  However, the conventional cooking device has the following problems.

  When making powder such as wheat flour (strong flour) or yeast in the input case, and making the input case directly above the heated bread case, the temperature of the powder in the input case rises. There was a risk that the flour would harden or the yeast would die and no longer ferment.

  As shown in Patent Document 2, the bottom wall of the charging case is composed of a rotatable lower lid, and when the lower lid is opened, the powder in the charging case is charged into the pan case. However, due to the opening operation of the lower lid, there is a problem that the lower lid flutters and the powder is scattered around the bread case due to the opening moment when the lower lid is fully opened.

  The side wall of the charging case is formed in a taper shape that extends upward from below so that powder can be easily put from above. However, when the lower lid is opened, the powder remains attached to the side wall of the charging case, and there is a complaint that the powder cannot be reliably charged into the pan case.

  Yeast bacteria, which are powders placed in the charging case, are killed when the temperature is 60 ° C. or higher. Therefore, the temperature of the charging case must be 60 ° C. or lower. In addition, when the charging case becomes hot, there is a problem that the flour, which is a powder, is hardened. In particular, it faces the baking chamber that houses the pan case, and the openable and closable lower lid that constitutes the bottom wall of the charging case becomes hot, and the powder that contacts the lower lid tends to be hot.

  In order to indicate to the user the amount of powder to be set in the input case, it is necessary to indicate some reference mark by, for example, printing. However, adding such a process itself has a problem of increasing costs.

  When the charging case is composed of a case main body having a hollow part with a gap formed at one end and a packing attached to the gap of the case main body, if the liquid enters the hollow part from the gap, the liquid is put outside the charging case. Can no longer be discharged, causing problems in hygiene.

  When a transparent member is provided so that the inside of the charging case can be visually confirmed, when the rising heat from the charging case reaches the transparent member, there is a problem that the temperature of the member attached with the transparent member increases.

Then, when the upper lid opening / closing lever 37 is pushed, the main body lid 34 and the upper lid 35 are disengaged, and the upper lid 35 can be opened with respect to the main body lid 34 by lifting the front side of the upper lid 35 from this state. Become. FIG. 8 shows a state in which the upper lid 35 is opened.

  An opening / closing knob 38 projecting outward is provided on both front sides of the main body lid 34. By holding the opening / closing knob 38 in a state where the upper lid 35 is engaged with the main body lid 34, the main body lid 34 is provided. The entire lid 31 including 34 and the upper lid 35 can be opened and closed. FIG. 9 shows a state in which the entire lid 31 is opened.

  The lid 31 is provided with a charging case 41 for charging powder such as yeast or flour into the bread case 7 during cooking. The input case 41 is mounted on a hollow case attachment portion 42 provided on the main body lid 34 and located immediately above the pan case 7, and can be attached and detached from the upper surface side of the main body lid 34 with the upper lid 35 opened. It has become. In addition, when the upper lid 35 is closed, the upper lid 35 is opposed to the upper surface of the charging case 41 so that the powder in the charging case 41 can be seen from the upper surface side of the opening of the charging case 41 attached to the main body lid 34. A glass window 44 which is a plate-like transparent member is disposed. The glass window 44 is closely fixed to the upper lid 35 with a packing 45 made of an elastic body such as rubber interposed therebetween.

  As shown in FIG. 10, the main body lid 34 is fixedly attached to the lower side of the charging case base 47 that forms the skeleton of the main body lid 34, and the upper surface of the storage chamber 6 when the lid 31 is closed. The outer cover 48 and the steam port cover 49 covering the upper surface of the charging case base 47 constitute an outer shell. In addition, a cylindrical steam port unit 51 that forms a steam passage 50 to be described later is disposed behind the main body lid 34. One end of the steam port unit 51 is attached and fixed to the steam intake hole 53 of the charging case base 47 via a packing 52 made of an elastic body such as rubber, and the other end of the steam port unit 51 is provided on the steam port cover 49. The steam port 54 is provided. Further, the steam intake hole 53 of the charging case base 47 communicates with an opening 55 formed behind the inner lid 48. As described above, the case attachment portion 42 that is opened is provided in the approximate center of the main body lid 34, but the case does not enter the main body lid 34 from the gap between the charging case 41 and the main body lid 34. Another packing 56 that is in close contact with the charging case 41 is disposed on the side wall of the mounting portion 42.

  As shown in FIG. 11, the upper lid 35 includes an upper lid base 58 that forms a skeleton of the upper lid 35 and an upper lid cover 59 that covers the upper surface of the upper lid base 58. Here, the upper lid cover 59 that forms the outer surface of the cooker is formed of a resin material that is inferior in heat resistance to the upper lid base 58, so that the temperature rise of the glass window 44 facing the charging case 41 is applied to the upper lid base 58. In order not to reach, the glass window 44 is sandwiched between an upper lid base 58 and an upper lid cover 59 arranged with a space 60 therebetween, with the periphery held by the packing 45.

  In addition, a printing portion 61 is formed on the periphery of the upper surface of the glass window 44 located in the vicinity of the boundary portion of the upper lid 35 to blind the contents inside the lid 31. Although the printing part 61 forms a slight convex part on the surface of the flat glass window 44, what should be noted here is that the printing part 61 is provided on the upper surface, not on the lower surface of the glass window 44. That is, if the printing unit 61 is formed on the lower surface of the glass window 44 facing the input case 41, the printing unit 61 may be peeled off together with the powder adhered to the lower surface of the glass window 44. In this regard, the upper surface of the glass window 44 is hard to adhere the powder from the charging case 41, and if the printing unit 61 is provided only there, the possibility of peeling the printing unit 61 can be avoided.

  Next, the configuration of the charging case 41 shown in FIG. 12 will be described. The input case 41 includes a case main body 71 having an upper surface and a lower surface opened, and an opening / closing plate 72 that closes the lower surface opening of the case main body 71. The opening / closing plate 72 that forms the bottom wall of the charging case 41 has a double plate structure in which a first lower lid 73 and a second lower lid 74 are arranged side by side. A cooling air passage 75 is formed as an air layer through which the wind from the cooling fan 26 passes. In addition, one side of the first lower lid 73 and the second lower lid 74 is attached to one side lower portion of the case body 71 with a hinge shaft 76, and the lower surface opening of the case body 71 is centered on the hinge shaft 76. It is the structure which can be rotated so that opening and closing is possible. Here, the hinge shaft 76 of the first lower lid 73 and the second lower lid 74 is shared, thereby reducing the number of parts and reducing the cost.

