Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an air guide device, an air conditioner, a control method, an apparatus, and a storage medium thereof. Background Technology

[0002] Currently available air conditioners, such as ducted air conditioners and central air conditioners, have a single structural form for their air guide plates, and the size of the air guide plates remains unchanged. This results in limitations in the function of the air guide plates. If the width of the air guide plate is too small, it will be difficult for the air guide plate to direct hot air to the ground in heating mode. If the width of the air guide plate is too large, the excessive extension distance of the air guide plate in cooling mode will cause condensation at the extended end, affecting its use. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the objective of embodiments of the present invention is to provide an air guiding device, an air conditioner, a control method, an apparatus, and a storage medium thereof, to adjust the air guiding mode of the air guiding device according to the operating mode of the air conditioner, thereby enhancing its applicability.

[0004] According to a first aspect of the present invention, an air guiding device includes:

[0005] The front frame is equipped with an air outlet;

[0006] The first air guide strip is rotatably disposed at the air outlet around the first rotation axis;

[0007] A rotating arm is positioned at the air outlet, rotating around a second rotation axis.

[0008] At least one second air guide strip is rotatably mounted on the rotating arm about a third rotation axis, and the second air guide strip and the first air guide strip are arranged sequentially along a first direction;

[0009] A drive assembly is configured to drive the first air guide bar, the rotating arm, and the second air guide bar to rotate.

[0010] Wherein, the first rotation axis, the second rotation axis and the third rotation axis are all parallel to the second direction, and the second direction is perpendicular to the first direction.

[0011] According to the first aspect of the present invention, the air guiding device has at least the following advantages: by rotatably mounting the second air guide strip to the rotating arm, the driving component can drive the first and second air guide strips to rotate around their own rotation axes, while the rotating arm remains stationary, making the first and second air guide strips independent air guide plates. These air guide plates have a smaller width, suitable for guiding airflow when the air conditioner is in cooling mode, preventing condensation. Alternatively, the driving component can drive the first air guide strip and the rotating arm to rotate around the same rotation axis, with the second air guide strip fixed relative to the rotating arm and rotating with it, so that the first air guide strip, the second air guide strip, and the rotating arm combine to form an air guide plate. This air guide plate has a larger width, suitable for guiding airflow when the air conditioner is in heating mode, directing hot air to the ground for ease of use. Therefore, the state of the first and second air guide strips can be adjusted according to the operating mode of the air conditioner, enhancing its applicability.

[0012] According to some embodiments of the present invention, the air guiding device has a first air guiding mode. When the air guiding device is in the first air guiding mode, the air guiding surface of the first air guiding strip is parallel to the air guiding surface of the second air guiding strip, and the air guiding angle is greater than [missing information].

[0013] According to some embodiments of the present invention, the rotating arm is provided with an air guiding surface, and the air guiding device has a second air guiding mode. When the air guiding device is in the second air guiding mode, the air guiding surface of the rotating arm, the air guiding surface of the first air guiding strip, and the air guiding surface of the second air guiding strip are coplanar, and the air guiding angle is greater than 0°.

[0014] According to some embodiments of the present invention, the first rotation axis and the second rotation axis coincide.

[0015] According to some embodiments of the present invention, the face frame is provided with a mounting portion, and the first air guide strip is provided with a connecting portion, wherein the connecting portion is rotatably engaged with the mounting portion.

[0016] According to some embodiments of the present invention, one of the mounting portion and the connecting portion is provided with a shaft portion and the other is provided with a shaft hole, the shaft portion extends along the second direction and the shaft portion is rotatably engaged with the shaft hole.

[0017] According to some embodiments of the present invention, the drive assembly includes a first motor, a second motor and at least one third motor. The first motor is connected to the first air guide and drives the first air guide to rotate. The second motor is connected to the rotating arm and drives the rotating arm to rotate. The third motor is connected to the second air guide in a one-to-one correspondence and drives the second air guide to rotate.

[0018] According to some embodiments of the present invention, the drive assembly includes a fourth motor, a fifth motor, and a transmission component. The transmission component is connected to the first air guide and the second air guide. The fourth motor is adapted to drive the first air guide and the second air guide to rotate synchronously. The fifth motor is connected to the rotating arm to drive the rotating arm to rotate.

