Description
Technical field
The present invention relates to air source electric heater, relate generally in electric heater, used is immersed in the non-metallic pipe in water the electrothermal tube having heating wire.
Background technology
It is currently used for the electrothermal tube in air source 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 air source electric heater is improved.
The technical measures of the present invention are: water tank is by metal or nonmetal making, built with the electrothermal tube 11 having heating wire in non-metallic pipe；Outlet pipeline is provided with the out-of-date fast heating device 20 i.e. adding hot water of current；Described electrothermal tube is built with heating wire 3 and magnesium oxide powder or air 4 at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 at the two ends of heating wire and passes through nonmetal plug 6, outside protruded tube, in becoming non-metallic pipe, have the electrothermal tube 11 of heating wire；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, have the electrothermal tube 11 of heating wire in becoming non-metallic pipe；Described heating wire 3 is installed in dry combustion method in air in non-metallic pipe 7 or 8；Pipe in pipe outside air communicate.
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 air source electric heater to use inside the Pass nonmetal has the electrothermal tube of heating wire, is immersed in water not scaling, and heating corrodes never and punctures, and will not leak electricity.
Accompanying drawing explanation
Fig. 1 is that two ends have eduction rod, has the electrothermal tube of heating wire in non-metallic pipe；
Fig. 2 to Fig. 4 is that one end has eduction rod, has the electrothermal tube of heating wire in blind hole non-metallic pipe；
Fig. 5 to Fig. 7 has the air source electric 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: eduction rod or have 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, the out-of-date i.e. water-heating device 20 of current in claiming 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, have the container 21 of intake-outlet, air source main frame 22.
Fig. 1 to Fig. 4 is one end filled in central 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, 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.
For realizing double insulation, one layer of non-metallic pipe can be set between heating wire 3 and non-metallic pipe 7 or 8 again.
Fig. 5 to Fig. 7 has the structure chart of the air source Water tank for electrical water heater 15 of the electrothermal tube 11 of heating wire in being equipped with non-metallic pipe, outlet pipeline is provided with the out-of-date i.e. water-heating device 20 of current, being equipped with electrothermal tube 11 in the container 21 have intake-outlet, during water outlet, electrothermal tube must be connected；Air source main frame 22 in figure, can be independently arranged, it is also possible to be combined into one with water tank, this kind of air source water heater is applicable to any cold climate conditions, when cop ＞ 2 with air source main frame 22, heating, as cop ＜ 1.5, automatic replacing electrothermal tube works.