  In the present embodiment, in order to avoid a thermal effect when the temperature of the storage chamber 6 and thus the lid 31 rises due to energization of the heating means 8, the cooling fan is attached to the main body 1 instead of the lid 31 covering the upper surface opening of the main body 1. 26 is provided. As shown in FIGS. 7 and 9, an air passage opening 78 connected to the discharge port of the cooling fan 26 is provided in the upper portion of the main body 1 in order to guide the air from the cooling fan 26 to the cooling air passage 75. At the same time, an air guide port 79 is provided on the side surface of the inner lid 48 so as to face the air passage opening 78, and the space between the input case base 47 and the inner cover 48 is used to make the case of the air guide port 79 and the main body lid 34. The cooling air passage 75 of the charging case 41 attached to the attachment portion 42 is communicated. Further, the cooling air passage 75 communicates with the steam passage 50 via the steam intake hole 53 of the charging case base 47, whereby the air from the cooling fan 26 is taken into the air inlet 79 through the air passage opening 78. After being guided to the cooling air passage 75, the cooling air passage 75 is discharged to the outside of the cooker through the steam passage 50 which is a steam exhaust passage.

  As described above, the base end side of the opening / closing plate 72 is attached to one side lower part of the case body 71 by the hinge shaft 76, but the distal end side of the opening / closing plate 72 is locked by the movable portion 81 provided in the case body 71, The lower surface opening of the case body 71 is sealed by the opening / closing plate 72 by pressing the packing 82 made of an elastic material such as rubber provided on the periphery of the lower surface opening of the case body 71 on the upper surface of the opening / closing plate 72.

  In the present embodiment, a solenoid 63 (see FIG. 22) is disposed inside the main body 1 as a configuration in which the movable portion 81 of the input case 41 is movable with the lid 31 closed. The solenoid 63 serves as a drive source for switching the open / close plate 72 from the closed state to the open state. When the solenoid is energized in response to a drive signal from the control unit 30 during cooking, the movable unit 81 is pushed. Thus, the locking between the movable portion 81 and the opening / closing plate 72 is released, and the opening / closing plate 72 is opened around the hinge shaft 76 by its own weight. In addition, by the opening operation of the opening / closing plate 72, when the opening / closing plate 72 is opened, the braking force is applied to the opening / closing plate 72 so that the opening / closing plate 72 does not flutter with the opening force when the opening / closing plate 72 is completely opened. A brake spring 83 to be generated is disposed on the hinge shaft 76. As a result, the powder in the charging case 41 passes through the lower opening of the openable opening and closing plate 72 and does not scatter around the pan case 7 and is dropped into the pan case 7 positioned immediately below.

  The second lower lid 74 is detachably attached to the first lower lid 73 by a fixing member 84. The fixing member 84 is configured by using one of the first lower lid 73 and the second lower lid 74 as a locking portion and the other as a locked portion, and the first lower lid 73 in the state of the input case 41 alone. Only the second lower lid 74 can be opened from the first lower lid 73 while being locked to the movable portion 81. Thereby, the cooling air path 75 between the first lower lid 73 and the second lower lid 74 can be easily cleaned.

  The case main body 71 is configured by providing a heat insulating space 87 between a case portion 85 that is a member for storing powder and an outer surface portion 86 that is a member forming the outer surface of the charging case 41. Further, a lower end which is one end of the case main body 71 is formed with a gap 88 which communicates the heat insulating space 87 and the outside of the case main body 71. The heat insulating space 87 and the gap 88 are formed on the entire outer periphery of the side wall 89 so as to surround the side wall 89 of the case body 71 that defines the storage area of the powder 71. Thus, by providing the heat insulating space 87 in the charging case 41, it is possible to suppress the temperature rise of the powder in the charging case 41.

  In the present embodiment, the angle of the side wall 89 with respect to the bottom wall of the charging case 41 is formed larger than the vertical. That is, the side wall 89 of the charging case 41 is formed in a reverse taper shape that extends downward from above. Although not shown here, the angle of the side wall 89 with respect to the bottom wall of the charging case 41 may be formed perpendicularly. In any case, if the angle of the side wall 89 is defined in this way, when the opening and closing plate 72 is opened, the powder falls from the side wall 89 of the charging case 41 without adhering to the opening and closing plate 72, and the brake spring 83 causes the opening and closing plate 72 to move. In combination with the application of the braking force, the powder can be reliably charged into the pan case 7 from the charging case 41.

  5 and 6, the air flow F during cooking is indicated by arrows. As shown in FIG. 5, until the powder is charged into the pan case 7 from the charging case 41, the control unit 30 operates the cooling fan 26 so that the air discharged from the cooling fan 26 is The air enters the air guide port 79 of the inner lid 48 from the air passage opening 78 and passes through the cooling air passage 75 formed at the bottom of the charging case 41. Thereby, even if the bread raw material in the bread case 7 is heated by the heating means 8 and the temperature of the storage chamber 6 and the lid 31 rises thereby, the cooling air passage 75 through which the air from the cooling fan 26 flows is forced, It is possible to avoid the thermal influence on the powder stored in the charging case 41 as much as possible.

  In addition, steam is generated from the bread case 7 into the storage chamber 6 as the bread material in the bread case 7 is heated, and the steam enters the steam passage 50 from the opening 55 formed in the inner lid 48. And mixed with the wind from the cooling fan 26 that has passed through the cooling air passage 75. Therefore, the steam can be safely discharged from the main body 1 to the outside of the cooking device while lowering the temperature of the steam passing through the steam passage 50.

