[0029] The utility model provides a specific embodiment of a range hood, see Figure 1, including a range hood body 1, which is provided with an opening. When the range hood body 1 is installed above the stove, the opening is located on the side away from the wall, that is, on the side facing the user. The range hood body 1 includes a shell 2, and devices such as a motor and a wind wheel installed inside the shell 2. In fact, the structure of the range hood body 1 belongs to the existing technology and will not be described in detail here. A panel assembly for covering the opening is provided at the opening; the panel assembly includes an upper glass panel 3, an LED lamp 4 is provided on the inner side of the upper glass panel 3, and a light-transmitting area 5 is provided on the upper glass panel 3, the light-transmitting area 5 is opposite to the LED lamp 4, and the light of the LED lamp 4 passes through the light-transmitting area 5 and illuminates the cooking area located below the range hood body 1, wherein the method of forming the light-transmitting area 5 on the glass belongs to the existing technology, for example, opaque ink can be printed on the area of ​​the glass surface that does not need to be light-transmitted by screen printing technology to form the light-opaque area 5, and at the same time, the area that needs to be light-transmitted is left to form the light-transmitting area 5, which is used to be opposite to the LED lamp 4 so that the light of the LED lamp 4 can penetrate from the light-transmitting area 5 and illuminate the cooking area; the so-called cooking area is also the stove area, or more precisely, the area where the gas stove and other stoves are located. When the gas stove is a double stove, both stoves are located in the cooking area, that is, the light of the LED lamp 4 needs to be able to illuminate the position where the double stoves are located. Since the upper glass panel 3 is made of glass, it is easy to clean, no oil residue will remain on the glass surface, and the glass will not turn yellow, so it will not affect the passage of light from the LED lamp 4, and will not affect the brightness of the cooking area, thereby improving the user's cooking experience and, at the same time, improving the overall appearance of the range hood.

[0030] In the preferred embodiment, see Figure 2 The LED lamp 4 is in a long strip shape and is arranged along the length direction of the upper glass panel 3, and the center line of the LED lamp 4 in the vertical length direction coincides with the center line of the upper glass panel 3 in the vertical length direction, that is, the center line A of the LED lamp 4 in the vertical length direction coincides with the center line B of the upper glass panel 3 in the vertical length direction, so that the long strip LED lamp 4 can have a uniform illumination range and cover a wide cooking area. When the gas stove has two stoves, it can illuminate the pots on the two stoves, so that the user can clearly observe the cooking situation in the pots.

[0031] In the preferred embodiment, see Figure 2 The light-transmitting area 5 is long and narrow, and the width W of the light-transmitting area 5 and the diameter D of the LED lamp 4 satisfy the relationship 1 / 2D<W≤D. By controlling the width of the light-transmitting area 5 and the diameter of the LED lamp 4, the light emitted by the LED lamp 4 can be concentrated and brighter. On the basis of a sufficiently wide illumination range, sufficient brightness is further provided, improving the user experience.

[0032] In the preferred embodiment, see Figure 2 The panel assembly also includes an upper mounting plate 6, which is mounted on the open portion of the range hood body 1 and partially covers the open portion. The upper glass panel 3 is connected to the outside of the upper mounting plate 6. The upper mounting plate 6 is provided with an LED lamp mounting hole, and the LED lamp 4 is disposed in the LED lamp mounting hole and detachably connected to the LED lamp mounting hole via a connector. The upper mounting plate 6 connects the upper glass panel 3 to the range hood body 1 and also provides a mounting position for the LED lamp 4. The detachable connector secures the LED lamp 4, making it easier to replace the LED lamp 4.

