Detailed Implementation

[0048] The present invention will be further described below with reference to the accompanying drawings and embodiments. Specific Implementation Example 1:

[0049] like Figure 7 As shown: The main structure includes a pot body 10, a water level lifting chamber 1, a rice cooker 2, a regular rice steamer basket 3, an electric heating plate 4, a control circuit 5, a pot bottom temperature sensor 6-1, a pot lid temperature sensor 6-2, an operation panel 7, a pot lid 8, and a pot body 10.

[0050] The bottom temperature sensor 6-1 is located in the center of the heating plate and is in close contact with the bottom of the rice cooker 3.

[0051] The temperature sensor 6-2 is located on the lid, in the upper space of the rice steaming basket 3.

[0052] The control device 4 is electrically connected to the bottom temperature sensor 6-1, the lid temperature sensor 6-2, and the heating plate 4.

[0053] The control device adjusts the power supply and power of the heating plate according to the temperature signal sensed by the temperature sensor.

[0054] The top 1-2 of the water level lifting chamber 1 has a hole, and the lower edge of the chamber wall 1-1 of the water level lifting chamber sits directly on the bottom of the rice cooker.

[0055] The main rice cooking process in Specific Implementation Example 1 is as follows:

[0056] Put the rice into the steaming basket 3, and put the steaming basket 3 into the rice cooker 2.

[0057] Referring to Figure 6a , the water level is lower than the upper surface of the rice, and even lower than the bottom of the steaming basket.

[0058] Select the rice draining function, and determine one of the three options of soft, medium, and hard according to personal preference, and start the rice cooker.

[0059] The electric heating plate is intermittently or continuously powered to heat the rice cooker to boil water.

[0060] The water in the rice cooker is heated to a vigorous boil, and the vigorously boiling water forms a large amount of steam that collects in the water level regulator. Since only a small amount of steam can escape upward through the holes in the bottom of the steaming basket, a large amount of steam that cannot escape gathers in the space in the water level regulator to form a certain volume of steam layer.

[0061] The certain volume of steam layer occupies the space of the same volume of water in the water level regulator, causing the water level in the rice cooker and the steaming basket to be raised, and the boiling water level to rise to overflow the upper surface of the rice. At the same time, the vigorously boiling water forms a violent type of rice cooking on the rice in the steaming basket.

[0062] Referring to Figure 6b , the boiling water level is raised to overflow the upper surface of the rice, and the violent boiling impact type of rice cooking causes more starch on the surface of the rice to fall into the rice soup.

[0063] At the same time that the water in the rice cooker 2 is heated to a vigorous boil, the control device starts the rice cooking timing according to the signal of the water boiling sensed by the lid temperature sensor.

[0064] As the rice cooking process continues, the rice cooking timing of the control device is up, and the rice is cooked to about 8 minutes or so. A portion of the water is evaporated, and a portion of the water is absorbed by the cooked rice.

[0065] Referring to Figure 6c , at the same time that the rice cooking timing is up, the control device stops the power supply to the electric heating plate or greatly reduces the power supply to the electric heating plate. After a period of time, the rice soup stops boiling vigorously, and a large amount of steam does not collect in the space of the water level regulator. The steam layer in the upper space of the water level regulator disappears, causing the originally raised rice soup water level to drop significantly. In addition, a portion of the water is absorbed by the rice and a portion of the water is evaporated, so the rice soup water level after the drop will be significantly lower than the bottom of the steaming basket, achieving complete separation of the rice soup and the rice. At the same time that the power supply to the electric heating plate is stopped or the power supply to the electric heating plate is greatly reduced, the control device starts the rice draining timing.

[0066] When the timer for draining rice is up, the control device will either resume supplying a low-power power supply to the heating device to prevent the rice water from boiling violently, and at the same time, the control device will start the timer for the rice cooking stage.

[0067] When the timer for the rice steaming stage is up, the rice in the steaming basket will be fully cooked. The control device will then beep or display a message indicating that the rice is cooked. In this embodiment, the rice is cooked by completely separating the rice water from the rice. Specific Implementation Example 2:

[0068] like Figure 8 As shown: The structural differences between this embodiment and the first specific embodiment are: firstly, the lower edge of the water level lifting chamber wall 1-1 is provided with a water passage hole 1-5, and the lower edge of the chamber wall 1-1 is also directly placed on the bottom of the rice cooker; secondly, the electric heating plate 4 at the bottom of the pot is replaced with an electromagnetic induction coil 4-1.

[0069] The advantage of using electromagnetic induction to heat the rice cooker is that it does not have the same thermal inertia as electric heating plates, and it greatly speeds up the rice draining process.

[0070] The main cooking process in this embodiment is basically the same as in embodiment one. The only difference is that the time for draining the rice can be significantly shortened, and the water level of the rice water drops rapidly, making the looseness of the top layer of rice and the bottom layer of rice more consistent. Specific Implementation Example 3:

[0071] like Figure 9 As shown: The structural differences between the specific embodiment and the first specific embodiment are: firstly, a water level lifting type rice steaming basket is adopted; secondly, the lower edge of the water level lifting chamber of the integrated rice steaming basket structure is supported by support feet that contact the bottom of the rice cooker.

[0072] The main cooking process in this embodiment is the same as in Embodiment 1, and will not be repeated here. Specific Implementation Example 4:

[0073] like Figure 10 As shown: The structural differences between the specific embodiment and the first specific embodiment are as follows: First, a water level lifting type rice steaming basket is used; second, the water level lifting type rice steaming basket is suspended by the edge of the basket and the edge of the rice cooker; third, a cooling fan and air duct are set at the bottom of the rice cooker body. The fan starts to operate during the rice draining stage, and its function is to accelerate the heat dissipation and cooling of the boiling rice water in the rice cooker, thereby speeding up the process of rice draining.

[0074] The main cooking process in this embodiment is basically the same as in embodiment one. The only difference is that the operation of the fan shortens the time of the rice draining stage, which speeds up the drop in the rice water level and makes the looseness of the top layer of rice and the bottom layer of rice more consistent.
