Description

Technical Field

[0001] The present application relates to the technical field of heating equipment, and in particular to a heating container. Background Art

[0002] In modern home appliance design, in order 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 the uniformity of water temperature. Due to the fixed position of the heating tube, the heating process often leads to obvious differences in water temperature in different areas of the heating tank: the area close to the heating element has a higher water temperature, while the area far from the heating element has a lower temperature. This not only affects the temperature stability of the water when it is discharged, resulting in a poor user experience, such as the phenomenon of temperature fluctuations under continuous water use, but also increases the complexity of product design and optimizing the layout of the water outlet.

[0003] In addition, uneven temperature distribution in the water tank may have more serious consequences. For example, some areas fail to reach the necessary disinfection or sterilization temperature, providing conditions for the growth of bacteria and other microorganisms, which in turn threatens the safety of water quality. At the same time, the phenomenon of overheating in some areas and underheating in others will lead to inefficient energy utilization and may accelerate the aging process of heating elements and shorten their service life. Long-term temperature unevenness will also aggravate the aging of materials inside the water tank due to thermal expansion and contraction, increase the risk of seal failure, water leakage, and the resulting increase in maintenance costs.

[0004] Although the introduction of temperature sensors can monitor temperature changes in the water tank, this method can only provide limited information, cannot achieve comprehensive coverage, and cannot fundamentally solve the problem of uneven heating temperature. Summary of the invention

[0021] The present application provides a heating container, which divides the cavity of the heating container into multiple subspaces, and sets a thermal image acquisition device outside the cavity to identify the temperature difference between the subspaces, and configures a stirrer inside each subspace. When it is detected that the temperature difference between a certain subspace and other subspaces is greater than the preset temperature difference, the stirring of the stirrer in the adjacent subspace of the subspace accelerates the mixing of the liquid in the subspace and the liquid in the adjacent subspace to uniformly heat the temperature of the liquid in the container.

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

[0033] The container shell 1 is enclosed to form a cavity for holding the liquid to be heated; the cavity is divided into a plurality of subspaces 2 that are interconnected. 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 because of its corrosion resistance and high temperature resistance, but its cost is relatively high; aluminum alloy is favored because of its light weight and good thermal conductivity, but its chemical resistance is relatively poor. The wall thickness of the container shell 1 directly affects its strength and pressure resistance. According to the maximum pressure and temperature that may be generated during the liquid heating process, the optimal wall thickness design is determined by finite element analysis to ensure the safety and durability of the container. In order 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 a material with high thermal resistance. For example, using polyurethane foam as an insulation material can effectively reduce heat loss and improve heating efficiency. Specifically, the cavity is virtually divided into a plurality of subspaces 2, which are not physically isolated from each other, but are regarded as independent areas in terms of control logic, so as to perform separate temperature monitoring and management on the liquids in different areas. A water outlet pipe 13 connected to the cavity and a water outlet valve 14 arranged on the water outlet pipe 13 are arranged on the container shell 1. When the user takes water, the water outlet valve 14 will open to discharge water. An exhaust pipe 15 connected to the cavity and an exhaust valve 16 arranged on the exhaust pipe 15 are arranged on the container shell 1. When heated and boiled, the exhaust valve 16 will be opened, and the high-pressure steam inside the cavity will be discharged from the cavity along the exhaust pipe 15 to ensure that the heating container will not have the problem of expansion and leakage. According to the conventional placement of the heating container, the water outlet pipe 13 is arranged close to the bottom of the heating shell 1, and the exhaust pipe 15 is arranged close to the top of the heating shell 1.

