[0056] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other.

[0057] The indoor air conditioner provided in this embodiment can be a floor-standing air conditioner. When the indoor air conditioner is cooling or heating, the flow guide device is used to disturb the blown air flow, and a "pear-shaped" air flow swirl is formed near the indoor air conditioner, expanding the radiation range of the air flow, which not only helps to improve the indoor heating or cooling efficiency, but also helps to make the indoor temperature uniform.

[0058] Combined Figures 1 to 17 As shown in the figure, the embodiments of the present disclosure provide an indoor air conditioner, including: a housing 10, a front panel 20, and a flow guide device.

[0059] The housing 10 defines a heat exchange air duct 101; a cross-flow fan 90 is provided in the heat exchange air duct 101. Herein, the dual cross-flow fan 90 is taken as an example for display in this embodiment. The front panel 20 is connected to the housing 10 and faces the user. A display screen may be provided on the front panel 20 to display temperature, the operation mode of the air conditioner, etc. A main air outlet and a fresh air outlet 202 are formed on the front panel 20; the main air outlet is communicated with the heat exchange air duct 101, and the cross-flow fan 90 blows the air flow in the heat exchange air duct 101 through the main air outlet to cool or heat the indoor environment. The flow guide device includes a flow guide fan 601, and the flow guide fan 601 is provided on the front panel 20 and is communicated with the fresh air outlet 202; wherein, the air duct where the flow guide device is located is independently arranged from the heat exchange air duct 101. When the main air outlet is discharging air, the air flow generated by the flow guide fan 601 is blown out from the fresh air outlet 202 to disturb the flow direction of the air flow discharged from the main air outlet.

[0060] The air duct where the flow guide device is located is independently arranged from the heat exchange air duct 101. In this way, the air flow passing through the flow guide fan 601 and the air flow passing through the cross-flow fan 90 do not affect each other. The flow guide fan 601 blows the air flow out from the fresh air outlet 202, and the cross-flow fan 90 blows the air flow out from the main air outlet.

[0061] When the flow guide fan 601 and the cross-flow fan 90 are turned on simultaneously, a "pear-shaped" air flow vortex is formed around the indoor air conditioner, expanding the influence range of the air flow. Compared with only turning on the cross-flow fan 90, due to the flow guide effect of the flow guide fan 601, the air flow rate and velocity in the indoor corner are increased, multiple air flow vortices are formed indoors, and the air flow vortices in the indoor corner are complete and smooth.

[0062] In addition, the spoiler fan 601 also increases the disturbing force of the indoor air flow, accelerating the air flow to return to the main air inlet 103 of the air conditioner, which is beneficial to the uniform indoor environmental temperature. In practical applications, after the air flow blown out from the spoiler fan 601 reaches a certain position in the room, it decelerates under the action of the return flow blown out by the cross-flow fan 90 of the air conditioner and then returns to the main air outlet of the air conditioner, where it mixes with the air flow blown out from the main air outlet and participates in the indoor air circulation again.

[0063] When using the indoor unit of the air conditioner provided by the embodiment of the present disclosure, when the spoiler fan 601 and the cross-flow fan 90 are turned on simultaneously, the air flow blown out by the spoiler fan 601 disturbs the air flow flowing out from the main air outlet, forming a "pear-shaped" air flow swirl near the indoor unit of the air conditioner, which not only expands the radiation range of the air flow, but also helps to improve the uniformity of the indoor temperature.

[0064] Optionally, the main air outlet includes a symmetrically arranged first air outlet 2011 and a second air outlet 2012, both of which are communicated with the heat exchange air duct 101; wherein, the fresh air outlet 202 is located between the first air outlet 2011 and the second air outlet 2012.

[0065] The first air outlet 2011 and the second air outlet 2012 are respectively located on both sides of the front panel 20 and on both sides of the fresh air outlet 202. In this way, when the fresh air outlet 202 discharges air, it can affect the air flow discharged from the first air outlet 2011 and the second air outlet 2012 at the same time, so as to further improve the disturbing effect.

[0066] The first air outlet 2011 and the second air outlet 2012 are arranged close to the edge of the air conditioner. The air flow discharged from the first air outlet 2011 and the second air outlet 2012 flows around and then returns to the air inlet of the air duct where the spoiler fan 601 is located.

[0067] In addition, when the spoiler fan 601 is turned on, for the space area directly opposite to the front panel 20, the spoiler fan 601 can directly supply air through the fresh air outlet 202, which can not only avoid the discomfort caused by the direct blowing of the first air outlet 2011 and the second air outlet 2012, but also reduce the air flow turbulence degree in the directly opposite space area, increase the air flow fluidity, and make the indoor temperature distribution more uniform. In addition, it can also undertake part of the cooling function, reduce the energy consumption of the cross-flow fan 90, and achieve energy conservation and emission reduction.

[0068] The distance from the fresh air outlet 202 to the first air outlet 2011 is equal to the distance from the fresh air outlet 202 to the second air outlet 2012. In this way, it can ensure the uniformity of the air flow disturbance of the first air outlet 2011 and the second air outlet 2012, so as to ensure the uniform overall force of the indoor unit of the air conditioner.

