To make the objects, solutions and advantages of the present application more clear, the present application is further described below with reference to the accompanying drawings and preferred embodiments.
The embodiment of the range hood provided by the application comprises a smoke collecting hood 13, a fan, a casing 14, an oil collecting device 4, a driving device, a fixed smoke guide plate 2 and a movable smoke guide plate 1, and as shown in fig. 1 to 4, the range hood is a top suction type range hood. The fan is disposed within the housing 14. The fume collecting hood 13 is provided with an air inlet, and a filter screen 5 is arranged at the air inlet of the fume collecting hood 13. The fixed smoke guide 2 is fixed to the filter screen 5 as shown in fig. 3 and 4. The fixed smoke guide plate 2 and the movable smoke guide plate 1 are both made of stainless steel plates.
The fixed smoke guide plate 2 adopts a non-porous structure. The fixed smoke guide 2 is inclined downward from its middle toward its edge as shown in fig. 1 to 4. The upper surface of the fixed smoke guide plate 2 is in a quadrangular frustum pyramid shape. By "fixing the upper surface of the smoke guide 2", it is understood that: the surface of the smoke guide plate 2 facing the filter screen 5 is fixed. It should be noted here that, in the normal use state of the range hood, the fixed smoke guide plate 2 is fixed; however, in the present embodiment, the fixed smoke guide 2 is detachable for cleaning, and "fixed" does not mean non-detachable. In the case of the present embodiment, the edge of the fixed smoke guide 2 is rectangular as a whole, as shown in fig. 4.
The movable smoke guide plate 1 is provided with an air inlet through hole 3, and the air inlet through hole 3 is the only through hole of the smoke guide plate. The air inlet hole 3 is square, and the air inlet hole 3 is arranged at the central position of the movable smoke guide plate 1. The air inlet through hole 3 of the movable smoke guide plate 1 is positioned below the air inlet of the smoke collecting cover 13. The movable smoke guide plate 1 is in a funnel shape converging towards the air inlet through hole 3, and as shown in fig. 1, 2, 3, 5 and 6, grease attached to the movable smoke guide plate 1 flows towards the edge of the air inlet through hole 3 under the action of gravity. It should be particularly emphasized here that the air inlet through hole 3 provided in the movable smoke guide plate 1 is a smoke channel dedicated to air inlet, and cannot be identical to an oil leakage hole dedicated to guiding grease flow of a deflector body of a conventional range hood.
The driving means is arranged to be adapted to drive the movable smoke guide 1 into an up-and-down movement for switching between the first position and the second position. The movable smoke guide plate 1 descends when switching from the first position to the second position, and the movable smoke guide plate 1 ascends when switching from the second position to the first position. When the movable smoke guide plate 1 is at the first position, the fixed smoke guide plate 2 blocks the air inlet through hole 3, as shown in fig. 1, at this time, the edge of the fixed smoke guide plate 2 abuts against the inner wall of the movable smoke guide plate 1. When the movable smoke deflector 1 is at the second position, the air inlet hole 3 is open, as shown in fig. 2, and at this time, a certain distance is formed between the edge of the fixed smoke deflector 2 and the inner wall of the movable smoke deflector 1.
When the movable smoke guide 1 is in the second position, the periphery 15 of the movable smoke guide 1 is spaced from the smoke collecting hood 13 to form an airflow inlet, as shown in fig. 2. By "the periphery 15 of the movable smoke guide 1", it is understood that: the top edge of the funnel-like structure. In the present embodiment, the periphery 15 of the movable smoke guide 1 is rectangular. When the movable smoke guide plate 1 is at the second position, if the fan runs, the airflow flows in from the airflow inlet and the air inlet through hole 3, then flows through the filter screen 5, then flows into the casing 14, and then is discharged into the common flue through the exhaust pipe.
When the movable smoke guide plate 1 is at the first position, the airflow inlet is closed. Specifically, when the movable smoke guide 1 is in the first position, the periphery 15 of the movable smoke guide 1 abuts against the smoke collecting hood 13, and thus the above-described airflow inlet is closed, as shown in fig. 1. Because, when the movable smoke guide plate 1 is at the first position, the fixed smoke guide plate 2 blocks the air inlet through hole 3; therefore, when the movable smoke guide 1 is at the first position, all the airflow channels for supplying air to flow into the range hood are closed.
