  Next, an outline of the procedure for attaching the bakery means 30 will be described with reference to FIGS.

  FIG. 2 is a perspective view of the main body 1 and shows a state in which the table plate 11 indicated by a broken line is removed and the stirring drive shaft 24 on the bottom surface of the heating chamber 2 is exposed so as to be visible. When installing the bakery means 30, first, the mounting guide 36 is set on the bottom surface of the heating chamber 2 along the side wall inside the heating chamber 2. After that, as shown in FIG. 3, the bakery means 30 is inserted from the front opening 42 and guided by the mounting guide 36, and the bakery means 30 is mounted on the stirring drive shaft 24 on the bottom surface of the heating chamber 2 as shown in FIG.

It can be fixed to the bottom of the heating chamber 2. Details of the configuration and operation will be described later.

<Installation guide>
The mounting guide 36 will be described in detail with reference to FIGS. As shown in FIG. 2, the mounting guide 36 includes a drive shaft hole 37, a guide bottom surface 38, and guide side walls 39. When the mounting guide 36 is set on the bottom surface of the heating chamber 2, the stirring drive shaft 24 passes through the drive shaft hole 37. When mounting the bakery means 30, first, the bakery means 30 is placed on the guide bottom surface 38 of the mounting guide 36 and moved to the back side of the heating chamber 2 while guiding the left and right sides with the guide side wall 39. When the drive connecting portion 31 of the bakery means 30 is moved to the position of the stirring drive shaft 24, the drive connecting portion 31 can be attached to the stirring drive shaft 24, and the stirring blade 27 in the bakery means 30 is powered by the stirring drive shaft 24. Can be communicated.

  In the present embodiment, the width of the left and right guide side walls 39 is wide on the near side and narrow on the far side. By guiding the left and right positions when moving the bakery means 30 to the back side, the positions of the stirring blades 27 and the stirring drive shaft 24 can be matched, and the bakery means 30 can be easily set at a normal position. it can.

  When the mounting guide 36 is set, the weight sensor 10 on the right side of the opening is covered with the mounting guide 36. Therefore, when the bakery means 30 is attached, the bakery means 30 and the weight sensor 10 do not collide with each other. Damage can be avoided. Further, when the bakery means 30 is set, the bakery means 30 moves on the mounting guide 36, so that the bakery means 30 and the bottom surface of the heating chamber 2 do not come into contact with each other, and scratches and wear on the bottom surface of the heating chamber 2 are prevented. it can.

<Removal of bakery means>
When removing the bakery means 30, after opening the door 3, the lock lever 41 is rotated in the release direction (for example, in front of the heating chamber 2) to release the lock, and then the bakery means 30 is lifted up. The bakery means 30 can be taken out from the front opening 42 by moving forward. Thereafter, the ingredient container 29 is lifted and removed from the bread baking container 28, and then the baked bread is taken out from the bread baking container 28.

  In the present embodiment, since the ingredient container 29 is placed on the upper surface of the bread baking container 28, the ingredient container 29 can be easily removed simply by lifting the ingredient container 29. For this reason, the material container 29 can be easily removed even in a state of wearing heat-resistant gloves, and the bread immediately after baking can be easily taken out.

<Ingredient input drive means>
As shown in FIG. 4, the ingredient container 29 placed above the bread baking container 28 includes first ingredient throwing means 43 and second ingredient throwing means 44. The first ingredient input means 43 holds powdery or granulated dry yeast 133, which is yeast that ferments the bread dough 57, in the bread baking container 28, and inputs these into the bread baking container 28 by an external operation. The second ingredient throwing means 44 holds ingredients 135 such as raisins and nuts in the bread baking container 28 and throws them into the bread baking container 28 by an external operation. Note that the bottoms of these material input means are opened by an operation from the material input drive means 47 described later, and the dry yeast 133 and the material 135 can be input into the bread baking container 28.

  Here, since the inside of the heating chamber 2 is heated to about 300 ° C., it is not preferable to install the ingredient charging drive means 47 inside the heating chamber 2. Therefore, in the present embodiment, the first material charging motor 91 and the second material charging motor 97 that function as actuators of the material charging drive means 47 are disposed in the machine chamber 5 that is cooler than the heating chamber 2, The driving force generated here is transmitted to a drive lever 45 provided at a substantially ceiling height of the heating chamber 2 via a push rod 73 provided outside the heating chamber 2. Further, a through hole 74 through which the drive lever 45 passes is provided on the side wall surface of the heating chamber 2 facing the drive lever 45, and the drive lever 45 provided outside the heating chamber 2 passes through the through hole 74 and the heating chamber 2. By operating the first ingredient throwing means 43 and the second ingredient throwing means 44 provided on the inside, the dry yeast 133 and the ingredient 135 can be thrown into the bread baking container 28. In the present embodiment, a configuration in which a motor is used as the actuator of the material loading drive means 47 will be described, but a solenoid or the like may be used instead of the motor.

<Bakery means>
The configuration of the bakery means 30 will be described in more detail using the exploded perspective view of FIG.

  The material container 29 is provided with a plurality of action holes 46 that engage with the drive lever 45 of the material loading drive means 47. It is desirable that the action hole 46 be provided in the vicinity of the material charging drive means 47, and it is preferable that the action hole 46 be provided in a position close to the wall surface of the heating chamber 2 and facing each other.

  Further, the first material input means 43 of the material container 29 is provided on the side of the action hole 46 of the material container 29, and the second material input means 44 is provided on the side opposite to the action hole 46.

  When the ingredient container 29 is not set to the bread baking container 28 in the correct orientation and the ingredient input drive means 47 and the action hole 46 do not face each other, the drive lever 45 of the ingredient input drive means 47 causes the ingredient container 29 to There is a problem that the action hole 46 cannot be operated and the material 135 or the like cannot be input. Therefore, a first protrusion 48 and a second protrusion 49 are provided on the left and right upper ends of the bread baking container 28, and a first recess 50 and a second recess 51 are provided on the left and right lower ends of the ingredient container 29. The first protrusion 48 and the second protrusion 49 have different widths, the first recess 50 is made to correspond to the shape of the first protrusion 48, and the second recess 51 is changed to the shape of the second protrusion 49. This prevents the ingredient container 29 from being placed in an incorrect orientation on the bread baking container 28.

  Further, an air passage 52 through which hot air can flow is provided in the front-rear direction of the lower end of the material container 29 so that hot air can be introduced into the bread baking container 28. In the present embodiment, the second material input means 44 is provided in the direction along the air passage 52 (long in the front-rear direction), and the reason will be described later.

  Here, when the height dimension of the bread baking container 28 including the drive connecting portion 31 is H1, the height dimension of the ingredient container 29 is H2, and the height dimension of the front opening 42 is H3, in this embodiment, H3 The height dimensions of the bread baking container 28, the ingredient container 29, and the front opening 42 were set so as to satisfy> H1 + H2. Thereby, the bakery means 30 can be inserted into the heating chamber 2 from the front opening 42 in the state of the bakery means 30 in which the ingredient container 29 is placed on the bread baking container 28. It should be noted that it is more preferable to set each height dimension so as to satisfy H3> H1 + H2 + 25 mm because the bakery means can be attached and detached with a margin.