[0019] According to some embodiments of the present invention, the air guiding device includes a plurality of second air guiding strips, wherein the first air guiding strip and the plurality of second air guiding strips are arranged sequentially along the first direction.

[0020] An air conditioner according to a second aspect of the present invention includes the air guide device described in the first aspect of the present invention.

[0021] According to the second aspect of the present invention, the air conditioner has at least the following beneficial effects: Because the air conditioner employs the aforementioned air guiding device, which rotatably mounts the second air guide strip to the rotating arm, when the air conditioner is in cooling mode, the drive assembly can drive the first and second air guide strips to rotate around their respective rotation axes, while the rotating arm remains stationary, making the first and second air guide strips independent air guide plates. These air guide plates have a small width to prevent condensation. When the air conditioner is in heating mode, the drive assembly can drive the first air guide strip and the rotating arm to rotate around the same rotation axis, while the second air guide strip is fixed relative to the rotating arm and rotates with the rotating arm, so that the first, second, and rotating arm combine to form an air guide plate. This air guide plate has a larger width to direct hot air to the ground, facilitating use. Therefore, the state of the first and second air guide strips can be adjusted according to the air conditioner's operating mode, enhancing its applicability.

[0022] The control method according to a third aspect of the present invention is applied to the air conditioner of the second aspect of the present invention.

[0023] The control method includes the following steps:

[0024] Obtain the operating mode of the air conditioner;

[0025] The operating status of the air guide device is controlled according to the operating mode.

[0026] According to the control method of the third aspect of the present invention, at least the following beneficial effects are achieved: The air guide device, by rotatably mounting the second air guide strip to the rotating arm, allows the control drive assembly to drive the first and second air guide strips to rotate around their respective rotation axes when the air conditioner is in cooling mode, while the rotating arm remains stationary. This makes the first and second air guide strips independent air guide plates with a relatively small width to prevent condensation. When the air conditioner is in heating mode, the control drive assembly drives the first air guide strip and the rotating arm to rotate around the same rotation axis. The second air guide strip is fixed relative to the rotating arm and rotates with it, allowing the first, second, and rotating arms to combine into an air guide plate with a larger width to direct hot air to the ground for ease of use. Therefore, the state of the first and second air guide strips can be controlled and adjusted according to the air conditioner's operating mode, enhancing applicability.

[0027] According to some embodiments of the present invention, controlling the operating state of the air guide device according to the operating mode includes:

[0028] If the operating mode is cooling mode, the air guide device is controlled to be in the first air guide mode;

[0029] If the operating mode is heating mode, control the air guide device to be in the second air guide mode;

[0030] In the first air guiding mode, the air guiding surface of the first air guiding strip is parallel to the air guiding surface of the second air guiding strip, and the air guiding angle is greater than 0°.

[0031] The second air guiding mode is that the air guiding surface of the rotating arm, the air guiding surface of the first air guiding strip, and the air guiding surface of the second air guiding strip are coplanar, and the air guiding angle is greater than 0°.

[0032] According to some embodiments of the present invention, the first air guiding mode includes: the first air guiding strip and the second air guiding strip are located at a first preset position or swing within a first preset angle range.

[0033] According to some embodiments of the present invention, the second air guiding mode includes: the first air guide strip, the rotating arm and the second air guide strip are located at a second preset position or swing within a second preset angle range.

[0034] According to some embodiments of the present invention, controlling the operating state of the air guide device according to the operating mode further includes:

[0035] In heating mode, if the air conditioner is in defrost mode, the air guiding angle of the first air guide strip, the rotating arm, and the second air guide strip is controlled to the maximum air guiding angle.

[0036] According to some embodiments of the present invention, controlling the operating state of the air guide device according to the operating mode further includes:

[0037] In heating mode, if the air conditioner is in defrost mode, the air guide device is controlled to switch to the first air guide mode;

[0038] The air guiding angle of the first air guide strip and the second air guide strip is controlled to the maximum air guiding angle.

[0039] A control device according to a fourth aspect of the present invention includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the control method described in the third aspect of the present invention.

[0040] According to a fifth aspect of the present invention, a computer-readable storage medium stores computer-executable instructions for causing a computer to perform the control method described in the third aspect of the present invention.

