So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
So that the manner in which the features and aspects of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Example one
An embodiment of the present invention provides a control method, where the control method in this example is applied to a cooking appliance having a cooking cavity for containing food materials, as shown in fig. 1, and the control method mainly includes the following steps:
step 101: when the food is detected to be put into the cooking cavity of the cooking appliance, whether a first preset time interval is reached is judged.
In this embodiment, the cooking cavity may be a pot for containing food materials.
Exemplarily, when the cooking appliance has a detachable pot, the cooking cavity refers to the detachable pot of the cooking appliance. For example, an electric cooker or a pressure cooker, etc. has a separable pot, commonly called an inner pot, and then, detecting whether food is put in a cooking cavity means detecting whether food is put in the inner pot.
Exemplarily, when the cooking appliance does not have a detachable pot, the cooking cavity refers to a non-detachable cooking cavity integrated with the cooking appliance main body. For example, in the case of cooking appliances such as an electric baking pan, an electric chafing dish, etc., the cooking cavity means a cooking cavity pot which cannot be separated from the main body of the cooking appliance.
In an optional embodiment, the method for detecting whether food materials are put into a cooking cavity of the cooking appliance comprises the following steps:

and judging whether food materials are put into the cooking cavity of the cooking appliance according to the detection data.
Here, the first sensor includes, but is not limited to, an infrared sensor, a weight sensor, an image sensor.
For example, when the detection data of the infrared sensor indicates that an object exists in the cooking cavity, it is determined that food is put into the cooking cavity.
For another example, when the current weight of the cooking cavity represented by the detection data exceeds a preset weight threshold, it is determined that food materials are put into the cooking cavity. The preset weight threshold may be a net weight value when no food material is put into the cooking cavity of the cooking appliance.
For another example, when the detection data of the image sensor represents that an object image exists in the cooking cavity of the cooking appliance, it is determined that food is put into the cooking cavity. In general, when no food material is placed in the cooking cavity, no object image is acquired.
Therefore, whether food materials are put into the cooking cavity or not can be accurately judged.
In another alternative embodiment, the manner of detecting whether food material is placed in the cooking cavity comprises:
when the situation that the electric cooking appliance is changed from the non-sealing state to the sealing state and the electric cooking appliance is in the power-on standby state is detected, food materials are put into the cooking cavity.
For example, when the pressure cooker is not used and the cooker cover is not closed, the pressure cooker is in a non-sealing state; when the cooker cover is in a closed state, the pressure cooker is in a sealed state. When the cover of the pressure cooker is changed from a non-closed state to a closed state and is in a power-on standby state, under a general condition, the food materials are judged to be put into the cooking cavity of the pressure cooker, and the pressure cooker needs to be used.
Here, the first preset time interval T may be set before the cooking appliance leaves the factory, or may be set by a user according to actual needs of the user or adjusted according to an existing first preset time interval T. For example, the first preset time interval T may be set to 5 minutes, 10 minutes, and so on.
As an optional embodiment, when the food material is detected to be put into the cooking cavity, the method further comprises:
acquiring the storage state of the food material in the current environment;
and adjusting a first preset time interval according to the storage state.
Therefore, the first preset time interval is adjusted according to the storage state, and the first preset time interval can be timely adjusted according to the storage state of the current food, so that the output first reminding message is adaptive to the storage state of the current food.
In a specific embodiment, the acquiring the storage state of the food material in the current environment includes:
acquiring current room temperature parameters;
judging the category of the food material;
obtaining a correlation curve of the storage time and the freshness of the food material under the current room temperature parameter by combining the current room temperature parameter and the food material category;
acquiring a freshness reference value of food materials in the current environment through detection;
combining the freshness reference value with the correlation curve to obtain a freshness guide value;
correspondingly, the adjusting the first preset time interval according to the storage state includes:
and determining a first preset time interval which is adaptive to the freshness guide value according to the freshness guide value.
Therefore, the prompt time is adjusted according to different storage states, information such as the fresh state of the food material at the room temperature, the food material fresh-keeping time period and the like is intelligently prompted to a user, the user can conveniently know the current state of the food material in time, and the operation is carried out according to the current state of the food material.
Step 102: and if the first preset time interval is reached, judging whether a first operation instruction is received or not.
