Description

Technical Field

[0001] This utility model relates to the field of water treatment, and in particular to an electrolysis component with sterilization function, which electrolyzes brine to produce sodium hypochlorite, a sodium hypochlorite generator having the electrolysis component, and a water softener having the sodium hypochlorite generator. Background Technology

[0002] With societal development, water softeners are becoming increasingly common. Household water softeners typically use cation exchange resin as the softening material. The resin surface has many pores, making it prone to bacterial growth and resin contamination in humid and sealed environments, thus affecting the health of the water used. Many household water softeners on the market lack sterilization or disinfection devices, and replacing the resin is costly, requiring the addition of chemical agents which leaves chemical residues and is inconvenient. Water softeners should ideally be equipped with sterilization devices and avoid these problems.

[0003] In industrial water softening systems, sodium hypochlorite generators are commonly used for sterilization. These generators electrolyze brine to produce sodium hypochlorite, which has strong oxidizing properties and thus acts as a disinfectant. However, existing sodium hypochlorite generators in commercially available water softeners have the following shortcomings that need to be addressed.

[0004] 1. Most of the sodium hypochlorite generators in existing water softeners on the market have cylindrical electrodes with small diameters, resulting in a small effective electrolysis area and insufficient sodium hypochlorite concentration for sterilization.

[0005] 2. The control system is integrated with the machine in an enclosed space, resulting in poor heat dissipation. Especially after increasing the effective electrolysis area, the temperature exceeds 85 degrees Celsius. In a confined space, the temperature will be even higher, which may cause components to age and even pose a fire risk.

[0006] 3. The electrolysis unit operates in a high-humidity environment, which can easily cause oxidation of metal parts and affect equipment performance. Therefore, the control system needs to have an additional sealing structure in humid environments to adapt to different installation scenarios.

[0007] 4. The control system and electrolysis components need to be easily disassembled and replaced to reduce maintenance costs.

[0008] Chinese patent CN221275901U discloses an electrolytic brine generator. A salt valve is connected to the inlet, and a control valve is connected to the outlet. The salt valve draws in salt, which enters the brine passage through the inlet. The brine in the passage is electrolyzed by electrodes to produce sodium hypochlorite. The sodium hypochlorite is discharged through the outlet to the control valve for resin disinfection. This structure is simple and easy to install in a water softener. The outer casing has an installation channel, and the electrolysis bracket with the electrodes is detachably connected to this channel. When the electrodes are severely worn, they can be replaced promptly to ensure electrolysis efficiency and improve resin disinfection without replacing the entire electrolytic brine generator, thus reducing maintenance costs. This design uses cylindrical electrodes, which increases the effective electrolysis area, but the effect is limited. Further increasing the diameter of the cylindrical electrodes would increase the volume of the electrolysis assembly, hindering miniaturization.

[0009] Chinese patent CN207498106U discloses a miniature disinfection device for a water softener, comprising a tube body. The inner wall of the tube body has two electrodes positioned opposite each other. Electrode one is connected to the positive terminal of a power supply via a power cable, and electrode two is connected to the negative terminal via a power cable. A quick connector is connected to each end of the tube body. This disinfection device is small in size, suitable for water softener installations with limited space. It allows for quick connection and plug-and-play operation, enabling rapid connection of liquid inlet and outlet pipes, effectively improving assembly and production efficiency and saving costs. While this design reduces the size of the electrolysis components and facilitates disassembly and assembly, the brine flow area is relatively small, limiting the effective electrolysis area.
