[0033] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0034] In the description of the present invention, it should 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 the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying 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 operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] The following describes an air outlet frame assembly 2 and an air conditioner 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the air outlet frame assembly 2 according to an embodiment of the present invention includes an air outlet frame 21.

[0037] like Figure 1 、 Figure 2 and Figure 5 As shown, the air outlet frame 21 is rotatably arranged at the air outlet 101 of the air flow channel 113. The air outlet frame 21 has an air outlet channel 23. Along the air flow direction, the air outlet channel 23 has a first end 231 and a second end 232. The cross-sectional area of ​​the first end 231 is larger than the cross-sectional area of ​​the second end 232.

[0038] Thus, the air outlet frame 21 can be rotated so that the first end 231 is located upstream of the second end 232 or the second end 232 is located upstream of the first end 231 along the air flow direction. Figure 3 As shown, when the first end 231 is located upstream of the second end 232, since the cross-sectional area of ​​the second end 232 is smaller than the cross-sectional area of ​​the first end 231, it can achieve the effect of gathering wind, thereby achieving the purpose of increasing the air supply speed and air supply distance; Figure 4 As shown, when the second end 232 is located upstream of the first end 231, since the cross-sectional area of ​​the first end 231 is larger than the cross-sectional area of ​​the second end 232, it can diffuse the wind, thereby achieving the purpose of slowing down the wind speed and making the wind smooth.

[0039] According to the air outlet frame assembly 2 of the embodiment of the present invention, the air outlet frame 21 is rotatably provided at the air outlet 101, and the cross-sectional area of ​​the first end 231 of the ground air outlet channel 23 is made larger than the cross-sectional area of ​​the second end 232. By adjusting the positional relationship between the first end 231 and the second end 232 in the flow direction of the airflow, the purpose of increasing the air supply speed and the air supply distance or achieving the purpose of slowing down the wind speed and smoothing the air outlet can be achieved, thereby meeting the different needs of users.

[0040] Further, if Figure 5As shown, the cross-sectional area of ​​the air outlet channel 23 gradually decreases from the first end 231 to the second end 232. This can achieve a better airflow guidance effect, so that the airflow has a better wind gathering effect or diffusion effect, and at the same time can reduce the noise during the airflow process.

[0041] Alternatively, as Figure 5 As shown, along the airflow direction, the length of the air outlet channel 23 (as shown in FIG. Figure 6 The length in the vertical direction shown in FIG) is the same, and the width of the first end 231 (as shown in FIG) is the same Figure 5 The width of the air outlet channel 23 (shown in the left-right direction) is greater than the width of the second end 232, and the width of the air outlet channel 23 gradually decreases in the direction from the first end 231 to the second end 232. This allows the cross-sectional area of ​​the first end 231 to be greater than the cross-sectional area of ​​the second end 232, and the cross-sectional area of ​​the air outlet channel 23 to gradually decrease in the direction from the first end 231 to the second end 232. This helps simplify the structure and processing of the air outlet frame 21, and can achieve better airflow guidance, so that the airflow has a better wind gathering or diffusion effect, and can also reduce noise during the flow of air.

[0042] Of course, the present invention is not limited to this. Along the direction of air flow, the width of the air outlet channel 23 can be the same, the length of the first end 231 is greater than the length of the second end 232, and the length of the air outlet channel 23 gradually decreases in the direction from the first end 231 to the second end 232.

[0043] Furthermore, if Figure 5 As shown, at least one of the two side walls in the width direction of the air outlet channel 23 is an arcuate surface or a flat surface. This simplifies the structure of the air outlet frame 21 and increases the guiding effect of the air outlet channel 23 side walls on the airflow, thereby reducing noise during the airflow process.

[0044] Preferably, at least one of the two side walls of the air outlet channel 23 in the width direction is an arc-shaped surface, wherein the arc-shaped surface is an arc-shaped surface convex toward the inside of the air outlet channel 23 .

[0045] For example, in Figure 5 In the example shown, both side walls of the air outlet channel 23 in the width direction are arc-shaped surfaces convex toward the inside of the air outlet channel 23 .

