However, the current heating efficiency of pipeline heating does not meet expectations.

[0044] The embodiments of the present application will be further described in details with reference to the drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

In addition, the person skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples without contradiction.

[0049] It should be noted that the liquid heating assembly of the present application can be applied to a hot water drinking pipeline, and can also be applied to other pipelines using hot water.

[0050] It should be noted that the heating efficiency of the existing pipeline heating has not reached the expected value. One of the key problems is that there is a gap between the target pipeline and the heat conduction sleeve. Due to the filling of air or other non-heat-conducting media in the gap, the efficiency of heat transfer from the heating pipe to the target pipeline is greatly reduced, which in turn affects the ability of the target pipeline to release heat to the surrounding water. This not only leads to unnecessary waste of energy, but also may affect the normal operation of the equipment and the user experience due to insufficient heating.

[0051] In actual production, in order to ensure the stability of the connection between the heat conduction sleeve 200 and the target pipeline 100, the existing liquid heating assembly often adopts the method of stamping a wider welding surface on the heat conduction sleeve 200. However, this method, although to some extent, enhances the welding strength, but also brings the side effects that cannot be ignored. Specifically, the strong force generated in the stamping process often causes the target pipeline 100 inside to deform, and then form a larger gap between the heat conduction sleeve 200 and the target pipeline 100. For details, please refer to Figure 1 and Figure 2 The gap affects the heat transfer of the heating element 400 to the target pipeline 100, and then affects the heat transfer of the target pipeline 100 to the liquid (hereinafter referred to as water) therein. Furthermore, after the target pipeline 100 is deformed, it will increase the accumulation of scale during the heating process, affect the heat transfer, and shorten the service life of the heating element 400.

[0052] To solve the above problems, the liquid heating assembly provided by the utility model effectively solves the gap problem between the heat conduction sleeve 200 and the target pipeline 100 by introducing the first groove 310 of the heat conduction connecting piece 300, and reduces the deformation risk of the target pipeline 100. Specifically, the design of the first groove 310 not only increases the welding area and reduces the welding difficulty, but also reduces the mechanical stress on the target pipeline 100 in the welding process by optimizing the welding process, thereby avoiding unnecessary deformation, improving the stability and reliability of welding, ensuring the smoothness of the heat transfer path, and improving the overall heat transfer efficiency.

[0053] The liquid heating assembly and the liquid heating container of the present application will be described below. Figures 3 to 8 The liquid heating assembly and the liquid heating container of the present application will be described below.

[0054] According to the liquid heating assembly provided by the first aspect of the present application, please refer to Figures 3 to 5 The liquid heating assembly comprises a target pipeline 100, a heat conduction sleeve 200, a heat conduction connecting piece 300 and a heating element 400, the heat conduction sleeve 200 is sleeved on the outer surface of part of the target pipeline 100; the first side of the heat conduction connecting piece 300 is provided with a first groove 310, and the heat conduction sleeve 200 is connected to the first groove 310; and the heating element 400 is arranged on the second side of the heat conduction connecting piece 300.

[0055] According to the liquid heating assembly provided by the present application, the first groove 310 increases the contact area of the heat conduction sleeve 200, thereby reducing the welding difficulty, the heat conduction sleeve 200 can be welded to the heat conduction connecting piece 300 through the first groove 310, the possibility of deformation of the target pipeline 100 is reduced, the possibility of gap between the heat conduction sleeve 200 and the target pipeline 100 is reduced, the filling of air or other non-heat-conducting medium in the gap is avoided, the efficiency of heat transfer from the heating pipe to the target pipeline is greatly improved, and the ability of the target pipeline to release heat to the surrounding water is improved, unnecessary waste of energy is reduced, and the service life of the equipment is improved. Moreover, such design improves the contact quality, and also reduces the production cost and complexity accordingly.

