Patent number: 11896162Abstract: A blender includes a jar including a blade module to cut an object, a main body to receive the jar and including a motor to rotate the blade module, and a controller disposed inside the main body and configured to operate the motor. The main body further includes an outer case and forming an outer structure of the main body. The outer case includes a touch input portion on an outer surface of the outer case. A touch sensor is disposed on an inner surface of the outer case at a position corresponding to the touch input portion to detect a touch input on the touch input portion. The controller is configured to determine an operation time period of the motor based on the touch input detected by the touch sensor.Type: GrantFiled: October 18, 2021Date of Patent: February 13, 2024Assignee: LG ELECTRONICS INC.Inventors: Namhun Kim, Kyungsoo Hwangbo

Patent number: 11785680Abstract: An induction heating device and a method for sensing a cooking vessel on an induction heating device are provided. The induction heating device may include a controller that converts a resonance waveform generated as current is applied to a sensing coil into a square waveform. The controller may determine whether a cooking vessel placed on the induction heating device has an inductive heating property based on a number of pulses of the converted square waveform.Type: GrantFiled: October 13, 2021Date of Patent: October 10, 2023Assignee: LG ELECTRONICS INC.Inventors: Kyungsoo Hwangbo, Bong Jin Cho

Patent number: 11770881Abstract: A cooking vessel sensor and an induction heating device including a cooking vessel sensor is provided. The cooking vessel sensor may include a cylindrical hollow body having a first receiving space defined therein; a hollow cylindrical magnetic core received in the first space and having a second receiving space defined therein; and a sensing coil wound on an outer face of the side wall by a predetermined number of winding counts. The cylindrical hollow body may have a side wall having a coil outlet defined therein, and the sensing coil may pass though the coil outlet out of the body. The cooking vessel sensor may further include a controller that applies a current to the sensing coil and determines, based on a sensing result of the cooking vessel sensor, whether the cooking vessel is inductive or has an inductive heating property.Type: GrantFiled: September 15, 2021Date of Patent: September 26, 2023Assignee: LG ELECTRONICS INC.Inventors: Kyungsoo Hwangbo, Junbo Byun, Hyeonwoo Seo

Publication number: 20230157486Abstract: Proposed is a blender which detects whether a container lid is closed by transmitting an electrical signal through a transparent film. The blender according to the present disclosure comprises a container body in which food is accommodated; a main body provided under the container body so as to support the container body; the container lid detachably mounted on the upper surface of the container body so as to open and close the upper side of the container body; and a detection system which detects whether the container lid is mounted on the container body, wherein the detection system includes a transparent electrode film configured to have multiple layers so as to guide the flow of electricity. Therefore, the blender has the advantage of preventing an assembly defect without damaging the appearance of the container body formed of a transparent material.Type: ApplicationFiled: May 6, 2021Publication date: May 25, 2023Inventors: Kyungsoo HWANGBO, Mingyu KIM
