It is configured to display time information indicating the set driving time.

  Next, a control flow of the motor 51 by the control unit 10 when the kneading process is selected by the process selection key 21 f will be described. FIG. 4 is a flowchart showing an example of a control flow of the motor 51 by the control unit 10 in the kneading step. FIG. 5: is a graph which shows an example of a displacement of the rotation speed per unit time of the kneading blade 7 in a kneading process.

  When driving the motor 51 from the stopped state in the kneading step, the control unit 10 generates the rotation driving force smaller than the specific range regardless of the rotation driving force selected by the level selection key 21g. 51 is configured to control.

  First, the kneading process is selected by the process selection key 21f (step S1).

  Next, the level of the rotational driving force of the motor 51 is selected by the level selection key 21g, and the driving time (mixing process time) of the motor 51 is set by the time setting key 21e (step S2).

  Next, the start of the kneading process is instructed by the start key 21b (step S3). Thus, the control unit 10 controls the driving of the motor 51 based on the temperature detected by the temperature sensor 9 to perform the kneading process.

  At the start of the kneading process, the kneading blade 7 is in a state in which the rotation is stopped. Therefore, the control unit 10 controls the motor 51 so as to generate a rotational driving force smaller than the rotational driving force according to the level 1, and rotates the kneading blade 7 at low speed for m seconds (for example, 30 seconds) Step S4). Thereby, the scattering of the cooking material such as the flour, water, and yeast in the kneading container 6 is suppressed.

  Thereafter, the control unit 10 determines whether or not a pause is instructed by the start key 21b during the driving time set by the time setting key 21e ("NO" in step S5 and step S6). When a temporary stop is instructed by the start key 21b, the control unit 10 controls the motor 51 to stop to stop the rotation of the kneading blade 7 ("YES" in step S6 and step S7). During this temporary stop, for example, cooking materials such as wheat flour and water, and auxiliary materials such as raisins can be added to the kneading container 6. The control unit 10 continues to stop the rotation of the kneading blade 7 until the restart is instructed by the start key 21 b.

  Thereafter, when restart is instructed by the start key 21b, the control unit 10 rotates the kneading blade 7 at low speed for m seconds (for example, 30 seconds) (return to step S4). Thereby, the scattering of the cooking material such as the flour, water, and yeast in the kneading container 6 is suppressed.

  Further, the control unit 10 determines whether or not the level has been changed by the level selection key 21g during the driving time set by the time setting key 21e ("NO" in step S5 and step S9). If the level is changed by the level selection key 21g, the control unit 10 determines whether the kneading blade 7 is rotating (step S10).

  When the kneading blade 7 is not rotating, the control unit 10 rotates the kneading blade 7 at low speed for m seconds (for example, 30 seconds) regardless of the level changed by the level selection key 21g (return to step S4). As a result, for example, it is possible to suppress the scattering of cooking materials such as wheat flour and water and auxiliary materials such as raisins added to the kneading container 6 during the kneading step.

  When the kneading blade 7 is rotating, the control unit 10 controls the motor 51 to rotate the kneading blade 7 so as to generate a rotational driving force according to the level changed by the level selection key 21g ( Return to step S11 and step S5). FIG. 5 shows a state in which the level is changed to be high by the level selection key 21g (for example, changed from level 2 to level 3) while the kneading blade 7 is rotating.

  If the set driving time has elapsed without the level being changed by the level selection key 21g and the temporary stop being instructed by the start key 21b, the control unit 10 ends the kneading step (step S5). "YES", "NO" in step S6, and "NO" in step S9).

  Next, a control flow of the display unit 22 and the time setting key 21e by the control unit 10 when the kneading process is selected by the process selection key 21f will be described. FIG. 6 is a flowchart showing an example of the control flow of the display unit 22 and the time setting key 21 e by the control unit 10 in the kneading step. FIGS. 7A to 7D are diagrams showing display examples displayed on the display unit 22 when the kneading process is selected by the process selection key 21 f.

  The control unit 10 is configured to limit the drive time of the motor 51, which can be set by the time setting key 21e, to a range equal to or less than the preset maximum drive time according to the level selected by the level selection key 21g. It is done. Here, when the level of the rotational driving force of the motor 51 is “level 1” to “level 3”, the maximum driving time is 20 minutes or more (for example, 30 minutes). Further, when the level of the rotational driving force of the motor 51 is "level 4", the maximum driving time is 15 minutes.

  Further, when the control unit 10 changes the level by the level selection key 21g, if the drive time set by the time setting key 21e immediately before the change is larger than the maximum drive time after the change, the control unit 10 changes it as time information. Is configured to cause the display unit 22 to display the maximum driving time. Furthermore, when the driving time set by the time setting key 21e immediately before the change is equal to or less than the maximum driving time after the change, the control unit 10 sets the driving time set by the time setting key 21e immediately before the change as time information. Are displayed on the display unit 22.

