Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air guide mechanism, an air conditioner and a control method thereof. Background Art

[0002] The air conditioner in the related art controls the air output by swinging the air guide plate up and down and the air guide blades left and right. The air volume is relatively concentrated in the air supply area and the wind force is relatively strong, which easily makes the user feel that cold or hot air is directly blown, and the user's comfort is poor. Summary of the Invention

[0003] The problem that this application solves is that users easily feel the direct airflow, which leads to a poor user experience.

[0004] To solve the above problems, on the first aspect, the present application provides an air guide mechanism, which is used to be set at the air outlet of the air conditioner to adjust the air outlet, including an outer air guide plate and an air guide assembly, the outer air guide plate has an air guide surface facing the air supply path, the air guide assembly is connected to the outer air guide plate, and is located on the side facing the air guide surface; the air guide assembly includes a spiral air guide plate and a first driving member, the spiral air guide plate extends spirally around a preset axis, and the first driving member is used to drive the spiral air guide plate to rotate around the preset axis.

[0005] In the air guide mechanism of the embodiment of the present application, an air guide component is provided on one side of the air guide surface of the outer air guide plate, and the first driving member of the air guide member can drive the spiral air guide plate to rotate, thereby cutting the airflow on the air supply path, breaking up the strong flow streams, forming a softer airflow, reducing the direct blowing feeling brought to the user by the airflow, and thereby improving the user experience.

[0006] In an optional embodiment, the outer air deflector is strip-shaped and has a length direction and a width direction, with the predetermined axis extending along the length direction of the outer air deflector. In some embodiments, such as when the air conditioner is a wall-mounted indoor unit, the air outlet may be elongated. Therefore, the outer air deflector may be configured as an elongated strip, with the spiral air deflector extending in the same direction as the outer air deflector to better cooperate with the air outlet and cut the airflow delivered from the air outlet.

[0007] In an optional embodiment, two connecting portions are convexly provided on the wind guide surface of the outer wind guide plate, the two connecting portions are spaced apart in the extension direction of the preset axis, and the wind guide assembly is connected to the two connecting portions.

[0008] In an optional embodiment, the air guide assembly further includes a spiral air guide plate extending vertically along a shaft, the axis of the shaft coinciding with a preset axis, and a spiral air guide plate extending spirally around the shaft. One end of the shaft is rotatably connected to one of the connecting portions, and the other end of the shaft is in transmission connection with a first drive member provided on the other connecting portion. This embodiment fixes the relative position of the outer air guide plate and the air guide assembly by providing two connecting portions, and allows the spiral assembly to rotate freely relative to the outer air guide plate. By providing a shaft to support the spiral air guide plate, the stability of the spiral air guide plate is improved, and the spiral air guide plate is not easily deformed or damaged by stress.

[0009] In an optional embodiment, the spiral air deflector is connected to the shaft body via multiple spaced connection points. Connecting to the shaft body via multiple connection points can not only maintain the relative stability of the shaft body and the spiral air deflector, but also reduce connection costs, reduce the weight of the air deflector assembly, and reduce wind resistance to a certain extent.

[0010] In an optional embodiment, a mounting groove is provided on the connecting portion, and the first driving member is disposed in the mounting groove.

[0011] In an optional embodiment, the air guide mechanism further includes a second drive member, which is in driving connection with the connecting portion and is configured to drive the outer air guide plate and the air guide assembly to move relative to the air outlet. By providing the second drive member, the entire air guide mechanism can be moved on the air conditioner, thereby adjusting the air supply mode.

[0012] In an optional embodiment, the spiral air guide plate is provided with air guide holes and / or protrusions. By providing the air guide holes or protrusions, the airflow passing through the surface of the spiral air guide plate can be further divided, broken up, and dispersed, thereby making the overall airflow softer and improving the user experience.

[0013] In an optional embodiment, the spiral air guide plate has different pitches in the extension direction of the preset axis. Since the airflow may be unevenly distributed before reaching the air guide mechanism, the spiral air guide plate can also be set with uneven pitches to adapt to the uneven flow field.

