Detailed ways

Embodiments of the invention will be described in detail below, examples of the invention are shown in the accompanying drawings, in which like reference numerals refer to like elements throughout. The following description of the embodiments is intended to illustrate the present invention by referring to the figures.

1 is a longitudinal sectional view of a drum washing machine according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view showing the structure of a drum front of the drum washing machine shown in FIG. 1. Referring to FIG.

As shown in Figure 1, the drum washing machine of the first embodiment of the present invention includes a casing 1 forming the appearance of the drum washing machine, a tub 2 installed in the casing 1 for containing washing water, and a tub 2 rotatably installed in the tub 2 for containing A drum 20 for laundry, and a door 3 hinged to the open front surface of the casing 1 .

A water supply pipe 4 for supplying washing water and a detergent supply device 5 for supplying detergent are arranged above the tub 2, and a drain pipe 6 for draining the washing water contained in the tub 2 out of the casing 1 after washing is finished. And drain pump 7 is arranged on the below of barrel 2.

The rotating shaft 8 is connected to the outer surface of the rear part of the drum 20 and extends out of the barrel 2 , and the driving motor 9 connected to the rotating shaft 8 is installed outside the barrel 2 . A bearing member 10 is installed at the central portion of the rear surface of the tub 2, and the rotating shaft 8 passes through and is rotatably supported by the bearing member 10. As shown in FIG.

As mentioned above, one end of the rotating shaft 8 is connected with the rear outer surface of the drum 20, the central part of the rotating shaft 8 is rotatably supported by the bearing member 10, and the other end of the rotating shaft 8 is connected with the driving motor 9, and the driving motor 9 It is then connected to the rear outer surface of the barrel 2 . Therefore, the drum 20 can rotate in the tub 2 driven by the drive motor 9 .

The barrel 2 is cylindrical and supported by a plurality of shock absorbers 11 mounted on the bottom of the casing 1 . The barrel 2 is installed in the housing 1 such that the front end of the barrel 2 facing the door 3 is higher than the barrel rear end on which the drive motor 9 is mounted.

The drum 20 is obliquely disposed in the tub 2 in the same manner as the tub 2 , and includes a cylindrical body 21 with an open front surface and an opening 22 extending from the open front surface of the body 21 toward the door 3 . Therefore, the height of the front end of the drum 20 is higher than that of the rear end of the drum 20 , and the user can put the clothes into the drum 20 or take out the clothes from the drum 20 without bending down.

A plurality of dehydration holes 23 are formed through the main body 21 of the drum 20 . During the washing operation, the dehydration hole 23 can make the water contained in the bucket 2 flow into the drum 20, thereby washing clothes with the washing water dissolved in detergent; Bucket 2, so that the washing water is discharged from the shell 1 through the drain pipe 6.

A plurality of axially extending lifters 24 are installed on the main body 21 and are spaced apart from each other at predetermined intervals. During the washing operation, the drum 20 is repeatedly rotated in forward and reverse directions, whereby the lifter 24 lifts the laundry to a predetermined height and drops the laundry, thereby washing the laundry quickly and efficiently. Thus, when the driving motor 9 operates, the rotating shaft 8 rotates together with the drum 20, thereby performing washing, rinsing and dehydration operations of the drum washing machine.

A plurality of protrusions 30 are formed on the opening 22 of the drum 20, and the opening 22 is used as an entrance for putting or taking out clothes into or out of the main body 21 of the drum 20, and these protrusions 30 enable the user to The drum 20 is turned manually.

In FIG. 2, the protrusion 30 has a cylindrical structure protruding from the inner cylindrical surface of the opening 22, and has a circular cross-section of a predetermined size. In addition, the protrusions 30 are arranged in a plurality of rows in the lateral direction of the drum 20 .

The protrusions 30 are arranged in a plurality of straight lines, and the plurality of rows of protrusions 30 formed on the inner cylindrical surface of the opening 22 are separated from each other at predetermined intervals in the circumferential direction. In this way, the user can easily manually push the protrusion 30 to rotate the drum 20 .

These protrusions 30 are integrally molded with the opening 22 by press working when the drum 20 is manufactured.

Alternatively, these protrusions 30 may be manufactured separately from the opening 22 and then mounted on the inner cylindrical surface of the opening 22 .

Therefore, when the laundry is finished, the user opens the door 3 and utilizes the protrusion 30 protruding from the inner cylindrical surface of the opening 22 to easily turn the drum 20, thereby easily and quickly attaching the inner cylindrical surface of the main body 21 of the drum 20. The clothes at various positions are taken out from the drum 20 to the outside of the casing 1 .

3 shows a longitudinal sectional view of a drum washing machine according to a second embodiment of the present invention; FIG. 4 shows an exploded perspective view of a drum front of the drum washing machine shown in FIG. 3 .

As shown in FIGS. 3 and 4 , except that the shapes of the protrusions 30 a formed on the opening 22 of the drum 20 are different from the shapes of the protrusions 30 shown in FIGS. 1 and 2 , the second embodiment of the present invention The drum washing machine of the embodiment has the same structure as the drum washing machine of the first embodiment of the present invention. Therefore, only the configuration of the protrusion 30a will be described below.

As shown in FIGS. 3 and 4 , a protrusion 30 a having a predetermined height and length is provided on an inner cylindrical surface of the opening 22 in a lateral direction of the drum 20 . That is, the projections 30a are approximately rectangular in cross section, have a small width and a large length, and the projections 30a are separated from each other at predetermined intervals along the inner cylindrical surface of the opening 22 . Therefore, the user can easily turn the drum 20 by turning the protrusion 30a while grasping the protrusion 30a.

The same as the protrusion 30 of the front-loading washing machine in the embodiment shown in FIGS. 1 and 2 , the protrusion 30 a of the front-loading washing machine in the second embodiment can be molded integrally with the opening 22 through a molding process when manufacturing the drum 20 , or can be Manufactured separately from opening 22 and mounted to the inner cylindrical surface of opening 22 .

As apparent from the above description, the present invention provides a drum washing machine in which the drum can be easily rotated by utilizing a plurality of protrusions formed along the inner cylindrical surface of the drum opening, thereby enabling the user to reach The laundry at multiple locations on the inner cylindrical surface of the drum, thereby allowing the user to easily and quickly remove the laundry from the drum.

In addition, since the drum of the drum washing machine of the present invention is inclined so that the front end of the drum is higher than the rear end of the drum, the drum washing machine allows the user to put clothes in or out of the drum without bending over, thereby Helps to load and remove laundry from the drum.

Although only a small number of embodiments of the present invention have been shown and described, those skilled in the art should recognize that changes can be made to the embodiments of the present invention without departing from the principle and spirit of the present invention. as defined by the claims and their equivalents.
