Description

Technical Field

[0001] This manual relates to the field of water heater technology, and in particular to a valve and a hot water system. Background Technology

[0002] Currently, in order to achieve zero cold water output in hot water systems, a one-way valve is usually installed in the water circuit of the hot water system. After the hot water passes through the one-way valve, it circulates back to the cold water pipe, thereby preheating the water in the hot water system.

[0003] However, when the check valve is installed in a circulating pipeline with a high concentration of magnetic materials such as iron powder, the adsorption rate of the currently mass-produced magnetic rod filters is relatively low. The magnetic materials cross the filter screen area and are adsorbed onto the valve core surface, causing the valve core to jam and fail to complete the opening and closing action, resulting in valve failure.

[0004] There is currently no effective solution to the above problems. Utility Model Content

[0063] The valve in the embodiments of this specification includes a valve body, a valve core, and a filter assembly.

The first tubular body is connected to at least a portion of the magnet assembly, allowing the first tubular body to be magnetized. Therefore, during the process of water flowing into the first tubular body through the first connecting portion and then out of the first tubular body through the second connecting portion, magnetic impurities in the water flowing towards the valve core can be adsorbed not only by the magnet assembly but also by the first tubular body. This increases the adsorption area of ​​the filter assembly, thereby improving the filtration effect and preventing excessive magnetic impurities from adsorbing onto the valve core, which could lead to poor sealing or valve jamming. This ensures the valve can operate stably for a long period.

[0089] This specification provides an example of a valve. Figures 1 to 3 The front view, top view, and cross-sectional view of the valve in the embodiments of this specification are shown respectively. Figure 3 As shown, valve 10 may include valve body 101, valve core 102, and filter assembly 103. A flow channel is provided inside the valve body 101. Water can flow within the flow channel.

[0090] Valve core 102 is disposed within the flow channel. Valve core 102 is used to open or close the flow channel. When valve core 102 is open, water can flow throughout the entire flow channel.

[0091] The filter assembly 103 is at least partially disposed within the flow channel and located upstream of the valve core 102. Please refer to... Figures 4 to 6 The diagrams show a schematic diagram, a front view, and a cross-sectional view of the filter assembly in the embodiments of this specification. Figures 4 to 6As shown, the filter assembly 103 includes a first tubular body 131 and a magnet assembly 133. The first tubular body 131 has a first connecting portion 1311 and a second connecting portion 1312 located downstream of the first connecting portion 1311. Water in the flow channel flows into the first tubular body 131 through the first connecting portion 1311, then flows out of the first tubular body 131 through the second connecting portion 1312 and flows to the valve core 102. At least a portion of the magnet assembly 133 is made of a magnetic material. The magnet assembly 133 is magnetic. The first tubular body 131 is connected to at least a portion of the magnet assembly 133. The first tubular body 131 can be magnetized by the magnet assembly 133. In one embodiment, the first tubular body 131 may be made of soft magnetic stainless steel, making it not only easily magnetized but also preventing water corrosion.

[0092] In the above embodiments, valve 10 may include valve body 101, valve core 102, and filter assembly 103. Filter assembly 103 may include first tubular body 131 and magnet assembly 133. First tubular body 131 is connected to at least part of magnet assembly 133, so that first tubular body 131 is magnetically transmitted. Therefore, during the process of water flowing into first tubular body 131 through first connecting part 1311 and then flowing out of first tubular body 131 through second flow part, magnetic impurities in the water flowing towards valve core 102 can be adsorbed not only by magnet assembly 133 but also by first tubular body 131. This can increase the adsorption area of ​​filter assembly 103, thereby improving the filtration effect and avoiding the occurrence of poor sealing or valve jamming caused by excessive magnetic impurities adsorbing valve core 102. This ensures that valve 10 can work stably for a long time.

[0093] like Figure 1 and Figure 3 As shown, in some embodiments of this specification, the flow channel has at least a first inlet 105 for hot water and a second inlet 106 for cold water. At least a portion of the filter assembly 103 and the valve core 102 are sequentially disposed within the flow channel between the first inlet 105 and the second inlet 106. The valve core 102 is capable of unidirectionally opening the flow channel along the direction from the first inlet 105 to the second inlet 106. The first inlet 105 is connected to a first connecting portion 1311. Water flowing into the flow channel from the first inlet 105 can enter the first tubular body 131 via the first connecting portion 1311, and then flow to the valve core 102 via the second connecting portion 1312.

