Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The embodiment discloses an anti-scaling method for a water purifier and the water purifier for realizing the anti-scaling method, wherein the water purifier can be but is not limited to a table type reverse osmosis water purifier. When the booster pump 1 stops working for more than a set time T, the booster pump 1 is started, raw water 21 (tap water) flows through a first pipeline 31 connected between the raw water tank 2 and the booster pump 1, a second pipeline 32 connected between the booster pump 1 and the filtering system 4, and a third pipeline 33 connected between the filtering system 4 and the raw water tank 2 in sequence, and the raw water 21 flushes the first pipeline 31, the second pipeline 32, and the third pipeline 33 to obtain concentrated water 22 which is injected into the raw water tank 2. Wherein the set time T may be a fixed value, for example, 2h, solidified in the water purifier; or may be a suitable value modified based on other parameters on the basis of the basic value.
The core of the anti-scaling method is that the impact force of water flow is utilized to wash calcium and magnesium ion sediments attached to the original water tank 2, the booster pump 1, the filtering system 4 and the pipeline connected with the structures, so that solid scale capable of blocking the pipeline is prevented from being formed after the calcium and magnesium ions are deposited for a long time. Considering that the solid scale has a greater influence on the structure with a limited cross-sectional area, the first pipeline 31, the second pipeline 32 and the third pipeline 33 are the key positions for removing the calcium and magnesium ion deposits, so that the solid scale is prevented from reducing the diameters of the first pipeline 31, the second pipeline 32 and the third pipeline 33, and the normal flow of water flow is further blocked.
The anti-scaling method uses the raw water 21 in the raw water tank 2 to form water flow for scouring, fully utilizes water resources, does not waste water, has low cost and good anti-scaling effect, and can effectively prolong the service life of the devices such as the booster pump 1, the filtering system 4 and the like.
The specific steps of the anti-scaling method are not limited, and the calcium and magnesium ion sediments in the structure can be washed by utilizing the impact force of water flow. Preferably, the method comprises the following steps:
step S1, monitoring whether the purified water tank 6 is full of water, if yes, going to step S3, otherwise going to step S2. The water purifier also has a primary task of preparing purified water, and the anti-scaling method can be performed only after satisfying the primary task of preparing purified water.
And step S2, when the purified water in the purified water tank 6 is not full, the purified water is required to be prepared continuously, the purified water is injected into the purified water tank 6, and the step S1 is switched after the time reaches a set value.
And step S3, recording the time Tz of the stop of the booster pump 1 when the purified water in the purified water tank 6 is full, starting the booster pump 1 when the time Tz is more than or equal to the set time T, and enabling the raw water 21 to sequentially flow through a first pipeline 31 connected between the raw water tank 2 and the booster pump 1, a second pipeline 32 connected between the booster pump 1 and the filtering system 4 and a third pipeline 33 connected between the filtering system 4 and the raw water tank 2.
In step S4, the time for which the raw water 21 continuously flushes the first, second, and third pipelines 31, 32, and 33 reaches the flush duration H, and then the process ends.
On the basis of the above steps, after step S2 and before step S3, the method further includes:
step S201, detecting a raw water TDS value, and adjusting the value of the set time T and/or the flushing duration H according to the raw water TDS value. Preferably, the higher the TDS value of the raw water, the shorter the set time T and the longer the flushing duration H, the more thorough the descaling is.
In order to avoid influencing the normal use of the water purifier, the control device monitors the on-off condition of the water outlet of the water purifier in real time. When the water outlet of the water purifier is opened, the raw water 21 stops flushing the first pipeline 31, the second pipeline 32 and the third pipeline 33, and the filter system 4 normally prepares the purified water until the purified water tank 6 is filled.
In order to realize the above anti-scaling method, the water purifier includes a booster pump 1, a raw water tank 2, a filtering system 4, a first pipeline 31 connected between the raw water tank 2 and the booster pump 1, a second pipeline 32 connected between the booster pump 1 and the filtering system 4, and a third pipeline 33 connected between the filtering system 4 and the raw water tank 2, forming a circulating water path system.
The filtering system 4 comprises a preposed composite filter element 42, an RO reverse osmosis filter element 41 and an activated carbon rod filter element 43 which are sequentially arranged along the flowing direction of raw water, wherein the RO reverse osmosis filter element 41 comprises a raw water inlet pipe 411 arranged on the side surface of the shell, a purified water outlet pipe 412 arranged on the top of the shell, an RO reverse osmosis pipe 413 and a filter element 414 arranged in the shell, and a waste water outlet pipe 415 arranged at the bottom of the shell, the tubular filter element 414 is sleeved on the outer side of the tubular RO reverse osmosis pipe 413, and the purified water outlet pipe 412 is connected on the RO reverse osmosis pipe 413. The third line 33 is connected between the RO reverse osmosis cartridge 41 and the raw water tank 2.
