An ink-jet image forming apparatus. The ink-jet image forming apparatus includes a print head having a plurality of nozzles to eject ink, an ink tank to store the ink, an ink supply passage to supply the ink in the ink tank to the print head, an ink return passage to return the ink in the print head to the ink tank, a regulator mounted in the ink supply passage to regulate ink flow supplied to the print head, a shut-off valve mounted in the ink supply passage, between the ink tank and the regulator, to intercept ink flow supplied to the regulator, and an ink pump mounted in the ink return passage to forcedly flow the ink in the ink return passage. The ink pump is configured to be driven in forward and reverse directions so as to change an ink flow direction. Since the shut-off valve intercepts forcedly the ink flow in the ink supply passage, the ink in the ink tank is prevented from flowing abnormally to the print head and leaking from the print head.

Ink-jet image forming apparatus and method of controlling ink flow

An image forming apparatus including a body, a print head including a nozzle part having a length corresponding to a width of a printing medium, and a regulator provided separately from the print head and mounted to the body, the regulator serves to adjust a negative pressure of ink which is to be supplied into the print head.

A washing machine comprising a tub, a water supply unit for supplying water to the tub and a silver solution supply device for supplying a silver solution to the tub, wherein the silver solution supply device includes a housing provided with an inlet and an outlet, a water feed unit for connecting the inlet of the housing and the water supply unit of the washing machine, two silver members installed in the housing and ionized by the electrolysis, and a current speed reduction member positioned between an end of the silver member located at the outlet and the outlet of the housing. The current speed reduction member reduces the current speed of the wash water supplied to the silver solution supply device and changes the current of the wash water, thereby allowing the silver members to be sufficiently ionized and providing sufficient antibiotic and bactericidal effects.

Washing machine provided with silver solution supply device

A washing machine includes a colloidal silver maker and a detergent feeder which are integrated with each other, thus enhancing assembility and reliability of the washing machine. The colloidal silver maker includes a silver ion casing, a lid, and a pair of silver plates. An outlet pipe and a connecting part are provided on predetermined portions of the silver ion casing. The outlet pipe is integrated with an inlet of the detergent feeder, and the connecting part integrally connects the colloidal silver maker to the detergent feeder. Thus, the colloidal silver maker is integrated with the detergent feeder while the silver ion casing of the colloidal silver maker communicating with the detergent feeder. The silver plates are placed in the silver ion casing while being supported by the lid. Further, at least one spacing projection is upwardly projected from a bottom of the silver ion casing to be provided between the silver plates.

Clothes washing machine

A washing machine includes a housing having a top opening, and a spin basket disposed in the housing. A door is mounted on the housing for opening and closing the top opening. A motor-actuated door opening/closing mechanism is provided for opening and closing the door, the mechanism being actuated by a foot pedal mounted at a lower portion of the housing. By pivoting the foot pedal, an electric signal is generated for actuating a motor of the door opening/closing mechanism.
