Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a heat preservation method, apparatus, air fryer, and storage medium for an air fryer. Background Technology

[0002] An air fryer is a machine that uses air to "fry" food. It mainly uses air to replace the hot oil in a frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, giving the ingredients an effect similar to deep-frying.

[0003] Existing air fryers often have limited functionality, offering only basic heat preservation. For example, patent CN214712148U discloses an air fryer with a heat preservation chamber, which includes an active heat preservation component electrically connected to the main unit and housed within the heat preservation chamber. This active heat preservation component is a device that converts electrical energy into heat energy, such as a PTC heating element or heating wire. While this patent allows the active heat preservation component to keep processed food warm, the heat preservation function is relatively simple, only allowing switching between on and off heat preservation modes, which cannot meet the heat preservation needs of more scenarios. Summary of the Invention

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a heat preservation method, device, air fryer and storage medium for an air fryer that can meet the heat preservation needs of more scenarios.

[0012] Furthermore, the number of the terminals is multiple;

[0013] The execution of the predetermined operation matching the triggering condition includes:

[0014] The system searches for authenticated terminals using short-range communication units and / or searches for online authenticated terminals within a local area network, and determines whether there are any terminals that meet the criteria, thereby obtaining a first determination result.

[0015] If the first determination result is yes, issue an audible alarm and / or push information to the terminal that meets the conditions;

[0016] If the first determination result is negative, information is pushed to the specific terminal or information is pushed to each terminal in a predetermined order.

[0017] Furthermore, the element is time, and the corresponding triggering condition is: the interval between the current time and the time when food processing is completed or the interval between the current time and the time when the same type of operation was last performed reaches a preset duration;

[0018] The execution of the predetermined operation matching the triggering condition includes:

[0019] Controlling the operation of the heating device to heat food at high temperatures and sterilize it.

[0020] Furthermore, the execution of the predetermined operation matching the triggering condition includes:

[0021] When the heat preservation time approaches the predetermined time, the server is requested to obtain the location data of the terminal.

[0022] Determine whether the location data of the terminal is within the range where the meal can be picked up in a timely manner, and obtain a second determination result;

[0023] If the second determination result is yes, a meal pickup reminder message is pushed to the terminal through the network connection;

[0024] If the second determination result is negative, the insulation setting information is pushed to the terminal through the network connection, and after the terminal returns the second setting instruction, the insulation can continue or stop according to the second setting instruction.

[0025] Furthermore, the method also includes:

[0026] During the heat preservation process, record the temperature data.

[0027] The temperature data is shared with the terminal via the network connection.

[0028] Furthermore, when the terminal is a terminal that has never been connected before, establishing a network connection with the terminal through the server includes:

[0029] Receive the terminal's binding information through the network connection;

[0030] The information of the terminal is acquired and stored locally.

[0031] The heat preservation device of the air fryer includes:

[0032] A connection unit, used to establish a network connection with the terminal via a server;

[0033] The instruction acquisition unit is used to acquire a first setting instruction sent by the terminal through the network connection, the first setting instruction including a predetermined temperature and a predetermined time.

[0048] Furthermore, in the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0049] Example 1

[0050] This application provides a method for keeping an air fryer warm, which can be applied to, for example... Figure 1 In the application environment shown, Figure 1The system includes an air fryer 110, a server 120, and a terminal 130. The terminal 130 can take the form of a mobile phone, tablet, computer, smart TV, wearable device, smart speaker, or other similar device. The terminal 130 can connect and communicate with the server 120 via its underlying system functions or a pre-installed app. The air fryer 110 can also connect and communicate with the server 120 via the network. Thus, the server 120 acts as a bridge for communication between the air fryer 110 and the terminal 130. The server 120 can be a standalone server or a server cluster consisting of multiple servers.

[0051] In one embodiment, such as Figure 2 As shown, a method for keeping an air fryer warm is provided, the method comprising: Figure 1 The method is implemented by the control unit of the air fryer 110, and includes the following steps S201-S203:

[0052] Step S201: Establish a network connection between the server 120 and the terminal 130;

[0053] Step S202: Obtain a first setting instruction sent by terminal 130 through the network connection. The first setting instruction includes a predetermined temperature and a predetermined time.

[0054] In this step, the content of the first setting instruction is not limited to the aforementioned predetermined temperature and predetermined time, but may also include other information, such as timestamps, other instruction content, etc.

[0055] Step S203: After frying the food, keep the food warm at the predetermined temperature and start a countdown for the predetermined time.

[0056] In the above steps, users can remotely set the preset temperature and time via terminal 130, allowing them to retrieve food at the appropriate temperature before the preset time expires, thus improving the user experience. The control unit maintains the food at the set temperature during the first time period before the countdown begins. During the second time period after the countdown, it performs a secondary processing of the food using a preset temperature pattern (set according to the type of food; the control unit can pre-store temperature patterns for processing various types of food and call the corresponding temperature pattern during processing). This ensures that users can retrieve food with a better flavor when the countdown ends, making the taste similar to freshly fried food. The length of the second time period is determined by the time required for the secondary processing of the food, and the total duration of the first and second time periods is the same as the preset time.

