Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a range hood with ambient lighting. Background Technology

[0002] Currently, high-end furniture and kitchen appliances often incorporate ambient lighting to enhance their perceived quality. For range hoods, ambient lighting is frequently placed on the upper part of the switch panel, making the entire panel illuminated, a common feature in European brands. Alternatively, it can be placed in the darker areas on the sides and back, as seen in the Vatti J689AHE product, to improve the overall ambiance. For top-mounted range hoods with a movable smoke-collecting plate at the front, the open plate can create a sense of confinement; ambient lighting is an effective solution to avoid this feeling.

[0003] Currently, there are no ambient lights on range hoods that are mounted on the movable smoke collection plate and move with it. Furthermore, mounting ambient lights on the movable smoke collection plate presents the following problems: 1. The smoke collection plate is a moving part, making it difficult to wire the light strip, and the reliability of the wire must be ensured under repeated movement of the smoke collection plate; 2. The space formed by the movement trajectory of the smoke collection plate and the inner cavity of the smoke hood is narrow, making it difficult to arrange the light strip; 3. The ambient light strip is a relatively precise electrical component, and its assembly and fixation with the smoke collection plate is difficult to guarantee under mass production; 4. A uniform and bright light strip needs to be formed on the edge of the smoke collection plate, and there should be no patterns formed by the 422 beam angle of the LED beads on the front. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a range hood with ambient lighting, which can improve the overall atmosphere and solve the problem of the oppressive feeling caused by the opening of the smoke collection plate in top-mounted range hoods.

[0005] The range hood with ambient lighting described above is achieved through the following technical solution:

[0006] A range hood with ambient lighting includes a smoke collection hood, which further includes a light-transmitting panel, an ambient lighting assembly, and a drive assembly mounted on the smoke collection hood. The light-transmitting panel is movably disposed on the smoke collection hood and connected to the output end of the drive assembly. The ambient lighting assembly includes a housing and an LED light panel. The housing is engaged with the light-transmitting panel and together define a mounting cavity S. The LED light panel is mounted in the mounting cavity S and has a gap H between it and the light-transmitting panel, and the light emission direction of the LED light panel is towards the light-transmitting panel.

[0007] In some embodiments, the housing is U-shaped with an opening on one side, the housing engages with the edge of the light-transmitting plate and together define the mounting cavity S, and a limiting portion extending toward the mounting cavity S is provided on the inner side of at least one side wall of the housing, the limiting portion being located between the LED light panel and the light-transmitting plate.

[0008] In some embodiments, the limiting portion is provided on the inner side of the outer shell away from the smoke hood, and the distance L between the edge of the outer shell away from the smoke hood and the limiting portion is not less than 11mm.

[0009] In some embodiments, the ambient light assembly further includes a seal disposed on the inner side of at least one side wall of the housing, the seal abutting against the light-transmitting plate.

[0010] In some embodiments, the outer casing has an outwardly recessed groove on the inner side wall corresponding to the seal, and the seal is a sponge strip with an adhesive surface, the sponge strip being adhered to the inner side wall and covering the opening of the groove; or, the outer casing has an outwardly recessed groove on the inner side wall corresponding to the seal, the seal is a sealing strip, the sealing strip having a positioning part facing the groove, the positioning part engaging with the groove.

[0011] In some embodiments, the LED light board has printed circuits, and the housing has an outwardly recessed groove at a position corresponding to the printed circuits, the groove communicating with the mounting cavity S.

[0012] In some embodiments, the light-transmitting plate is a flip-up glass, which is rotatably connected to the smoke collection hood via an opening and closing assembly. The opening and closing assembly is connected to the output end of the drive assembly. The outer shell has a notch at the position corresponding to the opening and closing assembly, and the notch communicates with the mounting cavity S to limit the opening of the opening and closing assembly.

[0013] In some embodiments, the periphery of the flip glass is provided with a frosted structure, and / or the outer surface of the outer shell is provided with a protective layer.

[0014] In some embodiments, the ambient light assembly further includes a connecting wire, the housing is provided with a wire passage opening communicating with the mounting cavity S, the opening and closing assembly is provided with a wire passage channel, the smoke collection hood is provided with a wire passage hole, one end of the connecting wire is connected to the LED light board, and the other end passes through the wire passage opening, the wire passage channel and the wire passage hole in sequence and is then connected to a power supply located inside the smoke collection hood.

