[0070] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may adjust them as needed to suit specific applications.

[0071] Secondly, it should be noted that in the description of the present invention, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0072] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0073] At present, vertical air conditioners, also known as cabinet air conditioners, are more suitable for the area covered by the wind than wall-mounted air conditioners. The human body is exposed to a large area of ​​wind, which increases the speed of change of the human body's surface temperature.

[0074] In the related art, a floor-standing air conditioner includes a housing and an air duct assembly mounted within the housing. The housing is provided with an air outlet and an air inlet. The air duct assembly includes a duct housing and vertical swing vanes. The duct housing is securely mounted to the housing and has an opening communicating with the air outlet. The vertical swing vanes are rotatably mounted within the opening and are shaped like a grille. The vertical swing vanes are used to adjust the airflow direction of the floor-standing air conditioner left and right. However, the airflow from these floor-standing air conditioners directly blows onto the user, reducing user comfort.

[0075] After careful analysis, the inventors of the present disclosure discovered that the main reason for the aforementioned problem is that the vertical swing blades are used to change the airflow direction of the vertical air conditioner in the left-right direction, allowing the air to blow to different areas, but the air always blows directly towards the user. In other words, the airflow direction of the vertical air conditioner is towards the user, and the air can directly contact the user. However, when the air blows directly towards the user or blows towards the user for a long time, the user may feel uncomfortable and even develop symptoms such as colds and fevers.

[0076] In light of this, the inventors of the present disclosure have provided a vertical swing blade that can change the direction of airflow, thereby preventing wind from blowing directly at the user and improving user comfort. This disclosure provides an air outlet notch on the vertical swing blade, with the centerline of the air outlet notch tilted upward. As the vertical swing blade delivers air, the inner wall of the air outlet notch acts to direct the airflow in an upward direction, thereby directing the air above the user and preventing it from blowing directly at the user, thereby improving the user experience.

[0077] The preferred technical solutions of the vertical swing blade, air duct assembly, indoor unit and air conditioner of the present invention are described below in conjunction with specific embodiments.

[0078] Figure 1 Schematic diagram of the structure of the vertical swing blade of this embodiment. Figure 2 Schematic diagram of the structure of the swing blade of this embodiment. Figure 3 Schematic diagram of the air outlet opening of this embodiment.

[0079] This embodiment provides a vertical swing leaf 100, such as Figure 1 As shown, the vertical swing blade 100 includes at least a plurality of swing blades 110 arranged side by side and at intervals. The number of the swing blades 110 can be a positive integer such as 2, 3, 4, 5, etc. For example, in this embodiment, the number of the swing blades 110 can be 3.

[0080] like Figure 2 As shown, each swing blade 110 includes a main body 111 and a plurality of blades 112. The main body 111 refers to the main body of the swing blade 110, which is used to support the plurality of blades 112 and is rotatably connected to the air duct housing 200 of the indoor unit. In addition, the main body 111 is also rotatably connected to the rotating motor. When the rotating part rotates about the rotation axis, the wind direction in the indoor unit in the left and right directions can be changed, so that the wind can be blown to different areas.

[0081] It can be understood that the main body 111 and the blade portion 112 can be an integrated structure. On the one hand, it can improve the connection strength between the main body 111 and the blade portion 112, which helps to increase the service life of the pendulum blade 110. On the other hand, it can reduce the manufacturing difficulty of the main body 111 and the blade portion 112, and can be formed in one step by injection molding or other methods.

[0082] like Figure 2 As shown, the plurality of blades 112 are arranged side by side and spaced apart along the length direction of the main body 111. Figure 2 The Z direction) can be parallel to the vertical direction. In addition, multiple blade portions 112 are arranged side by side. In other words, multiple blade portions 112 are located on the same side of the main body 111. The connection end of each blade portion 112 is tightly connected to the main body 111, and two adjacent blade portions 112 and the main body 111 jointly define an air outlet gap 113. Since there are multiple blade portions 112, each swing blade 110 has multiple air outlet gaps 113, and the multiple air outlet gaps 113 are spaced apart along the length direction of the main body 111. Figure 3 As shown, when the indoor unit is delivering air, the air outlet gap 113 is used to direct part of the air in the air supply direction (for example Figure 3 The air is sent out in the Y direction so that the wind can go to the predetermined area. Figure 3 In this way, the wind can be located above the user's head to avoid the wind coming into contact with the user.