[0041] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0063] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0064] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0066] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0067] Currently, most air conditioners on the market have a simple air guide structure at the air outlet panel, with a fixed size. These guides are typically either all narrow or all wide. However, both types of guides have limitations in their functionality. With narrow guides, the distance they extend beyond the air outlet panel is small. While this prevents condensation at the extended end in cooling mode, in heating mode, the narrow guides struggle to direct hot air further, making it difficult to direct hot air to the ground. Conversely, with wide guides, the air is directed further. While this makes it easier to direct hot air to the ground in heating mode, in cooling mode, the larger distance the wide guides extend beyond the air outlet panel causes condensation at the extended end, affecting user experience.

[0068] Therefore, referring to Figures 1 to 10 As shown, a first aspect embodiment of the present invention provides an air guiding device that is applied to an air conditioner. For example, the air guiding device is installed at the air outlet of the air conditioner, or the air guiding device is installed at the ceiling opening of a central air conditioner and connected to the air supply duct to guide the air to a target location.

[0069] Reference Figure 1As shown, the air guiding device includes a frame 100, a first air guide strip 200, a rotating arm 300, a second air guide strip 400, and a drive assembly 500. The frame 100 can be installed on the ceiling and positioned at a ceiling opening. The frame 100 is provided with an air outlet 110, which can be rectangular or other shapes. The direction of the shorter side of the rectangular air outlet 110 is defined as the first direction, and the direction of the longer side is defined as the second direction; that is, the first direction and the second direction are perpendicular.

[0070] Reference Figure 1 As shown, it can be understood that the first air guide strip 200, the rotating arm 300, and the second air guide strip 400 can be regarded as an air guiding assembly. The face frame 100 can be equipped with multiple of the above-mentioned air guiding assemblies located at the air outlet 110, and the multiple air guiding assemblies are arranged side by side along the first direction. The number of second air guide strips 400 in each air guiding assembly can be one, two, three or more.

[0071] The connection method between one of the air guide components and the face frame 100 is described below.

[0072] Reference Figure 1 and Figure 6 As shown, it can be understood that the air guiding assembly includes a second air guiding strip 400. The first air guiding strip 200 and the second air guiding strip 400 have the same structure. Both the first air guiding strip 200 and the second air guiding strip 400 are arranged along a second direction, that is, the length direction of the first air guiding strip 200 and the second air guiding strip 400 is parallel to the second direction. The first air guiding strip 200 is arranged sequentially along a first direction. The first air guiding strip 200 is rotatably disposed at the air outlet 110 about a first rotation axis, the first rotation axis being parallel to the second direction. The first air guiding strip 200 is connected to and rotatably engaged with the face frame 100.

[0073] Reference Figure 1 and Figure 6 As shown, the rotating arm 300 is elongated and located at one end of the first air guide 200 along the second direction, with its length parallel to the first direction. The rotating arm 300 is rotatably positioned at the air outlet 110 around a second rotation axis parallel to the second direction. The rotating arm 300 is connected to and rotatably engaged with the face frame 100. The second rotation axis coincides with the first rotation axis. Typically, the length of the rotating arm 300 is the sum of the widths of the first air guide 200 and the second air guide 400 along the first direction.

[0074] Reference Figure 1 and Figure 6 As shown, it can be understood that the second air guide 400 is rotatably mounted on the rotating arm 300 around the third rotation axis, that is, the second air guide 400 is connected to and rotates with the rotating arm 300, and the third rotation axis is parallel to the second direction.

[0075] Reference Figure 4 and Figure 6 As shown, it can be understood that, in order to improve the connection stability and rotation stability of the second air guide 400, one end of the second air guide 400 is rotatably connected to the rotating arm 300, and the other end is hinged to an auxiliary arm 410. The auxiliary arm 410 is arc-shaped and the center of the virtual circle it is in coincides with the second rotation axis. The other end of the auxiliary arm 410 passes through the face frame 100, so that the auxiliary arm 410 provides a rotation fulcrum for the second air guide 400.

[0076] In other embodiments, it is understood that the faceplate 100 is equipped with two rotating arms 300, which are respectively located at both ends of the first air guide 200 along the second direction and are arranged symmetrically, with the rotation axes of the two rotating arms 300 coinciding. The two ends of the second air guide 400 are respectively rotatably connected to the two rotating arms 300 to improve the connection stability and rotation stability of the second air guide 400.

