HOT WATER TANK FOR BEVERAGE SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a hot water tank for a beverage supply device capable of securing hot water of a prescribed temperature suitable for preparing beverage while reducing power consumption, and stably supplying the beverage.

SOLUTION: An upper heat insulating layer 75a of low heat conductivity is attached to an upper high-temperature hot water layer area storing hot water of high temperature, and a lower heat insulating layer 75b of heat conductivity higher than that of the heat insulating material attached to the high-temperature hot water layer area, is attached to an intermediate-temperature hot water layer area and a low-temperature hot water layer area stored at a lower part. A partitioning plate 72 of low heat conductivity is disposed in the hot water tank 70 approximately agreed with a joining portion of the upper heat insulating layer 75a and the lower heat insulating layer 75b.
