The housing includes an upper housing portion and a lower housing portion. The upper housing portion has at least three first air vents extending vertically in a circumferential direction. The lower housing portion is located below the upper housing portion and has at least three second air vents extending vertically in a circumferential direction.

[0062] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 9 This invention provides an indoor air conditioning unit, including a housing, a first air supply device 610, a second air supply device 620, and a heat exchanger 400.

[0063] The housing includes an upper housing portion and a lower housing portion. The upper housing portion is provided with at least three first air vents 110, each extending vertically, and the plurality of first air vents 110 are arranged sequentially along the circumferential direction of the housing. The lower housing portion is located below the upper housing portion and is provided with at least three second air vents 210, each extending vertically, and the plurality of second air vents 210 are arranged sequentially along the circumferential direction of the housing. There are at least three first air supply devices 610, each corresponding to a first air vent 110, and each first air supply device 610 is configured to generate at least a first airflow from a second air vent 210 to the corresponding first air vent 110. There are at least three second air supply devices 620, each corresponding to a second air vent 210, and each second air supply device 620 is configured to generate at least a second airflow from a first air vent 110 to the corresponding second air vent 210. The heat exchanger 400 is disposed inside the housing and exchanges heat with the first airflow or the second airflow. That is, the heat exchanger 400 is located in the airflow path between the first air outlet 110 and the second air outlet 210.

[0064] In this embodiment, the working principle of the indoor unit of the air conditioner is as follows: When the air conditioner is heating, the first air supply device 610 stops working, and the second air supply device 620 operates normally. External airflow flows into the indoor unit of the air conditioner through the first air outlet 110 and exchanges heat with the heat exchanger 400. The hot airflow after heat exchange with the heat exchanger 400 flows out of the indoor unit of the air conditioner through multiple second air outlets 210. Multiple second air outlets 210 are arranged circumferentially in the lower shell 200, simultaneously supplying hot airflow to the outside, achieving 360° circumferential air supply. The hot airflow flows out from the second air outlets 210 located in the lower shell 200 and moves upward, reducing the vertical temperature difference. When the air conditioner is cooling, the second air supply device 620 stops working, and the first air supply device 610 operates normally. External airflow flows into the indoor unit of the air conditioner through the second air outlets 210 and exchanges heat with the heat exchanger 400. The cold airflow after heat exchange with the heat exchanger 400 flows out of the indoor unit of the air conditioner through multiple first air outlets 110. Multiple first air vents 110 are arranged circumferentially on the upper shell 100, simultaneously delivering cold air to the outside, achieving 360° circumferential air supply. The cold air flows out from the first air vents 110 located on the upper shell 100 and moves downward, reducing the temperature difference in the vertical direction.

[0065] In this embodiment, when the air-conditioned room is heating, the first air supply device 610 stops working, and the first air outlet 110 has the function of air intake; the second air supply device 620 works normally, and the second air outlet 210 has the function of air supply. When the air-conditioned indoor unit is cooling, the first air supply device 610 works normally, and the first air outlet 110 has the function of air supply; the second air supply device 620 stops working, and the second air outlet 210 has the function of air intake. The first air outlet 110 and the second air outlet 210 are circumferentially arranged to achieve 360° circumferential air supply, solving the problem of the single air supply direction of traditional air conditioners. When the air conditioner is cooling, the first air outlet 110 supplies air, and the cold air sinks; when the air conditioner is heating, the second air outlet 210 supplies air, and the hot air rises. This reduces the temperature difference in the vertical direction, enhances the overall environmental comfort, and improves the user experience.

[0066] In some embodiments of the present invention, multiple first air vents can simultaneously supply air. The angle between any two adjacent first air vents is less than or equal to 130°, allowing the user to perceive 360° circumferential airflow from the entire air conditioner, ensuring airflow from any position within the room and enhancing user experience and comfort. Specifically, the number of multiple first air vents is greater than three, such as six or eight. The more vents, the more overlapping the airflow from adjacent first air vents becomes, achieving 360° full coverage and further improving user experience and comfort. Similarly, the angle between any two adjacent second air vents is less than or equal to 130°. Further, the number of multiple second air vents is greater than three, such as six or eight.

[0067] In some embodiments of the present invention, the heat exchanger 400 includes an air inlet space 430 extending in a vertical direction, and a heat exchange portion surrounding the air inlet space 430. The first air outlet 110 is connected to the second air outlet 210 through the air inlet space 430.

[0068] In this embodiment, when the air conditioner is heating, external airflow enters the indoor unit through the first air vent 110, flows downward through the air inlet space 430 of the heat exchanger 400, and finally exits through the second air vent 210. When the air conditioner is cooling, external airflow enters the indoor unit through the second air vent 210, flows upward through the air inlet space 430 of the heat exchanger 400, and finally exits through the first air vent 110. During the flow through the air inlet space 430, heat exchange with the heat exchanger 400 is achieved. This improves heat exchange efficiency and realizes full utilization of energy.

