Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bread making machine that is characterized by kneading bread ingredients.

BACKGROUND OF THE INVENTION Bread making machines currently on the market have a kneading structure as shown in FIGS. 6 to 8. In the one shown in FIG. 6, a kneading blade 3 is provided which can be detachably attached to a rotary shaft 2 protruding from the inner bottom of a kneading container 1. The one shown in FIG. 7 has a kneading rod 4 protruding from the side of the kneading container 1 in addition to the structure shown in FIG. The one in FIG. 8 includes a boss part 5 that can be detachably attached to a rotating shaft 2 protruding from the inner bottom of the kneading container 1, and a rotating shaft 6 provided on the boss part 5 that can be rotated in the direction of rotation of the rotating shaft. It has wing portions 7 that rise and fall.

Problems to be Solved by the Invention Usually, automatic bread making machines are often used at night, and therefore, the biggest challenge has been to reduce the noise during kneading.

For this purpose, it was essential to lower the rotation of the kneading machine during kneading.

However, in order to strongly knead the dough, the kneading blade 3 shown in Fig. 6 needs to have a high rotational speed or a large area. There was a problem in that the height of the blades 3 was too large and a large residue of the kneading blades remained in the baked bread. In addition, as shown in Fig. 7, if a kneading rod 4 is provided that protrudes from the inner surface of the kneading container 1, even if the kneading blades are small, the rotation speed will be low (but the dough will be kneaded strongly between the kneading rod 4 and the kneading rod 4). You can, but
Since the kneading rod 4 protrudes from the inner surface of the kneading container 1, there is a problem in that when the bread is baked, the bread cannot be taken out unless the kneading rod 4 is removed. In addition, the one shown in Fig. 8 has a configuration in which the wing portion 7 rises and falls depending on the direction of rotation of the rotating shaft 2, so that it stands up when kneading the dough (indicated by the dotted line), and lies down (indicated by the solid line) after kneading the dough. During kneading, the large-area wing section 7 is used to knead the bread vigorously and to avoid leaving any wing marks in the baked bread. However, since the kneading container 1 is rectangular, the size of the wing portion 7 is determined by the radius that extends to the side of the kneading container 1 when the wing portion rotates in a prone state, and is close to the side of the kneading container 1. The height of the wing portion 7 becomes lower as the height increases. The speed of the wing section 7 is faster near the outer periphery, and it is possible to knead strongly in this part, so the low height of the wing section 7 here is disadvantageous for kneading, so the kneading rotation speed is lowered to reduce the sound of kneading. There was a problem that it was difficult to operate the device, and this was a serious problem as a device to be operated at night.

The present invention is intended to solve the above-mentioned conventional problems, and its first object is to provide a bread making machine that can perform quiet and strong kneading and remove blade marks without using any special configuration.

The second object is to provide a bread making machine that is equipped with two wing sections and can perform quiet and strong kneading over a large area.

The third object is to provide a bread making machine that can effectively knead the outer periphery at a high speed.

Means for Solving the Problems In order to achieve the first object, the present invention includes a kneading container, a rotating shaft protruding from the inner bottom of the kneading container, and kneading blades driven by the rotating shaft, The rotary shaft has a split portion in the axial direction at its tip, and the kneading blade includes a shaft portion that can be detachably inserted into the split portion, and blades that are attached to the shaft portion and are undulating according to the rotational direction of the rotary shaft. It has a section.

In order to achieve the second objective, the kneading container is provided with a rotating shaft protruding from the inner bottom of the kneading container, and a kneading blade driven by the rotating shaft, and the kneading blade is detachably attached to the rotating shaft. It has a boss portion that can be inserted into the rotary shaft, and two wing portions that are provided on both sides of the boss portion and that rise and fall depending on the direction of rotation of the rotating shaft.

Furthermore, in order to achieve the third objective, a kneading container, a rotating shaft protruding from the inner bottom of the kneading container, and a kneading blade driven by the rotating shaft are provided, and the kneading blade is detachably attached to the rotating shaft. The rotor has a boss portion that can be inserted into the rotary shaft, a fixed wing portion that is integrated with the boss portion, and a wing portion that is located between the fixed wing portion and the boss portion and that rises and falls in accordance with the rotational direction of the rotating shaft.

Function As mentioned above, by inserting the shaft part of the kneading blade into the split part of the rotating shaft, the rotation radius of the blade part in the prone state can be increased (
The wing area can be increased in the standing state (during kneading). This allows for strong kneading even if the kneading rotation speed is lowered.

