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 this embodiment, electromagnetic actuators (first solenoid 91 and second solenoid 101) functioning as actuators for the material loading drive means 47 are disposed in the machine chamber 5 that is cooler than the heating chamber 2, and here, The generated driving force 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.

<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 is provided at the upper left end of the bread baking container 28 in the figure, and a first recess 49 is provided at the upper right end of the figure.

  Further, a second recess 50 is provided at the left end of the ingredient container 29 in the figure, and a second protrusion 51 is provided at the right end in the figure. Then, the first container 48 and the second recess 50 are made to correspond to each other, and the first recess 49 and the second protrusion 51 are made to correspond to each other so that the ingredient container 29 faces the bread baking container 28 in the wrong direction. It was made impossible to place it.

  Further, an air passage 52 through which the hot air 53 can flow is provided in the front-rear direction of the lower end of the ingredient container 29 so that the hot air 53 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. Note 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 53 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 and is bread baking. While the container 28 is heated from the side surface, the bread is baked by being blown onto the upper surface of the bread dough 57 in the bread baking container 28 through the ventilation path 52.

  FIG. 27 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. 27A, 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 ventilation path 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. 27 (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. When the bakery means 30 is mounted on the bottom surface of the heating chamber 2 in accordance with the mounting guide 36 as shown in FIG. 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 hook-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 set to about 1/3 to 1/4 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. 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 is applied to 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 on the side of the both sides 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.

  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, a first action hole 46 a and a second action hole 46 b are opened in the upper right side of the ingredient container 29. And the 1st drive lever 45a and the 2nd drive lever 45b 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 rotation shaft 63c has a third protrusion 66 extending toward the circular opening of the first material feeding means 43, and a first tool forming a part of a sphere at the tip thereof. A material bottom plate 67 is provided, and 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 demonstrates bread baking container 28 abbreviate | omitting. 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 third protrusion 66 adjacent to the first ingredient bottom plate 67, the dry yeast 133 is made to have the third protrusion 66 and the first protrusion 66. It was made to fall quickly from the top of the ingredient bottom plate 67.

  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 projection 68 (GG in FIG. 14) of the second release lever 62b. In FIG. The firing container 28 will be omitted for explanation.

  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 direction as the direction in which the hot air 53 flows (in this embodiment, the front-rear direction), the second material after the material 135 is charged. Even if the bottom plate 70 is opened downward, the ventilation path 52 is not closed, and the second material bottom plate 70 does not hinder the flow of the hot air 53. 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 solenoid 91 and the second solenoid 101 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 operated at a desired timing. And control which throws in dry yeast 133 and ingredients 135 at an appropriate timing is realizable.

  Further, as apparent from FIGS. 15A and 15B and FIG. 16A, the drive lever 45 is normally 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 first solenoid 91 and the second solenoid 101 is transmitted to the release lever 62 via the tip of the drive lever 45, but the force transmitted by the release lever 62 is heated. Since it is inversely proportional to the length of the drive lever 45 protruding into the 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.
<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. 17 is a perspective view for explaining the configuration of the radio wave shielding means provided outside the heating chamber 2, and exemplifies a configuration for blocking radio waves in the vicinity of the first drive lever 45 a and the second drive lever 45 b. 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 driving fulcrum 72 serving as the swing axis of the drive lever 45. The horizontal shape of the through hole 74 through which the tip of the drive lever 45 is passed becomes a vertically long slit shape.

  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. 17, the sleeve 80 has a cylindrical shape, but may have other shapes such as a quadrangular column or a polygonal column as long as the push rod 73 is not hindered 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. 18 shows a state in which the drive lever 45 has rotated counterclockwise and has come into contact with the release lever 62. FIG. 19 shows a state where the drive lever 45 is further rotated and the release lever 62 is pushed halfway through the operating range. FIG. 20 shows a state in which the drive lever 45 has been rotated to the full operating range of the release lever 62.

  In FIG. 18, the drive lever 45 is an involute gear having the drive fulcrum 72 as the rotation center and the tip of the drive lever 45 being a tooth tip circle 81a.

