[0039] Reference below Figure 1-Figure 11 According to the air conditioner 100 of the embodiment of the utility model, the swing blade 21 of the swing blade assembly 2 is located in the air duct 11, which has a guiding effect on the air outlet, and the crank 22 and the driving structure are hidden in the surface frame 1, thereby avoiding the generation of condensation at the installation position of the swing blade 21, effectively reducing the phenomenon of dripping after water accumulation in the air conditioner, improving the service life of the air conditioner 100, and avoiding the connection position of the swing blade 21 blocking the airflow and thus affecting the air volume, thereby reducing wind noise.

[0040] like Figure 1-Figure 11 As shown, an air conditioner 100 according to an embodiment of the present utility model includes: a face frame 1 and a swing blade assembly 2.

[0041] The face frame 1 is formed with an air duct 11, and an installation space 12 separated from the air duct 11 is formed inside the face frame 1. That is to say, the installation space 12 and the air duct 11 are separated by the face frame 1, that is, one side of the face frame 1 is the air duct 11 for air outlet, and the other side is the installation space 12 for installing other structural components, which separates the structural components from the air duct 11 to hide the structural components.

[0042] The swing blade assembly 2 includes a swing blade 21, a crank 22 and a driving structure. The swing blade 21 is rotatably installed in the air duct 11, the driving structure is installed in the installation space 12, and the crank 22 is passed through the face frame 1 to dynamically connect the swing blade 21 to the driving structure.

[0043] Specifically, the swing blade assembly 2 is installed near the air outlet of the face frame 1, and the swing blade assembly 2 includes a swing blade 21, a crank 22 and a driving structure. The swing blade 21 is connected to one end of the crank 22 and the other end of the crank 22 is connected to the driving structure, wherein the driving structure includes a driving motor, and the driving motor drives the crank 22 and the swing blade 21 to rotate, thereby changing the air outlet direction to meet the air outlet requirements of the air conditioner 100. Figure 3 As shown, the swing blade 21 and one end of the crank 22 are rotatably installed in the air duct 11, and the crank 22 passes through the face frame 1, that is, the crank 22 is arranged in the air duct 11 and the installation space 12, and one end of the crank 22 in the installation space 12 is connected to the driving structure power, so that the swing blade 21 is connected to the driving structure power, and the driving structure is separated from the air duct 11, so as to avoid blocking the airflow and thus affecting the air volume, and reduce wind noise.

[0044] Therefore, by hiding the driving structure of the swing blade assembly 2 and reducing the number of structural parts in the air duct 11, the phenomenon of water dripping after water accumulation in the air conditioner 100 is reduced during long-term use of the air conditioner 100, thereby increasing the service life of the air conditioner, reducing the obstruction of the air volume to the structural parts in the air duct 11, and increasing the air volume. In addition, the structure at the outlet end of the air duct 11 is small, keeping the structure of the air outlet end simple and neat.

[0045] According to the air conditioner 100 of the embodiment of the utility model, by arranging part of the structure of the crank 22 and the driving structure in the installation space 12, and the installation space 12 is separated from the air duct 11, the crank 22 and the driving structure are hidden, which effectively avoids the generation of condensation at the installation position of the swing blade 21, effectively reduces the phenomenon of dripping after water accumulation in the air conditioner, and improves the service life of the air conditioner 100. It also avoids the connection position of the swing blade 21 blocking the airflow and thus affecting the air volume, reduces wind noise, and at the same time reduces the bloatedness of the air outlet, and improves the neatness of the air outlet structure and appearance.

[0046] In some embodiments, the crank 22 is provided with a first shaft 221, a connecting plate 222 and a second shaft 223. The first shaft 221 and the second shaft 223 are respectively connected to the two sides of the connecting plate 222 and extend in parallel and spaced apart in opposite directions. The first shaft 221 is connected to the driving structure, and the second shaft 223 passes through the face frame 1 and is connected to the swing blade 21.

