[ detailed description ] embodiments
In order to make the objects, solutions and advantages of the present invention more apparent, the present invention will be further described with reference to the accompanying drawings and preferred embodiments. The individual drawings may not be as precise, in which case the text is referred to.
Example 1
The embodiment of the range hood provided by the invention comprises a shell 1, a fan 2, a plate member 3, a driving device, a guide device and a closable air inlet, and is shown in figures 1 and 2. The range hood is a side-draft range hood, the fan 2 is arranged in the machine shell 1, and the air inlet is formed in the machine shell 1. The fan 2 includes a volute, a motor, and an impeller. The panel member 3 includes a closed position and an open position. When the plate body 3 is in the closed position, the plate body 3 closes the air inlet, as shown in fig. 1, and the oil smoke cannot flow into the range hood. When the plate member 3 is in the open position, the air inlet is open, as shown in fig. 2, and the oil smoke can flow into the range hood through the air inlet. When the plate member 3 is switched from the closed position to the open position, the plate member 3 moves toward the inside of the casing 1.
The drive means, which comprise the airflow actuating member 4 and the transmission member, is used to control the position of the panel member 3. One end of the transmission piece is connected with the airflow actuating piece 4, and the other end is connected with the plate piece 3. The airflow actuator 4 is rotatably fixed in the housing 1. Specifically, the airflow actuator 4 is a plate-like structure, and one end of the airflow actuator 4 is rotatably fixed to the volute of the fan 2, as shown in fig. 1 and 2. The lower surface of the airflow actuator 4 faces downward and the upper surface of the airflow actuator 4 faces upward.
Guide means (not shown in the drawings) for defining the direction of movement of the plate member 3. In particular, guide means for defining the sliding of the plate member 3 in the horizontal direction. The guiding device is provided with a sliding rail. The transmission member is of a rod-like structure, and specifically comprises a transmission rod 5. The transmission rod 5 has one end rotatably connected to the lower surface of the airflow actuator 4 and the other end rotatably connected to the inner surface of the plate member 3. The air flow activation member 4, the transmission rod 5 and the plate member 3 together constitute a slider-crank mechanism, the air flow activation member 4 serving as a crank of the slider-crank mechanism, the transmission rod 5 serving as a connecting rod of the slider-crank mechanism, and the plate member 3 serving as a slider of the slider-crank mechanism. Here, it should be noted that, though, the air flow actuator 4, the transmission rod 5 and the plate member 3 together constitute a slider-crank mechanism; however, in the specific application scenario of the present embodiment, since the volute case restricts the rotation of the airflow actuator 4, the airflow actuator 4 of the present embodiment, which is used as the crank of the crank-slider mechanism, cannot actually rotate 360 degrees.
The airflow actuating piece 4 is arranged to rotate under the action of the pushing force of the airflow generated by the fan 2, so that the driving piece is driven to switch the plate body piece 3 from the closed position to the open position; that is, when the plate member 3 closes the air inlet (as shown in fig. 1), if the fan 2 is operated, the airflow actuator 4 is rotated upward by the pushing force of the airflow generated by the fan 2, the rotated airflow actuator 4 drives the transmission rod 5 to move, and the moving transmission rod 5 drives the plate member 3 to switch from the closed position to the open position (as shown in fig. 2). Arrows in fig. 2 are used to indicate the flow direction of the airflow. When the plate member 3 is switched from the closed position to the open position, the rotational angle of the airflow actuator 4 is less than 90 degrees.
When the airflow actuating member 4 rotates under the pushing force of the airflow generated by the fan 2, the airflow actuating member 4 has a rotational limit position, and when the airflow actuating member 4 is in the rotational limit position, the airflow actuating member 4 is obliquely arranged, as shown in fig. 2. The extreme position of rotation of the airflow actuator 4 is realized by the stop of the volute against the airflow actuator 4. Vividly, when the fan 2 operates, the airflow generated by the fan 2 impacts the lower surface of the airflow actuating part 4, so as to push the airflow actuating part 4 to rotate, and thus the transmission rod 5 is driven to switch the plate body 3 from the closed position to the open position, and as the moving distance of the plate body 3 to the casing 1 increases, the airflow is smoother when flowing through the air inlet, the air volume increases, and the airflow actuating part 4 further rotates upwards until the airflow actuating part 4 reaches the rotating limit position. If the fan 2 is continuously operated, the airflow actuator 4 is maintained at the open position by the urging force of the airflow generated by the fan 2.