In an optional embodiment, the microcontroller of the cooking appliance detects whether the first preset time interval T is reached, and if so, determines whether the first operation instruction is received.
In an embodiment, the determining whether the first operation instruction is received includes:
judging whether a control panel of the cooking appliance receives a trigger operation for selecting a cooking mode; or
Judging whether the cooking appliance receives an operation instruction sent by first equipment and used for selecting a cooking mode; wherein the first device is a device connectable with the cooking appliance.
Here, the first device may be an input device matched with the cooking appliance, such as an input pen, an input keyboard, and the like. The first device can also be connected with a terminal of the cooking appliance through a network, such as a mobile phone, a tablet personal computer and the like, and when a user sends a first operation instruction on the terminal, the terminal sends the first operation instruction to the cooking appliance so that the cooking appliance executes the first operation instruction.
Generally, the control panel is provided with a start key, a close key, a function selection key, a reservation key, and the like. The function selection key is a cooking type supported by the cooking appliance, such as steaming, boiling, stewing, and the like. It should be noted that the cooking types supported by different cooking appliances may be different.
Step 103: and if the first operation instruction is not received, outputting first prompt information, wherein the first prompt information is used for reminding a user of giving a corresponding instruction operation.
Optionally, the outputting the first prompt information includes at least one of:
outputting first prompt information through the cooking appliance;
sending the first prompt message to first equipment, and outputting the first prompt message by the first equipment; wherein the first device is a device which can be connected with the cooking appliance.
As a specific implementation manner, the outputting the first prompt information includes:
and outputting first prompt information by the cooking appliance.
Optionally, the manner of outputting the first prompt message by the cooking appliance itself includes, but is not limited to, the following:
voice alarm and color change of indicator light.
As a specific implementation manner, the outputting the first prompt information includes:
sending first prompt information to second equipment so as to output the first prompt information by the second equipment; wherein the second device is a device that can be connected with the cooking appliance.
The second device may be the same device as the first device or may be a different device.
Here, when the second device outputs the first prompt information, the output form is adapted to the hardware of the second device.
For example, when the second device is a mobile phone, the manner of outputting the first prompt information may be ringing, vibration, voice prompt, and the like.
Therefore, under the condition that the user forgets to set the appointment operation after the food is discharged, the cooking appliance cannot be in a waiting state all the time due to the fact that the user forgets to trigger the cooking appliance after the food is discharged, the user is reminded to give corresponding indication operation, and the intellectualization and the humanization of the cooking appliance are improved.
Further optionally, when it is detected that food is put into the cooking cavity of the cooking appliance, if the storage state of the food in the current environment is obtained, the first prompt message further includes at least one of the following:
the food fresh-keeping method comprises the steps of fresh state information of food under the current environment and food fresh-keeping time period information.
Further, after the outputting the first prompt message, the method further includes:
judging whether a second operation instruction is received or not;
if a second operation instruction is received, executing corresponding operation according to the second operation instruction;
if the second operation instruction is not received, continuously judging whether the first preset time interval is reached, continuously judging whether the second operation instruction is received when the first preset time interval is reached, and if the second operation instruction is not received, continuously outputting the first prompt message.
Therefore, after the cooking appliance receives the second operation instruction, the first prompt message is not output any more.
Here, the second operation instruction is different from the first operation instruction.
The first operation instruction refers to an operation instruction received by the cooking appliance within a first preset time interval when the user starts to time when food is put into the cooking cavity of the cooking appliance and the first preset time interval is reached.
The second operation instruction refers to an operation instruction received by the cooking appliance after the first prompt message is output.
If the cooking appliance does not receive the second operation instruction, the first prompt information is output once at intervals, and therefore the probability of the user responding to the first prompt information is increased due to the fact that the number of times of outputting the first prompt information is increased.
Further, after the cooking appliance is detected to finish cooking the food material, the method further comprises the following steps:
after a second predetermined time interval has elapsed,
acquiring the weight of the current food material in a cooking cavity of the cooking appliance;
comparing the current food material weight with the food material weight at the end of cooking;
and if the cooking time does not change, outputting second prompt information, wherein the prompt information is used for reminding a user to process the cooked food material.
As an embodiment, when obtaining the weight of the current food material in the cooking cavity of the cooking appliance, the method further includes:
acquiring the freshness and the preservation time period of the food material in the current environment;
and adjusting a second preset time interval according to the freshness and the preservation time period.
