[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0051] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0052] Next, the air duct structure 100 according to the first embodiment of the present invention will be described with reference to the accompanying drawings.

[0053] like Figure 1 and Figure 2 As shown, the air duct structure 100 according to the embodiment of the present invention includes: a fan component 1, an air outlet frame 2 and a deflector 3, as shown in FIG. Figure 3As shown, a cross-flow duct 10 is defined in the fan component 1, an outlet duct 20 is defined in the outlet frame 2, an inlet 201 of the outlet duct 20 is connected to the outlet of the cross-flow duct 10, and the outlet frame 2 has an outlet 21 connected to the outlet duct 20. The fan component 1 provides a flowing airflow, and the airflow flows into the outlet duct 20 through the cross-flow duct 10 and flows out from the outlet 21 along the outlet duct 20.

[0054] The air outlet 21 includes a first air outlet 211 arranged at the top of the air outlet frame 2 and a second air outlet 212 arranged at the bottom of the air outlet frame 2. By arranging the first air outlet 211 located at the top of the air outlet frame 2 and the second air outlet 212 located at the bottom of the air outlet frame 2, the air duct structure 100 has a longer air supply distance and a stronger air supply capacity.

[0055] It is understandable that the air duct structure 100 of the present invention is used for air conditioning devices such as air conditioners, and the following description will be made using air conditioners as an example. The air conditioner using the air duct structure 100 of the present invention can achieve upper air outlet and lower air outlet, improve the air supply capacity, and increase the air outlet coverage of the air conditioner. Optionally, the first air outlet 211 and the second air outlet 212 can work independently and open and close independently to meet different air supply effects of the air conditioner.

[0056] Exemplarily, for example, when the air conditioner is cooling, the first air outlet 211 discharges air, the second air outlet 212 is closed, or the air volume discharged from the first air outlet 211 is greater than the air volume discharged from the second air outlet 212, so as to improve the situation where the cold air flowing out of the second air outlet 212 directly blows onto the human body, thereby improving the comfort of use of the air conditioner during cooling.

[0057] For example, when the air conditioner is heating, the second air outlet 212 is outputting air, the first air outlet 211 is closed, or the air output of the second air outlet 212 is greater than the air output of the first air outlet 211, the hot air can be sent to the feet first to warm the feet, improve the situation of hot head and cold feet, and enhance the steady-state thermal comfort of the human body.

[0058] For example, when the air conditioner is in the initial stage of cooling or heating, air is discharged simultaneously through the first air outlet 211 and the second air outlet 212 to quickly adjust the temperature of the room and the human body, shorten the transition time from the dynamic temperature adjustment process to the steady state, improve the heat exchange efficiency of the air conditioner, and meet the user's usage needs more quickly.

[0059] like Figure 4 and Figure 5As shown, the deflector 3 is fixedly arranged in the air outlet frame 2, and the deflector 3 has an air guide surface 31 arranged toward the inlet 201 of the air outlet duct 20, and the air guide surface 31 includes a first air guide surface 311 and a second air guide surface 312, the first air guide surface 311 is located above the second air guide surface 312, the first air guide surface 311 is extended upward in a direction away from the inlet 201, and the second air guide surface 312 is extended downward in a direction away from the inlet 201. The first air guide surface 311 is suitable for guiding the airflow in the air outlet duct 20 to the first air outlet 211, and the second air guide surface 312 is suitable for guiding the airflow in the air outlet duct 20 to the second air outlet 212, so as to increase the air volume of the first air outlet 211 and the second air outlet 212, and improve the air supply effect.

[0060] The deflector 3 is fixedly connected to the air outlet frame 2, and the airflow is guided only by the air guide surface 31 on the deflector 3. Compared with wind guide structures such as swinging air guide blades, the deflector 3 of the present invention has a simple structure, occupies a small space, is easy to arrange, and can reduce the difficulty of assembly and save manufacturing costs.