And the oil collecting device 4 is arranged at the edge of the air inlet through hole 3 to contain the grease dropping from the edge. The edge of the air inlet hole 3 is provided with two supporting convex edges 7 which are arranged oppositely, and the oil collecting device 4 is provided with two hooks 8, as shown in fig. 3 and 6. The two hooks 8 correspond to the two supporting convex edges 7 one by one, and the two hooks 8 are respectively hung on the corresponding supporting convex edges 7, so that the oil collecting device 4 is fixed at the edge of the air inlet through hole 3, as shown in fig. 1, 2 and 5. Specifically, the oil collector 4 is an annular groove adapted to the edge of the air inlet hole 3, and the overall shape of the annular groove is substantially the same as the shape of the edge of the air inlet hole 3, so that the grease dropping from the edge of the air inlet hole 3 falls into the annular groove, thereby completing the collection of the grease. Specifically, the air inlet through hole 3 is square, and the whole annular groove is also square. When the movable smoke guide plate 1 is at the second position, if the fan runs, the airflow flows through the hollow area of the annular groove and then flows into the air inlet through hole 3.
The drive means comprise two motors and two telescopic rods 6. The two motors correspond to the two telescopic rods 6 one by one. Every motor all is provided with the gear, and every telescopic link 6 then all is provided with the rack. The gear of the motor is meshed with the corresponding rack of the telescopic rod 6. The two motors run synchronously to drive the two telescopic rods 6 to lift synchronously, thereby driving the movable smoke guide plate 1 to lift.
The two telescopic rods 6 are respectively positioned at the left side and the right side of the air inlet of the fume collecting hood 13. The movable smoke guide plate 1 is detachably fixed at the bottom ends of the two telescopic rods 6. The bottom of any telescopic rod 6 is provided with a supporting rod, one end of the supporting rod is provided with a hook body 9, and the other end of the supporting rod is provided with a buckle 10. The movable smoke guide plate 1 is provided with a first connecting piece 11 matched with the hook body 9 and a second connecting piece 12 matched with the buckle 10. When the movable smoke guide plate 1 is fixed at the bottom end of the telescopic rod 6, the first connecting piece 11 is firstly placed on the hook body 9, then the movable smoke guide plate 1 is rotated around the first connecting piece 11 serving as an axis until the second connecting piece 12 is clamped into the buckle 10, and therefore the movable smoke guide plate 1 is fixed at the bottom end of the telescopic rod 6. When the movable smoke guide plate 1 is detached from the bottom end of the telescopic rod 6, the second connecting piece 12 is pressed from the outside to the inside, and the second connecting piece 12 can be separated from the buckle 10.
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 hole may be circular. Correspondingly, the oil collecting device is a circular groove which is matched with the edge of the air inlet through hole. Of course, the air inlet hole may have other possible shapes, and is not limited to the above. For example, when the movable smoke guide is in the first position, the airflow inlet formed by the periphery of the movable smoke guide and the smoke collecting hood may be smaller (than when the movable smoke guide is in the second position). At this time, if the blower is operated, the air flow flows in from the air flow inlet, passes through the filter screen, then flows into the casing, and then is discharged into the common flue through the exhaust pipe. For example, the oil collector may be integrally formed with the movable smoke guide. For example, the upper surface of the fixed smoke guide plate may be in a truncated cone shape. For another example, the oil collecting device may be fixed to the edge of the air inlet through hole by a fastening method, which is not limited to the above method, and other possible fixing methods may also be used, for example, the oil collecting device may be fixed to the edge of the air inlet through hole by a fastening method. For another example, the fixing manner between the movable smoke guide plate and the bottom end of the telescopic rod is not limited to the above, and other possible fixing manners may be adopted, for example, the matching structure between the second connecting member and the buckle may be replaced by a magnet attracting matching manner. 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 to directly drive the telescopic rod.
This application still provides a lead cigarette board embodiment for smoke ventilator, should lead the cigarette board and be provided with an air inlet through hole, and this air inlet through hole is the only through-hole of this smoke deflector. Under the user state (under the state that the smoke ventilator was applied to in the installation promptly), this smoke deflector is towards the hourglass hopper-shaped that the air inlet through-hole assembled. In fact, when the smoke guide embodiment is applied to the range hood embodiment, the smoke guide embodiment is the movable smoke guide 1 of the range hood embodiment.
