DETAILED DESCRIPTION

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0038] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0039] In order to solve the problem that the cooking device in the prior art cannot cook low GI rice, the present invention provides a cooking method and a cooking device for rice. Among them, the following cooking device can use the following cooking method to perform cooking operations.

[0040] The cooking method of the present invention comprises: performing microwave treatment on the rice-water mixture in the cooking device for a first preset time; performing cooling treatment on the rice-water mixture in the cooking device for a second preset time; and performing heating treatment on the rice-water mixture in the cooking device.

[0041] The above cooking method can change the molecular structure or taste of the rice-water mixture by physical means, thereby obtaining low GI rice.

[0042] Optionally, the cooking method further includes draining water from the rice-water mixture after the microwave treatment reaches a first predetermined time, and then initiating a cooling process. Since the water in the cooking device is drained first, the water is separated from the rice, allowing for a quicker cooling of the rice during the subsequent cooling process. Furthermore, the draining process removes starch dissolved in the water, thereby lowering the GI value of the rice and facilitating the cooling process.

[0043] Optionally, the cooking method further includes a water replenishing process, wherein after the cooling process reaches a second preset time, water is replenished into the cooking device, and then the heating process is started. In this way, when the rice is subsequently heated, sufficient water vapor can be generated in the cooking device to improve the taste of the rice.

[0044] Optionally, the power of the microwave generator 20 for performing microwave treatment on the cooking device is greater than or equal to 300 W and less than or equal to 1500 W. In this way, it can be ensured that the rice is effectively pre-gelatinized.

[0045] Optionally, the first preset time is greater than or equal to 1 minute and less than or equal to 20 minutes.

[0046] Optionally, during the cooling process, the temperature of the rice-water mixture is lowered to 0 to 10 degrees Celsius and maintained for a second preset time. In this way, physical principles can be effectively utilized to cause some starch molecules in the rice to recrystallize and form resistant starch.

[0047] Optionally, the second preset time is greater than or equal to 1 hour and less than or equal to 72 hours. Experiments have shown that when the second preset time is greater than or equal to 1 hour and less than or equal to 72 hours, some starch molecules in the rice can be recrystallized to form resistant starch.

[0048] Further optionally, the second preset time is greater than or equal to 24 hours and less than or equal to 72 hours. Cooling and retrogradation is an essential step in producing resistant starch. The amount produced is positively correlated with the cooling time. It is recommended to retrogradation for more than 24 hours.

[0049] like Figure 1 As shown, the cooking device includes a housing 10, a container assembly arranged in the housing 10, a microwave generator 20 for performing microwave treatment on the rice-water mixture in the container assembly, a refrigeration assembly 30 for cooling the rice-water mixture in the container assembly, and a heating component 40 for heating the rice-water mixture in the container assembly. The microwave generator 20 is arranged in the housing 10; the refrigeration assembly 30 is arranged in the housing 10; and the heating component 40 is arranged in the housing 10.

[0050] The cooking device with the above structure can change the molecular structure or taste of the rice-water mixture by physical means, thereby obtaining low GI rice. Furthermore, the cooking device with the above structure has the characteristics of multiple functions.

[0051] Specifically, the cooking device employing the above structure pre-gelatinizes the rice through microwave radiation. Low-temperature treatment, during refrigeration, causes some of the starch molecules in the rice to recrystallize and form resistant starch. Finally, the rice is heated by the heating element 40 to steam or cook it. Low-temperature aging of the rice after microwave heating alters the starch structure, reducing its digestibility and ultimately achieving a low GI.

[0052] In summary, the cooking device of the present invention can increase the content of slowly digestible starch and resistant starch in rice, thereby reducing the GI value of rice, thereby achieving the purpose of cooking low-GI rice.

[0053] like Figure 1 As shown, the cooking device also includes a drain assembly 50 for draining water from the container assembly and a water replenishment assembly 60 for replenishing water into the container assembly. The drain assembly 50 is disposed within the housing 10; the water replenishment assembly 60 is also disposed within the housing 10. Specifically, when using this cooking device, the rice-to-water ratio, microwave duration, and microwave power must be adjusted in the early stages of rice cooking. The rice is then microwave-pregelatinized. The drain assembly 50 is then used to drain the water from the container assembly to separate the starch from the rice. The refrigeration assembly 30 is then activated to rapidly cool the container assembly, allowing the rice to age and regenerate. Fresh water is then injected into the container assembly via the water replenishment assembly 60, the rice-to-water ratio is readjusted, and the heating element 40 is activated to allow normal steaming of the rice. Detailed operating procedures will be described below.

