PURPOSE:To generate powerful water discharge and to easily clean a heat exchanger by fastening a hose end having a water discharge port of a specified diameter to one end of a hose having the other end connectable to a hot-water tap, and fixing a connecting nut rotatably to the hose end. CONSTITUTION:The hose end 8 having the water discharge port 9 of a specified diameter is fastened to one end of the hose 7 having the other end connectable to a hot-water tap, and the connecting nut 5 is rotatably provided to the hose end. In addition, a screw 2 and a handle 1 are provided in parallel in place of the discharge port 9, and a nozzle with the water discharge port 4 formed at its center is screwed into the connecting nut 5. The connecting nut fits the connecting screw of a commercially available shower head. When the diameters of the discharge ports 9 and 4 are reduced to 6-7mm, water can be sufficiently powerfully discharged, and the heat exchanger is easily cleaned. When the shower is screwed to a cleaning nut, the device can be used as a shower device. |
