  A first embodiment of the present invention will be described below with reference to the drawings from FIG. 1 to FIG. 1 and 3, the left side of the figure is the front (front) side of the automatic bread maker 1A, and the right side of the figure is the back (rear) side of the automatic bread maker 1A. Further, it is assumed that the left hand side of the observer facing the automatic bread making machine 1A from the front is the left side of the automatic bread making machine 1A, and the right hand side is the right side of the automatic bread making machine 1A.

  The automatic bread machine 1 </ b> A has a box-shaped main body 10. The main body 10 includes a synthetic resin outer shell, and can be transported with a U-shaped synthetic resin handle 11 having both ends connected to the left and right sides thereof.

  An operation unit 20 is formed on the front surface of the main body 10. The operation unit 20 is set with an operation key group 21 such as a selection key for bread types (wheat flour bread, rice flour bread, bread with ingredients), a cooking content selection key, a timer key, a start key, a cancel key, and the like. A display unit 22 for displaying cooking contents, timer reservation time, and the like is provided. The display unit 22 includes 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.

  On the bottom wall 40 b of the baking chamber 40, a bread container support portion 13 made of an aluminum alloy die-cast product is fixed at a position corresponding to the center of the baking chamber 40. The inside of the bread container support portion 13 is exposed to the inside of the baking chamber 40 through an opening formed in the bottom wall 40 b of the baking chamber 40.

  A vertical rotation shaft 14 is supported at the center of the bread container support 13. The lower end of the rotating shaft 14 protrudes from the lower surface of the bread container support part 13, and a pulley 15 is fixed here.

  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 kneading blade 52 is disposed in the center of the bottom of the bread container 50. The kneading blade 52 is attached to the non-circular cross section at the upper end of the vertical rotating shaft 53 supported by taking a sealing measure at the center of the bottom of the bread container 50, and can be attached and detached without using a tool. Can do. For this reason, it can be easily replaced with a different kind of kneading blade 52.

  The rotating shaft 53 is connected to the rotating shaft 14 and transmits power from the rotating shaft 14. As the power transmitting means, a coupling 54 enclosed by a pedestal 51 is used. That is, one of the two members constituting the coupling 54 is fixed to the lower end of the rotating shaft 53, and the other is fixed to the upper end of the rotating shaft 14.

  Protrusions (not shown) are formed on the inner peripheral surface of the bread container support 13 and the outer peripheral surface of the pedestal 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, the coupling 54 is also achieved at the same time. The twisting direction when the bread container 50 is attached coincides with the rotation direction of the kneading blade 52 so that the bread container 50 does not come off even when the kneading blade 52 rotates.

  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 base 12 made of sheet metal is installed inside the main body 10. A motor 60 is attached to the base 12. The motor 60 is a saddle shaft, and the output shaft 61 protrudes from the lower surface. A pulley 63 connected to the pulley 15 of the rotating shaft 14 by a belt 62 is fixed to the output shaft 61.

  In the lid 30, a cylindrical vertical through portion 31 is formed at a position slightly shifted to the right from the center of the bread container 50. Then, the pulverizing unit 70A is inserted into the vertical through portion 31 from above.

  The crushing unit 70A includes a motor case 71 made of synthetic resin. The motor case 71 has a handle 72 on its upper surface and incorporates a saddle shaft motor 73. An annular protrusion 71 a is formed on the upper outer periphery of the motor case 71. The protrusion 71a engages with the upper edge of the vertical penetrating portion 31 and stops further lowering of the motor case 71. When the protrusion 71a stops lowering of the motor case 71, the upper surface of the motor case 71 is covered with a lid. It is almost flush with the upper surface of 30. The horizontal cross-sectional shape of the vertical penetrating portion 31 and the horizontal cross-sectional shape of the motor case 71 are both quadrilaterals, and the pulverizing unit 70A inserted into the lid 30 does not rotate with respect to the lid 30.

