Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments according to the invention without any creative effort, are within the protection scope of the invention.
In the industry, in order to solve the problem that water quality is poor when water purifier is reused for the first time after the water purifier is not used for a period of time, zero-ageing water function is preset on the water purifier, namely when the water purifier is not used for a period of time by a user, the water purifier automatically returns pure water, and the polluted pure water at the pure water end is filtered again.
In order to facilitate control, the starting interval time of the zero-water function is a fixed value, but the water quality of different areas is quite different, if the local water quality of a user is better, the zero-water function is not required to be started frequently (the starting frequency of the zero-water function is reduced), otherwise, the waste of water resources and energy sources can be caused, if the local water quality of the user is worse, the starting interval time of the zero-water function is required to be shortened (the starting frequency of the zero-water function is increased), otherwise, the water quality of the first cup of water received by the user when the user uses the water purifying equipment again can not be ensured to meet the requirements, the use experience of the user can be influenced, and even the physical health of the user can be influenced.
Based on the method, the device and the water purifying equipment, the zero-aged water control method and the zero-aged water control device can avoid waste of water resources and energy sources and ensure that the water quality of the discharged water meets the use requirement when the water purifying equipment is reused.
Embodiments of the zero-aged water control method and device and the water purifying equipment of the invention are described below with reference to fig. 1 to 3.
According to an embodiment of the present invention, in a first aspect, there is provided a zero-aged water control method applied to a water purification apparatus, the zero-aged water control method including:
starting for the first time;
acquiring local water quality information;
comparing the information value A of the local water quality with a preset value x and a preset value y;
if x is not less than A and not more than y, the zero-ageing function starting interval time T adopts the standard interval time T 0 ，T＝T 0 ；
If a < x, the zero-staling function starting interval time T is prolonged, T=T 1 ，T 1 ＞T 0 ；
If A > y, shortening the zero-staling function starting interval time T, T=T 2 ，T 2 ＜T 0 。
The zero-water-aging control method adopts an intelligent zero-water-aging scheme, acquires local water quality information during initial starting, compares an information value A of the local water quality with a preset value x and a preset value y, and further determines zero-water-aging function starting interval time according to the actual condition of the local water quality.
The zero-water-supply control method changes the mode of adopting the fixed zero-water-supply function starting interval time in the prior art, can automatically determine the starting time of the zero-water-supply function according to different water quality conditions of areas where different users are located, can avoid water resource and energy waste, can ensure that the water quality of the discharged water meets the use requirement, and can obviously improve the use experience of the users.
The zero-ageing water function is a function of automatically refluxing pure water by the water purifying device when the water purifying device is not used for a period of time and filtering the pure water polluted by the pure water end again so as to avoid the pure water pollution caused by the fact that the water purifying device does not use the pure water end for a long time. The zero-water-ageing control method is used for controlling the starting interval time of the zero-water-ageing function of the water purifying equipment according to the actual water quality condition of the area where the user is located.
Specifically, the zero-old water control method of the embodiment includes:
step S01, starting for the first time;
the primary starting refers to the first power-on starting of the water purifying equipment. After the water purifying equipment is installed, the step of determining the starting interval time of the subsequent zero-staling function is immediately executed when the water purifying equipment is started for the first time, and the water quality of the area where a user is located is almost unchanged.
Step S02, obtaining local water quality information;
after the water purifying equipment is started for the first time, local water quality information is acquired to know whether the actual water quality condition of the area where the user is located is good or poor, and then the starting time of the zero-water-ageing function is determined.
The local water quality information may include various types of TDS values, etc., of the water quality, and the TDS values may be public data values given by a local tap water department (TDS values of a local tap water pipe network) or detection values obtained by detecting the water quality in real time for a water purification apparatus. When the information value A is a detection value, namely the information value A is obtained through a detection means of the water purifying equipment, the information value A can be ensured to be the latest data after the water purifying equipment is started for the first time, and thus the follow-up control accuracy can be improved.
Step S03, comparing the information value A of the local water quality with a preset value x and a preset value y;
if x is not less than A and not more than y, the zero-ageing function starting interval time T adopts the standard interval time T 0 ，T＝T 0 ；
If a < x, the zero-staling function starting interval time T is prolonged, T=T 1 ，T 1 ＞T 0 ；
If A > y, shortening the zero-staling function starting interval time T, T=T 2 ，T 2 ＜T 0 。
In this embodiment, the information value a is a TDS value, the corresponding preset value x and preset value y are two preset TDS thresholds, and the preset value y should be greater than the preset value x.
Through comparison and judgment, if x is not less than A and not more than y, the water quality of the area where the user is located is proved to be moderate, namely the water quality is not good or poor, at the moment, the zero-old water function starting interval time T can adopt a moderate interval time value, namely the zero-old water function starting interval time T adopts a standard interval time T 0 ，T＝T 0 . Standard interval time T 0 Is usually preset in the control system of the water purifying device.
