Benefits of technology

[0014]According to a nozzle structure of a dish washer of the present invention, the check valve can be easily and simply assembled and installed into the upper nozzle.
[0015]Further, the check valve can have simple structure owing to the nozzle structure, thereby reducing the manufacturing cost of the check valve.
[0016]Furthermore, though the check valve has simple structure, it can prevent leakage of washing water more securely.

Problems solved by technology

However, the flap, the hinge, and the support structure are separately fabricated and assembled into the upper nozzle, thereby complicating the assembly process.
Further, the manufacturing cost for the check valve increases.

Abstract

A nozzle structure of a dish washer is provided. In the nozzle structure, a nozzle holder is provided, a gasket unit is mounted on an end of the nozzle holder and it includes at least one inlet port, a flap support unit is protruded from a front of the gasket unit, and a check valve flap is rotatably coupled to the flap support unit.

Description

TECHNICAL FIELD[0001]The present invention relates to a dish washer, and more particularly, to a nozzle structure of a dish washer that is designed to prevent backflow when water is supplied to a nozzle from a water guide.BACKGROUND ART[0002]Generally, a dish washer is one of electronic appliances, which can wash dishes by removing garbage from the dishes using water sprayed through a spraying nozzle from a sump installed under a tub.[0003]A typical dish washer includes a tub, a sump installed under the tub, a water guide connected to the sump, and an upper nozzle detachably coupled to the water guide from a center of the tub. The upper nozzle is located under a rack of the dish washer. The upper nozzle is detached from the water guide when the rack is extended outwardly, and it is coupled to the water guide again when the rack is retracted inwardly. When a door is closed after the rack is retracted, the rack is stably kept in the retracted position by the door, and the upper nozzle...
