[0002] Common rice cookers on the market today require manual work such as washing rice and adding water, resulting in a low level of intelligence and automation. Furthermore, since the rice-to-water ratio needs to be within an appropriate range for the rice to taste good, cooking rice is a skill that requires experience. This is especially true for children and beginners, who lack this experience and may end up with poorly cooked rice if they add the wrong amount of water.

[0003] Although some rice cookers on the market also have a timer function, when using the timer function, it is also necessary to manually rinse the rice with water first, then keep the rice-water mixture in the rice cooker, and then start the timer function. This does not achieve automatic rice washing. Therefore, the existing technology still has defects. Summary of the Invention

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples.

For example, the first control information and the second control information are merely used to distinguish different control information and do not limit their order.

[0049] Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit them to be different.

[0050] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0051] To address the problems of the prior art, this embodiment provides a method for automatically washing rice in an electric rice cooker. This method can automate the entire rice-washing process. In specific applications, this embodiment first receives a voice command and, based on the voice command, controls the electric rice cooker to start operation. Next, it controls the entry of rice and water into the inner pot of the electric rice cooker, controls the extension of a pre-set rice-washing unit, and performs the rice-washing operation. Finally, after the rice-washing operation is completed, the rice-washing unit is controlled to retract back to its initial position, and the rice-washing water in the inner pot is removed. As can be seen, in this embodiment, the user only needs to issue a voice command, which is received by the voice interaction module. The controller then controls the rice-input, water-input, rice-washing, and water-out processes, and then enters the rice-cooking phase. This eliminates the need for manual user operation throughout the entire process, bringing greater convenience to people's lives. Furthermore, since each action of the electric rice cooker in this embodiment is automatically performed according to a program, there are no errors caused by human operation and is not affected by human experience. After the rice-washing operation is completed, the rice-cooking phase immediately begins, which helps ensure the rice's taste.

[0052] The automatic rice-washing control method of the rice cooker of this embodiment can be applied in a terminal, and can also be applied in an artificial intelligence rice cooker. When applied in an intelligent rice cooker, the automatic rice-washing control method of the rice cooker of this embodiment can be implemented based on the controller in the intelligent rice cooker. Specifically, Figure 1 As shown in , the automatic rice washing control method of the electric rice cooker of this embodiment comprises the following steps:

[0053] Step S100: receiving a voice command, and controlling the rice cooker to start working based on the voice command.

[0054] Combine Figure 2 As shown, the smart rice cooker of this embodiment includes: a rice cooker body 10, a voice interaction module 20, a water inlet pipe 30, a rice washing part 40, and a water extraction pipe 50. The rice cooker body 10 includes an upper cover 110 and a lower shell 120. A cavity is formed in the lower shell 120, and an inner liner 130 is provided in the cavity. The inner liner 130 is used for cooking rice. In this embodiment, the upper cover 110 and the lower shell 120 can be a separate design or an integrated design. When the upper cover 110 and the lower shell 120 are a separate design, the upper cover 110 and the lower shell 120 are hinged. In this case, the upper cover 110 can be opened or fixedly fastened to the lower shell 120. The fastening method can be a snap-on method. For example, a movable protrusion is provided on the edge of the upper cover 110, and a groove corresponding to the protrusion is provided on the edge of the lower shell 120. When the protrusion is snapped into the groove, the upper cover 110 is fastened to the lower shell 120. When the upper cover 110 and the lower housing 120 are designed in one piece, the upper cover 110 is formed integrally with the lower housing 120. Whether the upper cover 110 and the lower housing 120 are designed in a split or integrated manner, the function and effect of the rice cooker of this embodiment are not affected.

