The detailed description in the detailed implementation manners should be understood as an explanatory illustration of the purpose of the present application and should not be regarded as an improper limitation to the present application.

[0039] An embodiment of the present invention provides an air conditioner. Referring to Figures 1 to 6 , the air conditioner includes a housing 10, a wind wheel 20, a first heat exchanger 30 and a second heat exchanger 40 located on the refrigerant circulation circuit, and an air guiding component.

[0040] The housing 10 provides an installation position for other components in the air conditioner. The external shape of the housing 10 is designed according to a preset usage scenario. For example, when the air conditioner is hung and installed on the ceiling, the outer shell is cube-shaped so that the outer shell can be embedded in the ceiling sandwich and keep the appearance of the ceiling flat.

[0041] The housing 10 is provided with a separated installation cavity 10d and an energy storage cavity 10e. The housing 10 is provided with an air inlet 10a, an internal circulation air outlet 10b, and an external circulation air outlet 10c. The air inlet 10a, the internal circulation air outlet 10b, and the external circulation air outlet 10c are all communicated with the installation cavity 10d to provide a passage for air flow to enter and exit the installation cavity 10d.

[0042] It can be understood that the air inlet 10a and the internal circulation air outlet 10b are communicated with the environment where the temperature needs to be adjusted, such as indoors, inside a vehicle, etc. The external circulation air outlet 10c is communicated with the external environment, such as outdoors, outside a vehicle, etc.

[0043] The energy storage cavity 10e is filled with a medium for storing or releasing heat.

[0044] The impeller 20 is arranged in the installation cavity 10d.

[0045] By the rotation of the impeller 20, the gas flow in the installation cavity 10d is driven, so that the air flow flows out of the installation cavity 10d from the internal circulation air outlet 10b or the external circulation air outlet 10c. At the same time, since the air pressure difference is formed between the installation cavity 10d and the outside world after the air flow flows out, the outside air flows into the installation cavity 10d from the air inlet 10a, thereby achieving the purpose of continuous air flow in and out of the installation cavity 10d.

[0046] It can be understood that the air conditioner includes an impeller motor for driving the impeller 20 to rotate. The impeller motor can be arranged outside the housing 10 or in the installation cavity 10d, and can be flexibly selected according to the preset usage scenario of the air conditioner.

[0047] It can be understood that the impeller 20 can be a centrifugal fan or an axial flow fan. For example, referring to Figure 5 and Figure 6 , an axial flow fan is adopted, so as to reduce the operating noise of the air conditioner and improve the user experience on the premise of meeting the air flow rate.

[0048] The first heat exchanger 30 is located in the installation cavity 10d, and the second heat exchanger 40 is located in the energy storage cavity 10e. The first heat exchanger 30 is used to absorb or release heat from the air flow passing through the installation cavity 10d, and the second heat exchanger 40 is used to absorb or release heat from the air in the energy storage cavity 10e. Heat exchange can be carried out between the first heat exchanger 30 and the second heat exchanger 40 through a refrigerant circulation loop, that is, the heat in the installation cavity 10d can be brought into the energy storage cavity 10e, or the heat in the energy storage cavity 10e can be brought into the installation cavity 10d, so as to achieve the purpose of regulating the temperature of the air flow in the installation cavity 10d.

[0049] It should be noted that the technical principles and specific structures of the first heat exchanger 30 and the second heat exchanger 40 have been widely used in the related art, so they will not be elaborated here.

[0050] It can be understood that a heat insulation material is laid on the inner wall corresponding to the energy storage cavity 10e, so that the medium in the energy storage cavity 10e can be kept warm for a long time, improving the working efficiency of the air conditioner and reducing power consumption.

[0051] Both the first heat exchanger 30 and the second heat exchanger 40 are integrated into the housing 10. Compared with the situation in the related art where the two heat exchangers are separately placed indoors and outdoors, it is convenient for the installation of the air conditioner, making the air conditioner compact in size and easy to install in a narrow space such as a ceiling interlayer.

[0052] The specific material of the heat insulation material is not limited. For example, polyurethane foam, ceramic fiber, glass wool, etc. have the characteristics of large thermal resistance, low thermal conductivity, high thermal reflectivity, easy to manufacture and install, and low cost.

[0053] The air guiding component is arranged in the installation cavity 10d to alternatively cover the inner circulation air outlet 10b or the outer circulation air outlet 10c.

