The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “thickness”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “circumferential”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figure 1 As shown, an air conditioner 100 according to an embodiment of the present invention includes a housing 1 and an air outlet device 2 .

[0044] Specifically, if Figure 1As shown, the housing 1 has an air outlet 101, and the housing 1 also has an air inlet 102. An air duct is defined in the housing 1, and the two ends of the air duct are respectively connected with the air inlet 102 and the air outlet 101. A wind wheel 4 is arranged in the air duct, and the wind wheel 4 is rotatably arranged in the air duct. A heat exchanger 5 is also arranged in the housing 1, and the heat exchanger 5 is opposite to the air inlet 102. Under the action of the wind wheel 4, the airflow enters from the air inlet 102, and the airflow entering the housing 1 exchanges heat with the heat exchanger 5. The airflow after the heat exchange is completed is discharged from the air outlet 101 into the room, thereby realizing indoor cooling or heating.

[0045] exist Figure 1 In the example shown, the housing 1 is formed into a columnar shape, the air inlet 102 and the air outlet 101 are both arranged on the outer peripheral wall of the housing 1, and the air inlet 102 and the air outlet 101 are arranged opposite to each other, and the air inlet 102 and the air outlet 101 are both extended in the up-down direction, and the wind wheel 4 is extended in the up-down direction (such as Fig.12 The upper and lower directions shown extend.

[0046] like Figure 6-Figure 8 As shown, the air outlet device 2 includes a fixed air outlet frame 21, a movable air outlet frame 25 and a driving mechanism 29. The fixed air outlet frame 21 is rotatably arranged at the air outlet 101. The fixed air outlet frame 21 has a first air duct 23. The movable air outlet frame 25 is movably arranged on the fixed air outlet frame 21. The movable air outlet frame 25 has a second air duct 27. The second air duct 27 is connected to the first air duct 23. The movable air outlet frame 25 moves between a first position and a second position relative to the fixed air outlet frame 21. In the first position, as shown in FIG. Figure 7 As shown, the total length of the first air duct 23 and the second air duct 27 along the air flow direction is L1. In the second position, as shown in FIG. Figure 8 As shown, the total length of the first air duct 23 and the second air duct 27 along the air flow direction is L2, and satisfies: L2>L1. The total length of the first air duct 23 and the second air duct 27 only includes the length of an overlapping area of ​​the first air duct 23 and the second air duct 27, that is, the distance between the end of the first air duct 23 and the second air duct 27 located at the most upstream and the end of the first air duct 23 and the second air duct 27 located at the most downstream.

[0047] Therefore, when the air conditioner 100 is in use, the movable air outlet frame 25 can be moved to the second position, so that the total length of the first air duct 23 and the second air duct 27 in the direction of air flow is lengthened, thereby extending the length of the entire air outlet duct, increasing the air supply distance, and when the fixed air outlet frame 21 swings, the air supply range can be increased.

[0048] like Figure 6 As shown, the driving mechanism 29 is disposed on the fixed air outlet frame 21 , and the driving mechanism 29 is connected to the movable air outlet frame 25 to drive the movable air outlet frame 25 to move, thereby facilitating the movement of the movable air outlet frame 25 .

[0049] According to the air conditioner 100 of the embodiment of the present invention, the air outlet device 2 is arranged at the air outlet 101, and the air outlet device 2 includes a fixed air outlet frame 21 and a movable air outlet frame 25, the movable air outlet frame 25 is movably arranged on the fixed air outlet frame 21 and moves between a first position and a second position relative to the fixed air outlet frame 21, and the total length of the first air duct 23 and the second air duct 27 along the air flow direction of the movable air outlet frame 25 when the movable air outlet frame 25 is in the second position is greater than the total length of the first air duct 23 and the second air duct 27 along the air flow direction of the movable air outlet frame 25 when the movable air outlet frame 25 is in the first position. Therefore, when the air conditioner 100 is used, the movable air outlet frame 25 can be located at the second position, so that the length of the entire air outlet duct can be extended, the air supply distance can be increased, and when the fixed air outlet frame 21 swings, the air supply range can be increased.

[0050] In some embodiments of the present invention, the movable air outlet frame 25 is movably disposed in the first air duct 23, and it can be understood that the fixed air outlet frame 21 is sleeved outside the movable air outlet frame 25. In the second position, along the air flow direction, at least part of the movable air outlet frame 25 is located downstream of the fixed air outlet frame 21. In this way, the length of the entire air outlet duct can be extended and the air supply distance can be increased.

[0051] Optionally, in the first position, the movable air outlet frame 25 may be entirely located in the first air duct 23 , or may be partially located in the first air duct 23 .

