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 electrolytic water. This invention also relates to an electrolytic water platform capable of providing electrolytic water. Background Technology

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode. Most electrolytic cells use ion-exchange membranes (also called diaphragms) to separate the anode and cathode chambers. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the anode-solution interface, and a reduction reaction occurs at the cathode-solution interface, thus producing electrolyzed water.

[0003] Electrolysis produces highly alkaline electrolyzed water, which is safe, highly effective at cleaning, has a wide cleaning range (suitable for various types of dirt), and also has antibacterial properties, making it a representative of green cleaning agents on the market. Highly alkaline electrolyzed water can replace most cleaning agents on the market, but conventional methods for preparing highly alkaline electrolyzed water have the following problems:

[0004] First, the pH value is low and the output water volume is limited: Conventional electrolyzers use flow electrolysis, which means that by electrolyzing the flowing water / electrolyte solution, the required strongly alkaline electrolyzed water is discharged immediately at the outlet of the cathode chamber. However, this method has a short electrolysis time, a low pH value of the output water, and a limited output water volume.

[0005] Secondly, adding electrolytes is troublesome and produces wastewater: the preparation of strongly alkaline electrolyzed water requires the addition of electrolytes. Conventional flow-through electrolyzers use a method of continuously introducing electrolytes into the anode chamber, which not only produces wastewater but also requires a continuous supply of electrolytes, making it unsuitable for household use.

[0006] Third, it can only produce one pH value: different cleaning scenarios and different cleaning sequences require different pH values ​​of alkaline electrolyzed water. Conventional electrolyzers can only produce strongly alkaline 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 unsuitable for multi-scenario use in the home.

[0007] Fourth, core components are easily clogged by scale and solid impurities, affecting performance: During electrolysis, OH- ions are generated in the cathode chamber. These OH- ions combine with calcium and magnesium ions in tap water to form scale, which easily adheres to the diaphragm and electrode plates of the electrolytic cell, affecting electrolysis efficiency or even causing failure. Therefore, soft water electrolysis is required. Conventional methods produce the required electrolyzed water through direct electrolysis, requiring a large volume of soft water, resulting in a larger soft water module and a limited lifespan. Furthermore, impurities and electrolytes in the water can precipitate solids due to temperature variations. If these solids adhere to the diaphragm and electrode plates, they will also affect the performance of both.

[0008] Fifth, the core component, the diaphragm, needs to be protected by immersion: the preparation of 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. Summary of the Invention

The aforementioned cathode chamber and anode chamber are both arranged longitudinally. The aforementioned cathode chamber is used to generate strongly alkaline water and has an inlet port and an outlet port. The aforementioned anode chamber is used to hold electrolytes.

[0014] A cation exchange membrane is disposed in the aforementioned electrolysis chamber, which divides the electrolysis chamber into two parts;

[0015] The anode plate is disposed within the aforementioned electrolysis chamber, close to the aforementioned cation exchange membrane, and away from the cathode chamber; and

[0016] The cathode plate is located in the aforementioned electrolysis chamber and is close to the aforementioned cation exchange membrane and away from the anode chamber.

[0017] Preferably, the cathode chamber is equipped with a liquid level sensor, the height of which is level with the highest point of the electrolysis chamber.

[0018] Preferably, the height of the outlet port of the cathode chamber is level with the highest point of the cation exchange membrane.

[0019] 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 cation exchange membrane. The insulating mesh has the functions of protecting the cation exchange membrane, accelerating venting, inhibiting scale deposition, and accelerating ion transfer.

[0020] Preferably, the outer shell includes a first shell and a second shell integrally formed with the first 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 second horizontal portion and the first horizontal portion are sealed together to form the electrolysis chamber. The cation exchange membrane is disposed between the second horizontal portion and the first horizontal portion.

[0021] The technical solution adopted by this invention to solve the second and third technical problems mentioned above is: a strongly alkaline water electrolysis base station, characterized in that it includes...

[0022] The water electrolysis module has an inlet port and an outlet port;

[0023] The water inlet pipe is connected to the aforementioned water inlet port;

[0024] The water softening module is installed on the aforementioned water inlet pipe;

[0025] The water outlet pipe is connected to the aforementioned water outlet port;

[0026] Branch pipes connect the aforementioned inlet and outlet pipes;

[0027] Solenoid valves are used to regulate the flow rate of the aforementioned inlet and branch water pipes; and

[0028] The control board is connected to the aforementioned liquid level sensor and solenoid valve control.