  First, the kneading process is selected by the process selection key 21f (step S21). As a result, as shown in FIG. 7A, the character portion of "Neri" lights up or flashes on the display unit 22 as the process information. Here, it is assumed that “1 minute” is displayed on the display unit 22 as the initial value of the time information, and a character or graphic indicating “level 1” is displayed as the initial value of the level information.

  Next, the level of the rotational driving force of the motor 51 is selected by the level selection key 21g, and the driving time (mixing process time) of the motor 51 is set by the time setting key 21e (step S22).

  Next, the control unit 10 determines whether the drive time set by the time setting key 21e is equal to or less than the maximum drive time according to the level selected by the level selection key 21g (step S23).

  When the drive time set by the time setting key 21e is equal to or less than the maximum drive time, the control unit 10 causes the display unit 22 to display the set drive time ("YES" in step S23 and step S24). . For example, when “20 minutes” is set by the time setting key 21 e and “level 3” is selected by the level selection key 21 g, the control unit 10 causes the display unit 22 to display “20 minutes”.

  On the other hand, when the drive time set by the time setting key 21e is larger than the maximum drive time, the control unit 10 causes the display unit 22 to display the maximum drive time ("NO" in step S23 and step S25). For example, as shown in FIG. 7B, when “20 minutes” is set by the time setting key 21e and “level 4” is further selected by the level selection key 21g, the control unit 10 displays the display unit 22. Display “15 minutes” on.

  Next, the control unit 10 limits the drive time of the heater 8 after resumption of drive which can be set with the time setting key 21e to a range equal to or less than the maximum drive time (step S26). Thus, for example, the state where the rotational driving force of the motor 51 is large continues for a long time, whereby the automatic bread making machine can be prevented from moving on the installation table by vibration and dropping from the installation table. .

  In the first embodiment, when “level 4” is selected by the level selection key 21 g and then the level is changed to “level 1”, the control unit 10 as shown in FIG. 7D. , “20 minutes” is displayed on the display unit 22. Thereby, in order to set to the maximum drive time (for example, 30 minutes) according to "level 1", the effort which increases drive time with the time setting key 21e can be reduced, and usability improves more. Can.

  Next, a control flow of the heater 8 by the control unit 10 when the baking process is selected by the process selection key 21 f will be described. FIG. 8 is a flowchart showing an example of a control flow of the heater 8 by the control unit 10 in the firing step and the post-burning step. FIGS. 9A to 9C are diagrams showing display examples displayed on the display unit 22 when the firing step or the post-baking step is selected by the step selection key 21 f.

  The control unit 10 is configured to perform a post-baking process of driving the heater 8 for an additional driving time set by the time setting key 21 e after the baking process is completed. In addition, the control unit 10 is configured not to perform the additional after-baking step when the number of after-baking steps exceeds the preset number. Furthermore, the control unit 10 sets an additional drive time (time for the post-baking process) that can be set by the time setting key 21 e within a range of a difference value between the maximum drive time and the total drive time of the heater 8 from the start of the baking process. Is configured to limit. In the first embodiment, the "maximum drive time" is preset for each heating power level selectable by the level selection key 21g. Here, when the level of the heating power of the heater 8 is “level 4”, the maximum driving time is 50 minutes.

  First, a firing process is selected by the process selection key 21f (step S31). Thereby, the character part of "baking" is lighted or blinks as process information in the display part 22. FIG.

  Next, the level of the heating power of the heater 8 is selected by the level selection key 21g, and the driving time (baking process time) of the heater 8 is set by the time setting key 21e (step S32). Here, as shown in FIG. 9A, “level 4” is selected by the level selection key 21g, and “40 minutes” is set by the time setting key 21e.

  Next, the start of the baking process is instructed by the start key 21b (step S33). Thus, the control unit 10 controls the driving of the heater 8 based on the temperature detected by the temperature sensor 9 to perform the firing process.

  Next, the control unit 10 determines whether the driving time set by the time setting key 21 e has elapsed (step S34).

Or, control is performed so that only "0 minutes" can be set. Also, for example, when “level 4” and “10 minutes” are set in the “B” step, the control unit 10 adds “5” in “level 4” in total in the “A” and “C” steps. Control so that only minutes can be set. According to this configuration, the automatic bread making machine moves on the installation table by vibration, for example, by the state in which the rotational driving force of the motor 51 is large continues for a long time without the user being particularly aware. It is possible to prevent something from falling out of

  Next, a control flow by the control unit 10 at the time of course selection of the kneading process will be described. FIG. 11 is a flowchart showing an example of a control flow by the control unit 10 at the time of course selection of the kneading process. 12A to 12G are diagrams showing display examples displayed on the display unit 22 when the course of the kneading step is selected.

