There is also a mobile air conditioner on the market. Although it is easy to install, the current mobile air conditioner has a single air supply method and is difficult to meet the needs of different scenarios. Summary of the invention

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] The present invention provides an integrated air conditioner, which can be used in a mobile house or a container house, and of course, can also be used in a commercial house.

[0041] In the embodiment of the present invention, please refer to reference bodies 1 to Figure 3 The integrated air conditioner includes an inner machine casing 10, a centrifugal fan wheel 21 and an axial flow fan wheel 22. The inner machine casing 10 is provided with an indoor air duct 11, an indoor air inlet 12 and an indoor air outlet 13. The indoor air inlet 12 and the indoor air outlet 13 are both connected to the indoor air duct 11. The centrifugal fan wheel 21 and the axial flow fan wheel 22 are both arranged in the indoor air duct 11.

[0042] Usually, the inner machine casing 10 is arranged indoors, that is, the indoor air inlet 12 and the indoor air outlet 13 are both connected to the indoor space, so that the indoor air can be heat exchanged. Of course, the installation position of the inner machine casing 10 is not limited here. For example, the inner machine casing 10 can also be arranged outdoors, so that the indoor air inlet 12 and the indoor air outlet 13 are both connected to the indoor space.

[0043] The technical solution of the present invention is provided with a centrifugal fan wheel 21 and an axial flow fan wheel 22 in the inner machine casing 10. When the integral air conditioner is used, if a large amount of air is required, the axial flow fan wheel 22 can be used for the main air supply. When air needs to be supplied to a distant place, the centrifugal fan wheel 21 can be used for the main air supply so that the air flow can be delivered to a distant place. Moreover, the centrifugal fan wheel 21 and the axial flow fan wheel 22 can be started at the same time to supply air, so that when the demand for large amount of air is met, the demand for long-distance air supply can also be met. In this way, the integral air conditioner can realize a variety of air supply modes, increase the diversity of air supply modes, and make the applicable scenes of the integral air conditioner wider. Moreover, the centrifugal fan wheel 21 runs smoothly and can reduce noise. When used in a mobile board house or a container house, it can reduce the vibration of the integral air conditioner, thereby reducing the noise generated by the mutual vibration and friction between the integral air conditioner and the wall.

[0044] In one embodiment, the inner machine casing 10 is provided with two indoor air outlets 13, the two indoor air outlets 13 are spaced apart, the air outlet side of the centrifugal wind wheel 21 is connected to one of the indoor air outlets 13, and the air outlet side of the axial flow wind wheel 22 is connected to the other indoor air outlet 13. That is, each indoor air outlet 13 can supply air independently, thus increasing the air outlet position on the inner machine casing 10 and increasing the air supply range. For example, when the two indoor air outlets 13 are spaced apart in the up and down directions, the air supply range in the up and down directions can be increased, and when the two indoor air outlets 13 are spaced apart in the left and right directions, the air supply range in the left and right directions can be increased. Of course, in other embodiments, only one indoor air outlet 13 may be provided, and the air outlet side of the centrifugal wind wheel 21 and the air outlet side of the axial flow wind wheel 22 are both connected to the indoor air outlet 13.

[0045] The inner housing has an inner housing front 14, an inner housing back 16 and two inner housing side surfaces 15, the inner housing front 14 is opposite to the inner housing back 16, the two inner housing side surfaces 15 are opposite, and each inner housing side surface 15 is located between the inner housing front 14 and the inner housing back 16. Usually, when the integral air conditioner is in use, for example, when the integral air conditioner is placed against a wall, the inner housing back 16 faces the wall. The following description is made by taking the inner housing front 14 as the front, the inner housing back 16 as the rear, and the two inner housing side surfaces 15 as the left and right as an example.

[0046] In one embodiment, at least one indoor air outlet 13 is disposed on the front side 14 of the inner shell, that is, the indoor air outlet 13 is disposed on the front side of the integral air conditioner, so that the air flow can be easily directed to the front and left and right sides of the integral air conditioner, which can increase the air supply range of the integral air conditioner and reduce the possibility of the indoor air outlet 13 being blocked by indoor objects. Among them, both indoor air outlets 13 can be disposed on the front side 14 of the inner shell, or one of the indoor air outlets 13 can be disposed on the front side 14 of the inner shell, and the other indoor air outlet 13 can be disposed on the side 15 of the inner shell. Of course, in other embodiments, both indoor air outlets 13 can also be disposed on the side 15 of the inner shell.

