DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bread baking mold provided with a shaft rotatably driven by a motor and a kneading blade removably attached to the shaft on the bottom surface of the baking mold housed in the machine. The present invention relates to a kneading blade of a baking machine of a type in which kneading, fermenting and baking of bread ingredients are performed.

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open No. 1-62727.
As disclosed in Japanese Unexamined Patent Application Publication No. 2000-209, there is known an apparatus of a type that performs from bread dough making to dough fermentation and baking. In such a bread baking machine, the kneading wings are rotated in the bread baking mold to knead the bread ingredients, and then the fermentation
Firing. For this reason, the bread is baked while the kneading wings are buried in the bread dough, and when the baked bread is removed from the baking mold, the kneading wings come off together with the bread. Therefore, there was a trouble that the kneading wings had to be always removed from the baked bread, and there was also a danger of being burned by touching the freshly baked bread. In addition, there is also a disadvantage that the kneading wing is easily damaged or lost due to forgetting to remove it.

On the other hand, it is conceivable to physically prevent the kneading blade from coming off by, for example, tightening the fitting between the kneading blade and the shaft. However, if the bread material enters, there arises a problem that it becomes difficult to remove the kneading blade. Also,
As disclosed in Japanese Utility Model Laid-Open Publication No. 1-159541, there is known a shaft in which a concave groove is provided to prevent the kneading blade from coming off. However, such a configuration is effective in preventing the kneading blades from coming off during kneading, but cannot completely prevent the dough material from intruding between the shaft and the rotating blades. It was difficult to break the strong connection with the blades, the kneading blades came off together with the pan, and there was a problem that the blades and the shaft would stick if the rotating blades were not sufficiently cleaned after use.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to prevent the kneading blades from coming off together with the pan without obstructing the attachment / detachment of the kneading blades to / from the shaft. In this way, it is possible to prevent the cloth material from entering between them, thereby obtaining the original fitting relationship between them.

[0005]

According to the present invention, there is provided a kneading blade detachably mounted on a shaft, and a mounting hole penetrating vertically through the kneading blade is provided, and the kneading blade is mounted on the shaft. And, the upper edge of the mounting hole of the kneading blade is annularly recessed, and a lid plate is fitted into the recessed portion to deform the upper edge of the kneading blade to press the lid plate surface, thereby closing the mounting hole, The above-mentioned problems have been solved by coating these with a fluororesin.

[0006]

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 baker main body, 2 is a heating chamber formed in the main body 1 and opened and closed by a lid 3, and 4 is provided in the heating chamber 2 so as to be insertable and removable. It is a baked mold. A shaft 6 is provided on the bottom surface of the baking pan 4, and the kneading blades 5 are detachably attached to the shaft 6.

A motor 7 drives the kneading blade 5 to rotate.
Is a heater disposed in the heating chamber 2 so as to surround the baking mold, 9 is a temperature sensor for detecting the temperature of the baking mold 4,
10 is a control circuit for controlling the motor 7 and the heater 8;
Reference numeral 1 denotes an operation panel. The rotation of the motor 7 is controlled by the pulley 12
The shaft 15 is transmitted to the coupling 15 via the belt 13 and the coupling 15, and the shaft 16 is rotated by the coupling 16 which is paired with the coupling 15 to operate the kneading blade.

The control circuit 10 starts operating in response to an input on the operation panel 11 and drives the motor 7 to knead the bread material put in the baking pan 4, and then outputs a signal from the temperature sensor 9. The fermentation and baking of the dough is performed by controlling the power supply to the heater 8 while monitoring.

FIG. 2 is a partial sectional view of a main part of the embodiment, and FIG. 3 is a perspective explanatory view of the main part. One side of the peripheral surface is cut away from the center of the length of the shaft 6 protruding into the bread baking mold 4 toward the base side to form a D-shaped cross section, and the flat surface W has a lower side, that is, a base side higher than the upper side. It is formed so as to be inclined inward. The dimensions of the shaft 6 are set such that the tip of the shaft 6 is shorter than the length of the kneading blade 5 at the center so as to be fitted to the shaft 6.

An annular concave portion 18 is provided along the upper edge of the mounting hole 17 of the kneading blade 5, and a gap is formed between the upper end of the mounting hole 17 and the tip of the shaft 6. When the inner peripheral surface of the mounting hole 17 is fitted to the shaft 6, a projecting piece 20 smaller than the shaft diameter is formed at a position corresponding to the flat surface W, and the projecting piece 20 is fitted when the shaft 6 and the kneading blade 5 are fitted. In contact with the flat surface W, the rotating blade 5 is rotated with the rotation of the shaft 6. The rotary blades 5 have such a dimensional relationship that attachment and detachment to and from the shaft 6 are performed with some obstacles due to the contact between the projecting pieces 20 and the corners of the flat surface W. Reference numeral 21 denotes a cover plate, which is fitted into the recess 18 of the rotary blade 5 with a slightly lower height than the upper edge, and the fitted cover plate 21 faces the periphery of the recess 18 toward the peripheral surface of the cover plate 21. Deform the entire periphery or a plurality of locations. Then, at least the outer surface of the rotary blade 5 is treated with a fluororesin film to make the surface non-adhesive.

That is, the kneading blade 5 is attached to the shaft 6 such that the flat surface W and the projection 20 correspond to each other.
When an operation start input is made on the operation panel 11, the motor 7 is first rotated to knead the bread material. At this time, the bread material enters the space S so as to wind around the shaft. When the dough is kneaded in this manner, the dough is heated to an appropriate temperature by the heater 8 to ferment the dough. The fermentation is repeated while the gas is released by driving the motor 7 as needed, and when the fermentation is completed, the heater 8 is energized with a high load to bake the bread.
Has no openings on the top and side surfaces, so that the dough material does not penetrate into the interior and is made non-adhesive so that the dough material can be kneaded without clinging. Of the flat surface W does not come off easily by contact with the corners of the flat surface W, so that the blades can be taken out without leaving the blades in the bread.

[0012]

According to the present invention, the kneading blade is not provided with an unnecessary opening so that the dough material does not enter between the kneading blade and the shaft, and the surface of the blade is made non-adhesive. Since the bread material does not enter the space between the blade and the shaft, and the dough material does not adhere to the blade, the effect can be further improved. Also, since the blade and the shaft form a fitting relationship with the flat surface and the projection, they are fitted with an appropriate play relationship, and by being inclined in a flat surface reverse taper shape,
The kneading blades do not come off even when the bread is taken out, as it has an upward retaining function. In addition, it is not necessary to particularly strengthen the connection with the shaft when the kneading blades are mounted, and there is no sacrifice in attaching / detaching the kneading blades to / from the shaft.
