The examples of the embodiments are shown in the 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 drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0035] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the drawings.

[0036] As Figure 1 shown, the air conditioner 100 according to an embodiment of the present invention includes a housing 1 and an air outlet frame assembly 2.

[0037] Specifically, as Figure 1 shown, the housing 1 has an air outlet 101, the housing 1 also has an air inlet 102, an air duct 113 is defined inside the housing 1, both ends of the air duct 113 are respectively communicated with the air inlet 102 and the air outlet 101, an air impeller 4 is arranged inside the air duct 113, the air impeller 4 is rotatably arranged inside the air duct 113, a heat exchanger 5 is also arranged inside the housing 1, and the heat exchanger 5 is opposite to the air inlet 102. Under the action of the air impeller 4, the air flow enters from the air inlet 102, the air flow entering the housing 1 exchanges heat with the heat exchanger 5, and the air flow after heat exchange is discharged from the air outlet 101 into the room, thereby realizing the cooling or heating of the room.

[0038] In Figure 1In the illustrated example, the housing 1 is formed in a columnar shape. The air inlet 102 and the air outlet 101 are both provided on the outer peripheral wall of the housing 1, and the air inlet 102 and the air outlet 101 are oppositely arranged. The air inlet 102 and the air outlet 101 both extend in the up and down direction, and the air wheel 4 extends in the up and down direction (such as Figure 8 the up and down direction shown).

[0039] As Figure 1 and Figure 2 shown, the air outlet frame assembly 2 includes an air outlet frame 21 and an air outlet grille 22. The air outlet frame 21 is rotatably provided at the air outlet 101. The air outlet frame 21 has an air outlet passage 23, and the air outlet grille 22 is provided at one end of the air outlet passage 23. On the one hand, the air outlet grille 22 can play a role in guiding the air. On the other hand, the air outlet grille 22 can also play a role in protection, preventing the user's hand from reaching into the air duct 113 and getting injured.

[0040] As Figure 3 shown, the air outlet frame 21 has a first position. In the first position, the axis of the air outlet passage 23 is perpendicular to the plane where the air outlet 101 is located. Along the flowing direction of the air flow, the air outlet grille 22 is located at the downstream end of the air outlet passage 23, and the outer surface of the air outlet grille 22 extends beyond the plane where the air outlet 101 is located.

[0041] Among them, it should be noted that the plane where the air outlet 101 is located is the plane defined by the two opposite straight edges of the air outlet 101. In Figure 3 the illustrated example, the two edges in the length direction of the air outlet 101 (such as Figure 8 the up and down direction described) are arc-shaped edges, and the two edges in the width direction of the air outlet 101 (such as Figure 3 the left and right direction shown) are straight edges. The plane where the air outlet 101 is located is the plane defined by the two straight edges in the width direction of the air outlet 101.

[0042] In addition, it should be noted that the outer surface of the air outlet grille 22 is the surface defined by the outer ends of the plurality of air guiding strips 221 of the air outlet grille 22.

[0043] Thus, as Figures 3 - 5 shown, the air outlet grille 22 can extend out of the air outlet 101. When the air outlet frame 21 swings to supply air, such as Figures 3 - 5 the left and right swing to supply air shown, it can ensure that at least a part of the air outlet grille 22 extends out of the air outlet 101, which is beneficial to increasing the air supply range, such as Figure 3 the left and right air supply range shown. And since the outer surface of the air outlet grille 22 extends beyond the plane where the air outlet 101 is located, the length of the air duct 113 is extended, and the air supply distance can be increased.

[0044] According to the air conditioner 100 of an embodiment of the present invention, by making the air outlet frame 21 in the first position, the outer surface of the air outlet grille 22 exceeds the plane where the air outlet 101 is located, it can be ensured that at least a part of the air outlet grille 22 extends out of the air outlet 101 when swinging and blowing air, which is beneficial to increasing the air supply range of the air conditioner 100 and can improve the air supply distance.

