Further, the upper part of the heating tank 6 is covered with a lid body 12,
Moreover, the temperature sensor 13 is fixed to the outer surface of the heating tank 6. 14 is a timer, a temperature control circuit, and a power control circuit. With this configuration, when the ingredients are put into the kneading container 8 and the timer is set, the operation starts at the predetermined time, and each step is automatically performed by the timer and temperature adjustment, and the bread is baked at the predetermined time. It is something.

Problem to be Solved by the Invention In an apparatus that automatically performs fermentation and baking in the same container from the dotted line 9, if a sealing material 16 as shown in FIG. 6 is used in the conventional configuration, Due to the pressure of the material, the material may penetrate into the interior of the sealing material 16, and in the worst case, may penetrate into the bearing 15, causing the shaft 9 and the bearing 15 to stick together, or causing seizure. There was a problem.

Additionally, if baking is performed in the same container, the bread will stick to the area around the sealing material 16 (particularly the shaft 9), and if kneading is continued in that state, the movement of the shaft 9 in the thrust direction will cause the baked bread to stick. There was also the problem that a portion of the sealing material 16 entered the interior of the sealing material 16.

The present invention has been made in view of these problems, and by providing an additional seal structure on the upper end surface of the sealing material, it is possible to further improve reliability against material intrusion into the interior of the sealing material. The purpose is to provide an automatic bread making machine that can.
