As shown in the figure, a heating coil 3 is fixed below a top plate 2 on which a pot to be heated 1 is placed, a control board 4 is located below the heating coil 3, and a heat shield is provided below this control board 4. Board 6
was fixed to prevent a rise in temperature of the floor surface and leakage of magnetic flux from the heating coil 3. Furthermore, the temperature of the heated pot 1 is detected by a single heat-sensitive element 6 located at the center of the heating coil 3 via the top plate 2.

Furthermore, a cooling fan 8 is used to suppress the temperature rise inside the main body 7.
By rotating the , external air was admitted through one suction port 9 and heated air was discharged from the other exhaust port 1o.

Problems to be Solved by the Invention In such a conventional cooker, the heated pot 1 heated by the heating coil 3 is placed on the top surface of the top plate 2 which is made of ceramic and has a smooth surface. When the food put into the heated pot 1 is stirred, the heated pot 1 moves every time it is stirred, and in the worst case, the heated pot 1 falls off the top plate 2 and the cooked food spills. However, there were problems such as burns to the user. Furthermore, a heated pot 1 made of metal or ceramic is placed on a top plate 2.
If the top plate 2 made of ceramic is handled roughly by the user when the top plate 2 is placed on the holder, the top plate 2 made of ceramic may be damaged or the end face may be damaged. In addition, in the case of the heated pot 1 made of earthenware, the bottom surface of the heated pot 1 does not move even when stirring the food put in the pot 1, making cooking easier. Furthermore, the first object is to provide an induction heating cooker in which the top plate 2 will not be damaged even if the user handles it somewhat roughly.

The second object is to provide an induction heating cooker in which the heated pot 1 is securely fixed and both the top plate 2 and the heated pot 1 are not damaged regardless of how the user handles them.

Means for Solving the Problems In order to achieve the above object, the present invention provides a heating coil, a flat top plate covering the upper surface of the heating coil, and a flat top plate placed on the upper surface of the top plate. a convex rib extending downward on the outer periphery of the bottom of the heated pot; a rubber sheet is adhered to the inside and bottom of the convex rib of the heated pot, and the rubber sheet is engaged with the outer circumference of the top plate; In particular, it locks the pot to be heated.

Function: The cooking device of the present invention has the above-mentioned structure, and a rubber sheet is fixed to the portion where the convex rib extending downward on the outer periphery of the bottom of the heated pot engages with the outer periphery of the top plate. When placing the pot to be heated on the ceramic top plate, the end of the top plate engages with a rubber sheet fixed to the convex ribs of the pot to be heated, so the rubber sheet provides cushioning. Even if a shock is applied to the pot to be heated, the end face of the top plate will not be damaged. Furthermore, by engaging the convex ribs with the outer peripheral edge of the top plate, the heated pot can be temporarily fixed, and even if the food placed in the heated pot is stirred during cooking, the heated pot will not stir. without moving every time
It makes cooking easier.

Still, a concave part is provided on a part of the outside of the convex rib that extends downward on the outer periphery of the bottom of the pot to be heated that is placed on the top surface of the top plate.
By covering the entire convex rib with a rubber sheet and engaging one end of the sheet with the recess, the sheet adheres to the heated pot and the sheet does not easily fall off from the heated pot during use. do not have.

Furthermore, since the entire convex rib is covered with a rubber sheet, even if the user accidentally bumps the convex rib against the top plate, the rubber sheet acts as a cushion and prevents damage to the top plate. When the pot to be heated is placed on the ceramic top plate, the end of the top plate engages with the rubber sheet fixed to the convex ribs of the pot to be heated, so the rubber sheet is attached to the cushion and fL shield. Heated example: Even if an impact is applied, the end face of the top plate will not be damaged. Furthermore, by engaging the convex ribs with the outer peripheral edge of the top plate, the heated pot can be temporarily fixed, and even if the food placed in the heated pot is stirred during cooking,
The heated pot does not move every time it is stirred, making cooking easier.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in the figure, heated pot 1 in which food is placed and cooked.
1 is heated by magnetic flux generated from a heating coil 12, and the heating coil 12 is insulated by a ceramic top plate 13 covering the top surface. Then, it passes through the approximate center of the top plate 13, and the top plate 13
A cylindrical heat-sensitive section 16 made of a metal (for example, aluminum) with good thermal conductivity and containing a heat-sensitive element 15 inside is provided on the high-frequency control board 17, and the heating section 16 is heated. The temperature of the heated pot 11 is sensed by contacting the bottom surface of the pot 11.

Further, a convex rib 18 extending downward is provided on the outer periphery of the bottom of the heated pot 11, and a rubber sheet 19 is adhered to the inside of the convex rib 18 and the bottom surface, and the outer periphery 2o of the top plate 13 is
The inner side of the convex rib 18 of the heated pot 11 is provided to engage with the inner side of the convex rib 18 of the heated pot 11 via the rubber sheet 19, and the heated pot 11 is temporarily fixed to the main body 21. A gap portion 22 is formed between the rubber sheet 19 and the rubber sheet 19.

