Description

Technical Field

[0001] This utility model relates to an oil fume purification device, and more particularly to a lighting device installation structure for a range hood, as well as a range hood using the lighting device. Background Technology

[0002] Range hoods have become an indispensable kitchen appliance in modern homes. They operate on the principles of fluid dynamics, using a fan system installed inside to draw in and exhaust cooking fumes, and a filter to remove some of the grease particles.

[0003] To ensure good visibility for users during cooking, range hoods are usually equipped with lighting devices. For example, Chinese Patent Application No. 202220430498.5 discloses a range hood light, which includes a lamp housing, a light-transmitting panel on the bottom surface of the lamp housing, a light source mounting port on the top surface of the lamp housing, a support bracket inside the lamp housing near the light source mounting port, a light source plate inside the lamp housing on the support bracket, a cover plate covering the light source mounting port, and elastic buckles on the top surface of the lamp housing for mounting the light on the range hood panel and pressing down the cover plate. The elastic buckles on the top of the lamp housing enable the elastic snap-fit ​​assembly of the range hood panel.

[0004] However, this type of lighting has no sealed structure, and after long-term use, oil will inevitably seep into the inside of the lighting, affecting the lighting effect. Utility Model Content

[0005] The first technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a lighting device installation structure for a range hood that can improve sealing and prevent it from being affected by oil stains.

[0006] The second technical problem to be solved by this utility model is to provide a range hood with the above-mentioned installation structure.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a lighting device installation structure for a range hood, comprising:

[0008] Mounting plate;

[0009] A lighting device mounted on a mounting plate, the lighting device including a lampshade, the lampshade being a hollow cover with one end open;

[0010] Its features are:

[0011] The lighting device also includes a flexible lampshade covering, which is disposed on the outer periphery near the opening end of the lampshade and abuts against the mounting plate.

[0012] By using a soft, rubber-coated lampshade, the lampshade can come into contact with the mounting plate, thus creating a sealed area between the lampshade and the mounting plate, improving sealing performance, preventing oil ingress, and ensuring the normal operation of the lighting device.

[0013] Preferably, the mounting plate has a through hole, the open end of the lampshade is inserted into the through hole, and the rubber coating of the lampshade abuts against the mounting surface of the mounting plate located on the outer periphery of the through hole.

[0014] Furthermore, to facilitate the installation of the lampshade coating, the lampshade has an annular flange on its outer periphery near the opening end, and the lampshade coating is also annular and fixed to the flange.

[0015] Furthermore, the flange has a perforation, and the lampshade cover is fitted with the perforation via a Latin buckle. Since the lampshade is usually made of hard plastic, while the cover is usually made of soft plastic, the combination of the perforation and the Latin buckle improves the stability of the lampshade and its cover.

[0016] Furthermore, the outer periphery of the through hole has a flange that bends towards the lighting device. The lampshade cover and the opening end of the lampshade are located on the outer and inner sides of the flange, and the gap between the lampshade cover and the flange is not less than 3mm. This prevents capillary effect from drawing oil into the lighting device and affecting the surface luminous effect.

[0017] Furthermore, to facilitate the installation of the lampshade coating and the mounting plate, the cross-section of the lampshade coating is at least partially flared, and the larger end of the flared end abuts against the mounting surface of the mounting plate.

[0018] Furthermore, the thickness of the rubber coating on the lampshade gradually decreases from the lampshade towards the mounting plate, which facilitates deformation sealing and prevents oil ingress.

[0019] Furthermore, the lighting device also includes a pressure plate disposed on a side away from the opening end of the lampshade, the pressure plate extending along the length of the lampshade, and the pressure plate being directly or indirectly fixed to the mounting plate to press the lampshade and the mounting plate together.

[0020] Because the pressure plate presses down on the lampshade as a whole, the force is more evenly distributed and the sealing effect is better compared to fixed sections of spring clips.

[0021] Furthermore, to facilitate the positioning of the pressure plate and lampshade during installation, a positioning post is provided on the side of the lampshade facing the pressure plate, and a positioning hole is formed on the pressure plate to cooperate with the positioning post.

[0022] The first technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood, including a housing, characterized in that: it applies a lighting device mounting structure as described above, wherein the mounting plate is part of the housing.

[0023] The second technical solution adopted by this utility model to solve the second technical problem mentioned above is: a range hood, including a housing, characterized in that: it applies the lighting device installation structure as described above, the installation plate is part of the housing, the housing also includes an inner guide plate, the inner guide plate extends upward inclinedly from the installation plate, one side of the width direction of the pressure plate is fixed to the installation plate, and the other side of the width direction of the pressure plate is inserted under the inner guide plate.

[0024] Furthermore, the mounting plate has a through hole, and the open end of the lampshade is inserted into the through hole. The lampshade's rubber coating abuts against the mounting surface of the mounting plate located on the outer periphery of the through hole. The mounting surface is provided with a transition bracket, which is fixed to the pressure plate by screws. Since the pressure plate is higher than the mounting surface of the mounting plate, the transition bracket raises the fixing position of the mounting surface, facilitating the fixing of the pressure plate and the mounting plate.