[0054] The air conditioner includes an outer circulation mode (the indoor air is discharged outdoors after passing through the air conditioner) and an inner circulation mode (the indoor air is discharged indoors after passing through the air conditioner).

[0055] In the inner circulation mode, the air guiding component covers the outer circulation air outlet 10c, and an inner circulation air flow channel is formed between the air inlet 10a and the inner circulation air outlet 10b.

[0056] It can be understood that in the inner circulation mode, the air flow flows into the installation cavity 10d from the air inlet 10a and exchanges heat with the first heat exchanger 30, so that the temperature of the air flow rises or falls, and then the air flow flows out from the inner circulation air outlet 10b.

[0057] In the outer circulation mode, the air guiding component covers the inner circulation air outlet 10b, and an outer circulation air flow channel is formed between the air inlet 10a and the outer circulation air outlet 10c.

[0058] It can be understood that in the external circulation mode, the air flow flows into the installation cavity 10d from the air inlet 10a, exchanges heat with the first heat exchanger 30, so that the temperature of the air flow rises or falls, and then the air flow flows out from the external circulation air outlet 10c.

[0059] The heat exchange state of the first heat exchanger 30 with the air flow in the internal circulation mode and the external circulation mode is opposite. So that heat can be introduced into or exported from the medium in the energy storage cavity 10e through the heat exchange between the first heat exchanger 30 and the second heat exchanger 40, so as to achieve the purpose of temperature regulation.

[0060] In the case of cooling the environment that needs to be temperature-regulated, first, the air conditioner is in the external circulation mode. The second heat exchanger 40 conducts the heat of the medium in the energy storage cavity 10e to the first heat exchanger 30. The air flow in the external circulation air flow channel takes away the heat on the first heat exchanger 30 and is discharged to the outside through the external circulation air outlet 10c, so that the temperature of the medium in the energy storage cavity 10e can be reduced. Then, the air conditioner is in the internal circulation mode. The first heat exchanger 30 conducts heat to the medium in the energy storage cavity 10e through the second heat exchanger 40, so that the air flow in the internal circulation air flow channel flowing through the first heat exchanger 30 is cooled, and the cooled air flow is discharged through the internal circulation air outlet.

[0061] By intermittently starting the air conditioner, the medium in the energy storage cavity 10e is maintained at a lower temperature. After the user needs to perform a cooling operation, due to the lower temperature of the medium in the energy storage cavity 10e, the air conditioner can quickly provide cold air through the internal circulation mode, improving the cooling speed and enhancing the user experience. It is suitable for use scenarios with small spaces such as kitchens and bathrooms.

[0062] In the air conditioner according to the embodiment of the present invention, by arranging the first heat exchanger 30 in the installation cavity 10d and arranging the second heat exchanger 40 in the energy storage cavity 10e, through the heat exchange between the first heat exchanger 30 and the second heat exchanger 40, heat can be stored in the medium in the energy storage cavity 10e or the heat of the medium in the energy storage cavity 10e can be released. By covering the internal circulation air outlet 10b or the external circulation air outlet 10c with the air guiding assembly, the air flow can discharge the heat of the first heat exchanger 30 through the external circulation air outlet 10c, achieving the purpose of storing cold in the medium in the energy storage cavity 10e, or exchanging the heat of the air flow to the second heat exchanger 40 through the first heat exchanger 30, so that the cooled air flow is discharged from the internal circulation air outlet 10b, realizing the cooling function of the air conditioner. The medium in the energy storage cavity 10e can be pre-cooled and cold-stored, enabling the air conditioner to achieve rapid cooling and improving the user experience. Both the first heat exchanger 30 and the second heat exchanger 40 are arranged in the machine shell 10, and there is no need to separately arrange a heat exchanger outdoors, reducing the occupied space of the air conditioner and improving the adaptability.

[0063] It can be understood that in the external circulation mode, the first heat exchanger 30 and the second heat exchanger 40 can be in a non-operating state, that is, only the air flow is discharged from the air inlet 10a to the external circulation air outlet 10c, so as to achieve the purpose of ventilation and reduce the energy consumption of the air conditioner.

[0064] It can be understood that the specific structure of the air guiding component is beneficial to guiding the flow direction of the air flow.