[0034] The heating device 3 is arranged inside the cavity and is used to heat the liquid to be heated in the cavity. In a specific implementation, according to the conventional placement of the heating container, the heating device 3 is usually arranged at the bottom of the container 1 in the cavity, and the heating device 3 can be set as a circular heating plate. Specifically, the heating device 3 can adopt 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 according to the capacity and heating requirements of the heating container; specifically, the power of the heating device 3 matches the heating requirements of the container. Excessive power may cause energy waste and overheating, while too little power cannot meet the heating requirements. The required heating power can be determined by calculating the mass, specific heat capacity and target temperature difference of the liquid. 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] Thermal image acquisition device 4, thermal image acquisition device 4 is arranged outside the cavity, and the field of view of thermal image acquisition device 4 covers the cavity; the thermal image acquired by thermal image acquisition device 4 is used to indicate the target subspace among the multiple subspaces 2; the temperature difference between the liquid to be heated in the target subspace and the liquid to be heated in the subspaces 2 other than the target subspace among the multiple subspaces 2 is greater than the preset temperature difference. Specifically, thermal image acquisition device 4 is a key component in 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, which is used to judge the temperature difference between each subspace 2, and the control system can identify the target subspace with a temperature higher or lower than that of other subspaces. Infrared thermal imaging technology is based on the relationship between the infrared radiation emitted by the object and the temperature. It captures the thermal radiation signal through a highly sensitive infrared detector and converts it into a visual thermal image; infrared thermal imaging technology can provide an intuitive image of the temperature field, and has the advantages of non-contact measurement, rapid response and wide coverage. In the heating container, infrared thermal imaging technology can monitor the temperature of each subspace 2 in real time to ensure the uniformity and efficiency of the heating process. In a specific implementation, 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 instantly.

[0036] In the specific implementation, the configuration of the thermal image acquisition device 4 needs to consider its installation position outside the cavity, the field of view angle, and the interface with the control system. According to the conventional placement of the heating container, in order to ensure that the thermal image acquisition device can cover the entire cavity, the thermal image acquisition device 4 is usually installed on the top or side of the cavity to obtain the best field of view angle and the smallest temperature measurement error. 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 angle directly affects the comprehensiveness and accuracy of temperature monitoring. According to the size and shape of the cavity, a suitable thermal image acquisition device 4 is selected to ensure that its field of view angle can meet the monitoring requirements. The thermal image acquisition device 4 needs to be connected to the control system of the heating container to realize real-time transmission and processing of temperature data, which is usually achieved by wired or wireless means to ensure the stability and real-time nature of data transmission. The collected thermal image data needs to be processed by a specific algorithm to extract temperature information and indicate the target subspace; the processing of thermal image data includes steps such as image enhancement, noise filtering, and temperature extraction. Through these processes, the quality of thermal images can be improved, environmental interference can be reduced, and the temperature information of each subspace 2 can be accurately extracted. Then, the temperature difference between each subspace 2 can be identified and indicated. When the temperature difference between a subspace 2 and other subspaces 2 exceeds the preset temperature difference, the subspace 2 is determined as the target subspace, and the system automatically adjusts the working state of the stirring device. In a specific implementation, an image processing system can be set inside the thermal image acquisition device 4 to identify the target subspace and turn on the corresponding stirrer 2 for the target subspace.

[0037] A stirring device, the stirring device includes a plurality of stirrers 5 corresponding to a plurality of subspaces 2, each stirrer 5 being arranged inside the corresponding subspace 2. Specifically, the layout of the stirrer 5 in the subspace needs to take into account the dynamic characteristics of the liquid flow, and the placement position and angle of the stirrer 5 should promote the circulation of the liquid, avoid the formation of dead angles and eddies, so as to ensure the uniformity of the liquid temperature and composition in the entire subspace. In the specific implementation, stirrers of paddle type, turbine type, anchor type and the like can be used, and the specific type of stirrer 5 needs to be selected according to the physical properties of the liquid and the purpose of stirring. For example, a paddle stirrer is suitable for mixing low-viscosity liquids, while an anchor stirrer is suitable for stirring high-viscosity liquids. The material of the stirrer 5 needs to be selected according to the chemical properties of the liquid to ensure corrosion resistance and stability. Commonly used materials include stainless steel, titanium alloy and special plastics. When a subspace is indicated as a target subspace by the thermal image acquisition device, the stirrer in at least one adjacent subspace of the subspace will automatically enter the working state, ensuring the timely mixing of the liquid during the heating process.

