The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.
[0054] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0055] Reference Figure 1 、 Figure 3 and Figure 4 As shown, a heating assembly 1000 according to an embodiment of the present invention is applied to hot water equipment, in particular, high-power instant hot water equipment, such as instant water heaters, instant hot water dispensers, smart toilets, bathroom fixtures, etc. The heating assembly 1000 according to the embodiment of the present invention includes a plurality of cup bodies 100 and heating elements 200 connected to the plurality of cup bodies 100. There are a plurality of heating elements 200, and the plurality of heating elements 200 are respectively connected to the plurality of cup bodies 100 to heat the liquid in the plurality of cup bodies 100. The plurality of cup bodies 100 are arranged in parallel to form a parallel heating cup structure. The parallel arrangement here can be understood as a structure in which the plurality of cup bodies 100 are arranged side by side, one end of the plurality of cup bodies 100 is respectively connected to the water inlet pipe, and the other end of the plurality of cup bodies 100 is connected to the water outlet pipe. Each cup 100 has a water passage chamber 110 within it. Water flows through this chamber, and the heating element 200 heats the water, heating the cold water into hot water. The parallel heating cup structure allows multiple heating elements 200 to operate under normal loads, and by operating the multiple heating cups simultaneously, a high flow of hot water can be provided.
[0056] Reference Figure 2 、 Figure 3 and Figure 4 As shown, it can be understood that the heating component 1000 of the embodiment of the present invention also includes a water inlet pipe 300 and a water outlet 400. The water inlet pipe 300 is connected to the multiple cup bodies 100 respectively. The water inlet pipe 300 can be connected to the outer walls of the multiple cup bodies 100 in sequence, or can be passed through the multiple cup bodies 100 in sequence, or divided into multiple branches and each branch is passed through the multiple cup bodies 100 respectively, which is no longer specifically limited here.
[0057] The water inlet pipe 300 is provided with a plurality of drainage holes 310. Each water passage cavity 110 is connected to the water inlet pipe 300 via at least one drainage hole 310. In other words, one or more drainage holes 310 may be provided in the water passage cavity 110 of each cup body 100, and this is not specifically limited herein. In this embodiment, the plurality of drainage holes 310 are connected to the water passage cavity 110 of the cup body 100 in a one-to-one correspondence. The drainage holes 310 are used to fill the water passage cavity 110 with water. Furthermore, the drainage holes 310 are configured to allow water from the water inlet pipe 300 to flow evenly through the plurality of cup bodies 100, thereby reducing differences in flow rate and pressure between the plurality of cup bodies 100, resulting in more uniform heating and improving the heating performance of the heating assembly 1000.
[0058] Reference Figure 4 As shown, it can be understood that a connecting pipe 500 is provided between adjacent cup bodies 100, and the connecting pipe 500 is used to connect adjacent water passage chambers 110, and the water outlet 400 and the water inlet pipe 300 are connected along the length direction of the cup body 100 (i.e. Figure 4 The water outlet 400 is arranged at intervals (in the middle and upper directions) to construct a plurality of heating cup structures arranged in parallel. For example, the water outlet 400 can be arranged in the middle or upper area of the cup body 100, and the water inlet pipe 300 is arranged in the lower area of the cup body 100. The water outlet 400 is connected to one of the cup bodies 100, or to one of the connecting pipes 500. The water outlet 400 is used to discharge the hot water in the multiple water passage chambers 110 out of the cup body 100, so that the liquid can complete the heat exchange through the multiple water passage chambers 110 respectively and then be discharged through the water outlet 400 at the same time, thereby increasing the heat exchange performance, increasing the water output, and improving the stability of the water outlet temperature. Moreover, the heating element 200 heats and raises the temperature of the water in the multiple cup bodies 100 respectively, reducing the workload of the heating element 200, making the failure rate of the heating element 200 low, and extending the service life.
