[0036] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The following is combined with Figure 1-4 The water heater according to the embodiment of the present invention is described.

[0038] The water heater of the embodiment of the present utility model comprises a housing 1, a heating element 5, an exhaust pipe 6, a heat exchange element 7, a delivery box 2 and a filter bag.

[0039] A liquid storage chamber 11 is provided in the housing 1, and the housing 1 is used to store a heat exchange medium. The heating element 5 is used to heat the heat exchange medium in the liquid storage chamber 11. The exhaust pipe 6 connects the space above the liquid level in the liquid storage chamber 11 with the outside world. At least part of the heat exchange element 7 is arranged in the liquid storage chamber 11 to enable heat exchange between the heat exchange medium in the liquid storage chamber 11 and the dynamic water flowing in the heat exchange element 7. A accommodating chamber 21 is provided in the delivery box 2, and the accommodating chamber 21 is connected to the liquid storage chamber 11. A filter bag is provided in the accommodating chamber 21, and a plurality of mesh holes are provided on the filter bag. The filter bag is filled with a corrosion inhibitor that can be dissolved in water.

[0040] The liquid storage chamber 11 can be connected to the outside world through the exhaust pipe 6, ensuring that the pressure in the liquid storage chamber 11 is close to that of the outside world, and no additional pressure is generated on the inner wall of the liquid storage chamber 11. Therefore, the liquid storage chamber 11 does not need to be set to a pressure-bearing shape (such as a barrel shape), so that the shape of the liquid storage chamber 11 can be adaptively designed according to the installation position of the water heater, thereby improving space utilization.

[0041] The heat exchange medium in the liquid storage chamber 11 is static and always stays in the liquid storage chamber 11 and cannot flow out for user use. The heating element 5 and the heat exchange element 7 are both arranged in the liquid storage chamber 11. The heating element 5 heats the heat exchange medium in the liquid storage chamber 11. The heat exchange element 7 has a heat exchange channel. The box body 1 is provided with a water inlet and a water outlet. The two ends of the heat exchange channel are respectively connected to the water inlet and the water outlet. After the dynamic water in the external water pipe enters the heat exchange channel through the water inlet, it is heated by the heat exchange medium in the liquid storage chamber 11 and flows out from the water outlet for user use. Optionally, the heat exchange channel is S-shaped. A portion of the heat exchange element 7 is arranged in the liquid storage chamber 11 or the heat exchange element 7 is entirely located in the liquid storage chamber 11.

[0042] Optionally, the heat exchange medium is water.

[0043] In this embodiment, the delivery box 2 is connected to the box body 1, and the water in the liquid storage chamber 11 can enter the accommodating chamber 21 and contact the filter bag. Then the water in the accommodating chamber 21 contacts the anti-corrosion and corrosion inhibitor through the mesh on the filter bag. The anti-corrosion and corrosion inhibitor slowly dissolves after being soaked in water, and is then dispersed in the liquid storage chamber 11 and adheres to the inner wall of the box body 1 to form a protective film, thereby preventing the inner wall of the box body 1 from rusting.

[0044] The corrosion inhibitor in the filter bag is in granular form. This makes it easier to add the corrosion inhibitor and, during regular maintenance, the amount of corrosion inhibitor to be added can be adjusted based on the consumption of the corrosion inhibitor, thus avoiding overuse of the corrosion inhibitor and saving costs.

[0045] It should be noted that the position of the housing 1 in the liquid storage chamber 11 is not specifically limited in this embodiment, as long as the water in the liquid storage chamber 11 can enter the accommodating chamber 21 and contact the corrosion inhibitor in the filter bag. For example, the housing 1 is disposed on the bottom wall or side wall of the liquid storage chamber 11.

[0046] It is understandable that anti-corrosion inhibitors are a type of chemical raw material commonly used in industry. For example, anti-corrosion inhibitors include phosphates or nitrites, etc., which will not be described in detail here.

[0047] In the related art, the anti-corrosion and corrosion inhibitor particles are directly placed in the tank, which makes it difficult to observe the consumption of the anti-corrosion and corrosion inhibitor. According to the water heater of the embodiment of the utility model, on the one hand, the anti-corrosion and corrosion inhibitor is filled in the filter bag, and the consumption of the anti-corrosion and corrosion inhibitor can be intuitively understood by regularly checking the size change of the filter bag. The amount of anti-corrosion and corrosion inhibitor to be added can be controlled according to the consumption of the anti-corrosion and corrosion inhibitor, thereby effectively controlling the consumption of the agent, avoiding waste caused by excessive addition, and also reducing the risk of corrosion caused by insufficient agent.

