Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example, to an indoor air conditioning unit. Background Technology

[0002] Currently, existing air conditioners blow out the air after heat exchange through the conventional air outlet. This conventional air outlet method is called conventional air outlet. The airflow from the conventional air outlet is fixed and has a limited radiation range. It cannot achieve large-scale, long-distance air delivery and has the problem of uneven air delivery, which reduces the user experience.

[0003] In related technologies, air conditioners are equipped with fresh air vents that work in conjunction with regular air vents to enable the air conditioner to have a fresh air function. However, the air flowing out of the fresh air vents is recirculated indoor air with poor cleanliness, which can easily reduce the user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments.

[0063] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0064] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0065] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0066] The indoor unit of the air conditioner provided in this embodiment can be a cabinet air conditioner. When the indoor unit of the air conditioner in this embodiment is cooling or heating, the airflow is turbulent by a turbulence device, forming a "pear-shaped" airflow vortex near the indoor unit, which expands the radiation range of the airflow. This not only helps to improve the efficiency of indoor heating or cooling, but also helps to make the indoor temperature more uniform.

[0067] Combination Figures 1 to 17 As shown, this embodiment of the present disclosure provides an indoor air conditioning unit, including: a housing 10, a front panel 20, and a deflector.

[0068] The housing 10 encloses a heat exchange duct 101; a cross-flow fan 90 is installed inside the heat exchange duct 101, wherein this embodiment uses a dual cross-flow fan 90 as an example. The front panel 20 is connected to the housing 10 and faces the user. The front panel 20 may be equipped with a display screen to display the temperature and the air conditioner's operating mode, etc. The front panel 20 is constructed with a main air outlet and a fresh air outlet 202; the main air outlet is connected to the heat exchange duct 101, and the cross-flow fan 90 blows the airflow in the heat exchange duct 101 out through the main air outlet to cool or heat the indoor environment. The turbulence device includes a turbulence fan 601, which is located on the front panel 20 and connected to the fresh air outlet 202. The duct where the turbulence device is located is independently set up from the heat exchange duct 101. When the main air outlet is venting, the airflow generated by the turbulence fan 601 is blown out from the fresh air outlet 202 to disturb the flow direction of the airflow at the main air outlet.

[0069] The air duct where the turbulence device is located is set independently from the heat exchange air duct 101. In this way, the airflow flowing through the turbulence fan 601 and the airflow flowing through the cross-flow fan 90 do not affect each other. The turbulence fan 601 blows the airflow out from the fresh air outlet 202, and the cross-flow fan 90 blows the airflow out from the main air outlet.

[0070] When both the turbulence fan 601 and the cross-flow fan 90 are turned on simultaneously, a pear-shaped airflow vortex is formed around the indoor unit of the air conditioner, expanding the range of airflow influence. Compared to turning on only the cross-flow fan 90, the turbulence effect of the turbulence fan 601 increases the airflow and velocity in the corners of the room, forming multiple airflow vortices in the room, and the airflow vortices in the corners of the room are complete and smooth.

[0071] In addition, the turbulence fan 601 increases the turbulence force of the indoor airflow, accelerating the airflow back to the main air inlet 103 of the air conditioner, which is beneficial to the uniformity of the indoor ambient temperature. In practical applications, the airflow blown out from the turbulence fan 601 reaches a certain position in the room, and is slowed down by the backflow action of the air conditioner cross-flow fan 90, and flows back to the main air outlet of the air conditioner, where it mixes with the airflow blown out from the main air outlet and participates in the indoor air circulation again.

[0072] When the air conditioner indoor unit provided in this embodiment is used, and the turbulence fan 601 and the cross-flow fan 90 are turned on at the same time, the airflow blown out by the turbulence fan 601 disturbs the airflow flowing out of the main air outlet, so that a "pear-shaped" airflow vortex is formed near the air conditioner indoor unit, which not only expands the radiation range of the airflow, but also helps to improve the uniformity of indoor temperature.

[0073] Optionally, the main air outlet includes a first air outlet 2011 and a second air outlet 2012 symmetrically arranged, both of which are connected to the heat exchange duct 101; wherein, the fresh air outlet 202 is located between the first air outlet 2011 and the second air outlet 2012.

[0074] The first air outlet 2011 and the second air outlet 2012 are 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 is venting air, it can simultaneously affect the airflow of the first air outlet 2011 and the second air outlet 2012, so as to further enhance the turbulence effect.

[0075] The first air outlet 2011 and the second air outlet 2012 are located near the edge of the air conditioner. The airflow from the first air outlet 2011 and the second air outlet 2012 flows to the surrounding area and then flows back to the air inlet of the air duct where the turbulence fan 601 is located.

