Description

Technical Field

[0001] The utility model relates to the technical field of water supply, in particular to a water treatment device, a water heater and purified drinking water equipment. Background Art

[0002] Gas water heaters are household appliances that use gas to heat water flowing through heat exchange tubes to provide hot water. Because tap water contains many impurities, especially when gas water heaters are used in areas with poor water quality, scaling can easily form inside the heat exchange tubes over time, affecting the water flow rate and thermal efficiency of the tubes, and even causing pipe blockages.

[0003] The prior art provides a gas water heater, which includes a water heater shell, a water inlet pipe joint is provided at the bottom of the water heater shell, and a purification device is provided inside the water inlet pipe joint. The purification device includes a magnetic ring and a scale-inhibiting purification filter. The magnetic ring is used to adsorb iron filings and impurities in the water, and the scale-inhibiting purification filter is filled with scale-inhibiting filter material to filter and purify impurities in the water.

[0004] Although the gas water heater provided by the prior art can purify the water passing through the heat exchange tube, since the purification device uses a magnetic ring and a filter to adsorb impurities, the impurities will accumulate inside the purification device, so that the purification device needs to be cleaned and replaced regularly, which increases the inconvenience of users in using the gas water heater. Utility Model Content

[0005] One of the technical problems solved by the present invention is to provide a water treatment device that can effectively solve the problem of the existing water treatment device that the water treatment device needs to be cleaned regularly due to the accumulation of impurities inside the water treatment device, thereby improving the ease of use of the water treatment device.

[0006] The second technical problem solved by the present invention is to provide a water heater that can effectively solve the problem of reduced convenience of use of existing water heaters due to the need for regular cleaning of the water treatment device, while reducing the probability of scaling in the water heater pipes and improving the convenience of use of the water heater.

[0007] The third technical problem solved by the present invention is to provide a drinking water purifying hot water device, which can effectively solve the problem of inconvenience in use of existing drinking water purifying hot water devices due to the need for regular cleaning or replacement of water treatment devices, thereby improving the convenience of use of the drinking water purifying hot water device.

[0051] Example 1

[0052] like Figures 1 to 7 As shown, this embodiment provides a water treatment device 1, which adopts the principle of ion polarization scale inhibition to reduce the probability of precipitation of substances in the water flowing through the water treatment device 1, thereby reducing the probability of scale generation. At the same time, there is no need to frequently repair and replace the water treatment device 1, thereby improving the ease of use of the water treatment device 1.

[0053] like Figures 1 to 4As shown, in this embodiment, the water treatment device 1 includes a housing 11 and a polarization assembly. The housing 11 has a water holding chamber 115, a water inlet 1121, and a water outlet 1131, and the water inlet 1121 and the water outlet 1131 are both connected to the water holding chamber 115; the polarization assembly includes a plurality of polarization members 12 arranged in the water holding chamber 115, and the plurality of polarization members 12 are arranged in sequence from the water inlet 1121 to the water outlet 1131. Each polarization member 12 includes a plurality of polarization components 121 arranged around a preset axis, from the water inlet 1121 to the water outlet 1131, and each polarization component 121 is inclined in a clockwise direction or a counterclockwise direction, and of two adjacent polarization members 12, the polarization component 121 of one polarization member 12 is inclined in a clockwise direction, and the polarization component 121 of the other polarization member 12 is inclined in a counterclockwise direction. The polarization component 121 is used to polarize and ionize the water flowing through it.

[0054] The water treatment device 1 provided in this embodiment has a plurality of polarization members 12 arranged at intervals along the water inlet 1121 to the water outlet 1131. When the water flows through the polarization member 12, substances containing elements such as calcium, magnesium, and iron in the water flow are formed into ions that are not easy to precipitate under the polarization action of the polarization member 121, so that the substances in the water flowing out of the water outlet 1131 are mostly ionic substances that are not easy to precipitate, thereby reducing the probability of the substances precipitating in the subsequent pipelines, and there will be no problem of the water treatment device 1 needing to be cleaned and replaced due to the precipitation and accumulation of substances in the water treatment device 1. While reducing the probability of scale formation, the performance of the water treatment device 1 is improved. At the same time, since the plurality of polarization members 12 are arranged from the water inlet 1121 to the water outlet 1131, the water flow is polarized by the polarization member 121, thereby forming ions that are not easy to precipitate. 1 to the water outlet 1131 are arranged in sequence at intervals, and each polarization component 121 is arranged at an angle, so that the water flow changes its flow direction when flowing through the water outlet 124 between the two adjacent polarization components 121, forming a turbulent flow, thereby increasing the contact area and contact time between the water flow and the polarization component 121, and improving the polarization ionization efficiency; furthermore, since the polarization component 121 of one polarization component 12 of the two adjacent polarization components 12 is inclined in the clockwise direction, and the polarization component 121 of the other polarization component 12 is inclined in the counterclockwise direction, it is easy for the water flow to form a vortex when passing through one polarization component 12 to pass through the other polarization component 12, thereby increasing the turbulent flow effect on the water flow, thereby further enhancing the polarization ionization effect on the water flow.

