Description

Natural filtering water purifier with improved filtering system {NATURAL FILTERING PURIFIER WITH IMPROVED FILTERING SYSTEM}

The present invention relates to a natural filtration type water purifier to which an improved filtering system is applied, and more particularly, to prevent a phenomenon in which raw water does not pass smoothly due to a water film phenomenon due to a pressure difference between multi-layered filter layers, thereby improving the flowability of raw water. It is possible to increase the filter use efficiency by further improving the filter and allowing the raw water to pass through the entire area of the filter, and to ensure the convenience of maintenance by making the replacement of the filter easier. It is about a filtering water purifier.

In general, a water purifier is a device for purifying raw water such as tap water or mineral water, and provides drinking water beneficial to the human body by removing heavy metals or other harmful substances contained in raw water based on a water purification method including processes such as precipitation, filtration, and sterilization. do.

These water purifiers can be largely classified into a water tank type (natural filtration type) and a reverse osmosis type according to the operation method.

Reverse osmosis water purifier applies pressure to the water outside the filter and passes it through a dense filter to filter out heavy metals, viruses, and microorganisms to remove purified water and contaminants. Various electrical devices that can pump water and drive it It is a method mainly used in general homes or restaurants because it requires constant power for

On the other hand, natural filter water purifiers pass raw water stored in a water tank through a filter by natural principles such as gravity, store the purified water in a water purification tank, and then consume water as needed. Since it does not require a simple structure and does not require constant power, it is easy to move and install, so it is mainly used and installed outdoors or in public places.

Most of these natural filtration type water purifiers purify raw water using a multi-stage filter module in which functional filter layers are stacked in multiple stages. filter use efficiency was reduced.

In addition, when the raw water flows in one direction on the surface of the dried filter layer, a so-called water path is created, and the raw water flows only in a specific part of the filter layer due to the nature of the raw water flowing only through the water path, so that the entire area of the filter layer is efficiently used. There was a problem.

In addition, when a water film is formed on the outer surface of the filter layer due to a pressure difference in the space between each filter layer or the viscosity of the surface of the filter layer, raw water is blocked by the water film and cannot pass through the filter layer, thereby reducing the efficiency of producing purified water. .

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation. It should be noted that in each drawing, the same members are sometimes indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

A natural filtering type water purifier (hereinafter referred to as a water purifier) to which an improved filtering system according to the present invention is applied is largely located in a water storage tank 10 in which raw water is stored and a lower portion of the water storage tank 10, as shown in FIGS. 1 to 5 It may be defined as including a combined water purification tank 20 and a filtration module 30 built in the water purification tank 20 and purifying raw water supplied from the water storage tank 10.

The raw water filled in the water storage tank 10 may pass through the filtration module 30 and be stored in the purified water tank 20 in a purified state. Although not shown, the purified water tank 20 includes the purified water tank 20 ), a dispenser may be installed to discharge purified drinking water to the outside by a fixed amount.

The inner space of the water storage tank 10 and the water purification tank 20 is divided into two, and has a structure so that raw water filled in the water storage tank 10 can be supplied to the water purification tank 20 only through the filtration module 30.

For example, a water reservoir 11 having a predetermined diameter for passing raw water may be formed through the bottom surface of the water storage tank 10, and at the same time, the upper part of the water tank 20 is open and the lower part of the water tank 10 is formed. The filtration module 30 is placed directly below the water inlet 11 while being supported on the filter support 40 installed between the water storage tank 10 and the water purification tank 20 to purify raw water. can

Accordingly, the raw water filled in the water tank 10 may freely fall downward toward the filtration module 30 and then be purified by the filtration module 30 and stored in the purifying tank 20 as drinkable drinking water.

The filtration module 30 has a structure capable of more efficiently collecting harmful substances by purifying the raw water freely falling from the water tank 10 step by step.

For example, the filtration module 30 is made of a cylindrical shape with an open top, a housing 31 having a first discharge port 31a formed on the lower surface, and a plurality of multi-stage installations spaced apart at regular intervals vertically inside the housing 31. It may be exemplified as including a filter 33 mounted in a space between one diaphragm 32 and an adjacent diaphragm 32 .

