An embodiment of the disclosure provides an air-conditioning indoor unit, and with reference to FIG. 1 to FIG. 3, the air-conditioning indoor unit includes a housing 10, an evaporator 20, and an electric control box 30. An air duct 10a is formed in the housing 10; the evaporator 20 is arranged in the air duct 10a; and the electric control box 30 is arranged at a side of the evaporator 20, and at least a part of area of the electric control box 30 is located in the air duct 10a.

Another embodiment of the disclosure provides an air conditioner, the air conditioner includes the air-conditioning indoor unit described in any one of the embodiments of the disclosure.

The air-conditioning indoor unit described in the embodiments of the disclosure may be a ceiling unit, a ducted unit, etc.

The air duct 10a is a channel through which airflow circulates in the housing 10, that is, airflow from outside enters the air duct 10a from an air return port 10d of the air-conditioning indoor unit, exchanges heat at the evaporator 20, and then flows out from an air outlet 40a of the air-conditioning indoor unit.

There are multiple manners for forming the air duct 10a. For example, with reference to FIG. 3, an air duct shell 60 may be arranged in the housing 10, and the air duct shell 60 cooperates with the housing 10 to define the air duct 10a.

In some embodiments, the air duct 10a may also be directly formed of an inner space of the housing 10, instead of the air duct shell 60.

There may also be various structural forms of the housing 10. Exemplarily, with reference to FIG. 4 and FIG. 5, the housing 10 may consist of an underpan 11, a first side plate 12 and a second side plate 13. The underpan 11 may use an integrally molded structure, that is, a bottom plate 111, a front side plate 112 and a rear side plate 113 of the underpan 11 may be integrally molded, and when the housing 10 is assembled, it only requires the first side plate 12 to be covered at the opened portion at a side of the underpan 11, and the second side plate 13 to be covered at the opened portion at another side of the underpan 11. Operations are simple and convenient, so that assembly efficiency of the housing may be improved.

In some embodiments, the underpan 11 may not use the integrally molded structure. For example, each of the bottom plate 111, the front side plate 112 and the rear side plate 113 may be an individual single plate, and they are assembled together during assembly.

The electric control box 30 is arranged at a side of the evaporator 20, and at least a part of area of the electric control box 30 is located in the air duct 10, therefore when the air-conditioning indoor unit is in an operation state, airflow flowing through the evaporator 20 may take away heat generated by the electric control box 30, so that a good heat dissipation function on the electric control box 30 may be achieved, and thus the heat dissipation effect of the electric control box 30 may be improved.

In an embodiment, with reference to FIG. 1 to FIG. 3, the electric control box 30 is located at a side of the evaporator 20 in a lateral direction.

When the air-conditioning indoor unit is in the operation state, negative pressure may be generated at both sides of the evaporator 20 in the lateral direction. Therefore, the electric control box 30 is arranged at a side of the evaporator 20 in the lateral direction, so that the heat generated by the electric control box 30 may be taken away better, and thus the heat dissipation effect of the electric control box 30 may be further improved.

There are multiple manners for arranging the electric control box 30. Exemplarily, with reference to FIG. 1 and FIG. 4, a part of area of the housing 10 is recessed toward an inner side of the housing 10 to form an installation space 10b communicated with the air duct 10a, and at least the part of area of the electric control box 30 is arranged in the installation space 10b.

Specifically, the electric control box 30 arranged in the installation space 10b may allow at least one of a sidewall, a bottom wall or a top wall of the electric control box 30 to close connection between the air duct 10a and the installation space 10b only (i.e., an arrangement shown in FIG. 3), which is equivalent to that an area of the electric control box 30 intended to close the connection between the air duct 10a and the installation space 10b forms a part of sidewall of the air duct 10a, and it may also be that a part of area of the electric control box 30 extends into the air duct 10a from the connection between the air duct 10a and the installation space 10b.

The installation space 10b formed on the housing 10 may not only facilitate installation of the electric control box 30, but also make an overall structure of the air-conditioning indoor unit more compact.

