[0040] Figure 1 is a schematic structural diagram of the second plate 130 according to an embodiment of the present utility model, such as Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the utility model provides an air guide device 10 for an air conditioner, comprising a first plate body 110, a second plate body 130 and an air dispersion device 70. A plurality of first air outlet holes are arranged on the first plate body 110. The second plate body 130 is arranged on one side of the first plate body 110, and the first plate body 110 and the second plate body 130 are arranged at intervals to form an air guide interval 150. A plurality of second air outlet holes 140 are arranged on the second plate body 130. The air dispersion device 70 is arranged in the air guide interval 150, and is located at a position directly opposite to the first air outlet hole, so as to guide all or part of the airflow from the first air outlet hole.

[0041] In this embodiment, the first air outlet is directly opposite to the wind dispersing device 70. When the wind guide device 10 guides the wind, the airflow is blown from the first air outlet to the wind dispersing device 70. The airflow diffuses to the surroundings along the surface of the wind dispersing device 70 in the wind guide interval 150. When the airflow diffuses to the second air outlet 140, it flows from the second air outlet 140 to the room, achieving a windless feeling when the air conditioner blows out air. The wind dispersing device 70 disperses the airflow, converts the strong wind blown out by the air conditioner into soft wind and blows it into the room, so as to prevent the strong wind blown out by the air conditioner from directly blowing on the user, thereby improving the user experience.

[0042] Furthermore, the airflow is diffused in the air guide space 150, and the air guide space 150 further improves the dispersion effect of the airflow, thereby improving the windless feeling of the air outlet of the air conditioner.

[0043] In some embodiments of the present invention, Figure 2 As shown, the wind dispersing device 70 includes a shielding structure 710, which defines an internal space 720 and at least one connecting hole 730. The inlet of the internal space 720 is aligned with the first air outlet to receive part or all of the airflow from the first air outlet. The connecting hole 730 connects the inner and outer sides of the internal space 720 in a direction parallel to the radial direction of the first air outlet.

[0044] In this embodiment, the shielding structure 710 includes an internal space 720 and a connecting hole 730. When the air guide device 10 guides air, the airflow blows from the first air outlet hole to the internal space 720, and flows into the air guide interval 150 through the connecting hole 730. The airflow flows to the second air outlet hole 140 in the air guide interval 150, and then flows into the room from the second air outlet hole 140. The airflow is dispersed by the shielding structure 710, and the strong wind blown by the air conditioner is converted into soft wind and blown into the room, so as to prevent the strong wind blown by the air conditioner from blowing directly on the user, thereby improving the user's experience.

[0045] In some embodiments of the present invention, Figure 2 As shown, the shielding structure 710 includes a plurality of shielding walls 711 , and the plurality of shielding walls 711 are arranged at intervals along the circumferential direction of the first air outlet to form at least two connecting holes 730 .

[0046] In this embodiment, the interval between two adjacent shielding walls 711 forms a connecting hole 730 to connect the inside and outside of the internal space 720, so that the airflow flows from the internal space 720 to the outside of the internal space 720, and then flows into the room from the second air outlet 140. The plurality of shielding walls 711 are arranged along the circumference of the first air outlet, and the connecting hole 730 is arranged along the circumference of the first air outlet, so that the airflow from the internal space 720 is evenly dispersed to the surroundings, improving the dispersion effect of the airflow, preventing the strong wind blown by the air conditioner from directly blowing the user, and improving the user experience.

[0047] In some embodiments of the present invention, Figure 2 As shown, the shielding structure 710 further includes a connecting ring 712 , and the connecting ring 712 is connected to the ends of the plurality of shielding walls 711 facing the first air outlet.

[0048] In this embodiment, the connecting ring 712 connects the ends of two adjacent shielding walls 711 , so that the structure of the wind dispersing device 70 is more stable, and the wind dispersing effect of the wind dispersing device 70 is improved.

[0049] In some embodiments of the present invention, the first air outlet holes and the second air outlet holes 140 are arranged alternately so that the airflow is changed in direction by the second plate 130 after entering the air guide space 150 through the first air outlet holes, and then flows out from the second air outlet holes 140 .

[0050] In this embodiment, the first air outlet and the second air outlet 140 are completely staggered, and the airflow passes through the first air outlet and blows to the surface of the second plate 130 facing the first plate 110, that is, the airflow blows to the inner surface of the second plate 130. The airflow flows along the inner surface of the second plate 130, and flows out from the second air outlet 140 when it flows to the second air outlet 140. The strong wind is converted into soft wind by the completely staggered first air outlet and second air outlet 140, so as to avoid the strong wind blown out from the first air outlet 30 directly blowing out from the second air outlet 140, and prevent the strong wind blown by the air conditioner from blowing directly to the user, thereby improving the user experience.

[0051] In some embodiments of the present invention, the first air outlet holes and the second air outlet holes 140 are arranged alternately, so that the airflow is changed in direction by the wind dispersion device 70 after entering the air guide space 150 through the first air outlet holes, and then flows out from the second air outlet holes 140 .

