Description

Technical Field

[0001] This invention relates to the field of air supply equipment technology, and in particular to an air duct structure, air duct components, cabinet air conditioner, and air outlet control method for cabinet air conditioner. Background Technology

[0002] In existing technologies, air outlets typically incorporate sweeping or guiding mechanisms, using multiple small guide vanes to direct airflow in left-right directions. However, assembling multiple guide vanes is cumbersome and inefficient. In cooling or heating modes, the airflow follows the direction of the guide vanes, resulting in a unidirectional airflow that cannot diffuse simultaneously in all directions. Currently, in the air conditioning industry, downward-facing air outlets blow air forward, causing the airflow to quickly reach the ground, reducing the airflow distance, and also posing a risk of dust generation.

[0003] like Figure 1 As shown, in the existing technology, a large air guide plate is used instead of multiple small air guide plates to improve assembly and increase production efficiency. The driving method is direct motor drive, and the air guide plate rotates in a circular motion around the motor shaft. However, this driving method is not stable, and the air guide plate is prone to shaking when the air volume is large. Summary of the Invention

[0004] To overcome the problem of air guide vanes being prone to vibration when directly driven by a motor in related technologies, this invention proposes an air duct structure, an air duct assembly, a cabinet air conditioner, and an air outlet control method for the cabinet air conditioner. This involves setting a first and a second mutually perpendicular slide rail on a first air duct housing, and setting a first sliding member that slides with the first slide rail and a second sliding member that slides with the second slide rail on the air guide vane. When the first and second sliding members slide within their respective slide rails, they can cause the air guide vane to rotate, thereby achieving the air guiding effect. Simultaneously, the first and second slide rails can also limit the movement of the first and second sliding members, thus preventing vibration of the air guide vane during air guiding.

[0005] The first aspect of this invention provides an air duct structure, comprising:

[0006] The first air duct housing has an air inlet and an air outlet. The air duct wall of the first air duct housing is provided with a first slide and a second slide that are perpendicular to each other. The first slide extends from the side away from the air outlet to the side closer to the air outlet, and the second slide extends from the bottom side of the air outlet to the top side of the air outlet.

[0007] An air guide plate is located at the air outlet. The air guide plate includes a plate body for guiding airflow and a first sliding member and a second sliding member disposed on the plate body. The first sliding member is slidably embedded in a first slide rail, and the second sliding member is slidably embedded in a second slide rail. When one of the first sliding member and the second sliding member is driven to slide along its slide rail, the other can slide synchronously within its slide rail.

[0008] The plate is configured such that when the first slider slides along the first slide rail and the second slider slides along the second slide rail, the plate can be rotated by the first and second sliders, thereby changing the flow direction of the plate.

[0009] In the above technical solution, the first slide rail includes a first slide rail end A located close to the air outlet and a first slide rail end B located away from the air outlet in its extending direction.

[0010] The second slide rail includes, in its extending direction, a second slide rail end A near the bottom of the air outlet and a second slide rail end B near the top of the air outlet;

[0011] The projection of the first slide rail onto the second slide rail is located between end A of the second slide rail and end B of the second slide rail;

[0012] When one of the first and second sliding members is driven to move from end A to end B along its corresponding slide, the other can move synchronously from end A to end B within its corresponding slide. When one of the first and second sliding members is driven to move from end B to end A along its corresponding slide, the other can also move synchronously from end B to end A within its corresponding slide.

[0013] The plate has a closed position for closing the air outlet and a guide position for opening the air outlet. When the plate is in the closed position, the first sliding member is located at position A at the end of the first slide rail, and the second sliding member is located at position A at the end of the second slide rail.

[0014] When one of the first and second sliding members is driven to move along its corresponding slide from end A to end B, the air guide plate can be rotated to switch the plate from the closed position to the air guide position.

[0015] In the above technical solution, the second slide rail includes a second slide rail position C between the second slide rail end position A and the second slide rail end position B in its extension direction, and the second slide rail position C is at the same height as the first slide rail.