[0047] There are many locations for the indoor air inlet 12. For example, in one embodiment, at least one indoor air inlet 12 is disposed on the front side 14 of the inner shell of the inner machine casing 10. That is, when there is one indoor air inlet 12, the indoor air inlet 12 is disposed on the front side 14 of the inner shell. When there are two or more indoor air inlets 12, at least one indoor air inlet 12 is disposed on the front side 14 of the inner shell. The indoor air inlet 12 is also disposed on the front side of the integral air conditioner, which can reduce the possibility of the indoor air inlet 12 being blocked by indoor objects and ensure the air intake effect. Among them, both indoor air inlets 12 can be disposed on the front side 14 of the inner shell; or one of the indoor air outlets 13 can be disposed on the front side 14 of the inner shell, and the other indoor air outlet 13 can be disposed on the side 15 of the inner shell; or one of the indoor air outlets 13 can be disposed on the front side 14 of the inner shell, and the other indoor air outlet 13 can be disposed on the back side 16 of the inner shell.

[0048] In another embodiment, at least one indoor air inlet 12 is provided on the inner shell side 15 of the inner machine casing 10. That is, when there is one indoor air inlet 12, the air inlet is provided on the inner shell side 15, and when there are two or more indoor air inlets 12, at least one indoor air inlet 12 is provided on the inner shell side 15. When the indoor air outlet 13 is provided on the inner shell front 14, the indoor air outlet 13 and the indoor air inlet 12 are spaced far apart, and the indoor air outlet 13 and the indoor air inlet 12 face different directions, which can reduce the possibility that the airflow blown out from the indoor air outlet 13 is directly sucked into the indoor air inlet 12, and can also improve the circulation effect of the indoor air, and realize the full circulation heat exchange of the indoor air. The two indoor air inlets 12 may be arranged on the inner shell side 15. In this case, an indoor air inlet 12 may be arranged on each of the two sides of the inner machine casing 10, and the two indoor air ducts 11 are connected to the two indoor air inlets 12 in a one-to-one correspondence. Alternatively, two indoor air inlets 12 may be arranged on each inner shell side 15, and each of the two inner shell side 15 has an indoor air inlet 12 connected to one of the indoor air ducts 11, while the other indoor air inlet 12 on the two inner shell side 15 is connected to the other indoor air duct 11. Alternatively, one of the indoor air outlets 13 may be arranged on the inner shell side 15, and the other indoor air outlet 13 may be arranged on the inner shell back 16.

[0049] In another embodiment, all indoor air inlets 12 may be arranged on the back side 16 of the inner shell. That is, when there is one indoor air inlet 12, the indoor air inlet 12 is arranged on the back side 16 of the inner shell, and when there are two or more indoor air inlets 12, all indoor air inlets 12 are arranged on the back side 16 of the inner shell. When the indoor air outlet 13 is arranged on the front side 14 of the inner shell, the indoor air outlet 13 and the indoor air inlet 12 are spaced far apart, and the indoor air outlet 13 and the indoor air inlet 12 face different directions, which can reduce the possibility that the airflow blown out from the indoor air outlet 13 is directly sucked into the indoor air inlet 12, and can also improve the circulation effect of the indoor air, and realize the full circulation and heat exchange of the indoor air.

[0050] In one embodiment, two indoor air outlets 13 are arranged at intervals in the vertical direction. With such arrangement, the indoor air outlet 13 can be reasonably selected to discharge air according to the heat exchange mode to achieve a better air supply effect and improve the indoor heat exchange effect. For example, in the heating mode, since the hot air flow will flow upward after being sent out from the indoor air outlet 13, air can be supplied through the indoor air outlet 13 below, so that the hot air flow is sent downward as much as possible, so that the hot air flow can be better distributed indoors. In the cooling mode, since the cold air flow will flow downward after being sent out from the indoor air outlet 13, air can be supplied through the indoor air outlet 13 above, so that the cold air flow is sent upward as much as possible, so that the cold air flow can be better distributed indoors. Moreover, the two indoor air outlets 13 are both arranged on the front side 14 of the inner shell, which increases the air supply range in the vertical direction while making the air supply range in the left and right directions larger. Of course, in other embodiments, the two indoor air outlets 13 can also be distributed at intervals in the left and right directions. Or the two indoor air outlets 13 are arranged on the two inner shell side surfaces 15.