[0052] Furthermore, a sealing device is provided between the outer wall surface of the movable air outlet frame 25 and the inner wall surface of the first air duct 23 to prevent air from leaking from between the inner wall surface of the first air duct 23 and the outer wall surface of the movable air outlet frame 25 .

[0053] In some embodiments of the present invention, Figure 6-Figure 8 As shown, along the airflow direction, the fixed air outlet frame 21 has a first end 231 and a second end 232, the second end 232 is located downstream of the first end 231, and the mobile air outlet frame 25 is located downstream of the fixed air outlet frame 21, and the mobile air outlet frame 25 is movably connected to the second end 232. It can be understood that the fixed air outlet frame 21 and the mobile air outlet frame 25 are arranged in sequence along the airflow direction. In this way, the first air duct 23 and the second air duct 27 can be better connected, and the step condition at the connection between the first air duct 23 and the second air duct 27 can be improved, and the noise during the airflow process can be reduced.

[0054] Further, in the first position, such as Figure 7 As shown, one end of the inner wall surface of the first air duct 23 close to the second air duct 27 is flush with one end of the inner wall surface of the second air duct 27 close to the first air duct 23, and the inner wall surface of the first air duct 23 and the inner wall surface of the second air duct 27 are smoothly connected, which can reduce the noise during the airflow process.

[0055] like Figure 6-Figure 8 As shown, the air outlet device 2 also includes a wind shield assembly 28, which includes a limit wind shield plate 281 and a limit slot 282. The limit wind shield plates 281 are two and are respectively arranged in the width direction of one of the movable air outlet frame 25 and the fixed air outlet frame 21 (such as Figure 6 The two ends of the limit slots 282 are respectively arranged in the width direction of the other one of the movable air outlet frame 25 and the fixed air outlet frame 21 (as shown in the left and right directions). Figure 6 At both ends of the fixed air outlet frame 21 (in the left and right directions shown in the figure), the two limiting grooves 282 correspond to the two limiting wind shields 281 one by one, and the limiting wind shields 281 are movably arranged in the corresponding limiting grooves 282. The limiting wind shields 281 move in the limiting grooves 282 to play a guiding and limiting role, which facilitates the movement of the mobile air outlet frame 25 relative to the fixed air outlet frame 21. In addition, when the mobile air outlet frame 25 is in the second position, the limiting wind shields 281 play a wind shielding role, preventing wind from leaking out from the gap between the fixed air outlet frame 21 and the mobile air outlet frame 25, thereby ensuring the air output.

[0056] For example, in Figure 6-Figure 8 In the example shown, there are two limit wind shielding plates 281, which are respectively arranged in the width direction of the movable air outlet frame 25 (such as Figure 6 The limit wind shield plate 281 is located at one end of the movable air outlet frame 25 close to the fixed air outlet frame 21, and the width direction of the fixed air outlet frame 21 (as shown in the left and right directions) is Figure 6 Limiting grooves 282 are provided at both ends (left and right directions as shown), the limiting groove 282 is located at one end of the fixed air outlet frame 21 close to the movable air outlet frame 25, the opening of the limiting groove 282 faces the movable air outlet frame 25, and the limiting wind shield plate 281 is movably arranged in the corresponding limiting groove 282.

[0057] like Figure 1 and Figure 2 As shown, the air conditioner 100 further includes a switch door 3, which is slidably disposed on the housing 1 to open or close the air outlet 101. When the switch door 3 closes the air outlet 101, the air outlet device 2 is located inside the switch door 3. The switch door 3 can block the air outlet 101, thereby preventing dust or liquid from entering the housing 1, thereby playing a role in preventing dust and dust. At the same time, the switch door 3 shields the air outlet device 2 and other structures inside the housing 1, thereby making the appearance of the air conditioner 100 more beautiful.

[0058] like Figure 1 and Figure 2 As shown, the switch door 3 is arranged along the width direction of the air outlet 101 (such as Figure 2 The switch door 3 is movably arranged on the housing 1 in the left and right directions (as shown). When the switch door 3 closes the air outlet 101, the switch door 3 is located in the housing 1, and the housing 1 has a chamber for accommodating the switch door 3. Optionally, the shape of the switch door 3 matches the shape of the housing 1, for example, Figure 1 and Figure 2 In the example shown, the outer peripheral wall of the housing 1 at the air outlet 101 is arc-shaped, and the switch door 3 is an arc-shaped door.

