Description

  The present invention relates to an automatic bread maker mainly used in general households.

  A commercially available automatic bread maker for home use generally has a mechanism for producing bread by directly using a bread container into which bread ingredients are placed (see, for example, Patent Document 1). In such an automatic bread maker, first, a bread container in which bread ingredients are placed is placed in a baking chamber in the main body. And the bread raw material in a bread container is kneaded into bread dough with the kneading blade provided in a bread container (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, and the bread container is used as a baking mold to bake the bread (baking process).

  When bread is manufactured using such an automatic bread maker, so far, flour (wheat flour, rice flour, etc.) or flour such as wheat or rice is used as the raw material for bread. It was necessary to have a mixed powder in which various auxiliary materials were mixed. However, in general households, as represented by rice grains, grains are sometimes held in the form of grains instead of in the form of flour. For this reason, it would be very convenient if the automatic bread maker had a mechanism for producing bread directly from grains. With this in mind, the present applicants have developed a bread production method for producing bread using cereal grains as a starting material (see Patent Document 2).

  In this bread manufacturing method, first, cereal grains and a liquid are mixed, and a pulverizing blade is rotated in the mixture to pulverize the cereal grains (grinding step). And the bread raw material containing the paste-form ground powder obtained through the grinding process is kneaded into bread dough using a kneading blade (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, followed by a baking process for baking the bread.

  The present applicants are working on the development of an automatic bread maker having a new mechanism capable of executing the above-described method for producing bread using the grain as a starting material. As a configuration of the automatic bread maker provided with this new mechanism, for example, a configuration in which the baking process can be executed from the above-described crushing process in a bread container accommodated in a baking chamber provided in the main body is considered. .

  More specifically, a configuration in which the grinding function and the kneading function are appropriately exhibited by the rotation of one rotating shaft (blade rotating shaft) disposed at the bottom of the bread container is considered. In this configuration, when the bread container is accommodated in the baking chamber, a coupling for transmitting the rotation of the motor (provided in the main body) to the blade rotation shaft is required. This coupling includes, for example, a main body side connecting portion provided at the upper end of a driving shaft (a rotating shaft disposed in the main body and rotating by driving a motor in the main body), and a container provided at the lower end of the blade rotating shaft. And a side connection portion.

  However, the automatic bread maker adopting the above-described coupling has the following problems. That is, in the pulverization process for pulverizing grain grains and the kneading process for kneading bread dough, force is easily applied to the bread container housed in the baking chamber. As a result, there is a problem that the bread container is lifted from the predetermined set position, and the power transmission by the coupling becomes unstable.

  In this regard, with reference to a conventional automatic bread maker (see, for example, Patent Document 2), when the bread container is accommodated in the baking chamber, a bayonet connection is obtained between the bread container and the main body, It is conceivable to prevent the bread container from moving (raising) during the bread manufacturing process. When this configuration is adopted, usually the direction of twisting of the bread container (to obtain bayonet coupling) when the bread container is accommodated in the baking chamber so that the bread container is not detached from the main body by rotation of the blade rotation shaft. Adjust the rotation axis of the blade to the direction of rotation.

  However, in adopting a configuration in which the pulverization function and the kneading function are appropriately exhibited using one blade rotation shaft, the applicant of the present invention has obtained the blade rotation shaft when obtaining the pulverization function and when obtaining the kneading function. It is considered to adopt a configuration in which the rotation directions are opposite to each other. In this case, even if the above-described bayonet coupling is employed, in either case of the grinding process and the kneading process, the bread container moves (floats) and the power transmission by the coupling becomes unstable. Will occur.

  Further, in an automatic bread maker in which a bread container is received in the baking chamber and the bread manufacturing process is executed, the orientation (accommodating direction) of the bread container when the bread container is stored (set) in the baking chamber is determined. It is often done. For this reason, if a bread container can be easily set in a baking chamber according to this accommodation direction, the automatic bread maker will be convenient for the user, which is preferable. This problem is not limited to an automatic bread maker that can bake bread using cereal grains as a starting material, but also to a conventional automatic bread maker that bakes bread using cereal flour (such as wheat flour or rice flour) as a starting material. This is also true.

  In view of the above points, an object of the present invention is to provide an automatic bread maker that can easily place a bread container at a set position in a baking chamber. Another object of the present invention is to provide an automatic bread maker in which a bread container can be easily placed at a set position in a baking chamber and the bread container accommodated in the baking chamber is difficult to move during the bread manufacturing process. . Furthermore, another object of the present invention is an automatic bread maker equipped with a convenient mechanism for baking bread from cereal grains, wherein the bread container can be easily placed at a set position in the baking chamber and the bread contained in the baking chamber. It is to provide an automatic bread maker where the container is difficult to move during the bread making process.

  In order to achieve the above object, the automatic bread maker of the present invention is an automatic bread maker in which a bread container into which bread ingredients are charged is received in a baking chamber in the main body, and a bread manufacturing process is executed. The bread container side guide portion provided on the outer surface of the bread container and the bread container side guide portion provided on the inner surface of the baking chamber and when the bread container is received in the baking chamber. A main body side guide portion that engages with the bread container side guide portion and guides the bread container to a set position at a time near the upper end of the main body.

  In this configuration, when the bread container is disposed at the set position in the baking chamber, the bread container reaches the set position while being guided by the guide portions (two of the bread container side guide portion and the main body side guide portion). For this reason, it is easy to set the bread container in the baking chamber. When the bread container is received in the baking chamber, the main body side guide portion is engaged with the bread container side guide portion when the bread container side guide portion is in the vicinity of the upper end of the baking chamber. For this reason, the user can implement | achieve easily, confirming the engagement between two guide parts visually. Therefore, according to this structure, the user can arrange | position a bread container smoothly in the setting position of a baking chamber.

  In the automatic bread maker configured as described above, a pedestal is provided at the bottom on the outer surface side of the bread container, a bread container support part for receiving the pedestal is provided at the bottom of the baking chamber, and the main body side guide part is The base is provided so that the pedestal does not reach the bread container support part when the bread container side guide part starts engaging with the main body side guide part. According to this configuration, the bread container can be accommodated in the baking chamber by appropriately positioning the pedestal and the bread container support part by the main body side guide part and the bread container side guide part. That is, it is possible to avoid a situation in which the pedestal is caught by any part of the baking chamber and cannot be moved while the bread container is housed in the baking chamber. For this reason, the user can easily set the bread container in the baking chamber.

  In the automatic bread maker configured as described above, the bread container side guide part and the main body side guide part function to fix the bread container in cooperation with the bread container disposed at the set position. It is preferable to exert. According to this configuration, it is possible to prevent the bread container from moving in the baking chamber during execution of the bread manufacturing process. For this reason, according to this structure, bread can be manufactured stably.

  In the automatic bread maker configured as described above, the bread container side guide portion has an engagement groove extending in a direction in which the bread container is received in the baking chamber, and the main body side guide portion is formed from an inner surface of the baking chamber. It is good also as having an engaging protrusion part which protrudes and engages with the said engaging groove. According to this configuration, it is easy to obtain a configuration in which the guide portion exhibits two functions such as guiding the bread container and fixing the bread container.

  In the automatic bread maker configured as described above, the main body side guide portion includes a plate-like fixing portion attached to the inner surface of the baking chamber, and a protruding piece portion that is folded back with respect to the fixing portion. The projecting piece portion may be the engagement projecting portion. In this configuration, the protruding piece portion may be provided with a bent portion that increases an inclination angle with respect to the fixed portion.

  More specifically, the projecting piece portion has a smaller inclination angle of the projecting piece portion with respect to the fixed portion on the front side in the receiving direction when the bread container is received in the baking chamber, and a position before the bread container reaches the set position. It is preferable that the protrusion is bent so that the inclination angle of the projecting piece with respect to the fixed portion becomes large. With this configuration, the bread container can be smoothly accommodated in the baking chamber, and a sufficient force can be obtained for fixing the bread container when the bread container reaches the set position.

  In the automatic bread maker configured as described above, it is preferable that the engagement groove extends to the vicinity of the upper end of the bread container. According to this configuration, since the engagement range of the engagement groove and the engagement protrusion can be widened, the bread container can be stably guided using the bread container side guide part and the main body side guide part.

  In the automatic bread maker configured as described above, a rotating shaft provided at the bottom of the bread container, a grinding blade and a kneading blade rotatable by rotation of the rotating shaft, a motor provided in the main body, and a baking chamber A coupling that transmits the rotational force of the motor to the rotating shaft of the accommodated bread container, and when the rotating shaft is rotated in one direction by the motor, the grinding function by the grinding blade is The kneading function by the kneading blade may be obtained when the rotation shaft is rotated in the direction opposite to the one direction by the motor.

  According to this structure, it is possible to manufacture bread using cereal grains as a starting material. Further, since it is possible to switch between the crushing function and the kneading function in the automatic bread maker only by switching the rotation direction of the rotating shaft, the control operation in the automatic bread maker is not complicated. In addition, since the pan container is fixed using the guide portion, the rotation direction of the rotation shaft is switched. However, the disadvantage as in the case of using bayonet coupling does not occur.

  In the automatic bread maker configured as described above, a flange is formed on the opening side edge of the bread container, and a handle member is attached to the flange so as to be able to stand upside down and the handle member is laid sideways. In this state, a part of the handle member may be in contact with a portion protruding from the collar portion of the stopper for fixing the bread container side guide portion. According to this configuration, when performing an operation of moving the handle member from the standing state to the sideways state, it is possible to prevent the portion of the handle member that has fallen from contacting the container body. That is, according to this structure, it can suppress that a bread container main body is damaged.

