Description

Technical Field

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

[0002] Existing air conditioners face difficulties in delivering cool air to the far reaches of a room during cooling operation due to the high density and sinking nature of cold air. Limited by the initial momentum of the airflow and its velocity decay after leaving the outlet, the airflow often fails to maintain horizontal kinetic energy and tends to sink rapidly near the outlet. This not only results in slow cooling and uneven temperature distribution at the far ends of the room, but also causes the sinking cold air to blow directly onto people below, causing discomfort and potential health hazards. Conversely, during heating operation, hot air, with its low density, rises easily. Limited by the downward penetrating power of the air jet, even when directed downwards, hot air often rises rapidly before reaching the ground or areas where people are active, accumulating at the top of the room. This leads to a large vertical temperature difference within the room, creating a "hot head, cold feet" phenomenon, reducing user comfort and wasting energy due to inefficient heat utilization. Therefore, there is an urgent need for an air guiding structure to solve the above-mentioned technical problems. Utility Model Content

[0003] The main purpose of this utility model is to provide an air guiding structure and its air conditioner to solve the above-mentioned technical problems.

[0004] In a first aspect, the present invention provides an air guiding structure, including a first air guiding plate and a first driving component. The first air guiding plate is configured to be rotatably disposed at the air outlet of the indoor unit of an air conditioner. The first driving component is connected to the first air guiding plate and is used to drive the first air guiding plate to rotate in order to adjust the air outlet angle. A second air guide plate is movably connected to the first air guide plate. The second air guide plate is driven by a second drive assembly. The second drive assembly is configured to drive the air guide path of the second air guide plate relative to the first air guide plate to switch between an extended state and a retracted state. In the extended state, the second air guide plate and the first air guide plate together form a continuous extended air duct.

[0005] The first air guide plate has a first side and a second side that are disposed opposite to each other along the width direction; the first side and the second side are connected to form a receiving cavity on the air guiding surface of the first air guide plate; the second air guide plate is slidably disposed in the receiving cavity.

[0006] The first air guide plate is provided with a first guide structure, and the second air guide plate is provided with a second guide structure; the first guide structure and the second guide structure cooperate to guide the second air guide plate to switch between the extended state and the retracted state in the receiving cavity according to the air guiding path.

[0007] The first air guide plate has guide grooves on its opposite inner sidewalls that communicate with the receiving cavity. The opposite ends of the guide grooves extend to the first sidewall and the second sidewall to form the first guide structure. The opposite ends of the second air guide plate extend into the corresponding guide grooves to form the second guide structure.

[0008] Both the first air guide plate and the second air guide plate are arc-shaped plates, and both the receiving cavity and the guide groove include arc-shaped guide sections, so that the second air guide plate can slide along the arc-shaped guide sections under the drive of the second driving component.

[0009] The first drive assembly includes a first drive motor and a transmission shaft, wherein the transmission shaft is connected to the output shaft of the first drive motor and the first air guide plate, respectively.

[0010] The second drive assembly is respectively provided between the two ends of the first air guide plate that are arranged opposite each other in the length direction and the corresponding ends of the second air guide plate.

[0011] The second drive assembly includes a second drive motor, a gear, and a rack; the second drive motor is disposed on the first air guide plate, the gear is connected to the output shaft of the second drive motor, and the rack is disposed on the second air guide plate and meshes with the gear.

[0012] The first air guide plate and / or the second air guide plate are provided with a turbulence guiding structure, which includes a plurality of protruding guide vanes.

[0013] Secondly, this utility model also provides an air conditioner, including an indoor unit, wherein the air outlet of the indoor unit is provided with an air guiding structure as described in the first aspect, and a drive rod assembly is provided between the air outlet and the first air guiding plate of the air guiding structure.

