an air conditioning indoor unit 100 according to an embodiment of the present invention is described below.

according to the utility model discloses machine 100 in air conditioning, including chassis 1, face frame 2, automatically controlled box 3. The present invention provides a main structure of an air conditioner indoor unit 100 formed by a chassis 1 and a face frame 2.

The surface frame 2 is arranged on the chassis 1 to form a cavity for mounting the heat exchanger assembly and the fan assembly, and the electric control box 3 is arranged in the cavity.

As shown in fig. 2 and fig. 3, the electronic control box 3 includes a box body 31 and a cover 32, the cover 32 is detachably connected to the face frame 2, an opening 311 is formed on one side of the box body 31, and the cover 32 is connected to the box body 31 in a matching manner to close the opening 311.

As shown in fig. 3, two opposite ends of box 31 are snap-connected to chassis 1 to avoid using screws to connect box 31 to chassis 1, wherein the snap-in direction of chassis 1 to the snap-connection of two opposite ends of box 31 is opposite. The opposite directions of the clamping are opposite, the clamping directions are different, when the buckle at one end is clamped into the chassis 1 upwards, the buckle at the other end is clamped into the chassis 1 downwards; when the buckle at one end is clamped into the chassis 1 forwards, the buckle at the other end is clamped into the chassis 1 backwards; when the buckle at one end is clamped into the chassis 1 leftwards, the buckle at the other end is clamped into the chassis 1 rightwards.

According to the above structure, the utility model discloses indoor unit of air conditioner 100, the both ends of box body 31 adopt the card to go into to form the joint cooperation between opposite direction's buckle and the chassis 1, when the automatically controlled box 3 of installation, only need cooperate lid 32 on box body 31, are connected the one end and the chassis 1 buckle of box body 31 again, and the installation can then be accomplished with the chassis 1 buckle connection to the other end of box body 31. In the process, screws are not needed for connection and matching between the box body 31 and the chassis 1, the assembly and disassembly are convenient, and the assembly efficiency is high.

Because the two opposite ends of the box body 31 are respectively in clamping fit with the chassis 1, in the installation process, the buckle at one end is firstly clamped, and the buckle at the other end is convenient for adjusting the direction and aligning the clamping position. When the box body 31 and the chassis 1 are clamped in place, the buckle connection structures at the two opposite ends can ensure that the installed box body 31 is fixed relative to the chassis 1, and the box body 31 is not easy to be easily separated from the chassis 1, for example, when the box body 31 moves towards the matching position of the buckle structure at one end, the box body is limited by the matching structure of the chassis 1 at the side; correspondingly, when the box body 31 moves towards the matching part of the snap structure at the other end, the box body is limited by the matching structure of the chassis 1 at the side, namely when the snap structures at the two ends of the box body 31 are installed in place, the relative position between the box body 31 and the chassis 1 is not easy to change, and the box body 31 is installed on the chassis 1 and locked on the chassis 1.

Lid 32 detachably of automatically controlled box 3 connects on face frame 2, makes automatically controlled box 3 have three fitting surfaces at least for face frame 2, chassis 1, and three fitting surface is respectively with two opposite flank of chassis 1 complex to and with face frame 2 complex contact surface, make automatically controlled box 3 convenient assembling not only, and stable after the assembly, difficult relocation.

It can be understood that, compare and use screw structure and buckle structure simultaneously and be connected chassis and automatically controlled box among the prior art, the utility model discloses need not to use the screw, alright install automatically controlled box 3 on chassis 1 steadily, greatly improved the installation effectiveness. And compare in prior art chassis and the buckle structure of automatically controlled box setting all in same direction, perhaps the chassis all inclines in adjacent with the buckle structure of automatically controlled box setting, the utility model discloses a buckle structure is small in quantity, and is spacing stable, is difficult for deviating from after connecting the cooperation. Compare spacing through the brace rod between face frame 2 and the automatically controlled box 3 among the prior art, the utility model discloses a form between lid 32 and the face frame 2 and can dismantle the connection, it is more stable after connecting, rock around can not.

In some embodiments of the present invention, as shown in fig. 3, two opposite sides of the box 31 in the length direction are respectively connected to the chassis 1 by snapping. The two sides may be upper and lower sides, left and right sides, or front and rear sides.

Alternatively, as shown in fig. 5, the upper and lower sides of the box 31 are respectively connected to the chassis 1 by snap-fitting. Because box 31 receives its own gravity, the bottom fitting surface between box 31 and chassis 1 can easily form the joint because of the action of the gravity of box 31 itself when assembling, and the buckle structure of bottom is difficult for the dropout, because when the air conditioning indoor unit 100 who has box 31 is installed, the position generally can not change, therefore the buckle structure of bottom keeps cooperating under the action of the gravity that box 31 lasts, and box 31 and chassis 1 contact closely. In addition, even in the transportation process, the electric control box 3 moves up and down under the action of vibration, the buckling structure on the upper side surface can limit the electric control box 3, and the electric control box 3 is relatively stably arranged in the chassis 1.

Optionally, the left and right sides of the box 31 are respectively connected to the chassis 1 by a snap fit.

Optionally, the front and rear sides of the box 31 are respectively connected to the chassis 1 by a snap fit.

In some embodiments of the present invention, the chassis 1 is provided with at least three side surfaces of the periphery of the box 31 respectively with the matching plates 11 for limiting. The mating plate 11 here includes the mating surface on the chassis 1 with the snap structure between the chassis 1 and the box 31, and also includes the contact surface on the chassis 1 without the snap structure between the chassis 1 and the box 31. When at least three matching surfaces are formed and two matching surfaces are oppositely arranged, one end of the box body 31 is limited in the three directions of height, width and length, so that when the box body 31 is in contact matching with the three sides of the chassis 1, a part of the structure of the box body 31 is embedded into the space, and the box body 31 and the chassis 1 are stably matched.

Optionally, as shown in fig. 5, the chassis 1 is provided with engaging plates 11 on the upper side, the lower side, and the left side of the periphery of the box 31, respectively.
