Abstract

This utility model relates to an indoor unit of an air conditioner, which includes a casing and an air guide plate. The casing has an air outlet. The air guide plate is rotatably disposed at the air outlet. The air guide plate includes an outer air plate and an inner air plate. The outer air plate is rotatably installed at the air outlet. The inner air plates are spaced apart on the side of the outer air plate near the interior of the casing, forming an air guide channel between the inner and outer air plates. Air guide ribs are provided on the sidewall of the air guide channel, extending along the airflow direction within the channel. Multiple air guide ribs are arranged at intervals, with air guide grooves forming between adjacent ribs. These grooves extend along the airflow direction within the channel and communicate with it.

Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor unit of an air conditioner. Background Technology

[0002] Split air conditioners typically consist of an indoor unit and an outdoor unit, which are installed indoors and outdoors respectively, and connected by pipes and wires.

[0003] When the indoor unit of an air conditioner is working, it usually draws in indoor air through the air inlet, and after passing through components such as the filter, heat exchanger, fan wheel and air duct, it is sent back to the room through the air outlet.

[0004] In related air conditioner indoor units, there is usually an air guide vane at the air outlet. The vane can rotate along the air outlet to change the direction of the airflow. When the airflow is directed by the vane, the concentrated airflow causes intense friction in the vane structure, which can easily lead to relatively loud airflow noise. Utility Model Content

[0005] The purpose of this utility model is to provide an indoor unit for an air conditioner that optimizes the structure of the air guide plate, so that the air guide plate forms a softer airflow effect and reduces the noise of the air guide plate.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, an indoor unit of an air conditioner is provided, comprising: a casing forming the outer shell of the indoor unit; an air outlet on the casing; and an air guide plate rotatably disposed at the air outlet. The air guide plate includes: an outer air plate rotatably mounted at the air outlet; and an inner air plate spaced apart on the side of the outer air plate near the interior of the casing, wherein an air guide channel is formed between the inner air plate and the outer air plate. At least a portion of the airflow from the air outlet can flow through the air guide channel and exit along the outer air plate. Air guide ribs are provided on the sidewall of the air guide channel, extending along the airflow direction within the air guide channel. Multiple air guide ribs are provided, spaced apart sequentially, with air guide grooves formed between adjacent ribs, extending along the airflow direction within the air guide channel and communicating with the air guide channel.

[0008] The above technical solution has the following advantages or beneficial effects: An air guide channel is formed between the inner and outer air panels, allowing the airflow from the outlet to pass through the channel and exit along the outer air panel. Air guide ribs are installed on the sidewalls of the air guide channel, and multiple ribs work together to form multiple air guide slots. This allows the airflow from the air guide channel to be dispersed by the multiple air guide slots, preventing airflow concentration within the channel and creating a gentler airflow effect. Multiple air guide ribs and multiple air guide slots can disperse airflow pressure, which helps reduce the intense friction on the air guide plate structure caused by concentrated airflow, thereby reducing the noise of the air guide plate.

[0009] In some embodiments of this application, a plurality of the air guide ribs are arranged in parallel at intervals within the air guide channel.

[0010] The above-mentioned technical solution has the following advantages or beneficial effects: By arranging multiple air guide ribs in parallel at intervals, multiple air guide slots can be arranged in parallel, and the airflow blown out of the air guide channel can flow more smoothly along multiple air guide slots, thereby improving the air outlet efficiency of the air guide channel and forming a softer air outlet effect.

[0011] In some embodiments of this application, the inner air panel is disposed on the inner side of the outer air panel near the air outlet, and the air guide channel is formed between the outer air panel near the air outlet and the inner air panel.

[0012] The above-mentioned technical solution has the following advantages or beneficial effects: by arranging the inner air panel close to the air outlet, the air guide channel can be arranged close to the air outlet, so that the airflow blown out of the air outlet can enter the air guide channel nearby and smoothly, and be blown out through the air guide channel more smoothly, flowing into the room along the outer air panel.

[0013] In some embodiments of this application, the air guide ribs are disposed on the inner sidewall of the outer air panel.