[0024] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific embodiments of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solutions claimed in the present invention.

[0025] See Figure 1-6This embodiment provides a range hood with ambient lighting. Taking a top-mounted range hood as an example, the top-mounted range hood includes a smoke collection hood 1, a light-transmitting plate 2, an ambient lighting assembly 3, and a drive assembly 5 installed on the smoke collection hood 1. The bottom of the smoke collection hood 1 is provided with a smoke inlet (not shown in the figure). The light-transmitting plate 2, as a smoke gathering plate, is movably disposed at the smoke inlet of the smoke collection hood 1 and connected to the output end of the drive assembly 5, so as to realize the opening and closing movement of the light-transmitting plate 2 by the drive assembly 5. The ambient lighting assembly 3 includes a housing 31 and an LED light panel 32. The housing 31 is snapped onto the light-transmitting plate 2 to allow for quick assembly and disassembly between the housing 31 and the light-transmitting plate 2. The housing 31 and the light-transmitting plate 2 together define a mounting cavity S. The LED light panel 32 is installed in the mounting cavity S with a gap H between it and the light-transmitting plate 2. This gap H is not less than 0.4 mm, and the light emission direction of the LED light panel 32 faces the light-transmitting plate 2. This protects the LED light panel 32 from impacts and oil fume contamination from the light-transmitting plate 2. At the same time, the gap H of not less than 0.4 mm ensures the heat dissipation effect of the LED light panel 32. When the LED light panel 32 is working, due to the light-transmitting characteristics of the light-transmitting plate 2, a light strip is formed on the light-transmitting plate 2, thereby giving the range hood a better ambient lighting effect. This improves the overall atmosphere and solves the problem of a feeling of oppression when the smoke collection plate of a top-mounted range hood is opened.

[0026] As can be seen, the range hood of this embodiment, by setting an LED light panel 32 and a housing 31 around the LED light panel 32 on the light-transmitting plate 2 that can be opened and closed, and setting the light emission direction of the LED light panel 32 to face the light-transmitting plate 2, is simple and reliable to assemble, does not require glue to fix it, and can form a light strip on the light-transmitting plate 2 when the LED light panel 32 is working, so that the range hood has a better sense of ambient light, which improves the overall atmosphere and solves the problem of the oppressive feeling caused by the opening of the smoke collection plate of the top smoke hood.

[0027] See Figure 3 and Figure 6 Specifically, the outer casing 31 is U-shaped with an opening on one side. It consists of two opposing side walls 3101 forming the front and back sides, and a connecting surface 3102 connecting the two side walls 3101. During installation, the outer casing 31 engages with the edge of the light-transmitting plate 2 and together define the mounting cavity S. In this way, the outer casing 31 protects the LED light panel 32 located inside and decorates the appearance of the light-transmitting plate 2, creating conditions for the rapid assembly of the LED light panel 32 and solving the problem of the narrow space formed by the movement trajectory of the light-transmitting plate 2 and the inner cavity of the smoke hood 1, making it difficult to arrange. Preferably, the outer casing 31 is made of aluminum metal to give it the properties of aluminum metal. In addition, a protective layer is provided on the outer surface of the outer casing 31. This protective layer can be formed by oxidation, electroplating, painting, etc., and the protective layer can be made in different colors as needed.

[0028] In this embodiment, the outer casing 31 is engaged with the upper edge of the light-transmitting plate 2. This allows the LED light panel 32 to project a uniform and bright light band around the edge of the light-transmitting plate 2, ensuring uniform brightness at the edge and creating a good ambient lighting effect. Furthermore, it ensures that the LED light panel 32 can operate for over 30,000 cycles during the overall opening and closing lifespan of the unit, maintaining stable and reliable operation. In this embodiment, the upper edge of the light-transmitting plate 2 specifically refers to the edge of the light-transmitting plate 2 closest to the smoke hood 1 when it is open.

