Reference numeral 25 denotes a leaf spring fixed near one end of the lever 22. Although not shown, a ball is inserted between the leaf spring 25 and the articulating plate 24 and clicked. The lever 222 is brought into contact with the concavo-convex portion 24a of the articulation plate 24 by elastic force, and the lever 222 is rotated in stages by movement.

One tip of the lever 22 has the aforementioned operation button.
4 is fitted.

A rice cooking operation using a rice cooker having such a configuration will be explained.

First, put polished rice 14 and an appropriate amount of water 15 into the rice cooking container 12, cover the top lid 12a, and place the rice in the concave part 1 of the saucer 13.
3a and place it on the housing 1 together with the saucer 13 as shown in FIG.
Place it on the net shelf 7 inside.

Then, as shown by the dashed line in FIG. 4, the upper heater 9.9 is lowered to a predetermined position, that is, at position 1 within the range where the upper cover 12a cannot be removed by the clamps 11 and 11, and at this time it is connected to the upper heaters 9 and 9. The reflected plate 10 also lowers at the same time, and the volume of the cooking space changes.

This operation is carried out by operation number 14.

That is, when the operating lever 4 is manually lowered from the state shown in FIG. 5, the fixed bottle 21 is used as a fulcrum, and the lever 22 rotates counterclockwise in FIG. Move the pin 20 downward.

This pin 20 is fixed to the guided part 17a of the hanging fitting 17 and lowers the hanging fitting 17 along the guide rod 18, so the reflecting plate 10 and the reflecting plate 1 fixed to the hanging fitting 11 are fixed to each other.
The upper heaters 9, 9 held at zero move downward by the same distance as the pin 20.

Further, the tip of the lever 22 is held in a predetermined position by fitting into the recess of the ball adjusting plate 24 by the elastic force of a leaf spring 250 provided at the tip by pressing a button in the gap between the adjusting plate 24 and the guide plate 23. .

After setting the upper heaters 9, 9 and the reflector plate 10 at predetermined positions, the time switch 5 is set to the rice cooking side position, for example, 15 minutes, as shown in FIG. 2, and power is supplied to the upper and lower heaters 8, 9 to start rice cooking.

At this time, the volume of the burying space becomes smaller due to the lowering of the reflecting plate 10, and the temperature rising in the space can be accelerated.

The gap between the front end of the reflector plate 10 and the front door 2 is wider than the gap between the rear end and the back plate 6A, and its length in the vertical direction is shorter, so there is a cooking space where the button can be pressed when cooking rice. The steam and heated air inside flows toward the front door 2 side with less flow resistance and leaks into the escape space through the gap.

For this reason, a force U is generated that flows in the direction of the glass plate 2b, which is easily cooled, so that the temperature of the glass plate 2b can be increased, and the temperature in the cooking space can be made approximately equal.

Therefore, uneven cooking of rice can be prevented. In addition, steam and hot air leaking into the escape space flow from the front to the rear of the upper surface of the reflector 10 through the flow holes 6a+1a to the outside, heating the upper surface of the reflector 10 and preventing cooking. It can prevent the temperature drop in the space.

During such rice cooking, the upper lid 12a does not come off because the upper lid 12a is prevented from moving upward by the attachment ILll which floats due to the steam pressure inside the rice cooking container 12.

Incidentally, the hold down 11.degree. 11 also has the role of guarding the upper heaters 9,9.

When the rice cooking time has elapsed and the time switch 5 reaches the OFF position, a notification device such as a chime notifies the end of the rice cooking time and the power supply to the upper and lower heaters 8 and 9 is cut off.

Then, the time switch 5 further rotates counterclockwise in FIG. 2 and enters the cooking period, in which cooking is performed by the residual heat in the cooking space.

Then, when the murashi period ends, a chime sounds to notify you that the rice is ready.

When the rice is cooked, open the front door 2.

Then, the net shelf 7 linked to the front door 2 moves to the front and the saucer 1
3 and the rice cooking container 12 are exposed to the outside of the housing 1.

Then, the rice-cooking container 12 is taken out together with the saucer 13 by pinching it with a take-out tool (not shown) for the saucer 13.

On the other hand, since it has the same structure as a conventional cooking device such as a toaster oven, it can also be used as a cooking device. When grilling, etc., the rice cooking container 12 can be used as a grilling plate.

At this time, the time switch 5 is prevented from rotating counterclockwise in FIG. 2 from the OFF position by a lock button (not shown), and the time is set at the button rice cooking position.

As described above, the present invention has the structure of a conventional cooking device such as a toaster oven, so it can be used not only for cooking rice but also for other types of cooking, making it extremely versatile and convenient.

Furthermore, since the volume of the cooking space can be changed, it is possible to provide a rice cooker that can optimally cook rice according to the amount of rice to be cooked.
