So set up, can carry out the air-out according to heat transfer mode reasonable selection indoor air outlet 13 to reach better air supply effect, promote indoor heat transfer effect. For example, in the heating mode, since the hot air flow flows upward after being sent out from the indoor air outlet 13, the air can be sent out through the indoor air outlet 13 below, so that the hot air flow is sent out downward as much as possible, and the hot air flow can be better distributed indoors. In the cooling mode, the cold airflow is sent out from the indoor air outlet 13 and then flows downwards, so that the air can be supplied through the indoor air outlet 13 above, and the cold airflow is sent out upwards as much as possible, so that the cold airflow can be better distributed indoors. And two indoor air outlets 13 are arranged on the front surface 14 of the inner shell, so that the air supply range in the left and right directions is larger while the air supply range in the up and down directions is enlarged.

Or the two indoor air outlets 13 are respectively arranged on the two inner shell side surfaces 15.

Referring to fig. 3 and 4, in an embodiment, two centrifugal wind wheels 20 are arranged at intervals in the vertical direction. The air inlet side of the centrifugal wind wheel 20 positioned above is communicated with the indoor air outlet 13 close to the upper part, and the air inlet side of the centrifugal wind wheel 20 positioned below is communicated with the indoor air outlet 13 close to the lower part. That is, the two centrifugal wind wheels 20 are arranged in the up-down direction, so that the sizes of the internal machine casing 10 in the left-right direction and the front-back direction can be reduced, and the indoor occupied area of the internal machine casing 10 can be reduced. But also can make the indoor air outlet 13 at the upper end at a higher position, so that the cold air flow can be sent to the indoor higher position in the cooling mode. Of course, in other embodiments, the two wind wheels may be arranged at intervals in the left-right direction.

In one embodiment, one indoor air inlet 12 is provided, and the air inlet sides of the two centrifugal wind wheels 20 are communicated with the indoor air inlet 12. That is, the air inlet sides of the two centrifugal wind wheels 20 share one indoor air inlet 12, and thus, the number of the indoor air inlets 12 on the inner machine shell 10 is reduced, which is beneficial to simplifying the structure of the inner machine shell 10 and reducing the production cost. And when locating this indoor air intake 12 inboard with indoor side heat exchanger 30, can also share same indoor side heat exchanger 30, reduce the quantity of indoor side heat exchanger 30, when simplifying the structure, can also reduce the assembly process, promote production efficiency. Of course, in other embodiments, an independent indoor air inlet 12 may be provided on the inner machine casing 10 corresponding to each centrifugal wind wheel 20.

Further, in an embodiment, the indoor air inlet 12 is located between the two centrifugal wind wheels 20, and the two centrifugal wind wheels 20 are spaced from the indoor air inlet 12 in the up-down direction. That is, the indoor air inlet 12 and the two indoor air outlets 13 are both disposed on the front surface 14 of the inner casing, and the two centrifugal wind wheels 20 are both staggered with the indoor air inlet 12 in the front-rear direction. That is, the orthographic projections of the two centrifugal wind wheels 20 on the front surface 14 of the inner shell are respectively arranged on two sides of the indoor air inlet 12, so that when the indoor side heat exchanger 30 is arranged on the inner side of the indoor air inlet 12, the indoor side heat exchanger 30 and the two centrifugal wind wheels 20 are spaced in the up-down direction, the situation that the indoor side heat exchanger 30 and the centrifugal wind wheels 20 share the space of the front-back direction of the inner machine shell 10 can be avoided, and the size of the inner machine shell 10 in the front-back direction can be reduced. Of course, in other embodiments, the indoor air inlet 12 may be disposed on the left side or the right side of the two centrifugal wind wheels 20. Or the indoor air inlet 12 is provided to the inner case side 15.

Corresponding to two centrifugal wind wheels 20 positioned between the two indoor air outlets 13. So can make the interval between two indoor air outlets 13 bigger to can further increase air supply range. In the embodiment where the indoor air inlet 12 is located between the two indoor air outlets 13, this also reduces the possibility that the outlet airflow sent out from the indoor air outlet 13 is directly sucked into the indoor air inlet 12. Of course, in other embodiments, the two indoor air outlets 13 may also be disposed between the two wind wheels in the up-down direction.