[0059] It can be understood that the heating component 1000 of the embodiment of the present invention can avoid the short service life of the heating element 200, the burning of the wire, the bursting of the tube, the leakage of the heating element 200, etc., compared with the structure of multiple heating cups connected in series, and can also avoid the situation where the temperature of the inner tank rises when the water is turned off, and the user is suddenly scalded by the excessively high water temperature within a few seconds during normal use.
[0060] Reference Figure 4 and Figure 5As shown, it can be understood that the water inlet pipe 300 includes a diverter pipe section 330, a plurality of drainage holes 310 are provided in the diverter pipe section 330, and a plurality of cup bodies 100 are provided with corresponding through holes (not shown in the figure), and the diverter pipe section 330 is sequentially passed through the through holes of the plurality of cup bodies 100, so that the plurality of drainage holes 310 are respectively correspondingly provided in the plurality of water passage chambers 110. The design of the diverter pipe section 330 passing through the cup body 100 can increase the structural strength of the water inlet pipe 300, strengthen the stability of the connection between the water inlet pipe 300 and the cup body 100, and reduce the risk of the water inlet pipe 300 falling off or bending. Moreover, the outer wall of the diverter pipe section 330 and the cup body 100 is formed into a stable connection structure by welding, which is more convenient to process. Refer to Figure 6 As shown, the diverter pipe section 330 can be provided through the middle of the cup body 100. The end of the diverter pipe section 330 can be located inside the last cup body 100 in the direction of insertion, or can be extended out of the last cup body 100, without further limitation. The drainage holes 310 are provided in the water passage cavity 110, allowing water to be directly injected into the corresponding water passage cavity 110, reducing the risk of water leakage in the water inlet pipe 300.
[0061] Reference Figure 4 and Figure 5 As shown, it can be understood that the drainage hole 310 is opened on the tube wall of the diverter pipe section 330, and each cup body 100 is correspondingly provided with a drainage hole 310, and the drainage hole 310 is arranged toward the water outlet end of the cup body 100. The heating component 1000 guides the water flow through the drainage hole 310, so that the water flow forms a vortex on the inner wall of the cup body 100. The vortex can increase the contact area between the water and the surface of the heating element 200, increase the contact time between the water and the surface of the heating element 200, quickly take away the heat of the heating element 200, and reduce the heat density of the heating element 200 when working, thereby extending the service life of the heating element 200 and reducing the failure rate of the heating element 200. By connecting the diverter pipe section 330 through the lower part of the cup body 100, the drainage hole 310 can be designed with different apertures, different positions along the axial direction of the diverter pipe section 330, different positions along the circumferential direction of the diverter pipe section 330, and different orientations. Moreover, according to the structure and position of each cup body 100 of the heating component 1000, the drainage hole 310 is designed separately, so that the water inlet flow rate per unit time in the corresponding cup body 100 can be adjusted, thereby controlling the water flow rate passing through each cup body 100 per unit time to be the same, making the water inlet of each cup body 100 more uniform, reducing the difference in flow rate and pressure between multiple cup bodies 100, and making heating more uniform. The uniform distribution of water flow can play a key role in the control and safety of the heating component 1000.
[0062] It should be further explained that the heating component 1000 of an embodiment of the present invention adopts a split assembly structure of a water inlet pipe 300 and multiple cup bodies 100. Compared with the traditional one-piece molding structure, this embodiment can conveniently adjust the parameters of the multiple drainage holes 310 on the diversion pipe section 330, and then insert it into the cup body 100 to achieve assembly, thereby achieving individual adjustment of the water inlet flow of each cup body 100. The adjustment is more convenient, avoiding the disadvantage of the traditional one-piece molding structure that a new mold needs to be designed after each adjustment, saving mold costs and greatly reducing production costs.
[0063] Reference Figure 1 and Figure 4 As shown, it can be understood that the multiple cup bodies 100 are integrally formed, which has a higher structural strength, reduces the risk of water leakage, improves the quality of the product, and reduces the installation process and improves the assembly efficiency. It can be understood that the cup body 100 can be made of metal materials such as stainless steel and copper. Metal materials are easy to process and form, and have a stable structure and good durability. One end of the multiple cup bodies 100 along the length direction is the water inlet end. The water inlet pipe 300 is respectively connected to the water inlet end of the multiple cup bodies 100, so that the water flow of the water inlet pipe 300 can be more evenly distributed to each cup body 100. The heating element 200 heats the water flow of each cup body 100, so that the cold water is heated into hot water after passing through the water chamber 110, ensuring the stability of the water temperature at the water outlet 400.