[0055] Furthermore, in order to realize automatic rice washing, the electric rice cooker body 10 of the present embodiment is provided with a voice interaction module 20 and a controller. The voice interaction module 20 can be arranged at any position on the outer surface of the lower housing 120. As long as it does not affect the reception of the voice command, the controller can be built into the electric rice cooker body 10, and the voice interaction module 20 is connected to the controller. After the user issues a voice command to start cooking rice, the voice interaction module 20 receiving module receives the voice command, and then transmits the received voice command to the controller, and the electric rice cooker can start working. At this time, the controller can send a control command to control the corresponding components to start washing rice, cooking rice, etc., thereby realizing automatic processing. In the present embodiment, the voice interaction module 20 can be a microphone device, and the controller can be a chip processor, such as the chip of the NRK330X series and the NRK3502 series. The NRK330X series is a high-performance, low-cost voice recognition chip. It has a high-performance 32-bit RISC core, a main frequency of 240MHz, and a built-in 1MB SPI FLASH (NRK3303 is 512KB). It uses a TDNN algorithm for precise recognition and far-field noise reduction, supporting up to 100 offline instructions. It supports multiple audio decoding formats and is equipped with a variety of peripheral interfaces, making it suitable for smart home appliances, smart bathrooms, and other fields. The NRK3502 series is a Bluetooth dual-mode intelligent voice IoT chip. It integrates a 32-bit CPU processor with an operating frequency of 240MHz, a built-in NPU, and a floating-point unit. It supports 50 local instructions for offline 3-5 meter far-field recognition and supports a lightweight RTOS system. It integrates multiple peripheral interfaces and supports Bluetooth V5.1+BR+EDR+BLE, making it suitable for IoT fields such as smart home appliances, smart homes, wireless audio and video, and more.

[0056] In addition, when the voice interaction module 20 of this embodiment conducts voice interaction with the user, it can also intelligently configure voice emotional information based on the interaction scenario or user identity. For example, when the hostess of the house issues a voice command, the voice interaction module 20 responds using the tone and intonation of a domineering president; for example, when a child issues a voice command, the voice interaction module 20 can also respond using the tone and intonation of a child, thereby providing emotional value to the user, enhancing the fun of interaction, and bringing more personalized services to the user.

[0057] Step S200: Control the rice and water to enter the inner pot of the rice cooker, control the preset rice washing part to extend, and wash the rice.

[0058] Since the rice cooker of this embodiment is fully automatic, once the rice cooker enters operation, it automatically controls the entry of rice and water into the inner pot of the rice cooker, thereby controlling the extension of a preset rice-washing portion to perform the rice-washing operation. Specifically, the controller of this embodiment can issue a control command for opening the rice inlet valve, and when the amount of rice entering reaches a preset amount, it can issue a control command for closing the rice inlet valve.

[0059] Combine Figure 2 As shown, the upper cover 110 of the present embodiment is respectively provided with a water inlet pipe 30, a rice washing portion 40, a water extraction pipe 50 and a rice feeding pipe 60. One end of the rice feeding pipe 60 is connected to the upper cover 110, facing the inner container 130, and the other end is connected to a preset rice box 70, in which a desiccant is placed. In actual application, the lid of the rice box 70 of the present embodiment can be opened, and the lid is provided with a rubber ring for sealing, which is conducive to better storage of rice. The volume of the rice box 70 of the present embodiment can be selected, such as the specification that can accommodate the amount of rice for a family for half a month, or the specification that can accommodate the amount of rice for a family for a week. In addition, the rice feeding pipe 60 of the present embodiment is provided with a rice feeding valve 61, which is a solenoid valve. The rice feeding valve 61 is connected to a controller, so that the controller can issue a control instruction to control the rice feeding valve 61, such as controlling the opening of the rice feeding valve 61 to allow rice to enter the inner container 130, or controlling the closing of the rice feeding valve 61 to stop rice from entering the inner container 130. Therefore, in an actual application scenario, after the user issues a voice command, the controller can issue a control command to open the rice inlet valve 61, the rice inlet valve 61 opens, and the rice enters the inner tank 130. When the amount of rice entering the inner tank 130 reaches the preset rice inlet amount, the controller can issue a control command to close the rice inlet valve 61, and the rice inlet valve 61 closes.