  A rotating shaft 75 is connected to an output shaft 74 that protrudes downward from the motor 73. A crushing blade 76 is fixed to the lower end of the rotating shaft 75. A sheath 77 having an upper end fixed to the motor case 71 surrounds the rotating shaft 75 and the grinding blade 76. The sheath 77 is a cylindrical member formed from a sheet metal such as a stainless steel plate. The lower end of the sheath body 77, that is, the portion surrounding the crushing blade 76 is a bulging portion 77a having a diameter larger than that of the other portion and shaped like an inverted tulip flower.

  Concavities and convexities 77b facing the grinding blade 76 are formed on the inner surface of the bulging portion 77a. In the first embodiment, the bulging portion 77a is pushed inward at a predetermined angular interval, thereby forming the unevenness 77b. A horizontal beam 78 is fixed inside the bulging portion 77 a, and a bearing 79 that supports the rotating shaft 75 is attached to the beam 78. In the bulging portion 77a, an air vent hole 77c is formed at a level above the grinding blade 76 (see FIGS. 4 and 5).

  The operation control of the automatic bread maker 1A is performed by the control device 80 shown in FIG. The control device 80 is configured by a circuit board disposed at a proper position in the main body 10 (preferably a portion 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 described so far, a motor The motor driver 81 of 60, the motor driver 82 of the motor 73, and the temperature sensor 83 are 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.

  The motor 73 and the motor driver 82 are connected by a connector 85 that is connected inside the vertical through portion 31. One of the connectors 85 is fixed to the inner surface of the vertical through portion 31, and the other is fixed to the motor case 71. When the motor case 71 is inserted into the vertical through portion 31, the connector 85 is connected.

  Then, the process of manufacturing bread from cereal grains using the automatic bread maker 1A will be described with reference to the drawings from FIG. 10 to FIG. Among them, the first aspect bread manufacturing process is shown in FIGS.

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

  In the pre-grinding impregnation step # 10 shown in FIG. 11, first, in step # 11, the user measures 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 lid 30 is opened to put in and out the bread container 50 or to put grain grains and liquid into the bread container 50 in the baking chamber 40, the crushing unit 70A is pulled out from the lid 30.

  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 baking chamber 40, the lid 30 is closed, and the crushing unit is placed in the vertical through portion 31. Insert 70A. When the crushing unit 70A is inserted until the lowering is stopped by the protrusion 71a, the connector 85 is connected, and the rotary shaft 75 having the crushing blade 76 at the lower end and the sheath 77 surrounding them are provided from the lower surface of the lid 30. It becomes a shape depending on the inside of the bread container 50.

  The kneading blade 52 is directed in a direction that the descending sheath 77 does not hit. Alternatively, the position that does not contact the sheath 77 may be the origin position of the kneading blade 52, and the kneading blade 52 that has finished rotating may be configured to always stop at the origin position.

  In a state where the crushing unit 70 </ b> A is completely inserted into the vertical penetrating portion 31, the lower ends of the crushing blade 76 and the bulging portion 77 a of the sheath body 77 are close to the inner bottom surface of the bread container 50 to a predetermined distance. 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 display unit 22, voice, or the like.

  Following the pre-grinding impregnation step # 10, the pulverization step # 20 shown in FIG. 12 is performed. 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, the grinding is started.

  In step # 21, the controller 80 drives the motor 73 of the crushing unit 70A to rotate the rotating shaft 75. Then, the grinding blade 76 starts rotating in the mixture of the grain and the liquid. Since the pulverization by the pulverization blade 76 is performed in a state where the liquid is immersed in the cereal grains, the cereal grains can be easily pulverized to the core. The unevenness 77b formed on the inner surface of the bulging portion 77a of the sheath body 77 suppresses the flow of the mixture of the grain and the liquid, and promotes pulverization. Since the air vent hole 77c is formed in the bulging portion 77a, no air pool is generated inside the bulging portion 77a. For this reason, the entrance of the mixture of the grain and liquid into the bulging portion 77a is not hindered by the air pool, and the pulverization can be executed steadily.