[0061] According to the air duct structure 100 of the embodiment of the present invention, the air volume of the first air outlet 211 and the second air outlet 212 can be increased and the air supply height range can be expanded by providing the deflector 3. The deflector 3 for deflecting air has a simple structure, occupies a small space, is easy to arrange, and can reduce the difficulty of assembly and save manufacturing costs.

[0062] In some embodiments of the present invention, the air duct structure 100 also includes a crossflow wind wheel 11 arranged in the crossflow wind wheel 10, the axial direction of the crossflow wind wheel 11 extends in the vertical direction, and the crossflow wind wheel 11 sends the airflow in a direction perpendicular to the axial direction of the crossflow wind wheel 11. Correspondingly, the crossflow air duct 10 is also arranged in the vertical direction, and the outlet of the crossflow air duct 10 extends in the horizontal direction, and the airflow flowing out from the outlet of the crossflow air duct 10 also flows in a horizontal direction perpendicular to the vertical direction.

[0063] In some embodiments of the present invention, Figure 5 As shown, the angle A1 between the first air guide surface 311 and the extension direction of the outlet of the crossflow air duct 10 is 110° to 170°. Optionally, the angle A1 is equal to 110°, 115°, 120°, 130°, 145°, 150°, 156°, 162°, 170°, etc.

[0064] In some embodiments of the present invention, Figure 5 As shown, the angle A2 between the second air guide surface 312 and the extension direction of the outlet of the crossflow air duct 10 is 110° to 170°. Optionally, the angle A2 is equal to 110°, 115°, 120°, 130°, 145°, 150°, 156°, 162°, 170°, etc.

[0065] It is worth noting that, since the crossflow wind wheel 11 provides a flowing airflow, the crossflow wind wheel 11 sends the airflow in a direction perpendicular to the axial direction of the crossflow wind wheel 11, and therefore the extension direction of the outlet of the crossflow wind duct 10 can be approximately regarded as the flow direction of the airflow from the crossflow wind duct 10 into the outlet wind duct 20. The angle A1 between the first air guide surface 311 and the extension direction of the outlet of the crossflow wind duct 10, and the angle A2 between the second air guide surface 312 and the extension direction of the outlet of the crossflow wind duct 10 can reflect the guiding effect of adjusting the direction of the airflow.

[0066] Among them, when the wind guide surface is parallel to the extension direction of the outlet of the cross-flow air duct 10, that is, the wind guide surface does not play a role in changing the wind direction, the angle between the wind guide surface and the extension direction of the outlet of the cross-flow air duct 10 is 180 degrees. In the present invention, by limiting the corresponding angle A1 of the first wind guide surface 311 to 110° to 170°, it is equivalent to the first wind guide surface 311 adjusting the airflow upward by 10° to 70°. The first wind guide surface 311 adjusts the airflow upward by at least 10°, which is conducive to the upward flow trend of the airflow, thereby helping to blow the airflow higher and farther. The first wind guide surface 311 adjusts the airflow upward by no more than 70°, which is used to avoid excessive airflow directly hitting the roof and causing rebound backflow to the air duct structure 100, which also helps to send the airflow higher and farther.

[0067] Similarly, by limiting the corresponding angle A2 of the second wind-guiding surface 312 to 110° to 170°, it is equivalent to the second wind-guiding surface 312 adjusting the airflow downward by 10° to 70°. The second wind-guiding surface 312 adjusts the airflow downward by at least 10°, which is conducive to the downward flow trend of the airflow, thereby helping to blow the airflow lower and farther. The second wind-guiding surface 312 adjusts the airflow downward by no more than 70°, which is used to avoid excessive airflow directly hitting the ground and causing rebound backflow to the air duct structure 100, which also helps to send the airflow lower and farther.

[0068] Therefore, setting the angle A1 between the first air guiding surface 311 and the extension direction of the outlet of the cross-flow air duct 10 within the above-mentioned range is beneficial to reducing the resistance of the airflow blowing out from the first air outlet 211, thereby facilitating the distribution of more airflow, which can increase the airflow volume of the first air outlet 211 and reduce the spatial volume occupied by the deflector 3, thereby facilitating the arrangement of the deflector 3.

