Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic bread maker that is used in general households and is capable of making bread by rotary kneading flour and the like.

Conventional technology Generally, when making bread, mixer 9 fermentation machine is used.

Equipment such as rolling pins and ovens are used, but it is extremely difficult to control temperature and time, and a great deal of skill is required to make delicious freshly baked bread regardless of the time of year. To solve these problems.

An automatic bread maker has been considered that has a configuration in which kneading, fermentation, and open functions are housed in a single product as shown in FIG. 3.

In the device shown in FIG. 3, a frame 2 is provided inside a main body 1, and a motor 3 and a firing chamber 5 in which all heaters 4 are attached are fixed to the frame 2. A kneading container 7 having a kneading blade 6 is detachably attached thereto, and the rotational force of the motor 3 is applied to the kneading blade θ by a small pulley 8. Belt 9. The deceleration is transmitted by the large pulley 10 and connectors 11 and 12.

Reference numeral 13 represents an upper lid that covers the firing chamber 5, and reference numeral 14 represents a timer, temperature, and power adjustment circuit. With this configuration, when bread ingredients are put into the kneading container 7 and the timer is set, the operation starts at a predetermined time, and each process is automatically performed by the timer and temperature control, and the bread is baked at a predetermined time. It is something.

Problems to be Solved by the Invention In such a conventional configuration, the kneading blades 6 are movable from a horizontal state to a nearly vertical state, but the purpose is to improve the performance of uniformly kneading bread dough. The aim was to pursue taste. Furthermore, in order to reduce the size of the blade marks on the bread, the bread was baked by always returning the kneading blades 6 to a horizontal position before baking.

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

In this context, issues to be addressed include research into various soft processes, as well as the ease of taking out bread with a hard crust, such as fresh bread, especially the popular French bread. When taking out the bread, there are problems with the non-adhesive separation of the bread from the kneading container and the non-adhesive separation of the bread with the kneading blades 6, but the kneading container 7 is generally made of aluminum die-casting. Because it is treated with a base coating, its non-stick properties are high, and the kneading blade 6 described later
The key point is how well the bread separates.

Regarding this point, in the above-mentioned conventional example, after kneading the dough with the kneading blade 6, the kneading blade e is folded down to start baking, so that the tangled bread dough is held down between the kneading container and the kneading container under the kneading blade 6. The bread is baked with the kneading feathers θ embedded in the bottom of the bread.

In the conventional single menu of bread, the skin is relatively soft, and even if the bread is baked in such a state, when the kneading container 7 is turned upside down and pushed out to take out the bread, the kneading blades 6 touch the bottom of the bread. It was possible to remove the fabric by pulling it out.

However, in the case of French bread, etc., which has a hard skin, especially if there is a lot of dough under the blade 6, the resistance when taking out the bread increases, making it difficult to take out the bread. For this reason, there is also a method of taking out the kneading blade 6 and bread together from the kneading container 7 and then scooping out the kneading blade 6 from the bottom of the bread again, but immediately after baking, it is hot and there is a risk of burns. In this case, a separate removal jig is required, or if you inadvertently forget to remove the kneading blade 6, you may damage the knife when slicing the bread or metal chips may adhere to the inside of the bread, which is a health and safety issue. I had this problem.

The present invention solves these problems by arbitrarily selecting the pre-baking state of the kneading blades depending on the hardness and softness of the skin, thereby improving the ease of taking out the bread or the traces of the kneading blades on the bottom of the bread. The purpose of the present invention is to provide an automatic bread making machine that effectively gives priority to one of the above, enhances the product value of its usability, and is enriched with variation functions.

Means for Solving the Problems In order to achieve the above object, the present invention provides a flat blade plate of the kneading blade portion, and rotates the blade plate from a position substantially parallel to the bottom surface of the kneading container to a position substantially perpendicular to the bottom surface of the kneading container. In addition to being rotatably supported, the blade plate can be arbitrarily set in a horizontal or vertical position by a program control device before firing.

Effect According to the above structure, in the case of relatively soft bread, by raising the blade plate of the kneading blade part in a horizontal position, there will be some resistance when taking out the bread, but the range within which it can be taken out will be reduced. Inside, the feather marks on the bottom of the pan can be reduced,
On the other hand, in the case of breads with hard skins such as French bread, by setting the blades of the kneading blades vertically, the blade marks on the bottom of the bread will have a notched shape, but the amount of dough under the blades will This allows you to choose between improving the ease of taking out the bread by reducing the size of the bread. By prioritizing and selecting one of these characteristics, product functionality can be easily enhanced.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2. In the figure, 20 is the main body, 21 is the main body 2Q
A motor 22 is fixed to the chassis 21, and its rotational force is transmitted to a connector 24 located at the bottom of the firing chamber 23, and a small pulley 26. Belt 26. The signal is transmitted via the large pulley 27.

Further, a heater 28 is disposed on the inner peripheral surface of the lower part of the firing chamber 23, and a kneading container 33 is provided inside the firing chamber 23.
The kneading container 33 has a drive shaft 32 pivotally supported through a bearing 29 at the bottom, and the drive shaft 32 has a container connector 30 fixed to one side and a kneading blade part to the other. 31 is detachably attached.

When the kneading container 33 is installed in the baking chamber 23, the connector 24 and the container connector 30 of the kneading container 33 are connected to each other.
The temperature sensor 34 , which is elastically attached to the inner surface of the baking chamber 23 , comes into contact with the outer surface of the kneading container 33 .

