Along a first direction X and directed from the back panel 14 towards the top panel 13, the first smoke-guiding plate 5 is at least partially inclined towards a direction close to the axis L1 of the back panel 14.

In this way, when the range hood 100 is in operation, the air flow entering the air suction cavity 171 from the first air inlet 11 is guided to the air outlet 12 by the inclined portion of the first smoke guide plate 5 after striking the inclined portion of the first smoke guide plate 5, and is discharged through the air outlet 12. Thus, the soot entering the suction chamber 171 can be more quickly discharged from the suction chamber 171. In this way, the residence time of the soot in the suction cavity 171 can be shortened, thereby reducing the soot entering the installation cavity 172 through the threading holes on the soot-separating plate 3, and reducing the soot entering the control panel 4.

As shown in fig. 11, the first smoke-guiding plate 5 may include a first sub-smoke-guiding plate 51 and a second sub-smoke-guiding plate 52. The first sub-smoke-guiding plate 51 is connected to the edge of the air outlet 12. Along the first direction X and directed from the back panel 14 towards the top panel 13, the first sub-smoke-guiding plate 51 is at least partially inclined towards a direction close to the axis L1 of the back panel 14. It will be appreciated that the first sub-smoke-guiding plate 51 is capable of guiding the soot entering from the first air inlet 11 to the air outlet 12 to reduce the residence time of the soot in the suction cavity 171.

On the basis, the second sub-smoke-guiding plate 52 is disposed on the side of the first sub-smoke-guiding plate 51 away from the top plate 13 and is connected to the first sub-smoke-guiding plate 51. The end of the second sub-smoke-guiding plate 52 remote from the first sub-smoke-guiding plate 51 is connected to the side plate 15. The surface of the second sub-smoke-guiding plate 52 near the axis of the back plate 14 is perpendicular to the surface of the top plate 13 near the back plate 14 and perpendicular to the surface of the back plate 14 near the side plate 15.

In this way, when the oil smoke flows into the suction cavity 171 from the first air inlet 11, the second smoke guide plate 6 can block the oil smoke at the first air inlet 11, so as to reduce the risk of the oil smoke leakage of the range hood 100, and improve the use experience of a user.

The first sub-smoke-guiding plate 51 and the second sub-smoke-guiding plate 52 may be integrally formed, or may be two independent members, and may be connected together by welding, riveting, screwing, snap-fastening, or the like. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

Illustratively, as shown in fig. 13, fig. 13 is a block diagram of a first smoke-guiding plate according to some embodiments of the present utility model. The first sub-smoke-guiding plate 51 and the second sub-smoke-guiding plate 52 are integrally formed. For example, the first sub-smoke guide plate 51 and the second sub-smoke guide plate 52 are formed by bending a same sheet material by a sheet metal process. In this way, the connection strength of the first sub-smoke-guiding plate 51 and the second sub-smoke-guiding plate 52 can be improved, and the manufacturing process of the first smoke-guiding plate 5 can be advantageously simplified.

The first sub-smoke-guiding plate 51 may include a connection portion 511 and a flow guiding portion 512. The connection portion 511 is connected to the edge of the air outlet 12, that is, the connection portion 511 is directly connected to the inner sidewall of the air outlet 12. In this way, the airflow can more smoothly flow out of the suction chamber 171 through the air outlet 12, and the risk of soot remaining at the junction between the connection portion 511 and the top plate 13 is reduced.

The guide portion 512 is disposed on a side of the connection portion 511 away from the top plate 13, and is connected to the connection portion 511. The end of the flow guiding portion 512 away from the connecting portion 511 is connected to the second sub-smoke-guiding plate 52. That is, the connection portion 511 is connected to the second sub-smoke guide 52 through the flow guide portion 512.

Note that, referring to fig. 12, the surface of the connection portion 511 near the axis L1 of the back plate 14 is perpendicular to the surface of the top plate 13 near the back plate 14 and perpendicular to the surface of the back plate 14 near the side plate 15. In this way, when the range hood 100 is in operation, the attractive force generated by the fan can be concentrated in the direction close to the air outlet 12, which is beneficial to increasing the attractive force of the range hood 100, thereby improving the effect of the range hood 100 in absorbing oil smoke.

In addition, along the first direction X and directed from the back plate 14 to the top plate 13, the distance between the flow guiding portion 512 and the axis L1 of the back plate 14 gradually decreases. Thus, the guiding portion 512 can perform guiding effect to guide the fume sucked by the range hood 100 to the air outlet 12.

Illustratively, as shown in fig. 14, fig. 14 is a block diagram of a first smoke-guiding plate according to some embodiments of the present utility model. The flow guiding portion 512 includes a bending portion 5121 and a main body portion 5122. The bending part 5121 is connected with the second sub smoke guide plate 52; the main body 5122 is connected to an end of the bending portion 5121 remote from the second sub-smoke-guiding plate 52, and an end remote from the bending portion 5121 is connected to the connecting portion 511.

Here, referring to fig. 12, the surface of the bending portion 5121 near the axis L1 of the back plate 14 is curved and is recessed toward the direction near the axis of the back plate 14. Along the first direction X and directed from the back plate 14 toward the top plate 13, the main body 5122 is inclined toward a direction approaching the axis L1 of the back plate 14.

By providing the bent portion 5121, the transition between the second sub-smoke-guiding plate 52 and the first sub-smoke-guiding plate 51 can be smoother. In this way, the resistance of the first smoke guide plate 5 to the air flow sucked by the range hood 100 can be reduced, and the air flow can be made smoother. In this way, the smoke guiding effect of the first smoke guiding plate 5 can be improved.

In some embodiments, as shown in fig. 12, the range hood 100 includes two first smoke guide plates 5, and the two first smoke guide plates 5 are symmetrically disposed with respect to the axis of the back plate 14. It will be appreciated that the provision of two first smoke guide plates 5 is advantageous for further improving the smoke absorbing effect of the extractor hood 100.

On the basis, referring to fig. 10, the range hood 100 may further include a second smoke guide plate 6, and the second smoke guide plate 6 is disposed in the suction chamber 171 and between the two first smoke guide plates 5. The second smoke-guiding plate 6 is connected to the end of the back plate 14 remote from the top plate 13. The second smoke-guiding plate 6 is inclined in a direction approaching the back plate 14 in a first direction and directed from the back plate 14 to the top plate 13.

In this way, the air flow sucked by the range hood 100 collides with the second smoke guide plate 6 at the first air inlet 11, and is changed in flow direction by the second smoke guide plate 6, and is guided to the air outlet 12. In this way, the time that the oil smoke stays in the suction chamber 171 can be further shortened, so that the risk of failure of the control panel 4 is reduced, and the service life of the range hood 100 is prolonged.

It should be noted that, as shown in fig. 15, fig. 15 is a structural diagram of a range hood according to some embodiments of the present utility model. The range hood 100 may further include an operation panel 7, and the operation panel 7 is disposed at a side of the control panel 4 (shown in fig. 10) remote from the back plate 14 and connected to the top plate 13 (shown in fig. 2), the side plate 15, and the connection plate 16. The operation panel 7 can input an operation command to control the control panel 4 to control the operation of the range hood 100.

In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.

The present utility model is not limited to the above embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