[0094] like Figure 1 and Figure 3 As shown, in some embodiments of this specification, the extending direction of the filter assembly 103 is parallel to the extending direction of the valve body 101. By setting the extending direction of the filter assembly 103 to be parallel to the extending direction of the valve body 101, the filtration area of ​​the filter assembly 103 can be increased, thereby improving the filtration effect.

[0095] In some embodiments of this specification, a mounting port for mounting a filter assembly 103 is formed on the valve body 101. The mounting port communicates with the flow channel. The mounting port is located upstream of the first inlet 105 and the second inlet 106. At least a portion of the filter assembly 103 can extend into the flow channel through the mounting port. The filter assembly 103 can be mounted to the valve body 101 through the mounting port, thereby filtering the fluid within the valve body 101.

[0096] like Figure 1 and Figure 3 As shown in some embodiments of this specification, the flow channel is further provided with a first outlet 107 and a second outlet 108. The first outlet 107 is connected to the first inlet 105. The second outlet 108 is connected to the second inlet 106. The valve core 102 is located between the first outlet 107 and the second outlet 108. When the valve 10 is closed, water flowing into the flow channel from the first inlet 105 can flow to the first outlet 107, and water flowing into the flow channel from the second inlet 106 can flow to the second outlet 108.

[0097] like Figure 1 and Figure 3 As shown, in some embodiments of this specification, the opening of the first inlet 105 is perpendicular to the extending direction of the valve body 101. The opening of the first outlet 107 is parallel to the opening of the first inlet 105.

[0098] In some embodiments of this specification, the opening of the second inlet 106 is perpendicular to the extending direction of the valve body 101. The opening of the second outlet 108 is parallel to the opening of the second inlet 106.

[0099] In some embodiments of this specification, the opening of the mounting port is oriented parallel to the extension direction of the valve body.

[0100] In some embodiments of this specification, at least a portion of the filter assembly 103 is located between the first inlet 105 and the first outlet 107. By disposing at least a portion of the filter assembly 103 between the first inlet 105 and the first outlet 107, water flowing from the first inlet 105 to the second inlet 106 can be filtered, as can water flowing from the first inlet 105 to the first outlet 107.

[0101] In some embodiments of this specification, the valve core 102 is a magnetically aspirated valve that allows unidirectional flow from the first inlet 105 to the second inlet 106. The magnetically aspirated valve may include a blocking member 121 and a suction member 122 that are magnetically attracted to each other. When the pressure difference between the two sides of the blocking member 121 in the direction from the first inlet 105 to the second inlet 106 is greater than the attractive force between the blocking member 121 and the suction member 122, the blocking member 121 moves to the position where the valve core 102 is open. When the pressure difference between the two sides of the blocking member 121 in the direction from the first inlet 105 to the second inlet 106 is less than the attractive force between the blocking member 121 and the suction member 122, the blocking member 121 moves to the position where the valve core 102 is closed. Thus, the unidirectional flow of the valve core 102 from the first inlet 105 to the second inlet 106 can be controlled.

[0102] Furthermore, at least one of the sealing element 121 and the suction element 122 is made of a magnetic material. Magnetic valves readily attract magnetic media, thus requiring the filter assembly 103 to filter the water flowing towards the magnetic valve.

[0103] like Figures 4 to 6 As shown, in some embodiments of this specification, the first connecting portion 1311 may be disposed on the side wall of the first tubular body 131. The extending direction of the first tubular body 131 is the same as the extending direction of the flow channel. By disposing the first connecting portion 1311 on the side wall of the first tubular body 131, the contact area between the water flow and the first tubular body 131 can be increased, thereby improving the adsorption efficiency of magnetic impurities.

[0104] In some embodiments of this specification, such as Figures 1 to 3 As shown, the second connecting part 1312 can be disposed on the side wall of the first tubular body 131. By disposing of the second connecting part 1312 on the side wall of the first tubular body 131, water flow can be prevented from directly impacting the valve core 102, thereby improving the impurity filtration efficiency.

