Domestic water dispenser with inlet/outlet water hardness monitoring function

Abstract

The invention discloses a domestic water dispenser with an inlet / outlet water hardness monitoring function. The domestic water dispenser comprises a water softening device which is used for softening and purifying inlet water, and a water distributor is arranged at the lower end of the water softening device. The domestic water dispenser further comprises a display device, a control signal generating device, a central controller, a central processing unit, a sampling device and a detecting device, wherein the control signal generating device is used for sending a starting signal to the central controller, and the central controller responds the starting signal to control the display device, the central processing unit, the sampling device and the detecting device to work. As water quality is analyzed in real time and detection results are displayed on the display device, perceptual intuition and visuality convenience is brought to a user.

Description

technical field [0001] The invention relates to a household water dispenser with the function of monitoring the hardness of the inlet and outlet water and a method for monitoring the hardness of the inlet and outlet water of the household water dispenser. Background technique [0002] At present, many household water softeners do not have a water quality monitoring function. Users cannot clearly understand the water quality of the incoming water and the softening effect of the outgoing water. The regeneration cycle of the water softener varies depending on the area of ​​use, and it is difficult for users to know whether resin regeneration is required. Although some water softeners have added hardness monitoring function, they basically use TDS detection alone, but TDS detection can not fully reflect the hardness index of water quality. The softening of water quality in water softeners uses sodium ions to replace calcium and magnesium ions. The TDS value will not change sign...

Problems solved by technology

[0002] At present, many household water softeners do not have a water quality monitoring function. Users cannot clearly understand the water quality of the incoming water and the softening effect of the outgoing water. The regeneration cycle of the water softener varies depending on the area of ​​use, and it is difficult for users to know whether resin regeneration is required

Although some water softeners have added hardness monitoring function, they basically use TDS detection alone, but TDS detection can not fully reflect the hardness index of water quality. The softening of water quality in water softeners uses sodium ions to replace calcium and magnesium ions. The TDS value will not change significantly, so it cannot be used for water softener detection

At the same time, pH, electrolytic ions, etc. will also affect the test results of TDS, resulting in inaccurate test results. However, the titration and colorimetry methods used to test water hardness generally require high professionalism of equipment and personnel. Troublesome and obviously not suitable for use in the user's home

The water softening treatment system used in some factories uses ion detection electrodes to conduct online real-time detection of water quality, but the electrodes are soaked in a large amount of detection water for a long time, the life is very short, and the replacement of electrodes is costly and cumbersome. This method is obviously not suitable for household soft water machine
