Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a water outlet valve and a water circuit system for a wall-hung boiler. Background Technology

[0002] In the sanitary ware and heating industry, the water outlet valve is a key component for controlling and regulating water flow, and its structural design directly affects the safety, stability, and service life of the system. Currently, most water outlet valves on the market adopt an injection-molded integrated structure for their sanitary ware and heating water outlet connectors. This structure integrates the plastic valve body and metal connectors into one piece through injection molding, which has advantages such as convenient molding and lower cost in manufacturing process.

[0003] However, during the actual operation of a wall-hung boiler system, static electricity is easily generated when water flows through the pipes due to friction between water molecules and between water molecules and the inner wall of the pipes. In existing systems using injection-molded integrated outlet valves, the plastic valve body, acting as an insulating material, prevents the water from contacting the metal connectors, thus preventing the static electricity generated in the water flow from being effectively released to the outside, causing it to accumulate continuously within the system. With this continuous accumulation of static electricity, on the one hand, the high static voltage may trigger an electric spark, which could easily cause a safety accident near the wall-hung boiler water system in flammable or explosive environments such as those containing gas, posing a serious threat to the life and property of users; on the other hand, the accumulated static electricity can interfere with or even damage sensitive electronic components and sensors within the wall-hung boiler system, affecting the normal operation of the system, reducing the lifespan of the equipment, and increasing maintenance costs and user inconvenience.

[0004] Therefore, there is an urgent need to propose a water outlet valve and a water circuit system for wall-hung boilers to solve the above problems. Utility Model Content

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] like Figures 1-3 As shown, this embodiment provides a wall-hung boiler water system, which includes a boiler shell and a combustion chamber 200, a heat exchange structure 300, an inlet valve 400, and an outlet valve 100 installed inside the boiler shell. The combustion chamber 200 can heat the water inside it; the heat exchange structure 300 includes a heat exchange channel 310 and a water supply channel 320 that cooperate in heat exchange; the inlet valve 400 can supply water to the combustion chamber 200 and the water supply channel 320; the outlet valve 100 includes a valve body 1, which has an inlet 14, a first flow channel 13, and a second flow channel 15. Heating passage 16 and bathroom passage 17; water inlet 14 is connected to water outlet 201 of combustion chamber 200, and water inlet 14 can selectively connect to heating passage 16 or first flow channel 13; first flow channel 13 is connected to hot water inlet 311 of heat exchange passage 310, cold water outlet 312 of heat exchange passage 310 is connected to fourth flow channel 402 of water inlet valve 400, cold water inlet 321 of water supply passage 320 is connected to third flow channel 401 of water inlet valve 400, and hot water outlet 322 of water supply passage 320 is connected to second flow channel 15.

[0040] In use, when the inlet 14 is connected to the heating channel 16, the hot water heated by the combustion chamber 200 flows sequentially through the outlet 201, inlet 14, and heating channel 16 into the heating system 500 to provide heating for users. The water in the heating system 500, after heat exchange with the outside environment, can flow back to the combustion chamber 200 through the inlet valve 400 for reheating, thus forming a heating water circulation loop. When the inlet 14 is connected to the first flow channel 13, the hot water heated by the combustion chamber 200 flows sequentially through the outlet... 201. After the water flows through the inlet 14 and the first flow channel 13, it flows into the heat exchange channel 310 of the heat exchange structure 300. After exchanging heat with the water in the water supply channel 320, it flows through the inlet valve 400 into the combustion chamber 200 to be reheated, thus forming a heat exchange circulation loop. Water from the external water source can flow into the water supply channel 320 of the heat exchange structure 300 through the inlet valve 400. After exchanging heat with the water in the heat exchange channel 310, it flows through the second flow channel 15 and the bathroom channel 17 in sequence into the bathroom system to provide domestic water for users.

[0041] It should be explained that the heating system 500 specifically refers to terminal heat dissipation components such as radiators, underfloor heating pipes, or fan coil units. Water heated in the combustion chamber 200 can be pumped to these terminal heat dissipation components through the outlet valve 100, dissipating heat into the indoor air to raise the indoor ambient temperature and meet the user's heating needs. The bathroom system specifically refers to water-using devices for users to shower, wash, and perform other operations. Therefore, both the heating system 500 and the bathroom system are relatively mature technologies in this field, and the specific structures of the heating system 500 and the bathroom system will not be described in detail in this embodiment.

[0042] It should also be noted that the combustion chamber 200, heat exchange structure 300 and water inlet valve 400 are all relatively mature technologies in the field. The specific structure of the combustion chamber 200, heat exchange structure 300 and water inlet valve 400 will not be described in detail in this embodiment.

[0043] like Figures 2-5 As shown, this embodiment also provides a water outlet valve 100. The valve body 1 of the water outlet valve 100 has a three-way valve chamber 12. The valve body 1 also has a first flow channel 13 that communicates with the three-way valve chamber 12. The first flow channel 13 is used to connect to the hot water inlet 311 of the heat exchange structure 300, thereby delivering hot fluid to the heat exchange channel 310 and heating the cold fluid in the water supply channel 320 through convective heat exchange.

[0044] The valve body 1 is made of plastic and is integrally injection molded, which has the advantages of convenient molding and low cost. The valve body 1 also has a process hole 11 that communicates with the first flow channel 13. The outlet valve 100 also includes a static elimination device 2, which includes a plug assembly 21 and a grounding component 22. The plug assembly 21 is sealed to the process hole 11. One end of the grounding component 22 is coupled to the plug assembly 21 and can be electrically connected to the fluid in the first flow channel 13. The other end of the grounding component 22 is directly or indirectly electrically connected to the ground, forming a grounding conductive path, thereby dissipating the static electricity generated in the fluid in the system, effectively avoiding the continuous accumulation of static electricity in the system, preventing static voltage from causing electric sparks, thereby eliminating safety hazards, protecting system equipment, and extending the service life of the equipment.

