DETAILED DESCRIPTION

[0047] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] Reference below Figures 1-11 An air conditioner 100 according to an embodiment of the present invention will be described.

[0049] Reference Figure 1 、 Figure 2 and Figure 4 According to an embodiment of the present invention, an air conditioner 100 includes a housing 1, an air duct assembly 2, a heat exchanger 3, and a fan assembly. An air inlet 11 is formed at the rear of the housing 1, and a first air outlet 12, a second air outlet 13, and a third air outlet 14 are formed at the front of the housing 1, arranged from top to bottom. The air duct assembly 2 includes an air inlet channel 21, a first air supply channel 22, a second air supply channel 23, and a third air supply channel 24. The heat exchanger 3 is disposed within the air inlet channel 21. The fan assembly includes a first fan 41, which is disposed within the air inlet channel 21. The air inlet 11 is connected to the air inlet channel 21, the first air supply channel 22 is connected to the air inlet channel 21 and the first air outlet 12, the second air supply channel 23 is connected to the air inlet channel 21 and the second air outlet 13, and the third air supply channel 24 is connected to the air inlet channel 21 and the third air outlet 14. When the air conditioner 100 is working, the first fan 41 can drive the air flow through the air inlet 11 into the air inlet channel 21 and flow to the heat exchanger 3. The air after heat exchange in the heat exchanger 3 can flow to the first air supply channel 22 or the second air supply channel 23 or the third air supply channel 24, and then be blown out to the room through the first air outlet 12 or the second air outlet 13 or the third air outlet 14 to cool or heat the room.

[0050] A first air outlet 12, a second air outlet 13 and a third air outlet 14 are formed on the front of the casing 1 and are arranged in sequence from top to bottom. The first air outlet 12, the second air outlet 13 and the third air outlet 14 can increase the air outlet area of ​​the air conditioner 100, thereby enhancing the air outlet effect of the air conditioner 100. By arranging the first air outlet 12, the second air outlet 13 and the third air outlet 14 in sequence from top to bottom, the air supply effect of the air conditioner 100 in different directions can be achieved.

[0051] The first air supply channel 22 extends upward in an upwardly inclined direction from rear to front, which can guide the airflow in the first air supply channel 22 over a long distance, and can guide the airflow in the first air supply channel 22 to flow upward, so that the airflow direction of the first air outlet 12 is upward, thereby enhancing the upward air supply effect of the airflow at the first air outlet 12. At least a portion of the second air supply channel 23 extends in the front-to-back direction, which can guide the airflow in the second air supply channel 23, and can guide the airflow in the second air supply channel 23 to flow forward, so that the airflow direction at the second air outlet 13 is toward the front of the housing 1, thereby achieving a forward air supply effect for the air conditioner 100. The fact that at least a portion of the second air supply channel 23 extends in the front-to-back direction may include the following situations: for example, the entire second air supply channel 23 may extend in the front-to-back direction; for another example, the second air supply channel 23 may extend in the front-to-back direction. The third air supply channel 24 extends downwardly in the direction from back to front, which can play a long-distance guiding role for the airflow in the third air supply channel 24, and can guide the airflow in the third air supply channel 24 to flow downward, so that the air outlet direction of the third air outlet 14 is downward, thereby enhancing the air supply effect of the downward airflow at the third air outlet 14.

[0052] For example, when the air conditioner 100 is in cooling mode, the first air supply channel 22 extends upward in an inclined manner from rear to front, thereby guiding the airflow upward over a long distance, so that the air outlet position is higher, which can reduce the discomfort caused by direct blowing, and the airflow blown out from the first air outlet 12 can be better directed upward, thereby improving the cooling effect of the air conditioner 100. Of course, the second air outlet 13 can also be controlled to open, so that air can be discharged upward through the first air outlet 12 and forward through the second air outlet 13 at the same time, thereby increasing the air outlet area of ​​the air conditioner 100 and further enhancing the cooling effect of the air conditioner 100.

[0053] For another example, when the air conditioner 100 is in heating mode, the third air supply duct 24 extends downwardly in a direction from back to front, which can guide the airflow downward over a long distance, so that the air outlet position is lower, which can achieve the function of warming the feet with hot air, and the airflow blown out from the third air outlet 14 can be better directed downward, thereby improving the heating effect of the air conditioner 100. Of course, the second air outlet 13 can also be controlled to open, so that air can be discharged downward through the third air outlet 14 while air can be discharged forward through the second air outlet 13. In this way, the air outlet area of ​​the air conditioner 100 can be increased, thereby further enhancing the heating effect of the air conditioner 100.

