Auto-regenerable hot and cold water softener

Abstract

Disclosed is an automatic regenerable cold / hot water softener comprising a water softening tank having ion exchange resin and a regenerating tank filled with regenerating substance of the ion exchange resin. The water softener controls water softening mode for receiving raw water and discharging soft water using one switching valve, a direct water mode for discharging raw water itself, a regeneration mode for regenerating ion exchange resin, and a intermittence mode for intermitting the inflow and outflow of the raw water and the soft water. The precise regeneration time of the ion exchange resin is judged according to the used amount of the soft water by a temperature sensor and a flow meter for sensing temperature and flux of supply raw water. The regeneration is automatically prosecuted by a control part having a microprocessor. Enough cold / hot soft water can be supplied according to season or need of a user. The cold / hot water softener serves a user's convenience in that sudden change of temperature is prevented.

Description

technical field [0001] The present invention relates to a cold / hot water softener with temperature subdivision and automatic regeneration function, more specifically, relates to a cold / hot water softener with automatic regeneration, which is used to separately control the Water softening mode for opening and closing valve to discharge soft water, regeneration mode for regenerating ion exchange resin, direct water mode for discharging raw water itself, and interruption mode for interrupting raw water and interrupting inflow and outflow of soft water, by Automatically detect the regeneration time of the ion exchange resin to automatically regenerate the ion exchange resin without special additional operations, and automatically discharge soft water with low and subdivided temperatures, thereby bringing convenience to users. Background technique [0002] Usually, the principle of water softener is to use Na + Ion replacement of Ca in hard water 2+ Ions and Mg 2+ ions to soft...

AI Technical Summary

Problems solved by technology

[0010] However, the traditional cold / hot water softeners mentioned above have some disadvantages

First, it is difficult to determine the regeneration time of the ion exchange resin contained in each cold / hot water softening tank 4a, 4b, thus, its determination depends entirely on the user's feeling

Therefore, the performance and service life of the ion exchange resin is greatly reduced due to unnecessarily frequent or infrequent regeneration

[0011] Second, as mentioned above, since the ion exchange resin regeneration steps in conventional cold / hot water softeners are too complicated, it takes a long time even for skilled personnel

In particular, since all processes of regeneration need to be directly operated manually by the user each time, this causes a disadvantage that very troublesome labor is required.

[0012] Third, since multiple valves V1, V2, V3, V4, V5, V6 are included in the use of the cold / hot water softener, its structure is complicated, it may cause failure and failure, and its manufacturing cost is expensive
