Description

Technical Field

[0001] This application relates to the field of heating equipment technology, and in particular to a heating container. Background Technology

[0002] In modern home appliance design, to meet users' demand for large amounts of hot water, many devices with water heating functions are equipped with large-capacity heating tanks. However, this design choice brings significant technical challenges, especially in ensuring water temperature uniformity. Because the heating element is fixed in position, the heating process often results in significant temperature differences between different areas within the heating tank: areas closer to the heating element are warmer, while areas farther away are cooler. This not only affects the temperature stability of the water output, leading to a poor user experience (such as fluctuating temperatures during continuous water use), but also increases the complexity of product design and optimizing the outlet layout.

[0003] Furthermore, uneven temperature distribution within the water tank can lead to more serious consequences. For example, some areas may fail to reach the necessary disinfection or sterilization temperatures, creating conditions for the growth of bacteria and other microorganisms, thus threatening water quality safety. Simultaneously, overheating in some areas while underheating in others results in low energy efficiency and may accelerate the aging process of heating elements, shortening their lifespan. Long-term uneven temperature distribution can also exacerbate the aging of internal tank materials due to thermal expansion and contraction, increasing the risk of seal failure, leaks, and consequently, higher maintenance costs.

[0004] Although introducing temperature sensors can monitor temperature changes inside the water tank, this method only provides limited information, cannot achieve comprehensive coverage, and cannot fundamentally solve the problem of uneven heating temperature. Summary of the Invention

[0005] To address at least one drawback of the prior art, this application provides a heating container, comprising:

[0006] A container shell, which encloses a cavity for holding a liquid to be heated; the cavity is divided into multiple interconnected subspaces.

[0007] A heating device is disposed inside the cavity;

[0008] A thermal image acquisition device is disposed outside the cavity, and the field of view of the thermal image acquisition device covers the cavity; the thermal image acquired by the thermal image acquisition device is used to indicate a target subspace among the plurality of subspaces; the temperature difference between the liquid to be heated in the target subspace and the liquid to be heated in the subspaces other than the target subspace among the plurality of subspaces is greater than a preset temperature difference;

[0009] A stirring device, comprising a plurality of stirrers corresponding one-to-one with the plurality of subspaces, each stirrer being disposed inside a corresponding subspace;

[0010] For each of the plurality of subspaces, a stirrer in at least one adjacent subspace of the subspace is configured to be operational when the subspace is the target subspace indicated by the thermal image; the adjacent subspaces of the subspace are the subspaces that are adjacent to the subspace in the plurality of subspaces.

[0011] Optionally, for each edge subspace among the plurality of subspaces, the stirrer within the edge subspace is configured to be operational when the edge subspace is the target subspace indicated by the thermal image; the number of adjacent subspaces of the edge subspace is less than or equal to the number of adjacent subspaces of any subspace other than the edge subspace among the plurality of subspaces.

[0012] Optionally, the plurality of stirrers are configured to operate when the number of target subspaces indicated by the thermal image is greater than a preset number.

[0013] Optionally, the stirrer includes a drive motor, a stirring rod, and blades; a plurality of blades are distributed along the axial direction of the stirring rod and disposed on the stirring rod; the drive end of the drive motor is connected to one end of the stirring rod and is used to drive the stirring rod to rotate, so that the stirring rod drives the blades to rotate around the stirring rod.

[0014] Optionally, the multiple blades on the stirring rod are arranged in an alternating pattern.

[0015] Optionally, the plurality of subspaces are distributed along a first direction, which is perpendicular to the axial direction of the stirring rod.

[0016] Optionally, for each of the plurality of subspaces, the stirrer in the subspace and the stirrer in the adjacent subspace are disposed opposite to each other on the inner wall of the container shell along the axial direction of the stirring rod.

[0017] Optionally, the heating container further includes a water inlet pipe, one end of which is used to connect to a water source, and the other end of which forms multiple branch pipes, which are respectively connected to the cavity.

[0018] Optionally, the container shell includes a first side and a second side arranged opposite each other in a vertical direction, the first side being higher than the second side in a vertical direction, and the plurality of branch pipes being evenly distributed on the first side.

[0019] Optionally, the first direction is the vertical direction.