[0076] Furthermore, with the turbulence fan 601 activated, it can directly supply air to the space directly opposite the front panel 20 through the fresh air outlet 202. This not only avoids the discomfort caused by direct airflow from the first air outlet 2011 and the second air outlet 2012, but also reduces airflow turbulence in the directly opposite space, increases airflow flow, and makes the indoor temperature distribution more uniform. In addition, it can also perform some cooling, reducing the energy consumption of the cross-flow fan 90 and achieving energy conservation and emission reduction.

[0077] The distance from the fresh air outlet 202 to the first air outlet 2011 is equal to the distance from it to the second air outlet 2012. This ensures the uniformity of the airflow disturbance to the first air outlet 2011 and the second air outlet 2012, thereby ensuring that the overall stress on the indoor unit of the air conditioner is uniform.

[0078] Optionally, the indoor unit of the air conditioner also includes: a partition 30 disposed inside the housing 10, which divides the receiving 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 connected to the fresh air outlet 202, and the turbulence device is located inside the fresh air duct.

[0079] The space between the partition 30 and the front panel 20 is a fresh air duct. The partition 30 separates the heat exchange duct 101 and the fresh air duct to prevent the airflow in the heat exchange duct 101 from mixing with the airflow in the fresh air duct, thereby affecting the temperature, flow rate and velocity of the airflow at the main air outlet and the fresh air outlet 202.

[0080] The turbulence device is located inside the fresh air duct and is used to blow the air in the fresh air duct out of the fresh air outlet 202, thus disturbing the airflow direction of the air blown out of the fresh air outlet.

[0081] Optionally, the turbulence device further includes: a plurality of air guide components 602, disposed at the fresh air outlet 202, to guide the airflow direction generated by the turbulence fan 601.

[0082] In this embodiment, multiple air guide components 602 are disposed at the fresh air outlet 202 to guide the airflow blowing out of the fresh air outlet 202, thereby guiding the direction of the airflow blown out by the turbulence fan 601. The air guide component 602 can be understood as an air guide grille.

[0083] Optionally, the air guide component 602 is arranged radially around the circumference of the fresh air outlet 202. In this way, guided by the air guide component 602, the airflow from the fresh air outlet 202 is blown out in a spiral shape.

[0084] Optionally, a display screen is provided at the fresh air outlet 202, and the air guiding components 602 are arranged radially around the circumference of the display screen. Preferably, multiple air guiding components 602 are arranged in a spiral direction. Figure 6 As shown.

[0085] Optionally, the turbulence device further includes: an air duct switching device, located within the fresh air duct, for controlling the flow of air in and out of the fresh air duct. The air duct switching device controls the flow of air in and out of the fresh air duct, thereby controlling the air volume output from the fresh air outlet 202 to meet different user needs.

[0086] Optionally, when the housing 10 has two fresh air inlets, the duct switching device is constructed with a relatively independent first sub-fresh air duct 6053 and a second sub-fresh air duct 6054. The first sub-fresh air duct 6053 is connected to one fresh air inlet, and the second sub-fresh air duct 6054 is connected to another fresh air inlet. The duct switching device is used to switch the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 to be connected to the fresh air outlet 202.

[0087] The housing 10 has two fresh air inlets, which are defined as a first fresh air inlet 401 and a second fresh air inlet 501 for ease of description. The first fresh air inlet 401 is connected to a first sub-fresh air duct 6053, and the second fresh air inlet 501 is connected to a second sub-fresh air duct 6054. Furthermore, the airflow from the first fresh air inlet 401 to the first sub-fresh air duct 6053 is isolated from the airflow from the second fresh air inlet 501 to the second sub-fresh air duct 6054.

[0088] Additionally, it should be noted that both fresh air inlets of the housing 10 are connected to the indoor environment. That is, indoor air flows into the fresh air duct through the fresh air inlets and then flows out from the fresh air outlet 202. Furthermore, the two fresh air inlets of the housing 10 are located in different positions. For example, 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.

[0089] When the air duct switching device connects the first sub-fresh air duct 6053 to the fresh air outlet 202, indoor air flows into the first sub-fresh air duct 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 duct 6054 and the fresh air outlet 202 is disconnected. That is to say, the outlet of the second sub-fresh air duct 6054 is closed.

[0090] When the air duct switching device connects the second sub-fresh air duct 6054 to the fresh air outlet 202, indoor air flows into the second sub-fresh air duct 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 duct 6053 and the fresh air outlet 202 is disconnected. That is to say, the outlet of the first sub-fresh air duct 6053 is closed.

[0091] When the air duct switching device connects both the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 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 fan 601, but also flow in from the second fresh air inlet 501 and the second sub-fresh air duct 6054. This can be understood as some or all of the outlets of the first sub-fresh air duct 6053 and some or all of the outlets of the second sub-fresh air duct 6054 being connected to the fresh air outlet 202.

