Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] This application provides an indoor air conditioner unit to solve the problem of a small swing angle in floor-standing air conditioners. The following description will be provided in conjunction with the accompanying drawings.

[0030] In the embodiments of this application, such as Figure 1 As shown, the indoor unit of the air conditioner includes: The main body 1 is provided with an air outlet duct 11, the air outlet duct 11 having a first sidewall 111 and a second sidewall 112 disposed opposite to each other; and, The grille 2 is disposed on the main body 1 and located at the air outlet of the air outlet duct 11. The grille 2 has a first side 21 and a second side 22 disposed opposite to each other. In this configuration, the grille 2 blocks at least a portion of the air outlet duct 11, the first sidewall 111 and the first side 21 form a first airflow duct 6 at intervals, and the second sidewall 112 and the second side 22 form a second airflow duct 7 at intervals.

[0031] It should be noted that grille 2 refers to a structure used to control the direction and flow rate of airflow. In this embodiment, the indoor unit of the air conditioner refers to a floor-standing indoor unit.

[0032] Understandably, based on the air outlet of grille 2, the first airflow channel 6 and the second airflow channel 7 are used to achieve air outlet, thereby increasing the air outlet range. Furthermore, the airflow within the air outlet channel 11 is divided into three streams: left, center, and right. The airflow from grille 2 has a lower velocity, while the airflow from the left and right sides has a higher velocity. These three airflows converge at the front of grille 2, forming a thicker mixed air layer with a larger air delivery angle. Simultaneously, the airflow diffusion effect is good, making it difficult to directly blow onto any part of the user's body, creating a wraparound wind effect and enhancing comfort.

[0033] For example, when the indoor unit of the air conditioner is in the correct installation posture, the first side wall 111 and the second side wall 112 are arranged opposite each other in the horizontal direction, the first side 21 and the second side 22 are arranged opposite each other in the horizontal direction, and the first airflow channel 6 and the second airflow channel 7 are located on the left and right sides of the grille 2.

[0034] In some embodiments, such as Figure 1 As shown, the indoor unit of the air conditioner also includes an air guide assembly that is rotatably connected to the inner side of the grille 2, and the rotating shaft of the air guide assembly is set along the height direction of the air outlet.

[0035] It should be noted that the inner side of grille 2 refers to the side of grille 2 facing the air outlet duct 11. When the indoor unit of the air conditioner is in the correct installation posture, the rotation axis of the air guide assembly is set along the height direction of the air outlet, that is, along the direction of gravity. The air guide assembly refers to a structure with air guiding function, and structures with air guiding function disclosed in related technologies can be applied to this embodiment.

[0036] Understandably, the air guide assembly swings left and right to direct the airflow more concentrated to the left or right, while increasing the air delivery angle on the left and right sides and expanding the air delivery range.

[0037] In some embodiments, such as Figure 3 As shown, the air guiding assembly includes a first air guiding member 3 disposed near the first side wall 111 and a second air guiding member 4 disposed near the second side wall 112. The second side wall 112 is configured to be disposed opposite to the fan 5 of the indoor unit of the air conditioner. When the air guiding assembly is in the first air supply mode, the free end of the first air guiding member 3 forms a first air supply channel with the first side wall 111 at intervals, and the free end of the second air guiding member 4 forms a second air supply channel with the second side wall 112 at intervals. The width of the first air supply channel is A1, the width of the first air supply channel is A2, A1:A2=1:(1.1~5), or A1:A2=1:(1.5~3).

[0038] It should be noted that "the second side wall 112 is configured to be opposite to the fan 5 of the indoor unit of the air conditioner" means that the airflow generated by the cross-flow fan 5 configured in the indoor unit of the floor-standing air conditioner has a velocity gradient, that is, the airflow velocity is higher near the left side of the indoor unit and lower near the right side, or the airflow velocities are reversed on the left and right sides. The second side wall 112 refers to the side near the lower airflow velocity. Therefore, the first side wall 111 refers to the side near the higher airflow velocity.

