[0034] Figure 1 The schematic structural diagram of the air conditioner indoor unit 100, as shown in Figure 1 shown, and referring to Figures 2 to 7 , an embodiment of the present 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 forms a heat exchange air duct 130, and the heat exchange air duct 130 has an air inlet 131 and an air outlet 132 communicating with the indoor environment. An indoor heat exchanger 140 is provided in the heat exchange air duct. The heat exchange air duct 130 includes a first air duct section 133, and the first air duct section 133 is located between the indoor heat exchanger 140 and the air inlet 131. The fresh air outlet structure 120 includes a fresh air channel 122, and the fresh air channel 122 forms a fresh air outlet 121. The fresh air outlet 121 is located in the first air duct section 133 of the heat exchange air duct 130. The fresh air channel 122 communicates with the first air duct section 133 of the heat exchange air duct 130 through the fresh air outlet 121, and is used for delivering the fresh air in the fresh air channel 122 to the first air duct section 133 of the heat exchange air duct 130, and the fresh air outlet 121 is in a long strip shape. That is to say, the fresh air outlet structure 120 is in a long strip shape.

[0035] Specifically, as shown in Figure 1 and Figure 4 shown, the air inlet 131 and the air outlet 132 are formed on the housing 110. The fresh air channel 122 is located inside the housing 110. The heat exchange air duct 130 further includes a second air duct section 134, and the second air duct section 134 is located between the indoor heat exchanger 140 and the air outlet 132. That is to say, the first air duct section 133 is the air inlet section, and the second air duct section 134 is the air outlet section. An indoor fan 150 is also provided in the heat exchange air duct 130 for promoting the circulation of indoor air.

[0036] When the indoor heat exchanger 140 is working and the air conditioner indoor unit 100 operates in the mixed air mode, the working process is as follows: The indoor air can enter the first air duct section 133 of the heat exchange air duct 130 through the air inlet 131, and at the same time, the fresh air enters the first air duct section 133 of the heat exchange air duct 130 through the fresh air outlet 121; it is mixed with the indoor incoming air in the first air duct section 133 to form a mixed air. After the mixed air is heat-exchanged by the indoor heat exchanger 140, a mixed heat-exchanged air is formed; the mixed heat-exchanged air can be fully mixed again during the process of flowing towards the air outlet, and finally is discharged into the room through the air outlet 132.

[0037] When the indoor heat exchanger 140 is not working and the air conditioner operates in the single fresh air mode, after the fresh air is delivered into the first air duct section 133 of the heat exchange air duct 130 through the fresh air outlet 121, it is discharged into the room through the air outlet 132.

[0038] In this embodiment, on the one hand, since the fresh air outlet 121 is arranged in the first air duct section 133 of the heat exchange air duct 130, no additional fresh air outlet space is required, which can save the overall installation space of the indoor unit. On the other hand, since the fresh air outlet 121 is strip-shaped, the fresh air outlet 121 can have a relatively large fresh air outlet area, enabling the fresh air to be evenly discharged. When the air conditioner operates in the single fresh air mode, the air outlet of the air conditioner can be made uniform. When the air conditioner operates in the mixed air mode, the fresh air conveyed by the fresh air outlet 121 and the indoor air conveyed by the heat exchange air duct air inlet are heat-exchanged by the indoor heat exchanger and then form a mixed heat-exchanged air, which is discharged into the room through the air outlet, so that the air blown out by the air conditioner indoor unit 100 is more uniform and gentle, and the air supply distance of the fresh air can be increased by using the indoor fan. Therefore, this embodiment can improve the air outlet uniformity of the air conditioner indoor unit 100, thereby improving the uniformity of the indoor temperature, the quality of the air conditioner and the user experience. In addition, this embodiment can also prevent condensation of fresh air at the outlet.

[0039] As Figure 4 and Figure 5 shown, in some alternative embodiments of the present utility model, the fresh air outlet 121 faces the indoor heat exchanger 140 to blow fresh air towards the indoor heat exchanger 140. In this embodiment, the fresh air outlet 121 facing the indoor heat exchanger 140 can enable the fresh air blown out by the fresh air outlet 121 to be quickly heat-exchanged with the indoor heat exchanger 140 and can also reduce the resistance to the indoor air intake.

[0040] In some other alternative embodiments of the present utility model, the fresh air outlet 121 can also face other positions of the first air duct section 133 of the heat exchange air duct 130.

[0041] In some alternative embodiments of the present utility model, the indoor heat exchanger 140 includes a windward surface corresponding to the fresh air outlet 121, and the projection of the fresh air outlet 121 on the plane where the windward surface is located completely falls within the windward surface. That is to say, the air outlet area of the fresh air outlet is smaller than the area of the windward surface, which is beneficial for the indoor heat exchanger 140 to fully heat-exchange the fresh air, so that the air blown out by the indoor unit is softer and can further avoid condensation of fresh air at the air outlet.

