Description

The present disclosure relates to cookers.

2. Description of the Related Art As a cooking device, there is known a cooking device in which a processing member such as a cutter is rotated by a motor to process food put into a container (see, for example, Patent Document 1). In the cooker 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 motor torque is transmitted to the processing member by energizing the motor. Usually, this type of motor is provided with an overcurrent detection circuit to protect the motor from overcurrent that accompanies an increase in machining load. The overcurrent detection circuit monitors the current value of the motor, and when an overcurrent is detected, it is determined that the motor is abnormal and the driving of the motor is stopped.

WO2014/054301

However, in the cooker disclosed in Patent Document 1, although the motor can be protected from overcurrent, it is not possible to avoid troubles caused by a decrease in the output of the motor.

The present disclosure has been made in view of the above points, and one of the objects thereof is to provide a cooker capable of detecting a motor abnormality due to a decrease in output and avoiding unforeseen troubles.

A cooker according to one aspect of the present disclosure is a cooker that processes foodstuff put into a container to a predetermined particle size by a processing member, and includes a decompression mechanism that decompresses the inside of the container, and a plurality of types of bottles of the container. a discriminating unit for discriminating that the decompression bottle is selected from the above; a motor for rotationally driving the processing member; a current detector for detecting a current value flowing through the motor ; and a control unit that determines that the motor is abnormal when the value is equal to or less than a predetermined threshold value, the control unit does not determine that the motor is abnormal, and the determination unit determines that the type of the container is the decompression bottle. In this case, the decompression mechanism is driven to reduce the pressure in the decompression bottle, and when the control unit determines that the motor is abnormal, the processing operation by the motor and the processing member and the decompression mechanism are performed. It is characterized in that decompression operation in the decompression bottle is prohibited .
A cooker according to one aspect of the present disclosure is a cooker that processes foodstuff put into a container to a predetermined particle size by a processing member, and includes a heater that heats the inside of the container, and a plurality of types of containers from bottles. A discriminating unit that discriminates the selected heating bottle, a motor that rotationally drives the processing member, a current detector that detects a current value flowing through the motor, and a current value of the motor that indicates current shortage. a control unit that determines that the motor is abnormal when the value is equal to or less than a predetermined threshold value, the control unit does not determine that the motor is abnormal, and the determination unit determines that the type of the container is the heating bottle. the heater is driven to heat the inside of the heating bottle, and when the controller determines that the motor is abnormal, the controller performs a processing operation by the motor and the processing member, and the heating by the heater. It is characterized by prohibiting the heating operation inside the bottle.

According to the present disclosure, since it is determined that the motor is abnormal when the current to the motor is insufficient, the cooking operation can be stopped before the motor whose output has decreased is operated. Therefore, it is possible to avoid unforeseen troubles such as the motor stopping in the middle of the cooking operation, and it is possible to keep the motor running stably.

The cooker according to this embodiment will be described below. FIG. 1 is an external perspective view of a cooker in which the bottle of this embodiment is set. FIG. 2 is an external perspective view of the cooker from which the bottle of this embodiment is removed. The cooker according to the present embodiment has a structure in which a plurality of types of bottles can be set, but FIG. 1 and FIG. In the following description, a mixer is used as an example of a cooker, but any cooker that processes foodstuffs by driving a motor may be used. For example, the technology of the present disclosure can also be applied to food processors and slicers. be.

As shown in FIG. 1, the cooker 1 is configured to reduce the pressure in a decompression bottle 70 into which foodstuffs are placed, and then finely process the foodstuffs to a predetermined particle size by a processing member 74 (see FIG. 4). . The table for decompression bottle 70 is cooker main body 10, and the case of cooker main body 10 accommodates motor 41 (see FIG. 4) for processing, a control board, and the like. The front of the case of the cooker main body 10 protrudes forward in a mountain shape, and an operation panel 11 is provided on the slope of the front of the case. The operation panel 11 is provided with display lamps for operation modes, errors, etc., and various switches used for mode changes and manual operations.

A semi-cylindrical side pole 20 is erected next to the cooker main body 10, and a vacuum pump 42 (see FIG. 4) for reducing pressure, piping, wiring, etc. are housed in the case of the side pole 20. there is 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 step by step. An arm 30 connected to the bottle cap 72 of the decompression bottle 70 is supported on the upper portion of the side pole 20 so as to be vertically swingable. A circular contact head 31 is formed on the tip side of the arm 30 and airtightly contacts the upper surface of the bottle cap 72 .

