Electromagnetic heating cooking system and power regulation device thereof

Abstract

The invention discloses an electromagnetic heating cooking system and a power regulation device of the electromagnetic heating cooking system. The power regulation device comprises a rotating part, W magnets, a fixing part, M hall elements and a control part. The W magnets are arranged on the rotating part and driven by the rotating part to rotate in the circumferential direction. The fixing part and the rotating part are arranged in a layered mode. The M hall elements are arranged on the fixing part. When the M hall elements face the M magnets in the W magnets, induction signals are generated by the M hall elements to form a set of induction information, when the W magnets rotate, W sets of induction information continuously generated by the M hall elements are different to one another, M is an integer which is larger than 1 and smaller than W, and W is a positive integer. The control part is connected with the M hall elements, judges the rotation direction of the rotating part according to at least two sets of induction information and regulates the power of the electromagnetic heating cooking system according to the rotation direction of the rotating part, and therefore continuous and rapid power regulation can be achieved and cannot be interfered by the external environment, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to a power regulating device for an electromagnetic heating cooking system and an electromagnetic heating cooking system with the device. Background technique [0002] In related electromagnetic heating cooking systems, power adjustment is usually performed by key operation, sliding touch or knob adjustment. However, the disadvantages of the related technologies are: firstly, the button operation method needs to be continuously pressed by hand to realize the continuous adjustment of the power, so that the power cannot be adjusted quickly, and the efficiency is low; The requirements are high, and it is susceptible to external interference. For example, water droplets splashed on the panel will cause false triggering; third, the knob in the knob adjustment method is limited by its service life and is easily damaged, and the knob is connected to the internal circuit board.
