Description

[Technical field]

[0001] The invention relates to a water softening device. [Background technology]

[0002] A dishwasher is a device that automatically washes bowls, chopsticks, plates, dishes, knives, forks and other tableware, and the water softener is an important component of the dishwasher. Figure 1 As shown, the existing water softener usually takes in water through a breather 20. There are two water paths inside the water softener. One path leads to the soft water chamber, and the hardness components such as calcium and magnesium ions in the water are exchanged with the sodium ions on the resin in the soft water chamber. In this way, the hardness components such as calcium and magnesium ions in the water are adsorbed on the resin to soften the water, thereby avoiding the scaling phenomenon of carbonate in the dishwasher tank; the other path leads to the salt chamber, and a channel that can connect the salt chamber and the soft water chamber is provided between the salt chamber and the soft water chamber. The side of the water softener is also provided with a solenoid valve 30 for controlling the opening and closing of the channel. When the resin absorbs a certain amount of hardness components such as calcium and magnesium ions, the solenoid valve 30 can be started to allow the salt water in the salt chamber to flow into the soft water chamber to rinse the resin, so that the hardness components such as calcium and magnesium ions on the resin are replaced and discharged from the water softener with the regenerated waste liquid. The resin then resumes its softening exchange function, and the water path is switched by the solenoid valve 30. However, some dishwashers do not require a breather due to cost and design requirements, and existing water softeners can only use a single mode of water intake by the breather 20 and control by an external solenoid valve 30, which cannot meet the needs of some customers.
