Detailed Implementation

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0031] like Figures 1 to 4As shown, a rice cooker's steaming device includes a bottom shell, an inner pot, a steamer basket, a lifting device, an electrical connector, and a heater. The bottom shell is connected to the bottom of the inner pot. The bottom shell serves as the basic support structure of the rice cooker and is tightly connected to the bottom of the inner pot to ensure the stability of the entire device. The inner pot, as the main container for cooking food, has optimized material and shape to ensure even heat distribution and improve cooking results. Typically, the inner wall of the inner pot is marked with water volume markings, as shown in the attached figure. The lifting device includes a lifting drive and a lifting moving assembly. The lifting drive is located inside the bottom shell and is kinetically connected to the lifting moving assembly. The steamer basket is connected to the lifting moving assembly. This design allows the steamer basket to automatically adjust its position as the lifting moving assembly moves, without manual intervention. In addition, the steamer is located inside the inner pot. On the one hand, it is used to steam vegetables, buns, and other foods, preserving their original flavor and nutrients. On the other hand, when steaming rice, it separates the rice from the rice water. The rice water carries away some of the sugar from the rice, while some of the rice water is isolated inside the inner pot, thus achieving a sugar-reducing effect and lowering the sugar content of the rice, meeting the health-conscious dietary needs of some people. The lifting and moving assembly is driven by the lifting drive component to move the lifting and moving assembly and the steamer synchronously up and down relative to the bottom surface of the inner pot. The electrical connector is located on the bottom shell and is electrically connected to the lifting drive component. Preferably, the electrical connector is an upper coupler. The upper coupler is more conventional and mature in the application of rice cookers, and the electrical connection is more stable. Of course, the electrical connector can also adopt other structures, such as an electrical plug or an electrical socket. The heater is in close contact with the outer wall of the bottom surface of the inner pot and is electrically connected to the electrical connector. After the electrical connector is energized, the heater is powered on and heats up, the inner pot conducts heat, and the rice and other foods inside the inner pot are cooked faster. The heater is preferably a heating tube, such as a resistance wire heating tube, a ceramic heating tube, a resistance coil heating tube, or a quartz heating tube. Of course, other types of heaters, such as heating elements or electromagnetic heating elements, can also be used as needed. The heater can also be pressed against the outer surface of the inner wall of the inner 4 to improve the heating efficiency of the inner liner.

[0032] Based on the inner pot and steamer, a bottom shell, lifting device, and electrical connector are added, integrating the inner pot, steamer, bottom shell, lifting device, and electrical connector into a single unit. The lifting device and electrical connector are fixed to the bottom shell and inner pot, avoiding frequent disassembly and detachment between the lifting device and the inner pot. The structure is compact, the steamer lifting is more stable and reliable, and the sealing between the inner pot and the bottom shell is better, preventing water or steam from entering the bottom shell and improving safety. Moreover, the electrical connector provides power to the lifting device, enabling automatic lifting and lowering of the steamer through precise control of the lifting device, heater, and cooking program. This separates the rice and rice water, allowing the rice water to carry away some of the sugar from the rice and isolate some of the rice water in the inner pot, thus achieving a sugar-reducing effect on the rice and meeting the health-conscious dietary needs of some people. At the same time, no manual intervention is required, simplifying user operation and improving cooking efficiency.

[0033] In this embodiment, the lifting drive component includes a motor and a linkage reducer; the motor is connected to the bottom shell; the output shaft of the motor is connected to the linkage reducer and is also connected to the lifting and moving assembly. Specifically, the linkage reducer is installed on the outer wall of the bottom surface of the inner liner to enhance the connection stability between the motor and the linkage reducer between the bottom shell and the inner liner. The lifting and moving assembly includes a lead screw and a movable lifting member; the lower end of the lead screw is connected to the linkage reducer; the upper end of the lead screw passes through the bottom surface of the inner liner; the movable lifting member is adapted to be installed on the lead screw and is detachably connected to the steamer, and moves up and down relative to the bottom surface of the inner liner by rotating forward or backward driven by the motor. When adjusting the height of the steamer, after the electrical connector is energized, the motor operates, driving the lead screw to rotate via the linkage reducer. The forward and reverse rotation of the motor drives the lead screw to rotate in the same direction, causing the moving lifting component to move up and down relative to the bottom surface of the inner pot. This facilitates the synchronous up and down movement of the steamer relative to the bottom surface of the inner pot, thus achieving automatic lifting and lowering of the steamer. This separates the rice from the rice water, allowing the rice water to carry away some of the sugar from the rice while isolating some of the rice water into the inner pot, thereby reducing the sugar content of the rice and meeting the health-conscious dietary needs of some people. Of course, in other embodiments, where the overall structural volume is not a concern, a lifting cylinder or an electric lifting cylinder can be selected.

[0034] Preferably, a guide tube extending upwards is provided on the inner wall of the bottom surface of the bottom shell corresponding to the position through which the lead screw passes; the lead screw can rotatably pass into the guide tube; one end of the movable lifting component is adapted to be movably sealed and embedded in the guide tube and connected to the lead screw, while the other end passes through the guide tube and is detachably connected to the steamer. By setting the guide tube, the movable lifting component is well guided, and at the same time, the height difference between the guide tube and the bottom surface of the inner liner provides a good sealing and isolation effect, preventing water from entering the space between the inner liner and the bottom shell and causing short circuits in electrical components.

