Technical field
The utility model relates to the kitchen kitchenware, relates in particular to a kind of electric cooker attemperator and electric cooker.
Background technology
At present, the housing of known electric cooker and lid are processed by metal and plastics, and heat-insulating property is very poor; Thereby heat energy in pot is dispersed in the air easily in it; Pot will be incubated in it, needs to lean on heating plate constantly to heat and could keep the temperature in the interior pot, so not only consumed power; And its heat insulation effect is not ideal enough, and service efficiency is poor.
The utility model content
The purpose of the utility model is to provide a kind of electric cooker attemperator and electric cooker, not only can be incubated, and saves energy.
The purpose of the utility model realizes through following technical scheme.
A kind of electric cooker attemperator is applied to electric cooker, and this device comprises the PTC heater, and the PTC wiring that is electrically connected with the PTC heater connects stroma, and fixed structure; Said PTC heater is fixed on the electric cooker through said fixed structure.
Preferably, said device comprises that also NTC temperature controller and the NTC wiring that is electrically connected with this NTC temperature controller connect stroma, and said NTC temperature controller is fixed on the electric cooker through said fixed structure.
Preferably, said fixed structure comprises aluminium foil and double faced adhesive tape, and said aluminium foil is pasted on the one side of double faced adhesive tape, and the another side of this double faced adhesive tape is pasted on the said electric cooker, and said PTC heater and NTC temperature controller all are fixed between aluminium foil and the double faced adhesive tape.
Preferably, the another side of said double faced adhesive tape is pasted on the loam cake or chassis of electric cooker.
Preferably, two aluminium flakes that said fixed structure is fixed on the said electric cooker after by closed assembly are formed, and said PTC heater and NTC temperature controller all are held between these two aluminium flakes.
Preferably, be fixed on the loam cake or chassis of said electric cooker behind said two aluminium flake closed assemblies.
Preferably, said PTC heater comprises PTC heater element, electrode slice, lead and is sheathed on the outside insulating paper cover of PTC heater element.
Preferably, said NTC temperature controller comprises NTC element, the lead that is connected with the NTC element and the insulating sleeve that is sheathed on the NTC element-external.
A kind of electric cooker comprises main body, loam cake and chassis, also comprises aforesaid electric cooker attemperator, and this electric cooker attemperator is installed on loam cake or the chassis.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model; The PTC heater fixes on electric cooker through an aluminium foil and double faced adhesive tape/two aluminium flake; After the energising heat is being passed on the loam cake or chassis of electric cooker slowing down the heat loss effect and can realize good heat insulation effect in conjunction with heat conduction aluminium foil/aluminium flake; In addition, the utility model also adopts the NTC temperature controller, utilizes the conductive force of heat conduction aluminium foil/aluminium flake can carry out temperature-sensitive exactly, thereby has realized the temperature control effect simultaneously.
Description of drawings
Fig. 1 is the structural representation of electric cooker attemperator among the utility model embodiment;
Fig. 2 is the assembly method sketch map of electric cooker attemperator among the utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
In the utility model, the electric cooker attemperator comprises that mainly PTC heater, the PTC wiring that is electrically connected with the PTC heater connect stroma, NTC temperature controller, the NTC wiring that is electrically connected with the NTC temperature controller connects stroma, fixed structure; When mounted, PTC heater and NTC temperature controller are fixed on the electric cooker through fixed structure, play heating and temperature control effect respectively, realize good heat insulation effect with cooperation mode.Wherein, the concrete structure of fixed structure does not limit, can be varied; Its basic role is the position of fixing PTC heater and NTC temperature controller, and in order to promote heat insulation effect, can select Heat Conduction Material for use; Like aluminium foil or aluminium flake etc.; Cooperate PTC heater and the effect of NTC temperature controller, thereby, finally reach the purpose of lifting heat insulation effect to slow down thermal loss, to make the degree of accuracy that heat on the electric cooker more evenly improves NTC temperature controller temperature-sensitive.To be that example further specifies the utility model with the fixed form that adopts aluminium foil+double faced adhesive tape only below, the basic principle when adopting other fixed structures be identical, repeats no more here.
See also shown in Figure 1ly, the electric cooker attemperator comprises following part in the present embodiment: the NTC wiring that heat conduction aluminium foil 1, double faced adhesive tape 2, PTC heater 3, NTC temperature controller 4, the PTC wiring that is electrically connected with PTC heater 3 connect stroma 5, be electrically connected with NTC temperature controller 4 connects stroma 6.
NTC temperature controller 4 is by NTC element 41, the Teflon lead 42 that is connected with NTC element 41 and be sheathed on the outside heat-proof silica gel pipes 43 of NTC element 41 and form, and the NTC wiring that Teflon lead 42 and NTC wiring connect stroma 6 connects sub 61 and is connected.
As shown in Figure 2, heat conduction aluminium foil 1 is pasted on the one side of double faced adhesive tape 2, and PTC heater 3 and NTC temperature controller 4 are fixed between heat conduction aluminium foil 1 and the double faced adhesive tape 2, and the another side of double faced adhesive tape 2 is pasted on the loam cake or chassis of electric cooker.
In application process, with PTC heater 3 and 4 energisings of NTC temperature controller; After PTC heater 3 heating, transfer heat on electric cooker loam cake or the chassis and reach insulation effect, because heat conduction aluminium foil 1 can reduce heat loss, promoted heat insulation effect simultaneously; Meanwhile, because the heat transfer process of heat conduction aluminium foil 1 is individual, NTC temperature controller 4 can induce current temperature exactly; Thereby further control the fever time of PTC heater; Reach preset holding temperature,, make product hommization more for user's use provides convenience.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
