[0002] As an indispensable appliance in modern kitchens, range hoods primarily function to extract cooking fumes and steam, maintaining a clean kitchen environment and air quality. Because range hoods are installed at a high position, they partially obstruct existing kitchen lighting, resulting in dim lighting on the stovetop below the hood. Traditional range hoods, to avoid direct exposure to grease, are often designed not directly facing the cooking area. This means that during actual cooking, the lighting cannot effectively cover the inside of the cookware and the countertop, easily creating shadows. This affects the user's judgment of the food's color and cooking status, thus reducing the cooking experience and efficiency. Users often need to use auxiliary lighting to meet their lighting needs, causing inconvenience.

[0003] Secondly, most existing light fixtures are directly installed on the range hood panel. This requires creating an installation opening in the panel, which not only disrupts the overall continuity and aesthetics of the panel but also reduces its overall strength. Due to installation requirements, a gap exists between the light fixture and the installation opening, allowing grease and grime to accumulate, creating a hard-to-clean area and increasing the burden of cleaning and maintenance for users. Furthermore, for range hoods with integrated functions, gaps in the installation location of the touch control device can lead to insufficient sealing of the internal walls, allowing moisture or grease to enter and affecting the lifespan and operational safety of the touch control device.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. A range hood with concealed lighting function includes a housing 1. The front end of the housing 1 is provided with a smoke inlet. A smoke guide plate 2 is installed at the smoke inlet when opened and closed by a drive device. A mounting base 3 is connected to the back of the smoke guide plate 2. The mounting base 3 and the smoke guide plate 2 form a mounting cavity. A lighting device 7 is built into the mounting cavity. A slot 4 is provided at the upper end of the mounting cavity. One end of a protective seat 6 is inserted into the slot 4, and the other end extends into the housing 1. The protective seat 6 connects the mounting cavity and the housing 1. The power cord of the lighting device 7 passes through the slot 4 and the protective seat 6 in sequence and is electrically connected to the main control system in the housing 1. A clearance groove 11 is provided on the housing 1, and the protective seat 6 is movably inserted into the clearance groove 11.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown: A mounting base is connected to the back of the smoke guide plate. The mounting base and the smoke guide plate body together form a mounting cavity for receiving the light fixture. The mounting cavity is relatively closed, and the lighting device is completely placed and fixed inside the mounting cavity. It is not visible to the user from the front of the range hood panel, thus achieving the purpose of hiding the lighting device.

[0025] To power the concealed lighting unit, a slot is provided at the upper end of the mounting cavity, with a protective seat specifically designed for connection. One end of the protective seat inserts into the slot, while the other end extends into the housing. The protective seat connects the housing and the mounting cavity, forming a mounting channel. The power cord of the lighting unit passes through the slot and the protective seat sequentially, extending into the housing to connect with the main control system installed within the housing, thus enabling control and power supply to the lighting unit. The lighting unit is sealed within the mounting cavity, effectively isolating it from kitchen fumes, moisture, dust, and physical impacts, significantly improving its lifespan and reliability, and reducing its failure rate. Secondly, the lighting unit is completely hidden behind the smoke guide plate, avoiding the need for openings or protrusions on traditional panels, resulting in a smooth front panel of the range hood and significantly enhancing the overall aesthetics, achieving a concealed visual effect. Because the panel has no openings or protrusions, fumes and dust are less likely to accumulate in the installation gaps around the lighting unit, making daily cleaning of the panel simple and efficient, reducing the cleaning burden.

[0026] Furthermore, a clearance groove is provided on the housing. Since the smoke guide plate needs to open and close under the drive of the drive device, the back mounting base and protective base of the smoke guide plate also need to move accordingly. When the smoke guide plate opens and closes, the protective base can move within the clearance groove, ensuring that the power cord is not squeezed, pulled, or worn during movement, maintaining the stability and safety of the electrical connection, realizing the orderly management of the power cord, avoiding the risk of exposed or damaged power cord, and improving the safety and durability of the product.

[0027] The protective base 6 is symmetrically distributed and includes a connecting plate 61 and an extension plate 62. The connecting plate 61 and the extension plate 62 are folded together on both sides to form a protective groove, and the protective groove connects the mounting cavity and the housing 1.

[0028] like Figure 8 As shown, the protective base is symmetrical, and its structure includes a connecting plate and an extension plate. The connecting plate and extension plate fold together on both sides to form a protective groove. During installation, the protective groove connects the mounting cavity and the housing, providing a neat and enclosed path for the power cord. This provides comprehensive physical protection for the power cord, preventing it from being subjected to external friction, compression, or pulling during its movement. This further ensures the integrity and safety of the power cord, ensuring it follows a predetermined path and facilitating optimized use of the internal space of the housing, thus providing enhanced protection. Furthermore, the symmetrical design and the folded sides forming the protective groove give the protective base better structural strength and stability, allowing it to better withstand the forces exerted by the moving smoke guide plate, reducing the risk of deformation or damage and enhancing stability.