[0083] It should be noted that the inner wall structure of the air outlet notch 113 can be used to direct the wind in an obliquely upward direction. Since the air outlet notch 113 is defined by the two adjacent blade portions 112 and the sidewalls of the main body 111, the wind can be directed in the direction of the air supply by adjusting the structure of the two adjacent blade portions 112. For example, in this embodiment, by arranging the blade portions 112 upward so that the blade portions 112 intersect with the horizontal plane, the air outlet notch 113 has two opposing inclined surfaces, which can change the direction of the wind.

[0084] It can be understood that the pendulum 110 has a left and right swing function to adjust the wind direction in the left and right directions of the indoor unit. When the pendulum 110 rotates to the left, the wind can be sent to the left area of ​​the indoor unit. At this time, the wind will also enter the left area of ​​the indoor unit along the inclined upward air supply direction.

[0085] Since the hot air floats upward, the cold air sent out by the swing blades 110 along the upward inclined air supply direction can quickly come into contact with the hot air, which helps to increase the cooling speed of the user's environment.

[0086] In a possible embodiment, the angle between the center line of each blade portion 112 and the horizontal direction is 40° to 60°. This arrangement can send wind above the user's head to avoid blowing directly on the user.

[0087] When the angle between the center line of the blade portion 112 and the horizontal direction is between 40° and 60°, on the one hand, it can prevent the wind from blowing directly on the user, and on the other hand, it can balance the air supply distance and air volume to ensure the use effect.

[0088] The angle between the center line of the blade portion 112 and the horizontal direction can be determined according to usage requirements and is not specifically limited here. For example, in this embodiment, the angle between the center line of the blade portion 112 and the horizontal direction can be 55°, which helps to increase the air supply distance while increasing the air volume.

[0089] Figure 4 It is a partial enlarged view of the blade portion of this embodiment.

[0090] In one possible implementation, Figure 4As shown, the longitudinal section of each blade portion 112 includes a first plate-shaped segment 1121 and a second plate-shaped segment 1122. The longitudinal section of the blade portion 112 is parallel to the length direction of the main body portion 111 and perpendicular to the horizontal direction. The first end of the first plate-shaped segment 1121 and the first end of the second plate-shaped segment 1122 are both fastened to the main body portion 111. The second end of the first plate-shaped segment 1121 is fastened to the second end of the second plate-shaped segment 1122. The inner surface of the first plate-shaped segment 1121 and the inner surface of the second plate-shaped segment 1122 jointly define a step surface 1123. By providing the step surface 1123 on the blade portion 112, it helps to increase the amount of air passing through the air outlet gap 113 and can guide the wind into the air outlet gap 113, and then send it out in the air supply direction.

[0091] It should be noted that the inner surface of the first plate-shaped segment 1121 and the inner surface of the second plate-shaped segment 1122 are both surfaces located within the air outlet slot 113. In addition, each air outlet slot 113 may have a stepped surface 1123, which may be located on the lower blade portion 112 of the two blade portions 112 forming the air outlet slot 113 to ensure that the wind moves in an obliquely upward direction.

[0092] The angle between the inner surface of the first plate-shaped segment 1121 and the inner surface of the second plate-shaped segment 1122 can be a right angle or an obtuse angle, without specific limitation. For example, in some examples, the angle between the inner surface of the first plate-shaped segment 1121 and the inner surface of the second plate-shaped segment 1122 can be 120°, 135°, 150°, or the like.

[0093] In a possible embodiment, the distance between two adjacent blade portions 112 along the length direction of the main body 111 may be 12 mm to 15 mm. Such an arrangement helps to increase the amount of air moving along the air supply direction.