[0042] In some alternative embodiments of the present utility model, 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. That is to say, the fresh air outlet structure 120 extends along the length direction of the housing 110.

[0043] In this embodiment, the fresh air outlet 121 extends along the length direction of the housing 110, facilitating the design and assembly of the fresh air outlet structure 120. In addition, the fresh air outlet structure 120 in this embodiment can enable the fresh air to fully exchange heat and mix with the air in the heat exchange air duct 130, thereby being beneficial to the uniformity of the indoor temperature.

[0044] Furthermore, an installation groove is provided on the duct wall of the first duct section 133 of the heat exchange air duct 130, and the fresh air outlet structure 120 is inserted into the installation groove. Specifically, the fresh air outlet 121 can be flush with the inner wall surface of the first duct section 133 of the heat exchange air duct 130; the fresh air outlet 121 can also be located inside the inner wall surface of the first duct section 133 of the heat exchange air duct 130. In this embodiment, by providing the installation groove, the assembly of the fresh air outlet structure 120 can be facilitated.

[0045] In some alternative embodiments of the present utility model, a flow guiding structure is provided in the fresh air passage 122 to make the fresh air in the fresh air passage 122 flow uniformly towards the first duct section 133 of the fresh air passage 122. By providing the flow guiding structure in this embodiment, on the one hand, the fresh air can be delivered to various positions of the fresh air outlet 121, making the fresh air outlet more uniform; on the other hand, when the fresh air flows in the fresh air passage 122, contacting the flow guiding structure can reduce the wind speed of the fresh air, so that the fresh air can fully exchange heat with the indoor heat exchanger, and thus the air outlet of the indoor unit can be more gentle and uniform.

[0046] As Figure 6 and Figure 7 shown, in some alternative embodiments of the present utility model, the flow guiding structure includes a plurality of flow guiding ribs 123, and the plurality of flow guiding ribs 123 are spaced apart along the length direction of the fresh air passage 122 to form a plurality of first passages 124 in the fresh air passage 122; a second passage 125 is formed between each flow guiding rib 123 and the passage wall of the fresh air passage 122, and the second passage 125 is communicated with the first passage 124 to deliver the fresh air in the second passage 125 to the first duct section 133 through each first passage 124. The flow guiding structure of this embodiment has the advantages of being easy to manufacture and assemble.

[0047] In some alternative embodiments of the present utility model, the fresh air passage 122 extends along the length direction of the housing 110, one end of the fresh air passage 122 has a fresh air inlet, and the fresh air inlet can be connected to the air outlet part 161 of the fresh air module 160. The other end of the fresh air passage 122 is a closed structure, the fresh air outlet 121 is formed on the front wall of the fresh air passage 122, and the second passage 125 is located behind each flow guiding rib 123. During use, the fresh air enters the fresh air passage 122 from the fresh air inlet, and then flows towards the other end along the second passage 125. During the flowing process, the fresh air can flow towards the fresh air outlet 121 through the first passage 124.

[0048] AsFigure 5 As shown, in some alternative embodiments of the present utility model, one side of the flow guiding rib 123 extends to the fresh air outlet 121. There is a gap between the other side of the flow guiding rib 123 and the channel wall of the fresh air channel 122 in the direction away from the fresh air outlet 121 to form a second channel 125.

[0049] In some alternative embodiments, one side of the flow guiding rib 123 does not extend to the fresh air outlet 121, that is, there is a certain distance between them.

[0050] Compared with the structure where one side of the flow guiding rib 123 does not extend to the fresh air outlet 121, when one side of the flow guiding rib 123 extends to the fresh air outlet 121, the flow guiding effect of the flow guiding rib 123 can be further improved, making the fresh air outlet more uniform; in addition, the contact area between the flow guiding rib 123 and the fresh air can be further increased, the wind speed of the fresh air can be further reduced, the heat exchange effect of the indoor heat exchanger on the fresh air can be improved, and a better air mixing effect can also be achieved.

[0051] In some alternative embodiments of the present utility model, the projection of the flow guiding rib 123 in the length direction of the fresh air channel 122 is arc-shaped. That is to say, the flow guiding rib 123 is an arc-shaped plate, which can increase the contact area between the flow guiding rib 123 and the fresh air, facilitating the full mixing of the fresh air and the air in the heat exchange air duct 130; it can also reduce noise.

[0052] In some alternative embodiments, the projection of the flow guiding rib 123 in the length direction of the fresh air channel 122 is linear, that is to say, the flow guiding rib 123 is a plane. In some other alternative embodiments, the projection of the flow guiding rib 123 in the length direction of the fresh air channel 122 is zigzag.

[0053] In some alternative embodiments of the present utility model, the plane where the fresh air outlet 121 is located is an inclined plane.

