Description

Technical Field

[0001] This utility model relates to the field of electrochemical water treatment technology for household appliances, and in particular to a compact electrochemical ozone water catalytic electrode module and electrolysis device for household appliances. Background Technology

[0002] With the increasing demand for water treatment in residential settings, traditional silver ion and ultraviolet sterilization technologies have drawbacks such as residual risks or limited effective range. Ozone, with its high oxidation potential of 2.07V (in water), can effectively kill bacteria, decompose harmful substances such as formaldehyde and dyes, and leave no residue, making it an ideal choice.

[0003] However, current mainstream ozone water catalytic electrode assemblies adopt a sandwich-type flat plate structure (see...). Figure 1 The anode plate electrode is sandwiched between two cathode plate plates. This design makes it difficult for ozone bubbles generated on the anode surface during electrolysis to escape, forming a bubble-covered layer. Bubble retention causes a double negative effect: first, the reduced effective reaction area leads to a decrease in electrolysis efficiency; second, the anode metal substrate experiences localized overheating due to the bubble blockage, accelerating the anode corrosion rate and significantly shortening the equipment's service life.

[0004] Meanwhile, due to the compact internal space of home appliances, the electrode assembly needs to be small in size, making it difficult to adapt to traditional multi-layer stacked structures. In addition, the bolts of traditional electrode assemblies can only be installed vertically in the electrolytic cell, which cannot meet the installation requirements of different scenarios. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a compact electrochemical ozone water catalytic electrode module for household appliances. This module solves the problem that in existing "sandwich" plate electrode assemblies, the ozone bubbles generated by the anode plate electrode during electrolysis are difficult to escape, leading to a reduction in effective reaction area, decreased electrolysis efficiency, accelerated anode corrosion rate, and shortened equipment lifespan.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compact electrochemical ozone water catalytic electrode module for household appliances includes an anode assembly and a cathode assembly; the anode assembly includes a titanium-based support plate, and anode electrode plates are vertically fixed on one or both sides of the titanium-based support plate.

[0008] The cathode assembly includes a metal support plate symmetrical to the titanium-based support plate, and cathode electrode sheets are vertically fixed on one or both sides of the metal support plate.

[0009] The titanium-based support plate and the metal support plate are provided with mounting parts, which are used to pass through bolts so that after the anode electrode sheet and the cathode electrode sheet are nested in an alternating manner, they are electrically connected to the titanium-based support plate and the metal support plate by bolts, thereby realizing the catalytic electrolysis function of water by the anode assembly and the cathode assembly.

[0010] In some embodiments, the mounting portion is a bolt hole, which is respectively provided on the titanium-based support plate and the metal support plate, and the bolt hole is used to pass a bolt through.

[0011] In some embodiments, the mounting part is a mounting plate with bolt holes, which is respectively disposed on a titanium-based support plate and a metal support plate, and the bolt holes on the mounting plate are used for threading bolts.

[0012] In some embodiments, the titanium-based support plate is made of TA1 or TA2 material; the metal support plate is made of any one of titanium steel, stainless steel or carbon steel.

[0013] In some embodiments, a plurality of anode electrode sheets are arranged at uniform intervals of 2-5 mm on a titanium-based support plate; similarly, a plurality of cathode electrode sheets are arranged at uniform intervals of 2-5 mm on a metal support plate.

[0014] An electrolysis device using the aforementioned compact electrochemical ozone water catalytic electrode module for household appliances includes a cover, a base, and a circuit board. The circuit board is disposed on the back of the base, and an insulating hole is provided on the front of the base. The cover is detachably connected to the base. The anode assembly and the cathode assembly are disposed inside the base. Bolts pass through the insulating hole and are electrically connected to the circuit board so that after the anode electrode plates and cathode electrode plates are interlocked and nested, they are electrically connected to the titanium-based support plate and the metal support plate by the bolts.

[0015] In some embodiments, the electrolysis apparatus further includes a mounting row disposed within a base for mounting and fixing the anode electrode plate and the cathode electrode plate.

[0016] Compared with the prior art, the beneficial effect of this utility model is that the anode electrode and cathode electrode are nested in an alternating manner to form an alternating electrolytic array. The channels formed by this alternating electrode have the following technical breakthroughs compared with the existing flat plate electrolytic structure:

[0017] 1. The anode and cathode electrodes form a vertically interlaced "honeycomb" electrolytic array, creating multi-scale turbulent channels. This structure reduces the average residence time of ozone bubbles from 2-3 seconds in traditional structures to less than 1 second, increasing bubble escape efficiency by more than 2 times and effectively preventing ineffective accumulation of ozone gas on the electrode surface.

