In particular, during operation of the air conditioning indoor unit, the fan 106 is operated and drives air flow in the drive chamber 132, which maximizes the air flow rate in the drive chamber 132 throughout the air duct 104.

Wherein the sealing member 124 is disposed at the notch 110 of the electronic control box 108 and is operable to seal the gap between the notch 110 and the heat sink 114.

A fourth embodiment of the present invention provides an air conditioner indoor unit, and on the basis of the first embodiment, the air conditioner indoor unit further includes:
the electronic control box 108 is further provided with a first heat sink and a second heat sink. The first heat dissipation opening is communicated with the air duct 104, and the second heat dissipation opening is communicated with the external environment. Thus, the electronic control box 108 is brought into a state of communication with the outside.
Specifically, the electronic control box 108 is communicated to the air duct 104 through a first heat dissipation opening. During the operation of the indoor unit of the air conditioner, the fan 106 operates and can generate negative pressure in the air duct 104; at this time, the air inside the electronic control box 108 enters the air duct 104 through the first heat dissipation opening, and brings the heat inside the electronic control box 108 to the air duct 104, and the heat entering the air duct 104 is discharged along with the airflow. Meanwhile, the external low-temperature air enters the electronic control box 108 through the second heat dissipation port of the fan, so that the internal air pressure of the electronic control box 108 is balanced, and the internal temperature of the electronic control box 108 is further reduced. In this way, a flowing air flow is generated inside the electronic control box 108, and the heat inside the electronic control box 108 is taken away by the flowing air flow, so as to reduce the temperature inside the heat dissipation member 114 and the electronic control box 108.

A fifth embodiment of the present invention provides an air conditioner indoor unit, and on the basis of the first embodiment, further:
a gap is formed between the notch 110 and the heat dissipation member 114, and the electronic control box 108 is further provided with a second heat dissipation opening. Thus, the electronic control box 108 is brought into a state of communication with the outside.
Specifically, the gap 110 and the heat sink 114 have a gap (not shown), and the electronic control box 108 is connected to the air duct 104 through the gap. During the operation of the indoor unit of the air conditioner, the fan 106 operates and can generate negative pressure in the air duct 104; at this time, air inside the electronic control box 108 enters the air duct 104 through the gap, and heat inside the electronic control box 108 is carried to the air duct 104, and the heat entering the air duct 104 is exhausted along with the airflow. Meanwhile, the external low-temperature air enters the electronic control box 108 through the second heat dissipation port of the fan, so that the internal air pressure of the electronic control box 108 is balanced, and the internal temperature of the electronic control box 108 is further reduced. In this way, a flowing air flow is generated inside the electronic control box 108, and the heat inside the electronic control box 108 is taken away by the flowing air flow, so as to reduce the temperature inside the heat dissipation member 114 and the electronic control box 108.
Therefore, the indoor unit of an air conditioner provided in this embodiment may reduce the heat dissipation efficiency of the heat dissipation member 114 itself by disposing at least a portion of the heat dissipation member 114 in the air duct 104; the heat dissipation efficiency of the heat dissipation member 114 itself can be reduced by the airflow flowing in the air duct 104, so that the heat dissipation efficiency of the heat dissipation member 114 is greatly improved, and the service life of the electric control component 112 in the electric control box 108 is ensured.
A sixth embodiment of the present invention provides an air conditioner indoor unit, and on the basis of the first embodiment, further:
as shown in fig. 1 and 2, the electronic control box 108 includes a box body 116 and a cover 118 that cooperate with each other. The cartridge body 116 is mounted on the housing 102, and the gap 110 is provided in the cartridge body 116 to ensure that the inner space of the cartridge body 116 communicates with the outside. The electrical control 112 is mounted to the cartridge body 116, and the heat sink 114 is also disposed to the cartridge body 116 and ensures that some or all of the heat sink 114 is positioned within the air chute 104 through the gap 110. The cover 118 covers the box body 116 to protect the electronic control unit 112 and the heat sink 114 inside the box body 116.
In this embodiment, further, as shown in fig. 4, the indoor unit of an air conditioner further includes a fastening member 120. The fastener 120 is inserted into the heat sink 114 and screwed to the electronic control box 108, so that the heat sink 114 is stably mounted in the electronic control box 108, and the mounting stability of the heat sink 114 is ensured.

