Generally, the inner machine case 10 is provided indoors, that is, both the indoor air inlet 12 and the indoor air outlet 13 communicate with the indoor space, so that heat exchange of indoor air can be performed. Of course, the installation position of the inner machine casing 10 is not limited herein, and for example, the inner machine casing 10 may be installed outdoors, so that both the indoor air inlet 12 and the indoor air outlet 13 communicate with the indoor space.

According to the technical scheme, the centrifugal wind wheel 21 and the axial flow wind wheel 22 are arranged in the inner machine shell 10, so that when the integral air conditioner is used, if large-air-volume air supply is needed, main air supply can be performed through the axial flow wind wheel 22. When the air needs to be supplied to a remote place, the main air supply can be performed through the centrifugal wind wheel 21, so that the outlet air flow can be sent to a remote place. And the centrifugal wind wheel 21 and the axial flow wind wheel 22 can be started simultaneously to supply air, so that the requirement of long-distance air supply can be met when the requirement of large-air-volume air supply is met.

That is, each indoor air outlet 13 can independently supply air, so that the air outlet position on the inner machine shell 10 is increased, and the air supply range can be enlarged. For example, when the two indoor outlets 13 are provided at an interval in the vertical direction, the air blowing range in the vertical direction can be increased, and when the two indoor outlets 13 are provided at an interval in the horizontal direction, the air blowing range in the horizontal direction can be increased. Of course, in other embodiments, only one indoor air outlet 13 may be provided, and both the air outlet side of the centrifugal wind wheel 21 and the air outlet side of the axial wind wheel 22 are communicated with the indoor air outlet 13.

The inner shell body has an inner shell front 14, an inner shell back 16, and two inner shell sides 15, the inner shell front 14 being opposite the inner shell back 16, the two inner shell sides 15 being opposite, each inner shell side 15 being located between the inner shell front 14 and the inner shell back 16. Typically, the unitary air conditioner is used with the back 16 of the inner housing facing adjacent a wall surface, such as when the unitary air conditioner is placed against a wall.

The two indoor air outlets 13 may be disposed on the front surface 14 of the inner casing, or one of the indoor air outlets 13 may be disposed on the front surface 14 of the inner casing, and the other indoor air outlet 13 may be disposed on the side surface 15 of the inner casing. Of course, in other embodiments, two indoor air outlets 13 may be provided on the inner casing side surface 15.

The indoor air inlet 12 can be disposed in various positions, for example, in one embodiment, at least one indoor air inlet 12 is disposed on the front surface 14 of the inner casing 10. That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the front surface 14 of the inner casing, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided on the front surface 14 of the inner casing. The indoor air inlet 12 is also arranged at the front side of the integral air conditioner, so that the possibility that the indoor air inlet 12 is shielded by indoor objects can be reduced, and the air inlet effect is ensured. Wherein, two indoor air inlets 12 can be arranged on the front surface 14 of the inner shell; or one of the indoor air outlets 13 is arranged on the front surface 14 of the inner shell, and the other indoor air outlet 13 is arranged on the side surface 15 of the inner shell; or one of the indoor air outlets 13 is arranged on the front surface 14 of the inner shell, and the other indoor air outlet 13 is arranged on the back surface 16 of the inner shell.

In another embodiment, at least one indoor air intake 12 is provided in the inner casing side 15 of the inner casing 10. That is, when one indoor air inlet 12 is provided, the air inlet is provided at the side surface 15 of the inner case, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided at the side surface 15 of the inner case. When indoor air outlet 13 locates inner shell openly 14, so can make the interval between indoor air outlet 13 and the indoor air intake 12 far away, and make indoor air outlet 13 and indoor air intake 12 respectively towards different directions, can reduce the air-out air current that blows off from indoor air outlet 13 and directly inhaled the possibility of indoor air intake 12, can also promote the circulation effect of room air, realize the abundant circulation heat transfer of room air. The two indoor air inlets 12 may be disposed on the inner casing side surface 15, at this time, two indoor air inlets 12 may be disposed on two side surfaces of the inner casing 10, the two indoor air ducts 11 are communicated with the two indoor air inlets 12 in a one-to-one correspondence, or two indoor air inlets 12 may be disposed on each inner casing side surface 15, one indoor air inlet 12 is disposed on each of the two inner casing side surfaces 15 and is communicated with one of the indoor air ducts 11, and the other indoor air inlets 12 of the two inner casing side surfaces 15 are communicated with the other indoor air duct 11. Or one of the indoor air outlets 13 is arranged on the side surface 15 of the inner shell, and the other indoor air outlet 13 is arranged on the back surface 16 of the inner shell.

