Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and particularly to a multi-pot integrated electric rice cooker.

Background Art

[0002] As a commonly used cooking utensil in households, an electric rice cooker usually has multiple cooking functions and can be used not only for cooking rice but also for making soup, steamed dishes, etc. However, conventional electric rice cookers often have a single-pot structure and can only cook one type of food at a time, making it difficult to meet the needs of users who want to cook multiple dishes simultaneously. Users have to purchase various electric rice cookers to cook multiple dishes simultaneously or cook multiple dishes separately using one electric rice cooker, which increases equipment costs, occupies more kitchen space, reduces cooking efficiency, and takes more time.

[0003] To meet the needs of users who want to cook multiple dishes simultaneously, the multi-layer electric rice cookers commonly seen in the current market improve cooking efficiency by stacking cooking spaces vertically. However, this design has problems such as uneven heat distribution between the upper and lower layers and the mixing of flavors of ingredients. In addition, it is also difficult for such multi-layer electric rice cookers to achieve independent temperature control for different ingredients and match individualized cooking programs, and some ingredients may be overcooked or not reach the ideal texture. Therefore, there is a need for an electric rice cooker structure that can achieve simultaneous cooking of multiple dishes, prevent the mixing of flavors, and enable independent temperature control.

[0024] Referring to Figures 1 to 4, this invention proposes a multi-pot integrated electric rice cooker.

[0025] In one embodiment of the present invention, the multiple integrated electric rice cookers mainly consist of a rice cooker casing 100, an upper lid component 200, a heating component 300, and a controller 400. The rice cooker casing 100, as the casing for the multiple integrated electric rice cookers, includes an upper rice cooker case 110 and a lower rice cooker case 120. The upper rice cooker case 110 is fixedly connected to the lower rice cooker case 120, and the connection method is not specifically limited in this embodiment, but can be implemented by methods such as bolt connection, snap connection, or welding. After the upper rice cooker case 110 is fixedly connected to the lower rice cooker case 120, a rice cooker chamber for housing the heating component 300 is formed inside the rice cooker casing 100. The upper rice cooker case 110 has three upper case through holes, each of which corresponds to one mounting position. The heating component 300 includes three cooking units: a first cooking unit 310, a second cooking unit 320, and a third cooking unit 330. Each cooking unit of the heating component 300 is housed in the rice cooker chamber, passing through a through-hole in the upper case, and is fixedly connected to the upper rice cooker case 110. The upper rice cooker case 110 separates and fixes the first cooking unit 310, the second cooking unit 320, and the third cooking unit 330, connecting them within their respective independent mounting positions, thereby ensuring no thermal interference between the cooking units. This enables independent operation of each cooking unit and prevents interference between multiple pots when they are operating simultaneously, further improving cooking efficiency and cooking quality.

[0026] The top lid component 200 includes three rice cooker lids 210 to cover each cooking unit of the heating component 300, each rice cooker lid 210 being able to be opened and closed independently, thereby allowing the user to easily open and close a specific cooking unit according to their actual needs. When the rice cooker lids 210 cover the corresponding cooking units of the heating component 300, they engage with the rice cooker upper case 110, forming a sealing structure to prevent steam leakage and ensure thermal efficiency and safety during cooking. The controller 400 is provided on the outer surface of the rice cooker upper case 110 and is fixedly connected to the rice cooker upper case 110, and is used to control the start / stop and operating modes of each cooking unit. The controller 400 is electrically connected to the heating component 300 and controls each cooking unit independently by receiving user operation commands. The controller 400 includes three sets of control units that independently control the first cooking unit 310, the second cooking unit 320, and the third cooking unit 330, respectively, to perform cooking operations. Each control unit in a set is equipped with an independent operating interface. The operating interface is located on the outer surface of the rice cooker's upper case 110, making it convenient for the user to control the operating status of each cooking unit. For example, the user can use the controller 400 to select the first cooking unit 310 to make rice or soup, or they can start the first cooking unit 310, the second cooking unit 320, and the third cooking unit 330 simultaneously to perform different cooking operations such as steaming, boiling, and simmering.

