Abstract

A flow-type ice maker including substrate, an ice-making part configured by a refrigerant pipe connected to a refrigerator and through which a refrigerant circulates in an airtight manner, an ice-making rack supporting the refrigerant pipe and including an ice mold formed along an outer periphery of the refrigerant pipe, an ice-making water flow part joined to an upper part of the ice-making rack and allowing ice-making water to flow into the ice-making rack, and an ice-separating member to rotating around a direction parallel to the axis center of the refrigerant pipe to separate ice formed in the ice mold, and an ice-making water feed pipe feeding ice-making water to the ice-making water flow part. The refrigerant pipe has a curved part; and an outer periphery of a pipe made of any one of copper and aluminum is covered with stainless steel.

Claims

1. A flow-type ice maker comprising:

an ice-making part configured by

a refrigerant pipe connected to a refrigerator and through which a refrigerant circulates in an airtight manner,

an ice-making rack supporting the refrigerant pipe and including an ice mold formed along an outer periphery of the refrigerant pipe,

an ice-making water flow part joined to an upper part of the ice-making rack and allowing ice-making water to flow into the ice-making rack, and

an ice-separating member to rotating around a direction parallel to the axis center of the refrigerant pipe to separate ice formed in the ice mold; and

an ice-making water feed pipe feeding ice-making water to the ice-making water flow part, wherein;

the refrigerant pipe has a curved part; and

an outer periphery of a pipe made of any one of copper and aluminum is covered with stainless steel.

2. The flow-type ice maker according to claim 1, wherein

the refrigerant pipe of the curved part has an radius of curvature that is twice to ten times the pipe outer diameter of the refrigerant pipe.

3. The flow-type ice maker according to claim 1, wherein

the refrigerant pipe has a pipe outer diameter of 8 to 20 mm.

4. The flow-type ice maker according to claim 1, wherein

in the refrigerant pipe, a ratio of a thickness of the pipe made of any one of copper and aluminum to a thickness of a pipe made of stainless steel is 1:

0.2 to 1;

2.

5. The flow-type ice maker according to claim 1, wherein

the refrigerant pipe is a refrigerant pipe having a groove formed on a pipe inner wall.

6. The flow-type ice maker according to claim 5, wherein

the groove formed in the refrigerant pipe is a plurality of helical grooves.