Support protrusions (not shown) are formed on the inner wall of the housing 31 to support each filter 33 at a predetermined height so that the filter 33 can be supported at a predetermined height.

And, when the diaphragm 32 is mounted, the diaphragm 32 is always guided in the same direction, and a guide bar 31b is provided on the inner wall of the housing 31 in the vertical direction so that the diaphragm 32 does not rotate in place. may protrude. A plurality of guide stands 31b may be arranged at equal angles.

Complementarily to this, a guide groove 32d connected to the guide base 31b may be recessed around each of the plurality of diaphragms 32 .

When a plurality of diaphragms 32 are mounted in multiple stages into the housing 31, a filter loading room may be provided between adjacent diaphragms 32, and each filter 33 may be inserted and installed on the filter loading room. there is.

The filter 33 may use a known means in line to purify the raw water to be drinkable. For example, the filter 33 may adsorb and remove organic compounds such as residual chlorine contained in water and various odors. , zeolite to remove ionic substances, elvan silica sand or silica cornice to improve water taste and maintain cleanliness, and silver particles having a certain diameter to remove odors to act as general bacteria and antibacterial.

Each diaphragm 32 supports the filter 33 from the lower portion, but a passage hole 32a through which raw water passes may be formed through. Accordingly, a structure is provided in which raw water can pass through both the diaphragm 32 and the filter 33 without difficulty, and furthermore, the drinking water that has passed all the filters 33 passes through the first outlet 31a of the housing 31. Through this, it can be discharged to the purified water tank 20.

On the other hand, each filter loading room has a relatively closed structure formed by the filter 33 and the diaphragm 32, and due to the structure in which raw water flows in, the inside is not easily ventilated, and a pressure difference may occur in each filter loading room. can

In the case of the reverse osmosis water purifier described above, raw water is pumped with strong pressure, so even if a water film phenomenon occurs on the filter 33 or the diaphragm 32, the raw water can be easily discharged by destroying it, but the natural filtration water purifier In this case, since the raw water is supplied only by its own weight, the supply pressure of the raw water is relatively lowered, so when a water film is generated, the raw water does not easily pass through it, and the flow path is clogged.

In this embodiment, in order to solve this pressure difference, a pressure holding protrusion 32b is protruded upward from the upper surface eccentrically spaced from the center to one side of the diaphragm 32, and a vent is formed on the pressure holding protrusion 32b in a vertical direction ( 32c) has a structure through which it is formed.

That is, since the pressure holding protrusion 32b protrudes at a certain height, the raw water flowing into the filter loading chamber cannot easily rise up to the upper end of the pressure holding protrusion 32b and is difficult to flow into the vent 32c. becomes Accordingly, only air passes through the ventilation hole 32c so that air can circulate in each filter loading chamber, effectively eliminating the pressure difference. Accordingly, the raw water flow path is not blocked and the raw water can be smoothly discharged.

The number of filters 33 and diaphragms 32 is not particularly limited as long as they form a structure in which they are alternately disposed inside the housing 31 .

On the other hand, the filtration module 30 may further include a diffusion plate 34 mounted on the open top of the housing 31 to diffuse and fall the raw water.

A distribution hole 34a may be radially formed in the diffusion plate 34 so as to widely distribute the raw water.

Thus, the raw water can be diffused and contacted to the filter 33 over a wider area.

Meanwhile, an auxiliary filter 60 that purifies raw water once more may be disposed at the lower portion of the housing 31 in consideration of harmful substance removal efficiency, and a ceramic filter 50 may be mounted at the water reservoir 11.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. 6 . In this embodiment, detailed descriptions of parts identical or similar to those of the previous embodiment are omitted to avoid duplication. There are differences, and we will focus only on these differences.

On the other hand, in order to replace the filter 33 in a typical natural filtration type water purifier, at least all of the raw water in the water storage tank 10 must be drained before the replacement work is performed.

