[0001] The utility model relates to the technical field of kitchen appliances, in particular to an inner cover of a range hood and a range hood. Background Art
[0002] Range hoods are widely used in kitchens. The temperature of the inner hood of the range hood is lower than that of the oil fume gas. Therefore, the oil fume gas collides with the inner hood and easily condenses on it, and adheres to it to produce condensed oil. The existing wall-mounted range hood glass panel is connected to the inner hood and can be opened and closed. When the glass panel is closed, the condensed oil easily flows from the inner hood surface to the back of the glass, causing oil dripping and leakage. When the glass panel is opened again, the oil on the back of the glass will drip onto the stove, causing pollution.
[0003] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content
[0004] The utility model aims to provide an inner cover of a range hood, which can make the oil on the surface of the inner cover drop into the interior of the range hood, thereby preventing oil dripping and leaking to cause pollution.
[0005] Another object of the utility model is to provide a range hood, which includes the above-mentioned range hood inner cover. No matter whether the panel of the range hood is opened or closed, the oil on the surface of the inner cover can be dripped into the range hood to prevent oil dripping and leakage to cause pollution.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A range hood inner cover comprises a cover body, which is rotatably connected to the smoke collecting hood of the range hood so that the cover body can be rotated between an open position and a closed position; a raised drainage rib is provided on the front side of the bottom surface of the cover body, and the drainage rib has a first drainage surface and a second drainage surface that are connected to each other, and the first drainage surface is located in front of the second drainage surface; when the cover body is located in the open position, the second drainage surface is inclined downward toward the direction of the smoke collecting hood, so that the angle between the second drainage surface and the horizontal plane is an acute angle; when the cover body is located in the closed position, the intersection of the first drainage surface and the second drainage surface is located inside the smoke collecting hood.
[0008] According to an embodiment of the utility model, the cover body includes a main board and a sub-board connected to both ends of the main board; the drainage rib is located on the front side of the main board, and the sub-board is rotatably connected to the smoke collecting hood.
[0009] According to an embodiment of the present utility model, the two ends of the drainage rib further have a third drainage surface, and the third drainage surface is connected to the first drainage surface and the second drainage surface at the same time.
[0010] According to one embodiment of the utility model, an air inlet is provided on the bottom surface of the cover body.
[0011] According to an embodiment of the utility model, the air inlet is triangular in shape, so that the air inlet gradually expands in a direction away from the drainage rib and gradually expands toward the central area of the cover body, and the three corners of the triangle are rounded.
[0012] According to one embodiment of the utility model, one corner of the triangle faces the front side of the cover body.
[0013] According to one embodiment of the utility model, the number of the air inlets is two.
[0014] The utility model also provides a range hood, comprising the range hood inner cover mentioned above.
[0015] According to one embodiment of the utility model, an oil collecting groove is provided in the smoke collecting hood of the range hood, and when the hood body is located in the closed position, the bottom surface of the hood body is inclined downward in a direction close to a user, and the intersection of the first drainage surface and the second drainage surface is located above the oil collecting groove; when the hood body is located in the open position, the bottom surface of the hood body is inclined downward in a direction away from the user, and the rear side of the bottom surface of the hood body is located above the oil collecting groove.
[0016] Compared with the prior art, the advantages and beneficial effects of the embodiments of the present invention are:
[0017] 1) The range hood inner cover and the range hood provided by the embodiment of the utility model, when the cover body is in the closed position, the oil on the bottom surface of the cover body flows to the drainage ribs under the action of gravity, flows to the intersection of the first drainage surface and the second drainage surface along the front side of the second drainage surface, and gathers the oil to form droplets. Since the intersection of the first drainage surface and the second drainage surface is located inside the smoke hood, the oil droplets can directly drip into the range hood, and prevent dripping onto the back of the glass panel, leaking from the gap between the glass panel and the smoke hood, and causing pollution to the outer surface of the smoke hood. When the cover body is in the open position, since the height of the second drainage surface gradually decreases from the front side to the back side, the second drainage surface forms a negative angle with the horizontal plane, and the oil droplets that have not dripped on the drainage ribs can flow back to the back side of the bottom surface of the cover body under the action of gravity, and then flow into the range hood, preventing oil dripping and leakage, causing pollution to the stove below.
[0018] 2) The range hood inner cover and the range hood provided by the embodiment of the utility model have an air inlet on the bottom surface of the cover body, which increases the air inlet area and air inlet volume, can absorb rising oil smoke in time, reduce oil smoke escape, and thus reduce oil dripping on the glass panel. At the same time, the increase in air inlet volume can reduce the motor speed, thereby also playing a role in reducing noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of the utility model provides an inner cover of a range hood, including a cover body 1, and the cover body 1 is rotatably connected to the smoke hood 2 of the range hood, so that the cover body 1 can be rotated between an open position and a closed position. For the sake of clear description, the direction of the range hood facing the user is defined as the front side, and the direction of the range hood facing the installation wall is defined as the rear side. During actual installation, a glass panel 21 is installed on the front side of the cover body 1. When the cover body 1 is in the open position, a main air inlet is formed between the glass panel 21 and the smoke hood 2 of the range hood. When the cover body 1 is in the closed position, the glass panel 21 closes the main air inlet. A raised drainage rib 3 is provided on the front side of the bottom of the cover body 1. The drainage rib 3 has a first drainage surface 31 and a second drainage surface 32 which are connected to each other. The first drainage surface 31 faces the front side of the cover body 1, and the second drainage surface 32 faces the rear side of the cover body 1. The first drainage surface 31 is located in front of the second drainage surface 32. As shown Figure 4 , Figure 5 As shown, when the hood body 1 is in the open position, the second guide surface 32 is tilted downward toward the smoke collecting hood 2, so that the height of the second guide surface 32 gradually decreases from the front side to the rear side, so that the angle between the second guide surface 32 and the horizontal plane is an acute angle. Figure 6 , Figure 7 As shown, when the hood body 1 is located at the closed position, the intersection of the first flow guiding surface 31 and the second flow guiding surface 32 is located inside the smoke collecting hood 2 .
