Description

Technical Field

[0001] The present application relates to, but is not limited to, the technical field of air conditioners, and specifically refers to an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] To achieve the fresh air or exhaust air function in the existing ducted air conditioner, it is necessary to additionally add a fresh air module with a fan on the basis of the original unit. Since an additional fan is required, the size of the unit is large, the space required for installing the unit is large, the cost of the unit is high, and at the same time, the noise value becomes larger, resulting in a poor user experience. In addition, due to the limited structural size of the fresh air module, the fresh air volume is not high (currently, the maximum fresh air volume of the ducted air conditioner on the market is 210m 3 / h). Summary of the Invention

[0003] An embodiment of the present application provides an indoor unit of an air conditioner, including:

[0004] A housing having a fan chamber, a heat exchange chamber, and a first chamber. The fan chamber and the heat exchange chamber are arranged in parallel, the first chamber is disposed on the same side of the fan chamber and the heat exchange chamber and extends from the fan chamber to the heat exchange chamber. The fan chamber includes a first fan chamber close to the first chamber. The first fan chamber has a first air supply opening and an openable and closable first air return opening. The first chamber has a suction and exhaust air opening communicating with the outside, and the first chamber and the first fan chamber are communicated through a first communication channel. The heat exchange chamber has an air outlet;

[0005] A first fan disposed in the first fan chamber;

[0006] A first control valve configured to control the on-off of the first communication channel; and

[0007] An exhaust control valve configured to control the first air supply opening to be communicable with any one of the heat exchange chamber and the first chamber and disconnectable from the other of the heat exchange chamber and the first chamber.

[0008] An embodiment of the present application further provides an air conditioner including the indoor unit of the air conditioner according to any one of the above embodiments.

[0009] For the indoor unit of the air conditioner in the embodiment of the present application, by adding a first chamber, controlling the on-off of the first chamber and the first fan chamber, and combining with the original first fan for the internal circulation mode, the indoor unit of the air conditioner additionally has a fresh air mode and an exhaust air mode. When the fresh air mode is turned on, the first fan only does work on the fresh air coming in from the outside, and the air volume generated by it is the fresh air volume. Since the original first fan already has enough space to be placed in the housing, the air volume is relatively large, so that the fresh air volume in the fresh air mode is larger than that of the ducted air conditioner with the fresh air function in the prior art.

[0010] Since the original first fan is directly used as the fresh air fan for introducing outdoor fresh air into the room without the need to additionally add a fan, the noise of the entire indoor unit of the air conditioner is lower than that of the existing ducted air conditioner with a fresh air function.

[0011] In addition, since there is no need to newly add a fresh air module with a fan, the overall size of the unit is smaller than that of the existing ducted air conditioner.

[0012] Therefore, the indoor unit of the air conditioner in the embodiment of the present application realizes the functions of introducing fresh air from the outside and exhausting the turbid air inside the room. Without the need to additionally add a fan on the basis of the original basic model, it has low noise; the unit structure is small in size, low in cost, has a large available installation space, and is more convenient to install.

Detailed implementation manners

[0025] The principles and features of the present application will be described below with reference to the attached drawings. The examples given are only for explaining the present application and are not intended to limit the scope of the present application.

[0026] As Figures 1 - 7b shown, an embodiment of the present application provides an indoor unit of an air conditioner, which includes a housing 1, a first fan 21, a first control valve 31 and an exhaust control valve.

[0027] The housing 1 has a fan chamber, a heat exchange chamber 12 and a first chamber 13. The fan chamber and the heat exchange chamber 12 are arranged in parallel. The first chamber 13 is arranged on the same side of the fan chamber and the heat exchange chamber 12 and extends from the fan chamber to the heat exchange chamber 12. The fan chamber includes a first fan chamber 11 close to the first chamber 13. The first fan chamber 11 has a first air supply opening 111 and an openable and closable first air return opening 112. The first air return opening 112 of the first fan chamber 11 can communicate with the room so that indoor air can enter the first fan chamber 11 through the first air return opening 112, and the air in the first fan chamber 11 can be discharged from the first air supply opening 111. The first chamber 13 has an air suction and discharge opening 133 communicating with the outside, and the first chamber 13 and the first fan chamber 11 are connected through a first communication channel 141. The heat exchange chamber 12 has an air outlet 18.

[0028] The first fan 21 is arranged in the first fan chamber 11.

[0029] The first control valve 31 is configured to control the on / off of the first communication passage 141.

[0030] The exhaust air control valve is configured to control the first air supply port 111 to be communicable with any one of the heat exchange chamber 12 and the first chamber 13, and to be disconnected from the other of the heat exchange chamber 12 and the first chamber 13. That is, the exhaust air control valve can control the first air supply port 111 to be communicable with the heat exchange chamber 12 and disconnected from the first chamber 13; the exhaust air control valve can also control the first air supply port 111 to be communicable with the first chamber 13 and disconnected from the heat exchange chamber 12.

