Description

Technical Field

[0001] The present application relates to the technical field of wall-mounted boilers, and in particular to an integrated water channel. Background Art

[0002] The hot water produced by the existing wall-mounted boiler is mainly used for household heating systems and bathroom hot water. The hot water of the heating system is a closed internal circulation, which usually uses a circulating water pump as a power source. The domestic hot water mainly uses cold water to exchange heat with the hot water of the heating system in the heat exchanger to become bathroom hot water.

[0003] The invention patent with application number CN111306782A discloses a wall-mounted boiler. In this technical solution, the domestic water inlet pipeline and the domestic water outlet pipeline are arranged in the middle, while the hot water inlet pipeline and the pipe heating outlet pipeline are arranged on the left and right sides respectively. When connecting with the floor heating pipeline, in order to facilitate the laying of the floor heating pipeline, it is usually necessary to plan and lay the hot water inlet pipeline and the pipe heating outlet pipeline to the same side through additional transition pipelines on the outside. In this process, the transition pipelines connected to the warm water inlet pipeline and the pipe heating outlet pipeline form a cross arrangement with the domestic water inlet pipeline and the domestic water outlet pipeline, which is not convenient for the actual pipe laying work and is prone to errors. Therefore, further improvements can be made. Summary of the invention

[0004] In order to prevent the transition pipes connected to the warm water inlet pipe and the heating water outlet pipe from forming a cross arrangement with the domestic water inlet pipe and the domestic water outlet pipe when laying the floor heating pipes later, so as to facilitate the actual pipe laying work and avoid errors, the present application provides an integrated water circuit.

[0005] The integrated waterway provided in this application adopts the following technical solution:

[0006] An integrated water circuit comprises a bathroom water inlet pipe, a bathroom water outlet pipe, a hot water inlet pipe, a hot water outlet pipe and a bathroom heat exchanger; the bathroom water inlet pipe, the bathroom water outlet pipe, the hot water inlet pipe and the hot water outlet pipe are heat exchanged through the bathroom heat exchanger, and the bathroom water inlet pipe and the bathroom water outlet pipe are arranged on the same side, and the hot water inlet pipe and the hot water outlet pipe are arranged on the same side; a three-way valve is installed on the hot water inlet pipe, a circulating water pump is installed on the hot water outlet pipe, and a flow sensor is installed on the bathroom water inlet pipe.

[0007] By adopting the above technical solution, in actual use, when the flow sensor senses that the bathroom water inlet pipeline is in a closed state, the three-way valve switches to a state where the external heat source heat exchanger and the floor heating pipeline are connected, that is, it switches to a heating mode, and the hot water heated by the external heat source heat exchanger flows into the floor heating pipeline through the three-way valve for heating, and then flows back to the external heat source heat exchanger through the circulating water pump to form a whole heating circulation water circuit for continuous heating. When the flow sensor senses that the bathroom water inlet pipeline is in an open state, the three-way valve switches to a state where the external heat source heat exchanger and the bathroom heat exchanger are connected, that is, it switches to a bathroom mode, and the hot water heated by the external heat source heat exchanger flows into the bathroom heat exchanger through the three-way valve and the hot water inlet pipeline, and then flows back to the external heat source heat exchanger through the hot water outlet pipeline and the circulating water pump. At the same time, bathroom water flows into the bathroom heat exchanger through the bathroom water inlet pipe, and is heated by exchanging heat with the hot water in the bathroom heat exchanger. The heated bathroom water flows out through the bathroom water outlet pipe for use by users.

[0008] In the application, since the bathroom water inlet and outlet pipes are arranged on the same side, and the hot water inlet and outlet pipes are arranged on the same side, when the floor heating pipes are subsequently laid, the transition pipes connected to the warm water inlet and outlet pipes will not form a cross arrangement with the domestic water inlet and outlet pipes, which is convenient for the actual pipe laying work and less prone to errors.

