Specifically, as shown in fig. 1 to 3, the driving assembly 5 includes a first electromagnet 51 and a second electromagnet 52, and a fitting block 53 that can be magnetically fitted with the first electromagnet 51 and the second electromagnet 52, alternatively, the fitting block 53 may be a permanent magnet block or a metal block (e.g., an iron block, a copper block, etc.), the first electromagnet 51 and the second electromagnet 52 are fixed in the open opening 11 at intervals in the front-rear direction, and the fitting block 53 is provided on the connecting rod 3. The matching block 53 can attract or repel the first electromagnet 51 and the second electromagnet 52, and the magnetic force action between the matching block 53 and the first electromagnet 51 and the second electromagnet 52 can be changed by controlling the power-on and power-off states of the first electromagnet 51 and the second electromagnet 52, so that the connecting rod 3 can be switched among the first position, the second position and the third position.
Further, as shown in fig. 1 to 3, the engaging block 53 is provided on the top of the connecting rod 3, the first electromagnet 51 and the second electromagnet 52 are provided on the top wall 111 of the open opening 11, and the bottom wall of the second electromagnet 52 is higher than the bottom wall of the first electromagnet 51, when the connecting rod 3 is located at the first position, the engaging block 53 is offset from the first electromagnet 51, the engaging block 53 is offset from the second electromagnet 52 in the up-down front-back direction, when the connecting rod 3 is located at the second position, the engaging block 53 is opposite to the second electromagnet 52 in the up-down direction, and when the connecting rod 3 is located at the third position, the engaging block 53 is opposite to the first electromagnet 51 in the front-back direction.
Specifically, when the first electromagnet 51 and the second electromagnet 52 are energized, the first electromagnet 51 and the second electromagnet 52 have magnetism, and when the first electromagnet 51 and the second electromagnet 52 are not energized, the first electromagnet 51 and the second electromagnet 52 disappear from magnetism. The following describes a process of adjusting the wind guiding angle of the air guiding strip 2 of the air conditioner by taking two specific examples as examples.
The first embodiment is as follows:
the matching block 53 is a permanent magnet, when the first electromagnet 51 and the second electromagnet 52 are not electrified, magnetic attraction can be generated between the first electromagnet 51 and the matching block 53, and between the second electromagnet 52 and the matching block 53, and when the first electromagnet 51 and the second electromagnet 52 are electrified, magnetic repulsion force can be generated between the first electromagnet 51 and the matching block 53, and between the second electromagnet 52 and the matching block 53.
When the air conditioner is in a cooling operation mode and the air conditioner needs to be controlled to draw air along a substantially horizontal direction, at the moment, the first electromagnet 51 and the second electromagnet 52 are both controlled to be electrified, so that repulsive forces are generated between the first electromagnet 51 and the matching block 53 and between the second electromagnet 52 and the matching block 53, under the repulsive forces, the matching block 53 and the first electromagnet 51 as well as the matching block 53 and the second electromagnet 52 are staggered in the vertical front-rear direction (as shown in fig. 1), so that the connecting rod 3 is moved to the first position, and meanwhile, the air guide strip 2 is located at a substantially horizontal air guide position, so that the air conditioner guides air along a substantially horizontal direction.
When the air conditioner is in a heating working mode and the air conditioner needs to be controlled to lead air obliquely downwards, the first electromagnet 51 is controlled to be electrified, the second electromagnet 52 is not electrified, the suction force of the first electromagnet 51 to the matching block 53 disappears, the second electromagnet 52 has suction force to the matching block 53, the matching block 53 moves to the position shown in fig. 2 under the action of the suction force of the second electromagnet 52, the matching block 53 is opposite to the second electromagnet 52 in the vertical direction, so that the connecting rod 3 moves to the second position, and meanwhile, the air guide strip 2 extends downwards in the direction from back to front in a downward inclined mode, so that the air conditioner is obliquely led downwards to lead air out, and the heating requirement of the air conditioner is met. It should be noted that, when the connecting rod 3 is located at the second position, the engagement block 53 and the second electromagnet 52 may or may not be in contact, and whether the engagement block 53 and the second electromagnet 52 are in contact or not is related to the length of the connecting rod 3.
