light-incident surface 114 with the least loss, and can also further improve the brightness of the icon 20, making the icon 20 more obvious in a strong light environment.

[0090] In an optional embodiment, as Figure 4 shown, a first light path channel 41 is provided inside the light-shielding member 40. The cross-sectional area of the first light path channel 41 gradually decreases from top to bottom. By providing the first light path channel 41, the converging effect on the light emitted by the first light-emitting member 34 can be realized, so as to make the light transmitted to the icon 20 more converged and concentrated, and make the icon 20 brighter.

[0091] In an optional embodiment, as Figure 5 shown, the light-shielding member 40 includes a light-shielding member body 42 and a first reflective coating 43. The first light path channel 41 is provided on the light-shielding member body 42. The first reflective coating 43 is provided on the inner side surface of the first light path channel 41. The light emitted by the first light-emitting member 31 can be reflected at the first reflective coating 43. The light emitted by the first light-emitting member 31 is reflected and superposed under the action of the first reflective coating 43, realizing a better converging and strengthening effect on the light emitted by the first light-emitting member 31, effectively improving the brightness at the icon 20, and making the icon 20 more obvious in a strong light environment. Exemplarily, the first reflective coating 43 can select a material with good polishing performance, such as an electroless nickel plating layer, etc.

[0092] In an optional embodiment, as Figure 4As shown, the optoelectronic component 30 further includes a first circuit board 33. The first light-emitting element 34 is disposed on the first circuit board 33 and electrically connected to the first circuit board 33. The first circuit board 33 can achieve better power supply and control functions for the first light-emitting element 34, and the first circuit board 33 can be communicatively connected to the controller of the range hood.

[0093] In an alternative embodiment, as Figures 5 - 7 shown, the light-shielding member body 42 includes a light guide cone 421 and a mounting flange 422. The first light path channel 41 is opened on the light guide cone 421. The mounting flange 422 abuts against and is fixed to the first circuit board 33. Since the contact area between the mounting flange 422 and the first circuit board 33 is large, a firm connection between the light-shielding member body 42 and the first circuit board 33 can be achieved. Exemplarily, the mounting flange 422 and the first circuit board 33 can be fixedly connected by fasteners or by welding. Specifically, the fasteners can be screws, pins, snap components, magnetic structures, etc. All structures and components that can achieve a firm connection between the mounting flange 422 and the first circuit board 33 are within the protection scope of this alternative embodiment.

[0094] In an alternative embodiment, as Figures 4 - 7 shown, the first circuit board 33 includes a first limiting portion, and the light-shielding member 40 includes a second limiting portion 44. The first limiting portion and the second limiting portion 44 cooperate to define the relative position of the light-shielding member 40 relative to the first circuit board 33, enabling rapid positioning of the light-shielding member 40 and the first circuit board 33, and enabling rapid and accurate installation of the light-shielding member 40 and the first circuit board 33, thereby improving the assembly efficiency of the operator for the operation panel assembly 100. Exemplarily, one of the first limiting portion and the second limiting portion 44 is a limiting protrusion, and the other is a limiting hole. The limiting protrusion can be inserted into the limiting hole to achieve rapid positioning of the light-shielding member 40 and the first circuit board 33.

[0095] In an alternative embodiment, as Figures 4 - 7 shown, the limiting protrusions correspond one-to-one with the corresponding limiting holes. The limiting protrusions are provided with at least two. The provision of at least two limiting protrusions can prevent the light-shielding member 40 from rotating on the first circuit board 33, ensuring an accurate and good protection effect of the light-shielding member 40 on the corresponding first light-emitting element 34.

[0096] In an alternative embodiment, it can also be that the cross-section of the limiting protrusion is set to be non-circular (not shown in the figure). The cooperation between the limiting protrusion and its corresponding limiting hole can also achieve a good effect of preventing the light-shielding member 40 from rotating.

[0097] In an alternative embodiment, as Figure 5As shown, the light-shielding member 40 further includes a sealing member 45. The sealing member 45 is clamped between the mounting flange 422 and the first circuit board 33. The sealing member 45 surrounds the outer periphery of the first light-emitting member 34. The setting of the sealing member 45 can prevent the light emitted by the first light-emitting member 34 from escaping through the gap between the mounting flange 422 and the first circuit board 33, ensuring that more light can smoothly reach the icon 20, ensuring a higher brightness of the icon 20, and making the icon 20 more obvious in a strong light environment. Exemplarily, the sealing member 45 can be rubber, silica gel, etc. with elastic deformation function. The formation of elastic deformation can achieve a better sealing effect on the gap between the mounting flange 422 and the first circuit board 33. Specifically, rubber, silica gel and other products with a darker color can be selected to achieve a better protection effect on light diffusion.

[0098] In an alternative embodiment, as Figure 5 shown, a limiting groove 423 is formed on the light-shielding member 40. The first light-emitting member 34 can be received in the limiting groove 423. The setting of the limiting groove 423 can achieve the quick positioning and pre-assembly effect of the light-shielding member 40 and the first light-emitting member 34, and can effectively improve the quick and accurate assembly effect of the first circuit board 33, the light-shielding member 40 and the first light-emitting member 34.

