[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0033] Figure 1 Schematic diagram of the structure of a water softener according to an embodiment of the present application. Figure 1 As shown, the water softener includes a control valve assembly, a resin tank assembly and a flow meter, etc. The control valve assembly has a main control board, a flow detection module and a water circuit switching module. The control valve assembly can switch the water circuit through flow triggering, time setting and manual operation under program setting conditions. The switching water circuit described in the present invention is that the water circuit system in the machine needs to be changed to meet the functional requirements when the water softener is in normal water production and regeneration. The resin tank assembly is a tank body that holds the regenerated resin. The direction of water flow in the tank body is opposite during regeneration and water production. The flow meter is located at the water inlet end or the water outlet end, and is used to measure the flow of water. According to some embodiments, the water softener may also include an operation display module and a salt box system. The operation display module can be an operation display interface that interacts with people, and users can input parameters and observe the machine operation status through the operation display module. The salt box system can be a barrel assembly that provides regenerated brine to the resin.

[0034] In an embodiment of the present application, an alarm program for abnormal flow of a water softener is run in the control valve assembly. When the accuracy of the flow meter meets the requirements, the flow of the water softener is detected by indicating the flow meter, and the duration of the continuous flow is counted. When the duration of the continuous flow exceeds the preset duration, the abnormal flow alarm mode is started.

[0035] For the alarm scheme of abnormal flow of the water softener running in the control valve assembly, the Figure 2 The illustrated embodiments are described in detail.

[0036] According to one aspect of the present application, a method for alarming abnormal flow of a water softener is provided. Figure 2 FIG. 1 is a flow chart of a method for alarming abnormal flow of a water softener according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0037] Step S201, comparing the error rate of the flow meter of the water softener with a preset value

[0038] Step S202, when the error rate of the flow meter of the water softener is less than a preset value, instructing the flow meter to detect the flow rate; and

[0039] Step S203, counting the time duration for which the flow meter continuously detects flow.

[0040] According to some embodiments, during the use of the water softener, long-term use may cause the attenuation and damage of the flow meter, and the accuracy of the flow meter is likely to become lower and lower. In order to accurately detect the flow of the water softener, the control valve assembly first calculates or obtains the error rate of the water softener flow meter. Among them, the calculation of the error rate of the water softener flow meter will be introduced below. When it is determined that the error rate of the flow meter is less than the preset value, it is considered that the flow meter can still accurately reflect the flow of the water softener. The control valve assembly instructs the flow meter to continuously detect the flow of the water softener. Among them, the preset value can be a value set by a technician based on experience, such as 5%, 20%, etc., and this application does not impose any restrictions on this.

[0041] When the flow meter continuously detects the flow of the water softener, the control valve assembly counts the duration for which the flow meter continuously detects the flow, that is, counts the duration for which the flow meter continuously detects a non-zero value (>0).

[0042] Step S204, when the flow meter continuously detects the flow for a preset time, determining that the water softener has a flow abnormality; and

[0043] Step S205, instructing the alarm device to issue an alarm message.

[0044] According to some embodiments, the preset duration may be a manually set duration, which is usually greater than the duration of flow during normal use of the water softener, for example, 60 minutes, 120 minutes, etc., and the present application does not impose any limitation on this.

[0045] When the flow meter continuously detects flow for a preset time, it can be determined that the water softener has a flow abnormality, for example, there may be abnormal water use or leakage in the pipeline at the rear end of the flow meter. When it is determined that the water softener has a flow abnormality, the alarm device is instructed to issue an alarm message. Among them, the alarm device can be an alarm, such as a buzzer alarm, and the method of issuing an alarm message can include instructing the alarm device to issue an alarm sound; the alarm device can also be an operation display module of the water softener, and the method of issuing an alarm message can include instructing the operation display module of the water softener to display an alarm message; or a combination of the two. Other methods can also be used to issue an alarm message, and this application does not impose any restrictions on this.

[0046] Figure 3 FIG. 1 is a flow chart of a method for alarming abnormal flow of a water softener according to another embodiment of the present application. Figure 2 compared to, Figure 3 Steps S301 to S305 are Figure 2 The steps S201 to S205 are the same as above, except that: Figure 3 The method shown also includes:

[0047] Step S306, in response to the flow meter detecting flow and then not detecting flow, setting the counted time to zero.

[0048] According to some embodiments, when the flow meter detects flow, the control valve assembly counts the duration of the flow meter detecting flow and determines whether the duration reaches a preset duration. If so, an alarm message is issued. If the duration from when the flow meter detects flow to when it does not detect flow does not reach the preset duration, the duration is set to zero. If the duration from when the flow meter detects flow to when it does not detect flow reaches the preset duration, the duration is also set to zero.

[0049] When the flow meter detects flow and then stops detecting flow, the counted time is set to zero. This can prevent the water softener from continuously sounding alarms when a flow abnormality occurs, and can also avoid false alarms caused by continuous statistics of the normal flow of the water softener.

[0050] Figure 4 1 is a flow chart of a method for alarming abnormal flow of a water softener according to another embodiment of the present application. Figure 2 compared to, Figure 4 Steps S401 to S405 are Figure 2The steps S201 to S205 are the same as above, except that: Figure 4 The method shown also includes:

[0051] Step S406, during the process of starting the regeneration process of the water softener, calculating the current error rate of the flow meter.

[0052] According to some embodiments, the flowmeter can be located at the water inlet of the water softener. During the regeneration process of the water softener, the water path of the water softener is: water inlet → flowmeter → control valve assembly → resin tank → control valve assembly → wastewater outlet. Since the control valve assembly has a flow limiting module, and the water softener program has corresponding wastewater flow rates for different water pressures (for example, different water pressures have corresponding wastewater flow rates per unit time), the wastewater flow rate during regeneration can be obtained. Moreover, for the salt absorption from the salt tank, different water pressures also have corresponding flow rates. At the same time, the water softener program can capture the flowmeter flow, compare the captured flowmeter flow Q with the difference between the wastewater flow Q1 and the salt absorption Q2, for example, it can be [Q-(Q1-Q2)] / (Q1-Q2), and the error rate of the flowmeter can be calculated.

[0053] According to some embodiments, step S406 may include:

[0054] When the flow meter is located at the water inlet of the water softener, the current error rate of the flow meter is calculated according to the flow detected by the flow meter, the flow at the wastewater outlet of the water softener and the salt absorption amount corresponding to the salt box.

[0055] According to other embodiments, the flowmeter may also be located at the water outlet of the water softener. According to a specific embodiment, an electrically controlled switch valve may be added between the rear end of the flowmeter at the water outlet of the water softener and the wastewater outlet. The switch valve is closed by default, and when the machine needs to be regenerated, the switch valve is opened. When the water softener needs to be regenerated, the switch valve is opened, and the flow through the flowmeter is the wastewater flow Q. The water softener program has corresponding wastewater flows for different water pressures, so that the wastewater flow Q1 during regeneration can be obtained. The captured flowmeter flow Q is compared with the wastewater flow Q1, for example, it can be (Q-Q1) / Q1, and the error rate of the flowmeter can be calculated.

[0056] According to some embodiments, step S406 may further include:

[0057] In the case where the flow meter is located at the water outlet of the water softener, the current error rate of the flow meter is calculated according to the flow detected by the flow meter and the flow at the wastewater outlet of the water softener.