[0038] For each subspace 2 among the multiple subspaces 2, the agitator 5 in at least one adjacent subspace of the subspace 2 is used to be in working state when the subspace 2 is the target subspace indicated by the thermal image; the adjacent subspace of the subspace 2 is the subspace 2 adjacent to the subspace 2 among the multiple subspaces 2. Specifically, each subspace 2 is configured with a corresponding agitator 5. When a subspace 2 is identified as a target subspace, the agitator 5 in at least one adjacent subspace of the subspace 2 will be activated and start working. The agitator in the working state stirs the liquid, promotes the mixing of the liquid in the target subspace and the liquid in its adjacent subspace, helps to reduce the temperature difference, and transfers heat from one area to another, thereby achieving a more uniform temperature distribution. The entire system forms a closed-loop control, the thermal image acquisition device provides feedback, the control system makes adjustments, and the agitator performs actions, and the three work together to maintain the temperature uniformity of the liquid in the cavity.

[0039] Specifically, in the embodiment of the present application, the temperature uniformity of the liquid heating process is achieved through the monitoring of the virtual divided subspaces and the thermal image acquisition device, combined with the intelligent control of the stirrer. Specifically, the cavity of the heating container is divided into a plurality of subspaces 2, and a thermal image acquisition device 4 is arranged outside the cavity to identify the temperature difference between each subspace 2. A stirrer 5 is arranged inside each subspace 2. When it is detected that the temperature difference between a certain subspace 2 and other subspaces 2 is greater than the preset temperature difference, the stirring of the stirrer 5 in the adjacent subspace of the subspace 2 accelerates the mixing of the liquid in the subspace 2 and the liquid in the adjacent subspace to uniformly heat the temperature of the liquid in the container. With the help of the precise monitoring of the thermal image acquisition device 4 and the targeted stirring of the stirrer 5, the consistency of the temperature of the liquid in the container is ensured, and the time required to reach a uniform temperature is reduced, thereby improving the heating efficiency and enhancing the user experience; the uniform temperature distribution reduces the risk of material aging caused by local high temperature, which helps to extend the service life of the heating element and the entire device; overheating is avoided, unnecessary energy consumption is reduced, and the energy utilization rate during the heating process is optimized.

[0040] In one possible embodiment, for each edge subspace among the multiple subspaces 2, the stirrer 5 in the edge subspace is used to be in working state 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 among the multiple subspaces 2. Specifically, the edge subspace refers to the subspace located at the edge position in the cavity of the heating container. The edge subspace is relatively isolated in geometric layout and is directly connected to fewer other subspaces. Due to the particularity of its position, it faces a temperature uniformity problem different from that of the central or internal subspace 2 during the heating process. When the edge subspace is identified as a target subspace by the thermal image acquisition device 4, that is, when the temperature of the edge subspace is greatly different from that of other subspaces 2, in addition to the stirrer 5 in the adjacent subspace of the edge subspace performing stirring work, the stirrer 5 configured in the edge subspace also performs stirring work to promote the mixing of the liquid, thereby reducing the temperature difference and achieving a more uniform temperature distribution.

[0041] Specifically, in the embodiment of the present application, by configuring a stirrer 5 in each subspace 2 and controlling the working state of the stirrer 5 according to the feedback of the thermal image acquisition device 4, when the temperature difference between the edge subspace and other subspaces is greater than the 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 perform stirring work at the same time, which can effectively improve the temperature uniformity of the edge subspace and avoid local overheating or overcooling. 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 embodiment, a plurality of agitators 5 are used to be in a working state when the number of target subspaces indicated by the thermal image is greater than a preset number. Specifically, the working state of the agitator 5 is related not only to the target subspace indicated by the thermal image acquisition device 4, but also to the number of target subspaces indicated by the thermal image acquisition device 4. The target subspace refers to a subspace 2 identified by the thermal image acquisition device 4 as having a temperature difference with other subspaces 2 greater than a preset temperature difference. The preset number is a threshold value used to determine when the agitators 5 in the cavity need to work 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, when the non-uniformity of the temperature distribution in the cavity is large, a plurality of agitators 5 need to work simultaneously to accelerate the mixing of the liquid in order to achieve faster temperature balance, so the agitators 5 in the cavity will be activated and enter the working state.

