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.

[0035] In this application, Figure 2 as well as Figure 6 The actual internal structure of the air conditioner indoor unit is not shown, and this does not mean that the internal structure of the air conditioner indoor unit mentioned in this application is as described. Figure 2 as well as Figure 6 As shown in the corresponding position in the middle.

[0036] This application provides an air guide structure to solve the problem of limited air delivery range of air guide plate structures. The following description will be provided in conjunction with the accompanying drawings.

[0037] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the air guiding structure includes:

[0038] The first air guide plate 1 is movably connected to the main body 4 of the air conditioner; and,

[0039] The second air guide plate 2 is slidably connected to the first air guide plate 1;

[0040] The first air guide plate 1 and the second air guide plate 2 form a guide channel 3 with openings at both ends, and the air outlet direction of the guide channel 3 is consistent with the air supply direction of the air conditioner.

[0041] It should be noted that in this embodiment, "movable connection" includes, but is not limited to, sliding connection, rotational connection, or a combination of the above connection methods. "A guide channel 3 with at least two openings" means that the guide channel 3 has two openings for airflow entry and exit; simultaneously, the air outlet direction of the guide channel 3 is consistent with the air supply direction of the air conditioner, allowing the airflow from the air conditioner to flow smoothly through the guide channel 3. The second air guide plate 2 can be slidably connected to the windward or leeward side of the first air guide plate 1. The windward side refers to the side of the first air guide plate 1 used for guiding air or facing the air outlet of the air conditioner unit 4, while the leeward side is the side opposite to the windward side. In this application, the above-mentioned air guiding structure is mainly applied to the indoor unit of a wall-mounted air conditioner.

[0042] Understandably, when airflow passes through guide channel 3, the gas molecules are constrained due to the narrow tube effect, leading to an increase in airflow velocity. This results in a higher velocity of the airflow exiting guide channel 3 compared to the surface airflow passing through the first guide plate 1 and the second guide plate 2. When the first guide plate 1 and the second guide plate 2 are positioned relatively horizontally, the high-speed airflow lifts the low-speed airflow above them, causing it to rise, while the high-speed airflow accelerates the low-speed airflow below them, transporting it over greater distances. In practical applications, this is highly suitable for guiding and transporting cold air, delaying its settling time, and enabling long-distance transport.

[0043] For example, the second air guide plate 2 can slide along the air outlet direction of the air guide channel 3. When the second air guide plate 2 slides along the direction closer to the air conditioner unit body 4, the air guiding length of the air guide structure along the air outlet direction of the air guide channel 3 increases, achieving long-distance air delivery. The second air guide plate 2 can slide along the direction away from the air conditioner unit body 4. Then the first air guide plate 1 and the second air guide plate 2 can be flipped to an approximately vertical state. The slidingly extended second air guide plate 2 can prevent the airflow from spraying upwards when it flows out of the air conditioner outlet, guiding the airflow downwards, which is suitable for carpet-like air delivery of hot air. After the second air guide plate 2 slides along the direction away from the air conditioner unit body 4, the first air guide plate 1 and the second air guide plate 2 can also be flipped to an inclined state. The first air guide plate 1 and the second air guide plate 2 guide the airflow to low and high places, avoiding the airflow blowing directly on the user.

[0044] The second air guide plate 2 can also slide in a direction perpendicular to the air outlet direction of the guide channel 3. The air guide width of the air guide structure increases in the direction perpendicular to the air outlet direction of the guide channel 3, which has the effect of guiding the airflow that is dissipating to both sides upward. Furthermore, in this example, two second air guide plates 2 can be provided to correspond to the left and right sides in the width direction of the first air guide plate 1.

[0045] In some embodiments, such as Figure 1 As shown, the two ends of the first air guide plate 1 along the first direction are rotatably connected to the main body 4 of the air conditioner. The first air guide plate 1 is provided with a sliding groove extending along the second direction, and there is an angle between the first direction and the second direction. The second air guide plate 2 includes a second sliding part and a second air guide part connected to each other, and the second sliding part is slidably connected in the sliding groove.

[0046] It should be noted that the angle between the first direction and the second direction is greater than 0° and less than 180°, and can be selected between 0° and 90°, with the first direction being perpendicular to the second direction. The first direction is the direction perpendicular to the air conditioner's air supply direction.

[0047] It is understandable that, along the first direction and / or the air conditioning outlet direction, the second air guide plate 2 can increase the air guiding area of ​​the air guiding structure by sliding.

[0048] Specifically, the first direction is perpendicular to the second direction, and the windward side of the first air guide plate 1 is provided with a groove. When the air guide structure closes the air outlet on the main body 4, the first air guide plate 1 can block the second air guide plate 2, making the appearance of the air conditioner more beautiful.

