Can be transmitted to the rotating shaft 131, and the cooking member 132 can be rotated to cook the food.

The hardware configuration of the electric cooker 100 will be described with reference to FIG. FIG. 4 is a block diagram showing a hardware configuration of the electric cooker 100. The electric cooker 100 mainly includes a control unit 170, a storage unit 180, an operation unit 115, a load detection unit 136, a pressure detection unit 147, a suction unit 140, and a drive unit 150.

The control unit 170 is composed of, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 170 controls each unit of the electric cooker 100 by reading and executing a program stored in the storage unit 180. The storage unit 180 is, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), or the like, and stores a program executed by the control unit 170, various parameters used by the control unit 170, and the like.

The operation unit 115 receives a command from the user and inputs it to the control unit 170. The load detection unit 136 detects the load of the drive unit 150, and inputs the detected value to the control unit 170. The pressure detection unit 147 detects the pressure inside the accommodating unit 120, and inputs the detected value to the control unit 170. The control unit 170 controls the suction unit 140 and the drive unit 150 based on the input information.

FIG. 5 is a block diagram showing a functional configuration of the control unit 170 of the electric cooker 100. As shown in FIG. 5, the control unit 170 calculates the suction time acquisition unit 171 that acquires the suction time by the suction unit 140 and the amount of foodstuffs (hereinafter, also referred to as the amount of foodstuffs) contained in the storage unit 120. A cooking time setting unit 172 that sets the cooking time based on the calculated food amount, a cooking time correction unit 174 that corrects the set cooking time, and a drive that controls the drive unit 150. It includes a control unit 175. The cooking time here refers to the driving time of the driving unit 150.

The suction time acquisition unit 171 acquires the suction time by the suction unit 140. In the electric cooker 100, the suction unit 140 is driven based on a command from the control unit 170. When the control unit 170 drives the suction unit 140 and determines that the detection value of the pressure detection unit 147 is equal to or less than a predetermined threshold value, that is, when the inside of the accommodating unit 120 reaches a predetermined pressure, the suction unit 140 Stop driving. During this time, the control unit 170 measures the operating time of the suction unit 140, and the suction time acquisition unit 171 acquires the measured suction time by the suction unit 140 when the suction operation by the suction unit 140 is completed.

The foodstuff amount calculation unit 172 calculates the amount of foodstuff to be stored inside the storage unit 120. The food material amount calculation unit 172 calculates the volume of the storage unit 120 obtained by subtracting the volume of the food material from the suction capacity and suction time of the suction unit 140. The storage unit 180 stores the volume of the accommodating unit 120 in advance. The food material amount calculation unit 172 calculates the food material amount, which is the volume of the food material, by subtracting the volume of the storage unit 120 excluding the volume of the food material from the volume of the storage unit 120 stored in the storage unit 180.

The cooking time setting unit 173 sets the cooking time based on the calculated amount of ingredients. The cooking time here is the time required to cook the ingredients based on the hardness of the standard ingredients, and is a value preset according to the amount of the ingredients. In the storage unit 180, the amount of ingredients and the cooking time are stored in association with each other. The cooking time setting unit 173 sets the cooking time by referring to the information stored in the storage unit 180 from the amount of ingredients calculated by the ingredient amount calculation unit 172.

As described above, the control unit 170 can set the drive time (cooking time) of the drive unit 150 based on the suction time by the suction unit 140. Specifically, the amount of foodstuff is calculated from the suction time by the suction unit 140, and the driving time of the drive unit 150 is set based on the calculated amount of foodstuff, so that the cooking time is automatically adjusted according to the amount of foodstuff. can do. In the above configuration, the amount of ingredients is calculated from the suction time to set the cooking time, but the cooking time is not limited to this, and the storage unit associates an arbitrary suction time with the cooking time corresponding to the suction time in advance. It may be stored in 180. In this case, when the suction time is acquired by the suction time acquisition unit 171, the cooking time corresponding to the suction time is acquired by referring to the information stored in the storage unit 180.

The drive control unit 175 is for controlling the drive unit 150. When the cooking time is set by the cooking time setting unit 173, the driving unit 150 is driven at the set cooking time. Further, when the cooking time set in the cooking time correction unit 174 is corrected, the drive control unit 175 drives the drive unit 150 with the corrected cooking time.

The cooking time correction unit 174 corrects the set cooking time based on the load of the drive unit 150. Here, it is assumed that the load related to the rotation of the cooking unit 130 (cooking member 132) is detected by detecting the load of the driving unit 150.

As an example, the cooking time correction unit 174 makes one rotation of the cooking member 132 when the driving unit 150 is started, specifically, after the driving unit 150 is driven, that is, after the cooking operation is started. The cooking time is corrected based on the load (hereinafter, also referred to as the load in one rotation of the cooking unit 130).

