In addition, the warm water stored in the warm water tank (not shown) may be supplied to the user through the intake port.
The filter sterilization system 10 is an apparatus for sterilizing the filter member 100, and the filter sterilization system 10 will be described in detail below.
Referring to the drawings, a filter sterilization system 10 according to an embodiment of the present invention includes: filter member 100, 1 st water channel 200, 2 nd water channel 300, sterilizing substance supply member 400, drain channel 500, and valve 600.
Referring to fig. 1 and 2, the filter member 100 filters raw water 910 supplied from a water supply source. The raw water 910 filtered by the filter member 100 flows out as purified water 920 and is stored in a purified water tank 940.
The filter member 100 may include: a filter part 110, an introduction pipe 120, and a housing 130. The filter part 110 may include various filters so that it can filter the raw water 910.
The introduction pipe 120 is coupled to the filter part 110. For example, referring to fig. 2, the introduction pipe 120 may be coupled to the center portion of the filter part 110, and one or more holes 121 through which raw water 910 or sterilized water 930 may pass are formed in the introduction pipe 120.
Referring to fig. 2, raw water 910 passes through the filter part 110 and moves to the inside of the introduction pipe 120 through the hole 121 formed at the introduction pipe 120, and flows out through the 2 nd waterway 300 connected to the introduction pipe 120 and moves to the fresh water tank 940.
The housing 130 wraps the filter part 110 to protect the filter part 110. That is, the filter part 110 is inserted into the housing 130 to be protected. The 1 st water passage 200 is connected to the case 130, and raw water 910 from a water supply source is filtered by the filter part 110 while moving to the inside of the introduction pipe 120 through the filter part 110 after moving to the inside of the case 130 through the 1 st water passage 200.
Referring to fig. 1, a 1 st water passage 200 is connected to a filter member 100, and raw water 910 flows in the 1 st water passage 200. For example, the 1 st water passage 200 may be connected to the housing 130 of the filter member 100, and the raw water 910 flowing into the 1 st water passage 200 from the water supply source moves toward the housing 130.
Referring to fig. 1, a 2 nd water channel 300 is connected to the filter member 100, and clean water 920 flows out in the 2 nd water channel. For example, referring to fig. 2, the 2 nd water channel 300 may be connected to the introduction pipe 120 of the filter member 100, and the filtered clean water 920 flows out to the clean water tank 940 through the 2 nd water channel 300 while moving toward the introduction pipe 120 through the filter part 110.
That is, referring to fig. 2, the raw water 910 flows into the case 130 from the 1 st water passage 200, moves from the outside of the filter part 110 to the introduction pipe 120 positioned inside the filter part 110, and flows out through the 2 nd water passage 300.
Referring to fig. 1, the sterilizing substance supply member 400 is connected to the 1 st and 2 nd water passages 200 and 300, respectively, and supplies the sterilizing substance 410. For example, the sterilizing substance supply member 400 may be connected to the 1 st water channel 200 through the 3 rd water channel 700 and to the 2 nd water channel 300 through the 4 th water channel 800.
That is, the following configurations are possible: the 3 rd water channel 700 is connected to the 1 st water channel 200 and the sterilizing substance supplying member 400, respectively, and the 4 th water channel 800 is connected to the 2 nd water channel 300 and the sterilizing substance supplying member 400, respectively. In addition, the sterilizing substance supply member 400 may be caused to supply the sterilizing substance 410 through the 4 th water course 800.
Here, the sterilizing substance 410 is mixed to the raw water 910 to generate the sterilized water 930 while the raw water 910 moving through the 3 rd water course from the 1 st water course 200 passes through the sterilizing substance supplying means 400. Then, the sterilizing water 930 in which the raw water 910 and the sterilizing substance 410 are mixed flows into the inside of the filter member 100 to sterilize the inside of the filter member 100.
That is, referring to fig. 1 and 3, the sterilizing water 930 flows into the inside of the introduction pipe 120 through the 4 th and 2 nd water passages 800 and 300, and is discharged to the drainage water passage 500 after sterilizing the inside of the filter part 110 or the inside of the introduction pipe 120. That is, the sterilizing water 930 flows into the inlet pipe 120 from the 2 nd water passage 300, moves from the inside of the filter unit 110 to the outside of the filter unit 110, and is discharged through the drainage water passage 500.
The water drainage channel 500 is connected to the filter member 100 so that it can drain the sterilizing water 930. Referring to fig. 1, the 1 st channel 200 and the 2 nd channel 300 may be located at the same height, and the drainage channel 500 may be located at a lower position than the 1 st channel 200 and the 2 nd channel 300. Thus, referring to fig. 3, the sterilizing water 930 sterilizing the inside of the filter part 110 or the inside of the inlet pipe 120 may be discharged through the drainage passage 500.
On the other hand, after the inside of the filter unit 110 or the inside of the inlet pipe 120 is sterilized by the sterilizing water 930, the raw water 910 flows from the outside of the housing 130 through the filter unit 110 to the inside of the inlet pipe 120, thereby cleaning the filter member 100.
However, the movement of the raw water 910 for cleaning the filter unit 110 and the inlet pipe 120 is the same as the normal raw water 910 of fig. 2, but the raw water 910 for cleaning the filter unit 110 and the inlet pipe 120 is discharged without moving to the clean water tank 940.