[0064] Reference Figure 1 and Figure 2 As shown, it can be understood that the water inlet pipe 300 also includes an extension pipe section 340, one end of the extension pipe section 340 is connected to the diversion pipe section 330, and the other end of the extension pipe section 340 extends in the length direction of the cup body 100, so that the extension pipe section 340 can be Figure 1 The installation position is adjusted in the up and down directions as shown, which facilitates the position arrangement of the water inlet pipe 300 and enables the water inlet pipe 300 to adapt to the needs of different installation environments.
[0065] Reference Figure 1 and Figure 2 As shown, it can be understood that the water inlet pipe 300 also includes a bent pipe section 350, one end of the bent pipe is connected to the extension pipe section 340, and the other end of the bent pipe section 350 extends to a side away from the cup body 100. The bent pipe section 350 enables the water inlet pipe 300 to change its extension direction, that is, it can be Figure 1 The installation position is adjusted in the left and right directions as shown, which facilitates the position arrangement of the water inlet pipe 300 and enables the water inlet pipe 300 to adapt to the needs of more different installation environments.
[0066] Reference Figure 1 and Figure 2As shown, it can be understood that the heating component 1000 also includes a water inlet connector 320, the bent pipe section 350 is connected to the water inlet connector 320, and the water inlet connector 320 can be vertically arranged with the cup body 100 (such as Figure 1 As shown), the water inlet connector 320 can also be arranged in parallel with the cup body 100 (as shown Figure 9 As shown), the water inlet connector 320 can be installed in different directions according to different installation environments, making the installation versatility of the heating component 1000 stronger.
[0067] It is understandable that the heating element 200 can adopt structures such as heating tubes, heating wires, ceramic heaters, etc., which are not specifically limited here. The selection is made according to the actual needs of the product, for example, according to parameters such as water output per unit time, heating power, product size, etc.
[0068] Reference Figure 2 As shown, it can be understood that the heating element 200 includes a heating tube (not shown in the figure). The plurality of heating tubes are respectively located in the corresponding water passage chamber 110. The water inlet pipe 300 and the cup body 100 are connected along the length direction (i.e. Figure 2 The water inlet pipe 300 and the water outlet 400 are respectively located at the two ends of the cup body 100 along the length direction. For example, the water inlet pipe 300 is located in the lower area of the cup body 100, and the water outlet 400 is located in the upper area of the cup body 100. This design enables the water flow in each cup body 100 arranged in parallel to flow through the entire water flow cavity 110, and after sufficient heat exchange with the heating pipe, it converges to the end of the cup body 100 and is finally discharged through the water outlet 400. This makes the water flow passing through the heating assembly 1000 more evenly heated, the outlet water temperature more stable, and the water output greater.
[0069] Reference Figure 1 and Figure 2As shown, it can be understood that the water inlet pipe 300 is connected to the lower part of the cup body 100, and the water inlet pipe 300 is in communication with the water passage chamber 110. The water outlet 400 is connected to the upper part of the cup body 100, and the water outlet 400 is in communication with the water passage chamber 110. Water flows into the water passage chamber 110 through the lower area of the cup body 100, and the water flows from the bottom to the top, taking away the heat of the heating tube, and then discharges the water passage chamber 110 through the upper area of the cup body 100. The heating tube heats the water by convection, and the water temperature rises. The temperature of the upper part of the cup body 100 is high, and the temperature of the lower part of the cup body 100 is low. The heated hot water rises, and the unheated cold water is still in the lower part of the cup body 100. The water flow can effectively take away the heat from the surface of the heating tube. In addition, a water diversion channel structure or a structure with multiple heating tubes in parallel can be set in the cup body 100 to achieve the goal of increasing the area and time of heat convection when demanding high power and high flow, thereby meeting the requirements of instantaneous heating of water flow and improving user experience.