The airflow actuating piece 4 is also arranged to be reset to the position shown in fig. 1 under the action of the gravity of the airflow actuating piece 4 when the fan 2 stops running and the pushing force of the airflow disappears, so that the transmission rod 5 is driven to switch the plate body 3 from the opening position to the closing position; that is, when the air inlet is opened (as shown in fig. 2), if the fan 2 stops operating, the driving force of the air flow generated by the fan 2 disappears, the air flow actuator 4 rotates downward under its own gravity to return to the position shown in fig. 1, the rotating air flow actuator 4 drives the transmission rod 5 to move, and the moving transmission rod 5 drives the plate member 3 to switch from the open position to the closed position. After the airflow actuating part 4 is reset under the action of self gravity, the airflow actuating part 4 is horizontally placed, as shown in fig. 1, and at the moment, the airflow actuating part 4 blocks the passage of airflow flowing to the fan 2 to a certain extent.
Specifically, the "rotatable connection" in this embodiment is realized by means of a hinge.
The foregoing is merely a preferred embodiment of the present invention and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the air flow actuator, the transmission rod and the plate element together form a rocker-slider mechanism. As another example, it is also possible to further include a locking device configured to lock the plate member in the open position, specifically, by locking the position of the airflow actuator, the transmission member, or the plate member by the locking device; once the locking device locks the panel member in the open position, the airflow activation member cannot be reset until the locking is released. Specifically, the locking of the locking device may be released to reset the airflow actuator while the fan is stopped. As another example, the extreme rotational position of the airflow actuator can be achieved by setting the extreme inward sliding position of the plate members on the guide. As a further example, the extreme positions of rotation of the airflow actuating member can be achieved by limiting the position of movement of the transmission member. As another example, the solution of this embodiment can also be applied to a top-suction range hood, in which case the plate members are preferably horizontally disposed. For another example, the guide means may be adapted to limit the plate member to slide along the extending direction of the air inlet. For another example, the transmission member may also adopt other possible schemes, as long as the rotation of the airflow actuating member can be converted into the corresponding movement of the plate member, and the scheme of the embodiment is not limited. Furthermore, the plate members do not necessarily have to move in a straight line, and other movement patterns are possible. For another example, after the airflow actuating element is reset, the airflow actuating element can completely block the passage of the airflow flowing to the fan.
Example 2
The invention also provides another range hood embodiment 2, and the range hood embodiment 2 is further improved on the basis of the range hood embodiment 1. The main differences between the hood embodiment 2 and the hood embodiment 1 are as follows.
This smoke ventilator embodiment 2, still include magnet piece 6 that sets up in casing 1. The magnet pieces 6 comprise permanent magnets. The plate member 3 is provided with a member which can be adsorbed by the permanent magnet; for example, the member that can be attracted by the permanent magnet may be an iron member or a permanent magnet, and the like. And a magnet piece 6 for attracting the plate piece 3 toward the inside of the casing 1, as shown in fig. 3 and 4. Arrows in fig. 4 are used to indicate the flow direction of the airflow. It should be noted that, when the plate member 3 is in the closed position, as shown in fig. 3, the fan 2 is not operated and has no driving force of the air flow, and although the magnet member 6 attracts the plate member 3 toward the inside of the casing 1, the attraction force of the magnet member 6 is not sufficient to move the plate member 3 toward the inside of the casing 1. When the plate member 3 is in the open position, as shown in fig. 4, if the fan 2 stops operating and the driving force of the air flow disappears, although the magnet member 6 attracts the plate member 3 toward the inside of the housing 1, the attracting force of the magnet member 6 is not enough to maintain the plate member 3 in the open position, and the air flow actuator 4 is reset to the position shown in fig. 3 by its own gravity, thereby driving the transmission rod 5 to switch the plate member 3 from the open position to the closed position.
For other structures and matching relations of the range hood embodiment 2, please refer to the corresponding description of the range hood embodiment 1.
The foregoing is merely a preferred embodiment of the present invention and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the permanent magnet may be replaced by an electromagnet.