  On the other hand, as shown in FIG. 6, after the powder is charged from the charging case 41 to the pan case 7, the open / close plate 72 of the charging case 41 is opened. In this case, the steam generated in the storage chamber 6 from the pan case 7 passes through the steam passage 50 not only from the air inlet 79 of the inner lid 48 described above, but also from the cooling air passage 75 and the bottom of the open case 41. And discharged outside the cooker. Further, by sending wind from the cooling fan 26 toward the steam passage 50, the temperature of the steam passing through the steam passage 50 can be lowered.

  Next, based on FIGS. 13-17, the detailed structure of the input case 41 mentioned above is demonstrated.

  As shown in FIG. 13, the packing 82 protrudes outward from the attachment portion 91 attached to the gap 88 of the case main body 71 and the gap 88 of the case main body 71, and is attached to the opening / closing plate 72 when the opening / closing plate 72 is closed. It is comprised by the ear | edge part 92 pressed. Further, the case portion 85 is formed with a protruding parting line 93 formed on the side wall 89 when the case portion 85 is formed by a mold (not shown) that is divided vertically. The parting line 93 is provided at a position that serves as a guideline for the amount of powder set in the charging case 41. This makes it possible to show the guideline for the amount of powder to the user without increasing the number of steps. .

  FIG. 14 shows a cross section in a state in which the lower end of the charging case 41 faces upward. In this figure, here, the heat insulation space is located at a position higher than the height H of the packing 82 entering the heat insulation space 87 as a hollow portion (the height of the upper end of the mounting portion 91) and higher than the height H. A plurality of drainage holes 94 are provided to communicate between the 87 and the outside of the charging case 41. The drain hole 94 is provided in the outer surface 86 of the case body 71, but may be provided in the case 85. With such a drain hole 94, when the charging case 41 is oriented in the original direction, the liquid that has entered the heat insulating space 87 from the gap 88 does not stay in the heat insulating space 87 and is discharged from the liquid drain hole 94. It is discharged outside the case 41.

  FIG. 15 shows the configuration around the movable portion 81 described above with the lower end of the input case 41 facing upward. In addition to the solenoid operating body 95 that is pushed by a solenoid (not shown), the movable portion 81 is provided with a slidable hook portion 96 that allows the user to manually open the opening / closing plate 72. The hook portion 96 is small and is disposed at a position where the hand can be touched. However, the hook portion 96 is provided at a position where the sliding operation can be performed only from the lower side of the input case 41, and the structure is such that the hand is not easily touched during normal times. In other words, by providing the hook portion 96, the opening and closing plate 72 can be opened and closed using the hook portion 96 when cleaning the charging case 41, but at the normal time, the hook portion 96 is in a position where it can only be operated from below. Since it is not easily touched, it can prevent the powder from falling due to misuse.

  FIG. 16 shows that the seal between the case main body 71 and the packing 82 is used as a seal portion at a position close to the powder stored in the charging case 41, that is, a position near the open end of the gap 88. A protrusion 97 is provided. The protrusion 97 here is formed integrally with the packing 82, but instead, an adhesive separate from the packing 82 such as RTV (Room Temperature Vulcanizing) rubber is used as the sealing portion. It doesn't matter. Thereby, the protrusion 97 can effectively prevent the liquid from leaking between the case main body 71 and the packing 82, and the sealing performance between the case main body 71 and the packing 82 can be improved.

  FIG. 17 shows the positional relationship between the packing 82 and the first lower lid 73 of the opening / closing plate 72 provided to be rotatable about a hinge shaft 76 that is a hinge portion. In the same figure, S shows the locus | trajectory accompanying opening and closing of the opening-and-closing board 72. FIG. Here, a rib 98 is formed at the lower end of the case body 71 in order to prevent deformation of the ear portion 92 of the packing 82. The rib 98 is deformed until the ear portion 92 enters the side wall 89 when the opening / closing plate 72 is closed and the packing 82 is pressed against the opening / closing plate 72, and the sealing between the opening / closing plate 72 and the packing 82 is insufficient. It is provided in order to prevent the occurrence of the part. That is, if the rib 98 shown in FIG. 17 is provided, when the opening / closing plate 72 is closed and the packing 82 is pressed against the opening / closing plate 72, the ear portion 92 abuts against the rib 98 to prevent further deformation, The gap between the opening / closing plate 72 and the packing 82 can be reliably sealed. The deformation of the ear portion 92 becomes prominent particularly in a portion that is strongly pressed against the opening / closing plate 72 in the vicinity of the hinge shaft 76. Therefore, a rib 98 is provided on at least one side of the case body 71 located on the hinge shaft 76 side. If provided, such a lack of sealing between the opening / closing plate 72 and the packing 82 can be surely solved.

  FIG. 18 is a diagram illustrating a detailed configuration of the lid 31 including the input case 41. As described above, the main body lid 34 and the upper lid 35 constituting the lid 31 are fitted by the fitting portion 99 including the upper lid opening / closing lever 37 and are rotated together around the shaft 32. FIG. 18 shows a state in which the body lid 34 and the upper lid 35 are fitted by the fitting portion 99 and the lid 31 is opened from the opening of the body 1.

  Here, if the fitting force between the main body lid 34 and the upper lid 35 is smaller than the force required to open the opening / closing plate 72 which is the lower lid of the input case 41, the user moves the opening / closing plate 72 in the state of FIG. When opened, the upper lid 35 is detached from the main body lid 34 and opened, which may cause the main body 1 to fall. Therefore, in the present embodiment, the fitting force between the main body lid 34 and the upper lid 35 is set larger than the force for opening the opening / closing plate 72, so that when the user opens the opening / closing plate 72, the upper lid 35 is removed from the main body lid 34. Can be prevented from being opened and the main body 1 can be prevented from being overturned.

  FIG. 19 is a diagram illustrating a detailed configuration of the main body 1 described above. In the figure, reference numeral 101 denotes a concave code box provided on the back surface of the main body 1, which is provided with a flexible power cord 102 for supplying power to each part of a cooking device such as the control unit 30. It is done. Reference numeral 103 denotes a battery case provided inside the code box 101. The battery case 103 is provided with a holding part 105 for holding a flat button battery 104 in a detachable manner. Reference numeral 106 denotes a cord box cover that covers the opening of the cord box 101 so that the cord box 101 can be opened and closed. Regardless of whether the cord box cover 106 is opened or closed, the battery case 103 is exposed from the cord box 101 and the battery case 103 holds the button. The button battery 104 can be replaced by taking out the part 105. The button battery 104 as a primary battery supplies the minimum necessary power to the cooker even when power supply to the cooker by the power cord 102 is interrupted. Used for setting memory retention function.

