[0037] A water heater is a common household water heating device that uses electricity to heat tap water or water of suitable quality to a set temperature for daily use. In the related art, the heat exchanger of the water heater is unevenly distributed, resulting in uneven heat exchange in the water tank, low heat exchange efficiency, and slow heating, which leads to slow heating speed of the water heater, and cannot meet the user's demand for quick hot water, and may also generate a lot of energy waste.

[0038] The embodiments of the present utility model refer to Figure 1-Figure 6 As shown, a water tank of a water heater and a water heater are provided.

[0039] According to an embodiment of the present utility model, please refer to Figure 1 and Figure 2 The water tank of the water heater according to the embodiment of the utility model includes a box body 100, which is formed with a liquid storage space 110; a heater 200 is arranged in the box body 100, and is used to heat the liquid storage space 110; a heat exchange tube 300, the heat exchange tube 300 is arranged in the liquid storage space 110 to exchange heat with the liquid storage space 110, and the heat exchange tube 300 includes a first heat exchange section 310 and a second heat exchange section 320 that are interconnected, the first heat exchange section 310 is arranged corresponding to the heater 200, and the second heat exchange section 320 is arranged corresponding to the liquid storage space 110 outside the heater 200.

[0040] It can be understood that in this embodiment, the box body 100 forms a liquid storage space 110, and the heater 200 is arranged in the liquid storage space 110. The main function of the heater 200 is to convert electrical energy or other energy forms into thermal energy and transfer the thermal energy to the surrounding water to heat the water in the liquid storage space 110.

[0041] Exemplarily, the type and structure of the heater 200 include, but are not limited to, a glass tube, a quartz tube heater 200 or a water inlet heater 200, etc., which can be selected according to specific application scenarios and design requirements, and this embodiment does not specifically limit this.

[0042] The heat exchange tube 300 is divided into a first heat exchange section 310 and a second heat exchange section 320. The first heat exchange section 310 is directly corresponding to the heater 200 and is arranged near the heater 200. When water flows through the first heat exchange section 310, it absorbs heat energy from the heater 200 to achieve a rapid increase in water temperature. The first heat exchange section 310 is directly located near the heater 200, so that the heat generated by the heater 200 can be quickly and directly transferred to the water flow near the heater 200, and the water channel near the heater 200 then transfers the heat to the first heat exchange section 310 for heat exchange. This direct heat exchange method avoids long-distance heat transfer and possible heat loss, thereby improving the efficiency of heat exchange; at the same time, since the heater 200 is close to the first heat exchange section 310, the heat of the heater 200 can also be partially radiated to the first heat exchange section 310. This radiant heat conduction method can further heat the water flow passing through the first heat exchange section 310 and improve the heat exchange efficiency.

[0043] The second heat exchange section 320 is arranged corresponding to the liquid storage space 110 outside the heater 200. When water flows through the second heat exchange section 320, it will exchange heat with the hot water in the liquid storage space 110, thereby further increasing the water temperature. This design utilizes the heat of the already heated water in the liquid storage space 110, making the water temperature in the entire liquid storage space 110 more uniform.

[0044] It is understandable that the parameters such as the structure and shape of the first heat exchange section 310 and the second heat exchange section 320 may be the same or different, and this embodiment does not specifically limit this.

[0045] In this embodiment, the heat exchange tube 300 can exchange heat with the liquid storage space 110. During the operation of the water heater, the heater 200 is responsible for heating the water in the liquid storage space 110 in the box 100 to a set temperature. However, when the user needs to use hot water, the water is not taken directly from the liquid storage space 110, but the heat exchange between water and water is realized through the heat exchange tube 300.

[0046] Specifically, the housing 100 may be provided with a water inlet pipe and a water outlet pipe, one end of the heat exchange tube 300 is connected to the water inlet pipe, and the other end is connected to the water outlet pipe. When the user turns on the water heater, cold water enters the water heater through the water inlet pipe and first flows through the first heat exchange section 310 of the heat exchange tube 300. Since the first heat exchange section 310 is adjacent to the heater 200, the water temperature here is relatively high, and the cold water will quickly absorb heat here and begin to heat up. Then, the water that has been preliminarily heated will flow through the second heat exchange section 320, which is located in the liquid storage space 110 outside the heater 200. Here, the water will exchange heat with the hot water in the liquid storage space 110, further absorbing heat, so that the water temperature continues to rise.