[0014] In an optional embodiment, the pitch of the spiral air guide gradually decreases from its ends to the middle. Since the air outlet may have strong airflow in the middle and weak airflow on the sides, setting the pitch of the spiral air guide in the middle to be smaller than the pitch of the ends can better cut and break up the strong airflow in the middle.

[0015] In an optional embodiment, the pitch of the end portion of the spiral air guide plate is 40-45 mm; and the minimum pitch of the middle portion of the spiral air guide plate is 30-35 mm.

[0016] In an optional embodiment, the spiral air guide plate includes a large pitch section and a small pitch section, and the pitch of the large pitch section is greater than the pitch of the small pitch section. In addition to setting the pitch to be gradual, the spiral air guide plate can also be segmented to set the pitch as in this embodiment.

[0017] In an alternative embodiment, the spiral air guide includes two large-pitch segments and one small-pitch segment, with the two large-pitch segments positioned at either end of the small-pitch segment. Similarly, since the air outlet may have strong airflow in the middle and weaker airflow on the sides, placing the small-pitch segment in the middle of the spiral air guide and the two large-pitch segments at either end of the spiral air guide can better cut and fragment the strong airflow in the middle.

[0018] In an optional embodiment, the spiral air guide plate includes a plurality of large-pitch segments and a plurality of small-pitch segments, and the plurality of large-pitch segments and the plurality of small-pitch segments are alternately arranged.

[0019] In an optional embodiment, the ratio of the total length of the large-pitch segment to the total length of the small-pitch segment is 0.8 to 1.2. Maintaining the difference in the total length of the large-pitch segment and the small-pitch segment within a certain range can avoid excessive differences in wind speed at the air outlet and achieve the effect of balancing the wind force at the air outlet.

[0020] In a second aspect, the present application provides an air conditioner comprising a frame and an air guide mechanism according to any one of the aforementioned embodiments, wherein the frame forms an air outlet, and the air guide mechanism is arranged at the air outlet to regulate the airflow delivered from the air outlet.

[0021] In an optional embodiment, the air guide mechanism is movably connected to the frame, and the air guide mechanism has a first position and a second position relative to the air outlet;

[0022] When the air guide mechanism is in the first position, the air outlet is opened and the spiral air guide plate is in the air supply path;

[0023] When the air guide mechanism is located at the second position, the air outlet is opened, and the spiral air guide plate is not located in or partially located in the air supply path.

[0024] In this embodiment, the air guide mechanism is movably mounted on the frame, and its position can be adjusted to achieve different air guide effects. When the air guide mechanism is in the first position, the spiral air guide plate is positioned in the air supply path, cutting and breaking up strong air streams, softening the airflow and preventing the user from feeling directly blown by the airflow. When the air guide mechanism is in the second position, the airflow is blocked by the spiral air guide plate, reducing the cutting effect, and the wind force is relatively strong, which can quickly adjust the temperature of the target area and meet the user's urgent need for hot or cold air.

[0025] In an optional embodiment, the air guide mechanism is rotatably connected to the frame, and when the air guide mechanism is located in the second position, the outer air guide plate and the air guide assembly are both located below the air outlet.

[0026] In a third aspect, the present application provides a method for controlling an air conditioner, which is applied to the air conditioner of the aforementioned embodiment. The control method includes:

[0027] Determine the wind mode according to the user's instruction, wherein the wind mode includes soft wind mode and strong wind mode;

[0028] When the wind outlet mode is determined to be the soft wind mode, the wind guide mechanism is controlled to move to the first position, and the first driving member is controlled to drive the spiral wind guide plate to rotate. When the wind outlet mode is determined to be the strong wind mode, the wind guide mechanism is controlled to move to the second position.

[0029] In this embodiment, the air conditioner can adjust the position and state of the air guide mechanism according to the user's instructions, thereby achieving air discharge in a soft wind mode or a strong wind mode. Different modes can meet different needs of users.

