Description

Technical Field

[0001] The utility model belongs to the technical field of range hoods, and in particular relates to a range hood. Background Art

[0002] A range hood is a common kitchen appliance used to purify the kitchen environment. It quickly extracts and discharges the exhaust gas generated by the gas stove and the fumes generated during cooking to purify the kitchen air and improve the cooking comfort of users. Range hoods are usually divided into two types: top suction type and side suction type. Side suction range hoods are becoming more and more popular among consumers because the fume outlet is closer to the source of the fume and the suction and exhaust effects are stronger. At present, the air inlet of most side suction range hoods is set at the top of the range hood. Although it has a large smoke collection range, the fume outlet is far away from the stove, and it is difficult to generate sufficient negative pressure near the stove, and the fume absorption effect is limited to a certain extent.

[0003] The existing Chinese patent with announcement number CN111006291A discloses a range hood, including a shell and a fan system arranged in the shell, the lower part of the shell has a vertically extending smoke inlet chamber, the front side wall and / or the bottom wall of the lower part of the shell are provided with a smoke inlet port connected to the smoke inlet chamber, the upper part of the shell has a smoke collecting chamber connected to the smoke inlet chamber, the smoke collecting chamber extends forward to form an installation chamber for installing the fan system, and the shell corresponding to the bottom of the installation chamber is provided with an upper air intake port connected to the installation chamber.

[0004] The above-mentioned range hood has a smoke inlet on the front side wall and / or bottom wall of the lower part of the shell, and the smoke inlet is close to the smoke generating position, so the smoke extraction effect is better. However, when the user uses a multi-layer cookware, the height of the multi-layer cookware is relatively high, and the movement trajectory of the smoke baffle at the smoke inlet interferes with the multi-layer cookware, which is easy to overturn the cookware. In view of this, how to design a range hood technology that can be close to the smoke generating position of the cookware while avoiding the risk of overturning the cookware is a technical problem to be solved by the utility model. Summary of the invention

[0005] The utility model provides a range hood which can be close to the smoke generating position of a cooker and can avoid the risk of lifting the cooker.

[0006] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0060] In one aspect, combining Figures 1 to 7 As shown, an embodiment of the present disclosure provides a range hood, which includes a fume collecting hood 1, a lower flap assembly 2 and a driving mechanism 3.

[0061] Combination Figure 2 As shown, a smoke collecting chamber 11 is formed inside the smoke collecting hood 1, and a smoke inlet 12 is provided at the lower portion of the smoke collecting hood 1, and the smoke inlet 12 is connected to the smoke collecting chamber 11;

[0062] The lower flap assembly 2 can be opened and closed at the smoke inlet 12; when the user is cooking, the lower flap assembly 2 opens the smoke inlet 12, and when the user does not need to cook, the lower flap assembly 2 closes the smoke inlet 12, which can avoid the internal structure of the smoke hood 1 from being exposed and improve the overall aesthetics.

[0063] Combination Figure 2and Figure 3 As shown, one end of the driving mechanism 3 is connected to the smoke hood 1, and the other end of the driving mechanism 3 is connected to the lower flap assembly 2. The driving mechanism 3 is configured to drive the upper end of the lower flap assembly 2 to move away from or close to the smoke inlet 12 to achieve the opening and closing of the smoke inlet 12.

Since the lower flap assembly 2 flips downward, even if the height of the cookware is high, there is no interference between the movement trajectory of the lower flap assembly 2 and the cookware, thereby preventing the lower flap assembly 2 from overturning the cookware; at the same time, since the position of the smoke inlet 12 is relatively low, the smoke inlet 12 is closer to the smoke emission position of the cookware, and the smoking effect is better.

[0066] Specifically, the range hood also includes a front panel, which is arranged on the upper part of the smoke collecting hood 1, the front panel is connected to the smoke collecting chamber 11, a sealing box is provided in the front panel, the sealing box is provided with a smoke extractor, a decorative cover is provided on the outer side of the front panel, a panel is provided at the front end of the smoke collecting hood 1, an LED lamp is provided below the panel, and an LED lampshade is provided on the outer side of the LED lamp; a button switch is provided on the panel.

[0067] Combination Figure 4 As shown, in some embodiments of the present application, the lower flap assembly 2 includes a main board portion 21 and a support portion 22 .

[0068] Combination Figure 5 As shown, the main board portion 21 is made of glass material, which facilitates daily cleaning and maintenance of the main board portion 21. The main board portion 21 is adapted to the smoke inlet 12. When the main board portion 21 is in a closed state, the main board portion 21 completely covers the smoke inlet 12;

[0069] Combination Figure 6 As shown, the support portion 22 is fixedly disposed on the back side of the main board portion 21 , and the support portion 22 is rotatably connected to the driving mechanism 3 , and the driving mechanism 3 is used to drive the support portion 22 to rotate, so as to drive the main board portion 21 to flip.