[0069] Optionally, the air conditioner indoor unit further includes: a partition 30 disposed inside the housing 10, and separating the accommodation cavity inside the housing 10 into an independent heat exchange air duct 101 and a fresh air duct; the shape of the partition 30 matches the installation position and shape of the cross-flow fan 90 to ensure that the enclosed heat exchange air duct 101 meets the requirements; wherein, the fresh air duct is communicated with the fresh air outlet 202, and the flow disturbance device is located inside the fresh air duct.

[0070] The fresh air duct is between the partition 30 and the front panel 20. The heat exchange air duct 101 and the fresh air duct are arranged at intervals through the partition 30 to prevent the mixing of the air flow in the heat exchange air duct 101 and the fresh air duct, thereby affecting the temperature, flow rate and velocity of the air flow at the main air outlet and the fresh air outlet 202.

[0071] The flow disturbance device is located inside the fresh air duct and is used to blow the air inside the fresh air duct out from the fresh air outlet 202 to disturb the flow direction of the air flow blown out from the main air outlet.

[0072] Optionally, the flow disturbance device further includes: a plurality of air guiding members 602 disposed at the fresh air outlet 202 to guide the flow direction of the air flow generated by the flow disturbance fan 601.

[0073] In this embodiment, a plurality of air guiding members 602 are disposed at the fresh air outlet 202. In this way, the air flow blown out from the fresh air outlet 202 is guided, so as to guide the flow direction of the air flow blown out by the flow disturbance fan 601. The air guiding member 602 can be understood as an air guiding grille.

[0074] Optionally, the air guiding members 602 are arranged in a circumferential and radial manner around the fresh air outlet 202. In this way, under the guidance of the air guiding members 602, the air flow at the fresh air outlet 202 is blown out in a spiral shape.

[0075] Optionally, a display screen is provided at the fresh air outlet 202, and the air guiding members 602 are arranged in a circumferential and radial manner around the display screen. Preferably, the plurality of air guiding members 602 are arranged in a spiral direction. As shown in combination with Figure 6 shown.

[0076] Optionally, the flow disturbance device further includes: an air duct switching device disposed inside the fresh air duct for controlling the on-off of the air path in the fresh air duct. The on-off of the air path in the fresh air duct can be controlled through the air duct switching device, so as to control the air volume at the fresh air outlet 202 to meet different needs of users.

[0077] Optionally, when the housing 10 has two fresh air inlets, the air duct switching device is configured with relatively independent first sub-fresh air ducts 6053 and second sub-fresh air ducts 6054. The first sub-fresh air ducts 6053 are communicated with one fresh air inlet, and the second sub-fresh air ducts 6054 are communicated with the other fresh air inlet. The air duct switching device is used to switch the first sub-fresh air ducts 6053 and / or the second sub-fresh air ducts 6054 to be communicated with the fresh air outlet 202.

[0078] The housing 10 has two fresh air inlets. For the convenience of description, the two fresh air inlets are defined as a first fresh air inlet 401 and a second fresh air inlet 501 respectively. Among them, the first fresh air inlet 401 is communicated with the first sub-fresh air ducts 6053, and the second fresh air inlet 501 is communicated with the second sub-fresh air ducts 6054. And the air flow from the first fresh air inlet 401 to the first sub-fresh air ducts 6053 is isolated from the air flow from the second fresh air inlet 501 to the second sub-fresh air ducts 6054.

[0079] In addition, it should be noted that the two fresh air inlets of the housing 10 are both communicated with the indoor environment. That is, the indoor air flows into the fresh air duct through the fresh air inlet and then flows out from the fresh air outlet 202. And the positions of the two fresh air inlets of the housing 10 are different. Exemplarily, the first fresh air inlet 401 is located at the top of the housing 10, and the second fresh air inlet 501 is located at the back or side of the housing 10.

[0080] When the air duct switching device switches the first sub-fresh air ducts 6053 to be communicated with the fresh air outlet 202, the indoor air flows into the first sub-fresh air ducts 6053 from the first fresh air inlet 401 and flows out from the fresh air outlet 202 under the action of the turbulence fan 601. At this time, the air path between the second sub-fresh air ducts 6054 and the fresh air outlet 202 is disconnected. That is, it can be understood that the air outlet of the second sub-fresh air ducts 6054 is closed.

[0081] When the air duct switching device switches the second sub-fresh air ducts 6054 to be communicated with the fresh air outlet 202, the indoor air flows into the second sub-fresh air ducts 6054 from the second fresh air inlet 501 and flows out from the fresh air outlet 202 under the action of the turbulence fan 601. At this time, the air path between the first sub-fresh air ducts 6053 and the fresh air outlet 202 is disconnected. That is, it can be understood that the air outlet of the first sub-fresh air ducts 6053 is closed.

[0082] When the air duct switching device switches so that both the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 are connected to the fresh air outlet 202, indoor air can not only flow in from the first fresh air inlet 401 and the first sub-fresh air duct 6053 and flow out from the fresh air outlet 202 under the action of the turbulence blower 601, but also flow in from the second fresh air inlet 501 and the second sub-fresh air duct 6054. It can be understood that some or all of the air outlets of the first sub-fresh air duct 6053 and some or all of the air outlets of the second sub-fresh air duct 6054 are connected to the fresh air outlet 202.

