COLD KEEPING METHOD BY ELECTRIC HOT WATER STORAGE CONTAINER, AND ELECTRIC HOT WATER STORAGE CONTAINER ADOPTING THE METHOD

摘要

PROBLEM TO BE SOLVED: To perform cold keeping without generating the problem of moisture condensation on a circuit board. SOLUTION: This cold keeping method cold keeps a housed article at less than an environmental temperature by an electric hot water storage container in the container having a vacuum double structure which accompanies a heating control by a heater in the container body and the circuit board, and feeds hot water for use while storing the hot water. The purpose is achieved by keeping the circuit board by heating at a temperature or higher by which moisture condensation can be prevented from occurring. COPYRIGHT: (C)2005,JPO&NCIPI