[0027] In this embodiment of the technology, multiple independent cooking units are provided separately in the upper case 110 of the rice cooker, and each cooking unit is combined with a control unit that controls each cooking unit independently. This enables independent control of multiple cooking tasks, improving the flexibility of use and cooking efficiency of multiple integrated electric rice cookers. Users can independently set the operating mode and time of each cooking unit according to their cooking needs for different ingredients, avoiding interference between them and preventing the mixing of flavors and the effects of heat cross-contamination.

[0028] In one selective embodiment, the volume of the pot 360 of the first cooking unit 310 is larger than the volume of the pot 360 of the second cooking unit 320, and the volume of the pot 360 of the second cooking unit 320 is equal to the volume of the pot 360 of the third cooking unit 330. By providing multiple cooking units and arranging pots 360 of different volumes, the user's need to cook multiple dishes simultaneously is met, making it particularly suitable for home meals and everyday multi-dish cooking scenarios. The large-volume pot 360 of the first cooking unit 310 can be used for simmering soups or steaming large quantities of staple foods, while the second and third cooking units 330 are suitable for small amounts of ingredients and can enable simultaneous cooking of porridge, side dishes, and rice. Each unit independently controls its temperature and does not interfere with each other, ensuring that the original flavors of the food do not diverge, improving energy efficiency and ease of use.

[0029] The first cooking unit 310, the second cooking unit 320, and the third cooking unit 330 each include an insulating cover 340, a heating disc 350, and a pot 360, with the opening of the insulating cover 340 fixedly connected to the upper case 110 of the rice cooker. The heating disc 350 is housed within the insulating cover 340 and electrically connected to the corresponding control unit, with one side of the heating disc 350 fixedly connected to the bottom wall of the insulating cover 340. The pot 360 is detachably positioned on the side of the heating disc 350 away from the bottom wall of the insulating cover 340, and the bottom of the pot 360 is in close contact with the heating disc 350. The pot 360 is heated uniformly via the heating disc 350, achieving highly efficient heat conduction. By covering the outside of the heating disc 350 and the pot 360 with the insulating cover 340, heat escape to the outside is effectively blocked, increasing thermal efficiency, lowering the temperature of the casing, and avoiding the effects of heat crossover between each cooking unit.

[0030] In this embodiment, the side of the heating disc 350 that contacts the bottom of the pot 360 has a planar structure, thereby ensuring close contact between the two surfaces and maximizing heat conduction efficiency. On the side of the heating disc 350 away from the pot 360, spirally distributed annular heating tubes are provided. These annular heating tubes extend from the center to the outer circumference along the bottom surface of the heating disc 350, ensuring uniform heat distribution and avoiding scorching of food due to localized overheating and uneven heat distribution. Through an electrical connection between an independent control unit and the heating disc 350, the controller 400 can precisely adjust the heating power and operating time of each cooking unit, enabling individualized temperature control management for different ingredients.

[0031] Furthermore, the upper case 110 of the rice cooker has a flange 111 that extends upward through a through-hole in the upper case and supports the pot 360. The flange 111 fits the outer edge of the pot 360, thereby ensuring a stable position of the pot 360 and preventing it from tipping over. In this embodiment, the height of the flange 111 is not specifically limited and can be adjusted according to the height of the pot 360, thereby ensuring sufficient contact between the bottom of the pot 360 and the heating disc 350. A flange portion 361 is formed at the opening of the pot 360, extending outward along the radial direction, and the flange portion 361 abuts against the flange 111. The fitting of the flange portion 361 and the flange 111 further improves the stability of the position of the pot 360 and ensures complete separation of the pots 360 of different cooking units, preventing the mixing of flavors due to spillage of liquid and the crossing of steam, as well as preventing the effects of heat crossing between different pots 360.

