[0057] The present disclosure will be further described below by way of examples, but the present disclosure is not limited to the scope of the described examples.

[0058] In the embodiments of the present disclosure, prefix words such as "first" and "second" are only used to distinguish different described objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of ordinal numbers and other prefix words for distinguishing described objects in the embodiments of the present disclosure does not constitute a limitation on the described objects. The statements of the described objects refer to the descriptions in the context of the claims or embodiments, and should not constitute unnecessary limitations due to the use of such prefix words. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "a plurality" is two or more.

[0059] Embodiment 1

[0060] Such as Figure 1As shown in the figure, a water quality detection method for a water purifier is provided in this embodiment. In the water purifier to which this water quality detection method is applied, a heating module 101, a first liquid level detection module 102, and a second liquid level detection module 103 are provided in the water tank. The first detection water level corresponding to the first liquid level detection module is higher than the second detection water level of the second liquid level detection module.

[0061] Among them, the heating module 101 is used to heat the water in the water tank to the temperature required by the user; the first liquid level detection module 102 is used to detect whether the water in the water tank reaches a preset position. For example, the first liquid level detection module is used to detect whether the water tank in the water purifier is full. The specific detection process is that when the liquid level detector in the first liquid level detection module detects a water level signal, it means that the water tank is full; the liquid level signal detected by the liquid level probe in the second liquid level detection module 103 can be combined with the liquid level signal detected by the liquid level probe in the first liquid level detection module to determine whether the water in the water tank meets the water outlet standard, that is, to realize the water quality detection in the water tank.

[0062] As Figure 2 shown in the figure, the water quality detection method in this embodiment includes:

[0063] S21: In response to the water level of the water tank reaching the first detection water level collected by the first liquid level detection module during the first water replenishment and being heated to the preset temperature by the heating module, obtain the first liquid level signal collected by the second liquid level detection module;

[0064] S22: In response to each water replenishment after heating, heat preservation, and evaporation, when the water level in the water tank collected by the first liquid level detection module reaches the first detection water level and the water is heated to the preset temperature by the heating module, obtain the second liquid level signal collected by the second liquid level detection module;

[0065] Among them, the ion concentration in the water tank is negatively correlated with the electric signal intensity detected by the second liquid level detection module; specifically, the heat-preserved and evaporated water is pure water. As the water is continuously heat-preserved, evaporated, and then replenished with water, the total ion amount in the water increases under the condition of the same total water volume, and the ion concentration also increases; and the working characteristic of the module for detecting the water level (such as the probe) is that for the same detection object, the higher the ion concentration, the weaker the detected electric signal; conversely, the lower the ion concentration, the stronger the detected electric signal. Based on this, the detection effect of the water quality change in the water tank is realized.

[0066] S23: Based on the first liquid level signal and the second liquid level signal, determine the water quality situation in the water tank.

[0067] In the water quality detection method of the water purifier provided by the present disclosure, water quality detection is carried out through the liquid level probes originally set in the water purifier, and there is no need to add additional water quality detection sensors. For example, the water in the water purifier when it is first filled and heated is used as the standard liquid level signal, and the liquid level signal detected by the water after being refilled and heated subsequently is used as the real-time liquid level signal. The ion concentration in the water tank is negatively correlated with the intensity of the electrical signal detected by the second liquid level detection module. The ion concentration of the water in the water tank will increase after multiple evaporation and water replenishment. Therefore, by comparing the difference between the standard liquid level signal and the real-time liquid level signal, the change of water quality can be monitored in real time, and without changing the original device of the water purifier, the health problems caused by users drinking or using inferior hot water can be effectively avoided, the user experience and satisfaction are significantly improved, and the cost investment is also reduced.

