Laundry Device

Abstract

Disclosed is laundry device having a steam generator (200), which prevents water from being excessively supplied to a case and steam generated from the case from adversely flowing toward a water supply valve (104), and removes overpressure due to steam generated in the case. A water oversupply prevention unit (220) for preventing the water from being excessively supplied to the case is a hollow floater, which moves vertically according to the amount of the water supplied to the case to open and close a water supply hole (211a). A backflow prevention unit (230) for preventing steam generated from the case from adversely flowing toward the water supply hole (211a) is a check valve, which allows the water to be supplied only to the inside of the case, prevents the steam generated from the case from flowing toward the water supply valve (104), and in installed between a water supply hole (211a) and the water supply valve (104). An air exhauster (400) for removing overpressure due to steam generated in the case is a relief valve (420), which is opened to remove overpressure due to steam generated in the case and is installed in a sub-pipe (410) branched from a steam supply pipe (106). Thereby, the steam generator is effectively operated, thus lengthening the lifespan of the laundry device and improving the reliability of

Description

TECHNICAL FIELD[0001]The present invention relates to a laundry device, and more particularly, to a laundry device having a steam generator, which prevents washing water, supplied to the inside of the steam generator, and / or steam, generated from the steam generator, from adversely flowing toward a water supply valve, and removes overpressure generated in the steam generator.BACKGROUND ART[0002]Generally, a laundry device is a general term used for apparatuses for washing clothing and bedding.[0003]The laundry device include a washing machine having only a washing function, a washing machine having washing and drying functions, and a drying machine having only a drying function.[0004]The washing machines are divided into pulsator washing machines, in which laundry is washed using a water current generated by rotating a plate-shaped pulsator, and drum washing machines, in which laundry is washed using a fall of washing water supplied to a horizontally-laid drum and the laundry and fr...

AI Technical Summary

Benefits of technology

[0032]The steam generator for the laundry device of the present invention has several effects, as follows.

[0033]First, a water oversupply prevention unit installed in the steam generator prevents water from being excessively supplied to the steam generator, even when a water level sensor malfunctions.

[0034]Thus, the water in the steam generator is not introduced into a drum, and a controller effectively controls the operation of the laundry device.

[0035]Although foul water or washing water in the drum adversely flows toward the steam generator due to back pressure generated from the drum, the water oversupply prevention unit in the steam generator closes a water supply hole, thereby preventing the foul water or the washing water from flowing to a water supply pipe through the water supply hole.

[0036]Thus, since the foul water or washing water does not flow toward the water supply valve connected to the water supply hole, it is possible to prevent the pollution of water supply facilities.

[0037]Second, a backflow prevention unit installed in the steam generator prevents the steam in the steam generator from leaking toward the water supply valve, even when back pressure is generated from the drum.

Problems solved by technology

In the soaking operation, a large amount of the washing water is consumed and a separate structure for sterilizing the laundry is not provided in the drum washing machine.

However, the drum washing machine requires excessively large amounts of the washing water and electric power to perform the boiling operation, thus not being preferably used.

Thereby, a controller of the drum washing machine 10 makes an error regarding the water supply, thus causing the drum washing machine 10 not to effectively perform a washing operation.
