Description

Technical Field

[0001] This invention relates to an electrolytic water generating device, and more particularly to an electrolytic water module capable of generating strongly alkaline and strongly acidic electrolytic water. This invention also relates to an electrolytic water platform capable of providing electrolytic water. Background Technology

[0002] Most cleaning appliances on the market currently enhance cleaning effectiveness by directly adding cleaning agents, and further enhance sterilization by adding bactericides. Common cleaning agents and bactericides are composed of a variety of chemical substances, which need to be purchased by users. Different cleaning agents and bactericides are required for different scenarios, which makes it inconvenient for users to purchase, add and store them.

[0003] As is well known, water can be electrolyzed to produce alkaline electrolyzed water and acidic electrolyzed water. Alkaline electrolyzed water has a highly efficient cleaning effect, while acidic electrolyzed water has a bactericidal effect. The effects vary depending on the pH level, making it suitable for various applications. However, common acidic and alkaline electrolyzed water preparation technologies suffer from the following problems:

[0004] First, common electrolytic sterilization modules only produce acidic electrolyzed water: The electrolytic water sterilization modules commonly used in household appliances use diaphragm-less electrolytic cells. Because there is no diaphragm to block it, the alkaline water produced on the cathode plate will neutralize the acidic water produced on the anode plate during electrolysis. It can only produce acidic electrolyzed water for sterilization and does not produce strong alkaline electrolyzed water with cleaning effect. It cannot meet the needs of household sterilization and cleaning at the same time.

[0005] Secondly, common equipment for simultaneously producing acidic and alkaline electrolyzed water suffers from insufficient pH value and limited output: diaphragm electrolyzers separate the cathode and anode chambers with a diaphragm, allowing for the simultaneous electrolysis of acidic and alkaline electrolyzed water after the addition of electrolyte. However, diaphragm electrolyzers often employ flow-through electrolysis, which involves electrolyzing a flowing water / electrolyte solution, immediately discharging alkaline electrolyzed water from the cathode chamber and acidic electrolyzed water from the anode chamber. This method results in a short electrolysis time, insufficient pH value for both alkaline and acidic electrolyzed water, limited output, and limited water volume.

[0006] Third, it can only produce one pH value: different scenarios have different sterilization needs, requiring different pH values ​​of acidic electrolyzed water. Conventional electrolyzers can only produce acidic electrolyzed water of one pH value under one operating condition. Achieving different pH values ​​requires adding more electrolyzers or changing electrolysis parameters, such as voltage, current, and electrolysis time. This is not only costly and complex, but also requires a long waiting time to prepare water with a different pH value, making it unresponsive and unsuitable for meeting the sterilization needs of various household scenarios.

[0007] Fourth, the core components of the electrolyzer are easily clogged by scale and solid impurities, affecting its performance: Scale formed from calcium and magnesium ions in tap water easily adheres to the diaphragm and electrode plates of the electrolyzer's core components, affecting the electrolysis effect and even causing it to fail. Therefore, soft water electrolysis is required. Conventional methods produce the required electrolyzed water through direct electrolysis, requiring a large amount of soft water, resulting in a large soft water module with a limited lifespan. In addition, other solid impurities in the water adhering to the diaphragm and electrode plates will also affect their performance.

[0008] Fifth, the diaphragm, a core component of the electrolyzer, needs to be wetted and protected: the simultaneous preparation of acidic and alkaline electrolyzed water is inseparable from the core component - the diaphragm. The diaphragm is an ion exchange membrane, a special polymer membrane that can selectively allow anions and cations to pass through while isolating alkaline and acidic water generated by the anions and anodes to prevent neutralization. However, the diaphragm will deform and fail if it dries out, so it needs to be kept moist.