[0014] The beneficial technical effects of this utility model are as follows: This utility model sets a rotatable first air guide plate at the air outlet of the indoor unit of the air conditioner, and movably connects a second air guide plate driven by a second drive assembly to the first air guide plate. This allows the second air guide plate to switch between an extended state and a retracted state. When extended, it forms a continuous extended air duct together with the first air guide plate. Based on the adjustment of the air outlet angle of the first air guide plate by the first drive assembly, the length of the controlled air duct outside the air outlet is further extended, ensuring that the airflow is always constrained along a predetermined direction over a longer distance. This reduces the problems of immediate diffusion and rapid momentum decay after leaving the outlet, effectively increasing the effective distance of the air jet and improving the phenomenon of slow cooling or heating and uneven temperature distribution at the far end of the room. During cooling operation, the first air guide plate can be adjusted to a horizontal or... The first air guide plate extends upwards, driving the second air guide plate to extend further upwards, creating an upward or distal air duct. This allows cool air to be delivered to the upper, distal part of the room before slowly descending, reducing the discomfort of cold air rapidly descending near the air outlet and "direct cold air blowing" on the body. During heating operation, the first air guide plate can be adjusted downwards and extended in conjunction with the second air guide plate to form an extended air duct pointing towards the ground. This guides hot air directly to the ground area where people are active before it rises and diffuses, alleviating the "hot head, cold feet" situation and the accumulation of heat at the top, improving heat utilization efficiency and user comfort. At the same time, by switching between the extended and retracted states of the second air guide plate, the air duct can be converted between two lengths, allowing for the selection of long-distance centralized air supply or short-distance diffused air supply according to room size and operating conditions, making the air guiding method more flexible and diverse.

[0022] Please also refer to Figures 1-10 This utility model provides an air guiding structure, mainly applied to an indoor air conditioning unit 1, designed to improve air delivery through a variable structural form. The air guiding structure includes a first air guide plate 2 and a first driving assembly. The first air guide plate 2 is rotatably disposed at the air outlet 11 of the indoor air conditioning unit 1. The first driving assembly is connected to the first air guide plate 2 and drives the first air guide plate 2 to rotate to adjust the air outlet angle. A second air guide plate 4 is movably connected to the first air guide plate 2. The second air guide plate 4 is drively connected to the second driving assembly, which is configured to drive the air guiding path of the second air guide plate 4 relative to the first air guide plate 2 to switch between an extended state and a retracted state. In the extended state, the second air guide plate 4 and the first air guide plate 2 together form a continuous extended air duct.

[0023] In this embodiment, the air guiding structure includes a first air guiding plate 2, a first driving component, a second air guiding plate 4, and a second driving component.

[0024] The first air guide plate 2 is generally a strip-shaped plate, with its length direction basically consistent with the length direction of the air outlet 11, so that it can cover the entire area of ​​the air outlet 11 when rotating. The two ends of the first air guide plate 2 are rotatably connected to the indoor unit housing through pivot connectors, allowing the first air guide plate 2 to swing relative to the air outlet 11 about a rotation axis that extends approximately along its length direction. Through this swinging, the guiding surface of the first air guide plate 2 can be continuously adjusted within a predetermined range to change the overall jet direction of the airflow, such as achieving upward airflow, horizontal airflow, or downward airflow.

[0025] The first drive assembly is connected to the first air guide plate 2 via a transmission mechanism and is used to drive the first air guide plate 2 to rotate in order to adjust the air outlet angle. The first drive assembly can be in the form of a motor and a transmission mechanism, or it can be a conventional structure such as an electric push rod, a stepper motor and a crank-connecting rod mechanism. In this embodiment, after receiving a control signal, the first drive assembly outputs a driving torque or thrust, which drives the first air guide plate 2 to swing around its rotation axis through the transmission component fixed to the first air guide plate 2, thereby realizing the adjustment of the air outlet angle.

[0026] A second air guide plate 4 is movably connected to the first air guide plate 2. The second air guide plate 4 is also a strip-shaped plate, its width matching the width of the first air guide plate 2, and its length direction being substantially parallel to the length direction of the first air guide plate 2. The second air guide plate 4 is movably mounted on the first air guide plate 2, allowing it to move relative to the first air guide plate 2 along a pre-defined airflow path. The overall direction of the airflow path is substantially consistent with the airflow direction of the first air guide plate 2, ensuring a smooth transition between the airflow surface of the second air guide plate 4 and the airflow surface of the first air guide plate 2 at different positions. Figure 1 and Figure 3 As shown, the second air guide plate 4 is located on the upper surface of the first air guide plate 2. When the second air guide plate 4 is not in the extended state, it serves as the main air guiding component.

