Abstract
Description
- The present invention relates to a drum type washing machine, and, more particularly, to a drum type washing machine, which can reduce damage of a shaft system serving to transmit rotational force of a motor to a drum, and a method for assembling the shaft system thereof.
- Generally, a washing machine is an apparatus which washes laundry using electric power. The washing machine can be generally classified into a vertical type washing machine which has a rotating tub installed vertically in a body, and a drum type washing machine which has the rotating tub installed horizontally therein. The drum type washing machine comprises a drum positioned horizontally therein such that, as the drum rotates alternately in the clockwise direction and the counterclockwise direction, laundry can be washed while moving up and down along with water in the inner portion of the rotating tub.
- The drum type washing machine generally comprises a motor to supply power to rotate the drum, and a shaft system to transmit rotational force of the motor to the drum. FIG. 1 is a perspective view illustrating a drum, and a shaft system of a conventional drum type washing machine. As shown in FIG. 1, a
shaft system 1 of the drum type washing machine comprises aflange shaft 3 installed at a rear side of adrum 2, and adrum rotating shaft 4 inserted into and integrally formed with the center of theflange shaft 3. Here, theflange shaft 3 comprises a plurality of wings 3a, each of which extends radially from the center, and has a distal end fixed to thedrum 2 by means of a fastening member such as a bolt 5. - Accordingly, when the
drum rotating shaft 4 is rotated by a motor (not shown), rotational force is transmitted to theflange shaft 3 integrally formed with thedrum rotating shaft 4, and is then delivered to thedrum 2 connected with theflange shaft 3 via the bolts 5, so that thedrum rotating shaft 4, theflange shaft 3, and thedrum 2 perform the same rotational movement. - However, since the
flange shaft 3 is assembled at the distal end of each wing 3a to the drum only by the bolts 5 in the conventional washing machine, there is a problem in that load of the laundry is concentrated on a specific portion of the shaft system of the washing machine instead of being adequately distributed. Additionally" if the laundry is biased to one side of the drum while the drum is rotated, a centrifugal force is invoked by the rotating laundry, applying unequal load to the drum. The unequal load is transmitted to theshaft system 1 via fastening portions of the bolts at the distal end of theflange shaft 3, and concentrated on a portion where theflange shaft 3 is coupled to thedrum rotating shaft 4, so that theflange shaft 3 and thedrum rotating shaft 4 are damaged due to fatigue. Furthermore, since theshaft system 1 of the conventional washing machine does not have a self-buffering system to allow reduction of vibration by itself, theshaft system 1 is damaged due to vibration and/or noise is generated therefrom. Such problem is especially evident when the drum rotates at high speeds and/or when the laundry load is heavy. - Accordingly, it is an aspect of the present invention to provide a drum type washing machine, which can reduce damage of a shaft system caused by load applied thereto, and a method for assembling the shaft system thereof.
- It is another aspect of the present invention to provide the drum type washing machine, which can reduce damage and noise of the shaft system due to vibration being generated upon rotation of a drum, and the method for assembling the shaft system thereof.
- Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the invention.
- The foregoing and other aspects of the present invention are achieved by providing a drum type washing machine, comprising a drum, a motor to rotate the drum, and a flange shaft coupled to a rear side of the drum to transmit rotational force of the motor to the drum, wherein a buffering material is provided between the drum and the flange shaft to distribute or absorb load or vibration transmitted from the drum to the flange shaft.
- The buffering material may fill up a gap formed between the drum and the flange shaft to bond the drum and the flange shaft.
- The buffering material may comprise a material having a liquid phase initially and changing to a solid phase having elasticity a predetermined period of time after contacting air. The buffering material may comprise a silicon material.
- The flange shaft may be formed with a recess to be filled with the buffering material.
- In accordance with another aspect of the present invention, there is provided a method for assembling a shaft system of a drum type washing machine in which the shaft system comprises a flange shaft installed at a rear side of a drum to transmit rotational force of a motor to the drum, and a drum rotating shaft, the method comprising: applying a buffering material to a portion at the rear side of the drum corresponding to an installation position of the flange shaft; and installing the flange shaft to the drum having the buffering material applied thereto.
- In accordance with yet another aspect of the present invention, there is provided a method for assembling a shaft system of a drum type washing machine in which the shaft system comprises a flange shaft installed at a rear side of a drum to transmit rotational force of a motor to the drum, and a drum rotating shaft, the method comprising: applying a buffering material to a surface of the flange shaft brought into contact with the drum; and installing the flange shaft having the buffering material to the drum.
- These and/or other aspects and advantages of the invention will become apparent and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings, of which:
- FIG. 1 is a perspective view illustrating a drum, and a shaft system of a conventional drum type washing machine;

- FIGS. 5 and 6 are perspective views illustrating a shaft system assembled to the drum of the washing machine in accordance with the present invention.
- Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments are described below to explain the present invention by referring to the figures.
- FIG. 2 is a perspective view illustrating an appearance of a drum type washing machine in accordance with the present invention, and FIG. 3 is a side sectional view illustrating the construction of the drum type washing machine.