In another embodiment, all of the indoor air inlets 12 may be disposed on the back surface 16 of the inner casing. That is, when one indoor air inlet 12 is provided, the indoor air inlet 12 is provided on the back surface 16 of the inner casing, and when two or more indoor air inlets 12 are provided, all the indoor air inlets 12 are provided on the back surface 16 of the inner casing. When indoor air outlet 13 locates inner shell openly 14, so can make the interval between indoor air outlet 13 and the indoor air intake 12 far away, and make indoor air outlet 13 and indoor air intake 12 respectively towards different directions, can reduce the air-out air current that blows off from indoor air outlet 13 and directly inhaled the possibility of indoor air intake 12, can also promote the circulation effect of room air, realize the abundant circulation heat transfer of room air.

In one embodiment, the two indoor outlets 13 are spaced in the vertical direction. 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. Of course, in other embodiments, the two indoor air outlets 13 may be distributed at intervals in the left-right direction. Or the two indoor air outlets 13 are respectively arranged on the two inner shell side surfaces 15.

In one embodiment, the axial flow wind wheel 22 and the centrifugal wind wheel 21 are arranged at intervals in the vertical direction. That is, the axial flow wind wheel 22 and the centrifugal wind are arranged in the up-down direction, so that the size of the inner machine casing 10 in the left-right direction and the front-back direction can be reduced, and the indoor occupied area of the inner machine casing 10 can be reduced. But also the upper indoor air outlet 13 is at a higher position, so that the cold air flow can be sent to a higher position in the room in the cooling mode. Of course, in other embodiments, the axial flow wind wheel 22 and the centrifugal wind wheel 21 may be arranged at an interval in the left-right direction.

There are various ways of disposing axial wind wheel 22 and centrifugal wind wheel 21 in inner machine shell 10, for example, in an embodiment, axial wind wheel 22 is disposed below centrifugal wind wheel 21 at intervals. That is, the centrifugal wind wheel 21 is disposed above the axial flow wind wheel 22, so that in the cooling mode, main air supply can be performed through the centrifugal wind wheel 21 to ensure that the air supply distance of the cold air flow is long. In the heating mode, the axial flow wind wheel 22 can be used for mainly supplying air to ensure that the air volume of hot air flow is larger and indoor rapid heating is realized.

In another embodiment, axial flow wind wheel 22 is spaced above centrifugal wind wheel 21. Centrifugal wind wheel 21 locates the below of axial compressor wind wheel 22 promptly, so when the refrigeration mode, can carry out main air supply through axial compressor wind wheel 22 to guarantee that the amount of wind of cold air current is great, realize indoor rapid cooling. In the heating mode, the centrifugal wind wheel 21 can be used for mainly supplying air so as to ensure that the air supply distance of hot air flow is longer.

In one embodiment, the indoor air outlet 13 communicated with the air outlet side of the centrifugal wind wheel 21 is located on one side of the centrifugal wind wheel 21 far away from the axial wind wheel 22. That is, when the centrifugal wind wheel 21 is located above the axial wind wheel 22, the indoor air outlet 13 corresponding to the centrifugal wind wheel 21 is located above the centrifugal wind wheel 21, and when the centrifugal wind wheel 21 is located below the axial wind wheel 22, the indoor air outlet 13 corresponding to the centrifugal wind wheel 21 is located below the centrifugal wind wheel 21. Therefore, the distance between the two indoor air outlets 13 is larger, and the air supply range can be enlarged. 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 21 and the indoor air outlet 13, and in the air outlet direction, the air outlet duct 17 gradually inclines towards the direction away from the axial wind wheel 22. Therefore, the distance between the two indoor air outlets 13 is farther, and the air supply range can be further enlarged. For example, when the centrifugal wind wheel 21 is disposed above the axial flow wind wheel 22, that is, the air outlet duct 17 extends obliquely upward, so that the airflow sent out from the indoor air outlet 13 above can be sent to a higher position indoors, which is beneficial to improving the air supply effect in the cooling mode. When the centrifugal wind wheel 21 is arranged below the axial flow wind wheel 22, namely the air outlet duct 17 extends obliquely downwards, the airflow sent out from the indoor air outlet 13 below can be better sent to the bottom surface, and the air supply effect in the heating mode is favorably 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.