  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 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 it is generally well known that the involute gear meshes, the meshing position 137, which is the contact point between the two tooth profile meshes, moves on the action line 83, which is the common tangent of the base 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. Such a transmission force 136 does not change before and after the engagement in the case of the engagement of the involute gear, so that the transmission force 136 is transmitted on the same action line 83 until FIGS. 18, 19, and 20. 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 fluctuation amount between the heating chamber 2 and the material container 29, a margin is generated in the meshing amount, which is stable and suitable without being disengaged.
<First driving means>
Next, with reference to FIGS. 21 and 22, an example of the configuration of the first driving means 88 that is provided at the lower end of the first push rod 73a and drives the first push rod 73a up and down will be described. The configuration and operation of the second drive unit 89 indicated by the broken line in FIG. 21 are the same as those of the first drive unit 88, and thus individual descriptions are omitted.

  FIG. 21 is a schematic diagram showing the configuration and operation of the first driving means 88. FIG. 21A shows a non-energized state where the first solenoid 91 is not operating. As shown in FIGS. 15A, 15B, and 16A, the first push rod 73a is lowered. Since the first drive lever 45 a is substantially vertical outside the heating chamber 2, the ingredient loading drive means 47 does not act on the first ingredient throwing means 43. FIG. 21B shows an energized state in which the first solenoid 91 is operating, and as shown in FIGS. 15C to 16B, the first push rod 73a is raised, and the first Since the drive lever 45a is substantially horizontal, the first release lever 62a is 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, and the material loading drive means 47 is moved to the first position. It is in a state in which it acts on one ingredient throwing means 43. FIG. 22 is a view of the first driving means 88 as seen from the K direction of FIG.

  As shown in FIGS. 21 and 22, the first solenoid 91 is supported so as to be movable along a stator 92 in which a coil is wound around a cylindrical hole, and a cylindrical hole 94 provided in the stator 92. And a plunger 93 which is a magnetic moving element, and a driving force is generated by attracting the plunger 93 to the stator 92 side by a magnetic force generated when the coil of the stator 92 is energized.

  As shown in FIG. 21, in the first driving means 88, a plunger 93 of the first solenoid 91 is attached to one end 97 of a substantially crank-shaped bell crank 96 that is rotatably supported around a rotating shaft 95. The lower end of the first push rod 73 a is rotatably supported around the rotation shaft 95 at the other end 98 of the bell crank 96. As shown in FIG. 22, in the present embodiment, one end 97 of the bell crank 96 is bifurcated and sandwiched with a plunger 93 so as to be rotatably supported by a pin 99.

  In the non-energized state of FIG. 21 (a), the plunger 93 is urged by the spring 100 in a direction away from the stator 92 (upper left direction in the figure) and cooperates with the weight of the first push rod 73a in the bell. A clockwise rotational force is applied to the crank 96 around the rotation shaft 95 to hold the first push rod 73a at the lowest position. As described above, in this state, the material input driving means 47 does not act on the first material input means 43. In FIG. 21A, the plunger 93 protrudes from the stator 92 to the maximum, and the protruding amount at that time is the maximum value P1.

  The energized state of FIG. 21B shows a state where the coil of the stator 92 is energized, and the plunger 93 is attracted and moved by the stator 92 and rotates the bell crank 96 against the spring 100 force. The first push rod 73a is lifted by rotating counterclockwise around the shaft 95, and the material loading drive means 47 becomes the first material loading means 43 as shown in FIG. The dry yeast 133 is put into the bread baking container 28 by acting. In FIG. 21B, the plunger 93 is most attracted to the stator 92, and the protrusion amount at that time is the minimum value P3.

  By repeating energization and cutting of the coil of the stator 92 a plurality of times, the first push rod 73a can be raised and dropped repeatedly. 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.

  Here, the solenoid generally has an elongated shape in the moving direction of the plunger 93. If the stroke, which is the amount of movement of the plunger 93, is about 10 mm to 15 mm, the total length when the stator 92 is not energized is, for example, about 60 to 70 mm, and the first solenoid 91 and the second solenoid 101 If the solenoids are arranged in series and arranged in series, they cannot be placed close to each other, but by arranging the solenoids to be inclined, the stator 92 of the first solenoid 91 and the bell crank 96 of the second drive means 89 are vertically moved. Since the distance between the first driving means 88 and the second driving means 89 can be shortened, the size can be reduced. FIG. 21A shows an example of the arrangement of the second driving means 89 with broken lines.