[0083] An embodiment of the present disclosure provides an air duct switching device, which includes: a first disk body 603 and a wind guiding part 605. The air duct switching device is provided on the front panel 20, and the user can manually adjust the air duct switching device to achieve the purpose of adjusting the air duct switching.

[0084] The first disk body 603 is configured with a hollow part communicating with the fresh air outlet 202. The edge of the hollow part extends to one side and forms a ventilation part 604 having a ventilation opening; the hollow part is located in the middle of the first disk body 603 and is coaxially arranged with the first disk body 603. The ventilation part extends from the disk surface of the first disk body 603 towards the fresh air duct, that is, the first disk body 603 faces the user, while the ventilation part faces away from the user.

[0085] The wind guiding part is configured with an independent first sub-fresh air duct 6053 and a second sub-fresh air duct 6054, and the air outlets of the first sub-fresh air duct 6053 and the air outlets of the second sub-fresh air duct 6054 are connected; wherein, the first disk body 603 and the wind guiding part can rotate relative to each other, and the ventilation opening 6041 of the ventilation part can be selectively connected to the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054.

[0086] When the first disk body 603 rotates, the ventilation part rotates with the first disk body 603, and the position of the ventilation opening changes with the rotation of the ventilation part. When the ventilation opening rotates to the air outlet of the first sub-fresh air duct 6053, the ventilation part communicates with the first sub-fresh air duct 6053, and the air in the first sub-fresh air duct 6053 flows through the ventilation part and flows out from the fresh air outlet 202; when the ventilation opening rotates to the air outlet of the second sub-fresh air duct 6054, the ventilation part 604 communicates with the second sub-fresh air duct 6054, and the air in the second sub-fresh air duct 6054 flows through the ventilation part and flows out from the fresh air outlet 202. In addition, when the ventilation opening 6041 rotates to the connection part between the air outlet of the first sub-fresh air duct 6053 and the air outlet of the second sub-fresh air duct 6054, part of the air outlet of the first sub-fresh air duct 6053 and part of the air outlet of the second sub-fresh air duct 6054 communicate with the ventilation opening 6041, so that the air in the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 can both flow out from the fresh air outlet 202 through the ventilation part.

[0087] By using the air duct switching device of the present disclosure embodiment, through the relative rotation of the first disk body 603 and the air guiding part, the ventilation opening 6041 of the ventilation part can be selectively communicated with the first sub-fresh air duct 6053 and / or the second fresh air duct, so as to achieve the purpose of selective air duct switching. Through different air inlet paths, not only can the range of the installation position of the air conditioner indoor unit be expanded, but also the different air outlet requirements of users can be met.

[0088] The first disk body 603 of this embodiment can be embedded in the front panel 20 and can rotate relative to the front panel 20. In this way, the user can manually rotate the first disk body 603 to achieve the purpose of switching the air duct.

[0089] Optionally, the ventilation area of the ventilation opening matches the ventilation area of the air outlet of the first sub-fresh air duct 6053; and / or, the ventilation area of the ventilation opening matches the ventilation area of the air outlet of the second sub-fresh air duct 6054.

[0090] The ventilation area of the ventilation opening matches the ventilation area of the air outlet of the first sub-fresh air duct 6053 and its ventilation area matches the ventilation area of the air outlet of the second sub-fresh air duct. In this way, when the ventilation opening corresponds to and communicates with the air outlet of the first sub-fresh air duct 6053, it not only ensures that the air flow in the first sub-fresh air duct 6053 can flow into the ventilation part through the ventilation opening without obstruction, but also can prevent the ventilation opening from being too large and communicating with the air outlet of the second sub-fresh air duct 6054. Similarly, when the ventilation opening corresponds to and communicates with the air outlet of the second sub-fresh air duct 6054, it not only ensures that the air flow in the second sub-fresh air duct 6054 can flow into the ventilation part through the ventilation opening without obstruction, but also can prevent the ventilation opening from being too large and communicating with the air outlet of the first sub-fresh air duct 6053.

[0091] Optionally, one end of the ventilation part 604 is communicated with the hollow part, and the other end is closed; wherein, the ventilation opening is arranged on the side wall of the ventilation part, and the area of the ventilation opening is less than or equal to one half of the area of the side wall of the ventilation part. In this way, the air in the air guiding part can only flow into the ventilation part through the ventilation opening formed by the side wall of the ventilation part, and flow in the direction of the fresh air outlet 202 until it is blown out of the air conditioner indoor unit.

[0092] The closed end of the ventilation part is adapted to the air outlet of the air guiding part, and the area of the ventilation opening is less than or equal to one half of the area of the side wall of the ventilation part, which can ensure that when the ventilation opening is correspondingly communicated with the air outlet of the first sub-fresh air duct 6053 / the second self-fresh air duct, the air outlet of the second sub-fresh air duct 6054 / the first sub-fresh air duct 6053 is in a closed state (blocked and closed by other side walls of the ventilation part).

[0093] Optionally, the ventilation part 604 is frustum-shaped, and the ventilation opening is fan-shaped, so that the air flow can flow from the air guiding part into the ventilation part through the ventilation opening.

