HOT WATER PREPARATION METHOD Russian patent published in 2020 - IPC E03B1/04 F24H1/00 

FIELD: satisfaction of vital human requirements.

SUBSTANCE: invention relates to preparation of hot water for domestic and household needs. Method consists in preparation of hot water by means of storage container (5) containing inlet branch pipe of cold water (6), inlet connection pipe of hot water (7), overflow branch pipe (13), outlet branch pipe, water temperature sensor (10) in a storage container, a water temperature sensor (11) in the inlet branch pipe of hot water, control unit (12). Accumulating reservoir (5) is supplemented with float switch K1 (14) located below level of overflow, and float switch K2 (15) located above level of overflow. Then, current water temperature T is measured and compared with temperature settings T1, T2, T3, T4, where T1 is less than T2, T2 is less than T3, T3 is less than T4. Further, if T of water is less than T1, cold water supply is switched off if water T is greater than T2, then cold water supply is switched on if water T is less than T3, then hot water is switched on if water T is greater than T4, then hot water supply is switched off, and if, after operation of float switch K1, T of water is in range from T1 to T4, then water set is stopped, otherwise water set is continued until required temperature is obtained, or before actuation of float switch K2. If during the hot water supply time t1 the temperature in the inlet branch pipe of the hot water is less than the setting value T5, the hot water supply is terminated and resumed after the time t2.

EFFECT: water saving, short water preparation time for consumption, maintenance of required water temperature during the consumption cycle, comfortable use of hot water, absence of user dependence on availability of electric energy and water in supply pipelines of cold and hot water during consumption.