[0020] By adopting the above technical solution, this application has the following beneficial effects:

[0021] This application provides a heating container. The container's cavity is divided into multiple sub-spaces, and a thermal image acquisition device is installed outside the cavity to identify temperature differences between the sub-spaces. A stirrer is configured inside each sub-space. When the temperature difference between a sub-space and other sub-spaces is detected to be greater than a preset temperature difference, the stirrer in the adjacent sub-space accelerates the mixing of the liquid in that sub-space with the liquid in its neighboring sub-spaces, thereby uniformly heating the liquid inside the container. Through precise monitoring by the thermal image acquisition device and targeted stirring by the stirrer, the consistency of the liquid temperature inside the container is ensured, reducing the time required to reach a uniform temperature, thus improving heating efficiency and enhancing the user experience. Uniform temperature distribution reduces the risk of material aging due to localized high temperatures, helping to extend the service life of the heating element and the entire device. Overheating is avoided, reducing unnecessary energy consumption and optimizing energy utilization during the heating process.

[0032] refer to Figure 1-2 This application provides a heating container, comprising:

[0033] The container shell 1 encloses a cavity for holding the liquid to be heated; the cavity is divided into multiple interconnected sub-spaces 2. Specifically, the material of the container shell 1 needs to have good heat resistance and chemical resistance to adapt to different heating liquids and environmental conditions. Commonly used materials include stainless steel, aluminum alloys, and special plastics. For example, stainless steel is the preferred material due to its corrosion resistance and high-temperature resistance, but its cost is relatively high; aluminum alloys are favored due to their lightweight and good thermal conductivity, but their chemical resistance is relatively poor. The wall thickness of the container shell 1 directly affects its strength and pressure resistance. Based on the maximum pressure and temperature that may be generated during liquid heating, the optimal wall thickness design is determined through finite element analysis to ensure the safety and durability of the container. To reduce heat loss and improve energy efficiency, the insulation design of the container shell 1 is equally important, which can be achieved by adding an insulation layer or using materials with high thermal resistance. For example, using polyurethane foam as insulation material can effectively reduce heat loss and improve heating efficiency. Specifically, the cavity is virtually divided into multiple subspaces 2. These subspaces 2 are not physically isolated from each other, but are treated as independent areas in the control logic to allow for individual temperature monitoring and management of the liquid in different areas. A water outlet pipe 13 communicating with the cavity is provided on the container shell 1, along with a water outlet valve 14. When the user draws water, the water outlet valve 14 opens to release water. An exhaust pipe 15 communicating with the cavity is provided on the container shell 1, along with an exhaust valve 16. When heating to boiling, the exhaust valve 16 opens, allowing the high-pressure steam inside the cavity to escape through the exhaust pipe 15, ensuring that the heating container does not expand and leak. Following the conventional placement of the heating container, the water outlet pipe 13 is positioned near the bottom of the heating shell 1, and the exhaust pipe 15 is positioned near the top of the heating shell 1.

[0034] A heating device 3 is installed inside the cavity and is used to heat the liquid to be heated within the cavity. In practice, following the conventional placement of heating containers, the heating device 3 is typically located at the bottom of the container 1 inside the cavity. The heating device 3 can be a circular heating plate. Specifically, the heating device 3 can employ electric heating, gas heating, or steam heating. The surface material of the heating device 3 has good thermal conductivity to reduce heat loss. The power configuration of the heating device 3 needs to be determined based on the capacity of the heating container and the heating requirements; specifically, the power of the heating device 3 should match the heating requirements of the container. Excessive power may lead to energy waste and overheating, while insufficient power will not meet the heating requirements. The required heating power can be determined by calculating the mass of the liquid, its specific heat capacity, and the target temperature difference. The heating device is equipped with a temperature control system, which maintains the target temperature by adjusting the power output of the heating element.

