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 indoor air inlet 12 is provided on the inner casing side surface 15, and when two or more indoor air inlets 12 are provided, at least one indoor air inlet 12 is provided on the inner casing side surface 15.

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, two indoor air inlets 12 may be disposed 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. Optionally, two indoor air outlets 13 are provided at the front face 14 of the inner shell.

In one embodiment, the two wind wheels are arranged at intervals in the vertical direction. The air inlet side of the upper wind wheel is communicated with the upper indoor air outlet 13, and the air inlet side of the lower wind wheel is communicated with the lower indoor air outlet 13. That is, the two wind wheels 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 located between two indoor air outlets 13, and the air inlet sides of the two wind wheels are both communicated with the indoor air inlet 12. Particularly, indoor air intake 12 and two indoor air outlets 13 all locate the inner shell openly 14, so set up, reduce the quantity of indoor air intake 12 on the inner machine casing 10, when simplifying the structure of inner machine casing 10, can also make the indoor air of inner machine casing 10 front side get into indoor wind channel 11 better, can reduce the possibility that indoor air intake 12 was sheltered from by indoor article, guarantee the air inlet effect.

Specifically, the indoor air outlet 13 located above is provided on the upper side of the corresponding wind wheel, and the indoor air outlet 13 located below is provided on the lower side of the corresponding wind wheel. Which is equivalent to two wind wheels positioned between 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 wind wheel 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 which has a wind wheel, 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 wind wheels are mutually independent, the air inlet flows of the two wind wheels are mutually independent in the inner machine shell 10, and the situation that the negative pressure generated by one wind wheel is too large to cause the suction flow of the other wind wheel to be reduced is avoided. Thereby can be convenient for independently adjust the air-out speed of two wind wheels 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 one embodiment, the two rotors are of the same type. It should be noted that, it is not limited herein that the two wind wheels have the same size, electrical parameters, and the like, and the two wind wheels may have the same type of wind inlet and outlet, for example, both the two wind wheels are cross-flow wind wheels, both the two wind wheels are centrifugal wind wheels, both the two wind wheels are mixed-flow wind wheels, and the like. By adopting the wind wheels of the same type, the material types of the integral air conditioner can be reduced, so that the assembly and the material management of the integral air conditioner are facilitated, and the production cost of the integral air conditioner is reduced.

And when setting up indoor air outlet 13 at the positive 14 of inner shell, can make the air-out side of through-flow wind wheel 21 just to indoor air outlet 13 setting to make the air-out air current can directly send out from indoor air outlet 13, can reduce the loss of wind speed, be favorable to increasing air supply distance. In addition, when the indoor air inlet 12 is arranged on the front surface 14 of the inner shell, the distance between the cross flow wind wheel 21 and the indoor air inlet 12 can be reduced, which is beneficial to shortening the path of the indoor air duct 11. Of course, in other embodiments, the axis of the cross-flow wind wheel 21 may be extended in the front-rear direction.

In one embodiment, one indoor air inlet 12 is provided, and the air inlet sides of the two cross flow wind wheels 21 are both communicated with the indoor air inlet 12. That is, the air inlet sides of the two cross flow wind wheels 21 share one indoor air inlet 12, so that the number of the indoor air inlets 12 on the inner machine shell 10 can be reduced, the structure of the inner machine shell 10 is facilitated to be simplified, and the production cost is reduced. Of course, in other embodiments, a plurality of indoor air inlets 12 may also be provided, and each of the plurality of indoor air inlets 12 is communicated with two cross flow wind wheels 21.

In an embodiment, an air outlet duct 17 is formed between the wind wheel and the indoor air outlet 13, and in the air outlet direction, the cross-sectional area of the air outlet duct 17 perpendicular to the air outlet direction is gradually increased. In the air-out direction, the size in air-out wind channel 17 increases gradually promptly, so can promote the diffusion effect of air-out air current to can increase the air supply scope. In the embodiment that the wind wheel is the cross flow wind wheel 21 and the axis of the cross flow wind wheel 21 extends in the left-right direction, the distance between two wind channel walls opposite to the air outlet channel 17 and parallel to the axis of the cross flow wind wheel 21 is gradually increased in the air outlet direction so as to better match with the air outlet side of the cross flow wind wheel 21, thereby better enlarging the air supply range. Of course, in other embodiments, the sizes of the air outlet duct 17 may be substantially the same.

