Detailed Description

First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the inner cartridge assembly of the present invention is described in connection with a drum washing machine, this is not intended to be limiting and other devices having the use requirements of "parts and dirty water isolation" may be configured with the inner cartridge assembly of the present invention.

Next, it should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "inside", "outside", and the like are based on the direction or positional relationship shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or member must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.

Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The existing drum washing machine comprises an inner drum, an inner drum rear flange and a tripod, wherein the inner drum rear flange is connected to one end of the inner drum and used for sealing the inner drum, and the tripod is connected to one side, deviating from the inner drum, of the inner drum rear flange. Water holes are arranged on the side wall of the inner barrel, the rear flange of the inner barrel and the triangular support, and the washed water flows out of the outer side of the inner barrel from the water holes. It can be understood that since the washed water flows through the region between the rear flange of the inner tub and the tripod, some of the contaminants in the washed water must remain on the tripod.

In addition, the washing machine comprises an outer barrel, and because the outer barrel of the washing machine is sleeved outside the inner barrel, the washed water flowing out of the inner barrel can flow below the tripod and enter the outer barrel, so that the washed water can pollute the bottom of the tripod. In the actual life, the user is difficult to clear up the pollutant that remains on the tripod, and in the past, not only pollute and wait to wash the clothing, also easily appear the peculiar smell because of the long-term residue of dirt, seriously influence customer's experience moreover.

In summary, in order to reduce or block the contact of the washed water with the tripod, it is necessary to separate the washed water from the tripod. Thus, the concept of the present application is: the water passing port can be only arranged on the side wall of the inner cylinder above the tripod so as to prevent the washed water from flowing through the tripod; the bottom of the tripod may be capped to isolate the bottom of the tripod from contact with the washed water.

The technical scheme of the inner drum assembly and the washing machine of the present application is described below with reference to the above.

FIG. 1 is a perspective view of an inner barrel assembly provided in accordance with an exemplary embodiment; FIG. 2 is a top view of an inner barrel assembly provided in accordance with an exemplary embodiment; FIG. 3 is a cross-sectional view of an inner barrel assembly provided in accordance with an exemplary embodiment; as shown in fig. 1 to 3, an inner cylinder assembly includes: one end of the cylinder body 1 is arranged in an open manner, and the side wall of the cylinder body 1 is provided with a water through hole 11; the rear cover 2 is used for sealing one end of the opening of the cylinder body 1; the rear flange 3 is positioned in an accommodating space surrounded by the barrel 1 and the rear cover 2, the rear flange 3 is used for dividing the accommodating space into a water washing area and a water-free area, the water-free area is surrounded by the rear flange 3 and the rear cover 2, and the water through holes 11 are opened in the water washing area; and the tripod 4 is positioned in the water-free area.

For convenience of description, the present embodiment does not refer to the direction of the rear flange 3 toward the rear cover 2 as rear (the direction indicated by arrow a in fig. 1 and 3), and the direction of the rear flange 3 away from the rear cover 2 as front;

specifically, both ends of the cylinder 1 in the axial direction may be open, or only the rear end may be open. Illustratively, as shown in fig. 1, both ends of the cylinder 1 may be open (see fig. 1 and 3), a front flange 9 may be connected to the front end of the cylinder 1, and the outer circumference of the front flange 9 may be connected to the side wall of the cylinder 1.

Wherein, a space can be arranged between one side of the rear flange 3 close to the front flange 9 and the rear end surface of the cylinder body 1 so as to provide a space for the installation of the tripod 4.

Alternatively, the front flange 9 and the barrel 1 may be press-fitted into one piece by a spin-riveting process. Among them, spin riveting is also called cold roll riveting, which is a riveting method in which a rivet is locally pressurized by a rivet stem and continuously swung around the center until the rivet is formed. According to the cold rolling trajectory of the riveting method, the method can be divided into a pendulum rolling riveting method and a radial riveting method. The specific method can be selected as required.

In addition, when only the rear end of the drum 1 is open (this is not shown in the drawings), the front end of the drum 1 may be connected with a front wall, which may be provided with a central hole for putting in the laundry. That is, the front end of the cylinder 1 may be formed without the front flange 9 by integrally molding a front wall.

Specifically, the rear cap 2 may be attached to the rear end surface of the can 1 so as to be used to close the entire rear end opening of the can 1. The front end face of the rear flange 3 is spaced from the rear cover 2, so that a water-free region is formed between the rear flange 3 and the rear cover 2. The tripod 4 may be restricted between the rear flange 3 and the rear cover 2 so as to restrict the position of the tripod 4 in the axial direction of the cylinder 1.
