Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following is for reference. Figures 1-11 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0026] Reference Figure 1 and Figure 2According to an embodiment of the present invention, the air conditioner 100 includes an air conditioner body 10. The air conditioner body 10 has a communicating air duct 10a and an air outlet 10b, the air outlet 10b extending along a first direction. Here, "first direction" refers to... Figure 1 The F1 direction in the equation refers to the left and right directions.

[0027] The air conditioner 100 also includes an air guide device 20, and there is at least one air guide device 20. The air guide device 20 is disposed on the air conditioner body 10 and includes a drive assembly 21 and an air guide plate 22. The drive assembly 21 is used to drive the air guide plate 22 to rotate about a rotation axis extending along a first direction. The air guide plate 22 is used to open and close at least part of the air outlet 10b.

[0028] Specifically, when the air conditioner 100 is working, the air guide plate 22 rotates around the rotation axis extending in the first direction under the drive of the drive assembly 21, thereby opening at least part of the air outlet 10b so that the air conditioner 100 can deliver air normally; when the air conditioner 100 is turned off, the drive assembly 21 drives the air guide plate 22 to rotate in the opposite direction around the rotation axis extending in the first direction so that the air guide plate 22 closes the air outlet 10b.

[0029] The air conditioner body 10 includes a duct component 11 and a support member 12, with the duct component 11 defining the duct 10a.

[0030] In some embodiments, the air duct component 11 and the support member 12 are formed separately, the support member 12 is installed on the air duct component 11, and the support member 12 is arranged with the drive assembly 21 in a first direction, and the air guide plate 22 is rotatably connected to the support member 12.

[0031] According to the embodiment of the present invention, the air conditioner 100, by setting the duct component 11 and the support component 12 to be molded separately, can simplify the molding difficulty of the duct component 11 and the support component 12, thereby reducing production costs and improving production efficiency. Furthermore, it facilitates the separate design of the structure of the support component 12, thereby changing the connection method between the support component 12 and the air guide plate 22, simplifying the installation steps of the air guide plate 22, further improving the production efficiency of the air conditioner 100, and also facilitating later maintenance. In addition, the support component 12 and the drive assembly 21 are arranged in the first direction, and the support component 12 can provide auxiliary support for the air guide plate 22, which helps to improve the installation reliability and rotational stability of the air guide plate 22.

[0032] Reference Figure 3 In some embodiments, the support 12 is made of polyoxymethylene material.

[0033] As the air guide plate 22 rotates, the part where it is connected to the support member 12 will rub frequently. After a long period of use, the support member 12 and the air guide plate 22 may experience varying degrees of wear, which will affect the rotational connection between the air guide plate 22 and the support member 12. This may result in problems such as the air guide plate 22 not rotating smoothly or even making abnormal noises.

[0034] Therefore, in the above technical solution, by making the support member 12 out of polyoxymethylene (POM), the excellent self-lubricating properties and low coefficient of friction of POM can provide good lubrication for the support member 12 and the air guide plate 22, making the air guide plate 22 rotate more smoothly, reducing frictional loss at the rotating connection between the air guide plate 22 and the support member 12, and preventing abnormal noise from the air guide plate 22 during rotation. At the same time, POM also has high mechanical strength and rigidity; therefore, the support member 12 made of POM material has high durability.

[0035] Reference Figures 3-5 In some embodiments, the support member 12 is snapped into connection with the air duct component 11.

[0036] By snapping the support member 12 to the air duct component 11, the connection between the support member 12 and the air duct component 11 does not require additional connecting parts. This not only simplifies the connection between the support member 12 and the air duct component 11, but also reduces the number of parts and lowers production costs.

[0037] Reference Figures 3-5 In some examples, the support member 12 is connected to the air duct component 11 via a first snap-fit ​​structure 30 and a second snap-fit ​​structure 40.

[0038] The first snap-fit ​​structure 30 includes a first snap-fit ​​part 31 and a first mating part 32 that are snap-fitted together. One of the first snap-fit ​​part 31 and the first mating part 32 is provided on the support member 12 and the other is provided on the air duct component 11.

