Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric rice porridge cooker, and more particularly, to an electric rice porridge cooker controlled by a microcomputer capable of surely and stably cooking delicious rice porridge with simple cooking control. Is.

[0002]

2. Description of the Related Art Electric rice porridge cookers currently on the market are provided with a heater at the bottom of an inner pot, and heating power is supplied to the heater to cook porridge.

Further, for the purpose of cooking delicious porridge, the temperature of the porridge cooking pot is measured by a controller equipped with a temperature sensor and a microcomputer as shown in FIG. An electric rice porridge cooker controlled by a microcomputer has been developed, which is input to a microcomputer to determine the porridge cooking capacity and perform appropriate power control according to the cooking capacity. An electric porridge cooker that cooks under the control of a microcomputer performs cooking process control such as a water absorption process, a cooking capacity determination process, a cooking process, and a boiling maintenance process in sequence under the program control of a microcomputer, and the porridge is in an optimal state. After cooking and porridge cooking control, the heat retention control state is entered. Thus, in the electric rice porridge cooker controlled by a microcomputer, the control of the cooking process can be finely controlled by the program control, so that delicious rice porridge can be cooked.

[0004]

However, in the conventional microcomputer-controlled electric rice porridge cooker, as shown in FIGS. 20 and 21, the water absorption step gradually raises the temperature until it reaches 40 ° C. Since the water is absorbed for a certain period of time, there is a problem that the water absorption time “varies” depending on the water temperature, and does not match the set time of the timer for cooking reservation (set cooking reservation time).

In the conventional cooking process of porridge, as shown in FIG. 22, heating is started along a standard cooking curve for a while after heating is started, and cooking capacity (total number) is judged. Since it is cooked up to the boiling point, there is a problem that the cooking time until it is placed on the standard cooking curve has "variation" and does not match the time set by the timer for the cooking reservation system.

[0006] In this way, when the time does not match the set time of the timer for cooking reservation, for example, if the rice is cooked earlier than the cooking reservation setting time, the taste will be improved at the cooking reservation setting time (at the time of notification of cooking). It has changed or has become paste-like.

If the cooked rice is cooked later than the reserved cooked time, the cooked rice may not be completely cooked at the cooked reserved time (at the time of notification of cooked food).

The present invention has been made to solve the above problems, and an object of the present invention is to prepare an electric rice porridge cooked by a microcomputer capable of adjusting the cooking at a preset cooking reservation time. To provide a container.

The above and other objects and novel features of the present invention will become apparent from the present specification and the accompanying drawings.

A timer for setting a water absorption time, a certain time is set in the timer, the timer is started from the start of porridge cooking and the water absorption step is started, and the water absorption step is ended when the certain time elapses; Within the set water absorption time, the first heater heating power control means for sequentially lowering the heater heating power in response to the temperature rise of the inner pan and the standard cooking curve for determining the temperature rise of the inner pan until boiling are set. Reference cooking curve setting means to
During the cooking process, the temperature of the set reference cooking curve and the detected inner pot temperature are constantly compared, and the heating power of the heater is controlled so that the temperature of the inner pot rises along the reference cooking curve. An electric porridge cooker characterized in that a second heater heating power control means for performing is provided.