Furthermore, with reference to FIG. 1 to FIG. 4, an opening 10c communicated with the air duct 10a is provided at a side of the housing 10, and a part of sidewall of the housing 10 located at the opening 10c side is recessed to form the installation space 10b.

Specifically, the air return port 10d and/or the air outlet 40a of the air-conditioning indoor unit may be provided at the opening 10c of the housing 10.

With reference to FIG. 1 to FIG. 4, the benefit of forming the installation space 10b by recessing the part of sidewall of the housing 10 located at the opening 10c side is that when the electric control box 30 is installed in the installation space 10b, the sidewall at a side of the electric control box 30 and at least a part of the bottom wall may be located in the air duct 10a, which is equivalent to increasing an area of the electric control box 30 contacting with airflow in the air duct 10a, so that better heat dissipation of the electric control box 30 may be achieved.

In a specific embodiment, with reference to FIG. 1 and FIG. 2, the air-conditioning indoor unit includes an air outlet frame 40, a fan and a water collection tray 50, and the air outlet frame 40 is provided with an air outlet 40a; the air outlet frame 40 and the fan are arranged in the air duct 10a, the air outlet 40a is communicated with the air duct 10a and faces toward the opening 10c, the fan and the evaporator 20 are arranged at a same side of the air outlet frame 40, and the fan is located at a side of the evaporator 20 away from the opening 10c; and the water collection tray 50 is arranged at the opening 10c and faces toward the evaporator 20, and the water collection tray 50 avoids a part of area of the opening 10c, so that the area of the opening 10c avoided by the water collection tray 50 forms an air return port 10d.

That is, the air outlet 40a and the air return port 10d of the air duct 10a may be arranged at the same side of the housing 10, and the water collection tray 50 is intended to hold condensed water generated by the evaporator 20. Two air return ports 10d are separated by the water collection tray 50 shown in FIG. 1 at the opening 10c, to form. In some embodiments, the water collection tray 50 may also be separated at the opening 10c, to form one air return port 10d or more than two air return ports 10d.

When the fan operates, airflow from outside enters the air duct 10a from the air return port 10d, exchanges heat at the evaporator 20, and then flows out from the air outlet 40a of the air outlet frame 40. When the airflow flows through the evaporator 20, it takes away heat generated by the electric control box 30, and thus may achieve a heat dissipation function on the electric control box 30.

In some embodiments, the installation space 10b may not be formed in the housing 10. For example, the air duct 10a may be provided with a communication port communicated with outside, and the electric control box 30 is arranged on an outer surface of the housing 10. It may be that a sidewall at a side of the electric control box 30 closes the communication port, which is equivalent to that the sidewall of the electric control box 30 closing the communication port forms a part of sidewall of the air duct 10a. It may also be that the part of area of the electric control box 30 extends into the air duct 10a from the communication port.

In an embodiment, with reference to FIG. 3, the electric control box 30 includes a box body 31 and a box cover 32 openably and closably covered on the box body 31, the box body 31 is connected to the housing 10, and the box cover 32 is located out of the housing 10.

The box cover 32 is arranged out of the housing 10, which may facilitate a maintenance personnel to open the box cover 32 to check and fix components in the box body 31, to improve convenience of maintenance.

In an embodiment, with reference to FIG. 3, an air switch 33 may be arranged in the box body 31, and the air switch 30 is configured to control on or off of a power supply of the air-conditioning indoor unit. That is, during the maintenance personnel's maintenance, the maintenance personnel may toggle a control handle 33a of the air switch 33 first, to turn off the power supply of the air-conditioning indoor unit. After the maintenance is completed, the maintenance personnel may toggle the control handle 33a of the air switch 33 again, to turn on the power supply of the air-conditioning indoor unit. Therefore, convenience and safety of the maintenance may be further improved.

There are multiple structural forms of the electric control box 30. Exemplarily, with reference to FIG. 6 and FIG. 7, the box body 31 includes a main box 311 and a secondary box 312 connected to the main box 311, the box cover 32 includes a main box cover 321, and the electric control box 30 includes an electric control board 34; and a side of the main box 311 and a side of the secondary box 312 are opened, the electric control board 34 is arranged in the main box 311, the main box cover 321 is openably and closably covered at the opened portion of the main box 311, and the air switch 33 is arranged in the secondary box 312.

