[0062] Example 1

[0063] like Figures 1 to 21 As shown, the present invention discloses an air guide mechanism with a two-way air guide function, comprising:

[0064] A base 1, an air outlet 2 is arranged on the base 1, and a first end plate 4 and a second end plate 5 are respectively arranged on both sides of the air outlet 2, a first rotating slide groove 41 is arranged on the first end plate 4, and a second rotating slide groove 51 is correspondingly arranged on the second end plate 5, and a first limiting end 411 and a second limiting end 412 are respectively arranged at opposite ends of the first rotating slide groove 41;

[0065] The air guide door 3 is arranged at the air outlet 2 and can perform bidirectional swinging motion relative to the air outlet 2;

[0066] The second driving motor 9 is disposed on the second end plate 5 and is capable of driving the air guide door 3 to move to the first limit end 411 or the second limit end 412;

[0067] The first driving motor 7 is disposed on the first end plate 4 , and can drive the air guide door 3 to swing in both directions relative to the air outlet 2 along the first rotating shaft at the first limiting end 411 or the second rotating shaft at the second limiting end 412 .

[0068] The present application discloses an air guide mechanism with a two-way air guide function, which is achieved by setting two drive motors, a first drive motor 7 and a second drive motor 9, wherein the second drive motor 9 is used to drive the air guide door 3 to switch between a first limit end 411 and a second limit end 412, and the first drive motor 7 is used to drive the air guide door 3 to move toward the outside of the air outlet 2 along the first rotating shaft at the first limit end 411 or the second rotating shaft at the second limit end 412 to open the air outlet 2, thereby achieving different rotation directions and rotation angles of the air guide door 3 under the two working conditions of cooling and heating. Specifically, the first limit end 411 is arranged above the outer side of the second limit end 412, that is, the first rotating shaft is formed above the outer side of the second rotating shaft. Under the cooling condition, the second driving motor 9 can drive the air guide door 3 to move to the first limit end 411, and the first driving motor 7 can drive the air guide door 3 to rotate along the first rotating shaft, and the upper side of the air guide door 3 rotates outward, so that the air outlet 2 under the cooling condition discharges air upward under the action of the air guide door 3; under the heating condition, the second driving motor 9 drives the air guide door 3 to rotate along the first rotating shaft, and the upper side of the air guide door 3 rotates outward. The machine 9 can drive the air guide door 3 to move to the second limit end 412, the first drive motor 7 can drive the air guide door 3 to rotate along the second rotating shaft, and the lower side of the air guide door 3 rotates outward, so that the air outlet 2 can discharge air downward under the action of the air guide door 3 under the heating condition; and because the air guide door 3 rotates along the two rotating shafts under the cooling condition and the heating condition respectively, the air guide plate can be used for different air guide angles under the heating condition and the cooling condition, thereby realizing the double-axis forward and reverse air guidance of the air guide mechanism under different working conditions.

[0069] The air guide mechanism with two-way air guide function described in the present application, through the joint action of the first drive motor and the second drive motor, drives the air guide plate to move toward the outside of the air outlet along the two rotating shafts respectively, so as to realize different wind direction control of the air outlet under cooling condition and heating condition, flexibly control the air outlet area and wind direction, provide a more personalized and comfortable air outlet experience, and improve the adaptability and performance of the system.

[0070] As a preferred example of the present application, the second drive motor 9 is connected to the second rotating shaft 32 of the air guide door 3 through the connecting crank 10, and a rotating bearing 37 is arranged on the outer side of the second rotating shaft 32. The inner ring of the rotating bearing 37 is connected to the second rotating shaft 32 as a whole, and the outer ring of the rotating bearing 37 is connected to the first transmission gear 33 as a whole. A transmission rack 6 is arranged on the second end plate 5 at a position corresponding to the second rotating groove 51, and the first transmission gear 33 is meshed with the transmission rack 6 for transmission.

