Abstract:
An evaporative humidifier including a water bucket, a tub configured to accommodate water introduced from the water bucket, a humidifying element configured to execute humidification by receiving the water accommodated in the tub and evaporating the received water, and an ultraviolet ray emitting part provided on the tub to emit ultraviolet rays to the tub.
Abstract:
A mix-type catalyst filter which has a variety of pore sizes and thus improves efficiency of catalysts and a method for manufacturing the same. The method includes spinning nanofibers, heating the nanofibers, crushing the nanofibers to form chip-type nanofibers, mixing the chip-type nanofibers with particulate catalysts to obtain a mix-type catalyst and heating the mix-type catalyst.
Abstract:
A water softening apparatus having an improved structure to provide a function of an air brake, a dishwasher including the same and a control method thereof, the water softening apparatus having an air brake assembly and a regeneration tank and configured to soften wash water being supplied from a tub, wherein the air brake assembly including a water supply valve allowing wash water to be introduced therethrough, an ion exchange tank to accommodate an ion exchange resin therein, and a plurality of valves installed on a first path allowing wash water being introduced through the water supply valve to flow toward the ion exchange tank, wherein the regeneration tank is connected to the air brake assembly and accommodates regeneration material configured to purify the ion exchange resin.
