Description

The present invention relates to a heating pad, and more particularly to a heating pad for stably placing and heating a container in an electromagnetic furnace.

In general households, an electromagnetic furnace for heating food is usually prepared, and the food is accommodated in a pot container, for example, and the container is made of a magnetically conductive metal material such as cast iron, iron, or steel. When the container is placed in the electromagnetic furnace, it is detected by a detection device inside the electromagnetic furnace, the coil inside the electromagnetic furnace is conducted, and the food in the container is heated by the thermal effect that generates eddy currents at the bottom of the container.

However, since the container placed on the flat furnace surface of the electromagnetic furnace is slippery, the user must be careful that the container slides down. If hot water is contained in the container, there is a risk of burns if the container slips off the electromagnetic furnace or slides down.

Therefore, there is a need for a heating pad for the container to be stably placed and heated on the furnace surface of an electromagnetic furnace, for example.

Then, this invention is applied to an electromagnetic furnace, and it aims at providing the heating pad which can be adsorb | sucked to the furnace surface of an electromagnetic furnace and a container can be set | placed. With this heating pad, the container is stably placed and heated in the electromagnetic furnace, and can be easily removed from the electromagnetic furnace.

The heating pad according to the present invention includes a pad main body and a metal plate accommodated in the pad main body, the bottom of the pad main body is adsorbed on the furnace surface of the electromagnetic furnace, and a container is placed on the top of the pad main body. . After the container and the heating pad are placed on the furnace surface of the electromagnetic furnace and the electromagnetic furnace is turned on, the coil of the electromagnetic furnace heats the metal plate, thereby heating the food in the container.

According to the heating pad of the present invention, the container is stably placed and heated in the electromagnetic furnace, and can be easily removed from the electromagnetic furnace.

Fig. 5 shows a schematic view of the container of Fig. 4 being removed from the heating pad. The schematic diagram of the 2nd Example of the valve | bulb which concerns on this invention is shown. Sectional drawing of the heating pad of 2nd Example which concerns on this invention is shown. Sectional drawing of the heating pad of the 3rd Example concerning this invention is shown.

1 to 5 show a heating pad 10 according to a first embodiment of the present invention. The heating pad 10 is applied, for example, in which a pan container 12 is placed and placed, for example, on a support of an electromagnetic furnace 14. The heating pad 10 allows the container 12 to be stably placed and heated in the electromagnetic furnace 14.

The heating pad 10 includes a pad body 16 and at least one metal plate 18. The pad body 16 is made of an elastically deformable material such as silica gel. The pad main body 16 includes a bottom portion 20 and a top portion 22 that face each other, and a peripheral wall 24 connected between the bottom portion 20 and the top portion 22, and a storage chamber 26 is defined between the bottom portion 20, the top portion 22, and the peripheral wall 24. Is done. The periphery 28 of the bottom 20 of the pad main body 16 protrudes from the peripheral wall 24 in the radial direction and is formed in an arc shape downward, and the bottom 20 of the pad main body 16 has a sucker action due to this. Accordingly, the lower surface 29 of the bottom 20 of the pad body 16 can be adsorbed on the furnace surface of the electromagnetic furnace 14. Further, the periphery 30 of the top portion 22 of the pad main body 16 protrudes to the peripheral wall 24 and is bent upward in an arc shape, and the top portion 22 of the pad main body 16 also has a sucker action due to this. Therefore, the container 12 can be left unattended and positioned. In this embodiment, a through hole 32 is provided in the center of the bottom 20 and top 22 of the pad body 16, a handle 34 extending outward from the peripheral wall 24 of the pad body 16 is provided, and the handle 34 and the pad body 16 are provided. The periphery 30 of the top portion 22 and the periphery 28 of the bottom portion 20 are connected by ribs 36. When the handle 34 is twisted, the periphery 20 and 30 of the bottom 20 and the top 22 of the pad body 16 are interlocked and moved upward. On the other hand, when the force on the handle 34 is released, the periphery 28 and 30 of the bottom 20 and the top 22 of the pad main body 16 are elastically returned to their original positions.

The metal plate 18 is made of a metal material capable of magnetic conduction, such as iron, steel, or cast iron. The metal plate 18 is housed in the housing chamber 26 of the pad body 16, the bottom surface 38 contacts the bottom 20 of the pad body 16, and the top surface 40 contacts the top 22 of the pad body 16. The metal plate 18 is provided with a plurality of through holes 41 for heat dissipation.

When the heating pad 10 is used, the bottom 20 of the pad body 16 is placed on the furnace surface of the electromagnetic furnace 14, the pad body 16 is pushed down, and the lower surface 29 of the pad body 16 is brought into contact with the furnace surface of the electromagnetic furnace 14. The heating pad 10 can be adsorbed and fixed to the furnace surface of the electromagnetic furnace 14. Furthermore, by placing the container 12 on the top 22 of the pad body 16, the container 12 can be adsorbed and positioned on the top 22 of the pad body 16. Therefore, the container 12 can be stably placed in the electromagnetic furnace 14. After the power source of the electromagnetic furnace 14 is turned on, the metal plate 18 of the heating pad 10 is detected by a detection device inside the electromagnetic furnace 14 and is heated by the conduction of the coil inside the electromagnetic furnace 14. The heated metal plate 18 conducts heat to the container 12, whereby the food in the container 12 is heated. On the other hand, when removing the container 12 of FIG. 4 from the electromagnetic furnace 14, the handle 34 (see the arrow 42 in FIG. 4) is twisted to move the periphery 28, 30 of the pad body 16, thereby increasing the adsorption force of the pad body 16. Can be removed. Therefore, the pad body 16 and / or the container 12 can be easily removed from the electromagnetic furnace 14.
