Abstract: A refrigerator has a flow path structure formed by a heat-exchanger. The refrigerator includes storage compartments, and a cool air supplying unit provided at a rear of the storage compartments to supply cool air at the storage compartments, and the cool air supplying unit includes a heat-exchanger to divide a flow path at which cool air is provided to flow along the cool air supplying unit.

Abstract: A washing machine and a method of controlling the washing machine are provided. In the washing machine and the method of controlling the washing machine, a liquid detergent is automatically supplied into a washing tub, thereby improving user convenience. In addition, in the washing machine and the method of controlling the washing machine, a liquid detergent is supplied into the washing tub by water circulated by a circulation unit. Thus, no liquid detergent remains in a liquid detergent supply path, and the liquid detergent supply path can be prevented from being blocked due to the solidification of a liquid detergent.

Abstract: A refrigerator includes a main body having a storage compartment, a door provided at the main body, a refrigerating portion which refrigerates the storage compartment using a compressor, a condenser, a depressurizer and an evaporator which are connected with a refrigerant pipe, and a heat transfer portion having a first flow passage portion which is disposed adjacent to the refrigerant pipe of the refrigerating portion and receives heat from the refrigerant pipe, and a second flow passage portion which is disposed at a front surface of the main body with which the door comes in contact and to which heat of the first flow passage portion is transferred. As a first cycle for refrigerating the storage compartment and a second cycle for providing heat to the front surface of the main body are provided separately preventing a decrease in refrigerating capability and an increase in power consumption.

Abstract: A washing machine is provided. The washing machine includes a support frame, which supports the main housing of the washing machine, and a liquid detergent container, which is disposed in the support frame and contains a liquid detergent therein. Therefore, the washing machine can improve the efficiency of the use of a liquid detergent.

Abstract: Disclosed is a washing machine, which prevents solidification of liquid detergent by rapidly recovering the liquid detergent left in a liquid detergent supply passage and a liquid detergent supply pump by forming a negative pressure differential by use of the liquid detergent supply pump for a set period of time after the supply of liquid detergent is finished.

Abstract: Disclosed is a washing machine, which can automatically supply a liquid detergent into a washing tub and automatically clean inner flow passages through which the liquid detergent has flown with a cleaning solution. A liquid detergent supply mechanism supplies at least one kind of liquid detergent to the washing tub, and the inner flow passages of the liquid detergent supply mechanism through which the liquid detergent has flown are cleaned with the cleaning solution supplied from outside.

Abstract: An ice maker and method for making ice are disclosed. The ice maker includes a compartment, an ice-making tray disposed in the compartment to receive and make ice, and a fan installed on the ice-making tray to make ambient air pass along the surface of the ice-making tray. The method includes selectively supplying chilled air to a compartment according to conditions of the compartment, continuously blowing chilled air in the compartment to an ice-making tray disposed in the compartment regardless of the conditions of the compartment, and distributing blown air on a surface of the ice-making tray uniformly.
