[0046] The present invention provides an air conditioner indoor unit. The indoor unit is the indoor portion of a split-type air conditioner and is used to condition the indoor air, such as for cooling / heating, dehumidifying, and introducing fresh air. The indoor unit can be a conventional floor-standing cabinet unit or a vertical wall-mounted unit.

[0047] Figure 1 is a schematic front view of an air conditioner indoor unit according to an embodiment of the present invention, with reference to Figures 2 to 7 An embodiment of the present invention provides an air conditioner indoor unit, comprising an air outlet 10, an air guide body 18, and an air guide device 12. The front side of the air outlet 10 has an air outlet 11 extending along the length direction of the air outlet 10. The air guide body 18 extends along the length direction of the air outlet 11, and the air guide body 18 is arranged on one side of the air outlet 11. The air guide body 18 is provided with a through air duct 13, and the inlet and outlet of the through air duct 13 both extend along the length direction of the air outlet 11. The inlet of the through air duct 13 is close to the air outlet 11, and the outlet of the through air duct 13 is located obliquely in front of the inlet of the through air duct 13. The air guide device 12 is arranged at the air outlet 11 to guide the outlet air in the width direction of the air outlet 11. The air guide device 12 can move to a position where part or all of the airflow from the air outlet 11 enters the inlet of the through air duct 13.

[0048] During operation, the airflow from the air outlet 11 is guided forward or to one side by the air guide 12. When the air guide 12 moves to a position where part or all of the airflow from the air outlet 11 enters the inlet of the through-air duct 13, part or all of the airflow from the air outlet enters the inlet of the through-air duct 13 on one side of the air outlet 11 and is blown out from the outlet obliquely in front, thereby expanding the air outlet angle of the air outlet portion 10 and meeting the user's demand for air outlet angle.

[0049] In some embodiments of the present invention, the inlet of the through air duct 13 may also face the air outlet.

[0050] In some embodiments of the present invention, the inlet of the through air duct 13 may also be located in front of the air outlet.

[0051] In some embodiments of the present invention, there are two air outlets 11, two air guides 18, and two air guide devices 12. These two air outlets 11, two air guides 18, and two air guide devices 12 are symmetrically arranged about a vertical reference plane. The air guide 18 is located on the side of the air outlet 11 away from the other air outlet 11. The symmetrical arrangement of the two air outlets 11, two air guides 18, and two air guide devices 12 further increases the air output volume, air output area, and air output angle. This symmetrical arrangement also makes the appearance of the air conditioner indoor unit more aesthetically pleasing to Chinese people.

[0052] In some embodiments of the present invention, Figure 1 As shown, the air outlet 10 is vertically arranged, and correspondingly, the two air outlets 11 are also vertically arranged.

[0053] In some embodiments of the present invention, Figure 1 As shown, the two air outlets 10 are spaced apart to form an air induction gap 20 between the two air outlets 10. When the two air outlets 11 simultaneously blow air forward or in front of each other, the negative pressure generated can drive the air in the air induction gap 20 to flow forward and mix with the airflow blown out from the two air outlets 11, making the temperature of the mixed airflow close to the room temperature and the temperature of the blown airflow gentle.

[0054] In some embodiments of the present invention, Figure 2 As shown, the air guide 18 is rotatably arranged around an axis extending along the length direction of the air outlet 11.

[0055] In some embodiments of the present invention, the edge of the air outlet 11 adjacent to the air guide 18 is a first edge. A second edge is provided on the surface of the air outlet portion 10. The second edge coincides with the first edge.

[0056] In other embodiments of the present invention, the second edge is parallel to and spaced apart from the first edge, and the portion of the surface of the air outlet portion 10 between the first and second edges constitutes an air duct extension surface. The air guide 18 includes a first air guide 181 and a second air guide 182 spaced apart. The first air guide 181 has a third edge and a fourth edge extending along the length of the air outlet portion 10, and the second air guide 182 has a fifth edge and a sixth edge extending along the length of the air outlet portion 10. The third and fifth edges form an inlet, and the fourth and sixth edges form an outlet. The air guide can rotate to a position where the third edge approaches or contacts the second edge, a position where the fourth edge approaches or contacts the second edge, or a position where the fifth edge approaches or contacts the second edge. In other words, the air guide can have at least three positions during rotation: one where the third edge substantially overlaps with the second edge or has a relatively small gap; one where the fourth edge substantially overlaps with the second edge or has a relatively small gap; and one where the fifth edge substantially overlaps with the second edge or has a relatively small gap. When the air guide body rotates to any of the three positions, it cooperates with the movable air guide device 12 so that the air conditioner indoor unit has multiple air outlet modes.

[0057] In some embodiments of the present invention, the air outlet 11 further has an eighth edge extending along the length direction of the air outlet portion 10, and the eighth edge is located obliquely behind the first edge. The second edge is located obliquely in front of the first edge.

