Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to a water flow regulating valve and a water heater. Background Technology

[0002] A gas water heater is a device that heats cold water by burning gas. To meet people's demands for a better bathing experience, constant temperature control has become a primary requirement for gas water heater temperature control. To achieve precise control of the outlet water temperature and improve user experience, existing gas water heaters require a water flow regulating valve to adjust the water flow. Existing water flow regulating valves reduce the total water flow area by blocking part of the water passage holes, thereby altering the water flow.

[0003] However, reducing the water flow area will increase the water pressure. The water flow in the water flow regulating valve will directly impact the filter element, causing the filter element to be subjected to a large water pressure impact, which can easily damage the filter element and affect the user's use. Utility Model Content

[0004] The purpose of this utility model is to provide a water flow regulating valve and a water heater that can prevent the filter element from being impacted by excessive water flow, thus avoiding damage to the filter element and improving the user experience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] The valve body includes an inlet and an outlet. A connecting pipe is provided inside the valve body. The connecting pipe has a first water passage hole and a second water passage hole.

[0011] Preferably, the outer contour of the dividing hole has multiple serrations, and the corners between two adjacent serrations are rounded.

[0012] Preferably, the valve body further includes a first support and a second support, the first support and the second support being disposed between the connecting pipe and the second pipe segment, the first support being fixedly connected to the connecting pipe and the second pipe segment, the second support being fixedly connected to the connecting pipe and the second pipe segment, and the water passage hole being located between the first support and the second support.

[0013] Preferably, the water flow regulating valve further includes a temperature sensor, and the valve body further includes a third support member, which is disposed between the connecting pipe and the second pipe section. The third support member is fixedly connected to the connecting pipe and the second pipe section, and the temperature sensor is configured to detect the temperature of the water located between the first support member and the third support member.

[0014] Preferably, the angle between the first support and the second support is greater than 120° along the circumference of the connecting pipe.

[0015] Preferably, the water flow regulating valve further includes a flow detection mechanism, which includes a sleeve, a magnetic rotor, and a Hall element. The sleeve is disposed inside the first pipe section and coaxially arranged with the first pipe section. A first support is provided at one end of the sleeve near the water inlet. The first support includes a plurality of diverting blades spaced apart and inclined along the inner circumference of the sleeve. The magnetic rotor is rotatably disposed inside the sleeve.

[0016] Preferably, the flow detection mechanism further includes a flow stabilizer plate, which includes a fixed ring and a plurality of flow dividers disposed within the fixed ring.

[0017] Preferably, the valve body further includes a pin, and a first assembly groove is provided at the position of the water inlet of the first pipe section. The first assembly groove is used to connect other shaft groove structure components with O-ring seals and to form a radial seal through the O-ring seals. The pin passes through the first pipe section to lock and fix the shaft groove structure component.

[0018] A water heater, including the aforementioned water flow regulating valve.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a water flow regulating valve and a water heater. In this water flow regulating valve, water enters through the inlet and flows out through the outlet after passing through a first and second water passage in the connecting pipe, ensuring the valve's flow capacity. When water demand is high, the switching mechanism opens the second water passage, allowing water to flow through both passages simultaneously, resulting in a larger flow rate. When water demand is low, the switching mechanism closes the second water passage, allowing only the first water passage to flow through, resulting in a smaller flow rate. A filter element is used to filter solid impurities in the water flow. Since the first water passage includes multiple sub-holes, when the second water passage is closed, the excessively high water pressure within the regulating valve is divided and dispersed by these sub-holes. This dispersed hole design significantly reduces the impact on the filter element, preventing damage and improving the user experience. Attached Figure Description

[0034] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] 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 or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or 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 according to the specific circumstances.

[0036] In the description of this utility model, unless otherwise expressly 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.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] This utility model provides a gas water heater, which includes a fan, a combustion chamber, and a heat exchanger. The combustion chamber has an air inlet, and the fan outlet is connected to the air inlet. The fan is used to supply a certain amount of air into the combustion chamber. A burner is located at the bottom of the combustion chamber, and the gas inlet of the burner is connected to a gas pipe. A gas valve is installed on the gas pipe to control the gas intake. That is, by controlling the fan speed, the air supply to the burner can be controlled; by controlling the opening of the gas valve, the gas supply can be controlled; and by controlling the fan speed and the gas valve opening, the air-gas ratio can be controlled, thereby controlling the combustion thermal efficiency and calorific value of the burner.