[0049] In some embodiments, such as Figure 1 As shown, the first air guide plate 1 includes a first air guide section 11 and two first connecting sections 12. The two first connecting sections 12 are connected to both ends of the first air guide section 11 along a first direction, and at least one first connecting section 12 is provided with a groove on the side facing the other connecting section.

[0050] It is understood that, along the first direction, one end of the second air guide plate 2 is slidably connected to the groove, so that the guide channel 3 formed between the second air guide plate 2 and the first air guide part 11 has at least two openings arranged along the second direction; along the first direction, the other end of the second air guide plate 2 may slide against another first connecting part 12, or may be spaced apart from another first connecting part 12, and the second air guide plate 2 is limited and supported only by the groove.

[0051] Furthermore, each of the first connecting parts 12 is provided with a groove on the side facing the other first connecting part 12, and the two ends of the second air guide plate 2 are slidably connected to the two grooves respectively along the first direction. The sidewalls of the two grooves together support and limit the second air guide plate 2.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the side wall of the guide channel 3 is provided with guide ribs 111, which extend along the air outlet direction of the guide channel 3.

[0053] It should be noted that the sidewall of the guide channel 3 includes: the surface of the first air guide 11 facing the second air guide plate 2, the surface of the second air guide plate 2 facing the first air guide 11, and the surface of the first connecting part 12 facing the second air guide plate 2. The guide ribs 111 can be provided on one or more of the above surfaces.

[0054] Understandably, along the first direction, the guide ribs 111 divide the guide channel 3 into multiple guide sub-channels 31, which can further accelerate the airflow.

[0055] Furthermore, the first air guide section 11 is provided with a plurality of air guide ribs 111 on the side facing the second air guide plate 2. The plurality of air guide ribs 111 are spaced apart along the first direction. The surface of the air guide ribs 111 facing the second air guide plate 2 can be spaced apart from the second air guide plate 2, or can slide against the second air guide plate 2.

[0056] Furthermore, along the air outlet direction of the guide channel 3, the guide ribs 111 gradually become larger, and the surface of the guide ribs 111 is smoothly rounded.

[0057] In some embodiments, the first air guide 11 is provided with a plurality of first air guide holes, and the second air guide is provided with a plurality of second air guide holes.

[0058] It should be noted that the size and shape of the multiple first air guide holes can be the same or different, the size and shape of the multiple second air guide holes can be the same or different, and the size and shape of the first air guide holes and the second air guide holes can be the same or different.

[0059] Understandably, the opening diameters of the first and second air guide holes are relatively small. This means that, while minimizing airflow loss within the guide channel 3, the opening diameters of the first and second air guide holes are designed to be small. When the first air guide plate 1 and the second air guide plate 2 are tilted, compared to a guide structure without these holes, the airflow is directed towards the user more quickly, providing a gentler breeze. Furthermore, when the first air guide plate 1 and the second air guide plate 2 are approximately horizontal, the small opening diameters of the first and second air guide holes minimize the impact on airflow direction as it passes through the guide channel 3, the first air guide plate 1, and the second air guide plate 2.

[0060] In some embodiments, such as Figure 5 and Figure 6As shown, along the second direction, the width of the first air guide 11 is the same as the width of the second air guide plate 2; or, along the second direction, the width of the first air guide 11 is greater than the width of the second air guide plate 2.

[0061] When the first air guide plate 1 and the second air guide plate 2 are arranged opposite each other in a direction perpendicular to the first direction and the second direction, the multiple first air guide holes and the multiple second air guide holes are arranged opposite each other or staggered.

[0062] In some embodiments, as shown in the figure, the first air guide plate 1 includes a first air guide portion 11 and two first connecting portions 12. The two first connecting portions 12 are connected to both ends of the first air guide portion 11 along a first direction. The two first connecting portions 12 are rotatably connected to the main body 4 of the air conditioner. The first air guide portion 11 is provided with a plurality of sliding grooves at intervals along the first direction. The sliding grooves extend along a second direction, which is perpendicular to the first direction. The second air guide plate 2 includes a plurality of second sliding portions and a second air guide portion. The plurality of second sliding portions are connected to the side of the second air guide portion facing the first air guide portion 11. The plurality of second sliding portions correspond one-to-one with the plurality of sliding grooves.

[0063] It should be noted that the first air guide plate 1, the second air guide part and the multiple second sliding parts surround to form multiple flow guide channels 31, the multiple flow guide channels 31 are arranged along the first direction, and the multiple flow guide channels 31 extend along the second direction.

[0064] It is understandable that by setting multiple second sliding parts on the side of the second air guide facing the first air guide 11, not only can the second air guide be slidably connected, but the guide channel 3 formed by the second air guide and the first air guide 11 can also be divided into multiple guide channels 31, thereby further improving the airflow rate and achieving the lifting and guiding effect on the upper and lower airflows.

[0065] For example, the cross-sectional shape of the chute can be rectangular, inverted T-shaped, etc., preferably inverted T-shaped, and the cross-sectional shape of the second sliding part is set accordingly to restrict the second sliding part from leaving the chute in the direction away from the first air guide 11.