[0051] 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 wheel 21 are arranged in the vertical direction, which can reduce the size of the inner machine casing 10 in the left-right direction and the front-back direction, thereby reducing the occupied area of ​​the inner machine casing 10 in the room. In addition, the upper indoor air outlet 13 can be placed in 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 can also be arranged at intervals in the left-right direction.

[0052] There are many ways to arrange the axial flow fan wheel 22 and the centrifugal fan wheel 21 in the inner machine housing 10. For example, in one embodiment, the axial flow fan wheel 22 is arranged below the centrifugal fan wheel 21. That is, the centrifugal fan wheel 21 is arranged above the axial flow fan wheel 22. In this way, in the cooling mode, the centrifugal fan wheel 21 can be used for the main air supply to ensure that the air supply distance of the cold air flow is relatively long. In the heating mode, the axial flow fan wheel 22 can be used for the main air supply to ensure that the air volume of the hot air flow is large, so as to achieve rapid indoor temperature rise.

[0053] In another embodiment, the axial flow fan wheel 22 is arranged above the centrifugal fan wheel 21. That is, the centrifugal fan wheel 21 is arranged below the axial flow fan wheel 22. In this way, in the cooling mode, the axial flow fan wheel 22 can be used for main air supply to ensure that the air volume of the cold air flow is large and the indoor temperature is quickly reduced. In the heating mode, the centrifugal fan wheel 21 can be used for main air supply to ensure that the hot air flow has a long air supply distance.

[0054] In one embodiment, the indoor air outlet 13 connected to the air outlet side of the centrifugal wind wheel 21 is located on the side of the centrifugal wind wheel 21 away from the axial flow wind wheel 22. That is, when the centrifugal wind wheel 21 is located above the axial flow 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 flow wind wheel 22, the indoor air outlet 13 corresponding to the centrifugal wind wheel 21 is located below the centrifugal wind wheel 21. In this way, the distance between the two indoor air outlets 13 can be larger, thereby increasing the air supply range. In the embodiment where the indoor air inlet 12 is located between the two indoor air outlets 13, this can also reduce the possibility that the air flow sent from the indoor air outlet 13 is directly sucked into the indoor air inlet 12. Of course, in other embodiments, in the up and down directions, the two indoor air outlets 13 can also be arranged between the two wind wheels.

[0055] 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 tilts in the direction away from the axial flow wind wheel 22. In this way, the distance between the two indoor air outlets 13 can be farther, so that the air supply range can be further increased. For example, when the centrifugal wind wheel 21 is arranged 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 upper indoor air outlet 13 can be sent to a higher position in the room, 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, that is, the air outlet duct 17 extends obliquely downward, so that the airflow sent out from the lower indoor air outlet 13 can be better sent to the bottom surface, which is beneficial to improving the air supply effect in the heating mode. In the embodiment where the indoor air inlet 12 is located between the two indoor air outlets 13, the outlet air flow is sent out obliquely upward and obliquely downward, which can further reduce the possibility that the outlet air flow sent out from the indoor air outlet 13 is directly sucked into the indoor air inlet 12. Of course, in other embodiments, the extension direction of the outlet duct 17 can also be perpendicular to the front surface 14 of the inner shell.

[0056] There are many ways to install the centrifugal fan wheel 21. For example, in one embodiment, the axis of the centrifugal fan wheel 21 extends in the front-to-back direction. That is, the air inlet side of the centrifugal fan wheel 21 is arranged toward the front side or the rear side of the inner casing 10, so that the space in the left-right direction and the up-down direction of the inner casing 10 can be fully utilized, so that the radial dimension of the centrifugal fan wheel 21 is larger, thereby increasing the air supply of the centrifugal fan wheel 21. At the same time, the axial dimension of the centrifugal fan wheel 21 is smaller, which can reduce the dimension of the inner casing 10 in the front-to-back direction. In the embodiment in which the air inlet side of the centrifugal fan wheel 21 is arranged toward the indoor air inlet 12, that is, the indoor air inlet 12 can be arranged on the front side 14 of the inner casing or the back side 16 of the inner casing. In this embodiment, the indoor air outlet 13 is arranged on the front side 14 of the inner casing. Of course, in other embodiments, when the axis of the centrifugal fan wheel 21 extends in the front-to-back direction, the indoor air inlet 12 can also be arranged on the side 15 of the inner casing.