[0009] Optionally, the bathroom heat exchanger is a plate heat exchanger, which is arranged vertically, and the bathroom water inlet pipe is connected to the cold water inlet at the bottom of the bathroom heat exchanger, the bathroom water outlet pipe is connected to the cold water outlet at the top of the bathroom heat exchanger, the hot water inlet pipe is connected to the hot water inlet at the top of the bathroom heat exchanger, and the hot water outlet pipe is connected to the hot water outlet at the bottom of the bathroom heat exchanger.

[0010] By adopting the above technical solution, when used for bathroom, hot water flows in through the hot water inlet at the top of the bathroom heat exchanger, and then flows out from the hot water outlet at the bottom of the bathroom heat exchanger. At the same time, bathroom water flows in from the cold water inlet at the bottom of the bathroom heat exchanger, and then forms a reverse flow with the hot water inside the bathroom heat exchanger for heat exchange and heating, and then flows out from the cold water outlet at the top of the bathroom heat exchanger to achieve the heating of bathroom water. During the heat exchange process, the bathroom water becomes warmer and its density decreases. Therefore, the bathroom water tends to try to surpass the denser fluid, which means that it is easy to rise out of the bathroom heat exchanger. If we do it the other way around, let the bathroom water flow in from the top of the bathroom heat exchanger and out from the bottom of the bathroom heat exchanger, it means that we need to make more efforts (that is, more pumping energy) to pump out the heated bathroom water.

[0011] Optionally, the hot water inlet pipeline from the three-way valve to the bathroom heat exchanger consists of a first pipe section, a second pipe section and a third pipe section in sequence, and the first pipe section and the third pipe section are arranged horizontally, and the second pipe section is arranged vertically; a first filter element is installed on the first pipe section for intercepting and filtering large particles such as scale in the hot water, and a second filter element is installed on the second pipe section for adsorbing and filtering rust stains in the hot water by magnetic attraction, and the first filter element and the second filter element are replaceable and cleaned; a drain pipe is also installed at the bottom of the second pipe section, and a drain valve is installed on the drain pipe.

[0012] By adopting the above technical solution, in the heating mode, since the hot water of the heating system is a closed internal circulation, scale and rust stains are likely to appear inside the floor heating pipes over time. When switching to the bathroom mode, since scale and rust stains remain in the hot water inlet pipe, they are likely to enter the bathroom heat exchanger, seriously affecting the actual heat exchange efficiency of the bathroom heat exchanger.

[0013] In the present application, when the bathroom mode is switched, when hot water is input into the bathroom heat exchanger through the first pipe section, the second pipe section and the third pipe section, the first filter element intercepts and filters the larger particles such as scale in the hot water. At the same time, since the particles of rust stains are relatively small and usually difficult to filter, the second filter element can absorb and filter the rust stains by magnetic attraction, so that scale and rust stains are not easy to enter the bathroom heat exchanger and affect the actual heat exchange efficiency.

[0014] At the same time, before replacing and cleaning the first filter element and the second filter element, the user can open the drain valve on the drain pipe to discharge the sewage in the first pipe section, the second pipe section and the third pipe section, and then take out the filter elements in the first filter element and the second filter element for replacement and cleaning. At this time, since the sewage in the first pipe section, the second pipe section and the third pipe section is discharged in advance, it is not easy for the user to cause sewage leakage during the process of replacing and cleaning the filter element and require subsequent cleaning work, which can ensure the cleanliness, convenience and humanity of the filter element replacement and cleaning process.

[0015] Optionally, a filter cartridge is spliced ​​and installed on the first pipe section, and a first filter element installation cavity is formed at the bottom of the filter cartridge for installation of a first filter element; the first filter element installation cavity is connected to the filter tube barrel, and the first filter element installation cavity is arranged in an oblique upward state toward the three-way valve; the first filter element includes a filter mesh cage portion and an end cover portion, the filter mesh cage portion is fixedly installed on the inward side of the end cover portion, and when the first filter element is installed, the end cover portion in the first filter element is sealed and covered in the first filter element installation cavity, and the filter mesh cage portion in the first filter element extends into the filter tube barrel.

[0016] By adopting the above technical solution, since the filter cage portion extends into the filter tube, when hot water flows through the first filter element, the filter cage portion in the first filter element intercepts and filters larger particles such as scale in the hot water.