[0070] It is understood that the drainage holes 310 provided at the connection between the water inlet pipe 300 and the cup body 100 function to evenly distribute the water flow. With multiple cup bodies 100 connected in parallel, even water distribution plays a key role in the control and safety of the heating assembly 1000. Furthermore, when the heating tube utilizes convection heating, the water temperature in the lower middle portion of the cup body 100 is relatively low. However, when multiple cup bodies 100 are connected in parallel, the hot water mixes at the top, effectively reducing sudden temperature spikes, ensuring a more consistent and comfortable water temperature and further enhancing the user experience.
[0071] Reference Figure 4 As shown, it can be understood that the connecting pipe 500 is connected to the upper portion of the cup body 100 and is in communication with the water passage chambers 110 of the multiple cup bodies 100. The connecting pipe 500 allows the hot water flowing from the bottom to the top of the water passage chambers 110 of the multiple cup bodies 100 to converge at the upper portion of the cup body 100. After the hot water in the multiple cup bodies 100 is heated, it is mixed, thereby effectively reducing the difference in water flow temperature, avoiding the situation where the water flow temperature at the water outlet 400 suddenly rises, and making the temperature of the hot water discharged from the water outlet 400 more constant. It should be noted that the connecting pipe 500 is integrally formed with the multiple cup bodies 100, which has higher structural strength, reduces the risk of water leakage, improves product quality, and simplifies the installation process and improves assembly efficiency.
[0072] Reference Figure 1 and Figure 7As shown, it can be understood that the heating pipe is located in the water flow chamber 110, and the heating pipe is arranged in the center of the water flow chamber 110 to heat the water in the water flow chamber 110. The heating pipe can be a U-shaped structure or a spiral structure, and fins can also be provided on the surface of the heating pipe. The specific form of the heating pipe is not specifically limited here. A mounting head 210 is provided on the heating pipe, one end of the mounting head 210 is connected to the heating pipe, and the other end of the mounting head 210 is sealed and connected to the upper part of the cup body 100, and extends out of the cup body 100, and is connected to an external power source through a pin 220, thereby realizing power supply to the heating pipe.
[0073] Reference Figure 1 and Figure 2 As shown, it can be understood that the heating pipe is sealedly connected to the upper portion of the cup body 100, for example, by threading the mounting head 210 and the upper opening of the cup body 100 to prevent water leakage from the cup body 100 and improve the structural stability of the heating assembly 1000. In addition, it also facilitates the assembly between the cup body 100 and the heating pipe, thereby improving the efficiency of the production line.
[0074] Reference Figure 4 and Figure 6 As shown, it can be understood that the cup body 100 is a long columnar structure, and the heating tube is installed in the cup body 100, which reduces the amount of water that needs to be heated by the heating tube per unit time, so that the water and the heating tube can meet the effect of instantly heating the water under short-time contact.
[0075] It is understandable that a guide plate (not shown in the figure) is provided on the inner wall of the cup body 100, and the guide plate extends along the length direction of the cup body 100 and is spiral-shaped. The heating tube is arranged inside the cup body 100 to heat the water entering the water chamber 110. The guide plate surrounds the outside of the heating tube and forms a spiral diversion water channel (not shown in the figure) between the heating tube and the heating tube. The diversion water channel extends from the lower part of the cup body 100 to the upper part of the cup body 100, which can increase the contact area and contact time between the water flowing through the diversion water channel and the heating tube, so that the water can fully exchange heat with the heating tube during the spiral rising process. It should be noted that the water inlet pipe 300 is connected to the cup body 100 and communicated with the diversion water channel. The water inlet pipe 300 is used to transport water to the diversion water channel at the lower end of the interior of the cup body 100. The water outlet 400 is connected to the water passage chamber 110 and is located at the upper portion of the cup body 100. The water outlet 400 can transport water flowing from the lower portion of the cup body 100 to the outside of the cup body 100. Therefore, tap water injected from the water inlet pipe 300 continuously flows into the cup body 100 through the water inlet pipe 300. The water spirals upward from the lower end of the diversion channel to the upper end. As the water rises, the heating pipe continuously heats the flowing water, fully exchanging heat with the heating pipe. The heated hot water is then discharged from the cup body 100 through the water outlet 400 for the user to consume.
