[0094] In the embodiment, the flow area of the first air inlet 104 is larger than that of the first air outlet 103, so that the air inflow of the first air duct 10 is increased to ensure the air outflow of the first air duct 10. The small area of the first air outlet 103 enables the first air supply duct 301 and the second air supply duct 302 to be arranged on the two sides of the first air outlet 103, thereby avoiding the size of the air conditioner being too large.

[0095] Optionally, the first heat exchanger and the first fan 101 are arranged in sequence along the flow direction of the airflow in the first air duct 10, or the first fan 101 and the first heat exchanger are arranged in sequence.

[0096] Optionally, the first heat exchanger is arranged at the first air inlet 104, so that the airflow flows into the room after being heated.

[0097] In the case that the first fan 101 is a cross-flow fan, the axial direction of the cross-flow fan is relatively long, and the radial dimension is relatively small. The flow area of the first air inlet 104 is larger than that of the first air outlet 103, and the first heat exchanger and the cross-flow fan are arranged in sequence along the flow direction of the airflow in the first air duct 10, so that the space of the shell 1 can be efficiently utilized, the first air supply duct 301 and the second air supply duct 302 on the two sides of the first air outlet 103 can be arranged with sufficient space, and the size of the indoor unit of the air conditioner is not additionally increased.

[0098] Optionally, the first air inlet 104 is arc-shaped to increase the flow area of the first air inlet 104.

[0099] Optionally, the first heat exchanger is matched with the first air inlet 104, so that the airflow flows through the first heat exchanger before flowing into the room. Specifically, the first heat exchanger is arc-shaped and covers the first air inlet 104, so that the airflow flows through the first heat exchanger before flowing to the first fan 101.

[0100] Optionally, the front surface of the front shell 11 is flush with the front surface of the annular side wall 308.

[0101] In the embodiment, the first air outlet 103 is arranged on the front shell 11, the air outlet 303 of the air supply duct is arranged on the annular side wall 308, and the front surface of the front shell 11 is flush with the front surface of the annular side wall 308, so that the airflow flowing out of the first air outlet 103 and the air outlet 303 of the air supply duct can be mixed in a larger range, and the mixing degree of the airflow flowing out of the first air duct 10 and the second air duct 20 is improved.

[0102] Optionally, as shown in Figure 3 the airflow in the second air duct 20 flows in the vertical direction.

[0103] In the embodiment, the first air duct 10 flows in the rear-to-front direction, and the second air duct 20 flows in the vertical direction, so that the space in the shell 1 is fully utilized, and the size of the shell 1 in other directions is not increased.

[0104] Alternatively, the airflow in the second air duct 20 can also flow in other directions. For example, the second air duct 20 can also extend in the front-to-rear direction or extend in the left-to-right direction or extend obliquely.

[0105] Alternatively, when the airflow in the second air duct 20 flows in the vertical direction, the air supply duct 30 is located above the second air duct 20, and after the airflow enters the second air duct 20 through the second air inlet 204, the airflow flows in the direction from bottom to top.

[0106] In the embodiment, the airflow in the second air duct 20 flows in the direction from bottom to top, and it can be understood that the second fan 201 is located in the lower part of the shell 1, so that the space in the shell 1 is fully utilized, and the size of the air conditioner is not additionally increased, and the space occupied by the air conditioner is saved.

[0107] Alternatively, the second fan 201 and the second heat exchanger 202 are arranged in sequence along the flow direction of the airflow in the second air duct 20, or the second heat exchanger 202 and the second fan 201 are arranged in sequence.

[0108] Alternatively, the second fan 201 can be a centrifugal fan, an axial fan, or a cross-flow fan.

[0109] Alternatively, as shown in Figure 3 , the second air inlet 204 is arranged on the rear shell 12, and after the airflow enters the second air duct 20 through the second air inlet 204, the airflow flows in the direction from bottom to top.

[0110] In the embodiment, the second air inlet 204 is arranged on the rear shell 12, which facilitates the arrangement of the second air inlet 204 and the air inlet of the second air duct 20.

[0111] Alternatively, the shell 1 further comprises an air tunnel 60, one end of the air tunnel 60 communicates with the second fan 201, the other end of the air tunnel 60 communicates with the air supply duct 30, and the second air outlet 203 is arranged at the other end of the air tunnel 60; wherein the number of the second air outlets 203 is the same as and corresponds to the number of the air supply ducts 30, so as to guide the airflow flowing out of the second fan 201 into each air supply duct 30.

[0112] In the embodiment, the air tunnel 60 can guide the air flowing out of the second fan 201 to each air supply duct 30, so that the air volume of each air supply duct 30 is controllable.

[0113] Optionally, the second heat exchanger 202 is located inside the wind tunnel 60. This location saves space in the vertical direction occupied by both the wind tunnel 60 and the second heat exchanger 202, allowing the wind tunnel 60 to simultaneously serve as a duct for airflow and to accommodate the second heat exchanger 202.

[0114] Optionally, the wind tunnel 60 is matched with the second heat exchanger 202 so that the airflow in the wind tunnel 60 can contact the second heat exchanger 202 for heat exchange.

[0115] In this embodiment, the wind tunnel 60 and the second heat exchanger 202 are matched, which means that the shape and size of the wind tunnel 60 are matched with the shape and size of the second heat exchanger 202.

