Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker, and more particularly to a rice cooker equipped with a mechanical timer that uses the rotational torque for rewinding a mainspring.

[0002]

2. Description of the Related Art Generally, a rice cooker used at home includes a rice cooker equipped with a mechanical timer. This rice cooker is not limited to rice cooked with white rice, but also cooked rice or ramen,
You can also make fruit sake and rice porridge. And, for the cooked rice of white rice, there are "reserved cooked rice" where the rice is sharpened and then the rice is reserved at the cooking time and cooked. Divided into
Two methods are used according to the usage status.

In the reserved rice cooking, the rice cooking is started in accordance with the set time of the timer, so that the immersion time of the rice becomes longer and the rice grains absorb water sufficiently to cook delicious rice. On the other hand, with instant rice cooking, rice is cooked immediately after it has been sharpened, so the water absorption time of the rice will be shortened, and water absorption will be limited to the surface of the rice grain, and rice will be cooked insufficiently.
Rice with core, that is, raw rice is often cooked.

[0004]

As described above, the rice cooker equipped with the conventional mechanical timer has a time of about 2 and 30 minutes after the rice is sharpened in order to eliminate the raw cooked rice. There was a way to cook rice by turning on the rice cooker switch after emptying. However, when such a cooking method is used, it is necessary to constantly monitor the time, which is extremely troublesome, and there are inconveniences such as variations in the cooked condition. In addition, neglecting to monitor the time also delayed the meal time, which could interfere with the subsequent action plan.

The present invention has been made in order to solve the above problems and provides a rice cooker which adds water absorption time to the instant rice cooking scale of a timer and automatically causes rice to absorb water before starting rice cooking. It is intended to be provided.

[0006]

SUMMARY OF THE INVENTION A rice cooker according to the present invention comprises a timer shaft composed of a fixed portion provided with a time scale including an instant rice cooking scale on substantially the same circumference, and a knob provided with an index facing the time scale. A movable part provided with a dial for rotating rice to set the rice cooking time, and a timer having a mainspring that is wound around the timer shaft by the knob of the movable part and gives a reversing torque to the movable part by rewinding force. In the rice cooker provided with, the water absorption time is added to the instant rice cooking scale on the fixed part of the timer.

[0007]

[Function] Put rice and water in the pot inside the rice cooker, close the outer lid, pull the knob of the timer and turn the dial clockwise, adjust the knob to the instant rice cooking scale, and press the rice cooking switch. At this time, the contactor disposed inside the main body of the timer is engaged with the engagement hole displaced by the angle Δθ corresponding to the water absorption time by the spring pressure. Then, the timer rotates the dial counterclockwise due to the restoring force of the mainspring, and when the knob returns to the rice cooking scale immediately after the water absorption time, the dial rotation stops and rice is cooked to cook the rice in the pot. increase.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an external view of an embodiment of the present invention, FIG. 2 is a structural explanatory view showing a cross section of a main portion thereof, FIG. 3 is a front view of a timer according to the present invention, and FIG. 4 is related to the present invention. It is a structure and operation explanatory view of a timer.

In the drawing, 1 is a main body case having an open top and a pot accommodated therein, 2 is an outer lid for covering the opening of the case 1, 3
Is a handle provided on the outer lid 2, 4 is a push button, 5 is a steam port provided on the outer lid 2, and 6 is a hinge. When the outer lid 2 is lifted while holding the handle 3 and pushing the push button 4, the outer lid 2 is rotated about a hinge 6 to open the inside. Reference numeral 7 is a display lamp arranged on the side surface of the case 1, 8 is a timer, and 9 is a rice cooking switch.

The timer 8 is composed of a dial 81 and a scale plate 82, and the dial 81 is a fitting hole 11 of the case 1.
, The scale plate 82 is formed in an annular shape and is fitted into the fitting hole 11
It is provided around. A protruding knob 83 is formed on the dial 81, and an index 84 is attached near the upper surface of the knob 83. Further, the scale plate 82 is provided with a scale 85 including an instant rice cook scale and a numeral 86. Numeral 87 is a timer shaft, numeral 88 is a dial mounting hole, numeral 89 is a mounting plate, and numeral 80 is a body of the timer 8 mounted inside the case 1 by a mounting plate 89.

The main body 80 of the timer 8 is composed of a fixed portion 80a and a movable portion 80b. The movable portion 80b is provided with a contact b1 and a spring b2 that pushes the contact b1 in the circumferential direction at a position corresponding to the index 84, and the contact b1 is a knob 83.
Is linked to. The fixing portion 80a is provided with an engagement hole a1 with which the contact b1 is engaged. The engagement hole a1 is formed by being offset by a Δθ angle from the position corresponding to the instant rice cooking scale “cooking / warming” of the scale 85, and the Δθ angle corresponding to a water absorption time for rice grains to absorb moisture, for example, 30 minutes. Minutes are added.

Next, the operation of the present invention will be described. First, in the case of instant rice cooking, the ground rice and an amount of water corresponding to the amount of rice are put in a pot in the case 1, the outer lid 2 is closed, and the power cord is plugged into an outlet. Then, the scale 85 shown in FIG.
Knob 8 with index 84 matching X1 corresponding to "OFF"
3 with the dial 81 centered around the timer shaft 87
From the scale 85 to X2 corresponding to "rice cooking / heat retention", the angle 84 is turned clockwise, and the index 84 is adjusted to X2. Then, the rice cooking switch 9 is pressed.

At this time, the mainspring arranged inside the main body 80 is wound around the timer shaft 87, and the contact b1 also becomes X.
Move up to 2. Then, the moved contact b1 rotates by X3, that is, a Δθ angle, while pressing the circumferential wall of the fixed portion 80a that is obliquely cut by the spring pressure, and engages with the engagement hole a1.

The timer 8 set for instant rice cooking rotates the movable portion 80b counterclockwise by the rotational torque for rewinding the mainspring, and returns the contact b1 to X2. When the contact b1 returns to X2 after a lapse of water absorption time of 30 minutes, for example, the rotation of the dial 81 is stopped and a rice cooking heater (not shown) is energized to start cooking rice in the pot. ..
When the rice is cooked, the heater is de-energized and the rice is kept warm.

In the above embodiment, the engaging hole a1 of the fixed portion 80a is provided by being shifted from the instant rice cooking scale by a Δθ angle corresponding to a water absorption time of 30 minutes. Is not limited, and since the water temperature changes depending on the season, the Δθ angle may be appropriately changed and provided, for example, by increasing the water absorption time.

[0016]

As described above, according to the present invention, since the water-absorption time is added to the instant rice cooking scale of the fixed portion of the timer, the rice is automatically made to absorb water without monitoring the time. It is convenient because you can start cooking rice afterwards. In addition, it is possible to cook high quality rice with no variation in how the rice is cooked.
