[0056] Combination Figures 1 to 7 As shown, Figure 2 and Figure 3 The arrow in the figure indicates the direction of air flow. The embodiment of the present disclosure provides a fresh air air conditioner indoor unit, which includes: a fresh air module 10, a fresh air pipeline, an exhaust pipeline 30 and a switching component 40. The fresh air module 10 includes a fresh air part 11 and an exhaust part 12. The fresh air module 10 is provided with an indoor air inlet 101 and an indoor air outlet 102. The indoor air inlet 101 is connected to the fresh air part 11, and the indoor air outlet 102 is connected to the exhaust part 12 and the fresh air part 11. The indoor air inlet 101 can be controlled to be opened or closed; one end of the fresh air pipeline is connected to the outside, and the other end of the fresh air pipeline is connected to the fresh air part 11. The outside air flows into the fresh air section 11 along the fresh air duct and flows out of the fresh air module 10 from the indoor air outlet 102; one end of the exhaust duct 30 is connected with the connecting point between the indoor air outlet 102 and the exhaust section 12, and the other end of the exhaust duct 30 extends to the outdoors, so that the air of the exhaust section 12 flows to the outdoors along the exhaust duct 30; the switching component 40 can be movably arranged at the indoor air outlet 102, and the indoor air outlet 102 corresponding to the exhaust section 12 can be controllably connected with the indoor air outlet 102 corresponding to the fresh air section 11, so that the air of the exhaust section 12 can flow out along the indoor air outlet 102 connected to the fresh air section 11.

[0057] According to the embodiment of the present disclosure, by providing an openable and closable indoor air inlet 101 in the fresh air module 10, when the indoor air inlet 101 is opened, the indoor air can flow into the fresh air unit 11 driven by the fresh air unit 11 and flow out of the fresh air module 10 from the indoor air outlet 102, so as to accelerate the circulation of the indoor air and improve the indoor temperature uniformity. Specifically, when the indoor unit of the air conditioner is in the internal circulation mode, the indoor air inlet 101 is opened, and when the indoor unit of the air conditioner is in the fresh air mode, the indoor air inlet 101 is closed.

[0058] By providing a fresh air unit 11 and a fresh air pipeline connected to the fresh air unit 11, outside air can flow into the fresh air module 10 driven by the fresh air unit 11 and flow out of the fresh air module 10 from the indoor air outlet 102, thereby providing fresh air for the room. By providing an exhaust unit 12 and an exhaust pipeline 30 connected to the indoor air outlet 102 corresponding to the exhaust unit 12, the exhaust unit 12 can drive indoor air to flow into the exhaust unit 12 and flow to the outside along the exhaust pipeline 30, so that the indoor stale air is discharged to the outside, thereby avoiding the situation where the indoor positive pressure is too large due to the increase of indoor fresh air and the reduction of the fresh air efficiency.

[0059] By setting the switching component 40, the switching component 40 can connect the exhaust part 12 with the fresh air part 11, change the air outlet direction of the exhaust part 12, and when the air conditioner indoor unit performs internal circulation, the air of the exhaust part 12 can flow out along the indoor air outlet 102 connected to the fresh air part 11, increase the air volume participating in the internal circulation, and improve the efficiency and air volume of the internal circulation. When the air conditioner indoor unit is in the fresh air mode, the switching component 40 separates the indoor air outlet 102 corresponding to the exhaust part 12 from the indoor air outlet 102 corresponding to the fresh air part 11, so that the air flowing out of the exhaust part 12 from the indoor air outlet 102 is discharged to the outside along the exhaust duct 30, and the air flowing out of the fresh air part 11 from the indoor air outlet 102 flows to the indoor.