  According to the present invention, it is possible to provide an automatic bread maker that can easily place a bread container at a set position in a baking chamber. In addition, according to the present invention, it is possible to provide an automatic bread maker in which a bread container can be easily accommodated in a set position in a baking chamber and the bread container accommodated in the baking chamber is difficult to move during the bread manufacturing process. Furthermore, according to the present invention, an automatic bread maker having a convenient mechanism for baking bread from grain grains, the bread container can be easily accommodated in the set position in the baking chamber, and the bread container accommodated in the baking chamber is the bread container. It is possible to provide an automatic bread maker that does not easily move during the manufacturing process. For this reason, according to the present invention, it is expected that home bread making will become popular by making home bread production more familiar.

In addition, the specific time, temperature, etc. which appear in this specification are illustrations to the last, and they do not limit the content of this invention.
(Configuration of automatic bread maker)
FIG. 1 is a schematic perspective view showing an external configuration of the automatic bread maker according to the present embodiment. As shown in FIG. 1, an operation unit 20 is provided on a part of the upper surface of a main body 10 (the outer shell of which is formed of, for example, metal or synthetic resin) of an automatic bread maker 1 provided in a substantially rectangular parallelepiped shape. It has been. The operation unit 20 includes an operation key group and a display unit that displays time, contents set by the operation key group, errors, and the like. The operation key group includes, for example, a start key, a cancel key, a timer key, a reservation key, a bread manufacturing course (a course for manufacturing bread using rice grains as a starting material, a course for manufacturing bread using rice flour as a starting material) And a selection key for selecting a course for producing bread using flour as a starting material. The display unit is configured by, for example, a liquid crystal display panel.

  Inside the main body 10 is provided a baking chamber 30 in which a bread container 80, which will be described in detail later, is accommodated. The firing chamber 30 is a box-shaped chamber having a substantially rectangular shape, which includes a bottom wall 30a made of, for example, sheet metal and four side walls 30b (see also FIG. 4 described later), and an upper surface thereof is open. The firing chamber 30 can be opened and closed by a lid 40 provided on the upper part of the main body 10. The lid 40 is attached to the back side of the main body 10 with a hinge shaft (not shown), and the firing chamber 30 can be opened and closed by rotating about the hinge shaft as a fulcrum. FIG. 1 shows a state where the lid 40 is opened.

  The lid 40 is provided with a viewing window 41 made of, for example, heat-resistant glass so that the inside of the baking chamber 30 can be seen. A bread ingredient storage container 42 is attached to the lid 40. This bread ingredient storage container 42 makes it possible to automatically feed some bread ingredients during the bread production process. The bread raw material storage container 42 includes a box-shaped container body 42a having a substantially rectangular plane shape, and a container lid 42b that is provided so as to be rotatable with respect to the container body 42a and opens and closes the opening of the container body 42a. . Further, the bread ingredient storage container 42 can support the container lid 42b from the outer surface (lower surface) side and maintain the closed state of the opening of the container body 42a, and is moved by an external force to move the container lid 42b to the container lid 42b. There is also provided a movable hook 42c for releasing the engagement.

  An automatic closing solenoid 16 (see FIG. 14 to be described later) is provided in the main body 10 on the lower side of the operation unit 20, and when the automatic closing solenoid 16 is driven, the plunger is adjacent to the lid 40. It protrudes from the opening 10b provided in the wall surface 10a. Then, a movable member (not shown) movable by the protruding plunger moves the movable hook 42c, the container lid 42b and the movable hook 42c are disengaged, and the container lid 42b rotates. As a result, the opening of the container body 42a is opened. Note that FIG. 1 shows a state where the opening of the container main body 42a is opened.

  The container main body 42a and the container lid 42b are preferably provided with a metal such as aluminum so that a powder bread raw material (for example, gluten, dry yeast, etc.) stored in the container does not remain in the container. And it is preferable that those inner surfaces are covered with a coating layer of silicon, fluorine, or the like, and further, unevenness is not provided as much as possible and it is preferably formed smoothly.

  Further, if steam generated when pulverizing grains such as rice grains enters the container main body 42a, the bread material tends to adhere to the inner surface of the container, which is not preferable. For this purpose, a flange (flange) is provided on the opening side edge of the container main body 42a so that the above-described steam or the like does not enter the container main body 42a, and the container main body 42a is provided between the flange and the container lid 42b. Is provided with a packing (seal member) 42d.

  FIG. 2 is a schematic diagram for explaining the internal configuration of the main body of the automatic bread maker according to the present embodiment. FIG. 2 assumes a case where the automatic bread maker 1 is viewed from above, and the lower side of the figure is the front side of the automatic bread maker 1 and the upper side of the figure is the back side. As shown in FIG. 2, in the automatic bread maker 1, a low-speed / high-torque type kneading motor 50 used in the kneading process is fixedly disposed on the right side of the baking chamber 30, and the grinding process is performed behind the baking chamber 30. The high-speed rotation type crushing motor 60 used in the above is fixedly arranged. The kneading motor 50 and the crushing motor 60 are both shafts.

  A first pulley 52 is fixed to an output shaft 51 protruding from the upper surface of the kneading motor 50. The first pulley 52 is connected by a first belt 53 to a second pulley 55 having a diameter larger than that of the first pulley 52 and fixed to the upper side of the first rotating shaft 54. Has been. A second rotating shaft 57 is provided on the lower side of the first rotating shaft 54 so that the center of rotation thereof is substantially the same as the first rotating shaft 54 (see also FIG. 3 described later). The first rotating shaft 54 and the second rotating shaft 57 are rotatably supported inside the main body 10. In addition, a clutch 56 that performs power transmission and power interruption is provided between the first rotation shaft 54 and the second rotation shaft 57 (see also FIG. 3 described later). The configuration of the clutch 56 will be described later.

  A third pulley 58 is fixed to the lower side of the second rotating shaft 57 (see also FIG. 3 described later). The third pulley 58 is provided on the lower side of the firing chamber 30 by the second belt 59 and is fixed to the driving shaft 11 and has a first driving shaft pulley 12 (having substantially the same diameter as the third pulley 58). (See FIG. 3 described later). The kneading motor 50 itself is a low speed / high torque type, and the rotation of the first pulley 52 is decelerated and rotated by the second pulley 55 (for example, decelerated to 1/5 speed). For this reason, when the kneading motor 50 is driven in a state where the clutch 56 transmits power, the driving shaft 11 rotates at a low speed.

  The first pulley 52, the first belt 53, the first rotating shaft 54, the second pulley 55, the clutch 56, the second rotating shaft 57, the third pulley 58, the second belt 59, and Hereinafter, the power transmission unit configured by the first driving shaft pulley 12 may be expressed as a first power transmission unit PT1.

  A fourth pulley 62 is fixed to the output shaft 61 protruding from the lower surface of the grinding motor 60. The fourth pulley 62 is fixed by a third belt 63 below the second driving shaft pulley 13 (below the first driving shaft pulley 12) fixed to the driving shaft 11; 3). The second driving shaft pulley 13 has substantially the same diameter as the fourth pulley 62. A grinding motor 60 that can rotate at high speed is selected. Since the rotation of the fourth pulley 62 is maintained at substantially the same speed in the second driving shaft pulley 13, the driving shaft 11 rotates at a high speed (for example, 7000 to 8000 rpm) by the high speed rotation of the grinding motor 60. Do.

  In the following, the power transmission unit configured by the fourth pulley 62, the third belt 63, and the second driving shaft pulley 13 may be expressed as a second power transmission unit PT2. . The second power transmission unit PT2 has a configuration that does not have a clutch, and connects the output shaft 61 of the crushing motor 60 and the driving shaft 11 so that power can be transmitted constantly.

  FIG. 3 is a view for explaining a clutch included in the first power transmission unit provided in the automatic bread maker of the present embodiment. FIG. 3 is a diagram assuming the case of viewing along the direction of arrow X in FIG. 3A shows a state in which the clutch 56 performs power cut-off, and FIG. 3B shows a state in which the clutch 56 performs power transmission.

  As shown in FIG. 3, the clutch 56 includes a first clutch member 561 and a second clutch member 562. When the claw 561a provided on the first clutch member 561 and the claw 562a provided on the second clutch member 562 are engaged with each other (the state shown in FIG. 3B), the clutch 56 transmits power. Further, when the two claws 561a and 562b are not engaged with each other (the state shown in FIG. 3A), the clutch 56 cuts off the power. That is, the clutch 56 is a meshing clutch.

  In the present embodiment, each of the two clutch members 561 and 562 has a circumferential direction (when the first clutch member 561 is seen in plan view from below, or the second clutch member 562 is seen in plan view from above. Assuming the case), six claws 561a and 562a arranged at almost equal intervals are provided, but the number of the claws may be appropriately changed. Moreover, what is necessary is just to select a preferable shape suitably for the shape of nail | claw 561a and 562a.

  The first clutch member 561 is attached to the first rotating shaft 54 so as to be slidable in the axial direction (vertical direction in FIG. 3) and not to be relatively rotatable, after taking measures against slipping off. Yes. A spring 71 is loosely fitted on the upper side of the first clutch member 561 of the first rotating shaft 54. The spring 71 is disposed so as to be sandwiched between a stopper portion 54a provided on the first rotating shaft 54 and the first clutch member 561, and biases the first clutch member 561 downward. ing. On the other hand, the second clutch member 562 is fixed to the upper end of the second rotating shaft 57.

  Switching between the power transmission state and the power cut-off state in the clutch 56 is performed using an arm portion 72 that can be selectively arranged at the lower position and the upper position. A part of the arm portion 72 is disposed below the first clutch member 561 and can come into contact with the outer peripheral side of the first clutch member 561.