[0076] It can be understood that in order to cooperate with the spiral diversion water channel, the heating tube adopts a spiral structure heating tube, which can further increase the contact area and contact time between the water flowing through the diversion water channel and the heating tube, so that the water can fully exchange heat with the heating tube during the spiral rising process, and then effectively take away the heat from the surface of the heating tube, reduce the heat density of the heating tube when working, thereby reducing the failure rate of the heating tube and extending the service life of the heating tube.
[0077] Reference Figure 4 and Figure 6 As shown, it can be understood that the horizontal height of the water outlet 400 is greater than or equal to the horizontal height of the connecting pipe 500, which can enable the hot water in the water flow chambers 110 of multiple cup bodies 100 to converge and fully mix, and then be discharged through the water outlet 400, thereby making the water output more balanced and stable, and improving the user experience.
[0078] Reference Figure 1 and Figure 9 As shown, the water outlet 400 is integrally formed with the cup body 100, which has a higher structural strength, reduces the risk of water leakage, improves the quality of the product, and reduces the installation process and improves the assembly efficiency. The water outlet 400 can be connected to a water outlet connector 420 (such as Figure 1 As shown), the water outlet 400 may also be connected to a water outlet pipe 410 (as shown Figure 9As shown), the structural layout and installation requirements of the heating assembly 1000 can be met.
[0079] For example, refer to Figure 1 As shown, the heating assembly 1000 uses two cup bodies 100 arranged in parallel. The heating assembly 1000 is installed on the water heater. During the operation of the water heater, tap water enters the heating assembly 1000 through the water inlet pipe 300, and cold water is injected into the two cup bodies 100 through the drainage hole 310 of the water inlet pipe 300 to form two water flows. The two water flows circulate in the two cup bodies 100 at the same time, and heat is exchanged with the heating element 200 at the same time. The temperature of the water flow in the two cup bodies 100 increases from bottom to top. When it reaches the water outlet 400 and flows out, the heat exchange process of the water flow is completed, and the temperature of the water flow is rapidly increased. The embodiment of the present invention uses two parallel cup bodies 100. The two heating tubes are respectively located in the two cup bodies 100. The two heating tubes each share approximately the same electrical power and heat the circulating water at the same time. Under the same flow rate and heating tube power, the water outlet temperature at the top of the two cup bodies 100 is basically the same, so the power borne by the heating tubes of the two cup bodies 100 is also the same, which can effectively protect the heating component 1000.
[0080] Furthermore, the upper portions of the two cup bodies 100 are connected via a connecting pipe 500 so that the water passage chambers 110 of the two cup bodies 100 are connected. The water outlet 400 is connected to the upper portion of one of the cup bodies 100, and the water inlet pipe 300 is connected to the lower portions of the two cup bodies 100. This facilitates the structural layout of the heating assembly 1000, facilitates the arrangement of the positions of the water inlet pipe 300 and the water outlet 400, and facilitates the connection of the water inlet pipe 300 and the water outlet 400. Of course, depending on the product requirements, the water inlet pipe 300 and the water outlet 400 can also be connected to one of the cup bodies 100 at the same time, or be located on the same side of multiple cup bodies 100, which is not specifically limited here.

Two connecting pipes 500 are provided, one located between the upper portions of two of the cup bodies 100, thereby connecting the water passage 110 of the three cup bodies 100.

The water outlet 400 is located at the upper portion of the last cup body 100 along the direction in which the water inlet pipe 300 passes. The water outlet 400 and the connecting pipe 500 are located at the same horizontal height. Depending on the power and water volume requirements, the heating assembly 1000 may include four cup bodies 100, five cup bodies 100, or even more cup bodies 100 in parallel, which is not specifically limited here.