[0014] The above-mentioned technical solution has the following advantages or beneficial effects: By setting the air guide ribs on the inner wall of the outer air panel, multiple air guide grooves can be formed on the inner wall of the outer air panel. The airflow blown out by the air guide channel can flow along the multiple air guide grooves on the inner wall of the outer air panel, dispersing the airflow pressure on the outer air panel, reducing the severe friction caused by concentrated airflow on the air guide panel structure, and thus reducing the noise of the air guide panel. In addition, in the direction of airflow, the inner air panel is shorter than the outer air panel. If the air guide ribs are set on the inner air panel, the air guiding effect is not obvious, and the effect of dispersing airflow pressure is poor.

[0015] In some embodiments of this application, the first end of the air guide rib extends to the side of the outer air panel near the air outlet, and the second end of the air guide rib extends out of the air guide channel and extends toward the side of the outer air panel away from the air outlet.

[0016] The above-mentioned technical solution has the following advantages or beneficial effects: After the airflow blown out of the air outlet enters the air guide channel, it can smoothly enter the air guide groove from the first end of the air guide rib, and flow in the air guide groove along the extension direction of the air guide rib until it is discharged from the second end of the air guide rib, and is smoothly blown out from the side of the outer air panel away from the air outlet.

[0017] In some embodiments of this application, the inner air plate is arranged in an arc shape protruding from the side facing the air guide channel, so that the width of the air guide channel gradually decreases and then gradually increases along the airflow outward direction.

[0018] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the arc protrusion of the inner air panel, when the airflow blown out of the air outlet flows through the air guide channel, it can force the air pressure in the air guide channel to increase and the airflow velocity to increase, thereby increasing the wind speed at the air outlet, increasing the penetration of the air outlet, and helping to break the indoor air stratification.

[0019] In some embodiments of this application, along the airflow outflow direction, the inner air panel sequentially includes a first arc segment and a second arc segment; along the airflow outflow direction, the distance between the first arc segment and the outer air panel gradually decreases; and along the airflow outflow direction, the distance between the second arc segment and the outer air panel gradually increases.

[0020] The above technical solution has the following advantages or beneficial effects: by cooperating with the first arc segment and the second arc segment, the distance between the connection point of the first arc segment and the second arc segment and the outer wind panel is minimized. Along the airflow outward direction, the width of the air guide channel gradually decreases and then gradually increases, thereby forcing the airflow pressure and airflow velocity in the air guide channel to increase.

[0021] In some embodiments of this application, a compression portion is formed between the first arc segment and the second arc segment, and the compression portion has a circular arc transition.

[0022] The above technical solution has the following advantages or beneficial effects: the distance between the extrusion part and the outer air panel is minimized, and the extrusion part has an arc transition structure, which allows the airflow to flow more smoothly through the air guide channel, which is conducive to improving the airflow velocity in the air guide channel.

[0023] In some embodiments of this application, the air guide plate includes: a connecting plate disposed between the inner air plate and the outer air plate; one end of the connecting plate is connected to the inner air plate and the other end is connected to the outer air plate; at least two connecting plates are provided, and the at least two connecting plates are respectively disposed at both ends of the inner air plate in the length direction; the air guide channel is formed between the inner air plate, the outer air plate and the two connecting plates.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: By placing a connecting plate between the inner and outer air panels, the inner air panel can be fixed to the inner side of the outer air panel through the connecting plate. By placing at least two connecting plates at both ends of the inner air panel along its length, the air guiding channel can be formed between the inner air panel, the outer air panel, and the two connecting plates, which can improve the overall structural strength of the air guiding panel and form a stable air guiding channel between the inner and outer air panels.

[0025] In some embodiments of this application, the air guide plate includes: a partition plate disposed between the inner air plate and the outer air plate, and disposed within the air guide channel; multiple partition plates are provided, and the multiple partition plates divide the air guide channel to form multiple air guide units; multiple air guide ribs are respectively provided on the inner wall of the air guide unit.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: the partition plate can improve the connection stability between the inner and outer air panels and improve the overall structural strength of the air guide plate. The airflow blown out of the air outlet can enter different air guide units in the air guide channel, and then be blown into the room along the outer air panel. Attached Figure Description

[0044] Figure 1 This is a structural diagram of the indoor unit of an air conditioner according to some embodiments of this utility model. Figure 2 yes Figure 1 Structure diagram in another state.

