The front side plate 13, the right side plate 16, the rear side plate 14 and the left side plate 15 are connected in this order in the circumferential direction. The outer surface of the junction of the front side panel 13 and the right side panel 16 is smoothly transitioned. The outer surface of the junction of the right side panel 16 and the rear side panel 14 transitions smoothly. The outer surface of the junction of the rear side panel 14 and the left side panel 15 is smoothly transitioned. The outer surface of the joint of the left side plate 15 and the front side plate 13 is smoothly transited. The front side plate 13, the left side plate 15 and the right side plate 16 are all non-porous plates. The rear side plate 14 is provided with a triangular air inlet 19, the bottom edge of the air inlet 19 is parallel to the extending direction of the connecting part 17, and the bottom edge of the air inlet 19 is positioned above the opening of the oil cup 2. This triangle-shaped air intake 19 has matchd the molding of guide plate 1 well, helps promoting smoke ventilator's air inlet effect. As shown in fig. 5, three corners of the triangular air inlet 19 are rounded corners, the triangle is an isosceles triangle, and the "bottom side of the air inlet 19" refers to the bottom side of the isosceles triangle. The engagement portion 17 is located at the top ridge of the shingle roof-like outer surface 12, as shown in fig. 4. The upper edge of the guide plate 1 is provided with a circle of vertical upward flanges 100.
As shown in fig. 1 to 3, in the use state, the tile roof-shaped outer surface 12 of the deflector 1 is disposed downward, and the front side plate 13, the rear side plate 14, the left side plate 15 and the right side plate 16 are all inclined and gathered toward the joining portion 17, that is, the front side plate 13, the rear side plate 14, the left side plate 15 and the right side plate 16 are all inclined toward the joining portion 17, and the front side plate 13, the rear side plate 14, the left side plate 15 and the right side plate 16 are all gathered toward the joining portion 17; the triangular air inlet 19 of the rear side plate 14 is shielded by the front side plate 13 in the horizontal direction; the top ends of the vertical upward flanges 100 at the upper edge of the guide plate 1 are positioned on the same horizontal plane; the included angle between the outer surface of the front side plate 13 and the horizontal plane is equal to the included angle between the outer surface of the rear side plate 14 and the horizontal plane, and the included angles are acute angles; the included angle between the outer surface of the left side plate 15 and the horizontal plane is equal to the included angle between the outer surface of the right side plate 16 and the horizontal plane, and the included angles are acute angles.
The oil cup 2 is suspended from the joint 17 as shown in fig. 1 to 3. The oil cup 2 is in a strip shape, and the extending direction of the oil cup is parallel to the extending direction of the connecting part 17. The engagement portion 17 is provided with an oil leak hole 18 as shown in fig. 5. In the use state, the oil leakage hole 18 is positioned above the opening of the oil cup 2 and is used for guiding the grease on the inner surface 11 of the guide plate 1 into the oil cup 2.
The outer surface of the filter screen 3 is in the shape of a roof tile protruding towards the inner surface 11 of the baffle 1, as shown in fig. 4. The filter screen 3 is provided with a non-porous plate portion 31 and a smoke intake portion. The smoke inlet portion is provided with a plurality of elongated smoke inlet holes 32, as shown in fig. 6. In the use state shown in fig. 1 to 3, the imperforate plate portion 31 and the rear side plate 14 are parallel to each other.
The driving device comprises a motor, a rack and four lifting slide rails 4. Guide plate 1 detachably is fixed in the bottom of four lift slide rails 4. The motor is provided with a gear, and the gear of the motor is meshed with the rack. The motor runs to drive the rack to lift, the rack drives the four lifting slide rails 4 to lift synchronously, and the guide plate 1 lifts along with the four lifting slide rails 4.
The driving device is arranged to be suitable for driving the guide plate 1 to move up and down so as to switch between a first position and a second position. When the air deflector 1 is switched from the first position to the second position, the air deflector 1 rises. When the air deflector 1 is switched from the second position to the first position, the air deflector 1 descends. When the guide plate 1 is at the first position, an air inlet gap is formed between the guide plate 1 and the smoke collection cavity 5 at intervals, as shown in fig. 2 and 3, at this time, if the fan operates, the airflow flows in from the air inlet 19 and the air inlet gap respectively, then flows through the filter screen 3, then flows into the casing 6, and then is discharged into the common flue through the exhaust pipe. When the guide plate 1 is in the second position, the guide plate 1 abuts against the smoke collection cavity 5, the air inlet gap is closed, and the air inlet 19 of the rear side plate 14 is completely blocked by the non-porous plate part 31 of the filter screen 3, as shown in fig. 1. The imperforate plate portion 31 of the filter screen 3 is also triangular and sized to match the triangular air inlet 19, so that the imperforate plate portion 31 just blocks the air inlet 19 when the baffle 1 is in the second position.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the air inlet gap may be formed between the air deflector and the smoke collection chamber when the air deflector is in the second position, but the air inlet gap is reduced compared to the air inlet gap when the air deflector is in the first position. For another example, when the guide plate is in the second position, the air inlet of the rear side plate is partially blocked by the non-porous plate part of the filter screen. For another example, the driving device is not limited to the above embodiment, and other driving schemes capable of achieving the lifting movement may be adopted, for example, the driving device may also adopt a linear motor.
The elements of the different embodiments may be combined with each other in any feasible manner to achieve the object of the application.