[0065] In some embodiments, referring to Figures 2 to 6 , the air guiding component includes a volute 50, a volute tongue plate 60 and a driving member 70. A guiding cavity 50a is provided in the volute 50, and the air wheel 20 is arranged in the guiding cavity 50a. An air flow inlet 50b, a first air flow outlet 50c communicated with the internal circulation air outlet 10b, and a second air flow outlet 50d communicated with the external circulation air outlet 10c are provided on the volute 50. The volute 50 can protect the air wheel 20, and the air flow in the guiding cavity 50a flows under the agitation of the air wheel 20. Under the constraint of the inner wall of the guiding cavity 50a, the air flow is guided to flow in a preset direction. On the one hand, the energy loss during the air flow movement is reduced, so that the air flow flowing out from the external circulation air outlet 10c or the internal circulation air outlet 10b meets the flow requirements; on the other hand, the impact of the air flow on other devices in the installation cavity 10d is reduced, thereby reducing the noise during the operation of the air conditioner and improving the user experience.

[0066] Referring to Figure 7 and Figure 8 , in the external circulation mode, the driving member 70 drives the volute tongue plate 60 to open the second air flow outlet 50d and close the first air flow outlet 50c, thereby cutting off the connection between the first air flow outlet 50c and the internal circulation air outlet 10b, and achieving the purpose of covering the internal circulation air outlet 10b by the air guiding component. In the internal circulation mode, the driving member 70 drives the volute tongue plate 60 to open the first air flow outlet 50c and close the second air flow outlet 50d, thereby cutting off the connection between the second air flow outlet 50d and the external circulation air outlet 10c, and achieving the purpose of covering the external circulation air outlet 10c by the air guiding component.

[0067] The volute tongue plate 60 alternately opens and closes the first air flow outlet 50c or the second air flow outlet 50d. On the one hand, it avoids setting an independent opening and closing mechanism at the first air flow outlet 50c and / or the second air flow outlet 50d, simplifies the structure of the air guiding component, reduces the number of parts, improves the reliability, and reduces the occupied space of the air guiding component in the installation cavity 10d; on the other hand, it avoids rotating the entire volute 50 to change the air supply direction, reduces the structural weight, and improves the reliability.

[0068] It can be understood that the volute 50 is covered outside the air wheel 20, and the cross-section of the inner wall of the guiding cavity 50a along the axial direction of the air wheel 20 is circular and spaced from the air wheel 20. Referring to Figure 2On the one hand, it avoids interference between the rotation of the wind wheel 20 and the volute 50; on the other hand, it reduces the space occupied by the volute 50 in the installation cavity 10d, making the structure compact.

[0069] It can be understood that the arrangement positions of the volute tongue plate 60 and the driving member 70 relative to the volute 50 facilitate the flow of air in the air guiding cavity 50a.

[0070] In some embodiments, referring to Figure 2 , the volute tongue plate 60 is arranged in the air guiding cavity 50a. It avoids interference and friction between the volute tongue plate 60 and the relevant circuits and devices in the installation cavity 10d during the movement due to the volute tongue plate 60 being arranged on the outer surface of the volute 50, facilitating the arrangement of the relevant circuits and devices in the installation cavity 10d.

[0071] In some embodiments, referring to Figure 2 and Figure 5 , the driving member 70 is located axially outside the volute 50. The driving member 70 is located outside the air guiding cavity 50a, reducing the volume of the air guiding cavity 50a, avoiding friction and impact between the air flow in the air guiding cavity 50a and the driving member 70 during the flow process, thereby reducing the air flow energy loss and generating noise, thus reducing the power consumption of the air conditioner and improving the user experience.

[0072] It can be understood that the moving direction of the volute tongue plate 60 is the same as the air flow direction in the air guiding cavity 50a. Thus, it reduces the resistance of the air flow received by the volute tongue plate 60 during the movement, reduces the load during the operation of the driving member 70, and reduces the power consumption.

[0073] It can be understood that the structure of the air guiding assembly is conducive to the diversion of the air flow during the process of flowing through the first air outlet 50c and the second air outlet 50d, thereby reducing noise.