[0058] In some embodiments of the present invention, the air guide device 12 includes at least one air guide plate. For example, the air guide device 12 includes one air guide plate. One end of the air guide plate is close to or connected to the eighth edge, and the other end of the air guide plate can move to the front side of the second edge and contact the air guide body. The air guide plate and the air guide body work together to enable the air conditioner indoor unit to have multiple air outlet modes. For example, Figure 3 As shown, the air guide plate extends in the front-to-back direction, and the air guide body rotates to a position where the third edge approaches or contacts the second edge. Part of the airflow blown out from the air outlet 11 is blown forward, driving the air in the air induction gap 20 to flow forward, while the other part of the airflow is blown out obliquely in front of the air outlet 10 through the through air duct. This air outlet mode is a wide-area uniform airflow mode. Figure 4 As shown, the air guide plate moves to contact the second air guide body 182, and the air guide body rotates to a position where the third edge is close to or contacts the second edge, and all the airflow blown out from the air outlet 11 passes through the through air duct and blows out obliquely to the front of the air outlet portion 10. This air outlet mode is a wide-angle air supply mode. Figure 5 As shown, the air guide plate extends in the front-to-back direction, and the air guide body rotates to a position where the fifth edge approaches or contacts the second edge, and all the airflow blown out from the air outlet 11 is blown forward, driving the air in the air induction gap 20 to flow forward. This air outlet mode is a converged uniform airflow mode. Figure 6As shown, the wind guide plate on the left side moves to contact with the corresponding second wind guide body 182, and the corresponding wind guide body rotates to a position where the third edge is close to or in contact with the second edge, and all the airflow blown out from the corresponding air outlet 11 passes through the through air duct and blows out to the oblique front of the corresponding air outlet 10. The wind guide plate on the right side is tilted to the left so that the end of the wind guide plate away from the eighth edge is in oblique front of the other end, and the corresponding wind guide body rotates to a position where the fourth edge is close to or in contact with the second edge. At this time, both air outlets 10 blow air to the left front, and drive the air in the air induced gap 20 to flow to the left front. This air outlet mode is a left-to-left uniform wind mode. Of course, there are also Figure 7 As shown, the right-hand uniform wind mode.

[0059] In some embodiments of the present invention, Figure 2 As shown, the surface of the air outlet portion 10 is provided with a receiving groove for mounting the air guide 18. The edge of the receiving groove adjacent to the air outlet 11 is the second edge. Another edge of the receiving groove, extending along the length of the air outlet 11, is the seventh edge. When the air guide 12 closes the air outlet 11, the first air guide 181 can be rotated to a position that closes the gap between the seventh edge and the air guide 12. In other words, the air guide can be rotated to a position that, together with the air guide 12, closes the air outlet 11. This arrangement gives the air conditioner indoor unit a neat appearance and prevents foreign matter from entering when the air conditioner is turned off.

[0060] In some embodiments of the present invention, the air duct extension surface is a circular arc surface that bulges forward of the air outlet 11. When the third edge is close to or in contact with the second edge, the sidewall of the first air guide body used to form the through-air duct is coplanar with the air duct extension surface, and the air guide plate of the air guide device 12 closest to the air guide body contacts the second air guide body 182. The coplanarity of the sidewall of the through-air duct close to the first air guide body with the air duct extension surface can reduce the resistance of the airflow entering the through-air duct.

[0061] In some embodiments of the present invention, the third and fourth edges are connected by a first arcuate surface to form a sidewall of the through-air duct. The first arcuate surface is convex and specifically protrudes toward the second air guide 182. The fifth and sixth edges are connected by a second arcuate surface to form another sidewall of the through-air duct. The second arcuate surface is concave.

[0062] In some embodiments of the present invention, the air guide is cylindrical. The third edge and the fourth edge are further connected by a third arc surface to form the outer surface of the first air guide 181. Preferably, the central angle corresponding to the outer surface of the first air guide 181 is 170° to 190°.

[0063] The fifth edge and the sixth edge are further connected by a fourth arc surface to form the outer surface of the second air guide 182. Preferably, the central angle corresponding to the outer surface of the second air guide 182 is 55° to 65°.

[0064] In some embodiments of the present invention, the cylinder is coaxial with the third arc surface and the fourth arc surface.

[0065] In some embodiments of the present invention, the first arc surface and the outer surface of the first air guide 181 are located on both sides of the axis of the cylinder.

[0066] The embodiment of the present invention further provides an air guide body, which is a cylinder and includes a first air guide body and a second air guide body spaced apart in the diameter direction of the cylinder, with a through air duct formed between the first air guide body and the second air guide body.

[0067] In some embodiments of the present invention, the side wall of the through air duct on the first air guide is a first arc surface, and the side wall of the through air duct on the second air guide is a second arc surface.

[0068] In some embodiments of the present invention, the first arc surface and the outer surface of the first air guide are located on both sides of the axis of the cylinder.

[0069] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
