  In the present embodiment, the first pulley 61 is configured to have a larger diameter than the second to fourth pulleys 62 to 64. Thereby, the rotational speed of the kneading blade 84 with respect to the rotational speed of the output shaft 71 of the inverter motor 70 is reduced (for example, 250 rpm), and a high torque is obtained. Further, the rotational speed of the mill blade 82 relative to the rotational speed of the kneading blade 84 is set to a high speed (for example, 4000 rpm).

  In this embodiment, the “mill shaft” is constituted by a main body side mill shaft 14A and a container side mill shaft 14B which are connected by engaging the main body side connector 17A and the container side connector 17B. . The “kneading shaft” is constituted by a main body side kneading shaft 16A and a container side kneading shaft 16B which are connected by engaging the engaging pieces 16Aa and the engaging pieces 16Ba. Further, the center axis of the mill shaft that is the rotation shaft 205 of the mill blade 82 and the center axis of the kneading shaft that is the rotation shaft 205 of the kneading blade 84 are provided on the same axis.

  In this embodiment, the “driving force switching unit” includes the bearings 12, 67, the first to fourth pulleys 61 to 64, the first and second belts 65 and 66, and the first to third one-way clutches. 68, 15, and 13. The “driving force switching unit” switches the transmission path of the rotational driving force of the motor 70 to the mill shaft and the kneading shaft.

  Next, a preferable shape and the like of the mill blade 82 will be described with reference to FIGS. 8 and 9 to 11. FIG. 8 is a bottom view showing the relative position of the mill blade 82 with respect to the dome-shaped cover 83. 9A is a perspective view of the mill blade 82, and FIGS. 9B and 9C are side views of the mill blade 82.

  As shown in FIG. 8, both end portions of the mill blade 82 are formed not to cut grains but to be ground. Specifically, both end portions of the mill blade 82 are formed to have a ground region 82A having a certain length so as to follow the inner peripheral end portion of the dome-shaped cover 83 in plan view. Thereby, a grain can be efficiently used as a bread-making raw material, and the rotational speed of the mill blade 82 can be reduced. As a result, it is possible to reduce the noise generated when the grain is used as a bread-making material, that is, when milling.

  Moreover, the edge of the both ends of the mill blade | wing 82 is formed in the waveform. Thereby, the contact area of the said edge and a grain can be increased, and the grinding effect of a grain can be improved. Preferably, the edges at both ends of the mill blade 82 are formed in a sine wave shape (a wave shape constituted by a curve). Thereby, it can suppress that a user's finger | toe cuts, when a user touches the mill blade | wing 82. FIG.

  Moreover, the edge of the both ends of the mill blade | wing 82 is comprised so that it may have fixed thickness (for example, 1.5 mm) (namely, it does not have a blade edge | tip). Thereby, it can further suppress that a user's finger | toe cuts, when a user touches the mill blade | wing 82. FIG. Moreover, the contact area of the said edge and a grain grain can be increased, and the grinding effect of a grain grain can be improved. Moreover, the intensity | strength as the whole mill blade | wing 82 is securable. The mill blade 82 may be configured to have a uniform thickness including the edge.

  Further, as shown in FIGS. 10 and 11, both end portions of the mill blade 82 are inclined in opposite directions as viewed from the front. Specifically, the both ends of the mill blade 82 are positioned below the portion positioned on the downstream side (the side that first collides with the rice grains) in the rotational direction of the mill blade 82 than the portion positioned on the upstream side. So as to be inclined. Further, the inclination angle of the both ends of the mill blade 82 with respect to the horizontal plane is larger than the conventional one, for example, 13 degrees. Thereby, a grain can be efficiently used as a bread-making raw material, and the rotational speed of the mill blade 82 can be further reduced. As a result, it is possible to further reduce the noise generated when the grain is used as a bread-making material, that is, when milling.

  In this embodiment, the edges at both ends of the mill blade 82 are formed in a wave shape, but the present invention is not limited to this. For example, the edges at both ends of the mill blade 82 may be curved.

