The cabinet may define an internal volume. The drum may be mounted within the cabinet. The drum may define a drying chamber, a dryer opening, an air inlet, and a fluid port. The drying chamber may extend from a front end to a rear end. The dryer opening may be defined at the front end to permit articles therethrough to the drying chamber. The air inlet may be defined at the rear end to permit air therethrough to the drying chamber. The fluid port may be spaced apart from the air inlet. The fluid port may extend from the drying chamber to the internal volume. The supply duct may extend within the cabinet to the drum upstream from the air inlet. ## Claims ### Claim 1 A dryer appliance comprising: a cabinet defining an internal volume; a drum mounted within the cabinet, the drum defining a drying chamber extending from a front end to a rear end, a dryer opening at the front end to permit articles therethrough to the drying chamber, an air inlet at the rear end to permit air therethrough to the drying chamber, and a fluid port spaced apart from the air inlet, the fluid port extending from the drying chamber to the internal volume; and a supply duct extending within the cabinet to the drum upstream from the air inlet. ### Claim 2 (depends on 1) The dryer appliance of claim 1, further comprising a plug received within the fluid port to restrict air therethrough. ### Claim 3 (depends on 2) The dryer appliance of claim 2, wherein the plug has a melting temperature between 120° Celsius and 300° Celsius. ### Claim 4 (depends on 1) The dryer appliance of claim 1, wherein the fluid port is first port, and wherein the drum further defines a second port spaced apart from the first port and the air inlet, the second port extending from the drying chamber to the internal volume. ### Claim 5 (depends on 4) The dryer appliance of claim 4, wherein the first port is disposed above the second port. ### Claim 6 (depends on 4) The dryer appliance of claim 4, further comprising: a first plug received within the first port to restrict air therethrough; and a second plug received within the second port to restrict air therethrough. ### Claim 7 (depends on 1) The dryer appliance of claim 1, wherein the cabinet comprises a rear panel, and wherein the fluid port is spaced apart from the rear panel by an air gap greater than or equal to ten millimeters. ### Claim 8 (depends on 7) The dryer appliance of claim 7, wherein the rear panel defines a cabinet opening in fluid communication with the internal volume. ### Claim 9 (depends on 1) The dryer appliance of claim 1, wherein the drum comprises a rear support wall at the rear end, and wherein the fluid port is defined through the rear support wall. ### Claim 10 (depends on 1) The dryer appliance of claim 1, further comprising: a ventilation assembly attached to the drum, the ventilation assembly comprising a conduit defining an exhaust passage in fluid communication with the drying chamber, the conduit extending from an inlet at the drying chamber to an outlet defined through the cabinet. ### Claim 11 A dryer appliance comprising: a cabinet defining an internal volume; a drum mounted within the cabinet, the drum defining a drying chamber extending from a front end to a rear end, a dryer opening at the front end to permit articles therethrough to the drying chamber, an air inlet at the rear end to permit air therethrough to the drying chamber, and a first port spaced apart from the air inlet, the first port extending from the drying chamber to the internal volume proximal from the rear end, and a second port spaced apart from the first port and the air inlet, the second port extending from the drying chamber to the internal volume in parallel with the first port; and a supply duct extending within the cabinet to the drum upstream from the air inlet. ### Claim 12 (depends on 11) The dryer appliance of claim 11, further comprising: a first plug received within the first port to restrict air therethrough; and a second plug received within the second port to restrict air therethrough. ### Claim 13 (depends on 12) The dryer appliance of claim 12, wherein the first and second plugs have a melting temperature between 120° Celsius and 300° Celsius. ### Claim 14 (depends on 11) The dryer appliance of claim 11, wherein the first port is disposed above the second port. ### Claim 15 (depends on 11) The dryer appliance of claim 11, wherein the cabinet comprises a rear panel, and wherein the first fluid port is spaced apart from the rear panel by an air gap greater than or equal to ten millimeters. ### Claim 16 (depends on 15) The dryer appliance of claim 15, wherein the rear panel defines a cabinet opening in fluid communication with the internal volume. ### Claim 17 (depends on 11) The dryer appliance of claim 11, wherein the drum comprises a rear support wall at the rear end, and wherein the first port and the second port are defined through the rear support wall. ### Claim 18 (depends on 11) The dryer appliance of claim 11, a ventilation assembly attached to the drum, the ventilation assembly comprising a conduit defining an exhaust passage in fluid communication with the drying chamber, the conduit extending from an inlet at the drying chamber to an outlet defined through the cabinet.
