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

[0056] Combination Figure 1As shown, the water tank of the water heater according to the embodiment of the first aspect of the utility model includes a box body 10, a heat exchanger 20, a mounting bracket 80 and an anti-corrosion substance; the box body 10 is provided with a liquid storage space 11, and the space above the liquid level in the liquid storage space 11 is connected to the outside; the heat exchanger 20 is installed in the box body 10, and the heat exchanger 20 includes a heat exchange tube 21, and the heat exchange tube 21 is used to circulate water used by users, and the water in the heat exchange tube 21 and the liquid in the liquid storage space 11 are heat exchanged; the mounting bracket 80 is fixed to the inside of the box body 10, and a accommodating space 81 is formed in the mounting bracket 80, and the accommodating space 81 is connected to the liquid storage space 11 so that liquid can enter the accommodating space 81; the anti-corrosion substance is placed in the accommodating space 81.

[0057] According to the water tank of the water heater of the present invention, fresh water from the outside enters the heat exchanger 20 from the water inlet pipe 31, and exchanges heat with the heated liquid in the liquid storage space 11, and the high-temperature water after heat exchange flows out from the outlet end of the heat exchanger 20 for user use; during the heating process of the liquid in the liquid storage space 11, the liquid evaporates and forms steam, which gathers above the liquid surface in the liquid storage space 11, and the steam is discharged from the liquid storage space 11 to ensure that the pressure in the liquid storage space 11 is stable; and during the long-term use of the water tank of the water heater, the anti-corrosion material in the accommodating space 81 is corroded preferentially compared with other components in the water tank (metal components, inner wall of the box body 10, etc.), thereby ensuring the service life of the components in the box body 10.

[0058] It should be noted that in the related art, in order to prevent the inner tank of the water heater from being corroded, a magnesium rod is usually used as an anti-corrosion component. The magnesium rod, the inner tank and the liquid in the inner tank form a galvanic cell, and the inner tank is protected by the sacrificial anode cathode protection method. However, the installation of the magnesium rod requires an independent installation position to be opened in the inner tank, and it can only be used to install a rod-shaped magnesium rod, which has the problems of inconvenient installation and poor applicability.

[0059] According to the water tank of the water heater of the utility model, the anti-corrosion material is arranged in the accommodating space 81 of the mounting bracket 80, so that the anti-corrosion material is not limited to the rod-shaped form of the prior art, and its structural form can be more flexible (such as granular, powdery, etc.), and the structure of the corresponding mounting bracket 80 is adaptively adjusted, so that the components related to the anti-corrosion function in the water heater (mounting bracket 80, anti-corrosion material) can be used more flexibly, which is convenient for installation and effectively improves applicability.

[0060] Furthermore, the water used by the user is obtained by heat exchange with the liquid in the liquid storage space 11 through the heat exchanger 20, and does not contact the components (heater, valve body, etc.) in the liquid storage space 11 of the box 10, which effectively ensures the quality of the water used by the user. At the same time, the impurities or pollutants that may exist in the user's water will not cause pollution to the components in the liquid storage space 11 of the box 10 (such as the formation of scale on the surface of the heating component), which effectively improves the service life of the water heater. In the present application, the liquid storage space 11 is connected to the outside world to ensure that the pressure in the liquid storage space 11 is similar to that of the outside world, and no additional pressure is generated on the inner wall of the box 10. Therefore, the box 10 does not need to be set to a pressure-bearing shape (such as a barrel shape), and the shape of the box 10 can be adaptively adjusted according to the spatial arrangement requirements of the location of the water heater to improve space utilization.

[0061] According to one embodiment of the utility model, combined Figure 1 As shown, the mounting bracket 80 includes a sleeve 82, and a slow-release hole 83 is opened on the side wall of the sleeve 82. The liquid in the liquid storage space 11 enters the accommodating space 81 through the slow-release hole 83, ensuring full contact between the liquid and the anti-corrosion substance, and preventing any parts containing metal substances in the box body 10 from corroding and rusting; and the slow-release hole 83 can slow down the flow rate of the liquid, reduce the impact of the liquid on the anti-corrosion substance, prolong the contact time between the liquid and the anti-corrosion substance, and improve the anti-corrosion effect.

[0062] In the present embodiment, the sustained-release holes 83 are a plurality of circular holes evenly distributed on the side wall of the sleeve 82. It is understandable that at this time, the volume of the antiseptic material needs to be set larger than the diameter of the circular holes to ensure that the antiseptic material does not escape from the sustained-release holes 83. Of course, the structure of the sustained-release holes 83 can be changed based on the adaptability of the antiseptic materials of different shapes. When a long strip of antiseptic material is used, a strip-shaped sustained-release hole 83 can also be used.