Example 3
The present invention also provides another range hood embodiment 3, and the range hood embodiment 3 is further modified from the range hood embodiment 1. The main differences between the hood embodiment 3 and the hood embodiment 1 are as follows.
When the plate member 3 of this range hood embodiment 3 is switched from the closed position to the open position, the plate member 3 moves toward the outside of the housing 1.
The driving medium of this smoke ventilator embodiment 3 includes the first body of rod 7, the second body of rod 8 and the third body of rod 9 that links up in proper order, as shown in fig. 5 and 6. Arrows in fig. 6 are used to indicate the flow direction of the airflow. The second lever 8 is arranged to rotate around a shaft 10, which shaft 10 is fixed to the housing 1. One end of the first rod 7 is rotatably connected to the lower surface of the airflow actuator 4, and the other end is rotatably connected to the second rod 8. The airflow actuating part 4, the first rod body 7 and the second rod body 8 form a hinge four-bar mechanism together; the airflow actuator 4 and the second rod 8 each serve as a side link of the four-bar hinge mechanism, and the first rod 7 serves as a link of the four-bar hinge mechanism. The second rod 8 is also rotatably connected to the third rod 9, and the first rod 7 and the third rod 9 are respectively connected to the second rod 8 at two sides of the rotating shaft 10. The other end of the third rod 9 is rotatably connected to the plate member 3. The second rod 8, the third rod 9 and the plate 3 together form a rocker-slider mechanism, the second rod 8 acting as a rocker of the rocker-slider mechanism, the third rod 9 acting as a link of the rocker-slider mechanism, and the plate 3 acting as a slider of the rocker-slider mechanism.
For other structures and matching relations of the range hood embodiment 3, please refer to the corresponding description of the range hood embodiment 1.
The foregoing is merely a preferred embodiment of the present invention and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the second rod, the third rod and the plate may form a slider-crank mechanism. For another example, the transmission member may also adopt other possible schemes, as long as the rotation of the airflow actuating member can be converted into the corresponding movement of the plate member, and the scheme of the embodiment is not limited. Furthermore, the plate members do not necessarily have to move in a straight line, and other movement patterns are possible.
Example 4
The invention also provides another embodiment 4 of the range hood, and the embodiment 4 of the range hood is further improved on the basis of the embodiment 3 of the range hood. The main differences between the hood embodiment 4 and the hood embodiment 3 are as follows.
The range hood embodiment 4 further comprises a magnet member 6 disposed within the housing 1. The magnet member 6 includes a permanent magnet. The plate member 3 also includes a permanent magnet. The magnet pieces 6 are adapted to repel the plate pieces 3 toward the outside of the cabinet 1 as shown in fig. 7 and 8 because the permanent magnets of the magnet pieces 6 repel the permanent magnets of the plate pieces 3 (based on the principle that like poles of magnets repel each other). Arrows in fig. 8 are used to indicate the flow direction of the airflow.
It should be noted that, when the plate member 3 is in the closed position, as shown in fig. 7, the fan 2 is not operated and has no airflow pushing force, and although the magnet member 6 repels the plate member 3 toward the outside of the casing 1, the repelling force of the magnet member 6 is not sufficient to move the plate member 3 toward the outside of the casing 1. When the plate member 3 is in the open position, as shown in fig. 8, if the fan 2 stops operating and the driving force of the air flow disappears, although the magnet member 6 repels the plate member 3 toward the outside of the housing 1, the repelling force of the magnet member 6 is not enough to maintain the plate member 3 in the open position, and the air flow actuator 4 will return to the position shown in fig. 7 under the action of its own gravity, thereby driving the transmission member to switch the plate member 3 from the open position to the closed position.
For other structures and matching relations of the range hood embodiment 4, please refer to the corresponding description of the range hood embodiment 3.
The foregoing is merely a preferred embodiment of the present invention and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the permanent magnet may be replaced by an electromagnet.
It should be additionally noted that the present invention should not be construed as limited to the embodiments set forth above, but rather should be construed to cover all possible embodiments defined by the claims set forth below in connection with the disclosure of the specification. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are within the protection scope of the technical solution of the present invention, unless the content of the technical solution of the present invention is departed from.
