Description

Technical Field

[0001] This utility model relates to the field of electric slow cooker technology, and in particular to an electric slow cooker with a dual-mode structure. Background Technology

[0002] Currently, most cooking appliances on the market suffer from limited functionality. Taking slow cookers as an example, they are mainly divided into two categories based on their heat conduction method: water-cooled slow cookers and air-cooled slow cookers. Water-cooled slow cookers transfer heat through water; when simmering soups or stewing meat, the heating speed is slow, and the temperature of the inner pot is relatively low, preserving the nutrients of the ingredients and producing a clear, sweet broth, thus meeting the refined cooking needs of users. Air-cooled slow cookers, on the other hand, heat the ceramic body directly through an outer heat conductor, either through air transfer or by contact between the ceramic body and the heat conductor. The ceramic body reaches a high temperature and heats up quickly, suitable for stewing that requires rapid and high-temperature cooking, resulting in a rich and flavorful broth. While the two types of slow cookers have clear functional divisions, they are relatively limited in their application.

[0003] For the user, both stewing methods will be used at different times.

[0004] However, for users who need both fine stewing and quick stewing, purchasing these two types of equipment separately not only increases additional procurement costs but also occupies already limited kitchen space, resulting in a double waste of resources and space.

[0005] To address this shortcoming, some multi-functional electric slow cookers have gradually emerged on the market. However, these products still have significant drawbacks, especially when switching between different cooking modes. Users need to manually select the slow cooker or stew pot function at uncertain times, which lacks an intelligent experience and requires users to invest extra time in operation, resulting in insufficient ease of use and difficulty in effectively improving the user experience. They have failed to truly solve the core problems caused by traditional single-function slow cookers.

[0006] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0035] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0036] like Figure 1-11 As shown, this embodiment provides an electric slow cooker with a dual-mode structure, including a slow cooker assembly 1, a stewing pot assembly 2, an operation panel 3, a heating element 4, an NTC device 5, and a control system. The slow cooker assembly 1 includes an inner shell 11, an outer shell 12, a slow cooker lid assembly 7, a first sealing ring 13, and a connecting assembly 6. The inner shell 11 is fixedly disposed within the outer shell 12. The upper end of the inner shell 11 and the upper end of the outer shell 12 are connected together by the first sealing ring 13 and connected to the slow cooker lid assembly 7 by the connecting assembly 6. The inner shell 11 has a heating chamber 111 inside. The bottom of the inner shell 11 includes a stewing pot platform 112 that protrudes from the middle of the heating chamber 111 and a water storage part 113 on the outer periphery of the stewing pot platform 112. The stewing pot assembly 2 is detachably disposed in the heating chamber 111. The heating element 4 is disposed outside the inner shell 11. The operation panel 3 is disposed on the outer shell 12. The NTC device 5 is disposed at the bottom of the water storage part 113. The control system is electrically connected to the heating element 4, the operation panel 3 and the NTC device 5 respectively.

[0037] The heating component 4 includes a first heating element 41 and a second heating element 42, wherein the first heating element 41 is disposed at the bottom of the inner shell 11, and the second heating element 42 is sleeved on the outer periphery of the side wall of the inner shell 11.

[0038] This invention proposes an electric slow cooker with a dual-mode structure, which has at least two working modes and can intelligently identify and switch to the appropriate mode. It combines double-boiling and air-boiling functions into one product, making it convenient for users and enhancing the user experience.

[0039] Furthermore, the heating component 4 also includes an anti-dry-burning device 43. A fixing structure 14 is provided at the bottom of the inner shell 11. The fixing structure 14 fixes the first heating element 41 to the bottom of the stew pot stand 112. The NTC device 5 and the anti-dry-burning device 43 are respectively fixed to the outside of the water storage part 113 through the fixing structure 14.

[0040] The outer diameter of the water storage section 113 is larger than the outer diameter of the upper part of the inner shell 11 to form a water storage space. The second heating element 42 is annular and fixed to the outer periphery of the side wall of the upper part of the inner shell 11.

[0041] The stewing stand 112 is used to fix the stewing pot assembly 2, and the first heating element 41 is fixed to the bottom of the stewing stand 112, which can quickly transfer heat to the bottom of the stewing pot assembly 2. The water storage part 113 is provided so that the user can easily put water into the inner shell 11, thereby providing the conditions for realizing the double-boiling function.

