即湯機能付き給湯器
Document Type and Number:
Japanese Patent JP3605816
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To decide whether a hot water supply plug is used or not with high accuracy through a simple arrangement by disposing a supply water temperature sensor on the downstream side of the joint between a supply water path and a hot water return path and making the decision based on the temperature detected by the supply water temperature sensor. SOLUTION: This hot water supply apparatus with quick supply function heats the supply water from a supply water path 2 by a heat exchanger 3 and feeds hot water to a hot water delivery path 4. On the other hand, the hot water supply apparatus feeds the water regulated by a proportional valve 11 through a bypath 10 to the hot water delivery path 4 where the water is mixed with the hot water. A hot water return path 6 is also provided in order to supply hot water from the hot water delivery path 4 to a hot water supply plug 5 and to return hot water from the hot water delivery path 4 to the supply water path 2 and the hot water return path 6 is provided wish a circulation pump 7. Furthermore, a supply water temperature sensor 12 is disposed on the downstream side of the joint between the supply water path 2 and the return path 6 and opening of the hot water supply plug 5 is detected by detecting temporary temperature drop of the supply water temperature sensor 2.
