[0030] Figure 1 The schematic structural diagram of the air conditioner indoor unit 100 is shown in FIG. Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides an air conditioner indoor unit 100. The air conditioner indoor unit 100 includes a housing 110 and a fresh air outlet structure 120. The housing 110 is formed with a heat exchange air duct 130, and the heat exchange air duct 130 has an air inlet 131 and an air outlet 132 that are connected to the indoor environment. The fresh air outlet structure 120 includes a fresh air channel 122 and a fresh air outlet 121, and the fresh air channel 122 is formed with a fresh air outlet 121, and the fresh air outlet 121 is located in the heat exchange air duct 130, and the fresh air channel 122 is connected with the heat exchange air duct 130 through the fresh air outlet 121, and is used to transport the fresh air in the fresh air channel 122 to the heat exchange air duct 130, and the fresh air outlet 121 is in a long strip shape. In other words, the fresh air outlet structure 120 is in a long strip shape.

[0031] Specifically, Figure 2 and Figure 3 As shown, the air inlet 131 and the air outlet 132 are formed in the housing 110. The fresh air passage 122 is located in the housing 110. Figure 4As shown, an indoor heat exchanger 140 is provided in the heat exchange air duct 130. Indoor air can enter the heat exchange air duct 130 through the air inlet 131, and form heat exchange air after heat exchange in the indoor heat exchanger 140, and the heat exchange air is transported to the room through the air outlet 132. The heat exchange air duct 130 has an air inlet section and an air outlet section, wherein the channel section between the air inlet 131 and the indoor heat exchanger 140 is the air inlet section, and the channel section between the indoor heat exchanger 140 and the air outlet 132 is the air outlet section. The fresh air outlet 121 can be set at the air inlet section of the heat exchange air duct 130, and can also be set at the air outlet section of the heat exchange air duct 130.

[0032] When the indoor heat exchanger 140 is working, the working process of the air conditioner indoor unit 100 in the mixed air mode is as follows: when the fresh air outlet 121 is set at the air outlet section of the heat exchange air duct 130, the fresh air is transported to the air outlet section of the heat exchange air duct 130 through the fresh air outlet 121, mixed with the indoor air (heat exchange air) that has undergone heat exchange, to form mixed air, and the mixed air can be discharged to the room through the air outlet 132. When the fresh air outlet 121 is set at the air inlet section of the heat exchange air duct 130, the fresh air can be transported to the air inlet section of the heat exchange air duct 130 through the fresh air outlet 121, mixed with the indoor air inlet, to form mixed air, and the mixed air is heat exchanged by the indoor heat exchanger 140 to form mixed heat exchange air, and the mixed heat exchange air can be discharged to the room through the air outlet 132.

[0033] When the indoor heat exchanger 140 is not working and the air conditioner operates in a single fresh air mode, the fresh air is transported into the heat exchange air duct 130 through the fresh air outlet 121 and then discharged into the room through the air outlet 132 .

[0034] In this embodiment, on the one hand, since the fresh air outlet 121 is arranged in the heat exchange air duct 130, no additional air outlet space is required, and the overall installation space of the indoor unit can be saved. On the other hand, since the fresh air outlet 121 is in a long strip shape, the fresh air outlet 121 can have a larger fresh air outlet area, so that the fresh air outlet can be uniform. When the air conditioner operates in a single fresh air mode, the air outlet of the air conditioner can be made uniform. When the air conditioner operates in a mixed air mode, the fresh air output from the fresh air outlet 121 can be fully mixed with the indoor air before or after heat exchange in the heat exchange air duct 130, so that the air blown out by the air conditioner indoor unit 100 is more uniform and soft, and the heat exchange air can be used to increase the air supply distance of the fresh air. Therefore, this embodiment can improve the uniformity of the air outlet of the air conditioner indoor unit 100, thereby improving the uniformity of the indoor temperature, the quality of the air conditioner and the user's experience. In addition, in winter, condensation of fresh air at the outlet can be reduced.

[0035] In some optional embodiments of the present invention, the fresh air outlet 121 extends along the length direction of the housing 110. The air outlet 132 of the heat exchange air duct 130 extends along the length direction of the housing 110. In other words, the fresh air outlet structure 120 extends along the length direction of the housing 110.

[0036] In this embodiment, the fresh air outlet 121 extends along the length direction of the housing 110, which facilitates the design and assembly of the fresh air outlet structure 120. In addition, the fresh air outlet structure 120 in this embodiment can fully exchange heat and mix the fresh air with the air in the heat exchange air duct 130, which is beneficial to the uniformity of the indoor temperature.

