Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The embodiment of the application provides an air duct assembly which is mainly applied to an air conditioner to solve the problems that an air direction adjusting mode of the existing air conditioner is not novel and the air output is affected.

In the embodiment of the present application, as shown in fig. 1, the air duct assembly 100 includes an air duct member 10, the air duct member 10 is an air guiding tube with two open ends, and one end of the air duct member 10 is open to form an air outlet 11, and the other end is an air inlet, so that two ends of the air duct member 10 may also be referred to as an air inlet end 12 and an air outlet end 13, respectively. The size, cross-sectional shape, extension shape, etc. of the air duct member 10 may be adaptively designed according to the installation space in the air conditioner 200, and when the air duct member 10 is installed in the air conditioner 200, the wind wheel 220 for promoting the circulation of indoor air in the air conditioner 200 may be installed in the ventilation duct of the air duct member 10, and thus after the wind wheel 220 is started, the air duct member 10 may be introduced into the air through the air inlet thereof and discharged out through the air outlet 11 thereof.

In order to adjust the air outlet direction at the air outlet 11, in the present application, the air duct assembly 100 further includes a guide fan 20, wherein the guide fan 20 is installed at the air outlet 11 of the air duct member 10, and the guide fan 20 is used for blowing air to the air outlet 11 so as to adjust the air outlet direction at the air outlet 11 by blowing the air to the air outlet 11. Wherein, in order to avoid wind resistance of the guiding fan 20 on the air flow at the air outlet 11, the guiding fan 20 is arranged at the outer side of the air outlet 11 in the circumferential direction; in the axial direction of the air outlet 11 (the axial direction refers to the extending direction of the axis perpendicular to the plane of the air outlet 11), there may be various specific mounting positions of the guide fan 20, for example, the guide fan 20 may be mounted on the side of the air outlet 11 away from the air inlet, and the air flow just flowing out of the air outlet 11 is blown by the guide fan 20; for another example, the rotating shaft of the guiding fan 20 may be disposed corresponding to the edge of the air outlet 11, and the guiding fan 20 blows the air flow that will reach the air outlet 11, pass through the air outlet 11 and just flow out of the air outlet 11; for another example, as shown in fig. 1, the guiding fan 20 is located at a side of the air outlet 11 near the air inlet, and the guiding fan 20 blows an air flow to reach the air outlet 11. In short, the positional relationship between the guide fan 20 and the air outlet 11 in the axial direction of the air outlet 11 may be selected as required, as long as the guide fan 20 can blow the air flow at the air outlet 11.

That is, when the duct assembly 100 of the present application is mounted to the air conditioner 200, the duct member 10 is positioned in the cabinet 210 of the air conditioner 200, and the air outlet 11 of the duct member 10 is positioned on the surface of the cabinet 210 and communicates with the external space (i.e., the indoor space) of the cabinet 210, and the guide fan 20 may be positioned outside the cabinet 210 or inside the cabinet 210. For example, in an embodiment, referring to fig. 1 and 3, the guide fan 20 is disposed on a side wall of the air duct member 10 at the air outlet end 13, that is, both the guide fan 20 and the air duct member 10 are installed in the casing 210 of the air conditioner 200, so that the guide fan 20 is hidden, and the appearance of the air conditioner 200 is more concise and air.

When it should be noted here, the guide fan 20 may be disposed on the inner wall of the air duct member 10 or may be disposed on the outer wall of the air duct member 10, and when the guide fan 20 is disposed on the inner wall of the air duct member 10, in order to avoid wind resistance caused by the air duct member 10 itself to the air flow at the air outlet 11, a groove may be disposed on the air duct member 10 corresponding to the inner wall of the guide fan 20, and the guide fan 20 is disposed in the groove and does not protrude out of the notch of the groove. When the guide fan 20 is disposed on the outer wall of the air duct member 10, as shown in fig. 1, the air vent 14 may be disposed on the air duct member 10 corresponding to the outer wall of the guide fan 20, and the air vent 14 penetrates through the side wall of the air duct member 10 to communicate the inner space and the outer space of the air duct member 10, and the guide fan 20 is disposed corresponding to the air vent 14, so as to blow air to the air duct member 10 and near the air outlet 11. It can be understood that by arranging the ventilation holes 14 on the side wall of the air duct member 10 and arranging the guide fans 20 corresponding to the ventilation openings, the guide fans 20 can suck air from outside the air duct member 10 and blow the air to the air outlet 11 when being started, instead of sucking air in the air duct member 10, so that the situation that the air suction is difficult or insufficient due to the influence of the main flow direction of the air in the air duct member 10 when the guide fans 20 suck air from inside the air duct member 10, and then the air direction adjustment is influenced can be avoided.