[0055] It is worth noting that the polarization component 121 is made of catalytic alloy, and the catalytic alloy shell continuously releases free electrons into the water, thereby preventing the aggregation of scale anions such as carbonate and bicarbonate in the water and cations such as calcium and magnesium, thereby achieving scale inhibition of the water body.

[0056] It is further explained that "the polarization component 121 is tilted in the clockwise direction" means that the polarization component 121 is tilted clockwise along the circumference of the polarization element 12 from the side close to the water inlet 1121 to the side away from the water outlet 1131, and the polarization component 121 is tilted in the clockwise direction. "The polarization component 121 is tilted in the counterclockwise direction" means that the polarization component 121 is tilted counterclockwise along the circumference of the polarization element 12 from the side close to the water inlet 1121 to the side away from the water outlet 1131. The clockwise direction refers to the direction toward the water inlet 1121 or the water outlet 1131 when viewed along the preset axis, and the counterclockwise direction is opposite to the clockwise direction.

[0057] The outer contour of the polarization element 12 is adapted to the cross-sectional shape of the water-containing chamber 115, so as to facilitate the stable installation of the polarization element 12 in the water-containing chamber 115, and enable multiple polarization elements 12 to separate the water-containing chamber 115 into multiple sub-water chambers, and the water flow can basically only flow between two adjacent sub-water chambers through the water outlet 124, thereby increasing the contact area between the water flow and the polarization element 12.

[0058] like Figure 2 and Figure 6 As shown, in one embodiment, the cross-section of the water-containing chamber 115 is circular, and the predetermined axis passes perpendicularly through the circular cross-section where the polarizer 12 is located. This allows the polarizer 12 to be configured as a disc-shaped structure that fits the water-containing chamber 115. This facilitates the arrangement of multiple polarizer components 121 on the polarizer 12 and simplifies the structural configuration of the polarizer 12. In other embodiments, the cross-section of the water-containing chamber 115 may also be elliptical, rectangular, or other shapes.

[0059] In one embodiment, the housing 11 extends along a first direction, with the water inlet 1121 and the water outlet 1131 disposed at opposite ends of the housing 11 along the first direction, and a predetermined axis extending along the first direction. This allows the housing 11 to assume a long, strip-like structure arranged along the first direction, resulting in a more streamlined appearance. Specifically, multiple polarizers 12 are spaced apart along the first direction, with the predetermined axes of all polarizers 12 aligned. This simplifies the structure of the housing 11 and improves the ease of placement of the polarizers 12 within the housing 11.

[0060] In other embodiments, the housing 11 may be an elongated structure having an arcuate, zigzag, or other shape, with the water inlet 1121 and the water outlet 1131 disposed at opposite ends of the elongated structure. Multiple polarizers 12 may be disposed at intervals along the extension of the elongated structure. In this arrangement, each polarizer 12 has a different preset axis, and the preset axis of each polarizer 12 is perpendicular to the mounting plane of the polarizer 12.

[0061] Assuming that the plane perpendicular to the preset axis is the flow plane, in order to further simplify the setting of the polarizer 12, in one embodiment, the angle between the polarization component 121 and the flow plane is defined as the preset angle. In the same polarizer 12, the preset angles of all polarization components 121 are the same, thereby making the arrangement of the polarization components 121 on the polarizer 12 consistent, which is conducive to the processing of the polarizer 12.

[0062] like Figures 3 to 5 As shown, further, the preset angles of all polarizers 12 are the same, that is, among two adjacent polarizers 12, only the tilt directions of the polarization components 121 of the two polarizers 12 are different, and the tilt angles are the same.

