Description

Technical Field

[0001] This utility model relates to the field of heating technology, and in particular to an electrolysis device and a gas-fired hot water equipment. Background Technology

[0002] It is now common practice in hot water equipment to produce gas through electrolysis of electrode plates to supply sparkling water.

[0003] In related technologies, electrode plates are typically fixed within a water channel cavity. Electrolysis generates oxygen and hydrogen, which mix with the water flow and are discharged to form bubble water. To improve electrolysis efficiency, the electrode plates are sometimes machined into a toothed shape with multiple cantilever arms. This increases the reaction area and facilitates water flow while reducing obstruction. However, when these electrode plates with multiple cantilever arms are directly fixed to the cavity with bolts, the contact area is often small, leading to unstable fixation. Consequently, under the impact of water flow and the continuous vibration of bubbles generated by electrolysis, the cantilever arms of the electrode plates are prone to vibration. This vibration is often transmitted to the bolts, accelerating loosening and weakening the fastening force. This can not only cause abnormal noises but may also lead to contact between different electrode plates, creating a short circuit risk. Utility Model Content

[0004] The first technical problem solved by this invention is to provide an electrolysis device that can increase the stability and strength of the electrode plates, and prevent them from loosening and causing abnormal noise and short circuits.

[0005] The second technical problem solved by this utility model is to provide a gas-fired water heater that can increase the stability and strength of the electrode plates, preventing them from loosening and causing abnormal noise and short circuits.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] An electrolysis apparatus comprising:

[0008] A housing having a receiving cavity, and the housing also having an inlet and an outlet communicating with the receiving cavity;

[0009] A fixed seat assembly is disposed within the receiving cavity. The fixed seat assembly includes a first seat body and a plurality of second seat bodies, wherein the first seat body and the second seat bodies are located on opposite sides of the inner wall of the receiving cavity.

[0010] An electrode assembly includes an electrode plate, the electrode plate includes a fixing part and a plurality of cantilever arms, the plurality of cantilever arms are arranged at intervals and connected to the fixing part, the fixing part is fixed to a first base, and at least a portion of the cantilever arms are respectively fixed to a second base at one end away from the fixing part.

[0011] The electrolysis device described in this utility model has the following advantages compared with the prior art:

[0012] The fixing assembly includes a first base and multiple second bases, which are spaced apart from the first base, so that the fixing part can be fixed to the first base. At least one end of the cantilever away from the first base is fixed to the second base, and the cantilever is effectively supported and fixed. Thus, when the water flow impacts the cantilever, one end of the cantilever is firmly fixed by the fixing part fixed to the first base, and the other end is firmly fixed by the second base. This avoids vibration concentrated at a single point connection of the fixing part, thereby reducing the continuous vibration of the electrode plate caused by the water flow impact and the action of bubbles generated by electrolysis. On the one hand, it reduces the possibility of the electrode assembly loosening, and on the other hand, it reduces the possibility of different electrode plates coming into contact with each other due to vibration, thereby reducing the risk of abnormal noise and short circuit caused by loosening.

[0013] In one embodiment, the second base is provided with a groove, and at least a portion of the cantilever is respectively embedded in the corresponding groove at one end away from the fixing part.

[0014] In one embodiment, the electrode plate includes a positive electrode plate and a negative electrode plate, with the cantilever of the positive electrode plate and the cantilever of the negative electrode plate being alternately arranged; the fixing base group is provided in two groups, with the two first base bodies of the two fixing base groups being spaced apart and facing each other, and in the two fixing base groups, a plurality of second base bodies of one fixing base group are spaced around the first base body of the other fixing base group.

[0015] In one embodiment, the distance between the cantilever of the positive electrode plate and the cantilever of the negative electrode plate is L, where 0.5mm ≤ L ≤ 5mm.

[0016] In one embodiment, the height of the first seat is lower than the height of the second seat arranged around it in the vertical direction.

[0017] In one embodiment, the electrode assembly is provided in two sets, with the two sets of electrode assemblies arranged vertically at intervals, and the distance between the two sets of electrode assemblies is h, where 1mm≤h≤10mm.

[0018] In one embodiment, the line connecting the two first seats of one set of electrode assemblies intersects with the line connecting the two first seats of the other set of electrode assemblies.