[0016] in

[0017] When the second sliding member is located between position A at the end of the second slide rail and position C at the second slide rail, a guide air duct is formed between the plate and the first air duct housing in a gradually narrowing form from the air inlet side to the air outlet side.

[0018] When the second sliding member is located between position B at the end of the second slide rail and position C of the second slide rail, a guide air duct with a gradually expanding shape from the air inlet side to the air outlet side is formed between the plate and the first air duct shell.

[0019] In the above technical solution, the first air duct shell includes air duct sidewalls arranged opposite to each other and air duct bottom wall, air duct top wall and air duct front wall between the two air duct sidewalls, and the air duct front wall forms an air outlet; the first slide and the second slide are each provided in two sets, wherein each air duct sidewall is provided with a set of first slide and second slide, and the first slides on the two air duct sidewalls are symmetrically arranged, and the second slides on the two air duct sidewalls are also symmetrically arranged;

[0020] The first and second slides on the sidewall of each air duct are set independently of each other, and the second slide is located between the first slide and the air outlet.

[0021] The plate body includes plate sidewalls arranged opposite each other, each plate sidewall corresponds to an air duct sidewall, and each plate sidewall is provided with a first sliding member and a second sliding member.

[0022] The first sliding member is embedded in the first slide rail, and the second sliding member is embedded in the second slide rail.

[0023] In the above technical solution, the bottom wall of the air duct includes an outer bottom wall and an inner bottom wall of the air duct. The inner bottom wall of the air duct is constructed as an upwardly extending inclined wall from the air inlet side to the air outlet side. The upward inclination angle α of the inner bottom wall of the air duct is between 3° and 10°.

[0024] When the second sliding member moves to position B at the end of the second slide, the plate is parallel to the bottom wall of the air duct.

[0025] In the above technical solution, the top wall of the air duct includes the outer top wall and the inner top wall of the air duct.

[0026] The maximum distance from the first slide to the top wall of the air duct is d1, and the maximum distance from the first slide to the bottom wall of the air duct is d2, where d1 < d2.

[0027] In the above technical solution, the air duct structure also includes:

[0028] The second air duct shell and the connecting air duct shell are in fluid communication with the first air duct shell through the connecting air duct shell. The interior of the second air duct shell is constructed to form a second air supply duct extending in a second direction. The interior of the first air duct shell is constructed to form a first air supply duct extending in a first direction. The second direction is different from the first direction.

[0029] The connecting air duct shell is provided with a flow guiding structure, which is used to guide the airflow flowing in the second direction in the second air duct shell to the first air duct shell in the first direction.

[0030] Preferably, the first air duct shell, the connecting air duct shell, and the second air duct shell are integrally formed.

[0031] A second aspect of the present invention provides an air duct assembly, including a drive mechanism and the air duct structure described above;

[0032] The drive mechanism is used to drive at least one of the first slider and the second slider to move within their respective tracks.

[0033] In the above technical solution, the driving mechanism includes:

[0034] The drive motor is fixed on the first air duct housing.

[0035] The gear is connected to the output shaft of the drive motor;

[0036] A rack that meshes with a gear and is rotatably engaged with a second sliding member;

[0037] When the drive motor drives the rack to move through the gear, the rack can move along the opening direction of the second slide rail to drive the second sliding member to move within the second slide rail.

[0038] A third aspect of the present invention provides a cabinet-type air conditioner, which includes the above-described air duct structure or the above-described air duct assembly.

[0039] The air duct structure is located at the bottom of the cabinet air conditioner, and the air outlet in the air duct structure opens to the bottom of the front panel of the cabinet air conditioner, serving as the lower air outlet of the cabinet air conditioner.

[0040] In the above technical solution, the cabinet air conditioner has two operating modes: cooling mode and heating mode.

[0041] When the air conditioner is in cooling mode, the second sliding member is controlled to move between the second slide end B position and the second slide position C, or the second sliding member is controlled to move to the second slide end B position, so that the air guide plate and the first air duct housing form a gradually expanding air guide duct from the air inlet side to the air outlet side.