[0056] The target pipe 100 is a pipe in the liquid heating assembly that needs to be heated, usually a pipe through which water or other fluids flow. The heat-conducting sleeve 200 is a tubular structure that is sleeved on the outer surface of the target pipe 100, used to protect the target pipe 100 and serve as a medium for heat transfer, and the heat-conducting sleeve 200 is used to be fixedly connected with the heat-conducting connector 300, wherein the fixedly connected manner includes welding, and it needs to be noted that in addition to welding, the heat-conducting sleeve 200 can also be connected to the first groove 310 in other ways, for example, the heat-conducting sleeve 200 is connected to the first groove 310 by adhesive. The heat-conducting sleeve 200 not only protects the target pipe 100 from the external environment, but also transfers heat from the heat-generating part 400 to the target pipe 100 through its good heat-conducting performance, improving the heating efficiency.

[0057] The heat-conducting connector 300 is a component for connecting the heat-conducting sleeve 200 and other components (such as the heat-generating part 400), and the first groove 310 enables the heat-conducting sleeve 200 to be more firmly fixed in the assembly, reducing the difficulty of welding and improving the welding quality. The heat-conducting sleeve 200 does not need to be punched out with a relatively wide welding surface, reducing the step of punching the heat-conducting sleeve 200 and reducing the possibility of deformation of the target pipe 100, avoiding the possibility of a gap between the target pipe 100 and the heat-conducting sleeve 200 due to punching.

[0058] The heat-generating part 400 is a component that generates heat, usually by converting electrical energy or other energy into heat energy, for heating the target pipe 100 and the fluid therein.

[0059] At the same time, due to the reduction of the deformation of the target pipe 100, the problem of scale accumulation during the heating process is also effectively alleviated. The water flow is smoother when passing through the smooth and non-deformed pipe, reducing the generation of turbulent flow and vortex flow, thereby reducing the deposition speed of minerals and impurities. This not only helps to maintain the cleanliness of the pipe and the stability of the heat transfer performance, but also prolongs the service life of the heat-generating part 400 and reduces the maintenance cost.

[0060] According to one embodiment of the present application, the heat-conducting sleeve 200 is a circular heat-conducting sleeve, and the shape of the first groove 310 is matched with the shape of the outer surface of the heat-conducting sleeve 200. The shape of the first groove 310 is accurately matched with the shape of the outer surface of the heat-conducting sleeve 200, which can ensure that the heat-conducting sleeve 200 can be accurately and faultlessly embedded in the first groove 310, facilitating subsequent welding, and can increase the contact area, thereby simplifying the manufacturing process and reducing the impact on the target pipe 100 (no need to punch).

[0061] The heat and pressure generated during the welding process can be more evenly distributed on the contact surface. This uniform stress helps to reduce the welding stress concentration phenomenon, further reducing the risk of deformation of the target pipe 100 due to the welding process.

[0062] According to an embodiment of the present application, the heat-conducting sleeve 200 is a circular heat-conducting sleeve, and the radius R1 of the first groove 310 is greater than or equal to the radius R2 of the heat-conducting sleeve 200.

[0063] It can be understood that, since the radius R1 of the first groove 310 is greater than or equal to the radius R2 of the heat-conducting sleeve 200, the heat-conducting sleeve 200 can be partially embedded in the first groove 310 during the welding process. The first groove 310 can increase the contact area between the heat-conducting sleeve 200 and the heat-conducting connector 300, thereby improving the strength and stability of the welding position.

[0064] When the heat-conducting sleeve 200 is embedded in the first groove 310, the side wall of the first groove 310 can exert a certain radial support force on the heat-conducting sleeve 200. This support force helps to limit the radial expansion or deformation of the heat-conducting sleeve 200 during the welding process.

[0065] According to an embodiment of the present application, the depth H1 of the first groove 310 is less than or equal to the radius R2 of the heat-conducting sleeve 200.

[0066] It can be understood that, since the depth H1 of the first groove 310 is less than or equal to the radius R2 of the heat-conducting sleeve 200, it means that, during the welding process, the heat-conducting sleeve 200 will not be completely embedded in the first groove 310, but will maintain a certain exposed portion. By limiting the depth H1 of the first groove 310, it helps to reduce the welding difficulty between the heat-conducting sleeve 200 and the first groove 310, and the welding between the heat-conducting sleeve 200 and the first groove 310 is more stable.

