Description
Technical Field
The invention relates to the technical field of TDS (total dissolved solids) regulation, in particular to a TDS regulation method and system, a storage medium, a control terminal and a water purifier.
Background
Total Dissolved Solids (TDS), also known as Total Dissolved Solids, is measured in milligrams per liter (mg/L) and indicates how many milligrams of Dissolved Solids are Dissolved in 1 liter of water. Higher TDS values indicate more solutes in the water. Total dissolved solids refers to the total amount of total solutes in the water, including both inorganic and organic content. Generally the salt content of the solution is known approximately by the conductivity value available. Generally, the higher the conductivity, the higher the salt content and the higher the TDS. Among inorganic substances, there may be inorganic substances in molecular form in addition to components dissolved in ionic form. Since organic matter and inorganic matter in molecular form contained in natural water are not generally considered, the salt content is generally referred to as total dissolved solids.
In different applications, such as brewing tea and coffee, different requirements are imposed on the quality of water used. For example, coffee brewed with about 150 TDS water can sufficiently dissolve coffee factors and the like in coffee, so that the taste of the coffee is very good. Therefore, water quality with different TDS is required to be provided according to different application occasions.
The water purifier is an appliance which has a function of purifying municipal tap water into direct drinking water and also or simultaneously heats, refrigerates and distributes the purified water by a method of consuming electric energy. Specifically, the water purifier can effectively filter out rust, sand, colloid in water and adsorb chemical agents such as residual chlorine, odor, abnormal color, pesticide and the like in water through a filtering technology, and can effectively remove impurities such as bacteria, germs, toxins, heavy metals and the like in water. The application of water purification technology in the field of drinking water enables the phenomenon of 'water and soil are not uniform' to become history quickly, and the problem that the local diseases are caused by the exceeding of harmful substances in underground water in many places is effectively solved. Meanwhile, the integrated heating function is realized through a heating system taking a metal pipe casting as a core or a heating system taking a quartz glass heating suite as a core.
In the prior art, the water quality generated by the water purifier depends on the state of the adopted filtering system, and the water quality with a specific TDS value cannot be provided, so that the requirements of users cannot be met.

Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The TDS adjusting method and system, the storage medium, the control terminal and the water purifier can flexibly adjust the TDS value of the water outlet of the water purifier, so that different requirements of users are met; learning and memorizing of control parameters of different TDSs are realized through repeated self-learning, so that self-adjustment and intelligent control of the system are realized.
In one embodiment, as shown in fig. 1, the TDS adjusting method of the present invention is applied to a water purifier, which includes an RO water suction pump, an ultrafiltration water suction pump, and an effluent water tank, and the RO water suction pump and/or the ultrafiltration water suction pump provide the effluent water tank with inlet water. The water outlet tank provides purified outlet water for the water purifier.
Specifically, the TDS adjustment method comprises the following steps:
and step S1, acquiring the TDS target value.
Specifically, a user sends a TDS target value of required water to a control terminal on the water purifier through voice, key input, touch screen input or other modes, so that the control terminal acquires the TDS target value.
And step S2, acquiring the TDS value of the water in the effluent water tank.
Specifically, the TDS detection module who sets up in the play water tank gathers the real-time TDS value of play water tank, and send to control terminal.
Step S3, if the TDS value of the water in the effluent water tank is smaller than the TDS target value, the water inlet quantity of the RO water suction pump is reduced, and the water inlet quantity of the ultrafiltration water suction pump is increased; if the TDS value of the water in the water outlet tank is larger than the TDS target value, the water inlet quantity of the RO water suction pump is increased, and the water inlet quantity of the ultrafiltration water suction pump is decreased; and if the TDS value of the water in the effluent water tank is equal to the TDS target value, keeping the water inflow of the RO water suction pump and the ultrafiltration water suction pump and storing the water inflow setting parameters of the RO water suction pump and the ultrafiltration water suction pump.
Ultrafiltration is one of the membrane separation techniques using pressure as the driving force. The pore diameter of the membrane is between 20 and 1000A DEG for the purpose of separating macromolecules from small molecules. Therefore, the ultrafiltration system realizes the filtration of the quality of tap water or an external water source, and hardly changes the TDS value of the water source. RO is an abbreviation for Reverse Osmosis, meaning Reverse Osmosis. The pore diameter of the RO reverse osmosis membrane is as small as a nanometer (10 × 9 m) and water molecules can pass through the RO membrane under a certain pressure, while impurities such as inorganic salts, heavy metal ions, organic matters, colloids, bacteria and viruses in source water cannot pass through the RO membrane, thereby strictly separating permeable pure water from impermeable concentrated water. Thus, the output TDS of an RO filtration system is typically very small because it employs reverse osmosis filtration.
Due to the characteristics of the ultrafiltration system and the RO filtration system, the control terminal needs to control the water inflow of the RO water suction pump and the ultrafiltration water suction pump, so as to control the effluent water tank to provide effluent with a specific TDS value.
Specifically, the TDS value of the water in the outlet tank is first compared to the TDS target value. If the TDS value of the water in the effluent water tank is larger than the TDS target value, the water inflow of an RO water suction pump needs to be increased, and the water inflow of an ultrafiltration water suction pump needs to be reduced, so that the water inflow of the RO water suction pump is increased, and the water inflow of the ultrafiltration water suction pump is decreased; if the TDS value of the water in the effluent water tank is smaller than the TDS target value, the water inflow of an ultrafiltration water suction pump needs to be increased, and the water inflow of an RO water suction pump needs to be reduced, so that the water inflow of the ultrafiltration water suction pump is increased, and the water inflow of the RO water suction pump is decreased; if the TDS value of the water in the water outlet tank is equal to the TDS target value, the TDS value indicates that the current TDS value of the water outlet tank is the TDS target value, the adjustment is finished, and only the RO water suction pump and the water inflow of the ultrafiltration water suction pump need to be kept, and the RO water suction pump and the water inflow of the ultrafiltration water suction pump are stored simultaneously to set parameters, so that the control terminal has a memory function, self-learning and self-control of the water purifier are realized, and the water purifier is more intelligent, reliable and safe.
In an embodiment of the present invention, the maximum value of the TDS target value is the TDS value of the water in the effluent water tank when the RO water suction pump is turned off and the ultrafiltration water suction pump is turned on; the minimum value of the TDS target value is the TDS value of the water in the effluent water tank when the RO water suction pump is turned on and the ultrafiltration water suction pump is turned off. Therefore, the TDS value of the effluent water tank reaches a preset value by adjusting the water inflow of the RO water suction pump and the ultrafiltration water suction pump.
In one embodiment, as shown in fig. 2, the TDS regulation system of the present invention is applied to a water purifier comprising an RO water suction pump, an ultrafiltration water suction pump, and an effluent tank.
The TDS conditioning system includes a first acquisition module 21, a second acquisition module 22, and a conditioning module 23.
The first acquiring module 21 is configured to acquire a TDS target value.
Specifically, a user sends a TDS target value of required water to a control terminal on the water purifier through voice, key input, touch screen input or other modes, so that the control terminal acquires the TDS target value.
The second acquiring module 22 is configured to acquire a TDS value of the water in the outlet tank.
Specifically, the TDS detection module who sets up in the play water tank gathers the real-time TDS value of play water tank, and send to control terminal.
The adjusting module 23 is connected to the first acquiring module 21 and the second acquiring module 22, and is configured to reduce the water inflow of the RO water suction pump and increase the water inflow of the ultrafiltration water suction pump if the TDS value of the water in the effluent water tank is smaller than the TDS target value; if the TDS value of the water in the water outlet tank is larger than the TDS target value, the water inlet quantity of the RO water suction pump is increased, and the water inlet quantity of the ultrafiltration water suction pump is decreased; and if the TDS value of the water in the effluent water tank is equal to the TDS target value, keeping the water inflow of the RO water suction pump and the ultrafiltration water suction pump and storing the water inflow setting parameters of the RO water suction pump and the ultrafiltration water suction pump.
Ultrafiltration is one of the membrane separation techniques using pressure as the driving force. The pore diameter of the membrane is between 20 and 1000A DEG for the purpose of separating macromolecules from small molecules. Therefore, the ultrafiltration system realizes the filtration of the quality of tap water or an external water source, and hardly changes the TDS value of the water source. RO is an abbreviation for Reverse Osmosis, meaning Reverse Osmosis.

Thus, the output TDS of an RO filtration system is typically very small because it employs reverse osmosis filtration.
Due to the characteristics of the ultrafiltration system and the RO filtration system, the control terminal needs to control the water inflow of the RO water suction pump and the ultrafiltration water suction pump, so as to control the effluent water tank to provide effluent with a specific TDS value.

In an embodiment of the present invention, the maximum value of the TDS target value is the TDS value of the water in the effluent water tank when the RO water suction pump is turned off and the ultrafiltration water suction pump is turned on; the minimum value of the TDS target value is the TDS value of the water in the effluent water tank when the RO water suction pump is turned on and the ultrafiltration water suction pump is turned off. Therefore, the TDS value of the effluent water tank reaches a preset value by adjusting the water inflow of the RO water suction pump and the ultrafiltration water suction pump.