[0039] The second snap-fit ​​structure 40 includes a second snap-fit ​​part 41 and a second mating part 42 that are snap-fitted together. One of the second snap-fit ​​part 41 and the second mating part 42 is provided on the support member 12 and the other is provided on the air duct component 11.

[0040] In the above technical solution, by setting the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40, when the support member 12 is connected to the air duct component 11, it can be snapped by the first snap-fit ​​part 31 and the first mating part 32, and by the second snap-fit ​​part 41 and the second mating part 42. This can greatly improve the connection reliability between the support member 12 and the air duct component 11 and reduce the possibility of the support member 12 and the air duct component 11 falling off.

[0041] Reference Figure 3 and Figure 5In some specific examples, the first snap-fit ​​portion 31 is an elastic buckle 311, and the support member 12 is configured to rotate relative to the air duct component 11 in the state of being snapped together with the second snap-fit ​​portion 41 and the second mating portion 42, and to snap together with the first mating portion 32 when the first snap-fit ​​portion 31 undergoes elastic deformation.

[0042] The following explanation uses an example where the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40 are arranged in the second direction, the first snap-fit ​​part 31 and the second snap-fit ​​part 41 are provided on the support member 12, and the first mating part 32 and the second mating part 42 are provided on the air duct component 11. Here, the second direction is the F2 direction in the figure, that is, the front-to-back direction.

[0043] Reference Figures 3-5 The second snap-fit ​​portion 41 is positioned closer to the air outlet 10b on the support member 12 than the first snap-fit ​​portion 31, and the second mating portion 42 is positioned closer to the air outlet 10b on the air duct component 11 than the first mating portion 32. When connecting the support member 12 and the air duct component 11 using the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40, the second snap-fit ​​part 41 is first snapped into the second mating part 42. Then, with the second snap-fit ​​structure 40 as the rotation center, the support member 12 is rotated in a direction close to the first mating part 32, so that the first snap-fit ​​part 31 contacts the first mating part 32. Since the first snap-fit ​​part 31 is an elastic buckle 311, after the first snap-fit ​​part 31 contacts the first mating part 32, the support member 12 is rotated again, and the elastic buckle 311 deforms. Thus, the elastic buckle 311 can snap into the first mating part 32. After the elastic buckle 311 is fully snapped into the first mating part 32, the elastic buckle 311 can recover its elasticity. Thus, the support member 12 and the air duct component 11 are connected through the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40.

[0044] If it is necessary to disassemble the support member 12, the elastic buckle 311 can be lifted up, so that the support member 12 can rotate relative to the air duct component 11 at a certain angle with the second locking structure 40 as the rotation center until the elastic buckle 311 separates from the first mating part 32, and then the second locking part 41 separates from the second mating part 42, thereby separating the support member 12 from the air duct component 11.

[0045] In the embodiment where the first latching part 31 is positioned closer to the air outlet 10b on the support member 12 than the second latching part 41, and the first mating part 32 is positioned closer to the air outlet 10b on the duct component 11 than the second mating part 42, the connection and disassembly process of the support member 12 and the duct component 11 is similar to that in the above embodiment, and will not be repeated here.

[0046] In the above technical solution, by setting the first snap-fit ​​part 31 as an elastic buckle 311, the first snap-fit ​​part 31 and the first mating part 32 can be snapped together or unsnapped without the aid of tools by rotating the support member 12 while the second snap-fit ​​part 41 and the second mating part 42 are snapped together, greatly simplifying the assembly and disassembly steps of the support member 12 and the air duct component 11.

[0047] For example, the number of the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40 can be one or more. In embodiments where the number of the first snap-fit ​​structure 30 and the second snap-fit ​​structure 40 is multiple, the connection reliability between the support member 12 and the air duct component 11 can be further improved.

