JP 2006-149499 A Japanese Patent No. 2773392 JP 2003-235488 A

  The device disclosed in Patent Document 1 is a container lid in which a motor, a rotary cutter, and a heating rotation mechanism of the heater are all integrated. The entire lid is heavy and difficult to handle, and the heater is exposed. There are also dangers such as burns.

  In both of Patent Documents 2 and 3, a heating base made of a heater is provided at the base of the main body, and the heat generated by heating the heating base with the heater passes through the bottom of the container placed on the heating base. It is intended to be heated.

  However, it is difficult to make the surface shape of the heating table and the surface shape of the bottom of the container coincide with each other, and since all surfaces are not in contact with each other, there is a problem in that heat is not sufficiently transferred into the container and heating efficiency is lowered. In order to increase the heating efficiency, a highly accurate surface shape is required, so the latest attention is required for the processing quality, especially for large-volume products. If the quality deteriorates, the heating process will be different for each product, which will greatly affect the ingredients.

  In addition, since it is necessary to place the container on the base (base) serving as a heating table, a base having a strong surface that supports the container and does not easily deform by handling by the user is required. It is also necessary to have a solid bottom surface that can store food in and stir at high speed with a cutter. In order to use two separate surfaces together, it is necessary to create a container and a base that are both provided with a strong surface. There has also been a problem that it makes it worse or significantly limits the material and design of the container used and the heating table.

  Moreover, for example, in the food processor, the heating process and the stirring and crushing process are also affected in the food processor so that even if the same bean is used in a coffee maker, the heating and drip processes differ greatly depending on the individual products, the taste is greatly affected. If they are different or are not sufficiently controlled, the nutrients will not be extracted without separation, or the ingredients will be mutated to different properties, which will greatly impair the texture and taste.

  However, conventional food processors have not been able to sufficiently control the crushing, stirring, and heating processes for such foods.

  The present invention pays attention to such a problem, enables appropriate heating of foodstuffs, can be crushed and stirred while closely related to the heating, and enhances design freedom for manufacturing and products. The present invention provides a new food processor that is easy to handle and safe.

In order to achieve the above object, the food processor of the present invention comprises a container for storing food, and an electric motor for rotating a stirring body for crushing and stirring the food in the container.
The container has at least a double bottom, and a space for providing heating means is formed between the first bottom and the second bottom of the container,
The container is placed on the base of the food processor body through the second bottom;
The heating means is

A heat transfer section joined to the first bottom of the container;
It is a food processor which consists of a temperature sensor which senses the heat from a heat generation transmission part.

  By configuring in this way, the shape of the container can be freely designed, and the heat generation transmission unit may be joined to the shape of the bottom of the container, and the power supply to the heat generation transmission unit should be a hard cover. Therefore, the degree of freedom for placing the container is also greatly improved. Therefore, it becomes possible to stably heat the container in any shape, and it is possible to control the heating of the food more finely.

Furthermore, the food processor of the present invention, the heat generation transmission part is composed of a heater bonded to the heat conduction part by bonding, embedding, or welding,
The container-side electrical connector is fixed directly or indirectly to the first or second bottom.

  Further, in the food processor of the present invention, the heater is a sheathed heater, and the heat conducting portion is formed of an integral casting in which the sheathed heater is embedded and has a surface coinciding with the outer surface of the first bottom.

  The container-side electrical connector may be directly or indirectly fixed to the second bottom instead of being directly or indirectly fixed to the first bottom. For example, the container-side electrical connector may be fixed to the second bottom. Apart from the thermal fuse, a bracket that supports the container-side electrical connector may be fixed to the second bottom and electrically connected to the heater, thermistor, and thermal fuse provided on the bottom of the container.

  In addition, the first bottom contacting the heat conducting part may be formed separately from the container and joined to the container so as to be configured as the bottom of the container.

  Furthermore, the food processor of the present invention is provided with a screw hole in the second bottom so that the bracket can be screwed to the bracket joined to the first bottom of the container, and the first bottom and the second bottom. And are configured to be coupled by screw tightening.

  The present invention discloses a food processor having a new processing process in a heatable food processor, a container for containing food, an agitator for crushing and stirring food in the container, and heating the container A heating processor and a control circuit for controlling the rotation of the stirrer and the heating by the heating means, wherein the food processor substantially heats the food by the heating means and raises it to a desired temperature. A crushing process for crushing food by rotating the body at a relatively high speed, and after crushing by the crushing process, the stirrer is heated relative to the stirring speed in the crushing process while heating the food by heating means. A first cooking process comprising: an agitation and heating process that continuously or intermittently rotates at a low rotation speed to agitate the ingredients Including.

The first cooking process can be applied to at least one of “soy milk”, “sauce”, and “jam”.
The first cooking process further includes a heating stop and intermittent stirring process in which stirring by the stirring body is intermittently performed while the heating by the heating means is stopped after the stirring and heating process to lower the temperature of the food.

Further, the first cooking process includes a temperature maintaining and intermittent stirring process in which stirring by the stirring body is intermittently performed while intermittently heating by the heating means so that the temperature of the food does not become a desired temperature or lower. In particular, it can be applied to the processing of “soy milk”.
A preheating process for heating without stirring is further provided between the crushing process and the stirring and heating process, which is particularly suitable for the processing of “source” and “jam”.

In addition to the first cooking process, the food processor of the present invention includes an initial simmering process in which, in a relatively early stage, heating is performed by a heating means to start the process of boiling the ingredients by raising the temperature of the ingredients, In the process of lowering the temperature, a second cooking process comprising a crushing process of rotating the stirring body at a relatively high speed rotation in order to finely crush and stir the foodstuff.
Furthermore, the second cooking process of the food processor of the present invention comprises a heat retaining process in which the stirring body is intermittently stirred at a rotational speed lower than the rotational speed in the crushing process to lower it to a desired heat retaining temperature.

  In addition, an additional heating process for temporarily raising the temperature of the food during the crushing process may be included, and the second cooking process can be applied to the process of “soup”.

The food processor of the present invention also includes a third cooking process, and the third cooking process is an initial stage in which the heating means is heated at a relatively early stage to increase the temperature of the food and the food is boiled. It consists of a stew process and a stew heating process that heats intermittently in order to perform the stew process while maintaining the temperature of the ingredients.
The third cooking process further includes an intermittent stirring process in which the ingredients are stirred by rotating the stirring body before the stew heating process, and is applied to at least one of “boiled food” and “rice porridge”. it can.
The first to third cooking processes are pre-programmed according to the finished cooked product suitable for each.

  For example, the first cooking process is suitable for making soy milk. As a result of trial and error by the test, if heat is applied, the soybean component will coagulate and even if pulverized, the soybean component will not spread evenly and finely, resulting in a low concentration of soy milk. More soy component can be extracted.

  In addition, the stirring and heating process of the first cooking process includes time for stirring by continuously or intermittently rotating the stirring body at a relatively low rotation speed, but particularly includes proteins such as soy milk. In the foodstuff, by providing a period for intermittently rotating the stirring member, it is possible to prevent the precipitate from being precipitated and solidified on the bottom of the container and to effectively prevent the precipitated protein from being burnt. In particular, there is no net container such as a basket in the container, so the entire inside of the container, especially the bottom area can be evenly stirred at a low speed, so that it ripens to a mellow texture with no component bias while maintaining a substantial heat retention stage. Can do.

  Thus, in the case where the component required by the material, such as soy milk, is solidified depending on the temperature, or in the case of the material that tends to precipitate the component, the mode in accordance with the basic first cooking process is applied. .

  In specific processing in accordance with the basic first cooking process, how much stirring rotation speed is used or not stirring, and how much heating temperature is used depends on the material to be processed and the finished product. It is programmed differently depending on the product.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view of an embodiment of a food processor 100 according to the present invention, FIG. 2A is an overall perspective view of the food processor 100 with the lid 20 removed, and FIG. 2B is a bottom view of the container 40. 3A is an exploded configuration diagram of the container 40 removable from the main body 20 of the food processor 100, FIG. 3B is a conceptual diagram of the configuration of the cutter assembly 95 used in the container 40, and FIG. 2 is a side sectional view of the processor 100. FIG.