The centrifugal rotor 21 may be mounted in various ways, for example, in one embodiment, the axis of the centrifugal rotor 21 extends in the front-rear direction. That is, the air inlet side of the centrifugal wind wheel 21 is arranged towards the front side or the rear side of the inner machine casing 10, so that the space in the left-right direction and the up-down direction in the inner machine casing 10 can be fully utilized, the radial size of the centrifugal wind wheel 21 is larger, and the air supply quantity of the centrifugal wind wheel 21 is increased. Meanwhile, the centrifugal wind wheel 21 has a small axial size, so that the size of the inner machine shell 10 in the front-back direction can be reduced. In the embodiment where the air inlet side of the centrifugal wind wheel 21 is disposed toward the indoor air inlet 12, that is, the indoor air inlet 12 may be disposed on the front side 14 of the inner casing or on the back side 16 of the inner casing, in the embodiment, the indoor air outlet 13 is disposed on the front side 14 of the inner casing. Of course, in other embodiments, the indoor air inlet 12 may be disposed on the inner casing side 15 when the axis of the centrifugal wind wheel 21 extends in the front-rear direction.

Referring to fig. 4 to 6, in another embodiment, the axis of the centrifugal rotor 21 extends in the left-right direction. That is, the air inlet side of the centrifugal wind wheel 21 is arranged towards the left side or the right side of the inner machine shell 10, it should be understood that the air inlet side of the centrifugal wind wheel 21 is arranged at one axial side, and the air outlet side of the centrifugal wind wheel 21 is arranged at the peripheral surface, so that the air outlet side of the centrifugal wind wheel 21 faces the outdoor air outlet 42 at the front surface 14 of the inner shell, the air flow sent out from the air outlet side of the centrifugal wind wheel 21 can be directly sent out from the outdoor air outlet 42, the condition that the air flow is sent out from the air outlet side of the centrifugal wind wheel 21 to turn to is reduced, the condition that the air flow is excessively lost due to the change of the air flow direction between the air outlet side of the centrifugal wind wheel 21 and the. In the embodiment where the air inlet side of the centrifugal wind wheel 21 is disposed toward the indoor air inlet 12, the indoor air inlet 12 is disposed on the inner casing side 15. Of course, in other embodiments, when the axis of the centrifugal wind wheel 21 extends in the left-right direction, the indoor air inlet 12 may also be disposed on the front side 14 or the back side 16 of the inner casing.

In one embodiment, one indoor air inlet 12 is provided, and the air inlet sides of the centrifugal wind wheel 21 and the axial wind wheel 22 are communicated with the indoor air inlet 12. That is, the air inlet sides of the axial flow wind wheel 22 and the centrifugal wind wheel 21 share one indoor air inlet 12, and thus, the number of the indoor air inlets 12 on the internal machine shell 10 is reduced, which is beneficial to simplifying the structure of the internal machine shell 10 and reducing the production cost. Of course, in other embodiments, an indoor air inlet 12 may be provided on the inner machine casing 10 corresponding to each of the axial flow wind wheel 22 and the centrifugal wind wheel 21.

Further, in an embodiment, the unitary air conditioner further includes an indoor heat exchanger 30, and the indoor heat exchanger 30 is disposed at the indoor air inlet 12. That is, the indoor side heat exchanger 30 is disposed at the inner side of the indoor air inlet 12, after the indoor air enters the indoor air duct 11 from the indoor air inlet 12, the heat exchange is performed through the indoor side heat exchanger 30, and the air after the heat exchange is sucked by the axial flow wind wheel 22 and the centrifugal wind wheel 21 respectively and is sent out by the axial flow wind wheel 22 and the centrifugal wind wheel 21 respectively. Therefore, the axial flow wind wheel 22 and the centrifugal wind wheel 21 share one indoor side heat exchanger 30, the number of the indoor side heat exchangers 30 can be reduced, the assembling procedures of the indoor side heat exchangers 30 are also reduced, and the production cost is reduced. Of course, in other embodiments, the indoor heat exchanger 30 may be disposed at the indoor air outlet 13. Or the air inlet sides of the axial flow wind wheel 22 and the centrifugal wind wheel 21 are respectively provided with an indoor side heat exchanger 30.