[0099] In an alternative embodiment, as Figure 4 and Figure 8 shown, the operation panel assembly 100 further includes a convex lens 50. The convex lens 50 is disposed between the first light-emitting member 34 and the icon 20. The convex lens 50 focuses and couples the light emitted by the first light-emitting member 34. The focused and coupled light can further increase the brightness of the icon 20, making the icon 20 more obvious in a strong light environment.

[0100] In an alternative embodiment, as Figure 4 and Figure 8 shown, the convex lens 50 can be selected as a plano-convex lens. The plano-convex lens includes a lens plane and a lens convex surface. The lens plane abuts against the light-emitting plane of the first light-emitting member 34. The lens convex surface is disposed on the side of the convex lens 50 away from the first light-emitting member 34. The lens convex surface is curved towards the first light-emitting member 34. The lens plane and the light-emitting plane of the first light-emitting member 34 are bonded by a transparent optical adhesive, which can achieve a firm connection between the convex lens 50 and the first light-emitting member 34.

[0101] In an alternative embodiment, the convex lens 50 can also be arranged at an interval from the first light-emitting element 34. By providing a bracket for mounting the convex lens 50 inside the first optical path channel 41, the stable setting of the convex lens 50 in the first optical path channel 41 can also be achieved. It should be noted that the convex lens 50 can be not only a plano-convex lens, but also a biconvex lens, etc. All convex lenses 50 that can converge the light emitted by the first light-emitting element 34 are within the protection scope of this alternative embodiment.

[0102] In an alternative embodiment, as Figure 4 shown, the transparent panel 10 includes a transparent panel body 11. A second optical path channel 111 extending in the up-down direction is formed on the transparent panel body 11. One end of the second optical path channel 111 is disposed opposite to the first light-emitting element 34, and the other end of the second optical path channel 111 is disposed opposite to the icon 20. If the light focused and coupled by the convex lens 50 just matches the input end of the second optical path channel 111, that is, the light focused and coupled by the convex lens 50 completely enters the input end of the second optical path channel 111, the light capture rate can reach 80%, further increasing the brightness of the icon 20. It should be noted that the light focused and coupled by the convex lens 50 can be made to completely enter the input end of the second optical path channel 111 by adjusting parameters of the convex lens 50, the distances between the convex lens 50 and the first light-emitting element 34 and the input end of the second optical path channel 111 respectively, the size of the input end of the second optical path channel 111, etc.

[0103] In an alternative embodiment, as Figure 8 shown, a second reflective coating 12 is provided inside the second optical path channel 111. The light entering the second optical path channel 111 through the convex lens 50 can be reflected at the second reflective coating 12. The light is reflected and superimposed under the action of the second reflective coating 12, achieving a better effect of converging and strengthening the light emitted by the light-shielding member 40, and effectively improving the brightness at the icon 20. By providing the second reflective coating 12 in the second optical path channel 111, the structure of the transparent panel 10 is simple, easy to manufacture, and the overall weight is light. Exemplarily, the second reflective coating 12 can be made of a material with good polishing performance, such as an electroless nickel plating layer.

[0104] In an alternative embodiment, as Figure 8 shown, the first refractive index n 1 of the second reflective coating 12 is greater than the second refractive index n 2 of the transparent panel body 11. By adjusting parameters of the convex lens 50, the distances between the convex lens 50 and the first light-emitting element 34 and the input end of the second optical path channel 111 respectively, the size of the input end of the second optical path channel 111, etc., the minimum incident angle α of the light passing through the convex lens 50 incident on the second reflective coating 12min greater than or equal to the first critical angle α of the second reflective coating 12 临界1 , the light passing through the convex lens 50 can undergo total internal reflection at the second reflective coating 12, preventing the light passing through the convex lens 50 from escaping outward from the transparent panel body 11, so that the light passing through the convex lens 50 is completely converged in the second optical path channel 111, ensuring a relatively strong brightness of the icon 20.

[0105] In an alternative embodiment, as Figure 9 shown, the transparent panel 10 further includes a light guide 13 disposed in the second optical path channel 111. The light entering the second optical path channel 111 through the convex lens 50 can undergo total internal reflection in the light guide 13, preventing the light passing through the convex lens 50 from escaping outward from the transparent panel body 11, so that the light passing through the convex lens 50 is completely converged in the light guide 13, ensuring a relatively strong brightness of the icon 20. The third refractive index n of the light guide 13 3 is greater than the second refractive index n of the transparent panel body 11 2 . By adjusting parameters of the convex lens 50, the distances between the convex lens 50 and the input ends of the first light-emitting member 34 and the second optical path channel 111 respectively, the size of the input end of the second optical path channel 111, etc., the minimum incident angle α of the light passing through the convex lens 50 incident on the light guide 13 min is greater than or equal to the second critical angle α of the light guide 13 临界2 , the light passing through the convex lens 50 can undergo total internal reflection at the light guide 13, preventing the light passing through the convex lens 50 from escaping outward from the transparent panel body 11, so that the light passing through the convex lens 50 is completely converged in the light guide 13, ensuring a relatively strong brightness of the icon 20.

