[0039] As described in the background, the existing vertical air conditioner has the problem that the fresh air sent by the vertical air conditioner directly blows on the human body, resulting in poor comfort of the human body. The inventor has found that the reason for this problem is that the vertical air conditioner is provided with an air duct assembly, which is used to form an air duct to guide the air entering from the air inlet of the vertical air conditioner to the air outlet. The air duct assembly includes a swing vane, a volute and a volute tongue arranged in the vertical direction, the volute and the volute tongue are oppositely arranged and jointly limit the air outlet, and the swing vane is arranged at the air outlet of the air duct and can swing left and right relative to the volute. However, the existing vertical air conditioner can only swing left and right to adjust the air supply direction, and the fresh air sent by the vertical air conditioner directly blows on the human body, resulting in poor comfort of the human body.

[0040] In view of the above technical problems, the air guide structure and the air conditioner provided by the present application, wherein the air guide structure includes a swing vane assembly, which is rotatably connected at the air outlet of the air duct. The swing vane assembly includes at least one swing vane, which is provided with a plurality of air guide openings and air guide pieces arranged in cooperation with the air guide openings in the vertical direction. One side of the air guide piece is connected to the lower edge of the air guide opening, and the other side extends towards the upper edge of the air guide opening, i.e. the air guide piece is arranged obliquely upwards at the air guide opening of the swing vane. When the swing vane is rotated to the flat state, the swing vane can close the air outlet, so that the fresh air can flow out from the air guide opening, and the air guide piece guides the fresh air flowing through the air guide opening obliquely upwards or obliquely downwards.

[0041] Compared with the swing leaf of the air conditioner in the related art which can only realize left and right swing functions, the air guide structure provided by the application can not only swing left and right, but also can be turned to a flat state to close the air outlet according to the needs of the user, so that the fresh air flows out from the air guide opening of the swing leaf, the fresh air can be guided obliquely upward or obliquely downward, the straight blowing of the fresh air to the human body is avoided, and the comfort of the human body is improved.

[0042] In order to make the above-mentioned purpose, features and advantages of the embodiments of the application more apparent, understandable and easier to understand, the technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0043] The air conditioner provided by the embodiments of the application is a floor standing air conditioner, also known as a cabinet air conditioner. The floor standing air conditioner is usually placed on the ground. The floor standing air conditioner comprises a shell, an air guide structure, an axial flow fan and an evaporator. The shell is provided with an air inlet and an air outlet. The air guide structure is arranged in the shell and forms an air duct. The air duct is in communication with the air inlet and the air outlet of the shell, so as to guide the air introduced by the air conditioner to the air outlet. The axial flow fan is arranged in the air duct and is used to drive the air of the external environment to flow into the air duct from the air inlet. The evaporator is arranged between the air inlet of the shell and the axial flow fan and is used to exchange heat with the air flowing into the air duct, so as to realize the refrigeration or heating of the air conditioner.

[0044] As shown in Figure 1 and Figure 2 , the air guide structure provided by the embodiments of the application comprises a volute 30, a volute tongue 20 and a swing leaf assembly 10. The volute tongue 20 and the volute 30 are oppositely arranged in the shell and jointly form an air duct 40. The air outlet of the air duct 40 is a long strip-shaped opening extending in the vertical direction. The opening is generally consistent with the shape of the human body, so as to increase the wind receiving area of the human body and accelerate the change of the body surface temperature of the human body. For example, the body surface temperature of the human body can be cooled down to make the human feel cool.

[0045] For the convenience of describing the embodiments, the vertical direction shown in the embodiments of the application can refer to the arrow direction shown in Figure 1 . The direction can be perpendicular to the ground. In addition, in order to improve the air supply effect, the extension direction of the air outlet of the shell can be consistent with the axis of the axial flow fan.

[0046] As shown in Figures 3 to 5As shown, the swing-leaf assembly 10 comprises at least one swing-leaf 11 arranged at the air outlet of the air duct 40 in the vertical direction, and the swing-leaf 11 is rotatable relative to the volute 30, i.e. the swing-leaf 11 is rotatable around the vertical direction, so that the swing-leaf 11 swings left and right at the air outlet to adjust the air supply direction of the air conditioner 100.

[0047] Further, the swing-leaf 11 is provided with a plurality of air guide openings 111 and a plurality of air guide fins 112. In the vertical direction, the plurality of air guide openings 111 are arranged on the swing-leaf 11 at intervals, and the plurality of air guide fins 112 are respectively arranged obliquely on the air guide openings 111. The air guide fins 112 can guide the fresh air flowing from the air guide openings 111 to blow obliquely upward or obliquely downward.

[0048] It should be understood that each of the air guide openings 111 is respectively provided with an air guide fin 112, and the air guide fin 112 is arranged obliquely at the air guide opening 111. For example, the air guide fin 112 can be arranged obliquely upward at the air guide opening 111, one side of the air guide fin 112 is connected to the lower edge of the air guide opening 111, and the other side of the air guide fin 112 extends toward the upper edge of the air guide opening 111 and forms a gap with the air guide opening 111.

