In addition, the precipitation filter is fixed by rolling the nonwoven fabric filled therein in the form of a roll.

In addition, the sedimentation filter, the re-filtration filter and the purified water filter is composed of a synthetic resin or stainless steel and the chamber and the upper cap screwed together, the chamber accommodates the nonwoven fabric or various filter media while the lower one side for the inflow of water In addition to the inlet is formed and a rubber ring is installed in the connection portion with the upper cap, the upper cap is provided with an outlet of the 'b' shape is formed at the end of the outlet for the discharge of water in the horizontal direction.

In addition, the upper cap is provided with a rubber ring in the connection portion with the chamber and the outlet is provided in the vertical direction in the center thereof, the outlet for the discharge of water is formed at the tip.

In addition, the inlet of the chamber and the inlet of the outlet of the upper cap are each provided with a stainless steel net.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the water direct type water purifier of the present invention, which is configured to purify tap water while passing through several stages of filters, the water direct connection water purifier 1 is composed of a plurality of filters that sequentially purify water. The filter is composed of a sedimentation filter 10, a re-filtration filter 20 and a water purification filter 30 according to the purpose, connecting the raw water line and the sedimentation filter 10, and the sedimentation filter 10 and the Connection pipe 40 for supplying purified water by connecting the re-filtration filter 20 and the purified water filter 30 is further included.

Here, the sedimentation filter 10 is to primarily filter the raw water introduced from the raw water line of the tap water, the lower portion of the sedimentation filter 10 is filled with a non-woven fabric (2), of the sedimentation filter 10 The upper part is filled with charcoal 3 having 5-10 mm particles.

The re-filter 20 is arranged in a state in which the charcoal 3 is filled to filter the water passing through the precipitation filter 10, the re-filter 20 is preferably installed about two You can increase the number as needed.

The water filter 30 is a structure filled with alum (4) having 5-8mm particles to filter bacteria and fine impurities and water to pass through a plurality of the re-filtration filter 20.

In addition, the charcoal 3 is a kind of charcoal that is processed by external heat, and the charcoal made by burning wood directly, or by reprocessing the charcoal 3, has improved absorption but differs from activated charcoal having a lot of dust and no alkalinity. It is possible to purify the water filtered through (3).

Therefore, the water direct type water purifier 1 having the above structure firstly feeds the raw water supplied from the raw water line of the tap water into the sedimentation filter 10 through the connection pipe 40, and then the sedimentation filter 10. The water passed through is primarily filtered, and the water is filtered through the refiltration filter 20 twice to further purify water, and finally, as the water passes through the purified water filter 30, the purified water is completed. Supplied to the user.

On the other hand, the non-woven fabric (2) is installed in the lower portion of the precipitation filter 10, as shown in Figure 2, the non-woven fabric 2 is rolled in the form of a roll to be filled in the interior of the precipitation filter 10, porous The nonwoven fabric 2 is rolled up in the form of a roll to primarily filter the raw water flowing in, and various impurities or suspended matter contained in the water passing through the nonwoven fabric 2 can be effectively filtered.

In addition, the filter constituting the water direct type water purifier 1, as shown in Figure 3, the filter is composed of a cylindrical chamber 50 and the upper cap 60 for sealing the chamber 50 and The chamber 50 and the upper cap 60 are made of synthetic resin or stainless steel, and an inlet 51 through which water is introduced is formed at one lower side of the chamber 50, and one side of the upper cap 60. An outlet 61 through which water passing through the filter is discharged is formed, and the pressure limit of the filter is preferably designed to be 6 kgf / cm 2 or 125 PSI.

Here, an embodiment of the filter will be described with reference to FIG. 4, wherein the precipitation filter 10, the re-filtration filter 20, and the water filter 30 are made of synthetic resin and screwed together with the chamber 50. Consists of the upper cap 60, the chamber 50 accommodates the nonwoven fabric 2 or a variety of filter media, the lower side is formed with an inlet 51 for the inflow of water and a connection with the upper cap 60 A rubber ring 70 is installed in the upper cap 60, and the outlet cap 62 is provided with an outlet passage 62 having a '-' shape, and an outlet 61 for discharging water in the horizontal direction is formed at the tip thereof.

And, another embodiment of the filter with reference to Figure 5, the precipitation filter 10, the re-filtration filter 20 and the water filter 30 is made of a stainless steel chamber 50 and a synthetic resin Consists of an upper cap 60, the upper cap 60 is provided with a rubber ring 70 in the connection portion with the chamber 50, and is provided with an outlet passage 62 in the vertical direction at the front end thereof An outlet 61 is formed for the discharge of water.

