Abstract

PURPOSE:To heat water at low cost and carry out additional heating quickly, by installing apparatuses for circulation, filtration, and heating to draw warm water from a bathtub and return the water again to the tub and equipping a heat pump to keep warmth and an electric heater to heat the warm water additionally. CONSTITUTION:Warm water in a bathtub 1 is drawn by the operation of a circulation pump 6 and led to a circulation route 2 to filer the hair and the scum. Then, the warm water passes the circulation pump 6, heated by heat- exchange in the condenser 8 part of a heat pump 7, and kept warm in order to prevent water in the bathtub 1 from cooling. Next, after the warm water heated additionally by the condenser 8 is filtered with a second filter part 9 to remove fine objects to be removed, it is led to the heater 10 for additional heating, sterilized in a sterilizing part 20, and returned to the bathtub 1. Thus, normally the heat-exchanger 8 of a heat pump 7 only works for keeping the warmth of circulating water but when necessary, additional heating is carried out quickly by the additional heating electric heater 10.
