The blower 32 is fixedly connected with the side wall of the main machine 1, one end of the air guide pipe 33 is fixedly connected and communicated with the blower 32, the other end of the air guide pipe 33 is fixedly connected and communicated with the air guide plate 31 through the fixing support 34 and the hook 35, and therefore the air guide plate 31 is suspended below the main machine 1. As can be seen from fig. 3, in the use state of the range hood, the air guiding pipe 33 is arranged along the vertical direction. Alternatively, the duct 33 may be inclined, or the duct 33 may be bent or bent, as necessary, by those skilled in the art.

As shown in fig. 4 to 7, the air guiding plate 31 includes a first air guiding plate 311 and a second air guiding plate 312 distributed along the thickness direction thereof, and the air guiding plate 31 is provided with a through hole 313, an air inlet 314, an air outlet 315, an air inlet channel 316 and an oil leakage hole 317. Further, the through hole 313 penetrates the air deflector 31 in the thickness direction thereof; the air inlet 314 and the air outlet 315 are both arranged on the first air deflector 311; the air inlet channel 316 is formed between the first air deflector 311 and the second air deflector 312, and the air inlet channel 316 communicates the air inlet 314 with the air outlet 315; the oil leakage hole 317 penetrates the air guide plate 31 and is located above the storage case 2, and the oil leakage hole 317 can allow oil dirt on the upper side of the air guide plate 31 to pass through and thus drip the oil dirt into the storage case 2.

As can be seen, the through-opening 313 is a U-shaped opening, so that a sufficiently large flow capacity is possible while ensuring the drainage effect. Of course, the through hole 313 may be configured as a C-shaped hole or a W-shaped hole as needed by those skilled in the art.

As shown in fig. 4 to 7, a raised portion 3111 is formed on the first air guiding plate 311, the air inlet 314 is formed on the raised portion 3111, a first flange structure 3112 is further formed on the raised portion 3111, and a connector 3113 aligned with and communicated with the air inlet 314 is further disposed on the first air guiding plate 311.

As shown in fig. 6 and 7, the through holes 313 include a first through hole (not shown) formed on the first air deflection plate 311 and a second through hole (not shown) formed on the second air deflection plate 312. The first through hole is surrounded by the first flange structure 3112, or the first through hole is surrounded by a portion of the first flange structure 3112. The second through hole is surrounded by the second cuff structure 3121 or the second through hole is surrounded by a portion of the second cuff structure 3121.

With reference to fig. 6 and 7, in a state that the air deflector 31 is installed, the second flange structure 3112 is embedded into the first flange structure 3112, and an annular gap is formed between the first flange structure 3112 and the second flange structure 3112, which is the air outlet 315. As can be understood by referring to fig. 7, the extending direction of the air outlet 315 is inclined upward, so that the air flow can be blown upward by the air outlet 315. Further, the other regions of the first air guiding plate 311 except for the raised portion 3111 are bonded to the second air guiding plate 312. A certain distance exists between the protruding portion 3111 and the second wind deflector 312, and thus the first wind deflector 311 and the second wind deflector 312 surround the wind inlet passage 316 together at the protruding portion 3111.

As shown in fig. 1 and 4 to 6, the oil leakage hole 317 penetrates both the first air guiding plate 311 and the second air guiding plate 312, and the oil leakage hole 317 is located at the rear portion of the air guiding plate 31.

Illustratively, a plurality of threaded holes are respectively formed in the first air deflector 311 and the second air deflector 312, and the threaded holes in the first air deflector 311 are aligned with the threaded holes in the second air deflector 312 one by one. The hook 35 includes a base (not shown) having a through hole and a rod (not shown) fixedly connected to or integrally formed with the base. The screw is screwed into the screw hole of the air deflector 311 after passing through the through hole of the holder body, and thus the hook 35 and the air deflector 31 are fixedly connected together.

As shown in fig. 3, two ends of the fixing bracket 34 are respectively provided with a locking groove (not marked in the figure). In the installed state, the rod body of the hook 35 is inserted into the slot, so as to fixedly connect the fixing bracket 34 and the air deflector 31 together.

In the installed state, one end of the air guiding pipe 33 is inserted into the installation cavity, and therefore the air guiding pipe 33 is fixedly connected with the fixing bracket 34, and the air guiding pipe 33 is communicated with the air inlet 314. Further, the joint 3113 is also inserted into the mounting cavity, so that the joint 3113 abuts against the air guide duct 33. Preferably, the connection 3113 is hermetically connected to the air duct 33 to prevent air leakage. As an example, a sealing ring is provided at an end of the joint 3113 or the air guide duct 33, and in an installed state, the joint 3113 and the air guide duct 33 are abutted together by the sealing ring, thereby achieving a sealed connection. As a second example, the joint 3113 and the air guide pipe 33 are respectively abutted to a side wall of the installation cavity of the fixing bracket 34 through a sealing ring, so that the joint 3113 and the fixing bracket 34, and the air guide pipe 33 and the fixing bracket 34 are hermetically connected together, and thus the joint 3113 and the air guide pipe 33 are hermetically connected.

As shown in fig. 1 to 6, the air deflector 31 is symmetrically provided with a U-shaped through hole 313, two air inlets 314, an annular air outlet 315 which surrounds the through hole 313, and an air inlet channel 316. Of course, the skilled person can also arrange the through holes 313, the air inlets 314, the air outlets 315 and the air inlet channels 316 in any other feasible number, such as three, four, five, etc., as required. Further, each air inlet 314 is provided with an air guiding pipe 33 and a blower 32.

As shown in fig. 1, the through hole 313 and the air outlet 315 are aligned with the smoking port 11 of the main unit 1, so that the oil smoke passing through the through hole 313 and the air flow emitted from the air outlet 315 can be directly emitted to the smoking port 11, and thus can be transferred to the outside of the room by the fan in the main unit 1.

The operation of the smoke guide device 3 in the present embodiment will be briefly described with reference to fig. 1, 3, 6 and 7.

When the range hood works, the blower 32 delivers air into the air guide pipe 33, and the air flowing in the air guide pipe 33 forms airflow and enters the air inlet channel 316 through the air inlet 314, and then is emitted to the smoke suction port 11 of the range hood through the air outlet 315. In the process of the airflow emitted from the air outlet 315 to the smoke suction port 11 of the range hood, due to the bernoulli principle, the oil smoke below the through hole 313 is forced to flow into the through hole 313 and emitted to the smoke suction port 11 along with the airflow emitted from the air outlet 315. This process is similar to the operation of a bladeless fan.

Based on the foregoing description, it can be understood by those skilled in the art that the oil smoke guiding device 3 of the present embodiment can guide the oil smoke to the smoke suction port 11, so as to improve the smoking capability of the range hood.

Although not shown, in other embodiments of the present disclosure, one skilled in the art may omit the air duct 33 to fixedly connect the blower 32 with the fixing bracket 34 and thus communicate with the air inlet 314, if necessary. Further, the fixing bracket 34 and the hook 35 can be omitted by those skilled in the art as required, so that the blower 32 is directly and fixedly connected with the air deflector 31 and communicated with the air inlet 314.

So far, the technical solutions of the present disclosure have been described in connection with the foregoing embodiments, but it is easily understood by those skilled in the art that the scope of the present disclosure is not limited to only these specific embodiments. The technical solutions in the above embodiments can be split and combined, and equivalent changes or substitutions can be made on related technical features by those skilled in the art without departing from the technical principles of the present disclosure, and any changes, equivalents, improvements, and the like made within the technical concept and/or technical principles of the present disclosure will fall within the protection scope of the present disclosure.
