The central depression is deeper than side support ledges relative to the top edge of the rim. At least a portion of the central depression extends under at least a portion of each of the side support ledges. ## Claims ### Claim 1 An appliance drain pan comprising: a continuous upturned rim around an outer edge of the drain pan, the rim having a top edge; horizontal left and right side support ledges enclosed by the rim; a horizontal rear ledge and a horizontal front ledge; and a central depression between the horizontal left and right side support ledges, the central depression being deeper than the side support ledges relative to the top edge of the rim, at least a portion of the central depression extending under at least a portion of each of the side support ledges wherein the central depression is between and deeper than the rear and front ledges; wherein the central depression comprises a rear sloped wall adjacent the rear ledge, a front sloped wall adjacent the front ledge, and a horizontal floor, at least part of the horizontal floor being between the rear and front sloped walls; wherein the rear sloped wall comprises a vertical wall portion adjacent the rear ledge; wherein the front sloped wall comprises a vertical wall portion adjacent the front ledge; wherein a portion of the horizontal floor extends to the vertical wall portion of the rear sloped wall; and wherein a portion of the horizontal floor extends to the vertical wall portion of the front sloped wall. ### Claim 2 (depends on 1) The drain pan of claim 1, wherein the rear, front, and side ledges are unitary. ### Claim 3 (depends on 1) The drain pan of claim 1, wherein each side support ledge comprises an elongated beam removably positionable on the rear and front ledges with one end of each side support ledge sitting on the rear ledge and an opposing end of each side support ledge sitting on the front ledge, each side support ledge positioned over an opposing end of the central depression. ### Claim 4 (depends on 1) The drain pan of claim 1, wherein one or more drain holes are defined in each side support ledge, each drain hole being positioned over the central depression. ### Claim 5 (depends on 1) The drain pan of claim 1, further comprising left and right support pillars projecting upward from the central depression, each support pillar contacting an underside of a corresponding side support ledge to support the corresponding side support ledge. ### Claim 6 (depends on 1) The drain pan of claim 1, wherein a drain hole is defined in the central depression. ### Claim 7 A method of installing an appliance, the appliance comprising a left rear leg, a right rear leg, a left front leg, and a right front leg, the method comprising: (a) cutting and/or forming an installation hole in a floor in a location where the appliance is to be installed; (b) obtaining an appliance drain pan, the drain pan comprising: an upturned rim around an outer edge of the drain pan, the rim having a top edge; horizontal left and right side support ledges; and a central depression between the horizontal left and right side support ledges, the central depression being deeper than the side support ledges relative to the top edge of the rim; (c) positioning the drain pan such that the central depression sits down in the installation hole; and (d) sliding or lifting the appliance into position on top of the drain pan along the side support ledges. ### Claim 8 (depends on 7) The method of claim 7, wherein at least a portion of the central depression extends under at least a portion of each of the side support ledges. ### Claim 9 (depends on 7) The method of claim 7, wherein the drain pan further comprises a horizontal rear ledge and a horizontal front ledge; and wherein the central depression is between and deeper than the rear and front ledges. ### Claim 10 (depends on 9) The method of claim 9, wherein the rear, front, and side support ledges are unitary. ### Claim 11 (depends on 9) The method of claim 9, wherein each side support ledge comprises an elongated beam removably positionable on the rear and front ledges with one end of each side support ledge sitting on the rear ledge and an opposing end of each side support ledge sitting on the front ledge, each side support ledge positioned over an opposing end of the central depression. ### Claim 12 (depends on 9) The method of claim 9, wherein the central depression comprises a rear sloped wall adjacent the rear ledge, a front sloped wall adjacent the front ledge, and a horizontal floor, at least part of the horizontal floor being between the rear and front sloped walls. ### Claim 13 (depends on 9) The method of claim 9, wherein the rear sloped wall comprises a vertical wall portion adjacent the rear ledge; wherein the front sloped wall comprises a vertical wall portion adjacent the front ledge; wherein a portion of the horizontal floor extends to the vertical wall portion of the rear sloped wall; wherein a portion of the horizontal floor extends to the vertical wall portion of the front sloped wall; and wherein positioning the drain pan further comprises positioning the drain pan such that the vertical wall portion adjacent the rear ledge abuts the rear edge of the installation hole and such that the vertical wall portion adjacent the front ledge abuts the front edge of the installation hole. ### Claim 14 (depends on 7) The method of claim 7, wherein one or more drain holes are defined in each side support ledge, each drain hole being positioned over the central depression. ### Claim 15 (depends on 7) The method of claim 7, further comprising left and right support pillars projecting upward from the central depression, each support pillar contacting an underside of a corresponding side support ledge to support the corresponding side support ledge. ### Claim 16 (depends on 7) The method of claim 7, wherein a drain hole is defined in the central depression.