[0045] In addition, the static elimination device 2 is installed on the process hole 11 of the valve body 1, without changing the structure and manufacturing process of the existing water outlet valve 100. While solving the static discharge problem, it ensures the advantages of the existing injection-molded integrated structure water outlet valve 100 in terms of convenient molding and low cost in manufacturing process, so that the improved water outlet valve 100 has good practicality and economy.

[0046] In this embodiment, the outer shell of the wall-hung boiler is installed on the wall, and the other end of the grounding component 22 is electrically connected to the outer shell of the wall-hung boiler. The static electricity generated in the fluid is released to the wall through the plug assembly 21, the grounding component 22 and the outer shell of the wall-hung boiler, and flows into the ground through the wall, thereby forming a grounding conductive path. Effective protection can be achieved without a complicated grounding system, with low requirements for the installation environment, reducing installation difficulty and failure probability, and meeting the compliant installation requirements of the wall-hung boiler water system, making it highly practical.

[0047] Of course, in other embodiments, a metal rod can be buried underground, and the other end of the grounding component 22 can be electrically connected to the metal rod through a cable to achieve grounding in the same way. This is not limited here.

[0048] like Figure 5 As shown, the plug assembly 21 in this embodiment includes a plug 211 and a connector 212. The plug 211 is made of metal and is sealed in the process hole 11. The connector 212 is connected to the plug 211 and is used to fix the grounding component 22. The grounding component 22 is electrically connected to the plug 211. Fixing the grounding component 22 with the connector 212 can improve the ease of installation and connection reliability between the plug 211 and the grounding component 22. The grounding component 22 is electrically connected to the fluid through the metal plug 211, thereby forming a stable and reliable conductive path.

[0049] In another optional embodiment, the plug assembly 21 includes a plug 211 and a connector 212. The connector 212 is made of metal. The plug 211 is sealed in the process hole 11 and has a through hole. The connector 212 is sealed through the through hole, and one end of the connector 212 extends into the first flow channel 13. The other end of the connector 212 is electrically connected to the grounding member 22. The grounding member 22 is electrically connected to the fluid through the connector 212, which can also form a stable and reliable conductive path.

[0050] Furthermore, the static eliminator 2 also includes a clamp 24, one end of which clamps the grounding component 22, and the other end of which is coupled to the plug assembly 21. By clamping the grounding component 22 with the clamp 24, the clamp 24 and the grounding component 22 are tightly fitted to form a stable and reliable connection, ensuring a stable static conduction path. Moreover, the coupling between the clamp 24 and the plug assembly 21 makes disassembly and assembly convenient, facilitating later maintenance and component replacement.

[0051] Among them, the connector 212 is a connecting screw, and the plug 211 has an internal thread that mates with the thread of the connecting screw. By using the tightening force of the threaded connection between the connecting screw and the plug 211, the wire clamp 24 can form a tight mechanical contact with the connector 212 and the plug 211, ensuring that the contact surface is not easy to loosen, effectively reducing the contact resistance. The threaded connection method has the advantages of stable connection and easy assembly and disassembly.

[0052] Furthermore, the conductive component also includes a gasket 25, which is sandwiched between the connecting screw and the wire clamp 24. The gasket 25 can increase the tightness of the fit between the connector 212 and the wire clamp 24, thereby increasing the friction between the two and preventing the wire clamp 24 from falling off or sliding. This improves the stability and reliability of the connection between the grounding component 22 and the metal plug 211, further reduces the contact resistance, and ensures the electrostatic transmission efficiency.

[0053] Optionally, the connector 212 can also be a winding post protruding from the plug 211, and the grounding component 22 is wound around the winding post. The winding post provides a clear and fixed connection point for the grounding component 22, which can achieve connection standardization and improve connection reliability. Operators only need to wind the grounding wire according to the operating specifications, which helps to simplify the operation process and improve installation and maintenance efficiency.

[0054] In other alternative embodiments, one end of the grounding member 22 extends through the plug assembly 21 into the first flow channel 13, and the grounding member 22 and the plug 211 are sealed together. The grounding member 22 directly contacts the fluid in the system to form a conductive path, which helps to simplify the structure of the static elimination device 2 and improve the installation efficiency.

[0055] Continue as Figure 5 As shown, the plug 211 has a positioning groove 2111, and the static elimination device 2 also includes a pin 26. The pin 26 can pass through the side wall of the valve body 1 and engage with the positioning groove 2111 to achieve fixed installation of the plug 211 and the valve body 1. The connection method of fixing the plug 211 with the pin 26 is simple and convenient to operate, and can improve the efficiency of disassembly and assembly. In other embodiments, the plug 211 can also be threaded with the process hole 11, which has high connection reliability and can withstand high fluid pressure. The appropriate processing method can be selected according to actual needs, and no limitation is made here.

[0056] To ensure the sealing effect of the process hole 11, the static elimination device 2 also includes a sealing element 27, which is disposed between the plug 211 and the process hole 11 to improve the sealing performance between the plug 211 and the process hole 11.

[0057] It should be noted that the seal 27 is an O-ring, and the metal plug 211 has a circumferentially circumferentially provided limiting groove 2112, within which the O-ring can be placed. The sealing principle of the O-ring is simple, which helps to reduce manufacturing costs; and by placing the O-ring in the limiting groove 2112, the O-ring will not wobble during assembly and rotation of the adjusting parts, effectively improving the convenience of operation.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
