This application claims priority to Taiwanese Patent Application No. 107100938, filed on Jan. 10, 2018.
This disclosure relates to a cooking apparatus, more particularly to a cooking apparatus capable of automatically cooking food.
Food safety has gained increasing attention in recent years. As a result, more and more people tend to cook by themselves at home. Since a conventional cooking apparatus (e.g., a gas stove, a microwave oven, an induction cooker, an oven, etc.) typically has only one cooking function (i.e., a single heating manner), a user who wishes to cook in multiple different ways may need a lot of room for placing two or more cooking apparatuses. Even though some composite cooking apparatuses provide multiple cooking functions, it is relatively difficult for a user having little experience in cooking food to cook properly using such composite cooking apparatuses.
Therefore, the present disclosure is to provide a cooking apparatus capable of automatically cooking food and adjusting operation condition and operation time duration for cooking food.
According to this disclosure, a cooking apparatus is provided. The cooking apparatus is configured to cook ingredients packaged together in a package. The package is provided with a barcode representing data related to information about the ingredients. The cooking apparatus includes a cooking device and a barcode reader. The cooking device includes a housing, a cooking unit and a control unit. The housing defines a cooking room for accommodating the ingredients therein. The cooking unit is configured to heat contents in the cooking room. The control module is electrically connected to the cooking unit for controlling operation of the cooking unit. The barcode reader is electrically connected to the control module, and is configured to scan the barcode on the package. The barcode reader is further configured to decode the barcode so as to obtain the data represented by the barcode, and to transmit the data to the control module. The control module controls operation of the cooking unit based on the information contained in the data received from the barcode reader.
Other features and advantages of the present disclosure will become apparent in the following detailed description of the embodiments of the disclosure, with reference to the accompanying drawings, in which:
Referring to
The cooking apparatus 100 includes a cooking device 1 and a barcode reader 2. The cooking device 1 includes a housing 10, a cooking unit 12 and a control module 14. The housing 10 defines a cooking room 101 for accommodating the ingredients 4 therein. The cooking unit 12 is electrically connected to the control module 14, and is configured to operate in a plurality of operation modes as controlled by the control module 14 to heat contents in the cooking room 101. The position of the cooking unit 12 depicted in
The control module 14 is configured to automatically control operation of the cooking unit 12 such as selecting one of the operation modes and adjusting the operating condition and/or the operation time duration for the selected one of the operation modes. The term “control module” may refer to any device or portion of a device that processes electronic data from registers and/or memory to transform that electronic data into other electronic data. For example, the control module 14 may include, but not limited to, a single core processor, a multi-core processor, a dual-core mobile processor, a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA) an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), etc.
The barcode reader 2 is electrically connected to the control module 14, and is configured to scan the barcode 31 on the package 3, to decode the barcode 31 so as to obtain the data represented by the barcode 31, and to transmit the data to the control module 14. In one embodiment, upon receipt of the data represented by the barcode 31, the control module 14 controls operation of the cooking unit 12 based on the information contained in the data received from the barcode reader 2. The control module 14 is programmed to execute a cooking program for cooking the ingredients 4 where the control module 14 automatically selects and schedules at least two of the operation modes and automatically adjusts the operating condition and/or the operation time duration for a currently-executed one of the at least two operation modes. In one embodiment, the data represented by the barcode 31 includes instructions related to the cooking program for cooking the ingredients 4, and the control module 14 is programmed to execute the instructions for implementing the cooking program. For example, to cook the ingredients 4 originally packaged together in the package 3, the ingredients 4 are first put in a container such as a bowl (see
In one embodiment, the cooking device 1 further includes an image capturing module 13 and a display 17 that are electrically connected to the control module 14. The image capturing module 13 is a camera configured to capture an image inside the cooking room 101 and to transmit the image to the control module 14. For example, the image capturing module 13 captures the image inside the cooking room 101 when the control module 14 determines that the door of the housing 10 is closed and the data related to the information about the ingredients 4 is received from the barcode reader 2. The control module 14 further analyzes the image received from the image capturing module 13 to determine whether the cooking room 101 has placed therein the ingredients 4 corresponding to the information. Specifically, the control module 14 analyzes the image to determine whether the image received from the image capturing module 13 has the image features that are included in the information contained in the data represented by the barcode 31. When the image has all the image features included in the information, the control module 14 determines that the cooking room 101 has all the ingredients 4 placed therein, and activates and controls operation of the cooking unit 12 to heat the contents in the cooking room 101 according to the cooking program. When the image does not have all the image features, the control module 14 determines that the cooking room 101 does not have all the ingredients 4 placed therein, and outputs a notification/alert such as a voice message or to control the display 17 to display a result of the determination to notify the user of the result of the determination. It should be noted that the operation panel 15 can be integrated with the display as a touch screen in some embodiments of this disclosure.
