Abstract:
A shower heating device comprising:a tube folded upon itself multiple times and having multiple water paths defined by baffles made of heat conductive material therein, an inlet, and an outlet; a first converging area provided at a joint between said tube and said inlet to cause an eddy effect to water flowing into said tube, said first converging area is a tube-like area and is oriented in a direction perpendicular to said inlet and perpendicular to a direction of flow of the water in said tube, said inlet being located at a longitudinal midpoint of said first converging area; a second converging area provided at a joint between said tube and said outlet to cause an eddy effect to heated water flowing out of said tube, said second converging area is a tube-like area and is oriented in a direction perpendicular to said inlet and perpendicular to a direction of flow of the heated water flowing out of said tube; a plurality of semiconductor heating elements each being positioned adjacent to one of said paths to heat the water; a plurality of pairs of electrical plates, each said pair of electrical plates having one of said semiconductor heating elements sandwiched therebetween; a plurality of pairs of insulation plates, each said pair of insulation plates having one of said pairs of electrical plates received therebetween; and a nut provided on both said inlet and said outlet so as to allow said inlet and said outlet to be connected to a hose.