[0063] The polarization component 121 has two flow-guiding surfaces 1211 spaced apart from each other and arranged in a predetermined axial direction. Both flow-guiding surfaces 1211 are inclined relative to the flow plane, and the angles of inclination between the two flow-guiding surfaces 1211 and the flow plane are substantially the same. This ensures that the polarization component 121 is tilted relative to the flow plane as a whole, facilitating the processing of the polarization component 121. In one embodiment, the flow-guiding surfaces 1211 are smooth curved surfaces; in other embodiments, the flow-guiding surfaces 1211 may alternatively be straight, inclined surfaces.

[0064] In one embodiment, the inclination angle of the polarization component 121 relative to the flow plane is 25° to 60°, thereby avoiding the loss of the flow disturbance due to the inclination angle being too large, and also avoiding the backflow problem of the water due to the inclination angle being too small.

[0065] It is worth noting that when the drainage surface 1211 is a slope, the inclination angle is the angle between the slope and the flow plane; when the drainage surface 1211 is a smooth curved surface, the inclination angle of the polarization component 121 relative to the flow plane is the angle between the plane passing through the two ends of the inclination direction of the drainage surface 1211 and the flow plane.

[0066] The polarization components 121 are preferably arranged in multiple pieces at even intervals around a preset axis. The number of polarization components 121 is preferably 100-1000. In order to avoid the problem of high resistance when water flows through the polarization components 12, the number of polarization components 121 is increased, thereby increasing the contact area between the polarization components 121 and the water flow. The number of polarization components 12 is preferably 100-1000. It is worth noting that the number of polarization components 12 can be adaptively set according to the length of the water treatment device 1, and the number of polarization components 121 on a single polarization component 12 can be adaptively set according to the cross-sectional size of the water containing chamber 115. The present invention does not impose specific restrictions on this.

[0067] To improve the installation convenience and stability of the polarizer 12 in the water-containing chamber 115, a mounting groove 116 is formed on the wall of the water-containing chamber 115. The mounting grooves 116 are arranged in a one-to-one correspondence with the polarizer 12, and the periphery of the polarizer 12 is inserted into the mounting grooves 116. Therefore, by installing the periphery of the polarizer 12 in the mounting grooves 116, the polarizer 12 is restricted from shaking in the first direction in the water-containing chamber 115, thereby improving the installation stability of the polarizer 12 in the water-containing chamber 115.

[0068] In one embodiment, multiple rib groups are formed on the wall of the water-containing chamber 115, corresponding one-to-one with the polarizers 12. Each rib group includes two opposing and spaced rib portions 114, with a mounting groove 116 formed between the two rib portions 114. This arrangement eliminates the need for thinning the main cylinder 111 to create the mounting groove 116. Furthermore, the provision of the rib portions 114 enhances the overall structural strength and rigidity of the housing 11, improving the structural stability of the housing 11 and thereby enhancing the reliability of the water treatment device 1.

[0069] To facilitate installation of the polarizer 12, it includes a coaxially arranged central disk portion 122 and a mounting ring portion 123. Polarization components 121 are connected between the central disk portion 122 and the mounting ring portion 123, and multiple polarization components 121 are spaced apart along the circumference of the central disk portion 122. The mounting ring portion 123 is mounted on the inner wall of the housing 11. This arrangement facilitates the mating of the polarizer 12 with the housing 11 through the mounting ring portion 123, while ensuring the overall structural strength and rigidity of the polarizer 12.

[0070] The core disk portion 122, polarization component 121, and mounting ring portion 123 are integrally formed to better ensure the overall structural strength and rigidity of the polarization component 12, preventing damage to the polarization component 12 from the impact of water flow. This configuration also allows the core disk portion 122 to polarize and ionize substances in the water, thereby enhancing the polarization and ionization effect of the polarization component 12 on substances in the water and improving the scale inhibition effect of the water treatment device 1. In other embodiments, the polarization component 121 may be welded to the core disk portion 122 and / or the mounting ring portion 123 or be detachably connected.

[0071] like Figure 6 and Figure 7 As shown, in one embodiment, the housing 11 includes a main cylinder 111, the interior of which forms a water-containing chamber 115. The cross-section of the housing 11 is circular to facilitate the processing and forming of the housing 11. In other embodiments, the cross-section of the housing 11 may be rectangular, elliptical, or other shapes, as long as the polarization assembly can be installed within the housing 11.