Therefore, the prompt time is adjusted according to the real-time fresh storage state, the information such as the fresh state of the food material at the room temperature, the food material fresh-keeping time period and the like is intelligently prompted to the user, and the user can eat the food material with the optimal nutrition and taste.
Fig. 2 shows a cooking mode schematic diagram of the cooking appliance, as shown in fig. 2, wherein the cooking mode of the cooking appliance at least comprises: and (5) cooking immediately and reserving cooking.

Specifically, the food material identification module judges whether food materials exist or not and food material types, static information such as storage time and freshness of different food materials at different temperatures can be obtained by combining the environment temperature detection sensor, and finally a film sensor is combined to obtain a reference value of freshness of the current food material, and information such as different freshness and corresponding storage time is finally informed to a user through the signal prompt module, so that the user can sense the current food material state to make operation judgment.
It should be noted that several sensor modules of the cooking appliance do not necessarily exist at the same time, but at least include 2 modules, one is a food material identification module for judging whether food materials are placed in a cooking cavity of the cooking appliance and the type of the food materials, and the other is a signal prompt module for prompting a user to perform related operations.
The control method can be applied to a cooking appliance with a cooking cavity for containing food materials. For example, the cooking appliance can be an induction cooker, an electric pressure cooker, an electric baking pan, a soybean milk maker, a juice extractor and the like.
According to the control method provided by the embodiment of the invention, when the cooking appliance detects that food materials are put into the cooking cavity of the cooking appliance, whether a first preset time interval is reached is judged; if the first preset time interval is reached, judging whether a first operation instruction is received or not; and if the first operation instruction is not received, outputting first prompt information, wherein the first prompt information is used for reminding a user of giving a corresponding instruction operation. In this way, the cooking appliance detects that food materials are put into the cooking cavity, and if a first operation instruction is not received when the first preset time interval is reached, first prompt information is output; therefore, under the condition that the user forgets to set the appointment operation after the food is discharged, the cooking appliance cannot be in a waiting state all the time due to the fact that the user forgets to trigger the cooking appliance after the food is discharged, the user is reminded to give corresponding indication operation, and the intellectualization and the humanization of the cooking appliance are improved.
Example two
Fig. 3 is a schematic diagram of a first implementation process of a cooking appliance according to an embodiment of the present invention, where the cooking appliance reminds a user of placing food materials and then gives an operation instruction, and as shown in fig. 3, the process includes:
step 301: powering on the cooking appliance, and then executing step 302;

step 304: the cooking appliance judges whether the setting of the fixed time interval T is finished, if so, step 305 is executed; if not, go to step 310;
here, T may be set according to actual conditions. For example, 30 seconds, 50 seconds, etc. may be set.
The T may be set by a manufacturer before the cooking appliance leaves a factory, or may be set by a user according to a use habit of the user or may be adjusted to a set T value.
Step 305: the cooking appliance judges whether an operation instruction is received, if the operation instruction is not received, step 306 is executed; if an operation instruction is received, go to step 309;
step 306: the microcontroller of the cooking appliance outputs a specific driving signal 1 to remind a user of giving an operation instruction, and then the step 307 is carried out;
step 307: the microcontroller of the cooking appliance judges whether the reminding duration t1 is finished, if so, the step 309 is executed; if not, returning to step 306;
step 308: the microcontroller of the cooking appliance stops outputting the specific driving signal 1, prompts a user to give a second operation instruction, and then returns to the step 304;
step 309: the cooking appliance sets a cooking mode according to the operation instruction and then executes step 310;
step 310: the cooking appliance enters an initial standby state.
The method comprises the steps of powering on a cooking appliance, starting a food material identification module, judging whether food materials are placed in a cooking cavity or not, entering an initial standby state if no food materials are placed, if food materials are placed, after a set fixed interval time T is reached, if a user does not perform further functional operation, judging that the user forgets to press down an operation function, outputting a specific driving signal 1 by a microcontroller at the moment, continuing for a time T1, driving the specific driving signal to a prompt module, reminding the user to perform corresponding operation, after the prompt time T1 is reached, stopping outputting the specific driving signal 1 to the prompt module by the microcontroller at the moment, after the set fixed interval time T is reached, if the user still does not perform further functional operation, and repeating the last step.