[0094] The air guiding part 605 is buckled to the outside of the ventilation part. The frustum-shaped ventilation part and the fan-shaped ventilation opening can not only realize that when the ventilation opening is selectively communicated with the air outlet of the first sub-fresh air duct 6053 or the air outlet of the second sub-fresh air duct 6054, it is only communicated with one of the air outlets, but also facilitate the smooth flow of the air in the sub-fresh air duct through the ventilation opening. In addition, it is also beneficial to the assembly and relative rotation of the ventilation part and the air guiding part.

[0095] Optionally, the air guiding part 605 includes: a first sub-air guiding part 6051, which encloses a first sub-fresh air duct 6053; a second sub-air guiding part 6052, which encloses a second sub-fresh air duct 6054; wherein, the first sub-air guiding part 6051 and the second sub-air guiding part 6052 are spliced at the air outlet, and the air guiding part covers the ventilation part at the air outlet.

[0096] The first sub-air guiding part 6051 and the second sub-air guiding part 6052 are spliced at the air outlet, and the spliced air outlet is circular to match the ventilation part, so that the air guiding part covers the ventilation part and the purpose of relative rotation can be achieved.

[0097] The air inlets of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 respectively correspond to different fresh air inlets of the housing 10.

[0098] Combined Figure 16 As shown, the structures of the first sub-air guiding part 6051 and the second sub-air guiding part 6052 are the same. In practical applications, the air inlet of the first sub-air guiding part 6051 faces upward, and the air inlet of the second sub-air guiding part 6052 faces downward.

[0099] Optionally, the air duct switching device further includes: a mounting plate 606, disposed on the inner side wall of the front panel 20 and configured with an avoidance structure for avoiding the first disc body 603, so that the first disc body 603 can rotate relative to the mounting plate 606; wherein, the air guiding portion is disposed on the mounting plate 606 for fixation.

[0100] The ventilation portion of the first disc body 603 passes through the avoidance structure of the mounting plate 606, wherein the avoidance structure of the mounting plate 606 is adapted to the outer side wall of the ventilation portion to avoid the gap between the two being too large or too small.

[0101] The air guiding portion is fixedly installed through the mounting plate 606, thereby ensuring the positions of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 are determined. In practical applications, only by rotating the first disc body 603 and adjusting the position of the ventilation opening, the relative switching purpose of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 can be achieved.

[0102] Optionally, the air duct switching device further includes: a turbulence blower 601, disposed in the hollow portion of the first disc body 603, so that air is inhaled through the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 and blown out by the turbulence blower 601.

[0103] The air located in the air conditioner indoor unit flows in through the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 under the suction of the turbulence blower 601, and is blown out from the fresh air outlet 202 by the turbulence blower 601 through the ventilation portion.

[0104] Optionally, the air duct switching device further includes: a second disc body 607, covering the first disc body 603. A hollow portion is formed in the middle of the second disc body 607, and a plurality of air guiding members 602 are provided in the hollow portion to guide the flow direction of the air flow generated by the turbulence blower 601.

[0105] The second disc body 607 faces the user and can be fixedly arranged with the first disc body 603 or can rotate relative to it. The air guiding members 602 are used to guide the air flow blown out from the fresh air outlet 202, thereby guiding the flow direction of the air flow blown out by the turbulence blower 601. The air guiding members 602 can be understood as air guiding grilles. Among them, the hollow portion of the second disc body 607 can be understood as the fresh air outlet 202.

[0106] Optionally, a display screen is provided in the middle of the hollow portion of the second disc body 607, and the air guiding members 602 are arranged in a circumferential and radial manner around the display screen. Preferably, the plurality of air guiding members 602 are arranged in a spiral direction. As shown in combination Figure 6 shown.

[0107] In practical applications, the turbulence blower 601 can also be disposed on the second disc body 607.

[0108] Optionally, the air conditioner indoor unit further includes a front panel 20, and the first disk body 603 is disposed on the front panel 20 and is rotatable relative to the front panel 20.

[0109] The first disk body 603 is located on the front panel 20 and rotates relative to the front panel 20. In this way, it not only helps the airflow flowing out from the first disk body 603 to disturb the airflow flowing out from the main air outlet, but also facilitates the user to adjust the first disk body 603 to achieve the purpose of air duct switching.

[0110] Exemplarily, the first disk body 603 is passed through the front panel 20 and is rotatable relative to it.

[0111] In addition, the second disk body 607 is provided with a display screen, which also facilitates the user to observe the temperature and operating mode of the air conditioner, etc.

[0112] Combined with Figures 11 to 15 As shown, the embodiment of the present disclosure provides another air duct switching device, and the air duct switching device includes:

[0113] The movable ring 609 includes a conducting portion 610. The conducting portion defines a ventilation air duct, and a ventilation opening communicating with the ventilation air duct is formed on the side wall of the conducting portion;

[0114] The guiding portion 611 is slidable relative to the conducting portion 610. One end of the guiding portion 611 is closed, and first air vents 6111 and second air vents 6112 are formed on its side wall. The first air vents 6111 and the second air vents 6112 are arranged in a staggered manner, and the first air vents 6111 and the second air vents 6112 are used to communicate with different fresh air vents;

[0115] Wherein, the movable ring 609 is slidable relative to the guiding portion 611, so that the ventilation opening 6101 of the conducting portion can be selectively communicated with the first air vent 6111 and / or the second air vent 6112.