When the air conditioner is shut down, the opening 11 needs to be closed at this time, the first electromagnet 51 can be controlled not to be electrified at this time, the second electromagnet is electrified, the attraction force of the second electromagnet 52 to the matching block 53 disappears at this time, the first electromagnet 51 generates the attraction force action to the matching block 53, the matching block 53 moves to the position shown in fig. 3 under the action of the attraction force of the first electromagnet 51, the matching block 53 is opposite to the first electromagnet 51 in the front-back direction, so that the connecting rod 3 moves to the third position, and meanwhile, the air guide strip 2 extends in the up-down direction to close the opening 11 of the face frame 1. The engagement piece 53 may or may not be in contact with the first electromagnet 51.
Alternatively, the magnetic force acting forces between the first electromagnet 51 and the second electromagnet 52 and the mating block 53 are different, and specifically, the sizes of the cross-sectional areas, the lengths, and the like of the iron cores of the first electromagnet 51 and the second electromagnet 52 may be different, so that the attraction forces generated to the mating block 53 when the first electromagnet 51 and the second electromagnet 52 are not electrified are different. For example, when the first electromagnet 51 and the second electromagnet 52 are not energized, the attraction force of the first electromagnet 51 to the fitting block 53 is greater than the attraction force of the second electromagnet 52 to the fitting block 53, so that when the air conditioner stops and the open opening 11 of the face frame 1 needs to be closed, the first electromagnet 51 and the second electromagnet 52 can be controlled not to be energized, and since the attraction force of the first electromagnet 51 to the fitting block 53 is greater than the attraction force of the second electromagnet 52 to the fitting block 53, the fitting block 53 will be driven to the position shown in fig. 3, the fitting block 53 is opposed to the first electromagnet 51 in the front-rear direction, so that the link 3 is moved to the third position, and at the same time, the air guide strip 2 extends in the up-down direction to close the open opening 11 of the face frame 1.
Example two:
the matching block 53 is a metal block, for example, an iron block or a copper block, when the first electromagnet 51 and the second electromagnet 52 are not energized, a magnetic attraction effect is not generated between the first electromagnet 51 and the matching block 53, and between the second electromagnet 52 and the matching block 53, and when the first electromagnet 51 and the second electromagnet 52 are energized, a magnetic attraction effect is generated between the first electromagnet 51 and the matching block 53, and between the second electromagnet 52 and the matching block 53.
When the air conditioner is in a refrigeration working mode and the air conditioner needs to be controlled to lead out air along a substantially horizontal direction, the first electromagnet 51 and the second electromagnet 52 are controlled not to be electrified, so that no suction effect is generated between the first electromagnet 51 and the matching block 53 and between the second electromagnet 52 and the matching block 53, the connecting rod 3 is located at a first position shown in fig. 1 under the action of self gravity, the matching block 53 and the first electromagnet 51 as well as the matching block 53 and the second electromagnet 52 are staggered in the up-down front-back direction, and the air guide strip 2 is located at a substantially horizontal air guide position, so that the air conditioner can guide air along the substantially horizontal direction.
When the air conditioner is in a heating working mode and the air conditioner needs to be controlled to lead air obliquely downwards, the first electromagnet 51 is controlled not to be electrified, the second electromagnet 52 is electrified, the first electromagnet 51 does not generate a suction effect on the matching block 53, the second electromagnet 52 has a suction effect on the matching block 53, the matching block 53 moves to the position shown in fig. 2 under the suction effect of the second electromagnet 52, the matching block 53 is opposite to the second electromagnet 52 in the vertical direction, so that the connecting rod 3 moves to the second position, and meanwhile, the air guide strip 2 extends downwards in the direction from back to front in a downward inclined mode, so that the air conditioner can lead air obliquely downwards to lead out and heat, and the requirement of the air conditioner is met. It should be noted that, when the connecting rod 3 is located at the second position, the engagement block 53 and the second electromagnet 52 may or may not be in contact, and whether the engagement block 53 and the second electromagnet 52 are in contact or not is related to the length of the connecting rod 3.
