BACKGROUND OF THE INVENTION
The present invention relates to a water purifier and a water purifier shower.
[0002]
[Prior art]
Chlorine in tap water is added as drinking water at a water purification plant in accordance with the Water Supply Law for odor removal and sterilization. However, chlorine is also known to have an effect of destroying proteins, and therefore a water purifier has been invented to remove residual chlorine contained in tap water before use. In recent years when rivers and groundwater, which are raw water for tap water, have become seriously polluted, the awareness of the environment and health has increased, and not only the original chlorine has been removed, but also the requirements for water purifiers have changed. For example, it is needless to say that a stronger sterilizing action is required, and delicious water and water with good health have been demanded. Furthermore, in order to obtain health and healing at hand, there has been a demand for a sustained release of drugs, a hot spring effect, and a water purifying shower with fragrance.
[0003]
By the way, conventionally, as this kind of water purifier and water purifier shower, a filter cartridge is detachably installed in a water purifier body of a required shape having a water supply port and a water intake port. The filter cartridge has a basic structure in which a required filter is filled in a substantially container-like housing having a water intake port.
As an example of the cartridge, Japanese Patent Application Laid-Open No. 11-267635 (Patent Document 1) includes metal fibers and a calcium sulfite sealed in a non-woven fabric in a substantially container-shaped housing having a water intake. The thing filled with the filter for water purification processing which becomes and the filter for water quality adjustment containing tourmaline is proposed. Japanese Patent Laid-Open No. 2002-239539 (Patent Document 2) discloses that a housing having a water intake port is composed of an outer case and an inner case, and activated carbon is interposed between the inner and outer cases. It has been proposed that the inner case is filled with a non-woven fabric and the inner case is filled with a hollow fiber membrane. Furthermore, JP-A-2002-301111 (Patent Document 3) includes a cylindrical filter provided with an internal flow path in a housing provided with a water intake port, and the filter has one end thereof. There has been proposed one in which the initial filtration resistance is further reduced toward the other end.

[Problems to be solved by the invention]
However, while the conventional example configured as described above has effects such as dechlorination, deodorization, dust removal, antibacterial effect, and reduction of filtration resistance, the required filter is filled in a container-like housing having a water intake port. Therefore, when replacing the cartridge, the cartridge housing material must be discarded, which is problematic from the viewpoint of the global environment. In addition, the structure is complicated and the production is not only very troublesome and time-consuming, but also the cost is increased as a whole, and the filtering area is inevitably restricted by the type, number, and amount of filter. It cannot be done. For this reason, not only the life of the filter is short, but the water supplied from the water supply causes a large filtration resistance in the water purifier and the water purifier shower, and the smooth water purification treatment is likely to be hindered.