  In this case, the cord box 101 for storing the power cord 102 is disposed in the main body 1, and the battery case 103 for storing the button battery 104 is provided in the cord box 101. There is no need to provide a separate part, and an inexpensive and simple structure can be realized.

  As for the detailed configuration of the input case 41, the lid 31, and the main body 1, only one or a plurality of them may be adopted, or all of them may be adopted. Moreover, you may apply to the modification mentioned later.

  20 and 21 show another modification example regarding the mounting position of the input case 41. In FIG. 20, a bread case 7 (not shown) is accommodated in a storage chamber 6 that is a storage container having an open top surface, and a charging case 41 is disposed in the lid 31 so as not to face the top surface of the storage chamber 6. Yes. In this case, in order to guide the powder from the charging case 41 to the bread case 7, an inclined introduction pipe 111 is provided in the cooking device, and an opening / closing lid 112 that opens and closes the lower end opening of the introduction pipe 111 is provided. . The opening / closing lid 112 may be opened / closed by the weight of the powder, or may be opened / closed by an electric drive signal by providing an opening / closing means.

  In this way, by placing the charging case 41 on the side of the upper surface of the storage chamber 6 while avoiding directly above the storage chamber 6 serving as a heat source, an increase in the powder temperature in the charging case 41 can be suppressed. Moreover, in this case, it is only necessary to devise the arrangement part of the input case 41, and the simplification of the cooling structure and the cost reduction can be achieved.

  In FIG. 21, the charging case 41 shown in FIG. 20 is installed alone outside the lid 31, not inside the lid 31 that covers the upper surface of the storage chamber 6. Therefore, it is not necessary to provide the input case 41 inside the lid 31, and the structure of the lid can be simplified and made compact. Further, the charging case 41 is not affected by heat from the cooker, and the cooling fan 26 in the main body 1 and the cooling structure of the charging case 41 associated therewith can be eliminated.

  Also here, in order to guide the powder from the charging case 41 to the bread case 7, an inclined introduction pipe 111 is disposed in the cooking device. In addition, 113 is a valve for opening and closing the introduction pipe 111, and 114 is an opening and closing means such as a solenoid connected to the valve 113. When a drive signal is given from the control unit 30 to the opening and closing means 114, the opening and closing means 114 operates. The valve 113 opens the introduction pipe 11, and the powder from the introduction case 41 is introduced into the pan case 7 through the introduction pipe 111. As shown side by side in the figure, the above-described opening / closing lid 112 may be incorporated in place of the valve 113 and the opening / closing means 114. In the modification shown in FIG. 20, the opening / closing lid 112 is replaced by the valve 113 and the opening / closing means 114. You may change to

  Next, a control system related to the cooking device will be described with reference to FIG. In the figure, the control unit 30 has an operating body 3 and temperature sensors 28 and 29 electrically connected to input ports, respectively.

It is configured by suspending an endless transmission belt 148. The structure of the cooker shown in FIGS. 1-21 should just be employ | adopted for a structure other than that suitably.

  Next, the operation of the “cooking” course performed by the bread generation control means 131 will be described in detail with reference to the graph of FIG. In addition, since the operation procedure until selecting the “cooking” course and starting cooking is as described above, the description is omitted.

  In the “Cooking Pan” course, where bread is baked using glutinous rice, rice, yeast, liquids such as water and milk, salt, etc. are used as ingredients, and liquids such as water and milk are added to the rice grains. Specifically, salt and a predetermined amount of water are added to the bread case 7 in addition to the rice grains, and dry yeast and strong flour or fresh powder are placed in the charging case 41 and heated in the first “heating” step. By heating the pan case 7 by means 8, the temperature of the water in the pan case 7 is raised. The liquid such as water to be added to the rice grains is placed in the bread case 7 by 1.3 times or more, preferably 2 times or more of the mass (weight) of the rice grains and 2.3 times as a guide. This is to make the food to be cooked in the bread case 7 into a soft rice shape or a hard rice cake shape in the “heating” step. In the “heating” step, the temperature of the pan case 7 detected by the temperature sensor 28 is managed by the pan generation control unit 131 to adjust the heating amount to the heating unit 8.

  When the start of cooking of the “cooking” course is instructed by operating the start key 3A, the bread generation control means 131 performs a “heating” process of cooking the food to be cooked in the bread case 7. Here, first, the water temperature in the bread case 7 is raised with a temperature of about 60 ° C. or less as a guide, and the rice grains are allowed to absorb water for about 15 to 20 minutes. By promoting the water absorption of rice by the time of cooking, the amount of reducing sugar can be increased to obtain a sweet bread.

  Then, the heating amount with respect to the heating means 8 is increased, and the cooking object in the bread case 7 is heated to a temperature near boiling. During the period from when the rice grains absorb water to the middle of heating to a temperature near boiling, the bread generation control means 131 supplies a drive signal to the motor 21 to rotate the bread blades 14 and the bread case 7 Gently stir the food to be cooked inside. For example, the stirring by the blade 14 can be performed by stirring for 10 seconds at intervals of 5 minutes, or by stirring when the temperature of the pan case 7 reaches a predetermined temperature. Adjustments can be made accordingly. Stirring is performed when the gelatinization of the rice before the inside of the pan case 7 is near the boiling temperature is not sufficiently progressed, and after the inside of the pan case 7 is near the boiling temperature, the stirring is not performed. Yes. By performing such agitation, it is possible to reduce the unevenness of heating of the food to be cooked at the same time while preventing the water in the pan case 7 from scattering.