  The arm unit 72 is driven using a clutch solenoid 73. The clutch solenoid 73 includes a permanent magnet 73a and is a so-called self-holding solenoid. The plunger 73 b of the clutch solenoid 73 is fixed to the plunger fixing attachment portion 72 a of the arm portion 72. For this reason, the arm part 72 moves according to the movement of the plunger 73b in which the amount of protrusion from the housing 73c varies due to the application of voltage.

  When the arm portion 72 moves from the lower position (the state shown in FIG. 3B) to the upper position (the state shown in FIG. 3A), the first clutch member 561 is pushed by the arm portion 72 and attached with the spring 71. Moves up against the forces. When the arm portion 72 is in the upper position, the first clutch member 561 and the second clutch member 562 do not mesh with each other. That is, when the arm portion 72 is in the upper position, the clutch 56 performs power interruption.

  On the other hand, when the arm portion 72 moves from the upper position to the lower position, the first clutch member 561 moves downward while being pushed by the urging force of the spring 71. When the arm portion 72 is in the lower position, the first clutch member 561 and the second clutch member 562 are engaged with each other. That is, when the arm portion 72 is in the lower position, the clutch 56 transmits power.

  When the grinding motor 60 is driven, if the clutch 56 is in a state where power is transmitted (the state shown in FIG. 3B), rotational power for rotating the driving shaft 11 at high speed is transmitted to the output shaft 51 of the kneading motor 50. (See FIG. 2). In this case, if the crushing motor 60 is rotated at, for example, 8000 rpm, the output shaft 51 of the kneading motor 50 is rotated at 40000 rpm depending on the radius ratio (for example, 1: 5) between the first pulley 52 and the second pulley 55. The power to make it necessary. As a result, a very large load is applied to the pulverization motor 60, and the pulverization motor 60 may be damaged. For this reason, when driving the grinding motor 60, it is necessary to prevent the rotational power for rotating the driving shaft 11 from being transmitted to the output shaft 51 of the kneading motor 50. Thus, as described above, the automatic bread maker 1 includes the clutch 56 that performs power transmission and power interruption in the first power transmission unit PT1.

  As described above, in the automatic bread maker 1, the second power transmission unit PT2 is not provided with a clutch. This is due to the following reason. That is, even if the kneading motor 50 is driven, the driving shaft 11 is only rotated at a low speed (for example, 180 rpm). For this reason, even if the rotational power for rotating the driving shaft 11 is transmitted to the output shaft of the crushing motor 60, a large load is not applied to the kneading motor 50. And the manufacturing cost of the automatic bread maker 1 is suppressed by adopting the structure in which the clutch is not provided in the second power transmission part PT2 in this way. However, it goes without saying that a configuration in which a clutch is provided in the second power transmission unit PT2 may be adopted.

  FIG. 4 is a diagram schematically showing the configuration of the baking chamber in which the bread container is accommodated and its surroundings in the automatic bread maker of the present embodiment. FIG. 4 assumes a configuration when the automatic bread maker 1 is viewed from the front side, and the configurations of the baking chamber 30 and the bread container 80 are generally shown in cross-sectional views. FIG. 5 is a schematic plan view of the automatic bread maker (with the lid open) of this embodiment as viewed from above. In addition, the bread container 80 used as a baking mold while the bread raw material is charged can be freely inserted into and removed from the baking chamber 30, and FIG. 5 illustrates a state where the bread container 80 is removed from the baking chamber 30. FIG.

  As shown in FIGS. 4 and 5, a sheathed heater 31 (an example of a heating unit) is disposed inside the baking chamber 30 so as to surround the bread container 80 accommodated in the baking chamber 30. By using this sheathed heater 31, it is possible to heat the bread ingredients (including the dough) in the bread container 80.

  Further, a main body side guide portion 32 is provided near the upper end portion of two opposing side walls 30b (two side walls opposing in the longitudinal direction) of the baking chamber 30. This opposite side guide part 32 cooperates with the bread container side guide part 84 (refer FIG. 4) mentioned later for details, and while the bread container 80 is smoothly accommodated in the baking chamber 30, a bread container Also plays the role of fixing 80. 6A and 6B are schematic views showing the configuration of the main body side guide portion provided in the baking chamber of the automatic bread maker according to the present embodiment. FIG. 6A is a side view, and FIG. FIG. 6C is a perspective view when viewed obliquely from below.

  The main body side guide portion 32 is a plate-like fixing portion 321 that is a portion attached to the inner surface side of the side wall 30 b constituting the baking chamber 30, and is folded back with respect to the fixing portion 321 and protrudes toward the inside of the baking chamber 30. And a projecting piece 322 (corresponding to the engaging projection of the present invention). The main body side guide portion 32 is obtained integrally, for example, by bending a sheet metal, and also exhibits a function as a leaf spring member.

  The fixing portion 321 is provided with screw fixing holes (screw holes 323) at two locations, and in the present embodiment, the main body side guide portion 32 is fixed to the side wall 30b using screws. It has become. However, the fixing method of the main body side guide portion 32 to the side wall 30b may of course be a method other than screwing, and if a method other than screwing is adopted, the screw hole 323 is not necessary. The main body side guide portion 32 is fixed so that the upper end portion thereof is positioned in the vicinity of the upper end portion of the baking chamber 30. The folding piece 326 provided at the lower end of the fixing portion 321 is used for positioning when the main body side guide portion 32 is attached to the side wall 30b, and may be erased in some cases.

  A through hole 324 is formed above and below the projecting piece 322. This is so that when the main body side guide portion 32 is fixed to the side wall 30b using a screw, a screw is inserted from the inside of the firing chamber 30 and can be screwed. The through hole 324 may not be provided as appropriate.

  A first bent portion 322a, a second bent portion 322b, and a third bent portion 322c are formed on the protruding piece portion 322 in order from the top to the bottom. The first bent part 322a reduces the inclination angle (projection amount) of the protruding piece part 322 with respect to the fixed part 321. The second bent portion 322b increases the inclination angle (projection amount) of the protruding piece portion 322 with respect to the fixed portion 321. For this reason, the protrusion piece 322 has a shape in which the upper side from the middle substantially protrudes less than the fixed part 321 and the lower side from the middle largely protrudes from the fixed part 321 in a side view. The third bent portion 322c is bent in a direction to reduce the inclination angle (projection amount) of the protruding piece portion 322 with respect to the fixed portion 321 and is provided in consideration of safety and the like.

  An auxiliary protruding piece 325 that protrudes toward the protruding piece portion 322 toward the lower side is formed on the lower side of the fixing portion 321 approximately from the middle. The auxiliary protruding piece 325 reinforces the elastic force of the protruding piece portion 322, but it does not necessarily have to be provided.

  Referring to FIGS. 4 and 5, a bread container support portion 14 (for example, made of an aluminum alloy die-cast product) that supports the bread container 80 is fixed at a position that is approximately the center of the bottom wall 30 a of the baking chamber 30. Has been. The bread container support portion 14 is formed so as to be recessed from the bottom wall 30a of the baking chamber 30, and the shape of the recess is substantially circular when viewed from above. Four engagement grooves 14a are formed on the inner wall of the bread container support portion 14 so as to be arranged at substantially equal intervals in the circumferential direction. The driving shaft 11 is supported at the center of the bread container support portion 14 so as to be substantially perpendicular to the bottom wall 30a. A main body side connecting portion 11 a is fixed to the upper end of the driving shaft 11.

  FIG. 7 is a schematic diagram showing the configuration of the bread container provided in the automatic bread maker of the present embodiment, FIG. 7 (a) is a side view, FIG. 7 (b) is a perspective view seen from diagonally above, FIG. c) is a perspective view seen obliquely from below. Hereinafter, the configuration of the bread container 80 will be described mainly with reference to FIGS. 4 and 7. The bread container 80 is, for example, a die-cast molded product of aluminum alloy (others may be made of sheet metal or the like), and has a bucket-like shape. On the opening side edge of the bread container 80 (in other words, “the upper end of the bread container 80 surrounds the opening”), a flange 80a is formed. A handle 85 for a handbag that is supported so as to be pivotable and can be laid up and down is attached to the collar portion 80a. The horizontal cross section of the bread container 80 is a rectangle with rounded corners. Further, a concave portion 81 having a substantially circular shape in a plan view is formed on the bottom of the bread container 80 so as to accommodate a part of a blade unit 90 which will be described in detail later.

  At the center of the bottom of the bread container 80, a blade rotation shaft 82 (an example of the rotation shaft of the present invention) extending in the vertical direction is rotatably supported in a state where measures against sealing are taken. A container-side connection portion 82a is fixed to the lower end of the blade rotation shaft 82 (projecting outward from the bottom of the bread container 80).

  Further, a cylindrical base 83 is provided on the outer surface side of the bottom of the bread container 80 so as to surround the blade rotation shaft 82. The bread container 80 is accommodated (arranged in the set position) in the baking chamber 30 in a state where the pedestal 83 is received by the bread container support portion 14. The pedestal 83 may be formed separately from the bread container 80 or may be formed integrally with the bread container 80.

  On the outer surface of the pedestal 83, four engagement protrusions 83a are formed that are arranged at substantially equal intervals in the circumferential direction. The bread container 80 is lowered in position by adjusting the position so that the engagement protrusion 83a of the base 83 fits into the engagement groove 14a of the bread container support portion 14, and thereby the horizontal direction (a plane direction substantially perpendicular to the blade rotation shaft 82). ) Is attached to the baking chamber 30 in a state where the positioning is performed.