[0018] 2. The staggered electrode plates create a "liquid film shear effect," generating micro-eddies in the flowing water during electrolysis, thus increasing the renewal frequency of the contact interface between ozone gas and the electrolyte by 40%. Experimental data show that the ozone dissolution concentration gradient increased from 0.25 mg / L·cm in the traditional structure to 0.38 mg / L·cm.

[0019] 3. The nested electrode array creates a uniform electric field distribution, reducing the standard deviation of the current density on the anode surface to 0.003 A / cm². 2 (The traditional structure is 0.01A / cm) 2 This process ensures that the ozone generation reaction occurs uniformly on the electrode surface. Infrared thermal imaging shows that the area of ​​the highest temperature region decreased from 65% to 38%, extending the electrode's lifespan by more than 30%. Attached Figure Description

[0031] In the description of the embodiments of this utility model, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example 1, see Figure 2 , Figure 3 This utility model provides a compact electrochemical ozone water catalytic electrode module for household appliances, which is a circular electrode assembly, including an anode assembly 1 and a cathode assembly 2.

[0033] Anode assembly 1 includes a titanium-based support plate 101, on one or both sides of which anode electrode plates 102 are vertically fixed.

[0034] The cathode assembly 2 includes a metal support plate 201 symmetrically arranged with the titanium-based support plate 101, and the cathode electrode sheet 202 is vertically fixed on one or both sides of the metal support plate 201.

[0035] The titanium-based support plate 101 and the metal support plate 201 are provided with mounting parts. The mounting parts are used to pass through bolts 3 so that after the anode electrode plate 102 and the cathode electrode plate 202 are nested in an alternating manner, they are electrically connected to the titanium-based support plate 101 and the metal support plate 201 by bolts (3), thereby realizing the catalytic electrolysis function of the anode assembly 1 and the cathode assembly 2 on water, so as to generate ozone in the water for disinfection and degradation of pollutants.

[0036] Furthermore, participate Figure 3 The mounting part is a bolt hole 5, which is respectively set on the titanium-based support plate 101 and the metal support plate 201. The bolt hole 5 is used to pass through the bolt 3.

[0037] Furthermore, the titanium-based support plate 101 is made of TA1 or TA2 material; the metal support plate 201 is made of any one of titanium steel, stainless steel or carbon steel.

[0038] Furthermore, multiple anode electrode sheets 102 are provided, and these multiple anode electrode sheets 102 are evenly spaced on the titanium-based support plate 101 at a spacing of 2-5 mm; similarly, multiple cathode electrode sheets 202 are provided, and these multiple cathode electrode sheets 202 are evenly spaced on the metal support plate 201 at a spacing of 2-5 mm.

[0039] See Figures 4-7 The present invention also provides an electrolysis device that uses the above-mentioned compact electrochemical ozone water catalytic electrode module for household appliances. The electrolysis device includes a cover 41, a base 42 and a circuit board 43. The base 42 has an insulating hole 422 on its front side, and the insulating hole 422 penetrates the base 42 for bolt 3 to be inserted, so as to ensure the electrical connection between the electrode assembly and the circuit board while maintaining insulation safety.

[0040] The base 42 has a mounting plate 421 on its front side for mounting the anode assembly 1 and the cathode assembly 2. The base 42 has a circuit board 43 on its back side.

[0041] During installation, bolt 3 passes sequentially through the bolt holes 5 of the anode assembly 1 and the cathode assembly 2, then through the insulation hole 422 of the base 42, and finally forms a stable connection with the circuit board 43. This design not only ensures the stable installation of the electrode assembly but also achieves electrical connection. Specifically, the electrical connection between the bolt and the circuit board can be achieved in two ways: one is to weld the bolt to the bottom of the circuit board; the other is to screw the bolt into the circuit board and then use a nut to secure it, thereby making the nut conductive to the circuit board.

[0042] The cover 41 is connected to the base 42 by a snap-fit ​​or other detachable connection method to form a complete electrolysis device housing, protecting the internal components from external environmental interference.

[0043] A rubber insulating ring may be provided inside the insulating hole 422. This design further enhances the waterproof performance and effectively prevents water from flowing along the bolt to the back of the base 42, thereby greatly reducing the risk of water coming into direct contact with the circuit board 43.

[0044] Example 2: To adapt to different installation environments or bases 42, the circular electrode assembly of Example 1 can also be modified into... Figure 8The square electrode assembly shown includes an anode assembly 7 and a cathode assembly 8. The anode assembly 7 includes a titanium-based support plate 701. Anode electrode pieces 702 are vertically fixed on one or both sides of the titanium-based support plate 701. There are multiple anode electrode pieces 702, which are evenly spaced on the titanium-based support plate 701.

