    Abstract: An apparatus for detecting an oil level and a method for controlling the same, an apparatus for detecting oil flow and a method for controlling the same, and a method for controlling oil return using the detected oil level and the detected oil flow are disclosed. The level of oil stored in a compressor is measured at two or more positions. The frequency comparison scheme using two electrodes can correctly detect the level of oil stored in the compressor, a refrigerant state, and the level of mixed oils, and can determine an internal state of the compressor and a normal or abnormal state of the oil return system, such that the oil return control can be actively controlled. The flow of oil in the oil return pipe is detected so as to determine whether the oil is normally supplied in real time, such that a malfunction of the compressor is prevented and a valve state can be checked. The level of oil stored in the compressor is adjusted not only using the oil level detection result but also the oil flow detection result, and the oil return operation can be controlled.

    Abstract: A refrigerator having a carbonated water production device, according to one concept of the present invention, comprises: a pressure regulator for adjusting and emitting the pressure of carbon dioxide emitted from a carbon dioxide cylinder; a solenoid switch valve for controlling the supply of the carbon dioxide discharged from the pressure regulator to a carbonated water tank; a connection channel for connecting the pressure regulator and the solenoid switch valve; and a relief valve arranged in the connection channel so as to discharge the carbon dioxide of the connection channel to the atmosphere if the pressure of the carbon dioxide of the connection channel is greater than a predetermined pressure limit. Thus, the pressure of the carbon dioxide of the connection channel is capable of being maintained at a predetermined pressure limit or less, and solenoid malfunction can be prevented so as to improve reliability and stability of a system.

    Abstract: Disclosed herein are a turbidity sensor and a control method thereof, and more particularly, to a turbidity sensor capable of measuring turbidity of water including a liquid detergent as well as water including a powdered detergent and a control method thereof. The turbidity sensor includes a first light emitting unit emitting visible light, a first light receiving unit disposed opposite to the first light emitting unit at a position spaced apart from the first light emitting unit and receiving visible light emitted from the first light emitting unit, and a control unit determining a turbidity of a solution according to a ratio between the amount of visible light emitted from the first light emitting unit and the amount of visible light received by the first light receiving unit. According to the turbidity sensor and control method thereof, turbidity of the solution by the first and second particles is accurately measured.