[0092] This disclosure provides an air duct switching device, which includes a first disc 603 and an air guide 605. The air duct switching device is located 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.

[0093] The first plate 603 has a hollow section communicating with the fresh air outlet 202. The edge of the hollow section extends to one side to form a ventilation section 604 with a vent. The hollow section is located in the middle of the first plate 603 and is coaxially arranged with the first plate 603. The ventilation section extends from the plate surface of the first plate 603 towards the fresh air duct, that is, the first plate 603 faces the user, while the ventilation section faces away from the user.

[0094] The air guide section is constructed with an independent first sub-fresh air duct 6053 and a second sub-fresh air duct 6054. The air outlets of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 are connected. The first plate 603 and the air guide section are rotatable relative to each other. The ventilation port 6041 of the ventilation section can selectively connect with the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054.

[0095] When the first plate 603 rotates, the ventilation section rotates with the first plate 603, and the position of the ventilation opening changes with the rotation of the ventilation section. When the ventilation opening rotates to the air outlet of the first sub-fresh air duct 6053, the ventilation section is connected to the first sub-fresh air duct 6053, and the air in the first sub-fresh air duct 6053 flows through the ventilation section 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 section 604 is connected to the second sub-fresh air duct 6054, and the air in the second sub-fresh air duct 6054 flows through the ventilation section and flows out from the fresh air outlet 202. In addition, at the junction of the vent 6041 and the outlet of the first sub-fresh air duct 6053 and the outlet of the second sub-fresh air duct 6054, part of the outlet of the first sub-fresh air duct 6053 and part of the outlet of the second sub-fresh air duct 6054 are connected to the vent 6041. Then, the air in the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 can flow out from the fresh air outlet 202 through the ventilation section.

[0096] The air duct switching device of this embodiment rotates relative to the air guide section through the first plate 603, so that the ventilation port 6041 of the ventilation section can selectively connect with the first sub-fresh air duct 6053 and / or the second fresh air duct, thereby achieving the purpose of selective air duct switching. Through different air intake paths, not only can the range of installation locations of the indoor unit of the air conditioner be expanded, but also different air outlet needs of users can be met.

[0097] In this embodiment, the first disc 603 can be embedded in the front panel 20 and can rotate relative to the front panel 20. In this way, the user can switch the air duct by manually rotating the first disc 603.

[0098] Optionally, the ventilation area of ​​the vent is matched with the ventilation area of ​​the outlet of the first sub-fresh air duct 6053; and / or, the ventilation area of ​​the vent is matched with the ventilation area of ​​the outlet of the second sub-fresh air duct 6054.

[0099] The ventilation area of ​​the vent is matched with the air outlet of the first sub-fresh air duct 6053 and the air outlet of the second sub-fresh air duct. This ensures that, when the vent is connected to the air outlet of the first sub-fresh air duct 6053, it not only guarantees unobstructed airflow from the first sub-fresh air duct 6053 into the ventilation section, but also prevents the vent from being too large and connecting with the air outlet of the second sub-fresh air duct 6054. Similarly, when the vent is connected to the air outlet of the second sub-fresh air duct 6054, it not only ensures unobstructed airflow from the second sub-fresh air duct 6054 into the ventilation section, but also prevents the vent from being too large and connecting with the air outlet of the first sub-fresh air duct 6053.

[0100] Optionally, one end of the ventilation section 604 is connected to the hollow section, and the other end is closed; wherein the vent is opened on the side wall of the ventilation section, and the area of ​​the vent is less than or equal to half the area of ​​the side wall of the ventilation section. In this way, the air in the air guide section can only flow into the ventilation section through the vent constructed on the side wall of the ventilation section, and flows towards the fresh air outlet 202 until it is blown out of the indoor unit of the air conditioner.

[0101] The closed end of the ventilation section is adapted to the air outlet of the air guide section. The area of ​​the ventilation outlet is less than or equal to half of the area of ​​the side wall of the ventilation section, which can ensure that when the ventilation outlet is connected to the air outlet of the first sub-fresh air duct 6053 / the second sub-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 (closed by other side walls of the ventilation section).

[0102] Optionally, the ventilation section 604 is frustum-shaped, and the ventilation opening is fan-shaped, so that airflow flows from the air guide section into the ventilation section through the ventilation opening.

[0103] The air guide 605 is fastened to the outside of the ventilation section. The frustum-shaped ventilation section and the fan-shaped air vent not only allow the air vent to selectively connect to only one air vent when it connects to the air outlet of the first sub-fresh air duct 6053 or the air outlet of the second sub-fresh air duct 6054, but also facilitate the smooth flow of air within the sub-fresh air duct through the air vent. In addition, it also facilitates the assembly and relative rotation of the ventilation section and the air guide.