  The food processor 100 includes a main body 20 and a container 40 that can be detached from the main body 20. The main body 20 includes a main body cover (housing) 21, a main body opening / closing lid 10 that is connected to the main body cover 21 so as to be openable and closable, and a base portion 30 that is connected to the main body cover 21 and supports the entire food processor. A cutter assembly 95 for crushing or stirring the food material can be rotatably installed in 40.

  As shown in FIG. 4, the main body opening / closing lid 10 has a motor 11 therein, and is electrically connected to the control board 32 in the base portion 30, and the motor 11 rotates in response to a user operation. .

  As shown in FIG. 3B, the cutter assembly 95 (also simply referred to as “cutter”) includes a cutter shaft portion 92, a cutter shaft portion 92, and a removable cutter portion 93, which are integrally formed. May be. The cutter shaft portion 92 includes a long-extending cutter shaft 98 serving as a rotation shaft, and a motor-side coupling 98a at one end of the cutter shaft 98 on the motor side. The cutter portion 93 is provided with a container bottom side coupling 98b at an end portion in a direction opposite to the motor side coupling 98a. An enlarged knob portion is formed on the container bottom side coupling 98b, and the cutter portion 93 can be attached to or detached from the cutter shaft portion 92 by pinching it with a finger. In this example, the cutter assembly 95 is a knife cutter composed of two blades that are sharp in the rotation direction, extends from the shaft portion to the periphery, and effectively grinds the food material put into the container 40. In addition, the number of blades, the space | interval of a blade, and the direction of a blade can be suitably selected according to the capacity | capacitance of the container 40, the kind of foodstuff to be crushed, etc. A plurality of cutter parts 93 having different shapes can be prepared so that cutter blades 97 having different shapes can be used depending on the processing method of the food material.

  The container 40 is a container for storing the food material to be processed therein. A cutter bearing 59 is provided in the container 40 to support the container bottom side coupling 98b so that it can freely rotate. For example, the cutter bearing 59 has a cylindrical shape protruding from the bottom of the container 40, and the container bottom side coupling 98b is a hole for receiving the cylindrical shape.

  On the other hand, one end of the motor rotating shaft 12 of the motor 11 also has a shaft coupling 12 a that fits with the motor side coupling 98 a, and the rotational force of the motor 11 can be transmitted to the cutter shaft 98. For example, the motor side coupling 98a has a cylindrical shape in which a plurality of grooves extending in the longitudinal direction of the cutter shaft 98 are formed at equal intervals around the cylinder, and the shaft coupling 12a is configured by a hole for receiving the cylinder. A plurality of grooves that engage with the plurality of protrusions of the motor side coupling 98a are formed on the side surface around the hole.

  FIG. 5 is a cross-sectional view of the container 40, the container lid 45, and the lid packing 46 with the cutter assembly 95 installed.

  The container lid 45 and the lid packing 46 are designed to be combined and integrated. The lid packing 46 has elasticity, for example, can be made from a rubber material.

  The container lid 45 that closes the container 40 is provided with a through-hole that allows the motor-side coupling 98a of the cutter 95 installed in the container 40 to pass therethrough. The through hole of the container lid 45 is formed with an inclined portion 47 inclined in the container 40 toward the center of the hole, and forms a tapered surface in the cutter axial direction when viewed from the inside of the container 40. The size of the through hole defined by the tip of the inclined portion 47 is such a size that the cutter shaft 98 passing through the through hole does not alienate the rotation when the cutter shaft 98 is driven to rotate, and the cutter shaft 98 is unevenly distributed. Even if it is mounted in the container 40, the position of the cutter shaft 98 is corrected, and when the main body opening / closing lid 10 is closed, it protrudes from the shaft coupling 12a of the motor rotating shaft 12 and the through hole of the container lid 45. The cutter shaft 98 is guided so that the motor-side coupling 98a can be properly fitted.

  The cutter 95 is provided with a circular splash-proof portion 96 that expands in the radial direction from the cutter shaft 98 so as to be close to the tip of the inclined portion (tapered portion) 47, and in the inclined portion (tapered portion) 47 and in the vicinity thereof. When the food is processed in the container 40 due to the interaction by the provided anti-repelling part 96, a part of the food to be crushed jumps up or the water is scattered by strong stirring to the outside of the container 40. Is effectively prevented.

  That is, since the inclined portion (tapered portion) 47 is inclined in the inner direction of the container 40 from the middle portion of the container lid 45 toward the cutter shaft 98, the inclined portion (tapered portion) 47 can receive food that bounces from the inner wall of the container 40. Splashing from the bottom is prevented by the expanding splashing prevention part 96, and the slanted part (tapered part) 47 and the splashing prevention part 96 are set as a slight gap to prevent the food from bouncing from many directions. The inclined portion (tapered portion) 47 and the splash-proof portion 96 cooperate to prevent leakage to the outside and prevent the food processor 100 and its surroundings from getting dirty.

  The container lid 45 is provided with two water level sensors 48a and 48b. When the container lid 45 is attached to the container 40, the water level sensors 48a and 48b are attached to the container lid 45 so as to be substantially perpendicular to the surface of the water contained in the container 40.

  At least one of the water level sensors 48a and 48b can be folded by a hinge or a screw so that its length can be adjusted. For example, FIG. 4 shows a state in which one of the water level sensors 48a and 48b is folded, and FIG. 5A shows a state in which one of the folded water level sensors 48a and 48b is extended. On the surface of the container lid 45 facing the main body opening / closing lid 10, contact surfaces that are electrically connected to the water level sensors 48 a and 48 b are exposed. On the other hand, the main body opening / closing lid 10 is provided with contact terminals (pins) 13a, 13b for conducting contact in correspondence with the contact surfaces, and the water level sensors 48a, 48b when the main body opening / closing lid 10 is closed. The contact surface is in electrical contact with each of the contact terminals 13a and 13b. Each contact terminal 13a, 13b is electrically connected to a control circuit 32 provided inside the base portion 30.

  A contact terminal (pin) 23 for electrically contacting the bottom of the container 40 is provided from the main body base portion 30 so as to protrude from the base portion 30 so as to expand and contract. The contact terminal 23 is provided at a position where the contact terminal 23 enters the screw hole so that the contact terminal 23 is electrically connected to the head of the screw for coupling to the inner container 50 through the screw hole provided in the bottom of the outer container 60. Yes. As will be described later, in order to connect the outer container 60 and the inner container 50, the conductive container 78 is screwed to the conductive container 78 provided at the bottom of the inner container 50. Therefore, by placing the container 40 on the base portion 30, the contact terminal 23 is electrically connected to the container 40. In addition, the base side contact terminal 23 is electrically connected to the control circuit 32 similarly to the lid side contact terminals 13a and 13b.

  When the container 40 is placed on the base portion 30 and the main body opening / closing lid 10 is closed, the control circuit 32 is urged in the container direction and contacts the contact terminal 23 that is electrically connected to the container through the screw and the coupling portion 78. The connection between the terminals 13a and 13b and the long and short water level sensors 48a and 48b connected to each other is monitored, and the amount of water or the amount of water can be detected depending on the state of conduction.

  For example, the control circuit 32 can determine that the amount of water is excessive when the water level rises to a shorter one of the two water level sensors 48a and 48b. Moreover, when there is no continuity with the longer sensor, it can be determined that the amount of water is small (empty). The water level detected by the water level sensors 48a and 48b can be adjusted by the degree of bending of the foldable sensor. Of course, the length of the water level sensor may be fixed, and the cooking is started only when a predetermined amount of water is satisfied. In addition, since the contact terminal 23 can establish a conductive contact with the container 40, the container can be electrically set to the ground level of the control circuit 32, so that the water level can be stably detected.

  The control circuit 32 is also in electrical communication with the motor 11 and controls the rotation of the motor 11. The load applied to the cutter 95 varies depending on the amount of food in the container 40 and the degree of grinding. In this example, a motor is selected that has a driving capability that can handle loads that can be considered within the range of the allowable amount of food used, but control is performed so that the desired rotation speed can be maintained in advance even when the load changes. The circuit 32 may continuously detect the rotation speed of the motor 11 and automatically increase / decrease the rotation of the motor 11.