[0072] In order to improve the installation convenience of the water treatment device 1 on the pipeline, a water inlet pipe portion 112 is provided at one end of the main cylinder 111. The inner cavity of the water inlet pipe portion 112 is connected to the water holding chamber 115, and the end of the water inlet pipe portion 112 forms a water inlet 1121. A water outlet pipe portion 113 is provided at the other end of the main cylinder 111. The inner cavity of the water outlet pipe portion 113 is connected to the water holding chamber 115, and the end of the water outlet pipe portion 113 forms a water outlet 1131. The water inlet pipe portion 112 and the water outlet pipe portion 113 are used to connect with the external pipeline to facilitate the installation convenience of the water treatment device 1. The water inlet pipe portion 112 and the water outlet pipe portion 113 can be connected to the external pipeline by threaded connection, interference fit, sealed clamping or other connection methods, which are not limited in this embodiment.

[0073] In order to improve the convenience of disassembly and assembly of the polarizer 12 inside the shell 11, in one embodiment, the shell 11 includes two half shells that are relatively fastened together, and the two half shells together form a water-containing chamber 115, and each polarizer 12 is clamped between the two half shells. In this way, the polarizer 12 can be disassembled and assembled inside the water-containing chamber 115 by disassembly and assembly between the two half shells. Furthermore, a sealing ring is provided at the fastening surfaces of the two half shells to seal the connection between the two half shells. The two half shells are preferably, but not limited to, connected by screws to ensure the stability of the connection. In another embodiment, the shell 11 includes a detachably connected mounting tube and an end cover, at least one end of the mounting tube is open, and the end cover is installed at the open end of the mounting tube, and the polarizer 12 is installed in the mounting tube. Under this arrangement, by disassembling the end cover from the mounting tube, at least one end of the mounting tube is opened, thereby installing the polarizer 12 inside the mounting tube.

[0074] In one embodiment, two water inlets 1121 are provided, namely a first water inlet 1121a and a second water inlet 1121b, thereby increasing the number of water inlet pipes that can be connected to the water treatment device 1. Two water outlets 1131 are provided, namely a first water outlet 1131a and a second water outlet 1131b, thereby increasing the outlet path of water flowing out of the water treatment device 1 and improving the ease of use of the water treatment device 1. It is understood that in other embodiments, the number of water inlets 1121 and water outlets 1131 can be set as needed.

[0075] In one embodiment, the main cylinder 111 comprises two interlocking half-cylinders 111a. Each half-cylinder 111a is provided with an inlet pipe 112 and an outlet pipe 113 at either end. Each half-cylinder 111a and its respective inlet pipe 112 and outlet pipe 113 form a half-shell. This ensures that the structures of the two half-cylinders 111a are substantially identical, facilitating their versatility and reducing the difficulty of manufacturing them. Furthermore, the half-cylinders 111a are semi-cylindrical in shape.

[0076] To further increase the contact area between the water flow and the polarizer 12, in one embodiment, the projections of the polarization components 121 of two adjacent polarizers 12 on the flow plane are staggered along a predetermined direction. As a result, when water flows from one polarizer 12 to the other, at least a portion of the water flow directly impacts the polarization component 121 of the adjacent polarizer 12, thereby disrupting and directing the water flow. This further increases the contact area between the water flow and the polarizer 12, enhancing the polarization ionization effect of the polarizer 12 on the water flow.

[0077] Example 2

[0078] This embodiment provides a water treatment device 1, which adopts the principle of ion polarization scale inhibition to reduce the probability of precipitation of substances in the water flowing through the water treatment device 1, thereby reducing the probability of scale generation. At the same time, there is no need to frequently repair and replace the water treatment device 1, thereby improving the ease of use of the water treatment device 1.

[0079] Specifically, the water treatment device 1 of this embodiment includes a shell 11 and a polarization element 12. The shell 11 has a water containing chamber 115, a water inlet 1121 and a water outlet 1131. The water inlet 1121 and the water outlet 1131 are both connected to the water containing chamber 115. The polarization element 12 is located in the water containing chamber 115 and multiple polarization elements 12 are arranged in sequence from the water inlet 1121 to the water outlet 1131; the polarization element 12 includes multiple polarization components 121 that are relatively and spaced apart, and each polarization component 121 has an inclination angle relative to the flow surface where the polarization element 12 is located, and the inclination angles corresponding to two adjacent polarization elements 12 are different.

