Description

[Detailed description of the invention] The present invention relates to a rice cooker for rice that can be cooked immediately without washing.

Conventional rice cookers wash rice before cooking, but the present invention is intended for rice that does not need to be washed, and can greatly reduce household labor at home.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is the main body, with a measuring rice bin layer on the top and a rice cooker layer on the bottom.

2 is an outer heating element, 3 is an inner heating element, 4 is a pot, 5 is a protective frame, 6 is a heating element support frame, 7 is a center thermostat, 8
1 is a lever linked to the center thermostat 7, 9 is a switch button, and 10 is a completed contact plate.The movement of the center thermostat 7 is received by the lever 8, and the start and completion of rice cooking is determined by the closing and opening of the contacts built in. conduct.

Reference numeral 11 is a display board that incorporates 12 neon lamps.

13 is the door, 14 is the door handle, 15 is the door reversing spring,
It has a function in which a spring force acts naturally in accordance with the opening/closing operation of the door 13.

16 is a door rotating plate, and a reversing spring 15 is attached to the tip.

17 is a rice cooking lid that covers the top of the pot 4.

18 is a slide plate of the pot 4, which is welded to the main body 1 by spot welding or the like.

A pot handle 19 is attached to the top of the pot 4.

20 is a door switch that turns off both ends of the power when the door is opened, maintaining safety.

21 is a door rotation axis.

22 is the lid of the main body, and 23 is the bottom plate of the rice jar, which has a thin shape.

24 is a transparent plate used as a peephole to see the remaining amount of rice from the outside, and 25 is a gasket for attaching the transparent plate 24, which is made of silicone rubber or the like.

26 is a rice measuring valve, and 27 is a measuring valve mounting plate, which is made of a spring material and presses the rice measuring valve against the rice bin bottom plate 23.

28 is a rice measuring valve mounting screw, and 29 is a rice scattering prevention plate, which prevents rice from remaining on the measuring valve mounting plate 27.

30 is a rice metering solenoid valve, and the operating time is measured as the amount of rice.

31 is a rice guide plate having a thin shape, and pours measured rice into the pot 4.

32 is a heat shield plate that prevents steam from entering the rice pot when cooking rice in pot 4, and prevents the rice from rising in temperature and deteriorating its taste.

33 is a water solenoid valve that can be programmed in advance to supply water according to the amount of rice.

34 is a pipe, 35 is a shower faucet, and the water outlet has a convex surface toward the pot 4, and supplies water in a shower state.

36 is a control circuit that supplies the amount of rice and the amount of water using a selection switch 37.

38 is a selection switch mounting plate.

39 is a high heat thermostat.

40 is a pot insertion confirmation switch.

41 is attached to the pipe 34 with a moisture-proof backing to prevent steam from entering the rice bin.

Next, the operation in the above configuration will be explained.

Hold the pot 4 by the door handle 14, open the door 13, and place it in the rice cooking layer of the main body 1.

By inserting the pot 4 into the main body 1, the upper part of the pot 4 turns on the pot insertion confirmation switch 40.

When the door 13 is closed, the door switch 20 is turned on.

When you select and press the selection switch 37 the amount of rice you want to cook and the amount of water to achieve the desired hardness, the control circuit 36 memorizes it.
First, the rice measuring electromagnetic valve 30 is activated and presses the measuring valve mounting plate 27 downward, creating a gap in the thin center of the rice measuring valve 26 and the rice bin bottom plate 23, from which the rice falls downward.

The amount of rice is measured by the time that the rice measuring solenoid valve 30 is working.

When the electricity to the rice measuring electromagnetic valve 30 is stopped, the rice measuring valve 26 is pressed upward by the spring force of the measuring mounting plate 27, and the gap between it and the rice bin bottom plate 23 disappears, and the measuring of rice is completed.

The rice that has fallen downward is put into the pot 4 through the rice cracker inner plate 31 and the rice cooking lid 17.

30 to 60 seconds after the rice is put into the pot 4, the water solenoid valve 33 is activated and the amount of water stored in the control circuit 36 is supplied through the selection switch 37.

In this case, the rice is fed into the pot 4 in the shape of a mountain, even if the center part is fed, and when feeding water, it is best to make the rice as flat as possible to improve the quality of the rice. When feeding into the pot 4, the shower shape eliminates the need to level the surface with a motor or the like.

When the supply of water is completed, the completed contact plate 10 is turned on manually or automatically to start cooking rice.

The shower faucet 35 can be completed manually or automatically by contact plate 1.
0 is turned ON and moves downward to cover the opening of the rice cooker lid 17.

In this case, the rubber gasket 4 attached to the pipe 34
1 also closes the opening of the rice cracker inner plate 31, preventing steam from entering the rice bin or the rice cracker inner plate 31 during cooking.

At the beginning of rice cooking, the inner heating element 3 is heated.

When the temperature of the rice reaches around 45° C. and the bottom of the pot 4 reaches 45 to 55° C., the high heat thermostat 39 is turned on, and the inner heating element 3 and the outer heating element 2 cook rice at high heat.

This is point a on the rice cooking temperature curve in FIG.

When the rice becomes rice, the water at the bottom of the 4th pot disappears, and the bottom of the 4th pot becomes 10
The center thermostat 7 is activated when the temperature starts to rise above 0° C. and is suitable for charring, and the completed contact plate 10 is turned off through the lever 8, completing the rice cooking.

This is point b on the rice cooking temperature curve in FIG.

■Make the flour evenly and the rice is ready.

Although the configuration and operation have been explained above, when supplying rice and water, the moisture-proof packing 42 and the shower cylinder supply rice from the rice cracker inner plate 31 and the rice cooking lid 17, as shown by the dotted line in FIG. Supply water.

When cooking rice, the position of the solid line is lowered, rice cracker inner plate 31, rice cooking lid 1
7 is prevented by the moisture-proof backing 41 having elasticity such as rubber and the folds on the outer periphery of the shower tube, so that the rice is not deteriorated or soiled due to moisture in the rice pot, and rice can be cooked efficiently.

After rice cooking is completed, the rice cooking lid 17 of the shower faucet is moved above the rice cooking lid 17 of the shower faucet in conjunction with the door 16, so that it can be easily taken out.

As is clear from the above explanation, the fully automatic rice cooker of the present invention has a simple structure, supplies rice and water, and can also be moisture-proofed by packing etc.
