[0031] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0032] In order to solve the problem that when the existing air conditioner indoor unit achieves the purpose of preventing direct blowing by installing an air guide plate with multiple air holes, the air supply distance of the air conditioner indoor unit is affected, resulting in poor balance of cooling effect and cooling speed in various areas of the room, this embodiment provides an air conditioner indoor unit.

[0033] like Figures 1 to 6As shown, the air conditioner indoor unit provided in this embodiment includes an indoor unit body 1, an air outlet 11 is provided on the indoor unit body 1, and a first air guide plate 12 for opening and closing the air outlet 11 is installed on the indoor unit body 1; it also includes a second air guide plate 2, and a wind flow gap is provided on the second air guide plate 2; the second air guide plate 2 is rotatably / slidably connected to the outside of the indoor unit body 1, and the second air guide plate 2 is configured to be able to rotate / slide to the air outlet 11 and avoid the air outlet 11.

[0034] For example, Figure 1 and Figure 2 The illustrated air conditioner indoor unit is a wall-mounted unit. An air outlet 11 is located on the underside of the indoor unit body 1. A rotating shaft 14 is provided on each end cap 13 of the indoor unit body 1. A second air deflector 2 has connecting ends 23 at each end that are rotatably connected to the rotating shaft 14. Thus, the second air deflector 2 can rotate around the rotating shaft 14 on the end cap 13 to move toward or away from the air outlet 11.

[0035] It can be understood that although the drawings of this embodiment illustrate the example of the second air guide plate 2 being rotatably connected to the end covers 13 on both sides of the indoor unit body 1 of the wall-mounted air conditioner indoor unit, the type of air conditioner indoor unit is not fixed, and without departing from the principles of the present invention, those skilled in the art can also adjust or select the specific connection method between the second air guide plate 2 and the indoor unit body 1 according to the type of the air conditioner indoor unit and specific needs, so as to adapt to specific application scenarios.

[0036] For example, the air conditioner indoor unit may be a cabinet-type indoor unit, and a slide rail may be provided on the housing of the indoor unit body 1 of the cabinet-type indoor unit, with the second air guide plate 2 being slidably provided on the slide rail. In this way, the second air guide plate 2 can slide to the air outlet 11 or avoid the air outlet 11 by sliding on the slide rail.

[0037] In the air conditioner indoor unit provided in this embodiment, the second air guide plate 2 is rotatably / slidably connected to the outside of the indoor unit body 1, and the second air guide plate 2 is configured to be rotatable / slidable to and away from the air outlet 11. In this way, when the air conditioner indoor unit is in cooling operation, when it is necessary to prevent cold air from blowing directly on the human body, the second air guide plate 2 can be rotated / slid to the air outlet 11. When the cold air hits the second air guide plate 2, it will be dispersed, making the cold air softer. At the same time, some of the cold air can be blown out over long distances along the airflow gaps on the second air guide plate 2. Therefore, the cold air blown out by the air conditioner indoor unit provided in this embodiment is not only soft but also has a long-distance cooling effect and speed.

[0038] In addition, in an air conditioner indoor unit provided in this embodiment, when the air conditioner indoor unit is a wall-mounted air conditioner indoor unit and the second air guide plate 2 is rotated to the bottom of the indoor unit body 1, when the air outlet 11 of the indoor unit body 1 blows out cold air, a negative pressure area will be formed between the indoor unit body 1 and the second air guide plate 2, so that part of the indoor air can pass through the negative pressure area from the rear side of the indoor unit body 1 and be mixed with the cold air blown out from the air outlet 11 and then blown out, thereby making the human body feel softer when the air conditioner indoor unit blows out cold air, and can promote the mixing efficiency of cold air and hot air.

[0039] As a preferred implementation of the air conditioner indoor unit provided in this embodiment, Figure 3 and Figure 4 As shown, a first positioning portion is provided on the rotating shaft 14 on at least one end cover 13, and a second positioning portion cooperating with the first positioning portion is provided on at least one connecting end 23; when the second air guide plate 2 rotates to the air outlet 11, the first positioning portion cooperates with the second positioning portion to fix the second air guide plate 2 at the air outlet 11.

[0040] It can be understood that it is only necessary to set a first positioning portion on one end cover 13 of the indoor unit body 1 and a second positioning portion on a connecting end 23 that matches it to achieve the fixation of the second air guide plate 2, but the first positioning portion and the second positioning portion can also be respectively set on the end covers 13 on both sides and the two connecting ends 23 of the second air guide plate 2.

