JP 2000-116526 A Japanese Patent No. 3191645

  In the past, when making bread, it was necessary to start by obtaining flour obtained by milling grains such as wheat and rice, and mixing flour mixed with various auxiliary ingredients. Even with grain at hand (typically rice), it was difficult to make bread directly from it.

  The present invention has been made in view of the above points, and provides an automatic bread maker equipped with a convenient mechanism for manufacturing bread directly from cereal grains, and aims to make bread manufacturing more familiar. And

  In order to achieve the above object, the present invention provides an automatic bread maker that receives a bread container containing a bread-making raw material in a baking chamber in a main body and performs the kneading process, fermentation process, and baking process of the bread-making raw material. A blade kneading and pulverizing blade is mounted on a blade rotation shaft provided at the bottom of the bread container, and the kneading and pulverizing blade performs kneading when the blade rotation shaft rotates in the forward direction. It is characterized by crushing when rotating in the opposite direction.

  According to this structure, the bread-making raw material can be manufactured in the bread container by putting the grain into the bread container and pulverizing it with the kneading and pulverizing blade. Thereafter, the bread-making raw material is kneaded with a blade for both kneading and pulverization, and the fermentation and baking steps can be further advanced. Grain grains crushed in a bread container can be baked into bread in the bread container as they are, so that the grains remain in other containers, unlike crushed grains in other containers and then transferred to the bread container. There is no loss associated with the transfer, that is, not entering the bread container. Also, from the crushing of grain to the baking of bread, the kneading and crushing blade can be kept in the bread container, and the crushing and kneading can be switched simply by reversing the rotation direction of the blade rotation shaft. Because it can, it is easy to operate.

  Further, the present invention is the automatic bread maker configured as described above, wherein the kneading and pulverizing blade includes a movable blade that can be tilted and formed with a pulverizing edge on one edge, and the movable blade includes the blade rotation shaft. When the blade rotates in the forward direction, it takes a standing posture, and when the blade rotation shaft rotates in the reverse direction, it takes a horizontal posture.

  According to this configuration, the kneading / pulverizing blade can be formed into a shape suitable for kneading at the time of kneading and a shape suitable for pulverization at the time of pulverization, with a simple configuration in which the movable blade is erected or leveled.

  Further, the present invention provides an automatic bread maker having the above-described configuration, wherein an inclined portion is formed on the edge opposite to the crushing edge of the movable blade, with one surface being a downward slope and the other surface being an upward slope. When the blade rotation shaft rotates in the forward direction, the inclined portion converts the pressure received from the bread-making material in the bread container into the standing moment of the movable blade, and the blade rotation shaft rotates in the reverse direction. In some cases, the pressure received from the bread-making material in the bread container is converted into a horizontal maintenance moment of the movable blade.

  According to this configuration, since the shape of the kneading / pulverizing blade is automatically changed according to the rotation direction of the blade rotation shaft, it is not necessary to change the shape of the kneading / pulverizing blade.

  In the automatic bread maker having the above-described configuration, the kneading and pulverizing blade includes a fixed blade having a pulverization edge formed on one edge, and the fixed blade has an edge opposite to the pulverization edge. And a kneading pressing surface, and an inclined surface is formed between the crushing edge and the upper end of the kneading pressing surface.

  According to this configuration, the kneading and pulverizing blade has no moving parts, so that it is easy to design and manufacture and is robust. The kneading and pulverizing blade can be easily cleaned.

  According to the present invention, bread can be baked using hand-held grains, and there is no need to purchase grain flour. In the case of rice, bread can be baked with rice of the desired degree of milling, from brown rice to white rice. And since it can consistently perform in the bread container in a baking chamber from the grinding | pulverization of a grain grain to baking of a bread | pan, there is little danger that a foreign material will mix in bread dough. Furthermore, unlike the case where the grain is crushed in another container and then transferred to the bread container, there is no loss associated with the transfer in which the pulverized grain remains attached to the other container. Also, from the crushing of grain to the baking of bread, the kneading and crushing blade can be kept in the bread container, and the crushing and kneading can be switched simply by reversing the rotation direction of the blade rotation shaft. Because it can, it is easy to handle.

  Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the left side of the figure is the front (front) side of the automatic bread maker 1, and the right side of the figure is the back (rear) side of the automatic bread maker 1. Further, it is assumed that the left hand side of the observer facing the automatic bread machine 1 from the front is the left side of the automatic bread machine 1, and the right hand side is the right side of the automatic bread machine 1.

  The automatic bread maker 1 has a box-shaped main body 10 constituted by an outer shell made of synthetic resin. A handle 11 for transportation is attached to the upper part of the main body 10. An operation unit 20 is provided on the front surface of the main body 10. As shown in FIG. 3, the operation unit 20 has operation keys such as a bread type selection key (flour bread, rice flour bread, bread with ingredients), cooking content selection key, timer key, start key, cancel key, and the like. A group of 21 and a display unit 22 for displaying set cooking contents, timer reservation time, and the like are provided. The display unit 22 is configured by a liquid crystal display panel.

  The upper surface of the main body behind the operation unit 20 is covered with a lid 30 made of synthetic resin. The lid 30 is attached to an edge on the back side of the main body 10 with a hinge shaft (not shown), and rotates in a vertical plane with the hinge shaft as a fulcrum.

  A firing chamber 40 is provided inside the main body 10. The baking chamber 40 is made of sheet metal and has an open top surface, from which a bread container 50 is placed. The baking chamber 40 includes a peripheral side wall 40a and a bottom wall 40b having a rectangular horizontal section.

  A base 12 made of sheet metal is installed inside the main body 10. On the base 12, a bread container support 13 made of an aluminum alloy die-cast product is fixed at a location corresponding to the center of the firing chamber 40. The inside of the bread container support part 13 is exposed inside the baking chamber 40.

  A driving shaft 14 is vertically supported at the center of the bread container support 13. A pulley 15 is fixed to the lower end of the driving shaft 14.

  The pulley 15 is rotated by a motor 60 supported by the base 12. The motor 60 is a saddle shaft, and the output shaft 61 protrudes from the lower surface. A pulley 62 connected to the pulley 15 by a belt 63 is fixed to the output shaft 61.

  The bread container support unit 13 supports the bread container 50 by receiving a cylindrical pedestal 51 fixed to the bottom surface of the bread container 50. The pedestal 51 is also an aluminum alloy die cast product.

  The bread container 50 is made of sheet metal and has a bucket-like shape, and a handle (not shown) for handbags is attached to the lip. The horizontal cross section of the bread container 50 is a rectangle with rounded four corners, and ridge-like protrusions 50a extending in the vertical direction are formed on the inner surfaces of two opposite sides of the four sides.

  A blade rotation shaft 52 (see FIG. 2) is vertically supported at the center of the bottom of the bread container 50 after taking measures against sealing. A rotational force is transmitted to the blade rotating shaft 52 from the driving shaft 14 through the coupling 53. Of the two members constituting the coupling 53, one member is fixed to the lower end of the blade rotation shaft 52 and the other member is fixed to the upper end of the driving shaft 14. The entire coupling 53 is enclosed by the base 51 and the bread container support 13.

  Protrusions (not shown) are formed on the inner peripheral surface of the bread container support 13 and the outer peripheral surface of the base 51, respectively. These protrusions constitute a well-known bayonet connection. That is, when the bread container 50 is attached to the bread container support part 13, the bread container 50 is lowered so that the protrusions of the base 51 do not interfere with the protrusions of the bread container support part 13, and the base 51 fits into the bread container support part 13. Thereafter, when the bread container 50 is twisted horizontally, the protrusion of the pedestal 51 is engaged with the lower surface of the protrusion of the bread container support portion 13 so that the bread container 50 cannot be pulled upward. By this operation, coupling of the coupling 53 is achieved at the same time. The twisting direction at the time of attaching the bread container 50 is made to coincide with the rotation direction at the time of kneading and pulverizing blades described later so that the bread container 50 does not come off by kneading.

  A heating device 41 disposed inside the baking chamber 40 surrounds the bread container 50 and heats the bread-making material. The heating device 41 is constituted by a sheathed heater.

