Detailed Description

The utility model is described in further detail below with reference to the embodiments of the drawings.

As shown in fig. 1 to 7, the lifting type range hood of the present embodiment includes a fan frame and a range hood 2 mounted inside the fan frame 1, an outer case 3 is mounted outside the fan frame 1, the range hood adopts a structure on a lower bag, that is, the outer case 3 wraps the fan frame 1, and the outer case 3 can move up and down relative to the fan frame 1 under the driving of a driving mechanism 5. The outer box 3 installs fume collecting hood 4 in the bottom, and it has smoke inlet 41 to open on fume collecting hood 4, installs oil cup 9 in fume collecting hood 4's bottom, and the periphery portion of smoke inlet 41 is formed with leads oil groove 42, leads the oil in the oil groove 42 and can flow into in the oil cup 9. The oil guide groove 42 may be a separate component or may be integrated with the fume collecting hood 4.

The first plate 6 is installed at the bottom of the fan frame 1, and the second plate 7 is installed at the smoke inlet 41. In this embodiment, the first plate body 6 and the second plate body 7 are square plates and have the same size, and the first plate body 6 and the second plate body 7 are all horizontally arranged, that is, the first plate body 6 and the second plate body 7 are parallel to each other, so that the smoke inlet 41 forms a smooth appearance, which is beneficial to reducing noise. The first plate body 6 is provided with a first air inlet hole 61, the second plate body 7 is provided with a second air inlet hole 71, and the first air inlet hole 61 and the second air inlet hole 71 are distributed in a staggered manner on vertical projection. In addition, on the basis of satisfying the staggered openings, the first plate body 6 and the second plate body 7 may be arranged in an inclined manner, in addition to the horizontal arrangement.

As shown in fig. 4 and 5, the driving mechanism 5 of the present embodiment includes an electric push rod 51 provided on the blower housing 1 and a connection block 52 mounted at an output end of the electric push rod 51, and the outer casing 3 is fixed on the connection block 52 and moves up and down synchronously with the connection opening under the driving of the electric push rod 51. In order to make the lifting of the outer case 3 smoother, the electric push rod 51 of this embodiment is mounted at a position centered on the left and right of the back of the fan frame 1, and the left and right side walls of the fan frame 1 are mounted with guide rails 53, and the left and right sides of the outer case 3 are respectively slidably disposed on the guide rails 53 on the corresponding sides.

In operation, the outer casing 3 is driven by the electric push rod 51 to move up and down along the guide rail 53 relative to the fan frame 1. In the raised state of the outer casing 3, the first plate 6 and the second plate 7 overlap with each other, and at this time, since the projections of the openings of the first air inlet hole 61 and the second air inlet hole 71 are staggered, the smoke inlet 41 can be closed, the oil path of the range hood can be closed, and the oil in the oil guide groove 42 can smoothly flow into the oil cup. Under the outer box 3 decline state, first plate body 6 and second plate body 7 keep away from each other, form into cigarette passageway 8 between first plate body 6 and the second plate body 7, when outer box 3 descends to the bottom, the distance between first plate body 6 and the second plate body 7 is biggest, advances cigarette passageway 8 and forms deep cavity structure, does benefit to and improves the oil absorption effect. In addition, the second plate 7 is provided with a second air inlet hole 71, so that the section of the air duct is reduced, the smoke inlet speed is increased, and the smoke absorbing effect is better.
