The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment of the present utility model: this water heater comprises the heating cabinet 9 that the aluminum metal making is installed in metal shell 1, the metal shell 1; Water inlet pipe 6 connects three-way pipe 7, and three-way pipe 7 connects an end and the cold water pipe 20 of metal short tube 13, and cold water pipe 20 connects commercially available temperature probe 17 backs and connects cold water outlet pipe 22; The other end of metal short tube 13 places in the heating cabinet 9, electrically heated calandria 11 is installed in the heating cabinet 9, connect external 220V power supply 19 after the calandria 11 connecting circuit control boxes 16, an end of hot-water line 12 is installed in the METAL HEATING PROCESS storehouse 9, the other end connects hot water outlet pipe 21 after connecting commercially available water flow sensing unit 18.For commercially available water inlet filter 8 is installed on the impurity in the filtered water, the water inlet pipe 6, several radial holes 14 are arranged on the short tube 13 in this product, also have end cap 15 at short tube 13 end faces; Cold water can flow out from radial hole 14, and the speed of having slowed down the current that enter heating cabinet 9 has improved the efficient to the water heating.The commercially available water filter 5 that goes out is installed on the hot water outlet pipe 21 in this product.The electric heating body 11 that product uses among the embodiment is made up of tungsten filament 23, pole plate 24 and the lead 25 of outsourcing heating material; The heating position of calandria 11 is provided with and connects cover plate 2 and pressing plate 3, connects on the calandria 11 between cover plate 2 and the pressing plate 3 sealing ring 4 is housed, and connects cover plate 2 and pressing plate 3 usefulness screws 10 and is connected and fixed; Heating material in the calandria 11 can adopt titanium nitride or silicon nitride material to make.
