Abstract
The present invention relates to a system and method for making ice, and more particularly, to an ice maker provided in a refrigerator and an ice making method using the same. A system for making ice according to the present invention comprises a tray for containing a water to be used for making ice; and an ice-making pipe disposed so that at least a portion thereof is submerged in the water contained in the tray, wherein a refrigerant of relatively low temperature flows to the ice-making pipe during an ice-making process, while a refrigerant of relatively high temperature flows to the ice-making pipe during an ice-releasing process.
Claims14
A system for making ice, comprising:
- a tray for containing a water to be used for making ice;
- and
- an ice-making pipe disposed so that at least a portion thereof is submerged in the water contained in the tray,
- wherein a refrigerant of relatively low temperature flows to the ice-making pipe during an ice-making process, while a refrigerant of relatively high temperature flows to the ice-making pipe during an ice-releasing process.
A system for making water, comprising:
- a compressor;
- a condenser for allowing a refrigerant having passed through the compressor to flow in the condenser;
- an expansion valve for expanding a refrigerant having passed through the condenser into a refrigerant of relatively low temperature and low pressure;
- an ice-making pipe extending from an outlet of the expansion valve, the ice-making pipe being curved or bent several times to form a plurality of protrusions;
- and
- a tray for containing water to be used for making ice, the tray being rotated during an ice-making process,
- wherein the protrusions are at least partially submerged in the water to be used for making ice.
A method for making ice, comprising the steps of:
- storing water to be used for making ice in a tray;
- causing a refrigerant of relatively low temperature to flow through an ice-making pipe provided in an inner space of the tray;
- forming ice on a surface of the ice-making pipe;
- and
- releasing the ice formed on the surface of the ice-making pipe.