[0077] Reference Figure 6 As shown, the drive assembly 500 includes a first motor 510, a second motor 520, and a third motor 530, wherein the third motor 530 corresponds one-to-one with the second air guide 400. Specifically, the first motor 510 is fixedly mounted on the face frame 100, and the first air guide 200 is connected to the output shaft of the first motor 510. That is, the first air guide 200 is connected to the face frame 100 through the first motor 510, and the center line of the output shaft of the first motor 510 is the first rotation axis, so the first air guide 200 can be driven to rotate by the first motor 510.

[0078] Reference Figure 6 As shown, it can be understood that the second motor 520 is fixedly installed on the face frame 100, and the rotating arm 300 is connected to the output shaft of the second motor 520. That is, the rotating arm 300 is connected to the face frame 100 through the second motor 520, and the center line of the output shaft of the second motor 520 is the second rotation axis, so the rotating arm 300 can be driven to rotate through the second motor 520.

[0079] Reference Figure 6 As shown, it can be understood that the third motor 530 is fixedly installed on the rotating arm 300, and the second air guide 400 is connected to the output shaft of the third motor 530. The center line of the output shaft of the third motor 530 is the third rotation axis, so the second air guide 400 can be driven to rotate relative to the rotating arm 300 by the third motor 530.

[0080] Reference Figure 4As shown, it can be understood that the side of the faceplate 100 facing the interior of the air conditioner or the interior of the air supply duct is defined as the inner side, and the side facing away is defined as the outer side. The first air guide strip 200, the second air guide strip 400 and the rotating arm 300 are all provided with air guiding surfaces on the inner side.

[0081] Reference Figure 1 As shown, it can be understood that in the initial state, that is, when the first air guide strip 200, the second air guide strip 400 and the rotating arm 300 are closed to the air outlet 110, the air guiding surfaces of the first air guide strip 200, the second air guide strip 400 and the rotating arm 300 are coplanar and the air guiding angle is 0°.

[0082] Reference Figure 2 As shown, during operation, i.e., when airflow is required, the airflow guiding device can make the first airflow guide strip 200 and the second airflow guide strip 400 independent airflow guides. Specifically, the second motor 520 is not working, the rotating arm 300 is fixed relative to the face frame 100, the first motor 510 drives the first airflow guide strip 200 to rotate around the first rotation axis, and the third motor 530 drives the second airflow guide strip 400 to rotate around the third rotation axis. This allows the first airflow guide strip 200 and the second airflow guide strip 400 to rotate to the target position where both airflow angles are the target angles and remain stationary, or allows the airflow angles of the first airflow guide strip 200 and the second airflow guide strip 400 to change within a certain angle range, i.e., the first airflow guide strip 200 and the second airflow guide strip 400 oscillate back and forth within a certain range. Regardless of whether the first airflow guide strip 200 and the second airflow guide strip 400 rotate to the target position and remain stationary or oscillate back and forth within a certain range, generally speaking, the airflow guiding surfaces of the first airflow guide strip 200 and the second airflow guide strip 400 are always parallel, which is the first airflow guiding mode of the airflow guiding device. Since the first air guide strip 200 and the second air guide strip 400 are independent air guide plates, each air guide plate has a small width and a small distance extending beyond the outer side of the frame 100. In cooling mode, this can prevent condensation from forming at the ends of the air guide plates and blowing out water droplets, thus avoiding affecting user use. Therefore, the first air guide strip 200 and the second air guide strip 400 in this air guiding mode are suitable for air guiding when the air conditioner is in cooling mode.

[0083] It is understandable that the air guiding angle is the angle θ between the air guiding surface and the outer side of the frame 100, the target angle is the angle preset by the air conditioner or the angle selected or set by the user according to the settings of the air conditioner, and a certain angle range is the angle range preset by the air conditioner or the angle range selected or set by the user according to the settings of the air conditioner.