[0116] By using the air duct switching device provided by the embodiment of the present disclosure, the movable ring 609 drives the conducting portion to slide, that is, the conducting portion slides relative to the guiding portion 611, so that the ventilation opening 6101 of the conducting portion can be selectively communicated with the first air vent 6111 and / or the second air vent 6112. The first air vents 6111 and the second air vents 6112 are used to communicate with different fresh air vents, so as to achieve the purpose of selective air duct switching. Through different air inlet paths, not only can the range of installation positions of the air conditioner indoor unit be expanded, but also the different air outlet requirements of users can be met.

[0117] When the movable ring 609 slides, the conduction part slides with the movable ring 609, and the position of the ventilation opening changes with the movement of the conduction part. When the ventilation opening moves to the first air outlet 6111, the conduction part communicates with the first air outlet 6111, so as to communicate with the first fresh air inlet 401 connected to the first air outlet 6111; when the ventilation opening moves to the second air outlet 6112, the conduction part communicates with the second air outlet 6112, so as to communicate with the second fresh air inlet 501 connected to the first air outlet 6111. When the ventilation opening moves to a position where it is partially connected to the first air outlet 6111 and partially connected to the second air outlet 6112, the conduction part is not only connected to the first fresh air inlet 401, but also connected to the second fresh air inlet 501.

[0118] In this embodiment, the movable ring 609 is embedded in the front panel 20 and can slide relative to the front panel 20. In this way, the user can manually push and pull the movable ring 609 to achieve the purpose of switching the air duct.

[0119] Optionally, along the direction perpendicular to the front panel 20, the distance from the first air outlet 6111 to the front panel 20 is less than the distance from the second air outlet 6112 to the front panel 20. The first air outlet 6111 is closer to the front panel 20 than the second air outlet 6112. The first air outlet 6111 and the second air outlet 6112 are arranged one in front of the other. When the conduction part moves back and forth, the ventilation opening 6101 of the conduction part is selectively connected to the first air outlet 6111 and / or the second air outlet 6112.

[0120] Optionally, along the direction perpendicular to the front panel 20, when the movable ring 609 slides to the first position, the ventilation opening 6101 of the conduction part communicates with the first air outlet 6111; when the movable ring 609 slides to the second position, the air inlet of the ventilation air duct of the conduction part communicates with the second air outlet 6112, and the ventilation opening 6101 of the conduction part communicates with the first air outlet 6111; when the movable ring 609 slides to the third position, the air inlet of the ventilation air duct of the conduction part communicates with the second air outlet 6112, and the side wall of the conduction part is arranged corresponding to the first air outlet 6111 to close the first air outlet 6111. In this way, the purpose of selective switching of the air duct is achieved.

[0121] Optionally, the guiding part 611 is sleeved on the conduction part. When the movable ring 609 slides inward and the ventilation opening is arranged corresponding to the second air outlet 6112, the conduction part abuts against the guiding part 611.

[0122] When the movable ring 609 slides inward and the ventilation opening is correspondingly arranged with the second air outlet 6112, the conduction part is limited by abutting against the diversion part 611, preventing the movable ring 609 from continuing to slide, thereby reminding the user that the ventilation opening has been correspondingly arranged with the second air outlet 6112 and the air duct switching is completed, avoiding the misalignment of the ventilation opening and the second air outlet 6112 caused by excessive sliding, and thus reducing the ventilation volume.

[0123] Optionally, the ventilation area of the ventilation opening 6101 of the conduction part, the ventilation area of the first air outlet 6111 and / or the ventilation area of the second air outlet 6112 are equal. In this way, when the first air outlet 6111 is correspondingly arranged with the ventilation opening 6101 of the conduction part or the second air outlet 6112 is correspondingly arranged with the ventilation opening 6101 of the conduction part, it not only helps to ensure the ventilation volume, but also can prevent the air flow of the non-correspondingly arranged air outlet from flowing into the conduction part.

[0124] Optionally, the first air outlet 6111 is located above the second air outlet 6112. In this way, the first air outlet 6111 and the second air outlet 6112 do not interfere with each other, and respectively correspond to different fresh air inlets, which can ensure different air inlet paths.

[0125] In this embodiment, the first air outlet 6111 communicates with the first fresh air inlet 401 of the housing 10, and the second air outlet 6112 communicates with the second fresh air inlet 501 of the housing 10.

[0126] Optionally, the end of the diversion part 611 with a closed setting is provided with a positioning structure 6113, and the end of the conduction part is provided with a matching structure 6102. The matching structure 6102 is adapted to the positioning structure 6113 so as to position and install the diversion part 611 and the conduction part.

[0127] When the diversion part 611 and the conduction part are assembled, through the positioning structure 6113 and the matching structure 6102, the relative position relationship between the diversion part 611 and the conduction part is correct, avoiding deviation and resulting in the non-correspondence between the ventilation opening and the first air outlet 6111 or the second air outlet 6112.

[0128] Exemplarily, the positioning structure 6113 and the matching structure 6102 can be positioning grooves or positioning posts, or the positioning structure 6113 and the matching structure 6102 are positioning notches and positioning protrusions.

[0129] Optionally, the diversion part 611 abuts against the partition 30, and the positioning structure 6113 is adapted to the structure of the partition 30.

