In addition, the cooking apparatus 800 in the above embodiment provided by the present invention may further have the following additional technical features:
in the above embodiment, the cooking apparatus 800 further includes: and the control panel is connected with the control device 700 of the cooking equipment, and data information is transmitted between the control panel and the control device 700 of the cooking equipment.
In this embodiment, the cooking apparatus 800 is further provided with a control board, wherein the control board is connected to the control device 700 of the cooking apparatus and transmits data information to the control device 700 of the cooking apparatus, so as to set parameters of the cooking apparatus 800 according to the transmitted data information, thereby improving the intelligence of the cooking apparatus 800.
In one embodiment of the present invention, the parameter of the cooking apparatus 800 may be an operation parameter of the microwave device 802, such as the first time period and the second time period, the total time period of the operation of the microwave device 802, and may also be a current operation mode of the cooking apparatus 800, such as a frying function, a stir-frying function, a frying function, and the like.
In the above embodiment, the cooking apparatus 800 includes: any one of an electromagnetic oven, a microwave oven, a micro-steaming and baking integrated machine and an electric baking pan.
It is noted that the cooking apparatus 800 includes an induction cooker, a microwave oven, a micro-steaming and baking all-in-one machine, and an electric baking pan, but is not limited thereto, and the cooking apparatus 800 may be understood as an apparatus that includes a microwave device 802 and a data transmission device 804 and processes food by operating a control method as the above-described cooking apparatus 800.
In any of the embodiments described above, as shown in FIG. 9, the microwave apparatus 802 may be understood to include a microwave source and a microwave receiverAn arrangement of control circuits connected to a microwave source generates microwaves of intensity shown in fig. 10, in particular, a duty cycle T including a first duration T as shown in fig. 10, when the microwave arrangement 802 is operated periodicallyonAnd a second duration ToffThe data transmission device 804 is in the second time period ToffAnd carrying out data transmission.
In an embodiment of the present invention, the data transmission device 804 performs transmission of data information, including two parts, namely sending and receiving data, and specifically, as shown in fig. 11, the data transmission device 804 (for example, a WiFi module) performs communication of data information with a router (or other AP).
The WiFi module transmits using a WiFi protocol, specifically, using a carrier sense multiple access/collision avoidance (CSMA/CA) mechanism, when the data transmission device 804 is to transmit data to a router (or other AP), the WiFi module is close to a microwave source and is greatly affected by microwave interference, and before transmitting data, due to the CSMA/CA mechanism, it may first detect whether a current channel is idle, that is, whether microwave interference exists. When the current channel is detected as not being idle, i.e. at the above TonDuring the time, the module generates a back-off waiting time (namely a first set time length) and then detects the time again until the time is ToffIn the time period, data is sent only when the current channel is detected to be idle, so that the interference of microwaves on WiFi signals is avoided.
When a router (or other APs) needs to send data to a WiFi module, the router is generally far away from a microwave source, the router is less affected by microwave interference and cannot detect microwave interference, channel detection is usually in an idle state, data can be directly sent from a router end, after sending, the router is in a state of waiting for ACK (acknowledgement character, namely an acknowledgement instruction corresponding to data information in the application), and the WiFi module is confirmed to normally receive the data; when the WiFi signal reaches the position near the WiFi module, the influence of microwave interference is large, and when the WiFi signal is at TonIn the time period, the WiFi signal is interfered by microwave, data is in error, the WiFi module cannot receive correct data, and ACK (acknowledgement character) is not returned; when the router waits for ACKAfter time out, the original data is retransmitted, and then the ACK is continuously waited; when at ToffAnd in the time period, the WiFi signal has no microwave interference, the WiFi module receives correct data and simultaneously returns ACK (acknowledgement character), and the router receives the ACK and then successfully sends the data.
In an embodiment of the present invention, as shown in fig. 12, the cooking apparatus 800 is a microwave oven, and the data transmission device 804 uses a control board and an Application program (APP, which is loaded on a mobile phone or a computer) to transmit data information, where the control board may be a main control board of the microwave oven, and when the main control board of the microwave oven is to send data to the APP on the mobile phone or the computer, the main control board first sends data from the main control board to control the WiFi module to directly send data, and after sending, the main control board is in a state of waiting for receiving a confirmation frame of the sent data to confirm that the APP normally receives the data; when at TonIn the time period, the WiFi signal is interfered by microwave, data is in error, the APP cannot receive correct data, and a confirmation frame cannot be returned; when the main control board waits for the overtime of the confirmation frame, the main control board retransmits the original data and then continues to wait for the confirmation frame; when at ToffDuring the time quantum, the wiFi signal does not have microwave interference, and the APP receives correct data, returns the acknowledgement frame simultaneously, and after the main control board received the acknowledgement frame, data transmission succeeded.
When the APP on the mobile phone or the computer needs to send data to the main control board of the microwave oven, the data is sent from the APP first, the router (or other APs) is controlled to directly send the data, after the data is sent, the APP is in a state of waiting for receiving a confirmation frame of the sent data, and the main control board is confirmed to normally receive the data; when at TonIn the time period, the WiFi signal is interfered by microwave, data is wrong, the main control board cannot receive correct data, and a confirmation frame cannot be returned; when the APP waits for the acknowledgement frame to be overtime, the APP retransmits the original data and then continues to wait for the acknowledgement frame; when at ToffDuring the time quantum, the wiFi signal does not have microwave interference, and the main control board receives correct data, returns the acknowledgement frame simultaneously, and APP receives after the acknowledgement frame, data transmission is successful.
In this embodiment, since a circuit for detecting a characteristic value of a frequency, a voltage, an instruction, or the like of the microwave or the WiFi is not required, interference between data transmission and the microwave is reduced without increasing the manufacturing cost of the product.