[0019] In one embodiment, the fixing part is provided with a first fixing hole, and the first base is provided with a second fixing hole corresponding to the first fixing hole. The second fixing hole communicates with the inside and outside of the receiving cavity. The electrolysis device further includes an electrode post and a locking member. The electrode post passes through the first fixing hole and the second fixing hole. The locking member is disposed outside the housing and locks the electrode post to the first base to fix the fixing part.

[0020] In one embodiment, the housing includes an upper shell and a base, the upper shell and the base being detachably connected, the upper shell and the base forming the receiving cavity, the fixing seat being mounted on the base, and the inlet and the outlet being located on the upper shell.

[0021] The second technical problem mentioned above is solved by the following technical solution:

[0022] A gas-fired water heater, wherein the gas-fired water heater employs the electrolysis device described above.

[0023] Compared with the prior art, the gas-fired water heater of this utility model has the following advantages:

[0024] One end of the cantilever is secured by the fixing part fixed to the first base, and the other end is secured by the second base. This prevents the cantilever from vibrating continuously due to the impact of water flow and the action of bubbles generated by electrolysis. On the one hand, this reduces the possibility of the electrode assembly becoming loose, and on the other hand, it also prevents the possibility of different groups of electrode assemblies coming into contact with each other due to vibration, thus avoiding abnormal noise and short circuits caused by loosening.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] In the description of this utility model, it should be understood that the terms "vertical", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 based on the specific circumstances.

[0048] like Figure 1 , Figure 2 and Figure 8 As shown, this utility model provides an electrolysis device, which includes a housing 1, a fixing base group 2, and an electrode assembly 3. The housing 1 has a receiving cavity 11, and the housing 1 also has an inlet 12 and an outlet 13 communicating with the receiving cavity 11. The fixing base group 2 is disposed in the receiving cavity 11, and the fixing base group 2 includes a first base body 21 and a plurality of second base bodies 22. The first base body 21 and the second base bodies 22 are located on opposite sides of the inner sidewall of the receiving cavity 11. The electrode assembly 3 includes an electrode plate 30, and the electrode plate 30 includes a fixing part 301 and a plurality of cantilever arms 302. The plurality of cantilever arms 302 are arranged at intervals and connected to the fixing part 301. The fixing part 301 is fixed to the first base body 21, and at least a portion of the cantilever arms 302 are fixed to each of the second base bodies 22 at the ends away from the fixing part 301.

[0049] The fixing assembly 2 includes a first base 21 and a plurality of second bases 22. The plurality of second bases 22 are spaced apart from the first base 21, so that the fixing part 301 can be fixed to the first base 21. At least one end of the cantilever 302 away from the first base 21 is fixed to the second base 22. The cantilever 302 is effectively supported and fixed, so that when the water flow impacts the cantilever 302, one end of the cantilever 302 is stabilized by the fixing part 301 fixed to the first base 21, and the other end is stabilized by the second base 22. This avoids the vibration from being concentrated at a single point connection of the fixing part 301, thereby reducing the continuous vibration of the electrode plate 30 caused by the water flow impact and the action of bubbles generated by electrolysis. On the one hand, it reduces the possibility of the electrode assembly 3 loosening, and on the other hand, it reduces the possibility of different electrode plates coming into contact with each other due to vibration, thereby reducing the risk of abnormal noise and short circuit caused by loosening.

[0050] like Figure 2 , Figure 3 and Figure 9As shown, for ease of fixation, in some embodiments, the fixing part 301 is provided with a first fixing hole 303, and the first base 21 is provided with a second fixing hole 24 corresponding to the first fixing hole 303. The second fixing hole 24 communicates with the inside and outside of the receiving cavity 11. The electrolysis device also includes an electrode post 4 and a locking member 5. The electrode post 4 passes through the first fixing hole 303 and the second fixing hole 24. The locking member 5 is disposed outside the receiving cavity 11 and connected to the electrode post 4, thereby locking the electrode post 4 onto the first base 21 to fix the fixing part 301. The electrode plate 30 is fixed by its corresponding electrode post 4 and connected to the power supply through it. Thus, the electrode post 4 not only serves to connect the electrodes but also serves to fix them, thereby saving parts. Exemplarily, the electrode post 4 is a bolt-type electrode post with threads, and the locking member 5 is a nut, which is screwed onto the electrode post 4. The nut portion of the electrode post 4 can press the fixing part 301 onto the first base 21.