[0094] It can be understood that the height of each air outlet gap 113 in the length direction of the main body 111 is 12mm to 15mm, and the specific value is not limited here. For example, the height of each air outlet gap 113 in the length direction of the main body 111 can be 12mm, 13mm, 14mm and other values.

[0095] In a possible embodiment, along a length direction perpendicular to the main body 111 , the depth of each air outlet gap 113 may be 15 mm to 18 mm. This configuration helps to increase the air volume passing through the air outlet gap 113 .

[0096] The depth of the air outlet notch 113 can be determined according to the use requirements and is not specifically limited here. For example, the depth of the air outlet notch 113 can be 16 mm, 17 mm, or 17.5 mm.

[0097] Figure 5 1 is an exploded view of the air duct assembly of this embodiment.

[0098] In a possible embodiment, since the vertical swing blade 100 has multiple swing blades 110, the rotation of the swing blade 110 is achieved by a rotary motor. In order to reduce the number of rotary motors, as shown in FIG. Figure 5 As shown, the vertical swing blade 100 further includes a connecting rod 120 , which is used to enable the multiple swing blades 110 to rotate synchronously.

[0099] like Figure 2 As shown, the main body 111 includes a first connecting portion 1111, an intermediate portion 1112, and a second connecting portion 1113. The intermediate portion 1112 has two ends that are respectively fastened to the connecting ends of the first connecting portion 1111 and the connecting ends of the second connecting portion 1113, and is used to fasten the connecting ends of the plurality of blade portions 112. The first connecting portion 1111 and the second connecting portion 1113 are each configured to be rotatably connected to the air duct housing 200, and at least one of the first connecting portion 1111 and the second connecting portion 1113 is configured to be movably connected to the connecting rod 120. With this structure, the main body 111 can be connected to the connecting rod 120 and can be rotatably connected to the air duct housing 200.

[0100] It should be noted that at least one of the first connection part 1111 and the second connection part 1113 is used for transmission connection with the output shaft of the rotating motor. In other words, the number of rotating motors is at least one. In addition, each pendulum blade 110 can be matched with one rotating motor, or each pendulum blade 110 can be matched with two rotating motors. There is no specific restriction here.

[0101] The first connection portion 1111 , the middle portion 1112 and the second connection portion 1113 may be an integral structure, which helps to improve the connection strength of the first connection portion 1111 , the middle portion 1112 and the second connection portion 1113 and can improve the manufacturing efficiency of the main body 111 .

[0102] It is understandable that when there is only one connecting rod 120 , the connecting rod 120 can be movably connected to the first connecting portions 1111 of all the pendulum blades 110 , or the connecting rod 120 can be movably connected to the second connecting portions 1113 of all the pendulum blades 110 .

[0103] When there are two connecting rods 120, the first connecting parts 1111 of all the pendulum blades 110 are movably connected to one of the connecting rods 120, and the second connecting parts 1113 of all the pendulum blades 110 are movably connected to the other connecting rod 120. This arrangement helps to improve the stability of the movement of the pendulum blades 110 and improve the consistency of the movement of the pendulum blades 110. For example, in some examples, such as Figure 5As shown, the invention further comprises: a first connecting rod 120a and a second connecting rod 120b. The first connecting parts 1111 of the plurality of pendulum blades 110 are movably connected to the first connecting rod 120a. The second connecting parts 1113 of the plurality of pendulum blades 110 are movably connected to the second connecting rod 120b.

[0104] Figure 6 It is a perspective view of the connecting rod of this embodiment.

[0105] In one possible implementation, Figure 6 As shown, the connecting rod 120 includes a rod-shaped main body 121 and a plurality of movable connecting portions 122. The plurality of movable connecting portions 122 are arranged side by side and spaced apart along the length of the rod-shaped main body 121. The plurality of movable connecting portions 122 are respectively configured to be movably connected to the first connecting portions 1111 or the second connecting portions 1113 of the plurality of swing blades 110.

