When the diversion panel 22 is in the first position, the first panel 28 and the second panel 30 are connected to form a flat plate, the baffle 46 is accommodated in the accommodating cavity 12, when the diversion panel 22 is in the second position, the first panel 28 and the second panel 30 are connected to form a V-shape, and the baffle 46 is located in a space between the first panel 28 and the second panel 30. Like this, under the circumstances that diversion panel 22 is located the second position, baffle 46 is located the clearance between first panel 28 and the second panel 30, and then the space area between reducible first panel 28 and the second panel 30 to reduce this space and can bring negative effects to the smoking effect, guarantee the smoking effect.

Specifically, referring to fig. 3, the baffle plate assembly 18 includes two baffle plates 46, the two baffle plates 46 are respectively disposed on the surface of the first panel 28 close to the accommodating cavity 12 and located on the left and right sides of the surface, and since the baffle plates 46 are fixedly connected to the first panel 28, the baffle plates 46 move along with the movement of the first panel 28 in the process of switching the flow guide panel 22 from the first position to the second position.

When the diversion panel 22 is at the first position, the first panel 28 and the second panel 30 are connected to form a flat plate, the flat plate diversion panel 22 can be attached to the edge of the installation part 20, the interval between the diversion panel 22 and the edge of the installation part 20 is small, and the smoking effect is basically not affected. The baffle 46 is received in the receiving cavity 12 to prevent the user from seeing the baffle 46.

Under the condition that the diversion panel 22 is in the second position, the first panel 28 and the second panel 30 are connected to form a V-shape, a gap which is a triangular area is formed between the first panel 28 and the second panel 30, the gap of the triangular area is communicated with the inside and the outside of the range hood 100, and the oil smoke can flow out from the gap of the triangular area to influence the smoking effect. By providing the baffle 46 in this gap, on the one hand, the negative pressure at the inner oil screen 50 inside the second oil screen 26 can be prevented from diffusing through both sides, the negative pressure at the second oil screen 26 can be weakened, and the smoking effect can be weakened, and on the other hand, the baffle can play a role in beauty to shield the internal mechanism.

In certain embodiments, the baffle 46 is coupled to the first panel 28 and is capable of moving with the movement of the first panel 28. Thus, an additional mechanism for driving the shutter 46 is not required, and cost reduction and a simplified structure can be achieved.

Specifically, the moving mechanism 32 is configured to drive the first panel 28 to move, and when the first panel 28 moves, the baffle 46 can be driven to move, so that when the diversion panel 22 is switched between positions, the baffle 46 also moves synchronously with the movement of the diversion panel 22, and thus, an additional mechanism for driving the baffle 46 does not need to be added, which can reduce cost and simplify structure.

The range hood 100 mainly includes the following components: the air conditioner comprises a cavity assembly 10, a fan system 16, a flow guide plate assembly 18, a first oil net 24 and a second oil net 26; the cavity assembly 10 mainly provides support and fixation for the fan system 16 and provides a power part; the fan system 16 is the power part of the entire range hood 100.

The main technical scheme of the utility model can comprise;

1. single suction changes double suction wind channel: when the diversion panel 22 is located at the first position, the second oil net 26 can be used as a single oil net, which can meet the use scene of the low air volume demand of the user or purify the air inside the kitchen through the net, thereby playing the role of an air manager. When a large air volume or a high-height pot is needed, the flow guide panel 22 is switched to the second position, the second oil net 26 moves upwards and turns outwards, the oil smoke which is not lifted and diffused is quickly sucked away through the first oil net 24 at the lower part, the remaining lifted and diffused oil smoke is sucked away through the second oil net 26 which turns outwards, and the smoking effect can be greatly improved through double suction.

2. Everting sliding oil net movement mechanism 32: the connecting rod assembly 36 and the synchronizing member 40 are used for providing synchronism and driving force and rotation of the whole mechanism, and the lower part is a roller 44 which can ensure that the oil net moves up and down stably.

3. The baffle 46 is fixed on the first panel 28, on one hand, the negative pressure at the inner oil screen 50 can be prevented from diffusing through two sides, the negative pressure at the second oil screen 26 can be weakened, the smoking effect can be weakened, and on the other hand, the baffle can play a role in beautifying and shielding the internal mechanism.

Referring to fig. 7-8, with the deflector panel 22 in the first position, the oil smoke or air flow in the kitchen, in turn, can enter the fan system 16 through the first oil mesh 24 and the second oil mesh 26 and be removed by the fan system 16. The scene that this kind of operating mode used is that the oil smoke is less on the one hand, and on the other hand can regard as the air intake of air butler, will purify the inside air of kitchen regularly, makes it keep circulating. As shown in fig. 8, when the moving mechanism 32 is turned on, the guiding panel 22 is switched from the first position to the second position, and the oil smoke can enter the fan system 16 through the first oil net 24 and the second oil net 26 and be exhausted by the fan system 16, wherein the first oil net 24 is closer to the pan, the negative pressure moves downwards, the oil smoke is directly sucked into the fan system 16 after being fried, and the remaining oil smoke with the raised lower part is sucked into the fan system 16 through the second oil net 26 and the inner oil net 50. After the movement mechanism 32 is opened, wide-angle negative pressure is formed, and the smoking effect can be greatly improved through the air inlet layout of top side double suction. In addition, because the smoking mouth moves upwards, the problem that the traditional open-close plate structure bumps the pot can be avoided.
