Abstract: An evaporator manufacturing method includes providing cooling fins each formed with a pair of coolant tube accommodation parts, and expanding a first coolant tube and a second coolant tube after inserting the first coolant tube and the second coolant tube into the coolant tube accommodation parts of the plurality of cooling fins; providing a first jig and a second jig at different levels to bend the expanded first coolant tube and the expanded second coolant tube; bending the first coolant tube around the first jig alternately to form several horizontal parts spaced apart from each other along a vertical direction, and at the same time bending the second coolant tube around the second jig alternately to form several second horizontal parts spaced apart from each other along the vertical direction so that the second horizontal parts are positioned to the rear of spaces between the respective first horizontal parts; and connecting the first coolant tube and the second coolant tube.

Abstract: A refrigerator with a multipurpose storage chamber and a control method. In the refrigerator, the flow of cool air to the multipurpose storage chamber is selectively controlled in accordance with a variety of operational modes. In order to accomplish such a cool air flow control, a refrigerating compartment fan and a damper are provided at positions above a refrigerating compartment evaporator. In addition, a flap, controlled at an open angle thereof, is provided at the inlet of an air guide path guiding the cool air to the multipurpose storage chamber. The multipurpose storage chamber of this refrigerator can thus effectively be used to store a variety of foods in accordance with storage characteristics of the foods. In addition, a thawing mode operation of the refrigerator is performed under the condition that it is not necessary to perform a refrigerating compartment cooling operation.

Abstract: A refrigerator includes a freezing chamber and a refrigerating chamber located beneath the freezing chamber and separated therefrom by a partition. An evaporator is disposed in the partition for cooling air received from the freezing and refrigerating chambers. A fan circulates that air to the evaporator and then back to the chambers. An air passage disposed in the partition communicates the refrigerating chamber with the evaporator. An air sterilizing and deodorizing mechanism is disposed at an upstream end of that passage for treating air leaving the refrigerating chamber and entering the passage.

Abstract: An evaporator of an ice machine operating on a typical ice-making cycle, comprising a heat-conducting metal plate member, an evaporator body formed by folding the metal plate member into a " "-shape after a refrigerant circuit including a capillary tube, refrigerant tube and evaporating tube etc., is oppositely mounted inside of the plate member, and means for fixing the evaporator body in a vertical position inside of the cabinet of an ice machine. The present invention improves productivity by resolving disadvantages such as the increase of the installation space and complex assembly. Moreover, easier and more accurate ice-separating may be attained according to the present invention.
