Description
Technical field
The present invention relates to electric pressure cooking saucepan technical field, be specifically related to a kind of electric pressure cooking saucepan of Electromagnetic Heating.
Background technology
Along with the development of family's power technology, the household appliances of energy saving economy are the common demands of household electric appliances and society, and the electromagnetic heating technique with power saving advantages is applied to the electrical equipment of various heating class gradually.The principle of electromagnetic heating technique is by producing alternating magnetic field, cutting ferrous metal container produces the electric current (i.e. eddy current) of alternation, eddy current makes the iron atom high speed random motion of container bottom, atom collides with each other, rub and produce heat energy, thus reach the effect of heating objects, therefore, adopt the electric pressure cooking saucepan of electromagnetic heating technique to become the emerging field of industry development gradually, and there is vast potential for future development.
At present, " Korea Spro " formula that electric pressure cooking saucepan mainly contains and " Contraband " formula two kinds of structures, wherein " Korea Spro " formula structure is not that thus its outer pot can not be stressed based on elastic deformation, therefore can by the nonmetallic materials of high strength as plastic cement replaces the metal outer pot of " Contraband " formula structure, " Korea Spro " formula electric pressure cooking saucepan is the electric pressure cooking saucepan applying electromagnetic heating technique the earliest thus, and " Contraband " formula structure is to realize pressure control with the elastic deformation of outer pot, compare and greatly will be better than " Korea Spro " formula structure on performance safety, but simultaneously, because " Contraband " formula structure need carry out controlled pressure with elastic deformation, be subject to many limitations so electromagnetic heating technique to be applied to " Contraband " formula structure, such as: thus the outer pot of " Contraband " formula structure must select because bearing elastic deformation the stainless steel or cold-rolled steel sheet material that iron content is higher, in addition magnetic field energy penetrates any object, when electromagnetic heating technique is directly applied in " Contraband " formula structure, namely magnetic field penetrate outer pot, while internal pot carries out heating, outer pot is also heated simultaneously, this basic reason making electromagnetic technique delay at present to be applied on the electric pressure cooking saucepan of " Contraband " formula structure.
Chinese patent CN 202312832U discloses a kind of electromagnetic heating pressure cooker, although the principle heated by electromagnetic coil disk in its technical scheme is heated to inner bag, but its defect is, 1) elastic construction of this pressure cooker is modular construction: be made up of inner bag, nonmetal supporting disk and outer courage, between supporting disk and outer courage, electromagnetic coil disk is set, elastic construction after assembling takies larger inner space, considerably increases the height bottom pressure cooker; 2) because electromagnetic coil disk is positioned over centre position, thus make feet away from the center of circle of the bottom of outer courage, cause the outside of outer courage to concentrate stressed and middle stressed weakness, and supporting disk adopts nonmetallic materials, its pressure-bearing and elastic deformation ability is difficult to realize accurately, stably pressure control; 3) this pressure cooker is not every magnetic device, although be provided with through hole bottom outer courage, but the electromagnetic action that coil produces is to still can the edge heating of external courage while inner bag heating, thus cause whole pressure cooker to generate heat, have a strong impact on the security performance of product, because of but actual production and the use of electric pressure cooking saucepan cannot be applied to.
Chinese patent CN202537143U discloses a kind of prevention electromagnetic pressure cooker, although add electromagnetic shielding plate in its technical scheme, magnetic field exposure can be prevented, but still there is following defect: 1) elastic construction is modular construction: be made up of inner bag, supporting seat, pressure plare, coil panel assembly, planar spring, stay-warm case etc., elastic construction after assembling takies larger inner space, and build-up of pressure pot whole height is much higher than common voltage power pot; 2) heat accumulation that produces due to galvanomagnetic-effect of coil panel assembly itself is in inside, and due to design not considering radiator structure, the heat causing electromagnetism to produce cannot promptly distribute, and its heat dispersion is poor, thus affects the service life of electric pressure cooking saucepan.
Therefore, how to optimize the structure of " Contraband " formula electric pressure cooking saucepan further, realize accurate temperature controlling pressure control, long service life and good heat dispersion, the electric pressure cooking saucepan that is applied to that can be real to electromagnetic heating technique is had very important meaning.