[0106] In an alternative embodiment, as Figures 10 - 15 shown, the operation panel assembly 100 further includes a mounting assembly 60. The first light-emitting member 34 is disposed at the upper end of the transparent panel body 11. The upper end of the transparent panel body 11 is fixedly connected to the mounting assembly 60. The upper end of the transparent panel body 11 and the first light-emitting member 34 are both disposed inside the mounting assembly 60. The mounting assembly 60 can achieve a good shielding effect on the first light-emitting member 34. When the icon 20 is illuminated by the corresponding first light-emitting member 34, from the user's perspective, only the glowing icon 20 floating on the transparent panel body 11 can be seen. The glowing icon 20 has a good sense of suspension and a sense of technology, improving the user's experience.

[0107] In an alternative embodiment, as Figures 10 - 13As shown, the mounting assembly 60 includes a mounting module. The mounting module includes a first mounting member 61 and a second mounting member 62. The first mounting member 61 and the second mounting member 62 are located on the front and rear sides of the transparent panel body 11. The mounting module is fixedly connected to the first circuit board 33. The first mounting member 61 and the second mounting member 62 jointly clamp the upper end of the transparent panel body 11 in the front-rear direction. Through the cooperation of the first mounting member 61, the second mounting member 62, and the first circuit board 33, with fewer structures, the mounting assembly 60 can firmly clamp the transparent panel body 11, realizing a firm connection between the mounting assembly 60 and the transparent panel body 11.

[0108] In an alternative embodiment, as Figure 12 and Figure 13 shown, the first mounting member 61 includes a first mounting portion 611 and a first adhesive portion 612. One side of the first adhesive portion 612 is adhered to the first mounting portion 611, and the other side of the first adhesive portion 612 is adhered to one side of the transparent panel body 11. The second mounting member 62 includes a second mounting portion 621 and a second adhesive portion 622. One side of the second adhesive portion 622 is adhered to the second mounting portion 621, and the other side of the second adhesive portion 622 is adhered to the other side of the transparent panel body 11. Through the arrangement of the first adhesive portion 612 and the second adhesive portion 622, the firm connection between the first mounting member 61 and the second mounting member 62 and the transparent panel body 11 can be further improved, further enhancing the firm connection between the mounting assembly 60 and the transparent panel body 11. Exemplarily, the first adhesive portion 612 and the second adhesive portion 622 can be double-sided tapes, thereby realizing the firm connection effect between the first mounting member 61 and the second mounting member 62 and the transparent panel body 11 respectively.

[0109] As Figure 12 and Figure 13 shown, the first circuit board 33 is located at the upper end of the mounting assembly 60. The first circuit board 33, the first mounting member 61, the second mounting member 62, and the transparent panel body 11 jointly form an accommodation space 70. The first light-emitting member 34 and the light-shielding member 40 are both arranged in the accommodation space 70. In a limited and narrow space, a reasonable arrangement of the first circuit board 33, the first mounting member 61, the second mounting member 62, the transparent panel body 11, the first light-emitting member 34, and the light-shielding member 40 can be realized, making each part of the operation panel assembly 100 more compactly arranged, reducing the overall volume and thickness of the operation panel assembly 100, and facilitating the operator to quickly assemble the operation panel assembly 100 onto the housing 200.

[0110] In an alternative embodiment, as Figures 10 - 13As shown, the housing 200 has a lower opening. The installation assembly 60 further includes a plugging member 64. The plugging member 64 can plug the lower opening on the housing 200, which can prevent the internal structure of the range hood from being exposed through the lower opening and prevent the oil droplets inside the range hood from leaking through the lower opening, achieving a better sealing effect on the internal structure of the range hood. As Figures 10 - 13 shown, the installation assembly 60 further includes a decorative member 63. The plugging member 64 is disposed between the installation module and the decorative member 63. The installation module is connected to the decorative member 63. The installation module and the decorative member 63 jointly clamp the plugging member 64 in the up-and-down direction, thereby realizing the stable connection of the plugging member 64 with the installation module and the decorative member 63 respectively. Exemplarily, the installation module and the decorative member 63 are fixedly connected by a fixing member 66, thereby realizing the tight fixed connection of the installation module, the decorative member 63 and the plugging member 64 in the up-and-down direction. Specifically, the fixing member 66 can be a screw, a pin, a snap component, etc. All structures that can realize the fixed connection of the installation module and the decorative member 63 are within the protection scope of this optional embodiment.

[0111] In an optional embodiment, as Figure 2 、 Figure 10 and Figure 11 shown, the housing 200 includes a first quick-release member 210, and the operation panel assembly 100 includes a second quick-release member 65. The first quick-release member 210 and the second quick-release member 65 are detachable, thereby realizing the quick disassembly and replacement of the operation panel assembly 100 and the housing 200, which is convenient for the user to quickly repair or replace the operation panel assembly 100. Exemplarily, the first quick-release member 210 and the second quick-release member 65 can be a snap structure, a magnetic attraction structure, etc. All structures that can realize quick disassembly and assembly are within the protection scope of this optional embodiment.

