Description

TECHNICAL FIELD

[0001] The utility model relates to the field of range hood, especially to a range hood capable of re-sucking overflowed oil fume. BACKGROUND

[0002] In the kitchen environment, the range hood as the key equipment to reduce oil fume pollution, its performance is directly related to the comfort of cooking environment and the health of family members. However, the traditional range hood has a significant problem in the process of sucking oil fume: when the electric flap is opened, although it can effectively guide the oil fume into the range hood, the narrow gap between the upper end of the flap and the main body of the range hood limits the re-sucking ability of the oil fume. The gap of the range hood on the market is usually about 3-5mm. The original design intention is to prevent the overflow of oil fume from the inner side of the flap, but the side effect is that the oil fume that has escaped upward from the lower end of the flap is difficult to be re-sucked through this narrow channel, resulting in the increase of the concentration of kitchen oil fume, which not only affects the air quality, but also may pose a potential threat to human health. Therefore, it is particularly important to develop a range hood that can more effectively re-suck the overflowed oil fume. SUMMARY

[0003] The technical problem to be solved and the technical task proposed by the utility model are to perfect and improve the existing technical solution, and to provide a range hood capable of re-sucking overflowed oil fume, in order to improve the sucking ability of the overflowed oil fume from the lower end of the electric flap. To this end, the utility model adopts the following technical solution.

[0004] A range hood capable of re-sucking overflowed oil fume, comprising a wind box assembly, an air outlet cover assembly arranged at the upper end of the wind box assembly, and a range hood assembly arranged at the lower end of the wind box assembly. The range hood assembly comprises a range hood main body, a smoke guide plate arranged at the lower part of the rear side of the range hood main body, and an electric flap located above the smoke guide plate. The gap distance between the upper end of the electric flap and the range hood main body after the electric flap is opened is in the range of 5-10mm. By setting the distance between the electric flap and the range hood main body after the electric flap is opened to be 5-10mm, compared with the traditional gap of 3-5mm, this improvement increases the width of the channel for re-sucking oil fume, making it easier for the overflowed oil fume from the lower end of the flap to be re-sucked from the gap, effectively reducing the concentration of kitchen oil fume and improving the purification efficiency of the range hood.

[0005] As a preferred technical means: the smoke machine body includes a vertical part and a horizontal part, the horizontal part is located at the top rear side of the vertical part, the lower rear side of the vertical part is connected with the front side of the bottom surface of the horizontal part through a unified rear inclined surface, the smoke guide plate and the electric flap are located on the inclined surface, and the maximum opening angle of the electric flap is in the range of 68-80 degrees. By designing the smoke machine body to include a vertical part and a horizontal part, and connecting the lower rear side of the vertical part with the horizontal part through a unified inclined surface, not only the oil fume guiding path is optimized, but also the smoke guide plate and the electric flap can be more reasonably arranged on the inclined surface, and the maximum opening angle of the electric flap is in the range of 65-80 degrees, so that more oil fume can be smoothly sucked into the inside of the smoke machine, and excessive diffusion of the oil fume is avoided.

[0006] As a preferred technical means: after the maximum opening angle of the electric flap is opened, the distance between the lower rear side of the electric flap and the rear side of the horizontal part of the smoke machine body is in the range of 40-60 mm. The overflow oil fume is easily blocked by the horizontal part of the smoke machine body, and is easily sucked into the gap at the upper end of the electric flap under the suction of the smoke machine, so that the re-suction capacity of the smoke machine is enhanced, and the overflow oil fume from the lower end of the flap can be effectively captured, and the oil fume escape capacity is reduced.

[0007] As a preferred technical means: the bottom of the horizontal part of the smoke machine body and the upper end of the inclined surface at the rear side of the vertical part are circularly arc transitioned, and the transition radius is in the range of 15 mm-30 mm. The large circular arc transition between the bottom of the horizontal part of the smoke machine body and the upper end of the inclined surface at the rear side of the vertical part optimizes the flow path when the overflow oil fume is sucked, reduces the vortex and residence of the oil fume in the transition area, and improves the suction effect of the smoke machine on the overflow oil fume.

[0008] As a preferred technical means: the smoke guide plate and the electric flap are made of tempered glass. The tempered glass is durable and easy to clean, and the good light transmission of the glass enables the user to more clearly observe the operation state of the smoke machine during cooking.

[0009] As a preferred technical means: the included angle between the inclined surface and the vertical plane is in the range of 15-18 degrees. The oil fume can be maximally guided to flow upward along the inclined surface, the accumulation and diffusion of the oil fume below the electric flap are reduced, and the oil fume suction efficiency of the smoke machine is improved.

[0010] As a preferred technical means: the size of the lower end of the vertical part of the smoke machine body is in the range of 88-95 mm. The small size of the lower end of the vertical part and the steep rear inclined surface make the front and rear thicknesses relatively small, so that the smoke machine is easy to be held by hand during installation, and the installation is facilitated.

[0011] Beneficial effect: by setting the distance between the opened electric turning plate and the smoke machine body as 5-10mm, compared with the traditional gap of 3-5mm, the improved gap increases the width of the channel for the oil fume to be sucked in again, so that the oil fume overflowing from the lower end of the turning plate is more easily sucked in again from the gap, effectively reduces the kitchen oil fume concentration, and improves the purification efficiency of the smoke exhaust machine.

[0015] The technical scheme of the utility model is further explained in detail in combination with the drawings of the specification.

