Patent number: 11060531Abstract: A heating pump includes a pump body and a driving motor. The pump body includes a pump housing with a water inlet and a water outlet, a heating member fixed in an interior of the pump housing, and an impeller connected with the driving motor. The heating member includes fittings and a heating coiled pipe connected between the fittings and bent into an arc. The impeller is disposed at an upper part of the pump housing, one end of the driving motor is disposed adjacent the impeller, and the heating coiled pipe circles around a radial side portion of part of the driving motor. The heating pump has a rational design and high heat exchange efficiency. The safety auxiliary motor has a low requirement for power. The axial size of the water pump is significantly reduced.Type: GrantFiled: September 22, 2016Date of Patent: July 13, 2021Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Awade Badafem, Shao Peng Mo, Min Li, Jin Jin Wu

Patent number: 10418883Abstract: A cover assembly and a brushed motor are provided. The cover assembly includes a mounting portion and a flow guide portion. The mounting portion defines a first opening through the mounting portion along an axial direction of the motor. The flow guide portion includes a top wall disposed at one end thereof away from the mounting portion along the motor axial direction. The fluid guide portion defines a second opening extending to an inner wall surface of the top wall in the motor axial direction. The first opening and the second opening are in flow communication with each other. The flow guide portion further defines a winding flow passage. The flow passage has an inner inlet in flow communication with the second opening and an outer outlet in flow communication with an outside environment. The present invention facilitates absorption of the motor noise and hence reduction of the output noise.Type: GrantFiled: August 18, 2016Date of Patent: September 17, 2019Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Min Li, Jin Jin Wu, Kok Ang Chong, Cheng Zhuang Zhu

Patent number: 10302098Abstract: A heating pump includes a pump housing with an inlet, an outlet, a heater, an impeller, and a motor for driving the impeller. The impeller is received in the pump housing. The heater includes connecting heads and a main body for generating heat. The main body is bent into an arc. The pump housing includes a cylindrical sidewall extending in an axial direction of the motor and a top plate sealed to an axial opening of the sidewall. The top plate is made of metal. The heater extends through and is fixed to the top plate. The connecting heads extend to an exterior of the pump housing. The main body is located in an interior of the pump housing and in contact with the top plate.Type: GrantFiled: August 6, 2015Date of Patent: May 28, 2019Assignee: JOHNSON ELECTRIC INTERNATIONAL AGInventors: Min Li, Jin Jin Wu, Kok Ang Chong
