It should be understood by those skilled in the art that the present disclosure can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present disclosure.

[0032] Figures 1 to 3 A schematic diagram of the structure of a cooking appliance, a schematic diagram of the structure of a heat exchange assembly, and a schematic diagram of the front view of the cooking appliance are respectively shown in FIG. Figures 1 to 3 As shown, the above cooking appliance comprises:

[0033] The cooking liner is a container part inside the cooking utensil for holding food and receiving heating. It is in direct contact with the food and cooks food by heating. The cooking utensil can be a steam oven, an electric pressure cooker, and other cooking utensil with a preset cooking function. A heat exchange component 12 is provided on the outer side of the top of the cooking liner. The heat exchange component 12 has good thermal conductivity. The heat exchange component 12 is in close contact with the outer side of the top of the cooking liner to take away the heat in the cooking liner and does not directly occupy the area of ​​the cooking space, thereby providing more cooking space for food.

[0034] The heat exchange assembly 12 includes an inlet pipe 121, a heat exchange pipeline 122 and an outlet pipe 123 connected in sequence, and the inlet pipe 121 and the outlet pipe 123 are connected to the adapter module 11. Specifically, the adapter module 11 is arranged at one end of the cooking utensil near the top, which can reduce the length of the inlet pipe 121 and the outlet pipe 123, and increase the space utilization and heat exchange efficiency. In the embodiment of the present disclosure, the heat exchange pipeline 122 is designed as a serpentine pipeline, and the heat exchange pipeline 122 is made of aluminum. In the heat exchange pipeline 122, the coolant flows through a series of curved pipes, and the outer surfaces of these pipes are in contact with the surface of the cooking pot. Since aluminum has good thermal conductivity, it can efficiently transfer the coldness of the coolant to the cooking pot, and it is lightweight, corrosion-resistant and low in cost. The curved shape of the serpentine pipeline helps to increase the heat exchange area and improve the heat exchange efficiency. Compared with traditional straight pipes, serpentine pipes can better cover a larger area and ensure uniform cooling of the cooking pot. It is understandable that commonly used materials with good thermal conductivity include copper, brass, stainless steel and various alloys. Common designs of the heat exchange pipeline 122 also include spiral, S-shaped, Z-shaped, etc. In other embodiments, the heat exchange pipeline 122 can be designed according to the specific equipment structure and functional requirements by selecting suitable materials, so as to achieve the best heat exchange effect and equipment performance. The embodiments of the present disclosure are not limited to this. The water inlet pipe 121 and the water outlet pipe 123 are both insulated water pipes, which can effectively isolate and control the cold amount, so that the coolant they transport will not directly contact the surrounding environment, which can effectively reduce the loss of cold amount and improve energy efficiency. The heat exchange pipeline 122 has pipe interfaces at both ends. The water inlet pipe 121 and the water outlet pipe 123 are installed to the pipe interfaces of the heat exchange pipeline 122 through connectors such as joints and valves to achieve connection. It should be noted that the connector should match the diameter of the heat exchange pipeline 122.

[0035] A refrigeration component 2, which is external to the cooking utensil, and is used to provide the coolant to the heat exchange component 12. Common refrigeration components 2 include centrifugal chillers, screw chillers, piston chillers, etc. Placing the refrigeration component 2 outside the cooking utensil reduces the occupation of the cooking space in the cooking liner, and the user can freely adjust the refrigeration component 2 according to actual needs, thereby improving the flexibility of use and refrigeration efficiency and facilitating cleaning and maintenance by the user. In addition, the external refrigeration component 2 can be used by multiple cooking utensils, thereby reducing the cost of use. The refrigeration component 2 includes a liquid inlet pipe and a liquid return pipe, and the liquid inlet pipe and the liquid return pipe are connected to the adapter module 11, so that the refrigeration component 2 and the heat exchange component 12 are connected through the adapter module 11 to form a coolant circulation pipeline. Specifically, the refrigeration unit outputs the coolant to the heat exchange component 12 through the liquid outlet pipe, and the coolant exchanges heat with the cooking pot in the heat exchange pipeline 122, taking away the heat of the cooking pot, thereby achieving refrigeration, and the coolant after heat exchange returns to the refrigeration component 2 through the outlet pipe 123, forming a closed cycle. In some embodiments, the adapter module 11 may include multiple joints, valves, and possible measuring instruments to ensure that the coolant flows correctly in the pipeline and allow maintenance personnel to monitor and operate the system.

