Abstract
A drain guard is configured to block debris from entering a drain line of an HVAC unit. The guard includes a hollow body having a front side, a first side, a second side, and a back side defining an internal volume. A lip extending outward from a ridge formed at the convergence of the front side and the back side subsequently extends downward and parallel to the back side. The gap made between the back side and the lip may act as a receiving section for a sidewall of a drain pan so that the device may be stabilized. For further stabilization, cutouts are positioned in the back side and lip of the device so that a drain pipe connected to the drain pan may be seamlessly positioned adjacent the device.
Claims17
A cover device for impeding debris approaching a drain, comprising:
- a body having an internal volume defined by a front side, a first side, a second side, and a back side;
- a ridge defined by the convergence of the front side and the back side;
- a lip extending outward from the ridge, the lip further extending substantially parallel with the back side;
- and
- wherein at least one of the back side and the lip is configured to receive at least a portion of a conduit such that the body seamlessly rests on the conduit while water drains through the body and the conduit while debris approaching the conduit is impeded.
An HVAC unit drainage system for filtering condensate, comprising:
- an HVAC unit having a condenser;
- a drainage pan positioned below at least a portion of the condenser;
- and
- a cover device for impeding debris approaching a drain pipe of the drainage pan, the cover device seamlessly positioned adjacent the drain pipe entrance and the drainage pan, the cover device comprising:
- a body having an internal volume defined by a front side, a first side, a second side, and a back side;
- a ridge defined by the convergence of the front side and the back side;
- and
- a lip extending outward from the ridge, the lip further extending substantially parallel with the back side;
- and
- wherein the cover device simultaneously allows flow of condensate into the drain through the cover device and impedes debris approaching the drain.
A drain guard for blocking debris from entering a drain pipe of a drainage pan, comprising:
- a hollow elongated body, the hollow body comprising an unperforated back side, at least one perforated side defining an internal volume and affixed to the back side, and an open bottom;
- a ridge defined by the convergence of the back side and at least one of the at least two perforated sides, the ridge defining an apex of the guard;
- a lip extending outward from the ridge, the lip further extending substantially parallel with the back side and forming a gap with the back side for retention of a sidewall of a drainage pan between the lip and the back side, the lip extending the length of the unperforated back side;
- a plurality of cutouts positioned within the lip and the back side for receiving the drain pipe, the plurality of cutouts increasing the stability of the drain guard when the drain guard is placed in a drainage pan;
- and
- wherein the body of the cover device is configured to extend into the drainage pan and away from an entrance of the drain pipe so as to create a volume of space to decrease the likelihood for debris to block the flow of condensate into the drain pipe.
