[0060] A water heater is a common household hot water device that uses electrical heating to heat tap water or water of suitable water quality to a set temperature for daily use. In the related art, in order to guide the flow of water, the water tank of the water heater is provided with a water channel structure, and the water channel structure is generally provided at the bottom of the outer side of the inner tank 100, resulting in a large volume of the water tank and requiring a large installation space.

[0061] The embodiments of the present utility model refer to Figure 1-Figure 9 As shown, a water tank of a water heater and a water heater are provided.

[0062] According to an embodiment of the present utility model, please refer to Figure 1-Figure 3 As shown, the water tank of the water heater according to the embodiment of the utility model includes an inner tank 100, which forms a liquid storage space 110, and the inner tank 100 includes a side panel 130; a heater 200 is arranged in the inner tank 100 to heat the liquid storage space 110; a heat exchange tube 300 is arranged in the liquid storage space 110 to exchange heat with the liquid storage space 110; a water channel assembly 500, and the water channel assembly 500 is arranged on a side of the side panel 130 facing the liquid storage space 110, or the water channel assembly 500 is formed integrally with the side panel 130.

[0063] It can be understood that in this embodiment, the inner tank 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.

[0064] 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.

[0065] In this embodiment, reference Figure 4As shown, the side panel 130 may include a front panel 131, a rear cover plate 134, a left end plate 132 and a right end plate 133, and the front panel 131, the rear cover plate 134, the left end plate 132, the right end plate 133 and the top plate and the bottom plate are together arranged to form a liquid storage space 110.

[0066] In an alternative embodiment, reference Figure 3 As shown, the water channel assembly 500 is arranged on the side of the side panel 130 facing the liquid storage space 110. By arranging the water channel assembly 500 on the inner side of the side panel 130, the space occupied by the water channel assembly 500 is the liquid storage space 110 in the inner tank 100, and there is no need to occupy the space outside the inner tank 100, so that the water heater can save external space. On the other hand, it can also make more space for the space outside the inner tank 100 to carry out the expanded functions of the machine.

[0067] In another optional embodiment, referring to Figure 2 As shown, the water channel assembly 500 and the side panel 130 are integrally formed, which can also prevent the water channel assembly 500 from occupying an extra large space. Since the water channel assembly 500 and the side panel 130 are integrally formed, the extra connectors or pipes between them can be reduced, so the overall volume of the water heater can be greatly reduced, making it more compact. On the other hand, the one-piece design greatly reduces the number of connection points, and the one-piece water channel assembly 500 and the side panel 130 have better sealing performance, reducing the risk of water leakage or seepage. The one-piece structure simplifies the installation process of the water heater, and because potential failure points are reduced, subsequent maintenance is also easier.

[0068] 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 inner tank 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.

[0069] Specifically, the inner tank 100 can be provided with a water inlet pipe 101 and a water outlet pipe 102. One end of the heat exchange tube 300 is connected to the water inlet pipe 101, and the other end is connected to the water outlet pipe 102. When the user turns on the water heater, cold water enters the water heater through the water inlet pipe 101, 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.

[0070] 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.

[0071] According to the water tank of the water heater of the embodiment of the utility model, the water tank of the water heater includes an inner tank 100, a heater 200, a heat exchange tube 300 and a water channel assembly 500, the inner tank 100 forms a liquid storage space 110, and the inner tank 100 includes a side panel 130; the heater 200 is arranged in the inner tank 100 to heat the liquid storage space 110; the heat exchange tube 300 is arranged in the liquid storage space 110 to exchange heat with the liquid storage space 110; the water channel assembly 500, the water channel assembly 500 is arranged on the side of the side panel 130 facing the liquid storage space 110, or the water channel assembly 500 is formed integrally with the side panel 130. By arranging the water channel assembly 500 on the side of the side panel 130 facing the liquid storage space 110, the space occupied by the water channel assembly 500 is the liquid storage space 110 of the inner tank 100, and does not occupy the space outside the inner tank 100; or by integrally forming the water channel assembly 500 and the side panel 130, the additional external space occupation is avoided, and the occupied volume of the water tank of the water heater can be reduced, thereby realizing a compact design of the water heater.

