Description

Technical Field

[0001] This utility model relates to the field of water purification, and in particular to a filtration device and a water purifier containing the same. Background Technology

[0002] With increasing health awareness and growing concern about water quality, water purifiers have become indispensable household appliances in modern homes. They are not only found in kitchens but are also becoming increasingly common in offices, schools, and public places. Water purifiers, with their ability to efficiently remove impurities, bacteria, and heavy metals from water, ensure that every drop of water we drink is pure and safe. With technological advancements, water purifiers have become more intelligent and convenient, automatically adjusting their filtration programs based on water quality and usage habits to meet the needs of different groups.

[0003] During water purification, resin tanks are used to replace calcium and magnesium ions (i.e., hardness ions) in the water with sodium ions through ion exchange, thereby reducing water hardness. Once the resin in the tank has adsorbed a certain amount of hardness ions, it needs a regeneration process to restore its exchange capacity. During this process, brine in the salt tank is used to rinse the resin layer, and the sodium ions in the brine displace the hardness ions from the resin. Currently, tap water is commonly used to dissolve the salt in the salt tank. However, because tap water is cold and contains organic matter or impurities that interact with the salt, the dissolution rate of the salt in the salt tank is affected, leading to a longer resin regeneration cycle and a reduced water softening capacity of the resin. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing technology in terms of increasing the regeneration cycle of resin due to the temperature of tap water or organic matter or impurities in tap water, and to provide a filtration device and a water purifier containing the same.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This utility model discloses a filtration device, which includes a water purification module, a heating module, a salt tank, and a resin tank. The water purification module, the heating module, the salt tank, and the resin tank are connected in sequence. The salt tank contains salt, the resin tank is used to soften water, the water purification module is connected to a water source, the water purification module is used to purify water quality, and the heating module is used to heat the purified water.

[0007] The heating module is used to heat water to 40 to 75 degrees Celsius.

[0008] In this solution, the purified water is heated by a heating module to maintain its temperature between 40 and 75 degrees Celsius. When the heated water enters the brine tank, it accelerates the dissolution rate of the salt. Furthermore, the purification process removes organic matter and impurities from the water. Therefore, using purified water to dissolve the salt in the brine tank prevents organic matter or impurities from interacting with the salt and increasing the saturation concentration of the molten salt. With this structural design, the faster dissolution rate of the salt in the brine tank improves the efficiency of brine entering the resin tank, thereby increasing the efficiency of brine rinsing the resin layer and reducing the resin regeneration cycle.

[0009] Preferably, the filtration device further includes a temperature detection module and a first connecting pipe, the first connecting pipe connecting the heating module and the salt tank, and the temperature detection module being disposed on the first connecting pipe for detecting the temperature inside the first connecting pipe.

[0010] In this solution, the above-mentioned structure is adopted, and the temperature detection module monitors the water temperature of the first connecting pipe in real time, thereby ensuring that the temperature entering the salt tank meets the preset requirements and improving the accuracy of temperature control.

[0011] Preferably, the filtration device further includes a water supply valve, which is located between the heating module and the salt tank, and is used to control the connection or disconnection of the heating module and the salt tank.

[0012] In this solution, the above-mentioned structural form is adopted, which improves the controllability of whether the heating module and the salt tank are connected.

[0013] Preferably, the filtration device further includes a second connecting pipe, which is connected to the water outlet of the heating module and is used to connect to the first user end.

[0014] In this solution, by adopting the above-mentioned structural form, the water heated by the heating module can be supplied to the first user end through the second connecting pipe, thereby meeting the water demand of the first user end.

[0015] Preferably, the water purification module includes a coarse filter element, a pre-filter element, an RO / NF filter element, and a post-filter element. The coarse filter element, the pre-filter element, the RO / NF filter element, and the post-filter element are connected in sequence. The inlet end of the coarse filter element is connected to the water source, and the outlet end of the post-filter element is connected to the heating module and the second user end, respectively.

