Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an automatic bread maker that can easily make bread at home.

``Conventional technology'' Conventional automatic bread making machines require that all ingredients such as flour, yeast (hereinafter referred to as yeast), sugar, and water be placed in the baking pot in advance, or that ingredients other than water be placed in the baking pot. Bread dough was made by kneading the ingredients using rotating blades placed inside the oven while water from a water tank was dripped into the oven. Therefore, for example, when trying to make so-called pre-baked bread by setting a timer so that the bread is baked after a predetermined time, it is necessary to be careful about the order in which the ingredients are added and how they are handled. In other words, if water and yeast came into contact with each other after the ingredients were set, the yeast would ferment before the ingredients were kneaded, and it would sometimes be impossible to make high-quality bread. Therefore, for example, you can first put water in a baking pot, then add flour on top of it, and then put yeast on top of the flour, or you can put yeast in the center of the bottom of the baking pot and cover it. It was necessary to prevent immediate contact between the water and the yeast by adding flour to the container and dripping water onto the flour.

On the other hand, there have traditionally been various ways to make bread by hand. For example, some of the ingredients for making bread, such as flour, are kneaded with water.
Bread dough is then made by adding the remaining ingredients such as yeast and kneading. Further, for example, when making bread with curry flavor or matcha flavor, some of the ingredients are kneaded first as described above, and then curry powder and matcha are added and kneaded. but,
Conventional bread making machines have been unable to automatically feed such ingredients into the baking oven after a predetermined period of time, which poses a problem when making reservations for bread making.

``Means for Solving the Problems'' In this invention, a flour storage container is provided at the top of the baking pot, a shutter is provided at the bottom of the flour storage container that is operated at a predetermined time, and when the shutter is opened, the flour storage container is Allow the stored materials to be put into the baking pot. In other words, if you store yeast, etc. in the flour storage container, you can prevent it from coming into contact with water until the shutter is opened.In addition, you can also store yeast, etc. in the flour storage container, and prevent it from coming into contact with water until the shutter is opened. After a predetermined period of time, the food can be automatically placed in the roasting pot.

``Embodiments of the Invention'' FIG. 1 shows the entire automatic bread making machine. 11 in the diagram

In this example, an ice container 18 is provided around the outer periphery of the water tank 15 so that the water stored in the water tank 15 can be cooled in advance, and ice 19 can be stored in the ice container 18. A heat insulating material 21 is placed over the outer periphery of the ice container 18 to provide insulation between the outside air and the ice container 18. In addition, the powder storage container 14, water tank 15, and ice container 18 are all covered with a lid 22 made of a heat insulating material, and the containers 14, 15, and 18 covered with the heat insulating material 21 are removed from the casing 11 as one body. The structure is such that it is possible to

The means for transferring the material 13 from the powder storage container 14 to the baking oven 16 at a predetermined time can be constructed as shown in FIG. 2, for example. In other words, in the example shown in FIG. 2, the shutter 23 is provided on the bottom of the powder storage container 14,
A case is shown in which the material 13 is dropped into the baking oven 16 by automatically opening the shutter 23 at a predetermined time.

As a drive mechanism for the shutter 23, for example, a third
As shown in the figure, the shutter 23 is rotatably supported on a shaft 26, and the shutter 23 is supported by a spring 27.

A rotating pawl 29 is provided in response to the rotational biasing force of the spring 27, and the rotating pawl 29 is engaged with a lever 31 protruding from the shaft 26, and this engagement maintains the shutter 23 in the closed state. An electromagnetic plunger 32 is connected to the rotating claw 29,
A structure is shown in which the electromagnetic plunger 32 is operated at a predetermined time to disengage the rotating pawl 29 and the lever 31, thereby operating the shutter 23 into the open state by the biasing force of the spring 27.

Also shown is a structure in which a pot 24 is provided on the bottom of the water tank 15, and water in the water tank 15 is poured into the baking pot 16 through a pipe 25 by automatically opening the pot 24 at a predetermined time.

For example, as shown in FIG.
4 are connected, and a spring 34 applies a biasing force to the operating lever 33 in the direction of opening the lock 24. A rotating lever 35 is provided with respect to the operating lever 33, and the rotating lever 35 is engaged with the operating lever 33.

An electromagnetic plunger 36 is connected to the rotating lever 35, and by operating the electromagnetic plunger 36 at a predetermined time, the rotating lever 35 and the operating lever 33 are disengaged, and the operating lever 33 is rotated by the biasing force of the spring 34. move it,
It is possible to have a structure in which the lock 24 is operated to an open state.