[0057] Please refer to Figures 4 to 6In another embodiment, the axis of the centrifugal fan wheel 21 extends in the left-right direction. That is, the air inlet side of the centrifugal fan wheel 21 is arranged toward the left or right side of the inner machine casing 10. It should be understood that the air inlet side of the centrifugal fan wheel 21 is located on the axial side, and the air outlet side of the centrifugal fan wheel 21 is located on the circumferential surface. Therefore, when arranged in this way, the air outlet side of the centrifugal fan wheel 21 can be directed toward the outdoor air outlet 42 of the front side 14 of the inner casing, so that the airflow sent out from the air outlet side of the centrifugal fan wheel 21 can be directly sent out from the outdoor air outlet 42, reducing the situation where the air outlet airflow is sent out from the air outlet side of the centrifugal fan wheel 21. Turning, thereby reducing the situation where the air outlet airflow is excessively lost between the air outlet side of the centrifugal fan wheel 21 and the indoor air outlet 13 due to the change of airflow direction, which is conducive to increasing the air supply distance. In the embodiment where the air inlet side of the centrifugal fan wheel 21 is arranged toward the indoor air inlet 12, that is, the indoor air inlet 12 is arranged on the side surface 15 of the inner casing. 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 shell.

[0058] In one embodiment, there is one indoor air inlet 12, and the air inlet sides of the centrifugal wind wheel 21 and the axial flow wind wheel 22 are both connected to 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. Such an arrangement reduces the number of indoor air inlets 12 on the inner machine casing 10, which is conducive to simplifying the structure of the inner machine casing 10 and reducing production costs. Of course, in other embodiments, one indoor air inlet 12 may be provided on the inner machine casing 10 corresponding to the axial flow wind wheel 22 and the centrifugal wind wheel 21.

[0059] Furthermore, in one embodiment, the integrated air conditioner further includes an indoor heat exchanger 30, which is arranged at the indoor air inlet 12. That is, the indoor heat exchanger 30 is arranged 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, it first passes through the indoor heat exchanger 30 for heat exchange. The air after heat exchange is then sucked in by the axial flow wind wheel 22 and the centrifugal wind wheel 21 respectively, and is respectively sent out by the axial flow wind wheel 22 and the centrifugal wind wheel 21. In this way, the axial flow wind wheel 22 and the centrifugal wind wheel 21 share one indoor heat exchanger 30, which can reduce the number of indoor heat exchangers 30 and the assembly process of the indoor heat exchanger 30, which is conducive to reducing production costs. Of course, in other embodiments, the indoor heat exchanger 30 can also be arranged at the indoor air outlet 13. Or an indoor heat exchanger 30 is provided on the air inlet side of the axial flow wind wheel 22 and the centrifugal wind wheel 21.

[0060] Please refer to Figure 3 or Figure 5There are many matching positions between the centrifugal wind wheel 21 and the indoor air inlet 12. For example, in one embodiment, the air inlet side of the centrifugal wind wheel 21 is arranged toward the indoor air inlet 12. That is, the indoor air inlet 12 is arranged at the position of the inner 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 conducive to shortening the air inlet path and shortening the air duct path between the indoor air inlet 12 and the indoor air outlet 13. When the indoor heat exchanger 30 is arranged at the indoor air inlet 12, the air inlet side of the centrifugal wind wheel 21 faces the inner side 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 can also be arranged at intervals in the vertical direction.

[0061] In another embodiment, the indoor air inlet 12 is provided on the front face 14 of the inner shell, and the indoor air inlet 12 is offset from the centrifugal fan wheel 21 in the front-to-back direction. That is, the orthographic projection of the centrifugal fan wheel 21 on the front face 14 of the inner shell is arranged at a distance from the indoor air inlet 12, so when the indoor heat exchanger 30 is provided inside the indoor air inlet 12, the indoor heat exchanger 30 is also offset from the centrifugal fan wheel 21 in the front-to-back direction, thereby avoiding the situation where the indoor heat exchanger 30 and the centrifugal fan wheel 21 share the space in the front-to-back direction of the inner machine casing 10, and reducing the size of the inner machine casing 10 in the front-to-back direction.