[0027] The second drive assembly is located on or near the first air guide plate 2 and is drively connected to the second air guide plate 4. Under the action of a control signal, the second drive assembly drives the second air guide plate 4 to move along the aforementioned air guide path, thereby switching the second air guide plate 4 between an extended state and a retracted state. Specifically: In the retracted state, the second air guide plate 4 and the first air guide plate 2 basically overlap. At this time, most or all of the air guiding surface of the second air guide plate 4 is located within the outline of the first air guide plate 2. The air guiding structure formed by the first air guide plate 2 and the second air guide plate 4 is relatively narrow, which is suitable for short-distance air supply or operating conditions that require more diffused airflow. In the extended state, the second drive assembly drives the second air guide plate 4 to move from the side near the air outlet 11 to the direction away from the air outlet 11, so that at least a portion of the air guide surface of the second air guide plate 4 is located outside the first air guide plate 2, thereby spatially extending the air duct extending outward from the air outlet 11 along the airflow direction. At this time, the air guide surfaces of the second air guide plate 4 and the first air guide plate 2 are continuously connected in position without obvious interruption, and the two together define a continuous extended air duct outside the air outlet 11.

[0028] When the indoor unit 1 of the air conditioner is working, the fan blows air out from the air outlet 11. The airflow is first guided along the guide surface of the first air guide plate 2, then enters the extension formed by the second air guide plate 4, and finally exits from the side of the second air guide plate 4 away from the air outlet 11. By adjusting the extension or retraction of the second air guide plate 4 by the second drive assembly, the effective length of the continuous air duct can be changed: when it is necessary to send airflow to a farther area of ​​the room, the second air guide plate 4 is driven to the extended state, thereby forming a longer extended air duct, so that the airflow is always constrained before leaving the air guide plate, forming a concentrated jet with a slower velocity decay, and realizing long-distance air delivery; when only local air delivery is needed, the second air guide plate 4 can be driven to the retracted state, shortening the air duct length and allowing the airflow to disperse earlier.

[0029] Furthermore, by adjusting the rotation position of the first air guide plate 2 through the first drive component, the overall direction of the continuously extending air duct can be changed under different operating conditions. For example, in cooling mode, the first air guide plate 2 can be adjusted to tilt upwards and the second air guide plate 4 can be extended appropriately, so that the cold air is sent to the far end of the room along the upward-tilted extended air duct and then slowly sinks under the action of gravity; in heating mode, the first air guide plate 2 can be adjusted to tilt downwards or forwards and downwards, and in conjunction with the extension of the second air guide plate 4, the hot air is sent to the human activity area along the extended air duct pointing to the ground, thereby improving the room temperature distribution and human comfort.

[0030] In this embodiment, the specific structure and control method of the first driving component and the second driving component can be modified in various ways according to actual needs, as long as the following can be achieved: the first air guide plate 2 is rotatably installed relative to the air outlet 11 and rotates to adjust the air outlet angle under the action of the first driving component; the second air guide plate 4 switches between an extended state and a retracted state relative to the first air guide plate 2 on the air guide path under the drive of the second driving component, and forms a continuous extended air duct together with the first air guide plate 2 in the extended state.

[0031] In one embodiment, the first air guide plate 2 has a first side surface 21 and a second side surface 22 disposed opposite to each other along the width direction; the first side surface 21 and the second side surface 22 are connected to form a receiving cavity 25 on the air guiding surface of the first air guide plate 2; the second air guide plate 4 is slidably disposed in the receiving cavity 25.

[0032] In this embodiment, as Figure 3 As shown, the first air guide plate 2 has a first side surface 21 and a second side surface 22 arranged along its width direction, and the first side surface 21 and the second side surface 22 form the edge boundary of the first air guide plate 2. The surface of the first air guide plate 2 facing the airflow is the air guiding surface, which faces the indoor space and is used to contact the airflow and guide the airflow.

