In this description, the “readable bread maker” means that the bread maker is placed on a horizontal surface, and each part such as a lid and a bread case is set at a predetermined position. It is a concept that includes both a bread maker that can make bread and a bread maker that is making bread.

  As shown in FIGS. 3 and 4, the main body 10 includes an outer case 11 and an inner case 12. The bread maker 1 further includes a bread case 30 that serves as a baking mold for bread. 3 is a cross-sectional view taken along line AA in FIG.

  The outer case 11 is a resin molded product having a bottomed substantially cylindrical shape with an upper surface opened and a lower surface closed, and is formed in a substantially rectangular shape in plan view. The outer case 11 constitutes an outer wall and a bottom wall of the bread maker 1, and accommodates the inner case 12, the control device (the microcomputer 70), the stirring mechanism 80, and the like on the inner side. From the opening formed in the upper part of the outer case 11, the pan case 30 can be taken in and out.

The inner case 12 forms a substantially concave space inside the outer case 11 by a plurality of members, and is attached to the inner side of the outer case 11. The inner case 12 constitutes the inner wall of the bread maker 1.
The inner case 12 is constituted by a lower case 12A constituting the lower part and an upper case 12B constituting the upper part, and a concave space formed by the lower case 12A and the upper case 12B is used as a baking space for bread.

  A plurality of ribs 12C that are multi-staged in the vertical direction are formed on the outer peripheral side surface of the lower case 12A. By wiring one line at a time between the adjacent ribs 12C and 12C, the work coil 13 is It is composed. In the bread maker 1, a work coil 13 for induction heating is disposed on the outer periphery of the lower case 12A.

  The work coil 13 heats the bread case 30 to ferment bread dough or to bake bread. The work coil 13 is supported on the outer surface of the lower case 12A.

  In the present embodiment, the heating means of the bread case 30 in the bread maker 1 is an IH (Induction Heating) method, but the heating method of the bread case 30 in the bread maker 1 is limited to the IH method. is not. That is, in the bread maker 1, the heating means of the pan case 30 may be an electric heater or the like, and the pan case 30 may be externally heated.

The rear end portion of the lid body 20 is supported via a hinge attached to the upper end rear edge portion of the outer case 11. The lid 20 is configured to be openable and closable with respect to the main body 10.

  The bread case 30 is a container whose upper surface is open and whose lower surface is closed, and allows bread dough (bread ingredients) to be accommodated therein. It is configured to be detachable from the inner case 12 via a coupling member (not shown) attached to the lower surface.

  In the bread maker 1, a space surrounded by the inner case 12 and the inner surface 21 of the lid 20 is a bread baking space, and a bread bulging space PA is secured as a baking space above the bread case 30. ing.

  Further, the bread maker 1 includes a top surface heating unit 40 that heats the top surface of the bread above the bread bulging space PA. The term “bread top” as used herein refers to the top surface of the bread that has been baked and is generally in the shape after baking.

The top surface heating unit 40 is means for coloring the top surface of the bread, and includes a heater 41, a heat reflecting member 42, and a support member 43.
The heater 41 is an electric heater, and various types of electric heaters such as a seed type and a mica type can be adopted. The heater 41 has a substantially flat heat generating portion for uniformly coloring the top surface of the bread, and the heat generating portion is configured by arranging a plurality of rod-shaped heater members on a flat surface, for example. The

  The heat reflecting member 42 is a member for reflecting the heat radiated from the heater 41 toward the top of the pan. The heat reflecting member 42 is a member in which a heat reflecting surface having a predetermined reflection angle is formed by pressing or bending a plate material made of glossy aluminum or the like on the surface. The support member 43 is a member for supporting the heater 41.

  The top surface heating unit 40 in the bread maker 1 is configured by attaching a heat reflecting member 42 to the inner surface 21 of the lid 20 and further attaching a support member 43 to the heat reflecting member 42. The top surface heating unit 40 supports the heater 41 with the support member 43, thereby arranging the heater 41 on the inner surface 21 of the lid 20.