[0047] Through this heat exchange method, users can obtain hot water with suitable temperature and ready to use without waiting for the water in the entire liquid storage space 110 to be heated to the set temperature. At the same time, since the heat exchange tube 300 is used for heat exchange, the freshness of the hot water can be ensured, avoiding the problem of bacterial growth and water quality degradation caused by long-term storage.

[0048] The water tank of the water heater according to the embodiment of the utility model includes a tank body 100, a heater 200 and a heat exchange tube 300, which are also provided with a liquid storage space 110; the heater 200 is arranged in the tank body 100 to heat the liquid storage space 110; the heat exchange tube 300 is arranged in the liquid storage space 110 and can exchange heat with the liquid storage space 110, and the heat exchange tube 300 includes a first heat exchange section 310 and a second heat exchange section 320 which are interconnected, the first heat exchange section 310 is arranged corresponding to the heater 200, and the second heat exchange section 320 is arranged corresponding to the liquid storage space 110 outside the heater 200. The first heat exchange section 310 is set corresponding to the heater 200. When water flows through the first heat exchange section 310, it will directly absorb heat energy from the heater 200, thereby achieving rapid heating and improving heating efficiency. The second heat exchange section 320 is set corresponding to the liquid storage space 110 outside the heater 200. When water flows through the second heat exchange section 320, it can exchange heat with the hot water in the liquid storage space 110, thereby further increasing the water temperature, making the heat exchange in the entire liquid storage space 110 more uniform, avoiding local overheating or overcooling, and improving the heat exchange efficiency of the heat exchange tube 300.

[0049] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the heater 200 includes a plurality of heating tubes 210 arranged side by side, and the first heat exchange section 310 is arranged around the outside of the plurality of heating tubes 210 .

[0050] It can be understood that in this embodiment, when the heater 200 includes a plurality of heating tubes 210 arranged side by side, and the first heat exchange section 310 is arranged around the outside of these heating tubes 210, the heat exchange efficiency and the uniform distribution of heat can be improved, thereby improving the heating efficiency and performance of the water heater.

[0051] Specifically, each heating tube 210 is responsible for converting electrical energy or other forms of energy into thermal energy, thereby heating the water flowing through it. By arranging multiple heating tubes 210 side by side, the total heating area can be increased, so that more water can be heated per unit time, thereby increasing the output of hot water.

[0052] The first heat exchange section 310 surrounds the outside of the heating tubes 210, which means that when the water flows through the first heat exchange section 310, it can simultaneously exchange heat with multiple heating tubes 210 and the water around the heating tubes 210. This surrounding design ensures sufficient heat exchange between the water flow and the heating tubes 210, and improves the efficiency of heat exchange. In addition, the surrounding first heat exchange section 310 can also be flexibly adjusted and optimized according to the number and arrangement of the heating tubes 210. For example, the number of heating tubes 210 can be increased or decreased, or the arrangement of the heating tubes 210 can be changed to meet different hot water needs and installation spaces.

[0053] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, a plurality of heating tubes 210 are arranged side by side in the liquid storage space 110 , and the first heat exchange section 310 is spirally wound around the outer sides of the plurality of heating tubes 210 .

[0054] It can be understood that in this embodiment, the spiral first heat exchange section 310 can be tightly wound around the outer side of the annular heating tube 210 along the length direction of the heating tube 210. The design of the winding tube increases the pipe length of the first heat exchange section 310, thereby increasing the heat exchange area with the surrounding hot water and the heating tube 210. Heat can be transferred from the heating tube 210 and the nearby hot water to the water flow in the first heat exchange section 310 more quickly, fully and effectively, thereby accelerating the heat exchange speed of the water, improving the efficiency of heat exchange, reducing energy waste, and improving the energy efficiency of the water heater.

[0055] And through the spiral winding design of the first heat exchange section 310, the water flow is guided to flow around the heating tube 210, forming a complex but orderly flow path. This flow path helps the cold water in the first heat exchange section 310 and the hot water in the liquid storage space 110 to exchange more evenly, avoiding local overheating or overcooling.

[0056] In addition, the spiral winding design of the first heat exchange section 310 cooperates with the heating tube 210 to play a role similar to an energy gathering chamber, that is, heat can be concentrated in a relatively small space to achieve more efficient energy conversion. Heat can be transferred to the cold water in the first heat exchange section 310 in a more concentrated manner, thereby improving the heat exchange efficiency.

[0057] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the heater 200 is disposed at the bottom of the liquid storage space 110 , and at least a portion of the second heat exchange section 320 is disposed corresponding to the top of the liquid storage space 110 .