It should be further noted that the number and the installation direction of the guide fans 20 may be selected according to the actually required air outlet direction, for example, in an embodiment, at least one side of the air outlet 11 in the length direction is provided with the guide fans 20, and/or at least one side of the air outlet 11 in the width direction is provided with the guide fans 20. Specifically, in order to more clearly illustrate the technical solution of the present application, please refer to fig. 5 to 14, the present description takes the left side and the right side of the air outlet 11 along the length direction, and takes the upper side and the lower side of the air outlet 11 along the width direction as examples.

When the guiding fans 20 are arranged, one guiding fan 20 can be arranged, and the one guiding fan 20 is arranged on one of the upper side, the lower side, the left side and the right side of the air outlet 11, at this time, the one guiding fan 20 can at least realize wind guiding in one direction and small-range wind sweeping including the direction, for example, the one guiding fan 20 is arranged on the right side of the air outlet 11, and after the one guiding fan 20 is started, the air flow at the air outlet 11 can be blown to flow to the left side of the air outlet 11, so that the left wind guiding is realized; on the basis of this, the rotation speed of the one guide fan 20 can be further controlled to be repeatedly switched between gradually increasing and gradually decreasing, so that the air flow at the air outlet 11 can be deflected back and forth between the forward blowing state and the state of deflecting to the left blowing, and the air flow is in a left and right blowing state as a whole. Therefore, the structure in which only one guide fan 20 is provided is suitable for the air conditioner 200 that does not need much in the air outlet direction (for example, the air conditioner 200 is installed at a corner, and then the air is not required to sweep the wall side), and the cost is required to be controlled.

Alternatively, two or more guide fans 20 may be provided, and two or more guide fans 20 may be provided on any two of the upper side, the lower side, the left side and the right side of the air outlet 11, respectively, for example, as shown in fig. 1, one guide fan 20 may be provided on each of the left side and the right side of the air outlet 11, and in order to enable wind blown by the guide fans 20 to blow an air flow at any position in the width direction of the air outlet 11, the diameter of each of the guide fans 20 on the left and right sides may be adapted to the width of the air outlet 11, i.e., the diameter of the guide fan 20 may be the same as the width of the air outlet 11, or may be slightly smaller than the width of the air outlet 11. It can be understood that, at this time, the air conditioner 200 can at least blow air to the air outlet 11 through the right guiding fan 20 to guide air to the left, or blow air to the air outlet 11 through the right guiding fan 20 to guide air to the right, or blow air to the left and right through the left and right guiding fans 20 alternately to sweep air, or blow air to the air outlet 11 through the two guiding fans 20 to blow air to each other to achieve soft air.

Also, if two or more guide fans 20 are provided at the upper and lower sides of the air outlet 11, respectively, the air conditioner 200 can at least achieve upward air guide, downward air guide, upward and downward air sweeping, and gentle air. Alternatively, the guiding fans 20 may be disposed on the upper side and the right side of the air outlet 11, and the guiding fans 20 may not be disposed on the lower side and the left side of the air outlet 11, so that the air conditioner 200 is at least capable of guiding air downward, guiding air leftward and downward (the guiding fans 20 on the upper side and the right side blow simultaneously), sweeping air upward and downward with the position of the air conditioner 200 being the highest air outlet point, and sweeping air leftward and rightward with the position of the air conditioner being the rightmost air outlet point.

In summary, in practical application, the specific number and installation positions of the guide fans 20 may be set according to the actual air-out requirement, and the specific implementation principle may refer to the embodiments described above, which will not be described herein. Here, when the guide fan 20 is disposed at one side of the air outlet 11 in the width direction, and the diameter of the guide fan 20 is much smaller than the length of the air outlet 11, in order to blow the air flow at any position in the length direction at the air outlet 11, referring to fig. 9, a plurality of guide fans 20 may be provided, and the plurality of guide fans 20 may be arranged along the length direction of the air outlet 11.

