[0051] In the description of the utility model, it is understood that the orientation words such as "front, back, top, bottom, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or positional relationship usually based on the orientation or positional relationship shown in the drawing, just for the convenience of describing the utility model and simplifying the description, in the absence of the opposite statement, these orientation words do not indicate and imply that the device or element indicated must have a particular orientation or be constructed and operated in a particular orientation, therefore it can not be understood as the limitation of the protection scope of the utility model;The orientation words "inner, outer" refer to the inner and outer of the contour of each component itself.

[0052] For the convenience of description, spatial relative terms can be used here, such as "on", "above", "upper surface", "upper", etc., to describe the spatial position relationship of one device or feature with other devices or features as shown in the drawing. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation of the device described in the drawing. For example, if the device in the drawing is inverted, the device described as "above" or "on" other devices or structures will be positioned "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below" orientations. The device can also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative description used here is interpreted accordingly.

[0053] In addition, it should be noted that the use of "first", "second" and the like to limit parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, and therefore can not be understood as limiting the protection scope of the utility model.

[0054] Referring to Figures 1 to 7 As shown, according to the embodiment of the utility model, a kind of integrated air conditioner is provided, for example, wall-through air conditioner, window type air conditioner or even mobile air conditioner, etc., the integrated air conditioner includes shell (not marked in the drawing and only shows part structure), the shell includes air conditioner chassis 1 at its bottom side, it can be understood that the shell also has new air device 2 assembled on the air conditioner chassis 1, compressor 42, outdoor heat exchanger 41 (including outdoor fan), indoor heat exchanger 33 and indoor fan 32 are all assembled in the shell, it can be understood that, water collecting groove (not shown in the drawing, for marking) is formed on the top surface of the air conditioner chassis 1, to be able to collect the condensate water generated by the aforementioned outdoor heat exchanger 41 and indoor heat exchanger 33 during air conditioner operation, the new air device 2 includes the outdoor side of the integrated air conditioner (such as Figure 1The fresh air inlet 201 is connected with a fresh air outlet 202 at the indoor side of the integrated air conditioner (as shown in the figure) Figure 1 The fresh air inlet 201 is connected with a fresh air outlet 202 at the indoor side of the integrated air conditioner (as shown in the figure) Figure 5 As shown in the figure, the fresh air heat exchanger 21 has a first fin group 211 in heat exchange contact with the condensed water accumulated on the air conditioner chassis 1 and a second fin group 212 in heat exchange contact with the fresh air flowing into the fresh air inlet 201. It can be understood that the fins in the second fin group 212 are parallel to each other to form a fresh air flow channel between them, and the fresh air heat exchanger 21 is made of a heat-conducting material, which can be a metal material with high thermal conductivity, such as copper or aluminum.

[0055] In this technical solution, by arranging the fresh air heat exchanger 21 with the first fin group 211 and the second fin group 212 at the fresh air inlet 201 of the fresh air device 2, the first fin group 211 can absorb the cold energy of the condensed water due to the heat exchange contact, and the cold energy absorbed by the first fin group 211 can be efficiently conducted to the second fin group 212 due to the heat-conducting material of the fresh air heat exchanger 21. Then, through the heat exchange contact between the second fin group 212 and the fresh air flow, the pre-cooling of the fresh air introduced by the fresh air device 2 is realized, that is, the cooling of the introduced fresh air by the cold energy of the condensed water is realized, without using the refrigerant in the air conditioner for cooling, and without configuring corresponding pipelines and valve components (such as electronic expansion valves and electromagnetic on-off valves) for the cooling of the fresh air in the air conditioner. In this way, the product design cost is reduced, the structure design of the air conditioner is simplified, the performance of the refrigerant circulation system of the air conditioner is not affected, and the user's use comfort is improved.

[0056] In addition, it is worth noting that the fresh air heat exchanger 21 in this application can be integrally formed by a heat-conducting material, which has smaller air flow resistance compared with the traditional heat exchanger with a tube-fin structure, because there is no heat exchange pipe in the fresh air flow channel formed by the fins, so that the fresh air flow resistance is smaller, and under the premise of the same fresh air driving force, the fresh air introduction amount can be larger.

