Embodiment 1
[0015] See attached Figure 1-2 , with a metal heat-conducting sealed shell sandwich type electric heating film plate electric water heater, consisting of an insulating heat-conducting plate 1, an electric heating film 2, an insulating and isolated heat-dissipating layer 3, a metal heat-conducting sealed shell 4 and a power supply wire 5. The insulating heat conducting plate 1 is made of porcelain plate material with good insulating performance, strong thermal conductivity and high thermal vibration performance. The length of the porcelain plate is 300 mm, the width is 300 mm, and the thickness is 6 mm. A layer of electric heating film 2 is sprayed at a high temperature on one surface of the insulating heat conducting plate 1, and the material of the electric heating film 2 adopts the prior art. The two sides of the electrothermal film 2 are provided with conductive strips 6 respectively, and the length of the conductive strips 6 is equal to the length of the sides of the ele...

The invention discloses a sandwiched electro-thermal film plate electric water heater with metal heat-conduction sealing shells. The sandwiched electro-thermal film plate electric water heater is composed of insulated heat conduction plates, electro-thermal films, an insulated and isolated heat radiation layer, metal heat-conduction sealing shells and power supply wires. One surface of each insulated heat conduction plate is sprayed with one electro-thermal film at high temperature. The two sides of the electro-thermal films are respectively provided with a conductive strip, and the end of each conductive strip is connected with one power supply wire. The surfaces, with the electro-thermal films, of the two insulated heat conduction plates of the same specification are arranged face to face to form the insulated and isolated heat radiation layer, and the insulated and isolated heat radiation layer is filled with ceramic powder. The metal heat-conduction sealing shells are arranged at the peripheries of the two insulated heat conduction plates. The electric water heater is submerged in a water tank, an alternating-current power supply is started, the electro-thermal films immediately start heating, and the insulated heat conduction plates and the metal heat-conduction sealing shells quickly transmit heat energy to perform heating. Full-range water heating is achieved, the heating area is large, heat conduction and temperature rise are quick, no noise is generated, and an energy-saving effect is achieved.
Description
technical field [0001] The invention relates to an electric heating film electric water heater, in particular to a sandwich type electric heating film plate electric water heater with a metal heat conducting sealed shell. Background technique [0002] An electric water heater using an electric heating film as a heat source, one is a cylindrical electric heating film tube heating device, such as the structure named "a water storage water heater" disclosed in the utility model patent of the Chinese Patent Publication No. CN2018280092U, in the water tank A cylindrical electrothermal film tube is arranged on the outside, and cold water flows through the cylindrical electrothermal film tube to be heated. The disadvantage of the above structure is that when the cylindrical electrothermal film tube is arranged outside the water tank to generate heat, part of the heat energy is lost in the air, and the thermal efficiency is low. The other is a flat plate-shaped electric heating fil...