[0031] In the indoor unit of the air conditioner, in addition to the fan chamber and the heat exchange chamber 12, the housing 1 further has a first chamber 13. The first chamber 13 is located on the same side of the juxtaposed fan chamber and heat exchange chamber 12, and the first chamber 13 can extend from the side close to the fan chamber to the side close to the heat exchange chamber 12. Among them, both the fan chamber and the heat exchange chamber 12 can extend along the length direction of the housing 1, and the fan chamber and the heat exchange chamber 12 can be juxtaposed along the width direction of the housing 1. The first chamber 13 can be arranged on one side in the length direction of the fan chamber and the heat exchange chamber 12, and the first chamber 13 can extend from the side close to the fan chamber to the side close to the heat exchange chamber 12 along the width direction.

[0032] The first chamber 13 has a suction and exhaust air port 133 communicating with the outside. On the one hand, the first chamber 13 communicates with the first fan chamber 11 through the first communication passage 141, and the on / off of the first communication passage 141 is controlled by the first control valve 31; on the other hand, the first chamber 13 also realizes the communication or disconnection with the first air supply port 111 of the first fan chamber 11 through the exhaust air control valve, and the first air supply port 111 of the first fan chamber 11 can also realize the communication or disconnection with the heat exchange chamber 12 through the exhaust air control valve. A first fan 21 is provided in the first fan chamber 11. When the first fan 21 operates, air can enter the first fan chamber 11 from the opened first air return port 112, or enter the first fan chamber 11 from the communicated first communication passage 141, and the air entering the first fan chamber 11 can be discharged from the first air supply port 111. A heat exchanger 5 can be provided in the heat exchange chamber 12. When air flows through the heat exchange chamber 12, it can pass through the heat exchanger 5 and exchange heat with the heat exchanger 5 to realize the cooling or heating of the air.

[0033] The indoor unit of the air conditioner according to the embodiment of the present application can have a fresh air mode and an exhaust air mode. Among them, as Figure 4As shown, when the indoor unit of the air conditioner is in the fresh air mode, the first air return opening 112 is in the closed state. The first control valve 31 can connect the first communication channel 141. The exhaust control valve can connect the first air supply opening 111 of the first fan chamber 11 with the heat exchange chamber 12, and can disconnect the first air supply opening 111 of the first fan chamber 11 from the first chamber 13. At this time, the first fan 21 operates, and the fresh air outdoors can enter the first chamber 13 from the air suction and exhaust opening 133, flow through the first communication channel 141 and the first fan chamber 11 in sequence, and then flow into the heat exchange chamber 12 from the first air supply opening 111 of the first fan chamber 11, and after exchanging heat with the heat exchanger 5 in the heat exchange chamber 12, flow into the room from the air outlet 18 (the flow direction of the air flow is as Figure 4 shown by the arrow direction in

[0034] As Figure 5 shown, when the indoor unit of the air conditioner is in the exhaust mode, the first air return opening 112 is in the open state. The first control valve 31 can disconnect the first communication channel 141. The exhaust control valve can disconnect the first air supply opening 111 of the first fan chamber 11 from the heat exchange chamber 12, and can connect the first air supply opening 111 of the first fan chamber 11 with the first chamber 13. At this time, the first fan 21 operates, and the indoor air can enter the first fan chamber 11 from the first air return opening 112, then flow into the first chamber 13 from the first air supply opening 111 of the first fan chamber 11, and be discharged to the outdoors from the air suction and exhaust opening 133 of the first chamber 13 (the flow direction of the air flow is as Figure 5 shown by the arrow direction in

[0035] In addition, the indoor unit of the air conditioner can also have an internal circulation mode. When the indoor unit of the air conditioner is in the internal circulation mode, the first air return opening 112 is in the open state. The first control valve 31 can disconnect the first communication channel 141. The exhaust control valve can connect the first air supply opening 111 of the first fan chamber 11 with the heat exchange chamber 12, and can disconnect the first air supply opening 111 of the first fan chamber 11 from the first chamber 13. At this time, the first fan 21 operates, and the indoor air can enter the first fan chamber 11 from the first air return opening 112, then flow into the heat exchange chamber 12 from the first air supply opening 111 of the first fan chamber 11, and after exchanging heat with the heat exchanger 5 in the heat exchange chamber 12, flow into the room from the air outlet 18.

[0036] The indoor unit of the air conditioner according to the embodiment of the present application is provided with a first cavity 13, controls the connection and disconnection between the first cavity 13 and the first fan cavity 11, and combines with the original first fan 21 for the internal circulation mode, so that the indoor unit of the air conditioner additionally has a fresh air mode and an exhaust mode. When the fresh air mode is turned on, the first fan 21 only does work on the fresh air coming in from the outside, and the air volume generated by it is the fresh air volume. Since the original first fan 21 originally has enough space to be placed in the housing 1, the air volume is relatively large, so that the fresh air volume in the fresh air mode can be larger than that of the existing ducted air conditioner with fresh air function (for example, the fresh air volume can reach 350 m 3 / h).

