Patent number: 12007128Abstract: An outdoor unit for an air conditioner, and an air conditioner are provided. The outdoor unit has a housing and a draught fan. The housing is provided with a first air exchange port and a second air exchange port. The draught fan is arranged in the housing and located between the first air exchange port and the second air exchange port. The draught fan has an electric motor, a first fan, and a second fan. The electric motor has two rotors which rotate independently of each other, and a first output shaft and a second output shaft connected to the two rotors respectively. The first output shaft and the second output shaft are respectively fixedly connected to the first fan and the second fan for driving the first fan and the second fan to rotate independently of each other.Type: GrantFiled: November 4, 2021Date of Patent: June 11, 2024Assignee: MIDEA WELLING MOTOR TECHNOLOGY (SHANGHAI) CO., LTD.Inventors: Ping Li, Yiming Hu, Guyu Wu, Di Wu

Patent number: 11863030Abstract: A motor and a fan are provided. The motor has a stator assembly, two mutually independent rotor assemblies, and two mutually independent rotating shaft assemblies. The stator assembly has a stator core and two groups of mutually independent windings. The rotor assemblies are oppositely and coaxially arranged on two axial sides of the stator assembly and form an axial air gap with the stator assembly. The two rotor assemblies are configured to rotate independently. The two mutually independent rotating shaft assemblies are coaxially connected with the two rotor assemblies, respectively, and protrude in a direction of the same side away from the stator core along the axial direction of the motor.Type: GrantFiled: November 5, 2021Date of Patent: January 2, 2024Assignee: MIDEA WELLING MOTOR TECHNOLOGY (SHANGHAI) CO., LTD.Inventors: Ping Li, Yiming Hu, Guyu Wu, Di Wu, Liming Gong

Publication number: 20220252282Abstract: The present disclosure provides an air conditioner outdoor unit that includes: a motor having first and second output shafts; a first-stage fan blade connected to the first output shaft; a second-stage fan blade connected to the second output shaft. The motor is configured to drive the first-stage and second-stage fan blades to rotate, and rotation directions of the first-stage and second-stage fan blades are opposite. The motor is located between the first-stage and second-stage fan blades, or on the same side of the first-stage and second-stage fan blades. The outdoor unit is provided with a motor, and first-stage and second-stage fan blades, so that the motor drives the first-stage fan blade to rotate through the first output shaft, and drives the second-stage fan blade to rotate in the opposite direction through the second output shaft. By recovering the rotational energy of the airflow, higher wind pressure is achieved.Type: ApplicationFiled: April 28, 2022Publication date: August 11, 2022Inventors: Dongwen ZHAN, Site HU, Jiachao YAN, Longxin ZHANG, Yuefei LI, Qizhen WANG, Guyu WU