[0112] In an optional embodiment, as Figure 14 shown, the first installation portion 611 includes a first fixing bracket 6111 and a first connecting member 6112 that are connected in sequence. Among them, the first fixing bracket 6111 is fixedly connected to the plugging member 64, and the first connecting member 6112 is used to achieve a relatively stable supporting effect on the first circuit board 33. In an optional embodiment, as Figure 14 shown, the second installation portion 621 includes a second fixing bracket 6211 and a second connecting member 6212 that are connected in sequence. Among them, the second fixing bracket 6211 is fixedly connected to the plugging member 64, and the second connecting member 6212 is used to achieve a relatively stable supporting effect on the first circuit board 33.

[0113] In an optional embodiment, as Figure 14As shown, the first fixing bracket 6111 includes a first support portion 61111, a first connecting portion 61112, and a second support portion 61113 that are connected in sequence. Among them, the first support portion 61111 is in surface-to-surface contact with the plugging member 64, so as to achieve a stable support effect of the plugging member 64 on the first support portion 61111.

[0114] In an alternative embodiment, as Figure 14 shown, the first connecting member 6112 includes a first side attaching portion 61123, a third support portion 61121, and a first limiting member 61122 that are connected in sequence. The first side attaching portion 61123 is arranged parallel to the transparent panel 10, so as to achieve a firm pasting effect of the first pasting portion 612 on the first side attaching portion 61123 and the transparent panel 10, and avoid the separation of the first side attaching portion 61123 from the transparent panel 10.

[0115] In an alternative embodiment, as Figure 14 shown, the third support portion 61121 is in surface-to-surface contact with the second support portion 61113, which can achieve a stable support effect of the first fixing bracket 6111 on the first connecting member 6112.

[0116] In an alternative embodiment, as Figure 14 shown, the first circuit board 33 is disposed on one side of the first limiting member 61122. The first limiting member 61122 can achieve a limiting effect on the first circuit board 33, and can effectively improve the installation efficiency and installation accuracy of the first circuit board 33 and the installation component 60.

[0117] In an alternative embodiment, as Figure 14 shown, the second fixing bracket 6211 includes a fourth support portion 62111, a second connecting portion 62112, and a fifth support portion 62113 that are connected in sequence. Among them, the fourth support portion 62111 is in surface-to-surface contact with the plugging member 64, so as to achieve a stable support effect of the plugging member 64 on the fourth support portion 62111.

[0118] In an alternative embodiment, as Figure 14 shown, the second connecting member 6212 includes a second side attaching portion 62123, a sixth support portion 62121, and a second limiting member 62122 that are connected in sequence. The second side attaching portion 62123 is arranged parallel to the transparent panel 10, so as to achieve a firm pasting effect of the second pasting portion 622 on the second side attaching portion 62123 and the transparent panel 10, and avoid the separation of the second side attaching portion 62123 from the transparent panel 10.

[0119] In an alternative embodiment, as Figure 14As shown, the sixth support portion 62121 and the fifth support portion 62113 are in surface contact with each other, so that the second fixing frame 6211 can achieve a stable supporting effect on the second connecting member 6212 .

[0120] In an optional embodiment, if Figure 14 As shown, the first circuit board 33 is disposed on one side of the second stopper 62122, and the second stopper 62122 can achieve a stopper effect on the first circuit board 33, and can effectively improve the installation efficiency and installation accuracy of the first circuit board 33 and the installation assembly 60. The first stopper 61122 and the second stopper 62122 can form an installation space 67, and the first circuit board 33 is installed in the installation space 67. The first stopper 61122 cooperates with the second stopper 62122 to achieve a better stopper effect on the first circuit board 33.

[0121] In an optional embodiment, if Figure 27 As shown, the second quick release part 65 includes a connected clamping protrusion 651 and a second quick release part body 652, the second quick release part body 652 is arranged on the blocking part 64, the first quick release part 210 includes a first quick release part body 2103 and a first elastic deformation part 2101 and a second elastic deformation part 2102 arranged thereon, the first elastic deformation part 2101 and the second elastic deformation part 2102 are arranged oppositely, the clamping protrusion 651 can be inserted between the first elastic deformation part 2101 and the second elastic deformation part 2102 and clamped by the first elastic deformation part 2101 and the second elastic deformation part 2102, so as to realize the stable connection and quick disassembly of the operation panel assembly 100 and the housing 200. In an optional embodiment, the structures of the first quick release part 210 and the second quick release part 65 can also be interchanged, which can also achieve the above effect.

[0122] In an optional embodiment, if Figure 2 , Figure 10 as well as Figure 11 As shown, the first quick release part 210 and the second quick release part 65 together constitute a quick release assembly. The quick release assembly is provided in multiple groups, and the multiple groups of quick release assemblies are arranged at intervals along the circumference of the transparent panel 10, so as to achieve a stable connection between the housing 200 and the operation panel assembly 100.

[0123] In an optional embodiment, if Figure 13 and Figure 18 As shown, the operation panel assembly 100 also includes a first detection mechanism 32, which is electrically connected to the controller of the range hood. The first detection mechanism 32 is used to detect the user's triggering operation on the corresponding icon 20, and the controller controls the relevant mechanisms of the range hood to work according to the trigger signal sent by the first detection mechanism 32.

