Definitions
- the present invention relates generally to a drum type washing machine, and more particularly to a drum type washing machine including a balancer capable of rapidly reducing vibration of a spin tub.
- a drum type washing machine rotates a drum so that the laundry loaded in the drum moves upward and then drops from the top to the bottom of the drum, thereby washing the laundry.
- the drum type washing machine includes a housing forming an external appearance of the drum type washing machine, a water reservoir accommodated in the housing to receive water therein, a spin tub rotatably installed in the water reservoir, and a driving motor generating rotational force by receiving electric power so as to rotate the spin tub connected to a rotating shaft of the driving motor.
- the drum type washing machine is provided with a shaft flange formed at the center thereof with a rotating shaft and fixed to a rear surface of the spin tub so as to uniformly transfer the rotational force of the driving motor to the rotating shaft, and a balancer fixed to the rear surface of the spin tub so as to rapidly reduce vibration generated when the spin tub is rotated.
- the shaft flange includes a hub section for installing the rotating shaft, and a plurality of arm sections extending radially outward from the hub section so as to be fixed to the rotating shaft.
- the balancer includes a balancer housing formed with an annular race that allows a mass accommodated in the balancer housing to move in the circumferential direction, and a ball movably installed in the annular race so as to serve as the mass.
- the balancer housing includes first and second balancer housings coupled to each other through fusion welding while forming the race therebetween.
- the ball accommodated in the balancer housing is subject to centrifugal force during the rotation of spin tub, so the ball repeatedly collides with the first and second balancer housings. If the ball applies such impact to the first and second balancer housings for a long period of time, the connection part between the first and second balancer housings is weakened, so that the first balancer housing is separated from the second housing. In this case, the ball accommodated in the race of the balancer housing may move out of the race.
- US 5,850,748 A discloses a balancer and its body formed between a side panel of a tub and a secondary plate member. It is also possible that the balancer comprises the first and a second plate member. Those form an annular shaped body coupled to a groove of the spin tub. The annular shaped body has no quadrilateral space and the balancer has no annular shaped body coupled to an annular groove as there are corresponding plate members which form a radially inner chamber and a radially outer chamber by the cooperation of the plate members.
- EP 0 806 515 A1 discloses a front panel which has a first groove and which is then connected to a cover to provide a balancer housing. This means the balancer housing or the corresponding body of the balancer is formed by part of the spin tub and a cover fixed thereto.
- an object of the present invention is to provide a drum type washing machine capable of preventing a ball accommodated in a balancer from moving out of the balancer, even if the balancer is broken due to long-period use of the balancer.
- a spin tub may include a spin tub body having a cylindrical shape and a rear surface of which is opened, and a rear cover covering the rear surface of the spin tub body, a part of a rear end portion of the spin tub body protrudes toward a rear side of the rear cover, and an outer end portion of the shaft flange is fixed to the part of the rear end portion of the spin tub body that protrudes toward the rear side of the rear cover.
- a support section can be provided at an outer peripheral end portion of the rear cover, in which the support section extends rearward in parallel to the spin tub body such that an outer peripheral surface of the rear balancer is supported by the support section and an outer peripheral end portion of the shaft flange is fixed to the support section.
- An annular groove is be formed at the outer peripheral end portion of the rear cover so as to receive the rear balancer, and the rear balancer is rested in the annular groove by means of the shaft flange.
- the rear balancer includes first and second balancer housings having annular shapes and being coupled to each other such that a race, in which a plurality of balls are movably installed, is formed between the first and second balancer housings.
- the drum type washing machine includes a housing 10 having a box shape forming an external appearance of the drum type washing machine, a water reservoir 30 accommodated in the housing 10 to receive water therein, a spin tub 40 rotatably installed in the water reservoir 30 and having a cylindrical structure formed with a plurality of pores 40b allowing water and air to pass through the spin tub 40, and a driving motor 50 transferring power to the spin tub 40 so as to rotate the spin tub 40 such that the laundry contained in the spin tub 40 can be washed and dehydrated.
- Openings 30a and 40a are formed at front center portions of the water reservoir 30 and the spin tub 40 so as to allow the user to put the laundry into the spin tub 40 or to take out the laundry from the spin tub 40.
- a door 20 is hinged to the front surface of the housing 10 so as to open/close the openings 30a and 40a of the water reservoir 30 and the spin tub 40.
- Lifters 40c are provided on the inner peripheral wall of the spin tub 40 at a predetermined interval. As the spin tub 40 rotates in the forward and reverse directions, the laundry placed in the spin tub 40 is moved upward and then dropped downward in the spin tub 40 by means of the lifters 40c, so that the laundry is washed.
- the spin tub 40 includes a spin tub body 41 having a cylindrical shape and being installed lengthwise along the spin tub 40, in which front and rear surfaces of the spin tub body 41 are opened, and covers 42 and 43 covering the front and rear surfaces of the spin tub body 41.