[0084] Reference Figure 3 and Figure 4As shown, the air guiding device can also combine the first air guide strip 200, the second air guide strip 400, and the rotating arm 300 into an air guide plate for air guiding. Specifically, the first motor 510 drives the first air guide strip 200 to rotate around the first rotation axis, and the second motor 520 drives the rotating arm 300 to rotate around the first rotation axis (the second rotation axis coincides with the first rotation axis). The second air guide strip 400 is fixed relative to the rotating arm 300 and revolves around the first rotation axis with the rotating arm 300. The first air guide strip 200, the second air guide strip 400, and the rotating arm 300 are rotated to a target position where the air guiding angle is the target angle and then fixed, or the air guiding angle of the first air guide strip 200, the second air guide strip 400, and the rotating arm 300 varies within a certain angle range, that is, the first air guide strip 200, the second air guide strip 400, and the rotating arm 300 oscillate back and forth within a certain range. Whether the first air guide slat 200, the second air guide slat 400, and the rotating arm 300 rotate to a fixed target position or swing back and forth within a certain range, generally speaking, the air guiding surfaces of the first air guide slat 200, the second air guide slat 400, and the rotating arm 300 are always coplanar, which is the second air guiding mode of the air guiding device. Since the first air guide slat 200, the second air guide slat 400, and the rotating arm 300 combine to form an air guide plate, and this air guide plate is relatively wide, it easily directs hot air to a farther location, meaning the air guide plate has good long-distance air guiding capability. Furthermore, the air guide plate extends a considerable distance beyond the outer side of the frame 100, making it easy to direct hot air to the ground in heating mode for user convenience. Therefore, the first air guide slat 200, the second air guide slat 400, and the rotating arm 300 in this air guiding mode are suitable for air guiding when the air conditioner is in heating mode.

[0085] Understandably, since the second rotating shaft is coaxial with the first rotating shaft, when the first air guide strip 200, the second air guide strip 400, and the rotating arm 300 are combined into an air guide plate for air guidance, the distance by which the air guide plate extends beyond the outer side of the face frame 100 is maximized, which is beneficial to improving the air guide plate's ability to guide air over long distances. Furthermore, the distance by which the air guide plate extends into the inner side of the face frame 100 is relatively small, reducing the space occupied by the air guide plate within the face frame 100.

[0086] Reference Figure 4 and Figure 5As shown, it can be understood that a rotating structure is provided between the first air guide strip 200 and the face frame 100 to improve the connection stability and rotational stability of the first air guide strip 200. Specifically, the face frame 100 is provided with a mounting part 120, which protrudes towards the air outlet 110. A shaft part 121 is provided on one side of the mounting part 120 along the second direction. The shaft part 121 is cylindrical and extends along the second direction, and the center line of the shaft part 121 coincides with the first rotation axis, that is, the center line of the shaft part 121 coincides with the center line of the output shaft of the first motor 510. Correspondingly, a connecting part 210 is provided on the side of the first air guide strip 200 facing the mounting part 120. The connecting part 210 is a protrusion structure and is provided with a shaft hole 211. The center line of the shaft hole 211 coincides with the center line of the shaft part 121, and the shaft part 121 and the shaft hole 211 are rotatably engaged. Therefore, by inserting the shaft portion 121 into the shaft hole 211, the mounting portion 120 and the connecting portion 210 can be rotatably engaged, that is, the first air guide strip 200 and the face frame 100 can be rotatably engaged, which is convenient for installation. At the same time, the face frame 100 provides a fulcrum for the first air guide strip 200 to rotate stably.

[0087] Reference Figure 5 As shown, it can be understood that multiple rotating structures as described above are provided between the first air guide strip 200 and the face frame 100 along the second direction to further improve rotational stability.

[0088] It is understandable that the positions of the shaft portion 121 and the shaft hole 211 on the mounting portion 120 and the connecting portion 210 can be interchanged, which will not be elaborated here.

[0089] It is understandable that both the mounting part 120 and the connecting part 210 can be provided with through holes, and the mounting part 120 and the connecting part 210 can be rotated and engaged by a rotating shaft passing through the two through holes, which will not be elaborated here.

