Abstract
A filter for a non-plumbed appliance is provided. The filter includes a filter housing having a sidewall extending along a longitudinal direction between a first end wall and a second end wall. A flow distribution channel is also defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the flow aperture and the first end wall of the filter housing. The flow distribution channel equalizes the pressure gradient on the outer surface of the filter media, resulting in an improved flow pattern, increased clogging resistance, and improved filter performance capacity.
Claims20
A non-plumbed appliance defining a vertical direction, a lateral direction, and a transverse direction, the non-plumbed appliance comprising:
- a water tank defining a storage volume;
- a pump in fluid communication with the storage volume for actively flowing water from the water tank;
- and
- a filter disposed within the storage volume such that water is flowable from the storage volume through the filter to the pump, the filter comprising:
- a filter housing defining a longitudinal direction and a radial direction, the filter housing comprising a sidewall extending along the longitudinal direction between a first end wall and a second end wall, the filter housing defining a filter chamber;
- a filter inlet positioned proximate the first end wall of the filter housing;
- a filter outlet positioned proximate the second end wall of the filter housing;
- a filter medium positioned within the filter chamber, the filter medium defining a first end, a second end separated from the first end along the longitudinal direction, and an interior passage, the filter medium being operable to remove contaminants from water flowing through the filter medium;
- and
- a flow distribution channel defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the first end wall and the second end wall of the filter housing.

- a flow partition positioned at the second end wall of filter housing to prevent the flow of water from the filter chamber to the filter outlet;
- a flow aperture defined at a periphery of the flow partition along the radial direction, the flow aperture enabling water to flow from the filter chamber around the flow partition to the filter outlet;
- and
- a flow distribution channel defined by the sidewall of the filter housing, the flow distribution channel extending outwardly from the sidewall along the radial direction and along the longitudinal direction between the flow aperture and the first end wall of the filter housing.