[0017] Optionally, the second filter element is in the shape of a rod, and a second filter element installation cavity is formed on the top of the second pipe section for inserting and installing the second filter element, and the second filter element installation cavity is downwardly connected to the second pipe section; a sealing ring is installed in the second filter element installation cavity, and the sealing ring is sleeved on the second filter element; a sealing end cover is threadedly connected to the opening end of the second filter element installation cavity, and a sealing push column is formed inside the sealing end cover; an avoidance opening is opened in the middle of the sealing end cover, and the avoidance opening also passes through the sealing push column and is used for the second filter element to be penetrated and installed.

[0018] When the sealing end cover is tightened, the sealing push pin in the sealing end cover moves downward as the sealing end cover presses the sealing ring to perform sealing between the second filter element and the second filter element installation cavity.

[0019] Optionally, the second filter element includes a filter element rod head and a magnetic cage portion, the magnetic cage portion is coaxially arranged with the filter element rod head, and the magnetic cage portion is fixedly connected to the bottom of the filter element rod head.

[0020] By adopting the above technical solution, after the second filter element is installed, the magnetic mesh cage portion in the second filter element is inserted into the second pipe section to adsorb and filter the rust stains in the hot water flowing through the second pipe section by magnetic attraction.

[0021] Optionally, the second filter element installation cavity is composed of the first cavity section, the second cavity section and the third cavity section from top to bottom, the first cavity section and the third cavity section are both cylindrical, and the diameter of the third cavity section is smaller than the diameter of the first cavity section; the upper and lower ends of the second cavity section are respectively connected to the first cavity section and the third cavity section, and the second cavity section is in the shape of a truncated cone that closes downward; the sealing ring is arranged in the second cavity section, and the outer diameter of the sealing push pin is smaller than the diameter of the first cavity section and larger than the diameter of the third cavity section.

[0022] By adopting the above technical solution, during the process of tightening the locking nut, the sealing end cover is driven to move downward, so that the sealing push pin presses the sealing ring to complete the sealing action.

[0023] Optionally, the bottom section of the sealing push column is provided with a movable clamping block, which is arranged at intervals along the circumferential direction, and each of the movable clamping blocks is slidably connected to the sealing push column along the radial direction of the sealing push column, and the outer side surface of each of the movable clamping blocks is a conical surface that is slidably adapted to the second cavity section.

[0024] By adopting the above technical solution, when the locking nut is tightened to drive the sealing end cover to move downward, on the one hand, the sealing push column continuously presses the sealing ring downward through the movable clamping block at the bottom to complete the sealing action. On the other hand, the movable clamping block at the bottom of the sealing push column is retracted inward to tighten the filter element rod head in the second filter element to achieve synchronous tightening and fixing of the second filter element.

[0025] Optionally, a plurality of guide grooves are provided on the bottom end surface of the sealing push column, the plurality of guide grooves are arranged circumferentially, and each of the guide grooves extends radially along the sealing push column; a sliding block is integrally formed with a sliding block, and the sliding block is slidably arranged in the guiding groove; a return spring is installed in the guiding groove for applying a pre-tightening force to the movable clamp block for moving outward.

[0026] By adopting the above technical solution, in the process of tightening the locking nut to control the movable clamp to retract inwards and tighten the second filter element, the reset spring is compressed and stores energy. In the process of loosening the locking nut, the reset spring is released to assist in pushing the movable clamp to spread and slide outward, so that the movable clamp is reset to an open state, so that in the subsequent process of installing the second filter element again, the second filter element can be directly inserted between the movable clamps and the sealing push column. On the other hand, if the reset spring is not added, at this time, the state of each movable clamp is in a relaxed state, and it cannot be guaranteed that a larger open state can be maintained between the movable clamps for the second filter element to be inserted and installed, and the installation operation is inconvenient.

[0027] Optionally, a damping member is installed between the sealing end cover and the second filter element installation cavity.