[0048] Reference Figures 2-5 In some embodiments, the air duct component 11 has a mounting groove 111 on the side facing the air duct 10a, and the support member 12 includes a mounting part 121 and a support body 122. The mounting part 121 is disposed in the mounting groove 111, and the support body 122 is disposed on the side of the mounting part 121 facing the air guide plate 22, and the support body 122 is rotatably connected to the air guide plate 22.

[0049] The first snap-fit ​​part 31 and the second snap-fit ​​part 41 are both located on the side of the mounting part 121 away from the air guide plate 22.

[0050] In the above technical solution, by providing an installation groove 111 on the side of the air duct component 11 facing the air duct 10a, and setting the support member 12 to include an installation part 121 and a support body 122, the installation part 121 can be installed in the installation groove 111. In this way, after the support member 12 is installed on the air duct component 11, the installation part 121 is as flush as possible with the surface of the air duct component 11, reducing the impact of this position on the airflow.

[0051] In some embodiments, the support member 12 and the air duct component 11 are positioned by a positioning component 50, which includes a positioning protrusion 51 and a positioning recess 52. One of the positioning protrusion 51 and the positioning recess 52 is located on the side of the support member 12 facing the air duct component 11, and the other is located on the side of the air duct component 11 facing the support member 12.

[0052] Specifically, refer to Figure 6 The air duct component 11 has a mounting groove 111 on the side facing the air duct 10a. The support component 12 includes a mounting part 121 and a support body 122. The mounting part 121 is located in the mounting groove 111, and the support body 122 is located on the side of the mounting part 121 facing the air guide plate 22. The support body 122 is rotatably connected to the air guide plate 22.

[0053] The positioning recess 52 is provided in the mounting portion 121, and the positioning protrusion 51 is provided in the mounting groove 111. When connecting the support member 12 and the air duct component 11, the mounting portion 121 can be brought close to the mounting groove 111 first, and then the positioning protrusion 51 can be aligned with the positioning recess 52. The support member 12 is then pushed in the direction close to the mounting groove 111, thereby inserting the positioning protrusion 51 and the positioning recess 52. This allows the support member 12 to be positioned and installed on the air duct component 11.

[0054] In an embodiment where the support member 12 and the air duct component 11 are connected via a first snap-fit ​​structure 30, a second snap-fit ​​structure 40, and a positioning component 50, after the second snap-fit ​​portion 41 is snapped into the second mating portion 42, the support member 12 is rotated to a position where the positioning recess 52 and the positioning protrusion 51 are aligned. Then, the support member 12 is rotated in a direction close to the first mating portion 32. After the positioning protrusion 51 and the positioning recess 52 are inserted, the first snap-fit ​​portion 31 is snapped into the first mating portion 32, thereby achieving the connection between the support member 12 and the air duct component 11.

[0055] Reference Figure 4 In some embodiments, the air duct 10a has a first air duct wall 10a1 and a second air duct wall 10a2 disposed opposite to each other, and the air duct 10a is at least partially located between the first air duct wall 10a1 and the second air duct wall 10a2.

[0056] The first air duct wall 10a1 and the second air duct wall 10a2 here can guide the airflow, so that the airflow can flow smoothly along the first air duct wall 10a1 and the second air duct wall 10a2 to the air outlet 10b.

[0057] The first air duct wall 10a1 extends from the volute tongue 112 of the air duct component 11 to one side edge of the air outlet 10b, and the support member 12 is installed on the first air duct wall 10a1 or the second air duct wall 10a2.

[0058] In the above technical solution, by setting the support member 12 in the first air duct wall 10a1 or the second air duct wall 10a2, when the air guide plate 22 is in the closed state, the support member 12 is hidden in the air duct 10a, making the appearance of the air conditioner 100 flat and improving the aesthetics of the air conditioner 100.

[0059] Reference Figure 7 and Figure 8 In some embodiments, one of the support member 12 and the air guide plate 22 has a shaft hole 22a, and the other has a connecting shaft 122a, the axial directions of the shaft hole 22a and the connecting shaft 122a both extending along a first direction.