[0060] Further, when judging whether the amount of rice to be fed reaches the preset amount of rice to be fed, the present embodiment can, in the process of feeding rice, record the time of feeding rice based on a timer.Then based on the time of feeding rice and the speed of feeding rice, judge whether the amount of rice to be fed reaches the preset amount of rice to be fed.Specifically, a timer can also be set in the electric rice cooker body 10 of the present embodiment. The timer can be connected with the controller with the rice feeding valve 61 simultaneously. The timer can automatically calculate the amount of rice that the rice feeding pipe 60 enters the inner bag 130. After the amount of rice to be fed reaches the preset amount of rice to be fed, the rice feeding valve 61 can be automatically closed. For example, the preset amount of rice to be fed is 300g, that is to say that the user only needs 300g of rice to cook rice. After the rice feeding valve 61 is opened, the timer starts working. Based on the flow velocity (i.e., the speed of feeding rice) and the time of feeding rice from the mouth of the rice feeding pipe 60, the amount of rice to be fed into the inner bag 130 can be calculated. After calculating the amount of rice to be fed and reaching 300g, the rice feeding valve 61 can be controlled to close, realizing the accurate control of the amount of rice to be fed.

[0061] In another implementation, when determining whether the amount of rice fed in has reached the preset amount of rice fed in, this embodiment can also detect the weight change of the inner liner in real time during the process of feeding the rice based on a gravity sensor preset below the inner liner. Then, based on the weight change, it is determined whether the amount of rice fed in has reached the preset amount of rice fed in. Specifically, in this embodiment, a gravity sensor can also be provided below the inner liner 130, and the gravity sensor is connected to the controller. The gravity sensor detects the weight change of the inner liner 130 in real time. When the rice feeding valve 61 is opened, rice enters the inner liner 130. At this time, the weight of the inner liner 130 changes. For example, when the gravity sensor detects that the weight of the inner liner 130 has increased by 300g, that is, the preset amount of rice fed in has been reached, the controller can then issue a control instruction to close the rice feeding valve 61, thereby achieving precise control of the amount of rice fed in.

[0062] In addition, the rice cooker of this embodiment can pre-set the amount of rice to be fed each time based on the number of family members. For example, if Family A has three people, the amount of rice fed each time is set based on the food intake of each person at 1.5 liang (approximately 200g). Therefore, the amount of rice fed each time is 4.5 liang (approximately 200g). In addition, this embodiment can also analyze the age data of family members based on the AI ​​algorithm to intelligently adjust the amount of rice fed. For example, if the age data analysis indicates that there are children in the family, such as if Family A has two adults and one child and the child's food intake is relatively small, the child's food intake can be intelligently adjusted to 1 liang (approximately 200g). In this case, the amount of rice fed each time is 4 liang (approximately 200g). In another implementation, the rice cooker of this embodiment can also detect whether there is any rice remaining in the inner pot 130 after each meal. It can also detect the amount of rice remaining after each meal over a period of time (e.g., three consecutive days). Then, based on the detected remaining amount, the amount of rice fed for the next meal can be intelligently adjusted based on the AI ​​algorithm, thereby meeting the needs of more humane and intelligent use and improving the user's quality of life.

[0063] Furthermore, one end of the water inlet pipe 30 of this embodiment is connected to the upper cover 110 and faces the inner tank 130, and the other end of the water inlet pipe 30 is connected to the water purifier 80 or the water dispenser. Similarly, in this embodiment, a water inlet valve 31 is provided on the water inlet pipe 30, and the water inlet valve 31 is connected to the controller, so that the controller can issue a control instruction to control the water inlet valve 31, for example, to control the water inlet valve 31 to open so that water flows into the inner tank 130, or to control the water inlet valve 31 to close so that water stops flowing into the inner tank 130. Therefore, in an actual application scenario, when the rice enters the inner tank 130, the controller can issue a control instruction to open the water inlet valve 31, and when the water reaches a certain amount, the controller can issue a control instruction to close the water inlet valve 31.