[0047] Specifically, the crank 22 includes three parts, namely a first shaft 221, a connecting plate 222 and a second shaft 223. The first shaft 221 and the second shaft 223 are connected by the connecting plate 222. Fig. 9 and Fig.10 As shown, the first shaft 221 and the second shaft 223 are respectively connected to the two sides of the connecting plate 222, and extend in opposite directions from the connecting plate 222 in parallel and spaced apart, and the extension length of the first shaft 221 is smaller than the extension length of the second shaft 223, and the outer diameter of the first shaft 221 is smaller than the outer diameter of the second shaft 223, wherein the first shaft 221 is connected to the driving structure, and the second shaft 223 passes through the face frame 1 and is connected to the swing blade 21, and the swing blade 21 can be connected to the driving structure through the crank 22, so that the driving structure drives the swing blade 21 to rotate.

[0048] Therefore, by making the above-mentioned settings of the crank 22, the crank 22 can be connected to the driving structure, and the second axis 223 penetrates the surface frame 1 to achieve connection with the swing blade 21, and the panel can separate the swing blade 21 in the air duct 11 from the driving structure of the installation space 12, which reflects a reasonable layout and meets the air outlet requirements.

[0049] In some embodiments, one of the second shaft 223 and the swing blade 21 is provided with a first positioning portion and the other is provided with a second positioning portion. The first positioning portion and the second positioning portion are plug-in positioned to make the second shaft 223 and the swing blade 21 relatively fixed in the circumferential direction. That is to say, the first positioning portion can be set on the second shaft 223 and the second positioning portion can be set on the swing blade 21, or the second positioning portion can be set on the second shaft 223 and the first positioning portion can be set on the swing blade 21. Both of these settings can achieve the plug-in positioning of the first positioning portion and the second positioning portion. Therefore, by setting the plug-in positioning of the first positioning portion and the second positioning portion, the circumferential limitation of the second shaft 223 and the swing blade 21 can be achieved.

[0050] And / or, one of the second shaft 223 and the swing blade 21 is provided with a first limiting portion and the other is provided with a second limiting portion, and the first limiting portion and the second limiting portion are plug-in limited to make the second shaft 223 and the swing blade 21 axially relatively fixed, that is, the first limiting portion can be set on the second shaft 223 and the second limiting portion can be set on the swing blade 21, or the second limiting portion can be set on the second shaft 223 and the first limiting portion can be set on the swing blade 21. Both of these settings can achieve the plug-in limit of the first limiting portion and the second limiting portion. Therefore, by setting the plug-in limit of the first limiting portion and the second limiting portion, the axial limit of the second shaft 223 and the swing blade 21 can be achieved.

[0051] Therefore, when the second shaft 223 and the swing blade 21 are installed, the first positioning portion and the second positioning portion are plugged in for positioning, and the first limiting portion and the second limiting portion are plugged in for limiting, so as to realize circumferential positioning and axial limiting of the second shaft 223 and the swing blade 21, and thus realize axial and circumferential limiting, thereby ensuring that the second shaft 223 and the swing blade 21 are more firmly and reliably connected.

[0052] In some embodiments, the first positioning portion is configured as a positioning groove 211, and the first limiting portion is configured as a limiting groove 213. The positioning groove 211 is connected to the limiting groove 213 and is open toward the same side. Specifically, as Figure 7 and Figure 8 As shown, a first positioning portion and a first limiting portion are provided at the bottom of the swing blade 21, the first positioning portion is configured as a positioning groove 211, the positioning groove 211 extends in one direction, and the first limiting portion is configured as a limiting groove 213, the limiting groove 213 and the positioning groove 211 extend in the same direction, wherein the limiting groove 213 and the positioning groove 211 can extend radially, and the positioning groove 211 and the limiting groove 213 are both provided with an open side and open to the same side, and the size of the limiting groove 213 is larger than the size of the positioning groove 211, the limiting groove 213 is located on the upper side of the positioning groove 211, and the two are connected, which is convenient for the processing of the limiting groove 213 and the positioning groove 211.