  In addition, the circumferential width of the engaging protrusion 83a is formed to be approximately the same size as the circumferential width of the corresponding engaging groove 14a (slightly smaller than the engaging groove 14a). The engaging grooves 14a and the engaging protrusions 83a may be provided so as to be positioned, and the number and size thereof can be changed as appropriate. Further, an engagement protrusion may be provided on the inner wall of the bread container support portion 14, and an engagement groove may be provided on the base 83 of the bread container 80.

  When the bread container 80 is received in the baking chamber 30 in a state where the pedestal 83 of the bread container 80 is received by the bread container support portion 14, the container side connection portion 82 a provided at the lower end of the blade rotation shaft 82, and the driving force Connection with the main body side connection portion 11a fixed to the upper end of the shaft 11 is obtained (see FIG. 4). As a result, the blade rotation shaft 82 can transmit the rotational power from the driving shaft 11. That is, the main body side connecting portion 11a and the container side connecting portion 82a constitute a coupling CP (an example of the coupling of the present invention).

  Moreover, the bread container side guide part 84 is provided in each outer surface of the two side walls (side wall which opposes a longitudinal direction) which the bread container 80 opposes. The bread container side guide portion 84 cooperates with the main body side guide portion 32 (see, for example, FIG. 4) so that the bread container 80 is smoothly accommodated in the baking chamber 30 and fixes the bread container 80. It also plays a role.

  The bread container side guide portion 84 is formed integrally, for example, by bending a sheet metal. In this embodiment, the bread container side guide portion 84 is fixed to the bread container 80 by using a stopper such as a screw or a rivet. Of course, other methods may be used for fixing the bread container guide portion 84 to the bread container 80. The bread container side guide portion 84 extends in a direction (vertical direction) in which the bread container 80 is received in the baking chamber 30, and engages with the projecting portion 322 of the main body side guide portion 32 (the engagement groove of the present invention). Is an example).

  The position of the engagement groove 841 in the vertical direction is not particularly limited, but is provided closer to the upper part in the present embodiment. In addition, it is preferable that the vertical width of the engagement groove 841 has a certain length so that the engagement range with the main body side guide portion 32 is widened. In this embodiment, the engagement groove 841 is the bread container 80. It is the structure extended to upper end vicinity. In this embodiment, the bottom surface of the engaging groove 841 has a step structure (the groove depth is deep on the upper side and the groove depth is shallow on the lower side). A configuration that does not occur (for example, a configuration in which the entire depth is the same as that of the lower portion of the present embodiment) may be used.

  FIG. 8 is a schematic diagram for explaining the relationship between the main body side guide part and the bread container side guide part when the bread container is accommodated in the baking chamber. FIG. 8A shows a state before the main body side guide portion 32 and the bread container side guide portion 84 start engagement. FIG. 8B shows a state in which the main body side guide portion 32 and the bread container side guide portion 84 are engaged, and the state before the bread container 80 reaches the set position of the baking chamber 30. FIG. 8C shows a state where the main body side guide portion 32 and the bread container side guide portion 84 are engaged, and the bread container 80 has reached the set position of the baking chamber 30. The broken line arrows in FIG. 8 indicate the moving direction of the bread container 80 when the bread container 80 is accommodated in the baking chamber 30 (the direction in which the bread container 80 is lowered).

  As shown in FIG. 8, when the bread container 80 oriented in a predetermined direction is lowered in the direction of the broken arrow (assuming a state from FIG. 8A to FIG. 8B), the bread container side guide portion 84. And the main body side guide portion 32 are started to be engaged. Specifically, the projecting piece 322 of the main body side guide part 32 is sandwiched between the engagement grooves 841 of the bread container side guide part 84. As a result, the bread container 80 then moves while being guided by the main body side guide portion 32. By this guidance, the engagement between the engagement groove 14 a provided in the bread container support portion 14 and the engagement protrusion 83 a provided in the base 83 of the bread container 80 is reliably obtained.

  In addition, the main body side guide part 32 is provided so that the upper end side is located in the baking chamber 30 upper end part vicinity. For this reason, when the bread container 80 is accommodated in the baking chamber 30, before the base 83 of the bread container 80 reaches the bread container support part 14, the main body side guide part 32 guides the bread container side guide part 84. Is started. Further, when the bread container side guide portion 84 is in the vicinity of the upper end portion of the baking chamber 30, the main body side guide portion 32 is engaged with the bread container side guide portion 84, so that the user changes the orientation of the bread container 80. It can be easily adjusted while visually confirming the direction in which the engagement between the container side guide portion 84 and the main body side guide portion 32 is obtained.

  When the engagement between the bread container side guide part 84 and the main body side guide part 32 is started, the protruding piece part 322 of the main body side guide part 32 starts to press the bread container 80. However, since the protruding piece portion 322 has a configuration in which the upper side from the middle of the protruding piece portion 322 does not protrude so much with respect to the fixed portion 321, the force by which the protruding piece portion 322 presses the bread container 80 at the engagement start stage. Is small, and it is easy to move the bread container 80 downward.

  When the bread container 80 is further lowered in a state of being guided by the main body side guide portion 32 (assuming a state from FIG. 8B to FIG. 8C), the protrusion piece portion 322 of the main body side guide portion 32 A portion (lower side) that protrudes greatly with respect to the fixing portion 321 is engaged with the engagement groove 841 of the bread container side guide portion 84. In a state where the bread container 80 has reached the set position of the baking chamber 30, the lower side of the projecting piece 322 is pushed by the bread container side guide 84 and greatly deformed. As a result, the bread container 80 is strongly pressed by the projecting piece 322, and the bread container 80 is fixed so as not to move (raise) in the baking chamber 30.

  In the present embodiment, since the auxiliary protrusion 325 provided on the fixing portion 321 is pushed and deformed by the protrusion 322 in a state where the bread container 80 has reached the set position of the baking chamber 30, this auxiliary The reaction force of the projecting piece 325 also becomes a force for pressing the bread container 80. For this reason, the bread container 80 can be fixed more reliably.

  By the way, a blade unit 90 is detachably attached to a portion of the blade rotating shaft 82 that protrudes into the bread container 80 from above. The configuration of the blade unit 90 will be described with reference to FIGS. 9 to 13.

  FIG. 9 is a schematic perspective view showing the configuration of the blade unit provided in the automatic bread maker of the present embodiment. FIG. 10 is a schematic exploded perspective view showing a configuration of a blade unit provided in the automatic bread maker of the present embodiment. FIG. 11 is a diagram showing a configuration of a blade unit provided in the automatic bread maker of the present embodiment, FIG. 11 (a) is a schematic side view, and FIG. 11 (b) is at the AA position in FIG. 11 (a). It is sectional drawing. FIG. 12 is a schematic plan view of the blade unit included in the automatic bread maker according to the present embodiment when viewed from below. FIG. 12A is a diagram when the kneading blade is in a folded position, and FIG. FIG. 4 is a view when the kneading blade is in an open posture. FIG. 12 shows a state in which a guard to be described later is removed. FIG. 13 is a view for explaining the operation of the blade unit provided in the automatic bread maker of the present embodiment, and is a view when the bread container is viewed from above. FIG. 13A is a view when the kneading blade is in the folded position, and FIG. 13B is a view when the kneading blade is in the open position.

  The blade unit 90 is roughly attached to the unit shaft 91, the pulverizing blade 92 that is attached to the unit shaft 91 so as not to rotate relative to the unit shaft 91, and the relative rotation to the unit shaft 91 so as to cover the pulverizing blade 92 from above. A configuration comprising: a dome-shaped cover 93 that is substantially circular in plan view; a kneading blade 101 that is attached to the dome-shaped cover 93 so as to be relatively rotatable; and a guard 106 that is attached to the dome-shaped cover 93 and covers the grinding blade 92 from below. (For example, refer to FIGS. 9 to 11).

  In the state where the blade unit 90 is attached to the blade rotation shaft 82, the crushing blade 92 is located at a position slightly above the bottom surface of the recess 81 of the bread container 80. Further, almost the entire grinding blade 92 and the dome-shaped cover 93 are accommodated in the recess 81 (see, for example, FIG. 4).

  The unit shaft 91 is a substantially cylindrical member formed of a metal such as a stainless steel plate, for example, and has an opening at one end (lower end), and the inside is hollow. That is, the unit shaft 91 has a configuration in which an insertion hole 91c is formed so that the blade rotation shaft 82 can be inserted from the lower end (see, for example, FIG. 11B).

  Further, a pair of cutout portions 91a are formed on the lower side (opening side) of the side wall of the unit shaft 91 so as to be symmetrically arranged with respect to the rotation center of the unit shaft 91 (see, for example, FIG. 10). FIG. 10 shows only one of the pair of cutout portions 91a). The shape of the notch 91a is substantially rectangular in a side view, and in detail, one end (upper end) is rounded. The notch 91a is provided to engage the pin 821 (see FIG. 11B) that penetrates the blade rotation shaft 82 horizontally. When the pin 821 of the blade rotating shaft 82 and the notch 91a are engaged, the unit shaft 91 is attached to the blade rotating shaft 82 so as not to be relatively rotatable.

  As shown in FIG. 11 (b), the inner side of the unit shaft 91 is engaged with the convex portion 82b provided at the center of the upper end surface (substantially circular) of the blade rotation shaft 82 (shown by a broken line). A recess 91b is formed at the center of the upper surface of the substrate. Accordingly, the blade unit 90 can be easily attached to the blade rotation shaft 82 in a state where the centers of the unit shaft 91 and the blade rotation shaft 82 are aligned. For this reason, when the blade rotating shaft 82 is rotated, occurrence of unnecessary rattling is suppressed. In the present embodiment, the convex portion 82b is provided on the blade rotating shaft 82 side and the concave portion 91b is provided on the unit shaft 91 side, but conversely, the concave portion is provided on the blade rotating shaft 82 side and the unit shaft 91 side is provided. A configuration in which a convex portion is provided may be employed.