[0036] In the embodiment of the present disclosure, the refrigeration component 2 is arranged outside the cooking utensil, and the heat exchange component 12 is arranged inside the cooking utensil, and they are connected through the adapter module 11 on the cooking utensil to form a coolant circulation, so that the refrigeration component 2 delivers the coolant to the heat exchange component 12, and recovers the coolant after heat exchange. The use of a separate design can prevent the stability and safety of the refrigeration system from being affected by the excessively high temperature inside the cooking utensil, reduce safety hazards caused by refrigerant leakage or other failures, and make maintenance or replacement more convenient, which also helps to extend the overall service life of the cooking utensil and the refrigeration system. When designing the cooking utensil according to the embodiment of the present disclosure, there is no need to consider the complex refrigeration system, and the focus can be on the design of the cooking liner and the adapter module 11, which simplifies the design and manufacturing process of the entire product, thereby further reducing costs.

[0037] Based on the above disclosed embodiment, the cooking utensil further includes a control component, a first temperature sensor is provided in the cooking liner, a second temperature sensor is provided on the heat exchange component 12, the first temperature sensor is used to detect the temperature in the cooking liner, the second temperature sensor is used to detect the temperature of the heat exchange pipeline 122, and the control component is used to control the refrigeration component 2 according to the temperature of the cooking liner and the heat exchange pipeline 122. Specifically, by monitoring the temperature of the cooking liner, the refrigeration capacity can be adjusted according to actual needs, unnecessary energy waste can be avoided, a higher energy efficiency ratio can be achieved, and the user experience can be improved. The temperature of the heat exchange pipeline 122 is monitored in real time by the second sensor, which helps to prevent the freezing phenomenon caused by the excessively low temperature of the coolant, resulting in the blockage of the heat exchange pipeline 122, thereby affecting the normal operation and life of the equipment. Therefore, the application of the temperature sensor in the cooking utensil in the disclosed embodiment not only improves the quality and convenience of cooking, but also plays a positive role in energy saving and emission reduction, extending the service life of the equipment, and ensuring food safety. Common types of temperature sensors include thermal resistor sensors, thermal capacitor sensors, infrared sensors, semiconductor sensors, and quartz crystal microbalance sensors, etc., which can be selected according to actual design requirements.

[0038] The adapter module 11 includes a communication interface, a water inlet pipe interface and a water outlet pipe interface. The refrigeration component 2 and the cooking utensil are connected to each other through the communication interface. The communication interface is a technical means that allows data transmission between different devices. The communication interface can be a hardware interface or a software interface, which is used to specify the physical form of the connection between communication devices, electrical signals and other specifications, as well as communication protocols, data formats and other information. Common communication interface types include USB interface, Ethernet interface, wireless interface and serial interface, etc. In practical applications, the selection of the communication interface depends on the specific device type, communication requirements, etc. Therefore, the refrigeration unit in the embodiment of the present disclosure can be connected to the cooking utensil in a wired or wireless manner. The water inlet pipe interface connects the water inlet pipe 121 and the liquid outlet pipe, and the water outlet pipe interface connects the water outlet pipe 123 and the liquid return pipe to form the coolant circulation pipeline. The connection between the refrigeration component 2 and the heat exchange component 12 is realized through the water inlet pipe interface and the water outlet pipe interface, thereby realizing a separate design, which is helpful for designers and maintenance designers to adjust the capacity of the refrigeration component 2 or the heat exchange component 12 according to actual needs, or add more components as needed, providing better flexibility and scalability, and reducing maintenance and repair costs. In addition, the external refrigeration component 2 can be shared by multiple cooking utensils, and the cost of each cooking utensil will be shared, which is lower than equipping each cooking utensil with a built-in water cooling system.

