[0042] 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, the water tank of the water heater is provided with a circuit board for controlling the working parameters of the water heater. The circuit board 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.

[0043] The embodiments of the present utility model refer to Figure 1-Figure 5 As shown, a water tank of a water heater and a water heater are provided.

[0044] According to an embodiment of the present utility model, please refer to Figure 1 and Figure 2 According to the water tank of the water heater of the embodiment of the utility model, the water tank includes an inner tank 100, the inner tank 100 is formed with 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, and is used to heat the liquid storage space 110; an electric control component 400 is installed on the side panel 130; a heat exchange pipe 300 is arranged in the liquid storage space 110 to exchange heat with the liquid storage space 110; and an exhaust channel 120 connects the space above the liquid level in the liquid storage space 110 with the outside world.

[0045] 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.

[0046] 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.

[0047] The electric control component 400 can be connected to the heater 200 to control the heating parameters of the heater 200. The electric control component 400 is installed on the side panel 130. When the water tank leaks, the electric control component 400 is located on the side panel 130 instead of being directly immersed in the liquid, 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 water tank, the isolation design of the electric control component 400 can effectively avoid the occurrence of short circuits and ensure the safe operation of the water heater. The electric control component 400 is installed on the side panel 130. Compared with being installed on the bottom of the inner tank 100, the maintenance personnel can more conveniently approach and inspect the electric control component 400, reducing maintenance costs and time. When the water heater fails, the electric control component 400 is relatively fixed and easy to observe, so the problem can be located more quickly, improving maintenance efficiency.

[0048] In this embodiment, the electric control component 400 may include but is not limited to a circuit board, a control chip, a temperature sensor, etc. For example, the circuit board is the basis of the electric control component 400, on which various electronic components and control chips are installed; the control chip is the core of the electric control component 400, responsible for receiving user instructions, detecting parameters such as water temperature, and controlling the operation of the heater 200; the temperature sensor is used to monitor the water temperature in the liquid storage space 110 in real time and feed the data back to the control chip. The electric control component 400 is installed on the side panel 130 as an independent module, making the water heater design more modular and convenient for assembly and debugging.

[0049] Exemplarily, in combination with the accompanying drawings, taking the cubic inner liner 100 box 100 as an example, the side panels 130 of the inner liner 100 include a left side panel 130, a right side panel 130, a front side panel 130 and a rear side panel 130. In addition, the inner liner 100 also includes a top panel and a bottom panel. The electronic control component 400 can be installed on one of the left side panel 130, the right side panel 130, the front side panel 130 and the rear side panel 130. For example, in a specific embodiment, the electronic control component 400 is installed on the right side panel 130.

[0050] 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.

[0051] Specifically, the inner tank 100 can be provided with a water inlet pipe 510 and a water outlet pipe, one end of the heat exchange tube 300 is connected to the water inlet pipe 510, 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 510, and first flows through the first heat exchange section of the heat exchange tube 300. Since the first heat exchange section 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, 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.

[0052] 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.

[0053] It is understandable that in the process of heating the liquid in the water tank, a conventional water heater will cause the liquid in the water tank to 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 inner tank 100 to adopt a pressure-bearing structure design. A square or other shape can be adopted, which allows the inner tank 100 in this embodiment to be designed to be smaller in size, reducing the space occupied by the water heater.

[0054] 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, an electronic control component 400, a heat exchange tube 300 and an exhaust channel 120. 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, and is used to heat the liquid storage space 110; the electronic control component 400 is installed on the side panel 130; the heat exchange tube 300 is arranged in the liquid storage space 110 to exchange heat with the liquid storage space 110; the exhaust channel 120 connects the space above the liquid level in the liquid storage space 110 with the outside world. By installing the electronic control component 400 on the side panel 130 of the inner tank 100, when the water tank leaks, since the electronic control component 400 is located on the side panel 130 instead of at the bottom of the inner tank 100, the chance of direct contact between the electronic control component 400 and the leaking water is greatly reduced, thereby reducing the risk of electric leakage, reducing safety hazards, and improving the safety performance of the water heater.

[0055] Furthermore, the water tank of the water heater may also include a shell 700 , the shell 700 is formed with a receiving cavity, and the inner tank 100 and the electric control component 400 and other parts are all arranged in the receiving cavity of the shell 700 for protection.