[0090] Reference Figure 10As shown, in some embodiments, it can be understood that the air guiding assembly includes a plurality of second air guiding strips 400. The first air guiding strip 200 and the plurality of second air guiding strips 400 are arranged sequentially along a first direction. Each second air guiding strip 400 is rotatably mounted on a rotating arm 300, and the rotation axis of each second air guiding strip 400 is parallel to a second direction. The rotating arm 300 is provided with a third motor 530 that is connected to each of the second air guiding strips 400 in a one-to-one correspondence. Therefore, in cooling mode, the first air guiding strip 200 and the plurality of second air guiding strips 400 rotate around their respective rotation axes, while the rotating arm 300 remains stationary to avoid condensation. In heating mode, multiple second air guide strips 400 are fixed relative to the rotating arm 300 and rotate with the rotating arm 300. The first air guide strip 200, the rotating arm 300, and the multiple second air guide strips 400 combine to form an air guide plate, which can further increase the width of the air guide plate and increase the distance the air guide plate extends beyond the outer side of the face frame 100, further improving the long-distance air guiding capability of the air guide plate, thus making it easier to guide hot air to the ground and making it convenient for users to use.

[0091] Reference Figure 7 As shown, in some other embodiments, it is understood that the first motor 510 can be mounted on the rotating arm 300, and the first air guide 200 is connected to the output shaft of the first motor 510, so that the first air guide 200 can be mounted on the rotating arm 300 through the first motor 510 without being connected to the face frame 100. In this case, the second rotation axis and the first rotation axis may not coincide. In cooling mode, the rotating arm 300 is stationary, and the first air guide 200 and the second air guide 400 rotate around their respective rotation axes to avoid condensation. In heating mode, both the first air guide 200 and the second air guide 400 are stationary relative to the rotating arm 300, and the rotating arm 300 rotates around the second rotation axis. The first air guide 200 and the second air guide 400 then rotate with the rotating arm 300 around the second rotation axis, so that the first air guide 200, the rotating arm 300, and the second air guide 400 combine to form an air guide plate to direct hot air to the ground.

[0092] Reference Figure 8As shown, in some other embodiments, it can be understood that the drive assembly 500 includes a fourth motor 540, a fifth motor 550, and a transmission component 560. The first air guide 200 is rotatably connected to the face frame 100 but not to the rotating arm 300. The second air guide 400 is rotatably connected to the rotating arm 300 via a rotating shaft. The transmission component 560 can be a transmission arm. Both ends of the transmission component 560 are hinged to the first air guide 200 and the second air guide 400, respectively. The hinge axes at both ends of the transmission component 560 do not coincide with the first rotation axis and the third rotation axis, and the distance between the hinge axes at both ends of the transmission component 560 is equal to the distance between the first rotation axis and the third rotation axis. The fourth motor 540 is mounted on the face frame 100, and the first air guide 200 is connected to the output shaft of the fourth motor 540. Therefore, the fourth motor 540 can drive the first air guide 200 to rotate, and under the action of the transmission arm, the second air guide 400 rotates synchronously with the first air guide 200. The fifth motor 550 is mounted on the faceplate 100, and the rotating arm 300 is connected to the output shaft of the fifth motor 550. Therefore, the fifth motor 550 can drive the rotating arm 300 to rotate. At this time, the second rotation axis coincides with the first rotation axis. This drive assembly 500 can reduce the number of motors and reduce costs.

[0093] Reference Figure 8 As shown, in cooling mode, the fifth motor 550 is not operating, the rotating arm 300 is fixed relative to the face frame 100, and the fourth motor 540, in conjunction with the transmission arm, drives the first air guide 200 and the second air guide 400 to rotate synchronously around their respective rotation axes to prevent condensation. In heating mode, the fourth motor 540, in conjunction with the transmission arm, drives the first air guide 200 and the second air guide 400 to rotate synchronously. Simultaneously, the fifth motor 550 drives the rotating arm 300 to rotate around the first rotation axis (the second rotation axis coincides with the first rotation axis), and the second air guide 400 simultaneously revolves around the first rotation axis along with the rotating arm 300. Therefore, the first air guide 200, the rotating arm 300, and the second air guide 400 can be combined to form an air guide plate to direct hot air to the ground.

[0094] Reference Figure 9As shown, in some embodiments, it is understood that the fourth motor 540 can be mounted on the rotating arm 300, and the first air guide 200 is connected to the output shaft of the fourth motor 540, so that the first air guide 200 can be mounted on the rotating arm 300 through the fourth motor 540 without being connected to the face frame 100. In this case, the second rotation axis and the first rotation axis may not coincide. In cooling mode, the rotating arm 300 is different, and the fourth motor 540, in conjunction with the transmission arm, drives the first air guide 200 and the second air guide 400 to rotate synchronously around their respective rotation axes to avoid condensation. In heating mode, the first air guide 200 and the second air guide 400 are both stationary relative to the rotating arm 300, and the fifth motor 550 drives the rotating arm 300 to rotate around the second rotation axis. The first air guide 200 and the second air guide 400 then rotate with the rotating arm 300 around the second rotation axis, so that the first air guide 200, the rotating arm 300, and the second air guide 400 combine to form an air guide plate to direct hot air to the ground.