[0042] Furthermore, an inverted "U"-shaped edging 114 is formed at the top of the inner housing 11. The connecting assembly 6 includes a connecting ring 61 and a second sealing ring 62. The lower side of the connecting ring 61 has a snap-fit ​​groove 611 adapted to the edging 114. The snap-fit ​​groove 611 is fitted onto the edging 114. A support portion 612 is provided on one side of the snap-fit ​​groove 611, and the second sealing ring 62 is connected to the support portion 612. The connecting assembly 6 connects the inner housing 11 and the outer housing 12 together. The second sealing ring 62 helps to enhance the sealing between the inner housing 11 and the connecting ring 61. The design of the support portion 612 strengthens the connection between the connecting ring 61 and the second sealing ring 62.

[0043] Furthermore, the stewing pot assembly 2 includes a stewing pot 21 and a stewing pot lid 22. The stewing pot 21 is provided with a retaining edge 211 and is engaged with the second sealing ring 62 through the retaining edge 211. The stewing pot lid 22 is installed on the retaining edge 211.

[0044] A groove 621 is provided on the outer side of the second sealing ring 62, and the support part 612 is inserted into the groove 621. A support strip 622 is provided on the inner side of the second sealing ring 62 to the top. Several support strips 622 are spaced apart on the inner side of the second sealing ring 62. The support strips 622 are used to support the stew pot assembly 2. A channel is formed between two adjacent support strips 622. Water vapor in the inner shell 11 can flow to the stew pot lid assembly 7 through the channel, or condensate at the stew pot lid assembly 7 can flow back to the inner shell 11 through the channel.

[0045] The support strip 622 serves two purposes: firstly, it supports the stew pot assembly 2, and secondly, it allows steam to pass through the channel within the stew pot assembly 1. When the water in the water storage section 113 is heated, the steam moves towards the stew pot lid 22, enveloping the stew pot assembly 2 in heat. When the steam inside the stew pot lid assembly 7 and on the stew pot lid 22 cools and condenses, it flows back to the water storage section 113 through the channel. The second sealing ring 62 achieves both external sealing and unobstructed internal airflow.

[0046] Furthermore, the stew pot lid assembly 7 includes an inner lid 71, an outer lid 72, and a positioning ring 73. The inner lid 71 and the outer lid 72 are connected by the positioning ring 73. A third sealing ring 74 is provided at the lower bottom of the positioning ring 73. The third sealing ring 74 is provided with a groove 741, and the bottom end of the inner lid 71 is inserted into the groove 741.

[0047] Because there is space between the inner cover 71 and the outer cover 72, they do not fit together. The positioning ring 73 facilitates the connection between the ends of the inner cover 71 and the outer cover 72. The space between the inner cover 71 and the outer cover 72 facilitates the arrangement of the exhaust assembly 8 described below.

[0048] Specifically, the connecting ring 61 further includes a limiting groove 613, with several limiting grooves 613 spaced apart on the upper end of the connecting ring 61. The positioning ring 73 is provided with a limiting hole 731. The stew pot lid assembly 7 also includes a limiting member 75, which is provided with a limiting post 751. The limiting post 751 passes through the limiting hole 731 and can engage with the limiting groove 613. This arrangement allows the limiting post 751 on the stew pot lid assembly 7 to connect better with the connecting ring 61. On the one hand, it helps the user to align and close the stew pot lid assembly 7. On the other hand, it strengthens the connection between the stew pot lid assembly 7 and the inner shell 11 and the outer shell 12, ensuring good sealing of the electric stew pot exterior.

[0049] Preferably, the stew pot lid assembly 7 is provided with an exhaust assembly 8 and a handle assembly 9. The handle assembly 9 is located in the middle of the stew pot lid assembly 7, and the exhaust assembly 8 is located on one side of the handle assembly 9. The exhaust assembly 8 includes a steam part 81, an exhaust part 82, a micro-pressure exhaust valve 83, and a sealing ring 84. The steam part 81 is located on the inner cover 71, and a plurality of exhaust holes 811 are distributed in the middle of the steam part 81. The exhaust part 82 is located on the outer cover 72 at a position matching the steam part 81. The lower end of the exhaust part 82 is connected to the steam part 81, and the upper end is fitted with the micro-pressure exhaust valve 83. The sealing ring 84 is provided between the micro-pressure exhaust valve 83 and the exhaust part 82.

[0050] An installation ring 821 is provided on the upper side of the exhaust section 82. The micro-pressure exhaust valve 83 includes a valve body 831, a connecting part 832, and a hook part 833. The valve body 831 is connected to the hook part 833 through the connecting part 832. The lower end of the hook part 833 is an "L"-shaped outer hook 834. The connecting part 832 and the hook part 833 pass through the installation ring 821. The installation ring 821 can limit the range of motion of the outer hook 834. A sealing ring groove 835 is provided between the bottom of the valve body 831 and the outer periphery of the connecting part 832. The sealing ring 84 is disposed in the sealing ring groove 835, thereby sealing the gap between the installation ring 821 and the micro-pressure exhaust valve 83.