In one embodiment, an air outlet duct 17 is formed between the centrifugal wind wheel 20 and the indoor air outlet 13, and in the air outlet direction, the air outlet duct 17 gradually inclines towards the direction far away from the other indoor air outlet 13. Therefore, the distance between the two indoor air outlets 13 is farther, and the air supply range can be further enlarged. For example, when two indoor air outlets 13 are arranged at intervals in the vertical direction, namely the upper air outlet duct 17 extends obliquely upward, and the lower air outlet duct 17 extends obliquely downward, so that the air flow sent out by the upper indoor air outlet 13 can be sent to a higher position in a room, and the air flow sent out by the lower indoor air outlet 13 can be better sent to the bottom surface, and the air supply effect in the cooling mode and the heating mode can be improved. In the embodiment where the indoor air inlet 12 is located between the two indoor air outlets 13, such that the outlet airflow is sent out obliquely upward and obliquely downward, the possibility that the outlet airflow sent out from the indoor air outlet 13 is directly sucked by the indoor air inlet 12 can be further reduced. Of course, in other embodiments, the extending direction of the air outlet duct 17 may also be perpendicular to the front surface 14 of the inner casing.

In one embodiment, the indoor air duct 11 includes two independent sub-air ducts, each of the sub-air ducts has a centrifugal wind wheel 20, and the inner machine casing 10 has two indoor air inlets 12. One of the indoor air outlets 13 and one of the indoor air inlets 12 are communicated with one of the sub-air ducts, and the other indoor air outlet 13 and the other indoor air inlet 12 are communicated with the other sub-air duct. Therefore, the two centrifugal wind wheels 20 can be ensured to be mutually independent, so that the air inlet flows of the two centrifugal wind wheels 20 are ensured to be mutually independent in the internal machine shell 10, and the situation that the air suction flow of the other centrifugal wind wheel 20 is reduced due to overlarge negative pressure generated by one centrifugal wind wheel 20 is avoided. Thereby can be convenient for independently adjust the air-out speed of two centrifugal wind wheels 20 to can realize the air supply of different speed, different amount of wind to two different regions simultaneously, can realize multiple air-out mode, satisfy different air supply demands. The indoor air outlets 13 of the two sub-air ducts may be all disposed on the front surface 14 of the inner shell, or may be all disposed on the side surface 15 of the same inner shell, or the indoor air outlets 13 of the two sub-air ducts are separately disposed on the side surfaces 15 of the two inner shells, or the indoor air outlet 13 of one of the two sub-air ducts is disposed on the front surface 14 of the inner shell, and the indoor air outlet 13 of the other sub-air duct is disposed on the side surface 15 of the inner shell.

In order to allow the outer casing 40 to extend outdoors, a mounting opening is generally provided in the wall body so that the outer casing 40 can extend outdoors from the mounting opening, and in this case, the portion of the space (mounting opening) between the inner surface of the wall body and the outer surface of the wall body can be regarded as outdoors, that is, the space inside the inner surface of the wall body can be regarded as indoors, and the space outside the inner surface of the wall body can be regarded as outdoors.

Referring to fig. 2, 7 and 8, generally, the outer casing 40 is provided with an outdoor air outlet 42 and an outdoor air inlet 41, and the outdoor air outlet 42 and the outdoor air inlet 41 are both communicated with the outdoor air duct and the outdoor space. The outdoor air outlet 42 and the outdoor air inlet 41 may be directly connected to the outside of the room, or may be connected to the outside of the room through a connection pipe. For example, when the unitary air conditioner is placed indoors (i.e., the outer cabinet 40 is placed indoors), the outdoor air outlet 42 may communicate with the outside of the room through one connection pipe, and the outdoor air inlet 41 may communicate with the outside of the room through another connection pipe. It is also possible to partially extend the outer cabinet 40 to the outside of the room such that the outdoor outlet 42 and the outdoor inlet 41 are exposed to the outside of the room.

When the unitary air conditioner is installed, the inner machine casing 10 and the compressor 50 may be placed indoors, and the outer machine casing 40 may be extended outdoors. By arranging the compressor 50 in the inner unit casing 10, the overall weight of the outer unit casing 40 is reduced, and thus, when the outer unit casing 40 is installed on a floor of a building above the second floor, the pressure of the outer unit casing 40 on the support frame can be reduced. For example, when the integrated air conditioner is used in a portable house (container house) having two or more layers, the pressure on the support frame can be reduced by installing the outer casing 40 outdoors, and when the outer casing 40 is connected to the inner casing 10, the outer casing 40 can be supported without providing the support frame, which can facilitate use in the portable house or the container house. Of course, in other embodiments, the compressor 50 may be disposed in the outer casing 40.