Specifically, the cooking time correction unit 174 determines whether or not the load in one rotation of the cooking unit 130 is equal to or greater than a predetermined threshold value. The predetermined threshold value is a value preset with reference to the hardness of a standard food material, and is stored in the storage unit 180. When it is determined that the load in one rotation of the cooking unit 130 is equal to or higher than a predetermined threshold value, the cooking time correction unit 174 determines the cooking time as the hardness of the food material is harder than the standard hardness. Correct to lengthen the time. When it is determined that the load in one rotation of the cooking unit 130 is not equal to or more than a predetermined threshold value, that is, smaller than the predetermined threshold value, the cooking time correction unit 174 determines that the hardness of the food material is softer than the standard hardness. Assuming that, the cooking time is corrected to be shortened by a predetermined time.

As a result, the cooking time can be automatically adjusted according to the hardness of the ingredients. When the cooking member 132 does not reach one rotation within a certain period of time after driving the drive unit 150, the cooking time correction unit 174 stores very hard foodstuffs or foodstuffs exceeding a specified amount in the storage unit 120. The drive of the drive unit 150 may be stopped. As a result, it is possible to prevent the motor and the like from being damaged by the load on the drive unit 150. Further, the cooking time is corrected based on the load in one rotation of the cooking unit 130, but the cooking time is not limited to this, from the start of driving the driving unit 150 until the cooking member 132 reaches a predetermined rotation speed, or The cooking time may be corrected based on the load required to reach the predetermined time. Further, when the cooking time is corrected, the cooking time is configured to be longer or shorter for a predetermined time, but the present invention is not limited to this, and for example, the difference between the load in one rotation of the cooking unit 130 and the predetermined threshold value. Based on this, the cooking time to be corrected may be adjusted. Further, the cooking time is not limited to the predetermined threshold value, and a predetermined threshold value range may be set so as to correct the cooking time when the load in one rotation of the cooking unit 130 deviates from the predetermined threshold value range. In this case, if the load in one rotation of the cooking unit 130 is within the predetermined threshold range, the cooking time is not corrected, and if it is equal to or more than the upper limit of the predetermined threshold range, the cooking time is corrected to be lengthened. , When it is not more than the lower limit of the predetermined threshold range, the cooking time is corrected to be shortened.

Further, the cooking time correction unit 174 determines whether or not the load of the drive unit 150 is equal to or less than a predetermined threshold value. The predetermined threshold value is a value predetermined by an experiment or the like, refers to a load value in a state where cooking of the food material is almost completed, and is stored in the storage unit 180. When the cooking time correction unit 174 determines that the load of the driving unit 150 is equal to or less than a predetermined threshold value, it is assumed that the cooking of the ingredients is completed, and the cooking time correction unit 174 drives the cooking time regardless of the cooking time set by the cooking time setting unit 173. The drive of the unit 150 is stopped. When the cooking time correction unit 174 determines that the load of the driving unit 150 is not equal to or less than a predetermined threshold value, the cooking time correction unit 174 does not correct the cooking time, assuming that the cooking of the ingredients has not been completed yet.

When determining whether or not the cooking of the food material is completed, it is preferable to determine whether or not the load of the drive unit 150 is continuously below the predetermined threshold value for a predetermined period or a predetermined number of times. When it is determined that the load of the driving unit 150 is continuously equal to or less than a predetermined threshold value for a predetermined period or a predetermined number of times, the cooking time correction unit 174 drives the driving unit 150 assuming that the cooking of the foodstuff is completed. Correct the cooking time to stop. When it is determined that the load of the driving unit 150 is not continuously below a predetermined threshold value for a predetermined period or a predetermined number of times, the cooking time correction unit 174 corrects the cooking time by assuming that the cooking of the ingredients has not been completed yet. Do not do.

As a result, it is possible to prevent the driving unit 150 from being driven, that is, continuing the cooking operation even though the cooking of the food material is completed.

Further, the cooking time correction unit 174 can correct the cooking time based on the fluctuation amount of the load of the drive unit 150. As an example, the cooking time correction unit 174 determines whether or not the difference between the maximum value and the minimum value of the load detected in a predetermined period is equal to or greater than the reference value. The reference value is a value predetermined by an experiment or the like and is stored in the storage unit 180. The predetermined period refers to, for example, the period from the start of the cooking operation to the elapse of a predetermined time. When it is determined that the difference between the maximum value and the minimum value of the load detected in the predetermined period is equal to or greater than the reference value, the cooking time correction unit 174 corrects the cooking time so as to increase the cooking time by a predetermined time. The cooking time correction unit 174 does not correct the cooking time when it is determined that the difference between the maximum value and the minimum value of the load detected in the predetermined period is smaller than the reference value.

As a result, even if the hardness of the ingredients varies, the cooking time can be adjusted according to the degree of variation. The cooking time is corrected by using the difference between the maximum value and the minimum value of the load detected in the predetermined period, but the cooking time is not limited to this, for example, the dispersion value of the load detected in the predetermined period. The cooking time may be corrected according to the amount indicating the degree of load variation by calculating the amount indicating the degree of load variation. Further, when the cooking time is corrected, it is configured to be lengthened by a predetermined time, but the cooking time is not limited to this, and is corrected based on, for example, the difference between the load fluctuation amount and the reference value. May be adjusted.