[0051] The exhaust assembly 8 is designed to ensure the normal operation of the electric slow cooker. When the gas pressure inside the slow cooker is low, the sealing ring 84 is between the micro-pressure exhaust valve 83 and the exhaust section 82, thus sealing the exhaust assembly 8. When the gas pressure inside the slow cooker is high, the gas pressure pushes the micro-pressure exhaust valve 83 upward, and the outer hook 834 hooks the mounting ring 821, allowing water vapor to be released from the micro-pressure exhaust valve 83.

[0052] from Figure 12 As can be seen, the above objectives are achieved through the following control methods.

[0053] A control method for the above-mentioned electric slow cooker with a dual-mode structure, the control method comprising:

[0054] Power is connected, and the program starts.

[0055] The system checks if the NTC device is open-circuited. If the NTC device is open-circuited, the slow cooker is put into standby mode; if the NTC device is closed-circuited, the process proceeds to the next step. This stage is preferably set to perform the check for 5 seconds. Detecting whether the NTC device is open-circuited helps the system detect the presence of an NTC device inside the slow cooker, which is a crucial step for subsequent intelligent control.

[0056] The system controls the first and second heating elements to operate simultaneously for a first preset time; after detecting the presence of the NTC device, the system begins operation. This detection phase is preferably set to 60 seconds.

[0057] The system determines whether the temperature rise of the NTC device exceeds a temperature rise threshold. If the temperature rise is less than the threshold, the slow cooker is put into standby mode. If the temperature rise exceeds the threshold, the process proceeds to the next step. This stage primarily checks whether the NTC device is installed correctly. A temperature rise threshold needs to be set at this stage, preferably at least 10°C above the threshold.

[0058] The system controls the first and second heating elements to work simultaneously for a second preset time. After the above steps confirm that the NTC device is functioning normally, the system officially enters the intelligent cooking stage.

[0059] The system detects and determines the appropriate operating mode based on the temperature detected by the NTC device. If the NTC device temperature is below 99℃, or if the temperature remains between 99℃ and 105℃ within the program-set time, the slow cooker enters the double-boiling mode. If the NTC device temperature is above 105℃, and the temperature remains above 105℃ for longer than the program-set time, the slow cooker enters the air-cooking mode. The system intelligently selects the appropriate operating mode based on the temperature detected by the NTC device. This eliminates the need for users to periodically operate the slow cooker according to the food's cooking progress, improving the user experience.

[0060] Furthermore, the control method for the double-boiling working mode:

[0061] The system starts timing. A heating time of 40 to 210 minutes is preferred.

[0062] The second heating element is controlled to stop heating, while the first heating element heats according to the program-defined method.

[0063] The temperature of the NTC device is monitored to determine if there is water in the heating chamber. This prevents the process from failing due to insufficient water.

[0064] If the temperature of the NTC device is below 99°C, or if the temperature remains between 99°C and 105°C within the program-defined time, it is determined that there is water in the heating chamber, and the first heating element continues to be controlled to heat according to the program definition.

[0065] If the temperature of the NTC device is higher than 105°C and the time the temperature is higher than 105°C exceeds the program-set time, it is determined that there is no water in the heating chamber. Then, the first heating element and the second heating element are controlled to heat according to the program-defined method to control the temperature of the heating chamber within the program-set range.

[0066] Once the timer is complete, control the electric slow cooker to stop heating.

[0067] The buzzer sounds, indicating that the electric slow cooker is in standby mode. When cooking is complete, the buzzer sounds again to remind the user and the food is kept warm.

[0068] Furthermore, the control method for the air-stewing working mode:

[0069] The system starts timing. A heating time of 40 to 210 minutes is preferred.

[0070] The first and second heating elements are controlled to heat according to the temperature of the NTC device and in a programmed manner, keeping the temperature of the heating chamber within the programmed range. The user can pre-select a suitable heating mode on the control panel as needed, and the system then cooks the food according to the corresponding heating mode.

[0071] Once the timer is complete, control the electric slow cooker to stop heating.

[0072] The buzzer sounds, indicating that the electric slow cooker is in standby mode. When cooking is complete, the buzzer sounds again to remind the user and the food is kept warm.

[0073] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