[0104] Optionally, the air guide 605 includes: a first sub-air guide 6051, which encloses a first sub-fresh air duct 6053; and a second sub-air guide 6052, which encloses a second sub-fresh air duct 6054; wherein the first sub-air guide 6051 and the second sub-air guide 6052 are spliced ​​together at the air outlet, and the air guide is covered by the ventilation section at the air outlet.

[0105] The first sub-air guide 6051 and the second sub-air guide 6052 are spliced ​​together at the air outlet. The spliced ​​air outlet is circular to match the ventilation section, so that the air guide is covered by the ventilation section and can be rotated relative to it.

[0106] The air inlet of the first sub-fresh air duct 6053 and the air inlet of the second sub-fresh air duct 6054 correspond to different fresh air inlets of the housing 10.

[0107] Combination Figure 16 As shown, the first sub-air guide 6051 and the second sub-air guide 6052 have the same structure. In practical applications, the air inlet of the first sub-air guide 6051 faces upward, and the air inlet of the second sub-air guide 6052 faces downward.

[0108] Optionally, the air duct switching device further includes: a mounting plate 606, disposed on the inner side wall of the front panel 20, and having a clearance structure to avoid the first disc 603, so that the first disc 603 can rotate relative to the mounting plate 606; wherein, the air guide is disposed on the mounting plate 606 for fixation.

[0109] The ventilation section of the first disc 603 passes through the clearance structure of the mounting plate 606, wherein the clearance structure of the mounting plate 606 is adapted to the outer wall of the ventilation section to avoid the gap between the two being too large or too small.

[0110] The air guide is fixedly installed by the mounting plate 606, thereby ensuring that the positions of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 are determined. In practical applications, the relative switching of the first sub-fresh air duct 6053 and the second sub-fresh air duct 6054 can be achieved simply by rotating the first plate 603 and adjusting the position of the vent.

[0111] Optionally, the air duct switching device further includes: a turbulence fan 601, located in the hollow part of the first plate 603, so that air is drawn in through the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 and blown out by the turbulence fan 601.

[0112] Air located in the indoor unit of the air conditioner 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 fan 601, and is blown out from the fresh air outlet 202 by the turbulence fan 601 after passing through the ventilation section.

[0113] Optionally, the air duct switching device further includes: a second disc 607, which covers the first disc 603. The second disc 607 has a hollow section in the middle, and multiple air guiding components 602 are provided in the hollow section to guide the airflow direction generated by the turbulence fan 601.

[0114] The second disc 607 faces the user and can be fixedly installed with or rotate relative to the first disc 603. The airflow from the fresh air outlet 202 is guided by the air guide component 602, thereby guiding the direction of the airflow from the turbulence fan 601. The air guide component 602 can be understood as an air guide grille. The hollow portion of the second disc 607 can be understood as the fresh air outlet 202.

[0115] Optionally, a display screen is provided in the center of the hollowed-out portion of the second disc 607, and the air guide components 602 are arranged radially around the circumference of the display screen. Preferably, multiple air guide components 602 are arranged in a spiral direction. Figure 6 As shown.

[0116] In practical applications, the turbulence fan 601 can also be installed on the second disc 607.

[0117] Optionally, the indoor unit of the air conditioner also includes a front panel 20, and a first plate 603 is disposed on the front panel 20 and can rotate relative to the front panel 20.

[0118] The first disc 603 is located on the front panel 20 and rotates relative to the front panel 20. This not only helps the airflow from the first disc 603 to disturb the airflow from the main air outlet, but also makes it easier for the user to adjust the first disc 603 to achieve the purpose of switching the air duct.

[0119] For example, the first disc body 603 is disposed through the front panel 20 and is rotatable relative to it.

[0120] In addition, the second panel 607 is equipped with a display screen, which makes it easier for users to observe the temperature and operating mode of the air conditioner.

[0121] Combination Figures 11 to 15 As shown in the figure, this disclosure provides another air duct switching device, which includes:

[0122] The active ring 609 includes a guide section 610, which encloses a ventilation duct, and the side wall of the guide section has a ventilation opening that communicates with the ventilation duct.

[0123] The airflow guide 611 can slide relative to the airflow guide 610. One end of the airflow guide 611 is closed and its side wall is constructed with a first air outlet 6111 and a second air outlet 6112. The first air outlet 6111 and the second air outlet 6112 are staggered and are used to connect different fresh air outlets.

[0124] The movable ring 609 can slide relative to the guide portion 611 so that the vent 6101 of the guide portion can selectively communicate with the first vent 6111 and / or the second vent 6112.

[0125] Using the air duct switching device provided in this embodiment, the movable ring 609 drives the guide part to slide, that is, the guide part and the guide part 611 slide relative to each other, so that the ventilation opening 6101 of the guide part can selectively connect with the first air opening 6111 and / or the second air opening 6112. The first air opening 6111 and the second air opening 6112 are used to connect different fresh air openings, thus achieving the purpose of selective air duct switching. Through different air intake paths, not only can the range of installation locations of the indoor unit of the air conditioner be expanded, but also different air outlet needs of users can be met.