[0049] Alternatively, the air guide fin 112 can be arranged obliquely downward at the air guide opening 111, one side of the air guide fin 112 is connected to the upper edge of the air guide opening 111, and the other side of the air guide fin 112 extends toward the lower edge of the air guide opening 111 and forms a gap with the air guide opening 111. The embodiment of the present application does not limit this.

[0050] Exemplarily, when the air conditioner 100 is in the cooling anti-direct-blow mode, the cooling anti-direct-blow mode referred to herein is a mode in which the air conditioner 100 is in a cooling state and the fresh air does not directly blow to the body, i.e. the cold air can be sent out obliquely upward. Since the cold air is heavy, the waterfall air supply is realized, so that the fresh air does not directly blow to the body, and the user comfort is improved.

[0051] Conversely, when the air conditioner 100 is in the heating anti-direct-blow mode, the heating anti-direct-blow mode referred to herein is a mode in which the air conditioner 100 is in a heating state and the fresh air does not directly blow to the body, i.e. the hot air can be sent out obliquely downward, so that the hot air gradually rises from the ground, thereby improving the user comfort.

[0052] As Figure 8 and Figure 9As shown, the embodiment of the present application takes the example of the air deflector 112 being arranged obliquely downward, and when the air conditioner 100 is in the cooling anti-direct blowing mode, the swing vane 11 can be adjusted to be in the flattened state; at this time, the swing vane 11 closes the air outlet of the air duct 40, and the air deflector 112 is located at the inner side of the air duct 40; then the cold air can only flow out obliquely upward through the air deflector 112 and the air deflector 111. Conversely, when the air conditioner 100 is in the heating anti-direct blowing mode, the swing vane 11 is reversely rotated and is in the flattened state; at this time, the swing vane 11 closes the air outlet of the air duct 40, and the air deflector 112 is located at the outer side of the air duct 40, then the hot air flows out obliquely downward through the air deflector 111 and the air deflector 112.

[0053] It should be noted that, referring to Figure 2 When the swing vane 11 of the air conditioner 100 is in the non-flattened state, the swing vane 11 does not close the air outlet of the air duct 40, and the fresh air can flow out from the gap between the air duct 40 and the swing vane 11. If the swing vane 11 is rotated, the left and right swing functions can be realized. Further, the air deflector 112 of the swing vane 11 can guide the fresh air to flow out obliquely upward or obliquely downward. In this way, when the air conditioner 100 is in the left and right swing state, the air deflector 112 on the swing vane 11 can simultaneously realize the up and down swing functions, so that the cooling and heating effects are more uniform.

[0054] Unlike the swing vane of the stand-type air conditioner in the related art, which can only realize the left and right swing functions and the discharged fresh air directly blows on the human body, resulting in poor comfort of the human body, the swing vane 11 of the air deflector structure provided by the present application can not only swing left and right, but also be rotated to the flattened state to close the air outlet of the air duct 40 according to the needs of the user, so that the fresh air flows out from the air deflector 111 of the swing vane 11, and the fresh air can be sent out obliquely upward or obliquely downward, avoiding the direct blowing of the fresh air and the cold air on the human body, and improving the comfort of the human body.

[0055] On the basis of the above embodiment, the swing vane assembly 10 provided in the embodiment of the present application includes at least one swing vane 11. For example, one swing vane 11 is arranged at the air outlet of the air duct 40. Each swing vane 11 is provided with a plurality of air deflectors 112, wherein the air deflectors 112 located at the same row in the vertical direction can be arranged at intervals. For example, the swing vane 11 is arranged at two air deflectors 111 at intervals at the same height position in the vertical direction, and each air deflector 111 is provided with an air deflector 112 having the same inclined direction. In this way, the heating and cooling effects of the air conditioner 100 can be more uniform.

[0056] Further, in the vertical direction, the plurality of guide vanes 112 in adjacent rows are staggered on the swing leaf 11. For the convenience of describing the embodiments of the present application, the guide vanes 112 in two adjacent rows can be defined as a first guide vane group and a second guide vane group. In the vertical direction, the first guide vane group is arranged above the second guide vane group, the first guide vane group can be spaced apart to provide a plurality of first guide vanes, the second guide vane group can be spaced apart to provide a plurality of second guide vanes, and the second guide vane is located between the two first guide vanes close to it, that is, the first guide vanes and the second guide vanes are staggered, and the inclination directions of the guide vanes of the two are the same. In this way, the uniformity of the heating and cooling effect of the air conditioner 100 can be further improved.

[0057] Referring to Figure 3 As shown in the above embodiments, the swing leaf assembly 10 can include a plurality of swing leaves 11, and the plurality of swing leaves 11 are all rotationally connected at the air outlet of the air duct 40. Specifically, the swing leaf assembly 10 includes a plurality of swing leaves 11 arranged side by side, and the extension directions of the plurality of swing leaves 11 are consistent with the vertical direction, that is, the plurality of swing leaves 11 are arranged in parallel. Each swing leaf 11 is rotationally connected at the air outlet of the air duct 40, and the plurality of swing leaves 11 can rotate synchronously.