[0037] Since the original first fan 21 is directly used as the fresh air fan for introducing outdoor fresh air into the room without the need to additionally add a fan, the noise of the whole indoor unit of the air conditioner will be lower than that of the existing ducted air conditioner with fresh air function (for example, it can be about 3 dB lower).

[0038] In addition, since there is no need to newly add a fresh air module with a fan, the overall size of the unit will be smaller than that of the existing ducted air conditioner.

[0039] Therefore, the indoor unit of the air conditioner according to the embodiment of the present application realizes the functions of introducing fresh air from the outside and exhausting the turbid air in the room. Without the need to additionally add a fan on the basis of the original basic model, it has low noise; the unit structure is small in size, low in cost, has a large available installation space, and is more convenient to install.

[0040] In some exemplary embodiments, as Figures 4 - 7b shown, the exhaust control valve includes a second control valve 32 and a third control valve 33.

[0041] The second control valve 32 is arranged in the heat exchange cavity 12, and the second control valve 32 includes a valve body 321 and a second valve 322 movably installed on the valve body 321. The valve body 321 has a valve cavity 323, a first valve port 324, a second valve port 325 and a third valve port 326 communicating with the valve cavity 323. The first valve port 324 communicates with the first air supply port 111, the second valve port 325 communicates with the heat exchange cavity 12, the third valve port 326 communicates with the first cavity 13 through a second communication channel 142, and the second valve 322 is arranged to open or close the second valve port 325. The third control valve 33 is arranged to control the connection and disconnection of the second communication channel 142.

[0042] In this exhaust air control valve, the valve body 321 of the second control valve 32 has a hollow valve cavity 323. The first valve port 324, the second valve port 325, and the third valve port 326 are all communicated with the valve cavity 323. The first valve port 324 is further communicated with the first air supply port 111 of the first blower cavity 11. The second valve port 325 is further communicated with the heat exchange cavity 12. The third valve port 326 is further communicated with the first cavity 13 through the second communication channel 142. A movable second valve 322 is installed on the valve body 321 of the second control valve 32. The second valve 322 can open the second valve port 325 (as shown in Figure 4 ), or close the second valve port 325 (as shown in Figure 5 ), so as to realize the communication or disconnection between the valve cavity 323 of the second control valve 32 and the heat exchange cavity 12, and further realize the communication or disconnection between the first air supply port 111 of the first blower cavity 11 and the heat exchange cavity 12. The third control valve 33 can control the communication (as shown in Figure 5 ) or disconnection (as shown in Figure 4 ) of the second communication channel 142 between the third valve port 326 and the first cavity 13, so as to realize the communication or disconnection between the valve cavity 323 of the second control valve 32 and the first cavity 13, and further realize the communication or disconnection between the first air supply port 111 of the first blower cavity 11 and the first cavity 13.

[0043] By the cooperation of the second control valve 32 and the third control valve 33, the first air supply port 111 of the first blower cavity 11 can be communicated with any one of the heat exchange cavity 12 and the first cavity 13, and disconnected from the other one of the heat exchange cavity 12 and the first cavity 13.

[0044] In some exemplary embodiments, as shown in Figures 4 - 7b , the valve body 321 of the second control valve 32 is wedge-shaped. The first valve port 324 is arranged on the first side wall 327 of the valve body 321 facing the first blower cavity 11. The second valve port 325 is arranged on the second side wall 328 of the valve body 321 opposite to the first side wall 327. One side of the valve body 321 facing the first cavity 13 has an opening to form the third valve port 326. The second valve 322 is rotatably installed in the valve cavity 323 of the valve body 321 so as to open or close the second valve port 325 by rotation. Of course, the second valve 322 can also open or close the second valve port 325 by translational movement or other forms of movement.

[0045] The shape of the valve body 321 of the second control valve 32 may be wedge-shaped, and a first side wall 327 of the valve body 321 facing the first fan chamber 11 is provided with a first valve port 324 so that the first valve port 324 is communicated with the first air supply port 111 of the first fan chamber 11; a second side wall 328 of the valve body 321 opposite to the first side wall 327 is provided with a second valve port 325, and the second valve port 325 may be communicated with the heat exchange chamber 12; a side of the valve body 321 facing the first chamber 13 has an opening to form a third valve port 326, so that the third valve port 326 is communicated with the first chamber 13 through the second connecting channel 142; the side wall of the valve body 321 on the side opposite to the third valve port 326 may seal that side of the valve body 321 to prevent air leakage.

[0046] The second valve 322 may include a second baffle and a second rotating shaft arranged at one end of the second baffle. The second rotating shaft can be rotatably installed in the valve cavity 323 so that the second valve port 325 can be opened or closed by rotating the second baffle, thereby realizing the connection or disconnection between the first air supply port 111 of the first fan cavity 11 and the heat exchange cavity 12.