[0126] When the movable ring 609 slides, the guide portion slides with the movable ring 609, and the position of the vent changes with the movement of the guide portion. When the vent moves to the first air vent 6111, the guide portion connects to the first air vent 6111, thereby connecting to the first fresh air inlet 401 connected to the first air vent 6111. When the vent moves to the second air vent 6112, the guide portion connects to the second air vent 6112, thereby connecting to the second fresh air inlet 501 connected to the first air vent 6111. When the vent moves to a position where it is partially connected to the first air vent 6111 and partially connected to the second air vent 6112, the guide portion connects not only to the first fresh air inlet 401 but also to the second fresh air inlet 501.

[0127] 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 switch the air duct by manually pushing and pulling the movable ring 609.

[0128] Optionally, along a direction perpendicular to the front panel 20, the distance from the first air vent 6111 to the front panel 20 is less than the distance from the second air vent 6112 to the front panel 20. The first air vent 6111 is closer to the front panel 20 than the second air vent 6112. The first air vent 6111 and the second air vent 6112 are arranged one in front of the other, so that when the guide portion moves back and forth, the ventilation opening 6101 of the guide portion can selectively communicate with the first air vent 6111 and / or the second air vent 6112.

[0129] Optionally, when the movable ring 609 slides to the first position along a direction perpendicular to the front panel 20, the vent 6101 of the guide section is connected to the first air vent 6111; when the movable ring 609 slides to the second position, the air inlet of the ventilation duct of the guide section is connected to the second air vent 6112, and the vent 6101 of the guide section is connected to the first air vent 6111; when the movable ring 609 slides to the third position, the air inlet of the ventilation duct of the guide section is connected to the second air vent 6112, and the side wall of the guide section is configured to close the first air vent 6111. This achieves the purpose of selective switching of the air duct.

[0130] Optionally, the flow guide 611 is fitted onto the flow guide, and when the movable ring 609 slides inward and the vent is correspondingly set with the second air vent 6112, the flow guide and the flow guide 611 abut against each other.

[0131] When the movable ring 609 slides inward and the vent is aligned with the second air vent 6112, the guide part abuts against the guide part 611 to limit the guide part and prevent the movable ring 609 from sliding further. This reminds the user that the vent is aligned with the second air vent 6112 and the air duct switching is complete, avoiding excessive sliding that could cause the vent and the second air vent 6112 to be misaligned, thus reducing the ventilation volume.

[0132] Optionally, the ventilation area of ​​the vent 6101 in the guide section, the ventilation area of ​​the first vent 6111, and / or the ventilation area of ​​the second vent 6112 are equal. In this way, when the first vent 6111 is correspondingly arranged to the vent 6101 in the guide section, or the second vent 6112 is correspondingly arranged to the vent 6101 in the guide section, it not only helps to ensure the ventilation volume, but also prevents airflow from non-corresponding vents from flowing into the guide section.

[0133] Optionally, the first air vent 6111 is located above the second air vent 6112. In this way, the first air vent 6111 and the second air vent 6112 do not interfere with each other and each corresponds to a different fresh air inlet, thus ensuring different air intake paths.

[0134] In this embodiment, the first air vent 6111 is connected to the first fresh air inlet 401 of the housing 10, and the second air vent 6112 is connected to the second fresh air inlet 501 of the housing 10.

[0135] Optionally, the closed end of the flow guide 611 is provided with a positioning structure 6113, and the end of the conduction part is provided with a mating structure 6102. The mating structure 6102 is adapted to the positioning structure 6113 so that the flow guide 611 and the conduction part can be installed and positioned.

[0136] When the air guide 611 and the guide part are assembled, the positioning structure 6113 and the mating structure 6102 ensure that the relative positional relationship between the air guide 611 and the guide part is correct, avoiding misalignment that would cause the vent to not correspond to the first air vent 6111 or the second air vent 6112.

[0137] For example, the positioning structure 6113 and the mating structure 6102 may be a positioning groove or a positioning post, or the positioning structure 6113 and the mating structure 6102 may be a positioning notch and a positioning protrusion.

[0138] Optionally, the flow guide 611 abuts against the partition 30, and the positioning structure 6113 is adapted to the structure of the partition 30.

[0139] The flow guide 611 abuts against the partition 30, which provides support to the closed end of the flow guide 611, facilitating its installation and fixation and preventing the closed end of the flow guide 611 from shaking when the flow guide moves. Furthermore, the matching structure of the positioning structure 6113 with the partition 30 further strengthens the fixation of the flow guide 611 and improves its positioning accuracy during assembly.

