Abstract

PURPOSE:To always supply the hot water having a safe and comfortable temperature by a method wherein, based on the skin temperature of a user obtained by a skin temperature detecting means, the temperature of hot water to be supplied is determined and the temperature of the hot water supplied is so controlled as to attain the temperature thus determined. CONSTITUTION:When a hot water supply end device 13 is opened, a water flow switch 14 detects the flow of a fluid in a supply pipe 9 and the signal is sent from the water flow switch 14 to a temperature control means 12 to start the temperature control. The skin temperature of a user near the hot water supply end device 13 is read out by a skin temperature detecting means 10 for detecting his skin temperature. Based on the skin temperature of the user so read, the hot water temperature considered as the most comfortable is computed and determined by a temperature setting means 11. The signal of the temperature thus determined is sent to the temperature control means 12. By the temperature control means 12, the mixing of the hot water from a hot water supply pipe 7 and the water from a water supply pipe 8 is so controlled as to attain the determined temperature and the hot water which has attained this temperature is sent to a supply pipe 9. Thus, there is obtained the hot water supplied from the supply pipe 9 and having a temperature commensurate with that considered as the most comfortable to the skin of the user.

It can supply hot water at a temperature that is comfortable and safe for use by the elderly and children, and also provides the convenience of forcibly changing the hot water temperature to the user's desired temperature depending on the usage pattern. .

The temperature control device according to claim 6 is provided with a setting changeover switch that can switch between a method of dispensing hot water at a temperature corresponding to the skin temperature and a method of forcibly dispensing hot water at an arbitrary temperature. It is possible to provide convenience in that the user can freely select between a system that allows the user to change the temperature of hot water to a desired temperature according to the form, and a system that uses hot water at a comfortable temperature that corresponds to the skin temperature. In other words, if an elderly person or a child who does not know how to adjust the hot water temperature is using the water heater alone, they can obtain safe and comfortable hot water by selecting the hot water temperature setting method that corresponds to their skin temperature. When a housewife uses a water heater to use hot water at various temperatures, she can provide hot water at the desired temperature by selecting a hot water temperature setting method that allows her to freely adjust the temperature.