[0033] In the preferred embodiment, see Figure 3 , there can be multiple connecting members, which are arranged at intervals along the length direction of the upper mounting plate 6. In this embodiment, there are three connecting members, which are elastic metal members. The elastic metal member includes a first plate body 7 connected to the upper mounting plate 6. Specifically, a first connecting plate 8 protruding toward the connecting member direction is provided on the upper mounting plate 6, and the first plate body 7 is connected to the first connecting plate 8; the elastic metal member also includes a second plate body 9, a third plate body 10 and an elastic hook 11. The first plate body 7 and the second plate body 9 are staggered up and down, and the first plate body 7 and the second plate body 9 are connected by the third plate body 10. It can be understood that the first plate body 7, the third plate body 10 and the second plate body 9 form a stepped shape; the elastic hook 11 is connected to the end of the second plate body 9, and a card hole is provided on the upper mounting plate 6. The hook 11 is engaged in the card hole, and the LED lamp 4 is limited in the LED lamp mounting hole by the third plate 10 and the second plate 9. Specifically, a second connecting plate 12 protruding toward the connecting piece is further provided on the upper mounting plate 6, and a card hole is provided on the second connecting plate 12. The free end of the elastic hook 11 is bent toward the inside of the range hood body 1. When the elastic hook 11 is engaged in the card hole, the bent area of ​​the elastic hook 11 is against the end of the card hole away from the upper glass panel 3. When the connecting piece needs to be removed, it is only necessary to manually push the elastic hook toward the side of the LED lamp 4, so that the elastic hook 11 is disengaged from the card hole, that is, the connecting piece is loosened, and the limitation of the connecting piece on the LED lamp 4 is released, and the LED lamp 4 can be replaced. The structure is simple and practical.

[0034] In the preferred embodiment, see Figure 2The panel assembly also includes a lower glass panel 13, which is connected to the range hood body 1 through a flip assembly. When the flip assembly is unfolded, the lower glass panel 13 is located above the LED lamp 4, and the opening on the range hood body 1 is partially exposed. When the lower glass panel 13 is located above the LED lamp 4, it can block the part of the light from the LED lamp 4 that directly hits the human eye, that is, the lower glass panel 13 has the function of a reflector, which not only prevents the light from directly hitting the human eye, but also makes the light that hits the lower glass panel 13 be scattered toward the cooking area below the range hood. In addition, the upper glass panel The plate 3 is located above the oil smoke suction port and plays the role of collecting smoke. That is, when the oil smoke goes upward, the lower glass panel 13 is blocked after flipping over to prevent the oil smoke from continuing to float upward, so that the range hood can absorb the oil smoke more cleanly. When the flip assembly is folded, the lower glass panel 13 is located below the LED light 4 and blocks a part of the open area on the range hood body 1. The open area is the oil smoke suction port, and a grille 14 is provided thereat. When the lower glass panel 13 is flipped downward, it can block the grille 14 to avoid exposure, which is more beautiful and prevents foreign matter from entering the range hood body 1 through the grille 14.

[0035] In the preferred embodiment, see Figure 1 、 2 and 5. The flip assembly includes a pair of flip arms, which are respectively arranged on both sides of the lower glass panel 13. One end of a single flip arm is connected to the lower glass panel 13, and the other end is rotatably connected to the range hood body 1, that is, connected to the inner side of the shell 2 of the range hood body 1; the flip assembly also includes a flip driving mechanism for driving the lower glass panel 13 to flip and connected to the range hood body 1. Specifically, the flip drive mechanism includes a rotating output shaft 15, which can be driven by a driving member 16 such as a rotating motor or a motor, and the driving member 16 is connected to the inner surface of the shell 2 of the range hood body 1. The rotating output shaft 15 is the output shaft of the driving member 16. The rotating output shaft 15 is connected to a transmission member 17 that can rotate with it. The flip drive mechanism also includes a transmission arm 18, one end of the transmission arm 18 is connected to the transmission member 17, and the two can be hingedly connected, and the other end is connected to one of the flip arms, and the two can be hingedly connected. The rotating output shaft 15 rotates to drive the transmission member 17 to rotate, and drives the flip arm to swing around the rotation point to drive the lower glass panel 13 to flip.

[0036] In the preferred embodiment, see Figure 5The flip arm includes a first arm section 19 and a second arm section 20. The end of the first arm section 19 is rotatably connected to the range hood body 1. Specifically, the end of the first arm section 19 is hinged to a hinge seat 21 fixed to the inner surface of the housing 2 of the range hood body 1. The end of the second arm section 20 is connected to the lower glass panel 13. The first and second arm sections 19, 20 are arranged at an angle. The second arm section 20 is curved, with its end bent toward the first arm section 19. The angled arrangement of the first and second arm sections 19, 20 allows the lower glass panel 13 to flip upward to position above the LED light 4, while flipping downward to completely cover the exposed grille 14 and position itself below the LED light 4. This structure simplifies the flipping mechanism of the lower glass panel 13.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
