Description

[Detailed description of the invention] [Industrial application field] This invention relates to a rice cooker equipped with a miso soup cooker, and it is possible to cook both rice and miso soup, which are often eaten at the same time at breakfast, using the rice cooker. By performing preparatory operations the day before the desired operation, the food will be ready at the desired time, such as the next morning, thereby reducing the burden of early morning cooking work.

[Prior Art and Problems Therewith] When breakfast is mainly rice, miso soup is often served as an accompaniment, and when preparing a meal, it is necessary to make miso soup in addition to cooking the rice.

Traditionally, the rice cooking process and the miso soup cooking process were performed independently, and by setting a timer, the rice can be cooked at the desired time.
By using a so-called timer-type rice cooker, you can set the rice the day before and have it ready the next morning. In other words, there is no need to wake up early in the morning to start cooking rice.

However, even if rice cooking in the early morning is no longer necessary, the need to make miso soup to accompany breakfast still forces the work to be done early in the morning. Even if it were possible to do so, it would lose much of its meaning.

[Purpose] The present invention was developed in view of the above points, and it is possible to make both rice and miso soup by preparatory operations performed the day before the rice cooker is to be operated, and then prepared at the desired time, such as the next morning. The purpose is to reduce the burden of early morning cooking work by ensuring that the food is ready.

[Means] The technical means of the present invention taken to achieve the above object are "a rice cooking gas valve 30 that opens and closes a gas circuit to a rice cooking burner 31, and a miso soup cooking burner 41.
Miso soup cooking gas valve 40 that opens and closes the gas circuit to
A reservation timer for setting the cooking start time, and a control device 2 to which the output of the reservation timer 1 is applied are provided. The rice cooking gas valve 30 opens the other miso soup cooking gas valve 40 when the internal temperature of the rice cooking pot 3 reaches a predetermined value.
The valves are closed when the opening time of 0 reaches a certain value or when the temperature inside the miso soup pot 4 reaches a certain value.

[Effect] The above technical means works as follows.

When setting up the rice cooker, set the reservation timer 1 the day before you plan to start the rice cooker.

When time elapses and the reservation timer 1 times up, the time-up signal is applied to the control device 2, which causes the control device 2 to turn on the cooking gas valve 30.
The miso soup cooking gas valve 40 is opened. That is,
The rice cooking burner 31 and the miso soup cooking burner 41 are combusted, and the rice cooking work and the miso soup cooking work begin.

When the miso soup cooking burner 41 burns and the miso soup cooking process progresses, and when this cooking time reaches a certain value, or when the temperature inside the miso soup pot 4 reaches a predetermined value, the control device 2 controls this. Upon detection, the miso soup cooking gas valve 40 is closed. This results in
The miso soup cooking burner 41 to which gas has been supplied via the miso soup cooking gas valve 40 is extinguished, and the miso soup cooking ends.

On the other hand, when the rice cooking process that is progressing at the same time as the miso soup cooking is nearing its end and the temperature inside the rice cooking pot 3 reaches a predetermined value, the rice cooking gas valve 30 is opened and the corresponding rice cooking burner 31 is extinguished. . That is,
The rice cooking process is completed.

As mentioned above, according to the technical means of the present invention,
Both the rice and the miso soup can be prepared at the desired time, such as the next morning, by making advance preparations, such as the day before the device is to be operated.

[effect] The present invention has the following unique effects.

Both rice and miso soup can be prepared at the desired time, such as the next morning, by preparatory work performed the day before the equipment is to be operated, so that they can be made and served at the same time. The burden of early morning cooking work for making a large amount of rice and miso soup can be reduced.

[Embodiment] The embodiment of the present invention is “Miso soup cooking gas valve 4”.
A delay circuit was provided in the signal transmission path to open the zero.

According to this embodiment, the miso soup cooking gas valve 4
Since a delay circuit is provided in the transmission path of the signal for opening 0, the time lag between the completion of the rice cooking operation and the miso soup cooking, which is generally completed before the rice cooking, is reduced. That is, the cooking of miso soup is completed much earlier than the completion of cooked rice, and the quality of the miso soup is less likely to deteriorate before the cooked rice is ready.

[Example] Next, an example of the present invention described above will be described in detail with reference to the drawings.

As shown in FIG. 1, a reservation timer 1 is provided downstream of the power switch 5, and the output of the reservation timer 1 is connected to a switching transistor 12.
is applied to the base of.