[0028] By adopting the above technical solution, on the one hand, when the locking nut is tightened to drive the sealing end cover to move downward, the damping element is compressed synchronously to form a pre-tightening force acting in the direction of the sealing end cover, so that the locking nut is not easy to loosen, so as to further improve the locking stability of the locking nut. On the other hand, during the working process, due to the pure water hammer effect inside the water pipe, when the vibration generated by the water hammer effect is transmitted to the position of the second filter element, the damping element between the sealing end cover and the second filter element installation cavity can absorb and reduce shock, which can not only weaken the loosening caused by the vibration transmitted to the locking nut, but also weaken the noise pollution caused by the vibration.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. In the application, since the bathroom water inlet and outlet pipes are arranged on the same side, and the hot water inlet and outlet pipes are arranged on the same side, when the floor heating pipes are subsequently laid, the transition pipes connected to the heating inlet and outlet pipes will not form a cross arrangement with the domestic water inlet and outlet pipes, which is convenient for the actual pipe laying work and is not prone to errors;

[0031] 2. When used for bathroom, hot water flows in through the hot water inlet at the top of the bathroom heat exchanger, and then flows out from the hot water outlet at the bottom of the bathroom heat exchanger. At the same time, bathroom water flows in from the cold water inlet at the bottom of the bathroom heat exchanger, and then forms a reverse flow with the hot water inside the bathroom heat exchanger to exchange heat and heat, and then flows out from the cold water outlet at the top of the bathroom heat exchanger to achieve the heating of bathroom water. During the heat exchange process, the bathroom water becomes warmer and its density decreases. Therefore, the bathroom water will tend to try to surpass the denser fluid, which means that it is easy to rise out of the bathroom heat exchanger. If we do it the other way around, and let the bathroom water flow in from the top of the bathroom heat exchanger and out from the bottom of the bathroom heat exchanger, it means that we need to make more efforts (that is, more pumping energy) to pump out the heated bathroom water;

[0032] 3. In the present application, when switching to the bathroom use mode, when hot water is input into the bathroom heat exchanger through the first pipe section, the second pipe section and the third pipe section, the first filter element intercepts and filters the larger particles such as scale in the hot water. At the same time, since the particles of rust stains are relatively small, they are usually not easy to be filtered. At this time, the second filter element can absorb and filter the rust stains by magnetic attraction, so that scale and rust stains are not easy to enter the bathroom heat exchanger and affect the actual heat exchange efficiency. At the same time, before replacing and cleaning the first filter element and the second filter element, the user can open the drain valve on the drain pipe to discharge the sewage in the first pipe section, the second pipe section and the third pipe section, and then take out the filter elements in the first filter element and the second filter element for replacement and cleaning. At this time, since the sewage in the first pipe section, the second pipe section and the third pipe section is discharged in advance, it is not easy for the user to cause random leakage of sewage during the replacement and cleaning of the filter element and need to perform subsequent cleaning work, which can ensure the neatness, convenience and humanization of the filter element replacement and cleaning process;

[0033] 4. When tightening the locking nut and driving the sealing end cover to move downward, on the one hand, the sealing push column continuously presses the sealing ring downward through the movable clamping block at the bottom to complete the sealing action. On the other hand, the movable clamping block at the bottom of the sealing push column is retracted inward to tighten the filter rod head in the second filter element to achieve synchronous tightening and fixing of the second filter element.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-6 This application is described in further detail.

[0044] The embodiment of the present application discloses an integrated waterway.

[0045] Reference Figure 1 and Figure 2An integrated water circuit includes a bathroom water inlet pipe 1, a bathroom water outlet pipe 2, a hot water inlet pipe 3, a hot water outlet pipe 4 and a bathroom heat exchanger 5. The bathroom water inlet pipe 1, the bathroom water outlet pipe 2, the hot water inlet pipe 3 and the hot water outlet pipe 4 are heat exchanged through the bathroom heat exchanger 5, and the bathroom water inlet pipe 1 and the bathroom water outlet pipe 2 are arranged on the same side, and the hot water inlet pipe 3 and the hot water outlet pipe 4 are arranged on the same side. The ends of the hot water inlet pipe 3 and the hot water outlet pipe 4 away from the bathroom heat exchanger 5 are used to connect with the external floor heating pipe; a three-way valve 6 is installed on the hot water inlet pipe 3, and one end of the three-way valve 6 is used to connect with the water outlet end of the external heat source heat exchanger for supplying hot water, and the remaining end of the three-way valve 6 is used to connect with the water inlet end of the floor heating pipe. A circulating water pump 7 is installed on the hot water outlet pipe 4, and the outlet end of the circulating water pump 7 is used to connect to the return end of the external heat source heat exchanger for supplying hot water, and the remaining end of the circulating water pump 7 is used to connect to the outlet end of the floor heating pipe. A flow sensor 8 is installed on the bathroom water inlet pipe 1 to sense whether the bathroom water inlet pipe 1 is opened or closed.