[0105] It is understood that, in some embodiments of this specification, the second connecting portion 1312 may be disposed on the end of the first tubular body 131. In some embodiments of this specification, the second connecting portion 1312 may be disposed on the side wall and end of the first tubular body 131. Here, the end refers to the end of the first tubular body 131 near the valve core 102.

[0106] Please refer to Figures 7 to 12 This diagram illustrates the structure of the first tubular body 131 in an embodiment of this specification. Figures 7 to 12 As shown, the first connecting portion 1311 may be disposed on the side wall of the first tubular body 131. The second connecting portion 1312 may be disposed on the side wall and / or end of the first tubular body 131.

[0107] In some embodiments of this specification, such as Figure 7 , Figure 8 and Figure 12 As shown, the first connecting part 1311 may include a connecting port on the side wall of the first tubular body 131, through which water in the first flow channel can enter the first tubular body 131.

[0108] In some embodiments of this specification, such as Figure 9 and Figure 11 As shown, the first connecting portion 1311 may include a filter screen on the side wall of the first tubular body 131. Water in the first flow channel can enter the first tubular body 131 through the holes in the filter screen. By configuring the first connecting portion 1311 as a filter screen on the side wall, the first tubular body 131 can filter not only magnetic impurities in the water flow, but also non-magnetic impurities in the water flow.

[0109] In some embodiments of this specification, such as Figure 10 As shown, the first connecting portion 1311 may include a connecting port and a filter screen disposed on the side wall of the first tubular body 131. By configuring the first connecting portion 1311 as a connecting port and a filter screen on the side wall, the first tubular body 131 can filter not only magnetic impurities in the water flow, but also non-magnetic impurities in the water flow. Moreover, even if the filter screen is blocked by impurities, the water flow can still enter the first tubular body 131 through the connecting port.

[0110] In some embodiments of this specification, such as Figures 7 to 12 As shown, the second connecting portion 1312 may include a connecting port and / or a filter screen on the side wall and / or end of the first tubular body 131.

[0111] In some embodiments of this specification, such as Figure 7 , Figure 8 and Figure 9 As shown, the second connecting portion 1312 may include a connecting port. By setting the second connecting portion 1312 as a connecting port on the side wall and / or end of the first tubular body 131, water flowing into the first tubular body 131 can flow out of the first tubular body 131 through the connecting port and then flow to the valve core 102.

[0112] In some embodiments of this specification, such as Figure 11 and Figure 12 As shown, the second connecting portion 1312 may include a filter screen. By configuring the second connecting portion 1312 as a filter screen, magnetic and non-magnetic impurities in the water flow can be filtered simultaneously as the water flows through the second connecting portion 1312.

[0113] In some embodiments of this specification, such as Figure 10As shown, the second connecting portion 1312 may include a connecting port and a filter screen disposed on the side wall and / or end of the first tubular body 131. By configuring the second connecting portion 1312 to include a filter screen and a connecting port, magnetic and non-magnetic impurities in the water flow can be filtered simultaneously when water flows through the second connecting portion 1312. Moreover, even if the filter screen is blocked by impurities, the water flow can still exit the first tubular body 131 through the connecting port.

[0114] like Figure 3 As shown, in some embodiments of this specification, valve 10 may further include a blocking portion 104. The blocking portion 104 is disposed on the outer side of the first tubular body 131 between the first connecting portion 1311 and the second connecting portion 1312. The blocking portion 104 abuts against the inner wall of valve body 101 and the outer wall of the first tubular body 131 to block water flow. By providing the blocking portion 104 on the outer side of the first tubular body 131 between the first connecting portion 1311 and the second connecting portion 1312, water in the flow channel first flows into the first tubular body 131 from the first connecting portion 1311 and then flows out of the tubular body from the second connecting portion 1312, preventing water in the flow channel from flowing into the first tubular body 131 via the second connecting portion 1312.

[0115] In some embodiments of this specification, such as Figure 3 As shown, the blocking portion 104 can be formed from a portion of the inner wall of the valve body 101. For example, the blocking portion 104 can be integrally formed from the valve body 101.

