Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an air conditioner. Background Technology

[0002] Traditional floor-standing air conditioners use a drive unit to rotate a cross-flow fan, which then directs airflow through vertically extending air outlets. When heating, the air outlets are angled downwards by a deflector, while when cooling, they are angled upwards. This results in a relatively short air delivery distance, poor overall comfort, and a tendency for air to be directed towards people. Utility Model Content

[0043] Traditional floor-standing air conditioners use a drive unit to rotate a cross-flow fan, which then directs airflow through vertically extending air outlets. When heating, the air outlets are angled downwards by a deflector, while when cooling, they are angled upwards. This results in a relatively short air delivery distance, poor overall comfort, and a tendency for air to be directed towards people.

[0044] This utility model proposes an air conditioner that separates the upper and lower air outlets of a vertical air conditioner and connects them in series to ensure the air outlet strength of both the upper and lower air outlets.

[0045] Please see Figures 1 to 10As shown, in one embodiment of the present invention, the air conditioner 100 includes a housing 10, an air outlet assembly 20, and a door opening and closing assembly 30. The housing 10 has a first air outlet 102 and a second air outlet 103 spaced apart along a first direction. The housing 10 has a through-flow duct 104 connecting the first air outlet 102 and the second air outlet 103. The air outlet assembly 20 includes a first air outlet component 21 and a second air outlet component 22 spaced apart along a first direction. The air supply side of the first air outlet component 21 faces the first air outlet 102 and connects to the through-flow duct 104. The air supply side of the second air outlet component 22 faces the second air outlet 103 and connects to the through-flow duct 104. The door opening and closing assembly 30 includes a first door 31 movably disposed at the first air outlet 102 and a second door 32 movably disposed at the second air outlet 103. The first door 31 is used to open and close the first air outlet 102, and the second door 32 is used to open and close the second air outlet 103.

[0046] It should be noted that the air conditioner 100 of this utility model can be a whole-type air conditioner 100, a split-type air conditioner 100, or an indoor unit including a split-type air conditioner 100.

[0047] In one embodiment, the air conditioner 100 is configured as a cabinet unit.

[0048] In one embodiment, the air conditioner 100 is configured as a split-type air conditioner 100 including a cabinet unit, and the housing 10 is disposed in the cabinet unit.

[0049] In this invention, the first direction can be along the height of the casing 10. The air conditioner 100 can be a cabinet air conditioner. The casing 10 is also provided with an air inlet 101, which can be located on the back of the casing 10. The first air outlet 102 and the second air outlet 103 can be located on the front of the casing 10, with the first air outlet 102 located on the upper side of the casing 10 and the second air outlet 103 located on the lower side of the casing 10. The air conditioner 100 of this invention also includes an indoor heat exchanger 40, which is located inside the casing 10 and between the air inlet 101 and the air outlet assembly 20. After the air conditioner 100 takes in air through the air inlet 101, it first exchanges heat with the indoor heat exchanger 40. The heat-exchanged air is then introduced by the air outlet assembly 20 and flows from the air outlet assembly 20 to the first air outlet 102 and the second air outlet 103.

[0050] When the air conditioner is in standby mode, the first air outlet 102 can be closed by the first switch door 31, and the second air outlet 103 can be closed by the second switch door 32. When the air conditioner 100 is in heating mode, the first switch 31 located at the first air outlet 102 can be activated to guide the airflow from the first air outlet 102 to the second air outlet 103. At this time, the first switch 31 can be in a closed state for the first air outlet 102, preventing the airflow from exiting the casing 10 from the first air outlet 102. Instead, the airflow flows downwards along the ventilation duct 104 to the second air outlet 103. Thus, during heating, the outside air is first guided to exchange heat with the indoor heat exchanger 40 through the first air outlet component 21 and the second air outlet component 22. Then, the first switch 31 guides the airflow from the first air outlet 102 through the ventilation duct 104 to the second air outlet 103, allowing the air conditioner 100 to enter through the second air outlet 103 near the lower side of the casing 10. When the air conditioner 100 is in cooling mode, the second switch 32 located at the second air outlet 103 can be activated to guide the air flowing towards the second air outlet 103 to the first air outlet 102. At this time, the second switch 32 can be closed at the second air outlet 103, and the airflow towards the second air outlet 103 cannot flow out of the casing 10 from the second air outlet 103. Instead, it can only flow upward along the ventilation duct 104 to the first air outlet 102. Thus, during cooling, the outside air is first guided to exchange heat with the indoor heat exchanger 40 through the first air outlet component 21 and the second air outlet component 22, and then the air flowing towards the second air outlet 103 is guided to the first air outlet 102 through the second switch 32, so that the air conditioner 100 can vent air through the first air outlet 102 near the upper side of the casing 10.

