When the smoke collecting chamber body 310 is contracted in the housing 200 and the smoke collecting plate 320 is in the second state, a better retracting effect of the movable portion 300 can be achieved. It should be noted that, the range hood is only one type of telescopic range hood, and the range hood according to the embodiments of the present disclosure may also be various types of range hoods, such as a top-suction type range hood, a side-suction type range hood, an ultra-thin type range hood, and all types of range hoods are within the protection scope of the embodiments of the present disclosure.
As shown in fig. 1 and 3, 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 for displaying the icon 20, and a user can operate the icon 20 to realize different functions of the range hood. As shown in fig. 1 and fig. 3, the operation panel assembly 100 includes a transparent panel 10, a photoelectric assembly 30, and an icon 20, where the transparent panel 10 is directly or indirectly connected to the casing 200, the icon 20 is embedded in the transparent panel 10, the photoelectric assembly 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, and the first light emitting element 31 can realize the function of lighting the icon 20, so that the icon 20 emits light, which is convenient for a user to identify the icon 20, and is convenient for the user to accurately trigger the icon 20, thereby avoiding the user from touching the icon 20 by mistake. By way of example, the transparent panel 10 may be a transparent plastic, transparent glass, polymethyl methacrylate, etc., all transparent materials capable of being formed into a panel are within the scope of the embodiments of the present disclosure. For example, the first light emitting element 31 may be an RGB lamp, an LED lamp, or the like, and all structures capable of emitting light are within the scope of the embodiments of the present disclosure. By way of example, the icons 20 may be formed by performing a silk screen process, an etching process, a laser engraving process, etc. on the inside of the transparent panel 10 by a laser, enabling rapid processing and formation of the icons 20. In an alternative embodiment, the icon 20 is located inside the transparent panel 10, so that the icon 20 can be prevented from being polluted by external oil smoke or greasy dirt, and a better lighting and shining effect of the icon 20 is achieved all the time.
However, in the existing range hood, the brightness of the icon 20 is not obvious enough in the environment with strong light, which affects the display effect of the icon 20 on the operation panel assembly 100, and is not beneficial to the accurate identification of the icon 20 by the user in the environment with strong light, which affects the normal operation of the range hood by the user.
Through research staff's long effort research, the reason that icon 20 luminous effect is poor is mainly because the thickness of icon 20 is insufficient, and the thickness of icon 20 is insufficient to lead to light reflection relatively poor in icon 20, leads to the luminance of luminous icon 20 not obvious enough, is unfavorable for the user to the accurate discernment of icon 20 under stronger light's environment, influences the user to the normal operation of lampblack absorber.
To solve the above problem, in an alternative embodiment, as shown in fig. 13, the thickness of the transparent panel 10 is the first thickness D 1, the dimension of the icon 20 along the thickness direction of the transparent panel 10 is the second thickness D 2, where D 2/D1 is greater than or equal to 1/4 and less than 1, and the second thickness D 2 of the icon 20 is relatively large, so as to ensure that the light ray has a better reflection effect in the icon 20, ensure that the icon 20 has enough brightness, so that a user can accurately identify the icon 20 even in a strong light environment, and ensure that the user operates the operation panel assembly 100 and the range hood normally. Illustratively, D 2/D1 may be 1/4, 1/3, 1/2, etc., with the above values being merely limiting examples, and all values in the range of greater than or equal to 1/4 and less than 1 are within the scope of this alternative embodiment.
In an alternative embodiment, as shown in fig. 13, the second thickness D 2 is greater than or equal to 2mm and less than or equal to 5mm, where the second thickness D 2 of the icon 20 is greater, so that a better reflection effect of light in the icon 20 can be ensured, and sufficient brightness of the icon 20 is ensured, so that a user can accurately identify the icon 20 even in a stronger light environment, and normal operation of the operation panel assembly 100 and the range hood by the user is ensured. By way of example, it may be 2mm, 3mm, 4mm, 5mm, etc., all values in the range of greater than or equal to 2mm and less than or equal to 5mm are within the scope of this alternative embodiment.
In an alternative embodiment, as shown in fig. 13, the first thickness D 1 is greater than 2mm and less than or equal to 20mm, and the larger first thickness D 1 can achieve a better supporting effect on the icon 20 with a larger thickness, so as to avoid the damage problem of the transparent panel 10 during use.
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 formed of lines, the engraved lines have a great influence on the reflection and refraction angles of light, and in some cases, the thin lines may cause the reflection amount and refraction amount of light to be too low, thereby causing the light emitting effect of the icon 20 to be weakened.