[0130] The diversion part 611 abuts against the partition plate 30. The partition plate 30 plays a certain supporting role for the closed end of the diversion part 611, which helps to further install and fix the diversion part 611, and avoids the shaking of the closed end of the diversion part 611 when the conduction part moves. In addition, by adapting the positioning structure 6113 to the structure of the partition plate 30, the fixing effect of the diversion part 611 can be further enhanced and the positioning accuracy of the diversion part 611 can be improved during assembly.

[0131] Optionally, the air duct switching device of this embodiment further includes: a fixing ring 612, which is arranged on the front panel 20 of the air conditioner and is hollow in the middle; wherein, the movable ring 609 further includes a ring body located on the air outlet side of the conduction part, and the conduction part of the movable ring 609 passes through the hollow area in the middle of the fixing ring 612, and the ring body of the movable ring 609 covers the outer surface of the ring body of the fixing ring 612.

[0132] The ring body of the movable ring 609 covers the outer surface of the ring body of the fixing ring 612, and its relative connection with the front panel 20 is realized through the fixing ring 612. The movable ring 609 moves back and forth relative to the fixing ring 612 to change the position of the ventilation opening, so as to achieve the purpose of switching the air duct.

[0133] Optionally, the air duct switching device further includes: a spoiler fan 601, which is arranged at the air outlet of the conduction part, so that air is sucked in through the first air outlet 6111 and / or the second air outlet 6112 and blown out by the spoiler fan 601.

[0134] The air located in the indoor unit of the air conditioner flows in through the first air outlet 6111 and / or the second air outlet 6112 under the suction of the spoiler fan 601, passes through the conduction part, and is blown out from the fresh air outlet 202 by the spoiler fan 601.

[0135] Optionally, the air duct switching device further includes: a wind guiding member 613, which is arranged at the air outlet of the conduction part and on the air outlet side of the spoiler fan. In this way, the airflow blown out from the air outlet of the conduction part is guided, so as to guide the flow direction of the airflow blown out by the spoiler fan 601. The wind guiding member 613 can be understood as a wind guiding grille.

[0136] This embodiment of the present disclosure also provides an indoor unit of an air conditioner, including: a housing 10, a partition plate 30, a top plate 40 and a middle plate 50, which play a role in supporting and installing various components of the indoor unit of the air conditioner.

[0137] The housing 10 defines an accommodation cavity; the partition plate 30 is arranged in the accommodation cavity and divides the accommodation cavity into independent heat exchange air ducts 101 and fresh air ducts; the top plate 40 is arranged on the top of the housing 10; the middle plate 50 is arranged in the housing 10 and at the bottom of the partition plate 30; wherein, the top plate 40 and / or the middle plate 50 are configured with fresh air vents communicating with the fresh air duct.

[0138] Using the air conditioner indoor unit of the embodiments of the present disclosure, the heat exchange air duct 101 and the fresh air duct are independently arranged, and the heat exchange air duct 101 and the fresh air duct blow out air respectively, which can bring different usage experiences to users. In addition, the top plate 40 and / or the middle plate 50 are configured with fresh air inlets communicating with the fresh air duct. Different air inlet paths can not only expand the range of installation positions of the air conditioner indoor unit, but also meet the different air outlet requirements of users.

[0139] The shape and structure of the partition 30 in this embodiment are adapted to the installation position and size of the cross-flow fan 90.

[0140] For the convenience of description, the fresh air inlet on the top plate 40 is defined as the first fresh air inlet 401 of the housing 10, and the fresh air inlet on the middle plate 50 is defined as the second fresh air inlet 501 of the housing 10.

[0141] The first fresh air inlet 401 and the second fresh air inlet 501 are only connected to the fresh air duct.

[0142] Optionally, when the top plate 40 is configured with a fresh air inlet, it further includes: an air guiding part 402, one end of which abuts against the top plate 40 and the other end abuts against the partition 30; and the air duct surrounded by the air guiding part 402 communicates with the fresh air inlet on the top plate 40, so that the air flowing in from the fresh air inlet on the top plate 40 is guided by the air guiding part 402 into the fresh air duct.

[0143] In practical applications, for the convenience of assembly, there is a gap between the top of the partition 30 and the top plate 40. Therefore, when the first fresh air inlet 401 is configured on the top plate 40, the air flowing in from the first fresh air inlet 401 will not only flow into the fresh air duct, but also flow into the heat exchange air duct 101. By providing the air guiding part 402, the flow path of the air flowing to the heat exchange air duct 101 can be closed, so that all the air flowing in from the first fresh air inlet 401 on the top plate 40 flows into the fresh air duct.

[0144] One end of the air guiding part 402 abuts against the top plate 40 and the other end abuts against the partition 30, which can improve the stability of the air guiding part 402 during use and avoid displacement under the influence of wind force.

[0145] Optionally, when the middle plate 50 is configured with a fresh air inlet, it further includes: an air guiding pipe 502, one end of which is connected to the middle plate 50 and communicates with the fresh air inlet on the middle plate 50, and the other end is connected to the main air inlet 103 of the air conditioner indoor unit, so that part of the air flow at the main air inlet 103 is blown out through the fresh air duct; wherein, the main air inlet 103 of the air conditioner indoor unit is connected to the heat exchange air duct 101.