[0039] The heat exchanger has a cold water inlet and a hot water outlet. An external water supply system (such as a faucet) supplies cold water to the heat exchanger through the cold water inlet. The cold water is heated by the burner within the heat exchanger and then supplied to water-using devices (such as bathing equipment) through the hot water outlet. To achieve precise control of the outlet water temperature and improve user experience, existing gas water heaters require a flow regulating valve to adjust the water flow. Existing flow regulating valves reduce the total water flow area by blocking some of the water passages, thereby altering the water flow. However, reducing the water flow area subjects the filter elements inside the flow regulating valve to greater water pressure impacts, potentially damaging the filter elements and affecting user experience.

[0040] like Figures 1-4 As shown, to solve the above problems, this embodiment provides a water flow regulating valve, which includes a valve body 1, a filter element 16, and a switching mechanism 2. The valve body 1 includes an inlet 11 and an outlet 12. A connecting pipe 13 is provided inside the valve body 1. The connecting pipe 13 has a first water passage hole 131 and a second water passage hole 132. The first water passage hole 131 connects the inlet 11 and the outlet 12, and the second water passage hole 132 connects the inlet 11 and the outlet 12. The switching mechanism 2 is configured to open or close the second water passage hole 132.

[0041] In this water flow regulating valve, water enters from the inlet 11 and flows out from the outlet 12 after passing through a first-stage water passage 131 and a second-stage water passage 132 in the connecting pipe 13, thus ensuring the water flow regulating valve's capacity. Figure 2 As shown, when the water demand is high, the switching mechanism 2 opens the two-stage water passage 132. At this time, the first-stage water passage 131 and the second-stage water passage 132 of the connecting pipe 13 can pass water simultaneously, resulting in a larger water flow rate. Figure 3 As shown, when the water demand is low, the switching mechanism 2 closes the two-stage water passage 132. At this time, the connecting pipe 13 can only use one-stage water passage 131 to pass water, and the water flow rate is small. This water flow regulating valve can quickly and accurately control the water flow rate according to the water demand, and it has a simple structure and low cost.

[0042] like Figure 4 and Figure 5 As shown, the valve body 1 includes a first pipe section 14 and a second pipe section 15. The first pipe section 14 is connected to the side wall of the second pipe section 15 to achieve communication between the first pipe section 14 and the second pipe section 15. The inlet 11 is located at the end of the first pipe section 14 away from the second pipe section 15, and the outlet 12 is located at one end of the second pipe section 15. A connecting pipe 13 is located inside the second pipe section 15. Water entering through the inlet 11 flows through the first pipe section 14 into the second pipe section 15, then flows through the connecting pipe 13 to the outlet 12, and is discharged from the outlet 12.

[0043] like Figures 1-3 As shown, the valve body 1 also includes a filter element 16, which is disposed inside the connecting pipe 13. A first water passage hole 131 is disposed on the side wall of the connecting pipe 13, and a second water passage hole 132 is disposed at the end of the connecting pipe 13 away from the outlet 12. The filter element 16 is disposed inside the connecting pipe 13 and can filter the water flowing through the first water passage hole 131. The filter element 16 can filter some solid impurities in the water flow, preventing solid impurities from passing through the water flow regulating valve.

[0044] In some embodiments, the filter element 16 can also filter water flowing through the two-stage water passage 132.

[0045] Preferably, the first pipe section 14 and the second pipe section 15 are arranged perpendicularly, and a water passage hole 131 of the connecting pipe 13 is opened on the side of the connecting pipe 13 directly opposite the first pipe section 14, so that water from the first pipe section 14 can smoothly pass through the water passage hole 131 into the connecting pipe 13. Figure 6 As shown, a water passage 131 includes multiple branch holes 1311. Through the design of dispersed hole positions, it is possible to avoid the impact on the components when the water flow is too large, and to accurately control the water inlet flow rate.

[0046] Specifically, multiple branch holes 1311 are evenly distributed circumferentially around the central axis of the first pipe section 14, and the outer contour of the branch holes 1311 is a series of serrations, with rounded corners between adjacent serrations to further reduce water flow impact and ensure stable water output.

[0047] like Figure 7 As shown, in order to ensure the stability of the connecting pipe 13, the valve body 1 also includes a first support member 171 and a second support member 172. The first support member 171 and the second support member 172 are disposed between the connecting pipe 13 and the second pipe section 15. The first support member 171 is fixedly connected to the connecting pipe 13 and the second pipe section 15, and the second support member 172 is fixedly connected to the connecting pipe 13 and the second pipe section 15. A water passage hole 131 is located between the first support member 171 and the second support member 172.