[0060] Optionally, the switching component 40 includes: a baffle 41, which is rotatably disposed at the indoor air outlet 102, and the baffle 41 is located between the exhaust section 12 and the fresh air section 11, and is used to connect or disconnect the indoor air outlet 102 corresponding to the exhaust section 12 with the indoor air outlet 102 corresponding to the fresh air section 11; wherein the baffle 41 has a first position and a second position, and the baffle 41 can be controlled to rotate between the first position and the second position, when the baffle 41 is located at the first position, the indoor air outlet 102 corresponding to the exhaust section 12 and the indoor air outlet 102 corresponding to the fresh air section 11 are independent of each other, and when the baffle 41 is located at the second position, the indoor air outlet 102 corresponding to the exhaust section 12 of the baffle 41 is connected with the indoor air outlet 102 corresponding to the fresh air section 11 and the indoor air outlet 102 corresponding to the exhaust section 12 is blocked, so that the air of the exhaust section 12 flows out along the indoor air outlet 102 corresponding to the fresh air section 11.

[0061] According to the embodiment of the present disclosure, by setting the baffle 41 and rotatably setting the baffle 41, the baffle 41 can accurately control the connection state between the exhaust part 12 and the indoor air outlet 102 corresponding to the fresh air part 11. When the baffle 41 is in the first position, the exhaust part 12 and the fresh air part 11 operate independently, the exhaust air is directly discharged to the outside through the exhaust duct 30, and the fresh air enters from the fresh air part 11 and is sent to the room through the indoor air outlet 102, so as to realize the effective exchange of the air inside and outside. When the baffle 41 is in the second position, the air of the exhaust part 12 is guided to the air outlet of the fresh air part 11, so as to realize the increase of the air volume of the internal circulation. And when the baffle 41 is in the second position, not only the air of the exhaust part 12 is guided to the indoor air outlet 102 corresponding to the fresh air part 11, but also the indoor air outlet 102 corresponding to the exhaust part 12 itself is blocked, which ensures that the air of the exhaust part 12 is fully involved in the internal circulation, rather than being directly discharged to the outside, thereby maximizing the internal circulation efficiency.

[0062] Optionally, the switching assembly 40 further includes a motor, which is drivingly connected to the baffle 41 and is used to drive the baffle 41 to rotate between the first position and the second position.

[0063] In this way, the rotation of the baffle 41 can be automatically controlled by a motor, and the user can easily switch modes through a remote control or a smart device without manual operation, thereby improving convenience.

[0064] Optionally, the fresh air portion 11 and the exhaust portion 12 are arranged side by side, and the exhaust portion 12 and the fresh air portion 11 are independent of each other, the fresh air portion 11 includes a fresh air volute 111 and a fresh air impeller 112, the fresh air impeller 112 is rotatably disposed in the fresh air volute 111, the exhaust portion 12 includes an exhaust volute 121 and an exhaust impeller 122, the exhaust impeller 122 is rotatably disposed in the exhaust volute 121; the fresh air module 10 also includes: a driving motor 13, the driving motor 13 is arranged between the exhaust portion 12 and the fresh air portion 11, and the driving motor 13 is driven and connected to both the exhaust impeller 122 and the fresh air impeller 112, for driving the exhaust impeller 122 and the fresh air impeller 112 to rotate synchronously.

[0065] By adopting the embodiment of the present disclosure, the fresh air section 11 and the exhaust section 12 are independently arranged, and both the fresh air section 11 and the exhaust section 12 have a complete fresh air volute 111 and fresh air impeller 112, an exhaust volute 121 and an exhaust impeller 122 structure, ensuring that the fresh air introduction and the indoor turbid air discharge process will not interfere with each other, and the fresh air section 11 and the exhaust section 12 can respectively and efficiently complete their respective functional tasks. By setting a drive motor 13 and driving the drive motor 13 with the exhaust impeller 122 and the fresh air impeller 112, the drive motor 13 can simultaneously drive the fresh air impeller 112 and the exhaust impeller 122 to rotate, realizing the coordinated action of fresh air intake and indoor air extraction. Two impellers can be driven to work by one motor, avoiding the waste of resources of configuring two sets of power systems separately, improving energy utilization, and ensuring the synchronization of fresh air and exhaust, which is conducive to improving the operating efficiency of the entire fresh air air conditioner indoor unit. By arranging the fresh air unit 11 and the exhaust unit 12 side by side, and the fresh air unit 11 and the exhaust unit 12 share an indoor air outlet 102, it is beneficial for the outside fresh air to exchange heat with the indoor stale air. In addition, the fresh air unit 11 and the exhaust unit 12 are arranged side by side, making the structure of the whole fresh air module 10 more compact, saving the space of the indoor unit.