[0080] That is, the difference between this embodiment and the above embodiments is that in this embodiment, the multiple polarization components 121 on one polarization element 12 are arranged opposite to each other and spaced apart along a straight line.

[0081] In the water treatment device 1 provided in this embodiment, the polarization components 121 of the two polarization elements 12 have different tilt angles. This causes the water flow to change direction when it flows out of one polarization element 12 and passes between two adjacent polarization components 121 of the other polarization element 12. This increases the polarization element 12's effect on the water flow, prolongs the contact time between the water flow and the polarization components 121, and thus improves the polarization effect of the polarization element 12 on the water flow. To reduce the difficulty of manufacturing the polarization elements 12, in this embodiment, the tilt angles and opening orientations of all polarization components 121 in the same polarization element 12 are the same.

[0082] To enhance the flow disturbance effect, the openings of the polarizers 12 with different angles face opposite directions. This significantly alters the direction of water flowing through the two polarizers 12, facilitating the formation of eddies. Furthermore, the angles corresponding to adjacent polarizers 12 are the same, reducing the difficulty of manufacturing the polarizers 12. Furthermore, the angles are between 25° and 60°.

[0083] In other embodiments, the inclined angles corresponding to two adjacent water polarization elements 12 may have the same opening direction, but different sizes of the inclined angles.

[0084] Furthermore, the polarization component 121 includes a mounting frame, and opposite ends of the polarization component 121 are mounted on the mounting frame, and the mounting frame is mounted on the housing 11 to facilitate the installation of the polarization component 121 on the housing 11.

[0085] It is worth noting that in this embodiment, the cross section of the water chamber 115 is preferably a rectangular cross section, and the polarizer 12 is preferably a rectangular structure. However, in other embodiments, the cross section of the water chamber 115 may be circular or have other structures.

[0086] The specific structure of the housing 11 and the mounting structure of the polarizer 12 on the housing 11 can be set with reference to the first embodiment, and will not be described in detail in this embodiment.

[0087] Example 3

[0088] like Figure 8 As shown, this embodiment provides a water heating device to reduce the probability of scaling of the pipes in the water heater 100 and improve the safety and reliability of the water heater 100.

[0089] In this embodiment, the water heater 100 includes a heating body 2, a cold water inlet pipe 4, a hot water outlet pipe 5, and the aforementioned water treatment device 1. The water inlet of the heating body 2 is connected to the water outlet 1131 via the cold water inlet pipe 4. The water inlet 1121 is connected to the cold water supply pipe 3, which is connected to the cold water supply port 300. The water outlet of the heating body 2 is connected to the water inlet of the hot water outlet pipe 5, and the water outlet of the hot water outlet pipe 5 is connected to the domestic water port 400. The domestic water port 400 can be, but is not limited to, a bathroom water port, a faucet water port, etc.

[0090] The water heater 100 provided in this embodiment connects the water treatment device 1 in series between the cold water supply pipe 3 and the cold water inlet pipe 4, so that tap water needs to flow through the water treatment device 1 before flowing to the heating body 2. When the tap water flows through the water treatment device 1, elements such as iron, manganese, calcium, and magnesium ions therein are converted into ionic states that are not easy to precipitate, thereby reducing the probability of scale formation, and further reducing the probability of scale clogging the water heater 100 pipeline, improving the reliability of the water heater 100, and extending the service life of the water heater 100; at the same time, because the water treatment device 1 adopts polarization ionization to convert substances in the water into ions that are not easy to precipitate, rather than precipitating or filtering the substances in the water, there will be no accumulation of substances in the water treatment device 1, so there is no need to replace or clean the water treatment device 1 regularly, thereby improving the convenience of users using the water heater 100.

[0091] In one embodiment, the water heater 100 is a gas water heater, and the heating element 2 is a heat exchanger. In another embodiment, the water heater 100 may be an electric water heater, and the heating element 2 is an inner tank. In another embodiment, the water heater 100 may also be another type of water heater, such as a solar water heater.

[0092] In one embodiment, the housing 11 of the water treatment device 1 is detachably connected to both the cold water supply pipe 3 and the cold water inlet pipe 4, thereby facilitating the assembly, disassembly, and maintenance of the water treatment device 1 and the water heater 100. In other embodiments, the housing 11 is welded to the cold water supply pipe 3 and / or the cold water inlet pipe 4.