[0045] like Figure 1 and Figure 2 As shown, some embodiments of this application provide an indoor unit for an air conditioner, which may include a housing 1. The housing 1 may be configured as an outer casing for the indoor unit. The interior of the housing 1 may be used to provide installation space.

[0046] In some embodiments, the casing 1 may adopt a hollow cuboid structure. The length direction of the casing 1 may be arranged horizontally, so that the indoor unit of the air conditioner is arranged laterally in the usage site, thereby reducing the height of the indoor unit and reducing the space occupied by the indoor unit.

[0047] It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed, and no limitation is made here.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the indoor unit of the air conditioner may include an indoor heat exchanger (not shown in the figure), which is disposed inside the casing 1. The indoor heat exchanger can serve as both a condenser and an evaporator, allowing the refrigerant to absorb heat by evaporating in the evaporator and release heat by condensing in the condenser, thereby enabling the air conditioner indoor unit to perform a cooling cycle or a heating cycle.

[0049] Specifically, in the refrigeration cycle, the indoor heat exchanger can act as an evaporator. In the heating cycle, the indoor heat exchanger can act as a condenser.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the indoor unit of the air conditioner may include an indoor fan assembly (not shown). The indoor fan assembly may be arranged opposite to the indoor heat exchanger. The indoor fan assembly can be used to introduce indoor air into the casing 1 for heat exchange with the indoor heat exchanger, forming a heat exchange airflow.

[0051] For example, during the refrigeration cycle, the indoor heat exchanger acts as an evaporator. The indoor fan assembly can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger to exchange heat with it, thereby reducing the temperature of the air flowing through the indoor heat exchanger. The cooled air is then blown back into the room to lower the indoor air temperature.

[0052] For example, during the heating cycle, the indoor heat exchanger acts as a condenser, and the outdoor fan assembly can draw indoor air from outside the casing 1 and blow it towards the indoor heat exchanger to exchange heat with it, raising the temperature of the air flowing through the indoor heat exchanger, and then blowing the heated air back into the room to raise the indoor air temperature.

[0053] like Figure 2 As shown, in some embodiments, an air inlet 11 may be provided on the outer wall of the housing 1. The air inlet 11 may connect to the outside of the housing 1. The air inlet 11 may connect to the indoor space. The air inlet 11 may be arranged opposite to the air inlet end of the indoor heat exchanger and the indoor fan assembly. In this way, when the indoor fan assembly is running, the indoor fan assembly can draw indoor air into the housing 1 through the air inlet 11 to exchange heat with the indoor heat exchanger, and the heat-exchanged air is discharged back into the indoor space outside the housing 1 through the air outlet end of the indoor fan assembly.

[0054] like Figure 2 As shown, in some embodiments, the air inlet 11 can be located on the top wall of the housing 1. It should be noted that in other embodiments, the air inlet 11 can also be located in other areas of the outer wall of the housing 1.

[0055] like Figure 2 As shown, in some embodiments, an air outlet 12 may be provided on the outer wall of the housing 1. The air outlet 12 may connect to the outside of the housing 1. The air outlet 12 may connect to the indoor space. The air outlet 12 may be arranged opposite to the air outlet end of the indoor fan assembly. Thus, when the indoor fan assembly is running, the indoor fan assembly draws indoor air through the indoor air inlet 11, exchanges heat with the indoor heat exchanger, and then discharges it through the air outlet end and air outlet 12 of the indoor fan assembly, and discharges it back into the indoor space outside the housing 1.

[0056] Figure 3 yes Figure 2 Structural diagram of the middle air guide plate 2.

[0057] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a guide vane 2 may be provided on the outer wall of the housing 1. The guide vane 2 is rotatably disposed at the air outlet 12. When the guide vane 2 rotates, it can open or close the air outlet 12. When the guide vane 2 rotates to open the air outlet 12, it can also change the air outlet direction of the air outlet 12.

[0058] In some embodiments, the air outlet 12 is an elongated hole, and the air outlet 12 can be arranged to extend along the length direction of the housing 1. The air guide plate 2 can be an elongated structure, and the air guide plate 2 can be arranged to extend along the length direction of the air outlet 12.

