For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] like Figure 1 , Figure 2As shown, the embodiment of the utility model provides a back plate of the inner cover of the range hood, including a plate body 1, the plate body having a front face 11 and a back face 12 opposite to each other. The top of the plate body 1 is provided with a first flange 13 extending toward the front face 11, and the side and bottom surfaces of the plate body 1 are provided with a second flange 14 extending toward the back face 12. In actual installation, as shown in FIG. Figure 3 As shown, the first flange 13 extends toward the range hood inner cover 2, and the second flange 14 extends toward the back side of the range hood.

[0029] The inner cover back plate of the range hood provided by the embodiment of the utility model is provided with a first flange 13 and a second flange 14 added around the plate body 1, and a press profile is added to the front end of the inner cover back plate. After the inner cover back plate and the inner cover are fixedly installed by the first flange 13 and the second flange 14, the strength of the inner cover back plate around can be strengthened and deformation after a drop test can be reduced; at the same time, since the back side 12 is prone to accumulate oil droplets, the second flange 14 is equivalent to a partition wall, which can prevent oil from leaking from the side and bottom.

[0030] The existing wall-mounted range hood inner cover back plate is a common press type, which has no oil guiding function. When the oil circuit is tested, the oil on the inner cover back plate will flow turbulently, resulting in leakage. In order to solve the above problem, in a preferred embodiment of the utility model, Figure 2 As shown, the back side 12 is provided with a raised oil guide rib 3 (which can be formed by a stamping process, and a depression is formed at a corresponding position on the front side 11), and the oil guide rib 3 has an angle with the horizontal direction, so that one end of the oil guide rib 3 is high and the other end is low. The top surface of the second flange 14 corresponding to the bottom surface of the plate body 1 has a confluence area 141, and the bottom end of the oil guide rib 3 corresponds to the confluence area 141. The back plate of the inner cover of the range hood provided in this embodiment is designed with an oil guide rib 3 on the back side 12 of the plate body, while strengthening the structural strength of the back plate, allowing the oil on the inner cover back plate to flow along the pressing (in the direction of the oil guide rib 3) and flow to the confluence area 141 of the second flange 14, so as to standardize the oil path and prevent leakage caused by oil turbulence. In combination with the second flange 14 of the inner cover back plate, oil leakage from the side and bottom can be prevented.

[0031] Specifically, if Figure 2 , Figure 3 As shown, the oil guide rib 3 includes a first oil guide rib 31 disposed in the middle of the back surface 12 and second oil guide ribs 32 disposed on both sides of the first oil guide rib 31 .

[0032] In one embodiment of the present invention, Figure 2 , Figure 3As shown, the first oil guide rib 31 is in a herringbone shape and / or an eight-shaped shape, and the first oil guide rib 31 is in a shape with a high middle part and low ends, so as to facilitate guiding the oil on the back side 12 to the direction of the confluence area 141. The two second oil guide ribs 32 are symmetrically arranged, and the second oil guide ribs 32 are in a parallelogram shape, and the second oil guide ribs 32 are inclined downward in the direction of the first oil guide rib 31. Specifically, two opposite sides of the parallelogram are in a vertical direction (with an angle of 90 degrees to the horizontal direction), and the other two opposite sides are in an acute angle with the horizontal direction, so as to facilitate guiding the oil on the back side 12 to the direction of the confluence area 141.

[0033] In one embodiment of the present invention, Figure 2 As shown, the second flange 14 corresponding to the bottom surface of the plate body 1 is provided with an oil outlet 142 to smoothly discharge the oil dropped on the second flange 14. In this embodiment, each oil guide rib 3 continuously intercepts and guides the oil layer by layer from top to bottom, guides the oil to the confluence area 141, and then discharges it from the oil outlet 142. In order to discharge the oil accumulated in the confluence area 141 in time, an oil outlet 142 is provided on the outer side of each confluence area 141.

[0034] In one embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 As shown, the first flange 13 is provided with a first recessed portion 131, and the first recessed portion 131 corresponds to the confluence area 141. The first recessed portion 131 can further enhance the structural strength of the first flange 13. Figure 2 As shown, the second flange 14 corresponding to the bottom surface of the plate body 1 is provided with a second recessed portion 143, and the second recessed portion 143 is located below the first oil guide rib 31. The second recessed portion 143 can enhance the structural strength of the second flange 14, and at the same time, the two sides of the second recessed portion 143 can guide the oil on the back side 12 to the confluence area 141 for easy discharge.

[0035] The utility model also provides a range hood, comprising the range hood inner cover back plate. Figure 3 As shown, the inner cover back plate is connected to the inner cover 2 of the range hood by rivets. After the connection, the strength of the inner cover 2 and the inner cover back plate is improved, and oil can be prevented from leaking from the edge of the inner cover back plate.

[0036] The range hood inner cover back plate and the range hood provided by the embodiment of the utility model have a first flange and a second flange added around the plate body of the inner cover back plate, and a press profile added to the front end of the inner cover back plate. After the inner cover back plate and the inner cover are fixedly installed by the first flange and the second flange, the strength around the inner cover back plate can be strengthened, and the deformation after the drop test can be reduced; at the same time, the second flange is equivalent to a partition wall, which can prevent oil from leaking from the side and bottom. The range hood inner cover back plate and the range hood provided by the embodiment of the utility model have oil guide ribs designed on the back side of the plate body of the inner cover back plate, which can strengthen the structural strength of the back plate while allowing the oil on the inner cover back plate to flow along the press profile (in the direction of the oil guide ribs) and flow to the confluence area of ​​the second flange to regulate the oil path and prevent leakage caused by oil turbulence. In conjunction with the second flange of the inner cover back plate, oil can be prevented from leaking from the side and bottom.

[0037] 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.