To solve the above problem, in an alternative embodiment, as shown in fig. 28, the transparent panel 10 has a front surface 113, the projection of the icon 20 on the front surface 113 is formed by lines, the width of the lines is greater than or equal to 0.8mm and less than or equal to 1.2mm, and these relatively wider lines can provide more notches and surfaces, so that the light is more likely to be reflected and refracted at the icon 20, ensuring that the icon 20 has enough brightness, so that the user can accurately identify the icon 20 even in a stronger light environment, and ensuring that the user operates the operation panel assembly and the range hood normally. Illustratively, the width of the lines may be 0.8mm, 0.85mm, 0.9mm, 0.95mm, 1mm, 1.1mm, 1.2mm, etc., all values within the range of greater than or equal to 0.8mm and less than or equal to 1.2mm are by way of limited example only and are within the scope of this alternative embodiment.
The engraved glass generally uses high quality, transparent and impurity-free glass, and if a material of poor quality is selected, the reflectivity and refractive index of light on the surface and inside thereof are lowered, which also adversely affects the luminous effect of the icon 20.
To solve the above problem, in an alternative embodiment, the transparent panel 10 is made of super white glass, where the transmittance of the super white glass reaches 90%, and the super white glass has higher quality, higher transparency, fewer impurities and fewer defects, so that the reflectivity and refractive index of light at the icon 20 can be effectively improved, and the icon 20 is ensured to reach enough brightness, so that the user can accurately identify the icon 20 in a stronger light environment, and the normal operation of the operation panel assembly and the range hood by the user is ensured.
In an alternative embodiment, the light emitted by the first light emitting element 31 is visible light, so that the user can clearly and obviously identify the illuminated icon 20. Specifically, visible light refers to a wavelength in the range of 390nm or more and 760nm or less.
For example, the wavelength of the light emitted by the first light emitting element 31 is greater than or equal to 622nm and less than or equal to 760nm, and the light emitted by the first light emitting element 31 is red, which has a high resolution, so that the user can conveniently identify the illuminated icon at a long distance. For example, the wavelength of the light emitted by the first light emitting element 31 may be 622nm.622nm, 640nm, 660nm, 670nm, 690nm, 700nm, 720nm, 750nm, 760nm, etc., all first light emitting elements 31 capable of emitting light having a wavelength in the range of 622nm or more and 760nm or less are within the scope of this alternative embodiment, which is not exemplified.
As an alternative, the first light emitting element 31 that can emit light with a wavelength greater than or equal to 624nm may be selected, and the wavelength of the ultra-red light may be 624nm or more than that of the normal red light at about 622nm, and the ultra-red light may bypass the dust barrier more strongly in the same environment, so that it can be recognized at a longer distance. Meanwhile, the vivid red color plays a role in expanding color and has better warning effect. More importantly, the wavelength of the ultra-red light is substantially outside the perceived range of rod cells while still within the perceived range of cone cells.
In an alternative embodiment, the color of the light emitted by the first light emitting element 31 may be red (622 nm is less than or equal to wavelength is less than or equal to 760 nm), orange (597 nm is less than or equal to wavelength is less than 622 nm), yellow (577 nm is less than or equal to wavelength is less than 597 nm), green (wavelength is about 555 nm), blue (480 nm is less than or equal to wavelength is less than 492 nm), purple (350 nm is less than or equal to wavelength is less than or equal to 455 nm), white or other colors, and the color of the light emitted by the first light emitting element 31 may be adjusted according to the specific environment and the habit of the user, so as to ensure the user to have better experience of using the range hood. Of these, the human eye with normal vision is most sensitive to green light, so green light can be selected as the light emission color of the icon 20.
In an alternative embodiment, the color of the light emitted by the first light emitting element 31 is variable, specifically, the first light emitting element 31 may be adjusted according to different operation modes of the icon 20 by the user, so as to improve the interactivity between the user and the icon 20, and improve the use effect of the range hood by the user.

Through long-time exploration and research of researchers, it is found that the formation of the light bar 800 is mainly formed by mutual interference and superposition of light rays emitted by two adjacent first light emitting elements 31, in order to solve the above problems, as shown in fig. 4 and 5, the operation panel assembly 100 further comprises at least two light shielding elements 40, each light shielding element 40 corresponds to one first light emitting element 31 one by one, each light shielding element 40 is covered on the periphery of the corresponding first light emitting element 31, through the arrangement of the light shielding elements 40, the mutual interference of the light rays emitted by two adjacent first light emitting elements 31 can be effectively reduced, the light bar 800 formed by mutual interference and superposition of the light rays emitted by two adjacent first light emitting elements 31 is avoided, the better suspension sense of the icons 20 on the operation panel assembly 100 is realized, and the better display effect of the operation panel assembly 100 is ensured. In addition, through the setting of light shielding piece 40, can also effectively reduce the loss of first light-emitting component 31 emission light to guarantee that the first light-emitting component 31 emission light can all transmit to icon 20 in a large part, so that the luminance of icon 20 is higher, makes icon 20 more obvious in stronger light environment.
