This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the embodiments of the present application.

[0052] In addition, it should be noted that in the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] The principles and features of the embodiments of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present application and are not used to limit the scope of the embodiments of the present application.

[0055] refer to Figure 1-Figure 6 The range hood provided in the embodiment of the present application includes a shell 1, a main box body 2, a fan 3 and a partition 4.

[0056] The housing 1 has a smoke inlet side, which is used to face the cooker. The smoke inlet side defines a smoke inlet port 12. The housing 1 may define a smoke collecting chamber 11, and the smoke collecting chamber 11 and the housing 1 are connected through the smoke inlet port 12.

[0057] The partition 4 is arranged on the top of the shell 1 , and the partition 4 and the shell 1 surround an oil fume outlet 13 .

[0058] The main box body 2 is arranged on the top of the housing 1, and the main box body 2 and the housing 1 are connected through the oil fume outlet 13. Since the space in the housing 1 is connected with the smoke inlet 12, the oil fume outlet 13 and the smoke inlet 12 are also connected.

[0059] The main housing 2 is provided with a smoke outlet 21. The smoke outlet 21 is used to communicate with a public flue or an outdoor environment through a smoke exhaust pipe.

[0060] The fan 3 is disposed in the main housing 2. The fan 3 has an air inlet 31 and an air outlet 32. The air inlet 31 is disposed near the oil fume outlet 13, and the air outlet 32 ​​is disposed near the smoke outlet 21.

[0061] When the fan 3 is working, a negative pressure is formed in the smoke collecting chamber 11, and the exhaust gas from the combustion of the stove and the oil smoke and other gases generated during the cooking process are gathered in the smoke collecting chamber 11 and enter the shell 1 through the smoke inlet 12. The oil smoke and other gases in the shell 1 enter the main box 2 from the oil smoke outlet 13, and flow to the smoke outlet 21 through the air inlet 31 and the air outlet 32 ​​of the fan 3 in turn, and are discharged from the smoke outlet 21, so as to reduce the amount of exhaust gas and oil smoke in the kitchen environment and improve the air quality of the kitchen.

[0062] The range hood may include an oil cup 5 , which is disposed at the bottom of the housing 1 to collect oil flowing down the inner wall of the housing 1 .

[0063] After the oil smoke and other gases flow into the main box body 2, some oil droplets in the oil smoke will adhere to the inner wall of the main box body 2 and the outer wall of the fan 3. As the amount of attached oil droplets gradually increases, the oil droplets will converge into an oil flow and flow downward to the inner wall of the shell 1 or the partition 4.

[0064] The oil flowing to the partition 4 flows along the partition 4 to the edge of the partition 4 close to the oil fume outlet 13, flows from the edge to the inner wall of the shell 1, and finally flows along the inner wall of the shell 1 to the oil cup 5 to be collected.

[0065] A buffer structure is constructed on the top of the partition 4 . The buffer structure protrudes from the partition 4 , and the buffer structure is spaced apart from the periphery of the partition 4 .

[0066] The buffer structure protrudes from the partition 4, so it can increase the resistance of the oil flowing toward the oil fume outlet 13, thereby slowing down the flow rate of the oil flowing from the partition 4 to the oil fume outlet 13. In this way, the flow rate of the oil on the partition 4 decreases when it flows to the edge of the oil fume outlet 13, so that the oil flow can slowly flow down along the inner wall of the shell 1, and the oil flow is not easy to quickly flow into the oil fume outlet 13 from the edge of the partition 4, and it is not easy to separate from the inner wall of the shell 1 and drip from the smoke inlet 12 onto the kitchen countertop.

[0067] The buffer structure and the periphery of the partition plate 4 are spaced apart so that the oil flow can flow from the gap between the buffer structure and the periphery of the partition plate 4 to the oil fume outlet 13, thereby reducing oil retention.