[0072] According to one embodiment of the present invention, referring to Figure 1 As shown, the water tank of the water heater further includes a shell 700 , and a side of the side panel 130 facing away from the liquid storage space 110 and the shell 700 define a mounting cavity 710 for the functional module.

[0073] It can be understood that in this embodiment, an installation cavity 710 is formed between the side panel 130 and the outer shell 700, and the installation cavity 710 can be used to install other functional modules, which not only improves the functionality and practicality of the water heater, but also makes the entire device more modular, reduces the installation space, and facilitates installation, maintenance and upgrading.

[0074] The functional modules are centrally installed in the installation cavity 710, and the components and devices originally dispersed in various parts are integrated together, reducing the independent space required for each of them. Through reasonable layout and compact design, the space utilization rate of the entire installation cavity 710 is greatly improved. Therefore, the overall volume of the water heater is effectively compressed. And when the functional modules are centrally arranged, the connections and pipelines between them will also be reduced accordingly, which not only reduces the use of materials and manufacturing costs, but also further reduces the volume of the water heater.

[0075] On the other hand, the functional modules are centrally arranged in the installation cavity 710, making it easier to maintain and upgrade the water heater. When a module fails or needs to be upgraded, it is only necessary to open the installation cavity 710 and replace or upgrade the corresponding module, which is convenient for inspection and maintenance.

[0076] The design of the installation cavity 710 can also improve the safety of the water heater, because all functional modules are enclosed inside, reducing the impact and interference of external factors on them. At the same time, the installation cavity 710 can also play a safety protection role such as heat insulation, fire prevention, water and electricity separation, ensuring the safety of the water heater during operation.

[0077] Various types of functional modules can be installed in the installation cavity 710, including but not limited to a control panel, a temperature sensor, a safety valve, a water quality monitoring device, etc. These functional modules can expand the functions of the water heater, improve the user experience, and ensure the safe and stable operation of the water heater.

[0078] According to one embodiment of the present invention, referring to Figure 5 As shown, the functional module includes an electric control component 400 , a control valve 800 and an expansion component 600 , and the electric control component 400 , the control valve 800 and the expansion component 600 are arranged in parallel along the height direction of the side panel 130 .

[0079] It can be understood that in this embodiment, the electronic control component 400, the control valve 800 and the expansion component 600 are arranged in parallel along the height direction of the side panel 130, which can make full use of the vertical space of the water heater and reduce the thickness of the water tank. For example, the functional module can be arranged on the left end plate 132 or the right end plate 133 with a smaller area, thereby reducing the thickness of the water tank of the water heater in the front-to-back direction and reducing the occupied volume of the water heater.

[0080] Furthermore, arranging the electronic control component 400, the control valve 800 and the expansion component 600 in different areas helps to reduce electromagnetic interference and physical collisions between the components, thereby improving the stability and reliability of the overall operation.

[0081] The expansion component 600 may include various types, including but not limited to: Filtration module: used to remove impurities, particulate matter and suspended matter in water to improve the purity of water quality. Sterilization module: uses ultraviolet rays, ozone or other technologies to kill bacteria, viruses and other microorganisms in water to ensure the hygiene and safety of water quality. Water quality monitoring module: real-time monitoring of water quality parameters such as pH value, dissolved oxygen, turbidity, etc., so that users or systems can adjust as needed. Flow control module: adjusts the water flow to meet the needs of different application scenarios.

[0082] In the related art, the electric control component 400 is generally arranged at the bottom of the inner tank 100. When the water tank leaks, the circuit board is very easy to contact the water, thereby causing a series of safety problems and posing a great safety hazard. In this embodiment, the electric control component 400 can be arranged in the top area of ​​the side panel 130, which greatly reduces the chance of direct contact between the electric control component 400 and the leaking water, thereby reducing the risk of leakage. Even if a small amount of liquid overflows from the inside of the water tank, the isolation design of the electric control component 400 can effectively avoid the occurrence of short circuit phenomenon, ensuring the safe operation of the water heater.