[0029] Specifically, a limiting part 311 extending toward the mounting cavity S is provided on the inner side of at least one side wall 3101 of the housing 31. The limiting part 311 is located between the LED light panel 32 and the light-transmitting plate 2, and is used to limit the installation of the light-transmitting plate 2, ensuring that the defined mounting cavity S has a sufficiently large space while effectively preventing the light-transmitting plate 2 from colliding with the LED light panel 32.

[0030] In this embodiment, when the light-transmitting plate 2 is in the closed state, the side wall 3101 of the outer shell 31 facing away from the smoke hood 1 is the front side of the outer shell 1, and the side wall 3101 of the outer shell 31 facing away from the smoke hood 1 is the back side of the outer shell 1. Preferably, a limiting part 311 is provided on both the front and back sides of the outer shell 1, and the length of the front side of the outer shell 1 is greater than the length of the back side of the outer shell 1. More preferably, the beam angle of the LED light panel 32 is 102°, and the distance L between the edge of the front side of the outer shell 31 and the limiting part 311 is not less than 11mm, thus ensuring that the front side of the outer shell 31 can block the mesh-like light path formed by the beam angle of the LED light panel 32.

[0031] See Figure 3 Furthermore, the ambient light assembly 3 also includes a seal 33. The seal 33 is provided on the inner side of at least one side wall 3101 (i.e., the front and / or back) of the housing 31. The seal 33 abuts against the light-transmitting plate 2. In this way, the setting of the seal 33 increases the friction between the housing 31 and the light-transmitting plate 2 on the one hand, and improves the sealing performance of the mating point between the light-transmitting plate 2 and the housing 31 on the other hand, preventing water and oil from entering the mating point.

[0032] In this embodiment, the sealing element 33 is preferably a sponge strip with an adhesive surface. The front of the outer casing 31 has an outwardly recessed groove 312 at the position corresponding to the sponge strip. The sponge strip is adhered to the inner side of the front of the outer casing 31 and covers the opening of the groove 312. This securely connects the sealing element 33 to the inner side of the front of the outer casing 31, preventing water and oil from entering at the mating point between the front of the outer casing 31 and the light-transmitting plate 2. Furthermore, due to the presence of the groove 312, the sponge strip, after being adhered, will recess towards the inside of the groove 312, thus forming a wavy shape. This increases the friction with the light-transmitting plate 2, further strengthening the installation stability of the outer casing 31 and preventing the ambient light assembly from detaching. In other embodiments, the sealing element 33 can be preferably a sealing strip. The front of the outer casing 31 has a groove 312 at the position corresponding to the sealing strip. The sealing strip has a positioning part facing the groove 312, which engages with the groove 312. This positions the sealing strip, ensuring a more stable structure after installation and further enhancing the sealing effect.

[0033] See Figure 2-3 Specifically, the LED light board 32 includes a PCB board 321 and a plurality of LED beads 322. The side of the PCB board 321 facing away from the light-transmitting plate 2 has printed circuits. The plurality of LED beads 322 are installed side by side at intervals on the side of the PCB board 321 facing the light-transmitting plate 2. The beam angle of each LED bead 322 is 120°. This ensures that the beam generated by the LED beads 322 is directed toward the light-transmitting plate 2, so that a uniform and bright light band is formed around the edge of the light-transmitting plate 2. Specifically, the connecting surface 3102 of the housing 31 has an outwardly recessed gap groove 313 at the position corresponding to the printed circuit. The gap groove 313 is connected to the mounting cavity S, thus forming an electrical clearance and reasonably avoiding the printed circuits on the PCB board 321.

[0034] In this embodiment, the length of the PCB board 321 is less than the length of the outer casing 31, and the length of the PCB board 321 is approximately 750 mm. The number of LED beads 322 is preferably 54, arranged side-by-side at intervals on the PCB board 321 and facing the light-transmitting plate 2. To ensure soft light, the power of the LED light board 32 is controlled to within 3W. In other embodiments, the number of LED beads 322 can be adaptively adjusted according to the length of the outer casing 31.

[0035] See Figure 1 and Figure 5-6 Preferably, the light-transmitting plate 2 is a flip-type glass with a frosted structure on all four edges. This frosted structure on the side facing the LED 322 helps reduce the beam pattern caused by the beam angle, while the frosted structures on the other three sides scatter the light, resulting in a uniform and bright edge light band. Alternatively, in other embodiments, a resin light guide material can be added between the flip-type glass and the LED 322 to further enhance the light diffusion effect and make the light more uniform.