Referring to fig. 3 or 4, when the wind wheel is a centrifugal wind wheel 22, in an embodiment, the air inlet side of the centrifugal wind wheel 22 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 22, so that the distance between the air inlet side of the centrifugal wind wheel 22 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. Of course, in other embodiments, the indoor air inlet 12 and the air inlet side of the centrifugal wind wheel 22 may be arranged at an interval in the vertical direction.

In the embodiment where the air inlet side of the centrifugal wind wheel 22 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, the indoor air inlet 12 may be disposed on the front side 14 or the back side 16 of the inner casing when the axis of the centrifugal wind wheel 22 extends in the left-right direction.

In addition, unlike the embodiment in which the air inlet side of the centrifugal wind wheel 22 is disposed toward the indoor air inlet 12, 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 22 are staggered in the front-rear direction. That is, the centrifugal wind wheel 22 is disposed 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 disposed on the inner side of the indoor air inlet 12, the indoor side heat exchanger 30 and the centrifugal wind wheel 22 are staggered in the front-rear direction, thereby avoiding the situation that the indoor side heat exchanger 30 and the centrifugal wind wheel 22 share the space of the front-rear direction of the inner casing 10, and reducing the size of the inner casing 10 in the front-rear direction.

In an embodiment, the centrifugal wind wheel 22 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 an air inlet side is respectively formed on one side of the first blade group and one side of the second blade group that are away from each other. That is, the axis of the centrifugal wind wheel 22 extends along the left and right directions, and the two opposite sides of the axial direction of the centrifugal wind wheel 22 are both formed with air inlet sides, so that the condition that the air outlet airflow between the air outlet side of the centrifugal wind wheel 22 and the indoor air outlet 13 is excessively lost due to the change of the airflow direction can be reduced, and the air inlet amount and the air outlet amount of the centrifugal wind wheel 22 can be increased. In this embodiment, the indoor air inlet 12 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. In the embodiment of two centrifugal wind wheels 22, the indoor air inlet 12 on the side surface 15 of the inner casing is a strip extending in the up-down direction, so that the air inlet sides on the same side of the two centrifugal wind wheels 22 share one indoor air inlet 12.

In one embodiment, the two rotors are of different types. The two wind wheels are of different types, which means that the two wind wheels are of different types of wind inlet and outlet, for example, please refer to fig. 5, wherein one wind wheel is a centrifugal wind wheel 22, and the other wind wheel is a cross-flow wind wheel 21. Alternatively, referring to fig. 6, one of the wind wheels is a centrifugal wind wheel 22, and the other wind wheel is an axial wind wheel 23. Or, referring to fig. 7, one of the wind wheels is a cross-flow wind wheel 21, and the other wind wheel is an axial-flow wind wheel 23, and so on. Through setting up two wind wheels that the type is different, when using integral air conditioner, can start two wind wheels simultaneously and supply air to increase the air supply amount of wind, also can select one of them air supply of two wind wheels according to the air supply needs, increased the variety of air supply mode, make integral air conditioner's application scenario wider.

Referring to fig. 5, in an embodiment, one of the wind wheels is a centrifugal wind wheel 22, and the other wind wheel is a cross-flow wind wheel 21. Therefore, when the cross flow wind wheel 21 is used for supplying wind, the cross flow wind wheel 21 can be ensured to supply wind uniformly, and the requirement of a user on the uniformity of the supplied wind can be better met. When the air is supplied through the centrifugal wind wheel 22, the air supply distance of the centrifugal wind wheel 22 can be ensured to be long. And centrifugal wind wheel 22 operates steadily, can the noise reduction, when using in activity board house or container room, can reduce the vibration of integral air conditioner to can reduce the mutual vibration friction between integral air conditioner and the wall body and produce the noise. When the cross flow wind wheel 21 and the centrifugal wind wheel 22 supply wind simultaneously, the wind supply uniformity and the wind supply distance can be achieved.

