Abstract

A drain strainer assembly includes a housing having a circular cross-section, with an inlet port, an outlet port, and a plurality of first engagement tabs. The drain strainer assembly also includes a strainer member assembly having a circular cross-section. The strainer member assembly includes a strainer member with a solid front surface having a handle and a plurality of second engagement tabs interlocked with the first engagement tabs on the housing. The strainer member also includes cylindrical strainer sidewalls defining a circular opening at the back of the strainer member, and has an upper conduit aligned with the inlet port of the housing. The strainer member assembly also includes a circular strainer disk coupled to the strainer member with a fastener and covering the circular opening at the back of the strainer member.

First claim

What is claimed is:

1. A drain strainer assembly comprising:
a housing having a circular cross-section, the housing comprising an inlet port, an outlet port, and a plurality of first engagement tabs; and
a strainer member assembly having a circular cross-section, the strainer member assembly comprising:
a strainer member with a solid front surface having a handle and a plurality of second engagement tabs interlocked with the first engagement tabs on the housing, the strainer member further comprising cylindrical strainer sidewalls defining a circular opening at a back of the strainer member and having an upper conduit aligned with the inlet port of the housing; and
a circular strainer disk coupled to the strainer member with a fastener and covering the circular opening at the back of the strainer member,

wherein the handle is an elongated handle that extends beyond the circular cross-section of the strainer member assembly and the plurality of second engagement tabs are located on the handle, wherein the second engagement tabs being positioned outside of the first engagement tabs and the handle is aligned with the inlet port when the second engagement tabs are interlocked with the first engagement tabs.

2. The drain strainer assembly of claim 1 , wherein the housing comprises a plurality of primary mounting holes through which fasteners may be inserted to secure the housing to a structure.

3. The drain strainer assembly of claim 2 , wherein the housing further comprises an optional secondary mounting hole.

4. The drain strainer assembly of claim 3 , wherein the primary mounting holes and secondary mounting holes are configured to enable a retrofit installation of the drain strainer assembly.

5. The drain strainer assembly of claim 1 , wherein the strainer member assembly further comprises a sealing member.

6. The drain strainer assembly of claim 5 , wherein the sealing member comprises a circular o-ring located within a corresponding groove in the cylindrical strainer sidewalls of the strainer member.

7. The drain strainer assembly of claim 1 , further comprising a label on the handle of the strainer member, the label indicating the correct orientation of the strainer member assembly within the housing.

8. The drain strainer assembly of claim 1 , wherein the fastener comprises an attachment pin or a hinge mechanism.

9. A vehicle galley comprising a counter surface having a catch basin disposed therein, the catch basin being fluidly coupled to a first conduit attached to a support wall, a circular drain strainer assembly attached to the support wall, and a second conduit attached to the support wall, the circular drain strainer assembly comprising:
a housing having a circular cross-section, the housing comprising an inlet port fluidly coupled to the first conduit, an outlet port fluidly coupled to the second conduit, and a plurality of first engagement tabs; and
a strainer member assembly having a circular cross-section, the strainer member assembly comprising:
a strainer member with a solid front surface having handle and a plurality of second engagement tabs interlocked with the first engagement tabs on the housing, the strainer member further comprising cylindrical strainer sidewalls defining a circular opening at a back of the strainer member and having an upper conduit aligned with the inlet port of the housing; and
a circular strainer disk coupled to the strainer member with a fastener and covering the circular opening at the back of the strainer member,

wherein the handle is an elongated handle that extends beyond the circular cross-section of the strainer member assembly and the plurality of second engagement tabs are located on the handle, wherein the second engagement tabs being positioned outside of the first engagement tabs and the handle is aligned with the inlet port when the second engagement tabs are interlocked with the first engagement tabs.

10. The vehicle galley of claim 9 , wherein the vehicle comprises an aircraft, a train, or a ship.

11. The vehicle galley of claim 9 , wherein the strainer member assembly further comprises a sealing member.

12. The vehicle galley of claim 11 , wherein the sealing member comprises a circular o-ring located within a corresponding groove in the cylindrical strainer sidewalls of the strainer member.

13. The vehicle galley of claim 9 , wherein the fastener comprises an attachment pin or a hinge mechanism.

14. A method of removing debris from a drain strainer assembly having a circular housing and a circular strainer member assembly, the method comprising:
rotating a handle of the strainer member assembly to disengage a first plurality of engagement tabs on the strainer member assembly from a second plurality of complementary engagement tabs on the housing;
removing the strainer member assembly from an opening in a front of the housing, the strainer member further comprising cylindrical strainer sidewalls defining a circular opening at a back of the strainer member and having an upper conduit aligned with the inlet port of the housing;
moving a strainer disk from the back of the strainer member assembly to reveal the circular opening at the back of the strainer member assembly;
discarding debris through the circular opening at the back of the strainer member assembly; and
inserting the strainer member assembly into the opening in the front of the housing and securing the strainer member assembly in the housing by rotating the handle of the strainer member assembly, wherein the handle is an elongated handle that extends beyond a circular cross-section of the strainer member assembly and securing the strainer assembly further comprising rotating the elongated handle until the first engagement tabs are engaged with the second engagement tabs and the elongated handle is aligned with an inlet port of the housing.

15. The method of claim 14 , further comprising washing and rinsing the strainer member assembly.

16. The method of claim 14 , wherein moving the strainer disk comprises: (a) rotating the strainer disk around an attachment pin, or (b) opening a hinge mechanism.