[0059] Figure 4 yes Figure 3 Front view. Figure 5 yes Figure 4 Enlarged structural diagram of region A in the middle.

[0060] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the air guide plate 2 may include an outer air plate 21, which is rotatably mounted at the air outlet 12. Rotation of the outer air plate 21 can open or close the air outlet 12. The outer air plate 21 can rotate outwards from the housing 1, thereby opening the air outlet 12. When the outer air plate 21 opens the air outlet 12, it can also change the airflow direction of the air outlet 12.

[0061] like Figure 2 and Figure 3 As shown, in some embodiments, the external air panel 21 can be a long strip-shaped plate structure. The external air panel 21 can extend along the length direction of the air outlet 12.

[0062] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the air guide plate 2 may include an inner air guide plate 22. The inner air guide plate 22 is spaced apart on the side of the outer air guide plate 21 near the interior of the housing 1. The inner air guide plate 22 can rotate with the outer air guide plate 21. When the outer air guide plate 21 closes the air outlet 12, the inner air guide plate 22 can be located inside the housing 1. When the outer air guide plate 21 opens the air outlet 12, the inner air guide plate 22 can be spaced apart on the side of the outer air guide plate 21 near the air outlet 12.

[0063] Figure 6 yes Figure 3 Enlarged structural diagram of region B in the middle.

[0064] like Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, an air guide channel 20 may be formed between the inner air panel 22 and the outer air panel 21. When the air guide panel 2 opens the air outlet 12, one side of the air guide channel 20 is arranged facing the air outlet 12 and the interior of the housing 1, and the other side of the air guide channel 20 is arranged facing the exterior of the housing 1. At least part of the airflow blown out of the air outlet 12 can flow through the air guide channel 20 and flow out into the indoor environment along the outer air panel 21. When the outer air panel 21 changes the air outlet 12's airflow direction, the airflow blown out of the air guide channel 20 can flow more smoothly into the room along the outer air panel 21.

[0065] In some embodiments, the inner air panel 22 is disposed on the inner side of the outer air panel 21 near the air outlet 12, so that the air guide channel 20 is formed between the outer air panel 21 near the air outlet 12 and the inner air panel 22. By arranging the inner air panel 22 close to the air outlet 12, the air guide channel 20 can be arranged close to the air outlet 12, so that the airflow blown out of the air outlet 12 can enter the air guide channel 20 nearby and smoothly, and be blown out more smoothly through the air guide channel 20, flowing into the room along the outer air panel 21.

[0066] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the air guide plate 2 may include a connecting plate 23, which is disposed between the inner air guide plate 22 and the outer air guide plate 21. One end of the connecting plate 23 is connected to the inner air guide plate 22, and the other end of the connecting plate 23 is connected to the outer air guide plate 21. The inner air guide plate 22 can be fixed to the inner side of the outer air guide plate 21 by the connecting plate 23.

[0067] Figure 7 yes Figure 3 A magnified structural diagram of region C in the middle.

[0068] like Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, at least two connecting plates 23 are provided, with the at least two connecting plates 23 respectively located at both ends of the inner air panel 22 along its length. An air guide channel 20 is formed between the inner air panel 22, the outer air panel 21, and the two connecting plates 23. By using the connecting plates 23 between the inner air panel 22 and the outer air panel 21, the inner air panel 22 can be fixed to the inner side of the outer air panel 21 via the connecting plates 23. By using at least two connecting plates 23 at both ends of the inner air panel 22 along its length, the air guide channel 20 can be formed enclosed between the inner air panel 22, the outer air panel 21, and the two connecting plates 23, which can both improve the overall structural strength of the air guide panel 2 and form a stable air guide channel 20 between the inner air panel 22 and the outer air panel 21.

[0069] In some embodiments, the connecting plate 23 may be located at the end of the inner air plate 22. At least one connecting plate 23 may have a rotating shaft portion 231 protruding from the side away from the other connecting plate 23, allowing the air guide plate 2 to be rotatably connected to the air outlet 12 via the rotating shaft portion 231. The rotating shaft portion 231 may be located on the outer side of the end of the inner air plate 22. Through the cooperation of the connecting plate 23 and the rotating shaft portion 231, the rotating shaft portion 231 can be rotatably connected to the inner wall of the air outlet 12, allowing the outer air plate 21 to rotate relative to the air outlet 12 about the rotating shaft portion 231 as an axis, and driving the inner air plate 22 to rotate synchronously. Furthermore, the rotating shaft portion 231 being located on the connecting plate 23 facilitates the adjustment of the center of gravity of the air guide plate 2, bringing it closer to the axis of the rotating shaft portion 231, thereby improving the rotational stability of the air guide plate 2.