[0046] In some embodiments of the present invention, Figure 5 As shown, the extension direction of the rotation axis of the air outlet frame 21 is aligned with the length direction of the air outlet 101 (as shown in FIG. Figure 6 The width direction of the air outlet frame 21 (as shown in the upper and lower directions) is the same. Figure 5The two outer walls (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 air outlet frame 21 and the inner peripheral wall of the air outlet 101, which can avoid condensation caused by inconsistent temperatures inside and outside the air outlet frame 21. Figure 5 As shown, the two outer side walls of the air outlet frame 21 in the width direction are arc-shaped surfaces to guide the air flow toward the center of the air outlet 101. As a result, the air flowing out from between the two outer side walls of the air outlet frame 21 in the width direction and the inner peripheral wall of the air outlet 101 flows toward the air outlet 101, mixes with the air flowing out of the air outlet channel 23 and is blown into the room, thereby increasing the air supply volume and air supply distance.

[0047] Furthermore, if Figure 5 As shown, the width direction of the air outlet frame 21 (as shown Figure 5 The two outer walls (in the left and right directions shown) are arc-shaped surfaces that bulge away from the air outlet channel 23. This allows the air flowing out of the gap between the two outer walls in the width direction of the air outlet frame 21 and the inner peripheral wall of the air outlet 101 to flow better toward the center of the air outlet 101.

[0048] In some embodiments of the present invention, Figure 5 As shown, the air outlet frame 21 includes a width direction of the air outlet channel 23 (such as Figure 5 The first side plate 211 and the second side plate 212 are spaced apart in the left and right directions (as shown in the left and right directions), and at least one of the first side plate 211 and the second side plate 212 has a cavity 2121, which extends along the length direction of the air outlet frame 21. This can improve the heat insulation effect of the first side plate 211 and the second side plate 212. Further, the cavity 2121 extends along the length direction of the corresponding first side plate 211 or the second side plate 212 (as shown in the left and right directions). Figure 6 Thus, the heat insulation effect of the first side plate 211 and the second side plate 212 can be further improved.

[0049] like Figure 6 As shown, the air outlet frame 2121 further includes a top plate 213 and a bottom plate 214. The top plate 213 is aligned with the first side plate 211 and the second side plate 212 in the length direction (as shown in FIG. Figure 6 The top plate 213, the first side plate 211, the second side plate 212 and the bottom plate 214 together define an air outlet channel 23. The first side plate 211 and the second side plate 212 are symmetrical in shape, and the top plate 213 and the bottom plate 214 have the same shape.

[0050] In some embodiments of the present invention, Figure 5As shown, the air outlet frame assembly 2 further includes an air outlet grille 22, which is disposed in the air outlet channel 23 and located at the second end 232. The air outlet grille 22 can guide the air on the one hand, and on the other hand, it can also protect the user from getting injured by inserting his hand into the air flow channel 113.

[0051] like Figure 3 As shown, the air outlet frame 21 has a first position. In the first 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 airflow, the air outlet grille 22 is located at the downstream end of the air outlet channel 23, and the outer surface of the air outlet grille 22 exceeds the plane where the air outlet 101 is located.

[0052] It should be noted that the plane where the air outlet 101 is located is the plane defined by the two opposite straight sides of the air outlet 101. Figure 3 In the example shown, the length direction of the air outlet 101 (eg Figure 6 The two edges of the upper and lower directions are arc-shaped edges, and the width direction of the air outlet 101 (such as Figure 3 The two edges (in the left and right directions 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.

[0053] In addition, it should be noted that the outer surface of the air outlet grille 22 refers to a surface defined by outer ends of the plurality of air guide strips 221 of the air outlet grille 22 .

