The invention provides a water purifying device which can carry out secondary purification on primary purified water flowing out of a pressure water reservoir, thereby eliminating secondary pollution of the primary purified water in the pressure water reservoir or a pipeline.
In one embodiment of the present invention, as shown in fig. 1 and 2, the water purifying apparatus includes: the water supply assembly 100, the first water purification assembly 200, the pressure reservoir 300, the second water purification assembly 400, the water outlet assembly 500, the heating device 600, and the control assembly 700. Wherein the first water purifying assembly 200 is connected to the water supplying assembly 100 to treat raw water flowing out of the water supplying assembly 100; the pressurized water reservoir 300 is connected to the first water purification module 200 to store purified water; the second water purifying assembly 400 is connected to the pressure water reservoir 300 to purify water flowing out of the pressure water reservoir 300; the water outlet assembly 500 is connected to the second water purifying assembly 400 to flow out purified water, and a pressure balance valve 530 is provided on the water outlet assembly 500 to return residual liquid in a water outlet pipeline between the water outlet assembly 500 and the second water purifying assembly 400 to the second water purifying assembly 400; the heating device 600 is used for heating the purified water; the control assembly 700 is electrically connected to the first water purifying assembly 200 and the second water purifying assembly 400 to turn on the first water purifying assembly 200 in a water storage mode and to turn on the second water purifying assembly 400 in a water discharge mode.
The operation mode of the water purification apparatus includes two modes, namely a water storage mode in which the control assembly 700 opens the first water purification assembly 200 to continuously purify raw water flowing out of the water supply assembly 100 and then flow the purified water into the pressure water reservoir 300, and in addition, the control assembly 700 continuously detects the pressure in the pressure water reservoir 300, the pressure value is proportional to the volume of purified water in the pressure water reservoir 300, and when the pressure value reaches a preset value, the purified water in the pressure water reservoir 300 reaches the preset value, and at this time, the controller turns off the first water purification assembly 200 to no longer generate purified water; in the water outlet mode, the control assembly 700 opens the second water purifying assembly 400, and the purified water in the pressure water reservoir 300 flows to the water outlet assembly 500 after being purified by the second water purifying assembly 400, so as to be drunk by a user, and in addition, the patent is further provided with the heating device 600, and the heating device 600 can heat the purified water which is secondarily purified, so that the secondary purified water is purified at a high temperature and hot drinking water is provided for the user.
The water purification equipment in this patent can carry out secondary purification through the one-level purified water that second water purification subassembly 400 was flowed out to the pressure water receiver 300 to eliminate one-level purified water and store bacterium and the microorganism that the in-process breeded in the pressure water receiver 300, and then realize the secondary purification of one-level purified water, produce purer, the better secondary purified water of taste.
Secondly, the water purifying device provided by the patent can acquire the pressure value in the pressure water reservoir 300 in real time through the control component 700, and control the opening or closing of the first water purifying component 200 through monitoring the pressure value, so that the pressure water reservoir 300 is guaranteed to always have a proper amount of primary purified water. Specifically, when the pressure value in the pressure reservoir 300 is small, i.e., the amount of primary purified water in the pressure reservoir 300 does not reach a preset value, the control unit 700 controls the first water purifying unit 200 to be turned on, and the first water purifying unit 200 continuously generates primary purified water and delivers the primary purified water to the pressure reservoir 300; when the pressure value in the pressure reservoir 300 is large until the preset value of the control assembly 700 is exceeded, the control assembly 700 turns off the first water purifying assembly 200, thereby avoiding an excessive amount of primary purified water in the pressure reservoir 300. The preset pressure value is set according to the water consumption of the user, specifically, when the water consumption of the user is high in daytime, the preset pressure value can be set relatively high, so that the purified water in the pressure water reservoir 300 is guaranteed to be supplied enough, when the water consumption of the user is low in night, the preset pressure value can be set relatively low, the condition that the amount of the primary purified water stored in the pressure water reservoir 300 is too high is avoided, the secondary pollution amount of the primary purified water is reduced, and the purified water cost of the water purifying device is reduced.
Again, the water purification apparatus of this patent can provide purified water fast. Specifically, since the water purifying apparatus of the present patent has the pressure water reservoir 300 and the pressure water reservoir 300 stores the proper amount of the first purified water, when the user opens the water outlet assembly 500, the first purified water in the water reservoir pressure rapidly flows into the second water purifying assembly 400 and is purified by the second water purifying assembly 400 to be drunk by the user. Since the first water purifying unit 200 generally has a long water purifying time, and the water purifying apparatus according to the present patent has completed the primary purification of raw water when receiving the water outlet signal, the water purifying apparatus according to the present patent can rapidly generate purified water for drinking by a user.
Finally, the water purification equipment of the patent can purify residual liquid in the water outlet pipeline and provide purified water with higher purity. Because this patent water purification unit is equipped with pressure balance valve 530 on water outlet assembly 500, this pressure balance valve 530 is at the back of opening water outlet assembly 500 at first with the residual liquid backward flow in the water outlet pipeline to second water purification assembly 400, just flow second grade purified water after water outlet assembly 500 is discharged residual liquid, therefore, the water purification unit that this patent provided can avoid residual liquid in the water outlet pipeline to lead to the problem that purified water is not fresh to provide clean, fresh purified water for the user.