[0058] It can be understood that in this embodiment, since the heater 200 is located at the bottom, the liquid in the liquid storage space 110 will produce natural convection after heating, the hotter liquid rises, and the colder liquid sinks, forming a circulating flow. This natural convection helps to distribute the heat more evenly throughout the liquid storage space 110. The heater 200 at the bottom can quickly heat the bottom liquid and transfer the heat to the entire liquid storage space 110 through natural convection, so that the liquid in the liquid storage space 110 can be heated to the set temperature more quickly.

[0059] In an optional embodiment, the second heat exchange section 320 is arranged corresponding to the top of the liquid storage space 110, and the heat generated by the rising liquid can be used for further heat exchange, which not only helps to further improve the heating efficiency, but also ensures that the heat of the liquid at the top of the liquid storage space 110 can also be fully exchanged by the heat exchange tube 300.

[0060] In this embodiment, by combining bottom heating and top heat exchange, this design can utilize heat energy more efficiently and reduce energy waste, which can not only improve the energy efficiency of the water heater but also reduce operating costs.

[0061] According to one embodiment of the present invention, referring to Figure 4 As shown, there are multiple heaters 200 , and the multiple heaters 200 are arranged at intervals along the height direction of the liquid storage space 110 .

[0062] It is understandable that in this embodiment, by arranging the heaters 200 at intervals in the height direction, heat can be generated simultaneously at different height layers of the liquid storage space 110, which helps to achieve uniform heating of the liquid in the liquid storage space 110 and reduce the temperature gradient. Multiple heaters 200 working simultaneously can increase the temperature of the liquid in the liquid storage space 110 more quickly. Compared with a single heater 200, the distribution of multiple heaters 200 can more effectively utilize energy and improve heat exchange efficiency.

[0063] On the other hand, multiple heaters 200 allow for more flexible control of the heating process of the water heater. By independently controlling the opening and closing of each heater 200, the heating power and heating speed can be adjusted as needed to meet the needs of different users or different time periods. The dispersed layout of multiple heaters 200 can reduce the risk of overheating of a single heater 200. If one heater 200 fails or overheats, the other heaters 200 can still continue to work to ensure the normal operation of the water heater and the safety of the user. And the design of multiple heaters 200 can adapt to liquid storage spaces 110 of different capacities and sizes. By adjusting the number and position of the heaters 200, it can be customized according to actual needs, improving the flexibility and applicability of the water heater.

[0064] In this embodiment, each heater 200 may be provided with a corresponding first heat exchange section 310 to ensure that heat can be quickly and directly transferred to the liquid flowing through the first heat exchange section 310, significantly improving the efficiency of heat exchange, accelerating the heating speed, and allowing users to enjoy hot water faster.

[0065] According to one embodiment of the present invention, referring to Figure 4 As shown, a second heat exchange section 320 is disposed in a gap between at least two of the plurality of heaters 200 .

[0066] It can be understood that in this embodiment, when there are multiple heaters 200, the heat exchange area of ​​the entire water heater system can be increased by setting a second heat exchange section 320 in the gap between the heaters 200, that is, more heat can be transferred to the heat exchange tube 300 through these additional heat exchange sections, thereby improving the efficiency of heat exchange.

[0067] The second heat exchange section 320 arranged in the gap between the heaters 200 can fully exchange heat with the hot water in the liquid storage space 110 between the two heaters 200, thereby reducing the energy consumption of the water heater, saving energy, and also reducing heat accumulation and the risk of overheating, thereby enhancing the safety performance of the water heater.

[0068] In an optional specific embodiment, the number of heaters 200 is two, and each of the two heaters 200 is correspondingly provided with a first heat exchange section 310 to maximize the heat exchange efficiency between heat and the liquid in the liquid storage space 110, and a second heat exchange section 320 is also provided between the two heaters 200 to further capture and transfer heat, optimize the distribution and utilization of heat, and improve the heat exchange efficiency.

[0069] In other embodiments, the number of heaters 200 can be 3 or more, and each heater 200 is still provided with a first heat exchange section 310 to ensure that heat can be directly and efficiently exchanged with the liquid. In the gaps between adjacent heaters 200, multiple second heat exchange sections 320 can be provided to further enhance the transfer and distribution of heat and improve the energy efficiency ratio of the water heater.

[0070] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the second heat exchange section 320 is formed with multiple heat exchange layers 321 that are connected in sequence, and the multiple heat exchange layers 321 are spaced apart along the height direction of the liquid storage space 110 .

[0071] It can be understood that, in this embodiment, the second heat exchange section 320 is formed with multiple heat exchange layers 321 connected in sequence, and the multiple heat exchange layers 321 are spaced apart along the height direction of the liquid storage space 110 to achieve more efficient heat transfer and more sufficient heat exchange.