[0116] It is understood that, in some embodiments of this specification, the blocking portion 104 may be formed from a portion of the outer wall of the first tubular body 131. For example, it may be formed by protruding outward from the outer wall of the first tubular body 131. In some embodiments of this specification, the blocking portion 104 may be formed jointly from a portion of the outer wall of the first tubular body 131 and a portion of the inner wall of the valve body 101.

[0117] In some embodiments of this specification, at least a portion of the magnet assembly 133 may be disposed within the first tubular body 131. It is understood that, in some embodiments of this specification, at least a portion of the magnet assembly 133 may also be configured to connect to an end of the first tubular body 131. Here, "end" may refer to the end of the first tubular body 131 near the valve core 102.

[0118] like Figure 6 As shown, the magnet assembly 133 can be disposed within the first tubular body 131. By disposing of the magnet assembly 133 within the first tubular body 131, the volume of the filter assembly 103 can be reduced.

[0119] like Figure 6 As shown, in some embodiments of this specification, the magnet assembly 133 may include a first magnet 1331. The first magnet 1331 is disposed within the first tubular body 131 (e.g., Figure 6 (As shown) or near the end of the first tubular body 131. By providing the first magnet 1331 inside the first tubular body 131 or near the end of the first tubular body 131, it is convenient for the first magnet 1331 to magnetize the first tubular body 131.

[0120] like Figure 6 As shown, in some embodiments of this specification, the magnet assembly 133 may further include a fixing member 1333. The fixing member 1333 is used to fix the first magnet 1331 inside the first tubular body 131. In this way, the first magnet 1331 can be fixedly installed inside the first tubular body 131, which facilitates the magnetization of the first tubular body 131.

[0121] In one embodiment, the fastener 1333 can be magnetized by the first magnet 1331, and the fastener 1333 can contact the first tubular body 131 to magnetize the first tubular body 131.

[0122] In some embodiments of this specification, such as Figure 6 As shown, the magnet assembly 133 may further include a second magnet 1332. The second magnet 1332 is spaced apart from the first magnet 1331. A first connecting portion 1311 is located between the first magnet 1331 and the second magnet 1332. The second magnet 1332 is configured to attract the first magnet 1331. By providing the second magnet 1332 that attracts the first magnet 1331, the magnetism of the filter assembly 103 can be enhanced, thereby further improving the filtration effect of magnetic impurities.

[0123] In some embodiments of this specification, such as Figure 6 As shown, the first magnet 1331 is closer to the valve core 102 than the second magnet 1332. The first magnet 1331 is disposed inside the first tubular body 131, and the second magnet 1332 can be disposed on the side of the first tubular body 131 away from the valve core 102.

[0124] like Figure 6 As shown, in some embodiments of this specification, the filter assembly 103 may further include a second tubular body 132. The second tubular body 132 is disposed within the first tubular body 131. Please refer to... Figure 13 This diagram illustrates the structure of the second tubular body in an embodiment of this specification. Figure 13As shown, the second tubular body 132 is provided with a third connecting portion 1321 and a fourth connecting portion 1322 located downstream of the third connecting portion 1321. Water in the flow channel can flow into the gap between the first tubular body 131 and the second tubular body 132 through the first connecting portion 1311, then flow into the second tubular body 132 through the third connecting portion 1321, and the water flowing into the second tubular body 132 flows into the first tubular body 131 through the fourth connecting portion 1322, and then flows out of the first tubular body 131 through the second connecting portion 1312 and flows to the valve core 102. By setting the second tubular body 132 inside the first tubular body 131, water can flow into the first tubular body 131 and then into the second tubular body 132 through the third connecting portion 1321, which can disturb the water flow and increase the probability of the water flow contacting the first tubular body, thereby further improving the filtration effect.

[0125] In some embodiments of this specification, the second tubular body 132 is connected to the first tubular body 131. In one embodiment, an end of the second tubular body 132 is connected to an end of the first tubular body 131. In one embodiment, a portion of the inner wall of the first tubular body 131 extends inward to connect with the outer wall of the second tubular body 132. In another embodiment, a portion of the outer wall of the second tubular body 132 extends outward to connect with the inner wall of the first tubular body 131.