[0030] In an optional embodiment, the air outlet mode further includes a weak wind mode, and the control method further includes:

[0031] When it is determined that the air outlet mode is the weak wind mode, the air guide mechanism is controlled to move to the first position and the spiral air guide plate does not rotate.

[0032] In this embodiment, the air outlet mode also includes a weak air mode. In this mode, the airflow is blocked and cut by the spiral air guide, and the intensity of the air delivered to the user is lower than that in the strong air mode. However, since the spiral air guide does not rotate, its ability to cut and break up the airflow is weakened, so the air delivery intensity is stronger than that in the soft air mode. By setting the weak air mode, users can meet more air delivery needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The air conditioners in the related art mainly adjust the direction of the air outlet through the air guide mechanism, and the air supply method is relatively simple. For example, the air outlet of the indoor wall-mounted air conditioner mainly relies on the up and down swinging of the air guide plate and the left and right swinging of the air guide blades to control the air outlet direction. However, when the air guide mechanism blows air in a certain direction and the fan power is large, the hot and cold air will hit the human body surface with a large momentum, and people will feel the "direct blowing feeling" brought by the strong wind. In some cases, this direct blowing feeling will cause discomfort to the user and may even easily cause a cold. Therefore, the air supply method of the air conditioner in the related art is prone to direct blowing, which reduces the user experience. Structurally, the air guide plate and the sweeping blades of the traditional air conditioner are separated, and the air sent out by the air conditioner cannot be cut to reduce the wind force, which causes the user to feel a direct blowing feeling.

[0045] In order to improve the problem in the above-mentioned related technologies that the air flow of the air conditioner will directly blow the user when it supplies air, resulting in a poor user experience, the embodiment of the present application provides an air guide mechanism and an air conditioner equipped with the air guide mechanism. By cutting and breaking the air flow delivered from the air outlet, the final air output is softer, which makes it less likely for the user to have a direct blowing feeling, thereby improving the user's user experience.

[0046] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] Figure 1 This is a structural diagram of an air conditioner 010 in one embodiment of the present application. Figure 1 As shown, in the embodiment of the present application, the air conditioner 010 is a wall-mounted air conditioner indoor unit, which includes a frame 100 and an air guide mechanism 200 arranged on the frame 100. Of course, the air conditioner 010 also includes Figure 1 Other necessary components not shown in the figure, such as heat exchange assembly 300, fan 400, etc. (see Figure 8 、 Figure 9 The frame 100 forms an air duct and an air outlet 101 connecting the air duct, and the air guide mechanism 200 is provided at the air outlet 101 to adjust the air flow sent out from the air outlet 101 .

[0048] Figure 2 This is a schematic diagram of an air guide mechanism 200 in an embodiment of the present application at a first viewing angle; Figure 3 This is a schematic diagram of the air guide mechanism 200 in an embodiment of the present application at a second viewing angle; Figure 4 This is an exploded view of the air guide mechanism 200 in one embodiment of the present application. Figures 1 to 4 The air guide mechanism 200 provided in the embodiment of the present application includes an outer air guide plate 210 and an air guide assembly 220. The outer air guide plate 210 has an air guide surface 211 facing the air supply path. The air guide assembly 220 is connected to the outer air guide plate 210 and is located on the side facing the air guide surface 211.

[0049] In this embodiment, the air supply path refers to the path through which the air flow flows after being sent out from the air outlet 101. The air guide surface 211 of the outer air guide plate 210 faces the air supply path, and can play a certain guiding role in the air flow sent out from the air outlet 101. The air guide component 220 is located on the side facing the air guide surface 211, and can extend into the air supply path to adjust the air flow.