  As shown in FIG. 5, in the bread maker 1, the top surface heating unit 40 is arranged above the bread bulging space PA, not around the side of the bread bulging space PA above the bread case 30. The bread bulging space PA is a baking space between the lid 20 and the bread case 30 and is a space secured for extending the bread P heated and baked in the bread case 30 upward.

  In the bread maker 1, the top surface heating unit 40 is disposed on the inner surface 21 of the lid body 20 located above the bread bulging space PA, so that the heat from the heater 41 toward the pan case 30 is substantially downward. Is configured to emit. That is, the top surface heating unit 40 is disposed on the inner surface 21 of the lid 20 so that heat can be radiated in a direction substantially perpendicular to the upper open end surface of the pan case 30 in the inner case 12. It is configured.

In the bread maker 1 having such a configuration, the heater 41 can radiate heat from the direction substantially orthogonal to the top surface PU of the bread P in the bread bulging space PA above the bread case 30, An appropriate baking color can be applied to the top surface PU of the bread P without scorching the shoulder or side of the bread P.
As shown in FIG. 5, the top surface PU of the pan P usually has a substantially arcuate shape. Therefore, the “direction substantially orthogonal to the top surface PU” referred to here is the top surface PU. The concept includes not only the normal direction to the surface PU but also a direction slightly inclined (for example, about 30 °) from the normal direction.

  In the bread maker 1, the bread P heated by the work coil 13 and bulging upward from the bread case 30 is heated by the top surface heating unit 40, so that the top surface PU of the bread P is surely given a good baked color. Can be attached.

  That is, in the bread maker 1, the radiation direction of the heat by the heater 41 of the top surface heating unit 40 with respect to the top surface PU of the pan P is substantially orthogonal to the top surface PU of the pan P. The bread device 1 makes it possible to surely color the top surface PU of the bread P. In the configuration in which the heating means is arranged around the side of the bread bulge space as in a conventional bread maker, if you try to give a good baking color to the top surface of the bread, you first put it on the shoulder or side of the bread There was also a problem that the baked color was attached and the shoulder and side portions were burnt, but the bread maker 1 is good for the top surface PU of the bread P without scorching the shoulder and side portions of the bread (appropriate ) Can be baked.

Further, the bread maker 1 includes a heat reflecting member 42 that reflects heat on the inner surface 21 of the lid 20. That is, the heat reflecting member 42 is disposed in the bread bulging space PA.
The heat reflecting member 42 can repeatedly reflect the heat radiated from the top surface heating unit 40 toward the top surface PU of the pan P and the heat radiated from the support member 43 toward the top surface PU. For this reason, in the bread maker 1, the heat radiated from the heater 41 can be efficiently used to color the top surface PU of the bread P by the heat reflecting member 42.

  That is, the bread maker 1 includes a heat reflecting member 42 that reflects heat on the inner surface 21 of the lid 20 (that is, above the bread bulging space PA). This makes it possible to efficiently tint the top surface PU.

  And in the bread maker 1, as shown in FIG.3 and FIG.4, the material input device 50 and the yeast input device 60 are provided in the rear part of the cover body 20. As shown in FIG. In the bread maker 1, a space for placing the top heating portion 40 on the inner surface 21 of the lid 20 by arranging the ingredient thrower 50 and the yeast thrower 60 close to the rear side of the lid 20. Is secured.

The ingredient thrower 50 is for throwing ingredients (food ingredients such as raisins and nuts) into the bread dough in the bread case 30 at a predetermined timing, and is disposed on the inner surface 21 of the lid 20.
And in the bread maker 1 in the state which can be used, the ingredient | tool throwing device 50 is set as the structure provided with the door part 51 which can be opened diagonally downward toward the upper end opening part of the bread case 30, and was stored inside. The material is configured to drop downward by its own weight when the door portion 51 is opened.