The arrangement of the cross-flow wind wheel 21 and the centrifugal wind wheel 22 in the inner machine shell 10 has various modes, for example, in one embodiment, the cross-flow wind wheel 21 is positioned above the centrifugal wind wheel 22. That is, the centrifugal wind wheel 22 is disposed below the cross flow wind wheel 21, so that in the cooling mode, main air supply can be performed through the cross flow wind wheel 21, and uniformity of sending out cold air flow can be ensured. In the heating mode, the centrifugal wind wheel 22 can be used for supplying air mainly, so that the air supply distance of hot air flow is long. Furthermore, in one embodiment, the centrifugal wind wheel 22 is located above the cross-flow wind wheel 21. That is, the cross-flow wind wheel 21 is arranged below the centrifugal wind wheel 22, so that in the cooling mode, main air supply can be performed through the centrifugal wind wheel 22 to ensure that the air supply distance of the cold air flow is longer. In the heating mode, the main air supply can be carried out through the cross flow wind wheel 21 so as to ensure the uniformity of hot air flow.

Referring to fig. 6, in another embodiment, one of the wind wheels is a centrifugal wind wheel 22, and the other wind wheel is an axial wind wheel 23. Thus, 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 23. When the air needs to be supplied to a remote place, the main air supply can be performed through the centrifugal wind wheel 22, so that the outlet air flow can be supplied to a remote place. And the centrifugal wind wheel 22 and the axial flow wind wheel 23 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. Therefore, the integral air conditioner can realize various air supply modes, the diversity of the air supply modes is increased, and the application scene of the integral air conditioner is wider. And centrifugal wind wheel 22 operates steadily, can the noise reduction, when using in activity board house or container room, can reduce the vibration of integral air conditioner to can reduce the mutual vibration friction between integral air conditioner and the wall body and produce the noise.

There are various ways of disposing axial flow wind wheel 23 and centrifugal wind wheel 22 in inner machine shell 10, for example, in an embodiment, axial flow wind wheel 23 is disposed at intervals below centrifugal wind wheel 22. That is, the centrifugal wind wheel 22 is arranged above the axial flow wind wheel 23, so that in the cooling mode, main air supply can be performed through the centrifugal wind wheel 22 to ensure that the air supply distance of the cold air flow is long. In the heating mode, the axial flow wind wheel 23 can be used for mainly supplying air so as to ensure that the air quantity of hot air flow is larger and realize indoor rapid temperature rise. In addition, in one embodiment, axial flow wind wheel 23 is spaced above centrifugal wind wheel 22. That is, the centrifugal wind wheel 22 is arranged below the axial flow wind wheel 23, so that main air supply can be performed through the axial flow wind wheel 23 in the refrigeration mode, the air quantity of cold air flow is large, and indoor rapid cooling is realized. In the heating mode, the centrifugal wind wheel 22 can be used for supplying air mainly, so that the air supply distance of hot air flow is long.

In an embodiment where one of the wind wheels is a centrifugal wind wheel 22, and the other wind wheel is an axial flow wind wheel 23, optionally, an indoor air outlet 13 corresponding to the axial flow wind wheel 23 (i.e., the indoor air outlet 13 communicated with the axial flow wind wheel 23) is disposed on the front surface 14 of the inner casing, an indoor air inlet 12 corresponding to the axial flow wind wheel 23 (i.e., the indoor air inlet 12 communicated with the axial flow wind wheel 23) is disposed on the back surface 16 of the inner casing, an air outlet side of the axial flow wind wheel 23 faces the indoor air outlet 13, and an air inlet side of the axial flow wind wheel 23 faces the indoor air inlet 12. That is, the indoor air outlet 13 and the indoor air inlet 12 corresponding to the axial flow wind wheel 23 are distributed along the axial direction of the axial flow wind wheel 23, so that the air inlet and outlet directions of the indoor air outlet 13 and the indoor air inlet 12 corresponding to the axial flow wind wheel 23 are relatively consistent, the loss of the air outlet flow can be reduced, and the air outlet effect of the axial flow wind wheel 23 is ensured.