<Positional relationship between rear end of ingredient container and rear end of bread baking container>
Next, a suitable positional relationship between the ingredient container 29 and the bread baking container 28 will be described with reference to FIGS.

  FIG. 5 is a cross-sectional view of the main body 1 at the time of bread baking. As shown here, the hot air heated by the hot air heater 21 blows out from the hot air outlet 23 provided on the back surface of the heating chamber 2, While baking 28 from the side, it is blown to the upper surface of the bread dough 57 in the bread baking container 28 through the ventilation path 52, and baking of bread advances.

  FIG. 33 is a longitudinal sectional view showing the positional relationship between the rear end portion 54 of the ingredient container 29 and the rear end portion 55 of the bread baking container 28. As described with reference to FIG. 5, the surface of the bread dough 57 is heated by the hot air 53 flowing into the bread baking container 28 through the ventilation path 52 of the bakery means 30, and baking of the bread is promoted. However, if the bread dough surface 56 becomes partly too hot, the baking will not be uniform, and the baking will not be partly colored, or the baking will be partially completed too early, and the bread will not bulge. There is a problem that it becomes uniform.

  For example, as shown in FIG. 33 (a), when the rear end portion 54 of the material container 29 is in front of the rear end portion 55 of the bread baking container 28, the rear side air passage 52 faces upward. The hot air 53 supplied from the upper hot air outlet 23 easily flows into the ventilation path 52, and in particular, at the bread dough surface 56 on the upstream side of the hot air 53, the hot air 53 directly hits the surface of the bread dough 57, so the temperature is local. In some cases, the swell is not enough to cause the firing to be completed early, and the surface baked color is too strong as compared with other portions.

  Therefore, in this embodiment, as shown in FIG. 33 (b), the front and rear positions of the rear end portion 54 of the ingredient container 29 are aligned with or rearward of the rear end portion 55 of the bread baking container 28. The air passage 52 on the side is prevented from facing upward, and the inflow of the hot air 53 into the bakery means 30 is appropriately inhibited. With this configuration, it is possible to prevent a local temperature rise on the bread dough surface 56 in particular, and to obtain a baked bread that is more uniformly baked and swelled.

<Lock mechanism of bakery means 30>
As a method of locking the bakery means 30 to the bottom surface of the heating chamber 2, a configuration in which the entire bakery means 30 is locked around the vertical axis is also conceivable. However, in this case, since the ingredient container 29 placed on the bread baking container 28 also rotates around the vertical axis, the orientation of the ingredient container 29 at the time of completion of locking is not uniformly determined, and the action of the ingredient container 29 is not achieved. The relative position of the hole 46 and the material loading drive means 47 may be shifted, and the operating hole 46 may not be operated by the drive lever 45 of the material loading drive means 47.

  Therefore, in this embodiment, the lock lever 41 is provided in the drive connection portion 31 of the bread baking container 28 so that the bakery means 30 can be locked without rotating the ingredient container 29. Below, the lock lever 41 provided in the drive connection part 31 of the bread baking container 28 is demonstrated using FIG. 8 and FIG. FIG. 8 is a perspective view of the bread baking container 28 of FIG. 7 as viewed from the C direction. FIG. 9 is a bottom view of the bread baking container 28 of FIG. 8 as viewed from the D direction, and shows the operation of the lock lever 41.

  As shown in FIG. 8, a cylindrical drive connecting portion 31 protruding downward is provided on the bottom surface of the bread baking container 28, and the stirring drive shaft 24 when set on the bottom surface of the heating chamber 2 is provided at the center thereof. And a coupling 59 that transmits a driving force to the stirring blade 27 is provided. The coupling 59 may be an involute spline, or may be configured to transmit rotational torque via a pin that passes through the stirring drive shaft 24 at a right angle.

  A plurality of substantially trapezoidal fixing claws 58 protrude from the lower end of the drive connecting portion 31, and when the bakery means 30 is set in the heating chamber 2, the fixing claws 58 are fitted into holes provided in the bottom surface of the heating chamber 2. Match. The fixing claw 58 also serves as a leg when the bread baking container 28 is placed on a flat surface such as a table.

  A rotating claw 60 having a hook-shaped portion at the tip is provided on the inner peripheral side of the fixed claw 58, and the rotating claw 60 rotates in conjunction with the lock lever 41.

  As shown in FIG. 9A, the entire rotation claw 60 is covered with the fixing claw 58 before the lock lever 41 is rotated. As shown in FIG. 3, when the bakery means 30 is mounted on the bottom surface of the heating chamber 2 in accordance with the mounting guide 36, the fixed claw 58 and the rotation of the fixing claw 58 are rotated in the hole on the bottom surface of the heating chamber 2 provided to fit the fixed claw 58. The claw 60 is removably inserted.

  Thereafter, as shown in FIG. 9B, when the lock lever 41 is rotated, the rotation claw 60 rotates in conjunction with the lock lever 41, and the hook-shaped portion of the rotation claw 60 protrudes from the fixed claw 58. To do. Then, the key-shaped portion of the rotating claw 60 is caught in the hole on the bottom surface of the heating chamber 2, and the bakery means 30 is fixed to the bottom surface of the heating chamber 2.

  By using such a locking mechanism, the bakery means 30 can be fixed while maintaining the orientation of the bakery means 30, so that the working hole 46 of the ingredient container 29 and the ingredient throwing drive means 47 face each other. The relationship can be maintained normally, and the operation hole 46 can be reliably operated by the drive lever 45 of the material loading drive means 47.

  In the present embodiment, the height of the lock lever 41 is about half that of the bread baking container 28. Accordingly, the lock lever 41 having a necessary and sufficient size can be obtained, and the lock lever 41 can be easily grasped even when the heat-resistant gloves are worn. In addition, since there is sufficient space around the lock lever 41, the lock lever 41 can be easily rotated even with heat-resistant gloves.

<Preventing falling of bread baking container 28>
Next, the fall prevention effect by the lock lever 41 is demonstrated using FIG. FIG. 10 is a front view of the bakery means 30 and shows a state in the middle of setting in the heating chamber 2.

  As described above, when the bakery means 30 is attached to the bottom surface of the heating chamber 2, the drive connecting portion 31 of the bread baking container 28 is set so as to be connected to the stirring drive shaft 24 on the bottom surface of the heating chamber 2, but the two are slightly shifted. May not fit smoothly.

