Example 1

Referring to fig. 1-2, the present embodiment provides a smoke collecting hood of a range hood, which includes a smoke collecting hood inner cover 1 and a smoke collecting hood outer cover 2, a first smoke collecting through hole 15 is opened on the smoke collecting hood inner cover 1, a front end of the smoke collecting hood inner cover is bent downward to form a front panel 11, and a free end of the front panel 11 is bent forward and outward to form a first matching portion 12. The fume collecting hood 2 comprises a bottom plate 21, a sinking platform 2101 is arranged on the bottom plate 21, a second fume collecting through hole 25 is arranged at the position, corresponding to the first fume collecting through hole 15, of the sinking platform 2101, and the first matching part 12 is at least partially arranged on the sinking platform 2101.

In this embodiment, the first engaging portion 12 includes a horizontal engaging portion disposed horizontally and an inclined engaging portion disposed obliquely (not shown in the figure), the horizontal engaging portion is attached to the end surface of the sinking platform 2101, a round corner reinforcing portion 13 is disposed at a bending position between the front panel 11 and the first engaging portion 12, and the round corner reinforcing portion 13 includes a plurality of round corners with different sizes.

In this embodiment, the sinking platform 2101 has two sides (not shown in the figure) located at the left and right outer sides of the second smoke collecting through hole 25, each side includes a transverse side edge 2103 and a vertical side edge 2102 connected, and the upper end of the vertical side edge 2102 is fixedly connected to the side of the transverse side edge 2103 far away from the second smoke collecting through hole 25. The fillet reinforcement 13 is the largest in angle of the fillet at the vertical side edge 2102 facing the sink deck, and the fillet reinforcement 13 is a gradual fillet whose angle is gradually decreased from the vertical side edge 2103 to the left and/or right of the vertical side edge 2103. The setting of the vertical side edge 2102 that the biggest radius angle R angle corresponds to collection petticoat pipe dustcoat 2 can effectively avoid falling the impact, and its reason lies in: when the range hood falls, the vertical side edge 2102 of the sinking platform 2101 on the fume collecting hood outer cover 2 is concentrated by the impact force of the fume collecting hood inner cover 1, so that the oil net sinking platform 2101 of the fume collecting hood outer cover 2 deforms; the fillet strengthening part 13 changes the fillet sketch map gradually, as shown in fig. 3 and 4, except that the fillet of two vertical side edges 2102 near the oil net sinking platform 2101 of the exhaust fume collecting hood outer cover 2 is the largest on the exhaust fume collecting hood inner cover 1, the fillet of other positions gradually becomes smaller, namely, the farther from the vertical side edge 2102 of the oil net sinking platform 2101, the smaller the fillet R angle is, and the size of the gradually changed fillet is favorable for reducing the whole flanging angle of the inner cover. The maximum fillet value Rmax is more than or equal to 0.01 time of impact force F, the maximum R angle is correspondingly increased as the falling height is higher, for example, the falling height H =0.5M, the falling time T =0.1s, the impact force F = mv/T, the whole machine weight is 32KG, the impact speed V2=2Gh, V =3.1m/s, the impact force =1001N, and the maximum fillet change R is approximately equal to 0.01F =10mm.

Preferably, the first fitting portion 12 is provided with a notch 27 at a position corresponding to the vertical side edge, and in the present embodiment, the notch 27 is provided between the horizontal fitting portion and the inclined fitting portion to facilitate the manufacturing of the maximum rounded corner R.

Preferably, the fillet radius of the fillet reinforcing part 13 ranges from 2mm to 12mm. With the present embodiment, the maximum fillet of the fillet reinforcement is 10mm, the minimum fillet is R =3mm, and the fillet radius of the fillet reinforcement gradually decreases from the maximum fillet position to both sides.

Referring to fig. 2, a panel 21 is horizontally arranged on the fume collecting hood housing 2, the fume collecting hood housing 2 is further provided with two second inner concave portions 22 located on the left and right outer sides of the panel 21, each second inner concave portion 22 is concave upwards and is open downwards, the second inner concave portions 22 form an inclined plane which is obliquely arranged in the vertical direction, each inclined plane can be obliquely arranged from right to left or from left to right, and the two inclined planes enclose and close to form a shape like a Chinese character 'ba' or a shape like a reversed 'ba'. A third fume collecting through hole 23 is formed in each inclined surface, and the third fume collecting through holes 23 are communicated with the first fume collecting through holes 15. First collection cigarette through-hole 15 forms the oil smoke passageway with second collection cigarette through-hole 25 jointly, and third collection cigarette through-hole 23 forms supplementary inlet air channel, and when foretell oil smoke passageway can promote lampblack absorber intake, owing to be provided with the interior recess 22 of second that the die mould formed, it is equivalent to be formed with the pressure type additional strengthening in collection petticoat pipe outer cover 2 both sides, does benefit to the bulk strength that further promotes collection petticoat pipe.

Referring to fig. 1, further, the fume collecting hood inner cover 1 is provided with a first concave part 17 which is concave downwards and is open upwards corresponding to the third fume collecting through hole 23, the bottom end face of the first concave part 17 is a fume guide plate 1701 which is parallel to the third fume collecting through hole 23, similarly, as the first concave part 17 is arranged on the fume collecting hood inner cover, and the fume guide plate 1701 is formed at the bottom end face of the first concave part 17, it can improve the fume guide effect of the fume collecting hood, and at the same time, the first concave part is equivalent to a profiling reinforcing structure, and the whole strength of the fume collecting hood can be improved.

In addition, at least one reinforcing sheet 1101 arranged vertically is provided on the front panel 11, and the reinforcing sheet 1101 penetrates the front panel 11 in the vertical direction. In the present embodiment, two reinforcing sheets are disposed on the front panel 11 at intervals, and each reinforcing sheet 1101 is integrally formed forward from a part of the front panel 11. The rear end of the exhaust fume collecting hood inner cover 1 is bent downward to form a rear panel 14, and a profiling reinforcing part is arranged on the rear panel 14 to reinforce the strength of the rear panel. Still be provided with on the collection petticoat pipe inner cover 1 and be located two protruding rib 16 in two outsides about first collection cigarette through-hole, two protruding rib 16 are located two first interior concave parts 17 respectively and keep away from one side of first collection cigarette through-hole to strengthen the intensity of the inner cover left and right sides, of course, can also set up protruding rib 16 respectively between first interior concave part 17 and first collection cigarette through-hole. Further, two outside bends up and form side board 26 about collection petticoat pipe dustcoat 2, are formed with draw-in groove 24 between side board 26 and the panel 21, during the installation, back panel 14 and draw-in groove 24 cooperation are with chucking collection petticoat pipe inner cover 1, still are provided with first installation department (not shown in the figure) on the collection petticoat pipe inner cover, be provided with on the collection petticoat pipe dustcoat 2 with first installation department complex second installation department (not shown in the figure), collection petticoat pipe inner cover 1 and collection petticoat pipe dustcoat 2 accomplish the assembly through first installation department and second installation department cooperation.

Example 2

The utility model provides a range hood, is including foretell range hood collection petticoat pipe, and range hood collection petticoat pipe is connected in the range hood main part, and at the in-process of transportation, because range hood installs range hood collection petticoat pipe, when range hood collection petticoat pipe falls, can not warp because of falling the impact force that brings, and its anti ability of falling is stronger.