[0068] The range hood in this embodiment includes a housing 1, a main box 2 and a partition 4, wherein the main box 2 is arranged at the top of the housing 1, the partition 4 is arranged between the main box 2 and the housing 1, and the partition 4 and the housing 1 are arranged to form a fume outlet 13 connected to the main box 2; a buffer structure is constructed on the top of the partition 4, the buffer structure protrudes from the partition 4, and the buffer structure is arranged at intervals from the periphery of the partition 4. Through the above arrangement, the buffer structure can increase the resistance of the oil flow when it flows toward the fume outlet 13, so as to slow down the flow rate of the oil flow from the partition 4 to the fume outlet 13, so that the flow rate of the oil flow on the partition 4 decreases when it flows to the edge of the fume outlet 13, so that the oil flow can flow slowly down along the inner wall of the housing 1, and the oil flow is not easy to quickly flow into the fume outlet 13 from the edge of the partition 4, and thus it is not easy to separate from the inner wall of the housing 1 and drip from the fume inlet 12 onto the kitchen countertop.

[0069] In some possible implementations of the present application, reference is made to Figure 2 , Figure 4 and Figure 7 The buffer structure may be a buffer belt 41 , and both ends of the buffer belt 41 extend toward both sides of the partition 4 , that is, one side of the buffer belt 41 faces the oil fume outlet 13 , and the other side faces away from the oil fume outlet 13 .

[0070] The side of the buffer belt 41 away from the oil fume outlet 13 can increase the resistance of the oil flow toward the oil fume outlet 13, thereby slowing down the flow rate of the oil flow. The oil flow blocked by the buffer belt 41 can flow from the gap between the two ends of the buffer belt 41 and the partition 4 to the edge of the oil fume outlet 13.

[0071] In some possible implementations of the present application, reference is made to Figure 2 , the buffer belt 41 can extend along a curve. For example, the buffer belt 41 can protrude in a direction away from the oil fume outlet 13, that is, the middle of the buffer belt 41 is farther away from the oil fume outlet 13 than the two ends. In this way, the buffer belt 41 can not only slow down the flow rate of the oil flow, but also guide the blocked oil flow, so that the oil flow gradually flows along the buffer belt 41 toward the two sides of the partition 4 and the oil fume outlet 13, reducing the oil retention on the side of the buffer belt 41 away from the oil fume outlet 13.

[0072] In some possible implementations of the present application, the buffer belt 41 may extend along the fold line. For example, the buffer belt 41 may be in a "V" shape, and the middle of the buffer belt 41 is farther away from the oil fume outlet 13 than the two ends. The buffer belt 41 can not only slow down the flow rate of the oil flow, but also guide the blocked oil flow, so that the oil flow gradually flows along the buffer belt 41 toward the two sides of the partition 4 and the oil fume outlet 13, thereby reducing the oil retention on the side of the buffer belt 41 away from the oil fume outlet 13.

[0073] In some possible implementations of the embodiments of the present application, the buffer zone 41 may extend along a straight line to simplify the structure of the buffer zone 41 and facilitate the processing and manufacturing of the partition 4 .

[0074] In some possible implementations of the present application, reference is made to Figure 2 There can be multiple buffer strips 41, and the multiple buffer strips 41 can be arranged at intervals along the direction from the side away from the oil fume outlet 13 to the side close to the oil fume outlet 13. The multiple buffer strips 41 can improve the buffering effect on the oil flow velocity, so that the oil flow can slowly flow downward along the edge of the partition 4 close to the oil fume outlet 13 to the inner wall of the shell 1, and it is not easy for the oil flow to quickly gush out and drip from the smoke inlet 12.

[0075] In some possible implementations of the embodiments of the present application, the buffer structure may be a buffer boss, and there may be multiple buffer bosses, which are arranged at intervals, and the buffer bosses may slow down the flow rate of part of the oil flow from the side of the partition 4 away from the oil fume outlet 13 to the oil fume outlet 13. The oil flow blocked by the buffer boss has a reduced flow rate and then bypasses the buffer boss to flow to the edge of the oil fume outlet 13.

[0076] In some possible implementations of the present application, reference is made to Figure 6 , Figure 7 and Figure 8 The end of the partition 4 close to the oil fume outlet 13 has a first flange 42 extending downward, and a first connection hole 421 is configured on the first flange 42. Part of the housing 1 is attached to the side of the first flange 42 away from the oil fume outlet 13, and the housing 1 is configured with a second connection hole 14. The first flange 42 and the housing 1 are connected by a first fastening bolt 15 penetrating the first connection hole 421 and the second connection hole 14.