[0071] The arrangement discloses a mechanism for the air guide door 3 to move between the first rotating shaft and the second rotating shaft, and realizes the switching of the air guide plate between the first rotating shaft and the second rotating shaft by connecting the gear rack with the crank. By setting the rotating bearing 37 on the outer side of the second rotating shaft 32, when the air guide door 3 is driven by the first driving motor 7, the outer ring of the rotating bearing 37 does not rotate, and the inner ring rotates, so that the air guide door 3 is driven to open; when the air guide door 3 is driven by the second driving motor 9 to switch the position, the inner ring does not move, and the outer ring rotates, and then the position switching of the air guide plate is realized by the gear rack transmission structure. The above arrangement structure is ingenious, and the air guide door 3 can flexibly switch the position between the first rotating shaft and the second rotating shaft and ensure the reliability of the swing air guide control by connecting the crank 10, the rotating bearing 37 and the transmission rack 6. The structure is compact and the transmission is reliable, and the position of the air guide door 3 can be flexibly adjusted, thereby controlling the reliable adjustment of the air outlet direction and angle.

[0072] As an example of the present application, the second drive motor 9 includes a second output shaft 901, the connecting crank 10 includes a crank rod 1001, and a motor connection keyway 1002 and a first air guide door connection key 1003 are respectively provided at opposite ends of the crank rod 1001, the motor connection keyway 1002 is connected to the keyway of the second output shaft 901, and the first air guide door connection key 1003 is connected to the keyway of the first connection hole 321 on the second rotating shaft 32. The rotation of the second drive motor 9 is transmitted to the air guide door 3 through the connecting crank 10, thereby realizing precise control of the position and movement of the air guide door 3, so that the air guide door 3 can be accurately adjusted to the shaft position according to the operation mode, thereby accurately adjusting the direction and size of the air outlet to meet different air flow requirements.

[0073] As a preferred example of the present application, the first driving motor 7 is connected to the first rotating shaft 31 of the air guide door 3 through a transmission gear assembly 8, a transmission rack 6 is provided on the first end plate 4 at a position corresponding to the first rotating slide slot 41, and the transmission gear assembly 8 is meshed with the transmission rack 6 for transmission. The air outlet direction and angle of the air guide door 3 are adjusted by providing the transmission gear assembly 8, with small manufacturing tolerance, high dimensional accuracy, and less prone to structural deformation, thereby ensuring the reliability of flexible adjustment of the position of the air guide door 3.

[0074] As a preferred example of the present application, the transmission gear assembly 8 includes a first connecting cover 81, a second connecting cover 82 and a gear assembly 83, wherein the gear assembly 83 includes a driving gear 831, a transmission gear 832 and a driven gear 833, the gear assembly 83 is installed in the second connecting cover 82 and covers the first connecting cover 81, the driving gear 831 is connected to the first output shaft of the first drive motor 7, the driven gear 833 is connected to the keyway of the first rotating shaft 31, and the transmission gear 832 is meshed with the driving gear 831 and the driven gear 833 for transmission. Specifically, as an example of the present application, the second connection cover 82 includes a second accommodating cover plate 821, on which a second connection hole 822 and a first limiting hole 823 are provided, wherein the second connection hole 822 is used to avoid the first output shaft from being connected to the driving gear 831, and the first limiting hole 823 is used to support and limit the rotating shaft of the driven gear 833, and the driving gear 831, the transmission gear 832 and the driven gear 833 are arranged in a meshing state on the second accommodating cover plate 821, and then The second accommodating cover 821 is connected to the first connecting cover 81, and the first connecting cover 81 includes a first accommodating cover 811. A third rotating groove 812 is set at one end of the first accommodating cover 811, and the third rotating groove 812 is set corresponding to the first rotating groove 41. The second air guide door connecting key of the first rotating shaft 31 passes through the third rotating groove 812 and is connected to the keyway of the driven gear 833. The outer teeth of the driven gear 833 can be meshed and connected with the transmission rack 6 on the first end plate 4.

[0075] The setting discloses a specific structure of a transmission gear assembly 8, so that the air guide door 3 can be opened, closed and adjusted in angle as needed, so as to achieve precise adjustment of the air outlet direction and size. At the same time, the middle transmission gear 832 is meshed with the driving gear 831 and the driven gear 833 during use, which has high precision and is less prone to abnormal noise.

Specifically, two third connecting columns 813 are provided on the first accommodating cover plate 811, and the two third connecting columns 813 are arranged on opposite sides of the first drive motor 7.

