A washing machine comprises a housing including a main inlet on a front surface thereof, a main washing unit disposed in the housing, a main door opening and closing the inlet, and a sub-washing unit disposed in the main door and provided with a pulsator. A large amount of laundry can be washed through the main washing unit and a small amount of laundry can be washed through the sub-washing unit, so that washing can be efficiently performed according to the amount of laundry.

Drum washing machine

A washing machine includes a tub; a drum rotatably disposed inside the tub; and an ultrasound generator configured to emit ultrasonic waves to washing water loaded in the drum, and to generate bubbles. The ultrasound generator applies ultrasonic energy to the washing water to cause chaotic oscillation of the bubbles.

A method to manufacture a carbon fiber electrode comprises synthesizing polyamic acid (PAA) as a polyimide (PI) precursor from pryomellitic dian hydride (PMDA) and oxydianiline (ODA) as monomers and triethylamine (TEA) as a catalyst, adding dimethylformamide (DMF) to the polyamic acid (PAA) solution to prepare a spinning solution and subjecting the spinning solution to electrostatic spinning at a high voltage to obtain a PAA nanofiber paper, converting the PAA nanofiber paper into a polyimide (PI) nanofiber paper by heating, and converting the polyimide (PI) nanofiber paper into a carbon nanofiber (CNF) paper by heating under an Ar atmosphere. Also, the method to manufacture a polyimide carbon nanofiber electrode and/or a carbon nanotube composite electrode may utilize carbon nanofibers having diameters that are lessened by optimizing electrostatic spinning in order to improve spinnability.

A deionization apparatus for regenerating electrodes using vibration and a method of controlling the same. The deionization apparatus includes electrodes to which ions contained in a fluid are absorbed, and a piezoelectric element to separate the ions absorbed to the electrodes by vibration. Since the ions absorbed to the electrodes are separated using mechanical energy generated by the piezoelectric element, it may be possible to more rapidly perform regeneration of the electrodes.

Deionization apparatus and method of controlling the same

An electrode module capable of improving productivity by integrally bonding a current collector and a pair of electrodes using a protective film. The current collector receives power from an external power supply, and the pair of electrodes receives power from the current collector. The current collector and electrodes are integrally bonded by thermocompression using a protective film.
