When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] like Figures 1 to 6 As shown, the integrated air conditioner 100 provided in the embodiment of the present invention comprises: a compressor compartment (not shown in the figure), which is arranged inside the air conditioner housing (not shown in the figure), and the two sides of the compressor 109 are respectively formed with the side plates of the air conditioner housing to form an inner area 101 and an outer area 102, wherein an indoor heat exchanger 103 is installed in the inner area 101, and an outdoor heat exchanger 104 is installed in the outer area 102; a drainage groove 105 (see Figure 3-6), formed on the bottom plate 106 of the air conditioner housing, the drainage groove 105 connects the inner area 101 and the outer area 102; a water wheel 107 is arranged between the outdoor heat exchanger 104 and the compressor compartment and extends into the drainage groove 105; a driving device 108 is arranged in the compressor compartment and the output shaft of the driving device 108 extends out of the compressor compartment and is connected to the water wheel 107; wherein, the drainage groove 105 is used to receive condensed water and drain the condensed water to the position of the water wheel 107, and the driving device 108 drives the water wheel 107 to splash the condensed water in the drainage groove 105 onto the surface of the outdoor heat exchanger 104.

[0031] In the present solution, the indoor heat exchanger 103 and the outdoor heat exchanger 104 are respectively arranged in the inner area 101 and the outer area 102; the inner area 101 and the outer area 102 are connected by the drainage groove 105 formed on the bottom plate 106 of the air conditioner shell. When the indoor heat exchanger 103 is in the cooling mode, the generated condensed water falls into the drainage groove 105, and the drainage groove 105 drains the condensed water to the position of the water wheel 107. The water wheel 107 extends into the drainage groove 105. Under the driving action of the driving device 108, the water wheel 107 splashes the condensed water in the drainage groove 105 onto the surface of the outdoor heat exchanger 104; on the one hand, the surface of the outdoor heat exchanger 104 can be cooled, the heat exchange capacity of the outdoor heat exchanger 104 can be increased, and the overall energy efficiency of the air conditioner shell can be improved; on the other hand, it can prevent too much condensed water from gathering and flowing out into the room.

[0032] Furthermore, the driving device 108 is arranged in the compressor compartment, and by opening a corresponding through hole in the compressor compartment, the output shaft of the driving device 108 extends out of the compressor compartment through the through hole and is connected to the water wheel 107, thereby reducing the space proportion occupied by the water wheel 107 and the driving device 108 in the length direction of the integrated air conditioner 100, making full use of the internal space of the integrated air conditioner 100, and making the internal structure of the integrated air conditioner 100 more compact.

[0033] Furthermore, the integrated air conditioner 100 further includes: a compressor 109 , and the compressor 109 is disposed in the compressor compartment; the driving device 108 and the compressor 109 are disposed in parallel in the width direction of the integrated air conditioner 100 .

[0034] In the present solution, by arranging both the compressor 109 and the driving device 108 in the compressor compartment, and the driving device 108 and the compressor 109 are arranged side by side in the width direction of the integrated air conditioner 100, that is, the driving device 108 and the compressor 109 are respectively arranged at the two ends in the width direction of the integrated air conditioner 100, the driving device 108 will not occupy more internal space in the length direction of the integrated air conditioner 100, thereby further reducing the space ratio occupied by the water wheel 107 and the driving device 108 in the length direction of the integrated air conditioner 100, making full use of the internal space of the compressor compartment, and making the internal structure of the integrated air conditioner 100 more compact.

[0035] Preferably, the outdoor heat exchanger 104 is a multi-fold heat exchanger, which includes a subcooling section 1041 close to the bottom plate 106 of the air conditioner case, and the subcooling section 1041 is inclined from bottom to top toward the compressor compartment, and the water wheel 107 is arranged in the projection area of ​​the subcooling section 1041 of the multi-fold heat exchanger on the bottom plate 106 of the air conditioner case.

[0036] In this solution, the multi-fold heat exchanger, i.e., the outdoor heat exchanger 104, is a heat exchanger structure with multiple sections connected, and the multi-fold heat exchanger can be more closely combined with the outdoor air duct 110 of the integrated air conditioner 100, so that the outdoor air duct 110 of the integrated air conditioner 100 is enclosed in the multi-fold heat exchanger, and the heat exchange between the outdoor air duct 110 and the outdoor heat exchanger 104 is better realized. The supercooling section 1041 of the multi-fold heat exchanger is the section closest to the bottom plate 106 of the air conditioner housing. The supercooling section 1041 is inclined upward from bottom to top toward the compressor compartment. On the one hand, the supercooling section 1041 can be tightly combined with the outdoor air duct 110, and on the other hand, an accommodating space is formed between the supercooling section 1041 and the bottom plate 106 of the air conditioner shell. The water wheel 107 is arranged in the accommodating space, that is, the water wheel 107 is arranged in the projection area of ​​the supercooling section 1041 of the multi-fold heat exchanger on the bottom plate 106 of the air conditioner shell, that is, the water wheel 107 does not occupy more internal space of the integrated air conditioner 100 in the length direction, thereby further reducing the space ratio occupied by the water wheel 107 and the driving device 108 in the length direction of the integrated air conditioner 100, making the internal structure of the integrated air conditioner 100 more compact, which is conducive to reducing the overall volume of the integrated air conditioner 100 and realizing miniaturization.

[0037] In addition, the high-temperature refrigerant is first cooled in the remaining sections except the supercooling section 1041, and then gathered in the supercooling section 1041. The water wheel 107 is set in the projection area of ​​the supercooling section 1041 of the multi-fold heat exchanger in the air conditioner housing bottom plate 106. The water wheel 107 rotates to splash the condensed water in the drainage groove 105 to the surface of the supercooling section 1041, and the surface of the supercooling section 1041 is concentratedly cooled, the supercooling degree is increased, and the heat exchange of the outdoor heat exchanger 104 and the energy efficiency ratio of the whole machine are improved. It is ensured that the maximum cooling force is given to the surface of the supercooling section 1041, thereby improving the overall cooling effect of the condensed water on the outdoor heat exchanger 104.

