Description

  The present disclosure relates to a cooker.

  2. Description of the Related Art A cooking device is known in which a processing member such as a cutter is rotated by a motor to process a food material charged in a container (see, for example, Patent Document 1). In the cooking device described in Patent Document 1, the output shaft of the motor and the processing member in the container are connected via a power transmission mechanism, and the motor torque is transmitted to the processing member when the motor is energized. Usually, this type of motor is provided with an overcurrent detection circuit in order to protect the motor from overcurrent accompanying an increase in machining load. In the overcurrent detection circuit, the current value of the motor is monitored, and when an overcurrent is detected, it is determined that the motor is abnormal and the drive of the motor is stopped.

International Publication No. 2014/053011

  However, although the cooker described in Patent Document 1 can protect the motor from overcurrent, troubles caused by a decrease in the output of the motor cannot be avoided.

  This indication is made in view of this point, and makes it one of the objectives to provide the cooking device which can detect the motor abnormality by the output fall and can avoid an unexpected trouble.

  A cooker according to an aspect of the present disclosure is a cooker that processes a food charged in a container to a predetermined particle size by using a processing member, and detects a motor that rotates the processing member and a current value that flows through the motor. A current detector; and a control unit that determines motor abnormality based on the current value of the motor, wherein the control unit determines that the motor is abnormal when the current value of the motor is equal to or less than a predetermined threshold value indicating current shortage. It is characterized by doing.

  According to the present disclosure, when the current for the motor is insufficient, it is determined that the motor is abnormal. Therefore, the cooking operation can be stopped before the motor whose output is reduced is moved. Therefore, it is possible to avoid unexpected troubles such as the motor stopping during the cooking operation, and to keep the motor moving stably.

  Hereinafter, the cooking device of this Embodiment is demonstrated. FIG. 1 is an external perspective view of a cooking device in which a bottle according to the present embodiment is set. FIG. 2 is an external perspective view of the cooking device with the bottle of the present embodiment removed. In addition, although the cooking device of this Embodiment is a structure which can set a multiple types of bottle, in FIG.1 and FIG.2, it illustrates and demonstrates the bottle for pressure reduction. In the following description, a mixer is illustrated as an example of a cooker. However, any cooker that processes food by driving a motor may be used. For example, the technology of the present disclosure can be applied to a food processor and a slicer. is there.

  As shown in FIG. 1, the cooking device 1 is configured to finely process the food material to a predetermined particle size by the processing member 74 (see FIG. 4) after decompressing the inside of the decompression bottle 70 into which the food material has been charged. . A mounting table for the decompression bottle 70 is a cooker body 10, and a processing motor 41 (see FIG. 4), a control board, and the like are accommodated in the case of the cooker body 10. The front surface of the case of the cooker body 10 protrudes forward in a mountain shape, and an operation panel 11 is provided on the slope of the front surface of the case. The operation panel 11 is provided with indicator lamps for operation modes and errors, and various switches used for mode change and manual operation.

  A semi-cylindrical side pole 20 is erected next to the cooker main body 10, and a vacuum pump 42 for decompression (see FIG. 4), piping, wiring and the like are accommodated in the case of the side pole 20. Yes. An illumination bar 21 is provided in front of the side pole 20, and the illumination bar 21 displays the decompression state of the decompression bottle 70 in stages. An arm 30 connected to the bottle cap 72 of the decompression bottle 70 is supported on the upper side of the side pole 20 so as to be swingable in the vertical direction. On the distal end side of the arm 30, a contact head 31 having a circular shape when viewed from above is formed in airtight contact with the upper surface of the bottle cap 72.

  When the decompression bottle 70 is set in the cooking device body 10, the processing member 74 provided on the bottle base 73 is connected to the motor 41 of the cooking device body 10. Although not shown in detail, the coupling provided on the rotating shaft of the machining member 74 and the coupling provided on the output shaft of the motor 41 are engaged and mechanically connected. When the arm 30 is connected to the bottle cap 72 of the decompression bottle 70, the decompression bottle 70 is connected to the vacuum pump 42 through the intake passage in the case of the arm 30 and the side pole 20. Thus, in the cooking device 1, a processing mechanism is configured by the motor 41, the processing member 74, and the power transmission mechanism, and a decompression mechanism is configured by the vacuum pump 42 and the intake passage.