When the decompression bottle 70 is set in the cooker main body 10 , the processing member 74 provided on the bottle base 73 is connected to the motor 41 of the cooker main body 10 . Although not shown in detail, the coupling provided on the rotating shaft of the processing member 74 and the coupling provided on the output shaft of the motor 41 are meshed 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 cooker 1, the motor 41, the processing member 74, and the power transmission mechanism constitute a processing mechanism, and the vacuum pump 42 and the intake passage constitute a decompression mechanism.

As shown in FIG. 2, the cooker 1 allows the decompression bottle 70 to be attached to and detached from the cooker body 10 by lifting the arm 30 straight up. A side surface 22 of the semi-cylindrical side pole 20 on the cooker main body 10 side is formed with a concave portion 23 recessed along the outer shape of the arm 30 . Therefore, when the arm 30 is lowered straight down, the entire arm 30 is completely accommodated in the concave portion 23, and the arm 30 does not become an obstacle during bottle replacement. A lower part 24 of the recess 23 is notched in an arcuate shape so as to leave a gap with the arm 30 accommodated therein.

An annular pad 32 is provided on the contact head 31 of the arm 30 , and when the arm 30 is horizontally tilted, the annular pad 32 is brought into airtight contact with the upper portion of the bottle cap 72 . An inlet of an intake passage is opened inside the annular pad 32 , and an outlet of an 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 are airtightly connected by the annular pad 32 , and air is drawn from the decompression bottle 70 to the vacuum pump 42 in the side pole 20 . A slit 33 is formed in the middle of the extending direction of the arm 30 to escape from the peripheral wall 75 of the bottle cap 72 when the arm 30 is horizontally tilted.

A rectangular annular projection 12 for positioning the bottom opening of the bottle base 73 of the decompression bottle 70 from the inside protrudes from the upper surface of the cooker main body 10 . The annular projection 12 is formed along the edge of the opening of the bottle base 73 , and the circular arc-shaped portions at the four corners of the annular projection 12 are raised to facilitate guiding the bottle base 73 . One side of the annular projection 12 is notched, and the notched portion is provided with a socket 13 for supplying power to the heating bottle 80 (see FIG. 5). A coupling opening 14 is formed inside the annular projection 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 projection 12 .

This cooker 1 is also used for a heating bottle 80 and a storage bottle 90 (see FIG. 6) in addition to the decompression bottle 70 . When the heating bottle 80 is used, the arm 30 is accommodated in the recess 23 of the side pole 20, and the food is processed while being heated without decompressing the heating bottle 80. - 特許庁When the storage bottle 90 is used, the arms 30 are pulled out from the recesses 23 of the side poles 20 to reduce the pressure in the storage bottle 90 to maintain the freshness of processed ingredients for a long time. Thus, by exchanging the bottle of the cooker 1, it is possible to use it for various purposes. Details of each bottle will be described later.

By the way, as shown in FIG. 3A, a typical cooker 94 is provided with an overcurrent detection circuit 96 to protect the motor 95 from overcurrent. The overcurrent detection circuit 96 monitors the inrush current at motor startup 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 overcurrent due to short circuit or overload, but cannot detect current shortage due to motor malfunction. Therefore, even if the motor 95 is short of electric current, the motor 95 may be operated to cause trouble during the cooking operation.

For example, as shown in FIG. 3B, the motor 95 operates even just before the end of the life of the product. However, since the output (torque) of the motor 95 is reduced due to the shortage of current, the motor 95 cannot withstand the processing load during the food processing operation, and the motor 95 generates heat and stops during the cooking operation. There is a risk. If the motor 95 is stopped while the cooking operation is incomplete, 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, were driven in spite of the motor failure.

Therefore, in the cooker 1 of the present embodiment, attention is paid to the problem peculiar to the cooker 1 that food is wasted if the motor 41 stops in the middle of the cooking operation. Judging. As a result, when it is determined that the motor is abnormal, the cooking operation is not started in a situation where proper cooking cannot be expected due to the motor abnormality, and food is prevented from being wasted due to incomplete cooking. In addition, by prohibiting the driving of not only the motor 41 but also various mechanisms other than the motor 41, such as the vacuum pump 42, it is possible to stop the series of cooking operations for the foodstuff by the cooker 1. FIG.