Since the housing 31 itself supporting the filter 33 is immersed as it is in the raw water of the water tank 10 or the drinking water of the purified water tank 20, the filter ( When performing the replacement work in 33), the operator's hands and other tools are exposed to the raw water, which does not guarantee workability as well as contamination of the raw water.

Therefore, in the present embodiment, a structure is proposed to cleanly and easily replace the filter 33 without draining the raw water filled in the water tank 10.

More specifically, an opening 12 may be openly formed at an upper end of the water storage tank 10 in this embodiment, and a cover 13 for opening and closing the opening 12 may be installed in the opening 12 .

That is, in the state where the cover 13 is removed, the housing 31 accommodating the filter 33 used as the opening 12 is removed, or, conversely, the housing 31 accommodating the new filter 33 is inserted. can make it

Again, a pull hole 14 may be formed through the opening 12 . A traction member 37 to be described later can be operated as the traction port 14 .

Next, in addition to the configuration of the above-described embodiment, the filtration module 30 is fixedly installed on the filter support 40 and has a cylindrical shape with an open top to accommodate the housing 31 therein, and the lower surface thereof has a cylindrical shape. A jacket member 35 through which a second discharge port 35a communicating with the first discharge port 31a is formed through, a split pipe 36 extending or compressing in a vertical direction from an upper end of the jacket member 35, and the split pipe ( 36) may further include a traction member 37 extending to the outside through the traction hole 14 at the upper end.

The raw water discharged through the first outlet 31a of the housing 31 may flow out to the purified water tank 20 through the second outlet 35a, and the housing 31 accommodated on the fixed jacket member 35 It becomes a structure that is pulled up to the top according to the operator's operation.

The split pipe 36 is compressed and is made of a hollow elastic material that is elastically deformed when pulled upward, so that when the housing 31 is moved by the operator, the water storage tank 10 can move without contacting raw water. It plays the role of dualizing the interior space of

That is, when the upper end of the split pipe 36 fixed on the jacket member 35 is pulled upward, the compressed split pipe 36 extends upward to form a passage into the split pipe 36, The passage thus formed may be partitioned from the inner space of the water storage tank 10 .

On the other hand, the split pipe 36 may be made of a structure of a known bellows pipe type in addition to the hollow tubular shape of an elastic material.

A ring-shaped first sealing member 38 is coupled to an upper circumference of the split pipe 36, and a first magnet member 38a may be embedded in the first sealing member 38.

In addition, a second sealing member 15 having the same shape as the first sealing member 38 is formed on the inner surface of the upper end of the water tank 10, and the first magnet member 15 is inside the second sealing member 15. A second magnet member 16 having a polarity different from that of (38a) may be incorporated.

Accordingly, when the split pipe 36 is extended upward so that the first sealing member 38 comes into contact with the second sealing member 15, the adsorption force of the first magnet member 38a and the second magnet member 16 As a result, the first sealing member 38 and the second sealing member 15 are adsorbed and fixed airtightly, and thus, the elongation state of the split pipe 36 can be maintained.

Therefore, the operator can move the housing 31 to the inner passage of the divided pipe 36 without needing to separately fix the divided pipe 36, and workability is greatly improved, and the inner passage of the divided pipe 36 and the water tank ( 10) The inner space can be more reliably partitioned, so that the raw water of the water storage tank 10 does not flow into the inner passage of the divided pipe 36.

Next, the traction member 37 is a means for the operator to grip by hand for the extension operation of the split pipe 36 located inside the water tank 10, and the operator is exposed to the outside through the traction port 14. The split pipe 36 can be extended by pulling the traction member 37 by hand.

For example, the traction member 37 has one end fixedly coupled to the first sealing member 38 and the other end having a free end through the traction port 14 and a wire 37a and the wire 37a exposed to the outside. ) It may be exemplified as including a stopper 37b installed at the other end of the pulley 14 to limit the one-way movement of the wire 37a.

Accordingly, even if the operator releases the wire 37a from his/her hand, the stopper 37b is caught on the hauler 14 so that the wire 37a is not completely sucked into the water tank 10.

