[0002] With the development of air-conditioning technology, people's demand for air-conditioning functions is not only to have faster cooling and heating speeds, but also to have strict requirements on the air supply comfort of the air conditioner.

[0003] However, existing air conditioners are limited by the shape and space of traditional air conditioners. Existing air conditioners usually supply air by setting a single air guide plate or a same-direction double air guide plate or a reverse double air guide plate. The above-mentioned air guide plates have a common disadvantage that it is difficult to achieve cold air direct blowing protection and up and down distributed air supply.

[0004] In response to the above problems, relevant technologies have begun to gradually develop large sporty air guide plates for air conditioners, which can achieve the functions of preventing cold air from blowing directly and distributing air up and down. However, the large sporty air guide plates require a gear box to drive the air guide plates, which results in higher manufacturing costs than ordinary air guide plates. After the gear box and the connecting rod are coordinated, the motion errors of the entire air guide plate structure will be accumulated, affecting the motion reliability of the entire air guide plate, and further leading to problems such as the air guide plate not closing tightly and movement noise. Summary of the invention

[0005] The embodiments of the present invention provide an air guide plate structure, an air conditioner and an air guide control method, aiming to solve the problem that the existing air conditioner uses a gear box to drive a large air guide plate, resulting in large motion errors that affect the motion reliability of the entire air guide plate.

[0027] See also Figure 1-3 The air guide plate structure is arranged at the air outlet 1 of the air conditioner and is used to guide the air outlet of the air conditioner. The air guide plate structure includes: an outer air guide plate 2, an inner air guide plate 3 and a connecting rod driving assembly;

[0028] The outer air guide plate 2 is rotatably mounted on the lower edge of the air outlet 1 and can be rotatably opened and closed at the air outlet 1;

[0029] The inner air guide plate 3 is rotatably mounted on the upper edge of the air outlet 1 and can be rotatably stored in the inner wall of the upper edge of the air outlet 1 or rotatably unfolded on the lower side of the upper edge of the air outlet 1. When the inner air guide plate 3 is rotatably unfolded on the lower side of the upper edge of the air outlet 1, it cooperates with the outer air guide plate 2 that is rotated and opened to realize downward air supply;

[0030] The connecting rod driving assembly is arranged in the false air outlet area of ​​the air outlet 1 , and the connecting rod driving assembly is movably connected to the inner wall of the outer air guide plate 2 and is used to drive the outer air guide plate 2 to rotate and open and close at the air outlet 1 .

[0031] In this embodiment, the two ends of one side edge (lower edge) of the outer air guide plate 2 are rotatably installed on the two ends of the lower edge of the air outlet 1, so that the rotation axis position of the outer air guide plate 2 remains unchanged, thereby ensuring that the appearance gap of the outer air guide plate 2 is smaller when it is rotated and closed, and the whole machine is more beautiful.

[0032] In some air supply modes, when the air conditioner is in normal cooling working state, the inner air guide plate 3 does not move, and the upper and lower air sweeping can be achieved by controlling the outer air guide plate 2 to rotate up and down; due to the high density of cold air, it is only necessary to control the rotation angle of the outer air guide plate 2 so that the cold air passes through the outer air guide plate 2 and is blown toward the top of the space, thereby achieving a rapid cooling of the temperature in the space. In some air supply modes, when the air conditioner is in normal heating working state, the inner air guide plate 3 rotates outward to the lower side of the upper edge of the air outlet 1, and the outer air guide plate 2 is fully unfolded downward, so that the hot air passes through the outer air guide plate 2 and the inner air guide plate 3 and is blown toward the ground of the space, thereby achieving a rapid heating of the temperature in the space. That is, the present invention can enable the ordinary rotating air guide plate to achieve the comfort air supply function of the air conditioner by setting the inner air guide plate 3 and the outer air guide plate 2.