In an embodiment, the compressor 50 is located below the centrifugal wind wheel 20, so that the center of gravity of the inner machine casing 10 is low, and the stability of the inner machine casing 10 during placement can be improved. Of course, in other embodiments, the centrifugal rotor 20 and the compressor 50 may be distributed in the left-right direction (front-rear direction).

In one embodiment, the unitary air conditioner further includes a shielding case 70, and the shielding case 70 is disposed in the inner machine casing 10 and covers the compressor 50. The space where the compressor 50 is located can be separated from other inner chambers of the inner machine casing 10 by the shield 70, and heat and noise generated by the compressor 50 can be reduced from being radiated into the room. In order to enhance the heat insulating effect of the insulating cover 70, the insulating cover 70 is made of a heat insulating material. In order to enhance the effect of the shield 70 in blocking the compression noise, the shield 70 is made of a sound insulating material.

Generally, the unitary air conditioner further includes an outdoor fan 80 and an outdoor side heat exchanger 60, and both the outdoor fan 80 and the outdoor side heat exchanger 60 are disposed in the outdoor air duct. The outdoor fan 80 may be a centrifugal fan (see fig. 11), an axial flow fan (see fig. 7), a cross flow fan, or the like, and the compressor 50 is connected to the indoor heat exchanger 30 and the outdoor heat exchanger 60 through a refrigerant pipe.

In one embodiment, the outdoor heat exchanger 60 is disposed on the air inlet side of the outdoor fan 80. That is, the outdoor heat exchanger 60 is disposed between the air inlet side of the outdoor fan 80 and the outdoor air inlet 41, and when the outdoor air enters from the outdoor air inlet 41, the outdoor air firstly passes through the outdoor heat exchanger 60 to exchange heat, and then passes through the outdoor fan 80 and the outdoor air outlet 42 to be discharged to the outdoor space. Therefore, dust accumulated on the inner side of the outdoor heat exchanger 60 can be reduced, and the possibility of water entering the outer machine shell 40 in rainy days can be reduced, so that the safety is improved. When the outdoor heat exchanger is arranged in this way, a plurality of outdoor air inlets 41 can be arranged on the outer machine shell 40, and the inner side of each outdoor air inlet 41 is provided with the outdoor heat exchanger 60, so that the heat exchange effect can be increased.

Referring to fig. 9, in an embodiment, the outdoor heat exchanger 60 is disposed at an air outlet side of the outdoor fan 80. That is, the outdoor heat exchanger 60 is disposed between the air inlet side of the outdoor fan 80 and the outdoor air outlet 42, and when the outdoor air enters from the outdoor air inlet 41, the outdoor air passes through the outdoor fan 80, and then sequentially passes through the outdoor heat exchanger 60 and the outdoor air outlet 42 and is discharged to the outdoor space. So when the refrigeration mode for outdoor air current through outdoor fan 80 is the air current that does not exchange heat, is favorable to dispelling the heat to outdoor fan 80.

Referring to fig. 1 and 2, the outer casing 40 has a casing back 43, a casing top 44 and two casing side surfaces 45, wherein the casing back 43 is a surface of the outer casing 40 facing away from the inner casing 10. For example, referring to fig. 8 or 9, in an embodiment, the outdoor air outlet 42 is disposed on the back 43 of the housing, the outdoor air inlet 41 is disposed on the side 45 of the housing, and the outdoor air outlet 42 is disposed on the back 43 of the housing, so that the outdoor air outlet 42 is far away from the wall, the possibility of the air outlet being blocked can be reduced, and the air outlet effect can be ensured. The outdoor air inlet 41 may be provided on one of the housing side surfaces 45, or the outdoor air inlets 41 may be provided on each of the two housing side surfaces 45.

In addition, referring to fig. 7, in an embodiment, the outdoor air outlet 42 is disposed on one of the housing side surfaces 45, and the outdoor air inlet 41 is disposed on the housing back surface 43, so that the possibility of shielding the air outlet can be reduced, and the air outlet effect can be ensured. In this embodiment, another outdoor air inlet 41 may be disposed on another side surface 45 of the housing.

In addition, referring to fig. 10 or fig. 11, in an embodiment, the outdoor air outlet 42 is disposed on the top surface 44 of the housing, and the outdoor air inlet 41 is disposed on the side surface 45 or the back surface 43 of the housing, so that the outdoor air inlet 41 may be disposed on both the back surface 43 and the two side surfaces 45 of the housing, and an outdoor heat exchanger 60 may be disposed inside each outdoor air inlet 41, so as to increase a heat exchange area.