In addition, it should be noted that the guiding fan 20 may be fixedly installed, that is, the blowing direction of the guiding fan 20 remains unchanged, for example, after the guiding fan 20 on the right side is installed, the blowing direction of the guiding fan 20 always faces the left side of the air outlet 11, so that the installation structure and process of the guiding fan 20 may be simplified. Of course, the guide fan 20 may also be movably mounted, such as optionally, in an embodiment, referring to fig. 1 and 2, the guide fan 20 is further connected to the universal mechanism 30 so that the guide fan 20 can rotate about the first axis 21 and the second axis 22; wherein the first axis 21 extends parallel to the axial direction of the air outlet 11; when the guide fan 20 is located at one side of the air outlet 11 in the length direction, the second axis 22 extends parallel to the width direction of the air outlet 11; when the guide fan 20 is located at one side of the air outlet 11 in the width direction, the second axis 22 extends parallel to the length direction of the air outlet 11.

Specifically, after the guide fan 20 is coupled to the gimbals mechanism 30, the gimbals mechanism 30 is coupled to the duct member 10 or other components of the air conditioner 200 (such as a housing, or a dedicated mounting frame, etc.), the gimbals mechanism 30 may be designed with reference to an existing gimbals structure, i.e., as shown in fig. 2, the guide fan 20 is rotatably mounted to the gimbals mechanism 30, the gimbals mechanism 30 is rotatably mounted to the duct member 10 or the housing 210 of the air conditioner 200, and one of the rotation axis of the guide fan 20 and the rotation axis of the gimbals mechanism 30 is the first axis 21, and the other is the second axis 22. For example, when the guide fan 20 is located at one side of the air outlet 11 in the length direction, the rotation axis of the guide fan 20 is the first axis 21, and the rotation axis of the universal mechanism 30 is the second axis 22; when the guide fan 20 is located in the longitudinal direction of the air outlet 11, the rotation axis of the guide fan 20 is the second axis 22, and the rotation axis of the universal mechanism 30 is the first axis 21.

It will be appreciated that by having the pilot fan 20 also connected to the gimbal mechanism 30, the direction of the air blowing of the pilot fan 20 may be made adjustable, which in turn may allow for better control of the angle of the air blowing of the pilot fan 20, and may allow for more directional air guiding with a smaller number of pilot fans 20. For example, as shown in fig. 5 to 8, a guiding fan 20 is disposed on each of the left and right sides of the air outlet 11, and each guiding fan 20 is mounted on the air duct member 10 or other components of the air conditioner 200 through the universal mechanism 30, and at this time, each guiding fan 20 can rotate around the first axis 21, so that the blowing direction can face the upper side or the lower side of the air outlet 11, and further, the guiding fans 20 are not required to be disposed on the upper side and the lower side of the air outlet 11, and upward air guiding, downward air guiding, upward and downward air sweeping, and upward and downward bidirectional air guiding can be also realized. For the up and down wind sweeping, please refer to fig. 5 and 6, both the guiding fans 20 can be repeatedly switched between the obliquely upward position and the obliquely downward position; for the up-down bidirectional wind guiding, one of the guiding fans 20 can be blown upwards in an inclined manner, and the other guiding fan 20 is blown downwards in an inclined manner, at this time, under the condition that the total wind output at the wind outlet 11 is unchanged, because of the pressurization and guiding of the guiding fans 20 at the left side and the right side, the air flow at the wind outlet 11 can flow upwards and downwards respectively, so that the wind output range in the up-down direction is enlarged.

Similarly, referring to fig. 10 and 11, if the guide fans 20 are disposed on the upper side and the lower side of the air outlet 11, the guide fans 20 can rotate around the first axis 21 to tilt to the left or right, and further, the guide fans 20 are not required to be disposed on the left side and the right side of the air outlet 11, and the left air guide, the right air guide, the left and right air guide, and the left and right air sweeping can be realized.

In addition, since the guide fan 20 can also rotate around the second axis 22, that is, the blowing direction of the guide fan 20 can be inclined to the front side (i.e., the side toward which the air outlet 11 faces) and the rear side (i.e., the side close to the direction of the incoming air) of the air outlet 11, when the guide fan 20 blows the air flow at the air outlet 11, the guide fan 20 can be inclined to the front side of the air outlet 11 by a certain angle, thereby helping to improve the blowing distance of the air conditioner 200.

