HEAT SOURCE DEVICE, DRAIN DISCHARGE SYSTEM, DRAIN DISCHARGE PROGRAM AND DRAIN DISCHARGE METHOD

摘要

PROBLEM TO BE SOLVED: To automate drain discharge that is caused by heat exchange of a heat source machine.SOLUTION: In a heat source device (a heat source machine 6 and a hot water supply/after-burning device 30), drain outlets (8 and 64) comprise drain plugs (10 and 52-8) that are automatically opened when draining bathtub water (BW), hot water can be supplied to bathtubs (4 and 60) from which the bathtub water can be automatically drained, and the drain caused by the heat exchange is discharged via at least the bathtubs (4 and 60). Drain discharge systems (2-1 and 2-2) include the heat source device. The heat source device or the drain discharge systems comprise: drain tanks (20 and 58) in which the drain is stored; and drain flow channels (22 and 54-3) which cause the drain to flow from the drain tanks into the bathtubs when discharging the drain. When the drain plugs are opened, the drain is caused to flow from the drain tanks through the drain flow channels into the bathtubs and the drain is discharged together with drainage of the bathtub water.SELECTED DRAWING: Figure 1
