[0040] Figure 1 is a schematic structural diagram of a vertical air conditioner indoor unit according to an embodiment of the utility model; Figure 2 is a schematic structural diagram of a blade swing device according to an embodiment of the utility model; Figure 3 yes Figure 2 A schematic partial enlarged view of the position shown. Figures 1 to 3As shown, the utility model provides a blade swing device 20 of a vertical air conditioner indoor unit 100. The vertical air conditioner indoor unit 100 generally includes a housing 10 extending in a vertical direction and a blade swing device 20. The swing blade device 20 includes a shell 21 and a swing blade assembly 22. The shell 21 extends along the height direction of the outer shell 10 of the vertical air conditioner indoor unit 100 and is connected to the outer shell 10. The shell 21 defines an installation space 211 and has a plurality of installation holes 212 and a plurality of limiting structures 213 arranged at intervals along its extension direction. Each limiting structure 213 is located at a mounting hole 212. The limiting structure 213 has a limiting portion 214 protruding from the shell 21 toward one side of the mounting space 211. At least part of the limiting portion 214 is located below the mounting hole 212. The swing blade assembly 22 is installed at the mounting space 211 and has a plurality of swing blades 221 arranged at intervals along the extension direction of the shell 21. Each swing blade 221 is installed at a mounting hole 212 and is rotatably connected to the mounting hole 212. Specifically, the limiting portion 214 located below the mounting hole 212 limits the rotation axis of the swing blade 221 within the limiting portion 214, so that the lubricating oil overflowing during the rotation of the swing blade 221 is blocked, thereby preventing the lubricating oil from overflowing and affecting the appearance of the vertical air conditioner indoor unit 100. Here, each limiting portion 214 is arranged corresponding to one mounting hole 212.

[0041] In this embodiment, each mounting hole 212 is provided with a stopper 214 protruding toward one side of the mounting space 211, and at least a portion of each stopper 214 is distributed below the mounting hole 212. The stopper 214 can limit the rotation axis of the swing blade 221 within the stopper 214, so that the lubricating oil overflowing during the rotation of the swing blade 221 is blocked, thereby preventing the lubricating oil from overflowing and affecting the appearance of the vertical air conditioner indoor unit 100. Here, the stopper 214 can be arranged around the circumference of the mounting hole 212, or can be partially arranged below the connection between the mounting hole 212 and the swing blade 221.

[0042] In this embodiment, part of the limiting portion 214 is arranged below the corresponding mounting hole 212. At this time, the limiting portion 214 can block the rotating shaft at the bottom of the swing blade 221 corresponding to the mounting hole 212, so that when the lubricating oil overflows toward the rotating shaft of the swing blade 221 and the side of the mounting hole 212 facing the mounting space 211, the limiting portion 214 can block the overflowing lubricating oil, which can effectively prevent the lubricating oil from overflowing from one side of the mounting space 211 or even dripping out, thereby preventing the lubricating oil from overflowing and affecting the appearance of the air conditioner or the lubricating oil from dripping out and causing pollution to the environment. Similarly, when the limiting portion 214 is arranged around the circumference of the corresponding mounting hole 212, the rotating shaft at the bottom of the swing blade 221 corresponding to the mounting hole 212 is completely blocked, thereby preventing the lubricating oil from overflowing to the outside of the swing blade 221 and affecting the appearance of the vertical air conditioner indoor unit 100 or the lubricating oil from dripping out and causing pollution to the environment.

[0043] In this embodiment, the limiting portion 214 has an opening toward the rear side of the vertical air conditioner indoor unit 100, and the mounting hole 212 is located at the inner side of the corresponding limiting portion 214. Specifically, the mounting hole 212 is located at a side away from the opening of the limiting portion 214. In other words, since the mounting hole 212 is located at the inner side of the corresponding limiting portion 214, the lubricating oil flowing in from the mounting hole 212 can be shielded by the limiting portion 214 when dripping, thereby preventing the lubricating oil from overflowing to the outside of the swing blade 221 and affecting the appearance of the vertical air conditioner indoor unit 100.