In summary, compared with the traditional scheme of arranging the air deflector in the air outlet 11, the air duct assembly 100 provided by the application can realize wind direction adjustment under the condition of not using the air deflector, thereby realizing a brand new wind direction adjustment mode; the guiding fan 20 in the application does not need to be arranged in the air outlet 11 and guides air through the surface of the guiding fan, so that larger wind resistance is not caused to air flow at the air outlet 11 to influence air output, and conversely, the guiding fan 20 in the application blows air to the air flow at the air outlet 11, so that the air output at the air outlet 11 can be ensured more than the scheme of guiding air by an air deflector. In addition, the application can further realize the wind sweeping and the wind softening for the position, the rotating speed, the quantity and the like of the guide fan 20, and further realize the wind sweeping and the wind softening on the basis of not using the wind sweeping blades and the wind softening blades.

As shown in fig. 3, the present application further provides an air conditioner 200, where the air conditioner 200 mainly includes a casing 210 and an air duct assembly 100, and the specific structure of the air duct assembly 100 refers to the above embodiment, where the air duct member 10 in the air duct assembly 100 is installed in the casing 210, the air outlet 11 on the air duct member 10 is located on the surface of the casing 210 and is in communication with the external space of the casing 210, and the wind wheel 220 in the air conditioner 200 may be installed in the air duct of the air duct member 10. Because the present air conditioner 200 adopts all the technical solutions of all the embodiments, it has at least all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

As shown in fig. 4, the present application further provides an air outlet control method, which is applied to the air conditioner 200 described above, and specifically includes:

step S1: acquiring an air supply instruction; the air supply command may be sent by a user through a remote controller, or may be sent by the air conditioner 200 itself intelligently according to actual conditions, for example, when the temperature of a certain side of the room is detected to be higher or lower under the condition that the temperature of each place in the room is required to be uniform, a corresponding command may be sent through an electric control board, so that the temperature of the indoor target position is adjusted by adjusting the air outlet direction.

In this embodiment, the air supply instruction may be generally divided into an air guiding instruction, a wind sweeping instruction and a soft air instruction, where the air guiding instruction may be further divided into an upward air guiding instruction, a downward air guiding instruction, a leftward air guiding instruction, a rightward air guiding instruction, an up-down bidirectional air guiding instruction, a left-right bidirectional air guiding instruction, an up-left air guiding instruction, a down-left air guiding instruction, an up-right air guiding instruction and a down-right air guiding instruction according to a specific air guiding direction. The wind sweeping command can be subdivided into an up-down wind sweeping command and a left-right wind sweeping command according to the specific wind sweeping direction. Of course, in practical application, other air supply instructions may be set according to the actual air supply requirement.

Step S2: determining a target air supply mode corresponding to the air supply instruction from preset air supply modes according to the air supply instruction; specifically, the air supply modes are in one-to-one correspondence with the air supply instructions, so that the air supply modes are correspondingly divided into an air guide mode, an air sweeping mode and a soft air mode, wherein the air guide mode can be further divided into an upward air guide mode, a downward air guide mode, a leftward air guide mode, a rightward air guide mode, an upward and downward air guide mode, a leftward and rightward air guide mode, an upward and leftward air guide mode, a downward and leftward air guide mode, an upward and rightward air guide mode and a downward and rightward air guide mode according to specific air guide directions. The wind sweeping mode can be subdivided into an up-down wind sweeping mode and a left-right wind sweeping mode according to the specific wind sweeping direction.

Any one or more of the above air supply modes may be preset on the air conditioner 200 according to actual needs, and when an air supply command is received, a corresponding target air supply mode may be determined from the above multiple preset air supply modes according to the air supply command.

Step S3: acquiring control information of the guide fan 20 according to the target air supply mode; specifically, since the air outlet direction or type is required to be achieved by blowing air to the air outlet 11 through the guide fan 20, after the target air blowing mode is determined, control information of the guide fan 20 needs to be acquired so as to control the corresponding guide fan 20 to perform a corresponding action according to the control information. The control information mainly includes a target guiding fan 20 that needs to perform a corresponding action, and a specific action that the target guiding fan 20 needs to perform; in practical application, the above multiple air supply modes and the control information of the guide fan 20 may be pre-stored in a one-to-one correspondence, and the corresponding control information may be directly obtained after the target air supply mode is determined.