On the other hand, the filter 33 is generally made of a structure having an appropriate particle size, for example, activated carbon, zeolite, elvan silica sand, silica cornite, silver particles, etc., so that scales are adhered to the surface or various foreign substances are discharged There is a characteristic that does not become and remains.

Accordingly, in the present embodiment, by properly stirring the filter 33 using an agitating member 70 for agitating the filter 33 mounted on the housing 31, various scales, foreign substances, etc. are removed from the housing 31 together with the raw water. It has a structure that allows it to be discharged.

More specifically, the stirring member 70 is a vertical bar 71 coupled through the center of the plurality of diaphragms 32 and the cover 13, radially extending outward from the vertical bar 71, It may be exemplified as including a plurality of horizontal bars 72 disposed in the space between adjacent partition plates 32 and a silicon brush 73 formed on an outer surface of each of the plurality of horizontal bars 72 .

An upper end of the vertical bar 71 may pass through the cover 13 and be exposed to the outside, and a handle 74 is detachably coupled to the exposed upper end.

The horizontal bar 72 has a structure that digs into the inside of the filter 33, and the silicon brush 73 formed on the horizontal bar 72 burns the filter 33 in a line that does not damage the filter 33. are sexually contacted.

Accordingly, when a worker holds the handle 74 of the vertical bar 71 and applies rotational force to clean the filter 33, the horizontal bar 72 rotates in each filter loading room to agitate the filter 33, At this time, the silicon brush 73 detaches various scales adhered to the filter 33 from the surface of the filter 33, so that they can be discharged to the outside of the housing 31.

Thereafter, the operator completely removes the drinking water stored in the water storage tank 10 or the purified water tank 20 after manipulating the stirring member 70 to discharge scale and foreign substances to the outside and fills the water tank 10 with new raw water.

In this way, when cleaning the filter 33, the cleaning operation can be performed simply without removing the filter 33 to the outside unnecessarily, and furthermore, if the filter 33 is cleaned regularly, the The effect of significantly extending the lifespan can also be expected.

Hereinafter, a process of replacing the filter 33 in the water purifier of the present embodiment will be described with reference to the accompanying drawings.

First, as shown in FIG. 7 , the operator pulls the other end of the exposed wire 37a upward to extend the split pipe 36 .

At this time, when the first sealing member 38 and the second sealing member 15 are adsorbed and fixed to each other at a height at which the divided pipe 36 can no longer extend upward, the internal passage of the divided pipe 36 becomes a water storage tank ( 10) and the inner space are completely divided.

At this time, since the water tank 10 is filled with raw water, the passage of the split pipe 36 is also positioned as it is.

Again, if the inner space of the water tank 10 and the passage of the split pipe 36 are completely divided, the operator manipulates the dispenser to drain an appropriate amount of drinking water. The water level of the raw water filled in the passage of (36) is lowered.

At this time, the inner space of the water storage tank 10 and the passage within the divided pipe 36 are divided into two by the split pipe 36, so that raw water in the water storage tank 10 does not flow into the split pipe 36.

As shown in FIG. 8, when the water level goes down to a level at which the split tube 36 can be lifted up by hand or other tools, the operator removes the housing 31 on the jacket member 35 as shown in FIG. 9. Lift it up and discharge it to the outside through the passage of the split pipe 36 and the opening 12, insert a new filter 33 into the housing 31, and then place the housing 31 back into the jacket member 35 ) is combined internally.

Subsequently, as shown in FIG. 10, the operator slightly pushes the first sealing member 38 adsorbed and fixed to the second sealing member 15 by hand to separate it from the second sealing member 15. The split pipe 36 is compressed by the elastic restoring force, and the raw water filled in the water tank 10 can be introduced into the filtration module 30 again.

That is, when replacing the filter 33, the operation is possible without discharging all the water filled in the water tank 10, so that unnecessary waste of raw water is prevented and the raw water filled in the water tank 10 is affected by external factors. Since it is not exposed, unnecessary contamination can be prevented, and at the same time, the filter 33 replacement work is more simplified and workability is greatly improved.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