In the above embodiment of the present patent, the control assembly 700 includes: a pressure sensor and a controller, wherein the pressure sensor is configured to obtain a pressure value within the pressure reservoir 300; when the pressure value is smaller than a preset value, the controller obtains a water storage signal, so that the controller starts the first water purifying component 200, the first water purifying component 200 conveys purified water to the pressure water storage device 300, and the water purifying device is in a water storage mode; when the controller obtains a water outlet signal, the controller starts the second water purifying assembly 400, water in the pressure water reservoir 300 is conveyed to the water outlet assembly 500 through the second water purifying assembly 400, and the water purifying device is in a water outlet mode.
In order to accurately determine the working time of the pressure balance valve 530, so as to ensure that the residual liquid in the water outlet pipeline between the water outlet assembly 500 and the second water purifying assembly 400 is drained, and avoid excessively long backflow time and influence on timely drinking of clean purified water by a user, in an embodiment of the present invention, the control assembly 700 further includes a first timing module electrically connected with the pressure balance valve 530 to record the working time of the pressure balance valve 530, and when the working time is greater than or equal to a preset time length, the controller closes the pressure balance valve 530 and opens the water outlet assembly. In this embodiment, the preset time length is calculated according to the length of the pipeline and the flow rate of the liquid, but the design of the present patent is not limited thereto, and in other embodiments, the preset time length may also be directly input by the user.
Describing the principle of the first timing module for calculating the preset duration in detail, the hydraulic gradient of the pipeline can be calculated by using a Sevelev formula to calculate i=0.00107V 2/d 1.3, and i= (P1-P2)/(ρgL); the two formulas can be obtained after i is eliminated: v=30.57 d 0.65{ (P1-P2)/ρgL }. 0.5 this suggests that the flow velocity V in a pipe is proportional to the square root of the pressure difference P1-P2 per unit length in the pipe, proportional to the 0.65 th root of the pipe inner diameter d, and inversely proportional to the 0.5 th root of the pipe length L.
Wherein P1: pipe head pressure; p2: pipe end pressure; ρ: the density of the water; l: the length of the pipeline; i: hydraulic gradient; v: a flow rate; d: the inner diameter of the pipeline.
Therefore, after measuring the length L of the pipe and the inner diameter d of the pipe, the pressure sensor can measure the pressure difference P1-P2 of the unit length in the pipe, and the processor can calculate the flow velocity V of the liquid in the pipe according to the formula; at this time, the first timing module can calculate the preset duration required by the residual liquid flow according to the length L of the pipeline and the liquid flow velocity V.
However, the design of the present patent is not limited thereto, and in other embodiments, the control assembly 700 may further include a water flow rate hall sensor and a processor, so that the control assembly 700 may directly detect the liquid flow rate in the water pipeline through the water flow rate hall sensor, and further calculate the preset duration required for purifying the residual liquid flow according to the liquid flow rate and the pipeline length through the first timing module.
In the above embodiment of the present invention, in order to further accelerate the time for obtaining fresh purified water for the user, the control assembly 700 of the water purifier further includes a second timing module, where the second timing module obtains an average time interval between two adjacent uses of the water outlet assembly 500 in a preset time period, so that the control assembly 700 opens the pressure balance valve 530 when the time interval of use of the water outlet assembly 500 is greater than or equal to the average time interval, so as to reflux the residual liquid in the water outlet pipeline to the second water purification assembly 400 through the pressure balance valve 530.
That is, the water purifying apparatus in this embodiment can return the residual liquid in the water outlet pipeline to the second water purifying component 400 in the water outlet mode, and can also have a water purifying function in the water storage mode, so that when the water purifier is switched from the water storage mode to the water purifying mode, fresh purified water can be obtained quickly. Specifically, the second timing module can monitor the condition of using the water purifying equipment by a user in real time, so that the requirements of the user for fresh purified water in different time periods are recorded. For example, the user uses the water purifying device once every 0.5 hour on average in a high-frequency use period, and uses the water purifying device once every 4 hours on average in a high-frequency use period; the second timer module calculates the average usage time interval of the user to be 2 hours through the data recorded in the long term, and then the second timer module automatically triggers the control module 700 to open the pressure balance valve 530 during the low frequency usage time period such as the night or the early morning, so that when the user uses water, the residual liquid in the pipeline is purified and can be drunk directly, and therefore the user can drink pure and fresh purified water quickly in the early morning.
As a preferred way, the present invention adopts different average time intervals in the high frequency use period and the low frequency use period as a criterion of whether to perform automatic water return in order to save the cost of water purification. In particular, in a high frequency usage period, for example, 6:00 a.m. to 22:00 a.m., the second timing module may subtract the adjustment amount of 1 hour on an average time interval of 2 hours as a control criterion for the high frequency usage period; whereas in a low frequency usage period, e.g. 22:00 late to 6:00 early the next day, the second timing module may add an adjustment amount of 1 hour on the basis of an average time interval of 2 hours as a control criterion for the high frequency usage period, i.e.: different control standards are adopted in the high-frequency use period and the low-frequency use period, so that the execution frequency of the water return function is higher in the high-frequency use period, and the time for a user to drink purified water is shorter; in the low frequency use period, the fresh water function is performed at a lower frequency, so that the electric quantity can be saved, the high frequency operation of the pressure balance valve 530 is avoided, and the service life of the pressure balance valve 530 is prolonged.
However, the design of the present patent is not limited thereto, and in other embodiments, automatic water return may be performed only on some time nodes of high-frequency drinking water, for example: the automatic water return is carried out once in the morning of 6:00, so that the requirement of a user for drinking purified water in the early morning can be met, and the electric quantity can be saved.
With continued reference to fig. 2, in an embodiment of the present disclosure, the first water purifying component 200 includes a pre-composite filter element 210 and a reverse osmosis filter element 220 connected in sequence; the second water purification assembly 400 includes a post-positioned composite filter element 410.