[0029] The solenoid valve has at least an inlet end, a first outlet end, and a second outlet end. The inlet end is connected to tap water, the first outlet end is connected to the inlet port of the water electrolysis module, and the second outlet end is connected to a branch pipeline.

[0030] The solenoid valve includes a first solenoid valve installed on the inlet pipe and a second solenoid valve installed on the branch pipe.

[0031] The inlet pipe, outlet pipe, and branch pipe are each equipped with a first water pump, a second water pump, and a third water pump, respectively.

[0032] Compared with the prior art, the advantages of the present invention are as follows:

[0033] The outer casing integrates the electrolytic cell, a large-capacity cathode chamber (for generating strongly alkaline electrolyzed water), and a large-capacity anode chamber (salt chamber) into a single, more compact design. In the cathode chamber, static electrolysis produces a large quantity of ultra-high pH strongly alkaline electrolyzed water (pH ≥ 11, preferably pH 12.5). In the anode chamber, a large quantity of high-concentration electrolyte salts can be added, and combined with static electrolysis, this ensures long-term use without frequent electrolyte salt additions, and produces no wastewater during electrolysis. The anode chamber stores a large quantity of electrolyte salts required for electrolysis, and is pre-filled with a high-concentration brine at the factory, sufficient for extended electrolysis use without frequent replacements, and produces no wastewater during electrolysis.

[0034] By mixing a pre-prepared ultra-high pH strongly alkaline electrolyzed water reserve with another source of tap water, and automatically adjusting the amounts of both (by controlling the water output time), alkaline electrolyzed water solutions with different pH values ​​and dosages can be quickly prepared to meet different scenarios and cleaning sequences. In addition, by mixing the pre-prepared ultra-high pH strongly alkaline electrolyzed water reserve with another source of tap water to prepare alkaline electrolyzed water with different pH values ​​and dosages, rather than by 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.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] Example 1, as Figure 1 and Figure 4As shown, the strongly alkaline electrolyzed water base station in this embodiment can serve as a platform to provide cleaning agents and can be applied to various cleaning occasions, such as dishwashers, floor scrubbers, or wall cleaning. Specifically, it includes an electrolyzed water module 10, an inlet pipe 41, a soft water module 2a, an outlet pipe 42, a branch pipe 43, and a solenoid valve 1a. The electrolyzed water module 10 has an inlet port 111 and an outlet port 112. The inlet pipe 41 is connected to the inlet port 111. The soft water module 2a is located on the inlet pipe 41 and provides the soft water required for electrolysis, preventing scale from depositing on the electrode plates and cation exchange membrane, which would affect the effect and lifespan.

[0043] The outlet pipe 42 is connected to the outlet port 112; the branch pipe 43 is connected between the inlet pipe 41 and the outlet pipe 42; the solenoid valve 1a is used to regulate the flow rate of the inlet pipe 41 and the branch pipe 43; the control board 100 is connected to the liquid level sensor 113 and the solenoid valve 1a.

[0044] In this embodiment, the solenoid valve 1a is a three-way valve with an inlet end, a first outlet end, and a second outlet end. The inlet end is connected to tap water, the first outlet end is connected to the inlet port 111 of the water electrolysis module 10, and the second outlet end is connected to the branch pipe 43. A first water pump 31, a second water pump 32, and a third water pump 33 are respectively installed on the inlet pipe 41, the outlet pipe 42, and the branch pipe 43. The first water pump 31, the second water pump 32, and the third water pump 33 are all connected to the control board 100 for control.

[0045] like Figure 2 and Figure 3 As shown, the water electrolysis module in this embodiment includes a shell, a cation exchange membrane 5, an anode plate 62, and a cathode plate 61.

[0046] The outer casing is H-shaped, including a cathode chamber 1b, an anode chamber 2b, and an electrolysis chamber 3b horizontally positioned between the cathode chamber 1b and the anode chamber 2b. Both the cathode chamber 1b and the anode chamber 2b are arranged vertically. The cathode chamber 1b is used to generate strongly alkaline water and has an inlet port 111 and an outlet port 112. The anode chamber 2b is used to hold the electrolyte. A level sensor 113 is installed in the cathode chamber 1b, with its height leveled with the highest point of the electrolysis chamber 3b, to monitor the lowest liquid level within the cathode chamber. The outlet port 112 of the cathode chamber 1b is leveled with the highest point of the cation exchange membrane 5. Combined with the level sensor, this ensures that the cathode chamber always has a protective bottom solution for wetting the cation exchange membrane 5, preventing the cation exchange membrane 5 from drying out and failing.

