Referring to fig. 1, fig. 1 is a schematic view of an air conditioning indoor unit 1 according to an embodiment of the present utility model. The present utility model provides an air conditioning indoor unit 1, which air conditioning indoor unit 1 may generally include a cabinet 10. The interior of the machine shell 10 defines a heat exchange cavity, the rear side of the machine shell 10 is provided with an air inlet grille 12, a heat exchange airflow inlet is formed on the air inlet grille 12, the front side of the machine shell 10 is provided with a heat exchange airflow outlet which is open forwards, and a heat exchanger and a fan are arranged in the heat exchange cavity. When the air conditioner indoor unit 1 works, the fan is started to enable air in the indoor space to enter the heat exchange cavity from the heat exchange airflow inlet and exchange heat with the heat exchanger, and the air after heat exchange is discharged into the room from the heat exchange airflow outlet, so that the indoor temperature is adjusted.

In some embodiments, the indoor unit 1 may further include an outlet grille 20, where the outlet grille 20 is disposed at the front of the casing 10, and serves to protect a user, decorate, etc. The outlet grill 20 may be provided with an air flow outlet so that the heat exchange air flow discharged from the air outlet penetrates into the room.

Referring to fig. 1 and 2, fig. 2 is a schematic view illustrating a mounting relationship between a mounting frame 110 and an air outlet grill 20, which is viewed from a viewing angle (generally from front to rear) in an indoor unit of an air conditioner according to an embodiment of the present utility model.

Further, the casing 10 further includes a mounting frame 110 mounted on the front side of the air outlet, and the mounting frame 110 has a hollow structure. The outlet grill 20 may include a body wall 210, and an air flow outlet may be provided on the body wall 210, and the body wall 210 covers the hollow structure of the mounting frame 110.

The outlet grill 20 may further include a side wall 220 formed at the periphery of the body wall 210 and extending rearward, the side wall 220 having a contour that matches the inner rim 112 of the mounting frame 110. When the air outlet grille 20 is installed, the side wall 220 is connected with the inner ring 112 of the installation frame 110 in a form fit manner, so that stability and sealing performance between the air outlet grille 20 and the inner ring 112 of the installation frame 110 are improved.

In some embodiments, the indoor unit 1 may further include a fastener 30, where the fastener 30 may lock/unlock the grille 20 and the mounting frame 110.

Referring to fig. 2 to 5, fig. 3 is an enlarged view of a portion a of fig. 2, fig. 4 is a schematic view of a mounting frame 110 and an air outlet grill 20, which are seen from another view angle (approximately from the rear to the front) of the air conditioning indoor unit 1 according to an embodiment of the present utility model, and fig. 5 is an enlarged view of a portion B of fig. 4.

Specifically, the inner ring 112 of the mounting frame 110 is provided with a clamping hole 114, the side wall 220 is provided with a penetrating hole 222 opposite to the clamping hole 114, the fastener 30 has a clamping end 332 opposite to the penetrating hole 222, and the fastener 30 is configured to slide along the inner side of the main body wall 210 between an extended position and a retracted position.

When the latch 30 is in the extended position, the latch end 332 extends from the through hole 222 to mate with the latch hole 114 to lock the grille 20 to the housing 10 (as shown in fig. 5).

When the catch 30 is in the retracted position, the catch end 332 is retracted inside the body wall 210 to release the lock between the grille 20 and the housing 10.

When the air outlet grille 20 is installed, an installer can operate the fastening piece 30 to be in the retracted position, so that the fastening end 332 is prevented from being fastened to the inner ring 112 of the installation frame 110 when the air outlet grille 20 is installed on the installation frame 110. After the outlet grille 20 is mounted to the inner ring 112 of the mounting frame 110, the installer can operate the clip member 30 to reach the extended position, and the clip end 332 of the clip member 30 passes through the through hole 222 of the side wall 220 and is inserted into the clip hole 114 of the mounting frame 110, so as to lock the outlet grille 20 to the casing 10.

When the air outlet grille 20 is detached, an installer can operate the fastening member 30 to be in the retracted position, and the fastening end 332 of the fastening member 30 is retracted inside the main body wall 210, so that the air outlet grille 20 can be easily removed from the mounting frame 110.