  The main body opening / closing lid 10 has opening / closing buttons 13 that can be operated by the user for locking and releasing the opening / closing of the main body opening / closing lid 10 on both sides from the front of the main body 20. When the main body opening / closing lid 10 is closed during operation of the food processor 100, the main body opening / closing lid 10 is locked so that the closed main body opening / closing lid 10 is not accidentally opened. As shown in FIG. 9B, the lock is released by pushing both the left and right open / close buttons 13 inward from both sides, and the lid 10 can be opened by hand while being pushed. If the open / close button 13 is released while the lid 10 is closed, the main body open / close lid 10 will not be inadvertently opened because the spring is biased by an unillustrated spring.

  As shown in the figure, it is preferable to provide the opening / closing button 13 on both sides so that the body opening / closing lid 10 does not open even if one opening / closing button 13 is pushed past. By providing this pair of opening / closing buttons 13, even if one of the opening / closing buttons 13 is closed, the main body 20 of the food processor 100 is not turned on unless the other opening / closing button 13 is closed. The power is turned on when the lid 10 is closed and both the open / close buttons 13 are locked. Conversely, when the main body 20 is in operation and the user wants to turn off the power, the user only has to press one open / close button 13.

  Since the food processor 100 has the motor 11 in the main body opening / closing lid 10, the center of gravity is increased. In order to lower the center of gravity, a power supply board 31, a control circuit 32, an operation panel 35, and the like are provided on the base 30 that supports the main body 20. The power supply board 31 is electrically connected to an electrical outlet, and in operation, the control circuit 32, the operation panel 35, the motor 11, the contact terminals 23, 13a, 13b, the heater 72 provided inside the container 40, and the like. Electricity can be supplied directly or indirectly to electric parts that require electric power.

  If the container 40 is demonstrated, the container 40 is comprised from the container of the two layers of the inner container 50 and the outer container 60 largely.

  The outer container 60 of the container 40 is provided with a handle 66 that can be held by a person's finger. The outer shape of the container 40 is a substantially quadrangular prism with a mouth that can be closed by a container lid 45 opened upward, and the four corners form a substantially loose R when viewed from above (that is, in the direction of the opening).

  A container housing area is formed between the main body opening / closing lid 10 and the base portion 30 so as to match the outer shape of the container 40. With the main body opening / closing lid 10 in an open state, the container 40 can be held by the handle 66 and placed on the base portion 30 in the container housing area inside the main body 20 from a space that is wide open toward the front of the main body 20. . FIG. 9A conceptually shows a procedure for placing the container. In FIG. 9A, for easy understanding, the main body opening / closing lid 10 is shown in a closed state. However, in order to place the container 40, the main body opening / closing lid 10 must be in an open state.

  The main body cover 21 that connects the main body opening / closing lid 10 and the base portion 30 has a container 40 so that the container 40 can be guided to an appropriate mounting position by inserting the container 40 from the wide front opening from which the main body opening / closing lid 10 is opened. It has an internal shape that matches the shape of the outer peripheral surface.

  As will be described later, the base-side electrical connector 34 protrudes from the upper surface of the base portion 30 that is the surface on which the container 40 is placed, and the connection portion is exposed. On the other hand, a container-side electrical connector 74 having an exposed connection portion is provided on the bottom of the container 40. It is preferable that the container-side electrical connector 74 does not protrude from the bottom of the container 40 so that the container 40 can be stably placed on a flat portion. When the container 40 is placed on the base portion 30 along the guiding shape of the main body cover 21, the base-side electrical connector 34 and the container-side electrical connector 74 are fitted and electrically connected.

  That is, the main body 20 has an inner wall shaped so as to come into contact with or close to the surface around the side surface of the container 40, and the container 40 and the main body 20 are combined so as to have an appropriate positional relationship. Can be easily placed on the main body 20.

  The container 40 has an inner container 50 and an outer container 60. The container 40 is mainly used as a container for effectively heating, pulverizing, and stirring while introducing the food to be processed into the container. The inner container 50 can be formed from stainless steel, such as SUS, and has a coating treatment such as fluorine coating on the surface. On the other hand, the outer container 60 has an appearance as a product, is provided for easy handling and handling by the user, and accommodates the inner container 50 to form a surface on which the container can be placed in addition to the bottom of the inner container 50. It has 2 bottoms. A space 90 is provided between the second bottom and the bottom of the inner container 50. Using this space, electric power is received from the base portion 30 and converted into heat to supply the heat to the bottom of the inner container 50. A heating means can be provided.

The mechanism for heating the inside of the inner container 50 will be specifically described below.
FIG. 8 is a block diagram showing a configuration example of the control circuit (control unit) 22 in the control board 32 and its peripheral devices. The control circuit 22 has a microcomputer 24 and a motor drive circuit 26 that controls the drive of the motor. The microcomputer 24 is connected to the operation panel 35, various sensors 27 such as a temperature sensor and a motor speed sensor, an input / output (I / O) circuit 24a connected to the motor drive circuit 26, a CPU 24b and a memory 24c (ROM). RAM) and a bus 24d for connecting them. In the memory 24c, a program for executing processes consisting of various processes determined based on the basic operation profile shown below and various parameters for execution thereof are recorded. Although not shown here, the power supply to the heater by ON / OFF control of the heater is also controlled by the microcomputer 24 of the control circuit 22. If there is only one switch, the switch may be turned on even when the opening / closing lid 10 is pushed obliquely. In this case, even if the rotation shaft 12 of the motor and the motor side coupling 12a are not completely fitted, the motor will operate and cause abnormal noise or failure. Therefore, as described above, the open / close lids 10 on both the left and right sides of the open / close lid 10 have a role of switches, and by connecting them in series, the open / close lid 10 is pushed obliquely and closed by tilting. In such a case, the power supply operation is prohibited.

  On the upper surface of the base portion 30 on which the container 40 is placed, a base-side electrical connector 34 that is electrically connected from the power supply substrate 31 is provided. On the other hand, in a space 90 that occupies between the bottom of the inner container 50 and the bottom of the outer container 60, a heating assembly 70 for heating the bottom of the inner container 50 and transferring heat to the inside of the inner container 50 is provided. .

  The outer container lower part 80 and the outer container upper part 65 are integrally formed of a resin such as polypropylene resin (PP resin), for example. FIG. 6 shows the bottom part of the outer container 60 (hereinafter referred to as “outer container lower part 80” for convenience). Is removed from the upper portion 65 of the outer container to expose the bottom surface of the inner container 50, the heating assembly 70 attached to the outer surface of the bottom of the inner container 50, the temperature sensor 77 provided around the heating assembly 70, and the outer container 60. 2 shows a sensor terminal block 76 and four coupling portions 78 each made up of a bracket (mounting bracket) for connection to the inner container 50.

  The heating assembly 70 can be composed of a heat generation transfer section including a heat conductor 79 and a heater 72, and a container-side electric connector 74 that is supported by the heat conductor 79 and electrically connected to the heater 72. The thermal conductor 79 may be provided with a thermal fuse for cutting off power to the heater 72 when an abnormal temperature is reached.

  By using the integrated heating assembly, the heating assembly can be fixed to the container as it is, and the trouble of separately mounting the container-side electrical connector is reduced.

  Adjacent to the periphery of the heating assembly 70, a thermistor 77 serving as a temperature sensor via a welded attachment plate, a sensor terminal block 76 supporting the sensor terminal, and an outer container 60 are provided on the periphery of the bottom of the inner container 50. In order to connect the inner container 50 and the inner container 50, a connecting portion 78 is provided in which a screw is stopped.