[0038] Preferably, the outdoor heat exchanger 104 is a three-fold heat exchanger. The outdoor heat exchanger 104 is a three-fold heat exchanger that is closely combined with the outdoor air duct 110 of the integrated air conditioner 100, and the outdoor air duct 110 is enclosed in the outdoor heat exchanger 104 to achieve a better heat exchange effect.

[0039] Preferably, see Figure 1 The length extension direction of the multi-fold heat exchanger subcooling section 1041 is parallel to the plane where the water wheel 107 rotates.

[0040] In this solution, the outdoor heat exchanger 104 is a horizontal heat exchanger, and its length extension direction is also the width direction of the integrated air conditioner 100. The plane where the water wheel 107 rotates is also the plane where the condensed water thrown out by the water wheel 107 is located. The length extension direction of the multi-fold heat exchanger supercooling section 1041 is arranged parallel to the plane where the water wheel 107 rotates. Compared with the arrangement in which the length extension direction of the multi-fold heat exchanger supercooling section 1041 intersects or is perpendicular to the plane where the water wheel 107 rotates, it can better ensure that the condensed water thrown out by the water wheel 107 is splashed onto the multi-fold heat exchanger supercooling section 1041 to the greatest extent, thereby achieving the best cooling effect.

[0041] Preferably, see Figure 3 The drainage groove 105 is formed on any side edge of the air conditioner housing bottom plate 106 in the length direction to connect the outer area 102 and the inner area 101.

[0042] In this embodiment, the drainage groove 105 is formed on any side edge in the length direction of the bottom plate 106 of the air conditioner shell to connect the outer area 102 and the inner area 101, and the condensed water of the indoor heat exchanger 103 in the inner area 101 is drained to the outer area 102. The water wheel 107 extends into the drainage groove 105 to splash the condensed water in the drainage groove 105 onto the surface of the outdoor heat exchanger 104.

[0043] In yet another embodiment, see Figure 4 The drainage groove 105 includes: a first drainage groove 1051, which connects the inner area 101 and the outer area 102; a second drainage groove 1052, which is formed between the compressor compartment and the outdoor heat exchanger 104 and connects the first drainage groove 1051; the water wheel 107 extends into the second drainage groove 1052.

[0044] In the present embodiment, the first drainage groove 1051 and the second drainage groove 1052 form a T-shaped drainage groove 105, and the first drainage groove 1051 connects the outer area 102 and the inner area 101, and drains the condensed water of the indoor heat exchanger 103 in the inner area 101 to the second drainage groove 1052 in the outer area 102. The second drainage groove 1052 is formed between the compressor compartment and the outdoor heat exchanger 104, and the water wheel 107 is also arranged between the compressor compartment and the outdoor heat exchanger 104 and extends into the second drainage groove 1052, so as to splash the condensed water in the second drainage groove 1052 more evenly onto the surface of the outdoor heat exchanger 104.

[0046] In the present embodiment, the two first drainage grooves 1051 and the second drainage groove 1052 form an H-shaped drainage groove 105, and the two first drainage grooves 1051 connect the outer area 102 and the inner area 101, and the two first drainage grooves 1051 are respectively arranged on both sides of the length direction of the air conditioner shell, which can receive more condensed water formed by the indoor heat exchanger 103 in the inner area 101, and drain the condensed water to the second drainage groove 1052 in the outer area 102, and the second drainage groove 1052 is formed between the compressor compartment and the outdoor heat exchanger 104; the water wheel 107 is also arranged between the compressor compartment and the outdoor heat exchanger 104, extending into the second drainage groove 1052, and splashing the condensed water in the second drainage groove 1052 more evenly onto the surface of the outdoor heat exchanger 104.

[0047] In yet another embodiment, see Figure 6The drainage groove 105 includes: two first drainage grooves 1051, both of which are connected to the inner area 101 and the outer area 102; a second drainage groove 1052, which is formed between the compressor compartment and the outdoor heat exchanger 104 and the two ends of the second drainage groove 1052 are respectively connected to the ends of the two first drainage grooves 1051 in the outer area 102; the water wheel 107 extends into the second drainage groove 1052.

[0048] In this embodiment, the two ends of the second drainage groove 1052 are connected to the two ends of the first drainage groove 1051 in the outer area 102, that is, in the length direction of the air conditioner housing, with the second drainage groove 1052 as the boundary. Figure 6 The second drainage groove 1052 is shown in the figure, that is, the second first drainage groove 1051 is set in the inner area 101. Figure 6 The left side of the second drainage groove 1052 shown in the figure, that is, the second first drainage groove 1051 is not provided in the outer area 102. During the operation of the integral air conditioner 100, only the indoor heat exchanger 103 provided in the inner area 101 will generate condensed water, so it is only necessary to provide the second first drainage groove 1051 in the inner area 101 to receive the condensed water formed by the indoor heat exchanger 103 in the inner area 101 and drain the condensed water to the second drainage groove 1052 in the outer area 102, thereby saving the cost of providing the drainage groove 105.

[0049] The second drainage groove 1052 is formed between the compressor compartment and the outdoor heat exchanger 104, and the water wheel 107 is also arranged between the compressor compartment and the outdoor heat exchanger 104, extending into the second drainage groove 1052, so as to splash the condensed water in the second drainage groove 1052 more evenly onto the surface of the outdoor heat exchanger 104.