[0124] In an optional embodiment, ifFigure 13 and Figure 18 As shown in Figure 18 , the operation panel assembly 100 further includes a first protective cover 80. The first detection mechanism 32 is disposed within the first protective cover 80. The first protective cover 80 isolates the first detection mechanism 32 from the first light-emitting member 34, which can avoid the influence of the light emitted by the first light-emitting member 34 and external light on the signal transmission and reception of the first detection mechanism 32, and ensure the accurate detection of whether the user triggers the corresponding icon 20 by the first detection mechanism 32. Exemplarily, the first detection mechanism 32 can be an infrared detection mechanism, a laser detection mechanism, a thermal imaging detection mechanism, an image forming detection mechanism, etc. All structures capable of detecting whether the user operates are within the protection scope of this optional embodiment.

[0125] As an optional embodiment, as Figure 12 and Figure 13 shown in Figure 13 , the first protective cover 80 and the mounting assembly 60 are integrally formed, which can effectively simplify the structural design of the operation panel assembly 100 and reduce parts and the assembly process.

[0126] In an optional embodiment, as Figure 18 shown in Figure 18 , the first detection mechanism 32 includes at least two groups of probe assemblies 321. Each group of probe assemblies 321 corresponds to a corresponding icon 20 one by one. Among them, the first protective cover 80 includes a first protective cover body 81 and a first partition 82 disposed therein. A first partition 82 is disposed between adjacent two groups of probe assemblies 321. The first partition 82 can completely separate adjacent two groups of probe assemblies 321. Through the setting of the first partition 82, the mutual interference between different groups of probe assemblies 321 can be avoided, and the accurate detection of the user operation on the corresponding icon 20 by each group of probe assemblies 321 can be realized. In addition, since multiple groups of probe assemblies 321 share a first protective cover body 81, the structure of the first protective cover 80 is simple and the overall number of components of the operation panel assembly 100 is relatively small.

[0127] As an optional embodiment, as Figure 14 shown in Figure 14 , the first protective cover body 81 includes a positioning protrusion 811. A positioning hole 641 is formed on the plugging member 64. The positioning protrusion 811 can be inserted into the positioning hole 641 to realize the quick positioning when the first protective cover body 81 and the plugging member 64 are assembled, effectively improving the assembly efficiency of the first protective cover 80 and the plugging member 64 and facilitating the quick assembly of the operation panel assembly 100.

[0128] In an optional embodiment, it can also be that the first protective cover 80 is provided as at least two, and each first protective cover 80 corresponds to an icon 20 one by one, which is convenient for the quick assembly of each first protective cover 80 and the corresponding icon 20.

[0129] In an optional embodiment, asFigure 18 As shown, the probe assembly 321 includes a transmitting probe 3211 and a receiving probe 3212. The first protective cover 80 further includes a second partition 83. A second partition 83 is provided between the transmitting probe 3211 and the receiving probe 3212. The second partition 83 can completely separate the transmitting probe 3211 and the receiving probe 3212, avoiding the mutual interference of the transmitted signal and the received signal, so as to ensure a more accurate detection effect of the probe assembly 321. Specifically, when the user's finger 600 is located below the first detection mechanism 32, the signal emitted by the transmitting probe 3211 is reflected at the finger 600, and the reflected signal is received by the receiving probe 3212, thereby realizing the recognition of the finger 600 triggering the icon 20 by the probe assembly 321.

[0130] In an alternative embodiment, as Figure 9 、 Figure 19 、 Figure 20 and Figure 21 shown, the operation panel assembly 100 further includes a lens assembly 90. The lens assembly 90 includes a plurality of plano-convex cylindrical lenses 91 arranged in the left-right direction. The focal line L a of the plano-convex cylindrical lens 91 extends in the up-down direction. The plano-convex cylindrical lens 91 includes a plane 911 and a convex surface 912. The plane 911 is arranged parallel to the front surface 113 of the transparent panel 10. The convex surface 912 is located on the front side of the plane 911 and bends towards the transparent panel 10. Due to the optical characteristics of the plano-convex cylindrical lens 91, when observed from the user's perspective, the light bar 800 observed by the user on the convex surface 912 is pulled into an extremely thin long strip. From the perspective of naked-eye observation, the user can hardly see the existence of the light bar 800 from the convex surface 912, thereby realizing a better "invisible" effect on the light bar 800, and thus realizing a better invisible effect of the lens assembly 90 on Figure 3 the light bar 800 therein.

[0131] In an alternative embodiment, as Figure 19 shown, the dimension of the plano-convex cylindrical lens 91 in the left-right direction is the first dimension L 1 , and the dimension of the plano-convex cylindrical lens 91 in the up-down direction is the second dimension L 2 , where L 2 / L 1 is greater than or equal to 6. By providing the slender plano-convex cylindrical lens 91, a better "invisible" effect on the light bar 800 can be achieved, and a better floating effect of the illuminated icon 20 can be realized. Exemplarily, L 2 / L 1 can be 6, 7, 8, 9, 10, etc. This alternative embodiment does not completely list all values, and all values greater than or equal to 6 are within the protection scope of this alternative embodiment.

