[0033] Water heaters are a common type of hot water equipment that is widely used in various places to provide people with the hot water they need in their daily lives. Water heaters can heat tap water to the required temperature to meet people's daily needs.

[0034] Rust is a common problem in water heaters, particularly in areas with hard or poor-quality water. Rust can severely impact water heater performance. For example, it can deposit on the heating element, hindering heat transfer and reducing heating efficiency. Furthermore, rust can accumulate in pipes, causing poor water flow and even blockages.

[0035] The following combination Figures 1 to 3 , the water channel assembly and the water heater 10 provided by the embodiment of the utility model are described in detail through specific embodiments and their application scenarios.

[0036] In the embodiment of the present utility model, referring to Figures 1 to 3 , providing a water heater 10, the water heater 10 includes a filter material and an energy storage box 100, the filter material contains an anti-corrosion and corrosion inhibitor soluble in a liquid; the energy storage box 100 has a liquid storage chamber 110 and a feeding port 120 connected to the liquid storage chamber 110, and the filter material can be fed into the liquid storage chamber 110 through the feeding port 120;

[0037] The energy storage box 100 is designed to be in communication with the atmosphere, the liquid storage chamber 110 can store static heating liquid, and the filter material is in contact with the static heating liquid.

[0038] In the embodiment of the present application, the filter material is placed in the liquid storage chamber 110. The initial placement method can be when the water heater 10 is assembled, by pre-placing the filter material in the liquid storage chamber 110. Alternatively, during subsequent use, when the filter material is exhausted or needs to be replaced, it can be added through the placement port 120 on the energy storage box 100. The provision of the placement port 120 makes it simple and quick to replace or replenish the anti-corrosion and corrosion-inhibiting filter material. The user can complete the operation without disassembling the main body of the water heater 10, greatly reducing maintenance costs and time.

[0039] It should be noted that the loading port 120 can be a loading port 120 specifically opened for loading filter materials, or it can be an installation port or opening of other parts of the energy storage box 100 where the water heater 10 is installed, such as the installation port or waste outlet of the liquid level probe 200.

[0040] The filter material is installed within the liquid storage chamber 110, and the liquid within the liquid storage chamber 110 can contact the filter material. There are no restrictions on the location of the filter material, as long as the filter material can be immersed in the liquid. When the filter material contacts the liquid, the agent slowly dissolves in the liquid, automatically forming a protective film on the inner surface of the liquid storage chamber 110, thereby providing corrosion protection.

[0041] The energy storage tank 100 primarily functions to store heat exchange medium. The liquid storage chamber 110 is used to store the heat exchange medium. A heating element is located within the liquid storage chamber 110, which heats the heat exchange medium to a set temperature and stores it within the liquid storage chamber 110. When a user requires hot water, the heat exchange medium exchanges heat with an external cold water pipeline, heating the water to the desired preset temperature. Furthermore, the energy storage tank 100 also has a certain degree of thermal insulation to reduce heat loss.

[0042] The present application provides a placement port 120 on the energy storage tank 100, placing an anti-corrosion and corrosion inhibitor in the water storage chamber, allowing it to contact the water in the water storage chamber and gradually dissolve. When the anti-corrosion and corrosion inhibitor dissolves in water, the anti-corrosion and corrosion inhibitor it releases forms a protective film on the inner wall surface of the water storage chamber, thereby playing an anti-corrosion role, thereby preventing the inner wall of the water storage tank from rusting and improving the stability of the water heater 10. In addition, the provision of the placement port 120 improves the convenience of placing the filter material. At the same time, it can ensure that after the filter material is placed into the heated liquid through the placement port 120, it is slowly released in the static heated liquid, increasing its service life and ensuring its use effect. The filter material will not flow to the user's shower head along the outlet pipe or block the outlet because the static liquid is only used for heat exchange and is not connected to the outlet pipe.

[0043] In some embodiments, the filter material is in the shape of a sphere or a cylinder.

[0044] It is understandable that the shape of the filter material is designed according to actual needs. For example, the filter material can be spherical, cylindrical or prism-shaped, such as a rectangular parallelepiped, a hexagonal prism, etc. The filter material can be a hollow body or a solid body. Among them, the spherical filter material is symmetrical in all directions, so the release of the anti-corrosion and corrosion inhibitor will be relatively uniform. It helps to ensure that the water in the liquid storage chamber 110 can be evenly protected by the anti-corrosion and corrosion inhibitor. The cylindrical filter material is easier to maintain stability after being put into use and is not prone to rolling or moving. This helps to ensure that the position of the filter material in the liquid storage chamber 110 is fixed, thereby improving the stability and reliability of the release of the agent.

