Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0040] Traditional air conditioning systems often use mechanical air supply methods, with high wind speed and uneven air supply, which can cause user discomfort and seriously affect user experience after long-term use. In the technical field of air conditioners, windless air conditioners have been developed.

[0041] Currently, a common way to increase the air diffuser assembly is to increase the air diffuser assembly. However, the air conditioner using the air diffuser technology currently has the problems of small air volume, poor heat exchange efficiency, and slow change rate of indoor environment temperature.

[0042] For this purpose, please refer to Fig. 1 to Fig. 2 The air duct 11 structure provided by the embodiments of the present application includes a shell 10 and a soft wind plate 20. The shell 10 is formed with an air duct 11 and an air outlet 12 communicating with the air duct 11. The soft wind plate 20 is rotatably installed at the air outlet 12 of the shell 10, and the soft wind plate 20 is provided with a flow distribution part 21. The soft wind plate 20 has a soft wind position in its rotation stroke. When the soft wind plate 20 is located at the soft wind position, the soft wind plate 20 partially blocks the air outlet 12 of the shell 10 to distribute the airflow passing through the soft wind plate 20 through the flow distribution part 21. The two ends of the soft wind plate 20 in the width direction are at least partially spaced apart from the shell 10 to define two flow channels 23. The flow rate of the gas flowing out of the flow channel 23 is greater than the flow rate of the gas after being distributed by the flow distribution part 21.

[0043] The two ends of the flexible air baffle 20 in the width direction are at least partially spaced apart from the shell 10, so that two flow channels 23 are defined, and the flow rate of the gas flowing out of the flow channels 23 is greater than the flow rate of the gas after being diffused by the diffusion part 21. Therefore, the air outlet at the air outlet 12 is the low-flow-rate gas diffused by the diffusion part 21, and on both sides of the low-flow-rate gas, it is the high-flow-rate gas flowing out of the flow channels 23. The flow rates of the three airflows are different, forming a pressure difference, so that the airflows interfere with each other at the air outlet 12, effectively increasing the turbulence, thereby achieving windless feeling while increasing the air volume of the air conditioner, and increasing the amount of airflow for heat exchange of the heat exchanger, thereby improving the heat exchange efficiency of the heat exchanger, and further improving the indoor environment temperature change rate.

[0044] It can be understood that the flexible air baffle 20 partially blocks the air outlet 12 of the shell 10, which can effectively increase the air volume at the air outlet 12 compared to the scheme in which the flexible air baffle 20 blocks the air outlet 12 of the shell 10 as a whole.

[0045] It should be noted that the specific form of the shell 10 is not limited, which can be in the form of a volute, or in the form of a combination of a middle frame, a base 16 and an air baffle, etc. The specific implementation form of the diffusion part 21 is not limited, which can be in the form of a plurality of diffusion holes, wherein the diffusion holes can be partially provided as through holes, partially provided as blind holes, or all provided as through holes. The specific form of the flow channel 23 is not limited, which can be in the form of a slot formed at both ends of the flexible air baffle 20 in the width direction, so as to form the flow channel 23, or in the form of a mounting seat protruding on the mouth wall of the air outlet 12, so that both ends of the flexible air baffle 20 in the width direction are at least partially spaced apart from the shell 10, or in the form of hoisting the flexible air baffle 20, etc.

[0046] The two ends of the flexible air baffle 20 in the width direction are at least partially spaced apart from the shell 10, which can be only partially spaced apart, or can be completely spaced apart, without limitation. The flow channel 23 can be formed by the two ends of the flexible air baffle 20 and the mouth wall of the air outlet 12, or can be formed by the flexible air baffle 20 and other components, such as the air baffle, without limitation.

[0047] Further, please refer to Fig. 5 to Fig. 6In an embodiment, the air flow channel 23 is formed by the air flow groove 22 and the wall of the air outlet 12. When the soft air panel 20 is installed on the air outlet 12, the air flow channel 23 is formed by the air flow groove 22 and the wall of the air outlet 12. Therefore, the wall of the air outlet 12 does not need to be outwardly protruding.

[0048] Specifically, the air flow groove 22 can be formed at both ends of the soft air panel 20 in the width direction, or can be formed by rotating installation portions at one end of the soft air panel 20, or can be formed by spacing the rotating installation portions, and the like.

[0049] Further, the depth of the air flow channel 23 is not limited. It can be understood that the smaller the size of the air flow channel 23 is, the greater the flow rate of the gas flowing out of the air flow channel 23 is. Therefore, when the soft air panel 20 is in the soft air position, the size of the air flow channel 23 in the width direction of the soft air panel 20 is a, wherein 1mm≤a≤10mm. In this way, a is less than or equal to 10mm, so that the flow rate of the high-flow-rate gas flowing out of the air flow channel 23 can be greater than a certain value. At the same time, a is greater than or equal to 1mm, so that the soft air panel 20 and the shell 10 can maintain a certain distance. On the one hand, the amount of high-flow-rate gas will not be too small because the size of the air flow channel is too small. On the other hand, the soft air panel 20 can avoid interference with other components during rotation.

