[Claims]
A pressure maintaining mechanism for automatically discharging fluid from the fluid flow path when the fluid pressure in the fluid flow path becomes higher than a predetermined pressure and maintaining the fluid pressure at a predetermined pressure or less; Valve that also has a stagnation prevention mechanism that can positively discharge fluid that stagnates as needed.
The valve includes a valve box, a communication port formed in a wall of the valve box and communicating with a fluid flow path, a fluid vent formed in the valve box and communicating with the outside, and the communication port. A valve body that opens and closes, a biasing unit that presses the valve body against the communication port with a predetermined biasing force, and an opening and closing unit that opens and closes the valve body from outside the valve box; 2. The valve according to claim 1, wherein said urging means is said urging means, and said retention preventing mechanism is said opening / closing means.
3. A raw water inlet, a water purification section for purifying raw water, a purified water discharge port for discharging purified water, and a flow path flowing from the raw water introduction port to the purified water discharge port via the purified water section. A water purifier comprising the valve according to claim 1 in the flow path.
4. The raw water purifier has a raw water inlet, and the valve communicates with the outside of the water purifier at a position lower than the raw water inlet in a raw water flow path between the raw water inlet and the raw water inlet. The water purifier according to claim 3, wherein the water purifier is disposed in the formed drainage opening.
5. The water purification section has a water purification outlet, and the valve communicates with the outside of the water purifier at a position lower than the water purification outlet in a water purification flow path between the water purification outlet and the water purification outlet. The water purifier according to claim 3, wherein the water purifier is disposed in the formed drainage opening.
6. The water purifier according to claim 3, wherein the opening and closing operation of the opening and closing means is manually performed.
また、前記浄水器は前記原水導入口において同浄水器を蛇口に取り付ける取付部材を備えている。上述の本件発明では、浄水器がコンパクトであるため、例えばキッチンなどの蛇口に直接取り付けても、同浄水器の下方に十分なスペースを確保できる。
Further , the water purifier includes a mounting member for attaching the water purifier to a tap at the raw water inlet. In the present invention described above, since the water purifier is compact, a sufficient space can be secured below the water purifier even when the water purifier is directly attached to a faucet such as a kitchen.
また、前記浄水器は原水を直接吐出する原水吐出口を有し、前記原水導入口と前記浄水部との間の原水流路は、前記浄水部への流路と前記原水吐出口への流路とに分岐しており、その分岐部分には、原水の流れを前記浄水部と前記原水吐出口とに切り換える切換え手段が配されている。
Further, the water purifier has a raw water discharge port for directly discharging raw water, and a raw water flow path between the raw water introduction port and the water purification section has a flow path to the water purification section and a flow path to the raw water discharge port. And a switching means for switching the flow of the raw water between the water purification section and the raw water discharge port.
また、前記浄水器は本体容器がプラスチックで形成されており、さらに、前記浄水部には濾過材として中空糸膜が装填されている。本件発明は上述したように、内部の水圧を所定圧力以下に維持できるため、浄水器の本体容器がプラスチック製であり、また、浄水部に柔軟性をもつ中空糸膜が装填されていても、それらの部材が変形や損傷することがない。
Also, before Symbol water purifier is formed body container in plastic, further to the water purification unit hollow fiber membranes is loaded as a filtering material. As described above, the present invention can maintain the internal water pressure at a predetermined pressure or less, so that the main body container of the water purifier is made of plastic, and even if the water purification section is loaded with a flexible hollow fiber membrane, These members are not deformed or damaged.