[0051] For example, in the current embodiment, the receiving cavity 11 is a circular cavity, and the fixing part 301 is arc-shaped to adapt to the inner cavity shape of the circular cavity and make more reasonable use of the internal space of the receiving cavity 11.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, in order to achieve sealing, a sealing groove 16 is provided on the outer wall of the housing 1, and the second fixing hole 24 passes through the bottom of the sealing groove 16. A first sealing ring 6 is provided in the sealing groove 16, and the first sealing ring 6 is fitted on the electrode post 4. A gasket 7 can also be fitted on the electrode post 4. The locking member 5 squeezes the gasket 7 and then squeezes the first sealing ring 6 to achieve the sealing effect, thereby preventing the receiving cavity 11 from communicating with the outside through the second fixing hole 24 and preventing the possibility of water leakage.

[0053] like Figure 8 and Figure 9 As shown, to facilitate fixing the cantilever 302, in some embodiments, the second base 22 is provided with a groove 23, and at least a portion of the cantilever 302 away from the fixing part 301 is embedded in the groove 23, thereby facilitating fixing and eliminating the need to open a connection hole on the cantilever 302 for connection, which is convenient for manufacturing and also saves costs. In the current embodiment, the groove 23 penetrates the second base 22 in the direction of the first base 21 opposite to it, so that the cantilever 302 can extend onto the first base 21.

[0054] It is understood that the electrode plate 30 generally includes a positive electrode plate 31 and a negative electrode plate 32, wherein the positive electrode plate 31 is used to connect the positive electrode and the negative electrode plate 32 is used to connect the negative electrode. Both the positive electrode plate 31 and the negative electrode plate 32 are respectively provided with a set of fixing bases 2, such as... Figure 8As shown, in some embodiments, the positive electrode plate 31 and the negative electrode plate 32 in the same electrode assembly 3 can be arranged side by side, or the positive electrode plate 31 and the negative electrode plate 32 in the same electrode assembly 3 can be arranged vertically with a gap between them.

[0055] like Figure 5 , Figure 6 and Figure 7 As shown, in the current embodiment, the cantilever 302 of the positive electrode plate 31 and the cantilever 302 of the negative electrode plate 32 in the same electrode assembly 3 are arranged alternately, that is, the positive electrode plate 31 and the negative electrode plate 32 are interlocked to further reduce the volume occupied, making the electrolysis device smaller and more suitable for miniaturization. Based on the above-mentioned form of the electrode assembly 3, two sets of fixing base groups 2 are also provided. The two first base bodies 21 in the two sets of fixing base groups 2 are spaced apart and opposite each other. In the two sets of fixing base groups 2, a plurality of second base bodies 22 in one set of fixing base groups 2 are spaced around the first base body 21 of the other set of fixing base groups 2 so as to fix the cantilever 302 of the interlocked positive electrode plate 31 and negative electrode plate 32.

[0056] For example, such as Figure 7 As shown, the positive electrode plate 31 has 5 cantilever 302, while the negative electrode plate 32 has 6 cantilever 302, so that the 11 cantilever 302 of the positive electrode plate 31 and the negative electrode plate 32 are staggered and spaced apart, and the outermost two cantilever 302 of the negative electrode plate 32 are not required to be supported by the second base 22.

[0057] In some embodiments, the electrode plate 30 may also be coated with a catalytic coating, so that it can generate not only oxygen, but also different other products. For example, an ozone-generating catalytic coating (metal oxide composite coating, which is prior art and will not be described in detail) may be coated on the positive electrode plate 31, so as to generate a certain amount of ozone for sterilization.

[0058] like Figure 6 As shown, in some embodiments, when the cantilever 302 of the positive electrode plate 31 and the cantilever 302 of the negative electrode plate 32 are arranged alternately, the distance between adjacent cantilever 302 of the positive electrode plate 31 and the cantilever 302 of the negative electrode plate 32 is L, 0.5mm≤L≤5mm. The specific distance can be customized according to the size of the receiving cavity 11, the water quality, different types and thicknesses of catalytic coatings, and the voltage. For example, when the water quality is good, a relatively small distance can be selected; when the coating is thick and the purity is high, a larger distance can be selected; when the voltage is high, a larger distance can be used.