[0060] The shaft hole 22a has an opening 22aa on its circumference. The connecting shaft 122a is adapted to be inserted into the shaft hole 22a through the opening 22aa in the radial direction of the shaft hole 22a, so that the connecting shaft 122a and the shaft hole 22a are rotatably engaged.

[0061] For example, the air guide plate 22 is provided with a shaft hole 22a, and the support member 12 is provided with a connecting shaft 122a. When connecting the air guide plate 22 and the support member 12, the opening 22aa of the shaft hole 22a can be aligned with the connecting shaft 122a first, and then the air guide plate 22 can be pressed. During this process, the opening 22aa of the shaft hole 22a will undergo elastic deformation, and the connecting shaft 122a can be inserted into the shaft hole 22a through the opening 22aa. After the connecting shaft 122a is inserted into the shaft hole 22a, the connecting shaft 122a will not easily slide out of the opening 22aa of the shaft hole 22a, thereby realizing the rotational engagement between the connecting shaft 122a and the shaft hole 22a, and thus realizing the connection between the air guide plate 22 and the support member 12.

[0062] For example, the support member 12 has a shaft hole 22a and the air guide plate 22 has a connecting shaft 122a. When connecting the air guide plate 22 and the support member 12, the connecting shaft 122a of the air guide plate 22 can be aligned with the opening 22aa of the shaft hole 22a. Then, the air guide plate 22 is pressed so that the connecting shaft 122a is inserted into the shaft hole 22a from the opening 22aa. This allows for the rotational engagement of the connecting shaft 122a with the shaft hole 22a, thereby connecting the air guide plate 22 and the support member 12.

[0063] In the first direction, one axial end of the connecting shaft 122a is provided with an anti-detachment protrusion 122a1. After the connecting shaft 122a is rotatably engaged with the shaft hole 22a, the anti-detachment protrusion 122a1 can limit the connecting shaft 122a in the first direction, thereby preventing the connecting shaft 122a from disengaging from the shaft hole 22a in the first direction during the rotation of the air guide plate 22, thereby improving the reliability of the connection between the air guide plate 22 and the support member 12.

[0064] In the above technical solution, by setting a shaft hole 22a in one of the support member 12 and the air guide plate 22, and setting a connecting shaft 122a in the other, and setting an opening 22aa on the periphery of the shaft hole 22a, the connecting shaft 122a can be inserted into the shaft hole 22a from the opening 22aa along the radial direction of the shaft hole 22a, thereby realizing the rotational engagement between the connecting shaft 122a and the shaft hole 22a. Compared with the connection method using a pin in related technologies, on the one hand, the pin is eliminated, reducing the number of parts and thus reducing production costs; on the other hand, no special tools are required for installation, which simplifies the installation steps of the air guide plate 22, improves the production efficiency of the air conditioner 100, and facilitates later maintenance.

[0065] In addition, this connection method makes the structure of the side of the air guide plate 22 facing the support member 12 simpler and does not affect the rotation of the air guide plate 22, so that the air guide plate 22 can rotate normally when the air conditioner 100 is running.

[0066] Reference Figure 7 In some specific embodiments, the opening 22aa has a first edge 22aa1 and a second edge 22aa2 disposed opposite to each other in the circumferential direction of the shaft hole 22a, the distance between the first edge 22aa1 and the second edge 22aa2 is D1, and the diameter of the connecting shaft 122a is D2, where 0.1mm ≤ D2 - D1 ≤ 10mm. For example, the difference between D2 and D1 can be 0.1mm, 1mm, 3mm, 5mm, 7mm, 9mm, 10mm, etc.

[0067] With this configuration, after the connecting shaft 122a and the shaft hole 22a are assembled in place, the first edge 22aa1 and the second edge 22aa2 can be used to limit the connecting shaft 122a, preventing the connecting shaft 122a from disengaging from the shaft hole 22a during the rotation of the air guide plate 22, thus preventing the air guide plate 22 from disengaging from the support member 12. This effectively improves the connection reliability between the air guide plate 22 and the support member 12.

