The embodiment discloses a range hood pipeline and a range hood comprising the same. As shown in fig. 1 and 2, the range hood pipeline comprises a flow guide component 2, a telescopic component 1 and a connecting component 3 which are detachably connected in sequence, and a channel for oil smoke to pass through is formed in the flow guide component 2, the telescopic component 1 and the connecting component 3 in an internal communication mode. Wherein, coupling assembling 3 is rigid structure, can set up the subassembly of making an uproar that falls on coupling assembling 3's internal face, and it is better to use experience.

The range hood further comprises a power system 4 arranged in the suspended ceiling and a fume collecting hood 5 arranged near the cooking bench (cooker), wherein the power system 4 is connected to the flow guiding air outlet 22 of the flow guiding component 2 of the range hood pipeline, and the fume collecting hood 5 is connected to the connecting air inlet 32 of the connecting component 3 of the range hood pipeline. The power system 4 includes a volute (not shown), an impeller (not shown), a motor (not shown) and other structures, when the motor drives the impeller to rotate, negative pressure can be generated in the range hood pipeline, and oil smoke (shown by a curve with an arrow in fig. 1) sequentially passes through the smoke collecting air inlet 52 and the smoke collecting air outlet 51 under the action of the negative pressure, and then enters the range hood pipeline. Other structures of the range hood are the same as those of the existing device, and are not repeated here.

The telescopic component 1 is of a flexible structure, and the length of the telescopic component 1 is adjustable along the movement direction of the lampblack. The length of the telescopic component 1 is adjusted according to the height of the suspended ceiling and the position of the cooking bench (cooker), so that the smoke collecting air inlet 52 can be always aligned with the cooking bench (cooker), and the smoke is absorbed more thoroughly. When the interior is refitted or the use place is changed, the length of the telescopic component 1 is correspondingly changed, and the application range is wide.

The oil smoke will gradually cool down in the process of reaching the power system 4, and part of the oil dirt will be condensed out, and the oil dirt will flow down along the pipeline of the range hood. The range hood pipeline is formed by sequentially connecting three parts of mechanisms, and the range hood pipeline is detachably connected with the fume collecting hood 5, so that oil stains are likely to seep out from a connecting gap.

In order to solve the problem, in the flow guiding component 2, the telescopic component 1, the connecting component 3 and the fume collecting hood 5, the air inlet of the device positioned above is penetrated into the air outlet of the device positioned below. The greasy dirt can continuously flow downwards under the action of gravity, can not upwards leak from the junction, has solved the problem of junction oil leak oil spilling. Specifically, as shown in fig. 2 and 3, the air guiding inlet 21 of the air guiding assembly 2 is penetrating through the air telescopic outlet 11 of the telescopic assembly 1; as shown in fig. 2 and 4, the telescopic air inlet 12 of the telescopic assembly 1 is arranged in the connecting air outlet 31 of the connecting assembly 3 in a penetrating manner; as shown in fig. 2 and 5, the connecting air inlet 32 of the connecting assembly 3 is penetrated in the fume collecting air outlet 51 of the fume collecting hood 5.

On the basis of the above structure, as shown in fig. 6, a flow guiding air inlet 21 is formed at the bottom of the flow guiding assembly 2, and a plurality of sinking grooves 61 are formed on the bottom edge of the flow guiding air inlet 21. The sink 61 is a pit-like structure protruding inward, and the top end of the sink 61 is closed, i.e., the flow guide assembly 2 near the sink 61 is a continuous plane as seen from the inside of the flow guide assembly 2.

As shown in fig. 7 and 8, the range hood pipe further includes a connection collar 7, and a collar connection through hole 71 is formed in the connection collar 7. In order to increase the contact area between the ferrule connection through-hole 71 and the connection member to increase the connection strength, it is generally required that the ferrule connection through-hole 71 have a certain depth. The wall thickness of the connection ferrule 7 may be increased, or an internally threaded tube 72 may be provided on the inner side surface of the connection ferrule 7, with the ferrule connection through-hole 71 being partially located in the internally threaded tube 72.