  Next, an example of the flow of the rice grain breadmaking course executed by the automatic breadmaker 1 according to the present embodiment will be described with reference to FIG. FIG. 12 is a schematic diagram illustrating the flow of the bread making course for rice grains executed by the automatic bread maker 1 according to the present embodiment. As shown in FIG. 12, in the rice grain breadmaking course, a water immersion process, a mill process, a cooling process, a kneading (providing) process, a fermentation process, and a baking process are sequentially performed.

  When starting the rice grain breadmaking course, the user performs the following operations.

  First, the user attaches the cap 81 to the container side mill shaft 14B, and fits a part of the safety cover 85 to the inner surface of the container side kneading shaft 16B. Thereby, the blade | wing unit 80 is set in the cooking container 40, as shown in FIG.

  Thereafter, the user puts main ingredients such as rice grains, water, and seasonings (for example, salt, sugar, shortening) into the cooking container 40, and dry yeast, gluten, nuts, etc. that are automatically added during the bread manufacturing process. In the secondary material containers 53 and 54.

  Thereafter, the user sets the cooking container 40 in the baking chamber 30 and closes the opening 204 of the baking chamber 30 with the lid 50. Thereafter, the user selects the bread making course for rice grains by using the operation unit 20, and presses the start key. Thereby, the control part 90 starts control operation | movement of the bread-making course for rice grain which manufactures bread using rice grain as a starting material.

  When the rice grain breadmaking course is started, the water immersion process is started by a command from the control unit 90. The water immersion process is a process for making the rice grains easily pulverized to the core in the subsequent milling process by adding water to the rice grains. In the water immersion process, the stationary state of the main material previously charged in the cooking container 40 is maintained for a predetermined time (30 minutes in this embodiment).

  When a predetermined time elapses from the start of the water immersion process, the water immersion process is terminated by a command from the control unit 90, and the mill process is started. A mill process is a process of grind | pulverizing the rice grain put in the cooking container 40, and manufacturing a bread-making raw material. In the mill process, the control unit 90 controls the inverter motor 70 to rotate the output shaft 71 in the reverse direction, and as described above with reference to FIG. 7, the mill blade 82 in the mixture containing rice grains and water is used. Is rotated (eg, 4000 rpm). Thereby, a rice grain is grind | pulverized.

  The mixture containing the pulverized rice grains and water is discharged into the space outside the dome-shaped cover 83 through the plurality of windows 83 a of the dome-shaped cover 83. Along with this, a mixture containing rice grains and water in the recess 41 of the cooking container 40 is taken into the space inside the dome-shaped cover 83 from an opening 204 (not shown) provided in the safety cover 85. In this way, rice grains are crushed one after another by the mill blades 82, and as a result, a bread-making raw material containing pasty pulverized powder is produced.

  In addition, when the size of the rice grain colliding with the mill blade 82 is large, a loud collision sound is generated. For this reason, the control unit 90 can control the inverter motor 70 to rotate the mill blade 82 at a low speed and then rotate the mill blade 82 at a high speed for a predetermined time (for example, 5 minutes) from the start of the mill process. preferable. Thereby, generation | occurrence | production of the loud collision sound in a mill process can be suppressed.

  When a predetermined time (70 minutes in this embodiment) elapses from the start of the milling process, the milling process is terminated by a command from the control unit 90, and the cooling process is started. The cooling step is a step of lowering the temperature of the bread-making raw material in the cooking container 40 that has been raised by the milling step to a temperature at which the dry yeast actively works (for example, around 30 ° C.). In the cooling process, the control unit 90 stops driving the inverter motor 70.