[0063] According to an embodiment of the present invention, the sleeve 82 is sleeved to the exhaust pipe, the heat exchange pipe 21 or the temperature measuring pipe 73 of the box body 10. The sleeve 82 is directly sleeved on the existing tubular component in the box body 10, which has a simple structure and is easy to install, and the anti-corrosion material is closer to the corresponding tubular component, thereby enhancing the anti-corrosion effect of the component.

[0064] In this embodiment, combined with Figure 1 As shown, the sleeve 82 is sleeved on the temperature measuring tube 73, and the anti-corrosion material in the sleeve 82 is closest to the temperature measuring tube 73, which can ensure that the temperature measuring tube 73 does not corrode or rust. In addition, the sleeve 82 can be fixed by the temperature measuring tube 73, without the need for an additional fixing structure, which is simple and convenient.

[0065] Of course, the sleeve 82 can also be sleeved on tubular structures such as the exhaust pipe and the heat exchange tube 21, and the sleeve 82 can be connected to the tubular structure in a manner of sleeve-joining along the extending direction of the tubular structure (such as sleeve-joining on the temperature measuring tube 73). When the heat exchange tube 21 may not have an open end (both ends of the heat exchange tube 21 are connected to the box body 10), the sleeve 82 can also be in a form separated by a bisector passing through its axis to form the sleeve 82 on the heat exchange tube 21.

[0066] According to one embodiment of the utility model, combined Figure 1 and Figure 2 As shown, the heat exchange tube 21 includes a spiral heat exchange tube 211 and a heat exchange coil 212; the spiral heat exchange tube 211 is wound around the heater in the box body 10 and is located at the lower part of the liquid storage space 11; the heat exchange coil 212 is located at the upper part of the liquid storage space 11 and is sequentially connected with the spiral heat exchange tube 211; in this embodiment, the spiral heat exchange tube 211 makes full use of the space around the heater to perform preliminary heat exchange on the water in the heat exchanger 20, and then flows to the heat exchange coil 212 to further exchange heat with the liquid in the upper part of the liquid storage space 11, thereby extending the heat exchange area of ​​the heat exchanger 20 and improving the heat exchange effect of the water heater.

[0067] In this embodiment, combined with Figure 7 As shown, the heat exchanger 20 also includes a protective cover 22 and a mounting plate 23; the protective cover 22 is fixed to the box body 10 and covers the spiral heat exchange tube 211 (for ease of display, Figure 2 The top of the protective cover 22 is hidden in the box body 10, which is used to isolate the box body 10 and the spiral heat exchange tube 211; the mounting plate 23 is fixed to the box body 10, which is used to fix the heat exchange coil 212; the spiral heat exchange tube 211 or the heat exchange coil 212 is stably installed; and the mounting bracket 80 is set on the protective cover 22 or the mounting plate 23. The anti-corrosion material is close to the heat exchange tube 21, which effectively ensures that the heat exchange tube 21 is not corroded or rusted.

[0068] In this embodiment, two mounting plates 23 are located at both ends of the heat exchange coil 212 and are connected by a connecting rod. The mounting bracket 80 can be set on the mounting plate 23 at the end or on the connecting rod.

[0069] According to one embodiment of the utility model, combined Figures 2 to 5 As shown, the mounting bracket 80 is disposed on the protective cover 22, and the mounting bracket 80 includes a baffle 801 and a top plate 803 that are relatively disposed, and the ends of the baffles 801 are connected by reinforcing ribs 802 to form a receiving space 81 between the baffles 801; the top plate 803 can be detachably mounted on the baffle 801.

[0070] In this embodiment, a receiving space 81 is formed by relatively arranged baffles 801, two adjacent reinforcing ribs 802, a top plate 803 and the bottom of the protective cover 22, thereby effectively utilizing the original structure of the protective cover 22 (baffles 801, reinforcing ribs 802, etc.). The user only needs to put the anti-corrosion material into the receiving space 81 and cover it with the top plate 803, thereby effectively simplifying the assembly process.

[0071] In this embodiment, a mounting bracket 80 is provided on the protective cover 22. It can be understood that when the bottom of the protective cover 22 has a plurality of reinforcing ribs 802, each group of adjacent reinforcing ribs 802 can serve as a part of the mounting bracket 80, that is, a plurality of accommodating spaces 81 to be used can be pre-set on the protective cover 22. The user can selectively cover a portion of the reinforcing ribs 802 with a top plate 803 to form an accommodating space 81 according to the actual amount of preservatives required by the water heater.

[0072] In other embodiments, the mounting bracket 80 may also be an independent box-shaped structure, and then fixedly mounted to the protective cover 22 , so as to facilitate pre-loading of the anti-corrosion material in the mounting bracket 80 .

[0073] According to one embodiment of the utility model, combined Figures 3 to 6 As shown, one of the baffle plate 801 and the top plate 803 is provided with a buckle 741, and the other is provided with a slot 742 that cooperates with the buckle 741. The buckle 741 and the slot 742 cooperate to achieve a quick connection.

