Description

Barrel cover structure of outer barrel of pulsator washing machine

Technical Field

The utility model relates to a rotary drum washing machine field specifically is a bung structure of outer bucket of rotary drum washing machine.

Background

The washing machine is a very important member in household appliances at present, almost every household can use the washing machine, and a lot of manpower and labor can be saved. Common washing machines comprise a pulsator washing machine and a drum washing machine, the pulsator washing machine mainly comprises a box body, an outer barrel, an inner barrel and a pulsator, the outer barrel is fixedly arranged in the box body, the inner barrel is rotatably arranged in the outer barrel, a barrel cover is fixedly arranged at the top of the outer barrel, the barrel cover is annular, the barrel cover is used for shielding the upper edge of the inner barrel, clothes are prevented from entering an interlayer between the outer barrel and the inner barrel, the pulsator is rotatably arranged at the bottom of the outer barrel and stretches into the barrel bottom of the inner barrel, and convex ribs are arranged inside the barrel bottom. When washing clothes, the inner barrel is not moved, and the clothes are stirred by the impeller and rubbed with the convex ribs to achieve the aim of cleaning; during spin-drying, the inner barrel drives the clothes to rotate, so that the moisture on the clothes is separated from the clothes under the action of centrifugal force. The impeller washing machine realizes cleaning of clothes only by stirring of the impeller and friction of the impeller and the bottom convex ribs, and has the technical problem of low cleaning rate.

Disclosure of Invention

To current rotary drum washing machine when the laundry, the clothing only relies on the stirring of impeller and realizes cleanly with the friction of the protruding muscle in bottom, has the lower technical problem of cleaning, the utility model provides a bung structure of outer bucket of rotary drum washing machine, it can improve the washing ratio of clothing when the laundry.

The technical scheme is as follows: the utility model provides a bung structure of outer bucket of rotary drum washing machine, its is including being annular bung body, its characterized in that: the inner ring is detachably mounted on the annular inner hole of the barrel cover body, at least two convex ribs are arranged on the bottom surface of the inner ring along the circumferential direction of the inner ring, and the convex ribs are long-strip-shaped and are arranged along the radial direction of the inner ring.

It is further characterized in that:

the quantity of fin is 5~20 and follows the circumference equipartition setting of inner ring.

At least three L-shaped grooves are formed in one side, close to an annular inner hole, of the top surface of the barrel cover body along the circumferential direction of the barrel cover body, plate-shaped protrusions with the same number as the L-shaped grooves are formed in the outer ring surface of the inner ring along the circumferential direction of the inner ring, the plate-shaped protrusions are horizontally arranged, and the plate-shaped protrusions can be inserted into the vertical grooves of the L-shaped grooves in a clearance fit mode and are clamped into the horizontal grooves of the L-shaped grooves when the inner ring rotates horizontally.

The outer side surface of the plate-shaped bulge is an arc-shaped surface.

The horizontal rotation direction is consistent with the rotation direction of the impeller washing machine during washing.

The inner ring is of a conical ring structure, and the diameter of the upper part of the inner ring is larger than that of the lower part of the inner ring.

The half cone angle of the conical ring is 70-80 degrees.

The utility model has the advantages that:

the utility model discloses a bung structure of outer bucket of rotary drum washing machine, it has set up the detachable inner ring on the bung body, and set up the fin on inner ring's bottom surface, the fin is rectangular shape and follows the radial setting of inner ring, before the laundry, pull down the inner ring earlier, put into the washing machine with the clothing, inner ring on the repacking, thereby during the laundry, the clothing not only can lean on the stirring of impeller and with interior bucket bottom protruding friction between the muscle reach cleanly, can also reach cleanly with the fin striking friction of inner ring bottom rotating the in-process, effectively improve the washing ratio of clothing.