[0062] In another embodiment, the indoor air inlet 12 is located between the centrifugal wind wheel 21 and the axial flow wind wheel 22, and the centrifugal wind wheel 21 and the axial flow wind wheel 22 are both spaced apart 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 arranged on the front face 14 of the inner shell, and the centrifugal wind wheel 21 and the axial flow wind wheel 22 are both staggered from the indoor air inlet 12 in the front-to-back direction. That is, the orthographic projection of the centrifugal wind wheel 21 on the front face 14 of the inner shell is spaced apart from the indoor air inlet 12, and the orthographic projection of the axial flow wind wheel 22 on the front face 14 of the inner shell is also spaced apart from the indoor air inlet 12. When the indoor heat exchanger 30 is provided on the inner side of the indoor air inlet 12, the centrifugal wind wheel 21 and the axial flow wind wheel 22 are spaced apart from the indoor heat exchanger 30 in the vertical direction, thereby avoiding the situation where the indoor heat exchanger 30 and the centrifugal wind wheel 21, and the indoor heat exchanger 30 and the axial flow wind wheel 22 share the space in the front-to-back direction of the inner machine casing 10, and reducing the size of the inner machine casing 10 in the front-to-back direction. Of course, in other embodiments, the indoor air inlet 12 may also be provided on the left or right side of the centrifugal wind wheel 21. Or the indoor air inlet 12 may be provided on the side surface 15 of the inner casing. In addition, in the vertical direction, only the centrifugal wind wheel 21 or the axial flow wind wheel 22 may be spaced apart from the indoor air inlet 12. In addition, in the vertical direction, the centrifugal wind wheel 21 and the axial flow wind wheel 22 may also partially overlap or completely overlap with the indoor air inlet 12.

[0063] Please refer to Figure 7In one embodiment, the indoor air duct 11 includes a first air duct 111 and a second air duct 112 that are independent of each other, wherein one indoor air outlet 13 is connected to the first air duct 111, and the other indoor air outlet 13 is connected to the second air duct 112, and the indoor air inlet 12 includes a first air inlet 121 connected to the first air duct 111 and a second air inlet 122 connected to the second air duct 112, and the axial flow wind wheel 22 is arranged in the first air duct 111, and the centrifugal wind wheel 21 is arranged in the second air duct 112. In this way, the axial flow wind wheel 22 and the centrifugal wind wheel 21 can be ensured to be independent of each other, thereby ensuring that the air intake airflows of the axial flow wind wheel 22 and the centrifugal wind wheel 21 are independent of each other in the inner machine casing 10, and avoiding the situation where the negative pressure generated by one of the wind wheels (axial flow wind wheel 22 or centrifugal wind wheel 21) is too large, resulting in a reduction in the air intake airflow of the other wind wheel. Thus, it is convenient to independently adjust the air outlet speed of the axial flow wind wheel 22 and the centrifugal wind wheel 21, so as to realize air supply of different speeds and different air volumes to two different areas at the same time, and realize multiple air outlet modes to meet different air supply requirements. Among them, the indoor air outlet 13 of the first air duct 111 and the indoor air outlet 13 of the second air duct 112 can be both arranged on the front face 14 of the inner shell, or can be both arranged on the side face 15 of the same inner shell, or the indoor air outlet 13 of the first air duct 111 and the indoor air outlet 13 of the second air duct 112 can be arranged on two side faces 15 of the inner shell, or the indoor air outlet 13 of the first air duct 111 (the second air duct 112) can be arranged on the front face 14 of the inner shell, and the indoor air outlet 13 of the second air duct 112 (the first air duct 111) can be arranged on the side face 15 of the inner shell.

[0064] In one embodiment, the indoor air outlet 13 connected to the first air duct 111 is arranged on the front side 14 of the inner shell of the inner machine housing, the first air inlet 121 is arranged on the back side 16 of the inner shell, the air outlet side of the axial flow wind wheel 22 faces the indoor air outlet 13, and the air inlet side of the axial flow wind wheel 22 faces the first air inlet 121. 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 and the air outlet direction of the first air inlet 121 are relatively consistent, the loss of the air outlet airflow can be reduced, and the air outlet effect of the axial flow wind wheel 22 is ensured. Among them, the second air inlet 122 can be arranged on the front side 14, the side 15 or the back side 16 of the inner shell.

[0065] Please refer to Figure 2 or Figure 7 In one embodiment, an indoor heat exchanger 30 is provided on the air inlet side of the centrifugal wind wheel 21, and another indoor heat exchanger 30 is provided on the air inlet side of the axial flow wind wheel 22. Such an arrangement can ensure that the airflows entering the axial flow wind wheel 22 and the centrifugal wind wheel 21 are effectively exchanged with heat, thereby improving the heat exchange effect. The refrigerant pipelines of 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.

