[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0032] See also Figures 1 to 5 The utility model discloses an oil receiving structure, which is used for a range hood, and includes a back plate assembly 1 and an oil guide member 2. The back plate assembly 1 includes a back plate 11 and a front plate 12, and an oil guide cavity 13 is provided between the back plate 11 and the front plate 12; the oil guide member 2 has an oil guide groove 21 and a connecting portion 22, and the connecting portion 22 is provided on the rear side wall of the oil guide member 2, and the connecting portion 22 is used to connect the back plate assembly 1, and an oil guide hole 211 is provided on the rear side wall of the oil guide groove 21, and the oil guide hole 211 is communicated with the oil guide cavity 13.

[0033] When the oil receiving structure of the present invention is applied to the range hood, the oil guide part 2 is located below the main oil cup of the range hood, and the downward projection of the lowest point of the bottom plate of the main oil cup falls into the oil guide groove 21 of the oil guide part 2. When the oil accumulated on the outer wall of the main oil cup of the range hood drips downward, it is received by the oil guide groove 21, thereby preventing the oil accumulated on the outer wall of the main oil cup from dripping onto the stove.

[0034] In the oil receiving structure of the present invention, an oil guide cavity 13 is provided on the back plate assembly 1. After a certain amount of oil accumulates in the oil guide groove 21, the oil in the oil guide groove 21 can be introduced into the oil guide cavity 13 through the oil guide hole 211. The oil guide cavity 13 can collect the oil in the oil guide groove 21 to prevent the oil in the oil guide groove 21 from overflowing.

[0035] See also Figures 2 to 5The oil receiving structure of the present invention, the back panel assembly 1 also includes an oil separator 14. The back panel 11 and the oil separator 14 form an oil guide cavity 13. The oil separator 14 is provided with a back panel oil outlet hole 141 for guiding the oil in the oil guide cavity 13 out of the oil guide cavity 13. The oil separator 14 is arranged between the back panel 11 and the front panel 12, so that the oil separator 14 and the back panel 11 form an oil guide cavity 13. After the oil in the oil guide groove 21 enters the oil guide cavity 13, it is blocked by the oil separator 14 and will not come into contact with the front panel 12, which can prevent the oil from overflowing from the gap between the back panel 11 and the front panel 12. When the front panel 12 is set as a decorative panel, a light board can be set on the inner side of the front panel 12, so that the oil will not contaminate the inner side of the front panel 12, thereby avoiding contamination of the light board. When the light board lights up the front panel 12, the effect presented by the front panel 12 can be guaranteed.

[0036] In the oil receiving structure of the present invention, the oil separator 14 is provided with a back plate oil outlet hole 141 for conducting the oil in the oil guide cavity 13 out of the oil guide cavity 13. The oil entering the oil guide cavity 13 through the oil guide groove 21 will be discharged through the oil guide cavity 13, forming an oil discharge path.

[0037] The oil receiving structure of the present invention has an oil separator 14 with a connecting plate at the lower end thereof which is tilted backward from top to bottom. The rear edge of the connecting plate is connected to the back plate 11. The connecting plate forms the cavity bottom plate of the oil guide cavity 13. The back plate oil outlet hole 141 is provided on the connecting plate. When the oil in the oil guide cavity 13 is discharged through the back plate oil outlet hole 141, the oil flows along the inner wall of the back plate 11.

[0038] See also Figure 3 The oil receiving structure of the present invention comprises an oil guide cavity 13 having a cavity top plate 131. The front edge of the cavity top plate 131 is connected to the upper edge of the oil separator 14, the rear edge of the cavity top plate 131 is connected to the upper edge of the back plate 11, and the connecting portion 22 is connected to the cavity top plate 131. The oil separator 14 is provided with a connecting hole 142 that communicates with the oil guide cavity 13. The oil guide hole 211 communicates with the oil guide cavity 13 through the connecting hole 142. The oil guide member 2 is connected to the back plate assembly 1, and the connecting portion 22 of the oil guide member 2 is connected to the cavity top plate 131 of the oil guide cavity 13. When the oil receiving structure is applied to a range hood, the connecting portion 22 is located between the cavity top plate 131 and the corresponding connecting surface of the range hood, thereby enhancing the strength of the surface of the back plate assembly 1 used for connection to the range hood.