Therefore, in the air conditioner indoor unit 1 of the embodiment, the fastening piece 30 is adopted to replace a traditional fastening piece to fix the air outlet grille 20, so that the number of parts is reduced, the disassembly difficulty is reduced, and a user can disassemble and assemble the air outlet grille 20 by himself so as to maintain the air outlet grille.

In some embodiments, the indoor unit 1 may further include an elastic pre-tightening member disposed on the fastening member 30 and configured to provide a force for maintaining the fastening member 30 in the extended position.

That is, the elastic pre-tightening member can urge the catch member 30 to be in the extended position, so that the air outlet grille 20 can be stably locked on the mounting frame 110, and accidents caused by that the air outlet grille 20 is easily unlocked can be avoided.

Referring to fig. 5, in some embodiments, the inner surface of the main body wall 210 is provided with a collision wall 212 at both sides of the sliding direction of the latch 30. The elastic pre-tightening member may include two elastic arms 40, where the two elastic arms 40 are respectively formed at two sides of the sliding direction of the fastening member 30 and respectively extend away from the fastening member 30, so that the ends respectively abut against a surface of the abutting wall 212 facing the side wall 220. The resilient pretensioner arms are configured to bring the two resilient arms 40 into a natural state when the catch 30 is in the extended position, and the two resilient arms 40 are respectively pressed by the two abutting walls 212 to generate a resilient force that maintains the catch 30 in the extended position during sliding of the catch 30 from the extended position to the retracted position.

The above "natural state" is understood to mean that the elastic arm 40 is not deformed when the fastener 30 is in the extended position, that is, the elastic arm 40 does not generate any force.

In this embodiment, the extending directions of the two abutting walls 212 are perpendicular to the extending direction of the fastener 30, and since the end of the elastic arm 40 abuts against the side of the abutting wall 212 facing the side wall 220, when the fastener 30 slides from the extended position to the retracted position, the elastic arm 40 is gradually deformed by the side wall 220, and the elastic arm 40 generates a force to the fastener 30 to return the fastener 30 to the extended position.

When the air outlet grille 20 is installed, an installer needs to operate the buckling piece 30 to be in the retracted position, after the air outlet grille 20 is installed on the inner ring 112 of the installation frame 110, the installer can directly remove the acting force for enabling the buckling piece 30 to be in the retracted position, and the buckling piece 30 naturally returns to the extended position under the promotion of elastic acting force, so that the operation is simple, stable and reliable.

In addition, since the two elastic arms 40 are formed on two sides of the sliding direction of the fastener 30 and extend in a direction away from the fastener 30, the two elastic arms 40 can also play a limiting role, for example, when the fastener 30 is in the extended position, the two elastic arms 40 can just abut against the inner side of the through hole 222, so as to prevent the fastener 30 from completely extending into the mounting frame 110, thereby improving reliability.

In other embodiments, the resilient pretensioning member may be provided as a return member, such as a compression spring, disposed between the catch member 30 and the mounting frame 110 such that the compression spring is compressed to generate a resilient force that maintains the catch member 30 in the extended position as the catch member 30 slides from the extended position to the retracted position.

Referring to fig. 5, in some embodiments, one of the inner surface of the body wall 210 and the catch 30 is provided with a limit groove 214 extending in the sliding direction, and the other is provided with a limit post 118, the limit post 118 sliding along the limit groove 214 to restrict the sliding distance of the catch 30 so that it can only slide between the extended position and the retracted position.

The design positions of the limiting groove 214 and the limiting post 118 can be selected according to practical situations, so long as the limiting groove 214 and the limiting post can be matched and limited. For example, as shown in fig. 5, the limit groove 214 is provided on the buckle 30, and the limit post 118 is provided on the inner surface of the body wall 210. Of course, the limit post 118 may be disposed on the fastener 30, and the limit groove 214 may be disposed on the inner surface of the body wall 210.

Referring to fig. 5, in some embodiments, the inner surface of the body wall 210 is provided with a sliding groove 320 extending in the sliding direction. The latch 30 is slidably disposed in the sliding groove 320 to restrict the sliding track of the latch 30.

