Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] Since the lights of range hoods are mostly directly exposed inside the smoke collection chamber of the smoke collection hood, during the long-term operation of the range hood, the oil that condenses on the inner wall of the fan box and / or the surface of the volute is prone to dripping onto the surface of the lights along the direction of gravity, which leads to the decrease in the light efficiency of the lights, difficulty in cleaning, and the risk of short circuits.

[0003] Therefore, related technologies use independent oil-proof covers or tilted lampshades to prevent oil from dripping directly onto the surface of the lighting lamp. However, these solutions suffer from problems such as complex structure and inconvenient installation. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] According to embodiments of the present invention, such as Figures 1 to 7 As shown, a range hood is provided, including: a smoke collection hood 10, a front panel 11 on the front side of the smoke collection hood 10, a lighting device 200 mounted on the front panel 11, and an oil collection mesh 100 arranged at intervals above the lighting device 200 inside the smoke collection hood 10. The oil collection mesh 100 has a blocking part 110 for blocking the lighting device 200 and a mesh part 120 for air outlet. The projection of the lighting device 200 in the vertical direction is located within the range of the blocking part 110.

[0030] In this embodiment, a front panel 11 is provided on the front side of the fume hood 10. The front panel 11 serves as a mounting carrier, allowing the lighting device 200 to be mounted on it. The lighting device 200 mounted on the front panel 11 provides illumination to the cooking area, allowing users to clearly see the cooking status of the food on the stove. An oil collection mesh 100 is spaced above the lighting device 200. The shielding portion 110 of the oil collection mesh 100 shields the lighting device 200, preventing direct contamination by oil and maintaining a relatively clean operating environment, thereby extending the lifespan of the lighting device 200. Simultaneously, the oil collection mesh 100 also has perforated portions 120 for air outlet, allowing fumes to be smoothly drawn into the range hood without affecting the normal smoke extraction function of the oil collection mesh 100.

[0031] Furthermore, the lighting device 200 is configured such that its projection along the vertical direction is located within the area of ​​the shielding part 110, ensuring that the shielding part 110 can completely cover the projection area of ​​the lighting device 200 on its plane. This prevents oil stains falling from above the fume hood 10 from directly contaminating the lighting device 200, further protecting it and extending its service life. Moreover, the range hood provided by this invention has a simple structure, integrating the oil fume protection of the lighting device into the oil collection screen, eliminating the need for additional complex independent oil separators or inclined lampshades, thereby reducing assembly steps and lowering production costs.

[0032] like Figure 6 As shown, in one embodiment, the blocking part 110 is a solid plate-shaped structure, and the mesh part 120 is provided with a plurality of mesh holes 121 arranged at intervals along the left and right directions of the oil collecting net 100, and each mesh hole 121 is provided with a retaining edge 1211 extending upward from the upper surface of the oil collecting net 100; the blocking part 110 is located on the front side of the oil collecting net 100, and the mesh part 120 is located on the rear side of the oil collecting net 100.

[0033] In this embodiment, the shielding part 110 is located on the front side of the oil collecting net 100, and the shielding part 110 adopts a solid plate structure, which can block oil from splashing directly onto the lighting device 200 below the oil collecting net 100 to the greatest extent. The mesh part 120 is located on the rear side of the oil collecting net 100, and by arranging a plurality of mesh holes 121 at intervals along the left and right direction of the oil collecting net 100, the oil collecting net 100 has enough channels to allow oil fumes to enter the fume collection chamber smoothly. The baffle 1211 extending upward from the upper surface of the oil collecting net 100 around each mesh hole 121 allows oil to flow along the baffle 1211 to the surface of the oil collecting net 100, so that the oil can flow along the baffle 1211 and the surface of the oil collecting net 100, and finally be collected by the oil cup, so as to achieve efficient filtration and flow guidance.

[0034] In one embodiment, the oil collecting net 100 has an upwardly extending first flange 130 on the front side and both sides in the left and right directions, and a downwardly extending second flange 140 on the rear side. The rear side of the oil collecting net 100 is connected to the inner wall of the rear side of the smoke hood 10 through the second flange 140, and the front side of the oil collecting net 100 is connected to the inner wall of the front side of the smoke hood 10 through the corresponding first flange 130.