[0035] A thermal image acquisition device 4 is located outside the cavity, and its field of view covers the cavity. The thermal images acquired by the thermal image acquisition device 4 are used to indicate the target subspace among multiple subspaces 2. The temperature difference between the liquid to be heated in the target subspace and the liquid to be heated in other subspaces 2 is greater than a preset temperature difference. Specifically, the thermal image acquisition device 4 is a key component of the heating container. It uses infrared thermal imaging technology to measure the surface temperature of the object without direct contact, monitors the temperature distribution inside the heating container in real time, and provides temperature feedback data. This data is used to determine the temperature difference between each subspace 2, and the control system can identify the target subspace whose temperature is higher or lower than other subspaces. Infrared thermal imaging technology is based on the relationship between the infrared radiation emitted by an object and its temperature. It captures thermal radiation signals through a highly sensitive infrared detector and converts them into a visualized thermal image. Infrared thermal imaging technology can provide an intuitive image of the temperature field and has advantages such as non-contact measurement, fast response, and wide coverage. In the heating container, infrared thermal imaging technology can monitor the temperature of each subspace 2 in real time, ensuring the uniformity and efficiency of the heating process. In practice, the thermal image acquisition device 4 can be set as an infrared camera device, which has a fast measurement speed and can obtain temperature readings in real time.

[0036] In practical implementation, the configuration of the thermal image acquisition device 4 needs to consider its installation position outside the cavity, field of view, and interface with the control system. Following the conventional placement of heating containers, to ensure the thermal image acquisition device can cover the entire cavity, it is usually installed on the top or side of the cavity to obtain the optimal field of view and minimize temperature measurement errors. The field of view of the thermal image acquisition device 4 needs to be wide enough to cover all subspaces 2. The size of the field of view directly affects the comprehensiveness and accuracy of temperature monitoring. A suitable thermal image acquisition device 4 is selected based on the size and shape of the cavity to ensure its field of view meets the monitoring requirements. The thermal image acquisition device 4 needs to be connected to the control system of the heating container to achieve real-time transmission and processing of temperature data. This is usually achieved through wired or wireless means, ensuring the stability and real-time performance of data transmission. The acquired thermal image data needs to be processed by specific algorithms to extract temperature information and indicate the target subspace. Thermal image data processing includes steps such as image enhancement, noise filtering, and temperature extraction. Through these processes, the quality of the thermal image can be improved, environmental interference reduced, and temperature information of each subspace 2 accurately extracted. This allows the system to identify and indicate the temperature difference between each subspace 2. When the temperature difference between a certain subspace 2 and other subspaces 2 exceeds a preset temperature difference, that subspace 2 is identified as the target subspace, and the system will automatically adjust the working state of the stirring device. In specific implementation, an image processing system can be set up inside the thermal image acquisition device 4 to identify the target subspace and activate the corresponding stirrer 2 for the target subspace.

[0037] The stirring device includes multiple stirrers 5 corresponding to multiple subspaces 2, each stirrer 5 being disposed inside its respective subspace 2. Specifically, the layout of the stirrers 5 within the subspace needs to consider the dynamic characteristics of the liquid flow. The placement and angle of the stirrers 5 should promote liquid circulation and avoid dead zones and eddies, ensuring the uniformity of liquid temperature and composition throughout the subspace. In practice, paddle, turbine, and anchor stirrers can be used. The specific type of stirrer 5 selected depends on the physical properties of the liquid and the purpose of stirring. For example, paddle stirrers are suitable for mixing low-viscosity liquids, while anchor stirrers are suitable for stirring high-viscosity liquids. The material of the stirrers 5 needs to be selected based on the chemical properties of the liquid to ensure corrosion resistance and stability. Commonly used materials include stainless steel, titanium alloys, and special plastics. When a subspace is designated as the target subspace by a thermal image acquisition device, the stirrers in at least one adjacent subspace of that subspace will automatically enter the working state, ensuring timely mixing of the liquid during the heating process.

[0038] For each of the multiple subspaces 2, at least one agitator 5 in an adjacent subspace is configured to operate when the subspace 2 is identified as the target subspace by the thermal image. The adjacent subspaces are those adjacent to the target subspace 2. Specifically, each subspace 2 is equipped with a corresponding agitator 5. When a subspace 2 is identified as the target subspace, at least one agitator 5 in an adjacent subspace of that subspace 2 is activated and begins operation. The agitator, in operation, stirs the liquid, promoting mixing between the liquid in the target subspace and the liquid in its adjacent subspaces. This helps reduce temperature differences, allowing heat to transfer from one area to another, thus achieving a more uniform temperature distribution. The entire system forms a closed-loop control system: the thermal image acquisition device provides feedback, the control system makes adjustments, and the agitator performs actions; all three work together to maintain the temperature uniformity of the liquid within the cavity.

