Further, the cooking principle of the electric cooker of the present disclosure will be described with reference to fig. 6 to 9:
As shown in fig. 8, the lines in the drawing represent the position of putting rice, water is put in the gap between the inner pot 2 and the steamer 3, when the electromagnetic valve assembly 41 works, under the action of the lifting assembly 33, the through hole 32 under the steamer 3 is sealed by the through hole sealing member 34, so that the steamer 3 keeps a sealed state, when the product is heated, steam is heated from the gap between the steamer 3 and the inner pot 2 and cooks rice in the steamer 3 through the ventilation holes 31 on the side surface of the steamer 3, and the product works for a long time, so that a certain amount of water exists in the steamer 3, and in the sealed state, the starch in the rice can be separated into rice soup in the process of rolling and boiling the rice and the water when the product is heated.
As shown in fig. 9, the electromagnetic valve assembly 41 stops working, so that the lifting assembly 33 and the steamer 3 are opened, at this time, rice soup in the steamer 3 flows into the inner pot 2 through the through hole 32 at the bottom of the steamer 3, rice is separated from rice soup, the starch content of rice is reduced, and the sugar content is reduced.
During the heating process of the product, the electromagnetic valve assembly 41 moves for a plurality of times (the state of fig. 8 and the state of fig. 9 are alternately carried out), so that the contact time of rice and rice soup is thoroughly reduced, and the starch content and sugar content of the rice are reduced.
Fig. 10 is a flowchart illustrating a control method of an electric rice cooker according to an exemplary embodiment, which is applied to the control of the electric rice cooker of any one of the above-described embodiments, as shown in fig. 10, including the following steps S101 to S103,
In S101, the controller controls the heating device to heat the water in the inner pot so as to boil the water and generate water vapor.
In S102, the controller controls the solenoid valve assembly to operate for a first preset period of time to allow the through hole sealing member to seal the through hole, so that boiling water and generated water vapor enter the steamer from the ventilation holes in the side wall of the steamer, and rice in the steamer is rolled, so that starch in the rice is separated into rice soup.
In S103, after the first preset time period is reached, the controller controls the solenoid valve assembly to stop working for a second preset time period, so that the through hole sealing member opens the through hole, and rice soup in the steamer flows into the inner pot from the opened second through hole.
In S104, after the second preset time period is reached, the steps of controlling the operation and stopping the operation of the solenoid valve assembly are cyclically performed.