[0047] The second control valve 32 of the embodiment of the present application has a valve body 321 of a wedge-shaped structure with three sides open and the other two sides sealed, and the second control valve 32 can be arranged between the first air supply port 111 of the first fan chamber 11 and the heat exchanger 5, so that in the exhaust mode, the indoor air can be directly discharged to the outdoors without passing through the heat exchanger 5 for heat exchange, which is beneficial to reducing the exhaust wind resistance; in the fresh air mode or the internal circulation mode, the outdoor fresh air or the indoor air can flow through the heat exchanger 5 and flow into the indoor room after heat exchange with the heat exchanger 5.

[0048] In some exemplary embodiments, Figures 4 - 5 As shown, the first chamber 13 includes a first sub-chamber 131 close to the first fan chamber 11 and a second sub-chamber 132 close to the heat exchange chamber 12, the air intake and exhaust port 133 is connected to the second sub-chamber 132, the second connecting channel 142 is connected to the second sub-chamber 132, and the first connecting channel 141 is connected to the first sub-chamber 131.

[0049] The third control valve 33 includes a third valve 331 movably mounted to the second sub-chamber 132. Figure 5 As shown, the third valve 331 is configured to be movable to the first position to connect the second communication channel 142 and to isolate the first sub-cavity 131 and the second sub-cavity 132; Figure 4 As shown, the third valve 331 is configured to be able to move to the second position to disconnect the second communication channel 142 and connect the first sub-cavity 131 and the second sub-cavity 132. The third valve 331 is rotatably mounted to the second sub-cavity 132 and can be rotatably switched between the first position and the second position. Of course, the third valve 331 can also connect or disconnect the second communication channel 142 by translation or other means of movement.

[0050] The first control valve 31 includes a first valve 311 movably mounted to the first sub-chamber 131. As shown, the first valve 311 is arranged to be able to move to a third position to disconnect the first communication channel 141; as shown, the first valve 311 is also arranged to be able to move to a fourth position towards the wall of the first sub-chamber 131 away from the second sub-chamber 132 to disconnect the first communication channel 141. Among them, the first valve 311 is rotatably mounted to the first sub-chamber 131 and can be rotationally switched between a first position and a second position. Of course, the third valve 331 can also make the second communication channel 142 communicate or disconnect through translational or other forms of movement. Figure 5 As shown, when the first valve 311 moves to the third position, the first communication channel 141 can be disconnected; as shown, when the first valve 311 moves to the fourth position, the first communication channel 141 can also be disconnected. Figure 4 As shown, the first valve 311 is arranged to be able to move to a third position to disconnect the first communication channel 141; as shown, the first valve 311 is also arranged to be able to move to a fourth position towards the wall of the first sub-chamber 131 away from the second sub-chamber 132 to disconnect the first communication channel 141. Among them, the first valve 311 is rotatably mounted to the first sub-chamber 131 and can be rotationally switched between a first position and a second position. Of course, the third valve 331 can also make the second communication channel 142 communicate or disconnect through translational or other forms of movement.

[0051] In the indoor unit of the air conditioner, the first chamber 13 extending from the blower chamber to the heat exchange chamber 12 can be partitioned into a first sub-chamber 131 close to the first blower chamber 11 and a second sub-chamber 132 close to the heat exchange chamber 12. The first sub-chamber 131 and the second sub-chamber 132 can be communicated through a communication hole 134. The third valve 331 of the third control valve 33 is rotatably mounted in the second sub-chamber 132 and can be rotationally switched between a first position and a second position. The third valve 331 can include a third baffle and a third rotating shaft provided at one end of the third baffle. The third rotating shaft is rotatably mounted in the second sub-chamber 132 so as to open or close the second communication channel 142 by the rotation of the third baffle, thereby realizing the communication or disconnection of the second communication channel 142.

[0052] As Figure 5 shown, when the third valve 331 rotates to the first position, the second communication channel 142 can be opened, so that the second communication channel 142 can be communicated. The valve chamber 323 of the second control valve 32 and the second sub-chamber 132 of the first chamber 13 can be communicated through the second communication channel 142, and the third valve 331 rotated to the first position can close the communication hole 134 connecting the first sub-chamber 131 and the second sub-chamber 132 to partition the first sub-chamber 131 and the second sub-chamber 132; as Figure 4 shown, when the third valve 331 rotates to the second position, the second communication channel 142 can be closed, so that the second communication channel 142 can be disconnected. The valve chamber 323 of the second control valve 32 and the second sub-chamber 132 of the first chamber 13 cannot be communicated through the second communication channel 142, and the third valve 331 rotated to the second position can open the communication hole 134 connecting the first sub-chamber 131 and the second sub-chamber 132 to communicate the first sub-chamber 131 and the second sub-chamber 132.

