Abstract
A downspout drain filter includes a housing and a filter media. The housing defines an internal cavity, an inlet to the internal cavity along a top of the housing, and an outlet from the internal cavity along a bottom of the housing. The filter media is disposed within the internal cavity. The filter media divides the internal cavity into an upper chamber and a lower chamber. The filter media is configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity. The filter media is permeable such that the fluid flows from the upper chamber to the lower chamber.
Claims14
A downspout drain filter comprising:
- a housing defining (i) an internal cavity, (ii) an inlet to the internal cavity along a top of the housing, and (iii) an outlet from the internal cavity along a bottom of the housing, wherein the housing includes (a) front and back panels that are disposed between the top and bottom of the housing, (b) first and second side panels extending between the front and back panels, and (c) first and second sloped surfaces extending between the back panel and the first and second side panels, respectively, wherein the first and second sloped surfaces extend into the internal cavity such that the internal cavity tapers in the direction that extends from the top to the bottom of the housing along the first and second sloped surfaces;
- and
- a filter plate (i) disposed within the internal cavity, (ii) dividing the internal cavity into an upper chamber and a lower chamber, (iii) configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity, (iv) permeable such that the fluid flows from the upper chamber to the lower chamber, and (v) having a removable central portion that provides access to the lower chamber from the upper chamber when removed.
A downspout drain filter comprising:
- a housing defining (i) an internal cavity, (ii) an inlet to the internal cavity along a top of the housing, and (iii) an outlet from the internal cavity along a bottom of the housing, wherein the housing includes (a) a back panel disposed between the top and bottom of the housing, (b) first and second side panels extending between the back panel and a front panel, and (c) first and second sloped surfaces extending between the back panel and the first and second side panels, respectively, wherein the first and second sloped surfaces extend into the internal cavity such that the internal cavity tapers in the direction that extends from the top to the bottom of the housing along the first and second sloped surfaces;
- and
- a filter media (i) disposed within the internal cavity, (ii) dividing the internal cavity into an upper chamber and a lower chamber, and (iii) configured to trap debris in the upper chamber from fluid flowing downward through the internal cavity, and (iv) permeable such that the fluid flows from the upper chamber to the lower chamber, wherein the housing further defines an overflow opening along the top of the housing, and wherein the overflow opening is configured to direct the fluid out of the internal cavity in response to (a) the filter media becoming clogged and (b) the fluid filling the upper chamber.