[0054] Below, a detailed description will be given of the specific structures of the above-mentioned components and assemblies.

[0055] The housing 10 of the present invention comprises a shell 11 and a cover 12. The shell 11 defines a receiving cavity, within which the container assembly, cooling assembly 30, heating component 40, drainage assembly 50, and water replenishment assembly 60 are disposed. The cover 12 is mounted on the shell 11, and the microwave generator 20 is disposed on the cover 12 or within the receiving cavity. When the cover 12 is mounted on the shell 11, the receiving cavity is relatively sealed, ensuring reliable cooking of the rice-water mixture and preventing injury from hot steam.

[0056] Optionally, the microwave generator 20 is disposed in the accommodating cavity and is located below or to the side of the container assembly. The microwave generator 20 only needs to ensure that the microwave energy can directly radiate to the rice, or penetrate the container assembly to radiate to the rice.

[0057] exist Figure 1 In the embodiment shown, the microwave generator 20 is disposed on the lid 12 and located at the bottom end of the lid 12, and is located directly above the container assembly. This allows the microwave generator 20 to radiate the rice-water mixture in the container assembly more evenly, ensuring a microwave effect.

[0058] Optionally, the heating component 40 is a heating plate, a heating tube, an IH electromagnetic heating device or a heating film heating device.

[0059] exist Figure 1 In the particular embodiment shown, the heat generating component 40 is located directly below the container assembly.

[0060] like Figure 1 As shown, the container assembly includes an inner container 70, with a drain hole formed on the bottom wall of the inner container 70 and a filter 72 positioned at the drain hole. The drain assembly 50 includes a switch structure 51 to control the connection between the drain hole and the drain pipe 52 of the drain assembly 50. During use, the rice-water mixture can be directly placed in the inner container 70, and then water is added to cover the rice. At this time, the switch structure 51 maintains the disconnection between the drain hole and the drain pipe 52, preventing the water in the inner container 70 from flowing out. After the rice is microwaved, the switch structure 51 connects the drain hole to the drain pipe 52, allowing the water in the inner container 70 to drain. This allows the filter 72 to intercept the water, effectively preventing the drain hole from becoming clogged and improving the reliability of the cooking device.

[0061] exist Figure 1 In the specific embodiment shown, the center position of the bottom wall of the inner container 70 shrinks downward to form a funnel-shaped structure 71 . The bottom opening of the funnel-shaped structure 71 is a water leakage hole, and the filter screen 72 is located at the upper opening of the funnel-shaped structure 71 .

[0062] Optionally, the container assembly further includes a filter basket disposed in the inner pot 70, and the filter basket is provided with a filter hole. During use, after the rice is placed in the filter basket, the filter basket containing the rice is placed in the inner pot 70, and then water is added so that the water covers the rice. At this time, the switch structure 51 keeps the water leakage hole and the drain pipe 52 disconnected to prevent the water in the inner pot 70 from flowing out. After the rice is microwaved, the switch structure 51 connects the water leakage hole with the drain pipe 52 to drain the water in the container assembly. In this way, the rice that accidentally flows out of the filter basket is effectively prevented from being drained away through the water leakage hole, and the filter net 72 plays a secondary interception role, effectively preventing the water leakage hole from being blocked, thereby improving the reliability of the cooking device.

[0063] Optionally, the outer diameter of the filter basket is slightly larger than the inner diameter of the inner container 70 , so that the upper edge of the filter basket can be supported on the upper edge of the inner container 70 to avoid contact between the filter basket and the bottom wall of the inner container 70 .

[0064] exist Figure 1 In the illustrated embodiment, the drainage assembly 50 further includes a drainage collector 53 located at the bottom of the housing 10. A drainage pipe 52 connects the drain hole to the drainage collector 53. With this structure, the cooking device allows the water in the inner pot 70 to dissolve some of the rapidly digestible starch in the rice during the cooking process and drain it into the drainage collector 53, further reducing the GI value of the rice.

[0065] Optionally, the switch structure 51 is a valve structure.

[0066] like Figure 1 As shown, the switch structure 51 is a steel ball, which blocks the connection between the water leakage hole and the drain pipe 52 under the action of gravity.