[0116] In one specific embodiment, the second heat exchanger 202 is V-shaped, and the flow area of ​​the wind tunnel 60 gradually increases along the flow direction of the airflow inside the wind tunnel 60.

[0117] The second heat exchanger 202 is V-shaped, which increases the contact area between the airflow and the heat exchanger within the second air duct 20, thereby improving the temperature control effect of the air conditioner. Since the cross-sectional area of ​​the second heat exchanger 202 gradually increases along the airflow direction, the flow area of ​​the wind tunnel 60 also gradually increases along with the airflow flow area within the wind tunnel 60. This arrangement further reduces the space required in the width or thickness direction of the wind tunnel 60 and the second heat exchanger 202. Furthermore, the wind tunnel 60 can guide the airflow more completely through the heat exchanger. Moreover, the gradually increasing flow area of ​​the wind tunnel 60 along the airflow direction results in a larger area on the end face of the wind tunnel 60 facing the air supply duct 30, allowing for the provision of more second air outlets 203, thus providing sufficient second air outlets 203 to connect with multiple air supply ducts 30.

[0118] In another specific embodiment, the second heat exchanger 202 can also be inverted V-shaped, in which case the flow area of ​​the wind tunnel 60 gradually decreases with the flow direction of the airflow inside the wind tunnel 60. Alternatively, when the second heat exchanger 202 has other shapes, the wind tunnel 60 can also be changed accordingly to accommodate the second heat exchanger 202.

[0119] Optionally, such as Figures 13 to 15 As shown, the housing 1 includes a volute 2011, which defines a blower cavity 2012 and an air outlet cavity 2013.

[0126] For example, when the air outlet cavity 2013 extends along the up-down direction, the height of the first mounting portion 20141 and the second mounting portion 20142 corresponding to the first mounting portion 20141 is the same, so that the purification device 2018 can be placed horizontally, avoiding the inclination of the purification device 2018. For another example, when the air outlet cavity 2013 extends along the horizontal direction, the first mounting portion 20141 and the second mounting portion 20142 corresponding to the first mounting portion 20141 are in the same vertical direction, so as to facilitate the installation of the purification device 2018 and save the area of the purification device 2018.

[0127] It should be noted that the first mounting portion 20141 and the second mounting portion 20142 corresponding to the first mounting portion 20141 can also be staggered, which can be set according to the specific structure of the volute 2011, which is not limited here.

[0129] In this embodiment, the third wall segment 2017 increases the space around the first mounting portion 20141, so that when the purification device 2018 is large in size, it can be partially located on the third wall segment 2017. This arrangement makes the volute 2011 applicable to purification devices 2018 of various sizes, and reduces the requirement for the manufacturing precision of the purification device 2018 and the first mounting portion 20141. It saves cost and has strong applicability.

[0130] Optionally, the second wall segment 2016 includes a first sub-wall segment and a second sub-wall segment.

[0133] In the embodiment, the flow area of the air outlet cavity 2013 gradually increases along the flow direction of the airflow, which increases the air outlet amount of the air inlet and reduces the resistance of the airflow at the air outlet. The distance between each first mounting portion 20141 and the corresponding second mounting portion 20142 gradually increases, which means that the distance between each first mounting portion 20141 and the corresponding second mounting portion 20142 gradually increases. In this way, the size of the purification device 2018 mounted on the first mounting portion 20141 and the corresponding second mounting portion 20142 is larger, so as to increase the area of the airflow to be purified and improve the purification efficiency.

[0134] Optionally, the cavity wall of the air outlet cavity 2013 is provided with a taking and placing opening, so as to be suitable for taking and placing the purification device 2018.

[0135] In the embodiment, the taking and placing opening facilitates the taking and placing of the purification device 2018, and the volute 2011 does not need to be disassembled, which facilitates the replacement and maintenance of the purification device 2018.

[0139] In this embodiment, the plurality of purification devices 2018 can purify the airflow flowing out of the fan cavity 2012 multiple times, thereby improving the cleanliness of the airflow flowing out of the air outlet and improving the purification efficiency of the second fan 201.

[0140] Optionally, each purification device 2018 is detachably connected to the corresponding mounting portion 2014.

[0141] In this embodiment, each purification device 2018 is detachably connected to the corresponding mounting portion 2014 of the purification device 2018, thereby facilitating replacement and maintenance of the purification device 2018.

[0142] In actual application, the user can replace different types of purification devices 2018 according to needs, thereby purifying different substances in the air.

[0143] Each purification device 2018 and the corresponding mounting portion 2014 of the purification device 2018 can be connected by buckling or screwing, etc.

[0144] Optionally, each purification device 2018 is placed in the corresponding mounting portion 2014.

[0145] In this embodiment, each purification device 2018 is placed in the corresponding mounting portion 2014 of the purification device 2018, which can be understood as that each purification device 2018 is supported on the corresponding mounting portion 2014 of the purification device 2018, without the need for connection. In this way, the purification device 2018 is convenient to take, and replacement and maintenance of the purification device 2018 are facilitated.

[0146] For example, when the volute 2011 is arranged along the up-down direction, the mounting portions 2014 all extend along the horizontal direction, and the purification device 2018 can be placed on the mounting portion 2014, thereby achieving installation of the purification device 2018.