  As shown in FIG. 2, the cooking device 1 makes the decompression bottle 70 detachable with respect to the cooking device body 10 by lifting the arm 30 directly above. A concave portion 23 that is recessed along the outer shape of the arm 30 is formed on the side surface 22 of the semi-cylindrical side pole 20 on the cooker body 10 side. For this reason, when the arm 30 is lowered directly, the entire arm 30 is completely accommodated in the recess 23, and the arm 30 does not become an obstacle when the bottle is replaced. The lower part 24 of the recess 23 is cut out in an arc shape so as to leave a gap in a state where the arm 30 is accommodated, and the arm 30 can be pulled up from the recess 23 by placing a finger in the gap.

  An annular pad 32 is provided on the contact head 31 of the arm 30, and the annular pad 32 comes into airtight contact with the upper portion of the bottle cap 72 when the arm 30 is tilted horizontally. An inlet of the intake passage is opened inside the annular pad 32, and an outlet of the exhaust passage of the decompression bottle 70 is formed on the upper surface of the bottle cap 72. The exhaust path of the bottle cap 72 and the intake path of the arm 30 communicate with each other in an airtight manner by the annular pad 32, and air is drawn into the vacuum pump 42 in the side pole 20 from the decompression bottle 70. In the middle of the extending direction of the arm 30, a slit 33 is formed that escapes from the peripheral wall 75 of the bottle cap 72 when the arm 30 is tilted horizontally.

  On the upper surface of the cooker main body 10, a rectangular annular convex portion 12 that projects the bottom opening of the bottle base 73 of the decompression bottle 70 from the inside is projected. The annular protrusion 12 is formed along the opening edge of the bottle base 73, and the arcuate portions at the four corners of the annular protrusion 12 are raised so that the bottle base 73 can be easily guided. One side of the annular convex portion 12 is cut out, and a socket 13 for supplying electric power to the heating bottle 80 (see FIG. 5) is provided in the cutout portion. An opening 14 for coupling is formed inside the annular convex portion 12, and the output shaft of the motor 41 is connected to the processing member 74 by positioning the bottle base 73 on the annular convex portion 12.

  The cooking device 1 is used not only for the decompression bottle 70 but also for the heating bottle 80 and the storage bottle 90 (see FIG. 6). When the heating bottle 80 is used, the arm 30 is accommodated in the recess 23 of the side pole 20, and the heating bottle 80 is processed while heating the food without reducing the pressure. When the storage bottle 90 is used, the arm 30 is pulled out from the recess 23 of the side pole 20, and the inside of the storage bottle 90 is decompressed to maintain the freshness of the processed food product for a long time. Thus, it can be used for various purposes by exchanging the bottle of the cooking device 1. Details of each bottle will be described later.

  By the way, as shown to FIG. 3A, in the general cooking appliance 94, in order to protect the motor 95 from overcurrent, the overcurrent detection circuit 96 is provided. The overcurrent detection circuit 96 monitors the inrush current at the start of the motor and the current during motor driving, and stops the motor 95 when the current value of the motor 95 exceeds the rated current value. The overcurrent detection circuit 96 can detect an overcurrent due to a short circuit or an overload, but cannot detect a shortage of current due to motor malfunction. For this reason, even if current shortage has occurred in the motor 95, the motor 95 may be moved to cause a trouble during the cooking operation.

  For example, as shown in FIG. 3B, since the motor 95 moves even immediately before the product lifetime, the processing member 99 is rotationally driven by the motor 95 after the bottle 98 is decompressed by the vacuum pump 97. However, since the output (torque) of the motor 95 is reduced due to current shortage, the motor 95 cannot withstand the processing load during the processing operation of the food, and the motor 95 generates heat and stops during the cooking operation. There is a fear. If the motor 95 is stopped in a state where the cooking operation is not completed, there is a problem that the ingredients put into the bottle 98 are wasted. In addition, various mechanisms other than the motor 95 such as the vacuum pump 97 have been driven despite the motor malfunction.

