Electromagnetic electric-pressure cooker

Abstract

The application of the invention relates to the technical field of electric-pressure cookers, in particular to an electromagnetic electric-pressure cooker. The electromagnetic electric-pressure cooker comprises a base, a bottom cap, an outer cover and a liner, wherein a power supply box is arranged in the base, an electromagnetic heating plate is arranged betweenthe outer cover and the liner, a fan and a heat sink are arranged in the power supply box, a funnel-shaped air guiding opening is arranged in the power supply box, the fan is arranged above the air guiding opening, and the heat sink is tightly leaned against the fan; the electromagnetic heating plate comprises a coil plate, a magnetism-isolating plate and a sensor assembly, an annular large winding area formed by a plurality of concentrically arranged coil slots is formed in an inner cavity of the coil plate and is divided into a plurality of small winding areas and ventilating slots, the small winding areas and the ventilating slots are arranged alternatively, and the slot bottoms of the ventilating slots are lower than the slot bottoms of the coil slots. Compared with the prior art, the electromagnetic electric-pressure cooker disclosed by the application of the invention has the advantages that the heat dissipation structure of the whole electric-pressure cooker is optimized, the whole heat dissipation performance is reinforced, the structure of the electromagnetic heating plate is simplified, and the manufacturing and assembling processes are simpler.

Description

technical field [0001] The present application relates to the technical field of electric pressure cooker, in particular to an electromagnetic electric pressure cooker. Background technique [0002] With the development of electromagnetic heating technology, electromagnetic heating has been applied to various heating appliances, from the earliest application of induction cooker, to the later electromagnetic heating rice cooker, and the "Korean" structure electromagnetic heating electric pressure cooker in recent years. Applied to electromagnetic heating technology. At present, the "匚" structure electric pressure cooker has been vigorously promoted in China, and the international standard also takes the "匚" structure as the standard, so the "匚" structure electric pressure cooker has become the mainstream of electric pressure cooker development. However, the electric pressure cooker with the "匚" structure controls the pressure through the elastic deformation of the metal cove...

Problems solved by technology

[0003] In the prior art, the electromagnetic electric pressure cooker mainly includes a base, a bottom cover, an outer cover and an inner container arranged on the base, a power supply box and a pressure switch assembly are arranged in the base, and an electromagnetic heating plate is arranged between the outer cover and the inner container. The disadvantages are: 1) The heat dissipation structure design of the electromagnetic heating plate and the entire electric pressure cooker is unreasonable, especially there is no matching heat dissipation structure between the power box and the outer cover, base, bottom cover and electromagnetic heating plate, and the “匚” type structure The entire electromagnetic heating plate of the electric pressure cooker is placed between the inner pot and the outer pot, and the space itself is small, which leads to poor cooling effect of the coil and affects the service life of the electric pressure cooker; 2) The structure of the electromagnetic heating plate is complex, including the pressure plate and Coil reel, the coil is wound on the coil reel, and then the magnetic strip is fixed on the coil reel to form a whole coil reel, and then the wire reel is fixed on a pressure bearing plate for bearing pressu
