Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

The embodiment provides a horizontally movable smoke collecting cavity mechanism, as shown in fig. 1, comprising a smoke collecting cavity body 1, a smoke collecting cover 2 and a driving assembly 3;

collection smoke chamber main part 1 is in through the flexible setting of sliding assembly 4 in the collection petticoat pipe 2, drive assembly 3 with collection smoke chamber main part 1 is connected, is used for the drive collection smoke chamber main part 1 for collection petticoat pipe 2 level is stretched out and is opened or is withdrawed and close, the bottom slope of collection smoke chamber main part 1 is provided with first air intake 11, the bottom slope of collection petticoat pipe 2 is provided with second air intake 21.

Specifically, drive assembly 3 set up in on the collection petticoat pipe 2, the other end with collection cigarette chamber main part 1 is connected, collection cigarette chamber main part 1 slides through sliding assembly 4 under drive assembly 3's drive, stretches out for collection petticoat pipe 2 level and opens or withdraws and close.

Like this, collection smoke chamber main part 1 is connected with collection petticoat pipe 2 through sliding assembly 4, and still is provided with drive assembly 3 between collection smoke chamber main part 1 and the collection petticoat pipe 2, and under drive assembly 3's drive action, collection smoke chamber main part 1 slides through sliding assembly 4 to carry out horizontal concertina movement for collection petticoat pipe 2.

As shown in fig. 1-3, a plurality of meshes are uniformly distributed on each of the first air inlet 11 and the second air inlet 21, and oil nets for passing oil smoke are provided, that is, the oil nets for passing oil smoke are provided on each of the first air inlet 11 and the second air inlet 21, and a plurality of meshes are uniformly distributed on the oil nets.

When the range hood is in a working state, the smoke collection cavity body 1 can horizontally extend and open relative to the smoke collection cover 2, the additionally extended smoke collection cavity body 1 can be used as a smoke collection cavity for collecting oil smoke, the range hood has the effect of collecting and absorbing the oil smoke similar to a top-suction range hood, the first air inlet 11 of the smoke collection cavity body 1 and the second air inlet 21 of the smoke collection cover 2 can intake air together, and the oil smoke can be absorbed better and more efficiently; the first air inlet 11 and the second air inlet 21 both present a certain inclination, and accumulated oil can flow into the oil guide groove along the inclination and flow into the oil cup through the oil leakage hole, so that good oil guide is realized.

When the range hood is in a closed state, the shape of the range hood is similar to that of a side-draught range hood, the range hood is concise in appearance and does not occupy additional space of a kitchen, and the first air inlet 11 in the bottom of the smoke collection cavity body 1 is in an inclined state, so that collected residual oil can be automatically recovered to the machine body under the action of gravity and flows into an oil cup.

Moreover, the smoke collecting cavity body 1 and the smoke collecting cover 2 can be respectively used as a main air inlet and an auxiliary air inlet, and the two air inlets are matched for secondary auxiliary smoking, so that the suction and exhaust capacity of the rear oil smoke is improved; meanwhile, the blocking effect of the smoke guide plate on the air inlet channel is reduced, and the air suction and exhaust quantity is ensured. In the cooking process of less oil smoke, only the second air inlet 21 at the bottom of the smoke collecting hood 2 is used for absorbing the oil smoke, namely, only the low gear of the range hood needs to be started to work, and the auxiliary air inlet of the smoke collecting hood 2 is used, so that a certain energy-saving effect is achieved.
