Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a rice cooker, in particular a simple backing configuration (l
The purpose is to provide a rice cooker that cooks delicious rice by increasing the temperature of the rice cooker inside the pot.

Conventional configuration and its problems In conventional rice cookers, a backing provided on the outer periphery of the lower surface of the lid was brought into contact with the flange of the pot, but this did not increase the cooking temperature in the pot. However, it was not enough to cook delicious rice.

OBJECT OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks of the conventional methods, and an object of the present invention is to increase the temperature inside the pot of a rice cooker.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a pot having a step formed at the top and a flange around the outer periphery of the step, a heating element for cooking rice on which the pot is placed and heated, and a pot. A lid that covers the opening on two sides, a pot outer backing that is attached to the outer periphery of the lower surface of the lid and comes into contact with the flange of the pot, an inner lid that is installed on the lower surface of the lid, and a backing that is attached to the outer periphery of the inner lid. It is equipped with an inner lid backing that comes into contact with the stepped part of the pot, and a cushioning material that presses the inner lid backing against the stepped part of the pot through the inner lid, and keeps the inside of the pot under pressure during cooking. It's something that looks like it's dripping.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is the main body and the bottom part is the curling ring and the lower frame 2
is connected to form the completed main body. 3 is a protective frame whose upper edge is connected to the main body 1 by a frame 4. 1 frame 4 is caulked into the upper part of main body 1 and is molded from glass-filled nylon resin or the like having poor heat conductivity. 5 is a heating element for rice cooking, which heats the bottom of the pot 6. The temperature at the bottom of the pot 6 is detected by the center thermostat, and the rice cooker lever 24 is turned on and off with the completed contact plate 25.

Reference numeral 8 denotes a heat-retaining heating element attached to the second part of the protective frame 3. 9 is the inner lid, which is placed on the upper edge of the pot.
0 is a steam cylinder and has a force of 7 on the outside M14. 1
1. This is a steam cylinder backing that is placed over the steam cylinder 10 and prevents slime from the pot 6 from entering the outer lid 14. Reference numeral 12 denotes an inner lid backing, which is pressed against the stepped portion of the pot 6 and serves to raise the inner portion of the pot 6. Reference numeral 13 denotes a cushion rubber to which the inner cover 9 is attached, and the cushion presses the inner cover 9 downward. An outer lid 14 covers the pot 6 and the inner lid 9 together with an outer lid cover 39. The outer cover frame is an auxiliary material when assembling the outer cover 14 and the outer cover cover 39. Reference numeral 16 denotes a pot outer periphery backing assembled between the outer lid frame 16 and the outer lid cover 39. usually,
Inner lid backing 12, cushion comb 13, guide tube 11
The pot outer circumferential backing 16 is made of elastic and heat-resistant silicone rubber.

17 is a hook lever, and the hook lever 1P is attached to the outer lid frame 15.
II] 19, and 18 is a biasing spring for the hook lever 17. 20 is a bijiyo and has a melon that catches Tsunofre...-17. Outer lid 14,
By fitting the inner lid 9 with the hook lever 17, it is closed and locked. Reference numeral 21 denotes a hinge, which allows the outer cover 14 to be attached and rotated by the hinge shaft 22, and by unlocking the hook lever 17 from the display 20, the cover can be opened and closed. 23 is a dew catcher for preventing dew droplets from falling onto the floor surface on the inner lid 9. 40 is a lid cutter (C131 material is glued to the outer lid cover 39/ζ lid heating element, 32 is a lid shaft for removing the inner lid 9 through the cushion rubber 13).

27 is a display plate, which is attached to the main body 1 by the display plate mounting screw 29.
Vζ is installed. 28 is a display lamp. 26
is a rice cooking button attached to the tip of the rice cooking lever 24. 30 is a cord reel attached to the bottom surface of the main body 1; 33 is a main body side insulating material; 34 is a main body bottom insulating material; 35 is an outer lid handle cover.

37 is a back plate incorporating the coat reel 30.

This is J-dosisochi.

Next, after explaining the operating procedure, press the rice cooking button 26.
The FK lever 24 is held in one direction by the suction force of the center thermostat 7. At this time, complete contact plate 2
5 is turned on, and the heating element 6 for rice cooking (ζ = the pot 6 is heated by applying an electric current. It enters the pot 6) r-chi. The temperature of the rice and water rises, and the rice is completed. The temperature at the bottom of the pot 6 rises, the center thermostat 7 operates, and the rice cooking lever 24
is pushed down and the contacts of the completed contact plate 25 are turned OF.
In state F, the heating element 5 for rice cooking and the heating element 8 for keeping warm are connected in series and the state shifts to keeping warm. Pressed against the upper step. Since the inside of the pot e is sealed by the inner lid backing 12, the boiling point inside the pot 6 rises by about 1°C. Pregelatinization of rice takes about 20 to 26 minutes at 98°C, but 1
By increasing the temperature by °C, rice with a simpler structure and more stickiness and elasticity than before can be obtained.

Since the elasticity of the cushion rubber 13 and the inner lid backing 12 is used, the temperature inside the pot θ can be easily controlled even with a carrier handle type, and a pressure-type rice cooker with good operability can be obtained.

To open the lid, use a small hole (diameter 0.3) that does not affect pressurization.
~005u) on the inner lid 9, the effect remains the same. This hole can also prevent the pot 6 from becoming depressurized due to negative pressure.

In addition, as the inside of the pot 6 becomes pressurized, the entire pot 6 expands outward, which improves the adhesion between the pot 6 and the rice heating element 5, which reduces uneven cooking. It will be done.

Effects of the Invention] - As is clear from the explanation, according to the present invention, the inner lid backing attached to the outer periphery of the inner lid is placed on the stepped part of the pot, and the inner lid backing is attached to the inner lid through the cushioning material. Since the rice is pressed against the step part of the pot, the cooking temperature in the pot rises, making it possible to cook delicious rice with stickiness and elasticity.