[0083] In an optional embodiment, the electric control component 400 is disposed in the top area of ​​the side panel 130, and the interface of the water circuit assembly 500 is located below the electric control component 400, which can play the role of water and electricity partition isolation. The design of water and electricity partition reduces the possibility of power failure caused by water circuit problems. Even if the water circuit fails, it will not affect the normal operation of the power board, thereby ensuring the overall stability and reliability of the water heater.

[0084] According to one embodiment of the present invention, referring to Figure 1 and Figure 5 As shown, the inner tank 100 is provided with a water inlet pipe 101 and a water outlet pipe 102 connected to the water channel assembly 500, and the expansion assembly 600, the heater 200, the water inlet pipe 101 and the water outlet pipe 102 are installed side by side at the bottom of the side panel 130.

[0085] It is understandable that in this embodiment, the expansion component 600, the heater 200, the water inlet pipe 101 and the water outlet pipe 102 are installed side by side at the bottom of the side panel 130, so that the space at the bottom can be fully utilized to achieve a compact layout. The side-by-side arrangement can make the structure inside the entire water heater more compact and improve space utilization. In addition, the water inlet pipe 101 and the expansion component 600 are arranged side by side at the middle or bottom of the side panel 130, so that all related components can be centrally managed. The middle or bottom of the side panel 130 usually has more space, especially in the design of a compact water heater, so that the space can be fully utilized without affecting the layout of other key components.

[0086] In this embodiment, the expansion component 600 is designed as an independent module, which can realize modular production of the water heater. In this way, different expansion components 600 can be flexibly adjusted according to user needs and market changes to meet the needs of different users.

[0087] According to one embodiment of the utility model, combined Figure 6 and Figure 7 As shown, the side panel 130 includes an inner panel 1301 and an outer panel 1302 which are assembled with each other, and the waterway assembly 500 is formed between the inner panel 1301 and the outer panel 1302 .

[0088] The side panel 130 is split so that the channel of the water channel assembly 500 on the side panel 130 can be easily manufactured during the manufacturing process (for example, on the basis of injection molding and stamping, the channel can also be directly processed on the inner panel 1301 or the side panel 130 by machining); and the inner surface of the exhaust channel 120 can be easily disassembled and cleaned.

[0089] In this embodiment, the channel of the water channel component 500 is arranged on the inner panel 1301. Of course, the channel of the water channel component 500 can also be partially arranged on the inner panel 1301 and the other part arranged on the outer panel 1302; or the channel of the water channel component 500 can be arranged on the outer panel 1302 to ensure that its structural form is easy to process.

[0090] According to one embodiment of the utility model, combined Figure 6 and Figure 7 As shown, the inner enclosure plate 1301 is recessed away from the outer enclosure plate 1302 to form a waterway assembly 500 between the inner enclosure plate 1301 and the outer enclosure plate 1302 .

[0091] It can be understood that in this embodiment, the inner panel 1301 is recessed toward one side of the liquid storage space 110 to form the water channel assembly 500, so that the water channel assembly 500 is arranged toward the liquid storage space 110 of the inner tank 100, avoiding the additional occupation of the external space of the inner tank 100, and making the overall volume of the water heater more compact.

[0092] According to one embodiment of the utility model, combined Figure 6 and Figure 7 As shown, the inner panel 1301 is formed with a step surface 1303 , the outer panel 1302 is fixed to the step surface 1303 , and a sealing ring 140 is provided on the side of the inner panel 1301 facing away from the outer panel 1302 ; and / or, a sealing ring 140 is provided between adjacent side panels 130 .

[0093] In an optional embodiment, the inner panel 1301 is formed with a step surface 1303, and the outer panel 1302 is fixed on the step surface 1303. A sealing ring 140 is provided on the side of the inner panel 1301 facing away from the outer panel 1302. The sealing ring 140 ensures the sealing effect between the inner panel 1301 and the outer panel, thereby preventing the liquid in the liquid storage space 110 from leaking from the connecting gap between the inner panel 1301 and the outer panel 1302. In addition, the step surface 1303 expands the fitting area between the inner panel 1301 and the outer panel 1302, thereby improving the sealing and fixing effect between the two.