[0048] On the other hand, in this embodiment, an anticorrosion inhibitor is placed in the liquid storage chamber 11, allowing it to contact the water in the liquid storage chamber 11 and gradually dissolve. When the anticorrosion inhibitor dissolves in water, the anticorrosion inhibitor released forms a protective film on the inner wall surface of the liquid storage chamber 11, thereby playing an anti-corrosion role, thereby preventing the inner wall of the housing 1 from rusting, improving the stability of the electric water heater, and forming a protective film layer without plating an anticorrosion inhibitor layer on the inner wall of the chamber, thereby simplifying the production process.

[0049] In addition, the water heater of the embodiment of the utility model directly places the anti-corrosion inhibitor in the liquid storage chamber 11. Compared with setting a magnesium rod in the liquid storage chamber 11, the anti-corrosion inhibitor has a better anti-corrosion effect, a longer service life, and a lower replacement frequency, and even does not need to be replaced during the use period.

[0050] In some embodiments, the delivery box 2 includes a shell 22 , which defines a receiving chamber 21 . The shell 22 is provided with a plurality of through holes 221 , and the receiving chamber 21 is connected to the liquid storage chamber 11 through the through holes 221 .

[0051] like Figures 1 to 4 As shown, the inner wall of the housing 22 forms a receiving chamber 21. The shape of the receiving chamber 21 can be designed based on actual needs and is not specifically limited in this embodiment. For example, the receiving chamber 21 can be rectangular or cylindrical. Multiple through-holes 221 are provided on the side of the housing 22 that contacts the liquid storage chamber 11. The diameter of the through-holes 221 is smaller than the size of the filter bag (the length and width of the filter bag). Water flows back and forth between the liquid storage chamber 11 and the delivery box 2 through the through-holes 221.

[0052] According to the water heater of the embodiment of the present utility model, the liquid storage chamber 11 and the accommodating chamber 21 can be connected by providing a through hole 221 on the shell 22, which has a simple structure and is easy to process.

[0053] In some embodiments, the delivery box 2 further includes a sealing cover 23 , which is detachably connected to the shell 22 . The delivery box 2 further includes a sealing ring 24 , which is disposed between the sealing cover 23 and the shell 22 .

[0054] like Figures 1 to 4 As shown, a sealing cover 23 is provided at the opening of the housing 22. The sealing cover 23 is used to open or close the receiving chamber 21. When it is necessary to check the consumption of the medicine, the sealing cover 23 can be opened to check or replace the filter pack. The sealing cover 23 is then connected to the housing 22 to close the receiving chamber 21. A sealing ring 24 seals the gap between the sealing cover 23 and the housing 22, thereby preventing water in the receiving chamber 21 from flowing out through the gap and thus preventing leakage from the box 1.

[0055] Optionally, a connecting portion is provided on the housing 22, and a threaded hole is provided on the connecting portion, and the sealing cover 23 is connected to the threaded hole of the housing 22 by a bolt. Alternatively, the sealing cover 23 is connected to the housing 22 by a snap connection.

[0056] In some embodiments, the water heater further comprises a shell 3, and the tank 1 and the delivery box 2 are both arranged in the shell 3. Figure 1 and Figure 2 As shown, the housing 3 plays a role in protecting the box body 1 on the one hand and can be used as a decorative panel on the other hand. In addition, a control panel and other devices are also provided on the housing 3. The housing 3 defines a cavity, and the box body 1 and the delivery box 2 are both arranged in the cavity.

[0057] In some embodiments, the box body 1 includes a bottom plate 12 , a first opening 121 is defined on the bottom plate 12 , the shell 22 is located at the first opening 121 , and an outer peripheral wall of the shell 22 is sealed to the bottom plate 12 .

[0058] like Figure 1 and Figure 2 As shown, the bottom plate 12 of the housing 1 is disposed at the bottom of the liquid storage chamber 11. When the housing 1 is in a cubic shape, the bottom plate 12 is a flat plate. When the housing 1 is in a cylindrical shape, the bottom plate 12 is an arc-shaped plate at the bottom of the housing 1. A through hole 221 is provided at the top of the shell 22, through which water in the liquid storage chamber 11 can enter the accommodating chamber 21. The outer peripheral wall of the shell 22 is adapted to the shape of the first opening 121, and the outer peripheral wall of the shell 22 is sealed to the wall surface at the first opening 121 to prevent water in the liquid storage chamber 11 from flowing out of the gap between the shell 22 and the bottom plate 12.

[0059] In the water heater of the embodiment of the present invention, the delivery box 2 is arranged at the bottom of the box body 1. As long as there is water in the liquid storage chamber 11, the anti-corrosion and corrosion inhibitor in the accommodating chamber 21 can be immersed in the water, thereby facilitating the dissolution of the anti-corrosion and corrosion inhibitor.

