Problems solved by technology

However, despite the above devised methods according to the related art, the problem of increasing dishwashing efficiency remains.
Especially in oriental households, where in many cases, the staple food is glutinous rice, the latter is difficult to effectively remove from dishes, exasperating the problem of dishwashing efficiency.
Even the use of hot water to soak food residue cannot completely obviate the above problem.
Also, because soaking requires a prol...

first embodiment

[0069]Alternative embodiments according to the present invention will be described below. Descriptions of like parts already described in the first embodiment shall be deemed included herein, and are therefore omitted herefrom.

second embodiment

[0070]FIG. 5 is a flowchart showing a controlling method of a dishwasher according to the present invention.

[0071]Referring to FIG. 5, after dishes are stored inside the dishwasher, the operation of the dishwasher is begun. Prior to this, water already in the unit undergoes an initial draining in step S11. After the initial draining has been performed, wash liquid is supplied and sprayed towards the dishes through the lower and upper spray arms 14 and 15 and the top spray nozzle 24.

[0072]During the spraying of wash liquid, larger food particles are washed in step S12. This wash cycle, which is not supplied with detergent, washes food residue using only wash liquid, and can therefore be called a pre-wash cycle.

[0073]After the pre-washing in step S12 is completed, steam is supplied into the tub in step S13. The supplying of steam in step S13 is sustained for a predetermined duration, which may extend for a period suitable to completely soak the deposits hardened on the dishes. The ste...

third embodiment

[0084]FIG. 6 is a flowchart showing a controlling method of a dishwasher according to the present invention.

[0085]Referring to FIG. 6, dishes are stored within the dishwasher, after which the dishwasher is activated. Prior to this, water already in the unit undergoes an initial draining in step S21. After the initial draining has been performed, wash liquid is supplied and sprayed towards the dishes through the lower and upper spray arms 14 and 15 and the top spray nozzle 24.

[0086]During the spraying of wash liquid, larger food particles are washed in step S22. This wash cycle, which is not supplied with detergent, washes food residue using only wash liquid, and can therefore be called a pre-wash cycle.

[0087]After the pre-washing in step S22 is completed, steam is supplied into the tub18 in step S33. The supplying of steam in step S23 is sustained for a predetermined duration, which may extend for a period suitable to completely soak the deposits hardened on the dishes. The steam is...

Abstract

A dishwasher is provided. The dishwasher includes a tub, a steam generator, and a connecting passage. The tub stores dishes. The steam generator generates steam to be supplied into the tub. The connecting passage connects a discharging end of the steam generator to an inside of the tub.

Description

TECHNICAL FIELD[0001]The present invention relates to a dishwasher.BACKGROUND ART[0002]A dishwasher is a home appliance that sprays high-pressure wash liquid within a tub to wash and remove food residue and other impurities left on surfaces of dishes. A filter filters the food residue from the wash liquid to recycle the latter, and detergent is dissolved into the wash liquid to facilitate the removal of food residue.[0003]In order to improve the above dishwashing process, the following dishwasher functions have been developed.[0004]First, by heating wash liquid to aid in dissolving the detergent, overall dishwashing effectiveness can be improved. Also, by heating wash liquid, the wash liquid can more easily remove glutinous rice and other hardened food residue.[0005]Furthermore, by dividing the wash cycle of a dishwasher into a pre-wash cycle and a main wash cycle, the pre-wash cycle soaks hardened food residue, so that it can be more easily removed in the main wash cycle.[0006]Anot...
