摘要:
A heating cooker including an infrared ray detection device is disclosed. The heating cooker includes a body (10), an inner case (40) disposed within the body, and provided therein with a cooking chamber (20) to cook food, a detection hole (40a) formed at one side wall of the inner case (40), to allow an infrared ray generated in the cooking chamber (20) to exit outwardly from the cooking chamber (20), a path change unit (130) disposed in the vicinity of the detection hole (40a), to change a path of the infrared ray passing through the detection hole, and an infrared sensor (120) disposed to be spaced apart from the path change unit (130), to receive the infrared ray, the path of which has been changed. The path change unit (130) is rotatable to enable the infrared sensor (120) to receive infrared rays having different paths while being generated in different regions in the cooking chamber.

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 (40) includes a first light emitting unit (41) emitting visible light, a first light receiving unit (47) 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 (45) 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.

Disclosed herein are a dryer (1) and a drying method of the same. The dryer includes a condensing unit (50) to change water vapor evaporated from a drying object into condensate water by cooling, a condensate water storage container (200) in which the condensate water is stored, a water level sensing device (240,250) to detect a level of the stored condensate water, and a microcomputer to calculate a change rate of condensation or of the condensate water level based on the detected water level and to determine a value of dryness of the drying object. The dryer effectively performs a drying operation based on the accurately detected value of dryness of the drying object.

摘要:
A water level sensing apparatus (162; 262) which more precisely senses a level of supplied water, a water supply hose (63) and a washing machine having the same is provided. The water level sensing apparatus includes a main body (169) provided with an inner wall (166) and an outer wall (165) and filled with water supplied to the inside of the inner wall, a plurality of electrodes (167) inserted between the inner wall (166) and the outer wall (165) to be opposite to each other, and a micro-computer (160) to judge a water level in the main body (169) through variation of a capacitance value of the plurality of electrodes (167). Therethrough, the water level sensing apparatus (162; 262) more directly measures a water level, as compared to the conventional water level sensing apparatus, thus improving precision in water level measurement. Thereby, the water level sensing apparatus prevents unnecessary water supply and reduces energy consumption.
