Abstract: The present invention relates to a pitcher-type water purifier, comprising: a pitcher body including a cylindrical casing having a bottom and a partition for partitioning the inside of the casing; a pitcher lid liquid-tightly closing an opened top end of the pitcher body; and a water purifying cartridge detachably attached to an opened attachment part in the partition.

Abstract: A water filter cartridge is reduced in fluctuation in filtration flow rate or in filtration performance due to activated carbon, and can exhibit stable performance even at the time of large scale production; and a water purifier is equipped with the water filter cartridge. A water filter cartridge having particulate activated carbon filled in a case for accommodating a filtering material in which the ratio of the total mass of particulate activated carbon having a particle size of 0.3 to 4.0 mm relative to the total mass of activated carbon is 97% by mass or more, and, in a particle size distribution which represents the relationship of the mass ratio of activated carbon relative to the particle size of activated carbon, a peak at which the mass ratio is 31% by mass or more does not appear in a particle size range of from 0.3 to 4.0 mm.

Abstract: A water purification cartridge is detachably provided inside a water purifier, which includes: a plurality of single cartridges, each of which includes a bottomed cylindrical casing body; and one or more ceiling wall portions which block upper end openings of the plurality of single cartridges, wherein the inside of the plurality of single cartridges becomes a filter medium storage portion, and wherein the plurality of single cartridges is disposed in the lateral direction and is detachably connected to each other.

Abstract: A pot type water purifier capable of obtaining a mixed liquid including purified water and an additive uniformly mixed in the purified water without the need of stirring in a container such as a cup after pouring out. The pot type water purifier of the present invention includes a body container with internal space and an upper opening; a raw water reservoir provided to an upper part of the internal space; a water purification cartridge communicating with the raw water reservoir; a purified water reservoir formed below the water purification cartridge, the purified water reservoir housing purified water resulting from filtration through the water purification cartridge; a pouring lip for purified water in the purified water reservoir; and stirring means provided to the body container to stir the purified water.

Abstract: A structure for an opening section closed by a net through which fluid flows. The opening section is provided in a vertical wall so as to rise to the vertical wall side from the corner formed between the vertical wall and a horizontal wall. A downward protruding rib is provided on the lower side of the opening section. The lower edge of the net is provided so as to be affixed to at least the rib.

Abstract: The objective of the present invention is to provide a water purification cartridge with excellent water permeability and processing capability. The present invention relates to a water purification cartridge positioned between a raw water reservoir and a purified water reservoir of a water purifier and having a container to accommodate an adsorbent and a hollow-fiber membrane for filtering raw water. Such a water purification cartridge includes an adsorber section in which the adsorbent is positioned and which has a water collector section through which the water filtered by the adsorbent flows; a hollow-fiber membrane section in which the hollow-fiber membrane is positioned and which is located on the downstream side of the adsorber section and the water collector section; and an air outlet positioned on the upper side of the container and connected to the space in the water collector section.

Abstract: A gravity-filtration water purifier includes a vessel body, a plurality of partition units that are detachably attached to the vessel body and that vertically partition at least a part in the vessel body into a plurality of stages, and a water filter cartridge that is mounted on each of the plurality of partition units and that purifies water on the partition unit and supplies the purified water to below the partition unit. Here, the gravity-filtration water purifier purifies raw water supplied to the uppermost stage using its own weight.
