[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bread maker for producing bread by subjecting materials put into a bread baking mold to kneading, fermenting and baking steps in a general household.

[0002]

2. Description of the Related Art Conventionally, when making bread in a general household, the equipment has been used in accordance with each process. Has been developed. This type of apparatus manufactures bread while shifting over a basic sequence consisting of a kneading step of kneading the ingredients, a fermentation step of fermenting the kneaded dough, a baking step of baking the bread by energizing a heater, and each step. .

[0003] In making bread, it is important to control the temperature of yeast cells in order to provide high-quality bread regardless of summer or winter.
It is known that an alarm is issued without starting the operation when the temperature is close to a temperature (yeast germ temperature) that is not suitable for the activity of yeast before the start of the bread making operation as in No. 7.

[0004]

By the way, when it is determined that the bread making operation cannot be performed due to such temperature detection, it is possible to recognize only the cause that the temperature is too high, but at what temperature it cannot be performed. I couldn't understand at all how it would be an environment where a baking operation could be performed. In addition, even if the temperature condition returns to the one suitable for bread making, there is no function to positively notify that, so each time the user inputs a start and checks whether the bread making operation is possible. I had to.

[0005] Further, in the case of making bread continuously after baking, since the inside of the baking case is in an extremely high temperature state, the yeast in the material is killed as soon as the baking mold is set. There was a problem that it would. That is, in such a case, it is necessary to notify that the temperature in the baking case is high before setting the baking mold in the baking case.

Therefore, the present invention firstly makes it possible to easily recognize the reason why the baking operation cannot be started and how to cope with it, and to immediately understand that the temperature has returned to a temperature suitable for baking. The purpose is to provide a machine. Secondly, it is another object of the present invention to provide a bread maker in which a baking mold in which a bread material is put is prevented from being put in a baking case in a high temperature state.

[0007]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention firstly provides a bread baking mold having a kneading blade at an inner bottom, and a baking mold inserted and removed along an inner wall surface.

When the determination unit determines that the start command of the bread making operation is invalid, a notification unit that provides guidance on the content and a countermeasure, and a temperature detection unit that continues even after the determination unit determines whether the start is possible. Then, when the temperature is changed to an appropriate temperature, a control means is provided for notifying the notification by the notification means.

Secondly, a baking pan having kneading blades at the inner bottom, a baking case in which the baking die is inserted and removed, and a heater attached along the inner wall surface, and a temperature in the baking case, Temperature detecting means for detecting, input means for starting a baking operation and selecting a plurality of baking courses to be detected, and detecting by the temperature detecting means during a period from power-on to start input by the input means. Determining means for determining whether or not the temperature inside the firing case is higher than or equal to a predetermined temperature; and when the determining means determines that the temperature inside the firing case is high, a notification for guiding the content and a coping method. Means and the temperature detecting means continuously performs temperature detection even after the start means is judged by the judging means, and when the temperature has changed to an appropriate temperature, the notifying means notifies the effect and cannot be executed. It was provided with a control means for disabling the selection of the bread course.

[0009]

According to the present invention, first, when the input from the input means for starting the bread making operation is invalidated, the cause and the countermeasure are guided by the notifying means, and the temperature returns to the appropriate temperature. In such a case, the notification means notifies the fact. Secondly, if the temperature detected at the time of turning on the power is too high, a course that cannot be executed among a plurality of bread making courses cannot be selected, and yeast cells are put into the baking case in a high temperature state.

The display panel 8 is a liquid crystal display (LCD)
A screen for selecting a bread-making course, a screen for showing the cause of various errors and how to deal with them, a screen for showing the bread-making process being executed, and the like are displayed. A transparent touch switch 20 is attached to the surface of the display panel 8 so that input can be switched between valid and invalid according to the screen displayed on the display panel 8.

FIG. 4 is a flowchart showing the operation of the bread maker of the present invention, and FIG. 5 is an explanatory diagram showing various screens displayed on the display panel 8 and an operation method on the screens. When the power is turned on, first, the temperature T1 in the firing case 3 is set.
Is detected (1), and it is determined whether or not this temperature T1 is lower than or equal to the yeast killing temperature Ta (2). Note that Ta is set at around 60 ° C.

If T1 is lower than Ta, a screen (a) for selecting a bread-making course is displayed on the display panel 8 (3), and a state of waiting for the selection of a bread-making course (4). When a part on which a desired course is displayed is pressed on the display panel 8 (here, “white bread” is selected), a screen for performing various settings in the pressed course (b)
(5), the bread size (1.5 loaves or 2 loaves, etc.) and the roasted shade are set. In this screen (b), the type and quantity of bread ingredients necessary for the selected course and the nutrients contained in the bread can be displayed, and the bread necessary for the bread case 9 is checked while confirming on the display panel. Material can be set.