[0036] Furthermore, it also includes two opening / closing components 4 and a driving component 5. The flip glass and the smoke hood 1 are rotatably connected through the two opening / closing components 4. Inside the smoke hood 1, there is a driving component 5 connected to the opening / closing components 4. The driving component 5 is used to drive the opening / closing components 4 to perform opening and closing movements, and the movement of the opening / closing components 4 can drive the opening and closing movements of the flip glass. In this embodiment, the driving component 5 includes two mounting brackets 51, a fixed base 52, and a motor (not shown in the figure). One end of the two mounting brackets 51 is connected to the two opening / closing components 4 respectively, and the other end is connected to the smoke hood 1. A fixed base 52 is provided on one of the mounting brackets 51. The output end of the motor is connected to the mounting bracket 51 through the fixed base 52, so that the motor can drive the mounting bracket 51 to move, and thus the movement of the mounting bracket 51 can synchronously drive the opening / closing components 4 to perform opening and closing movements.

[0037] Specifically, it also includes a flip-up glass backing plate 6, which is disposed on the side of the light-transmitting plate 2 facing the opening and closing assembly 4 (i.e., the back side of the light-transmitting plate 2). The side of the flip-up glass backing plate 6 closest to the outer casing 31 extends into the interior of the outer casing 31, thereby clamping the side of the flip-up glass backing plate 6 closest to the outer casing 31 between the back side of the outer casing 31 and the light-transmitting plate 2, ensuring a more stable installation of the flip-up glass backing plate 6. The opening and closing assembly 4 is connected to the back side of the light-transmitting plate 2 through the flip-up glass backing plate 6. The outer casing 31 has a notch 314 at the position corresponding to the opening and closing assembly 4, which connects to the mounting cavity S and is used to limit the opening of the opening and closing assembly 4.

[0038] See Figure 3-6 Furthermore, the ambient light assembly 3 also includes a connecting wire 34. The housing 31 has a wire passage 315 at the position corresponding to the opening and closing assembly 4, which connects to the mounting cavity S. This wire passage 315 is used for the connecting wire 34 to pass through and also serves as a glue application point. The opening and closing assembly 4 has a wire passage channel 41, and the smoke hood 1 has a wire passage hole (not shown in the figure). One end of the connecting wire 34 is connected to the LED light board 32, and the other end passes through the wire passage 315, the wire passage channel 41, and the wire passage hole in sequence before connecting to the power supply located inside the smoke hood 1. Thus, by providing a wire passage channel 41 on the opening and closing assembly 4 and passing the connecting wire 34 through the wire passage channel 41, when the mounting bracket 51 is connected to the opening and closing assembly 4, it can fix the connecting wire 34 and ensure that the connecting wire 34 can move with the opening and closing movement of the opening and closing assembly 4, effectively solving the problem of difficult wiring of the connecting wire 34.

[0039] Specifically, the connecting wire 34 includes an FPC wire 341, a silicone-insulated wire 342, a heat-shrink tubing 343, and a terminal block 344. One end of the FPC wire 341 is connected to the LED light board 32, and the other end passes through the wire port 315 and the wire passage 41 before connecting to the silicone-insulated wire 342. This ensures that the FPC wire 341 is not easily broken, effectively guaranteeing its reliability under repeated movement, and thus ensuring the service life of the connecting wire 34. The end of the silicone-insulated wire 342 away from the FPC wire 341 passes through the wire port and connects to the power supply. The heat-shrink tubing 343 is fitted on the outer surface of the connection between the FPC wire 341 and the silicone-insulated wire 342 to protect the connection between them.

[0040] Preferably, a protective structure is provided at the mating point between the connecting wire 34 and the wire passage 315. The protective structure is a cured adhesive, used to prevent the connecting wire 34 from breaking at the wire passage 315, further enhancing the reliability of the FPC wire 341 under repeated movement. In addition, protective structures are also provided at both ends of the housing 31 to seal both ends of the housing 31, thereby improving the oil and water resistance of the ambient light assembly 3 and preventing the LED light board 32 from being contaminated by oil and water.

[0041] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
