Abstract

The invention provides a horizontal single-liner water storage type electric water heater adopting non-metal shell electric heating tubes. Shells of the electric heating tubes are made of non-metal materials. The electric heating tubes are provided with cold leads (1) at one ends or at both ends, and the electric heating tubes are installed in a straight-through type non-metal tube (7) or a blind hole non-metal tube (8) and provided with the electric heating tubes. The electric heating tubes are carbon fiber tubes or halogen tubes or the non-metal shell electric heating tubes or dry electric heating tubes. The cold leads (1) extend to the outside of the tube through a non-metal plug (6). Meanwhile, breakers (12) are installed on the lower portion of an open portion of the end of the straight-through type non-metal tube (7) or the blind hole non-metal tube (8).

Description

Using horizontal single courage storage-type electric water heater of non-metal shell electrothermal tube

Technical field

The present invention relates to electric heater, in relating generally to electric heater, being immersed in for being adopted is nonmetallic in water Shell electrothermal tube.

Background technology

The electrothermal tube being currently used in electric heater, 100% is by technical standard JB/T4088-1999《Daily pipe Shape heating》Or JB/T2379-1993《Tubular metal electric heating element》The tubular electrothermal element of production, be " with metal tube as shell, heating alloy make heater, at one end or two ends have eduction rod, in metal tube It is interior to load closely knit magnesium oxide powder dielectric, to fix the element of heater；" existing commonly use Heating；This metal shell heating, is completely sunk in the water, after long-time use, meeting scaling, Heating efficiency is reduced, and corrosion punctures, and makes water powered, is world-famous puzzle.

The content of the invention

The purpose of the present invention is that existing horizontal single courage storage-type electric water heater is improved.

The present invention technical measures be the water tank of horizontal single courage storage-type electric water heater by metal or nonmetallic making, Built with non-metal shell electrothermal tube 11；The non-metal shell electrothermal tube refers to that the shell of electrothermal tube is non-gold Category material makes：It is built with heating wire 3, with magnesium oxide powder 4, by metal in metal or non-metallic pipe 5 Or non-metallic pipe 5 and heating wire 3 carry out isolated insulation, eduction rod 1 is installed at the two ends of heating wire, by non- Outside the protruded tube of metal plug 6, become heater 9；Then heater 9 is mounted in non-metallic pipe 7, and will Non-metallic pipe two ends are fixed with heater, become non-metal shell electrothermal tube 11；Or in metal or nonmetallic Pipe 5 built with heating wire 3, with magnesium oxide powder 4, by metal or non-metallic pipe 5 and heating wire 3 carry out every From insulation, eduction rod 1 is installed at the two ends of heating wire 3, and bends to U-shaped, make two eduction rods at one end, Become heater 9, then heater 9 is mounted in into one end closing becomes in blind hole non-metallic pipe 8, becomes non-gold Category shell electrothermal tube 11；Or in straight-through non-metallic pipe 7 or blind hole non-metallic pipe 8, interior loading electrothermal tube, institute It is carbon fiber pipe or halide torch or non-metal shell electrothermal tube or dry combustion method electrothermal tube to state electrothermal tube, will be in blind hole one end Eduction rod 1, bending turns back to the other end and makes eduction rod in same one end, and there are support pads at electrothermal tube two ends.

Simultaneously in straight-through non-metallic pipe 7 or the open end bottom of blind hole non-metallic pipe 8, equipped with breaker 12, institute Breaker is stated, is the control element that one end is two wires that are exposed and isolating, the other end and control board Connection, when two one metal wires run into water conducting simultaneously control element is noted that, disconnects circuit.

The non-metallic pipe 7 or 8, first-selected quartz glass tube.

The invention has the beneficial effects as follows horizontal single courage storage-type electric water heater adopts non-metal electric heating pipe, water is immersed in In not scaling, heating never corrodes and punctures, will not leak electricity.

Description of the drawings

Fig. 1 is that two ends have eduction rod, outside metal or non-metallic pipe 5, the also electrothermal tube of non-metal shell 7；