[0042] When the air conditioner is in heating mode, the second sliding member is controlled to move to the position between the end A of the second slide rail and the position C of the second slide rail, so that the plate of the air guide plate and the first air duct housing form a guide air duct that gradually narrows from the air inlet side to the air outlet side.

[0043] The cabinet air conditioner also includes an electric heating element, which is controlled to turn on when the cabinet air conditioner is running in heating mode.

[0044] In the above technical solution, the cabinet air conditioner also includes an air vent located on the top of the air conditioner;

[0045] The cabinet air conditioner has two operating modes: cooling mode and heating mode. When the cabinet air conditioner is in either cooling or heating mode, the upper and lower air vents are controlled to discharge air simultaneously.

[0046] A fourth aspect of this invention provides a method for controlling the airflow of a cabinet-type air conditioner, which is applied to the aforementioned cabinet-type air conditioner. The method includes:

[0047] The system obtains the operating mode of the cabinet air conditioner and controls the air guide plate's air guide position based on the air conditioner's operating mode to change the airflow direction of the air guide plate.

[0048] In the above technical solution, controlling the air guide plate's airflow position according to the air conditioner's operating mode includes:

[0049] When the air conditioner is running in cooling mode, control the second sliding member to move between the second slide end B position and the second slide position C, or control the second sliding member to move to the second slide end B position, so that the air guide plate and the first air duct housing form a gradually expanding air guide duct from the air inlet side to the air outlet side.

[0050] When the air conditioner is in heating mode, the second sliding member is moved to position A at the end of the second slide rail and position C at the second slide rail, so that the air guide plate and the first air duct housing form a guide air duct that gradually narrows from the air inlet side to the air outlet side.

[0051] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0052] In this embodiment of the invention, a first slide rail and a second slide rail that are perpendicular to each other are provided on the first air duct housing, and a first sliding member that slides in cooperation with the first slide rail and a second sliding member that slides in cooperation with the second slide rail are provided on the air guide plate. In this way, when the first sliding member and the second sliding member slide in their respective slide rails, they can drive the air guide plate to rotate, thereby achieving the air guiding effect. At the same time, the first slide rail and the second slide rail can also limit the first sliding member and the second sliding member, thereby preventing the air guide plate from shaking when guiding air.

[0077] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0078] Currently, the air guide vanes in existing air conditioners are directly driven by motors, which can easily cause the vanes to vibrate. This invention proposes an air duct structure, air duct assembly, a cabinet air conditioner, and an air outlet control method for the cabinet air conditioner. It involves setting a first and a second mutually perpendicular slide rail on a first air duct housing, and setting a first sliding member that slides with the first slide rail and a second sliding member that slides with the second slide rail on the air guide vane. When the first and second sliding members slide within their respective slide rails, they can cause the air guide vane to rotate, thereby achieving the air guiding effect. Simultaneously, the first and second slide rails can also limit the movement of the first and second sliding members, thus preventing the air guide vane from vibrating during air guiding.

[0079] The following is in conjunction with the appendix Figure 1 -Attached Figure 9 The technical solution of this embodiment is described in detail. Unless otherwise specified, the following implementation methods and embodiments can be combined with each other.

[0080] Example

[0081] like Figure 1 As shown, in the existing technology, a large air guide plate is used instead of multiple small air guide plates to improve assembly and increase production efficiency. The driving method is direct motor drive, and the air guide plate rotates in a circular motion around the motor shaft. However, this driving method is not stable, and the air guide plate is prone to shaking when the air volume is large.

[0082] To address the aforementioned problems, the first aspect of the present invention provides a method such as... Figures 2-9 The air duct structure shown includes:

[0083] The first air duct housing 1 has an air inlet and an air outlet 11. The air duct wall of the first air duct housing 1 is provided with a first slide 12 and a second slide 13 that are perpendicular to each other. The first slide 12 extends from the side away from the air outlet 11 to the side closer to the air outlet 11, and the second slide 13 extends from the bottom side of the air outlet 11 to the top side of the air outlet 11.