[0054] Through the long-distance downward guidance of the airflow by the third air supply channel 24, the airflow blown out from the third air outlet 14 can be better directed downward, thereby improving the heating effect of the air conditioner 100; in addition, a second air outlet 13 directed forward is provided at the same time, so that the air conditioner 100 can be directed forward when cooling / heating according to needs, thereby meeting more needs of users, further increasing the air supply area, and further improving the cooling / heating effect.

[0055] According to the air conditioner 100 of the embodiment of the present invention, the first air outlet 12, the second air outlet 13, the third air outlet 14 and the corresponding first air supply channel 22, the second air supply channel 23, and the third air supply channel 24 are formed in the front part of the casing 1 in sequence from top to bottom. By extending the first air supply channel 22 upward in an inclined direction from back to front, the first air supply channel 22 guides the airflow in the upward direction over a long distance, so that the airflow blown out of the first air outlet 12 can be better directed upward, thereby improving the cooling effect of the air conditioner 100. By extending the third air supply channel 24 downwardly in an inclined direction from the back to the front, and through the long-distance guiding effect of the third air supply channel 24 on the airflow in the downward direction, the airflow blown out from the third air outlet 14 can be better directed downward, thereby improving the heating effect of the air conditioner 100; in addition, a second air outlet 13 directed toward the front is provided at the same time, and the air conditioner 100 can be directed toward the front when cooling / heating according to needs, which can meet more needs of users, further increase the air supply area, and further improve the cooling / heating effect.

[0056] Reference Figure 4-Figure 6According to some embodiments of the present invention, the angle between the tangent direction of the end of the first air supply channel 22 and the horizontal direction is α, and the range of α is 20° to 50°. For example, α can be 20°, 30°, 35°, 40°, 50°, etc. When α is not less than 20°, the upward air supply effect of the air flow flowing out of the first air outlet 12 can be effectively achieved, thereby improving the cooling / heating effect of the air conditioner 100, thereby improving the user's comfort; when α is not greater than 50°, it can be ensured that the air flow direction of the first air outlet 12 is both upward and forward, ensuring the forward air supply effect of the air conditioner 100.

[0057] When the angle α is in the range of 20° to 50°, the air flow flowing out through the first air outlet 12 can be effectively supplied upward and forward.

[0058] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the angle between the tangent direction of the end of the third air supply channel 24 and the vertical direction is β, and the range of β is 10° to 45°. For example, β can be 10°, 20°, 30°, 40°, 45°, etc. When β is not less than 10°, the airflow flowing out of the third air outlet 14 can be effectively directed downward to achieve an air supply effect, thereby improving the cooling / heating effect of the air conditioner 100, thereby improving the user's comfort. When β is not greater than 45°, the airflow direction of the first air outlet 12 can be ensured to be both downward and forward, ensuring the forward air supply effect of the air conditioner 100.

[0059] When the angle β is in the range of 10° to 45°, the airflow flowing out through the third air outlet 14 can be effectively supplied downward and forward.

[0060] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the second air supply channel 23 includes a first air supply section 231 and a second air supply section 232. The second air supply section 232 is located on the downstream side of the first air supply section 231 and the air outlet end of the second air supply section 232 is opposite to the second air outlet 13. The second air supply section 232 extends in the front-to-back direction, and can guide the airflow entering the second air supply section 232, so that the airflow flows forward more smoothly and flows out from the second air outlet 13, so as to achieve the forward air supply effect of the air conditioner 100.

[0061] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the first air supply section 231 extends obliquely forward from bottom to top, which can guide the airflow in the first air supply section 231, so that the airflow entering the first air supply section 231 flows upward and forward, so that the airflow flows more smoothly to the second air supply section 232 and then flows out from the second air outlet 13, thereby achieving an air supply effect to the front of the air conditioner 100.

[0062] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the angle between the tangent direction at the end of the first air supply section 231 and the horizontal direction is γ, and the angle between the tangent direction at the end of the first air supply channel 22 and the horizontal direction is α, where γ<α. By ensuring that γ<α, the connection between the first air supply section 231 and the second air supply section 232 is smoother, allowing the airflow from the first air supply section 231 to flow more smoothly to the second air supply section 232, thereby achieving forward flow at the second air outlet 13. This can also reduce sudden changes in the airflow during flow, reducing or avoiding the possibility of noise caused by excessive sudden changes in the airflow.

