Method for preventing formation of ice on a damper in a refrigerator, comprising the steps of (1) driving a compressor and a fan and opening baffles if a freezing room temperature is lower than a freezing room reference temperature and a chilling room temperature is lower than a chilling room reference temperature, (2) comparing the chilling room temperature to the chilling room reference temperature, to close the baffles if the chilling room temperature is lower than the chilling room reference temperature, (3) comparing the freezing room temperature to the freezing room reference temperature, to stop the compressor and the fan if the freezing room temperature is lower than the freezing room reference temperature, (4) comparing an outside temperature of the refrigerator to an outside reference temperature, to return back to the step (1) if the outside temperature of the refrigerator is higher than the outside reference temperature, and determining chilling room door of being opened if the outside temperature of the refrigerator is lower than the outside reference temperature, and (5) comparing a temperature difference before and after opening/closing of the chilling room door to a given reference temperature, to return back to the step (1) if the temperature difference is lower than the reference temperature, and to open the baffles of the damper and to drive the fan for a given time period if the temperature difference is higher than the reference temperature.

Method for preventing formation of ice on damper in refrigerator

A concentrated cool air supply device for refrigerators is disclosed. In the device, a branch duct is branched from the cool air passage to guide the cool air to the door. A door duct is formed on the door to receive the cool air from the branch duct. The door duct has a plurality of air outlet openings on a cover plate. The outlet openings of the door duct are selectively opened by a slide panel, thus concentrically discharging the cool air from the door duct into a desired portion of the compartment. In order to move the slide panel, the device also has a motor, a rotatable link and a connecting rod. The link is coupled to the motor, thus being selectively rotated by the motor, while the connecting rod is connected to the link and the slide panel at both ends.

A cool air supplying device for a fresh food compartment in refrigerators is disclosed. In the device, a cool air passage extends from an evaporator to the fresh food compartment. A connection duct is branched from the passage and extends to a front portion of the fresh food compartment. A plurality of door ducts are provided on the door of the fresh food compartment and individually have an air inlet opening at a position selectively aligned with an associated one of the air outlet openings of the connection duct. The door ducts also have a plurality of air outlet ports capable of discharging cool air from the door ducts into the fresh food compartment rearwardly. The amount of cool air for the air outlet openings of the connection duct is controlled by a cool air distribution unit. The air distribution unit has a motored regulator.

Cool air supplying device for fresh food compartment in refrigerators

An apparatus for and a method of supplying cold in a refrigerator, wherein respective temperatures at a plurality of different portions of the interior of the refrigerator are sensed so that cold air is selectively supplied to each refrigerator portion based on the sensed temperature associated with the refrigerator portion, thereby effectively maintaining the refrigerating and freezing compartments of the refrigerator at predetermined temperatures, respectively. The apparatus and method are also configured to concentratedly supply cold air to a portion of the refrigerating compartment of the refrigerator in which a new load is stored. When at least one of the sensed temperatures of the freezing compartment and different portions of the refrigerating compartment is higher than an associated set temperature, concentratedly supplying cold air to the compartment or compartment portion exhibiting the temperature higher than the set temperature. When the sensed temperatures of the freezing compartment and refrigerating compartment portions are higher than the associated set temperatures, respectively, cold air is uniformly supplied to both the compartments.

Method of supplying cold air in refrigerators

An apparatus for and a method of supplying cold air to a refrigeration compartment door passing through a distributing duct provided in the apparatus, are disclosed. A refrigerator with the apparatus includes at least one compartment for preserving foods at a cold temperature, a first duct for supplying cool air to one portion of the compartment, a second duct for supplying the cool air to the other portion of the compartment and a pair of blower fans mounted in order to introduce the cool air to the first and second ducts, respectively. Therefore, the interior of the refrigeration compartment is maintained at a desired low temperature, thus allowing foods in the refrigeration compartment to be always maintained at the desired low temperature.

Apparatus for supplying cold air in refrigerators

A refrigerator includes a fresh food compartment, a freezer compartment defined by inner walls and an outer case respectively, an insulation barrier separating the compartments, and doors for providing access to the compartments. A passageway is formed in the barrier for providing refrigerated air to the fresh food compartment. A connecting duct diverges from the passageway and extends forwardly towards the front portion of the fresh food compartment. A door duct communicating with the connecting duct when the door is closed is coupled to the door. As a result, the fresh food compartment and door-adjacent portions of the fresh food compartment are promptly and uniformly cooled.

Refrigerated air supply apparatus for refrigerator

A cold air circulation device and method for a refrigerator, the refrigerator including a refrigerating compartment, a first door for providing access to the refrigerating compartment, a freezing compartment, a second door for providing access to the freezing compartment, and a cold air supply unit for supplying a cold air to the refrigerating and freezing compartments. The air circulation device and method include a first door duct formed within the first door, the first door duct including at least one inlet formed at a lower portion of the first door for receiving a circulated air from the refrigerating compartment, and an outlet formed at an upper portion of the first door for outputting the air from the inlet to the cold air supply unit.

Cold air circulation device of refrigerator

A cool air supply system for refrigerators, capable of guiding cool air from the freezer compartment of a refrigerator to the refrigeration compartment door, wherein the cool air supply system includes a distributing duct, designed for guiding cool air circulated through a freezer compartment to a refrigeration compartment door&lt; and a door duct disposed in the door where it can be selectively connected to the distribution duct. The distribution duct has a return duct designed for introducing the cool air to an evaporator and a branch duct which diverges from the return duct. Thus, the cool air, introduced into the door duct from the distribution duct and branch duct is readily discharged from the door to the inside of the refrigeration compartment.