  In the present embodiment, the plunger 93 of the first solenoid 91 is arranged to be inclined, and the movement direction of the plunger 93 is converted into the vertical movement of the first push rod 73a by the substantially bell-shaped bell crank 96. However, the present invention is not limited to such a configuration. For example, the solenoid plunger 93 is arranged so as to move in the same vertical direction as the moving direction of the first push rod 73a. The plunger 93 and the first push rod 73a may be directly connected without providing the bell crank 96, and the first push rod 73a may be directly operated by the plunger 93.

Alternatively, the plunger 93 and the first push rod 73a are both arranged in the vertical direction, and the bell crank 96 is a straight line arranged substantially horizontally rather than substantially in the shape of a bellows. And the first push rod 73a is connected to the other end across the rotation shaft 95, and the downward movement of the plunger 93 is converted to the upward movement of the first push rod 73a. May be.
<Features and effects of solenoid>
In this embodiment, the solenoids 91 and 101 are used as the actuators for driving the first driving means 88 and the second driving means 89. Therefore, in a situation where no power is supplied, the spring 100 force and the weight of the push rods 73a and 73b are used. The push rods 73a and 73b can be held at the lowest lowered position. Furthermore, even if the power supply to the solenoids 91, 101 is suddenly cut off during operation due to a power supply being accidentally pulled out from the outlet during the operation of the solenoids 91, 101, the solenoid is turned off at the same time. Since the driving force by 91 and 101 is not generated, the push rods 73a and 73b return to the lowest position by the spring 100 force and the weight of the push rods 73a and 73b thereafter.

That is, as shown in FIG. 15 (c) or FIG. 16 (b), the drive lever 45 is inserted into the working hole 46 provided in the ingredient container 29, and the first release lever 62a or the second release lever 62b. Even during the operation, the push rods 73a and 73b are lowered as the current is cut off, and the drive lever 45 is moved to the position shown in FIGS. 15 (a), 15 (b) to 16 (a), that is, the drive. Since the tip of the lever 45 faces substantially vertically upward and returns to the retracted position outside the through hole 74 provided in the heating chamber 2, the drive lever 45 also hinders the operation even when the bakery means 30 is subsequently taken out, for example. The handleability is good.

<Effect of the heating cooker of a present Example>
According to the present embodiment, the bakery means 30 provided with the ingredient container 29 on which the preset ingredient can be dropped and put on the bread baking container 28 is provided from the main body opening provided on the front surface of the main body 1 to the inside of the heating chamber 2. Furthermore, it penetrates the heating chamber 2 from the outside of the heating chamber 2 and acts on the material container 29 inside the heating chamber 2 to put the ingredients into the bread baking container 28 at a predetermined time. Since the ingredient charging drive means 47 is provided, a cooking device having three functions of a microwave oven, an oven, and a bakery capable of baking ingredient-containing bread can be provided.

  Further, according to this embodiment, the height of the bakery means 30, that is, the sum of the height of the bread baking container 28 and the height of the ingredient container 29 is configured to be smaller than the height of the front opening 42 of the heating chamber 2. In addition, it is possible to provide an easy-to-use cooking device in which the bakery means 30 can be easily attached and detached.

  In addition, according to the present embodiment, the handle 40 serving as the handle 4 is provided on the front side of the side surface of the bread baking container 28, so that the bakery means 30 can be easily attached and detached from the opening on the front surface and an easy-to-use cooking device can be provided. .

  Further, according to the present embodiment, the table plate 11 placed on the weight sensor 10 is removed, and the stirring drive shaft 24 that rotationally drives the stirring blade 27 in the bread baking container 28 is exposed so that it can be visually observed. Since the bread baking container 28 is set, there is an effect that the bread baking container 28 is easy to set.

  Further, according to the present embodiment, since the mounting guide 36 set on the bottom surface of the heating chamber 2 along the side wall inside the heating chamber 2 is provided so as to cover the weight sensor 10, the weight sensor 10 is damaged when the bread baking container 28 is attached. The bread baking container 28 is guided to the set position of the bread baking container 28 by moving the drive connecting portion 31 provided on the bottom surface of the bread baking container 28 along the mounting guide 36. 28 is easy to install.

  Further, according to the present embodiment, a gap is provided between the upper surface of the bread baking container 28 and the bottom surface of the ingredient container 29 so as to face the front-rear direction of the heating chamber 2, and the hot air 53 passes along the gap. Therefore, since the hot air 53 directly heats the bread dough surface 56, the dough is surely heated, and a baked bread can be baked.

