A hob that uses magnetic induction rather than thermal conduction, convection or radiation. This means there is no naked flame to burn your hands.
The invention utilizes vibration detection and a micro-electromechanical system in order to securely determine when a substance has reached a boiling state on one of the different heating zones. Energy supplied to the respective heating zone that supports the boiling substance can then be controlled to simmer it.
Ceramic glass cooktop
The cooktop is a sleek and attractive choice for the modern kitchen. Its flat surface and easy-to-clean ceramic coating makes it a great alternative to the clunky coil burners of traditional electric cooktops. Ceramic cooktops are also durable and resistant to scratching and chipping. However, they require regular maintenance and cleaning to keep them looking like new.
The smooth surface of an induction hob is heat permeable and directly transmits the power to the pan. A pot is placed on the ceramic glass surface and the electromagnets underneath it create an electromagnetic field to generate heat. The electromagnetic field only produces heat in the pot if it is made of or contains ferrous metal (iron, cast iron, some stainless steels). The cooktop will not work with copper, aluminum, or other non-ferrous metals.
To use the dual zone elements, turn the control knob to the ‘On’ position and then adjust the element size by turning the dial clockwise from 6 to 1. An indicator light glows red when an element is on. To turn off the cooktop, press and hold the ‘Element on’ button for four seconds. Then, press and turn the dial to the ‘Off’ position. The control knobs are dishwasher-safe. The cooktop can also be cleaned with water and a little dish soap.
Heat transfer technology
Heat transfer technology is used in a wide range of applications including food processing, oil and gas refinement, and even aerospace engineering. It is also an important part of developing sustainable energy technologies and reducing environmental pollution. Research on advanced heat transfer knowledge and theory is crucial to solving problems in traditional and emerging industries.
Induction hobs use magnetic induction to directly heat independent cooking zones, so the cooktop surface remains cool. Only the area of the pan in contact with the copper coils gets hot. This makes induction more energy efficient than electric or gas cookers. It is also a safer option as it won’t heat up a pan or its handle, and it won’t set things like cloths or towels (or arm hair) on fire.
Induction hobs can be used with a wide range of pans, including enameled cast iron and stainless steel, as long as they are magnetic. Some aluminium and some glass cookware won’t work, but this can usually be overcome with a special base or the use of a pan detection function found on some models. You’ll hear a humming or ticking sound from the hob during cooking, which is normal. The noise will increase at higher heat settings. It may also make a clicking sound when switching between power levels.
Boil sensor hob
The Boil sensor hob automatically reduces to a controlled simmer when the water reaches a boil. It saves energy and prevents overboiling and spillages. The function is activated by pressing the automatic button and can be deactivated at any time by touching the button again or lifting the pot.
The computer program product comprises a storage card with instructions for controlling the induction hob by performing the boiling detection and the calculation of energy to be required for simmering. The computer program product can be read by a controller in the induction hob. The computer program product can also cause the induction hob to perform an automated function started e.g. by a button shown in FIG. 1.
The boiling sensor hob has a micro-electromechanical system, also known as a MEMS (micro-electromechanical system), as a vibration sensor. bep dien tu munchen It combines this with respective temperature sensors to detect vibrations of heated substances on the heating zones and identify them as boiling. The automated function then starts to indicate a boiling state to a user and after a suitable amount of time reduces the power supplied to the heating zone to maintain the substance in a simmering state. This can be done without any manual intervention by a user and with minimal effort, which results in an easy to use, safe and energy efficient kitchen.