[0077] An oil-blocking structure may be constructed on the top of the partition 4, and the oil-blocking structure is close to the first flange 42. The two ends of the oil-blocking structure along the extension direction of the first flange 42 are located on both sides of the first connecting hole 421, and there is a gap between the oil-blocking structure and the first connecting hole 421. In this way, the oil-blocking structure can guide the oil flow on the partition 4 near the first connecting hole 421, so that the oil flow flows along the two ends of the oil-blocking structure to the two sides of the first connecting hole 421, and is not easy to flow into the first connecting hole 421, and thus is not easy to flow from the first connecting hole 421 to the outside of the shell 1 or even drip onto the kitchen countertop.

[0078] In some possible implementations of the present application, reference is made to Figure 2 , Figure 7 and Figure 8The oil-blocking structure may be an oil-blocking belt 43, the oil-blocking belt 43 protrudes from the partition 4, the oil-blocking belt 43 may extend along a curve, the oil-blocking belt 43 may protrude in a direction away from the oil fume outlet 13, both ends of the extension direction of the oil-blocking belt 43 extend to the first flange 42, and the first connecting hole 421 is located between the two ends of the extension direction of the oil-blocking belt 43.

[0079] The side of the oil blocking belt 43 facing away from the oil fume outlet 13 can guide the oil flow, so that the oil flow flows along the oil blocking belt 43 to both ends of the oil blocking belt 43 , thereby reducing the possibility of the oil flow flowing into the first connecting hole 421 .

[0080] Both ends of the oil-blocking belt 43 in the extension direction extend to the first flange 42, so that there is no gap between the two ends of the oil-blocking belt 43 and the first flange 42, so that the oil-blocking belt 43 can directly guide the oil flow to the first flange 42, making it difficult for the oil flow to flow to the side of the oil-blocking belt 43 facing the oil fume outlet 13, thereby reducing the possibility of the oil flow flowing into the first connecting hole 421.

[0081] In some possible implementations of the embodiments of the present application, the oil-blocking structure may be an oil-blocking boss, which protrudes from the partition 4, and the two ends of the oil-blocking boss along the extension direction of the first flange 42 are located on both sides of the first connecting hole 421, and there is a gap between the oil-blocking boss and the first connecting hole 421, so that the oil-blocking boss can guide the oil flow on the partition 4 near the first connecting hole 421, so that the oil flow flows along the two ends of the oil-blocking boss to the two sides of the first connecting hole 421, and is not easy to flow into the first connecting hole 421.

[0082] In some possible implementations of the present application, reference is made to Figure 7 and Figure 8 A first connecting column 422 may be provided on a side of the first flange 42 facing the oil fume outlet 13 , and the first connecting hole 421 is configured on the first connecting column 422 .

[0083] Since the first connecting column 422 protrudes from the first flange 42, when the oil on the surface of the first flange 42 flows along the first flange 42, it is not easy to flow to the end of the first connecting column 422 away from the first flange 42. Therefore, the difficulty of the oil flowing into the first connecting hole 421 is increased, making it difficult for the oil to flow into the first connecting hole 421, and further making it difficult for the oil to flow from the first connecting hole 421 to the outside of the shell 1 or even drip onto the kitchen countertop.

[0084] In some possible implementations of the present application, reference is made to Figure 4 , Figure 7 and Fig. 9 The partition plate 4 has two second flanges 44 arranged opposite to each other, and the second flanges 44 extend upward.

[0085] The main box body 2 is arranged above the partition 4, and the bottom of the main box body 2 has a third flange 22, which extends to the outside of the main box body 2, is located inside the second flange 44, and is connected to the partition 4. In this arrangement, the inner wall of the main box body 2 and the projection of the third flange 22 on the partition 4 are both located on the partition 4 and inside the second flange 44, so the oil flowing down from the inner wall of the main box body 2 can be received by the partition 4, and the second flange 44 can prevent the oil from flowing outside the partition 4, thereby reducing the possibility that the oil flowing down from the inner wall of the main box body 2 flows to other areas outside the partition 4.