For example, as shown in FIGS. 1 and 2, the baking oven 16 is equipped with a kneader 37 on the bottom, and the kneader 37 kneads the material 13 and water dropped from the storage container 14 and the water tank 15 to make bread dough. It has the ability to create. The kneader 37 can be constructed, for example, by a rotating blade 37a provided on the bottom surface of the roasting pot 16 and a fixed rod 37b projecting from the top of the rotating blade 37a. By providing the fixed rod 37b above the rotating blade 37a, the rotating blade 37a
The material 13 can be effectively kneaded by the cooperation of the fixed rod 37b and the rotational speed of the rotary blade 37a can be set to be low. By being able to set the rotational speed of the rotary blades 37a to be slow, there is an advantage that noise can be reduced during kneading. A heat-sensitive element is housed in the axis of the fixed rod 37b, and the temperature of the bread dough is measured by this heat-sensitive element. Reference numeral 38 indicates a motor that drives the kneader 37, and shows a structure in which rotational force is transmitted to the kneader 37 by a belt transmission mechanism 39.

A controller 41 is provided inside the case 11. When the finish time is set in this controller 41,
In order to be in time for this finishing time, the starting time for kneading the ingredients is determined by backward calculation, and the rotary blade 37a is activated, and the ingredients 13 put in the baking pot 16 and water are kneaded to form bread dough. As mentioned above, among the ingredients 13, for example, flour, sugar, etc. are added to the baking pot 1 in advance.
6, and when yeast, curry powder, matcha, etc. are stored in the powder storage container 14, water is supplied to the flour, sugar, etc. in the baking pot 16 to start kneading, and then kneading is carried out in the specified manner. If the shutter 23 is set to open at the specified time, yeast, curry powder, matcha, etc. can be added after kneading a portion of the ingredients 13 as in the case of conventional handmade dough. When the temperature of the dough rises to about 27°C to 29°C is detected by the heat-sensitive element attached to the fixed rod 37b, the operation of the kneader 37 is stopped, and the heater 17 is energized after primary fermentation, degassing, and secondary fermentation. do. The controller 41 sequentially controls this series of operations.

The top of the baking pot 16 is covered with a lid 42.
The structure is such that the baked bread can be taken out from the baking oven 16 by removing it. Lid 4
2 has a hole 43 in the center thereof, and the material 13 and water are dropped into the baking pot 16 through this hole 43.

Since the hole 43 is for dropping the material 13, its opening area is relatively large. For this reason, when baking bread, if the hole 43 is open, water will evaporate from the baking pot 16.
Therefore, in this embodiment, a means for closing the hole 43 is provided at least before starting the bread baking process.

44 indicates a shutter that closes the hole 43. This shutter 44 is rotatably attached to the lid 42 and is automatically operated by a mechanism as shown in FIGS. 5 to 7, for example, to close the hole 43. In other words, in this example, the rotating blade 37a that constitutes the kneader 37
When the rotating blade 37a starts rotating, the lever 45
The lever 45 is rotated by the biasing force of the spring 46, and this rotation disengages the lever 45 from the shutter 44. The shutter 44 is then rotated by its own weight to close the hole 43. Indicates the case configured.

In other words, the lever 45 is supported by a shaft 47 so as to be rotatable in a direction perpendicular to the plane of the paper in FIG.
When the shutter 44 is in the open state, the relationship between the lever 45 and the spring 46 is as shown by the solid line in FIG. Therefore, the lever 45 is rotated clockwise around the shaft 47 by the biasing force of the spring 46, and engages with a protrusion 48 formed on the shutter 44 to hold the shutter 44 in an open state. . A protrusion 49 is formed on the projecting piece 48, and the free end of the lever 45 engages with this protrusion 49 to lock the biasing force of the spring 46 and maintain the rotational position of the lever 45 at the solid line position shown in FIG. It has a structure.

When the shutter 44 is in the open state, the lever 45
When the rotating blade 37a starts rotating, the rotating blade 37a engages with the tip of the lever 45, and the arrow 51 shown in FIG.
is subjected to a biasing force in the direction of . When the tip of the lever 45 is moved in the direction of the arrow 51, the spring 46 passes through the position of the shaft 47 and the direction of the rotational biasing force applied to the lever 45 is reversed. By reversing the direction of the rotational biasing force, the lever 45 rapidly rotates counterclockwise under the biasing force of the spring 46 to reach the position shown by the chain line in FIG. When the lever 45 reaches the position indicated by the chain line in FIG. 7, the projection 48 disengages from the lever 45 and rotates under its own weight, closing the hole 43 as shown in FIG. 6.

