[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0050] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0052] The air conditioner generally includes an air conditioner indoor unit and an air conditioner outdoor unit, wherein the air conditioner indoor unit generally includes a housing, a heat exchanger assembly, an air supply assembly and an air guide assembly, etc. Optionally, the air conditioner indoor unit may also include a fresh air device, a humidifier and an oxygen generator, etc. The housing has an air inlet, an air outlet and an air duct between the air inlet and the air outlet, the heat exchange assembly and the air supply assembly are both arranged in the air duct, and the air guide assembly is arranged in the air duct or at the air outlet.

The air supply assembly includes a wind wheel (a cross-flow wind wheel or an axial flow wind wheel) for driving a driving motor of the wind wheel. The shape of the housing may be a rectangular parallelepiped shape (such as a traditional wall-mounted air conditioner indoor unit), a cylindrical shape (such as an air conditioner indoor unit), or a spherical shape (such as a wall-mounted spherical air conditioner indoor unit).

[0053] The utility model proposes an embodiment of an indoor unit of an air conditioner. In the related art, the main control board electric control box of the indoor unit of the air conditioner is installed on the air outlet frame of the main air duct at the upper part of the indoor unit, and the fresh air module is arranged at the lower part of the indoor unit. The distance between the main control board electric control box and the fresh air module is relatively far, and the motor of the indoor unit motion mechanism is mainly distributed in the middle and lower part of the indoor unit, and the distance between the main control board electric control box is also relatively far. When wiring, the main control board electric control box needs to lead out the power line from the upper part and connect it to the motor of the motion mechanism at the middle and lower part of the indoor unit, and the motor of the fresh air module respectively, which will increase the length of the power line and increase the cost. Moreover, when the distance between the main control board electric control box and the motion mechanism and the fresh air module is relatively far, the wiring is more difficult. The utility model proposes an indoor unit of an air conditioner, aiming to solve the problem that when the distance between the main control board electric control box and the motion mechanism and the fresh air module is relatively far, the wiring length of the power line is increased, resulting in higher cost.

[0054] See also Figures 1 to 6In one embodiment of the utility model, the air-conditioning indoor unit 10 includes a shell 100, an air duct assembly 200, a fresh air module 300 and an electronic control module 400; the shell 100 has an air inlet 121 and a first air outlet 131; the air duct assembly 200 is arranged in the shell 100 and is arranged corresponding to the first air outlet 131; the fresh air module 300 is arranged in the shell 100 and is located below the air duct assembly 200, and the fresh air module 300 includes a fresh air shell 310; the electronic control module 400 is installed in the fresh air shell 310.

[0055] Specifically, the housing 100 extends in the up-down direction, and the housing 100 includes a base 110, a back shell 120, an air outlet frame 130, and a top cover 140. The upper and lower ends of the back shell 120 are respectively connected to the base 110 and the top cover 140, and the air outlet frame 130 is connected to the back shell 120. The cross section of the back shell 120 is generally U-shaped, and an installation space for installing components such as the air duct assembly 200, the fresh air module 300, and the electric control module 400 is formed in the back shell 120. The air inlet 121 is formed in the back shell 120, and the first air outlet 131 is formed in the air outlet frame 130. The air duct assembly 200 is arranged in the housing 100, and the air duct assembly 200 includes a volute, a fan, a heat exchanger assembly, etc. An air supply duct is formed in the air duct assembly 200 , and the outlet side of the air supply duct is correspondingly arranged and connected to the first air outlet 131 , so that the airflow flowing into the housing 100 from the air inlet 121 can be blown out from the first air outlet 131 under the action of the air duct assembly 200 .

[0056] See also Figure 2 The fresh air module 300 is arranged in the shell 100 and is located below the air duct assembly 200. The fresh air module 300 includes a fresh air shell 310, which is the outer shell of the fresh air module 300. The fresh air shell 310 has a fresh air inlet 321 and a fresh air outlet 341, and a fresh air duct connecting the fresh air inlet 321 and the fresh air outlet 341 is formed in the fresh air shell 310. The fresh air inlet 321 is connected to the outdoor environment, and the fresh air outlet 341 is connected to the indoor environment. The setting of the fresh air module 300 can introduce outdoor fresh air into the room, thereby improving the indoor air quality.

[0057] The electric control module 400 is directly mounted on the fresh air housing 310. The electric control module 400 is the main control electric control module 400 of the air conditioner indoor unit 10, which is used to be electrically connected to the main component structure of the whole machine and perform tasks such as sending and receiving control instructions. The electric control module 400 includes an electric control housing 410, an electric control board, and a power cord connected to the electric control board. The electric control module 400 can be directly mounted on the outside of the fresh air housing 310, or a mounting position can be set inside the fresh air housing 310 to install the electric control module 400 inside the fresh air housing 310. There is no specific limitation on this.

[0058] The electric control module 400 is installed on the fresh air housing 310, which shortens the distance between the electric control module 400 and the fresh air module 300 in the housing 100. When the power cord is led out from the electric control module 400, it can be directly electrically connected to the fresh air module 300. Compared with the traditional solution of installing the electric control box on the air outlet frame 130, the present invention reduces the wiring distance between the electric control module 400 and the fresh air module 300, reduces the wiring length of the power cord, and thus reduces the cost. At the same time, it also avoids the problem of wiring difficulties when the distance between the electric control module 400 and the fresh air module 300 is too long. Furthermore, since the fresh air module 300 is arranged in the shell 100 and is located below the air duct assembly 200, that is, the air duct assembly 200 is located at the upper part of the air-conditioning indoor unit 10, the fresh air module 300 is located at the lower part of the air-conditioning indoor unit 10, and the motor of the motion mechanism of the air-conditioning indoor unit 10 is mainly distributed in the lower middle part of the air-conditioning indoor unit 10, therefore, when the electric control module 400 arranged in the fresh air shell 310 is electrically connected to the motion mechanism of the air-conditioning indoor unit 10, the wiring distance between the electric control module 400 and the motion mechanism of the air-conditioning indoor unit 10 is also reduced, the wiring length of the power cord is reduced, thereby reducing the cost, and at the same time, it also avoids the problem of wiring difficulties when the distance between the electric control module 400 and the motion mechanism of the air-conditioning indoor unit 10 is too long.

[0059] On the other hand, the terminal socket (not shown in the figure) of the air-conditioning indoor unit 10 is usually set close to the ground, that is, set near the bottom of the shell 100. The electronic control module 400 is installed on the fresh air shell 310 located in the lower part of the shell 100, which also shortens the distance between the electronic control module 400 and the terminal socket, reduces the wiring length of the power cord, reduces the cost, and makes wiring easier.

[0060] The technical solution of the utility model shortens the distance between the electric control module 400 and the fresh air module 300 in the housing 100 by setting the fresh air module 300 in the housing 100 and below the air duct assembly 200. When the power line is led out from the electric control module 400, it can be directly electrically connected to the fresh air module 300, which reduces the wiring length of the power line, reduces the cost, and makes wiring easier. At the same time, it also reduces the wiring distance between the electric control module 400 and the motion mechanism of the air conditioner indoor unit 10, reduces the wiring length of the power line, reduces the cost, and makes wiring easier.