[0060] It is understood that the relative positions of the housing 22 and the base plate 12 can be arranged according to actual design requirements. For example, the entire housing 22 can be installed in the liquid storage chamber 11, the bottom of the housing 22 can be connected to the wall forming the first opening 121, and the sealing cover 23 can be substantially flush with the base plate 12. Alternatively, the entire housing 22 can be arranged at the bottom of the base plate 12, that is, the entire housing 22 can be installed outside the liquid storage chamber 11, and the top of the housing 22 can be connected to the wall forming the first opening 121, and the sealing cover 23 can be arranged below the base plate 12.

[0061] In some embodiments, the water heater further includes a decorative cover 4 . The housing 3 is provided with a second opening 31 corresponding to the first opening 121 . The decorative cover 4 is detachably provided at the second opening 31 .

[0062] When the delivery box 2 is arranged at the bottom of the box body 1, in order to facilitate the replacement of the preservative and corrosion inhibitor in the delivery box 2, a second opening 31 is provided on the outer shell 3, and the first opening 121 and the second opening 31 are arranged opposite to each other. In other words, the second opening 31 is arranged opposite to the delivery box 2, and the delivery box 2 can be seen by opening the decorative cover 4 at the second opening 31.

[0063] When it is necessary to add the anti-corrosion inhibitor, first drain all the water in the liquid storage chamber 11, then open the decorative cover 4, then open the sealing cover 23, then open the shell 22, and then check the remaining amount of the anti-corrosion inhibitor in the accommodating chamber 21.

[0064] The water heater of the embodiment of the present invention is provided with a decorative cover 4 , thereby facilitating the replacement of the anti-corrosion inhibitor in the delivery box 2 .

[0065] In some embodiments, as Figure 3 and Figure 4As shown, the outer shell 3 includes a maintenance side panel 32, and the box body 1 includes a first side panel 13, which is arranged close to the maintenance side panel 32. A third opening 131 is provided on the first side panel 13, and the shell 22 is provided at the third opening 131, and the outer peripheral wall of the shell 22 is sealed and connected to the first side panel 13.

[0066] In this embodiment, the housing 3 includes a bottom panel 12, a top panel, and multiple side panels. A maintenance panel 32 is provided on the side of the housing 3. Opening the maintenance panel 32 allows access to the cabinet 1. A first side panel 13 is provided on the side of the cabinet 1 adjacent to the maintenance panel 32. The first side panel 13 and the maintenance panel 32 are spaced apart.

[0067] The outer peripheral wall of the shell 22 is adapted to the shape of the third opening 131 , and the outer peripheral wall of the shell 22 is sealedly connected to the wall surface at the third opening 131 to prevent water in the liquid storage chamber 11 from flowing out from the gap between the shell 22 and the bottom plate 12 .

[0068] In the water heater of the embodiment of the present invention, the delivery box 2 is arranged on the side of the box body 1 and adjacent to the maintenance side panel 32 of the outer shell 3. The delivery box 2 can be seen by simply opening the maintenance side panel 32, and the condition of the anti-corrosion and corrosion inhibitor in the delivery box 2 can be checked, thereby facilitating the replacement of the anti-corrosion and corrosion inhibitor.

[0069] In some embodiments, the filter bag is a cloth filter bag, a plastic filter bag, or a metal filter bag.

[0070] Filter bags can be made of perforated fabric, plastic mesh, or metal mesh, such as wire mesh. Plastic mesh will not rot or rust after prolonged immersion in water. Metal filter bags (such as stainless steel) are durable and can withstand high temperatures and pressures, are not easily corroded, and are suitable for long-term, repeated use.

[0071] In some embodiments, a plurality of delivery boxes 2 are provided, and the plurality of delivery boxes 2 are arranged at intervals, and the accommodating cavity 21 of each delivery box 2 is communicated with the liquid storage cavity 11 .

[0072] Multiple delivery boxes 2 are arranged at intervals on the box body 1. For example, a delivery box 2 is provided at the bottom of the box body 1, and a delivery box 2 is also provided on the side panel of the box body 1. This makes it convenient to deliver filter bags from multiple positions to increase the concentration of the anti-corrosion and corrosion inhibitor, thereby improving the anti-corrosion and corrosion inhibition effect.

[0073] In some embodiments, the water heater further includes a temperature measuring element 8, which is disposed within the liquid storage chamber 11 to detect the temperature of the heat exchange medium within the liquid storage chamber 11. For example, the temperature measuring element 8 is mounted on the first side plate 13. This facilitates real-time monitoring of the temperature of the water within the liquid storage chamber 11 so that the water can be heated to a target temperature.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
