Although not shown in the figure, a notch for disengaging the engagement with the protrusion 27 is formed therein.

A rotating shaft 28 is inserted into the molding box 13. That is, in this example, a through hole is formed in the center of the fixture 25, a bearing 29 is attached to the inner peripheral surface of this through hole, and the rotating shaft 28 is inserted into the bearing 29 so as to be rotatable. In addition, the bottom plate 13b of the molding box 13 and the mounting base 26
Through holes are formed in the molding box 13, and the rotating shaft 28 can be positioned inside the molding box 13 by passing through these through holes. A rotating spatula 31 is attached to a rotating shaft 28 within this molding box 13 . The rotating spatula 31 has one end 31a shaped like a cap, and the inner end of the rotating shaft 28 is vertically and detachably inserted into the cap-shaped portion 31a. A detent key 33 formed on the outer periphery and fitted into this groove 32 is formed to protrude from the inner peripheral surface of the cap portion 31a, so that the cap-shaped portion 31a can be placed over the shaft 28 from the upper end of the rotating shaft 28. The rotating spatulas 31 , which are mutually engaged in the direction of rotation and thus perpendicular to the rotating shaft 28 , rotate when the rotating shaft 28 rotates.

A fixed spatula 34 is provided close to the rotation circle of the rotating spatula 31 and extending in the radial direction of the rotation circle.
For example, as shown in this figure, the rotating shaft 28 has a cylindrical shape, and the fixed shaft 35 is inserted into the rotating shaft 28. The lower end of the fixed shaft 35 is fixed to the bottom plate 11a of the case 11, and the upper end of the fixed shaft 35 penetrates the rotating shaft 28 and the cap-shaped part 31a of the rotary spatula, and projects into the molding box 13, and the upper end of the fixed shaft 35 is fixed to the bottom plate 11a of the case 11.

A belt 53 is placed between the pulley 43 and the pulley 43, and the rotation of the shaft 48 is transmitted to the pulley 43 through the belt 53 at a reduced speed.

Further, in this embodiment, means are provided for detecting the temperature of the material while it is being kneaded. In this example, as shown in FIG. 2, the fixed shaft 35 is formed with a center hole 54 that communicates in the axial direction, and the inner end of the center hole 54 is located near the inner end of the fixed shaft 35, that is, in a cap-shaped portion. 31a and 34a, and a temperature-sensitive resistance element 55 is inserted at that position.
A lead wire 56 of the temperature-sensitive resistance element 55 is led out from the lower end of the fixed shaft 35. As shown in FIG. 1, a heater 57 is placed around the outer periphery of the molding box 13 for heating the material inside the molding box 13 to bake bread. The panel board 58 of the box 11 has a power switch 59, a bread completion time setting button 61,

A temperature-sensitive resistance element 65 is provided near the outer periphery of the molding box 13 in order to control the temperature during heating.

To automatically bake bread in this configuration, use lid 1.
2, then remove the top lid 13a of the molding box, put a predetermined amount of ingredients such as flour, yeast, butter, sugar, etc. into the molding box 13, close the lids 13a and 12, and put a predetermined amount into the water tank 14. All you have to do is add water, put ice 18 in the ice case 17, set the bread completion time, and turn on the power. In this way, the water in the water tank 14 is maintained at a temperature of about 5° C. even in summer, and remains at a constant temperature regardless of whether it is summer or winter. About 4 hours before the set bread completion time, the pump 21 is activated to supply the water in the water tank 14 into the molding box 13, and the motor 44 is driven to rotate the rotary spatula 31. For example, it is said to be about 200 times per minute. This rotation kneads the material in the forming box 13, but at this time, the material gets entangled with the fixed spatula 34, and this and the rotating spatula 3
1, the material can be kneaded sufficiently even at a relatively slow rotational speed.
During the initial kneading, the temperature of the material is approximately 15°C, but during kneading the temperature of the material rises, and this temperature is sensed by the temperature-sensitive resistance element 55. When the temperature reaches a predetermined temperature, for example 27°C, it is determined that the dough has been sufficiently kneaded and the kneading process is finished. At this time, as mentioned earlier, the temperature of the supplied water is a constant temperature of, for example, 5℃, the initial kneading temperature always starts from about 15℃, and the kneading time is only about 10 minutes. Because of this, it is almost unaffected by temperature fluctuations and is always kneaded in good condition, resulting in glossy and delicious bread dough. When this kneading process is completed, primary fermentation gas venting, secondary fermentation gas venting, molding fermentation, etc. are automatically performed by the control unit (not shown in the figure), and then the heater 57 is energized and the molding box 13 The inside is heated, the ingredients inside are baked, and the bread is baked by heating for a predetermined period of time.

In addition, as shown in FIG. 2, the upper lid 13 of the molding box 13
The hole 23 a is formed in the center of the recess 66, and there is no need for strict alignment when supplying water from the water tank 14 to the molding box 13. In addition, by appropriately selecting the size of this hole 23, the moisture that has filled the molding box 13 can escape through the hole 23, and the surface of the kneaded bread material during fermentation can be prevented from condensation. Good bread baking is possible by keeping the humidity constant.

As mentioned above, knead the material in the molding box 13,
In order to bake bread by heating the molding box 13 of the kneaded material, spatulas 31 and 34 for kneading the material are arranged inside the molding box 13, and since the bread is baked with these spatulas, the baked bread is If the bread gets stuck on the bottom plate or side plate of the molding box 13, it becomes difficult to take out the bread from the molding box 13.

FIG. 3 shows an example of a molding box for an automatic bread maker according to this invention. The molding box 13 has a substantially rectangular parallelepiped shape, and has six constituent plates, namely an upper constituent plate 13a constituting an upper lid, and a bottom constituent plate 13a constituting a bottom surface.