[0009] Sixth, the preparation of acidic electrolyzed water produces chlorine gas: Most acidic electrolyzed water preparation uses chloride salts (such as sodium chloride) as electrolytes, which electrolyze to produce bactericidal active ingredients such as hypochlorous acid. However, it also produces harmful byproducts such as chlorine gas. Direct discharge of these byproducts will pollute the environment, harm health, and is not suitable for household use. Summary of the Invention

[0010] The first technical problem to be solved by the present invention is to provide an electrolytic water module with a large water output and less scale buildup on the ion exchange membrane and electrode plates, in light of the above-mentioned technical status.

[0011] The second technical problem to be solved by the present invention is to provide an electrolytic water base station with a large water output and less scale buildup on the ion exchange membrane and electrode plates, in view of the above-mentioned technical status.

[0012] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: an electrolysis water module, characterized in that it includes...

[0013] The outer casing is H-shaped and includes a cathode chamber, an anode chamber, and an electrolysis chamber arranged laterally between the cathode chamber and the anode chamber. The aforementioned cathode chamber and anode chamber are both arranged longitudinally. The aforementioned cathode chamber is used to generate strongly alkaline water and has a first water inlet port and a first water outlet port.

[0018] Furthermore, a first insulating mesh is provided between the anode plate and the cation exchange membrane. A second insulating mesh is provided between the cathode plate and the anion exchange membrane. The insulating mesh serves to protect the ion exchange membrane, accelerate venting, inhibit scale deposition, and accelerate ion transfer.

[0019] The anode chamber has an outlet port, and the electrolysis chamber has an inlet port near the cathode chamber. The water electrolysis module also includes a gas treatment box, whose inlet end is connected to the aforementioned outlet port, and whose outlet end is connected to the aforementioned inlet port. Chlorine gas generated in the anode chamber is introduced into the gas treatment chamber, reacts with alkaline electrolyzed water, and the waste liquid is discharged into the sewer, effectively preventing chlorine gas from being released into the air. Waste liquid will be discharged and alkaline electrolyzed water will be replenished periodically.

[0020] Furthermore, the gas treatment box has an exhaust pipe with a gas valve.

[0021] The height of the first outlet port is level with the highest points of the anion exchange membrane and the cation exchange membrane. A first electronic water level gauge is installed along the height direction in the cathode chamber. A second electronic water level gauge is installed along the height direction in the anode chamber. This arrangement ensures that the cathode chamber always retains a protective wetting solution, preventing the ion exchange membrane from drying out and failing.

[0022] The electrolysis chamber has a circulating brine inlet leading to the salt chamber and a circulating brine outlet leading out of the salt chamber. The brine is replenished through a circulation pipe.

[0023] Preferably, the outer shell includes a first shell, an intermediate shell, and a second shell. The first shell includes a first vertical portion and a first horizontal portion extending laterally from the middle of the first vertical portion. The inner cavity of the first vertical portion forms the cathode chamber. The second shell includes a second vertical portion and a second horizontal portion extending laterally from the middle of the second vertical portion. The inner cavity of the second vertical portion forms the anode chamber. The intermediate shell is sealed between the first horizontal portion and the second horizontal portion. The anion exchange membrane is disposed between the first horizontal portion and the intermediate shell, and the cation exchange membrane is disposed between the second horizontal portion and the intermediate shell.

[0024] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: an electrolysis water base station, characterized in that it includes...

[0025] The water electrolysis module has a second inlet port and a second outlet port.

[0026] The first water inlet pipe is connected to the aforementioned second water inlet port;

[0027] The first water outlet pipe is connected to the aforementioned second water outlet port;

[0028] Branch pipes are connected between the aforementioned first inlet pipe and first outlet pipe; and

[0029] The solenoid valve is used to regulate the flow rate of the aforementioned first inlet pipe and branch pipe.

[0030] Furthermore, a first water pump and a second water pump are respectively installed on the first water outlet pipeline and the branch pipeline.

[0031] Furthermore, the first water inlet port of the electrolytic water module is provided with a second water inlet pipe.

[0032] The solenoid valve can be configured in one of the following two ways:

[0033] The first type of solenoid valve has at least an inlet end, a first outlet end and a second outlet end. The inlet end is connected to soft water, the first outlet end is connected to the second inlet port of the water electrolysis module, and the second outlet end is connected to the branch pipeline.