  The heat conductor 79 is formed so as to substantially match the surface shape of the bottom of the inner container 50 so that the heat conduction is effectively transmitted to the inner surface of the inner container 50 through the bottom of the inner container 50. For example, the heat conductor 79 has a surface in contact with the outer surface of the bottom of the inner container 50. The heater 72 and the heat conductor 79 can be integrally formed by casting. For example, by casting a metal such as aluminum by, for example, die-casting or gravity method so as to embed a circumferentially extending heater parallel to the plane, one surface coincides with the joint surface of the bottom of the container 40 It is possible to provide a substantially flat plate-like heat generation transmission member. By using a sheathed heater as the heater 72 and casting and embedding the heater, heat generated in surface contact with the heat conductor 79 can be efficiently transmitted to the bottom of the inner container 50.

  If heat can be effectively transferred to the heat conductor 79 fitted to the bottom outer surface of the inner container 50, the heat conductor 79 is attached to a metal plate such as SUS by another method of casting, for example, adhesion or welding. It may be bonded and integrated with the heat conductor 79.

  The size of the heat conductor 79 may be a size that fits within the bottom surface of the inner container 50, and can be easily matched to the shape of the surface of the inner container 50.

  For example, the heat conductor 79 is welded to the bottom of the inner container 50, and the entire heating assembly 70 is attached to the bottom of the inner container 50. In addition to welding, as long as the heat conductor 79 can be reliably bonded to the bottom of the inner container 50, any bonding method such as bonding or screwing may be used.

  Further, the heat conductor 79 may be joined to the bottom of the inner container 50 while sandwiching a flat sheathed heater tightly between the heat conductor 79 and the outer surface of the bottom of the inner container 50.

  With reference to FIGS. 12 and 13, an example of a method for attaching the heat generation transfer member in which the heater 72 and the heat conductor 79 are integrally formed to the bottom of the inner container 50 will be described.

  FIG. 13A is a side sectional view showing a state where the cutter bearing 59 and the heat conductor 79 are fixed to the inner container bottom 51 that closes the opened bottom of the inner container 50, and FIG. 13B is a bottom view thereof.

  As shown in FIG. 12, an opening is formed at the bottom of the inner container 50 to form a bottom opening edge 50 a of the inner container 50. A plate-like inner container bottom 51 that closes the opening is prepared separately. A peripheral edge of the inner container bottom 51 is provided with an edge 51a so that it can be joined to the surface of the bottom opening edge 50a of the inner container 50 by a method such as welding, and the bottom opening edge 50a of the inner container 50 By joining the peripheral edge 51a of the inner container bottom 51 around, the bottom of the inner container 50 closed by the inner container bottom 51 is formed. The inner container bottom 51 is preferably the same as the material of the inner container 50, and can be formed from stainless steel such as SUS, for example.

  A hole through which the cutter bearing 59 can pass is provided at the center of the inner container bottom 51 and the center of the heat conductor 79. As described above, the heater 72 and the heat conductor 79 are integrally formed so as to be compatible with at least a part of the outer surface of the inner container bottom 51, and become the first bottom part of the inner container 50. The bottom 51 is integrated with the joining direction such as welding or adhesion. The tip of the cutter bearing 59 is threaded, and the tip of the cutter bearing 59 that passes through the through hole formed in the center of the inner container bottom 51 and the center of the heat conductor 79 is screwed from the opposite side via a sealing material. And the inner container bottom 51, the heat conductor 79, and the cutter bearing 59 are integrated.

  By opening the bottom of the inner container 50 and individually providing the inner container bottom 51 that closes the opening, the heat conductor 79 can be more closely coupled to the inner container bottom 51. In particular, by forming the inner container 50 individually as a small solid, it becomes easier to match the surface shape of the heat conductor 79. Further, the inside of the container usually requires a coating such as a fluorine coating. However, if there is a coating on the surface on which the cutter assembly 95 abuts and slides, it will peel off at that portion, which is not preferable. Therefore, after the inside of the container 40 is coated, the cutter bearing 59 is screwed to a heat generation transmission member, which is a separate member, so that the cutter bearing 59 is not coated.

  Returning to FIG. 6, in the region around the opening edge 50 a at the bottom of the inner container 50, coupling portions 78 are provided in four directions. On the other hand, as shown in FIG. 2B, the outer container lower portion 80 is provided with a plurality of holes through which screw shafts for screwing pass corresponding to the positions of the coupling portions 78. Each of the plurality of coupling portions 78 is provided with a threaded hole for receiving a screw shaft, and the outer container 60 is fixed to the inner container 50 by being screwed to the coupling portion 78 through the hole in the outer container lower portion 80. The

  FIG. 6 shows a state in which a screw is attached to a part of a coupling portion 78 for screw coupling between the outer container 60 and the inner container 50.

  The container-side electrical connector 74 is a connector for receiving electric power from the base-side electrical connector 34 of the base portion 30 and supplying it to the heater 72. The outer container lower portion 80 is provided with a hole that allows the container-side electrical connector 74 to be exposed from the bottom of the container 40 to the outside and to be coupled to the base-side electrical connector 34.

  The thermistor 77 is for preventing excessive heating by the heater 72 and supplying the desired heat appropriately. The control circuit 32 sends a resistance change signal from the thermistor 77 to the container-side electrical connector 74 and The temperature is adjusted by controlling the supply of electric power to the heater 72 received through the base-side electrical connector 34. In addition to preventing excessive heating, it is also possible to detect cases where scheduled heating is not possible due to disconnection of the heater or the like. In addition, the thermal fuse 71 is provided in preparation for the case where the heat rises abnormally, and can receive the excessive heat from the heat conductor 79 to cut off the supply of electricity to the heater 72. Yes.

  The thermistor 77 is not directly joined to the heat conductor 79, but is joined to a metal (SUS) mounting base having good thermal conductivity, which is joined to the bottom of the inner container 50 around the heat conductor 79. It becomes possible to monitor the temperature inside. On the other hand, by joining the thermal fuse 71 to the thermal conductor 79, it is possible to quickly cope with excessive heat from the thermal conductor 79.

  An air filter 82 such as a vent filter is provided inside the bottom of the outer container lower part 80 (that is, the side facing the bottom of the inner container 50) so that air can flow between the outside and the space 90. I have to. The air filter 82 regulates the air pressure between the outer container upper part 65 and the outer container lower part 80 and suppresses intrusion of water from the outside into the space 90 part, and ensures air circulation to reduce internal corrosion.

  In the above example, the structure in which the bottom of the inner container 50 is opened and the inner container bottom 51 is separately provided and joined has been described. However, if the object of the present invention can be achieved, the bottom of the inner container 50 is not opened. The heat conductor 79 may be directly joined to the bottom of the inner container 50.

  In the previous example, the heat conductor 79 has a role as a base for supporting the container-side electrical connector 74, but the function as the base is given to another element, and the heat conductor 79 moves to the bottom of the inner container 50. You may make it specialize in the function as a heat conduction. By doing so, the heat conductor 79 can be made softer or thinner metal instead of hard metal, and can be more flexibly adapted to the surface to be joined to the bottom of the inner container 50. As a support for the container-side electrical connector 74, a new bracket may be used to join the bottom of the inner container 50.

  As can be understood by those skilled in the art from the above description, the outer container lower part 80 and the outer container upper part 65 may be separated and molded separately, and the outer container lower part 80 may be a cover that covers the bottom of the container 40 containing the foodstuff. And you may make it fix the bracket which supports the container side electrical connector 74 inside a cover.

  When a hard bracket is fixed inside the bottom of the separable outer container lower part 80 serving as a cover, the container-side electrical connector 74 and the heater, thermistor, and thermal fuse of the heat conductor 79 are flexible and have a heat-resistant coating. It is possible to connect with an electric wire covered with, and when the cover is attached, the electric wire is folded into a space formed between the double bottoms.

  The heat conductor 79, which is an element of the heat generation and transmission section, can be made of metal, or any kind of material as long as it has heat resistance and high heat conductivity and can be joined to the outer surface of the container bottom where heat is applied. It may be a flexible heat conductive sheet or heat conductive plate. The joining method of the heater, which is an element of the heat generation transfer section, can be selected from possible joining methods such as adhesion or sticking, embedding in the heat conduction plate, welding, caulking, etc. Depending on the hardness of the inner wall 50, a hard bracket for supporting the container-side electrical connector 74 may be fixed to the inner container 50, or may be supported by the heat conductor 79 without using such a bracket, It can be arbitrarily selected whether to fix to the inside of the bottom of the container lower part 80.

