20110107779 | Frost detecting apparatus, and cooling system and refrigerator having the same - A frost detecting apparatus including a first electrode to generate an electric field in a frost detection region, a second electrode to prevent the electric field from leaking into a frost non-detection region, an insulator arranged between the first electrode and the second electrode, to insulate the first electrode, and a shield arranged around an exposed portion of the insulator, to prevent the electric field from leaking into the frost non-detection region through the exposed portion of the insulator. As the same potential is established at the first and second electrodes, it is possible to prevent electric field from leaking into a frost non-detection region through side surfaces of the first electrode. Accordingly, the electric field is varied only by frost formed in a frost detection region, so that it is possible to more accurately detect formation of frost and the amount of the formed frost. | 05-12-2011 |
20110197605 | Heat exchanger and refrigerant cycle device using the same - A heat exchanger usable as an evaporator in a refrigerant cycle device includes a heat exchanging portion configured to perform heat exchange between refrigerant and air so as to evaporate the refrigerant. A thermal deformation member is provided in en entire range on a surface of the heat exchanging portion, to be deformed bordering on a predetermined temperature when the surface of the heat exchanging portion is frosted to produce ice. The thermal deformation member is deformed by a temperature change between a first temperature lower than the predetermined temperature and a second temperature higher than the predetermined temperature, to cause distortion between the surface of the heat exchanging portion and the ice when the ice is attached to the surface of the heat exchanging portion. Thus, the ice attached to the surface of the heat exchanging portion can be effectively removed while heat energy for removing the ice can be reduced. | 08-18-2011 |