[0034] The second type includes a first solenoid valve located on the first outlet pipe and a second solenoid valve located on the branch pipe.

[0035] Furthermore, the first water outlet port of the electrolytic water module is provided with a second water outlet pipe, and a third solenoid valve is provided on the second water outlet pipe.

[0036] Furthermore, a third water pump is installed on the second water outlet pipe.

[0037] Compared with the prior art, the advantages of the present invention are as follows:

[0038] The cathode chamber (as the acidic electrolyzed water generation chamber), anode chamber (as the alkaline electrolyzed water generation chamber) / electrolysis chamber, and salt chamber are integrated to form the main structure of the static electrolyzed water module, achieving: 1) generating a large amount of low-pH strongly acidic electrolyzed water (pH≤3) through static electrolysis in the anode chamber; 2) simultaneously generating a large amount of high-pH strongly alkaline electrolyzed water (pH≥11) through static electrolysis in the cathode chamber; 3) the intermediate chamber formed by the anion and cation exchange membranes is the salt chamber, through which a certain concentration of chloride salt solution is circulated. The anions and cations in the salt solution selectively pass through the anion and cation exchange membranes into the anion and anode chambers, respectively, and excess salt solution does not enter the anion and anode chambers, ensuring smooth electrolysis while avoiding excess electrolyte contamination of the electrolyzed water.

[0039] The H-structure design raises the middle electrolytic cell section to form a precipitation protection area at the bottom of the cathode and anode chambers, preventing scale and other solid impurities in the water from adhering to the ion exchange membranes and electrode plates, thus affecting performance and lifespan.

[0040] The H-type static water electrolysis module features a structure where the outlets of the cathode and anode chambers are level with the top of the diaphragm. Combined with an electronic water level gauge for real-time liquid level monitoring, this design maintains the minimum liquid level above the diaphragm and ensures that the cathode and anode chambers always have a bottom liquid to wet the diaphragm, preventing the diaphragm from drying out and failing.

[0041] The gas treatment chamber can use alkaline water electrolysis to treat the chlorine gas generated during the production of acidic water electrolysis, and then discharge it into the sewer, which helps to prevent chlorine gas from being released into the air.

[0042] By designing and controlling a real-time acidic electrolyzed water system, a pre-prepared low-pH, strongly acidic electrolyzed water reserve solution is mixed with another source of tap water. The amounts of both solutions are automatically adjusted to quickly prepare acidic electrolyzed water solutions with different pH values ​​and dosages to meet different sterilization needs in different scenarios.

[0043] The design and control of an automatic replenishment and preparation system for acidic electrolyzed water enables the automatic replenishment and preparation of a low-pH, strongly acidic electrolyzed water reserve solution without user intervention.

[0044] By mixing a pre-prepared low-pH, strongly acidic electrolyzed water stock solution with another source of tap water to prepare acidic electrolyzed water with different pH values ​​and dosages, instead of direct electrolysis, the amount of soft water required for electrolysis is greatly reduced, thereby reducing the volume of the soft water resin and extending its lifespan.

[0045] By precisely configuring acidic electrolyzed water with different pH values, accurately replenishing the target pH electrolyzed water, and preparing it through timed electrolysis, this method is more reliable and less expensive than traditional pH sensor methods. Attached Figure Description

[0053] The first water outlet port 2a of the water electrolysis module 10 is provided with a second water outlet pipe 4b, and a three-way solenoid valve 2c is provided on the first water outlet pipe 2b and connected to the branch pipe 3b.

[0054] Combination Figure 2 and Figure 3 As shown, the water electrolysis module 10 in this embodiment includes a shell 1, an anion exchange membrane 23, a cathode plate 21, a cation exchange membrane 24, an anode plate 26, a first insulating mesh 22, a second insulating mesh 25, and a gas treatment box 3.