Through comparison and judgment, if A is less than x, the water quality of the area where the user is located is proved to be better, the zero-water-supply function is not required to be started frequently so as to avoid the waste of water resources and energy sources, and the starting interval time T of the zero-water-supply function is required to be prolonged at the moment, wherein T=T 1 ，T 1 ＞T 0 。
Through comparison and judgment, if A is more than y, the water quality of the area where the user is located is proved to be poor, the zero-water-supply function needs to be started frequently to ensure that the water purifying equipment is not used for a period of time, when the water purifying equipment is used again, the water quality of the first cup of water received by the user meets the standard, and at the moment, the starting interval time T of the zero-water-supply function needs to be shortened, and T=T 2 ，T 2 ＜T 0 。
Further, in the step of comparing the information value a of the local water quality with the preset value x and the preset value y, the information value a is a detection value.
In this embodiment, the information value a of the local water quality information is a detection value, that is, detection data obtained by the water purifying apparatus through a detection means. The water purifying equipment detects the obtained information value in real time by the detection means, has higher accuracy, and is favorable for the follow-up accurate judgment and determination of the starting interval time of the zero-stale water function.
In the step of acquiring the local water quality information in this embodiment, the local water quality information is acquired by detecting the TDS value at the water inlet 1 of the water purifying apparatus. The water inlet 1 of the water purifying device is directly connected with a tap water pipe network, the TDS value of the water inlet 1 of the water purifying device can be regarded as the TDS value of the tap water pipe network, and the TDS value of the tap water pipe network can be regarded as the information value A of the local water quality.
Specifically, the TDS test device is used for detecting the TDS value, and the higher the TDS value is, the more the dissolved substances contained in the water are, the worse the water quality is, whereas the lower the TDS value is, the less the dissolved substances contained in the water are, and the better the water quality is. Generally, the total dissolved solids contained in purified water are very small, on the order of zero to several tens of milligrams per liter, and the total solids content increases if the water is contaminated or has dissolved into many other electrolytic substances.
It can be understood that the worse the water quality of the area where the user is located, the faster the pure water end is polluted when the water purifying equipment stops working; on the contrary, the better the water quality of the area where the user is located, the slower the time the pure water end is polluted.
Of course, in other embodiments, in the step of obtaining the local water quality information, the local water quality information may also be obtained through a TDS value of a local tap water network, where the TDS value of the local tap water network is a public data value of a tap water department, so as to simplify the detection and control process.
Further, the range of the preset value x is 170< x <230, and the range of the preset value y is 370< y <430.
In this embodiment, the preset value x is preferably 200, and the preset value y is preferably 400.
Of course, in other embodiments, the preset value x may be set to 171, 193, 220, etc., and likewise, the preset value y may be set to 372, 390, 425, etc.
Further, when x is not less than A and not more than y, the zero-ageing function starting interval time T adopts the standard interval time T 0 ，T＝T 0 Is the step of (a)In step (a), 20 hours<T 0 <And 28 hours.
In the present embodiment, the standard interval time T 0 Preferably 25 hours. When the local water quality of the user is moderate, the zero-old water function of the water purifying device is started every 25 hours, namely the zero-old water function of the water purifying device is started once when the water purifying device stands by for 25 hours.
Of course, in other embodiments, the standard interval time T 0 It can be set to 22 hours, 24 hours, 27 hours, etc.
Further, if a < x, the zero-water function starting interval time T is prolonged, T=T 1 ，T 1 ＞T 0 In the step (2) of 32 hours<T 1 <And 40 hours.
In the present embodiment, T 1 Preferably 36 hours. When the local water quality of the user is good, the starting interval time of the zero-old water function can be prolonged (namely, the starting frequency of the zero-old water function is reduced), and the zero-old water function of the water purifying equipment is started once every 36 hours, namely, the water purifying equipment is standby for 36 hours, and the zero-old water function is started once.
Of course, in other embodiments, T 1 It can be set to 33 hours, 35 hours, 38 hours, etc.
Further, if a > y, shortening the zero-water function starting interval time T, T=T 2 ，T 2 ＜T 0 In the step (2), 8 hours<T 2 <And 16 hours.
In the present embodiment, T 2 Preferably 12 hours. When the local water quality of the user is poor, the starting interval time of the zero-old water function needs to be shortened (namely, the starting frequency of the zero-old water function is improved), and the zero-old water function of the water purifying equipment is started every 12 hours, namely, the water purifying equipment stands by for 12 hours and the zero-old water function is started once.
Of course, in other embodiments, T 2 It can be set to 9 hours, 10 hours, 15 hours, etc.
