[0029] See Figures 1-3 A range hood includes a smoke collection hood 1 and an oil cup 2. The oil cup is disposed on the smoke collection hood 1 and is used to collect the oil flowing down from inside the smoke collection hood 1.

[0030] See Figures 2-6 The range hood also includes an integrally molded oil cup holder 3 for accommodating the oil cup 2. The oil cup holder 3 is located inside the smoke hood 1, and the front side of the oil cup holder 3 is open in shape to fit the oil cup 2. The smoke hood 1 includes a front side plate 11, on which a mounting opening 111 in shape to fit the oil cup 2 is provided, and the mounting opening 111 is correspondingly arranged with the open end of the oil cup holder 3.

[0031] The front panel 11 includes a front panel body 121, and a mounting opening 111 is formed on the front panel body 121. A first bend 112 extending rearward and a second bend 113 bending upward from the first bend 112 are formed on the upper part of the front panel body 121 corresponding to the mounting opening 111. A third bend 114 extending rearward and a fourth bend 115 bending downward from the third bend 114 are formed on the lower part of the front panel 11 corresponding to the mounting opening 111. A fifth bend 116 extending rearward and a sixth bend 117 bending leftward from the fifth bend 116 are formed on the left part of the front panel 11 corresponding to the mounting opening 111. A seventh bend 118 extending rearward and an eighth bend 119 bending rightward from the seventh bend 118 are formed on the right part of the front panel 11 corresponding to the mounting opening 111.

[0032] A first snap-fit ​​hole 1151 is provided on the fourth bend 115, a second snap-fit ​​hole 1171 is provided on the sixth bend 117, and a third snap-fit ​​hole 1191 is provided on the eighth bend 119. A first snap 31 capable of snapping onto the top of the second bend 113 is formed on the upper front side of the oil cup holder 3, a second snap 32 engaging with the first snap-fit ​​hole 1151 is formed on the lower front side of the oil cup holder 3, a third snap 33 engaging with the second snap-fit ​​hole 1171 is formed on the upper front side of the oil cup holder 3, a fourth snap 34 engaging with the third snap-fit ​​hole 1191 is formed on the upper front side of the oil cup holder 3, the left front side of the oil cup holder 3, and the right front side of the oil cup holder 3. The first bend 112, the third bend 114, the fifth bend 116, and the seventh bend 118 constitute an annular folded edge structure.

[0033] To prevent the oil cup holder 3 from sliding up and down relative to the front side plate 11, the fourth bend 115, the sixth bend 117, and the eighth bend 119 are each provided with a first screw hole 120. A second screw hole 37 is provided on the front side of the oil cup holder 3 corresponding to the first screw hole 120. The first screw hole 120 and the second screw hole 37 are connected by screws. A screw connection can also be achieved by providing corresponding screw holes on the second bend 113 and the front side plate 3. The distance between the second bend 113, the fourth bend 115, the sixth bend 117, and the eighth bend 119 and the front side plate body 121 is greater than the length of the screw shank, ensuring that the screw will not touch the front side plate body 121 when fixed, thus preventing unsightly appearance defects such as protrusions.

[0034] During assembly, the oil cup holder 3 only needs to align its front clips with the corresponding snap holes on the front side plate 11 before sliding downwards. The upper part of the annular folded edge structure (first bent edge 112) of the front side plate 11 ensures that after the oil cup holder 3 is installed, there is a relatively small gap between the lower inner end face of the first clip 31 on the upper part of the oil cup holder 3 and the first bent edge 112, thus guaranteeing the initial positioning of the screw holes. Finally, screws are used to connect the oil cup holder 3 to the front side plate 11 to constrain the upward and downward sliding movement of the oil cup holder 3.

[0035] See Figure 3 The projection of the inner contour of the annular folded edge structure onto the oil cup 2 in the placement direction (i.e., the front-to-back direction) is not less than the projection of the opening of the oil cup holder 3 onto the placement direction of the oil cup 2. Here, "not less than" means that the projection of the oil cup holder 3 does not exceed the projected contour of the annular folded edge structure. This ensures that when observing the entire unit from the front after mounting, no visible seam between the front side panel 11 and the oil cup holder 3 can be observed.

[0036] See Figures 2-3 The inner side of the smoke hood 1 is provided with an oil storage component 4 that can collect the oil inside the smoke hood 1. The bottom of the oil storage component 4 is provided with an oil drain port 41, and the top of the oil cup seat 3 is provided with a clearance port 35 that allows the oil discharged from the oil drain port 41 to enter the oil cup 2.

[0037] See Figure 3 and Figure 6 The inner bottom of the oil cup holder 3 has a downward-facing recessed oil reservoir 36. The vertical projection of the oil outlet 41 lies within the vertical projection of the oil reservoir 36. The recessed shape of the oil reservoir 36 is arc-shaped.

[0038] The oil collection tank 36 is designed to collect and gather any oil spilled inside the oil cup holder 3 when the oil cup 2 is removed, as well as any oil dripping from the drain port 41. This prevents oil from leaking out due to lack of flow at the bottom of the oil cup holder 3. Furthermore, the concave shape of the oil collection tank 36 is arc-shaped, reducing hard-to-clean areas and facilitating subsequent cleaning of the collected oil.