[0066] In some embodiments, the air guide structure further includes a driver disposed on the first air guide plate 1, the driver being used to drive the second air guide plate 2 to slide.

[0067] It should be noted that the actuator refers to a structure capable of driving the second air guide plate 2 to slide. The actuator may include a motor and a lead screw assembly. The nut of the lead screw assembly is fixedly connected to the second air guide plate 2, and the lead screw of the lead screw assembly is connected to the motor shaft of the motor through a coupling to realize the driving of the second air guide plate 2. The actuator may also be implemented using other publicly available driving methods.

[0068] It is understandable that the sliding and positioning of the second air guide plate 2 is controlled by starting and stopping the driver. When the first air guide plate 1 and the second air guide plate 2 are tilted, the driver is used to prevent the second air guide plate 2 from sliding unnecessarily and to control the extension length of the second air guide plate 2 relative to the first air guide plate 1.

[0069] In some embodiments, such as Figure 6 and Figure 7 As shown, at least a portion of the guide channel 3 gradually decreases in size along the air outlet direction of the guide channel 3.

[0070] It should be noted that "at least a portion of the guide channel 3 gradually decreases in size" means that at least a portion of the guide channel 3 away from the air conditioning unit body 4 gradually decreases in size. This means that along the direction of the guide channel 3 towards the air conditioning unit body 4, the cross-sectional area of ​​at least a portion of the guide channel 3 can remain constant. This ensures not only sufficient air intake for the guide channel 3 but also that the outflow velocity of the guide channel 3 is greater than the inflow velocity. Furthermore, the gradual decrease in the size of the guide channel 3 avoids vibrations and associated noise caused by a sudden drop in flow area.

[0071] In some embodiments, such as Figure 7 As shown, the distance between at least a portion of the surface of the second air guide plate 2 facing the first air guide plate 1 and the first air guide plate 1 gradually decreases along the air outlet direction of the guide channel 3.

[0072] Understandably, the size of the flow channel 3 can be controlled simply by adjusting the distance between the surface of the second air guide plate 2 facing the first air guide plate 1 and the first air guide plate 1. The surface of the second air guide plate 2 facing away from the first air guide plate 1 can be set into an arc surface with different curvatures according to actual flow requirements.

[0073] For example, when the first air guide plate 1 includes a first air guide portion 11 and two first connecting portions 12, the two ends of the second air guide plate 2 are respectively slidably connected to the grooves of the first connecting portions 12 along the first direction. Then, the surface of the second air guide plate 2 located outside the groove and facing the first air guide portion 11 is set as an arc surface with different curvatures according to the actual drainage requirements.

[0074] Specifically, when the first air guide plate 1 and the second air guide plate 2 are in a nearly horizontal state, the second air guide plate 2 is located outside the slide groove and at least a portion away from the air conditioning unit body 4, and gradually tilts upward along the first direction. According to the wall attachment effect, the second air guide plate 2 guides the airflow upward.

[0075] This application also provides an air conditioner indoor unit, which includes the above-mentioned air guide structure and main body 4. The specific structure of the air guide structure is as described in the above embodiments. Since this air conditioner indoor unit 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.

[0076] In some embodiments, the main body 4 includes a housing and a connecting arm, one end of which is slidably connected to the housing, and the other end of which is rotatably connected to the first air guide plate 1; the indoor unit of the air conditioner also includes a rotation drive and a sliding drive, the rotation drive is disposed on the connecting arm and is used to drive the first air guide plate 1 to rotate, and the sliding drive is disposed on the housing and is used to drive the connecting arm to be housed in the housing or to extend out of the housing.

[0077] It should be noted that the rotary drive component refers to a structure capable of driving the first air guide plate 1 to rotate. The sliding drive component refers to a structure capable of driving the connecting arm to slide. For example, the rotary drive component includes a rotary motor and a crank mechanism. The crank mechanism includes a crank and a connecting rod. The two ends of the crank are respectively connected to the motor shaft of the rotary motor and one end of the connecting rod. The other end of the connecting rod is connected to the air guide plate. The rotary motor drives the crank to perform circular motion. Due to the eccentric structure of the crank, when the crank rotates, it will drive the air guide plate to reciprocate around its fixed axis through the connecting rod, thus realizing the rotation of the air guide plate. The sliding drive component includes a sliding motor, a gear, and a rack. The rack is fixedly connected to the connecting arm, and the gear is fixedly connected to the motor shaft of the sliding motor. The gear meshes with the rack. The sliding motor drives the gear to rotate, thereby driving the rack and the connecting arm to slide. When the connecting arm is arc-shaped, the rack can have the same shape.

[0078] In the above embodiments, the descriptions of each embodiment have different focuses. Parts not described in detail in a particular embodiment can be referred to in the relevant descriptions of other embodiments. In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more features.