[0032] The upper case 110 of the rice cooker has hooks 112 that extend downward through the upper case through-holes to support the heat insulating cover 340. The outer wall of the heat insulating cover 340 is provided with hanging grooves 341 that engage with the hooks 112 and are distributed circumferentially, so that the hooks 112 engage with the hanging grooves 341. The engagement connection between the hooks 112 and the hanging grooves 341 ensures stable mounting of the heat insulating cover 340 on the upper case 110 of the rice cooker. The engagement structure between the hooks 112 and the hanging grooves 341 enables the heat insulating covers 340 of each cooking unit to be fixed separately from each other, ensuring heat sealing and structural stability during independent operation of each cooking unit, and effectively avoiding the exchange of heat and steam.

[0033] Specifically, the hook 112 is L-shaped, with its horizontal segment used to support the hanging groove 341 of the insulation cover 340, and its vertical segment formed by the extension of the rice cooker upper case 110 downwards and molded integrally with the rice cooker upper case 110 to enhance structural strength. The hanging groove 341 is opened at the upper end of the outer wall of the insulation cover 340, and its shape fits the L-shaped hook 112, enabling the insulation cover 340 to be fixedly attached to the rice cooker upper case 110 by hanging the insulation cover 340 on the hook 112 along the vertical direction during assembly.

[0034] Selectively, a temperature sensor 410, electrically connected to a controller 400, is fitted onto the heating disc 350. The temperature sensor 410 is used to monitor temperature changes at the bottom of the pot 360 in real time and to feed back temperature data to the controller 400, thereby achieving closed-loop temperature control. By accurately sensing the actual heating temperature, the controller 400 can dynamically adjust the heating power based on a preset program, avoiding overheating or underheating, and further improving cooking efficiency and energy utilization. The temperature sensor 410 is fitted into the central region of the heating disc 350 on the side closest to the pot 360, ensuring that the temperature measurement position is at a critical point in the heat transfer path and improving the accuracy of temperature measurement.

[0035] On the side of the heating disc 350 that connects to the heat insulation cover 340, support feet 351 are provided to support the heating disc 350 and the heat insulation cover 340, forming a gap. There are at least three support feet 351, which are distributed at intervals around the outer circumference of the heating disc 350. Screw holes are provided at the ends of the support feet 351 that are away from the heating disc 350, and screws are used to fasten the support feet 351 to the bottom of the heat insulation cover 340, thereby fixing the heating disc 350 and the heat insulation cover 340 together. The support feet 351 form a gap between the heat insulation cover 340 and the heating disc 350, and this gap exists as an air insulation layer, blocking heat from being directly conducted to the heat insulation cover 340. The support feet 351 are integrally molded with the heating disc 350 to ensure structural integrity in long-term high-temperature environments. The gap, when combined with the insulation cover 340, forms a double thermal barrier structure as a whole, further preventing heat transfer between different cooking units and maintaining independent temperature control for each cooking unit. Specifically, the height of the support feet 351 is 3-5 mm, which ensures sufficient thickness of the air insulation layer and maintains structural stability.

[0036] Each control unit includes a display module and control buttons for inputting cooking commands. The display module is used to display information such as the current cooking mode, temperature status, and remaining time in real time, making it convenient for the user to intuitively understand the operating status of each cooking unit. The control buttons support independent setting of each cooking parameter, and the control buttons on each control unit enable synchronous operation of multiple cooking tasks, ensuring that each cooking unit operates as needed without interference. The controller 400 stores multiple sets of pre-set cooking curves, and by combining them with data fed back from the temperature sensor 410, it can dynamically adjust the heating policy and achieve refined cooking of different ingredients such as rice, porridge, and soup. Each control unit is isolated via an independent circuit to avoid signal crosstalk and ensure the sensitivity and reliability of the operation response. The upper case 110 of the rice cooker is provided with openings corresponding to the control buttons and display module to expose the visible areas of the control button surfaces and display modules, ensuring operation touch sensitivity and clear reading of information. The multiple integrated electric rice cookers further include a transparent lid plate 113, which covers the opening and is fixedly connected to the upper rice cooker case 110. The transparent lid plate 113 and the upper rice cooker case 110 are fixed together via a sealing adhesive, preventing water vapor and oil stains from entering the circuit area of ​​the internal controller 400, thereby improving the overall safety and durability of the machine.

