Abstract
A water filter has a side wall member provided with an inflow port and an outflow port and has a cartridge mounting base, which is turnably borne to the near-bottom part of said side wall member; and a cartridge is detachably installed in said side wall member on said cartridge mounting base in a manner that the inflow port of said side wall member and the inflow port of said cartridge are connected and further the outflow port of said side wall member and the outflow port of said cartridge are connected.
Claims6
A filter comprising:
- a housing having an inflow port and an outflow port;
- a filter member;
- a cartridge for housing said filter member, said cartridge having an inflow port for flowing in raw water at a lower end of said cartridge and an outflow port for flowing out filtered water by said filter member in an upper end of said cartridge,
- said cartridge being detachably installed in said housing wherein the inflow port of said housing and the inflow port of said cartridge are coupled and the outflow port of said housing and the outflow port of said cartridge are coupled,
- said housing further comprising:
- a cartridge mounting member having a channel therein;
- a valve member in said channel for preventing water from flowing from an upstream position to a downstream position, the cartridge mounting member detachably coupling:
- (1) the inflow port of said cartridge and an output port of said channel upstream of said valve member, and (2) the inflow port of said housing and an inflow end of said channel downstream of said valve member;
- a wall having an opening for removably locating said cartridge within said housing;
- and
- a supporting member located within said housing having a channel therein for coupling the inflow port of said housing and said inflow end of said cartridge mounting member, said supporting member being rotatable about a horizontal axis so that said cartridge can be removed by way of said opening.