[0074] In some embodiments, referring to Figure 2 and Figure 5 , the volute 50 is provided with a first volute tongue 521. The first volute tongue 521 is located at the edge of the first air outlet 50c. One end of the first volute tongue 521 facing the air flow direction is arc-shaped. In the internal circulation mode, a part of the air flow hitting the surface of the first volute tongue 521 is guided back to the air guiding cavity 50a, and the other part is guided into the first air outlet 50c; the surface of the first volute tongue 521 has a smooth transition, which can reduce the impact of the air flow on the first volute tongue 521, thereby reducing the noise generated during the process of the first volute tongue 521 cutting the air flow.

[0075] In some embodiments, referring to Figure 2 and Figure 5, the scroll tongue plate 60 includes a wind deflector 62 and a second scroll tongue 61. The second scroll tongue 61 is located at one end of the wind deflector 62 away from the first air outlet 50c. One end of the second scroll tongue 61 facing the air flow direction is arc-shaped. In the external circulation mode, part of the air flow hitting the surface of the second scroll tongue 61 is guided back to the air guide cavity 50a, and the other part is guided into the second air outlet 50d; the surface of the second scroll tongue 61 is smoothly transitioned, which can reduce the impact of the air flow on the second scroll tongue 61, thereby reducing the noise generated during the process of the second scroll tongue 61 cutting the air flow.

[0076] It can be understood that the position of the scroll tongue plate 60 and the shape of the volute 50 are reasonably arranged to reduce the noise generated by the first scroll tongue 521 and the second scroll tongue 61 in the state of not cutting the air flow.

[0077] In some embodiments, refer to Figure 2 , Figure 7 and Figure 8 , when the air conditioner is in the external circulation mode, the scroll tongue plate 60 blocks the first air outlet 50c, the first scroll tongue 521 is located outside the air guide cavity 50a, and the second scroll tongue 61 forms the air outlet duct of the air conditioner (the second scroll tongue 61 is the scroll tongue of the air outlet duct of the air conditioner). It avoids the air flow in the air guide cavity 50a from entering the space between the first scroll tongue 521 and the wind deflector 62, reduces the probability of the air flow in the air guide cavity 50a becoming turbulent due to the generated eddy current, and reduces the noise.

[0078] When the air conditioner is in the internal circulation mode, the wind deflector blocks the second air outlet, the second scroll tongue 61 is located outside the air guide cavity 50a, and the first scroll tongue 521 forms the air outlet duct of the air conditioner (the first scroll tongue 521 is the scroll tongue of the air outlet duct of the air conditioner). It avoids the air flow in the air guide cavity 50a from entering the space between the second scroll tongue 61 and the volute 50, reduces the probability of the air flow in the air guide cavity 50a becoming turbulent due to the generated eddy current, and reduces the noise.

[0079] It can be understood that there is an accommodation space in the volute 50. In the internal circulation mode, the second scroll tongue 61 is located in the accommodation space, so that the transition between the wind deflector 62 and the inner wall of the air guide cavity 50a is smooth, reducing the resistance and noise of the air flow.

[0080] It can be understood that an auxiliary structure is provided in the air guide assembly to restrict the movement trajectory of the scroll tongue plate 60 and improve the movement stability of the scroll tongue plate 60.

[0081] In some embodiments, refer to Figure 2 , Figure 3 and Figure 5, both the first air outlet 50c and the second air outlet 50d are provided in the circumferential direction of the volute 50. This reduces the path of the airflow flowing radially generated by the wind wheel 20 from flowing out of the first air outlet 50c and the second air outlet 50d, reduces the energy loss of the airflow, and lowers the power consumption of the air conditioner.

[0082] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , a guiding groove 50f is provided on the inner wall of the air guiding cavity 50a along the axial direction. The scroll tongue plate 60 includes a limiting protrusion 63 provided at the end, and the limiting protrusion 63 is received in the guiding groove 50f and can slide in the guiding groove. This enables the two ends of the scroll tongue plate 60 along the axial direction to be limited and supported by the driving member 70 and the limiting protrusion 63 respectively. On the one hand, it avoids the load of the scroll tongue plate 60 being concentrated at the connection position between the scroll tongue plate 60 and the driving member 70, improving the connection stability between the two; on the other hand, the limiting protrusion 63 can suppress the vibration of the end of the scroll tongue plate 60 far from the driving member 70 under the impact of the airflow, reducing the amount of airflow overflow caused by the deformation of the scroll tongue plate 60 under the action of the airflow force, thereby reducing the power consumption of the air conditioner.