  As is apparent from FIG. 1, the bread baking container 28 is disposed in the vicinity of the right side wall of the heating chamber 2, so that there is a space on the left side of the bread baking container 28. If the lock lever 41 is not provided, if the bread baking container 28 is mistakenly tilted to the left, there is no support in that direction, so the bread baking container 28 falls as it is, and the bread baking container 28 is left as it is. It is also conceivable that the dough material (water, flour, etc.) set inside spills on the bottom surface of the heating chamber 2 and gets on the weight sensor 10 or enters the periphery of the stirring drive shaft 24.

  Therefore, in this embodiment, as shown in FIG. 10, when the lock lever 41 is protruded to the side of the quantity side surface of the bread baking container 28 that does not face the wall surface of the heating chamber 2 and the bread baking container 28 is inclined. The lock lever 41 can support the bread baking container 28. By comprising in this way, even if it is a case where the bread baking container 28 is accidentally inclined to the opposite side to a wall, the fall of the bread baking container 28 can be prevented.

<Ingredient input drive mechanism>
Next, using FIG. 11 to FIG. 14, an operation in which the material loading drive unit 47 operates the material container 29 will be described.

  FIG. 11 is a perspective view showing the positional relationship between the ingredient container 29 and the ingredient input drive means 47 in the main body 1. FIG. 12 is a perspective view showing the configuration of the material container 29 and the material input driving means 47. The internal configuration of the material container 29 is partially omitted, and the appearance and the material input of the material container 29 are omitted. The relationship of the drive lever 45 of the drive means 47 is mainly shown. 13 is a perspective view of the same portion as FIG. 12, but the appearance of the ingredient container 29 is partially omitted, and the relationship between the internal configuration of the ingredient container 29 and the drive lever 45 of the ingredient loading drive means 47. FIG. Further, FIG. 14 is a plan view of the material container 29.

  As described above, in the ingredient container 29, the first ingredient throwing means 43 for throwing the dry yeast 133 into the bread baking container 28 and the ingredient 135 such as raisins and nuts are thrown in. The second material input means 44 is provided. The first material input means 43 is a conical or mortar-shaped recess, and the circular opening on the bottom surface thereof is closed by the first material bottom plate 67 coming into contact with the lower side. The second material input means 44 is a rectangular recess, and the rectangular opening on the bottom surface thereof is closed by the second material bottom plate 70 coming into contact with the lower side.

  As shown in FIG. 11, ingredient charging drive means 47 is provided outside the heating chamber 2. Further, as shown in FIG. 12, the material input driving means 47 is provided with a first drive lever 45a and a second drive lever 45b that are substantially square-shaped. An ingredient container lock 76 is also provided between the first drive lever 45a and the second drive lever 45b, but the configuration and operation thereof will be described later, and the description thereof is omitted here.

  The first drive lever 45a is pivotally supported around the first drive fulcrum 72a, and a first push rod 73a is connected to the lower end. On the other hand, the tip of the first drive lever 45a is directed substantially vertically upward at the position where the first push rod 73a is lowered, and when the first push rod 73a is raised, it is turned approximately 90 ° counterclockwise. Horizontal orientation.

  The second drive lever 45b is pivotally supported around the second drive fulcrum 72b, and a second push rod 73b is connected to the lower end. On the other hand, the tip of the second drive lever 45b is directed substantially vertically upward at the position where the second push rod 73b is lowered, and when the second push rod 73b is raised, it is turned approximately 90 ° counterclockwise. Horizontal orientation.

  On the other hand, in the upper right side of the ingredient container 29, a first action hole 46a, a second action hole 46b, and an ingredient container lock receiving portion 61 are opened. And the 1st drive lever 45a, the 2nd drive lever 45b, and the material container lock 76 are arrange | positioned so that each opening may be opposed.

  As shown in FIGS. 13 and 14, the first release lever 62a is pivotally supported around the first rotation shaft 63a and is provided coaxially with the first rotation shaft 63a. Torque in the direction in which the tip of the first release lever 62a rises is applied by the torsion spring 64a, and comes into contact with the material container 29 so as to seal the first action hole 46a from the inside. A substantially vertical interlocking protrusion 65 projects from the lower surface of the first release lever 62a.

  Similarly, the second release lever 62b is pivotally supported around the second rotation shaft 63b, and the second release lever 62b is supported by a torsion spring 64b coaxially provided on the second rotation shaft 63b. Torque in a direction in which the tip of the release lever 62b rises is applied, and the release lever 62b comes into contact with the material container 29 so as to seal the second action hole 46b from the inside.

  Further, the third release lever 62c is pivotally supported around the third rotation shaft 63c, and the third release lever 62c is supported by the third torsion spring 64c provided coaxially with the third rotation shaft 63c. Torque in a direction in which the tip of the release lever 62c rises is applied and biased toward the interlocking protrusion 65 of the first release lever 62a. A part of the third rotating shaft 63c has a projection 66 extending toward the circular opening of the first material feeding means 43, and a first material bottom plate 67 forming a part of a sphere at the tip. The first material bottom plate 67 closes the circular opening of the first material input means 43 from below by the torque applied by the torsion spring 64c.

  Furthermore, as shown in FIG. 14, the substantially L-shaped fourth release lever 62d is pivotally supported around a fourth rotation shaft 63d arranged vertically. One side of the fourth release lever 62d is at a position facing the push protrusion 68 provided on the second release lever 62b, and the other side (bottom surface lock 69) is the second tool of the second material loading means 44. The bottom plate 70 is supported from below so as not to open.

<Material input operation>
Next, using FIG. 14 to FIG. 16, the first drive lever 45 a causes the dry yeast 133 to drop from the first ingredient throwing means 43, and the second drive lever 45 b throws the second ingredient. The operation of dropping the ingredient 135 from the means 44 will be described in detail.

  First, the operation | movement which drops the dry yeast 133 from the 1st material injection | throwing-in means 43 is demonstrated using the fragmentary sectional view of FIG. In FIG. 15, FIG. 15 (a) is a cross-sectional view at the position (EE) of the first material bottom plate 67 extended from the third rotating shaft 63c, and FIG. 15 (b). (C) is sectional drawing in the position (FF of FIG. 14) of the interlocking protrusion 65 of the 1st cancellation | release lever 62c, and the 3rd cancellation | release lever 62c, and it abbreviate | omits and demonstrates bread baking container 28. And

  15 (a) and 15 (b) show a state in which the material loading drive means 47 does not act on the first material loading means 43, that is, the first push rod 73a is lowered and the first drive lever 45a is heated. It is in a state of being substantially vertical outside the chamber 2. At this time, the counterclockwise torque is applied to the first release lever 62 a by the torsion spring 64 a, but the rotation of the first release lever 62 a is restricted by the upper surface of the material container 29. Further, clockwise torque is applied to the third release lever 62c by the torsion spring 64c, and clockwise torque is also applied to the first component bottom plate 67 that rotates in conjunction with the third release lever 62c. Given. At this time, the interlocking protrusion 65 of the first drive lever 45a is in a position where it does not contact the third release lever 62c. With these configurations, the first ingredient bottom plate 67 can block the circular opening on the bottom surface of the first ingredient throwing means 43 from below, and can hold the dry yeast 133 in the first ingredient throwing means 43.