[0070] In some embodiments, multiple rotating shaft portions 231 may be provided, and the multiple rotating shaft portions 231 may be respectively provided on different connecting plates 23. The multiple rotating shaft portions 231 may be arranged coaxially at intervals. The multiple rotating shaft portions 231 may be rotatably connected to the inner wall of the air outlet 12, thereby improving the overall rotational stability of the air guide plate 2.

[0071] Figure 8 yes Figure 3 A magnified structural diagram of region D in the middle.

[0072] like Figure 3 and Figure 8 As shown, in some embodiments, the connecting plate 23 can be located at the end of the outer air panel 21. A connecting hole 232 can be provided on the connecting plate 23 at the end of the outer air panel 21. A drive motor (not shown in the figure) can be provided inside the housing 1. The output end of the drive motor can be connected to the connecting hole 232, so that the drive motor is connected to the air guide plate 2 for transmission, thereby enabling the drive motor to drive the air guide plate 2 to rotate at the air outlet 12.

[0073] like Figure 5 and Figure 6 As shown, in some embodiments, the air guide plate 2 may include a partition plate 24, which is disposed between the inner air plate 22 and the outer air plate 21, and is located within the air guide channel 20. The partition plate 24 can be used to divide the air guide channel 20, so that an air guide unit 200 is formed on each of the opposite sides of the partition plate 24. Multiple partition plates 24 may be provided, and multiple partition plates 24 may be arranged sequentially at intervals along the length direction of the outer air plate 21 or the inner air plate 22. Multiple partition plates 24 can divide the air guide channel 20 into multiple air guide units 200. The partition plate 24 can improve the connection stability between the inner air plate 22 and the outer air plate 21, and improve the overall structural strength of the air guide plate 2. The airflow blown out of the air outlet 12 can enter different air guide units 200 in the air guide channel 20, and then be blown out into the room along the outer air plate 21.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments, the inner air panel 22 can extend along the length direction of the outer air panel 21. The inner air panel 22 can extend along the length direction of the air outlet 12, thereby causing the air guide channel 20 to extend along the length directions of the outer air panel 21 and the air outlet 12.

[0075] like Figure 3 and Figure 7 As shown, in some embodiments, multiple inner air panels 22 can be provided, and these multiple inner air panels 22 can be arranged sequentially at intervals along the length direction of the outer air panel 21. Multiple inner air panels 22 can form multiple air guide channels 20 with the outer air panel 21, so that the multiple air guide channels 20 are arranged sequentially at intervals along the length direction of the outer air panel 21, and further arranged sequentially at intervals along the length direction of the air outlet 12. The airflow blown out of the air outlet 12 can enter different air guide channels 20 respectively, and then be blown out into the room along the outer air panel 21.

[0076] Figure 9 yes Figure 2 A magnified structural diagram of region E in the middle.

[0077] like Figure 3 , Figure 7 and Figure 9 As shown, in some embodiments, a gap 220 is formed between adjacent inner air panels 22, and the gap 220 is formed between two connecting plates 23 at corresponding ends of two adjacent inner air panels 22. A connecting arm 13 is provided at the air outlet 12, which can extend into the gap 220 and be rotatably connected to the connecting plate 23. By having the connecting arm 13 extend into the gap 220 and be rotatably connected to the connecting plate 23, the air guide plate 2 can be more stably rotatably connected to the air outlet 12, which is beneficial to improving the structural stability and rotational stability of the air guide plate 2.

[0078] like Figure 9 As shown, in some embodiments, the connecting arm 13 can be disposed on the top sidewall of the air outlet 12. The connecting arm 13 can extend vertically, with its upper end connected to the top sidewall of the air outlet 12 and its lower end extending downward within the partition area 220. A pivot portion 231 can be provided on the connecting plate 23 on one side of the partition area 220, and the lower end of the connecting arm 13 can extend into the partition area 220 and be rotatably connected to the corresponding pivot portion 231. The partition area 220 can provide installation space and movement space for the connecting arm 13 and the corresponding pivot portion 231. In addition, part of the airflow blown out of the air outlet 12 can also enter the partition area 220 and be blown into the room along the outer air panel 21.