[0069] Similarly, setting the angle A2 between the second air guide surface 312 and the extension direction of the outlet of the cross-flow air duct 10 within the above-mentioned range is beneficial to reducing the resistance of the airflow blowing out of the second air outlet 212, thereby facilitating the distribution of more airflow, which can increase the airflow volume of the second air outlet 212 and reduce the spatial volume occupied by the deflector 3, thereby facilitating the arrangement of the deflector 3.

[0070] In some embodiments of the present invention, Figure 5 As shown, the height dimension L1 of the first wind guiding surface 311 is 70 mm to 150 mm; the height dimension L2 of the second wind guiding surface 312 is 70 mm to 150 mm.

[0071] If the height dimension L1 of the first air guide surface 311 is too large or too small, it is not conducive to the air discharge of the first air outlet 211. The crossflow wind wheel 11 sends the airflow in a direction perpendicular to the axial direction of the crossflow wind wheel 11. If the height dimension L1 of the first air guide surface 311 is too small, it can only guide a smaller amount of airflow, thereby reducing the amount of airflow at the first air outlet 211. If the height dimension L1 of the first air guide surface 311 is too large, the dimension of the deflector 3 in the direction of the crossflow wind wheel 11 will be increased, and the space occupied by the deflector 3 will be increased, which is not conducive to the arrangement of the deflector 3.

[0072] By setting the height dimension L1 of the first wind guiding surface 311 within the above range, the first wind guiding surface 311 has a better guiding effect on the airflow, which can increase the airflow volume of the first air outlet 211 and reduce the space volume occupied by the deflector 3, thereby facilitating the arrangement of the deflector 3.

[0073] Similarly, by setting the height dimension L2 of the second wind guide surface 312 within the above range, the second wind guide surface 312 has a better guiding effect on the airflow, which can increase the airflow volume of the second air outlet 212 and reduce the space volume occupied by the deflector 3, thereby facilitating the arrangement of the deflector 3.

[0074] In some embodiments of the present invention, the wind guide surface 31 includes a plane and / or a curved surface. The shape of the wind guide surface 31 can be selected according to actual needs. The shapes of the first wind guide surface 311 and the second wind guide surface 312 can be consistent, or the shapes of the first wind guide surface 311 and the second wind guide surface 312 can be inconsistent.

[0075] In some embodiments of the present invention, Figure 6 As shown, the first wind guide surface 311 and the second wind guide surface 312 are both planes. The wind guide surface 31 has a simple structure, and the wind guide surface 31 is set to have an angle between 110° and 170° with the extension direction of the outlet of the crossflow air duct 10 to meet the flow guiding effect.

[0076] In other embodiments of the present invention, Figure 7 As shown, the first air guiding surface 311 and the second air guiding surface 312 are both curved surfaces. The angle between the tangent line of at least one point in the cross-sectional direction of the air guiding surface 31 and the extension direction of the outlet of the cross-flow air duct 10 can be set in the range of 110° to 170°. Compared with a plane, a curved surface is more in line with the flow direction of the airflow, thereby further improving the air outlet effect of the air duct structure 100.

[0077] In some embodiments of the present invention, Figure 7As shown, the first air guide surface 311 and the second air guide surface 312 can be arc surfaces that are concave along the airflow direction. Compared with designing the first air guide surface 311 or the second air guide surface 312 as an arc surface that is convex toward the airflow direction, the phenomenon of airflow impacting the first air guide surface 311 or the second air guide surface 312 and causing reflection can be reduced, thereby improving the fluidity of the airflow and improving the air outlet effect.

[0078] In some embodiments of the present invention, Figure 1 As shown, the air outlet 21 of the air outlet frame 2 further includes: a third air outlet 213 , and the third air outlet 213 is located between the first air outlet 211 and the second air outlet 212 .

