DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail. FIG. 1 is a sectional view of a rice cooker according to the present invention. FIG. 2 is a view in which a lid body of the rice cooker is opened, and a heat sink and a seal packing integrally attached to the heat sink are removed.

In the drawing, 1 is a main body, 2 is an inner pot, 3 is a heating means,
4 is a lid body, 5 is a cover in a lid, 6 is an induction heating coil,
7 is a cover outside cover, 8 is a heat sink, 9 is a fitting claw, 10 is a seal packing, 11 is a steam port, 12 is a control part, and 13 is a hinge part. In this configuration, an inner pot 2 is detachably inserted into the main body 1, and a heating means 3 for heating the inner pot 2 is provided below the main body 1. A lid body 4 is provided on the main body 1 so as to be openable and closable about a hinge 13, and an induction heating coil 6 is fixed above the lid inner cover 5 of the lid body 4, that is, on the side opposite to the surface facing the inner pot 2. I have. A cover outer cover 7 is fixed to the cover inner cover 5 so as to cover the upper surface of the cover inner cover 5 and the induction heating coil 6. A radiator plate 8 is detachably fixed to the lid inner cover 5 by fitting claws 9 provided at a plurality of locations. Seal packing 1 on heat sink 8
0 is fixed and can be attached and detached integrally with the heat sink 8. The seal packing 10 is in contact with the upper end surface of the inner pot 2 over the entire circumference when the lid body 4 is closed, and seals the steam generated in the inner pot 2 during rice cooking so as not to leak from other than the steam port 11. A control unit 12 is provided inside the main body 1 and is electrically connected to the induction heating coil 6 and the heating means 3 to control the energization thereof.

Next, the operation will be described. The user puts the washed rice and an appropriate amount of water into the inner pot 2, inserts it into the main body 1, and inserts the lid body 4 (the lid outer cover 7, the lid inner cover 5, and the induction heating coil 6 fixed to the lid inner cover 5). When the radiator plate 8 is integrated and the rice cooker switch (not shown) is operated, the heating unit 3 is operated by the control unit 12.
Starts the heating operation (rice cooking) of the inner pot 2.

At the same time, the control section 12 starts energizing the induction heating coil 6. When a current is applied to the induction heating coil 6, a high-frequency magnetic field is generated, and the radiator plate 8 is induction-heated to generate heat. This heats the rice and water inside the inner pot 2 also from the lid (heat radiating plate). When the water starts to boil, bubbles containing the starchy substance dissolved from the rice (neba) are generated and adhere to the radiator plate 8. No bubbles overflow. In addition, the seal packing 10 and the upper end surface of the inner pot 2 and the heat sink 8
Is sealed (closed), so that foam does not overflow around the inner pot 2. When the rice finally absorbs all the water and cooks the rice, the heat radiating plate 8 is heated by the induction heating coil 6 to dry the wetness due to the attached bubbles and to dry the condensation of the steam generated from the cooked rice. 8 is kept dry. After the steaming, when the user opens the lid, the heat sink 8 is dry, so that dew does not drip onto the main body 1 and become dirty. However, as a result of heating and drying the bubbles during cooking, the heat radiation plate 8 is contaminated with the dried rice cake.

When the user keeps warm after cooking rice,
The radiator plate 8 is slightly heated by controlling the energization of the induction heating coil 6 by the control unit 12, and is kept at a substantially constant temperature to keep the rice warm and prevent condensation of the radiator plate 8 by steam generated from the rice.

When the user cleans the rice after keeping it warm,
When the fitting claw 9 is operated and bent to release the fitting with the heat radiating plate 8, the heat radiating plate 8 can be removed from the lid inner cover 5.

Since the seal packing 10 is attached to the heat sink 8, the seal packing 1 is integrated with the heat sink 8.
0 also falls off. Since the heat radiating plate 8 is configured to generate heat by the induction heating coil 6, there is no electric component (heater) or the like which causes a failure when wet, and the heat radiating plate 8 made of, for example, stainless steel capable of induction heating and the seal made of, for example, silicone rubber Since only the packing 10 is used, the washing is easy. Therefore, it is possible to easily remove dirt from the foam by washing with a sink or soaking. Since the electric components such as the induction heating coil 6 of the lid are protected by the lid inner cover 5, even if the heat radiating plate 8 is attached to the lid inner cover 5 with the water droplets attached to both surfaces of the heat radiating plate 8 after the round washing, the water droplets are not removed. Can be dried by induction heating of the heat radiating plate 8 at the time of the next rice cooking without reaching electric components.

[0014]

As described above, according to the structure of the present invention, a radiator plate (and a seal packing) is detachably attached to the cover in the lid, and the radiator plate is heated by the induction heating coil provided inside the lid. Therefore, the electric heater fixed to the heat radiating plate as in the related art becomes unnecessary, and the heat radiating plate (and the seal packing) can be washed off by removing the electric heater from the lid. As a result, the cleaning performance is significantly improved, and the sanitation is extremely sanitary as compared with the conventional configuration in which the fixed heat sink is wiped with a cloth.

In this embodiment, the radiator plate is detachably supported by the fitting claws provided on the inner cover of the lid. A method may be used in which a portion protruding to the side is provided, and a heat sink is detachably fixed to this portion. The point is that the radiator plate can be removed from the lid, and this radiator plate satisfies the requirements of the present invention as long as it is heated by an induction heating coil provided inside the lid.