[0068] Reference Figure 7 In some embodiments, the opening 22aa has a first edge 22aa1 and a second edge 22aa2 disposed opposite to each other in the circumferential direction of the shaft hole 22a. In a plane perpendicular to the first direction, the projections of the first edge 22aa1 and the second edge 22aa2 on the plane form an angle α with the line connecting the center of the shaft hole 22a, where α < 180°.

[0069] In the above technical solution, by setting the angle α between the projections of the first edge 22aa1 and the second edge 22aa2 on the plane and the line connecting them to the center of the shaft hole 22a to be less than 180°, the distance between the first edge 22aa1 and the second edge 22aa2 is less than the diameter of the connecting shaft 122a. After the connecting shaft 122a and the shaft hole 22a are assembled in place, the first edge 22aa1 and the second edge 22aa2 of the shaft hole 22a stop the connecting shaft 122a, preventing the connecting shaft 122a from disengaging from the opening 22aa and the shaft hole 22a during the rotation of the air guide plate 22, thus preventing the air guide plate 22 from disengaging from the support member 12. This effectively improves the connection reliability between the air guide plate 22 and the support member 12.

[0070] Reference Figure 8 and Figure 9 In some embodiments, the hole wall of the shaft hole 22a and / or the peripheral wall of the connecting shaft 122a have an oil storage groove 22ab.

[0071] Specifically, since the shaft hole 22a and the connecting shaft 122a are in rotational engagement, the connecting shaft 122a will frequently rub against the peripheral wall of the shaft hole 22a during the rotation of the air guide plate 22. As the usage time increases, the hole wall of the shaft hole 22a and the peripheral wall of the connecting shaft 122a will wear to varying degrees, which will often affect the rotation of the air guide plate 22, and may even cause the air guide plate 22 to be difficult to rotate or make abnormal noises.

[0072] By providing an oil storage groove 22ab in the hole wall of the shaft hole 22a and / or the peripheral wall of the connecting shaft 122a, a lubricating medium, such as lubricating oil, can be placed in the oil storage groove 22ab. This forms a lubricating layer between the hole wall of the shaft hole 22a and the peripheral wall of the connecting shaft 122a. During the rotation of the air guide plate 22, the wear between the hole wall of the shaft hole 22a and the peripheral wall of the connecting shaft 122a can be effectively reduced. This not only makes the rotation of the air guide plate 22 smoother, but also prevents abnormal noise caused by rotational friction between the hole wall of the shaft hole 22a and the peripheral wall of the connecting shaft 122a.

[0073] For example, the oil storage groove 22ab can be provided on the hole wall of the shaft hole 22a, or it can be provided on the peripheral wall of the connecting shaft 122a. Of course, the oil storage groove 22ab can also be provided on both the hole wall of the shaft hole 22a and the peripheral wall of the connecting shaft 122a.

[0074] Reference Figure 2 In some examples, there are multiple air guiding devices 20, and each air guiding device 20 includes at least a first air guiding device 23 and a second air guiding device 24. The first air guiding device 23 includes a first air guiding plate 231, and the second air guiding device 24 includes a second air guiding plate 241. The first air guiding plate 231 and the second air guiding plate 241 are respectively used to open and close different parts of the air outlet 10b. Both the first air guiding plate 231 and the second air guiding plate 241 are rotatably connected to the support member 12.

[0075] For example, the air conditioner 100 can be a wall-mounted air conditioner. The air outlet 10b is located at the lower front part of the air conditioner body 10. Specifically, the first part of the air outlet 10b is located at the lower front side of the air conditioner body 10, and the second part of the air outlet 10b is located at the bottom front side of the air conditioner body 10. The first air guide plate 231 can be used to open and close the first part of the air outlet 10b, and the second air guide plate 241 can be used to open and close the second part of the air outlet 10b.

[0076] In the above technical solution, by setting the air guide device 20 to include at least a first air guide device 23 and a second air guide device 24, a portion of the air outlet 10b can be opened and closed using the first air guide plate 231 of the first air guide device 23, and the other portion of the air outlet 10b can be opened and closed using the second air guide plate 241 of the second air guide device 24.

