The plurality of turbulence columns 51 may have the same shape, or may have different shapes, such as a cylindrical shape, a spherical shape, a rectangular shape, a conical shape, or a fan shape, for example. Because the condensed water generates sputtering when flowing on the surface of the spoiler column 51, the sharp-angled structure on the spoiler column 51 can easily cause the condensed water to enter the inner barrel 11 to wet the clothes, and therefore, referring to fig. 3 and 4, the spoiler column 51 is spherical in the embodiment of the application, the spoiler column 51 has no sharp-angled structure, and the problem of sputtering generated when the condensed water flows on the surface of the spoiler column 51 can be reduced.

Of course, the above-mentioned intervals between the spoiler strips 52 may be the same, or may be different, that is, the plurality of spoiler strips 52 are uniformly spaced, or are non-uniformly spaced (e.g., randomly spaced).
It should be noted that the material used for the outer cylinder 12 may be plastic, and when the outer cylinder 12 is injection molded, the two flow disturbing structures 5 may be integrally formed with the outer cylinder 12, which is more convenient to manufacture.
In some embodiments, the flow disturbing structure 5 is laid on the whole inner surface of the back plate 121 of the outer cylinder 12, so that the heat exchange area between the condensed water and the gas is large, and the condensation effect is good.
In other embodiments, the turbulence structure 5 is laid on a part of the inner surface of the back plate 121 of the outer cylinder 12, and if the turbulence structure 5 is only laid on a part of the inner surface of the back plate 121 of the outer cylinder 12 between the condensed water inlet 122 and the center line of the outer cylinder 12, the condensed water flows faster on the lower half portion of the back plate 121 of the outer cylinder 12.
The back plate 121 of the outer tub 12 is inclined inward from the outer edge to the center in the radial direction, and the design of the drum washing machine is more compact, so that the volume of the drum washing machine is smaller. The included angle α between the partial wall surface above the central line of the outer cylinder 12 and the vertical surface is larger than the included angle β between the partial wall surface below the central line of the outer cylinder 12 and the vertical surface, and the partial inclined wall surface between the water inlet and the central line of the outer cylinder 12 on the outer cylinder 12 can guide the condensed water to flow along the surface of the condensed water, so that the flow area of the condensed water is further increased, and the problems of splashing of the condensed water or separation of the condensed water from the inner surface of the back plate 121 of the outer cylinder 12 are reduced.
Based on the above embodiment, referring to fig. 2, if the included angle α between the vertical plane and the partial wall surface above the center line on the outer cylinder 12 is too small, the flow area of the condensed water is small; if the included angle α between the vertical plane and the wall surface of the outer tub 12 above the center line is too large, the size of the drum washing machine along the axial direction of the outer tub 12 is large. Therefore, in the embodiment of the present application, the included angle β between the vertical surface and the partial wall surface of the outer cylinder 12 below the central line ranges from 3 ° to 20 °, the included angle α between the vertical surface and the partial wall surface of the outer cylinder 12 above the central line ranges from 5 ° to 25 °, and the flow area of the condensed water is large under the condition that the volume of the drum washing machine is small.
Referring to fig. 2, the height H of the turbulence structure 5 cannot be too high, otherwise, water is easily splashed into the inner drum 11 to wet the clothes; the height H of the above-mentioned turbulent flow structure 5 cannot be too low, otherwise the water guide effect is poor, the heat exchange area is small, and the condensation effect of the air flow in the outer cylinder 12 is poor. Therefore, in the drum washing machine of the embodiment of the present application, the distance L between the back plate 121 of the outer drum 12 and the back plate 121 of the inner drum 11 is 3-50 mm, and the height H of the turbulent flow structure 5 is 1-25 mm, so that the water flow is prevented from splashing into the inner drum 11 to wet the clothes under the condition of ensuring a good condensation effect.
In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