[0016] In the description of the utility model, it should be understood that the orientation or position relationship indicated by the terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" in the description of the utility model are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, since the disclosed embodiments of the utility model can be arranged in different directions, so these orientation indicating terms are only as an illustration and should not be regarded as a limitation, for example, "upper" and "lower" are not necessarily limited to the direction opposite or consistent with the direction of gravity.

[0017] As shown in Figure 1 , 2 A smoke exhaust machine capable of sucking in the overflowing oil fume, which comprises a bellow assembly 1, an air outlet cover assembly 2 arranged at the upper end of the bellow assembly 1, and a smoke machine assembly arranged at the lower end of the bellow assembly 1, the smoke machine assembly comprises a smoke machine body 3, a smoke guide plate 4 arranged at the lower part of the rear side of the smoke machine body 3, and an electric turning plate 5 located above the smoke guide plate 4, an oil receiving box 6 is arranged at the lower end of the smoke machine body 3, and the gap distance L between the upper end of the electric turning plate 5 and the smoke machine body 3 is 8mm after the electric turning plate 5 is opened.

[0018] In order to ensure that the oil fume can be more smoothly sucked into the inside of the range hood, the range hood body 3 comprises a vertical part and a horizontal part, the horizontal part is located at the top rear side of the vertical part, the lower rear side of the vertical part is connected with the front side of the bottom surface of the horizontal part through a unified rear inclined surface, the smoke guide plate 4 and the electric flip plate 5 are located on the inclined surface, and the maximum opening angle a of the electric flip plate 5 is 70 degrees. By designing the range hood body 3 to comprise the vertical part and the horizontal part and connecting the lower rear side of the vertical part with the horizontal part through the unified inclined surface, not only is the oil fume flow path optimized, but also the smoke guide plate 4 and the electric flip plate 5 can be more reasonably arranged on the inclined surface, the maximum opening angle of the electric flip plate 5 is 70 degrees, and the oil fume can be more smoothly sucked into the inside of the range hood, while the excessive diffusion of the oil fume is avoided.

[0019] In order to reduce the oil fume escape ability, the distance H between the lower rear side of the electric flip plate 5 and the rear side of the horizontal part of the range hood body 3 is 50 mm after the electric flip plate 5 is opened to the maximum angle. The distance is relatively large, so that the overflow oil fume is easily blocked by the horizontal part of the range hood body 3 and is easily sucked into the gap at the upper end of the electric flip plate 5 under the suction of the range hood, thereby enhancing the re-suction ability of the range hood and ensuring that the oil fume overflowing from the lower end of the flip plate can be effectively captured, thereby reducing the oil fume escape ability.

[0020] The smoke guide plate 4 and the electric flip plate 5 are made of tempered glass. The tempered glass is durable and easy to clean, and the good light transmittance of the glass enables the user to more clearly observe the operation state of the range hood during cooking.

[0021] When the range hood is started, the suction inside the range hood starts to act, forming an inward airflow. At this time, the oil fume generated during cooking is first attracted by the range hood body 3 located at the lower end of the range hood assembly, and when the oil fume rises to the smoke guide plate 4, the smoke guide plate 4 guides the oil fume to flow to the smoke suction port opened by the electric flip plate 5 into the inside of the range hood under the action of the suction inside the range hood. For the oil fume overflowing from the lower rear side of the electric flip plate 5, the oil fume is blocked by the horizontal part of the range hood body 3 when rising, flows forward under the action of the suction of the range hood, and then flows into the inside of the range hood through the 8 mm gap, thereby achieving effective suction of the overflow oil fume.

[0022] In this example, the distance between the electric flip plate 5 and the range hood body 3 after the electric flip plate 5 is opened is set to 8 mm, which is larger than the gap of 3-5 mm in the traditional design, thereby increasing the channel width of the oil fume being sucked again, making the oil fume overflowing from the lower end of the flip plate more easily sucked from the gap, effectively reducing the kitchen oil fume concentration, and improving the purification efficiency of the range hood.

[0023] Example Two

[0024] Different from the above example one, in order to maximize the guide oil fume along the inclined surface upward flow, the angle between the inclined surface and the vertical plane is 17 degrees. The traditional oil fume machine guide smoke inclined surface is relatively slow, by increasing the angle of inclination, can maximize the guide oil fume along the inclined surface upward flow, reduce the accumulation and spread of oil fume below the electric turning plate 5, improve the oil fume machine oil fume efficiency.

[0025] In order to facilitate installation, the horizontal width size B of the lower end of the vertical part of the smoke machine body 3 is 92mm. The size of the lower end of the vertical part is small, and the rear inclined surface is steep, so that the front and rear thickness is relatively small, and when installing, it is easy to hold with hand, and the installation is convenient.

[0026] Example three

[0027] Different from the above example one or two, the bottom of the horizontal part of the smoke machine body 3 and the upper end of the inclined surface of the rear side of the vertical part are circularly arc transition, and the transition radius R is 20mm. The larger circular arc transition between the bottom of the horizontal part of the smoke machine body 3 and the upper end of the inclined surface of the rear side of the vertical part optimizes the flow path when the overflow oil fume is sucked, reduces the vortex and retention of the oil fume in the transition area, and improves the suction effect of the oil fume machine on the overflow oil fume.

[0028] The oil fume machine capable of re-sucking overflow oil fume shown above is a specific embodiment of the present application, which has embodied the substantial features and progress of the present application. According to the actual use needs, under the inspiration of the present application, equivalent modifications can be made in shape, structure and the like, which are all within the protection scope of the present application.