[0035] In this embodiment, the movable lifting component includes a movable slide and a lifting cylinder connected to the movable slide and movable in and out of the upper end of the lead screw. The movable slide is adapted to be installed on the lead screw and moves up and down relative to the bottom surface of the inner pot as the lead screw rotates in both directions, so that the lifting cylinder extends out or into the upper end of the guide tube. The steamer has a sleeve that can be fitted onto the guide tube or the lifting cylinder. By combining the movable slide and the lifting cylinder, the movable slide can move up and down relative to the bottom surface of the inner pot as the lead screw rotates in both directions, thereby allowing the lifting cylinder to extend out or into the upper end of the guide tube. This facilitates the automatic lifting and lowering of the steamer, separates the rice and rice water, and allows the rice water to carry away some of the sugar from the rice while isolating some of the rice water into the inner pot, thus achieving a sugar reduction effect on the rice and lowering its sugar content, meeting the health needs of some people. On the other hand, the sleeve design features a configuration where the lifting cylinder extends beyond the upper end of the guide tube, and the sleeve is fitted into the lifting cylinder. Alternatively, the lifting cylinder can be positioned inside the upper end of the guide tube, with the sleeve also fitted into the guide tube. This enhances the stability of the steamer within the inner liner. Furthermore, this design allows for a detachable connection between the steamer and the lifting and moving assembly, facilitating easy disassembly and cleaning. In other embodiments, the steamer can be detachably connected to the lifting and moving assembly using compatible snap-fit ​​or interlocking mechanisms.

[0036] Preferably, the guide tube, lifting cylinder, and sleeve are all cylindrical. This design simplifies the structural design and improves the vertical movement of the steamer.

[0037] To enhance the sealing between the movable lifting component and the guide tube, and to achieve a good sealing effect, preventing water or water vapor from entering the bottom shell from the guide tube, a sealing ring is fitted on the lifting cylinder that is adapted to and movably sealed to the inner wall of the guide tube.

[0038] In this embodiment, the bottom shell and the outer wall of the bottom surface of the inner liner are connected by a plurality of mounting supports. These mounting supports are evenly distributed around the central axis of the inner liner. This design of the mounting supports further enhances the stability of the connection between the bottom shell and the outer wall of the bottom surface of the inner liner.

[0039] In this embodiment, the bottom surface of the steamer is provided with several filter holes with a diameter of 0.5-1mm. The filter holes can be round, square, or even other shapes. This design is mainly for existing rice grains, whose diameter is generally greater than or equal to 1mm. This filter hole design can effectively prevent rice grains from passing through while achieving a good water filtration effect.

[0040] This utility model also discloses a rice cooker, including the steaming and cooking device of the rice cooker as described above, and further including an electronic control module, a body, and an electrical connection part adapted to and electrically connected to the electrical connection component (not shown in the accompanying drawings). The electrical connection part includes a coupler, etc. The body has a cavity adapted to house the steaming and cooking device of the rice cooker. The steaming and cooking device of the rice cooker is integrated as a whole and adapted to be installed in the cavity of the body. The electrical connection part is adapted to be electrically connected to the electrical connection component. The electronic control module controls the lifting drive and the heater to work. By precisely controlling the lifting device, the heater, and the cooking program, the automatic lifting and lowering of the steamer is achieved, separating the rice and rice water. The rice water carries away some of the sugar in the rice and isolates some of the rice water into the inner pot, thereby achieving a sugar reduction effect in the rice, reducing the sugar content of the rice, meeting the health needs of some people. At the same time, no manual intervention is required, simplifying user operation and improving cooking efficiency.

[0041] It should be noted that the heater, electrical control module, electrical connection part, and body are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. The specific implementation of this application may involve the use of software, but the software used is the most commonly used software by those skilled in the art and is not within the scope of protection of the claims of this patent application.

[0042] The working principle of this utility model is as follows:

[0043] To use, place the rice grains in the steamer and heat the water in the inner pot until the desired water level is reached. At this point, the rice grains in the steamer are submerged in the water inside the inner pot. Then, the steaming device of the rice cooker described above is installed as a whole in the cavity of the main body. The power connection part is connected to the power connector. After the pre-cooking work is completed, during the cooking process, the electric control module controls the lifting drive and the heater to work. The heater heats the water in the inner pot to boiling, dissolving the sugar in the rice in the steamer. After a certain period of time, the lifting device is activated, the motor works, and the screw is driven to rotate through the linkage reducer. The rotation of the motor drives the screw to rotate as well, causing the moving lifting part to move upward relative to the bottom of the inner pot. This causes the steamer to move upward relative to the bottom of the inner pot, separating the rice and rice water. The rice water carries away some of the sugar in the rice and isolates some of the rice water in the inner pot. The heater continues to work to cook the rice. In this way, the lifting device, heater and cooking program are precisely controlled to achieve the cooking of rice and the automatic lifting of the steamer, separating the rice and rice water, and separating some of the rice water from the rice and isolating some of the rice water in the inner pot.

[0044] In summary, this utility model embodiment provides a steaming device for a rice cooker, which has the following advantages: Based on the inner pot and steamer basket, a bottom shell, a lifting device, and an electrical connector are added, integrating the inner pot, steamer basket, bottom shell, lifting device, and electrical connector into a single unit. The lifting device and electrical connector are fixed to the bottom shell and inner pot, avoiding frequent disassembly and detachment between the lifting device and the inner pot. This results in a compact structure, more stable and reliable steamer lifting, and better sealing between the inner pot and bottom shell, preventing water or steam from entering the bottom shell and improving safety. Furthermore, the electrical connector provides power to the lifting device, enabling automatic lifting of the steamer basket through precise control of the lifting device, heater, and cooking program. This separates the rice and rice water, allowing the rice water to carry away some of the sugar from the rice and isolate some of the rice water within the inner pot, thus achieving a sugar-reducing effect on the rice and meeting the health needs of some individuals. Simultaneously, it requires no manual intervention, simplifying user operation and improving cooking efficiency.

[0045] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
