Abstract
A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter inlet and a filter outlet are positioned along a bottom portion of the filter housing, and filter media is positioned within the filter chamber to remove contaminants from water flowing through the filter media. A divider wall is positioned within the filter chamber to direct the flow of water through a flow aperture at a top portion of the filter chamber, such that the filter chamber remains filled with water during operation. As a result, the filter media remains completely submerged, thereby improving filtration performance, reducing pressure drop, and more evenly depleting the filter media.
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 comprising a sidewall extending along a longitudinal axis between a first end wall and a second end wall, the filter housing defining a filter chamber;
- a filter inlet;
- a filter outlet positioned proximate the second end wall of the filter housing;
- a filter medium positioned within the filter chamber, the filter medium operable to remove contaminants from water flowing through the filter medium;
- a divider wall positioned proximate the second end wall of the filter housing to prevent the flow of water from the filter chamber to the filter outlet;
- and
- a bypass channel defined by a top portion of the sidewall along the vertical direction through which water may flow from the filter chamber over the divider wall to the filter outlet.
A filter for a non-plumbed appliance, the filter defining a longitudinal direction and a radial direction, the filter comprising:
- a 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;
- a filter outlet positioned proximate the second end wall of the filter housing;
- a filter medium positioned within the filter chamber, the filter medium operable to remove contaminants from water flowing through the filter medium;
- a divider wall positioned proximate the second end wall of the filter housing, the divider wall defining a flow aperture at a periphery of the divider wall along the radial direction, such that water may flow from the filter chamber to the filter outlet only through the flow aperture.