[0051] There are many ways to guide the airflow from the first air outlet 21 to the first air outlet 102 and the airflow from the second air outlet 22 to the second air outlet 103. For example, when the air outlet assembly 20 is working, the first air outlet 102 can be closed directly by the first switch door 31, preventing the airflow to the first air outlet 102 from flowing out and forcing it to flow to the second air outlet through the ventilation duct 104. Alternatively, the second air outlet 103 can be closed directly by the second switch door 32, preventing the airflow to the second air outlet 103 from flowing out and forcing it to flow to the first air outlet through the ventilation duct 104. This achieves the reversal of the airflow from the air conditioner 100, enabling both the first air outlet 21 and the second air outlet 22 to operate by discharging air through a single air outlet.

[0052] Alternatively, the first air outlet 21 can be positioned at an angle toward the ventilation duct 104, guiding the airflow from the first air outlet 102 into the ventilation duct 104 at an angle, and then through the ventilation duct 104 to the second air outlet 103. The second air outlet 22 can also be positioned at an angle toward the ventilation duct 104, guiding the airflow from the second air outlet 103 into the ventilation duct 104 at an angle, and then through the ventilation duct 104 to the first air outlet 102, thus achieving a working state where both the first air outlet 21 and the second air outlet 22 exit through a single air outlet.

[0053] The technical solution of this utility model involves providing a first air outlet 102 and a second air outlet 103 spaced apart along a first direction on a housing 10, providing a through-flow channel 104 connecting the first air outlet 102 and the second air outlet 103 inside the housing 10, and providing a first air outlet component 21 and a second air outlet component 22 spaced apart along the first direction inside the housing 10. The air outlet 21 is positioned with its air supply side facing the first air outlet 102, and the air outlet 22 is positioned with its air supply side facing the second air outlet 103. A first opening / closing door 31 is provided at the first air outlet 102, ensuring that the first opening / closing door 31 can at least allow air to flow towards the first air outlet 103 while the first air outlet 102 is closed. The air outlet 2 is guided along the inside of the casing 10 toward the second air outlet 103. A second switch door 32 is provided at the second air outlet 103 so that the second switch door 32 can guide the air flowing toward the second air outlet 103 along the inside of the casing 10 toward the first air outlet 102, at least when the second air outlet 103 is closed. When the first direction is up and down, the air conditioner 100 can guide the air to exchange heat inside the casing 10 through the two sets of air outlets when it is working. The air can be discharged through the first air outlet 102 near the upper side of the casing 10 or the second air outlet 103 near the lower side of the casing 10, thereby increasing the heat exchange air volume and the air delivery distance, while avoiding the air blowing directly onto the human body.

[0054] See Figure 3 , Figure 7 , Figure 9 As shown, in one embodiment, the through-ventilation duct 104 extends along a first direction and is located on one side of the air outlet assembly 20 along a second direction. The first switch door 31 is also used to guide the air flowing towards the first air outlet 102 to flow along the through-ventilation duct 104 toward the second air outlet 103. The second switch door 32 is also used to guide the air flowing towards the second air outlet 103 to flow along the through-ventilation duct 104 toward the second air outlet 103. The second direction is intersected with the first direction.

