When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the utility model. Rather, they are merely examples of apparatus and methods consistent with aspects of the utility model as detailed in the accompanying claims.

The present embodiment will be described in detail below with reference to the attached drawings, and the following embodiments and examples may be combined with each other without conflict.

According to an exemplary embodiment, as shown in fig. 1 to 4, the present embodiment proposes a rear drum 100 for a wall-mounted laundry treating apparatus. The wall-mounted laundry treating apparatus of the present embodiment may have only a washing function, and may also have both a washing function and a drying function. The rear drum 100 of the present embodiment includes a drum body 1, and the drum body 1 serves to accommodate an inner drum 200 of a wall-mounted laundry treating apparatus and to accommodate wash water. The cylinder 1 comprises an inner side wall 11, and a water discharge cavity 13 is arranged at the bottom of the inner side wall 11. Illustratively, the drain cavity 13 is a convex hull formed by the bottom of the inner side wall 11 protruding to the outside of the cylinder 1, the bottom wall of the drain cavity 13 is provided with a drain outlet 131, and water in the cylinder 1 is collected in the drain cavity 13 and then drained out of the cylinder 1 through the drain outlet 131. The rear barrel 100 further comprises two diversion structures 3, wherein the two diversion structures 3 are arranged on the inner side wall 11 and are positioned on two opposite sides of the drainage cavity 13, so that water drops positioned on two sides of the drainage cavity 13 are collected and guided into the drainage cavity 13. In a preferred embodiment, the two flow guiding structures 3 are symmetrically arranged about the drain opening 131. The diversion structure 3 includes a diversion protrusion 31, the diversion protrusion 31 is provided with a plurality of diversion channels 32, the plurality of diversion channels 32 are arranged along the width direction of the inner side wall 11, and each diversion channel 32 extends from the drainage cavity 13 along the circumferential direction of the inner side wall 11.

In some embodiments, as shown in fig. 1 and 3, the water guide passage 32 extends in the circumferential direction of the inner sidewall 11 to the same height as the axial center of the rear cylinder 100. This is because when the inner tube 200 is dehydrated, the water droplets thrown out from the water holes of the inner tube 200 adhere to the inner wall 11 due to the centrifugal force, the water droplets located higher than the axis of the inner wall 11 drop due to the gravity thereof being greater than the surface tension of the water droplets, and the water droplets located lower than the axis of the inner wall 11 are not easy to flow along the inner wall 11 due to the gravity thereof being less than or equal to the surface tension of the water droplets. Therefore, by extending the water guiding protrusion 31 to the height of the axis of the rear cylinder 100, the water droplets thrown out by the inner cylinder 200 directly fall on the water guiding protrusion 31, and the water droplets thrown below the axis height are better guided into the drainage chamber 13 by the guiding action of the water guiding protrusion 31.

In some embodiments, as shown in fig. 1 and 3, the water guiding protrusion 31 includes a first end and a second end along the circumferential direction of the inner sidewall 11, the first end being adjacent to the water discharge chamber 13, and the width of the water guiding protrusion 31 is tapered from the second end to the first end, thereby facilitating guiding the water flow in the plurality of water guiding channels 32 into the water discharge chamber 13. In a preferred embodiment, the first end is disposed opposite the drain opening 131, and further, the drain opening 131 is located on a midline of the first end. Illustratively, the width of the first end is 1/3 to 2/3 of the width of the second end. In one specific example, the width of the second end is comparable to the depth of the rear barrel 100, and the width of the first end is half the depth of the rear barrel 100.

In an example, as shown in fig. 1 and 3, the rear barrel 100 includes a rear barrel rear wall 12, the water discharge port 131 is provided at a position of the water discharge chamber 13 near the rear barrel rear wall 12, and the water guide protrusion 31 is inclined from the second end toward a direction near the rear barrel 100 rear wall so as to guide the water flow in the water guide channel 32 directly to the water discharge port 131, thereby improving the water discharge efficiency.

In some embodiments, as shown in fig. 2, the water guiding protrusion 31 includes a plurality of prismatic ribs 311, the plurality of prismatic ribs 311 extend along the circumferential direction of the inner sidewall 11, and the water guiding channel 32 is formed between two adjacent prismatic ribs 311, and the prismatic ribs 311 can effectively divide the water droplets, so that the water droplets are divided to two sides of the prismatic ribs 311. The distance between adjacent ribs 311 is 20mm to 40mm, and/or the height of the ribs 311 with respect to the inner sidewall 11 is 3mm to 5mm, so that the water droplets in the water guide channel 32 smoothly flow down. Illustratively, the inner parts of the two side-direction prismatic ribs 311 of the prismatic ribs 311 are recessed to form a water retaining cambered surface 33, and the water retaining cambered surfaces 33 of two adjacent prismatic ribs 311 are connected to form a water guiding channel 32, so that the inner wall surface of the water guiding channel 32 is a concave surface, and the split water drops are collected into the water guiding channel 32 and then flow into the drainage cavity 13 along the inner wall surface of the water guiding channel 32.

The water guiding protrusion 31 of the present embodiment may be disposed independently of the inner sidewall 11, and fixed to the inner sidewall 11 by means of clamping, inserting, connecting or bonding, etc., and the water guiding protrusion 31 may be integrally formed with the inner sidewall 11. The plurality of ribs 311 of the water guiding protrusion 31 may be integrally provided or may be separately and independently provided. In other possible embodiments, as shown in fig. 4, the water guiding protrusion 31 includes a plurality of independent ribs extending in the circumferential direction of the inner sidewall 11, and the water guiding channel 32 is formed between the adjacent ribs.

In some embodiments, the water diversion channel 32 includes a wavy channel extending along the circumferential direction of the inner sidewall 11, and the water diversion channel 32 may extend along the circumferential direction of the inner sidewall 11 in a wavy structure throughout the channel, or may extend along the circumferential direction of the inner sidewall 11 in a wavy structure throughout a part of the channel of the water diversion channel 32. The wave-shaped flow channel can increase the acceleration of the movement of the water drops in the water guide flow channel 32, so that the flow speed of the movement of the water drops in the water guide flow channel 32 is improved, and the water flow collection efficiency is improved.

According to an exemplary embodiment, the present embodiment provides an outer cylinder, which includes a front cylinder 300 and any one of the rear cylinders 100 provided in the foregoing embodiments, where the front cylinder 300 is disposed at the front opening of the rear cylinder 100, and a containing cavity formed by enclosing the front cylinder 300 and the rear cylinder 100 is used for containing the inner cylinder 200, and the front cylinder 300 can play a role in supporting and limiting the inner cylinder 200, so as to ensure the reliability of assembly between the inner cylinder 200 and the rear cylinder 100 and prevent the inner cylinder 200 from being separated from the containing cavity. The front drum 300 is provided with a laundry putting opening 301, and a user puts laundry into the inner drum 200 through the laundry putting opening 301.

According to an exemplary embodiment, as shown in fig. 5 and 6, the present embodiment proposes a wall-mounted laundry treating apparatus comprising: the inner cylinder 200 and any outer cylinder proposed in the above embodiments, the inner cylinder 200 is rotatably disposed in the outer cylinder. The drum wall of the inner drum 200 is provided with a plurality of water passing holes, and water in the outer drum can enter the inner drum 200 through the water passing holes in the washing and rinsing processes of clothes, and meanwhile, water in the inner drum 200 can also enter the outer drum through the water passing holes.
