After the airflow is guided by the first wind guide tube 140 and the second wind guide tube 150, the airflow guides the air to both sides of the first plate body 110, avoiding the airflow from blowing directly to the user, thereby improving the user's experience. Moreover, when the airflow passes through the surface of the air inlet side of the first plate body 110 when blowing to the first plate body 110, the speed of the airflow is weakened, and the wind force of the blown airflow is weakened, thereby reducing the physical discomfort caused by the hard wind blowing directly to the user, and the user thus obtains a good user experience.

[0041] In some embodiments of the present invention, Figure 2As shown, the plurality of first air outlet holes 120 are arranged in a matrix, and the plurality of second air outlet holes 130 are disposed on one side of the plurality of first air outlet holes 120 , and the plurality of second air outlet holes 130 are arranged in a matrix. The number of the first air outlet holes 120 is greater than the number of the second air outlet holes 130 .

[0042] In this embodiment, the first air outlet holes 120 and the second air outlet holes 130 are arranged in a matrix, so that the first air guide tubes 140 and the second air guide tubes 150 are arranged in a matrix, so that the air guiding device 10 guides the air more evenly, thereby improving the air guiding effect of the air guiding device 10. In addition, the first air outlet holes 120 and the second air outlet holes 130 arranged in a matrix make the appearance of the first plate body 110 more neat and beautiful, and it is more convenient to manufacture the air guiding device 10.

[0043] In some embodiments of the present invention, Figure 2 As shown, the plurality of first air outlet holes 120 are arranged in at least two rows along the width direction of the first plate body 110. The plurality of second air outlet holes 130 are arranged in at least one row along the width direction of the first plate body 110. The number of the first air outlet holes 120 in each row is equal to the number of the second air outlet holes 130 in each row.

[0044] In this embodiment, the number of the first air outlet holes 120 in each row is the same as the number of the second air outlet holes 130 in each row, so that the air guiding device 10 guides the air more evenly, thereby improving the air guiding effect of the air guiding device 10 and improving the user experience.

[0045] In some embodiments of the utility model, the axis of each first air outlet hole 120 is intersected with the axis of the corresponding first air guide tube 140, and the axis of each second air outlet hole 130 is intersected with the axis of the corresponding second air guide tube 150. The angle between each first air outlet hole 120 and the first plate body 110 is 80° to 90°, and the angle between each second air outlet hole 130 and the first plate body 110 is 80° to 90°. The angle between the axis of the first air guide tube 140 and the air outlet side surface of the first plate body 110 is 40° to 60°, and the angle between the axis of the second air guide tube 150 and the air outlet side surface of the first plate body 110 is 40° to 60°.

[0046] In some embodiments of the present invention, each first air outlet hole 120 is a tapered hole that gradually shrinks along the airflow direction. Each second air outlet hole 130 is a tapered hole that gradually shrinks along the airflow direction.

[0047] In this embodiment, the air inlet side of the first air outlet 120 and the second air outlet 130 is larger, so that more airflow enters the first air outlet 120 and the second air outlet 130 for guidance, thereby reducing the loss of airflow.

[0048] In some embodiments of the present invention, Figure 3 As shown, the air guide device 10 further includes a second plate 160, which is disposed on the air inlet side of the first plate 110, and the second plate 160 is spaced apart from the first plate 110 to form an air guide gap 180. A plurality of third air outlet holes are disposed on the second plate 160, so that the airflow passes through the third air outlet holes and the air guide gap 180 in sequence and then enters the first air outlet hole 120 and the second air outlet hole 130.

[0049] In this embodiment, the air guide device 10 includes a first plate body 110 and a second plate body 160, and an air guide interval 180 is provided between the first plate body 110 and the second plate body 160. The first plate body 110 is provided with a first air outlet hole 120 and a second air outlet hole 130, and the second plate body 160 is provided with a third air outlet hole. When the air guide device 10 guides air, the airflow is blown out from the third air outlet hole, dispersed in the air guide interval 180, and then flows out through the first air outlet hole 120 and the second air outlet hole 130, and is guided into the room through the first air guide tube 140 and the second air guide tube 150. The air guide device 10 with double-layer micropores converts strong wind into soft wind, achieves a windless feeling, and prevents the strong wind blown by the air conditioner from blowing directly on the user, thereby improving the user's experience.

[0050] In some embodiments of the present invention, the first air outlet 120 and the second air outlet 130 are arranged alternately with the third air outlet so that the airflow is changed in direction by the first plate 110 after entering the air guide gap 180 through the third air outlet, and then flows out from the first air outlet 120 and the second air outlet 130.