[0093] To further improve the performance of the water heater 100, in one embodiment, the water heater 100 includes a return pipe 6, the water inlet end of the return pipe 6 being connected to the hot water outlet pipe 5, and the water outlet end of the return pipe 6 being connected to the water inlet 1121 of the water treatment device 1 or the cold water supply pipe 3. A return control valve 7 is provided on the return pipe 6. Therefore, when it is necessary to preheat or prevent freezing of water in the pipeline of the water heater 100, the water treatment device 1, the cold water inlet pipe 4, the heating body 2, the hot water outlet pipe 5, and the return pipe 6 can be connected in sequence to form a return water circulation pipeline. As the water circulates within the return water circulation pipeline, it is heated by the heating body 2, thereby achieving preheating, heat preservation, or antifreezing of the water in the pipeline of the water heater 100, realizing a zero cold water setting of the water heater 100, and improving the performance of the water heater 100.

[0094] In one embodiment, the connection between the water inlet end of the return pipe 6 and the hot water outlet pipe 5 is located outside the water heater housing and near the domestic water port 400. This arrangement allows most of the water in the hot water outlet pipe 5 to flow back through the return pipe 6 to the heating body 2 for reheating, reducing the amount of cold water in the hot water outlet pipe 5 and better achieving the zero cold water effect. In other embodiments, the connection between the water inlet end of the return pipe 6 and the hot water outlet pipe 5 can also be located inside the housing.

[0095] In order to prevent the water in the cold water inlet pipe 4 from flowing back to the hot water outlet pipe 5 through the return pipe 6, in one embodiment, a return water one-way valve 8 is also provided on the return water pipe 6. The return water one-way valve 8 only allows the water in the return water pipe 6 to flow through the return water one-way valve 8 to the water treatment device 1, thereby ensuring that the water in the cold water inlet pipe 4 or the water treatment device 1 will not flow back to the hot water outlet pipe 5 through the return water pipe 6.

[0096] Furthermore, a driving water pump 10 is provided on the cold water inlet pipe 4. When the return water control valve 7 is disconnected and the driving water pump 10 is running, cold water sequentially passes through the cold water supply pipe 3, the water treatment device 1, and the cold water inlet pipe 4 and enters the heating body 2 to be heated. When the return water control valve 7 is disconnected, the return water circulation pipeline is opened, and the water in the return water circulation pipeline can circulate under the driving action of the driving water pump 10. This can reduce the number of driving water pumps 10 in the water heater 100, simplify the structure, and reduce the driving cost.

[0097] A flow sensor 9 is also provided on the cold water inlet pipe 4 to detect the cold water inlet flow rate. The water heater 100 includes a controller, and the flow sensor 9 is communicatively connected to the controller. In one embodiment, the flow sensor 9 is provided on the cold water inlet pipe 4. In another embodiment, the flow sensor 9 is provided on the cold water supply pipe 3.

[0098] Example 4

[0099] This embodiment provides a purified drinking water hot water device, which can not only provide hot water for domestic use, but also provide purified drinking water, thereby meeting the user's water needs in many aspects and improving the user's water use experience.

[0100] like Figure 9 As shown, the drinking water hot water purification device provided in this embodiment includes a water heater 100 and a water purification module 200. The water purification module 200 includes a filter device 201 having a filter element, a raw water inlet, a concentrated water outlet, and a pure water outlet. The raw water inlet is connected to the water outlet 1131 of the water treatment device 1 via a filtered water inlet pipe 202; the concentrated water outlet is connected to the water inlet 1121 of the water treatment device 1 via a concentrated water pipe 205. The pure water outlet is connected to a pure water pipe 207, which is connected to the purified drinking water supply end.

[0101] The drinking water hot water purification device provided in this embodiment connects the water inlet end of the filter water inlet pipe 202 to the water outlet 1131 of the water treatment device 1, so that the water that has been polarized by the water treatment device 1 can flow into the filter device 201 through the filter water inlet pipe 202, thereby reducing the precipitation of substances in the filter water inlet pipe 202 and the probability of the filter water inlet pipe 202 being blocked. At the same time, the water heater 100 and the water purification module 200 can share the cold water supply pipe 3 for water intake, thereby simplifying the overall pipeline layout of the drinking water hot water purification device and reducing costs. The water pipe 205 is connected to the water inlet 1121 of the water treatment device 1, so that the concentrated water generated after filtration by the filter device 201 can be recycled into the water treatment device 1 and mixed and diluted with the cold water flowing into the water holding chamber 115 from the cold water supply pipe 3 in the water holding chamber 115 of the water treatment device 1. The mixed and diluted water can also be polarized by the polarization component 121 and converted into an ionic state that is not easy to precipitate, and then flow into the filter device 201 or the water heater 100 again, avoiding the waste caused by direct discharge of the concentrated water generated by the filter device 201, saving water resources and reducing costs.

