Description

MULTI-STAGE COMPLEX FILTER APPARATUS FOR WATER PURIFIERS AND WATER PURIFIERS COMPRISING THE SAME }

Embodiments relate to a multi-stage complex filter device for a water purification device and a water purification device including the same. More specifically, the embodiments provide a multi-stage type for a water purification device that enables customized water purification optimized for the installation environment and use by selecting and employing the type of raw material and filter according to the water quality component that varies depending on the region and place and configuring a complex filter device. It is about the technology related to the composite filter.

As environmental pollution becomes more serious, in general, tap water is not directly used as drinking water at home and work, but purified water using a separate water purifier is used as drinking water. Such a water purifier is configured to receive raw water, pass it through various filters, and then discharge it, and various types and types of filters are used depending on the purpose of purified water and the state of the raw water.

However, the conventional water purifier has been developed only for the purpose of producing drinking water that can be drunk by receiving purified water in a cup, and it is necessary to wash rice or vegetables in the kitchen to cook food or wash dishes, and hygiene to wash the body. There have been few studies on water purifiers for water use.

Due to this, users who want to purify the drinking water have the inconvenience of receiving water from the drinking water purifier and moving it to the sink to cook rice and use it for soup. In addition, even when purified water is required for rinsing after washing dishes, there is an inconvenience of receiving and using water from a water purifier, so most users give up using purified water for washing dishes. In the case of water purification for sanitary water, although some water purification devices for showers have been developed, most of them have only a function of removing rust, so the effect is fragmentary.

On the other hand, conventional water purifiers have been developed mainly for the purpose of purifying cold water from tap water, and materials such as cartridges, housings, and sedimentation filters used in water purifiers have been manufactured and processed based on petrochemical products. For that reason, these conventional parts may generate environmental hormones and the like when immersed in hot water for a long time to purify the hot water of tap water, and may cause unexpected chemical changes due to heat.

In addition, the conventional water purifier filter is structured to push water through from the outside (outer diameter) to the inside (inner diameter) of the filter, so that the part through which water actually passes is only about 15 mm regardless of the size (width) or length of the filter. Since it is only inside and outside, the size of the filter has no meaning in appearance and is merely a device for passing a lot of water.

Due to these fatal disadvantages, the conventional water purifier filter uses a one-time purification method that inevitably results in incomplete water purification even if the flow rate is high or the water quality is slightly poor. For example, conventionally, the same type of filter is used whether an old building or a recently built building is used, and the difference in water quality between a collective residential facility such as an apartment and a small house such as a detached house is not considered. In addition, regardless of the difference in size or performance of the filter, filter replacement is performed by applying the filter fastening method and replacement method of the time when the water purifier was first introduced in Korea.
