[0002] Currently, some heat exchangers used in air conditioners employ a V-shaped structure. In this type of heat exchanger, the two airflow streams converge in the middle, forming a vortex. This vortex affects the airflow volume of the air conditioner and also generates noise, impacting user comfort. Summary of the Invention

[0003] This invention provides an indoor air conditioning unit and an air conditioner that reduce the generation of eddies.

[0004] According to one aspect of the present invention, an air conditioning indoor unit is provided, comprising:

[0005] A heat exchanger includes a first heat exchange section and a second heat exchange section arranged at an angle, the first heat exchange section and the second heat exchange section blowing air towards each other; and

[0006] A flow guiding component is disposed between the first heat exchange section and the second heat exchange section to separate the airflow from the first heat exchange section and the second heat exchange section.

[0007] In some embodiments, the flow guiding component includes a first flow guiding section and a second flow guiding section located downstream of the first flow guiding section. The width of the first flow guiding section gradually increases along the first direction in the second direction, and the width of the second flow guiding section gradually decreases along the first direction in the second direction. The first direction is the direction in which the flow guiding component guides the airflow, and the second direction is perpendicular to the first direction.

[0008] In some embodiments, the length of the first guide section is greater than the length of the second guide section.

[0009] In some embodiments, the connection between the first guide section and the second guide section is a circular arc transition.

[0010] In some embodiments, the radius of the arc is 0.5 to 1.5 times the total length of the heat exchanger along the first direction.

[0011] In some embodiments, the flow guiding component further includes a third flow guiding section located upstream of and connected to the first flow guiding section, wherein the width of the third flow guiding section in the second direction gradually decreases along the first direction.

[0012] In some embodiments, the flow guiding component further includes a fourth flow guiding section located upstream of and connected to the third flow guiding section, wherein the width of the fourth flow guiding section in the second direction gradually increases along the first direction.

[0013] In some embodiments, the width of the connection between the first guide segment and the second guide segment is greater than the width of the connection between the third guide segment and the fourth guide segment.

[0014] In some embodiments, the width of the connection between the first guide segment and the second guide segment is 1 to 5 times the width of the connection between the third guide segment and the fourth guide segment.

[0015] In some embodiments, the angle between the first side of the fourth guide section near the first heat exchange section and the second side of the fourth guide section near the second heat exchange section is equal to the angle between the first heat exchange section and the second heat exchange section.

[0016] In some embodiments, the first side of the fourth flow guide section near the first heat exchange section is in contact with the third side of the first heat exchange section near the flow guide member; and / or, the second side of the fourth flow guide section near the second heat exchange section is in contact with the fourth side of the second heat exchange section near the flow guide member.

[0017] In some embodiments, the angle between the fifth side of the first guide section near the first heat exchanger and the sixth side of the first guide section near the second heat exchanger is 10° to 30°; and / or, the angle between the seventh side of the second guide section near the first heat exchanger and the eighth side of the second heat exchanger is 30° to 60°.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment of the air conditioner indoor unit provided by the present invention, the air conditioner indoor unit includes a heat exchanger 10 and a flow guiding component 20. The heat exchanger 10 includes a first heat exchange section 11 and a second heat exchange section 12 arranged at an angle, the first heat exchange section 11 and the second heat exchange section 12 blowing air toward each other, and the flow guiding component 20 is disposed between the first heat exchange section 11 and the second heat exchange section 12 to separate the airflow from the first heat exchange section 11 and the second heat exchange section 12.

[0031] By providing a flow guide 20 between the first heat exchange section 11 and the second heat exchange section 12, the airflow from the first heat exchange section 11 and the airflow from the second heat exchange section 12 can be separated, preventing the airflow from the first heat exchange section 11 and the airflow from the second heat exchange section 12 from converging and generating eddies. Reducing eddies can reduce airflow loss, reduce the impact on the airflow volume, reduce noise, and improve user comfort.

[0032] The outer contour of the airflow guide 20 is constructed as a smooth streamlined structure, which allows the airflow to flow smoothly on the outer surface of the airflow guide 20, reduces airflow disturbance, and guides the airflow to exit smoothly.

[0033] The included angle between the first heat exchange section 11 and the second heat exchange section 12 is 0° to 180°, such as 60°, 85°, 90°, 120°, etc.

[0034] The first heat exchange section 11 and the second heat exchange section 12 can be arranged in a V-shape, C-shape, M-shape or W-shape, etc.

[0035] In such Figure 1 In the embodiment shown, the first heat exchange section 11 and the second heat exchange section 12 are arranged in a V-shape, and the included angle between the first heat exchange section 11 and the second heat exchange section 12 is approximately 85°. The flow guiding member 20 is inserted into the included angle between the first heat exchange section 11 and the second heat exchange section 12, and there is a gap between the flow guiding member 20 and the first heat exchange section 11 and the second heat exchange section 12.

[0036] The airflow guiding component 20 is located in the air outlet area formed between the first heat exchange section 11 and the second heat exchange section 12. In such a case... Figure 1 In the embodiment shown, the flow guiding component 20 is located on the angle bisector of the angle formed between the first heat exchange section 11 and the second heat exchange section 12.

