Abstract: The present disclosure relates to an induction heating apparatus and a method of controlling the same. A controller of the induction heating apparatus according to the present disclosure may set an operation mode of an inverter circuit to a half bridge mode when a required power value of a working coil is set to a value less than a reference power value such that a driving frequency of the working coil decreases while an actual power value of the working coil is kept the same as the required power value. Additionally, the controller of the induction heating apparatus may adjust a duty ratio of a switching signal input to a switching element included in the inverter circuit, thereby adjusting the actual power value of the working coil.

Abstract: Disclosed is a construction equipment including: a boom operating unit including a boom, a boom cylinder, and a boom head and rod return solenoids for controlling the extension of the boom by controlling the ascending and descending of the boom cylinder; an arm operating unit comprising an arm and an arm cylinder so as to move the arm by controlling the extension of the arm cylinder; and a control unit for generating a flow path connection signal in at least a part of the boom head and rod return solenoids upon operation of an arm lever in a boom float mode so as to control the boom cylinder.

Abstract: Disclosed is a method of controlling work of an excavator. When a supply flow rate of hydraulic oil which is supplied to a working apparatus by a first pump among first and second pumps driven by the rotational force of the engine is higher than a requirement flow rate required by the working apparatus, the RPM of an engine is reduced, and hydraulic oil pumped by the first and second pumps are supplied to the working apparatus. Accordingly, an energy-saving effect such as a gas mileage of an excavator being reduced is obtained.

Abstract: Provided is a refrigerator configured to improve the structure of an ice-making chamber provided to a refrigerator door, thereby efficiently supplying cool air into the ice-making chamber. The refrigerator includes a main body including a storage chamber, a refrigerator door rotatably coupled to the main body, an ice-making device provided to the refrigerator door and configured to make ice, an ice-making unit provided to the ice-making device and including a cool air introduction part, a freezing core vertically arranged in the ice-making unit and cooled by cool air, and an ice tray configured to receive at least one portion of the freezing core therein, wherein the cool air introduction part is provided on an upper side of the freezing core. Cool air is efficiently introduced into the ice-making chamber, thereby increasing the amount of ice made.

Abstract: An ice making assembly for a refrigerator and a method for controlling the ice making assembly are provided. The ice making assembly and the method of controlling the ice making assembly provides a constant amount of water supply for each ice making cycle regardless of environmental conditions such as the varying water supply pressure of different installation locations. Furthermore, overflowing can be prevented during water supply with the use of a capacitance water level sensor.

Abstract: An ice-making device designed to make and separate ice from an ice tray through a simple process is provided. The ice-making device includes an ice tray defining an ice-making space, a freezing core that is partly received in the ice-making space to make ice at an end thereof, a driving unit moving and rotating the freezing core, and a power transmission unit for transferring power from the driving unit to the freezing core. The power transmission unit including a cam unit rotatably connected to the driving unit and a moving member that moves in vertical and rotational direction by a driving force of a motor transferred by the cam unit.

Abstract: An ice-making device for a refrigerator, which is designed to separate ice through a simple process is provided. The ice-making device for a refrigerator includes an ice tray defining an ice-making space, an ice core member that is partly received in the ice-making space to make ice at an end thereof, a driving unit moving and rotating at least one of the ice tray and the ice core member, and a power transmission unit for transferring power from the driving unit to the ice core member. The ice on the ice core member starts being separated in a state where the ice is spaced apart from an outer surface of the ice tray.

Abstract: An ice making apparatus for a refrigerator, in which an ice bank stores ice and has an opening that discharges ice on its one side. An ejector opens and closes the opening and is rotatably provided at the opening to also eject ice from the ice bank. After completion of an ice discharging operation, a sensor senses a relative position of the ejector against the ice bank and the ejector is controlled to close the opening to the extent necessary.

Abstract: An ice-making device includes a duct through which ice is dispensed and a duct-covering part opening and closing the duct. A sensor part senses whether the duct-covering part closes the duct and a control part controls the duct-covering part to open the duct when the sensor part senses that the duct-covering part fails to close the duct and the duct-covering part has been attempting to close the duct for at least a preset period of time.

Abstract: An ice-making device includes a duct through which ice is dispensed and a duct-covering part opening and closing the duct. When an operation load applied to the duct-covering part while the duct-covering part closes the duct is greater than a preset normal load, the duct-covering part operates to open the duct.

Abstract: Ice making assembly for a refrigerator and a method for controlling the ice making assembly. The ice making assembly and method capable of more effectively providing transparent ice. The ice making assembly and method also capable of preventing water overflow.

Abstract: An ice-making device that includes a duct through which ice is dispensed and a duct-covering part for opening and closing the duct. An ice conveying part conveys the ice dispensed through the duct. A driving speed of the ice conveying part increases for a previously set initial driving time when the dispensing of the ice starts, and the ice conveying part is driven at a previously set target speed when the initial driving time elapses.

Abstract: Disclosed is a refrigerator having a dispenser, including a main body having a cooling chamber and a door for selectively shielding the cooling chamber.