  When a predetermined time (32 minutes in the present embodiment) elapses from the start of the cooling process, the cooling process is ended by a command from the control unit 90, and the kneading process is started. The kneading step is a step of manufacturing bread dough by adding auxiliary materials such as dry yeast, gluten, and nuts to the bread-making material and kneading them. In the kneading process, the control unit 90 opens the opening / closing plates 53a and 54a to put the auxiliary material into the cooking container 40, and controls the inverter motor 70 to rotate the output shaft 71 in the forward direction. As described above, the kneading blade 84 is rotated at a low speed (for example, 250 rpm) in the mixture containing the bread-making raw material and the auxiliary material. Thereby, the mixture containing the bread-making raw material and the auxiliary material is kneaded, and the bread dough having a predetermined elasticity is manufactured.

  If the kneading blades 84 are continuously rotated at the same speed during the kneading process, particularly in the initial stage of the kneading process in which the kneading of the mixture containing the bread-making raw material and the auxiliary material has not progressed, There is a possibility that the material scatters outside the cooking container 40. For this reason, as shown in FIG. 13, it is preferable that the control unit 90 controls the inverter motor 70 so that the rotation speed of the kneading blades 84 gradually increases as the kneading process proceeds. Thereby, in a kneading process, it can suppress that a bread-making raw material and an auxiliary material scatter to the outer side of the cooking container 40. FIG.

  When a predetermined time (23 minutes in the present embodiment) elapses from the start of the kneading process, the kneading process is terminated by a command from the control unit 90, and the fermentation process is started. A fermentation process is a process of fermenting bread dough. In the fermentation process, the control unit 90 controls the sheath heater 31 to maintain the temperature of the baking chamber 30 at a temperature at which fermentation proceeds (for example, 38 ° C.).

  When a predetermined time (75 minutes in this embodiment) has elapsed from the start of the fermentation process, the fermentation process is terminated by a command from the control unit 90, and the baking process is started. The baking step is a step of baking the fermented dough and baking the bread. In the baking process, the controller 90 controls the sheath heater 31 to raise the temperature of the baking chamber 30 to a temperature suitable for baking (for example, 125 ° C.).

  When a predetermined time (40 minutes in this embodiment) has elapsed from the start of the firing process, the firing process is terminated by a command from the control unit 90. Thereby, all the bread making processes are completed. The completion of all the bread making processes is notified to the user by, for example, a display on the liquid crystal panel of the operation unit 20 or a notification sound.

  According to the automatic bread maker 1 according to this embodiment, since both the mill blade 82 and the kneading blade 84 are rotated by the single inverter motor 70, the conventional automatic bread maker having two motors. Thus, the apparatus can be downsized.

  Further, according to the automatic bread maker 1 according to the present embodiment, the bearings 12 and 67 functioning as the driving force switching unit, the first to fourth pulleys 61 to 64, the first and second belts 65 and 66, Since the first to third one-way clutches 68, 15, 13 are all provided inside the apparatus body 10 and outside the baking chamber 30, it is possible to suppress problems such as clogging of bread-making materials and the like in the respective parts. Can do. Thereby, the transmission path of the rotational driving force of the inverter motor 70 can be switched more reliably.

  Further, according to the automatic bread maker 1 according to the present embodiment, since the inverter motor 70 is used as a motor, the rotational speeds of the mill blade 82 and the kneading blade 84 can be varied. Accordingly, for example, by causing the mill blade 82 to rotate at a low speed for a predetermined time from the start of the mill process, it is possible to suppress the occurrence of a large collision sound in the mill process.

  Further, according to the automatic bread maker 1 according to the present embodiment, depending on the rotation direction of the output shaft 71 of the inverter motor 70, the rotational driving force of the inverter motor 70 is transmitted to the mill shaft or switched to the kneading shaft. Thus, the transmission path of the rotational driving force of the inverter motor 70 can be switched more reliably.

  Further, according to the automatic bread maker 1 according to the present embodiment, the kneading shafts 16A and 16B have a hollow tube structure, and the mill shafts 14A and 14B are provided inside the kneading shaft. Thereby, further miniaturization of the apparatus can be achieved.

