DESCRIPTION OF THE EMBODIMENTS

(5) To enable a further understanding of the present invention content of the invention herein, refer to the detailed description of the invention and the accompanying drawings below.

Embodiment 1

(6) FIGS. 1-3 show a wind outlet mechanism for a range hood of an Embodiment 1 of the present invention. The wind outlet mechanism comprises a wind pipe 1a with a wind outlet 1, a decorative cover 2 and a flow guide member 3.

(7) In this embodiment, the wind pipe 1a has a top end formed with an upward opening, and the wind outlet 1 is formed on the top end of the wind pipe 1a. Of course, the wind outlet 1 may also be formed by another portion of the wind pipe 1a or another component used for exporting an air flow from the range hood.

(8) The decorative cover 2 is disposed around an outer periphery of the wind outlet 1 to shield the top end of the wind pipe 1a, and the decorative cover 2 has a plurality of wind discharge holes 20.

(9) The flow guide member 3 is disposed inside the decorative cover 2, and the flow guide member 3 has a cambered flow guide surface 30 opposite to and protruding toward the wind outlet 1. In this embodiment, the flow guide surface 30 is shaped as a circular arc. In this way, when an air flow is directly blown from the wind outlet 1 to the flow guide surface 30 from bottom to up, the flow guide surface 30 can guide the air flow to a horizontal direction so that the air flow is discharged from the wind discharge holes 20 on the decorative cover 2, thereby reducing direct plane reflection. Moreover, the wind outlet mechanism in this embodiment is not obviously limited in space, and the internal space in the decorative cover 2 can be fully utilized to provide a larger buffer region for discharging wind. Accordingly, the wind discharge resistance becomes low, the wind discharge rate at the wind discharge holes 20 can be effectively reduced, and the noise is thus reduced.

(10) In this embodiment, the flow guide member 3 is a circular plate, and the flow guide surface 30 is located at a bottom side of the flow guide member 3 and protrudes downward. To conveniently mount the flow guide member 3, a mounting bracket 4 for the flow guide member 3 be mounted above a side wall of the wind outlet 1 is disposed between the wind pipe 1a and the flow guide member 3 inside the decorative cover 2. The mounting bracket 4 may be implemented specifically in various ways. In this embodiment, the mounting bracket 4 comprises at least two connecting poles 41 having two ends, one end of each connecting pole 41 is connected with the flow guide member 3 and the other end each connecting pole 41 is connected with the end of the wind pipe 1a. Correspondingly, the flow guide member 3 has at least two mounting ears 31 protruding from the circular edge of the flow guide member 3 at intervals, and each mounting ear 31 is connected with a corresponding connecting pole 41. An upper end portion of each connecting pole 41 is bent to form a connecting portion 411 extending outward in a horizontal direction, and each connecting portions 411 is fixed with the mounting ears 31 by screws.

(11) Further, in this embodiment, the decorative cover 2 comprises a front side plate 21, a left side plate 22 and a right side plate 23, each side plate has the wind discharge holes 20, and the wind discharge holes 20 on each side plate are flush with each other. The flow guide member 3 is located corresponding to the position of the wind discharge holes 20.

Embodiment 2

(12) FIG. 4 shows Embodiment 2 of the present invention. This embodiment differs from the Embodiment 1 in that: in this embodiment, an adsorption medium layer 5 for adsorbing fume is arranged on a bottom surface of the flow guide surface 30. The adsorption medium layer 5 can adsorb part of residual fume discharged from the wind outlet 1. Moreover, since there are many voids on a surface of the adsorption medium, the overall noise generated when discharging wind can be further reduced by decreasing the speed of air passing through the surface of the adsorption medium.