[0058] For example, the swing leaf assembly 10 can include three swing leaves 11 arranged side by side, and at least one linkage rod 13 connecting each swing leaf 11, the linkage rod 13 connects the three swing leaves 11 together, and can realize synchronous rotation of the three swing leaves 11. It should be noted that the linkage rod 13 can be a rigid connecting rod, and the linkage rod 13 is horizontally arranged and connected with each swing leaf 11 respectively.

[0059] Further, in order to improve the rotation consistency of each swing leaf 11 in the swing leaf assembly 10, the swing leaf assembly 10 can be provided with a plurality of linkage rods 13, wherein one linkage rod 13 is arranged at the top and the bottom of the swing leaf 11 respectively, and a plurality of linkage rods 13 can be arranged at the middle part of the swing leaf 11.

[0060] Referring to Figure 4 and Figure 5 On the basis of the above embodiments, each swing leaf 11 is rotationally connected at the air outlet of the air duct 40. Specifically, in the vertical direction, each swing leaf 11 is provided with a first rotation shaft 113 and a second rotation shaft 114, wherein the first rotation shaft 113 is arranged at the top of the swing leaf 11, one end of the first rotation shaft 113 is fixedly connected with the top end of the swing leaf 11, and the other end of the first rotation shaft 113 is rotationally connected with the top end of the volute tongue 20. For example, the top end of the volute tongue 20 is provided with a first hinge hole matched with the first rotation shaft 113, and the first rotation shaft 113 is installed in the first hinge hole, so that the swing leaf 11 can rotate relative to the volute tongue 20 under the action of the driving force.

[0061] The second rotating shaft 114 is disposed at the bottom end of the oscillating blade 11. The second rotating shaft 114 can be disposed opposite to the first rotating shaft 113, and the rotation axes of the two are located on the same straight line. One end of the second rotating shaft 114 is fixedly connected to the bottom end of the oscillating blade 11, and the other end of the second rotating shaft 114 is rotatably connected to the bottom end of the volute tongue 20. For example, the bottom end of the volute tongue 20 is provided with a second hinge hole that mates with the second rotating shaft 114. The second rotating shaft 114 is installed in the second hinge hole so that the oscillating blade 11 can rotate relative to the volute tongue 20 under the action of driving force.

[0062] Furthermore, the oscillating blade assembly 10 provided in this embodiment of the invention also includes a drive motor 12 for providing driving force to the oscillating blades 11, the drive motor 12 being disposed on the top of the oscillating blades 11. The drive motor 12 can be selectively connected to one of the plurality of oscillating blades 11, the drive motor 12 providing driving force to this oscillating blade 11, and transmitting the driving force to the other oscillating blades 11 through the linkage rod 13, so that each oscillating blade 11 rotates synchronously.

[0063] Preferably, the drive motor 12 can be connected to the pendulum 11 located in the middle position, that is, the drive motor 12 is connected to the first rotating shaft 113 of the pendulum 11, and the driving force of the drive motor 12 can be transmitted to the pendulum 11 through the first rotating shaft 113 to make the pendulum 11 rotate. This arrangement can improve the uniformity of the driving force on each pendulum 11, thereby improving the consistency of synchronous rotation of each pendulum 11.

[0064] To further improve the stability of the rotation of each blade 11, in this embodiment of the invention, each blade 11 is also provided with at least one third rotating shaft 115, which is rotatably connected to the volute tongue 20. The third rotating shaft 115 is located between the first rotating shaft 113 and the second rotating shaft 114, and the rotation axis of the third rotating shaft 115 is parallel to the rotation axis of the first rotating shaft 113, or the rotation axis of the third rotating shaft 115 is on the same straight line as the rotation axis of the first rotating shaft 113; preferably, the rotation axes of the first rotating shaft 113, the second rotating shaft 114 and the third rotating shaft 115 are on the same straight line.

[0065] like Figure 6 and Figure 7 As shown, the volute tongue 20 is provided with a support beam 21 for the third rotating shaft 115 to rotate. The support beam 21 is provided with a mounting part 22. The mounting part 22 has a mounting hole 221 that mates with the third rotating shaft 115. The axial direction of the mounting hole 221 is consistent with the rotation axis of the third rotating shaft 115. The mounting part 22 is provided with an opening groove 222 on the side facing the swing blade 11. The opening groove 222 communicates with the mounting hole 221. The third rotating shaft 115 is embedded in the mounting hole 221 through the opening groove 222. Under the action of driving force, the third rotating shaft 115 can rotate relative to the mounting part 22.

[0066] It should be noted that when the swing leaf assembly 10 includes a plurality of swing leaves 11 arranged side by side, a plurality of mounting portions 22 can be arranged on the support beam 21 at intervals, and the plurality of mounting portions 22 can provide mounting positions for the plurality of third rotating shafts 115 at the same height. In this way, the stability of the rotation of each swing leaf 11 and the synchronous rotation of the swing leaves 11 can be improved.