[0050] Furthermore, the air guide mechanism 200 also includes a second driving member 230, which is used to drive the outer air guide plate 210 and the air guide assembly 220 to move relative to the air outlet 101. By providing the second driving member 230, the entire air guide mechanism 200 can be moved on the air conditioner 010, thereby adjusting the air supply mode. In this embodiment, the second driving member 230 can drive the air guide mechanism 200 to rotate relative to the frame 100 to open or close the air outlet 101. When the air outlet 101 is closed, the outer air guide plate 210 blocks the air outlet 101, and the air guide assembly 220 is located inside the air conditioner 010, providing better protection and preventing external impurities from entering the air conditioner 010. The second driving member 230 can also control the degree of opening of the air outlet 101.

[0051] In this embodiment, the air outlet 101 is long and narrow. When the air conditioner 010 is normally mounted on a wall, the air outlet 101 extends horizontally. The outer air guide plate 210 is also strip-shaped, thereby guiding the airflow from the air outlet 101. Furthermore, when the air conditioner is shut down, the outer air guide plate 210 effectively blocks the air outlet 101. Furthermore, to achieve a better airflow guidance effect, the outer air guide plate 210 may have a certain curvature.

[0052] In this embodiment, two connecting portions 212 are protruding from the air guide surface 211 of the outer air guide plate 210. The two connecting portions 212 are spaced apart in the direction of extension of the predetermined axis. The air guide assembly 220 is connected to the two connecting portions 212 and is located between the two connecting portions 212. The connecting portion 212 is rotatably connected to the frame 100 of the air conditioner 010, so that the air guide mechanism 200 as a whole can rotate relative to the frame 100. In this embodiment, the connecting portion 212 extends into the air outlet 101 and connects to the frame 100. To prevent the air guide mechanism 200 from interfering with the lower edge of the air outlet 101 when the air outlet 101 is opened, the connecting portion 212 is curved, forming a recessed portion to avoid the lower edge of the air outlet 101.

[0053] In this embodiment, the air guide assembly 220 includes a spiral air guide plate 221 and a first driving member 225. The spiral air guide plate 221 extends spirally around a preset axis, and the first driving member 225 is used to drive the spiral air guide plate 221 to rotate around the preset axis. In this embodiment, the preset axis is a virtual line, which can be used to represent the position and rotation axis of the spiral air guide plate 221. Since the air guide assembly 220 is arranged on the side of the air guide surface 211 of the outer air guide plate 210, the spiral air guide plate 221 can be in the air supply path when the air outlet 101 is opened. The first driving member 225 of the air guide assembly 220 drives the spiral air guide plate 221 to rotate, thereby cutting the airflow on the air supply path, breaking up the strong flow, forming a softer airflow, reducing the direct blowing feeling brought to the user by the airflow, and thus improving the user experience. It can be understood that the cutting, breaking up and blocking effects of the air guide assembly 220 on the smooth flow stream can destroy the flow stream and generate more turbulence in multiple local areas, thereby preventing the air flow from directly impacting the area where the user is located with a large momentum.

[0054] In this embodiment, the air guide assembly 220 further includes a spiral air guide plate 221 extending vertically from the outer side of the shaft 223 along a shaft body 223, the axis of which coincides with a predetermined axis. The spiral air guide plate 221 extends spirally around the shaft 223, one end of the shaft 223 being rotatably connected to one of the connecting portions 212, and the other end of the shaft 223 being drivingly connected to a first driving member 225 provided on the other connecting portion 212. In this embodiment, the two connecting portions 212 are provided to fix the relative position of the outer air guide plate 210 and the air guide assembly 220, while allowing the spiral assembly to rotate freely relative to the outer air guide plate 210. The provision of the shaft 223 to support the spiral air guide plate 221 improves the stability of the spiral air guide plate 221, making it less susceptible to deformation or damage due to stress.

[0055] The shape of the spiral air guide plate 221 in this embodiment can be viewed as the shape of the space swept by a generatrix rotating around the outer circumference of the shaft body 223 and simultaneously moving along the extension direction of the shaft body 223. During the movement, one end of the generatrix remains connected to the surface of the shaft body 223 and perpendicular to the shaft body 223. Of course, in other optional embodiments, the generatrix of the spiral air guide plate 221 may not be perpendicular to the shaft body 223, but may form an acute angle or an obtuse angle.

