The working stages of the electric rice cooker in the cooking mode include, in chronological order, a preheating stage, a heating stage, a baking stage and a flavoring stage. It should be noted that, in an embodiment of the present invention, the first heating component, the second heating component and the third heating component may be composed of one or more heating elements, and the heating elements may be thermal resistance wires, electric heating tubes, etc.

[0055] The method may specifically include the following steps:

[0056] Step 101, when the rice cooker is in a first working stage, controlling the first heating component and the second heating component to heat.

[0057] In actual application, when the user selects the salt-baked chicken cooking function on the rice cooker, the rice cooker enters the cooking mode. When the rice cooker is in the first working stage, the first heating component and the second component are controlled to heat, that is, heating is performed through the side and the bottom.

[0058] In an embodiment of the present invention, the first working stage includes a preheating stage, a heating stage and a baking stage, and when the rice cooker is in the first working stage, controlling the first heating component and the second heating component to heat includes:

[0059] When the rice cooker is in the preheating stage, controlling the first heating component and the second heating component to heat at a first duty cycle;

[0060] When the electric rice cooker is in the heating stage, controlling the second heating component and the first heating component to heat at a second duty cycle;

[0061] When the rice cooker is in the baking stage, the second heating component and the first heating component are controlled to heat at a third duty cycle.

[0062] Specifically, the first working stage may include a preheating stage, a heating stage, and a baking stage. That is, when the electric rice cooker is in the preheating stage of the first working stage, the first heating component and the second heating component may be controlled to heat at a first duty cycle; when the electric rice cooker is in the heating stage of the first working stage, the second heating component and the first heating component may be controlled to heat at a second duty cycle; when the electric rice cooker is in the baking stage of the first working stage, the second heating component and the first heating component may be controlled to heat at a first duty cycle.

[0063] It should be noted that when the rice cooker is in the first working stage, it first enters the preheating stage, and after the preheating stage, it enters the heating stage, and after the heating stage, it enters the baking stage.

[0064] In an embodiment of the present invention, controlling the first heating component and the second heating component to heat with a first duty cycle includes:

[0065] Controlling the first heating component and the second heating component to heat to a first preset temperature at the first duty cycle;

[0066] Maintain the first preset temperature interval for a first preset time period; wherein, the first duty cycle is A1:A2, A1 and A2 are both positive integers, A1>A2, and the first preset temperature interval includes the first preset temperature.

[0067] Specifically, when the rice cooker is in the preheating stage in the first working stage, the first heating component and the second heating component can be controlled to heat to a first preset temperature with a first duty cycle, and the first preset temperature interval is maintained for a first preset time period.

[0068] Among them, the first duty cycle of the first heating component and the second heating component can be A1:A2, A1 is the duty cycle of the first heating component, A2 is the duty cycle of the second heating component, A1 and A2 are both positive integers, and A1>A2.

[0069] Further, the first preset temperature interval includes the first preset temperature. That is, after the temperature is heated to the first preset temperature, the temperature can be maintained at about the first preset temperature until entering the heating stage in the first working stage.

[0070] During the preheating stage, the heating components on the sides and bottom are heated through a first duty cycle, with the sides heated mainly and the bottom heated as a supplement, so that the temperature inside the rice cooker can be evenly increased, avoiding uneven temperature inside the rice cooker caused by heating only separately.

[0071] In an embodiment of the present invention, controlling the second heating component and the first heating component to heat with a second duty cycle includes:

[0072] The second heating component and the first heating component are controlled to heat to a second preset temperature not lower than the second preset temperature with the second duty cycle; wherein the second duty cycle is B1:B2, B1 and B2 are both positive integers, and B1>B2.

[0073] Specifically, when the rice cooker is in the heating stage in the first working stage, the second heating component and the first heating component can be controlled to heat to no less than the second preset temperature with the second duty cycle. For example, the second preset temperature is K1, then in the heating stage, the second heating component and the first heating component can be controlled to heat to no less than K1 with the second duty cycle.

[0074] The second duty ratio of the second heating component and the first heating component can be B1:B2, where B1 is the duty ratio of the second heating component, B2 is the duty ratio of the first heating component, B1 and B2 are both positive integers, and B1>B2. After heating to a temperature not lower than the second preset temperature, the temperature can be maintained not lower than the second preset temperature until entering the baking stage in the first working stage.