[0079] like Figure 9As shown, in some embodiments, the lower end of the connecting arm 13 is provided with a shaft hole 131, which is used for the insertion of the rotating shaft part 231. The rotating shaft part 231 is rotatably connected to the shaft hole 131, so that the rotating shaft part 231 can rotate about the axis of the shaft hole 131.

[0080] like Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, the side of the inner air panel 22 away from the outer air panel 21 can form an air outlet zone 210. Part of the airflow blown out of the air outlet 12 can flow through the air outlet zone 210 and then into the indoor space.

[0081] like Figure 3 and Figure 6 As shown, in some embodiments, air guide ribs 25 may be provided on the sidewall of the air guide channel 20. The air guide ribs 25 can extend along the airflow direction within the air guide channel 20. Multiple air guide ribs 25 may be provided, arranged sequentially at intervals. An air guide groove 251 is formed between adjacent air guide ribs 25. The air guide groove 251 extends along the airflow direction within the air guide channel 20 and communicates with the air guide channel 20. By setting the air guide ribs 25 on the sidewall of the air guide channel 20, multiple air guide ribs 25 cooperate to form multiple air guide grooves 251, allowing the airflow blown out of the air guide channel 20 to be dispersed by the multiple air guide grooves 251, preventing airflow concentration within the air guide channel 20 and creating a gentler airflow effect. Multiple air guide ribs 25 and multiple air guide grooves 251 can disperse airflow pressure, which helps reduce the severe friction caused by concentrated airflow on the air guide plate 2 structure, thereby reducing the noise of the air guide plate 2.

[0082] like Figure 5 and Figure 6 As shown, in some embodiments, multiple air guide ribs 25 can be arranged in parallel at intervals within the air guide channel 20. By arranging multiple air guide ribs 25 in parallel at intervals, multiple air guide slots 251 can be arranged in parallel, allowing the airflow from the air guide channel 20 to flow more smoothly along the multiple air guide slots 251, improving the air outlet efficiency of the air guide channel 20 and creating a softer air outlet effect.

[0083] In some embodiments, a plurality of air guide ribs 25 are provided on the inner wall of the air guide unit 200. The plurality of air guide ribs 25 can be arranged in parallel at intervals within the air guide unit 200.

[0084] Figure 10 yes Figure 3 Top view. Figure 11 yes Figure 10 Cross-sectional view of the structure along the FF direction.

[0085] like Figure 3 , Figure 6 and Figure 11As shown, in some embodiments, the air guide ribs 25 can be disposed on the inner sidewall of the outer air panel 21. By disposing the air guide ribs 25 on the inner sidewall of the outer air panel 21, multiple air guide grooves 251 can be formed on the inner sidewall of the outer air panel 21. The airflow blown out by the air guide channel 20 can flow along the multiple air guide grooves 251 on the inner sidewall of the outer air panel 21, dispersing the airflow pressure on the outer air panel 21, reducing the severe friction of the air guide panel 2 structure caused by concentrated airflow, and thus reducing the noise of the air guide panel 2.

[0086] It should be noted that in some other embodiments, the air guide ribs 25 may be disposed on the side wall of the inner air panel 22 facing the outer air panel 21. In the direction of airflow, since the length of the inner air panel 22 is less than that of the outer air panel 21, if the air guide ribs 25 are disposed on the side wall of the inner air panel 22, the air guiding effect will be insignificant and the effect of dispersing airflow pressure will be poor.

[0087] like Figure 11 As shown, in some embodiments, the first end 25a of the air guide rib 25 extends to the side of the outer air panel 21 near the air outlet 12, and the second end 25b of the air guide rib 25 extends out of the air guide channel 20 and extends towards the side of the outer air panel 21 away from the air outlet 12. In this way, after the airflow blown out of the air outlet 12 enters the air guide channel 20, it can smoothly enter the air guide groove 251 from the first end 25a of the air guide rib 25, and flow in the air guide groove 251 along the extending direction of the air guide rib 25 until the second end 25b of the air guide rib 25 is discharged, and smoothly blown out from the side of the outer air panel 21 away from the air outlet 12.

