Description

Technical Field

[0001] This utility model belongs to the technical field of water heater equipment, specifically relating to an electrolytic water generator and a water heater. Background Technology

[0002] Tap water contains a large amount of calcium. 2+ Mg 2+ Cl - SO4 2- Plasma, during the use of water heaters, these ions can deposit and form solids inside the heater, thus affecting the heating efficiency and lifespan of the water heater. In addition, some high-end water heaters now include electrolysis devices to electrolyze the water in the heater to create hydrogen- and oxygen-rich water.

[0003] There are two common configurations in existing water heaters, but both have certain problems. The first type only has an electrolysis device, which directly electrolyzes tap water when it is working. This can lead to rapid scaling and corrosion in the electrolysis area, and may produce side reactions or even toxic substances. The second type integrates the electrolysis device and the filtration device in the same location in the valve assembly. For example, Chinese Patent 202521272516.1 discloses an electrolysis generator and hot water equipment for supplementing minerals, which includes a shell, a mineral filter element, and an electrode module. The mineral filter element and the electrode module are connected to the shell from both ends and operate in a common cavity formed by the shell. In this case, only a small portion of the water is filtered before being electrolyzed. Most of the unfiltered water still forms scale and other deposits at the electrolysis electrodes, covering the electrode plates and ultimately affecting the electrolysis effect and water quality.

[0004] Therefore, it is necessary to design an electrolysis device that can take into account both electrolysis and filtration effects. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an electrolyzed water generator with good filtration and electrolysis effects, and a water heater using the device.

[0016] Preferably, the purification device includes a filter assembly and a water purification substance disposed within the filter assembly. The filter assembly has multiple filter holes.

Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "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 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 limiting this utility model.

[0029] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0030] In current water heaters, the electrolysis device and the filtration device are integrated into the same end. In this case, the electrolysis device and the filtration device share a cavity. At this time, some water flows out without being filtered or electrolyzed, some water is electrolyzed without being filtered, and some water is filtered before being electrolyzed. In other words, the filtration effect and the electrolysis effect are both poor. During the short flow time, the slow-release ions of the scale inhibitor in the filter device cannot effectively disperse and chelate with the calcium and magnesium ions in the water in a short time, so it cannot achieve the scale inhibition effect, nor can it enhance the subsequent electrolysis.

[0031] Please refer to Figures 1-4This utility model provides an electrolytic water generator 1, which includes a device body 10, an electrolytic water module 20, and a water purification module 30. The electrolytic water module 20 and the water purification module 30 are respectively disposed at both ends of the device body 10, and the device body 10 separates the electrolytic water module 20 and the water purification module 30. It can be understood that the device body 10 integrates the electrolytic water module 20 and the water purification module 30 together and simultaneously separates them at both ends. The electrolytic water module 20 and the water purification module 30 are not connected in the water circuit within the electrolytic water generator 1, but are respectively connected to external pipelines and water heater pipelines.

[0032] The water purification module 30 includes a purification chamber 201 and a first water inlet 202 and a second water inlet 203 connected to the purification chamber 201. The first water inlet 202 is used to connect to an external pipe, and the second water inlet 203 is connected to a water heater pipe. A purification device 204 is installed inside the purification chamber 201.

[0033] The water electrolysis module 20 includes an electrolysis chamber 301 and a first outlet 302 and a second outlet 303 connected to the electrolysis chamber 301. The first outlet 302 is used to connect to an external pipe, and the second outlet 303 is connected to a water heater pipe. An electrolysis device is installed inside the electrolysis chamber 301. It can be understood that the first inlet 202 of the water purification module 30 is connected to an external pipe to guide water from the external pipe to the water electrolysis generator 1, while the second inlet 203 guides the water treated by the purification device 204 into the water heater. The second outlet 303 of the water electrolysis module 20... The system connects to the water heater pipes. After water purification and heating, the water undergoes an electrolysis reaction in the electrolysis chamber 301, forming hydrogen-rich and oxygen-rich water. Users can then use this freshly electrolyzed hydrogen-rich and oxygen-rich water. Meanwhile, the incoming water first passes through the water purification module 30, which continuously treats the incoming water and the water inside the water heater. Substances such as scale inhibitors release slow-release ions through their own release. These ions interfere with and inhibit the combination and precipitation of calcium and magnesium ions with anions (such as carbonate and sulfate ions) in the water. The slow-release ions not only play a role in the water quality optimization chamber, but can also enter the water tank or inner tank through the water path to continuously optimize the water quality.

[0034] Please refer to Figures 1-4 In this embodiment, the water electrolysis module 20 further includes a receiving cover 205. The electrolysis chamber 301 is open at one end facing the receiving cover 205. The receiving cover 205 is detachably connected to the electrolysis chamber 301 to seal the electrolysis chamber 301. Exemplarily, the receiving cover 205 can be integrally molded from an insulating material. The receiving cover 205 is used to seal the electrolysis chamber 301 to prevent water leakage. Simultaneously, the receiving cover 205 and the electrolysis chamber 301 are detachably connected, facilitating replacement or maintenance of the electrolysis device. Specifically, the receiving cover 205 and the electrolysis chamber 301 can be connected by a threaded seal or a screw / bolt seal, etc.

[0035] Please refer to Figures 1-4 In this embodiment, the lower end of the receiving cover 205 is provided with a first connecting portion 206 extending toward the electrolysis chamber 301. At least one first sealing ring 207 is fitted onto the first connecting portion 206. When the receiving cover 205 is connected and fixed to the electrolysis chamber 301, the first connecting portion 206 extends into the electrolysis chamber 301, and the first sealing ring 207 seals the connection between the receiving cover 205 and the electrolysis chamber 301. It can be understood that when the first connecting portion 206 is inserted into and connected to the electrolysis chamber 301, the first sealing ring 207 is press-fitted at the connection between the receiving cover 205 and the electrolysis chamber 301, achieving a watertight structure at the connection.

