Therefore, the heat exchange port 103 vertically arranged on one side of the shell 100 can reduce dust falling when the heat exchange port 103 is opened, reduce deposition of dirt on the heat exchanger 102 and reduce influence on performance of an air conditioner.

Optionally, the heat exchanging port 103 is closed, which means that the included angle between the plane of the guide plate 200 and the vertical plane of the heat exchanging port 103 is 0 degree or 180 degrees. Therefore, when the included angle between the plane of the guide plate 200 and the vertical plane of the heat exchange port 103 is 0 degree or 180 degrees, the guide plate 200 seals the heat exchange port 103, so that dirt in the air is prevented from entering the interior of the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of the air conditioner is reduced.

Optionally, the controller 400 further includes: and a second control unit 402 electrically connected to the driving device 300 and configured to control one end of the guide plate 200 facing the outside of the heat exchange port 103 to be inclined upward when there is rain and to control one end of the guide plate 200 facing the outside of the heat exchange port 103 to be inclined downward when there is no rain. Therefore, when rain exists, the second control unit 402 controls the driving device 300 to drive one end of the guide plate 200 facing the outer side of the heat exchange port 103 to incline upwards to drain rainwater, the rainwater is drained to the heat exchanger 102 in the outdoor unit, dirt on the heat exchanger 102 is washed away, and then the heat exchange performance is improved.

Alternatively, the end of the guide plate 200 facing the outside of the heat exchange port 103 refers to the end of the guide plate 200 away from the heat exchanger 102 when the heat exchange port 103 is opened. Thus, the end of the guide plate 200 facing the outside of the heat exchange port 103 is controlled to be inclined downwards or upwards according to the external weather and the working state of the air conditioner, so that the dirt in the air is reduced from entering the inside of the outdoor unit, and the heat exchange performance of the heat exchanger 102 is improved.

Alternatively, the end of the guide plate 200 that is inclined downward toward the outside of the heat exchange port 103 means that the horizontal plane of the guide plate 200 that is perpendicular to the plane of the heat exchange port 103 has an inclined downward angle. In this way, the guide plate 200 is inclined downwards towards the outer end of the heat exchange port 103, so that dirt in the air can be prevented from entering the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of the air conditioner is reduced.

Alternatively, the end of the guide plate 200 facing the outside of the heat exchange port 103 is inclined upward, which means that the horizontal plane of the guide plate 200 perpendicular to the plane of the heat exchange port 103 has an upward inclination angle. Therefore, the end of the guide plate 200 facing the outside of the heat exchange port 103 is inclined upwards to guide rainwater to the heat exchanger 102 inside the outdoor unit, so that dirt on the heat exchanger 102 is washed away, and the heat exchange performance is improved.

Optionally, the second control unit 402 is further configured to control an angle at which one end of the guide plate 200 facing the outside of the heat exchange port 103 is inclined upward according to the amount of rain. Therefore, when the rainfall is different, the upward-inclined angle of one end, facing the outer side of the heat exchange port 103, of the guide plate 200 can be controlled to drain rainwater, so that the washing effect of the drained rainwater on the heat exchanger 102 in the indoor unit can be improved, the upward-inclined angle of one end, facing the outer side of the heat exchange port 103, of the guide plate 200 can be controlled to be smaller when the rainfall is larger, the heat exchanger 102 in the indoor unit can be protected from being damaged by rainwater with larger strength, and the service life of the heat exchanger 102 is prolonged.

Optionally, the guide plate 200 is provided in plurality and arranged longitudinally near the heat exchanging port 103. Therefore, the rotation and adjustment of the guide plate 200 are facilitated, the occupied area of the guide plate 200 on the protection device can be reduced on the premise of not influencing the heat exchange performance of the heat exchanger 102, the size of the protection device is further reduced, and the production of the protection device is facilitated.

Optionally, a plurality of guide plates 200 are arranged near the heat exchange port 103 in a longitudinal direction perpendicular to the vertical surface of the heat exchange port 103 and cover the heat exchange port 103. Thus, the inclination angle of the guide plate 200 is controlled by controlling the rotation of the guide plate 200, thereby opening or closing the heat exchange port 103.

Optionally, the plurality of guide plates 200 are evenly spaced apart and spaced apart by a distance less than the width of the guide plates 200. Therefore, after the guide plates 200 are uniformly inclined to one side, the guide plates 200 can be contacted with each other to form a closed surface to close the heat exchange port 103, so that the guide plates 200 have a good closed effect when closing the heat exchange port 103, dirt in air can be prevented from entering the interior of the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of an air conditioner is reduced.

Optionally, the end of the guide plate 200 facing the outside of the heat exchanging port 103 is provided with a sealing strip 201. Therefore, when the heat exchange port 103 is closed, the sealing strip 201 on the guide plate 200 contacts with the other guide plate 200, so that the heat exchange port 103 is better sealed, dirt in the air is prevented from entering the interior of the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of the air conditioner is reduced.

Optionally, a water tank is disposed on the outer side surface of the guide plate 200. Therefore, when rain exists, the water tank can collect and guide the dripping rainwater, when one end of the guide plate 200 facing the outer side of the heat exchange port 103 inclines upwards, the drainage rainwater enters the interior of the outdoor unit, the washing effect of the heat exchanger 102 in the interior of the outdoor unit is improved, the heat exchange performance of the heat exchanger 102 is further improved, when one end of the guide plate 200 facing the outer side of the heat exchange port 103 inclines downwards, the drainage rainwater is discharged, more rainwater is prevented from entering the interior of the outdoor unit, and the influence of the rainwater on the heat exchange performance of the heat exchanger 102 is reduced.