[0045] It is understandable that anti-corrosion and corrosion inhibitors are a type of chemical raw material commonly used in industry. For example, anti-corrosion and corrosion inhibitors include phosphates or nitrites, etc., which will not be described in detail here.

[0046] In some embodiments, the maximum radius of the cross section of the filter material along its own axis is smaller than the radius of the injection port 120 .

[0047] It is understandable that since the maximum radius of the cross section of the filter material is smaller than the radius of the delivery port 120, the filter material can easily pass through the delivery port 120 into the liquid storage chamber 110 of the energy storage box 100. This avoids the problem of delivery difficulties or obstruction caused by the excessive size of the filter material, making the replacement and maintenance process of the filter material smoother and more efficient. If the size of the filter material is too large, it may cause friction or extrusion with the delivery port 120, causing damage or deformation of the sealing material around the delivery port 120. This may cause leakage of water or impurities, affecting the normal operation and service life of the water heater 10. By designing the maximum radius of the cross section of the filter material to be smaller than the radius of the delivery port 120, this risk can be minimized and the sealing and safety of the water heater 10 can be ensured.

[0048] Reference Figure 2 In some embodiments, the injection port 120 is a liquid level probe installation port 130 , and the liquid level probe installation port 130 is opened on the side wall of the energy storage box 100 .

[0049] It should be noted that the liquid level probe 200 is a sensor used to measure and monitor the liquid level in the energy storage tank 100. It is usually installed at a specific location on the side wall or bottom of the container to detect and provide feedback on the liquid level in real time, which is used to control liquid storage, prevent overflow, or monitor liquid consumption.

[0050] This embodiment combines the delivery port 120 with the liquid level probe mounting port 130, allowing the delivery port 120 to not only be used to deliver filter material into the energy storage box 100 but also to serve as an interface for mounting the liquid level probe 200. By combining these two functions, the need for additional holes or interfaces in the energy storage box 100 is avoided, saving valuable space and maintaining the box's neatness and integrity. This reduces the need for additional openings, simplifies the structure of the energy storage box 100, and mitigates potential sealing issues and safety hazards associated with unnecessary openings.

[0051] Reference Figure 1 In some embodiments, the injection port 120 is a sewage outlet 140 , and the sewage outlet 140 is located at the bottom of the energy storage box 100 .

[0052] It is understandable that the drain outlet 140 is provided at the bottom of the energy storage tank 100. It is mainly used to discharge the water in the liquid storage chamber 110 and is used during cleaning or maintenance. In this embodiment, the drain outlet 140 is also used as a delivery port 120 for the anti-corrosion and corrosion inhibitor filter material. The operator can drop the filter material containing the anti-corrosion and corrosion inhibitor into the liquid storage chamber 110 through the drain outlet 140 located at the bottom of the energy storage tank 100. The delivery process is simple and convenient, and there is no need to disassemble other components; at the same time, the use of the existing drain outlet 140 as the delivery port 120 reduces the need for additional openings, which not only saves space but also simplifies the structure of the water heater 10. The stability and maintenance convenience of the water heater 10 are improved.

[0053] In some embodiments, the injection port 120 is higher than the height of the liquid level probe, and when the injection port 120 is opened, it can connect the gas space inside the energy storage box 100 and the atmospheric space outside the energy storage box 100 .

[0054] It can be understood that in this embodiment, the delivery port 120 is a dedicated delivery port provided on the energy storage box 100. At the same time, it is ensured that the dedicated delivery port is higher than the liquid level to prevent water leakage, and the user can deliver the filter material through the delivery port.

[0055] Reference Figure 1In some embodiments, the water heater 10 further includes an exhaust and sewage plug 300 , which is detachably connected to the sewage outlet 140 and sealed.

[0056] It will be appreciated that the exhaust and sewage plug 300 is located at the drain port 140 at the bottom of the energy storage box 100. It is used to seal the drain port 140 to prevent leakage of water or other substances. The plug can be connected to or disconnected from the drain port 140 by tightening or loosening. The operator can remove the exhaust and sewage plug 300 to place the filter material into the liquid storage chamber 110.

[0057] The drain port 140 can be used to drain water from the liquid storage chamber 110 and also to insert filter material. The detachable design of the exhaust and drain plug 300 makes inserting filter material easier. The operator can easily remove the exhaust and drain plug 300 to add or replace filter material.