[0066] Optionally, the thickness of the exhaust impeller 122 is less than or equal to half of the thickness of the fresh air impeller 112 .

[0067] By adopting the embodiment of the present disclosure, by setting the thickness of the exhaust impeller 122 to be less than or equal to half of the thickness of the fresh air impeller 112, on the one hand, the overall volume of the exhaust part 12 can be reduced, thereby reducing the thickness and occupied space of the fresh air module 10; on the other hand, it helps to balance the air volume of exhaust air and fresh air, ensuring that the two can maintain a relatively stable air volume ratio during operation, and avoiding the situation where the exhaust air volume is greater than the fresh air volume, causing negative pressure in the room.

[0068] Optionally, the fresh air air conditioner indoor unit also includes: an air outlet duct 50, one end of the air outlet duct 50 is connected to the indoor air outlet 102 corresponding to the fresh air part 11, and the other end of the air outlet duct 50 is extended laterally, and the air outlet duct 50 is provided with multiple openings, and the multiple openings are arranged at intervals along the horizontal direction.

[0069] According to the disclosed embodiment, by setting an air outlet duct 50 and connecting the air outlet duct 50 with the indoor air outlet 102 corresponding to the fresh air unit 11, the air of the fresh air unit 11 can be made to flow out along the air outlet duct 50. By setting a plurality of openings in the air outlet duct 50, and the plurality of openings are arranged at intervals along the extension direction of the air outlet duct 50, the fresh air delivered by the air conditioner can cover a wider area, effectively improving the uniformity and coverage of indoor air circulation, avoiding the phenomenon of local uneven cooling and heating, and improving indoor comfort. Users can feel a softer and more uniform flow of fresh air, avoiding the phenomenon of local overcooling or overheating that may be caused by a single air outlet. The wind speed and noise of the air outlet from a single air outlet can also be reduced to a certain extent, making the air conditioner run more quietly and creating a comfortable indoor environment.

[0070] Optionally, the air conditioner indoor unit also includes: a casing 60 and an air outlet arm 61, the fresh air module 10 is connected to the casing 60; the air outlet arm 61 is arranged below the casing 60, and the air outlet arm 61 is extended horizontally, and both ends of the air outlet arm 61 are connected to the casing 60; wherein, the air outlet duct 50 is located in the air outlet arm 61, and the air outlet arm 61 is provided with a plurality of air supply outlets 611, and the plurality of air supply outlets 611 are the same in number as the plurality of openings and are arranged one-to-one.

[0071] With the disclosed embodiment, the housing 60 is used as the main frame of the air conditioner indoor unit, providing a solid support structure, ensuring the stable installation and operation of the fresh air module 10, the air outlet arm 61 and other components. By extending the air outlet arm 61 in the horizontal direction and arranging it below the housing 60, the space at the bottom of the air conditioner indoor unit is fully utilized, which neither occupies the upper space of the room nor affects the normal activities and layout in the room. At the same time, it is convenient to hide the air outlet duct 50, making the interior decoration more neat and beautiful. By arranging the air outlet duct 50 in the air outlet arm 61, the air outlet arm 61 can block the air outlet duct 50, and the air outlet arm 61 is coordinated with the overall style of the housing 60, which improves the aesthetics of the air conditioner indoor unit. By connecting the air outlet arm 61 to the housing 60 and extending it in the horizontal direction, the stability and firmness of the overall structure are further enhanced. By setting multiple air supply outlets 611 on the air outlet arm 61 and the multiple air supply outlets 611 are the same in number as the multiple openings and are set one-to-one, fresh air can flow out through the air supply outlets 611 directly and efficiently, avoiding air volume loss and flow confusion, thereby improving the air supply effect and indoor air quality.

