[0090] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and implementation methods. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0091] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0093] In the description of the embodiments of the present disclosure, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0094] like Figure 1 , Figure 2 , Fig.26 as well as Fig.30 As shown, the present embodiment provides an oil fume treatment device, which can be a range hood, an integrated stove, etc. The present disclosed embodiment is described by taking a range hood as an example, the range hood includes a shell 200, a fan 700 and a movable part 300, wherein the fan 700 is arranged inside the shell 200, the movable part 300 includes a smoke collecting chamber body 310 and a smoke collecting plate 320, the smoke collecting chamber body 310 can extend or retract relative to the shell 200, a smoke inlet 3101 is provided on the smoke collecting chamber body 310, the smoke collecting plate 320 is arranged on the smoke collecting chamber body 310, and the smoke collecting plate 320 can switch between a first state of opening the smoke inlet 3101 and a second state of blocking the smoke inlet 3101. Fig.30As shown, when the smoke collecting chamber body 310 extends out of the shell 200 and the smoke collecting plate 320 is in the first state, the oil smoke passes through the smoke inlet 3101, the interior of the smoke collecting chamber body 310 and the shell 200 in sequence and is discharged. When the smoke collecting chamber body 310 is retracted in the shell 200 and the smoke collecting plate 320 is in the second state, a better retraction effect of the movable part 300 can be achieved. It should be noted that the aforementioned range hood is only one type of retractable range hood, and the range hood of the embodiment of the present disclosure can also be various types of range hoods such as top suction type, side suction type, ultra-thin type, etc., and all types of range hoods are within the protection scope of the embodiment of the present disclosure.

[0095] like Figure 1 and Figure 3 As shown, the range hood further includes an operation panel assembly 100, which is disposed on a housing 200 and is used to display icons 20. A user can operate the icons 20 to implement different functions of the range hood. Figure 1 and Figure 3 As shown, the operation panel assembly 100 includes a transparent panel 10, an optoelectronic assembly 30 and an icon 20, wherein the transparent panel 10 is directly or indirectly connected to the housing 200, the icon 20 is embedded in the transparent panel 10, the optoelectronic assembly 30 includes a first light-emitting component 31, the transparent panel 10 includes a light-entering surface 114 and a light-emitting surface 112, the first light-emitting component 31 is arranged on one side of the light-entering surface 114, the first light-emitting component 31 is arranged opposite to the corresponding icon 20, and the first light-emitting component 31 can realize the function of lighting up the icon 20, so that the icon 20 emits light, which is convenient for the user to identify the icon 20, and is convenient for the user to accurately trigger the icon 20, avoiding the user from accidentally touching the icon 20. Exemplarily, the transparent panel 10 can be transparent plastic, transparent glass, polymethyl methacrylate, etc., and all transparent materials that can be made into panels are within the protection scope of the embodiments of the present disclosure. Exemplarily, the first light-emitting component 31 can be an RGB lamp, an LED lamp, etc., and all structures that can realize light emission are within the protection scope of the embodiments of the present disclosure. For example, the icon 20 can be formed by a laser screen printing process, an etching process, a laser engraving process, etc. on the inside of the transparent panel 10, so as to realize rapid processing and formation of the icon 20. In an optional embodiment, the icon 20 is located inside the transparent panel 10, which can also prevent the icon 20 from being polluted by external oil smoke or oil, so as to realize a good luminous and shining effect of the icon 20 at all times.

[0096] However, in the existing range hoods, in a strong light environment, 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 user's accurate identification of the icon 20 in a strong light environment, and affects the user's normal operation of the range hood.

[0097] Through a long period of hard research and study by R&D personnel, it was found that the main reason for the poor luminous effect of icon 20 is that the thickness of icon 20 is not enough. The insufficient thickness of icon 20 leads to poor reflection of light in icon 20, resulting in the brightness of the luminous icon 20 not being obvious enough, which is not conducive to the user's accurate identification of icon 20 in a strong light environment, affecting the user's normal operation of the range hood.