The yeast thrower 60 is for throwing dry yeast into the bread dough in the bread case 30 at a predetermined timing, and is disposed on the inner surface 21 of the lid 20.
The yeast thrower 60 is configured to include a door 61 that can be opened obliquely downward toward the upper end opening of the bread case 30 in the bread maker 1 in a usable state. The yeast is configured to drop downward by its own weight by opening the door portion 61.

The stirring mechanism 80 is a mechanism for kneading the dough, and includes a motor 81, a small pulley 82, a large pulley 83, a V belt 84, a rotating shaft 85, a bearing 86, a stirring blade 87, and the like.
In the stirring mechanism 80, a small pulley 82 is fixed on the main shaft 81 </ b> A of the motor 81, and a V belt 84 is wound between the small pulley 82 and the large pulley 83. The rotary shaft 85 is rotatably supported by a bearing 86.
The large pulley 83 is fixed to the rotation shaft 85, and the rotation output of the motor 81 is transmitted to the large pulley 83 via the small pulley 82 and the V belt 84, so that the rotation shaft 85 is driven to rotate. Is done. The upper end portion of the rotation shaft 85 is located inside the pan case 30.
The stirring mechanism 80 has a stirring blade 87 fixed to the upper end portion of the rotating shaft 85, and rotates the stirring blade 87 by the operation of the motor 81 to knead the bread dough (not shown) in the bread case 30. It is configured to be able to.

  That is, the bread maker 1 includes a main body 10 and a lid 20 that form a space for baking bread P, a bread case 30 that is a baking mold of bread that can be accommodated in a space formed by the main body 10 and the lid 20, A work coil 13 that heats the bread dough in the bread case 30 to bake the bread, and a top surface heating unit 40 that heats the top surface PU of the bread P baked by the work coil 13. Is provided on the inner surface 21 of the lid 20. According to the bread maker 1 having such a configuration, it is possible to bake bread P (see FIG. 5) having a good baking color on the top surface PU.

In addition, when the heating means of the pan case 30 in the bread maker 1 is an induction heating type heater (work coil 13), the pan coil 30 is self-heated by the work coil 13 so that the bread is baked. The local heat that is done contributes little to coloring the top of the bread. For this reason, when the heating means of the bread case 30 in the bread maker 1 is an induction heating type, the baking color of the top surface of the bread tends to be thinner.
As in the bread maker 1 shown in the present embodiment, when the heating means of the bread case 30 is an induction heating type, in order to bake bread with a good baking color on the top surface, the upper part of the bread case 30 It is particularly effective to provide a configuration in which the top surface heating unit 40 is provided.

  That is, in the bread maker 1, the bread baking means is the work coil 13, and the work coil 13 induction heats the pan case 30. According to the bread maker 1 having such a configuration, even when the induction heating type work coil 13 is employed, it is possible to bake bread P having a good baking color on the top surface PU (see FIG. 5). .

Here, another embodiment of the bread maker will be described.
The bread maker 2 shown in FIG. 6 is an embodiment of the bread maker according to the present invention.
As shown in FIG. 6, the bread maker 2 is configured to use a bread case 35 for baking square bread, and includes a top surface heating unit 45. Since other configurations are the same as the configuration of the bread maker 1 described above, the description thereof is omitted.

The pan case 35 is used together with the pan case lid member 36 that seals the open end surface of the upper portion of the pan case 35, and the square bread is baked inside the substantially rectangular parallelepiped sealed space.
In the bread maker 2 using the bread case 35, the bread dough in the bread case 35 is baked by the work coil 13, and the bread case cover member 36 is heated by the top surface heating unit 45 to be baked on the top surface of the square bread. Add color. As the heater 46 constituting the top surface heating unit 45, an external heating type electric heater may be employed, or an induction heating type heater may be employed.

Next, operation control of the bread maker 1 will be described with reference to FIGS. 3 and 4.
The bread maker 1 includes a microcomputer 70 as control means. The microcomputer 70 stores in advance a control program for executing the functions of the bread maker 1, a relationship map between time and temperature, and the like. The microcomputer 70 receives various signals from various sensors (not shown) that detect the state of the bread dough, the temperature inside the cabinet, etc., and performs calculation and determination based on the signals. By outputting a control signal to the top surface heating unit 40 or the like, each part of the bread maker 1 is appropriately operated.

