The washing barrel is configured to accommodate washing water. The washing barrel comprises a barrel body and a drainage channel being arranged on a side wall of the barrel body and configured to discharge washing water in the barrel body out of the barrel body during dehydrating. The drainage channel is provided with a water inlet communicated with an inside of the barrel body; and the barrel body is provided with a guiding part used to guide washing water in the barrel body into the water inlet during dehydrating. The present disclosure has the following beneficial effects: through setting the guiding part, the washing water is guided to the drainage channel and discharged through the drainage channel to realize rapid dehydration. ## Claims ### Claim 1 A washing barrel, being configured to accommodate washing water, comprising a barrel body, a drainage channel, being arranged on a side wall of the barrel body and configured to discharge washing water in the barrel body out of the barrel body during dehydrating, wherein the drainage channel is provided with a water inlet communicated with an inside of the barrel body; and the barrel body is provided with a guiding part used to guide washing water in the barrel body into the water inlet during dehydrating. ### Claim 2 (depends on 1) The washing barrel according to claim 1, wherein the guiding part is a variable diameter segment formed by increasing a radius of the side wall of the barrel body along a rotating direction of the barrel body during dehydrating; and the drainage channel is arranged on the variable diameter segment. ### Claim 3 (depends on 1, 2) The washing barrel according to claim 1 or 2, wherein the variable diameter section in a circumferential direction is formed by increasing the radius of at least a segment, at an axial direction, of the side wall of the barrel body along the rotation direction of the barrel body during dehydrating. ### Claim 4 (depends on 3) The washing barrel according to claim 3, wherein the barrel body is provided with at least one connecting segment in the circumferential direction; the connecting segment and the variable diameter segment are arranged at intervals, and two ends of the connecting segment are respectively connected with the variable diameter segment which is adjacent to the connecting segment to close the barrel body in the circumferential direction. ### Claim 5 (depends on 4) The washing barrel according to claim 4, wherein the barrel body is provided with variable diameter segments in the circumferential direction, and the variable diameter segments are uniformly distributed in the circumferential direction of the barrel body. ### Claim 6 (depends on 2) The washing barrel according to claim 2, wherein the drainage channel is arranged on an inner wall of the variable diameter segment, and the water inlet is arranged on the drainage channel. ### Claim 7 (depends on 6) The washing barrel according to claim 6, wherein the inner wall of the variable diameter segment is provided with a cover body with cavity, the water inlet is arranged on the cover body and faces towards the rotating direction of the barrel body during dehydrating, and the cover body forms the drainage channel together with the inner wall of the variable diameter segment in the form of encirclement; or, the cover body forms the drainage channel together with the inner wall of the variable diameter segment and the inner wall of the connecting segment in the form of encirclement; or, the drainage channel is a drainage pipeline for allowing the washing water to flow through; the water inlet is arranged on the drainage pipeline and faces towards the rotating direction of the barrel body during dehydrating. ### Claim 8 (depends on 5) The washing barrel according to claim 5, wherein an outer wall of the variable diameter segment is provided with a cover body having a cavity; the cover body forms the drainage channel together with the outer wall of the variable diameter segment and/or an outer wall of the connecting segment in the form of encirclement; the water inlet is arranged on variable diameter segment or the connecting segment. ### Claim 9 (depends on 5) The washing barrel according to claim 5, wherein the drainage channel is a drainage pipeline for allowing the washing water to flow through; the drainage channel is arranged on the outer wall of the variable diameter segment; the variable diameter segment or the connecting segment is provided with a dehydrating opening, and the water inlet of the drainage channel is connected with the dehydrating opening. ### Claim 10 (depends on 1) A washing machine provided with the washing barrel according to claim 1. ### Claim 11 (depends on 3) The washing barrel according to claim 3, wherein the radius of the side wall of the barrel body is synchronously increased from top to bottom along the rotating direction of the barrel body to form the variable diameter segment in the circumferential direction; or, the radius of at least a part, arranged between an upper edge and a lower edge of the water inlet, of the side wall of the barrel body increases along the rotating direction of the barrel body during dehydrating, forming the variable diameter segment. ### Claim 12 (depends on 4) The washing barrel according to claim 4, wherein one variable diameter segment and one connecting segment are provided, two ends of the one connecting segment are respectively connected with two ends of the one variable diameter segment, to close the circumference of the barrel body; or, variable diameter segments and connecting segments are provided, the connecting segments and the variable diameter segments are arranged at intervals; two ends of each of the connecting segments are respectively connected with end parts of two variable diameter segments connected with the connecting segment, to close the circumference of the barrel body. ### Claim 13 (depends on 3) The washing barrel according to claim 3, wherein the drainage channel is arranged on an inner wall of the variable diameter segment, and the water inlet is arranged on the drainage channel. ### Claim 14 (depends on 4) The washing barrel according to claim 4, wherein the drainage channel is arranged on an inner wall of the variable diameter segment, and the water inlet is arranged on the drainage channel. ### Claim 15 (depends on 5) The washing barrel according to claim 5, wherein the drainage channel is arranged on an inner wall of the variable diameter segment, and the water inlet is arranged on the drainage channel. ### Claim 16 (depends on 6) The washing barrel according to claim 6, wherein the drainage channel is arranged at a part with the biggest radius of the variable diameter segment.