[0052] In this embodiment, the first air outlet and the second air outlet 140 are completely staggered, and the airflow passes through the first air outlet and then blows into the wind dispersing device 70. The airflow flows along the connecting hole 730, and flows out from the second air outlet 140 when it flows to the second air outlet 140. The strong wind is converted into soft wind by the completely staggered first air outlet and the second air outlet 140, so as to avoid the strong wind blown out from the first air outlet 30 directly blowing out from the second air outlet 140, and prevent the strong wind blown out by the air conditioner from directly blowing on the user, thereby improving the user experience.

[0053] In some embodiments of the present invention, the first air outlet hole and the second air outlet hole 140 are arranged alternately so that the airflow is changed in direction by the second plate 130 and the wind dispersion device 70 after entering the air guide gap 150 through the first air outlet hole, and then flows out from the second air outlet hole 140.

[0054] In this embodiment, the first air outlet and the second air outlet 140 are completely staggered, and the airflow passes through the first air outlet and blows to the inner surface of the second plate 130 and the wind dispersing device 70. The airflow flows along the inner surface of the second plate 130 and the connecting hole 730, and flows out from the second air outlet 140 when it flows to the second air outlet 140. The strong wind is converted into soft wind by the completely staggered first air outlet and the second air outlet 140, so as to avoid the strong wind blown out from the first air outlet 30 directly blowing out from the second air outlet 140, and prevent the strong wind blown out by the air conditioner from blowing directly to the user, thereby improving the user experience.

[0055] In some embodiments of the present invention, Figure 2 As shown, the end of the second air outlet 140 on the surface of the second plate 130 facing the first plate 110 is spaced from the wind dispersing device 70. The end of the second air outlet 140 on the surface of the second plate 130 facing the first plate 110 deviates from the air outlet direction of the connecting hole 730.

[0056] In this embodiment, the wind dispersing device 70 is spaced apart from the second air outlet 140, and the air outlet direction of the connecting hole 730 deviates from the second air outlet 140. When the airflow flows outward from the wind dispersing device 70 through the connecting hole 730, it flows in a direction deviating from the second air outlet 140, and the airflow is further dispersed in the air guide interval 150, and then flows out from the second air outlet 140. The air outlet direction of the connecting hole 730 deviates from the second air outlet 140, so that the airflow is further dispersed in the air guide interval 150, thereby improving the dispersion effect of the airflow, preventing the strong wind blown by the air conditioner from directly blowing the user, and thus improving the user experience.

[0057] In some embodiments of the present invention, the shape and size of the entrance of the internal space 720 are the same as the shape and size of the end of the first air outlet on the surface of the first plate body 110 facing the second plate body 130 .

[0058] In this embodiment, the shape and size of the inlet of the internal space 720 are the same as those of the first air outlet, so that more air flows enter the internal space 720 for dispersion, thereby improving the wind dispersion effect of the wind dispersion device 70 and further improving the user experience.

[0059] In other embodiments of the present invention, the size of the inlet of the internal space 720 can be adjusted according to actual needs. The smaller the inlet of the internal space 720, the less airflow enters the wind dispersing device 70, and the greater the wind speed blown out from the wind guide device 10. Conversely, the larger the inlet of the internal space 720, the more airflow enters the wind dispersing device 70, and the smaller the wind speed blown out from the wind guide device 10.

[0060] In some embodiments of the present invention, Figure 4 As shown, the wind dispersing device 70 includes a wind dispersing protrusion, which includes a wind dispersing portion 741 with a small head end and a large bottom end, and the head end of the wind dispersing portion 741 faces the center of the end of the first air outlet on the surface of the first plate body 110 facing the second plate body 130.

[0061] In this embodiment, a wind dispersing protrusion is provided at the position of the second plate 130 facing the first air outlet. After the airflow is blown out from the first air outlet, it blows onto the wind dispersing protrusion, flows along the surface of the wind dispersing protrusion, and then blows out through the second air outlet 140, so as to realize the air outlet of the air conditioner without feeling. Through the wind dispersing protrusion, the airflow is diffused to the surrounding of the wind dispersing protrusion, so as to improve the dispersing effect of the strong wind, realize the air outlet of the air conditioner without feeling of wind, and thus improve the user experience.

[0062] In some embodiments of the present invention, Figure 3As shown, the first plate 110 is arranged in parallel with the second plate 130, and the wind dispersing device 70 is arranged on the surface of the second plate 130 facing the first plate 110. When the wind guiding device 10 guides wind, the first plate 110, the wind dispersing device 70 and the second plate 130 are arranged in sequence along the flow direction of the airflow.

[0063] In some embodiments of the present invention, the ratio between the maximum and minimum values ​​of the interval between the first plate 110 and the second plate 130 is between 1 and 1.2. The ratio between the maximum and minimum values ​​of the interval between the surface of the first plate 110 facing away from the second plate 130 and the surface of the second plate 130 facing away from the first plate 110 is between 1 and 1.2.

