摘要： PURPOSE:To make it possible to fill hot water precisely to a set water level by a method wherein a filling flow rate per unit time in an initial stage of operation is used and when the flow rate is equal to or larger than a certain flow rate, sensing of inflection point is utilized, and when the flow rate is smaller than the certain flow rate, circulation judgement is repeated to decide a water level wherein make-up firing circulation is possible. CONSTITUTION:When a flow rate per unit time is equal to or larger than a certain value, two-side transfer is finished, and while one-side transfer, wherein filling hot-water into a bathtub is performed through a bathtub return pipe 21, bathtub feed pipe 22, and an inner-side pipe 11b of a bathtub circulation fitting 11, is being performed, sensed output of a bathtub water level sensor 52 is monitored by a controller 60 to sense a point of inflection. And a certain amount of water is filled into a bathtub 10 by two-side transfer so that the water level reaches a water level H which exceeds slightly a hole of the fitting 11. When a flow rate per unit time does not reach the certain value, the controller 60, after completion of the two-side transfer, changes over a three-way valve 51 to decide whether or not bathtub water circulates through a circulation circuit 20. As a result, hot water can be filled precisely to a set water level.

摘要： PURPOSE:To reduce noise at the time of circulation judgement by a method wherein when a flow rate per unit time is equal to or larger than a certain flow rate, a shorter circulation judging time is used to perform a circulation judgement and when it is smaller than the certain flow rate, a longer circulation judging time is used to perform the circulation judgement. CONSTITUTION:When a flow rate per unit time is below a first flow rate, a controller 60 judges whether or not the flow rate per unit time is equal to or larger than a second flow rate which is smaller than the first flow rate and when it is not less than the second flow rate, a first circulation judgement is performed and when it is below the second flow rate, a second circulation judgement is performed. The second flow rate is determined beforehand by an experiment corresponding to a hot-water feeding device such as size or length of pipes of a make-up firing circulation circuit 20, inlet water pressure for the circuit 20 so that an obstacle to circulation such as mixture of air can be surely judged even if the judgement is made in a short time. As a result, circulation judgement is surely performed at any time under any conditions and the noise at the judgement can be reduced.

摘要： PURPOSE:To lower undesirable effects on human bodies of users and utilize remaining ozone effectively by sending ozone existing in a filtration bath, a gas-water separator, and a reheating circuit to an ozone generating apparatus by opening on-off valves set respectively in reheating branch circuits. CONSTITUTION:In a sterilizing apparatus A of bathtubs, on-off valves 11 are set respectively in reheating circuits 24 which connect an ozone generating apparatus 12, a filtration bath 4, and a gas-water separator 5 and by opening the switchgears 11, ozone remaining in the filtration bath 4, the gas-water separator 5, and the reheating circuits 24 is sent to the ozone generating apparatus 12. Consequently, while the ozone remaining in the sterilizing apparatus A is reutilized, no ozone is discharged to the atmosphere out of the sterilizing apparatus A. Since reheating is carried out simultaneously during the operation, the remaining ozone in low concentration is converted into oxygen by heating without being sent back to the ozone generating apparatus 12 and thus ozone is not discharged to the bathtub either.

摘要： PURPOSE:To prevent a faulty circulation due to a trouble in the self-suction of a circulation pump when the water level in the bathtub is high enough for the bath water to circulate. CONSTITUTION:The method for preventing a faulty circulation in the water of a bathtub in a forced circulation type bath heater device is to make it possible to circulate the water of the bathtub to a heat exchanger 15 for heating it by a self-suction type circulation pump 14 through a circulation channel 12. At the time of the judgement of circulation, if a water flow detection switch 16 detects no water flow even after operating a self-suction type circulation pump for a specified time, a certain volume of the water from the side of a heat exchanger 17 for supplying hot water that is also provided is poured into the bathtub through a circulation channel and then the self-suction type circulation pump is driven again to detect whether or not there is a water flow.

摘要： PURPOSE:TO provide a method for igniting a gas burner capable of realizing a superior igniting performance in response to gas whatever kind of gas may be supplied. CONSTITUTION:Fuel opening or closing valves V0, V1 of a gas burner 3 are released to open under an air blowing of a blowing fan 1 and an electrical discharge ignition with an igniter 5 is carried out to ignite the gas burner. A method for igniting a gas combustion device is carried out in this manner. Then, in the case that no ignition is carried out even after a specified time elapses from a starting of the igniting operation, an air blowing degree with a blower fan 1 is reduced by a specified rate than that of the present operation so as to perform a re-igniting and an igniting operation at a next operation and at the same time even in case of performing an ignition within a specified period of time, if the ignition is carried out in a time less than a proper predetermined ignition time, a degree of blowing air caused by the blower fan 1 at the next time operation is increased by a specified rate than that of the present time.
