[0027] 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:

[0028] See also Figures 1 to 3The utility model discloses a range hood, which includes a range hood body 1, a main oil cup 2 and a secondary oil cup 3. The range hood body 1 has a smoke collecting chamber 11, a panel 12 facing the user side and an oil leakage hole 13 connected to the smoke collecting chamber 11; the main oil cup 2 is connected to the range hood body 1, and the opening of its accommodating chamber faces the oil leakage hole 13, for receiving oil dripping through the oil leakage hole 13; the secondary oil cup 3 is connected to the range hood body 1, for receiving oil dripping from the outer surface of the main oil cup 2 and the panel 12. When the range hood of the present invention is working, the oil smoke flows into the smoke collecting chamber 11 under the action of the smoke exhaust fan of the range hood, and the oil and water mixture in the oil smoke will adhere to the outer surface of the main oil cup 2. The oil smoke will also flow along the panel 12 when flowing into the smoke collecting chamber 11, and the oil and water mixture will adhere to the panel 12. When the oil and water mixture on the main oil cup 2 adheres to a certain amount, it will gather into oil droplets and drip into the auxiliary oil cup 3. When the oil and water mixture on the panel 12 adheres to a certain amount, it will also flow along the panel 12 and finally drip into the auxiliary oil cup 3. The existence of the auxiliary oil cup 3 can prevent the oil and water mixture gathered on the main oil cup 2 and the panel 12 from dripping down into the stove or pot.

[0029] The range hood of the present invention has a main body 1 with a top plate 14, an oil leakage hole 13 provided on the top plate 14, and a main oil cup 2 connected to the top plate 14. The exhaust fan of the range hood is located in the smoke collecting chamber 11, above the top plate 14. During operation of the range hood, after the oil smoke enters the smoke collecting chamber 11 and is discharged from the smoke collecting chamber 11 by the exhaust fan, the oil and water mixture in the oil smoke will be thrown onto the volute of the exhaust fan under the centrifugal force of the exhaust fan. After the exhaust fan stops running, the oil and water mixture in the volute of the exhaust fan will be discharged downward from the volute and enter the bottom of the smoke collecting chamber 11, and then enter the main oil cup 2 through the oil leakage hole 13. Since the oil leakage hole 13 and the main oil cup 2 are arranged on the top plate 14 of the range hood body 1, the oil liquid formed by the mixture of oil and water drips from the volute of the smoke exhaust fan, gathers at the bottom of the smoke collecting chamber 11, and then flows out directly through the oil leakage hole 13 and falls into the main oil cup 2. The flow path of the oil liquid formed by the mixture of oil and water when entering the main oil cup 2 from the smoke collecting chamber 11 can be shortened, and the oil liquid formed by the mixture of oil and water in the smoke collecting chamber 11 can be discharged in time.

[0030] See also Figures 1 to 3The range hood of the present invention is further provided with an air intake 15 on the top plate 14, which is connected to the smoke collection chamber 11. The oil leakage hole 13 is located behind the air intake 15. A range hood with an air intake 15 on the top plate 14 is a top-suction type range hood. The air intake 15 of a top-suction range hood is closer to the range hood's exhaust fan, allowing oil smoke that enters the smoke collection chamber 11 through the air intake 15 to be promptly discharged from the smoke collection chamber 11 by the exhaust fan. Furthermore, the oil leakage hole 13 is located behind the air intake 15. After the main oil cup 2 is attached to the top plate 14, it is also located behind the air intake 15. When the range hood's exhaust fan is operating, the main oil cup 2 will not interfere with the flow of oil smoke toward the air intake 15.

[0031] The range hood with the air intake 15 located on the top plate 14 is a top-suction type range hood. In the present invention, the air intake 15 is located on the rear side of the top plate 14 of the range hood body 1 and is narrow and long. When the exhaust fan operates at the same power, the narrow and long air intake creates a greater negative pressure, thereby enhancing the ability to extract oil smoke. As the oil smoke flows toward the air intake 15, it flows from bottom to top and then tilts backward, ultimately being drawn into the smoke collection chamber 11 through the air intake 15. When the oil smoke enters the smoke collecting chamber 11 through the air intake 15, a large amount of oil smoke gathers at the air intake 15. Most of the oil smoke enters the smoke collecting chamber 11 directly through the air intake 15. Part of the oil smoke will be impacted by the air flow at the air intake 15 and will pass through the air intake 15 and move backward along the top plate 14 and rush onto the main oil cup 2. When the amount of oil smoke is large, when the oil smoke rises to the air intake 15, some of the oil smoke will come into contact with the main oil cup 2. Therefore, after the range hood has been working for a long time, the outer wall of the main oil cup 2 will also gather a lot of oil liquid formed by a mixture of oil and water. These oil liquids will gather at the bottom of the main oil cup 2. When the weight of the gathered oil liquid can overcome the adhesion of the oil liquid to the main oil cup 2, it will drip from the bottom of the main oil cup 2 and then be received by the auxiliary oil cup 3, which can prevent the oil dripping from the main oil cup 2 from falling directly onto the stove body or pot, affecting the user experience.