Furthermore, by providing two wing parts, the same kneading can be performed even if the rotational speed of kneading is 1/2, and quiet and strong kneading can be achieved.

Furthermore, due to the configuration of the fixed wing section and the undulating wing section, even if the rotational speed during kneading is lowered, the kneading can be strengthened at the high speed section of the kneading blades.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. 1 to 3, 10 is the main body of the automatic bread making machine, 11 is a motor, 12 is a baking chamber having a heater 13,
A kneading container 16 is detachably provided inside. A rotary shaft 14 that is rotated by transmission drive from the motor 11 projects from the inner bottom of the kneading container 16, and a kneading blade 15 is removably provided on the rotary shaft 14.

The rotating shaft 14 described above has a split part 17 in the axial direction at the center of its tip, and the kneading blade 15 has a boss part 18 and a shaft part 19 that can be detachably inserted into the split part 17. It has a wing section 20 that is attached to the shaft section 19 and that rises and falls according to the rotational direction of the rotating shaft 14.

Here, by attaching the boss portion 18 to the rotating shaft 14, kneading can be performed by inserting the shaft portion 19 of the wing portion 20 into the split portion 17 of the rotating shaft 14 and driving the motor 11. At this time, if the motor 11 rotates in the forward direction, the wing portion 20 stands up as shown by the dotted line in Figure 2 due to the resistance of the dough, and if it rotates in the reverse direction, it lies down as shown in the solid line in Figure 2. At this time, as shown in FIGS. 3a and 3b, since the wing part 20 rotates at the split part 17 (center part) of the rotating shaft 14, it becomes thicker (h + ) than the conventional structure (h + ) shown by the dotted line. h2), it is possible to knead strongly even at low speed rotation, and the noise during kneading can be reduced.In addition, since the wing section 20 is in a prone state due to reverse rotation, it is easy to take out the baked bread, and moreover, Almost no traces of the kneading blades 15 remain inside the bread.

The kneading blade 15 in FIG. 4 has a boss portion 21 that can be detachably inserted into the rotating shaft 14, two rotating shafts 22a and 22b provided on both sides of the boss portion 21, and two rotating shafts 22a and 22b. It has two wing parts 23a and 23b that are attached and undulate according to the rotational direction of the rotating shaft 14.

Then, when the motor 11 rotates forward, the two blade parts 23a, 23
b stands up (indicated by the dotted line) and performs kneading, and rotates in the opposite direction to lie down (indicated by the solid line). As a result, the rotation of the kneading blade 15 is equivalent to twice that of the kneading blade of the conventional configuration, and conversely, the rotation speed is reduced to 1.
Even if it is lowered to /2, it is possible to perform kneading equivalent to the conventional configuration, and it is possible to lower the sound during kneading. Similarly, since the bread can be placed in a prone state by reverse rotation, it is easy to take out the baked bread, and hardly any traces of the kneading blades 15 remain inside the bread.

The kneading blade 15 in FIG. 5 includes a boss portion 24 that can be detachably inserted into the rotating shaft 14, a relatively elongated upright fixed wing portion 25 provided integrally with the boss portion 24, and a boss portion of the fixed wing portion 25. 2
4, and has a wing portion 26 that rotates and freely rises and falls in accordance with the rotational direction of the rotation shaft 14.

Then, the forward rotation of the motor 11 causes the wing portion 26 to become in an upright state (indicated by a dotted line) for kneading, and the reverse rotation brings the wing portion 26 into a prone state M (indicated by a solid line). In this configuration, by configuring the outer periphery of the kneading blade 15 with an upright fixed blade part 25, the size of the blade at the part where the rotational speed is highest can be considerably increased (it is taller and stronger kneading is possible). Therefore, the rotation speed of kneading is low (it is possible to lower the sound during kneading. Also,
Since most of the wing portions 26 can be rotated to lie down, no large traces of kneading blades remain inside the baked bread, and the bread can be easily taken out.

Effects of the Invention As described above, the bread maker of the present invention is capable of kneading bread dough vigorously even at low speeds, and by lowering the rotation speed, the noise during kneading is reduced, allowing for quiet operation at night. In addition, the bread is easy to take out after baking, and the dough does not leave a thick trail inside the bread.In particular, the first invention does not require any special structure. The above-mentioned effects are obtained.The second invention performs quiet and strong kneading over a large area.The third invention effectively performs kneading at high speed on the outer periphery. be.
