[0021] like Figures 1-3 As shown, this embodiment of the utility model provides an oil and water circuit structure for a range hood, including a fan box 1 and a smoke collection hood 2 arranged sequentially from top to bottom. For clarity, the following definitions are provided. Figure 1 The top is "up," the bottom is "down," the right is "front," and the left is "back." The air box 1 contains an air handling unit 3, and the bottom of the air box 1 has an air inlet 11. The air handling unit 3 is located to the side of the air inlet 11. The air handling unit 3 is connected to the side wall of the air box 1 via an oil guide bracket 4, and the oil guide bracket 4 is located above the air inlet 11. The bottom end of the oil guide bracket 4 has an oil guide bevel 41, and the bottom end (lower end) of the oil guide bevel 41 abuts against the side wall of the air box 1 and / or the side wall of the air handling unit 3. For example... Figure 5 , Figure 6 , Figure 8 As shown, the top of the smoke hood 2 is provided with an air outlet 21 that is connected to the air inlet 11. Below the air outlet 21 is a U-shaped oil receiving tray 5, the two ends of which are located at the rear end of the oil receiving tray 5 and abut against the back plate 22 of the smoke hood 2.

[0022] The oil and water circuit structure of the range hood provided in this embodiment guides the oil and water inside the range hood as follows: the oil and water on the oil guide bracket 4 are guided by the oil guide inclined edge 41 to the side wall of the air box 1 and / or the side wall of the air cabinet 3; the oil and water on the side wall of the air box 1 flow downwards to the bottom plate of the air box 1; the oil and water on the air cabinet 3 flow downwards along the side wall of the air cabinet 3 to the bottom plate of the air box 1; the oil and water on the bottom plate of the air box 1 flow downwards along the edge of the air inlet 11, first collecting on the oil receiving tray 5, then flowing to the rear end of the oil receiving tray 5, and flowing downwards along the back plate 22 of the smoke collection hood 2, finally flowing to the bottom of the smoke collection hood 2 and collecting there. Since the oil receiving tray 5 is U-shaped, the space in its middle allows oil fumes to flow from the smoke collection hood 2 to the air box 1, without affecting the performance of the range hood. Because the oil and water circuits of this range hood have a reasonable and clear path, the problem of oil and water leakage can be eliminated.

[0023] Specifically, the shape of the oil guide bevel 41 can be one of three types: The first type gradually rises along the direction from the side wall of the air box 1 to the air handling unit 3, in which case the oil and water on the oil guide bracket 4 are guided to the side wall of the air box 1; the second type gradually decreases along the direction from the side wall of the air box 1 to the air handling unit 3, in which case the oil and water on the oil guide bracket 4 are guided to the side wall of the air handling unit 3; the third type gradually rises to a middle position along the direction from the side wall of the air box 1 to the air handling unit 3, and then gradually decreases, in which case the oil and water on the oil guide bracket 4 are guided to both the side wall of the air box 1 and the side wall of the air handling unit 3. For example... Figure 2 As shown, this embodiment illustrates the third structural form. Furthermore, the oil guide bracket 4 has connecting plates 42 at both ends for connecting the side wall of the air box 1 and the side wall of the air handling unit 3.

[0024] like Figure 1 , Figure 3 As shown, in one embodiment of this utility model, the air inlet 11 is located at the rear end of the air box 1 near the rear plate 12 of the air box 1. The rear plate 12 of the air box 1 corresponds to the back plate 22 of the smoke hood 2, forming a smooth vertical plane. One end of the oil guide bracket 4 is connected to the side wall of the air handling unit 3, and the other end is connected to the rear plate 12 of the air box 1. Oil and water on the rear plate 12 of the air box 1 can flow downward along the rear plate 12 of the air box 1, pass through the air inlet 11 and the air outlet 21, and continue to flow downward along the back plate 22 of the smoke hood 2.

[0025] like Figure 1 , Figure 5 , Figure 6As shown, in one embodiment of this utility model, the bottom of the smoke collection hood 2 is provided with an oil cup 6 that communicates with the interior of the smoke collection hood 2, so that the oil and water collected at the bottom of the smoke collection hood 2 can flow into the oil cup 6. Furthermore, the oil cup 6 is detachably connected to the bottom of the smoke collection hood 2 to facilitate the removal of oil and water from the oil cup 6.