A raw water TDS detector 71 is arranged at the water inlet of the preposed composite filter element 42 and is used for detecting a raw water TDS value so as to determine proper set time T and proper flushing duration H; a purified water TDS detector 72 is arranged at the water outlet of the RO reverse osmosis filter element 41 and is used for detecting the TDS value of the purified water obtained after the filtration of the RO reverse osmosis filter element 41; the activated carbon rod filter 43 is provided with a water inlet NTC detector 73 (NTC: Negative Temperature Coefficient thermistor in which resistance decreases exponentially with Temperature rise and has a Negative Temperature Coefficient).
The purified water outlet pipe of the filtering system 4 is connected to the purified water tank 6, the purified water tank 6 forms a closed circulation structure with the heating body 8 and the water-vapor separation box 91 through pipelines, and the gas in the water-vapor separation box 91 enters the purified water tank 6 through the exhaust pipe 92.
In order to avoid the normal water production function being affected, a flushing solenoid valve 5 is arranged on the third line 33. When the calcium and magnesium ion sediments need to be flushed by water flow, the flushing electromagnetic valve 5 is opened; and when normal water production is required or the calcium and magnesium ion sediments are washed, closing the washing electromagnetic valve 5.
Preferably, when the water purifier is in a standby state, the detection structure monitors and confirms that the purified water tank 6 is full of water, the booster pump 1 is closed, the flushing solenoid valve 5 is activated (large hole is opened) at the moment when the booster pump 1 is closed, the raw water in the RO reverse osmosis filter element 41 flows into the raw water tank 2 through the large hole of the flushing solenoid valve 5 due to pressure relief, and after 2-3 seconds of continuous activation, the flushing solenoid valve 5 is closed and is maintained in a small hole state.
The water purifier comprises a controller (not shown) arranged on a circuit board of the single chip microcomputer, the single chip microcomputer is electrically connected with the booster pump 1 and can control the start and the stop of the booster pump 1, and the controller detects and records the stop time Tz of the booster pump 1. The controller can be an independent timer with a timing function, or a section of calculation program with the timing function solidified in the singlechip, or other modes or structures capable of realizing the timing function. When the anti-scaling method is executed, when the controller of the water purifier detects that the booster pump 1 does not act for 2-3 hours, the booster pump is started for 1 ten seconds, the flushing electromagnetic valve 5 is activated (opens the large hole) at the moment when the booster pump 1 is started, raw water in the RO reverse osmosis filter element 41 flows into the raw water tank 2 through the large hole of the flushing electromagnetic valve 5 and the third pipeline 33 due to pressure relief, and the booster pump 1 is closed after the raw water is continuously activated for 10 seconds; when the purified water tank 6 stores water, the flushing electromagnetic valve 5 is not activated (small hole is opened), because the diameter of the small hole of the flushing electromagnetic valve 5 is larger than the diameter of the pore of the RO membrane, the concentrated water which does not permeate the RO membrane can flow back to the original water tank 2 through the small hole of the flushing electromagnetic valve 5 and the third pipeline 33. The specific device of the detection structure is not limited, and may be, but not limited to, an infrared sensor or a water level sensor capable of detecting the liquid level height.
In view of the fact that a water purifier (particularly, a desktop reverse osmosis water purifier) is required to be small in size and difficult to be additionally provided for storing concentrated water discharged from the filtration system 4, it is preferable that a raw water outlet and a concentrated water inlet are formed at the bottom of the raw water tank 2, the raw water outlet is connected to the booster pump 1 through a first pipeline 31, and the concentrated water inlet is connected to the filtration system 4 through a third pipeline 33. The raw water outlet is provided with a cylindrical isolation pipe 23 with a certain length towards the inner direction of the raw water tank 2, two ends of the isolation pipe 23 are open, the top of the isolation pipe is opened for allowing the raw water 21 to enter the isolation pipe 23, and the other end of the isolation pipe is connected with the raw water outlet, so that the raw water 21 flows into the first pipeline 31.
The concentrated water flowing into the raw water tank 2 through the third pipeline 33 mainly includes calcium and magnesium ion deposits, which are insoluble in water and heavy, so that a layer is formed in the raw water tank 2, the raw water 21 is positioned above the raw water tank, the concentrated water 22 is positioned at the bottom of the raw water tank, and the isolation pipe 23 has a certain height to ensure that the concentrated water 22 does not flow into the first pipeline 31 from the raw water outlet. When the water level in the raw water tank 2 is lower than the upper end surface of the isolation pipe 23, the control device prompts the user to dump the waste water in the raw water tank 2 and to re-supply raw water to the raw water tank 2.
It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