  First, one course is selected from the courses of the plurality of kneading processes with the dough selection key 21h (step S41). Here, as shown in FIG. 12A, it is assumed that "P1" is selected as the course of the kneading process by the dough selection key 21h. Here, “P1” is a course corresponding to “Level 1” and “1 minute” in the “A” step, “Level 1” and “0 minute” in the “b” and “C” steps, and Do. When "P2" is selected as the course of the kneading process with the dough selection key 21h, "P2" is displayed on the course display unit 22a as shown in FIG. 12G.

  Next, the level of the rotational driving force of the motor 51 is selected (changed) by the level selection key 21g, and the drive time of the motor 51 is set (changed) by the time setting key 21e (step S42). For example, as shown in FIGS. 12B and 12C, after “level 2” is selected by the level selection key 21g in the “A” step, “7 minutes” is set by the time setting key 21e.

  Then, the start of the course is instructed by the start key 21b without selecting the next process by the process selection key 21f ("NO" at step S43 and step S44), the control unit 10 drives the motor 51. Control the course “P1”. At this time or later, in the storage unit, courses corresponding to "Level 2" and "7 minutes" in the "A" step, "Level 1" and "0 minutes" in the "b" and "C" steps. "P1" is overwritten as.

  For example, as shown in FIG. 12D, the "b" process is selected by the process selection key 21f, and as shown in FIG. 12E, the "level 1" is selected by the level selection key 21g in the "b" process. At the same time, "30 minutes" is set by the time setting key 21e. Further, for example, as shown in FIG. 12F, the “c” process is selected by the process selection key 21 f, and “0 minutes” is set by the time setting key 21 e in the “c” process.

  Thereafter, the start of the course is instructed with the start key 21b without selecting the next process with the process selection key 21f ("NO" in step S43, step S44), the control unit 10 drives the motor 51. Control the course “P1”. At this time or after this, the storage unit stores "Level 2" and "7 minutes" in the "A" process, "Level 1" and "30 minutes" in the "b" process, and "Level" in the "C" process. “P1” is overwritten as a course corresponding to “1” and “0 minutes”.

  At the start of the course of the kneading process, the kneading blade 7 is in a state in which the rotation is stopped. Therefore, the control unit 10 controls the motor 51 so as to generate a rotational driving force smaller than the rotational driving force according to the level 1, and rotates the kneading blade 7 at low speed for m seconds (for example, 30 seconds) Step S45). Thereby, the scattering of the cooking material such as the flour, water, and yeast in the kneading container 6 is suppressed.

  Thereafter, the control unit 10 temporarily uses the start key 21b during the total driving time set by the time setting key 21e (for example, "A" step: 7 minutes + "B" step: 30 minutes = 37 minutes). It is determined whether a stop instruction has been issued ("NO" in step S46 and step S47). When temporary stop is instructed by the start key 21b, the control unit 10 controls the motor 51 to stop to stop the rotation of the kneading blade 7 ("YES" in step S47 and step S48). During this temporary stop, for example, cooking materials such as wheat flour and water, and auxiliary materials such as raisins can be added to the kneading container 6.

  Thereafter, when restart is instructed by the start key 21b, the control unit 10 rotates the kneading blade 7 at low speed for m seconds (for example, 30 seconds) ("YES" in step S49 and returns to step S45). Thereby, the scattering of the cooking material such as the flour, water, and yeast in the kneading container 6 is suppressed.

  On the other hand, when a predetermined time (for example, 15 minutes) elapses without a restart instruction being given by the start key 21b, the course of the kneading process is ended ("YES" in step S50). The control unit 10 continues to stop the rotation of the motor 51 until a predetermined time (for example, 15 minutes) elapses ("NO" in step S50 and the process returns to step S48).

  If the total driving time set by the time setting key 21 e has not been instructed without a pause instruction by the start key 21 b, the control unit 10 ends the course of the kneading step (“YES” in step S 46) ).

  According to the automatic bread making machine of the second embodiment, the kneading step is divided into a plurality of steps, and the level of the rotational driving force of the motor 51 and the driving time of the motor 51 are set for each of the divided steps. It is configured to be possible. According to this configuration, for example, while the kneading blade 7 is rotated at high speed (or low speed) in the early stage of the kneading process, the kneading blade 7 can be rotated at low speed (or high speed) in the late stage of the kneading process. The hardness and texture can be further adjusted to suit the user's preference.

  Moreover, according to the automatic bread making machine according to the second embodiment, the courses of the plurality of kneading steps in which the combination of the level of the rotational driving force of the motor 51 and the driving time of the motor 51 is different for each of the divided steps. It has a storage unit for storing. Further, the process selection key 21 f is configured to be able to select one course out of the courses of the plurality of kneading processes stored in the storage unit.