[0056] According to the water tank of the water heater of the utility model, Figure 2 and Figure 3 As shown, the water tank of the water heater further includes a water circuit assembly 500 , the electric control component 400 is disposed in the top area of ​​the side panel 130 , the water circuit assembly 500 is mounted on the side panel 130 , and the water circuit assembly 500 is located below the electric control component 400 .

[0057] It is understandable that, in this embodiment, the electric control component 400 is arranged on the top of the side panel 130, and the water circuit assembly 500 is arranged 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 part fails, it will not affect the normal operation of the power board, thereby ensuring the overall stability and reliability of the water heater. Since the electric control component 400 is arranged above the water circuit assembly 500, it can effectively prevent the water circuit assembly 500 from leaking water without affecting the operation of the electric control component 400, avoiding the risk of leakage. This design greatly improves the safety of the water heater and reduces the risk of electric shock to users.

[0058] When the water circuit assembly 500 or the electric control component 400 needs to be inspected or maintained, since they are respectively located in different areas of the side panel 130, they can be inspected or maintained independently, which reduces the complexity of the inspection and maintenance and improves work efficiency.

[0059] According to the water tank of the water heater of the utility model, Figure 2 and Figure 3 As shown, the side panel 130 includes a front panel 131 facing the user side and a left end panel 132 and a right end panel 133 respectively connected to both sides of the front panel 131, and the electronic control component 400 is arranged on one of the left end panel 132 and the right end panel 133.

[0060] It is understandable that in the related art, the water circuit assembly 500 is also arranged at the bottom of the inner tank 100, which occupies a large space. In this embodiment, the electric control component 400 and the water circuit assembly 500 are installed on the same side panel 130 (left end panel 132 or right end panel 133), which can reduce the overall occupied space. This compact layout design not only optimizes the internal structure of the water heater, but also makes the overall size of the water heater more compact, so as to better adapt to various installation environments and space requirements.

[0061] The electric control component 400 is arranged on the left end plate 132 and the right end plate 133, which can reduce the thickness of the water heater in the front-to-back direction compared to the case where the electric control component 400 is arranged on the front panel 131. The front panel 131 is usually directly facing the user and may include user interaction elements such as a display screen and operation buttons, so its thickness usually needs to consider the user's operating convenience and visual experience. Moving the electric control component 400 to the left end plate 132 or the right end plate 133 on the side can free up space on the front panel 131, thereby allowing the design of a thinner front panel 131.

[0062] Since the electric control component 400 and the water circuit assembly 500 are installed on the same side panel 130, the installation process and the maintenance process become simpler and more direct, reducing the steps of the installer and the maintenance personnel moving back and forth and connecting between different components, thereby improving the installation efficiency and maintenance efficiency.

[0063] According to the water tank of the water heater of the embodiment of the utility model, the electric control component 400 and the water circuit assembly 500 are arranged side by side on the left end plate 132 or the right end plate 133, and the electric control component 400 is located on the side close to the front panel 131.

[0064] It is understandable that in this embodiment, the electric control component 400 and the water circuit assembly 500 are arranged side by side, which can also achieve water and electricity partition isolation, prevent direct contact between water and electricity, thereby avoiding possible electrical failures and safety hazards, and improve safety performance. The side-by-side layout makes the internal structure of the water heater more compact, which is conducive to reducing the volume and occupied space of the water heater. Since the electric control component 400 and the water circuit assembly 500 are arranged side by side and are independent of each other, maintenance and maintenance personnel can more conveniently operate these two parts separately. At the same time, this design can also improve the space utilization rate inside the water heater, and is convenient for installation in areas such as bathrooms and kitchens with limited space.

[0065] Furthermore, the electric control component 400 is arranged on a side close to the front panel 131, that is, the electric control component 400 is placed in the front half area of ​​the right end plate 133 of the inner tank 100, the water circuit assembly 500 is in the rear half area of ​​the right end plate 133 of the inner tank 100, and the power board is placed in the front half area close to the front, closer to the display panel. This layout makes the wiring between the power board and the display panel more convenient, reducing the potential safety hazards and costs caused by long-distance wiring. At the same time, short-distance wiring also helps to reduce signal attenuation and interference between connecting wires, improve the overall performance of the water heater, and because the wiring distance between the power board and the display panel is shortened, the required length of the connecting wire is also reduced accordingly. This not only reduces material costs, but also helps to reduce the complexity of wiring inside the water heater and improve the compactness of the overall structure.