[0056] In this embodiment, one of the two connecting parts 212 is provided with a mounting groove 213, and the first driving member 225 is arranged in the mounting groove 213, so that the stability of the first driving member 225 is better guaranteed. The other connecting part 212 is provided with a hole structure, which can be rotatably connected to the end of the shaft body 223. In order to reduce the rotational damping of the shaft body 223, the end of the shaft body 223 that is not connected to the first driving member 225 is rotatably matched with the hole structure on the connecting part 212 through a bearing 224. Of course, in other optional embodiments, a first driving member 225 can also be provided on each of the two connecting parts 212, and the two driving members rotate synchronously to realize the rotation of the shaft body 223 and the spiral air guide plate 221.

[0057] In this embodiment, the extension direction of the preset axis (i.e., the overall extension direction of the spiral air guide plate 221 and the extension direction of the shaft 223) is consistent with the extension direction of the outer air guide plate 210, so as to better cooperate with the air outlet 101 and cut the airflow delivered by the air outlet 101.

[0058] In an alternative embodiment, the spiral air guide plate 221 is connected to the shaft 223 at multiple spaced connection points. This not only maintains the relative stability of the shaft 223 and the spiral air guide plate 221, but also reduces connection costs, reduces the weight of the air guide assembly 220, and reduces wind resistance to a certain extent. Specifically, welding can be used at multiple connection points, or the spiral air guide plate 221 and the shaft 223 can be integrally formed.

[0059] As shown in the figure, an air guide hole 222 is provided on the spiral air guide plate 221. By setting the air guide hole 222, when the air flow passes through the surface of the spiral air guide plate 221, part of it will pass through the air guide hole 222, and part of it will continue to flow along the surface of the spiral air guide plate 221. Therefore, the flow streams are divided, broken and dispersed, making the overall air flow softer, which is conducive to improving the user experience.

[0060] It should be understood that in addition to the air guide holes 222, the spiral air guide plate 221 may also be provided with protrusions (not shown). The protrusions can separate and block the airflow passing through the surface of the spiral air guide plate 221, thereby also making the overall airflow softer. In an optional embodiment, the spiral air guide plate 221 may be provided with both air guide holes 222 and protrusions.

[0061] In an optional embodiment, the spiral air guide plate 221 has different pitches in the extension direction of the preset axis. Since the airflow may be unevenly distributed before reaching the air guide mechanism 200, the spiral air guide plate 221 can also be set with uneven pitches to adapt to the uneven flow field.

[0062] like Figure 2 As shown, in this embodiment, the spiral air guide plate 221 includes a large pitch segment (segment L1 in the figure) and a small pitch segment (segment L2 in the figure), and the pitch of the large pitch segment is greater than the pitch of the small pitch segment. Specifically, the spiral air guide plate 221 includes two large pitch segments and one small pitch segment, and the two large pitch segments are arranged at both ends of the small pitch segment. Since the air outlet 101 may have a strong air outlet in the middle and weak air outlet on both sides, the small pitch segment is set in the middle of the spiral air guide plate 221, and the two large pitch segments are set at both ends of the spiral air guide plate 221, which can better cut and break the strong airflow in the middle, so that the air outlet that finally passes through the air guide mechanism 200 is more uniform as a whole.

[0063] Furthermore, the ratio of the total length of the large-pitch segment to the total length of the small-pitch segment can be set to 0.8 to 1.2. Keeping the total length difference between the large-pitch segment and the small-pitch segment within a certain range can avoid excessive difference in wind speed at the air outlet 101 and achieve the effect of balancing the wind force at the air outlet 101.

