[0002] An electric rice cooker, also known as an electric pot or rice cooker, is a cooking utensil that converts electrical energy into internal energy and is an essential household appliance in daily life. The current electric rice cookers have the following deficiencies:

[0003] 1. Slow heating: When cooking rice with the existing electric rice cooker, cold water is added. It is necessary to first heat the cold water to boiling and then gradually cook the rice, resulting in low heating efficiency and a long waiting time for the user during cooking.

[0004] 2. High sugar content in the cooked rice, which is not conducive to health: The existing hypoglycemic rice cookers use a filter to separate rice and water to achieve hypoglycemic effect. Due to structural limitations, the volume of the rice pot is limited, and the ratio of rice to water basically remains at 1:3 or 1:2.5. The amount of water is less, and the dilution of soluble starch in rice is insufficient, resulting in poor hypoglycemic effect.

[0005] 3. Unable to perform remote control and manual rice washing is required: The existing rice cookers cannot achieve remote control and automatic rice washing function. The user needs to manually wash the rice clean before putting it into the rice cooker for steaming, which is time-consuming.

[0006] 4. Artificial control of the water addition amount is required: Currently, when cooking rice, users need to detect the amount of water according to the amount of rice and accurately add an appropriate amount of water to steam qualified rice, which is quite demanding on experience. For those who are not good at cooking rice, it is easy to fail in steaming rice. Summary of the Invention

[0007] The purpose of the present invention is to provide a novel rice steaming appliance and its control system. A water storage tank is provided on the side of the pot body, and a waste water box is provided at the lower part of the pot body.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] All orientations mentioned in this specification are based on the orientations when a new type of rice steaming appliance of the present invention and its control system are working properly, without limiting their orientations during storage and transportation. They only represent relative positional relationships, not absolute positional relationships.

[0031] As Figures 1 to 3As shown together, a new type of rice steaming appliance includes a housing 1. Inside the housing 1, there is a pot body 2. Above the pot body 2, there is a pot lid 11. The pot body 2 is equipped with a heating device 3 for heating the food inside the pot body 2. On the side of the pot body 2, there is a water storage tank 4. The pot body 2 and the water storage tank 4 are connected through a water inlet pipe 5. A water pump 9 is connected to the water inlet pipe 5. Under the control of the control system, when needed, the water pump 9 pumps the water in the water storage tank 4 into the pot body 2 to wash or steam the rice. At the lower part of the pot body 2, there is a waste water bin 6. Inside the waste water bin 6, there is a waste water box 7. The pot body 2 and the waste water box 7 are connected through a drain pipe 8. Each component of the device is connected to the control system and works orderly under the control of the control system.

[0032] The outer wall of the water inlet pipe 5 is wrapped with an instant heating pipe 10. When water flows through the water inlet pipe 5, the instant heating pipe 10 preliminarily heats the cold water. In this embodiment, the heating pipe 10 is spirally wound around the outer pipe wall of the water inlet pipe 5, with a larger heat receiving area and a faster heating speed. By using the instant heating technology, the time for heating water to boiling in a traditional rice cooker is reduced, the waiting time of users is decreased, and the heating efficiency of the rice cooker product is improved. Preferably, the outside of the heating pipe 10 is wrapped with heat insulation material to reduce heat loss.

[0033] A filter screen is provided inside the drain pipe 8 to prevent rice grains from entering the drain pipe 8 during drainage. The drain pipe 8 and the filter screen are detachably installed at the lower part of the pot body 2, which is convenient for disassembly and cleaning. A drain valve is connected to the drain pipe 8. The drain valve opens and closes under the control of the control system, so as to drain the excess waste water in the pot body 2 into the waste water box 7. Specifically, during the rice washing stage, the drain valve opens to drain the dirty water from rice washing into the waste water box 7, and then closes to enter the steaming stage. During the steaming stage, the drain valve opens to inject an appropriate amount of clean water into the pot body 2 to form a water-to-rice ratio of 5:1. The heating device 3 starts to heat. After heating the water-rice mixture to a certain temperature, the drain valve opens to drain the excess water, and continues to heat until the rice is completely cooked. A higher water-to-rice ratio can fully dilute the soluble starch in the rice, and the dissolution ratio is greatly increased. Finally, the excess water dissolved with starch sugar is drained through the drain valve, so that the residual starch content in the rice is lower, the steamed rice is healthier, the blood sugar rising speed is slower, and it is more beneficial to health.

[0034] Furthermore, a water level sensor is also installed inside the waste water box 7. When the water level of the waste water exceeds the highest water level line, the machine will give an alarm to remind the user to clean the waste water.

[0035] Furthermore, the waste water box 7 is slidably installed at the lower part of the pot body 2, and the water storage tank 4 is slidably installed at the rear side of the pot body 2. The sliding installation design makes it convenient to disassemble and clean the waste water box 7 and the water storage tank 4.

[0036] Further, a water level sensor and a temperature sensor are provided inside the pot body 2. The water level sensor and the temperature sensor are connected to the control system, which facilitates the detection of the water level and temperature inside the pot body 2 and enables corresponding subsequent actions.

[0037] As Figure 4 shown, a control system of a novel rice steaming appliance as described above includes a main control board. The input end of the main control board is connected to the temperature sensor, the water level sensor, and the remote controller. The remote controller is connected to the main control board through wireless technology. Through the remote controller, various parameters can be set for the rice steaming appliance, such as the time to start cooking rice. The output end of the main control board is connected to the water pump 9, the heating tube 10, the heating device 3, and the drain valve.

[0038] The specific control process is as Figure 5 shown. The user puts rice in the pot in advance and sets the cooking start time on the remote controller. When the time arrives, the water pump 9 pumps water from the water storage tank 4 into the pot body 2. The water flow direction is as shown by the hollow arrow in Figure 3 . The rice grains in the pot body 2 roll under the impact of the water flow and come into full contact with the water, automatically completing the washing process. Then the water pump 9 is turned off, the drain valve is opened, and the waste water after washing is completely discharged into the waste water box 7, and then the drain valve is closed.

[0039] Entering the cooking program, the water pump 9 works again to pump water from the water storage tank 4 into the pot body 2. At the same time, the heating tube 10 on the outer wall of the water inlet pipe 5 heats up to preheat the water, saving cooking time. When the water-to-rice ratio in the pot body 2 reaches 5:1, the water injection stops, and the heating device 3 is turned on to continue heating the pot body 2. When the water temperature rises above 53 °C, the starch will undergo a gelatinization reaction, and the starch in the rice will diffuse into the water, thereby reducing the starch content in the rice and making the blood sugar rising speed of the rice slower. At this time, the drain valve is opened, and the drain pipe 8 discharges the excess starch-dissolved rice soup into the waste water box 7. And the water level sensor inside the pot body 2 continuously feeds back the water level in the pot body 2 to the main control board. When the water volume reaches the set value, the drain valve is closed, and the drain pipe 8 stops draining. After the drainage is completed, the heating device 3 continues to heat until the rice is cooked.

[0040] This process can, on the one hand, take away as much starch in the rice as possible, making the steamed rice healthier. On the other hand, through the drain valve, the excess water is discharged, eliminating the need for the user to measure the water addition amount during cooking. The whole process is automated, simple and convenient. Even people who can't cook can easily use it, saving time and effort.

[0041] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