  The pulverizing blade 92 for pulverizing grains is formed by processing a stainless steel plate, for example. For example, as illustrated in FIG. 10, the pulverizing blade 92 includes a first cutting portion 921, a second cutting portion 922, and a connecting portion 923 that connects the first cutting portion 921 and the second cutting portion 922. And comprising. An opening 923 a having a substantially rectangular shape (stadium shape) in plan view is formed at the center of the connecting portion 923. The grinding blade 92 is attached to the unit shaft 91 such that the lower side of the unit shaft 91 is fitted into the opening 923a.

  A flat surface is formed on the lower side of the unit shaft 91 by shaving a part of the side surface (near the position where the notch 91a is provided). Thereby, when the unit shaft 91 is viewed from below, the lower side of the unit shaft 91 has substantially the same shape (substantially rectangular shape) as the opening 923a provided in the connecting portion 923. The area when the lower side of the unit shaft 91 is viewed in plan is slightly smaller than the opening 923a. Since such a shape is adopted, the grinding blade 92 is attached to the unit shaft 91 so as not to be relatively rotatable. Since the stopper member 94 for preventing the retaining member 94 is fitted into the unit shaft 91 on the lower side of the pulverizing blade 92, the pulverizing blade 92 does not fall off the unit shaft 91.

  The dome-shaped cover 93 disposed so as to surround and cover the crushing blade 92 is made of, for example, an aluminum alloy die-cast product, and a bearing 95 (in this embodiment, a rolling bearing is used on the inner surface side thereof. ) (See FIG. 11B) is formed. In other words, in order to form the accommodating portion 931, the dome-shaped cover 93 has a configuration in which a substantially cylindrical convex portion 93a is formed at the center when viewed from the outer surface. In addition, the opening is not formed in the convex part 93a, and the bearing 95 accommodated in the accommodating part 931 is in the state in which the side surface and the upper surface are enclosed by the wall surface of the accommodating part 931.

  The inner ring 95a is attached to the unit shaft 91 so as not to rotate relative to the bearing 95 with the retaining rings 96a and 96b arranged on the upper and lower sides (the unit shaft 91 is press-fitted into a through hole inside the inner ring 95a. ing). The bearing 95 is press-fitted into the housing portion 931 so that the outer wall of the outer ring 95b is fixed to the side wall of the housing portion 931. The dome-shaped cover 93 is attached to the unit shaft 91 so as to be rotatable relative to the bearing 95 (the inner ring 95a rotates relative to the outer ring 95b).

  In addition, the housing portion 931 of the dome-shaped cover 93 is made of, for example, a silicon-based material so that foreign matter (for example, liquid used when pulverizing grain grains or paste-like material obtained by pulverization) does not enter the bearing 95 from the outside. Alternatively, a seal material 97 formed of a fluorine-based material and a metal seal cover 98 that holds the seal material 97 are press-fitted from the lower side of the bearing 95. The seal cover 98 is fixed to the dome-shaped cover 93 with a rivet 99 so that the fixing to the dome-shaped cover 93 is ensured. Although fixing with the rivet 99 may not be performed, it is preferable to configure as in the present embodiment in order to obtain reliable fixing. The sealing material 97 and the sealing cover 98 function as sealing means.

  On the outer surface of the dome-shaped cover 93, a kneading blade 101 (for example, aluminum) in a planar shape is formed by a support shaft 100 (see FIG. 10) arranged so as to extend in a vertical direction at a location adjacent to the convex portion 93 a. (Made of die-cast alloy product) is attached. The kneading blade 101 is attached to the support shaft 100 so as not to be relatively rotatable, and moves together with the support shaft 100 attached to the dome-shaped cover 93 so as to be relatively rotatable. In other words, the kneading blade 101 is attached to the dome-shaped cover 93 so as to be relatively rotatable.

  On one surface near the tip of the kneading blade 101 (assuming a portion that draws the largest circle when the kneading blade 101 is rotated about the support shaft 100), a cushioning material 107 as shown in FIGS. It is attached. The buffer material 107 is provided so as to slightly protrude from the tip of the kneading blade 101 (see, for example, FIG. 12B). In the present embodiment, it is provided so as to protrude about 3 mm (d≈3 mm).

  The buffer material 107 is fixed in a state where the buffer material 107 is sandwiched between one surface of the kneading blade 101 and the fixing plate 108 and obtained by caulking the rivet 109 inserted from the other surface side of the kneading blade 101. ing. In the present embodiment, the number of rivets 109 is two, but it goes without saying that the number is not limited.

  The cushioning material 107 is disposed so as not to come into direct contact with the bread container 80 (inner wall thereof) when the kneading blade 101 is in the open posture described in detail later. When the kneading blade 101 and the bread container 80 are in direct contact with each other, damage may occur due to interference between them, and the buffer material 107 is provided to prevent such damage.

  In the automatic bread maker 1 of this embodiment, the surface of the bread container 80 and the kneading blade 101 is coated with fluorine. For this reason, it can be said that the buffer material 107 of the present embodiment is provided so that the fluorine coating is not peeled off by contact between the kneading blade 101 and the pan container 80. From this point, the material constituting the cushioning material 107 is preferably a material softer than the coating material so as not to peel off the fluorine coating. For example, silicone rubber or TPE (Thermoplastic Elastomers) is used. . The buffer material 107 also functions as a soundproofing measure, which will be described later. In the following description, the buffer material 107 may be regarded as a part of the kneading blade 101.

  Further, in the present embodiment, a complementary kneading blade 102 (for example, made of an aluminum alloy die cast product) is fixedly disposed on the outer surface of the dome-shaped cover 93 so as to be aligned with the kneading blade 101. The complementary kneading blade 102 is not necessarily provided, but is preferably provided in order to increase the kneading efficiency in the kneading process of kneading the bread dough.

  Here, the operation of the kneading blade 101 will be described. The kneading blade 101 rotates around the axis of the support shaft 100 together with the support shaft 100, and the folding posture shown in FIGS. 9, 11, 12A and 13A, and FIGS. Two postures are taken, the open posture shown in (b). In the folded position, the protrusion 101a (see FIG. 10) hanging from the lower edge of the kneading blade 101 abuts on the first stopper portion 93b provided on the upper surface (outer surface) of the dome-shaped cover 93. For this reason, the kneading blade 101 cannot further rotate counterclockwise (assuming the case viewed from above) with respect to the dome-shaped cover 93. In this folded position, the tip of the kneading blade 101 protrudes slightly from the dome-shaped cover 93.

  When the kneading blade 101 is rotated clockwise (assumed when viewed from above) with respect to the dome-shaped cover 93 from this posture (the state shown in FIG. 13A), the open posture shown in FIG. The tip of the kneading blade 101 protrudes greatly from the dome-shaped cover 93. The opening angle of the kneading blade 101 in this opening posture is limited by the second stopper portion 93 c (see FIG. 12) provided on the inner surface of the dome-shaped cover 93. When the second engagement body 103b (fixed to the support shaft 100), which will be described in detail later, is unable to rotate by hitting the second stopper portion 93c provided on the inner surface of the dome-shaped cover 93, the kneading blade 101 is at its maximum. The opening angle.

  When the kneading blade 101 is in the folded position, the complementary kneading blade 102 is aligned with the kneading blade 101 as shown in FIGS. 9 and 11, for example. The size becomes larger.

  Incidentally, for example, as shown in FIG. 10, a first engagement body 103 a constituting the cover clutch 103 is attached to the unit shaft 91 between the crushing blade 92 and the seal cover 98. For example, a substantially rectangular (stadium-shaped) opening 103aa is formed in the first engaging body 103a made of zinc die casting, and a substantially rectangular portion in plan view on the lower side of the unit shaft 91 is fitted into the opening 103aa. Thus, the first engagement body 103a is attached to the unit shaft 91 so as not to be relatively rotatable. The first engaging body 103a is attached from the lower side of the unit shaft 91 prior to the crushing blade 92, and the stopper member 94 prevents the unit shaft 91 from dropping off together with the crushing blade 92. In the present embodiment, the washer 104 is disposed between the first engagement body 103a and the seal cover 98 in consideration of prevention of deterioration of the first engagement body 103a. However, the washer 104 is not necessarily provided. It does not have to be provided.

  A second engagement body 103b constituting the cover clutch 103 is attached to the lower side of the support shaft 100 to which the kneading blade 101 is attached. For example, a substantially rectangular (stadium-shaped) opening 103ba is formed in the second engaging body 103b made of zinc die casting, and a substantially rectangular portion in plan view on the lower side of the support shaft 100 is fitted into the opening 103ba. The second engagement body 103b is attached to the support shaft 100 so as not to be relatively rotatable. In the present embodiment, the washer 105 is arranged on the upper side of the second engagement body 103b in consideration of prevention of deterioration of the second engagement body 103b. However, the washer 105 is not necessarily provided.