  In addition, according to the present embodiment, since the end surface of the ingredient container 29 is arranged closer to the back side of the main body than the end surface of the upper surface of the bread baking container 28 on the back side of the main body, the flow rate of the hot air 53 is appropriately inhibited. By doing so, a baked bread having a more uniform baking color and swelling can be obtained.

  In addition, according to the present embodiment, the bakery means 30 having the ingredient container 29 is set in the vicinity of the inside of the side wall of the heating chamber 2, and the ingredient input driving means 47 is provided on the outside of the side wall of the heating chamber. Since the drive lever 45 of the drive means 47 penetrates the heating chamber 2 from the outside of the heating chamber 2 and acts on the inner material container 29 to drop the material into the bread baking container 28, the material There is an effect that the bread can be baked.

  Further, according to the present embodiment, the bread baking container 28 is mounted on the heating chamber 2 by rotating the rotation claw 60 via the lock lever 41 without twisting the bread baking container 28, Since the firing container 28 maintains the same posture after being attached and detached and locked, the positional relationship of the action holes 46 connected to the material input drive means 47 is kept constant, so that the material input operation is reliable.

  Moreover, according to the present Example, since the lock lever 41 protruded to the side facing the inside of the heating chamber 2, the bread baking container 28 can be prevented from falling by the lock lever 41.

  In addition, according to the present embodiment, the drive lever 45 that penetrates the heating chamber 2 from the outside of the heating chamber 2 and acts on the inner material container 29 to drop the material into the bread baking container 28 includes: While it does not act on the material container 29, it is preferable to arrange it outside the side wall so as not to travel inside the heating chamber 2, so that it does not interfere with food in and out and cleaning.

  Further, according to the present embodiment, the actuator of the material charging drive means 47 is provided in the low temperature machine room 5 below the heating chamber 2, and the drive lever 45 for dropping the material into the bread baking container 28 is heated. Since the actuator and the drive lever 45 are connected by the push rod 73 provided near the upper end of the chamber, the actuator acts on the material container 29 via the drive lever 45 while the temperature is kept low, and the material is baked. It can be dropped into the container 28.

  Further, according to the present embodiment, the second ingredient bottom plate 70 that is opened when the ingredient is introduced is opened along the inner wall surface of the ingredient container 29, so that the second ingredient bottom plate 70 is opened. Even after opening, the air passage 52 is not blocked and the hot air 53 is not obstructed, and the lowered tip of the second material bottom plate 70 is located in the peripheral portion where the amount of swelling of the bread is small. It will not hurt.

  Further, according to the present embodiment, the drive lever 45 covers the slit penetrating the heating chamber 2 with the metal case 79, the metal sleeve 80 is provided along the push rod 73 that transmits the driving force, and the push rod 73 is further provided. Since the portion inserted inside the sleeve 80 is made of a resin, which is a dielectric, leakage of radio waves can be prevented during microwave heating.

Further, according to the present embodiment, the meshing portions of the drive lever 45 provided in the material loading drive mechanism and the release lever 62 provided in the material container 29 are involute curves to form a gear mesh. Since the operation angle of the release lever 62 with respect to the operation angle of the drive lever 45 is constant, there is an effect that a stable operation can be obtained with little fluctuation in the operation of the release lever 62. Further, even if the distance between the drive lever 45 and the release lever 62 varies, the ratio of the rotation angles remains constant, so that a more stable operation can be obtained.
<Effect when power is cut off by solenoid>
Even when the power supply to the solenoids 91 and 101 is suddenly cut off due to a power failure by mistake during operation of the solenoids 91 and 101 or due to a power failure or the like, the driving force by the solenoids 91 and 101 is cut off simultaneously. Then, since the push rods 73a and 73b move to the lowest position by the spring 100 force and the weight of the push rods 73a and 73b, the energization is cut off and the heating chamber 2 is penetrated from the outside of the heating chamber 2 after that. The drive lever 45 that acts on the inner ingredient container 29 to drop the ingredient into the bread baking container 28 is located outside the side wall so as not to travel inside the heating chamber 2. This is suitable because it does not interfere with the removal and entry and cleaning.

<Hanging from the top>
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.

