Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is described:

See Fig. 1 to Fig. 3, electricity pottery stove heat-generating disc of the present utility model, comprise the thermal insulating disc seat 1 of circular spill, heater 2 and two male blades 2021 and 2011, this heater 2 is arranged and is fixed on thermal insulating disc seat 1 intracavity bottom in the clockwise counterclockwise alternately mode of turning back from middle part outward, heater 2 forms a scalloped channels 204 from center to outside, and end 202 and the head end 201 of this heater 2 cause scalloped channels 204; As preferred scheme, the end 202 of heater 2 and head end 201 cause the position beyond in the middle part of scalloped channels 204.Two male blades 2021 with 2011 one end be connected with the end 202 of heater 2 and head end 201 respectively, the other end of two male blades 2021 and 2011 passes thermal insulating disc seat 1 bottom side as terminals.

As a kind of improvement project, thermal insulating disc seat 1 bottom side is provided with the lower end of high temperature insulating block 4, two male blade 2021 and 2011 through this high temperature insulating block 4; This high temperature insulating block 4 is preferably refractory ceramics block, because it has good high temperature resistant and thermal insulation.

The one of heat-generating pipe, heating wire or fever tablet that described heater 2 can be made for nickel chromium, is preferably fever tablet, realizes fixing so that embed bottom thermal insulating disc seat 1 inner chamber 101.

Mechanism of heat insulation of the present utility model is as follows: first, two male blades 2021 and 2011 are directly connected through the end 202 of thermal insulating disc seat 1 and heater 2 and head end 201, two male blades 2021 and 2011 and thermal insulating disc seat 1 closely cooperate, and effectively prevent heat from the clearance leakage between inserted sheet 2021 and 2011 and thermal insulating disc seat 1; Secondly, in thermal insulating disc seat 1 bottom side, high temperature insulating block 4 is set, two male blades 2021 and 2011 are just connected with the head end 201 of heater 2 and end 202 through high temperature insulating block 4 and thermal insulating disc seat 1 successively, can intercept further and transmit heat out from male blade 2011 and 2021; Again, heater 2 adopts set-up mode from the inside to the outside, and its end 202 and head end 201 are guided to scalloped channels 204, after adopting this structure, can arrange bottom connector lug dislocation thermal insulating disc seat 1, avoid from the heat leakage between connector lug and thermal insulating disc seat 1, corresponding holder housing can be made to do less, the structure of product is more miniaturized simultaneously.

Described thermal insulating disc seat 1 is adopt the integrally manufactured shaping dish seat of exotic material, and this exotic material is high temperature resistant composite fibre materials, improves the defect that conventional two-piece heat-generating disc heat leaks from fit clearance, and the useful life of thermal insulating disc seat 2 is also longer.

Be provided with metal shell 3 outside described thermal insulating disc seat 1, this metal shell 3 adopts galvanized sheet to arrange, this metal shell 3 cavity shape and thermal insulating disc seat 1 outer shape suitable, further improve effect of heat insulation, and thermal insulating disc seat 1 is more firm.

As a kind of improvement project: form a vacancy district 205 in the middle part of described heater 2, and be provided with temperature element 5 at the center in vacancy district 205, temperature element 5 is thermocouple, the terminals of this temperature element 5 pass thermal insulating disc seat 1 bottom side and arrange, accurately can measure the temperature at heat-generating disc center like this, the object of accurate temperature controlling can be reached after being combined with control element, also ensure that good heat-proof quality simultaneously.Vacancy district 205 can prevent temperature element 5 from directly contacting with heater 2 and cause damage.

Described thermal insulating disc seat 2 inner chamber 101 outwards expands along openend, and namely inner chamber 101 sidewall 1011 of thermal insulating disc seat 2 is outward-dipping inclined-plane, makes the more multidirectional openend transmission of the heat in thermal insulating disc seat 1, reduces the transmission capacity from sidewall direction, improve thermal insulation effect.

Described heater 2 is " tooth " shape structure, not only can improve the stressed of heater 2 and thermal insulating disc seat 1, and adds the contact area of itself and thermal insulating disc seat 2, makes it more firmly be fixed on thermal insulating disc seat 2

The outer, bottom side of institute's thermal insulating disc seat 2 is provided with the annular installation portion of indent, so that the location of thermal insulating disc seat 1 and holder housing and installation during heat-generating disc.

The position ring of the corresponding annular installation portion of described metal shell 3 is provided with some installing holes 3011, and installing hole 3011 can arrange different spacing, convenient installation in different holder housings.

The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