In some embodiments, the cooking device 1 further includes a storage unit 16 that is electrically connected to the control module 14, and that stores a plurality of reference image features that are related respectively to a plurality of ingredient items. In such case, the control module 14 accesses the storage unit 16 to acquire corresponding ones of the reference image features of the ingredient items that correspond respectively to the ingredients 4 based on the names of the ingredients 4 included in the information. Then, the control module 14 analyzes the image received from the image capturing module 13, and determines whether the image has the corresponding ones of the reference image features that are acquired from the storage unit 16. The control module 14 determines that the cooking room 101 has all the ingredients 4 placed therein when the image has all the corresponding ones of the reference image features, and determines that the cooking room 101 does not have all the ingredients 4 placed therein when otherwise.
In one embodiment, upon determining that the cooking room 101 has the ingredients 4 placed therein, the control module 14 further analyzes the image received from the image capturing module 13 to further determine whether the ingredients 4 are placed at the predetermined location in the cooking room 101 based on the information contained in the data represented by the barcode 31. In some embodiments, the control module 14 compares the image received from the image capturing module 13 with a pre-stored image that indicates the predetermined location to determine whether the ingredients 4 are placed at the predetermined location. The control module 14 activates and controls operation of the cooking unit 12 to heat the contents in the cooking room 101 based on the information contained in the data when determining that the cooking room 101 has all the ingredients 4 placed therein and that the ingredients 4 are placed at the predetermined location. When determining that the ingredients 4 are not placed at the predetermined location, the control module 14 outputs a notification to notify the user of the result of the determination by, for example, controlling the display 17 to display the notification.
In one embodiment, the cooking device 1 further includes a weighing unit 18 (e.g., an electric weight scale) electrically connected to the control module 14. The weighing unit 18 is mounted at a bottom of the housing 10, and is configured to weigh the contents in the cooking room 101 and to transmit a weight of the contents to the control module 14. Upon determining that the cooking room 101 has the ingredients 4 placed therein and at the predetermined location, the control module 14 further determines whether the weight of the contents in the cooking room 101 conforms with the predetermined total weight of the ingredients 4 based on the information. The control module 14 further controls the display 17 to display a result of the determination, and activates and controls operation of the cooking unit 12 according to the cooking program when determining that the cooking room 101 has all the ingredients 4 placed therein, that the ingredients 4 are placed at the predetermined location, and that the weight of the contents in the cooking room 101 is equal to the predetermined total weight. Similarly, when the weight of the contents in the cooking room 101 is not equal to the predetermined total weight, the control module 14 further outputs a notification such as a voice message to notify the user of the result of the determination.
In some embodiments, the control module 14 activates and controls operation of the cooking unit 12 according to the cooking program when determining that the cooking room 101 has all the ingredients 4 placed therein and that the weight of the contents in the cooking room 101 is equal to the predetermined total weight. In some embodiments, the control module 14 does not activate the cooking unit 12 when determining that the cooking room 101 does not have all the ingredients 4 placed therein, that the ingredients 4 are not placed at the predetermined location, or that the weight of the contents in the cooking room 101 is not equal to the predetermined total weight.
In one embodiment, the cooking device 1 further includes a temperature sensing unit 19 electrically connected to the control module 14 and disposed in the cooking room 101. The temperature sensing unit 19 is configured to sense an inside temperature in the cooking room 101 and to transmit the inside temperature to the control module 14. The control module 14 is further configured to adjust the operating condition and/or the operation time duration of the operation of the cooking unit 12 to heat the contents in the cooking room 101 based on the inside temperature sensed by the temperature sensing unit 19 during running of the cooking program. In one embodiment, the temperature sensing unit 19 is further configured to sense a plurality of regional temperatures corresponding respectively in position to a plurality of regions in the cooking room 101, and to transmit the regional temperatures to the control module 14. The control module 14 is further configured to compare the regional temperatures respectively with a plurality of predetermined temperatures, e.g., stored in the storage unit 16 or included in the information contained in the data represented by the barcode 31, and to determine whether to adjust the operating condition or the operation time duration for the cooking unit 12 based on a result of the comparison between the regional temperatures and the predetermined temperatures. In this embodiment, the temperature sensing unit 19 is an infrared camera or a thermographic camera mounted at a top of the housing 10, and is configured to divide a bottom surface of the housing 10 into a 3-by-3 grid with nine rectangular regions, and to sense the regional temperatures respectively of the rectangular regions. It should be noted that the regional temperatures may be considered as surface temperatures of the ingredients 4 that are received in the bowl, and the control module 14 is configured to determine whether the ingredients 4 are overheated and whether the ingredients are heated unevenly based on the surface temperatures. In other embodiments, the temperature sensing unit 19 is an electronic thermometer, a pyrometer, or an infrared thermometer, etc.
In one embodiment, the control module 14 adjusts the operating condition by increasing the heating power level and/or increases the operation time duration for heating, for example, one of the regions in the cooking room 101 when determining that one of the surface temperatures of the ingredients 4 corresponding in position to said one of the regions is lower than the respective predetermined temperature. On the contrary, the control module 14 decreases the heating power level and/or the operation time duration for heating another one of the regions in the cooking room 101 when determining that one of the surface temperatures of the ingredients 4 corresponding in position to the another one of the regions exceeds the respective predetermined temperature. The control module 14 continuously adjusts the operating condition and/or the operating time duration of the cooking unit 12 until the result of the comparison indicates that all of the regional temperatures sensed by the temperature sensing unit 19 conform respectively with the predetermined temperatures.