[0059] Furthermore, a first motor for driving the switch door 3 to rotate may be provided in the shell 1, and a gear connected to the first motor may be provided in the shell 1. A rack cooperating with the gear may be provided on the switch door 3. The first motor drives the gear to rotate, and the gear drives the rack to move, thereby driving the switch door 3 to move, thereby realizing the opening and closing of the air outlet 101.

[0060] Furthermore, one of the switch door 3 and the housing 1 may be provided with a guide groove, and the other may be provided with a guide protrusion matched with the guide groove, so as to limit the movement trajectory of the switch door 3.

[0061] Furthermore, if Figure 1 and Figure 2 As shown, the switch door 3 has a first cavity 322 structure inside, thereby reducing the weight of the switch door 3, improving the structural strength of the switch door 3, and improving the heat insulation effect of the switch door 3. Specifically, the switch door 3 includes a first door body 31 and a second door body 32, both ends of the first door body 31 are connected to both ends of the second door body 32, the first door body 31 and the second door body 32 define a first cavity 322, and at least one of the first door body 31 and the second door body 32 is provided with a support rib 321 to support the first door body 31 and the second door body 32, thereby improving the structural strength of the switch door 3.

[0062] Alternatively, if Figure 6-Figure 8 As shown, the driving mechanism 29 includes an elastic member 291, such as a spring, one end of the elastic member 291 is connected to the fixed air outlet frame 21, and the other end of the elastic member 291 is connected to the movable air outlet frame 25 to drive the movable air outlet frame 25 to move from the first position shown to the second position. Figure 9-11 As shown, the switch door 3 abuts against the movable air outlet frame 25 during the process of closing the air outlet 101, so that when the switch door 3 closes the air outlet 101, the switch door 3 drives the movable air outlet frame 25 to move from the second position to the first position. Thus, the combination of the elastic member 291 and the switch door 3 can realize the movement of the movable air outlet frame 25 between the first position and the second position.

[0063] like Figure 1 and Fig. 9 As shown, the air conditioner 100 is in the off state, the switch door 3 closes the air outlet 101, the switch door 3 abuts against the movable air outlet frame 25 in the air outlet device 2, and the movable air outlet frame 25 is located in the first position under the action of the switch door 3; Figure 2 and Fig.10As shown, during the opening process of the switch door 3, since the switch door 3 will remain in contact with the movable air outlet frame 25, the movable air outlet frame 25 is still in the first position before the switch door 3 and the movable air outlet frame 25 are completely separated; Figure 3 and Fig.11 As shown, after the switch door 3 is completely separated from the movable air outlet frame 25, the movable air outlet frame 25 moves from the first position to the second position under the action of the elastic member 291, thereby extending the length of the air outlet duct of the entire air outlet device 2 and increasing the air supply distance. When the switch door 3 is closed, when the switch door 3 and the movable air outlet frame 25 are not in contact, the movable air outlet frame 25 is in the second position. When the switch door 3 and the movable air outlet frame 25 are in contact, the switch door 3 drives the movable air outlet frame 25 to move to the first position to avoid interference between the switch door 3 and the movable air outlet frame 25.

[0064] Furthermore, if Figure 6-Figure 8 As shown, the driving mechanism 29 also includes a first limit member 292 and a second limit member 293. The first limit member 292 is arranged on one of the fixed air outlet frame 21 and the movable air outlet frame 25. The first limit member 292 has a limit hole 2921. The second limit member 293 is passed through the limit hole 2921. One end of the second limit member 293 is connected to the other of the fixed air outlet frame 21 and the movable air outlet frame 25. A boss 2931 is provided on the outer peripheral wall of the other end of the second limit member 293. The cross-sectional area of ​​the boss 2931 is greater than the cross-sectional area of ​​the limit hole 2921. The elastic member 291 is located between one end of the first limit member 292 and the second limit member 293.

[0065] Among them, the second limiting member 293 is inserted into the limiting hole 2921 to play a guiding role. In addition, the boss 2931 is located on one side of the first limiting member 292, which can prevent the second limiting member 293 from escaping from the first limiting member 292. The elastic member 291 is arranged between the first limiting member 292 and one end of the second limiting member 293 to drive the movable air outlet frame 25 to move from the first position to the second position.

[0066] For example, in Figure 6-Figure 8 In the example shown, the driving mechanism 29 includes a first limiting member 292, a second limiting member 293 and an elastic member 291, the elastic member 291 is a spring, the first limiting member 292 is arranged on the fixed air outlet frame 21, the first limiting member 292 is provided with a limiting hole 2921, one end of the second limiting member 293 is connected to the movable air outlet frame 25, the second limiting member 293 is passed through the limiting hole 2921, and the other end of the second limiting member 293 is provided with a boss 2931, the cross-sectional area of ​​the boss 2931 is larger than the cross-sectional area of ​​the limiting hole 2921, the boss 2931 is located on the side of the first limiting member 292 away from the movable air outlet frame 25, and the elastic member 291 is sleeved on the second limiting member 293 and is located between the first limiting member 292 and the movable air outlet frame 25.