[0039] The oil receiving structure of the present invention is configured with a cavity top plate 131 on the top of the oil guide cavity 13 and a connecting hole 142 on the oil separator 14, so that the oil in the oil guide groove 21 enters the oil guide cavity 13 through the connecting hole 142, without affecting the discharge of the oil in the oil guide groove 21 into the oil guide cavity 13.

[0040] See also Figure 1 and Figure 3 ,exist Figure 1 and Figure 3In the embodiment shown, the connecting portion 22 is formed by extending backward from the upper edge of the rear side wall of the oil guide groove 21, so that after the connecting portion 22 is connected to the cavity top plate 131 of the oil guide cavity 13, the bottom height of the oil guide groove 21 is lower than the height of the upper edges of the back plate 11 and the oil separator 14, and the bottom of the oil guide groove 21 is located below the upper edge of the oil separator 14. In order to reduce the thickness of the back plate assembly 1, the height of the front plate 12 is lower than the height of the upper edge of the oil separator 14. After the oil guide part 2 is connected to the back plate assembly 1, the upper edge of the front plate 12 is located below the oil guide part 2. The optimal solution is that the upper edge of the front plate 12 abuts against the lower surface of the bottom of the oil guide groove 21. From the user's side, there is no gap between the front plate 12 and the oil guide part 2, which makes the appearance of the oil receiving structure more beautiful.

[0041] See also Figures 4 to 6 In the oil receiving structure of the present invention, the oil guide member 2 is further provided with a connecting block 23. The connecting block 23 is located on the rear side of the rear side wall of the oil guide groove 21. The connecting block 23 is provided with an oil guide channel 231. The oil guide channel 231 communicates with the oil guide groove 21 through the oil guide hole 211. The connecting block 23 is adapted to and connected to the communication hole 142. If, after the oil guide member 2 is assembled to the back panel assembly 1, the oil guide hole 211 is merely aligned with the communication hole 142 on the oil separator 14, the oil separator 14 needs to be in close contact with the rear side of the rear side wall of the oil guide groove 21. When the oil in the oil guide groove 21 flows out through the oil guide hole 211, some oil will flow out from the gap between the oil separator 14 and the rear side of the rear side wall of the oil guide groove 21. The flowing oil will adhere to the rear side of the front panel 12. If a light board is installed on the rear side of the front panel 12, it will contaminate the light board and affect the display performance of the light board. The oil receiving structure of the present invention is directly provided with a connecting block 23 extending into the oil guide cavity 13 through the connecting hole 142. The oil in the oil guide groove 21 flows out through the oil guide hole 211 and enters the oil guide channel 231 on the connecting block 23, and is directly introduced into the oil guide cavity 13 through the oil guide channel 231. The oil outlet of the oil guide channel 231 is located in the oil guide cavity 13. No oil will appear between the oil separator 14 and the front plate 12, which can ensure that no oil enters the space between the oil separator 14 and the front plate 12.

[0042] See also Figure 5 and Figure 6 In the oil receiving structure of the present invention, a guide plate 232 extends downward from the lower edge of the outlet of the oil guide channel 231. After the oil in the oil guide groove 21 flows out through the oil guide hole 211 and enters the oil guide channel 231, it flows along the oil guide channel 231 to the oil outlet of the oil guide channel 231, and then is drained downward through the guide plate 232 and flows into the oil guide cavity 13.

[0043] The oil receiving structure of the present invention is provided with a downwardly extending guide plate 232 at the lower edge of the outlet of the oil guide channel 231, which guides the oil in the oil guide channel 231 into the oil guide cavity 13 from the bottom of the connecting block 23, so that the oil does not adhere to the portion where the oil separator 14 and the connecting block 23 are aligned, thereby preventing the oil from leaking through the gap between the connecting hole 142 and the connecting block 23.