[0046] Reference Figure 1 and Figure 3 In actual use, when the flow sensor 8 senses that the bathroom water inlet pipe 1 is in a closed state, the three-way valve 6 switches to a state where the external heat source heat exchanger and the floor heating pipe are connected, that is, it switches to a heating mode. The hot water heated by the external heat source heat exchanger flows into the floor heating pipe through the three-way valve 6 for heating, and then flows back to the external heat source heat exchanger through the circulating water pump 7 to form a whole heating circulation water circuit for continuous heating.

[0047] Reference Figure 1 and Figure 3 When the flow sensor 8 senses that the bathroom water inlet pipe 1 is open, the three-way valve 6 switches to the state where the external heat source heat exchanger and the bathroom heat exchanger 5 are connected, that is, it switches to the bathroom use mode. The hot water heated by the external heat source heat exchanger flows into the bathroom heat exchanger 5 through the three-way valve 6 and the hot water inlet pipe 3, and then flows back to the external heat source heat exchanger through the hot water outlet pipe 4 and the circulating water pump 7. At the same time, the bathroom water flows into the bathroom heat exchanger 5 through the bathroom water inlet pipe 1, and is heated by heat exchange with the hot water in the bathroom heat exchanger 5. The heated bathroom water flows out through the bathroom outlet pipe 2 for users to use.

[0048] Reference Figure 1In the application, since the bathroom water inlet pipe 1 and the bathroom water outlet pipe 2 are arranged on the same side, and the hot water inlet pipe 3 and the hot water outlet pipe 4 are arranged on the same side, when the floor heating pipe is laid later, the transition pipe connected to the warm water inlet pipe and the floor heating water outlet pipe will not form a cross arrangement with the domestic water inlet pipe and the domestic water outlet pipe, which is convenient for the actual pipe laying work and not prone to errors.

[0049] Reference Figure 1 Specifically, in this embodiment, the bathroom heat exchanger 5 is a plate heat exchanger. The bathroom heat exchanger 5 is arranged vertically, and the bathroom water inlet pipe 1 is connected to the cold water inlet at the bottom of the bathroom heat exchanger 5, the bathroom water outlet pipe 2 is connected to the cold water outlet at the top of the bathroom heat exchanger 5, the hot water inlet pipe 3 is connected to the hot water inlet at the top of the bathroom heat exchanger 5, and the hot water outlet pipe 4 is connected to the hot water outlet at the bottom of the bathroom heat exchanger 5.

[0050] When it is in bathroom use mode, hot water flows in through the hot water inlet at the top of the bathroom heat exchanger 5, and then flows out from the hot water outlet at the bottom of the bathroom heat exchanger 5. At the same time, bathroom water flows in from the cold water inlet at the bottom of the bathroom heat exchanger 5, and then forms a reverse flow with the hot water inside the bathroom heat exchanger 5 to exchange heat and heat, and then flows out from the cold water outlet at the top of the bathroom heat exchanger 5 to achieve the heating of bathroom water. During the heat exchange process, the bathroom water becomes warmer and its density decreases. Therefore, the bathroom water tends to try to surpass the denser fluid, which means that it is easy to rise out of the bathroom heat exchanger 5. If we do it the other way around, let the bathroom water flow in from the top of the bathroom heat exchanger 5 and flow out from the bottom of the bathroom heat exchanger 5, it means that we need to make more efforts (that is, more pumping energy) to pump out the heated bathroom water.

