The opening 220 is opened in the front end plate 210, part of the heat exchanger 400 is exposed at the opening 220, the opening 220 is convenient for maintenance personnel to maintain or repair the heat exchanger 400, and the panel 300 can realize the function of opening the opening 220 or shielding the opening 220, so that the appearance of the indoor unit of the air conditioner is attractive, and meanwhile, the indoor unit of the air conditioner is convenient for maintenance personnel to maintain or repair.

Referring to fig. 1 and 3, the air conditioner indoor unit according to the embodiment of the present invention further includes an electric control box assembly 500. At least a part of the electronic control box assembly 500 is disposed in the installation space. The electronic control box assembly 500 includes an electronic control box 510 and a bracket 520, and the bracket 520 can be mounted to the chassis 100, or to the heat exchanger 400, or to both the chassis 100 and the heat exchanger 400. The electronic control box 510 is disposed 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 in which the electric control boxes 510 are installed on the left side and the right side of the heat exchanger 400, the air-conditioning indoor unit of the embodiment of the utility model can effectively shorten the total length of the air-conditioning indoor unit, so that the air-conditioning indoor unit is more compact, and the cost of packaging, transportation and storage is reduced.

When the heat exchanger 400 needs to be cleaned, a maintenance worker needs to firstly detach the electric control box 510 from the bracket 520, and the electric control box 510 is convenient to detach and mount, so that the indoor unit of the air conditioner provided by the embodiment of the utility model cannot affect the cleaning of the heat exchanger 400, and the convenience of cleaning the heat exchanger 400 is ensured.

Referring to fig. 2, 3 and 4, it can be understood that the heat exchanger 400 and the electrical control box 510 are both extended in the left-right direction in fig. 3 (i.e., the length direction of the panel 200 in fig. 2). The maximum dimension of the opening 220 along the length direction of the bezel 200 is defined as a, and it can be understood that the dimension of the opening 220 along the length direction of the bezel 200 is not completely consistent, for example, the upper portion of the opening 220 has a smaller dimension, and the lower portion of the opening 220 has a larger dimension, and at this time, the electrical control box 510 can be moved to the lower portion of the opening 220 for being taken out after being detached from the bracket 520. It should be noted that, in the air conditioning indoor unit according to the embodiment of the present invention, if the plurality of openings 220 are provided and are independent from each other, that is, the plurality of openings 220 are not communicated with the front end plate 210, the size of the opening 220 refers to the size of the opening 220 at the position where the partial structure of the electrical control box 510 is located; if the opening 220 is provided in a plurality and at least partially communicates with the front plate 210, the size of the opening 220 refers to the total size of the opening 220 where part of the structure of the electrical control box 510 is located and the opening 220 communicating with the opening 220. It is understood that the communication between the plurality of openings 220 includes the structure of the front plate 210 being configured to communicate, and also includes the structure of the front plate 210 being configured not to communicate, but some parts of the front plate 210 can be manually disassembled to achieve the communication between the plurality of openings 220.

In 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 in the front-rear direction (which can also be understood as the front-rear direction of the face frame 200), and it is 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 at the rear.

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 electrical 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 satisfy: b < a + c, the overall dimension of the electrical box 510 can meet the requirement of being taken out from the opening 220. It can be understood 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 electrical control box 510 can be taken out under the condition that the electrical control box 510 is ensured to form a certain included angle with the opening 220 after being detached from the bracket 520.

It will be appreciated that the maximum dimension b of the electrical control box 510 along the length direction satisfies:

it can be understood that, according to the pythagorean theorem, the square of the triangular inclined plane is equal to the sum of the squares of the two right-angle sides, so that when the above conditions are met, the electronic control box 510 can be taken out at least under the condition that the electronic control box 510 and the opening 220 are at a certain included angle after being detached from the bracket 520.