Step S4: the guiding fan 20 is controlled to switch to a corresponding operation state according to the control information, so that the guiding fan 20 blows air flow at the air outlet 11 to realize the target air supply mode, that is, after the control information corresponding to the target air supply mode is acquired, the guiding fan 20 is directly controlled to adjust the blowing direction, the rotating speed and the like according to the control information, so that the guiding fan 20 blows air flow at the air outlet 11, and the air conditioner 200 can realize the target air supply mode.

In the application, the air supply mode is divided into an air guide mode, a sweeping mode and a soft air mode, and because the air guide mode, the sweeping mode and the soft air mode are respectively three different air supply modes, the control information corresponding to the three air supply modes is also different, and the air guide mode, the sweeping mode and the soft air mode are respectively described below.

1. Wind guiding mode:

in the present application, the control information corresponding to the wind guiding mode includes: at least one target wind guiding direction of the airflow to be guided, identification information of the first target guiding fan 20 to be controlled, and a first target operation state of the first target guiding fan 20; wherein the first target operating state comprises a blowing direction and/or a rotational speed of the first target-guiding fan 20.

Specifically, the air guiding direction may be divided into four basic directions of up, down, left and right, and at least one target air guiding direction of the air flow to be guided is selected or combined among the four basic directions according to the target air supply mode. For example, when the target air supply mode is the upward air guiding mode, the target air guiding direction to be guided of the air flow is upward; when the target air supply mode is an upper left air guide mode, the target air guide direction to be guided of the air flow is left and upward; when the target air supply mode is an up-down bidirectional air guide mode, the target air guide direction to be guided of the air flow is upward and downward. Here, the direction of the air flow indicates the vertical direction and the horizontal direction in the plane of the tuyere 11.

The identification information is information for uniquely identifying the guide fan 20 so as to determine the first target guide fan 20, and may be position information of the guide fan 20, number information set for the guide fan 20, or the like, for example, as shown in fig. 5, the Left and Right sides of the air outlet 11 are respectively provided with the guide fan 20, and at this time, the identification information of the guide fan 20 on the Left side may be L (Left) or number 1, and the guide fan 20 on the Right side may be R (Right) or number 2. Thus, the corresponding guiding fan 20 can be controlled to execute the corresponding action quickly and accurately according to the target air supply mode, for example, when the target air supply mode is the left air guiding mode, the corresponding control information at least comprises the guiding fan 20 with the identification information L, and the guiding fan 20 is the first target guiding fan 20. For example, when the target air supply mode is the left and right air sweeping mode, the corresponding control information at least includes a guide fan 20 with the identification information L and a guide fan 20 with the identification information R, and the two guide fans 20 are the first target guide fan 20.

The first target operation state mainly includes a blowing direction and/or a rotation speed of the first target guide fan 20, for example, as shown in fig. 5, the guide fans 20 are respectively disposed on the left side and the right side of the air outlet 11, and the two guide fans 20 are both mounted on the air duct member 10 or other components of the air conditioner 200 through the universal mechanism 30, and when the target blowing mode is the upward air guiding mode, the first target operation states of the two guide fans 20 are both inclined to the upper side of the air outlet 11 in the blowing direction. Alternatively, as shown in fig. 8, when the target air supply mode is the left and right wind sweeping mode, the first target operation states of both guide fans 20 are the air blowing directions toward the opposite sides, the rotational speed of each guide fan 20 is repeatedly switched between gradually increasing and gradually decreasing, and there is an opposite rotational speed variation tendency between the guide fan 20 on the left side and the guide fan 20 on the right side.

In practical application, the first embodiment, the second embodiment and the third embodiment of the air guiding mode may be arbitrarily combined or split according to needs. For example, the first embodiment and the second embodiment are directly combined, that is, the upper side, the lower side, the left side and the right side of the air outlet 11 are respectively provided with the guide fans 20, and each guide fan 20 is connected with the air duct member 10 or other components of the air conditioner 200 through the universal mechanism 30, and in a certain target air supply mode, the left side and the right side of the guide fans 20 blow according to the first embodiment, and the upper side and the lower side of the guide fans 20 blow according to the second embodiment. For example, in the third embodiment, the fixed guide fans 20 may be disposed only on the upper side and the right side of the air outlet 11, and the rotatable guide fans 20 may be disposed on the lower side and the left side of the air outlet 11, or the guide fans 20 may not be disposed, where in a certain target air supply mode, the upper side and the right side of the guide fans 20 blow according to the third embodiment, and the lower side and the left side of the rotatable guide fans 20 blow according to the second embodiment and the first embodiment, respectively.