  Therefore, in the cooking device 1 of the present embodiment, paying attention to a problem peculiar to the cooking device 1 that the food is wasted when the motor 41 stops in the middle of the cooking operation, the motor 41 detects a current shortage of the motor 41 and detects a motor abnormality. Judgment. Thereby, when it is determined that the motor is abnormal, the cooking operation is not started in a situation where appropriate cooking cannot be expected due to the motor abnormality, and it is possible to prevent the food from being wasted due to incomplete cooking. In addition, by prohibiting not only the motor 41 but also various mechanisms such as the vacuum pump 42 other than the motor 41, a series of cooking operations on the food by the cooking device 1 can be stopped.

  Hereinafter, with reference to FIGS. 4 to 7, a detailed configuration of the cooking device of the present embodiment will be described. FIG. 4 is a schematic front view of a cooking device in which the decompression bottle of the present embodiment is set. FIG. 5 is a schematic front view of a cooking device in which the heating bottle of the present embodiment is set. FIG. 6 is a schematic front view of a cooking device in which the storage bottle of the present embodiment is set. FIG. 7 is a front view of the operation panel of the present embodiment. 4 to 7 are only examples, and can be changed as appropriate.

  As shown in FIG. 4, the cooking device 1 is provided with first to third detection units 43, 44, 45 in order to determine the type of bottle. The 1st detection part 43 is comprised by the Hall element, for example, and is installed inside the case in the vicinity of the upper surface of the cooker main body 10 in consideration of waterproofness. The second detection unit 44 is configured by, for example, a mechanical switch, and is installed in the slit 33 of the arm 30. The third detection unit 45 is configured by, for example, a Hall element, and is located at a position facing the bottle cap 82 of the heating bottle 80 when the arm 30 is accommodated in the recess 23 (see FIG. 2) of the side pole 20. It is installed (see FIG. 5).

  The detection results of the first to third detection units 43, 44, and 45 are output to a determination circuit (not shown), and the type of the bottle is determined by the determination circuit based on a combination of these detection results. As described above, the first to third detection units 43, 44, and 45 and the determination circuit constitute a determination unit that determines the type of the bottle. In the cooking device 1, the function can be limited according to the type of the bottle by determining the type of the bottle. Depending on the type of the bottle, the heat treatment or the decompression process is prohibited, and for example, it is possible to prevent the cooking by mistake for the non-heating decompression bottle 70.

  A capacitance sensor 47 for detecting foreign matter is installed in the contact head 31 of the arm 30, and foreign matter such as water and food in the contact head 31 is detected from the change in capacitance. When an abnormality is detected by the capacitance sensor 47, the driving of the vacuum pump 42 is stopped. A pressure sensor 51 for detecting the pressure in the bottle is installed in the middle of the intake passage 49 in the side pole 20, and foreign matter such as water and food in the intake passage 49 is detected from the change in pressure. When an abnormality is detected by the pressure sensor 51, the driving of the vacuum pump 42 is stopped. Further, an air release valve 52 is installed in the middle of the intake passage 49, and the intake passage 49 is returned to atmospheric pressure by opening the air release valve 52.

  As described above, the motor 41 that rotationally drives the processing member 74 is installed in the case of the cooker body 10, and the current detector 55 that detects the current value is connected to the motor 41. The current detector 55 is connected to a control unit 56 that determines motor abnormality based on the value of current flowing through the motor 41. The control unit 56 is provided with a first determination circuit 57 that determines an overcurrent of the motor 41 as a motor abnormality, and a second determination circuit 58 that determines an insufficient current of the motor 41 as a motor abnormality. The first and second determination circuits 57 and 58 determine that the current is excessive or insufficient for the motor 41 as a motor abnormality.