[0147] Optionally, the plurality of purification devices 2018 installed in the volute 2011 can be the same or different. For example, when the airflow blown by the second fan 201 contains a high content of a certain harmful substance, two or more purification devices 2018 for purifying the substance can be arranged. If the airflow blown by the second fan 201 contains multiple harmful substances, multiple purification devices 2018 for purifying the harmful substances can be arranged.

[0148] Specifically, the plurality of purification devices 2018 can purify haze, formaldehyde, allergy, bacteria, odor, mold and other harmful substances. One of the above-mentioned multiple purification devices 2018 can be arranged in the volute 2011, or multiple purification devices 2018 can be arranged.

That is, the user can freely combine the purification devices 2018, thereby fully ensuring the cleanliness of the airflow flowing into the room.

[0149] Optionally, as shown in Figure 10 the outer wall surface of the air duct 60 and the outer wall surface of the volute 2011 are connected through the support rod 601.

[0150] In this embodiment, the support rod 601 serves to connect the air duct 60 and the volute 2011, and increases the connection stability of the second air fan 201 and the air duct 60. The separation of the air duct 60 and the second air fan 201 caused by moving or long-term use is avoided.

[0153] Optionally, in the case where the flow area of the air duct 60 gradually increases along the flow direction of the airflow, the outer wall surface of the air duct 60 is inwardly recessed to form a mounting groove, and the support rod 601 is located in the mounting groove, so as to facilitate the extension of the support rod 601 in the up-down direction.

[0154] Optionally, the support rod 601 is detachably connected with the outer wall surface of the air duct 60, such as a bolt, a buckle, etc. The support rod 601 is detachably connected with the outer surface of the volute 2011, such as a bolt, a buckle, etc.

[0155] In the case where the flow area of the air duct 60 gradually increases along the flow direction of the airflow, the outer surface of the volute 2011 is outwardly protruded to form a connecting portion, so as to be connected with the support rod 601.

[0156] Optionally, the number of the support rods 601 is multiple, and the multiple support rods 601 can further increase the connection stability of the second air fan 201 and the air duct 60.

[0157] In one specific embodiment, the multiple support rods 601 include a first support rod and a second support rod, and the first support rod and the second support rod are arranged along the width direction of the air conditioner. In this way, the support rod 601 will not block the air inlet and outlet of the first air fan 101.

[0158] Optionally, the housing 1 also includes an outer cover, inside which the second fan 201 and the wind tunnel 60 are located. The outer cover protects the second fan 201 and the second heat exchanger 202, preventing dust from the external environment from entering the second fan 201 or the second heat exchanger 202. At the same time, the outer cover also enhances the aesthetic appearance of the air conditioner.

[0159] Optionally, the outer cover includes a front shell 11 and a rear shell 12, with the second air inlet 204 located on the rear shell 12 to facilitate air intake of the second air duct 20.

[0160] Optionally, the outer cover also includes a limiting part. When the support rod 601 is connected to the outer surface of the volute 2011 and the outer surface of the wind tunnel 60, the limiting part limits the support rod 601 to the outside, so as to prevent the support rod 601 from falling off when the connection between the support rod 601 and the wind tunnel 60 or the volute 2011 becomes loose.

[0161] Optionally, the first air duct 10 is located above the second air duct 20 to make the structure of the air conditioner more compact and the layout more reasonable.

[0162] In one specific embodiment, the first fan 101 and the first heat exchanger are both higher than the second fan 201 and the second heat exchanger 202.

[0163] In this embodiment, the first fan 101 and the first heat exchanger are arranged vertically along the second fan 201 and the second heat exchanger 202, which can make full use of the space in the height direction of the shell 1 and save space in the width and thickness of the shell 1.

[0164] Optionally, the height of the first air inlet 104 is greater than the height of the second air inlet 204.

[0165] In this embodiment, the height of the first air inlet 104 is greater than the height of the second air inlet 204, which can reduce the flow path of the airflow in the first air duct 10 and the airflow in the second air duct 20, and avoid the airflow of the first air duct 10 and the airflow of the second air duct 20 interfering with each other.

[0166] Optionally, the first air outlet 103 and the first air inlet 104 are arranged opposite to each other.

[0167] In this embodiment, the first air outlet 103 and the first air inlet 104 are arranged opposite to each other, which further shortens the flow path of the airflow in the first air duct 10, thereby reducing the loss of airflow in the first air duct 10.

[0168] Optionally, such as Figure 12 As shown, the indoor unit also includes a drive device 50, which is driven to each air duct 30 and can drive each air duct 30 to move around its axis to adjust the direction of the air outlet 303 of each air duct.

[0169] In the embodiment, each air supply duct 30 is rotatable, the air supply direction of each air supply duct 30 can be adjusted, and the air supply direction of the air conditioner can be adjusted. In addition, the air flow from the air outlet 303 of the air supply duct and the air flow from the first air outlet 103 can be mixed, and the air supply direction and air volume of the first air duct 10 can be adjusted by using vector adjustment technology.

[0170] Optionally, the number of the driving devices 50 is plural, and the number of the driving devices 50 is the same as that of the air supply ducts 30 and corresponds to the air supply ducts 30 one by one. In the embodiment, each air supply duct 30 can be independently controlled by the corresponding driving device 50, and the independent rotation of each air supply duct 30 is realized.

[0171] Optionally, the plural air supply ducts 30 can rotate in the same direction or in different directions.