[0064] Similarly, when determining whether the water intake has reached the preset intake volume, this embodiment can record the intake time using a timer during the intake process. Then, based on the intake time and the intake speed, determine whether the water intake has reached the preset intake volume. For example, when the water inlet valve 31 is opened, the timer starts running, and the water intake volume entering the inner liner 130 is calculated based on the flow rate of water from the outlet of the water inlet pipe 30 (i.e., the intake speed) and the intake time. When the water intake volume reaches the preset intake volume, the water inlet valve 31 can automatically close. Furthermore, this embodiment can also detect the weight change of the inner liner in real time during the intake process using a gravity sensor located below the inner liner. Then, based on the weight change, determine whether the water intake has reached the preset intake volume. For example, when the water inlet valve 31 is opened and water enters the inner liner 130, the weight of the inner liner 130 changes. When the gravity sensor detects that the weight of the inner liner 130 has increased by a preset value, indicating that the preset intake volume has been reached, the controller can issue a control instruction to close the water inlet valve 31, thereby achieving precise control of the water intake volume.

[0065] In another implementation, a liquid level sensor can be installed on the inner container 130 of this embodiment, connected to the controller. Therefore, when water enters the inner container 130, the liquid level sensor can detect changes in the liquid level. When the liquid level reaches the required level, the controller can issue a control instruction to close the water inlet valve 31, thereby achieving precise control of the water intake. In this embodiment, both the rice inlet valve 61 and the water inlet valve 31 can be electrically operated, which helps improve control sensitivity.

[0066] Furthermore, when water enters the inner pot 130, the rice washing unit 40 begins to operate. In this embodiment, the rice washing unit 40 is located on the inner side of the upper cover 110. During rice washing, the rice washing unit 40 automatically extends and enters the inner pot 130 to wash the rice. Specifically, one end of the rice washing unit 40 is hinged to the inner side of the upper cover 110, allowing the rice washing unit 40 to be controlled to rotate from its initial position, located on the inner side of the upper cover 110, to a position perpendicular to and facing the inner pot 130.

[0067] In order to facilitate the rice washing operation, the rice washing part 40 of this embodiment is made of a flexible material and can be deformed, so that the rice washing part 40 can be automatically stored inside the upper cover 110 after the rice washing is completed. Specifically, the flexible material can be a food-grade material that is safe and non-toxic, ensuring the user's dietary health. In actual application, the rice washing part 40 can be set to a telescopic structure, and the rice washing part 40 can be extended by a stepper motor and retracted by a stepper motor. In addition, combined with Figure 2As shown, one end of the rice washing part 40 of this embodiment can be directly hinged to the inner side of the upper cover 110, and an electric valve can be provided at the hinge, which is connected to the controller. When washing rice is needed, the rice washing part 40 can be controlled to rotate along the hinge to control the rice washing part 40 from the initial position (such as Figure 4 As shown) rotated to face the inner container 130 and perpendicular to the inner container 130, as shown Figure 3 , and the end of the rice-washing part 40 enters below the liquid level of the inner container 130, and then the controller sends a command to the electric valve to control the rice-washing part 40 to swing along the vertical plane, and can swing 10 degrees to the left and right, or control the end of the rice-washing part 40 to rotate in the inner container 130 to achieve rice washing. In another implementation, a plurality of blades 41 are provided on the end of the rice-washing part 40 of this embodiment for washing rice, forming a claw-shaped end. These blades 41 can be used to simulate the appearance of hands washing rice, thereby improving the rice-washing effect and efficiency. Preferably, as Figure 3 As shown, the present embodiment has four blades 41, which are symmetrically arranged on the left and right sides of the end of the rice washing part 40. Whether the rice washing part 40 swings or rotates, the rice washing effect can be achieved. In addition, in order to improve the efficiency of rice washing, the present embodiment can be provided with two rice washing parts 40, such as Figure 5 As shown, the rice washing part 40 can be symmetrically arranged on the left and right sides of the inner side of the upper cover 110. In this way, based on the simultaneous operation of the two rice washing parts 40, the rice can be washed better and the washing speed can be increased. In other implementations, the shape of the blades 41 can also be set in this embodiment, and can be set to a plane, a strip or an arc surface. In addition, the thickness of the blades 41 is set to be uniform, especially the edges should be blunt and not sharp to avoid damage to the rice grains during rotation. The rice washing part 40 and its blades 41 in this embodiment are made of food-grade flexible material, which reduces friction damage when contacting the rice grains, and the broken rice rate can be controlled to below 5%.