[0045] As Figure 1 and Figure 2 shown, the air conditioner 100 further includes a switch door 3. The switch door 3 is movably arranged 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 frame assembly 2 is located inside the switch door 3. The switch door 3 can block the air outlet 101, preventing dust or liquid from entering the interior of the housing 1, playing a role in dust prevention and ash prevention. At the same time, the switch door 3 covers the air outlet frame 21 structure and other structures inside the housing 1, making the appearance of the air conditioner 100 more beautiful.

[0046] As Figure 1 and Figure 2 shown, the switch door 3 is movably arranged on the housing 1 along the width direction of the air outlet 101 (such as the left - right direction shown in Figure 2 ). When the switch door 3 closes the air outlet 101, the switch door 3 is located inside the housing 1, and there is a chamber in the housing 1 for accommodating the switch door 3. Optionally, the shape of the switch door 3 matches the shape of the housing 1. For example, in the examples shown in Figure 1 and Figure 2 , 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.

[0047] Further, a first motor for driving the switch door 3 to rotate can be arranged inside the housing 1. A gear connected to the first motor is also arranged inside the housing 1. A rack cooperating with the gear can be arranged 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, and then realizing the opening and closing of the air outlet 101.

[0048] Furthermore, a guide groove can be arranged on one of the switch door 3 and the housing 1, and a guide protrusion cooperating with the guide groove can be arranged on the other, so as to define the movement track of the switch door 3.

[0049] Still further, as Figure 1 and Figure 2As shown, the switch door 3 has a first cavity 322 structure inside, which can reduce the weight of the switch door 3, improve the structural strength of the switch door 3, and also improve 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. The two ends of the first door body 31 are connected to the two ends of the second door body 32. The first door body 31 and the second door body 32 define the first cavity 322. 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.

[0050] Furthermore, as Figure 1 and Figure 2 shown, the air outlet frame 21 has a second position. In the second position, the axis of the air outlet channel 23 is perpendicular to the plane where the air outlet 101 is located. Along the flow direction of the air flow, the air outlet grille 22 is located at the upstream end of the air outlet channel 23. When the switch door 3 closes the air outlet 101, the air outlet frame 21 is located at the second position. It can be understood that in the air supply state, along the air flow direction, the air outlet grille 22 can be located at the downstream end of the air outlet channel 23, which is beneficial for guiding the air. In the shutdown state, along the air flow direction, the air outlet grille 22 can be located at the upstream end of the air outlet channel 23, and the air outlet frame 21 can rotate so that the air outlet grille 22 rotates to the upstream end of the air outlet channel 23. In the startup state, when the air outlet frame 21 is located at the first position, when the air conditioner 100 is in the shutdown state, the air outlet frame 21 can rotate 180° so that the air outlet frame 21 rotates to the second position.

[0051] As Figure 3 shown, along the extension direction of the air outlet channel 23, the maximum distance between the rotation axis of the air outlet frame 21 and the end of the air outlet frame assembly 2 provided with the air outlet grille 22 is L1, and the maximum distance between the rotation axis of the air outlet frame 21 and the end of the air outlet frame assembly 2 away from the air outlet grille 22 is L2, and L2 < L1 is satisfied. This can make the air outlet frame assembly 2 in an eccentric rotation state, so that in the shutdown state, the end of the air outlet frame assembly 2 away from the air outlet grille 22 does not protrude from the air outlet 101 or protrudes from the air outlet 101 with a small length, which is convenient for the switch door 3 to close the air outlet 101, avoiding interference between the switch door 3 and the air outlet frame assembly 2. At the same time, the switch door 3 can be set closer to the center of the housing 1, reducing the volume of the air conditioner 100 and increasing the aesthetic appearance of the air conditioner 100.

[0052] Optionally, L1 and L2 satisfy: 0.27L1 ≤ L2 ≤ 0.7L1. Among them, L2 can be 0.3L1, 0.4L1, 0.5L1, 0.6L1, etc. Preferably, L2 is 0.5L1. Thus, the air outlet frame assembly 2 can be eccentrically arranged, so that in the off state, the end of the air outlet frame assembly 2 away from the air outlet grille 22 does not protrude from the air outlet 101 or the protruding length from the air outlet 101 is small, which is convenient for the switch door 3 to close the air outlet 101, avoiding interference between the switch door 3 and the air outlet frame assembly 2. At the same time, the switch door 3 can be arranged closer to the center of the housing 1, reducing the volume of the air conditioner 100 and increasing the aesthetic appearance of the air conditioner 100.

