[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A smoke guide plate installation structure for a range hood includes a smoke collection hood 1, with a smoke collection area 2 formed by an upward indentation in the center of the smoke collection hood 1. A smoke guide plate 3 is installed inside the port of the smoke collection area 2. A smoke inlet duct 4 is formed by hollowing out the periphery of the smoke guide plate 3 and the inner contour of the smoke collection area 2, and the smoke inlet duct 4 communicates with the smoke collection area 2. Mounting plates 5 are provided on both sides of the back of the smoke guide plate 3, and several smoke guide holes 51 are formed through the mounting plates 5. A protective cover 6 is provided with a protrusion in the center of the back of the smoke guide plate 3. Correspondingly, a supporting hanging plate 7 is provided on the inner wall of the smoke collection area 2, and the supporting hanging plate 7 is connected to the protective cover 6, suspending the smoke guide plate 3 within the smoke collection area 2.
[0026] In one embodiment: the smoke guide plate 3 has an installation opening 31 in the middle, and the protective cover 6 is embedded in the installation opening 31.
[0027] In one embodiment: one end of the supporting hanging plate 7 extends a lower plate 71, which covers the top of the protective cover 6 and is connected to it.
[0028] In one embodiment: the other end of the supporting hanging plate 7 extends to an upper plate 72, and correspondingly, a positioning plate 11 is provided inside the smoke collection hood 1, with the upper plate 72 covering the top of the positioning plate 11 and connecting to it.
[0029] In one embodiment: the supporting hanging plate 7, the lower mounting plate 71, and the upper mounting plate 72 are integrally stamped from metal sheets.
[0030] In one embodiment, the supporting hanging plate 7 is provided with a plurality of weight-reducing holes 73.
[0031] In one embodiment: the bottom of the protective cover 6 is hollowed out and has a receiving cavity 61, and a lamp 62 is covered and embedded in the receiving cavity 61.
[0032] In one embodiment, the outer contour of the smoke guide plate 3 is folded upward to form a flow guide plate 32.
[0033] In one embodiment, the included angle between the baffle plate 32 and the main body of the smoke guide plate 3 is less than or equal to 90°.
[0034] In one embodiment, the smoke guide hole 51 is rectangular.
[0035] In one embodiment: the smoke guide plate extends beyond the projected area of its port into the smoke collection area, with an extension width H ranging from 3mm to 35mm. Therefore, when viewed from the front, the user's view is obstructed by the smoke guide plate, preventing the interior from being directly exposed and affecting aesthetics. Furthermore, the outer contour of the extended smoke guide plate is also concealed by the smoke collection area, resulting in a cleaner and more aesthetically pleasing appearance for the range hood.
[0036] Working Principle: In this range hood, the central part of the smoke collection hood is recessed upwards to form a smoke collection area, and a smoke guide plate is installed at the port of this smoke collection area. The periphery of the smoke guide plate and the outer contour of the smoke collection area are hollowed out to form a smoke inlet duct, which connects to the smoke collection area. After the range hood starts working, the fumes enter the smoke inlet duct from the periphery of the smoke collection area and are concentrated into the smoke collection area under the guidance of the smoke guide plate. Unlike traditional narrow smoke inlet channels, in this design, the smoke inlet duct is formed around the smoke guide plate, allowing the fumes to smoothly enter the smoke collection area, improving the speed of fume entry and exhaust efficiency, and ensuring the range hood's exhaust effect.
[0037] Among them, a guide plate 32 is folded upward on the outer contour of the smoke guide plate 3, and the included angle between the guide plate 32 and the main body of the smoke guide plate 3 is less than or equal to 90°. The design of this guide plate can guide the oil fumes upward, so that the oil fumes can enter the air handling unit at the top of the smoke collection hood more smoothly.
[0038] The smoke guide plate is connected to the smoke collection hood via mounting plates on both sides of its back. To further strengthen the connection and ensure stability, a protective cover protrudes from the center of the back of the smoke guide plate. Corresponding to this protective cover, a mounting plate is installed on the inner wall of the smoke collection area. Locking screws pass through the mounting plate and connect to the protective cover and positioning plate, thus fixing the smoke guide plate to the smoke collection area and achieving a suspended installation. This multi-point fixing method ensures a more stable and stronger connection between the smoke guide plate and the smoke collection hood, reducing damage caused by vibrations from frequent use or high-pressure environments. It also avoids operating noise, effectively extending the service life of the range hood and improving its overall user experience.
[0039] Furthermore, an integrated light fixture is installed within the protective cover, adding illumination to the smoke guide plate. This not only meets the smoke extraction requirements but also provides lighting for the cooking area, enriching the range hood's functionality, satisfying users' practical needs, and enhancing its overall aesthetics and practicality. It should be noted that the protective cover in this case is installed upside down, effectively enclosing the light fixture within the cover. This effectively prevents grease from the back of the smoke guide plate from entering the light fixture, ensuring its lifespan.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