[0063] Reference Figure 4-Figure 6 According to some embodiments of the present invention, γ ranges from 3° to 12°. For example, γ can be 3°, 5°, 8°, 10°, or 12°. By ensuring that γ is not less than 3°, the airflow in the first air supply section 231 can flow from bottom to top and forward. By ensuring that γ is not greater than 12°, a sudden change in the angle between the first air supply section 231 and the second air supply section 232 can be avoided, thereby reducing sudden changes in the airflow during flow and reducing or avoiding the possibility of noise generated by such sudden changes in the airflow.

[0064] By setting the angle γ to be in the range of 3° to 12°, it can be ensured that the airflow in the first air supply section 231 can flow from bottom to top and forward, and the sudden change of the airflow during the flow process can be reduced.

[0065] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the fan assembly also includes a second fan 42, which is arranged in the third air supply channel 24. The second fan 42 can drive the air after heat exchange in the heat exchanger 3 to flow toward the third air supply channel 24, and then flow out through the third air outlet 14, so as to effectively achieve the air supply effect at the third air outlet 14.

[0066] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the second fan 42 is a cross-flow fan, and the rotation axis of the second fan 42 extends in the left-right direction, so that the second fan 42 can drive the airflow after heat exchange in the heat exchanger 3 from bottom to top into the third air supply channel 24, and then blown out through the third air outlet 14, thereby effectively achieving the effect of the air conditioner 100 supplying air close to the ground.

[0067] Reference Figure 4-Figure 6 According to some embodiments of the present invention, a first air guide component 222 that can guide air up and down is provided in the first air supply channel 22, which can guide the airflow in the first air supply channel 22. By adjusting the rotation amplitude of the first air guide component 222, the direction of the airflow at the first air outlet 12 can be adjusted.

[0068] Reference Figure 4-Figure 6 According to some embodiments of the present invention, a second air guide component 233 that can guide the air left and right is provided in the second air supply channel 23, which can guide the airflow in the second air supply channel 23. By adjusting the rotation amplitude of the second air guide component 233, the direction of the airflow at the second air outlet 13 can be adjusted.

[0069] Reference Figure 4-Figure 6 According to some embodiments of the present invention, a first air guide assembly 222 is provided within the first air supply channel 22 to guide air upward and downward, and a second air guide assembly 233 is provided within the second air supply channel 23 to guide air left and right. The first air guide assembly 222 guides the airflow within the first air supply channel 22, and the second air guide assembly 233 guides the airflow within the second air supply channel 23. By adjusting the rotation amplitude of the first air guide assembly 222 or the second air guide assembly 233, the direction of the airflow at the corresponding air outlet can be adjusted.

[0070] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the first air supply channel 22, the second air supply channel 23, and the third air supply channel 24 are arranged sequentially from top to bottom. Since the first air outlet 12, the second air outlet 13, and the third air outlet 14 are arranged sequentially from top to bottom, the first air supply channel 22 connects the air inlet channel 21 and the first air outlet 12, the second air supply channel 23 connects the air inlet channel 21 and the second air outlet 13, and the third air supply channel 24 connects the air inlet channel 21 and the third air outlet 14. Since the first air supply channel 22, the second air supply channel 23, and the third air supply channel 24 are arranged sequentially from top to bottom, the air in the first air supply channel 22, the second air supply channel 23, or the third air supply channel 24 can flow out more smoothly through the corresponding air outlet, thereby realizing independent adjustment of different air outlet directions, thereby facilitating users to adjust different air outlet directions according to actual conditions, which is conducive to improving the user experience.

[0071] Reference Figure 4-Figure 6According to some embodiments of the present invention, the air duct assembly 2 includes a first air duct volute 25 and a second air duct volute 26 spaced apart in the up and down directions, the first air duct volute 25 is located above the second air duct volute 26, a first air supply channel 22 is formed in the first air duct volute 25, and a third air supply channel 24 is formed in the second air duct volute 26, the first air duct volute 25 and the second air duct volute 26 jointly define a second air supply channel 23, so that the first air supply channel 22, the second air supply channel 23 and the third air supply channel 24 can be arranged in sequence from top to bottom, so that the air in the first air supply channel 22 or the second air supply channel 23 or the third air supply channel 24 can flow out more smoothly through the corresponding air outlet, thereby realizing independent adjustment of different air outlet directions.