[0053] Furthermore, as Figure 1 and Figure 2 shown, in the second position, the end of the air outlet frame assembly 2 away from the air outlet grille 22 extends beyond the plane where the air outlet 101 is located. Thus, it can be ensured that the air outlet frame 21 can extend beyond the plane where the air outlet 101 is located in the second position, which is beneficial to improving the air supply range.

[0054] As Figure 3 、 Figure 6 and Figure 7 shown, the extending direction of the rotation axis of the air outlet frame 21 is the same as the length direction of the air outlet 101 (such as the up and down direction shown in Figure 8 ). It can be understood that the air outlet frame 21 can swing in the width direction of the air outlet 101 (such as the left and right direction shown in Figure 3 ). The air outlet grille 22 includes a plurality of air guiding strips 221. The plurality of air guiding strips 221 are spaced apart along the width direction of the air outlet passage 23 (such as the left and right direction shown in Figure 3 ). Each air guiding strip 221 extends along the length direction of the air outlet 101 (such as the up and down direction shown in Figure 8 ), and each air guiding strip 221 is parallel to the center line of the air outlet passage 23. Thus, the air guiding effect of the air outlet grille 22 can be increased.

[0055] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0056] Further, as Figure 3 shown, in the first position, along the air flow direction, the downstream ends of the plurality of air guiding strips 221 are flush, and the outer surface of the air outlet grille 22 is a plane formed by the connection lines of the downstream ends of the plurality of air guiding strips 221. Of course, the downstream ends of the plurality of air guiding strips 221 may not be flush.

[0057] Furthermore, as Figure 3As shown, the lengths of multiple air guide strips 221 along the air flow direction are the same, that is, at the first position, the upstream ends of the multiple air guide strips 221 are also flush. Among them, along the air flow direction, the thicknesses of the multiple air guide strips 221 are the same. Of course, along the air flow direction, the thicknesses of the multiple air guide strips 221 can first increase and then decrease, or at the first position, the thicknesses of the multiple air guide strips 221 gradually increase.

[0058] In addition, as Figure 6 and Figure 7 shown, the air outlet grille 22 further includes connecting ribs 222. The connecting ribs 222 extend along the width direction of the air outlet channel 23 (such as Figure 3 the left-right direction shown), and the connecting ribs 222 are connected to the multiple air guide strips 221, thereby increasing the structural strength of the air outlet grille 22. Optionally, there are multiple connecting ribs 222, and the multiple connecting ribs 222 are spaced apart along the length direction of the air outlet channel 23 (such as Figure 8 the up-down direction shown).

[0059] As Figure 3 and Figure 7 shown, the air outlet frame assembly 2 further includes louvers 24. The louvers 24 are rotatably arranged in the air outlet channel 23, and the rotation direction of the louvers 24 is perpendicular to the rotation direction of the air outlet frame 21. Thus, the combination of the louvers 24, the air outlet frame 21, and the air outlet grille 22 can achieve air supply in two dimensions and realize three-dimensional air supply. Further, when the air outlet frame 21 is in the first position, along the air flow direction, the louvers 24 are located upstream of the air outlet grille 22. This can make the structure of the air outlet frame assembly 2 more compact.

[0060] Further, there are multiple louvers 24, and the multiple louvers 24 are spaced apart along the direction perpendicular to the rotation axis of the louvers 24, that is, the direction of the rotation axis of the air outlet frame 21. The air outlet frame assembly 2 further includes a connecting rod 25, and the connecting rod 25 is rotatably connected to the multiple louvers 24 to make the multiple louvers 24 rotate synchronously.

[0061] In the description of the present invention, unless otherwise specified, the meaning of "multiple" is two or more.

