A filter screen assembly 100 of an air conditioner indoor unit according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1 to 12, a filter screen assembly 100 of an air conditioner indoor unit according to an embodiment of the present invention may include: the filter screen support 10, the first filter screen 20, the second filter screen 21, the reset element 30, the elastic element 40 and the position detector 50.
Specifically, the filter screen bracket 10 is provided with an air port 101; the first filter screen 20 and the second filter screen 21 are arranged on the filter screen support 10, the first filter screen 20 and the second filter screen 21 are provided with a covering position for covering the air port 101 and an opening position for opening the air port 101, and are movable between the covering position and the opening position, as shown in fig. 1, the lower end of the filter screen support 10 is the opening position as shown by an arrow, the upper end of the filter screen support 10 is the covering position, and the first filter screen 20 and the second filter screen 21 move from the lower end to the upper end in the direction as shown by the arrow, namely, the movement from the opening position to the covering position is realized. The reset element 30 is disposed on the filter screen support 10 and is movable between a first position and a second position, when the reset element 30 is disposed at the first position, the reset element 30 limits the second filter screen 21 to move toward the covering position, and when the reset element 30 is disposed at the second position, the reset element 30 releases the limit on the second filter screen 21, and the second filter screen 21 can move from the open position toward the covering position.
The elastic member 40 is connected with the reset member 30, and the elastic member 40 drives the reset member 30 to be located at the first position, and when the first filter screen 20 moves towards the covering position, the elastic member can be stopped against the reset member 30, so that the reset member 30 moves from the first position to the second position. The position detector 50 is provided on the screen holder 10, and the position detector 50 is operated when the second screen 21 is in the closing position, so as to realize in-place detection.
Therefore, when the first filter screen 20 and the second filter screen 21 are in the opening position for opening the tuyere 101, the reset piece 30 can be in the first position under the drive of the elastic piece 40, when the first filter screen 20 and the second filter screen 21 move from the opening position to the covering position, if the second filter screen 21 reaches the reset piece 30 before the first filter screen 20, the second filter screen 21 stops moving to the covering position due to the limiting effect of the reset piece 30, the first filter screen 20 continues to move to the covering position, when the first filter screen 20 also reaches the reset piece 30, the first filter screen 20 is abutted against the reset piece 30, so that the reset piece 30 moves from the first position to the second position, at the moment, the reset piece 30 loses the limiting effect on the second filter screen 21, the second filter screen 21 continues to move to the covering position, and finally the first filter screen 20 and the second filter screen 21 simultaneously reach the covering position, and the second filter screen 21 triggers the position detector 50 to realize in-place detection; if the first filter screen 20 reaches the reset piece 30 before the second filter screen 21, the first filter screen 20 is stopped against the reset piece 30, so that the reset piece 30 moves from the first position to the second position, then the second filter screen 21 reaches the reset piece 30, and the second filter screen 21 directly moves to the covering position through the reset piece 30, the first filter screen 20 reaches the covering position after passing through the reset piece 30, the movement is stopped, then the second filter screen 21 reaches the covering position, and the second filter screen 21 triggers the position detector 50 to realize in-place detection.
According to the filter screen assembly 100 of the air conditioner indoor unit provided by the embodiment of the invention, the reset piece 30 is arranged so that the position detectors 50 are triggered when all the first filter screen 20 and the second filter screen 21 are in place, so that the in-place detection is realized, and the filter screen assembly 100 of the air conditioner indoor unit provided by the embodiment of the invention can realize the in-place detection by only one position detector 50, is simpler in structure, saves installation space and saves production cost, unlike the in-place condition that two position detectors are required to detect two filter screens respectively in the related art.
According to some embodiments of the present invention, as shown in fig. 5, the reset element 30 may include: a connection portion 31, a mating portion 32, and a stopper portion 33. The connection part 31 is connected to the screen supporter 10, and the connection part 31 is connected to the elastic member 40. The fitting portion 32 is connected to the connecting portion 31, and the fitting portion 32 may be stopped against the first filter screen 20. The stop portion 33 is connected to the connection portion 31, and the stop portion 33 may stop the second filter 21 when the reset element 30 is located at the first position. Therefore, the reset piece 30 can respectively act with the first filter screen 20 and the second filter screen 21 through different parts, and the structural design is more reasonable.
Further, as shown in fig. 5, the engaging portion 32 may have a guiding inclined surface 321, where the guiding inclined surface 321 extends obliquely upward with respect to the vertical direction and toward the direction of the covering position, the guiding inclined surface 321 may abut against the end surface of the first filter screen 20, when the first filter screen 20 reaches the reset element 30, the guiding inclined surface 321 abuts against the first filter screen 20, and during the advancing process of the first filter screen 20, the engaging portion 32 may gradually and naturally move downward, so as to realize that the reset element 30 moves from the first position to the second position, and the moving performance is good.
Still further, the engaging portion 32 may have a guiding plane 322, where the guiding plane 322 abuts against the bottom surface of the first filter 20, and the guiding plane 322 is connected to an end of the guiding inclined plane 321 adjacent to the covering position. Therefore, when the upper end of the first filter screen 20 passes through the guiding inclined plane 321 and then can continue to move through the guiding plane 322, in the moving process, the bottom surface of the first filter screen 20 can be stopped on the guiding plane 322, at this time, the guiding plane 322 can guide and support the first filter screen 20, the matching area of the guiding plane 322 and the first filter screen 20 is larger, the matching part 32 can be stably positioned at the lower part of the first filter screen 20, the resetting piece 30 can be stably positioned at the second position, and the passing of the second filter screen 21 is facilitated.
