Alternatively, the pipe may be formed to be branched so that the pipe is piped through a single pipe connector so that the pipe can be separately flowed from the wash water and the filtered water.

Three stopping chambers 122a, 122b and 122c were applied.

The stopping chambers 122a, 122b and 122c have a structure in which the top and bottom thereof are open and have a joining flange portion extending further outward from the sidewall to form a joining hole.

Filtration yarn 131 is filled in the stopping chambers 122a, 122b and 122c, and the filtered yarn 131 is suppressed to prevent the filtered yarn 131 from flowing out of the stopping chambers 122a, 122b and 122c. A filtration filter 133 having a smaller hole than the filtration yarn 131 is provided outside the filtration yarn layer filled with 131.

The filtration filter 133 may be further applied between each of the stopping chambers 122a, 122b, and 122c, and the filter medium filled in each of the stopping chambers 122a, 122b, and 122c may be in the direction of the filtered water supply path. Depending on the size of the progressively small, it can be applied in a multi-layer in the form of royal sand, heavy sand, fine sand, or other kinds of filter media, for example, can be applied a variety of known filter media such as activated carbon.

Various known structures may be applied to the filtration filter 133, and as an example, a plate shape formed in the form of a film in which copper and aluminum powder are impregnated into the water-permeable foam molded article may be applied.

The chambers 121, 122a, 122b, 122c, and 123 of such a structure are mutually assembled and used by assembling a plurality of arrays using bolts 135 and nuts 136 vertically applied as coupling members. It provides the advantage that can be separated from each other when the filter medium replacement and replenishment.

In addition, in the illustrated example, each chamber 121, 122a, 122b, 122c of the filtration chamber unit 120 has a rectangular structure, but may be formed in various shapes such as a circular structure.

Unlike the illustrated example, the filtration chamber unit 120 may be integrally formed.

The chambers 121, 122a, 122b, 122c, and 123 are preferably formed of a transparent material, for example, a transparent acrylic plate material, to enable internal perspective so that contamination can be checked from the outside.

The control system of each element of such a filtration device will be described with reference to FIG.

The pressure detection sensor 140 outputs the detected pressure signal to the controller 160.

The water level detection sensor 210 detects the water level of the reservoir 200 and outputs it to the controller 160. The water level detection sensor 210 may be omitted.

The valve controller 161 controls the opening and closing of the first to fourth valves 114 to 117 according to the control signal of the controller 160.

The pump controller 163 is controlled by the controller 160 to control the driving of the first pump 111 and the second pump 113.

The control unit 160 selectively controls the valves 114 to 117 according to the output signal of the pressure detection sensor 140 to form a flow path through the filtered water discharge path leading from the intake pipe 101 to the reservoir 200 to supply the raw water. A filtration mode for filtration and a washing mode for washing are selectively performed to allow the washing water to flow through the washing water discharge path.

Preferably, when the pressure value detected by the pressure detection sensor 140 is higher than the set first reference pressure value, the controller 160 closes the filtered water discharge path and opens the washing water discharge path to perform the cleaning mode. 117) and the pumps 111 and 113, and when the second reference pressure value lower than the first reference pressure value is reached after performing the washing mode, the washing water discharge path is blocked and the filtered water discharge path is opened to filter the raw water. To control the valves 114 to 117 and the pumps 111 and 113 to be supplied to the reservoir.

 A process of controlling the valve and the pump of the controller 160 will be described with reference to FIG. 5.

The water pressure Pf is detected at the set position on the flow path from the water intake pipe 101 to the inside of the filtration chamber unit 120 (step 310). Preferably, as described above, the pressure of the front chamber 121 is detected.

Next, it is determined whether the detected water pressure Pf is greater than the set first reference value Pref1 (step 320).

If it is determined in step 320 that the water pressure is greater than the set first reference value, it is determined that the filtration capacity of the filter medium due to the deposition of foreign matters is reduced and a washing mode for washing the filter medium is performed (step 330).

In the washing mode, the first valve 114 and the second valve 115 are controlled to be closed, and only the second pump 111 is driven while the third valve 116 and the fourth valve 117 are opened. To perform. Fresh water stored in the reservoir 200 by performing the washing mode is discharged to the outside through the washing water discharge pipe 105 through the filtration chamber unit 120 and in the process to the filter yarn 131 and the filtration filter 133 Adhered sludge and debris are removed.

Then, it is determined whether the washing mode end condition is reached (step 340).

The wash mode end condition may be set to a time or pressure value. When the washing mode is set to be performed for a set time, for example, 10 minutes, the time is counted to determine whether the set time is reached. In this case, when the washing mode execution time reaches the set time in step 340, the washing mode ends (step 350).

 Preferably, the washing mode end condition is set to determine that the washing mode end condition is reached when the water pressure reaches the second reference value set lower than the set first reference value.

In this case, when the water pressure detected by the pressure detection sensor 140 reaches the second reference value Prdf2 set lower than the first reference value in step 340, the washing mode ends.

On the other hand, if it is determined that the water pressure detected in step 320 is lower than the set first reference value, the filtration mode is performed (step 360).

In the filtration mode, the first pump 114 and the second valve 115 are controlled to be opened, and the third pump 111 is properly closed while the third valve 116 and the fourth valve 117 are closed. Run by it.

It is preferable that the driving of the second pump 111 in the filtration mode is selectively performed by the controller 160 according to the signal of the water level detection sensor 210 installed in the reservoir 200.

On the other hand, unlike the example described above, it is possible to install the pipe and the valve so as to generate the flow rate while selectively forming the filtered water discharge path and the wash water discharge path by using a single pump, as well as an example 6 is shown. Elements having the same function as in the above-described drawings are denoted by the same reference numerals.

Referring to FIG. 6, fresh water stored in the reservoir 200 is piped to be supplied as the washing water to the end chamber via the first pump 111.

The washing water inflow pipe branches from the fresh water discharge pipe of the reservoir 200 and is branched from the first wash water inflow pipe 104a and the raw water inflow pipe 102 connected to the intake pipe 101 to the termination chamber. It is formed by the wash water inflow pipe 104b.

Reference numerals 411 and 412 denote valves that are additionally installed to selectively supply raw water and fresh water of the reservoir to the first pump 111.

Unlike the illustrated example, it is a matter of course that the three-way valve may be applied to the branch point of the pipe.

In addition, the filtration chamber unit 120 may be piped so that the flow path is formed from the bottom to the top in the filtration mode, the flow path is formed from the top to the bottom in the washing mode.