[0067] Furthermore, if Figure 6-Figure 8 , Figure 13-14 As shown, a first air guide strip 221 is provided at the downstream end of the first air duct 23, and a second air guide strip 261 is provided in the second air duct 27. The second air guide strip 261 is opposite to the first air guide strip 221, thereby improving the guiding effect on the airflow. The first stopper 292 is provided on one of the first air guide strip 221 and the second air guide strip 261, and the second stopper 293 is provided on the other of the first air guide strip 221 and the second air guide strip 261. This facilitates the fixing of the first stopper 292 and the second stopper 293.

[0068] Furthermore, if Figure 6-Figure 8 , Figure 13-14 As shown, the first air guide strip 221 is along the width direction of the first air duct 23 (such as Figure 6 The second air guide strips 261 are spaced apart in the width direction of the second air duct 27 (as shown in the left and right directions). Figure 6 There are multiple elastic members 291 spaced apart from each other (in the left and right direction as shown), multiple first air guide strips 221 and multiple second air guide strips 261 correspond one to one, each first air guide strip 221 is provided with a first limiting member 292, each second air guide strip 261 is provided with a second limiting member 293 that cooperates with the first limiting member 292 on the corresponding first air guide strip 221, and there are multiple elastic members 291, and multiple elastic members 291 correspond one to one with multiple first limiting members 292 and multiple second limiting members 293.

[0069] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0070] Furthermore, each first air guide strip 221 is provided with a plurality of first limit members 292 spaced apart along the length direction of the first air guide strip 221, and each second air guide strip 261 is provided with a plurality of second limit members 293 spaced apart along the length direction of the second air guide strip 261. The corresponding plurality of first limit members 292 on the first air guide strip 221 and the plurality of second limit members 293 on the second air guide strip 261 correspond one to one.

[0071] In some embodiments of the present invention, Figure 9-11 As shown, a rolling member 294 is provided on one of the switch door 3 and the movable air outlet frame 25, and the outer peripheral wall of the rolling member 294 abuts against the other of the switch door 3 and the movable air outlet frame 25. Thus, the friction between the switch door 3 and the movable air outlet frame 25 can be reduced, and when the switch door 3 is closed, the switch door 3 can drive the movable air outlet frame 25 to move from the second position to the first position.

[0072] For example, in Figure 9-11In the example shown, both ends of the movable air outlet frame 25 in the width direction are respectively provided with rolling members 294, and a limiting rib 33 extending along the moving direction of the switch door 3 is provided on the side of the switch door 3 facing the inside of the housing 1, and the limiting rib 33 abuts against the outer peripheral wall of the rolling member 294. This facilitates the abutment between the movable air outlet frame 25 and the switch door 3, and facilitates the switch door 3 to drive the movable air outlet frame 25 to move from the second position to the first position when the switch door 3 is closed.

[0073] like Figure 3 As shown, the movable air outlet frame 25 is in the second position, and when the center line of the second air duct 27 is perpendicular to the plane where the air outlet 101 is located, the downstream end of the movable air outlet frame 25 exceeds the plane where the air outlet 101 is located. Figure 4 and Figure 5 As shown, at least a portion of the movable air outlet frame 25 can be extended out of the plane where the air outlet 101 is located, so that the air supply range of the air conditioner 100 can be increased, and the swing air supply range of the air outlet device 2 can reach 120°.

[0074] It should be noted that the plane where the air outlet 101 is located is a plane defined by two opposite straight sides of the air outlet 101. Figure 3 In the example shown, the length direction of the air outlet 101 (eg Fig.12 The two edges of the air outlet 101 in the vertical direction (such as Fig.12 The two edges of the air outlet 101 (in the left and right directions as shown) are straight edges, and the plane where the air outlet 101 is located is a plane defined by the two straight edges in the width direction of the air outlet 101.