[0051] Reference Figure 4 In this embodiment, the hot water inlet pipeline 3 from the three-way valve 6 to the bathroom heat exchanger 5 is sequentially composed of the first pipe section 31, the second pipe section 32 and the third pipe section 33, and the first pipe section 31 and the third pipe section 33 are arranged horizontally, and the second pipe section 32 is arranged vertically. A first filter element 34 is installed on the first pipe section 31, which is used to intercept and filter large particles such as scale in the hot water. A second filter element 35 is installed on the second pipe section 32, which is used to adsorb and filter rust stains in the hot water by magnetic attraction, and the first filter element 34 and the second filter element 35 can be replaced and cleaned. A sewage pipe 36 is also installed at the bottom of the second pipe section 32, and a sewage valve 37 is installed on the sewage pipe 36.

[0052] In the heating mode, since the hot water of the heating system is a closed internal circulation, scale and rust stains are likely to appear inside the floor heating pipes over time. When switching to the bathroom mode, since scale and rust stains remain in the hot water inlet pipe 3, they are likely to enter the bathroom heat exchanger 5, seriously affecting the actual heat exchange efficiency of the bathroom heat exchanger 5.

[0053] In the present application, when the bathroom mode is switched, when hot water is input into the bathroom heat exchanger 5 through the first pipe section 31, the second pipe section 32 and the third pipe section 33, the first filter element 34 intercepts and filters the larger particles such as scale in the hot water. At the same time, since the particles of rust stains are relatively small and usually difficult to be filtered, the second filter element 35 can absorb and filter the rust stains by magnetic attraction, so that scale and rust stains are not easy to enter the bathroom heat exchanger 5 and affect the actual heat exchange efficiency.

[0054] At the same time, before replacing and cleaning the first filter element 34 and the second filter element 35, the user can open the drain valve 37 on the drain pipe 36 to discharge the sewage in the first pipe section 31, the second pipe section 32 and the third pipe section 33, and then take out the filter elements in the first filter element 34 and the second filter element 35 for replacement and cleaning. At this time, since the sewage in the first pipe section 31, the second pipe section 32 and the third pipe section 33 is discharged in advance, it is not easy for the user to cause sewage leakage during the process of replacing and cleaning the filter element and require subsequent cleaning work, which can ensure the neatness, convenience and humanization of the filter element replacement and cleaning process.

[0055] Reference Figure 4 and Figure 5 Specifically, in the present embodiment, a filter cartridge 311 is spliced ​​and installed on the first pipe section 31, and a first filter element 34 installation cavity 312 is formed at the bottom of the filter cartridge 311 for installation of the first filter element 34. The first filter element 34 installation cavity 312 is connected to the filter tube, and the first filter element 34 installation cavity 312 is arranged in an oblique upward state toward the three-way valve 6.

[0056] Among them, the first filter element 34 includes a filter cage portion 341 and an end cover portion 342, the filter cage portion 341 is fixedly installed on the inner side of the end cover portion 342, and the end cover portion 342 is connected and installed with the outer peripheral surface of the first filter element 34 installation cavity 312 by a threaded connection to form a detachable installation, and when the first filter element 34 is installed, the end cover portion 342 in the first filter element 34 is sealed in the first filter element 34 installation cavity 312, and the filter cage portion 341 in the first filter element 34 extends into the filter tube to intercept and filter larger particles such as scale in the hot water flowing through the first filter element 34.

[0057] Reference Figure 6Specifically, in this embodiment, the second filter element 35 is in the shape of a rod, and a second filter element 35 installation cavity 321 is formed at the top of the second pipe section 32 for inserting and installing the second filter element 35, and the second filter element 35 installation cavity 321 is downwardly connected to the second pipe section 32. A sealing ring 322 is installed in the second filter element 35 installation cavity 321, and the sealing ring 322 is sleeved on the second filter element 35. A sealing end cap 323 is threadedly connected to one end of the opening of the second filter element 35 installation cavity 321, and a sealing push column 324 is formed inside the sealing end cap 323. A avoidance opening is opened in the middle of the sealing end cap 323, and the avoidance opening also runs through the sealing push column 324, so as to allow the second filter element 35 to be installed through. When the sealing end cover 323 is tightened, the sealing push pin 324 in the sealing end cover 323 moves downward to press the sealing ring 322 to seal the second filter element 35 and the second filter element 35 installation cavity 321 .

