Description

  The present invention relates to an automatic bread maker that can make cooking bread to which an auxiliary material such as raisins is added.

  In the traditional automatic bread machine, in order to make cooking bread with the addition of dried fruits, cheese, nuts and other auxiliary materials, the “mix call” buzzer is sounded at the stage where the dough is gathered in the kneading process. There is known a technique for informing the timing of charging (Patent Document 1).

By the way, such buzzer notification is not necessary except when cooking bread is made, and when making normal bread, the buzzer sound is annoying or the device is misidentified. In this regard, it is only necessary to set up a dedicated course for making cooking pans and to make a buzzer notification only when this cooking course is selected. However, there is a problem that the memory load is large and the course selection operation becomes complicated.
Japanese Patent No. 3655940

  In view of the above, an object of the present invention is to provide an automatic bread maker that can select whether or not to notify the timing of charging the secondary material and solve the above problems.

  In order to solve such a problem, the present invention provides a bread container in which bread ingredients are stored, a kneading means for kneading bread ingredients stored in the bread containers, and a bread container during kneading operation by the kneading means. In an automatic bread maker provided with an informing means for informing the timing of adding a secondary material such as raisins, a selecting means for selecting whether to activate the informing means, and a confirmation means for confirming the selection contents of the selecting means It is equipped with.

  Further, when the notifying means is operated, it is provided with a control means for driving the kneading means at a low speed, and is provided with a stopping means for stopping the operation of the notifying means on the way.

  According to the present invention, since the notification means can be prevented from operating except when making a cooking pan to which the auxiliary material is added, there is no discomfort or distrust due to notification during bread making. . In particular, in bread making using a reservation timer, a situation where a buzzer sounds during the night can be prevented.

  Moreover, when performing the notification, the kneading means is rotated at a low speed at the notification timing, so that the secondary material can be evenly scattered over the bread dough. In addition, since the notification of material input can be stopped when it is noticed, there is no discomfort due to the continuous notification.

  The automatic bread maker shown in Example 1 below.

A heater 20 is disposed substantially horizontally so as to surround the pan case 9 below the inside of the oven case 3. A temperature sensor 21 is attached to the wall surface of the oven case 3 from the side where the motor 4 is provided, and monitors the internal temperature of the oven case 3.

  FIG. 2 is a block diagram showing a control system of the present invention. The circuit board 7 includes a microcomputer board 23 having a microcomputer 22 and an operation panel 8, and a power board 26 having a transformer 24 and a buzzer 25. The microcomputer 22 has a built-in memory 27 in which an execution program for each breadmaking course is stored, and an operation panel 8 and a power board 26 are connected to the power board 26. The heater 20 is connected. As a result, the program is read from the memory 27 in accordance with the bread making course selected on the operation panel 8, and the motor and heater are controlled in accordance with this program.

  The operation panel 8 includes an LCD display panel 28, a course selection key 29 for selecting a bread-making course, a timer key 30 for setting a reservation timer time, a start key 31 for starting the operation, and stopping the operation. A stop key 32, a baked color selection key 33 for selecting a baked color, and a natural yeast key 34 for selecting a bread making course using natural yeast are provided. The display panel 28 displays a segment display portion 28a for displaying a course number, time until completion of the bread making process, various error codes, and the like, and a portion corresponding to the process being executed among the bread making processes indicated on the upper part outside the panel frame. A process display unit 28b for displaying, a natural yeast display unit 28c for displaying a portion corresponding to the course selected by the natural yeast key 34 in the bread making course of the natural yeast described in the lower part outside the panel frame, and a baked color selection key A burnt color display portion 28d for displaying the burnt color selected in 33 is provided. Reference numeral 35 denotes a list showing bread making courses that can be selected with the course selection key 29. Here, bread making courses 1 to 13 are shown. Each time the course selection key 29 is input, the number of the bread making course is displayed on the segment display portion 28a of the display panel 28, so that the desired bread making course is selected in light of this list 35. Of course, there is no limit to the number of courses.

A method of using the automatic bread maker of Example 1 configured as described above will be described.
First, an amount corresponding to the bread for making bread material is put into the bread case 9 and attached in the oven case 3. When the course selection key 29 on the operation panel 8 is input after the power is turned on, the character “1” indicating the bread bread course is displayed on the display unit 28. This number corresponds to each course shown in the bread making course table 33, and every time the course selection key 29 is input, the display is “2” → “3” →... “13” → “1”. Since the transition is made sequentially, the user selects a desired bread making course by number. When the course number returns to “1”, a sound different from the other feed sounds is output to support the operability of the visually impaired.

