[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] Traditional up / down air supply type air conditioners generally have relatively concentrated air intake when in use, resulting in poor air intake sound quality, and the noise generated by the air conditioners is relatively high, which can easily cause discomfort to users and reduce the user experience. Based on this, the present application proposes an air supply structure 10 of an air conditioner and an air conditioner. When in use, the air supply structure 10 of the air conditioner and the air conditioner can adjust the blowing direction of the air according to the operating mode of the air conditioner and have low noise when in use, thereby improving the user experience.

[0038] Please refer to Figure 1 and Figure 2 The air conditioner in one embodiment includes an air supply structure 10, an air inlet panel 20, an evaporator 30 and an air outlet panel 40 of the air conditioner. The air flow enters along the air inlet panel 20, passes through the evaporator 30 and enters the air supply structure 10 of the air conditioner after heat exchange with the evaporator 30, and is discharged along the air outlet panel 40 under the action of the air supply structure 10 of the air conditioner.

[0039] Please refer to Figure 1 and Figure 2The air supply structure 10 of the air conditioner in one embodiment includes an air supply duct 100 and a crossflow blade 200. The air supply duct 100 is formed with an air inlet 110, a first air outlet 120 and a second air outlet 130. The air outlet direction of the first air outlet 120 is different from the air outlet direction of the second air outlet 130. The crossflow blade 200 is arranged in the air supply duct 100 or the air inlet 110 is provided. The crossflow blade 200 is used to introduce air along the air inlet 110 and blow it out along the first air outlet 120 and / or the second air outlet 130. At this time, the air supply structure 10 of the air conditioner has less noise when in use, thereby improving the user experience; further, when the crossflow blade 200 is used to introduce airflow, the heat exchange of the evaporator 30 can be made more uniform, the evaporator 30 can be efficiently utilized, and the heat exchange efficiency is increased.

[0040] It should be noted that the different air outlet directions of the first air outlet 120 and the second air outlet 130 refer to: 1. The first air outlet 120 and the second air outlet 130 are located at different heights. In this case, it can be considered that the air outlet directions of the first air outlet 120 and the second air outlet 130 are different. For example, please refer to Figure 2 , the first air outlet 120 and the second air outlet 130 are spaced apart along the height direction of the air supply duct 100. Although the overall direction trends of the first air outlet 120 and the second air outlet 130 are consistent, the air outlet heights of the first air outlet 120 and the second air outlet 130 are different. At this time, the effects on the human body are different. It is considered that the air outlet directions of the first air outlet 120 and the second air outlet 130 are different; 2. The directions of the first air outlet 120 and the second air outlet 130 are different. At this time, it is also considered that the air outlet directions of the first air outlet 120 and the second air outlet 130 are different.

[0041] Please refer to Figure 1 The air supply structure 10 of the air conditioner also includes a wind shielding mechanism 300 , which includes a first wind shielding member 310 and a second wind shielding member 320 . The first wind shielding member 310 is used to open or close the first air outlet 120 , and the second wind shielding member 320 is used to open or close the second air outlet 130 .

[0042] For details, please refer to Figure 4 The wind shielding mechanism 300 is disposed in the air supply duct 100 , so that the wind shielding mechanism 300 can be integrated into the air supply duct 100 , thereby reducing the overall size of the air supply structure 10 of the entire air conditioner.

[0043] The first wind shield 310 and the second wind shield 320 are configured to selectively open the first air outlet 120 or the second air outlet 130 or both of them according to the air supply demand. Figure 2The first air outlet 120 and the second air outlet 130 are arranged at intervals along the height direction of the air supply duct 100. Figure 2 As shown in L. Taking the first air outlet 120 as the upper air outlet and the second air outlet 130 as the lower air outlet as an example, the principle of the air supply structure 10 of the air conditioner switching the air outlet direction according to user needs is explained.

[0044] For example, see Figure 4 When the user's air supply demand is upward air outlet, the first air shield 310 opens the first air outlet 120, and the second air shield 320 closes the second air outlet 130. At this time, the air conditioner can be in cooling mode, and when the wind is discharged along the first air outlet 120, the cold wind can be prevented from blowing directly to the user.

