DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 , Figure 2 As shown, the present invention provides an air conditioner indoor unit, which includes a panel 1, a middle frame 2, an air outlet frame 3, a cover plate 4, a base assembly 5, an air guide plate 6, an evaporator 7 and other components. As an example of the present invention, the base assembly 5 is fixed to the wall through a wall-mounted plate, and the base assembly 5 is connected to the middle frame 2 and together forms a receiving chamber for receiving components such as the evaporator 7 and axial flow blades. An air inlet grille is provided on the top of the middle frame 2; preferably, the middle frame 2 and the air inlet grille are integrally formed. A panel 1 is provided on the outer surface of the middle frame 2, and the panel 1 and the middle frame 2 are connected by hinges or snap-fits. As an example of the present invention, the panel 1 is snap-fitted to the middle frame 2. This arrangement facilitates the removal of the panel 1 from the middle frame 2, and facilitates cleaning and maintenance of the interior of the air conditioner. The air guide plate 6 is located at the lower end of the middle frame 2 and is used to adjust the wind direction of the outlet air flow. The air guide plate 6, the panel 1, the middle frame 2, the air inlet grille, and the air outlet frame 3 together constitute the outer shell of the indoor unit. Since the above structures and assembly relationships are prior art, they will not be described in detail here.

[0031] like Figure 3 As shown, the lower end of the middle frame 2 is provided with an air outlet 35, and the air outlet frame 3 is arranged on the air outlet 35. The air outlet frame 3 includes a first end and a second end opposite to the first end; the first end is hingedly connected to the middle frame 2, and the second end is connected to the middle frame 2 by screwing or clamping. During maintenance, as long as the second end of the air outlet frame 3 is disassembled from the middle frame 2, and then the air outlet frame 3 is rotated in the horizontal direction, the air outlet frame 3 can be opened to expose the parts inside the air conditioner, so that it is convenient for workers to observe the internal conditions of the air conditioner or repair some parts. After the maintenance is completed, the air outlet frame 3 is turned back to its original position, so that the second end of the air outlet frame 3 is connected to the middle frame 2, so that the air outlet frame 3 is fixed again. This design greatly reduces the difficulty of high-altitude operations.

[0032] The air outlet frame 3 rotates with the first end as the axis to open or close the air outlet frame 3. This setting can quickly open the air outlet frame 3, which is convenient for inspecting the interior of the air conditioner indoor unit; at the same time, the air outlet frame 3 is not completely separated from the middle frame 2, which is more labor-saving, avoids carrying, and is convenient for maintenance personnel to operate.

This setting can realize the upside down or left-right flipping of the air outlet frame 3, and it can be set as needed to meet the needs of different working conditions, and has a wide range of applications. Preferably, the first end is the left end of the air outlet frame 3. After the air outlet frame 3 is opened, it rotates 180° with the first end as the axis under the action of its own gravity to open, thereby avoiding the air outlet 35, so that maintenance personnel can disassemble and repair the interior of the air conditioner from the position of the air outlet 35.

[0033] like Figure 3 , Figure 4 As shown, as an example of the present invention, a rotating assembly 32 is provided on the first end of the air outlet frame 3, and a shaft seat 22 is provided on the middle frame 2 corresponding to the position of the rotating assembly 32, and the rotating assembly 32 is rotatably connected to the shaft seat 22. This setting can realize the rotation connection between the air outlet frame 3 and the middle frame 2, and has a simple structure, is easy to machine, and has a wide range of applications. Preferably, the rotating assembly 32 is arranged at the middle position of the two ends of the air outlet frame 3 at its rotation axis to ensure that the air outlet frames 3 on both sides of the connection remain balanced during the flipping and opening process. As another example of the present invention, there are 3 rotating assemblies 32, and they are distributed at equal intervals along the rotation axis of the upper end of the air outlet frame 3. After opening the air outlet frame 3, its own gravity acts on the rotating assembly 32. This setting can make the rotating assembly 32 evenly stressed, ensuring the stability of the rotation connection between the air outlet frame 3 and the middle frame 2; at the same time, this setting can make the appearance of the air outlet frame 3 more beautiful and improve user satisfaction. As an example of the present invention, the rotating assembly 32 includes a connecting plate 33 and a rotating shaft 34. One side of the connecting plate 33 is connected to the air outlet frame 3, and the other side of the connecting plate 33 is connected to the rotating shaft 34. The rotating shaft 34 is inserted into the shaft seat 22. This setting further defines the rotating assembly 32 as a connecting plate 33 and a rotating shaft 34, so that the structure of the rotating assembly 32 is simple, the production cost is low, and the market competitiveness of the air conditioner is improved.

[0034] like Figure 3 , Figure 5As shown, the second end of the air outlet frame 3 is provided with one or more connecting members, and the middle frame 2 is provided with a limiting member at a position corresponding to the connecting member; during assembly, the connecting member and the limiting member are limitedly assembled. This setting can realize the fixed assembly between the second end of the air outlet frame 3 and the middle frame 2; at the same time, the number of connecting members can be set as needed to have both the tightness and convenience of the connection between the air outlet frame 3 and the middle frame 2. As an example of the present invention, the connecting member is made of iron material, and the limiting member is a magnet block, which is fixed by the magnetic force between the connecting member and the limiting member. As another example of the present invention, the connecting member is a buckle 31, and there are 2 buckles 31, and the limiting member is a slot 21, and the buckle 31 is assembled with the slot 21. The buckle 31 can also be provided on the middle frame 2, and the slot 21 is provided on the air outlet frame 3. This setting defines the second end of the air outlet frame 3 and the middle frame 2 as a buckle / slot structure, which is simple in structure and easy to produce and process. Preferably, the air outlet frame 3 and the buckle 31 are an integrated structure, which is integrally formed during production, so that the assembly operation of the buckle 31 and the air outlet frame 3 can be omitted, thereby improving the assembly efficiency of the product. It should be noted that the matching structure between the second end of the air outlet frame 3 and the middle frame 2 is not limited to the slot 21 and the buckle 31, and other solutions, such as a jack and a plug-in column, can also be selected. The air outlet frame 3 can be opened by rotating the air outlet frame 3 with a certain force so that the buckle 31 is elastically deformed and disengaged from the slot 21. After rotating the air outlet frame 3, the air outlet 35 is exposed, which is convenient for cleaning and repairing the inside of the air conditioner; when installing, the air outlet frame 3 is turned back to its original position so that the buckle 31 and the slot 21 are automatically engaged, and the air outlet frame 3 can be closed.