The detailed configuration of the cooker according to the present embodiment will be described below with reference to FIGS. 4 to 7. FIG. FIG. 4 is a schematic front view of a cooker in which the decompression bottle of the present embodiment is set. FIG. 5 is a schematic front view of a cooker in which the heating bottle of the present embodiment is set. FIG. 6 is a schematic front view of a cooker in which the storage bottle of the present embodiment is set. FIG. 7 is a front view of the operation panel of this embodiment. It should be noted that FIGS. 4 to 7 are only examples, and can be changed as appropriate.

As shown in FIG. 4, the cooker 1 is provided with first to third detectors 43, 44, and 45 for determining the type of bottle. The first detection unit 43 is composed of, for example, a Hall element, and is installed inside the case near the upper surface of the cooker main body 10 in consideration of waterproofness. The second detection section 44 is composed of, for example, a mechanical switch and is installed in the slit 33 of the arm 30 . The third detection unit 45 is composed of, 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. installed (see Figure 5).

The detection results of the first to third detectors 43, 44 and 45 are output to a discrimination circuit (not shown), and the combination of these detection results allows the discrimination circuit to discriminate the type of bottle. Thus, the first to third detectors 43, 44, 45 and the discrimination circuit constitute a discrimination section for discriminating the type of bottle. In the cooker 1, by discriminating the type of the bottle, it is possible to limit the functions according to the type of the bottle. Heating processing and decompression processing are prohibited according to the type of the bottle, and for example, erroneous cooking with heat on the non-heating decompression bottle 70 is prevented.

A capacitance sensor 47 for foreign matter detection 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 changes in capacitance. When the capacitance sensor 47 detects an abnormality, the vacuum pump 42 is stopped. A pressure sensor 51 for detecting the pressure inside the bottle is installed in the middle of the intake passage 49 in the side pole 20, and foreign substances such as water and foodstuffs in the intake passage 49 are detected from changes in the pressure. When the pressure sensor 51 detects an abnormality, the vacuum pump 42 is stopped. An air release valve 52 is installed in the middle of the air intake path 49, and the air intake path 49 is returned to the atmospheric pressure by opening the air release valve 52. As shown in FIG.

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

The first determination circuit 57 compares the current value of the motor 41 with a predetermined threshold (rated current value) indicating overcurrent, and determines that the motor is abnormal due to overcurrent when the current value of the motor 41 exceeds the predetermined threshold. be done. In the second determination circuit 58, the current value of the motor 41 is compared with a predetermined threshold value indicating insufficient current, and when the current value of the motor 41 is equal to or less than the predetermined threshold value, it is determined that the motor is abnormal due to insufficient current. In the case of a motor abnormality, a flag indicating the motor abnormality is set in the memory, and by referring to the flag at the driving timing of the cooking appliance 1, the control unit 56 prohibits the driving of each part of the cooking appliance 1, thereby performing a series of cooking. Operation is aborted.

In addition, the control unit 56 not only determines whether the motor is abnormal, but also controls the cooking appliance 1 as a whole. The control unit 56 is composed of a processor, a memory, and the like that execute various processes. The memory is composed of one or more storage media such as ROM (Read Only Memory), RAM (Random Access Memory), etc., 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 cooker 1 is provided with an antenna and a transmission/reception circuit so as to be able to wirelessly communicate with the tablet terminal.

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 is provided in the middle of the exhaust path to prevent backflow into the bottle. A peripheral wall 75 is formed on the outer edge of the bottle cap 72 , and the peripheral wall 75 enters the slit 33 of the arm 30 to push the second detector 44 . A processing member 74 is rotatably supported on the bottle base 73 , and a magnet 76 to be detected by the first detection section 43 is provided.

When using the decompression bottle 70 , the decompression bottle 70 is placed on the cooker main body 10 and the contact head 31 of the arm 30 is brought into contact with the bottle cap 72 . As a result, the magnet 76 of the bottle base 73 faces the first detection portion 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 magnet 76 of the bottle base 73 is detected by the first detector 43 , and the peripheral wall 75 of the bottle cap 72 is detected by the second detector 44 . The decompression bottle 70 is detected when the first and second detection units 43 and 44 are turned on and the third detection unit 45 is turned off.