[0079] It can be understood that the crossflow wind wheel 11 is arranged in the crossflow wind duct 10 along the vertical direction, and the crossflow wind wheel 11 sends the airflow in the direction perpendicular to the axial direction of the crossflow wind wheel 11, so the first air outlet 211 arranged at the top of the air outlet frame 2 and the second air outlet 212 arranged at the bottom plate of the air outlet frame 2 only guide part of the airflow, and the third air outlet 213 arranged between the first air outlet 211 and the second air outlet 212 is the main air outlet 21 of the air duct structure 100. The air duct structure 100 of the present invention can not only discharge air through the top of the first air outlet 211 and the bottom of the second air outlet 212, but also discharge air in large volume through the third air outlet 213.

[0080] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, there are two third air outlets 213 arranged horizontally at intervals, so as to increase the air supply range of the air duct structure 100 in the horizontal direction and improve the air supply effect.

[0081] like Figure 2 and Figure 3 As shown, the third air outlet 213 includes a left air outlet 2131 extending toward the left and a right air outlet 2132 toward the right, and the two third air outlets 213 are in opposite directions, so that the air supply range of the air duct structure 100 in the horizontal direction can be improved. When the air duct structure 100 is used in an air conditioner, the air conditioner using the air duct structure 100 of the present invention can also achieve left and right side air outlets at the front, further improving the air outlet coverage of the air conditioner. The left and right directions here are based on the directions when the air duct structure 100 shown in the drawings is working normally, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the air duct structure 100 must be constructed in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0082] In some embodiments of the present invention, Figure 8As shown, the deflector 3 has two flow dividing surfaces 32 arranged toward the inlet 201 of the air outlet duct 20, the two flow dividing surfaces 32 are located between the two third air outlets 213, and the two flow dividing surfaces 32 are located between the first air guiding surface 311 and the second air guiding surface 312. Figure 3 As shown, two diverter surfaces 32 are adjacently arranged at one side of the inlet 201 , and the two diverter surfaces 32 include a first diverter surface 321 extending toward one third air outlet 213 and a second diverter surface 322 extending toward another third air outlet 213 , so as to guide the airflow to flow toward the two third air outlets 213 .

[0083] The adjacent sides of the first diverter surface 321 and the second diverter surface 322 are arranged close to the inlet 201 of the air outlet duct 20, and the first diverter surface 321 extends toward the left air outlet 2131, and the first diverter surface 321 is suitable for guiding the airflow in the air outlet duct 20 to the left air outlet 2131; the second diverter surface 322 extends toward the right air outlet 2132, and the second diverter surface 322 is suitable for guiding the airflow in the air outlet duct 20 to the right air outlet 2132, so as to enhance the air outlet effect of the two third air outlets 213.

[0084] Alternatively, if Fig.10 and Fig.12 As shown, the two flow dividing surfaces 32 are not directly connected to each other, so as to improve the structural strength of the flow guide 3 and reduce the volume of the flow guide 3. Optionally, the two flow dividing surfaces 32 are connected at one side adjacent to the inlet 201 to improve the integrity.

[0085] In some embodiments of the present invention, Fig. 9 As shown, the deflector 3 includes a deflector seat 3a and a diverter plate 3b, and the deflector 3 is easy to disassemble and assemble. In other embodiments of the present invention, the deflector 3 is an integrally formed part, which can improve the integrity of the deflector 3. Figure 8 and Fig. 9 As shown, a first air guide surface 311 and a second air guide surface 312 are provided on the guide seat 3a, and a diverter plate 3b is installed on the side of the guide seat 3a facing the inlet 201, and the diverter plate 3b is located between the first air guide surface 311 and the second air guide surface 312 in the vertical direction, and at least a portion of the first diverter surface 321 and at least a portion of the second diverter surface 322 are formed on the diverter plate 3b.

[0086] In some embodiments of the present invention, Figure 8 and Fig. 9 As shown, the deflector 3 is constructed as a protruding structure with a middle portion protruding toward the inlet 201 of the air outlet duct 20 and two ends extending in a direction away from the inlet 201 of the air outlet duct 20. Fig.10 As shown, the guide seat 3a and the splitter plate 3b are both constructed as a structure with the middle portion protruding toward the inlet 201 of the air outlet duct 20, and as shown in FIG.