When the air conditioner is shut down, the open opening 11 needs to be closed at this time, the first electromagnet 51 can be controlled to be powered on, the second electromagnet 52 is not powered on at this time, the second electromagnet 52 does not generate an attraction effect on the matching block 53, the first electromagnet 51 generates an attraction effect on the matching block 53, the matching block 53 moves to the position shown in fig. 3 under the action of the attraction force of the first electromagnet 51, the matching block 53 is opposite to the first electromagnet 51 in the front-rear direction, so that the connecting rod 3 moves to the third position, and meanwhile, the air guide strip 2 extends in the up-down direction to close the open opening 11 of the face frame 1. The engagement piece 53 may or may not be in contact with the first electromagnet 51.
Alternatively, the magnetic force acting forces between the first electromagnet 51, the second electromagnet 52 and the matching block 53 are different, and specifically, the attractive force generated by the first electromagnet 51 and the second electromagnet 52 to the matching block 53 when the electromagnet is energized may be different by making the cross-sectional areas of the iron core of the first electromagnet 51 and the iron core of the second electromagnet 52 different, making the turns of the coil different or making the current passing through the coil different. For example, when the first electromagnet 51 and the second electromagnet 52 are energized, the attraction force of the first electromagnet 51 to the fitting block 53 is greater than the attraction force of the second electromagnet 52 to the fitting block 53, so that when the air conditioner stops and the open opening 11 of the face frame 1 needs to be closed, the first electromagnet 51 and the second electromagnet 52 can be both energized, and since the attraction force of the first electromagnet 51 to the fitting block 53 is greater than the attraction force of the second electromagnet 52 to the fitting block 53, the fitting block 53 will be driven to the position shown in fig. 3, the fitting block 53 will be opposed to the first electromagnet 51 in the front-rear direction, so that the connecting rod 3 is moved to the third position, and at the same time, the air guide strip 2 extends in the up-down direction to close the open opening 11 of the face frame 1.

Preferably, a portion of the top wall 111 of the open hole 11 between the first mounting hole and the second mounting hole is formed in a flat or curved shape extending from the rear to the front, thereby preventing interference between the engagement block 53 and the top wall 111 of the face frame 1 when the link 3 is switched and moved between the first position, the second position and the third position, and making the movement of the link 3 in the face frame 1 smoother.
It will be appreciated that the link 3 can be positioned in the second and third positions by the magnetic force between the engagement block 53 and the first and second electromagnets 51 and 52 when the link 3 is in the second or third position, and that the link 3 needs to be supported on a support structure to be able to position the link 3 in the first position when the link 3 is in the first position, for example by having the link 3 supported on the bottom wall 112 of the opening 11.
In an optional embodiment of the present invention, the air outlet panel assembly 100 further includes a stopper 6, the stopper 6 is disposed on the bottom wall 112 of the open opening 11, the stopper 6 is used for positioning the connecting rod 3 at the first position, and by disposing the stopper 6 on the bottom wall 112 of the open opening 11, the connecting rod 3 can be more flexibly assembled, and the connecting rod 3 can be positioned at the first position without supporting the connecting rod 3 on the bottom wall 112 of the open opening 11.
Alternatively, the position-limiting member 6 may be a cushion block (not shown) disposed on the bottom wall 112 of the face frame 1, and the height of the cushion block is set according to actual requirements, so that the connecting rod 3 is supported on the cushion block when the connecting rod 3 is located at the first position.

And when the connecting rod 3 moves from the third position to the second position or the first position, the connecting rod 3 can move rapidly to the position under the action of the spring.
