PURPOSE:To evenly distribute the incoming hot water from a water inlet by employing a three dimensional frame structure made of continuous foam material such as polyurethane foam that has a relatively large porosity or that which is left after removing the foam film of continuous foam material as a three dimensional structure of water duct. CONSTITUTION:The exterior is sealed by a water-repellent sheet 13, and a water inlet 11 and a water outlet 12 are provided. The water duct part comprises a three dimensional frame structure 15 made of continuous foam material having a large porosity or that which is left after removing the foam film of the continuous foam material. For such a three dimensional structure, urethane foam of polyester family or urethan foam of polyester family can be employed. Further, the water flow resistance can free be changed by forming protuberance 17 on the inside of the outer cover 13 or by forming channels 16. |