[0083] It can be understood that the guiding groove 50f is a blind groove to prevent the airflow from passing through the guiding groove 50f and entering outside the volute 50, avoiding the resulting noise and airflow flow loss.

[0084] In some embodiments, referring to Figure 2 , Figure 3 and Figure 5 , a guiding hole 50e is formed on the side wall of the air guiding cavity 50a along the axial direction. An installation groove is formed at the end of the scroll tongue plate 60. The driving member 70 includes an installation member that cooperates with the installation groove. The installation member passes through the guiding hole 50e and is connected to the installation groove, and the driving member 70 drives the installation member to move along the guiding hole 50e.

[0085] In some embodiments, a guiding hole 50e is formed on the side wall of the air guiding cavity 50a along the axial direction. The scroll tongue plate 60 includes a connecting member provided at the end. The driving member 70 is formed with a connecting groove that cooperates with the connecting member. The connecting member passes through the guiding hole 50e and is connected to the connecting groove, and the driving member 70 drives the connecting member to move along the guiding hole 50e.

[0086] The driving member 70 is drivingly connected to the scroll tongue plate 60 through the penetrating guiding hole 50e. The extending direction of the guiding hole 50e is the same as the moving direction of the scroll tongue plate 60, thus playing a role of restraint and guidance. The guiding hole 50e is provided in the axial direction of the volute 50. To restrain the circumferential movement of the scroll tongue plate 60 along the volute 50, thereby achieving the purpose of blocking the first air outlet 50c and the second air outlet 50d.

[0088] In some embodiments, referring to Figure 2 , Figure 7 and Figure 8 , the volute tongue plate 60 moves around the wind wheel 20, the wind baffle 62 is arc-shaped, and the concave side of the wind baffle 62 faces the wind wheel 20. This enables the wind baffle to swing around the wind wheel 20 to alternately block the first air outlet 50c or the second air outlet 50d. At the same time, the wind baffle 62 is arc-shaped to be adapted to the circumferential direction of the wind wheel 20, so that the distance between the wind wheel 20 and the volute tongue plate 60 can be reduced, and the space required for the movement of the wind baffle 62 can be reduced, thereby reducing the volume of the air guide cavity 50a, making the structure of the air guide assembly more compact and contributing to improving the overall installation adaptability of the air conditioner.

[0089] It can be understood that the way the driving member 70 drives the volute tongue plate 60 to move can reduce the space occupied in the installation cavity 10d, making the structure of the air conditioner compact.

[0090] In some embodiments, referring to Figure 3 , Figure 4 and Figure 5 , the driving member 70 includes a motor 73, a gear 72 and an arc-shaped rack 71. The gear 72 is arranged on the motor shaft of the motor 73 and meshes with the arc-shaped rack 71. The arc-shaped rack 71 is connected to the volute tongue plate 60 to drive the volute tongue plate 60 to move. The motor 73 drives the gear 72 to rotate. Through the meshing of the gear 72 and the arc-shaped rack 71, the rotation of the gear 72 is converted into the movement of the arc-shaped rack 71, and then the volute tongue plate 60 is driven to move.

[0091] The arc-shaped rack 71 is arc-shaped, which can make the movement path of the volute tongue plate 60 adapt to the circumferential outer shape of the volute 50.

The mounting seat 74 is arranged at one axial end of the volute 50, and the motor 73 is detachably mounted on the mounting seat 74. The motor 73 is fixed on the mounting seat 74 so that relative rotation occurs between the motor 73 and the gear 72.

[0094] It can be understood that a limiting structure is provided on the air guide assembly to reduce the probability of disengagement between the gear 72 and the arc-shaped rack 71.

[0095] In some embodiments, referring toFigure 3 and Figure 5 On the axial outer side of the volute 50, an arc-shaped guide groove 50g is provided, and an arc-shaped rack 71 is slidably arranged in the arc-shaped guide groove 50g. The inner wall of the arc-shaped guide groove 50g plays a constraining role on the arc-shaped rack 71, reducing the probability of separation between the arc-shaped rack 71 and the gear 72, improving the reliability. At the same time, it is also convenient to pre-position the installation position of the arc-shaped rack 71 during the assembly process, improving the assembly efficiency.

[0096] In some embodiments, referring to Figure 5 , an avoidance notch 50h is provided on the side wall of the arc-shaped guide groove 50g, and the gear 72 and the arc-shaped rack 71 are engaged and driven in the avoidance notch 50h. This avoids interference of the arc-shaped guide groove 50g with the movement of the arc-shaped rack 71 and the gear 72.