[0059] like Figure 5 and Figure 9 As shown, in some embodiments, along the vertical direction (e.g.) Figure 3(As shown in the direction), the height of the first seat 21 is lower than the height of the second seat 22 surrounding it. When the fixing part 301 is fixed to the first seat 21, at least part of the cantilever 302 can be embedded between the adjacent second seats 22, further stabilizing the cantilever 302. In addition, by making the height of the first seat 21 lower than the height of the second seat 22 surrounding it, the top surface of the fixing part 301 and the top surface of the cantilever 302 can be flush with the top surface of the second seat 22, making the surface flatter and reducing unnecessary interference risks.

[0060] like Figure 3 and Figure 5 As shown, in some embodiments, the electrode assembly 3 is provided in two sets, with the positive electrode plate 31 and the negative electrode plate 32 in each set of electrode assembly 3 interlocked, along the vertical direction (e.g., ...). Figure 3 (As shown in the direction), the two sets of electrode components 3 are arranged vertically at intervals, that is, the electrode components 3 are divided into upper and lower layers, and the distance between the two sets of electrode components 3 is h, 1mm≤h≤10mm (e.g. Figure 4 (As shown). The specific spacing dimensions can be customized according to the size of the receiving cavity 11, the water quality, the type and thickness of different catalytic coatings, and the voltage level. For example, if the water quality is good and there are no concerns about impurities or iron filings, the distance can be relatively small; if the catalytic coating is thick, the electrode plate voltage is high, and the gas production of the electrode plate is large, a relatively larger spacing can be selected to prevent bubbles from clogging or stagnating between the layers.

[0061] In the current embodiment, based on the two sets of electrode components 3, the fixing base group 2 is provided in four groups, namely, four first bases 21 and a plurality of second bases 22 surrounding the four first bases 21 respectively; in order to accommodate the different heights of the two sets of electrode components 3, the height of the first base 21 and the second base 22 fixing the upper electrode component 3 is greater than the height of the first base 21 and the second base 22 fixing the lower electrode component 3.

[0062] It should also be noted that the positive electrode plate 31 and negative electrode plate 32 in the two sets of electrode assemblies 3 can be the same or different. In order to make reasonable use of space, in the current embodiment, the number of cantilever 302 in the upper electrode assembly 3 is greater than the number of cantilever 302 in the lower electrode assembly 3 (e.g., Figure 6 and Figure 7 As shown), the width of the upper electrode assembly 3 is greater than the width of the lower electrode assembly 3 (the spacing direction of the cantilever 302 is the width), so as to make the most of the space above and arrange as many cantilever 302s as possible to improve electrolysis efficiency.

[0063] When two sets of electrode assemblies 3 are installed, one set of electrode assemblies 3 can be intermittently idle while the other set of electrode assemblies 3 is activated to remove scale. Specifically, when one set of electrode assemblies 3 (e.g., set A) is energized, a large amount of OH- ions will be generated on the surface of its negative electrode plate 32 due to the hydrogen evolution reaction. - This creates a strongly alkaline microenvironment (pH can reach 11-12). At this time, calcium and magnesium ions in the water will rapidly form calcium carbonate and magnesium hydroxide scale on the surface of the negative electrode plate 32; when group A stops working (while group B starts working), the negative electrode plate 32 of group A no longer produces OH... - The high concentration of OH residue on its surface - It will rapidly diffuse into the surrounding water and be neutralized by the water's buffering system (such as bicarbonate). The pH value on the surface of the negative electrode plate 32 will return to near neutral (pH 7-8) within minutes. In a neutral pH environment, the solubility of newly formed scale (especially magnesium hydroxide) will increase significantly, and some scale that has not yet fully crystallized and has weak adhesion will dissolve on its own and return to the water. This is equivalent to providing the negative electrode with a "chemical rest period," preventing scale from continuing to grow and thicken in a strongly alkaline environment.

[0064] Furthermore, hydrogen bubbles continuously form on the surface of the negative electrode plate 32. As these hydrogen bubbles escape, they cover and "push up" the forming scale layer, resulting in a less than perfect contact between the scale and the negative electrode plate 32, leaving many tiny gaps. When the electrode assembly 3 is idle, hydrogen bubble generation ceases. The gas remaining in the scale gaps gradually escapes, and the scale layer undergoes a "venting" process, causing its volume to shrink slightly. Simultaneously, under its own weight and slight disturbance from water flow (if any), the scale layer is more likely to detach from the electrode surface, sinking to the bottom or being carried away by the water flow.