[0072] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the air conditioner 100 further includes a control component for controlling the connection or disconnection between the first air outlet 12 and the air inlet duct 21, the connection or disconnection between the second air outlet 13 and the air inlet duct 21, and the connection or disconnection between the third air outlet 14 and the air inlet duct 21. The control component can open or close the connection between the first air outlet 12, the second air outlet 13, and the third air outlet 14 and the air inlet duct 21, thereby controlling whether the airflow after heat exchange flows to the first air outlet 12, the second air outlet 13, and the third air outlet 14, thereby enabling the air conditioner 100 to control different air outlet directions.

[0073] For example, the control component can control the first air outlet 12 to be connected to the air inlet channel 21, the second air outlet 13 to be separated from the air inlet channel 21, and the third air outlet 14 to be separated from the air inlet channel 21. For example, when the air conditioner 100 is cooling, by connecting the first air outlet 12 to the air inlet channel 21, the cold air can be blown upward from the first air outlet 12, so that the air outlet position is higher, which can reduce the discomfort caused by direct blowing. When the user needs a stronger cooling effect, the first air outlet 12 can be controlled to be connected to the air inlet channel 21, the second air outlet 13 to be connected to the air inlet channel 21, and the third air outlet 14 to be separated from the air inlet channel 21. This increases the air outlet area to enhance the cooling effect, thereby better meeting the user's usage needs.

[0074] For another example, the control component can control the first air outlet 12 to be isolated from the air inlet channel 21, the second air outlet 13 to be isolated from the air inlet channel 21, and the third air outlet 14 to be connected to the air inlet channel 21. For example, when the air conditioner 100 is heating, the third air outlet 14 is connected to the air inlet channel 21, so that the air outlet position is lower, and the hot air warming function can be achieved. When the user requires a stronger heating effect, the first air outlet 12 can be controlled to be connected to the air inlet channel 21, the second air outlet 13 can be controlled to be connected to the air inlet channel 21, and the third air outlet 14 can be controlled to be connected to the air inlet channel 21. This increases the air outlet area to enhance the heating effect, thereby better meeting the user's usage needs.

[0075] Of course, when the user needs a stronger cooling / heating effect, the control component can be used to control the first air outlet 12, the second air outlet 13 and the third air outlet 14 to be connected to the air inlet channel 21. At this time, the air outlet area of ​​the air conditioner 100 can be further expanded, thereby further enhancing the cooling / heating effect of the air conditioner 100.

[0076] For another example, the control component can control the first air outlet 12 to be separated from the air inlet channel 21, the second air outlet 13 to be connected to the air inlet channel 21, and the third air outlet 14 to be separated from the air inlet channel 21. At this time, air is only supplied to the front of the air conditioner 100.

[0077] By controlling the connection or disconnection between the first air outlet 12 and the air inlet channel 21, the connection or disconnection between the second air outlet 13 and the air inlet channel 21, and the connection or disconnection between the third air outlet 14 and the air inlet channel 21, the air conditioner 100 can control different air outlet directions.

[0078] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the control component includes a damper 51, which is arranged at the air flow inlet 221 end of the first air supply channel 22 to open and close the air flow inlet 221 of the first air supply channel 22. By controlling the position of the damper 51, it is possible to control whether the air flow after heat exchange flows into the first air supply channel 22, thereby controlling whether the first air outlet 12 discharges air or not.

[0079] Reference Figure 4-Figure 6According to some embodiments of the present invention, a damper 51 is rotatably mounted on the air duct assembly 2 between a first position and a second position. In the first position, the damper 51 closes the air inlet 221 of the first air supply channel 22; in the second position, the damper 51 opens the air inlet 221 of the first air supply channel 22. The damper 51 extends vertically and defines a guide channel 511 between the damper 51 and the housing 1. The guide channel 511 connects the air inlet 21 with the first air supply channel 22. When the damper 51 is in the first position, the damper 51 closes the air inlet 221 of the first air supply channel 22, and no air flows out of the first air outlet 12. When the damper 51 is in the second position, the damper 51 opens the air inlet 221 of the first air supply channel 22. The heat-exchanged air can flow through the guide channel 511 into the first air supply channel 22 and then be blown out through the first air outlet 12, effectively achieving an upward air flow effect for the air conditioner 100. The guide channel 511 can guide the airflow in the air inlet channel 21 so that the airflow can flow more smoothly into the first air supply channel 22 .