  The first determination circuit 57 compares the current value of the motor 41 with a predetermined threshold value (rated current value) indicating an overcurrent, and determines that the motor is abnormal due to an overcurrent when the current value of the motor 41 exceeds a predetermined threshold value. Is done. The second determination circuit 58 compares the current value of the motor 41 with a predetermined threshold value indicating current shortage. When the current value of the motor 41 falls below the predetermined threshold value, it is determined that the motor is abnormal due to current shortage. In the case of motor abnormality, a flag indicating motor abnormality is set in the memory, and by referring to the flag at the driving timing of the cooking device 1, the control unit 56 prohibits driving of each part of the cooking device 1 and a series of cooking. The operation is stopped.

  In addition, the control unit 56 performs overall control of the entire cooking device 1 as well as determination of motor abnormality. The control unit 56 includes a processor that executes various processes, a memory, and the like. The memory is composed of one or a plurality of storage media such as a ROM (Read Only Memory) and a RAM (Random Access Memory) depending on the application. In addition to the control program for the cooker 1, the memory stores an operation program corresponding to the operation mode, various parameters, and the like. In addition, the cooking device 1 is provided with an antenna and a transmission / reception circuit so that wireless communication with the tablet terminal is possible.

  The decompression bottle 70 has a bottle cap 72 attached to the top of a bottle body 71 made of Tritan (registered trademark) and a bottle base 73 attached to the bottom of the bottle body 71. An exhaust path is formed in the bottle cap 72, and a check valve for preventing backflow into the bottle is provided in the middle of the exhaust path. A peripheral wall 75 is formed on the outer edge of the bottle cap 72, and the second detection unit 44 is pushed in by the peripheral wall 75 entering the slit 33 of the arm 30. A processing member 74 is rotatably supported on the bottle base 73, and a magnet 76 to be detected by the first detection unit 43 is provided.

  When the decompression bottle 70 is used, the decompression bottle 70 is installed on the cooker body 10, and the abutment head 31 of the arm 30 is abutted against the bottle cap 72. As a result, the magnet 76 of the bottle base 73 faces the first detection unit 43 of the cooker body 10, and the peripheral wall 75 of the bottle cap 72 enters the slit 33 of the arm 30. The first detection unit 43 detects the magnet 76 of the bottle base 73, and the second detection unit 44 detects the peripheral wall 75 of the bottle cap 72. When the first and second detection units 43 and 44 are turned on and the third detection unit 45 is turned off, the decompression bottle 70 is detected.

  The control unit 56 refers to the flag in the memory before starting the operation, and confirms whether or not the flag indicating motor abnormality is set. If the flag is set in the memory, the controller 56 determines that the motor is abnormal and the driving of the vacuum pump 42 is prohibited. As described above, when the current to the motor 41 is insufficient, the pressure reduction operation before the machining operation by the motor 41 is stopped. Therefore, the vacuum pump 42 is not driven in a situation in which proper cooking cannot be expected due to a decrease in the output of the motor 41, and it is possible to prevent food from being wasted due to incomplete cooking.

  When the flag is not set in the memory, the operation is started, and the vacuum bottle 70 is decompressed by the vacuum pump 42. At this time, the decompression state of the decompression bottle 70 is displayed on the illumination bar 21 of the side pole 20. When the vacuum pump 42 is stopped and the decompression of the decompression bottle 70 is completed, the motor 41 is driven and the processing member 74 is rotated to process the food. By processing the food in a reduced pressure state, the food can be processed to a uniform particle size while suppressing a decrease in nutrients due to oxidation of the food, and the freshness of the processed food can be maintained for a long time.

  As shown in FIG. 5, the heating bottle 80 has a bottle cap 82 attached to the top of a glass bottle main body 81 and a bottle base 83 attached to the bottom of the bottle main body 81. A magnet 85 to be detected by the third detection unit 45 is provided on the outer peripheral edge of the bottle cap 82. A processing member 84 is rotatably supported on the bottle base 83, and a magnet 86 that is a detection target of the first detection unit 43 is provided. The bottom of the heating bottle 80 is formed of a heat conductive material, and a heater 87 that heats food in the heating bottle 80 and the temperature in the heating bottle 80 are detected inside the bottle base 83. A temperature sensor 88 is provided.

