Abstract: An electric control box is provided. The electric control box includes a box body, a circuit board, and a heat sink. The box body has a chamber, and an air inlet and an air outlet that are in communication with the chamber. The chamber has an air duct, and the air inlet and the air outlet are in communication with each other via the air duct. The box body is configured to allow air to be introduced into the air duct from the air inlet and to flow out of the air outlet. The circuit board is disposed in the chamber. The heat sink is disposed at the circuit board and located in the air duct.

Abstract: A motor mounting structure includes a motor, a first support member, and a second support member. The first support member and the second support member are both disposed at the motor and configured to be fixed. The first support member and the second support member are different from each other.

Abstract: A drain pan and an air conditioner are provided. The drain pan includes a plastic member and a foaming member, an air outlet near the edge of the plastic member, and a water receiving sink. An air inlet is provided in the middle part of the plastic member. The water receiving sink is arranged between the air inlet and the air outlet and surrounds the air inlet. The air outlet continuously surrounds at least part of the outer edge of the water receiving sink. Multiple supporting grilles are arranged inside the air outlet. The supporting grilles are distributed at intervals in an extension direction of the air outlet. The foaming member and the plastic member at least partially overlap with each other. The foaming member avoids the air inlet and the air outlet.

Abstract: A heat exchanger sealing plate for an air conditioner, an indoor unit and an air conditioner are provided. The indoor unit includes a casing, an air guiding ring, a heat exchanger, a sealing plate and a water pump. The air guiding ring is provided in the casing. The heat exchanger has a first end and a second end, and the heat exchanger is provided in the casing and surrounds the air guiding ring. The sealing plate is provided in the casing, the sealing plate has a first connecting portion, a second connecting portion and a water pump mounting portion. The first connecting portion and the second connecting portion are connected to the heat exchanger, in order for the sealing plate to close a gap between the first end and the second end of the heat exchanger. The water pump is mounted on the water pump mounting portion.

Abstract: An air conditioner indoor unit includes a housing and a blower assembly. The housing has an air supply duct and an electric control chamber. The electric control chamber is provided with a main control module. The blower assembly includes an electric motor, a blower, and a drive module. The blower is disposed in the air supply duct for driving an airflow. The electric motor is in transmission connection with the fan. The drive module is electrically connected to the electric motor.