[0077] Furthermore, by rotatably connecting both the first air guide plate 231 and the second air guide plate 241 to the support member 12, on the one hand, the support member 12 can provide auxiliary support for the first air guide plate 231 and the second air guide plate 241 respectively, thereby improving the installation reliability and rotational stability of the first air guide plate 231 and the second air guide plate 241; on the other hand, by sharing a support member 12, the number of parts can be reduced, production costs can be lowered, and too many parts can be avoided from obstructing the airflow.

[0078] Continue to refer to Figure 2 In some specific examples, there is one first air guide plate 231. In the first direction, the first air guide plate 231 extends from one end of the air outlet 10b to the other end of the air outlet 10b, and the support member 12 is rotatably connected to the middle of the first air guide plate 231 in the first direction. That is to say, in this example, the first air guide plate 231 is a plate that spans both ends of the air outlet 10b.

[0079] Here, "the first air guide plate 231 in the middle of the first direction" can refer to the exact center of the first air guide plate 231 in the first direction, or it can refer to the position of the first air guide plate 231 near the exact center in the first direction.

[0080] In the above example, by rotating the support member 12 to the first air guide plate 231 at the middle of the first direction, the installation reliability and rotational stability of the first air guide plate 231 can be improved, the structural strength of the first air guide plate 231 can be improved, and the probability of deformation of the first air guide plate 231 can be reduced, thereby ensuring the air guiding effect of the first air guide plate 231.

[0081] In other specific examples, there are multiple first air guide plates 231, which are arranged in a first direction, and two adjacent first air guide plates 231 are rotatably connected to the same support member 12.

[0082] In the above example, by setting multiple first air guide plates 231 and arranging multiple first air guide plates 231 in the first direction, the opening and closing of the air outlet 10b at different positions can be realized in the first direction, thereby realizing different air supply ranges. This increases the sense of air supply layering of the air conditioner 100 and is conducive to improving the user experience.

[0083] Furthermore, by rotatably connecting two adjacent first air guide plates 231 to the same support member 12, that is, by having two adjacent first air guide plates 231 share the same support member 12, the installation reliability and rotational stability of the first air guide plates 231 can be improved, the number of parts can be reduced, the production cost can be reduced, and too many parts can be avoided from obstructing the airflow.

[0084] And / or, in some specific examples, there is one second air guide plate 241, which extends from one end of the air outlet 10b to the other end of the air outlet 10b in the first direction, and the support member 12 is rotatably connected to the middle of the second air guide plate 241 in the first direction.

[0085] Here, "the middle of the second air guide plate 241 in the first direction" can refer to the exact center of the second air guide plate 241 in the first direction, or it can refer to the position of the second air guide plate 241 near the exact center in the first direction.

[0086] In the above example, by rotating the support member 12 to the middle of the second air guide plate 241 in the first direction, the installation reliability and rotational stability of the second air guide plate 241 can be improved, the structural strength of the second air guide plate 241 can be improved, and the probability of deformation of the second air guide plate 241 can be reduced, thereby ensuring the air guiding effect of the second air guide plate 241.

[0087] And / or, in some other specific examples, there are multiple second air guides 241, which are arranged in a first direction, and two adjacent second air guides 241 are rotatably connected to the same support member 12.

[0088] In the above technical solution, by setting multiple second air guide plates 241 and arranging multiple second air guide plates 241 in the first direction, the opening and closing of the air outlet 10b at different positions can be realized in the first direction, thereby realizing different air supply ranges. This increases the sense of air supply layering of the air conditioner 100 and is conducive to improving the user experience.

[0089] Furthermore, by rotatably connecting two adjacent second air guide plates 241 to the same support member 12, that is, by having two adjacent second air guide plates 241 share the same support member 12, the installation reliability and rotational stability of the second air guide plates 241 can be improved, the number of parts can be reduced, the production cost can be reduced, and too many parts can be avoided from obstructing the airflow.