  When the heating bottle 80 is used, the heating bottle 80 is installed on the cooker body 10 in a state where the arm 30 is accommodated in the recess 23 (see FIG. 2) of the side pole 20. Thereby, the magnet 86 of the bottle base 83 faces the first detection unit 43 of the cooker body 10, and the magnet 85 on the outer periphery of the bottle cap 82 faces the third detection unit 45 of the arm 30. The first detection unit 43 detects the magnet 86 of the bottle base 83 and the third detection unit 45 detects the magnet 85 of the bottle cap 82. The heating bottle 80 is detected when the first and third detection units 43 and 45 are turned on and the second detection unit 44 is turned off.

  The control unit 56 refers to the flag in the memory before starting the operation, and confirms whether or not the flag indicating motor abnormality is set. If the flag is set in the memory, the controller 56 determines that the motor is abnormal and the heater 87 is inhibited from being driven. As described above, when the current to the motor 41 is insufficient, the heating operation before the machining operation by the motor 41 is stopped. Therefore, the heater 87 is not driven in a situation in which proper cooking cannot be expected due to a decrease in the output of the motor 41, and it is possible to prevent food from being wasted due to incomplete cooking.

  When the flag is not set in the memory, the operation is started, and the inside of the heating bottle 80 is heated by the heater 87. At this time, the plug of the heater 87 is inserted into the socket 13 (see FIG. 2) on the cooker body 10, and the heater 87 is energized from the cooker body 10. Further, the heating state of the heating bottle 80 is displayed on the illumination bar 21 of the side pole 20 as in the reduced pressure state. While being heated by the heater 87, the motor 41 is driven to process the food by the processing member 84. The temperature in the heating bottle 80 is detected by the temperature sensor 88, the heating of the heater 87 is controlled based on the temperature in the heating bottle 80, and the inside of the heating bottle 80 is maintained at a predetermined temperature.

  The heating bottle 80 is not used only for cooking. The heating bottle 80 is a container that can be used for cooking, but can also be used for non-heating cooking. For example, the heating bottle 80 may be used for cooking such as soup cooking in a soup mode described later, or may be used in a non-heated state as a coffee mill in a nut mode described later. Therefore, the heater 87 is not always driven when the heating bottle 80 is set. Therefore, in the heating mode such as the nut mode, the heating of the heater 87 is disabled regardless of whether or not the motor abnormality is determined, and only the driving of the motor 41 is prohibited.

  As shown in FIG. 6, the storage bottle 90 has a bottle cap 92 mounted on the top of a resin bottle main body 91. An attachment 93 for raising the bottom is detachably attached to the bottom of the storage bottle 90. When the storage bottle 90 is used, the storage bottle 90 is installed on the cooker body 10 via the attachment 93, and the contact head 31 of the arm 30 contacts the bottle cap 92. Since the storage bottle 90 is provided with neither a magnet nor a peripheral wall, when the storage bottle 90 is set, all of the first to third detection units 43, 44, and 45 are turned off. .

  Since the food is not processed in the storage bottle 90, it is not necessary to drive the motor 41 when the storage bottle 90 is set. Even if a motor abnormality occurs, the food is not wasted, so the vacuum pump 42 may be driven to start the pressure reducing operation. Since the motor 41 is not moved, the decompression operation may be allowed without performing the motor abnormality determination process. As described above, the storage bottle 90 that is not driven by the motor 41 does not require the motor abnormality determination process. Therefore, even if the motor abnormality determination process is performed using the detection of the decompression bottle 70 and the heating bottle 80 as a trigger. Good.

  In addition, the cooking device 1 is provided with a warning unit 59 that warns the motor abnormality when the controller 56 determines that the motor is abnormal. Thereby, it is possible to inform the user of the motor abnormality and stop cooking the food. The warning unit 59 may be configured to be able to warn the user of motor abnormality, and may warn by, for example, a buzzer warning, a voice warning, a light emission warning, a display warning, or a combination thereof. In addition, when the cooking device 1 is wirelessly connected to the user's portable terminal, a warning signal of motor abnormality may be transmitted from the cooking device 1 to the portable terminal to prompt the user to stop cooking.