  A blade 70A for kneading and pulverization is attached to the upper end of the blade rotating shaft 52. The kneading and pulverizing blade 70A includes a hub 71 that is non-rotatably fitted to the blade rotating shaft 52, a fixed blade 72 that protrudes in a horizontal direction from one side surface of the hub 71, and a horizontal direction from the other side surface of the hub 71. The movable blade 73 protrudes. In the fixed blade 72 and the movable blade 73, a crushing edge 74 is formed on the edge on the side that becomes the front edge when the blade rotation shaft 52 rotates counterclockwise as viewed from above.

  The movable blade 73 is rotatably attached to the hub 71 by a support shaft 75, and can be changed in posture between a horizontal posture shown in FIGS. 1 to 3 and a standing posture shown in FIGS. In the movable blade 73, an inclined portion 76 is formed on the opposite edge to the crushing edge 74, with one surface being a downward slope and the other surface being an upward slope. When the blade rotation shaft 52 rotates in the clockwise direction when viewed from above (this rotational direction is referred to as “positive direction” in the present specification), the inclined portion 76 moves the pressure received from the bread-making material in the bread container 50. As a result, the movable blade 73 that has been in the horizontal posture stands upright. When the blade rotation shaft 52 rotates counterclockwise when viewed from above (this rotational direction is referred to as “reverse direction” in this specification), the inclined portion 76 receives the pressure received from the bread-making material in the bread container 50. The movable blade 73 is switched to a horizontal maintenance moment, and as a result, the movable blade 73 maintains a horizontal posture.

  A groove (not shown) is formed in the lower surface of the hub 71 so as to cross the diametrical direction. A pin (not shown) penetrating the blade rotation shaft 52 horizontally receives the hub 71 and engages with the groove, so that the hub 71 is non-rotatably coupled to the blade rotation shaft 52. Since the kneading and pulverizing blade 70A can be easily pulled out from the blade rotating shaft 52, it is possible to easily perform washing after the bread making operation and replacement when the cutting edge 74 becomes dull.

  Operation control of the automatic bread maker 1 is performed by the control device 80 shown in FIG. The control device 80 is configured by a circuit board disposed at an appropriate location in the main body 10 (preferably a location that is not easily affected by the heat of the baking chamber 40). In addition to the operation unit 20 and the heating device 41, the motor driver 81 of the motor 60 is provided. And a temperature sensor 83 is connected. The temperature sensor 83 is disposed in the baking chamber 40 and detects the temperature of the baking chamber 40. 84 is a commercial power source for supplying power to each component.

  Then, the process of manufacturing bread from cereal grains using the automatic bread maker 1 will be described with reference to FIGS. 8 to 16. Among them, the first embodiment bread manufacturing process is shown in FIGS. 8 to 13.

  FIG. 8 is an overall flowchart of the first aspect bread manufacturing process. In FIG. 8, the process proceeds in the order of impregnation process before grinding # 10, grinding process # 20, kneading process # 30, fermentation process # 40, and firing process # 50. Then, the content of each process is demonstrated.

  In the pre-grinding impregnation step # 10 shown in FIG. 9, first, in step # 11, the user weighs the grain and puts a predetermined amount into the bread container 50. Rice grains are most easily available as grains, but other grains such as wheat, barley, straw, buckwheat, buckwheat, corn and the like can also be used.

  In step # 12, the user weighs the liquid and puts a predetermined amount into the bread container 50. A common liquid is water, but it may be a liquid having a taste component such as broth or fruit juice. Alcohol may be contained. Note that the order of step # 11 and step # 12 may be switched.

  The operation of putting the grain and liquid into the bread container 50 may be performed by removing the bread container 50 from the baking chamber 40 or may be performed while the bread container 50 is placed in the baking chamber 40.

  When the grain and liquid are put in the bread container 50 in the baking chamber 40, or when the bread container 50 containing the grain and liquid is attached to the bread container support part 13, the lid 30 is closed. Here, the user presses a predetermined operation key in the operation unit 20 to start the liquid impregnation time count. Step # 13 starts from this point.

  In Step # 13, the mixture of the grain and the liquid is allowed to stand in the bread container 50, and the grain is impregnated with the liquid. In general, since the impregnation is promoted as the liquid temperature increases, the heating means 41 may be energized to increase the temperature of the baking chamber 40.