[0055] Thus, when air is guided from the first air outlet 102 to the second air outlet 103 through the first opening and closing door 31, and air is guided from the second air outlet 103 to the first air outlet 102 through the second opening and closing door 32, the airflow can be guided through the ventilation duct 104. When the airflow from the first air outlet 102 and the second air outlet 103 is switched, the airflow loss of the airflow inside the casing 10 can be reduced.

[0056] In the above embodiment, the second direction can be a front-to-back direction. The through-ventilation duct 104 can be disposed in front of the air outlet assembly 20 within the housing 10. The through-ventilation duct 104 can be formed by the front side wall, left side wall, and right side wall of the housing 10, together with the wall panel disposed within the housing 10. When the air flowing towards the first air outlet 102 is diverted and flows into the through-ventilation duct 104 by the first opening door 31, the lower side of the first opening door 31 can abut against the lower end of the first air outlet 102. The upper side of the switch door 31 can abut against the wall panel (to prevent air leakage when air flows into the ventilation duct 104). The first switch door 31 is tilted as a whole. When the first air outlet 21 discharges air towards the first air outlet 102, the air is guided by the tilted first switch door 31 into the ventilation duct 104 and flows from the ventilation duct 104 towards the second air outlet 103. It mixes with the air flowing from the second air outlet 22 towards the second air outlet 103 before flowing out, thereby increasing the flow rate at the second air outlet 103. When the second switch door 32 guides the air flowing towards the second air outlet 103 to flow into the ventilation duct 104, the second switch door 32 can use the same guiding method as the first switch door 31, which will not be described in detail.

[0057] The specific structures of the first air outlet component 21 and the second air outlet component 22 are described below. (See reference...) Figure 3 , Figure 5 , Figure 7 As shown, in one embodiment, the first air outlet 21 includes a first air duct shell 211 and a first impeller 212 disposed within the first air duct shell 211, and the second air outlet 22 includes a second air duct shell 221 and a second impeller 222 disposed within the second air duct shell 221. The first air duct shell 211 has a first air outlet 210, and the second air duct shell 221 has a second air outlet 220. The first air outlet 210 and the second air outlet 220 communicate with the through-flow duct 104. The first air outlet 210 is disposed opposite to the first air outlet 102, and the second air outlet 220 is disposed opposite to the second air outlet 103.

[0058] The first impeller 212 can be configured as a first centrifugal impeller, the second impeller 222 can be configured as a second centrifugal impeller, the first air outlet 210 can be the air outlet of the first air duct shell 211, and the second air outlet 220 can be the air outlet of the second air duct shell 221.

[0059] In this embodiment, since the first air supply port 210 and the first air outlet 102 are arranged opposite to each other, when the first switch door 31 opens the first air outlet 102 and does not guide the airflow from the first air outlet 102 toward the through-ventilation duct 104, the first air supply port 210 directly supplies air toward the first air outlet 102, thus connecting the first air supply port 210 and the first air outlet 102. When the first switch door 31 guides the airflow to the first air outlet 102 into the through-ventilation duct 104, the first air supply port 210 is connected to the second air outlet 103. Furthermore, since the second air supply port 220 and the second air outlet 103 are arranged opposite to each other, the second switch door 32 can be used to open and close the second air outlet 103 and guide the airflow to the second air outlet 103 into the through-ventilation duct 104. Therefore, the second air supply port 220 can be connected to the second air outlet 103, and the second air supply port 220 can be connected to the first air outlet 102.

[0060] See Figure 3 , Figure 7 , Figure 9 As shown, in one embodiment, the first switch door 31 is swayably disposed at the first air outlet 102 along a first direction. The first switch door has a first guiding state. When the first switch door is in the first guiding state, the first switch door is tilted upward toward the outside of the housing to divide the first air outlet into a first air outlet area and a second air outlet area. The second air outlet area is connected to the through-ventilation duct.

[0061] In this invention, the first direction can be vertical, and the first switch door 31 can swing vertically to guide the air at the first air outlet 102 to flow upward or downward. When the air from the second air outlet 103 is guided to the first air outlet 102 through the second switch door 32, the first switch door 31 can be swung upward to put it in a first guiding state. When the air conditioner 100 is discharging air through the first air outlet 102, the air can be delivered obliquely upward from the upper side of the air conditioner 100. The second air outlet area can be connected to the through-ventilation duct to guide the airflow in the through-ventilation duct, thereby further preventing the air conditioner 100 from blowing directly on the human body. Furthermore, when the air conditioner 100 is cooling, the upward parabolic airflow can be used to increase the air delivery distance and range.