[0044] See also Figure 3 and Figure 4 In the oil receiving structure of the present invention, the front sidewall of the oil guide groove 21 has an arcuate section 212 extending downward to below the bottom plate of the oil guide groove 21. After the oil guide member 2 is connected to the back plate assembly 1, the lower edge of the arcuate section 212 abuts the front side surface of the front plate 12. The side of the arcuate section 212 facing the user is an arcuate surface that is concave away from the user. This arcuate surface of the arcuate section 212 is concave away from the user relative to the other parts of the front sidewall of the oil guide groove 21. The portion of the front sidewall of the oil guide groove 21 provided with the arcuate section 212 reduces the thickness at the corresponding location, saving material and improving visual appearance.

[0045] See also Figure 3 and Figure 4 In the oil receiving structure of the present invention, the portion of the oil guide groove 21 located above the arcuate segment 212 is a vertical segment 213. The lower edge of the vertical segment 213 connects to the upper edge of the arcuate segment 212, and the height of the lower edge of the vertical segment 213 is greater than the height of the lower edge of the rear sidewall of the oil guide groove 21. The rear sidewall of the arcuate segment 212 protrudes into the oil guide groove 21, and the vertical segment 213 is arranged vertically. The corresponding portion of the vertical segment acts as a closing function to prevent oil from overflowing from the oil guide groove 21.

[0046] See also Figure 1 and Figure 2 In the oil receiving structure of the present invention, after the oil guide member 2 is connected to the back plate assembly 1, the upper edge of the front plate 12 abuts against the bottom plate of the oil guide groove 21. After the oil guide member 2 is connected to the back plate assembly 1, the connecting portion 22 of the oil guide member 2 is connected to the cavity top plate 131 of the oil guide cavity 13, the lower surface of the bottom of the oil guide groove 21 abuts against the upper edge of the front plate 12, and the arc segment 212 extends downward to the portion below the bottom of the oil guide groove 21 and extends downward to the front side of the front plate 12, ensuring that at least the lower edge of the arc segment 212 abuts against the front side surface of the front plate 12. This ensures that there is no gap between the arc segment 212 and the front plate 12, making it difficult for dirt to accumulate and facilitating cleaning of the front plate 12.

[0047] See also Figure 7 and Figure 8The present invention also discloses a range hood, which adopts the above-mentioned oil receiving structure, including a range hood body 3, the oil receiving structure is connected to the bottom of the range hood body 3, the range hood body 3 has a smoke collecting chamber, an air intake 31 connected to the smoke collecting chamber, and an oil outlet 32 connected to the smoke collecting chamber, and also includes a main oil cup 4, the main oil cup 4 is connected to the range hood body 3, the opening of the accommodating cavity of the main oil cup 4 faces the oil outlet 32, and the lowest projection of the main oil cup 4 falls into the oil guide groove 21. The range hood of the present invention is started when the user is cooking, and the smoke exhaust fan in the smoke collecting chamber of the range hood main body 3 is started, and the oil smoke generated by the user's cooking enters the air collecting chamber through the air intake 31. In the process of the oil smoke entering the smoke collecting chamber through the air intake 31, the oil liquid formed by the mixture of oil and water in the oil smoke that contacts the main oil cup 4 will adhere to the outer surface of the oil cup 4. When it adheres to a certain amount and can form oil droplets dripping downward, the oil droplets drip from the lowest point of the main oil cup 4 and are received by the oil guide groove 21. The oil liquid gathers in the oil guide groove 21 and flows out from the oil guide hole 211. The oil flowing out through the oil guide hole 211 enters the oil guide channel 231 on the connecting block 23, and then is discharged into the oil guide chamber 13 through the oil guide channel 231. During the long-term operation of the range hood, the oil liquid formed by the mixture of oil and water in the oil smoke entering the smoke collecting chamber will adhere to the inner wall surface of the smoke collecting chamber and the volute of the smoke exhaust fan. When the smoke exhaust fan stops running, the oil liquid on the volute of the smoke exhaust fan is discharged into the bottom of the smoke collecting chamber. After the oil liquid on the inner wall surface of the smoke collecting chamber accumulates to a certain amount, it will also drip to the bottom of the smoke collecting chamber, and then be discharged through the oil outlet hole 32 connected to the smoke collecting chamber and be received by the main oil cup 4.

[0048] In the range hood of the present invention, the oil guide groove 21 can receive the oil dripping from the main oil cup 4, preventing the oil from the main oil cup 4 from dripping onto the user's stove, thereby improving the user experience.
