Liquid containing vessel
A liquid containing vessel includes a liquid containing chamber configured to contain a liquid. The liquid containing chamber has a filter chamber with a filter through which the liquid is configured to pass, and a low pressure chamber having a pressure that is lower than atmospheric pressure.
1. A liquid containing vessel comprising:
a liquid containing chamber containing a liquid,
the liquid containing chamber having a filter chamber with a filter through which the liquid is configured to pass, and a low pressure chamber having a pressure that is lower than atmospheric pressure.
2. The liquid containing vessel according to claim 1 , wherein
the low pressure chamber is arranged such that at least a portion of the low pressure chamber overlaps with the filter chamber in a projection direction where a projection area of the filter chamber to the low pressure chamber is maximized.
3. The liquid containing vessel according to claim 1 , wherein
the length of a liquid inflow region where the liquid is configured to flow into the filter chamber in a vertical direction is shorter than the length in a direction that intersects with the vertical direction.
4. The liquid containing vessel according to claim 1 , further comprising:
a supply member defining the liquid containing chamber by being joined with a containing chamber member, and including a liquid supply opening through which the liquid is configured to flow out from the liquid containing chamber to an outside; and
a second supply member defining the filter chamber and the low pressure chamber, and being connected, when the supply member is a first supply member, with the first supply member,
at least a portion of the filter chamber and the low pressure chamber of the second supply member being formed using a shared member.
5. The liquid containing vessel according to claim 4 , wherein
the second supply member is attachably and detachably connected with regard to the first supply member.
6. The liquid containing vessel according to claim 4 , wherein
the containing chamber member is formed using a flexible member that is deformable while the liquid flows out from the liquid containing chamber, and
the second supply member that defines the filter chamber including at least one convex section that defines a flow path in which the liquid in the liquid containing chamber is configured to flow to the filter chamber by passing through the filter between the containing chamber member and the second supply member while abutting with the containing chamber member that is deformable.
7. The liquid containing vessel according to claim 4 , wherein
the filter of the filter chamber extends along a direction that intersects with a deforming direction of the containing chamber member, and the filter chamber includes an abutting section that is abuttable with regard to the filter that deforms while the containing chamber member deforms.
8. The liquid containing vessel according to claim 4 , wherein
the filter chamber defines a flow path in which the liquid is configured to flow to the first supply member side, and
a cross sectional area of the flow path at a first position that is close to the first supply member is larger than a cross sectional area of the flow path at a second position that is farther from the first supply member than the first position.
9. The liquid containing vessel according to claim 1 , wherein
the low pressure chamber is disposed at a position where a proportion of gas that is dissolved in the liquid with regard to the liquid in the filter chamber is reduced.
10. The liquid containing vessel according to claim 1 , wherein
a film is disposed in the low pressure chamber to blocked off an opening section of a concave region of the low pressure chamber.
11. The liquid containing vessel according to claim 10 , wherein
the film is configured such that gas dissolved in the liquid to pass therethrough.
12. A filter unit disposed in a liquid containing chamber containing a liquid, the filter unit comprising:
a filter chamber with a filter through which the liquid is configured to pass;
a low pressure chamber having a pressure that is lower than atmospheric pressure; and
a connected section configured to be attached and detached with respect to a connecting section provided in a supply member supplying the liquid from the liquid containing chamber to outside.
13. The filter unit according to claim 12 , wherein
a film is disposed in the low pressure chamber to blocked off an opening section of a concave region of the low pressure chamber.
14. The filter unit according to claim 13 , wherein
the film is configured such that gas dissolved in the liquid to pass therethrough.
15. A liquid containing vessel comprising
the filter unit according to claim 12 .
16. A filter unit disposed in a liquid containing chamber containing a liquid, the filter unit comprising:
a filter chamber with a filter blocking off a first opening section disposed in a first concave region; and
a low pressure chamber with a film blocking off a second opening section disposed in a second concave region, the low pressure chamber having a pressure that is lower than atmospheric pressure,
the filter chamber and the low pressure chamber being arranged with a front and back relationship to each other.
17. The filter unit according to claim 16 , wherein
the film is configured such that gas dissolved in the liquid to pass therethrough.
18. A liquid containing vessel comprising
the filter unit according to claim 16 .