[0064] In some embodiments of the present invention, the angle between the axes of each two adjacent first air outlet holes is within 5°. The angle between the axes of each two adjacent first air outlet holes is within 5°. The angle between the axes of each adjacent first air outlet hole and the second air outlet hole 140 is within 5°.

[0065] In this embodiment, the angle between the axis of the first air outlet and the axis of the second air outlet 140 is small, which avoids the correspondence between the first air outlet and the second air outlet 140 so that the wind blown out of the first air outlet is directly blown out from the second air outlet 140, preventing strong wind from blowing directly on the user and improving the user experience.

[0066] Further, the axes of two adjacent first air outlet holes are parallel. The axes of two adjacent second air outlet holes 140 are parallel. The axes of the adjacent first air outlet holes and second air outlet holes 140 are parallel.

[0067] In some embodiments of the present invention, the area of ​​the second air outlet hole 140 is greater than the area of ​​the first air outlet hole, and the ratio of the area of ​​the second air outlet hole 140 to the area of ​​the first air outlet hole is between 1.2 and 1.5.

[0068] In this embodiment, after the airflow passes through the first air outlet, the wind speed is reduced after being dispersed by the air guide space 150. The area of ​​the second air outlet 140 is larger than the area of ​​the first air outlet, so that the airflow in the air guide space 150 flows out of the second air outlet 140 faster, reducing the loss of airflow, preventing the air volume and cooling capacity of the air conditioner from being greatly reduced, and thus improving the user experience.

[0069] In some embodiments of the present invention, Figure 3 As shown, a blocking structure 60 is disposed between the edge of the first plate body 110 and the edge of the second plate body 130 , and the blocking structure 60 is a flange formed on the edge of the first plate body 110 .

[0070] In this embodiment, a blocking structure 60 is provided between the edge of the first plate body 110 and the edge of the second plate body 130 to prevent the airflow after passing through the first air outlet from being blown out from the edge of the air guide spacer 150. The blocking structure 60 is a flange formed on the edge of the first plate body 110, which is easy to manufacture when producing the air guide device 10, thereby reducing the production cost of the air guide device 10.

[0071] The embodiment of the utility model further provides an air conditioner indoor unit 100 , comprising an air outlet 30 and an air guide device 10 according to any one of the above embodiments, wherein the air guide device 10 is disposed at the air outlet 30 .

[0072] In this embodiment, an air guide device 10 is installed at the air outlet 30 of the air conditioner indoor unit 100. When the air conditioner indoor unit 100 blows air outward, the air flow passes through the air guide device 10, and the air guide device 10 disperses the strong wind blown out by the air conditioner indoor unit 100, and the air flow blown into the room is soft wind. The air guide device 10 is used to achieve a windless feeling when the air conditioner indoor unit 100 blows out air, so as to prevent the strong wind blown out by the air conditioner from directly blowing on the user, thereby improving the user's experience.

[0073] In some embodiments of the present invention, Figure 3 As shown, the air-conditioning indoor unit 100 also includes a shell 20 and two sliding baffles 40. The shell 20 is vertically arranged, and two air outlets 30 extending in the vertical direction are arranged on the shell 20. There are two air guide devices 10, which are respectively arranged corresponding to the two air outlets 30, and each air guide device 10 is rotatably arranged. Each sliding baffle 40 is movably mounted on the shell 20 to move to a position of closing an air outlet 30 and a position of opening the air outlet 30. Each sliding baffle 40 is arranged on the outside of an air guide device 10. A accommodating space 50 is also defined in the shell 20, and the accommodating space 50 is arranged between the two air outlets 30. Each sliding baffle 40 can be moved into the accommodating space 50 to be in a position of opening the corresponding air outlet 30.

[0074] In this embodiment, an air guide device 10 and a sliding baffle 40 are provided at the air outlet 30 of the air conditioner indoor unit 100. The air guide device 10 can be rotatably arranged. When the air conditioner indoor unit 100 operates in the direct blowing prevention mode, the air guide device 10 rotates to the air outlet 30, and the direct blowing prevention function of the air conditioner indoor unit 100 is realized by using the air guide device 10. When the air conditioner indoor unit 100 operates in other modes, the air guide device 10 rotates to the position where the air outlet 30 is opened. Through the rotation of the air guide device 10, the air conditioner indoor unit 100 has a variety of air supply modes, further improving the user experience. The sliding baffle 40 can be slidably arranged. When the air conditioner indoor unit 100 is working, the sliding baffle 40 slides to the accommodation space to open the air outlet 30, and the internal space 720 of the air conditioner indoor unit 100 is reasonably used. When the air conditioner indoor unit 100 is closed, the sliding baffle 40 slides to the air outlet 30 to close the air outlet 30, so as to prevent dust from entering the interior of the air conditioner indoor unit 100.