[0086] In some possible implementations of the present application, reference is made to Fig. 9 The edge of the partition plate 4 close to the third flange 22 may be configured with a first boss 45 protruding upward, and the top of the first boss 45 is configured with a third connecting hole 451 .

[0087] The third flange 22 is configured with a second boss 23 protruding upward, the second boss 23 is arranged outside the first boss 45, and a fourth connection hole 24 is configured at the top of the second boss 23. The partition 4 and the third flange 22 are connected by a second fastening bolt 25 penetrating the third connection hole 451 and the fourth connection hole 24.

[0088] The first boss 45 protrudes from the partition 4, so that the height of the third connecting hole 451 is higher than the upper surface of the partition 4, so that the oil on the partition 4 is not easy to flow into the third connecting hole 451, and then it is not easy to flow out of the third connecting hole 451 or even drip onto the kitchen countertop.

[0089] In some possible implementations of the present application, reference is made to Fig. 9 The main box body 2 may have a fourth flange 26 , the fourth flange 26 is located at the end of the third flange 22 , the fourth flange 26 extends upward, and the fourth flange 26 is located on the inner side of the second flange 44 .

[0090] The fourth flange 26 can reduce the difficulty of the oil flowing out from between the third flange 22 and the partition 4 to flow to the top of the third flange 22 .

[0091] In some possible implementations of the present application, reference is made to Figure 6 and Fig.10 The end of the partition 4 away from the oil fume outlet 13 may have a fifth flange 46 , and the fifth flange 46 extends upward. The fifth flange 46 prevents oil from flowing out from the side of the partition 4 away from the oil fume outlet 13 .

[0092] A fifth connecting hole 461 may be formed on the fifth flange 46 .

[0093] Part of the main box body 2 is fitted to the side of the fifth flange 46 facing the oil fume outlet 13, and a second connecting column 27 can be provided on the side of the main box body 2 away from the fifth flange 46. The second connecting column 27 is constructed with a sixth connecting hole 28, and the sixth connecting hole 28 corresponds to the fifth connecting hole 461. A third fastening bolt 29 is passed through the fifth connecting hole 461 and the sixth connecting hole 28.

[0094] Since the second connecting column 27 protrudes from the inner wall of the main box body 2, when the oil on the inner wall of the main box body 2 flows along the inner wall of the main box body 2, it is not easy to flow to the end of the second connecting column 27 away from the fifth flange 46. Therefore, the difficulty of the oil flowing into the sixth connecting hole 28 is increased, making it difficult for the oil to flow into the sixth connecting hole 28, and further making it difficult for the oil to flow from the sixth connecting hole 28 to the outside of the main box body 2 or even drip onto the kitchen countertop.

[0095] In some possible implementations of the present application, reference is made to Figure 7 The fifth flange 46 can be connected to the second flange 44 so that there is no gap between the fifth flange 46 and the second flange 44, so that the oil on the partition 4 is not easy to flow out from the edge of the partition 4.

[0096] In summary, the range hood of the embodiment of the present application includes a housing 1, a main box 2 and a partition 4, the main box 2 is arranged on the top of the housing 1, the partition 4 is arranged between the main box 2 and the housing 1, and the partition 4 and the housing 1 are arranged to form a fume outlet 13 connected to the main box 2; a buffer structure is constructed on the top of the partition 4, the buffer structure protrudes from the partition 4, and the buffer structure is arranged at intervals from the periphery of the partition 4. Through the above arrangement, the buffer structure can increase the resistance of the oil flow when it flows to the fume outlet 13, so as to slow down the flow rate of the oil flow from the partition 4 to the fume outlet 13, so that the flow rate of the oil flow on the partition 4 decreases when it flows to the edge of the fume outlet 13, so that the oil flow can slowly flow down along the inner wall of the housing 1, and the oil flow is not easy to quickly flow into the fume outlet 13 from the edge of the partition 4, and thus it is not easy to separate from the inner wall of the housing 1 and drip from the smoke inlet 12 onto the kitchen countertop.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it.