  As shown in FIG. 7, the operation panel 11 is provided with operation mode lamps 61a-61g, error lamps 62a-62d, a time adjustment lamp 63, and a speed adjustment lamp 64. The operation mode lamps 61a to 61g indicate a soy milk mode, a soup mode, a paste mode, a nut mode, a smoothie mode, a frozen mode, and a manual mode from the left in the drawing. Error lamps 62a to 62d indicate a mounting error, a pressure error, an excessive food error, and a temperature error from the left in the drawing. The time adjustment lamp 63 indicates a time adjustment mode, and the speed adjustment lamp 64 indicates a speed adjustment mode.

  The operation panel 11 is provided with a segment display 65, a dial switch 66, and push switches 67a-67c. The segment display 65 counts down the processing time for vacuum cooking. The dial switch 66 is used not only for switching the operation mode but also for adjusting the operation time and speed. Push switches 67a to 67c indicate a flash switch, a start switch, and a release switch from the left in the figure. The flash switch performs a stirring operation only during pressing, the start switch starts various operations by pressing, and the release switch performs vacuum release.

  By turning the dial switch 66 on the operation panel 11, the operation mode lamps 61a to 61g are turned on in order and the operation mode is selected. At this time, selectable operation modes are limited according to the type of the bottle. For example, in the case of the decompression bottle 70, when the dial switch 66 is turned, it is lit in order only between the operation mode lamps 61e-61g, and the operation mode for heating cannot be selected. In the case of the heating bottle 80, when the dial switch 66 is turned, it is lit in order only between the operation mode lamps 61a to 61d, and the operation mode for pressure reduction cannot be selected.

  In the present embodiment, the decompression operation mode can be selected when the decompression bottle 70 is set, and the heating operation mode can be selected when the heating bottle 80 is set. . Since the heating operation mode cannot be selected when the decompression bottle 70 is set, the decompression bottle 70 not corresponding to the heating operation mode is not erroneously heated. Further, when the heating bottle 80 is set, the depressurization operation mode cannot be selected, so that the heating bottle 80 not corresponding to the depressurization operation mode is not depressurized by mistake. Thus, the operation mode is limited so that a cooking operation suitable for the type of bottle is selected.

  Then, with reference to FIG. 8, the processing operation by a cooking appliance is demonstrated. FIG. 8 is a diagram showing a flowchart of the machining operation of the present embodiment. Note that the flowchart of FIG. 8 shows an example of the machining operation, and is not limited to this. For example, a part of the processing order may be changed. Further, in FIG. 8, for convenience of explanation, description will be made using the reference numerals in FIG. 4.

  As shown in FIG. 8, when the cooking device 1 is turned on, the type of the bottle set in the cooking device 1 is detected (step S01). When the first and second detection units 43 and 44 are ON and the third detection unit 45 is OFF, the decompression bottle 70 is detected, and the first and third detection units 43 and 45 are ON and the second detection unit 45 is ON. When the detection unit 44 is OFF, the heating bottle 80 is detected. Thereby, the operation mode according to the kind of bottle can be selected. When the storage bottle 90 is set in the cooking device 1, all of the first to third detection units 43-45 are turned off, as in the case where no bottle is set in the cooking device 1. It has become.

  Next, when the type of the bottle is detected by the cooking device 1, a motor abnormality determination process is performed by the control unit 56 (step S02). In this case, it is confirmed whether or not a flag indicating motor abnormality is set in the memory. If the flag is set in the memory, it is determined that the motor is abnormal (Yes in step S02), and the warning unit 59 warns the user of the motor abnormality (step S03). Moreover, a process transfers to step S11, without starting cooking operation, and a series of cooking operation by the cooking appliance 1 is prohibited. Thereby, a foodstuff is not wasted by the incomplete cooking by motor abnormality.