[0045] For example, see Figure 5 When the user's air supply demand is downward air outlet, the first air shield 310 closes the first air outlet 120, and the second air shield 320 opens the second air outlet 130. At this time, the air conditioner can be in heating mode, and when the air is discharged along the second air outlet 130, when the hot air blows towards the user, the user's experience can be improved.

[0046] For example, see Figure 6 When the user's air supply requirement is to blow air up / down at the same time, the first wind shield 310 opens the first air outlet 120 and the second wind shield 320 opens the second air outlet 130 at the same time.

[0047] It is understandable that in the aforementioned embodiment, the first air outlet 120 and the second air outlet 130 can be directly switched to discharge air according to the needs of the user without limiting the operating mode of the air conditioner. For example, when the air conditioner is in cooling mode, the user can control the first wind shield 310 to open the first air outlet 120 and the second wind shield 320 to close the second air outlet 130 as needed. Of course, the first wind shield 310 can also be controlled to close the first air outlet 120 and the second wind shield 320 to open the second air outlet 130 as needed. Other modes are similar and are not listed here one by one.

[0048] Please refer to Figure 1 and Figure 5 In some embodiments, the wind shield mechanism 300 also includes a first drive component 330 and a second drive component 340. The first drive component 330 is used to drive the first wind shield member 310 to move or rotate to open or close the first air outlet 120; the second drive component 340 is used to drive the second wind shield member 320 to move or rotate to open or close the second air outlet 130.

[0049] Specifically, the air conditioner may include a control module, which controls the operation of the first drive component 330 and / or the second drive component 340 according to received user needs, and further controls the opening of the first air outlet 120 and / or the opening of the second air outlet 130 accordingly.

[0050] The implementation of the windshield first drive assembly 330 and the second drive assembly 340 is described by taking the first windshield member 310 rotating to open or close the first air outlet 120 and the second windshield member 320 rotating to open or close the second air outlet 130 as an example.

[0051] For example, see Figure 5 In some embodiments, the first driving assembly 330 includes a first driving member 332 and a first rotating member 334, the first rotating member 334 is connected to the first wind shielding member 310, and the first driving member 332 is used to drive the first rotating member 334 to rotate and drive the first wind shielding member 310 to rotate to open or close the first air outlet 120. The first driving member 332 can be fixed in the air supply duct 100, the first driving member 332 can be a motor, the first wind shielding member 310 can be a wind shield, and the first rotating member 334 can be a shaft or other rotating elements.

[0052] Please refer to Figure 5 The second driving assembly 340 includes a second driving member 342 and a second rotating member 344. The second rotating member 344 is connected to the second wind shielding member 320. The second driving member 342 is used to drive the second rotating member 344 to rotate and drive the second wind shielding member 320 to rotate to open or close the second air outlet 130. The second driving member 342 can be fixed in the air supply duct 100, the second driving member 342 can be a motor, the second wind shielding member 320 can be a windshield, and the second rotating member 344 can be a shaft or other rotating elements.

[0053] In some embodiments, the first rotating member 334 includes a first active toothed body (not shown) and a first driven toothed body (not shown) meshing with the first active toothed body, the first wind shield 310 is connected to the first driven toothed body, and the first driving member 332 is connected to the first active toothed body for driving the first active toothed body to rotate and drive the first driven toothed body to rotate.

[0054] The first active toothed body can be a single gear or a gear set with two or more gears meshing together. The first driven toothed body can be a single gear or a gear set with two or more gears meshing together. The first active toothed body can also be composed of a single gear and a rack meshing together with the gear.

[0055] Please refer to Figure 5In some embodiments, the first active toothed body is a first active gear 3342, the first driven geared body includes a first driven gear 3344 meshing with the first active gear 3342 and a first arc-shaped rack 3346 meshing with the first driven gear 3344, and the first wind shield 310 is connected to the first arc-shaped rack 3346. The first active gear 3342 rotates under the drive of the first driving member 332, and drives the first driven gear 3344 to rotate. Since the first arc-shaped rack 3346 itself is an arc-shaped structure, the first driven gear 3344 drives the first arc-shaped rack 3346 to move along the arc direction accordingly while rotating. In other words, the first arc-shaped rack 3346 will drive the first wind shield 310 to rotate, thereby realizing the opening or closing of the first air outlet 120.