[0066] Please refer to Figure 1 and Figure 5 In one embodiment, the centrifugal wind wheel 21 includes a hub, a first blade group and a second blade group. The axis of the hub extends in the left-right direction. The first blade group and the second blade group are arranged on two opposite sides of the hub in the axial direction and are arranged on the periphery of the hub. The first blade group and the second blade group are arranged on the side away from each other to form an air inlet side. That is, the axis of the centrifugal wind wheel 21 extends in the left-right direction, and the two opposite sides of the axial direction of the centrifugal wind wheel 21 are formed with air inlet sides. In this way, the air intake and air outlet of the centrifugal wind wheel 21 can be increased, and the situation that the air flow changes between the air outlet side of the centrifugal wind wheel 21 and the indoor air outlet 13 due to excessive energy loss caused by the change of airflow direction can be reduced. In this embodiment, the indoor air inlet 12 (first air inlet 121) can be arranged on the front side 14 of the inner shell, and can also be arranged on the side 15 of the inner shell. For example, an indoor air inlet 12 can be provided on each of the two inner shell side 15. Optionally, the indoor air inlet 12 of the inner shell side surface 15 is in the shape of a long strip extending in the up-down direction, so that the centrifugal wind wheel 21 and the axial flow wind wheel 22 share the indoor air inlet 12 .

[0067] Please refer to Figures 1 to 3 In one embodiment, the integrated air conditioner further includes an outer casing 40 and a compressor 50. The outer casing 40 is provided with an outdoor air duct, which is connected to the outdoor space. The outer casing 40 is connected to the inner casing 10, and the compressor 50 is arranged in the inner casing 10. The compressor 50 is connected to the indoor heat exchanger 30 through a refrigerant pipeline. It should be noted that the "inner casing 10" and the "outer casing 40" in the embodiment of the present invention do not limit the installation positions of the inner casing 10 and the outer casing 40. The integrated air conditioner can be installed indoors as a whole. In this case, the inner casing 10 and the outer casing 40 are both installed indoors. The inner casing 10 can also be arranged indoors, and the outer casing 40 can be at least partially extended to the outdoors. In order to allow the external unit casing 40 to extend outdoors, a mounting opening is usually provided on the wall so that the external unit casing 40 can extend outdoors from the mounting opening. In this case, the space between the inner surface of the wall and the outer surface of the wall (the mounting opening) can be regarded as outdoors, that is, the space within the inner surface of the wall can be regarded as indoors, and the space outside the inner surface of the wall can be regarded as outdoors.

[0068] Please refer to Figure 3 , Figure 8 and Fig. 9Typically, 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 connected to the outdoor air duct and are connected to the outdoor space. Among them, the outdoor air outlet 42 and the outdoor air inlet 41 can be directly connected to the outdoors, or can be connected to the outdoors through a connecting pipe. For example, when the integral air conditioner is placed indoors as a whole (that is, the outer casing 40 is placed indoors), the outdoor air outlet 42 can be connected to the outdoors through a connecting pipe, and the outdoor air inlet 41 can be connected to the outdoors through another connecting pipe. It is also possible to partially extend the outer casing 40 to the outdoors, and expose the outdoor air outlet 42 and the outdoor air inlet 41 to the outdoors.

[0069] When installing the integrated air conditioner, the inner housing 10 and the compressor 50 can be placed indoors, and the outer housing 40 can be extended outdoors. By arranging the compressor 50 in the inner housing 10, the overall weight of the outer housing 40 is reduced, so that when the outer housing 40 is installed on the second floor or above of the house, the pressure of the outer housing 40 on the support frame can be reduced. For example, when the integrated air conditioner is used in a two-story or more movable board house (container house), the pressure on the support frame can be reduced by installing the outer housing 40 outdoors, and when the outer housing 40 is connected to the inner housing 10, it is not even necessary to set a support frame to support the outer housing 40, which can be convenient for use in a movable board house or a container house. Of course, in other embodiments, the compressor 50 can also be arranged in the outer housing 40.