[0090] Reference Figure 2 In some embodiments, the first direction is the left-right direction, the length of the air conditioner body 10 extends in the left-right direction and the height extends in the up-down direction, that is, the air conditioner 100 is a wall-mounted air conditioner.

[0091] The air outlet 10b includes a first air outlet 10b1 and a second air outlet 10b2 connected together. The first air outlet 10b1 is located at the lower front side of the air conditioner body 10, and the second air outlet 10b2 is located at the bottom front side of the air conditioner body 10. The first air guide plate 231 is used to open and close the first air outlet 10b1, and the second air guide plate 241 is used to open and close the second air outlet 10b2.

[0092] The rotation axis of the first air guide plate 231 and the rotation axis of the second air guide plate 241 are arranged at intervals, and the rotation axis of the first air guide plate 231 is located above the rotation axis of the second air guide plate 241.

[0093] In the above technical solution, by setting the air outlet 10b to include a first air outlet 10b1 and a second air outlet 10b2 that are connected, and setting the first air outlet 10b1 at the lower front side of the air conditioner body 10 and the second air outlet 10b2 at the bottom front side of the air conditioner body 10, the air volume of the air conditioner 100 can be increased. By setting the first air guide plate 231 to open and close the first air guide plate and the second air guide plate 241 to open and close the second air outlet 10b2, the opening and closing angles of the first air guide plate 231 and the second air guide plate 241 can be controlled according to the cooling and heating modes of the air conditioner 100. Thus, when the air conditioner 100 is in cooling mode, most of the cold air is guided out of the first air outlet 10b1, and when the air conditioner 100 is in heating mode, most of the cold air is guided out of the second air outlet 10b2, thereby improving the cooling and heating effect of the air conditioner 100.

[0094] Reference Figure 2 , Figure 3 and Figure 10 In some specific embodiments, the support member 12 includes a first support portion 122b, and the first air guide plate 231 has a first connecting lug 2311 on the side facing the support member 12, and the first connecting lug 2311 is rotatably connected to the first support portion 122b.

[0095] The first air guide plate 231 is rotatable between the first open position of opening the first air outlet 10b1 and the first closed position of closing the first air outlet 10b1. The first support part 122b has a first limiting part 122b1. When the first air guide plate 231 is in the first open position, the first limiting part 122b1 stops the first connecting lug 2311.

[0096] It should be noted that the "first closed position" refers to the position when the first air guide plate 231 completely closes the first air outlet 10b1. The first air guide plate 231 is set to be in the first closed position when the air conditioner 100 is in the off state. The "first open position" refers to the extreme position of the first air guide plate 231 when it rotates outward.

[0097] For example, when the air conditioner 100 is started, the lower end of the first air guide plate 231 rotates outward from the first closed position to the first open position, opening the first air outlet 10b1 so that cold or hot air in the air duct 10a can be blown out from the first air outlet 10b1. When the first air guide plate 231 rotates to the first open position, the first limiting part 122b1 contacts the first connecting lug 2311 and stops the first connecting lug 2311, so that the lower end of the first air guide plate 231 cannot continue to rotate outward, thus avoiding the first air guide plate 231 from colliding with the first air duct wall 10a1 and causing damage to the first air guide plate 231.

[0098] In the above technical solution, by configuring the support member 12 to include a first support portion 122b and configuring the first air guide plate 231 to have a first connecting lug 2311 on the side facing the support member 12, the first air guide plate 231 can be rotated between a first closed position and a first open position by utilizing the rotatable connection between the first connecting lug 2311 and the first support portion 122b, thereby realizing the opening and closing of the first air outlet 10b1; by configuring the first support portion 122bb to include a first limiting portion 122b1, when the first air guide plate 231 rotates to the first open position, the first limiting portion 122b1 can stop the first connecting lug 2311, thereby limiting the first air guide plate 231 and preventing the first air guide plate 231 from continuing to rotate to the first air duct wall 10a1 and colliding with the first air duct wall 10a1, causing damage to the first air guide plate 231 and affecting the air supply of the air conditioner 100.