[0053] The first valve 311 of the first control valve 31 is rotatably installed in the first sub-chamber 131 and can be rotated and switched between a third position and a fourth position. The first valve 311 may include a first baffle and a first rotating shaft provided at one end of the first baffle. The first rotating shaft is rotatably installed in the first sub-chamber 131 so as to open or close the first communication channel 141 by rotating the first baffle, thereby realizing the connection or disconnection of the first communication channel 141.

[0054] As Figure 5 shown, when the first valve 311 rotates to the third position, the first communication channel 141 can be closed, so that the first communication channel 141 can be disconnected. At this time, the first sub-chamber 131 of the first chamber 13 and the first fan chamber 11 cannot be connected through the first communication channel 141; As Figure 4 shown, when the first valve 311 rotates to the fourth position, the first communication channel 141 can be opened, so that the first communication channel 141 can be connected. At this time, the first sub-chamber 131 of the first chamber 13 and the first fan chamber 11 can be connected through the first communication channel 141.

[0055] As Figure 4 shown, when the indoor unit of the air conditioner is in the fresh air mode, the first air return opening 112 is in the closed state. The first valve 311 of the first control valve 31 can rotate to the fourth position. The second valve 322 of the second control valve 32 can close the second valve port 325. The third valve 331 of the third control valve 33 can rotate to the second position. At this time, the first fan 21 works. The fresh air outside can enter the second sub-chamber 132 of the first chamber 13 from the air suction and exhaust opening 133, and sequentially flow through the first sub-chamber 131 of the first chamber 13, the first communication channel 141 and the first fan chamber 11, and then can flow out from the first air supply opening 111 of the first fan chamber 11, and sequentially flow through the valve chamber 323 of the second control valve 32 and the heat exchange chamber 12, and finally flow into the room from the air outlet 18.

[0056] As Figure 5 shown, when the indoor unit of the air conditioner is in the exhaust mode, the first air return opening 112 is in the open state. The first valve 311 of the first control valve 31 can rotate to the third position. The second valve 322 of the second control valve 32 can open the second valve port 325. The third valve 331 of the third control valve 33 can rotate to the first position. At this time, the first fan 21 works. The indoor air can enter the first fan chamber 11 from the first air return opening 112, and then can flow out from the first air supply opening 111 of the first fan chamber 11, and sequentially flow through the valve chamber 323 of the second control valve 32 and the second sub-chamber 132 of the first chamber 13, and finally be discharged to the outside from the air suction and exhaust opening 133 of the first chamber 13.

[0057] When the indoor unit of the air conditioner is in the internal circulation mode, the first air return opening 112 is in the open state. The first valve 311 of the first control valve 31 can be rotated to the third position. The second valve 322 of the second control valve 32 can open the second valve port 325. The third valve 331 of the third control valve 33 can be rotated to the second position. At this time, the first fan 21 works, and the indoor air can enter the first fan chamber 11 from the first air return opening 112, then flow out from the first air supply opening 111 of the first fan chamber 11, and sequentially flow through the valve chamber 323 of the second control valve 32 and the heat exchange chamber 12, and finally flow into the room from the air outlet 18.

[0058] In some exemplary embodiments, such as Figure 4 and Figure 5 shown, the indoor unit of the air conditioner further includes a filtering device 4. The filtering device 4 is disposed on one side of the first sub-chamber 131 close to the second sub-chamber 132, or the filtering device 4 is disposed on one side of the first fan chamber 11 close to the first communication channel 141 (or disposed on one side of the first fan chamber 11 close to the first sub-chamber 131). Wherein, the filtering device 4 may include a high-efficiency filter screen.

[0059] Such as Figure 4 and Figure 5 shown, the filtering device 4 can be disposed on one side of the first sub-chamber 131 close to the second sub-chamber 132 so as not to affect the rotation of the first valve 311 of the first control valve 31; or the filtering device 4 can be disposed on one side of the first fan chamber 11 close to the first communication channel 141, so that the filtering device 4 is closer to the air inlet of the first fan 21. When the indoor unit of the air conditioner is in the fresh air mode, the filtering device 4 can filter the outdoor air passing through it into clean air and then discharge it into the room.

[0060] In some exemplary embodiments, such as Figure 2a and Figure 2b shown, a fourth control valve 34 is provided at the first air return opening 112. The first air return opening 112 includes a plurality of sub-air return openings. The fourth control valve 34 includes a plurality of sub-valves 342. The plurality of sub-valves 342 are movably mounted to the chamber wall of the first fan chamber 11 and correspond to the plurality of sub-air return openings one by one. The plurality of sub-valves 342 are configured to be able to move to the fifth position to open the corresponding sub-air return opening, and the plurality of sub-valves 342 are configured to be able to move to the sixth position to close the corresponding sub-air return opening.