[0039] The refrigeration component 2 includes a compressor, a condenser, an evaporator and a circulating water pump that are interconnected. The outlet end of the circulating water pump is connected to the liquid outlet pipe, the inlet end of the compressor is connected to the liquid return pipe, and the water pump is used to drive the coolant to circulate. Since the refrigeration component 2 is external to the cooking utensil, the problem of compressor overheating caused by insufficient heat dissipation can be avoided, so a high-power compressor can be used for refrigeration, and the use of a high-power compressor can improve the refrigeration efficiency, enhance the adaptability of the equipment, extend the service life of the equipment, and contribute to environmental protection. Commonly used types of circulating water pumps include split-type double-suction centrifugal pumps, single-stage centrifugal pumps, multi-stage centrifugal pumps, vertical long-axis pumps, etc. Using the circulating water pump can not only improve the refrigeration efficiency, enhance the adaptability of the equipment, and extend the service life of the equipment, but also save energy, protect the environment, and facilitate maintenance and management.

[0040] The heat exchange assembly 12 also includes a heat exchange plate 124, which is fitted with the cooking liner, and the heat exchange pipe 122 is installed on the heat exchange plate 124 by welding. The heat exchange plate 124 can be made of a material with good thermal conductivity such as aluminum or steel. The heat exchange plate 124 can increase the heat exchange area, so that more heat is exchanged per unit time, and the overall heat exchange efficiency is improved. In addition, by installing the heat exchange pipe 122 on the heat exchange plate 124 by welding, it can ensure that the heat exchange pipe 122 is firmly connected to the heat exchange plate 124, reduce the risk of leakage, and facilitate maintenance and replacement.

[0041] The heat exchange component 12 is installed on the side wall or top of the cooking pot, and the installation position of the heat exchange component 12 is not lower than a preset height. The preset height in the disclosed embodiment is the highest position where the steaming plate / baking plate can be placed. By setting the heat exchange component 12 at a position not lower than the preset height, the natural convection law of hot air rising and cold air sinking is utilized, thereby improving the heat exchange efficiency. Specifically, the hot gas in the cooking pot will rise due to its low density, and the heat exchange component 12 is set at a higher position to absorb these high-temperature gases faster and take them away through the coolant, thereby reducing the temperature of the cooking pot and improving the heat exchange efficiency.

[0042] The cooking utensil also includes an outer shell and an insulating layer, wherein the insulating layer is located between the cooking liner and the outer shell, and the thickness of the insulating layer is between 12 mm and 20 mm. By providing the insulating layer, heat loss can be reduced, energy efficiency can be improved, and the user can be protected from burns. The insulating layer can be made of a variety of materials, such as ceramics, insulating materials, and the like. For example, in the embodiment of the present disclosure, insulating cotton is used to make the insulating layer. In addition, the insulating layer can also be a specially designed composite material, which has low thermal conductivity and high strength, and can provide effective thermal insulation protection without affecting the performance of the device.

[0043] The total area of ​​the heat exchange pipeline 122 accounts for 10% to 100% of the top area of ​​the cooking pot. In practical applications, the total area of ​​the heat exchange pipeline 122 should be determined according to specific cooking requirements and equipment characteristics to ensure the best cooling effect and equipment performance. It should be noted that, considering the cost issue, the heat exchange pipeline 122 is usually not spread all over the top outer side of the cooking pot.

[0044] The diameter of the heat exchange pipe 122 is between 3 mm and 15 mm, which can meet the requirements of heat exchange efficiency and equipment performance under different cooking conditions.

[0045] The utility model also provides an integrated stove, which comprises the above-mentioned cooking utensil.

[0046] The embodiments of the present disclosure have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