[0064] It should be understood that the arrangement of the large pitch segment and the small pitch segment of the spiral air guide plate 221 is not limited to the above-mentioned arrangement. For example, the spiral air guide plate 221 may also include multiple large pitch segments and multiple small pitch segments, and the multiple large pitch segments and the multiple small pitch segments are arranged alternately. In addition to setting the pitch of the spiral air guide plate 221 by segmentation, the pitch may also be set to be gradual. For example, the pitch of the spiral air guide plate 221 gradually decreases from its two ends to the middle. The reason for the arrangement is the same as that of the present embodiment, and such an arrangement is also to be able to better cut and crush the strong airflow in the middle of the air outlet 101.

[0065] Optionally, the pitch of the ends of the spiral air guide plate 221 is 40-45 mm; the minimum pitch of the middle portion of the spiral air guide plate 221 is 30-35 mm; or the pitch of the large pitch section is 40-45 mm, and the pitch of the small pitch section is 30-35 mm. Setting the pitch within this range has a better effect on cutting the airflow.

[0066] Figure 5 FIG. 1 is a block diagram of the air conditioner 010 in one embodiment of the present application. Figure 5 As shown, air conditioner 010 further includes a controller 600 and a human-machine interface device 500. The human-machine interface device 500, the first driver 225, the second driver 230, and the fan 400 are all electrically connected to the controller 600. The controller 600 can receive user commands or send information to the user through the human-machine interface device 500. It can also control the first driver 225 to rotate the spiral air guide plate 221 and the second driver 230 to open or close the air outlet 101 of the air conditioner 010. The human-machine interface device 500 can include a keyboard, a touch screen, an infrared receiver, etc.; the first driver 225 and the second driver 230 can be stepper motors.

[0067] In this embodiment, the air guide mechanism 200 has a first position and a second position relative to the air outlet 101; when the air guide mechanism 200 is in the first position, the air outlet 101 is opened, and the spiral air guide plate 221 is in the air supply path; when the air guide mechanism 200 is in the second position, the air outlet 101 is opened, and the spiral air guide plate 221 is not in or partially in the air supply path. Figure 6 This is a schematic diagram of an embodiment of the present application in which the air guide mechanism 200 is located in the first position; Figure 7 This is a schematic diagram of an embodiment of the present application when the air guide mechanism 200 is located in the second position; Figure 8 This is a cross-sectional view of the air guide mechanism 200 in one embodiment of the present application when it is located at the first position; Figure 9 This is a cross-sectional view of the air guide mechanism 200 in one embodiment of the present application when it is in the second position. Figures 6 to 9As shown, in this embodiment, by movably arranging the air guide mechanism 200 on the frame 100 , different air guide effects can be achieved by adjusting the position of the air guide mechanism 200 . Figure 8 and Figure 9 The hollow arrow in represents the air supply path. When the air guide mechanism 200 is in the first position, the spiral air guide plate 221 can be in the air supply path, cutting and breaking the strong flow streams to soften the airflow and prevent the user from feeling directly blown by the airflow; when the air guide mechanism 200 is in the second position, the airflow is blocked by the spiral air guide plate 221, and the cutting effect is reduced. The wind force is relatively strong and can quickly adjust the temperature of the target area to meet the user's urgent need for hot or cold air. In other words, when the air guide mechanism 200 is in the first position and the second position, the opening degree of the air outlet 101 is different. When it is in the second position, the air outlet 101 is opened to a greater extent. Optionally, when the air guide mechanism 200 is in the second position, the outer air guide plate 210 and the air guide assembly 220 are both located below the air outlet 101. Figure 9 As shown, at this time, the air guide mechanism 200 hardly directly interferes with the airflow delivered from the air outlet 101.

[0068] Since the air conditioner 010 provided in the embodiment of the present application has the air guide mechanism 200 capable of moving relative to the frame 100 to adjust the state of the air flow sent out from the air outlet 101, the embodiment of the present application also provides a control method for an air conditioner. Figure 10 Flowchart of the control method of the air conditioner in the embodiment of the present application. Figure 10 As shown, the control method of the air conditioner includes:

[0069] Step S100: determining a wind mode according to a user instruction, wherein the wind mode includes a soft wind mode and a strong wind mode.