[0056] Please refer to Figure 5 In some embodiments, the first wind shield 310 is an arc-shaped wind shield, and the concave side of the arc-shaped wind shield faces the side of the cross-flow fan blade 200 where the air is discharged. The setting of the arc-shaped wind shield will convert the air flow pressure into static pressure. A larger static pressure can ensure a longer air supply distance. The concave side of the arc-shaped wind shield faces the side of the cross-flow fan blade 200 where the air is discharged, which can ensure that the static pressure distribution inside the air supply duct 100 is more uniform.

[0057] In some embodiments, the second rotating member 344 includes a second active toothed body (not shown) and a second driven toothed body meshing with the second active toothed body (not shown), the second wind shield 320 is connected to the second driven toothed body, and the second driving member 342 is connected to the second active toothed body for driving the second active toothed body to rotate and drive the second driven toothed body to rotate.

[0058] The second active toothed body can be a single gear or a gear set with two or more gears meshing together. The second driven toothed body can be a single gear or a gear set with two or more gears meshing together. The second active toothed body can also be composed of a single gear and a rack meshing together with the gear.

[0059] Please refer to Figure 5In some embodiments, the second active toothed body is a second active gear 3442, the second driven geared body includes a second driven gear 3444 meshing with the second active gear 3442 and a second arc-shaped rack 3446 meshing with the second driven gear 3444, and the second wind shield 320 is connected to the second arc-shaped rack 3446. The second active gear 3442 rotates under the drive of the second driving member 342, and drives the second driven gear 3444 to rotate. Since the second arc-shaped rack 3446 itself is an arc-shaped structure, the second driven gear 3444 drives the second arc-shaped rack 3446 to move along the arc direction when rotating. In other words, the second arc-shaped rack 3446 drives the second wind shield 320 to rotate, thereby realizing opening or closing the second air outlet 130.

[0060] Please refer to Figure 5 In some embodiments, the second wind shield 320 is an arc-shaped wind shield, and the concave side of the arc-shaped wind shield faces the side of the cross-flow fan blade 200 where the air is discharged. The setting of the arc-shaped wind shield will convert the airflow dynamic pressure into static pressure. A larger static pressure can ensure a longer air supply distance. The concave side of the arc-shaped wind shield faces the side of the cross-flow fan blade 200 where the air is discharged, which can ensure that the static pressure distribution inside the air supply duct 100 is more uniform.

[0061] Please refer to Figure 7 In other embodiments, the first wind shield 310 and the second wind shield 320 can also be configured as square shields, such as rectangular or square shields. It is understandable that the shapes of the first wind shield 310 and the second wind shield 320 can be configured as needed.

[0062] Please refer to Figure 6 and Figure 7 In some embodiments, one end of the first wind shield 310 can be disposed in the middle of the air supply duct 100, and the other end can close the first air outlet 120 by contacting the edge of the first air outlet 120. Figure 8 In other embodiments, one end of the first wind shield 310 can be directly and rotatably connected to the edge of the first air outlet 120, the area of ​​the first wind shield 310 is greater than or equal to the area of ​​the first air outlet 120, and the first air outlet 120 is opened or closed by rotating the first wind shield 310.

[0063] Please refer to Figure 6 and Figure 7 In some embodiments, one end of the second wind shield 320 can be disposed in the middle of the air supply duct 100, and the other end can close the second air outlet 130 by contacting the edge of the second air outlet 130. Figure 8In other embodiments, one end of the second wind shield 320 can be directly and rotatably connected to the edge of the second air outlet 130, the area of ​​the second wind shield 320 is greater than or equal to the area of ​​the second air outlet 130, and the second air outlet 130 is opened or closed by rotating the second wind shield 320.