[0140] Optionally, the air duct switching device of this embodiment further includes: a fixed ring 612, which is disposed on the front panel 20 of the air conditioner and has a hollowed-out center; wherein, the movable ring 609 further includes a ring body located on the air outlet side of the guide portion, the guide portion of the movable ring 609 passes through the hollowed-out area in the middle of the fixed ring 612, and the ring body of the movable ring 609 covers the outer surface of the ring body of the fixed ring 612.

[0141] The movable ring 609 is mounted on the outer surface of the fixed ring 612, and the fixed ring 612 enables its relative connection with the front panel 20. The movable ring 609 moves back and forth relative to the fixed ring 612 to change the position of the vent and achieve the purpose of switching the air duct.

[0142] Optionally, the air duct switching device further includes: a turbulence fan 601, located at the air outlet of the guide section, so that air is drawn in through the first air outlet 6111 and / or the second air outlet 6112 and blown out by the turbulence fan 601.

[0143] Air located in the indoor unit of the air conditioner flows in through the first air vent 6111 and / or the second air vent 6112 under the suction of the turbulence fan 601, and is blown out from the fresh air outlet 202 by the turbulence fan 601 through the guide section.

[0144] Optionally, the air duct switching device further includes an air guide 613, disposed at the air outlet of the guide section and located on the air outlet side of the turbulence motor. This guides the airflow blowing from the air outlet of the guide section, thereby directing the flow direction of the airflow blown by the turbulence fan 601. The air guide 613 can be understood as an air guide grille.

[0145] This disclosure also provides an indoor air conditioning unit, including: a housing 10, a partition 30, a top plate 40, and a middle plate 50, which serve to support and install the various components of the indoor air conditioning unit.

[0146] The housing 10 defines a receiving cavity; the partition 30 is disposed within the receiving cavity and divides the receiving cavity into an independent heat exchange air duct 101 and a fresh air duct; the top plate 40 is disposed at the top of the housing 10; the middle plate 50 is disposed within the housing 10 and located at the bottom of the partition 30; wherein the top plate 40 and / or the middle plate 50 are configured with a fresh air inlet communicating with the fresh air duct.

[0147] The air conditioner indoor unit using the embodiments of this disclosure has an independently set heat exchange duct 101 and a fresh air duct, with the heat exchange duct 101 and the fresh air duct each discharging air separately, which can bring different user experiences. In addition, the top plate 40 and / or the middle plate 50 are constructed with fresh air inlets that are connected to the fresh air duct. The different air intake paths can not only expand the range of installation locations for the air conditioner indoor unit, but also meet the different air outlet needs of users.

[0148] 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.

[0149] For ease of description, the fresh air vent located on the top plate 40 is defined as the first fresh air inlet 401 of the housing 10, and the fresh air vent located on the middle plate 50 is defined as the second fresh air inlet 501 of the housing 10.

[0150] The first fresh air inlet 401 and the second fresh air inlet 501 are only connected to the fresh air duct.

[0151] Optionally, if the top plate 40 is equipped with a fresh air inlet, it further includes: an air intake section 402, one end of which abuts against the top plate 40 and the other end of which abuts against the partition plate 30; and the air duct enclosed by the air intake section 402 is connected to the fresh air inlet of the top plate 40, so that the airflow flowing in from the fresh air inlet of the top plate 40 is guided to the fresh air duct through the air intake section 402.

[0152] In practical applications, for ease of assembly, there is a gap between the top of the partition 30 and the top plate 40. Therefore, when the top plate 40 is equipped with a first fresh air inlet 401, the air flowing in from the first fresh air inlet 401 will not only flow into the fresh air duct but also into the heat exchange duct 101. By providing the air duct 402, the flow path of air to the heat exchange duct 101 can be sealed off, so that all the air flowing in from the first fresh air inlet 401 of the top plate 40 flows into the fresh air duct.

[0153] One end of the air intake section 402 abuts against the top plate 40, and the other end abuts against the partition plate 30, which can improve the stability of the air intake section 402 during use and prevent displacement caused by wind force.

[0154] Optionally, if the middle plate 50 is equipped with a fresh air vent, it further includes: an air duct 502, one end of which is connected to the middle plate 50 and communicates with the fresh air vent of the middle plate 50, and the other end of which is communicated with the main air inlet 103 of the indoor air conditioning unit, so that part of the airflow from the main air inlet 103 is blown out through the fresh air duct; wherein the main air inlet 103 of the indoor air conditioning unit is communicated with the heat exchange duct 101.

[0155] The main air inlet 103 of the indoor unit of the air conditioner is connected to the heat exchange duct 101, and the air flowing in from the main air inlet 103 flows into the heat exchange duct 101. In this embodiment, through the air duct 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, thereby realizing different air intake paths for the fresh air duct.

