Abstract
Vertical water storage formula electric water heater who has electrothermal tube of heating wire in non -metallic pipe is equipped with, the shell of electrothermal tube is non -metallic material, and it is in through type or blind hole non -metallic pipe (7) or (8) that its one end or two ends have the electrothermal tube of drawing stick (1), is equipped with heating wire (3), draws stick (1) in addition and stretches to the outside of tubes through nonmetal end cap (6), heating wire (3) are dress dry combustion methods in the air in non -metallic pipe (7) or (8), open the end lower part in direct non -metallic pipe (7) or blind hole non -metallic pipe (8) simultaneously, are equipped with circuit breaker (12), the circuit breaker is that one end is two exposed and keep apart wires, and the other end and control circuit board's controlling element is connected, meets water simultaneously when two wires and switches on, just infories controlling element, and messenger's circuit breaks off.
Description
Technical field
The present invention relates to vertical water storage type electric water heater, relate generally in electric heater, used is immersed in the non-metallic pipe in water the electrothermal tube having heating wire.
Background technology
The electrothermal tube being currently used in electric heater, 95% 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 vertical water storage type electric water heater is improved.
The technical measures of the present invention are that the water tank of vertical water storage type electric water heater is by metal or nonmetal making, electrothermal tube 11 built with there being heating wire in non-metallic pipe: be built with heating wire 3 and magnesium oxide powder or air 4 at straight-through non-metallic pipe 7, and heating wire 3 is fixed in non-metallic pipe 7, eduction rod 1 is installed by nonmetal plug 6 at the two ends of heating wire, outside protruded tube, become non-metal shell electrothermal tube 11；Or at one end close and become blind hole non-metallic pipe 8 built with heating wire 3 and magnesium oxide powder or air 4；Eduction rod 1 is installed at the two ends of heating wire 3, and heating wire 3 is bent to U-shaped in pipe, make two eduction rods 1 at one end, by nonmetal plug 6 protruded tube outside, be formed as non-metal shell electrothermal tube 11；Described heating wire 3 is dry combustion method in the air in non-metallic pipe.
Simultaneously 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, when two one metal wires simultaneously suffer water conducting, note that control element, 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 the vertical water storage type electric water heater equipped with the electrothermal tube having heating wire in non-metallic pipe, be immersed in water not scaling, electrothermal tube corrodes never and punctures, and will not leak electricity.
Accompanying drawing explanation
Fig. 1 is the electrothermal tube having heating wire in two ends have the non-metallic pipe of eduction rod；
Fig. 2 to Fig. 4 is the electrothermal tube having heating wire in blind hole non-metallic pipe；
Fig. 5 to Fig. 7 has the vertical storage-type electric water heater structural representation of the electrothermal tube of heating wire in being equipped with non-metallic pipe；
Detailed description of the invention
In accompanying drawing, in eduction rod or title terminal 1, sealing ring or high-temp glue 2, heating wire 3, magnesia powder or air 4, nonmetal plug 6, straight-through non-metallic pipe 7, blind hole non-metallic pipe 8, heater 9, non-metallic insulation spacer 10, non-metallic pipe, there are the electrothermal tube 11 of heating wire, chopper 12, metal or nonmetal water tank 15, shell 16, blind flange 17, mounting seat 18, friction top 19.
Fig. 1 to Fig. 4 is one end filled in vertical water storage type electric water heater or two ends have eduction rod use non-metallic pipe in have the electrothermal tube of heating wire, there is nonmetal plug 6 termination, and eduction rod 1 is by outside plug 6 protruded tube.There are 1 or above heating wire 3 in non-metal shell, between heating wire, have non-metallic insulation thing 10 to be isolated；In non-metal shell, having magnesia powder or non-metallic insulation thing or air 4, what Fig. 4 heating wire often enclosed be relatively large in diameter can press close to tube wall.
Due to heating wire 3 can dry combustion method in atmosphere, therefore can be directly installed in non-metal shell, if fill with magnesia powder, the position of heating wire will not be moved.
Fig. 5 to Fig. 7 is vertical electric water heater with water tank structure chart, and water tank 15, built with electrothermal tube 11, is water outside it, 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 puncturing, Fig. 5 is single water tank, and Fig. 6, Fig. 7 are double water tank.
For realizing double insulation, one layer of non-metallic pipe can be set between metal or non-metal electric heating silk 3 and non-metallic pipe 7 or 8 again.
Claims (2)