[0062] In addition, the setting of the second switch door 32 can be made with reference to the first switch door 31. Optionally, the second switch door 32 is swayably disposed at the second air outlet 103 in the first direction. The second switch door has a second guiding state. When the second switch door is in the second guiding state, the second switch door is tilted downward toward the outside of the housing to divide the second air outlet into a third air outlet area and a fourth air outlet area. The third air outlet area is connected to the through-ventilation duct.

[0063] Thus, when the air from the first air outlet 102 is guided to the second air outlet 103 through the first switch door 31, the second switch door 32 can swing downwards, so that when the air conditioner 100 vents air through the second air outlet 103, it has a third air outlet area and a fourth air outlet area. The air is vented obliquely downwards from the lower side of the air conditioner 100, which can further prevent the air conditioner 100 from blowing directly on the human body. When the air conditioner 100 is heating, the oblique downwards and ground-level hot air can be used to increase the hot air flow distance. And by using the principle that hot air has low density and rises, the hot air can cover the indoor space from bottom to top, thereby increasing the air supply range.

[0064] In the above embodiments, the first switch door 31 can be swung in such a way that the first switch door 31 is connected to the inner walls of both sides of the first air outlet 102 via a pivot. The first switch door 31 can rotate via the pivot. The pivot can be installed near the lower side of the first switch door 31, that is, the distance between the pivot and the upper side of the first switch door 31 is greater than the distance between the pivot and the lower side of the first switch door 31. When the first switch door 31 swings counterclockwise via the pivot, the upper side of the first switch door 31 is more likely to abut against the wall panel, and the lower side of the first switch door 31 is more likely to abut against the lower end of the first air outlet 102. Thus, when air is guided into the ventilation duct 104 through the first switch door 31, air leakage is less likely to occur at the position of the first air outlet 102. When the first switch door 31 swings clockwise via the pivot, the lower side of the first switch door 31 is less likely to abut against the wall panel. When the first switch door 31 swings clockwise to a certain angle, the entire first air outlet 102 at the upper and lower ends of the first switch door 31 can be connected to the first air supply port 210 for air supply, thus ensuring the air volume when the first air supply port 210 is directed toward the first air outlet 102.

[0065] In addition, regarding the swingable arrangement of the second switch door 32, it can be arranged in a radially symmetrical manner with the first switch door 31 along the middle of the housing 10. The specific arrangement will not be elaborated.

[0066] When the air conditioner 100 discharges air through the first air outlet 102 and / or the second air outlet 103, to compensate for the insufficient airflow on both sides of the casing 10 and to enable the air conditioner 100 to achieve a wider airflow coverage on the front, refer to... Figure 4 , Figure 6 , Figure 8 As shown, in one embodiment, the housing 10 further has a third air outlet 105 and a fourth air outlet 106 spaced apart along a third direction;

[0067] The air outlet assembly also includes a third air outlet component 23, which is located between the first air outlet component 21 and the second air outlet component 22. The air outlet end of the third air outlet component 23 is connected to the third air outlet 105 and the fourth air outlet 106, wherein the first direction, the second direction and the third direction are arranged in pairs.

[0068] The first direction can be up and down, the second direction can be front and back, the third direction can be left and right, and the third air outlet 105 and the fourth air outlet 106 can be located between the first air outlet 102 and the second air outlet 103.

[0069] With this configuration, when the air conditioner 100 is discharging air through the first air outlet 102 and / or the second air outlet 103, it can also discharge air through the third air outlet 23 towards the third air outlet 105 and the fourth air outlet 106. This allows the air conditioner 100 to compensate for the insufficient air volume on both sides of the air conditioner 100 through the third air outlet 105 and the fourth air outlet 106. Furthermore, when the air conditioner 100 is working, it can also discharge air simultaneously through the first air outlet 102, the second air outlet 103, the third air outlet 105, and the fourth air outlet 106, thereby increasing the coverage area of ​​the air conditioner 100 and improving the heat exchange efficiency of the air conditioner 100.

