Title:
BATHTUB WATER PURIFYING DEVICE WITH HEAT STORAGE TANK
Document Type and Number:
Japanese Patent JP3947298
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent heating of an empty heat storage tank by providing a pressure sensor for detecting pressure at a specified position of a circulation passage formed by means of a circulation passage forming means.
SOLUTION: Water of a bathtub 1 is measured the temperature thereof by a hot water temperature sensor 3 via an outgoing water pipe 2, sent to a filter tank 6 from a circulation pump 4, filtered therein, and returned from an incoming water pipe 10 to the bathtub 1 through a switching valve V1 and a switching valve V2. A pressure sensor 5 detects the pressure difference between an inlet and an outlet of the circulation pump 4. In the heat storage tank 7 is provided a regenerative heater 8, a switching valve V1 is switched to introduce bathtub water from a lower part of the heat storage tank 7, hot water from an upper part of the heat storage tank 7 is switched on the side of a mixing part 9 to mix bathtub water of normal temperature from the switching valve V1 and hot bathtub water from the heat storage tank 7 under this pressure, the mixed bathtub water is supplied to a pipe line in front of the switching valve V2 so as to supply heated batutub water to the heat storage tank 1 through the water inlet pipe 10.