  Thus, the container-side electrical connector 74 can be reliably fitted to the base-side electrical connector 34 and efficiently apply heat from the heat conductor 79 to the container bottom to be heated. Whether the container-side electrical connector 74 is fixed directly or indirectly to the bottom on the inner container side or directly or indirectly to the bottom on the inner container side depends on the size of the heating assembly 70 excluding the container-side electrical connector. It can be determined according to the sheath position, shape, and degree of space 90.

(Food processing process)
Next, the process of food processing will be described.
In order to process the food material, the cutter 95 is attached to the container 40 removed from the main body 20 by the method described above, and the food material to be processed is cut into the container 40, preferably into a size within several centimeters. The lid packing 46 is attached to the container lid 45 in advance, and is attached to the container 40 so that the tip of the cutter shaft 98 comes out of the hole of the container lid 45 and the hole of the lid packing 46. With the main body opening / closing lid 10 of the main body 20 opened, the container 40 is installed on the base portion 30 so that the base-side electrical connector 34 and the container-side electric connector 74 are fitted, and the main body opening / closing lid 10 is secured. set.

  In this product, soup and soy milk in which the solids are fluidized, soup that gives a feeling of eating that leaves some of the shape of the ingredients (hereinafter referred to as eating soup), processing that makes the ingredients sticky, for example, You can make porridge, etc.

  Furthermore, without using any heat, chopping, surimi, minced, crushed, liquefied, blended liquid, kneaded dough such as bread, crushed, shredded, grated, whipped You may make it also serve as food processors, such as making cream and meringue.

  7 shows an example of an operation panel 35 that is provided in front of the base portion 30 and receives an operation from the user and indicates an operation state, a processing state, an alarm, and the like to the user. .

  Needless to say, processing that further expands the types of processing of the ingredients is also possible, and input and display that can accept more operations that can be processed may be performed on the operation panel 35. For example, communication with a smartphone or tablet is possible, and the range of food processing can be greatly expanded.

  Returning to this example, an example of heat treatment newly disclosed and particularly effective in the present invention will be described below.

A plurality of operation buttons 36 are prepared on the operation panel 35.
It shows finished dishes such as “smooth soup”, “eat soup”, “rice porridge”, and “soy milk”. The light is turned on by pressing each button.
In addition, the operation panel 35 has a status indicator 38 indicating the completion process so that the user can visually recognize the current situation. Further, an indicator 39 indicating the heat insulation state of the dish is also prepared.

  A plurality of indicators 37 for displaying various alarms are also provided. The contents of the alarm differ depending on the combination of the plurality of indicators 37.

In accordance with each operation button 36, the rotational speed and operating time of the cutter assembly 95 according to the recipe, and the temperature management conditions by the heater are programmed in the control circuit 32 in advance.
Hereinafter, processing of the control circuit 32 according to the operation on the operation button 36 will be described.

(Control processing according to the first embodiment)
(Soy milk)
FIG. 10 shows an example of an operation profile when the soy milk button is pressed, and FIG. 11 shows an example of an operation profile when the smooth soup button is pressed.

  In the figure, the vertical bars dotted on the horizontal axis of the motor indicate when the motor is ON, the height indicates the relative magnitude of the motor speed, and the time axis on the horizontal axis It is shown as a guide to clarify the concept of the profile. In addition, vertical bars scattered on the horizontal axis of the heater indicate when the heater is ON.

  Referring to FIG. 10, when the soymilk operation button 36 is pressed, the motor first rotates at a relatively high rotational speed. This initial rotation is the initial process of grinding soybeans. When it was pulverized with a high-speed cutter after heating, it was found that the soybean component coagulated, and the soybean component could not be extracted in a soup-like manner, so the process starts from an initial process of pulverizing at a low temperature. The rotation speed per minute of the cutter assembly 95 in the initial process is 4500 to 5500 rpm at the maximum, and is switched on and off in units of several seconds. Move.

  When the crushing is completed and the process proceeds to the second process, the intermittent operation by the heater 72 is performed next, and the rotation of the agitation motor 11 is decreased while the temperature is gradually increased, and the continuous operation is performed. The heater 72 is intermittently operated for 4 seconds OFF and 2 seconds ON to heat slowly. When it is detected that the temperature exceeds 90 degrees, the heater 72 is turned off, and the heater 72 is controlled while monitoring the temperature so that the temperature is maintained at or near 90 degrees. Thus, the soy milk can be prevented from coagulating and scorching by intermittent operation of the heater 72 and low-speed continuous operation of the motor. When this process is performed for a predetermined time, for example, 15 minutes, soy milk is almost finished. Thereafter, the process proceeds to the third stage, which is the next stage.

  The third process is an introduction process to the heat insulation process, and the heater 72 is completely stopped until the temperature becomes 70 degrees or less while continuing the intermittent operation of turning the motor on for 5 seconds / off for 15 seconds during the process. Further, as a heat retention process, when it is detected that the temperature is cut off 70 degrees, the temperature is increased while the heater 72 is intermittently operated. When the temperature exceeds 70 degrees, the heater 72 is turned off. Repeat the process of raising the temperature while intermittently operating.

  As described above, the temperature sensor can be monitored at a temperature close to the temperature at the bottom of the container because the temperature sensor is placed on the bottom of the container right next to the heater. Therefore, in the introduction process to the heat retention process, even if the heater is completely turned off, the temperature can be continuously monitored more accurately than in the past, so the cutter blade 97 located near the bottom of the inner container 50 is intermittently connected. As long as the temperature is made uniform by a typical rotation, the dish can be transferred to the subsequent heat insulation process without changing the quality. If the temperature is lowered by heating from time to time with a heater in a high temperature state, the time at a relatively high temperature becomes longer, which greatly affects the taste of the dish. In addition, since it has not been possible to monitor at a sufficiently accurate temperature in the past, even if the heater is turned off and kept warm, the temperature of the food is unnecessarily reduced, and a large amount of heat is given to warm it up. However, the present invention can solve such a problem, although the taste and touch of cooking are greatly hindered.

  If the heat retention is continued for a certain time and exceeds the certain time, the heat retention process is terminated and the power of the food processor 100 is also turned off.

(soup)
Unlike soy milk, smooth soup (soup to drink), soup to eat, and rice porridge have the same basic profile, except that the conditions of intermittent operation of the motor are different in the cooking process before the heat insulation process. It will be explained together.

  After heating by heater 72 and detecting 95 degrees or more, after ON and OFF are intermittently repeated for a predetermined time thereafter, heater 72 is turned OFF, the first process of boiling by heating is terminated, and the second process is started. .

In the second process, the motor is intermittently operated and pulverized. At this time,
In “Smooth Soup”, 5 seconds ON / 10 seconds OFF 30 times + 20 seconds ON / 10 seconds OFF 2 times, rotation speed is 4500-5500 rpm,
In “eat soup”, 5 seconds ON / 10 seconds OFF 3 times, rotation speed is 400-600 rpm,
In “Okayu”, 0.5 seconds ON / 1 second OFF 3 times + 2.5 seconds ON once, rotation speed is 400-500 rpm,
Drive on.
Thus, the soup and the like are completed, and then the third step is performed.

  The third step is an introduction process to the heat insulation process, and the intermittent operation with the motor turned ON for 5 seconds / OFF for 25 seconds and the rotation speed of 400 to 600 rpm is continued during the process until the temperature becomes 70 degrees or less. The heater 72 is completely stopped.

  When it is detected that 70 degrees have been cut, the process proceeds to a heat retaining process, the temperature is raised while intermittently operating the heater 72, and when it exceeds 75 degrees, the heater 72 is turned off. Repeat the process of raising the temperature while intermittently operating.

  As a result, the heat retention is continued for a certain period of time, and when the predetermined time is exceeded, the heat retention process is stopped and the power of the food processor 100 is also turned off, thereby preventing deterioration of the taste of the ingredients due to excessive heat retention. can do.

  As shown in FIG. 10 and FIG. 11, depending on the material to be processed and the finished product, there are different basic profile categories such as first stirring and crushing, or crushing after heating and steaming. It is prepared.

