Specifically, according to the operation control method of the present invention, it is first judged whether the appointment is an over-long appointment according to the appointment duration, if not, the normal appointment cooking mode is used, if the appointment is judged to be an over-long appointment, then the cooking environment temperature is judged, if the cooking environment temperature is judged to be a high temperature, the over-long appointment mode is started, otherwise, the normal appointment cooking mode is started. In the super-long reservation mode, at the last stage of cooking, if the temperature in the cooking container is judged to be too low, heating is carried out according to a certain power.

Taking rice cooking as an example, the ultra-long appointment rice cooking has the following two realization modes:

1) firstly, determining the rice deterioration threshold time t under the high-temperature environment according to experimental data₂If the redundant time coefficient alpha is given to ensure the health performance of cooking, cooking is started after the accumulated time after reservation meets the formula (1).

t₁≥t₂-α (1)

The normal cooking and stewing time T is set at the stewing stage of the super-long reservation mode₁Is changed into T₂Wherein T is₂As shown in equation (2):

T₂＝T-{(t₂-α)+t₀} (2)

in order to prevent the dish from cooling for too long in the stewing waiting period, a heating time t at the early stage of cooking ending is determined₃The heating of the meal is started when the reservation accumulated time at this stage satisfies the formula (3).

T-t₂+α≥t₃ (3)

The power for heating the meal to prevent the meal from becoming cold is P₁The value range is shown in formula (4):

wherein, t₀A preset cooking time required for completing a certain item of cooking; t is t₁The cooking time is waited for after appointment; t is t₂The deterioration threshold time of the rice; t is t₃The preset residual time before cooking is finished is prevented for long-time stewing; t is the reserved time length, wherein the value range of T is as follows: t is more than or equal to 24 and more than or equal to T₂；T₁The stewing waiting time in the normal reservation cooking mode is set; t is₂For a stewing waiting time in an ultra-long reservation mode, wherein T₂The value range is (T-T)₂)≥T₂Not less than 0; alpha is a redundant time coefficient introduced for ensuring the health performance of the long-time reservation cooking, and the value range is as follows: (T-T)₀) Alpha is more than or equal to 0, and P is the power during full-power heating; p₁The preset heating power is used for preventing the dishes from cooling after the appointment of a long time in the later period.

2) Adjusting the cooking time, starting cooking after the accumulated time after the appointment meets the formula (1), and simultaneously adjusting the cooking time to be T-T₂+α。

Example four:

according to an embodiment of the present invention, there is also provided a computer-readable storage medium having stored thereon a computer program which, when executed, performs the steps of: responding to the acquired appointment duration and the cooking environment temperature, and determining whether to enter an overlength appointment mode; in the case where it is determined that the ultra-long reservation mode is entered, after the elapse of the cooking waiting time period is detected, control is performed to start execution of the cooking operation, wherein the corresponding cooking waiting time period is determined according to the cooking environment temperature.

Wherein, the relation among the reservation duration, the waiting cooking duration and the material deterioration threshold time can be defined as: t is more than or equal to T for 24h₂，t₁≥t₂- α, T is reservedLong, t₁For waiting for cooking time, t₂Is the material deterioration threshold time, alpha is the redundancy time coefficient, (T-T)₀)≥α≥0，t₀Is a preset cooking time.

T-t₂+α≥t₃

wherein, t₃Is a preset remaining time.

In any of the above embodiments, preferably,

wherein, P₁P is the full cooking power for the preset cooking power.

The technical scheme of the invention is explained in detail in the above with reference to the accompanying drawings, and the invention provides an operation control method, an operation control device, a cooking appliance and a computer readable storage medium, wherein under the cooking conditions of long reservation time and high cooking environment temperature, the risk of deterioration of cooked food exists, the ultra-long reservation mode is set, and the cooking waiting time is determined according to the real-time cooking environment temperature, so that the food in the cooking environment temperature enters a cooking state before deterioration (i.e. bacterial growth) occurs, the probability of deterioration of the cooked food is reduced, the probability of the food after cooking is reduced, and the use requirement of the food cooked in the long-time reservation mode is ensured.