[0032] In addition, when the exhaust fan of the range hood is running, when the oil smoke flows from top to bottom and tilted backward toward the air intake 15, part of the oil smoke will flow upward along the panel 12. During the flow of the oil smoke, the oil liquid formed by the mixture of oil and water in the oil smoke will also adhere to the panel 12. After gathering to a certain amount, it will flow along the panel 12 and then drip into the auxiliary oil cup 3 and be received by the auxiliary oil cup 3. This can prevent the oil dripping from the panel 12 from falling directly onto the stove body or pot, affecting the user experience.

[0033] See also Figures 1 to 3 In the range hood of this invention, the auxiliary oil cup 3 is connected to the bottom of the panel 12. The downward projection of the panel 12 falls into the accommodating cavity of the auxiliary oil cup 3. The oil collected on the panel 12 flows downward along the panel 12, finally gathering at the lower edge of the panel 12 and dripping into the auxiliary oil cup 3.

[0034] In some embodiments, the bottom surface of the main oil cup 2 is tilted downward from front to back, and the rear edge of the bottom surface of the main oil cup 2 abuts against the panel 12. The oil gathered on the outer wall of the main oil cup 2 flows along the bottom surface of the main oil cup 2, and finally gathers at the rear edge of the bottom surface of the main oil cup 2, and then flows to the panel 12 through the rear edge of the main oil cup 2, and finally flows downward along the panel 12, and together with other oil on the panel 12, drips from the lower edge of the panel 12 into the auxiliary oil cup 3 and is received by the auxiliary oil cup 3.

[0035] See also Figure 2 and Figure 3 The range hood body 1 of the present invention has a back plate 16. An oil guide chamber 17 is formed between the front plate 12 and the back plate 16. The bottom of the oil guide chamber 17 is provided with an oil guide hole, which communicates with the accommodating chamber of the secondary oil cup 3. Oil on the outer surface of the main oil cup 2 enters the oil guide chamber 17, flows along the oil guide chamber 17, and enters the secondary oil cup 3. After a certain amount of oil accumulates on the outer wall of the main oil cup 2, the oil drips from the bottom of the main oil cup 2 into the oil guide chamber 17 between the front plate 12 and the back plate 16. The oil then flows along the oil guide chamber 17, collects at the bottom of the oil guide chamber 17, and after a certain amount of oil has accumulated, it flows out through the oil guide hole at the bottom of the oil guide chamber 17 and enters the secondary oil cup 3. When the range hood is working, the oil gathers on the outer wall of the main oil cup 2 at a relatively fast speed. The oil dripping from the main oil cup 2 flows directly from the panel 12, which will affect the appearance and reduce user satisfaction. Therefore, an oil guide cavity 17 is provided between the panel 12 and the back panel 16, so that the oil gathered on the outer wall of the main oil cup 2 flows through the oil guide cavity 17. The user cannot see the flow path of the oil on the outer wall of the main oil cup 2, thereby improving the appearance of the range hood.

[0036] See also Figure 2 and Figure 3 In the range hood of the present invention, an oil guide member 18 is provided at the upper edge of the panel 12. This member 18 has an oil guide groove 181, the oil outlet of which communicates with the oil guide chamber 17. The bottom surface of the main oil cup 2 is tilted downward from front to back, with at least the projection of the rear edge of the bottom surface of the main oil cup 2 falling into the oil guide groove 181. When a certain amount of oil accumulates on the outer wall of the main oil cup 2, it drips through the bottom surface of the main oil cup 2 and is collected by the oil guide groove 181. After a certain amount of oil accumulates within the oil guide groove 181, it flows out of the oil guide groove 181 outlet and into the oil guide chamber 17. The oil guide member 18 is located at the upper edge of the panel 12 and below the main oil cup 2. It not only collects dripping oil from the main oil cup 2 but also blocks the gap between the panel 12 and the main oil cup 2, enhancing the appearance of the range hood body 1.

