Claims

[Claims for Utility Model Registration] A valve body that can stop the water flow by coming into contact with the opening that communicates the ice compartment with the vacant room, and one or more locations on the part of the valve body other than the abutment area. A small hole is formed through the hole in the direction of communicating the ice chamber and the empty chamber, and a shape memory part is attached to the valve body, with a part of the hole abutting the small hole and the other part being attached to the valve body. One piece. When the temperature drops to near the freezing point, the shape is curved in a certain direction to unshield the small hole, and when the temperature rises and the freezing point is reached, it returns to the 9-0 shape again. Anti-freeze valve having shielding properties. one