[0172] Optionally, the indoor unit further comprises a second detection device for detecting information of a user; the controller is electrically connected with the second detection device and the driving device 50, and the controller can receive the information of the user and control the driving device 50 to move according to the information of the user.

[0173] In the embodiment, the indoor unit of the air conditioner collects the information of the user by using the second detection device, and then controls the driving device 50 to rotate according to the information of the user, so that the air supply of the air conditioner can reach the best comfort level of the user.

[0174] Optionally, the air supply duct 30 is rotatable between a maximum wide-angle air supply position and a power-off position, wherein when the air supply duct 30 rotates to the maximum wide-angle air supply position, the air outlet 303 of the air supply duct faces away from the first air duct 10; when the air supply duct 30 rotates to the power-off position, the air outlet 303 of the air supply duct faces the first air duct 10. When the indoor unit of the air conditioner is turned on, the air supply duct 30 can rotate from the power-off position to the maximum wide-angle air supply position towards the front side.

[0175] In the embodiment, when the air supply duct 30 is at the maximum wide-angle air supply position, the air outlet 303 of the air supply duct faces away from the first air duct 10, and the air supply is dispersed, which is suitable for the case of crowd dispersion. When the air supply duct 30 is at the power-off position, the air outlet 303 of the air supply duct faces the first air duct 10. Both the first air supply duct 301 and the second air supply duct 302 can rotate between the maximum wide-angle air supply position and the power-off position, and various air supply forms can be realized, thereby increasing the air supply diversity of the air conditioner.

[0176] Optionally, the rotation angle range of each air supply duct 30 is 0° to 180°. When the rotation angle of the air supply duct 30 is 0°, the air supply duct 30 is at the power-off position; when the rotation angle of the air supply duct 30 is 180°, the air supply duct 30 is at the maximum wide-angle air supply position.

[0177] The first air outlet 103 blows air forward, and the first air supply duct 301 and the second air supply duct 302 are divided into two parts located on the two sides of the first air outlet 103. The various air outlet forms of the air conditioner are described as follows:

[0178] When the second fan 201 is in the shutdown state and no air flow flows in the second air duct 20, the first air supply duct 301 and the second air supply duct 302 are both located in the shutdown position.

[0179] When the user expects the air conditioner to blow directly, the air outlet of the first air supply duct 301, the air outlet of the second air supply duct 302, and the first air outlet 103 all face forward, so that the air outlet of the air conditioner faces forward and the air volume of the air conditioner can be ensured.

[0180] When the indoor space is large and the air supply distance is far, only the first air outlet 103 or the air outlet 303 of the air supply duct cannot send air to the target position, the air outlet of the first air supply duct 301 and the air outlet of the second air supply duct 302 are both deviated to the first air outlet 103, thereby forming an aggregated long-distance direct blowing mode. The air supply effect of long distance can be achieved. For example, the air conditioner is placed in the living room, and the user is dining in the dining room, and the above mode can be used for air outlet.

[0181] When the user does not need direct blowing, the air outlet of the first air supply duct 301 and the air outlet of the second air supply duct 302 can be controlled to deviate from the position of the user, and the air flow flowing out of the first air outlet 103 can be guided by the air flow flowing out of the air outlet of the first air supply duct 301 and the air outlet of the second air supply duct 302. The air outlet direction of the first air supply duct 301 and the second air supply duct 302 is consistent. In this embodiment, the wind direction of the intermediate air duct can be adjusted by vector adjustment technology.

[0182] When the user needs to quickly adjust the indoor temperature, the air outlet of the first air supply duct 301 and the air outlet of the second air supply duct 302 are deviated from the first air outlet 103, thereby increasing the range of the air outlet of the air conditioner, and the air conditioner can be widely supplied, thereby achieving the purpose of quickly adjusting the indoor temperature.

[0183] When the indoor personnel are relatively dispersed, the first air supply duct 301 and the second air supply duct 302 are both rotated to the maximum wide-angle air outlet position, the first air outlet 103 blows air forward, and the wall-attached surrounding air supply can be formed. The air supply is realized without blowing people, so that the indoor personnel can all feel the air outlet of the air conditioner.

[0184] When the indoor personnel include both users who do not like direct blowing of the air conditioner and users who like direct blowing, the air volume of the first air supply duct 301 and the second air supply duct 302 can be controlled to be different, the air supply duct 30 facing the user who likes direct blowing can be in a large air volume mode, and the air supply duct 30 facing the user who does not like direct blowing can be in a small air volume mode. Meanwhile, the first air outlet 103 normally blows air, which can meet the needs of multiple personnel and also ensure rapid temperature adjustment.

[0185] When the indoor temperature is generally high or generally low, the air conditioner does not need to start with high rotation speed and large air volume operation, and the first fan 101 and the second fan 201 can be selected to operate at low rotation speed, or only one of the first heat exchanger or the second heat exchanger 202 is opened, and the first fan 101 and the second fan 201 normally operate. While ensuring temperature adjustment, the energy consumption of the air conditioner is reduced.