  In step # 14, the control device 80 checks how much time has elapsed since the start of the resting of the grain and liquid. When the predetermined time has elapsed, the pre-grinding impregnation step # 10 ends. This is notified to the user by display on the operation unit 20 or by voice.

  Subsequent to the impregnation step # 10 before pulverization, the pulverization step # 20 shown in FIG. 10 is performed. Step # 21 is started when the user inputs grinding operation data (type and amount of grain, type of bread to be baked, etc.) through the operation unit 20 and presses the start key.

  In step # 21, the control device 80 drives the motor 60 to rotate the blade rotation shaft 52 in the reverse direction. Then, the kneading / pulverizing blade 70A starts rotating in the mixture of the grain and liquid. The kneading and pulverizing blade 70 </ b> A pulverizes the grain with the pulverizing edge 74 of the fixed blade 72 and the movable blade 73. The movable blade 73 maintains a horizontal posture at this time. The pulverization by the kneading and pulverizing blade 70A is performed in a state where the liquid is immersed in the cereal grains, so that the cereal grains can be easily pulverized to the core.

  In Step # 22, in order to obtain a desired pulverized grain, a pulverization pattern as set (however, if the pulverizing blade is continuously rotated, intermittently interlaced with a stop period, or intermittently rotated, the interval is taken. The control device 80 checks whether or not the rotation time length has been completed.

  When the set pulverization pattern is completed, the process proceeds to step # 23, the rotation of the kneading and pulverizing blade 70A is completed, and the pulverization step # 20 is completed. This is notified to the user by display on the display unit 22, voice, or the like.

  In the above description, the pulverization step # 20 is started by the user's operation after the pre-grinding impregnation step # 10. If the pulverization operation data is input in the middle of No. 10, the pulverization step # 20 may be automatically started after the pre-pulverization impregnation step # 10 is completed. Further, if the user presses the start key in the first stage, for example, in the case of the first aspect bread manufacturing process, if the user presses the start key after completing the setting of grain and liquid in the pre-grinding impregnation process # 10, the last baking process is performed. You may comprise so that bread-making work may progress fully automatically to # 50.

  Subsequent to the pulverization step # 20, the kneading step # 30 shown in FIG. 11 is performed. At the time of entering the kneading step # 30, the cereal grains and liquid in the bread container 50 are pasty or slurry dough raw materials. In the present specification, the material at the start of the kneading step # 30 is referred to as “dough raw material”, and the material that has come close to the intended state of the dough as the kneading progresses, ".

  In step # 31, the user opens the lid 30 and puts a predetermined amount of gluten into the dough material. Add seasoning ingredients such as salt, sugar and shortening as needed. The automatic bread maker 1 may be provided with an automatic charging device for gluten and seasoning materials, and the user can input them without bothering the user.

  The user inputs the type of bread and cooking details from the operation unit 20 before and after Step # 31. When the user presses the start key when the preparation is complete, the bread making operation that automatically continues from the kneading step # 30 to the fermentation step # 40 and further to the baking step # 50 is started.

  In step # 32, the control device 80 drives the motor 60 to rotate the blade rotation shaft 52 in the forward direction. Then, the movable blade 73 of the kneading and pulverizing blade 70A is in an upright posture and starts kneading.

  Here, the control device 80 energizes the heating device 41 and raises the temperature of the baking chamber 40. As the kneading and pulverizing blade 70A rotates, the dough raw material is kneaded and kneaded into a dough connected to each other with a predetermined elasticity. The kneading and pulverizing blade 70A shakes the dough and knocks it against the inner wall of the bread container 50, so that an element of “kneading” is added to the kneading. The protrusion 50a formed on the inner wall of the bread container 50 helps "kneading".

  In step # 33, the control device 80 checks how much time has elapsed since the start of kneading. When the predetermined time has elapsed, the process proceeds to step # 34.

  In step # 34, the user opens the lid 30 and puts yeast into the dough. At this time, the yeast used in the dough may be dry yeast. Baking powder may be used instead of yeast. For yeast and baking powder, an automatic dosing device can be used to save the user.