[0067] According to an embodiment of the present application, the first side of the heat-conducting connector 300 is opposite to the second side of the heat-conducting connector 300.

[0068] It can be understood that, since the first groove 310 enables the heat-conducting sleeve 200 to be firmly welded to the first side of the heat-conducting connector 300, it ensures a stable connection between the heat-conducting connector 300 and the heat-conducting sleeve 200, and the heat-generating element 400 is arranged on the opposite second side of the heat-conducting connector 300, which can directly transfer heat to the heat-conducting connector 300, and then to the heat-conducting sleeve 200 and the target pipeline 100 through the heat-conducting connector 300. This layout reduces thermal resistance and improves heat conduction efficiency, so that heat can be transferred to the target pipeline 100 or medium more quickly, thereby improving the heating effect.

[0069] According to an embodiment of the present application, please refer to Figures 6 to 8 The second side of the heat-conducting connector 300 is provided with a second groove 320, and the heat-generating element 400 is fixedly connected to the second groove 320.

[0070] It can be understood that the second groove 320 helps to reduce the thermal resistance between the heat generating element 400 and the heat conducting connector 300. By optimizing the shape, size and material of the groove, heat can be more smoothly transferred from the heat generating element 400 to the heat conducting connector 300, and further to the target pipe 100 or medium.

[0071] Moreover, the presence of the second groove 320 makes the installation process of the heat generating element 400 more simple and fast. The operator only needs to align the heat generating element 400 with the groove and fix it, without the need for complex adjustment or positioning steps. This reduces the installation difficulty and improves the installation efficiency.

[0072] It should be noted that the provision of the second groove 320 also facilitates the subsequent welding and fixing between the heat generating element 400 and the heat conducting connector 300. The heat generating element 400 does not need to be punched out with a relatively wide welding surface, reducing the step of punching the heat generating element 400 and reducing the manufacturing difficulty.

[0073] According to an embodiment of the present application, the heat generating element 400 is a circular heat generating pipe, and the shape of the second groove 320 is adapted to the shape of the heat generating element 400.

[0074] It can be understood that the shape of the second groove 320 and the shape of the heat generating element 400 are adapted to ensure that the heat generating element 400 can be accurately and accurately embedded in the second groove 320, facilitating subsequent welding, and can increase the contact area, thereby simplifying the manufacturing process and reducing the impact on the target pipe 100 (without the need for punching).

[0075] According to an embodiment of the present application, the outer surface of the heat generating element 400 is a circular pipe structure, and the radius R3 of the second groove 320 is greater than or equal to the radius R4 of the heat generating element 400.

[0076] It can be understood that since the radius R3 of the second groove 320 is greater than or equal to the radius R4 of the heat generating element 400, the heat generating element 400 can be partially embedded in the second groove 320 during welding. The second groove 320 can increase the contact area between the heat generating element 400 and the heat conducting connector 300, thereby improving the strength and stability of the welding position.

[0077] When the heat generating element 400 is embedded in the second groove 320, the side wall of the second groove 320 will exert a certain radial support force on the heat generating element 400. This support force helps to limit the radial expansion or deformation of the heat generating element 400 during welding.

[0078] According to an embodiment of the present application, the depth H2 of the second groove 320 is less than the radius R4 of the heat generating element 400.

[0079] It can be understood that the depth H2 of the second groove 320 is less than or equal to the radius R4 of the heat-conducting sleeve 200, which means that during the welding process, the heating element 400 will not be completely immersed in the second groove 320, but will maintain a certain exposed portion. By limiting the depth H1 of the second groove 320, it helps to reduce the welding difficulty between the heating element 400 and the second groove 320, and the welding between the heat-conducting sleeve 200 and the first groove 310 is more stable.

[0080] According to an embodiment of the present application, the target pipe 100 is a stainless steel pipe. It can be understood that the stainless steel pipe can maintain stable performance for a long time in various harsh environments (such as high temperature, high pressure, humidity, corrosive medium, etc.), and is not easy to rust or corrode. And the stainless steel pipe material is non-toxic, odorless, and will not pollute the transported medium.

