Abstract
The utility model relates to an automatic purple pottery electric cooker, belonging to the household electrical appliance. The general purple pottery electric cooker comprises a purple pottery cooker liner, a cooker lid, a metal inner liner, a mica heat insulating plate, heat preservation cotton, a heat-generating pipe, an outer shell, a temperature limiter and a power plug. The utility model is characterized in that an annular metal lid is arranged between the bottom of the purple pottery cooker liner and the heat-generating pipe, and the center of the metal inner liner is provided with a heat insulating sleeve and a floating sleeve. The utility model mainly transfers heat through the modes of radiation and convection, and overcomes the defects that the heat transferring of the traditional purple pottery electric cooker is not even, the purple pottery cooker liner is easy to rupture, and the thermal efficiency is low. The utility model has the advantages of simple structure, even heat transferring and long service life, and is suitable for being used in the family and the dining hall.
Description
The utility model belongs to household electrical appliance.
The heating element structure that existing boccaro electric cooker great majority all adopt heating board and heating tape to form, because boccaro pot courage formed precision is low, the appearance and size deviation is big, therefore above-mentioned heating element structure is very low to the fit of boccaro pot courage, simultaneously, this heater mainly transmits heat with conduction and convection type, thereby intensification is slow, the thermal efficiency is low.In addition, above-mentioned heater adopts mica frame to form around resistance wire, and moistureproof shockproof properties is relatively poor, and service life is shorter.
The purpose of this utility model provides that a kind of shockproof properties simple in structure, moistureproof is good, long service life, energy-efficient automatic boccaro electric cooker.
The utility model is achieved in that it comprises boccaro pot courage, pot cover, metal liner courage, mica thermal insulation board, heat-preservation cotton, heat-generating pipe, shell, temperature limiter and attaching plug, in addition, the endless metal lid is arranged between boccaro pot courage bottom and heat-generating pipe, and heat-generating pipe is fixed between metal liner courage and the endless metal lid; In metal liner courage central authorities collet and floating bushing that can lifting are arranged, collet is fixed on the metal liner courage, floating bushing is by unsteady housing, compression spring and slide bolt are formed, on the metal liner courage of upright position below the housing that floats, several through holes are arranged, slide bolt passes the endoporus of compression spring, one of slide bolt connects the housing that floats, and the through hole at metal liner courage place is passed out in the other end, floating bushing is contained in collet central authorities, temperature limiter is contained in the central authorities of floating bushing, temperature limiter is positioned at the central authorities of boccaro pot courage bottom, floating bushing all contacts with boccaro pot courage bottom with temperature limiter, in metal liner courage bottom the mica thermal insulation board is arranged, the excircle of metal liner courage has mica thermal insulation board and heat-preservation cotton.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the half sectional view of the utility model embodiment.
Fig. 2 is the schematic diagram of floating bushing among the utility model embodiment.
Fig. 3 is the circuit theory diagrams of the utility model embodiment.
Fig. 4 is the schematic diagram of heat-generating pipe among the utility model embodiment.
With reference to Fig. 1, Fig. 2, boccaro pot courage 1 is contained in the metal liner courage 2, and mica thermal insulation board 4 and heat-preservation cotton 5 are wrapped on the metal liner courage 2, and it is too high that mica thermal insulation board 4 and heat-preservation cotton 5 not only can be incubated but also can prevent that shell 3 from heating up.The openend of the heat-generating pipe 7 overlapping (see figure 4) that staggers has endless metal lid 6 between boccaro pot courage 1 bottom and the heat-generating pipe 7, heat-generating pipe 7 is fixed between metal liner courage 2 and the endless metal lid 6 by intermediate plate 9.In metal liner courage 2 central authorities collet 10 and floating bushing 17 that can lifting are arranged, collet 10 is fixed on the metal liner courage 2, floating bushing 17 is by unsteady housing 11, compression spring 12 and slide bolt 13 are formed, on the metal liner courage of upright position below the housing 11 that floats, 3 through holes 14 are arranged, one of slide bolt 13 connects the housing 11 that floats, and the through hole 14 at metal liner courage 2 places is passed out in the other end, floating bushing 17 is contained in the central authorities of collet 10, temperature limiter 15 is contained in the central authorities of floating bushing 17, temperature limiter 15 is positioned at the central authorities of boccaro pot courage 1 bottom, floating bushing 17 all contacts with the bottom of boccaro pot courage 1 with limit temperature cover 15, mica thermal insulation board 4 is arranged as thermal insulation layer in metal liner courage 2 bottoms, attaching plug 8 stretches out from the lower end of shell 3, and pot cover 16 covers on boccaro pot courage 1.
The utility model characteristics are to add an endless metal lid between purple casserole courage bottom and heat-generating pipe, add collet and floating bushing that can lifting in metal liner courage central authorities, floating bushing all contacts with purple casserole courage bottom with temperature limiter, the purple casserole courage is heated evenly, this structure is mainly conducted heat in the mode of radiation and convection current, has overcome the shortcoming that traditional puple pottery electric cooker heat transfer is inhomogeneous, the purple casserole courage breaks easily and the thermal efficiency is low. The utility model is simple in structure, heat transfer is even, long service life, moistureproof shockproof properties are good, and it suits to use in family, dining room.