[0048] Furthermore, the valve body 1 also includes a third support member 173, which is disposed between the connecting pipe 13 and the second pipe section 15. The third support member 173 is fixedly connected between the connecting pipe 13 and the second pipe section 15, and the first support member 171, the second support member 172, and the third support member 173 are spaced apart from each other, thereby improving the stability of the connecting pipe 13.

[0049] like Figure 2 , Figure 3 and Figure 8 As shown, in order to accurately obtain the water inflow in the first pipe section 14, the water flow regulating valve also includes a flow detection mechanism 3. The flow detection mechanism 3 includes a sleeve 31, a magnetic rotor 32, and a Hall element 33. The sleeve 31 is disposed inside the first pipe section 14 and is coaxially disposed with the first pipe section 14. A first support 311 is disposed at one end of the sleeve 31 near the water inlet 11. The first support 311 includes a plurality of diverting blades 312 that are spaced apart and inclined along the inner circumference of the sleeve 31. The magnetic rotor 32 is rotatably disposed inside the sleeve 31. A plurality of magnetic blades 321 are disposed on the outer circumference of the magnetic rotor 32. The Hall element 33 is disposed outside the first pipe section 14 and corresponds to the magnetic rotor 32.

[0050] When water enters through inlet 11, multiple diverting vanes 312 cause the water entering sleeve 31 to move forward in a spiral shape, driving the magnetic rotor 32 to rotate via magnetic vanes 321. The rotational speed of the magnetic rotor 32 changes linearly with the flow rate. Therefore, Hall element 33 senses the magnetic vanes 321 and outputs a corresponding pulse signal to the controller, which can then determine the water flow rate.

[0051] It is worth noting that the outer circumferential surface of the sleeve 31 abuts against the inner wall of the first pipe, so that all the water entering from the inlet 11 passes through the sleeve 31, thereby ensuring the accuracy of flow monitoring.

[0052] Preferably, the flow detection mechanism 3 further includes a flow stabilizing plate 34. The flow stabilizing plate 34 includes a fixed ring 341 and a plurality of flow dividers 342 disposed within the fixed ring 341. The fixed ring 341 is fixedly disposed at one end of the sleeve 31 near the second pipe section 15. The gap between the flow dividers 342 forms a flow stabilizing gap. When the water pressure is unstable, the flow stabilizing plate 34 can be used to divide a stream of water into multiple streams, thereby achieving pressure reduction and flow stabilization, and ensuring the stability of the water flow.

[0053] Furthermore, the magnetic rotor 32 includes a central rotating shaft 322, and multiple magnetic blades 321 are circumferentially and equally spaced around the outer periphery of the central rotating shaft 322. One end of the central rotating shaft 322 is rotatably connected to the first support 311, and the other end is rotatably connected to the flow stabilizing plate 34. The first support 311 and the flow stabilizing plate 34 are used to fix the axial and radial movement of the magnetic rotor 32, ensuring that the magnetic rotor 32 can only rotate and guaranteeing its stability. At the same time, the first support 311 and the flow stabilizing plate 34 are inherent structures of the flow detection mechanism 3, effectively reducing the structural complexity of the flow detection mechanism 3 and lowering costs.

[0054] To facilitate the assembly of the flow stabilizer plate 34 and the sleeve 31, the outer periphery of the fixing ring 341 is provided with a snap-fit ​​protrusion 343, and the side wall of the sleeve 31 is provided with an L-shaped groove 313 that extends to the end of the sleeve 31. When the fixing ring 341 is inserted into the sleeve 31, the snap-fit ​​protrusion 343 enters the L-shaped groove 313. By rotating the fixing ring 341, the snap-fit ​​protrusion 343 can be snapped and fixed with the L-shaped groove 313.

[0055] Understandably, to reduce the rotational resistance between the magnetic rotor 32 and the first support 311, the first support 311 has a first rotating groove, in which a ball bearing 35 is disposed. The end of the central rotating shaft 322 abuts against the ball bearing 35, allowing the ball bearing 35 to rotate freely within the first rotating groove, thus reducing the resistance experienced by the magnetic rotor 32 during rotation. Similarly, the flow stabilizer 34 has a second rotating groove, in which a ball bearing 35 is disposed. The end of the central rotating shaft 322 abuts against the ball bearing 35, allowing the ball bearing 35 to rotate freely within the second rotating groove, thus reducing the resistance experienced by the magnetic rotor 32 during rotation.