[0044] In this embodiment, the protrusion thickness of the limiting portion 214 gradually decreases along the direction from its root to the head. Specifically, the protrusion thickness of the limiting portion 214 near the mounting hole 212 is greater than the protrusion thickness near the opening, and the limiting portion 214 near the mounting hole can be used to shield the excess lubricating oil overflowing from the connection between the swing blade 221 and the mounting hole 212. In other words, since the lubricating oil overflows from the connection between the mounting hole 212 and the swing blade 221, in order to better shield the lubricating oil overflowing from the connection between the mounting hole 212 and the swing blade 221, the protrusion thickness of the limiting portion 214 near the mounting hole 212 is set to be greater than the protrusion thickness of the limiting portion 214 near the opening. Since the amount of lubricating oil overflowing near the opening is less than that near the mounting hole 212, the protrusion thickness of the limiting portion 214 arranged near the opening is smaller than that of the limiting portion 214 near the mounting hole 212, so that the limiting portion 214 can prevent the lubricating oil from overflowing and affecting the appearance of the vertical air conditioner indoor unit 100 or the lubricating oil from dripping and polluting the environment. At the same time, the limiting portions 214 with different protrusion thicknesses can reduce the weight of the shell 21 compared to the limiting portions 214 with the same protrusion thickness, thereby reducing the overall mass of the vertical air conditioner indoor unit 100, making the transportation of the vertical air conditioner indoor unit 100 easier.

[0045] In this embodiment, the vertical air conditioner indoor unit 100 has an air outlet 11 facing the front of the housing 10 , that is, the protruding thickness of the limiting portion 214 gradually decreases from the front side to the rear side of the vertical air conditioner indoor unit 100 .

[0046] In this embodiment, the stopper 214 extends to the edge of the housing 21. Specifically, since the stopper 214 in this embodiment has an opening toward the front side of the vertical air conditioner indoor unit 100, and the protrusion thickness of the stopper 214 gradually decreases along the direction from the opening of the stopper 214 toward the mounting hole 212, when the lubricating oil overflows to the inner side of the stopper 214 on the peripheral side of the mounting hole 212 and the amount of the overflowed lubricating oil is large, the stopper 214 extending to the edge of the housing 21 can effectively prevent the lubricating oil from overflowing from the stopper 214, thereby avoiding affecting the appearance of the vertical air conditioner indoor unit 100.

[0047] In this embodiment, the limiting portion 214 is circular or elliptical, and the mounting hole 212 is located on the inner side of the corresponding limiting portion 214. Specifically, the limiting portion 214 can be circular or elliptical, and the mounting hole 212 is located on the inner side of the corresponding circular or elliptical limiting portion 214. The circular or elliptical limiting portion 214 can block the rotating shaft of the swing blade 221 corresponding to the mounting hole 212, so that when the lubricating oil overflows toward the rotating shaft of the swing blade 221 and the mounting hole 212 toward an outer side of the mounting space 211, the circular or elliptical limiting portion 214 can block the overflowing lubricating oil, thereby effectively preventing the lubricating oil from overflowing or even dripping, avoiding affecting the appearance of the air conditioner or causing pollution to the environment. In other embodiments, the limiting portion 214 can also be a square or triangular structure.

Figures 4 to 7 As shown, in this embodiment, the limiting structure 213 also includes a limiting groove 215 arranged at the back of the limiting portion 214, and the mounting hole 212 is located at the inner side of the corresponding limiting groove 215. Specifically, the limiting groove 215 is located at the back of the limiting portion 214, and the area and shape of the limiting groove 215 are consistent with the area and shape of the limiting portion 214, so that after the lubricating oil drips from the limiting groove 215 into the bottom of the swing blade 221 rotating shaft at the bottom of the mounting hole 212, the excess lubricating oil is stored in the limiting groove 215, so as to prevent the lubricating oil from overflowing to the bottom of the housing 21 and causing unnecessary pollution to the housing 21.