Referring to fig. 3 or fig. 5, the centrifugal wind wheel 21 and the indoor air inlet 12 have various matching positions, for example, in an embodiment, the air inlet side of the centrifugal wind wheel 21 is disposed toward the indoor air inlet 12. That is, the indoor air inlet 12 is disposed at the position of the inner machine casing 10 facing the air inlet side of the centrifugal wind wheel 21, so that the distance between the air inlet side of the centrifugal wind wheel 21 and the indoor air inlet 12 is small, which is beneficial to shortening the air inlet path and the air duct path between the indoor air inlet 12 and the indoor air outlet 13. When the indoor heat exchanger 30 is disposed at the indoor air inlet 12, the air inlet side of the centrifugal wind wheel 21 faces the inner side surface of the indoor heat exchanger 30. Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the centrifugal wind wheel 21 may be arranged at an interval in the vertical direction.

In another embodiment, the indoor air inlet 12 is disposed on the front surface 14 of the inner casing, and the indoor air inlet 12 and the centrifugal wind wheel 21 are staggered in the front-rear direction. That is, the centrifugal wind wheel 21 is arranged at an interval between the orthographic projection of the front surface 14 of the inner casing and 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 centrifugal wind wheel 21 are staggered in the front-rear direction, the situation that the indoor side heat exchanger 30 and the centrifugal wind wheel 21 share the space of the front-rear direction of the inner casing 10 can be avoided, and the size of the inner casing 10 in the front-rear direction can be reduced.

In another embodiment, the indoor air inlet 12 is located between the centrifugal wind wheel 21 and the axial wind wheel 22, and the centrifugal wind wheel 21 and the axial wind wheel 22 are both spaced from the indoor air inlet 12 in the up-down direction. In this embodiment, 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 centrifugal wind wheel 21 and the axial wind wheel 22 are both staggered from the indoor air inlet 12 in the front-rear direction. Namely, the orthographic projection of the centrifugal wind wheel 21 on the front face 14 of the inner shell is spaced from the indoor air inlet 12, and the orthographic projection of the axial wind wheel 22 on the front face 14 of the inner shell is also spaced from the indoor air inlet 12. So when indoor air intake 12's inboard is equipped with indoor side heat exchanger 30, also make centrifugal wind wheel 21 and axial compressor wind wheel 22 all with indoor side heat exchanger 30 interval in upper and lower direction to can avoid indoor side heat exchanger 30 and centrifugal wind wheel 21, and indoor side heat exchanger 30 and the indoor side heat exchanger 22 sharing the condition in the space of indoor unit casing 10 fore-and-aft direction, can reduce the size of indoor unit casing 10 in the fore-and-aft direction. Of course, in other embodiments, the indoor air inlet 12 may be disposed on the left side or the right side of the centrifugal wind wheel 21. Or the indoor air inlet 12 is provided to the inner case side 15. In addition, in the vertical direction, only the centrifugal wind wheel 21 or the axial wind wheel 22 may be spaced from the indoor air intake 12. In addition, in the vertical direction, the centrifugal wind wheel 21 and the axial wind wheel 22 may also partially overlap or completely overlap the indoor air inlet 12.

Referring to fig. 7, in an embodiment, the indoor air duct 11 includes a first air duct 111 and a second air duct 112 that are independent from each other, one of the indoor air outlets 13 is communicated with the first air duct 111, the other indoor air outlet 13 is communicated with the second air duct 112, the indoor air inlet 12 includes a first air inlet 121 communicated with the first air duct 111 and a second air inlet 122 communicated with the second air duct 112, the axial flow wind wheel 22 is disposed in the first air duct 111, and the centrifugal wind wheel 21 is disposed in the second air duct 112. Therefore, the axial flow wind wheel 22 and the centrifugal wind wheel 21 can be ensured to be mutually independent, so that the air inlet flows of the axial flow wind wheel 22 and the centrifugal wind wheel 21 are ensured to be mutually independent in the inner machine shell 10, and the condition that the air suction flow of the other wind wheel is reduced due to overlarge negative pressure generated by one wind wheel (the axial flow wind wheel 22 or the centrifugal wind wheel 21) is avoided. Therefore, the air outlet speed of the axial flow wind wheel 22 and the air outlet speed of the centrifugal wind wheel 21 can be conveniently and independently adjusted, air supply with different speeds and different air volumes can be simultaneously realized for two different areas, multiple air outlet modes can be realized, and different air supply requirements can be met.