  On the other hand, FIG. 15C shows a state in which the material loading drive means 47 acts on the first material loading means 43, that is, the first push rod 73a is raised and the first drive lever 45a is substantially horizontal. Thus, the first release lever 62a is being operated through the through hole 74 on the side wall surface of the heating chamber 2 and the action hole 46a of the material container 29. At this time, clockwise torque is applied to the first release lever 62a by the first drive lever 45a, and clockwise torque is also applied to the interlocking protrusion 65 provided on the lower surface of the first release lever 62c. It is done. By being pushed down by the interlocking protrusion 65, a counterclockwise torque is applied to the third release lever 62c, and the first component bottom plate 67 that rotates in conjunction with the third release lever 62c is also counterclockwise. A torque around is given. As a result, the first ingredient bottom plate 67 moves below the circular opening of the first ingredient throwing means 43, and the dry yeast 133 is thrown into the bread baking container 28 from the opened circular opening. As shown in FIG. 14, in this embodiment, by providing a hole 132 in the protrusion 66 adjacent to the first ingredient bottom plate 67, the dry yeast 133 is placed on the protrusion 66 or the first ingredient bottom plate 67. To drop quickly.

  Next, the operation of dropping the ingredient 135 from the second ingredient throwing means 44 will be described using the partial sectional view of FIG. 16 (a) and 16 (b) are cross-sectional views at the position of the push protrusion 68 (GG in FIG. 14) of the second release lever 62b. In FIG. 16 (a), bread baking is performed. The container 28 will be omitted from the description.

  FIG. 16A shows a state where the material loading drive means 47 does not act on the second material loading means 44, that is, the second push rod 73 b is lowered and the second drive lever 45 b is located in the heating chamber 2. It is in a state of being substantially vertical on the outside. At this time, counterclockwise torque is applied to the second release lever 62 b by the torsion spring 64 b, but the rotation of the second release lever 62 b is restricted by the upper surface of the material container 29. At this time, the push protrusion 68 of the second drive lever 45b is in a position where it does not contact the fourth release lever 62d. With these configurations, the second component bottom plate 70 pivotally supported around the pivot fulcrum 71 blocks the rectangular opening on the bottom surface of the second component input means 44 from below, and the fourth By supporting the bottom lock 69 of the release lever 62d so that the second material bottom plate 70 does not open, the material 135 can be held in the second material loading means 44.

  On the other hand, FIG. 16B shows a state in which the ingredient loading drive means 47 acts on the second ingredient throwing means 44, that is, the second push rod 73b is raised, and the second drive lever 45b is substantially horizontal. Thus, the second release lever 62b is being operated through the through hole 74 on the side wall surface of the heating chamber 2 and the action hole 46b of the material container 29. At this time, clockwise torque is applied to the second release lever 62b by the second drive lever 45b, and clockwise torque is also applied to the push protrusion 68 at the tip of the second release lever 62b. The pushing protrusion 68 gives a torque for rotating the fourth release lever 62d. When the fourth release lever 62d rotates and becomes in the direction indicated by the dotted line in FIG. 14 and the bottom lock 69 moves from below the second material bottom plate 70, the second tool loses its support by the bottom lock 69. The material bottom plate 70 is opened by its own weight, and the material 135 placed on the second material bottom plate 70 is put into the bread baking container 28.

  Next, the shape of the second material bottom plate 70 will be described in more detail with reference to FIG. As described above, the material container 29 is provided with the air passage 52 penetrating in the front-rear direction. Since the axial direction of the rotation fulcrum 71 of the second material bottom plate 70 is the same as the direction in which the hot air flows (the front-rear direction in the present embodiment), the second material bottom plate after the material 135 is charged. Even if 70 becomes a state opened downward, the ventilation path 52 is not closed, and the second material bottom plate 70 does not hinder the flow of hot air. In addition, when the second ingredient bottom plate 70 is opened downward, the bottom surface of the second ingredient bottom plate 70 is configured to be close to the side wall surface of the ingredient container 29. Even if the upper surface of the bread dough 57 indicated by the solid line expands to the bread upper surface 134 indicated by the broken line, the bread upper surface 134 and the second ingredient bottom plate 70 can be moved away, and the upper surface of the bread is damaged. Can be suppressed.

<Advantages of lever system>
Next, the advantage of the method of operating the first material input means 43 and the second material input means 44 using the drive lever 45 will be described.

  As shown in FIG. 15C, when the distance between the side wall surface of the heating chamber 2 and the material container 29 is L1, and the protruding distance of the first drive lever 45a from the side wall surface of the heating chamber 2 is L2, By setting L1 <L2, the material container 29 can be operated from the outside of the heating chamber 2. That is, by installing actuators such as the first material charging motor 91 and the second material charging motor 97 that are vulnerable to heat and a power transmission mechanism outside the heating chamber 2, the material container 29 in the heating chamber 2 is provided. Can be controlled at a desired timing, and the dry yeast 133 and the ingredients 135 can be fed at an appropriate timing.

  Further, as is apparent from FIGS. 15A and 15B and FIG. 16A, the drive lever 45 is usually disposed outside the heating chamber 2, so that cooking without using the bakery means 30 is performed. In addition, the drive lever 45 does not interfere with food and tableware, and does not interfere with cleaning of the heating chamber 2.

  In this embodiment, the power of the first material charging motor 91 and the second material charging motor 97 is transmitted to the release lever 62 via the tip of the drive lever 45, but the release lever 62 transmits the power. Since the force is inversely proportional to the length of the drive lever 45 protruding into the heating chamber 2, the transmission force can be increased by shortening the drive lever 45. That is, in order to increase the transmission force, it is desirable to decrease the protrusion distance L2, or synonymously to decrease the distance L1. On the other hand, if the distance L1 is too small, the possibility of rubbing the side wall surface of the heating chamber 2 when setting the bakery means 30 increases. Therefore, the distance L1 is desirably large to some extent. Therefore, in this embodiment, the distance L1 is set to 10 to 15 mm, and both the securing of an appropriate transmission force and the ease of mounting the bakery means 30 are achieved.

<Ingredient container locking mechanism>
Next, the locking mechanism of the material container 29 will be described using FIG. 17 and FIGS. 4 and 11 to 14 as appropriate.

  As shown in FIG. 12, on the outside of the heating chamber 2, an approximately container-shaped material container lock 76 is provided between the first drive lever 45a and the second drive lever 45b. The material container lock 76 is pivotally supported around the third drive fulcrum 72c, and a third push rod 73c is connected to the lower end. On the other hand, the tip of the material container lock 76 is directed substantially vertically upward at the position where the third push rod 73c is lowered, and when the third push rod 73c is raised, it is rotated approximately 90 ° counterclockwise and substantially horizontal. It becomes the direction.

