Abstract
A kind of polycyclic shape Electrothermic film liquid heater, including heating container and polycyclic shape electrothermal film heater, the polycyclic shape electrothermal film heater with heating container bottom by sintering two or more concentric circles annular Electric radiant Heating Films into and two current electrodes symmetrical with circular ring shape Electric radiant Heating Film center of circle radially opposite sides are formed.Using two rings or the above Electric radiant Heating Film of two rings, annulus Electric radiant Heating Film radial width is gradually reduced in ecto-entad, and the power density of inner ring Electric radiant Heating Film is made to tend to be balanced with the power density of outer shroud Electric radiant Heating Film, not by heating container（Especially glass electric kettle）The non-uniform influence of bottom interior thickness, extends the service life of Electric radiant Heating Film.
Description
Technical field
The utility model is related to a kind of liquid heating, especially a kind of polycyclic shape electrothermal membrane type liquid heating.
Background technology
The Electric radiant Heating Film of existing electrothermal film electric hot-water bottle designs unreasonable, and the Electric radiant Heating Film shape that bottom of the pot portion is covered with is one whole
Body it is round or rectangular, symmetrical both sides be equipped with electrode, the material of entire Electric radiant Heating Film each section is identical with manufacture craft, therefore resistance
Value should be relatively uniform, but the flatness of glass pot bottom center portion and thickness are all bad, so the one of Electric radiant Heating Film
Cause property is very poor, and difficulty of processing is big, and yield rate is low, and power density is uneven to be easy to cause local damage.
Invention content
In order to overcome the drawbacks described above of the prior art, the utility model to provide a kind of polycyclic shape Electrothermic film liquid heater,
Keep properties of product reliable and stable, prolong the service life length.
The utility model solve above-mentioned technical problem design scheme be：A kind of polycyclic shape Electrothermic film liquid heater, packet
Include heating container and polycyclic shape electrothermal film heater, it is characterized in that the polycyclic shape electrothermal film heater by with heating container bottom
Sinter two or more concentric circles annular Electric radiant Heating Films and symmetrical with circular ring shape Electric radiant Heating Film center of circle radially opposite sides into
Two current electrodes are formed.
The interior annular film surface radial width of described two concentric circles annular Electric radiant Heating Films is heating container bottom disc radius
0.5~0.6, outer toroid film surface radial width is heat container bottom disc radius 0.7~0.9, interior annular film and outer toroid
The radial spacing of film is heat container bottom disc radius 0.1~0.2.
The interior annular film surface radial width of three concentric circles annular Electric radiant Heating Film is heat container bottoms radius of circle 0.4
~0.5, middle circle film surface radial width is heat container bottom disc radius 0.55~0.7, and outer toroid film surface is radially-wide
Degree is the 0.75~0.95 of electric-heating container bottom disc radius, and the radial spacing between two annulus film surfaces is electric-heating container bottom
The 0.05~0.06 of disc radius.
Described two current electrodes are that radial upper and lower both sides are symmetrical with the circular ring shape Electric radiant Heating Film center of circle.
Described two current electrodes are that diameter is symmetrical to the left and right sides with the circular ring shape Electric radiant Heating Film center of circle.
The advantageous effect of above-mentioned design is, annulus is gradually reduced using two rings or the above Electric radiant Heating Film of two rings, ecto-entad
Electric radiant Heating Film radial width makes the power density of inner ring Electric radiant Heating Film tend to be balanced with the power density of outer shroud Electric radiant Heating Film, is not heated
Container（Especially glass electric kettle）The non-uniform influence of bottom interior thickness, extends the service life of Electric radiant Heating Film.
Description of the drawings
Fig. 1 is the annular Electric radiant Heating Film structural schematic diagram of electric kettle two.
Fig. 2 is the annular Electric radiant Heating Film structural schematic diagram of liquid electric heater three.
Specific implementation mode
It is described in reference diagram 1, electric hot water kettle body 1, electric kettle bottom surface 2, circular ring shape Electric radiant Heating Film 3, current electrode 4.Wherein, circle
Annular Electric radiant Heating Film 3 is made of two donut Electric radiant Heating Films, the 31 film surface radial width of interior annular of two donut Electric radiant Heating Films
To heat the 0.5~0.6 of 2 disc radius R of container, that is, electric kettle bottom surface, 33 film surface radial width of outer toroid is electric kettle bottom
The radial spacing of the 0.7~0.9 of 2 disc radius R of face, interior annular film 31 and outer toroid film 33 is heating container, that is, electric kettle bottom
0.1~0.2. current electrodes 4 of 2 disc radius R of face are that radial upper and lower both sides are symmetrical with circular ring shape Electric radiant Heating Film 3.Current electrode
Two groups of annular hotting mask connection power supplies.
Shown in Fig. 2, electric-heating container 1 can be that electric kettle is alternatively the larger liquid heater of other volumes,
Electrical heating bottom disc 2, circular ring shape electric heating film 3 and current electrode 4.Wherein circular ring shape Electric radiant Heating Film 3 includes 3 donut electric heating
Film, 31 film surface radial width of interior annular are the 0.4~0.5 of 1 bottom surface radius of circle R of electric-heating container, and 32 film surface of middle annulus is radially-wide
The 0.55~0.7 of the 1 bottom surface radius of circle R of electric-heating container of degree, 33 film surface radial width of outer toroid are 1 bottom disc of electric-heating container
The 0.75~0.95 of 2 radius R, between two annulus film surfaces radial spacing be electric-heating container bottom disc radius R 0.05~
0.06.Two current electrodes 4 are that the radial left and right sides is symmetrical with circular ring shape Electric radiant Heating Film 3, and current electrode 4 is three groups of annular electric heating
Film is connected power supply.
31 length of run of interior annular Electric radiant Heating Film is most short, so the most narrow of width setting, resistance is made to increase.Middle annulus electric heating
32 length of run of film is longer, the wider of width setting, resistance is made to reduce.33 length of run longest of outer toroid Electric radiant Heating Film, so
The most wide of width setting, keep resistance minimum.Work under identical operating voltage so just can make in, in, outer shroud electric heating
The power density of film tends to be balanced, can extend the service life of Electric radiant Heating Film.