[0186] Optionally, as shown in Figure 2 and Figure 11 , the shell 1 includes a side wall 40 located between the first air duct 10 and the air supply duct 30, wherein the side wall 40 and the air supply duct 30 together define a third air duct 405, the third air duct 405 is provided with a third air inlet 406 and a third air outlet 407, the third air inlet 406 is in communication with the outside, and the third air outlet 407 is located between the first air outlet 103 and the air outlet 303 of the air supply duct; wherein when the first air outlet 103 and / or the air outlet 303 of the air supply duct blow air, a negative pressure is formed at the third air outlet 407, the ambient wind flows into the third air outlet 407 through the third air duct 405, and the ambient wind mixes with the airflow flowing out of the first air outlet 103 and / or the air outlet 303 of the air supply duct and then flows out.

[0187] In this embodiment, the third air duct 405 can guide the ambient wind to flow to the first air outlet 103 and / or the air outlet 303 of the air supply duct, mix with the airflow flowing out of the first air outlet 103 and / or the air outlet 303 of the air supply duct, and form uniform wind. The uniform wind is more gentle, the temperature is more suitable, and the comfort of the indoor user is increased. In particular, when the air conditioner cools, the uniform wind is cool but not cold, which can avoid blowing cold wind to the user and avoid the user suffering from air conditioner disease.

[0188] Optionally, the side wall 40 matches the outer wall surface of the air supply duct 30.

[0189] In the embodiment, the side wall 40 matches the outer wall surface of the air supply duct 30, which means that the side wall 40 has the same or similar shape as the outer wall surface of the air supply duct 30. The matching of the side wall 40 and the outer wall surface of the air supply duct 30 makes the flow area of the third air duct 405 more uniform and the flow path of the third air duct 405 longer. In this way, the air flow resistance in the third air duct 405 is avoided to be too large, or the air supply of the environment is avoided to be insufficient due to the short flow path of the third air duct 405. In this way, the air volume of the environment air flowing out of the third air outlet 407 is ensured, and the mixing effect of the mixed air of the air conditioner is improved.

[0190] Optionally, the side wall 40 is arc-shaped, and the arc-shaped opening faces the air supply duct 30.

[0191] In the embodiment, the side wall 40 is arc-shaped, and the arc-shaped opening faces the air supply duct 30, so that the side wall 40 matches the shape of the air supply duct 30, and the third air duct 405 is arranged in an arc shape, so that the flow area of the third air duct 405 is more uniform, and the flow speed of the air flow in the third air duct 405 is ensured.

[0192] Optionally, the third air outlet 407 matches the air outlet 303 of the air supply duct. It can be understood that the third air outlet 407 and the air outlet 303 of the air supply duct have the same or similar shape, size, and extension direction.

[0194] Optionally, the extension direction of the third air outlet 407 is consistent with the extension direction of the air outlet 303 of the air supply duct. In the embodiment, the extension direction of the third air outlet 407 is consistent with the extension direction of the air outlet 303 of the air supply duct, so that the communication area of the third air outlet 407 and the air outlet 303 of the air supply duct is large, and the outflow area of the mixed air of the third air outlet 407 and the air outlet 303 of the air supply duct is increased.

[0195] Optionally, when the air outlet 303 of the air supply duct extends along the length direction of the air supply duct 30, the third air outlet 407 also extends along the length direction of the air supply duct 30, so that the communication area of the air outlet 303 of the air supply duct and the third air outlet 407 is larger.

[0196] The first air fan 101 is a cross-flow fan, and when the first air outlet 103 extends along the length direction of the cross-flow fan, the third air outlet 407 and the air outlet 303 of the air supply duct also extend along the length direction of the cross-flow fan.

[0197] Optionally, the side wall 40 is connected between the front shell 11 and the rear shell 12, and the air flow in the third air duct 405 flows in a direction from rear to front.

[0198] In this embodiment, the side wall 40 is connected between the front shell 11 and the rear shell 12, so that the side wall 40 can be stably connected to the air conditioner. Moreover, the air flow in the third air duct 405 can also flow in a direction from rear to front, so as to make full use of the space between the first air duct 10 and the air supply cylinder 30. The air inlet amount of the third air inlet 406 is ensured, while the resistance of the air flow in the third air duct 405 is reduced. The third air duct 405 flows in a direction from rear to front, the distance is short, the loss of the air flow is small, and the air flow can flow into the third air outlet 407 smoothly without overcoming the resistance such as gravity.

[0199] Optionally, the flow area of the third air outlet 407 is larger than the flow area of the third air inlet 406.

[0200] In this embodiment, the flow area of the third air outlet 407 is large, so that the space for mixing the air flow at the third air outlet 407 and the air flow flowing out of the first air outlet 103 is increased, and then the mixing time of the ambient air and the heat exchange air is increased, and the mixing effect of the mixed air is improved.

[0201] Optionally, the side wall 40 comprises a body and a flow guide plate, the flow guide plate is connected to the wall surface of the body facing the air supply cylinder 30, the flow guide plate comprises a first flow guide plate and a second flow guide plate connected in sequence, the first flow guide plate and the second flow guide plate are arranged in sequence along the flow direction of the air flow in the third air duct 405, wherein the first flow guide plate is matched with the outer wall surface of the air supply cylinder 30, and the second flow guide plate is inclined toward the first air outlet 103 along the flow direction of the air flow in the third air duct 405.

[0202] In this embodiment, the second flow guide plate is inclined toward the first air outlet 103 along the flow direction of the air flow in the third air duct 405, and the outer wall surface of the air supply cylinder 30 comprises an annular wall surface, so that the flow area of the part of the third air duct 405 defined by the air supply cylinder 30 and the second flow guide plate gradually increases. Finally, the flow area of the third air outlet 407 is larger than the flow area of the third air inlet 406.