  In the “heating” step, the bread production control means is such that the water temperature in the pan case 7 is 90 ° C. to the boiling point (100 ° C.) or less, the upper limit temperature is lowered according to the atmospheric pressure conditions, and preferably 96 ° C. to the boiling point or less. 131 controls the temperature by adjusting the heating amount of the heating means 8. In particular, the temperature of the water in the pan case 7 is controlled so that the temperature does not exceed 100 ° C., which is the boiling point.

  In addition, during the “heating” step, the pan generation control unit 131 outputs a pulse drive signal to the fan motor constituting the cooling fan 27 to rotate the fan motor of the cooling fan 27 at a low speed. Thereby, even if the heating means 8 is located above the rice in the bread case 7, rice can be cooked with less heating unevenness and less core by sending wind into the accommodation chamber 6. Note that the rotational speed of the fan motor of the cooling fan 27 can be easily varied according to the duty of the pulse drive signal PWM (pulse width modulated) by the pan generation control means 131.

  Eventually, the water in the pan case 7 runs out and the temperature of the pan case 7 suddenly rises, or whether a predetermined time of 10 to 15 minutes elapses after the temperature sensor 28 detects the vicinity of the boiling temperature, When 50 minutes, which is a predetermined time, have elapsed from the instruction to start cooking, rice cooking heating by the heating means 8 is stopped, the process proceeds from "heating" to "cooling", and unevenness of about 10 minutes, which is the predetermined time, is performed. . These management temperatures and times may be managed at arbitrary temperatures and times according to the actual machine, and are not limited to the specific numerical values shown here.

  In the “cooling” step, in order to quickly cool the rice in the pan case 7, the heating means 8 is not energized and the fan motor of the cooling fan 27 is rotated at the highest speed. As a result, the gelatinized rice grains in the bread case 7 are cooled. In addition, the bread generation control means 131 supplies a drive signal to the motor 21 to rotate the bread blades 14 in order to crush the rice grains in the bread case 7 and generate a state without a core residue. Stir the rice.

  When the food to be cooked in the bread case 7 is lowered to a predetermined management temperature, the “cooling” process is terminated and the process proceeds to the “kneading” process. In the “kneading” step, the bread generation control means 131 continues to supply a drive signal to the motor 21 to rotate the bread blades 14 and knead the rice in the bread case 7. In the bread case 7, the rice grains that have been gelatinized and softened by cooking are soft like rice, and are kneaded with bread blades 14 to be kneaded into bread dough.

  Further, before kneading the rice in the bread case 7 or in the middle of kneading the rice, the bread production control means 131 is a drive signal to the solenoid 63 when the gelatinized rice grains are cooled to 60 ° C. or lower, preferably 40 ° C. or lower. To open the opening / closing plate 72 of the charging case 71. As a result, the yeast and flour put in the charging case 71 are charged into the bread case 7, mixed with the food to be cooked in the bread case 7 and kneaded, and the bread dough is finished in the bread case 7. As the flour to be added, a material containing gluten such as strong flour as a component may be added, or a material not containing gluten such as super fresh flour as a component may be added. Is added after the temperature of the object to be cooked falls to 60 ° C. or lower. In this way, after the rice grains in the bread case 7 are gelatinized in the “heating” step, the starchy material other than the rice grains is added by adding the starchy material other than the rice grains below the gelatinization temperature of the rice grains. Can be kneaded without gelatinization. In addition, when yeast is added at a temperature higher than room temperature such as 40 ° C., the fermentation time is shortened.

  The rotation speed of the motor 21 and the pan blade 14 is delayed from the pan generation control means 131 to the motor 21 so as to be slower after the opening / closing plate 72 of the charging case 71 is opened than before the opening / closing plate 72 of the charging case 71 is opened. A drive signal is supplied to. Thereby, the rotating bread blades 14 can prevent the yeast and flour falling from the charging case 71 to the bread case 7 from being scattered around. Further, after the opening / closing plate 72 of the charging case 71 is opened, the supply of the drive signal to the motor 14 may be stopped for a certain period of time, whereby the operation of the bread blade 14 is constant after the yeast or flour is charged. The time can be stopped to reliably prevent the yeast and flour from scattering. Further, it is possible to manually add the secondary material while the operation of the pan blade 14 is stopped.

  Furthermore, the bread generation control means 131 also applies to the fan motor of the cooling fan 27 in order to prevent the temperature of the bread dough from rising due to heat while the motor 21 is continuously rotated in the “kneading” process. A pulse drive signal is supplied to rotate the fan motor at a low speed.

  The top opening of the bread case 7 is not provided with an inner lid that contacts the bread case 7 and closes the opening. This is because the rice case 41, such as yeast and flour, is used after cooking. This is because it is difficult to drop powder and sub-materials into the bread case 7 if an inner lid is provided when adding sub-materials such as powder or fruit.

  Thus, when the “kneading” process for a predetermined time is completed, the process proceeds to a “fermenting” process for fermenting the yeast mixed in the cooking object. In the “fermentation” step, in order to promote the fermentation of yeast, the heating means 8 is controlled to be cut off based on the temperature of the bread case 7 detected by the temperature sensor 28, and the cooling fan 26 is used to degas. Thus, the operation of sending wind into the storage chamber 6 is repeated. Thereby, during the “fermentation” step, the bread production control means 131 sequentially performs the operations of primary fermentation, secondary fermentation, and shaped fermentation, so that the yeast gradually undergoes fermentation, and carbon dioxide gas is generated to expand the bread dough. .

  When the process shifts to molding fermentation, which is the finishing of the “fermentation” process, the bread production control means 131 manages the temperature detected from the temperature sensor 28 and gradually raises the temperature of the bread dough that is to be cooked to 60 ° C. . In this way, the bread dough bulge can be improved by gently raising the temperature of the bread dough within a temperature range in which the yeast does not die immediately before baking the cooked material. Occurrence can be prevented.

