摘要： A method for controlling a refrigerator having a direction control valve drives a refrigerating fan for a predetermined time when a refrigerant passage is converted to make a refrigerant from a condenser firstly pass a refrigerating evaporator, and enhances a cooling efficiency by applying a residual cool air of the refrigerating evaporator to a refrigerating compartment, after the refrigerating compartment reaches a steady state in a refrigerator having a refrigerating evaporator embodied as an intercooler evaporator. The method includes the steps of: (a) determining whether a refrigerating compartment temperature sensed by a refrigerating compartment temperature sensor reaches a refrigerating compartment set temperature to determine a steady state of a refrigerating compartment; (b) if it is determined that the steady state of the refrigerating compartment in the step (a), switching a direction control valve, and allowing a refrigerant to firstly pass a refrigerating evaporator; (c) if the direction control valve is switched in the step (b), driving a refrigerating fan for a predetermined time simultaneously driving a freezing fan; and (d) if the refrigerating fan is driven for the predetermined time in the step (c), stopping the refrigerating fan.

摘要： An automatic ice maker includes an ice-making tray rotatable between an upright ice-making position, and an inverted ice-discharging position. A container disposed beneath the tray receives the discharged ice. A cam wheel rotates with the tray and includes first and second cams that actuate first and second switches, respectively. A controller connected to the switches determines the position of the tray on the basis of the states of the switches. A lever detects whether the container is full of ice. When the container is full, the lever actuates the second switch in order to prevent further ice-making operations, regardless of the orientation of the first and second cams.

摘要： An automatic ice maker adapted for use in a refrigerator includes an ice-making tray rotatable between an upright ice-making position and an inverted ice-discharging position by a motor. A container is disposed beneath the tray for receiving ice when the tray is in the inverted position. First and second switches are each moved between first and second states in response to rotation of the tray. The second switch can be moved to its second state in response to the container being full of ice. Whenever the refrigerator is started-up, e.g., after a power outage, a controller determines whether both of the switches are in their first states. If so, an ice making operation is performed. If not, the motor is actuated in a manner tending to rotate the tray to its upright position. When the tray reaches its upright position, a stop is contacted, whereupon a load is generated at the motor, causing the controller to stop the motor.

摘要： When a user manually sets a desired (target) temperature for a refrigerator chamber, a control mechanism automatically determines a range of target temperatures having upper and lower limits. Actuation and deactuation of the refrigeration cycle is controlled in response to a comparison of the chamber temperature with the upper and lower limits, respectively. When an outside temperature surrounding the refrigerator rises above a reference temperature, those upper and lower limits are automatically lowered. Also, the control mechanism compares the manually set temperature with a range of temperatures which the refrigerator is capable of achieving and automatically selects an achievable temperature if the manually selected temperature lies outside the achievable range. Moreover, a quick-freeze operation of the control mechanism enables a freezing chamber to be brought rapidly to a cold temperature. Furthermore, the temperature balance between freezing and refrigerating chambers of the refrigerator is controlled by an actuator-driven damper. Once a sensor signals that the damper has arrived at an open or closed position, the damper is continued to be driven for a predetermined time period to compensate for the possibility that the damper-arrival signal was produced prematurely.
