<P>PROBLEM TO BE SOLVED: To suppress manufacturing costs by reducing the number of arrangements of a refrigerant detection means. <P>SOLUTION: An ice storage chamber 11 and a machine chamber 12 communicates with each other spatially through a piping space 45 accommodating the third connection pipe 35C and the fourth connection pipe 35D of a freezing mechanism E. A refrigerant detection sensor S, which can detect the refrigerant leaking out of the freezing mechanism E, is arranged below a portion communicating with the piping space 45 in the machine chamber 12. Thus the refrigerant leaked out of the freezing mechanism E in the machine chamber 12 can be detected with the refrigerant detection sensor S, and the refrigerant leaked out of the freezing mechanism E in the ice storage chamber 11 flows into the machine chamber 12 through the piping space 45, which can be detected with the refrigerant detection sensor S to property detect the leak out of the refrigerant from the freezing mechanism E with one refrigerant detection sensor S. <P>COPYRIGHT: (C)2013,JPO&INPIT |
