As shown in fig. 3 and 4, the first limiting member 40 includes: limiting plate 41, spacing muscle 42 and strengthening rib 43, limiting plate 41 is on a parallel with support piece setting, and spacing muscle 42 is arranged in one side of limiting plate 41 towards support piece, and spacing muscle 42 links to each other and is located the left side of limiting plate 41 with limiting plate 41 promptly, and spacing muscle 42 includes two, and interval arrangement about two spacing muscle 42, the one end of keeping away from the panel on the spacing muscle 42 forms chamfer 401, and chamfer 401 arranges towards support piece, and chamfer 401 can strengthen the guide effect to support piece. The reinforcing rib 43 is connected to the right side of the restriction plate 41 and is connected to the panel.

Further, in the front-rear direction, with the rear side surface of the panel as a reference surface, the height of the first limiting member 40 cannot exceed the height of the elastic arm 30, and the end of the chamfer 401 (the end of the chamfer 401 facing the panel) of the first limiting member 40 is lower than the end of the locking surface 321 away from the panel, so as to facilitate the fastening of the support member on the panel. In addition, the gap between the first limiting member 40 and the supporting member can be designed according to practical situations without special requirements.

The utility model discloses machine in air conditioning, the preset condition of panel is: the space of the left side of the supporting part is limited in the height direction, the height of the elastic arm cannot exceed the supporting part, and the buckle 21 is arranged on the left side of the supporting part when the supporting part is elastically popped. The upper end of the whole supporting piece rotates around the rotating shaft after being separated from the panel, the supporting piece can be supported on another part to ensure that the panel is stably supported when being opened, and when the panel is closed, the supporting piece is retracted and integrated with the panel through being clamped to the inner side of the elastic arm.

Because the space of the left side of the supporting member in the height direction is limited, when the elastic arm 30 is configured as a linear cantilever, the length of the elastic arm in the height direction is not enough, and the elastic requirement cannot be met, therefore, in the embodiment, the elastic arm 30 is configured as a bent elastic arm 30, and comprises a connecting section 31 as an elastic arm, a flexible locking section 32 and a limiting section 33, wherein the connecting section 31 is used for connecting the elastic arm 30 to a panel; the locking section 32 is a structure which forms the elastic arm 30 to play an elastic role, and the locking section 32 can deform and give way around the connecting position of the connecting section 31 and the panel or the connecting position of the locking section 32 and the connecting section 31, so that the supporting piece is tightly attached to the panel or is smoothly separated from the panel; the limiting section 33 is used for limiting the left and right of the supporting member, and cooperates with the first limiting member 40 on the right side of the supporting member to fix the supporting member between the two.

In this embodiment, the elastic arm 30 and the buckle 21 on the support are both disposed on the left side of the support, wherein the buckle 21 is the action point when the support is separated from the panel. Here, the elastic arm 30 is only provided on the left side of the supporter to play a role of fastening or separating the supporter, because when the handle 21 on the same side is forced to move the supporter away from the panel, the supporter will move in a direction (rightward) away from the elastic arm, that is, in a direction in which the fastening amount with the elastic arm 30 is reduced, thereby facilitating the separation of the supporter from the panel.

According to the utility model discloses machine in air conditioning makes support piece and panel limited in the space, or support piece's structure is more fixed, and under the more fixed restriction condition of separation action point, can still lock and freely separate each other, guarantees the normal function of elastic arm 30, and the reliability is high, is difficult for becoming invalid.

In the second embodiment, the first embodiment of the method,

as shown in fig. 5 to 9, the present embodiment has substantially the same structure as the first embodiment, wherein the same reference numerals are used for the same components, and the difference is only that: in the first embodiment, both the fastening handle 21 and the elastic arm 30 are disposed on the left side of the supporting member, the first limiting member 40 is disposed on the right side of the supporting member, while in the second embodiment, the fastening handle 21 is disposed on the left side of the supporting member, the elastic arm 30 is disposed on the right side of the supporting member, the first limiting member 40 is disposed on the left side of the supporting member and is opposite to the elastic arm 30 in the left-right direction, the panel is further provided with the second limiting member 50, and the second limiting member 50 is disposed on the right side of the supporting member and is opposite to the fastening handle 21 in the left-right direction. The second limiting member 50 and the first limiting member 40 have the same structure, and the limiting rib 42 of the second limiting member 50 is disposed toward the supporting member.

Further, the gap between the second position-limiting element 50 and the support, which is disposed on the same side of the support as the elastic arm 30, is smaller than the gap between the position-limiting section 33 of the elastic arm 30 and the support, so as to ensure that the support is firstly contacted with the second position-limiting element 50 and then contacted with the locking surface 321 of the elastic arm 30 when the support is separated from the panel, wherein the height of the second position-limiting element 50 is not required.

In the embodiment, the elastic arm 30 and the fastening handle 21 are respectively located at the left and right sides of the supporting member, so that the second limiting member 50 is additionally arranged at the same side of the elastic arm 30, the second limiting member 50 is arranged at one side of the elastic arm 30 adjacent to the fastening handle 21, that is, the second limiting member 50 is arranged at the upper side of the elastic arm 30, when the fastening handle 21 is stressed, the supporting member moves to the right side, that is, moves in the direction of increasing the fastening amount with the elastic arm 30, so that the supporting member and the panel are matched more and more tightly and cannot be separated. In the embodiment, after the second limiting member 50 is added on the upper side of the elastic arm 30 as a limiting stop rib, the support member preferentially contacts the second limiting member 50 when moving rightward, so as to balance the acting component force F2 in the left-right direction of the support member, prevent the support member from continuously moving in the direction of increasing the buckling amount, and simultaneously retain the component force F1 in the separating direction of the support member and the support member, so that the two members achieve the separating effect.

In addition, in the air conditioning indoor unit of the two embodiments, the position of the handle 21 of the support member on the panel is fixed, and the position of the elastic arm 30 is different. Because the space in the left height direction is limited in the preset condition, when the elastic arm 30 is arranged on the left side of the support member (in the first embodiment), the length of the locking section 32 needs to be increased, the length of the connecting section 31 needs to be reduced, the elastic arm 30 can meet the assembly space with other parts in the absolute height direction, interference collision is not generated, and meanwhile, the length of the whole elastic arm 30 can still meet the requirement of elastic abdication. Conversely, when the elastic arm 30 is disposed on the right side of the supporting member (the second embodiment), the length of the locking section 32 can be reduced, and the length of the connecting section 31 can be increased, so that the length of the overall elastic arm 30 can meet the requirement of elastic yielding.