[0072] Optionally, an air guide 51 is provided in the air outlet duct 50 , and the air guide 51 is extended in a direction toward the opening.

[0073] According to the embodiment of the present disclosure, by setting the air guide 51 in the air outlet duct 50 and extending the air guide 51 in the direction toward the opening, the air guide 51 can effectively guide the direction of the airflow, ensuring that the fresh air or the cold or warm airflow is sent out from the opening according to a predetermined trajectory, thereby reducing the turbulence and collision of the airflow inside the duct, reducing kinetic energy loss, and thus improving the air supply efficiency of the air conditioning system. In addition, the orderly airflow helps to reduce the vortex noise generated when the air conditioner is discharged, and the air guide 51 can reduce the noise and vibration generated when the air flows.

[0074] Optionally, there are multiple air guide members 51 , and the multiple air guide members 51 are arranged at one end of the air outlet duct 50 away from the fresh air module 10 .

[0075] When the fresh air module 10 is working, if there is no appropriate air guiding measure, the fresh air may tend to flow out from the end of the air outlet duct 50, resulting in insufficient air supply at the front end and excessive air supply at the rear end. By setting a plurality of air guides 51 at the end of the air outlet duct 50 away from the fresh air module 10, this end effect can be effectively prevented, and the fresh air can be more effectively dispersed to each opening, avoiding the problem that all air volume is concentrated at the opening away from the fresh air module 10, resulting in insufficient air volume at other openings, thereby making the air volume distribution in each area of ​​the room more balanced.

[0076] Optionally, along the flow direction of the fresh air in the air outlet duct 50 , the extension dimensions of the plurality of air guides 51 toward the opening gradually increase.

[0077] According to the disclosed embodiment, by gradually increasing the extension size of the plurality of air guides 51 toward the openings along the air flow direction, the increase in the extension size of the air guides 51 means that the resistance to the air is also increased accordingly, which helps to form a certain pressure gradient in the air outlet duct 50. In this way, as the airflow flows in the air outlet duct 50, the air guides 51 can gradually increase the air volume output, so that the fresh air output at each opening is more balanced, avoiding the phenomenon of excessive air volume at the front opening and insufficient air volume at the rear opening, making the air supply of the air conditioner more uniform and improving the indoor air circulation efficiency. In addition, the gradient setting of the air guides 51 can also slow down the wind speed and reduce the impact of the airflow, thereby effectively suppressing the generation of noise.

[0078] Specifically, the number of the air guides 51 is less than the number of the openings, and the air guides 51 are arranged in a one-to-one correspondence with the openings.

[0079] Optionally, the fresh air air conditioner indoor unit further includes: a cover plate, which is movably disposed at the indoor air inlet 101 , and is used to open or close the indoor air inlet 101 .

[0080] According to the embodiment of the present disclosure, by providing a cover plate and movably arranging the cover plate at the indoor air inlet 101, the cover plate can open or close the indoor air inlet 101 at any time, so that the user can flexibly adjust the amount of fresh air introduced according to actual needs, such as opening the cover plate to introduce more fresh air when the air quality is good, and closing the cover plate when the pollution is serious to prevent pollutants from entering the room. Secondly, when the cover plate is in the closed state, it can effectively prevent dust, insects or other foreign matter from entering the interior of the air conditioner indoor unit through the indoor air inlet 101. This helps to keep the indoor unit clean and hygienic and reduce the frequency of maintenance and cleaning. Secondly, when the air conditioner indoor unit is in the fresh air mode, the user can open the cover plate, and the fresh air unit 11 can introduce part of the indoor air to mix with the fresh air, improve the temperature of the fresh air, and avoid the situation where the fresh air temperature is too high or too low, which affects the user experience.

[0081] Optionally, the fresh air air conditioner indoor unit further includes: a driving device, which is disposed on the fresh air module 10 and is drivingly connected to the cover plate, and is used to drive the cover plate to slide relative to the indoor air inlet 101.

[0082] In this way, the drive device makes the operation of the cover plate simpler and more convenient.