  As described above, the food processor of the present invention has at least a basic first processing profile as a processing process, and the first processing profile is before the substantial heating of the food by the heating means. A first process including a process of crushing food by rotating a stirring body that is a cutter assembly 95 at a relatively high speed, and after crushing by the first process, heating by heating means is performed so that the temperature is close to a predetermined temperature. And a second process including a process of continuously rotating and stirring the stirring member at a relatively low rotational speed while raising the temperature.

  In addition to the basic first processing profile, the second processing profile has a basic second processing profile. The second processing profile is a process of heating the food to a predetermined temperature by heating with heating means and boiling the food. And a second process including a process of crushing the food by intermittently rotating the stirrer while the heating by the heating means is stopped and the temperature of the food is lowered. It is also possible.

  Further, in the food processor of the present invention, the first processing profile intermittently rotates the stirring body at a lower rotational speed than the rotation in the first process while the temperature is decreased from the temperature increased in the second process by stopping heating. It is also possible to further include a third process including a process of stirring and lowering to the target heat retention temperature.

  The food processor of the present invention further reduces the rotation of the stirring body from the rotational operation to the next while the second processing profile is lowered from the temperature of the second process to a lower temperature while heating is stopped. It is also possible to include a third process including a process of intermittently rotating the stirring member at a time interval with a longer time until the rotating operation.

  In addition, the food processor of the present invention has a basic third machining profile, the basic third machining profile being combined after the basic first machining profile and the second machining profile, or The third processing profile can be operated independently, and may include a process of intermittently heating so as to maintain a predetermined temperature and intermittently rotating the stirrer in parallel.

  The processing mode for the first processing profile and the processing mode for the second profile are programmed in advance according to the finished product for the food. And by providing the said different basic process profile, according to the finished product obtained from the foodstuff used as a process target, an appropriate process can be performed now.

  In addition to the basic profile, a basic profile obtained by removing the heat retention process from the basic profile is also prepared. A program for processing based on the basic profile is stored in the control circuit 22 and executed. Based on the basic profile, specific processing modes such as how much heating is required and how often intermittent stirring is performed or not depending on the finished product are preset. When programmed, the user can press the finished product to execute a specific processing mode based on the concept of its basic profile and make a more delicious dish.

(Control processing according to the second embodiment)
If a plurality of fine touch buttons are provided on the operation panel, it is difficult to visually recognize and the usability deteriorates. On the other hand, if a plurality of cooking is possible as a food processor, the function of the product is improved, and various processed foods can be provided by one apparatus. Therefore, it is necessary to expand the variety of types of processed foods while maintaining the form of the operation panel for facilitating user access.
Therefore, as a result of further studies, the inventor has come to be able to perform control processing using a pattern different from that of the first example.

FIG. 14 shows an operation panel 35 ′ according to a new second example in place of the operation panel 35 of FIG.
Although the point which has the four operation buttons 36 is the same, in three operation buttons 36, the name as processed food is changed. Depending on the name change, the specific processing profile differs.

In FIG. 7, the two operation buttons 36 next to the operation button 36 for soymilk are buttons for separately processing “Okayu” and “eat soup”. On the other hand, in the second example of FIG. 14, it was found that the separate processing of “Okayu” and “eat soup” can be unified into one processing.
As already mentioned, “Okayu” and “eat soup” have different parts as a specific processing process, but the inventor's research has found that the basic profile is the same. . Therefore, if the basic profile is used to change to a different basic profile, it may be possible to create a unified specific processing process based on the new basic profile. .

  From such an idea, what is summarized in a specifically unified processing process is the so-called “boiled food / rice porridge” in FIG. In other words, by using the new basic profile, it has become possible to create a specific processing process for “boiled food” that can be processed with the operation buttons together.

  Here, the basic profile in FIG. 11 is the first process that is an initial simmering process in which the ingredients are raised to a predetermined temperature by substantially continuously heating with the heating means, and the heating by the heating means. And a second process including a process of crushing the food by intermittently rotating the motor that drives the cutter assembly 95 in the process of lowering the temperature of the food and lowering the temperature of the food.

However, the ingredients tend to be somewhat soft even in the initial warming and boiling stage, and if the rotation of the stirrer is intermittently rotated after the initial stage of cooking, the ingredients can be scraped slightly. It was found that the seasoning was mixed, and the shaved portion could be dispersed to the whole taste, and it could be mixed without losing the shape and feeling of eating. Therefore, after making such a stirring state, if the heater can be further intermittently heated so that the temperature can be maintained as long as possible, the taste is also dispersed throughout and the flavor of the seasoning penetrates into the ingredients, It was found that rice cakes that are not too sticky can be made, and that a more tactile feel can be maintained.
Such tactile sensation can be applied to other types of processed foods in the same way. It came to.
From such research, the “boiled soup” and “boiled soup” in FIG. 7 can be combined into one, and cooking processing as “boiled” is also possible, so the “boiled / boiled” button as a new operation button 36 Is provided.

(Processing of “boiled foods / rice porridge”)
An example of a specific processing process of the “boiled food / rice porridge” is shown in FIG.
Similarly to FIGS. 10 and 11, in FIGS. 15 to 17, the vertical bars dotted on the horizontal axis of the motor indicate the motor ON, and the height thereof is the relative magnitude of the motor rotation speed. Is shown as a guide, and the time axis on the horizontal axis is also shown as a guide for the passage of time. In addition, vertical bars scattered on the horizontal axis of the heater indicate when the heater is ON. In addition, even if the vertical axis of the motor ON is shown as a thin line due to the size limitation of the drawing, it is only shown as an ON as a guide, and it is not necessarily limited to only one ON. It should be noted.

The processing process for processing into “boiled food / rice porridge” is the same as the conventional one in that it has a first process consisting of an initial heating and boiling process in which the ingredients are heated to a predetermined temperature by heating with a heater. To do.
In the relatively early cooking process, even if the heater is turned on continuously and the water temperature in the container is quickly raised to start cooking, it can be fully cooked. It is good also as processing. However, when it is boiled for a long time by the boiling process of initial heating, since it will become easy to cause a shape loss by stirring of the cutter assembly 95 which is a subsequent stirring body, it is not preferable.

  The first process secures a predetermined time for the initial heating boil process, and is set to 8 minutes 30 seconds in this example. If the heater exceeds 90 degrees during the time, the heater is turned off and the heater is controlled so that the temperature can be maintained around 90 degrees. By controlling near 90 degrees, it was found that the whole ingredients would not collapse, and the taste penetrated well so that delicious cooking could be done. In this example, the water temperature was 88 degrees or less, and the water temperature was 88 degrees or less. The heater is controlled to do so. That is, when the temperature is 88 degrees or less, the heater is turned on. When the water temperature rises to 90 degrees or more, the heater is turned off. When the water temperature is lowered and the water temperature falls to 88 degrees or less, the heater is turned on. By performing this intermittent repetition, the water temperature is made as constant as possible. In the case where the fine control as described above for making the temperature constant is impossible, the heater is preferably controlled within 85 degrees to 95 degrees, more preferably 88 degrees to 92 degrees, and the first process. The total time is preferably about 7 minutes 30 seconds to 9 minutes 30 seconds.

Thus, continuous heater does not mean that it must be continuous throughout the entire first process (8 minutes 30 seconds in this example). In order to enable cooking while shortening the overall processing time as much as possible, in the initial heating, the heater is turned on substantially continuously to increase the water temperature. If the simmering process is possible, the intermittent operation may be performed in which the heater is turned off for some time.
When the initial heat treatment is finished, the process proceeds to the second process which is a phase for full-fledged boiled heat treatment. The second process may include a steaming process after the simmering process, and is programmed in advance so that the second process ends in a predetermined time after the initial simmering process is started. In this example, the total processing time is about 28 minutes.

  The second process is a process of stirring the ingredients as a whole while mixing the ingredients a little while pulverizing the ingredients a little, and simmering them with heat, and intermittently operating the motor and maintaining it at a desired temperature. Two processes with typical heater operation are included.