[0075] In some embodiments of the present invention, Figure 6-Figure 8 As shown, along the airflow direction, the first air duct 23 has a first end 231 and a second end 232, and the first end 231 is located upstream of the second end 232. The air outlet device 2 also includes a first air outlet grille 22 and a louver 24. The first air outlet grille 22 is arranged in the first air duct 23 and is located at the second end 232. The louver 24 is rotatably arranged in the first air duct 23. The rotation direction of the louver 24 is perpendicular to the rotation direction of the fixed air outlet frame 21. Along the airflow direction, the louver 24 is located upstream of the air outlet grille. On the one hand, the first air outlet grille 22 can play a role in guiding the air. On the other hand, the first air outlet grille 22 can also play a protective role to prevent the user from getting injured by putting his hand into the air duct. In addition, the first air outlet grille 22 and the louver 24 can realize the air supply of the air conditioner 100 in two dimensions, and realize the three-dimensional air supply of the air conditioner 100.

[0076] Furthermore, if Fig.12As shown, there are multiple louvers 24, and the multiple louvers 24 are spaced apart along the extension direction of the rotating shaft of the fixed air outlet frame 21. The air outlet device 2 also includes a connecting rod 241, which is rotatably connected to the multiple louvers 24 so that the multiple louvers 24 rotate synchronously.

[0077] Furthermore, the extension direction of the rotation axis of the fixed air outlet frame 21 is aligned with the length direction of the air outlet 101 (eg Fig.12 It is understood that the fixed air outlet frame 21 can be fixed in the width direction of the air outlet 101 (such as Figure 1 The first air outlet grille 22 includes a plurality of first air guide strips 221, which are arranged along the width direction of the first air duct 23 (as shown in the left and right directions). Figure 6 Each first air guide strip 221 is spaced apart along the length direction of the air outlet 101 (as shown in the left and right directions). Fig.12 The first air guide strip 221 extends in the vertical direction as shown, and each first air guide strip 221 is parallel to the center line of the first air duct 23. Thus, the air guide effect of the first air outlet grille 22 can be increased.

[0078] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0079] like Figure 6-Figure 8 As shown, a second air outlet grille 26 is provided in the second air duct 27. The second air outlet grille 26 includes a plurality of second air guide strips 261, which are arranged along the width direction of the second air duct 27 (eg Figure 6 Each second air guide strip 261 is spaced apart along the length direction of the air outlet 101 (as shown in the left and right directions). Fig.12 The second air guide strips 261 extend in the vertical direction as shown, and each second air guide strip 261 is parallel to the center line of the second air duct 27, and the plurality of second air guide strips 261 correspond one to one to the plurality of first air guide strips 221. Thus, the air guide effect of the second air outlet grille 26 can be increased.

[0080] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the extending direction of the rotation axis of the fixed air outlet frame 21 is the same as the length direction of the air outlet 101, and the width direction of the fixed air outlet frame 21 (such as Figure 1 The two outer walls of the fixed air outlet frame 21 (in the left and right directions shown) are spaced apart from the inner peripheral wall of the air outlet 101. Thus, an air outlet gap can be defined between the outer wall of the fixed air outlet frame 21 and the inner peripheral wall of the air outlet 101, which can avoid condensation due to inconsistent temperatures inside and outside the fixed air outlet frame 21. Figure 6As shown, the two outer side walls of the fixed air outlet frame 21 in the width direction are arc-shaped surfaces to guide the airflow to flow toward the center of the air outlet 101. In this way, the airflow flowing out from the two outer side walls of the fixed air outlet frame 21 in the width direction and the inner peripheral wall of the air outlet 101 can flow toward the air outlet 101, mix with the air flowing out of the first air duct 23 and blow into the room, thereby increasing the air supply volume and air supply distance.

[0081] Furthermore, if Figure 6 As shown, the width direction of the fixed air outlet frame 21 (such as Figure 6 The two outer side walls (in the left and right directions shown) are arc-shaped surfaces convex in the direction away from the first air duct 23. Thus, the airflow flowing out from the gap between the two outer side walls in the width direction of the fixed air outlet frame 21 and the inner peripheral wall of the air outlet 101 can flow toward the center of the air outlet 101 better.

[0082] In some embodiments of the present invention, Figure 6 As shown, the fixed air outlet frame 21 includes a first air duct 23 in the width direction (such as Figure 6 The first side plate 211 and the second side plate 212 are spaced apart in the left-right direction (as shown in the figure), and at least one of the first side plate 211 and the second side plate 212 has a cavity 2121, and the cavity 2121 extends along the length direction of the fixed air outlet frame 21. In this way, the heat insulation effect of the first side plate 211 and the second side plate 212 can be improved. Further, the cavity 2121 extends along the length direction (as shown in the figure) of the corresponding first side plate 211 or the second side plate 212. Fig.12 Thus, the heat insulation effect of the first side plate 211 and the second side plate 212 can be further improved.
