Water softener and water supply method thereof

Abstract

The invention provides a water softener and a water supply method thereof. The water softener includes a water storage tank and a water softening module. The water storage tank is configured as below: in the state of water usage, the water storage tank supplies part or all of the water to the outside; the water softening module is configured as below: in the state of water usage, when the first TDS index of the water in the water storage tank exceeds a preset first TDS threshold value, the water softening module starts to produce soft water, and supplies water to the outside together with the water storage tank. In the state of water usage, the water softener first uses the soft water in the water storage tank for water supply; the water storage tank is being filled with tap water while water supply to the outside. When the TDS of the water in the water storage tank exceeds the certain threshold, the water softening module starts a work cycle, and supplies the water as supplement to the outside together with the water in the water storage tank. Thus, the present invention can ensure the water quality, and provides adequate water to users as possible.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water softener and a water supply method for the water softener. Background technique [0002] Large numbers of the world's population live in countries with severe shortages of sanitary drinking water. A high percentage of these people live in rural and remote areas where few municipal drinking water treatment plants exist. People have to depend directly on surface water sources such as wells, ponds and rivers. Water from these sources can contain high levels of dissolved salts on the order of 500-3000 ppm, making the water unsuitable for drinking purposes. Water with a salt content in the order of 500-1500 ppm has an unpleasant taste, and water with a salt content in excess of 1500 ppm is often referred to as "brackish water" and is relatively unpalatable. Some water softeners are available to treat the water from these sources so that the water from these sources ...

AI Technical Summary

Problems solved by technology

[0003] However, after the existing water softening equipment produces water for a period of time, it needs to perform regeneration treatment to improve its soft water performance. When the existing water softening equipment performs regeneration treatment, the water production needs to be interrupted, that is to say, the existing water softening equipment cannot Continuous water production, so that uninterrupted water supply cannot be achieved
