An induction cooker with multiple burners

Abstract

The invention discloses an induction cooker with multiple cooking ranges. The induction cooker comprises a power supply input module, a filtering-rectifying module, a driving module, a transformer and the multiple cooking ranges, wherein the power supply input module is used for being connected with an external power supply; the filtering-rectifying module is connected with the power supply input module and is used for filtering and rectifying an input current; the driving module is connected with the filtering-rectifying module and is used for generating a driving signal according to the filtered and rectified input current; a main winding of the transformer is connected with the driving module, and a secondary winding of the transformer is used for generating a driving current according to the driving signal input in the main winding; the cooking ranges are connected in parallel with one another and are connected with the secondary winding of the transformer in parallel. By utilizing the induction cooker with the multiple cooking ranges, provided by the embodiment, the equipment cost of a kitchen can be lowered, the wasting of large amounts of resources is avoided, the equipment failure rate is reduced, and the maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of electromagnetic heating, in particular to an electromagnetic cooker with multiple cooking heads. Background technique [0002] Induction cookers in the industry now use a control circuit to complete the heating work. Among them, the control circuit is from rectification to frequency conversion, control and protection, and then outputs a high-frequency alternating current to the load (wire reel), and the wire reel generates a high-variable magnetic field to act on the bottom of the pot to heat the bottom of the pot. [0003] When multiple induction cookers are required to work at the same time, multiple induction cookers also adopt a one-to-one power supply mode during use, that is, each induction cooker equipment needs to be equipped with its own independent power board, and the place where the induction cooker equipment needs to be used is equipped with more Multiple power input devices. In this way, n...

Problems solved by technology

In this way, not only the cost of each kitchen is higher, but also too many power input devices will cause waste of resources

[0004] Therefore, the shortcoming that prior art exists is, when a kitchen adopts a plurality of induction cooker equipments to work, needs a plurality of power supply input equipments, and its cost increases greatly, and also increases equipment failure rate accordingly

In addition, in the prior art, the inductance in the resonant circuit composed of the wire reel and the pot, when the pot changes, the inductance of the resonant circuit will change, resulting in circuit instability due to the distance from the pot to the wire reel and the change in material , which increases maintenance costs