[0094] In this embodiment, the sealing ring 140 is adapted to the rectangular structure of the side panel 130 and is in a rectangular ring shape. Of course, the shape of the sealing ring 140 can be adaptively adjusted based on the side panel 130 of different shapes, and this embodiment does not make any specific limitation.

[0095] In another optional embodiment, a sealing ring 140 is provided between adjacent side panels 130 to ensure the sealing inside the water heater and prevent liquid leakage, and through the compression effect of the sealing ring 140, a tighter connection is formed between adjacent side panels 130, thereby enhancing the overall structural stability of the water heater.

[0096] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, the water channel assembly 500 includes: a water inlet channel 510, connecting the water inlet pipe 101 and the heat exchange pipe 300; a water outlet channel 520, connecting the heat exchange pipe 300 and the water outlet pipe 102; a sewage cavity 530, connecting the liquid storage space 110 with the outside to discharge the sewage in the liquid storage space 110; wherein the water inlet channel 510, the water outlet channel 520 and the sewage cavity 530 are formed on the same side panel 130.

[0097] It can be understood that in the present embodiment, a water inlet channel 510, a water outlet channel 520 and a sewage chamber 530 are integrally formed on the side panel 130, one end of the heat exchange tube 300 is connected to the water inlet channel 510, and the other end is connected to the water outlet channel 520. External cold water can enter the heat exchange tube 300 through the water inlet pipe 101 and the water inlet channel 510 for heat exchange, and then flow out through the water outlet channel 520 and the water outlet pipe 102 to supply hot water to users.

[0098] In addition, the sewage chamber 530 is designed to discharge sewage or impurities that may accumulate inside the water heater. The sewage chamber 530 directly connects the liquid storage space 110 with the outside. The user can open the sewage valve to discharge the sewage inside the water heater tank 100 to keep the inside of the water heater clean and hygienic.

[0099] In this embodiment, the water inlet channel 510, the water outlet channel 520 and the sewage chamber 530 are formed on the same side panel 130, that is, possible water leakage points are set on the same side panel 130, making maintenance and inspection more convenient and efficient.

[0100] First, by designing the water inlet channel 510, the water outlet channel 520 and the sewage chamber 530 on the same side panel 130, the pipe connection inside the water heater becomes simpler, reducing the intersection and overlap between the pipes. Secondly, the possible leakage points are concentrated on the same side panel 130. In this way, when the water heater has a leakage problem, the user can quickly locate and solve the problem. This design avoids the difficulty of finding and repairing the leakage points scattered in different locations, improves maintenance efficiency, and reduces maintenance costs.

[0101] According to one embodiment of the present invention, referring to Figure 8 and Fig. 9As shown, the water outlet C of the water inlet channel 510 is arranged at the bottom of the side panel 130; the water inlet A of the water outlet channel 520 is arranged at the top of the side panel 130, and the water outlet B of the water outlet channel 520 is arranged below the electronic control component 400; the water inlet D of the sewage chamber 530 is arranged at the bottom of the side panel 130.

[0102] In an optional embodiment, the water outlet B of the water outlet channel 520 is disposed below the electric control component 400, so that the water and electricity of the electric control component 400 can be separated, which can greatly reduce the risk of electric shock caused by leakage. Even if leakage occurs inside the water heater, since the water outlet B is located below the electric control component 400 and there is a sufficient isolation distance between the two, there is no direct contact between water and electricity, thereby ensuring the safety of the user.

[0103] In another optional embodiment, the water outlet C of the water inlet channel 510 is arranged at the bottom of the side panel 130, that is, the water inlet end of the heat exchange tube 300 is arranged at the bottom of the side panel 130, so that the cold water can first enter the bottom area of ​​the liquid storage space 110 for heat exchange, so that the cold water in the heat exchange tube 300 can fully exchange heat and improve the heat exchange efficiency.

[0104] In another optional embodiment, the water inlet D of the sewage chamber 530 is arranged at the bottom of the side panel 130, which can ensure that the sewage and impurities at the bottom of the water heater are completely discharged. By discharging sewage from the bottom, the scale, sediment and other impurities inside the water heater can be more effectively removed, reducing the corrosion and damage to the internal structure of the inner tank 100.

