PURPOSE:To contrive to enhance the heat exchange efficiency of the titled exchanger by heightening the circulating speed of bathwater by a structure wherein a water conduit pipe to prevent an inlet and an outlet from short-circuiting is provided on either one of the inlet and the outlet of bathwater. CONSTITUTION:The bathwater fully contacts with a heat exchanger 4 with no short-circuiting of the bathwater between the inlet and the outlet of the bathwater by providing a water conduit pipe 11, the tip of which breaks deeply in the interior of a heat exchange tank 3, on either one of the inlet and the outlet of the bathwater. Accordingly, the improvement of heat-exchanging speed is made possible by increasing the circulating speed of the bathwater. In addition, the water conduit pipe 11 can be used for cleaning the interior of the heat exchange tank 3, because the tip of the pipe 11 breaks deeply in the interior of the heat exchange tank 3. In this case, a flexible water conduit pipe 12 is especially effective, because the tip of the pipe shifts. |