[0054] Furthermore, if Figure 4 As 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 of the air outlet 101. The air outlet grille 22 is located at the upstream end of the air outlet channel 23 along the direction of airflow. When the door 3 closes the air outlet 101, the air outlet frame 21 is in the second position. It is understood that in the air supply state, the air outlet grille 22 can be located at the downstream end of the air outlet channel 23 along the direction of airflow, which can facilitate air guidance. In the off state, the air outlet grille 22 can be located at the upstream end of the air outlet channel 23 along the direction of airflow. 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 on state, when the air outlet frame 21 is in the first position, when the air conditioner 100 is off, the air outlet frame 21 can rotate 180° so that the air outlet frame 21 rotates to the second position.

[0055] like Figure 3As 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 allows the air outlet frame assembly 2 to be in an eccentric rotation state, so that when the air outlet frame assembly 2 is off, the end away from the air outlet grille 22 does not extend out of the air outlet 101 or extends out of the air outlet 101 by a small distance, making it easier for the switch door 3 to close the air outlet 101 and avoiding interference between the switch door 3 and the air outlet frame assembly 2. At the same time, the switch door 3 can be placed closer to the center of the housing 1, reducing the volume of the air conditioner 100 and improving the appearance of the air conditioner 100.

[0056] Furthermore, if Figure 1 and Figure 2 As shown, in the second position, the end of the air outlet frame assembly 2 away from the air outlet grille 22 exceeds the plane where the air outlet 101 is located. Thus, it can be ensured that the air outlet frame 21 can extend out of the plane where the air outlet 101 is located in the second position, thereby facilitating the improvement of the air supply range.

[0057] Furthermore, if Figure 6 As shown, the extension direction of the rotation axis of the air outlet frame 21 is aligned with the length direction of the air outlet 101 (as shown in FIG. Figure 6 It is understood that the air outlet frame 21 can be in the width direction of the air outlet 101 (such as Figure 1 The air outlet grille 22 includes a plurality of air guide strips 221, which are arranged along the width direction of the air outlet channel 23 (as shown in the left and right directions). Figure 5 The left and right directions shown in FIG are spaced apart, and each air guide strip 221 is spaced apart along the length direction of the air outlet 101 (as shown in FIG Figure 6 The air guide strips 221 extend in the vertical direction as shown, and each air guide strip 221 is parallel to the center line of the air outlet channel 23. This can increase the air guide effect of the air outlet grille 22.

[0058] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0059] Furthermore, if Figure 5 As shown, along the airflow direction, when the second end 232 is located downstream of the first end 231, the downstream ends of the plurality of air guide strips 221 are aligned. Of course, the downstream ends of the plurality of air guide strips 221 may not be aligned.

[0060] Furthermore, if Figure 5 As shown, the length of the plurality of air guide strips 221 along the air flow direction (eg Figure 5 The length in the front-to-back direction is the same as shown. Figure 5 Of course, along the direction of air flow, the thickness of the plurality of air guide strips 221 may first increase and then decrease, or along the direction of air flow, when the second end 232 is located downstream of the first end 231, the thickness of the plurality of air guide strips 221 gradually increases.

[0061] In addition, if Figure 6 As shown, the air outlet grille 22 further includes a connecting rib 222, which extends along the width direction of the air outlet channel 23 (eg Figure 5 The connecting ribs 222 are connected to the plurality of air guide strips 221, thereby increasing the structural strength of the air outlet grille 22. Optionally, there are a plurality of connecting ribs 222, and the plurality of connecting ribs 222 extend along the length direction of the air outlet channel 23 (such as Figure 6 spaced apart in the up and down directions shown).

[0062] like Figure 5 As shown, the air outlet frame assembly 2 also includes louvers 24, which are rotatably disposed within the air outlet passage 23. 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 delivery in two dimensions, realizing three-dimensional air delivery. The louvers 24 are located on the side of the air outlet grille 22 near the first end 231. This makes the structure of the air outlet frame assembly 2 more compact.

[0063] Furthermore, there are multiple louvers 24, which are spaced apart in a direction perpendicular to the rotation axis of the louvers 24, i.e., the rotation axis of the air outlet frame 21. The air outlet frame assembly 2 further includes a connecting rod, which is rotatably connected to the multiple louvers 24 to enable the multiple louvers 24 to rotate synchronously.

