Patent number: 10285537Abstract: A grill device for cooking a fluidic food material includes a lower grill plate and an upper grill plate. The lower grill plate includes a lower base wall and a lower surrounding wall that extends upwardly from the lower base wall. The lower base wall has at least one lower inclined surface. The upper grill plate removably covers and is operable to uncover the lower grill plate. The upper grill plate cooperates with the lower grill plate to define a cooking space therebetween, and is formed with an opening through which the fluidic food material is fed into the cooking space. The lower inclined surface is for guiding the fluidic food material to flow smoothly and then fill up the cooking space.Type: GrantFiled: August 18, 2016Date of Patent: May 14, 2019Assignee: Tsann Kuen (Zhangzhou) Enterprise Co., Ltd.Inventors: Yixin Zhan, Dongmei Chen, Wenyu Chang, Xiaoyue Zhu

Publication number: 20180206674Abstract: A cooking device includes a lower grill unit having a lower grill surface, and an upper grill unit cooperating with the lower grill surface to define a cooking space. A support member includes a pivoting end portion pivotally connected to the lower grill unit, and a supporting end portion opposite to the pivoting end portion. The support member is operable to move between a folded state, where the supporting end portion is received in the lower grill unit so that the latter can be horizontally placed on a flat surface, and an unfolded state, where the supporting end portion is pivoted downwardly and forwardly relative to and cooperating with the lower grill unit to obliquely support the cooking device on the flat surface.Type: ApplicationFiled: January 11, 2018Publication date: July 26, 2018Inventors: Dongmei CHEN, Yixin ZHAN

Patent number: 8927165Abstract: A method for controlling relative humidity (RH) of a cathode side of a fuel cell stack in a fuel cell system that includes an RH sensor on a cathode inlet line for providing an RH signal indicative of the RH of cathode inlet air. If the RH sensor is providing a valid RH signal, the RH signal is calculated as an RH average of the cathode inlet air. When the RH sensor is not providing a valid RH signal, the calculated RH average is utilized to control the cathode inlet air RH. If the RH sensor is not providing a valid signal during start-up, then the stack power is temporarily set at an optimum level for a known cathode inlet air RH.Type: GrantFiled: June 28, 2010Date of Patent: January 6, 2015Assignee: GM Global Technology Operations LLCInventors: Dongmei Chen, Victor W. Logan, Matthew C. Kirklin

Patent number: 8616120Abstract: A grilling device with the rotatable lock catch, has a pin module and a rotary shaft joint with two semi-shafts. The upper half shaft of the rotary shaft has a post rod, the lower half shaft of the rotary shaft has a through hole for accommodating the passing in and out of the post rod. The upper end of a supporting shelf of the pin module is disposed with a U-shaped opening for adapting the rotary shaft, two short shafts are respectively disposed by the two sides of the U-shaped opening, two arc-shaped spacing flakes with opposite openings are respectively hinged joint with the corresponding short shafts. A movable ejector pin is disposed on the supporting shelf and along the midline of the U-shaped opening. A pressing board of the middle portion of the ejector pin upward presses the lower portions of the two spacing flakes.Type: GrantFiled: March 4, 2010Date of Patent: December 31, 2013Assignee: Tsann Kuen (Zhangzhou) Enterprise Co., Ltd.Inventor: Dongmei Chen

Patent number: 8326477Abstract: A system and method for providing nearly instantaneous power in a fuel cell vehicle. The method includes monitoring the brake pedal angle and the accelerator pedal angle of the vehicle, and if the vehicle driver is pressing both the brake pedal and the accelerator pedal at the same time and the vehicle is in a drive gear, activating a heel and toe mode. When the heel and toe mode is activated, the speed of a cathode compressor is increased to a predetermined speed set-point, which is higher than the normal compressor speed for the pedal position. Thus, when the vehicle brake is removed, the compressor speed is high enough to provide enough air to the cathode, so that the stack can generate nearly immediate power.Type: GrantFiled: February 26, 2010Date of Patent: December 4, 2012Assignee: GM Global Technology Operations LLCInventors: Tayoung Choi, Dongmei Chen