[0062] Further, as Figure 3 shown, both ends of the louver 24 in the width direction (such as Figure 3 the left-right direction shown) are spaced apart from the inner wall of the air outlet channel 23, and along the air flow direction, the gaps between the louver 24 and the inner wall of the air outlet channel 23 are the same. This facilitates the air guiding of the louver 24.

[0063] In some embodiments of the present invention, as Figures 2 - 5 shown, the air outlet frame 21 further has a second position and a third position. At the second position, as Figure 2As shown, the axis of the air outlet passage 23 is perpendicular to the plane where the air outlet 101 is located. Along the air flow direction, the air outlet grille 22 is located at the upstream end of the air outlet passage 23. At the third position, such as Figure 4 or Figure 5 As shown in the position, along the air flow direction, the air outlet grille 22 is located at the downstream of the air outlet passage 23. The air outlet grille 22 rotates between the third position and the second position, and the first position is between the third position and the second position. Such as Figure 6 As shown, a first limiting post 26 is provided on the air outlet frame 21, and spaced second limiting posts 103 and third limiting posts 104 are provided on the housing 1. When the air outlet frame 21 is in the second position, the first limiting post 26 cooperates with the second limiting post 103. When the air outlet frame 21 is in the third position, the first limiting post 26 cooperates with the third limiting post 104. Thus, the air outlet frame 21 can rotate between the second position and the third position, improving the working reliability of the air outlet frame 21.

[0064] For example, in Figures 2 - 5 In the shown example, the air outlet frame 21 has a first position, a second position, a third position and a fourth position, and the air conditioner 100 rotates between the second position and the third position: at the first position, such as Figure 3 As shown, the axis of the air outlet passage 23 is perpendicular to the plane where the air outlet 101 is located. Along the air flow direction, the air outlet grille 22 is located at the downstream end of the air outlet passage 23; at the second position, such as Figure 2 As shown, the axis of the air outlet passage 23 is perpendicular to the plane where the air outlet 101 is located. Along the air flow direction, the air outlet grille 22 is located at the upstream end of the air outlet passage 23; at the third position, such as Figure 5 As shown in the position, along the air flow direction, the air outlet grille 22 is located at the downstream of the air outlet passage 23, and the first position is between the third position and the second position; at the fourth position, such as Figure 4 As shown in the position, along the air flow direction, the air outlet grille 22 is located at the downstream of the air outlet passage 23, and the fourth position is between the first position and the second position. At the third position, the air conditioner 100 realizes forward air supply. At the third position, the air conditioner 100 realizes right air supply. At the fourth position, the air conditioner 100 realizes left air supply.

[0065] In the present invention, by making the air outlet frame 21 in the first position and the outer surface of the air outlet grille 22 exceeding the plane where the air outlet 101 is located, the angle between the air outlet directions of the air outlet frame 21 at the third position and the fourth position can be made larger, and the air supply angle can reach 145 degrees.

[0066] Optionally, such as Figure 3 As shown, the extending direction of the rotation axis of the air outlet frame 21 is the same as the length direction of the air outlet 101 (such as Figure 8 The up and down direction shown), the width direction of the air outlet frame 21 (such asFigure 3 The two outer side walls in the left - right direction (as 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 side wall of the air outlet frame 21 and the inner peripheral wall of the air outlet 101, which can avoid the condensation phenomenon caused by inconsistent temperatures on both the inner and outer sides of the air outlet frame 21. Further, as Figure 3 shown, the two outer side walls in the width direction of the air outlet frame 21 are arc - shaped surfaces to guide the air flow towards the direction close to the center of the air outlet 101. Thus, the air flow flowing out from between the two outer side walls in the width direction of the air outlet frame 21 and the inner peripheral wall of the air outlet 101 can flow towards the air outlet 101, and be mixed with the air flowing out from the air outlet passage 23 and blown into the room, improving the air supply volume and the air supply distance.

[0067] In Figure 3 the example shown, the two outer side walls in the width direction of the air outlet frame 21 (such as the left - right direction as shown in Figure 3 ) are both arc - shaped surfaces protruding away from the air outlet passage 23. Thus, the air flow flowing out from the gap between the two outer side walls in the width direction of the air outlet frame 21 and the inner peripheral wall of the air outlet 101 can flow better towards the center of the air outlet 101.