  Thus, while the grinding blade 76 is rotating, the grains in the bread container 50 enter the bulging part 77a from the gap between the bulging part 77a and the inner bottom surface of the bread container 50 together with the liquid. The pulverization blade 76 repeatedly pulverizes and goes out of the bulging portion 77a, so that the pulverization is continued.

  In step # 22, in order to obtain a desired pulverized grain, a pulverization pattern as set (however, when 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 pulverization pattern as set is completed, the process proceeds to step # 23 to finish the rotation of the pulverization blade 63, and the pulverization step # 20 ends. 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.

  Subsequent to the pulverization step # 20, the kneading step # 30 shown in FIG. 13 is performed. Prior to that, the user pulls out the crushing unit 70A from the lid 30 and inserts a dummy plug 90 as a substitute for the crushing unit 70A into the vertical penetrating portion 31 as shown in FIGS. The dummy plug 90 has the same dimensions as the motor case 71, and a handle 91 is provided on the upper surface.

  If the kneading blade 52 rotates while the sheath body 77 is suspended in the bread container 50, the kneading blade 52 collides with the sheath body 77. Therefore, a detection means for detecting the presence of the sheath body 77 in the bread container 50 is provided, and the motor 60 cannot be driven while the detection means detects the presence of the sheath body 77. Good.

  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 inputs a predetermined amount of gluten into the dough material. Add seasoning ingredients such as salt, sugar and shortening as needed.

  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. Then, the kneading blade 52 starts rotating in the dough material. Further, the controller 80 energizes the heating device 41 and raises the temperature of the baking chamber 40. As the kneading blade 52 rotates, the dough raw material is kneaded and kneaded into a dough connected to one having a predetermined elasticity. When the kneading blade 52 swings the dough and knocks it against the inner wall of the bread container 50, 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 the rotation of the kneading blade 52. 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.

  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 blade 52 is completed. At this point, the dough that is connected and has the required elasticity has been completed.

  In addition, the dry yeast may be sufficient as the yeast used in the dough in step # 34. Baking powder may be used instead of yeast.

  Following the kneading step # 30, the fermentation step # 40 shown in FIG. 14 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. 15 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.

  Then, the 2nd aspect bread-making process is demonstrated based on FIG. 16 and FIG. FIG. 16 is an overall flowchart of the second aspect bread manufacturing process. In FIG. 16, 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 with reference to 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. 18 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 crushing unit 70A can be used not only for crushing grain grains but also for fragmenting ingredients such as nuts and leafy vegetables. For this reason, bread containing fine ingredients can be baked. The crushing unit 70A can also be used for crushing ingredients other than ingredients mixed in bread and crude drug ingredients.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Note that, in the second embodiment, the same reference numerals as those used in the first embodiment are assigned to components that are the same as or in common with those of the first embodiment, and description thereof is omitted.

  The automatic bread maker 1B of the second embodiment is different from the automatic bread maker 1A of the first embodiment in the configuration of the crushing unit. That is, the automatic bread machine 1B uses a crushing unit 70B in which a motor 73 is built in the lid 30 instead of the crushing unit 70A that can be pulled out from the lid 30.

  In the crushing unit 70B, the rotating shaft 75, the crushing blade 76, and the sheath body 77 constitute a crushing blade assembly 90 that is detachably connected to the motor 73. Further, the lid 30 is configured not only to rotate in the vertical plane with the hinge shaft as a fulcrum, but also to raise the fulcrum position itself, that is, lift up.

  A lift-up column 91 shown in FIG. 24 is provided on the back surface of the main body 10 for lifting the lid 30. The lift-up column 91 is accommodated in a sheath-like guide 92 attached to the back surface of the main body 10 and moves in the vertical direction. As a power source for the vertical movement of the lift-up column 91, human power may be used, or a motor or an air cylinder may be used.