  The cover clutch 103 composed of the first engagement body 103a and the second engagement body 103b functions as a clutch that switches whether or not to transmit the rotational power of the blade rotation shaft 82 to the dome-shaped cover 93. In the cover clutch 103, the rotation direction of the blade rotation shaft 82 when the kneading motor 50 rotates the drive shaft 11 (this rotation direction is referred to as “forward rotation”. In FIG. 12, the counterclockwise rotation is illustrated, and in FIG. In this case, the rotational power of the blade rotary shaft 82 is transmitted to the dome-shaped cover 93. Conversely, the rotation direction of the blade rotation shaft 82 when the crushing motor 60 rotates the driving shaft 11 (this rotation direction is referred to as “reverse rotation”. In FIG. 12, clockwise rotation, and in FIG. 13 counterclockwise rotation). In this case, the cover clutch 103 does not transmit the rotational power of the blade rotation shaft 82 to the dome-shaped cover 93. Hereinafter, the operation of the cover clutch 103 will be described in more detail.

  When the kneading blade 101 is in the folded position (for example, the state shown in FIGS. 12A and 13A), the engaging portion 103bb of the second engaging body 103b is engaged with the engaging portion 103ab of the first engaging body 103a (this embodiment). The angle is an angle that interferes with the rotation trajectory (there are two in the form but may be one) (see the broken line in FIG. 12A). Therefore, when the blade rotation shaft 82 rotates in the forward direction, the first engagement body 103 a and the second engagement body 103 b are engaged, and the rotational power of the blade rotation shaft 82 is transmitted to the dome-shaped cover 93.

  On the other hand, when the kneading blade 101 is in the open posture (for example, the state shown in FIGS. 12B and 13B), the engaging portion 103bb of the second engaging body 103b is the same as the engaging portion 103ab of the first engaging body 103a. The angle deviates from the rotation trajectory (see the broken line in FIG. 12B). For this reason, even if the blade rotation shaft 82 rotates, the first engagement body 103a and the second engagement body 103b are not engaged. Accordingly, the rotational power of the blade rotation shaft 82 is not transmitted to the dome-shaped cover 93.

  For example, as shown in FIGS. 9 and 10, the dome-shaped cover 93 is formed with a window 93 d that communicates the space inside the cover and the space outside the cover. The window 93d is arranged at a height equal to or higher than the grinding blade 92. In the present embodiment, a total of four windows 93d are arranged at intervals of 90 °, but other numbers and arrangement intervals can be selected.

  Further, a total of four ribs 93e are formed on the inner surface of the dome-shaped cover 93 corresponding to each window 93d (see FIG. 12). Each rib 93e extends obliquely in the radial direction from the vicinity of the center of the dome-shaped cover 93 to the outer peripheral annular wall, and the four ribs 93e form a kind of bowl shape. Moreover, each rib 93e is curving so that the side which faces the bread raw material pressed toward it may become convex.

  A guard 106 is detachably attached to the lower surface of the dome-shaped cover 93. The guard 106 covers the lower surface of the dome-shaped cover 93 and prevents the user's finger from approaching the grinding blade 92. The guard 106 is formed of, for example, an engineering plastic having heat resistance, and can be a molded product such as PPS (polyphenylene sulfide). The guard 106 need not be provided, but is preferably provided for the purpose of ensuring the safety of the user.

  For example, as shown in FIG. 10, at the center of the guard 106, there is a ring-shaped hub 106a through which a stopper member 94 fixed to the unit shaft 91 is passed. Further, at the periphery of the guard 106, there is a ring-shaped rim 106b provided concentrically outside the hub 106a. The hub 106a and the rim 106b are connected by a plurality of spokes 106c. The plurality of spokes 106c are arranged at a predetermined interval, and between the spokes 106c are openings 106d through which grain grains pulverized by the pulverizing blade 92 pass. The opening 106d has a size that prevents a finger from passing through.

  When the spoke 106 c of the guard 106 is attached to the dome-shaped cover 93, the spoke 106 c comes into close proximity with the grinding blade 92. The guard 106 is shaped like an outer blade of a rotary electric razor, and the grinding blade 92 is shaped like an inner blade.

  On the periphery of the rim 106b, a total of four columns 106e (not limited to this configuration) are integrally formed at intervals of 90 °. A horizontal groove 106ea having one end dead end is formed on a side surface of the pillar 106e facing the center side of the guard 106. The guard 106 is attached to the dome-shaped cover 93 by engaging the groove 106ea with the projections 93f formed on the outer periphery of the dome-shaped cover 93 (which are also arranged at a total interval of 45 °). . Although detailed description is omitted, the groove 106ea and the protrusion 93f are provided so as to constitute a bayonet coupling. Each of the plurality of pillars 106e is inclined such that the side surface 106eb that is the front surface in the rotation direction is obliquely upward when the blade rotation shaft 82 rotates in the forward direction.

  As described above, in the automatic bread maker 1 of the present embodiment, since the crushing blade 92 and the kneading blade 101 are incorporated into one unit (blade unit 90), the handling thereof is convenient. The user can easily pull out the blade unit 90 from the blade rotating shaft 82, and can easily clean the blade after the bread making operation. Further, the pulverizing blade 92 provided in the blade unit 90 is detachably attached to the unit shaft 91, and is easily mass-produced and has excellent maintainability such as blade replacement.

  Further, in the automatic bread maker 1 of the present embodiment, since a liquid such as water is put into the bread container 80, the bearing 95 is preferably sealed to prevent the liquid from entering the bearing 95. In this respect, in the automatic bread maker 1, since the bearing 95 is accommodated in the concave accommodating portion 931 provided in the dome-shaped cover 93, the sealing means (the sealing material 97 and the seal cover only on the inner surface side of the dome-shaped cover 93). 98), a structure for sealing the bearing 95 is obtained. For this reason, it is not necessary to provide sealing means above and below the bearing 95, and the seal structure of the bearing 95 can be downsized. For this reason, in the automatic bread maker 1, it is possible to suppress an adverse effect on the shape of the baked bread (for example, the bottom surface of the bread is greatly recessed).

  FIG. 14 is a block diagram showing the configuration of the automatic bread maker of the present embodiment. As shown in FIG. 14, the control operation in the automatic bread maker 1 is performed by the control device 120. The control device 120 is configured by, for example, a microcomputer including a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and an input / output (I / O) circuit unit. . The control device 120 is preferably disposed at a position that is not easily affected by the heat of the baking chamber 30. Further, the control device 120 is provided with a time measuring function, and temporal control in the bread manufacturing process is possible.

  The control device 120 includes the operation unit 20, the temperature sensor 15 that detects the temperature of the baking chamber 30, a kneading motor drive circuit 121, a grinding motor drive circuit 122, a heater drive circuit 123, and a first solenoid. The drive circuit 124 and the second solenoid drive circuit 125 are electrically connected.

  The kneading motor driving circuit 121 is a circuit for controlling the driving of the kneading motor 50 under a command from the control device 120. The grinding motor drive circuit 122 is a circuit for controlling the driving of the grinding motor 60 under a command from the control device 120. The heater drive circuit 123 is a circuit for controlling the operation of the sheathed heater 31 under a command from the control device 120. The first solenoid drive circuit 124 controls the drive of the automatic charging solenoid 16 that is driven when a part of the bread ingredients is automatically charged in the course of the bread manufacturing process under the command from the control device 120. Circuit. The second solenoid drive circuit 125 is a circuit for controlling the drive of the clutch solenoid 73 (see FIG. 3) that switches the state of the clutch 56 (see FIG. 3) under a command from the control device 120.

The control device 120 reads a program relating to a bread manufacturing course (breadmaking course) stored in a ROM or the like based on an input signal from the operation unit 20, and a kneading blade by the kneading motor 50 via the kneading motor driving circuit 121. 101, rotation control of the complementary kneading blade 102, control of rotation of the pulverization blade 92 by the pulverization motor 60 via the pulverization motor drive circuit 122, control of heating operation by the sheathed heater 31 via the heater drive circuit 123, The automatic bread maker 1 controls the operation of the movable hook 42c by the automatic closing solenoid 16 via the solenoid driving circuit 124 and the switching control of the clutch 56 by the clutch solenoid 73 via the second solenoid driving circuit 125. Execute bread manufacturing process.
(Operation of automatic bread machine)
Next, the operation in the case of producing bread with the automatic bread maker 1 configured as described above will be described. Here, the operation of the automatic bread maker 1 will be described by taking as an example a case where bread is produced by using the rice grain as a starting material by the automatic bread maker 1.

  When rice grains are used as a starting material, a bread-making course for rice grains is executed. FIG. 15 is a schematic diagram showing the flow of the bread making course for rice grains executed by the automatic bread maker. As shown in FIG. 15, in the bread making course for rice grains, the dipping process, the pulverizing process, the resting process, the kneading (kneading) process, the fermentation process, and the baking process are sequentially performed in this order. The

  In starting the rice grain breadmaking course, the user attaches the blade unit 90 to the blade rotation shaft 82 by covering the blade rotation shaft 82 of the bread container 80 with the unit shaft 91. As described above, since the blade unit 90 includes the guard 106, the user's finger does not touch the crushing blade 92 during this work, and the user can work safely. After the operation of attaching the blade unit 90, the user weighs rice grains, water, and seasonings (for example, salt, sugar, shortening, etc.) in predetermined amounts and puts them in the bread container 80.

  In addition, the user weighs the bread ingredients that are automatically added during the bread manufacturing process and puts them in the container body 42 a of the bread ingredient storage container 42. When the bread material to be stored is stored in the container body 42a, the container lid 42b is supported by the movable hook 42c, and the opening of the container body 42a is closed by the container lid 42b.