[0053] The second positioning portion is configured as a positioning block 2231, and the second limiting portion is configured as a limiting block 2233. The positioning block 2231 is connected to the limiting block 2233. Specifically, Fig. 9 and Fig.10 As shown, a second positioning portion and a second limiting portion are provided at the end of the crankshaft, the first limiting portion is located on the upper side of the second positioning portion, the second positioning portion is constructed as a positioning block 2231, the size of the positioning block 2231 is smaller than the size of the positioning groove 211, and the second limiting portion is constructed as a limiting block 2233, the size of the limiting block 2233 is smaller than the size of the limiting groove 213, the limiting block 2233 and the positioning block 2231 extend in the same direction, wherein the limiting block 2233 is connected to the positioning block 2231, the limiting block 2233 and the positioning block 2231 can extend axially, and the size of the limiting block 2233 is larger than the size of the positioning block 2231, and a guide surface 2235 is provided at the end of the limiting block 2233 away from the positioning block 2231, which is convenient for the installation of the limiting block 2233 and the limiting groove 213, and the structures of the positioning block 2231 and the limiting block 2233 are simple and easy to process.

[0054] Among them, when the positioning block 2231 is inserted into the positioning groove 211, the limit block 2233 is inserted into the limit groove 213. That is to say, the positioning block 2231 and the limit block 2233 are respectively inserted into the positioning groove 211 and the limit block 2233 at the same time, which can realize the insertion positioning of the positioning block 2231 and the insertion limiting of the limit block 2233, and realize the positioning and limiting connection between the second shaft 223 and the swing blade 21 through one action.

[0055] Therefore, when the swing blade 21 and the crank 22 are installed, the positioning block 2231 and the limiting block 2233 of the second shaft 223 of the crank 22 are inserted into the positioning groove 211 and the limiting groove 213 of the swing blade 21, so that the second shaft 223 and the swing blade 21 can be installed and fixed. The assembly diagram of the swing blade 21 and the crank 22 is shown in FIG. Figure 5 and Figure 6 As shown, the installation method is simple and the operation is convenient.

[0056] In some embodiments, the side surfaces of the positioning block 2231 facing away from each other are provided with a first anti-rotation surface 2232, and the wall surfaces relatively distributed in the positioning groove 211 are provided with a second anti-rotation surface 212, and the first anti-rotation surface 2232 is suitable for abutting against the second anti-rotation surface 212 along the circumferential direction of the swing blade 21. Specifically, as Fig. 9 As shown, the positioning block 2231 is provided with two first anti-rotation surfaces 2232, the two first anti-rotation surfaces 2232 are relatively distributed and are respectively located on the side surfaces of the positioning block 2231 that are away from each other, as shown in FIG. Figure 7As shown, the positioning groove 211 is provided with two second stop surfaces 212, and the two second stop surfaces 212 are relatively distributed and respectively located at the relatively distributed sides of the positioning groove 211, and the two first stop surfaces 2232 are arranged in parallel with the two second stop surfaces 212, and the distance between the two first stop surfaces 2232 is slightly larger than the distance between the two second stop surfaces 212. Therefore, the positioning block 2231 is inserted into the positioning groove 211, and the first stop surface 2232 and the second stop surface 212 are stop-connected, so that the swing blade 21 and the second shaft 223 are positioned along the circumferential direction to avoid circumferential rotation between the two. In this way, the connection is firm and the positioning is reliable.

[0057] And / or, the limiting groove 213 is formed as a first limiting surface 214 on the side adjacent to the positioning groove 211, and the side of the limiting block 2233 facing the positioning block 2231 is configured as a second limiting surface 2234, and the first limiting surface 214 is suitable for abutting against the second limiting surface 2234 along the axial direction of the swing blade 21. Specifically, as Figure 7 As shown, the limiting groove 213 is provided with a first limiting surface 214, and the first limiting surface 214 is provided at the connection between the limiting groove 213 and the positioning groove 211, that is, the first limiting surface 214 is provided on the side adjacent to the positioning groove 211, as shown in FIG. Fig. 9 As shown, the limit block 2233 is provided with a second limit surface 2234, and the second limit surface 2234 is arranged at the connection between the limit block 2233 and the positioning block 2231, that is, the second limit surface 2234 faces the side of the positioning block 2231, and the first limit surface 214 and the second limit surface 2234 are arranged in parallel. Therefore, the limit block 2233 is inserted into the limit groove 213, and the first limit surface 214 and the second limit surface 2234 are stopped, so that the swing blade 21 and the second shaft 223 are limited in the axial direction to avoid axial movement between the two. In this way, the insertion is firm and the limitation is reliable.