[0036] Please refer to Figures 1-4 In this embodiment, the electrolysis device includes an electrode assembly 208, a fastening assembly 209, and a transmission line 210. The electrode assembly 208 is disposed within the electrolysis chamber 301. A connection hole 211 communicating with the electrolysis chamber 301 is provided on the receiving cover 205. The first end of the fastening assembly 209 extends into the electrolysis chamber 301 through the connection hole 211 and is fixedly connected to the electrode assembly 208. The second end of the fastening assembly 209 is disposed on the outside of the receiving cover 205 and is fixedly connected to the transmission line 210. The fastening assembly 209 is made of conductive material. It is understood that the transmission line 210 is electrically connected to the electrode assembly 208 through the fastening assembly 209. The fastening assembly 209 can be installed on the receiving cover 205 by bolts or plastic coating. In use, the circuit is connected to the electrode assembly 208 through the transmission line 210 and the fastening assembly 209 to supply power to the electrode assembly 208. This achieves power supply to the electrode assembly 208 within the sealed chamber, preventing short circuits or leakage safety issues.

[0037] Furthermore, the electrolysis chamber 301 is provided with a mounting base 212 corresponding to the fastening assembly 209, and the electrode assembly 208 is provided with a fixing hole 213 corresponding to the fastening assembly 209. When the fastening assembly 209 extends into the electrolysis chamber 301, it passes through the fixing hole 213 and is fixedly connected to the mounting base 212 to fix the electrode assembly 208. It can be understood that after the fastening assembly 209 passes through the electrode assembly 208, it is fixedly connected to the mounting base 212 of the electrolysis chamber 301, which can fix the position of the electrode assembly 208 in the electrolysis chamber 301 and avoid the risk that the electrode assembly 208 will not function properly due to water flow impact. For example, the fastening assembly 209 may include a bolt structure, and the mounting base 212 is provided with corresponding threads, so that the two achieve a detachable fixed connection.

[0038] Please refer to Figures 1-4In this embodiment, the water purification module 30 further includes a sealing cover 304. The purification chamber 201 is open at one end facing the sealing cover 304, and the sealing cover 304 is detachably connected to the purification chamber 201 to seal the purification chamber 201. Exemplarily, the sealing cover 304 and the purification chamber 201 can be connected by a threaded seal or a screw bolt seal, etc. The detachable nature of the sealing cover 304 facilitates the replenishment or replacement of the purification device 204, extending its service life.

[0039] Furthermore, the lower end of the sealing cover 304 is provided with a second connecting portion 305 facing the purification chamber 201. At least one second sealing ring 306 is fitted onto the second connecting portion 305. When the sealing cover 304 is connected and fixed to the purification chamber 201, the second connecting portion 305 is connected to the upper part of the purification chamber 201, and the second sealing ring 306 seals the connection between the sealing cover 304 and the purification chamber 201. It can be understood that when the sealing cover 304 is connected to the purification chamber 201, the second sealing ring 306 is located at the connection between the sealing cover 304 and the purification chamber 201, and the second sealing ring 306 is interference-fitted with both to achieve a watertight structure of the purification chamber 201 and prevent leakage.

[0040] Please refer to Figures 1-4 In this embodiment, the purification device 204 includes a filter assembly 307 and a water purification substance disposed within the filter assembly 307. The filter assembly 307 has multiple filter holes 308. When water flows into the purification chamber 201 from the first inlet 202, the water first passes through the filter assembly 307 and the water purification substance before flowing out from the second inlet 203. It is understood that when water flows into the purification chamber 201 from the first inlet 202, it passes through the filter assembly 307, and the water purification substance is slowly released into the water flow to purify the water. The purified water then enters the water heater, and the slowly released water purification substance also enters the water heater, maintaining the water purification effect for a long time.

[0041] Furthermore, the water purification substance is one or more of a scale inhibitor and a residual chlorine remover. For example, scale inhibitors may include organophosphates (ATMP, HEDP, PBTC), polycarboxylate / polymers (PAA, AA / AMPS copolymers), environmentally friendly types (PESA, PASP), natural polymers (lignin sulfonates, tannic acid), etc.; residual chlorine removers include reducing agents (NaHSO3, Na2S2O3), adsorbents (granular activated carbon), and special resins (Fe-loaded...). 2+ Modified resins, etc.

[0042] Please refer to Figures 1-5This utility model embodiment also provides a water heater, which includes a water heater body 40 and an electrolytic water generator 1 as described above. The water heater body 40 includes an inlet end 401 and an outlet end 402. The inlet end 401 is fixedly connected to the second inlet 203, and the outlet end 402 is fixedly connected to the second outlet 303. When the electrolytic water generator 1 is working, the water that has passed through the water purification module 30 enters the water heater body 40. The water that has been heated by the water heater body 40 is electrolyzed by the electrolytic water module 20 and flows out from the first outlet 302.

[0043] The electrolytic water generator 1 in this solution can purify the water before it enters the water heater and maintain the water quality treatment effect in the water heater tank. Electrolytic water treatment is performed at the water outlet 402 of the water heater, avoiding problems such as scale deposition in the water heater tank and at the electrolysis end. Users can use hydrogen-rich and oxygen-rich safe water, resulting in a good user experience.
