The present invention relates to an ice maker, and more particularly, to an ice maker used alone or in a refrigerator, a hot/cold water dispenser, a water purifier, and the like. The ice maker according to the present invention comprises: an ice making unit for making ice cubes using water; an ice crushing unit for crushing the ice cubes into crushed ice; a transfer unit for transferring the ice cubes or the crushed ice so as to extract the ice cubes or the crushed ice to the outside; and an extraction unit which has a conical shape with a diameter gradually decreasing from the top to the bottom thereof, which has a guide protrusion that forms a spiral shape in the vertical direction along the inner surface of the conical shape, and which rotates and drops the ice cubes or the crushed ice transferred by the transfer unit along the guide protrusion. The ice maker of the present invention may reduce the speed of the ice cubes or the crushed ice being discharging by exhausting the kinetic energy of the ice cubes or the crushed ice being dropped at a high speed.

The dryer according to the present invention comprises: a cylindrical drying tub having an opening on one side for receiving clothes; a hot air drying unit that circulates hot air in the drying tub in order to dry the clothes; and a magnetron unit provided toward the opening portion of the drying tub so as to allow microwaves to enter through the opening portion and scatter the entering microwaves onto the inner side surface in order to uniformly dry the clothes. The dryer according to the present invention is capable of preventing clothes from being damaged by high temperature and is capable of shortening the time taken to dry clothes by more rapidly and effectively removing the moisture contained in the clothes. Compared to conventional dryers, the present invention is capable of consuming 20% less power.

The present invention relates to a frosting and defrosting module and a refrigerator including the same, wherein the frosting and defrosting module is provided on the upstream side of an evaporator so as to have narrower fin intervals than the evaporator in which the temperature is lower than the temperature of air flowing through the evaporator to exchange heat with a refrigerant, in order to minimize frost formation on the evaporator which performs a refrigerant cycle in connection with a compressor, a condenser, and an expander. The present invention can minimize frost formation on an evaporator, and performs defrosting while carrying out normal functions of a refrigerant cycle, such as refrigerating, freezing and the like, thereby minimizing power consumed during defrosting and removing the inconvenience of stopping the operation of the refrigerant cycle or the like for the purpose of defrosting.
