It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity, and the same elements are denoted by the same reference numerals, and thus the description thereof will be omitted.

The invention provides a control method for a cooking appliance and the cooking appliance. The cooking utensil of the invention can be an electric lunch box and the like. The present embodiment will explain a method of controlling a cooking appliance and a cooking appliance, taking an electric lunch box as an example, with reference to fig. 1 and 2.

The electric lunch box is a lunch box capable of being heated by electricity, the electric lunch box is provided with a heating module, and the electric lunch box can have various cooking modes, such as a low-sugar meal mode, a cold-food making mode and the like. After the electric lunch box is communicated with the power supply, under the low-sugar mode, the food materials (generally, rice, noodles, vegetables, meat and the like which are cooked in advance by a user) in the electric lunch box can be reheated to a preset temperature, so that the electric lunch box is convenient for the user to eat; in the mode of making cold food, raw materials in the electric lunch box, such as cold food used for making jelly or yoghourt, can be processed into finished products, so that the electric lunch box is convenient for users to eat.

The electric lunch box is provided with a temperature detection module and a control module generally, the temperature detection module is used for detecting the temperature in the electric lunch box in real time and feeding back the sensed temperature signal to the control module, so that the control device can realize more accurate control on the cooking process based on the temperature signal. It is understood that the control module is capable of performing a corresponding cooking process according to a predetermined cooking profile in a specific cooking mode. In one embodiment, if the user selects the low-sugar rice mode, the heating module is controlled to stop heating when the temperature of the food material in the electric rice box reaches a preset temperature during the cooking mode.

The electric lunch box may have an interactive module, which may be used to provide the user with various cooking settings, such as setting a cooking mode, cooking taste, etc. The interaction module can be various keys, a touch pad or a touch screen. The interaction module can also comprise an LED lamp, a four-position eight-section nixie tube, a buzzer/loudspeaker, a display unit or other devices, and is used for displaying the cooking function of the cooking appliance, the cooking time and state set by a user or in the cooking process and prompting the cooking state of the user through the buzzer or voice.

The electric lunch box can also be provided with a wireless communication module for information interaction with the terminal. The wireless communication module can be Bluetooth or WIFI. The terminal can be a mobile phone, a sports bracelet, a sports watch and the like, and the terminal is generally provided with a wireless communication module. For example, when the terminal and the lunch box both start the bluetooth function, the terminal and the lunch box can realize the interaction of information by establishing the bluetooth connection. It can be understood that the user can not only directly set the cooking function through the interactive module of the electric lunch box, but also set the cooking function through the terminal. Further, the terminal can be also interconnected with the cloud, so that the cooking process information and the cooking preference information recorded by the terminal can be synchronized through the cloud.

It should be noted that although a partial structure of the electric lunch box is schematically described at this time, these lists are only exemplary and are not intended as a structural limitation of the cooking appliance of the present invention.

The invention also provides a control method of the cooking appliance, which comprises the following steps: acquiring a cooking mode to be executed by the cooking appliance; acquiring a refrigeration starting instruction; and after receiving the refrigeration starting instruction, starting timing, and giving out a prompt when the timing time reaches a preset refrigeration time t.

Specifically, when the timed time reaches the preset refrigerating time t, voice prompt information or terminal prompt information can be sent out. The voice prompt message may be sent out through a prompt module of the cooking appliance, such as a buzzer/horn. Of course, the terminal prompt information may be transmitted to the terminal (such as a mobile phone) through the wireless communication module.

More specifically, the predetermined refrigerating time period t may be determined according to a cooking mode to be performed and an initial temperature of food in the cooking appliance before starting refrigerating, and determining the predetermined refrigerating time period t of the food according to the cooking mode and the initial temperature may include:

determining a preset refrigerating time t according to a first preset rule; the first preset rule comprises a pre-stored cooking mode, pre-stored temperature information, a first corresponding relation and alternative refrigerating time, and the first corresponding relation is used for representing the two-to-one corresponding relation of the pre-stored cooking mode, the pre-stored temperature information and the alternative refrigerating time.

It is understood that the first preset rule is pre-established and stored in the memory chip of the control module. Thereby, the predetermined refrigerating time period t can be conveniently and rapidly determined according to the initial temperature of the food and the cooking mode to be performed.