[0041] For example, Figure 3 and Figure 4 As shown, an annular groove 141 can be provided on the outer wall of the rotating shaft 14; the connecting end 23 is sleeved onto the rotating shaft 14, and the opening of the connecting end 23 is provided with a claw 231 that extends into the annular groove 141. In this way, when the second air deflector 2 rotates about the rotating shaft 14, the claw 231 engages in the annular groove 141 of the rotating shaft 14, maintaining a tight fit between the connecting end 23 and the rotating shaft 14 during the rotation of the second air deflector 2. Furthermore, the rotating shaft 14 and the connecting end 23 can also achieve relative rotation by being connected to the inner and outer rings of a bearing, respectively.

[0042] Furthermore, the first positioning portion can be a slot 142 provided on a side wall of the annular groove 141 away from the indoor unit body 1; the second positioning portion is a claw 231. Thus, when the second air guide plate 2 rotates to the air outlet 11, the purpose of fixing the second air guide plate 2 at the air outlet 11 can be achieved through the cooperation between the claw 231 and the slot 142. In addition, multiple slots 142 can be provided on a side wall of the annular groove 141 away from the indoor unit body 1, and multiple claws 231 can be provided at the connecting end 23 of the second air guide plate 2. Figure 4 There are four claws 231 at the connection end 23 of the second air guide plate 2, correspondingly Figure 3 The rotating shaft 14 in the indoor unit is provided with four slots 142. In this way, the second air guide plate 2 can be fixed to different positions of the indoor unit body 1.

[0043] As a preferred embodiment of the air conditioner indoor unit provided in this embodiment, a compressed elastic member is provided between the rotating shaft 14 and the connecting end 23, and the elastic member is configured to expand and contract along the axis of the rotating shaft 14. Figure 3 and Figure 4 In the indoor unit of the air conditioner shown, the elastic member is a spring 143. It can be understood that the elastic member can also be an elastic rope.

[0044] In this way, when the claw 231 of the connecting end 23 rotates to the position of the groove 142 in the annular groove 141, the claw 231 can be pushed into the groove 142 under the elastic pressure of the elastic member; when a person applies pressure toward the indoor unit body 1 to the connecting end 23 by hand, the claw 231 withdraws from the groove 142 to the annular groove 141 and can continue to rotate around the annular groove 141. In this way, the second air guide plate 2 can be fixed at a certain position relative to the indoor unit body 1.

[0045] As a preferred embodiment of the air conditioner indoor unit provided in this embodiment, a fixing groove or fixing column 232 for fixing one end of the elastic member is provided on the rotating shaft 14; and / or a fixing groove or fixing column 232 for fixing the other end of the elastic member is provided on the connecting end 23. In this way, one end of the elastic member can be inserted into the fixing groove or sleeved on the fixing column 232 to fix or position the two ends of the elastic member, so that the elastic member can better achieve the effect of forming opposite elastic pressure between the opposite surfaces of the rotating shaft 14 and the connecting end 23. Figure 4 In the embodiment, a fixing column 232 is provided at the connecting end of the extension arm 22, and a hole for placing the spring 143 is provided in the fixing column 232. At the same time, a fixing column 232 can be provided on the rotating shaft of the indoor unit body 1, and one end of the spring 143 can be directly sleeved on the fixing column.

[0046] As a preferred implementation of the air conditioner indoor unit provided in this embodiment, Figure 1 、 Figure 2 and Figure 4As shown, the second air guide plate 2 includes a grille plate 21 and extension arms 22 connected to both ends of the grille plate 21. The extension arms 22 are configured to extend from the grille plate 21 toward the end cover 13, and the extension arms 22 are provided with a connecting end 23 on the side facing the end cover 13. The grille holes 211 in the grille plate 21 form airflow gaps. The length of the extension arms 22 can be designed to accommodate indoor unit bodies 1 of different sizes and facilitate the design of the distance between the grille plate 21 on the second air guide plate 2 and the air outlet 11 when the grille plate 21 is fixed to the air outlet 11.

[0047] As a preferred implementation of the air conditioner indoor unit provided in this embodiment, Figure 5 and Figure 6 As shown, the axial direction of the grid holes 211 is tilted relative to the grid plate 21. Figure 6 As shown in the figure, the angle between the grid hole 211 and the grid plate 21 is β. In this way, when the indoor unit of the air conditioner is cooling, it can avoid or reduce the formation of condensed water after the cold air blown out of the indoor unit body 1 and the indoor hot air meet at the grid hole 211 of the grid plate 21, thereby achieving the technical effect of preventing both cold wind and condensation.

[0048] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0049] Furthermore, those skilled in the art will appreciate that although some embodiments described herein include certain features that are included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of the present invention and to form different embodiments. For example, in the claims of the present invention, any of the claimed embodiments may be used in any combination.

[0050] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