  In the food processor of the present application, the temperature sensor indirectly detects the water temperature and the temperature of the food, but in order to perform intermittent heater operation, the water temperature and the temperature of the food are indirectly or directly controlled. When it is detected that the temperature sensor to be detected is lower than a certain temperature, the intermittent operation of the heater is turned on, and when it is detected that the temperature is higher than a certain temperature, the intermittent operation of the heater is turned off. Note that the heater is turned ON for a predetermined time and the same time or OFF for a different time as one set, and intermittent operation is turned ON, that is, the ON and OFF set is turned ON once or repeatedly. It is possible to avoid an extreme rise in temperature by turning off the normal operation, that is, by repeating the ON / OFF repeated operation and turning off the heater.

The temperature range in which the intermittent operation of the heater is turned ON / OFF in the boiling process of the second process is programmed in advance. In this example, 90 degrees is the lower limit temperature and 95 degrees is the upper limit temperature, and the intermittent operation is controlled for 5 seconds ON / 5 seconds OFF, but the sensitivity of the sensor, the temperature measurement position by the sensor, etc. Since the appropriate temperature managed as a sensor differs according to the above, it may be changed or adjusted as appropriate.
Preferably, at a relatively early stage of the second phase, the food is somewhat shaved, but rather the cutter assembly 95 is interrupted primarily for the purpose of mixing the ingredients with the ingredients being agitated. The motor is turned on for a predetermined time so as to rotate automatically, and intermittent operation is performed in which the motor is turned off for the same time or different time. For example, by using intermittent operation such that 5 seconds ON / 5 seconds OFF is set as one set, it is possible to avoid that the food is extremely crushed, and by providing an OFF rest time, the weight of the food can be reduced. Due to this, the ingredients are mixed more uniformly. Moreover, the part grind | pulverized from the foodstuff is disperse | distributed as a taste to the whole.

In order to keep the temperature until the end of cooking in the second process as constant as possible, the intermittent operation of the heater described above is performed at least after the intermittent operation of the motor or in parallel with the intermittent operation of the motor. Thus, fine temperature control becomes possible by the intermittent operation at the time of the simmering process, and the temperature can be kept constant. Thereby, in combination with the effect of the sensing accuracy of the temperature sensor as described above, in the food processor of the present example, the temperature just before the boiling state where the steam diffuses (90 ° C. to 95 ° C. depending on the cooking menu) This makes it possible to control the system with ease and improves usability, such as safety and selection of the location.
In FIG. 15, before the motor is intermittently operated, 5 seconds ON / 5 seconds OFF of the heater is inserted once, and the boiling process by heat insulation heating is added as a sub-process in the second process. However, if the temperature already exceeds 95 degrees, the heater is not turned on.
The intermittent operation of the motor is a set of 5 seconds ON / 5 seconds OFF, and a relatively low rotation speed, for example, the ON motor is set to a predetermined number of times at a rotation speed set to 400 to 600 rpm, for example, ON / OFF in this example. Repeat 5 times. This also stirs the seasoning.

In the stew process of the second process, an intermediate heat treatment is then performed to further boil the stirred food. The intermittent operation of the heater for 5 seconds ON / 5 seconds OFF is repeated 96 times, and the heat treatment is performed for about 16 minutes. However, when the water temperature is 95 degrees or more, the heater is not turned on.
It should be noted that stirring by the cutter assembly 95 is not performed so as to substantially simmer in the boiling process by heating of the heater that occupies a large portion of the entire time.

At the end of the second process, the intermittent operation of the heater is also turned off, that is, the heater is turned off, and the steaming process is performed for 120 seconds to complete the process.
As described above, by the heat treatment without stirring in the first process, the stirring process by the motor in the initial stage in the second process, and the temperature-controlled stew processing by the intermittent operation of the heater after that, In addition, it is now possible to carry out so-called “eat soup” with a single processing button, which can give rice porridge and a feel to eat.

(Processing of “potage”)
As already described, “smooth soup” in FIG. 7 has the same basic profile as “eating soup”. However, since the specific processing process is slightly different, another operation button 36 is provided as “potage”. The specific process will be described below.

An example of a specific processing process of the “potage” is shown in FIG.
The processing process for “potage” is the same as the processing process for “boiled foods / rice porridge”. The first heating process consists of an initial heating process in which the food material is heated to a predetermined temperature substantially continuously by heating means using a heater. It is common in having the process of. For example, in the initial heating process, when the temperature detected by the temperature sensor that detects the water temperature is 88 degrees or less, the heater is continuously turned on, and when the temperature exceeds 90 degrees, the heater is turned off.

  The time required to rise to a predetermined temperature varies depending on the initial water temperature, etc., but the first process ensures a predetermined time for the initial heat treatment, and in this example, it is set to 7 minutes as a whole. Has been. In this example, the heater is turned on when the detected temperature of the sensor for detecting the water temperature is 88 degrees or less, and the heater is turned off when the detected temperature exceeds 90 degrees due to the continuous operation time of the heater ON. It is the same as the initial heat treatment of “Okayu”. Similarly, the heater is preferably controlled within 85 to 95 degrees, more preferably 88 to 92 degrees, and the entire time of the first process is preferably about 6 minutes 30 seconds to 7 minutes 30 seconds. Thus, this is also similar to "boiled / boiled", but continuous heater does not mean that it must be continuous throughout the entire first process (7 minutes in this example). In order to enable cooking while shortening the overall processing time as much as possible, in the initial heating, the heater is turned on substantially continuously to increase the water temperature. If the simmering process is possible, the heater may be turned off for some time.

When the initial heat treatment is finished, the process proceeds to the second phase, which is a process for full-fledged boiled heat treatment. In this face, the cutter assembly 95 stirs and simmers the food material finely, and includes intermittent motor operation.
The “boiled food / rice porridge” differs from the second process in several ways.

  Similar to “boiled food / boiled rice cake”, it is common in that a stew process in which heating by a heater is performed before the intermittent operation of the motor is added as a sub-process in the second process, but the difference is more preferable. By doing more intermittent operation. Specifically, the heater intermittent operation of 5 seconds ON / 5 seconds OFF is performed 23 times, and the heater intermittent operation of 3 minutes and 50 seconds is performed as a total time. However, if the water temperature exceeds 95 degrees during that time, the intermittent operation is not performed, and the intermittent operation of the heater is controlled so that the temperature can be maintained between 90 degrees and 95 degrees.

  After boiling and heating, the motor is intermittently operated and stirred while finely crushing the ingredients. At this time, the motor intermittent operation is carried out by rotating about 5 times ON / 10 seconds OFF at a rotational speed of 4500-5500 rpm with a relatively high rotation setting of 20 times, and as a potage in a relatively high temperature state. To provide smoothness.

  In the initial heat treatment in the first phase, since substantial stirring is not performed, there may be a temperature difference in the container. In addition, since there may be uneven temperature inside the food, the entire water temperature may be lowered by being pulverized and agitated by the intermittent operation of the motor described above. After the temperature is raised, no special heating is performed to prevent the container bottom from being burned by heating, and the temperature is gradually lowered.

In the simmering heating that is the second process, the heater is turned on for a maximum of 20 seconds, and when it exceeds 95 degrees during the ON, the heater is turned off.
After simmering and heating, the motor is intermittently rotated again to form a more fluid soup. For example, the motor rotation at this time is also set to a relatively high rotation speed of 4500-5500 rpm, 5 seconds ON / 10 seconds OFF 10 times, 20 seconds ON / 10 seconds OFF, and further 20 seconds After turning on, after 10 seconds of steaming time, the second process is terminated. Thus, the process is completed in about 20 minutes from the start of the first process to the end of the second process.

The intermittent operation for crushing and stirring by the motor is performed before and after the intermediate heating, but the intermittent operation of the motor may be continued and the heating process of the intermediate heating may be performed simultaneously in parallel therewith.
Until the heat retention process after the second process is started, the temperature usually does not reach 70 degrees or less, and therefore the ON / OFF control with the heater for maintaining the temperature is not performed. However, if the temperature reaches a lower limit of 70 degrees or less during the second process, the heater may be turned ON / OFF intermittently. In this case, for example, the upper limit of the temperature may be set to 75 degrees, and the intermittent operation of the heater may be controlled to be in the range of 75 degrees and 70 degrees.

