A dishwasher includes a filter member having a handle integrally provided at an upper cover of the filter member. The filter member is accommodated in a filter accommodation space of a filter housing, where a movement space of the filter member is larger than the filter member, thereby preventing damage to the filter material or a fall of contaminants into the filter housing effectively, during withdrawal and insertion of the filter member. A separation space defined between the filter housing and the upper cover of the filter member is closed by a gasket, in the state where the filter member is disposed in the filter housing completely, thereby preventing the flow of non-filtered air into the filter housing effectively.

A dishwasher includes a tub in which dishes are stored, a base disposed below the tub, a dry air supplier configured to spray air to the tub, and a cover disposed to expose the dry air supplier through an opening formed in a bottom surface of the base and configured to close the opening by being coupled to the base.

A method controls a dishwasher including a tub configured to receive objects to be washed, a drying device configured to receive wet air from the tub and to discharge the wet air to an outside of the dishwasher, and a dry air supplier including a heating part and being configured to supply heated air to the tub. The method includes preheating the drying device by introducing dry air from the outside to the drying device before a first preset time from a start point of a drying operation, performing the drying operation at the start point, wherein the wet air is discharged from the tub during the drying operation, and cooling the dry air supplier by stopping operation of the heating part before a second preset time from an end time point of the drying operation.

A dishwasher includes a tub, a door coupled to a front of the tub, and a drying device disposed at the door and configured to dry an inside of the tub. The drying device includes a bracket that defines a space configured to receive the wet air and the dry air, an impeller coupled to the bracket and configured to cause the wet air and the dry air to be mixed, where the impeller is configured to generate a flow of the mixed air. The drying device further includes a cover coupled to the bracket, and an air guide disposed between the bracket and the cover and configured to guide the flow of the mixed air into the impeller. The impeller is rotatably coupled to the air guide.

A dishwasher includes a tub that defines a washing space configured to accommodate objects to be washed, a door coupled to a front of the tub, and a drying device disposed at the door and configured to guide (i) wet air discharged from the inside of the tub and (ii) ambient air introduced from an outside of the tub. The drying device includes a bracket that defines a space configured to receive the wet air and the ambient air, where the bracket defines a first inlet that is in fluid communication with the outside and configured to receive the ambient air from the outside. The drying device further includes a cover coupled to the bracket and an impeller coupled to the bracket and configured to cause the wet air and the ambient air to be mixed, where the impeller is configured to generate a flow of the mixed air.

A dishwasher includes a tub forming a washing chamber and a blowing unit that blows air into the tub, where the blowing unit includes a housing having a discharge port, a blowing fan disposed inside the housing, and a valve disposed between the blowing fan and the discharge port to prevent moisture from being introduced into the blowing fan, and the valve is rotated from a closed position to an open position by blowing of the blowing fan and return to the closed position again by an own weight thereof.

In one aspect, the present disclosure is directed to devices and methods for sterilizing objects using HOCl (hypochlorous acid). A variety of objects may be sterilized, including cups, plates, utensils, toys, medical equipment, etc., in various embodiments. In one set of embodiments, chloride ions (Cl.sup.−) in water may be reacted using an electric current to produce HOCl. In some cases, there may be sufficient Cl.sup.− in the water such that another source of CF is not required; for example, the water may be tap water containing some Cl.sup.−. In some cases, the water may be acidified to facilitate the production of HOCl, for example, by introducing CO.sub.2 into the water. The production of HOCl may occur relatively quickly, e.g., within a few minutes. This may allow devices to produce water that can be used to sterilize objects quickly and simply.
