Water filter audible position indicator
A water filter assembly having a manifold with a rotatable cylinder in which a filter cartridge is removably received is provided. The filter assembly has a noise generator adjacent to the rotatable cylinder of the manifold. When the filter cartridge with the rotatable cylinder is rotated between an installed position and an uninstalled position, the noise generator creates an audible noise. The noise may indicate, for example, that the filter cartridge may be removed from the manifold.
1. A water filter assembly, comprising:
a manifold that comprises
a housing that defines an inlet for receiving unfiltered water into the water filter assembly and an outlet for directing filtered water out of the water filter assembly
a cylinder rotatably received within the housing and in fluid communication with the inlet and outlet, the cylinder defining a port, the cylinder rotatable within the housing between an installed position and an uninstalled position;
an actuator projecting from the cylinder;
a filter cartridge removably received into the port, the filter cartridge comprising a filter housing and a filtering media positioned therein for filtering a flow of water through the water filter assembly, the filter cartridge rotatable with the cylinder between the installed position and the uninstalled position; and
a noise generator positioned adjacent to the cylinder such that the actuator engages the noise generator and creates an audible noise as the cylinder is rotated between the uninstalled position and the installed position.
2. A water filter assembly as in claim 1 , wherein the filter cartridge further comprises a boss configured for receipt into the port.
3. A water filter assembly as in claim 1 , wherein the noise generator comprises a resilient member such that the actuator bends the resilient member to create the audible noise as the cylinder is rotated between the uninstalled position and the installed position.
4. A water filter assembly as in claim 3 , wherein the resilient member is a leaf spring, and the resilient member has a free end and a mounted end.
5. A water filter assembly as in claim 3 , wherein the noise generator further comprises a dimple having a deformed condition and an undeformed condition, and the dimple is biased towards the undeformed condition such that the dimple generates the audible noise as the dimple changes from the undeformed condition to the deformed condition as the resilient member is bent.
6. A water filter assembly as in claim 1 , wherein the water filter assembly further comprises a retaining clip having a pair of arms within which the filter cartridge is received when rotated into the installed position.
7. A water filter assembly as in claim 6 , wherein the filter cartridge defines a length and the pair of arms of the retaining clip is disposed greater than half of the length of the filter cartridge from the manifold.
8. A water filter assembly as in claim 1 , wherein the filter cartridge comprises
a boss extending from an end of the filter cartridge, and
a locking tab projecting from the boss;
wherein the housing of the manifold defines an opening, and the opening is sufficiently large to receive the locking tab of the filter cartridge therethough in the uninstalled position.
9. A water filter assembly as in claim 8 , wherein the housing of the manifold and the cylinder define an arcuate slot therebetween, and the locking tab of the filter cartridge is received in the slot in the installed position.
10. A water filter assembly as in claim 1 , wherein the housing of the manifold defines an opening for the actuator to project therethrough.
11. A water filter assembly comprising:
a base;
a manifold mounted to the base, the manifold comprising
a housing that defines an inlet for receiving unfiltered water into the water filter assembly and an outlet for directing filtered water out of the water filter assembly;
a cylinder rotatably received within the housing and in fluid communication with the inlet and outlet, the cylinder defining a port, the cylinder rotatable within the housing between an installed position and an uninstalled position;
an actuator projecting from the cylinder;
a filter cartridge comprising a boss, a filter housing, and a filtering media positioned therein for filtering a flow of water through the water filter assembly, the filter cartridge rotatable with the cylinder between the installed position and the uninstalled position, the boss selectively received in the cylinder of the manifold in the uninstalled position, the boss of the filter cartridge locked in the cylinder in the installed position;
a retaining clip mounted to the base, the retaining clip having a pair of arms protruding away from the base for receiving the filter cartridge therebetween in the installed position; and
a noise generator positioned adjacent to the cylinder such that the actuator engages the noise generator and creates an audible noise as the cylinder is rotated between the uninstalled position and the installed position.
12. A water filter assembly as in claim 11 , wherein the base comprises a middle surface and a pair of side walls, the surface disposed between the pair of side walls, the pair of side walls protruding away from the middle surface such that the surface and the pair of sidewalls define a filter cartridge receiving space, and the filter cartridge is at least partially received in the receiving space in the installed position.
13. A water filter assembly as in claim 12 , wherein each of the pair of side walls of the base is orthogonal to the middle surface of the base.
14. A water filter assembly as in claim 12 , wherein each of the arms of the retaining clip is attached to a respective one of the pair of side walls of the base.
15. A water filter assembly as in claim 11 , wherein the retaining clip is a continuous member and has a middle portion attached to the base, and the continuous member comprises each of the pair of arms.
16. A water filter assembly as in claim 11 , wherein each of the pair of arms of the retaining clip defines an arcuate section curved inward toward the filter cartridge in the installed position.
17. A water filter assembly as in claim 16 , wherein:
each of the pair of arms of the retaining clip comprises a free end and a guide section; and
the guide section is defined between the arcuate section and the free end, and the guide section protrudes away from the filter cartridge in the installed position to guide the filter cartridge between the pair of arms.
18. A water filter assembly as in claim 11 , wherein the housing of the manifold and the cylinder define an arcuate slot therebetween, and wherein the filter cartridge includes a locking tab received in the slot when in the installed position to lock the boss of the filter cartridge in the cylinder of the manifold when in the installed position.
19. A water filter assembly as in claim 18 , wherein the actuator has an attached end and a free end, and the attached end is attached to the cylinder of the manifold, and the free end protrudes radially away from the cylinder of the manifold and engages the noise generator as the cylinder is rotated between the uninstalled position and the installed position.
20. A water filter assembly as in claim 19 , wherein the actuator has a cylindrical shape.