  FIG. 28 is a partial cross-sectional view of the heating cooker according to the second embodiment as viewed from the front. The difference from the first embodiment is that the ingredient container 29 is not placed on the upper surface of the bread baking container 28 and used as the bakery means 30, but a side wall rail 120 extending in the front-rear direction is provided inside the side wall of the heating chamber 2. And the top surface rail 121 suspended from the top surface of the heating chamber 2, and the material container 29 is configured to be suspended along the upper side surface of the heating chamber 2 by the side wall rail 120 and the top surface rail 121. .

  In this configuration, first, only the bread baking container 28 is set first, and then the ingredient container 29 is inserted from the opening and slid toward the back side along the side wall rail 120 and the top rail 121. set.

  The bread baking container 28 is connected to the stirring drive shaft 24 via the drive connecting portion 31 as in the first embodiment. Since the bread baking container 28 and the material container 29 are not integrated but separated, when the bread baking container 28 is set in the main body 1, only the rotating claw 60 is rotated as shown in FIGS. The claw may be provided as a part of the drive connecting portion 31, and the whole bread baking container 28 may be rotated to engage the claw and lock to the bottom surface of the heating chamber 2. There may be.

  In such a configuration, the bread baking container 28 rotates with respect to the vertical axis and tilts before locking, but the ingredient container 29 is set in the heating chamber 2 without the bread baking container 28. Since the positional relationship between the release levers 62a and 62b provided on the container 29 and the drive levers 45a and 45b is maintained, there is an effect that the dropping operation of the ingredient 135 is stably performed.

<Vacuum container>
The cooking-by-heating machine of Example 3 is demonstrated using FIG. Note that the description of the points in common with the first embodiment will be omitted.

  FIG. 29 is a partial cross-sectional view of the heating cooker provided with the vacuum container 122 as viewed from the front. The difference from the first embodiment is that the interior of the heating chamber 2 is not the bakery means 30 but the vacuum container 122 that can maintain a vacuum state in which the interior is previously depressurized, and the vacuum container 122 further communicates with atmospheric pressure. This is to provide a vacuum release lever 123 that releases the negative pressure inside the vacuum vessel 122. The cooking device further includes a vacuum release drive lever 124 that operates from the outside of the heating chamber 2.

  The vacuum release lever 123 is pivotally supported around a fulcrum 125. One end is provided with a flexible rubber stopper 126, for example, and a hole provided in the vacuum vessel 122 is sealed to maintain an internal vacuum. To do. The other end is a working end 127. If the working end 127 is moved downward in the figure, the vacuum release lever 123 swings, the stopper 126 comes off, and air enters the inside of the vacuum vessel 122. Atmospheric pressure.

  The vacuum release drive lever 124 is configured to act on the action end 127 of the vacuum release lever 123 inside the heating chamber 2 to release the negative pressure in the vacuum vessel 122. In this embodiment, after the food is set in the vacuum container 122, the inside is decompressed by, for example, a vacuum pump (not shown), then set in the heating chamber 2, and cooking is started after cooking is started. The vacuum can be released at a predetermined point in the process.

<Cooking container>
The cooking-by-heating machine of Example 4 is demonstrated using FIG. Note that the description of the points in common with the first embodiment will be omitted.

  FIG. 30 is a partial cross-sectional view of the heating cooker provided with the cooking container 129 as seen from the front. The difference from the first embodiment is that the heating chamber 2 is set not in the bakery means 30 for baking bread but in the cooking means 128, and in place of the bread baking container 28, a cooking container 129 is provided. 29 is an ingredient seasoning container 130 provided with first ingredient throwing means 43 and second ingredient throwing means 44 instead of 29.

  In this embodiment, it is the seasoning that is set in the first ingredient input means 43. For example, the boiled material set in the cooking container 129 is stirred and cooked until cooking is completed. The seasoning preset in the first ingredient charging means 43, such as salt or spice, is dropped into the cooking container 129 at a predetermined point in time, and heating and stirring are performed for a predetermined time to complete cooking. A cooker may be used.

  In addition, the second material input means 44 is set in advance with materials suitable for input into the cooking container 129 in the latter half of cooking or just before the end, for example, materials that are vulnerable to heat and stirring. Then, it may be configured to drop into the cooking container 129. Alternatively, in the case of cooking that does not require agitation, only the drop-in of the seasoning or ingredients 135 may be performed after a predetermined time.

  Alternatively, the cooking vessel 129 may be configured to simply be placed in the heating chamber 2 without including the drive connecting portion 31 and the stirring blade 27.

