Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: A clothes care apparatus according to a disclosed embodiment includes: a chamber; an upper fan provided on an upper side of the chamber and configured to move air in a lower side direction of the chamber; a lower fan provided on a lower side of the chamber and configured to move air in an upper side direction of the chamber; a first motor configured to rotate the lower fan; a steam generating device configured to generate steam by heating water; and a controller configured to control on/off of the steam generating device and the first motor and turn on the steam generating device in a first section for supplying the generated steam into the chamber and turn on the first motor in a second section for dispersing the steam by the air moving into the chamber.

Abstract: A formaldehyde detecting apparatus includes a formaldehyde sensor configured to measure concentration of formaldehyde in air; a printed circuit board on which the formaldehyde sensor is disposed, the printed circuit board including a signal processor configured to process a signal output from the formaldehyde sensor; a fixing member disposed on the printed circuit board, the fixing member configured to fix the formaldehyde sensor, wherein the fixing member prevents the formaldehyde sensor from oscillating with respect to the printed circuit board by external vibration; and a power supply configured to supply a voltage capable of stabilizing an output signal to the signal processor.

Abstract: An air conditioner includes an indoor unit, an outdoor unit including an outdoor fan, a sensor unit mounted at an upper portion of the outdoor unit to sense snow piled up on the outdoor unit, and a control unit to determine whether snow is piled up or not based on an output from the sensor unit and control an operation of the outdoor fan to remove snow when snow is piled up based on the determination. The sensor unit includes a photo sensor and a temperature sensor.

Abstract: A water level sensing apparatus which more precisely senses a level of supplied water, a water supply hose and a washing machine having the same is provided. The water level sensing apparatus includes a main body provided with an inner wall and an outer wall and filled with water supplied to the inside of the inner wall, a plurality of electrodes inserted between the inner wall and the outer wall to be opposite to each other, and a micro-computer to judge a water level in the main body through variation of a capacitance value of the plurality of electrodes. Therethrough, the water level sensing apparatus 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.