[0070] In one embodiment, the compressor 50 is located below the centrifugal fan wheel 21 and the axial flow fan wheel 22, so that the center of gravity of the inner machine casing 10 is lower, which can improve the stability of the inner machine casing 10 when placed. Of course, in other embodiments, the centrifugal fan wheel 21 (axial flow fan wheel 22) and the compressor 50 can also be distributed in the left-right direction or the front-back direction.

[0071] In one embodiment, the integrated air conditioner further includes an isolation cover 70, which is disposed in the inner machine casing 10 and covers the compressor 50. In this way, the isolation cover 70 can separate the space where the compressor 50 is located from other inner cavities of the inner machine casing 10, and can reduce the heat and noise generated by the compressor 50 from radiating into the room. In order to improve the heat insulation effect of the isolation cover 70, the isolation cover 70 is made of a heat insulation material. In order to improve the effect of the isolation cover 70 in blocking compression noise, the isolation cover 70 is made of a sound insulation material.

[0072] Typically, the integrated air conditioner further includes an outdoor fan 80 and an outdoor heat exchanger 60, both of which are arranged in the outdoor air duct. The outdoor fan 80 may be a centrifugal fan (see Fig.12 ), axial flow fan (reference Figure 8) or a cross-flow fan, etc., the compressor 50 is connected to the indoor heat exchanger 30 and the outdoor heat exchanger 60 through a refrigerant pipeline.

[0073] In one embodiment, the outdoor heat exchanger 60 is arranged on the air inlet side of the outdoor fan 80. That is, the outdoor heat exchanger 60 is arranged between the air inlet side of the outdoor fan 80 and the outdoor air inlet 41. When the outdoor air enters from the outdoor air inlet 41, it first passes through the outdoor heat exchanger 60 for heat exchange, and then passes through the outdoor fan 80 and the outdoor air outlet 42 to be discharged to the outdoor space. In this way, dust accumulation on the inside of the outdoor heat exchanger 60 can be reduced, and on rainy days, the possibility of water entering the outer casing 40 can be reduced, thereby improving safety. When arranged in this way, multiple outdoor air inlets 41 can also be arranged on the outer casing 40, and an outdoor heat exchanger 60 is arranged on the inner side of each outdoor air inlet 41, so as to increase the heat exchange effect.

[0074] Please refer to Fig.10 In one embodiment, the outdoor heat exchanger 60 is disposed on the 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. When the outdoor air enters from the outdoor air inlet 41, it first passes through the outdoor fan 80, and then passes through the outdoor heat exchanger 60 and the outdoor air outlet 42 in sequence to be discharged to the outdoor space. In this way, in the cooling mode, the outdoor airflow passing through the outdoor fan 80 is an airflow without heat exchange, which is conducive to heat dissipation of the outdoor fan 80.

[0075] Please refer to Figure 1 and Figure 3 The outer casing 40 has a casing back surface 43, a casing top surface 44 and two casing side surfaces 45. The casing back surface 43 is the surface of the outer casing 40 away from the inner casing 10. There are many positions of the outdoor air inlet 41 and the outdoor air outlet 42. For example, please refer to Fig. 9 or Fig.10 In one embodiment, the outdoor air outlet 42 is arranged on the back 43 of the housing, and the outdoor air inlet 41 is arranged on the side 45 of the housing. By arranging the outdoor air outlet 42 on the back 43 of the housing, the outdoor air outlet 42 is away from the wall, which can reduce the possibility of the air outlet being blocked and ensure the air outlet effect. The outdoor air inlet 41 can be arranged on one side 45 of the housing, or one outdoor air inlet 41 can be arranged on each of the two side 45 of the housing.

[0076] In addition, please refer to Figure 8 In one embodiment, the outdoor air outlet 42 is disposed on one of the housing sides 45, and the outdoor air inlet 41 is disposed on the housing back 43, which can also reduce the possibility of the air outlet being blocked and ensure the air outlet effect. In this embodiment, another outdoor air inlet 41 can also be disposed on the other housing side 45.

[0077] Also, please refer to Fig.11 or Fig.12 In one embodiment, the outdoor air outlet 42 is arranged on the top surface 44 of the outer shell, and the outdoor air inlet 41 is arranged on the side surface 45 of the outer shell or the back surface 43 of the outer shell. In this way, the outdoor air inlet 41 can be arranged on the back surface 43 of the outer shell and the two side surfaces 45 of the outer shell, and an outdoor heat exchanger 60 can be arranged on the inner side of each outdoor air inlet 41, which can increase the heat exchange area.

[0078] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
