For example, a connecting shaft structure is arranged on the panel, and a shaft hole structure is arranged on the shell, or a shaft hole structure is arranged on the panel, and a connecting shaft structure is arranged on the shell. To connect the panel with the housing.

In order to conveniently maintain the interior of the air conditioner, the panel is usually required to be opened, and in the process of disassembly, under the condition that the opening angle of the panel is small, maintenance is inconvenient; however, when a force is applied to the panel, the position where the panel is connected to the housing is relatively fragile, and the connection between the panel and the housing is easily damaged.

Referring to fig. 1 to 4, an embodiment of the present disclosure provides an air conditioning indoor unit, including a casing 10 and a panel 20. Wherein, the housing 10 is provided with a track groove 30, one end of the track groove 30 is closed, and the other end of the track groove 30 is open; a panel 20 on which a connecting assembly 40 is disposed, the connecting assembly 40 including a connecting shaft 41 movably disposed in the rail groove 30 to rotate the panel 20 on the housing 10; when the panel 20 is rotated to a predetermined angle on the housing 10, the connecting shaft 41 slides from the closed end of the track groove 30 to the open end of the track groove 30.

A track groove 30 is arranged on the shell 10, a connecting assembly 40 is arranged on the panel 20, and a connecting shaft 41 of the connecting assembly 40 is movably arranged in the track groove 30, so that the panel 20 can rotate on the shell; meanwhile, one end of the track groove 30 is closed, and the other end is open, and under the condition that the panel 10 normally rotates, the connecting shaft 41 only rotates at the closed end of the track groove 30; when a force is applied after the panel 20 is opened to the maximum angle, the connection shaft 20 slides toward the open end of the rail groove 30 and is separated from the opening of the rail groove 30. Thus, even when the panel 20 is violently attached and detached, the joint between the panel 20 and the casing 10 is prevented from being broken, and the panel 20 is protected.

In the embodiment of the present disclosure, the casing 10 of the air conditioner is used for mounting components such as a heat exchanger, a blower, a fan, and the like, and the air outlet is located below the casing 10. A side plate is provided above the housing 10, and a rail groove 30 is opened in the side plate, and the rail groove 30 is used to connect to the panel 20. Alternatively, in order to secure the stability of the panel 20 to which it can be connected, rail grooves 30 are provided at both sides above the housing 10.

In the embodiment of the present disclosure, as shown in fig. 3, one end of the track groove 30 is a closed structure, and the other end of the track groove 30 is an open structure; that is, the closed structure of the track groove 30 is the inside of the case 10, and the open structure of the track groove 30 is the outside of the case 10.

In the embodiment of the present disclosure, the panel 20 is provided with the connecting assembly 40, the connecting assembly 40 includes a connecting shaft 41 movably disposed in the track groove 30, and when the panel 20 rotates on the housing 10, the connecting shaft 41 rotates on the closed side of the track groove 30; when the panel 20 is rotated to a predetermined angle on the housing 10, the connecting shaft 41 slides from the closed end of the track groove 30 to the open end of the track groove 30. So that the connecting shaft 41 is disengaged from the housing 10, preventing further breakage of the connecting shaft 41.

Alternatively, the panel 20 is rotated on the housing 10 to a set angle, which is the maximum rotation angle of the panel on the housing 10. For example, when the panel 20 is opened and the panel 20 is rotated by 60 °, the side edge or the side surface of the panel 20 contacts the housing 10, and the housing 10 defines the rotation angle of the panel 20, so that a larger rotation angle cannot be performed. When a greater force is applied to rotate the panel 20 again, a great force is applied to the joint of the panel 20 and the housing 10, so that the joint of the panel 20 is forced to move, and the connecting member of the panel 20 is broken because the connecting member of the existing panel 20 cannot be displaced in the axial hole of the housing 10

Alternatively, since the track groove 30 is provided on the housing 10, and one end of the track groove 30 is an open structure, when a large force is applied to the joint of the panel 20 and the housing 10 to force the joint of the panel 20 to move, the connecting shaft 41 of the panel 20 may move in the track groove 30, thereby preventing the connecting shaft 41 on the panel 20 from being broken.

On the basis, when the panel 20 is rotated on the housing 10 beyond the set angle, the connecting shaft 41 can also slide out of the sliding portion 32.

In some alternative embodiments, the rotational position of the panel 20 on the housing 10 includes a first position, a second position, a third position, and a fourth position. Wherein, the first position is that the panel 20 is normally buckled on the shell 10; the second position is the first angle of rotation of the panel 20, and the connecting shaft 41 does not leave the limiting part 31; the third position is the second angle of rotation of the panel 20, and the connecting shaft 41 leaves the stopper 31 and enters the sliding portion 32; the fourth position is a third angle of rotation of the panel 20, and the link shaft 41 is separated from the slide 32. Here, the first angle is smaller than the second angle, which is smaller than the third angle.

As shown in fig. 7, in some embodiments, the open side of the position-limiting portion 31 has a first position-limiting convex edge 311 and a second position-limiting convex edge 312 to limit the connecting shaft 41 to be rotatably disposed in the position-limiting portion 31. When the panel 20 is rotated on the housing 10 to reach a set angle, the connecting shaft 41 is prevented from slipping out of the stopper portion 31.