  In the above description, the inverter motor is used in an automatic bread maker that performs both milling and kneading, but the present invention is not limited to this. You may use an inverter motor for the general automatic bread machine which only kneads. In this case, since the rotation speed of the kneading blade can be varied, for example, the inverter motor can be controlled so that the rotation speed of the kneading blade gradually increases as the kneading process proceeds. Thereby, it can suppress that a bread-making raw material and an auxiliary material scatter to the outer side of a cooking container.

  The structure of the mounting part of the cooking container 40 of the present embodiment will be specifically described below.

  In the description of the above-described embodiment, the cooking container 40 is described. However, the apparatus of this embodiment has a plurality of types (for example, two types) of cooking containers 40, and the first cooking container 401 is This is a container used when making bread from wheat flour or rice flour, and the second cooking container 402 is a container used when making bread from cereal grains such as rice grains.

  The kneading blades 84 can be attached to and detached from the first cooking container 401, and the mill blades 82 and the kneading blades 84 can be attached to and detached from the second cooking container 402.

  FIG. 13 shows a perspective view of the first cooking container 401, and FIG. 14 shows the first cooking container 401 as viewed from below. FIG. 15 is a partial cross-sectional view of the first cooking vessel 401.

  As shown in FIGS. 14 and 15, the first cooking container 401 has a container-side second rotating body 404 attached to a rotating shaft 403 at the bottom. The container-side second rotating body 404 has a substantially S-shape, and a container-side second engagement portion 405 that protrudes downward is formed at the left and right ends. The two container side second engaging portions 405 are located on substantially the same straight line.

  Although details will be described later, in the state where the first cooking container 401 is disposed in the baking chamber 30, the container-side second rotating body 404 receives the rotational driving force from the motor disposed on the apparatus main body 10 side. Is possible. The container-side second rotating body 404 is connected to the kneading blade 84 disposed in the first cooking container 401, and when the container-side second rotating body 404 rotates, the kneading blade 84 also rotates.

  FIG. 16 shows a perspective view of the second cooking container 402, and FIG. 17 is a view of the second cooking container 402 as viewed from below. FIG. 18 is a partial cross-sectional view of the second cooking vessel 402.

  As shown in FIGS. 17 and 18, the second cooking container 402 has a container-side second rotating body 404 attached to a rotating shaft 406 at the bottom. The container-side second rotating body 404 has a substantially S-shape, and a container-side second engagement portion 405 that protrudes downward is formed at the left and right ends. The two container side second engaging portions 405 are located on substantially the same straight line.

  Although details will be described later, in the state where the second cooking container 402 is disposed in the baking chamber 30, the container-side second rotating body 404 receives the rotational driving force from the motor disposed on the apparatus main body 10 side. Is possible. The container-side second rotating body 404 is connected to the kneading blade 84 disposed in the second cooking container 402, and when the container-side second rotating body 404 rotates, the kneading blade 84 also rotates.

  A container side first rotating body 407 is attached to the rotation shaft 406 of the second cooking container 402, and the container side first rotating body 407 is connected to the mill blade 82. When the container-side first rotating body 407 rotates, the mill blade 82 also rotates.

  Since the container side first rotating body 407 is a rotating body for rotating the mill blade 82, the diameter thereof is smaller than the diameter of the container side second rotating body 404 for rotating the kneading blade 84. By adopting such a configuration, the burden on the rotating body portion and the shaft portion for rotating the rotating body is reduced as compared with the case of increasing the diameter of the rotating body rotating at high speed.

  Three container-side first engagement portions 408 are formed around the rotation shaft 406 in the container-side first rotating body 407. Although details will be described later, in a state where the second cooking container 402 is mounted in the baking chamber 30, the container-side first rotating body 407 receives the rotational driving force from the motor disposed on the apparatus body 10 side. Is possible. As described above, the container-side first rotating body 407 is connected to the mill blade 82 arranged in the second cooking container 402, and when the container-side first rotating body 407 rotates, the mixing blade 84 also rotates.