[0043] Specifically, in the embodiment of the present application, when the temperature distribution in the cavity is relatively uneven, multiple agitators 5 in the cavity are activated to work together to quickly respond to the uneven temperature distribution, speed up the mixing of the liquid, and reduce the time required to reach a uniform temperature. The simultaneous operation of multiple agitators helps to improve the heating efficiency, achieve a more efficient and uniform heating process, and enhance the user experience and equipment performance, especially when the heating container is large or the heating demand is high.

[0044] In one possible embodiment, the agitator 5 includes a drive motor 6, a stirring rod 7 and a paddle 8; a plurality of paddles 8 are distributed along the axial direction of the stirring rod 7 and are arranged on the stirring rod 7; the drive end of the drive motor 6 is connected to one end of the stirring rod 7, and is used to drive the stirring rod 7 to rotate, so that the stirring rod 7 drives the paddle 8 to rotate around the stirring rod 7. Specifically, the drive motor 6 is the core power source of the agitator 5 and is 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 an intermediate component connecting the drive motor 6 and the paddle 8, and its design needs to ensure sufficient strength and rigidity to withstand the torque during the stirring process and possible chemical or physical corrosion. The paddle 8 is a component that produces a stirring effect, and its shape, size and number directly affect the stirring efficiency and liquid flow pattern. The paddle 8 is distributed along the axial direction of the stirring rod 7, and this layout helps to achieve a wider range of liquid mixing and improve the stirring efficiency. When the agitator 5 is working, the rotation of the stirring rod 7 is driven by the drive motor 6, and the paddle 8 rotates accordingly, thereby stirring the liquid in the cavity to achieve the flow and mixing of the liquid. In a specific implementation, the number of the paddles 8 needs to be appropriate, neither too few to result in insufficient stirring, nor too many to exceed the load capacity of the drive motor 6, resulting in stalling or reducing the life of the motor.

[0045] In a specific implementation, the shape, size and material of the paddle 8 are optimized according to the properties of the liquid to be heated in the cavity to ensure the best stirring effect. The drive motor 6 needs to have sufficient power and torque to drive the stirring rod 7 and the paddle 8, especially during high-speed stirring. The working state of the agitator 5 is coordinated with the control system of the heating container to achieve control based on temperature feedback.

[0046] Specifically, in the embodiment of the present application, a driving motor 6, a stirring rod 7 and a paddle 8 are provided to improve the stirring efficiency, and work under the guidance of the thermal image acquisition device 4 to ensure that the liquid in the cavity can reach a uniform temperature in a shorter time, thereby improving the heating efficiency, reducing energy waste, achieving a more efficient and uniform heating process, and improving the user experience and equipment performance.

[0047] In one possible embodiment, the multiple paddles 8 on the stirring rod 7 are staggered. Specifically, the staggered design of the paddles 8 can more effectively break the flow layer in the liquid and promote rapid mixing between liquids in different regions, thereby accelerating temperature equalization. The staggered paddles can stir the liquid at different levels, increase the turbulence of the liquid, and improve the stirring efficiency. In a specific implementation, along the axial direction of the stirring rod 7, two adjacent paddles 8 are in complementary positions, so that one paddle fills the gap left by the other paddle during stirring, ensuring that there are no dead corners for 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 the embodiment of the present application, the staggered arrangement of the blades 8 can reduce the time required to reach a uniform temperature, thereby improving the heating efficiency. Faster temperature mixing helps to reach the required temperature faster, thereby reducing energy waste. Effective liquid mixing can reduce the impact of high-speed flowing liquid on the inner wall of the container shell 1, thereby reducing the wear of the agitator 5 on the inner wall of the cavity container shell 1.