[0065] Furthermore, when energized, under the influence of an electric field, positively charged calcium ions (Ca) 2+ Calcium ions (Ca) will continuously migrate directionally towards the negative electrode plate 32, forming an "electrophoretic enrichment" effect. This is the key driving force for the continuous growth of scale on the surface of the negative electrode plate 32. When the electrode assembly 3 is de-energized, the electric field disappears. 2+ The directional migration of calcium ions immediately ceases. At this point, even if alkaline residue remains on the electrode surface, the lack of new calcium ions (Ca) means that the migration will stop. 2+ The limescale is continuously "pumped" in, depriving it of its raw material supply and preventing it from thickening further. This breaks the "positive feedback" cycle of limescale growth and reduces limescale formation.

[0066] Alternatively, the positive electrode plates 31 in the two sets of electrode assemblies 3 can be connected in parallel to the positive terminal of the power supply, while the two negative electrode plates 32 can be selectively connected to the negative terminal of the power supply via relays or similar means. This allows the two positive electrode plates 31 to operate continuously, while one of the two negative electrode plates 32 can rest, thus reducing only the operating time of the negative electrode plate 32. Both sets of positive electrode plates 31 will always operate simultaneously, continuously generating H. + This maintains a stable acidic environment in the water (pH 0.5-1.0), which effectively inhibits the crystallization of CaCO3 in the water. The high pH environment on the surface of the negative electrode plate 32 will naturally diffuse and neutralize, while the deposited scale will partially fall off or be washed away by the water flow.

[0067] Therefore, by setting up two or more sets of electrode assemblies 3, it is no longer necessary to perform polarity reversal operations, thereby reducing the formation of scale.

[0068] like Figure 8 and Figure 9 As shown, in order to further reduce the overall size, in some embodiments, the line connecting the two first seats 21 that fix one set of electrode components 3 intersects with the line connecting the two first seats 21 that fix another set of electrode components 3, so that the first seats 21 that fix different electrode components 3 are staggered, avoiding the electrode posts 4 used for fixing being located on the same straight line. While ensuring electrolysis efficiency, the size of the housing 1 is reduced, which is further suitable for miniaturization.

[0069] like Figure 2 As shown, in some embodiments, the housing 1 includes an upper shell 14 and a base 15, which are detachably connected to form a receiving cavity 11. The fixed seat assembly 2 is disposed on the base 15, while the inlet 12 and the outlet 13 are disposed on the upper shell 14. In order to prolong the residence time of water in the receiving cavity 11, the inlet 12 and the outlet 13 are set at an angle. In the current embodiment, the inlet 12 and the outlet 13 are set vertically.

[0070] Exemplarily, the upper shell 14 is fastened to the base 15, and a second sealing ring 8 is sandwiched between the upper shell 14 and the base 15 to reduce the possibility of water leakage. In the current embodiment, as Figure 9 and Figure 10 As shown, the inner wall of the upper shell 14 is provided with a first step 142, the outer wall of the base 15 is provided with a second step 152, the base 15 is inserted into the upper shell 14, and the second sealing ring 8 is clamped between the first step 142 and the second step 152.

[0071] like Figure 9 and Figure 10As shown, for ease of fixation, the outer periphery of the upper shell 14 is provided with a first fixing ear 141; the outer periphery of the base 15 is provided with a second fixing ear 151. Both the first fixing ear 141 and the second fixing ear 151 are provided with connecting holes, through which a connector can pass to fix the first fixing ear 141 and the second fixing ear 151. One of the connecting holes in the first fixing ear 141 and the second fixing ear 151 can be a screw hole, and the other is a through hole. The connector can be a screw or a bolt.

[0072] This utility model also provides a gas-fired water heater. The gas-fired water heater uses the above-mentioned electrolysis device, so that at least one end of the cantilever 302 away from the first base 21 is fixed to the second base 22. Thus, when the water flow impacts the cantilever 302, one end of the cantilever 302 is stabilized by the fixing part 301 fixed to the first base 21, and the other end is stabilized by the second base 22. This avoids continuous vibration of the cantilever 302 due to the impact of the water flow and the action of bubbles generated by electrolysis. On the one hand, it reduces the possibility of the electrode assembly 3 loosening, and on the other hand, it avoids the possibility of different groups of electrode assemblies 3 coming into contact with each other due to vibration, and avoids abnormal noise and short circuits caused by loosening.

[0073] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0074] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