[0033] A receiving cavity 25 extending along the length of the first air guide plate 2 is formed on the air guide surface of the first air guide plate 2. This receiving cavity 25 can be integrally formed during injection molding or post-processed and recessed into the air guide surface of the first air guide plate 2. The opening of the receiving cavity 25 is connected to the air guide surface, and its two sides are respectively connected to the first side surface 21 and the second side surface 22, so that the receiving cavity 25 penetrates through the first side surface 21 and the second side surface 22 in the width direction of the first air guide plate 2. The receiving cavity 25 can be considered as an open channel structure opened on the air guide surface of the first air guide plate 2, and this channel structure has three openings. Taking a horizontal setting of the first air guide plate 2 as an example, the top surface of this channel structure is one opening, the left side is the second opening, and the right side is the third opening.

[0034] The cavity depth of the receiving cavity 25 extends along the thickness direction of the first air guide plate 2, and its cross-sectional shape is set according to the cross-sectional shape of the second air guide plate 4, so that the second air guide plate 4 can slide within the receiving cavity 25.

[0035] The thickness of the second air guide plate 4 is less than that of the first air guide plate 2, allowing the second air guide plate 4 to be completely contained within the receiving cavity 25. The surface of the second air guide plate 4 furthest from the first air guide plate 2 serves as its air guiding surface, and structurally it is spaced apart from the air guiding surface of the first air guide plate 2. When the second air guide plate 4 is fully retracted into the receiving cavity 25, the air guiding surface of the second air guide plate 4 is parallel to the air guiding surface of the first air guide plate 2.

[0036] The second air guide plate 4 is slidably disposed in the receiving cavity 25, and forms a sliding fit relationship with the side wall and bottom surface of the receiving cavity 25.

[0037] like Figure 7 As shown, when the second air guide plate 4 is in the retracted state, it is almost entirely located inside the receiving cavity 25. At this time, the air guiding structure extending from the air outlet 11 to the indoor space is mainly formed by the second air guide plate 4. The overall air duct length is relatively short, suitable for short-distance air delivery or maintaining a large air delivery diffusion angle. When it is necessary to increase the air delivery distance or change the airflow shape, the second drive assembly drives the second air guide plate 4 to slide along the receiving cavity 25, causing a portion of the second air guide plate 4 to extend outward from the opening of the receiving cavity 25 away from the air outlet 11, forming an extension section outside the air guide surface of the first air guide plate 2. The air guide surface of the second air guide plate 4 is spatially continuous with the air guide surface of the first air guide plate 2, thereby forming a continuous extended air duct outside the air outlet 11, achieving further constraint and guidance of the airflow.

[0038] Through the above structural design, the receiving cavity 25 formed by the first air guide plate 2 limits and guides the movement of the second air guide plate 4, ensuring that the second air guide plate 4 slides smoothly along the predetermined air guiding path during its extension and retraction. The overall air guiding structure can construct continuous air ducts of different lengths and directions under different working conditions by adjusting the swing angle of the first air guide plate 2 and the extension and retraction position of the second air guide plate 4 in the receiving cavity 25, thereby meeting the needs of long-distance air delivery and comfortable air delivery.

[0039] In one embodiment, the extended state includes a first extended state and a second extended state; in the first extended state, the second air guide plate 4 extends from the first side 21, and the second air guide plate 4 cooperates with the first air guide plate 2 to guide airflow in a first direction; in the second extended state, the second air guide plate 4 extends from the second side 22, and the second air guide plate 4 cooperates with the first air guide plate 2 to guide airflow in a second direction.

[0040] In this embodiment, the two sides of the first air guide plate 2 that are arranged opposite each other along the width direction (i.e., the airflow direction) are defined as the first side 21 and the second side 22, respectively. The receiving cavity 25 is connected through the first side 21 and the second side 22, so that the second air guide plate 4 can selectively extend from one of them.

[0041] The first air guide plate 2 is configured to be rotatably mounted, and its rotation state corresponds to the extension state of the second air guide plate 4. The extension state includes a first extension state and a second extension state. First extended state (corresponding to cooling mode): In this state, the first drive assembly drives the first air guide plate 2 to rotate to a first preset angle (e.g., horizontal or slightly upward). At this time, the first side 21 of the first air guide plate 2 faces outward away from the air outlet 11 (i.e., towards the indoor space). Simultaneously, the second drive assembly drives the second air guide plate 4 to slide towards the first side 21 within the receiving cavity 25 until it extends a predetermined distance from the first side 21. At this time, the extended second air guide plate 4 and the first air guide plate 2 work together to form an outwardly extending air duct to guide airflow along a first direction (e.g., diagonally upward). This first direction facilitates the long-distance delivery of cold air to the upper area of ​​the room, utilizing the principle of cold air sinking to achieve "shower-like" cooling and avoiding direct cold air blowing on the human body.