[0105] In another optional embodiment, the water inlet A of the water outlet channel 520 is arranged at the top of the side panel 130, that is, the outlet end of the heat exchange tube 300 is arranged at the top of the liquid storage space 110. Since hot water usually floats and cold water sinks, thermal stratification will be formed in the liquid storage space 110. Setting the water inlet of the water outlet channel 520 at the top can ensure that the hot water at the top of the liquid storage space 110 is also fully heat exchanged, thereby improving the heat exchange efficiency and heat exchange effect.

[0106] According to one embodiment of the present invention, referring to Figure 2 , Figure 8 and Fig. 9 As shown, the water inlet channel 510 includes a first water inlet section 511 and a second water inlet section 512. The first water inlet section 511 is connected to the water inlet pipe 101, and the second water inlet section 512 is connected to the first water inlet section 511 and the heat exchange tube 300. An installation portion 501 for installing the expansion component 600 is provided at the connection between the first water inlet section 511 and the second water inlet section 512.

[0107] It can be understood that in this embodiment, by setting the first water inlet section 511 and the second water inlet section 512, the water inlet position can be changed, and the positions of the heat exchange tube 300, the water inlet pipe 101 and the expansion module can be reasonably arranged. The water inlet pipe 101 and the expansion module can be installed on the side of the side panel 130 away from the liquid storage space 110, providing installation space for the layout of the water inlet position, the water inlet pipe 101 and the expansion module, providing greater flexibility and convenience.

[0108] Since the first water inlet section 511 and the second water inlet section 512 are integrally formed on the side panel 130, in order to achieve a reasonable position layout of the water inlet pipe 101 and the expansion module on the side panel 130, there is no need to design complex pipelines outside the inner tank 100 to connect the water inlet pipe 101 and the expansion module, which greatly reduces the number and length of external connecting pipes, thereby reducing both the volume and the leakage points of the water heater.

[0109] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, the water channel assembly 500 further includes a water replenishment channel 540 , which is communicated with the sewage discharge chamber 530 to supply water to the liquid storage space 110 .

[0110] It can be understood that in this embodiment, the water channel assembly 500 also includes a water replenishment channel 540, which is integrally formed with the side panel 130. When the amount of water in the water heater decreases due to evaporation, leakage or other reasons during use, the water replenishment channel 540 can replenish water to the liquid storage space 110 to maintain a certain amount of water in the inner tank 100 of the water heater.

[0111] In this embodiment, fresh water from the outside enters the heat exchange tube 300 from the water inlet pipe 101 and exchanges heat with the heated liquid in the liquid storage space 110. The high-temperature water after heat exchange flows out from the outlet end of the heat exchange tube 300 and is provided to the user through the water outlet pipe 102. The user's water is obtained after heat exchange with the liquid in the liquid storage space 110 through the heat exchange tube 300. The user's water does not contact the components (heating component, valve body, etc.) in the liquid storage space 110 of the inner tank 100, thereby effectively ensuring the water quality of the user's water. At the same time, impurities or pollutants that may exist in the user's water will not cause pollution to the components in the liquid storage space 110 (such as scale formation on the surface of the heating component), thereby effectively improving the service life of the water heater.

[0112] During the heating process of the liquid in the liquid storage space 110, part of the liquid will vaporize to form steam and be discharged from the liquid storage space 110 (to ensure the pressure in the liquid storage space 110 is stable). Accordingly, the liquid content in the liquid storage space 110 is reduced. The liquid in the liquid storage space 110 is replenished by setting a liquid replenishment channel to ensure the heat exchange efficiency between the liquid and the water in the heat exchange tube 300; and the water replenishment channel 540 is integrally formed on the side panel 130, does not occupy additional space, and does not require separate component installation, which effectively reduces the production and installation costs of the water heater; and the water replenishment channel 540 is connected to the liquid storage space 110 through the sewage cavity 530, reduces the number of openings on the side panel 130, and improves the structural strength of the side panel 130.

[0113] In this embodiment, the liquid in the liquid storage space 110 can be the same water source as the heat exchange tube 300, or can be oil, phase change energy storage material, etc.