[0084] The air guide plate 2 is located at the air outlet 11. The air guide plate 2 includes a plate body 21 for guiding airflow and a first sliding member 22 and a second sliding member 23 disposed on the plate body 21. The first sliding member 22 is slidably embedded in the first slide rail 12, and the second sliding member 23 is slidably embedded in the second slide rail 13. When one of the first sliding member 22 and the second sliding member 23 is driven to slide along the slide rail in which it is located, the other can slide synchronously within the slide rail in which it is located.

[0085] The plate 21 is configured such that when the first slider 22 slides along the first slide rail 12 and the second slider 23 slides along the second slide rail 13, the plate can be rotated by the first slider 22 and the second slider 23, thereby changing the flow direction of the plate 21.

[0086] In this embodiment of the invention, a first slide rail 12 and a second slide rail 13 perpendicular to each other are provided on the first air duct housing 1, and a first sliding member 22 that slides in cooperation with the first slide rail 12 and a second sliding member 23 that slides in cooperation with the second slide rail 13 are provided on the plate 21 of the air guide plate 2. In this way, when the first sliding member 22 and the second sliding member 23 slide in their corresponding slide rails, they can drive the air guide plate to rotate, thereby achieving the air guiding effect. At the same time, the first slide rail 12 and the second slide rail 13 can also limit the first sliding member 22 and the second sliding member 23, thereby preventing the air guide plate from shaking when guiding air.

[0087] That is, the air guide plate in this embodiment of the invention adopts a sliding rail design, which can effectively prevent the air guide plate from shaking during air guidance. Figure 8 and Figure 9 As shown, when the air guide plate meets the airflow, the impact force of the airflow acting on the air guide plate can be absorbed by the slide walls of the first slide 12 and the second slide 13, thereby preventing the air guide plate from shaking.

[0088] In any of the above embodiments, such as Figures 2-6 As shown, the first slide rail 12 includes a first slide rail end A121 located near the air outlet 11 and a first slide rail end B122 located away from the air outlet 11 in its extending direction;

[0089] The second slide 13 includes a second slide end A131 near the bottom of the air outlet 11 and a second slide end B132 near the top of the air outlet 11 in its extending direction;

[0090] The projection of the first slide rail 12 onto the second slide rail 13 is located between the end A131 of the second slide rail and the end B132 of the second slide rail.

[0091] When one of the first sliding member 22 and the second sliding member 23 is driven to move from end A to end B along its corresponding slide, the other can move synchronously from end A to end B within its corresponding slide. When one of the first sliding member 22 and the second sliding member 23 is driven to move from end B to end A along its corresponding slide, the other can also move synchronously from end B to end A within its corresponding slide.

[0092] The plate 21 has a closed position for closing the air outlet 11 and an air-guiding position for opening the air outlet 11. When the plate 21 is in the closed position, the first sliding member 22 is located at the end A121 of the first slide rail, and the second sliding member 23 is located at the end A131 of the second slide rail. Figure 4 The states of the first slider 22 and the second slider 23;

[0093] When one of the first sliding member 22 and the second sliding member 23 is driven to move along its corresponding slide rail from end A to end B, the air guide plate can be rotated, so that the plate 21 switches from the closed position to the air guiding position. Figure 5 and Figure 6 The state of the first slider 22 and the second slider 23.

[0094] In this embodiment of the invention, the air guide plate slides from bottom to top when the air outlet 11 is opened for airflow guidance, thereby avoiding vortices inside the air duct and thus preventing any impact on airflow. It should be noted that, as... Figure 1 As shown, in the prior art, when the air guide plate is adjusted to a certain angle, although it can achieve the effect of lifting the air, vortices will be generated inside the air guide plate, which will reduce the air volume.

[0095] Specifically, such as Figure 4 As shown, the second slide 13 includes a second slide position C133 in its extending direction, which is between the second slide end position A131 and the second slide end position B132. The second slide position C133 is at the same height as the first slide 12.

[0096] in

[0097] like Figure 5 As shown, when the second sliding member 23 is located between the end position A131 of the second slide and the position C133 of the second slide, a guide air duct 3 is formed between the plate 21 and the first air duct housing 1, which is gradually narrowed from the air inlet side to the air outlet 11 side.