[0033] In the present embodiment, since the air outlet 1 is generally arranged below the air conditioner, due to the limitations of the internal space and appearance of the air conditioner, there is not enough space at the rotating shaft of the outer air guide plate 2 of the present invention to place the connecting rod drive assembly, and it is not suitable to directly drive the rotating shaft of the air guide plate 2 to control its opening and closing, and the use of the rotating shaft of the outer air guide plate 2 directly to realize the opening and closing process will also cause a large gap between the outer air guide plate 2 and the air outlet 1; therefore, the present invention arranges the driving part of the connecting rod drive assembly in the false air outlet area of ​​the air outlet 1, and movably connects it with the inner side wall of the outer air guide plate 2 through the connecting rod structure, and drives the outer air guide plate 2 to rotate by applying a motion force on the inner side wall of the outer air guide plate 2; the problem that there is no space in the air outlet 1 to arrange the driving part structure of the connecting rod drive assembly, and the connecting rod structure is relatively simple and reliable. Compared with the prior art that uses a gear box assembly, the motion cumulative dimensional tolerance of the connecting rod drive assembly of this embodiment can be ignored, so that the closing effect of the outer air guide plate 2 can be beautiful.

[0034] In one embodiment, the connecting rod drive assembly includes a first drive motor 4, a rotating shaft 5 and a connecting rod 6; the first drive motor 4 is arranged in the false air outlet area of ​​the air conditioner; the rotating shaft 5 is slidably installed on the inner wall of the outer air guide plate 2; one end of the connecting rod 6 is connected to the first drive motor 4, and the other end of the connecting rod 6 is rotatably connected to the rotating shaft 5; the first drive motor 4 is used to drive the connecting rod 6 to rotate up and down and link the rotating shaft 5 to slide on the inner wall of the outer air guide plate 2 to drive the outer air guide plate 2 to rotate up and down.

[0035] In some specific implementations, one end of the connecting rod 6 can be vertically fixedly connected to the output shaft of the first drive motor 4, and the connecting rod 6 can be driven by the first drive motor 4 to rotate along the rotation direction of the outer air guide plate 2. The other end of the connecting rod 6 is rotatably connected to the rotating shaft 5, and the rotating shaft 5 is slidably installed on the inner wall of the outer air guide plate 2 and can slide on the inner wall of the outer air guide plate 2 along the air supply direction; thus, the connecting rod 6 is driven to rotate by the first drive motor 4, and the other end of the connecting rod 6 can drive the rotating shaft 5 to slide on the inner wall of the outer air guide plate 2, so that the outer air guide plate 2 can be linked to rotate to achieve opening and closing at the air outlet 1.

[0036] More specifically, a guide slot 7 is opened on the inner wall of the outer air guide plate 2 along the air supply direction, and the rotating shaft 5 is slidably installed in the guide slot 7; the sliding path of the rotating shaft 5 is limited by the guide slot 7 to achieve stable rotation and opening and closing of the outer air guide plate 2.

[0037] In one embodiment, the air guide plate structure further includes a second drive motor 8 for driving the inner air guide plate 3 to rotate and open; the second drive motor 8 is disposed on the inner side of the upper edge of the air outlet 1, and the output shaft of the second drive motor 8 is coaxially connected with the rotation axis of the inner air guide plate 3. The inner air guide plate 3 is directly driven to rotate by the second drive motor 8, so that the inner air guide plate 3 can be rotated and stored and unfolded for use.

[0038] In one embodiment, the wind guide plate structure further includes a sweeping blade 9, which is disposed in the air outlet 1 and is used to swing left and right to adjust the wind direction. The sweeping blade 9 is adjacent to the outside of the air outlet 1. When the inner wind guide plate 3 rotates, the sweeping blade 9 swings to the left upper limit position or the right upper limit position to avoid the rotation of the inner wind guide plate 3.

[0039] In this embodiment, since the inner air guide plate 3 needs to have sufficient movement space when rotating, but in order to ensure that the left and right air sweeping blades 9 have a better effect, the air sweeping blades 9 need to be arranged adjacent to the air outlet 1, but this design causes the air sweeping blades 9 and the inner air guide plate 3 to conflict and interfere with each other in the rotation space; therefore, this embodiment ensures that the movement of the air sweeping blades 9 and the inner air guide plate 3 is controlled by control logic without changing the existing air duct structure to avoid structural interference.

