A refrigerator is described that includes a slim refrigerator door. The refrigerator includes a storage compartment, a refrigerator door to open and close the storage compartment, and an ice maker to generate ice cubes. The refrigerator further includes an ice bin-at the refrigerator door to receive the ice cubes generated in the ice maker and having a discharge opening-for discharging the ice cubes. The refrigerator further includes a motor-at the refrigerator-and at least one blade-within the ice bin and connected to the-motor. The at least one ice cube directly drops onto the at least one blade. The at least one blade moves the at least one ice cube to the discharge and discharges the at least one ice cube from the ice bin by an operation of the motor.

A multiple laundry treating machine, in which an auxiliary laundry treating device is coupled to a general laundry treating device, is disclosed. The multiple laundry treating machine includes a main laundry treating device for washing or drying laundry contained in an interior of the main laundry treating device, an auxiliary laundry treating device arranged at one side of the main laundry treating device, the auxiliary laundry treating device having a volume and a height respectively smaller than a volume and a height of the main laundry treating device, and having a laundry container formed in an interior of the auxiliary laundry treating device, and a connecting unit for connecting the main and auxiliary laundry treating devices, to enable communication or control operations between the main and auxiliary laundry treating devices. In accordance with the multiple laundry treating machine, it is possible to achieve a convenience in use and to save energy because a small amount of clothes or shoes can be dried by the auxiliary laundry treating device, without driving a laundry treating device having a relatively-large capacity.

The multiple laundry machine includes a laundry machine for washing or drying laundry contained in an interior of the laundry machine, an auxiliary drying device arranged at one side of the laundry machine, the auxiliary drying device having a laundry container formed in an interior of the auxiliary drying device, and a driver provided at the auxiliary drying device, to drive the auxiliary drying device.

Multiple laundry machine

A control method and system for a belt-driven clothes dryer are disclosed. The control system includes a drum containing a load of wet clothes to be dried, a heater heating air flowing into the drum, a motor coupled to the drum by a power transmission system for rotating the drum, and a power supply supplying power to the motor and the heater during a dry operation of the dryer. The control system further includes a moisture sensor outputting a sensor signal during the dry operation, or a photo coupler outputting voltage pulses when the motor is in operation during the dry operation. Then, a microprocessor included in the control system detects a breakage of the power transmission system upon analyzing the sensor signal of the moisture sensor or the voltage pulses generated by the photo coupler. If the microprocessor detects such breakage, it interrupts the dry operation of the clothes dryer.

Control method and system for clothes dryer

A laundry drier and control method thereof are provided, by which a new reference voltage is set to perform a next drying procedure if, upon a determination of a completion of a current drying procedure, there is a difference between a voltage representing a sensed level of water content (moisture) present in laundry and a sensed-moisture value at the end of the drying procedure, thereby compensating for the presence of contamination on and around the electrodes of a moisture sensor. The laundry drier includes a heater for performing a drying procedure; a moisture sensor for sensing a level of moisture in laundry during the drying procedure and outputting a voltage signal; a memory for storing a reference voltage value and a voltage value according to the sensed moisture level; and a microcomputer for controlling the heater based on the voltage signal output of the moisture sensor. The control method includes steps of driving a heater for a first predetermined time of a drying procedure; sensing a level of moisture in laundry after the first predetermined time has elapsed; storing in a memory a reference voltage value and a first value corresponding to the sensed moisture level; comparing the stored values, to determine a completion of the drying procedure; obtaining a second value corresponding to the sensed moisture level by driving the heater for a second predetermined time after the completion of the drying procedure; and compensating for an error in the sensed moisture level by resetting the reference voltage value according to a comparison of the first and second values.

Laundry dryer and control method thereof

A laundry drier determines an amount of laundry placed in the drier's drum and controls a dry pattern based on the amount of laundry. The laundry drier includes a rotatable drum having an interior for holding laundry; a moisture sensor, installed with respect to the interior of the rotatable drum, for measuring the water content of the laundry in the rotatable drum and outputting a value indicative of the water content; a voltage converter for converting the water content value output from the moisture sensor to a voltage and outputting a voltage signal; a pulse detector for outputting a pulse count generated from a contact count of the laundry coming into contact with the moisture sensor and outputting a pulsed signal indicative of the contact count; and a microcomputer for controlling the dry pattern based on the respective outputs of the voltage converter and the pulse detector.

Laundry dryer

A laundry drier has a heater control circuit for controlling the drive of a heater using one of a plurality of high voltages, using a switching circuit realized by a form C contact relay provided between a current-buffered microcomputer output and plurality of heater drivers, so that heater drive capability is ensured even if the current buffer output fails and so that dangerous short-circuit conditions are avoided even if the microcomputer experiences a logical malfunction. The heater control circuit includes a heater for being driven by a plurality of high voltages via a plurality of heater drivers; a microcomputer for outputting a control signal according to a user input, the control signal determining the high voltage drive of the heater; and a heater control interface for generating a plurality of heater control signals corresponding to the plurality of high voltages, based on the control signal of the microcomputer, the plurality of heater control signals selectively enabling only one heater driver.