[0025] Compared with the prior art, the advantages of this utility model are: by setting a soft lampshade covering, the lampshade covering can come into contact with the mounting plate, thereby making the lampshade and mounting plate mounting area a sealed area, improving the sealing performance, preventing oil ingress, and ensuring the normal use of the lighting device.

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] See Figures 1-5 A range hood includes a housing 1 and a lighting device 2 installed on the housing 1.

[0034] The lighting device 2 includes a lampshade 21, a lamp plate 22, and a light-transmitting plate 23. The lampshade 21 is a hollow cover with one open end. During installation, its open end faces the direction where illumination is needed; in this embodiment, the opening of the lampshade 21 faces downwards. The light-transmitting plate 23 is disposed at the opening of the lampshade 21, and the two can be fixed by ultrasonic welding. The lamp plate 22 is disposed inside the lampshade 21, opposite to the light-transmitting plate 23. The portion of the lampshade 21 near the outer periphery of the open end is provided with a lampshade cover 24. Preferably, the lampshade cover 24 and the lampshade 21 are integrally injection molded.

[0035] The housing 1 includes a mounting plate 11, which serves as the mounting base for the lighting device 2 and together with the lighting device 2 constitutes the mounting structure. The mounting plate 11 has a through hole 111 for the lighting device 2 to pass through from bottom to top during installation. A light-transmitting plate 23 is positioned within the through hole 111, corresponding to it. The end of the lampshade 21 used to mount the light-transmitting plate 23 is also inserted into the through hole 111. The lampshade cover 24 abuts against the mounting surface 114 of the mounting plate 11 located on the outer periphery of the through hole 111, thereby creating a sealed area between the lampshade 21 and the mounting plate 11 to prevent oil ingress.

[0036] To facilitate the installation of the lampshade cover 24, the lampshade 21 has an annular flange 212 on its outer periphery near the opening end. The lampshade cover 24 is also annular, and part of the lampshade cover 24 is fixed to the flange 212. The lampshade 21 is made of hard rubber, while the lampshade cover 24 is made of soft rubber. Therefore, the lampshade 21 and the lampshade cover 24 adopt a structure in which the flange 212 has a hollow 2121 and the lampshade cover 24 is engaged with it by a Latin buckle 241, interlocking to prevent the soft rubber from coming off and affecting the seal.

[0037] The cross-section of the lampshade cover 24 is at least partially flared, and the larger end of the flared end abuts against the mounting surface 114 of the mounting plate 11, thereby facilitating assembly and installation. The thickness of the lampshade cover 24 gradually decreases from the lampshade 21 toward the mounting plate 11, which is beneficial for deformation sealing and prevents oil ingress.

[0038] The through hole 111 of the mounting plate 11 is a flanged hole. Therefore, a flange 112 bending towards the lighting device 2 is provided on the outer periphery of the through hole 111. The lampshade cover 24 and the light-transmitting plate 23 are located on the outer and inner sides of the flange 112, and the flange 212 is located on the flange 112. The gap between the lampshade cover 24 and the flange 112 is not less than 3mm to prevent capillary effect from drawing oil into the interior of the lighting device 2 and affecting the surface luminous effect.

[0039] The lighting device 2 also includes a pressure plate 25, which is located on the side of the lampshade 21 away from the light-transmitting plate 23. The pressure plate 25 can be fixed to the mounting plate 11 by screws, clips, etc., or by cooperating with other components inside the housing 1. The pressure plate 25 extends along the length of the lampshade 21, thereby pressing the lampshade 21 and the mounting plate 11 together. In this embodiment, one side of the width direction of the pressure plate 25 (the front side in the figure) is fixed to the mounting plate 11 by screws, while the housing 1 also includes an inner guide plate 12 extending upwardly from the other side of the mounting plate 11 (the rear side in the figure), and the other side of the width direction of the pressure plate 25 is inserted below the inner guide plate 12 to prevent it from tilting upwards on one side. Since the pressure plate 25 is higher than the mounting surface 114 of the lampshade frame 11 located on the outer periphery of the through hole 111, a transition bracket 113 can be provided on the mounting surface 114 to raise the position where it is fixed to the pressure plate 25.

[0040] A positioning post 211 can be provided on the side of the lampshade 21 facing the pressure plate 25, and a positioning hole 251 is formed on the pressure plate 25. The positioning of the lampshade 21 and the pressure plate 25 can be achieved by the insertion and cooperation of the positioning post 211 and the positioning hole 251.

[0041] Compared to the spring-loaded fasteners commonly used in this field, the pressure plate 25 in this embodiment presses down on the lampshade 21 as a whole, resulting in a better sealing effect. In contrast, the spring-loaded fasteners, which are fixed in sections, may result in poor sealing due to inconsistent force and lampshade deformation.