- the covers 42 and 43 include a front cover 42 (see FIG. 2 ) covering the front surface of the spin tub 40 and being formed at the center thereof with the opening 40a so as to allow the user to put the laundry into the spin tub 40, and a rear cover 43 covering the rear surface of the spin tub 40 and being provided at the center thereof with a rotating shaft 53 that transfers driving force of the driving motor 50.
- the driving motor 50 includes a stator unit 51 fixed to the rear surface of the water reservoir 30, a rotor unit 52 rotatably installed around the stator unit 51, and a rotating shaft 53 having a first end installed at the rotor unit 52 and a second end installed at the rear cover 43 forming the rear surface of the spin tub 40 by passing through the water reservoir 30.
- a shaft flange 60 provided at the center thereof with the rotating shaft 53 is fixed to the rear surface of the spin tub 40 so as to uniformly transfer the rotational force of the driving motor 50 to the spin tub 40, so that the spin tub 40 is rotated by receiving the rotational force of the driving motor 50 through the shaft flange 60.
- the shaft flange 60 uniformly transfers the rotational force of the driving motor to various portions of the spin tub 40, thereby preventing excessive force from being transferred to a specific part of the spin tub 40.
- the shaft flange 60 includes a hub section 61 for fixedly installing the rotating shaft 53, and a plurality of arm sections 62 extending radially outward from the hub section 61 so as to be fixed to the outer peripheral end portion of the spin tub 40 while being spaced apart from each other in the circumferential direction at a predetermined interval.
- the shaft flange 60 has three arm sections 62. The rotational force of the driving motor 50 is uniformly transferred to three spots of the outer peripheral end portion of the spin tub 40 through the three arm sections 62.
- the front and rear covers 42 and 43 that form the front and rear surfaces of the spin tub 40 are provided with balancers 70F and 70R, respectively.
- the balancers 70F and 70R rapidly reduce vibration of the spin tub 40, which is generated during the rotation of the spin tub due to unbalance of the laundry placed in the spin tub, thereby stabilizing the rotation of the spin tub 40 in the early stage.
- the balancer 70F installed at the front side of the spin tub 40 is referred to as a front balancer 70F and the balancer 70R installed at the rear side of the spin tub 40 is referred to as a rear balancer 70R.
- a mass is installed in the balancers 70F and 70R in such a manner that the mass can move in the circumferential direction of the balancers 70F and 70R. If the unbalance occurs due to the weight of laundry placed in the spin tub 40, the mass accommodated in the balancers 70F and 70R moves in the circumferential direction so as to compensate for the unbalance. Thus, the vibration of the spin tub 40 caused by the unbalance mass can be rapidly reduced.
- the rear balancer 70R installed at the rear cover 43 includes first and second balancer housings 71 and 72 having an annular shape and being coupled with each other such that a race 73, which is a moving route of the mass, can be formed therebetween, and a plurality of balls 74 is movably installed in the race 73 so as to serve as the mass.
- the first balancer housing 71 may be coupled with the second balancer housing 72 through fusion welding, etc.
- the drum type washing machine of the present invention at least a part of the rear balancer 70R is supported on the rear surface of the rear cover 43 by means of the shaft flange 60, so that the front and rear surfaces of the rear balancer 70R are supported on the rear surface of the rear cover 43 and the front surface of the arm section 62 of the shaft flange 60, respectively.
- the first and second balancer housings 71 and 72 can be secured to each other. Since the first balancer housing 71 can be secured to the second balancer housing 72, the balls 74 installed in the rear balancer 70R can be prevented from moving out of the rear balancer 70R.
- the shaft flange 60 includes three arm sections 62, so at least three spots of the rear balancer 70R are supported by means of the three arm sections 62.
- a groove 43a is formed in the rear cover 43.
- the groove 43a has an annular shape corresponding to the shape of the rear balancer 70R such that the rear balancer 70R can be rested in the groove 43a.
- a part of the rear end portion of the spin tub body 41 protrudes toward the rear side of the rear cover 43, so that the end portion of the arm section 62 of the shaft flange 60 is fixed to the protruding part of the rear end portion of the spin tub body 41, as shown in FIG. 3 . Accordingly, the rear balancer 70R can be stably installed in the groove 43a by means of the arm section 62 of the shaft flange 60.
- a supporter 43b is provided at the outer peripheral end portion of the rear cover 43.
- the supporter 43b extends in the rear direction in parallel to the spin tub body 41 and the outer peripheral surface of the rear balancer 70R is supported on the inner surface of the supporter 43b and the end portion of the arm section 62 is fixed to the inner surface of the supporter 43b.