[0037] The indoor unit of the air conditioner also includes a housing 30, which has an air inlet and an air outlet 31. The heat exchanger 10 and the air guiding component 20 are both disposed inside the housing 30, and the housing 30 also contains electrical components 40. The outlet of the air outlet area formed between the first heat exchange section 11 and the second heat exchange section 12 faces the air outlet 31 of the housing 30.

[0038] refer to Figure 3 As shown, in some embodiments, the flow guiding component 20 includes a first flow guiding section 21 and a second flow guiding section 22 located downstream of the first flow guiding section 21. The width of the first flow guiding section 21 gradually increases in the second direction along the first direction, and the width of the second flow guiding section 22 gradually decreases in the second direction along the first direction. The first direction is the direction in which the flow guiding component 20 guides the airflow, and the second direction is perpendicular to the first direction. This arrangement provides sufficient flow space for the airflow upstream while simultaneously causing the airflow to converge towards the center downstream. Figure 4 As shown, this ensures the uniformity and stability of the airflow as it leaves the outlet area.

[0039] In such Figure 3 In the embodiment shown, the length of the first guide section 21 is L1, and the length of the second guide section 22 is L2, where L1 > L2. This arrangement increases the length of the first guide section 21, allowing the airflow to undergo a slower, slightly reversed process; at the same time, it ensures that the airflow can quickly converge towards the center downstream, guaranteeing the uniformity and stability of the airflow outward.

[0040] The length L1 of the first guide section 21 can be 1.5 to 3.5 times the length L2 of the second guide section 22, such as 1.5 times, 2 times, 2.5 times, 3 times or 3.5 times.

[0041] In some embodiments, the connection between the first guide section 21 and the second guide section 22 is made with a rounded transition. This arrangement can reduce airflow disturbance caused by airflow change and ensure the smoothness of airflow.

[0042] like Figure 1 As shown, the radius R of the arc is 0.5 to 1.5 times the total length C of the heat exchanger 10 along the first direction, such as 0.5 times, 1 time, or 1.5 times.

[0043] In some embodiments, the flow guiding component 20 further includes a third flow guiding section 23 located upstream of and connected to the first flow guiding section 21, wherein the width of the third flow guiding section 23 in the second direction gradually decreases along the first direction. This arrangement can form a recess between the third flow guiding section 23 and the first flow guiding section 21, increasing the turning radius of the airflow near the heat exchanger 10 and making the airflow smoother.

[0044] Furthermore, the flow guiding component 20 also includes a fourth flow guiding section 24 located upstream of and connected to the third flow guiding section 23, wherein the width of the fourth flow guiding section 24 in the second direction gradually increases along the first direction. By providing the fourth flow guiding section 24, the upstream end of the flow guiding component 20 can be matched with the structure in which the first heat exchange section 11 and the second heat exchange section 12 are arranged at an angle.

[0045] In some embodiments, the first side of the fourth guide section 24 near the first heat exchange section 11 is in contact with the third side of the first heat exchange section 11 near the guide member 20; and / or, the second side of the fourth guide section 24 near the second heat exchange section 12 is in contact with the fourth side of the second heat exchange section 12 near the guide member 20. This arrangement allows the guide member 20 to fit against both sides of the heat exchanger 10, reducing air leakage.

[0046] In some embodiments, the width at the junction of the first guide section 21 and the second guide section 22 is greater than the width at the junction of the third guide section 23 and the fourth guide section 24.

[0047] In some embodiments, the width of the connection between the first guide section 21 and the second guide section 22 is 1 to 5 times the width of the connection between the third guide section 23 and the fourth guide section 24, such as 1.2 times, 2 times, 3 times, 4 times or 5 times.

[0048] In some embodiments, the included angle between the first side of the fourth guide section 24 near the first heat exchange section 11 and the second side near the second heat exchange section 12 is equal to the included angle between the first heat exchange section 11 and the second heat exchange section 12. This arrangement can also match the upstream end of the guide member 20 with the structural form of the heat exchanger 10, reducing air leakage.

[0049] In some embodiments, the included angle β between the fifth side of the first guide section 21 near the first heat exchange part 11 and the sixth side of the second heat exchange part 12 is 10° to 30°, such as 10°, 15°, 20°, 25°, or 30°; and / or, the included angle α between the seventh side of the second guide section 22 near the first heat exchange part 11 and the eighth side of the second heat exchange part 12 is 30° to 60°, such as 30°, 40°, 45°, or 60°. Controlling the included angles α and β within the above ranges can make the airflow more uniform and prevent airflow disturbance.

[0050] In some embodiments, the length of the third guide section 23 is L3, and the length of the fourth guide section 24 is L4. The sum of L3 and L4 accounts for 0% to 10% of the total length L of the guide component 20, such as 0.5%, 5%, or 10%. This value range is greater than 0%. By controlling the sum of L3 and L4 within the above range, the overall guiding effect on the airflow can be maximized while ensuring that the airflow near the heat exchanger 10 has a sufficient turning radius, thus preventing the airflow from generating vortices in the outlet area.

[0051] Based on the above-described air conditioner indoor unit, the present invention also proposes an air conditioner that includes the aforementioned air conditioner indoor unit. The positive technical effects of the air conditioner indoor unit in the various embodiments described above also apply to the air conditioner, and will not be repeated here.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can still be made to some technical features without departing from the principle of the present invention, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in the present invention.