[0102] In one embodiment, the filter element of the filter device 201 is a composite reverse osmosis filter element, which has good filtering effect and high filtering efficiency. The filter device 201 with a composite filter element is a mature product and this embodiment does not limit its structure. In this embodiment, the filter element of the filter device 201 can also be other types of existing filter structures.

[0103] In one embodiment, the water treatment device 1 includes two water inlets 1121 and two water outlets 1131, the two water inlets 1121 are respectively a first water inlet 1121a and a second water inlet 1121b, the two water outlets 1131 are respectively a first water outlet 1131a and a second water outlet 1131b, the outlet end of the cold water supply pipe 3 is connected to the first water inlet 1121a, the outlet end of the concentrated water pipe 205 is connected to the second water inlet 1121b, the inlet end of the cold water inlet pipe 4 is connected to the first water outlet 1131a, and the inlet end of the filter inlet pipe 202 is connected to the second water outlet 1131b. This setting can separate the water inlet of the concentrate pipe 205 to the water treatment device 1 from the water inlet of the cold water supply pipe 3 to the water treatment device 1, effectively preventing the concentrate discharged from the concentrate pipe 205 from flowing to the cold water supply pipe 3, and making it possible to disassemble and assemble the water treatment device 1, the cold water supply pipe 3 and the concentrate pipe 205 separately; by setting the first water outlet 1131a and the second water outlet 1131b, it is convenient to realize the separate connection between the cold water inlet pipe 4, the filter inlet pipe 202 and the water treatment device 1, thereby improving the convenience of use.

[0104] In another embodiment, only one water inlet 1121 may be provided, i.e., the outlet of the concentrate pipe 205, the water treatment device 1, and the cold water supply pipe 3 are connected via a tee. In another embodiment, only one water outlet 1131 may be provided, i.e., the outlet 1131 of the water treatment device 1, the inlet of the cold water inlet pipe 4, and the inlet of the filtered water inlet pipe 202 are connected via a tee.

[0105] In one embodiment, a drain control valve 206 is provided on the concentrate pipe 205 to control the concentrating flow of the concentrate pipe 205, thereby facilitating maintenance of the water purification module 200 and water heater 100. The concentrate pipe 205 can be connected to the water inlet pipe portion 112 of the water treatment device 1 using, but not limited to, a removable and sealed connection such as a threaded connection or an interference fit, to enhance the ease of assembly, disassembly, and maintenance of the purified hot water device.

[0106] Furthermore, a booster pump 204 and an inlet control valve 203 are installed on the filter water inlet pipe 202. The booster pump 204 is used to increase the water pressure flowing to the filter device 201, thereby increasing the pressure of the water impacting the filter membrane and improving the osmotic filtration effect. The inlet control valve 203 is used to control the on / off state of the filter water inlet pipe 202, thereby controlling the water intake and filtration performance of the filter device 201. Both the inlet control valve 203 and the booster pump 204 are communicatively connected to the controller.

[0107] In one embodiment, the purified drinking water supply includes a hot water purified drinking water port 230 and a normal temperature purified drinking water port 220. The pure water pipe 207 includes a pure water main pipe 2071, a first branch pipe 2072, and a second branch pipe 2073. The water inlet of the pure water main pipe 2071 is connected to the pure water outlet of the filtration device 201, and the first branch pipe 2072 is connected between the pure water main pipe 2071 and the normal temperature purified drinking water port 220. The water purification module 200 also includes a connecting pipe 210 and a heating assembly 219 disposed on the connecting pipe 210. The second branch pipe 2073 is connected between the connecting pipe 210 and the water outlet of the pure water main pipe 2071. The connecting pipe 210 is connected between the hot water purified drinking water port 230 and the water outlet of the second branch pipe 2073. The heating assembly 219 is used to heat the water flowing through it. This configuration can meet the needs of both normal temperature drinking water and hot drinking water, improving the user experience of the purified drinking water device.