[0035] In this embodiment, the first flange 130 on the front side of the oil collecting mesh 100 extends upward and connects to the inner wall of the front side of the fume hood 10, while the second flange 140 on the rear side of the oil collecting mesh 100 extends downward and connects to the inner wall of the rear side of the fume hood 10. This allows the oil collecting mesh 100 to be securely installed inside the fume hood 10, while also providing some reinforcement to the range hood housing. Furthermore, the downward-extending second flange 140 can guide the oil intercepted by the oil collecting mesh 100 downward, allowing the oil to flow along the second flange 140 to the oil cup or other oil collecting devices at the bottom rear side of the fume hood 10, making the oil flow path smoother and preventing oil from flowing and accumulating randomly inside the fume hood 10. By providing the first flange 130 on both sides of the oil collecting mesh 100 in the left-right direction, oil can be prevented from escaping through the edge gaps of the oil collecting mesh 100, and oil spillage from the oil collecting mesh 100 can also be prevented.

[0036] Understandably, in order for the oil to flow better on the oil collection screen 100, the installation height of the front side of the oil collection screen 100 is higher than the installation height of the rear side of the oil collection screen 100, so that the oil collection screen 100 has a certain tilt angle when installed on the smoke hood 10.

[0037] like Figure 2 As shown, in one embodiment, it also includes a bellows and a fan assembly disposed within the bellows. The fan assembly includes a volute 201, with an oil hole 2011 at the bottom of the volute 201. The oil collecting screen 100 is also provided with an oil receiving portion 150 for receiving oil droplets from the oil hole 2011. The oil receiving portion 150 is disposed directly below the oil hole 2011 and located in the solid area between two adjacent mesh openings 121. The orthographic projection of the oil hole 2011 on the oil collecting screen 100 is within the range of the oil receiving portion 150.

[0038] In this embodiment, the fan assembly inside the air box specifically includes a volute 201 and a motor 202 and an impeller 203 disposed within the volute 201. Through the combined action of the motor 202, impeller 203, and volute 201, the range hood can effectively draw in cooking fumes and exhaust them outdoors. During the operation of the impeller 203, some condensed oil droplets will form inside the volute 201; by providing an oil hole 2011 at the bottom of the volute 201, the condensed oil droplets inside the volute 201 can be discharged through the oil hole 2011, thus preventing excessive oil accumulation inside the volute 201 and affecting the performance of the fan assembly.

[0039] An oil-receiving part 150 is provided on the oil collecting mesh 100. The oil-receiving part 150 is located directly below the oil hole 2011 and within the solid area between two adjacent mesh holes 121, which ensures that oil stains fall accurately onto the oil-receiving part 150. At the same time, the orthogonal projection of the oil hole 2011 on the oil collecting mesh 100 is within the range of the oil-receiving part 150, ensuring that all oil stains are received by the oil-receiving part 150 without any oil leakage. This effectively collects the oil stains discharged from the volute 201 and prevents oil stains from dripping directly onto the stove or kitchen utensils through the mesh part 120, thus avoiding a bad user experience.

[0040] In one embodiment, the mesh portion 120 is provided with sub-mesh 122 at both ends of the oil receiving portion 150 in the front-rear direction, which are consistent with the extension direction of the mesh 121. Each sub-mesh 122 is provided with a sub-edge 1221 extending upward from the upper surface of the oil collecting mesh 100 on its periphery.

[0041] In this embodiment, sub-mesh holes 122 are provided at both ends of the mesh portion 120 in the front-rear direction of the oil receiving portion 150, so that the extension direction of the sub-mesh holes 122 is consistent with that of the mesh holes 121. This allows for a further increase in the air intake area of ​​the oil collecting mesh 100 without affecting the normal oil receiving function of the oil receiving portion 150, thereby ensuring the smoke collection effect of the range hood. By providing sub-edges 1221 extending upward from the upper surface of the oil collecting mesh 100 around each sub-mesh hole 122, it is possible to prevent oil stains in the fumes from dripping directly from the edge of the sub-mesh hole 122 to the bottom, and also to guide the oil stains along the sub-edges 1221 to the upper surface of the oil collecting mesh 100 near the rear, and then collect them in the oil cup of the range hood.

[0042] In one embodiment, a quick-release oil filter 300 is provided at the air inlet of the fume hood 10, and the total air inlet area of ​​the quick-release oil filter 300 is smaller than the total air inlet area of ​​the oil filter 100.

[0043] In this embodiment, the air inlet of the fume hood 10 is the entrance for oil fumes to enter the fume hood 10. The quick-release oil filter 300 is installed at the air inlet of the fume hood 10, which can perform preliminary filtration of oil fumes as soon as they enter the fume hood 10. Setting the total air inlet area of ​​the oil filter 100 to be larger than the total air inlet area of ​​the quick-release oil filter 300 can make the exhaust of oil fumes smoother and facilitate the rapid absorption of oil fumes into the fume collection chamber, thereby improving the user experience.