[0203] Optionally, the number of the side wall 40 is the same as and corresponds to the number of the air supply cylinder 30.

[0204] In this embodiment, each air supply cylinder 30 is correspondingly provided with a side wall 40, so that the number of the third air duct 405 is the same as the number of the air supply cylinder 30, and the air inlet amount of the ambient air of the air conditioner is increased.

[0205] Optionally, the plurality of side walls 40 comprises a first side wall 401 corresponding to the first air supply duct 301 and a second side wall 402 corresponding to the second air supply duct 302, and the first side wall 401 and the second side wall 402 are located between the first air supply duct 301 and the second air supply duct 302. Specifically, the first side wall 401 and the second side wall 402 are located on both sides of the first air duct 10, respectively.

[0206] The plurality of third air ducts 405 comprises a first sub-air duct and a second sub-air duct, the first sub-air duct is located between the first side wall 401 and the first air supply duct 301, and the second sub-air duct is located between the second side wall 402 and the second air supply duct 302.

[0207] Optionally, the first side wall 401, the second side wall 402, the front shell 11 and the rear shell 12 jointly enclose a containing cavity, and the first air duct 10 is located in the containing cavity.

[0208] In the embodiment, the structure and layout of the first air duct 10, the air supply duct 30 and the side wall 40 are reasonable, which can realize the air outlet of the three air ducts without increasing the size of the air conditioner, and improve the application range of the air conditioner.

[0209] Optionally, as shown in Figure 2 The longitudinal cross-sectional area of the containing cavity gradually decreases in the direction from back to front.

[0210] The longitudinal cross-sectional area of the containing cavity gradually decreases in the direction from back to front, so that there is enough space in the containing cavity to place the first fan 101, the first heat exchanger and the volute of the first fan 101, and the cross-sectional area of the containing cavity close to the front shell 11 gradually decreases, which can avoid the air supply duct 30 and ensure that the air supply duct 30 has enough space for installation. By such arrangement, the size of the air conditioner is not increased, and the function of the air conditioner can be increased.

[0211] Optionally, the cross section of the air supply duct 30 is oval.

[0212] In the embodiment, the air supply duct 30 can rotate around its axis, and the cross section of the air supply duct 30 is oval, so that the distance between the outer wall surface of the air supply duct 30 and the side wall 40 can be changed during the rotation of the air supply duct 30, and the flow area of the third air duct 405 can be adjusted. By such arrangement, the air outlet of the third air duct 405 can be adjusted, and the diversity of the air conditioner is increased.

[0213] Optionally, the front surface of the front shell 11 protrudes from the front surface of the annular side wall 308.

[0214] In the embodiment, the airflow flowing out of the first air outlet 103 can better guide the airflow in the third air duct 405 to flow out through the third air outlet 407, and at the same time, the airflow blown out by the air supply duct 30 on both sides can also better adjust the direction of the airflow flowing out of the first air duct 10.

[0215] Optionally, when the air supply duct 30 is in the maximum wide-angle air outlet position or the off position, the outer wall surface of the air supply duct 30 abuts against the side wall 40, and the third air duct 405 is disconnected.

[0216] Optionally, when the air supply duct 30 rotates between the maximum wide-angle air outlet position and the off position, there is a gap between the outer wall surface of the air supply duct 30 and the side wall 40, and as the air supply duct 30 rotates, the flow area of the third air duct 405 also changes, and the air outlet amount of the third air outlet 407 also changes.

[0217] Taking the first air outlet 103 as an example, the first air supply duct 301 and the second air supply duct 302 are divided into two parts located on both sides of the first air outlet 103 and have the third air duct 405, and the various air outlet forms of the air conditioner are described:

[0218] When the user expects the air conditioner to blow directly, the air outlets of the first air supply duct 301 and the second air supply duct 302 and the first air outlet 103 are all forward, so that the air outlets of the air conditioner are all forward. At the same time, the airflows flowing out of the air outlets of the first air supply duct 301, the second air supply duct 302 and the first air outlet 103 form negative pressure at the third air outlet 407, and the ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and the ambient wind mixes with the air of the second air duct 20 and the first air duct 10 and then flows out, achieving uniform air outlet of the air conditioner and ensuring the air outlet amount.

[0219] When the indoor crowd does not like direct blowing of the air conditioner, but needs to quickly adjust the ambient temperature to the desired position, the air outlet amounts of the first air supply duct 301 and the second air supply duct 302 can be controlled to be the same, and the first air supply duct 301 and the second air supply duct 302 are adjusted to not be directed towards the user, and the air outlet of the first air outlet 103 can not be directed towards the user under the action of the vector adjustment. At the same time, the airflows flowing out of the air outlets of the first air supply duct 301, the second air supply duct 302 and the first air outlet 103 form negative pressure at the third air outlet 407, and the ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and the ambient wind mixes with the air of the second air duct 20 and the first air duct 10 and then flows out. Finally, uniform air outlet, wind avoidance, large air outlet amount and non-direct blowing are achieved.