[0070] Taking the air conditioner 010 provided in the embodiment of the present application as an example, the controller 600 receives a command sent by the user through the human-computer interaction device 500, which includes an air flow mode. The air conditioner 010 can have multiple air flow modes. In the embodiment of the present application, at least a soft wind mode and a strong wind mode are included. The soft wind mode produces a gentle wind sensation, which is less likely to cause the user to feel a direct airflow. The strong wind mode is used to meet the user's needs to deliver strong air to the target area.

[0071] Step S200, when it is determined that the air outlet mode is the soft wind mode, the air guide mechanism is controlled to move to the first position, and the first driving member is controlled to drive the spiral air guide plate to rotate. When it is determined that the air outlet mode is the strong wind mode, the air guide mechanism is controlled to move to the second position.

[0072] Taking the air conditioner 010 provided in the embodiment of the present application as an example, after the controller 600 determines the air outlet mode selected by the user, it controls the first driving member 225 and the second driving member 230 to perform corresponding actions according to the determined air outlet mode. Optionally, the rotation angle of the second driving member 230 determines the rotation angle of the entire air guide mechanism 200, and the size of the angle corresponds to the air outlet mode. The corresponding relationship can be pre-stored for future use. For example, the corresponding rotation angle of the second driving member 230 in the soft wind mode (which can be the position relative to the air guide mechanism 200 closing the air outlet 101) is A, and the corresponding rotation angle of the second driving member 230 in the strong wind mode is B, and angle B is greater than angle A. After determining the air outlet mode, the angle that the second driving member 230 needs to rotate can be determined based on the corresponding relationship between the air outlet mode and the rotation angle of the second driving member 230, thereby controlling the second driving member 230 to drive the air guide mechanism 200 to move to the corresponding position. In this embodiment, the air conditioner 010 can adjust the state of the air guide mechanism 200 according to the user's instructions, so that the air can be discharged in a soft wind mode, a strong wind mode, or a strong wind mode. Different modes can meet different user needs. In the strong wind mode, the spiral air guide plate 221 can be kept from rotating to save energy.

[0073] Furthermore, the wind outlet mode may also include a weak wind mode. In this case, the control method further includes: when it is determined that the wind outlet mode is the weak wind mode, controlling the wind guide mechanism to move to the first position and the spiral wind guide plate does not rotate.

[0074] When users need a certain wind feeling but don't want an overly strong wind, they can choose the weak wind mode. In this mode, the airflow is blocked and cut by the spiral wind guide plate 221, and the intensity of the airflow when it reaches the user will be lower than that in the strong wind mode. However, since the spiral wind guide plate 221 does not rotate and only relies on its blocking function and the separation function of the air guide hole 222, its ability to cut and break up the air flow is weakened, so the air output intensity is stronger than that in the soft wind mode. By setting the weak wind mode, users can meet more air supply needs.

[0075] In addition, the air conditioner control method may further include controlling the second driving member 230 to drive the air guide mechanism 200 to close the air outlet 101 after receiving a shutdown command, thereby protecting the air guide assembly 220 and preventing impurities from entering the air conditioner.

[0076] In summary, in the air guide mechanism of the air conditioner according to the embodiment of the present application, an air guide assembly is provided on one side of the air guide surface of the outer air guide plate, and the first driving member of the air guide member can drive the spiral air guide plate to rotate, thereby cutting the airflow on the air supply path, breaking up the strong airflow, forming a softer airflow, reducing the direct blowing feeling brought to the user by the airflow, and thus improving the user's experience. The control method of the air conditioner provided in the embodiment of the present application can adjust the position and state of the air guide mechanism according to the user's instructions, thereby achieving air discharge in soft wind mode or strong wind mode. Different modes can meet different needs of users, thereby improving the user's experience.

[0077] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims.
