Patent number: 10969163Abstract: The present invention discloses a refrigerator and a humidity control method for the same. The refrigerator comprises a humidity controller to controllably maintain moisture and/or perform humidification. The humidity controller is configured to: set a target humidity value, measure an actual relative humidity value of a target space, and calculate a target water replenishing mass W based on a difference between the two values and a current temperature of the target space; measure and calculate a water replenishing time T, and adjust the humidity controller so as to maintain its maximum humidifying rate Vmax within the time T to achieve the humidification purpose; and adjust the humidity controller so as to maintain a humidifying rate consistent with a water vapor loss rate in the target space to achieve the moisture maintaining purpose.Type: GrantFiled: June 17, 2016Date of Patent: April 6, 2021Assignee: QINGDAO HAIER JOINT STOCK CO., LTD.Inventors: Riyong Lu, Bin Fei, Xueli Cheng, Xiaodong Zhou, Xiaobing Zhu

Patent number: 10612837Abstract: There is provided an airtight box, comprising a box body and a cover covering the box body to close the box body tightly. The box body is provided with a receiving chamber with an opening which opens upwards and two side walls respectively located on both sides of the receiving chamber. A sliding groove extending longitudinally is provided on an outer side of each side wall. The airtight box is further provided with an opening and locking mechanism slidably connecting the cover and the box body. The opening and locking mechanism is provided with a pushing member slidably fixed in the sliding groove and a connecting rod rotatably fixed on the pushing member and mounted inside the cover. The connecting rod, under an action of the pushing member, presses upwards and drives the cover backwards to expose the receiving chamber to the outside.Type: GrantFiled: June 17, 2016Date of Patent: April 7, 2020Assignee: QINGDAO HAIER JOINT STOCK CO., LTD.Inventors: Bin Fei, Riyong Lu, Jinlin Liu, Xiaodong Zhou

Publication number: 20180209747Abstract: A heat conducting plate and a method for producing a plate body thereof. The heat conducting plate comprises an integrally formed plate body. The plate body comprises a front surface, and several capillary tube cavities formed in the plate body and allowing flow of a heat exchange medium. Each capillary tube cavity extends along a first direction parallel to the front surface, and a micro-tooth structure is provided on the inner wall of each capillary tube cavity. The heat exchange medium may flow in the capillary tube cavities along the first direction. By means of the plate body and the capillary tube cavities, the temperature homogenizing effect and heat exchange efficiency of the heat conducting plate are significantly improved; by providing the micro-tooth structure, the heat exchange medium may form a capillary phenomenon, thereby improving the heat exchange efficiency.Type: ApplicationFiled: June 17, 2016Publication date: July 26, 2018Inventors: BIN FEI, DENGQIANG LI, RIYONG LU, XIAOBING ZHU

Publication number: 20180184693Abstract: A method for controlling the concentration of a gas in a crisper drawer (100): by capturing the concentration of a freshness-preserving gas in a storage chamber (10) and comparing with a preset threshold, determining whether to feed the freshness-preserving gas into the storage chamber (10), or employing a timed feeding method to control whether to feed the freshness-preserving gas into the storage chamber (10). The method selectively feeds the fresh-preserving gas into the storage chamber (10), thus controlling the concentration of the freshness-preserving gas in the storage chamber (10) to be kept above a target concentration, significantly extending the time during which food is kept fresh, and at the same time, taking into consideration the economy of using the freshness-preserving gas.Type: ApplicationFiled: June 17, 2016Publication date: July 5, 2018Inventors: RIYONG LU, BIN FEI, JINLIN LIU, ZHUQING LIU