[0050] Please refer to Fig. 5 and Fig. 6 In some embodiments, the soft air panel 20 has a first side and a second side arranged opposite to each other in the thickness direction of the soft air panel 20. When the soft air panel 20 is in the soft air position, the first side 24 of the soft air panel faces the air duct 11. The air diffusion portion 21 includes a plurality of air diffusion grooves 29 formed on the second side 25 of the soft air panel. The air diffusion grooves 29 penetrate the first side 24 of the soft air panel in the thickness direction of the soft air panel 20, so that the air flowing to the soft air panel 20 can pass through the soft air panel 20 from the air diffusion grooves 29. The plurality of air diffusion grooves 29 include a first air diffusion groove 26 extending in a first direction on the second side 25 of the soft air panel and a second air diffusion groove 28 extending in a second direction. The first direction and the second direction are arranged in an intersecting manner on the first side 24 of the soft air panel.

[0051] Corresponding to the technical solutions in the embodiment, when the flexible wind plate 20 is in the flexible wind position, the airflow in the air duct 11 impacts the second side 25 of the flexible wind plate, and after the flow rate is reduced, the airflow flows to the air diffuser groove 29 and the periphery of the flexible wind baffle. A part of the airflow flows to the first side 24 of the flexible wind plate from the air diffuser groove 29 which is arranged in a penetrating manner. Another part of the airflow moves along the direction of the air diffuser groove 29. Since the first direction and the second direction are arranged in an intersecting manner on the first side 24 of the flexible wind plate, at this time, the two airflows flowing in the first direction and the second direction interfere with each other, increase the turbulence degree, and further disorder the airflow organization, thereby avoiding the airflow from directly blowing on the user.

[0052] Further, the air outlet 12 of the common indoor wall-mounted machine has a false air outlet 13 due to internal structure and aesthetic factor design, and the false air outlet 13 is easy to cause the inner surface of the air deflector to be too cold and the outer surface to contact with the hot and humid air to generate condensation problems.

[0053] To this end, in some embodiments, the shell 10 is further formed with a false air outlet 13 which is in communication with the air duct 11, the false air outlet 13 is located on one side of the air outlet 12, and the flexible wind baffle extends to the false air outlet 13. The blind groove 27 is arranged on the flexible wind plate 20, and the blind groove 27 is arranged at least on the second side in the area of the false air outlet 13.

[0054] In this way, by arranging the blind groove 27 on the second side in the area of the false air outlet 13, when the airflow flows to the area of the false air outlet 13, the airflow cannot flow out from the blind groove 27 due to the blocking effect of the blind groove 27, and can be guided by the blind groove 27 to flow to other areas, for example, to the overflow channel 23 which is jointly defined by the overflow groove 22 and the wall between the air outlet 12 and the air outlet 12. The air flux at the false air outlet 13 is effectively reduced, and the condensation phenomenon is slowed down.

[0055] It should be emphasized that the blind groove 27 can be arranged only on the second side 25 of the flexible wind plate in the area of the false air outlet 13, or can be arranged in the area outside the false air outlet 13 on the second side 25 of the flexible wind plate, which is not limited herein.

[0056] Please refer to Fig. 1 to Fig. 3 , Fig. 7 , Fig. 8 and Fig. 10 , the shell 10 includes a first air deflector 17 arranged at the air outlet 12, the flexible wind plate 20 has a first end and a second end in the width direction of the flexible wind plate 20. When the flexible wind plate 20 is in the flexible wind position, the first end of the flexible wind plate 20 is at least partially arranged in a spaced manner with the first air deflector 17 in the width direction of the flexible wind plate 20 to form one of the overflow channels 23.

[0057] Corresponding to the technical solutions in this embodiment, by setting the first air deflector 17, the airflow in the air duct 11 can be guided to the soft air deflector 20, and the first end of the soft air deflector 20 is at least partially spaced apart from the first air deflector 17 in the width direction of the soft air deflector 20 to form one of the flow-through channels 23. In this way, by adjusting the first air deflector 17, the flow direction of the airflow can also be adjusted.

[0058] In addition, in order to prevent the problem of condensation at the false air outlet 13, please refer to Fig. 3 , Fig. 7 and Fig. 8 In some embodiments, the shell 10 is also formed with a false air outlet 13 communicating with the air duct 11, the false air outlet 13 is located on one side of the air outlet 12, and the soft air deflector extends to the false air outlet 13; the first air deflector 17 corresponds to the false air outlet 13 and is provided with a first flow barrier rib 14, and when the soft air deflector 20 is in the soft air position, the first flow barrier rib 14 is used to block the gap between the first air deflector 17 and the soft air deflector 20.

