FIELD OF THE INVENTION

The present invention relates to an ice mold releasing system to be installed preferably in a refrigerator, and particularly, in a refrigerator with said system.

BACKGROUND

The following are known in the state of the art

- Ice mold releasing systems, where in order to release the ice from the mold, it is necessary to twist the container where the ice itself is formed, wherein the problem which said twisting systems suffer from is the reliability of the material subjected to the twisting. Generally said containers tend to suffer fractures which eventually lead to spilling, so that replacing these systems is constant;
- Systems in which the container in which the ice is formed, present upper and lower surfaces, housings for the forming of ice, so that the releasing of ice from the container involves twisting the container 180° in order to fill out the exposed surface, causing, given the temperature difference, that the opposite side to the container is emptied out, where the problems facing said twistable systems are the formation of ice masses in the container given the formation of droplets in light of the temperature differences between the filling water and the ice on the opposite side of the container.

In order to address said problems, present invention has been developed.
