Patent number: 12209799Abstract: A control method for a refrigerator and a refrigerator are provided. The refrigerator includes a compartment, an evaporator, and a heating module. The method includes: acquiring a current temperature of the compartment; and adjusting an operating power of the heating module according to the current temperature, so that the heating module heats the compartment to a target temperature according to the operating power, where different temperature ranges correspond to different operating powers.Type: GrantFiled: March 15, 2021Date of Patent: January 28, 2025Assignee: BSH Hausgeraete GmbHInventors: Yong Tian, Qiwu Zhu, Weizhong Zhu

Publication number: 20240318892Abstract: A refrigerator and an anti-condensation method for the refrigerator. The refrigerator includes a first storage compartment, a second storage compartment adjacent the first storage compartment, a separation wall separating the first storage compartment and the second storage compartment, and a heater in the separation wall. The first storage compartment is adapted to be set at a refrigerating temperature, and the second storage compartment is adapted to be set at a freezing temperature. In the anti-condensation method, the heater is controlled to work in an anti-condensation mode when a refrigeration system stops cooling the first storage compartment, to heat a surface of the separation wall facing the first storage compartment, which can significantly reduce the probability of condensation on the surface and is beneficial to reduce the impact of the working of the heater on the refrigeration system.Type: ApplicationFiled: July 7, 2022Publication date: September 26, 2024Inventors: Xiangyu Liu, Yong Tian, Qiwu Zhu, Weizhong Zhu

Patent number: 8511102Abstract: A method for defrost control of a refrigerator having a refrigeration and defrost system that includes a compressor, an evaporator, an evaporator fan and a heater. The refrigerator also has a control system to control the operation of the refrigerator. The method includes stopping the compressor operation; starting a defrost process; starting the heater; maintaining a start state over a preset period of time; closing off the heater; and starting the compressor. After starting the compressor and before the evaporator fan is started to perform the refrigeration operation, the evaporator fan is operated at least once briefly and intermittently.Type: GrantFiled: April 17, 2009Date of Patent: August 20, 2013Assignee: BSH Bosch und Siemens Hausgeraete GmbHInventors: Junhong Feng, Xiaotian Zhou, Qiwu Zhu, Weizhong Zhu