[0016] In this solution, the aforementioned structural design ensures that water undergoes multiple filtration stages for deep purification. Specifically, the coarse filter effectively removes large particulate impurities and suspended solids. The pre-filter removes residual chlorine, and the RO / NF filter efficiently removes bacteria, viruses, heavy metals, and most dissolved solids through reverse osmosis or nanofiltration technology, ensuring the water meets drinking water standards. The post-filter performs final fine treatment on the purified water, further improving its quality and removing any remaining microparticles and odors, ensuring the taste and safety of the output water. The outlet of the post-filter is connected to both the heating module and a second user terminal, allowing the purified water to be directly used for heating or supplied to other users requiring purified water.

[0017] Preferably, the water purification module further includes a sterilization component, the inlet of which is connected to the outlet of the post-filter, and the outlet of which is connected to the heating module and the second user terminal respectively.

[0018] The above-mentioned structure in this solution can eliminate residual bacteria and viruses in the water, ensuring the safety of water use.

[0019] Preferably, the water purification module further includes a third connecting pipe and a booster pump. The third connecting pipe connects the pre-filter and the RO / NF filter. The booster pump is located on the third connecting pipe and is used to pressurize the water flowing in the third connecting pipe.

[0020] In this solution, the above-mentioned structure can pressurize the water flow between the pre-filter and the RO / NF filter, ensuring that the water has sufficient pressure to pass through each filter element, thereby improving the efficiency of water purification.

[0021] Preferably, the filtration device further includes a fourth connecting pipe, which is connected to the water outlet of the coarse filter element and the water inlet of the resin tank, respectively, and the water outlet of the resin tank is connected to a third user end.

[0022] In this solution, the above-mentioned structure is adopted, and the water outlet of the coarse filter element and the water inlet of the resin are connected through the fourth connecting pipe. This allows the water to flow into the resin tank after large particles of impurities are removed by the coarse filter element. The pre-purified water can then enter the softening treatment stage, thereby reducing the hardness of the water through the resin, reducing the formation of scale, and ensuring the water safety of the third user.

[0023] Preferably, the filtration device further includes a motor pump located between the water purification module and the heating module, the motor pump being used to draw water from the water purification module to the heating module.

[0024] In this solution, the above-mentioned structural form is adopted, and the efficiency of water flowing from the water purification module to the heating module is improved by using a motor pump, thereby improving the efficiency of water being heated by the heating module.

[0025] This utility model discloses a water purifier, which includes the filtration device as described in any of the above claims.

[0026] In this solution, the aforementioned structural form is used to apply the filtration device to the water purifier. The purified water is then heated via a heating module, maintaining the water temperature between 40 and 75 degrees Celsius. When the heated water enters the brine tank, it accelerates the dissolution rate of the salt. Furthermore, the purification process removes organic matter and impurities from the water. Therefore, using purified water to dissolve the salt in the brine tank prevents organic matter or impurities from interacting with the salt and increasing the saturated concentration of the molten salt. With this structural form, the faster dissolution rate of the salt in the brine tank improves the efficiency of brine entering the resin tank, thereby increasing the efficiency of brine rinsing the resin layer and reducing the resin regeneration cycle.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] The purified water is heated by a heating module, maintaining its temperature between 40 and 75 degrees Celsius. When this heated water enters the brine tank, it accelerates the dissolution of salt. Furthermore, the purification process removes organic matter and impurities from the water. Therefore, using purified water to dissolve the salt in the tank prevents organic matter or impurities from interacting with the salt and increasing the saturation concentration of the molten salt. This structural design, by accelerating the dissolution of salt in the tank, improves the efficiency of brine entering the resin tank, thereby increasing the efficiency of brine rinsing the resin layer and reducing the resin regeneration cycle.