[0051] In this embodiment, the first air outlet 120 and the second air outlet 130 are staggered with the third air outlet, and the airflow passes through the third air outlet and blows into the air guide space 180, and is dispersed in the air guide space 180 and then blown out through the first air outlet 120 and the second air outlet 130. This arrangement converts strong wind into soft wind, avoids the strong wind blown out from the third air outlet directly from the first air outlet 120 and the second air outlet 130, and prevents the strong wind blown out by the air conditioner from directly blowing on the user, thereby improving the user experience.

[0052] In some embodiments of the present invention, the ratio between the maximum and minimum values ​​of the interval between the second plate 160 and the first plate 110 is between 1 and 1.2. The ratio between the maximum and minimum values ​​of the interval between the surface of the second plate 160 facing away from the first plate 110 and the surface of the first plate 110 facing away from the second plate 160 is between 1 and 1.2.

[0053] In other embodiments of the present invention, the areas of the first air outlet 120 and the second air outlet 130 are greater than the area of ​​the third air outlet, and the ratio of the areas of the first air outlet 120 and the second air outlet 130 to the area of ​​the third air outlet is between 1.2 and 1.5.

[0054] In this embodiment, after the airflow passes through the third air outlet, the wind speed is reduced after being dispersed by the air guide interval 180. The area of ​​the first air outlet 120 and the second air outlet 130 is larger than the area of ​​the third air outlet, so that the airflow in the air guide interval 180 flows out of the first air outlet 120 and the second air outlet 130 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.

[0055] In some embodiments of the present invention, Figure 3 As shown, a blocking structure 60 is disposed between the edge of the second plate body 160 and the edge of the first plate body 110 , and the blocking structure 60 is a flange formed on the edge of the second plate body 160 .

[0056] 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 160 to prevent the airflow after passing through the third air outlet from being blown out from the edge of the air guide space 180. The blocking structure 60 is a flange formed on the edge of the second plate body 160, which is easy to manufacture when producing the air guide device 10, thereby reducing the production cost of the air guide device 10.

[0057] The embodiment of the utility model further provides an air conditioner indoor unit 100, comprising an air outlet duct having an air outlet 30 and an air guide device 10 in any one of the above embodiments, wherein the air guide device 10 is disposed at the air outlet 30 or in the air outlet duct.

[0058] In this embodiment, the wind guide device 10 guides the wind to both sides of the first plate body 110, and the airflow on both sides blows to the wall surface of the air duct, and the wind force is weakened before blowing out. The airflow blown into the room is a gentle soft wind, which improves the user experience. Moreover, when the airflow blows to the first plate body 110 and passes through the surface of the air inlet side of the first plate body 110, the speed of the airflow is weakened, and the wind force of the blown airflow is weakened, reducing the physical discomfort caused by the hard wind blowing directly to the user, so that the user can get a good user experience.

[0059] In some embodiments of the present invention, Figure 3 As shown, the air conditioner indoor unit 100 further includes a housing 20, which is vertically arranged, has two air outlet ducts in the housing 20, and is provided with two air outlets 30 extending in the vertical direction on the housing 20. There are two air guide devices 10, which are respectively arranged in the two air outlet ducts, and each air guide device 10 is rotatably arranged. The first air guide cylinder 140 faces the outer duct wall of the corresponding air outlet duct.

[0060] In this embodiment, the air guide device 10 is rotatable. 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 air flow is blown from the first air guide tube 140 and the second air guide tube 150 to both sides of the air guide device 10, thereby realizing the direct blowing prevention function of the air conditioner indoor unit 100. When the air guide device 10 opens the air outlet 30, part of the air flow enters the first air guide hole and the second air guide hole, and is blown out from the first air guide tube 140 and the second air guide tube 150. The air flow blown out of the first air guide tube 140 and the second air guide tube 150 collides with the air flow blown out of the two sides of the first plate body 110, thereby reducing the speed of the air flow, blowing soft and gentle wind into the room, and improving the user experience.

[0061] In some embodiments of the present invention, Figure 3 As shown, the air conditioner indoor unit 100 further includes two sliding baffles 40. Each sliding baffle 40 is movably mounted on the housing 20 to move to a position of closing one air outlet 30 and a position of opening the air outlet 30. Each sliding baffle 40 is arranged outside an air guide device 10. The housing 20 further defines a housing space 50, which is arranged between the two air outlets 30, and each sliding baffle 40 can be moved into the housing space 50 to be in a position of opening the corresponding air outlet 30.

[0062] In this embodiment, the sliding baffle 40 is 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, so as to reasonably utilize the internal space of the air conditioner indoor unit 100. 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.

[0063] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