[0066] The water channel is arranged in the rear half area on the right side of the inner tank 100, which can better realize the hidden water channel design. This design makes the appearance of the water heater more concise and beautiful, and also helps to protect the water channel from the influence of the external environment and prolong its service life.

[0067] The hidden water channel design is more in line with the pursuit of beauty and neatness in modern homes. By hiding the water channel part inside the water heater, the impact on the appearance can be reduced, making the water heater better integrated into the home environment.

[0068] To sum up, placing the power board and the water channel part in the front and rear half areas of the right end plate 133 of the inner tank 100 respectively not only realizes the water and electricity partition, but also improves the convenience of wiring, reduces material costs, and realizes a hidden water channel design, meeting the dual needs of beauty and practicality.

[0069] According to one embodiment of the present invention, referring to Figure 1 As shown, a housing 700 is also included, and a mounting cavity 710 is defined between the side panel 130 and the housing 700 , and the electric control component 400 is disposed in the mounting cavity 710 .

[0070] The installation cavity 710 provides a relatively closed and protected environment for the electric control component 400, which can prevent external factors (such as dust, moisture, impact, etc.) from damaging the electric control component 400. This helps to improve the service life and stability of the electric control component 400 and reduce the failure rate. In addition, by arranging the electric control component 400 in the installation cavity 710 between the side panel 130 and the housing 700, the design of the water heater tank is more compact and the use of the internal space is optimized. This can not only reduce the overall volume of the water heater, but also improve the utilization of the space, making it more suitable for installation in a limited space.

[0071] According to one embodiment of the present invention, referring to Figure 3 , Figure 4 and Figure 5 As shown, the water circuit assembly 500 includes a water inlet pipe 510, which is connected to the heat exchange tube 300, and a mounting portion 502 suitable for mounting the expansion module 600 is provided between the water inlet pipe 510 and the heat exchange tube 300. In some embodiments, the electric control component 400 is suitable for connecting to the expansion module 600 to control the operation of the expansion module 600.

[0072] The water inlet pipe 510 and the heat exchange pipe 300 are provided with a mounting portion 502, which can be a standardized interface or platform for installing various expansion modules 600. These expansion modules 600 can be selected according to user needs and application scenarios to enhance the function and performance of the waterway assembly 500.

[0073] The expansion module 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.

[0074] In an optional embodiment, reference Figure 3 , Figure 4 and Figure 5 As shown, the water circuit assembly 500 includes a water inlet pipe 510 and a water inlet section 501 connecting the water inlet pipe 510 and the heat exchange tube 300 , and the water inlet section 501 is provided with a mounting portion 502 suitable for mounting the expansion module 600 .

[0075] It can be understood that in this embodiment, the water inlet pipe 510 is the main part of the water circuit assembly 500, which is used to introduce cold water into the heat exchange tube 300 for heat exchange. The water inlet section 501 is the part connecting the water inlet pipe 510 and the heat exchange tube 300, and plays a role of transition and connection. The design of the water inlet section 501 needs to ensure that water can flow into the heat exchange tube 300 steadily and smoothly, and can withstand the pressure and temperature changes generated during system operation.

[0076] In some embodiments, the water inlet section 501 can be set on the side of the side panel 130 close to the liquid storage space 110. By setting the water inlet section 501, the water inlet position can be changed, and the positions of the water inlet pipe 510 and the expansion module 600 can be reasonably arranged without occupying the space outside the inner liner 100. The water inlet pipe 510 and the expansion module 600 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 and the water inlet pipe 510 and the expansion module 600, providing greater flexibility and convenience.

[0077] According to the water tank of the water heater of the utility model, Figure 2 and Figure 5 As shown, the water channel assembly 500 is installed at the middle or bottom of the side panel 130, and the water channel assembly 500 and the expansion module 600 are arranged side by side.

[0078] It is understandable that in this embodiment, the waterway assembly 500 and the expansion module 600 are arranged side by side, making the overall structure more compact. The side-by-side arrangement can make the structure inside the entire water heater more compact and improve space utilization. In addition, the waterway assembly 500 and the expansion module 600 are arranged side by side in the middle or bottom of the side panel 130, which can achieve centralized management of all related components. 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.

[0079] In this embodiment, the expansion module 600 is designed as an independent module, so that modular production of the water heater can be achieved. In this way, different expansion modules 600 can be flexibly adjusted according to user needs and market changes to meet the needs of different users.