The bread case 9 into which the bread ingredients are put is set in the baking case 3, and when "start" is inputted from the screen (b) (6), the temperature T in the baking case 3 at that time is input.
2 is detected (7), and it is determined whether or not this temperature T2 is within a temperature range (Tb <T2 <Tc) suitable for the activity of yeast (8). Here, Tb is set at around 20 ° C., and Tc is set at around 40 ° C.

Here, if T2 is between Tb and Tc,
The screen is switched to a screen (c) that displays the selected course, various settings, the completion time of baking, and the process being executed (9), and the baking machine executes the kneading process, and thereafter performs the fermentation, degassing, forming, and baking. The baking operation for sequentially performing the steps is started (10), and when the baking operation is completed (11), the process returns to the process (1) for detecting the temperature T1 in the baking case 3 again.

If T1 is higher than Ta in the judgment of the process (2), the buzzer 18 sounds (12) and the screen (d) is displayed on the display panel 8 (13). On the screen (d), it is notified that the yeast may be killed because the inside of the baking case 3 is at an extremely high temperature, and the temperature in the baking case 3, a method of coping with an error, and a baking course which can be selected in this state. (Here, “jam” and “add grill”) are displayed.

If a "jam" or "add baking" course which can be selected on this screen (d) is selected (14), the display panel 8 is displayed on a screen (b) (15), and when a start is inputted, (16) The process shifts to the process (9) to execute the course sequence. When the course is not selected, the temperature T1 in the firing case 3 is continuously monitored (17), and when the temperature falls below Ta (18), the buzzer 18 notifies the user (19), and the display panel 8 displays the screen ( The display of a) is displayed, and the process returns to the process after the process (3).

If T2 is lower than Tb in the judgment of the process (8), the buzzer sounds (20) and the screen (e) is displayed on the display panel 8 (21). On the screen (e), the fact that the inside of the baking case 3 is low in temperature is not suitable for the activity of yeast and that good bread dough cannot be produced, and the temperature in the baking case 3 and a method of coping with an error are displayed. You.

When the temperature is low, a preheating step is provided in order to bring the inside of the firing case to an appropriate temperature in a short time. When "preheating" is pressed on the screen (e) (22), the heater 13 is energized ( 23). Thereafter, the temperature T2 in the firing case 3 is continuously monitored (24), and if T2 becomes higher than Tb (2)
5), the buzzer 18 notifies the user (26), and the display panel 8 displays the screen (b), and the processing after the processing (5) is executed.

If T2 is higher than Tc in the determination of the process (8), the processes after the process (20) are performed in the same manner as in the case of the low temperature described above, except that the contents displayed on the screen (e) and the preheating step are not performed. Are performed, so that separate description and illustration are omitted.

When a "timer" is input from the screen (a), a reserved bread making screen (f) for setting the baking completion time
Switch to In this screen (f), for example, when setting for baking bread at 7:00 in the morning, a method of inputting a time obtained by subtracting a time to bake from the current time or a method of directly inputting a time to bake can be considered. The latter method, which is easier to operate, is adopted, and the time is scrolled using the up and down keys to adjust to the desired completion time. When "start" is input, the screen changes to a screen (c), and the timer process is started.

Also, at the time of the start input here, the judgment of the processes (7) and (8) is executed. At this time, the temperatures Tb and Tc to be determined are set differently from the case where the direct kneading step is performed without executing the timer step. Here, the low set temperature Tb disappears when the timer is set,
The high set temperature Tc is set around 45 ° C. When the temperature is low, the temperature at the start of kneading can be kept constant because the temperature control for keeping the inside of the firing case 3 at a constant temperature during the timer process is performed in the preheating process. This is because yeast fermentation does not progress before the ingredients are mixed, and the possibility of over-fermentation is low. In addition, each set temperature is not limited to the above embodiment.

As described above, in this embodiment, the temperature is detected twice when the power is turned on and when the start is input. The check at power-on prevents accidental placement of yeast in the baking case that is in an ultra-high temperature state immediately after baking, and the check at the start input makes the yeast in an environment that does not match the yeast activity. It limits pan start. For these temperature managements, only one of the checks may be performed by changing the set temperature. In addition to notifying the occurrence of these errors with a buzzer, notifying how the errors can be resolved on the display panel and what the temperature in the firing case is, it is possible to take prompt action, In some cases, a method of cooling or heating the inside of the firing case using a drier or the like can be adopted. It should be noted that the notification means may be of course by voice.

[0025]

The present invention is configured as described above.
Regardless of the difference in environment such as summer and winter, bread can always be made in good condition, and bread making with few failures can be performed. Also, when the error is resolved and the baking case is in good condition, it will be notified so that you can move on to baking quickly,
In addition, it is possible to recognize what kind of error state the baking case is in, and to report the coping method at the same time, so that it is possible to cope with the error positively and move on to bread making earlier.