[0146] The main air inlet 103 of the air conditioner indoor unit is communicated with the heat exchange air duct 101, and the air flowing in from the main air inlet 103 flows into the heat exchange air duct 101. In this embodiment, through the air guide pipe 502, part of the air flowing in from the main air inlet 103 is diverted to the second fresh air inlet 501 of the middle plate 50 and the fresh air duct, so as to realize different air inlet paths of the fresh air duct.

[0147] By using the air guide pipe 502, it is possible to avoid the occurrence of turbulent flow of the fresh air before it flows into the fresh air duct, and also avoid affecting the air flow flowing into the heat exchange air duct 101.

[0148] Optionally, the housing 10 further includes: a front panel 20, which encloses a fresh air duct with the partition plate 30, the top plate 40 and the middle plate 50;

[0149] Among them, the front panel 20 is configured with a main air outlet and a fresh air outlet 202. The main air outlet is communicated with the heat exchange air duct 101, and the fresh air outlet 202 is communicated with the fresh air duct.

[0150] The space between the partition plate 30 and the front panel 20 is the fresh air duct. The heat exchange air duct 101 and the fresh air duct are arranged at intervals through the partition plate 30 to prevent the air flow in the heat exchange air duct 101 and the air flow in the fresh air duct from mixing, so as to affect the temperature, flow rate and velocity of the air flow at the main air outlet and the fresh air outlet 202.

[0151] The air flow flowing out from the fresh air outlet 202 disturbs the air flow flowing out from the main air outlet, so that a "pear-shaped" air flow swirl is formed near the air conditioner indoor unit, which not only expands the radiation range of the air flow, but also helps to improve the uniformity of the indoor temperature.

[0152] Optionally, the air conditioner indoor unit further includes: a flow disturbing device, which is arranged in the fresh air outlet 202 of the front panel 20 and the fresh air duct. The flow disturbing device includes a flow disturbing fan 601 to suck air from the fresh air outlet into the fresh air duct and blow it out from the fresh air outlet 202.

[0153] The flow disturbing fan 601 also increases the disturbing force of the indoor air flow, accelerates the air flow to flow back to the main air inlet 103 of the air conditioner, and is beneficial to the uniformity of the indoor environmental temperature. In practical applications, after the air flow blown out from the flow disturbing fan 601 reaches a certain position in the room, it decelerates under the action of the return flow blown out by the cross-flow fan 90 of the air conditioner and flows back to the main air outlet of the air conditioner, mixes with the air flow blown out at the main air outlet, and participates in the indoor air circulation again.

[0154] Optionally, when fresh air inlets are provided in both the top plate 40 and the middle plate 50, it can be understood that the housing 10 has two fresh air inlets. The flow disturbance device further includes: a duct switching device configured with independent first sub-fresh air ducts 6053 and second sub-fresh air ducts 6054. The first sub-fresh air duct 6053 is communicated with the fresh air inlet of the top plate 40, and the second sub-fresh air duct 6054 is communicated with the fresh air inlet of the middle plate 50. The duct switching device is used to switch the connection of the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 to the fresh air outlet 202.

[0155] Through the duct switching device, not only can the on-off of the air path of the fresh air duct be controlled, but also different air inlet paths can be selected, so as to meet different needs of users.

[0156] Optionally, when a fresh air inlet is provided in the top plate 40 or the middle plate 50, the flow disturbance device further includes: a duct switching device disposed in the fresh air duct for controlling the on-off of the air path of the fresh air duct. By means of the duct switching device, the on-off of the air path of the fresh air duct can be controlled, so as to control the air volume output of the fresh air outlet 202 and meet different needs of users.

[0157] The embodiment of the present disclosure further provides a flow disturbance device, including: a first disk body 603 and a second disk body 607.

[0158] The first disk body 603 is configured with a hollow part for installing a flow disturbance fan 601; the second disk body 607 is rotatable relative to the first disk body 603 and is located on the air outlet side of the first disk body 603; wherein, a hollow part is configured in the middle of the second disk body 607, and a plurality of air guiding members 602 are arranged in the hollow part to guide the air flow generated by the flow disturbance fan 601.

[0159] By adopting the flow disturbance device of the embodiment of the present disclosure, through the flow disturbance effect of the flow disturbance fan 601, the air flow rate and velocity in the indoor corners are increased, a plurality of air flow vortices are formed indoors, and the air flow vortices in the indoor corners are complete and smooth; and by rotating the second disk body 607 relative to the first disk body 603, the air guiding direction of the air guiding members 602 is adjusted, so as to guide the air flow generated by the flow disturbance fan 601; cooperating with the flow disturbance fan 601, a "pear-shaped" air flow vortex is further formed in a specific area around the indoor unit of the air conditioner, strengthening or selectively expanding the influence range of the air flow.

[0160] In practical applications, when the second disk body 607 is rotated by a certain angle, the air guiding direction of the air guiding members 602 is changed, so that an air flow vortex can be formed in a specific area around the outdoor unit of the air conditioner or it can be understood that the air flow in a certain direction is disturbed, which helps to bring different usage experiences to users.

[0161] Optionally, the hollow portion of the second disk body 607 is circular. Along the radial direction, the lengths of the plurality of air guiding members 602 gradually increase first and then gradually decrease. The flow areas between adjacent air guiding members 602 are different, so that the air flow rates blown out between different air guiding members 602 are different. The air flows in different directions and with different flow rates are blown out simultaneously, which helps to further improve the turbulence effect.