[0055] The outer casing 1 is H-shaped and includes a cathode chamber 8a, an anode chamber 9a, and an electrolysis chamber 6a arranged laterally between the cathode chamber 8a and the anode chamber 9a. The cathode chamber 8a and the anode chamber 9a are both arranged longitudinally. The cathode chamber 8a is used to generate strongly alkaline water and has a first water inlet port 1a and a first water outlet port 2a. The anode chamber 9a has a second water inlet port 4a and a second water outlet port 5a. Specifically, the outer casing 1 includes a first shell 11, an intermediate shell 13, and a second shell 12. The first shell 11 includes a first vertical portion 111 and a first horizontal portion 112 extending laterally from the middle of the first vertical portion 111. The inner cavity of the first vertical portion 111 forms the cathode chamber 8a. The second shell 12 includes a second vertical portion 121 and a second horizontal portion 122 extending laterally from the middle of the second vertical portion 121. The inner cavity of the second vertical portion 121 forms the anode chamber 9a. The intermediate shell 13 is sealed and assembled between the first horizontal portion 112 and the second horizontal portion 122.

[0056] The height of the first outlet port 2a is level with the highest points of the anion exchange membrane 23 and the cation exchange membrane 24. A first electronic water level gauge 1e is provided along the height direction in the cathode chamber 8a. A second electronic water level gauge 2e is provided along the height direction in the anode chamber 9a. The electrolysis chamber 6a has a circulating brine inlet 131 that leads into the salt chamber 7a and a circulating brine outlet 132 that flows out of the salt chamber 7a.

[0057] An anion exchange membrane 23 is disposed in the electrolysis chamber 6a and near the cathode chamber 8a. Specifically, the anion exchange membrane 23 is located between the first horizontal section 112 and the intermediate shell 13. The anion exchange membrane 23 selectively allows cations from the salt chamber to pass through. The cathode plate 21 is disposed in the electrolysis chamber 6a and near the anion exchange membrane 23, away from the anode chamber 9a. During electrolysis, the cathode plate 21 undergoes an electron-gaining reaction, mainly producing OH- (alkaline electrolyzed water) and H2.

[0058] A cation exchange membrane 24 is disposed in the electrolysis chamber 6a, near the anode chamber 9a. Specifically, the cation exchange membrane 24 is located between the second horizontal section 122 and the intermediate shell 13. The cation exchange membrane 24 selectively allows anions from the salt chamber to pass through. A space exists between the cation exchange membrane 24 and the anion exchange membrane 23, forming the salt chamber 7a. The anode plate 26 is disposed in the electrolysis chamber 6a, near the cation exchange membrane 24 and away from the cathode chamber 8a. During electrolysis, the anode plate 26 undergoes an electron-loss reaction, primarily producing H₂. + (Acidic electrolyzed water) and O 2、 Cl2.

[0059] In this embodiment, the anion exchange membrane 23 is sandwiched on the annular sealing gasket 231 at its periphery, and the cation exchange membrane 24 is sandwiched on the annular sealing gasket 241 at its periphery.

[0060] A first insulating mesh 22 is disposed between the anode plate 26 and the cation exchange membrane 24. A second insulating mesh 25 is disposed between the cathode plate 21 and the anion exchange membrane 23. The insulating meshes serve to protect the ion exchange membrane, accelerate venting, inhibit scale deposition, and accelerate ion transfer.

[0061] The anode chamber 9a has an outlet port 3a, and the electrolysis chamber 6a has an inlet port 113 on the side near the cathode chamber 8a. The inlet end of the gas treatment box 3 is connected to the outlet port 3a, and the outlet end is connected to the inlet port 113. The gas treatment box 3 has an exhaust pipe 31 and an overflow port 34, and the exhaust pipe 31 is equipped with a gas valve 32. The chlorine gas generated in the anode chamber is introduced into the gas treatment chamber, reacts with alkaline electrolyzed water, and the waste liquid is discharged into the sewer, which can effectively prevent chlorine gas from being released into the air.