[0039] Understandably, based on the above situation and combined with the air outlet characteristics of the cross-flow fan 5 of the indoor unit of the floor-standing air conditioner, the ratio range of A1 to A2 is designed to divide the entire airflow in the air outlet duct 11 into two streams as evenly as possible, to offset the problem of large differences in the strength of the airflow on the left and right sides caused by the difference in flow velocity, to balance the flow field distribution on the left and right sides of the grille 2, to better increase the airflow thickness, and to expand the air outlet range.

[0040] For example, the ratio of A1 to A2 can also be 1:1.1, 1:1.5, 1:2, 1:3, 1:4 or 1:5, or any range between any two of the above ratios.

[0041] In some embodiments, the grille 2 is provided with multiple soft air channels, at least some of which are connected to the first air supply channel and the second air supply channel.

[0042] Understandably, multiple soft-wind channels soften the airflow. In the first air delivery mode of the air guide assembly, some soft-wind channels are blocked by the air guide assembly. The airflow from the first and second air delivery channels can still flow out from the unblocked soft-wind channels, the first airflow channel 6, and the second airflow channel 7. The blown air not only has a comfortable feel but also creates an enveloping breeze.

[0043] In some embodiments, such as Figure 2 As shown, when the air guide assembly is in the off mode, the first air guide 3 and the second air guide 4 block at least a portion of the grille 2.

[0044] Understandably, when the air guide assembly is in the off mode, the airflow mainly flows out through the first airflow channel 6 and the second airflow channel 7 to achieve long-distance delivery.

[0045] In some embodiments, such as Figure 2 As shown, the first air guide 3 includes multiple first air guide plates 31, and the second air guide 4 includes multiple second air guide plates 41. When the multiple first air guide plates 31 and the multiple second air guide plates 41 rotate in the same direction and approach the grille 2, any two adjacent first air guide plates 31 overlap or fit together end to end, any two adjacent second air guide plates 41 overlap or fit together end to end, and two adjacent first air guides 3 and second air guides 4 overlap or fit together end to end. The multiple first air guides 3 and the multiple second air guides 4 together block at least a portion of the grille 2.

[0046] It should be noted that "overlapping" refers to partial overlap between two components. "End-to-end fitting" means that one side of the rotating connecting grille 2 of one component fits against the side of another component away from its own axis of rotation. Here, the components refer to the first air guide plate 31 and the second air guide plate 41.

[0047] In some embodiments, the first air guide 3 is provided with a plurality of first soft air holes 311, and the second air guide 4 is provided with a plurality of second soft air holes 411.

[0048] Understandably, when the air guide assembly is in the off mode, the first soft air hole 311 and the second soft air hole 411 are used to disperse the airflow, achieving a soft airflow from the grille 2. Since the first soft air hole 311 and the second soft air hole 411 are relatively small, when the air guide assembly is in the first air supply mode, the first air guide 3 and the second air guide 4 primarily guide the airflow towards the target area, making it difficult for the airflow to flow into the first soft air hole 311 and the second soft air hole 411.

[0049] For example, the first air guide 3 includes two first air guide plates 31, and the second air guide 4 includes three second air guide plates 41. When the first air guide 3 and the second air guide 4 jointly block the grille 2, the first air guide plate 31 with the largest width overlaps with another first air guide plate 31, the second air guide plate 41 adjacent to the first air guide 3 is in close contact with the first air guide plate 31 with the largest width at both ends, the second air guide plate 41 with the largest width overlaps with another second air guide plate 41, and the second air guide plate 41 closest to the second side wall 112 is in close contact with the second air guide plate 41 with the largest width at both ends.

[0050] In some embodiments, such as Figure 4 as well as Figure 5 As shown, the first air guide 3 includes a plurality of first air guide plates 31, and the second air guide 4 includes a plurality of second air guide plates 41. The width of each pair of adjacent first air guide plates 31 is different, the width of each pair of adjacent second air guide plates 41 is different, and the width of adjacent first air guide plates 31 and second air guide plates 41 is different.

[0051] It is understandable that the airflow within the air outlet duct 11 is dispersed into multiple streams by multiple first air guide plates 31 and multiple second air guide plates 41, and airflow is transported in multiple directions by controlling the rotation angle of the first air guide plates 31 and the second air guide plates 41, thereby expanding the air delivery range. The adjacent first air guide plates 31 and second air guide plates 41 with different widths balance the airflow distribution on the first air guide component 3 and the second air guide component 4, and uniformly distribute the flow field in front of the grille 2.