  In addition, as a bread raw material accommodated in the bread raw material storage container 42, gluten, dry yeast, etc. are mentioned, for example. Instead of gluten, for example, at least one of flour, thickener (eg, guar gum), and upper fresh powder may be stored in the bread ingredient storage container 42. In addition, for example, only dry yeast may be stored in the bread raw material storage container 42 without using gluten, wheat flour, thickener, super fresh powder or the like. Further, in some cases, seasonings such as salt, sugar, and shortening are stored in the bread ingredient storage container 42 together with, for example, gluten and dry yeast so as to be automatically introduced during the bread manufacturing process. May be. In this case, the bread raw material previously put into the bread container 80 is rice grains and water (in place of mere water, for example, a liquid having a taste component such as soup stock, a liquid containing fruit juice or alcohol, etc.) Become.

  Thereafter, the user puts the bread container 80 into the baking chamber 30 and further attaches the bread ingredient storage container 42 to a predetermined position of the lid 40. Then, the user closes the lid 40, selects the rice grain breadmaking course using the operation unit 20, and presses the start key. Thereby, the control apparatus 120 starts control operation | movement of the bread-making course for rice grains which manufactures bread using a rice grain as a starting material.

  The bread container 80 can be attached smoothly due to the presence of the main body side guide portion 32 and the bread container side guide portion 84. In particular, the main body side guide portion 32 extends to the vicinity of the upper end portion of the baking chamber 30. For this reason, the main body side guide part 32 starts to engage with the bread container side guide part 84 when the bread container side guide part 84 is in the vicinity of the upper end part of the baking chamber 30. The pedestal 83 does not reach the bread container support part 14. Therefore, the user can easily adjust the orientation of the bread container 80 and attach the bread container 80 to the baking chamber 30. Moreover, since the main body side guide part 32 has elasticity, the bread container 80 can be firmly fixed. Further, in such a fixing method, the fixing function does not vary depending on the rotation direction of the blade rotation shaft 82.

  When the rice grain breadmaking course is started, the dipping process is started by a command from the control device 120. In the dipping process, the bread raw material previously put in the bread container 80 is set in a stationary state, and the stationary state is maintained for a predetermined time (30 minutes in the present embodiment). This dipping process is a process aimed at making the rice grains easy to be pulverized to the core in the subsequent pulverization process by adding water to the rice grains.

  The water absorption speed of rice grains varies depending on the temperature of the water. If the water temperature is high, the water absorption speed increases, and if the water temperature is low, the water absorption speed decreases. For this reason, you may make it fluctuate the time of an immersion process with the environmental temperature etc. in which the automatic bread maker 1 is used, for example. Thereby, it becomes possible to suppress the dispersion | variation in the water absorption degree of a rice grain. Further, in order to shorten the immersion time, the sheathed heater 31 may be energized to increase the temperature of the firing chamber 30.

  Further, the grinding blade 92 may be rotated at the initial stage of the dipping process, and further, the grinding blade 92 may be intermittently rotated thereafter. If it does in this way, the surface of a rice grain can be damaged, and the liquid absorption efficiency of a rice grain will be improved.

  When the predetermined time elapses, the dipping process is ended by a command from the control device 120, and a crushing process for crushing the rice grains is started. In this pulverization step, the pulverization blade 92 is rotated at a high speed (for example, 7000 to 8000 rpm) in a mixture containing rice grains and water. In this crushing step, the control device 120 controls the crushing motor 60 to rotate the blade rotation shaft 82 in the reverse direction (clockwise rotation in FIG. 12 and counterclockwise rotation in FIG. 13). Since the cutting blade of the crushing blade 92 is moved forward in the rotation direction by the reverse rotation of the blade rotation shaft 82, a crushing function using the crushing blade 92 is obtained.

  When rotating the grinding blade 92 using the grinding motor 60, the control device 120 drives the clutch solenoid 73 so that the clutch 56 shuts off the power (the state shown in FIG. 3A). ). This is because, as described above, there is a possibility that the motor is damaged unless it is controlled in this way.

  When the blade rotation shaft 82 is rotated in the reverse direction to rotate the grinding blade 92, the dome-shaped cover 93 also starts to rotate following the rotation of the blade rotation shaft 82. The rotation of the cover 93 is immediately blocked (stopped). It is preferable that the pulverizing blade 92 is rotated at a low speed in the initial stage of the pulverization process and then rotated at a high speed.

  The rotation direction of the dome-shaped cover 93 accompanying the rotation of the blade rotation shaft 82 for rotating the grinding blade 92 is the counterclockwise direction in FIG. 13, and the kneading blade 101 has been folded until then (see FIG. 13A). In the case of the posture shown in FIG. 13, the posture is changed to the open posture (posture shown in FIG. 13B) by the resistance received from the mixture containing rice grains and water.

  When the kneading blade 101 is in the open posture, the engagement portion 103bb of the second engagement body 103b deviates from the rotation track of the engagement portion 103ab of the first engagement body 103a (see the broken line in FIG. 12). For this purpose, the cover clutch 103 disconnects the blade rotation shaft 82 from the dome-shaped cover 93. In addition, as shown in FIG. 13B, a part of the kneading blade 101 in the open position (more precisely, the cushioning material 107 provided on the front end side) is formed on the inner wall of the bread container 80 (more specifically, The rotation of the dome-shaped cover 93 is prevented (stopped) in order to come into contact with the bowl-shaped protrusion 80b provided on the inner wall of the bread container 80 in order to improve the grinding efficiency.

  In the crushing process, vibration is generated while the crushing blade 92 is rotating. However, since the cushioning material 107 is in contact with the bread container 80, the collision sound generated by this vibration is reduced. It has become.

  The pulverization of the rice grains in the pulverization step is performed in a state where water is soaked in the rice grains by the previously performed immersion step, and thus the rice grains can be easily pulverized to the core. In the present embodiment, the rotation of the pulverizing blade 92 in the pulverization step is intermittent. This intermittent rotation is performed, for example, in a cycle of rotating for 30 seconds and stopping for 5 minutes, and this cycle is repeated 10 times. In the last cycle, the stop for 5 minutes is not performed. The rotation of the crushing blade 92 may be continuous rotation, but for the purpose of, for example, preventing the temperature of the raw material in the bread container 80 from becoming too high, it is preferable to perform intermittent rotation.

  In the pulverization step, the pulverization of the rice grains is performed in the dome-shaped cover 93 whose rotation is stopped, so that the possibility that the rice grains scatter outside the bread container 80 is low. Further, the rice grains entering the dome-shaped cover 93 from the opening 106d of the guard 106 in the rotation stopped state are sheared between the stationary spoke 106c and the rotating pulverizing blade 92, so that the pulverization can be performed efficiently. Further, the rib 93e provided on the dome-shaped cover 93 suppresses the flow of the mixture containing rice grains and water (flow in the same direction as the rotation of the grinding blade 92), so that the grinding can be performed efficiently.

  Further, the mixture containing the pulverized rice grains and water is guided in the direction of the window 93d by the rib 93e of the dome-shaped cover 93 and is discharged out of the dome-shaped cover 93 from the window 93d. Since the rib 93e of the dome-shaped cover 93 is curved so that the side facing the mixture pressing toward it is convex, the mixture hardly stays on the surface of the rib 93e and flows smoothly toward the window 93d. . Further, instead of the mixture being discharged from the inside of the dome-shaped cover 93, the mixture existing in the space above the concave portion 81 enters the concave portion 81 and passes through the opening portion 106d of the guard 106 from the concave portion 81. Enter the cover 93. Since the pulverization by the pulverization blade 92 is performed while being circulated as described above, the pulverization can be performed efficiently.

  In the automatic bread maker 1, the crushing process is completed in a predetermined time (in this embodiment, 50 minutes). However, the grain size of the pulverized powder may vary depending on the hardness of the rice grains and the environmental conditions. For this reason, the end of the pulverization process may be determined based on the magnitude of the load of the pulverization motor 60 (for example, it can be determined by the control current of the motor).

  When the pulverization process is completed, a pause process is executed according to a command from the control device 120. This pause process is provided as a cooling period during which the temperature of the contents in the bread container 80 raised by the crushing process is lowered. The reason for lowering the temperature is that the next kneading step is carried out at a temperature at which the yeast is active (for example, around 30 ° C.). In the present embodiment, the pause process is a predetermined time (30 minutes). However, in some cases, the pause process may be performed until the temperature of the bread container 80 reaches a predetermined temperature.

  When the pause process ends, the kneading process is started by a command from the control device 120. At the start of the kneading process, the control device 120 drives the clutch solenoid 73 so that the clutch 56 transmits power (state shown in FIG. 3B). The control device 120 controls the kneading motor 50 to rotate the blade rotation shaft 82 in the forward direction (counterclockwise rotation in FIG. 12 and clockwise rotation in FIG. 13).

  When the blade rotation shaft 82 is rotated in the forward direction, the grinding blade 92 is also rotated in the forward direction. In this case, the pulverizing blade 92 rotates with the cutting blade behind in the rotation direction, and does not exhibit the pulverizing function. Due to the rotation of the grinding blade 92, the bread ingredients around the grinding blade 92 flow in the forward direction. Accordingly, when the dome-shaped cover 93 moves in the forward direction (clockwise in FIG. 13), the kneading blade 101 receives resistance from the non-flowing bread material and is folded from the open position (see FIG. 13B). The angle is changed to (see FIG. 13A). As a result, the engaging portion 103bb of the second engaging body 103b has an angle that interferes with the rotation trajectory (see the broken line in FIG. 12) of the engaging portion 103ab of the first engaging body 103a. Then, the cover clutch 103 connects the blade rotation shaft 82 and the dome-shaped cover 93, and the dome-shaped cover 93 enters a state of being driven in earnest by the blade rotation shaft 82. The dome-shaped cover 93 and the kneading blade 101 in the folded position rotate together with the blade rotation shaft 82 in the forward direction.