[0039] Specifically, in this embodiment, temperature uniformity in the liquid heating process is achieved through the monitoring of virtually divided subspaces and thermal image acquisition devices, combined with intelligent control of the stirrer. Specifically, the cavity of the heating container is divided into multiple subspaces 2, and a thermal image acquisition device 4 is installed outside the cavity to identify the temperature difference between each subspace 2. A stirrer 5 is configured inside each subspace 2. When the temperature difference between a certain subspace 2 and other subspaces 2 is detected to be greater than a preset temperature difference, the stirring of the liquid in the adjacent subspaces of that subspace 2 is accelerated by the stirring of the stirrer 5, thereby uniformly heating the liquid temperature in the container. With the precise monitoring of the thermal image acquisition device 4 and the targeted stirring of the stirrer 5, the consistency of the liquid temperature in the container is ensured, reducing the time required to reach a uniform temperature, thus improving heating efficiency and enhancing the user experience. Uniform temperature distribution reduces the risk of material aging due to localized high temperatures, helping to extend the service life of the heating element and the entire device. Overheating is avoided, reducing unnecessary energy consumption and optimizing energy utilization during the heating process.

[0040] In one possible implementation, for each edge subspace in the plurality of subspaces 2, the stirrer 5 within the edge subspace is configured to operate when the edge subspace is the target subspace indicated by the thermal image; the number of adjacent subspaces of the edge subspace is less than or equal to the number of adjacent subspaces of any subspace 2 other than the edge subspace. Specifically, the edge subspace refers to the subspace located at the edge of the heating container cavity. Edge subspaces are geometrically isolated and directly connected to fewer other subspaces. Due to their unique location, they face temperature uniformity issues during heating, unlike the central or internal subspaces 2. When the edge subspace is identified as the target subspace by the thermal image acquisition device 4, i.e., when the temperature of this edge subspace differs significantly from other subspaces 2, in addition to the stirrers 5 within the adjacent subspaces of the edge subspace, the stirrer 5 within the edge subspace also performs stirring to promote liquid mixing, thereby reducing temperature differences and achieving a more uniform temperature distribution.

[0041] Specifically, in this embodiment, stirrers 5 are configured in each subspace 2, and the working state of the stirrers 5 is controlled based on feedback from the thermal image acquisition device 4. When the temperature difference between the edge subspace and other subspaces is greater than a preset temperature difference, since the number of adjacent subspaces of the edge subspace is small, the stirrers 5 in the edge subspace and its adjacent subspaces work simultaneously, which can effectively improve the temperature uniformity of the edge subspace and avoid local overheating or undercooling. Uniform temperature distribution helps to improve heating efficiency, achieve a more efficient and uniform heating process, reduce energy waste, and extend the service life of the equipment.

[0042] In one possible implementation, multiple stirrers 5 are used to operate when the number of target subspaces indicated by the thermal image exceeds a preset number. Specifically, the operating state of the stirrers 5 is related not only to the target subspaces indicated by the thermal image acquisition device 4, but also to the number of target subspaces indicated by the thermal image acquisition device 4. A target subspace refers to a subspace 2 identified by the thermal image acquisition device 4 whose temperature difference from other subspaces 2 is greater than a preset temperature difference. The preset number is a threshold used to determine when the stirrers 5 in the cavity need to operate simultaneously to adjust the uniformity of the liquid temperature. Specifically, when the number of target subspaces detected by the thermal image acquisition device 4 exceeds the preset number, indicating a large non-uniformity of temperature distribution in the cavity, multiple stirrers 5 need to operate simultaneously to accelerate liquid mixing in order to achieve faster temperature equilibrium. Therefore, all the stirrers 5 in the cavity will be activated and enter the operating state.

[0043] Specifically, in this embodiment, when the temperature distribution within the cavity is highly uneven, multiple stirrers 5 within the cavity are activated to work collaboratively, rapidly responding to the uneven temperature distribution, accelerating liquid mixing, and reducing the time required to reach a uniform temperature. The simultaneous operation of multiple stirrers helps improve heating efficiency, achieving a more efficient and uniform heating process, enhancing user experience and equipment performance, especially when the heating container is large or the heating demand is high.