[0047] Specifically, the outer shell includes a first shell 1 and a second shell 2 that is mated and fitted together to form an integral part. The first shell 1 includes a first vertical portion 11 and a first horizontal portion 12 that extends laterally from the middle of the first vertical portion 11. The inner cavity of the first vertical portion 11 forms a cathode chamber 1b. The second shell 2 includes a second vertical portion 21 and a second horizontal portion 22 that extends laterally from the middle of the second vertical portion 21. The inner cavity of the second vertical portion 21 forms an anode chamber 2b. The second horizontal portion 22 and the first horizontal portion 12 are sealed together to form an electrolysis chamber 3b. A cation exchange membrane 5 is disposed between the second horizontal portion 22 and the first horizontal portion 12.

[0048] A cation exchange membrane 5 is disposed in the electrolysis chamber 3b, dividing the electrolysis chamber 3b into two parts; the periphery of the cation exchange membrane 5 is sandwiched between annular sealing gaskets 81 and 82. Cations in the anode chamber can continuously enter the cathode chamber through the ion exchange membrane, providing the conductivity required for electrolysis. At the same time, the cation exchange membrane separates the liquid and gas in the anode and cathode chambers, thereby producing strongly alkaline electrolyzed water. The cation exchange membrane 5 will become ineffective when dry and needs to be moistened for storage and use.

[0049] The anode plate 62 is located inside the electrolysis chamber 3b, close to the cation exchange membrane 5 and away from the cathode chamber 1b; the cathode plate 61 is located inside the electrolysis chamber 3b, close to the cation exchange membrane 5 and away from the anode chamber 2b. A first insulating mesh 72 is provided between the anode plate 62 and the cation exchange membrane 5. A second insulating mesh 71 is provided between the cathode plate 61 and the cation exchange membrane 5. The first insulating mesh 72 and the second insulating mesh 71 have the functions of protecting the cation exchange membrane 5, accelerating venting, inhibiting scale deposition, and accelerating ion transfer.

[0050] In this embodiment, the outer casing integrates the electrolytic cell, a large-capacity cathode chamber (for generating strongly alkaline electrolyzed water), and a large-capacity anode chamber (salt chamber). In the cathode chamber, static electrolysis generates a large quantity of ultra-high pH strongly alkaline electrolyzed water (pH ≥ 11, preferably pH 12.5). In the anode chamber, a large quantity of high-concentration electrolyte salts can be added, and combined with static electrolysis, this ensures long-term use without frequent electrolyte salt additions, and no wastewater is generated during electrolysis. The anode chamber stores a large quantity of electrolyte salts (preferably carbonates) required for electrolysis, and is pre-filled with a high-concentration brine at the factory, sufficient for extended electrolysis use without frequent replacement, and also generates no wastewater during electrolysis.

[0051] 1) A pre-prepared ultra-high pH strongly alkaline electrolyzed water reserve solution is mixed with another source of tap water, and the amount of both is automatically controlled (by controlling the water output time) to quickly prepare alkaline electrolyzed water solutions with different pH values ​​and dosages to meet different scenarios and cleaning sequences; 2) Furthermore, through the design and control of an automatic electrolyzed water replenishment system, the automatic replenishment and preparation of ultra-high pH strongly alkaline electrolyzed water reserve solution is achieved (controlled by electrolysis time), without the need for user operation; 3) In addition, by mixing the pre-prepared ultra-high pH strongly alkaline electrolyzed water reserve solution with another source of tap water to prepare alkaline 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.

[0052] The method of precisely configuring alkaline electrolyzed water with different pH values ​​using theoretical formulas, accurately replenishing the target pH electrolyzed water, and preparing it at timed intervals is more reliable and less expensive than traditional pH sensor methods.

[0053] Example 2, as Figure 5 and Figure 6 As shown, the solenoid valves in this embodiment include a first solenoid valve 11a located on the inlet pipe 41 and a second solenoid valve 12a located on the branch pipe 43. Other structural details are shown in Embodiment 1. The control board 100 is electrically connected to the level sensor 113, the first solenoid valve 11a, and the second solenoid valve 12a. Other structural details are shown in Embodiment 1.