[0049] In this embodiment, the limiting groove 215 is also "U"-shaped and has an opening toward the rear of the vertical air conditioner indoor unit 100, and the groove depth of the limiting groove 215 gradually decreases from the front side to the rear side of the vertical air conditioner indoor unit 100.

[0050] In other embodiments, the limiting groove 215 may also be a circular or elliptical structure, and the mounting hole 212 is located in the corresponding circular or elliptical limiting groove 215, which can store excess lubricating oil and prevent the lubricating oil from overflowing to the bottom of the shell 21.

[0051] Figure 8 is a schematic rear view of the installation of a swing blade in a swing blade device according to an embodiment of the utility model; Fig. 9 yes Figure 8 A schematic partial enlarged view of D is shown. Figures 8 to 9As shown, in this embodiment, the swing blade device 20 also includes a plurality of first connecting rods 23 and a second connecting rod 24, each of which corresponds to a swing blade 221 and is connected to the swing blade 221, at least part of the first connecting rod 23 is located in the corresponding limiting groove 215, and the second connecting rod 24 extends along the extension direction of the housing 21 and is connected to the plurality of first connecting rods 23, so as to drive all the swing blades 221 to swing when moving along the extension direction of the housing 21 under force. Specifically, each swing blade 221 is connected to the second connecting rod 24 through a first connecting rod 23, so that when the second connecting rod 24 is subjected to force, all the swing blades 221 are driven to swing, thereby delivering air to the air outlet 11 of the indoor unit 100 of the vertical air conditioner. Here, the second connecting rod 24 is in the shape of a vertical long strip, and has a plurality of long first positioning holes 241, and each first positioning hole 241 is arranged corresponding to a first connecting rod 23.

[0052] In this embodiment, a motor is provided at each end of the second connecting rod 24 for driving the second connecting rod 24 to move up and down, and the swing blade 221 is connected to the first connecting rod 23, and the first connecting rod 23 is connected to the second connecting rod 24. When the second connecting rod 24 moves, it can drive the first connecting rod 23 to rotate, and drive the swing blade 221 to rotate through the first connecting rod 23, thereby using the swing blade 221 to guide the airflow of the air outlet 11 of the indoor unit 100 of the vertical air conditioner to change the flow direction of the airflow.

[0053] In this embodiment, the first connecting rod 23 has a rotating shaft connected to the first positioning hole 241 on the second connecting rod 24, and a first mounting component 232 is provided on the rotating shaft. The swing blade 221 has a rotating shaft connected to the mounting hole 212, and a second mounting component 222 is provided on the rotating shaft. The first mounting component 232 and the second mounting component 222 are respectively composed of two hooks arranged opposite to each other. The end of the first connecting rod 23 away from the first mounting component 232 is provided with a second positioning hole 231, each first positioning hole 241 is arranged correspondingly with a first mounting component 232, and each second positioning hole 231 is arranged correspondingly with a second mounting component. Specifically, the first positioning hole 241 cooperates with the first mounting component 232 to connect the first connecting rod 23 with the second connecting rod 24, and the second positioning hole 231 cooperates with the second mounting component to connect the swing blade 221 with the first connecting rod 23. In other words, the swing blade 221 is connected to the first connecting rod 23, thereby connecting the housing 21 with the second connecting rod 24.

[0054] In this embodiment, the two hooks constituting the first mounting component 232 are arranged in opposite directions, so that the first mounting component 232 on the first connecting rod 23 matches the first positioning hole 241 on the second connecting rod 24, and the first mounting component 232 is slightly deformed at this time, so that the first mounting component 232 is installed in the first positioning hole 241, and the deformation is restored after the installation is completed. Similarly, the two hooks constituting the second mounting component 222 are arranged in opposite directions, so that the second mounting component 222 on the swing blade 221 matches the second positioning hole 231 on the first connecting rod 23, and the second mounting component 222 is slightly deformed at this time, so that the second mounting component 222 is installed in the second positioning hole 231, and the deformation is restored after the installation is completed. That is to say, the first mounting component 232 and the second mounting component 222 are both two hooks arranged back to back, so that the connection between the first connecting rod 23 and the second connecting rod 24 and the connection between the swing blade 221 and the first connecting rod 23 do not require multiple connecting parts or cumbersome connection relationships, thereby simplifying the assembly of the swing blade device 20 and further simplifying the assembly process of the vertical air conditioner indoor unit 100.