[0056] Furthermore, after the flow detection mechanism 3 is installed into the first pipe section 14, the flow detection mechanism 3 is fixed to the first pipe section 14 by installing a clamp 37 at the inlet 11, which ensures the stability of the flow detection mechanism 3 and has a simple structure that is easy to disassemble and assemble.

[0057] like Figures 5-7 As shown, a component seat 152 is provided on the outside of the valve body 1. The Hall element 33 is fixedly installed in the component seat 152 and sealed and fixed by potting compound 36, so that the Hall element 33 is not affected by the external environment and the Hall element 33 is guaranteed to work stably.

[0058] In this embodiment, the valve body 1 is formed by casting, and along the circumference of the first pipe section 14, the opening direction of the element seat 152 is set at an angle to the opening direction of the outlet 12. This structure makes the core-pulling direction of the outlet 12 different from the core-pulling direction of the element seat 152, thus avoiding mutual interference.

[0059] Preferably, the opening direction of the component seat 152 is perpendicular to the opening direction of the outlet 12. Since the opening direction of the outlet 12 is the axial direction of the second pipe section 15, this structural arrangement can prevent the core-pulling direction of the component seat 152 from being as far apart as possible from the core-pulling directions of both ends of the second pipe section 15 along the axial direction.

[0060] In this embodiment, the valve body 1 also includes a pin 18. A first assembly groove 141 is provided at the inlet 11 of the first pipe section 14, and a second assembly groove 151 is provided at the outlet 12 of the second pipe section 15. Both the first assembly groove 141 and the second assembly groove 151 are used to connect other shaft groove structure components with O-ring seals and form a radial seal through the O-ring seals. Both the first pipe section 14 and the second pipe section 15 are provided with pins 18, which can lock and fix the corresponding shaft groove structure components.

[0061] Understandably, when adjusting water flow, it's necessary to obtain not only water volume data but also water temperature data. For example... Figure 1 As shown, in order to achieve the above purpose, the water flow regulating valve also includes a temperature sensor 4. A sensor seat 142 is provided on the second pipe section 15. The temperature sensor 4 is fixedly installed in the sensor seat 142, and the detection end of the temperature sensor 4 is inserted into the second pipe section 15 to perform temperature detection.

[0062] To facilitate the detection of average water temperature by the temperature sensor 4, the angle between the first support member 171 and the second support member 172 along the circumference of the connecting pipe 13 is greater than 120°, and the detection end of the temperature sensor 4 is located between the first support member 171 and the second support member 172. This structure results in a larger chamber for the detection end of the temperature sensor 4, allowing for a larger water volume and less noticeable water temperature changes, thus enabling accurate detection of the average water temperature.

[0063] It is worth noting that, in order to ensure the connectivity of the three chambers formed between each pair of the first support member 171, the second support member 172, and the third support member 173, each of the three support members is spaced apart from the end face of the connecting pipe 13 opposite to the outlet 12. This structure ensures that when the sealing member 22 of the switching mechanism 2 abuts against and seals the second water passage, it prevents the sealing member 22 from blocking the three chambers formed between each pair of the first support member 171, the second support member 172, and the third support member 173, thus ensuring the connectivity between the three chambers and facilitating water flow into them.

[0064] like Figures 1-3 As shown, the switching mechanism 2 includes a solenoid valve 21 and a seal 22. The solenoid valve 21 includes a valve core, and the seal 22 is disposed between the valve core and the two-stage water passage 132. The valve core drives the seal 22 to move to open or close the two-stage water passage 132.

[0065] When water demand is low, solenoid valve 21 is energized, and the valve core of solenoid valve 21 moves towards the secondary water passage 132, causing the sealing element 22 to abut against the connecting pipe 13 to close the secondary water passage 132. At this time, water can only pass through the primary water passage 131 of the connecting pipe 13, and the water flow is small. When water demand is high, solenoid valve 21 is de-energized, and the sealing element 22 can push the valve core under water pressure and return to its original position, causing the sealing element 22 to disengage from the connecting pipe 13 to open the secondary water passage 132. At this time, water can pass through both the primary water passage 131 and the secondary water passage 132 of the connecting pipe 13 simultaneously, and the water flow is large.

[0066] 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 other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations 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.
