DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the prior art, in order to improve the user experience, the following are proposed: Figure 3 and Figure 4An air conditioner indoor unit with an upper air outlet 12 and a lower air outlet is shown, and the air conditioner indoor unit mainly includes a shell 2, an upper air guide plate 7, a lower air guide plate 10 and an air guide device 1, wherein the upper air guide plate 7 is rotatably connected to the outside of the upper air outlet 12, the air guide device 1 and the lower air guide plate 10 are rotatably connected to the outside of the lower air outlet, and the air conditioner indoor unit is provided with a cross-flow fan near the lower air outlet.

[0030] When the user selects the lower air outlet mode, it is only necessary to rotate the lower air guide plate 10. When the user selects the upper air outlet mode, it is necessary to rotate the upper air guide plate 7 while driving the air guide device 1 to move away from the shell 2, so that the air guide device 1, the lower air guide plate 10 and the shell 2 form an upper air outlet cavity, so that the airflow passes through the upper air outlet cavity and is discharged from the upper air outlet 12 formed between the upper wall of the air guide device 1 and the shell 2.

[0031] Since the two ends of the air guide device 1 are respectively connected to the two side end plates 3 of the air conditioner, preferably, they are movably connected through a crankshaft connecting rod mechanism; at the same time, in order to facilitate the movement of the air guide device 1, such as Figure 4 As shown, the direction of the arrow in the figure is the direction of the airflow returning to the inside of the shell 2, wherein the airflow includes cold air or hot air. The air-conditioning indoor unit is provided with a gap 11 between the side end plate 3 and the shell 2. However, when the gap 11 is in the upper air outlet mode, part of the airflow will flow back to the inside of the shell 2 through the gap 11 under the action of pressure, thereby reducing the air outlet volume of the upper air outlet 12 and affecting the working efficiency of the air conditioner.

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in the first aspect, the present application provides an air guide device 1, preferably, the air guide device 1 is a moving air guide plate, and is used in an air-conditioning indoor unit, the air guide device 1 is movably connected to the air-conditioning indoor unit, wherein the air guide device 1 can reciprocate towards or away from the shell 2 along a direction perpendicular to the placement direction of the air-conditioning indoor unit; there is a gap 11 between the side end plate 3 of the air-conditioning indoor unit and the shell 2, the air guide device 1 has two ends, the two ends are respectively movably connected in the gap 11, and two seals 4 are respectively provided on the two ends, the two seals 4 are used to extend into the gap 11 respectively to block the airflow entering the gap 11; in the present embodiment, the two seals 4 are connected to the upper wall surface of the end of the air guide device 1, preferably, the seal 4 is of a planar type.

[0034] The present solution adopts a method of setting a seal 4 on the air guide device 1, so that when in the upper air outlet mode, the air conditioner can automatically seal the gap 11 between the side end plate 3 and the shell 2 during operation, thereby effectively preventing part of the air flow from flowing back to the inside of the shell 2 through the gap 11 under the action of wind pressure, thereby improving the sealing performance and ensuring the air outlet volume of the upper air outlet 12, while reducing costs without the need for additional parts.

[0035] According to one embodiment of the present invention, in order to ensure the sealing performance, as Figure 6 As shown, the shape of the seal 4 is adapted to the gap 11. Preferably, the seal 4 is set to a hook-shaped structure, and the seal 4 includes: an integrally formed arc-shaped transition section 5 and a pointed protrusion section 6; and the seal 4 reciprocates in a direction close to or away from the shell 2 driven by the air guide device 1 to block the gap 11. Specifically, when the lower air outlet mode is switched to the upper air outlet mode, the air guide device 1 will move away from the shell 2. At the same time, the seal 4 will be driven by the air guide device 1 to move in a direction away from the shell 2 to extend from the shell 2 to block the gap 11. On the contrary, when the upper air outlet mode is switched to the lower air outlet mode, the air guide device 1 will move close to the shell 2. At the same time, the seal 4 will be driven by the air guide device 1 to retract into the shell 2 in a direction close to the shell 2, thereby avoiding the seal 4 from affecting the cooperation between the upper air guide plate 7 and the upper air outlet 12, and finally ensuring the sealing performance of the air conditioner.