- Referring to FIGS. 2 and 3, a drum type washing machine according to the present invention comprises a
housing 10 defining an outer appearance of the washing machine, awater tub 11 installed in thehousing 10 to contain water for washing laundry, and adrum 12 rotatably installed in thewater tub 11 to receive the laundry which will be washed by operation of the washing machine therein. Thehousing 10 has adoor 13 attached to a front side thereof to open or close an opening through which the laundry is accessed, and acontrol panel 14 provided at the front side to control the operation of the washing machine. - The
housing 10 is provided at an upper portion therein with awater supply pipe 15 and adetergent supply device 16 to supply water and detergent to thetub 11, respectively, and provided at a lower portion therein with awater discharge pump 17 and awater discharge pipe 18 to discharge water from thetub 11 to an outside of thehousing 10. - The
housing 10 is further provided with amotor 20 at an outside of thetub 11 to rotate thedrum 12 in the clockwise direction or the counterclockwise direction, and ashaft system 30 at an outside of arear side 12a of thedrum 12. Theshaft system 30 comprises aflange shaft 31, and adrum rotating shaft 32 to transmit rotational force of themotor 20 to thedrum 12. Thedrum rotating shaft 32 is coupled to the center of theflange shaft 31, and extends outwardly from thetub 11 so as to engage with themotor 20. Theflange shaft 31 has a plurality ofwings 33, each of which extends radially from the center of theflange shaft 31 coupled to thedrum rotating shaft 32, and has a distal end fixed to thedrum 12 by means of a fastening member such as abolt 34. - A cylindrical bearing
housing 21 is provided at the rear side of thetub 11, and hasbearings 22 on thedrum rotating shaft 32 such that thedrum rotating shaft 32 can be rotatably supported thereby. - Accordingly, as the
drum rotating shaft 32 is rotated by themotor 20, theflange shaft 31 coupled to thedrum rotating shaft 32 is also rotated, so that thedrum 12 coupled to theflange shaft 31 is rotated, causing the laundry to be washed or extracted of water therein. In the meantime, if unequal load is applied because the laundry is biased to one side of thedrum 12 during rotation of thedrum 12, or if vibration is generated due to high speed rotation of thedrum 12, the load and vibration are transmitted to theshaft system 30, and accumulate fatigue on theflange shaft 31 and thedrum rotating shaft 32. - In this regard, the drum type washing machine of the present invention comprises a
buffering material 40 between the drum and theflange shaft 31 to distribute or absorb the load or the vibration transmitted from thedrum 12 to theflange shaft 31. - FIG. 4 is an enlarged view of Part A of FIG. 3 for illustrating a gap between a drum and a flange shaft excluding a buffering material, and FIGS. 5 and 6 are perspective views illustrating a shaft system assembled to the drum of the washing machine in accordance with the present invention.
- As shown in FIGS. 3 and 4, a
buffering material 40 serves to allow thedrum 12 and theflange shaft 31 to be bonded to each other over a wide contact area by filling up a gap G created between thedrum 12 and theflange shaft 31 when assembling theshaft system 30. Then, when load is transmitted from thedrum 12 to theshaft system 30, the load is transmitted in a distributed state over the wide contact area via thebuffering material 40 rather than in a concentrated state on abolt fastening portion 35 of theflange shaft 31, thereby reducing stress applied to theflange shaft 31 due to the load. In addition, when vibration is transmitted to theshaft system 30 due to the rotation of thedrum 12, thebuffering material 40 absorbs the vibration between thedrum 12 and theshaft system 30, thereby reducing damage or noise of the shaft system due to the vibration. Although preferably, the entire gap portion is filled with the buffering material, certain portions may be left empty. - In consideration of the structural characteristics or the weight of the
flange shaft 31, arecess 36 is formed on theflange shaft 31, and filled with thebuffering material 40 such that theflange shaft 31 and thedrum 12 are bonded to each other over the wide contact area via thebuffering material 40. - In order to allow the
buffering material 40 to effectively fill up the gap G between thedrum 12 and theflange shaft 31 while allowing thebuffering material 40 to effectively reduce the vibration transmitted from thedrum 12 therethrough, thebuffering material 40 is preferably composed of a material, which has a liquid phase initially, i.e., before being applied to therecess 36, and changes to a solid phase with a predetermined elasticity in a state of contacting air. For example, such a material includes silicon materials such as a silicon bond, a silicon rubber, and the like. However, thebuffering material 40 is not limited to the silicon materials, but any other types of material having the properties as described above may be used for thebuffering material 40. - As shown in FIGS. 3 and 5, when assembling the
shaft system 30 to thedrum 12, thebuffering material 40 is applied to a portion at therear side 12a of thedrum 12 corresponding to an installation position of theflange shaft 31. Then, theflange shaft 31 is mounted to thedrum 12 having thebuffering material 40 applied thereto such that thebuffering material 40 fills up the gap between thedrum 12 and theflange shaft 31. - Alternatively, as shown in FIGS. 3 and 6, it is possible to assemble the
shaft system 30 to thedrum 12 in such a manner that, after applying thebuffering material 40 to arear surface 31 a of theflange shaft 31, that is, a surface of theflange shaft 31 which will be brought into contact with thedrum 12, theflange shaft 31 having thebuffering material 40 applied thereto is mounted to thedrum 12. - As apparent from the above description, the present invention has an advantageous effect in that, when the buffering material applied to the drum or the flange shaft of the shaft system, it causes the load to be distributed and absorbs the vibration transmitted from the drum to the shaft system upon rotation of the drum, thereby reducing damage or noise of the shaft system.
- Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that various modifications, additions and substitutions may be made in these embodiments without departing from the principle and spirit of the invention, the scope of which is defined in the claims and their equivalents.
