According to the circumstances, the air-out device can also be: the interval sets up in the lower air outlet 3 of guide plate 2 downside or the interval sets up in the side air outlet 4 on both sides about guide plate 2 surface. The shapes of the lower air outlet 3 and the side air outlet 4 can be any one of circular, oval, rectangular, kidney-shaped hole or fan-shaped. The air outlet is divided into directional air outlets according to whether the direction of the air flow discharged from the side air outlet can be changed, and as shown in fig. 3, the direction of the air flow discharged from the optimal side air outlet 4 is vertical to the surface of the guide plate 2. And the diversion air outlet in addition, as shown in fig. 4, 5, the diversion air outlet includes: a series of partition plates 5 forming the partition side air outlets 4, the inner side edges of the partition plates 5 are respectively hinged with a rotating shaft (not shown in the figure). A driving rod 6 and a driving device for driving the driving rod 6 to move up and down are transversely arranged in the inner cavity of the guide plate 2, and two end parts of the driving rod 6 are respectively hinged with free ends of the partition plates 5 on one side through a connecting rod mechanism (not shown in the figure). The driving device can adopt some conventional transmission mechanisms, for example, a motor drives the driving rod 6 to move up and down through a gear 7 and a rack 8 transmission mechanism, and then the connecting rod mechanism drives each partition plate 5 to rotate around a rotating shaft on the inner side of the partition plate. When the air-conditioning device is used, the motor can be kept on according to requirements, so that the partition plate 5 swings up and down, and the direction of discharged air flow changes up and down. The motor can also be stopped when the partition plate 5 is at a certain required angle. As shown in fig. 6, the partition 5 stops swinging when it is perpendicular to the plane of the deflector 2, so that the direction of the exhaust air flow is perpendicular to the plane of the deflector 2 and does not change.
referring ~ fig. fig. 1 ~ fig. 4, the flow guide plate 2 of the side-draft range hood of the present invention is provided with an air supply device communicating with the outside, the air supply device includes a smoke guide fan 10 and an air guide pipe 9, the air guide pipe 9 is provided on the surface of the flow guide plate 2, and communicates the inner cavity of the flow guide plate 2 with the smoke guide fan 10. the smoke guide fan 10 can be disposed on the air inlet 11 of the two side plates 03 of the side-draft range hood or on the air inlet of the top plate 02 of the side-draft range hood as required, as shown in fig. 2, the air supply device is configured ~ fig. blow air into the inner cavity of the flow guide plate 2, and then the air flow is discharged through the air outlet device of the flow guide plate 2, so as ~ fig. form an air curtain or an elastic pipe covering around the furnace platform and covering a part of the area where oil smoke is generated, and the cage of the oil smoke generated by cooking in the furnace platform is firmly covered in the area composed of the air curtain and the side plates of the range hood.
When the side-suction range hood provided by the utility model does not work, the smoke guide plate 04 is closed (as shown in figure 1); when the range hood works, the smoke guide plate 04 is opened (as shown in fig. 2). As shown in fig. 2, during operation, the smoke guide plate 04 can be opened to the maximum position, the smoke guide fan 10 is opened to blow air into the flow guide plate 2, the air flow is blown out downwards from the lower air outlet 3 on the lower side of the flow guide plate 2 and is perpendicular to the flow guide plate 2 from the side air outlets 4 on the two sides of the flow guide plate 2, so that an air curtain covering around the stove is formed, and the lampblack gas generated by cooking on the stove is firmly covered in the area formed by the air curtain and the side plate of the range hood. The smoke guide plate 04 can generate a good smoke guide isolation effect, so that the oil smoke forms a barrier with the outside, and the oil smoke is prevented from escaping from the front and the two side faces. The separated oil smoke is exhausted through a discharge flue under the suction action of the smoke exhaust fan component 01. According to the requirement, the motor can be kept to be started, so that the partition plate 5 swings up and down, the direction of the exhausted airflow changes up and down, and the state of sweeping and cutting the airflow up and down is formed, so that the oil smoke protection device is suitable for different oil smoke protection occasions.