[0057] Preferably, such as Figure 3 As shown, the method further includes the following steps S301-S303:

[0058] Step S301: Determine whether the element or combination of elements meets the corresponding triggering condition; wherein, the element includes one or more of the following elements: time, food temperature, terminal location information, and terminal login status;

[0059] In this step, time can be a time interval (the interval between the current time and the time when food processing is completed, or the interval between the current time and the time when the same type of operation was last performed), or it can be the total duration of heat preservation. Terminal location information can be specific location information or location range information. For example, if both terminal 130 and air fryer 110 have short-range communication units such as Bluetooth, and air fryer 110 can search for the Bluetooth ID of terminal 130 via Bluetooth, it means that terminal 130 is within a circular location range centered on air fryer 110 and with a radius equal to the Bluetooth communication limit distance. Terminal login status includes online and offline states.

[0060] Step S302: When an element or combination of elements reaches the corresponding triggering condition, a predetermined operation matching the triggering condition is executed.

[0061] In this step, the pre-defined operations include: pushing reminder information to the terminal 130, pushing the operation interface, and temperature control. The air fryer 110 can push reminder information to the terminal 130 via MQTT / TCP.

[0062] In one embodiment, there are multiple terminals 130, and all terminals 130 have previously established a connection with the air fryer 110 through an access process, so that these terminals 130 are authenticated terminals 130 for the air fryer 110.

[0063] When the predetermined operation involves conveying information to the user, such as Figure 4 As shown, the execution of the predetermined operation matching the triggering condition in step S302 above includes the following steps S401-S403:

[0064] Step S401: Search for the authenticated terminal 130 through the short-range communication unit and / or search for the online authenticated terminal 130 in the local area network, and determine whether there is a terminal 130 that meets the conditions, and obtain the first determination result;

[0065] In this step, the short-range communication units can be communication modules that communicate based on existing technologies such as Bluetooth, WIFI, RFID, and UWB, or they can be newly emerging short-range communication modules in the future, preferably Bluetooth modules.

[0066] Step S402: When the first judgment result is yes, issue an audible alarm and / or push information to the terminal 130 that meets the conditions, while ignoring other information that does not meet the conditions;

[0067] In this step, when the control unit of the air fryer 110 can find the authenticated terminal 130 through the short-range communication unit, or can find the authenticated terminal 130 within the local area network, it indicates that the found terminal 130 is close to the air fryer 110 and the user corresponding to that terminal 130 is online. Therefore, it is preferable to push information to these terminals 130, so that the users of these terminals 130 can perform operations such as picking up food from the air fryer 110 in a timely manner. In addition, in this step, in a home scenario, an audible alarm can be issued first. If there is no response within the first time limit after the audible alarm is issued, information can then be pushed to the qualified terminals 130.

[0068] Step S403: If the first determination result is negative, push information to the specific terminal 130 or push information to each terminal 130 in a predetermined order.

[0069] In this step, pushing information to a specific terminal 130 can be done by pushing information to all terminals 130 or to a portion of designated terminals 130; the predetermined order is set by the user in advance.

[0070] Through the above steps S401-S403, we can notify only the nearest terminal 130 as much as possible, so that users of nearby terminals 130 can pick up their meals in a timely manner, effectively avoiding disturbing all users of terminals 130.

[0071] In one embodiment, the element is time, and the corresponding triggering condition is: the interval between the current time and the time when food processing is completed or the interval between the current time and the time when the same type of operation was last performed reaches a preset duration.

[0072] The execution of the predetermined operation matching the triggering condition in step S302 above includes:

[0073] Controlling the operation of the heating device to heat food at high temperatures and sterilize it.

[0074] In one embodiment, such as Figure 5 As shown, the execution of the predetermined operation matching the triggering condition in step S302 above includes the following steps S501-S504:

[0075] Step S501: When the heat preservation time is close to the predetermined time, that is, the difference between the heat preservation time and the predetermined time is less than the preset duration, the server 120 requests the location data of the terminal 130.

[0076] Step S502: Determine whether the location data of the terminal 130 is within the location range where the meal can be picked up in time, and obtain a second determination result;

[0077] Step S503: When the second judgment result is yes, push the meal pickup reminder information to the terminal 130 through the network connection;

[0078] Step S504: When the second judgment result is negative, heat preservation setting information is pushed to the terminal 130 through the network connection, and after the terminal 130 returns the second setting instruction, heat preservation is continued or stopped according to the second setting instruction; if no feedback information is received from the terminal 130 within the set time, heat preservation is stopped or heat preservation is continued according to the data of the first setting instruction.

[0079] In this step, the second setting instruction returned by terminal 130 may be a stop heat preservation instruction, or a similar first setting instruction that includes a predetermined temperature and a predetermined time.

[0080] In the above steps S501-S504, by obtaining the user's location data and pushing appropriate information accordingly, the pushed information is more targeted and can save the user's time.

[0081] In one embodiment, the method further includes the following steps S601-S602:

[0082] Step S601: During the heat preservation process, record the heat preservation temperature data;

[0083] In practice, temperature information corresponding to a given moment can be saved at fixed time intervals.

[0084] Step S602: Share the temperature data with the terminal 130 through the network connection.

[0085] In this step, the air fryer 110 can first send the temperature data to the server 120. The server 120 saves the temperature data. When the terminal 130 needs to query the temperature data, it sends a request command to the server 120. The server 120 feeds back the corresponding temperature information to the terminal 130 according to the request command.

[0086] In one embodiment, when the terminal 130 is a terminal 130 that has never been connected before, the establishment of a network connection with the terminal 130 through the server 120 in step S201 above includes the following steps S701-S702:

[0087] Step S701: Receive the binding information of the terminal 130 through the network connection;

[0088] In this step, terminal 130 calls the binding interface through the system interface to bind the device. The binding operation is generally completed in server 120. After binding is completed...

[0089] Step S702: Obtain the information of the terminal 130 and store it locally.