[0044] In one possible implementation, the stirrer 5 includes a drive motor 6, a stirring rod 7, and impellers 8. Multiple impellers 8 are distributed along the axial direction of the stirring rod 7 and are positioned on it. The drive end of the drive motor 6 is connected to one end of the stirring rod 7 to drive the stirring rod 7 to rotate, thereby causing the stirring rod 7 to drive the impellers 8 to rotate around the stirring rod 7. Specifically, the drive motor 6 is the core power source of the stirrer 5, responsible for driving the stirring motion. The selection of the drive motor 6 needs to consider its power, torque, and durability to adapt to different stirring requirements and working environments. The stirring rod 7 is the intermediary component connecting the drive motor 6 and the impellers 8; its design needs to ensure sufficient strength and rigidity to withstand the torque during the stirring process and possible chemical or physical corrosion. The impellers 8 are the components that generate the stirring action; their shape, size, and number directly affect the stirring efficiency and liquid flow pattern. The impellers 8 are distributed along the axial direction of the stirring rod 7; this arrangement helps to achieve a wider range of liquid mixing and improves stirring efficiency. When the stirrer 5 is working, the drive motor 6 drives the stirring rod 7 to rotate, and the impellers 8 rotate accordingly, thereby agitating the liquid in the chamber and achieving liquid flow and mixing. In practice, the number of blades 8 needs to be appropriate. Too few blades will result in insufficient mixing, while too many blades will exceed the load capacity of the drive motor 6, leading to stalling or reduced motor life.

[0045] In practice, the shape, size, and material of the impeller 8 are optimized according to the properties of the liquid to be heated within the cavity to ensure optimal stirring performance. The drive motor 6 needs sufficient power and torque to drive the stirring rod 7 and the impeller 8, especially during high-speed stirring. The operating status of the stirrer 5 is coordinated with the control system of the heating container to achieve temperature feedback-based control.

[0046] Specifically, in this embodiment, by setting up a drive motor 6, a stirring rod 7, and a paddle 8, the stirring efficiency is improved. Under the guidance of the thermal image acquisition device 4, the liquid in the cavity can be made to reach a uniform temperature in a short time, thereby improving heating efficiency, reducing energy waste, achieving a more efficient and uniform heating process, and enhancing user experience and equipment performance.

[0047] In one possible implementation, multiple blades 8 on the stirring rod 7 are arranged in a staggered pattern. Specifically, the staggered arrangement of the blades 8 can more effectively break up the flow layer in the liquid, promote rapid mixing between different areas of the liquid, and thus accelerate temperature equalization. The staggered blades can stir the liquid at different levels, increasing the turbulence of the liquid and improving stirring efficiency. In a specific implementation, along the axial direction of the stirring rod 7, two adjacent blades 8 are in a complementary position, so that one blade fills the gap left by the other blade during stirring, ensuring that there are no dead zones in the liquid flow during the entire stirring process, thereby transferring heat from one area to another more quickly and accelerating the temperature mixing of the liquid in the cavity.

[0048] Specifically, in this embodiment, the staggered arrangement of the blades 8 reduces the time required to reach a uniform temperature, thereby improving heating efficiency. Faster temperature mixing helps reach the desired temperature more quickly, thus reducing energy waste. Effective liquid mixing reduces the impact of high-speed flowing liquid on the inner wall of the container shell 1, thereby reducing wear of the agitator 5 on the inner wall of the cavity container shell 1.

[0049] In one possible implementation, multiple sub-spaces 2 are distributed along a first direction perpendicular to the axial direction of the stirring rod 7. Specifically, distributing the sub-spaces 2 along the first direction perpendicular to the axial direction of the stirring rod 7 ensures that the liquid flow path of the stirrer 5 can cover more sub-spaces 2 during operation, and its blades 8 can influence more sub-spaces 2, resulting in better mixing of the liquids in different sub-spaces 2 during stirring, thereby improving stirring efficiency and contributing to a more uniform temperature distribution. The distribution of sub-spaces perpendicular to the stirring rod 7 can increase turbulence during liquid flow. Turbulence can more effectively mix the liquid and reduce temperature gradients, helping to improve heat transfer efficiency. It also helps to reduce dead zones in the cavity, ensuring that the liquid in all sub-spaces 2 is adequately stirred and heated.

[0050] Specifically, in this embodiment, the subspace distribution perpendicular to the stirring rod 7 ensures that when the stirrer 5 is working, its blades 8 can affect more subspaces 2, which helps to achieve more efficient heat transfer and more uniform temperature distribution, thereby improving heating efficiency.

