シールするようになっている（第１図）。First, the lid heater (20) is attached to the upper surface of the heat sink (18), the heat expansion plate (19) is stacked on top of the lid heater (20), and the shaft (41) is caulked and fixed together. Next, the peripheral part (32
), and insert the peripheral part (32) from the bottom side into the lid frame plate (17).
) in the seal groove (31). And the screw (36
) to the through hole (35) of the heat sink (18) and gasket (43).
) and screw it into the lid frame board (17). At this time, the thin part (34) connecting the peripheral part (32) and the annular part (33) is deformed into a limp shape as shown in FIG. As a result, the annular portion (33) moves independently without being restricted by the peripheral portion (32) and is fixed following the fixed position of the screw (36). Similarly, by tightening the six screws (36), the heat sink (18) is fixed to the lid frame plate (17) with the packing (43) interposed. Thereafter, the assembled lid frame plate (17) as shown in Figure 2 is attached to the bottom of the lid (10), and the inside of the lid (10) is sealed and can be opened and closed by the hinge (11). It is attached to the main body case (1). In addition, when the lid (1o) is closed,
The "dog-shaped" portion at the tip of the peripheral portion (32) of the packing (43) comes into pressure contact with the flange of the inner pot (5) to form an elastic seal (FIG. 1).

通電か自動的に停止される。When the rice cooking start time corresponding to the reserved meal time arrives, the timer of the microcomputer is activated and the switch is turned on, and the rice cooking heater (3) and the lid heater (20) are energized and generate heat. As a result, the heat from the lower rice cooking heater (3) and the upper lid heater (20) work together to virtually heat the entire surface of the water (81) and rice (82) inside the inner pot (5). It will start. Rice cooking starts by heating the lid heater (20) and the rice cooking heater (3), and the temperature of the water (81) in the inner pot (5) rises to generate steam. Cook rice or boil water (81) or boil the inner pot (5)
When the water content in the rice cooker decreases and the temperature rises rapidly, the sensor (4) is activated and the power to the rice cooking heater (3) and lid heater (20) is automatically turned off or stopped.

られる。As a result, the rice (82) will be cooked in the inner pot (5), and the rice will be cooked evenly and ready to eat at the reserved time, and you can start serving it. When the push button (16) on the top surface of the lid (20) is pressed, the lid (20) is pressed by the elastic force of the hinge spring (13).
) automatically rotates around the hinge shaft (2), the top surface of the main case (1) is opened, and freshly cooked rice is served.

い。In addition, in the above-mentioned embodiment, the hinge part (] of the lid body 10)
1) is equipped with a hinge spring (13) and the lid (10) is automatically opened using the push button (16). The present invention can also be applied to a type rice cooker. Also,
Although the gasket (43) is shown to be approximately square with rounded corners, it may be round, and the number of annular portions (33) is not limited to six.

定作業が簡単で部品数も少なくなり工数が減−っで製作
費も低下する。As a result, since the annular portion of the packing is connected to the peripheral portion through the thin wall portion, it is not restricted by the annular portion and moves independently according to the fixing position of the screw. Therefore, even though the annular part is made integral with the surrounding part, the heat dissipation plate can be fixed in the same manner as conventional screws with a seat plate attached. Since no parts are used, the fixing work is simple, the number of parts is reduced, man-hours are reduced, and manufacturing costs are also reduced.
よって、本発明によれば、構成が簡単で、製作費が安価