[0220] When the indoor space is large and the air supply distance is far, the air cannot be sent to the target position only by the first air outlet 103 or the air outlet 303 of the air supply duct. The air outlets of the first air supply duct 301 and the second air supply duct 302 are both inclined to the first air outlet 103, thereby forming an aggregated long-distance direct blowing mode. At the same time, the air flows out of the air outlet of the first air supply duct 301, the air outlet of the second air supply duct 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. The air conditioner can achieve uniform air outflow and long-distance air supply effect.

[0221] When the user needs to quickly adjust the indoor temperature, the air outlets of the first air supply duct 301 and the second air supply duct 302 are both inclined to the first air outlet 103. At the same time, the air flows out of the air outlet of the first air supply duct 301, the air outlet of the second air supply duct 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. The air conditioner can achieve uniform air outflow and long-distance air supply effect.

[0222] When the indoor personnel include both users who do not like direct blowing of the air conditioner and users who like direct blowing, the air supply amount of the first air supply duct 301 and the second air supply duct 302 can be controlled to be different. The air supply duct 30 facing the user who likes direct blowing can be in a large air volume mode, and the air supply duct 30 facing the user who does not like direct blowing can be in a small air volume mode. At the same time, the first air outlet 103 normally blows air. The air flows out of the air outlet of the first air supply duct 301, the air outlet of the second air supply duct 302 and the first air outlet 103, so that a negative pressure is formed at the third air outlet 407. The ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and then flows out after mixing with the air of the second air duct 20 and the first air duct 10. The air conditioner can achieve uniform air outflow and can also ensure quick temperature adjustment while meeting the needs of multiple personnel.

[0223] When the indoor temperature is generally high or generally low, the air conditioner does not need to run at high speed and large air volume at the beginning, and can select low speed operation of the first fan 101 and the second fan 201, or only one of the first heat exchanger or the second heat exchanger 202 is opened, and the first fan 101 and the second fan 201 are normally operated. The air flow out of the first air outlet 103, the air outlet of the first air supply duct 301 and the air outlet of the second air supply duct 302 forms a negative pressure at the third air outlet 407, and the ambient wind flows to the third air outlet 407 through the third air inlet 406 and the third air duct 405 under the action of the negative pressure at the third air outlet 407, and the ambient wind and the air of the second air duct 20 and the first air duct 10 are mixed and flow out. While ensuring the adjustment of the temperature, the air conditioner realizes uniform air outlet and reduces the energy consumption of the air conditioner.

[0224] In the embodiment, the first air duct 10 and the second air duct 20 can flow out heat exchange air or ambient air by controlling the opening and closing of the corresponding heat exchanger, wherein one of the first air duct 10 and the second air duct 20 flows out ambient air driven by the fan, and the mixed air of the ambient air and the heat exchange air flowing out of the other of the first air duct 10 and the second air duct 20 can be called active uniform air. The mixed air of the ambient air flowing out of the third air outlet 407 and the heat exchange air flowing out of the first air outlet 103 or the air outlet 303 of the air supply duct under the condition that the third air outlet 407 forms a negative pressure can be called passive uniform air.

[0225] The indoor unit of the air conditioner of the embodiment can realize wide-angle air supply (by rotating the air supply duct 30), uniform air outlet mode, and aggregation air supply, and the uniform air outlet mode can further include passive uniform air, active uniform air, mixed uniform air, and mixed uniform air, that is, a plurality of air outlet modes such as active and passive uniform air, thereby increasing the air outlet mode of the air conditioner and meeting the use requirements of the user for various air outlets.

[0226] Optionally, the air conditioner can be a cabinet type air conditioner, a wall-mounted air conditioner, etc.

[0227] Optionally, as shown in Figure 7 and Figure 8 , the shell 305 of the air supply duct 30 defines an air outlet air duct 306, the air outlet air duct 306 communicates the air inlet of the air supply duct 30 and the air outlet 303 of the air supply duct, and the air supply duct 30 further comprises a partition plate 307, the partition plate 307 is located in the air outlet air duct 306 and separates the air outlet air duct 306 into a plurality of sub-air outlet air ducts 3061, wherein the plurality of sub-air outlet air ducts 3061 are in communication with the air inlet of the air supply duct 30 and the air outlet 303 of the air supply duct.

[0228] In the embodiment, the partition plate 307 divides the air outlet air duct 306 into multiple sub-air outlet air ducts 3061. Since the multiple sub-air outlet air ducts 3061 are all in communication with the air inlet of the air supply duct 30 and the air outlet 303 of the air supply duct, each sub-air outlet air duct 3061 can guide the airflow flowing into the air inlet of the air supply duct 30 to the air outlet 303 of the air supply duct. The air supply amount of each part of the air outlet 303 of the air supply duct 30 can be adjusted through the multiple sub-air outlet air ducts 3061.

[0229] Optionally, the partition plate 307 is arranged on the inner wall surface of the air outlet air duct 306 and located at the air outlet 303 of the air supply duct.

[0230] In the embodiment, the partition plate 307 is located at the air outlet 303 of the air supply duct, which can more accurately guide the airflow of the air inlet of the air supply duct 30 to the air outlet 303 of the air supply duct, so that the air supply of the air outlet 303 of the air supply duct is easy to adjust.