[0042] Second extended state (corresponding to heating mode): In this state, the first drive assembly drives the first air guide plate 2 to rotate to a second preset angle (e.g., diagonally downward). Based on the rotation characteristics of the first air guide plate 2, the first side 21 rotates to a position close to the inner side of the air outlet 11 (i.e., as the inner side), while the opposite second side 22 faces downward. Simultaneously, the second drive assembly drives the second air guide plate 4 to slide within the receiving cavity 25 towards the second side 22 until it extends out from the second side 22. At this time, the extended second air guide plate 4 cooperates with the first air guide plate 2 to form a downward-extending air duct, guiding airflow along a second direction (e.g., downward). This second direction facilitates the direct delivery of hot air to the ground area, utilizing the principle of hot air rising to achieve "carpet-like" heating, solving the problem of cold feet caused by hot air rising.

[0043] With the above settings, the air guiding structure of this embodiment not only changes the basic air direction by rotating the first air guide plate 2, but also uses the extension of the second air guide plate 4 from different sides to dynamically construct the extended air duct that is most suitable for the physical characteristics of the mode in different modes, thereby improving the comfort of the air conditioner.

[0044] In one embodiment, the first air guide plate 2 is provided with a first guide structure, and the second air guide plate 4 is provided with a second guide structure; the first guide structure cooperates with the second guide structure to guide the second air guide plate 4 to switch between the extended state and the retracted state in the receiving cavity 25 according to the air guiding path.

[0045] In this embodiment, to ensure the controllable movement of the second air guide plate 4 within the receiving cavity 25, a first guide structure is provided on the first air guide plate 2, and a second guide structure is provided on the second air guide plate 4. The first guide structure and the second guide structure are shaped to match and cooperate with each other, jointly defining the movement path of the second air guide plate 4.

[0046] Specifically, the first guide structure is disposed inside or at the edge of the receiving cavity 25. In an optional embodiment, the first guide structure may be a guide protrusion 711, a guide rib, or a guide groove 26 extending along the airflow direction of the first air guide plate 2. Correspondingly, the second guide structure is disposed on the surface or edge of the second air guide plate 4, and may be a groove 721 that mates with the aforementioned guide protrusion 711, or a slider or flange that mates with the aforementioned guide groove 26.

[0047] Through the cooperation of the first guide structure and the second guide structure (e.g., the engagement of the groove 721 and the guide protrusion 711), the second air guide plate 4 is restricted to moving only along the air guide path set by the first air guide plate 2 (i.e., the extension direction of the receiving cavity 25), thus limiting its displacement and rotation perpendicular to the sliding direction. This cooperation not only supports the second air guide plate 4 and prevents it from falling out of the receiving cavity 25, but more importantly, it guides the second air guide plate 4 to smoothly switch between the extended state and the retracted state within the receiving cavity 25 according to the air guide path.

[0048] When the second drive component applies a driving force, the second air guide plate 4, relying on the sliding of the second guide structure on the first guide structure, can smoothly extend or retract from the receiving cavity 25, thereby changing the overall length of the air guide structure and realizing the dynamic expansion of the air duct. This guiding and coordinating structure ensures that even when the air velocity at the air conditioning outlet 11 is high and the airflow impact force is strong, the extended second air guide plate 4 can still remain stable and will not vibrate or generate noise.

[0049] In one embodiment, the opposite inner walls of the first air guide plate are respectively provided with guide grooves 26 communicating with the receiving cavity 25, and the opposite ends of the guide grooves 26 extend to the first side 21 and the second side 22 respectively to form the first guide structure; the opposite ends of the second air guide plate extend into the corresponding guide grooves 26 to form the second guide structure.