[0026] To divert oil droplets from the side wall of the air handling unit 3 and prevent them from falling directly into the air inlet 11, such as... Figure 1 , Figure 3 As shown, in one embodiment of this utility model, the bottom side of the blower 3 is provided with an oil guide plate 7, which is located below the oil guide bracket 4. Figure 4 As shown, the oil guide plate 7 includes a vertical plate 71, and a downwardly extending inclined plate 72 at the bottom of the vertical plate 71. The inclined plate 72 is located between the bottom of the blower 3 and the bottom plate of the air box 1. The vertical plate 71 is fixedly connected to the side of the blower 3. Preferably, the two are detachably connected to facilitate the replacement of the oil guide plate 7. Oil and water flowing to the side of the blower 3 through the inclined oil guide edge 41, as well as oil and water directly condensed on the side wall of the blower 3, flow downward under the action of gravity, and finally flow along the vertical plate 71 and the inclined plate 72 to the bottom of the blower 3, dripping onto the bottom plate of the air box 1, without dripping directly from the air inlet 11 onto the stove. Furthermore, the oil guide plate 7 is provided with a molding process to enhance its strength and prevent easy deformation during the production process. At the same time, after installation, it can avoid resonance and abnormal noise caused by insufficient strength.

[0027] like Figure 1 , Figure 3 , Figure 4 As shown, in one embodiment of this utility model, the bottom of the blower 3 is provided with an oil drain port 31, which allows oil and water on the blades or worm gear inside the blower 3 to leak onto the bottom plate of the blower box 1, and then flow into the oil receiving tray 5 and down along the back plate 22 of the smoke collection hood 2. Preferably, the height of the oil receiving tray 5 gradually decreases from front to back, facilitating the flow of oil and water onto the back plate 22 of the smoke collection hood 2 under the action of gravity. Figure 1 , Figure 5 , Figure 6 , Figure 8 As shown, to improve the structural strength of the oil receiving pan 5, reinforcing ribs 51 are provided inside the oil receiving pan 5. Furthermore, multiple reinforcing ribs 51 form a grid. In addition, to prevent oil and water from flowing out from the side of the oil receiving pan 5, the inner and / or outer sides of the oil receiving pan 5 are provided with upwardly protruding oil-blocking edges 52.

[0028] To prevent oil and water from flowing disorderly on the front side of the back plate 22 of the smoke hood 2, such as Figure 9As shown, in one embodiment of the present invention, the front side of the back plate 22 is provided with a vertical oil guide groove 23, which corresponds to the end of the oil receiving tray 5, so that the oil and water flowing down from the end of the oil receiving tray 5 can flow downward along the oil guide groove 23, which can prevent the oil path from passing through the air inlet channel and causing oil droplets or water droplets to splash.

[0029] like Figure 1 , Figure 6 , Figure 10 , Figure 11 As shown, in one embodiment of this utility model, the front side of the smoke hood 2 is provided with an air inlet plate 24, and the air inlet plate 24 is provided with air inlet holes 25. Figure 7 As shown, the bottom front side of the smoke hood 2 is provided with an upwardly extending baffle 26. The bottom end of the air inlet plate 24 is located inside the baffle 26, forming a gap between it and the baffle 26. Preferably, this gap is 3mm. A gap is also formed between the bottom end of the air inlet plate 24 and the bottom plate of the smoke hood 2. Oil and water on the front (outer) side of the air inlet plate 24 can flow downwards and enter the interior of the smoke hood 2 through this gap, without falling outside the smoke hood 2. At the same time, oil and water on the rear (inner) side of the air inlet plate 24 can flow downwards to the bottom of the smoke hood 2. Preferably, as shown... Figure 10 , Figure 11 As shown, the edge of the air inlet 25 has an inwardly protruding flange 27, which can guide oil and water to the side of the air inlet 25, preventing dripping from the air inlet 25 and preventing oil and water from seeping out from the inner side of the air inlet plate 24. Preferably, the cross-section of the flange 27 is arc-shaped, which can prevent oil droplets from the straight edge from dripping directly to the outside.

[0030] This utility model also provides a range hood, including the above-mentioned range hood oil and water circuit structure.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