[0098] like Figure 6 As shown, when the second sliding member 23 is located between the end position B132 of the second slide and the position C133 of the second slide, a guide air duct 3 is formed between the plate 21 and the first air duct housing 1, which is gradually expanding from the air inlet side to the air outlet 11 side.

[0099] It is worth noting that when the second slider 23 is in such a position Figure 5 When the position shown is such that wind gathering effect can be achieved, when the second sliding member 23 is in the position shown as convex 6, typhoon effect can be achieved.

[0100] In any of the above embodiments, such as Figures 2-6 As shown, the first air duct housing 1 includes air duct sidewalls 1a arranged opposite to each other, and air duct bottom wall 1b, air duct top wall 1c and air duct front wall between the two air duct sidewalls. The air duct front wall forms an air outlet. There are two first slide rails 12 and two slide rails 13. Each air duct sidewall 1a is provided with one first slide rail 12 and one second slide rail 13. The first slide rails 12 on the two air duct sidewalls 1a are symmetrically arranged, and the second slide rails 1b on the two air duct sidewalls 1a are also symmetrically arranged.

[0101] The first slide rail 12 and the second slide rail 13 on each sidewall 1a of the air duct are independently set, and the second slide rail 13 is located between the first slide rail 12 and the air outlet 11.

[0102] The plate 21 includes plate sidewalls arranged opposite to each other, each plate sidewall corresponds to an air duct sidewall 1a, and each plate sidewall is provided with a first sliding member 22 and a second sliding member 23.

[0103] The first sliding member 22 is embedded in the first slide rail, and the second sliding member 23 is embedded in the second slide rail.

[0104] like Figure 2 For example, in this embodiment of the invention, the first air duct housing has two slides on both its left and right sides, one horizontal and one vertical. The guide plate 21, which cooperates with these slides, has two sliding members {first sliding member and second sliding member} distributed on its left and right top and bottom ends, respectively, symmetrically arranged. This ensures smooth and consistent movement. The first sliding member 22 at the top cooperates with the horizontally arranged first slide 22, allowing it to slide horizontally. The second sliding member 23 at the bottom passes through the vertically arranged second slide 13, and its horizontal sliding is linked to its vertical movement. When the second sliding member 23 moves upward along the second slide 13, it can drive the bottom end of the guide plate 21 upward. Simultaneously, the first sliding member 22 at the top slides backward along the horizontally arranged first slide 22, thereby causing the plate 21 to flip and open the air outlet 11. After the air outlet 11 is opened, as shown in the schematic diagram... Figure 5 and 6 As shown. Preferably, the first sliding member 22 and the second sliding member 23 are rotating shafts disposed on the peripheral wall of the plate 21 and rotatably or fixedly engaged with the peripheral wall of the plate 21.

[0105] In any of the above embodiments, such as Figure 5 As shown, the bottom wall 1b of the air duct includes an outer bottom wall 1b1 and an inner bottom wall 1b2. The inner bottom wall 1b2 is constructed as an upwardly extending inclined wall from the air inlet side to the air outlet side, and the upward inclination angle α of the inner bottom wall is between 3° and 10°.

[0106] When the second sliding member 23 moves to the end position B132 of the second slide, the plate 21 is parallel to the bottom wall 1b2 of the air duct.

[0107] Specifically, when the aforementioned air duct structure is installed at the bottom of the cabinet unit, in cooling mode, by setting the bottom wall 1b2 of the air duct to be tilted upwards, both the airflow guiding effect and the upward airflow can be achieved, while also increasing the air delivery distance. This avoids the risk of dust blowing directly onto the bottom surface, reducing the risk of after-sales complaints. Furthermore, when the panel 21 is opened to its maximum extent and is parallel to the bottom wall 1b2 of the air duct, the air lifting effect can be optimized. Figure 6 As shown.

[0108] Furthermore, such as Figure 5 As shown, the top wall 1c of the air duct includes an outer top wall 1c1 and an inner top wall 1c2 of the air duct.

