Description

Electrolytic cell and cleaning machine using the same Technical Field

[0001] The present invention relates to the technical field of electrolytic equipment and kitchen equipment, and in particular to an electrolytic cell and a cleaning machine using the electrolytic cell. The electrolytic cell can also be used in electrolytic equipment not used in the kitchen. Background Art

[0002] An electrolytic cell consists of a cell body, an anode, and a cathode. Most electrolytic cells are separated by an ion exchange membrane (also called a diaphragm). Depending on the electrolyte, they are classified into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. 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, producing electrolyzed water.

[0003] For example, Chinese invention patent application CN108609693A (application number 201810264395.4) discloses a method for preparing acidic water and alkaline water, which is to electrolyze salt water to form cations and anions, which move toward the two poles of the electrolysis electrode respectively, and generate hydrogen ions and highly active chlorine gas from the anode. The chlorine gas dissolves in water to generate hypochlorous acid and hydrochloric acid solution as acidic water, and generates hydroxide ions and hydrogen from the cathode to form sodium hydroxide solution as alkaline water.

[0004] The following problems exist in the existing electrolyzed water preparation process:

[0005] First, the ion exchange membrane is a unique polymer membrane containing ionic groups that has the ability to selectively transmit cations or anions in the solution. It has a certain degree of flexibility. Over time, it will be affected by air pressure and water pressure, and will deform. It may even contact the electrode and cause dry burning, affecting the water output and the life of the electrolytic cell. This problem is particularly serious in small electrolytic cells.

[0006] Second, during the electrolysis process, a large number of bubbles are generated on the cathode and anode sheets. These bubbles accumulate on the electrode sheets, ion exchange membranes, and the water channels within the electrolytic cell, resulting in high voltage and energy consumption for the electrolysis system. This also reduces the effective electrolysis area, lowering the electrolysis reaction efficiency, leading to low effluent pH, and obstructing the flow of water, making the pH and voltage extremely unstable. Furthermore, the air pressure can exacerbate the deformation of the ion exchange membrane in the middle. This problem is particularly severe in small electrolytic cells.

[0007] Third, during the electrolysis process, the OH generated at the cathode (negative electrode) - Will react with Ca in water 2+ Mg 2+ The reaction generates scale, which is deposited on the cathode and ion exchange membrane, affecting the electrolysis effect and the life of the electrolytic cell;

[0008] Fourth, during the electrolysis process, ions need to first pass through the ion exchange membrane from the anode chamber into the cathode chamber before they can promote the entire electrolysis reaction. However, during the electrolysis reaction, ions and products tend to gather around the electrode sheet, which is not conducive to the diffusion and transfer of ions and the uniformity of products, thereby affecting the electrolysis efficiency and pH stability.

[0009] For example, Chinese invention patent application CN113474492A (application number CN202080012097.1) discloses an electrolyte manufacturing device and an electrolyte manufacturing method. In this manufacturing method, a partition mesh is set between the diaphragm and the electrode sheet to separate the diaphragm and the electrode sheet to prevent the diaphragm from contacting the electrode sheet and causing dry burning. Although local micro-turbulence can be formed in the process of water flow passing through the mesh, its turbulence effect is limited, and it cannot effectively accelerate exhaust, inhibit scale deposition, and accelerate ion transfer.

[0010] In addition, existing electrolytic cell-related technologies have been applied to solutions for kitchen dishwashers, such as a method for controlling electrolyzed water in a dishwasher disclosed in Chinese invention patent application CN117414087A (application number CN202311345395.4). This method uses an electrolysis module to electrolyze water to produce strong alkaline electrolyzed water (pH ≥ 11), which not only has a strong cleaning effect, but also has an antibacterial effect. It can replace dishwashing powder for washing dishes. The main component of alkaline electrolyzed water is water, and it does not contain surfactants, oxidants, enzymes and other chemical substances. It is simpler and safer than conventional dishwashing powder and other ingredients. By electrolyzing water to produce it, it can be used to wash dishes directly, solving the problems of users frequently adding detergents manually, poorly controlling the amount, easily leaving solid powder residues, and inconvenient purchase and storage.

[0011] However, in the above solution, the electrolytic water module is external and exists as a component independent of the dishwasher body, which occupies a large space.

[0024] In order to achieve multiple sealing, one side of the annular sealing gasket corresponds to at least two annular protrusions arranged at intervals, and of the two adjacent annular protrusions, the latter annular protrusion is located on the outer periphery of the former annular protrusion.

[0025] In order to facilitate the supply of raw materials and the discharge of electrolyzed water, the tank body portion corresponding to each electrode chamber is provided with a liquid inlet and a liquid outlet that are in communication with the electrode chamber.

[0077] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0078] In the present specification and claims, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Because the embodiments disclosed herein can be arranged in various orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0079] Figures 1 to 4 illustrate a preferred embodiment of an electrolytic cell according to the present invention. The electrolytic cell comprises a cell body 1, a diaphragm 2, an electrode sheet 3, and an insulating screen 4. The electrolytic cell in this embodiment is a single-diaphragm cell, but can also be designed as a dual-diaphragm cell or a diaphragm-free cell as needed.

[0080] The trough body 1 is formed by two covers 11 assembled front and back using fasteners. A closed inner cavity is formed between the two covers 11. Two annular gaskets 12 arranged side by side are used to seal the opposing end surfaces of the two covers 11. In this embodiment, at least two spaced annular protrusions 121 are provided on both sides of the annular gaskets 12. Of the two adjacent annular protrusions 121, the latter one is located outside the former, thus achieving multiple seals.

