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: 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.

Abstract: An air conditioner indoor unit includes a housing and a blower assembly. The housing is provided with an air supply duct and an electric control chamber. The electric control chamber is spaced apart from the air supply duct. The blower assembly is disposed in the air supply duct for driving an airflow. The electric control chamber is provided with a drive module. The drive module is electrically connected to the blower assembly. The electric control chamber has a vent for heat dissipation of the drive module.

Abstract: Provided are a filtration device and an air conditioner. The filtration device is applied in the air conditioner, and includes a frame and a filtration structure. The filtration structure is detachably connected to the frame by a first buckle. The frame is configured to be mounted at a housing of the air conditioner. In the filtration device according to the present disclosure, the filtration structure is detachably connected to the frame by the first buckle. After the filtration device is used for a period of time, a user can disassemble the filtration structure for cleaning, maintenance, or replacement.

Abstract: An air conditioner includes: a housing having a fan cavity and a heat exchange cavity in communication with each other; an electric control box disposed in the housing and in communication with the heat exchange cavity and the fan cavity; an electric control disposed in the electric control box; and a fan assembly disposed in the fan cavity and configured to supply air to the heat exchange cavity and dissipate heat of the electric control box. A circulating flow path is formed inside the air conditioner, to allow an airflow in the fan cavity flowing into the heat exchange cavity to at least partially flow into the electric control box and flow back to the fan cavity through the electric control box.
