| 20110100047 | REFRIGERATOR WITH ICE MAKING ROOM - Disclosed herein is a refrigerator having an ice-making chamber, and the refrigerator may include a refrigerator body and an ice-making chamber, and the ice-making chamber may include an ice-making chamber body one side of which is opened, a connecting duct provided in a first sidewall of the ice-making chamber to be connected to the refrigerator body, an ice-making chamber door provided at a second sidewall of the ice-making chamber to open and close the ice-making chamber, and a protrusion portion formed to be protruded at the first sidewall. Accordingly, the thickness of the ice-making chamber door can be secured without changing a cool air channel of the ice-making chamber, thereby increasing a cooling chamber. | 05-05-2011 |
| 20120024000 | ICE MAKING MACHINE - Provided is a device for cooling a condenser of an ice making machine. Water and air are simultaneously supplied to the surface of the condenser, and heat of vaporization absorbed during evaporation of the water is used, thereby maximizing cooling performance on the condenser just with a small amount of water. In addition, power consumption for operating a blower fan, and a noise from the blower fan can be decreased. In addition, since cool water generated from ice stored in a storing compartment is sprinkled to the condenser, the condenser can be more effectively cooled. In addition, since meltwater is used, water consumption for cooling can be significantly reduced. | 02-02-2012 |

| 20110099598 | DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA IN DIGITAL BROADCASTING SYSTEM - A digital broadcasting system and a method for processing data in the same are disclosed. A method for controlling a digital television (DTV) located in one independent space among a plurality of independent spaces physically separated from one another is disclosed. The method includes receiving a broadcast signal from a management server, processing the received broadcast signal using a hospitality middleware platform embedded in the DTV, and outputting audio/video (A/V) data on the basis of the processed broadcast signal. The hospitality middleware platform may include a switching layer for switching a first layer for processing a broadcast signal based on a broadcast standard of a first region and a second layer for processing a broadcast signal based on a broadcast standard of a second region, a flexible Digital Rights Management (DRM) layer capable of being voluntarily modified, and a downloadable engine layer capable of voluntarily programming an interactive service application. | 04-28-2011 |