  17 is a cross-sectional view of the material container lock 76 at the position (HH in FIG. 12). In FIG. 17, the bread baking container 28 is omitted. As described above, the bread baking container 28 is connected and fixed to the bottom surface of the heating chamber 2 via the drive connecting portion 31. On the other hand, the material charging drive means 47 is provided outside the heating chamber 2 along the side surface of the heating chamber 2, and the drive lever 45 acting on the material container 29 is provided near the upper end of the heating chamber 2. . Therefore, the distance dimension between the drive lever 45 and the ingredient container 29 is the position where the dimension tolerance and backlash of each member such as the heating chamber 2, the drive connecting portion 31, the bread baking container 28, the ingredient container 29 are accumulated. Even if the drive lever 45 is displaced, the necessary force is not transmitted to the release lever 62 provided in the ingredient container 29, or the ingredient container 29 and the bread baking container are caused by the reaction force of the transmitted force. There is a problem that 28 is bent and the position is shifted.

  Therefore, in order to prevent such displacement and deflection, it is preferable to provide a lock means for fixing the position of the ingredient container 29 in the vicinity of the drive lever 45 with respect to the heating chamber 2. Thus, the locking means is recessed from the inner wall of the heating chamber 2 when the user sets the bakery means 30 in the heating chamber 2, and operates the material loading drive means 47 to drop the material 135. When the user takes out the bakery means 30 after the bread is baked, the user retracts from the ingredient container 29 and heats the heating chamber 2. It is desirable to be in a position recessed from the wall surface.

  As an example of such a configuration, the material container lock 76 is provided with a lock recess 77 in the vicinity of the tip, and is pivotally supported around the third drive fulcrum 72c. When the third push rod 73c is connected and the third push rod 73c is lowered, the ingredient container lock 76 is directed substantially vertically upward, and when the third push rod 73c is raised, the ingredient container lock 76 is It rotates approximately 90 ° in the counterclockwise direction shown in the figure and becomes substantially horizontal. When the material container lock 76 is rotated in a substantially horizontal direction, the lock recess 77 is fitted into the material container lock receiving portion 61 provided in the material container 29, so that the position of the material container 29 is increased. To fix.

  That is, since the material container locking means is provided, the positional displacement and deflection of the material container are prevented, the positional relationship between the drive lever 45 and the action hole 46 of the material container 29 is kept constant, and the material charging operation is performed. There is an effect of reliably performing.

<Radio wave shielding means>
The heating cooker according to the present embodiment also supports microwave heating using the magnetron 8. Therefore, at the time of microwave heating, it is necessary to prevent microwave leakage from the vicinity of the material loading drive means 47. The radio wave shielding means for preventing microwave leakage in this embodiment will be described in detail below.

  FIG. 18 is a perspective view for explaining the configuration of the radio wave shielding means provided outside the heating chamber 2, and exemplifies the configuration for blocking radio waves in the vicinity of the first drive lever 45a and the second drive lever 45b. Yes. In the present embodiment, the drive lever 45 is configured to operate the material container 29 in the heating chamber 2 through the through hole 74 on the side wall surface of the heating chamber 2, and the drive fulcrum serving as the axis of oscillation of the drive lever 45 is provided. Since it is horizontal, the shape of the through hole 74 through which the tip of the drive lever 45 passes is a vertically long slit.

  The microwave supplied from the magnetron 8 to the heating chamber 2 during the microwave heating leaks through the through hole 74 to the material loading drive means 47 side. In this embodiment, the through hole 74 and the drive lever 45 are covered with a metal case 79 which is a radio wave shielding means so that the microwave does not leak to the outside of the main body 1.

  In addition, the lower surface of the metal case 79 requires a lower surface opening that allows the push rod 73 to pass therethrough. In order to suppress microwave leakage therefrom, the metal case 79 is made of a metal and cylindrical below the lower surface opening. The sleeve 80 was provided. When radio waves propagate through the inside of the tube, it is difficult to propagate when the cross section of the tube is small, and it does not proceed when the tube is below a certain size. By providing the sleeve 80, microwave leakage from below the metal case 79 can be effectively suppressed.

  In FIG. 18, the sleeve 80 has a cylindrical shape, but may have other shapes such as a rectangular column or a polygonal column as long as the push rod 73 is not obstructed from moving up and down. In this case, the cross-sectional dimension of the sleeve 80 may be a cross-sectional dimension equal to or smaller than the cut-off wavelength corresponding to the shape (the limit wavelength capable of suppressing the progression of radio waves). This cut-off wavelength varies depending on the cross-sectional shape. In the tube, the progress of radio waves can be suppressed by setting the dimension of one side to ½ wavelength or less. Similarly, even with a tube having a cylindrical cross section, the progression of radio waves can be suppressed by setting the diameter dimension to ½ wavelength or less. Furthermore, by making the sleeve 80 longer (for example, 15 mm or more), the progression of radio waves can be further suppressed, and microwave leakage from below the metal case 79 can be further effectively suppressed.

  Furthermore, if the upper end portion of the push rod 73 (at least the inner portion of the sleeve 80) is made of a resin, which is a dielectric, microwave leakage through the push rod 73 can be suppressed, so that microwave leakage to the outside of the main body 1 can be prevented. Can be further suppressed.

<Involute>
Next, preferred forms and operations of the drive lever 45 of the material loading drive means 47 and the release lever 62 of the material container 29 will be described with reference to FIGS. These drawings are for explaining common portions of the cross sections in the FF direction and the GG direction in FIG. 14, and the description of the configuration unique to each cross section is omitted.

  FIG. 19 shows a state in which the drive lever 45 has rotated counterclockwise and has come into contact with the release lever 62. FIG. 20 shows a state where the drive lever 45 is further rotated and the release lever 62 is pushed halfway through the operation range. FIG. 21 shows a state where the drive lever 45 has been rotated to the full operating range of the release lever 62.

  In FIG. 19, the drive lever 45 is an involute gear having the drive fulcrum 72 as the rotation center and the tip being a tooth tip circle 81 a, and the lower surface of the tip of the drive lever 45 forms an involute curve.

  The pitch circle diameter (PCD1) 82a is PCD1 = m × z1 when the module is m and the number of teeth is z1 as in the standard gear, and the tip circle 81a diameter, that is, the tip length of the drive lever 45 can be expressed by the diameter. If the tooth tip circle 81a diameter = PCD1 + 2 × m = (m + 2) × z1, only one tooth of such an involute gear is taken out and used as a part of the drive lever 45.

  Similarly, the release lever 62 is also an involute gear having the rotation shaft 63 as the rotation center and the tip being a tip circle 81b, and the top surface of the tip of the release lever 62 forms an involute curve.

  The pitch circle diameter (PCD2) 82b is PCD2 = m × z2 when the module is m and the number of teeth is z2 as in the standard gear, and the tip circle 81b diameter, that is, the tip length of the release lever 62 can be expressed by the diameter. If the tooth tip circle 81b diameter = PCD2 + 2 × m = (m + 2) × z2, only one tooth of such an involute gear is taken out and used as a part of the release lever 62.