Further, in an embodiment, the air inlet side of the centrifugal wind wheel 22 is provided with an indoor side heat exchanger 30, and the air inlet side of the axial wind wheel 23 is provided with another indoor side heat exchanger 30, so that the arrangement can ensure that the air flow entering the axial wind wheel 23 and the centrifugal wind wheel 22 can be effectively exchanged heat, and the heat exchange effect can be improved. The indoor heat exchanger 30 on the air inlet side of the centrifugal wind wheel 22 and the indoor heat exchanger 30 on the air inlet side of the axial wind wheel 23 can be arranged in series or in parallel.

Further, in an embodiment, an air outlet duct 17 is formed between the centrifugal wind wheel 22 and the indoor air outlet 13, and in the air outlet direction, the air outlet duct 17 gradually inclines towards a direction away from the axial wind wheel 23. 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 22 is disposed above the axial wind wheel 23, that is, the wind 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 22 is arranged below the axial wind wheel 23, 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.

Referring to fig. 7, in another embodiment, one of the wind wheels is an axial flow wind wheel 23, and the other wind wheel is a cross flow wind wheel 21, so that when the unitary air conditioner is used, if the requirement on the uniformity of the supplied air is strict, the main supplied air can be supplied by the cross flow wind wheel 21. And if the air supply with large air volume is needed, the main air supply can be carried out through the axial flow wind wheel 23. The cross flow wind wheel 21 and the axial flow wind wheel 23 can be started to supply air at the same time, so that the air supply volume of the integral air conditioner can be increased. Therefore, the integral air conditioner can realize various air supply modes, the diversity of the air supply modes is increased, and the application scene of the integral air conditioner is wider.

The tubular wind wheel 21 and the axial wind wheel 23 are disposed in various ways in the inner machine casing 10, for example, in an embodiment, the axial wind wheel 23 is disposed at an interval below the tubular wind wheel 21. That is, the cross-flow wind wheel 21 is arranged above the axial-flow wind wheel 23, so that in the cooling mode, main air supply can be performed through the cross-flow wind wheel 21 to ensure the uniformity of sending out cold air flow. In the heating mode, the axial flow wind wheel 23 can be used for mainly supplying air so as to ensure that the air quantity of hot air flow is larger and realize indoor rapid temperature rise. In addition, in one embodiment, the axial flow wind wheel 23 is arranged above the cross flow wind wheel 21 at intervals. That is, the cross flow wind wheel 21 is arranged below the axial flow wind wheel 23, so that main air supply can be performed through the axial flow wind wheel 23 in a refrigeration mode, the air quantity of cold air flow is large, and indoor rapid cooling is realized. In the heating mode, the main air supply can be carried out through the cross flow wind wheel 21 so as to ensure the uniformity of hot air flow.

Further, in an embodiment, an air outlet duct 17 is formed between the cross flow wind wheel 21 and the indoor air outlet 13, and in the air outlet direction, the air outlet duct 17 gradually inclines towards a direction away from the axial flow wind wheel 23. 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 cross flow wind wheel 21 is disposed above the axial flow wind wheel 23, that is, the air outlet duct 17 extends obliquely upward, so that the air flow 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 refrigeration mode. When the cross flow wind wheel 21 is arranged below the axial flow wind wheel 23, 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 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.

Referring to fig. 1 and 2, 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 back surface 16 of 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 pipe. It should be noted that "the inner machine casing 10" and "the outer machine casing 40" in the embodiment of the present invention are not limited to the installation positions of the inner machine casing 10 and the outer machine casing 40, and the integral air conditioner may be installed indoors as a whole, and at this time, the inner machine casing 10 and the outer machine casing 40 are both 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. 2, 8 and 9, 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 one embodiment, the compressor 50 is located below the two wind wheels, 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 two wind wheels 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 (refer to fig. 12), an axial flow fan (refer to fig. 8), a cross flow fan, or the like. The compressor 50 is connected to the indoor heat exchanger 30 and the outdoor heat exchanger 60 by refrigerant lines.

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 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. 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 that the outdoor air outlet 42 is 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 side surfaces 45 of the housing, and the outdoor air inlet 41 is disposed on the back surface 43 of the housing, so that the possibility that the outdoor air outlet 42 is blocked 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 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.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