[0069] In some embodiments of the present invention, a filter device 500 is provided at each of the first air vents 110 and the second air vents 210. The filter device 500 has a first position for shielding and a second position for opening.

[0070] In this embodiment, when the air conditioner is heating, the filter device 500 of the first air vent 110 is in a first position, blocking the corresponding first air vent 110 that serves as an air inlet; the filter device 500 of the second air vent 210 is in a second position, so that the second air vent 210 is in a fully open state. When the air conditioner is cooling, the filter device 500 of the first air vent 110 is in a second position, so that the first air vent 110 is in a fully open state; the filter device 500 of the second air vent 210 is in a second position, blocking the corresponding second air vent 210 that serves as an air inlet.

[0071] The filter device 500 blocks the first air vent 110 or the second air vent 210, which serves as the air inlet, to prevent foreign objects from entering the indoor unit casing and affecting its operation and lifespan. The first air vent 110 or the second air vent 210 serves as the air outlet, corresponding to the filter device 500 being in the second open position to ensure efficient airflow.

[0072] In some embodiments of the present invention, the heat exchanger 400 is disposed within the upper housing portion. In this embodiment, the support for the heat exchanger 400 needs to be reasonably arranged. Further, in some embodiments of the present invention, the first air supply device 610 is located on the side of the heat exchanger 400 opposite to the air inlet space 430.

[0073] In this embodiment, external airflow flows into the air inlet space 430 enclosed by the heat exchanger 400, exchanges heat with the heat exchanger 400, and then flows out through the air outlet under the drive of the air supply device. This can reduce air supply resistance and improve heat exchange efficiency.

[0074] Of course, in some embodiments of the present invention, the heat exchanger 400 may also be disposed within the lower housing portion. This is more convenient for installation than disposing it within the upper housing portion. Furthermore, the second air supply device 620 is located on the side of the heat exchanger 400 opposite to the air inlet space 430 to reduce air resistance and improve heat exchange efficiency.

[0075] In some embodiments of the present invention, the heat exchanger 400 includes a first heat exchanger 410 and a second heat exchanger 420. The first heat exchanger 410 is disposed in the upper housing portion, and the second heat exchanger 420 is disposed in the lower housing portion. In this embodiment, both the upper housing portion and the lower housing portion are provided with heat exchangers 400, so that whether the air conditioner is cooling or heating, the external airflow entering the indoor unit of the air conditioner can exchange heat more fully.

[0076] In some embodiments of the present invention, the first air supply device 610 is located on the side of the first heat exchange section 410 away from the air inlet space 430, and the second air supply device 620 is located on the side of the second heat exchange section 420 away from the air inlet space 430.

[0077] In some embodiments of the present invention, the first air supply device 610 and the second air supply device 620 are vertically arranged cross-flow fans.

[0078] In this embodiment, a cross-flow fan with an unrestricted axial length is selected as the air supply device, which can increase the air supply distance, avoid turbulence, and make the heat exchange air flow out of the air conditioner indoor unit evenly, resulting in a better user experience.

[0079] In some embodiments of the present invention, the upper housing portion and the lower housing portion are connected by a connecting hole, the connecting hole being coaxial with the air inlet space 430, and the diameter of the connecting hole being less than or equal to 1.2 times the diameter of the air inlet space 430.

[0080] In this embodiment, the connecting hole is coaxial with the air inlet space 430, and the diameter of the connecting hole is close to the diameter of the air inlet space 430. This reduces the airflow that flows directly through the outer periphery of the heat exchanger 400, allowing the airflow to circulate through the air inlet space 430 and ensuring the heat exchange effect.

[0081] In some embodiments of the present invention, a connecting portion 300 is provided between the upper housing portion and the lower housing portion. The housing is segmented, making disassembly convenient.

[0082] In some embodiments of the present invention, the connecting part 300 is composed of a plurality of connecting seats 310 connected in sequence, each connecting seat 310 being inserted between the first heat exchange part 410 and the second heat exchange part 420, and each connecting seat 310 being used to support the first heat exchange part 410.

[0083] In this embodiment, the connecting part 300 provides support for the first heat exchange part 410 of the heat exchanger 400, making the first heat exchange part 410 firm and stable.

[0084] In some embodiments of the present invention, the upper end of the second air supply device 620 is mounted on the connecting portion 300. Each connecting seat 310 is used to fix the upper end of one second air supply device 620. The connection portion 300 makes the installation of the second air supply device 620 easier.

[0085] In some embodiments of the present invention, the motor connected to the first air supply device 610 is mounted on the connecting portion 300, and each connecting seat 310 is used to mount one motor connected to the first air supply device 610. That is, the number of connecting seats 310 is the same as the number of first air outlets 110. This simplifies the installation of the motor connected to the first air supply device 610 and ensures stable operation.