[0074] In this embodiment, the buckle 741 is arranged on the top plate 803, and the position of the buckle 741 is offset from the edge of the top plate 803 to the center by a certain distance. It can be understood that the offset distance ensures that a flat fitting surface is formed at the edge of the top plate 803, which is used to fit with the baffle 801 and the reinforcing rib 802, effectively ensuring a tight fit between the top plate 803 and the baffle 801 or the reinforcing rib 802.

[0075] In this embodiment, two buckles 741 are relatively arranged on both sides of the top plate 803. Of course, the number of buckles 741 can be adaptively adjusted according to the length or width of the top plate 803 to ensure the connection effect between the top plate 803 and the baffle 801.

[0076] According to one embodiment of the utility model, combined Figure 1 and Figure 8As shown, as shown (for the convenience of display in Figure 1, part of the roto-molded main body 191 is hidden, and only part of the roto-molded main body 191 on the opposite side of the non-roto-molded end plate 192 is retained), the box 10 includes a roto-molded main body 191 and a non-roto-molded end plate 192, the roto-molded main body 191 and the non-roto-molded end plate 192 are fixedly connected to enclose a liquid storage space 11, wherein the non-roto-molded end plate 192 can be made of metal, which is easier to open mounting holes for components or to open threads, bayonet and other structures for connection than the roto-molded main body; and the roto-molded main body 191 does not have metal components or components, so that the liquid in the liquid storage space 11 will not cause corrosion to the roto-molded main body 191, thereby effectively improving the service life of the box 10; through the splicing form of the roto-molded main body 191 and the non-roto-molded end plate 192, it not only satisfies the convenience of installing components on the box 10 but also effectively improves the anti-corrosion effect of the box 10.

[0077] Furthermore, the mounting bracket 80 is fixed to the non-roto-molded end plate 192 , so that the anti-corrosion material is closer to the non-roto-molded end plate 192 which is susceptible to corrosion, thereby specifically improving the service life of the non-roto-molded end plate 192 .

[0078] In this embodiment, the non-roto-molded end plate 192 is disposed on the side of the box 10, and the corresponding components outside the box 10 are also connected to the side of the box 10, so that at least some components are hidden from the user's field of vision (the user is usually located directly in front of the box 10), thereby improving the aesthetics of the water heater. Of course, the non-roto-molded end plate 192 can also be disposed at the bottom, top, etc. of the box 10, and adjusted according to the actual installation position requirements of the box 10.

[0079] According to an embodiment of the present invention, the fixed end of the mounting bracket 80 is threadedly connected to the non-roto-molded end plate 192, and the fixed end of the mounting bracket 80 at least partially passes through the non-roto-molded end plate 192 to the outside of the box 10, so as to disassemble and assemble the mounting bracket 80 from the outside of the box 10. The user only needs to drain the liquid in the box 10, unscrew the mounting bracket 80 from the thread and detach it from the non-roto-molded end plate 192, so as to achieve a quick replacement effect of the mounting bracket 80.

[0080] Of course, the mounting bracket 80 and the non-roto-molded end plate 192 may also be connected by magnetic attraction, snap-on connection, etc., to ensure a stable connection while ensuring a sealing effect.

[0081] According to one embodiment of the utility model, combined Figure 1 As shown, the water tank of the water heater includes a water circuit assembly 30 and a circuit board (not shown), and both the water circuit assembly 30 and the circuit board are installed on the non-roto-molded end plate 192. The water circuit assembly 30 includes a water inlet pipe 31 and a water outlet pipe 32, and both the water inlet pipe 31 and the water outlet pipe 32 are connected to the heat exchange tube 21.

[0082] In this embodiment, the water inlet pipe 31 and the water outlet pipe 32 can be pre-installed to form the water channel assembly 30 and then installed to the non-roto-molded end plate 192 to improve installation efficiency.

[0083] In this embodiment, the circuit board is used to control the operation of components on the water circuit assembly 30, such as a control valve, a pressure relief valve, etc.

[0084] In this embodiment, combined with Figure 1 As shown, a water circuit assembly 30 is installed on the non-roto-molded end plate 192, and the water circuit assembly 30 is located in the lower area of ​​the non-roto-molded end plate 192. The space reserved in the upper area of ​​the non-roto-molded end plate 192 can be used to install a circuit board (not shown in the figure) to prevent the water circuit assembly 30 from leaking and damaging the circuit board. Of course, the positional relationship between the water circuit assembly 30 and the circuit board can be adaptively adjusted, such as setting the water circuit assembly 30 on the rear side of the non-roto-molded end plate 192 and the circuit board on the front side of the non-roto-molded end plate 192, so that the user can observe the parameters of the various components of the water heater displayed on the display on the circuit board.

[0085] In one embodiment, the antiseptic material is antiseptic particles contained in the containing space 81, so as to increase the contact area between the antiseptic material as a whole and the liquid in the liquid storage space 11, thereby improving the antiseptic effect.
