A water softener is provided not to inject a NaCl solution for regenerating an ion-exchange resin and to supply continuously soft water. A water softener without injecting a NaCl solution in an ion exchanger contains ion exchangers(21A, 21B) including an ion-exchange resin. The ion exchanger contains a first ion exchanger and a second ion exchange unit for softening water and regenerating the ion-exchange resin by turns. Additionally, the water softener contains an acidity water forming unit(22) for supplying acidity water selectively to one of the first ion exchanger and the second ion exchange unit by generating the acidity water in which large amount of cation is included.
Abstract:
A water softener for increasing processing amount is provided to prevent environmental contamination by the Na+ ion, and soften water of the large amount, by including a chamber with a water path. A chamber where the flow channel in which a water path is formed(10). An ion exchange part(10a) in which the ion-exchange resin the chamber is adopted. A negative ion absorbing part(10b) installed to be segmented in one side of the ion exchange part, absorbs the material of the anion state from the ion exchange process part. A positive ion absorbing part(10c) installed in the other side of the ion exchange process part to be segmented with the ion exchange process part, absorbs the material of the positive ion condition from the ion exchange process part. The negative ion absorbing part includes the first base electrode. The first base electrode is arranged to be located with the first net electrode and the material of the negative ion state is flowed in into the negative ion absorbing body when the plus electricity source is applied.
Abstract:
A water softener is provided to apply a magnetic field in an orthogonal direction of an electrode unit to which a positive ion is applied and an electrode unit to which a negative ion is applied in order to improve the speed of ion to the electrode unit, thereby relatively increasing liquid capacity which can be processed within unit time. Hard water is flowed into a chamber(10) and softened hard water is discharged. A plurality of electrode units(20) is stacked in the chamber. Positive and negative voltages are alternately applied to the electrode unit. A magnetic member(30) applies a magnetic field to the hard water flowed into the chamber. The magnetic member is among a plurality of electrode units.
Abstract:
A refrigerator is provided to prevent freezing of a beverage in a supercooling container and to lower a supercooling temperature by transmitting vibration to supercooled water, which is thermodynamically unstable, using a solenoid cell. A refrigerator comprises a body, a supercooling chamber, plural supercooling containers(30), and a solenoid cell. The supercooling chamber is installed in the body to supercool a beverage. The supercooling containers are formed in the supercooling chamber and store the beverage. The solenoid cell transmits vibration to the supercooling containers and has a coil(32) and a power unit(35). The coil is wound in a wall of the supercooling container. The power unit supplies power to the coil.
Abstract:
A dishwasher is provided to move a lower basket upward, using a lifting device having a plurality of links, for taking out dishes which are kept on the lower basket easily. A dishwasher comprises a body, upper and lower baskets(13U,13L), and a lifting device(30). A cleaning tank(11) is arranged in the body. The upper and lower baskets are moved to upper and lower sides of the cleaning tank. The lifting device moves the lower basket upward. The lifting device includes a plurality of links, and stoppers(22). The stoppers are received and projected in/from sides of the cleaning tank to fix the lower basket which is rotated by the links at the upper position. The lifting device includes first four links(31) rotated at front and rear sides in the cleaning tank, a pair of second links(32), and third links(33) hinged with the first links. Supporting projections(13b) are installed at the lower basket. A pair of projections are formed at upper surfaces of the second links to mount the supporting projections. A plurality of wheels(13a) are installed at two sides of the front and two sides of the rear of the lower basket.
Abstract:
A robot cleaner system having a robot cleaner and a docking station is provided to prevent dust flowing into the docking station from the robot cleaner from leaking by forming a protrusion, communicating a dust outlet of the robot cleaner with a dust inlet of the docking station, on the robot cleaner. In a robot cleaner system having a robot cleaner(100) and a docking station(200), the robot cleaner includes a robot body(110) having a dust outlet(114) and the docking station includes a dust inlet(211) and a dust path(240). The dust inlet of the docking station sucks dust stored in the robot cleaner. The dust path of the docking station guides dust sucked through the dust inlet to a dust collecting unit. The robot cleaner is provided with a protrusion(150) protruded from the robot body outwardly so that the protrusion is inserted into the dust inlet of the docking station when the robot cleaner docks with the docking station. The dust outlet and the dust path are communicated with each other by the protrusion.