[0055] In this embodiment, the multiple hooks constituting the first mounting member 232 and the second mounting member 222 are provided with grooves at one end away from the vertical air conditioner indoor unit 100, and the grooves at the ends of the two hooks on the first mounting member 232 match the first positioning hole 241, so that the second connecting rod 24 is connected to the first connecting rod 23. Specifically, the two hooks of the first mounting member 232 are first brought close to each other and deformed, so that the first mounting member 232 is inserted into the first positioning hole 241, and then the hooks are restored to their deformation, so that the first mounting member 232 is connected to the first positioning hole 241, and then the second connecting rod 24 is connected to the first connecting rod 23.

[0056] In this embodiment, the grooves at the ends of the two hooks on the second mounting member 222 match the second positioning hole 231, so that the first connecting rod 23 is connected to the swing blade 221. Specifically, the two hooks of the second mounting member 222 are first brought close to each other and deformed, so that the second mounting member 222 is sequentially inserted into the mounting hole 212 and the second positioning hole 231, and then the hooks are deformed again, so that the second mounting member 222 is connected to the second positioning hole 231, and then the second connecting rod 24 and the first connecting rod 23 are connected.

[0057] In this embodiment, the two hooks on the second mounting part 222 on the swing blade 221 are just engaged with the second positioning hole 231 on the first connecting rod 23, so that the swing blade 221 is stably fixed on the first connecting rod 23, the position of the swing blade 221 does not shift, and the air outlet direction is stable. The first positioning hole 241 on the second connecting rod 24 is just engaged with the two hooks on the first mounting part 232 of the first connecting rod 23 to connect the second connecting rod 24 and the first connecting rod 23. Since the second connecting rod 24 can be driven up and down by the motor, the first mounting part 232 on the first connecting rod 23 can move along the length direction of the second positioning hole 231, and the swing blade 221 is connected to the first connecting rod 23, so that the swing blade 221 can be stably displaced as the second connecting rod 24 moves up and down.

[0058] In this embodiment, the housing 21 includes at least one mounting hole group, and each mounting hole group includes at least one mounting hole 212. Specifically, there are four mounting hole groups in this embodiment, and the number of mounting holes 212 in each mounting hole group is five. The multiple mounting hole groups are evenly spaced along the height direction of the housing 21, and the mounting holes 212 in each mounting hole group are evenly spaced along the height direction of the housing 21. In this embodiment, the number of mounting hole groups can be designed according to the length of the second connecting rod 24, and the number of each mounting hole 212 in each mounting hole group can be designed according to the number of swing blades 221 in the swing blade assembly 22.

[0059] In this embodiment, the second connecting rod 24 is divided into a plurality of first positioning holes 241, and each first positioning hole 241 corresponds to a swing blade 221, so that the plurality of swing blades 221 can be evenly spaced on the second connecting rod 24, and when the vertical air conditioner indoor unit 100 is exhausting air, the exhaust airflow can be evenly distributed, thereby improving the user experience.

[0060] In this embodiment, the top of the swing blade 221 and the second mounting member 222 at the bottom of the swing blade 221 are on the same straight line, and the straight line is perpendicular to the first connecting rod 23 and the second connecting rod 24. The second mounting member 222 at the bottom of the swing blade 221 is connected to the first connecting rod 23, and the first connecting rod 23 is connected to the second connecting rod 24, so that the swing blade 221 is located away from the first connecting rod 23 and the second connecting rod 24 to prevent the swing blade 221 from interfering with the first connecting rod 23 and the second connecting rod 24 during the rotation process, thereby avoiding damage to the vertical air conditioner indoor unit 100.