[0070] Regarding the air outlet configuration of the third air outlet 105 and the fourth air outlet 106, this can be achieved by installing air ducts within the housing 10, connecting the third air outlet 105 to the third air outlet component 23, and connecting the fourth air outlet 106 to the third air outlet component 23. (See reference...) Figure 4 , Figure 10 As shown, in one embodiment, the housing 10 further has a side air duct 107, which has a first air duct section 1071 and a second air duct section 1072. The first air duct section 1071 is used to guide the third air outlet 23 to discharge air toward the third air outlet 105, and the second air duct section 1072 is used to guide the third air outlet 23 to discharge air toward the fourth air outlet 106.

[0071] The side air duct 107 can be a three-way air duct with three ports. The port connecting the side air duct 107 to the third air outlet 23 and the port connecting the side air duct 107 to the third air outlet 105 form a first air duct section 1071. The port connecting the side air duct 107 to the third air outlet 23 and the port connecting the side air duct 107 to the fourth air outlet 106 form a second air duct section 1072. The first air duct section 1071 and the second air duct section 1072 can share the same input port. In this way, when the third air outlet 23 discharges air, it can simultaneously discharge air towards the first air duct section 1071 and the second air duct section 1072. Thus, when the third air outlet 23 is working, air can be discharged at both the third air outlet 105 and the fourth air outlet 106, so that the air conditioner 100 can discharge air from the front near both sides at the same time.

[0072] Of course, in other embodiments, the first air duct section 1071 and the second air duct section 1072 may not share the same air inlet. The first air duct section 1071 and the second air duct section 1072 may be connected to the third air outlet component 23 with independent air inlet positions. Furthermore, a switch structure may be provided at the air inlet positions of the first air duct section 1071 and the second air duct section 1072 to control whether the third air outlet component 23 vents air towards the first air duct section 1071 and the second air duct section 1072. This allows the air conditioner 100 to independently control the air outlet on one side of the front, giving the air conditioner 100 more diversified air outlet methods.

[0073] See Figure 7 , Figure 10 As shown, in one embodiment, the third air outlet 23 includes a third air duct shell 231 and a third impeller 232 disposed within the third air duct shell 231. The third air duct shell 231 has a third air outlet 230. The third air outlet 230 is connected to the third air outlet 105 through the first air duct section 1071, and the third air outlet 230 is connected to the fourth air outlet 106 through the second air duct section 1072.

[0074] The third impeller 232 can be configured as a third centrifugal impeller, and the third air outlet 230 can be configured as the air outlet of the third air duct shell 231. The third air outlet 230 can be connected to the inlet of the first air duct section 1071 and the inlet of the second air duct section 1072. With this configuration, when the third impeller 232 rotates, it can guide the air that has undergone heat exchange in the third air duct shell 231 to flow into the first air duct section 1071 and the second air duct section 1072, and flow out from the third air outlet 105 and the fourth air outlet 106, so that air can be discharged from both sides of the first air outlet 102 and the second air outlet 103.

[0075] In this utility model, the number of third air outlet components 23 can be set to one, two, three, etc. The specific number can be selected according to the distance between the first air outlet component 21 and the second air outlet component 22, and no specific limitation is made here.

[0076] The formation of side air duct 107 is described below. Please refer to the following for further information. Figure 5 , Figure 10 As shown, in one embodiment, the air conditioner 100 further includes a side air duct housing 12, which is disposed within the through air duct 104. The side air duct housing 12 has an inlet, a first outlet, and a second outlet. A first air duct section 1071 is formed between the inlet and the first outlet, and a second air duct section 1072 is formed between the inlet and the second outlet. The inlet is connected to the third air supply outlet 230, the first outlet is connected to the third air outlet 105, and the second outlet is connected to the fourth air outlet 106.

