It is understood that in other embodiments, the chamber body assembly 10 is not limited to the above-mentioned structure, and may have other structures, which are not specifically limited herein.

The guide plate assembly 18 is installed at the installation opening 14, the guide plate assembly 18 includes an installation portion 20 and a guide panel 22, the guide panel 22 is movably installed at the installation portion 20, the guide panel 22 includes a first panel 28 and a second panel 30 which are rotatably connected with each other, and two sides of one of the first panel 28 and the second panel 30 are respectively connected with a baffle 46. In one embodiment, the baffle assembly 18 includes two baffles 46, and the two baffles 46 are disposed on the surface of the first panel 28 adjacent to the receiving cavity 12 and on the left and right sides of the surface. Under the condition that the diversion panel 22 turns up, the baffle 46 is located in the clearance between the first panel 28 and the second panel 30, and then the space area between the first panel 28 and the second panel 30 can be reduced, thereby reducing the space and bringing negative influence to the smoking effect, and ensuring the smoking effect.

It is understood that in other embodiments, the baffle 46 may be provided on the second panel 30.

In some embodiments, deflector panel 22 is switchable between a first position and a second position; when the diversion panel 22 is located at the first position, the first panel 28 and the second panel 30 are connected to form a flat plate, and the baffle 46 is accommodated in the accommodating cavity 12; with the deflector panel 22 in the second position, the first panel 28 and the second panel 30 are connected in a V-shape, the second position being an up-turned position of the deflector panel 22. So, be convenient for realize the switching between single smoking mouth and the double smoking mouth, satisfy the smoking demand, improve the negative pressure and distribute, promote smoking effect, can guarantee the smoking effect under the different scene demands.

Specifically, referring to fig. 2 and 3, 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, and the adjacent sides of the two panels are connected in a closed manner, the flat 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 smoke absorption effect is not substantially affected. The baffle 46 is received in the receiving cavity 12 to prevent the user from seeing the baffle 46. The first panel 28 may be parallel to the second panel 30 and connected along the same plane. Under the condition that the diversion panel 22 is in the second position, that is, under the condition that the diversion panel 22 is turned outwards, the first panel 28 and the second panel 30 are connected in a V shape, a gap in a triangular area is formed between the first panel 28 and the second panel 30, the gap in the triangular area is communicated with the inside and the outside of the range hood 100, and oil smoke may flow out from the gap in 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, and can shield the internal mechanism.

In some embodiments, the second panel 30 faces the first oil screen 24 when the deflector panel 22 is in the first position. When the diversion panel 22 is located at the second position, the first panel 28 and the second panel 30 are inclined relative to each other, the first panel 28 and the second panel 30 are inclined relative to the mounting portion 20, both of the first panel and the second panel are inclined in a direction away from the accommodating cavity 12, and the first panel and the second panel are connected in a V shape to form an angle with an opening facing the accommodating cavity 12, wherein the angle is not 0 angle or 180 degrees, and may be a right angle, an obtuse angle or an angle with other sizes, which is not limited herein.

In certain embodiments, baffle assembly 18 further comprises an operator panel 23 positioned above deflector panel 22. The operating panel 23 may be connected to the movement mechanism 32 for controlling the movement mechanism 32, so that the deflector panel 22 is switched between the first position and the second position, and switching between single and double smoking ports is possible.

Specifically, referring to fig. 1, the operation panel 23 is located above the diversion panel 22, and the built-in control member is connected to the moving mechanism 32, so that the moving mechanism 32 can be controlled to switch the diversion panel 22 between the first position and the second position.

The range hood 100 mainly includes the following components: the cavity assembly 10, the fan system 16, the deflector assembly 18, the first oil screen 24 and the second oil screen 26; the cavity assembly 10 mainly provides support and fixation for the fan system 16 and provides power part; the fan system 16 is the power part of the whole 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 net 50 can be prevented from being diffused through two sides, the negative pressure at the second oil net 26 is weakened, the smoking effect is weakened, and on the other hand, the baffle can play a role in beautifying and shielding the internal mechanism.

Referring to fig. 8-9, with the deflector panel 22 in the first position, the oil smoke or the airflow in the kitchen can enter the fan system 16 through the first oil net 24 and the second oil net 26 in sequence 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. 9, when the moving mechanism 32 is opened, the guiding panel 22 is switched from the first position to the second position, the oil smoke can enter the fan system 16 through the first oil net 24 and the second oil net 26, and is discharged through 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 part of the lifted oil smoke is sucked into the fan system 16 through the second oil net 26 via 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.