  FIG. 19 is an exploded perspective view showing the container-side first rotating body 407 and the container-side second rotating body 404 of the second cooking container 402. The container-side first rotating body 407 is formed of an elastic body such as silicon rubber or a metal such as stainless steel. The three container-side first engaging portions 408 formed on the container-side first rotating body 407 have slopes 410 formed from the top 409, and when the second cooking container 402 is attached to the main body. The container side first engagement portion 408 is considered so as to be able to reliably engage with a main body side first engagement portion described later.

  A container-side second engaging portion 405 is positioned on the outer periphery of the container-side first rotating body 407, and the container-side second rotating body 404 including the container-side second engaging portion 405 includes, for example, It is made of metal such as stainless steel. By using stainless steel, it is possible to prevent the container-side second rotating body 404 from rusting when the user washes the cooking container.

  Next, the structure of the bottom part of the firing chamber 30 of the device body 10 will be described below.

  FIG. 20 is a view of the central portion of the baking chamber 30 as viewed from above.

  In FIG. 20, a main body side first rotating body 501 and a main body side second rotating body 502 made of, for example, resin are disposed at the bottom of the baking chamber 30. A main body side second rotating body 502 is disposed below the main body side first rotating body 501, and three main body side first engaging portions 503 are formed on the main body side first rotating body 501. On the other hand, two main body side second engaging portions 504 are formed on the main body side second rotating body 502. Further, as shown in FIG. 20, the main body side second engaging portion 504 is positioned on the outer peripheral side of the main body side first rotating body 501.

  Each of the three main body side first engaging portions 503 is formed with a top and an inclined surface in the same manner as the container side first engaging portion 408 described above, and the second cooking container 402 is attached to the main body. When doing so, the inclined surface 410 of the container side first engaging portion 408 and the inclined surface of the main body side first engaging portion 503 are slidably engaged. By doing in this way, it becomes possible to mount | wear with the 2nd cooking container 402 to a main body reliably.

  As is apparent from FIG. 20, the diameter of the main body side second rotating body 502 is larger than the diameter of the main body side first rotating body 501. Since the main body side first rotating body 501 is a rotating body for rotating the mill blade 82, the rotation speed is higher than that of the main body side second rotating body 502 for rotating the kneading blade 84.

  When a rotating body (rotating shaft) having a large diameter is rotated at a high speed, a large load is applied to the rotating body and the rotating shaft, which may cause a failure. In the apparatus of the present embodiment, in order to avoid such a situation, by making the diameter of the main body side first rotating body 501 rotating at high speed smaller than the diameter of the main body side second rotating body 502 rotating at low speed, The burden on the rotating body and its rotating shaft is reduced as much as possible.

  In this embodiment, the container side second engaging portion 405 of the first cooking container 401 for making bread from the flour and the container side second engaging part 405 of the second cooking container 402 for making bread from the grain. The two engaging portions 405 have different shapes.

  Since the first cooking vessel 401 is not attached with the container-side first rotating body 407, a space for securing the container-side first rotating body 407 is not required. For this reason, the tip of the container-side second engagement portion 405 of the first cooking container 401 is wider than the tip of the container-side second engagement portion 405 of the second cooking container 402.

  Moreover, the front-end | tip of the container side 2nd engaging part 405 of the 1st cooking container 401 and the front-end | tip of the container side 2nd engaging part 405 of the 2nd cooking container 402 become narrow gradually toward the front-end | tip. And has a slope on the surface. In addition, the slope of the inclination is because the container side second engagement portion 405 of the first cooking container 401 is not compared with the container side second engagement portion 405 of the second cooking container 402. .

  Moreover, the 2nd cooking container 402 has a clearance gap between the container side 1st rotary body 407 and the container side 2nd engaging part 405, in order to rotate a container side 1st rotary body.

  Furthermore, the height of the container side second engagement portion 405 of the second cooking container 402 is higher than the height of the container side second engagement portion 405 of the first cooking container 401. The second cooking container 402 is higher in height than the first cooking container 401 in this manner because the container-side first engagement portion 408 of the container-side first rotating body 407 is present.

