[0037] like Figure 4 As shown, the bellows cover 17 provided by this utility model is installed on the front side of the top of the bellows assembly, and a filter screen is installed on the rear side of the top of the bellows assembly.
[0038] The bellows cover 17 includes: a plate body, which is roughly rectangular in shape, with its length direction being the left-right direction and its width direction being the front-back direction.
[0039] like Figure 1 As shown, the top surface of the plate is provided with a downward recessed groove 1, which extends in the left and right direction. The end of the groove 1 is provided with an oil leakage hole 3. Below the oil leakage hole 3, an oil drain channel can be provided in the air box so that the oil sludge is discharged according to the preset path.
[0040] The groove 1 blocks the flow of oil in the front-to-back direction. The oil that flows into the groove 1 flows out through the oil leakage hole 3 at the end of the groove 1, thus preventing oil leakage from contaminating the functional modules inside the air box.
[0041] Along the length of the groove 1, the bottom surface of the groove 1 includes a first inclined surface and a second inclined surface connected in sequence. The higher end of the first inclined surface is connected to the higher end of the second inclined surface. An oil leakage hole 3 is provided at the lower end of the first inclined surface. An oil leakage hole 3 is provided at the lower end of the second inclined surface.
[0042] The first and second inclined surfaces can be symmetrically arranged, that is, the groove 1 adopts a continuous inclined surface design with a high middle and low ends. In addition, oil drain holes 3 can be provided at both ends. By setting the first and second inclined surfaces, the distance of oil flowing to the oil drain holes 3 can be shortened, and the oil drain from the groove 1 can be accelerated.
[0043] Groove 1 is a through groove that runs through its two opposite ends.
[0044] like Figure 4 and Figure 5 As shown, in this embodiment, both ends of the groove 1 are open, and the open end of the groove 1 is directly connected to the inlet 13 on the side plate 12 of the bellows, forming a double oil leakage protection through the oil leakage hole 3 and the end connecting part. This structure causes oil to automatically gather to both sides, effectively blocking the front and back flow of oil on the surface of the cover plate, preventing oil from accumulating on the surface of the cover plate and flowing to the front side of the cover plate.
[0045] like Figure 2 As shown, in the front-back direction, the top surface of the part between the plate and the groove 1 is the third inclined surface 4, which gradually decreases from front to back.
[0046] A third slope 4, which is higher at the front and lower at the back, is formed between the front edge of the plate and the groove 1. The design of the third slope 4 can automatically guide the oil dripping onto the plate to the groove 1 area by gravity, so as to prevent the oil from accumulating at the front edge and seeping into the functional module cavity.
[0047] like Figure 2 As shown, the left and right sides of the third inclined surface 4 are respectively provided with upwardly folded edges 5, which form a barrier but do not close the two open ends of the groove 1. The three-dimensional folded edges 5 can prevent oil from flowing into the functional module cavity from the left and right sides of the cover plate, and can directly guide the oil flowing on both sides to the groove 1.
[0048] like Figure 6 As shown, the rear edge of the plate is provided with a multi-level flange 6 that continuously folds upwards. The multi-level flange 6 can increase the strength.
[0049] The multi-level flange 6 includes a first flange 7 extending upward from the rear edge of the plate, and a second flange 8 folded backward at the top of the first flange 7.
[0050] An elastic sealing strip 19 can be installed on the top surface of the second flange 8. The sealing strip 19 abuts against the bottom of the rear plate of the table frame 14 to prevent oil stains seeping between the machine head 18 and the table frame 14 from flowing into the main body surface of the front air box cover 17.
[0051] The rear edge of the second flange 8 is provided with a downward-folded third flange 9, and the bottom end of the third flange 9 is provided with a rearward-folded fourth flange 10, which slopes downward from front to back. The fourth flange 10 is designed to be higher at the front and lower at the back, so that oil can flow along the slope to a preset position in the air box.
[0052] The rear edge of the fourth flange 10 is also provided with a downward-folding fifth flange 11, which serves as a reinforcement and effectively supports the sealing between the first flange 7 and the table frame 14.
[0053] like Figure 1 As shown, a wire harness clip assembly is provided on the board body. The wire harness clip assembly includes multiple clips 2 arranged in the front-back direction. At least one clip 2 is located on the front side of the groove 1 and at least one clip 2 is located on the rear side of the groove 1. The opening direction of the clip 2 is upward. The wire harness of the component can be fixed on the clip 2 in the front-back direction to prevent the wire harness from contacting the oil stains in the groove 1, and at the same time facilitate the installation and maintenance of the wire harness.
[0054] The groove 1, the third inclined surface 4, and the multi-level flange 6 in the bellows cover plate 17 can be integrally formed.
[0055] like Figures 3-5 As shown, the integrated stove provided by this utility model includes the aforementioned air box cover 17; the integrated stove also includes a side plate 12, which is located at the end of the groove 1, and the side plate 12 is provided with an inlet 13 facing the opening at the end of the groove 1.
[0056] The integrated stove has side panels 12 on both the left and right sides. Taking the left side as an example, the left edge of the panel contacts the surface of the side panel 12. The left end of the groove 1 is open, directly opposite the side panel 12. An inlet 13 is provided on the side panel 12. Oil flowing along the groove 1 towards the end can enter the oil drain hole 3. When the oil drain hole 3 is blocked, the oil can also pass through the oil drain hole 3 and enter the inlet 13 of the side panel 12, thus flowing to the preset position. The oil drain hole 3 and the inlet 13 on the side panel 12 form a double oil leakage protection, preventing oil in the groove 1 from overflowing to other positions.
[0057] like Figure 6 As shown, another integrated stove provided by this utility model includes the aforementioned air box cover 17; specifically, the integrated stove also includes a countertop frame 14 and a motor head 18, with the countertop frame 14 located above the air box cover. The countertop frame 14 includes a base plate 15 and a back plate 16 connected to the base plate 15, and the motor head 18 is located on the rear side of the back plate 16. The base plate 15 is supported above the second flange 8, and a sealing strip 19 is provided between the two.
[0058] The back panel 16 is located on the rear side of the rear edge of the second flange 8.
[0059] The rear edge of the second flange 8 is located on the front side of the back panel 16 of the table frame 14, so that the oil stains that seep between the table frame 14 and the machine head 18 will not flow to the front sealing strip 19.
[0060] The oil stains that seep between the table frame 14 and the head 18 will fall onto the fourth flange 10, and then continue to flow backward under the guidance of the fourth flange 10, flowing into the preset position in the air box to avoid contaminating the components.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