[0045] The cathode assembly 8 includes a metal support plate 801 symmetrically arranged with the titanium-based support plate 701. Cathode electrode plates 802 are vertically fixed on one or both sides of the metal support plate 801. There are multiple cathode electrode plates 802, which are evenly spaced on the metal support plate 801.

[0046] The titanium-based support plate 701 and the metal support plate 801 are provided with mounting parts, which are mounting plates 6 with bolt holes. The mounting plates 6 with bolt holes are integrally connected to the titanium-based support plate 701 and the metal support plate 801. The bolt holes on the mounting plates 6 with bolt holes are used to pass bolts through, so that after the anode electrode plate 702 and the cathode electrode plate 802 are nested in an alternating manner, the titanium-based support plate 701 and the metal support plate 801 are electrically connected by bolts 3, thereby realizing the catalytic electrolysis function of the anode assembly 7 and the cathode assembly 8 on water, so as to generate ozone in the water for disinfection and degradation of pollutants.

[0047] The working principle of this utility model is as follows:

[0048] This utility model discloses a compact electrochemical ozone water catalytic electrode module for household appliances, mainly comprising an anode assembly 1 and a cathode assembly 2. These two components work together to achieve catalytic electrolysis of water to generate ozone for disinfection and degradation of pollutants. Specifically, bolts 3 are used to connect and fix the titanium-based support plate 101, and bolts 3 are also used to connect and fix the metal support plate 201, thereby ensuring electrical connectivity between the anode assembly 1 and the cathode assembly 2, providing the necessary conditions for the subsequent electrolysis process.

[0049] In practical applications, the compact electrochemical ozone water catalytic electrode module for household appliances of this invention is typically installed in an electrolysis device, which also includes a cover 41, a base 42, and a circuit board 43. The base 42 is made of plastic, and the circuit board 43 is located on the back of the base 42 to provide the direct current required for electrolysis. The anode assembly 1 and cathode assembly 2 are housed in mounting brackets 421 within the base 42. When the base 42 is submerged in water, the direct current from the circuit board 43 is conducted to the anode assembly 1 and cathode assembly 2 via bolts 3, creating an electric field between the anode electrode plate 102 and the cathode electrode plate 202.

[0050] Under the influence of an electric field, water molecules undergo an oxidation reaction on the surface of the anode electrode 102, producing ozone, oxygen, and hydrogen ions; simultaneously, a reduction reaction occurs on the surface of the cathode electrode 202, where hydrogen ions gain electrons to generate hydrogen gas. The reaction equations are as follows:

[0051] Half-reaction formula:

[0052] Anode (oxidation reaction): 3H₂O → O₃ + 6H + +6e -

[0053] Oxygen may also be generated: 2H₂O → O₂ + 4H₂O + +4e -

[0054] Cathode (reduction reaction): 6H + +6e - →3H2↑

[0055] Overall reaction (assuming only O3 is produced): 3H2O → O3 + 3H2↑

[0056] In this way, the catalytic electrolysis of water is achieved through the synergistic effect of anode component 1 and cathode component 2, and ozone with disinfection effect is generated in the water.

[0057] Ultimately, the compact electrochemical ozone water catalytic electrode module for household appliances of this invention can be applied to various household appliances, such as washing machines, water purifiers, disinfection cabinets, and air conditioners, providing users with a convenient and efficient ozone disinfection solution.

[0058] It should be noted that the compact electrochemical ozone water catalytic electrode module for household appliances involved in this utility model has a high degree of flexibility and diversity in its structural design. Specifically, its anode and cathode components are not limited to a specific shape, but can be modified in various ways according to actual application scenarios and needs. For example, they can be the circular structure shown in Example 1, the square structure presented in Example 2, or even any other arbitrary shape, as long as these shapes can meet the requirements of the electrolysis function and adapt to different installation environments or base designs.

[0059] Furthermore, the titanium-based support plates and metal support plates in the anode and cathode assemblies also have various possible variations. More importantly, the positions of the anode and cathode electrode plates on the support plates are not fixed. They can be placed not only at the edges of the support plates, but also in the middle of the support plates according to actual needs, or in other more complex layouts.

[0060] The core inventive concept of this utility model lies in the staggered nesting design of the anode and cathode electrode plates. This design forms an staggered electrolysis array, thereby significantly improving electrolysis efficiency and optimizing ozone generation. Therefore, as long as the electrode assembly design conforms to this core concept—that is, the anode and cathode electrode plates are arranged in a staggered nesting manner—regardless of variations in their specific shape, support plate structure, or electrode plate placement, it falls within the protection scope of this utility model. This flexible and diverse design approach allows the ozone water catalytic electrode assembly of this utility model to be widely applied in various scenarios, meeting the needs of different users.