[0062] In this embodiment, the water pump, solenoid valve, and electronic water level gauge can all be automatically controlled via the control panel to achieve automatic liquid addition and replenishment, and can output acidic electrolyzed water with the required pH value as required.

[0063] In this embodiment, the electrolysis power supply adopts a constant current power supply (conventional electrolysis method) with a maximum current limit. When the maximum current is exceeded, the power supply will automatically adjust the voltage to ensure that the electrolysis current does not exceed the maximum set value. Thus, even if an excessive amount of electrolyte salt is added to the salt chamber, the anions and cations can be controlled to enter the anode and cathode chambers at a constant concentration through the anion and cation exchange membranes to participate in electrolysis. The electrolyte will not be consumed excessively, thereby reducing the frequency of electrolyte salt addition and ensuring electrolysis stability.

[0064] The double-diaphragm electrolyzer integrates a large-capacity anode chamber (for generating strongly acidic electrolyzed water) and a large-capacity cathode chamber (for generating strongly alkaline electrolyzed water). Through static electrolysis, a large amount of low-pH strongly acidic electrolyzed water (pH≤3) is generated in the anode chamber, while a large amount of high-pH strongly alkaline electrolyzed water (pH≥11) is generated in the cathode chamber. The salt chamber, composed of anion and cation exchange membranes, is circulated with a chloride solution (preferably sodium chloride). The anions and cations in the salt solution selectively pass through the anion and cation exchange membranes into the anion and anode chambers, respectively, and excess salt solution does not enter the anion and anode chambers. This ensures smooth electrolysis while avoiding contamination of the electrolyzed water by excess electrolytes.

[0065] The H-structure design raises the middle electrolytic cell section to form a precipitation protection area at the bottom of the cathode and anode chambers, preventing scale and other solid impurities in the water from adhering to the ion exchange membranes and electrode plates, thus affecting performance and lifespan.

[0066] The H-type static water electrolysis module features a structure where the outlets of the cathode and anode chambers are level with the top of the diaphragm. Combined with an electronic water level gauge for real-time liquid level monitoring, this design maintains the minimum liquid level above the diaphragm and ensures that the cathode and anode chambers always have a bottom liquid to wet the diaphragm, preventing the diaphragm from drying out and failing.

[0067] Acidic electrolyzed water real-time mixing combined with automatic replenishment water preparation system: 1) Mix pre-prepared ultra-low pH strongly acidic electrolyzed water reserve with another source of tap water, and automatically adjust the amounts of both (by controlling the water output through the water output time) to quickly prepare acidic electrolyzed water solutions with different pH values ​​and dosages to meet different scenarios and cleaning sequences; 2) Further, through the design and control of the automatic replenishment system for acidic electrolyzed water, the automatic replenishment and preparation of ultra-low pH strongly acidic electrolyzed water reserve (electrolysis time control) is achieved, without user operation; 3) In addition, by mixing pre-prepared ultra-low pH strongly acidic electrolyzed water reserve with another source of tap water to prepare acidic electrolyzed water with different pH values ​​and dosages, instead of direct electrolysis, the amount of soft water required for electrolysis is greatly reduced, thereby reducing the volume of soft water resin and extending its lifespan.

[0068] A reliable and low-cost method for pH value confirmation: This method uses theoretical formulas to precisely configure acidic electrolyzed water with different pH values, accurately replenishes the target pH electrolyzed water, and prepares it at regular intervals. Compared with traditional pH sensor methods, this method is more reliable and lower in cost.

[0069] Chlorine treatment chamber: The factory-installed alkaline electrolyzed water generated in the cathode chamber. During the electrolysis process, the chlorine gas generated in the anode chamber (acidic electrolyzed water generation chamber) is introduced into the gas treatment chamber. After reacting with the alkaline electrolyzed water, the waste liquid is discharged into the sewer, effectively preventing chlorine gas from being released into the air. Waste liquid will be discharged and alkaline electrolyzed water will be replenished periodically.