[0156] By using the air duct 502, turbulence can be avoided before the fresh air flows into the fresh air duct, and the airflow into the heat exchange duct 101 can also be avoided.

[0157] Optionally, the housing 10 also includes: a front panel 20, which, together with the partition 30, the top panel 40 and the middle panel 50, encloses a fresh air duct;

[0158] The front panel 20 has a main air outlet and a fresh air outlet 202. The main air outlet is connected to the heat exchange duct 101, and the fresh air outlet 202 is connected to the fresh air duct.

[0159] The space between the partition 30 and the front panel 20 is a fresh air duct. The partition 30 separates the heat exchange duct 101 and the fresh air duct to prevent the airflow in the heat exchange duct 101 from mixing with the airflow in the fresh air duct, thereby affecting the temperature, flow rate and velocity of the airflow at the main air outlet and the fresh air outlet 202.

[0160] The airflow from the fresh air outlet 202 disturbs the airflow from the main air outlet, causing a "pear-shaped" airflow vortex to form near the indoor unit of the air conditioner. This not only expands the radiation range of the airflow but also helps to improve the uniformity of the indoor temperature.

[0161] Optionally, the indoor unit of the air conditioner also includes: a turbulence device disposed in the fresh air outlet 202 and the fresh air duct of the front panel 20. The turbulence device includes a turbulence fan 601 to draw air from the fresh air outlet into the fresh air duct and blow it out from the fresh air outlet 202.

[0162] The turbulence fan 601 further increases the turbulence force of the indoor airflow, accelerating the airflow back to the main air inlet 103 of the air conditioner, which is beneficial for uniform indoor temperature. In practical applications, the airflow blown out by the turbulence fan 601 reaches a certain position in the room, and is slowed down by the backflow action of the air conditioner cross-flow fan 90, and flows back to the main air outlet of the air conditioner, where it mixes with the airflow blown out from the main air outlet and participates in the indoor air circulation again.

[0163] Optionally, if both the top plate 40 and the middle plate 50 are provided with fresh air inlets, it can be understood that the shell 10 has two fresh air inlets. The turbulence device also includes: a duct switching device, which is constructed with an independent first sub-fresh air duct 6053 and a second sub-fresh air duct 6054. The first sub-fresh air duct 6053 is connected to the fresh air inlet of the top plate 40, and the second sub-fresh air duct 6054 is connected to the fresh air inlet of the middle plate 50. The duct switching device is used to switch the first sub-fresh air duct 6053 and / or the second sub-fresh air duct 6054 to be connected to the fresh air outlet 202.

[0164] The air duct switching device can not only control the opening and closing of the fresh air duct, but also select different air intake paths to meet different user needs.

[0165] Optionally, if a fresh air inlet is provided on the top plate 40 or the middle plate 50, the turbulence device further includes: a duct switching device, located within the fresh air duct, for controlling the flow of the fresh air duct. The duct switching device controls the flow of the fresh air duct, thereby controlling the airflow from the fresh air outlet 202 to meet different user needs.

[0166] This disclosure also provides a turbulence device, including: a first disc 603 and a second disc 607.

[0167] The first disc 603 has a hollow section for mounting the turbulence fan 601; the second disc 607 is rotatable relative to the first disc 603 and is located on the air outlet side of the first disc 603; the second disc 607 has a hollow section in the middle, and multiple air guide components 602 are provided in the hollow section to guide the airflow generated by the turbulence fan 601.

[0168] The turbulence device of this embodiment increases the airflow and velocity in the indoor corners through the turbulence effect of the turbulence fan 601, forming multiple airflow vortices in the room, and the airflow vortices in the indoor corners are complete and smooth; and by rotating the second plate 607 relative to the first plate 603, the air guiding direction of the air guiding component 602 is adjusted, thereby guiding the airflow direction generated by the turbulence fan 601; in cooperation with the turbulence fan 601, a "pear-shaped" airflow vortex is further strengthened or selectively formed in a specific area around the indoor unit of the air conditioner, expanding the influence range of the airflow.

[0169] In practical applications, by rotating the second plate 607 relative to it by a certain angle, the air guiding direction of the air guiding component 602 is changed, thereby forming an airflow vortex around a specific area of ​​the outdoor unit of the air conditioner, or it can be understood as turbulence of airflow in a certain direction, which helps to bring different user experience.

[0170] Optionally, the hollow portion of the second disc 607 is circular, and along the radial direction, the lengths of the multiple air guide components 602 gradually increase and then gradually decrease. The different flow areas between adjacent air guide components 602 result in different airflow rates from different air guide components 602. The simultaneous blowing of airflows from different directions and with different flow rates helps to further improve the turbulence effect.

