Abstract

DC60 (01/03/45) This invention is intended to provide a pitcher-type water purifier and machine. Filters for water purification, which can absorb and remove chemicals such as chlorine and the like. out of raw water, bacteria can be eliminated and even if filtered water is stored for a long time It is also able to prevent bacterial breakdown and can provide filtered water which is Increased safety in a short time. The pitcher type water purifier (1) consists of a divided jug body at the top. and below which serve as raw water storage (1a) and filtered water storage (1b), wherein the jug (10) has an opening for pouring filtered water (11b) in contact with the filtered water retention (1b); and the water filter cylinder (20) that is arranged in such a way that it can be replaced above the area one from the raw water catchment (1a) to the filtered water catchment (1b) or from the filtered to raw water storage and raw water inlet (23) that opens to raw water storage (1a) and filtered water discharge (24) which opens to filtered water storage ( 1b). In the filter cylinder (20), the sorbent (26) is loaded into the upper layer of the internal area in contact with the raw water inlet (23), and the hollow fiber membrane (27b) is loaded into it. Its bottom layer and sigma packing density of hollow fiber membranes range from 25 to 58%. And removing chemicals such as chlorine and similar substances from raw water, bacteria can be eliminated and even if the filtered water is stored for a long time. It is also able to prevent bacterial rupture and can provide more safe filtered water in a shorter period of time. The pitcher type strainer (1) consists of a jug divided into upper and lower sections serving as raw water reservoir (1a) and filtered water storage (1b). said to have an opening for pouring filtered water (11b) in contact with the filtered water reservoir (1b); and filter cylinders (20) that are arranged in such a way that they can be replaced over an area from the raw water catchment (1a) to the filtered catchment (1b) or from the catchment. Filtered water goes to the raw water catchment and raw water inlet (23) that opens to the raw water catchment (1a) and filtered water discharge port (24) which opens to the filtered catchment. Then (1b) in the filter cylinder (20) the sorbent (26) is loaded into the upper layer of the internal area in contact with the raw water inlet. (23) and the hollow fiber membrane (27b) is loaded into its lower layer and the sigma packing density of the hollow membrane ranges from 25 to 58%.

Claims (9)

1. Filter cylinder (30) for the pitcher type water purifier (1) that can be placed interchangeably. can be regenerated during the raw water storage section and filtered water storage raw water storage and storage Dried filtered water is bounded by the area above. and a bottom that divides the interior of the jug with an opening for pouring filtered water. Where the filter cylinder has a raw water inlet (23) which opens to the distilled water reservoir and filtered water inlet (24) which opens to the filtered water catchment. The upper layer of the internal region is filled with sorbent (26) and is in contact with the raw water inlet. Its lower layer is filled with hollow fiber membrane (27b), and the filling density 0 of the hollow fiber membrane is 25-58 % The filling density is defined as 0 (%) -{(axF)s} x 100, where A= cross-sectional area of the outer diameter of the hollow membrane, F = number of membrane openings. hollow fibers and S= cross-sectional area of the filling gap of the central fiber which defines the unique feature that the upper layer (51) containing the absorbent and the lower layer (52) filled with hollow fibers can be separated from each other through the use of spiral overlap. 2. Filter cylinder for jug type water purifier according to claim 1, which specifies the specific feature that the filter cylinder has a bar configuration.
