Wherein the control board of the heating appliance 100 may be powered by its built-in power supply 113.

In the present embodiment, the rice in the heating appliance 100 may be subjected to the sugar-reducing treatment by means of refrigeration by means of the heating appliance 100 and the refrigeration apparatus 200. Specifically, after cooked rice is usually placed in the heating device 100, if a user needs low-sugar rice, the heating device 100 may be placed in the refrigerator 200, and after the refrigeration is finished, the heating device 100 may be removed from the refrigerator 200, so that the low-sugar rice is obtained.

It will be understood that the heating appliance 100 may be placed in particular in a refrigerating compartment of the refrigerating device 200, the temperature of which is preferably set below 5 ℃, for example the temperature of the refrigerating compartment may be set below 3 ℃.

Since the cooked rice after cold storage needs to be re-heated for consumption and the resistant starch content is reduced by heating, a control method is also provided in this embodiment, as shown in fig. 5 and 6, to increase the resistant starch content to the maximum extent while allowing the food to reach a more palatable temperature.

Specifically, as shown in fig. 5, the control method includes:

As shown in fig. 4, the heating appliance 100 of the present embodiment is further provided with a temperature detection module 160 and a control module 150, wherein the temperature detection module 160 can detect the temperature in the accommodating cavity of the heating appliance 100. For example, the temperature detection module 160 may be disposed at the top, side, or bottom of the receiving chamber to effectively detect the temperature within the receiving chamber. It can be understood that the heating module 140 and the temperature detecting module 160 are both electrically connected to the control module 150, and the control module 150 can receive the temperature information detected by the temperature detecting module 160 to control the heating module 140 to heat the inner container, so as to better perform the cooking function. In the present embodiment, the built-in power supply 113 is electrically connected to the control module 150 and can supply power to the control module 150.

Furthermore, when the heating appliance 100 receives a heating command from a user, the initial temperature in the receiving cavity is detected by the temperature detecting module 160. Wherein, when the initial temperature in the accommodating cavity is less than or equal to the first preset temperature value T₁At this time, the rice in the heating appliance 100 is the rice just after the cold storage treatment, and at this time, the rice needs to be heated in the first heating mode, so that the food reaches a relatively palatable temperature, the content of resistant starch is increased to the maximum extent, the low-sugar effect of the rice is ensured, and the cooking quality is improved.

If the initial temperature in the containing cavity is greater than a first preset temperature value T₁It means that the rice in the heating appliance 100 is the normal rice in the room temperature environment at the present time, and at this time, the rice can be heated in the second heating mode.

Preferably, the nominal power P of the heating module 140_{Rated value}May be selected in the range of 100W to 600W. More preferably, the nominal power P of the heating module 140_{Rated value}The value range of (a) may be selected in the range of 200W to 300W.

In the present embodiment, heating the accommodation chamber in the first heating mode includes:

at a first predetermined power P₁Heating the accommodating cavity with a first predetermined power P₁At one-half rated power P_{Rated value}To fourThree-thirds rated power P_{Rated value}Is selected to heat the temperature of the containing cavity to a second preset temperature value T₂After that, the heating was stopped.

For example, in the present embodiment, the rated power P of the heater module 140_{Rated value}May be equal to 200W, the first predetermined power P₁150W. Of course, in other embodiments, the first predetermined power P₁Other values are possible, for example, the first predetermined power may be equal to 100W.

Preferably, the second predetermined temperature value T₂T is more than or equal to 40 DEG C₂The temperature is selected within the range of less than or equal to 90 ℃. More preferably, the second predetermined temperature value T₂T is not more than 50 DEG C₂The temperature is selected within the range of less than or equal to 80 ℃. E.g. T₂＝50℃。

With the above arrangement, the first heating mode is suitable for the refrigerated low-sugar rice, and in the first heating mode, the power is less than the rated power P_{Rated value}Heats the rice and heats the rice to a second predetermined temperature value T₂The method not only can enable food to reach a palatable temperature, but also can maximally retain the content of resistant starch, and can prevent the problem of rice gelatinization caused by overhigh local temperature of the rice.

In the control method of the present embodiment, the temperature in the housing chamber is heated to the second predetermined temperature value T₂Then, when the duration of stopping heating reaches the heating stopping duration t_StopThereafter, the temperature of the whole of the cooked rice is substantially uniform. At this time, the heating appliance 100 can control the heating module 140 to lower the third predetermined power P₃Heating the holding cavity with a third predetermined power P₃At less than or equal to one-quarter of rated power P_{Rated value}Is selected such that the temperature of the receiving chamber is maintained at a third predetermined temperature value T₃And a fourth predetermined temperature value T₄In the meantime. When the temperature of the accommodating cavity is at a third preset temperature value T₃And a fourth predetermined temperature value T₄Of a first predetermined duration t₁Thereafter, the heating module 140 is controlled to stop heating, and the first heating mode heating process ends. First heatingThe modular heating process is ended and the heating appliance 100 may enter a keep warm phase.