[0132] In an alternative embodiment, the lens assembly 90 is an integral structure. The lens assembly 90 is located between the first light-emitting member 34 and the icon 20 in the up-down direction. The lens assembly 90 can completely cover all the light emitted by the first light-emitting members 34. The structure of the lens assembly 90 is simple, and it is convenient for the quick assembly of the lens assembly 90 and the transparent panel 10. In an alternative embodiment, the plano-convex cylindrical lens 91 can be formed by injection molding, etching, or cutting processes, which improves the processing efficiency of the plano-convex cylindrical lens 91 and facilitates the rapid manufacturing of the plano-convex cylindrical lens 91.

[0133] In an alternative embodiment, as Figure 22 shown, the lens assembly 90 further includes a substrate 92. One side surface of the substrate 92 abuts against the front surface 113 of the transparent panel 10, and the other side surface of the substrate 92 abuts against the plane 911. The substrate 92 and the plurality of plano-convex cylindrical lenses 91 are an integral structure, which is convenient for the quick assembly of the lens assembly 90 and the transparent panel 10. It should be noted that the substrate 92 and the transparent panel 10 can be adhered by an optical adhesive, and the substrate 92 and the plurality of plano-convex cylindrical lenses 91 can be integrally formed or adhered by an optical adhesive.

[0134] In an alternative embodiment, as Figure 23 shown, the lens assembly 90 further includes a first optical adhesive layer 94. The first optical adhesive layer 94 is disposed between the plano-convex cylindrical lens 91 and the substrate 92. The setting of the first optical adhesive layer 94 can not only ensure the good transmission and display of light, but also ensure the stable connection between the plano-convex cylindrical lens 91 and the substrate 92, avoid the separation between the plano-convex cylindrical lens 91 and the substrate 92, ensure the good use effect of the lens assembly 90 all the time, and effectively improve the service life of the lens assembly 90. Exemplarily, the first optical adhesive layer 94 can be made of adhesives such as silicone rubber, acrylic resin, unsaturated polyester, polyurethane, and epoxy resin. All types of optical adhesives are within the protection scope of this alternative embodiment.

[0135] In an alternative embodiment, as Figure 23 shown, the lens assembly 90 further includes a second optical adhesive layer 95. The second optical adhesive layer 95 is disposed between the substrate 92 and the front surface 113. The setting of the second optical adhesive layer 95 can not only ensure the good transmission and display of light, but also ensure the stable connection between the substrate 92 and the transparent panel 10, avoid the separation between the substrate 92 and the transparent panel 10, ensure the good use effect of the lens assembly 90 all the time, and effectively improve the service life of the lens assembly 90. Exemplarily, the second optical adhesive layer 95 can be made of adhesives such as silicone rubber, acrylic resin, unsaturated polyester, polyurethane, and epoxy resin. All types of optical adhesives are within the protection scope of this alternative embodiment.

[0136] In an alternative embodiment, asFigure 24 and Figure 25 As shown in Figure 25 , the lens assembly 90 includes a lens module 93. The lens module 93 is arranged between two adjacent first light-emitting components 34 in the left-right direction. Each lens module 93 only hides the corresponding light bar 800. The overall lens assembly 90 requires less material, which can effectively reduce the cost of the operation panel assembly 100.

[0137] In an optional embodiment, the lens module 93 has a center line L extending in the up-down direction C , and two adjacent first light-emitting components 34 are symmetrically arranged on both sides of the center line L C . The distance between two adjacent first light-emitting components 34 in the left-right direction is a first distance S 1 . The distance between two adjacent lens modules 93 in the left-right direction is a second distance S 2 . Among them, S 2 / S 1 is greater than or equal to 0.4 and less than or equal to 1. This can ensure a good shielding effect of the lens module 93 on the corresponding light bar 800. Exemplarily, S 2 / S 1 can be 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1, etc. This optional embodiment does not completely list all values, and all values greater than or equal to 0.4 and less than or equal to 1 are within the protection scope of this optional embodiment.

[0138] In an optional embodiment, as Figure 15 shown, the optoelectronic component 30 further includes a second light-emitting component 31, and the transparent panel 10 further includes a light-emitting surface 112. The second light-emitting component 31 is arranged on one side of the light-incident surface 114. The light emitted by the second light-emitting component 31 can make the light-emitting surface 112 emit light, and the second light-emitting component 31 can achieve the effect of an ambient light. Specifically, as Figure 15 and Figure 26 shown, the operation panel assembly 100 further includes a second detection mechanism 35. The second detection mechanism 35 and the second light-emitting component 31 are respectively electrically connected to the controller of the range hood. The second detection mechanism 35 is used to detect whether the user is in a preset area. When the second detection mechanism 35 detects that the user is in the preset area, the controller controls the second light-emitting component 31 to emit light, so as to realize the interaction between the second light-emitting component 31 and the user operation. Exemplarily, as Figure 15 shown, the optoelectronic component 30 further includes a second circuit board 36. The second light-emitting component 31 is electrically connected to the second circuit board 36, and the second circuit board 36 is electrically connected to the controller of the range hood.

