EXAMPLES ( Reference Example 1) Hereinafter, a first reference example of the present invention will be described with reference to FIGS. The same components as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted.

In FIG. 1 and FIG. 2, 19 is a control device for controlling energization of the heater 3, the motor 7, etc. by a relay, a semiconductor switching element, etc. according to a control pattern for a rice cake cooking process programmed in a microcomputer. It is operated by the switch unit 20. Reference numeral 21 is a temperature sensor fixed to the boiler 4 for detecting the temperature of the boiler 4 and inputting it to the control device 19. The control device 19 uses the temperature information and the measurement time from the temperature sensor 21 according to a program and uses the heater 3 and the motor 7. Are in control. The operation switch unit 20 has four switches, “off”, “musu”, “tsuku / normal”, and “tsuku / soft”, and the “musu” switch connects the heater 3 to the controller 19 continuously. When the temperature sensor 21 detects an increase in temperature when the water in the boiler 4 is evaporated and emptied by energization,
The heater 3 is set to a pattern that informs the end of the process with a buzzer or the like, and the "tsuku / normal" switch continuously energizes the motor 7 for a certain time (for example, 10 minutes) to obtain a standard mochi rice cake, Use a buzzer or similar pattern to notify the completion, and use the "Tsuku / soft" switch to continuously energize the motor 7 for a certain period of time (for example, 12 minutes) to obtain a soft mochi rice cake. The "off" switch is set to cancel these operations in the pattern for notifying the completion.

Next, the operation of this reference example will be described. In the electric rice cake making machine configured as described above, water is supplied to the boiler 4 to prepare the rice cake, and the seal member 11, the hopper 6 and the blades 13 are attached to the hopper 6.
Put rice cake in and close the lid 16. The steaming process is started by the "musu" switch of the operation switch unit 20, the heater 3 is energized 100% to steam the sticky rice, and when the boiler 4 is empty, the heater 3 is cut off and the buzzer sounds and stands by. Then, the power is turned off with the "OFF" switch and the lid 16 is removed. Then, in the attaching process, one of the courses "Tsuku / Normal" and "Tsuku / Softer" is selected. In the soaking process, the longer the soaking time within an appropriate range, the softer the rice cake will become without straining. Depending on the difference, a normal or soft rice cake can be obtained according to taste. A mochi with a normal texture is suitable for kagami mochi etc. because it is strong and does not easily lose its shape. The softer one is suitable for applications such as Noshi mochi.

In this reference example, the control pattern was explained in which the energizing rate of the motor 7 was constant at 100% in the "giving step", and the quality of the rice cake was changed by changing the adhering time. You may change the mochi by changing the number of rotations when making it. Also, the steaming process may be divided into courses, and the motor 7 may be moved slightly to move the sticky rice only during the steaming process in the soft rice cake course, so that the whole rice is softly steamed without uneven steaming.

% Gradually decreasing (for example, 80% after 20 minutes),
When the water out of the boiler 4 is detected, the heater 3 is turned off and a buzzer or the like is used to notify the end of the process. "Normal / Tsuku", "Soft seaweed / Tsuku", "Off"
The switch is the same as that of the first embodiment, and when the lid 16 is manually removed and steamed in the "normal / musu" course, "normal / tsuku" is selected, and in the case of the "softmeat / musu" course Select "Soft and Tsuku".

[0017] By doing the above, the "soft rice / musu" course, in which the energization rate is reduced even when the amount of water supplied to the boiler 4 is constant, results in a longer steaming process time and more sticky rice. Since it is steamed softly, it is possible to select and cook rice cakes of different quality, which are usually soft, without any manual effort. In this reference example, the difference in softness of the rice cake depending on the course is obtained because the addition process is changed in addition to the steaming process, but the steaming process may be performed alone. In addition, the heater 3 is first used in the "soft turtle / musu" course.
100% is energized in order to reduce the time it takes for the water in the boiler 3 to boil so that the steam spreads over the sticky rice and begins to steam effectively, so that the difference in cooking time between the courses does not become too large. Is.