[0068] Step S300: After the rice washing is completed, the rice washing part is controlled to be stored back to the initial position, and the rice washing water in the inner pot is extracted.

[0069] Furthermore, when the rice washing is finished, the rice washing part 40 is controlled to rotate back to the inner side of the upper cover 110 along the hinge to be stored. Figure 4As shown, it returns to its initial position. After washing the rice, the rice-washing water in the inner container 130 needs to be pumped out. A water extraction pipe 50 is also provided above the upper cover 110 of this embodiment. One end of the water extraction pipe 50 connects to the upper cover 110 and extends into the inner container 130, while the other end of the water extraction pipe 50 connects to the drainpipe. A water pump 51 is provided on the water extraction pipe 50, and the water extraction pipe 51 is connected to the controller. Therefore, the controller can issue control commands to turn the water extraction pump 51 on and off. For example, when washing the rice is finished, the controller issues a control command to turn on the water extraction pump 51, causing the pump 51 to start operating and pump the rice-washing water into the drainpipe. When all the water has been pumped out, the controller issues a control command to turn off the water extraction pump 51, completing the pumping process. Furthermore, a filter structure is provided on the end of the water extraction pipe 50 that extends into the inner container 130 of this embodiment. The filter structure is detachably connected to the water extraction pipe 50. This filter structure ensures that only water is extracted, not rice, during the pumping process. Since the filter structure is detachably connected to the water extraction pipe 50, the filter structure is replaceable. When the filter structure is damaged or clogged, a new filter structure can be replaced. In addition, in other implementations, the present embodiment can also be provided with a double-layer filter structure, for example, the pore size of the upper filter structure is 1.5 mm, and the pore size of the lower filter structure is 0.8 mm, so that the rice washing water can be discharged while the rice grains are retained.

[0070] In this embodiment, the number of times the rice is washed can be set. For example, two washes are set. Therefore, in actual use, when the user issues a voice command to start cooking rice, the voice interaction module 20 receives the voice message, and the controller issues a command to open the rice inlet valve 61. After the rice enters the inner pot 130, the controller issues a command to open the water inlet valve 31, allowing water to enter the water inlet pipe 30. When the water volume reaches the preset water volume, the controller issues a command to close the water inlet valve 31. The controller also issues a command to extend the rice washing unit 40, and the rice washing process begins. After the rice washing is completed, the controller issues a command to retract the rice washing unit 40. The controller then issues a command to start the water pump 51, and the rice washing water is pumped out. After the rice washing water is pumped out, the controller issues a command to stop the water pump 51. Then, the second rice washing is performed, and the controller issues a command to open the water inlet valve 31 again. The above-mentioned water intake, rice washing, and water pumping operations are repeated, completing the rice washing process twice. When the rice washing is completed, the controller controls the rice cooker to enter the rice cooking program, and the heating plate below the inner pot 130 begins to operate. When the rice is cooked, the controller controls the rice cooker to enter the keep warm program. Preferably, in actual application, there can be a voice prompt when the rice cooker enters any stage, so that the user knows each stage and progress, providing the user with a more intelligent experience and convenience.

[0071] In other implementations, the electric cooker body 10 of the present embodiment may also be provided with a communication module, and this communication module may be connected to a user's mobile terminal, such as a mobile phone or a wearable device. Therefore, the status data of the electric cooker may be obtained through the mobile phone or the wearable device, and each stage and progress may be understood. Furthermore, an app may be provided on the mobile phone or the wearable device, with control icons for the various functions of the electric cooker provided on the app, and remote control instructions may be issued based on these control icons. Once the electric cooker receives the remote control instructions, it may control the various functions of the electric cooker based on the remote control instructions, thereby achieving remote interaction. In actual applications, the present embodiment may issue remote control instructions to the electric cooker via text input or voice input on the user's mobile phone, allowing not only the various functions of the electric cooker to be controlled but also specific information about the rice being cooked, such as requiring the rice to be softer at noon or for a longer heat preservation time, thereby providing more convenience to the user and improving the user experience.