[0070] Specifically, by setting the main board part 21 and the supporting part 22, the main board part 21 is adapted to the smoke inlet 12. When the user does not need to cook, the main board part 21 is closed to avoid the oil cavity inside the smoke hood 1 from being exposed. The appearance is neat and tidy, easy to clean, and the aesthetics is improved; the supporting part 22 is fixedly arranged on the back side of the main board part 21, and the supporting part 22 is rotatably connected to the driving mechanism 3. The driving mechanism 3 drives the supporting part 22 to rotate, driving the main board part 21 to flip, so as to facilitate opening and closing the smoke inlet 12.

[0071] Combination Figure 7 As shown, in some embodiments of the present application, when the lower flap assembly 2 is completely flipped over to open the smoke inlet 12 , the main board portion 21 is in a horizontal position.

[0072] Specifically, by setting the lower flap assembly 2 to be completely flipped open the smoke inlet 12, the main board portion 21 is in a horizontal position, which can prevent the lower flap from blocking the smoke from entering the smoke inlet 12. At the same time, the smoke inlet 12 is completely oriented toward the smoke-generating position, so that the smoke can better enter the smoke collection chamber 11 through the smoke inlet 12, thereby optimizing the air environment in the kitchen.

[0073] Combination Figure 4 As shown, in some embodiments of the present application, the support portion 22 includes a bottom plate 221 and two side plates 222 .

[0074] The bottom plate 221 is attached to the back of the main board portion 21. Specifically, the bottom plate 221 and the main board portion 21 are fixedly connected by gluing or fasteners.

[0075] The two side panels 222 are fixedly connected to the two ends of the bottom plate 221 respectively. Specifically, the two side panels 222 and the bottom plate 221 are an integrally formed structure, or a split structure. The side panels 222 are rotatably connected to the driving mechanism 3. When the main board part 21 opens the smoke inlet 12, the side panels 222 close the gap between the bottom plate 221 and the smoke hood 1.

When the main board portion 21 opens the smoke inlet 12, the side plates 222 close the gap between the bottom plate 221 and the smoke hood 1. In this way, when the main board portion 21 is flipped down, the oil smoke entering the smoke inlet 12 can be blocked from escaping toward the two sides of the smoke inlet 12.

[0077] Combination Figure 1 and Figure 4 As shown, in some embodiments of the present application, the range hood further includes an oil net 4.

[0078] The oil net 4 is a sheet-like structure with a plurality of rectangular holes formed thereon. The oil net 4 is disposed on the upper surfaces of the bottom plate 221 and the side plate 222. The oil net 4 is used for allowing oil smoke to pass through. When the main plate 21 opens the smoke inlet 12, the two side plates 222, the bottom plate 221 and the oil net 4 together enclose an outward-turned cavity.

[0079] Specifically, by setting the oil net 4, the oil net 4 is set on the upper surface of the bottom plate 221 and the side plate 222. When the main plate 21 opens the smoke inlet 12, the two side plates 222, the bottom plate 221 and the oil net 4 together enclose to form an outward-turned cavity, so that the position of the smoke inlet 12 extends forward and is closer to the smoke-generating area.

[0080] Specifically, during use, when the oil smoke airflow passes through the oil net 4 and blows toward the everted cavity, the rectangular holes can block the debris that enters the everted cavity with the oil smoke, preventing the debris from reaching the smoke collecting cavity 11 with the oil smoke, making it safer to use. The oil net 4 is tilted, and the bottom end of the oil net 4 is directly or indirectly connected to the oil receiving box 5, so that the oil can flow downward along the oil net 4 until it enters the oil receiving box 5, preventing the oil from accumulating on the oil net 4 and causing excessive wind resistance.

[0081] The main functions of the oil net 4 are as follows: first, to separate the oil fumes, the oil net 4 can effectively intercept the particles and impurities in the oil fumes, reduce the pollution of pollutants in the oil fumes to the indoor air, and protect people's respiratory health; second, to maintain the operation of the equipment, the oil net 4 can reduce the oil droplets remaining in the turbine inside the range hood, the inner wall of the smoke collection chamber 11 and the smoke pipe, maintain the efficient operation of the fan, and avoid malfunctions caused by the accumulation of oil pollution; third, to improve the oil fume absorption effect, the mesh holes of the oil net 4 have a positive effect on the smoke collection ability of the range hood, which helps to absorb the oil fume more efficiently; fourth, to condense the oil fume, the oil net 4 can condense the oil fume, so that the oil fume and water vapor can be combined to more easily flow into the oil collection box 5 at the bottom; fifth, safety protection, the oil net 4 can effectively prevent large objects and human fingers, hair, etc. from being sucked into the range hood.

[0082] In some embodiments of the present application, the oil net 4 is magnetically connected to the bottom plate 221 and the side plate 222 .

[0083] Specifically, by magnetically connecting the oil net 4 with the bottom plate 221 and the side plate 222, it is convenient and quick to install and disassemble, easy to clean, and has a good filtering effect, and can effectively remove grease particles in the oil smoke.