[0088] like Figure 6 and Figure 11 As shown, in some embodiments, there is a gap between the first end 25a of the air guide rib 25 and the side edge of the outer air panel 21 near the air outlet 12. That is, there is a gap between the first end 25a of the air guide rib 25 and the inner edge of the outer air panel 21, which can prevent the air guide rib 25 from obstructing the airflow blown out of the air outlet 12 from entering the air guide channel 20.

[0089] like Figure 6 and Figure 11 As shown, in some embodiments, there is a gap between the second end 25b of the air guide rib 25 and the side edge of the outer air panel 21 away from the air outlet 12. That is, there is a gap between the second end 25b of the air guide rib 25 and the outer edge of the outer air panel 21, so that the air flowing out of each air guide groove 251 can re-converge at the outer edge of the outer air panel 21, so that the air blown out from the outer edge of the outer air panel 21 forms a softer air outlet effect, which can further reduce the noise of the air guide 2.

[0090] Figure 12 yes Figure 11 Structural diagrams in other embodiments.

[0091] like Figure 12 As shown, in some embodiments, the air guide ribs 25 may not be provided on the side wall of the air guide channel 20.

[0092] like Figure 6 and Figure 11 As shown, in some embodiments, the inner air panel 22 is arc-shaped and protrudes towards the air guide channel 20, so that the width of the air guide channel 20 gradually decreases and then gradually increases along the airflow direction. The arc-shaped protrusion of the inner air panel 22 forces the airflow pressure and velocity within the air guide channel 20 to increase when the airflow from the air outlet 12 passes through it. This increases the wind speed at the air outlet 12, enhances the penetration of the airflow, and helps break up indoor air stratification.

[0093] like Figure 6 and Figure 11 As shown, in some embodiments, along the airflow outflow direction, the inner air panel 22 includes a first arc segment 221 and a second arc segment 222 connected in sequence. Along the airflow outflow direction, the distance between the first arc segment 221 and the outer air panel 21 gradually decreases, while the distance between the second arc segment 222 and the outer air panel 21 gradually increases. Through the cooperation of the first arc segment 221 and the second arc segment 222, the distance between the connection point of the first arc segment 221 and the second arc segment 222 and the outer air panel 21 is minimized. Along the airflow outflow direction, the width of the air guide channel 20 first gradually decreases and then gradually increases, thereby forcing an increase in airflow pressure and velocity within the air guide channel 20. Furthermore, by gradually increasing the width of the air guide channel 20 corresponding to the second arc segment 222, the airflow outlet range of the air guide channel 20 can be gradually increased, preventing all the air blown out of the air guide channel 20 from being squeezed onto the sidewall of the outer air panel 21, thereby gradually increasing the airflow outlet range of the outer air panel 21.

[0094] In some embodiments, a compression section 223 is formed between the first arc segment 221 and the second arc segment 222, and the compression section 223 has a rounded transition. The distance between the compression section 223 and the outer air panel 21 is minimal. The rounded transition structure of the compression section 223 allows the airflow to flow more smoothly through the air guide channel 20, which is beneficial to increasing the airflow velocity in the air guide channel 20.

[0095] like Figure 11 and Figure 12As shown, in some embodiments, a relief groove 224 is recessed on the side of the inner air panel 22 away from the outer air panel 21. The relief groove 224 and the air guide channel 20 are respectively disposed on opposite sides of the inner air panel 22. By forming the relief groove 224 on the side of the inner air panel 22 away from the outer air panel 21, the structure of the inner air panel 22 can be simplified, which is conducive to the flow of some airflow from the air outlet 12 through the space area on the side of the inner air panel 22 away from the outer air panel 21, and avoids the relief groove 224 obstructing the airflow on the side of the inner air panel 22 away from the outer air panel 21.

[0096] like Figure 6 , Figure 11 and Figure 12 As shown, in some embodiments, the width of the connecting plate 23 can be greater than the width of the partition plate 24 along the airflow outward direction. The wider connecting plate 23 can make the airflow within the air guide channel 20 more stable.
