摘要:
A filter device may include a filter unit including a first electrode and a second electrode that are arranged so as to be spaced apart and opposite to each other. At least one of the first and second electrodes may include an electrode material layer that is electrically conductive. The electrode material layer may include a metal-adsorbing material (metal adsorbent). A voltage applier for applying voltage to the first electrode and the second electrode for a desired amount of time based on the conditions after operation of the filter unit, and a method for driving the same.
摘要:
A filter unit may include a water permeable first electrode (12), a second electrode (14) arranged so as to be spaced apart from and opposite to the first electrode (12), and a non-water permeable separator (13) that is positioned between the first electrode (12) and the second electrode (14). The first electrode (12) may include a metal adsorbent (metal-adsorbing material) and thus may adsorb a metal included in the water. At least one of the first electrode (12) and the second electrode (14) may induce a water hydrolysis reaction to produce H + ions to regenerate the metal adsorbent. The filter unit may further include a voltage applier to provide a filter system.

A water purifying filter may include an organic material adsorbent. The organic material adsorbent may include graphite with an interplanar spacing at the c-axis of about 0.3354 nm to 0.34 nm as measured by X-ray diffraction analysis (CuKα). A water purifying system may include the water purifying filter.
摘要:
A washing machine for minimizing damage to laundry and enabling effective washing of the laundry. The washing machine includes a water tub, a drum and a control unit. The drum is installed in the water tub so as to rotate in a forward and/or a reverse direction. The control unit controls the rotation directions and angles of the rotation of the drum to cause an asymmetric swing motion of the drum.

A filter unit (1) may include an electrode structure (10), a fluid-purifying flow path (20), and a pH adjusting chamber (30). The electrode structure (10) may include a cathode (12), a cation exchange membrane (14), an anion exchange membrane (16), and an anode (18) in that order. The fluid-purifying flow path (20) may be at least one of a path in the cathode (12), between the cathode (12) and the cation exchange membrane (14), between the anion exchange membrane (16) and the anode (18), and in the anode (18). The fluid-purifying flow path (20) may include an adsorption function. The pH adjusting chamber (30) may be between the cation exchange membrane (14) and the anion exchange membrane (16). The pH adjusting chamber (30) may be configured to control the pH of the fluid in the fluid-purifying flow path (20).