Further, the top ends of the two side groove walls of the sliding groove 320 are provided with anti-releasing grooves 322 to prevent the clip 30 from being released from the sliding groove 320.

When the sliding groove 320 is configured, it should be noted that the extending direction of the sliding groove 320 is opposite to the through hole 222, so that the fastening piece 30 can be ensured to pass through the through hole 222. And the depth of the sliding groove 320 should be slightly greater than the thickness of the buckle 30 so that the anti-trip 322 does not increase the resistance of the buckle 30 when sliding.

In some embodiments, the number of snaps 30 is multiple, such as two, three, or more. Correspondingly, the side surrounding wall 220 needs to be provided with a through hole 222 at a corresponding position of each fastener 30, and the inner ring 112 of the mounting frame 110 needs to be provided with a clamping hole 114 at a corresponding position of each through hole 222.

When a plurality of fastening pieces 30 are distributed, at least one fastening piece 30 is arranged on two lateral sides of the air outlet grille 20 to ensure the firmness of the air outlet grille 20. For example, the number of the buckling pieces 30 is two, and the two buckling pieces 30 are respectively arranged at two lateral sides of the air outlet grille 20.

As to whether the positions and the number of the snap members 30 on both lateral sides of the outlet grill 20 need to be symmetrical, this may be configured according to circumstances, and the present utility model is not limited thereto.

Referring to fig. 2, 5 to 7, fig. 6 is an exploded view of the mounting frame 110 and the outlet grill 20 of the indoor unit 1 according to an embodiment of the present utility model, and fig. 7 is a view of the fastening member 40 of the indoor unit 1 according to an embodiment of the present utility model.

In some embodiments, the fastener 30 may further include a clamping portion 330 and an operating portion 340, wherein a first end of the clamping portion 330 serves as the clamping end 332, and a second end of the clamping portion 330 is connected to the operating portion 340. The body wall 210 has a central portion defining a perforated area 230, a rearwardly extending flange 240 formed on a periphery of the perforated area 230, and a connecting hole 242 formed on the flange 240. The latch 30 is configured such that the second end of the engaging portion 330 extends out of the connecting hole 242, so as to dispose the operating portion 340 in the hole forming region 230.

In this embodiment, the body wall 210 has a center defining an apertured region 230, and the apertured region 230 may be partitioned into grid-like airflow outlets by grid strips.

Since the clip 30 slides along the body wall 210, that is, the clip 30 slides along the body wall 210 outside the hole area 230. For example, the catch 30 may be disposed above the apertured region 230 and up to an extended position and down to a retracted position. For another example, the catch 30 may be disposed to the left of the perforated area 230, to the left to the extended position, and to the right to the retracted position. For another example, the catch 30 may be positioned to the right of the perforated section 230, to the right to the extended position, and to the left to the retracted position.

A flange 240 extending rearward is formed on the periphery of the hole forming region 230, that is, the flange 240 borders the hole forming region 230, the flange 240 has a connection hole 242, and the second end of the locking portion 330 passes through the connection hole 242 to position the operation portion 340 in the hole forming region 230. Because the space of the hole forming region 230 is large, the operation hole is formed in the hole forming region 230 to facilitate the user's operation.

Further, the front portion of the operation portion 340 protrudes from the body wall 210 so as to apply a force to the operation portion 340.

Referring to fig. 6, in some embodiments, the bottom of the exit grill 20 has a plurality of positioning posts 250. The bottom of the mounting frame 110 has a plurality of positioning holes 116, and the positioning columns 250 are disposed in the positioning holes 116 in a one-to-one correspondence, so that the bottom of the air grid 20 is pre-mounted on the mounting frame 110.

When the air-out grille 20 is installed, an installer can insert the positioning column 250 of the air-out grille 20 into the positioning hole 116 of the installation frame 110, so that the bottom of the air-out grille 20 is pre-installed on the installation frame 110, then operate the operation part 340 of the fastener 30 to enable the operation part to be in a retracted position, so that the air-out grille 20 is completely installed on the inner ring 112 of the installation frame 110, finally release the operation part 340 of the fastener 30, and lock the air-out grille 20 and the casing 10 by using the clamping end 332 of the fastener 30 under the action of the elastic pre-tightening piece.
