Problems solved by technology

[0013] Compared with water softening devices using ion exchange resins, the above-mentioned water softening devices using CDI are expensive, and the amount of water they treat is relatively small, so they are not preferable in washing machines that require a large amount of water to be supplied quickly
[0014] The washing machine having the above water softening device softens the water supplied from the water supply source, then mixes the obtained softened water with detergent, and then supplies the water mixed with the detergent into the tub, thereby degrading the water softening performance
In addition, the water supply time of these washing machines is longer than the detergent supply time, so that the water that will be mixed with the detergent supplied from the detergent supply unit and then directly supplied to the tub does not dissolve the detergent in the water, thus reducing the dissolution of the detergent. sex

Abstract

The invention relates to a washer with water-softening device which improves the solubility as well as water-softening performance of detergent. The washer comprises: a container; a water supply device for supplying water to the container; a detergent supply device for supplying detergent to the container; a water-softening device for softening water. The water-softening device is set to mix water in the water supply device with detergent in the detergent supply device, and water mixed with the detergent can be supplied to the water-softening device.

Description

Technical field [0001] The present invention relates to a washing machine, and more specifically, to a washing machine with a water softening device. Background technique [0002] Generally, water (especially groundwater) contains a large amount of minerals, such as calcium, magnesium and the like. The value obtained by digitizing the total amount of calcium, magnesium, etc. is called hardness. Water with high hardness is called hard water, and water with low hardness is called soft water. [0003] When hard water (ie, water with high hardness) is used to make tea, the taste of tea is bitter. In addition, when hard water flows in the pipe, the hard water generates scale on the inner surface of the pipe, thereby reducing heat transfer performance and fluidity of the fluid. In the case where the scale is not regularly removed, the pipeline will be damaged. [0004] In addition, when hard water is used in a washing machine, the hard water reacts with soap and therefore reduces the w...
