With a container laid on an induction cooker and detected by a detection device of the induction cooker, coils inside the induction cooker will be activated to generate eddy current on the container's lower portion and thermal efficiency for foods heated in the container. However, the container placed on a plane furnace surface of the induction cooker is easily slid, deserving to be noted by one consumer for any possibility of the container turned over.
- It is possible to result in an accident of one user scalded by the container which is filled with hot soup and dropped or turned over from the induction cooker.
- Therefore, there is one demand to provide a heating pad used in stabilizing a container placed on and heated by a cooking utensil such as an induction cooker without any sliding.
- Thus, an objective of the present invention is to provide a heating pad applicable to an induction cooker to improve the aforementioned problems. The heating pad of the present invention is adapted to be sucked on an induction cooker and to be placed on by a container. Because of the heating pad, one container can be securely laid on the induction cooker for heating. Furthermore, the heating pad allows the container to be easily removed from the induction cooker.
- To achieve this and other objectives, a heating pad applicable to an induction cooker of the present invention includes a pad body and a metal sheet which is held in the pad body. The pad body includes spaced lower and upper portions, a peripheral wall interconnected between the lower and upper portions, and a cavity defined by the lower and upper portions and the peripheral wall. A circumference rim around the lower portion of the pad body protrudes from the peripheral wall and is cambered downward so that a lower surface of the lower portion of the pad body is adapted to suck on an induction cooker. The upper portion of the pad body is adapted to carry a container. The metal sheet is received in the cavity of the pad body and includes a lower face in contact with the lower portion of the pad body and an upper face in contact with the upper portion of the pad body.
- In a preferred form, a handle is extended outwardly from the peripheral wall of the pad body, and a rib is connected between the handle and the circumference rim of the lower portion of the pad body, so that the circumference rim of the lower portion of the pad body is driven to move upwards when the handle is pulled by one user.
- In a preferred form, a circumference rim around the upper portion of the pad body protrudes from the peripheral wall and is cambered upwards so that the container can suck on the upper portion of the pad body.

Because of the effect of theheating pad 10, thecontainer 12 can be securely placed on theinduction cooker 14 for heating. - The
heating pad 10 of the present invention includes apad body 16 and at least onemetal sheet 18. Thepad body 16 is manufactured with a flexible material such as a silicon rubber. Thepad body 16 includes lower andupper portions peripheral wall 24 interconnected between the lower andupper portions cavity 26 defined by thelower portion 20, theupper portion 22 and theperipheral wall 24. In this embodiment, a circumference rim 28 around thelower portion 20 of thepad body 16 is radially protruded from theperipheral wall 24 and is bended downward to be cambered for thelower portion 20 of thepad body 16 acting as a chuck. As a result, alower surface 29 of thelower portion 20 of thepad body 16 can be sucked on a furnace surface of theinduction cooker 14. Furthermore, a circumference rim 30 around theupper portion 22 of thepad body 16 radially protrudes from theperipheral wall 24 and is bended upward to be cambered for theupper portion 22 of thepad body 16 acting as another chuck to carry and position thecontainer 12. In this embodiment, theheating pad 10 further includes a through-hole 32 formed in a center of each of the lower andupper portions handle 34 extending outwardly from theperipheral wall 24 of thepad body 16, and arib 36 connected between thehandle 34 and each of thecircumference rims upper portions pad body 16. The circumference rims 28 and 30 of the lower andupper portions pad body 16 are driven to move with thehandle 34 pulled by one user but rebounded with the pulling force on thehandle 34 gone. - The
metal sheet 18 is manufactured with a metallic magnetic-conductivity material such as iron, steel, or cast iron. Themetal sheet 18 is received in thecavity 26 of thepad body 16 with alower face 38 of themetal sheet 18 contacting thelower portion 20 of thepad body 16 and with anupper face 40 of themetal sheet 18 contacting theupper portion 22 of thepad body 16.