[0098] To solve the above problem, in an optional embodiment, as Fig.13 As shown, the thickness of the transparent panel 10 is the first thickness D1, and the dimension of the icon 20 along the thickness direction of the transparent panel 10 is the second thickness D2, wherein D2 / D1 is greater than or equal to 1 / 4 and less than 1, and the second thickness D2 of the icon 20 is relatively large, which can ensure a good reflection effect of light in the icon 20, and ensure that the icon 20 reaches sufficient brightness, so that the user can also achieve accurate recognition of the icon 20 in a strong light environment, and ensure the user's normal operation of the operation panel assembly 100 and the range hood. Exemplarily, D2 / D1 can be 1 / 4, 1 / 3, 1 / 2, etc. The above values ​​are only limited examples, and all values ​​within the range of greater than or equal to 1 / 4 and less than 1 are within the protection scope of this optional embodiment.

[0099] In an optional embodiment, if Fig.13 As shown, the second thickness D2 is greater than or equal to 2 mm and less than or equal to 5 mm. The second thickness D2 of the icon 20 is relatively large, which can ensure a good reflection effect of light in the icon 20 and ensure that the icon 20 reaches sufficient brightness, so that the user can also accurately identify the icon 20 in a strong light environment, and ensure the user's normal operation of the operation panel assembly 100 and the range hood. Exemplarily, it can be 2 mm, 3 mm, 4 mm, 5 mm, etc. All values ​​within the range of greater than or equal to 2 mm and less than or equal to 5 mm are within the protection range of this optional embodiment.

[0100] In an optional embodiment, if Fig.13 As shown, the first thickness D1 is greater than 2 mm and less than or equal to 20 mm. The larger first thickness D1 can achieve a better supporting effect for the thicker icon 20 and avoid the transparent panel 10 from being damaged during use.

[0101] In the prior art, the transparent panel 10 includes a front surface 113 and a rear surface 115 arranged along the front-to-back direction. The projection of the icon 20 on the front surface 113 is composed of lines. The carved lines have a great influence on the reflection and refraction angles of light. In some cases, thin lines may cause the reflection and refraction of light to be too low, thereby weakening the luminous effect of the icon 20.

[0102] To solve the above problem, in an optional embodiment, as Fig.28 As shown, the transparent panel 10 has a front surface 113, and the projection of the icon 20 on the front surface 113 is composed of 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 notches 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 the user can also accurately identify the icon 20 in a strong light environment, ensuring the user's normal operation of the operation panel assembly and the range hood. Exemplarily, the width of the line 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.

[0103] 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 be reduced, which will also have a negative impact on the luminous effect of icon 20.

[0104] To solve the above problem, in an optional embodiment, the transparent panel 10 is made of ultra-white glass. The light transmittance of ultra-white glass reaches 90%. Ultra-white glass has higher quality, higher transparency, fewer impurities and fewer defects. It can effectively improve the reflectivity and refractive index of light at the icon 20, ensuring that the icon 20 reaches sufficient brightness, so that the user can accurately identify the icon 20 even in a strong light environment, and ensure the user's normal operation of the operation panel assembly and the range hood.

[0105] In an optional embodiment, the light emitted by the first light emitting element 31 is visible light, which is convenient for the user to clearly identify the luminous icon 20. Specifically, visible light refers to a wavelength greater than or equal to 390nm and less than or equal to 760nm.

[0106] Exemplarily, the wavelength of the light emitted by the first light-emitting component 31 is greater than or equal to 622nm and less than or equal to 760nm, and the light emitted by the first light-emitting component 31 is red light, and red light has a high degree of 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 component 31 may be 622nm. 622nm, 640nm, 660nm, 670nm, 690nm, 700nm, 720nm, 750nm, 760nm, etc. All first light-emitting components 31 that can emit light with a wavelength greater than or equal to 622nm and less than or equal to 760nm are within the protection scope of this optional embodiment, and this optional embodiment is no longer listed one by one.

