Claims

[Scope of Claim for Utility Model Registration] (1) A system connected to a bathtub via a circulation pipe and equipped with a circulation pump, a heater, and a filter in a hot water channel, where the circulation pump forcibly circulates hot water in the bathtub through the circulation channel. In a bath circulation water heater configured to heat water to a predetermined temperature using a heater, the following (a)
A circulating water heater for a bath, characterized by having the configurations of ) to (d). (a) A cylindrical case whose top end is closed with an openable lid, a hot water pipe extending vertically inside the case, and a through hole through which the hot water pipe passes vertically. and a filter disposed inside the case so as to be able to be pulled out above the case. (b) the filter includes a sheet-like filter element;
The sheet-like filter element is composed of a granular filter element, and the sheet-like filter element has a cylindrical filter paper attached to the upper surface of a bottom plate that is not water-permeable, and a hot water pipe is connected to an upper opening inside the cylindrical filter paper. (c) The hot water pipe is connected to the discharge side of the circulation pump, and the hot water sucked in from the bathtub by the circulation pump is sent to the inner upper opening of the sheet-like filter element. (d) Foreign matter contained in the hot water is filtered and deposited inside the sheet-like filter element. (2) The circulating water heater for a bath according to claim 1, wherein the filter paper of the sheet-like filter element is folded into a corrugated shape to form a cylindrical overall shape. (3) The circulating water heater for a bath according to claim (1), wherein the filter paper of the sheet-like filter element is paper made from natural or synthetic pulp, nonwoven fabric, or woven fabric.
