A refrigerator has a vacuum space formed between an outer case and an inner case of a body thereof for enhancing a heat insulating function. The refrigerator includes a body having a storage space for storing a predetermined storage object, wherein the body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, and a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case.

Refrigerator comprising vacuum space

The refrigerator includes a body having a storage space for storing a predetermined storage object, wherein the body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an inside surface of the inner case to house the inner case, a vacuum space provided between the inner case and the outer case enclosed to maintain a vacuum state for heat insulating between the inner case and the outer case, and a sealing unit for sealing a front of the vacuum space formed between a front of the inner case and a front of the outer case and reducing a heat transfer rate between the inner case and the outer case.

A method for controlling a refrigerator includes operating, for a set duration, a heating element of a sensor which responds to changes in air flow; sensing the temperature of the heating element in on or off state; and sensing residual frost on an evaporator on the basis of the difference in value of the temperature between a first sensed temperature, which is the lowest value, and a second sensed temperature, which is the highest value, from among the sensed temperatures of the heating element.

Refrigerator and method for controlling the same

This invention relates to refrigerators, and more particularly to a refrigerator in which a vacuum space is formed between an outer case and an inner case of a body thereof for enhancing a heat insulating function. The refrigerator includes a body having a storage space for storing a predetermined storage object, wherein the body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, and a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case.

A refrigerator includes a body having a storage space. The body includes an inner case having the storage space, an outer case having an inside surface spaced a predetermined gap from an outside surface of the inner case to house the inner case, a vacuum space provided between the inner case and the outer case sealed to maintain a vacuum state for heat insulating between the inner case and the outer case, a supporting portion provided to contact with the outside surface of the inner case and the inside surface of the outer case to maintain a spaced state of the vacuum space, and a dewing preventive unit adjacent to the supporting portion for preventing dewing from taking place at the outer case by suppressing surface temperature drop of the outer case caused by cold conducted from the inner case to the outer case through the supporting portion.

Refrigerator with vacuum space

A refrigerator of the present invention comprises: an inner case forming a storage compartment; a cold air duct guiding the flow of air within the storage compartment and forming a heat exchange space with the inner case; an evaporator disposed in the heat exchange space between the inner case and the cold air duct; a bypass passage disposed in the cold air duct so as to allow the flow of air to bypass the evaporator; a sensor disposed in the bypass flow channel and comprising a sensor housing, a sensor PCB received in the sensor housing, a heating element installed on the sensor PCB so as to generate heat when an electric current is applied thereto, a temperature element for sensing the temperature of the heating element, and a molding material with which the sensor housing is filled; a drfrosting means for removing frost formed on the surface of the evaporator; and a control unit for controlling the defrosting means on the basis of the value output from the sensor.

Refrigerator

An evaporating device includes: an evaporator, a defrost heater, and an evaporation pan, wherein the evaporation pan is made of aluminum and the inner side of the evaporation pan is coated with a surface treatment to improve the melting of ice in the evaporation pan.