[0067] exist Figure 1 In the illustrated embodiment, the water replenishment assembly 60 includes a water reservoir 61, a water pump 62, and a water replenishment pipe 63. The first end of the water replenishment pipe 63 is connected to the container assembly, and the other end of the water replenishment pipe 63 is connected to the water reservoir 61 via the water pump 62. Tap water can be stored in the water reservoir 61 to ensure that water can be replenished into the inner tank 70 in a timely manner after the water pump 62 is started.

[0068] The refrigeration assembly 30 of the present invention further comprises a compressor, a condenser, and an evaporator arranged in series, wherein the evaporator exchanges heat with the container assembly. The evaporator absorbs heat and evaporates to cool the rice-water mixture in the filter basket.

[0069] To improve the heat dissipation efficiency of the refrigeration assembly 30 and enhance the reliability of the cooking device, the refrigeration assembly 30 also includes a heat dissipation component for accelerating heat dissipation from the condenser. Heat dissipation holes are provided on the housing 10 at locations corresponding to the heat dissipation component. This ensures stable circulation throughout the refrigeration assembly 30 and reliable operation of the cooking device.

[0070] The cooking device of the present invention further includes a controller 80, which is connected to the microwave generator 20, the heating component 40, the cooling assembly 30, the drainage assembly 50, and the water replenishment assembly 60. The controller 80 can control and adjust each of the above components and assemblies to ensure that they work together.

[0071] In addition, the cooking device further includes a display component connected to the controller 80 to display operating status information of the microwave generator 20, the heating component 40, the cooling assembly 30, the drainage assembly 50, and the water replenishment assembly 60. The display component is provided on the housing 10 for easy viewing by the user.

[0072] The following summarizes the working process of the cooking device. The working process of the cooking device can be divided into two types according to whether there is a filter basket or not.

[0073] The first type uses a filter basket. After thoroughly washing the rice until it is free of white turbidity, place it in the filter basket. A steel ball is placed in the inner pot 70 to seal any leaks. The filter basket is then placed in the inner pot 70 and water is added until the rice is completely covered. The cooking device is powered on, and the microwave generator 20 is set to a power of 300W to 1500W. The controller 80 activates the microwave generator 20 to irradiate the rice. After 1 to 20 minutes of irradiation, the microwaves cease, and the drainage assembly 50 activates. The steel ball gently bounces upward, draining some of the water in the inner pot 70 into the drainage collector 53. After drainage ceases, the controller 80 activates the refrigeration assembly 30 to cool the rice, rapidly lowering the temperature in the filter basket to between 0 and 10°C. After 1 to 72 hours, the refrigeration assembly 30 is deactivated to complete starch regeneration. The water replenishment assembly 60 is activated to fill the inner pot 70 with water. The controller 80 then activates the heating element 40 to continue heating the rice until it is cooked.

[0074] The second method is to use a filter basket without a filter basket. A steel ball is placed in the inner pot 70 to seal the leaking hole. The rice is then rinsed thoroughly until there is no white turbidity and placed in the inner pot 70. Water is then added to the inner pot 70 until the rice is submerged, using a rice-to-water ratio of 1:0.8 to 1:3. The cooking device is powered on, with the microwave generator 20 set to a power of 300W to 1500W. The controller 80 activates the microwave generator 20, irradiating the rice with microwaves. After 1 to 20 minutes of irradiation, the microwaves cease, and the drainage assembly 50 activates. The steel ball gently bounces upward, draining some of the water in the inner pot 70 into the drainage collector 53. After drainage ceases, the controller 80 activates the refrigeration assembly 30 to cool the rice, rapidly dropping the temperature in the filter basket to 0 to 10°C. After 1 to 72 hours, the refrigeration assembly 30 is deactivated to complete starch retrogradation. The water replenishment assembly 60 is activated to inject water into the inner pot 70. The controller 80 then activates the heating element 40 again to continue heating the rice until the rice is cooked. At this point, the rice is typically cooked, meaning that no excess water remains in the inner pot 70.

[0075] It should be noted that the bouncing of the steel ball can be achieved through a small lever device. When drainage is required, the controller connects to the switch structure of the drainage component, and the lever can lift the steel ball; when drainage is not required, or when drainage is completed, the switch structure is closed, the lever returns to its original position, and the steel ball is stuck in the drain pipe due to gravity to prevent liquid leakage.