Wherein the heating stop time period t_StopCan be t is more than or equal to 0.5_StopThe time is selected within the range of less than or equal to 8 minutes. More preferably, the heating is stopped for a time period t_StopCan be within 1 ≦ t_StopThe time is less than or equal to 3 minutes. E.g. stop heating period t_Stop2 minutes.

As an implementation, when the heating module 140 is at the third predetermined power P₃Heating to raise the temperature inside the accommodating cavity to the fourth preset temperature value T₄Immediately stopping heating, gradually reducing the temperature in the accommodating cavity, and reducing to a third preset temperature value T₃Then, the heating module 140 is operated at a third predetermined power P₃Heating the inner container to raise the temperature inside the holding cavity again, and repeating the steps to maintain the temperature inside the holding cavity at the third preset temperature value T₃And a fourth predetermined temperature value T₄In the meantime.

Preferably, in the present embodiment, the third predetermined temperature value T₃And a fourth predetermined temperature value T₄The relationship between them is: t is₄＝T₃+2 ℃. Of course, in other embodiments, the difference between the fourth temperature value and the third temperature value may be other values, such as T₄＝T₃+5℃。

Furthermore, a third predetermined temperature value T₃The value of (A) is in the range of 40 to 90 ℃. More preferably, the third predetermined temperature value T₃Is in the range of 50 to 80 ℃, for example, in the present embodiment, T₃＝70℃，T₄＝72℃。

Therefore, the local temperature of the rice is further prevented from being too high, so that the heat can be uniformly transferred among the rice at each part, and the cooking effect is improved.

Preferably, the first predetermined duration t₁T can be less than or equal to 8 minutes₁The time is selected within the range of less than or equal to 15 minutes. E.g. t₁10 minutes.

Next, the control method of the present embodiment is described in detail, and heating the accommodating chamber in the second heating mode may specifically include:

From the foregoing, it can be seen that when the initial temperature in the accommodating cavity is higher than the first predetermined temperature value T₁It means that the rice in the heating appliance 100 is the normal rice in the room temperature environment, and at this time, the rice can be heated at a higher heating power in the second heating mode.

In the second heating mode, the heating module 140 may be at a second predetermined power P₂The inner container 111 is continuously heated, so that the temperature in the accommodating cavity continuously rises until the temperature in the accommodating cavity reaches a fifth preset temperature value T₅And then the heating is stopped. Alternatively, at a second predetermined power P₂The heating of the inner container 111 is continued until the duration of the heating of the accommodating cavity reaches a second predetermined duration t₂Then, the heating is stopped, and the second heating mode is ended.

For example, in the present embodiment, the rated power P of the heater module 140_{Rated value}Is equal to 200W, the second predetermined power P₂200W. Of course, in other embodiments, the second predetermined power P₂Other values are possible, for example, when the heating module is rated at 500W, the second predetermined power may be equal to 400W.

Preferably, the fifth predetermined temperature value T₅The temperature at the end of heating the regular rice may be equal to 98 deg.c. A second predetermined duration t₂The maximum time for heating the common rice can be t is 25-t₂The time is selected within the range of less than or equal to 35 minutes.

In the above-described embodiment, the heating appliance 100 is provided with the temperature sensor, and the respective cooking steps can be controlled by detecting the temperature, and in order to reduce the manufacturing cost of the heating appliance, in the second embodiment according to the present invention, the heating appliance may not be provided with the temperature sensor, and the reheating is realized only according to the time length, which will be described in detail below.

Wherein, in order to prevent the rice in the bottom of the containing cavity from scorching due to the excessively long heating time, the first time period can be selected within the range of 8 to 30 minutes. Exemplarily, the first power P₀₁May be equal to the rated power P of the heating module 140_{Rated value}. During the period of stopping heating, the rice in the containing cavity can mutually transfer heat, so that the overall temperature of the rice is kept consistent. After the duration of the heating stop reaches the second duration, the heating module 140 may be controlled to be less than the first power P₀₁Second power P₀₂The inner container 111 is heated again. Preferably, the first time period may be selected in the range of 8 to 15 minutes, for example 10 minutes. Further, the second period of time may be selected in the range of 0.5 to 8 minutes.

During the period of time when the heating is stopped for the second time, the rice in the containing cavity can also mutually transmit heat, so that the overall temperature of the rice is kept consistent. When the heating is stopped for a duration of timeAfter the fourth time period, the heating module 140 may be controlled to be less than the second power P₀₂Third power P₀₃The inner container 111 is heated again. Preferably, the third period of time may be selected in the range of 5 to 15 minutes. More preferably, the third period of time may be selected in the range of 5 to 10 minutes, for example 8 minutes. Further, the fourth time period may be selected in the range of 0.5 to 8 minutes. Preferably, the fourth time period may be selected in the range of 1 to 3 minutes, for example 2 minutes.
