Referring to fig. 1 and 3, the indoor unit of an air conditioner according to an embodiment of the present invention further includes an electronic control box assembly 500. At least a portion of the electronic control box assembly 500 is disposed within the mounting space. The electric control box assembly 500 comprises an electric control box 510 and a bracket 520, wherein the bracket 520 can be mounted on the chassis 100, or mounted on the heat exchanger 400, or mounted on both the chassis 100 and the heat exchanger 400. The electronic control box 510 is provided at the front end of the heat exchanger 400 (i.e., the end of the heat exchanger 400 facing the opening 220). Compared with the prior art that the electric control box 510 is arranged at the left side and the right side of the heat exchanger 400, the air conditioner indoor unit of the embodiment of the invention can effectively shorten the total length of the air conditioner indoor unit, make the air conditioner indoor unit more compact, and reduce the cost of packaging, transportation and storage.

In the air conditioner indoor unit of the embodiment of the invention, the electric control box 510 is detachably connected with the bracket 520, and the electric control box 510 can be arranged so that part of the structure is exposed to the opening 220, or the whole structure is exposed to the opening 220.

Referring to fig. 2, 3 and 4, it is understood that the heat exchanger 400 and the electronic control box 510 are both disposed to extend in the left-right direction in fig. 3 (i.e., the length direction of the face frame 200 in fig. 2). Defining the maximum dimension of the opening 220 along the length direction of the bezel 200 as a, it will be appreciated that the dimension of the opening 220 along the length direction of the bezel 200 is not completely uniform, for example, the dimension of the upper portion of the opening 220 is smaller, and the dimension of the lower portion of the opening 220 is larger, and at this time, the electronic control box 510 can be removed from the bracket 520 and moved to the lower portion of the opening 220 for removal. It should be noted that, in the indoor unit of an air conditioner according to the embodiment of the present invention, if the opening 220 is provided with a plurality of openings that are independent of each other, that is, the plurality of openings 220 are not connected to the front end plate 210, the size of the opening 220 refers to the size of the opening 220 where the part of the structure of the electronic control box 510 is located; if the opening 220 is provided in plurality and at least partially communicates with the front end plate 210, the size of the opening 220 refers to the total size of the opening 220 where a part of the structure of the electronic control box 510 is located and the opening 220 communicating with the opening 220. It will be appreciated that communication between the plurality of openings 220 includes the case where the structure of the front end plate 210 is designed to communicate, as well as the case where the structure of the front end plate 210 is designed not to communicate, but the case where communication between the plurality of openings 220 can be achieved after manual disassembly of certain components on the front end plate 210.

Referring to fig. 3, the maximum dimension of the electronic control box 510 in the left-right direction is defined as b, and it is understood that the external shape of the electronic control box 510 is not necessarily a regular rectangular parallelepiped structure, and may be provided with a protruding structure, such as lugs for fixing, etc. In the front-rear direction (which may also be understood as the front-rear direction of the face frame 200) of fig. 4, the maximum distance between the front end plate 210 and the front end surface of the heat exchanger 400 is defined as c, it may be understood that the heat exchanger 400 may be configured to be inclined forward and downward, and the electronic control box 510 may be provided on the heat exchanger 400 located rearward.

Therefore, when the maximum dimension a of the opening 220 in the length direction of the face frame 200, the maximum dimension b of the electronic control box 510 in the left-right direction, and the maximum distance c between the front end plate 210 and the front end surface of the heat exchanger 400 are satisfied: b < a+c, the external dimensions of the electronic control box 510 can meet the requirement of being taken out from the opening 220. It can be appreciated that, according to the characteristic that one side of the triangle is smaller than the sum of the other two sides, when the above condition is satisfied, the electronic control box 510 can be taken out under the condition that a certain included angle between the electronic control box 510 and the opening 220 is ensured after the electronic control box 510 is detached from the bracket 520.

It can be appreciated that the maximum dimension b of the electronic control box 510 in the length direction satisfies:

it can be appreciated that, according to the pythagorean theorem, the square of the triangle inclined plane is equal to the sum of the squares of the two right-angle sides, so that when the above condition is satisfied, the electric control box 510 can be taken out under the condition that at least a certain included angle between the electric control box 510 and the opening 220 is ensured after the electric control box 510 is detached from the bracket 520.

Referring to fig. 2 and 3, it can be understood that the electric control box 510 is disposed between the heat exchanger 400 and the opening 220, and the electric control box 510 is disposed corresponding to the opening 220, so that the electric control box 510 can be completely exposed in the opening 220, thereby facilitating the electric control box 510 to be removed after being detached from the bracket 520. The electric control box 510 and the support 520 can be detachably connected through screw connection, buckle connection and other modes, and the detachable connection structure is exposed to the opening 220, for example, the screw is exposed to the opening 220, so that maintenance personnel can conveniently use tools to detach, the detachment and installation difficulty between the electric control box 510 and the support 520 is reduced, the detachment and installation efficiency of the electric control box 510 is improved, and abrasion or accidental injury to the parts such as the face frame 200 in the maintenance process can be effectively avoided.