Alternatively, the outer side surface of the guide plate 200 refers to a surface of the guide plate 200 that is away from the heat exchange port 103 when the heat exchange port 103 is closed. Therefore, rainwater can be guided to enter the outdoor unit to wash the heat exchanger 102 when one end of the guide plate 200 facing the outer side of the heat exchange port 103 inclines upwards, and rainwater can be guided to be discharged when one end of the guide plate 200 facing the outer side of the heat exchange port 103 inclines downwards, so that more rainwater is prevented from entering the outdoor unit, and the influence of the rainwater on the heat exchange performance of the heat exchanger 102 is reduced.

Optionally, the water tank is provided in plurality and is uniformly arranged on the outer side surface of the guide plate 200 along the vertical direction of the guide plate 200. Therefore, the water tanks uniformly distributed in the vertical direction of the extension guide plate 200 can better collect and guide the dripping rainwater, and the washing effect of the guided rainwater on the heat exchanger 102 in the indoor unit is improved.

Alternatively, a plurality of guide plates 200 are connected to the same driving device 300, and configured to be driven by one driving device 300 in synchronization with the plurality of guide plates 200. Thus, the guide plates 200 are driven by the same driving device 300, so that the guide plates 200 can synchronously rotate, the production cost of the device is reduced, and the sealing effect of the guide plates 200 when the heat exchange ports 103 are sealed is enhanced. The specific structure of the guide plate 200 connected to the same driving device 300 can refer to the connection structure of the indoor unit air deflector in the prior art.

Optionally, an angle of the guide plate 200 inclining upward toward an end outside the heat exchanging port 103 is less than or equal to 60 degrees. Therefore, when the rainfall of the rainwater is different, the upward-inclined angles of the end, facing the outer side of the heat exchange port 103, of the guide plate 200 can be controlled to drain the rainwater, so that the washing effect of the drained rainwater on the heat exchanger 102 in the indoor unit is improved, the upward-inclined angles of the end, facing the outer side of the heat exchange port 103, of the guide plate 200 can be controlled to be different when the rainfall is large, the heat exchanger 102 in the indoor unit is protected from being damaged by the rainwater with large intensity, and the service life of the heat exchanger 102 is prolonged.

Alternatively, the larger the amount of rain, the larger the angle at which the end of the guide plate 200 facing the outside of the heat exchange port 103 is inclined upward. Thus, the larger the angle of upward inclination of one end of the guide plate 200 facing the outside of the heat exchange port 103, the smaller the area of the heat exchange port 103 exposed on the upper side of the guide plate 200, the amount of rainwater entering can be reduced, and the damage to the inside of the outdoor unit caused by excessive rainwater entering due to excessive rainfall can be prevented; on the contrary, the smaller the upward inclination angle of the end of the guide plate 200 facing the outside of the heat exchange port 103, the larger the area of the heat exchange port 103 exposed on the upper side of the guide plate 200, and more rainwater can be collected when the rainwater is smaller, so as to sufficiently wash and clean the heat exchanger 102. For example, when the rainfall is less, the angle of the upward inclination of one end of the guide plate 200 facing the outer side of the heat exchange port 103 is greater than 0 degree and less than or equal to 45 degrees, so that the guide plate 200 can collect more rainwater, the washing effect of the rainwater on the heat exchanger 102 in the indoor unit is improved, and the heat exchange performance of the heat exchanger 102 is further improved; when the rainfall is more, the upward inclined angle of one end of the guide plate 200 facing the outer side of the heat exchange port 103 is greater than 45 degrees and less than or equal to 60 degrees, so that the heat exchanger 102 is fully washed by the drainage rainwater, meanwhile, a large amount of rainwater is prevented from entering an outdoor unit, the interior of the indoor unit is prevented from being damaged, and the service life of the heat exchanger 102 is prolonged.

Optionally, an angle of the guide plate 200 inclining downward toward an end outside the heat exchanging port 103 is less than or equal to 90 degrees. Thus, the end of the guide plate 200 facing the outside of the heat exchange port 103 is inclined downward by different angles, so that dirt in the air can be prevented from entering the outdoor unit when the air conditioner is in a working state, or the heat exchange port 103 is closed when the air conditioner is in a non-working state, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of the air conditioner is reduced.

Optionally, the end of the guide plate 200 facing the outside of the heat exchanging port 103 is inclined downward by 90 degrees. Thus, when the outdoor unit is in a non-working state, the guide plate 200 inclines downwards by 90 degrees towards one end of the outer side of the heat exchange port 103 to close the heat exchange port 103, so that dirt in the air is prevented from entering the inside of the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the performance of an air conditioner is reduced.

Optionally, the end of the guide plate 200 facing the outside of the heat exchanging port 103 is inclined downward by 60 degrees. Thus, when the outdoor unit is in a working state, one end of the guide plate 200 facing the outside of the heat exchange port 103 is controlled to be inclined downwards by 60 degrees, so that the heat exchange performance of the outdoor unit in working can be ensured, the dirt in the air can be reduced to fall into the outdoor unit, the deposition amount of the dirt on the heat exchanger 102 is reduced, and the influence on the air conditioning performance is reduced.
