Abstract

Provided is a method and device for an electronic cooker to control heat preservation. The method includes: acquiring holding temperature data for a food; predicting serving time point data for the food; acquiring serving temperature data for the food at a time point indicated by the serving time point data; determining time point data of terminating the heat preservation for the food in accordance with the serving time point data, the serving temperature data, and the holding temperature data; and terminating the heat preservation for the food at a time point indicated by the time point data of terminating the heat preservation.

Claims

1. A method for controlling heat preservation for an electronic cooker, wherein the electronic cooker includes a processor, and the method is performed by the processor and comprises:

acquiring holding temperature data for a food;

predicting serving time point data for the food;

acquiring serving temperature data for the food at a time point indicated by the serving time point data;

determining current environment temperature data;

determining a temperature changing period in accordance with the holding temperature data, the serving temperature data, the environment temperature data, and an insulation parameter of an inner tank of the electronic cooker, the temperature changing period being a difference between the time point indicated by the serving time point data and a time point indicated by time point data of terminating the heat preservation;

determining the time point data of terminating the heat preservation in accordance with the temperature changing period and the serving time point data; and

terminating the heat preservation for the food at a time point indicated by the time point data of terminating the heat preservation.

2. The method according to claim 1, further comprising:

acquiring time point data of terminating cooking for the food and temperature data of terminating cooking for the food at a time point indicated by the time point data of terminating cooking;

determining time point data of initiating the heat preservation for the food in accordance with the time point data of terminating cooking, the temperature data of terminating cooking, and the holding temperature data; and

initiating the heat preservation for the food at a time point indicated by the time point data of initiating the heat preservation.

3. The method according to claim 1, further comprising:

adjusting a temperature for the food at the time point indicated by the time point data of terminating the heat preservation, such that the food is at the serving temperature at the time point indicated by the serving time point data after the temperature for the food is adjusted.

4. The method according to claim 1, wherein predicting the serving time point data for the food comprises at least one of:

predicting the serving time point data in accordance with information on a historical serving record comprising a time point of opening the electronic cooker after each time point of terminating cooking recorded in advance;

or

taking a time point in a current date that corresponds to the time point of opening the electronic cooker after the last time point of terminating cooking as the serving time point data.

5. The method according to claim 1, wherein predicting the serving time point data for the food comprises:

acquiring information on a route along which a user travels back to a residence;

acquiring information on a transportation mode by which the user travels back to the residence;

acquiring information on a traffic condition of the route along which the user travels back to the residence;

predicting time point data when the user arrives at the residence in accordance with the information on the transportation mode and the information on the traffic condition; and

taking the time point data when the user arrives at the residence as the serving time point data.

6. The method according to claim 5, wherein acquiring the information on the route along which the user travels back to the residence comprises:

receiving information on a current position of the user sent from a terminal;

acquiring information on a position of the residence of the user, the residence being a place where the electronic cooker is located; and

determining the information on the route along which the user travels back to the residence in accordance with the information on the current position of the user and the information on the position of the residence of the user.

7. The method according to claim 1, wherein acquiring the serving temperature data for the food at the time point indicated by the serving time point data comprises at least one of:

taking serving temperature data for the food at a time point of opening the electronic cooker after the last time point of terminating cooking as the serving temperature data;

taking preset recommended temperature data for the food as the serving temperature data;

or

inquiring a preset correspondence between age ranges and temperatures in accordance with an age range to which the user belongs to obtain temperature data corresponding to the age range to which the user belongs, and determining the temperature data corresponding to the age range to which the user belongs as the serving temperature data.

8. The method according to claim 1, wherein acquiring the holding temperature data for the food comprises:

receiving a name inputting instruction for indicating a food name;

determining target holding temperature data corresponding to the food name indicated by the name inputting instruction in accordance with the name inputting instruction and a preset holding temperature correspondence between food names and holding temperatures for the foods; and

taking the target holding temperature data as the holding temperature data.