[0080] According to the water tank of the water heater of the utility model, Figure 3 and Figure 5 As shown, the expansion module 600 includes at least one of a filtration module and a sterilization module.

[0081] In an optional embodiment, the expansion module 600 can be a filter module, which is arranged between the water inlet pipe 510 and the heat exchange tube 300 to filter out large particles of impurities in the water, such as mud, rust, etc., to protect the heating elements and pipes inside the water heater from damage, and at the same time improve the water quality of the outlet water.

[0082] The filtration module can adopt a variety of different filtration media and filtration technologies, such as PP cotton, activated carbon, ultrafiltration membrane, etc., which can be selected according to water quality and treatment requirements, and this embodiment does not make specific limitations.

[0083] In another optional embodiment, the expansion module 600 may be a sterilization module, which can kill bacteria, viruses and other microorganisms in water to ensure that the hot water used by users is safe and hygienic.

[0084] The type of sterilization module can be a UV sterilization module, which uses ultraviolet radiation (especially UVC band, wavelength between 200 nanometers and 280 nanometers) to destroy the nucleic acid structure of bacteria and viruses, prevent their replication and reproduction, and thus achieve the effect of sterilization. UV sterilization has the advantages of high efficiency, rapidity, and no chemical residues. In addition, the sterilization module can also use other technologies, such as ozone sterilization, high temperature sterilization, electrolyzed water sterilization, etc., which are not specifically limited in this embodiment.

[0085] According to the water tank of the water heater of the embodiment of the utility model, the filter module is arranged upstream of the sterilization module.

[0086] It can be understood that in this embodiment, a filtering module and a sterilization module can be simultaneously provided on the water inlet section 501, and the filtering module is located upstream of the sterilization module, that is, the water in the water inlet pipe 510 is first filtered by the filtering module and then sterilized by the sterilization module, and then enters the heat exchange tube 300 to exchange heat with the hot water in the liquid storage space 110.

[0087] The filtration module can remove large particles of impurities, suspended matter, sediment, etc. in the water, which may affect the working efficiency of the sterilization module (such as UV sterilizer). When the water is clear, ultraviolet rays can better penetrate the water body and kill bacteria and viruses, thereby improving the sterilization efficiency. Impurities in the water may cause wear or blockage on the components of the sterilization module, reducing its service life. After pretreatment by the filtration module, the amount of impurities entering the sterilization module can be greatly reduced, thereby extending the service life of the sterilization module. Therefore, filtering first and then sterilizing can ensure better sterilization effect.

[0088] According to the water tank of the water heater of the utility model, Figure 3 and Figure 5 As shown, the heater 200 is installed at the bottom of the side panel 130 , and the heater 200 is arranged between the expansion module 600 and the water inlet pipe 510 .

[0089] It can be understood that in the present embodiment, the heater 200 is installed at the bottom of the side panel 130. Since the heater 200 is located at the bottom, the liquid in the liquid storage space 110 will produce natural convection after heating, and the hotter liquid will rise while the colder liquid will sink, 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.

[0090] The heater 200 is also installed on the side panel 130, and all components can be installed on the same side panel 130, with an integrated setting and a reasonable layout, which reduces the occupied volume of the water heater and facilitates inspection and maintenance.

[0091] On the other hand, the heater 200 can be set in the middle of the bottom of the side panel 130 to ensure that the water at the bottom of the liquid storage space 110 is evenly heated. The expansion module 600 and the water inlet pipe 510 are located on both sides of the heater 200. The expansion module 600 can be set in the area of ​​the side panel 130 close to the front panel 131, and the water inlet pipe 510 can be set in the rear area of ​​the side panel 130 to hide the water inlet pipe 510.

[0092] In an optional embodiment, the exhaust channel 120 is integrally formed with the side panel 130. By integrally forming the exhaust channel 120 with the side panel 130, the volume of the liquid storage space 110 is not occupied. The storage capacity of the liquid is effectively increased while the external dimensions of the inner tank 100 remain unchanged, and the heat exchange efficiency between the liquid in the liquid storage space 110 and the water in the heat exchange tube 300 is improved. In addition, the high-temperature steam of the exhaust channel 120 is discharged from the side of the side panel 130, hidden from the user's line of sight to improve the aesthetics while ensuring that the steam will not spray toward the user, thereby avoiding scalding the user and improving the safety of the water heater.

[0093] 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.

[0094] 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.

[0095] 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.