[0037] In some optional embodiments of the utility model, the fresh air outlet 121 faces the air outlet 132 of the heat exchange air duct, and the fresh air outlet 121 and the air outlet 132 are arranged at intervals, so that the fresh air and the heat exchange air are mixed in the heat exchange air duct 130 and then discharged through the air outlet 132. In other words, the fresh air outlet 121 is arranged at the air outlet section of the heat exchange air duct 130. In this embodiment, since there is a certain distance between the fresh air outlet 121 and the air outlet 132 of the heat exchange air duct 130, it is more conducive to the full mixing and heat exchange of the fresh air and the heat exchange air, so that the temperature of the mixed air can be more uniform.

[0038] Furthermore, the air conditioner indoor unit 100 also includes an indoor fan 150 , and the fresh air outlet structure 120 is arranged between the indoor fan 150 and the air outlet 132 so that the fresh air and the heat exchange air are mixed in the heat exchange air duct 130 and then discharged through the air outlet 132 .

[0039] Furthermore, a mounting groove is provided on the duct wall of the heat exchange duct 130, and the fresh air outlet structure 120 is inserted into the mounting groove. Specifically, the fresh air outlet 121 can be flush with the inner wall surface of the heat exchange duct 130; the fresh air outlet 121 can also be located on the inner side of the inner wall surface of the heat exchange duct 130. When the fresh air outlet 121 is flush with the inner wall surface of the heat exchange duct 130, a larger air outlet space can be provided in the heat exchange duct 130.

[0040] In some optional embodiments of the utility model, a guide structure is provided in the fresh air passage 122 to make the fresh air in the fresh air passage 122 flow evenly to the fresh air outlet 121. By providing the guide structure in this embodiment, on the one hand, the fresh air can be delivered to various positions of the fresh air outlet 121, so that the fresh air outlet is more even; on the other hand, when the fresh air flows in the fresh air passage 122, it contacts the guide structure to reduce the wind speed of the fresh air, so that the fresh air can fully exchange heat with the heat exchange air, so that the air outlet of the indoor unit can be softer and more even.

[0041] like Figures 4 to 5As shown, in some optional embodiments of the utility model, the guide structure includes a plurality of guide ribs 123, and the plurality of guide ribs 123 are spaced apart along the length direction of the fresh air channel 122 to form a plurality of first channels 124 in the fresh air channel 122; a second channel 125 is formed between each guide rib 123 and the channel wall of the fresh air channel 122, and the second channel 125 is connected to the first channel 124 to transport the fresh air in the second channel 125 to the fresh air outlet 121 through each first channel 124. The guide structure of this embodiment has the advantages of being easy to manufacture and assemble.

[0042] In some optional embodiments of the present invention, the fresh air channel 122 extends along the length direction of the housing 110, and one end of the fresh air channel 122 has a fresh air inlet, which can be connected to the air outlet 161 of the fresh air module 160. The other end of the fresh air channel 122 is a closed structure, the fresh air outlet 121 is formed on the front wall of the fresh air channel 122, and the second channel 125 is located behind each guide rib 123. When in use, the fresh air enters the fresh air channel 122 from the fresh air inlet, and then flows along the second channel 125 to the other end thereof. During the flow process, the fresh air can flow to the fresh air outlet 121 through the first channel 124.

[0043] like Figure 5 As shown, in some optional embodiments of the present invention, one side of the guide rib 123 extends to the fresh air outlet 121. The other side of the guide rib 123 has a gap with the channel wall of the fresh air channel 122 away from the fresh air outlet 121 to form a second channel 125.

[0044] In some alternative embodiments, one side of the guide rib 123 does not extend to the fresh air outlet 121 , that is, there is a certain distance between the two.

[0045] Compared with the structure in which one side of the guide rib 123 does not extend to the fresh air outlet 121, the one side of the guide rib 123 extends to the fresh air outlet 121, which can further enhance the guiding effect of the guide rib 123 and make the fresh air outlet more uniform; in addition, the contact area between the guide rib 123 and the fresh air can be further enhanced, thereby further reducing the wind speed of the fresh air and allowing the fresh air and heat exchange air to be mixed more evenly.

[0046] In some optional embodiments of the utility model, the projection of the guide rib 123 in the length direction of the fresh air channel 122 is an arc. In other words, the guide rib 123 is an arc-shaped plate, which can increase the contact area between the guide rib 123 and the fresh air, which is conducive to the full mixing of the fresh air and the air in the heat exchange air duct 130; it can also reduce noise.

