Abstract
A kitchen appliance is disclosed. The kitchen appliance comprises: a user interface control unit for interacting with a user; a plurality of driver units configured to control power supply to a plurality of coils; and the plurality of coils configured to heat one or more cookers based on electromagnetic induction effect, wherein each driver unit is configured to generate a control signal for a corresponding coil of the plurality of coils, and the control signal is used for controlling the power supply to the corresponding coil by controlling turn-on or turn-off of an insulated gate bipolar transistor (IGBT) in a single-pipe module.
Claims15
A kitchen appliance, comprising:
- a user interface control unit for interacting with a user;
- a plurality of driver units configured to control power supply to a plurality of coils;
- and
- the plurality of coils configured to heat one or more cookers based on electromagnetic induction effect,
- wherein each of the plurality of driver units is configured to generate a control signal for a corresponding coil of the plurality of coils,
- wherein each of the plurality of driver units comprises at least two driver microcontrollers, wherein each driver microcontroller of said at least two driver microcontrollers is configured to drive one of the plurality of coils with an alternating current (AC) power being converted from a direct current (DC) power, and
- the control signal of each of the plurality of driver units is used for controlling turn-on or turn-off of an insulated gate bipolar transistor (IGBT) in a single-pipe module in order to control the power supply to the corresponding coil.
A kitchen appliance, comprising:
- a plurality of heating units, each heating unit comprising:
- an induction coil;
- and
- a driver microcontroller configured to drive the induction coil with an alternating current (AC) power based on a control command, the AC power being converted from a direct current (DC) power;
- a plurality of driver circuit boards, each of the driver circuit boards comprising at least two of the driver microcontrollers;
- a user interface circuit board configured to receive an input from a user and to generate and communicate the control command to a corresponding driver circuit board based on the received input;
- and
- a power circuit board configured to receive the DC power and to supply the DC power to the driver circuit boards and to the user interface circuit board,
- wherein communication between the user interface circuit board and the driver circuit boards is performed in accordance with an inter-integrated circuit (IIC) protocol, the user interface circuit board being a master device and the driver circuit boards being slave devices, and
- wherein at least a portion of the induction coils operate simultaneously while being controlled independently.