[0057] In some embodiments, the fresh air heat exchanger 21 further includes a heat exchange base plate 213, and the first fin group 211 and the second fin group 212 are respectively arranged on opposite sides of the heat exchange base plate 213. In a specific application condition, the first fin group 211 is arranged on the lower side of the heat exchange base plate 213, and the second fin group 212 is arranged on the upper side of the heat exchange base plate 213. The planar area of the heat exchange base plate 213 is larger than the arrangement area of the first fin group 211 and the second fin group 212. Corresponding connecting holes are arranged around the outer edges of the heat exchange base plate 213, and the fresh air heat exchanger 21 is reliably fixed and connected with the air conditioner chassis 1 by screwing corresponding screws into the connecting holes.

[0058] In the technical solution, the heat exchange substrate 213 serves as the carrier of the first fin group 211 and the second fin group 212 and also serves as the connecting and fixing component of the entire fresh air heat exchanger 21, thus being simple in structure.

Thus, the whole fresh air device 2 can be effectively prevented from being arranged on the outdoor side to adversely affect the air inlet area of the outdoor heat exchanger 41, that is, the air inlet amount of the outdoor heat exchanger 41 can be ensured, thereby ensuring the use performance of the air conditioner.

When fresh air is not needed to be introduced, the fresh air damper 221 can be controlled to be closed, thereby preventing the airflow of the external environment from entering the indoor side through the fresh air inlet 201 and then entering the indoor space, causing unexpected temperature fluctuations on the indoor side or causing pollution of indoor air when the air quality of the outdoor environment is low.

[0063] The opening and closing of the aforementioned fresh air door 221 can be realized by setting a corresponding driving motor, but in this way, on the one hand, the cost is relatively high, and on the other hand, a larger installation space is required, therefore, as a more preferred implementation manner, one side of the fresh air door 221 is pivotally connected with the heat exchange air cover 22, a damper wire 222 is connected on the fresh air door 221, and the free end of the damper wire 222 is arranged on the indoor side, it can be understood that a control handle is connected on the free end of the aforementioned damper wire 222, when the user adjusts the handle, the hard and bendable damper wire (steel wire) can be displaced on its installation path, thereby driving the aforementioned fresh air door 221 to rotate around the pivot shaft between the fresh air door 221 and the heat exchange air cover 22, and then realizing the opening or closing of the fresh air door 221.

[0064] In the technical solution, the opening and closing of the fresh air door 221 is controlled by setting the damper wire 222, which can significantly reduce the space occupied by the opening and closing structure of the fresh air door 221 on the air conditioner, and the production cost is low.

[0067] In some embodiments, a filter 223 is further arranged at the fresh air inlet 201, the filter 223 is between the fresh air door 221 and the fresh air heat exchanger 21, and is assembled on the heat exchange air cover 22.

[0068] In the technical solution, the filter 223 is arranged between the fresh air door 221 and the fresh air heat exchanger 21, which can filter and clean the introduced fresh air, the filter 223 can be a filter screen, and of course, other types of filters can also be used according to specific requirements, such as HEPA filter modules.

[0069] It can be understood that in order to form a driving force for introducing fresh air, the fresh air duct 23 is provided with a fresh air fan 24, and in some embodiments, the fresh air fan 24 is a cross-flow fan.

[0070] In the technical solution, the fresh air fan 24 adopts a cross-flow fan, which can significantly improve the amount of fresh air introduction.

[0071] As shown in Figure 6 and Figure 7 shown, the cross-flow fan includes a fan blade 241, one axial end of the fan blade 241 is provided with a fan blade shaft sleeve 245 which forms a rotating support for the axial end of the fan blade 241, and the other axial end of the fan blade 241 is provided with a fresh air motor 242 which drives the rotation thereof, the outer side of the aforementioned fresh air motor 242 is provided with a motor protective cover (not marked in the figure), the motor protective cover is formed by the buckling of a motor cover shell 243 and a cover shell end cover 244, and the aforementioned fresh air duct 23 specifically includes a fresh air volute 231 and a fresh air volute tongue 232 which are spliced to form a whole.