[0171] Optionally, the air guide component 602 is arc-shaped, so that the airflow directions from the same gap are not all the same, further improving the turbulence effect; and / or, the bending directions of multiple air guide components 602 are the same, so as to avoid turbulence between the airflows blown from the hollow part of the second disc 607, which would affect the air delivery distance. That is, it ensures that at least most of the airflow blown from the hollow part of the second disc 607 can mix with the airflow blown from the independent air outlet and disturb the original flow direction of the airflow.

[0172] Optionally, some or all of the air guide components 602 may have equal spacing. Equal spacing between all air guide components 602 helps improve the aesthetics of the indoor unit, but equal spacing between some air guide components 602 can be understood as having at least two spacing dimensions, which helps to increase the turbulence effect of the turbulence device on the airflow blown out of the main air outlet.

[0173] Optionally, the annular sidewalls of the first disc 603 and / or the second disc 607 are provided with protrusions 608 for anti-slip purposes. The protrusions 608 prevent slippage when rotating the first disc 603 or the second disc 607.

[0174] Optionally, the first disc 603 and the second disc 607 are disposed on the front panel 20, and the second disc 607 covers the air outlet side of the first disc 603; wherein the first disc 603 and the second disc 607 can rotate relative to the front panel 20 respectively.

[0175] In this embodiment, the purpose of switching the fresh air duct is achieved by rotating the first disc 603, and the purpose of adjusting the direction of the turbulence is achieved by rotating the second disc 607. The two work together to not only achieve the purpose of turbulence, but also to enhance the turbulence effect in specific areas, thus meeting different user needs.

[0176] This disclosure also provides an indoor air conditioning unit, including: a housing 10, a partition 30, a middle plate 50, and a purification module 70.

[0177] The housing 10 defines a receiving cavity; the partition 30 is disposed in the receiving cavity and divides the receiving cavity into an independent heat exchange air duct 101 and a fresh air duct 102; the middle plate 50 is disposed in the housing 10 and located at the bottom of the partition 30, and the middle plate 50 is configured with a fresh air inlet; the purification module 70 is disposed corresponding to the fresh air inlet of the middle plate 50 to purify the airflow flowing into the fresh air duct 102.

[0178] The air conditioning indoor unit provided in this embodiment has an independently configured heat exchange duct 101 and fresh air duct, with separate air outlets for the heat exchange duct 101 and fresh air duct, which can provide users with different user experiences. In addition, the middle plate 50 is constructed with a fresh air inlet that is connected to the fresh air duct, and the airflow 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.

[0179] Optionally, the indoor unit of the air conditioner also includes: an air duct 502, one end of which is connected to the middle plate 50 and connected to the fresh air inlet of the middle plate 50, and the other end of which is connected to the main air inlet 103 of the indoor unit of the air conditioner, so that part of the airflow from the main air inlet 103 is blown out through the fresh air duct; wherein, the main air inlet 103 of the indoor unit of the air conditioner is connected to the heat exchange duct 101.

[0180] The main air inlet 103 of the indoor unit of the air conditioner is connected to the heat exchange duct 101, and the air flowing in from the main air inlet 103 flows into the heat exchange duct 101. In this embodiment, through the air duct 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, thereby realizing different air intake paths for the fresh air duct.

[0181] By using the exhaust duct 502, turbulence can be avoided before the fresh air flows into the fresh air duct, and the airflow into the heat exchange duct 101 can also be avoided. The exhaust duct 502 is connected to the middle plate 50, which helps to improve the stability of the exhaust duct 502 during use and prevents it from shaking or making abnormal noises due to wind.

[0182] Optionally, the purification module 70 is located inside the fresh air inlet of the middle plate 50, above the middle plate 50, or below the middle plate 50. In practical applications, the installation location of the purification module 70 can be selected according to actual needs.

[0183] Optionally, when the purification module 70 is located above or below the middle plate 50, the purification module 70 passes through the housing 10 and can be pulled out for replacement.

[0184] The pull-out design of the purification module 70 facilitates its replacement, thereby ensuring the cleanliness of the air flowing into the fresh air duct.

[0185] Optionally, when the purification module 70 is located below the middle plate 50, the air duct 502 is connected to the purification module 70 so that the air in the air duct 502 flows into the fresh air duct after being purified by the purification module 70.

[0186] For example, the purification module 70 is located between the air duct 502 and the middle plate 50, or the purification module 70 is inserted into the air duct 502 to ensure that the air in the air duct 502 flows into the fresh air duct after being purified by the purification module 70.

[0187] Optionally, the indoor unit of the air conditioner also 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 airflow entering through the autonomous air inlet 103 passes through the water washing module 80 and the purification module 70 in sequence before flowing into the heat exchange air duct 101.

[0188] The water washing module 80 washes and purifies the air flowing into the heat exchange duct 101. In conjunction with the purification module 70, it ensures the cleanliness of the airflow from the independent air outlet and the fresh air outlet 202, provided that the indoor unit of the air conditioner has a turbulence function.
