AI Technical Summary
Existing induction hobs suffer from energy inefficiency and heat-related damage to the base due to direct heat transfer, and pots can move during cooking.
A heat-insulated pot design with a silicone layer between the pot and the induction hob, minimizing energy loss and preventing base damage by using a heat-insulated base with a non-slip effect.
Enhances energy efficiency and prevents base damage while maintaining pot stability during cooking.

Abstract
Description
[0001] Heating water requires a defined amount of energy (4.18 joules per gram and degree Celsius). When water is heated in a pot on a stovetop, the pot, the stovetop, and the surrounding air also absorb energy. The aim of the invention is to minimize the energy not used for heating the water.
[0002] Induction hobs offer significantly better energy transfer than gas or electric hobs, especially during heating, because with an induction hob the electrical energy is transferred directly to the pot via induction.
[0003] To minimize energy loss to the environment, heat-insulated or double-walled pots are commonly used. For example, a pot can be encased in a temperature-resistant and flexible plastic such as silicone around an insulating layer such as fiberglass.
[0004] According to the invention, the bottom of the pot is placed, pressed or glued onto a heat insulation layer or several heat insulation layers that are flush with the edge of the bottom of the pot, for example one (1) or more silicone ring(s) or a silicone disc, for example with a high temperature resistant silicone / metal adhesive.
[0005] The bottom of the pot is positioned slightly further away from the induction hob / induction coil due to the heat insulation layer, e.g., the silicone ring (1), and therefore absorbs slightly less induction current. However, the effect of the glass hob absorbing less heat from the pot due to the "air cushion" between the pot and the glass plate outweighs this.
[0006] If the hot pot is placed on a base, the silicone layer (1) prevents heat-related damage to the base.
[0007] Furthermore, the silicone layer (1) has a non-slip effect. When food is fried in the pan / pot with the heat-insulated base, the pan / pot does not move when a spatula is used.
Claims

[2] Heat-insulated pot for an induction hob with a ring-shaped or circular insulating layer made of a poorly heat-conducting material attached to the bottom of the pot.