[0095] A second aspect of the present invention provides an air conditioner, such as a central air conditioner or a ducted air conditioner, wherein the air outlet of the air conditioner is equipped with an air guiding device according to any of the above embodiments.

[0096] Since the air conditioner includes the air guiding device of any of the above embodiments, it has all the beneficial effects of the air guiding device of the above embodiments, which will not be repeated here.

[0097] refer to Figures 11 to 14 As shown, a third aspect embodiment of the present invention provides a control method applied to the air conditioner shown in the above embodiments. The structure or components of the air conditioner have been described in detail in the above embodiments and will not be repeated here.

[0098] The control method is illustrated below with specific examples.

[0099] Reference Figure 11 As shown, it can be understood that the control method includes, but is not limited to, the following steps:

[0100] Step S100: Obtain the operating mode of the air conditioner.

[0101] It is understandable that an air conditioner's operating modes include at least cooling and heating modes. These modes can be selected automatically by the air conditioner or chosen by the user through an interactive device. This interactive device can be a control panel on the air conditioner, a remote control, a mobile phone, or a tablet—any device that can interact with the air conditioner. For example, if a user selects cooling or heating mode through an interactive device, the air conditioner will then enter the corresponding operating mode.

[0102] Step S200: Control the operating status of the air guide device according to the operating mode.

[0103] Understandably, after the air conditioner enters the corresponding operating mode, the air conditioner controls the air guide device to perform corresponding actions, so that the air guide device is in the corresponding operating state, so that the operating state of the air guide device matches the operating mode of the air conditioner. In the cooling mode, condensation is avoided, and in the heating mode, it is easy to direct hot air to the ground.

[0104] Reference Figure 12 As shown, it can be understood that step S200 includes, but is not limited to, the following steps:

[0105] Step S210: If the operating mode is cooling mode, control the air guide device to be in the first air guide mode.

[0106] Specifically, the second motor 520 is not working, the rotating arm 300 is fixed relative to the face frame 100, the first motor 510 drives the first air guide 200 to rotate around the first rotation axis, and the third motor 530 drives the second air guide 400 to rotate around the third rotation axis, so that the first air guide 200 and the second air guide 400 rotate to the first preset position. The first preset position can be the air guide angle preset by the air conditioner or the position corresponding to the air guide angle selected by the user through the interactive device. At this time, the air guide surface of the first air guide 200 and the air guide surface of the second air guide 400 are parallel. The first air guide 200 and the second air guide 400 are independent air guide plates for air guiding. The width of each air guide plate is small, and the distance of the air guide plate extending out of the face frame 100 is small, which can prevent condensation from forming at the end of the air guide plate and avoid affecting the user's use.

[0107] Understandably, the first air guiding mode also includes oscillating the first air guide strip 200 and the second air guide strip 400 within a first preset angle range. Specifically, the user sets the first preset angle range through an interactive device, and the air conditioner controls the first air guide strip 200 and the second air guide strip 400 to rotate around their respective rotation axes according to the first preset angle range, so that the air guiding angle of the first air guide strip 200 and the second air guide strip 400 continuously changes within the first preset angle range. During this process, the air guiding surfaces of the first air guide strip 200 and the second air guide strip 400 remain parallel. That is to say, the first air guide strip 200 and the second air guide strip 400 oscillate back and forth within the first preset angle range, so as to continuously change the air guiding direction in the cooling mode to avoid direct blowing of cold air.

[0108] Step S220: If the operating mode is heating mode, control the air guide device to be in the second air guide mode.