In one embodiment, the control module 14 is further configured to determine a degree of degradation of the cooking unit 12 based on the result of the comparison between the regional temperatures sensed by the temperature sensing unit 19 and the predetermined temperatures and to determine whether to adjust the operating condition or the operation time duration for the cooking unit 12 based on the degree of degradation of the cooking unit 12. In some embodiments, the control module 14 determines that the cooking unit 12 is degraded when a difference between the regional temperatures sensed by the temperature sensing unit 19 and the predetermined temperatures is greater than a predetermined value. For example, the control module 14 determines the degree of degradation of the cooking unit 12 as a parameter positively correlated to the difference between the regional temperatures and the predetermined temperatures when the regional temperatures sensed by the temperature sensing unit 19 are lower than the predetermined temperatures. In some embodiments, the control module 14 adjusts the operating condition by increasing the heating power level and/or increases the operating time duration of the cooking unit 12 when the degree of degradation is relatively large.
In one embodiment, the control module 14 is further configured to determine the degree of degradation of the cooking unit 12 by comparing an actual output power of the cooking unit 12 with a predetermined output power of the cooking unit 12. It should be noted that the predetermined output power of the cooking unit 12 is a rated output power. The control module 14 is configured to determine whether to adjust the operating condition or the operation time duration of the operation of the cooking unit 12 to heat the contents in the cooking room 101 based on the degree of degradation of the cooking unit 12. For example, the control module 14 obtains the actual output power that is obtained from one of, without limitation, a voltmeter, a galvanometer, etc., determines the degree of degradation of the cooking unit 12 based on a difference between the actual output power and the predetermined output power, and then determines whether to adjust the operating condition or the operation time duration of the cooking unit 12. For example, the control module 14 determines the degree of degradation of the cooking unit 12 as a parameter positively correlated to the difference between the actual output power and the predetermined output power. When the degree of degradation of the cooking unit 12 is relatively large, the control module 14 adjusts the operating condition by increasing the heating power level and/or increases the operating time duration of the cooking unit 12.
In some embodiments, the control module 14 first adjusts the operating condition and/or the operating time duration when the regional temperatures are lower than the predetermined temperatures or the actual output power is different from the predetermined output power, and further determines that the cooking unit 12 is degraded when the adjustment is ineffective.
Note that, when the degree of degradation of the cooking unit 12 reaches a predetermined degree, the control module 14 further controls the display unit 17 to display the degree of degradation of the cooking unit 12 to notify the user that the cooking unit 12 requires replacement (or maintenance).
In one embodiment, the cooking device 1 further includes an ambient temperature sensing unit 11 mounted on, e.g., an outer surface of the housing 10. The ambient temperature sensing unit 11 is electrically connected to the control module 14, and is configured to sense an ambient temperature around the cooking device 1 and to transmit the ambient temperature to the control module 14. The control module 14 is further configured to adjust the operating condition and/or the operation time duration of the operation of the cooking unit 12 to heat the contents in the cooking room 101 based on the ambient temperature. For example, when the ambient temperature is relatively high so the surface temperature of the ingredients 4 in the cooking room 101 sensed by the temperature sensing unit 19 may increase easily, the control module 14 decreases the heating power level or the operating time duration of operation of the cooking unit 12. On the other hand, when the ambient temperature is relatively low so the surface temperature of the ingredients 4 in the cooking room 101 sensed by the temperature sensing unit 19 may not increase easily, the control module 14 increases the heating power level or the operating time duration of the cooking unit 12.
In one embodiment, the control module 14 further controls the display unit 17 to display the operation mode, the operating condition, and the operation time duration (or the remaining operation time) of the operation of the cooking unit 12 as the cooking unit 12 heats the contents in the cooking room 101.
The information about the ingredients 4 obtained from the barcode 31 further includes traceability information for each of the ingredients 4, such as a source (a place of origin) of the ingredient 4, a shipping history of the ingredients 4, a processing/producing method by which the ingredients 4 were obtained, an expiration date of the ingredients 4, and a preservation manner for the ingredients 4. Such information may also be displayed on the display unit 17 as controlled by the control module 14.

Additionally, in one embodiment, the cooking device 1 further includes a communication module 140 (see
To sum up, in the present disclosure, with the information about the ingredients 4 to be cooked is included in the barcode 31 or stored in the storage unit 16, a user can operate the barcode reader 2 to read and decode the barcode 31 to thereby automatically activate and control operation of the cooking unit 12 as controlled by the control module 14 according to the cooking program based on the information about the ingredients. Further, the control module 14 is capable of automatically adjusting the operating condition and/or the operation time duration of the cooking unit 12 based on, e.g., the regional temperatures inside the cooking room 101, the degree of degradation of the cooking unit 12, the ambient temperature, or a combination thereof to ensure that the contents in the cooking room 101 are cooked properly.