Wherein, the supporting member 122 is disposed on a first side of the heat dissipating member 114 facing the inside of the electronic control box 108, and the fastening member 120 is sequentially disposed through the supporting member 122 and the heat dissipating member 114. In this way, the heat sink 114 can be isolated from the side of the electronic control box 108 by the support 122, and the heat of the heat sink 114 can be prevented from being conducted to the box body 116.
Further, when the electronic control box 108 is sealed with the sealing member 124, the supporting member 122 is disposed at the second side of the heat sink 114 facing the air duct 104, and the fastening member 120 is sequentially inserted through the heat sink 114 and the sealing member 124.
On the basis of the first to sixth embodiments, as shown in fig. 4, the heat dissipation member 114 may be a part located in the electronic control box 108 and another part located in the air duct 104, and the part of the heat dissipation member 114 located in the electronic control box 108 is ensured to be in contact with the electronic control 112. In this way, heat inside the electronic control box 108 can be circulated to the heat sink 114 and transferred to the portion of the heat sink 114 outside the electronic control box 108. That is, the heat dissipation member 114 can conduct the heat inside the electronic control box 108 and the heat generated by the electrical control 112 to the outside of the electronic control box 108, so as to achieve the heat dissipation and cooling of the electronic control box 108 and the electrical control 112.
In addition to the first to sixth embodiments, the heat dissipation member 114 may be entirely located in the air duct 104 (not shown). In this way, the contact area between the heat sink 114 and the air in the air duct 104 can be enlarged, and the heat dissipation effect of the heat sink 114 itself can be further improved, so as to achieve the heat dissipation and cooling of the electronic control box 108 and the electronic control 112.
On the basis of the first to sixth embodiments, as shown in fig. 3 and 4, the heat dissipation member 114 is further provided with a heat dissipation notch 126. The heat dissipation notch 126 can increase the heat dissipation area of the heat dissipation member 114. The heat dissipation notch 126 is disposed to penetrate the heat dissipation member 114 along the flow passing direction of the air duct 104. Thus, inside the air duct 104, the flowing air flow not only contacts with the surface of the heat dissipation member 114 for heat exchange, but also flows through the heat dissipation notch 126 for heat exchange with the wall of the heat dissipation notch 126 for contact, so as to increase the contact area between the heat dissipation member 114 and the air flow, ensure the heat dissipation efficiency of the heat dissipation member 114, and further improve the heat dissipation and cooling effects of the electric control box 108 and the electric control member 112.

The electronic control box 108 is arranged in the housing 102, the electronic control box 108 is provided with a first heat dissipation port 128 and a second heat dissipation port 130 which are communicated, the interior of the electronic control box 108 is communicated with the air duct 104 through the first heat dissipation port 128, and the interior of the electronic control box 108 is communicated with the external environment through the second heat dissipation port 130; the electrical controls 112 are disposed within the electrical control box 108.
In particular, in the use process of the indoor unit of the air conditioner, the electrical control 112 generates heat, the temperature inside the electrical control box 108 rises, and the high temperature can easily cause damage to the electrical control 112 and affect the service life of the electrical control 112. Therefore, in the present invention, the electronic control box 108 is communicated with the air duct 104 through the first heat dissipation opening 128, and the electronic control box 108 is communicated with the external environment through the second heat dissipation opening 130.
Therefore, in the use process of the indoor unit of the air conditioner, negative pressure is formed in the air duct 104 due to air flowing in the air duct 104, at this time, air inside the electronic control box 108 enters the air duct 104 through the first heat dissipation opening 128, heat in the electronic control box 108 is brought to the air duct 104, and the heat entering the air duct 104 is discharged along with air flow. Meanwhile, the external low-temperature air enters the electronic control box 108 through the second heat dissipation opening 130, so as to ensure the air pressure in the electronic control box 108 to be balanced, and further reduce the temperature inside the electronic control box 108. In this way, a flowing air flow is generated inside the electronic control box 108, and the heat inside the electronic control box 108 is taken away by the flowing air flow, so as to reduce the temperature inside the heat dissipation member 114 and the electronic control box 108.
Therefore, the utility model can utilize the airflow flowing in the air duct 104 to realize the high-efficiency cooling of the electric control part 112 and the electric control box 108, thereby greatly improving the heat dissipation effect of the electric control part 112 and the electric control box 108, ensuring the use environment of the electric control part 112 and ensuring the service life of the electric control part 112 and the whole air-conditioning indoor unit.
