Description

[Detailed Description of the Invention] <Industrial Application Field> This invention has a strong heating means and a weak heating means.
! The rest relates to a porridge cooking device in which only the weak heating means is energized.

<Prior Art> Recently, there has been a strong demand for multi-functionality in rice cookers, and as a type of multi-functionality, rice cookers that have the function of cooking porridge are now being provided.

Initially, this type of porridge cooking device was designed to achieve the basic function of boiling water by adding a large amount of heat V, and then maintaining the boiling state by adding a small amount of heat M. In addition, a timer means is provided to set the time required for cooking the porridge (the time from the start of cooking to the completion of cooking).

<Problems to be Solved by the Invention> With the above-mentioned conventional porridge cooking device, the time set by the timer means is the time from the start of cooking to the completion of cooking, so depending on the quality of the porridge, the porridge may not necessarily be delicious. The problem is that it is not always possible to do so. To be more specific, in order to cook delicious porridge (it is known that it is best to cook delicious porridge in 22 to 27 minutes after boiling, the conventional J5 porridge mentioned above is known to be best). In this case, it is only possible to control the time including the time for boiling m+1rj, and the time required for FJ8MA varies considerably depending on the amount of water and rice. a3 The time from Hu: 11≧ to the end of cooking, which has the greatest influence on the cooking of porridge, cannot be accurately controlled, and it does not necessarily mean that the porridge will be delicious. This will cause the problem that there is no such thing.

<Object of the invention> This invention was made in view of the above problems,
To provide a porridge cooking device which can cook delicious porridge by accurately controlling the time from boiling to the end of cooking.

Means for Solving the Problems> In order to achieve the above object, the boiling detection means of the present invention may be one that detects the steam temperature like TR8, or one that detects the steam itself like a steam sensor. Those that do can be used.

Further, the energization switching means may be one that energizes only the weak heating means based on the boiling detection signal from the boiling detection means, and for example, a relay or the like can be used. Further, the timer means may be of any type as long as it controls the energization time only to the weak heating means based on the boiling detection means, and for example, a timer motor may be used as the driving source.

<Function> With the porridge cooking apparatus having the above configuration, the heating means is initially energized at least b strong to rapidly back warm the porridge.

When it boils, the boiling detection means outputs a boiling detection signal, so the energization switching means operates to energize only the weaker heating means to continue the boiling state without boiling over. The timer means can operate to control the duration of energization only to the weak heating means. Namely, water,
Regardless of the amount of rice, the duration of the boiling state without boiling over can be controlled by the timer means.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 1 is an electric circuit diagram showing an embodiment of the porridge cooking device of the present invention.

), a series circuit consisting of a timer drive source (4b), and a normally closed relay contact (7C) are connected in parallel to each other. A normally open relay contact (7d) is connected in parallel with the power switch (1), and each of the relay contacts (7d) is connected in parallel with the series circuit consisting of the main heater (2) and the relay contact (7a). 7a)(7b)(
7c) A series circuit consisting of a relay coil (sword) for driving (7d) and a TRS (31) for steam temperature detection is connected.

The timer contact (4a) is turned on at the same time as the timer drive source (4b) starts to be energized, and turned off when a predetermined set time has elapsed. is set at 22 to 27 minutes.

In the 13 porridge cooking device with the above configuration, by turning on the power switch (1), the relay coil (7)
becomes energized, the relay contact (7a) turns on, and the main heater (a) is energized.Since the main heater (2) generates a large amount of heat, it is housed in a steel case (not shown). The heated rice and water can be rapidly heated to a boiling state.When the boiling state is reached, T RS (6), which is sensitive to the above temperature, is turned off.
This cuts off the power to the relay coil (7), so
At the same time as cutting off the power to the main heater, the relay contact (7bH7C) turns on and the timer drive source (4b
) is energized and the timer contact (4a) turns ON, so
After that, by energizing the sub-heater (5),
It is possible to continue boiling without sagging. The continuation of this boiling state is stopped by turning off the timer contact (4a) when the energization time to the timer drive source (4b) reaches a preset predetermined time.

Furthermore, malfunctions caused by the restart of T RS (6) are reliably prevented by T RS [31].

In other words, regardless of the rice and water stored in the pot, the boiling state at the above temperature is detected by TRS (61), and the boiling state without boiling over is maintained for a predetermined period of time set from 22 to 27 minutes. Since it can be made to continue cooking, delicious porridge can be cooked regardless of the amount of rice cooked by the mother.