[0061] In this embodiment, the vertical air conditioner indoor unit 100 further includes a fan and a heat exchanger disposed inside the housing 10 of the vertical air conditioner indoor unit 100, and an air inlet and an air outlet 11 disposed at the rear side and the front side of the housing 10 of the vertical air conditioner indoor unit 100, respectively. Specifically, the airflow passes through the air inlet, the heat exchanger, the fan, the swing blade device 20 in sequence from entering the air inlet to blowing out from the air outlet 11, and finally blows out from the air outlet 11. That is, when the vertical air conditioner indoor unit 100 is running, under the action of the fan, the air in the conditioned room is sucked into the housing 10 of the vertical air conditioner indoor unit 100 from the air conditioning air inlet of the vertical air conditioner indoor unit 100, and heat exchanges with the heat exchanger located in the housing 10 to generate cold air or hot air, and then the cold air or hot air is blown out from the air outlet 11 of the vertical air conditioner indoor unit 100. According to the user's needs, the multiple swing blades 221 in the swing blade assembly 22 rotate simultaneously under the drive of the first connecting rod 23 and the second connecting rod 24 to form air outlet channels at different angles, thereby adjusting the air outlet direction of the air outlet 12 of the vertical air conditioner indoor unit 100 in the vertical direction.

[0062] In this embodiment, a rotatable air guide plate 12 is provided at the air outlet 11 for adjusting the direction of the airflow at the air outlet 11. Specifically, the air guide plate 12 can be set to a rotation angle according to user needs, so as to control the direction of the airflow blowing out from the air outlet 11, and the second connecting rod 24 can drive the first connecting rod 23 to move when the force is applied, thereby driving the swing blade 221 to swing, and the swing angle of the swing blade 221 can also adjust the direction of the airflow in the air duct, so that the airflow is finally blown out in the direction required by the user.

Figure 10 to Figure 11 As shown, in this embodiment, the swing blade 221 has a wavy curved surface structure, and the second positioning hole 231 is square. Specifically, the wavy curved surface structure on the surface of the swing blade 221 is composed of a plurality of regular hexagons, and a plurality of regular hexagons of the same area form an undulating curved surface structure of the swing blade 221, so that the airflow passing through the swing blade 221 is guided by the undulating shape of the surface of the swing blade 221, so that the airflow is blown out from different directions, the airflow outlet range is expanded, and the airflow diversion is realized, so that the airflow blown out at the air outlet 11 of the indoor unit 100 of the vertical air conditioner is closer to the effect of natural wind.

[0064] The utility model provides a vertical air conditioner indoor unit 100, comprising any one of the above-mentioned swing blade devices 20. The swing blade device 20 is not described in detail here.

[0065] The swing blade device 20 of this embodiment includes a shell 21 and a swing blade assembly 22. The shell 21 defines an installation space 211 and has a plurality of installation holes 212 and a plurality of limiting structures 213 arranged at intervals along its extension direction. The limiting structure 213 has a limiting portion 214 protruding from the shell 21 toward the side of the installation space 211, and at least a portion of the limiting portion 214 is located below the installation hole 212. The swing blade assembly 22 has a plurality of swing blades 221 arranged at intervals along the extension direction of the shell 21. Each swing blade 221 is rotatably connected to the corresponding installation hole 212, so that the limiting portion 214 limits the rotating shaft of the swing blade 221 within the limiting portion 214, so that the lubricating oil overflowing from the outside of the swing blade 221 is blocked, thereby preventing the lubricating oil from overflowing and affecting the appearance of the vertical air conditioner indoor unit 100. In addition, the limiting structure 213 of this embodiment also includes a back limiting groove 215 arranged on the limiting portion 214, and the mounting hole 212 is located on the inner side of the corresponding limiting groove 215. When lubricating oil is added to the back limiting groove 215, dripping of lubricating oil can be prevented. Even if the lubricating oil flows from the mounting hole 212 to the front side of the swing blade assembly 22 during the rotation of the swing blade 22, the lubricating oil will be limited by the limiting portion 214 to prevent dripping, which is equivalent to preventing the lubricating oil from dripping on both sides of the swing blade assembly 22.