  When the “fermentation” step is completed, the bread production control unit 131 moves to the “baking” step and adjusts the heating amount of the heating unit 8 so that the food to be cooked in the bread case 7 is baked into bread. Also during the “baking” step, the pan generation control means 131 outputs a pulse drive signal to the fan motor that constitutes the cooling fan 27, so that the fan motor of the cooling fan 27 runs at a low speed, as in the above-described “heating” step. Rotate with. As a result, it is possible to send the wind into the storage chamber 6 and heat-circulate it to finish the bread with less uneven baking. When the “baking” step is completed, the process proceeds to the next “warming” step. In order to quickly cool the bread baked in the “baking” step, the cooling fan 27 blows air into the housing chamber 6 in the “warming” step. Send in. Thereby, the bread case 7 and the lid 31 can be cooled as well as the baked bread.

  By the way, glutinous rice is gelatinized at about 60 ° C or higher (β starch is changed to α starch), but when it is eaten as white rice, it can be gelatinized sufficiently to the inside of the rice grain when it is low temperature gelatinized at 98 ° C or lower. Therefore, it becomes so-called core residue rice with a hard part remaining, and is not suitable for the taste. Therefore, holding the temperature of the cooking object at 98 ° C. or higher for 20 minutes is a condition for eating white rice. Therefore, the actual rice cooker has been devised so that the upper opening of the pan is covered with an inner lid, and the inside of the pan is higher than the normal pressure. It is about 101 ° C. In addition, in the pressure rice cooker, the inside of the pan is further heated to improve the taste, such as improving the stickiness. In other words, when eating as white rice, the temperature is higher than the boiling point and cooked rice that generates a large amount of steam is fundamental.

  On the other hand, in the cooking device for making bread from rice as in the present embodiment, cooking rice is heated to soften and knead raw rice grains on the premise that rice is kneaded after cooking as a bread dough, not rice that eats white rice as rice. Thus, generation of steam can be suppressed as much as possible. In this way, by suppressing the generation of steam and cooking rice for bread dough generation, the gap between the input case 41 and the inner surface of the lid 31 (arrow S1 shown in FIG. 24), or between the outer member 5 and the lid 31 Vapor leaks from a gap (arrow S2 shown in FIG. 24) or a gap (arrow S3 shown in FIG. 24) between the storage chamber 6 and the pan case 7, or steam accumulates in the storage chamber 6 to collect water and become dirty. Or the steam turns around the control unit 30 on which the electronic components for control are mounted, causing the temperature of the electronic parts to rise, or the steam turns around the display body 4 constituting the operation unit 2 to cloud the display body 4. The steam in the storage chamber 6 can be completely discharged from the opening 55 of the lid 3 through the steam port 54 to the outside of the cooker (arrow S shown in FIG. 24).

  On the other hand, the heating configuration as in the present embodiment has the disadvantage that the heating of the object to be cooked is weak, and the water temperature rise in the bread case 7 may be uneven. Specifically, based on FIG. 24, the water temperature in the bread case 7 in the “heating” process at the time of rice cooking is as follows. Due to heat conduction, the temperature is increased in the order of (2) middle side → (3) upper side → (4) upper middle → (5) center → (6) lower middle. Since rice absorbs and gelatinizes as the water temperature rises, in the case of weak heating, the heat conduction time from (1) to (6) becomes longer, and the rice moves as heat moves from (1) to (6). However, in the center and (6) lower middle part, the high temperature time for gelatinization is shortened, and there is a problem that the water for gelatinization is insufficient and the rice becomes hard. . In particular, the center of (5) in the bread case 7 is low in water and the water level is lowered, and the rice becomes hard due to insufficient water absorption. In some cases, the core remains, and (6) the lower middle part in the bread case 7 is Although there is water, the temperature of the water temperature rises slowly, and heating may be insufficient, resulting in insufficient gelatinization. Therefore, the relationship between the temperature of each part in the conventional bread case 7 and time is as shown in FIG.

  On the other hand, in this embodiment, the bread production | generation control means 131 rotates the bread blade | wing 14 during rice cooking, and stirs the water and rice in the bread case 7, and it becomes the temperature increase time difference of the water temperature in the bread case 7. Since the uneven water absorption and pasting are suppressed, even if the inside of the pan case 7 becomes a temperature near boiling and the heating is weakened, the uneven hardness due to the pasting unevenness is reduced, and in the subsequent “kneading” process, When kneaded into bread dough, it is hard and the remainder of rice grains increases, so that it is possible to improve the problem that the taste of bread is lowered.

  For comparison with FIG. 25, FIG. 26 shows the relationship between the temperature and time of each part in the pan case 7 in this embodiment. In this case, the temperature is in the vicinity of boiling from the start of the “heating” step. In the meantime, the temperature difference between the (1) lower side portion and (6) lower middle portion in the pan case 7 is reduced by performing the stirring for rotating the pan blade 14 a plurality of times. Recognize.

  Further, the heating means 8 is used not only for the “heating” process but also for baking bread in the “baking” process, and the heating means 8 is arranged in the lower part of the outside of the bread case 7 as in the conventional bread maker. In a normal rice cooker, the bottom and side lower portions of the pan are heated, and the bottom of the pan is heated to compensate for the disadvantage that the water temperature rise in the lower middle part of the pan case 7 is delayed (6). In the present embodiment, the heating means 8 is used not only for cooking rice but also for baking bread, and the lower portion of the side surface of the pan heater 7 is the main heating source. Although it becomes difficult to gelatinize the center (5) and (6) the lower middle part, it is possible to obtain a practical effect of further improving heating unevenness by the above-described stirring.

  Note that the upper opening of the pan case 7 does not have an inner lid that closes the opening. However, because the inner lid does not exist, the configuration that suppresses the amount of steam generated has a more practical effect. is there. In addition, since there is no inner lid, it is difficult to increase the pressure during rice cooking inside the bread case 7 and the structure tends to cause uneven heating. There is.

  Returning to FIG. 1, in the present embodiment, as a blower that sends air into the storage chamber 6, a cooling fan 27 that is inside the main body 1 and outside the storage chamber 6 is provided, and the wind from the cooling fan 27 is stored. As a circulation device for sending and circulating in the chamber 6, a configuration in which a hole 65 is provided in the side surface of the storage chamber 6 together with the cooling fan 27 is adopted. The hole 65 serves as a blow-off port for the cooling fan 27, and is provided below the middle of the container 6 in order to make the temperature in the storage chamber 6 uniform during heating and to perform cooling after heating. Is preferred. Further, in order to efficiently circulate the heat from the heating means 8, the heating means 8 is preferably disposed below the heating means 8. The hole 65 may be provided not in the main body 1 but in the lid 31.