[0061] The first air return opening 112 can be arranged on the first cavity wall 113 of the first blower cavity 11, and the first air return opening 112 can include a plurality of sub-air return openings; correspondingly, the fourth control valve 34 includes a plurality of sub-valves 342, and the plurality of sub-valves 342 can move and switch between a fifth position and a sixth position so as to open or close the plurality of sub-air return openings. Wherein, when the indoor unit of the air conditioner is in the fresh air mode, the plurality of sub-valves 342 close the plurality of sub-air return openings. At this time, when the first blower 21 operates, indoor air cannot enter the first blower cavity 11 through the sub-air return openings, but fresh air can enter the first blower cavity 11 through the first cavity 13; when the indoor unit of the air conditioner is in the exhaust mode or the internal circulation mode, the plurality of sub-valves 342 open the plurality of sub-air return openings. At this time, when the first blower 21 operates, indoor air can enter the first blower cavity 11 through the sub-air return openings.

[0062] In some exemplary embodiments, such as Figure 2a and Figure 2b shown, the sub-valve 342 includes a rotating shaft 344 and a first convex portion 345 and a second convex portion 346 arranged on both sides of the rotating shaft 344, and the rotating shaft 344 is rotatably installed in the corresponding sub-air return opening. As Figure 2a and Figure 2b shown, when the sub-valve 342 is in the fifth position, the first convex portion 345 and the second convex portion 346 face the air inlet side and the air outlet side of the sub-air return opening respectively, and ventilation gaps are provided between both sides of the rotating shaft 344, the first convex portion 345 and the second convex portion 346 and the two inner side wall surfaces of the sub-air return opening; when the sub-valve 342 is in the sixth position, the first convex portion 345 and the second convex portion 346 are respectively in contact with both sides of the sub-air return opening.

[0063] The sub-valve 342 is rotatably installed in the sub-air return opening through the rotating shaft 344. As Figure 2a and Figure 2b shown, when the sub-valve 342 rotates to the fifth position, the first convex portion 345 and the second convex portion 346 face the air inlet side and the air outlet side of the sub-air return opening respectively, so that ventilation gaps are provided between both sides of the rotating shaft 344, the first convex portion 345 and the second convex portion 346 and the two inner side wall surfaces of the sub-air return opening, so as to open the sub-air return opening and enable the sub-air return opening to intake air; when the sub-valve 342 rotates to the sixth position, the first convex portion 345 and the second convex portion 346 are respectively in contact with both sides of the sub-air return opening to close the sub-air return opening and prevent the sub-air return opening from intake air.

[0064] In some exemplary embodiments, such as Figures 1 - 2 、 Figures 3 - 6As shown, the blower cavity further includes a second blower cavity 15, and the second blower cavity 15 is located on the side of the first blower cavity 11 away from the first cavity 13. The indoor unit of the air conditioner further includes a second blower 22, and the second blower 22 is disposed in the second blower cavity 15. A second air supply opening 151 and a second air return opening are provided on the cavity wall of the second blower cavity 15, and the second air supply opening 151 communicates with the heat exchange cavity 12.

[0065] When the indoor unit of the air conditioner is in the internal circulation mode, the second blower 22 can also operate, and indoor air can also enter the second blower cavity 15 from the second air return opening, and can enter the heat exchange cavity 12 from the second air supply opening 151. After the air exchanges heat with the heat exchanger 5 in the heat exchange cavity 12, it can flow back into the room from the air outlet 18.

[0066] When the indoor unit of the air conditioner is in the internal circulation mode, the first blower 21 and the second blower 22 can operate simultaneously to increase the air volume and improve the refrigeration or heating effect.

[0067] In some exemplary embodiments, as Figure 3 shown, the first blower 21 includes a first motor 211 and a first centrifugal blower wheel 212, and the first motor 211 is connected to the first centrifugal blower wheel 212.

[0068] In some exemplary embodiments, as Figures 1 - 2 、 Figures 3 - 6 shown, the second blower 22 includes a second motor 221 and two second centrifugal blower wheels 222. The two second centrifugal blower wheels 222 are respectively disposed on both sides of the second motor 221, and both of the two second centrifugal blower wheels 222 are connected to the second motor 221.

[0069] It should be understood that the first blower 21 may also include two first centrifugal blower wheels 212, or the second blower 22 may also include only one second centrifugal blower wheel 222.

[0070] In some exemplary embodiments, as Figures 1 - 2 、 Figures 3 - 6 shown, the housing 1 includes a first housing 16 and a second housing 17. The first housing 16 and the second housing 17 are of a split structure and are fixedly connected, and the blower cavity and the heat exchange cavity 12 are formed in the first housing 16, and the first cavity 13 is formed in the second housing 17.

[0071] The housing 1 includes a split first housing 16 and second housing 17. The first housing 16 and the second housing 17 can be fixedly connected to form the whole housing 1. Among them, the first housing 16 and the second housing 17 can be detachably connected by means of screws, snap connections, etc.