  Here, if the inter-axis distance between the respective rotation centers of the release lever 62 and the drive lever 45 is L3, the module is m, and L3 = (z1 + z2) × m according to the meshing of the gears having the number of teeth Z1 and Z2. The tip of the drive lever 45 and the tip of the release lever 62 mesh with each other as an involute gear.

  As the meshing of the involute gear is generally well known, the meshing position 137 that is the contact point of the meshing of the two tooth profiles moves on the action line 83 that is the common tangent of the basic circle of each gear. . The action line 83 is inclined by a pressure angle α with respect to the normal line 85 with respect to the center line 84 connecting the rotation shaft 63 and the drive fulcrum 72, and the transmission force 136 is transmitted along the action line 83. Since such a transmission force 136 does not change before and after the meshing of the involute gear, the transmission force 136 is transmitted on the same action line 83 until FIG. 19, FIG. 20, and FIG. Since the operation angle ratio between the drive lever 45 and the release lever 62 is constant as the ratio of the number of teeth, that is, Z1 / Z2, the operation angle of the release lever 62 with respect to the operation angle of the drive lever 45 is constant. Stable operation with little fluctuation is obtained.

  Furthermore, as a well-known characteristic of involute gears, the ratio of the rotation angle remains constant even if the distance between the shafts of the gears changes, so that the distance between the heating chamber 2 and the material container 29 changes due to an installation error or the like. Even so, it is preferable because the release lever 62 can be stably operated by the operation of the drive lever 45.

  A preferred example of selecting a module in the involute curve used for the drive lever 45 and the release lever 62 will be described. The amount of engagement between the tip of the drive lever 45 and the tip of the release lever 62 is twice that of the module m. Therefore, by setting the module to be larger than the distance variation between the heating chamber 2 and the material container 29, there is a margin in the meshing amount, which is stable and suitable without being disengaged.

<First driving means>
Next, an example of the configuration of the first drive means 98 provided at the lower end of the first push rod 73a and driving the first push rod 73a up and down will be described with reference to FIG.

  FIG. 22 is a schematic diagram showing the configuration and operation of the first drive means 98. As shown here, in the first driving means 98, a cam 86 is rotatably supported around a rotation shaft 87, one around the cam 86 is a spiral surface 88 and the other is an upright surface 89. A plurality of claws 90 are provided along the circumference. The cam 86 is directly connected to the output shaft of the first material charging motor 91 (not shown) or connected via a reduction gear. In this embodiment, a stepping motor is used as the first material charging motor 91.

  One end of the arm 92 provided above the cam 86 is pivotally supported by a swing shaft 93, and the other end serves as a fulcrum 94 and is swingably connected to the first push rod 73a. ing. The lower side of the arm 92 protrudes in a sawtooth shape toward the cam 86, and the side close to the swing shaft 93 is a slope 95, and the side close to the fulcrum 94 is a stopper surface 96 orthogonal to the arm 92. The arm 92 is pressed toward the cam 86 by the weight of the arm 92 and the first push rod 73a.

  In the following description, the position shown in FIG. At the origin position, the arm 92 and the first push rod 73 a are at the lowest position, and the sawtooth projection of the arm 92 is placed on the inner periphery of the cam 86.

  FIG. 22B shows an initial positioning operation (initialization) in which the first ingredient charging motor 91 is reversely rotated when the power is turned on or when the operation is started. When the first material charging motor 91 is rotated counterclockwise in the drawing, the rising surface of the cam 86 and the stopper surface 96 of the arm 92 come into contact with each other, and the rotation of the cam 86 is prevented and stopped. That is, the initial rotational position of the cam 86 is specified. Since the first push rod 73a does not rise during this initialization operation, it is preferable that the dry yeast 133 is not put into the bread baking container 28 during the initialization operation.

  FIG. 22C shows the operation in progress. When the first material charging motor 91 rotates the cam 86 in the clockwise direction in the figure, the spiral surface 88 of the claw 90 provided on the cam 86 causes the arm 92 to move. The inclined surface 95 is pushed up, the arm 92 swings around the swing shaft 93, and the fulcrum 94 rises to raise the first push rod 73a. When the first push rod 73a is raised, the first drive lever 45a is swung counterclockwise as shown in FIG. 15 (c).

  FIG. 22D shows a state in which the lower end of the saw-toothed projection of the arm 92 is in contact with the tip of the claw 90 of the cam 86, and the displacement of the arm 92 is maximized, and the rising amount of the first push rod 73a. This shows a so-called top dead center where H5 is maximized. At this time, the first drive lever 45a swings to the maximum, acts on the first release lever 62a to open the first ingredient bottom plate 67, and the dry yeast 133 in the ingredient container 29 is baked. Drop into the container 28.

  FIG. 22 (e) shows a state in which the cam 86 has further rotated in the clockwise direction after passing through the top dead center. Since it falls together with the first push rod 73a toward the periphery, the first material bottom plate 67 closes the opening at the bottom of the first material input means 43 at a high speed. At this time, an impact force is applied to the first material input means 43.

  If the cam 86 is continuously rotated in the clockwise direction, the first push rod 73a can be repeatedly raised and dropped as shown in FIGS. 22 (c), 22 (d), and 22 (e). Since the dry yeast 133 is a powder or a granule, it may be difficult to fall from the mortar-shaped first ingredient charging means 43 because static electricity accumulates during the drying period. Therefore, it is effective to repeat the opening operation of the first material bottom plate 67 a plurality of times, and further, the return operation for closing the first material bottom plate 67 is performed at a high speed to release the adhesion due to static electricity. It is more preferable that the dry yeast 133 is reliably dropped.

  With the above-described configuration, if the first material input motor 91 is a stepping motor, the initial position of the cam 86 is determined by rotating it in the reverse direction (counterclockwise in the figure) and performing an initialization operation. It can be rotated further in the forward direction (clockwise in the figure) to repeat the loading operation of the dry yeast 133 a plurality of times, and the return operation of the bottom plate can be repeated at a high speed to ensure that the dry yeast 133 is There is an effect that can be dropped.

A second pin 109 is provided at a predetermined distance from the rotation shaft 106, one end of the second push rod 73b is fitted to the second pin 109, and the second gear 105 is rotated. Then, the second push rod 73b moves up and down.

  A third gear 110 provided with a third partial gear 112 that meshes with the first partial gear 104 is rotated around the rotation shaft 111 at a position substantially symmetrical to the second gear 105 with the idler gear 102 interposed therebetween. A third stopper 113a and a fourth stopper 113b are provided on both sides of the third partial gear 112 so as to mesh with the cylindrical portion 103. Further, a third pin 114 is provided at a predetermined distance from the rotating shaft 111, one end of the third push rod 73c is fitted to the third pin 114, and the third gear 110 is When it rotates, the third push rod 73c moves up and down.