[0058] Reference Figure 6 Specifically, in this embodiment, the second filter element 35 includes a filter element rod head 351 and a magnetic cage portion 352. The magnetic cage portion 352 is coaxially arranged with the filter element rod head 351, and the magnetic cage portion 352 is fixedly connected to the bottom of the filter element rod head 351. Preferably, the magnetic cage portion 352 is made of magnetic nylon material. After the second filter element 35 is installed, the magnetic cage portion 352 in the second filter element 35 is inserted into the second pipe section 32 to absorb and filter the rust stains in the hot water flowing through the second pipe section 32 by magnetic attraction.

[0059] Reference Figure 6 Specifically, in this embodiment, the bottom of the sealing end cover 323 is threadedly connected to the outer periphery of the open end of the second filter element 35 installation cavity 321 through a locking nut 325, and the locking nut 325 and the sealing end cover 323 are rotationally connected.

[0060] Reference Figure 6 Specifically, in this embodiment, the second filter element 35 installation cavity 321 is composed of the first cavity section 3211, the second cavity section 3212 and the third cavity section 3213 from top to bottom. The first cavity section 3211 and the third cavity section 3213 are both cylindrical, and the diameter of the third cavity section 3213 is smaller than the diameter of the first cavity section 3211. The upper and lower ends of the second cavity section 3212 are respectively connected to the first cavity section 3211 and the third cavity section 3213, and the second cavity section 3212 is in a truncated cone shape with a downward closing shape. The sealing ring 322 is arranged in the second cavity section 3212, and the outer diameter of the sealing push pin 324 is smaller than the diameter of the first cavity section 3211 and larger than the diameter of the third cavity section 3213. In the process of tightening the locking nut 325, the sealing end cover 323 is driven to move downward, so that the sealing push pin 324 presses the sealing ring 322 to complete the sealing action.

[0061] Reference Figure 6 and Figure 7 In the present embodiment, a movable clamp block 326 is provided on the bottom section of the sealing push pin 324. The movable clamp blocks 326 are evenly spaced along the circumferential direction, and each movable clamp block 326 is slidably connected to the sealing push pin 324 along the radial direction of the sealing push pin 324, and the outer side surface of each movable clamp block 326 is a conical surface that is slidably adapted to the second cavity section 3212.

[0062] When the locking nut 325 is tightened to drive the sealing end cover 323 to move downward, on the one hand, the sealing push column 324 continuously presses the sealing ring 322 downward through the movable clamping block 326 at the bottom to complete the sealing action. On the other hand, the movable clamping block 326 at the bottom of the sealing push column 324 is retracted inward to tighten the filter element rod head 351 in the second filter element 35, so as to achieve synchronous tightening and fixing of the second filter element 35.

[0063] Reference Figure 7 Specifically, in this embodiment, a plurality of guide grooves 3241 are provided on the bottom end surface of the sealing push column 324, and the plurality of guide grooves 3241 are evenly spaced in the circumferential direction, and each guide groove 3241 extends along the radial direction of the sealing push column 324. Correspondingly, a slider portion 3261 is integrally formed on the movable clamping block 326, and the slider portion 3261 is slidably disposed in the guide groove 3241, so that the movable clamping block 326 can slide inwardly or spread outwardly along the radial direction of the sealing push column 324.

[0064] A return spring 3242 is installed in the guide slot 3241, and one end of the return spring 3242 is connected to the inner side wall of the guide slot 3241, and the other end is connected to the slider portion 3261 in the movable clamping block 326 to apply a pre-tightening force to the movable clamping block 326 to move outward.