Next, the operation and effect of the filter sterilization system 10 according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, when the 1 st valve 610 provided in the 1 st water channel 200 is opened, raw water 910 moves toward the filter member 100. As shown in fig. 2, the raw water 910 moves in the direction of the arrow of the filter member 100.
That is, the raw water 910 flows into the housing 130 connected to the 1 st water passage 200, and is filtered while moving from the outside of the filter unit 110 inserted into the housing 130 to the inlet pipe 120 coupled to the inside of the filter unit 110. The purified water 920 obtained by filtering the raw water 910 flows out along the 2 nd water channel 300 connected to the introduction pipe 120 and moves toward the purified water tank 940.
When it is required to sterilize and clean the filter, the 1 st valve 610 is closed, and at this time, referring to fig. 1, raw water 910 moves from the 1 st water channel 200 to the sterilizing substance supplying member 400 along the 3 rd water channel 700. The sterilizing substance supply means 400 supplies the sterilizing substance 410 to the raw water 910 moving along the 3 rd water course 700, and the raw water 910 and the sterilizing substance 410 are mixed to make the sterilized water 930.
The sterilizing water 930 flows into the inlet pipe 120 of the filter member 100 along the 4 th and 2 nd water passages 800 and 300. Referring to fig. 3, the sterilizing water 930 moves in the direction of the arrow. That is, the sterilizing water 930 flows into the introduction pipe 120 connected to the 2 nd water channel 300, passes through the inside of the filter part 110 from the introduction pipe 120, moves to the outside of the filter part 110, and is then discharged through the drainage water channel 500. Thereby, various microorganisms existing inside the introduction tube 120 can be removed.
As shown in fig. 2, if the sterilizing water 930 moves in the moving direction of the raw water 910, the sterilizing material 410 from which the microorganisms are removed is captured by the filter unit 110 of the filter member 100, and thus there is a problem that the microorganisms in the inlet pipe 120 located inside the filter unit 110 cannot be removed. In order to solve these problems, the filter sterilization system 10 according to an embodiment of the present invention may directly inject the sterilization water 930 into the introduction pipe 120 through the 2 nd water passage 300, thereby having an effect of sterilizing microorganisms of the introduction pipe 120 existing inside the filter part 110.
Further, as shown in fig. 3, since the sterilizing water 930 moves from the inside to the outside of the filter unit 110, that is, in the reverse direction to the filter unit 110, the reverse washing is possible, and the contaminant particles embedded in the layered layer of the filter unit 110 and the contaminant particles remaining on the outer surface of the filter unit 110 can be removed. Thereby, the contaminant particles embedded in the stratification of the filter part 110 and the contaminant particles remaining on the outer side surface of the filter part 110 are removed, and there is also an effect of extending the life of the filter member 100.
Fig. 4(a) and 4(b) are a table and a corresponding graph, respectively, measuring turbidity after reverse washing using the filter sterilization system 10 according to an embodiment of the present invention.
In order to verify the effect of the filter sterilization system 10 according to one embodiment of the present invention, with respect to the filter member 100, after passing any prepared water in a forward direction, washing was performed in a reverse direction to drain the water and turbidity was measured at each time point.
Here, the forward direction indicates a direction in which water moves according to the arrow of fig. 2, and the reverse direction indicates a direction in which water moves according to the arrow of fig. 3.
Referring to fig. 4(a) and 4(b), the turbidity was relatively high at the initial stage before the backwashing, and was 12.2, but it was confirmed that the turbidity decreased with the lapse of time of the backwashing. That is, it can be seen that, when reverse washing is performed in the filter sterilization system 10 according to an embodiment of the present invention, contaminant particles existing in the stratification of the filter part 110 and the outer side surface of the filter part 110 are discharged together with washing water.
Fig. 5(a) and 5(b) are a table and a corresponding graph, respectively, measuring a flow rate after reverse washing using the filter sterilization system 10 according to an embodiment of the present invention.
In order to verify the effect of the filter sterilization system 10 according to one embodiment of the present invention, after the turbidity was adjusted to a level of 20NTU by feeding silicon particles into a 100L water reservoir, the water with poor turbidity was passed through the filter unit 110, and after the 180L water with poor turbidity was passed through, the reverse cleaning was performed.
Referring to fig. 5(a) and 5(b), it can be seen that the flow rate is gradually reduced due to contaminant particles existing in the filter part 110 through which the water having poor turbidity passes. This flow rate is continuously decreased until 180L of the water having poor turbidity passes through the filter unit 110, and the flow rate decrease rate is increased.
Further, it was confirmed that when the backwashing was performed after passing 180L of water having poor turbidity, the flow rate was gradually increased and the flow rate decrease rate was decreased, and after the backwashing, the flow rate was returned to 94.5% of the initial flow rate.
Through such an experiment, it was confirmed that the contaminated substances in the filter unit 110 were cleaned by the backwashing using the filtration and sterilization system 10 according to the embodiment of the present invention.
The invention has been described above with limited embodiments and figures, but the invention is not limited thereto. It is needless to say that various modifications and alterations can be made by those skilled in the art within the scope and range of equivalents of the technical idea of the present invention and the scope of claims described below.