That is, the indoor air outlet 13 and the first air inlet 121 corresponding to the axial flow wind wheel 22 are distributed along the axial direction of the axial flow wind wheel 22, so that the air inlet direction of the indoor air outlet 13 is consistent with the air outlet direction of the first air inlet 121, the loss of the air outlet flow can be reduced, and the air outlet effect of the axial flow wind wheel 22 is ensured. The second air inlet 122 may be disposed on the front side 14, the side surface 15, or the back side 16 of the inner casing.

Referring to fig. 2 or fig. 7, in an embodiment, an indoor heat exchanger 30 is disposed on the air inlet side of the centrifugal wind wheel 21, and another indoor heat exchanger 30 is disposed on the air inlet side of the axial wind wheel 22, so that the air flows entering the axial wind wheel 22 and the centrifugal wind wheel 21 can be ensured to exchange heat effectively, and the heat exchange effect can be improved. The indoor heat exchanger 30 on the air inlet side of the centrifugal wind wheel 21 and the indoor heat exchanger 30 on the air inlet side of the axial flow wind wheel 22 can be arranged in series or in parallel.

Referring to fig. 1 and fig. 5, in an embodiment, the centrifugal wind wheel 21 includes a hub, a first blade group and a second blade group, an axis of the hub extends along a left-right direction, the first blade group and the second blade group are respectively disposed on two opposite sides of the hub in an axial direction and are both disposed on a periphery of the hub, and a side of the first blade group and a side of the second blade group away from each other form an air inlet side respectively. The axial line of centrifugal wind wheel 21 extends along left and right directions promptly, and centrifugal wind wheel 21 axial double-phase offside all is formed with the air inlet side, so can increase centrifugal wind wheel 21's air inlet rate and air output, can also reduce the condition that the air-out air current leads to the too much loss of energy because of the air current direction change between centrifugal wind wheel 21's air-out side and indoor air outlet 13. In this embodiment, the indoor air inlet 12 (the first air inlet 121) may be disposed on the front surface 14 of the inner casing, or may be disposed on the side surface 15 of the inner casing, for example, one indoor air inlet 12 may be disposed on each of the two side surfaces 15 of the inner casing. Optionally, the indoor air inlet 12 of the inner casing side 15 is elongated and extends in the up-down direction, so that the centrifugal wind wheel 21 and the axial wind wheel 22 share the indoor air inlet 12.

Referring to fig. 1 to 3, in an embodiment, the unitary air conditioner further includes an outer casing 40 and a compressor 50, the outer casing 40 is provided with an outdoor air duct, the outdoor air duct is communicated with an outdoor space, the outer casing 40 is connected to the inner casing 10, and the compressor 50 is disposed in the inner casing 10. The compressor 50 is connected to the indoor heat exchanger 30 through a refrigerant pipeline, and it should be noted that the "inner machine casing 10" and the "outer machine casing 40" in the embodiment of the present invention do not limit the installation positions of the inner machine casing 10 and the outer machine casing 40, and the integrated air conditioner may be integrally installed indoors, and at this time, both the inner machine casing 10 and the outer machine casing 40 are installed indoors. It is also possible to dispose the inner machine casing 10 indoors and to extend the outer machine casing 40 at least partially outdoors. 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. 3, 8 and 9 in combination, generally, the outer casing 40 is provided with an outdoor air outlet 42 and an outdoor air inlet 41, and both the outdoor air outlet 42 and the outdoor air inlet 41 are 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 one embodiment, the compressor 50 is located below the centrifugal wind wheel 21 and the axial flow wind wheel 22, 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 wind wheel 21 (axial wind wheel 22) and the compressor 50 may be distributed in the left-right direction or the 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 (refer to fig. 12), an axial flow fan (refer to fig. 8), 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. 10, 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 3 in combination, 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. 9 or 10, 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. 8, 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. 11 or fig. 12, 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 can be disposed on both the back surface 43 and the two side surfaces 45 of the housing, and an outdoor heat exchanger 60 can be disposed inside each outdoor air inlet 41, so as to increase the heat exchange area.