[0047] In some alternative embodiments, the projection of the guide rib 123 in the length direction of the fresh air passage 122 is a straight line, that is, the guide rib 123 is a plane. In other alternative embodiments, the projection of the guide rib 123 in the length direction of the fresh air passage 122 is a broken line.

[0048] In some optional embodiments of the present invention, the plane where the fresh air outlet 121 is located is an inclined plane.

[0049] In some alternative embodiments, the plane where the fresh air outlet 121 is located is a vertical plane.

[0051] In some optional embodiments of the utility model, the guide structure can also be a plurality of guide strips. The guide strip is fixed on the channel wall of the fresh air channel 122 away from the fresh air outlet 121, and the guide strip extends from the channel wall of the fresh air channel 122 to the fresh air outlet 121. The guide strip is vertically arranged or inclined to the fresh air outlet 121. There is a certain gap between any adjacent guide strips.

[0052] In some optional embodiments of the present invention, the air conditioner indoor unit 100 further includes a fresh air module 160, which is disposed on the housing 110 and is used to deliver fresh air to the fresh air passage 122. When in use, the fresh air module 160 delivers fresh air to the fresh air passage 122, and delivers fresh air to the heat exchange air duct 130 through the fresh air outlet 121 of the fresh air passage 122.

[0053] Specifically, the fresh air module 160 can be arranged at the end of the heat exchange air duct 130, and the fresh air module 160 can also be arranged at a side away from the air outlet 132 of the heat exchange air duct 130. For example, when the housing 110 is arranged horizontally, the fresh air module 160 can be arranged at the left end or the right end of the housing 110, and the fresh air module 160 can also be arranged at the rear of the housing 110. Preferably, the fresh air module 160 is arranged in the housing 110 and is located at the rear side of the heat exchange air duct 130, which does not increase the length of the whole machine and has a simpler appearance.

[0054] Furthermore, if Figure 3 and Figure 4 As shown, the fresh air module 160 is connected to a fresh air duct 162 , one end opening of the fresh air duct 162 is connected to the fresh air module 160 , and the other end opening of the fresh air duct 162 is connected to the outdoor environment to transport outdoor fresh air into the fresh air module 160 .

[0055] In some optional embodiments of the present utility model, the air conditioner indoor unit 100 is an embedded air conditioner indoor unit 100, the fresh air module 160 is located behind the heat exchange air duct 130, the air inlet 131 and the air outlet 132 of the heat exchange air duct 130 are both arranged on the front side of the housing 110, and the air inlet 131 of the heat exchange air duct 130 is located above the air outlet 132. The fresh air module 160 is located inside the housing 110. The air conditioner indoor unit 100 is embedded in the decorated cabinet.

[0056] Furthermore, the fresh air module 160 is arranged at the rear side of one end of the heat exchange air duct 130. The air outlet 161 of the fresh air module 160 is connected to the fresh air inlet of the fresh air channel 122 to transport the fresh air in the fresh air module 160 to the fresh air channel 122. The indoor heat exchanger includes a first part and a second part which are arranged in sequence in the front-to-back direction, the first part is connected to the second part, and the first part is adjacent to the air inlet relative to the second part in the front-to-back direction. The second part has a first end and a second end, and the first end is located obliquely below the second end; the first part has a third end and a fourth end, the third end is connected to the second end, and the fourth end is located obliquely below the third end, and the fourth end is lower than the first end. In this embodiment, through the above arrangement, the heat exchange area of ​​the indoor heat exchanger can be increased, so that the indoor heat exchanger has a good heat exchange effect.

[0057] like Figure 3 As shown, during operation, under the action of the indoor fan 150, the indoor air enters the heat exchange duct 130 through the air inlet 131 of the heat exchange duct 130, and forms heat exchange air after heat exchange with the indoor heat exchanger 140; at the same time, under the action of the fresh air module 160, the fresh air enters the fresh air module 160 through the fresh air pipe 162, and flows to the fresh air outlet 121 through the fresh air channel 122, and finally flows into the heat exchange duct 130. After the above-mentioned heat exchange air and fresh air are mixed in the air outlet section of the heat exchange duct 130, they flow into the room through the air outlet 132 of the heat exchange duct 130.

[0058] In some other optional embodiments, the air-conditioning indoor unit 100 may also be a wall-mounted air conditioner, etc.