[0061] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0062] like Figure 1As shown, this embodiment provides a filtration device 100, which includes a water purification module 1, a heating module 2, a salt tank 3, and a resin tank 4. The water purification module 1, heating module 2, salt tank 3, and resin tank 4 are connected in sequence. The salt tank 3 contains salt, and the resin tank 4 is used to soften the water. The water purification module is connected to a water source and is used to purify the water quality. The heating module 2 is used to heat the purified water; specifically, the heating module 2 heats the water to 40 to 75 degrees Celsius. Specifically, by heating the purified water using the heating module 2, the water temperature can be maintained between 40 and 75 degrees Celsius. When the heated water enters the salt tank 3, it can accelerate the dissolution rate of the salt in the salt tank 3. Furthermore, water purification removes organic matter and impurities from the water. Therefore, using purified water to dissolve the salt in the salt tank 3 can prevent organic matter or impurities from interacting with the salt, thus increasing the saturated concentration of the molten salt. By adopting the above-described structure, when the salt dissolution rate in the salt tank 3 increases, the efficiency of brine entering the resin tank 4 can be improved, thereby increasing the efficiency of brine rinsing the resin layer and reducing the resin regeneration cycle.

[0063] The filtration device 100 also includes a temperature detection module 5 and a first connecting pipe 6. The first connecting pipe 6 connects the heating module 2 and the salt tank 3. The temperature detection module 5 is mounted on the first connecting pipe 6 and is used to detect the temperature inside the first connecting pipe 6. With the above structure, the temperature detection module 5 monitors the water temperature in the first connecting pipe 6 in real time, thereby ensuring that the temperature entering the salt tank 3 meets the preset requirements and improving the accuracy of temperature control.

[0064] In this embodiment, the temperature detection module 5 is a temperature probe. In other embodiments, it may be other forms of temperature detection module 5, which are not limited here.

[0065] The filtration device 100 also includes a water supply valve 7, which is located between the heating module 2 and the salt tank 3. The water supply valve 7 is used to control the connection or disconnection between the heating module 2 and the salt tank 3, thereby improving the controllability of whether the heating module 2 and the salt tank 3 are connected.

[0066] It should be noted that, in actual use, the water supply valve 7 can also be used to control the flow rate of water from the heating module 2 to the salt tank 3, thereby controlling the efficiency of water flowing from the heating module 2 to the salt tank 3 according to the water level in the salt tank 3.

[0067] The filtration device 100 also includes a second connecting pipe 8, which is connected to the water outlet of the heating module 2 and is used to connect to the first user terminal. With this structure, the water heated by the heating module 2 can be supplied to the first user terminal through the second connecting pipe 8, thereby meeting the water demand of the first user terminal.

[0068] Specifically, the water heated by the heating module 2 can enter the salt tank 3 to dissolve the salt in the salt tank 3, or it can be supplied to the first user terminal through the second connecting pipe 8. In addition, a hot water drain valve 20 is provided between the heating module 2 and the first user terminal, thereby realizing the controllability of whether the heating module 2 and the first user terminal are connected.

[0069] The water purification module 1 includes a coarse filter element 11, a pre-filter element 12, an RO / NF filter element 13, and a post-filter element 14. These elements are connected sequentially. The inlet of the coarse filter element 11 is connected to the water source, and the outlet of the post-filter element 14 is connected to the heating module 2 and the second user terminal, respectively. This structure ensures that the water undergoes multiple filtration stages for deep purification. Specifically, the coarse filter element 11 effectively removes large particulate impurities and suspended solids from the water. The pre-filter element 12 removes residual chlorine, and the RO / NF filter element 13 efficiently removes bacteria, viruses, heavy metals, and most dissolved solids through reverse osmosis or nanofiltration technology, ensuring the water quality meets drinking standards. The post-filter element 14 performs final fine treatment on the purified water, further improving water quality and removing any remaining small particles and odors, ensuring the taste and safety of the output water. The outlet of the post-filter 14 is connected to the heating module 2 and the second user terminal, respectively, so that the purified water can be directly used for heating or supplied to other users who need pure water.

[0070] In addition, a purification module inlet valve 21 is provided between the coarse filter element 11 and the pre-filter element 12, and the connection or closure between the coarse filter element 11 and the pre-filter element 12 is controlled by the purification module inlet valve 21.

[0071] The water purification module 1 also includes a sterilization component 15, the inlet of which is connected to the outlet of the post-filter 14, and the outlet of which is connected to the heating module 2 and the second user terminal. This structure effectively eliminates residual bacteria and viruses in the water, ensuring water safety.

