[0020] For reference Figs. 1-2 As shown in the drawings, an outer cylinder assembly comprises a rear cylinder structure 1; the rear cylinder structure 1 is provided with a water inlet 2, and the inner surface 11 of the rear cylinder structure is provided with a condensing groove 3; the condensing groove 3 is communicated with the water inlet 2; the condensing water flows into the condensing groove 3 through the water inlet 2 to condense the to-be-condensed gas. The condensing groove 3 is a groove structure, so that the condensing water flows in the inner surface along the groove, i.e., the condensing groove 3, uniformly covers the inner surface of the rear cylinder, exchanges with the hot and humid air, prevents the condensing water from splashing, has high controllability of the flow path of the condensing water on the inner surface of the rear cylinder, and further improves the drying efficiency. The condensing water can be prevented from splashing when flowing on the inner surface of the rear cylinder; the present application has high controllability of the flow direction of the condensing water; and the drying efficiency can be further improved. The present application adopts the rear cylinder condensing and the new air duct condensing simultaneously when the washing and drying machine is drying. For the rear cylinder condensing part, the groove structure opposite to the flow guide rib structure is arranged on the inner surface of the rear cylinder (the flow guide rib protrudes from the inner surface 11 of the rear cylinder structure, and the groove structure is recessed from the inner surface 11 of the rear cylinder structure), so that the condensing water flows in the inner surface along the groove, uniformly covers the inner surface of the rear cylinder, exchanges with the hot and humid air, prevents the condensing water from splashing, and improves the drying efficiency.

[0021] The application also discloses some embodiments, wherein the rear cylinder structure 1 is further provided with a water outlet 4, and the condensing groove 3 extends from the water inlet 2 to the water outlet 4. The condensing water flows into the condensing groove 3 through the water inlet 2, and condenses the gas to be condensed in the condensing groove 3, and then flows out of the condensing groove 3 through the water outlet 4.

[0022] The application also discloses some embodiments, wherein the condensing groove 3 comprises a curved extension groove; and the condensing groove 3 extends from the water outlet 4 to the water outlet 4 without bending, so that the condensing water can stay on the inner surface of the rear cylinder for a certain period of time, and can be fully heat-exchanged with the gas to be condensed, thereby achieving better condensing effect.

[0023] The application also discloses some embodiments, wherein the condensing groove 3 is evenly arranged on the inner surface 11 of the rear cylinder structure, so that the condensing water is evenly distributed on the inner surface 11 of the rear cylinder structure, thereby achieving better condensing effect.

[0024] The application also discloses some embodiments, wherein the condensing groove 3 comprises an inlet groove 31, at least one branch groove and an outlet groove 32; the inlet groove 31 is communicated with the water inlet 2, the outlet groove 32 is communicated with the water outlet 4; and each branch groove is communicated with the inlet groove 31 and the outlet groove 32. The plurality of branch grooves are evenly distributed on the inner surface 11 of the rear cylinder structure, and when there are two branch grooves, the two branch grooves are located on the two sides of the rear cylinder bearing. After the condensing water flows down from the water inlet 2, the condensing water flows in the inlet groove 31, and then is branched into each branch groove; the fluid in each branch groove flows into the outlet groove 32, and finally flows out of the water outlet 4. For example, when there are two branch grooves, after the condensing water flows down from the water inlet 2, the condensing water flows in the inlet groove 31, and then is branched into the two branch grooves, thereby forming two water flows on the left and right sides of the inner surface; the two water flows flow to the outlet groove 32 and then are collected, and finally flow out of the water outlet 4. The branch grooves can also be one, three or more.

[0025] The application also discloses some embodiments, wherein the condensing groove 3 comprises straight grooves and curved grooves which are communicated with each other; and the straight grooves and the curved grooves are arranged at intervals, so that the water paths of the condensing groove 3 are evenly distributed on the inner surface 11 of the rear cylinder structure, thereby achieving better condensing effect.

[0026] The application also discloses some embodiments, wherein the water inlet 2 is arranged at the top of the rear cylinder structure 1, and the water outlet 4 is arranged at the bottom of the rear cylinder structure 1; the straight grooves are arranged obliquely, the straight grooves extend obliquely relative to the horizontal direction, and one end of the straight grooves downstream of the fluid extends obliquely downward relative to the horizontal direction, so that the water flow flows along the condensing groove 3 under the action of gravity. The application can make the condensing water flow along a fixed path after flowing down from the water inlet 2, and the condensing water does not enter the inner cylinder to repeatedly wet the clothes and reduce the drying efficiency, so that the hot and humid air passing through the wet clothes is primarily condensed on the inner surface of the rear cylinder.

[0027] The application further discloses some embodiments, wherein the linear groove is inclined downward by an angle of theta relative to the horizontal direction at one end downstream of the fluid; wherein 0 < theta < 5 degrees, so that the water flow can flow along the condensing groove 3 under the action of gravity, the flow rate of the condensed water is ensured to be not too fast, and the condensed water can fully play a condensing effect.

The size limitation of the inclined section and the arc-shaped section can ensure that the number of the condensing grooves 3 on the inner surface of the rear cylinder meets the requirements. If the size is too large, the number of the condensing grooves 3 will be reduced, the water distribution will be uneven, and the condensing effect will be unsatisfactory.

After the cycle, the condensing effect on the hot and humid air is greatly improved compared with the original single-air-duct single-condensing washing and drying machine.