[0044] like Figure 3 , Figure 4 As shown, in one embodiment, the front panel 11 of the cover is provided with a mounting socket 113 and a pair of limiting steps 111 located on opposite sides of the mounting socket 113 and folded toward the oil collection screen 100; the lighting device 200 is snapped into the mounting socket 113 and abuts against the limiting steps 111, and the bottom of the lighting device 200 does not exceed the lower surface of the front panel 11 of the cover.

[0045] In this embodiment, a mounting slot 113 is provided on the front panel of the housing. A pair of limiting steps 111 are formed by folding the front and rear opposite sides of the mounting slot 113 toward the oil collection screen 100. When the lighting device 200 is installed in the mounting slot 113 by snap-fit, the lighting device 200 abuts against the limiting steps 111, thereby determining the position of the lighting device 200 on the front panel 11 of the housing; moreover, the limiting steps 111 also play a role in positioning and limiting, ensuring that the lighting device 200 is installed in the correct position and will not move or shake at will.

[0046] When the lighting device 200 is installed in the mounting socket 113, the bottom of the lighting device 200 does not exceed the lower surface of the front panel 11 of the cover, thus ensuring the neatness and aesthetics of the overall appearance of the range hood. This allows the lighting device 200 to form a unified whole with the front panel 11, preventing it from protruding from the lower surface of the front panel 11 and affecting the overall shape and installation space of the range hood. Simultaneously, it prevents the lighting device 200 from being bumped or damaged during use, and facilitates the smooth flow of fumes near the front panel 11, avoiding airflow turbulence caused by the protruding lighting device 200.

[0047] In one embodiment, the lighting device 200 includes a light-emitting panel 210 and a cover 220, which are connected by an ultrasonic process, and the cover 220 protrudes into the smoke hood 10.

[0048] In this embodiment, ultrasonic technology refers to using high-frequency vibration energy to connect two objects together. The process of connecting the light-emitting panel 210 and the cover 220 using ultrasonic technology includes using ultrasonic welding equipment to transmit high-frequency vibration energy to the connection points of the light-emitting panel 210 and the cover 220 through an ultrasonic transducer. The high-frequency vibration causes the material molecules at the connection point to move violently, and the friction between the molecules generates heat, causing the material surface to reach its melting or softening point. Under pressure, the softened materials fuse together. When the vibration stops, the material cools and solidifies, thus achieving a firm connection between the light-emitting panel 210 and the cover 220. Using ultrasonic connection ensures the reliability and sealing of the connection between the light-emitting panel 210 and the cover 220, effectively preventing oil fumes from entering the lighting device 200, thereby ensuring the normal operation of the lighting device 200 and effectively extending its service life. The cover 220 protrudes into the fume hood 10 to prevent the lighting device 200 from extending beyond the lower surface of the front panel 11 of the cover, further preventing the lighting device 200 from being impacted or damaged during use.

[0049] In one embodiment, the lighting device 200 further includes an elastic connector 112, a pair of limiting steps 111 having an abutment portion 114, the elastic connector 112 being mounted on the cover 220 and abutting against the abutment portion 114.

[0050] In this embodiment, the elastic connector 112 is installed on the top of the cover 220. The elastic connector 112 also has a connecting through hole, allowing for bolt connection to further fix the elastic connector 112 to the cover 220. An abutment portion 114 is provided on a pair of limiting steps 111, extending upwards from the upper surface of the limiting steps 111. When the lighting device is snapped into the mounting socket 113, the elastic connector 112 abuts against the side wall of the abutment portion 114 facing the cover 220, thereby achieving a fixed connection of the lighting device. If it is necessary to remove the lighting device from the mounting socket 113, pressing both ends of the elastic connector 112 causes it to elastically deform, separating the elastic connector 112 from the side wall of the abutment portion 114, thus completing the disassembly of the lighting device.

[0051] like Figure 7 As shown, in one embodiment, the top of the cover 220 is provided with a pair of limiting protrusions 230, and each elastic connector 112 is disposed within a pair of limiting protrusions 230.

[0052] In this embodiment, a pair of limiting protrusions 230 extend upward from the top surface of the sub-cover 220; when the lighting device 200 is snapped onto the front panel 11 of the cover, the elastic connector 112 is snapped between the pair of limiting protrusions 230 to ensure that the elastic connector 112 can be accurately installed in the designated position and will not shift or shake during use, thereby ensuring the accuracy and stability of the installation of the lighting device 200.

[0053] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0054] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