[0086] In some embodiments of the present invention, the connecting seat 310 includes a support member 311, a heat exchange part support rib 312, a protrusion 313, and a filter motor clearance groove 314. The support member 311 is used to install the motor connected to the first air supply device 610. The heat exchange part support rib 312 is disposed on the inner side of the support member 311, supports the first heat exchange part 410, and its lower end face contacts the upper end face of the second heat exchange part 420. The protrusion 313 is disposed on the outer side of the support member 311, the upper housing part is placed on the support member 311, the protrusion 313 is inserted into the inner side of the upper housing part, and contacts the inner side of the upper housing part. The filter motor clearance groove 240 is disposed on the support member 311 to provide a receiving space for the motor of the filter device 500.

[0087] In some embodiments of the present invention, connecting plates are provided on both sides of the support member 311, and a connecting structure is provided between the connecting plates and the connecting plates of the adjacent connecting seat 310. The connecting structure includes a locking hole 316 and a locking claw 315 for inserting into the locking hole 316. The locking method makes installation and disassembly simple. The connecting plates on both sides of the same support member 311 may have a locking claw 315 on one side and a locking hole 316 on the other side; alternatively, both connecting plates may have either a locking claw 315 or a locking hole 316.

[0088] In some embodiments of the present invention, the outer peripheral surface of the first heat exchange part 410 is provided with a plurality of grooves 240 extending in the vertical direction, the grooves 240 are correspondingly provided with the first air outlet 110, and part or all of the first air supply device 610 is provided in the corresponding grooves 240.

[0089] In this embodiment, the first air supply device 610 is disposed within the receiving space formed by the groove 240 and the first air outlet 110. The first air supply device 610 is partially located within the groove 240, with the protruding portion of the groove 240 facing the corresponding air outlet. This makes the overall indoor unit of the air conditioner more compact.

[0090] In some embodiments of the present invention, each second air outlet 210 and its corresponding groove 240 has an air duct body defining an air outlet, and multiple air duct bodies are spaced apart. Each air duct body has an insert plate that is inserted into a connecting portion 300. A second air supply device 620 is located inside the air duct, and a protrusion between two grooves 240 of the heat exchanger 400 is inserted into the gap between two adjacent air duct bodies.

[0091] In this embodiment, the insert plate is inserted into the connecting part 300 to ensure a stable connection between the lower housing and the connecting part 300. The second air supply device 620 is located inside the air duct, making the structure more compact.

[0092] In some embodiments of the present invention, the air duct body includes a vertically arranged first air duct wall 220 and a second air duct wall 230. The end of the first air duct wall 220 away from the air outlet is inserted into a groove 240, and the end of the second air duct wall 230 away from the air outlet contacts a protruding end near the air outlet.

[0093] In this embodiment, the first duct wall 220 functions as a volute, and the second duct wall 230 functions as a volute tongue. This arrangement causes the duct body to form a volute structure, increasing the stability of airflow.

[0094] In some embodiments of the present invention, a reinforcing rib 240 extending vertically is connected to the side of the second air duct wall 230 away from the air duct body. The reinforcing rib 240 is inserted into the connecting portion 300 and contacts the inner side of the connecting portion 300, increasing the connection stability between the lower housing portion and the connecting portion 300.

[0095] Of course, in some embodiments of the present invention, the end of the first air duct wall 220 furthest from the air outlet is inserted into the groove 240, and the end of the second air duct wall 230 furthest from the air outlet is inserted into the groove 240, with the depth to which the first air duct wall 220 is inserted into the groove 240 being greater than the depth to which the second air duct wall 230 is inserted into the groove 240. This also ensures the stability of the air supply.

[0096] In some embodiments of the present invention, the heat exchange section includes fins and connecting pipes. Further, the fins are horizontally arranged, and multiple fins are sequentially arranged along the axial direction of the heat exchanger 400. Each fin has a through hole in its center to form an air inlet space 430. The connecting pipes pass through the fins.

[0097] In this embodiment, the structure and arrangement of the fins enable all airflow to flow into the air inlet space 430, and after flowing into the gap between the fins, it will not affect the airflow on the upper and lower sides, thereby improving heat exchange performance and heat exchange efficiency.

[0098] In some embodiments of the invention, each fin has a plurality of notches on its outer edge to form a groove 240. In particular, the number of notches is at least two. For example, three, four, eight, etc., preferably an even number.

[0099] In some embodiments of the present invention, the indoor unit of the air conditioner further includes a cover plate 800, which is disposed at one end of the housing.

[0100] In some embodiments of the present invention, the top-view peripheral structure of the cover plate 800 may not be consistent with that of the housing. Of course, in some embodiments of the present invention, the top-view peripheral structure of the cover plate 800 may also be consistent with that of the housing.