[0058] Thus, the circumferential and axial limitations of the swing blade 21 and the second shaft 223 can be achieved simultaneously by the first anti-rotation surface 2232 abutting against the second anti-rotation surface 212 and the first limiting surface 214 abutting against the second limiting surface 2234. Figure 5 and Figure 6 As shown, the circumferential rotation and axial movement of the swing blade 21 are avoided, ensuring that the swing blade 21 is reliably connected to the second shaft 223.

[0059] It should be noted that the first limiting surface 214, the second limiting surface 2234, the first anti-rotation surface 2232 and the second anti-rotation surface 212 can be processed by cutting, and the cutting process is simple and convenient.

[0060] In some embodiments, the second shaft 223 is provided with a second positioning portion and a second limiting portion, and the second shaft 223 also includes a shaft body portion 2236, which is rotatably inserted into the face frame 1, and the second positioning portion and the second limiting portion are both connected to one end of the shaft body portion 2236, and the other end of the shaft body portion 2236 is connected to the connecting plate 222.

[0061] Specifically, the second shaft 223 has three parts, namely a second positioning part, a second limiting part and a shaft body part 2236. Fig. 9 and Fig.10 As shown, the second positioning portion and the second limiting portion are connected to one end of the shaft body portion 2236, and the second positioning portion, the second limiting portion and the shaft body portion 2236 extend in the same direction, wherein the second limiting portion is located at the end of the second shaft 223, the second limiting portion is connected to the second positioning portion, one end of the shaft body portion 2236 is connected to the second positioning portion, and the other end is connected to the connecting plate 222, wherein the outer diameter of the shaft body portion 2236 is the largest, the shaft body portion 2236 is penetrated by the face frame 1, and is rotatable relative to the face frame 1, and as shown Fig.11 As shown, a connecting hole 13 is provided in the face frame 1, and the inner diameter of the connecting hole 13 is larger than the outer diameter of the shaft body 2236. The shaft body 2236 is inserted into the connecting hole 13, and the second shaft 223 can be connected to the face frame 1 to achieve the installation and fixation of the crank 22.

[0062] In some embodiments, the driving structure includes a driving member and a pull rod 231, the driving member is dynamically connected to the pull rod 231, the pull rod 231 is provided with a first connecting hole 232, the first shaft 221 is passed through the first connecting hole 232 to be rotatably connected to the pull rod 231, in this way, the first shaft 221 is rotatably connected to the pull rod 231, and the driving member is connected to the pull rod 231, so that the driving member drives the pull rod 231 to drive the first shaft 221 to rotate.

[0063] Specifically, the driving member is connected to the pull rod 231 by power, and the driving member can directly drive the pull rod 231 to move, wherein the first shaft 221 is passed through the pull rod 231, and the pull rod 231 is provided with a first connecting hole 232, such as Figure 4 As shown, the first connecting hole 232 can be constructed as a long hole, and the extension direction of the first connecting hole 232 is set along the length direction of the pull rod 231, and the first shaft 221 passes through the first connecting hole 232, and the first shaft 221 can rotate relative to the pull rod 231, wherein the driving member can be a driving motor, the driving motor drives the pull rod 231 to move, and the first shaft 221 swings along the first connecting hole 232 with the pull rod 231 to realize the rotation of the swing blade 21.

[0064] Therefore, since the face frame 1 is installed on the shaft body 2236, the face frame 1 is separated from the first shaft 221 by the connecting plate 222, so as to separate the air duct 11 and the installation space 12. In this way, when air is discharged from the air duct 11, the air outlet direction is changed by adjusting the rotation angle of the swing blade 21, and the driving member and the pull rod 231 for installing the swing blade 21 are both located in the installation space 12, which will not form resistance to the air outlet, thereby increasing the air outlet volume, reducing noise, and achieving a better use effect.