[0050] In this embodiment, the first air guide plate 2 has two opposing inner sidewalls, each with a guide groove 26. The guide groove 26 extends along the air guiding direction (i.e., the width direction) of the first air guide plate 2 and communicates with the internal space of the receiving cavity 25, forming a continuous guide path. The opposite ends of the guide groove 26 extend to the first side surface 21 and the second side surface 22, respectively, thus allowing the guide groove 26 to penetrate the entire width of the first air guide plate 2, forming the first guide structure. This allows the second air guide plate 4 to slide out or retract along the guide groove 26 from either side (first side surface 21 or second side surface 22).

[0051] The two opposite ends (i.e., the two ends along its length) of the second air guide plate 4 extend into the corresponding guide grooves 26. Specifically, the two ends of the second air guide plate 4 may form protruding structures or slider-like extensions 42, which are embedded in the guide grooves 26 to form the second guide structure. Through this embedded fit, the movement of the second air guide plate 4 within the receiving cavity 25 is restricted by the guide grooves 26, allowing it to slide along the path of the guide grooves 26 and preventing it from deflecting in the vertical direction.

[0052] In actual operation, when the second drive assembly drives the second air guide plate 4, both ends of the second air guide plate 4 slide within the guide groove 26, achieving smooth reciprocating motion. For example, in the extended state, the second air guide plate 4 can extend from the first side 21 or the second side 22, and the guide groove 26 ensures that its extension trajectory remains connected with the air guiding surface of the first air guide plate 2; in the retracted state, the second air guide plate 4 is completely retracted into the receiving cavity 25. This structure not only enhances the motion stability of the second air guide plate 4, but also facilitates rapid switching between different modes (such as the first extended state or the second extended state), ensuring that the overall air guiding structure forms a continuous extended air duct.

[0053] In one embodiment, both the first air guide plate 2 and the second air guide plate 4 are arc-shaped plates, and both the receiving cavity 25 and the guide groove 26 include arc-shaped guide sections, so that the second air guide plate 4 can slide along the arc-shaped guide sections under the drive of the second driving component.

[0054] In this embodiment, the first air guide plate 2 has an overall arc-shaped plate structure, and its air guiding surface forms a continuous arc-shaped surface along the width direction (i.e., the airflow direction). The curvature of this arc-shaped surface can be designed according to the shape of the air conditioning outlet 11 and the air supply requirements, for example, it can be a circular arc or an elliptical arc, so that the airflow can flow smoothly and reduce resistance when passing through. Correspondingly, the second air guide plate 4 also has an arc-shaped plate structure, and its curvature matches the arc-shaped surface of the first air guide plate 2, so that it can closely fit the air guiding surface of the first air guide plate 2 when sliding.

[0055] In this arc-shaped design, the receiving cavity 25 as a whole includes an arc-shaped guide section, which extends along the arc-shaped contour of the first air guide plate 2 to form a curved cavity path. Specifically, the inner wall of the receiving cavity 25 (including the part connected to the first side 21 and the second side 22) is arc-shaped and extends in an arc-shaped direction.

[0056] Similarly, the guide groove 26 also includes an arc-shaped guide section. This arc-shaped guide section forms a continuous arc-shaped inner wall along the length of the guide groove 26, extending to the first side surface 21 and the second side surface 22 at opposite ends. The arc-shaped design of the guide groove 26 ensures that its path is consistent with the arc-shaped guide section of the receiving cavity 25, thus ensuring that the sliding trajectory of the second air guide plate 4 is an arc-shaped movement.

[0057] With the above configuration, the second air guide plate 4 can slide within the receiving cavity 25 along the arc-shaped guide section under the drive of the second drive assembly. The specific working process is as follows: In the retracted state, the second air guide plate 4 is completely contained within the arc-shaped cavity of the receiving cavity 25; in the extended state, the arc-shaped structure of the second air guide plate 4 gradually extends along the arc-shaped guide section, its movement trajectory being arc-shaped, thus causing the extended portion to naturally deflect relative to the first air guide plate 2. For example, in heating mode, when the first air guide plate 2 rotates to a downward position, the second air guide plate 4 extends along the arc-shaped guide section, and its end gradually deflects downward relative to the end of the first air guide plate 2, forming an extended air duct pointing towards the ground, which is beneficial for delivering hot air close to the ground.

[0058] The design of this curved plate and curved guide section ensures that the overall air guiding structure can dynamically adjust the duct shape according to the buoyancy or gravity characteristics of the airflow (such as hot air rising or cold air sinking), thereby improving air delivery efficiency and comfort.

