<p>PURPOSE:To enhance user's convenience by displaying the time required until the water temp. at the present point of time reaches set water temp. when desired water temp. is set. CONSTITUTION:When water temp. is set by an inlet apparatus 6, the water temp. at this point of time is detected by the first, second and third temp. sensor circuits 10, 11, 12 and, at the same time, the circumferential temp. is detected by a circumferential temp. sensor 13. The time required until the water temp. at the present point of time changes by predetermined quantity is corrected on the basis of the circumferential temp. by a control apparatus 8 and the time required until the water temp. at the present point of time reaches set temp. is operated. This required temp. is displayed on a display device 16. By this method, when temp. is set, the time required until the water temp. at the present point of time reaches the set temp. is known at a glance and a cold and hot water machine good in user's convenience can be obtained.</p> |
