Benefits of technology

The present invention provides a dishwasher with several technical benefits. Firstly, it prevents wash water from flowing into a steam path when steam is not sprayed, by using a steam valve with an actuator and a valve cap, which closes the steam path. Secondly, it effectively opens or closes the steam inlet using a valve cap moved by an actuator. Thirdly, it protects vulnerable electronic components from damage caused by moisture and other foreign materials, preventing malfunctions and damage to the dishwasher's steam valve.

Problems solved by technology

However, this is problematic in that the valve is not completely opened or closed when the pressure of the wash water is not sufficient, so that some wash water may flow into the steam path, thereby causing a pressure loss of the wash water conveyed by the spray arm.

Abstract

A dishwasher is proposed. The dishwasher includes a case accommodating a cleaning target, a sump connected to an interior of the case to collect wash water, a wash pump into which the wash water collected in the sump flows and which generates steam, a steam nozzle spraying the steam, generated in the wash pump, into the case, and a steam valve disposed on a steam path connecting an outlet of the wash pump and the steam nozzle and including an actuator and a valve cap driven by the actuator to open or close the steam path.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a dishwasher including a steam valve.BACKGROUND ART[0002]A dishwasher is a home appliance that washes dishes or cooking utensils, etc. (hereinafter referred to as a ‘cleaning target’) to remove waste such as food residues therefrom by high-pressure wash water sprayed from a spray arm.[0003]The dishwasher washes the cleaning target using heated wash water or performs a washing operation or a sterilizing operation by supplying steam to the cleaning target. A structure where a heater is installed in a wash pump to efficiently generate steam has been proposed. In addition, a structure where a steam nozzle for spraying steam is disposed on a lower end of a door so that steam is efficiently applied to the cleaning target has been proposed.[0004]Such a dishwasher requires a steam valve which closes a steam path so that wash water does not flow into the steam nozzle when wash water is sprayed through a spray arm, and opens the steam pat...
