Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household automatic bread maker having a weighting sensor, which has a bundling step, a kneading step and a baking step.

[0002]

2. Description of the Related Art As a conventional automatic bread maker, a weight sensor is provided as disclosed in Japanese Patent Laid-Open No. 2-181616, but the detected weight is not reflected in the bread making sequence but is displayed. is there. Further, as a high-frequency heating cooker having a bread making function, for example, Japanese Patent Laid-Open No. 1-1
As disclosed in Japanese Patent No. 71516, in a kneading blade capable of high-speed rotation by kneading blades during kneading and low-speed rotation by a turntable during high-frequency heating, a weight sensor is provided below a driving main shaft, and high-frequency heating is performed based on the detected value. There is one that can obtain a stable rotation speed even if the weight changes at low speed rotation.

In the conventional automatic bread maker, the sequence of the automatic bread maker shown in FIG. 4 and FIG. The same sequence was used for both 1.5 and 2 loaves, and the sequence corresponding to the bread capacity of the bread dough was not changed. Therefore, since the process time and the main motor energization rate do not match the bread capacity of the bread dough, the dough cannot be collected in the dough combining process, and powder and sub-materials in the container are scattered and spilled from the container in the next kneading process. There were problems that the interior of the room was soiled, that kneading was insufficient, or conversely, that the material was too kneaded, and that the bread was burned in the subsequent baking process.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a container that is detachably mounted in a heating chamber and is attached to the outside of the container in the heating chamber. An automatic bread maker having a heater, a main motor mounted outside the heating chamber, and a control unit for controlling the main motor, the heater, etc. A weight sensor that detects the weight of the container is installed in the control unit, and the control unit detects the weight of the container based on the output of the weight sensor and determines the pan capacity of the material in the container based on this weight. The duty ratio is controlled.

Specifically, the controller controls the energization ratio of the main motor depending on the weight of the material in the container when the bread capacity is equivalent to 1 loaf to 1.5 lobes in the gathering step for gathering the powders before entering the kneading step. 10%, and if it is equivalent to 2 loaves, increase the energization rate of the main motor to 30%, and further increase the process time from 1 minute to 3 minutes.
The dough is put together by increasing the amount to about 20 minutes when the bread volume is equivalent to one loaf, approximately 25 minutes when 1.5 lobbies are equivalent, and approximately 27 minutes when 2 lobbies is equivalent to the bread volume in the kneading step. Assuming that the time is changed, the weight reduction rate of the initial material is calculated based on the weight of the material in the baking process, and the weight reduction rate of the initial material is calculated (for example, 12% reduction). I decided to bake it.

With this structure, the control unit determines the amount of bread dough based on the output of the weight sensor, and automatically determines the amount of bread dough according to the capacity of the bread, such as the combining process, the kneading process, the fermentation process, and the baking process. Select a sequence, suppress the scattering of powder when bundling the bread dough, and knead it thoroughly.
Control to bake delicious bread that is not raw or overbaked.

As described above, according to the present invention, in an automatic bread maker that automatically performs food processing such as bread making, a weight sensor for detecting the weight of the container is provided, and the control unit outputs the weight sensor to the container. The weight of the container is detected and the pan capacity of the material in the container is judged based on this weight to control the sequence process time and the main motor energization rate. In the process, if the pan capacity is equivalent to 1 loaf to 1.5 lobes, the duty factor of the main motor is 10%, and if it is equivalent to 2 loaves, the duty ratio of the main motor is increased to 30%, and the process time is from 1 minute to 3 minutes. Since the dough is put together by increasing the amount to the minutes, it is possible to suppress the scattering of the materials in the container in the kneading process, and in the kneading process, if the bread capacity is equivalent to 1 loaf, it is 20 minutes,
Since the time required for kneading is changed according to the bread capacity, it is 25 minutes for 1.5 lobbies and 27 minutes for 2 lobbies, so that it is possible to eliminate over-kneading or insufficient kneading of the dough,
In the baking process, the weight at the time of baking is calculated based on the weight of the material, and it is decided to bake until the weight of the initial material is reduced by 12%, so it is possible to bake delicious bread without raw baking or overbaking. There is an effect that a bread maker can be provided.
