As described above, the pump system 4 can suck the rice water from the first inner pot 2 into the second inner pot 3 through the first water suction pipe 411 and suck the rice water from the first inner pot 2 into the second water storage chamber 52 to recover the rice water, and the clean water stored in the first water storage chamber 51 can be injected into the first inner pot 2 through the second water suction pipe 412, both by controlling the plurality of switching valve sets 40 provided in the pump system 4.
In order to make the rice cooker 100 better realize the blood sugar reduction cooking, as shown in fig. 1, the rice cooker 100 is further provided with a temperature sensor 6 for detecting the temperature of the first inner pot 2, the temperature sensor 6 is connected with the controller, and the controller can respond to the signal of the temperature sensor 6 to turn on or off the first heater 21. In this embodiment, the temperature sensor 6 includes a first sensor 61 disposed at the bottom of the first inner pan 2 and a second sensor 62 disposed on the first pan cover 25 and extending into the first inner pan 2, and the first sensor 61 and the second sensor 62 can sense the temperature of the first inner pan 2 and transmit a temperature signal to the controller; the controller can sense signals of the temperature sensor 6 to know whether the temperature of the first inner pot 2 exceeds a set temperature range, and the controller controls the first heater 21 to intermittently heat, so that the first inner pot 2 is maintained for 8-25 minutes in a low-temperature environment of 35-65 degrees, and the aim of soaking rice at low temperature is fulfilled. In addition, in the process that the water in the first inner pot 2 is boiled and the rice is completely cooked, the controller can know whether the temperature of the first inner pot 2 reaches a preset temperature range or not by sensing the signal of the temperature sensor 6, and the first heater 21 is controlled to heat the first inner pot 2 so as to boil the rice water in the pot. The temperature sensor 6 also prevents the first inner pot 2 from being dried due to water shortage, thereby improving the safety of the electric cooker.
The electric cooker 100 is used for cooking, and in the low-sugar cooking process, as shown in fig. 6, the invention also discloses a method for simultaneously cooking hypoglycemic rice and common rice by using the electric cooker 100, the electric cooker 100 with double inner containers and rice and water for cooking are configured, and the following cooking steps are adopted:
s1: the first heater 21 is started to preheat the first inner pot 2 by manually injecting clean water into the first inner pot 2 for the first time or pumping clean water from the first water storage chamber 51 through the pump system 4 and injecting clean water into the first inner pot 2 for the first time, and simultaneously adding a proper amount of rice into the first inner pot 2 and the second inner pot 3 respectively;
s2: after the preheating is completed by stopping the heating of the first heater 21, first pumping away the rice water in the first inner pot 2 by the pumping system 4 and adding at least a part of the pumped rice water to the second inner pot 3;
s3: pumping clean water from the first water storage chamber 51 by the pump system 4 and injecting clean water into the first inner pot 2 for a second time;
s4: the first heater 21 is again activated to continue heating the first inner pot 2 until the rice is cooked, and the second heater 31 is also activated to heat the second inner pot 3 until the rice is cooked.
Further, in step S1, the first inner pot 2 is preheated at 35 ° to 65 ° for 8 to 25 minutes so as to soak the rice in the first inner pot 2 at a low temperature.
Further, in step S4, before the rice in the first inner pot 2 is cooked, the pump system 4 pumps the rice water in the first inner pot 2 for a second time and transfers the rice water to the second water storage chamber 51, and then the pump system pumps the clean water from the first water storage chamber 51 and injects the clean water into the first inner pot 2 for a third time, and then the pump system pumps a part of the rice water in the first inner pot 2 for a third time and transfers the rice water to the second water storage chamber 51, and only the amount of water for allowing the rice to be cooked is reserved.
Further, after the first inner pot 2 finishes cooking, the pump system 4 pumps clean water from the first water storage chamber 51 and injects the clean water into the first inner pot 51; the pump system 4 pumps clean water from the first inner pot 2 and then returns the clean water to the first inner pot 2, so that the first inner pot 2 and the pump system 4 are repeatedly cleaned for multiple times.
Further, after the first inner pot 2 and the pump system 4 are repeatedly cleaned and the second inner pot 3 finishes cooking, the pump system 4 further conveys the pot washing water in the first inner pot 2 to the second inner pot 3.
Wherein, when the pump system 4 pumps away the soaking water or rice water in the first inner pot 2 for the first time, the controller controls the first heater 21 to suspend heating. This is because the rice-water in the first inner pot 2 generates many bubbles and makes the surface level of the rice-water unstable after the rice-water is boiled, which makes the pump system 4 may not continuously pump the rice-water and thus the amount of pumped rice-water is small when the rice-water in the first inner pot 2 is pumped. And the first heater 21 is controlled by the controller to suspend heating when the pump system 4 pumps the rice water, so that the rice water in the first inner pot 2 becomes stable to ensure the amount of the rice water pumped by the pump system 4, thereby effectively reducing the sugar content of the rice. Further, in order to ensure the cooking effect of the electric rice cooker, after the pumping system 4 finishes pumping the boiled rice water in the first inner pot 2, clean water is injected into the first inner pot 2 again, at this time, the controller starts the first heater 21 to continue heating, and after the pumping system 4 finishes water injection, part of the rice water in the first inner pot 2 is pumped away again and conveyed into the second water storage chamber 3 to be recycled, and only the water quantity which can enable rice to continue to be cooked is reserved. Set up the order of heating after the water injection like this, guarantee leave sufficient water in the pot 2 in the first, be favorable to controlling the temperature of pot 2 can not be too high in the first, reduces the rice in the pot 2 sticks with paste the end phenomenon and takes place, guarantees in the first electric rice cooker's culinary art effect. Further, the controller controls the first heater 21 to intermittently heat during the complete cooking of the rice in the first inner pot 2. The heating mode can keep the temperature in the pot in a stable and proper state so as to well finish the cooking of the rice in the pot; meanwhile, intermittent heating can control the rice water in the first inner pot 2 not to generate large boiling, so that the rice water is prevented from being attached to the rice again due to boiling, and the blood sugar reducing effect of the rice is effectively ensured.
Since the pump system 4 pumps the rice water from the first inner pot 2, in order to reduce the influence of the rice water on each component of the pump system 4, the interior of the pump system 4 needs to be cleaned periodically, after the first inner pot 2 is cooked, clean water is pumped from the second water storage chamber 51 and filled into the first inner pot 2, and the pump system 4 pumps clean water from the first inner pot 2 and returns to the first inner pot 2, so that the interior of the first inner pot 2 and the interior of the pump system 4 are cleaned repeatedly for a plurality of times. After the interior itself has been cleaned, the pump system 4 pumps the boiler water back into the second inner boiler 3 or the second water storage chamber 52. In this way, the first pumping line 411, the three fluid delivery lines, the main pump 43, the switching valve group 40, etc. of the pump system 4 can be cleaned.