[0068] In this embodiment, the steps of determining the water quality situation in the water tank based on the first liquid level signal and the second liquid level signal specifically include:

[0069] In response to the difference between the first liquid level signal and the second liquid level signal being greater than or equal to the first threshold, it is determined that the water quality in the water tank does not meet the preset water outlet requirements;

[0070] In response to the difference between the first liquid level signal and the second liquid level signal being less than the first threshold, it is determined that the water quality situation in the water tank meets the preset water outlet requirements.

[0071] In this embodiment, by comparing the difference between the first liquid level signal and the second signal with the set threshold, the water quality result in the water tank can be directly determined, which not only ensures water quality safety and improves user experience, but also greatly reduces the cost of water quality detection.

[0072] The second liquid level detection module in this embodiment includes at least one liquid level probe;

[0073] Among them, when there are at least two liquid level probes, different liquid level probes are set at different water levels in the water tank. Preferably, three liquid level probes are arranged in the water tank from high to low in sequence. The liquid level probe at the highest position can be used to detect whether the water tank is full; the liquid level probe at the middle position can be used to detect whether the injected water reaches the middle position; the liquid level probe at the lowest position can be used to detect whether the water volume in the water tank reaches or is less than the lowest position.

[0074] By arranging multiple liquid level probes at different water levels in the water tank, and then comparing the liquid level signals detected by the multiple liquid level probes under different evaporation conditions with the signal detected for the first time, the setting of the multiple liquid level probes further ensures the accuracy of water quality detection.

[0075] In this embodiment, the steps of determining the water quality situation in the water tank based on the first liquid level signal and the second liquid level signal specifically include:

[0076] Obtain the difference between the first liquid level signal and the second liquid level signal collected by at least one liquid level probe after each water filling and heating is completed.

[0077] In response to any one of the differences being greater than or equal to a preset threshold, it is determined that the water quality in the water purifier does not meet the water outlet requirements.

[0078] In response to any difference being less than the preset threshold, it is determined that the water quality in the water purifier meets the water outlet requirements.

[0079] Among them, different liquid level probes are set with matching preset thresholds.

[0080] In this embodiment, after each water filling and heating is completed, the signal difference is collected by the liquid level probe, which can judge the water quality in the water purifier in real time and accurately, avoid users using unqualified water, and ensure water use safety. By collecting signals through at least one liquid level probe, and different probes having matching preset thresholds, the water quality can be monitored from multiple positions, more comprehensively evaluating the water quality in the water purifier and avoiding misjudgment of the overall water quality caused by local water quality problems.

[0081] After the step of determining that the water quality in the water tank does not meet the preset water outlet requirements, the water quality detection method further includes:

[0082] Drive the drain opening of the water tank to open to drain the water.

[0083] And / or

[0084] Drive the drain opening of the water tank to open to drain the water, and refill the water tank according to the preset user requirements.

[0085] In the water quality detection method of the water purifier provided by the present disclosure, the water quality is detected through the originally provided liquid level probe in the water purifier, and there is no need to add additional water quality detection sensors. For example, the water in the water purifier when it is first filled and heated is used as the standard liquid level signal, and the liquid level signal detected for the water after subsequent refilling and heating is used as the real-time liquid level signal. And the ion concentration in the water tank is negatively correlated with the electric signal intensity detected by the second liquid level detection module. The ion concentration in the water in the water tank will become higher after multiple evaporation and water replenishment. Thus, by comparing the difference between the standard liquid level signal and the real-time liquid level signal, the real-time monitoring of water quality changes is realized. Furthermore, without changing the original device of the water purifier, it effectively avoids health problems caused by users drinking or using inferior hot water, significantly improves the user experience and satisfaction, and also reduces the cost investment.

[0086] Next, combined with examples, the implementation principle of the water quality detection method of the water purifier of the present disclosure will be specifically described:

[0087] As Figure 3 shown, Figure 3It is a schematic diagram of the hot water tank in the water purifier, which has an inlet a, an outlet b, an exhaust port c, as well as a heating element d, a temperature sensor e, and a liquid level probe f.