[0107] As an optional solution, a first light-emitting element 31 that can emit light with a wavelength greater than or equal to 624nm can be selected. Compared with the wavelength of ordinary red light at around 622nm, the wavelength of super red light can reach 624nm or above. Under the same environment, super red light has a stronger ability to bypass dust barriers and can be identified at a farther distance. At the same time, brighter red has a better expansion color and warning effect. More importantly, the wavelength of super red light basically leaves the perception range of rod cells, while still within the perception range of cone cells.

[0108] In an optional embodiment, the color of the light emitted by the first light emitting element 31 can be red (622nm≤wavelength≤760nm), orange (597nm≤wavelength<622nm), yellow (577nm≤wavelength<597nm), green (wavelength is about 555nm), blue (480nm≤wavelength<492nm), purple (350nm≤wavelength<455nm), white or other colors. The color of the light emitted by the first light emitting element 31 can be adjusted according to the specific environment and the user's habits to ensure that the user has a better experience of using 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 luminous color of the icon 20.

[0109] In an optional embodiment, the color of the light emitted by the first light-emitting element 31 is variable. Specifically, the first light-emitting element 31 can be adjusted according to the different operation modes of the icon 20 by the user, thereby improving the interactivity of the user's control over the icon 20 and improving the user's use of the range hood.

[0110] In the prior art, such as Figure 3As shown, in order to realize the control of different functions of the range hood, the icon 20 is set to at least two, and at least two icons 20 are arranged at intervals along the left-right direction (i.e., the first direction), and each icon 20 is set in a one-to-one correspondence with a first light-emitting component 31. The first light-emitting component 31 and the icon 20 are arranged along the up-down direction (i.e., the second direction). Each first light-emitting component 31 can make the one-to-one corresponding icon 20 illuminate, but when two adjacent first light-emitting components 31 are illuminated, a light strip 800 will be displayed in the area between the two adjacent first light-emitting components 31 on the transparent panel 10. The light strip 800 affects the floating feeling when the icon 20 on the transparent panel 10 is illuminated, and affects the display effect of the operation panel assembly 100.

[0111] After a long period of exploration and research, the researchers found that the formation of the light strip 800 is mainly due to the mutual interference and superposition of the light emitted by two adjacent first light-emitting elements 31. In order to solve the above problem, Figure 4 and Figure 5 As shown, the operation panel assembly 100 further includes at least two shading members 40, each shading member 40 corresponds to a first light emitting member 31, and each shading member 40 is disposed on the outer periphery of the corresponding first light emitting member 31.

In addition, by disposing the shading members 40, the loss of the light emitted by the first light emitting member 31 can be effectively reduced to ensure that most of the light emitted by the first light emitting member 31 can be transmitted to the icon 20, so that the brightness of the icon 20 is higher, and the icon 20 is more obvious in a strong light environment.

The light emitted by the first light-emitting component 31 can enter the transparent panel 10 from the light incident surface 114 with minimal loss, and can also further improve the brightness of the icon 20, so that the icon 20 is more obvious in a strong light environment.

Through the provision of the first partition 82, mutual interference between different groups of probe assemblies 321 can be avoided, and each group of probe assemblies 321 can accurately detect the user operation of the corresponding icon 20. In addition, since multiple groups of probe assemblies 321 share one first protective cover body 81, the structure of the first protective cover 80 is simple and the overall parts of the operation panel assembly 100 are relatively few.

[0150] As an optional embodiment, Fig.14As shown, the first protective cover body 81 includes a positioning protrusion 811, and a positioning hole 641 is opened on the sealing member 64.

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, so that the probe assembly 321 can recognize the finger 600 trigger icon 20.

[0153] In an optional embodiment, if Fig. 9 , Fig.19 , Fig. 20 and Fig.21 As shown, the operation panel assembly 100 further includes a lens assembly 90, which includes a plurality of plano-convex cylindrical lenses 91 arranged in the left-right direction, and the focal line L of the plano-convex cylindrical lens 91 is a Extending 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 in parallel with the front surface 113 of the transparent panel 10. The convex surface 912 is located in front of the plane 911 and is bent toward the transparent panel 10. Due to the optical characteristics of the plano-convex cylindrical lens 91, from the user's perspective, the light strip 800 observed by the user on the convex surface 912 is pulled into an extremely thin strip.