[0080] Reference Figure 7-Figure 9 According to some embodiments of the present invention, the control assembly includes a switch door 52 that can be moved up and down to open and close the second air outlet 13. By controlling the position of the switch door 52, the second air outlet 13 can be opened or closed. For example, when the switch door 52 is located above or below the second air outlet 13, the second air outlet 13 is opened, and air can be blown out of the second air outlet 13, thereby achieving a forward air supply effect of the air conditioner 100.

[0081] Reference Figure 4 、 Figure 5 and Figure 9 According to some embodiments of the present invention, when the switch door 52 is in the position to open the second air outlet 13, the switch door 52 is located above the second air outlet 13 and within the storage space defined by the air duct assembly 2 and the housing 1. When the switch door 52 is in the position to open the second air outlet 13, the switch door 52 is located within the storage space, which can prevent the switch door 52 from blocking the airflow at the second air outlet 13 and affecting the air discharge effect at the second air outlet 13, and can also make the switch door 52, the air duct assembly 2, and the housing 1 more compact.

[0082] Reference Figure 7-Figure 9According to some embodiments of the present invention, the control assembly includes a first drive assembly 53 for driving the switch door 52.

The first transmission rack 534 is fixed to the switch door 52 and extends in the vertical direction. The first transmission gear 533 is transmission-connected to the first drive motor 531. When the first drive motor 531 is in operation, it can drive the first transmission gear 533 to rotate. The rotation of the first conventional gear can cause relative movement with the first transmission rack 534. Since the first transmission rack 534 extends in the vertical direction, the first transmission gear 533 and the first transmission rack 534 can move relative to each other in the vertical direction, thereby enabling the first drive motor 531 to drive the switch door 52 to move in the vertical direction, thereby opening or closing the second air outlet 13.

[0083] Optionally, refer to Figure 7-Figure 9 Guide columns 521 are formed on both sides of the switch door 52 along the left and right directions, and slide rails 131 are formed on the casing 1 on the opposite sides of the second air outlet 13. The guide columns 521 are slidably arranged in the slide rails 131, so that the guide columns 521 can move along the set trajectory and direction, thereby ensuring that the switch door 52 moves along the set trajectory and direction, reducing or avoiding the possibility of the switch door 52 deviating during movement.

[0084] Reference Figure 3 、 Figure 5 and Figure 6 According to some embodiments of the present invention, the control assembly includes a guide plate 54, which is used to open and close the third air outlet 14. By controlling the position of the guide plate 54, the third air outlet 14 can be opened or closed, thereby controlling the downward air supply direction of the air conditioner 100.

[0085] Reference Figure 4-Figure 6According to some embodiments of the present invention, the deflector 54 is rotatably provided on the housing 1 or the air duct assembly 2 between a third position and a fourth position. In the third position, the deflector 54 closes the third air outlet 14; in the fourth position, the deflector 54 opens the third air outlet 14. The deflector 54 is located in the third air supply channel 24 and is used to guide the airflow. By controlling the rotation angle of the deflector 54, the third air outlet 14 can be opened or closed. When the deflector 54 is in the third position, the third air outlet 14 is closed. When the deflector 54 is in the fourth position, the third air outlet 14 is opened. The deflector 54 is located in the third air supply channel 24 and can guide the airflow in the third air supply channel 24, so that the airflow in the third air supply channel 24 can flow out more smoothly toward the third air outlet 14, thereby achieving a downward air supply effect of the air conditioner 100.

[0086] Reference Figure 5 、 Figure 6 and Figure 10 According to some embodiments of the present invention, the control assembly includes a second drive assembly 55 for driving the deflector 54 to move. The second drive assembly 55 includes a second drive motor 551 and a second transmission mechanism 552. The second transmission mechanism 552 includes a transmission rod 553. The second drive motor 551 is fixed to the housing 1 or the air duct assembly 2. The housing 1 or the air duct assembly 2 can provide support and fixation for the second drive motor 551. The transmission rod 553 extends in the front-to-back direction. The second drive motor 551 is transmission-connected to the transmission rod 553 to drive the transmission rod 553 to move in the front-to-back direction. The lower end of the deflector 54 is rotatably connected to the housing 1 or the air duct assembly 2, and the transmission rod 553 is movably connected to the upper end of the deflector 54. When the second drive motor 551 is working, it can drive the transmission rod 553 to move in the front-to-back direction. The movement of the transmission rod 553 in the front-to-back direction can drive the guide plate 54 to move in the front-to-back direction, thereby realizing that the second drive motor 551 drives the guide plate 54 to move between the third position and the fourth position in the front-to-back direction to open or close the third air outlet 14.