  FIG. 25 is a diagram showing the configuration of the main part of the second drive means 99 in more detail, and is a perspective view seen from the direction of the arrow M in FIG. 23. For easy understanding, the second partial gear 107 is shown. Is not listed. A part of the idler gear 102 is provided with a first partial gear 104 as a drive side partial gear, and is provided, for example, only in a range in which the idler gear 102 rotates 90 °. A portion of the first partial gear 104 other than the gear shape is provided with a cylindrical portion 103 (arc-shaped portion) having a cylindrical shape with the idler support shaft 101 as a center. As shown in FIG. 25, the first partial gear 104 and the cylindrical portion 103 are arranged offset in the axial direction of the idler support shaft 101. The cylindrical portion 103 is provided continuously with the tooth tip portions of the teeth at both ends of the first partial gear 104, and the outer diameter of the cylindrical portion 103 is the diameter of the tooth tip portion of the first partial gear 104. Is equal to

  A part of the second gear 105 is provided with a second partial gear 107 as a driven side partial gear, which meshes with the first partial gear 104 provided on a part of the idler gear 102 to For example, it rotates by 90 °.

  A first stopper 108a and a second stopper 108b having arcuate surfaces recessed in an arc shape are provided on both sides in the circumferential direction with the second partial gear 107 of the second gear 105 interposed therebetween. An extension locking portion serving as a receiving portion extending radially outward from the outer periphery of the teeth of the second partial gear 107 is provided in the middle portion of the second gear 105 in the range where the second partial gear 107 is provided. 115 is provided. The first partial gear 104, the first stopper 108a, the second stopper 108b, and the extension locking portion 115 are arranged offset in the axial direction of the rotating shaft 106 (see FIG. 26). The first stopper 108a and the second stopper 108b are the cylindrical portion 103 of the idler gear 102 at the top dead center position where the second push rod 73b is most elevated and the bottom dead center position where the second push rod 73b is most lowered. The tip end portions of the respective arc surfaces are extended arc surfaces 116 a and 116 b arranged on both sides in the circumferential direction of the extension locking portion 115.

  In the present embodiment, the center of the first stopper 108 a and the extended arc surface 116 a and the second stopper 108 b and the extended arc surface 116 b provided on the second gear 105 is the position of the idler support shaft 101 of the idler gear 102. It is said that.

  A concave relief hole 117 into which the extension locking portion 115 enters when the first partial gear 104 and the second partial gear 107 mesh with each other is provided at a position facing the extension locking portion 115 of the idler gear 102. (See FIG. 25 and FIG. 26). This prevents interference between the extension lock 115 and the first partial gear 104 of the idler gear 102 when the idler gear 102 and the second gear 105 rotate.

  When the second gear 105 is rotated by approximately 90 °, which is a range in which the second partial gear 107 is engaged, the second pin 109 is rotated around the rotation shaft 106 and the second push rod 73b is raised. Or descend. In a range in which the second partial gear 107 is disengaged, the first stopper 108 a and the extended arc surface 116 a, or the second stopper 108 b and the extended arc surface 116 b are in contact with the cylindrical portion 103 of the idler gear 102. The rotation of the second gear 105 is restricted.

  In this embodiment, even if the idler gear 102 is further rotated clockwise from the position shown in FIG. 25, that is, in the direction in which the first partial gear 104 is separated from the second gear 105, the cylindrical portion 103 remains in the second position. Since the second gear 105 does not rotate, the second gear 105 remains in the locked position while being in contact with the stopper 108b and the extended arc surface 116b.

  The meshing of the third gear 110 and the idler gear 102 is the same, and rotates only while the first partial gear 104 and the third partial gear 112 mesh.

  Next, the operation of the second push rod 73b by the second driving means 99 and the operation of the third push rod 73c will be described with reference to FIG.

  FIG. 27 is a schematic view showing a series of operations of the second driving means 99, and the spur gear on the outer periphery of the idler gear 102 is omitted.

  FIG. 27A shows that the second push rod 73b and the third push rod 73c together with the second pin 109 and the third pin 114 are at the lowest bottom dead center position, and the second push rod 73b The connected second drive lever does not act on the material container 29 as shown in FIG. 16A, and the material container lock 76 connected to the third push rod 73c is indicated by a broken line in FIG. As shown, the ingredient container 29 is not locked.

  Here, although not shown, the idler gear 102 is in contact with a stopper (not shown) in the direction of the broken arrow, which is reverse to the operation direction. At the start of the cooking operation, the initial position of the idler gear 102 is determined by rotating in the direction of the broken line arrow at the position shown in FIG.

  FIG. 27B shows a state in which the second material charging motor 97 is driven and the idler gear 102 is rotated about 90 ° counterclockwise in the drawing. The first partial gear 104 meshes with the third partial gear 112, the third gear 110 rotates in the clockwise direction in the figure, the third pin 114 is rising, and the third push rod 73c (not shown) also rises. I am doing.

  FIG. 27 (c) shows a state where the idler gear 102 is further rotated to about 180 ° in the counterclockwise direction shown in the figure. Engagement between the first partial gear 104 and the third partial gear 112 is completed, and the cylindrical portion 103 provided on the idler gear 102 is in contact with the extended arcuate surface 118a while the third partial gear 112 is rotated about 90 °. The third gear 110 is locked by coming into contact with the third stopper 113a, and the third pin 114 is at the highest dead center position.

  In this state, the third push rod 73c is raised most, and the ingredient container lock 76 rotates toward the inside of the heating chamber 2 as shown by the solid line in FIG. The material container 29 is locked by fitting with the container lock receiving portion 61.

  In FIG. 27 (d), the idler gear 102 is further rotated to about 270 °. The third pin 114 remains at the top dead center position, but the first partial gear 104 meshes with the second partial gear 107 of the second gear 105 and the second gear 105 rotates clockwise, The second pin 109 is rising, and the second push rod 73b (not shown) is also rising.

  FIG. 27 (e) shows a state in which the idler gear 102 is further rotated in the counterclockwise direction shown in the drawing until it comes into contact with a rotation stopper (not shown) slightly before about 360 °. The meshing between the first partial gear 104 and the second partial gear 107 is completed, and the cylindrical portion 103 provided on the idler gear 102 is in contact with the extended arcuate surface 116a while the second partial gear 107 is rotated about 90 °. The second gear 105 is locked by coming into contact with the first stopper 108a, and the second pin 109 is at the highest dead center position.

  In this state, the second push rod 73b is most elevated, and the second drive lever 45b rotates toward the inside of the heating chamber 2 as shown in FIG. The ingredients 135 such as raisins and nuts that have been put into the second ingredient feeding means 44 by acting on the lever 62b are dropped into the bread baking container 28.

  When the material charging is completed, the second material charging motor 97 is reversed to rotate the idler gear 102 in the clockwise direction in the state shown in FIG. 27E until the state shown in FIG. The push rod 73b and the third push rod 73c are lowered to the bottom dead center, and the second drive lever 45b and the material container lock 76 are returned to complete a series of operations.