[0072] Specifically, the design of the multi-layer heat exchange layer 321 allows the water in the second heat exchange section 320 to gradually heat up when flowing through different layers, thereby improving the efficiency of heat exchange. The multi-layer heat exchange layer 321 increases the heat exchange area, so that heat can be transferred to the liquid in the heat exchange tube 300 more quickly, thereby improving the overall heating efficiency. The design of the multi-layer heat exchange layer 321 can be adjusted according to the size and shape of the liquid storage space 110 to accommodate water heaters of different capacities and sizes. This flexibility enables the water heater to adapt to a wider range of application scenarios. Efficient and sufficient heat exchange helps to reduce the energy consumption of the water heater and reduce energy waste.

[0073] According to one embodiment of the present invention, referring to Figure 2 and Figure 5 As shown, each heat exchange layer 321 includes multiple straight pipe sections 3211 and multiple curved pipe sections 3212 . The multiple straight pipe sections 3211 are arranged side by side in the horizontal direction of the liquid storage space 110 , and two adjacent rows of straight pipe sections 3211 are connected end to end through the curved pipe sections 3212 .

[0074] It is understandable that in this embodiment, the multiple straight pipe sections 3211 in each heat exchange layer 321 are arranged side by side in the horizontal direction of the liquid storage space 110, which helps to increase the contact area with the liquid, thereby transferring heat more efficiently. At the same time, the two adjacent rows of straight pipe sections 3211 are connected end to end through the curved pipe sections 3212. This design allows hot water to form a continuous flow path when flowing through different layers of heat exchange layers 321, further promoting sufficient absorption of heat.

[0075] The multiple straight pipe sections 3211 increase the contact area with the liquid, so that heat can be transferred to the liquid more quickly, thereby improving the heat exchange efficiency. Through the combination of the multiple straight pipe sections 3211 and the curved pipe sections 3212, hot water can form a complex flow path when flowing through the heat exchange layer 321, which helps to achieve more sufficient heat exchange in the liquid storage space 110. Since the heat is more fully utilized and more evenly distributed, the energy consumption of the water heater can be reduced, which is not only beneficial to saving energy, but also helps to reduce the user's operating costs; and the design of the curved pipe section 3212 can also increase the structural stability of the heat exchange layer 321 to a certain extent.

[0076] According to one embodiment of the present invention, referring to Figure 2 and Figure 6 As shown, the electric water heater includes a support frame 330 , which is disposed in the liquid storage space 110 and is used to support the heat exchange tube 300 .

[0077] It is understandable that, in this embodiment, the main function of the support frame 330 is to support and fix the heat exchange tube 300, ensure that the heat exchange tube 300 works stably in the liquid storage space 110, and prevent it from moving or deforming due to water flow impact or other external forces. The support frame 330 can improve the structural stability of the entire electric water heater, especially in a high-temperature working environment, and can prevent structural deformation or damage caused by factors such as thermal expansion and contraction. Through a reasonable design of the support frame 330, the layout of the heat exchange tube 300 in the liquid storage space 110 can be optimized, so that it can more effectively utilize space and improve heat exchange efficiency.

[0078] Furthermore, the support frame 330 may be designed according to the distribution shapes and structures of the first heat exchange section 310 and the second heat exchange section 320 , respectively, so as to fully support the first heat exchange section 310 and the second heat exchange section 320 .

[0079] According to one embodiment of the present invention, referring to Figure 1 and Figure 3 As shown, the box body 100 is provided with an exhaust channel 120, and the exhaust channel 120 connects the space above the liquid surface in the liquid storage space 110 with the outside.

[0080] Conventional water heaters will expand the liquid in the water tank during the heating process, thereby applying pressure to the water tank. For the safety of the equipment, expansion space is often reserved in the water tank, which limits the design of the water tank structure. For example, the cross-section of the water tank is usually designed to be circular. In this embodiment, the exhaust channel 120 is provided so that the space above the liquid surface in the liquid storage space 110 can be connected to the external atmosphere. This allows the expansion pressure of the liquid in the liquid storage space 110 to be discharged through the exhaust channel 120 when the liquid is heated, avoiding the need for the box body 100 to adopt a pressure-bearing structure design. A square or other shape can be adopted, which allows the box body 100 in this embodiment to be designed to be smaller in size, reducing the space occupied by the water heater.

[0081] An embodiment of a second aspect of the utility model provides a water heater, a water tank of the water heater of any one of the above embodiments.