[0231] Optionally, the air inlet of the air supply duct 30 is arranged at the first end portion 3081 and / or the second end portion 3082, the partition plate 307 comprises a first connecting section 3071 and a second connecting section 3072, the first connecting section 3071 extends along the length direction of the air supply duct 30, one end of the first connecting section 3071 is located in the air outlet air duct 306, the first connecting section 3071 is located at the air outlet 303 of the air supply duct, and there is a gap between the inner wall surface of the air supply duct 30 opposite to the air outlet 303 of the air supply duct, so as to facilitate the airflow; the second connecting section 3072 extends along the radial direction of the air supply duct 30, one end of the second connecting section 3072 is connected with the other end of the first connecting section 3071, and the other end of the second connecting section 3072 is located at the air outlet 303 of the air supply duct; wherein, the first connecting section 3071 and the second connecting section 3072 are sequentially arranged along the flow direction of the airflow in the air outlet air duct 306.

[0232] In the embodiment, the air inlet of the air supply duct 30 is arranged at the first end portion 3081 and / or the second end portion 3082, the air outlet 303 of the air supply duct is arranged at the annular side wall 308, and the airflow needs to flow along the length direction of the air supply duct 30 first and then flow along the radial direction of the air supply duct 30. The first connecting section 3071 is used to guide the airflow at the air inlet of the air supply duct 30 to flow to the second connecting section 3072, and the second connecting section 3072 is used to guide the airflow at the first connecting section 3071 to flow to the air outlet 303 of the air supply duct. The first connecting section 3071 and the second connecting section 3072 can more effectively guide the airflow of the air inlet of the air supply duct 30 to the air outlet 303 of the air supply duct.

[0233] Optionally, the partition plate 307 further comprises a third connecting section 3073, one end of the third connecting section 3073 is connected with the other end of the first connecting section 3071, and the other end of the third connecting section 3073 is connected with one end of the second connecting section 3072; wherein the second connecting section 3072 is in an arc shape, and the opening of the arc shape faces the air outlet 303 of the air supply duct.

[0234] In the embodiment, the third connecting section 3073 can guide the airflow flowing to the second connecting section 3072 through the first connecting section 3071. The third connecting section 3073 is in an arc shape, which can make the flow resistance of the airflow smaller and reduce the loss in the flow process of the airflow.

[0235] Optionally, the number of the partition plates 307 is multiple, and the multiple partition plates 307 are sequentially and spacedly arranged along the length direction of the air supply duct 30.

[0236] In the embodiment, the multiple partition plates 307 are sequentially and spacedly arranged along the length direction of the air supply duct 30, which can adjust the air volume of each part of the air outlet 303 of the air supply duct 30 along the length direction.

[0237] Optionally, the multiple partition plates 307 are sequentially and spacedly arranged along the length direction of the air supply duct 30, and the spacing between the multiple partition plates 307 is different in order to ensure that the air outlet of each sub-air outlet air duct 3061 is relatively uniform. For example, along the flow direction of the airflow in the air outlet air duct 306, the distance between the first connecting section 3071 of the multiple partition plates 307 and the air outlet 303 of the air supply duct gradually increases.

[0238] In the embodiment, the distance between the first connecting section 3071 of the multiple partition plates 307 and the air outlet 303 of the air supply duct gradually increases, which can be understood as that the length of the second connecting section 3072 along the radial direction of the air supply duct 30 gradually increases. In this way, along the flow direction of the airflow in the air outlet air duct 306, the distance between the first connecting section 3071 and the inner wall surface of the air outlet air duct 306 corresponding to the air outlet 303 of the air supply duct gradually decreases, that is, along the flow direction of the airflow in the air outlet air duct 306, the flow area of each sub-air outlet air duct 3061 and the air inlet of the air supply duct 30 along the radial direction of the air supply duct 30 gradually increases.

[0239] The shorter the distance from the air inlet of the air supply duct 30 to the air outlet 306, the faster the air speed, so the sub-air outlet duct 3061 close to the air inlet of the air supply duct 30 has a smaller radial communication area with the air inlet of the air supply duct 30, which can guide enough air to flow out. At the same time, the first connecting section 3071 close to the air inlet of the air supply duct 30 has a larger distance from the air outlet 303 of the air supply duct 30, which can make more air flow into the sub-air outlet duct 3061 away from the air inlet of the air supply duct 30. Through the arrangement of the partition plate 307 in this embodiment, the air outlet of each sub-air outlet duct 3061 is more uniform, and the uniform air outlet of the air conditioner can be realized.

[0240] Optionally, as shown in Figure 12 , the outer wall surface of the shell 305 is provided with a rotating part, which is suitable for driving connection with the driving device 50, and the driving device 50 can drive the air supply duct 30 to rotate around its axis.

[0241] In this embodiment, the rotating part is used to cooperate with the driving device 50, which can drive the air supply duct 30 to rotate, thereby changing the air outlet direction of the air outlet 303 of the air supply duct, increasing the air outlet range of the air conditioner, and diversifying the air outlet of the air conditioner.

[0242] Optionally, the rotating part is arranged at the first end 3081 and / or the second end 3082, which facilitates the connection of the driving device 50 with the rotating part and the arrangement of the driving device 50.

[0243] Optionally, as shown in Figure 12 , Figure 21 and Figure 22 , the rotating part includes a rack 501, which is arranged on the outer wall surface of the annular side wall 308 and extends along the circumference of the outer wall surface of the annular side wall 308. The driving device 50 includes a motor and a gear 502, one end of the gear 502 is connected with the output shaft of the motor, and the other end of the gear 502 is engaged with the rack 501.