It should be noted that the substrate 92 and the transparent panel 10 can be adhered by optical adhesive, and the substrate 92 and the plurality of plano-convex cylindrical lenses 91 can be integrally formed or adhered by optical adhesive.

Exemplarily, the second optical adhesive layer 95 can be made of adhesives such as organic silicone, acrylic resin, unsaturated polyester, polyurethane, epoxy resin, etc., and all types of optical adhesives are within the protection scope of this optional embodiment.

[0159] In an optional embodiment, if Fig.24 and Fig.25 As shown, the lens assembly 90 includes a lens module 93, which is arranged between two adjacent first light-emitting components 31 along the left-right direction. Each lens module 93 only hides the corresponding light strip 800. The lens assembly 90 as a whole requires less material, which can effectively reduce the cost of the operating panel assembly 100.

[0160] In an optional embodiment, if Fig.24 and Fig.25 As shown, the lens module 93 has a center line L extending in the up-down direction. C The two adjacent first light emitting elements 31 are symmetrically arranged on the center line L C On both sides, the distance between two adjacent first light-emitting members 31 along the left-right direction is a first distance S1, and the distance between two adjacent lens modules 93 along the left-right direction is a second distance S2, wherein S2 / S1 is greater than or equal to 0.4 and less than or equal to 1. It can ensure that the lens module 93 has a good shielding effect on the corresponding light strip 800. Exemplarily, S2 / S1 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.

[0161] In an optional embodiment, if Fig.15 As shown, the optoelectronic component 30 further includes a second light emitting element 34, and the transparent panel 10 further includes a light emitting surface 112. The second light emitting element 34 is disposed on one side of the light incident surface 114. The light emitted by the second light emitting element 34 can make the light emitting surface 112 emit light, and the second light emitting element 34 can achieve the effect of an ambient light. Specifically, as Fig.15 and Fig.26As shown, the operation panel assembly 100 further includes a second detection mechanism 35. The second detection mechanism 35 and the second light-emitting element 34 are electrically connected to the controller of the range hood, respectively. 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 element 34 to emit light, thereby realizing the interaction between the second light-emitting element 34 and the user operation. For example, Fig.15 As shown, the optoelectronic assembly 30 further includes a second circuit board 36, the second light emitting element 34 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.

[0162] like Figure 15 to Figure 17 As shown, the light incident surface 114 and the light emitting surface 112 are arranged between the front surface 113 and the rear surface 115, and the light emitting 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 they are parallel, if the incident angle of the light inside the transparent panel 10 exceeds a certain value, total reflection will occur, and the light will not be refracted until it is reflected to the side edge. Therefore, the side edge of the transparent panel 10 will be brighter, and the overall luminous effect of the light emitting surface 112 is poor, and a good ambient light effect of the operation panel assembly 100 cannot be achieved.

[0163] To solve the above problem, in an optional embodiment, as Fig.15 As shown, the light emitting surface 112 is a frosted surface, which can increase the refraction and reflection of the light emitted by the second light emitting component 34.

Exemplarily, the angle between two adjacent sub-side surfaces 11211 can be 20°, 30°, 40°, 50°70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. The aforementioned angles are only exemplary, and all angles are within the protection scope of this optional embodiment.

[0167] In an optional embodiment, if Fig.17 As shown, the sub-side surface 11211 includes a connecting arc surface that bends toward the inside of the transparent panel 10. The setting of the connecting arc surface can further increase the refraction and reflection intensity of light between the sub-side surfaces 11211, further enhance the overall luminous effect of the light-emitting surface 112, and further improve the ambient light effect of the operating panel assembly 100.

[0168] In an optional embodiment, if Fig.15 As shown, the light-emitting surface 112 also includes a transition arc surface 1122, and two adjacent side surfaces 1121 are connected by the transition arc surface 1122.

