BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pot vibrating device that is attached to a pot heated by an electromagnetic induction cooker.

0002

BACKGROUND OF THE INVENTION The pots used in conventional electromagnetic induction cooking devices are simply vessels made of materials that can be heated by electromagnetic induction (iron, stainless steel, etc.).

0003

[Problems to be Solved by the Invention] However, with the above-mentioned conventional configuration, although it is possible to improve thermal efficiency by heating the pot itself, which is a feature of the electromagnetic induction heating cooker, food may stick to the pot during simmering. When the heat applied to the pot is the same, the speed at which food is simmered is the same as when heated with other cookers (such as gas).

The present invention solves the above-mentioned conventional problems, and the first object is to provide a small-sized electromagnetic induction heating cooker that can prevent food from sticking during simmering and improve the simmering speed of the food. An object of the present invention is to provide a pot shaking device.

[0005] The second purpose is to improve the sticking of food during simmering and the simmering speed of food even when there is a slight deviation between the driving frequency of the electromagnetic induction cooking device and the natural frequency of the pot. It is an object of the present invention to provide a pot vibrating device capable of

[0006]

[Means for Solving the Problems] In order to achieve the above-mentioned first object, the first technical solution of the present invention is to fix the mass body to the mounting part via the elastic body, and to attach the elastic body and the mass body to the mounting part in advance. The natural frequency calculated by the body is set to a value that approximately matches the heating frequency of the electromagnetic induction cooking device, and the mounting portion is fixed to the pot for use.

[0007] In order to achieve the second object, the second technical solution of the present invention is to fix the mass body to the mounting part via the elastic body and the damping body, and to attach the elastic body and the damping body in advance. The natural frequency calculated by the and the mass body is set to a value that approximately matches the heating frequency of the electromagnetic induction cooking device, and the mounting portion is fixed to the pot for use.

[0008]

[Operation] The present invention has the above-mentioned configuration, and the first technical solution allows the heating frequency of the electromagnetic induction cooking device to be adjusted to the natural frequency of the pot vibrating device consisting of an elastic body and a mass body attached to the pot. are the same, so the minute vibrations that occur when heating the pot cause the pot vibrator to resonate,
Increase the vibration of the pot. This vibration improves the movement of the broth in the pot, prevents food from sticking to the inner surface of the pot, and improves heat exchange between the inner surface of the pot and the broth, as well as between the broth and the food. Boiling speed can be improved. Furthermore, since the damping body is not interposed in the pot vibrating device, the vibration level during resonance is high, and a large excitation force can be obtained even with a small pot vibrating device.

[0009] With the second technical solution, the heating frequency of the electromagnetic induction cooking device matches the natural frequency of the pot vibrating device, which is made up of an elastic body, a damping body, and a mass body and is attached to the pot. Therefore, the minute vibrations generated when heating the pot cause the pot vibration device to resonate and increase the vibration of the pot, which causes food to stick to the inner surface of the pot, similar to the first technical solution. This can improve the simmering speed. Further, the resonance characteristics become less sensitive due to the damping body, and the same level of excitation force can be obtained even if the heating frequency of the electromagnetic induction cooking device and the natural frequency of the pot excitation device are slightly different from each other.

In the figure, reference numeral 1 denotes a pot, which has a substantially U-shaped mounting portion 2 on the side of the pot 1. The pot 1 is fitted between the U-shaped portions, and the pot 1 is tightened by tightening screws 3. It is fixed at 4 is an elastic body made of a leaf spring, one end of which is fixed to the mounting part 2, a mass body 5 is attached to the other end, and a cover 6 is fitted into the mounting part 2 so as to cover the elastic body 4. There is. The food 7 to be cooked is placed in the pot 1 along with the broth 8, and placed on an electromagnetic induction cooking device 9 which is provided with a heating coil 10 inside to heat the pot 1.

The operation of the pot vibrating device constructed as above will be explained below. When the electromagnetic induction cooking device 9 is turned on and a high-frequency current is passed through the heating coil 10, the pot 1 is heated by electromagnetic induction.
Since the natural frequencies of the vibration system made up of the above are almost the same, the elastic body 4 and mass body 5 of the pot vibrator cause resonance due to minute vibrations generated when the pot 1 is heated, and the vibrations of the pot 1 are caused to resonate. increase. This vibration gives fluidity to the broth 8 in the pot 1, and this action causes the cooking liquid 7 to stick to the inner surface of the pot 1 during simmering.
In addition, the heat exchange between the inner surface of the pot 1 and the broth 8 and the heat exchange between the broth 8 and the food 7 can be improved, and the simmering speed can be improved. Further, as shown in FIG. 2, since the damping body is not interposed in the vibration system, the vibration level during resonance is high, and even a small pot vibration device can obtain a large vibration force. Furthermore, the pot vibrating device is constructed so that it can be removed using screws 3 when it is not needed.