[0059] In one embodiment, the first drive assembly includes a first drive motor 61 and a drive shaft, the drive shaft being connected to the output shaft of the first drive motor 61 and the first air guide plate 2, respectively.

[0060] In this embodiment, the first driving component provides rotational power to the first air guide plate 2 to change its angle at the air outlet 11. The first driving component mainly includes a first drive motor 61 and a transmission shaft, such as... Figure 3 As shown, the drive shaft is not shown separately inside the first drive motor 61. The output shaft of the first drive motor 61 can be directly fixedly connected to one end of the drive shaft, or connected to the drive shaft through a reduction mechanism to provide greater torque. The other end of the drive shaft extends to the end of the first air guide plate 2 and forms a rigid connection with the first air guide plate 2, enabling both to rotate synchronously. In some embodiments, the drive shaft can be integrally formed with the first air guide plate 2, or fastened by means of insertion, screw fixing, etc.

[0061] During operation, when the control unit (not shown in the attached diagram) issues a command, the first drive motor 61 starts and drives its output shaft to rotate. The transmission shaft rotates accordingly, thereby causing the first air guide plate 2 connected to the transmission shaft to rotate around the axis of the transmission shaft. By controlling the rotation direction and angle of the first drive motor 61, the tilt angle of the first air guide plate 2 (such as upward, downward, or horizontal) can be adjusted, thereby changing the basic airflow direction of the air outlet 11. For example, in cooling mode, the first drive motor 61 drives the first air guide plate 2 to rotate upward to a horizontal or slightly upward position; in heating mode, it drives the first air guide plate 2 to rotate downward to a vertical or tilted downward position.

[0062] The first drive component has a simple structure and direct transmission, which can provide stable and reliable rotational power for the first air guide plate 2, ensuring that the air guide plate can respond quickly and accurately reach the preset angle under different operating modes, thereby realizing air guidance control.

[0063] In one embodiment, the second driving component is respectively disposed between the two ends of the first air guide plate 2 that are disposed opposite to each other in the length direction and the ends corresponding to the second air guide plate 4.

[0064] In this embodiment, the first air guide plate 2 has two ends arranged opposite each other along its length. The second air guide plate 4, as a component nested within the first air guide plate 2, also has corresponding ends at corresponding positions. To ensure force balance and smooth movement of the second air guide plate 4 during extension and retraction, the second drive assembly is respectively disposed between the two ends of the first air guide plate 2 and the corresponding ends of the second air guide plate 4.

[0065] Specifically, a second drive assembly can be installed at both the left and right ends of the first air guide plate 2, with the left and right sides facing the indoor unit 1 of the air conditioner as the reference. These two sets of drive assemblies cooperate to drive the second air guide plate 4 to move relative to the first air guide plate 2. This dual-sided drive layout allows the driving force to be evenly applied to both ends of the second air guide plate 4, effectively avoiding problems such as jamming, deflection, or poor movement caused by unilateral force.

[0066] In one embodiment, the second drive assembly includes a second drive motor 5, a gear 511, and a rack 41; the second drive motor 5 is disposed on the first air guide plate 2, the gear 511 is connected to the output shaft of the second drive motor 5, and the rack 41 is disposed on the second air guide plate 4 and meshes with the gear 511.

[0067] In this embodiment, the second drive component adopts a gear 511 and rack 41 transmission mechanism, which mainly includes a second drive motor 5, a gear 511 and a rack 41.

[0068] The second drive motor 5 is fixedly mounted on the first air guide plate 2. The gear 511 is connected to the output shaft of the second drive motor 5 and serves as the drive wheel.

[0069] The rack 41 is disposed on the second air guide plate 4 and extends along the sliding direction of the second air guide plate 4. The rack 41 can be directly integrally formed on the second air guide plate 4, or it can be fixedly installed on the second air guide plate 4 as an independent component. The rack 41 meshes with the gear 511 to form a transmission pair.