[0049] In one possible embodiment, a plurality of subspaces 2 are distributed along a first direction, and the first direction is perpendicular to the axial direction of the stirring rod 7. Specifically, distributing the subspaces 2 along the first direction perpendicular to the axial direction of the stirring rod 7 can ensure that the path of liquid flow of the stirrer 5 can cover more subspaces 2 when it is working, and its blades 8 can affect more subspaces 2, so that the liquids in different subspaces 2 can be better mixed during the stirring process, thereby improving the stirring efficiency and helping to achieve a more uniform temperature distribution. The distribution of subspaces perpendicular to the stirring rod 7 can increase the turbulence of the liquid during flow, and the turbulence can more effectively mix the liquid and reduce the temperature gradient, which helps to improve the heat transfer efficiency. It also helps to reduce the flow dead angle in the cavity and ensure that the liquid in all subspaces 2 can be fully stirred and heated.

[0050] Specifically, in the embodiment of the present application, the subspace distribution perpendicular to the stirring rod 7 can ensure 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 embodiment, for each subspace 2 among the multiple subspaces 2, the agitator 5 in the subspace 2 and the agitator 5 in the adjacent subspace of the subspace 2 are arranged on the inner wall of the container shell 1 along the axial direction of the stirring rod 7. Specifically, each subspace 2 is configured with a corresponding agitator 5, and these agitators 5 are arranged on the inner wall of the container shell 1 along the axial direction of the stirring rod 7 to ensure that each subspace 2 can be effectively stirred, thereby achieving uniform mixing and temperature control of the liquid. The axial layout of the agitator 5 helps to achieve the circulation of the liquid in the subspace 2, which is crucial to 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 occupancy and facilitates maintenance and replacement of the motor. For example, Figure 3 As shown, according to the conventional placement of the heating container, the cavity is provided with four agitators 5, the first drive motor and the third drive motor are fixedly provided on the inner wall on one side of the container shell 1, and the second drive motor and the fourth drive motor are fixedly provided on the inner wall on the other side of the container shell 1, and the inner walls on both sides are arranged opposite to each other.

[0052] Specifically, in the embodiment of the present application, the agitator 5 in the subspace 2 is arranged relative to the agitator in the adjacent subspace along the axial direction of the stirring rod 7. This symmetrical layout helps to maintain the balance of the heating container, reduce the vibration or tilt caused by the operation of the agitator 5, and maintain the stability and reliability of the heating container.

[0053] In one possible embodiment, the heating container further includes a water inlet pipeline 9, one end of which is used to connect to a water source, and the other end of which forms a plurality of branch pipelines 10, which are respectively connected to the cavity, so that the water source is evenly distributed to the plurality of subspaces 2 of the cavity. Specifically, when the liquid to be heated is water, one end of the water inlet pipeline 9 is used to connect to a water source, and the water source enters the water inlet pipeline 9 and enters the cavity through a plurality of branch pipelines 10. The advantage of using a plurality of branch pipelines 10 here is that when normal temperature water is added to the cavity of the heating container, the normal temperature water will enter the cavity more evenly, which can reduce the influence on the water temperature fluctuation in the cavity. Of course, the branch pipelines 10 here are as many and even as possible to obtain better results. In a specific implementation, one end of the water inlet pipeline 9 used to connect to the water source is usually connected to a water purifier. The number of branch pipelines 10 can be optimized according to the size and shape of the cavity. For example, the branch pipelines 10 can be set to 5, which can be adjusted as needed in actual applications. According to the conventional placement of the heating container, a water level probe 12 is provided on the top of the container shell 1 in the cavity. The water level probe 12 is used to monitor the water level in the cavity and control the opening of the water inlet valve 11 to keep the water in the cavity always above the middle water level.

[0054] Specifically, in the embodiment of the present application, multiple branch pipes 10 can ensure that water at normal temperature enters the cavity more evenly, reduce the local drop in water temperature caused by direct impact of water flow, and achieve more uniform water replenishment; the evenly distributed water flow can reduce the impact of 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 a possible embodiment, the container shell 1 includes a first side and a second side that are arranged opposite to each other in the vertical direction, the first side is higher than the second side in the vertical direction, and a plurality of branch pipes 10 are evenly distributed on the first side. Specifically, according to the conventional placement of the 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 a plurality of branch pipes 10 are evenly distributed on the top of the container shell 1.