In addition, as shown in fig. 7, when the guide fans 20 on the left and right sides are inclined upward and downward, respectively, to achieve vertical bidirectional air guiding, there is a possibility that the length of the air outlet 11 is long, and the air blown by the guide fans 20 cannot reach the middle position of the air outlet 11. Thus, optionally, in an embodiment, the wind guiding mode includes a bidirectional wind guiding mode that guides wind in two opposite directions simultaneously, and the control information corresponding to the bidirectional wind guiding mode includes: the first target wind guiding direction and the second target wind guiding direction of the airflow to be guided, the identification information of the first target guiding fan 20 to be controlled, and the first target running state of the first target guiding fan 20; the first target wind guiding direction and the second target wind guiding direction are opposite, the first target guiding fan 20 includes at least two guiding fans 20 that are opposite, and the first target running state includes at least two guiding fans 20 that are opposite in the first target guiding fan 20 blowing in opposite directions, and repeatedly switching between a position blowing in the first target wind guiding direction and a position blowing in the second target wind guiding direction, respectively.

It can be understood that the air blowing direction of each guiding fan 20 will gradually blow to the air flow at the middle position of the air outlet 11 in the switching process, and along with the continuous rotation of the guiding fans 20, the air flow at the middle position of the air outlet 11 can be brought to the lower side or the upper side, so that more air flows at the air outlet 11 can be blown to be guided up and down in two directions, the situation that the air flow at the middle position of the air outlet 11 is not guided to the upper side or the lower side is avoided, and the air guiding effect is improved.

Specifically, the wind sweeping mode includes an up-down wind sweeping mode and a left-right wind sweeping mode, so that the target wind sweeping direction also includes an up-down wind sweeping direction and a left-right wind sweeping direction, and it is to be noted that when the air supply direction is deflected up and down, the air supply direction can be regarded as up-down wind sweeping, for example, the deflection of the air supply direction between the upper side and the lower side of the air outlet 11 is up-down wind sweeping, and the deflection of the air supply direction between the front side and the lower side (or between the front side and the upper side) of the air outlet 11 is also up-down wind sweeping state; the same applies to the left and right wind sweeping, and will not be described in detail here.

The identification information may be described in the foregoing, and will not be described in detail herein, after the target wind sweeping direction is determined, the second target guiding fan 20 may be determined according to the target wind sweeping direction, for example, when the target wind sweeping direction is above and below the air outlet 11, the second target guiding fan 20 may be rotatable guiding fans 20 on the left and right sides, and at this time, the second target running state includes that the guiding fans 20 on the left and right sides are repeatedly switched between the position of blowing obliquely upwards and the position of blowing obliquely downwards, respectively; alternatively, the second target guiding fans 20 may be guiding fans 20 on the upper and lower sides, and the second target operation state includes that the rotation speeds of the guiding fans 20 on the upper and lower sides are alternately greater than each other, that is, the rotation speed of each guiding fan 20 is repeatedly switched between gradually increasing and gradually decreasing.

Several specific examples are set forth below for the wind-guiding mode.

Embodiment one of the wind sweeping mode:

as shown in fig. 5 and 6, in the present embodiment, one guide fan 20 is provided at each of the left and right sides of the air outlet 11, and each guide fan 20 is connected to the duct member 10 or other components of the air conditioner 200 through the universal mechanism 30.

When the target air supply mode is the up-down wind sweeping mode, please refer to fig. 5 and 6, the air blowing direction of the guide fan 20 is controlled to be repeatedly switched between the upwardly inclined position and the downwardly inclined position.

When the target air supply mode is the left and right wind sweeping mode, please refer to fig. 8, the guiding fans 20 are controlled to blow to opposite sides, and the rotation speed of the guiding fans 20 is controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the guiding fans 20 on the left and right sides are controlled to have opposite speed variation trends.

Second embodiment of wind sweeping mode:

in this embodiment, as shown in fig. 10 and 12, a plurality of guiding fans 20 are respectively disposed on the upper side and the lower side of the air outlet 11, and the guiding fans 20 are all connected with the air duct member 10 or other components of the air conditioner 200 through the universal mechanism 30.

