Abstract
Description
Technical Field
[0001] The present application relates to the technical field of kitchen appliances, and in particular to a structure for visualizing escaping oil smoke and a range hood. Background Art
[0002] During the cooking process, a large amount of kitchen fumes are produced. Kitchen fumes mainly include fine particulate matter, settleable particulate matter and volatile organic compounds. These aerosol particles can cause harm to the human respiratory and cardiovascular systems, especially the elderly, children and patients with cardiopulmonary diseases, who are more sensitive to fine particulate pollution.
[0003] Therefore, preventing oil smoke from escaping is the main goal of a range hood and an important reference for users to choose a range hood. However, due to the trade-off between cost and appearance or due to technical limitations and unreasonable structural design, there are still many range hoods on the market that claim to prevent smoke from escaping, but the actual oil smoke escape is not optimistic. Because the oil smoke particles are too small, sometimes they are difficult to detect with the naked eye, causing users to inhale a large amount of fine particles without noticing, which seriously endangers their health.

It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.
[0036] An embodiment of the present application provides a structure for visualizing escaping oil smoke. Figure 1 This is a schematic diagram of a structure for visualizing escaping oil smoke provided in an embodiment of the present application. Figure 1 ,like Figure 1 As shown, the structure for visualizing escaping oil smoke includes a smoke collecting hood 1, a light emitting module 2, a dimming module 3 and a light blocking module 4. The light source is emitted by the light emitting module 2, the dimming module 3 adjusts the angle of emission of the light source to make the direction of the light source uniform, the light blocking module 4 blocks the non-parallel light in the light source and passes the parallel light in the light source, and finally forms a parallel light plane. When the oil smoke particles pass through the parallel light plane, they can be observed by the naked eye due to the Tyndall phenomenon. The user can adjust the gear of the range hood according to the amount of visible oil smoke at the parallel light plane, so as to avoid further escape of the oil smoke, reduce the oil smoke inhaled by the user, and ensure the health of the user.
[0037] Among them, Figure 1 As shown, the fume hood 1 is a structure of a range hood for collecting and absorbing oil smoke, and is usually installed on the top of a cooking area such as a stove, and covers the entire cooking area as much as possible to effectively collect the oil smoke and odor generated during the cooking process.
[0038] In a possible implementation, the light emitting module 2 is arranged above the smoke hood 1 to emit a light source. The dimming module 3 is used to adjust the angle of the light source so that the angle of the light emitted by the light emitting module 2 is consistent. The light blocking module 4 is arranged on the smoke hood 1 and below the light emitting module 2 to block the non-parallel light in the light source and pass the parallel light in the light source, and finally form a parallel light plane that manifests the escaped oil smoke.
[0039] Figure 2 This is a schematic diagram of a structure for visualizing escaping oil smoke provided in an embodiment of the present application. Figure 2 , Figure 2 As shown, the light blocking module 4 includes a light blocking groove 41 arranged on the smoke collecting hood 1, and the groove wall of the light blocking groove 41 is connected to the smoke collecting hood 1, and is used to block the non-parallel light in the light source. In the embodiment of the present application, the non-parallel light refers to the light that is not parallel to the vertical direction. Through the above arrangement, a parallel light surface with clear edges can be formed. During use, the user can observe with the naked eye that the oil smoke has a clear boundary, so as to adjust the gear of the range hood in time.
[0040] Specifically, Figure 2 As shown, the light blocking groove 41 is a through groove with upper and lower openings, and the depth of the light blocking groove 41 is greater than the width of the light blocking groove 41, and the light blocking groove 41 is a narrow groove arranged along the vertical direction. The deeper the depth of the light blocking groove 41, the better the effect of shielding non-parallel light. At this time, the light blocking groove 41 acts as a stop, blocking most of the non-parallel light above the light blocking groove 41.
[0041] In an optional embodiment, a light-transmitting block 42 is disposed in the light-blocking groove 41, and the light-transmitting block 42 is used to pass parallel light in the light source, that is, light directed vertically downward. The light-transmitting block 42 is preferably made of transparent acrylic material and has good light transmittance.
[0042] In other possible embodiments, the light blocking module 4 may also include structures such as light blocking strips arranged under the light emitting module. As long as it can play a role similar to an aperture to block the non-parallel light in the light source and pass the parallel light in the light source, the embodiments of the present application are not limited.
[0043] In the present application embodiment, Figure 2 As shown, the smoke hood 1 includes a front side close to the user, a rear side away from the user, and left and right sides located on both sides of the front and rear sides. The front, left and right sides of the smoke hood 1 are each provided with a light blocking groove 41, and the light blocking grooves 41 located on the front, left and right sides are connected. Light transparent blocks 42 are each provided in the light blocking grooves 41, and the light transparent blocks 42 in the light blocking grooves 41 located on the front, left and right sides are integrally formed.
[0044] Through the above-mentioned arrangement, the light-blocking grooves 41 arranged on three sides respectively form three light walls on the front, left and right sides, which tightly cover the cooking area, ensuring that the entire cooking area is fully covered and reducing the diffusion of oil smoke and odor; further, the light-blocking grooves 41 and the light-transmitting blocks 42 on the three sides are connected to ensure the formation of a continuous and uniform light surface, thereby effectively preventing oil smoke from escaping, especially from the turning points, and maintaining the oil smoke collection effect.