Further, the magnetic flux of the heating coil 12 is controlled by a high-frequency control board 17 located below, and the heat-sensitive element 16 is connected to the high-frequency control board 1T and adjusts the temperature and firepower in conjunction with the adjustment switch 23. . And heated pot 1
1 is heated, the temperature inside the high frequency control board 17 and the main body 21 rises, so by rotating the cooling fan 24, outside air is taken in through the intake port 26 provided in the main body 21.
The inside of the main body 21 is configured to be cooled by exhausting heated air from the exhaust port 26.

To explain the operation in the above configuration, the convex rib 18 provided on the pot to be heated 11 is
By fitting the pot 11 into the main body 21, the pot 11 to be heated is temporarily fixed to the main body 21 via the rubber sheet 19 provided on the inside of the convex rib 18 and the bottom surface. Even if the food put in the cooking pot is stirred, the ceramic top plate 1 having a smooth surface is removed every time the heated pot 11 is stirred.
3.It prevents the top from being moved horizontally inadvertently, making it safe and making cooking easier. Moreover, since the heated pot 11 and the top plate 13 are interposed through the rubber sheet 19, they do not come into direct contact with each other, and the rubber sheet 19 acts as a cushion, so the user violently pushes the heated pot 11 onto the top plate 1.
3, the outer peripheral portion 2o of the ceramic top plate 13 is not damaged, and no impact noise is generated. Furthermore, since a gap 22 is formed between the object to be heated 11 and the top plate 13 by the thickness of the rubber sheet 19, the heat generated in the pot to be heated 11 by the magnetic flux generated from the heating coil 12 is directly transmitted. The temperature of the top plate 13 can be prevented from increasing without being transmitted to the top plate 13, and the inside of the main body 21 in which the heating coil 12, high frequency control board 17, etc., which are sensitive to high temperatures, are provided can be protected from heat. Also,
The heated pot 1 is heated by the magnetic flux generated from the heating coil 12.
Although high-frequency vibrations occur in the heating element 1, the rubber sheet 19 can prevent abnormal noises such as chattering between the heated pot 11 and the top plate 13.

Next, a second embodiment of the present invention will be described with reference to FIG.

Note that the same parts as in the first embodiment are given the same numbers and detailed explanations will be omitted.

As shown in the figure, a recess 31 is provided on the outer circumferential side of the convex rib 30 provided at the bottom of the heated pot 11 to cover the lower surface of the convex rib 30 and the inner circumferential surface of the convex rib 3o and the bottom of the heated pot 11. a rubber sheet provided with an inner peripheral piece 32 that tightly contacts a part of the convex rib 3o, and an engaging piece 33 that closely contacts the outer peripheral surface of the convex rib 3o and engages with a recess 31 provided on the outer peripheral side of the convex rib 3o. 3
4 is provided, and the engaging piece 33 of this rubber sheet 34 is engaged with the recess 31 provided on the outer peripheral side of the convex rib 3o of the heated pan 11, so that the entire convex rib 3o is wrapped by the rubber sheet 34, and the rubber sheet 34 is made of rubber. The sheet 34 is configured to be fixed to the heated pan 11.

To explain the operation in the above configuration, the rubber sheet 34
The rubber sheet 34 is heated by wrapping the entire convex rib 3o of the heated pot 11 and engaging the engaging piece 33 of the rubber sheet 34 with the recess 31 provided on the outside of the convex rib 3o of the heated pot 11. It is fixed to the pot 11 so that it does not easily fall off during use, so if the user accidentally removes the top plate 1.
3 KM heating, il! Even if 111 is dropped, the convex rib 3o
Since the rubber sheet 34 surrounding the entire structure is a cushion, there is no risk of damage to the ceramic top plate 13. In addition, the heated pot 11 can be temporarily fixed to the main body 21 by engaging the convex rib 30 of the heated pot 11 with the outer periphery 2° of the top plate 13 via the rubber sheet 34.
Even if the food placed in the heated pot 11 is stirred during cooking, the heated object #111 does not move horizontally horizontally on the ceramic top plate 13 having a smooth surface every time it is stirred. It makes cooking safer and easier. Furthermore, since a gap 22 is formed between the heated pot 11 and the top plate 13 by the thickness of the rubber sheet 34, the heat generated in the heated pot 11 by the magnetic flux generated from the heating coil 12 is directly transferred to the top plate. Because it is not conveyed to 13,
It is possible to prevent the temperature of the top plate 13 from rising, and to protect the interior of the main body 21, which is provided with the heating coil 12° high frequency control board 17 and the like, which are sensitive to high temperatures, from heat. Further, although high frequency vibrations are generated in the heated pot 11 due to the magnetic flux generated from the heating coil 12, the rubber sheet 34 can prevent abnormal noises such as chattering between the heated pot 11 and the top plate 13.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the heated pot is temporarily fixed to the top plate via the rubber sheet provided on the heated pot. Even when stirring the food put in the cooking pot, the heated pot does not move every time it is stirred, making cooking easier.

In addition, the rubber sheet cushions the impact between the heated pot and the top plate, thereby providing an easy-to-use induction heating cooker that can prevent damage to both.