[0072] In this embodiment, ultraviolet light can be used for sterilization. In other embodiments, the sterilization method of the sterilization component 15 can be adjusted according to actual needs, and is not limited here. A room temperature water discharge valve 29 can be provided between the sterilization component 15 and the second user terminal, thereby controlling the controllability of the connection between the sterilization component 15 and the second user terminal. In addition, a first one-way valve 24 is provided between the post-filter 14 and the sterilization component 15, and the first one-way valve 24 allows flow from the post-filter 14 to the sterilization component 15.

[0073] The water purification module 1 also includes a third connecting pipe 16 and a booster pump 17. The third connecting pipe 16 connects the pre-filter 12 and the RO / NF filter 13. The booster pump 17 is installed on the third connecting pipe 16 and is used to pressurize the water flowing through the third connecting pipe 16. This structure can pressurize the water flow between the pre-filter 12 and the RO / NF filter 13, ensuring that the water has sufficient pressure to pass through each filter element, thus improving the efficiency of water purification.

[0074] It should be further explained that the power of heating module 2 remains constant, and closed-loop control can be formed through the temperature detection module 5 and the voltage adjustment of booster pump 17. In other words, by detecting the temperature through temperature detection module 5 and adjusting the pressure of the booster pump, the water flow rate can be adjusted. With a fixed power of heating module 2, the temperature of the water heated by heating module 2 can be changed by changing the water flow rate, so that the water temperature can be maintained between 40 degrees and 75 degrees.

[0075] The filtration device 100 also includes a fourth connecting pipe 9, which is connected to the outlet of the coarse filter element 11 and the inlet of the resin tank 4. The outlet of the resin tank 4 is connected to the third user. With this structure, the fourth connecting pipe 9 connects the outlet of the coarse filter element 11 to the inlet of the resin tank. This allows water, after being filtered to remove large particles by the coarse filter element 11, to flow into the resin tank 4. The pre-purified water then enters the softening stage, where the resin reduces water hardness, minimizes scale formation, and ensures water safety for the third user.

[0076] Additionally, the wastewater produced after filtration by the RO / NF filter element 13 can be discharged through the drain channel 22 or enter the resin tank 4 through the fifth connecting pipe 23. After softening in the resin tank 4, the wastewater is supplied there. A second one-way valve 25 and a third one-way valve 26 are respectively installed on the drain channel 22 and the fifth connecting pipe 23. The second one-way valve 25 connects to the outside from the RO / NF filter element 13, and the third one-way valve 26 connects to the resin tank 4 from the RO / NF filter element 13. A concentrate valve 31 is provided on the drain channel 22, and the concentrate valve 31 is used to control the connection between the RO / NF filter element 13 and the outside.

[0077] The first passage between the coarse filter element 11 and the resin tank 4, the second passage between the salt tank 3 and the resin tank 4, the third passage between the outlet of the resin tank 4 and the third user end, and the fifth connecting pipe 23 can be connected by the multi-channel control valve 30.

[0078] The filtration device 100 also includes a motor pump 10, which is located between the water purification module 1 and the heating module 2. The motor pump 10 is used to draw water from the water purification module 1 to the heating module 2. With the above structure, the efficiency of water flowing from the water purification module 1 to the heating module 2 is improved by the motor pump 10, and the efficiency of water being heated by the heating module 2 is also improved.

[0079] In practical use, the sterilization component 15 is connected to the heating module 2 in sequence through the water valve component 27, the flow meter 28, and the motor pump 10.

[0080] This embodiment also provides a water purifier, which includes a filter device 100. Using the above-described structure, the filter device 100 is applied to the water purifier, thereby heating the purified water via the heating module 2, maintaining the water temperature between 40 and 75 degrees Celsius. When the heated water enters the salt tank 3, it accelerates the dissolution rate of the salt in the salt tank 3. Furthermore, purification removes organic matter and impurities from the water; therefore, using purified water to dissolve the salt in the salt tank 3 avoids the interaction between organic matter or impurities and the salt, thus preventing an increase in the saturated concentration of the molten salt. With this structure, when the salt dissolution rate in the salt tank 3 increases, the efficiency of the brine entering the resin tank 4 is improved, thereby increasing the efficiency of brine rinsing the resin layer and reducing the resin regeneration cycle.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