When the target air supply mode is the up-down wind sweeping mode, as shown in fig. 9, the guide fans 20 are controlled to blow on opposite sides, and the rotational speed of the guide fans 20 is controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the guide fans 20 on both upper and lower sides are controlled to have opposite speed variation trends.

When the target air blowing mode is the left and right air sweeping mode, the air blowing direction of the steering fan 20 is controlled to be repeatedly switched between a position inclined to the left and a position inclined to the right in conjunction with fig. 10 and 11.

Third embodiment of wind sweeping mode:

When the target air supply mode is the up-down wind sweeping mode, the rotation speeds of the guide fans 20 on the upper side and the lower side are controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the opposite speed change trend is controlled between the guide fans 20 on the upper side and the lower side.

When the target air supply mode is the left and right wind sweeping mode, the rotation speeds of the guide fans 20 on the left and right sides are controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the guide fans 20 on the left and right sides are controlled to have opposite speed change trends.

Here, in the first, second and third embodiments, since the air is blown to both sides (upper and lower sides or left and right sides) of the air outlet 11, the opposite sides of the air outlet 11 need to be provided with the guide fans 20, and the opposite sides of the guide fans 20 need to have opposite rotational speed variation trends, that is, when the rotational speed of one side of the guide fans 20 is gradually increased, the rotational speed of the opposite side of the guide fans 20 is gradually decreased.

In addition, in practical application, the first, second and third embodiments of the above wind sweeping mode may be changed according to the actual air supply requirement. For example, in the left and right wind sweeping mode of the first or third embodiment, if the right side of the air conditioner 200 is installed against a wall, only the rotation speed of the right side guide fan 20 may be controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the left side guide fan 20 may be turned off. For another example, in the up-down wind sweeping mode of the second or third embodiment, if the installation height of the air conditioner 200 is high without sweeping wind to the upper side of the air outlet 11, only the rotation speed of the upper guide fan 20 may be controlled to be repeatedly switched between gradually increasing and gradually decreasing, and the lower guide fan 20 may be turned off.

3. Soft wind mode:

in the present application, the control information corresponding to the soft wind mode includes: identification information of the third target-guiding fan 20 to be controlled, and a third target operation state of the third target-guiding fan 20; the third target guiding fan 20 includes at least one pair of two guiding fans 20 disposed opposite to each other, and the third target operating state includes any two guiding fans 20 disposed opposite to each other in the third target guiding fan 20 blowing air in opposite directions.

Specifically, in order to change the strong wind at the air outlet 11 into the soft wind, the strong wind needs to be dispersed by blowing the oppositely arranged guide fans 20 in opposite directions, so that the third target guide fan 20 to be controlled at least comprises a pair of two oppositely arranged guide fans 20, for example, the third target guide fan 20 to be controlled may comprise two guide fans 20 on the left and right sides, a plurality of guide fans 20 on the upper and lower sides, or both the guide fans 20 on the left and right sides and a plurality of guide fans 20 on the upper and lower sides.

The third target operation state includes any two opposite directional fans 20 blowing in opposite directions, such as the left and right directional fans 20 blowing in opposite directions, and/or the upper and lower directional fans 20 blowing in opposite directions.

It should be noted that, after the air flow at the air outlet 11 is dispersed into soft air, the flow speed of the soft air is smaller, and the air supply distance of the soft air is further limited, so that in an embodiment, the third target running state further includes that any two guide fans 20 of the third target guide fans 20 that blow in opposite directions are inclined towards the outside of the air outlet 11, for example, as shown in fig. 14, when the air flows in opposite directions, the guide fans 20 on the left and right sides are inclined towards the outside in the axial direction of the air outlet 11, so that a part of the air blown by the guide fans 20 can be dispersed into the air flow at the air outlet 11, and the other part of the air can be blown out of the air outlet 11, and when the soft air is just blown out of the air outlet 11, the left and right sides of the soft air are accompanied with part of the air blown by the guide fans 20, so that the soft air and indoor static air flow can be blocked by the air blown out of the guide fans 20, friction between the soft air and the static air flow is reduced, and the soft air can be blown further, and the air supply distance of the soft air is improved.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to related descriptions of other embodiments. In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