The switching transistor 12 is used to supply power to the control device 2, etc., and the emitter side output of the switching transistor 12 is connected to a miso soup amount setting device 42 consisting of a variable resistor 31, etc., and a timer 44 for cooking miso soup. Miso soup cooking switch 4
9. Further, the emitter side output of the switching transistor 12 is applied to a reference value setting device 35 and the like for setting the opening timing of the rice cooking gas valve 30 via the rice cooking switch 39.

The miso soup cooking gas valve 40 that opens and closes the gas circuit to the miso soup cooking burner 41 has a second miso soup cooking gas valve that compares the output of the miso soup amount setting device 42 and the timer 44.
It is opened and closed by the output signal of the comparator 47,
On the other hand, the rice cooking gas valve 30 that opens and closes the gas circuit to the rice cooking burner 31 is connected to the output of the thermistor 38 as a temperature sensor that detects the internal temperature of the rice cooking pot 3;
The first one that compares the output of the reference value setter 35 described above.
It is designed to be opened and closed by the output signal of the comparator 37. In addition, in this example,
Immediately downstream of the miso soup cooking switch 49,
A delay circuit 48 is provided to delay the start time of miso soup cooking from the start time of rice cooking.

Now, when pre-cooking rice and miso soup, set both rice cooker switch 39 and miso soup cooker switch 49.
All you have to do is set it to the ON state, set the cooking start time using the reservation timer 1, and then turn on the power switch 5.

When the power switch 5 is turned on, when the time set by the reservation timer 1 has elapsed, a time-up signal is output from the reservation timer 1 and the switching transistor 12 is turned on.

When the switching transistor 12 is turned ON and its emitter output is output, the first comparator 37 compares the output of the thermistor 38 that detects the temperature inside the rice cooker 3 with the output of the reference value setter 35. An "H" output is output from the first comparator 37, turning on the second transistor 36, thereby opening the rice cooking gas valve 30. That is, the rice cooking burner 31 is ignited by an igniter (not shown) and begins to burn.

On the other hand, when the switching transistor 12 is turned on, the signal is delayed by a certain period of time in the delay circuit 48. When the time has elapsed, the second comparator 47 starts comparing the outputs of the miso soup amount setting device 42 and the timer 44, and immediately turns on the third transistor 46 to open the miso soup cooking gas valve 40. . That is, the miso soup cooking burner 41 is ignited by an igniter (not shown) and begins to burn.

Next, the output of the timer 44 is set to the miso soup amount setting device 4.
When the value set in step 2 is exceeded, the second comparator 47 outputs an "L" output, which causes the miso soup cooking gas valve 40 to close.
The miso soup cooking burner 41 is put into the extinguished state and the miso soup cooking is completed.

On the other hand, by the time the miso soup is finished, the rice cooking process is nearing its end, and the temperature inside the rice cooker 3 rises, causing the negative potential of the thermistor 38 that detects the temperature inside the rice cooker 3 to reach the reference value. When the set value of the setting device 35 is exceeded, the third transistor 36 is turned off, and the rice cooking gas valve 30 is closed. That is, the rice cooking burner 31 is turned off and the rice cooking is completed.

In addition, in the above example, miso soup cooking and rice cooking can be performed independently,
When only rice cooking is to be performed, the rice cooking switch 39 is set to the ON state, and conversely, when only miso soup cooking is to be performed, only the miso soup cooking switch 49 is set to the ON state.

Further, in the above embodiment, the timing for extinguishing the miso soup cooking burner 41 at the end of miso soup cooking was based on the combustion time of the burner, but the temperature inside the miso soup pot was detected and the timing for extinguishing the miso soup cooking burner 41 was determined by It may also be configured to stop when the temperature reaches a boil.

In addition, as shown in FIG. 2, the output of the second comparator 47, which is output when the temperature inside the miso soup pot 4 reaches a certain value (for example, 100°C), is sent from the mono-multivibrator 94 to the first differential circuit 92 via the first differentiating circuit 92. 2 Differential circuit 93
The miso soup burner 40 may be closed by applying the voltage to the reset terminal of the flip-flop 95 via the .

In such a case, the miso soup burner 41 is extinguished after a certain period of time (the set time of the mono-multivibrator 94) has elapsed since the inside of the miso soup pot 4 boiled.