[0108] In one embodiment, the water purification module 200 further includes a water divider 211 having a first inlet, a second inlet, a first outlet, and a second outlet. The water divider 211 further includes a first channel connecting the first outlet and the first inlet, a second channel connecting the second inlet and the second outlet, and a third channel connecting the second inlet and the first outlet. The first channel is connected in series to the filtered water inlet pipe 202, and the second channel is connected in series between the second branch pipe 2073 and the connecting pipe 210. The third channel is provided with a diverter check valve that only allows water to flow from the second inlet to the first outlet.

[0109] By providing a water divider 211, the first channel, the filtered water inlet pipe 202, the filter device 201, the pure water main pipe 2071, the second branch pipe 2073, and the third channel are sequentially connected to form a filtration circulation pipeline. When the hot water purification end 230 is opened, the pure water produced by the filter device 201 flows into the water divider 211 through the pure water main pipe 2071 and the second branch pipe 2073. A portion of the pure water then flows to the hot water purification end 230 through the second outlet, while the remaining portion flows back to the filter device 201 through the third channel and the filtered water inlet pipe 202 for further filtration. The water divider 211 can thus change the pressure and flow rate of the water flowing to the hot water purification end 230, ensuring that the flow rate and pressure of the water flowing through the heating assembly 219 meet the power requirements of the heating assembly 219, thereby avoiding water pressure fluctuations at the hot water purification end 230 and improving the water output stability of the hot water purification end 230.

[0110] Furthermore, a pure water check valve 208 is provided on the pure water main pipe 2071. This check valve 208 only allows water to flow from the pure water outlet to the outlet end of the pure water main pipe 2071. The provision of the pure water check valve 208 prevents the pure water from flowing back into the filter device 201. Furthermore, a pressure switch 209 is provided on the pure water pipe 207, located downstream of the pure water check valve 208.

[0111] An auxiliary water pump 214 is provided on the connecting pipe 210, and the auxiliary water pump 214 is communicatively connected to the controller. The auxiliary water pump 214 can avoid the problem of insufficient water supply pressure caused by the long pipeline between the pure water outlet and the hot water drinking water end 230, and ensure the water supply pressure of the hot water drinking water end 230.

[0112] Furthermore, connecting pipe 210 is equipped with a heating control valve 212, which is used to control the opening and closing of connecting pipe 210, thereby preventing hot water from flowing out of hot water purification port 230 and causing burns to the user. Connecting pipe 210 is also equipped with a zero-pressure valve 213 to ensure that the rear water channel of connecting pipe 210 is pressure-free when supplying water, thereby better controlling the water flow rate and outlet water temperature. Zero-pressure valve 213 is located between heating control valve 212 and auxiliary water pump 214.

[0113] The connecting pipe 210 is also equipped with an inlet flowmeter 215 to detect the flow rate in the connecting pipe 210, thereby better regulating the heating power of the heating assembly 219, ensuring that the outlet water temperature of the hot water purification drinking water terminal 230 meets the required temperature and preventing the water temperature at the hot water purification drinking water terminal 230 from being overheated or underheated. The connecting pipe 210 is also equipped with an inlet water temperature sensor to detect the temperature of the water flowing into the heating assembly 219, thereby regulating the heating efficiency of the heating assembly 219. The inlet water temperature sensor and the inlet water flow sensor are both communicatively connected to the controller.

[0114] Connecting pipe 210 is also provided with a water outlet thermometer 217, which is located downstream of heating assembly 219. This thermometer detects the temperature of the water heated by heating assembly 219, thereby determining whether the temperature of the water flowing out of heating assembly 219 meets the target temperature requirement. The thermometer is in communication with the controller.

[0115] The heating assembly 219 includes an electric heating pipe, and the connecting pipe 210 can be set using an existing structure. The capacity and heating power of the connecting pipe 210 can be set according to needs, and this embodiment does not impose any restrictions on this.

[0116] Furthermore, a water vapor separator 218 is provided on the connecting pipe 210. The water vapor separator 218 is arranged downstream of the heating component 219. The water vapor separator 218 has a water vapor inlet, a liquid outlet and a gas outlet. The water vapor inlet is connected to the water outlet end of the heating component 219, the liquid outlet is connected to the hot water supply end, and the gas outlet is connected to the external environment. Thus, gas-liquid separation is achieved through the water vapor separator 218, which prevents water vapor from flowing out through the hot water supply end and scalding the user, thereby improving the safety and reliability of the water purification module 200 and the drinking water purification equipment.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described.