[0077] As a preferred example of the present application, a first mounting seat 42 is provided on the outer side of the first end plate 4, and a second mounting seat 52 is provided on the outer side of the second end plate 5. The first mounting seat 42 and the second mounting seat 52 are respectively connected to a transmission rack 6, and the transmission rack 6 includes a connecting portion 61 and a gear guide rail 62. The connecting portion 61 is used to connect with the first mounting seat 42 or the second mounting seat 52, and the gear guide rail 62 is used to limit the movement trajectory of the first transmission gear 33 and the driven gear 833. This arrangement further ensures the reliability of the air guide door 3 switching the position of the first rotating shaft and the second rotating shaft along the first rotating slot 41 and the second rotating slot 51 under the action of the second driving motor 9, and ensures the transmission stability and accuracy of the air guide door 3 during the movement. Preferably, a second connecting column 53 is provided on the outer side of the second end plate 5, and the second connecting column 53 is used to install and fix the second driving motor 9.

[0079] This arrangement makes relatively minor changes to the structure of the existing air guide door 3 , reduces mold opening costs, and at the same time ensures the reliability and stability of the air guide door 3 being driven by the first drive motor 7 to change the air outlet direction.

[0080] Example 2

[0081] The present invention also discloses an air conditioner, comprising an air guide mechanism with a two-way air guide function as described in the above-mentioned embodiment 1, wherein the air guide door 3 arranged at the air outlet 2 on the base 1 can be moved by the second drive motor 9 to move the air guide door shaft position, and the air guide door 3 can be driven by the first drive motor 7 to swing forward and reverse. Under heating conditions, the lower side of the air guide door 3 rotates outward, and the rotation angle is [0, α]. Under cooling conditions, the upper side of the air guide door 3 rotates outward, and the rotation angle is [0, β]. The maximum values ​​of α and β are the angles parallel to the wind direction when the air guide door 3 is opened. Fig.19 The α marked in the figure is only for indicating the direction in which the air guide door 3 is opened under the heating condition. Fig.21 The β marked in the figure is only for indicating the direction in which the air guide door 3 opens under the cooling condition.

[0082] The air conditioner described in the present application is designed with an air guide mechanism that can guide air in both directions. The axial movement of the air guide door 3 is controlled by the second drive motor 9, and the angle of rotation of the air guide door 3 relative to the rotating shaft is controlled by the first drive motor 7 in the forward and reverse rotation, thereby controlling the air outlet angle and air outlet direction, so that the air conditioner has the best user experience under different working conditions. The rotating shaft of the air guide door 3 is connected to the motor, thereby realizing reliable drive control of the air guide door 3.

[0083] In the air conditioner of the present invention, the air guide door 3 includes the following working conditions:

[0084] When the air guide door 3 is in the closed state, the first rotating shaft 31 of the air guide door 3 moves to the first limit end 411, and the second driving motor 9 is locked by a program and cannot rotate;

[0085] Under the refrigeration condition, the air guide door 3 moves to the first limit end 411 under the action of the second drive motor 9, and the air guide door 3 rotates under the control of the program under the action of the first drive motor 7, and drives the air guide door 3 to rotate through the transmission gear assembly 8, so that the lower side of the air guide door 3 rotates outward to open;

[0086] In the heating condition, the air guide door 3 moves to the second limit end 412 under the action of the second drive motor 9, and the air guide door 3 rotates under the control of the program under the action of the first drive motor 7, and the air guide door 3 is driven to rotate through the transmission gear assembly 8, so that the upper side of the air guide door 3 is rotated outward to open;

[0087] In the position switching condition, the first drive motor 7 is in a free state, and the first output shaft of the first drive motor 7 can rotate freely with the air guide door 3. The second drive motor 9 is controlled by the program to rotate the second output shaft 901, and the air guide door 3 is driven to rotate by the connecting crank 10. The air guide door 3 switches to another shaft position along the transmission rack 6.

[0088] As a preferred example of the present application, under the cooling condition, it includes five adjustable wind speed gears, namely strong, high, medium, low, and silent. The air intake of the five adjustable wind speed gears decreases in sequence. As the air volume decreases, the air outlet angle of the air guide door 3 gradually increases, and the opening angle of the air guide door 3 gradually decreases. As an example of the present application, under the cooling condition, the air guide door 3 rotates at the first rotating shaft, and the opening angle of the air guide door 3 is A, where:

[0089] The air outlet of the air conditioner is adjusted to a strong wind level, A=α;

[0090] The air outlet of the air conditioner is adjusted to a high wind speed, A=0.8α;

[0091] The air outlet of the air conditioner is adjusted to the medium wind level, A = 0.6α;