Referring to the embodiment shown in fig. 5 to 12, the stop portion 33 may be located at one side of the guiding plane 322 and located at one side of the guiding inclined plane 321 adjacent to the covering position, so that the matching portion 32 and the stop portion 33 are more matched with the positions of the first filter screen 20 and the second filter screen 21, and it is ensured that the stop portion 33 releases the restriction on the second filter screen 21 when the first filter screen 20 reaches the guiding plane 322, and it is better ensured that the first filter screen 20 and the second filter screen 21 simultaneously continue to move through the reset member 30.
According to some embodiments of the present invention, as shown in fig. 3 and 5, the fitting portion 32 may be formed as an elongated block extending in the moving direction of the first filter screen 20, and the stopper portion 33 may be formed as a stopper block vertically connected to one side surface of the fitting portion 32. When the first filter screen 20 and the second filter screen 21 repeatedly act on the matching portion 32 and the stop portion 33, respectively, a certain impact effect is inevitably exerted on the matching portion 32 and the stop portion 33, and the above structure increases the connection area, thickness and strength of the matching portion 32 and the stop portion 33 and the connection portion 31, so that the service life of the resetting member 30 is longer.
Alternatively, as shown in fig. 3 and 4, the elastic member 40 may be a torsion spring, and the reset member 30 may pivot between a first position and a second position, as shown in fig. 7 to 12, when the force of the first filter 20 is not applied, the torsion spring drives the reset member 30 to be in the first position, when the force of the first filter 20 is applied, the reset member 30 is pressed to the torsion spring to move toward the second position, and when the first filter 20 moves from the covering position to the opening position, the torsion spring may drive the reset member 30 to restore from the second position to the first position. The torsion spring is small in size, large in torsion and high in recycling times, so that the filter screen assembly 100 is simpler in structure, small in assembly size and long in service life, and the reset piece 30 can well pivot between the first position and the second position. Of course, the elastic member 40 is not limited to the torsion spring as shown in the embodiment of fig. 3 and 4, but may be other elastic structures, such as a coil spring or a spring plate, etc., so long as the requirement that the normally driven restoring member 30 is in the first position and the restoring member 30 can move between the first position and the second position is satisfied.
In some embodiments of the present invention, as shown in fig. 2 and 4, both sides of the connection portion 31 may be provided with mounting shafts 311, and the filter screen support 10 may be provided with shaft holes 102, and the mounting shafts 311 may be inserted into the shaft holes 102, so as to realize connection between the reset member 30 and the filter screen support 10, and ensure that the reset member 30 can reliably pivot between the first position and the second position around the filter screen support 10, and the structure is simple and easy to operate.
Further, as shown in fig. 2-5, the connecting portion 31 may be a connecting plate, so as to connect the mating portion 32 and the stop portion 33, so that the structure is more firm, and the two mounting shafts 311 may be respectively disposed on two sides of one end of the connecting plate, so as to implement rotation of the reset member 30 around one end of the connecting plate. Optionally, a notch 312 may be formed at one end of the connecting plate, so that on one hand, the amount of raw materials is reduced, and the cost is reduced, while on the other hand, the notch 312 is formed at one end of the two mounting shafts 311, so that the reset element 30 and the filter screen bracket 10 can be conveniently mounted. The width of the connecting plate of the reset piece 30 can be equal to or slightly smaller than the distance between the shaft holes 102, when the reset piece is installed, only the two ends of the installation shaft 311 are required to be slightly pressed, so that the notch 312 is slightly deformed by extrusion, the distance between the opposite end surfaces of the two installation shafts 311 is slightly smaller than the width of the shaft hole 102 of the filter screen bracket 10, the installation shaft 311 can be easily inserted into the shaft hole 102, the notch 312 is restored after the installation, and the reset piece 30 is not easy to fall off.
According to some embodiments of the present invention, as shown in fig. 2 and 4, the connection portion 31 may be provided on a side surface of the screen support 10 facing away from the first screen 20, for example, on a lower side surface of the screen support 10, and the screen support 10 may be provided with a mounting opening 103, through which the fitting portion 32 and the stopper portion 33 protrude from the screen support 10. The shape of the mounting opening 103 is substantially the same as the shape of the mating portion 32 and the stop portion 33, so when the elastic member 40 applies a force to the reset member 30 toward the first filter screen 20, the connection portion 31 cannot pass through the mounting opening 103 due to the limitation of the filter screen bracket 10, and the reset member 30 is limited to the first position, so that the purpose that the elastic member 40 drives the reset member 30 to be always at the first position is achieved. In addition, when the first filter screen 20 reaches the reset piece 30, the first filter screen 20 can directly act on the guide inclined surface 321 of the matching part 32, so that the resistance is reduced, the excessive connection is better, the installation shaft 311 is favorably inserted into the shaft hole 102 of the filter screen bracket 10, and the connection is simple and convenient.