[0037] See also Figures 1 to 3In the range hood of the present invention, the front side wall of the oil guide groove 181 is an arcuate surface that protrudes into the oil guide groove 181, and the upper edge of the front side wall of the oil guide groove 181 extends forward. The upper edge of the front side wall of the oil guide groove 181 is lower than the lowest point of the main oil cup 2. The arcuate front side wall of the oil guide groove 181 improves the appearance of the range hood body 1. The upper edge of the front side wall of the oil guide groove 181 is lower than the lowest point of the main oil cup 2, which facilitates the removal and installation of the main oil cup 2. During removal and installation, the upper edge of the front side wall of the oil guide groove 181 will not interfere with the main oil cup 2.

[0038] See also Figures 1 to 3 In the range hood of the present invention, the lower edge of the curved surface of the front wall of the oil guide groove 181 extends downward to the front side of the panel 12. The upper edge of the panel 12 abuts the bottom surface of the oil guide groove 181, and the lower edge of the curved surface abuts the front side of the panel 12. After the panel 12 is properly installed on the range hood body 1, the upper edge of the panel 12 abuts the bottom surface of the oil guide groove 181, and the lower edge of the oil guide groove 181 is attached to the upper front end of the panel 12. This not only improves the appearance of the range hood body 1, but also prevents oil smoke from entering the rear side of the panel 12 through the gap between the oil guide member 18 and the upper edge of the panel 12. For some range hood models, the panel 12 needs to be installed with a lighting device. The lighting device can be installed on the upper edge of the panel 12 or on the back of the panel 12, so that the lower edge of the front wall of the oil guide groove 181 abuts the front side of the upper edge of the panel 12, to prevent oil smoke from entering the upper edge of the panel 12 or to prevent oil smoke from entering the back of the panel 12 through the gap between the upper edge of the panel 12 and the oil guide part 18, to avoid contaminating the lighting device.

[0039] See also Figure 2 and Figure 3The range hood of the present invention also includes an oil guide plate 19, which is arranged in the oil guide cavity 17. The upper edge of the oil guide plate 19 extends upward to the oil outlet of the oil guide member 18, and the lower edge of the oil guide plate 19 is connected to the inner wall surface of the back plate 16. An oil outlet hole is provided at the junction of the lower edge of the oil guide plate 19 and the back plate 16. The oil in the oil guide groove 181 flows downward along the oil guide plate 19, and flows through the oil outlet hole to the part of the inner wall surface of the back plate 16 located below the oil guide plate 19, and flows along the back plate 16 to the bottom of the oil guide cavity 17. After flowing out of the oil outlet of oil guide groove 181, the oil flows along oil guide plate 19 and is collected at the bottom of oil guide plate 19. It then flows out through the oil outlet hole where the lower edge of oil guide plate 19 meets back plate 16, flows along the portion of back plate 16 below oil guide plate 19, and finally is collected in oil guide cavity 17, entering auxiliary oil cup 3 through the oil guide hole at the bottom of oil guide cavity 17. In the present utility model, oil guide plate 19 is arranged to be tilted downward from front to back. After flowing out of oil guide groove 181, the oil flows downward along the tilted oil guide plate 19. Oil guide plate 19 guides the oil to back plate 16, preventing oil from dripping directly from oil guide plate 19 and generating noise, and also preventing oil from adhering to the inner side of panel 12.

[0040] See also Figure 2 In the range hood of the present invention, the top plate 14 is tilted downward from front to back, with the projection of the rear edge of the top plate 14 falling into the main oil cup 2. When the range hood is in operation, negative pressure is formed at the air intake 15, causing oil smoke to flow toward the air intake. A large amount of oil smoke is drawn into the air intake 15, and a mixture of oil and water in the oil smoke adheres to the top plate 14. This causes the top plate 14 to tilt downward from front to back, with the rear edge of the top plate 14 projecting downward into the main oil cup 2. This allows the oil accumulated on the top plate 14 to flow along the top plate 14 and drip from the rear edge of the top plate 14 into the main oil cup 2, preventing the oil on the top plate 14 from entering the stove body or the user's pots and pans.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
