In step 51, the cooking program is finished, and the heat preservation is started after the time interval t 1. Wherein the food processor 100 can whip, heat, etc. the food when operating under the cooking program, so that the food is cooked. The main control circuit 211 controls the heating assembly 15 to operate in a heat preservation mode corresponding to the temperature signal according to the temperature signal representing the external environment temperature T generated by the temperature measuring device 25, and starts a heat preservation function. For example, the food processor 100 completes the preparation of the soy milk and boils. The temperature T0 in the cup assembly 10 at this time is the boiling temperature of water, for example 100 degrees celsius. After the interval T1, the temperature T0 within the cup assembly 10 drops to the first temperature T1. Wherein the first temperature T1 is the lowest threshold temperature set in the selected soak procedure. After the heat preservation program is started, when the temperature T0 in the cup assembly 10 drops to the first temperature T1, the main control circuit 211 controls the heating assembly 15 to start heating. When the external ambient temperature T is different, the duration of T1 is different.

In step 52, heating at the set low power for a first time is continued for a time period t 3. Heating to a second temperature T2, wherein the second temperature T2 is the highest temperature threshold set in the selected heat preservation program; setting the low power to be 1/20-1/2 of the rated power of the heating assembly 15, and setting the optimal heating power to be 1/5-1/3 of the rated power of the heating assembly 15; the time period t3 may be 1 second to 90 seconds, for example 10 seconds.

In step 53, the first heating is stopped, and the heating is stopped for a period of time t 4. Until the temperature T0 within the cup assembly 10 drops to the first temperature T1. In step 54, heating at the set low power for a second time is continued for a time period T5 until the temperature T0 in the cup assembly 10 rises to a second temperature T2. In step 55, the second heating is stopped for a period of time t 6. Until the temperature T0 within the cup assembly 10 drops to the first temperature T1. In step 56, the nth heating is performed at a predetermined low power for a heating time period t2n + 1. Until the temperature T0 within the cup assembly 10 rises to a second temperature T2. In step 57, the nth heating is stopped for a period of time t2n + 2. Until the temperature T0 within the cup assembly 10 drops to the first temperature T1. Thus, the incubation time is terminated until the selected incubation procedure is completed.

N in the above control method 50 is a natural number. Setting the total heat-preservation time length t2, the total heat-preservation time length t2 is: the heating is stopped from the first time at the set low power to the nth time, and then stopped for the total time period of t2n + 2. When the external ambient temperature T is different, the total holding time period T2 may be different. For example, when the external ambient temperature T is between-5 degrees celsius and 0 degrees celsius, the total incubation time T2 is between 5 minutes and 180 minutes. When the external ambient temperature T is between 0 and 5 degrees celsius, the total duration T2 of incubation is between 15 and 120 minutes. So, cooking machine 100 can select the heat preservation procedure that corresponds according to external environment temperature, adjusts the heat preservation temperature of food in the cup subassembly 10 to can provide the food of the suitable temperature of user in different seasons, make the user when tasting food, the temperature of food is unlikely to supercooling or overheated, promotes user experience.