  In step # 35, the control device 80 checks how much time has passed since the yeast was added to the dough. When the time necessary to obtain the desired dough has elapsed, the process proceeds to step # 36, where the rotation of the kneading / pulverizing blade 70A is completed. At this point, the dough that is connected and has the required elasticity has been completed.

  When baking the bread containing ingredients, the ingredients are introduced in any step of the kneading step # 30. An automatic loading device can also be used for material loading.

  Following the kneading step # 30, the fermentation step # 40 shown in FIG. 12 is performed. In step # 41, the dough that has undergone the kneading step 30 is placed in a fermentation environment. That is, the control device 80 energizes the heating chamber 40 to the heating device 41 if necessary, and sets the temperature in a temperature zone where fermentation proceeds. The user arranges the dough, if necessary, and leaves the dough.

  In step # 42, the control device 80 checks how much time has passed since the dough was placed in the fermentation environment. If predetermined time passes, fermentation process # 40 will be complete | finished.

  Subsequent to the fermentation step # 40, the firing step # 50 shown in FIG. 13 is performed. In step # 51, the fermented dough is placed in a baking environment. That is, the control device 80 sends electric power necessary for baking to the heating device 41 and raises the temperature of the baking chamber 40 to the baking temperature zone.

  In step # 52, the control device 80 checks how much time has passed since the dough was placed in the baking environment. When the predetermined time has elapsed, the firing step # 50 ends. Here, since the completion of bread making is notified by display or sound on the display unit 22, the user opens the lid 30 and takes out the bread container 50. And bread is taken out from the bread container 50.

  Next, the second aspect bread making process will be described with reference to FIGS. FIG. 14 is an overall flowchart of the second aspect bread manufacturing process. In FIG. 14, the process proceeds in the order of pulverization step # 20, post-pulverization impregnation step # 60, kneading step # 30, fermentation step # 40, and firing step # 50. Next, the content of the post-grinding impregnation step # 60 will be described based on FIG.

  In step # 61, the dough raw material formed in the pulverization step # 20 is left in the bread container 50. This dough raw material has not been subjected to the impregnation step before pulverization. While standing still, liquid soaks into the ground grain. The control device 80 energizes the heating device 41 as necessary to heat the dough material and promote the impregnation.

  In step # 62, the control device 80 checks how much time has elapsed since the start of standing. When the predetermined time has elapsed, the post-grinding impregnation step # 60 is finished. When the post-grinding impregnation step # 60 is completed, the process automatically proceeds to the kneading step # 30. The steps after the kneading step # 30 are the same as the first aspect bread making step.

  Then, the 3rd aspect bread-making process is demonstrated based on FIG. FIG. 16 is an overall flowchart of the third aspect bread manufacturing process. Here, the pre-pulverization impregnation step # 10 of the first aspect is placed before the pulverization step # 20, and the post-pulverization impregnation step 60 of the second aspect is placed after the pulverization step # 20. The steps after the kneading step 30 are the same as the first aspect bread making step.

  The kneading and pulverizing blade 70A can be used not only for pulverizing cereal grains but also for fragmenting ingredients such as nuts and leafy vegetables. For this reason, bread containing fine ingredients can be baked. The kneading and pulverizing blade 70A can also be used for pulverizing ingredients other than ingredients mixed in bread and herbal raw materials.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The kneading and pulverizing blade 70B used in the second embodiment has a fixed blade 77 at a position where the movable blade 73 is present in the kneading and pulverizing blade 70A of the first embodiment. The fixed blade 77 has a crushing edge 74 formed on the edge that becomes the front edge when the blade rotation shaft 52 rotates in the opposite direction, and the kneading that rises vertically on the edge opposite to the crushing edge 74. The pressing surface 78 is provided. An inclined surface 79 is formed between the crushing edge 74 and the upper end of the kneading pressing surface 78.

  Also in the second embodiment, the blade rotation shaft 52 is rotated in the reverse direction to cause the kneading / pulverization blade 70B to perform pulverization, and the blade rotation shaft is rotated in the forward direction to perform kneading, thereby From crushing to baking bread can be accomplished in a single bread container 50.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  The present invention is widely applicable to automatic bread machines used mainly in general households.