[0052] For example, the first air guide 3 includes two first air guide plates 31, and the second air guide 4 includes three second air guide plates 41. The width of the first air guide plate 31 located closer to the first sidewall 111 is smaller than the width of the other first air guide plate 31, and the width of the second air guide plate 41 located in the middle is larger than the width of the other two second air guide plates 41. This not only achieves different widths between adjacent components, but also increases the rotation angle of the first air guide 3 along the direction closer to the first sidewall 111 and the rotation angle of the second air guide 4 along the direction closer to the second sidewall 112.

[0053] Furthermore, such as Figure 3 As shown, when the multiple first air guide plates 31 and multiple second air guide plates 41 move away from each other and rotate, the first air guide plates 31 and the second air guide plates 41 increase the air outlet angle and further expand the air outlet range of the entire area.

[0054] At this time, when the rotation angle of the first air guide plate 31 and the second air guide plate 41 further increases, two adjacent first air guide plates 31 and second air guide plates 41 overlap or adhere to each other, thereby blocking at least a portion of the grille 2. Furthermore, the first air guide plate 31 with the maximum width is used to restrict the flow to the left side of the air conditioner indoor unit, and the second air guide plate 41 with the maximum width is used to restrict the flow to the right side of the air conditioner indoor unit, forming a left-right flow splitting phenomenon.

[0055] In some embodiments, such as Figure 4 As shown, the number of second air guide plates 41 is greater than the number of first air guide plates 31.

[0056] Understandably, based on the air outlet characteristics of the cross-flow fan 5 of the indoor unit of the floor-standing air conditioner, the number of second air guide plates 41 set near the second side wall 112 is increased, and the number of first air guide plates 31 is greater, to further balance the airflow distribution.

[0057] In some embodiments, such as Figure 7 as well as Figure 8 As shown, the first air guide includes multiple first air guide plates 31, and the second air guide 4 includes multiple second air guide plates 41. The width of the multiple first air guide plates 31 is the same as the width of the multiple second air guide plates 41.

[0058] It should be noted that the width of the first air guide plate 31 refers to the distance from the rotating end to the free end of the first air guide plate 31, and the width of the second air guide plate 41 refers to the distance from the rotating end to the free end of the second air guide plate 41.

[0059] Understandably, by setting multiple first air guide plates 31 and multiple second air guide plates 41 to the same width, the airflow size flowing towards the grille 2 is balanced, and the production difficulty is reduced, making it difficult to assemble incorrectly.

[0060] In some embodiments, such as Figure 8 as well as Figure 9 As shown, the distance between the rotating ends of every two adjacent first air guide plates 31 is equal and greater than the width of the first air guide plate 31, the distance between the rotating ends of every two adjacent second air guide plates 41 is equal and greater than the width of the second air guide plate 41, and the distance between the rotating ends of adjacent first air guide plates 31 and second air guide plates 41 is greater than the width of the second air guide plate 41.

[0061] It is understandable that when multiple first air guide plates 31 and multiple second air guide plates 41 need to block the grille 2, when rotated to block the grille 2, the multiple first air guide plates 31 and multiple second air guide plates 41 can overlap together in sequence, and have a good blocking effect on the grille 2. Then, the softening effect is achieved through the first soft air hole 311 on the first air guide plate 31 and the second soft air hole 411 on the second air guide plate 41. For example, the first air guide 3 includes two first air guide plates 31, and the second air guide 4 includes two second air guide plates 41.

[0062] Furthermore, in the two adjacent first air guide plates 31 and second air guide plates 41, the free end of the first air guide plate 31 forms a first air supply channel with a gap between it and the first side wall 111, and the free end of the second air guide plate 41 forms a second air supply channel with a gap between it and the second side wall 112. The width of the first air supply channel is A1, and the width of the second air supply channel is A2, where A1:A2 = 1:(1.1~5), or A1:A2 = 1:(1.5~3). The ratio of A1 to A2 can also be 1:1.1, 1:1.5, 1:2, 1:3, 1:4, or 1:5, or any range between any two of the above ratios.

