[0035] As Figures 1-3 As shown, an embodiment of the present application provides a range hood, which mainly includes a smoke collecting hood 1. The smoke suction side of the smoke collecting hood 1 has a recess 11, and a diversion arc surface 12, an air outlet 13 and a suction port 14 are arranged in the recess 11. Among them, the air inlet side of the diversion arc surface 12 corresponds to the air outlet 13, and the air outlet side of the diversion arc surface 12 corresponds to the suction port 14, so as to form a rotating airflow for gathering smoke in the recess 11.

[0036] In some possible embodiments, the smoke collecting hood 1 is horizontally arranged. The bottom side of the smoke collecting hood 1 is the smoke suction side, and the suction port 14 is the smoke suction inlet. The bottom of the smoke collecting hood 1 has a recess 11 that is recessed towards the top of the smoke collecting hood 1. The diversion arc surface 12 is used to guide the airflow to flow from one side of the arc surface to the opposite side. The rotating airflow is formed in the recess 11 and is close to the diversion arc surface 12.

[0037] Through the range hood provided by the embodiment of the present application, the airflow discharged from the air outlet 13 flows along the diversion arc surface 12 to form a turning airflow. Under the suction of the suction port 14 and the pushing of the air outlet, the turning airflow forms a rotating airflow, and the rotating airflow draws the sucked-up smoke into the rotating airflow. Among them, a part of the rotating airflow is sucked into the inside of the smoke collecting hood 1 through the suction port 14 and discharged, and another part of the rotating airflow will continue to rotate and flow, avoiding the escape of smoke. In this way, the effect of gathering smoke can be achieved in a relatively small occupied space, thereby improving the smoking efficiency and achieving the purpose of improving the user experience.

[0038] As Figure 2As shown, as an alternative embodiment, a bottom plate 15 and side plates 16 disposed on opposite sides of the bottom plate 15 are further provided within the recess 11, and the two side plates 16 and the bottom plate 15 form a structure that is lower on both sides and higher in the middle; the guiding arc surface 12 is connected to one side of the bottom plate 15 and is connected to the side plates 16, and the concave side of the guiding arc surface 12 faces the bottom plate 15; wherein, the air outlet 13 is opened at the connection of the bottom plate 15 and the guiding arc surface 12; the air suction port 14 is opened on the bottom plate 15.

[0039] Based on the foregoing embodiments, some possible embodiments are provided. Both the bottom plate 15 and the side plates 16 are flat plate structures. The side plates 16 are disposed on the left and right sides of the bottom plate 15, and the side plates 16 and the bottom plate 15 are connected at an angle. The guiding arc surface 12 is located on the guiding arc plate, and the guiding arc plate is disposed on the front side of the bottom plate 15. The bottom plate 15, the side plates 16, and the guiding arc surface 12 enclose the concave structure of the recess 11, and a rotating air flow is formed at the front side within the recess 11. The air outlet 13 is opened at the connection of the bottom plate 15 and the guiding arc surface 12, so as to ensure that the air outlet can flow towards the guiding arc surface 12 at a more appropriate angle, reduce the loss of wind energy, and thereby increase the smoke gathering ability of the rotating air flow. The air suction port 14 is opened on the bottom plate 15 and the concave side of the guiding arc surface 12 faces the bottom plate 15, which can guide the air flow flowing along the turning direction towards the bottom plate 15. Under the suction of the air suction port 14 and the pushing action of the air outlet 13, a rotating air flow can be formed between the bottom plate 15 and the guiding arc surface 12, and the rotating air flow rotates circumferentially, for example: clockwise rotation or counterclockwise rotation.

[0040] As Figure 2 As shown, as an alternative embodiment, a connecting plate 17 is further provided within the recess 11. The connecting plate 17 is connected to the bottom plate 15 and the guiding arc surface 12, and the connecting plate 17 faces the air inlet side of the guiding arc surface 12; wherein, the air outlet 13 is opened on the connecting plate 17 and faces the air inlet side of the guiding arc surface 12.

[0041] Based on the foregoing embodiments, some possible embodiments are provided. The connecting plate 17 is a flat plate structure. The connecting plate 17 is disposed between the plate and the guiding arc surface 12. The air outlet 13 penetrates through the connecting plate 17 along the thickness direction of the connecting plate 17, so that the air outlet 13 can face the air inlet side of the guiding arc surface 12, enabling the air outlet air flow to flow towards the guiding arc surface 12 at a suitable angle. Among them, the air inlet side of the guiding arc surface 12 is the side of the guiding arc surface 12 close to the bottom plate 15, and the air outlet side of the guiding arc surface 12 is the side of the guiding arc surface 12 far from the bottom plate 15.

[0042] Optionally, the air outlet direction of the air outlet 13 is the horizontal direction.

The cooking fume can flow towards the smoke collecting hood 1 in the vertically upward direction, that is, the first direction L1 can be the vertically upward direction. The second direction L2 can be the horizontal direction.

[0045] Both the bottom plate 15 and the side plate 16 are arranged at an angle with the first direction L1.

[0046] As Figure 2 shown, the air suction port 14 penetrates through the bottom plate 15 along the thickness direction of the bottom plate 15.

[0047] The air outlet 13 can be an opening that extends along the second direction L2; the air outlet 13 can also include a plurality of sub-openings arranged along the second direction L2; the guide arc surface 12 corresponds to the air outlet 13 and extends along the second direction L2, so that the formed rotating air flow extends along the second direction L2, increasing the smoke gathering effect on the flue gas from the first direction L1. Among them, the rotating air flow rotates around its rotation axis, and the second direction L2 is the extension direction of the rotation axis of the rotating air flow.

[0048] As an alternative implementation, the angle formed by the tangent line of the air outlet side edge of the guide arc surface 12 and the first direction L1 is not greater than 15 degrees. This can limit the formation position of the rotating air flow, prevent the rotating air flow from being too outward, reduce the smoke gathering effect, and cause the flue gas to escape.

The air guide box 6 can change the exhaust direction of the exhaust fan 2, and the position of the exhaust fan 2 can be set more flexibly.

[0051] In a specific embodiment, the range hood includes four exhaust fans 2. Taking two exhaust fans 2 as a group, the two groups of exhaust fans 2 are arranged at intervals. The air inlets of the exhaust fans 2 are arranged upward, and air inlets 19 of the smoke collecting hood 1 are provided at corresponding positions on the cover wall of the smoke collecting hood 1 above the exhaust fans 2.

[0052] As Figure 5 shown, as an alternative embodiment, the range hood further includes a baffle 3. The baffle 3 is arranged in the cavity 18 of the smoke collecting hood 1. The baffle 3 is arranged at an interval from the bottom plate 15. The baffle 3 is provided with through holes, and the through holes of the baffle 3 correspond to the air suction openings 14.

[0053] As an alternative embodiment, the distance between the baffle 3 and the bottom plate 15 is greater than or equal to 10 millimeters and less than or equal to 40 millimeters.

[0054] Based on the foregoing embodiments, some possible embodiments are provided.