[0126] In some embodiments of this specification, the second tubular body 132 is connected to the magnet assembly 133. The second tubular body 132 can be fixed inside the first tubular body 131 by the magnet assembly 133.

[0127] like Figure 6 and Figure 13 As shown, in some embodiments of this specification, a third connecting portion 1321 is disposed on the side wall of the second tubular body 132. By disposing the third connecting portion 1321 on the side wall of the second tubular body 132, water flowing between the first tubular body 131 and the second tubular body 132 can flow into the second tubular body 132 through the third connecting portion 1321.

[0128] In some embodiments of this specification, such as Figure 13 As shown, the fourth connecting portion 1322 is provided at the end of the second tubular body 132. Here, the end refers to the end of the second tubular body 132 near the valve core 102. Water flowing into the second tubular body 132 via the third connecting portion 1321 can flow out of the second tubular body 132 through the fourth connecting portion 1322.

[0129] In some embodiments of this specification, the third connecting portion 1321 may include a connecting port and / or a filter screen. By configuring the third connecting portion 1321 as a connecting port and / or a filter screen, water between the first tubular body 131 and the second tubular body 132 can flow into the second tubular body 132, and impurities in the water flow can also be filtered.

[0130] In some embodiments of this specification, the fourth connecting portion 1322 may include a connecting port and / or a filter screen. By configuring the fourth connecting portion 1322 as a connecting port and / or a filter screen, water in the second tubular body 132 can flow to the second connecting portion 1312, and impurities in the water flow can also be filtered.

[0131] like Figure 4 As shown, in some embodiments of this specification, the projection of the first connecting portion 1311 onto the second tubular body 132 along the normal direction only partially overlaps with or is completely offset from the third connecting portion 1321. In some embodiments of this specification, the projection of the third connecting portion 1321 onto the first tubular body 131 along the normal direction only partially overlaps with or is completely offset from the first connecting portion 1311. By setting the first connecting portion 1311 and the third connecting portion 1321 to be offset from each other to form a turbulence structure, turbulence can be generated within the first tubular body 131, increasing the contact probability between the water flow and the first tubular body 131 and the second tubular body 132, thereby improving the impurity filtration effect.

[0132] In some embodiments of this specification, when the first connecting portion 1311 on the first tubular body 131 and the third connecting portion 1321 on the second tubular body 132 are staggered to form a turbulence structure, the second connecting portion 1312 can be provided only on the side wall of the first tubular body 131, and the end of the first tubular body 131 near the valve core 102 is sealed. This improves the water mixing effect of the turbulence structure and further enhances the impurity filtration effect.

[0133] In some embodiments of this specification, the filter assembly 103 may further include a cap 135. The cap 135 is used to seal the end of the first tubular body 131 near the valve core 102. Figure 4 and Figure 5 As shown, the end of the first tubular body 131 near the valve core 102 can be sealed by the cap 135 to improve the mixing effect of the turbulence structure, thereby improving the impurity filtration effect.

[0134] In some embodiments of this specification, the second tubular body 132 is connected to at least a portion of the magnetic assembly 133, and the second tubular body 132 can be magnetized by the magnetic assembly. Water in the flow channel can enter between the first tubular body 131 and the second tubular body 132 via the first connecting portion 1311, flow into the second tubular body 132 via the third connecting portion 1321, flow out of the second tubular body 132 via the fourth connecting portion 1322, and then flow out of the first tubular body 131 via the second connecting portion 1312. During this process, magnetic impurities in the water flow can be adsorbed by the first tubular body 131 and the second tubular body 132, which can further improve the magnetic impurity filtration efficiency.

[0135] like Figure 6 As shown in some embodiments of this specification, the magnet assembly 133 is disposed within the first tubular body 131. At least a portion of the magnet assembly 133 is used to prevent water flowing between the first tubular body 131 and the second tubular body 132 from flowing directly to the second connecting portion 1312. This ensures that water between the first tubular body 131 and the second tubular body 132 can only flow into the second tubular body 132 through the third connecting portion 1321 on the second tubular body 132, and then flow to the second connecting portion 1312 on the first tubular body 131 through the fourth connecting portion 1322 on the second tubular body 132. This allows the water to pass sequentially through the first tubular body 131 and the second tubular body 132 for filtration, improving both the filtration effect and the turbulence effect.