[0029] The slot 4 has a symmetrically protruding locking platform 5 on its outer side, and an inner mounting hole 51 is opened through the locking platform 5; the connecting plate 61 has an outer mounting hole 611 through its end face, the protective groove is fitted onto the outer wall of the locking platform 5, and the locking screw passes through the outer mounting hole 611 and connects with the inner mounting hole 51 in sequence to lock the protective seat 6 in the relative position of the mounting seat 3.

[0030] like Figure 6 , Figure 7 As shown: A locking platform symmetrically protrudes from the outer side of the slot, and an inner mounting hole is formed through the end face of this locking platform. Adapting to the inner mounting hole installation, an outer mounting hole is formed on the end face of the connecting plate of the protective seat. When the protective slot of the protective seat is fitted onto the outer wall of the locking platform, the outer mounting hole of the connecting plate aligns with the inner mounting hole. At this time, by using locking screws to sequentially pass through the outer mounting hole and the inner mounting hole and tighten them, the protective seat can be firmly fixed and locked onto the mounting seat, effectively preventing the protective seat from loosening during movement. This provides a reliable and stable mechanical lock for the protective seat, ensuring a stable connection between the protective seat and the mounting seat, maintaining connection reliability even during frequent opening and closing of the smoke guide plate. The screw locking method not only ensures the accurate installation position of the protective seat, effectively preventing misalignment and simplifying the assembly process, but also facilitates the disassembly and reassembly of the protective seat, improving product maintenance convenience.

[0031] The lighting device 7 includes a lamp plate 71 and a lamp cover 72 covering it. The mounting base 3 has a mounting opening 31 on its lower end face. The lamp cover 72 is snapped into the mounting opening 31. The lamp plate 71 is electrically connected to the control circuit board 8 built into the mounting cavity.

[0032] like Figure 7 As shown, the lighting device includes a lamp panel and a lampshade covering it. The lampshade protects the lamp panel and diffuses the light. A mounting opening is provided on the lower end of the mounting base, and the lampshade is snapped into this opening, facilitating lampshade removal and replacement, and enabling maintenance or upgrades of the lamp panel, thus reducing maintenance costs. The lamp panel is electrically connected to a control circuit board built into the mounting cavity, rather than directly to the main control system. This built-in control circuit board allows for more precise control of the lighting device, such as brightness adjustment and color temperature switching, while also simplifying the interface with the main control system and improving system integration efficiency. The lighting device is integrated into the mounting cavity, making full use of the limited space inside the range hood, maintaining the overall simplicity of the range hood's appearance, and enhancing its aesthetics.

[0033] A touch controller 9 is also installed on the back of the smoke guide plate 2, and the touch controller 9 is sealed and installed in the mounting cavity. This range hood has the touch controller installed in the sealed mounting cavity. The touch controller can be used to control and adjust various functions of the range hood. The touch controller is effectively protected and completely isolated from the external environment. When the user touches the corresponding area of ​​the smoke guide plate, the touch signal can penetrate the material of the smoke guide plate and be sensed by the internal touch controller, thus realizing air-touch operation. This significantly improves the reliability and stability of the touch controller and avoids the malfunction of traditional buttons due to oil seepage. Users can achieve function control by touching the smooth smoke guide plate, providing a novel and intuitive operating experience.

[0034] In summary, the lighting device in this range hood is built into the mounting cavity formed by the back of the smoke guide plate and the mounting base, making the front panel of the range hood smooth and without protrusions, improving the appearance and integrity of the panel, and solving the problems of traditional lamps or buttons damaging the appearance of the panel and easily accumulating dirt.

[0035] To ensure the long-term stable operation of the lighting device, a protective seat is provided between the mounting base and the housing. The protective seat includes a connecting plate and an extension plate, which together form a protective groove. The connecting plate is inserted into the slot in the housing. The protective groove connects the mounting cavity and the housing to form a sealed channel. The power cords of the lighting device and the touch controller pass through the slot and the protective groove in sequence and are connected to the main control system in the housing. This not only protects the power cords from the kitchen environment and external movements, but also locks the protective seat and the mounting base with a locking screw, ensuring the stability and reliability of the connection between the two.

[0036] Furthermore, a clearance groove is provided on the housing. Since the smoke guide plate needs to open and close under the drive of the drive device, the back mounting base and protective base of the smoke guide plate also need to move accordingly. When the smoke guide plate opens and closes, the protective base can move within the clearance groove, ensuring that the power cord is not squeezed, pulled, or worn during movement, maintaining the stability and safety of the electrical connection, realizing the orderly management of the power cord, avoiding the risk of exposed or damaged power cord, and improving the safety and durability of the product. Therefore, it can be widely used.
