In order to solve these problems, an automatic bread maker having a configuration in which the kneading function, the fermentation function, and the oven function shown in FIG.

In the structure shown in FIG. 3, a frame 2 is provided inside a main body 1, a motor 3 is fixed to the frame 2, a heating tank 6 equipped with a heater 4 and a heat insulating material 5 is fixed, and heating is performed. Kneading container 8 having kneading blades 7 in tank 6.
Is detachably attached, and the kneading blade 7 is decelerated by the belt 9 and the pulley 10. Further, the upper part of the heating tank 6 is covered with the lid 11, and the temperature sensor 12 serves as the heating tank 6.
It is fixed to the outer surface of. 13 is a timer, temperature control,
It is a circuit for power adjustment. When the ingredients are put into the kneading container 8 with such a configuration and the timer is set, the operation starts at a predetermined time, each process is automatically performed by the timer and temperature adjustment, and the bread is baked after the predetermined time has elapsed. Further, the kneading step is performed at the same time as the start of the operation, the motor is continuously rotated for a certain time, and the kneading blade 7 is rotated,
It is controlled so as to knead the introduced materials.

Problems to be Solved by the Invention In such a conventional configuration, when materials such as wheat flour and water are put into a kneading container and a kneading blade is rotated, at first, the water and the powder are not mixed yet. , The flour-like portion and the dango-like portion of the flour that has become muddy by absorbing some amount of moisture are formed as a whole, and the dango-like portion is largely gathered together, but is moved by the centrifugal force to the outside. The whole dough is rolled up as a whole. The dough is then kneaded, compressed, or pulled between the kneading blades and the inner wall of the kneading container to knead the dough together. At this time, if the number of rotations of the blade is too low, kneading cannot be sufficiently performed and the bread dough cannot be in a good state, so a certain number of rotations is required. However, if it is continuously rotated at the required number of rotations from the beginning of kneading, the powder and the wheat flour which has become a little dango-like are liable to be scattered to the outside by the centrifugal force of the blades and further scattered to the outside of the kneading container. . Therefore, there is a problem that the inside of the baking chamber becomes dirty, and further, it is burned, which makes it difficult to remove the dirt.

It is an object of the present invention to provide an automatic bread maker that solves such problems.

Means for Solving the Problems In order to achieve the above object, the present invention provides a firing chamber having a heater, a kneading container detachably mounted in the firing chamber, and a motor mounted on the inner bottom of the kneading container.

It is designed to rotate continuously.

Action According to the above configuration, since the kneading blade does not continuously rotate at the start of kneading, the centrifugal force thereof does not cause the powder or the like to be scattered to the outside of the kneading container. It can be made into a single dango shape, and even if it is continuously rotated from this state, powder etc. have already disappeared, so there is no worry of jumping out of the kneading container, and the bread dough should be kneaded strongly with a kneading blade. Is something that can be done.