In addition, the setting of the transition arc surface 1122 can further increase the refraction and reflection intensity of the light on the light-emitting surface 112, further enhance the overall luminous effect of the light-emitting surface 112, and further improve the ambient light effect of the operation panel assembly 100.

[0169] In an optional embodiment, if Fig.15 As shown, the second light-emitting element 34 and the light incident surface 114 are arranged at intervals along the direction in which the second light-emitting element 34 emits light. The second light-emitting element 34 can increase the illumination range, reduce the dark area, and achieve uniform light emission of the light-emitting surface 112 at various positions. At the same time, the second light-emitting element 34 can be visually hidden.

[0170] In an optional embodiment, if Fig.15As shown, the operation panel assembly 100 also includes a light shading hood 38, on which a light channel 381 is opened, and the second light-emitting component 34 is arranged in the corresponding light channel 381.

[0172] In an optional embodiment, if Fig.15 As shown, the operation panel assembly 100 also includes a concave lens 37, which is arranged between the second light-emitting component 34 and the light incident surface 114, and can increase the irradiation range of the light emitted by the second light-emitting component 34, reduce the dark area, and achieve uniform light emission of the light-emitting surface 112 at various positions.

[0173] In an optional embodiment, the second light-emitting component 34 and the first light-emitting component 31 emit different colors of light, thereby avoiding light crosstalk between the light emitted by the second light-emitting component 34 and the light emitted by the first light-emitting component 31, ensuring the normal lighting of the icon 20, and ensuring that the light-emitting surface 112 always has a good ambient light effect.

[0174] For example, the first light emitting element 31 can be a blue light source, and the second light emitting element 34 can be a white light source, which can achieve a better distinction between the color of the icon 20 and the color of the ambient light, ensuring that the color of the icon 20 is more obvious. It should be noted that the second light emitting element 34 and the first light emitting element 31 can also be selected from other different combinations of colors, which can also achieve the above effect.

[0177] In an optional embodiment, if Fig.26 As shown, when the second detection mechanism 35 is a radar, since the radar has 360° all-round detection, the second protective cover 400 and the shell 200 are made of metal, and the position covered by the second protective cover 400 and the shell 200 can achieve the effect of shielding the radar signal, which can avoid the misjudgment of the radar due to the operation of the movable part 300 and the fan 700, and improve the radar's accurate detection of the user in the preset area.

[0178] In an optional embodiment, if Fig.26 As shown, most of the structures of the operation panel assembly 100 are in the protective space 500, which can also prevent the oil in the shell 200 from contaminating the operation panel assembly 100, thereby ensuring good cleanliness and normal use of the operation panel assembly 100.

[0179] In an optional embodiment, if Fig.29 As shown, the operation panel assembly 100 further includes a third detection mechanism 39, which is electrically connected to the controller of the range hood, and the controller is also respectively connected to the movable part 300 and the fan 700 of the range hood. A stove 3000 is arranged below the range hood, and a stove 2000 is arranged on the stove 3000. The third detection mechanism 39 is arranged on the mounting assembly 60 and is used to detect the temperature of the pot 4000 on the stove 2000.

The active infrared temperature sensor emits infrared rays, which are reflected after contacting the object to be measured and are received by the active infrared temperature sensor again to measure 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 the object is higher than the thermodynamic zero, infrared rays will radiate to the surroundings, and the passive infrared temperature sensor detects the infrared radiation energy of the object to detect the temperature of the object to be measured. In addition to the above two types, any infrared temperature sensor that can achieve 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.

[0181] In an optional embodiment, if Fig.29 As shown, each stove 2000 is provided with a third detection mechanism 39 in a one-to-one correspondence, and each third detection mechanism 39 can accurately detect the temperature of the pot 4000 on the corresponding stove 2000.

In addition, the detection signal M emitted by each third detection mechanism 39 is located on the outside of the smoke collecting plate 320, thereby avoiding interference of the smoke collecting plate 320 with the detection signal M, thereby ensuring that each third detection mechanism 39 always accurately detects the temperature of the cookware 4000.