  With the above configuration, the action of the second drive lever 45 b causes the action of dropping the ingredient 135 such as raisins and nuts and the action of fixing the ingredient container 29 by the ingredient container lock 76 to have only one action. Since it can be realized only by the second material charging motor 97 which is a motor, there is an effect of reducing the mounting space and cost.

  In the above embodiment, the second material charging motor 97 has both the second drive lever 45b and the material container lock 76. However, the mounting rigidity and positional accuracy of the material container 29 are sufficient. In some cases, the material container lock 76 may be omitted.

<Effect of the heating cooker of a present Example>
According to the present embodiment, the bakery means provided with the ingredient container capable of dropping the ingredient set in advance on the bread baking container can be installed in the heating chamber from the main body opening provided on the front surface of the main body. In addition, since there is provided an ingredient loading drive means that can penetrate the heating chamber from the outside of the heating chamber and act on the ingredient container on the heating chamber side to throw the ingredients into the bread baking container at a predetermined time. , A microwave oven, an oven, a bakery capable of baking bread with ingredients, and a cooking device having three functions.

  Further, according to this embodiment, the height of the bakery means, that is, the total height of the bread baking container and the material container is configured to be smaller than the height of the front opening of the heating chamber. A cooking device that is easy to attach and detach and can be used can be provided.

  In addition, according to the present embodiment, since the handle serving as a handle is provided on the front side of the side surface of the bread baking container, it is possible to provide an easy-to-use cooking device in which the bakery means can be easily attached and detached from the front opening.

  Further, according to the present embodiment, the table plate placed on the weight sensor is removed, and the stirring drive shaft that rotationally drives the stirring blades in the bread baking container is exposed so that it can be seen, and then the bread baking container is set. Therefore, there is an effect that the bread baking container is easy to set.

  In addition, according to the present embodiment, the mounting guide that is set on the bottom surface of the heating chamber along the side wall of the heating chamber is provided so as to cover the weight sensor. In addition to being high, it is guided to the set position of the bread baking container by moving the drive connecting portion provided on the bottom face of the bread baking container along the mounting guide, so that the bread baking container is easy to attach.

  In addition, according to the present embodiment, a gap facing the front-rear direction of the heating chamber is provided between the upper surface of the bread baking container and the bottom surface of the ingredient container, and the hot air passes along the gap. Since the hot air directly heats the bread dough surface, the dough is reliably heated, and a baked bread can be baked.

  In addition, according to the present embodiment, the end surface of the ingredient container is arranged closer to the main body back side than the end surface of the upper surface of the bread baking container on the main body back side, so that by appropriately inhibiting the flow rate of hot air In addition, a baked bread having a more uniform baking color and swelling can be obtained.

  Further, according to this embodiment, the bakery means provided with the ingredient container is set close to the inside of the side wall of the heating chamber, the ingredient charging drive means is provided outside the heating chamber side wall, and the ingredient charging drive means is driven. Since the lever penetrates the heating chamber from the outside of the heating chamber and acts on the inner material container to drop the ingredients into the bread baking container, there is an effect that the bread containing the ingredients can be baked.

  In addition, according to the present embodiment, the bread baking container is attached to the heating chamber by rotating the rotating claw via the lock lever without twisting the bread baking container. Since the same posture is maintained after being locked, the positional relationship of the working holes connected to the material charging drive means is kept constant, so that the material charging operation is reliable.

  Moreover, according to the present Example, since it was set as the structure which makes a lock lever protrude in the side which faced the inner side of the heating chamber, the fall of a bread baking container can be prevented with a lock lever.

  Further, according to the present embodiment, the drive lever that penetrates the heating chamber from the outside of the heating chamber and acts on the inside material container to drop the material into the bread baking container does not act on the material container. It is preferable to arrange the space outside the side wall so as not to make a business trip to the inside of the heating chamber, because it does not obstruct food in and out and cleaning.

  Further, according to the present embodiment, the actuator of the material charging drive means is provided in the low temperature machine room below the heating chamber, and the drive lever for dropping the material into the bread baking container is provided near the upper end of the heating chamber. Since the actuator and the drive lever are connected by the push rod, the actuator can act on the ingredient container via the drive lever while being kept at a low temperature, and the ingredient can be dropped into the bread baking container.

  Further, according to the present embodiment, the second ingredient bottom plate that is opened when the ingredient is introduced is opened along the inner wall surface of the ingredient container, so that the second ingredient bottom plate is opened. Later, the air passage is not blocked and hot air is not obstructed, and further, the lowered tip of the second material bottom plate is located in the peripheral portion where the amount of swelling of the bread is small, so that even if the bread swells, it will not be damaged.

  Further, according to the present embodiment, since the material container locking means for locking the material container is provided, the position of the drive lever and the working hole of the material container is prevented by preventing the displacement and deflection of the material container. It is possible to keep the relationship constant and reliably perform the material charging operation.

  Further, according to the present invention, the drive lever covers the slit penetrating the heating chamber with the metal case, and the metal sleeve is provided along the push rod for transmitting the driving force, and further inserted into the metal sleeve of the push rod. Since the portion to be made is made of a resin which is a dielectric, leakage of radio waves can be prevented during microwave heating.

  In addition, according to the present embodiment, the engaging portion of the drive lever provided in the material loading drive mechanism and the release lever provided in the material container are arranged in an involute curve so that the gears mesh with each other. Since the operation angle of the release lever is constant with respect to the operation angle of the drive lever, there is an effect that a stable operation can be obtained with little fluctuation in the operation of the release lever. Further, even if the distance between the drive lever and the release lever varies, the ratio of the rotation angles remains constant, so that a more stable operation can be obtained.

  In addition, according to the present embodiment, the first ingredient in which the dry yeast 133 is thrown in via the push rod by a cam provided with a plurality of claws along the circumference, one of which is a spiral surface and the other is an elevation surface. Since the charging means is configured to operate, the charging operation of the dry yeast 133 can be repeated continuously a plurality of times, and the dry yeast 133 can be reliably dropped by applying an impact with a high speed return operation of the bottom plate. There is.

  In addition, according to the present embodiment, the operation of the second material input means and the material container locking means can be realized by only the second material input motor, which is only one motor, so that the mounting space can be reduced. In addition, there is an effect of cost reduction.

<Falling noise reduction>
The cooking-by-heating machine of Example 2 is demonstrated using FIG. Note that the description of the points in common with the first embodiment will be omitted.

  In the first driving means 98 using the cam 86 and the arm 92 described with reference to FIG. 22, the arm 92 and the first push rod 73a are moved from the top dead center during the closing operation shown in FIG. Since the height H5 is dropped at once, a drop impact sound is generated.

  On the other hand, as apparent from FIGS. 15B and 15C, the first drive lever 45a acts on the first release lever 62a because the first push rod 73a is raised to the maximum extent.