FIGS. 8, 9, and 10 to 12 show other embodiments of the drive mechanism for the shutter 44 that closes the opening of the baking oven 16. In these embodiments, a structure is shown in which the hole 43 is closed inside the baking pot 16.

In the example shown in FIGS. 8 and 9, the rotary lever 45
A structure is shown in which a protrusion 52 is provided at and the shutter 44 is pushed up by the protrusion 52. In other words, the shutter 44 is rotatably supported on the back side of the lid 42 and hangs down inside the roasting pot 16 through the hole 44.
is maintained open. Lever 45 is shutter 4
4, it is in the position shown by the chain line in FIG.

When the kneader 37 is activated and the rotary blade 37a starts rotating, a force is applied to the lever 45 in the direction of the arrow 51 shown in FIG.
7 in a counterclockwise direction, and at this time, the protrusion 52 pushes up the shutter 44 and closes the hole 43.

The embodiment shown in FIGS. 10 to 12 shows a case in which the shutter 44 is rotated in a direction parallel to the surface of the hole 43 to close the hole 43. That is, a support piece 44a is formed protruding from the shutter 44, and the tip of the support piece 44a is rotatably supported by a shaft 53 on the back side of the lid 42, thereby supporting the shutter 44 so as to be rotatable in the horizontal direction. The free end of the lever 45 is engaged with one side of the support piece 44a, and by applying a force in the direction of the arrow 51 shown in FIG. 12 to the tip of the lever 45 from the rotary blade 47a, the lever 45 The first to cancel axis 47
2 is rotated counterclockwise from the state shown in FIG. 2, and the shutter 44 is rotated in the direction of the arrow 54 to close the hole 43.

As for the drive mechanism of the shutter 44, as another structure, the shutter 44 is attached so as to be slidable along the plate surface of the lid 42, and the lever 45 is connected to the rotating blade 37a.
It is also possible to adopt a structure in which the shutter 44 is moved by the biasing force of a spring to close the hole 43 when the shutter 44 is moved by the spring.

In this example, water from the water tank 15 is supplied to the baking pot 16, but since the flour storage container 14 is provided above the baking pot 16, if yeast is placed in this powder storage container 14, for example, Even if water is placed in the baking pot 16 in advance as in a conventional bread maker, the water and yeast will not come into contact until the shutter 23 is opened at a predetermined time.

"Effects of the Invention" In this invention, the powder storage container 14 is provided at the top of the baking pot 16, and the shutter 23, which is operated at a predetermined time, is provided at the bottom of the flour storage container 14. Since the material stored in the container 14 is placed into the baking pot 16, the material stored in the powder storage container 14 is automatically placed into the baking pot 16 a predetermined time after the material is set. It becomes possible to do so. Therefore, by storing yeast, etc. in the flour storage container 14, contact between the yeast and water can be prevented until the shutter 23 is opened, and the yeast will not ferment before the materials are kneaded. I can make bread. In addition, when the flour storage container 14 cannot store all the ingredients for making bread, or intentionally, flour, sugar, water, etc. It is also possible to store it. Therefore, if the flour, sugar, water, etc. stored in the baking pot 16 are kneaded first, and then the shutter 23 is opened,
Since the yeast, curry powder, matcha, etc. stored in the flour storage container 14 can be automatically added later, it is possible to make high-quality bread using a method similar to the handmade method described in the section of ``Prior Art''. Moreover, it is also possible to automatically make bread with curry flavor or matcha flavor. Furthermore, if the capacity of the powder storage container 14 and the material input port provided at the bottom of the container 14 are made slightly larger as in the example shown in the drawings, it is possible to store not only powdered materials in the powder storage container 14, but also materials that can be used, for example. It becomes possible for the person to add raisins and the like as appropriate, and it also becomes possible to automatically make grape bread and the like.

In addition, when the ice container 18 is provided as shown in the embodiment, even in summer, the material in the powder storage container 14 can be
It is possible to cool the dough to about 15°C, and the time required for the temperature of the dough to rise to about 27°C to 29°C during the kneading process can be extended to about 15 to 16 minutes, making it possible to produce high-quality bread dough. Obtainable.