[0059] Corresponding to the technical solutions in this embodiment, by setting the first flow barrier rib 14, when the soft air deflector 20 is in the soft air position, the first flow barrier rib 14 can block the part of the flow-through channel 23 located at the false air outlet 13, avoid the airflow flowing out from there, avoid the cold air directly blowing on the part of the first air deflector 17 located outside the first side 24 of the soft air deflector, reduce the air flux at the false air outlet 13, improve the problem that the cold air easily flows along the air deflector to the false air outlet 13, causing condensation to easily occur at the false air outlet 13, and improve the problem of excessive condensate dripping.

[0060] At the same time, please refer to Fig. 4 In addition, the shell 10 can also include a base 16, the first air deflector 17 is provided with a second flow barrier rib 15 at the false air outlet 13, and when the soft air deflector 20 is in the soft air position, the second flow barrier rib 15 is extended and arranged towards the base 16 to block the gap between the base 16 and the first air deflector 17. In this way, by setting the second flow barrier rib 15, the gap between the base 16 and the first air deflector 17 can be blocked, avoiding the cold air flowing out from the gap between the base 16 and the wall, avoiding the cold air directly blowing on the part of the first air deflector 17 located outside the first side 24 of the soft air deflector, and improving the condensation problem of the base 16 and the first air deflector 17 located at the false air outlet 13.

[0061] It should be noted that the first flow barrier 14 and the second flow barrier 15 can be selectively arranged or both arranged, which is not limited herein, and the improvement effect on the condensation problem at the false air outlet 13 is better when both arranged, and therefore, in an embodiment, the first air deflector 17 is provided with both the first flow barrier 14 and the second flow barrier 15.

[0062] In addition, in an embodiment, the second flow barrier 15 extends to one end of the first air deflector 17 in the length direction, specifically, the first air deflector 17 in Fig. 7 and 8 , the second flow barrier 15 is arranged at the one end of the first air deflector 17 at the false air outlet 13 rotation shaft, and the length of the second flow barrier 15 in the length direction of the first air deflector 17 is B, if the distance from the right end surface of the first air deflector 17 to the right rotation shaft outer end surface of the first air deflector 17 is C, then B = C ± 3 mm, so that the cold air can be maximally avoided from directly blowing on the part of the first air deflector 17 outside the first side 24 of the soft air deflector. Correspondingly, in this embodiment, the height of the second flow barrier 15 is 1-5 mm.

[0063] In some embodiments, please refer to Fig. 3 , Fig. 7 , Fig. 8 and Fig. 10 , when the soft air deflector 20 is located at the soft air position, the first flow barrier 14 abuts against the first side 24 of the soft air deflector, and the first air deflector 17 cooperates with the soft air deflector 20 to abut against the first flow barrier 14, which can limit the rotation of the soft air deflector 20 and / or the first air deflector 17 by the first flow barrier 14, and on the other hand, the first flow barrier 14 abuts against the first side 24 of the soft air deflector, which has a better sealing effect on the gap between the first air deflector 17 and the soft air deflector 20.

[0064] Correspondingly, when the cold air flows to the false air outlet 13, since the blind groove 27 is arranged at the corresponding false air outlet 13 of the soft air deflector 20, no air is blown at the part corresponding to the soft air deflector 20, and the gap between the soft air deflector 20 and the first air deflector 17 is sealed by the first flow barrier 14, so no air is blown, and the cold air can only flow out from the flow channel 23 defined between the flow-through groove 22 and the wall of the air outlet 12, and cannot directly blow on the part of the first air deflector 17 outside the first side 24 of the soft air deflector, thereby avoiding the generation of condensation.

[0065] It is emphasized that the height of the first baffle rib 14 is not limited as long as it can block the gap between the flexible air baffle 20 and the first air deflector 17, and in an embodiment, the height of the first baffle rib 14 is 3-10mm; it cooperates with the flexible air baffle 20 to abut and block the cold air directly blowing the inner surface of the right end of the first air deflector 17, and at this position, the first baffle rib 14 and the flexible air baffle 20 overlap with a height of 1mm-9mm.

[0066] In further embodiments, referring to Fig. 9 , the shell 10 further comprises a second air deflector 18 arranged at the air outlet 12, when the flexible air baffle 20 is in the flexible air position, the second air deflector 18 is arranged on the side of the first air deflector 17 away from the flexible air baffle 20, and is spaced apart from the first air deflector 17, and the second air deflector 18 is further provided with a protrusion 19 extending towards the first air deflector 17.

[0067] Corresponding to the technical solution in the present embodiment, by arranging the second air deflector 18 and the protrusion 19, the high-speed airflow can be guided to the outer surface of the first air deflector 17, and according to the Coanda effect, the low-speed airflow outside the first air deflector 17 is sucked forward, thereby effectively increasing the air flow at the first air deflector 17 and supplementing the airflow at the first air deflector 17.

[0068] The utility model also proposes a kind of air conditioner 100, the air conditioner 100 includes air duct 11 structure, the specific structure of this air duct 11 structure refers to above-mentioned embodiment, since the air conditioner 100 of the present application adopts all technical solutions of above-mentioned all embodiments, at least has all beneficial effects brought by the technical solution of above-mentioned embodiment, here no longer one by one elaboration.