[0077] This configuration allows the side air duct 107 to adopt a three-way design, with air intake through a single inlet and air outlets through the first and second outlets respectively. This enables the air conditioner 100 to simultaneously output air from both sides of the first air outlet 102 and the second air outlet 103 when air is discharged through the third air outlet 23. This avoids gaps between the first and second air duct sections 1071 and 1072 when they are connected to the third air outlet 230, which could lead to air leakage at the third air outlet 230. Furthermore, having only one inlet connecting to the third air outlet 230 saves on structural material for the side air duct shell 12, thus reducing the installation cost of the side air duct 107.

[0078] Additionally, when air is discharged from both sides of the first air outlet 102 and the second air outlet 103 through the third air outlet 105 and the fourth air outlet 106, to prevent the air from blowing directly onto the body from the side outlets, please refer to... Figure 5 , Figure 6 As shown, the air conditioner also includes an air guide 50, which is provided in the first air duct section 1071 and / or the second air duct section 1072. The air guide 50 is swayable along a first direction.

[0079] With this configuration, when air is discharged through the third air outlet 105 and the fourth air outlet 106, at least one of them can swing upward or downward through the air guide 50, so that the air blown out from the third air outlet 105 and the fourth air outlet 106 flows upward or downward, which can avoid direct blowing on the human body. When the air conditioner 100 sends air upward at an angle through the first air outlet 102, the third air outlet 105 and the fourth air outlet 106 can send air upward at an angle. When the air conditioner 100 sends air downward at an angle through the second air outlet 103, the third air outlet 105 and the fourth air outlet 106 can send air downward at an angle, thus meeting the current air supply mode requirements of the air conditioner 100.

[0080] When the air conditioner 100 is in standby mode, the first air outlet 102 and the second air outlet 103 can be closed through the first switch door 31 and the second switch door 32. To prevent foreign objects from entering the casing 10 from the third air outlet 105 and the fourth air outlet 106, this utility model also provides a third switch door 33 and a fourth switch door 34. (See reference...) Figure 1 , Figure 4 , Figure 10 As shown, in one embodiment, the door opening and closing assembly 30 further includes a third door 33 disposed at the third air outlet 105, the third door 33 being used to open and close the third air outlet 105;

[0081] And / or, the door opening and closing assembly 30 further includes a fourth door opening 34 disposed at the fourth air outlet 106, the fourth door opening 34 being used to open and close the fourth air outlet 106.

[0082] With this configuration, when the air conditioner 100 is in standby mode, the third air outlet 105 can be closed by the third switch door 33, and the fourth air outlet 106 can be closed by the fourth switch door 34, to prevent dust and foreign objects from entering the casing 10 from the third air outlet 105 and the fourth air outlet 106.

[0083] In this utility model, the driving method of the door opening and closing assembly 30 can be that an independent driving structure is set at each door opening and closing position, so that each door can rotate at its corresponding air outlet position to open and close the corresponding air outlet.

[0084] Alternatively, an independent drive structure can be provided, allowing the third switch door 33 to slide along the third air outlet 105 to open or close the third air outlet 105, and the fourth switch door 34 to slide along the fourth air outlet 106 to open or close the fourth air outlet 106; an independent drive mechanism can be provided, allowing the first switch door 31 (second switch door 32) to rotate at the first air outlet 102 (second air outlet 103) to open or close the first air outlet 102 (second air outlet 103), or to guide the air at the first air outlet 102 (second air outlet 103) to flow into the ventilation duct 104, or to guide the air at the first air outlet 102 to flow away from the second air outlet 103 (first air outlet 102).

[0085] Regarding the driving method of the first impeller 212, the second impeller 222, and the third impeller 232, each impeller can be equipped with an independent driving component to drive its corresponding impeller to rotate and generate airflow. Alternatively, the first impeller 212, the second impeller 222, and the third impeller 232 can be connected in series, with a single impeller driving component 60 driving all three impellers to rotate simultaneously, allowing multiple impellers to generate airflow at the same time. The relevant settings are as follows. (See reference...) Figure 3 As shown, in one embodiment, the air conditioner 100 further includes a fan drive 60 disposed in the housing 10, the fan drive 60 being used to drive the first fan 212, the second fan 222 and the third fan 232 to rotate.