[0045] In an optional embodiment, the U-shaped light-transmitting block 42 is detachably connected to the U-shaped light-blocking groove 41. Since it is directly arranged above the cooking area, a large amount of oil smoke is easily accumulated on the light-transmitting block 42. The user can remove the light-transmitting block 42 from the light-blocking groove 41 and clean it separately.
[0046] Specifically, the light-transmitting block 42 can be bonded in the light-blocking groove 41 by gluing on the side. The bonding method has good sealing performance and prevents the oil smoke from further entering the smoke hood 1 and adhering to structures such as the light-emitting module that are difficult to clean.
[0047] Figure 3 This is a schematic diagram of a structure for visualizing escaping oil smoke provided in an embodiment of the present application. Figure 3 ,like Figure 3 As shown, in an optional embodiment, the dimming module 3 includes a dimming convex lens, which is arranged in the opening of the light-blocking groove 41 near the light-emitting module. The light emitted by the light-emitting module is relatively divergent, and the dimming convex lens can focus the light to a point, which helps to make the light closer to parallel. At the same time, the dimming convex lens can also make the divergent light more concentrated, enhance the intensity of the light passing through the light-blocking groove 41, and help the user observe the escaping oil smoke more clearly.
[0048] In an optional embodiment, the dimming convex lens is specifically configured as a strip structure with a shuttle-shaped cross-section, and installation grooves are symmetrically provided on the groove walls on both sides of the light-blocking groove 41, and the installation grooves are arranged close to the light-emitting module, and the dimming convex lens is installed in the installation grooves.
[0049] In other possible embodiments, the dimming module 3 may further include a rotation adjustment mechanism disposed on the light-emitting module, and rotating the light-emitting module to a value to irradiate downward may also serve the purpose of adjusting the angle of the light source, which is not limited in the embodiments of the present application.
[0050] Figure 4 is a schematic diagram of a light emitting module for visualizing escaping oil smoke provided in an embodiment of the present application, such as Figure 4As shown, the light-emitting module 2 includes a lamp bead 22, a lamp box 21 and a reflector 23. A light opening is provided on the lower side of the lamp box 21, the reflector 23 is arranged inside the lamp box 21, a mounting hole is provided on the reflector 23, the lamp bead 22 is arranged in the reflector 23 through the mounting hole, and the surface of the reflector 23 facing the light opening is set as a curved surface, so that the light can be reflected more concentratedly to the lower area, thereby improving the lighting effect and uniformity of the lamp bead 22.
[0051] In the embodiment of the present application, elastic buckles 211 are provided on both sides of the light opening of the lamp box 21, and clamping parts 231 are provided on both sides of the edge of the reflector 23, and the distance between the elastic buckles 211 on both sides of the lamp box 21 is smaller than the distance between the clamping parts 231 on both sides of the reflector 23.
[0052] In an optional embodiment, further, a stepped groove 212 is provided at the light opening of the lamp box 21 , and a stepped protrusion 232 is provided at the clamping portion 231 of the reflector 23 , and the stepped protrusion 232 is clamped in the stepped groove 212 .
[0053] Through the above-mentioned arrangement, the detachable arrangement of the elastic buckle 211 and the snap-on portion 231 makes it easier and more convenient to install and remove the reflector 23, which is convenient for the user to replace or clean the reflector 23 when needed, and at the same time can ensure the stability of the installation of the reflector 23 and the lamp beads 22 on the reflector 23, and maintain a stable lighting effect; the snap connection of the elastic buckle 211 and the snap-on portion 231 allows the reflector 23 to be firmly fixed on the lamp box 21, ensuring that the relative positions of the reflector 23 and the lamp beads 22 are not easily changed, thereby ensuring that the lamp beads 22 can be maintained at the expected position of the reflector 23 and are not easily moved or shaken during use.
[0054] In an optional embodiment, if Figure 5 As shown, the light-emitting module 2 is also a continuously arranged U-shaped structure, wherein the lamp box 21 and the reflector 23 are arranged as one body, and the spacing between the plurality of lamp beads 22 is roughly equal, so that after adjustment by the dimming module 3 and the light blocking module 4, a uniform and clear parallel light surface is formed around the cooking area.
[0055] Figure 6 is a schematic diagram of a range hood provided in an embodiment of the present application, such as Figure 6As shown, the range hood includes the above-mentioned structure for visualizing escaping oil smoke. Through the above-mentioned arrangement, a light source is emitted by a light emitting module arranged above the smoke collecting hood 1, and a dimming module adjusts the angle of emission of the light source to make the direction of the light source uniform. The light blocking module 4 blocks the non-parallel light in the light source and passes the parallel light in the light source, and finally forms a parallel light plane. When oil smoke particles pass through the parallel light plane, they can be observed by the naked eye due to the Tyndall phenomenon. The user can adjust the gear of the range hood according to the amount of visible oil smoke at the parallel light plane, so as to avoid further escape of oil smoke, reduce the oil smoke inhaled by the user, and ensure the health of the user.