[0036] According to one embodiment of the present invention, Figure 6 As shown, in order to avoid a sealing gap between the seal 4 and the gap 11 when the seal 4 moves with the air guide device 1, thereby affecting the sealing performance due to the sealing gap, the length (L) of the seal 4 is greater than the length of the gap 11.

[0037] According to one embodiment of the present invention, Figure 2 As shown, in order to ensure the synchronization between the seal 4 and the air guide device 1 , the edge line of the seal 4 close to the shell 2 is flush with the edge line of the air guide device 1 close to the shell 2 .

[0038] According to one embodiment of the present invention, Figure 1 As shown, the width (W) of the seal 4 is smaller than the depth of the gap 11. When switching from the upper air outlet mode to the lower air outlet mode, the air guide device 1 will move closer to the shell 2, and the upper air guide plate 7 will rotate toward the upper air outlet 12 to block the air outlet. This design is to avoid the seal 4 being too wide, resulting in part of the seal 4 remaining outside the gap 11 when following the movement of the air guide device 1, thereby affecting the coordination between the upper air guide plate 7 and the upper air outlet 12, and ultimately ensuring the sealing performance of the air conditioner.

[0039] According to one embodiment of the present invention, Figure 2 As shown, in order to simplify the manufacturing process, the sealing member 4 and the air guiding device 1 are integrally formed.

[0040] According to one embodiment of the present invention, Figure 2 As shown, in order to ensure the sealing performance of the upper air guide plate 7 and the upper air outlet 12, the area enclosed by the two seals 4 and the air guide device 1 is aligned with the upper air guide plate 7 of the air conditioner, and the shape is adapted to the shape of the lower edge of the upper air guide plate 7 of the air conditioner.

[0041] According to one embodiment of the present invention, Figure 2 As shown, the air guide device 1 includes: a front panel 8 and supporting side panels 9 arranged on both sides of the front panel 8, two seals 4 are fixedly connected to the top of the supporting side panels 9, and an arc structure 13 extends from the other end of the supporting side panels 9, and the arc structure 13 is used to seal the lower air guide plate 10.

[0042] like Figure 5 and Figure 6 As shown, in a second aspect, the present application provides an air-conditioning indoor unit, comprising an air guide device 1 of any one of the aforementioned items.

[0043] According to one embodiment of the present invention, the air-conditioning indoor unit has an upper air outlet 12 and a lower air outlet, and the air-conditioning indoor unit includes: a shell 2, an upper air guide plate 7 rotatably connected to the upper air outlet 12, and a lower air guide plate 10 rotatably connected to the lower air outlet, the air guide device 1 moves away from the shell 2 so that the air guide device 1, the lower air guide plate 10 and the shell 2 form an upper air outlet cavity, so that the area formed by the upper wall surface of the air guide device 1 and the shell 2 is the upper air outlet 12.

[0044] In a third aspect, the present application provides an air conditioner, comprising the aforementioned air conditioner indoor unit.

[0045] The specific working process is as follows:

[0046] When the lower air outlet mode is switched to the upper air outlet mode, the air guide device 1 will move away from the shell 2. At the same time, the seal 4 will be driven by the air guide device 1 to move in the direction away from the shell 2, and extend from the shell 2 to seal the gap 11. On the contrary, when the upper air outlet mode is switched to the lower air outlet mode, the air guide device 1 will move closer to the shell 2. At the same time, the seal 4 will be driven by the air guide device 1 to retract into the shell 2 in the direction close to the shell 2, thereby avoiding the seal 4 from affecting the coordination between the upper air guide plate 7 and the upper air outlet 12, and finally ensuring the sealing performance of the air conditioner.