  Next, details of the operation by the timer cooking control means 135 will be described in detail with reference to FIGS. In FIG. 27, by pressing the start key 3A following the reservation key 3E, the reservation time is set and the timer cooking is started until the end of the “baking” process, which is a baking process. The flowchart is shown. FIG. 28 shows the required time corresponding to the room temperature in each step in the bread making process from the reservation start to the heat retention.

  The control unit 30 of the present embodiment includes two cooking modes in the same cooking course that performs control for baking bread, that is, an immediate cooking mode in which bread making is started as soon as the start key 3A is pressed, and a reserved time. And a timer cooking mode to bake bread at the reserved time. In the immediate cooking mode, the object to be controlled is controlled only by the bread generation control means 131, and in the timer cooking mode, the bread generation control means 131 and the timer cooking control means 135 cooperate to control the control object.

  As shown in FIG. 28, in the bread making process in the timer cooking mode, for example, in the above-mentioned “wheat bread” course, the control of baking bread in the order of knead 1 → nekashi → knead 2 → fermentation → baking → heat retention is bread generation. This is performed by the control means 131. Here, kneading 1, kneading and kneading 2 correspond to the “kneading” step, and the kneading 1 and kneading 2 rotate the pan blade 14 for a predetermined time, but the kneading causes the panning blade 14 to stop rotating for a certain time. Moreover, the bread production | generation control means 131 acquires the room temperature detected by the temperature sensor 29, and controls it so that the time required for each process of kneading, kneading 2, fermentation, and baking may be changed according to room temperature. To control. Specifically, for example, when the room temperature is low (eg, 10 ° C.), the time required for each process of kneading, kneading 2, fermentation, and baking is set longer than when the room temperature is high (eg, 30 ° C.). Is done.

  As shown in FIG. 27, in the timer cooking mode, when reservation starts, the process proceeds to the next step S1, and the timer cooking control means 135 immediately acquires the room temperature detected by the temperature sensor 29. And the bread production | generation control means 131 determines the starting time of kneading 1 from the required time of each process after kneading 1 according to the room temperature acquired at step S1, and controls actual kneading 1 process at the starting time. Is started (step S2).

  When the operation of the kneading 1 is completed, the timer cooking control means 135 proceeds to step S3, and the temperature sensor is set at the kneading 2 start time before the reservation time, which is the longest time from the kneading 2 to the completion (baking completion). The room temperature detected at 29 is acquired again. And the bread production | generation control means 131 determines the starting time of kneading 2 from the required time of each process after the kneading 2 according to the room temperature acquired by step S3 (step S4), and is actually kneaded 2 in the starting time. Control of the process is started (step S5). After this, according to the time required for each process after kneading 2 according to the room temperature acquired in step S3, control by each process of kneading 2, fermentation, and baking is performed (step S6), and bread is generated in the "warming" process. A series of cooking control by the control means 131 is completed.

  FIG. 29 shows a specific setting example of the required cooking time when the user sets the reservation time at 0:00 and starts the timer cooking by the “wheat bread” course shown in FIG. Is shown. If the room temperature is 23 ° C. at the start of the reservation for starting the timer cooking, the timer cooking control means 135 acquires the room temperature detected by the temperature sensor 29 at this time, and from the required time shown in FIG. The total required time of 140 minutes corresponding to “less than 20 to 25 ° C.” is set, and the bread generation control means 131 is started to control cooking for the food to be cooked in the bread case 7.

  Here, it is assumed that the user switches an air conditioner (not shown) installed in the room together with the cooker from on to off at 0:00. The room temperature gradually increases from 23 ° C. at 0:00.

  After that, the bread generation control means 131 is a timing at which the kneading process 1 and the kneading process are completed before the time at which the kneading process 2 starts under the condition that the room temperature is the longest and the room temperature is less than 10 degrees. The operation of kneading 1 is started. In this case, the time required for kneading 1 is based on the room temperature acquired from the temperature sensor 29 at the start of the reservation, and is thus performed for 10 minutes corresponding to “less than 20 to 25 ° C.”.

  Next, the timer cooking control means 135 detects the room temperature detected by the temperature sensor 29 at 4:00, which is the time at which the kneading 2 process starts under the condition that the room temperature required for cooking is the longest and the room temperature is less than 10 degrees. Get it again. Since the room temperature at this time has risen to 30 ° C because the air conditioner is turned off, the total time required for 120 minutes or more corresponding to “30 ° C or higher” is set from the required time shown in FIG. Thus, the bread generation control means 131 performs cooking control for the cooked food in the bread case 7 thereafter. Therefore, the time at which the kneading 2 actually starts is 5:00, which is obtained by subtracting the required time (120 minutes) corresponding to “30 ° C. or higher” from the reservation time, and then the kneading 2 steps for 25 minutes, A 65-minute fermentation process and a 30-minute fermentation process are performed, and bread is baked at 7:00, which is the reservation time.

  In the example shown in FIG. 29, when the room temperature is low (for example, 10 ° C.), the time for light emission and baking performed by the bread generation control means 131 tends to be longer than when the room temperature is high (for example, 30 ° C.). If the specific process is started a certain time before the bread-making completion time, which is the reservation time, without considering the room temperature, it is necessary to make the finished bread coincide with the bread-making completion time, so the room temperature is high. In some cases, the bread can be cooked quickly, and it will be kept warm until the bread making time is reached, during which time the taste will deteriorate.

  In addition, if the room temperature at the start of the reservation for setting the reservation time and instructing the start of timer cooking is acquired and the start time of the specific process is changed, the room temperature is set at the start of the reservation and at the start of the specific process. (For example, the room temperature at the start of the reservation is 25 ° C. and the room temperature at the start of a specific process is 10 ° C.), the process time is extended and the bread cannot be baked at the reservation time.