[0087] Reference Figure 8 、 Figure 10 and Figure 11According to some embodiments of the present invention, the second transmission mechanism 552 includes a meshed second transmission gear and a second transmission rack. The second transmission rack is fixed to the transmission rod 553 and extends in the front-to-back direction. The second transmission gear is transmission-connected to the second drive motor 551. The meshed connection between the second transmission gear and the second transmission rack enables a transmission connection between the second transmission gear and the second transmission rack. When the second drive motor 551 is in operation, it can drive the second transmission gear to rotate. The rotation of the second transmission gear can cause relative movement of the second transmission rack in the front-to-back direction, thereby driving the deflector 54 to move between a third position and a fourth position in the front-to-back direction, thereby opening or closing the third air outlet 14.

[0088] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the first fan 41 is located below the first air supply duct 22, the second air supply duct 23, and the third air supply duct 24, and the heat exchanger 3 is located above the first fan 41, with the exhaust port of the first fan 41 facing upward. The first fan 41 can drive airflow through the air inlet 11 and into the air inlet duct 21. Because the exhaust port of the first fan 41 faces upward and the heat exchanger 3 is located above the first fan 41, the airflow can be directly driven toward the heat exchanger 3, which helps to improve the heat exchange effect of the heat exchanger 3 on the airflow.

[0089] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the first fan 41 is an axial flow fan, and the rotation axis of the first fan 41 extends in the up and down directions, so that the first fan 41 can drive the airflow from the lower air inlet 11 into the air inlet channel 21 and flow upward toward the heat exchanger 3, ensuring the heat exchange effect of the heat exchanger 3 on the airflow.

[0090] Reference Figure 4-Figure 6 According to some embodiments of the present invention, the heat exchanger 3 includes a first heat exchange section 31 and a second heat exchange section 32. The upper end of the first heat exchange section 31 is connected to the upper end of the second heat exchange section 32. From top to bottom, the first heat exchange section 31 and the second heat exchange section 32 extend obliquely away from each other. The exhaust port of the first fan 41 is located between the lower end of the first heat exchange section 31 and the lower end of the second heat exchange section 32. This increases the contact area between the heat exchanger 3 and the airflow. The airflow flowing out of the exhaust port of the first fan 41 can flow directly to the first heat exchange section 31 and the second heat exchange section 32 for heat exchange, thereby improving the heat exchange effect of the heat exchanger 3 on the airflow.

[0091] In addition, a water collecting pan may be provided at the lower end of the first heat exchange part 31 and the lower end of the second heat exchange part 32, which may be inclined and extended in directions away from each other by the first heat exchange part 31 and the second heat exchange part 32. This may guide the water, so that the water collecting pan may be convenient for collecting the water formed on the surface of the first heat exchange part 31 or the second heat exchange part 32, thereby reducing or avoiding the possibility of the water formed on the surface of the first heat exchange part 31 or the second heat exchange part 32 directly falling into the interior of the casing 1.

[0099] A first air guide assembly 222 capable of guiding air upward and downward is provided in the first air supply channel 22 , and a second air guide assembly 233 capable of guiding air leftward and rightward is provided in the second air supply channel 23 .

[0100] The control assembly includes a damper 51, a switch door 52, and a deflector 54. The damper 51 is located at the airflow inlet 221 of the first air supply channel 22 to open and close the airflow inlet 221 of the first air supply channel 22. The damper 51 is rotatably mounted on the air duct assembly 2 between a first position and a second position. In the first position, the damper 51 closes the airflow inlet 221 of the first air supply channel 22; in the second position, the damper 51 opens the airflow inlet 221 of the first air supply channel 22. The damper 51 extends vertically and defines a guide channel 511 between the damper 51 and the housing 1. The guide channel 511 connects the air inlet channel 21 with the first air supply channel 22.

[0101] The switch door 52 can move up and down to open and close the second air outlet 13. When the switch door 52 is in the position of opening the second air outlet 13, the switch door 52 is located above the second air outlet 13 and in the storage space defined by the air duct assembly 2 and the housing 1.

[0102] The deflector 54 is used to open and close the third air outlet 14.
