BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a bread baking mold in which a shaft rotated by a motor and a kneading blade detachably attached to the shaft are provided on the bottom surface of the baking pan housed in the machine. The present invention relates to a bread-baking machine of a type for kneading, fermenting and baking bread ingredients.

2. Description of the Related Art Conventionally, for example, actual Kaihei 1-62727.
As can be seen in Japanese Patent Publication, there is known an apparatus of a type that performs from making bread dough to fermenting and baking the dough. In such a bread baking machine, the kneading blades are rotated in the bread baking mold to knead the bread ingredients, and then the fermentation and
It is firing. For this reason, the bread is baked with the kneading blade buried in the bread dough, and when the baked bread is taken out of the baking mold, the kneading blade comes off together with the bread. Therefore, the kneading blades must always be removed from the baked bread, and there is a risk of burns from touching the freshly baked bread. In addition, there is a disadvantage that the kneading blade is easily damaged or lost by forgetting to remove it.

On the other hand, it is possible to physically prevent the kneading blade from coming off by a method such as tight fitting between the kneading blade and the shaft. However, when the bread ingredients enter, there is a problem that it becomes difficult to remove the kneading blade. Further, as disclosed in Japanese Utility Model Laid-Open No. 1-155941, there is known a shaft provided with a groove to prevent the kneading blade from coming off. However, with such a configuration, even if it is effective in preventing the kneading blades from coming off during kneading, it is difficult to break the strong bond between the baked bread and the kneading blades, and the kneading blades may come off together with the bread. There were many

[0004]

Therefore, the object of the present invention is to prevent the kneading blade from coming off together with the bread without inhibiting the attachment and detachment of the kneading blade to the shaft. .

[0005]

According to the present invention, a kneading blade is provided with a mounting hole that penetrates vertically to mount the kneading blade on a shaft, and the upper edge of the mounting hole of the kneading blade is recessed to form the shaft. In order to solve the above-mentioned problems, a space for entering the bread material is formed between the peripheral wall and the peripheral wall of the shaft, and a horizontal groove is provided on the peripheral wall of the shaft located at or above the concave position. is there.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional explanatory view showing the configuration of the embodiment, 1 is a bread baking machine main body, 2 is a heating chamber formed in the main body 1 and opened / closed by a lid 3, and 4 is provided in the heating chamber 2 so as to be detachable. It is a bread baking type. A shaft 6 is provided on the bottom surface of the bread baking mold 4, and the kneading blade 5 is detachably attached to the shaft 6.

Reference numeral 7 is a motor for driving the kneading blade 5 to rotate, 8 is a heater arranged in the heating chamber 2 so as to surround the bread baking mold, 9 is a temperature sensor for detecting the temperature of the bread baking mold 4, 1
0 is a control circuit for controlling the motor 7 and the heater 8, 11
Is an operation panel. The rotation of the motor 7 is performed by the pulley 12.1.
3 and the belt 14 and is transmitted to the coupling 15, and the shaft 16 is coupled by the coupling 16 which is paired therewith.
To rotate the kneading blade.

The control circuit 10 starts its operation in response to an input on the operation panel 11, drives the motor 7 to knead the bread ingredients put in the bread baking mold 4, and then outputs a signal from the temperature sensor 9. The heater 8 is energized while being monitored to ferment and bake the bread dough.

FIG. 2 is a partial sectional view of the essential part of the embodiment, and FIG. 3 is a perspective explanatory view of the essential part. The tip of the shaft 6 protruding into the baking pan 4 is cut out at one side to have a D-shaped cross section.
The kneading blade 5 having the holes 7 is loosely fitted therein. The mounting hole 17 penetrates vertically and is dimensioned so that the shaft 6 projects above the mounting hole 17 in the mounted state as seen in FIG.

A concave portion 18 is provided along the upper edge of the mounting hole 17 of the kneading blade 5, and an arc-shaped gap is formed between the upper end of the mounting hole 17 and the shaft 6. Above the recessed portion 13 of the shaft 6, a horizontal recessed groove 20 is provided on a peripheral wall forming an arc excluding the cutout portion 19. This allows
Between the kneading blade 5 and the shaft 6, there is formed a bread material entry space S including a concave horizontal surface 18a on the kneading blade 5 side and a downward groove downward horizontal surface 20a on the shaft 6 side. The bread ingredients thus prepared function as retaining stoppers for the kneading blades 5.

That is, when the bread ingredients are put into the bread baking mold 4 and an operation start input is made on the operation panel 11, the motor 7 is first rotated to knead the bread ingredients. At this time, the bread material enters the space S so as to be wrapped around the shaft. When the bread dough is kneaded in this way, it is heated to an appropriate temperature by the heater 8 to ferment the bread dough. On the way, the motor 7 is appropriately driven to repeat the fermentation while degassing,
When the fermentation is completed, the heater 8 is energized with a high load to bake the bread. Here, the bread material that has entered the space S is also baked and hardened between the kneading blade 5 and the shaft 6 between the flat surfaces 18a and 20a. Therefore, even if the baked bread is taken out from the bread baking mold, the bread material hardened in the space S prevents the kneading blades 5 from remaining on the shaft 6.

[0012]

[Effect of the Invention] This invention is configured as described above, and since the space through which the bread material can enter is formed between the kneading blade and the peripheral wall of the shaft, the bread material that enters this space is accompanied by baking of the bread. It hardens to prevent it from coming off, and the kneading blade does not come off when the bread is taken out. Further, it is not necessary to specially strengthen the connection with the shaft when the kneading blade is mounted, and the attachment and detachment of the kneading blade with respect to the shaft is not sacrificed at all.