[0081] The diaphragm 2 is a cation exchange membrane, arranged vertically in the inner cavity of the above-mentioned tank body 1, and the periphery of the diaphragm 2 is sandwiched between the above-mentioned two annular sealing gaskets 12. The above-mentioned diaphragm 2 is in one piece and divides the inner cavity of the tank body 1 into two electrode chambers 110. The electrode chamber 110 located between the front cover body 11 and the diaphragm 2 is denoted as the cathode chamber 110a, and the electrode chamber 110 located between the rear cover body 11 and the diaphragm 2 is denoted as the anode chamber 110b. The lower and upper portions of each cover body 11 are respectively provided with a liquid inlet 111 and a liquid outlet 112 that penetrate the corresponding electrode chamber 110. Therefore, the water in each electrode chamber 110 flows from bottom to top.

[0082] The number of electrode sheets 3 is a pair, respectively designated as cathode sheet 3a and anode sheet 3b. The cathode sheet 3a is substantially vertically arranged in front of the cathode chamber 110a, and the anode sheet 3b is substantially vertically arranged in the rear of the anode chamber 110b. The top of each electrode sheet 3 has a conductive post 31, which passes upward through the corresponding cover 11 and is exposed on the top wall of the cover 11. The conductive posts 31 on the cathode sheet 3a and the anode sheet 3b are respectively used to electrically connect to the negative and positive poles of an external power supply. In addition, each electrode chamber 110 is provided with at least two mounting seats 13 arranged at intervals along the circumference of the electrode sheet 3. The mounting seat 13 is provided with a slot 131 for inserting the edge of the electrode sheet 3 to achieve stable positioning of the electrode sheet 3.

[0083] There are two insulating screens 4, one corresponding to each of the two electrode chambers 110, and each located within the corresponding electrode chamber 110, for separating the adjacent diaphragms 2 and electrode sheets 3. Specifically, the insulating screen 4 is flat, with a plurality of mesh holes 41 on its surface for fluid to pass through. The insulating screen 4 is freely suspended to allow it to move freely under the action of the water flow. In this embodiment, the insulating screen 4 is made of a material (food grade) that is resistant to high and low temperatures, strong acids and alkalis, and has good insulation properties, preferably food-grade Teflon. The porosity of the insulating screen 4 is greater than 1%, preferably 50%, and the thickness of the insulating screen 4 is greater than 0.1 mm, preferably 0.4 mm. The mesh holes 41 of the insulating screen 4 are preferably square holes, with a side length of preferably 1 mm, to maximize the micro-turbulence formed when the water flows through the mesh holes 41.

[0084] In addition, the surface of the electrode sheet 3 facing the insulating screen 4 has at least two insulating protrusions 331 spaced along its length to prevent the insulating screen 4 from drying out when placed against the electrode sheet 3. In this embodiment, the electrode sheet 3 has a mounting hole 32 through which a bolt 33 is threaded. The head of the bolt 33 is formed with the insulating protrusion 331, and the tail of the bolt 33 is threaded with a nut 34. This structural design allows for easy adjustment of the spacing between the insulating protrusion 331 and the diaphragm 2, thereby adjusting the free space for the insulating screen 4.

[0085] The working principle of this embodiment is as follows: during operation, the electrolyte enters the electrode chamber 110 through the liquid inlet 111, a reduction reaction occurs at the interface between the cathode plate 3a and the solution, and an oxidation reaction occurs at the interface between the anode plate 3b and the solution to produce electrolyzed water. During the electrolysis process, first, the insulating screen 4 is separated between the diaphragm 2 and the electrode plate 3, which can effectively prevent the diaphragm 2 from contacting the electrode plate 3 and causing dry burning. The insulating protrusion 331 on the electrode plate 3 can prevent the insulating screen 4 from being attached to the electrode plate 3 and causing dry burning; second, the mesh 411 of the insulating screen 4 forms a local micro-disturbance, and the movement of the insulating screen 4 forms a dynamic disturbance, which can accelerate exhaust, inhibit scale deposition, and accelerate ion transfer.

[0086] The electrolytic cell advantages of the present invention are as follows:

[0087] (1) By adding an insulating screen 4 between the diaphragm 2 and the electrode sheet 3, the diaphragm 2 is supported and protected by a partition. The dynamic disturbance formed by the movement of the insulating screen 4 and the local disturbance formed by the mesh of the insulating screen 4 are utilized to greatly accelerate the discharge of bubbles in the electrode sheet 3, the diaphragm 2 and the water path of the electrolytic cell. Compared with the currently commonly used method of designing an exhaust port on the electrolytic cell, which requires additional sealing design and other auxiliary exhaust design methods, this accelerated exhaust method has better exhaust effect, simpler structure, and controllable cost, and is very suitable for small electrolytic cells.

[0088] (2) The dynamic disturbance formed by the movement of the insulating screen 4 and the local disturbance formed by the mesh of the insulating screen 4 are used to prevent scale deposition. Compared with the currently commonly used positive and negative electrode switching descaling method, there is no need for a catalytic coating on both the positive and negative electrodes that can participate in the positive electrode reaction and frequent positive and negative electrode switching. It has a low cost, a simple structure, low requirements for electronic control, and a guaranteed electrode life.

[0089] (3) Using the dynamic disturbance formed by the movement of the insulating screen 4 and the local disturbance formed by the mesh of the insulating screen 4, the ion diffusion and transfer are accelerated, and the pH value and stability of the effluent are improved;

[0090] (4) The insulating protrusion 331 designed on the electrode sheet 3 can effectively prevent the insulating screen 4 from being dry-burned when it is attached to the electrode sheet 3. In addition, the insulating protrusion 331 is formed by a pair of bolts and nuts. In this way, the distance between the insulating protrusion 331 and the diaphragm 2 is adjustable. During the actual test, the activity space of the insulating screen 4 can be adjusted by fine-tuning the distance, thereby achieving the best exhaust effect of the insulating screen 4.