The kneading blade portion 31 is composed of a blade bearing portion 35 that fits into the drive shaft 32 and a flat blade plate 36, which are connected by a blade pin 37, and the blade plate 36 is connected to the blade pin 37. It is possible to rotate the kneading container 33 from a position approximately parallel to the bottom surface of the kneading container 33 to a position approximately perpendicular to the bottom surface of the kneading container 33 as shown by the arrow. The vertical position indicated by the two-dot chain line is regulated by the blade plate 360 surface being in contact with the side surface of the blade bearing portion 36 .

Further, above the baking chamber 23, a lid 4o to which a yeast container 39 with an on-off valve 38 attached to its bottom is fixed is attached so that it can be opened and closed from the front via a rear hinge shaft. 41 receives information from the temperature sensor 34, etc.;
This is a program control device that controls the output of the motor 22 and heater 28 according to a set menu.

In the above configuration, the operation of this embodiment will be explained next. First, the kneading container 33 is set in the baking chamber 23. In this case, the kneading container 33 has the kneading blade part 31 attached to the inner bottom and contains bread ingredients other than yeast such as flour and water. When the setting of the kneading container 33 is completed, the lid 4o is closed and a predetermined amount of yeast is put into the yeast container 39. In this state, input the bread menu and bread rising time from the switch panel (not shown) and start. When the predetermined time has elapsed, the motor 22
starts to rotate, the small pulley 26 rotates, and the belt 26
Drive is transmitted to the dog pulley 27 and the connector 24 via the kneading container 33 to rotate the kneading blade portion 31 in the kneading container 33.

This crosstalk is repeated in a detailed manner, with forward and reverse rotations at different times.

After a predetermined time period for this kneading has elapsed, the on-off valve 38 of the yeast container 39 is opened and yeast is introduced into the kneading container 33. After this yeast is kneaded with other bread ingredients for a predetermined time, the temperature of the kneading container 33 is adjusted by the heater 28 while inputting the temperature information from the temperature sensor 34 based on the process control of the program controller 41. - Each step of next fermentation, degassing, shaping fermentation, and baking is performed automatically according to the bread menu, and the bread is baked at the set time.

Here, when the kneading blade section 31 is rotated in the normal direction, the blade plate 36 rotates and kneads the bread dough in a state almost perpendicular to the bottom surface of the kneading container 33, and when the kneading blade part 31 is reversed, the blade plate 36 falls down. The bread dough is rotated in a substantially horizontal state with the bottom surface of the kneading container 33, and in this case, the bread dough is rotated in the vertical direction and kneaded.

In the present invention, the motor 22 is further driven before baking, and the kneading blade part 31 is finally rotated several times in the normal direction so that the blade plate 36 is approximately perpendicular to the bottom surface of the kneading container 33. Or, on the other hand, turn the blade plate 36 over the kneading container 3.
It is programmed to select whether to position the bread in a position substantially parallel to the bottom of the bread pan 3 and then proceed to baking, depending on the bread menu.

This means that, for example, when making bread with relatively soft dough as in the past, or bread with a light soft touch after baking, the kneading blade part 31 is inverted and the blade plate 3 is
6 and baking in a position almost parallel to the bottom of the kneading container 33, the recess of the blade marks on the bottom of the bread after baking will be relatively shallow.In this case, even if the bread is sliced, the bottom of the bread will not be has only a slight dent, and also has a slight dent (
Even when taking out the dough, even if there is a large amount of dough under the kneading blade part 31 or the bread skin is torn, it can be easily taken out.

On the contrary, the skin is baked hard, as is typical of French bread.
- In the case of a dotouch bread menu, kneading blade part 31
If the blade plate 36 is rotated in the normal direction and baked with the blade plate 36 in a state almost perpendicular to the bottom surface of the kneading container 33, the amount of dough under the kneading blade part 31 will be significantly reduced, and the resistance when taking out the bread will be reduced. On the other hand, when the kneading container 33 is turned upside down and extruded, the weight of the bread is concentrated on the lower surface of the plate 3e, and the dough is cut into pieces due to the knife effect, making it easier to take out the dough. According to
This solves the problem of not being able to take out the bread when the wing plate 36 falls down. However, regarding the feather marks on the bottom of the bread, although the concave portion in appearance becomes smaller, the notch remains.

As a consideration in the present invention, it is desirable to have a low shape for the blade plate 36 that reduces the amount of cut described above, but the results of this experiment show that if it is made into a plate shape and a tangling part is formed in the center,
The effectiveness of L-shaped blades, which allow the height of the blades in the radial direction to be set low, has been confirmed, and is helpful in taking the above measures.

In addition, in this example, the kneading blade part 3 is
1 is rotated, and finally the blade plate 36 is placed in a position approximately parallel to the bottom surface of the kneading container 33, or in a position approximately perpendicular to the bottom surface of the kneading container 33, but is not limited to this. It may also be implemented by

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention,
The blade plate of the kneading blade part that fits into the drive shaft at the bottom of the kneading container is shaped like a flat plate, and the blade plate is rotatably supported from a position substantially parallel to the bottom surface of the kneading container to a position substantially perpendicular to the bottom surface of the kneading container. By using a program control device, the blade plate can be set to any horizontal or vertical position before baking, so it can be used for bread menus with a comparatively high quality, as well as bread menus with hard crusts such as French bread. Depending on the case, you can prioritize either the ease of taking out the bread or the feather marks on the bottom.
This makes it possible to increase the product value of the product in terms of its ease of use, and to enrich and expand the bread menu. Furthermore, with this configuration of the present invention, there is no need to employ a plurality of kneading blade parts, and there is no need to separately provide a kneading blade removal jig, etc.
It is possible to provide an automatic manufacturing machine that is inexpensive and easy to use.