[0063] In some embodiments, the first air guide 3 includes a first link connecting a plurality of first air guide plates 31, and the second air guide 4 includes a second link connecting a plurality of second air guide plates 41.

[0064] Understandably, the first link enables the synchronous rotation of multiple first air guide plates 31, and the second link enables the synchronous rotation of multiple second air guide plates 41. Furthermore, the first air guide 3 also includes a first motor mounted on the main body 1, which drives one of the first air guide plates 31 to rotate. The second air guide 4 also includes a second motor mounted on the main body 1, which drives one of the second air guide plates 41 to rotate.

[0065] In some embodiments, such as Figure 3 As shown, the width of the first airflow channel 6 is C1, the width of the airflow channel is C2, and the width of the grille 2 is D. C1:D=1:[2~10], C2:D=1:[2~10]; or, C1:D=1:[4~8], C2:D=1:[4~8].

[0066] It is understandable that by designing the ratio of the width of the first airflow channel 6 and the second airflow channel 7 to the width of the grille 2, the degree of airflow attenuation caused by the grille 2 can be controlled. At the same time, the thickness of the mixing layer and the air outlet range can be increased by using the first airflow channel 6 and the second airflow channel 7, and the airflow energy dissipation caused by the excessive size of the first airflow channel 6 and the second airflow channel 7 can also be reduced.

[0067] For example, C1 and C2 may be equal or unequal, but are preferably equal. The ratio of C1 to D can also be 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, or 1:10, or a range between any two of the above values. The ratio of C2 to D can also be 1:2, 1:3, 1:4, 1:5, 1:6, 1:7, 1:8, 1:9, or 1:10, or a range between any two of the above values.

[0068] In some embodiments, such as Figure 2 as well as Figure 3 As shown, the first sidewall 111 is provided with a first air guide surface 113, and the second sidewall 112 is provided with a second air guide surface 114. Both the first air guide surface 113 and the second air guide surface 114 are located close to the air outlet end of the air outlet channel 11. The first air guide surface 113 and the second air guide surface 114 are inclined about the grille 2 in a direction that moves away from each other.

[0069] It should be noted that there is an angle between the first air guide surface 113 and the grille 2 that is greater than 0 degrees and less than or equal to 90 degrees, and there is also an angle between the second air guide surface 114 and the grille 2 that is greater than 0 degrees and less than or equal to 90 degrees. Furthermore, the first air guide surface 113 and the second air guide surface 114 are far apart from each other to guide the airflow outward. When the grille 2 is a planar structure, the vertical plane containing the grille 2 is used as the reference plane. When the grille 2 is a curved structure, the vertical plane containing the line connecting the first side 21 and the second side 22 of the grille 2 is used as the reference plane. The inclination angle α between the first air guide surface 113 and the second air guide surface 114 is measured using the aforementioned reference plane.

[0070] Understandably, the tilt angles of the first air guide surface 113 and the second air guide surface 114 relative to the grille 2 are designed according to the actual product positioning. When the tilt angle is greater than 0 degrees and less than or equal to 45 degrees, the airflow from the first airflow channel 6 and the second airflow channel 7 blows directly at the user; when the tilt angle is greater than 45 degrees and less than or equal to 90 degrees, the airflow from the first airflow channel 6 and the second airflow channel 7 does not blow directly at the user.

[0071] In some embodiments, such as Figure 6 As shown, the first air guide 3 and the second air guide 4 rotate close to each other, and multiple first air guide plates 31 and multiple second air guide plates 41 are used to guide the airflow in the air outlet duct 11 to the grille 2.

[0072] It is understandable that by using the first air guide 3 and the second air guide 4 to concentrate the airflow direction and increase the air velocity, the air delivery distance can be increased to meet the user's long-distance air delivery needs.

[0073] This application also provides an air conditioner, which includes the above-mentioned indoor unit and outdoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] Example 1, such as Figure 1 As shown, multiple first air guide plates 31 and multiple second air guide plates 41 swing to an angle approximately perpendicular to the grille 2, guiding the airflow to be directed towards the front of the grille 2.