[0139] As Figures 15 - 17As shown, the light incident surface 114 and the light exit surface 112 are disposed between the front surface 113 and the rear surface 115. The light exit surface 112 forms side edges with the front surface 113 and the rear surface 115 respectively. In the prior art, since the distance between the front surface 113 and the rear surface 115 is relatively small and parallel, if the incident angle of the light inside the transparent panel 10 exceeds a certain value, total internal reflection will occur until the light is reflected to the side edge and then the light can be refracted out. Therefore, the side edge of the transparent panel 10 will be seen to be a bit brighter, and the overall light-emitting effect of the light exit surface 112 is poor, and a better ambient light effect of the operation panel assembly 100 cannot be achieved.

[0140] To solve the above problems, in an optional embodiment, as Figure 15 shown, the light exit surface 112 is a frosted surface. The frosted surface can increase the refraction and reflection of the light emitted by the second light-emitting member 31. The frosted surface forms diffuse reflection, thereby increasing the light-emitting brightness of the light exit surface 112 and effectively enhancing the overall light-emitting effect of the light exit surface 112. The operation panel assembly 100 can achieve a better ambient light effect.

[0141] In an optional embodiment, as Figure 15 shown, the light exit surface 112 includes at least two side surfaces 1121, which can achieve the effect of ambient lights on multiple side surfaces 1121 of the transparent panel 10 and effectively improve the user experience.

[0142] In an optional embodiment, as Figure 16 and Figure 17 shown, the side surface 1121 includes at least two sub-side surfaces 11211 arranged in sequence. The adjacent two sub-side surfaces 11211 are arranged at an angle. The light can be refracted and reflected between at least two sub-side surfaces 11211, further enhancing the overall light-emitting effect of the light exit surface 112 and further improving the ambient light effect of the operation panel assembly 100. Exemplarily, the angle between the adjacent two sub-side surfaces 11211 can be 20°, 30°, 40°, 50°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. The foregoing angles are only for exemplary illustration, and all angles are within the protection scope of this optional embodiment.

[0143] In an optional embodiment, as Figure 16 shown, the sub-side surface 11211 includes a first plane. The structure of the transparent panel body 11 is simple, which is convenient for rapid processing and manufacturing, can effectively improve the production efficiency of the transparent panel 10, and can also effectively improve the production yield of the transparent panel 10.

[0144] In an optional embodiment, as Figure 17As shown, the sub-side surface 11211 includes a connecting arc surface that is bent inwardly toward the transparent panel 10. The provision of the connecting arc surface can further enhance the refraction and reflection intensity of light between the sub-side surfaces 11211, further enhance the overall light-emitting effect of the light-emitting surface 112, and further improve the ambient light effect of the operation panel assembly 100.

[0145] In an alternative embodiment, as Figure 15 shown, the light-emitting surface 112 further includes a transition arc surface 1122. Two adjacent side surfaces 1121 are connected by the transition arc surface 1122. The transition arc surface 1122 is relatively smooth. The provision of the transition arc surface 1122 can avoid damage to the user caused by sharp corners on the transparent panel 10 and ensure the personal safety of the user. In addition, the provision of the transition arc surface 1122 can further enhance the refraction and reflection intensity of light on the light-emitting surface 112, further enhance the overall light-emitting effect of the light-emitting surface 112, and further improve the ambient light effect of the operation panel assembly 100.

[0146] In an alternative embodiment, as Figure 15 shown, the second light-emitting member 31 and the light-incident surface 114 are arranged at intervals along the direction in which the second light-emitting member 31 emits light. The second light-emitting member 31 can increase the irradiation range, reduce the dark area, achieve the lighting uniformity of the light-emitting surface 112 at various positions, and at the same time, can visually hide the second light-emitting member 31.

[0147] In an alternative embodiment, as Figure 15 shown, the operation panel assembly 100 further includes a light-shielding cover 38. A light channel 381 is formed on the light-shielding cover 38. The second light-emitting member 34 is disposed in the corresponding light channel 381. The provision of the light-shielding cover 38 can reduce the problem of light crosstalk between the light emitted by the second light-emitting member 34 and the light emitted by the first light-emitting member 31, ensure the normal lighting of the icon 20, and also ensure a good ambient light effect of the light-emitting surface 112 at all times.

[0148] In an alternative embodiment, as Figure 15 shown, the cross-sectional area of the light channel 381 gradually increases along the direction in which the second light-emitting member 31 emits light, which can increase the irradiation range of the light emitted by the second light-emitting member 31, reduce the dark area, and achieve the lighting uniformity of the light-emitting surface 112 at various positions.

[0149] In an alternative embodiment, as Figure 15 shown, the operation panel assembly 100 further includes a concave lens 37. The concave lens 37 is disposed between the second light-emitting member 31 and the light-incident surface 114, which can increase the irradiation range of the light emitted by the second light-emitting member 31, reduce the dark area, and achieve the lighting uniformity of the light-emitting surface 112 at various positions.

