step 604, controlling a low-temperature air blowing device to work according to the reserved cooking signal to generate air to dry food materials to be cooked placed on a filter screen of the cooking appliance;

step 606, timing the working time of the low-temperature air blowing device;

step 608, controlling the low-temperature air blowing device to stop working when the working length reaches a second preset time length;

step 610, timing the reserved time length corresponding to the reserved cooking signal;

step 612, controlling a heating element of the cooking appliance to work when the first preset time length is reached;

step 614, when the temperature of the gas in the inner pot reaches the preset temperature of a temperature control switch of the cooking appliance, controlling a filter screen to put the food to be cooked into the inner pot of the cooking appliance;

the second preset time length is greater than the third preset time length, and the reserved time length is greater than the second preset time length.

When the switch is a temperature control switch, timing is carried out through the reserved time corresponding to the reserved cooking signal, when the second preset time is reached, the heating element of the cooking appliance is controlled to work to heat the inner pot, when the gas temperature in the inner pot reaches the reserved temperature of the temperature control switch of the cooking appliance, the filter screen is controlled to put food to be cooked into the inner pot of the cooking appliance, the food to be cooked is made to be good in quality, rich in nutrition and good in taste by utilizing the dried and fresh food to be cooked, the pursuit of a user for healthy diet is met, the use experience of the user is improved, the satisfaction of the user is improved, the practicability of the reserved function of the cooking appliance is improved, the use range of the reserved function is expanded, the user can use the reserved cooking function safely and safely, the product selling point is improved, and the market competitiveness of the product is improved.

Furthermore, the second preset time is longer than the third preset time, so that the low-temperature air blowing device can be controlled to stop working when the working time of the low-temperature air blowing device reaches the third preset time before the appointment stage is finished and the heating stage is started, the energy is further saved, and the use cost of a user is reduced.

In a specific embodiment, the cooking appliance is an electric cooker, and the user can cook rice by the electric cooker in an appointment mode. In the prior art scheme, the rice is soaked in water in the appointment stage, so that the rice is rich in nutrition and easy to generate bacteria, and even if the rice is not soaked in water, the water activity is high due to water absorption after rice washing, and the bacteria are easy to breed. According to the technical scheme, before the appointment cooking operation is started, proper water is placed in the inner pot, the washed rice is placed on the filter screen, the appointment cooking function is started by a user through the smart phone APP, when the electric rice cooker receives a signal of the appointment cooking function, the low-temperature air blowing device is started to generate hot air of 40-70 ℃, the rice is dried, the low-temperature hot air can not only ensure that the rice is not pasted, but also can blow water, the rice is ensured not to generate bacteria in the appointment process, meanwhile, the rice and the water are separately placed in the inner pot, the phenomenon that the rice is soaked in the water in the appointment stage to breed the bacteria and become sour, smelly and deteriorated is avoided, and the freshness and the sterility of the rice are effectively guaranteed.

Further, when the appointment duration reaches the second preset duration, the heating element is controlled to work to heat the inner pot, the rice is arranged in the filter sieve, the boiling speed of water in the inner pot is high, the temperature rise time is saved, when the temperature in the inner pot rises to the preset temperature of the temperature control switch, the temperature control switch controls the filter sieve to put the rice into the inner pot hot water for cooking, the rice absorbs water at the highest speed due to the water difference of the dried rice, the gelatinization is easier, and the cooking efficiency is improved.

Further, when the second preset time length is reached, the low-temperature air blowing device can be controlled to stop control, so that the low-temperature air blowing device is controlled to stop working when the appointment stage is finished and the heating stage is started, the problem that the low-temperature air blowing device continues working in the heating stage to waste energy is avoided, the energy is effectively saved, the waste is avoided, the use cost of a user is reduced, and the use satisfaction of the user is improved.
