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
is a lever linked to the center thermostat 7, 9 is a switch button, and 10 is a mature 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 built-in contacts. 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, and when the door is opened, both ends of the power supply are 0FFL, 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 bin, 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.

Reference numeral 28 indicates a rice measuring installation screw, and 29 indicates 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.

Reference numeral 31 denotes the inner plate of the rice cracker, which has a thin shape and is used to pour measured rice into the pot 4.

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

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 which 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 a moisture-proof gasket attached to the pipe 34 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 the rice and operates the rice measuring solenoid valve 30, pushing the measuring valve mounting plate 27 downward. A gap is created 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 during the time when the rice measuring solenoid valve 30 is working is measured.

When the electricity to the rice metering solenoid valve 30 is stopped, the rice metering valve 26 is pressed upward by the spring force of the metering valve mounting plate 27.
There is no gap with the rice pot bottom plate 23, and the measurement 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.

After 30-6 minutes of rice being put into the pot 4, the water solenoid valve 33 is activated and stored in the control circuit 36 through the selection switch 37.

amount of water is supplied.

In this case, the rice is fed into the pot 4 in the shape of a mountain because it is fed from the center, and it is best to make it as flat as possible when water is fed to improve the quality of the rice. ,
When water is supplied into the pot 4, the need for leveling the surface with a motor or the like is eliminated by supplying water in the form of a shower.

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 moves downward when the completed contact plate 10 is turned on manually or automatically, and covers the opening of the rice cooker lid 17.

In this case, the rubber gasket 4 attached to the pipe 34
1 closes the opening of the rice cracker inner plate 31 and prevents 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 cooked, the water at the bottom of the pot 4 disappears, and the temperature at the bottom of the pot 4 begins to rise above 100 degrees Celsius.The center thermostat 7 is activated at a scorching temperature, and the completed contact plate 10 is turned OFF through the lever 8.
and cooking is completed.

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

Mix the flour by 1 flour and the rice is ready.

Further, when rice is supplied to the pot 4, the center of the rice tends to rise because it is supplied from the center.

If you cook rice in this state, the rice will be cooked unevenly and it will be difficult to make delicious rice.

Therefore, when water is supplied, instead of simply sending it into the pot 4, a shower faucet 35 is provided at the tip of the pipe 34 so as to send water in a shower-like manner.

By discharging the water in such a way that it flattens the rice, it is possible to cook rice without uneven cooking.

As is clear from the above explanation, since the fully automatic rice cooker of the present invention is equipped with a shower faucet at the end of the water supply pipe, the surface of the rice is flattened, so that rice can be cooked evenly.