  In this embodiment, the main body side second rotating body 502 is arranged below the main body side first rotating body 501, but the main body side second rotating body 501 is arranged on the outer peripheral portion of the main body side first rotating body 501. It is good also as a structure which arrange | positions the rotary body 502. FIG. In other words, the main body side first rotating body 501 and the main body side second rotating body 502 may have a structure that does not overlap.

  Next, an operation when the first cooking container 401 is attached to the device main body 10 will be described. When the first cooking container 401 is mounted on the device main body 10, the main body side second engaging portion 504 of the device main body 10 is engaged with the container side second engaging portion 405, and the main body side second rotation is performed by the rotation of the motor. When the body 502 rotates, the rotational force is transmitted to the container-side second rotating body 404 of the first cooking container 401, the kneading blades 84 rotate, and the kneading operation is executed.

  Next, an operation when the second cooking container 402 is attached to the device main body 10 will be described. When the second cooking container 402 is attached to the device main body 10, the main body side second engaging portion 504 of the device main body 10 is engaged with the container side second engaging portion 405, and the main body is rotated by the rotation of the motor during the kneading operation. When the second side rotating body 502 rotates, the rotational force is transmitted to the container side second rotating body 404 of the first cooking container 401, the kneading blades 84 rotate, and the kneading operation is executed.

  In addition, when the second cooking container 402 is attached to the device main body 10, the main body side first engagement portion 503 of the device main body 10 engages with the container side first engagement portion 408. For this reason, during the mill operation, when the main body side first rotating body 501 is rotated by the rotation of the motor, the rotational force is transmitted to the container side first rotating body 407 of the first cooking container 401, and the mill blade 82 rotates, Mill operation is performed.

  Thus, in the apparatus of this example, the main body side first rotating body 501 and the main body side second rotating body 502, which are two different rotating bodies, are arranged at the bottom of the baking chamber. For this reason, it is possible to rotate the mill blade 82 or the kneading blade 84 mounted on the cooking container by rotating one of the two different rotating bodies, and a complicated structure such as a clutch is provided in the cooking container. The rotation of the mill blades 82 and the kneading blades 84 can be realized with a simple structure without them.

  In the apparatus of the present embodiment, the main body side first rotating body 501 and the main body side second rotating body 502 are arranged at the bottom of the baking chamber, and the main body side first rotating body 501 is engaged with the cooking container. The main body side second rotating body 502 has a main body side second engaging portion 504 that engages with the cooking container, and when the bottom of the baking chamber is viewed from above, the main body side first rotating body 502 has the first engaging portion 503. The main body side second engaging portion 504 of the main body side second rotating body 502 is positioned on the outer periphery of the rotating body 501.

  In this manner, the first and second rotating body portions can be compactly combined by bringing the main body side first rotating body 501 and the main body side second rotating body 502 (the second engaging portion 504 thereof) close to each other. It becomes.

  Further, the shaft for high speed rotation that rotates the mill blade 82 is the main body side first rotating body 501 portion, the shaft for low speed rotation that rotates the kneading blade 84 is the second body rotating body 502 portion, and the kneading blade 84 is By causing the main body side second engaging portion 504 of the low speed rotation shaft to rotate (the main body side second rotating body 502 portion) to exist on the outer periphery of the main body side first rotating body 501, the shaft for high speed rotation has a diameter. The shaft for low-speed rotation can be made large in diameter. By realizing the shaft for high-speed rotation with a small diameter in this way, the burden on the rotating body and the shaft portion due to the driving force of the motor can be reduced as much as possible.

  In the apparatus of the present embodiment, the bottoms of the first cooking container 401 and the second cooking container 402 are the part where the container-side first rotating body 407 and the container-side second rotating body 404 are arranged or the vicinity thereof. However, the bottom portion of the portion where the bread ingredients of the first cooking container 401 and the second cooking container 402 are placed may be the bottom.

  The present invention is useful for an automatic bread machine that can be used with a cooking container attached or detached.
