| 20080250824 | Washing machine - A washing machine includes: a steam generator for generating steam; a circulation pump for pumping circulation water discharged from a tub and re-supplying it into a drum; a spray nozzle for spraying steam generated from the steam generator and the circulation water pumped from the circulation pump into the drum; and a back-current preventing branch unit connected to the steam generator by a steam supply line, connected to the circulation pump by a circulation line, and connected to the spray nozzle. With this structure, circulation water circulated by the circulation unit and steam generated from the steam generator are sprayed to the laundry through one spray nozzle, so that a system can be simplified and a fabrication cost can be reduced. | 10-16-2008 |
| 20080307833 | DRUM-TYPE WASHING MACHINE AND BEARING HOUSING STRUCTURE THEREOF - A drum type washing machine including a tub installed in a cabinet is disclosed. The drum type washing machine includes a drum performing washing, a motor rotating the drum, bearing housings having bearings to support a rotation shaft, a suspension connected to the bearing housings and the cabinet to mitigate vibration generated during rotation of the drum, a bracket installed to the bearing housings to form the rear side of the tub, and a gasket installed between the bracket and the tub to seal the tub and to prevent vibration from being transmitted from the bracket to the tub. Volumes of the tub and the drum can be easily increased without increasing the volume of the cabinet. Even when the volume of the washing machine is changed, only one of the tub and the bearing housings, which is not applicable to the drum type washing machine having the changed washing capacity, is selectively replaced. Thus parts can commonly used in various drum type washing machine having different volume. | 12-18-2008 |
| 20090120470 | WATER RECIRCULATOR IN DISHWASHER - A water recirculator in a dishwasher supplies water to spray arms for washing dishes and also purifies contaminated water after washing the dishes. The water recirculator includes a sump for holding water, a water supply pump connected to the sump, a guide passage for guiding a portion of the water pumped by the water supply pump to a spray arm in a washing chamber, a pre-filtering unit for purifying a rest of the water pumped by the water pumped by the water supply pump by means of precipitating contaminants included in the water therein, and a main filtering unit for purifying the rest of the water passed through the pre-filtering unit. | 05-14-2009 |

| 20090323913 | HOME APPLIANCE AND HOME APPLIANCE SYSTEM - A home appliance and a home appliance system are provided which control a sound output from an output device upon receipt of an external command signal of ON or OFF. Further, the home appliance and home appliance system control a sequence of output of an acoustic signal output from a conversion device. Accordingly, it may be possible to notify a user of the outputting of the acoustic signal by controlling the sequence of output of the acoustic signal, thereby increasing user convenience. | 12-31-2009 |
| 20090323914 | HOME APPLIANCE AND HOME APPLIANCE SYSTEM - A home appliance and a home appliance system are disclosed. Product information and status information of the home appliance are converted into at least one transmission acoustic signal, and a sound corresponding to the at least one transmission acoustic signal is output to the outside. The product information and status information are formed as a digital signal and stored in a storage device. The digital signal is encoded through a conversion device, and converted into at least one transmission acoustic signal. The at least one transmission acoustic signal is formed as an analog signal. Meanwhile, the at least one transmission acoustic signal can be dividedly formed. | 12-31-2009 |
| 20100023938 | HOME APPLIANCE AND HOME APPLIANCE SYSTEM - A home appliance and a home appliance system are provided. The home appliance receives input of a sound including update information, and updates a product operating program. The home appliance system receives a sound including product information from the home appliance, judges whether to update the product operating program of the home appliance, and transmits update information. | 01-28-2010 |
| 20100026507 | HOME APPLIANCE AND HOME APPLIANCE SYSTEM - A home appliance and a home appliance system are provided. The home appliance may convert product information into an acoustic signal and externally output the same as a sound. The home appliance system may receive the sound, convert the same into the acoustic signal, and then inversely convert the acoustic signal into the product information and read the same. Accordingly, the home appliance may externally output the acoustic signal as the sound so that the user may be easily notified of transmission. Also, the home appliance system may easily transmit the sound to a management device to read the product information because the sound may be transmitted via a communications network. | 02-04-2010 |
| 20100027770 | HOME APPLIANCE SYSTEM AND OPERATION METHOD THEREOF - A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound. | 02-04-2010 |
| 20100066554 | HOME APPLIANCE SYSTEM - A home appliance system includes a home appliance outputting product information as a sound and a mobile terminal confirming the product information based on the sound. The mobile terminal can receive the sound, convert the sound into the product information and output the product information to an external user and a repairman. | 03-18-2010 |