Specifically, the main box 311 is mainly intended for components such as the electric control board 34 to be arranged in it, and the secondary box 312 is mainly intended for the air switch 33 to be arranged in it, that is, the electric control board 34 and the air switch 33 may be arranged separately. With reference to FIG. 8 and FIG. 9, in order to facilitate installing and fixing the electric control board 34 and the air switch 33, an installation box 35 may be arranged in the main box 311, the electric control board 34 may be fixed in the installation box 35; a support frame 36 may be arranged in the secondary box 312, the air switch 33 is fixed on the support frame 36. During maintenance, the maintenance personnel toggles the control handle 33a of the air switch 33 in the secondary box 312 first, to turn off the power supply of the air-conditioning indoor unit, and then opens the main box cover 321, to check and fix components in the main box 311, such as the electric control board 34, etc.

With reference to FIG. 7 to FIG. 9, in order to facilitate wiring, multiple first wire passage ports 311a may be arranged on the main box 311, and multiple second wire passage ports 312a may also be arranged on the secondary box 312. The number of first wire passage ports 311a and second wire passage ports 312a may be determined according to requirements. Exemplarily, with reference to FIG. 8 and FIG. 9, since the secondary box 312 is mainly intended for the air switch 33 to be arranged in it, the secondary box 312 may be provided with only two second wire passage ports 312a, one of the two second wire passage ports 312a may be arranged on a sidewall of the secondary box 312, and another one of the two second wire passage ports 312a may be arranged on a bottom wall of the secondary box 312, to facilitate a user to select an appropriate second wire passage port 312a to make wire go out according to actual requirements.

Furthermore, in order to facilitate toggling the control handle 33a of the air switch 33, the secondary box 312 may be arranged at a side of the main box 311 away from the evaporator 20. That is, compared with the electric control board 34, the air switch 33 may be arranged at a position close to an outer side of the electric control box 30, so that the maintenance personnel may touch the air switch 33 first.

In a specific embodiment, with reference to FIG. 3, the main box 311 is arranged in the installation space 10b, the secondary box 312 is arranged out of the installation space 10b and located at a side of the main box 311 away from the evaporator 20, and the main box 311 and the secondary box 312 are connected to the housing 10.

That is, when the housing 10 is formed with the installation space 10b, the main box 311 may be arranged in the installation space 10b to mainly dissipate heat of components in the main box 311, while the secondary box 312 is arranged out of the installation space 10b and located at a side of the main box 311 away from the evaporator 20, to facilitate the maintenance personnel to toggle the control handle 33a of the air switch 33.

Furthermore, the main box 311 and the secondary box 312 may also be fastened and connected to the housing 10 with fasteners such as screws, bolts, etc. Therefore, it may ensure that the main box 311 and the secondary box 312 may be securely fixed on the housing 10.

In an embodiment, with reference to FIG. 3, FIG. 6 and FIG. 7, the box cover 32 further includes a secondary box cover 322 provided with an avoidance port, the secondary box cover 322 is openably and closably covered at the opened portion of the secondary box 312, and a control handle 33a of the air switch 33 extends out of the secondary box cover 322 from the avoidance port.

The secondary box cover 322 may protect main structures of the air switch 33. Since it is usually unnecessary to check and fix the air switch 33, the secondary box cover 322 may remain in a normally closed state, and the maintenance personnel only needs to toggle the control handle 33a extending out of the secondary box cover 322 from the avoidance port, without opening the secondary box cover 322, operations are simple and convenient.

In some embodiments, the secondary box cover 322 may not be provided with the avoidance port, that is, the control handle 33a of the air switch 33 may also be located in the secondary box 312, and during maintenance, the maintenance personnel may open the secondary box cover 322 and then toggle the control handle 33a.

In some embodiments, the electric control box 30 may not be provided with the main box 311 and the secondary box 312, that is, all components such as the electric control board 34, the air switch 33 or the like in the electric control box 30 may be arranged in the same box body 31.