[0106] The movable connection portion 122 and the rod-shaped body portion 121 may be an integral structure, which helps to improve the manufacturing efficiency of the connecting rod 120 .

[0107] The specific structure of the movable connection part 122 can be determined according to the specific structure of the first connection part 1111 or the second connection part 1113. For example, in some examples, the movable connection part 122 can be a ring structure, and the first connection part 1111 and / or the second connection part 1113 has a rotating part inserted into the ring structure. Or, in some examples, such as Figure 6 As shown, the movable connection part 122 includes two oppositely arranged first clamping parts 1221, and the two first clamping parts 1221 jointly define a clamping gap, which is used to connect with the first connection part 1111 and / or the second connection part 1113 having a rotating shaft part inserted into the clamping gap.

[0108] Figure 7 It is a partial three-dimensional view of the first connecting portion of this embodiment.

[0109] In one possible implementation, Figure 7 As shown, the first connecting portion 1111 includes a first plate portion 11111, a first rod portion 11112, and a first rotating shaft portion 11113. The first rod portion 11112 is used for rotational connection with the air duct housing 200. In addition, the first rod portion 11112 can also be used for transmission connection with the output shaft of the rotating motor.

[0110] The opposite ends of the first plate-shaped portion 11111 are respectively fastened to the connecting end of the first rod-shaped portion 11112 and the first end of the intermediate portion 1112. A first notch is provided on the first plate-shaped portion 11111. The first notch can be located on the same side of the first plate-shaped portion 11111 as the blade portion 112 or on a different side, without specific limitation. For example, in this embodiment, the first notch and the blade portion 112 are located on different sides of the first plate-shaped portion 11111. The first rotating shaft portion 11113 is disposed within the first notch and is used to be rotatably connected to the connecting rod 120, so that the multiple swing blades 110 rotate in unison.

[0111] It can be understood that the first rotation shaft portion 11113 is parallel to the rotation axis of the pendulum blade 110. In addition, the first rotation shaft portion 11113 can be used to cooperate with the clamping notch of the connecting rod 120 to enable the multiple pendulum blades 110 to rotate synchronously.

[0112] The shape of the first plate-shaped portion 11111 may be a polygon. For example, the first plate-shaped portion 11111 may be a polygon such as a quadrilateral or a pentagon.

[0113] In some examples, the end surface of the free end of the first rod-shaped portion 11112 may be provided with a polygonal groove, which is used for inserting the motor shaft of the rotating motor and engaging with the motor shaft, so that the rotating motor can drive the swing blade 110 to rotate.

[0114] Figure 8 It is a partial three-dimensional view of the second connecting portion of this embodiment.

[0115] In one possible implementation, Figure 8 As shown, the second connecting portion 1113 includes a second plate portion 11131, a second rod portion 11132, and a second rotating shaft portion 11133. The second rod portion 11132 is used for rotational connection with the air duct housing 200. In addition, the second rod portion 11132 can also be used for transmission connection with the output shaft of the rotating motor.

[0116] The opposing ends of the second plate-shaped portion 11131 are respectively fastened to the connecting end of the second rod-shaped portion 11132 and the second end of the intermediate portion 1112. A second notch is provided in the second plate-shaped portion 11131. The second notch can be located on the same side of the second plate-shaped portion 11131 as the blade portion 112, or on a different side. This is not particularly limited. For example, in this embodiment, the second notch and the blade portion 112 are located on different sides of the second plate-shaped portion 11131. The second rotating shaft portion 11133 is disposed within the second notch and is configured to be rotatably connected to the connecting rod 120, thereby allowing the multiple swing blades 110 to rotate synchronously.

[0117] It can be understood that the second rotation shaft portion 11133 is parallel to the rotation axis of the pendulum blade 110. In addition, the second rotation shaft portion 11133 can be used to cooperate with the clamping notch of the connecting rod 120 to enable the multiple pendulum blades 110 to rotate synchronously.

[0118] The shape of the second plate-shaped portion 11131 can be a polygon. For example, the second plate-shaped portion 11131 can be a polygon such as a quadrilateral or a pentagon.