[0064] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0065] Furthermore, if Figure 5 As shown, the width direction of the louver 24 (as Figure 5 Both ends (in the left and right directions shown) are spaced apart from the inner wall of the air outlet channel 23, and along the air flow direction, the gap between the louver 24 and the inner wall of the air outlet channel 23 is the same. This facilitates the louver 24 to guide the air.

[0066] According to the air conditioner 100 of the embodiment of the present invention, Figure 1 As shown, it includes a shell 1 and the above-mentioned air outlet frame assembly 2.

[0067] Specifically, if Figure 1As shown, an air flow channel 113 is defined in the housing 1. The housing 1 has an air outlet 101 and an air inlet 102. The housing 1 defines an air flow channel 113, with both ends of the air flow channel 113 communicating with the air inlet 102 and the air outlet 101, respectively. A wind wheel 4 is provided in the air flow channel 113 and rotatably disposed in the air flow channel 113. A heat exchanger 5 is also provided in the housing 1 and is opposite to the air inlet 102. Under the action of the wind wheel 4, air flows in from the air inlet 102, and the air flows into the housing 1 and exchanges heat with the heat exchanger 5. The air flows after the heat exchange are discharged from the air outlet 101 into the room, thereby achieving indoor cooling or heating.

[0068] exist Figure 1 In the example shown, the housing 1 is formed into a columnar shape, and 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 arranged opposite to each other, and the air inlet 102 and the air outlet 101 are extended in the up-down direction, and the wind wheel 4 is extended in the up-down direction (such as Figure 6 The upper and lower directions shown extend.

[0069] like Figure 1 As shown, the air outlet frame 21 is rotatably provided at the air outlet 101. Thus, the air outlet frame 21 can be rotated so that the first end 231 is located upstream of the second end 232 or the second end 232 is located upstream of the first end 231 along the air flow direction. Figure 3 As shown, when the first end 231 is located upstream of the second end 232, since the cross-sectional area of ​​the second end 232 is smaller than the cross-sectional area of ​​the first end 231, it can achieve the effect of gathering wind, thereby achieving the purpose of increasing the air supply speed and air supply distance; Figure 4 As shown, when the second end 232 is located upstream of the first end 231, since the cross-sectional area of ​​the first end 231 is larger than the cross-sectional area of ​​the second end 232, it can diffuse the wind, thereby achieving the purpose of slowing down the wind speed and making the wind smooth.

[0070] According to the air conditioner 100 of an embodiment of the present invention, the air outlet frame 21 is rotatably provided at the air outlet 101, and the cross-sectional area of ​​the first end 231 of the ground air outlet channel 23 is made larger than the cross-sectional area of ​​the second end 232. By adjusting the positional relationship between the first end 231 and the second end 232 in the flow direction of the airflow, the purpose of increasing the air supply speed and the air supply distance or achieving the purpose of slowing down the wind speed and smoothing the air outlet can be achieved, thereby meeting the different needs of users.

[0071] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the air conditioner 100 further includes a switch door 3, which is movably mounted 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 within the switch door 3. The switch door 3 can block the air outlet 101, preventing dust and liquid from entering the interior of the housing 1, thereby preventing dust and dirt. At the same time, the switch door 3 shields the air outlet frame 21 structure and other structures within the housing 1, making the appearance of the air conditioner 100 more beautiful.

[0072] like Figure 1 and Figure 2 As shown, the opening and closing door 3 is 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 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.

[0073] Furthermore, a first motor for driving the switch door 3 to rotate can be provided in the shell 1, and a gear connected to the first motor can be provided in the shell 1. A rack that cooperates with the gear can 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, and then realizing the opening and closing of the air outlet 101.

[0074] 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 that cooperates with the guide groove, thereby limiting the movement trajectory of the switch door 3.

[0075] Furthermore, if Figure 1 and Figure 2 As shown, the door 3 has a first cavity 322 structure inside, which can reduce the weight of the door 3, improve the structural strength of the door 3, and further improve the thermal insulation effect of the door 3. Specifically, the 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.