In addition, the inlet 51 of the chamber 50 and the inlet of the outlet 62 of the upper cap 60 are each provided with a stainless steel net (80). The stainless steel net 80 filters the various impurities or suspended substances contained in the water passing through the inlet 51 of the chamber 50 and the inlet of the upper cap 60, and thus the inlet 51 and the outlet 61. It is possible to prevent the blockage of the connecting pipe 40 connected to the filter in advance and to operate the water purifier efficiently.

Therefore, the water direct type water purifier 1 having the above structure has fine impurities and fine particles due to the excellent absorption and sterilization power of the white charcoal 3 having the first filtered water embedded in the plurality of filters while passing through the nonwoven fabric 2. Bacteria as well as odors are filtered out.

In other words, unlike the reverse osmosis membrane (RO Membrane), which filters even minerals in the water, various minerals are made of white charcoal (3) that does not filter. According to the 4th), the water is filtered more clearly, and even the smell of tap water is removed.

And, if the white coal (3) of the water direct type water purifier (1) adjusts the valve so that the flow rate is 0.5-1 gpm irrespective of the strength of the water pressure, the ideal time for water to contact while passing through the filter medium is secured sufficiently. As a result, unlike activated carbon, which has a large filtration function depending on the temperature and flow rate of water, it is filtered regardless of the extreme change in water temperature. At this time, the water is weakly alkaline water approaching PH 7.38-7.45. Becomes

In addition, it is safe for everyone because the elderly or children do not have to worry about accidentally drinking strong alkaline water in the alkaline water of various stages artificially generated by the electrolysis of the ion water purifier. Natural water and weakly alkaline water can be obtained by the filter medium.

In addition, the charcoal (3) also contains the impurities inherent in the filtration process like the activated carbon of the existing water purifiers are always wet, so the periodic exchange is the same, but the difference is that the charcoal (3) Even when the pH was measured after about 10 months without using), the pH was slightly lowered but still slightly alkaline water was produced.

In addition, activated carbon is included in each of two filters, namely free carbon and post carbon, among the filters installed in the conventional water purifier. Since the actual inner diameter of the filter is about 5.2 cm in diameter and a cylinder of about 20 cm in length, The total amount of activated carbon contained in the two filters is approximately 250 cm³-300 cm³, but the filter used in the present invention is about 8 cm in diameter and 23 cm in length. The combined amount is approximately 820 cm³-850 cm³, with about three times as much filter media embedded in each set. It helps to produce more water and weakly alkaline water.

On the other hand, the water direct-type water purifier 1, when the water supplied is filtered using a multi-stage filter, the water flows from the bottom up even at a low water pressure, it is already settled in the lower portion of the filter or down when the operation stops Retaining impurities are prevented from going to the next filter or withdrawing even if using a filter.

In addition, since the upper cap 60 is a simple rotary opening and closing type, there is no need for trouble or repair, and when the water direct type water purifier 1 is installed, a plurality of filters may be fixed to a bracket to be installed safely and concisely. When it is desired to change the filter media directly, it is easier and easier to freely change the filter media without being skilled.

In addition, the user can not only replace the filter medium directly, but also can change the next time according to their environment and the quality of the raw water when the exchange, thereby maximizing the efficiency and economy at the same time, and easily obtain the filter medium on the market Maintenance costs are greatly reduced.

In addition, the water direct type water purifier 1 can be installed anywhere, but mainly in a sink, so that it is not exposed to the outside and does not take place or harms aesthetics, and utilizes the cold / hot function of other water purifiers that have been used previously. If desired, it is also possible to simply connect the tube of water last passed through the filter to the reservoir of the existing water purifier without moving the existing water purifier.

In addition, a three-way T-shaped tube connected to the water pipe that passed through the filter last can be used as cooking water by simply connecting the faucet with a simple operation of the sink, so that the sink and the water direct connection (1) can be easily connected. Can be.

Therefore, it is possible to simply supply more clean water to the user by purifying water passing through the water direct type water purifier 1 in multiple stages using a plurality of filters.

As described above, according to the water direct type water purifier according to the present invention, water can be purified more effectively by filtering water supplied using a multi-stage filter, and the water direct type water purifier has a simple structure to maintain and repair the water purifier. It is convenient, economical because it does not cost a lot of manufacturing and use, there is an advantage that it is convenient to replace the various filter materials contained in the filter.