Before starting the operation, the control unit 56 refers to the flag in the memory to confirm 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 prohibits the vacuum pump 42 from being driven. In this manner, when the current to the motor 41 is insufficient, the pressure reduction operation preceding the machining operation by the motor 41 is stopped. Therefore, it is possible to prevent the vacuum pump 42 from being driven in a situation where proper cooking cannot be expected due to a decrease in the output of the motor 41, and 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 decompression 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 stops and the decompression of the decompression bottle 70 is completed, the motor 41 is driven to rotate the processing member 74 to process the food. By processing foodstuffs in a decompressed state, the foodstuffs can be processed to a uniform particle size while suppressing the loss of nutrients due to oxidation of the foodstuffs, and the freshness of the processed foodstuffs 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 bottle main body 81 made of glass, 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 section 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 to be detected by the first detection section 43 is provided. The bottom portion of the heating bottle 80 is made of a thermally conductive material, and inside the bottle base 83 is a heater 87 for heating the ingredients in the heating bottle 80 and a heater 87 for detecting the temperature inside the heating bottle 80. A temperature sensor 88 is provided.

When using the heating bottle 80 , the heating bottle 80 is placed on the cooker main body 10 with the arm 30 accommodated in the recess 23 (see FIG. 2 ) of the side pole 20 . As a result, the magnet 86 of the bottle base 83 faces the first detection portion 43 of the cooker main body 10 , and the magnet 85 on the outer periphery of the bottle cap 82 faces the third detection portion 45 of the arm 30 . The magnet 86 of the bottle base 83 is detected by the first detector 43 , and the magnet 85 of the bottle cap 82 is detected by the third detector 45 . 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.

Before starting the operation, the control unit 56 refers to the flag in the memory to confirm 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 prohibits the heater 87 from being driven. Thus, when the current to the motor 41 is insufficient, the heating operation preceding the machining operation by the motor 41 is stopped. Therefore, the heater 87 will not be driven in a situation where 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 main body 10 of the cooker, and the heater 87 is energized from the main body 10 of the cooker. Also, the heating state of the heating bottle 80 is displayed on the illumination bar 21 of the side pole 20 in the same manner as the depressurized state. The food is processed by the processing member 84 by driving the motor 41 while being heated by the heater 87 . The temperature in the heating bottle 80 is detected by the temperature sensor 88, and the heating of the heater 87 is controlled based on the temperature in the heating bottle 80 to maintain the inside of the heating bottle 80 at a predetermined temperature.

Also, the heating bottle 80 is not used only for cooking with heat. The heating bottle 80 is a container that can be used for cooking with heat, but can also be used for cooking without heating. For example, the heating bottle 80 may be used for heat cooking such as soup cooking in a soup mode described later, or may be used in an unheated state as a coffee grinder in a nut mode described later. Therefore, the heater 87 is not always driven when the heating bottle 80 is set. Therefore, in a heating operation mode such as a nuts mode in which no heating is performed, driving of the heater 87 is disabled regardless of whether or not there is a motor abnormality, and only driving of the motor 41 is prohibited.

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

Since food is not processed in the storage bottle 90, there is no need to drive the motor 41 when the storage bottle 90 is set. The vacuum pump 42 may be driven to start the depressurization operation because the food is not wasted even if the motor malfunctions. Since the motor 41 is not moved, the pressure reducing operation may be permitted without executing the motor abnormality determination process. As described above, the storage bottle 90 in which the motor 41 is not driven does not require motor abnormality determination processing. good.

Moreover, the cooking appliance 1 is provided with a warning unit 59 that warns of motor abnormality when the control unit 56 determines that the motor is abnormal. As a result, the user can be notified of the motor abnormality and the cooking of the food can be stopped. Note that the warning unit 59 may be configured to warn the user of the motor abnormality, and may be warned by, for example, a buzzer warning, an audio warning, a light emitting warning, a display warning, or a combination thereof. Further, when the cooker 1 is wirelessly connected to the user's mobile terminal, the cooker 1 may transmit a motor abnormality warning signal to the mobile 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. As shown in FIG. Operation mode lamps 61a-61g indicate soymilk mode, soup mode, paste mode, nut mode, smoothie mode, frozen mode, and manual mode from the left in the figure. Error lamps 62a-62d indicate, from the left in the figure, an installation error, a pressure error, an overfilling error, and a temperature error. A time adjustment lamp 63 indicates a time adjustment mode, and a speed adjustment lamp 64 indicates a speed adjustment mode.