[0072] The blower cavity and the heat exchange cavity 12 can be formed within the first housing 16, and components such as the first blower 21, the second blower 22, and the heat exchanger 5 are also installed within the first housing 16; the first cavity 13 can be formed within the second housing 17. Since no components such as a fresh air blower are provided within the second housing 17, the size of the second housing 17 is smaller and the weight is lighter compared to the size of the fresh air module in the prior art, making the size of the indoor unit of the air conditioner in the embodiment of the present application smaller and the weight lighter.

[0073] In some exemplary embodiments, such as Figure 6 As shown, a first partition 191 and a second partition 192 are provided within the first housing 16. The first partition 191 can divide the internal space of the first housing 16 into a blower cavity and the heat exchange cavity 12, and the second partition 192 can be disposed within the blower cavity to divide the blower cavity into a first blower cavity 11 and a second blower cavity 15. A first air supply hole 111 and a second air supply port 151 can be provided on the first partition 191, and the second control valve 32 can be provided between the first partition 191 and the heat exchanger 5.

[0074] In some exemplary embodiments, such as Figures 1 - 2 、 Figures 3 - 6 As shown, a first lifting lug 161 is provided on the side of the first housing 16 away from the second housing 17, and a second lifting lug 171 is provided on the side of the second housing 17 away from the first housing 16; or, a first lifting lug 161 is provided on the side of the first housing 16 away from the second housing 17, and a second lifting lug 171 is provided on the side of the first housing 16 close to the second housing 17. Among them, two first lifting lugs 161 and two second lifting lugs 171 can be provided.

[0075] In this housing 1, the fixedly connected first housing 16 and second housing 17 are respectively provided with a first lifting lug 161 and a second lifting lug 171, and the first lifting lug 161 and the second lifting lug 171 are respectively disposed on the sides of the first housing 16 and the second housing 17 away from each other. Among them, the first housing 16 and the second housing 17 can be arranged side by side, for example: the first housing 16 can be disposed on the left side of the second housing 17, the first lifting lug 161 can be disposed on the left side of the first housing 16, and the second lifting lug 171 can be disposed on the right side of the second housing 17.

[0076] Or, both the first lifting lug 161 and the second lifting lug 171 can be provided on the first housing 16, and the second lifting lug 171 and the second lifting lug 171 are respectively disposed on the side of the first housing 16 close to the second housing 17 and the side away from the second housing 17. Among them, the first housing 16 and the second housing 17 can be arranged side by side, the first lifting lug 161 can be disposed on the left side of the first housing 16, and the second lifting lug 171 can be disposed on the right side of the first housing 16.

[0077] The indoor unit of the air conditioner can be a duct machine, which can be hoisted on the ceiling through the first lifting lug 161 and the second lifting lug 171. When both the first lifting lug 161 and the second lifting lug 171 are arranged on the first housing 16, it is convenient to separately disassemble the second housing 17 for operations such as maintenance and replacement of the filter device 4.

[0078] The housing 1 can not only include a split first housing 16 and a second housing 17 to respectively form different cavities such as a first blower cavity 11, a second blower cavity 15, a heat exchange cavity 12, and a first cavity 13 within the first housing 16 and the second housing 17, so that the newly added second housing 17 (the first cavity 13) is a split structure from the original first housing 16; or, the housing 1 can also be an integral structure, and different cavities are formed by arranging a partition assembly within the housing 1.

[0079] For example: in some exemplary embodiments, a partition assembly is provided within the housing 1, and the partition assembly divides the internal space of the housing 1 into a first blower cavity 11, a second blower cavity 15, a heat exchange cavity 12, and a first cavity 13.

[0080] The housing 1 can be an integral structure, and the partition assembly can include a plurality of partitions (such as three partitions) to divide the internal space of the housing 1 into a first blower cavity 11, a second blower cavity 15, a heat exchange cavity 12, and a first cavity 13, so that the newly added first cavity 13 and the original blower cavity and heat exchange cavity 12 are formed within an integral housing 1.

[0081] In some exemplary embodiments, the indoor unit of the air conditioner includes a duct machine or a ceiling-mounted and wall-mounted machine.

[0082] The embodiment of the present application also provides an air conditioner, including the indoor unit of the air conditioner described in any of the above embodiments.

[0083] In summary, for the indoor unit of the air conditioner in the embodiment of the present application, one of the original three centrifugal fans that can operate independently (the first centrifugal fan 212) and its driving motor (the first motor 211) are used as a fresh air blower (the first blower 21), and the cavity where the independently operating centrifugal fan (the first centrifugal fan 212) and its driving motor (the first motor 211) are located is separated to form a first blower cavity 11.

[0084] A second control valve 32 is provided between the heat exchanger 5 (which can be used as an evaporator or a condenser) and the first air supply opening 111 of the first blower cavity 11. A first control valve 31 is provided in the first sub-cavity 131 of the first cavity 13, a third control valve 33 is provided in the second sub-cavity 132 of the first cavity 13, and a fourth control valve 34 is provided at the first air return opening 112 of the first blower cavity 11.

