Description

Home water purification device {WATER PURIFIER}

The present invention is a device for purifying and sterilizing domestic water supplied to homes. More specifically, as the water flowing in through the water inlet passes through the cartridge part, foreign substances in the water are removed by sieving and adsorption, and the flow path inside the sterilizing member is removed. This relates to a household water purification device that is continuously sterilized by UV-C LED while flowing along the water and is discharged to the outside through a water outlet with bacteria etc. removed, and can minimize water pressure loss.

In general, a water purification device is a device for purifying raw water such as tap water or mineral water. Based on a water purification method that includes processes such as precipitation, filtration, and disinfection, activated carbon, KDF55, cation resin, and vitamin C filter are added to remove the taste from raw water. , removes harmful substances such as odor substances, heavy metals, residual chlorine, bacteria and viruses, and leaves substances beneficial to the human body such as minerals, providing residential water that users can use.

In order to supply residential water to users, the government purifies water through water treatment facilities at each local water purification plant. Purified domestic water is supplied to each area and facility in need of water through water pipes.

However, as water pipes age, rust forms on the inner surface of the water pipes and other foreign substances enter the water pipes. As a result, the residential water moving through the water pipes may contain unsanitary harmful components and be supplied to each area and facility. there is.

The government and local governments are maintaining pipes by replacing and rehabilitating old water pipes, but due to budgetary issues, it is difficult to completely replace old water pipes, and water pipes within buildings and houses are not easy to maintain. There is a problem that it is not. Water supply pipes within buildings and houses are managed by individual owners, and maintenance of pipes buried inside building walls or under the land involves large costs, and in the case of apartment complexes, there are many stakeholders, making it difficult to proceed with the work. .

Therefore, visible reddish rust or turbid substances may appear in tap water from kitchens and bathrooms of old buildings and houses, and when the concentration of residual chlorine is low or absent, such as in areas where groundwater is used or at the end of water supply pipes, harmful organic substances or , bacteria, etc. may also be included. Sediment filters or membrane filters are sometimes used to prevent water accidents caused by harmful substances, but if tap water is not used for a long time, the residual chlorine concentration may decrease or disappear, causing mold or bacteria to grow inside the filter. As a result, the drinker's skin diseases such as atopy and acne may worsen or the drinker's health may be threatened.

Additionally, users have no way to check whether the household water reaching them is supplied through clean water pipes or old water pipes.

Therefore, due to the uncertain tap water quality, users want to install additional water purification equipment in each home or place of use to remove foreign substances and bacteria contained in the water.

Conventional water purification equipment includes sediment filters, activated carbon filters, water softeners, and membrane filters, depending on their functions.

However, since each filter performs only fragmentary functions, such as the sediment filter removing solids, the activated carbon filter removing taste and odor, and the water softener removing heavy metals, each filter does not satisfy the comprehensive water purification function. In addition, the membrane filter is a reverse osmosis method that prevents contaminants from passing through the membrane and can guarantee water purification performance above a certain level. However, it cannot guarantee appropriate water pressure for use as domestic water, so it does not satisfy usability. Therefore, a comprehensive management solution that can satisfy both water purification functions and usability is needed.

In addition, looking at a conventional UV lamp device, its sterilization performance depends on the contact time between water and ultraviolet rays, so water was placed in a water tank and irradiated with ultraviolet rays for a certain period of time to ensure sterilization efficiency. In order to sterilize tap water supplied at a pressure of about 1 to 3 kgf/cm ² while maintaining the water pressure, a water tank to store the water and a separate pump facility to pump the water back are required. Therefore, it is not difficult to introduce a process to sterilize water with ultraviolet rays in addition to drinking water purifiers that do not require water pressure in ordinary houses or buildings.

Therefore, regardless of the age of the water supply pipes in the house, which varies depending on the region, it can be easily installed in each home and living facility, and it effectively purifies and sterilizes foreign substances contained in the supplied domestic water, thereby providing the user with The development of water purification devices that can provide hygienic drinking water is on the rise.

The direction in which water moves through the fourth upper flow path 554 to the second housing outlet hole 527a may be referred to as the tenth direction D10. The direction in which water flows into the upper filter 600 coupled to the second housing water outlet hole 527a may be referred to as the 11th direction D11.

The upper filter 600 may include a first upper filter housing 610. The upper filter 600 may include a second upper filter housing 620 disposed within the first upper filter housing 610. The second upper filter housing 620 may include a plurality of microholes (not shown).

The upper filter 600 may include an upper filter member 630 accommodated in the second upper filter housing 620. For example, top filter element 630 may include vitamin C. The upper filter member 630 may be discharged to the outside of the second upper filter housing 620 through a micro hole (not shown) of the second upper filter housing 620. For example, the upper filter member 630 may be discharged to the outside of the second upper filter housing 620 by water pressure.

The upper filter 600 may include an upper filter passage 640 formed between the first upper filter housing 610 and the second upper filter housing 620.

The direction in which water moves along the upper filter passage 640 may be referred to as the twelfth direction D12. For example, water flowing along the twelfth direction D12 may come into contact with vitamin C discharged within the second upper filter housing 620. When water comes in contact with vitamin C, vitamin C can bind to residual chlorine in the water and remove residual chlorine.

The direction in which water is discharged out of the upper filter 600 may be referred to as the thirteenth direction (D13).

The water moves sequentially from the first direction D1 to the thirteenth direction D13 and can be supplied to the user after being purified and sterilized.

Any or other embodiments of the present invention described above are not exclusive or distinct from each other. In certain embodiments or other embodiments of the present invention described above, each configuration or function may be used in combination or combined.

It is obvious to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.