[0051] In one possible implementation, for each of the plurality of subspaces 2, the stirrer 5 within subspace 2 and the stirrers 5 in adjacent subspaces are arranged opposite each other along the axial direction of the stirring rod 7 on the inner wall of the container shell 1. Specifically, each subspace 2 is equipped with a corresponding stirrer 5, which are arranged opposite each other along the axial direction of the stirring rod 7 on the inner wall of the container shell 1 to ensure effective stirring in each subspace 2, thereby achieving uniform mixing and temperature control of the liquid. The axial arrangement of the stirrers 5 facilitates the circulation of the liquid within the subspace 2, which is crucial for maintaining the uniformity of the liquid temperature. In a specific implementation, the drive motor 6 is fixed to the inner wall of the container shell 1, which helps to reduce space occupation and facilitates the maintenance and replacement of the motor. For example, as shown in the figure... Figure 3 As shown, following the conventional placement of the heating container, the cavity is equipped with four stirrers 5. A first drive motor and a third drive motor are fixedly installed on the inner wall of one side of the container shell 1, and a second drive motor and a fourth drive motor are fixedly installed on the inner wall of the other side of the container shell 1. These two inner walls are arranged opposite to each other.

[0052] Specifically, in this embodiment, the stirrer 5 in subspace 2 and the stirrer in the adjacent subspace are arranged opposite each other along the axial direction of the stirring rod 7. This symmetrical arrangement helps to maintain the balance of the heating container, reduce vibration or tilting caused by the operation of the stirrer 5, and maintain the stability and reliability of the heating container.

[0053] In one possible implementation, the heating container further includes a water inlet pipe 9. One end of the water inlet pipe 9 is connected to a water source, and the other end forms multiple branch pipes 10. These branch pipes 10 are connected to the cavity, allowing the water source to be evenly distributed to multiple sub-spaces 2 within the cavity. Specifically, when the liquid to be heated is water, one end of the water inlet pipe 9 is connected to the water source. The water enters the water inlet pipe 9, passes through the multiple branch pipes 10, and then enters the cavity. The advantage of using multiple branch pipes 10 is that when room temperature water is added to the cavity of the heating container, the water enters the cavity more evenly, reducing the impact on water temperature fluctuations within the cavity. Of course, having as many and evenly distributed branch pipes 10 as possible yields better results. In specific implementations, the end of the water inlet pipe 9 connected to the water source is typically connected to a water purifier. The number of branch pipes 10 can be optimized according to the size and shape of the cavity. For example, five branch pipes 10 can be set, and adjustments can be made as needed in practical applications. According to the conventional placement of the heating container, a water level probe 12 is installed on the top of the container shell 1 inside the cavity. The water level probe 12 is used to monitor the water level inside the cavity and control the opening of the water inlet valve 11 to keep the water inside the cavity always above the middle water level.

[0054] Specifically, in this embodiment, multiple branch pipes 10 can ensure that room temperature water enters the cavity more evenly, reduce the local drop in water temperature caused by direct water flow impact, and achieve more uniform water replenishment; the evenly distributed water flow can reduce the impact on the water temperature in the cavity during the water replenishment process, and help maintain the stability of the water temperature in the cavity; through uniform water replenishment, local overheating or overcooling can be reduced, thereby improving heating efficiency and energy utilization.

[0055] In one possible implementation, the container shell 1 includes a first side and a second side arranged vertically opposite each other, with the first side being higher than the second side in the vertical direction, and a plurality of branch pipes 10 evenly distributed on the first side. Specifically, in accordance with the conventional placement of a heating container, the first side is the top of the container shell 1, the second side is the bottom of the container shell 2, and the plurality of branch pipes 10 are evenly distributed on the top of the container shell 1.

[0056] Specifically, in this embodiment, multiple branch pipes 10 are evenly distributed on the top of the container shell 1, which helps the liquid to circulate naturally. Because the liquid will flow from high to low due to gravity, it helps to ensure that the liquid can enter the cavity evenly, reduce the impact on the existing water temperature, and thus help maintain the stability of the water temperature in the cavity and reduce excessive impact or heating in local areas.