[0114] According to one embodiment of the present invention, referring to Figure 5 and Fig. 9 The control valve 800 includes: a cold water inlet connected to the water inlet pipe 101; a hot water inlet connected to the outlet end of the heat exchange tube 300; a first water outlet connected to the water outlet pipe 102 to provide water for users; and a second water outlet connected to the water replenishment channel 540 to supply water to the liquid storage space 110.

[0115] It can be understood that in the present embodiment, part of the low-temperature water in the water inlet pipe 101 enters the liquid storage space 110 and exchanges heat with the water in the liquid storage space 110 to form high-temperature water. The high-temperature water enters the control valve 800 and mixes with the remaining low-temperature water in the water inlet pipe 101 in a certain proportion to form constant temperature water required by the user. Part of the constant temperature water is discharged from the first water outlet for user use; and the other part of the constant temperature water flows back from the second water outlet to the liquid replenishment channel to replenish the water in the liquid outlet space.

[0116] In this embodiment, by setting the control valve 800, the user can change the outlet water temperature of the constant temperature water according to his own needs. At the same time, the control valve 800 can also be used as a water replenishment valve, thereby reducing the number of components during the installation of the water heater, improving the installation efficiency and reducing the volume of the water heater; and the water flowing back from the control valve 800 to the water replenishment channel 540 has a certain temperature, thereby reducing the temperature fluctuation of the water in the liquid storage space 110 and improving the heat exchange efficiency inside the water heater.

[0117] In this embodiment, high temperature water, low temperature water, and constant temperature water are relative concepts, and it only needs to satisfy that the temperature of the high temperature water is greater than the temperature of the constant temperature water and greater than the temperature of the low temperature water.

[0118] In this embodiment, the control valve 800 may be a manual thermostatic valve or an electronic thermostatic valve.

[0119] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, the water circuit assembly 500 includes a transition section 550, and the heat exchange tube 300 includes a first heat exchange section 310 and a second heat exchange section 320, 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, and the first heat exchange section 310 and the second heat exchange section 320 are connected through the transition section 550.

[0120] It can be understood that in this embodiment, 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.

[0121] 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.

[0122] 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.

[0123] The transition section 550 connects the first heat exchange section 310 and the second heat exchange section 320. Through the design of the transition section 550, the first heat exchange section 310 and the second heat exchange section 320 can be designed separately. And the transition section 550 can ensure that the water flow can smoothly transition from the first heat exchange section 310 to the second heat exchange section 320 to a certain extent, avoiding excessive resistance or eddy current generated by the water flow during the transition process.

[0124] According to one embodiment of the present invention, referring to Figure 2As shown, the heater 200 includes a plurality of heating tubes, which 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.

[0125] It can be understood that in this embodiment, the spiral first heat exchange section 310 can be tightly wound around the outside of the annular heating tube along the length direction of the heating tube. 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. Heat can be transferred from the heating tube and 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.

[0126] And through the spiral winding design of the first heat exchange section 310, the water flow is guided to flow around the heating tube, 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.

[0127] In addition, the spiral winding design of the first heat exchange section 310 cooperates with the heating tube 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.

[0128] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, the side panel 130 is integrally formed with an exhaust channel 120, and the exhaust channel 120 connects the space above the liquid level in the liquid storage space 110 with the outside.

[0129] In the process of heating the liquid in the water tank of a conventional water heater, the liquid in the water tank will expand, thereby applying pressure to the water tank. For the safety performance 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 to adopt a pressure-bearing structure design. A square or other shape can be adopted, which allows the box body in this embodiment to be designed to be smaller in size, reducing the space occupied by the water heater.

[0130] An embodiment of a second aspect of the utility model provides a water heater, comprising a water tank of the water heater according to any one of the above embodiments.

[0131] It can be understood that if the water tank of the water heater has the beneficial effects of the above embodiments, then the water heater will correspondingly have the beneficial effects of the above embodiments. Its specific implementation method can refer to the above embodiments, and this application will not go into details.

[0132] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not deviate from the spirit and scope of the technical solutions of the present invention, and should be included in the protection scope of the present invention.