[0032] The inner cover of the range hood provided by the embodiment of the utility model is designed with drainage ribs 3 on the front side of the bottom of the cover body 1. When the cover body 1 is in the closed position, the oil on the bottom surface of the cover body 1 flows to the drainage ribs 3 under the action of gravity, flows forward along the second drainage surface 32 to the intersection of the first drainage surface 31 and the second drainage surface 32 (the position where the drainage ribs 3 are farthest from the bottom surface of the cover body 1), and the oil is gathered to form droplets. Since the intersection of the first drainage surface 31 and the second drainage surface 32 is located inside the smoke hood 2, the oil droplets can directly drip into the range hood, and are prevented from dripping onto the back of the glass panel 21 and leaking out from the gap between the glass panel 21 and the smoke hood 2 to pollute the outer surface of the smoke hood 2. When the cover body 1 is in the open position, since the height of the second drainage surface 32 gradually decreases from the front side to the rear side, the second drainage surface 32 forms a negative angle with the horizontal plane. The oil droplets that have not yet dripped off the drainage rib 3 can flow back to the rear side of the bottom surface of the cover body 1 under the action of gravity, and then flow into the interior of the range hood, preventing oil dripping and leakage from causing contamination of the stove below.
[0033] Specifically, if Figure 1 , Figure 2 As shown, the cover body 1 includes a main board 11 and a sub-board 12 connected to both ends of the main board 11. The drainage rib 3 is located at the front side of the main board 11. Figure 3 As shown, the auxiliary plate 12 is rotatably connected to the smoke collecting hood 2 , and a glass panel 21 is fixed on the front sides of the main plate 11 and the auxiliary plate 12 .
[0034] In one embodiment of the present invention, Figure 2 As shown, the two ends of the drainage rib 3 also have a third drainage surface 33, and the third drainage surface 33 is connected to the first drainage surface 31 and the second drainage surface 32 at the same time, so that the distance between the third drainage surface 33 and the bottom surface of the cover body 1 gradually decreases from the front side to the rear side, so that when the cover body 1 is in the closed position, the oil droplets near the two ends of the drainage rib 3 are guided to the intersection of the first drainage surface 31 and the second drainage surface 32 and drip into the range hood, preventing the oil from dripping onto the back of the glass panel 21; and, when the cover body 1 is in the open position, the oil droplets near the two ends of the drainage rib 3 are guided to the rear side of the cover body 1 and drip into the range hood, preventing the oil from dripping onto the stove below.
[0035] The existing wall-mounted range hood has a small main air inlet area and poor smoke extraction effect, which causes the glass panel 21 to easily drip oil when it is in the open state (corresponding to the cover body 1 in the utility model being in the open position). In order to solve the above problem, in a preferred embodiment of the utility model, as Figure 1 , Figure 2As shown, the bottom surface of the cover body 1 is provided with an air inlet 13. By providing the air inlet 13 on the bottom surface of the cover body 1, the air inlet area and air volume are increased, the rising oil smoke can be absorbed in time, the oil smoke escape is reduced, and the oil dripping of the glass panel 21 is reduced. At the same time, the increase in air volume can reduce the motor speed, thereby also playing a role in reducing noise.
[0036] In a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the air inlet 13 is triangular, so that the air inlet 13 is gradually expanded in the direction away from the drainage rib 3 and gradually expanded in the direction close to the central area of the cover body 1. The three corners of the triangle are rounded corners with large arc transitions. The oil on the front side of the air inlet 13 can flow smoothly to the rear side of the bottom surface of the cover body 1 and drip into the range hood along this shape. Preferably, one corner of the triangle faces the front side of the cover body 1, so that the two sides corresponding to the corner have a tendency to extend from the front side of the bottom surface of the cover body 1 to the rear side, which is conducive to the oil on the front side of the air inlet 13 flowing backward along the edge of the air inlet 13 to the rear side of the bottom surface of the cover body 1.
[0037] In a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, there are two air inlets 13, which together with the main air inlet form a four-chamber air inlet, increasing the air intake. When the oil smoke rises, the four chambers smoke at the same time, which can quickly suck away the oil smoke and improve the smoking effect.
[0038] like Figure 3 , Figure 4 , Figure 6 As shown, an embodiment of the utility model further provides a range hood, comprising the range hood inner cover mentioned above.
[0039] In a preferred embodiment of the present invention, Figure 3 , Figure 6 , Figure 7 As shown, the fume collecting hood 2 of the range hood is provided with an oil receiving groove 22. When the hood body 1 is in the closed position, the bottom surface of the hood body 1 is tilted downward toward the direction close to the user, and the intersection of the first drainage surface 31 and the second drainage surface 32 is located above the oil receiving groove 22 to receive the oil drops dripping from the intersection of the first drainage surface 31 and the second drainage surface 32. When the hood body 1 is in the open position, the bottom surface of the hood body 1 is tilted downward toward the direction away from the user, and the rear side of the bottom surface of the hood body 1 is located above the oil receiving groove 22 to receive the oil drops dripping from the rear side of the hood body 1.
[0040] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
