Description

A kind of overflow-type electric heater
Technical field
The utility model relates to a kind of overflow-type electric heater, the overflow-type electric heater that a kind of specifically electric heating tube can clean.
Background technology
At present, the needs that known traditional electrical heating tube uses for reality are processed into shape miscellaneous, on the one hand such as " U " shape, " returning " font, spirality or the like when making." U " shape and spirality electric heating tube are used for adding hot water and wet goods medium more, and " returning " font electric heating tube not only can add hot water, wet goods medium, but also can heated air.No matter the kind of the shape of electric heating tube and medium how, the purpose of its making is nothing more than 2 points: the two poles of first heating tube is located at same end, brings convenience to the terminal use; It two is in order to increase the length of heating tube in limited usage space, to increase the required area of dissipation of its heating power.Because the restriction of materials used mechanical performance and manufacture craft level has waste product to produce in the time of in the processing and making process of reality, brought very big loss to enterprise.On the other hand, when the electric heating tube of making used in water and wet goods medium, when especially using in drinking water, its surface scale was difficult to avoid, and used its scale formation more outstanding in the harder area of water quality.Traditional immersion electric heating tube is difficult to solve the problem of cleaning hot courage and electric heating tube, up to the present, does not also have good way to address this problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, a kind of overflow-type electric heater is provided, can not only solve the technological problems when making electric heating tube, and can realize that the convenient of electric heating tube and hot courage cleans, thereby solve the problem of electric heating tube and the easy fouling of hot courage.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of overflow-type electric heater, comprise miniature hot courage and place the interior electric heating tube of miniature hot courage, it is characterized in that: described electric heating tube is straight type pipe, it comprises shell and places the interior earthenware of shell, earthenware is around with heating wire, ceramic cap is stamped at the top of shell, the bottom of shell embeds ceramic blanket, draw internal wiring terminal and outer terminal on the described ceramic cap, described internal wiring terminal passes the inner core of earthenware and is connected with an end of heating wire, described outer terminal is connected with the other end of heating wire, inserted the interior magnesium oxide filler of filling of shell of content, be provided with the viscous flow helical casing between miniature hot courage and the electric heating tube, on miniature hot courage, the both ends of viscous flow helical casing are provided with water inlet and delivery port respectively.
Technical solution adopted in the utility model also comprises:
Be positioned at an end fixedly connected one threaded flange of ceramic cap on the shell of described electric heating tube, described flange is threaded with miniature hot courage through a high-temperature seal ring.
Described earthenware outer surface has the spiral form groove, and heating wire is around in the spiral form groove.
Be fixed with the thermostat support on the described miniature hot courage.
The afterbody of described internal wiring terminal embeds the refractory ceramics pad.
Described miniature hot courage is a stainless steel casing.
The shell of described electric heating tube is a stainless steel casing.
Described viscous flow helical casing is a stainless steel sleeve.
Because the utility model has been taked above-mentioned technical measures, it compared with prior art has following advantage:
1, electric heating tube is type pipe always, has solved the technological problems of Bending Processing really;
2, the lead-in wire of electric heating tube is drawn from an end, has solved terminal use's assembly problem;
3, electric heating tube not only is type pipe always, and lead-in wire draws from an end, can make the electric heating tube microminiaturization may well;
4, the overflow-type electric heater has been realized one-time heating, has solved thousand boiling water problems;
5, the overflow-type electric heater makes cleaning electric heating tube and hot courage convenient flexibly owing to used being threaded of port, has solved easy incrusted problem.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment electric heating tube.
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
See figures.1.and.2 threaded flange 2, thermostat support 3, miniature hot courage 4, viscous flow helical casing 5 that the utility model comprises electric heating tube 14, high-temperature seal ring 1, is welded with electric heating tube 14.The shell of miniature hot courage, electric heating tube, the equal available metal material of the material of viscous flow helical casing, the most handy stainless steel material is made.Viscous flow helical casing 5 places in the miniature hot courage 4, electric heating tube with 2 welding of threaded flange after high-temperature seal ring 1 with in viscous flow helical casing 5 is housed miniature hot courage 4 be threaded.Thermostat support 3 is welded with miniature hot courage 4 shells, is used for installing temperature control device.Electric heating tube 14 is straight type pipe, and electric heating tube 14 comprises electric heating tube shell 6, high temperature resistant spiral form earthenware 7, outer terminal 8, internal wiring terminal 9, refractory ceramics lid 10, magnesium oxide filler 11, heating wire 12, refractory ceramics pad 13.Earthenware 7 outer surfaces have the spiral form groove, and heating wire 12 is around in the spiral form groove.Internal wiring terminal 9 passes the inner core of high temperature resistant spiral form earthenware 7, and is connected with the end overlap joint spot welding of heating wire 12.Outer terminal 8 is connected with the other end overlap joint spot welding of heating wire 12.The afterbody of internal wiring terminal 9 embeds refractory ceramics pad 13 and is placed on the electric heating tube shell 6.Magnesium oxide filler 11 is filled in the electric heating tube shell 6 of inserting content.Refractory ceramics lid 10 through solid seal glue apply and internal wiring terminal 9, outer terminal 8 runs through with after with the electric heating tube shell 6 of inserting content in be connected.On miniature hot courage 4, the both ends of viscous flow helical casing 5 are provided with water inlet 16 and delivery port 15 respectively.
