And a thermistor 7 for detecting the temperature in the firing chamber for performing process determination and temperature adjustment. Also,
At the top of the baking chamber 1, there is a lid 8 and a yeast inlet 9 for introducing yeast, and the yeast inlet 9 drops the yeast by an interlocking solenoid 10. Operations such as cooking start and cancellation are performed by the operation unit 11, and a control device 12 configured by a microcomputer or the like in accordance with an operation from the operation unit 11 controls all the baking according to a signal from the thermistor 7, and performs cooking. LCD or L depending on the progress
The display means 13 constituted by an ED or the like is turned on or off.

In an automatic bread maker having such a configuration,
In the conventional cooking process, as shown in FIG. 16, the time during which the ingredients for the bread are kneaded is set such that the kneading time is shortened if the detection temperature of the thermistor 7 is high in order to prevent a rise in temperature due to kneading. On the other hand, if the kneading time is too short, the gluten is not generated sufficiently, and the bread swelling becomes insufficient. Therefore, if the temperature is 25
At temperatures above ℃ and when cooking French bread, precautions were taken to use cold water for the ingredients, so that the kneading time was extended so that sufficient gluten was produced.

[0004]

In such a conventional automatic bread maker, if the user inadvertently forgets the contents of the precautionary statement, or even if the user remembers it, it is not easy to determine whether the temperature is higher than 25 ° C.

By providing the control device 12 for turning off the "use of cold water" when the use of the cold water is displayed while "use of cold water" is displayed,
When cold water must be used, the use of cold water can be used to confirm that the user has made the correct material selection.

Embodiment 4 Hereinafter, an embodiment of the invention according to claim 4 will be described with reference to the drawings. FIG. 10 is a partially cutaway sectional view showing the configuration of this embodiment. Note that the third embodiment shown in FIG.
The same components as those described above are denoted by the same reference numerals, and description thereof is omitted.
In the figure, a start switch 11b for starting cooking is provided in the operation means 11. In addition, a buzzer 18 is installed on the control device 12 as cold water unused notification means for issuing a warning sound to the user. FIG. 11 is a circuit diagram showing the configuration of this embodiment. In the figure, the buzzer 18 is connected to the notification control means 12g, and is turned on by the notification control means 12g.
Do off.

The interrelationship and operation of the above components will be described with reference to the drawings. FIG. 12 is a flowchart showing the operation of this embodiment. In the figure, first, at step 12, the control device 12 determines whether or not the start switch 11b has been pressed and cooking has started. If cooking is not started, the process returns to step 12. Conversely, if the cooking has started, the process proceeds to step S13. In step 13, the display control means 12d determines whether or not the cold water use display means 13a is turned on. If there is no need to use cold water and the cold water use display means 13a is not turned on, the process ends. Conversely, since cold water must be used, if the cold water use indicator 13a is turned on, the process proceeds to step 14. In step 14, the buzzer 18 is sounded by the notification control means 12g assuming that cooking has started even though "use of cold water" is displayed.

As described above, according to the present embodiment, the buzzer 18 for giving a warning sound, the notification control means 12g for controlling on / off of the buzzer 18, and the start switch 11b for displaying "use cold water" By providing the control device 12 that sounds the buzzer 18 when is pressed, the user can be notified that the cold water use display has been overlooked even when cooking is mistakenly started even though cold water must be used for the material. Therefore, cooking mistakes due to forgetting to use cold water can be prevented.

Embodiment 5 Hereinafter, an embodiment of the invention according to claim 5 will be described with reference to the drawings. FIG. 13 is a circuit diagram showing the configuration of this embodiment. The same components as those of the fourth embodiment shown in FIG. In the figure, a cold water unused stop means 12h for temporarily stopping the cooking process is installed in the control device 12.

The interrelationship and operation of the above components will be described with reference to the drawings. FIG. 14 is a flowchart showing the operation of this embodiment. In the figure, first, at step 15, the control device 12 determines whether or not the start switch 11b has been pressed and cooking has started. If cooking is not started, the process returns to step 15. Conversely, if the cooking has started, the process proceeds to step S16. In step 16, the display control means 12d determines whether or not the cold water use display means 13a is turned on. If there is no need to use cold water and the cold water use display means 13a is not turned on, the process ends. Conversely, since cold water must be used, if the cold water use display means 13a is turned on, the process proceeds to step S17. In step 17, the buzzer 18 is sounded by the notification control means 12g assuming that cooking has started even though "use of cold water" is displayed. In step 18, the cooking process is stopped by the cold water unused stop means 12h so that loads such as the heater 2 and the motor 4 are not driven. In step 19, the input of the start switch 11b is waited. If the start switch 11b is not input, the process does not proceed to step 20. In step 20, it is determined that the user has restarted after confirming the ingredients and the like, and the bread cooking process is restarted.

As described above, according to the present embodiment, the provision of the cold water non-use stopping means 12h for temporarily stopping the cooking process allows the cooking process to be started even if the cooking is mistakenly started during the display of the use of the cold water. It is possible to prevent agitation and heating of the material without proceeding, to easily exchange water and cold water, and to continue cooking again, which is convenient.