[0065] In some embodiments, an installation guide portion 2211 is provided at one end of the first shaft 221 away from the connecting plate 222, and the installation guide portion 2211 is configured as a conical surface. Thus, the installation guide portion 2211 facilitates the installation of the first shaft 221 and the pull rod 231, and the installation is convenient.

[0066] Specifically, the end of the first shaft 221 is provided with a mounting guide portion 2211, and is arranged at an end away from the connecting plate 222, and the mounting guide portion 2211 is configured as a conical surface, such as Fig.10 As shown, the conical surface is arranged to be inclined from the end of the first shaft 221 toward the direction of the connecting plate 222, which can play a guiding role. When the first shaft 221 and the pull rod 231 are installed, the first shaft 221 can be quickly installed in the first connecting hole 232 through the conical surface, thereby improving the installation speed of the first shaft 221 and the pull rod 231. The conical surface is provided with a limiting surface at one end close to the connecting plate 222, which can prevent the first shaft 221 from being separated from the connecting hole 13, realize the axial limitation of the pull rod 231 and the first shaft 221, and ensure the reliable installation of the first shaft 221.

[0067] In some embodiments, there are multiple swing blades 21 and cranks 22 , and the multiple cranks 22 are connected to the multiple swing blades 21 in a one-to-one correspondence, and the first shafts 221 of the multiple cranks 22 are connected to the pull rod 231 at intervals.

[0068] Specifically, Figure 1 and Figure 4 As shown, multiple swing blades 21 and multiple cranks 22 are connected one-to-one, wherein the pull rod 231 extends along the length direction of the air outlet of the air conditioner 100, and the multiple swing blades 21 and the multiple cranks 22 are evenly spaced and distributed on the pull rod 231. The pull rod 231 is provided with a plurality of first connecting holes 232, and the plurality of first connecting holes 232 are evenly spaced and distributed along the length direction of the pull rod 231. The first axes 221 of the plurality of cranks 22 are installed one-to-one with the plurality of first connecting holes 232, thereby realizing the installation of the cranks 22 and the pull rod 231.

[0069] Therefore, during the actual installation, after the second axes 223 of the multiple cranks 22 pass through the surface frame 1, the multiple swing blades 21 are positioned and plugged into the second axes 223 of the multiple cranks 22, and the first axes 221 of the multiple cranks 22 are installed on the pull rod 231. The pull rod 231 is also connected to the driving member. After the driving member drives the pull rod 231 to move, it can drive the multiple cranks 22 and the multiple swing blades 21 to rotate at the same time. The air outlet direction can be adjusted by adjusting the direction of the swing blades 21, and the swing blades 21 are simple to install and easy to adjust.

[0070] In some embodiments, the swing blade 21 is arranged at the bottom inside the air duct 11, and the installation space 12 is located at the bottom outside the air duct 11. In this way, the installation space 12 is separated from the air duct 11, and the structural parts of the installation space 12 are separated from the air duct 11, which reduces obstruction to the air outlet of the air duct 11 and ensures sufficient air outlet.

[0071] Specifically, Figure 2 and Figure 3 As shown, the swing blade 21 is located at the bottom of the air duct 11, and is used to adjust the air outlet direction of the bottom of the air duct 11. The installation space 12 is located at the bottom outside the air duct 11, and is separated from the bottom of the air duct 11 by a panel, that is, one side of the panel is used for air outlet, and the other side is used to install the drive structure and crank 22 of the swing blade assembly 2. Hiding the drive assembly and the crank 22 can make the structural parts on the side of the air duct 11 of the panel fewer, reduce the bloat of the air outlet, improve the regularity of the air outlet structure, and avoid the generation of condensation at the pull rod 231, effectively prevent dripping after water accumulation in the air conditioner, and effectively improve the service life of the air conditioner.
