Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rice cooker for general household use.

(Prior Art) Conventionally, this type of rice cooker had a configuration as shown in FIG. In the figure, the temperature inside the rice cooker is detected by temperature detection means 11 and outputted to rice cooking control means 12. Thereby, the rice cooking control means 12 controls the rice cooking operation in the rice cooking means 13. When the temperature inside the rice cooker is low,
The rice cooking operation is performed by increasing the electric power by increasing the energization rate to the rice cooking heater of the rice cooking means 13, or by lowering the electric power to the rice cooking means 13 when the temperature inside the rice cooker becomes high. The display means 14 displays the rice cooking operation currently being performed. The display drive means 15 outputs information on the rice cooking operation of the display means 14 based on the output of the rice cooking control means 12.

(Problems to be Solved by the Invention) In the conventional configuration described above, when the lid is opened during the rice cooking operation and an attempt is made to put ingredients such as cooked rice into the rice cooker, the temperature inside the rice cooker temporarily drops. When you close the lid, the temperature inside the rice cooker rises, but if you continue cooking when the temperature drops, there is a drawback that the rice cooker may turn on too much power or operate in a way other than its intended cooking operation. there were.

SUMMARY OF THE INVENTION An object of the present invention is to provide a rice cooker that eliminates the drawbacks of the conventional rice cooker and does not start cooking even if the temperature inside the rice cooker drops temporarily until the lid is closed and the temperature inside the rice cooker rises. It is.

(Means for Solving the Problems) The rice cooker of the present invention includes a rice cooking means consisting of a rice cooking heater, a rice cooking heater switch, and a rice cooking means that changes the ratio of the time of energization and stoppage of the rice cooking heater. In addition, the rice cooking control means outputs the output to the rice cooking means, the display means displays the operation being performed by the rice cooking means, and the output of the rice cooking control means
A display driving means for displaying information on the display means, a switch attached to the rice cooker, and each time the switch is operated,
The stop means has a function of alternately outputting to the rice cooking control means an output for stopping the operation of the rice cooking control means and an output for continuing the operation of the rice cooking control means that had been stopped.

(Function) According to the above configuration, by operating the stop means before opening the lid of the rice cooker, even if the temperature inside the rice cooker drops temporarily, the lid is closed and the temperature inside the rice cooker rises. Since the rice cooking operation can be stopped until the rice cooking time is reached, the original rice cooking operation can be continued without turning on too much power to the rice cooking heater.

(Example) An example of the present invention will be described based on FIGS. 1 and 2. FIG. 1 is a block diagram of the rice cooker of the present invention. In the figure, 1 is a rice cooking means that performs a rice cooking operation, 2 is a rice cooking control means that controls the rice cooking means 1, 3 is a display means that displays the rice cooking operation being performed by the rice cooking means 1, and 4 is a rice cooking means 2. This is display driving means that drives the display means 3 by output. 5 is a switch attached to the rice cooker, 6
By switching the switch 5, the rice cooking control means 2
This is a stopping means that alternately outputs to the rice cooking control means 2 an output to stop the operation of the rice cooking control means 2 and an output to continue the operation of the rice cooking control means 2 which has been stopped.

FIG. 2 is a circuit diagram of the rice cooker of the present invention. In the figure, 7 is a commercial power source, and the rice cooking means 1 is a rice cooking heater 1a.
, a relay contact 1b, and a relay coil 1c. The relay coil 1c is energized and controlled by the rice cooking control means 2, and the relay contact 1b is controlled to open and close. As a result, the rice cooking heater 1a is controlled to be energized to perform the rice cooking operation. 4 is a display drive means which drives the rice cooking process display on the display means 3 by the output of the rice cooking control means 2.

The stop means 6 is composed of a resistor 6a and a resistor 6b, and when the switch 5 is open, the resistor 6b causes the rG
The rice cooking control means 2 operates by being connected to the NDJ. When the switch 5 is closed, the voltage of the ratio of the resistor 6a to the resistor 6b is connected to the rice cooking control means 2, and the operation of the rice cooking control means 2 is stopped.

When the switch 5 is opened again, the rice cooking control means 2 continues the operation immediately before stopping.

(Effects of the Invention) According to the present invention, the original rice cooking operation can be continued by stopping the rice cooking operation of the rice cooking means, opening the lid of the rice cooker, and restarting the rice cooking operation after closing the lid. This has the effect of providing more delicious food.