[0054] In some alternative embodiments, the plane where the fresh air outlet 121 is located is a vertical plane.

[0055] Compared with the vertical plane structure, adopting the inclined plane structure can increase the air outlet area of the fresh air outlet 121, and make the fresh air and the heat exchange air mix more evenly.

[0056] In some alternative embodiments of the present utility model, the flow guiding structure can also be multiple flow guiding strips. The flow guiding strips are fixed on the channel wall of the fresh air channel 122 on the side away from the fresh air outlet 121, and the flow guiding strips extend from the channel wall of the fresh air channel 122 to the fresh air outlet 121. The flow guiding strips are perpendicular or inclined to the fresh air outlet 121. There is a certain gap between any adjacent flow guiding strips.

[0057] In some alternative embodiments of the present utility model, the air conditioner indoor unit 100 further includes a fresh air module 160. The fresh air module 160 is disposed on the housing 110 and is configured to deliver fresh air to the fresh air passage 122. During use, the fresh air module 160 delivers fresh air to the fresh air passage 122 and conveys it into the heat exchange air duct 130 through the fresh air outlet 121 of the fresh air passage 122.

[0058] Specifically, the fresh air module 160 can be disposed at the end of the heat exchange air duct 130, and the fresh air module 160 can also be disposed on a side away from the air outlet 132 of the heat exchange air duct 130. For example, when the housing 110 is horizontally arranged, the fresh air module 160 can be disposed at the left end or the right end of the housing 110, and the fresh air module 160 can also be disposed at the rear of the housing 110. Preferably, the fresh air module 160 is disposed inside the housing 110 and is located at the rear side of the heat exchange air duct 130, without increasing the overall length of the machine and presenting a more concise appearance.

[0059] In some alternative embodiments of the present utility model, the air outlet portion 161 of the fresh air module 160 is connected to the fresh air inlet of the fresh air passage 122 to convey the fresh air inside the fresh air module 160 into the fresh air passage 122.

[0060] Furthermore, as Figure 4 and Figure 5 shown, the fresh air module 160 is connected with a fresh air pipe 162. One end opening of the fresh air pipe 162 is communicated with the fresh air module 160, and the other end opening of the fresh air pipe 162 is communicated with the outdoor environment to convey outdoor fresh air into the fresh air module 160.

[0061] As Figure 4 and Figure 5 shown, in some alternative embodiments of the present utility model, the indoor heat exchanger includes a first part 141 and a second part 142 arranged in sequence in the front-rear direction. The first part 141 is connected to the second part 142. The first part 141 is adjacent to the air inlet in the front-rear direction relative to the second part 142. The fresh air outlet 121 faces the second part 142 to blow the fresh air towards the second part 142. In this embodiment, through the above arrangement, the heat exchange area of the indoor heat exchanger can be increased, enabling the indoor heat exchanger to have a good heat exchange effect.

[0062] Even further, the second part 142 has a first end and a second end, and the first end is located diagonally below the second end; the first part 141 has a third end and a fourth end, the third end is connected to the second end, the fourth end is located diagonally below the first end, and the fourth end is lower than the first end. The fresh air module is located behind the second part 142 of the heat exchanger, that is to say, the fresh air module is located at the upper position at the rear side of the heat exchange air duct 130. Through the above arrangement, it is convenient for the connection and assembly of the fresh air module and the fresh air outlet structure 120.

[0063] In some alternative 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 at the upper rear of the housing 110. The air conditioner indoor unit 100 is embedded in the decorated cabinet. The heat exchange air duct 130 adopted in this embodiment adopts a structure of forward air intake and forward air outlet, without being restricted by the cabinet.

[0064] 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 part 161 of the fresh air module 160 is connected to the fresh air inlet of the fresh air duct 122 to deliver the fresh air in the fresh air module 160 into the fresh air duct 122.

[0065] As Figure 4 shown, during the working process, under the action of the indoor fan 150, the indoor air enters the first air duct section 133 of the heat exchange air duct 130 through the air inlet 131 of the heat exchange air duct 130. 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, flows through the fresh air duct 122 to the fresh air outlet 121, and finally flows into the first air duct section 133 of the heat exchange air duct 130. The above-mentioned fresh air and indoor air are heat-exchanged by the indoor heat exchanger to form mixed air, and flow into the room through the air outlet 132 of the heat exchange air duct 130.

[0066] In some other alternative embodiments, the air conditioner indoor unit 100 can also be a wall-mounted air conditioner or the like.

[0067] This embodiment also provides an air conditioner, which includes the air conditioner indoor unit 100 described in any one of the above.

[0068] So far, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, still, without departing from the spirit and scope of the present utility model, many other variations or modifications that conform to the principles of the present utility model can be directly determined or derived based on the content disclosed in the present utility model.
