Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to fall within the scope of the utility model. Furthermore, it should be understood that the detailed description is provided for the purpose of illustrating and explaining the present utility model only, and is not to be construed as limiting the utility model, and that the terms "first", "second", etc. are merely used for convenience of description and are not to be construed as indicating or implying a relative importance or implying a number of technical features indicated, whereby the features defining "first", "second", etc. may explicitly or implicitly include one or more features.

Referring to fig. 1, an embodiment of the present utility model provides a novel water softener, which includes a softening device 1, and a water inlet pipeline 2, a water outlet pipeline 3 and a regeneration pipeline 4 which are in fluid communication with the softening device 1; the water inlet pipeline 2 can convey hard water to be treated to the softening device 1, and soft water meeting the requirements is discharged from the water outlet pipeline 3 after the hard water is softened by the softening device 1; when the softening capacity of the softening device 1 decreases after a period of operation, the softening device 1 needs to be subjected to regeneration treatment, that is, the softening device 1 is backwashed by a regeneration device (such as a brine tank, not shown) in the water softener, and at this time, brine provided by the regeneration device can enter the softening device 1 from a regeneration pipeline 4 to perform flushing regeneration treatment on the softening device 1; a sewage drain 5 may be additionally provided in communication with the softening device 1, and the sewage generated by the regeneration treatment may be discharged through the sewage drain 5. The softening device 1 includes, but is not limited to, a common softening structure such as a resin barrel and a resin tower, which are conventional in the art, and the description of this embodiment is omitted.

In this embodiment, the first gate valve 6 is disposed on the water inlet pipeline 2, the second gate valve 7 is disposed on the regeneration pipeline 4, and the on-line hardness detection device 8 is mounted on the water outlet pipeline 3, wherein the first gate valve 6 and the second gate valve 7 are both connected with the on-line hardness detection device 8, so that the on-line hardness detection device 8 can output a hardness leakage signal to control the switching of the first gate valve 6 and the second gate valve 7 once the hardness leakage is detected by the on-line hardness detection device 8.

Specifically, when the hardness on-line detection device 8 does not detect the hardness leakage, the first gate valve 6 is opened, and the second gate valve 7 is closed, so that the water inlet pipeline 2 can send hard water to be treated into the softening device 1 for softening treatment; when the hardness on-line detecting device 8 detects the hardness leakage, the hardness on-line detecting device 8 outputs a hardness leakage signal to control the first gate valve 6 to be closed and the second gate valve 7 to be opened, so that the softening device 1 is subjected to flushing and regenerating treatment through the regenerating pipeline 4. As an alternative embodiment, the hardness online detection device 8 in this example automatically detects the hardness of water quality by colorimetry.

The hardness on-line detection device 8 is connected with a controller 9 or a timer 10, and the hardness on-line detection device 8 is controlled by the controller 9 or the timer 10 to carry out hardness detection at a set frequency according to the actual running condition of the water softener during use, so that the regeneration period can be controlled more scientifically and effectively. In view of the relative tendency of the softening device 1 to develop hardness leakage in the early and late stages of regeneration, the controller 9 or timer 10 preferably controls the hardness in-line detecting device 8 to detect a plurality of times during the period of time before and after the period of time expected to be regenerated. For example, the hardness online detection means 8 may be set to perform hardness detection at a frequency of 20 min/time in the preceding hour in which regeneration is expected and in the one hour after regeneration, and the remaining period may be adjusted to a detection frequency of 8 h/time.

When the device is used for the first time, a reasonable regeneration time and detection frequency can be set by using the controller 9 or the timer 10 through theoretical calculation; after a period of use is determined, the regeneration period and the detection frequency are reset. In the regeneration operation, the approximate regeneration time may be calculated based on the size of the softening device 1, the resin amount, and the like, and the regeneration time of the softening device 1 may be adjusted by the controller 9 or the timer 10.

Further, when the hardness online detector 8 is connected to the controller 9, it is also possible to store the hardness leak period of the softening device 1 with the controller 9 and judge the resin replacement time of the softening device 1. For example, when the accumulated number of hardness leaks exceeds the set number, or when the hardness leak period is smaller than the set period, the controller 9 judges that the resin in the softening device 1 needs to be replaced and issues an alarm signal to prompt.

The principles and embodiments of the present utility model have been described herein with reference to specific examples, the description of the above examples is only for aiding in understanding the technical solution of the present utility model and its core ideas; those of ordinary skill in the art will appreciate that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the utility model.