  However, in this example, for example, the maximum bread making time in a plurality of bread making processes excluding the “Kone 1” process is 180 minutes when the room temperature is less than 10 ° C., and 120 minutes when the shortest time is 30 ° C. or more. In this case, when timer cooking is performed with the reservation time set to 7:00, the temperature is set to 4:00 before the start time of the “Kone 2” process in the bread making process that requires the longest bread making time. The room temperature is acquired from the sensor 29, and if the room temperature is 0 to 10 ° C., for example, if the room temperature is 0 to 10 ° C., the process of “kneading 2” is started immediately, and if the room temperature is 30 to 35 ° C. The process of “kneading 2” is determined at 5:00 one hour later, and the process of “kneading 2” is started from that time, so that the bread generation control means 131 and the timer cooking control means 135 of the control unit 30 are started. It is composed.

  As a result, even when the room temperature around the cooker is different between the start time of the reservation and the start time of the specific process instructing the start of timer cooking by setting the reservation time, the bread can be baked at a time close to the reservation time. Therefore, it is possible to provide a cooking device that can take into account fluctuations in room temperature when performing timer cooking and obtain a stable finished bread.

  As described above, in the present embodiment, the cooling fan 26 is provided as a blower in the cooker that obtains bread dough from the bread ingredients stored in the bread case 7 and throws the powder into the bread case 7 from the charging case 41. Then, the bottom wall of the charging case 41 is constituted by a double-structured opening / closing plate 72 composed of a first lower lid 73 and a second lower lid 74, and cooling is performed between the first lower lid 73 and the second lower lid 74. A cooling air passage 75 through which the air from the fan 26 passes is formed.

  In this case, the wind flowing from the cooling fan 26 flows through the cooling air passage 75 between the first lower lid 73 and the second lower lid 74, so that the bottom wall of the charging case 41 on which the powder is placed is forcibly cooled. Therefore, the rise in the temperature of the powder in the charging case 41 due to the heating of the bread case 7 can be effectively suppressed, and the possibility that the flour hardens or the yeast dies and no longer ferments can be solved.

  In the present embodiment, the pan case 7 and the cooling fan 26 are provided in the main body 1, the input case 41 is provided in the lid 31 that covers the opening of the main body 1, and the air passage opening 78 that communicates with the cooling fan 26 is provided in the main body 1. An air guide port 79 that communicates with the cooling air passage 75 and a steam passage 50 that is an exhaust passage for discharging the steam generated from the inside of the pan case 7 to the outside are provided in the lid 31, and the wind from the cooling fan 26 is supplied to the air passage. The air is introduced into the air guide port 79 from the opening 78 and led to the cooling air passage 75 and is discharged from the cooling air passage 75 through the steam passage 50 to the outside of the cooker.

  In this case, by providing the cooling fan 26 not on the lid 31 but on the main body 1, it is possible to reduce the routing of wiring to the lid 31 and secure a space, thereby simplifying the structure of the lid 31. Further, as the pan case 7 is heated, the thermal effect when the temperature of the lid 31 rises can be avoided, and the temperature rise of the cooling fan 26 can be prevented. Further, the steam from the cooling fan 26 can be safely discharged from the main body 1 to the outside of the cooker while lowering the temperature of the steam passing through the steam passage 50.

  In addition, the first lower lid 73 and the second lower lid 74 in the present embodiment are provided so as to be rotatable around a hinge shaft 76 that is a common hinge portion, and the second lower lid 73 with respect to the first lower lid 73. A fixing member 84 is provided to enable the engagement / disengagement of 74.

  In this case, by sharing the hinge shaft 76 of the first lower lid 73 and the second lower lid 74, the number of parts can be reduced and the cost can be reduced. Further, only the second lower lid 74 can be opened from the first lower lid 73, and the cooling air passage 75 between the first lower lid 73 and the second lower lid 74 can be easily cleaned.

  Further, in the present embodiment, the bottom wall of the input case 41 is constituted by the opening / closing plate 72 as a lower lid provided so as to be rotatable about the hinge shaft 76 that is a hinge portion, and when the opening / closing plate 72 is opened, A brake spring 83 is provided as a brake member that generates a braking force on the opening / closing plate 72.

  In this case, when the opening / closing plate 72 is opened by the brake spring 83, a braking force is generated on the opening / closing plate 72, so that the powder in the closing case 41 is thrown into the pan case 7 without being scattered around the pan case 7. As a result, a cooking device capable of preventing the powder from scattering from the charging case 41 can be obtained.

  In the present embodiment, the angle of the side wall 89 with respect to the bottom wall of the charging case 41 is formed to be vertical or larger than vertical.

  In this case, when the powder is stored in the charging case 41, when the opening and closing plate 72 of the charging case 41 is opened, the powder falls from the side wall 89 of the charging case 41 without adhering. It becomes possible to reliably put the powder into the case 7.

  Further, the charging case 41 of the present embodiment includes a case main body 71 provided with a heat insulating space 87 between a case portion 85 for storing powder and an outer surface portion 86 of the charging case 41.

  In this case, the temperature rise of the powder in the charging case 41 can be suppressed by the heat insulating space 87, and it is possible to eliminate the possibility that the flour hardens or the yeast dies and no longer ferments.

  20 and FIG. 21, the bread case 7 is accommodated in the storage chamber 6 that is a storage container having an open top surface, and the input case 41 is disposed laterally from the top surface of the storage chamber 6. An introduction pipe 111 that guides the powder in the charging case 41 to the pan case 7 may be provided.

  In this case, it is possible to suppress an increase in powder temperature in the charging case 41 by disposing the charging case 41 on the side of the upper surface of the storage chamber 6 while avoiding directly above the storage chamber 6 serving as a heat source. Moreover, in this case, it is only necessary to devise the arrangement part of the input case 41, and the simplification of the cooling structure and the cost reduction can be achieved.

  Further, as in the modification shown in FIG. 21, the charging case 41 may be installed outside the lid 31 that covers the upper surface of the storage chamber 6.

  In this case, it is not necessary to provide the charging case 41 inside the lid 31, the lid structure can be simplified and made compact, and a cooling structure for the lid 31 is also unnecessary, further simplifying the cooling structure and reducing costs. Can be achieved.