[0037] For example, when a user inputs "soup" mode to the control unit, the control unit recalls the corresponding cooking curve and, in combination with real-time feedback from the temperature sensor 410, controls the heating disk 350 of the first cooking unit 310 to maintain a gentle simmer of soup over low heat. Furthermore, when the user activates the "rice" function of the second cooking unit 320 and the "porridge" function of the third cooking unit 330, it is possible to ensure that the three cooking units do not interfere with each other. By executing each program independently, multiple task operations such as simultaneous cooking of soup and rice, or simultaneous cooking of porridge and stew can be achieved.

[0038] The multi-component electric rice cooker further includes a rice cooker lid connecting member 500 that movably connects the rice cooker lid 210 to the rice cooker upper case 110. The rice cooker lid connecting member 500 employs a detachable hinge structure, making it easy for the user to attach and detach the rice cooker lid 210 for cleaning. The rice cooker lid connecting member 500 includes a hinge shaft 510 and a torsion spring 520. The torsion spring 520 is fitted onto the hinge shaft 510, and the elastic action of the torsion spring 520 provides a smooth damping effect when opening and closing the rice cooker lid 210, preventing impact damage caused by rapid dropping due to gravity. Both ends of the hinge shaft 510 are fixed to the rice cooker upper case 110, ensuring that the connection structure is stable and secure. One end of the torsion spring 520 is inserted into the rice cooker lid 210 from the rear end and fixedly connected to the rice cooker lid 210, and the other end of the torsion spring 520 is inserted into the upper case 110 of the rice cooker and fixedly connected to the upper case 110 of the rice cooker. When the user opens the rice cooker lid 210, the torsion spring 520 releases its elastic potential to lift the rice cooker lid 210, and when the user closes the rice cooker lid 210, the torsion spring 520 is compressed and stores its elastic potential. The synergistic effect of the torsion spring 520 and the hinge shaft 510 reduces the opening and closing speed of the rice cooker lid 210 and prevents abnormal noise and structural loosening due to collisions.

[0039] A storage groove 211 for housing the lid opening button is provided at the front end of the rice cooker lid 210, and the lid opening button is fitted into the storage groove 211. A top snap is provided at the end of the lid opening button that engages with the upper case 110 of the rice cooker. The upper case 110 of the rice cooker extends upward and has a locking ring 114 that engages with the top snap. When the lid opening button is pressed while the rice cooker lid 210 is covering the upper case 110 of the rice cooker, the top snap disengages from the locking ring 114, unlocking the locked state of the rice cooker lid 210 and the upper case 110 of the rice cooker, and the lid opens. When the lid opening button is loosened and the rice cooker lid 210 is covered with the upper case 110 of the rice cooker, the top snap engages with the locking ring 114 under the action of elastic force, and the lid closes.

[0040] Furthermore, a double-layer sealing structure is provided inside the rice cooker lid 210, and the rice cooker lid 210 includes a sealing pad, a steam valve, and a sealing ring. The sealing pad is fitted to the inner edge of the rice cooker lid 210 on the side closer to the heating component 300, and when the rice cooker lid 210 covers the heating component 300, it tightly adheres to the upper edge of the pot 360, forming the first sealing barrier. The dimensions of the sealing pad are not specifically limited in this embodiment and can be adapted to the opening size of the pot 360, ensuring a tight seal and preventing steam leakage. The steam valve is embedded in the rice cooker lid 210 and controls the pressure inside the pot and steam discharge through its internal channel, automatically adjusting the exhaust volume in a high-temperature, high-pressure environment and avoiding safety hazards due to pressure buildup. The sealing ring is fitted to the outside of the steam valve, and the outer circumference of the sealing ring and the rice cooker lid 210 are connected by an interference fit, ensuring that there is no gap for leakage between the steam valve and the rice cooker lid 210, forming the second sealing barrier. The synergistic effect of the two-layer sealing improves the thermal efficiency and safety of the heating component 300 during cooking in the rice cooker, and prevents the risk of burns due to the leakage of high-temperature steam.