[0081] According to an embodiment of the present application, the heat-conducting sleeve 200 is an aluminum pipe. It can be understood that aluminum is a lightweight metal with a density much lower than commonly used pipe materials such as stainless steel. When the aluminum pipe is used as the heat-conducting sleeve 200, it can significantly reduce the weight of the entire system, facilitating installation, transportation and maintenance.

[0082] Aluminum has good processing performance and can be processed into various shapes and sizes of heat-conducting sleeves 200 through cutting, stamping, bending and other processes.

[0083] In addition, aluminum is an excellent heat conductor, and when the aluminum pipe is used as the heat-conducting sleeve 200 in combination with the heating element 400, it can more effectively transfer the heat generated by the heating element 400 to the target pipe 100 (such as a stainless steel pipe), improving heating efficiency.

[0084] According to an embodiment of the present application, the heat-conducting connecting piece 300 is an aluminum plate connecting piece. It can be understood that the aluminum plate has good processing performance and can be processed into various shapes and sizes of heat-conducting connecting pieces through cutting, stamping, bending and other processes.

[0085] In addition, aluminum is an excellent heat conductor, and when the aluminum pipe is used as the heat-conducting sleeve 200 in combination with the heating element 400, it can more effectively transfer the heat generated by the heating element 400 to the target pipe 100 (such as a stainless steel pipe), improving heating efficiency.

[0086] According to an embodiment of the present application, the target pipe 100 is a straight pipe or a bent pipe.

[0087] It can be understood that the straight pipe is one of the most common forms of pipe systems and is widely used in various fluid conveying, gas transmission and other scenarios. The bent pipe is suitable for scenarios where the flow direction of the fluid needs to be changed or obstacles need to be bypassed. The target pipe 100 is a straight pipe or a bent pipe, so that the system designer can flexibly plan the layout according to the actual needs.

[0088] The bent pipe can be a U-shaped pipe, a V-shaped pipe or a spiral pipe.

[0089] It should be noted that the target pipe 100 can be a straight pipe or a special-shaped bent pipe, as long as the first groove 310 on the connecting plate corresponds to the shape of the target pipe 100.

[0090] According to an embodiment of the present application, the cross-sectional shape of the target pipe 100 is unchanged.

[0091] It can be understood that the pipe with unchanged cross-sectional shape is more stable in structure and is not easy to deform or damage due to external force. This helps to ensure the long-term stable operation of the pipe system, reduces the downtime and maintenance cost caused by pipe failure.

[0092] The pipe with unchanged cross-sectional shape is easier to realize standardized design, thereby simplifying the manufacturing process and improving product quality and consistency.

[0093] Of course, in some embodiments, the cross-sectional shape of the target pipe 100 changes, which can be a larger cross-sectional area or a smaller cross-sectional area, or a circular cross-section to a square cross-section and other special-shaped cross-sections.

[0094] The liquid heating container according to the second aspect of the present application comprises a container body, a water pump assembly and the above-mentioned liquid heating assembly. The water pump assembly is connected to the container body, and the liquid heating assembly is arranged at the bottom of the container body.

[0095] The container body is used to contain the liquid to be heated. The water pump assembly is used to draw the liquid stored outside from the water pipe and deliver it to the inside of the container body. At the same time, the water pump assembly is also equipped with related pipes and valves to ensure the smooth flow and accurate control of the liquid. The liquid heating assembly is used to heat the liquid inside the container body. Since the liquid heating assembly is located at the bottom of the container body, it can directly heat the liquid in the container, reducing the loss in the heat transfer process and improving the heating efficiency.

[0096] It should be noted that the liquid heating container of the present application has a flexible heating mode. When the water pump is not working, the container can be heated by the heating pipe (i.e. the main heating mode) to meet the basic heating demand. When the water pump is working, the auxiliary heating mode can be selected to make up for the deficiency of the heating pipe or to improve the heating speed. This flexible heating mode can be adjusted according to different use requirements.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of claims of the present application.