  In order to reliably connect the cover clutch 103 described above, it is preferable that the rotation of the blade rotation shaft 82 at the initial stage of the kneading process is intermittent rotation or low speed rotation. Further, as described above, when the kneading blade 101 is in the folded position, the complementary kneading blade 102 is arranged on the extension of the kneading blade 101, so that the kneading blade 101 is enlarged and the bread raw material is pressed strongly. It is. For this reason, the dough can be kneaded firmly.

  The rotation of the kneading blade 101 (this term is used as an expression including the complementary kneading blade 102 in the folded position, the same applies hereinafter) is very slow in the initial stage of the kneading process, and the speed is increased stepwise. Control is performed by the control device 120. In the initial stage of the kneading process in which the kneading blade 101 rotates very slowly, the control device 120 drives the automatic charging solenoid 16 so that the movable hook 42c of the bread ingredient storage container 42 supports the container lid 42b. Let go. Thereby, the opening of the container main body 42a is opened, and for example, bread ingredients such as gluten and dry yeast are automatically charged into the bread container 80.

  As described above, the bread raw material storage container 42 is provided with a coating layer inside the container body 42a and the container lid 42b to improve slipping, and is devised so that there is no uneven portion inside. Yes. Furthermore, the situation where the bread raw material is caught by the packing 42d is also suppressed by the device for arranging the packing 42d. For this reason, the automatic charging is completed with almost no bread ingredients remaining in the bread ingredient storage container 42.

  In this embodiment, the bread ingredients stored in the bread ingredient storage container 42 are charged while the kneading blade 101 is rotating. However, the present invention is not limited to this, and the kneading blade 101 stops. You may throw it in However, as in this embodiment, it is preferable to add the bread ingredients while the kneading blade 101 is rotated because the bread ingredients can be uniformly dispersed.

  After the bread ingredients stored in the bread ingredient storage container 42 are put into the bread container 80, the bread ingredients are kneaded into a dough connected to one having a predetermined elasticity by the rotation of the kneading blade 101. Go. When the kneading blade 101 swings the dough and knocks it against the inner wall of the bread container 80, an element of “kneading” is added to the kneading. As the kneading blade 101 rotates, the dome-shaped cover 93 also rotates. When the dome-shaped cover 93 rotates, the rib 93e formed on the dome-shaped cover 93 also rotates, so that the bread material in the dome-shaped cover 93 is quickly discharged from the window 93d and the kneading blade 101 kneads the bread. Assimilate into a lump of material.

  In the kneading process, the guard 106 is also rotated in the forward direction together with the dome-shaped cover 93. The spoke 106c of the guard 106 has a shape in which the center side of the guard 106 precedes and the outer peripheral side of the guard 106 follows when rotating in the forward direction. For this purpose, the guard 106 rotates in the forward direction to push the bread ingredients (bread dough) inside and outside the dome-shaped cover 93 outward with the spokes 106c. Thereby, the ratio of the raw material used as a waste after baking bread can be reduced.

  Further, the pillar 106e of the guard 106 has a configuration in which a side surface 106eb which is a front surface in the rotational direction when the guard 106 rotates in the forward direction is inclined upward. For this reason, at the time of kneading, the bread material (bread dough) around the dome-shaped cover 93 is splashed upward on the side surface 106eb of the column 106e. Since the boiled bread material is assimilated into the lump (dough) of the upper bread material, the proportion of the raw material that becomes waste after baking the bread can be reduced.

  In the automatic bread maker 1, the time of the kneading process is configured to employ a predetermined time (10 minutes in the present embodiment) obtained experimentally as the time for obtaining dough having a desired elasticity. However, if the time of the kneading process is constant, the degree of bread dough may vary depending on the environmental temperature or the like. For this reason, for example, a configuration in which the end point of the kneading process is determined based on the magnitude of the load of the kneading motor 50 (for example, it can be determined by the control current of the motor) may be used.

  In addition, what is necessary is just to put it in the middle of this kneading process, when baking bread containing ingredients (for example, raisins, nuts, cheese, etc.).

  When the kneading process is finished, the fermentation process is started by a command from the control device 120. In this fermentation process, the control device 120 controls the sheathed heater 31 to maintain the temperature of the baking chamber 30 at a temperature at which fermentation proceeds (for example, 38 ° C.). Then, it is left for a predetermined time (in this embodiment, 60 minutes) in an environment in which fermentation proceeds.

  In some cases, during the fermentation process, the kneading blade 101 may be rotated to perform degassing or dough rounding.

  When the fermentation process ends, the firing process is started by a command from the control device 120. The control device 120 controls the sheathed heater 31 to increase the temperature of the baking chamber 30 to a temperature suitable for baking (for example, 125 ° C.). Then, the control device 120 performs control so that the bread is baked in a baking environment for a predetermined time (in this embodiment, 50 minutes). The end of the firing process is notified to the user by, for example, a display on the liquid crystal display panel of the operation unit 20 or a notification sound. When the user detects the completion of bread making, the user opens the lid 40 and takes out the bread container 80 to complete the bread production.

The bread in the bread container 80 can be taken out, for example, by turning the opening of the bread container 80 obliquely downward. Simultaneously with the removal of the bread, the blade unit 90 attached to the blade rotation shaft 82 is also removed from the bread container 80. Due to the presence of the guard 106, the user does not touch the crushing blade 92 during the bread removal operation, and the user can safely perform the bread removal operation. At the bottom of the bread, burn marks of the kneading blade 101 of the blade unit 90 and the complementary kneading blade 102 (projecting upward from the recess 81 of the bread container 80) remain. However, since the dome-shaped cover 93 and the guard 106 are accommodated in the recess 81, they are prevented from leaving a large burn mark on the bottom of the bread.
(Other)
The embodiment of the automatic bread maker described above is an example of the present invention, and the configuration of the automatic bread maker to which the present invention is applied is not limited to the embodiment described above.

  For example, in the embodiment described above, the projecting piece portion 322 of the main body side guide portion 32 has the bent portions 322a to 322c. However, the present invention is not limited to this configuration. That is, a configuration in which the bent portion is not provided in the protruding piece portion 322 may be employed. Further, in the case where the bent portion is provided in the protruding piece portion 322, the number may be changed from the case of the present embodiment (for example, only the second bent portion 322b is used).

  In the embodiment described above, the main body side guide portion 32 is a separate member from the side wall 30b of the baking chamber 30, but may be provided integrally with the side wall 30b of the baking chamber 30. Also, the bread container guide portion 84 may be provided integrally with the bread container 80.

  In the embodiment described above, the elastic guide portion is disposed on the main body side and the non-elastic guide portion is disposed on the bread container side. However, the present invention is not limited to this configuration. That is, for example, a configuration in which a guide portion having no elasticity on the main body side and a guide portion having elasticity on the bread container side are arranged (a configuration opposite to the present embodiment) may be employed. Furthermore, depending on the case, the structure by which the guide part which does not have elasticity on either the main body side and the bread container side may be employ | adopted.

  In the embodiment described above, the handle 85 (an example of the handle member of the present invention) provided on the bread container 80 so as to be able to stand upside down is part of the handle 85 in the sideways state. It is supported by contacting the part 80a. In the case of such a configuration, the main body portion (specifically, the flange portion 80a) of the bread container 80 is easily damaged by contact with the handle 85.

  Considering this point, as shown in FIG. 16, in the state where the handle 85 is laid down, a part of the handle 85 has a stopper 86 (for example, a rivet or screw) for fixing the bread container side guide portion 84. It is preferable to provide the bread container 80 so that it may contact | abut. Specifically, a part of the handle 85 abuts on a portion protruding from the collar portion 80 a of the stopper 86. If comprised in this way, it can suppress that the main-body part of the bread container 80 is damaged. FIG. 16 is a view showing a modified example of the bread container provided in the automatic bread maker of the present embodiment, FIG. 16 (a) is a schematic perspective view when viewed obliquely from above, and FIG. 16 (b) is the bread container side. It is a schematic side view at the time of arrange | positioning so that the surface in which a guide part is provided may turn into a front.

  In the bread container 80 shown in FIG. 16, the handle 85 and the heel part are not affected when the handle 85 is laid down in any direction (can be laid down in the left-right direction in FIG. 16B) from the standing state. The handle 85 is formed so that a sufficient gap S is formed between the handle 80a and 80a. The gap S allows the user to easily grasp the handle 85 with a heat-resistant tool such as mittens attached when taking out the bread container 80 from the baking chamber 30 after the manufacture of the bread.

  Specifically, the handle 85 is configured to have a convex portion 85a in the vicinity of the support portion 87 (supporting the handle 85 so as to be rotatable) and a portion along the flange portion 80a when folded sideways. The bending that forms the convex portion 85a is opposite to each other on one end side and the other end side of the handle 85. The bending direction is a direction in which a gap is generated between the handle 85 and the flange portion 80a even when the handle 85 is tilted in any direction from the standing state. When the handle 85 is overturned, the vicinity of the convex portion 85 a of the handle 85 abuts against the stopper 86, and the portion of the handle 85 that has fallen from the standing state does not hit the bread container 80.

  In the above-described embodiment, the pulverizing blade 92 and the kneading blade 101 are included in the blade unit 90 and are integrally attached to (removed from) the blade rotation shaft 82. However, the configuration is not limited to this, and the pulverizing blade 92 and the kneading blade 101 may be separately mounted on the blade rotation shaft 82.

  Moreover, in embodiment shown above, the structure and operation | movement of an automatic bread maker were demonstrated for the case where the grain of rice was used as a starting raw material.