[0085] The switching between the internal circulation mode (conventional refrigeration / heating mode), fresh air mode, exhaust air mode, etc. is achieved by controlling each control valve. The valve body 321 of the second control valve 32 is closed on the side close to the second fan 22, and the air flow cannot pass through. The opposite side (the side facing the first chamber 13) is in an open state. The first control valve 31 is located between the port where the first communication channel 141 communicates with the first sub-chamber 131 and the filtering device 4. When the first control valve 31 is opened (the first valve 311 of the first control valve 31 moves to the fourth position), outdoor fresh air can enter the first fan chamber 11 through the first communication channel 141. When the first control valve 31 is closed (the first valve 311 of the first control valve 31 moves to the third position), the fresh air cannot enter the first fan chamber 11 through the first communication channel 141. The third control valve 33 is located between the port where the second communication channel 142 communicates with the second sub-chamber 132 and the filtering device 4. When the third control valve 33 is opened (the third valve 331 of the third control valve 33 moves to the first position), indoor air can enter the second sub-chamber 132 through the second communication channel 142. When the third control valve 33 is closed (the third valve 331 of the third control valve 33 moves to the second position), the air flow cannot enter the second sub-chamber 132 through the second communication channel 142.

[0086] As Figure 4 shown, when the fresh air mode is turned on, the fourth control valve 34 is in a closed state (the multiple sub-valves 342 of the fourth control valve 34 move to the sixth position). Under the action of the first fan 21, outdoor fresh air can enter the second sub-chamber 132 of the first chamber 13 through the fresh air pipe (connected to the air intake and exhaust port 133) from the air intake and exhaust port 133. Since the third valve 331 of the third control valve 33 connects the first sub-chamber 131 and the second sub-chamber 132 of the first chamber 13 at this time and disconnects the second communication channel 142, the fresh air in the second sub-chamber 132 can enter the first sub-chamber 131 of the first chamber 13 after being filtered by the filtering device 4. Since the first control valve 31 is in an open state at this time, the fresh air can directly enter the first fan chamber 11 through the first communication channel 141 and enter the first centrifugal impeller 212 of the first fan 21. The air flow blows into the valve chamber 323 of the second control valve 32 after coming out of the first centrifugal impeller 212. Since the second control valve 32 is in an open state at this time (the second valve 322 of the second control valve 32 opens the second valve port 325), the fresh air comes out of the valve chamber 323 of the second control valve 32 and then enters the heat exchange chamber 12, and enters the room after heat exchange by the heat exchanger 5.

[0087] As Figure 5As shown, when the exhaust mode is turned on, the fourth control valve 34 is in the open state (multiple sub-valves 342 of the fourth control valve 34 move to the fifth position), and the first control valve 31 is in the closed state (the first valve 311 rotates to the third position to disconnect the first communication channel 141). Under the action of the first fan 21, the indoor air can enter the first fan chamber 11 from the first air return opening 112 and directly enter the first centrifugal impeller 212 of the first fan 21. After the air flow comes out of the first centrifugal impeller 212, it blows into the valve chamber 323 of the second control valve 32. At this time, the second control valve 32 is in the closed state (the second valve 322 of the second control valve 32 closes the second valve port 325). The second control valve 32 changes the direction of the air flow so that the air flow flows into the second communication channel 142. At this time, the third control valve 33 is in the open state (connects the second communication channel 142 and disconnects the first sub-chamber 131 and the second sub-chamber 132 of the first chamber 13). The air flow passes through the second communication channel 142, flows to the second sub-chamber 132 of the first chamber 13, and finally the air flow is led to the outside through the air suction and exhaust opening 133 and the fresh air pipe.

[0088] When the internal circulation mode is turned on, the fourth control valve 34 is in the open state (multiple sub-valves 342 of the fourth control valve 34 move to the fifth position), and the first control valve 31 is in the closed state (the first valve 311 rotates to the third position to disconnect the first communication channel 141). Under the action of the first fan 21, the indoor air can enter the first fan chamber 11 from the first air return opening 112 and directly enter the first centrifugal impeller 212 of the first fan 21. After the air flow comes out of the first centrifugal impeller 212, it blows into the valve chamber 323 of the second control valve 32. At this time, the second control valve 32 is in the open state (the second valve 322 of the second control valve 32 opens the second valve port 325). After the air flow comes out of the valve chamber 323 of the second control valve 32, it enters the heat exchange chamber 12, and after heat exchange by the heat exchanger 5, it enters the room. When the internal circulation mode is turned on, the second fan 22 can also be started. Under the action of the second fan 22, the indoor air can enter the second fan chamber 15 from the second air return opening and directly enter the second centrifugal impeller 222 of the second fan 22. After the air flow comes out of the second centrifugal impeller 222, it enters the heat exchange chamber 12, and after heat exchange by the heat exchanger 5, it enters the room.