[0088] The working logic of the heat pipe is as follows: When water does not flow out of the outlet, water enters from the inlet, and the liquid level in the hot water tank gradually rises. When the liquid level touches the lowest liquid level probe, an electrical circuit is formed between the bottom of the lowest liquid level probe and the probe common terminal through water, and at this time, the low liquid level probe generates a signal. However, the middle and high liquid level probes do not come into contact with water, and there is still no signal from these two probes at this time. As the water replenishment continues, the middle liquid level probe will become signalized in turn, and the data will also change with the change of the liquid level. Until the high liquid level also becomes signalized, it indicates that the liquid level has reached the high liquid level, and at this time, the water replenishment stops, indicating that the water tank is full.

[0089] The specific water quality detection method is as follows:

[0090] After the low liquid level touches the water, the low liquid level probe has a jump signal, indicating that the low liquid level has been reached. As the liquid level continues to rise, the signal of the low liquid level also changes and gradually decreases; after the middle liquid level touches the water, the middle liquid level probe also has a jump signal, indicating that the middle liquid level has been reached. As the liquid level continues to rise, the signal of the middle liquid level also changes and gradually decreases; after the high liquid level touches the water, the high liquid level probe also has a jump signal, indicating that the high liquid level has been reached. At this time, it indicates that the water tank is full and the water tank stops taking in water. The signals of each liquid level sensor remain unchanged.

[0091] After the water tank is full, heating starts. The heating element is powered to start heating, and the temperature in the water tank is detected by the temperature sensor. Heating stops after reaching the set temperature. After the water tank stops heating, since the water tank generally has a heat preservation layer for heat preservation, the temperature drop rate of the water tank is relatively slow. Once the temperature drops to the set drop temperature, heating starts again, and the heat preservation cycle is repeated.

[0092] Since the temperature in the water tank affects the conductivity of water, it indirectly affects the water quality detection of the probe.

[0093] After the water tank is filled with water and heated to reach the set temperature value, record the signal data of the low liquid level probe and the high liquid level probe in the water tank as the initial value for subsequent judgment.

[0094] As the water tank is heat-preserved and water vapor evaporates, the liquid level will gradually drop. Once the liquid level is lower than the high liquid level, water replenishment will be carried out, and then heating and heat preservation will be carried out. The evaporated water is distilled water, that is, pure water, while the ions in the water will remain in the water tank. When heated and heat-preserved to the set temperature, due to the increase in ion concentration, the value detected by the liquid level probe will gradually decrease.

[0095] Multiple evaporations and water replenishments will cause the ion concentration in the water tank to continue to increase, that is, the signal detected by the liquid level probe continues to decrease.

[0096] Once the water level reaches the upper level and is heated to the set temperature, when the signal detected by the liquid level probe is lower than the initial value by a certain amount, the water in the water tank starts to be changed. This ratio is generally set to be less than 90% of the initial value.

[0097] After the water tank is completely emptied, it is refilled to the high level. After being heated to the set temperature, the signal data of the probe is detected again and used as the initial value for water quality detection.

[0098] In this embodiment, the signal detection by the liquid level probe is transformed into data analysis to form water quality detection data. By multiplexing the liquid level as a water quality detection sensor, the use effect of the liquid level probe is improved. At the same time, by detecting the change of water quality, the water in the hot water tank can be changed in advance to prevent users from drinking hot water with deteriorated water quality, thereby improving the user experience.

[0099] Embodiment 2

[0100] In this embodiment, a water quality detection system for a water purifier is provided. A heating module, a first liquid level detection module, and a second liquid level detection module are provided in the water tank of the water purifier. The first detection water level corresponding to the first liquid level detection module is higher than the second detection water level of the second liquid level detection module.

