Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an automatic bread making machine that automatically produces bread by kneading, fermenting and baking bread dough.

Conventional technology Conventional bread making machines of this type are
As shown in Publication No. 75047, bread is baked automatically, and as shown in FIG. In some devices, the microcomputer circuit 10 controls the current supply to the heating member 13 based on the set temperature during kneading and fermentation based on the input result. However, this set temperature was set at a constant temperature around 30°C regardless of changes in room temperature.

Problems to be solved by the invention Therefore, according to the above structure and process, when the room temperature is low, the internal temperature of the bread dough 11a in the bread container 11 is such that heat is removed from the bottom of the bread container 11 near the heating member 13. The temperature sensing element 1 installed on the outside of the bottom of the bread container 11 is used to maintain a low temperature.
Assuming that the set temperature of bread dough 1 is the same as when the room temperature is not low, the temperature of bread dough 11a is the same as when the room temperature is not low.
There was a drawback that the temperature was lower than the target temperature during kneading and fermentation of 1a.

In addition, when the room temperature is high, the temperature outside the bottom of the bread container 11 is lowered for some reason by washing the bread container 11 with water or using cold water for the material water. There was a drawback that the element 12 erroneously detected the temperature of the bread dough 11a and controlled the energization of the heating member 13, causing the temperature of the bread dough 11a to be higher than the target temperature during kneading and fermentation.

Means for Solving the Problems The present invention was made to eliminate the above-mentioned drawbacks, and it inputs the detection results of a temperature sensing element installed at the bottom of the container to detect the temperature of the dough, and and a computer circuit having a selection function of selecting a plurality of set temperatures suitable for the room temperature, and a heating member that performs energization control suitable for the room temperature and the set temperature via this circuit while detecting the temperature of the dough. It is something.

By doing the above, the temperature of the bread dough during kneading and fermentation can be increased when the room temperature is low, thereby preventing insufficient fermentation, and when the room temperature is high, the temperature of the bread dough can be lowered and kneaded. Prevent over-fermentation.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view of this embodiment. A bread container 3 having a kneading blade 2 at the bottom is provided inside the main body 1, and the kneading blade 2 is rotated by a drive motor 4 to knead the bread dough 3a in the bread container 3. A temperature sensing element 5 is provided outside the bottom of the bread container 3.
The microcomputer circuit 6 controls the supply of electricity to the heating member 7 while detecting the temperature of the bread dough 3a based on the input from the microcomputer circuit 6, and the heating of the heating member 7 controls the temperature during kneading and fermentation of the bread dough 3a. It's getting old.

FIG. 2 is a process diagram according to this embodiment. The microcomputer circuit 6 operates at a room temperature RT ₁ at a high temperature of 30°C or higher, a room temperature RT ₂ at a normal temperature of 15 to 30°C,
It is divided into three types: room temperature RT ₃ , which is a low temperature of 15℃ or less. A function to select one of each room temperature, and a set room temperature of 28℃ in the microcomputer circuit 6 according to each selected room temperature RT ₁ , RT ₂ , RT ₃
t ₃ , a set room temperature t ₂ of 30°C, and a set room temperature t ₁ of 32°C.

Next, the operation of this embodiment consisting of the above configuration and steps will be explained.

First, when ingredients for the bread dough 3a are put into the bread container 3 and a power source (not shown) is turned on, the kneading blades 2 are rotated by the drive motor 4 and kneading is performed.

After kneading, the microcomputer circuit 6
The drive motor 4 is automatically stopped (detailed explanation is omitted) and the fermentation process is started.

During this kneading and fermentation, when the room temperature is low RT ₃ , the microcomputer circuit 6 is set at the set temperature t ₁
and make it high. Therefore, the bread dough 3a in the bread container 3
Since the temperature is increased by the amount of heat removed to the outside air, there is no possibility of insufficient gluten production due to insufficient kneading or insufficient fermentation.

On the other hand, in the case of a high room temperature _RT1 , the microcomputer circuit 6 lowers the set temperature to _t3 . Therefore, even if the bread container 3 is cooled by washing or cooling with cold water, the heating member 7 may malfunction and raise the temperature of the bread dough 3a above the target level, which may worsen the production of gluten due to over-kneading or cause overfermentation. It won't happen.

Effects of the invention As described above, according to the invention, while the temperature of the dough is detected by the thermosensor, the microcomputer circuit sets the temperature higher when the room temperature is low, and lower when the room temperature is high. By setting this setting, you can avoid problems such as insufficient kneading during kneading, resulting in hard bread, over-kneading, resulting in soft bread, insufficient fermentation during fermentation, which causes poor rise, and over-fermentation, which causes bread to shrink quickly after baking. The automatic baking method is extremely effective in making bread, and the finished bread can be made into large, delicious breads with a certain degree of firmness and chewiness at the same temperature as at normal temperatures. We can provide bread machines.