[0058] Reference Figure 1 In some embodiments, the water heater 10 further includes an exhaust pipe 400, an air inlet end 410 of the exhaust pipe 400 is disposed in the liquid storage chamber 110 and extends to the top of the liquid storage chamber 110, and an air outlet end of the exhaust pipe 400 is connected to the exhaust and sewage plug 300, and the exhaust pipe 400 is suitable for discharging the gas in the liquid storage chamber 110.

[0059] It will be appreciated that the air inlet end 410 of the exhaust pipe 400 is disposed within the liquid storage chamber 110 and extends to the top of the liquid storage chamber 110 to ensure that gases (such as air, water vapor, etc.) accumulated within the liquid storage chamber 110 can smoothly rise into the exhaust pipe 400 and be discharged. As the water heater 10 operates for an extended period of time, the water temperature within the liquid storage chamber 110 will continue to rise, generating water vapor and other gases. These gases increase the pressure within the liquid storage chamber 110 and, if not promptly discharged, may damage the structure of the water heater 10. Promptly venting the gas through the exhaust pipe 400 effectively reduces the pressure within the liquid storage chamber 110, ensuring the safe and stable operation of the water heater 10. The air outlet end of the exhaust pipe 400 is connected to the exhaust and sewage plug 300 to ensure that the liquid storage chamber 110 is sealed under normal circumstances and is only opened when venting is required. The exhaust pipe 400 can help regulate the air pressure in the liquid storage chamber 110 , while the exhaust and sewage plug 300 facilitates the placement of filter materials, thereby improving the stability and maintenance convenience of the water heater 10 .

[0060] In some embodiments, the inlet 120 is a quick-plug interface, and the water heater 10 includes a quick-plug plug, which is suitable for sealing the quick-plug interface.

[0061] As can be appreciated, the quick-connect design makes adding filter material to the water heater 10 a very simple and quick operation. The user simply pours the desired material into the quick-connect interface and quickly seals the interface with a quick-connect plug to complete the entire addition process. This significantly saves the user time and effort, and improves ease of use.

[0062] In some embodiments, a quick socket is provided at the quick-plug interface, a bayonet is provided on the peripheral wall of the quick-plug, and a ring groove is provided on the outer side of the quick-plug plug corresponding to the bayonet. The water heater 10 also includes a snap-in component, which passes through the bayonet and is placed in the ring groove to limit the quick-plug plug to be connected to the quick-plug interface.

[0063] It is understandable that this embodiment can ensure a stable connection between the quick-plug plug and the quick socket through the cooperation of the bayonet and the ring groove, as well as the insertion of the snap-in piece. It can effectively prevent the quick-plug plug from accidentally falling off during use. The design of the quick-plug interface makes the installation and removal of the quick-plug plug very simple and quick. The user only needs to align the ring groove of the quick-plug plug with the bayonet of the quick socket, then gently push it in, and then use the snap-in piece to pass through the bayonet and place it in the ring groove to complete the installation. Similarly, when disassembling, just remove the snap-in piece from the ring groove and then gently pull out the quick-plug plug. This convenient operation method greatly improves the user experience.

[0064] Specifically, when the filter material needs to be added, the user can easily remove the quick-plug plug. Since the design of the quick-plug interface makes the disassembly and installation process simple and quick, the user can complete the maintenance work more easily, thereby improving the reliability and use efficiency of the water heater 10.

[0065] In some embodiments, the inlet 120 is provided with an internal thread, and the water heater 10 includes a threaded plug, and the outer wall surface of the threaded plug is provided with an external thread. The threaded plug is sealed at the inlet 120 by threaded cooperation between the external thread and the internal thread.

[0066] It is understood that in this embodiment, the tight fit between the internal and external threads ensures that the inlet 120 is well sealed when blocked, effectively preventing water or steam from leaking from the water heater 10 and preventing external impurities or air from entering the water heater 10, thereby maintaining clean and hygienic water quality.

[0067] The threaded fitting ensures a secure connection between the threaded plug and the inlet 120. Even if vibration or shock occurs during operation of the water heater 10, the threaded plug remains in a stable connection without becoming loose or falling off, which could cause safety hazards.

[0068] The threaded connection makes the installation and removal of the threaded plug relatively simple. Users simply screw the threaded plug into the delivery port 120 to seal the device. To deliver the substance, simply reverse the rotation to easily remove the threaded plug. This convenient operation enhances the user experience.

[0069] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