[0086] The fan drive component 60 may include a motor and a drive shaft. The drive shaft extends vertically from the position of the first fan 212 to the position of the second fan 222, connecting the first fan 212, the third fan 232, and the second fan 222 respectively. Furthermore, the drive shaft is connected to the drive shaft of the motor, and the motor drives the drive shaft to rotate, enabling the first fan 212, the second fan 222, and the third fan 232 to rotate simultaneously. This configuration reduces the amount of fan drive structure required, saves internal space in the casing 10, and lowers the installation cost of the air conditioner 100.

[0087] When the first air outlet 21 is discharging air, in order to improve the air intake capacity of the first air outlet 21, the first air duct shell 211 may optionally have two first air inlets arranged opposite to each other along a first direction. The two first air inlets are respectively located on both sides of the axial direction of the first impeller 212, and the first air outlet 210 is located on the radial side of the first impeller 212. With this arrangement, the first air outlet 21 can simultaneously receive air through two oppositely arranged positions, which can increase the air intake volume of the first air outlet 21, thereby improving the air delivery volume of the first air outlet 21.

[0088] Furthermore, the second air duct housing 221 may also be provided with two second air inlets. Optionally, the second air duct housing 221 has two second air inlets arranged opposite to each other along the first direction. The two second air inlets are respectively located on both sides of the axial direction of the second impeller 222, and the second air outlet 220 is located on the radial side of the second impeller 222. With this arrangement, the second air outlet 22 can simultaneously receive air through two oppositely arranged positions, which can increase the air intake of the second air outlet 22 and thus improve the air delivery of the second air outlet 22.

[0089] Similar to the above embodiments, the third air duct housing 231 can also be provided with two third air inlets. Optionally, the third air duct housing 231 has two third air inlets arranged opposite to each other along the first direction. The two third air inlets are respectively located on both sides of the axial direction of the third impeller 232, and the third air outlet 230 is located on the radial side of the third impeller 232. With this arrangement, the third air outlet 23 can simultaneously receive air through two oppositely arranged positions, which can increase the air intake of the third air outlet 23, thereby increasing the air delivery volume of the third air outlet 23. Thus, when the first air duct housing 211, the second air duct housing 221, and the third air duct housing 223 are all provided with two oppositely arranged air inlets, the overall air delivery volume of the air conditioner 100 can be increased.

[0090] It is understood that the air conditioner 100 of this utility model can be configured as a cabinet air conditioner, a wall-mounted air conditioner, or a portable air conditioner, etc. When the air conditioner 100 of this utility model is configured as a cabinet air conditioner, optionally, the first air outlet 21, the third air outlet 23 and the second air outlet 22 are arranged sequentially in the vertical direction, and the housing 10 includes at least a panel located on the air outlet side of the air conditioner. The first air outlet 102 and the second air outlet 103 are respectively located on the upper and lower sides of the panel, and the third air outlet 105 and the fourth air outlet 106 are respectively located on the left and right sides of the panel. This allows the air conditioner 100 to discharge air diagonally upwards through the first air outlet 102 and diagonally upwards to both sides through the third air outlet 105 and the fourth air outlet 106, achieving a cooling air outlet mode and increasing the cooling air outlet range and delivery distance. It can also discharge air diagonally downwards through the second air outlet 103 and diagonally downwards through the third air outlet 105 and the fourth air outlet 106, achieving a heating air outlet mode and improving the downward air delivery effect for heating. Furthermore, during heating, horizontal airflow can be achieved through the third air outlet 105 and the fourth air outlet 106, avoiding the problem of poor heating stratification and temperature rise caused by the air conditioner 100 discharging all air towards the ground. The air conditioner 100 can also simultaneously discharge air through the first air outlet 102, the second air outlet 103, the third air outlet 105, and the fourth air outlet 106, forming a four-way air outlet effect, enriching the air delivery modes and meeting the diverse air delivery needs of users.