  On the other hand, when the flag is not set in the memory, it is determined that the motor is normal (No in step S02), and the cooking operation corresponding to the type of the bottle is started (step S04). When the depressurizing bottle 70 is detected, a depressurizing operation by the depressurizing mechanism is performed, and when the heating bottle 80 is detected, the heating operation by the heater 87 is performed. Next, when the decompression operation or the heating operation is completed, the machining member 74 is rotationally driven by the motor 41 and the machining operation is started (step S05). Thereby, the foodstuff is gradually finely pulverized by the rotation of the processing member 74.

  Next, when the machining operation by the motor 41 is started, the current value 55 flowing through the motor 41 is detected by the current detector 55 (step S06). The current value I of the motor 41 detected by the current detector 55 is output to the control unit 56. Next, in the controller 56, the first determination circuit 57 determines whether or not the current value I of the motor 41 is equal to or greater than a predetermined threshold value T1 indicating the rated current value (step S07). If the current value I of the motor 41 is greater than or equal to the predetermined threshold T1 (Yes in step S07), the controller 56 determines that the motor is abnormal due to overcurrent, sets a flag indicating motor abnormality in the memory, and stops the motor 41. (Step S09).

  On the other hand, when the current value I of the motor 41 is smaller than the predetermined threshold value T1 (No in step S07), the second determination circuit 58 determines whether or not the current value I of the motor 41 is equal to or lower than the predetermined threshold value T2 indicating current shortage. Is determined (step S08). If the current value I of the motor 41 is less than or equal to the predetermined threshold T2 (Yes in step S08), the controller 56 determines that the motor is abnormal due to insufficient current, sets a flag indicating motor abnormality in the memory, and stops the motor 41. (Step S09). In the current shortage determination, the current value I of the motor 41 is compared with the threshold value T2 while avoiding immediately after the start of machining and immediately before the end of the operation so that a motor abnormality is not detected at the rise and fall of the motor 41.

  Next, it is determined whether or not the machining operation is finished (step S10), and the processes from step S06 to step S08 are repeated until the machining operation is finished. When the processing operation ends, it is determined whether or not the cooker 1 is turned off (step S11). If the cooker 1 is not turned off (No in step S11), the process starts from step S01. The If it is determined that the motor is abnormal due to the current detection during the processing operation in the current cooking operation, the flag indicating the motor abnormality is set in the memory. Therefore, the next cooking operation is preceded by the processing operation by the motor 41. Cooking operation is prohibited.

  As described above, in the cooking device 1 of the present embodiment, when the current to the motor 41 is insufficient, it is determined that the motor is abnormal. Therefore, the cooking operation can be stopped before moving the motor 41 whose output has decreased. . Therefore, unexpected troubles such as the motor 41 stopping during the cooking operation can be avoided, and the motor 41 can be moved stably.

A determination may be made.

  Moreover, in above-mentioned embodiment, although it was set as the structure by which a foodstuff is processed with a process member after the inside of a bottle is pressure-reduced or heated with a cooking device, it is not limited to this structure. The food material may be processed without reducing or heating the inside of the bottle by the cooker. Therefore, the cooking device does not need to be provided with a decompression mechanism and a heater.

  Further, in the above-described embodiment, when the controller determines that the motor is abnormal, the decompression operation and the heating operation are prohibited. However, the present invention is not limited to this configuration.

  In the above-described embodiment, the configuration in which the type of the bottle is determined by the determination circuit based on the detection result of the first to third detection switches is illustrated as the determination unit. However, the present invention is not limited to this configuration. The determination unit may be configured to be able to determine at least the decompression bottle. For example, the determination unit may be configured to determine with a determination circuit based on the detection result of a single detection switch.

  In the above-described embodiment, the type of the bottle is discriminated by the discriminating unit, but the present invention is not limited to this configuration. The cooking unit may not be provided with a determination unit, and the food may be processed without the type of the bottle being determined by the cooking device.

  Moreover, although this Embodiment and the modified example were demonstrated, what combined the said embodiment and modified example entirely or partially as another embodiment may be sufficient.

  The technology of the present disclosure is not limited to the above-described embodiments and modifications, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea.