[0097] It can be understood that the specific structure of the volute 50 facilitates the assembly and the installation of related parts.

[0098] In some embodiments, referring to Figures 2 to 5 , the volute 50 includes a first half shell 51 and a second half shell 52. The first half shell 51 and the second half shell 52 are connected along the radial direction of the wind wheel 20 and enclose to form a wind guiding cavity 50a. During the assembly of the wind guiding component, first, parts such as the wind wheel 20 are installed in the first half shell 51 or the second half shell 52, and then the first half shell 51 and the second half shell 52 are connected, avoiding opening a large installation hole on a single volute 50 for parts such as the wind wheel 20 to pass through, reducing the escape of air flow. At the same time, it reduces the shielding of the volute 50 during the installation process, improving the installation efficiency.

[0099] The connection between the first half shell 51 and the second half shell 52 is detachable, facilitating subsequent repair and maintenance. The specific form of the detachable connection is not limited, such as screw thread connection, elastic snap and hole fit connection, etc.

[0100] In some embodiments, referring to Figure 2 and Figure 5 , the axial edge of the first half shell 51 and the axial edge of the second half shell 52 are spaced apart to form an air inlet 50b. Avoiding separately opening the air inlet 50b on the first half shell 51 or the second half shell 52 reduces the manufacturing steps and the production cost.

[0101] It can be understood that the layout positions of the components on the air conditioner are adapted to its specific application scenarios.

[0102] In some embodiments where the air conditioner is a ceiling-mounted unit, referring to Figures 2 to 4 , an air inlet 10a and an inner circulation air outlet 10b are provided on the bottom side of the housing 10. This is to extract air from the room and re-send the air flow with the temperature adjusted back into the room.

[0103] It can be understood that the arrangement of the components inside the housing 10 is adapted to the air inlet 10a and the inner circulation air outlet 10b located at the bottom side of the housing 10.

[0104] In some embodiments, referring to Figure 2 and Figure 5 , the radially bottom side edge of the first half housing 51 is spaced from the radially bottom side edge of the second half housing 52 to form a first air outlet 50c. Avoiding setting a separate first air outlet 50c on the first half housing 51 or the second half housing 52 reduces the manufacturing steps and lowers the production cost. The second air outlet 50d is provided on the side of the first half housing 51 radially away from the second half housing 52.

[0105] In some embodiments, the rotation angle range of the volute tongue plate is 60° to 80°, specifically, the range is 60°, 70°, 80°, etc. So that there is a sufficient distance between the first air outlet 50c and the second air outlet 50d, and both have sufficient cross-sectional areas to meet the air flow rate requirements.

[0106] In some embodiments, the number of driving members 70 is two, and the two driving members 70 are respectively located at one end of the volute 50 along the axial direction. The two driving members 70 share the load during the movement of the volute tongue plate 60, improve the reliability of the movement of the volute tongue plate 60, reduce the driving power required by the driving members 70, and reduce the structural size.

[0107] It can be understood that an auxiliary device is provided in the air conditioner to improve the heating effect of the air conditioner.

[0108] In some embodiments, referring to Figures 2 to 4 , the air conditioner includes a first auxiliary heating device 81, and the first auxiliary heating device 81 is arranged at the position of the inner circulation air outlet 10b to heat the air flowing out of the inner circulation air outlet 10b, thereby improving the heating effect of the air conditioner.

[0109] In some embodiments, referring to Figure 4 and Figure 6 , the air conditioner includes a second auxiliary heating device 82, and the second electric auxiliary heating device is arranged outside the air inlet 50b so that the air flows into the air inlet 50b through the second electric auxiliary heating device. Thus, the air is heated before entering the air guiding cavity 50a, further improving the heating effect of the air conditioner.

[0110] In some embodiments, referring to Figure 9, the air conditioner includes a duct 90, one end of the duct 90 is communicated with the outer circulation air outlet 10c. The duct 90 guides the air flow discharged from the outer circulation air outlet 10c to the outside. By setting ducts 90 with different lengths, it is convenient to set the casing 10 at a preset installation position and at the same time discharge the air flow in the outer circulation mode to the outside, improving the installation adaptability of the air conditioner.