[0057] In one possible implementation, the first direction is vertical. Accordingly, multiple sub-spaces 2 are distributed vertically, the axis of the stirring rod 7 is horizontal, and the surface formed by the rotation of the impeller 8 around the stirring rod 7 is perpendicular to the horizontal direction. When the impeller 8 rotates, it can effectively push the liquid upward or downward in the vertical direction, enhancing the mixing of the liquid in the vertical direction, that is, enhancing the mixing of the liquid between the various sub-spaces 2 distributed in the vertical direction. Since the heating device 3 is usually located at or near the bottom of the container shell 1, the liquid may form natural convection, in which hotter water rises and colder water sinks. Therefore, vertical heat transfer is crucial for maintaining the temperature uniformity throughout the cavity, and the impeller 8 helps to transfer heat more effectively from the heating area to areas away from the heating source.

[0058] Specifically, in this embodiment, multiple subspaces 2 are distributed vertically, the axis of the stirring rod 7 is horizontal, and the surface formed by the rotation of the blade 8 around the stirring rod 7 is perpendicular to the horizontal direction. When the blade 8 rotates, it can effectively push the liquid upward or downward along the vertical direction, which enhances the mixing of the liquid between the various subspaces 2 distributed along the vertical direction, reduces the temperature gradient, and thus improves the heating efficiency.

[0059] To facilitate understanding of the technical solution of this application, the following will be used as an example. Figure 3-4Taking an example, the working process of the heating container provided in this application embodiment will be described in detail. Specifically, the cavity is divided into four subspaces 2, which are respectively referred to as the first subspace, the second subspace, and the third subspace. Correspondingly, the drive motors 6 of the stirrer 5 in each subspace are respectively referred to as the first drive motor, the second drive motor, the third drive motor, and the fourth drive motor. Among them, the first subspace and the fourth subspace are edge subspaces. The control method of the heating container includes the following steps:

[0060] This diagram is a flowchart of a heating vessel control system, used to describe the control logic of the stirrer during the heating process. The following are the implementation steps summarized from the flowchart:

[0061] (1) The heating container starts heating after the user takes water from the heating container.

[0062] (2) Start the drive motor 6 of the four agitators 5 to promote more even water replenishment.

[0063] (3) Based on the thermal images acquired by the thermal image acquisition device 4, determine the temperature distribution of the four subspaces 2 inside the heating container.

[0064] (4) Temperature difference judgment:

[0065] If the temperature difference between the second subspace and other subspaces is large, start the first drive motor and the third drive motor, run for a period of time (e.g., 2 minutes), and then judge the temperature distribution again.

[0066] If the temperature difference between the third subspace and other subspaces is large, the second and fourth drive motors are started and run for a period of time (e.g., 2 minutes) before the temperature distribution is judged again.

[0067] If the temperature difference between the first subspace and other subspaces is large, start the first drive motor and the second drive motor, run for a period of time (e.g., 2 minutes), and then judge the temperature distribution again.

[0068] If the temperature difference between the fourth subspace and other subspaces is large, the third and fourth drive motors are started and run for a period of time (e.g., 2 minutes) before the temperature distribution is judged again.

[0069] If more than two subspaces have a large temperature difference with other subspaces, start the drive motors 6 of all four stirrers 5 and run them for a period of time (e.g., 2 minutes) before judging the temperature distribution again.

[0070] (5) When the temperatures of the four subspaces are close, the heating and stirring process is considered to have achieved the expected effect.

[0071] (6) Stop the heating process of the heating container when the temperature of the liquid in the cavity reaches the preset target temperature.

[0072] In summary, the heating container of this application has its cavity divided into multiple sub-spaces. A thermal image acquisition device is installed outside the cavity to identify the temperature difference between the sub-spaces. Each sub-space is equipped with a stirrer. When the thermal image acquisition device detects that the temperature difference between a certain sub-space and other sub-spaces is greater than a preset temperature difference, the stirring of the stirrers in the adjacent sub-spaces accelerates the mixing of the liquid in that sub-space with the liquid in its adjacent sub-spaces, thereby uniformly heating the liquid temperature inside the container. Through the precise monitoring of the thermal image acquisition device and the targeted stirring of the stirrers, the consistency of the liquid temperature inside the container is ensured, reducing the time required to reach a uniform temperature, thus improving heating efficiency and enhancing the user experience. Uniform temperature distribution reduces the risk of material aging due to localized high temperatures, helping to extend the service life of the heating element and the entire device. Overheating is avoided, reducing unnecessary energy consumption and optimizing energy utilization during the heating process.
