Description

Unity filter apparatus for cold and hot water purifiers {Unity filter apparatus for cooler, water heater}

The present invention relates to a single filter device for cold and hot water purifiers, and more specifically, it is possible to reduce the working time and cost according to the filter replacement by allowing the raw water introduced from the tap to obtain drinking water with one filter. The present invention relates to a single filter device for cold and hot water purifiers to reduce manufacturing costs.

As the industry develops, not only pollution but also water quality problems for drinking water are seriously raised due to various pollutants.

In particular, since the contamination by various bacteria, iron, rust, and organic substances that are likely to be contained in domestic tap water is serious, the reverse osmosis type water purifier used directly connected to the tap water is recently used in many households.

The reverse osmosis water purifier is based on the osmotic phenomenon, ie, a natural phenomenon in which a liquid with a weaker concentration moves to a higher concentration through an osmotic membrane, and then artificially exerts a pressure on the concentrated solution to give water as a solvent in a high concentration solution. It is achieved by using an artificial action to move through the osmosis membrane toward the lower concentration.

1 is a view showing the configuration of a conventional general reverse osmosis type water purifier, as shown in the reverse osmosis type water purifier 10 is supplied with raw water from the faucet 20 is fine to about 5 microns First water purification step consisting of a pre-filter (30) to remove dust, debris, and various suspended substances through the filter, and chemicals such as carcinogens (THM), synthetic detergents, insecticides, etc. The second water purification step consisting of a carbon filter 40 for removing chlorine and the like, and a reverse osmosis membrane of 0.0001 micron to filter out heavy metals such as lead and arsenic, as well as sodium, bacteria, viruses, radioactive materials, and some of the drain pipe ( 55 is a third water purification step consisting of a membrane filter 50 to flow to the tap water 20 through the side, and a post filter 60 for removing unpleasant taste and smell, pigments, etc. The operation is performed in the fourth integer step.

In addition, a solenoid valve 70 and a pump 80 are installed in a flow path between the prefilter 30 and the carbon filter 40 to supply raw water while applying a predetermined pressure. In addition, the water passing through the post filter 60 is supplied and stored in the water tank 90 so that the user can taste through the outlet port not shown as needed.

However, the conventional reverse osmosis type water purifier made in this way, as described above, the filter provided in each step, that is, the pre-filter 30, the carbon filter 40, the membrane filter 50 and the post filter 60 is constant If it is used for more than one hour, the exchange period of these filters (30, 40, 50, 60) is different, so it is cumbersome to maintain and replace the filter frequently, and the management cost and water purifier accordingly It was a factor that raised the manufacturing cost.

In addition, since the conventional reverse osmosis water purifier is installed in the flow path between the prefilter 30 and the carbon filter 40 as described above, the pump 80 is provided to supply raw water by applying a predetermined pressure. There was a problem such as requiring a separate installation space.

In order to solve the above problems, the present invention is designed to replace the filter by providing a single cylindrical filter in which an inner nonwoven fabric layer, a solid adsorption layer, and an outer nonwoven fabric layer are sequentially stacked on the outer circumferential surface of the porous cylindrical filter cartridge core. And it can reduce the management cost, reduce the manufacturing cost of the water purifier, eliminate the pump, the installation space is unnecessary according to it, and furthermore, to provide a single filter device for cold and hot water purifier to make the water purifier compact The purpose is.

The object of the present invention described above is fixed to the upper surface of the fixed plate fixedly installed in the cold, hot water purifier is supplied with raw water through the supply hose from the tap water and various floating substances such as dust, debris, carcinogens (THM), synthesis Filters harmful chemicals such as detergents and insecticides, chlorine, heavy metals such as lead and arsenic, as well as sodium, bacteria, viruses, and radioactive substances, and removes unpleasant tastes, odors and pigments, and is used as drinking water. In configuring the filter device to be possible, the upper surface of the fixing plate is provided to be fixed in pairs spaced apart by a predetermined distance, the upper portion is formed in a cylindrical shape so as to be able to release the fixing according to the separation of the seating portion of the clamp equipped with a semi-circular mounting portion. At one end, an inlet is formed to be connected to a supply hose connected to the tap water so that raw water can be introduced therefrom. One side of the inlet is formed with an outlet for outflowing the purified water through the outlet hose to the water tank side, and the other end of the housing is opened and closed by a cover part that is screwed into the O-ring of the rubber material, and the inner peripheral surface of the housing and The outer circumferential surface is installed to have a predetermined space, one end of the rubber material O-ring is blocked by the outlet cap by the outlet cap member formed with a plurality of outlets protruding to the outer circumferential surface and the other end is fixedly blocked by the cap member 90-92wt% of a porous cylindrical filter cartridge core layer, an inner nonwoven layer wrapped around the outer circumferential surface of the core layer thereof, and an active carbon fiber wrapping the outer circumferential surface of the inner nonwoven layer so as to absorb raw water introduced through the inlet through the outer circumferential surface to purify it. And pulp binder and acrylic island in which wood pulp and bast pulp are mixed in a weight ratio of 20:80 to 80:20. 3 to 5 wt% of a binder or any combination thereof and a solid adsorption layer composed of an additive polyamide-based modified resin 3 to 5 wt% and an outer nonwoven fabric layer covering the solid adsorption layer are sequentially stacked. Achieved by including a cylindrical filter.