  The third process, the next phase, has a heat retention process, and repeats intermittent operation by relatively low speed rotation of the motor speed setting of 400-600 rpm while the motor is ON for 5 seconds / 10 seconds OFF. However, temperature control is performed so that the range of 70 degrees and 75 degrees can be maintained. For example, in order to prevent scorching of the container, the heater is repeatedly operated intermittently at 2 seconds ON / 28 seconds OFF, and when the temperature reaches 75 ° C. or more, the heater is turned OFF and the lower limit of the temperature is set. The temperature is maintained so that the temperature can be maintained within a range of 70 degrees and an upper limit of 75 degrees.

(Machining profile of “Source / Jam”)
An example of the processing process of “source / jam” is shown in FIG.
By combining two different processes into one operation button 36, an operation button 36 for performing this new process is provided.

  In “sauce / jam”, stirring is performed to mix the ingredients strongly before substantial heating by the heater. For example, the setting during ON starts from a process of crushing and stirring the cutter assembly 95 by performing intermittent operation of the motor at a relatively high rotation of 4500 to 5500 rpm.

  For example, the motor does not turn on for a while after repeating the setting of 0.4 second ON / 0.8 second OFF six times. When the initial intermittent operation of the motor is completed, the heater is turned on for the initial preliminary heating to raise the water temperature in the container. In order to heat slowly, ON of the heater at this time is preferably intermittent operation. For example, 2 seconds ON / 4 seconds OFF is 30 times, and a total time of 3 minutes is secured. If the temperature exceeds 95 degrees by the sensor before 3 minutes elapses, the heater is turned off and the heater is turned off so that the temperature is as constant as possible, for example, a temperature in the range of 90 degrees to 95 degrees. Control intermittent operation. While the heater is being operated in the initial preheating, it is preferable that the motor is OFF. However, the motor and heater may be operated simultaneously. When this first process is completed, the second process is a phase of boiled heat treatment.

  The “sauce / jam” stewed heat treatment is a heat treatment and a stirring treatment that heats the sauce more slowly than “boiled food / rice porridge” or “potage”. For example, the heater is turned on for 3 seconds and turned off for 3 seconds 250 times, for a total of 25 minutes. However, if the water temperature exceeds 95 degrees during this time, the heater is not turned on and maintained at a constant temperature as much as possible, for example, the intermittent operation of the heater is controlled to be in the range of 95 degrees to 90 degrees.

  In this second process, while performing the boiled heating, the motor is operated at a relatively low speed, for example, the ON setting is intermittent operation of 2 seconds ON / 13 seconds OFF at a speed of 400 to 600 rpm, By agitating with slight crushing at the same time, the whole is slowly heated and finely mixed, but can be mixed to create a sense of touch as a sauce or jam. Moreover, this intermittent ON of the motor also provides the effect of making the temperature in the container uniform, and can prevent the occurrence of scorching.

When the boiling process for 25 minutes is completed, the second process is completed after a steaming time of 10 seconds, and the processing of “sauce / jam” for about 28 and a half minutes is completed.
Incidentally, when the operation button 36 is first pressed, a waiting time of about 10 seconds is provided until the motor operates so that the motor immediately operates and no noise is generated due to high rotation. This means that if you press a button that is different from the intended cooking menu due to an erroneous operation during this waiting time, you can reset it by pressing the same button again, and you can select the cooking menu again. Moreover, it is also for ergonomic considerations, and it is possible to avoid being surprised by the sudden sound generated by the elderly. During this waiting time, a sound message such as “processing starts” or “processing is canceled” at resetting may be output. Since the “soy milk” in the operation button 36 is also started from the operation of the motor, a standby time similar to that provided in “source / jam” may be provided.

(Processing of “soy milk”)
The basic operation profile for processing soymilk is not fundamentally different from that already described, but more specific processing will be described with reference to FIG. 10 again.
When the soy milk operation button 36 is pressed, the motor rotates at a relatively high rotational speed in order to grind soybean as an initial process. Thereafter, the food is pulverized by rotating the motor at a relatively low speed, and the simmering process is performed by controlling the heating with a heater for a certain period of time.

  More specifically, the rotation speed of the motor for the first crushing is set at 4500-5500 rpm at the time of ON and is performed at a relatively high speed rotation, for example, intermittent operation of 5 seconds ON / 5 seconds OFF. Repeat 15 times. Further, at the end of the initial process, ON is continued for about 30 seconds to perform fine grinding, and then the process proceeds to the next process.

  When the crushing is completed and the next process is started, the rotation of the stirring motor 11 is lowered while the temperature is gradually increased, and the continuous operation is performed. For example, while the motor is continuously rotated at a relatively low speed of about 500 rpm, the heater is turned on at the same time and the heater is turned on for 2 seconds / 4 seconds off for about 165 times, and the simmering heating while stirring is performed. I do. When the temperature is detected to be 90 degrees or more, the heater is turned off, and the heater is controlled while monitoring the temperature so that the temperature is maintained at or below 90 degrees. The low-speed continuous operation can prevent soy milk from coagulating and scorching. When this process is performed for a predetermined time, for example, 16 minutes and 30 seconds, the soy milk is almost finished. Then, the steaming operation for 10 seconds is performed and the motor is turned off. At this time, the soy milk is completed in about 20 minutes from the first operation to the completion of the soy milk. Then move on to the next stage.

  When the soy milk is completed, the temperature is gradually lowered for the heat retention, and then the process proceeds to the introduction process of the heat retention process for performing a certain temperature maintenance management. The heater is turned off while the motor is operated at a relatively low speed for a certain period of time so as not to cause blown-out due to partial temperature rise due to soy milk scorching or residual heat. For example, the heater is completely stopped until the temperature becomes 70 degrees or less while continuing the intermittent operation in which the motor is turned ON for 9 seconds / OFF for 1 second from the heat insulation introduction process to the full-scale heat insulation process. Furthermore, as a full-scale heat retention process, when it is detected that 70 degrees has been cut off, the heater is turned on and off by controlling the intermittent operation with a temperature setting of 75 degrees upper limit and 70 degrees lower limit to keep the temperature constant. The temperature is maintained in the vicinity of 70 degrees while repeating the stirring by the motor at the rotational speed of the speed. This heat retention process including the heat retention introduction process is set to operate for a total of about 30 minutes.

  For example, before the end of the operation for about 30 minutes, the heater is programmed to perform intermittent operation of ON for 2 seconds / OFF for 28 seconds about 60 times. If it seems to exceed, do not turn on the heater. In this way, when the ON operation and the operation period are set in advance by the program and the value from the actual temperature sensor is equal to or higher than the predetermined upper limit temperature during the ON time, the lower limit predetermined operation is performed. By programming to stop the ON operation until the temperature falls below the temperature, the temperature can be prevented from rising unnecessarily. Such a program setting is used not only for heat retention but also in other heating processes, and can enable efficient temperature control and management.

  In addition, in the intermittent operation of the heater and the motor, for example, it is turned off when the temperature is higher than a certain temperature, and is turned on when the temperature is lower than a certain temperature. As described above, it is possible to include any meaning of intermittent operation in which an ON and OFF set (set) is provided and the operation by the set is turned ON, either of which can be adopted, or a combination thereof can be adopted. However, as explained above, the ON / OFF set and the control that repeats it more than once are more detailed by preventing the occurrence of scorching and the temperature rise of the food during crushing, and preventing the extreme temperature rise. Various effects such as smooth temperature control and uniform crushing as a whole prevent quality deterioration and consequently have a positive effect on the taste after processing. Therefore, for intermittent operation, when the temperature is lower than a certain temperature, ON / OFF is performed once or more to increase the temperature, and when the temperature is higher than a certain temperature, the ON / OFF operation is stopped and turned OFF. The intermittent operation of control is more preferable. The ON and OFF interval times in this intermittent operation may be the same or different as already described in the embodiment, and the ON and OFF interval times are made different according to the passage of time. Also good.