[0109] The maximum distance from the first slide rail 12 to the top wall 1c2 of the air duct is d1, and the maximum distance from the first slide rail 1c2 to the bottom wall 1b2 of the air duct is d2, where d1 < d2.

[0110] Preferably, Figure 5 As shown, OA<d1<2OA, thus preventing the top A of the plate 21 from colliding with the inner top wall B of the air duct when the plate 21 rotates. d-10<d2≤d, thus ensuring that the bottom E of the plate 21 can be higher than the top F, so as to achieve the air lifting effect. The bottom E of the plate 21 is shown.

[0111] When the air guide plate 2 opens the air outlet to guide the airflow, since the first sliding member 22 on the plate 21 is located in the first slide rail 12 and the first slide rail 12 is close to the top wall 1c2 of the air duct, the distance between the side of the air guide plate near the air inlet of the air duct and the top of the air duct is always very small, regardless of the position of the air guide plate when the air outlet is opened. Therefore, most of the airflow can be avoided from accumulating in the space between the air guide plate and the top of the air duct, thereby avoiding affecting the airflow of the air duct.

[0112] In any of the above embodiments, such as Figures 5-9 As shown, the air duct structure also includes:

[0113] The second air duct housing 4 and the connecting air duct housing 5 are fluidly connected to the first air duct housing 1 through the connecting air duct housing 5. The interior of the second air duct housing 4 is constructed to form a second air supply duct extending in a second direction, and the interior of the first air duct housing 1 is constructed to form a first air supply duct extending in a first direction. The second direction is different from the first direction.

[0114] The connecting air duct shell 5 is provided with a flow guiding structure 51, which is used to guide the airflow flowing in the second direction in the second air duct shell 4 to the first air duct shell 1 in the first direction.

[0115] Preferably, the first air duct housing 1, the connecting air duct housing 5, and the second air duct housing 4 are integrally formed.

[0116] In this embodiment of the invention, by providing a flow guiding structure 51 in the connecting air duct housing 5, the airflow can be prevented from converging between the air guide plate and the first air duct housing 1 and the inner top wall 1c2 of the air duct when the airflow flows from the second air duct housing 4 to the first air duct housing 1, thereby avoiding the generation of eddies.

[0117] A second aspect of the present invention also provides an air duct assembly, which includes a drive mechanism and the air duct structure described above;

[0118] The drive mechanism is used to drive at least one of the first slider 22 and the second slider 23 to move within its corresponding slide.

[0119] Specifically, the drive mechanism includes:

[0120] A drive motor 6 is fixed on the first air duct housing 1; preferably, the drive motor 6 is a stepper motor.

[0121] Gear 7 is connected to the output shaft end of drive motor 6;

[0122] Rack 8 meshes with gear 7 and rotates together with second sliding member 23.

[0123] When the drive motor 6 drives the rack 8 to move via the gear 7, the rack 8 can move along the opening direction of the second slide 23 to drive the second sliding member 23 to move within the second slide 13.

[0124] Specifically, such as Figures 5-9 As shown, when the drive motor 6 rotates, it drives the gear 7 to rotate. The gear 7 meshes with the rack 8, causing the bottom end of the air guide plate 2 to move upward. At the same time, the top rotating shaft slides backward in the horizontal direction, thereby opening the air guide plate 2.

[0125] It is worth noting that in some embodiments not shown, other types of drive mechanisms can also be used to drive the air guide plate 2, such as electric push rods or hydraulic cylinders.

[0126] A third aspect of the present invention also provides a cabinet-type air conditioner, which includes the above-described air duct structure or the above-described air duct assembly.

[0127] The air duct structure is located at the bottom of the cabinet air conditioner, and the air outlet in the air duct structure opens to the bottom of the front panel of the cabinet air conditioner, serving as the lower air outlet of the cabinet air conditioner.

[0128] Specifically, cabinet air conditioners have two operating modes: cooling mode and heating mode.

[0129] When the air conditioner is in cooling mode, the second sliding member is controlled to move between the second slide end B position and the second slide position C, or the second sliding member is controlled to move to the second slide end B position, so that the air guide plate and the first air duct housing form a gradually expanding air guide duct from the air inlet side to the air outlet side.