The automatic cooking process by the electric cooker 100 will be described with reference to FIG. FIG. 6 is a flowchart showing an automatic cooking process by the electric cooker 100. Here, it is assumed that the cooking operation in which the ingredients are cooked after the internal air is discharged is started.

The control unit 170 determines whether or not the suction operation by the suction unit 140 is completed (step S101). When the control unit 170 determines that the suction operation by the suction unit 140 is completed, the suction time acquisition unit 171 acquires the suction time by the suction unit 140 (step S102). When the control unit 170 determines that the suction operation by the suction unit 140 has not been completed, the control unit 170 repeats step S101. Then, the food material amount calculation unit 172 calculates the food material amount based on the suction time acquired by the suction time acquisition unit 171 (step S103). The cooking time setting unit 173 sets the cooking time based on the amount of foodstuffs calculated by the foodstuff amount calculation unit 172 (step S104). The drive control unit 175 drives the drive unit 150 based on the cooking time set by the cooking time setting unit 173 (step S105). The cooking time correction unit 174 performs a cooking time correction process based on the load of the drive unit 150 (step S106). The control unit 170 determines whether or not the set or corrected cooking time has ended (step S107). When the control unit 170 determines that the set or corrected cooking time has been reached, the cooking operation is terminated. When the control unit 170 determines that the set or corrected cooking time has not been reached, the control unit 170 repeats step S107.

A first embodiment of the cooking time correction process by the cooking time correction unit 174 of the electric cooker 100 will be described with reference to FIG. 7. FIG. 7 is a flowchart showing a first embodiment of the cooking time correction process by the cooking time correction unit 174.

When the drive unit 150 is driven by the drive control unit 175, the cooking time correction unit 174 acquires the load related to the period from the start of the cooking operation to the rotation of the cooking unit 130 (cooking member 132) (cooking member 132). Step S201). Then, the cooking time correction unit 174 determines whether or not the acquired load is equal to or greater than a predetermined threshold value (step S202). When the cooking time correction unit 174 determines that the acquired load is equal to or higher than a predetermined threshold value (Yes in step S202), the cooking time correction unit 174 increases the cooking time set by the cooking time setting unit 173 by a predetermined time. The correction (step S203) is performed and the correction process is completed. When the cooking time correction unit 174 does not determine that the acquired load is not equal to or higher than a predetermined threshold value (No in step S202), the cooking time correction unit 174 corrects the cooking time set by the cooking time setting unit 173 to be shortened by a predetermined time. (Step S204), the correction process is completed.

A second embodiment of the cooking time correction process by the cooking time correction unit 174 of the electric cooker 100 will be described with reference to FIG. FIG. 8 is a flowchart showing a second embodiment of the cooking time correction process by the cooking time correction unit 174.

When the drive unit 150 is driven by the drive control unit 175, the cooking time correction unit 174 acquires the load of the drive unit 150 (step S301). The cooking time correction unit 174 determines whether or not the load of the drive unit 150 is continuously below the predetermined threshold value for a predetermined period or a predetermined number of times (step S302). When the cooking time correction unit 174 determines that the load of the driving unit 150 is continuously below the predetermined threshold value for a predetermined period or a predetermined number of times (in the case of Yes in step S302), the cooking time setting unit 173 Regardless of the set cooking time, the cooking time is corrected so as to stop the driving of the drive unit 150 (step S303), and the correction process ends. When the cooking time correction unit 174 determines that the load of the driving unit 150 does not fall below the predetermined threshold value continuously for a predetermined period or a predetermined number of times (No in step S302), the cooking time is corrected. However, the correction process ends.

When the drive unit 150 is driven by the drive control unit 175, the cooking time correction unit 174 acquires the load detected in a predetermined period (step S401). The cooking time correction unit 174 determines whether or not the difference between the maximum value and the minimum value is equal to or greater than the reference value under the acquired load of the drive unit 150 (step S402). When the cooking time correction unit 174 determines that the difference is equal to or greater than the reference value (Yes in step S402), the cooking time correction unit 174 corrects the cooking time set by the cooking time setting unit 173 to be lengthened by a predetermined time (step S403). ), And the correction process is completed. When the difference is equal to or less than the reference value (when No in step S402), the cooking time correction unit 174 does not correct the cooking time, and the correction process ends.

In the above configuration, the three forms of the cooking time correction process are shown individually, but the present invention is not limited to this, and each form may be combined to correct the cooking time. The present invention is not limited to the above embodiment, and various modifications are possible. For example, it can be replaced with a configuration that is substantially the same as the configuration shown in the above embodiment, a configuration that exhibits the same action and effect, or a configuration that can achieve the same purpose.