[0150] In an alternative embodiment, the color of the light emitted by the second light-emitting member 31 is different from that of the first light-emitting member 34, which avoids the problem of light leakage between the light emitted by the second light-emitting member 31 and the light emitted by the first light-emitting member 34, ensures the normal lighting of the icon 20, and can also ensure a good atmosphere light effect on the light-emitting surface 112 all the time.

[0151] Exemplarily, the first light-emitting member 34 can be a blue light source, and the second light-emitting member 31 can be a white light source, which can achieve a good distinction between the color of the icon 20 and the color of the atmosphere light, and ensure that the color of the icon 20 is more obvious. It should be noted that the second light-emitting member 31 and the first light-emitting member 34 can also be selected in other different combinations of colors, and the foregoing effects can also be achieved.

[0152] In an alternative embodiment, as Figure 10 and Figure 15 shown, the first light-emitting member 34 and the second light-emitting member 31 are located on the same side of the transparent panel 10, and the second light-emitting member 31 is disposed inside or on the back side of the mounting assembly 60, and the mounting assembly 60 can achieve a good shielding effect on the second light-emitting member 31.

[0153] In an alternative embodiment, as Figure 26 shown, the range hood further includes a second protective cover 400. The second protective cover 400 is disposed in the housing 200 and cooperates with the housing 200 to form a protective space 500 having a detection port 510. The second detection mechanism 35 is located in the protective space 500, which can avoid the pollution of the second detection mechanism 35 by the oil stain in the housing 200 and ensure the detection effect with high precision of the second detection mechanism 35.

[0154] In an alternative embodiment, as Figure 26 shown, when the second detection mechanism 35 is a radar, since the radar performs 360° omnidirectional detection and the second protective cover 400 and the housing 200 are made of metal, the position covered by the second protective cover 400 and the housing 200 can achieve the effect of shielding the radar signal, which can avoid misjudgment of the radar caused by the operation of the movable part 300 and the fan 700, and improve the accurate detection of the radar when the user is in the preset area.

[0155] In an alternative embodiment, as Figure 26 shown, most of the structure of the operation panel assembly 100 is in the protective space 500, which can also avoid the pollution of the operation panel assembly 100 by the oil stain in the housing 200 and ensure the good cleanliness and normal use effect of the operation panel assembly 100.

[0156] In an alternative embodiment, as Figure 29As shown, the operation panel assembly 100 further includes a third detection mechanism 39, which is electrically connected to the controller of the range hood. The controller is also respectively communicatively connected to the movable part 300 and the blower 700 of the range hood. A cooking stove 3000 is provided below the range hood, and a cooker 2000 is provided on the cooking stove 3000. The third detection mechanism 39 is arranged on the mounting assembly 60 and is used to detect the temperature of the cooking utensil 4000 on the cooker 2000. The controller can control the working states of the movable part 300 and the blower 700 according to the temperature of the cooking utensil 4000 on the cooker 2000, so as to realize the adaptive adjustment of different working states of the range hood to the temperature of the cooking utensil 4000, and achieve a better oil fume absorption effect of the range hood.

[0157] Exemplarily, for the type of the third detection mechanism 39, this optional embodiment does not make any restrictions. For example, it can be set as an active infrared temperature sensor or a passive infrared temperature sensor. The active infrared temperature sensor emits infrared rays. After the infrared rays contact the object to be measured, they are reflected and received again by the active infrared temperature sensor to realize the measurement of the temperature of the object to be measured. The temperature measurement principle of the passive infrared temperature sensor is as follows: when the temperature of an object is higher than absolute zero, infrared rays will be radiated to the surrounding. The passive infrared temperature sensor detects the infrared radiation energy of the object to realize the detection of the temperature of the object to be measured. In addition to the above two types, any infrared temperature sensor that can realize non-contact measurement of the temperature of the object to be measured is within the protection scope of the technical solution of the present invention.

[0158] In an optional embodiment, as Figure 29 shown, a third detection mechanism 39 is provided for each cooker 2000 in a one-to-one correspondence. Each third detection mechanism 39 can accurately detect the temperature of the cooking utensil 4000 on the corresponding cooker 2000. Exemplarily, the number of the third detection mechanisms 39 can be one, two, three or more, and the number of the third detection mechanisms 39 corresponds to the number of the cookers 2000.

[0159] In an optional embodiment, as Figure 30 shown, the third detection mechanism 39 is set to two, and the cookers 2000 in this optional embodiment are set to two. Each third detection mechanism 39 corresponds to one cooker 2000 in a one-to-one correspondence, and can accurately detect the temperature of the cooking utensil 4000 on the corresponding cooker 2000 by the third detection mechanism 39.

[0160] In an optional embodiment, as Figure 30As shown in the figure, two third detection mechanisms 39 are arranged on both sides of the smoke collecting plate 320 in the left-right direction. In addition, the detection signal M emitted by each third detection mechanism 39 is located outside the smoke collecting plate 320, so as to avoid the interference of the smoke collecting plate 320 on the detection signal M and ensure the always accurate detection effect of each third detection mechanism 39 on the temperature of the cookware 4000.

[0161] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