[0162] Optionally, the air guiding member 602 is arc-shaped, so that the flow directions of the air flow blown out from the same gap are not all the same, further improving the turbulence effect; and / or, the bending directions of the plurality of air guiding members 602 are the same. In this way, it is possible to avoid the occurrence of turbulence between the air flows blown out from the hollow portion of the second disk body 607, which affects the air supply distance. That is, it is ensured that at least most of the air flow blown out from the hollow portion of the second disk body 607 can be mixed with the air flow blown out from the main air outlet and disturb the original flow direction of the air flow.

[0163] Optionally, the distances between some or all of the air guiding members 602 are equal. The equal distances between all the air guiding members 602 help to improve the appearance beauty of the indoor unit, but the equal distances between some of the air guiding members 602 can be understood as at least two distance dimensions, which helps to improve the turbulence effect of the turbulence device on the air flow blown out from the main air outlet.

[0164] Optionally, the annular side wall of the first disk body 603 and / or the annular side wall of the second disk body 607 are configured with a convex structure 608 for anti-slip. Through the convex structure 608, the problem of slipping can be avoided when the first disk body 603 or the second disk body 607 is rotated.

[0165] Optionally, the first disk body 603 and the second disk body 607 are arranged on the front panel 20, and the second disk body 607 covers the air outlet side of the first disk body 603; wherein, the first disk body 603 and the second disk body 607 can rotate relative to the front panel 20 respectively.

[0166] In this embodiment, the purpose of switching the fresh air duct is achieved by rotating the first disk body 603, and the purpose of adjusting the turbulence direction is achieved by rotating the second disk body 607. The two cooperate with each other, which can not only achieve the turbulence purpose, but also strengthen the turbulence effect in a specific area, meeting different usage requirements of users.

[0167] The embodiment of the present disclosure also provides an air conditioner indoor unit, including: a housing 10, a partition 30, a middle plate 50, and a purification module 70.

[0168] The housing 10 defines an accommodation cavity; the partition plate 30 is disposed in the accommodation cavity and divides the accommodation cavity into independent heat exchange air ducts 101 and fresh air ducts 102; the middle plate 50 is disposed in the housing 10 and at the bottom of the partition plate 30, and the middle plate 50 is configured with a fresh air inlet; the purification module 70 is correspondingly disposed with the fresh air inlet of the middle plate 50 to purify the air flow flowing into the fresh air duct 102.

[0169] By using the air conditioner indoor unit provided by the embodiment of the present disclosure, the heat exchange air duct 101 and the fresh air duct are independently arranged, and the heat exchange air duct 101 and the fresh air duct blow out air respectively, which can bring different use experiences to users. In addition, the middle plate 50 is configured with a fresh air inlet communicating with the fresh air duct, and the air flow flowing into the fresh air inlet and the fresh air duct is purified by the purification module 70, which helps to improve the cleanliness of the air blown out from the fresh air duct, thereby enhancing the user experience.

[0170] Optionally, the air conditioner indoor unit further includes: an air guiding pipe 502, one end of which is connected to the middle plate 50 and communicates with the fresh air inlet of the middle plate 50, and the other end of which communicates with the main air inlet 103 of the air conditioner indoor unit, so that a part of the air flow at the main air inlet 103 is blown out through the fresh air duct; wherein, the main air inlet 103 of the air conditioner indoor unit communicates with the heat exchange air duct 101.

[0171] The main air inlet 103 of the air conditioner indoor unit communicates with the heat exchange air duct 101, and the air flowing in from the main air inlet 103 flows into the heat exchange air duct 101. In this embodiment, through the air guiding pipe 502, a part of the air flowing in from the main air inlet 103 is diverted to the second fresh air inlet 501 of the middle plate 50 and the fresh air duct, thereby realizing different air inlet paths of the fresh air duct.

[0174] Optionally, when the purification module 70 is disposed above or below the middle plate 50, the purification module 70 penetrates through the housing 10 and is pullable for replacement.

[0175] Through the pull-out setting of the purification module 70, it is convenient for its replacement, thereby ensuring the cleanliness of the air flowing into the fresh air duct.

[0176] Optionally, when the purification module 70 is disposed below the middle plate 50, the air guide pipe 502 is connected to the purification module 70, so that the air in the air guide pipe 502 flows into the fresh air duct after being purified by the purification module 70.

[0177] Exemplarily, the purification module 70 is located between the air guide pipe 502 and the middle plate 50, or the purification module 70 is inserted into the air guide pipe 502, so as to ensure that the air in the air guide pipe 502 flows into the fresh air duct after being purified by the purification module 70.

[0178] Optionally, the indoor air conditioner further includes: a water washing module 80, which is located below the purification module 70 and the purification module 70 is located below the middle plate 50, so that the air flow entering from the independent air inlet 103 flows into the heat exchange duct 101 after passing through the water washing module 80 and the purification module 70 in sequence.

[0179] The air flowing into the heat exchange duct 101 is purified by water washing through the water washing module 80, and cooperates with the purification module 70 to ensure the cleanliness of the air flow blown out from the independent air outlet and the fresh air outlet 202 when the indoor air conditioner has a flow disturbance function.
