Abstract

PURPOSE:To strongly knead a batch of dough in a short time period by a method wherein a kneading blade is supported free to turn around an axis from the bottom of a kneading bowl up to an upper position, and the upper edge of the blade tilts forward against the rotating direction of a kneading assembly when the blade is at a raised position. CONSTITUTION:A kneading blade assembly 18 consists of a bladed bearing part 16 that is mounted on a driving shaft 12 and a blade 17 that is connected to the bearing part 16 by a pin 18. The blade 17 is rotatable around the pin 18 from a horizontal position to a raised position. When the kneading blade assembly 14 is rotated in normal direction, the blade 14 rises up to a position where the upper edge 17a of the blade 17 tilts forward against the normal rotating direction to knead the dough. At this time, as the upper edge 17a of the blade 17 tilts forward against the rotating direction, the dough is kneaded while it is pushed down toward the bottom of a bowl 10, so that the rotation of the blade 17 is transmitted to the dough without a loss, and the dough is strongly kneaded in a short time period. When the kneading assembly 14 is reversed, the blade 17 falls down and rotates while the blade remains at a position almost parallel to the bottom of the bowl, so that the dough is kneaded while it is turned up and down.

The bread is baked at a predetermined time by automatically performing each step using a timer and temperature control.

Problems to be Solved by the Invention In the above conventional configuration, the kneading blades 36 are rotatable from a horizontal state to an upward position.
When the bread dough is stood up, its tip 36a is retracted with respect to the direction of rotation, so the bread dough is kneaded in such a manner as to be pushed upward.

However, in recent years, consumer needs have diversified, and it has been desired to expand the bread menu and expand the functionality of the same menu, from hard bread to soft bread.

In this context, the challenge was to research various soft processes and to knead dough strongly in a short period of time for soft bread with one skin. Regarding this kneading performance, the larger the area of the linear blade 36, the better it is.
Since the kneading blade 36 has a rotatable structure, it is necessary to make the size such that when the kneading blade 36 becomes parallel to the bottom surface of the kneading container 37, its tip 36 & does not touch the side surface of the kneading container 37. Since the area of the blades 36 cannot be increased unnecessarily, the kneading performance had to be improved by other methods.

The present invention is intended to solve these problems, and aims to provide an automatic bread making machine that can knead bread dough strongly in a short period of time and is fully equipped with functions for a variety of breads from hard bread to soft bread. .

Means for Solving the Problems In order to eliminate the above object, the present invention has a blade plate rotatably supported from a position substantially parallel to the bottom of the kneading container to an upper position, and when the blade plate is raised, the blade plate is rotated. The upper part is tilted forward with respect to the rotating direction of the kneading blade part.

Function According to the above structure, when the blade plate is raised, the upper part of the blade plate is tilted forward with respect to the rotating direction of the kneading blade part, so that the dough is kneaded while being pressed against the inner bottom of the kneading container, and does not escape upward. As a result, the rotation of the two bladed plates is transmitted to the bread dough without waste, and it is possible to knead the dough strongly in a short time, so it can be used for kneading when making soft bread with one skin.

EXAMPLE Hereinafter, an example of the present invention will be described based on the attached page. 1 and 2, a chassis 2 is provided inside the main body 1, and a motor 3 is fixed to the chassis 2, and its rotational force is transmitted to a connector 6 located at the bottom of the firing chamber 4. Small pulley-6, belt 7, large pulley-8
transmitted via.

Further, a heater 9 is arranged on the inner peripheral surface of the lower part of the firing chamber 4, and a kneading container 10 is detachably installed inside the firing chamber 4, and a bearing 1 is mounted on the bottom of the kneading container 10.
1 to support a drive shaft 12, and this drive shaft 12
A container connector 13 is fixed to one end, and a kneading blade part 14 is detachably attached to the other end. When the kneading container 1° is installed in the baking chamber 4, the connector 6 and the container connector 13 of the kneading container 10 are connected, and the temperature at which the kneading container 1° is elastically attached to the inner surface of the baking chamber 4 The sensor 16 is in contact with the outer surface of the kneading container 10.

The kneading blade part 14 is composed of a blade bearing part 16 that fits on the drive shaft 12, and a blade plate 17, which are connected by a blade pin 18, and the blade plate 17 is connected to a blade pin 18.
It can be rotated about the axis from a position approximately parallel to the bottom surface to an upward position.

The upper position is regulated by the surface of the blade plate 170 coming into contact with the side surface of the blade bearing part 16, so that the upper part 1T& of the blade plate 1T stops at a position tilted forward with respect to the rotational direction of the kneading blade part 14. There is.

Further, above the baking chamber 4, a lid body 21, which fixes a yeast container 2o with an on-off valve 19 attached to its bottom surface, is attached so as to be openable and closable from the front via a rear hinge shaft. 22 receives information from the temperature sensor 16, etc., and controls the motor 3 and heater 9 according to the set menu.
This is a program control device that controls the output of the

Next, the operation of the configuration of the above embodiment will be explained.

First, the kneading container 10 is set in the baking chamber 4. In this case, the kneading container 1o has a kneading blade part 14 attached to the inner bottom and contains bread ingredients such as flour and water other than yeast. and.

When this setting of the kneading container 1o is completed, the lid 21 is closed and a predetermined amount of yeast is put into the yeast container 20. In this state, enter the bread menu and bread rising time on the switch panel (not shown) and start. When a predetermined time has elapsed, the motor 3 starts to rotate, the small pulley 6 rotates, and the drive is transmitted to the large pulley 8 and the connector 6 via the belt 7 to rotate the kneading blade part 14 in the kneading container 10. let And this kneading goes in the right direction.

The reversal is repeated in detail at different times. Here, when the kneading blade part 14 is rotated in the normal direction, the upper part 17& of the blade plate 17 rises to a position tilted forward with respect to the normal rotation direction of the kneading blade part 14.

Knead the bread dough. At this time, since the upper part 17a of the blade plate 17 is tilted forward with respect to the rotation direction, the dough is kneaded while being pressed against the inner bottom of the kneading container 10, and cannot escape upward, so that the blade plate 170 rotates. It is transferred to the bread dough without any waste and can be kneaded strongly in a short time. Furthermore, if the wire blade part 14 is reversed, the single blade plate 17 will fall down and rotate in a state almost horizontal to the bottom of the kneading container 10.In this case, the dough will rotate in the vertical direction and the kneading will be interrupted. It is done.

When a predetermined time period for this kneading has elapsed, the on-off valve 19 of the yeast container 20 is opened and yeast is introduced into the kneading container 10. This yeast is then kneaded with other bread ingredients for a predetermined period of time.

At this time, as described above, when the kneading blade part 14 rotates normally, one piece of dough is pressed against the inner bottom of the kneading container 10 and is kneaded strongly.

After that, the temperature of the kneading container 10 is adjusted by the heater 9 while inputting the temperature information from the temperature sensor 16 based on the process control of the program control device 22, and - the next fermentation.
The degassing, shaping fermentation, and baking processes are automatically performed according to the bread menu.

The bread will be baked at the set time.