[0068] In some embodiments of the present invention, as shown in Figure 3 , at the first position, the width of the upstream end of the air outlet passage 23 is greater than the width of the downstream end of the air outlet passage 23. Thus, the air blown out from the air outlet passage 23 can be more concentrated, improving the air supply distance. In addition, in the startup and forward air supply states, the air outlet frame 21 can also be located at the second position. At this time, the width of the air outlet end of the air outlet passage 23 is greater than the width of the air inlet end, which can make the air blown out from the air outlet passage 23 softer, meeting different needs of users.

[0069] Specifically, as shown in Figure 3 , at the first position, along the air flow direction, the air outlet passage 23 includes a first section 231 and a second section 232. The width of the first section 231 gradually decreases along the air flow direction, and the width of the second section 232 is the same along the air flow direction. Thus, the structure and processing technology of the air outlet frame 21 can be simplified, improving the production efficiency.

[0070] In addition, as shown in Figure 3 , Figure 6 and Figure 7As shown, the air outlet frame 21 includes opposite first side plates 211 and second side plates 212. The first side plates 211 and the second side plates 212 are located at both ends in the width direction of the air outlet passage 23. Both the first side plates 211 and the second side plates 212 are spaced apart from the inner wall of the air outlet 101. At least one of the first side plates 211 and the second side plates 212 has a second cavity 2121. Thereby, the heat insulation effect of the first side plates 211 and the second side plates 212 can be improved. Further, the second cavity 2121 extends along the length direction of the corresponding first side plate 211 or second side plate 212 (such as Figure 7 the up-down direction shown). Thereby, the heat insulation effect of the first side plates 211 and the second side plates 212 can be further improved.

[0071] As Figure 6 and Figure 7 shown, the air outlet frame 21 further includes a top plate 213 and a bottom plate 214. The top plate 213 is connected to one end in the length direction of the first side plates 211 and the second side plates 212, and the bottom plate 214 is connected to the other end in the length direction of the first side plates 211 and the second side plates 212. The top plate 213, the first side plates 211, the second side plates 212, and the bottom plate 214 jointly define the air outlet passage 23. The shapes of the first side plates 211 and the second side plates 212 are symmetrical, and the shapes of the top plate 213 and the bottom plate 214 are the same. As Figure 3 shown, the projections of the air outlet grille 22 and the louvers 24 in a plane parallel to the top plate 213 and the bottom plate 214 are both located within the projections of the top plate 213 and the bottom plate 214 in a plane parallel to it. At this time, the maximum distance between the end of the air outlet frame assembly 2 away from the air outlet grille 22 and the rotation axis of the air outlet frame 21 is the maximum distance between the end of the air outlet frame 21 away from the air outlet grille 22 and the rotation axis of the air outlet frame 21. Additionally, as Figure 3 shown, one end of the air outlet grille 22 is flush with the corresponding ends of the top plate 213 and the bottom plate 214 of the air outlet frame 21. The maximum distance between the end of the air outlet frame assembly 2 close to the air outlet grille 22 and the rotation axis of the air outlet frame 21 is the maximum distance between the end of the air outlet frame 21 close to the air outlet grille 22 and the rotation axis of the air outlet frame 21.

The rear housing 106 and the front housing 105 are both disposed on the base 108. The front housing 105 and the rear housing 106 are connected. The top cover 107 is connected to both the front housing 105 and the rear housing 106. A panel bracket 110 is disposed inside the front housing 105. A duct member 109 for defining a duct 113 is also provided inside the housing 1. Among them, an air outlet 101 is provided on the front housing 105, and an air inlet 102 is provided on the rear housing 106. An upper driving assembly 111 and a lower driving assembly 112 for supporting and driving the air outlet frame 21 to rotate are disposed on the panel bracket 110. A second limiting post 103 and a third limiting post 104 are disposed on the lower driving assembly 112.