[0075] During the heating stage, the heating components at the bottom and sides are heated through a second duty cycle, with the bottom heating as the main function and the sides heating as the auxiliary function. This allows the temperature inside the rice cooker to continue to rise, reaching a state close to producing steam, which not only accelerates the cooking of food but also produces aroma at the same time.

[0076] In the embodiment of the present invention, controlling the second heating component and the first heating component to heat with a third duty cycle includes:

[0077] Controlling the second heating component and the first heating component to heat to a second preset temperature range at the third duty cycle;

[0078] The second preset temperature range is maintained for a second preset time period; wherein the third duty ratio is C1:C2, C1 and C2 are both positive integers, C1 <C2。

[0079] Specifically, when the rice cooker is in the baking stage in the first working stage, the second heating component and the first heating component can be controlled to heat with a third duty cycle. When the temperature in the rice cooker belongs to the second preset temperature range, the second preset temperature range is maintained for a second preset time period.

[0080] The first duty ratio of the second heating component and the first heating component can be C1:C2, where C1 is the duty ratio of the second heating component, C2 is the duty ratio of the first heating component, and both C1 and C2 are positive integers, and C1 <C2。

[0081] That is, after being heated to a temperature within the second preset temperature range, the second preset temperature range may be maintained for a second preset time period until entering the second working stage.

[0082] During the baking stage, the bottom and side heating components are heated through a third duty cycle, with the side heating as the main and the bottom heating as the auxiliary. This can not only accelerate the cooking of food, but also avoid the burning phenomenon caused by excessive heating of the bottom.

[0083] Step 102, when the rice cooker is in the second working stage, controlling the third heating component to heat.

[0084] After the first working stage of the rice cooker is finished, the second working stage can be entered. At this time, the third component can be controlled to heat, that is, heating is performed through the top.

[0085] In an embodiment of the present invention, when the electric cooker is in the second working stage, controlling the third heating assembly to heat includes:

[0086] When the rice cooker is in the second working stage, controlling the third heating component to heat to a temperature not lower than a third preset temperature at a preset time ratio;

[0087] Maintain the third preset temperature interval until the end; wherein the preset time ratio is D1:D2, D1 and D2 are both positive integers, D1 is the heating time, D2 is the heating stop time, and the third preset temperature interval includes the third preset temperature.

[0088] Specifically, the second working stage may be a flavoring stage, and when the electric rice cooker is in the flavoring stage, the third heating component may be controlled to heat to a temperature not lower than a third preset temperature at a preset time ratio. For example, if the third preset temperature is K2, then in the flavoring stage, the third heating component may be controlled to heat to a temperature not lower than K2 at a preset time ratio.

[0089] Among them, the preset time ratio is D1:D2, D1 and D2 are both positive integers, D1 is the heating time of the third heating component, and D2 is the stopping heating time of the third heating component.

[0090] Further, the third preset temperature interval includes the third preset temperature. That is, after the temperature is heated to the third preset temperature, the temperature can be maintained at about the third preset temperature until the cooking is finished.

[0091] In the second working stage, the heating component on the top heats the food for a preset time ratio, so that the appearance of the food is intact and undamaged. Not only does the color of the food become bright yellow and look good, but it also stimulates the aroma of the food itself.

[0092] In an embodiment of the present invention, the electric rice cooker includes a cooker body, a first heating component, a second heating component and a third heating component, wherein the first heating component is located at the side of the cooker body, the second heating component is located at the bottom of the cooker body, and the third heating component is located at the top of the cooker body. When the electric rice cooker is in the first working stage, the first heating component and the second heating component are controlled to heat; when the electric rice cooker ends the first working stage and enters the second working stage, the third heating component is controlled to heat. In this way, different heating components are used for heating in different working stages, thereby realizing intelligent cooking of salt-baked chicken by combining heating at the top, the side and the bottom, which can not only ensure that the temperature in the electric rice cooker rises evenly, but also can stimulate the aroma of the food itself while quickly cooking the food, and can also ensure that the appearance of the food is intact and undamaged, thereby improving the appearance of the food.

That is to say, after the temperature is heated to the first preset temperature, the temperature can be maintained at about the first preset temperature until entering the heating stage in the first working stage.

[0111] During the preheating stage, the heating components on the sides and bottom are heated through a first duty cycle, with the sides heated mainly and the bottom heated as a supplement, so that the temperature inside the rice cooker can be evenly increased, avoiding uneven temperature inside the rice cooker caused by heating only separately.