<Phase control circuit>
The heating cooker of Example 5 is demonstrated using FIGS. 31-35. Note that the description of the points in common with the above-described embodiment will be omitted. In the fifth embodiment, the load applied to the solenoid 91 and the current waveform applied to the coil of the stator 92 will be described by taking the first driving means 88 as an example. Since the current waveform applied to the second driving means 89 is also the same, the description is omitted.

FIG. 31 is a diagram showing an outline of the relationship between the amount of movement of the plunger 93 and the load when the solenoid 91 shown in FIG. 21 is operated. FIG. 32 is a block diagram showing a schematic configuration of the drive circuit 152 of the solenoid 91, and FIG. 33 is a more detailed circuit block diagram. FIG. 34 shows current waveforms in various parts of the circuit in the circuit block diagram shown in FIG. FIG. 35 is a diagram illustrating electric power applied when the solenoid 91 is driven. The horizontal axis of FIG. 31 shows the amount of protrusion of the plunger 93 from the stator 92 in the solenoid 91. As explained in FIG. 21, the maximum value is P1 when no power is supplied, and the minimum value is the maximum suction position. P3. The vertical axis indicates the load applied to the plunger 93. The amount of protrusion when the solenoid 91 is not energized is P1, and the load is F1 in total of the spring 100 force and the weight of the push rod 73a. It is the minimum state. Here, when the coil of the stator 92 of the solenoid 91 is energized, the plunger 93 is attracted toward the stator 92 and moves toward the left side of the arrow in FIG. 31 while pushing up the push rod 73a.

  Here, as described with reference to FIG. 15, the drive lever 45 a rotates from the position where the tip is substantially vertically upward toward the inside of the heating chamber 2 as the push rod 73 a is lifted. For example, the drive lever 45a is simply rotated without any load during the range in which it rotates about 75 °, for example, between P1 and P2 in FIG. Just do it. Therefore, during this range (a), only the load for extending the spring 100 is increased, and it becomes F2 at the P2 position.

  On the other hand, when the tip of the drive lever 45a comes into contact with the first release lever 62a at the position P2, the first release lever 62a and the third release lever 62c provided inside the material container 29 are placed at the tip of the drive lever 45a. (B) is rapidly applied, and the load increases rapidly from F2 to F3. Further, in the range (c) in which the plunger 93 is sucked and rotated by, for example, about 15 ° until reaching the maximum suction position P3, it is the bottom surface of the first material feeding means 43 on which the dry yeast 133 is placed. In order to open the first ingredient bottom plate 67 and to put the dry yeast 133 into the bread baking container 28, the torsion springs 64a and 64c provided on the rotary shafts 63a and 63c of the spring 100 and the release lever 62, etc. The driving load reaches the maximum value F4.

  That is, as shown in FIG. 31, the material loading drive means 47 of this embodiment has a light load from the P1 position where the plunger 93 is not energized to the P2 position in the vicinity of the maximum suction position, while the P2 position To the maximum suction position P3.

  Because of such load characteristics, when power that can generate the maximum load F4 is continuously supplied to the solenoid 91 from the beginning of energization, since the load is light during the range (a), most of the power Since the first push rod 73a is accelerated and converted into kinetic energy, the moving speed of the plunger 93 and the first push rod 73a at the P2 position is high, and the tip of the drive lever 45a is the first at the P2 position. The collision noise generated when the material 135 and the dry yeast 133 are thrown in after moving to the P3 position after colliding with the release lever 62a is large, and the impact applied to the release lever 62a and other parts as well as the drive lever 45a The force also increases, and there is a risk of component damage due to impact stress. Therefore, it is possible to reduce the impact force, in other words, to control the power applied to the solenoid 91 so as to generate the maximum load F4 at the maximum suction position P3 while reducing the speed of the plunger 93 at the P2 position. It is valid.

  A preferred control circuit for the solenoid 91 described above will be described in detail with reference to FIGS. In the block diagram of FIG. 32, power is adjusted by a phase control circuit 158 connected to a commercial power supply of 100 V, 50 Hz to 60 Hz, then full-wave rectified by a rectifier circuit 159, smoothed by a smoothing circuit 160, and supplied to a solenoid 91. Applied and suction driven.