Further, 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 vacuum cooking processing time. The dial switch 66 is used for switching operation modes, adjusting operation time, and adjusting speed. The push switches 67a-67c are a flash switch, a start switch, and a release switch from the left in the drawing. The flash switch performs stirring only while being pressed, the start switch starts various operations when pressed, 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 to select the operation mode. At this time, selectable operation modes are restricted according to the type of bottle. For example, in the case of the decompression bottle 70, when the dial switch 66 is turned, only the operation mode lamps 61e to 61g are turned on in order, and the operation mode for heating cannot be selected. In the case of the heating bottle 80, when the dial switch 66 is turned, only the operation mode lamps 61a to 61d are lit in order, and the operation mode for pressure reduction cannot be selected.

In this 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 operation mode for heating cannot be selected when the decompression bottle 70 is set, the decompression bottle 70 that does not correspond to the operation mode for heating is not erroneously heated. In addition, since the operation mode for decompression cannot be selected when the heating bottle 80 is set, the heating bottle 80 that does not correspond to the operation mode for decompression will not be erroneously decompressed. In this way, the operation modes are limited so that the cooking operation suitable for the type of bottle is selected.

Next, referring to FIG. 8, the processing operation by the cooker will be described. FIG. 8 is a diagram showing a flowchart of the machining operation of this embodiment. Note that the flowchart of FIG. 8 shows an example of the processing operation, and the processing operation is not limited to this, and for example, the order of processing may be partially changed. Moreover, in FIG. 8, the code|symbol of FIG. 4 is used and demonstrated for convenience of explanation.

As shown in FIG. 8, when the cooker 1 is turned on, the type of bottle set in the cooker 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. When the detection unit 44 is OFF, the heating bottle 80 is detected. As a result, it is possible to select an operation mode according to the type of bottle. Note that when the storage bottle 90 is set in the cooker 1, all of the first to third detection units 43 to 45 are turned off, as in the case where none of the bottles is set in the cooker 1. It has become.

Next, when the type of bottle is detected by the cooker 1, the controller 56 performs motor abnormality determination processing (step S02). In this case, it is checked whether 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). Further, the process proceeds to step S11 without starting the cooking operation, and the series of cooking operations by the cooker 1 is prohibited. As a result, food is not wasted due to incomplete cooking due to motor malfunction.

On the other hand, if 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 bottle is started (step S04). When the decompression bottle 70 is detected, the decompression mechanism performs the decompression operation, and when the heating bottle 80 is detected, the heater 87 performs the heating operation. Next, when the pressure reducing operation or the heating operation is completed, the machining member 74 is rotationally driven by the motor 41 to start the machining operation (step S05). As a result, the food material 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 I flowing through the motor 41 is detected by the current detector 55 (step S06). A current value I of the motor 41 detected by the current detector 55 is output to the controller 56 . Next, in the control unit 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). When the current value I of the motor 41 is equal to or greater than the predetermined threshold value 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, if 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 the current value I of the motor 41 is equal to or less than a predetermined threshold value T2 indicating current shortage. is determined (step S08). When the current value I of the motor 41 is equal to or less than the predetermined threshold value 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 determining whether the current is insufficient, the current value I of the motor 41 is compared with the threshold value T2, avoiding immediately after the start of machining and immediately before the end of operation, so as not to detect a motor abnormality when the motor 41 rises and falls.

Next, it is determined whether or not the machining operation is finished (step S10), and the processing from step S06 to step S08 is repeated until the machining operation is finished. When the processing operation ends, it is determined whether or not the power of the cooker 1 has been turned off (step S11). If the power of the cooker 1 has not been turned off (No in step S11), the process starts from step S01. be. If it is determined that the motor is abnormal by current detection during the processing operation in the current cooking operation, the flag indicating the motor abnormality is set in the memory. Cooking action is prohibited.

As described above, in the cooker 1 of the present embodiment, when the current to the motor 41 is insufficient, it is determined that the motor is abnormal. . Therefore, it is possible to avoid unexpected troubles such as stopping of the motor 41 in the middle of the cooking operation, and it is possible to keep the motor 41 moving stably.