[0130] When the air conditioner is in heating mode, the second sliding member is controlled to move to the position between the end A of the second slide rail and the position C of the second slide rail, so that the plate of the air guide plate and the first air duct housing form a guide air duct that gradually narrows from the air inlet side to the air outlet side.

[0131] The cabinet air conditioner also includes an electric heating element, which is controlled to turn on when the cabinet air conditioner is running in heating mode.

[0132] More specifically, in cooling mode, to improve the risk of dust blowing caused by the rapid airflow touching the ground and reduce the risk of after-sales complaints, the bottom surface of the inner air duct and the bottom surface of the air outlet frame of this invention are designed to be inclined, forming a certain angle with the horizontal direction. This achieves a guiding effect, directing the airflow upwards and increasing the air delivery distance. This angle can be within the range of 3 to 10 degrees. Figure 9 As shown, the air guide plate needs to be opened to its maximum angle at this time, that is, after opening, the air guide plate is parallel to the bottom plane of the air outlet frame, so that the air lifting effect can reach the best state.

[0133] More specifically, in heating mode, the opening angle of the adjustable air guide plate should be lower than the top height (i.e., the second sliding member should be between the end position A131 of the second slide rail and the position C133 of the second slide rail), so that it forms a certain angle with the bottom surface 1b2 of the air duct. This angle should be less than 90° and can be maintained between 60° and 85°. By reducing the air outlet area, a concentrating effect can be achieved, thereby increasing the air delivery distance of the downward air outlet and also achieving a heating downward floating effect, so that the indoor temperature rises rapidly. Figure 8 As shown.

[0134] In some implementations, the cabinet air conditioner also includes an air vent located on the top of the air conditioner;

[0135] The cabinet air conditioner has two operating modes: cooling mode and heating mode. When the cabinet air conditioner is in either cooling or heating mode, the upper and lower air vents are controlled to discharge air simultaneously.

[0136] That is, the cabinet air conditioner in the embodiments of the present invention is a device that can achieve simultaneous cooling or heating of the upper and lower parts.

[0137] like Figure 10 As shown, a fourth aspect of the present invention also provides a method for controlling the air outlet of a cabinet air conditioner. This method is applied to the aforementioned cabinet air conditioner, and the air outlet control method includes:

[0138] The system obtains the operating mode of the cabinet air conditioner and controls the air guide plate's air guide position based on the air conditioner's operating mode to change the airflow direction of the air guide plate.

[0139] Specifically, the air guide vane's position is controlled according to the air conditioner's operating mode, including:

[0140] When the air conditioner is running in cooling mode, control the second sliding member to move between the second slide end B position and the second slide position C, or control the second sliding member to move to the second slide end B position, so that the air guide plate and the first air duct housing form a gradually expanding air guide duct from the air inlet side to the air outlet side.

[0141] When the air conditioner is in heating mode, the second sliding member is moved to position A at the end of the second slide rail and position C at the second slide rail, so that the air guide plate and the first air duct housing form a guide air duct that gradually narrows from the air inlet side to the air outlet side.

[0142] More specifically, users can send commands to the air conditioner via remote control based on their usage, and the air conditioner controller will turn on the lower air outlet according to the user's command to determine whether the air conditioner is currently in cooling or heating mode.

[0143] When the cooling mode is activated, the drive motor begins to rotate. When the second sliding member 23 within the second slide rail 13 reaches its top position, the air guide plate 2 opens to its maximum angle, meaning the air guide plate 2 is parallel to the bottom wall 1b2 of the first air duct housing 1, with an included angle of 0 degrees. Figure 9 As shown, the drive motor stops rotating, and the cooling mode continues to operate at this time;

[0144] When the heating mode is activated, the drive motor begins to rotate. When the air guide plate 2 rotates to an angle of 60° to 85° with the bottom wall 1b2 of the air duct (the specific angle can be set according to user requirements), such as... Figure 8 As shown, the motor stops rotating at this time, and the heating mode continues to operate.