- FIG. 4 is an exploded perspective view showing the arrangement of a rear balancer 70R and a shaft flange 80 provided in a drum type washing machine according to a second embodiment of the present invention.
- the rear balancer 70R applied to the drum type washing machine according to a second embodiment of the present invention includes first and second balancer housings 71 and 72 having an annular shape and being coupled with each other such that a race 73, which is a moving route of the mass, can be formed therebetween, and a plurality of balls 74 movably installed in the race 73 so as to serve as the mass.
- the shaft flange 80 includes a hub section 81 for installing the rotating shaft 53, and a plurality of arm sections 82 extending radially outward from the hub section 81 while being spaced apart from each other in the circumferential direction at a predetermined interval.
- first and second balancer housings 71 and 72 constituting the rear balancer 70R is installed on the shaft flange 80 such that the first and second balancer housings 71 and 72 are supported against each other.

- balancer supports 83 which are opened toward the rear surface of the spin tub 40 so as to support the rear balancer 70R installed thereon, are provided at outer end portions of the shaft flange 80.
- the balancer supports 83 extend from end portions of the arm sections 82 of the shaft flange 80 and are formed with mounting grooves 83a which are opened toward the rear surface of the spin tub 40 so as to mount the rear balancer 70R thereon.
- end portions of the balancer supports 83 are fixed to the spin tub 40 by means of a coupling member, such as a bolt, so that the shaft flange 80 can be fixed to the spin tub 40 through the balancer supports 83.
- the shaft flange 80 includes three arm sections 62 and three balancer supports 83 extend from end portions of three arm sections 62.
- three balancer supports 83 extend from end portions of three arm sections 62.
- FIG. 5 parts of three spots of the rear balancer 70R are rested in the mounting grooves 83a formed in three arm sections 82, respectively. Therefore, since the parts of three spots of the rear balancer 70R are rested in the mounting grooves 83a, the front, rear, outer peripheral and inner peripheral surfaces of the rear balancer 70R are supported by the rear surface of the spin tub 40 and the inner surfaces of the mounting grooves of the shaft flange 80.
- the first and second balancer housings 71 and 72 can be secured to each other, thereby preventing the balls 74 from moving out of the race 73.
- the rotational center of the rear balancer 70R precisely matches with the rotational center of the rotating shaft 53. Accordingly, there is no need to perform precision work for matching the rotational center of the rear balancer 70R with the rotational center of the rotating shaft 53, so that assembly work for the drum type washing machine can be simplified.
- a cross section of the annular shaped body of the balancer (70F, 70R) comprises an inner wall and an outer wall facing the inner wall, which outer wall is disposed farther from the centre of the balancer (70F, 70R) than the inner wall, a first connecting wall and a second connecting wall formed between the inner wall and the outer wall to define said internal quadrilateral space, wherein the outer wall contacting the balls (74) contained therein during rotation of the spin tub (40) is formed as an undivided and unitary piece.
- a depth of the annular groove (43a) for accommodating the annular shaped body of the balancer (70F, 70R) is selected such that at least a centre of each of the balls (74) contained in the annular shaped body is disposed completely within the annular groove.
- FIG. 6 is an exploded perspective view showing the arrangement of a balancer and a shaft flange provided in a drum type washing machine according to a third embodiment of the present invention.
- the shaft flange 90 provided in the drum type washing machine includes a hub section 91 for installing the rotating shaft 53, a plurality of arm sections 92 extending radially outward from the hub section 91 while being spaced apart from each other in the circumferential direction, and a balancer support 93 extending in the circumferential direction while connecting outer end portions of the arm sections 92 to each other such that the rear balancer 70R can be installed on the balancer support 93.
- the balancer support 93 is formed with an annular groove 93a which is opened toward the rear surface of the spin tub 40.
- the annular groove 93a is formed in the balancer support 93 for mounting the rear balancer 70R, the front, rear, outer peripheral and inner peripheral surfaces of the rear balancer 70R are wholly supported by the rear surface of the spin tub 40 and the inner surface of the annular groove 93a. Accordingly, even if the connection part between the first and second balancer housings 71 and 72 is broken, the first and second balancer housings 71 and 72 can be secured to each other, thereby preventing the balls 74 from moving out of the race 73. In addition, impact caused by collision of balls 74 is partially transferred to the balancer support 93, so that impact applied to the first and second balancer housings 71 and 72 can be reduced. Thus, the connection part between the first and second balancer housings 71 and 72 can be protected from breakage.
- the balancer since the balancer is supported on the rear surface of the spin tub by means of the shaft flange, the balls accommodated in the balancer can be prevented from moving out of the balancer, even if the balancer is broken due to long-period use.
- the balancer is mounted on the shaft flange provided at the center thereof with the rotating shaft, so that the rotational center of the balancer can be easily matched with the rotational center of the rotating shaft.