[0136] In some embodiments of this specification, the magnet assembly 133 may include a first magnet 1331. The first magnet 1331 is a ring magnet. The fourth connecting portion 1322 of the second tubular body 132 is connected to the hollow portion of the ring magnet, allowing water in the second tubular body 132 to flow to the second connecting portion 1312 via the fourth connecting portion 1322 and the hollow portion of the ring magnet. The annular portion of the ring magnet can block the water flow within the annular gap between the first tubular body 131 and the second tubular body 132, preventing water from flowing directly to the second connecting portion 1312.

[0137] In some embodiments of this specification, the filter assembly 103 may further include a connector 134. The connector 134 is connected to the end of the first tubular body 131 away from the valve core 102. The connector 134 is also detachably connected to the valve body 101. The valve body 101 is provided with an installation port that communicates with the flow channel. At least a portion of the filter assembly 103 can extend into the flow channel through the installation port and be detachably connected to the valve body 101 through the connector 134. By providing the connector 134, the filter assembly 103 can be detachably connected to the valve body 101, facilitating the removal and cleaning of the filter assembly 103 from the valve body 101 and preventing the filter assembly 103 from being blocked by impurities, which could lead to valve 10 failure.

[0138] like Figure 6As shown, in some embodiments of this specification, a sealing element 1341 is provided on the connector 134, and the sealing element 1341 is used for sealing connection with the inner wall of the valve body 101. By sealing the inner wall of the valve body 101 with the sealing element 1341, the sealing performance of the flow channel inside the valve body 101 can be guaranteed.

[0139] like Figure 6 As shown, in some embodiments of this specification, the magnet assembly 133 may include a first magnet 1331 and a second magnet 1332. The first magnet 1331 is disposed within the first tubular body 131. The second magnet 1332 is disposed within the connector 134, and the second magnet 1332 is configured to attract the first magnet 1331. By disposing of the second magnet 1332 within the connector 134, the magnetism of the filter assembly 103 can be enhanced, thereby improving the filtration effect of magnetic impurities. Furthermore, compared to disposing of the second magnet 1332 alone, disposing of the second magnet 1332 within the connector 134 can reduce the volume of the filter assembly 103, thereby reducing the volume of the valve 10.

[0140] This specification also provides a hot water system. The hot water system may include a hot water device and a valve as described in any of the above embodiments, the valve being connected to the water circuit of the hot water device.

[0141] Please refer to Figure 14 A schematic diagram of the hot water system in an embodiment of this specification is shown. Figure 14 As shown, the first inlet 105 of valve 10 is connected to the outlet of hot water device 11 via hot water pipe 12. The second inlet 106 of valve 10 is connected to the inlet of hot water device 11 via cold water pipe 13. The first outlet 107 and the second outlet 108 of valve 10 are respectively connected to water-using device 2.

[0142] When a user needs hot water, i.e., when the user turns on the hot water switch of water-using device 2, valve 10 is in the closed state. The hot water heated by the hot water equipment 11 enters the hot water pipe 12. The hot water in the hot water pipe 12 enters valve 10 through the first inlet 105, and then enters the water-using element through the first outlet 107 of valve 10 and is supplied to water-using device 2. The cold water in the cold water pipe 13 can enter valve 10 through the second inlet 106, and then enter the water-using element through the second outlet 108 of valve 10 and is supplied to water-using device 2. In addition, hot and cold water can be mixed in the water-using element to form warm water according to the user's water temperature requirements before being supplied to water-using device 2. When there is no demand for hot water at the user end, that is, when the user turns off the switch of the water device 2, the valve 10 is in the conducting state, and the water device 2 does not supply water to the user end. The hot water heated by the hot water equipment 11 enters the hot water equipment 11 for circulation heating in sequence through the hot water pipe 12, the valve 10 and the cold water pipe 13, so as to achieve the purpose of circulation preheating. The user end can use hot water in time when using water, thereby achieving zero cold water in the water circuit.