[0065] In the process of tightening the locking nut 325 to control the movable clamp block 326 to retract inwards and tighten the second filter element 35, the reset spring 3242 is compressed to store energy. In the process of loosening the locking nut 325, the reset spring 3242 is released to assist in pushing the movable clamp block 326 to spread and slide outward, so that the movable clamp block 326 is reset to an open state, so that in the subsequent process of installing the second filter element 35 again, the second filter element 35 can be directly inserted between the movable clamp blocks 326 and the sealing push column 324. On the other hand, if the reset spring 3242 is not added, at this time, the state of each movable clamp block 326 is in a relaxed state, and it cannot be guaranteed that a larger open state can be maintained between the movable clamp blocks 326 for the second filter element 35 to be inserted and installed, and the installation operation is inconvenient.

[0066] Reference Figure 6In this embodiment, a damping member 327 is installed between the sealing end cover 323 and the installation cavity 321 of the second filter element 35. Preferably, in this embodiment, the damping member 327 is a damping rod, which is vertically arranged and fixedly installed on the inner side wall of the sealing end cover 323, and arranged and installed on the outer periphery of the sealing push column 324.

[0067] On the one hand, when the locking nut 325 is tightened to drive the sealing end cover 323 to move downward, the damping member 327 is compressed synchronously to form a pre-tightening force acting in the direction of the sealing end cover 323, so that the locking nut 325 is not easy to loosen, so as to further improve the locking stability of the locking nut 325. On the other hand, during the working process, due to the water hammer effect inside the water pipe, when the vibration generated by the water hammer effect is transmitted to the position of the second filter element 35, the damping member 327 between the sealing end cover 323 and the second filter element 35 installation cavity 321 can absorb and reduce vibration, which can not only reduce the vibration transmitted to the locking nut 325 and cause loosening, but also reduce the noise pollution caused by the vibration.

[0068] The implementation principle of an integrated waterway in the embodiment of the present application is:

[0069] In actual use, when the flow sensor 8 senses that the bathroom water inlet pipe 1 is closed, the three-way valve 6 switches to the state where the external heat source heat exchanger is connected to the floor heating pipe, that is, it switches to the heating mode. The hot water heated by the external heat source heat exchanger flows into the floor heating pipe through the three-way valve 6 for heating, and then flows back to the external heat source heat exchanger through the circulating water pump 7 to form the entire heating circulation water circuit for continuous heating. When the flow sensor 8 senses that the bathroom water inlet pipe 1 is open, the three-way valve 6 switches to the state where the external heat source heat exchanger is connected to the bathroom heat exchanger 5, that is, it switches to the bathroom mode. The hot water heated by the external heat source heat exchanger flows into the bathroom heat exchanger 5 through the three-way valve 6 and the hot water inlet pipe 3, and then flows back to the external heat source heat exchanger through the hot water outlet pipe 4 and the circulating water pump 7. At the same time, bathroom water flows into the bathroom heat exchanger 5 through the bathroom water inlet pipe 1 to be heated by exchanging heat with the hot water in the bathroom heat exchanger 5. The heated bathroom water flows out through the bathroom water outlet pipe 2 for use by users.

[0070] In addition, when switched to bathroom use mode, the first filter element installed in the hot water inlet pipe 3 from the three-way valve 6 to the bathroom heat exchanger 5 intercepts and filters large particles such as scale in the hot water. The installed second filter element 35 absorbs and filters rust stains in the hot water by magnetic attraction, making it difficult for scale and rust stains to enter the bathroom heat exchanger 5 and affect the actual heat exchange efficiency.

[0071] At the same time, before replacing and cleaning the first filter element 34 and the second filter element 35, the user can open the drain valve 37 on the drain pipe 36 to discharge the sewage in the first pipe section 31, the second pipe section 32 and the third pipe section 33, and then take out the filter elements in the first filter element 34 and the second filter element 35 for replacement and cleaning. At this time, since the sewage in the first pipe section 31, the second pipe section 32 and the third pipe section 33 is discharged in advance, it is not easy for the user to cause sewage leakage during the process of replacing and cleaning the filter element and require subsequent cleaning work, which can ensure the neatness, convenience and humanization of the filter element replacement and cleaning process.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