[0040] Specifically, when the wind sweeping blade 9 swings left and right, when it swings to the left upper limit position or the right upper limit position, the structure of the wind sweeping blade 9 facing the air outlet 1 will retract a little. Utilizing this characteristic, when the inner air guide plate 3 rotates and passes through the wind sweeping blade 9, the current direction of the wind sweeping blade 9 is swung to the left upper limit position or the right upper limit position. At this time, the space for the wind sweeping blade 9 to retract can be avoided by the inner air guide plate 3 so that the inner air guide plate 3 can be turned out.

[0041] An embodiment of the present invention also provides an air conditioner, comprising an air conditioner body 10, a crossflow fan blade 11 and the above-mentioned air guide plate structure, wherein the crossflow fan blade 11 is arranged in the air conditioner body 10 and is used to output airflow to the air outlet 1, and the air guide plate structure is arranged at the air outlet 1 of the air conditioner body 10 and is used to guide the output airflow.

[0042] See also Figure 4 , Figure 4 A schematic diagram of a flow chart of air guide control provided by an embodiment of the present invention;

[0043] like Figure 4 As shown, the method is applied to the above wind guide plate structure, and the method includes steps S401-S402.

[0044] S401, controlling the connecting rod driving assembly to drive the outer air guide plate 2 to rotate and open to a first preset angle, so that the wind direction of the air outlet 1 is facing upward;

[0045] S402, controlling the connecting rod driving assembly to drive the outer air guide plate 2 to rotate and open to a second preset angle, and controlling the inner air guide plate 3 to rotate and unfold to the lower side of the upper edge of the air outlet 1, so that the wind direction of the air outlet 1 is downward.

[0046] During the cold air control process of the present embodiment, when the air conditioner is in normal cooling working state, the inner air guide plate 3 does not move, and the upward and downward sweeping of wind can be achieved by controlling the outer air guide plate 2 to rotate up and down; since the density of cold air is relatively large, it is only necessary to control the rotation angle of the outer air guide plate 2 so that the cold air passes through the outer air guide plate 2 and is blown toward the top of the space, thereby achieving rapid cooling of the temperature in the space.

[0047] During the hot air control process of this embodiment, when the air conditioner is in a normal heating working state, the inner air guide plate 3 rotates outward to the lower side of the upper edge of the air outlet 1, and the outer air guide plate 2 is unfolded downward, so that the hot air can be blown toward the ground of the space through the outer air guide plate 2 and the inner air guide plate 3, and the temperature in the space can be quickly raised. That is, the present invention can enable the ordinary rotating air guide plate to realize the comfortable air supply function of the air conditioner by setting the inner air guide plate 3 and the outer air guide plate 2.

[0048] In one embodiment, the wind guide control method further includes:

[0049] While controlling the inner air guide plate 3 to rotate, the sweeping blade 9 is controlled to rotate along the current swing direction to the left upper limit or the right upper limit and then stop swinging until the current rotation angle of the inner air guide plate 3 is greater than the preset angle, and then the rotation and swinging of the sweeping blade 9 is resumed.

[0050] This embodiment provides a control logic to control the movement of the wind sweeping blade 9 and the inner wind guide plate 3 to avoid the problem of structural interference. Specifically, before controlling the second drive motor 8 to drive the inner wind guide plate 3 to rotate and unfold, first determine whether the wind sweeping blade 9 has swung to the left upper limit or the right upper limit. When it is determined that the wind sweeping blade 9 has swung to the left upper limit or the right upper limit, the swing of the wind sweeping blade 9 is paused, and the second drive motor 8 is controlled to drive the inner wind guide plate 3 to start rotating and unfolding. When the current rotation angle of the inner wind guide plate 3 is greater than the preset angle, the rotation and swing of the wind sweeping blade 9 is resumed, and the inner wind guide plate 3 continues to rotate until it is fully opened.

[0051] In some embodiments, the preset angle may be 30° to 40°.

[0052] In some preferred embodiments, the preset angle may be 35°.