[0099] Reference Figure 2 and 3 and further refer to Figure 10 and Figure 11 In some examples, the support member 12 includes a second support portion 122c, and the second air guide plate 241 has a second connecting lug 2411 on the side facing the support member 12, and the second connecting lug 2411 is rotatably connected to the second support portion 122c.

[0100] The second air guide plate 241 is adapted to rotate along the first rotation direction from the second closed position of closing the second air outlet 10b2 to the second open position of opening the second air outlet 10b2. The second support part 122c has a second limiting part 122c1. When the second air guide plate 241 is in the second open position, the second limiting part 122c1 stops the second connecting lug 2411. The second air guide plate 241 is adapted to rotate in the second rotation direction from the second closed position of closing the second air outlet 10b2 to the third open position of opening the second air outlet 10b2. The second rotation direction is opposite to the first rotation direction. The second support part 122c has a third limiting part 122c2. When the second air guide plate 241 is in the third open position, the third limiting part 122c2 stops the second connecting lug 2411.

[0101] It should be noted that the "second closed position" refers to the position when the second air guide plate 241 completely closes the second air outlet 10b2. The second air guide plate 241 is set to be in the second closed position when the air conditioner 100 is in the off state. The "second open position" refers to the extreme position of the second air guide plate 241 when it rotates outward. The "third open position" refers to the extreme position of the second air guide plate 241 when it rotates inward.

[0102] The "first direction of rotation" can be either outward or inward. If the "first direction of rotation" is outward, then the "second direction of rotation" is inward; if the "first direction of rotation" is inward, then the "second direction of rotation" is outward.

[0103] The following explanation will take the example of the first direction of rotation being outward rotation.

[0104] For example, when the air conditioner 100 is started, the second air guide plate 241 can rotate in the first rotation direction, that is, the lower end of the second air guide plate 241 rotates outward and from the second closed position to the second open position, thereby opening the second air outlet 10b2. When the second air guide plate 241 rotates to the second open position, the second limiting part 122c1 contacts the second connecting lug 2411 and stops the second connecting lug 2411, so that the lower end of the second air guide plate 241 cannot continue to rotate outward. At this time, the second air guide plate 241 is at least partially located inside the air duct 10a, and the second air guide plate 241 can block most of the cold or hot air flowing to the first air outlet 10b1 and guide it to the second air outlet 10b2.

[0105] For example, when the air conditioner 100 is started, the second air guide plate 241 can rotate in the second rotation direction, that is, the lower end of the second air guide plate 241 rotates inward and rotates from the second closed position to the third open position, thereby opening the second air outlet 10b2. When the second air guide plate 241 rotates to the third open position, the second limiting part 122c1 contacts the second connecting lug 2411 and stops the second connecting lug 2411, so that the lower end of the second air guide plate 241 cannot continue to rotate inward. At this time, most of the second air guide plate 241 is located outside the second air outlet 10b2, which can extend the guiding distance of the second air guide plate 241, so that the cold air and hot air flowing out of the second air outlet 10b2 can flow to the lower part of the air conditioner 100 better.

[0106] In the above technical solution, by configuring the support member 12 to include a second support portion 122c and configuring the second air guide plate 241 to have a second connecting lug 2411 on the side facing the support member 12, the first air guide plate 231 can be rotated between a second closed position and a second open position, or moved between a second closed position and a third open position, thereby realizing the opening and closing of the second air outlet 10b2. By configuring the second support portion 122c to include a second limiting portion 122c1, when the second air guide plate 241 rotates to the second open position or to the third open position, the second limiting portion 122c1 stops the second connecting lug 2411, thereby limiting the second air guide plate 241 and preventing the second air guide plate 241 from continuing to rotate in the first rotation direction or in the second rotation direction, and thus colliding with the support member 12, causing damage to the second air guide plate 241 and affecting the air supply of the air conditioner 100.

[0107] For example, in an embodiment where the first rotation direction is inward rotation, the motion state of the second air guide plate 241 is similar to that in the above embodiment, and will not be repeated here.