[0109] Specifically, the first motor 510 drives the first air guide 200 to rotate around the first rotation axis, and the second motor 520 drives the rotating arm 300 to rotate around the first rotation axis (the second rotation axis coincides with the first rotation axis). The second air guide 400 is fixed relative to the rotating arm 300 and revolves with the rotating arm 300 around the first rotation axis, causing the first air guide 200, the second air guide 400, and the rotating arm 300 to rotate to a second preset position. Similarly, the second preset position can be the air guiding angle preset by the air conditioner or determined by the user. At the position corresponding to the air guiding angle selected by the interactive device, the air guiding surfaces of the first air guide strip 200, the second air guide strip 400, and the rotating arm 300 are coplanar. The first air guide strip 200, the second air guide strip 400, and the rotating arm 300 are combined into an air guide plate for air guiding. The air guide plate has a large width, making it easy to guide hot air to a farther position. That is, the air guide plate has good long-distance air guiding capability. In addition, the air guide plate extends a large distance beyond the outer side of the face frame 100, making it easy to guide hot air to the ground for user use.

[0110] Understandably, the second air guiding mode also includes oscillating the first air guide 200, the second air guide 400, and the rotating arm 300 within a second preset angle range. Specifically, the user sets the second preset angle range through an interactive device, and the air conditioner controls the first air guide 200, the second air guide 400, and the rotating arm 300 to rotate around the first rotation axis (the second rotation axis coincides with the first rotation axis) according to the second preset angle range, so that the air guiding angle of the first air guide 200, the second air guide 400, and the rotating arm 300 continuously changes within the second preset angle range. During this process, the air guiding surfaces of the first air guide 200, the second air guide 400, and the rotating arm 300 remain coplanar. That is to say, the air guide plate composed of the first air guide 200, the second air guide 400, and the rotating arm 300 oscillates back and forth within the second preset angle range, so as to continuously change the air guiding direction in the heating mode to avoid direct hot air blowing.

[0111] Reference Figure 13 As shown, it can be understood that step S220 includes, but is not limited to, the following steps:

[0112] Step S221: In heating mode, if the air conditioner is in defrost mode, control the air guiding angle of the first air guide strip, the rotating arm and the second air guide strip to the maximum air guiding angle.

[0113] Understandably, in heating mode, the outdoor unit of the air conditioner is prone to frost buildup. When the air conditioner detects frost on the outdoor unit, it will automatically enter defrost mode. Alternatively, when the user is aware of the frost buildup, they can control the air conditioner to enter defrost mode via an interactive device. In defrost mode, the indoor unit of the air conditioner blows cold air.

[0114] Therefore, in heating mode, when the air conditioner is in defrost mode, the air guide device is in the second air guide mode. In the second air guide mode, the air conditioner further controls the first air guide 200, the second air guide 400 and the rotating arm 300 to rotate to the position where the air guide angle is the maximum air guide angle. The maximum air guide angle is the angle preset by the air conditioner. That is to say, the air guide plate composed of the first air guide 200, the second air guide 400 and the rotating arm 300 is controlled to rotate to the position where the air guide angle is the maximum air guide angle, so that the air guide plate is raised as much as possible, so that the cold air is blown to a place farther away from the indoor unit, avoiding the cold air being blown directly to the user.

[0115] Reference Figure 14 As shown, in some other embodiments, step S210 may also include, but is not limited to, the following steps:

[0116] Step S222: In heating mode, if the air conditioner is in defrost mode, control the air guide device to switch to the first air guide mode.

[0117] Understandably, in heating mode, when the air conditioner is in defrost mode, the air guide device is in the second air guide mode. The air conditioner controls the air guide device to switch to the first air guide mode, that is, the first air guide strip 200 and the second air guide strip 400 are independent air guide plates to guide the air, so that the cold air is not easily directed to the ground, thus avoiding the cold air blowing directly to the user and preventing condensation.

[0118] Step S223: Control the air guiding angle of the first air guide strip and the second air guide strip to the maximum air guiding angle.

[0119] Understandably, in the first air guiding mode, the air conditioner further controls the first air guide slab 200 and the second air guide slab 400 to rotate to the position where the air guiding angle is the maximum air guiding angle. In other words, the independent air guide plates formed by the first air guide slab 200 and the second air guide slab 400 are raised as high as possible, so that the cold air is blown to a place farther away from the indoor unit, avoiding the cold air from blowing directly to the user.

[0120] A fourth aspect of the present invention also provides a control device, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor. The processor and the memory can be connected via a bus or other means.

Furthermore, memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device.

Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The units described as separate components may or may not be physically separate; that is, they may be located in one place or distributed across multiple network units.