  When making a reserved bread using a timer, the timer key 30 is input after selecting a course and the time until the bread making is completed is set. Since the display on the display unit 28 is switched from the menu number display to the time display by the input of the timer key 30, the time can be set using the up key and the down key. When the series of settings are completed and the start key 31 is pressed, a bread making operation corresponding to the selected course is executed. If the bread making is to be started immediately, the start key 31 may be input as it is after selecting the course.

  Subsequently, the bread making operation of the automatic bread maker according to the first embodiment will be described using a bread course as an example. FIG. 3 is a time chart of the bread course.

"Material set"
Set the bread case 9 with flour, sugar, salt, fat, skim milk, yeast, and water. When using the reservation timer, in order to prevent the water and yeast from touching, first swell flour and other ingredients into a chevron at the center of the bread case 9, add water around it, dent the top, and enter the yeast. To.

"Timer process"
When the reservation timer is set, the bread case 4 filled with the bread material is left as it is until the bread making operation is started. During this time, when the outside air temperature is low, such as in winter, heater control is performed to keep the inside of the oven case at a freezing prevention temperature in order to prevent the material from freezing. In order to prevent the temperature of the dough after kneading, when the remaining timer time is 2 hours, the heater control is performed so that the temperature to be kept is determined according to the temperature in the oven case at that time and the temperature is kept at that temperature. Is called. In this embodiment, the maximum timer time Tmax including the time until baking is set to 16 hours regardless of the bread making course.

"Kneading process"
In the process of kneading the bread material in the bread case, the motor 4 is driven and the kneading blade 11 is rotated. In the bread bread course, the steps of primary kneading-preliminary fermentation-secondary kneading are executed for times T1, T2, and T3, respectively. In the primary kneading, motor control is performed in which the rotational speed of the motor 4 is increased stepwise in order to gradually mix the separated bread ingredients. In the pre-fermentation, heater control is performed to keep the inside of the oven case at a constant temperature, and the dough is rested and settled. In secondary kneading, motor control is performed in which the dough squeezed by pre-fermentation is raised again, and the rotation speed of the motor 4 is intermittently rotated at a high speed-medium speed in order to strengthen the gluten.

  When a predetermined time before the secondary kneading ends, for example, 5 minutes before, the buzzer 25 sounds and a “mix call” is performed to urge the addition of secondary materials. The mix call sounds the buzzer 25 ten times at regular intervals, and is set to a volume that can be noticed even if the buzzer 25 is far away from the device. When the mix call sounds, motor control is performed to rotate the motor 4 at a low speed for a time t3 in preparation for charging of the secondary material. When the time t3 has elapsed, the secondary ingredients are finished by rotating the motor 4 at a high speed in order to mix the added sub-material into the bread dough.

  The mix call can be stopped while it is ringing when the stop key 32 is input. In addition, since the mix call is not necessary except when the auxiliary material is added during kneading, in the first embodiment, a setting that prevents this mix call can be made. The setting method will be described later.

"Fermentation process"
The oven case is maintained at the yeast fermentation temperature and the bread dough is expanded, and is divided into three times of primary fermentation, secondary fermentation, and shaped fermentation, which are executed for times T4, T6, and T8, respectively. And heater control is performed so that it may hold | maintain to the respectively prescribed fermentation temperature during this process.

"Degassing process"
It is a step of crushing the dough swelled in the fermentation process, removing gas in the dough and taking in oxygen to increase the activity of yeast, and is performed after time T5 and time T7 after primary fermentation and after secondary fermentation, respectively.

"Baking process"
The process of baking bread is performed for time T9. In order to immediately stop the activity of yeast, the heater is continuously energized first, the temperature of the pan case is increased at once, and then the heater control is performed so that the baking temperature is reached.

  Now, with regard to the setting not to make the above-mentioned mix call, the start key 31 is pressed again before the mix call sounds in the state where the bread making course (here, bread making courses 1 to 6) where the mix call sounds is started. Enter it. In other words, if the reservation timer is set, the start key is pressed again from the time of the timer process until the secondary training where the mix call sounds. Enter it.

  In order to determine whether the mix call is performed or not, the display on the display panel 28 is changed as shown in FIG. That is, it changes depending on whether the colon “:” of the clock display is blinked or lit. When blinking, it indicates that there is a mix call, and when lit, it indicates that there is no mix call. It should be noted that these key operations / display modes are not limited, and it is needless to say that a dedicated key or display unit may be provided, or another key / display may be used.

  An automatic bread maker that can switch the mix call on and off.

It is an internal sectional view showing the composition of the automatic bread maker of the present invention. It is a block diagram which shows the control system of the apparatus. It is a time chart figure which shows the operation | movement of the bread-bread course of the apparatus. It is explanatory drawing which shows the example of a display of the presence or absence of a mix call.