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

[0057] In one possible embodiment, the first direction is a vertical direction. Accordingly, a plurality of subspaces 2 are distributed in the vertical direction, the axial direction of the stirring rod 7 is in the horizontal direction, and the surface formed by the rotation of the paddle 8 around the stirring rod 7 is perpendicular to the horizontal direction. When the paddle 8 rotates, it can effectively push the liquid upward or downward in the vertical direction, thereby enhancing the mixing of the liquid in the vertical direction, that is, enhancing the mixing of the liquid between the subspaces 2 distributed in the vertical direction. Since the heating device 3 is usually arranged at the bottom of the container shell 1 or distributed near the bottom, the liquid may form natural convection, in which the hotter water rises and the colder water falls, so the heat transfer in the vertical direction is essential to maintain the uniformity of the temperature in the entire cavity, and the paddle 8 helps to transfer the heat from the heating area to the area away from the heating source more efficiently.

[0058] Specifically, in the embodiment of the present application, multiple subspaces 2 are distributed in the vertical direction, the axial direction of the stirring rod 7 is in the horizontal direction, and the surface formed by the rotation of the paddle 8 around the stirring rod 7 is perpendicular to the horizontal direction. When the paddle 8 rotates, the liquid can be effectively pushed upward or downward in the vertical direction, thereby enhancing the mixing of the liquid between the subspaces 2 distributed in the vertical direction, reducing the temperature gradient, and thus improving the heating efficiency.

[0059] In order to facilitate understanding of the technical solution of this application, Figure 3-4As an example, the working process of the heating container provided in the embodiment of the present application is described in detail. Specifically, the cavity is divided into four subspaces 2, which are respectively recorded as the first subspace, the second subspace, and the third subspace. Correspondingly, the driving motors 6 of the stirrers 5 in each subspace are respectively recorded as the first driving motor, the second driving motor, the third driving motor, and the fourth driving 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 figure is a flow chart of the heating container control system, which is used to describe the control logic of the agitator during the heating process. The following are the implementation steps organized according to the flow chart:

[0061] (1) When the user takes water from the heating container, the heating container starts heating.

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

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

[0064] (4) Temperature difference judgment:

[0065] If the temperature difference between the second subspace and the other subspaces is large, the first drive motor and the third drive motor are started, and the temperature distribution is determined again after running for a period of time (such as 2 minutes);

[0066] If the temperature difference between the third subspace and the other subspaces is large, the second drive motor and the fourth drive motor are started, and the temperature distribution is determined again after running for a period of time (such as 2 minutes);

[0067] If the temperature difference between the first subspace and the other subspaces is large, the first drive motor and the second drive motor are started, and the temperature distribution is determined again after running for a period of time (such as 2 minutes);

[0068] If the temperature difference between the fourth subspace and the other subspaces is large, the third drive motor and the fourth drive motor are started, and the temperature distribution is determined again after running for a period of time (such as 2 minutes);

[0069] If the temperature difference between more than two subspaces and the other subspaces is large, the drive motors 6 of all four agitators 5 are started and the temperature distribution is determined again after running for a period of time (such as 2 minutes).

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

[0071] (6) When the temperature of the liquid in the cavity reaches a preset target temperature, the heating process of the heating container is stopped.

[0072] In summary, the cavity of the heating container of the present application is divided into multiple subspaces, and a thermal image acquisition device is arranged outside the cavity. The thermal image acquisition device is used to identify the temperature difference between each subspace, and a stirrer is arranged inside each subspace. When the thermal image acquisition device detects that the temperature difference between a certain subspace and other subspaces is greater than the preset temperature difference, the stirring of the stirrer in the adjacent subspace of the subspace accelerates the mixing of the liquid in the subspace and the liquid in the adjacent subspace to uniformly heat the temperature of the liquid in the container. With the help of the precise monitoring of the thermal image acquisition device and the targeted stirring of the stirrer, the consistency of the temperature of the liquid in the container is ensured, and the time required to reach a uniform temperature is reduced, thereby improving the heating efficiency and enhancing the user experience; the uniform temperature distribution reduces the risk of material aging caused by local high temperature, which helps to extend the service life of the heating element and the entire equipment; overheating is avoided, unnecessary energy consumption is reduced, and the energy utilization rate during the heating process is optimized.
