[0035] Example 1

[0036] like Figures 1-9 As shown, this utility model embodiment provides an oil guide plate installation structure applied to a range hood. The range hood includes a back plate 1 and an oil guide plate 2. The oil guide plate installation structure includes a hook-and-plug structure constructed between the oil guide plate 2 and the back plate 1. The hook-and-plug structure enables the oil guide plate 2 to be fixed on the back plate 1.

[0037] In this embodiment, the oil guide plate mounting structure is applied to a range hood. The range hood includes a back panel 1 and an oil guide plate 2. The oil guide plate mounting structure in this embodiment includes a hook-and-plug structure constructed between the oil guide plate 2 and the back panel 1. The hook-and-plug structure allows the oil guide plate 2 to be fixed to the back panel 1, avoiding the need for screws to fix the oil guide plate 2 to the back panel 1. This prevents screws from scratching the internal wiring of the range hood and causing damage to the wiring, thus improving safety. It also avoids the problem of workers needing to change the direction of the fan to tighten the oil guide plate screws, which would cause difficulties in production and assembly, thus improving production efficiency.

[0038] The oil guide plate 2 is installed below the volute and its function is to guide the oil flowing down from the volute into the oil cup, so as to keep the entire machine body clean.

[0039] In some embodiments, the mounting structure includes a first mounting portion 11 constructed on the back plate 1 and extending upward, and a mounting portion 21 constructed on the oil guide plate 2, wherein the mounting portion 21 is inserted between the first mounting portion 11 and the back plate 1.

[0040] The mounting structure of this embodiment includes a first mounting portion 11 constructed on the back plate 1 and extending upward, and a mounting portion 21 constructed on the oil guide tray 2. In this embodiment, the mounting portion 21 is inserted between the first mounting portion 11 and the back plate 1, allowing the oil guide tray 2 to be mounted on the back plate 1. This avoids the need for screws to fix the oil guide tray 2 to the back plate 1, preventing screws from scratching the internal wiring of the range hood and causing damage, thus improving safety. It also avoids the difficulty in production and assembly caused by workers needing to change the direction of the fan when screwing in the oil guide tray, thus improving production efficiency.

[0041] In some embodiments, the back plate 1 has two spaced vertical cutting lines 12 and a horizontal cutting line 13 connected to the top of the two vertical cutting lines 12, such that the portion between the two vertical cutting lines 12 and the horizontal cutting line 13 forms the first hanging part 11.

[0042] In this embodiment, two vertical cutting lines 12 spaced apart and a horizontal cutting line 13 connected to the top of the two vertical cutting lines 12 are provided on the back plate 1. The first hanging part 11 is formed by the part between the two vertical cutting lines 12 and the horizontal cutting line 13. Specifically, the first hanging part 11 is formed by stamping. In this embodiment, the first hanging part 11 is formed by stamping the part between the two vertical cutting lines 12 and the horizontal cutting line 13, which saves materials and reduces production costs.

[0043] In some embodiments, the first mounting portion 11 includes a first extension 111 extending toward the oil guide plate 2 and a second extension 112 connected to the end of the first extension 111 away from the back plate 1 and extending upward, the insertion portion 21 being located above the first extension 111 and sandwiched between the second extension 112 and the back plate 1.

[0044] The first mounting part 11 in this embodiment includes a first extension section 111 extending toward the oil guide tray 2 and a second extension section 112 connected to the end of the first extension section 111 away from the back plate 1 and extending upward. By placing the insertion part 21 above the first extension section 111 and clamping the insertion part 21 between the second extension section 112 and the back plate 1, the oil guide tray 2 is mounted on the back plate 1. This avoids the problem of screws damaging the wiring inside the range hood, thus improving safety. It also avoids the difficulty in production and assembly caused by workers needing to change the direction of the fan to screw in the oil guide tray, thus improving production efficiency.

[0045] In some embodiments, the insertion part 21 is parallel to the back plate 1, and the insertion part 21 is configured with a limiting groove 211 extending from the side away from the back plate 1 to the side facing the back plate 1, and the first hanging part 11 is located in the limiting groove 211.

[0046] In this embodiment, the insertion part 21 is parallel to the back plate 1. The insertion part 21 is constructed with a limiting groove 211 extending from the side away from the back plate 1 to the side facing the back plate 1. By setting the first hanging part 11 in the limiting groove 211, the oil guide plate 2 is prevented from moving along the width of the limiting groove 211. The width of the first hanging part 11 is equal to the width of the limiting groove 211.

[0047] In some embodiments, the limiting groove 211 extends vertically downward to the bottom of the insert portion 21, which facilitates the installation of the oil guide plate 2 and improves production efficiency.

[0048] In some embodiments, the oil guide plate mounting structure further includes a limiting member 3 and an insertion hole 14 opened on the back plate 1. The limiting member 3 is inserted into the insertion hole 14 and abuts against the top of the insertion part 21.

[0049] The oil guide plate mounting structure of this embodiment also includes a limiting member 3 and an insertion hole 14 opened on the back plate 1. The limiting member 3 is inserted into the insertion hole 14, and the limiting member 3 abuts against the top of the insertion part 21 to prevent the oil guide plate 2 from moving upward, causing the insertion part 21 of the oil guide plate 2 to detach from the first hanging part 11.

[0050] In some embodiments, the limiting member 3 includes a connecting portion 31 and conical cylinders 32 located at both ends of the connecting portion 31. The outer diameter of the conical cylinder 32 facing the connecting portion 31 is larger than the inner diameter of the insertion hole 14, and the outer diameter of the conical cylinder 32 away from the connecting portion 31 is smaller than the inner diameter of the insertion hole 14. The connecting portion 31 passes through the insertion hole 14, and the two conical cylinders 32 are located on both sides of the back plate 1. The conical cylinder 32 located on the side of the back plate 1 facing the oil guide plate 2 abuts against the top of the insertion portion 21.

[0051] The limiting member 3 in this embodiment includes a connecting part 31 and conical cylinders 32 located at both ends of the connecting part 31. The outer diameter of the end of the conical cylinder 32 facing the connecting part 31 is larger than the inner diameter of the insertion hole 14, and the outer diameter of the end of the conical cylinder 32 away from the connecting part 31 is smaller than the inner diameter of the insertion hole 14. By inserting the connecting part 31 into the insertion hole 14 and the two conical cylinders 32 located on both sides of the back plate 1, the conical cylinder 32 located on the side of the back plate 1 facing the oil guide plate 2 abuts against the top of the insertion part 21, preventing the oil guide plate 2 from moving upward and causing the insertion part 21 of the oil guide plate 2 to detach from the first hanging part 11.

[0052] In some embodiments, the limiting member 3 is made of an elastic material, such as rubber or silicone. The use of an elastic material makes it easier to insert the limiting member 3 into the insertion hole 14.

[0053] In some embodiments, the conical cylinder 32 located on the side of the back plate 1 facing the oil guide plate 2 is provided with a tangential surface 321, which abuts against the top of the insert portion 21.

[0054] In this embodiment, the tangential surface 321 of the conical cylinder 32 located on the side of the back plate 1 facing the oil guide plate 2 abuts against the top of the insertion part 21, preventing the oil guide plate 2 from moving upward and causing the insertion part 21 of the oil guide plate 2 to detach from the first hanging part 11.

[0055] In some embodiments, the oil guide plate 2 has insertion parts 21 on both sides, and the back plate 1 has the first hanging part 11 at the corresponding positions of the two insertion parts 21, thereby improving the stability of the oil guide plate 2 installation.
