Abstract
The utility model discloses a structure improved constant temperature heater which comprises a shell, the center of which is sunk to form a circular accommodation space and the inner surface of which is provided with a layer of insulation materials; as well as a metal conductor formed by an external frame with circular outer fringes and polygonal inner fringes and an internal frame with polygonal outer fringes and circular inner fringes, wherein the gaps exist between the inner fringes of the external frame and the outer fringes of the internal frame and are kept for PTC heating plates with relative quantity to be arranged inside the accommodation space of the shell, and the internal and external frames are respectively connected with the conductors of the power supply.
Description
The utility model relates to a kind of constent temperature heater, particularly relating to a kind of bubble that cleans easily and gasification is produced rises rapidly, make the abundant convection current of water can quicken heat conduction, and make the structure improved constent temperature heater of the stable performance of PTC heating sheet maximum thermal efficiency.
Fig. 1 is the structural representation of No. 79211915 patent case, and it is based on a kind of PTC heater element 1 with heated at constant temperature characteristic, and mat upper and lower cover body 2a, 2b seal again, and on-line equipment is in water receptacle 3; The installing feature of this case, be to make between its root edge and water receptacle 3 inner bottom surfaces to leave the space, heat simultaneously and be able to upper and lower surface, but in the behaviour in service of reality, because all can form the incrustation scale of white behind the boiling water, the incrustation scale that wherein is deposited on upper cover body 2a surface fortunately cleans, and is deposited on the incrustation scale between its lower cover 2b surface and water receptacle 3 inner bottom surfaces, easy cleaning not then, and can under the situation of accumulating over a long period, influence its thermal conductivity.
In addition, the bubble that the heating of this lower cover 2b surface is produced, because of itself buoyancy is stopped by lower cover 2b, so that it is more of a specified duration to rest on the surface time, and the heat conduction on obstruct water and lower cover 2b surface, cause inner PTC heater element 1 resistance increasing, electric current to diminish, and then power output is diminished, and the electric current instability; In addition, when of a specified duration, bubble can strengthen bubble in the lower cover 2b surface time of staying, easily mislead user's water and seethe with excitement, the time and the mistake drink.
In addition, the gasification bubble that the heating of lower cover 2b surface is produced, must outwards move and to rise then, but because 1700 times when being about liquid state of the volume after the aqueous vaporization, so when water reaches boiling point and gasifies, the lasting a large amount of bubbles that produced will form great buoyancy its lower cover 2b is impacted, and make whole water receptacle 3 produce the defective of shake.
Main purpose of the present utility model is to provide a kind of structure improved constent temperature heater, make do not have between itself and the water receptacle cleaning less than the dead angle, just help keeping of thermal conductivity easily and clean, and have the defective that can not make the water receptacle shake because of the bubble that gasification is produced.
A purpose more of the present utility model is to provide a kind of structure improved constent temperature heater, it is with the contour structures of housing, the bubble that is produced can be risen rapidly, it is too of a specified duration can not rest on the surface, make the abundant convection current of water, quicken heat conduction, and can make the efficiency of heating surface of the stable performance maximum of inner PTC heating sheet.
The purpose of this utility model is realized by following technical scheme.According to a kind of structure improved constent temperature heater that the utility model proposes, it includes: a housing, and its central indent and form annular accommodation space, and be provided with one deck insulation material in inner surface; An and metallic conductor, it is the outrigger by a circular outer rim and polygon inner edge, and the internal frame positive and negative electrode structure that collocation is formed of polygon outer rim and a circular inner edge, the PTC heating sheet of some is installed in outrigger inner edge and the outer intermarginal gap of leaving of internal frame, outrigger, internal frame, PTC heating sheet all are arranged in the accommodation space of this housing, and internal frame, outrigger connect power lead respectively.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid structure improved constent temperature heater, the outrigger of wherein said metallic conductor disconnect it on one side, and connect power lead voluntarily.
Aforesaid structure improved constent temperature heater, wherein said housing is provided with bottom flange, and combines with water receptacle base formation crimping or solid welding, and is installed in the water receptacle.
Aforesaid structure improved constent temperature heater, wherein said housing bottom add underseal lid.
The utility model compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, between structure improved constent temperature heater setting of the utility model and water receptacle, do not clean the dead angle fully, so it is very thorough that the work of cleaning can be carried out ground, the incrusted deposit that destroys thermal conductivity is surely not arranged, therefore can improve thermal effect, not only power saving but also raise the efficiency; And the bubble that is produced during gasification, its top does not have any stopping, hinders it to rise, so can solve the defective of aforementioned patent case.The bubble that is produced is risen rapidly, make the inner acceleration of water receptacle convection current, it can fully be contacted with housing, quicken heat conduction efficiency; Moreover the bubble time of staying is shorter, can not intercept the heat conduction of surface of shell and water, so just can give full play to the stable heat efficiency of PTC heating sheet.
In sum, the structure improved constent temperature heater of the utility model, it is had large improvement technically, and has produced handy and practical effect, and has the effect of enhancement really, thereby is suitable for practicality more, really is a new and innovative, progressive, practical new design.
Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.