Of course, determining the predetermined refrigerating time period t of the food according to the cooking mode and the initial temperature may also include:

the predetermined refrigerating time t is determined according to the following formula:

t is k × ln (T1-T0) + C, where T is a predetermined refrigerating time T, the coefficient k and the constant C are fixed values obtained by experiments, k has a value in a range of 0.2 or more and 5 or less, C has a value in a range of 1h or more and 12h or less, T1 is a target temperature in a cooking mode to be performed, and T0 is an initial temperature.

Illustratively, when the initial temperature T0 of the food is 90 ℃, the cooking mode to be performed is a low-sugar rice mode, and the target temperature T1 thus determined is 5 ℃, and further, after selecting an appropriate coefficient k and constant C, the predetermined refrigerating time period is calculated as 7h according to the formula.

It is understood that the coefficient k, the constant C, and the initial temperature T0 of the food, the preset rule of the cooking mode to be performed may be established in advance, whereby the corresponding coefficient k and the constant C are selected according to the preset rule.

The refrigerating time period t can also be a fixed value determined by tests, such as 10 hours or 12 hours or 24 hours, and is built into the cooking appliance control program.

As can be understood from the foregoing, the electric lunch box of the present embodiment, whether to perform the low-sugar rice mode or the cold food preparation mode, generally requires refrigeration for a certain period of time before performing the corresponding cooking mode in order to obtain good taste and avoid food spoilage, and therefore, starts to count time after determining the predetermined refrigeration period t and after receiving a refrigeration start instruction, and ends the refrigeration when the counted period reaches the predetermined refrigeration period t.

Further, the refrigeration start instruction may be a trigger signal generated after the target key is triggered. It can be understood that the target key can be an operation key arranged on the electric lunch box or an operation key on a terminal connected with the electric lunch box in an internet of things mode. Thereby, both the terminal (such as a mobile phone) and the cooking appliance itself may be operated to produce the trigger signal.

Of course, in other embodiments, for example, the electric lunch box and the terminal implement information interaction through the wireless communication module, then the refrigeration start instruction may also be: and detecting a trigger signal generated after the wireless signal is disconnected. It can be understood that if the electric lunch box needs to be placed in a shielded environment such as a refrigerator or a microwave oven for refrigeration, the terminal may not detect the wireless signal, and therefore, the electric lunch box can be considered to be placed in the refrigerator and start to be refrigerated when the wireless signal is interrupted.

Specifically, detecting the wireless signal disconnection may include: and if the other one of the terminal and the cooking appliance does not receive the returned heartbeat packet after N preset periods M, the disconnection of the wireless signal is judged, wherein N is more than or equal to 3 and less than or equal to 8.

In the present embodiment, as shown in fig. 2, a heartbeat packet is transmitted from the cooking appliance, and the terminal receives the heartbeat packet.

It can be understood that, the cooking appliance sends a heartbeat packet, and the terminal does not receive the heartbeat packet after a predetermined period M, the counter of the control module adds 1, and the initial value of the counter is 0, so that after N predetermined periods M, that is, when the value of the counter reaches N, the heartbeat packet is not received, and the wireless signal interruption is determined. The predetermined period M may be understood as a heartbeat packet period.

In other embodiments, the terminal may periodically poll to detect whether the wireless signal is disconnected; or, the cooking utensil detects the intensity of the wireless signal in real time, and if the intensity of the wireless signal is smaller than a preset threshold value, the disconnection of the wireless signal is judged.

It can be understood that after the refrigeration is finished, the voice prompt device such as the buzzer can be controlled to remind the user, or the information of the refrigeration finish is sent to the user terminal.

Next, the control module of the cooking appliance may control the cooking appliance to enter a predetermined cooking mode, such as a low-sugar rice mode, after receiving the rice-heating instruction: reheating the food materials in the food material to a preset temperature, stopping heating, and then preserving heat.

The present invention also provides a cooking appliance, the specific structure of which has been described in detail in the above description of the cooking appliance, and is not repeated herein for brevity.

According to the control method and the cooking appliance, the prompt can be sent when the timed time reaches the preset refrigerating time t, so that a good refrigerating effect can be achieved, a user can timely know that the refrigerating is finished, and preparation can be made for a cooking mode to be executed so as to achieve a good cooking effect.