As shown in fig. 9, the connecting hoops 7 are sleeved on the outer ring of the bottom of the diversion assembly 2, the hoops connecting through holes 71 are aligned with the sink slots 61 one by one, and the connecting pieces can enter the sink slots 61 after passing through the hoops connecting through holes 71.

On the basis of the structure, the specific method for realizing the adjustable length of the telescopic assembly 1 is not limited, and the telescopic assembly can be made of flexible materials or designed into a folding structure. In this embodiment, as shown in fig. 10, the length of the middle part of the telescopic assembly 1 is adjustable, and two ends are respectively provided with a fixing frame 13 made of a rigid material. The flow guiding component 2 and the connecting component 3 are respectively connected with the corresponding fixed connecting frame 13, and the connecting structure is stable.

As shown in fig. 6, 10-12, the cross sections of the diversion component 2, the telescopic component 1 and the connecting component 3 are rectangular, so that the installation device is convenient to process, can be installed at the positions of being clung to the plane such as the wall surface, and saves more space. Wherein, the sectional areas of the telescopic component 1 and the connecting component 3 are unchanged all the time; the bottom of the flow guiding component 2 is in a cylinder shape with unchanged cross section area, the top of the flow guiding component 2 is still rectangular, the cross section area is gradually increased, the flow speed of the oil smoke is reduced, the contact area of the oil smoke and a power device such as a motor is increased, and the oil smoke is discharged more thoroughly.

In addition to leakage from the joint gap between the two connecting devices, oil stains may leak from the joint between the connecting piece such as a bolt and the connecting through hole, thereby forming an oil spill phenomenon. Use buckles and inclined screw etc. to keep away oily structure and connect, the connecting piece occupation space is great, has the unstable problem of connection, and buckle and inclined screw etc. warp easily after long-time use, lead to junction leakproofness variation, and oil smoke absorption inefficiency.

In order to solve this problem, it is preferable to provide a sink 61 or the like as shown in fig. 9 at the air inlet of the deflector assembly 2, the telescopic assembly 1 and the connection assembly 3 so that the wall surface at the air inlet is continuous and the oil dirt does not leak out when flowing through.

The end of the connecting piece 9 sequentially passes through the sleeved through hole 8 and the hoop connecting through hole 71 and then enters the sink 61, so that stable connection of the flow guiding component 2 and the telescopic component 1 is realized, good tightness is realized between the flow guiding component 2 and the connecting hoop 7 and between the connecting hoop 7 and the telescopic component 1, no gap exists near the sink 61, and oil stains (shown by curves with arrows in fig. 14) cannot leak/overflow near the sink 61.

The connecting structure between the telescopic component 1 and the connecting component 3 can be the same as the connecting structure between the flow guiding component 2 and the telescopic component 1, or can adopt slightly different structures, and can avoid oil stains from oozing out from gaps of the connecting piece. In this embodiment, as shown in fig. 13 and 15, the telescopic air inlet 12 is provided with a plurality of screw blind holes 62, the screw blind holes 62 extend toward the axis direction of the range hood pipe and have a top surface closed, and the connecting air outlet 31 is provided with a sleeved through hole 8. The screw blind hole 62 has the functions of the countersink 61 (shown in fig. 14) and the hoop connecting through hole 71 (shown in fig. 14), and the end head of the connecting piece 9 passes through the sleeved through hole 8 and then is screwed into the screw blind hole 62, so that the stable connection between the telescopic component 1 and the connecting component 3 can be realized. Grease (shown by the arrow-headed curve in fig. 15) does not bleed out when it passes through the blind screw hole 62.

The connecting structure between the connecting component 3 and the fume collecting hood 5 can be the same as the connecting structure between the flow guiding component 2 and the telescopic component 1, and can also be the same as the connecting structure between the telescopic component 1 and the connecting component 3, so that oil stains can be effectively prevented from seeping out from gaps around the connecting piece. In the present embodiment, in the case of the present embodiment,