  Next, the circuit block diagram of FIG. 33 and the current waveform diagram of FIG. 34 will be described in detail. The phase control circuit 158 includes a commercial frequency detection circuit 161, a control microcomputer 150, and a phototriac coupler 162. The phototriac coupler 162 is an element that controls a triac, which is a so-called switching element whose output side can turn on and off an alternating current, by inputting an optical signal to the LED, and turns on and off the commercial power supply by a signal from the microcomputer 150. The rectifier circuit 159 performs full-wave rectification of the sine wave using, for example, a single-phase bridge circuit using four diodes. The smoothing circuit 160 is, for example, an electrolytic capacitor, and reduces the pulsation after full-wave rectification to bring it closer to a constant voltage DC waveform.

  Here, taking the case where the commercial power supply is 50 Hz as an example, the current waveform at the position of FIG. 33A is a sine wave 163 having a wavelength of 20 ms as shown in FIG.

  The commercial frequency detection circuit 161 detects this frequency and sends it to the control microcomputer 150 to control the LED of the phototriac coupler 162 to turn on / off the commercial power supply. The output waveform of the phototriac coupler 162 at the position (B) in FIG. 33 is as shown in FIG. 34B. For example, 70% of the first half of the sine wave 163 of the commercial power supply is off and only 30% of the second half is off. The intermittent waveform 164 is controlled by the microcomputer 150 so as to be turned on. The waveform at the position (C) in FIG. 33 after the rectifier circuit 159 is a one-way waveform 165 obtained by folding the AC waveform in only one direction as shown in FIG. 34 (C), and the position at (D) in FIG. The waveform at is an applied waveform 166 with reduced pulsation as shown in FIG. 34 (D), and is applied to the coil of the stator 92.

  Here, by changing the ON / OFF ratio of the phototriac coupler 162 according to the control signal from the microcomputer 150, the ON time ratio can be varied. For example, the maximum time is 100% ON and the minimum time is 30% ON. be able to.

  As described above with reference to FIG. 31, the load of the solenoid 91 is very small from the start of driving, and the maximum load is applied only just before the end of driving. Thus, the preferred drive characteristics of the solenoid 91 will be described with reference to FIG. 35. The horizontal axis represents the drive time of the solenoid 91, and the vertical axis represents the power applied to the coil of the stator 92 of the solenoid 91. As an example, the power e2 is 100% at the maximum, and the power e1 is 30% at the minimum.

  For example, when e1 of low power is applied to the solenoid 91 for about 1 second from the start of driving of the solenoid 91 to the time t1, the load is slight and the plunger 93 moves to the position P2 in FIG. At this time, in FIG. 15 to FIG. 16, the tip of the drive lever 45 moves to the inside of the heating chamber 2 and moves until it contacts the release lever 62. Material 135 or dry yeast 133 cannot be dropped. Since this operation is low in power, the impact sound and impact force when the drive lever 56 collides with the release lever 62 are small, noise can be reduced and the occurrence of impact stress can be prevented to achieve high reliability.

  When e2 of the maximum power is applied to the solenoid 91 after the elapse of a predetermined t1 time, the driving force of the solenoid 91 is set to be larger than the maximum load F4 (see FIG. 31). The yeast 133 or the ingredients 135 can be put into the bread baking container 28 by being fully pushed. Since the tip of the drive lever 45 is already in contact with the release lever 62 when the maximum power e2 is applied, even if the maximum power e2 is applied to the solenoid 91, the operation amount of the drive lever 45 and the plunger 93 is small. In addition, it is low speed and can reduce the impact sound and impact force.

  When the energization is stopped after the elapse of a predetermined time, for example, 1 second after the e2 of the maximum power is applied to the solenoid 91, and the energization is stopped, the plunger 93 is driven by the spring 100 force and the weight of the push rod 73 as shown in FIG. ) (B) to return to the position shown in FIG. The energization may be cut off at time t2, or may be cut off after applying low power e1 until a predetermined time t3.

  Further, by providing the smoothing circuit 160, while the power is continuously applied after the plunger 93 is sucked, the suction force periodically fluctuates due to the pulsation after rectification, and the plunger 93 vibrates to 50 Hz or all generated. There is an effect of reducing vibration of 100 Hz after wave rectification, so-called electromagnetic sound.

In the present embodiment, the case where the maximum load is applied only when the driving of the solenoids 91 and 101 is completed is described. However, the present invention is not limited to such a load characteristic. Even when 101 is used, there is an effect of reducing impact sound and impact force.