Next, the operation of the bread maker 1 will be described with reference to FIGS. 3 to 5 as appropriate.
The bread maker 1 bakes bread by sequentially performing a kneading process, a primary fermentation process, a secondary fermentation process, and a baking process.

  In the kneading process, the bread maker 1 operates the work coil 13 so that the temperature in the bread case 30 can maintain the temperature set in the kneading process.

  In the kneading process, the bread maker 1 agitates materials such as water, wheat flour (strong flour), salt, fats and oils that are the basis of the bread dough with the stirring mechanism 80 and kneads the bread dough.

  In the kneading process, the bread maker 1 throws dry yeast into the dough when the dough has been kneaded to some extent. That is, the microcomputer 70 throws dry yeast into the bread dough from the yeast thrower 60 when the dough kneading progresses to some extent. Thereafter, the microcomputer 70 further kneads the bread dough for a predetermined time for spreading the dry yeast uniformly throughout the dough, and completes the kneading process.

  After the kneading process is completed, the bread maker 1 may further add ingredients (for example, raisins and nuts) to the bread dough. In this case, in the bread maker 1, the ingredients are introduced by the ingredient feeder 50 before the primary fermentation step. Here, the microcomputer 70 kneads the bread dough further lightly by the stirring mechanism 80 to such an extent that the ingredients are not crushed so that the ingredients spread all over the bread dough.

Next, the bread maker 1 performs a primary fermentation process.
In the primary fermentation process, the bread maker 1 operates the work coil 13 so that the temperature in the cabinet can be maintained at the temperature set in the primary fermentation process by the microcomputer 70.

After the primary fermentation process is completed, the bread maker 1 performs the secondary fermentation process.
In the secondary fermentation process, the bread maker 1 operates the work coil 13 so that the microcomputer 70 can maintain the temperature set in the secondary fermentation process by the microcomputer 70.
By performing such a primary fermentation process and a secondary fermentation process, the bread maker 1 molds and ages bread dough.

After the secondary fermentation process is completed, the bread maker 1 performs the baking process.
In the baking process, the bread maker 1 operates the work coil 13 so that the internal temperature can be maintained at the temperature set in the baking process by the microcomputer 70, and the work coil 13 bakes the bread dough.

  In the baking process, the bread maker 1 bakes the dough by the work coil 13 and the dough bulges into the bread bulging space PA above the bread case 30 (that is, a predetermined time has elapsed). Later, the microcomputer 70 further operates the heater 41 of the top surface heating unit 40 in order to color the top surface PU of the pan P.

  By performing such a baking process, the bread maker 1 can bake bread P with a good baking color on the top surface PU. Moreover, in the bread maker 1, the operation time of the heater 41 is shortened by limiting the heating by the top surface heating unit 40 after the bread P bulges in the bread bulging space PA, and the bread maker 1 Power consumption is suppressed. Further, if the heater 41 is operated before the pan P bulges into the bread bulge space PA, the distance between the heater 41 and the top surface PU is long, and it is difficult to efficiently color the top surface PU. By limiting the heating by the top surface heating unit 40 after the bread P has bulged into the bread bulging space PA, the top surface PU of the bread P can be colored efficiently.

  That is, in the bread maker 1, the top surface heating unit 40 starts heating after a predetermined time has elapsed since the baking of the bread by the work coil 13 is started. Therefore, the top surface PU of the bread P can be surely colored with less power consumption.

  In the bread maker 1 shown in the present embodiment, the heater 41 is operated after the bread P bulges into the bread bulging space PA. However, in the bread maker 1, the power consumption is smaller. It is also possible to operate the heater 41 prior to the timing when the bread P bulges into the bread bulging space PA, giving priority to the preference of the baked color. In the bread maker 1 in this case, it is possible to shorten the baking time of the bread P by advancing the operation timing of the heater 41 or to add a solid baking color to the top surface PU of the bread P. become.