[0101] As Figure 4 shown, the water quality detection system in this embodiment includes:

[0102] A first acquisition module 401, configured to, in response to the water level in the water tank reaching the first detection water level collected by the first liquid level detection module during the first water replenishment and being heated to a preset temperature by the heating module, acquire a first liquid level signal collected by the second liquid level detection module;

[0103] A second acquisition module 402, configured to, in response to the water level in the water tank reaching the first detection water level collected by the first liquid level detection module during each water replenishment after heating, heat preservation, and evaporation, and heating the water to the preset temperature by the heating module, acquire a second liquid level signal collected by the second liquid level detection module;

[0104] Wherein, the ion concentration in the water tank is negatively correlated with the electric signal intensity detected by the second liquid level detection module;

[0105] A signal processing module 403, configured to determine the water quality condition in the water tank based on the first liquid level signal and the second liquid level signal.

[0106] The signal processing module 403 in this embodiment is further configured to, in response to the difference between the first liquid level signal and the second liquid level signal being greater than or equal to a first threshold, determine that the water quality in the water tank does not meet the preset water outlet requirement;

[0107] The signal processing module 403 is further configured to determine that the water quality in the water tank meets the preset water outlet requirement in response to the difference between the first liquid level signal and the second liquid level signal being less than the first threshold.

[0108] The second liquid level detection module in this embodiment includes at least one liquid level probe;

[0109] Wherein, when there are at least two liquid level probes, the different liquid level probes are arranged at different water levels in the water tank.

[0110] The signal processing module in this embodiment is further configured to obtain the difference between the first liquid level signal and the second liquid level signal collected by at least one liquid level probe after each water filling and heating is completed;

[0111] In response to any one of the differences being greater than or equal to the preset threshold, it is determined that the water quality in the water purifier does not meet the water outlet requirement;

[0112] In response to any difference being less than the preset threshold, it is determined that the water quality in the water purifier meets the water outlet requirement.

[0113] The preset thresholds of the different liquid level probes provided in this embodiment are matched;

[0114] And / or,

[0115] As Figure 4 As shown, the water quality detection system in this embodiment further includes a drainage module 404, and the drainage module 404 is configured to drive the drainage port of the water tank to open to drain the water after it is determined that the water quality in the water tank does not meet the preset water outlet requirement;

[0116] And / or,

[0117] The drainage module 404 is configured to drive the drainage port of the water tank to open to drain the water, and refill the water tank according to the preset user requirements.

[0118] For the system embodiment, since it basically corresponds to the method embodiment, the relevant parts can refer to the partial description of the method embodiment. The system embodiments described above are only illustrative. The units described as separate components may or may not be physically separated, and the components as units may or may not be physical units, that is, they may be located in one place, or may be distributed to multiple network units. Some or all of the modules can be selected according to actual needs to achieve the purpose of the present disclosure solution.

[0119] In the water quality detection system of the water purifier provided by the present disclosure, the water quality is detected by reusing the liquid level probe originally set in the water purifier, and there is no need to add additional water quality detection sensors. For example, the water in the water purifier when it is first filled and heated is taken as the standard liquid level signal, and the liquid level signal detected from the water after subsequent refilling and heating is taken as the real-time liquid level signal. The ion concentration in the water tank is negatively correlated with the intensity of the electrical signal detected by the second liquid level detection module. The ion concentration in the water in the water tank will increase after multiple evaporation and water replenishment. Therefore, by comparing the difference between the standard liquid level signal and the real-time liquid level signal, the change of water quality can be monitored in real time, and without changing the original device of the water purifier, the health problems caused by users drinking or using poor-quality hot water can be effectively avoided, the user experience and satisfaction can be significantly improved, and the cost investment can also be reduced.

The ion concentration in the water tank is negatively correlated with the intensity of the electrical signal detected by the second liquid level detection module. The ion concentration in the water in the water tank will increase after multiple evaporation and water replenishment. Therefore, by comparing the difference between the standard liquid level signal and the real-time liquid level signal, the change of water quality can be monitored in real time, and without changing the original device of the water purifier, the health problems caused by users drinking or using poor-quality hot water can be effectively avoided, the user experience and satisfaction can be significantly improved, and the cost investment can also be reduced.
