Description

Use the quick-heating type electric water heater of non-metal shell electrothermal tube

Technical field

The present invention relates to quick-heating type electric water heater, relate generally in electric heater, the non-metal shell electrothermal tube being immersed in water used.

Background technology

The electrothermal tube being currently used in electric heater, 100% is the tubular electrothermal element produced by technical standard JB/T4088-1999 " daily tubular electrothermal element " or JB/T2379-1993 " tubular metal electric heating element ", be " with metal tube as shell, heating alloy make heater; at one end or two ends have eduction rod; load closely knit magnesium oxide powder dielectric in metal tube, with the element of fixing heater；" it is the existing heating commonly used；This metal shell heating, is completely sunk in the water, after long-time use, meeting scaling, reduces heating efficiency, and corrosion punctures, and makes water charged, is world-famous puzzle.

Summary of the invention

It is an object of the invention to existing quick-heating type electric water heater is improved.

The technical measures of the present invention are that water tank uses metal or nonmetal making, the electrothermal tube that water tank is used built with non-metal shell electrothermal tube 11:

Be built with heating wire 3 at metal tube 5, with magnesium oxide powder 4, metal tube 5 and heating wire 3 carried out isolated insulation, the two ends of heating wire install eduction rod 1, by nonmetal plug 6 protruded tube outside；Become heater 9；Then heater 9 is contained in non-metallic pipe 7, is formed as non-metal shell electrothermal tube 11；Or at metal tube 5 built with heating wire 3, with magnesium oxide powder 4, metal tube 5 and heating wire 3 are carried out isolated 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, being formed as heater 9, then heater 9 is contained in one end closing becomes in blind hole non-metallic pipe 8, air 4 or insulant 10, in unlimited one end, blind hole non-metallic pipe 8 and heater 9 are fixed, be formed as non-metal shell electrothermal tube 11；Or in blind hole non-metallic pipe 8, loading electrothermal tube, described electrothermal tube is carbon fiber pipe or halide torch or non-metal shell electrothermal tube or dry combustion method electrothermal tube, and by the eduction rod 1 in blind hole one end, bending is turned back to the other end and is made eduction rod in same one end, and there is support pads at electrothermal tube two ends.

In straight-through non-metallic pipe 7 or blind hole non-metallic pipe 8 open end bottom, equipped with chopper 12, described chopper, be one end be two tinsels that are exposed and that isolate, the other end is connected with the control element of control circuit plate, note that control element when two one metal wires simultaneously suffer water conducting, make circuit disconnect.

Described non-metallic pipe 7 or 8, first-selected quartz glass tube, either blind hole pipe or straight pipe, internal heating wire has one or more, isolates with non-metallic insulation thing 10, prevent short circuit between heating wire.

The invention has the beneficial effects as follows that quick-heating type electric water heater uses non-metal electric heating pipe, be immersed in water not scaling, heating corrodes never and punctures, and will not leak electricity.

Accompanying drawing explanation

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

Fig. 2 is that one end has eduction rod, outside metal tube 5, and the also electrothermal tube of blind hole non-metal shell 8；

Fig. 3 is the blind hole non-metal shell 8 structure chart built with electrothermal tube；

Fig. 4 is equipped with instantaneous water heater's structural representation of non-metal shell electrothermal tube；

Fig. 5 to Fig. 7 is equipped with instantaneous water heater's structural representation of non-metal shell electrothermal tube；

Detailed description of the invention

In accompanying drawing, eduction rod or title terminal 1, sealing ring or high-temp glue 2, heating wire 3, magnesia powder or non-metallic insulation thing or air 4, metal tube 5, nonmetal plug 6, straight-through non-metallic pipe 7, blind hole non-metallic pipe 8, heater 9, non-metallic insulation spacer 10, non-metal shell electrothermal tube 11, chopper 12, metal or nonmetal water tank 15, shell 16.

Fig. 1 to Fig. 3 is the non-metal shell electrothermal tube that one end filled in quick-heating type electric water heater or two ends have eduction rod, there is nonmetal plug 6 termination, eduction rod 1 is by, outside plug 6 protruded tube, having 1 or above heating wire 3, have non-metallic insulation thing 10 to be isolated between heating wire in non-metal shell；In non-metal shell, there are magnesia powder or non-metallic insulation thing or air 4.

Fig. 3 is to be straight-through non-metallic pipe 7 at blind hole non-metallic pipe 8, Fig. 4, and interior loading non-metal electric heating pipe 11, described non-metal electric heating pipe refers to carbon fiber pipe or halide torch or ceramic package electrothermal tube；Described metal electric heating pipe has heating wire in referring to metal tube, is insulated with metal pipe-wall by heating wire with magnesia powder；This kind of structure, the eduction rod in blind hole one end to bend and to turn back to the other end.

Fig. 5 to Fig. 7 is quick-heating type electric water heater structure chart, and Fig. 5 water tank holds little, and current are out-of-date i.e. to be heated water；Fig. 6, Fig. 7 water tank capacity is relatively big, when summer or spring and autumn, sky discharged water, immediately heats the water released the electrothermal tube near outlet pipe；Winter, temperature was low, the electrothermal tube of water inlet pipe preheat the water in water tank, when discharging water, then heated the water being pre-heated to 40～65 DEG C once；Water tank 15, built with electrothermal tube 11, is water outside it, and the shell of this electrothermal tube is made up of nonmetal, and there are heating wire and the isolation of water glass, never scaling in inside, never punctures；Diagram uses Fig. 3 Fig. 4 electrothermal tube, it is possible to changes structure and uses through type Fig. 1 or Fig. 4 electrothermal tube.