[0119] In some examples, the end face of the free end of the second rod-shaped portion 11132 may also be provided with a polygonal groove, which is used for inserting the motor shaft of the rotating motor and engaging with the motor shaft, so that the rotating motor can drive the swing blade 110 to rotate.

[0121] In one possible implementation, Figure 9 As shown, the middle portion 1112 includes a third plate-shaped portion 11121 and a plurality of third rotating shaft portions 11122. The opposite ends of the third plate-shaped portion 11121 are respectively fastened to the first connecting portion 1111 and the second connecting portion 1113. The third plate-shaped portion 11121 is provided with a plurality of third notches spaced apart along the length direction of the main body portion 111. Each third notch is provided with a third rotating shaft portion 11122. The third rotating shaft portion 11122 is used to be rotatably connected to the supporting beam 214 of the air duct housing 200. The connecting ends of the plurality of blade portions 112 are fastened to the third plate-shaped portion 11121. By adopting the middle portion 1112 having the third rotating shaft portion 11122, the number of support points between the swing blade 110 and the air duct housing 200 is increased, thereby improving the stability of the movement of the swing blade 110.

[0122] The number of the third rotating shaft portions 11122 can be 2, 3, 4, etc., and is not specifically limited here. It should be noted that the number of the third rotating shaft portion 11122 can also be one, in which case the third plate-shaped portion 11121 is provided with a third notch, which can be located in the middle of the third plate-shaped portion 11121.

[0123] The third notch and the blade portion 112 may be located on the same side or different sides of the third plate-shaped portion 11121 , without specific limitation.

[0124] To reduce the volume of the middle portion 1112, the third plate-shaped portion 11121 may further include a plurality of fourth notches spaced apart along the length of the main portion 111, with a third notch positioned between two adjacent fourth notches. Multiple blades 112 are positioned within each fourth notch, and the free end surfaces of the blades 112 may be coplanar with the end surface of the third plate-shaped portion 11121.

[0127] It is understandable that the shape of the opening 230 is a polygon, for example, the opening 230 is a quadrilateral, a pentagon, etc., which is not specifically limited here.

[0128] In one possible implementation, Figure 10 As shown, the air duct housing 200 includes a front volute tongue 210 and an air duct 220. The front volute tongue 210 and the air duct 220 together define an opening 230. The vertical swing blade 100 can be installed in the opening 230 and rotatably connected to the top and bottom ends of the front volute tongue 210 respectively.

[0129] In some examples, such as Figure 5 As shown, the front volute tongue 210 includes a top cover 211, a bottom cover 213, a connecting plate 212, and at least one supporting beam 214. The connecting plate 212 has opposite ends fastened to the top cover 211 and the bottom cover 213, respectively. The first end of the at least one supporting beam 214 is fastened to the connecting plate 212 and positioned between the top cover 211 and the bottom cover 213. If there are multiple supporting beams 214, they are spaced apart along the length of the connecting plate 212.

[0130] The top cover 211 is provided with at least two first through holes, and the first through holes are used for inserting the first connecting portion 1111 of the swing blade 110 , so that the air duct housing 200 is rotatably connected to the swing blade 110 .

[0131] The bottom cover 213 is provided with at least two second through holes, and the second through holes are used for inserting the second connecting portion 1113 of the swing blade 110 , so that the air duct housing 200 is rotatably connected to the swing blade 110 .

[0132] It can be understood that the number of the first through holes is equal to the number of the second through holes.

[0133] Figure 11 It is a partial enlarged view of the supporting beam of this embodiment.

[0134] In some examples, such as Figure 11 As shown, the support beam 214 includes a support plate portion 2141 and a plurality of mating portions 2142 , which are spaced apart along the length of the support plate portion 2141 . Each mating portion 2142 is configured to mate with the third rotation axis portion 11122 of the swing blade 110 .

[0135] In some examples, such as Figure 11 As shown, the matching portion 2142 includes two second clamping portions 21421 arranged opposite to each other, and the two second clamping portions 21421 jointly define a matching gap.