[0070] The working principle is as follows: When the control unit issues a command, the second drive motor 5 starts to rotate, driving the gear 511 on its output shaft to rotate. Since the gear 511 meshes with the rack 41, the rotational motion of the gear 511 is converted into the movement of the rack 41 along an arc, thereby driving the second air guide plate 4, which is fixed with the rack 41, to move along the guide path of the first air guide plate 2. By controlling the forward or reverse rotation of the second drive motor 5, the second air guide plate 4 can be driven to switch between the extended and retracted states. This gear 511 and rack 41 transmission method has a compact structure, high transmission efficiency, and precise control, making it very suitable for the extension and retraction drive of air guide plates.

[0071] In one embodiment, a turbulence guiding structure is provided on the air guiding surface of the first air guide plate 2 and / or the second air guide plate 4, the turbulence guiding structure including a plurality of protruding guide vanes 81.

[0072] In this embodiment, as Figure 1 and Figure 5 As shown, the turbulence guiding structure is mainly distributed on the air guide surface of the second air guide plate 4. The turbulence guiding structure includes multiple protruding guide vanes 81. These guide vanes 81 can be tiny protrusions. For example, the guide vanes 81 can be designed as fine ribs arranged along the airflow direction, or as micro-wing-shaped protrusions distributed in an array.

[0073] When high-speed airflow passes over a smooth surface, boundary layer separation is easily generated, leading to unstable vortices, increased wind noise, and reduced wind power. However, by setting multiple raised guide vanes 81 on the guide surface, small disturbances can be artificially introduced into the boundary layer, transforming the laminar boundary layer into a turbulent one. The turbulent boundary layer has higher energy and adheres better to the guide vane surface, thus delaying airflow separation and reducing the generation of large-scale vortices. This not only reduces the noise (wind noise) of airflow passing through the guide structure but also allows the airflow to flow more smoothly and steadily along the direction of the guide structure, improving the delivery distance and comfort.

[0074] like Figure 11As shown, corresponding to the above-mentioned air guiding structure, this utility model embodiment also provides an air conditioner, which includes an indoor unit 1. The air outlet 11 of the indoor unit 1 is provided with the air guiding structure described in the aforementioned embodiment, and a drive rod assembly 3 is provided between the air outlet 11 and the first air guiding plate 2 of the air guiding structure.

[0075] In this embodiment, the air conditioner includes an indoor unit 1. An air outlet 11 is provided at the lower part of the casing of the indoor unit 1 for delivering regulated airflow to the indoor environment. An air guide structure 12, as described in the previous embodiment, is provided at the air outlet 11. The air guide structure 12 includes a rotatable first air guide plate 2 and a second air guide plate 4 that can extend and retract from the first air guide plate 2, thereby achieving dynamic expansion and directional adjustment of the air duct through their cooperation.

[0076] To coordinate with the overall movement of the air guiding structure, a drive rod assembly 3 is provided between the air outlet 11 and the first air guide plate 2 of the air guiding structure. The drive rod assembly 3 is the mechanism that realizes the overall displacement of the first air guide plate 2.

[0077] Specifically, refer to Figure 1 One end of the drive rod assembly 3 is connected to the internal structure of the indoor unit 1 of the air conditioner (e.g., the inner wall of the air outlet 11), and the other end is connected to the first air guide plate 2. The drive rod assembly 3 can be an electric push rod, a telescopic linkage mechanism, or a crank-slider mechanism, or other devices capable of producing linear or arc displacement.

[0078] The main function of the drive rod assembly 3 is to drive the first air guide plate 2 to move between the "retracted position" and the "working position": Retraction position: When the air conditioner is in the off state, the drive rod assembly 3 moves (e.g., retracts) to pull the first air guide plate 2 back towards the inside of the air outlet 11 until the first air guide plate 2 (and the second air guide plate 4 housed inside it) is in close contact with or covers the air outlet 11.

[0079] Operating position: When the air conditioner is turned on, the drive rod assembly 3 actuates (e.g., extends), pushing the first air guide plate 2 outward a certain distance from the air outlet 11. This pushing action allows the first air guide plate 2 to break free from the obstruction of the housing, providing the necessary spatial freedom for its subsequent rotation (driven by the first drive assembly). Through the cooperation of the drive rod assembly 3 and the aforementioned air guide structure, the air conditioner of this embodiment can achieve comfortable air delivery over long distances without direct airflow.

[0080] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
