Description

TECHNICAL FIELD

BACKGROUND

An ice maker is a refrigerating apparatus in which water is cooled by a refrigerating system through an evaporator to generate ice, and ice cubes prepared by the ice maker are stored in the ice maker to be used by a user. The ice makers are widely used in cold drink shops, cafes and ordinary families. The related art ice maker has a structure generally comprising a housing, as well as a compressor, a condenser, an evaporator, a water tank, an ice making machine and a water pump configured to introduce water in the water tank into the ice making machine and the like which are connected in the housing. After the evaporator completes ice making and deicing, ice is collected by an ice receiving basket in the water tank. During the whole ice making process or after ice making is completed, water in the ice making machine or ice-melting water flows back to the water tank for collection, and the water in the water tank is then pumped by the water pump to the ice making machine to make ice.
