Detailed Description
Fig. 1 is a schematic structural view of an integrated water softener 100 according to an embodiment of the present invention. Fig. 3 is a schematic view of an image captured by the light sensing condition detecting apparatus 500 of the water softener 100 shown in fig. 1. Fig. 4 is a schematic view of a control plate 400 and a display plate 700 of the water softener 100 according to one embodiment of the present invention. The water softener 100 of the embodiment of the present invention includes: a resin filter box 200, a salt box 300, a light source 900, a photosensitive condition detecting device 500, a control board 400 and a display panel 700. The resin filter box 200 has a water inlet, a water outlet and a salt water inlet, an ion exchange resin 210 is arranged in the resin filter box 200, and water to be treated enters the resin filter box 200 from the water inlet and is discharged out of the resin filter box 200 from the water outlet after being treated by the ion exchange resin 210.
The ion exchange resin 210 may be a sodium type cation exchange resin. When hard ions such as calcium and magnesium in water to be treated (hard water) flow into the resin filter box 200, they are adsorbed by the ion exchange resin 210 to soften the water and turn it into soft water. When all the ion exchange resins 210 are fully adsorbed with calcium, magnesium and other ions, the ion exchange resins 210 are in a saturated adsorption state and hard water softening cannot be continued, and at this time, the ion exchange resins 210 need to be subjected to reduction regeneration treatment.
The reductive regeneration of the ion exchange resin 210 in the resin filter box 200 of the water softener 100 according to the embodiment of the present invention is performed using a high concentration brine. The salt tank 300 is filled with salt at the bottom, and at least a portion of the salt is dissolved in water to form a high-concentration brine, which is used to regenerate the ion exchange resin 210 of the water softener 100. After the brine in the salt tank 300 is pumped into the resin filter tank 200, it is necessary to replenish the same amount of water in time for the next use. The light source 900 is disposed at an upper portion of the salt box 300 for illuminating the inside of the salt box 300. The photosensitive condition detection device 500 is disposed in the salt box 300 and is configured to collect an image of an illumination distribution condition in the salt box 300. The control board 400 is configured to calculate the remaining salt amount m of the water softener 100 based on the image obtained by the light sensing condition detecting means 500. The display panel 700 is disposed on the outer side of the water softener 100 for displaying the remaining salt amount m. The water softener 100 of the embodiment of the invention collects the image of the illumination distribution condition in the salt box 300 by arranging the photosensitive condition detection device 500, the control panel 400 calculates the residual salt amount of the water softener 100 based on the image and displays the residual salt amount by the display panel 700, so that the residual salt amount of the water softener 100 can be simply, accurately and timely obtained, and the use experience of a user is improved.
The salt tank 300 is formed with an air region, a brine region, and a salt region in this order from top to bottom. The thicknesses of the air region, the saline water region, and the salt region are varied according to the input or output of saline water in the salt box 300 or the remaining amount of salt in the salt box 300. It can be understood that as brine is drawn from the salt tank 300 into the resin filter tank 200, the air region is increasingly thickened and the brine region is increasingly thinned as brine is continuously drawn away. In replenishing the salt tank 300, the air region becomes thinner and the brine region becomes thicker due to the increase of water, and the salt region becomes thinner due to the dissolution of the salt in the salt tank 300. In some embodiments, the photosensitive condition detecting device 500 of the water softener 100 according to the embodiment of the invention is vertically disposed in the salt tank 300, and the bottom thereof contacts the bottom of the salt tank 300; the light sensing condition detection means 500 is used at least for acquiring images of salt regions. By vertically arranging the photosensitive condition detection apparatus 500 and placing the bottom thereof against the bottom of the salt box 300, data processing can be made simpler.
The light sensing condition detecting apparatus 500 includes, but is not limited to, a charge coupled device image sensor (CCD) area array, a Complementary Metal Oxide Semiconductor (CMOS) area array, a photo-resistor area array, a line array photodetector, and the like. As shown in fig. 3, it is a schematic diagram of an image collected by the light sensing condition detecting device 500 of the water softener 100 shown in fig. 1. When salt is in the salt tank 300, the light source 900 is turned on, and the salt blocks the lower portion of the sensing condition detecting device 500, so that the portion cannot detect light, i.e., a non-light area. The other part of the photosensitive condition detecting device 500 is not blocked by non-light-transmitting substances and can be normally photosensitive, i.e. an illumination area. It can be understood that when the non-illuminated area is not rectangular, the control board 400 will automatically correct it to form a rectangle with the same size as the original area.
In some embodiments, the water softener 100 of the present embodiment further includes: and the temperature sensor 600 is arranged in the salt box 300 and used for detecting the temperature of the salt water to obtain the temperature t of the salt water.
The control board 400 of the embodiment of the present invention includes: a storage module 401 and a data processing module 402. The storage module 401 is configured to store the photosensitive width L of the photosensitive condition detection device, the floor area S occupied by the salt, the density ρ of the salt, and the water density ρ corresponding to the numerical range of the brine temperaturetThe height h of the standard liquid level of the brine and the solubility s (t) of the salt corresponding to the temperature range of the brine. The data processing module 402 is configured to calculate the area S of the non-illuminated region in the imageFAnd calculating the residual salt amount m according to the following formula:
Figure BDA0002070295400000051

The water softener 100 of the embodiment of the invention also detects the temperature t of the brine in real time, and can accurately calculate the residual salt amount m. The height h of the standard level of the brine refers to a height of the brine in the water softener 100 at a set standard level.
In a preferred embodiment, the control board 400 of the present embodiment further includes: and the reminding module 403 is configured to send out a salt adding signal when the remaining salt amount m is less than or equal to a preset remaining salt amount threshold. The specific value of the preset residual salt amount threshold can be determined according to the statistical result of experimental data. Meanwhile, the display panel 700 may be further configured to display the salt signal. When the water softener 100 provided by the embodiment of the invention is used, a user can simply and immediately check the current residual salt amount and the salt adding signal of the water softener 100, and the user can add salt in time according to the information, so that the water quality is ensured, and the requirements of people on bathing, cleaning and the like are met.
In some embodiments, the storage module 401 is further configured to store: the rated water production amount f (Y) of each liter of ion exchange resin 210 and the salt consumption amount m of each liter of ion exchange resin 210 during single regeneration corresponding to the numerical range of the brine temperaturez(t) and the resin volume V of the ion exchange resin 210Tree (R)(ii) a The data processing module 402 is further configured to calculate the remaining water production amount V and/or the remaining regeneration number n according to the following formula, wherein:

In addition to displaying the remaining salt amount m, the water softener 100 according to the embodiment of the present invention may also check the remaining water production amount V and the remaining regeneration number n in real time. In addition to the residual salt amount m, the residual water production amount V and the residual regeneration number n are important parameters of the water softener 100, and therefore, the water softener 100 according to the embodiment of the present invention is configured to accurately calculate and display the residual water production amount V and the residual regeneration number n.
The reminding module 403 may be further configured to send a salt adding signal when the remaining water making amount V is less than or equal to a preset remaining water making amount threshold; and/or sending a salt adding signal when the residual regeneration number n is less than or equal to a preset residual regeneration number threshold value.
